Real-time is the highest priority class available to a process. Therefore, it is different from 'High' in that it's one step greater, and 'Above Normal' in that it's two steps greater.

Similarly, real-time is also a thread priority level.

The process priority class raises or lowers all effective thread priorities in the process and is therefore considered the 'base priority'.

So, a process has a:

1. Base process priority class.
2. Individual thread priorities, offsets of the base priority class.

Since real-time is supposed to be reserved for applications that absolutely must pre-empt other running processes, there is a special security privilege to protect against haphazard use of it. This is defined by the security policy.

In NT6+ (Vista+), use of the Vista Multimedia Class Scheduler is the proper way to achieve real-time operations in what is not a real-time OS. It works, for the most part, though is not perfect since the OS isn't designed for real-time operations.

Microsoft considers this priority very dangerous, rightly so. No application should use it except in very specialized circumstances, and even then try to limit its use to temporary needs.

reload is a builtin in Python 2, but not in Python 3, so the error you're seeing is expected.

If you truly must reload a module in Python 3, you should use either:

• importlib.reload for Python 3.4 and above
• imp.reload for Python 3.0 to 3.3 (deprecated since Python 3.4 in favour of importlib)

Another potential cause for this (Intellij was involved in my case, not sure that mattered though): trying to merge in changes from a main branch into a branch off of a feature branch.

In other words, merging "main" into "current" in the following arrangement:

main
  |
  --feature
      |
      --current

I resolved all conflicts and GiT reported unmerged files and I was stuck until I merged from main into feature, then feature into current.

You're so close it's crazy.

if($(this).attr("name"))

There's no hasAttr but hitting an attribute by name will just return undefined if it doesn't exist.

This is why the below works. If you remove the name attribute from #heading the second alert will fire.

Update: As per the comments, the below will ONLY work if the attribute is present AND is set to something not if the attribute is there but empty

<script type="text/javascript">
$(document).ready(function()
{
    if ($("#heading").attr("name"))
      alert('Look, this is showing because it\'s not undefined');
    else
      alert('This would be called if it were undefined or is there but empty');
});
</script>
<h1 id="heading" name="bob">Welcome!</h1>

Even better than Gayan Dissanayake pointed out.

/^[-\w\s]+$/

Now ^[a-zA-Z0-9]+$ can be represented as ^\w+$

You may want to use \s instead of space. Note that \s takes care of whitespace and not only one space character.

MessageBox.Show(

It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.

Changing the version in the pom.xml should fix the problem

Let's make it simple:

df[nrow(df) + 1,] = c("v1","v2")

use this:

pil_image = PIL.Image.open('Image.jpg').convert('RGB') 
open_cv_image = numpy.array(pil_image) 
# Convert RGB to BGR 
open_cv_image = open_cv_image[:, :, ::-1].copy() 

I have another option in this situation. My list is objList, and I have to order but nulls must be in the end. my decision:

var newList = objList.Where(m=>m.Column != null)
                     .OrderBy(m => m.Column)
                     .Concat(objList.where(m=>m.Column == null));

If it was working before and suddenly stopped working:

This issue can be caused because sometimes ssh-agent is not persistent across reboots. You should check if ssh-agent has your key added:

ssh-add -l -E md5

if you get the output like:

The agent has no identities.

it means ssh-agent has lost your key. In that case, you simply need to add the identity key again. Something like:

ssh-add ~/.ssh/git_rsa

The error should disappear now!

My answer is in reference to the setting-up of go-lang on Ubuntu linux/amd64.I have faced the same trouble of setting the path of environment variables (GOPATH and GOBIN), losing it on terminal exit and rebuilding it using the source <file_name> every time.The mistake was to put the path (GOPATH and GOBIN) in ~/.bash_profile folder. After wasting a few good hours, I found that the solution was to put GOPATH and GOBIN in ~/.bash_rc file in the manner:

export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOPATH:$GOBIN

and doing so, the go installation worked fine and there were no path losses.

EDIT 1: The reason with which this issue can be related is that settings for non-login shells like your ubuntu terminal or gnome-terminal where we run the go code are taken from ~./bash_rc file and the settings for login shells are taken from ~/.bash_profile file, and from ~/.profile file if ~/.bash_profile file is unreachable.

You'll want to use the GetExtensionName method on the FileSystemObject object.

Set x = CreateObject("scripting.filesystemobject")
WScript.Echo x.GetExtensionName("foo.pdf")

In your example, try using this

For Each objFile in colFiles
    If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
        Wscript.Echo objFile.Name
    End If
Next

Try this. Your markup:

<div id="MyId" runat="server">some content</div>

.. and in aspx.cs file:

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["someSessionVal"].ToString() == "some value")
    {
        MyId.Visible = true;
    }
    else
    {
        MyId.Visible = false;
    }
}

border radius is good option, if struggling with old IE versions then try HTML codes

and use css to change color. Output:

Firstly, on Unix you use mount, not ls /mnt: many things are not mounted in /mnt.

Anyhow, there's the mountvol DOS command, which continues to work in Powershell, and there's the Powershell-specific Get-PSDrive.

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

If you use Android default action bar then. If you change from java then some time show previous color.

Example

Then your action bar code inside "app_bar_main". So go inside app_bar_main.xml and just add Background.

Example

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

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="#33691e"   <!--use your color -->
        app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main1" />

You can use Apache Commons.

In the IOUtils you can find the toString method with three helpful implementations.

public static String toString(InputStream input) throws IOException {
        return toString(input, Charset.defaultCharset());
}

public static String toString(InputStream input) throws IOException {
        return toString(input, Charset.defaultCharset());
}

public static String toString(InputStream input, String encoding)
            throws IOException {
        return toString(input, Charsets.toCharset(encoding));
}

I think it depends on how you installed python. Note that you can have multiple installs of python, I do on my machine. However, if you install via an msi of a version of python 2.2 or above, I believe it creates a registry key like so:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Python.exe

which gives this value on my machine:

C:\Python25\Python.exe

You just read the registry key to get the location.

However, you can install python via an xcopy like model that you can have in an arbitrary place, and you just have to know where it is installed.

The i.contentWindow is null error seems to occur when calling destroy on an editor instance that was tied to a textarea no longer in the DOM.

CKEDITORY.destroy takes a parameter noUpdate.

The APIdoc states:

If the instance is replacing a DOM element, this parameter indicates whether or not to update the element with the instance contents.

So, to avoid the error, either call destroy before removing the textarea element from the DOM, or call destory(true) to avoid trying to update the non-existent DOM element.

if (CKEDITOR.instances['textarea_name']) {
   CKEDITOR.instances['textarea_name'].destroy(true);
}

Eclipse HTML Editor Plugin

I too have struggled with this totally obvious question. It seemed crazy that this wasn't an extremely easy-to-find feature with all the web development happening in Eclipse these days.

I was very turned off by Aptana because of how bloated it is, and the fact that it starts up a local web server (by default on port 8000) everytime you start Eclipse and you can't disable this functionality. Adobe's port of JSEclipse is now a 400Mb plugin, which is equally insane.

However, I just found a super-lightweight JavaScript editor called Eclipse HTML Editor Plugin, made by Amateras, which was exactly what I was looking for.

If you're doing this with more than one module and want to have more control over versions, you should look into having your own private npm registry.

This way you can npm publish your modules to your private npm registry and use package.json entries the same way you would for public modules.

https://docs.npmjs.com/files/package.json#dependencies

1. dig somedomain.com soa
2. dig @ns.SOA.com somedomain.com axfr

You need to capture from regex. search for the pattern, if found, retrieve the string using group(index). Assuming valid checks are performed:

>>> p = re.compile("name (.*) is valid")
>>> result = p.search(s)
>>> result
<_sre.SRE_Match object at 0x10555e738>
>>> result.group(1)     # group(1) will return the 1st capture (stuff within the brackets).
                        # group(0) will returned the entire matched text.
'my_user_name'

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.

To position an element, a <table> in your case you want to use either padding or margins.

the difference between margins and paddings can be seen as the "box model":

Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.

I highly recommend the article above if you need to learn how to use CSS.

To move the table down and right I would use margins like so:

table{
    margin:25px 0 0 25px;
}

This is in shorthand so the margins are as follows:

margin: top right bottom left;

SELECT  DISTINCT *
FROM    people
WHERE   names = 'Smith'
ORDER BY
        names
LIMIT 10

Sounds like it might be a realative uri. I ran into this problem when doing cross-browser Silverlight; on my blog I mentioned a workaround: pass a "context" uri as the first parameter.

If the uri is realtive, the context uri is used to create a full uri. If the uri is absolute, then the context uri is ignored.

EDIT: You need a "scheme" in the uri, e.g., "ftp://" or "http://"

The fastest way I’m aware of to quickly go to paste-insert mode for a one-shot paste is tpope’s unimpaired, which features yo and yO, presumably mnemonics for “you open”. They’re only documented in his vimdoc, as:

A toggle has not been provided for 'paste' because the typical use case of wrapping of a solitary insertion is so wasteful: You toggle twice, but you only paste once (YOPO). Instead, press yo or yO to invoke o or O with 'paste' already set. Leaving insert mode sets 'nopaste' automatically.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

This worked for me like a charm.

JavaScript:

$(function() { //doc ready
    if (!($.browser == "msie" && $.browser.version < 7)) {
        var target = "#floating", top = $(target).offset().top - parseFloat($(target).css("margin-top").replace(/auto/, 0));
        $(window).scroll(function(event) {
            if (top <= $(this).scrollTop()) {
                $(target).addClass("fixed");
            } else {
                $(target).removeClass("fixed");
            }
        });
    }
});

CSS:

#floating.fixed{
    position:fixed;
    top:0;
}

You can use the following command

stat -c "%a %n" *

Also you can use any filename or directoryname instead of * to get a specific result.

On Mac, you can use

stat -f '%A %N' *

Try this out:

grep "Killed process" /var/log/syslog

If you type the executable name and a /? switch at the command line, there is typically help information available. Doing so with taskkill /? provides the following, for instance:

TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]

Description:
    This tool is used to terminate tasks by process id (PID) or image name.

Parameter List:
    /S    system           Specifies the remote system to connect to.

    /U    [domain\]user    Specifies the user context under which the
                           command should execute.

    /P    [password]       Specifies the password for the given user
                           context. Prompts for input if omitted.

    /FI   filter           Applies a filter to select a set of tasks.
                           Allows "*" to be used. ex. imagename eq acme*

    /PID  processid        Specifies the PID of the process to be terminated.
                           Use TaskList to get the PID.

    /IM   imagename        Specifies the image name of the process
                           to be terminated. Wildcard '*' can be used
                           to specify all tasks or image names.

    /T                     Terminates the specified process and any
                           child processes which were started by it.

    /F                     Specifies to forcefully terminate the process(es).

    /?                     Displays this help message.

Filters:
    Filter Name   Valid Operators           Valid Value(s)
    -----------   ---------------           -------------------------
    STATUS        eq, ne                    RUNNING |

    PID           eq, ne, gt, lt, ge, le    PID value
    SESSION       eq, ne, gt, lt, ge, le    Session number.
    CPUTIME       eq, ne, gt, lt, ge, le    CPU time in the format
                                            of hh:mm:ss.
                                            hh - hours,
                                            mm - minutes, ss - seconds
    MEMUSAGE      eq, ne, gt, lt, ge, le    Memory usage in KB
    USERNAME      eq, ne                    User name in [domain\]user

    SERVICES      eq, ne                    Service name
    WINDOWTITLE   eq, ne                    Window title

    NOTE
    ----
    1) Wildcard '*' for /IM switch is accepted only when a filter is applied.
    2) Termination of remote processes will always be done forcefully (/F).
    3) "WINDOWTITLE" and "STATUS" filters are not considered when a remote
       machine is specified.

Examples:
    TASKKILL /IM notepad.exe
    TASKKILL /PID 1230 /PID 1241 /PID 1253 /T
    TASKKILL /F /IM cmd.exe /T 
    TASKKILL /F /FI "PID ge 1000" /FI "WINDOWTITLE ne untitle*"
    TASKKILL /F /FI "USERNAME eq NT AUTHORITY\SYSTEM" /IM notepad.exe
    TASKKILL /S system /U domain\username /FI "USERNAME ne NT*" /IM *
    TASKKILL /S system /U username /P password /FI "IMAGENAME eq note*"

You can also find this information, as well as documentation for most of the other command-line utilities, in the Microsoft TechNet Command-Line Reference

In your comment on @Kenneth's answer you're saying that ReadAsStringAsync() is returning empty string.

That's because you (or something - like model binder) already read the content, so position of internal stream in Request.Content is on the end.

What you can do is this:

public static string GetRequestBody()
{
    var bodyStream = new StreamReader(HttpContext.Current.Request.InputStream);
    bodyStream.BaseStream.Seek(0, SeekOrigin.Begin);
    var bodyText = bodyStream.ReadToEnd();
    return bodyText;
}

You can use GAS, which is gcc's backend assembler:

Had this problem recently in my comp lab. It's simple and Erkan answered it correctly. Just put super("the name of your subclass") So in relation to your problem --> super("ProductionWorker); as the first line of your subclass' constructor.

I found a C preprocessor trick that is doing the same job without declaring a dedicated array string (Source: http://userpage.fu-berlin.de/~ram/pub/pub_jf47ht81Ht/c_preprocessor_applications_en).

Sequential enums

Following the invention of Stefan Ram, sequential enums (without explicitely stating the index, e.g. enum {foo=-1, foo1 = 1}) can be realized like this genius trick:

#include <stdio.h>

#define NAMES C(RED)C(GREEN)C(BLUE)
#define C(x) x,
enum color { NAMES TOP };
#undef C

#define C(x) #x,    
const char * const color_name[] = { NAMES };

This gives the following result:

int main( void )  { 
    printf( "The color is %s.\n", color_name[ RED ]);  
    printf( "There are %d colors.\n", TOP ); 
}

The color is RED.
There are 3 colors.

Non-Sequential enums

Since I wanted to map error codes definitions to are array string, so that I can append the raw error definition to the error code (e.g. "The error is 3 (LC_FT_DEVICE_NOT_OPENED)."), I extended the code in that way that you can easily determine the required index for the respective enum values:

#define LOOPN(n,a) LOOP##n(a)
#define LOOPF ,
#define LOOP2(a) a LOOPF a LOOPF
#define LOOP3(a) a LOOPF a LOOPF a LOOPF
#define LOOP4(a) a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP5(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP6(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP7(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP8(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF
#define LOOP9(a) a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF a LOOPF

This results to the following implementation capabilities:

Very simple solution:

randomize = np.arange(len(x))
np.random.shuffle(randomize)
x = x[randomize]
y = y[randomize]

the two arrays x,y are now both randomly shuffled in the same way

Do not access or modify the collection in the Comparator. The comparator should be used only to determine which object is comes before another. The two objects that are to be compared are supplied as arguments.

Date itself is comparable, so, using generics:

class MovieComparator implements Comparator<Movie> {
    public int compare(Movie m1, Movie m2) {
       //possibly check for nulls to avoid NullPointerException
       return m1.getDate().compareTo(m2.getDate());
    }
}

And do not instantiate the comparator on each sort. Use:

private static final MovieComparator comparator = new MovieComparator();

As with the present java SE 8 release with it's excellent date time API with java.time these kind of calculation can be done more easily instead of using java.util.Calendar and java.util.Date.

• Use date time class's i.e. LocalDateTime of this new API
• Use ZonedDateTime class to handle Time Zone specific calculation including Daylight Saving issues. You will find tutorial and example here.

Now as a sample example for scheduling a task with your use case:

ZonedDateTime now = ZonedDateTime.now(ZoneId.of("America/Los_Angeles"));
ZonedDateTime nextRun = now.withHour(5).withMinute(0).withSecond(0);
if(now.compareTo(nextRun) > 0)
    nextRun = nextRun.plusDays(1);

Duration duration = Duration.between(now, nextRun);
long initalDelay = duration.getSeconds();

ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);            
scheduler.scheduleAtFixedRate(new MyRunnableTask(),
    initalDelay,
    TimeUnit.DAYS.toSeconds(1),
    TimeUnit.SECONDS);

The initalDelay is computed to ask the scheduler to delay the execution in TimeUnit.SECONDS. Time difference issues with unit milliseconds and below seems to be negligible for this use case. But you can still make use of duration.toMillis() and TimeUnit.MILLISECONDS for handling the scheduling computaions in milliseconds.

And also TimerTask is better for this or ScheduledExecutorService?

NO: ScheduledExecutorService seemingly better than TimerTask. StackOverflow has already an answer for you.

From @PaddyD,

You still have the issue whereby you need to restart this twice a year if you want it to run at the right local time. scheduleAtFixedRate won't cut it unless you are happy with the same UTC time all year.

As it is true and @PaddyD already has given a workaround(+1 to him), I am providing a working example with Java8 date time API with ScheduledExecutorService. Using daemon thread is dangerous

class MyTaskExecutor
{
    ScheduledExecutorService executorService = Executors.newScheduledThreadPool(1);
    MyTask myTask;
    volatile boolean isStopIssued;

    public MyTaskExecutor(MyTask myTask$) 
    {
        myTask = myTask$;

    }

    public void startExecutionAt(int targetHour, int targetMin, int targetSec)
    {
        Runnable taskWrapper = new Runnable(){

            @Override
            public void run() 
            {
                myTask.execute();
                startExecutionAt(targetHour, targetMin, targetSec);
            }

        };
        long delay = computeNextDelay(targetHour, targetMin, targetSec);
        executorService.schedule(taskWrapper, delay, TimeUnit.SECONDS);
    }

    private long computeNextDelay(int targetHour, int targetMin, int targetSec) 
    {
        LocalDateTime localNow = LocalDateTime.now();
        ZoneId currentZone = ZoneId.systemDefault();
        ZonedDateTime zonedNow = ZonedDateTime.of(localNow, currentZone);
        ZonedDateTime zonedNextTarget = zonedNow.withHour(targetHour).withMinute(targetMin).withSecond(targetSec);
        if(zonedNow.compareTo(zonedNextTarget) > 0)
            zonedNextTarget = zonedNextTarget.plusDays(1);

        Duration duration = Duration.between(zonedNow, zonedNextTarget);
        return duration.getSeconds();
    }

    public void stop()
    {
        executorService.shutdown();
        try {
            executorService.awaitTermination(1, TimeUnit.DAYS);
        } catch (InterruptedException ex) {
            Logger.getLogger(MyTaskExecutor.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

Note:

• MyTask is an interface with function execute.
• While stopping ScheduledExecutorService, Always use awaitTermination after invoking shutdown on it: There's always a likelihood your task is stuck / deadlocking and the user would wait forever.

The previous example I gave with Calender was just an idea which I did mention, I avoided exact time calculation and Daylight saving issues. Updated the solution on per the complain of @PaddyD

In more recent versions of NERDTree you can use the command :NERDTreeFocus, which will move focus to the NERDTree window.

The easy way to revert a group of commits on shared repository (that people use and you want to preserve the history) is to use git revert in conjunction with git rev-list. The latter one will provide you with a list of commits, the former will do the revert itself.

There are two ways to do that. If you want the revert multiple commits in a single commit use:

for i in `git rev-list <first-commit-sha>^..<last-commit-sha>`; do git revert --no-commit $i; done

this will revert a group of commits you need, but leave all the changes on your working tree, you should commit them all as usual afterward.

Another option is to have a single commit per reverted change:

for i in `git rev-list <first-commit-sha>^..<last-commit-sha>`; do git revert --no-edit -s $i; done

For instance, if you have a commit tree like

 o---o---o---o---o---o--->    
fff eee ddd ccc bbb aaa

to revert the changes from eee to bbb, run

for i in `git rev-list eee^..bbb`; do git revert --no-edit -s $i; done

Here is the snippet worked in my case

final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
    buildAlertMessageNoGps();
}

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

"Inflating" a view means taking the layout XML and parsing it to create the view and viewgroup objects from the elements and their attributes specified within, and then adding the hierarchy of those views and viewgroups to the parent ViewGroup. When you call setContentView(), it attaches the views it creates from reading the XML to the activity. You can also use LayoutInflater to add views to another ViewGroup, which can be a useful tool in a lot of circumstances.

Try using the non-breaking hyphen ‑. I've replaced the dash with that character in your jsfiddle, shrunk the frame down as small as it can go, and the line doesn't split there any more.

I guess anther way, possibly faster, to achieve this is 1) Use dict comprehension to get desired dict (i.e., taking 2nd col of each array) 2) Then use pd.DataFrame to create an instance directly from the dict without loop over each col and concat.

Assuming your mat looks like this (you can ignore this since your mat is loaded from file):

In [135]: mat = {'a': np.random.randint(5, size=(4,2)),
   .....: 'b': np.random.randint(5, size=(4,2))}

In [136]: mat
Out[136]: 
{'a': array([[2, 0],
        [3, 4],
        [0, 1],
        [4, 2]]), 'b': array([[1, 0],
        [1, 1],
        [1, 0],
        [2, 1]])}

Then you can do:

In [137]: df = pd.DataFrame ({name:mat[name][:,1] for name in mat})

In [138]: df
Out[138]: 
   a  b
0  0  0
1  4  1
2  1  0
3  2  1

First, give permission for execution:-
chmod +x script_name

1. If script is not executable:-
   For running sh script file:-
   sh script_name
   For running bash script file:-
   bash script_name
2. If script is executable:-
   ./script_name

NOTE:-you can check if the file is executable or not by using 'ls -a'

You can use jspdf to capture a canvas into an image or pdf like this:

var imgData = canvas.toDataURL('image/png');              
var doc = new jsPDF('p', 'mm');
doc.addImage(imgData, 'PNG', 10, 10);
doc.save('sample-file.pdf');

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";

If Controls.Find is not found "textBox1" => error. You must add code.

If(tbx != null)

Edit:

TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
If(tbx != null)
   tbx.Text = "found!";

Create the following function

CREATE OR REPLACE FUNCTION isnull(text, text) RETURNS text AS 'SELECT (CASE (SELECT $1 "
    "is null) WHEN true THEN $2 ELSE $1 END) AS RESULT' LANGUAGE 'sql'

And it'll work.

You may to create different versions with different parameter types.

You could use input type image.

<input type="image" src="http://example.com/path/to/image.png" />

It works as a button and can have the event handlers attached to it.

Alternatively, you can use css to style your button with a background image, and set the borders, margins and the like appropriately.

<button style="background: url(myimage.png)" ... />

No need for jQuery unless you target old browsers and don't want to use shims.

var yahooOnly = JSON.parse(jsondata).filter(function (entry) {
    return entry.website === 'yahoo';
});

In ES2015:

const yahooOnly = JSON.parse(jsondata).filter(({website}) => website === 'yahoo');

I recommend web storage. Example:

// Storing the data: localStorage.setItem("variableName","Text"); // Receiving the data: localStorage.getItem("variableName");

Just replace variable with your variable name and text with what you want to store. According to W3Schools, it's better than cookies.

I'm not a mod_rewrite expert, I often struggle with it, but I have done this on one of my sites, it might need other flags etc depending on your circumstances. I'm using this:

RewriteEngine on

RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$
RewriteCond %{REQUEST_URI} !^/subdomains/subdomain
RewriteRule ^(.*)$ /subdomains/subdomain/$1 [L] 

Any other rewrite rules for the rest of the site must go afterwards to prevent them from interfering with your subdomain rewrites.

None of the css trick worked for me (in my case the fb-like box was pulled right with "float:right"). However, what worked without any additional tricks is an IFRAME version of the button code. I.e.:

<iframe src="//www.facebook.com/plugins/like.php?href=..." 
        scrolling="no" frameborder="0" 
        style="border:none; overflow:hidden; width:71px; height:21px;" 
        allowTransparency="true">
</iframe>

(Note custom width in style, and no need to include additional javascript.)

Use .unshift() to add to the beginning of an array.

TheArray.unshift(TheNewObject);

See MDN for doc on unshift() and here for doc on other array methods.

FYI, just like there's .push() and .pop() for the end of the array, there's .shift() and .unshift() for the beginning of the array.

i had same issue i resolve this use under

go to gmail.com

my account

and enable

Allow less secure apps: ON

it start works

I've used

die() {
        echo $1
        kill $$
}

before; i think because 'exit' was failing for me for some reason. The above defaults seem like a good idea, though.

The php.js project has JavaScript implementations of many of PHP's functions. base64_encode and base64_decode are included.

I was injecting service like this:

private messageShowService MessageShowService

instead of:

private messageShowService: MessageShowService

and that was the reason of error, despite nothing related with ',' was there.

Well, there's an alternate way! You can use a button instead of hyperlink. Hence, when the button is clicked the web page specified in "name_of_webpage" is opened in the target frame named "name_of_iframe". It works for me!

<form method="post" action="name_of_webpage" target="name_of_iframe">
<input type="submit" value="any_name_you_want" />
</form>
<iframe name="name_of_iframe"></iframe>

I had similar issue before and in my case the file was in another machine so i have mapped network drive z to the folder location where my file is then i created a context in tomcat so in my web project i could access the HTML file via context

If you are using multiple forms, you can use:

<form name='myForm'>
    <input type='text' name='name' value=''>
</form>

<script type="text/javascript"> 
    document.forms['myForm']['name'].value = "New value";
</script>

With Swift

let commentImageView = UIImageView(frame: CGRectMake(100, 100, 100, 100))
commentImageView.image = UIImage(named: "myimage.png")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
commentImageView.tintColor = UIColor.blackColor()
addSubview(commentImageView)

We can also sort the key by using Arrays.sort method.

Map<String, String> map = new HashMap<String, String>();
Object[] objArr = new Object[map.size()];
for (int i = 0; i < map.size(); i++) {
objArr[i] = map.get(i);
}
Arrays.sort(objArr);
for (Object str : objArr) {
System.out.println(str);
}

Try BufferedReader.readLine() instead of all this complication. It will recognize all possible line terminators.

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

In my case, when using IntelliJ, I had multiple modules in the project. The main module was dependent on another module which had the maven dependencies on Spring.

The main module had Entitys and so did the second module. But when I ran the main module, only the Entitys from the second module got recognized as managed classes.

I then added Spring dependencies on the main module as well, and guess what? It recognized all the Entitys.

The reason your functor example does not work is that you need an instance to invoke the operator().

The way that setuptools does it, it uses the pkg_resources.parse_version function. It should be PEP440 compliant.

Example:

#! /usr/bin/python
# -*- coding: utf-8 -*-
"""Example comparing two PEP440 formatted versions
"""
import pkg_resources

VERSION_A = pkg_resources.parse_version("1.0.1-beta.1")
VERSION_B = pkg_resources.parse_version("v2.67-rc")
VERSION_C = pkg_resources.parse_version("2.67rc")
VERSION_D = pkg_resources.parse_version("2.67rc1")
VERSION_E = pkg_resources.parse_version("1.0.0")

print(VERSION_A)
print(VERSION_B)
print(VERSION_C)
print(VERSION_D)

print(VERSION_A==VERSION_B) #FALSE
print(VERSION_B==VERSION_C) #TRUE
print(VERSION_C==VERSION_D) #FALSE
print(VERSION_A==VERSION_E) #FALSE

The final keyword is used to declare constants.

final int FILE_TYPE = 3;

The finally keyword is used in a try catch statement to specify a block of code to execute regardless of thrown exceptions.

try
{
  //stuff
}
catch(Exception e)
{
  //do stuff
}
finally
{
  //this is always run
}

And finally (haha), finalize im not entirely sure is a keyword, but there is a finalize() function in the Object class.

To find all files modified in the last 24 hours use the one below. The -1 here means changed 1 day or less ago.

find . -mtime -1 -ls

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

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

mysql> INSERT INTO date_test VALUES (NULL);
ERROR 1048 (23000): Column 'pdd' cannot be null
mysql> INSERT INTO date_test VALUES ('NULL');
Query OK, 1 row affected, 1 warning (0.05 sec)

mysql> show warnings;

Remember that window is the global namespace. These two lines attempt to declare the same variable:

window.APP = { ... }
const APP = window.APP

The second definition is not allowed in strict mode (enabled with 'use strict' at the top of your file).

To fix the problem, simply remove the const APP = declaration. The variable will still be accessible, as it belongs to the global namespace.

With Postgres 9.3+, just use the -> operator. For example,

SELECT data->'images'->'thumbnail'->'url' AS thumb FROM instagram;

see http://clarkdave.net/2013/06/what-can-you-do-with-postgresql-and-json/ for some nice examples and a tutorial.

You can also use google-collections (guava) Joiner class if you want to customize the print format

Compare password in laravel and lumen:

This may be possible that bcrypt function does not work with php7 then you can use below code in laravel and lumen as per your requirements:

use Illuminate\Support\Facades\Hash;

$test = app('hash')->make("test");
if (Hash::check('test', $test)) {
   echo "matched";
} else {
   echo "no matched";
}

I hope, this help will make you happy :)

You are not getting value of $id=$_GET['id'];

And you are using it (before it gets initialised).

Use php's in built isset() function to check whether the variable is defied or not.

So, please update the line to:

$id = isset($_GET['id']) ? $_GET['id'] : '';

There are several libraries. Here are two examples:

❐ Apache Commons Lang

Apache Commons Lang includes a special class to escape or unescape strings (CSV, EcmaScript, HTML, Java, Json, XML): org.apache.commons.lang3.StringEscapeUtils.

• Escape to CSV

  String escaped = StringEscapeUtils
      .escapeCsv("I said \"Hey, I am 5'10\".\""); // I said "Hey, I am 5'10"."
  
  System.out.println(escaped); // "I said ""Hey, I am 5'10""."""
  

• Unescape from CSV

  String unescaped = StringEscapeUtils
      .unescapeCsv("\"I said \"\"Hey, I am 5'10\"\".\"\"\""); // "I said ""Hey, I am 5'10""."""
  
  System.out.println(unescaped); // I said "Hey, I am 5'10"."
  

_{* You can download it from here.}

❐ OpenCSV

If you use OpenCSV, you will not need to worry about escape or unescape, only for write or read the content.

• Writing file:

  FileOutputStream fos = new FileOutputStream("awesomefile.csv"); 
  OutputStreamWriter osw = new OutputStreamWriter(fos, "UTF-8");
  CSVWriter writer = new CSVWriter(osw);
  ...
  String[] row = {
      "123", 
      "John", 
      "Smith", 
      "39", 
      "I said \"Hey, I am 5'10\".\""
  };
  writer.writeNext(row);
  ...
  writer.close();
  osw.close();
  os.close();
  

• Reading file:

  FileInputStream fis = new FileInputStream("awesomefile.csv"); 
  InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
  CSVReader reader = new CSVReader(isr);
  
  for (String[] row; (row = reader.readNext()) != null;) {
      System.out.println(Arrays.toString(row));
  }
  
  reader.close();
  isr.close();
  fis.close();

Class path entries can contain the basename wildcard character *, which is considered equivalent to specifying a list of all the files in the directory with the extension .jar or .JAR. For example, the class path entry foo/* specifies all JAR files in the directory named foo. A classpath entry consisting simply of * expands to a list of all the jar files in the current directory.

This should work in Java6, not sure about Java5

(If it seems it does not work as expected, try putting quotes. eg: "foo/*")

You need to tell the query what value to pick for the other columns, MIN or MAX seem like suitable choices.

 SELECT
   U.NAME, MIN(P.PIC_ID)
 FROM
   USERS U,
   PICTURES P,
   POSTINGS P1
 WHERE
   U.EMAIL_ID = P1.EMAIL_ID AND
   P1.PIC_ID = P.PIC_ID AND
   P.CAPTION LIKE '%car%'
 GROUP BY
   U.NAME;

import-module Microsoft.Exchange.Management.PowerShell.E2010aTry with some implementation like:

$exchangeser = "MTLServer01"
$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionURI http://${exchangeserver}/powershell/ -Authentication kerberos
import-PSSession $session 

or

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

As suggested this may be an issue with your compiler version.

Try using the following code to convert a long to std::string:

#include <sstream>
#include <string>
#include <iostream>

int main() {
    std::ostringstream ss;
    long num = 123456;
    ss << num;
    std::cout << ss.str() << std::endl;
}

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>

{glue} offers much better string interpolation, see my other answer. Also, as Dainis rightfully mentions, sprintf() is not without problems.

There's also sprintf():

sprintf("Current working dir: %s", wd)

To print to the console output, use cat() or message():

cat(sprintf("Current working dir: %s\n", wd))
message(sprintf("Current working dir: %s\n", wd))

You need to run

git fetch

To get all changes and then you will not receive message with "your branch is ahead".

I've created an open source (BSD) C header that deals with this problem. It currently supports POSIX and Windows. Please check it out:

https://github.com/cxong/tinydir

tinydir_dir dir;
tinydir_open(&dir, "/path/to/dir");

while (dir.has_next)
{
    tinydir_file file;
    tinydir_readfile(&dir, &file);

    printf("%s", file.name);
    if (file.is_dir)
    {
        printf("/");
    }
    printf("\n");

    tinydir_next(&dir);
}

tinydir_close(&dir);

Add an input id to the element and do something like that:

document.getElementById('inputId').value.split(/[\\$]/).pop()

You can add a class declaration to the submit button of a form by doing the following:

<%= f.submit class: 'btn btn-default' %> <-- Note: there is no comma!

If you are altering a _form.html.erb partial of a scaffold and you want to keep the dynamic change of the button name between controller actions, DO NOT specify a name 'name'.

Without specifying a name and depending on the action the form is rendered the button will get the .class = "btn btn-default" (Bootstrap class)(or whatever .class you specify) with the following names:

• Update model_name

• Create model_name
  (where model_name the name of the scaffold's model)

as @PhilHarvey said, you can use mysqld --verbose --help | grep datadir

The limitation of execl is that when executing a shell command or any other script that is not in the current working directory, then we have to pass the full path of the command or the script. Example:

execl("/bin/ls", "ls", "-la", NULL);

The workaround to passing the full path of the executable is to use the function execlp, that searches for the file (1st argument of execlp) in those directories pointed by PATH:

execlp("ls", "ls", "-la", NULL);

var capitalized = yourstring[0].toUpperCase() + yourstring.substr(1);

If you want to create the popup window through jQuery then you'll need to use a plugin. This one seems like it will do what you want:

http://rip747.github.com/popupwindow/

Alternately, you can always use JavaScript's window.open function.

Note that with either approach, the new window must be opened in response to user input/action (so for instance, a click on a link or button). Otherwise the browser's popup blocker will just block the popup.

In Ubuntu (PHP-FPM,Nginx)

sudo apt-get install php5-mcrypt

After installing php5-mcrypt

you have to make a symlink to ini files in mods-available:

sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/mcrypt.ini

enable:

sudo php5enmod mcrypt

restart php5-fpm:

sudo service php5-fpm restart

More detail

The backslash indicates a special escape character. Therefore, directory = path_to_directory.replace("\", "\\") would cause Python to think that the first argument to replace didn't end until the starting quotation of the second argument since it understood the ending quotation as an escape character.

directory=path_to_directory.replace("\\","\\\\")

May be below code can help:

<button [attr.disabled]="!isValid ? true : null">Submit</button>

I did this in Node JS and it solved this problem:

var data = JSON.parse(Buffer.concat(arr).toString());

The term parameter refers to any declaration within the parentheses following the method/function name in a method/function declaration or definition; the term argument refers to any expression within the parentheses of a method/function call. i.e.

1. parameter used in function/method definition.
2. arguments used in function/method call.

Please have a look at the below example for better understanding:

package com.stackoverflow.works;

public class ArithmeticOperations {

    public static int add(int x, int y) { //x, y are parameters here
        return x + y;
    }

    public static void main(String[] args) {
        int x = 10;
        int y = 20;
        int sum = add(x, y); //x, y are arguments here
        System.out.println("SUM IS: " +sum);
    }

}

Thank you!

You should use a DialogFragment instead.

Here's my version in vanilla JS (tested on Chrome)

works with:

• name="input"
• name="form[name]" (creates an object)
• name="checkbox[]" (creates an object with an array)
• name="form[checkbox][]" (creates an array)
• name="form[select][name]" (creates an object with an object containing only the selected value)

/**
 * Get the values from a form
 * @param formId ( ID without the # )

 */
function getFormValues( formId )

    let postData = {};
    let form = document.forms[formId];
    let formData = new FormData( form );

    for ( const value of formData.entries() )
    {
        let container = postData;
        let key = value[0];
        let arrayKeys = key.match( /\[[\w\-]*\]/g ); // Check for any arrays

        if ( arrayKeys !== null )
        {
            arrayKeys.unshift( key.substr( 0, key.search( /\[/ ) ) );  // prepend the first key to the list
            for ( let i = 0, count = arrayKeys.length, lastRun = count - 1; i < count; i++ )

Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:

str = str.replace(/[^-a-z0-9]+/g, "");

Also, if you need to match upper-case letters along with lower case, you should use:

str = str.replace(/[^-a-zA-Z0-9]+/g, "");

I tried the following and presto changeo, my transparent window was no longer frozen in place but could be moved!! (throw away all those other complex solutions above...)

   private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        base.OnMouseLeftButtonDown(e);
        // Begin dragging the window
        this.DragMove();
    }

In the absence of more detailed info:

using(var dbContext = new dbDataContext())
{
    var data = dbContext.SomeTable.SingleOrDefault(row => row.id == requiredId);
    if(data != null)
    {
        data.SomeField = newValue;
    }
    dbContext.SubmitChanges();
}

Just adding a point to the whole discussion as to why this warning comes up (It wasn't clear to me before). The reason one gets this is as mentioned before is because 'a' in this case is a vector and the inequality 'a>0' produces another vector of TRUE and FALSE (where 'a' is >0 or not).

If you would like to instead test if any value of 'a>0', you can use functions - 'any' or 'all'

Best

Just select the Eclipse version of the keycap in the Keymap settings. An Eclipse Keymap is included in Android Studio.

Simply add the following line in your build.gradle project

dependencies {
    ...
    compile 'com.android.support:cardview-v7:24.0.0'
}

And sync the project with gradle.

It is from duplicated question

$json = '[   
{"product_id":"63","product_batch":"BAtch1","product_quantity":"50","product_price":"200","discount":"0","net_price":"20000"},    
{"product_id":"67","product_batch":"Batch2","product_quantity":"50","product_price":"200","discount":"0","net_price":"20000"}
]';

$array = json_decode($json, true);

$out = array_map(function ($product) {
  return array_merge([
    'price'    => $product['product_price'],
    'quantity' => $product['product_quantity'],
  ], array_flip(array_filter(array_flip($product), function ($value) {
    return $value != 'product_price' && $value != 'product_quantity';
  })));
}, $array);

var_dump($out);

I got this same error working in Eclipse with Maven with the additional information

schema_reference.4: Failed to read schema document 'https://maven.apache.org/xsd/maven-4.0.0.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

This was after copying in a new controller and it's interface from a Thymeleaf example. Honestly, no matter how careful I am I still am at a loss to understand how one is expected to figure this out. On a (lucky) guess I right clicked the project, clicked Maven and Update Project which cleared up the issue.

For DEFAULT CURRENT_TIMESTAMP:

ALTER TABLE tablename
 CHANGE COLUMN columnname1 columname1 DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
 CHANGE COLUMN columnname2 columname2 DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP;

Please note double columnname declaration

Removing DEFAULT CURRENT_TIMESTAMP:

ALTER TABLE tablename
 ALTER COLUMN columnname1 DROP DEFAULT,
 ALTER COLUMN columnname2 DROPT DEFAULT;

try qsort in stdlib.h.

You can try using constructor.name.

[].constructor.name
new RegExp().constructor.name

As with everything JavaScript, someone will eventually invariably point that this is somehow evil, so here is a link to an answer that covers this pretty well.

An alternative is to use Object.prototype.toString.call

Object.prototype.toString.call([])
Object.prototype.toString.call(/./)

You could use a string stream and read the elements into the vector.

Here are many different examples...

A copy of one of the examples:

std::vector<std::string> split(const std::string& s, char seperator)
{
   std::vector<std::string> output;

    std::string::size_type prev_pos = 0, pos = 0;

    while((pos = s.find(seperator, pos)) != std::string::npos)
    {
        std::string substring( s.substr(prev_pos, pos-prev_pos) );

        output.push_back(substring);

        prev_pos = ++pos;
    }

    output.push_back(s.substr(prev_pos, pos-prev_pos)); // Last word

    return output;
}

Minimal solution that worked for me for current project

• A create-react-app project
• Ubuntu / *nix
• 2020
• Node 14.7

delete node_modules/browserslist directory in the project

now

npm run build

no longer generates that message

Sample Code:

ListView list = (ListView) findViewById(R.id.listview);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
      Object listItem = list.getItemAtPosition(position);
   } 
});

In the sample code above, the listItem should contain the selected data for the textView.

I had the same issue on windows 10, after trying all the previous solution the problem persists so I decided to uninstall my python 2.7 and install the version 2.7.13 and it works perfectly.

This is my edited version : you just need to add an extra argument "autoClose".

example :

 $('input[name="fieldName"]').datepicker({ autoClose: true});

also you can specify a close callback if you want. :)

replace datepicker.js with this:

!function( $ ) {

// Picker object

var Datepicker = function(element, options , closeCallBack){
    this.element = $(element);
    this.format = DPGlobal.parseFormat(options.format||this.element.data('date-format')||'dd/mm/yyyy');
    this.autoClose = options.autoClose||this.element.data('date-autoClose')|| true;
    this.closeCallback = closeCallBack || function(){};

Each java.util.List implementation is required to preserve the order so either you are using ArrayList, LinkedList, Vector, etc. each of them are ordered collections and each of them preserve the order of insertion (see http://download.oracle.com/javase/1.4.2/docs/api/java/util/List.html)

var mystring = "this,is,a,test"
mystring.replace(/,/g, "newchar");

Django querysets are lazy. That means a query will hit the database only when you specifically ask for the result.

So until you print or actually use the result of a query you can filter further with no database access.

As you can see below your code only executes one sql query to fetch only the last 10 items.

In [19]: import logging                                 
In [20]: l = logging.getLogger('django.db.backends')    
In [21]: l.setLevel(logging.DEBUG)                      
In [22]: l.addHandler(logging.StreamHandler())      
In [23]: User.objects.all().order_by('-id')[:10]          
(0.000) SELECT "auth_user"."id", "auth_user"."username", "auth_user"."first_name", "auth_user"."last_name", "auth_user"."email", "auth_user"."password", "auth_user"."is_staff", "auth_user"."is_active", "auth_user"."is_superuser", "auth_user"."last_login", "auth_user"."date_joined" FROM "auth_user" ORDER BY "auth_user"."id" DESC LIMIT 10; args=()
Out[23]: [<User: hamdi>]

SELECT owner, table_name
  FROM dba_constraints
 WHERE constraint_name = <<your constraint name>>

will give you the name of the table. If you don't have access to the DBA_CONSTRAINTS view, ALL_CONSTRAINTS or USER_CONSTRAINTS should work as well.

Create a .bashrc file under ~/.bashrc and away you go. Similarly for ~/.gitconfig.

~ is usually your C:\Users\<your user name> folder. Typing echo ~ in the Git Bash terminal will tell you what that folder is.

If you can't create the file (e.g. running Windows), run the below command:

copy > ~/.bashrc

The window will output an error message (command not found), but the file will be created and ready for you to edit.

Try this

Using UNION

$sql = '';
$count = 0;
foreach($search as $text)
{
  if($count > 0)
     $sql = $sql."UNION Select name From myTable WHERE Name LIKE '%$text%'";
  else
     $sql = $sql."Select name From myTable WHERE Name LIKE '%$text%'";

  $count++;
}

Using WHERE IN

$comma_separated = "('" . implode("','", $search) . "')";  // ('1','2','3')
$sql = "Select name From myTable WHERE name IN ".$comma_separated ;

In python, A dynamic array is an 'array' from the array module. E.g.

from array import array
x = array('d')          #'d' denotes an array of type double
x.append(1.1)
x.append(2.2)
x.pop()                 # returns 2.2

This datatype is essentially a cross between the built-in 'list' type and the numpy 'ndarray' type. Like an ndarray, elements in arrays are C types, specified at initialization. They are not pointers to python objects; this may help avoid some misuse and semantic errors, and modestly improves performance.

However, this datatype has essentially the same methods as a python list, barring a few string & file conversion methods. It lacks all the extra numerical functionality of an ndarray.

See https://docs.python.org/2/library/array.html for details.

You don't need jQuery. You can do this using a for loop:

var total = 0;
for (var i = 0; i < someArray.length; i++) {
    total += someArray[i] << 0;
}

To replace the old version with the new one, you need to change the link for it. Type that command to terminal.

brew link --force openssl

Check the version of openssl again. It should be changed.

It is easy to configure it using your system local zone, Just in your application.rb add this

config.time_zone = Time.now.zone

Then, rails should show you timestamps in your localtime or you can use something like this instruction to get the localtime

Post.created_at.localtime

Instead of detecting the keyboard, try to detect the size of the window

If the height of the window was reduced, and the width is still the same, it means that the keyboard is on. Else the keyboard is off, you can also add to that, test if any input field is on focus or not.

Try this code for example.

var last_h = $(window).height(); //  store the intial height.
var last_w = $(window).width(); //  store the intial width.
var keyboard_is_on = false;
$(window).resize(function () {
    if ($("input").is(":focus")) {
        keyboard_is_on =
               ((last_w == $(window).width()) && (last_h > $(window).height()));
    }   
});     

The problem is that these two queries are each returning more than one row:

select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close')
select isbn from dbo.lending where lended_date between @fdate and @tdate

You have two choices, depending on your desired outcome. You can either replace the above queries with something that's guaranteed to return a single row (for example, by using SELECT TOP 1), OR you can switch your = to IN and return multiple rows, like this:

select * from dbo.books where isbn IN (select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close'))

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

This used to work because I used it to create custom Google searches with my own options. Google made changes on their end and broke my private customized search page :( No longer working sample below. It was very useful for complex search patterns.

I guess the better option is to just use Curl or similar.

Another late answer... Here's how Microsoft uses it in their wchar.h. Notice they also disable Warning C6386:

__inline _CRT_INSECURE_DEPRECATE_MEMORY(wmemcpy_s) wchar_t * __CRTDECL
wmemcpy(_Out_opt_cap_(_N) wchar_t *_S1, _In_opt_count_(_N) const wchar_t *_S2, _In_ size_t _N)
{
    #pragma warning( push )
    #pragma warning( disable : 4996 6386 )
        return (wchar_t *)memcpy(_S1, _S2, _N*sizeof(wchar_t));
    #pragma warning( pop )
} 

Another (!) issue to worry about is the possible change of implementation between early/late versions of Java. I don't believe the implementation details are set in stone, and so potentially an upgrade to a future Java version could cause problems.

Bottom line is, I wouldn't rely on the implementation of hashCode().

Perhaps you can highlight what problem you're actually trying to solve by using this mechanism, and that will highlight a more suitable approach.

If you're using ASP.NET web forms, make sure that you are using the right theme:

I just spent about an hour trying to solve this!

The long must be at least the same size as an int, and possibly, but not necessarily, longer.

On common 32-bit systems, both int and long are 4-bytes/32-bits, and this is valid according to the C++ spec.

On other systems, both int and long long may be a different size. I used to work on a platform where int was 2-bytes, and long was 4-bytes.

I uninstalled all parts of SQL Server 2012 using Control Panel in Windows and then reinstalled (choosing "All Features"). Now it works!

SerialPort (RS-232 Serial COM Port) in C# .NET
This article explains how to use the SerialPort class in .NET to read and write data, determine what serial ports are available on your machine, and how to send files. It even covers the pin assignments on the port itself.

Example Code:

using System;
using System.IO.Ports;
using System.Windows.Forms;

namespace SerialPortExample
{
  class SerialPortProgram
  {
    // Create the serial port with basic settings
    private SerialPort port = new SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One);

    [STAThread]
    static void Main(string[] args)
    { 
      // Instatiate this class
      new SerialPortProgram();
    }

    private SerialPortProgram()
    {
      Console.WriteLine("Incoming Data:");

      // Attach a method to be called when there
      // is data waiting in the port's buffer
      port.DataReceived += new 
        SerialDataReceivedEventHandler(port_DataReceived);

      // Begin communications
      port.Open();

      // Enter an application loop to keep this thread alive
      Application.Run();
    }

    private void port_DataReceived(object sender,
      SerialDataReceivedEventArgs e)
    {
      // Show all the incoming data in the port's buffer
      Console.WriteLine(port.ReadExisting());
    }
  }
}

It's not like that. ArrayList just uses array as internal respentation. If you add more then 60 elements then underlaying array will be exapanded. How ever you can add as much elements to this array as much RAM you have.

I've done it like so:

((ViewManager)entry.getParent()).removeView(entry);

It's AddHeader, not AppendHeader.

<%@ Language=VBScript %>
<%  Option Explicit

Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader "Content-Disposition", "attachment; filename=excelTest.xls"
%>
<table>
    <tr>
        <td>Test</td>
    </tr>
</table>

Stephen Taub has implemented a solution to this question, see Building Async Coordination Primitives, Part 7: AsyncReaderWriterLock.

Stephen Taub is highly regarded in the industry, so anything he writes is likely to be solid.

I won't reproduce the code that he posted on his blog, but I will show you how to use it:

/// <summary>
///     Demo class for reader/writer lock that supports async/await.
///     For source, see Stephen Taub's brilliant article, "Building Async Coordination
///     Primitives, Part 7: AsyncReaderWriterLock".
/// </summary>
public class AsyncReaderWriterLockDemo
{
    private readonly IAsyncReaderWriterLock _lock = new AsyncReaderWriterLock(); 

    public async void DemoCode()
    {           
        using(var releaser = await _lock.ReaderLockAsync()) 
        { 
            // Insert reads here.
            // Multiple readers can access the lock simultaneously.
        }

        using (var releaser = await _lock.WriterLockAsync())
        {
            // Insert writes here.
            // If a writer is in progress, then readers are blocked.
        }
    }
}

If you want a method that's baked into the .NET framework, use SemaphoreSlim.WaitAsync instead. You won't get a reader/writer lock, but you will get tried and tested implementation.

if ( ( param & karen ) == karen )
{
  // Do stuff
}

The bitwise 'and' will mask out everything except the bit that "represents" Karen. As long as each person is represented by a single bit position, you could check multiple people with a simple:

if ( ( param & karen ) == karen )
{
  // Do Karen's stuff
}
if ( ( param & bob ) == bob )
  // Do Bob's stuff
}

$('#abc span').html('A new text for the span.');

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

Also, bear in mind that if you need to export multiple functions at once, like actions you can use

export * from './XThingActions';

var matches = [];
$(".className:checked").each(function() {
    matches.push(this.value);
});

var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'

Use this method to set margin in dp

private void setMargins (View view, int left, int top, int right, int bottom) {
    if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();

        final float scale = getBaseContext().getResources().getDisplayMetrics().density;
        // convert the DP into pixel
        int l =  (int)(left * scale + 0.5f);
        int r =  (int)(right * scale + 0.5f);
        int t =  (int)(top * scale + 0.5f);
        int b =  (int)(bottom * scale + 0.5f);

        p.setMargins(l, t, r, b);
        view.requestLayout();
    }
}

call the method :

setMargins(linearLayout,5,0,5,0);

Is declaring a variable as private static varName; any different from declaring a variable private varName;?

Yes, both are different. And the first one is called class variable because it holds single value for that class whereas the other one is called instance variable because it can hold different value for different instances(Objects). The first one is created only once in jvm and other one is created once per instance i.e if you have 10 instances then you will have 10 different private varName; in jvm.

Does declaring the variable as static give it other special properties?

Yes, static variables gets some different properties than normal instance variables. I've mentioned few already and let's see some here: class variables (instance variables which are declared as static) can be accessed directly by using class name like ClassName.varName. And any object of that class can access and modify its value unlike instance variables are accessed by only its respective objects. Class variables can be used in static methods.

What is the use of a private static variable in Java?

Logically, private static variable is no different from public static variable rather the first one gives you more control. IMO, you can literally replace public static variable by private static variable with help of public static getter and setter methods.

One widely used area of private static variable is in implementation of simple Singleton pattern where you will have only single instance of that class in whole world. Here static identifier plays crucial role to make that single instance is accessible by outside world(Of course public static getter method also plays main role).

public class Singleton {
    private static Singleton singletonInstance = new Singleton();

    private Singleton(){}

    public static Singleton getInstance(){
        return Singleton.singletonInstance;
    }
}

I'd start by using one of the projects out there for Java and CUDA: http://www.jcuda.org/

Changing the address's port number (localhost:) worked for me :)

Try this:

select songName from t
where personName in ('Ryan', 'Holly')
group by songName
having count(distinct personName) = 2

The number in the having should match the amount of people. If you also need the Status to be Complete use this where clause instead of the previous one:

where personName in ('Ryan', 'Holly') and status = 'Complete'

I can't post comments so I have to put this in a separate answer, but it's related to the accepted answer by Shah.

I initially followed Shahs answer (thank you!) by re configuring the OPTIONSVerbHandler in IIS, but my settings were restored when I redeployed my application.

I ended up removing the OPTIONSVerbHandler in my Web.config instead.

<handlers>
    <remove name="OPTIONSVerbHandler"/>
</handlers>

ad 1. It does not implement its methods.

ad 4. The purpose of one interface extending, not implementing another, is to build a more specific interface. For example, SortedMap is an interface that extends Map. A client not interested in the sorting aspect can code against Map and handle all the instances of for example TreeMap, which implements SortedMap. At the same time, another client interested in the sorted aspect can use those same instances through the SortedMap interface.

In your example you are repeating the methods from the superinterface. While legal, it's unnecessary and doesn't change anything in the end result. The compiled code will be exactly the same whether these methods are there or not. Whatever Eclipse's hover says is irrelevant to the basic truth that an interface does not implement anything.

just wanted to leave my .scss example here, I think its kinda best practice, especially I think if you do customization its nice to set the width only once! It is not clever to apply it everywhere, you will increase the human factor exponentially.

Im looking forward for your feedback!

// Set your parameters
$widthSmall: 768px;
$widthMedium: 992px;

// Prepare your "function"
@mixin in-between {
     @media (min-width:$widthSmall) and (max-width:$widthMedium) {
        @content;
     }
}


// Apply your "function"
main {
   @include in-between {
      //Do something between two media queries
      padding-bottom: 20px;
   }
}

FOR NEOVIM

Due to problems with interactive calls (https://github.com/neovim/neovim/issues/1716), I am using this for neovim, based on Dr Beco's answer:

cnoremap w!! execute 'silent! write !SUDO_ASKPASS=`which ssh-askpass` sudo tee % >/dev/null' <bar> edit!

This will open a dialog using ssh-askpass asking for the sudo password.

It's a block of code which is executed when the class gets loaded by a classloader. It is meant to do initialization of static members of the class.

It is also possible to write non-static initializers, which look even stranger:

public class Foo {
    {
        // This code will be executed before every constructor
        // but after the call to super()
    }

    Foo() {

    }
}

On my install, FontProperties only changes the text size, but it's still too large and spaced out. I found a parameter in pyplot.rcParams: legend.labelspacing, which I'm guessing is set to a fraction of the font size. I've changed it with

pyplot.rcParams.update({'legend.labelspacing':0.25})

I'm not sure how to specify it to the pyplot.legend function - passing

prop={'labelspacing':0.25}

or

prop={'legend.labelspacing':0.25}

comes back with an error.

I adopted a SQL 2012 database where I was not a sysadmin but was an administrator on the machine. I used SSMS with "Run as Administrator", added my NT account as a SQL login and set the server role to sysadmin. No problem.

1- update your local meta-data using : git fetch --all

2- show your remote and local branches using : git branch -a , see the following Screenshot

3- switch to target branch , that you want to linked with the remote: using

git checkout branchName

example :

4- Link your local branch to a remote branch using:

git branch --set-upstream-to nameOfRemoteBranch

N.B : nameOfRemoteBranch : to copy from the output of step 2 " git branch -r "

Example of use:

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

The simplest solution would be to use Pillow lib:

from PIL import Image

image = Image.fromarray(<your_numpy_array>.astype(np.uint8))

And you can use it as an image.

After having looked at various versions of itoa for gcc, the most flexible version I have found that is capable of handling conversions to binary, decimal and hexadecimal, both positive and negative is the fourth version found at http://www.strudel.org.uk/itoa/. While sprintf/snprintf have advantages, they will not handle negative numbers for anything other than decimal conversion. Since the link above is either off-line or no longer active, I've included their 4th version below:

/**
 * C++ version 0.4 char* style "itoa":
 * Written by Lukás Chmela
 * Released under GPLv3.
 */
char* itoa(int value, char* result, int base) {
    // check that the base if valid
    if (base < 2 || base > 36) { *result = '\0'; return result; }

    char* ptr = result, *ptr1 = result, tmp_char;
    int tmp_value;

    do {
        tmp_value = value;
        value /= base;
        *ptr++ = "zyxwvutsrqponmlkjihgfedcba9876543210123456789abcdefghijklmnopqrstuvwxyz" [35 + (tmp_value - value * base)];
    } while ( value );

    // Apply negative sign
    if (tmp_value < 0) *ptr++ = '-';
    *ptr-- = '\0';
    while(ptr1 < ptr) {
        tmp_char = *ptr;
        *ptr--= *ptr1;
        *ptr1++ = tmp_char;
    }
    return result;
}

Page reload can be done using javascript code. Use either a HTML button and implement it like...

<input type="button" value="Reload Page" onClick="document.location.reload(true)">

Maven always checks your local repository first, however,your dependency needs to be installed in your repo for maven to find it.

Run mvn install in your dependency module first, and then build your dependent module.

For me the solution was fixing a syntax error:

removing a unwanted semi colon in the angular.module function

I guess you should use in your button

<a data-toggle="modal" href="#form-content"    

instead of href there should be data-target

<a data-toggle="modal" data-target="#form-content"    

just be sure, that modal content is already loaded

I think problem is, that showing modal is called twice, one in ajax call, that works fine, you said modal is shown correctly, but error probably comes with init action on that button, that should handle modal, this action cant be executed, because modal is not loaded at that time.

You can always use

header('Location: https://www.domain.com/cart_save/');

to redirect to the save URL.

But I would recommend to do it by .htaccess and the Apache rewrite rules.

Firefox 64 adds support for the spec draft CSS Scrollbars Module Level 1, which adds two new properties of scrollbar-width and scrollbar-color which give some control over how scrollbars are displayed.

You can set scrollbar-color to one of the following values (descriptions from MDN):

• auto Default platform rendering for the track portion of the scrollbar, in the absence of any other related scrollbar color properties.
• dark Show a dark scrollbar, which can be either a dark variant of scrollbar provided by the platform, or a custom scrollbar with dark colors.
• light Show a light scrollbar, which can be either a light variant of scrollbar provided by the platform, or a custom scrollbar with light colors.
• <color> <color> Applies the first color to the scrollbar thumb, the second to the scrollbar track.

Note that dark and light values are not currently implemented in Firefox.

macOS notes:

The auto-hiding semi-transparent scrollbars that are the macOS default cannot be colored with this rule (they still choose their own contrasting color based on the background). Only the permanently showing scrollbars (System Preferences > Show Scroll Bars > Always) are colored.

Visual Demo:

.scroll {_x000D_
  width: 20%;_x000D_
  height: 100px;_x000D_
  border: 1px solid grey;_x000D_

<p>colors</p><p>colors</p><p>colors</p><p>colors</p><p>colors</p><p>colors</p>_x000D_
</div>

You can set scrollbar-width to one of the following values (descriptions from MDN):

• auto The default scrollbar width for the platform.
• thin A thin scrollbar width variant on platforms that provide that option, or a thinner scrollbar than the default platform scrollbar width.
• none No scrollbar shown, however the element will still be scrollable.

You can also set a specific length value, according to the spec. Both thin and a specific length may not do anything on all platforms, and what exactly it does is platform-specific. In particular, Firefox doesn't appear to be currently support a specific length value (this comment on their bug tracker seems to confirm this). The thin keywork does appear to be well-supported however, with macOS and Windows support at-least.

It's probably worth noting that the length value option and the entire scrollbar-width property are being considered for removal in a future draft, and if that happens this particular property may be removed from Firefox in a future version.

.scroll {_x000D_
  width: 30%;_x000D_
  height: 100px;_x000D_
  border: 1px solid grey;_x000D_

This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.

Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;

byte[] bytes = reportViewer.LocalReport.Render(
    "PDF", null, out mimeType, out encoding, out filenameExtension,
    out streamids, out warnings);

using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
{
    fs.Write(bytes, 0, bytes.Length);
}

Swift 4

Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(self.updateTime), userInfo: nil, repeats: true)

Update function

@objc func updateTime(){
    debugPrint("jalan")
}

Just right click on that column and select properties and write getdate()in Default value or binding.like image:

If you want do it in CodeFirst in EF you should add this attributes befor of your column definition:

[Databasegenerated(Databaseoption.computed)]

this attributes can found in System.ComponentModel.Dataannotion.Schema.

In my opinion first one is better:))

For those of us who did not see -1 by Michal Chaniewski, the complete line of code:

cmd.Parameters.Add("@blah",SqlDbType.VarChar,-1).Value = "some large text";

Anywhere in one compilation unit (usually a .cpp file) would do:

foo.h

class foo {
    static const string s; // Can never be initialized here.
    static const char* cs; // Same with C strings.

    static const int i = 3; // Integral types can be initialized here (*)...
    static const int j; //     ... OR in cpp.
};

foo.cpp

#include "foo.h"
const string foo::s = "foo string";
const char* foo::cs = "foo C string";
// No definition for i. (*)
const int foo::j = 4;

(*) According to the standards you must define i outside of the class definition (like j is) if it is used in code other than just integral constant expressions. See David's comment below for details.

May be will be useful. Just all queries send via ws to node

<VirtualHost *:80>
  ServerName www.domain2.com

  <Location "/">
    ProxyPass "ws://localhost:3001/"
  </Location>
</VirtualHost>

I thought I'd do a comparison of Martijn's answer and svick's answer...

The following program returns the following results:

Testing with exception: 2430985 ticks
Testing with reflection: 155570 ticks

void Main()
{
    var random = new Random(Environment.TickCount);

    dynamic test = new Test();

    var sw = new Stopwatch();

    sw.Start();

    for (int i = 0; i < 100000; i++)
    {
        TestWithException(test, FlipCoin(random));
    }

    sw.Stop();

    Console.WriteLine("Testing with exception: " + sw.ElapsedTicks.ToString() + " ticks");

    sw.Restart();

    for (int i = 0; i < 100000; i++)
    {
        TestWithReflection(test, FlipCoin(random));
    }

    sw.Stop();

    Console.WriteLine("Testing with reflection: " + sw.ElapsedTicks.ToString() + " ticks");
}

class Test
{
    public bool Exists { get { return true; } }
}

bool FlipCoin(Random random)
{
    return random.Next(2) == 0;
}

bool TestWithException(dynamic d, bool useExisting)
{
    try
    {
        bool result = useExisting ? d.Exists : d.DoesntExist;
        return true;
    }
    catch (Exception)
    {
        return false;
    }
}

bool TestWithReflection(dynamic d, bool useExisting)
{
    Type type = d.GetType();

    return type.GetProperties().Any(p => p.Name.Equals(useExisting ? "Exists" : "DoesntExist"));
}

As a result I'd suggest using reflection. See below.

Responding to bland's comment:

Ratios are reflection:exception ticks for 100000 iterations:

Fails 1/1: - 1:43 ticks
Fails 1/2: - 1:22 ticks
Fails 1/3: - 1:14 ticks
Fails 1/5: - 1:9 ticks
Fails 1/7: - 1:7 ticks
Fails 1/13: - 1:4 ticks
Fails 1/17: - 1:3 ticks
Fails 1/23: - 1:2 ticks
...
Fails 1/43: - 1:2 ticks
Fails 1/47: - 1:1 ticks

...fair enough - if you expect it to fail with a probability with less than ~1/47, then go for exception.

The above assumes that you're running GetProperties() each time. You may be able to speed up the process by caching the result of GetProperties() for each type in a dictionary or similar. This may help if you're checking against the same set of types over and again.

You can do something like that :

"/installers/services/".replace(/^\/+/g,'').replace(/\/+$/g,'')

This regex is a common way to have the same behaviour of the trim function used in many languages.

A possible implementation of trim function is :

function trim(string, char){
    if(!char) char = ' '; //space by default
    char = char.replace(/([()[{*+.$^\\|?])/g, '\\$1'); //escape char parameter if needed for regex syntax.
    var regex_1 = new RegExp("^" + char + "+", "g");
    var regex_2 = new RegExp(char + "+$", "g");
    return string.replace(regex_1, '').replace(regex_2, '');
}

Which will delete all / at the beginning and the end of the string. It handles cases like ///installers/services///

You can also simply do :

"/installers/".substring(1, string.length-1);

In my case I had to change the <VirtualHost *> back to <VirtualHost *:80> (which is the default on Ubuntu). Otherwise, the port 443 wasn't using SSL and was sending plain HTML back to the browser.

You can check whether this is your case quite easily: just connect to your server http://www.example.com:443. If you see plain HTML, your Apache is not using SSL on port 443 at all, most probably due to a VirtualHost misconfiguration.

Cheers!

Such inexplicable exceptions are often a result of an unclean xib file. Open the xib in xcode, select File's Owner and click on the "Connection Inspector" (upper right arrow), to see all outlets at once. Look for !s which indicates a missing outlet.

You need to use gdb's memory-display commands. The basic one is x, for examine. There's an example on the linked-to page that uses

gdb> x/4xw $sp

to print "four words (w ) of memory above the stack pointer (here, $sp) in hexadecimal (x)". The quotation is slightly paraphrased.

You're correct in that, semantically, ref provides both "in" and "out" functionality, whereas out only provides "out" functionality. There are some things to consider:

1. out requires that the method accepting the parameter MUST, at some point before returning, assign a value to the variable. You find this pattern in some of the key/value data storage classes like Dictionary<K,V>, where you have functions like TryGetValue. This function takes an out parameter that holds what the value will be if retrieved. It wouldn't make sense for the caller to pass a value into this function, so out is used to guarantee that some value will be in the variable after the call, even if it isn't "real" data (in the case of TryGetValue where the key isn't present).
2. out and ref parameters are marshaled differently when dealing with interop code

Also, as an aside, it's important to note that while reference types and value types differ in the nature of their value, every variable in your application points to a location of memory that holds a value, even for reference types. It just happens that, with reference types, the value contained in that location of memory is another memory location. When you pass values to a function (or do any other variable assignment), the value of that variable is copied into the other variable. For value types, that means that the entire content of the type is copied. For reference types, that means that the memory location is copied. Either way, it does create a copy of the data contained in the variable. The only real relevance that this holds deals with assignment semantics; when assigning a variable or passing by value (the default), when a new assignment is made to the original (or new) variable, it does not affect the other variable. In the case of reference types, yes, changes made to the instance are available on both sides, but that's because the actual variable is just a pointer to another memory location; the content of the variable--the memory location--didn't actually change.

Passing with the ref keyword says that both the original variable and the function parameter will actually point to the same memory location. This, again, affects only assignment semantics. If a new value is assigned to one of the variables, then because the other points to the same memory location the new value will be reflected on the other side.
