On Oracle's own Linux (Version 7.7, PRETTY_NAME="Oracle Linux Server 7.7" in /etc/os-release), if you installed the 18.3 client libraries with

sudo yum install oracle-instantclient18.3-basic.x86_64
sudo yum install oracle-instantclient18.3-sqlplus.x86_64

then you need to put the following in your .bash_profile:

export ORACLE_HOME=/usr/lib/oracle/18.3/client64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME

in order to be able to invoke the SQLPlus client, which, incidentally, is called sqlplus64 on this platform.

Recently I had to work on an older project where the solution and all contained projects were targeted to x32 platform. I kept on trying to copy Oracle.DataAccess.dll and all other suggested Oracle files on all the places, but hit the wall every time. Finally the bulb in the head lit up (after 8 hours :)), and asked to check for the installed ODAC assemblies and their platform. I had all the 64-bit (x64) ODAC clients installed already but not the 32 bit ones (x32). Installed the 32-bit ODAC and the problem disappeared.

How to check the version of installed ODAC: Look in folder C:\Windows\assembly. The "Processor Architecture" property will inform the platform of installed ODAC.

Eight hours is a long time for the bulb to light up. No wonder I always have to slog at work :).

None of the links above about lib and lib32 folder worked for me with Oracle Client 11.2.0 But I found this on the OTN community:

As far as inspecting a client install to try to tell if it's 32 bit or 64 bit, you can check the registry, a 32 bit home will be located in HKLM>Software>WOW6432Node>Oracle, whereas a 64 bit home will be in HKLM>Software>Oracle.

It is a security issue, so to fix it simply do the following:

1. Go to the Oracle Client folder.
2. Right Click on the folder.
3. On security Tab, Add "Authenticated Users" and give this account Read & Execute permission.
4. Apply this security for all folders, Subfolders and Files (IMPORTANT).
5. Don't Forget to REBOOT your Machine; if you forgot to do this you will still face the same problem unless you restart your machine.

Just put ojdbc6.jar in class path, so that we can fix CallbaleStatement exception:

oracle.jdbc.driver.T4CPreparedStatement.setBinaryStream(ILjava/io/InputStream;J)V)

in Oracle.

Easiest Way!!!

1. Right click on project and select "Manage NuGet Packages..."
2. Search for Oracle.ManagedDataAccess. Install it.

If you are using Entity Framework and your Visual Studio Version is 2012 or higher,then

3. Again search for Oracle.ManagedDataAccess.EntityFramework. Install it.
   
4. Use below name spaces in your .cs file:
   using Oracle.ManagedDataAccess.Client;
   using Oracle.ManagedDataAccess.EntityFramework;

Its done. Now restart your visual studio and build your code.

What do these packages do?
After installing these packages no additional Oracle client software is required to be installed to connect to database.

In practical language terms familiar to most programmers, the usual way to detect Turing completeness is if the language allows or allows the simulation of nested unbounded while statements (as opposed to Pascal-style for statements, with fixed upper bounds).

Also DevExpress have Charts (see DevExpress.Com).

You are looking for wctomb(): it's in the ANSI standard, so you can count on it. It works even when the wchar_t uses a code above 255. You almost certainly do not want to use it.

wchar_t is an integral type, so your compiler won't complain if you actually do:

char x = (char)wc;

but because it's an integral type, there's absolutely no reason to do this. If you accidentally read Herbert Schildt's C: The Complete Reference, or any C book based on it, then you're completely and grossly misinformed. Characters should be of type int or better. That means you should be writing this:

int x = getchar();

and not this:

char x = getchar(); /* <- WRONG! */

As far as integral types go, char is worthless. You shouldn't make functions that take parameters of type char, and you should not create temporary variables of type char, and the same advice goes for wchar_t as well.

char* may be a convenient typedef for a character string, but it is a novice mistake to think of this as an "array of characters" or a "pointer to an array of characters" - despite what the cdecl tool says. Treating it as an actual array of characters with nonsense like this:

for(int i = 0; s[i]; ++i) {
  wchar_t wc = s[i];
  char c = doit(wc);
  out[i] = c;
}

is absurdly wrong. It will not do what you want; it will break in subtle and serious ways, behave differently on different platforms, and you will most certainly confuse the hell out of your users. If you see this, you are trying to reimplement wctombs() which is part of ANSI C already, but it's still wrong.

You're really looking for iconv(), which converts a character string from one encoding (even if it's packed into a wchar_t array), into a character string of another encoding.

Now go read this, to learn what's wrong with iconv.

Simply wrap the content using RecyclerView with the Grid Layout

Image: Recycler as GridView layout

Just use the GridLayoutManager like this:

RecyclerView.LayoutManager mRecyclerGrid=new GridLayoutManager(this,3,LinearLayoutManager.VERTICAL,false);
mRecyclerView.setLayoutManager(mRecyclerGrid);

You can set how many items should appear on a row (replace the 3).

I hope this is what you may want to find in the classical CLRS(page 66):

You want to use /* instead of * or */ in most cases

Using * is valid, but it works recursively. It won't look into directories from then on out. People recommend using !*/ to whitelist directories again, but it's actually better to blacklist the highest level folder with /*

# Blacklist files/folders in same directory as the .gitignore file
/*

# Whitelist some files
!.gitignore
!README.md

# Ignore all files named .DS_Store or ending with .log
**/.DS_Store
**.log

# Whitelist folder/a/b1/ and folder/a/b2/
# trailing "/" is optional for folders, may match file though.
# "/" is NOT optional when followed by a *
!folder/
folder/*
!folder/a/
folder/a/*
!folder/a/b1/
!folder/a/b2/
!folder/a/file.txt

# Adding to the above, this also works...
!/folder/a/deeply
/folder/a/deeply/*
!/folder/a/deeply/nested
/folder/a/deeply/nested/*
!/folder/a/deeply/nested/subfolder

The above code would ignore all files except for .gitignore, README.md, folder/a/file.txt, folder/a/b1/ and folder/a/b2/ and everything contained in those last two folders. (And .DS_Store and *.log files would be ignored in those folders.)

Obviously I could do e.g. !/folder or !/.gitignore too.

        SqlCommand cmd = new SqlCommand("create table Employee (empno int,empname varchar(50),salary money);", cn);

You don't have any error in either of your queries. My guess is the following:

• No records exists between 2013-10-17' and '2013-10-18'
• the records the second query returns you exist after '2013-10-18'

I think this is the easy way to open a URL using this function

You can use a simple for in loop:

for (prop in Obj){
    if (Obj[prop]['dinner'] === 'sushi'){

        // Do stuff with found object. E.g. put it into an array:
        arrFoo.push(Obj[prop]);
    }
}

The following fiddle example puts all objects that contain dinner:sushi into an array:

There are no vertical lines in html that you can use but you can fake one by absolutely positioning a div outside of your container with a top:0; and bottom:0; style.

Try this:

CSS

.vr {
    width:10px;
    background-color:#000;
    position:absolute;
    top:0;
    bottom:0;
    left:150px;
}

HTML

<div class="vr">&nbsp;</div>

You can also do this easily in Pandas, if your data is represented in a Dataframe, as described here:

Lambda is a procedure constructor. You can synthesize programs at run-time, although Python's lambda is not very powerful. Note that few people understand that kind of programming.

var message =/*[[${message}]]*/ 'defaultanyvalue';

I assume you want to remove rows that are all NAs. Then, you can do the following :

data <- rbind(c(1,2,3), c(1, NA, 4), c(4,6,7), c(NA, NA, NA), c(4, 8, NA)) # sample data
data
     [,1] [,2] [,3]
[1,]    1    2    3
[2,]    1   NA    4
[3,]    4    6    7
[4,]   NA   NA   NA
[5,]    4    8   NA

data[rowSums(is.na(data)) != ncol(data),]
     [,1] [,2] [,3]
[1,]    1    2    3
[2,]    1   NA    4
[3,]    4    6    7
[4,]    4    8   NA

If you want to remove rows that have at least one NA, just change the condition :

data[rowSums(is.na(data)) == 0,]
     [,1] [,2] [,3]
[1,]    1    2    3
[2,]    4    6    7

SELECT DATEDIFF(day, '2005-12-31 23:59:59.9999999', '2006-01-01 00:00:00.0000000');

As Chris shows, Linq will work; just use Last() to get a reference to the last one in the enumerable, and as long as you aren't working with that reference then do your normal code, but if you ARE working with that reference then do your extra thing. Its downside is that it will always be O(N)-complexity.

You can instead use Count() (which is O(1) if the IEnumerable is also an ICollection; this is true for most of the common built-in IEnumerables), and hybrid your foreach with a counter:

var i=0;
var count = Model.Results.Count();
foreach (Item result in Model.Results)
{
    if (++i == count) //this is the last item
}

The method you are looking for is .limit.

Returns a new Dataset by taking the first n rows. The difference between this function and head is that head returns an array while limit returns a new Dataset.

Example usage:

df.limit(1000)

I recently had a similar problem and ended up fixing it using a mixture of different solutions.

The first and most simple one was to use two tables, one for the headers and one for the body. This works but the headers and the body columns are not aligned. And, since I wanted to use the auto-size that comes with twitter bootstrap tables I ended up creating a Javascript function that changes the headers when: the body is rendered; the windows is resized; the data in the column changes, etc.

Here is some of the code I used:

        <table class="table table-striped table-hover" style="margin-bottom: 0px;">
        <thead>
            <tr>
                <th data-sort="id">Header 1</i></th>
                <th data-sort="guide">Header 2</th>
                <th data-sort="origin">Header 3</th>
                <th data-sort="supplier">Header 4</th>
            </tr>
        </thead>
    </table>
    <div class="bodycontainer scrollable">
        <table class="table table-hover table-striped table-scrollable">
            <tbody id="rows"></tbody>
        </table>
    </div>

The headers and the body are divided in two separate tables. One of them is inside a DIV with the necessary style to generate the vertical scrollbars. Here is the CSS I used:

.bodycontainer {
  //height: 200px
  width: 100%;
  margin: 0;
}

.table-scrollable {
  margin: 0px;
  padding: 0px;
}

I commented the height here because I a wanted the table to reach the bottom of the page, whatever the page height might be.

The data-sort attributes I used in the headers are also used in every td. This way I could get the width and the padding of every td and the width of the row. Using the data-sort attributes I set using CSS the padding and width of each header accordingly and of the header row which is always bigger since it doesn´t have a scrollbar. Here is the function using coffeescript:

fixHeaders: =>
  for header, i in @headers
    tdpadding = parseInt(@$("td[data-sort=#{header}]").css('padding'))
    tdwidth = parseInt(@$("td[data-sort=#{header}]").css('width'))
    @$("th[data-sort=#{header}]").css('padding', tdpadding)
    @$("th[data-sort=#{header}]").css('width', tdwidth)
    if (i+1) == @headers.length
      trwidth = @$("td[data-sort=#{header}]").parent().css('width')
      @$("th[data-sort=#{header}]").parent().parent().parent().css('width', trwidth)
      @$('.bodycontainer').css('height', window.innerHeight - ($('html').outerHeight() -@$('.bodycontainer').outerHeight() ) ) unless @collection.length == 0

Here I assume that you have an array of the headers called @headers.

It is not pretty but it works. Hope it helps someone.

The extra [ ] on the outside of your second syntax are unnecessary, and possibly confusing. You may use them, but if you must you need to have whitespace between them.

Alternatively:

while [ $stats -gt 300 ] || [ $stats -eq 0 ]

We are currently using mongodb as an file storage service for our collaboration over LAN. Also, projects like trello are using mongodb as their backend datastore. I have used couchdb earlier, but not in production capacity.

Path.GetFileName( Request.Url.AbsolutePath )

As this question is been 7 years before, in the latest version which I am using is numpy version 1.13, and python3, I am doing the same thing with adding a row to a matrix, remember to put a double bracket to the second argument, otherwise, it will raise dimension error.

In here I am adding on matrix A

1 2 3
4 5 6

with a row

7 8 9

same usage in np.r_

A= [[1, 2, 3], [4, 5, 6]]
np.append(A, [[7, 8, 9]], axis=0)

    >> array([[1, 2, 3],
              [4, 5, 6],
              [7, 8, 9]])
#or 
np.r_[A,[[7,8,9]]]

Just to someone's intersted, if you would like to add a column,

array = np.c_[A,np.zeros(#A's row size)]

following what we did before on matrix A, adding a column to it

np.c_[A, [2,8]]

>> array([[1, 2, 3, 2],
          [4, 5, 6, 8]])

I found @AgileZebra's answer (plus @starfry's comment) the most useful, but it sets heads to a scalar. An array is probably more useful:

heads=( "${@:1:$(($# - 1))}" )
tail=${@:${#@}}

Note that this is bash-only.

Using date() and strtotime() from the docs.

$date = "2012-01-05";

$year = date('Y', strtotime($date));

$month = date('F', strtotime($date));

echo $month

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

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

Make the class serializable by implementing the interface java.io.Serializable.

• java.io.Serializable - Marker Interface which does not have any methods in it.
• Purpose of Marker Interface - to tell the ObjectOutputStream that this object is a serializable object.

Both the regex and included files are good methods, and I frequently use those. But another alternative is to use a "named location", which is a useful approach in many situations — especially more complicated ones. The official "If is Evil" page shows essentially the following as a good way to do things:

error_page 418 = @common_location;
location /first/location/ {
    return 418;
}
location /second/location/ {
    return 418;
}
location @common_location {
    # The common configuration...
}

There are advantages and disadvantages to these various approaches. One big advantage to a regex is that you can capture parts of the match and use them to modify the response. Of course, you can usually achieve similar results with the other approaches by either setting a variable in the original block or using map. The downside of the regex approach is that it can get unwieldy if you want to match a variety of locations, plus the low precedence of a regex might just not fit with how you want to match locations — not to mention that there are apparently performance impacts from regexes in some cases.

The main advantage of including files (as far as I can tell) is that it is a little more flexible about exactly what you can include — it doesn't have to be a full location block, for example. But it's also just subjectively a bit clunkier than named locations.

Also note that there is a related solution that you may be able to use in similar situations: nested locations. The idea is that you would start with a very general location, apply some configuration common to several of the possible matches, and then have separate nested locations for the different types of paths that you want to match. For example, it might be useful to do something like this:

location /specialpages/ {
    # some config
    location /specialpages/static/ {
        try_files $uri $uri/ =404;
    }
    location /specialpages/dynamic/ {
        proxy_pass http://127.0.0.1;
    }
}

The idiomatic way to do this with LINQ is to process the collection and return a new collection mapped in the fashion you want. For example, to add a constant to every element, you'd want something like

var newNumbers = oldNumbers.Select(i => i + 8);

Doing this in a functional way instead of mutating the state of your existing collection frequently helps you separate distinct operations in a way that's both easier to read and easier for the compiler to reason about.

If you're in a situation where you actually want to apply an action to every element of a collection (an action with side effects that are unrelated to the actual contents of the collection) that's not really what LINQ is best suited for, although you could fake it with Select (or write your own IEnumerable extension method, as many people have.) It's probably best to stick with a foreach loop in that case.

In .NET Core I changed the onDelete option to ReferencialAction.NoAction

         constraints: table =>
            {
                table.PrimaryKey("PK_Schedule", x => x.Id);
                table.ForeignKey(
                    name: "FK_Schedule_Teams_HomeId",
                    column: x => x.HomeId,
                    principalTable: "Teams",
                    principalColumn: "Id",
                    onDelete: ReferentialAction.NoAction);
                table.ForeignKey(
                    name: "FK_Schedule_Teams_VisitorId",
                    column: x => x.VisitorId,
                    principalTable: "Teams",
                    principalColumn: "Id",
                    onDelete: ReferentialAction.NoAction);
            });

You've answered the question with this statement:

Cron calls this .sh every 2 minutes

Cron does not run in a terminal, so why would you expect one to be set?

The most common reason for getting this error message is because the script attempts to source the user's .profile which does not check that it's running in a terminal before doing something tty related. Workarounds include using a shebang line like:

#!/bin/bash -p

Which causes the sourcing of system-level profile scripts which (one hopes) does not attempt to do anything too silly and will have guards around code that depends on being run from a terminal.

If this is the entirety of the script, then the TERM error is coming from something other than the plain content of the script.

Somewhere the code--either your code or a jQuery plugin--is calling $.browser to get the current browser type.

However, early has year the $.browser function was deprecated. Since then some bugs have been filed against it but because it is deprecated, the jQuery team has decided not to fix them. I've decided not to rely on the function at all.

I don't see any references to $.browser in your code, so the problem probably lies in one of your plugins. To find it, look at the source code for each plugin that you've referenced with a <script> tag.

As for how to fix it: well, it depends on the context. E.g., maybe there's an updated version of the problematic plugin. Or perhaps you can use another plugin that does something similar but doesn't depend on $.browser.

For Visual Studio 2019 (v16.2.4) I was only able to find this file here:

C:\Users\\Documents\IISExpress\config\applicationhost.config

Hope this helps as I wasn't able to find the .vs folder location as mentioned in the above suggestions.

This will work as well:

$array = explode('.', $_FILES['image']['name']);
$extension = end($array);

Update

In Swift we don't have to deal with iOS5 old stuff besides syntax is shorter so everything becomes really simple:

Swift 5

func attributedString(from string: String, nonBoldRange: NSRange?) -> NSAttributedString {
    let fontSize = UIFont.systemFontSize
    let attrs = [
        NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: fontSize),
        NSAttributedString.Key.foregroundColor: UIColor.black
    ]
    let nonBoldAttribute = [
        NSAttributedString.Key.font: UIFont.systemFont(ofSize: fontSize),
    ]
    let attrStr = NSMutableAttributedString(string: string, attributes: attrs)
    if let range = nonBoldRange {
        attrStr.setAttributes(nonBoldAttribute, range: range)
    }
    return attrStr
}

Swift 3

func attributedString(from string: String, nonBoldRange: NSRange?) -> NSAttributedString {
    let fontSize = UIFont.systemFontSize
    let attrs = [
        NSFontAttributeName: UIFont.boldSystemFont(ofSize: fontSize),
        NSForegroundColorAttributeName: UIColor.black
    ]
    let nonBoldAttribute = [
        NSFontAttributeName: UIFont.systemFont(ofSize: fontSize),
    ]
    let attrStr = NSMutableAttributedString(string: string, attributes: attrs)
    if let range = nonBoldRange {
        attrStr.setAttributes(nonBoldAttribute, range: range)
    }
    return attrStr
}

Usage:

let targetString = "Updated 2012/10/14 21:59 PM"
let range = NSMakeRange(7, 12)

let label = UILabel(frame: CGRect(x:0, y:0, width:350, height:44))
label.backgroundColor = UIColor.white
label.attributedText = attributedString(from: targetString, nonBoldRange: range)
label.sizeToFit()

Bonus: Internationalisation

Some people commented about internationalisation. I personally think this is out of scope of this question but for instructional purposes this is how I would do it

// Date we want to show
let date = Date()

// Create the string.
// I don't set the locale because the default locale of the formatter is `NSLocale.current` so it's good for internationalisation :p
let formatter = DateFormatter()
formatter.dateStyle = .medium
formatter.timeStyle = .short
let targetString = String(format: NSLocalizedString("Update %@", comment: "Updated string format"),
                          formatter.string(from: date))

// Find the range of the non-bold part
formatter.timeStyle = .none
let nonBoldRange = targetString.range(of: formatter.string(from: date))

// Convert Range<Int> into NSRange
let nonBoldNSRange: NSRange? = nonBoldRange == nil ?
    nil :
    NSMakeRange(targetString.distance(from: targetString.startIndex, to: nonBoldRange!.lowerBound),
                targetString.distance(from: nonBoldRange!.lowerBound, to: nonBoldRange!.upperBound))

// Now just build the attributed string as before :)
label.attributedText = attributedString(from: targetString,
                                        nonBoldRange: nonBoldNSRange)

Result (Assuming English and Japanese Localizable.strings are available)

Previous answer for iOS6 and later (Objective-C still works):

In iOS6 UILabel, UIButton, UITextView, UITextField, support attributed strings which means we don't need to create CATextLayers as our recipient for attributed strings. Furthermore to make the attributed string we don't need to play with CoreText anymore :) We have new classes in obj-c Foundation.framework like NSParagraphStyle and other constants that will make our life easier. Yay!

So, if we have this string:

NSString *text = @"Updated: 2012/10/14 21:59"

We only need to create the attributed string:

if ([_label respondsToSelector:@selector(setAttributedText:)])
{
    // iOS6 and above : Use NSAttributedStrings

    // Create the attributes
    const CGFloat fontSize = 13;
    NSDictionary *attrs = @{
        NSFontAttributeName:[UIFont boldSystemFontOfSize:fontSize],
        NSForegroundColorAttributeName:[UIColor whiteColor]
    };
    NSDictionary *subAttrs = @{
        NSFontAttributeName:[UIFont systemFontOfSize:fontSize]
    };

    // Range of " 2012/10/14 " is (8,12). Ideally it shouldn't be hardcoded
    // This example is about attributed strings in one label
    // not about internationalisation, so we keep it simple :)
    // For internationalisation example see above code in swift
    const NSRange range = NSMakeRange(8,12);

    // Create the attributed string (text + attributes)
    NSMutableAttributedString *attributedText =
      [[NSMutableAttributedString alloc] initWithString:text
                                             attributes:attrs];
    [attributedText setAttributes:subAttrs range:range];

    // Set it in our UILabel and we are done!
    [_label setAttributedText:attributedText];
} else {
    // iOS5 and below
    // Here we have some options too. The first one is to do something
    // less fancy and show it just as plain text without attributes.
    // The second is to use CoreText and get similar results with a bit
    // more of code. Interested people please look down the old answer.

    // Now I am just being lazy so :p
    [_label setText:text];
}

There is a couple of good introductory blog posts here from guys at invasivecode that explain with more examples uses of NSAttributedString, look for "Introduction to NSAttributedString for iOS 6" and "Attributed strings for iOS using Interface Builder" :)

PS: Above code it should work but it was brain-compiled. I hope it is enough :)

Old Answer for iOS5 and below

Use a CATextLayer with an NSAttributedString ! much lighter and simpler than 2 UILabels. (iOS 3.2 and above)

Example.

Don't forget to add QuartzCore framework (needed for CALayers), and CoreText (needed for the attributed string.)

#import <QuartzCore/QuartzCore.h>
#import <CoreText/CoreText.h>

Below example will add a sublayer to the toolbar of the navigation controller. à la Mail.app in the iPhone. :)

- (void)setRefreshDate:(NSDate *)aDate
{
    [aDate retain];
    [refreshDate release];
    refreshDate = aDate;

    if (refreshDate) {

        /* Create the text for the text layer*/    
        NSDateFormatter *df = [[NSDateFormatter alloc] init];
        [df setDateFormat:@"MM/dd/yyyy hh:mm"];

        NSString *dateString = [df stringFromDate:refreshDate];
        NSString *prefix = NSLocalizedString(@"Updated", nil);
        NSString *text = [NSString stringWithFormat:@"%@: %@",prefix, dateString];
        [df release];

        /* Create the text layer on demand */
        if (!_textLayer) {
            _textLayer = [[CATextLayer alloc] init];
            //_textLayer.font = [UIFont boldSystemFontOfSize:13].fontName; // not needed since `string` property will be an NSAttributedString
            _textLayer.backgroundColor = [UIColor clearColor].CGColor;
            _textLayer.wrapped = NO;
            CALayer *layer = self.navigationController.toolbar.layer; //self is a view controller contained by a navigation controller
            _textLayer.frame = CGRectMake((layer.bounds.size.width-180)/2 + 10, (layer.bounds.size.height-30)/2 + 10, 180, 30);
            _textLayer.contentsScale = [[UIScreen mainScreen] scale]; // looks nice in retina displays too :)
            _textLayer.alignmentMode = kCAAlignmentCenter;
            [layer addSublayer:_textLayer];
        }

        /* Create the attributes (for the attributed string) */
        CGFloat fontSize = 13;
        UIFont *boldFont = [UIFont boldSystemFontOfSize:fontSize];
        CTFontRef ctBoldFont = CTFontCreateWithName((CFStringRef)boldFont.fontName, boldFont.pointSize, NULL);
        UIFont *font = [UIFont systemFontOfSize:13];
        CTFontRef ctFont = CTFontCreateWithName((CFStringRef)font.fontName, font.pointSize, NULL);
        CGColorRef cgColor = [UIColor whiteColor].CGColor;
        NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                    (id)ctBoldFont, (id)kCTFontAttributeName,
                                    cgColor, (id)kCTForegroundColorAttributeName, nil];
        CFRelease(ctBoldFont);
        NSDictionary *subAttributes = [NSDictionary dictionaryWithObjectsAndKeys:(id)ctFont, (id)kCTFontAttributeName, nil];
        CFRelease(ctFont);

        /* Create the attributed string (text + attributes) */
        NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:text attributes:attributes];
        [attrStr addAttributes:subAttributes range:NSMakeRange(prefix.length, 12)]; //12 is the length of " MM/dd/yyyy/ "

        /* Set the attributes string in the text layer :) */
        _textLayer.string = attrStr;
        [attrStr release];

        _textLayer.opacity = 1.0;
    } else {
        _textLayer.opacity = 0.0;
        _textLayer.string = nil;
    }
}

In this example I only have two different types of font (bold and normal) but you could also have different font size, different color, italics, underlined, etc. Take a look at NSAttributedString / NSMutableAttributedString and CoreText attributes string keys.

Hope it helps

If you do not need the recording and playback functionality in your app, using off-the-shelf streaming app and player is a reasonable choice.

If you do need them to be in your app, however, you will have to look into MediaRecorder API (for the server/camera app) and MediaPlayer (for client/player app).

Quick sample code for the server:

// this is your network socket
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mCamera = getCameraInstance();
mMediaRecorder = new MediaRecorder();
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// this is the unofficially supported MPEG2TS format, suitable for streaming (Android 3.0+)
mMediaRecorder.setOutputFormat(8);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setOutputFile(pfd.getFileDescriptor());
mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
mMediaRecorder.prepare();
mMediaRecorder.start();

On the player side it is a bit tricky, you could try this:

// this is your network socket, connected to the server
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(pfd.getFileDescriptor());
mMediaPlayer.prepare();
mMediaPlayer.start();

Unfortunately mediaplayer tends to not like this, so you have a couple of options: either (a) save data from socket to file and (after you have a bit of data) play with mediaplayer from file, or (b) make a tiny http proxy that runs locally and can accept mediaplayer's GET request, reply with HTTP headers, and then copy data from the remote server to it. For (a) you would create the mediaplayer with a file path or file url, for (b) give it a http url pointing to your proxy.

As for me, i need the view diraction:

in -> swipe from right

out -> swipe to left

Here works for me code:

slide_in_right.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="50%p" android:toXDelta="0"
            android:duration="@android:integer/config_mediumAnimTime"/>
    <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

slide_out_left.xml

 <set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromXDelta="0" android:toXDelta="-50%p"
                android:duration="@android:integer/config_mediumAnimTime"/>
        <alpha android:fromAlpha="1.0" android:toAlpha="0.0"
                android:duration="@android:integer/config_mediumAnimTime" />
    </set>

transaction code:

inline fun FragmentActivity.setContentFragment(
        containerViewId: Int,
        backStack: Boolean = false,
        isAnimate: Boolean = false,
        f: () -> Fragment

): Fragment? {
    val manager = supportFragmentManager
    return f().apply {
        manager.beginTransaction().let {
            if (isAnimate)
                it.setCustomAnimations(R.anim.slide_in_right, R.anim.slide_out_left)

            if (backStack) {
                it.replace(containerViewId, this, "Fr").addToBackStack("Fr").commit()
            } else {
                it.replace(containerViewId, this, "Fr").commit()
            }
        }
    }
}

If side_effect_func is a function then whatever that function returns is what calls to the mock return. The side_effect_func function is called with the same arguments as the mock. This allows you to vary the return value of the call dynamically, based on the input:

>>> def side_effect_func(value):
...     return value + 1
...
>>> m = MagicMock(side_effect=side_effect_func)
>>> m(1)
2
>>> m(2)
3
>>> m.mock_calls
[call(1), call(2)]

http://www.voidspace.org.uk/python/mock/mock.html#calling

You can use DecimalFormat, but please also note that it is not a good idea to use double in these situations, rather use BigDecimal

Put String in Intent Object

  Intent intent = new Intent(FirstActivity.this,NextAcitivity.class);
  intent.putExtra("key",your_String);
  StartActivity(intent);

NextAcitvity in onCreate method get String

String my_string=getIntent().getStringExtra("key");

that is easy and short method

You could use startOf('day') method to compare just the date

Example :

var dateToCompare = moment("06/04/2015 18:30:00");
var today = moment(new Date());

dateToCompare.startOf('day').isSame(today.startOf('day'));

Straight from the ECMA-262, Fifth Edition ECMAScript Specification:

7.9.1 Rules of Automatic Semicolon Insertion

There are three basic rules of semicolon insertion:

1. When, as the program is parsed from left to right, a token (called the offending token) is encountered that is not allowed by any production of the grammar, then a semicolon is automatically inserted before the offending token if one or more of the following conditions is true:
   • The offending token is separated from the previous token by at least one LineTerminator.
   • The offending token is }.
2. When, as the program is parsed from left to right, the end of the input stream of tokens is encountered and the parser is unable to parse the input token stream as a single complete ECMAScript Program, then a semicolon is automatically inserted at the end of the input stream.
3. When, as the program is parsed from left to right, a token is encountered that is allowed by some production of the grammar, but the production is a restricted production and the token would be the first token for a terminal or nonterminal immediately following the annotation "_{[no LineTerminator here]}" within the restricted production (and therefore such a token is called a restricted token), and the restricted token is separated from the previous token by at least one LineTerminator, then a semicolon is automatically inserted before the restricted token.

However, there is an additional overriding condition on the preceding rules: a semicolon is never inserted automatically if the semicolon would then be parsed as an empty statement or if that semicolon would become one of the two semicolons in the header of a for statement (see 12.6.3).

java.time

Modern answer: use java.time, the modern Java date and time API, for your date and time work. Back in 2011 it was right to use the Timestamp class, but since JDBC 4.2 it is no longer advised.

For your work we need a time zone and a couple of formatters. We may as well declare them static:

static ZoneId zone = ZoneId.of("America/Marigot");
static DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
static DateTimeFormatter timeFormatter = DateTimeFormatter.ofPattern("HH:mm xx");

Now the code could be for example:

    while(resultSet.next()) {
        ZonedDateTime dtStart = resultSet.getObject("dtStart", OffsetDateTime.class)
                 .atZoneSameInstant(zone);

        // I would like to then have the date and time
        // converted into the formats mentioned...
        String dateFormatted = dtStart.format(dateFormatter);
        String timeFormatted = dtStart.format(timeFormatter);
        System.out.format("Date: %s; time: %s%n", dateFormatted, timeFormatted);
    }

Example output (using the time your question was asked):

Date: 09/20/2011; time: 18:13 -0400

In your database timestamp with time zone is recommended for timestamps. If this is what you’ve got, retrieve an OffsetDateTime as I am doing in the code. I am also converting the retrieved value to the user’s time zone before formatting date and time separately. As time zone I supplied America/Marigot as an example, please supply your own. You may also leave out the time zone conversion if you don’t want any, of course.

If the datatype in SQL is a mere timestamp without time zone, retrieve a LocalDateTime instead. For example:

        ZonedDateTime dtStart = resultSet.getObject("dtStart", LocalDateTime.class)
                 .atZone(zone);

No matter the details I trust you to do similarly for dtEnd.

I wasn’t sure what you meant by the xx in HH:MM xx. I just left it in the format pattern string, which yields the UTC offset in hours and minutes without colon.

Link: Oracle tutorial: Date Time explaining how to use java.time.

I just had this issue and was doing exactly as was documented and it still was not working.

Look at your error message and make sure you do not have any special characters copied in. I was getting the error

SyntaxError: illegal character @(shell):1:43

When I went to character 43 it was just the start of my object ID, after the open quotes, exactly as I pasted it in. I put my cursor there and hit backspace nothing appeared to happen when it should have removed the open quote. I hit backspace again and it removed the open quote, then I put the quote back in and executed the query and it worked, despite looking exactly the same.

I was doing development in WebMatrix and copied the object id from the console. Whenever you copy from the console in WebMatrix you're likely to pick up some invisible characters that will cause errors.

Posting parameters Using POST:-

URL url;
URLConnection urlConn;
DataOutputStream printout;
DataInputStream  input;
url = new URL (getCodeBase().toString() + "env.tcgi");
urlConn = url.openConnection();
urlConn.setDoInput (true);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type","application/json");   
urlConn.setRequestProperty("Host", "android.schoolportal.gr");
urlConn.connect();  
//Create JSONObject here
JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");

The part which you missed is in the the following... i.e., as follows..

// Send POST output.
printout = new DataOutputStream(urlConn.getOutputStream ());
printout.writeBytes(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
printout.flush ();
printout.close ();

The rest of the thing you can do it.

As mentioned above, edit the application host.config. An easy way to find this is run your site in VS using IIS Express. Right click the systray icon, show all applications. Choose your site, and then click on the config link at the bottom to open it.

I'd suggest adding another binding entry, and leave the initial localhost one there. This additional binding will appear in the IIS Express systray as a separate application under the site.

To avoid having to run VS as admin (lots of good reasons not to run as admin), add a netsh rule as follows (obviously replacing the IP and port with your values) - you'll need an admin cmd.exe for this, it only needs to be run once:

netsh http add urlacl url=http://192.168.1.121:51652/ user=\Everyone

netsh can add rules like url=http://+:51652/ but I failed to get this to place nicely with IIS Express. You can use netsh http show urlacl to list existing rules, and they can be deleted with netsh http delete urlacl url=blah.

        Set<String> wordSet = new HashSet<String>();

        readWordMap(wordSet, fileName);

It's always better to read the specs. There is no box-shadow-bottom property, and as Lea points out you should always place the un-prefixed property at the bottom, after the prefixed ones.

So it's:

.shadow {_x000D_
  -webkit-box-shadow: 0px 2px 4px #000000;_x000D_
  -moz-box-shadow: 0px 2px 4px #000000;_x000D_
  box-shadow: 0px 2px 4px #000000;_x000D_
}

<div class="shadow">Some content</div>

Edit elasticsearch.yml and add the following line

http.host: 0.0.0.0

network.host: 0.0.0.0 didn't work for

To see a list of HTTP request headers, you can use :

console.log(JSON.stringify(req.headers));

to return a list in JSON format.

{
"host":"localhost:8081",
"connection":"keep-alive",
"cache-control":"max-age=0",
"accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
"upgrade-insecure-requests":"1",
"user-agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.107 Safari/537.36",
"accept-encoding":"gzip, deflate, sdch",
"accept-language":"en-US,en;q=0.8,et;q=0.6"
}

Or with a constructor & linq with Select:

public class TargetType {
  public string Prop1 {get;set;}
  public string Prop1 {get;set;}

  // Constructor
  public TargetType(OrigType origType) {
    Prop1 = origType.Prop1;
    Prop2 = origType.Prop2;
  }
}

var origList = new List<OrigType>();
var targetList = origList.Select(s=> new TargetType(s)).ToList();  

The Linq line is more soft! ;-)

You need to set it in the value itself, not in the prepared statement SQL string.

So, this should do for a prefix-match:

notes = notes
    .replace("!", "!!")
    .replace("%", "!%")
    .replace("_", "!_")
    .replace("[", "![");
PreparedStatement pstmt = con.prepareStatement(
        "SELECT * FROM analysis WHERE notes LIKE ? ESCAPE '!'");
pstmt.setString(1, notes + "%");

or a suffix-match:

pstmt.setString(1, "%" + notes);

or a global match:

pstmt.setString(1, "%" + notes + "%");

I've also faced a similar situation where I needed a script which can take care of javac and then java(ing) my java program. So, I came up with this BATCH script.

::  @author Rudhin Menon

Above batch script will check the file for any changes and compile if any changes are done, you can tweak it for compiling whenever you want. Happy coding :)

Answer is adding this 2 lines of code to Global.asax.cs Application_Start method

var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = 
    Newtonsoft.Json.PreserveReferencesHandling.All;

Use current_url element for Python 2:

print browser.current_url

For Python 3 and later versions of selenium:

print(driver.current_url)

Just to be pedantic, some systems may not have an 8 bit type. According to Wikipedia:

An implementation is required to define exact-width integer types for N = 8, 16, 32, or 64 if and only if it has any type that meets the requirements. It is not required to define them for any other N, even if it supports the appropriate types.

So uint8_t isn't guaranteed to exist, though it will for all platforms where 8 bits = 1 byte. Some embedded platforms may be different, but that's getting very rare. Some systems may define char types to be 16 bits, in which case there probably won't be an 8-bit type of any kind.

Other than that (minor) issue, @Mark Ransom's answer is the best in my opinion. Use the one that most clearly shows what you're using the data for.

Also, I'm assuming you meant uint8_t (the standard typedef from C99 provided in the stdint.h header) rather than uint_8 (not part of any standard).

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

This may be possible by using the refs attribute.

In the example of wanting to to reach a <div> what you would want to do is use is <div ref="myExample">. Then you would be able to get that DOM node by using React.findDOMNode(this.refs.myExample).

From there getting the correct DOM node of each child may be as simple as mapping over this.refs.myExample.children(I haven't tested that yet) but you'll at least be able to grab any specific mounted child node by using the ref attribute.

Here's the official react documentation on refs for more info.

Lots of answers already exist here! I am answering this question with additional and reliable solutions:

Using PowerManager.WakeLock is not so reliable a solution, as the app requires additional permissions.

<uses-permission android:name="android.permission.WAKE_LOCK" />

Also, if it accidentally remains holding the wake lock, it can leave the screen on.

So, I recommend not using the PowerManager.WakeLock solution. Instead of this, use any of the following solutions:

First:

We can use getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); in onCreate()

@Override
        protected void onCreate(Bundle icicle) {
            super.onCreate(icicle);    
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        }

Second:

we can use keepScreenOn

1. implementation using setKeepScreenOn() in java code:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        View v = getLayoutInflater().inflate(R.layout.driver_home, null);// or any View (incase generated programmatically ) 
        v.setKeepScreenOn(true);
        setContentView(v);
       }

Docs http://developer.android.com/reference/android/view/View.html#setKeepScreenOn(boolean)

2. Adding keepScreenOn to xml layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:keepScreenOn="true" >

Docs http://developer.android.com/reference/android/view/View.html#attr_android%3akeepScreenOn

Notes (some useful points):

1. It doesn't matter that keepScreenOn should be used on a Main/Root/Parent View. It can be used with any child view and will work the same way it works in a parent view.
2. The only thing that matters is that the view's visibility must be visible. Otherwise, it will not work!

This is relatively simple if you use pylab (included with matplotlib) instead of matplotlib directly. Start off with a list of filenames and legend names, like [ ('name of file 1', 'label 1'), ('name of file 2', 'label 2'), ...]. Then you can use something like the following:

import pylab

datalist = [ ( pylab.loadtxt(filename), label ) for filename, label in list_of_files ]

for data, label in datalist:
    pylab.plot( data[:,0], data[:,1], label=label )

pylab.legend()
pylab.title("Title of Plot")
pylab.xlabel("X Axis Label")
pylab.ylabel("Y Axis Label")

You also might want to add something like fmt='o' to the plot command, in order to change from a line to points. By default, matplotlib with pylab plots onto the same figure without clearing it, so you can just run the plot command multiple times.

You're looking for UPDATE not insert.

UPDATE mytable
SET    table_column = 'test';

UPDATE will change the values of existing rows (and can include a WHERE to make it only affect specific rows), whereas INSERT is adding a new row (which makes it look like it changed only the last row, but in effect is adding a new row with that value).

Using directive it becomes easy and can be used throughout the application

HTML

<input type="text" placeholder="Enter value" numbersOnly>

As .keyCode() and .which() are deprecated, codes are checked using .key() Referred from

Directive:

@Directive({
   selector: "[numbersOnly]"
})

export class NumbersOnlyDirective {
  @Input() numbersOnly:boolean;

  navigationKeys: Array<string> = ['Backspace']; //Add keys as per requirement
  
  constructor(private _el: ElementRef) { }

  @HostListener('keydown', ['$event']) onKeyDown(e: KeyboardEvent) {
    
    if (
      // Allow: Delete, Backspace, Tab, Escape, Enter, etc
      this.navigationKeys.indexOf(e.key) > -1 || 
      (e.key === 'a' && e.ctrlKey === true) || // Allow: Ctrl+A
      (e.key === 'c' && e.ctrlKey === true) || // Allow: Ctrl+C
      (e.key === 'v' && e.ctrlKey === true) || // Allow: Ctrl+V
      (e.key === 'x' && e.ctrlKey === true) || // Allow: Ctrl+X
      (e.key === 'a' && e.metaKey === true) || // Cmd+A (Mac)
      (e.key === 'c' && e.metaKey === true) || // Cmd+C (Mac)
      (e.key === 'v' && e.metaKey === true) || // Cmd+V (Mac)
      (e.key === 'x' && e.metaKey === true) // Cmd+X (Mac)
    ) {
        return;  // let it happen, don't do anything
    }
    // Ensure that it is a number and stop the keypress
    if (e.key === ' ' || isNaN(Number(e.key))) {
      e.preventDefault();
    }
  }
}

Its quite simple dear you can use range validator

<asp:TextBox ID="TextBox2" runat="server" TextMode="Number"></asp:TextBox>
<asp:RangeValidator ID="RangeValidator1" runat="server"   
    ControlToValidate="TextBox2"   
    ErrorMessage="Invalid number. Please enter the number between 0 to 20."   
    MaximumValue="20" MinimumValue="0" Type="Integer"></asp:RangeValidator>   
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"   
    ControlToValidate="TextBox2" ErrorMessage="This is required field, can not be blank."></asp:RequiredFieldValidator>

otherwise you can use javascript

<script>
function minmax(value, min, max) 
{
    if(parseInt(value) < min || isNaN(parseInt(value))) 
        return 0; 
    else if(parseInt(value) > max) 
        return 20; 
    else return value;
}
</script>                        
<input type="text" name="TextBox1" id="TextBox1" maxlength="5"
onkeyup="this.value = minmax(this.value, 0, 20)" />

it can be useful : If you want to do it with Symfony forms :

 $today = new DateTime('now');
 $formBuilder->add('startDate', DateType::class, array(
                   'widget' => 'single_text',
                   'data'   => new \DateTime(),
                   'attr'   => ['min' => $today->format('Y-m-d')]
                   ));

If you keep a backup of your worskpace folder, then all you need to do is restore the following folder from the backup:

workspace/.metadata/.plugins/org.eclipse.core.resources

actually @bazzlebrush 's answer and @filoxo 's comment helped me a lot.

I needed to find the elements where the class could be "zA yO" OR "zA zE"

Using jquery I first select the parent of the desired elements:

(a div with class starting with 'abc' and style != 'display:none')

var tom = $('div[class^="abc"][style!="display: none;"]')[0];                   

then the desired children of that element:

var ax = tom.querySelectorAll('.zA.yO, .zA.zE');

works perfectly! note you don't have to do document.querySelector you can as above pass in a pre-selected object.

public static void selectSpinnerItemByValue(Spinner spnr, long value) {
    SimpleCursorAdapter adapter = (SimpleCursorAdapter) spnr.getAdapter();
    for (int position = 0; position < adapter.getCount(); position++) {
        if(adapter.getItemId(position) == value) {
            spnr.setSelection(position);
            return;
        }
    }
}

You can use the above like:

selectSpinnerItemByValue(spinnerObject, desiredValue);

& of course you can also select by index directly like

spinnerObject.setSelection(index);

git remote rm origin
git remote add origin <remote url>

According to WikiPedia, you can specify which favicon file to load using the link tag in the head section, with a parameter of rel="icon".

For example:

 <link rel="icon" type="image/png" href="/path/image.png">

I imagine if you wanted to write some dynamic content for that call, you would have access to cookies so you could retrieve your session information that way and present appropriate content.

You may fall foul of file formats (IE reportedly only supports it's .ICO format, whilst most everyone else supports PNG and GIF images) and possibly caching issues, both on the browser and through proxies. This would be because of the original itention of favicon, specifically, for marking a bookmark with a site's mini-logo.

Nothing elegant but this could be another satisfactory answer.

merge(x = DF1, y = DF2, by = "Client", all.x=TRUE)[,c("Client","LO","CON")]

This will be useful especially when you don't need the keys that were used to join the tables in your results.

For example this is my html template:

<select class="custom-select d-block w-100" id="genre" name="genre"
                  [(ngModel)]="film.genre"
                  #genreInput="ngModel"
                  required>
            <option value="">Choose...</option>
            <option *ngFor="let genre of genres;" [value]="genre.value">{{genre.name}}</option>
          </select>

This is the field that binded with template from my Component:

  // Genres of films like action or drama that will populate dropdown list.
  genres: Genre[];

I fetch genres of films from server dynamically. In order do communicate with server I have created FilmService

This is the method which communicate server:

 fetchGenres(): Observable<Genre[]> {
    return this.client.get(WebUtils.RESOURCE_HOST_API + 'film' + '/genre') as Observable<Genre[]>;
  }

Why this method returns Observable<Genre[]> not something like Genre[]?

JavaScript is async and it does not wait for a method to return value after an expensive process. With expensive I mean a process that take a time to return value. Like fetching data from server. So you have to return reference of Observable and subscribe it.

For example in my Component :

ngOnInit() {
    this.filmService.fetchGenres().subscribe(
      val => this.genres = val
    );
  }

just my couple cents... the practice that I often use is to organize the methods like this as a custom helper

public static class StreamHelpers
{
    public static byte[] ReadFully(this Stream input)
    {
        using (MemoryStream ms = new MemoryStream())
        {
            input.CopyTo(ms);
            return ms.ToArray();
        }
    }
}

add namespace to the config file and use it anywhere you wish

Below works for first tr of the table under thead

table thead tr:first-child {
   background: #f2f2f2;
}

And this works for the first tr of thead and tbody both:

table thead tbody tr:first-child {
   background: #f2f2f2;
}

Fairly straightforward:

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD

You should consider using an angular plug-in to handle the heavy lifting for you, unless you particularly enjoy typing hundreds of lines of knarly error prone ion-grid code. Simon Grimm has a cracking step by step tutorial that anyone can follow: https://devdactic.com/ionic-datatable-ngx-datatable/. This shows how to use ngx-datatable. But there are many other options (ng2-table is good).

The dead simple example goes like this:

<ion-content>
  <ngx-datatable class="fullscreen" [ngClass]="tablestyle" [rows]="rows" [columnMode]="'force'" [sortType]="'multi'" [reorderable]="false">
    <ngx-datatable-column name="Name"></ngx-datatable-column>
    <ngx-datatable-column name="Gender"></ngx-datatable-column>
    <ngx-datatable-column name="Age"></ngx-datatable-column>
  </ngx-datatable>
</ion-content>

And the ts:

rows = [
    {
      "name": "Ethel Price",
      "gender": "female",
      "age": 22
    },
    {
      "name": "Claudine Neal",
      "gender": "female",
      "age": 55
    },
    {
      "name": "Beryl Rice",
      "gender": "female",
      "age": 67
    },
    {
      "name": "Simon Grimm",
      "gender": "male",
      "age": 28
    }
  ];

Since the original poster expressed their frustration of how difficult it is to achieve this with ion-grid, I think the correct answer should not be constrained by this as a prerequisite. You would be nuts to roll your own, given how good this is!

var length = $('#mySelectList').children('option').length;

or

var length = $('#mySelectList > option').length;

This assumes your <select> list has an ID of mySelectList.

• http://api.jquery.com/children/
• http://api.jquery.com/child-selector/

I have another way to do this... suppose you swap out your message converter to String for your RestTemplate, then you can receive raw JSON. Using the raw JSON, you can then map it into your Generic Collection using a Jackson Object Mapper. Here's how:

Swap out the message converter:

    List<HttpMessageConverter<?>> oldConverters = new ArrayList<HttpMessageConverter<?>>();
    oldConverters.addAll(template.getMessageConverters());

    List<HttpMessageConverter<?>> stringConverter = new ArrayList<HttpMessageConverter<?>>();
    stringConverter.add(new StringHttpMessageConverter());

    template.setMessageConverters(stringConverter);

Then get your JSON response like this:

    ResponseEntity<String> response = template.exchange(uri, HttpMethod.GET, null, String.class);

Process the response like this:

     String body = null;
     List<T> result = new ArrayList<T>();
     ObjectMapper mapper = new ObjectMapper();

     if (response.hasBody()) {
        body = items.getBody();
        try {
            result = mapper.readValue(body, mapper.getTypeFactory().constructCollectionType(List.class, clazz));
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            template.setMessageConverters(oldConverters);
        }
        ...

I am using texmaker as the editor. you have to compile it in terminal as following:

1. pdflatex filename (with or without extensions)
2. bibtex filename (without extensions)
3. pdflatex filename (with or without extensions)
4. pdflatex filename (with or without extensions)

but sometimes, when you use \citep{}, the names of the references don't show up. In this case, I had to open the references.bib file , so that texmaker could capture the references from the references.bib file. After every edition of the bib file, I had to close and reopen it!! So that texmaker could capture the content of new .bbl file each time. But remember, you have to also run your code in texmaker too.

I got this error in a JobService from the following code:

    BluetoothLeScanner bluetoothLeScanner = getBluetoothLeScanner();
    if (BluetoothAdapter.STATE_ON == getBluetoothAdapter().getState() && null != bluetoothLeScanner) {
        // ...
    } else {
        Logger.debug(TAG, "BluetoothAdapter isn't on so will attempting to turn on and will retry starting scanning in a few seconds");
        getBluetoothAdapter().enable();
        (new Handler()).postDelayed(new Runnable() {

            public void run() {
                startScanningBluetooth();
            }
        }, 5000);
    }

The service crashed:

                }
            }, 5000);

Now the code doesn't throw the RuntimeException anymore.

You can find what is the php.ini file used:

• By add phpinfo() in a php page and display the page (like the picture under)
• From the shell, enter: php -i

Next, you can find the information in the Loaded Configuration file (so here it's /user/local/etc/php/php.ini)

Sometimes, you have indicated (none), in this case you just have to put your custom php.ini that you can find here: http://git.php.net/?p=php-src.git;a=blob;f=php.ini-production;hb=HEAD

I hope this answer will help.

The method Socket.Available will immediately throw a SocketException if the remote system has disconnected/closed the connection.

Ignoring the smooth interpolation between points in your example graph (that would require doing some manual interpolation, or just have a higher resolution of your data), you can use pyplot.fill_between():

from matplotlib import pyplot as plt
import numpy as np

x = np.linspace(0, 30, 30)
y = np.sin(x/6*np.pi)
error = np.random.normal(0.1, 0.02, size=y.shape)
y += np.random.normal(0, 0.1, size=y.shape)

plt.plot(x, y, 'k-')
plt.fill_between(x, y-error, y+error)
plt.show()

See also the matplotlib examples.

Try this code:

$('#iframe').contents().find("html").html();

This will return all the html in your iframe. Instead of .find("html") you can use any selector you want eg: .find('body'),.find('div#mydiv').

For everyone who is on windows and couldn't solve the duplicating bars issue with any of the solutions mentioned here. I had to install the colorama package as stated in tqdm's known issues which fixed it.

pip install colorama

Try it with this example:

from tqdm import tqdm
from time import sleep

for _ in tqdm(range(5), "All", ncols = 80, position = 0):
    for _ in tqdm(range(100), "Sub", ncols = 80, position = 1, leave = False):
        sleep(0.01)

Which will produce something like:

All:  60%|¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦                | 3/5 [00:03<00:02,  1.02s/it]
Sub:  50%|¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦                  | 50/100 [00:00<00:00, 97.88it/s]

Yes typically, a session will end after 20 minutes in PHP.

2019 modern browsers update

This is the approach I'd now recommend with a few caveats:

• A relatively modern browser is required
• If the file is expected to be very large you should likely do something similar to the original approach (iframe and cookie) because some of the below operations could likely consume system memory at least as large as the file being downloaded and/or other interesting CPU side effects.

fetch('https://jsonplaceholder.typicode.com/todos/1')_x000D_
  .then(resp => resp.blob())_x000D_
  .then(blob => {_x000D_
    const url = window.URL.createObjectURL(blob);_x000D_
    const a = document.createElement('a');_x000D_
    a.style.display = 'none';_x000D_
    a.href = url;_x000D_
    // the filename you want_x000D_
    a.download = 'todo-1.json';_x000D_
    document.body.appendChild(a);_x000D_
    a.click();_x000D_
    window.URL.revokeObjectURL(url);_x000D_
    alert('your file has downloaded!'); // or you know, something with better UX..._x000D_
  })_x000D_
  .catch(() => alert('oh no!'));

2012 Original jQuery/iframe/Cookie based approach

Bluish is completely right about this, you can't do it through Ajax because JavaScript cannot save files directly to a user's computer (out of security concerns). Unfortunately pointing the main window's URL at your file download means you have little control over what the user experience is when a file download occurs.

I created jQuery File Download which allows for an "Ajax like" experience with file downloads complete with OnSuccess and OnFailure callbacks to provide for a better user experience. Take a look at my blog post on the common problem that the plugin solves and some ways to use it and also a demo of jQuery File Download in action. Here is the source

Here is a simple use case demo using the plugin source with promises. The demo page includes many other, 'better UX' examples as well.

$.fileDownload('some/file.pdf')
    .done(function () { alert('File download a success!'); })
    .fail(function () { alert('File download failed!'); });

Depending on what browsers you need to support you may be able to use https://github.com/eligrey/FileSaver.js/ which allows more explicit control than the IFRAME method jQuery File Download uses.

If you mean delete every instance of all models, I would use

ActiveRecord::Base.connection.tables.map(&:classify)
  .map{|name| name.constantize if Object.const_defined?(name)}
  .compact.each(&:delete_all)

Set the type of the field as TIMESTAMP too.

Doing alist = [] does not clear the list, just creates an empty list and binds it to the variable alist. The old list will still exist if it had other variable bindings.

To actually clear a list in-place, you can use any of these ways:

1. alist.clear() # Python 3.3+, most obvious
2. del alist[:]
3. alist[:] = []
4. alist *= 0 # fastest

See the Mutable Sequence Types documentation page for more details.

When we return a value from Stored procedure without select statement. We need to use "ParameterDirection.ReturnValue" and "ExecuteScalar" command to get the value.

CREATE PROCEDURE IsEmailExists
    @Email NVARCHAR(20)
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    IF EXISTS(SELECT Email FROM Users where Email = @Email)
    BEGIN
        RETURN 0 
    END
    ELSE
    BEGIN
        RETURN 1
    END
END

in C#

GetOutputParaByCommand("IsEmailExists")

public int GetOutputParaByCommand(string Command)
        {
            object identity = 0;
            try
            {
                mobj_SqlCommand.CommandText = Command;
                SqlParameter SQP = new SqlParameter("returnVal", SqlDbType.Int);
                SQP.Direction = ParameterDirection.ReturnValue;
                mobj_SqlCommand.Parameters.Add(SQP);
                mobj_SqlCommand.Connection = mobj_SqlConnection;
                mobj_SqlCommand.ExecuteScalar();
                identity = Convert.ToInt32(SQP.Value);
                CloseConnection();
            }
            catch (Exception ex)
            {

                CloseConnection();
            }
            return Convert.ToInt32(identity);
        }

We get the returned value of SP "IsEmailExists" using above c# function.

i use this for 3.6+

import subprocess
def execute(cmd):
    """
        Purpose  : To execute a command and return exit status
        Argument : cmd - command to execute
        Return   : result, exit_code
    """
    process = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    (result, error) = process.communicate()
    rc = process.wait()
    if rc != 0:
        print ("Error: failed to execute command: ", cmd)
        print (error.rstrip().decode("utf-8"))
    return result.rstrip().decode("utf-8"), serror.rstrip().decode("utf-8")

HERE is another open source library on GitHub named EvalEx.

Unlike the JavaScript engine this library is focused in evaluating mathematical expressions only. Moreover, the library is extensible and supports use of boolean operators as well as parentheses.

when reimporting your keys from the old keyring, you need to specify the command:

gpg --allow-secret-key-import --import <keyring>

otherwise it will only import the public keys, not the private keys.

I'm new here and don't have the reputation to comment or downvote, but wanted to point out a flaw in the example in Andy White's reply:

try
{
    SomethingThatCausesAnException();
    Assert.Fail("Should have exceptioned above!");
}
catch (Exception ex)
{
    // whatever logging code
}

In all unit testing frameworks I am familiar with, Assert.Fail works by throwing an exception, so the generic catch will actually mask the failure of the test. If SomethingThatCausesAnException() does not throw, the Assert.Fail will, but that will never bubble out to the test runner to indicate failure.

If you need to catch the expected exception (i.e., to assert certain details, like the message / properties on the exception), it's important to catch the specific expected type, and not the base Exception class. That would allow the Assert.Fail exception to bubble out (assuming you aren't throwing the same type of exception that your unit testing framework does), but still allow validation on the exception that was thrown by your SomethingThatCausesAnException() method.

Map<K,V> is an interface, HashMap<K,V> is a class that implements Map.

you can do

Map<Key,Value> map = new HashMap<Key,Value>();

Here you have a link to the documentation of each one: Map, HashMap.

little trick

getCurrentScript and getCurrentScriptPath

I came up with the following:

//Thanks to https://stackoverflow.com/a/27369985/5175935
var getCurrentScript = function () {

    if ( document.currentScript && ( document.currentScript.src !== '' ) )
        return document.currentScript.src;
    var scripts = document.getElementsByTagName( 'script' ),
        str = scripts[scripts.length - 1].src;
    if ( str !== '' )
        return src;
    //Thanks to https://stackoverflow.com/a/42594856/5175935
    return new Error().stack.match(/(https?:[^:]*)/)[0];

};

//Thanks to https://stackoverflow.com/a/27369985/5175935
var getCurrentScriptPath = function () {
    var script = getCurrentScript(),
        path = script.substring( 0, script.lastIndexOf( '/' ) );
    return path;
};

set a WebViewClient to your WebView, start your progress dialog on you onCreate() method an dismiss it when the page has finished loading in onPageFinished(WebView view, String url)

</LinearLayout>

I tried to call

startService(oIntent);
bindService(oIntent, mConnection, Context.BIND_AUTO_CREATE);

consequently and I could create a sticky service and bind to it. Detailed tutorial for Bound Service Example.

Selector name{
font-weight:bold;
}

Suppose you want to make bold for p element

p{
font-weight:bold;
}

You can use other alternative value instead of bold like

p{
 font-weight:bolder;
 font-weight:600;
}

For those who want to just copy and paste the fastest implementation of shift, there is a benchmark and conclusion(see the end). In addition, I introduce fill_value parameter and fix some bugs.

Benchmark

import numpy as np
import timeit

# enhanced from IronManMark20 version
def shift1(arr, num, fill_value=np.nan):
    arr = np.roll(arr,num)
    if num < 0:
        arr[num:] = fill_value
    elif num > 0:
        arr[:num] = fill_value
    return arr

# use np.roll and np.put by IronManMark20
def shift2(arr,num):
    arr=np.roll(arr,num)
    if num<0:
         np.put(arr,range(len(arr)+num,len(arr)),np.nan)
    elif num > 0:
         np.put(arr,range(num),np.nan)
    return arr

# use np.pad and slice by me.
def shift3(arr, num, fill_value=np.nan):
    l = len(arr)
    if num < 0:
        arr = np.pad(arr, (0, abs(num)), mode='constant', constant_values=(fill_value,))[:-num]
    elif num > 0:
        arr = np.pad(arr, (num, 0), mode='constant', constant_values=(fill_value,))[:-num]

    return arr

# use np.concatenate and np.full by chrisaycock
def shift4(arr, num, fill_value=np.nan):
    if num >= 0:
        return np.concatenate((np.full(num, fill_value), arr[:-num]))
    else:
        return np.concatenate((arr[-num:], np.full(-num, fill_value)))

# preallocate empty array and assign slice by chrisaycock
def shift5(arr, num, fill_value=np.nan):
    result = np.empty_like(arr)
    if num > 0:
        result[:num] = fill_value
        result[num:] = arr[:-num]
    elif num < 0:
        result[num:] = fill_value
        result[:num] = arr[-num:]
    else:
        result[:] = arr
    return result

arr = np.arange(2000).astype(float)

def benchmark_shift1():
    shift1(arr, 3)

def benchmark_shift2():
    shift2(arr, 3)

def benchmark_shift3():
    shift3(arr, 3)

def benchmark_shift4():
    shift4(arr, 3)

def benchmark_shift5():
    shift5(arr, 3)

benchmark_set = ['benchmark_shift1', 'benchmark_shift2', 'benchmark_shift3', 'benchmark_shift4', 'benchmark_shift5']

for x in benchmark_set:
    number = 10000
    t = timeit.timeit('%s()' % x, 'from __main__ import %s' % x, number=number)
    print '%s time: %f' % (x, t)

benchmark result:

benchmark_shift1 time: 0.265238
benchmark_shift2 time: 0.285175
benchmark_shift3 time: 0.473890
benchmark_shift4 time: 0.099049
benchmark_shift5 time: 0.052836

Conclusion

shift5 is winner! It's OP's third solution.

1. option 1

   echo $(cat testfile)
   

2. Option 2

   tr ' ' '\n' < testfile
   

If you know the settings in advance you can define it in a single statement:

var defaultsettings = {
                        ajaxsettings : { "ak1" : "v1", "ak2" : "v2", etc. },
                        uisettings : { "ui1" : "v1", "ui22" : "v2", etc }
                      };

If you don't know the values in advance you can just define the top level object and then add properties:

var defaultsettings = { };
defaultsettings["ajaxsettings"] = {};
defaultsettings["ajaxsettings"]["somekey"] = "some value";

Or half-way between the two, define the top level with nested empty objects as properties and then add properties to those nested objects:

var defaultsettings = {
                        ajaxsettings : {  },
                        uisettings : {  }
                      };

defaultsettings["ajaxsettings"]["somekey"] = "some value";
defaultsettings["uisettings"]["somekey"] = "some value";

You can nest as deep as you like using the above techniques, and anywhere that you have a string literal in the square brackets you can use a variable:

var keyname = "ajaxsettings";
var defaultsettings = {};
defaultsettings[keyname] = {};
defaultsettings[keyname]["some key"] = "some value";

Note that you can not use variables for key names in the { } literal syntax.

Each HTML element has an innerHTML property that defines both the HTML code and the text that occurs between that element's opening and closing tag. By changing an element's innerHTML after some user interaction, you can make much more interactive pages.

However, using innerHTML requires some preparation if you want to be able to use it easily and reliably. First, you must give the element you wish to change an id. With that id in place you will be able to use the getElementById function, which works on all browsers.

After seeing this for deeply getting attributes, I made the following to safely get nested dict values using dot notation. This works for me because my dicts are deserialized MongoDB objects, so I know the key names don't contain .s. Also, in my context, I can specify a falsy fallback value (None) that I don't have in my data, so I can avoid the try/except pattern when calling the function.

from functools import reduce # Python 3
def deepgetitem(obj, item, fallback=None):
    """Steps through an item chain to get the ultimate value.

    If ultimate value or path to value does not exist, does not raise
    an exception and instead returns `fallback`.

    >>> d = {'snl_final': {'about': {'_icsd': {'icsd_id': 1}}}}
    >>> deepgetitem(d, 'snl_final.about._icsd.icsd_id')
    1
    >>> deepgetitem(d, 'snl_final.about._sandbox.sbx_id')
    >>>
    """
    def getitem(obj, name):
        try:
            return obj[name]
        except (KeyError, TypeError):
            return fallback
    return reduce(getitem, item.split('.'), obj)

Use git clone c:/folder1 c:/folder2

git clone [--template=<template_directory>] [-l] [-s] [--no-hardlinks]
[-q] [-n] [--bare] [--mirror] [-o <name>] [-b <name>] [-u <upload-pack>]
[--reference <repository>] [--separate-git-dir <git dir>] [--depth <depth>]
[--[no-]single-branch] [--recursive|--recurse-submodules] [--]<repository>
[<directory>]


<repository>

    The (possibly remote) repository to clone from.
    See the URLS section below for more information on specifying repositories.
<directory>

    The name of a new directory to clone into.
    The "humanish" part of the source repository is used if no directory 
    is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
    Cloning into an existing directory is only allowed if the directory is empty.

Here is my answer using the group by clause.

SELECT *
FROM feeds f
LEFT JOIN 
(
    SELECT artist_id, feed_id
    FROM feeds_artists
    GROUP BY artist_id, feed_id 
) fa ON fa.feed_id = f.id
LEFT JOIN artists a ON a.artist_id = fa.artist_id

Using docker-compose, services are exposed to each other by name by default. Docs.
You could also specify an alias like;

version: '2.1'
services:
  mongo:
    image: mongo:3.2.11
  redis:
    image: redis:3.2.10
  api:
    image: some-image
    depends_on:
      - mongo
      - solr
    links:
      - "mongo:mongo.openconceptlab.org"
      - "solr:solr.openconceptlab.org"
      - "some-service:some-alias"

And then access the service using the specified alias as a host name, e.g mongo.openconceptlab.org for mongo in this case.

If you're interested, I managed version numbers automatically from git infos here under the format

<major>.<minor>.<patch>-b<build>

where build is the total number of commits. You'll see the interesting code in the Makefile. Here is the relevant part to access the different part of the version number:

LAST_TAG_COMMIT = $(shell git rev-list --tags --max-count=1)
LAST_TAG = $(shell git describe --tags $(LAST_TAG_COMMIT) )
TAG_PREFIX = "latex-tutorial-v"

VERSION  = $(shell head VERSION)
# OR try to guess directly from the last git tag
#VERSION    = $(shell  git describe --tags $(LAST_TAG_COMMIT) | sed "s/^$(TAG_PREFIX)//")
MAJOR      = $(shell echo $(VERSION) | sed "s/^\([0-9]*\).*/\1/")
MINOR      = $(shell echo $(VERSION) | sed "s/[0-9]*\.\([0-9]*\).*/\1/")
PATCH      = $(shell echo $(VERSION) | sed "s/[0-9]*\.[0-9]*\.\([0-9]*\).*/\1/")
# total number of commits       
BUILD      = $(shell git log --oneline | wc -l | sed -e "s/[ \t]*//g")

#REVISION   = $(shell git rev-list $(LAST_TAG).. --count)
#ROOTDIR    = $(shell git rev-parse --show-toplevel)
NEXT_MAJOR_VERSION = $(shell expr $(MAJOR) + 1).0.0-b$(BUILD)
NEXT_MINOR_VERSION = $(MAJOR).$(shell expr $(MINOR) + 1).0-b$(BUILD)
NEXT_PATCH_VERSION = $(MAJOR).$(MINOR).$(shell expr $(PATCH) + 1)-b$(BUILD)

I fixed this issue on my debian GNU/Linux system by overiding system rules that way :

mv  /etc/udev/rules.d/51-android.rules /etc/udev/rules.d/99-android.rules

I used contents from files linked at : http://rootzwiki.com/topic/258-udev-rules-for-any-device-no-more-starting-adb-with-sudo/

I just created a simple timer using the MVP pattern (however it may be overkill for that simple project). It has quit, start/pause and a stop button. Time is displayed in HH:MM:SS format. Time counting is implemented using a thread that is running several times a second and the difference between the time the timer has started and the current time.

Source code on github

Remove the file: C:/Sites/folder/Pids/Server.pids

Explanation In UNIX land at least we usually track the process id (pid) in a file like server.pid. I think this is doing the same thing here. That file was probably left over from a crash.

Improved @haitaka answer, using the key and predicate

function  deepSearch (object, key, predicate) {
    if (object.hasOwnProperty(key) && predicate(key, object[key]) === true) return object

    for (let i = 0; i < Object.keys(object).length; i++) {
      let value = object[Object.keys(object)[i]];
      if (typeof value === "object" && value != null) {
        let o = deepSearch(object[Object.keys(object)[i]], key, predicate)
        if (o != null) return o
      }
    }
    return null
}

So this can be invoked as:

var result = deepSearch(myObject, 'id', (k, v) => v === 1);

or

var result = deepSearch(myObject, 'title', (k, v) => v === 'Some Recommends');

Here is the demo: http://jsfiddle.net/a21dx6c0/

EDITED

In the same way you can find more than one object

function deepSearchItems(object, key, predicate) {
        let ret = [];
        if (object.hasOwnProperty(key) && predicate(key, object[key]) === true) {
            ret = [...ret, object];
        }
        if (Object.keys(object).length) {
            for (let i = 0; i < Object.keys(object).length; i++) {
                let value = object[Object.keys(object)[i]];
                if (typeof value === "object" && value != null) {
                    let o = this.deepSearchItems(object[Object.keys(object)[i]], key, predicate);
                    if (o != null && o instanceof Array) {
                        ret = [...ret, ...o];
                    }
                }
            }
        }
        return ret;
    }

I'm not sure what your problem is (since you haven't told us), but I'm guessing at

a = Console.Read();

This will only read one character from your Console.

You can change your program to this. To make it more robust, accept more than 1 char input, and validate that the input is actually a number:

double a, b;
Console.WriteLine("istenen sayiyi sonuna .00 koyarak yaz");
if (double.TryParse(Console.ReadLine(), out a)) {
  b = a * Math.PI;
  Console.WriteLine("Sonuç " + b);

First initialize Property values

MutablePropertyValues mutablePropertyValues = new MutablePropertyValues();
mutablePropertyValues.add("hostName", details.getHostName());
mutablePropertyValues.add("port", details.getPort());

DefaultListableBeanFactory context = new DefaultListableBeanFactory();
GenericBeanDefinition connectionFactory = new GenericBeanDefinition();
connectionFactory.setBeanClass(Class);
connectionFactory.setPropertyValues(mutablePropertyValues);

context.registerBeanDefinition("beanName", connectionFactory);

Add to the list of beans

ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext).getBeanFactory();
beanFactory.registerSingleton("beanName", context.getBean("beanName"));

A PIL only solution for creating a bi-level (black and white) image with a custom threshold:

from PIL import Image
img = Image.open('mB96s.png')
thresh = 200
fn = lambda x : 255 if x > thresh else 0
r = img.convert('L').point(fn, mode='1')
r.save('foo.png')

With just

r = img.convert('1')
r.save('foo.png')

you get a dithered image.

From left to right the input image, the black and white conversion result and the dithered result:

You can click on the images to view the unscaled versions.

For me it is like this,

1. Access

   • Linked Lists allow only sequential access to elements. Thus the algorithmic complexities is order of O(n)
   • Arrays allow random access to its elements and thus the complexity is order of O(1)

2. Storage

   • Linked lists require an extra storage for references. This makes them impractical for lists of small data items such as characters or boolean values.
   • Arrays do not need an extra storage to point to next data item. Each element can be accessed via indexes.

3. Size

   • The size of Linked lists are dynamic by nature.
   • The size of array is restricted to declaration.

4. Insertion/Deletion

   • Elements can be inserted and deleted in linked lists indefinitely.
   • Insertion/Deletion of values in arrays are very expensive. It requires memory reallocation.

See How do I create arrays in a HTML <form>? in the PHP and HTML FAQ.

Use printf, not echo.

There are multiple different versions of the echo command. There's /bin/echo (which may or may not be the GNU Coreutils version, depending on the system), and the echo command is built into most shells. Different versions have different ways (or no way) to specify or disable escapes for control characters.

printf, on the other hand, has much less variation. It can exist as a command, typically /bin/printf, and it's built into some shells (bash and zsh have it, tcsh and ksh don't), but the various versions are much more similar to each other than the different versions of echo are. And you don't have to remember command-line options (with a few exceptions; GNU Coreutils printf accepts --version and --help, and the built-in bash printf accepts -v var to store the output in a variable).

For your example:

res='           'x # res = "\t\tx"
printf '%s\n' "[$res]"

And now it's time for me to admit that echo will work just as well for the example you're asking about; you just need to put double quotes around the argument:

echo "[$res]"

as kmkaplan wrote (two and a half years ago, I just noticed!). The problem with your original commands:

res='           'x # res = "\t\tx"
echo '['$res']' # expect [\t\tx]

isn't with echo; it's that the shell replaced the tab with a space before echo ever saw it.

echo is fine for simple output, like echo hello world, but you should use printf whenever you want to do something more complex. You can get echo to work, but the resulting code is likely to fail when you run it with a different echo implementation or a different shell.

I had to delete Tomcat's work directory as it had cached previously generated files. To do this:

1. Stop Tomcat
2. Delete the 'work' directory
3. Start Tomcat

This will cause the work directory to be newly generated.

After adding php directory in User Settings,

{
    "php.validate.executablePath": "C:/phpdirectory/php7.1.8/php.exe",
    "php.executablePath": "C:/phpdirectory/php7.1.8/php.exe"
}

If you still have this error, please verify you have installed :

• 64-bit or 32-bit version of php (x64 or x86), depending on your OS;

• some librairies like Visual C++ Redistributable for Visual Studio 2015 : http://www.microsoft.com/en-us/download/details.aspx?id=48145;

To test if you PHP exe is ok, open cmd.exe :

c:/prog/php-7.1.8-Win32-VC14-x64/php.exe --version

If PHP fails, a message will be prompted with the error (missing dll for example).

There is a neat way of doing this.

• If it's an Unit Test you can do this:

  @RunWith(MockitoJUnitRunner.class)
  public class MyUnitTest {
  
      @Mock
      private MyFirstMock myFirstMock;
  
      @Mock
      private MySecondMock mySecondMock;
  
      @Spy
      private MySpiedClass mySpiedClass = new MySpiedClass();
  
      // It's gonna inject the 2 mocks and the spied object per reflection to this object
      // The java doc of @InjectMocks explains it really well how and when it does the injection
      @InjectMocks
      private MyClassToTest myClassToTest;
  
      @Test
      public void testSomething() {
      }
  }
  

• EDIT: If it's an Integration test you can do this(not intended to be used that way with Spring. Just showcase that you can initialize mocks with diferent Runners):

  @RunWith(SpringJUnit4ClassRunner.class)
  @ContextConfiguration("aplicationContext.xml")
  public class MyIntegrationTest {
  
      @Mock
      private MyFirstMock myFirstMock;
  
      @Mock
      private MySecondMock mySecondMock;
  
      @Spy
      private MySpiedClass mySpiedClass = new MySpiedClass();
  
      // It's gonna inject the 2 mocks and the spied object per reflection to this object
      // The java doc of @InjectMocks explains it really well how and when it does the injection
      @InjectMocks
      private MyClassToTest myClassToTest;
  
      @Before
      public void setUp() throws Exception {
            MockitoAnnotations.initMocks(this);
      }
  
      @Test
      public void testSomething() {
      }
  }
  

238! I checked it under Win7 32 bit with the following bat script:

set "fname="

@echo %fname%

goto :EOF

set "fname=%fname%_123456789"
goto :EOF

@echo xx>%fname%
if not exist %fname% goto :eof

I found that using the latest version will fix this problem:

You can use like this.

when: condition1 == "condition1" or condition2 == "condition2"

Also Please refer to this gist: https://gist.github.com/marcusphi/6791404

I recast Brajesh Kumar's answer above into Clojure as follows:

(defn open-browser 
  "Open a new browser (window or tab) viewing the document at this `uri`."
  [uri]
  (if (java.awt.Desktop/isDesktopSupported)
    (let [desktop (java.awt.Desktop/getDesktop)]
      (.browse desktop (java.net.URI. uri)))
    (let [rt (java.lang.Runtime/getRuntime)]
      (.exec rt (str "xdg-open " uri)))))

in case it's useful to anyone.

The newline character is actually '\n'.

It's pure JS. There are a bunch of date functions inside that allow you to convert date into week number and viceversa :)

Here is my layout:

    <HorizontalScrollView
        android:id="@+id/horizontalScrollView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/padding" >

       <LinearLayout
        android:id="@+id/shapeLayout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" >
        </LinearLayout>
    </HorizontalScrollView>

And I populate it in the code with dynamic check-boxes.

Frankly the errors are really hard to see, especially if only one character is "underwaved" in a sea of Java code. I used the instructions above to make the background an orangey-red color and things are much more obvious.

It can be done simply by using the following codes inside onCreate. By using android's default layout

Snackbar.make(findViewById(android.R.id.content),"Your Message",Snackbar.LENGTH_LONG).show();

Just use the below code. It will shadow surround the entire DIV

-webkit-box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);
-moz-box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);
box-shadow: -1px 1px 5px 9px rgba(0,0,0,0.75);

Hope this will work

int sizepuede= listaoptionVO.size();
for (int i = 0; i < sizepuede; i++) {
    if(listaoptionVO.get(i).getDescripcionRuc()==null){
        listaoptionVO.remove(listaoptionVO.get(i));
        i--;
        sizepuede--;
     }
}

edit: added indentation

this is what i did with one navigation icon and one Text view now you can make an extension to apply it where ever you need it. but you have to apply it on every activity

(toolbar[0] as AppCompatTextView).let {
            it.viewTreeObserver.addOnDrawListener {
                it.layoutParams = it.layoutParams.apply {
                    width = Toolbar.LayoutParams.MATCH_PARENT
                    (this as ViewGroup.MarginLayoutParams).apply {
                        marginEnd = toolbar[1].width
                    }
                }
                it.textAlignment = View.TEXT_ALIGNMENT_CENTER
            }

        }

A workaround is to use a willAnswer() method.

For example the following works (and doesn't throw a MockitoException but actually throws a checked Exception as required here) using BDDMockito:

given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });

The equivalent for plain Mockito would to use the doAnswer method

# function to insert a number in an sorted list


def pstatement(value_returned):
    return print('new sorted list =', value_returned)


def insert(input, n):
    print('input list = ', input)
    print('number to insert = ', n)
    print('range to iterate is =', len(input))

    first = input[0]
    print('first element =', first)
    last = input[-1]
    print('last element =', last)

    if first > n:
        list = [n] + input[:]
        return pstatement(list)
    elif last < n:
        list = input[:] + [n]
        return pstatement(list)
    else:
        for i in range(len(input)):
            if input[i] > n:
                break
    list = input[:i] + [n] + input[i:]
    return pstatement(list)

# Input values
listq = [2, 4, 5]
n = 1

insert(listq, n)

A space in a CSS selector selects child elements.

.btn input

This is basically what you wrote and it would select <input> elements within any element that has the btn class.

I think you're looking for

input[disabled].btn:hover, input[disabled].btn:active, input[disabled].btn:focus

This would select <input> elements with the disabled attribute and the btn class in the three different states of hover, active and focus.

I moved my home directory from one mac to another (Mountain Lion to Yosemite) and didn't realize about the broken virtualenv until I lost hold of the old laptop. I had the virtualenv point to Python 2.7 installed by brew and since Yosemite came with Python 2.7, I wanted to update my virtualenv to the system python. When I ran virtualenv on top of the existing directory, I was getting OSError: [Errno 17] File exists: '/Users/hdara/bin/python2.7/lib/python2.7/config' error. By trial and error, I worked around this issue by removing a few links and fixing up a few more manually. This is what I finally did (similar to what @Rockalite did, but simpler):

cd <virtualenv-root>
rm lib/python2.7/config
rm lib/python2.7/lib-dynload
rm include/python2.7
rm .Python
cd lib/python2.7
gfind . -type l -xtype l | while read f; do ln -s -f /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/${f#./} $f; done

After this, I was able to just run virtualenv on top of the existing directory.

From Docker 17.06 onwards, a special Mac-only DNS name is available in docker containers that resolves to the IP address of the host. It is:

docker.for.mac.localhost

The documentation is here: https://docs.docker.com/docker-for-mac/networking/#httphttps-proxy-support

In a Batch File you MUST use %% instead of % : (Type help for)

for /F "tokens=1,2,3" %%i in (myfile.txt) do call :process %%i %%j %%k
goto thenextstep
:process
set VAR1=%1
set VAR2=%2
set VAR3=%3
COMMANDS TO PROCESS INFORMATION
goto :EOF

What this does: The "do call :process %%i %%j %%k" at the end of the for command passes the information acquired in the for command from myfile.txt to the "process" 'subroutine'.

When you're using the for command in a batch program, you need to use double % signs for the variables.

The following lines pass those variables from the for command to the process 'sub routine' and allow you to process this information.

set VAR1=%1
 set VAR2=%2
 set VAR3=%3

I have some pretty advanced uses of this exact setup that I would be willing to share if further examples are needed. Add in your EOL or Delims as needed of course.

In the preferences section under Java -> Installed JREs click the Add button and navigate to the 1.5 JDK home folder. Then check that one in the list and it will become the default for all projects:

ids must be unique where as class can be applied to many things. In CSS, ids look like #elementID and class elements look like .someClass

In general, use id whenever you want to refer to a specific element and class when you have a number of things that are all alike. For instance, common id elements are things like header, footer, sidebar. Common class elements are things like highlight or external-link.

It's a good idea to read up on the cascade and understand the precedence assigned to various selectors: http://www.w3.org/TR/CSS2/cascade.html

The most basic precedence you should understand, however, is that id selectors take precedence over class selectors. If you had this:

<p id="intro" class="foo">Hello!</p>

and:

#intro { color: red }
.foo { color: blue }

The text would be red because the id selector takes precedence over the class selector.

I had same issue I could resolved issue with replace 'localhost' with IP which is '0.0.0.0'

I am using python3 and found out that you need to encode your string before you can pass it into stdin:

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
out, err = p.communicate(input='one\ntwo\nthree\nfour\nfive\nsix\n'.encode())
print(out)

Now, Angular 4 has email validator built-in https://github.com/angular/angular/blob/master/CHANGELOG.md#features-6 https://github.com/angular/angular/pull/13709

Just add email to the tag. For example

  <form #f="ngForm">
    <input type="email" ngModel name="email" required email>
    <button [disabled]="!f.valid">Submit</button>
    <p>Form State: {{f.valid?'VALID':'INVALID'}}</p>
  </form>

If you using RadAjaxManager then here is the code which helps:

RadAjaxManager1.ResponseScripts.Add("window.opener.location.href = '../CaseManagement/LCCase.aspx?" + caseId + "'; 
window.close();");

How about using a COUNT OVER (PARTITION BY {column to group by}) partitioning function in SQL Server?

For example, if you want to group product sales by ItemID and you want a count of each distinct ItemID, simply use:

SELECT
{columns you want} ,
COUNT(ItemID) OVER (PARTITION BY ItemID) as BandedItemCount ,
{more columns you want}... ,
FROM {MyTable}

If you use this approach, you can leave the GROUP BY out of the picture -- assuming you want to return the entire list (as you might do report banding where you need to know the entire count of items you are going to band without having to display the entire set of data, i.e. Reporting Services).

I know this is an older thread however I needed to write a function that returned the first blank row WITHIN a range. All of the code I found online actually searches the entire row (even the cells outside of the range) for a blank row. Data in ranges outside the search range was triggering a used row. This seemed to me to be a simple solution:

Function FirstBlankRow(ByVal rngToSearch As Range) As Long
   Dim R As Range
   Dim C As Range
   Dim RowIsBlank As Boolean

   For Each R In rngToSearch.Rows
      RowIsBlank = True
      For Each C In R.Cells
         If IsEmpty(C.Value) = False Then RowIsBlank = False
      Next C
      If RowIsBlank Then
         FirstBlankRow = R.Row
         Exit For
      End If
   Next R
End Function

Edit: As pointed out in comments (Mario Awad & Brock Hensley), use .find to get the children

$("form").each(function(){
    $(this).find(':input') //<-- Should return all input elements in that specific form.
});

forms also have an elements collection, sometimes this differs from children such as when the form tag is in a table and is not closed.

var summary = [];_x000D_
$('form').each(function () {_x000D_
    summary.push('Form ' + this.id + ' has ' + $(this).find(':input').length + ' child(ren).');_x000D_
    summary.push('Form ' + this.id + ' has ' + this.elements.length + ' form element(s).');_x000D_
});_x000D_
_x000D_
$('#results').html(summary.join('<br />'));

May be :input selector is what you want

$("form").each(function(){ $(':input', this)//<-- Should return all input elements in that specific form. });

$("form").each(function(){
    $(this).filter(':input') //<-- Should return all input elements in that specific form.
});

This is an old question, but since I was looking for full page load but for Spookyjs (that uses casperjs and phantomjs) and didn't find my solution, I made my own script for that, with the same approach as the user deemstone . What this approach does is, for a given quantity of time, if the page did not receive or started any request it will end the execution.

On casper.js file (if you installed it globally, the path would be something like /usr/local/lib/node_modules/casperjs/modules/casper.js) add the following lines:

At the top of the file with all the global vars:

var waitResponseInterval = 500
var reqResInterval = null
var reqResFinished = false
var resetTimeout = function() {}

Then inside function "createPage(casper)" just after "var page = require('webpage').create();" add the following code:

 resetTimeout = function() {
     if(reqResInterval)
         clearTimeout(reqResInterval)

     reqResInterval = setTimeout(function(){
         reqResFinished = true
         page.onLoadFinished("success")
     },waitResponseInterval)
 }
 resetTimeout()

Then inside "page.onResourceReceived = function onResourceReceived(resource) {" on the first line add:

 resetTimeout()

Do the same for "page.onResourceRequested = function onResourceRequested(requestData, request) {"

Finally, on "page.onLoadFinished = function onLoadFinished(status) {" on the first line add:

 if(!reqResFinished)
 {
      return
 }
 reqResFinished = false

And that's it, hope this one helps someone in trouble like I was. This solution is for casperjs but works directly for Spooky.

Good luck !

Seems like getTime is not function on above answer.

Date.parse(currentDate)/1000

The answer here is Oracle only. Here's a bit more sophisticated answer in all SQL:

Who has the best overall homework result (maximum sum of homework points)?

SELECT FIRST, LAST, SUM(POINTS) AS TOTAL
FROM STUDENTS S, RESULTS R
WHERE S.SID = R.SID AND R.CAT = 'H'
GROUP BY S.SID, FIRST, LAST
HAVING SUM(POINTS) >= ALL (SELECT SUM (POINTS)
FROM RESULTS
WHERE CAT = 'H'
GROUP BY SID)

And a more difficult example, which need some explanation, for which I don't have time atm:

Give the book (ISBN and title) that is most popular in 2008, i.e., which is borrowed most often in 2008.

SELECT X.ISBN, X.title, X.loans
FROM (SELECT Book.ISBN, Book.title, count(Loan.dateTimeOut) AS loans
FROM CatalogEntry Book
LEFT JOIN BookOnShelf Copy
ON Book.bookId = Copy.bookId
LEFT JOIN (SELECT * FROM Loan WHERE YEAR(Loan.dateTimeOut) = 2008) Loan 
ON Copy.copyId = Loan.copyId
GROUP BY Book.title) X
HAVING loans >= ALL (SELECT count(Loan.dateTimeOut) AS loans
FROM CatalogEntry Book
LEFT JOIN BookOnShelf Copy
ON Book.bookId = Copy.bookId
LEFT JOIN (SELECT * FROM Loan WHERE YEAR(Loan.dateTimeOut) = 2008) Loan 
ON Copy.copyId = Loan.copyId
GROUP BY Book.title);

Hope this helps (anyone).. :)

I'm not sure whether this could help, but I had a similar problem and I managed to solve it, by defining an apposite function:

def sor_dic_key(diction):
    lista = []
    diction2 = {}
    for x in diction:
        lista.append([x, diction[x]])
    lista.sort(key=lambda x: x[0])
    for l in lista:
        diction2[l[0]] = l[1]
    return diction2

This function returns another dictionary with the same keys and relative values, but sorted by its keys. Similarly, I defined a function that could sort a dictionary by its values. I just needed to use x[1] instead of x[0] in the lambda function. I find this second function mostly useless, but one never can tell!

Create you menu options the normal way see code below and add a global reference within the class to the menu

Menu mMenu;  // global reference within the class
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_tcktdetails, menu);
    mMenu=menu;  // assign the menu to the new menu item you just created 
    return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.action_cancelticket) {
        cancelTicket();

        return true;
    }

    return super.onOptionsItemSelected(item);
}

Now you can toggle your menu by running this code with a button or within a function

if(mMenu != null) {
                mMenu.findItem(R.id.action_cancelticket).setVisible(false);
            }

I found another way to take a input value of a UITextField and cast it to a float:

    var tempString:String?
    var myFloat:Float?

    @IBAction func ButtonWasClicked(_ sender: Any) {
       tempString = myUITextField.text
       myFloat = Float(tempString!)!
    }

If we have parameter like below in our POM XML

<version>${project.version}.${svn.version}</version>
  <packaging>war</packaging>

I run maven command line as follows :

mvn clean install package -Dproject.version=10 -Dsvn.version=1

One shortcoming of the accepted solution is that its output is very python specific. I.e. its raw json output cannot be observed by a human or loaded by another language (e.g. javascript). example:

db = {
        "a": [ 44, set((4,5,6)) ],
        "b": [ 55, set((4,3,2)) ]
        }

j = dumps(db, cls=PythonObjectEncoder)
print(j)

Will get you:

{"a": [44, {"_python_object": "gANjYnVpbHRpbnMKc2V0CnEAXXEBKEsESwVLBmWFcQJScQMu"}], "b": [55, {"_python_object": "gANjYnVpbHRpbnMKc2V0CnEAXXEBKEsCSwNLBGWFcQJScQMu"}]}

I can propose a solution which downgrades the set to a dict containing a list on the way out, and back to a set when loaded into python using the same encoder, therefore preserving observability and language agnosticism:

from decimal import Decimal
from base64 import b64encode, b64decode
from json import dumps, loads, JSONEncoder
import pickle

class PythonObjectEncoder(JSONEncoder):
    def default(self, obj):
        if isinstance(obj, (list, dict, str, int, float, bool, type(None))):
            return super().default(obj)
        elif isinstance(obj, set):
            return {"__set__": list(obj)}
        return {'_python_object': b64encode(pickle.dumps(obj)).decode('utf-8')}

def as_python_object(dct):
    if '__set__' in dct:
        return set(dct['__set__'])
    elif '_python_object' in dct:
        return pickle.loads(b64decode(dct['_python_object'].encode('utf-8')))
    return dct

db = {
        "a": [ 44, set((4,5,6)) ],
        "b": [ 55, set((4,3,2)) ]
        }

j = dumps(db, cls=PythonObjectEncoder)
print(j)
ob = loads(j)
print(ob["a"])

Which gets you:

{"a": [44, {"__set__": [4, 5, 6]}], "b": [55, {"__set__": [2, 3, 4]}]}
[44, {'__set__': [4, 5, 6]}]

Note that serializing a dictionary which has an element with a key "__set__" will break this mechanism. So __set__ has now become a reserved dict key. Obviously feel free to use another, more deeply obfuscated key.

This should be a short & simple copy & paste piece of code example of the above responses. Hopefully this helps.

#include <iostream>
using namespace std;

#define DBG_PRINT(x) do { std::printf("Line:%-4d" "  %15s = %-10d\n", __LINE__, #x, x); } while(0);

void F0(){ printf("Print F%d\n", 0); }
void F1(){ printf("Print F%d\n", 1); }
void F2(){ printf("Print F%d\n", 2); }
void F3(){ printf("Print F%d\n", 3); }
void F4(){ printf("Print F%d\n", 4); }
void (*fArrVoid[N_FUNC])() = {F0, F1, F2, F3, F4};

int Sum(int a, int b){ return(a+b); }
int Sub(int a, int b){ return(a-b); }
int Mul(int a, int b){ return(a*b); }
int Div(int a, int b){ return(a/b); }
int (*fArrArgs[4])(int a, int b) = {Sum, Sub, Mul, Div};

int main(){
    for(int i = 0; i < 5; i++)  (*fArrVoid[i])();
    printf("\n");

    DBG_PRINT((*fArrArgs[0])(3,2))
    DBG_PRINT((*fArrArgs[1])(3,2))
    DBG_PRINT((*fArrArgs[2])(3,2))
    DBG_PRINT((*fArrArgs[3])(3,2))

    return(0);
}

I had a similar problem. I was working on a project where I did not control the web.xml configuration file, so I could not use the changes suggested about altering the version. Of course the project was not using JSF so this was especially annoying for me.

I found that there is a really simple fix. Go to Preferences > Maven > Java EE Itegration and uncheck the "JSF Configurator" box.

I did this in a fresh workspace before importing the project again, but it may work equally as well on an existing project ... not sure.

(See here also for my C++11 answer)

In order to parse a C++ program, the compiler needs to know whether certain names are types or not. The following example demonstrates that:

t * f;

How should this be parsed? For many languages a compiler doesn't need to know the meaning of a name in order to parse and basically know what action a line of code does. In C++, the above however can yield vastly different interpretations depending on what t means. If it's a type, then it will be a declaration of a pointer f. However if it's not a type, it will be a multiplication. So the C++ Standard says at paragraph (3/7):

Some names denote types or templates. In general, whenever a name is encountered it is necessary to determine whether that name denotes one of these entities before continuing to parse the program that contains it. The process that determines this is called name lookup.

How will the compiler find out what a name t::x refers to, if t refers to a template type parameter? x could be a static int data member that could be multiplied or could equally well be a nested class or typedef that could yield to a declaration. If a name has this property - that it can't be looked up until the actual template arguments are known - then it's called a dependent name (it "depends" on the template parameters).

You might recommend to just wait till the user instantiates the template:

Let's wait until the user instantiates the template, and then later find out the real meaning of t::x * f;.

This will work and actually is allowed by the Standard as a possible implementation approach. These compilers basically copy the template's text into an internal buffer, and only when an instantiation is needed, they parse the template and possibly detect errors in the definition. But instead of bothering the template's users (poor colleagues!) with errors made by a template's author, other implementations choose to check templates early on and give errors in the definition as soon as possible, before an instantiation even takes place.

So there has to be a way to tell the compiler that certain names are types and that certain names aren't.

The "typename" keyword

The answer is: We decide how the compiler should parse this. If t::x is a dependent name, then we need to prefix it by typename to tell the compiler to parse it in a certain way. The Standard says at (14.6/2):

A name used in a template declaration or definition and that is dependent on a template-parameter is assumed not to name a type unless the applicable name lookup finds a type name or the name is qualified by the keyword typename.

There are many names for which typename is not necessary, because the compiler can, with the applicable name lookup in the template definition, figure out how to parse a construct itself - for example with T *f;, when T is a type template parameter. But for t::x * f; to be a declaration, it must be written as typename t::x *f;. If you omit the keyword and the name is taken to be a non-type, but when instantiation finds it denotes a type, the usual error messages are emitted by the compiler. Sometimes, the error consequently is given at definition time:

// t::x is taken as non-type, but as an expression the following misses an
// operator between the two names or a semicolon separating them.
t::x f;

The syntax allows typename only before qualified names - it is therefor taken as granted that unqualified names are always known to refer to types if they do so.

A similar gotcha exists for names that denote templates, as hinted at by the introductory text.

The "template" keyword

Remember the initial quote above and how the Standard requires special handling for templates as well? Let's take the following innocent-looking example:

boost::function< int() > f;

It might look obvious to a human reader. Not so for the compiler. Imagine the following arbitrary definition of boost::function and f:

namespace boost { int function = 0; }
int main() { 
  int f = 0;
  boost::function< int() > f; 
}

That's actually a valid expression! It uses the less-than operator to compare boost::function against zero (int()), and then uses the greater-than operator to compare the resulting bool against f. However as you might well know, boost::function in real life is a template, so the compiler knows (14.2/3):

After name lookup (3.4) finds that a name is a template-name, if this name is followed by a <, the < is always taken as the beginning of a template-argument-list and never as a name followed by the less-than operator.

Now we are back to the same problem as with typename. What if we can't know yet whether the name is a template when parsing the code? We will need to insert template immediately before the template name, as specified by 14.2/4. This looks like:

t::template f<int>(); // call a function template

Template names can not only occur after a :: but also after a -> or . in a class member access. You need to insert the keyword there too:

this->template f<int>(); // call a function template

Dependencies

For the people that have thick Standardese books on their shelf and that want to know what exactly I was talking about, I'll talk a bit about how this is specified in the Standard.

In template declarations some constructs have different meanings depending on what template arguments you use to instantiate the template: Expressions may have different types or values, variables may have different types or function calls might end up calling different functions. Such constructs are generally said to depend on template parameters.

The Standard defines precisely the rules by whether a construct is dependent or not. It separates them into logically different groups: One catches types, another catches expressions. Expressions may depend by their value and/or their type. So we have, with typical examples appended:

• Dependent types (e.g: a type template parameter T)
• Value-dependent expressions (e.g: a non-type template parameter N)
• Type-dependent expressions (e.g: a cast to a type template parameter (T)0)

Most of the rules are intuitive and are built up recursively: For example, a type constructed as T[N] is a dependent type if N is a value-dependent expression or T is a dependent type. The details of this can be read in section (14.6.2/1) for dependent types, (14.6.2.2) for type-dependent expressions and (14.6.2.3) for value-dependent expressions.

Dependent names

The Standard is a bit unclear about what exactly is a dependent name. On a simple read (you know, the principle of least surprise), all it defines as a dependent name is the special case for function names below. But since clearly T::x also needs to be looked up in the instantiation context, it also needs to be a dependent name (fortunately, as of mid C++14 the committee has started to look into how to fix this confusing definition).

To avoid this problem, I have resorted to a simple interpretation of the Standard text. Of all the constructs that denote dependent types or expressions, a subset of them represent names. Those names are therefore "dependent names". A name can take different forms - the Standard says:

A name is a use of an identifier (2.11), operator-function-id (13.5), conversion-function-id (12.3.2), or template-id (14.2) that denotes an entity or label (6.6.4, 6.1)

An identifier is just a plain sequence of characters / digits, while the next two are the operator + and operator type form. The last form is template-name <argument list>. All these are names, and by conventional use in the Standard, a name can also include qualifiers that say what namespace or class a name should be looked up in.

A value dependent expression 1 + N is not a name, but N is. The subset of all dependent constructs that are names is called dependent name. Function names, however, may have different meaning in different instantiations of a template, but unfortunately are not caught by this general rule.

Dependent function names

Not primarily a concern of this article, but still worth mentioning: Function names are an exception that are handled separately. An identifier function name is dependent not by itself, but by the type dependent argument expressions used in a call. In the example f((T)0), f is a dependent name. In the Standard, this is specified at (14.6.2/1).

Additional notes and examples

In enough cases we need both of typename and template. Your code should look like the following

template <typename T, typename Tail>
struct UnionNode : public Tail {
    // ...
    template<typename U> struct inUnion {
        typedef typename Tail::template inUnion<U> dummy;
    };
    // ...
};

The keyword template doesn't always have to appear in the last part of a name. It can appear in the middle before a class name that's used as a scope, like in the following example

typename t::template iterator<int>::value_type v;

In some cases, the keywords are forbidden, as detailed below

• On the name of a dependent base class you are not allowed to write typename. It's assumed that the name given is a class type name. This is true for both names in the base-class list and the constructor initializer list:

   template <typename T>
   struct derive_from_Has_type : /* typename */ SomeBase<T>::type 
   { };
  

• In using-declarations it's not possible to use template after the last ::, and the C++ committee said not to work on a solution.

   template <typename T>
   struct derive_from_Has_type : SomeBase<T> {
      using SomeBase<T>::template type; // error
      using typename SomeBase<T>::type; // typename *is* allowed
   };
  

This is an old post, but if anyone comes up with this problem, i post what solved my problem:

I was trying to add the Action Bar Sherlock to my proyect when i get the error:

Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Holo.ActionBar'.

I turns out that the action bar sherlock proyect and my proyect had differents minSdkVersion and targetSdkVersion. Changing that parameters to match in both proyect solved my problem.

<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="17"/>

I found the default JS date formatting didn't work.

So I used toLocaleString with options

const event = new Date();
const options = { dateStyle: 'short' };
const date = event.toLocaleString('en', options);

to get: DD/MM/YYYY format

See docs for more formatting options: https://www.w3schools.com/jsref/jsref_tolocalestring.asp

You might consider storing the time as a DateTime, and in UTC. I typically use DateTime instead of Timestamp because of the fact that MySql converts dates to UTC and back to local time when storing and retrieving the data. I'd rather keep any of that kind of logic in one place (Business layer). I'm sure there are other situations where using Timestamp is preferable though.

2.0 Compatible Answer: In Tensorflow 2.x (2.1), you can get the dimensions (shape) of the tensor as integer values, as shown in the Code below:

Method 1 (using tf.shape):

import tensorflow as tf
c = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
Shape = c.shape.as_list()
print(Shape)   # [2,3]

Method 2 (using tf.get_shape()):

import tensorflow as tf
c = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
Shape = c.get_shape().as_list()
print(Shape)   # [2,3]

To copy with indexes and triggers do these 2 queries:

CREATE TABLE newtable LIKE oldtable; 
INSERT INTO newtable SELECT * FROM oldtable;

To copy just structure and data use this one:

CREATE TABLE tbl_new AS SELECT * FROM tbl_old;

Resolved this issue for vue, by adding to the options an id: 'alertBox' so now every modal container has its parent set to something like alertBox__id0whatver which can easily be changed with css:

div[id*="alertBox"] { background: red; }

(meaning if id name contains ( *= ) 'alertBox' it will be applied.

Try this:

If you have many factor variables, you can use select_if funtion. install the dplyr packages. There are many function that separates data by satisfying a condition. you can set the conditions.

Use like this.

I tried to resolve with the suggested answer and still ran into some issues...

This was a solution to my problem:

ARG APP_EXE="AppName.exe"
ENV _EXE=${APP_EXE}

# Build a shell script because the ENTRYPOINT command doesn't like using ENV
RUN echo "#!/bin/bash \n mono ${_EXE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh

# Run the generated shell script.
ENTRYPOINT ["./entrypoint.sh"]

Specifically targeting your problem:

RUN echo "#!/bin/bash \n ./greeting --message ${ADDRESSEE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]

I often use them to tell the default target not to fire.

superclean: clean andsomethingelse

blah: superclean

clean:
   @echo clean

%:
   @echo catcher $@

.PHONY: superclean

Without PHONY, make superclean would fire clean, andsomethingelse, and catcher superclean; but with PHONY, make superclean won't fire the catcher superclean.

We don't have to worry about telling make the clean target is PHONY, because it isn't completely phony. Though it never produces the clean file, it has commands to fire so make will think it's a final target.

However, the superclean target really is phony, so make will try to stack it up with anything else that provides deps for the superclean target — this includes other superclean targets and the % target.

Note that we don't say anything at all about andsomethingelse or blah, so they clearly go to the catcher.

The output looks something like this:

$ make clean
clean

$ make superclean
clean
catcher andsomethingelse

$ make blah 
clean
catcher andsomethingelse
catcher blah

    db      0x55,0x56,0x57      ; three bytes in succession
    db      'a',0x55            ; character constants are OK
    db      'hello',13,10,'$'   ; so are string constants

    dw      'AB'                ; 0x41 0x42 (character constant)
    dw      'ABC'               ; 0x41 0x42 0x43 0x00 (string)

    do      0x112233445566778899aabbccddeeff00 ; same as previous
    dd      1.234567e20         ; floating-point constant
    dq      1.234567e20         ; double-precision float
    dt      1.234567e20         ; extended-precision float

DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.

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

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

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

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

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))
{
    grfx.DrawImage(newImage, x, y)
}

Graphics is in the namespace System.Drawing

MATLAB, as mentioned by others, is great at matrix manipulation, and was originally built as an extension of the well-known BLAS and LAPACK libraries used for linear algebra. It interfaces well with other languages like Java, and is well favored by engineering and scientific companies for its well developed and documented libraries. From what I know of Python and NumPy, while they share many of the fundamental capabilities of MATLAB, they don't have the full breadth and depth of capabilities with their libraries.

Personally, I use MATLAB because that's what I learned in my internship, that's what I used in grad school, and that's what I used in my first job. I don't have anything against Python (or any other language). It's just what I'm used too.

Also, there is another free version in addition to scilab mentioned by @Jim C from gnu called Octave.

By Default angular return responseType as Json, but we can configure below types according to your requirement.

responseType: 'arraybuffer'|'blob'|'json'|'text'

Ex:

this.http.post(
    'http://localhost:8080/order/addtocart', 
    { dealerId: 13, createdBy: "-1", productId, quantity }, 
    { headers, responseType: 'text'});

The difference in whether you have to instantiate your @InjectMocks annotated field is in the version of Mockito, not in whether you use the MockitoJunitRunner or MockitoAnnotations.initMocks. In 1.9, which will also handle some constructor injection of your @Mock fields, it will do the instantiation for you. In earlier versions, you have to instantiate it yourself.

This is how I do unit testing of my Spring beans. There is no problem. People run into confusion when they want to use Spring configuration files to actually do the injection of the mocks, which is crossing up the point of unit tests and integration tests.

And of course the unit under test is an Impl. You need to test a real concrete thing, right? Even if you declared it as an interface you would have to instantiate the real thing to test it. Now, you could get into spies, which are stub/mock wrappers around real objects, but that should be for corner cases.

$foo = Bar::getBeers(); $foo = $foo->toArray();

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

This answer no longer works, and I cannot come up with anything better then the other answers (see below) listed here. Please review and up-vote them.

Convert.ToInt64("1100.25")

Method signature from MSDN:

public static long ToInt64(
    string value
)

You have to allocate the buffer with mallock, and give the read write the pointer to it.

#include <unistd.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int main(){
    ssize_t nrd;
    int fd; 
    int fd1;

    char* buffer = malloc(100*sizeof(char));
    fd = open("bli.txt", O_RDONLY);
    fd1 = open("bla.txt", O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
    while (nrd = read(fd,buffer,sizeof(buffer))) {
        write(fd1,buffer,nrd);
    }   

    close(fd);
    close(fd1);
    free(buffer);
    return 0;
}

Make sure that the rad file exists and contains something. It's not perfect but it works.

value = value.setScale(2, RoundingMode.CEILING)

On Debian we use the start-stop-daemon utility, which handles pid-files, changing the user, putting the daemon into background and much more.

I'm not familiar with RedHat, but the daemon utility that you are already using (which is defined in /etc/init.d/functions, btw.) is mentioned everywhere as the equivalent to start-stop-daemon, so either it can also change the uid of your program, or the way you do it is already the correct one.

If you look around the net, there are several ready-made wrappers that you can use. Some may even be already packaged in RedHat. Have a look at daemonize, for example.

Localstorage is designed to be accessible by javascript, so it doesn't provide any XSS protection. As mentioned in other answers, there is a bunch of possible ways to do an XSS attack, from which localstorage is not protected by default.

However, cookies have security flags which protect from XSS and CSRF attacks. HttpOnly flag prevents client side javascript from accessing the cookie, Secure flag only allows the browser to transfer the cookie through ssl, and SameSite flag ensures that the cookie is sent only to the origin. Although I just checked and SameSite is currently supported only in Opera and Chrome, so to protect from CSRF it's better to use other strategies. For example, sending an encrypted token in another cookie with some public user data.

So cookies are a more secure choice for storing authentication data.

It's easy maybe you have error in the configuration.

For Example: Manifest.xml

But in my configuration have for default Activity .Splash

you need check this configuration and the file Manifest.xml

Good Luck

Edit: I missed the multi-dimensional aspect of this question, so I'm leaving this here in case it helps people compare one-dimensional arrays

It's an old question, but I was having issues with the speed of using .sort() or sortBy(), so I used this instead:

function arraysContainSameStrings(array1: string[], array2: string[]): boolean {
  return (
    array1.length === array2.length &&
    array1.every((str) => array2.includes(str)) &&
    array2.every((str) => array1.includes(str))
  )
}

It was intended to fail fast, and for my purposes works fine.

Just be aware also that catalina.out can be renamed - it can be set in /bin/catalina.sh with the CATALINA_OUT environment variable.

Mongoose now supports the timestamps in schema.

const item = new Schema(
  {
    id: {
      type: String,
      required: true,
    },
  { timestamps: true },
);

This will add the createdAt and updatedAt fields on each record create.

Timestamp interface has fields

  interface SchemaTimestampsConfig {
    createdAt?: boolean | string;
    updatedAt?: boolean | string;
    currentTime?: () => (Date | number);
  }

This would help us to choose which fields we want and overwrite the date format.
