Since you're scanning the whole string anyway you can build a full character count and do any number of lookups, all for the same big-Oh cost (n):

public static Map<Character,Integer> getCharFreq(String s) {
  Map<Character,Integer> charFreq = new HashMap<Character,Integer>();
  if (s != null) {
    for (Character c : s.toCharArray()) {
      Integer count = charFreq.get(c);
      int newCount = (count==null ? 1 : count+1);
      charFreq.put(c, newCount);
    }
  }
  return charFreq;
}

// ...
String s = "abdsd3$asda$asasdd$sadas";
Map counts = getCharFreq(s);
counts.get('$'); // => 3
counts.get('a'); // => 7
counts.get('s'); // => 6

You are probably trying to create nested directories. Assuming foo does not exist, you will receive no such file or directory error for:

Dir.mkdir 'foo/bar'
# => Errno::ENOENT: No such file or directory - 'foo/bar'

To create nested directories at once, FileUtils is needed:

require 'fileutils'
FileUtils.mkdir_p 'foo/bar'
# => ["foo/bar"]

Edit2: you do not have to use FileUtils, you may do system call (update from @mu is too short comment):

> system 'mkdir', '-p', 'foo/bar' # worse version: system 'mkdir -p "foo/bar"'
=> true

But that seems (at least to me) as worse approach as you are using external 'tool' which may be unavailable on some systems (although I can hardly imagine system without mkdir, but who knows).

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

PackageManager m = getPackageManager();
String s = getPackageName();
PackageInfo p = m.getPackageInfo(s, 0);
s = p.applicationInfo.dataDir;

If eclipse worries about an uncaught NameNotFoundException, you can use:

PackageManager m = getPackageManager();
String s = getPackageName();
try {
    PackageInfo p = m.getPackageInfo(s, 0);
    s = p.applicationInfo.dataDir;
} catch (PackageManager.NameNotFoundException e) {
    Log.w("yourtag", "Error Package name not found ", e);
}

Your data types are mismatched when you are retrieving the field values. Check your code and ensure that for each field that you are retrieving that the java object matches that type. For example, retrieving a date into and int. If you are doing a select * then it is possible a change in the fields of the table has happened causing this error to occur. Your SQL should only select the fields you specifically want in order to avoid this error.

Hope this helps.

None of the answers above helped me on Windows 10 when testing locally on

https://localhost:<port>.

However I found this page, indicating another flag to pass:

https://www.chromium.org/blink/serviceworker/service-worker-faq

If you want to test on https://localhost with a self-signed certificate, do:

$ ./chrome --allow-insecure-localhost https://localhost

That did not get rid of the red warning, but it did enable me to use https-only feature like service workers and web push notifications.

To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

COPY ./files/. /files/

Please have a look at substr based function that can change formats

function phone(string $in): string
{
    $FORMAT_PHONE = [1,3,3,4];
    $result =[];
    $position = 0;
    foreach ($FORMAT_PHONE as $key => $item){
        $result[] = substr($in, $position, $item);
        $position += $item;
    }
    return '+'.implode('-',$result);
}

The main issue is that the inner query cannot be related to your where clause on the outer update statement, because the where filter applies first to the table being updated before the inner subquery even executes. The typical way to handle a situation like this is a multi-table update.

Update
  Competition as C
  inner join (
    select CompetitionId, count(*) as NumberOfTeams
    from PicksPoints as p
    where UserCompetitionID is not NULL
    group by CompetitionID
  ) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = A.NumberOfTeams

This it the best way to calculate the size of a directory. Only other way would still use recursion but be a bit easier to use and isn't as flexible.

float folderSize = 0.0f;
FileInfo[] files = Directory.GetFiles(folder, "*", SearchOption.AllDirectories);
foreach(FileInfo file in files) folderSize += file.Length;

Linux minimal runnable examples with disassembly analysis

Since this is an implementation detail not specified by standards, let's just have a look at what the compiler is doing on a particular implementation.

In this answer, I will either link to specific answers that do the analysis, or provide the analysis directly here, and summarize all results here.

All of those are in various Ubuntu / GCC versions, and the outcomes are likely pretty stable across versions, but if we find any variations let's specify more precise versions.

Local variable inside a function

Be it main or any other function:

void f(void) {
    int my_local_var;
}

As shown at: What does <value optimized out> mean in gdb?

• -O0: stack
• -O3: registers if they don't spill, stack otherwise

For motivation on why the stack exists see: What is the function of the push / pop instructions used on registers in x86 assembly?

Global variables and static function variables

/* BSS */
int my_global_implicit;
int my_global_implicit_explicit_0 = 0;

/* DATA */
int my_global_implicit_explicit_1 = 1;

void f(void) {
    /* BSS */
    static int my_static_local_var_implicit;
    static int my_static_local_var_explicit_0 = 0;

    /* DATA */
    static int my_static_local_var_explicit_1 = 1;
}

• if initialized to 0 or not initialized (and therefore implicitly initialized to 0): .bss section, see also: Why is the .bss segment required?
• otherwise: .data section

char * and char c[]

As shown at: Where are static variables stored in C and C++?

void f(void) {
    /* RODATA / TEXT */
    char *a = "abc";

    /* Stack. */
    char b[] = "abc";
    char c[] = {'a', 'b', 'c', '\0'};
}

TODO will very large string literals also be put on the stack? Or .data? Or does compilation fail?

Function arguments

void f(int i, int j);

Must go through the relevant calling convention, e.g.: https://en.wikipedia.org/wiki/X86_calling_conventions for X86, which specifies either specific registers or stack locations for each variable.

Then as shown at What does <value optimized out> mean in gdb?, -O0 then slurps everything into the stack, while -O3 tries to use registers as much as possible.

If the function gets inlined however, they are treated just like regular locals.

const

I believe that it makes no difference because you can typecast it away.

Conversely, if the compiler is able to determine that some data is never written to, it could in theory place it in .rodata even if not const.

TODO analysis.

Pointers

They are variables (that contain addresses, which are numbers), so same as all the rest :-)

malloc

The question does not make much sense for malloc, since malloc is a function, and in:

int *i = malloc(sizeof(int));

*i is a variable that contains an address, so it falls on the above case.

As for how malloc works internally, when you call it the Linux kernel marks certain addresses as writable on its internal data structures, and when they are touched by the program initially, a fault happens and the kernel enables the page tables, which lets the access happen without segfaul: How does x86 paging work?

Note however that this is basically exactly what the exec syscall does under the hood when you try to run an executable: it marks pages it wants to load to, and writes the program there, see also: How does kernel get an executable binary file running under linux? Except that exec has some extra limitations on where to load to (e.g. is the code is not relocatable).

The exact syscall used for malloc is mmap in modern 2020 implementations, and in the past brk was used: Does malloc() use brk() or mmap()?

Dynamic libraries

Basically get mmaped to memory: https://unix.stackexchange.com/questions/226524/what-system-call-is-used-to-load-libraries-in-linux/462710#462710

envinroment variables and main's argv

Above initial stack: https://unix.stackexchange.com/questions/75939/where-is-the-environment-string-actual-stored TODO why not in .data?

API Documentation

According to the Android developers guide for android.hardware.Camera, they state:

We recommend using the new android.hardware.camera2 API for new applications.

On the information page about android.hardware.camera2, (linked above), it is stated:

The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.

The problem

When you check that documentation you'll find that the implementation of these 2 Camera API's are very different.

For example getting camera orientation on android.hardware.camera

@Override
public int getOrientation(final int cameraId) {
    Camera.CameraInfo info = new Camera.CameraInfo();
    Camera.getCameraInfo(cameraId, info);
    return info.orientation;
}

Versus android.hardware.camera2

@Override
public int getOrientation(final int cameraId) {
    try {
        CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        String[] cameraIds = manager.getCameraIdList();
        CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
        return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
    } catch (CameraAccessException e) {
        // TODO handle error properly or pass it on
        return 0;
    }
}

This makes it hard to switch from one to another and write code that can handle both implementations.

Note that in this single code example I already had to work around the fact that the olde camera API works with int primitives for camera IDs while the new one works with String objects. For this example I quickly fixed that by using the int as an index in the new API. If the camera's returned aren't always in the same order this will already cause issues. Alternative approach is to work with String objects and String representation of the old int cameraIDs which is probably safer.

One away around

Now to work around this huge difference you can implement an interface first and reference that interface in your code.

Here I'll list some code for that interface and the 2 implementations. You can limit the implementation to what you actually use of the camera API to limit the amount of work.

In the next section I'll quickly explain how to load one or another.

The interface wrapping all you need, to limit this example I only have 2 methods here.

public interface CameraSupport {
    CameraSupport open(int cameraId);
    int getOrientation(int cameraId);
}

Now have a class for the old camera hardware api:

@SuppressWarnings("deprecation")
public class CameraOld implements CameraSupport {

    private Camera camera;

    @Override
    public CameraSupport open(final int cameraId) {
        this.camera = Camera.open(cameraId);
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
       Camera.CameraInfo info = new Camera.CameraInfo();
       Camera.getCameraInfo(cameraId, info);
       return info.orientation;
    }
}

And another one for the new hardware api:

public class CameraNew implements CameraSupport {

    private CameraDevice camera;
    private CameraManager manager;

    public CameraNew(final Context context) {
        this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
    }

    @Override
    public CameraSupport open(final int cameraId) {
        try {
            String[] cameraIds = manager.getCameraIdList();
            manager.openCamera(cameraIds[cameraId], new CameraDevice.StateCallback() {
                @Override
                public void onOpened(CameraDevice camera) {
                    CameraNew.this.camera = camera;
                }

                @Override
                public void onDisconnected(CameraDevice camera) {
                    CameraNew.this.camera = camera;
                    // TODO handle
                }

                @Override
                public void onError(CameraDevice camera, int error) {
                    CameraNew.this.camera = camera;
                    // TODO handle
                }
            }, null);
        } catch (Exception e) {
            // TODO handle
        }
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
        try {
            String[] cameraIds = manager.getCameraIdList();
            CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
            return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
        } catch (CameraAccessException e) {
            // TODO handle
            return 0;
        }
    }
}

Loading the proper API

Now to load either your CameraOld or CameraNew class you'll have to check the API level since CameraNew is only available from api level 21.

If you have dependency injection set up already you can do so in your module when providing the CameraSupport implementation. Example:

@Module public class CameraModule {

    @Provides
    CameraSupport provideCameraSupport(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            return new CameraNew(context);
        } else {
            return new CameraOld();
        }
    } 
}

If you don't use DI you can just make a utility or use Factory pattern to create the proper one. Important part is that the API level is checked.

Very simple ! Here is my suggestion :

If you want to select dataframes in your workspace, try this :

Filter(function(x) is.data.frame(get(x)) , ls())

or

ls()[sapply(ls(), function(x) is.data.frame(get(x)))]

all these will give the same result.

You can change is.data.frame to check other types of variables like is.function

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

The name reflection is used to describe code which is able to inspect other code in the same system (or itself).

For example, say you have an object of an unknown type in Java, and you would like to call a 'doSomething' method on it if one exists. Java's static typing system isn't really designed to support this unless the object conforms to a known interface, but using reflection, your code can look at the object and find out if it has a method called 'doSomething' and then call it if you want to.

So, to give you a code example of this in Java (imagine the object in question is foo) :

Method method = foo.getClass().getMethod("doSomething", null);
method.invoke(foo, null);

One very common use case in Java is the usage with annotations. JUnit 4, for example, will use reflection to look through your classes for methods tagged with the @Test annotation, and will then call them when running the unit test.

There are some good reflection examples to get you started at http://docs.oracle.com/javase/tutorial/reflect/index.html

And finally, yes, the concepts are pretty much similar in other statically typed languages which support reflection (like C#). In dynamically typed languages, the use case described above is less necessary (since the compiler will allow any method to be called on any object, failing at runtime if it does not exist), but the second case of looking for methods which are marked or work in a certain way is still common.

Update from a comment:

The ability to inspect the code in the system and see object types is not reflection, but rather Type Introspection. Reflection is then the ability to make modifications at runtime by making use of introspection. The distinction is necessary here as some languages support introspection, but do not support reflection. One such example is C++

You can use a subquery:

SELECT *
FROM terms
WHERE id IN (SELECT term_id FROM terms_relation WHERE taxonomy='categ');

and if you need to show all columns from both tables:

SELECT t.*, tr.*
FROM terms t, terms_relation tr
WHERE t.id = tr.term_id
AND tr.taxonomy='categ'

Well, I am new in HTML, CSS and in Java but I tried my way which worked for me in all browsers. I have used JS instead of CSS which doesn't work with some browsers.

First of all I have given id="myHR" to HR element and used it in Java Script.
Here is the Code.

x = document.getElementById("myHR");
y = x.style.width = "600px";
y = x.style.color = "white";
y = x.style.height = "2px";
y = x.style.border = "none";
y = x.style.backgroundColor = "lightgrey";

1. Go in Github an create a repo for your new code.
2. Use the new https or ssh url in Eclise when you are doing the push to upstream;

You can use the multiprocessing module. For this case I might use a processing pool:

from multiprocessing import Pool
pool = Pool()
result1 = pool.apply_async(solve1, [A])    # evaluate "solve1(A)" asynchronously
result2 = pool.apply_async(solve2, [B])    # evaluate "solve2(B)" asynchronously
answer1 = result1.get(timeout=10)
answer2 = result2.get(timeout=10)

This will spawn processes that can do generic work for you. Since we did not pass processes, it will spawn one process for each CPU core on your machine. Each CPU core can execute one process simultaneously.

If you want to map a list to a single function you would do this:

args = [A, B]
results = pool.map(solve1, args)

Don't use threads because the GIL locks any operations on python objects.

Here is a complete sample to show RecyclerView with 2 types, the view type decide by the object

This will also help in importing files in from different folders. Try extends method to inherit the classes in that file and reuse the functions

Easy done:

(?<=\[)(.*?)(?=\])

Technically that's using lookaheads and lookbehinds. See Lookahead and Lookbehind Zero-Width Assertions. The pattern consists of:

• is preceded by a [ that is not captured (lookbehind);
• a non-greedy captured group. It's non-greedy to stop at the first ]; and
• is followed by a ] that is not captured (lookahead).

Alternatively you can just capture what's between the square brackets:

\[(.*?)\]

and return the first captured group instead of the entire match.

Here is a good example -

ul li{
    list-style-type: disc;
    list-style-position: inside;
    padding: 10px 0 10px 20px;
    text-indent: -1em;
}

Working Demo: http://jsfiddle.net/d9VNk/

Use following extension if you don't want to calculate too much:

func scrollSubviewToBeVisible(subview: UIView, animated: Bool) {
    let visibleFrame = UIEdgeInsetsInsetRect(self.bounds, self.contentInset)
    let subviewFrame = subview.convertRect(subview.bounds, toView: self)
    if (!CGRectContainsRect(visibleFrame, subviewFrame)) {
        self.scrollRectToVisible(subviewFrame, animated: animated)
    }
}

And maybe you want keep your UITextField always visible:

func textViewDidChange(textView: UITextView) {
    self.scrollView?.scrollSubviewToBeVisible(textView, animated: false)
}

You can use Core Graphics to draw the gradient, as pointed to in Mike's response. As a more detailed example, you could create a UIView subclass to use as a background for your UILabel. In that UIView subclass, override the drawRect: method and insert code similar to the following:

- (void)drawRect:(CGRect)rect 
{
    CGContextRef currentContext = UIGraphicsGetCurrentContext();

    CGGradientRef glossGradient;
    CGColorSpaceRef rgbColorspace;
    size_t num_locations = 2;
    CGFloat locations[2] = { 0.0, 1.0 };
    CGFloat components[8] = { 1.0, 1.0, 1.0, 0.35,  // Start color
         1.0, 1.0, 1.0, 0.06 }; // End color

    rgbColorspace = CGColorSpaceCreateDeviceRGB();
    glossGradient = CGGradientCreateWithColorComponents(rgbColorspace, components, locations, num_locations);

    CGRect currentBounds = self.bounds;
    CGPoint topCenter = CGPointMake(CGRectGetMidX(currentBounds), 0.0f);
    CGPoint midCenter = CGPointMake(CGRectGetMidX(currentBounds), CGRectGetMidY(currentBounds));
    CGContextDrawLinearGradient(currentContext, glossGradient, topCenter, midCenter, 0);

    CGGradientRelease(glossGradient);
    CGColorSpaceRelease(rgbColorspace); 
}

This particular example creates a white, glossy-style gradient that is drawn from the top of the UIView to its vertical center. You can set the UIView's backgroundColor to whatever you like and this gloss will be drawn on top of that color. You can also draw a radial gradient using the CGContextDrawRadialGradient function.

You just need to size this UIView appropriately and add your UILabel as a subview of it to get the effect you desire.

EDIT (4/23/2009): Per St3fan's suggestion, I have replaced the view's frame with its bounds in the code. This corrects for the case when the view's origin is not (0,0).

To add with @msandiford answer, as most of the times when a file tree is walked u may want to execute a function as a directory or any particular file is visited. If u are reluctant to using streams. The following methods overridden can be implemented

Files.walkFileTree(Paths.get(Krawl.INDEXPATH), EnumSet.of(FileVisitOption.FOLLOW_LINKS), Integer.MAX_VALUE,
    new SimpleFileVisitor<Path>() {
        @Override
        public FileVisitResult preVisitDirectory(Path dir, BasicFileAttributes attrs)
                throws IOException {
                // Do someting before directory visit
                return FileVisitResult.CONTINUE;
        }
        @Override
        public FileVisitResult visitFile(Path file, BasicFileAttributes attrs)
                throws IOException {
                // Do something when a file is visited
                return FileVisitResult.CONTINUE;
        }
        @Override
        public FileVisitResult postVisitDirectory(Path dir, IOException exc)
                throws IOException {
                // Do Something after directory visit 
                return FileVisitResult.CONTINUE;
        }
});

I noticed that when it's set to false, I'm able to see the value of an item using the debugger. When it was set to true, I was getting an error - item.FullName.GetValue The embedded interop type 'FullName' does not contain a definition for 'QBFC11Lib.IItemInventoryRet' since it was not used in the compiled assembly. Consider casting to object or changing the 'Embed Interop Types' property to true.

Android has @VisibleForTesting annotation from android.support.annotation package.

The @VisibleForTesting annotation indicates that an annotated method is more visible than normally necessary to make the method testable. This annotation has an optional otherwise argument that lets you designate what the visibility of the method should have been if not for the need to make it visible for testing. Lint uses the otherwise argument to enforce the intended visibility.

On the practice it means that you should make a method open for testing and the @VisibleForTesting annotation will show a warning.

For example

package com.mypackage;

public class ClassA {

    @VisibleForTesting(otherwise = VisibleForTesting.PRIVATE)
    static void myMethod() {

    }
}

And when you call ClassA.myMethod() within the same package(com.mypackage) you will see the warning.

Most likely you have incorrect compiler options imported from Maven here:

Also check project and module bytecode (target) version settings outlined on the screenshot.

Other places where the source language level is configured:

• Project Structure | Project

• Project Structure | Modules (check every module) | Sources

Maven default language level is 1.5 (5.0), you will see this version as the Module language level on the screenshot above.

This can be changed using maven-compiler-plugin configuration inside pom.xml:

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

or

<project>
  [...]
  <properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
  </properties>
  [...]
</project>

IntelliJ IDEA will respect this setting after you Reimport the Maven project in the Maven Projects tool window:

Ok, I know there is an accepted answer but… for more special cases you also could use this one:

array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);

Or in a more un-complex way:

function printItem($n){
    echo $n['filename'];
    echo $n['filepath'];
}

array_map('printItem', $array);

This will allow you to manipulate the data in an easier way.

For a general solution you can use the Column Comparator. The code to use the class would be:

Arrays.sort(myArr, new ColumnComparator(0));

In Python, you'd do this with a default argument.

class A:

    def stackoverflow(self, i=None):    
        if i == None:
            print 'first method'
        else:
            print 'second method',i

I have created a module specifically designed for command-line JSON manipulation:

https://github.com/ddopson/underscore-cli

• FLEXIBLE - THE "swiss-army-knife" tool for processing JSON data - can be used as a simple pretty-printer, or as a full-powered Javascript command-line
• POWERFUL - Exposes the full power and functionality of underscore.js (plus underscore.string)
• SIMPLE - Makes it simple to write JS one-liners similar to using "perl -pe"
• CHAINED - Multiple command invokations can be chained together to create a data processing pipeline
• MULTI-FORMAT - Rich support for input / output formats - pretty-printing, strict JSON, etc [coming soon]
• DOCUMENTED - Excellent command-line documentation with multiple examples for every command

It allows you to do powerful things really easily:

cat earthporn.json | underscore select '.data .title'
# [ 'Fjaðrárgljúfur canyon, Iceland [OC] [683x1024]',
#   'New town, Edinburgh, Scotland [4320 x 3240]',
#   'Sunrise in Bryce Canyon, UT [1120x700] [OC]',
# ...
#   'Kariega Game Reserve, South Africa [3584x2688]',
#   'Valle de la Luna, Chile [OS] [1024x683]',
#   'Frosted trees after a snowstorm in Laax, Switzerland [OC] [1072x712]' ]

cat earthporn.json | underscore select '.data .title' | underscore count
# 25

underscore map --data '[1, 2, 3, 4]' 'value+1'
# prints: [ 2, 3, 4, 5 ]

underscore map --data '{"a": [1, 4], "b": [2, 8]}' '_.max(value)'
# [ 4, 8 ]

echo '{"foo":1, "bar":2}' | underscore map -q 'console.log("key = ", key)'
# key = foo
# key = bar

underscore pluck --data "[{name : 'moe', age : 40}, {name : 'larry', age : 50}, {name : 'curly', age : 60}]" name
# [ 'moe', 'larry', 'curly' ]

underscore keys --data '{name : "larry", age : 50}'
# [ 'name', 'age' ]

underscore reduce --data '[1, 2, 3, 4]' 'total+value'
# 10

And it has one of the best "smart-whitespace" JSON formatters available:

If you have any feature requests, comment on this post or add an issue in github. I'd be glad to prioritize features that are needed by members of the community.

Use xpath more directly for both performance and clarity.

time_path <- "//start-valid-time"
temp_path <- "//temperature[@type='hourly']/value"

df <- data.frame(
    latitude=data[["number(//point/@latitude)"]],
    longitude=data[["number(//point/@longitude)"]],
    start_valid_time=sapply(data[time_path], xmlValue),
    hourly_temperature=as.integer(sapply(data[temp_path], as, "integer"))

leading to

> head(df, 2)
  latitude longitude          start_valid_time hourly_temperature
1    29.81    -82.42 2014-02-14T18:00:00-05:00                 60
2    29.81    -82.42 2014-02-14T19:00:00-05:00                 55

Because "append" existed long before "pop" was thought of. Python 0.9.1 supported list.append in early 1991. By comparison, here's part of a discussion on comp.lang.python about adding pop in 1997. Guido wrote:

To implement a stack, one would need to add a list.pop() primitive (and no, I'm not against this particular one on the basis of any principle). list.push() could be added for symmetry with list.pop() but I'm not a big fan of multiple names for the same operation -- sooner or later you're going to read code that uses the other one, so you need to learn both, which is more cognitive load.

You can also see he discusses the idea of if push/pop/put/pull should be at element [0] or after element [-1] where he posts a reference to Icon's list:

I stil think that all this is best left out of the list object implementation -- if you need a stack, or a queue, with particular semantics, write a little class that uses a lists

In other words, for stacks implemented directly as Python lists, which already supports fast append(), and del list[-1], it makes sense that list.pop() work by default on the last element. Even if other languages do it differently.

Implicit here is that most people need to append to a list, but many fewer have occasion to treat lists as stacks, which is why list.append came in so much earlier.

In C++17, we can use variants.

To use std::variant, you need to include the header:

#include <variant>

After that, you may add std::variant in your code like this:

using Type = std::variant<Animal, Person>;

template <class T>
void foo(Type type) {
    if (std::is_same_v<type, Animal>) {
        // Do stuff...
    } else {
        // Do stuff...
    }
}

@jim mcnamara: try using parentheses for around NF, i. e. $(NF-1) and $(NF) instead of $NF-1 and $NF (works on Mac OS X 10.6.8 for FreeBSD awkand gawk).

echo '
1 2
2 3
one
one two three
' | gawk '{if (NF >= 2) print $(NF-1), $(NF);}'

# output:
# 1 2
# 2 3
# two three

Like so many of you, I've been struggling with this for a while. The solution ultimately had to do with the div containing the UL. All suggestions on altering padding, width, etc. of the UL had no effect, but the following did.

It's all about the margin:0 auto; on the containing div. I hope this helps some people, and thanks to everyone else who already suggested this in combination with other things.

.divNav
{
    width: 99%;
    text-align:center;
    margin:0 auto; 
}

.divNav ul
{ 
    display:inline-block; 
    list-style:none;
    zoom: 1;
}

.divNav ul li 
{
    float:left;
    margin-right: .8em;       
    padding: 0; 
}

.divNav a,  #divNav a:visited
{
    width: 7.5em;
    display: block; 
    border: 1px solid #000;
    border-bottom:none;
    padding: 5px; 
    background-color:#F90;
    text-decoration: none;
    color:#FFF;
    text-align: center;
    font-family:Verdana, Geneva, sans-serif;
    font-size:1em;
}

When i copied the date format for timestamp and used that for date, it did not work. But changing the date format to this (DD-MON-YY HH12:MI:SS AM) worked for me.

The change has to be made in Tools->Preferences-> search for NLS

I wrote a program with wpf and used Database for showing images and this is my code:

SqlConnection con = new SqlConnection(@"Data Source=HITMAN-PC\MYSQL;
                                      Initial Catalog=Payam;
                                      Integrated Security=True");

SqlDataAdapter da = new SqlDataAdapter("select * from news", con);

DataTable dt = new DataTable();
da.Fill(dt);

string adress = dt.Rows[i]["ImgLink"].ToString();
ImageSource imgsr = new BitmapImage(new Uri(adress));
PnlImg.Source = imgsr;

I'd first split the file into few smaller ones like this

$ split --lines=50000 /path/to/large/file /path/to/output/file/prefix

and then grep on the resulting files.

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

You can try with Directory.GetFiles and fix your pattern

 string[] files = Directory.GetFiles(@"c:\", "*.txt");

 foreach (string file in files)
 {
    File.Copy(file, "....");
 }

 Or Move

 foreach (string file in files)
 {
    File.Move(file, "....");
 }

You can use perl to replace various characters, for example:

$ echo "Hello\ world" | perl -pe 's/\\/\\\\/g'
Hello\\ world

Depending on the nature of your escape, you can chain multiple calls to escape the proper characters.

  Language[] items = new Language[]{new Language("English", "En"),
                new Language("Italian", "It")};

            languagesCombo.ValueMember = "Alias";
            languagesCombo.DisplayMember = "FullName";
            languagesCombo.DataSource = items.ToList();

            languagesCombo.DropDownStyle = ComboBoxStyle.DropDownList;

 class Language
    {
        public string FullName { get; set; }
        public string Alias { get; set; }

        public Language(string fullName, string alias)
        {
            this.FullName = fullName;
            this.Alias = alias;
        }
    }

By making your drop down box "read-only" I am assuming you want to prevent user's typing in other options as opposed to being fully read-only where users cannot select a value??

If you wanted it to be fully read-only you could set the enabled property to be false.

I fought with this problem for a few hours before stumbling on the obvious answer. The problem I had was I was using different ssh implementations between when I generated my keys and when I used git.

I used ssh-keygen from the command prompt to generate my keys and but when I tried "git clone ssh://..." I got the same results as you, a prompt for the password and the message "fatal: The remote end hung up unexpectedly".

Determine which ssh windows is using by executing the Windows "where" command.

C:\where ssh
C:\Program Files (x86)\Git\bin\ssh.exe

The second line tells you which exact program will be executed.

Next you need to determine which ssh that git is using. Find this by:

C:\set GIT_SSH
GIT_SSH=C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe

And now you see the problem.

To correct this simply execute:

C:\set GIT_SSH=C:\Program Files (x86)\Git\bin\ssh.exe

To check if changes are applied:

C:\set GIT_SSH
GIT_SSH=C:\Program Files (x86)\Git\bin\ssh.exe

Now git will be able to use the keys that you generated earlier.

This fix is so far only for the current window. To fix it completely you need to change your environment variable.

1. Open Windows explorer
2. Right-click Computer and select Properties
3. Click Advanced System Settings link on the left
4. Click the Environment Variables... button
5. In the system variables section select the GIT_SSH variable and press the Edit... button
6. Update the variable value.
7. Press OK to close all windows

Now any future command windows you open will have the correct settings.

Hope this helps.

pretty sure you just want the plain old replace function. use like this:

myString.replace('username1','');

i suppose if you want to remove the trailing comma do this instead:

myString.replace('username1,','');

edit:

here is your site specific code:

jQuery("#post_like_list-510").text().replace(...) 

While performance issues are valid the real reasons in practice that you should avoid storing images in a database are for database management reasons. Your database will grow very rapidly and databases cost much more than simple file storage. Database backups and restores are much more expensive and time-consuming than file backup restores. In a pinch, you can restore a smaller database much more quickly than one bloated with images. Compare 1 TB of file storage on Azure to a 1 TB database and you'll see the vast difference in cost.

DateFormatSymbols class provides methods for our ease use.

To get short month strings. For example: "Jan", "Feb", etc.

getShortMonths()

To get month strings. For example: "January", "February", etc.

getMonths()

Sample code to return month string in mmm format,

private static String getShortMonthFromNumber(int month){
    if(month<0 || month>11){
        return "";
    }
    return new DateFormatSymbols().getShortMonths()[month];
}

This looks like a CSV file, so you could use the python csv module to read it. For example:

import csv

crimefile = open(fileName, 'r')
reader = csv.reader(crimefile)
allRows = [row for row in reader]

Using the csv module allows you to specify how things like quotes and newlines are handled. See the documentation I linked to above.

Take a look this how to use storages in android http://developer.android.com/guide/topics/data/data-storage.html#filesInternal

To read data from internal storage you need your app files folder and read content from here

String yourFilePath = context.getFilesDir() + "/" + "hello.txt";
File yourFile = new File( yourFilePath );

Also you can use this approach

FileInputStream fis = context.openFileInput("hello.txt");
InputStreamReader isr = new InputStreamReader(fis);
BufferedReader bufferedReader = new BufferedReader(isr);
StringBuilder sb = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
    sb.append(line);
}

Determine the data type of your data source column, "CreateDate". Make sure it is producing an actual datetime field and not something like a varchar. If your data source is a stored procedure, it is entirely possible that CreateDate is being processed to produce a varchar in order to format the date, like so:

SELECT CONVERT(varchar,TableName.CreateDate,126) AS CreateDate 
FROM TableName ...

Using CONVERT like this is often done to make query results fill the requirements of whatever other code is going to be processing those results. Style 126 is ISO 8601 format, an international standard that works with any language setting. I don't know what your industry is, but that was probably intentional. You don't want to mess with it. This style (126) produces a string representation of a date in the form '2013-04-29T18:15:20.270' just like you reported! However, if CreateDate's been processed this way then there's no way you'll be able to get your bf1.DataFormatString to show "29/04/2013" instead. You must first start with a datetime type column in your original SQL data source first for bf1 to properly consume it. So just add it to the data source query, and call it by a different name like CreateDate2 so as not to disturb whatever other code already depends on CreateDate, like this:

SELECT CONVERT(varchar,TableName.CreateDate,126) AS CreateDate, 
       TableName.CreateDate AS CreateDate2
FROM TableName ...

Then, in your code, you'll have to bind bf1 to "CreateDate2" instead of the original "CreateDate", like so:

BoundField bf1 = new BoundField();
bf1.DataField = "CreateDate2";
bf1.DataFormatString = "{0:dd/MM/yyyy}";
bf1.HtmlEncode = false;
bf1.HeaderText = "Sample Header 2";

dv.Fields.Add(bf1);

Voila! Your date should now show "29/04/2013" instead!

First copy the current string to a larger array with strcpy, then use strcat.

For example you can do:

char* str = "Hello";
char dest[12];

strcpy( dest, str );
strcat( dest, ".txt" );

I guess it will be a string. But the input parameters will be sent to the database & appropriate cast/conversions will be applied prior to creating an actual SQL statement.

To give you an example, it might try and see if the CAST/Conversion works.
If it works, it could create a final statement out of it.

   SELECT * From MyTable WHERE param = CAST('10; DROP TABLE Other' AS varchar(30))

Try an example with a SQL statement accepting a numeric parameter.
Now, try passing a string variable (with numeric content that is acceptable as numeric parameter). Does it raise any error?

Now, try passing a string variable (with content that is not acceptable as numeric parameter). See what happens?

To delete a single element, you could do:

std::vector<int> vec;

vec.push_back(6);
vec.push_back(-17);
vec.push_back(12);

// Deletes the second element (vec[1])
vec.erase(vec.begin() + 1);

Or, to delete more than one element at once:

// Deletes the second through third elements (vec[1], vec[2])
vec.erase(vec.begin() + 1, vec.begin() + 3);

Simply define a function and set the value of your Combobox to empty/null or whatever you want. Try the following.

def Reset():
    cmb.set("")

here, cmb is a variable in which you have assigned the Combobox. Now call that function in a button such as,

btn2 = ttk.Button(root, text="Reset",command=Reset)

FOR MVC

-- WEB.CONFIG CODE IN APP SETTING -- <add key="PhaseLevel" value="1" />

-- ON VIEWS suppose you want to show or hide something based on web.config Value--

-- WRITE THIS ON TOP OF YOUR PAGE-- @{ var phase = System.Configuration.ConfigurationManager.AppSettings["PhaseLevel"].ToString(); }

-- USE ABOVE VALUE WHERE YOU WANT TO SHOW OR HIDE.

@if (phase != "1") { @Html.Partial("~/Views/Shared/_LeftSideBarPartial.cshtml") }

It could be a good idea to be careful with the Locale upon which c.getTime().toString(); depends.

One idea is to store the time in seconds (e.g. UNIX time). As an int you can easily compare it, and then you just convert it to string when displaying it to the user.

You can use img.naturalWidth and img.naturalHeight to get real dimension of image in pixel

You can also use the sc tool to set it.

You can also call it from PowerShell and add additional checks if needed. The advantage of this tool vs. PowerShell is that the sc tool can also set the start type to auto delayed.

# Get Service status
$Service = "Wecsvc"
sc.exe qc $Service

# Set Service status
$Service = "Wecsvc"
sc.exe config $Service start= delayed-auto

Set the parent div as position:relative and the inner element to position:absolute; bottom:0

If you want to get the file names only without the rest of the commit message you can use:

git log --name-only --pretty=format: <branch name>

This can then be extended to use the various options that contain the file name:

git log --name-status --pretty=format: <branch name>

git log --stat --pretty=format: <branch name>

One thing to note when using this method is that there are some blank lines in the output that will have to be ignored. Using this can be useful if you'd like to see the files that have been changed on a local branch, but is not yet pushed to a remote branch and there is no guarantee the latest from the remote has already been pulled in. For example:

git log --name-only --pretty=format: my_local_branch --not origin/master

Would show all the files that have been changed on the local branch, but not yet merged to the master branch on the remote.

Try to avoid using a Mac/PC that has only 8 GB of RAM when doing Android development. As soon as you launch even 1 emulator (Genymotion or otherwise), your build times become extremely slow in Android Studio with gradle builds. This happens even if you make a simple one-line change to 1 source file.

Closing the emulator and using a real device helps a lot, but of course this is very limiting and less flexible. Reducing the RAM usage setting of the emulator can help, but the best way is to ensure your laptop has at least 12-16 GB of RAM.

Update (June 2017): There are now several good medium.com articles that explain how to speed up Android Studio gradle builds in detail, and it even works on 8 GB machines:

• How to decrease your Gradle build time by 65%: https://medium.com/@kevalpatel2106/how-to-decrease-your-gradle-build-time-by-65-310b572b0c43
• Make your Gradle builds fast again!: https://medium.com/@wasyl/make-your-gradle-builds-fast-again-ea323ce6a435

The summarised consensus is:

Create a gradle.properties file (either global at ~/.gradle/gradle.properties or local to project), and add the following lines:

org.gradle.daemon=true
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
org.gradle.parallel=true
org.gradle.configureondemand=true

ok I figured out a crude way of doing it.

I store the "n" value in the for loop when condition is satisfied in a list (lets call it delList) then do the following:

    for ii in sorted(delList, reverse=True):
    tupleX.pop(ii)

Any other suggestions are welcome too.

personaly, i'm using exceptions to handle validation. it requires following steps:

1. in your data binding expression, you need to add "ValidatesOnException=True"
2. in you data object you are binding to, you need to add DependencyPropertyChanged handler where you check if new value fulfills your conditions - if not - you restore to the object old value (if you need to) and you throw exception.
3. in your control template you use for displaying invalid value in the control, you can access Error collection and display exception message.

the trick here, is to bind only to objects which derive from DependencyObject. simple implementation of INotifyPropertyChanged wouldn't work - there is a bug in the framework, which prevents you from accessing error collection.

Instead of using pull-right class, it is better to use text-right class in the column, because pull-right creates problems sometimes while resizing the page.

This will be possible with setiosflags(ios::showpoint).

var Data= (from dealer in Dealer join dealercontact in DealerContact on dealer.ID equals dealercontact.DealerID
select new{
dealer.Id,
dealercontact.ContactName

}).ToList();

First, you aren't actually creating 10 buttons. Second, you need to set the location of each button, or they will appear on top of each other. This will do the trick:

  for (int i = 0; i < 10; ++i)
  {
      var button = new Button();
      button.Location = new Point(button.Width * i + 4, 0);
      Controls.Add(button);
  }

I had a similar problem. The catalina.out logged this log Message

Apr 17, 2013 5:14:46 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart

Check the localhost.log in the tomcat log directory (in the same directory as catalina.out), to see the exception which caused this error.

Be careful with the syntax! Great Turtle used them interchangeably, but:

error_page 404 = /404.html;

Will return the 404.html page with a status code of 200 (because = has relayed that to this page)

error_page 404 /404.html;

Will return the 404.html page with a (the original) 404 error code.

I know it's been quite a time since the beginning... There is a lot of wisdom in all these answers. Good indexing is the first thing when trying to improve a query. Well, almost the first. The most-first (so to speak) is making changes to code so that it's efficient. So, after all's been said and done, if one has a query with no WHERE, or when the WHERE-condition is not selective enough, there is only one way to get the data: TABLE SCAN (INDEX SCAN). If one needs all the columns from a table, then TABLE SCAN will be used - no question about it. This might be a heap scan or clustered index scan, depending on the type of data organization. The only last way to speed things up (if at all possible), is to make sure that as many cores are used as possible to do the scan: OPTION (MAXDOP 0). I'm ignoring the subject of storage, of course, but one should make sure that one has unlimited RAM, which goes without saying :)

For substring(startIndex, endIndex), startIndex is inclusive and endIndex are exclusive. The startIndex and endIndex are very confusing. I would understand substring(startIndex, length) to remember that.

You can just use the keywork value to accomplish this.

public int Hour {
    get{
        // Do some logic if you want
        //return some custom stuff based on logic

        // or just return the value
        return value;
    }; set { 
        // Do some logic stuff 
        if(value < MINVALUE){
            this.Hour = 0;
        } else {
            // Or just set the value
            this.Hour = value;
        }
    }
}

Because break cannot be used to break out of an if - it can only break out of loops. That's the way Python (and most other languages) are specified to behave.

What are you trying to do? Perhaps you should use sys.exit() or return instead?

A ClassCastException ocurrs when you try to cast an instance of an Object to a type that it is not. Casting only works when the casted object follows an "is a" relationship to the type you are trying to cast to. For Example

Apple myApple = new Apple();
Fruit myFruit = (Fruit)myApple;

This works because an apple 'is a' fruit. However if we reverse this.

Fruit myFruit = new Fruit();
Apple myApple = (Apple)myFruit;

This will throw a ClasCastException because a Fruit is not (always) an Apple.

It is good practice to guard any explicit casts with an instanceof check first:

if (myApple instanceof Fruit) {
  Fruit myFruit = (Fruit)myApple;
}

for md5 vARCHAR(32) is appropriate. For those using AES better to use varbinary.

<form id="uploadbanner" enctype="multipart/form-data" method="post" action="#">
   <input id="fileupload" name="myfile" type="file" />
   <input type="submit" value="submit" id="submit" />
</form>

To upload a file, it is essential to set enctype="multipart/form-data" on your form

You need that form type and then some php to process the file :)

You should probably check out Uploadify if you want something very customisable out of the box.

Simply use

this.Form.DefaultButton = MyButton.UniqueID;  

**Put your button id in place of 'MyButton'.

Just in case there is anyone else that stumbles on this page, if you want to string various permissions together in the one command, I used this:

icacls "c:\TestFolder" /grant:r Test_User:(OI)(CI)(RC,RD,RX)

Note the csv string for the various permissions.

As mainframer said, you can use grep, but i would use exit status for testing, try this:

#!/bin/bash
# Test if anotherstring is contained in teststring
teststring="put you string here"
anotherstring="string"

echo ${teststring} | grep --quiet "${anotherstring}"
# Exit status 0 means anotherstring was found
# Exit status 1 means anotherstring was not found

if [ $? = 1 ]
then
  echo "$anotherstring was not found"
fi

Yes: You can use Inner Join to join on multiple columns.

SELECT E.CaseNum, E.FileNum, E.ActivityNum, E.Grade, V.Score from Evaluation E
INNER JOIN Value V
ON E.CaseNum = V.CaseNum AND
    E.FileNum = V.FileNum AND 
    E.ActivityNum = V.ActivityNum

Create table

CREATE TABLE MyNewTab(CaseNum int, FileNum int,
    ActivityNum int, Grade int, Score varchar(100))

Insert values

INSERT INTO MyNewTab Values(CaseNum, FileNum, ActivityNum, Grade, Score)
SELECT E.CaseNum, E.FileNum, E.ActivityNum, E.Grade, V.Score from Evaluation E
INNER JOIN Value V
ON E.CaseNum = V.CaseNum AND
    E.FileNum = V.FileNum AND 
    E.ActivityNum = V.ActivityNum

It depends on the business and system.

If your userId is unique and will be unique all the time, you can use userId as your primary key. But if you ever want to expand your system, it will make things difficult. I advise you to add a foreign key in table user to make a relationship with table profile instead of adding a foreign key in table profile.

I've resolved this using:

.element:before {
    font-family: "Font Awesome 5 Free" , "CircularStd";
    content: "\f017" " Date";
}

Using the font family "font awesome 5 free" for the icon, and after, We have to specify the font that we are using again because if we doesn't do this, navigator will use the default font (times new roman or something like this).

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

You should be able to continue the sequences directly in your existing -f specification.

To skip both 5 and 7, try:

cut -d, -f-4,6-6,8-

As you're skipping a single sequential column, this can also be written as:

cut -d, -f-4,6,8-

To keep it going, if you wanted to skip 5, 7, and 11, you would use:

cut -d, -f-4,6-6,8-10,12-

To put it into a more-clear perspective, it is easier to visualize when you use starting/ending columns which go on the beginning/end of the sequence list, respectively. For instance, the following will print columns 2 through 20, skipping columns 5 and 11:

cut -d, -f2-4,6-10,12-20

So, this will print "2 through 4", skip 5, "6 through 10", skip 11, and then "12 through 20".

Seems like at least 10 questions rolled into one here, a couple points.

Response.Clear - it really depends on what else is going on in the app - if you have httpmodules early in the pipeline that might be writing stuff you don't want - then clear it. Test it and find out. Fiddler or Wireshark useful for this.

Content Type to text/xml - yup - good idea - read up on HTTP spec as to why this is important. IMO anyone doing web work should have read the 1.0 and 1.1 spec at least once.

Encoding - how is your xml encoded - if it is utf-8, then say so, if not, say something else appropriate, just make sure they all match.

Page - personally, would use ashx or httpmodule, if you are using page, and want it a bit faster, get rid of autoeventwireup and bind the event handlers manually.

Would probably be a bit of a waste of memory to dump the xml into a string first, but it depends a lot on the size of the xml as to whether you would ever notice.

As others have suggested, saving the xml to the output stream probably the fastest, I would normally do that, but if you aren't sure, test it, don't rely on what you read on the interweb. Don't just believe anything I say.

For another approach, if the xml doesn't change that much, you could just write it to the disk and serve the file directly, which would likely be quite performant, but like everything in programming, it depends...

Non VBA Solution:

Use Conditional Formatting rule with formula: =ISNA(A1) (to highlight cells with all errors - not only #N/A, use =ISERROR(A1))

VBA Solution:

Your code loops through 50 mln cells. To reduce number of cells, I use .SpecialCells(xlCellTypeFormulas, 16) and .SpecialCells(xlCellTypeConstants, 16)to return only cells with errors (note, I'm using If cell.Text = "#N/A" Then)

Sub ColorCells()
    Dim Data As Range, Data2 As Range, cell As Range
    Dim currentsheet As Worksheet

    Set currentsheet = ActiveWorkbook.Sheets("Comparison")

    With currentsheet.Range("A2:AW" & Rows.Count)
        .Interior.Color = xlNone
        On Error Resume Next
        'select only cells with errors
        Set Data = .SpecialCells(xlCellTypeFormulas, 16)
        Set Data2 = .SpecialCells(xlCellTypeConstants, 16)
        On Error GoTo 0
    End With

    If Not Data2 Is Nothing Then
        If Not Data Is Nothing Then
            Set Data = Union(Data, Data2)
        Else
            Set Data = Data2
        End If
    End If

    If Not Data Is Nothing Then
        For Each cell In Data
            If cell.Text = "#N/A" Then
               cell.Interior.ColorIndex = 4
            End If
        Next
    End If
End Sub

Note, to highlight cells witn any error (not only "#N/A"), replace following code

If Not Data Is Nothing Then
   For Each cell In Data
       If cell.Text = "#N/A" Then
          cell.Interior.ColorIndex = 3
       End If
   Next
End If

with

If Not Data Is Nothing Then Data.Interior.ColorIndex = 3

UPD: (how to add CF rule through VBA)

Sub test()
    With ActiveWorkbook.Sheets("Comparison").Range("A2:AW" & Rows.Count).FormatConditions
        .Delete
        .Add Type:=xlExpression, Formula1:="=ISNA(A1)"
        .Item(1).Interior.ColorIndex = 3
    End With
End Sub

If all you need is the classpath entries, I do something like the following to use the eclipse build path.

<xmlproperty file=".classpath" collapseAttributes="true" delimiter=";" />

Then set that value in the path

<path id="eclipse.classpath">
    <pathelement path="${classpath.classpathentry.path}"/>
</path>


<target name="compile" depends="init">

    <javac srcdir="${src}" destdir="${build}" updatedProperty="compiled">
        <classpath refid="eclipse.classpath"/>
    </javac>
</target>

Since GDB 7.5 you can use these native Convenience Functions:

$_memeq(buf1, buf2, length)
$_regex(str, regex)
$_streq(str1, str2)
$_strlen(str)

Seems quite less problematic than having to execute a "foreign" strcmp() on the process' stack each time the breakpoint is hit. This is especially true for debugging multithreaded processes.

Note your GDB needs to be compiled with Python support, which is not an issue with current linux distros. To be sure, you can check it by running show configuration inside GDB and searching for --with-python. This little oneliner does the trick, too:

$ gdb -n -quiet -batch -ex 'show configuration' | grep 'with-python'
             --with-python=/usr (relocatable)

For your demo case, the usage would be

break <where> if $_streq(x, "hello")

or, if your breakpoint already exists and you just want to add the condition to it

condition <breakpoint number> $_streq(x, "hello")

$_streq only matches the whole string, so if you want something more cunning you should use $_regex, which supports the Python regular expression syntax.

Go to you MainActivity.java and below this code
-> NavigationView navigationView = findViewById(R.id.nav_view);
Add single line of code -> navigationView.setItemIconTintList(null);
i.e. the last line of my code

I hope this might solve your problem.

public class MainActivity extends AppCompatActivity {

    private AppBarConfiguration mAppBarConfiguration;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);
        navigationView.setItemIconTintList(null);

In my case also \n was not working, I fixed issue by keeping number of lines to 0 and copied and pasted the text with new line itself for example instead of Hello \n World i pasted

Hello

World

in the interface builder.

You need to open the file in binary mode i.e. wb instead of w. If you don't, the end of line characters are auto-converted to OS specific ones.

Here is an excerpt from Python reference about open().

The default is to use text mode, which may convert '\n' characters to a platform-specific representation on writing and back on reading.

You do not need the line:

import { SigninComponent, RegisterComponent } from './auth/auth.module';

in your app.component.ts as you already included the AuthModule in your app.module.ts. AutModule import is sufficient to use your component in the app.

The error that you get is a TypeScript error, not a Angular one, and it is correct in stating that there is no exported member, as it searches for a valid EC6 syntax for export, not angular module export. This line would thus work in your app.component.ts:

import { SigninComponent } from './auth/components/signin.component';

value_counts omits NaN by default so you're most likely dealing with "".

So you can just filter them out like

filter = df["Tenant"] != ""
dfNew = df[filter]

Version A is simpler and that's why I would use it.

And if you turn on all compiler warnings in Java you will get a warning on the second Version because it is unnecesarry and turns up code complexity.

Another option is

Private Sub Worksheet_Change(ByVal Target As Range)
    IF Target.Address = "$D$2" Then
        MsgBox("Cell D2 Has Changed.")
    End If
End Sub

I believe this uses fewer resources than Intersect, which will be helpful if your worksheet changes a lot.

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

You can also set the title of your chart by adding the title parameter as follows

ax.set(xlabel='common xlabel', ylabel='common ylabel', title='some title')

If you have access to the script console (Manage Jenkins -> Script Console), then you can do this following:

Jenkins.instance.getItemByFullName("YourJobName").updateNextBuildNumber(45)

Can't you just make a copy constructor? By the way Java always passes references by value, so you keep pointing to the same object.

The following example for complex numbers should be self explanatory including the error message at the end

>>> x=complex(1,2)
>>> print x
(1+2j)
>>> y=complex(3,4)
>>> print y
(3+4j)
>>> z=x+y
>>> print x
(1+2j)
>>> print z
(4+6j)
>>> z=x*y
>>> print z
(-5+10j)
>>> z=x/y
>>> print z
(0.44+0.08j)
>>> print x.conjugate()
(1-2j)
>>> print x.imag
2.0
>>> print x.real
1.0
>>> print x>y

Traceback (most recent call last):
  File "<pyshell#149>", line 1, in <module>
    print x>y
TypeError: no ordering relation is defined for complex numbers

An example using CSS

  ul li:not(:last-child){
        border-right: 1px solid rgba(153, 151, 151, 0.75);
    }

For this you can use .9 Patch Image and just simply set it in to background.

android:background="@drawable/spin"

Here i'll give you .9patch image. try with this.

Right click on image and click Save Image as

set image name like this : anyname.9.png and hit save.

This is answered in the Protractor FAQ: https://github.com/angular/protractor/blob/master/docs/faq.md#the-result-of-gettext-from-an-input-element-is-always-empty

The result of getText from an input element is always empty

This is a webdriver quirk. and elements always have empty getText values. Instead, try:

element.getAttribute('value')

As for question 2, yes, you should be able to use a fully qualified name for by.binding. I suspect that your template does not actually having an element that is bound to risk.name via {{}} or ng-bind.

It's possible to utilize custom command line options in Gradle to end up with something like:

./gradlew printPet --pet="puppies!"

However, custom command line options in Gradle are an incubating feature.

Java solution

To end up with something like this follow the instructions here:

import org.gradle.api.tasks.options.Option;

public class PrintPet extends DefaultTask {
    private String pet;

    @Option(option = "pet", description = "Name of the cute pet you would like to print out!")
    public void setPet(String pet) {
        this.pet = pet;
    }

    @Input
    public String getPet() {
        return pet;
    }

    @TaskAction
    public void print() {
        getLogger().quiet("'{}' are awesome!", pet);
    }
}

Then register it:

task printPet(type: PrintPet)

Now you can do:

./gradlew printPet --pet="puppies"

output:

Puppies! are awesome!

Kotlin solution

open class PrintPet : DefaultTask() {

    @Suppress("UnstableApiUsage")
    @set:Option(option = "pet", description = "The cute pet you would like to print out")
    @get:Input
    var pet: String = ""

    @TaskAction
    fun print() {    
        println("$pet are awesome!")
    }
}

then register the task with:

tasks.register<PrintPet>("printPet")

There is an illustrative example of how to create custom colormaps here. The docstring is essential for understanding the meaning of cdict. Once you get that under your belt, you might use a cdict like this:

cdict = {'red':   ((0.0, 1.0, 1.0), 
                   (0.1, 1.0, 1.0),  # red 
                   (0.4, 1.0, 1.0),  # violet
                   (1.0, 0.0, 0.0)), # blue

         'green': ((0.0, 0.0, 0.0),
                   (1.0, 0.0, 0.0)),

         'blue':  ((0.0, 0.0, 0.0),
                   (0.1, 0.0, 0.0),  # red
                   (0.4, 1.0, 1.0),  # violet
                   (1.0, 1.0, 0.0))  # blue
          }

Although the cdict format gives you a lot of flexibility, I find for simple gradients its format is rather unintuitive. Here is a utility function to help generate simple LinearSegmentedColormaps:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors as mcolors


def make_colormap(seq):
    """Return a LinearSegmentedColormap
    seq: a sequence of floats and RGB-tuples. The floats should be increasing
    and in the interval (0,1).
    """
    seq = [(None,) * 3, 0.0] + list(seq) + [1.0, (None,) * 3]
    cdict = {'red': [], 'green': [], 'blue': []}
    for i, item in enumerate(seq):
        if isinstance(item, float):
            r1, g1, b1 = seq[i - 1]
            r2, g2, b2 = seq[i + 1]
            cdict['red'].append([item, r1, r2])
            cdict['green'].append([item, g1, g2])
            cdict['blue'].append([item, b1, b2])
    return mcolors.LinearSegmentedColormap('CustomMap', cdict)


c = mcolors.ColorConverter().to_rgb
rvb = make_colormap(
    [c('red'), c('violet'), 0.33, c('violet'), c('blue'), 0.66, c('blue')])
N = 1000
array_dg = np.random.uniform(0, 10, size=(N, 2))
colors = np.random.uniform(-2, 2, size=(N,))
plt.scatter(array_dg[:, 0], array_dg[:, 1], c=colors, cmap=rvb)
plt.colorbar()
plt.show()

By the way, the for-loop

for i in range(0, len(array_dg)):
  plt.plot(array_dg[i], markers.next(),alpha=alpha[i], c=colors.next())

plots one point for every call to plt.plot. This will work for a small number of points, but will become extremely slow for many points. plt.plot can only draw in one color, but plt.scatter can assign a different color to each dot. Thus, plt.scatter is the way to go.

with cursor for loop (user = 'TRANEE', table = 'D')

declare
    constr all_constraints.constraint_name%TYPE;
begin
    for constr in
        (select constraint_name from all_constraints
        where table_name = 'D'
        and owner = 'TRANEE')
    loop
        execute immediate 'alter table D disable constraint '||constr.constraint_name;
    end loop;
end;
/

(If you change disable to enable, you can make all constraints enable)

First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

Or you can do something like:

Old versions Laravel.

Model::all()->take(10)->get();

Newer version Laravel.

Model::all()->take(10);

First I tried everything that I have read on stackoverflow...from updating gradle to XY version, to updating ConstraintLayout to XY version...I even update my SDK tools and Android Studio to the latest version...but nothing was working.

The only solution that worked for me was that I delete ConstraintLayout library from gradle and SDK, then I opened random xml layout and in Design view under Palette section search for ConstraintLayout. If you have successfully deleted library from your project then you will be able to install the library from there if you double clicked on ConstraintLayout element.

That has create next line in my app build.gradle:

'com.android.support.constraint:constraint-layout:1.0.0-beta1'

In my project build.gradle I have this:

classpath 'com.android.tools.build:gradle:2.2.2'

Android studio version 2.2.2

attr_accessor is just a method. (The link should provide more insight with how it works - look at the pairs of methods generated, and a tutorial should show you how to use it.)

The trick is that class is not a definition in Ruby (it is "just a definition" in languages like C++ and Java), but it is an expression that evaluates. It is during this evaluation when the attr_accessor method is invoked which in turn modifies the current class - remember the implicit receiver: self.attr_accessor, where self is the "open" class object at this point.

The need for attr_accessor and friends, is, well:

1. Ruby, like Smalltalk, does not allow instance variables to be accessed outside of methods¹ for that object. That is, instance variables cannot be accessed in the x.y form as is common in say, Java or even Python. In Ruby y is always taken as a message to send (or "method to call"). Thus the attr_* methods create wrappers which proxy the instance @variable access through dynamically created methods.

2. Boilerplate sucks

Hope this clarifies some of the little details. Happy coding.

¹ This isn't strictly true and there are some "techniques" around this, but there is no syntax support for "public instance variable" access.

The following snippets test for the "not contains" condition, as exemplified in the sample pseudocode in the question. For a direct solution with explicit looping, do this:

boolean contains = false;
for (char c : charArray) {
    if (c == 'q') {
        contains = true;
        break;
    }
}
if (!contains) {
    // do something
}

Another alternative, using the fact that String provides a contains() method:

if (!(new String(charArray).contains("q"))) {
    // do something
}

Yet another option, this time using indexOf():

if (new String(charArray).indexOf('q') == -1) {
    // do something
}

Add a reference to Microsoft.VisualBasic and a using Microsoft.VisualBasic.Devices;.

The ComputerInfo class has all the information that you need.

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

This is for cases that you want to use interpolated strings. I'm actually posting this because I'm tired of trial and error and eventually scrolling through tons of docs every time I need to format some scalar.

Performance Warning

Interpolated strings are slow. In my experience this is the order (fast to slow):

1. value.ToString(format)+" blah blah"
2. string.Format("{0:format} blah blah", value)
3. $"{value:format} blah blah"

For windows quotes are required and ; should be used as separator. e.g.:

java -cp "target\\*;target\\dependency\\*" my.package.Main

For Python Run This Command

apt-get install -y python-setuptools

For Python 3.

apt-get install -y python3-setuptools

You can use also "void*" (void pointer) to send an address to the function.

typedef struct pstring_t {
    char * chars;
    int(*length)(void*);
} PString;

int length(void* self) {
    return strlen(((PString*)self)->chars);
}

PString initializeString() {
    PString str;
    str.length = &length;
    return str;
}

int main()
{
    PString p = initializeString();

    p.chars = "Hello";

    printf("Length: %i\n", p.length(&p));

    return 0;
}

Output:

Length: 5

NSString's method is lowercaseString (0 arguments), not lowercaseString: (1 argument).

One item that seems to have been missed is star transformations. Index Intersection operators resolve the predicate by calculating the set of rows hit by each of the predicates before any I/O is done on the fact table. On a star schema you would index each individual dimension key and the query optimiser can resolve which rows to select by the index intersection computation. The indexes on individual columns give the best flexibility for this.

Use a <br> tag to create a line break in the document

document.write("<br>");

Here's a sample fiddle

• http://jsfiddle.net/g6eAF/

You want to use the .getline function in cin.

#include <iostream>
using namespace std;

int main () {
  char name[256], title[256];

  cout << "Enter your name: ";
  cin.getline (name,256);

  cout << "Enter your favourite movie: ";
  cin.getline (title,256);

  cout << name << "'s favourite movie is " << title;

  return 0;
}

Took the example from here. Check it out for more info and examples.

Using Thread.interrupt() is a perfectly acceptable way of doing this. In fact, it's probably preferrable to a flag as suggested above. The reason being that if you're in an interruptable blocking call (like Thread.sleep or using java.nio Channel operations), you'll actually be able to break out of those right away.

If you use a flag, you have to wait for the blocking operation to finish and then you can check your flag. In some cases you have to do this anyway, such as using standard InputStream/OutputStream which are not interruptable.

In that case, when a thread is interrupted, it will not interrupt the IO, however, you can easily do this routinely in your code (and you should do this at strategic points where you can safely stop and cleanup)

if (Thread.currentThread().isInterrupted()) {
  // cleanup and stop execution
  // for example a break in a loop
}

Like I said, the main advantage to Thread.interrupt() is that you can immediately break out of interruptable calls, which you can't do with the flag approach.

None of the solutions worked for me. What solved my problem was under the drop down arrow in the Variable window. On the Layout option, I had to choose "Variables View Only" and then I could see the variable's values again.

This problem also suddenly appear out of nowhere. One moment Debug was working and the next it wasn't.

Maybe create a temporary memory table with columns (key, value) if you want associative arrays. Having a memory table is the closest thing to having arrays in mysql

A MonkeyPatch is a piece of Python code which extends or modifies other code at runtime (typically at startup).

A simple example looks like this:

from SomeOtherProduct.SomeModule import SomeClass

def speak(self):
    return "ook ook eee eee eee!"

SomeClass.speak = speak

I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {} statements.

Each time the switch function is the same but the command we supply changes.

do.this <- "T1"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
#########################################################
do.this <- "T2"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
########################################################
do.this <- "T3"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)

Here it is inside a function:

FUN <- function(df, do.this){
    switch(do.this,
        T1={X <- t(df)
            P <- colSums(df)%*%X
        },
        T2={X <- colMeans(df)
            P <- outer(X, X)
        },
        stop("Enter something that switches me!")
    )
    return(P)
}

FUN(mtcars, "T1")
FUN(mtcars, "T2")
FUN(mtcars, "T3")

"The list are variables/paramaters that is pre-defined as comma separated lists". Do you mean that your query is actually

UPDATE tab1   SET budgpost_gr1=     
CASE  WHEN (budgpost in ('1001,1012,50055'))  THEN 'BP_GR_A'   
      WHEN (budgpost in ('5,10,98,0'))  THEN 'BP_GR_B'  
      WHEN (budgpost in ('11,876,7976,67465'))     
      ELSE 'Missing' END`

If so, you need a function to take a string and parse it into a list of numbers.

create type tab_num is table of number;

create or replace function f_str_to_nums (i_str in varchar2) return tab_num is
  v_tab_num tab_num := tab_num();
  v_start   number := 1;
  v_end     number;
  v_delim   VARCHAR2(1) := ',';
  v_cnt     number(1) := 1;
begin
  v_end := instr(i_str||v_delim,v_delim,1, v_start);
  WHILE v_end > 0 LOOP
    v_cnt := v_cnt + 1;
    v_tab_num.extend;
    v_tab_num(v_tab_num.count) := 
                  substr(i_str,v_start,v_end-v_start);
    v_start := v_end + 1;
    v_end := instr(i_str||v_delim,v_delim,v_start);
  END LOOP;
  RETURN v_tab_num;
end;
/

Then you can use the function like so:

select column_id, 
   case when column_id in 
     (select column_value from table(f_str_to_nums('1,2,3,4'))) then 'red' 
   else 'blue' end
from  user_tab_columns
where table_name = 'EMP'

If you want to measure CPU time, can use time.process_time() for Python 3.3 and above:

import time
start = time.process_time()
# your code here    
print(time.process_time() - start)

First call turns the timer on, and second call tells you how many seconds have elapsed.

There is also a function time.clock(), but it is deprecated since Python 3.3 and will be removed in Python 3.8.

There are better profiling tools like timeit and profile, however time.process_time() will measure the CPU time and this is what you're are asking about.

If you want to measure wall clock time instead, use time.time().

I ran into this situation and creating an extra div was impractical. I ended up just setting the full-height div to height: 10000%; overflow: hidden;

Clearly not the cleanest solution, but it works really fast.

You can use contains:

string[] example = { "sample1", "sample2" };
var result = (from c in example where c.Contains("2") select c);
// returns only sample2

Works for me. How log all php errors to a log fiie?

Just add following line to /etc/php.ini to log errors to specified file – /var/log/php-scripts.log

vi /etc/php.ini

Modify error_log directive

error_log = /var/log/php-scripts.log

Make sure display_errors set to Off (no errors to end users)

display_errors = Off

Save and close the file. Restart web server:

/etc/init.d/httpd restart

How do I log errors to syslog or Windows Server Event Log?

Modify error_log as follows :

error_log = syslog

How see logs?

Login using ssh or download a log file /var/log/php-scripts.log using sftp:
$ sudo tail -f /var/log/php-scripts.log

Python 3.6+ provides built-in convenience methods to find and decode the plain text body as in @Todor Minakov's answer. You can use the EMailMessage.get_body() and get_content() methods:

msg = email.message_from_string(s, policy=email.policy.default)
body = msg.get_body(('plain',))
if body:
    body = body.get_content()
print(body)

Note this will give None if there is no (obvious) plain text body part.

If you are reading from e.g. an mbox file, you can give the mailbox constructor an EmailMessage factory:

mbox = mailbox.mbox(mboxfile, factory=lambda f: email.message_from_binary_file(f, policy=email.policy.default), create=False)
for msg in mbox:
    ...

Note you must pass email.policy.default as the policy, since it's not the default...

To set a session-timeout that never expires is not desirable because you would be reliable on the user to push the logout-button every time he's finished to prevent your server of too much load (depending on the amount of users and the hardware). Additionaly there are some security issues you might run into you would rather avoid.

The reason why the session gets invalidated while the server is still working on a task is because there is no communication between client-side (users browser) and server-side through e.g. a http-request. Therefore the server can't know about the users state, thinks he's idling and invalidates the session after the time set in your web.xml.

To get around this you have several possibilities:

• You could ping your backend while the task is running to touch the session and prevent it from being expired
• increase the <session-timeout> inside the server but I wouldn't recommend this
• run your task in a dedicated thread which touches (extends) the session while working or notifies the user when the thread has finished

There was a similar question asked, maybe you can adapt parts of this solution in your project. Have a look at this.

Hope this helps, have Fun!

getRowRects

Element.getClientRects() works like this

each rects in the same row has the same top value, so find out the rects with different top value, like this

function getRowRects(element) {
    var rects = [],
        clientRects = element.getClientRects(),
        len = clientRects.length,
        clientRect, top, rectsLen, rect, i;

    for(i=0; i<len; i++) {
        has = false;
        rectsLen = rects.length;
        clientRect = clientRects[i];
        top = clientRect.top;
        while(rectsLen--) {

After long time looking into TextView class I found a way to prevent keyboard to appears. The trick is hide it right after it appears, so I searched a method that is called after keyboard appear and hide it.

Implemented EditText class

public class NoImeEditText extends EditText {

    public NoImeEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    /**
     * This method is called before keyboard appears when text is selected.
     * So just hide the keyboard
     * @return
     */
    @Override
    public boolean onCheckIsTextEditor() {
        hideKeyboard();

        return super.onCheckIsTextEditor();
    }

    /**
     * This methdod is called when text selection is changed, so hide keyboard to prevent it to appear
     * @param selStart
     * @param selEnd
     */
    @Override
    protected void onSelectionChanged(int selStart, int selEnd) {
        super.onSelectionChanged(selStart, selEnd);

        hideKeyboard();
    }

    private void hideKeyboard(){
        InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(getWindowToken(), 0);
    }
}

and style

<com.my.app.CustomViews.NoImeEditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:editable="false"
    android:background="@null"
    android:textSize="@dimen/cell_text" />

If you want to use standard extra data field, you would do something like this:

private Uri imageUri;
....
Intent intent = new Intent(this, GoogleActivity.class);
intent.putExtra(Intent.EXTRA_STREAM, imageUri.toString());
startActivity(intent);
this.finish();

The documentation for Intent says:

EXTRA_STREAM   added in API level 1 
String EXTRA_STREAM
A content: URI holding a stream of data associated with the Intent,
used with ACTION_SEND to supply the data being sent. 

Constant Value: "android.intent.extra.STREAM"

You don't have to use the built-in standard names, but it's probably good practice and more reusable. Take a look at the developer documentation for a list of all the built-in standard extra data fields.

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

my 2cents would be to use json.MarshalIndent -- surprised this isn't suggested, as it is the most straightforward. for example:

func prettyPrint(i interface{}) string {
    s, _ := json.MarshalIndent(i, "", "\t")
    return string(s)
}

no external deps and results in nicely formatted output.

if you want just the parts of url after http://domain.com, try this:

<?php echo $_SERVER['REQUEST_URI']; ?>

if the current url was http://domain.com/some-slug/some-id, echo will return only '/some-slug/some-id'.

if you want the full url, try this:

<?php echo 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; ?>

In May 2017 Google announced the Google Maps URLs API that allows to construct universal cross-platform links. Now you can open Google maps on web, Android or iOS using the same URL string in form:

https://www.google.com/maps/search/?api=1&parameters

There are several modes that you can use: search, directions, show map and show street view.

So you can use something like

https://www.google.com/maps/search/?api=1&query=58.698017,-152.522067

to open map and place marker on some lat and lng.

Javascript has push and pop methods, which operate on ordinary Javascript array objects.

For queues, look here:

http://safalra.com/web-design/javascript/queues/

Queues can be implemented in JavaScript using either the push and shift methods or unshift and pop methods of the array object. Although this is a simple way to implement queues, it is very inefficient for large queues — because of the methods operate on arrays, the shift and unshift methods move every element in the array each time they are called.

Queue.js is a simple and efficient queue implementation for JavaScript whose dequeue function runs in amortized constant time. As a result, for larger queues, it can be significantly faster than using arrays.

$value = preg_replace('~\.0+$~','',$value);

Python 3 includes an improved super() which allows use like this:

super().__init__(args)

An alternative solution is to introduce a method to the file instance that would do the explicit conversion.

import types

def _write_str(self, ascii_str):
    self.write(ascii_str.encode('ascii'))

source_file = open("myfile.bin", "wb")
source_file.write_str = types.MethodType(_write_str, source_file)

And then you can use it as source_file.write_str("Hello World").

You might find the git_remote_branch tool useful. It offers simple commands for creating, publishing, deleting, tracking & renaming remote branches. One nice feature is that you can ask a grb command to explain what git commands it would execute.

grb explain create my_branch github
# git_remote_branch version 0.3.0

# List of operations to do to create a new remote branch and track it locally:
git push github master:refs/heads/my_branch
git fetch github
git branch --track my_branch github/my_branch
git checkout my_branch

Could write a udf and take a value to tell it which day of the week should be 1 would look like this (drawing on answer from John to use MOD instead of CASE):

DROP FUNCTION IF EXISTS `reporting`.`udfDayOfWeek`;
DELIMITER |
CREATE FUNCTION `reporting`.`udfDayOfWeek` (
  _date DATETIME,
  _firstDay TINYINT
) RETURNS tinyint(4)
FUNCTION_BLOCK: BEGIN
  DECLARE _dayOfWeek, _offset TINYINT;
  SET _offset = 8 - _firstDay;
  SET _dayOfWeek = (DAYOFWEEK(_date) + _offset) MOD 7;
  IF _dayOfWeek = 0 THEN
    SET _dayOfWeek = 7;
  END IF;
  RETURN _dayOfWeek;
END FUNCTION_BLOCK

To call this function to give you the current day of week value when your week starts on a Tuesday for instance, you'd call:

SELECT udfDayOfWeek(NOW(), 3);

Nice thing about having it as a udf is you could also call it on a result set field like this:

SELECT
  udfDayOfWeek(p.SignupDate, 3) AS SignupDayOfWeek,
  p.FirstName,
  p.LastName
FROM Profile p;

Here's what I get.

I'm using Visual Studio Code and its Terminal to execute the 'npm' commands.

Visual Studio Code (not as administrator)
PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator)
Run this command after I've run something like 'ng serve'

PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator - closing and opening the IDE)
If I have already executed other commands that would impact node modules I decided to try closing Visual Studio Code first, opening it up as Administrator then running the command:

PS g:\labs\myproject> npm install bootstrap@3

Result I get then is: + [email protected]
added 115 packages and updated 1 package in 24.685s

This is not a permanent solution since I don't want to continue closing down VS Code every time I want to execute an npm command, but it did resolve the issue to a point.

This appears to be a very simple answer on how to differentiate between fact and dimension tables!

It may help to think of dimensions as things or objects. A thing such as a product can exist without ever being involved in a business event. A dimension is your noun. It is something that can exist independent of a business event, such as a sale. Products, employees, equipment, are all things that exist. A dimension either does something, or has something done to it.

Employees sell, customers buy. Employees and customers are examples of dimensions, they do.

Products are sold, they are also dimensions as they have something done to them.

Facts, are the verb. An entry in a fact table marks a discrete event that happens to something from the dimension table. A product sale would be recorded in a fact table. The event of the sale would be noted by what product was sold, which employee sold it, and which customer bought it. Product, Employee, and Customer are all dimensions that describe the event, the sale.

In addition fact tables also typically have some kind of quantitative data. The quantity sold, the price per item, total price, and so on.

You could use .gitignore to keep the config.xml out of the repository, and then use a post commit hook to upload the appropriate config.xml file to the server.

Finding primes up to a 100 is especially nice and easy:

    printf("2 3 ");                        // first two primes are 2 and 3
    int m5 = 25, m7 = 49, i = 5, d = 4;
    for( ; i < 25; i += (d=6-d) )
    {
        printf("%d ", i);                  // all 6-coprimes below 5*5 are prime
    }
    for( ; i < 49; i += (d=6-d) )
    {
        if( i != m5) printf("%d ", i);
        if( m5 <= i ) m5 += 10;            // no multiples of 5 below 7*7 allowed!
    }
    for( ; i < 100; i += (d=6-d) )         // from 49 to 100,
    {
        if( i != m5 && i != m7) printf("%d ", i);
        if( m5 <= i ) m5 += 10;            //   sieve by multiples of 5,
        if( m7 <= i ) m7 += 14;            //                       and 7, too
    }

The square root of 100 is 10, and so this rendition of the sieve of Eratosthenes with the 2-3 wheel uses the multiples of just the primes above 3 that are not greater than 10 -- viz. 5 and 7 alone! -- to sieve the 6-coprimes below 100 in an incremental fashion.

I feel your pain, I'm trying to do the same thing. In my case I just want to clear the user.

I've created a base controller class that all my controllers inherit from. In it I override OnAuthentication and set the filterContext.HttpContext.User to null

That's the best I've managed to far...

public abstract class ApplicationController : Controller   
{
    ...
    protected override void OnAuthentication(AuthenticationContext filterContext)
    {
        base.OnAuthentication(filterContext); 

        if ( ... )
        {
            // You may find that modifying the 
            // filterContext.HttpContext.User 
            // here works as desired. 
            // In my case I just set it to null
            filterContext.HttpContext.User = null;
        }
    }
    ...
}

a += b is shorthand for a = a +b which means:

1) 1 += 2 // won't compile

2) 15

@CarlosLanderas is correct depending on where you've placed the DIV control. The DIV by the way is not technically an ASP control, which is why you cannot find it directly like other controls. But the best way around this is to turn it into an ASP control.

Use asp:Panel instead. It is rendered into a <div> tag anyway...

<asp:Panel id="divSubmitted" runat="server" style="text-align:center" visible="false">
   <asp:Label ID="labSubmitted" runat="server" Text="Roll Call Submitted"></asp:Label>
</asp:Panel>

And in code behind, simply find the Panel control as per normal...

Panel DivCtl1 = (Panel)gvRollCall.FooterRow.FindControl("divSubmitted");
if (DivCtl1 != null)
    DivCtl1.Visible = true;

Please note that I've used FooterRow, as my "psuedo div" is inside the footer row of a Gridview control.

Good coding!

OK, this question has been answered and answer accepted but someone asked me to put my answer so there you go.

First of all, it is not possible to say for sure. It is an internal implementation detail and not documented. However, based on the objects included in the other object. Now, how do we calculate the memory requirement for our cached objects?

I had previously touched this subject in this article:

Now, how do we calculate the memory requirement for our cached objects? Well, as most of you would know, Int32 and float are four bytes, double and DateTime 8 bytes, char is actually two bytes (not one byte), and so on. String is a bit more complex, 2*(n+1), where n is the length of the string. For objects, it will depend on their members: just sum up the memory requirement of all its members, remembering all object references are simply 4 byte pointers on a 32 bit box. Now, this is actually not quite true, we have not taken care of the overhead of each object in the heap. I am not sure if you need to be concerned about this, but I suppose, if you will be using lots of small objects, you would have to take the overhead into consideration. Each heap object costs as much as its primitive types, plus four bytes for object references (on a 32 bit machine, although BizTalk runs 32 bit on 64 bit machines as well), plus 4 bytes for the type object pointer, and I think 4 bytes for the sync block index. Why is this additional overhead important? Well, let’s imagine we have a class with two Int32 members; in this case, the memory requirement is 16 bytes and not 8.

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

It is not a good thing to have to specify DIP or SP again by code when already defined in a dimen.xml file.

I think that the best option is to use PX when using a dimen.xml value :

tv.setTextSize(TypedValue.COMPLEX_UNIT_PX, getResources().getDimensionPixelSize(R.dimen.txt_size));

This way, you can switch from DP to SP if needed in dimen.xml file without having to change any code.

Here is my way of solving this problem (Swift 4):

The idea was to make the simplest possible solution which allows to use placeholders of different colors, resizes to placeholders size, will not overwrite a delegate meanwhile keeping all UITextView functions work as expected.

import UIKit

class PlaceholderTextView: UITextView {
    var placeholderColor: UIColor = .lightGray
    var defaultTextColor: UIColor = .black

    private var isShowingPlaceholder = false {
        didSet {
            if isShowingPlaceholder {
                text = placeholder
                textColor = placeholderColor
            } else {
                textColor = defaultTextColor
            }
        }
    }

    var placeholder: String? {
        didSet {
            isShowingPlaceholder = !hasText
        }
    }

    @objc private func textViewDidBeginEditing(notification: Notification) {
        textColor = defaultTextColor
        if isShowingPlaceholder { text = nil }
    }

    @objc private func textViewDidEndEditing(notification: Notification) {
        isShowingPlaceholder = !hasText
    }

    // MARK: - Construction -
    override init(frame: CGRect, textContainer: NSTextContainer?) {
        super.init(frame: frame, textContainer: textContainer)
        setup()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setup()
    }

    private func setup() {
        NotificationCenter.default.addObserver(self, selector: #selector(textViewDidBeginEditing(notification:)), name: UITextView.textDidBeginEditingNotification, object: nil)
        NotificationCenter.default.addObserver(self, selector: #selector(textViewDidEndEditing(notification:)), name: UITextView.textDidEndEditingNotification, object: nil)
    }

    // MARK: - Destruction -
    deinit { NotificationCenter.default.removeObserver(self) }
}

You're looking for Select which can be used to transform\project the input sequence:

IEnumerable<string> strings = integers.Select(i => i.ToString());

Everything has many properties and behaviours so take whatever object you want TV, Mobile, Car, Human or anything.

Abstraction:

1. Process of picking the essence of an object you really need
2. In other words, pick the properties you need from the object Example:
   a. TV - Sound, Visuals, Power Input, Channels Input.
   b. Mobile - Button/Touch screen, power button, volume button, sim port.
   c. Car - Steering, Break, Clutch, Accelerator, Key Hole.
   d. Human - Voice, Body, Eye Sight, Hearing, Emotions.

Encapsulation:

1. Process of hiding the details of an object you don't need
2. In other words, hide the properties and operations you don't need from the object but are required for the object to work properly Example:
   a. TV - Internal and connections of Speaker, Display, Power distribution b/w components, Channel mechanism.
   b. Mobile - How the input is parsed and processed, How pressing a button on/off or changes volumes, how sim will connect to service providers.
   c. Car - How turning steering turns the car, How break slow or stops the car, How clutch works, How accelerator increases speed, How key hole switch on/of the car.
   d. Human - How voice is produced, What's inside the body, How eye sight works, How hearing works, How emotions generate and effect us.

ABSTRACT everything you need and ENCAPSULATE everything you don't need ;)

None of the above helped for me.

You are testing against the string minus the last character:

>>> '"xxx"'[:-1]
'"xxx'

Note how the last character, the ", is not part of the output of the slice.

I think you wanted just to test against the last character; use [-1:] to slice for just the last element.

However, there is no need to slice here; just use str.startswith() and str.endswith() directly.

Use datetime.datetime.fromtimestamp:

>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'

%f directive is only supported by datetime.datetime.strftime, not by time.strftime.

UPDATE Alternative using %, str.format:

>>> import time
>>> s, ms = divmod(1236472051807, 1000)  # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'

Google has recently made public its internal Collaboratory project (link here). You can start a notebook in the same way as starting a Google Sheet or Google Doc, and then simply share the notebook or add collaborators..

For now, this is the easiest way for me.

When calling java use the -Xmx Flag for example -Xmx512m for 512 megs for the heap size. You may also want to consider the -xms flag to start the heap larger if you are going to have it grow right from the start. The default size is 128megs.

Here is my quick implementation for swift 4:

extension UITextField {
    func placeholderColor(_ color: UIColor){
        var placeholderText = ""
        if self.placeholder != nil{
            placeholderText = self.placeholder!
        }
        self.attributedPlaceholder = NSAttributedString(string: placeholderText, attributes: [NSAttributedStringKey.foregroundColor : color])
    }
}

use like:

streetTextField?.placeholderColor(AppColor.blueColor)

hope it helps someone!

the steps I followed are:

1. close Android Studio (or IntelliJ IDEA)
2. in your project's directory:
   1. delete .idea directory
   2. delete .gradle directory
   3. delete all .iml files
      • find . | grep -e .iml$ | xargs rm
3. use Android Studio to re-open the directory as a project

Terminal commands:

# close Android Studio
cd "your project's directory"
rm -rf ./.idea
rm -rf ./.gradle
find . | grep -e .iml$ | xargs rm
# use Android Studio to re-open the directory as a project

This works:

$('img').bind('contextmenu', function(e) {
    return false;
}); 

Or for newer jQuery:

$('#nearestStaticContainer').on('contextmenu', 'img', function(e){ 
  return false; 
});

Latest version of angular (7.2 +) now has the option to pass additional information using NavigationExtras.

Home component

import {
  Router,
  NavigationExtras
} from '@angular/router';
const navigationExtras: NavigationExtras = {
  state: {
    transd: 'TRANS001',
    workQueue: false,
    services: 10,
    code: '003'
  }
};
this.router.navigate(['newComponent'], navigationExtras);

newComponent

test: string;
constructor(private router: Router) {
  const navigation = this.router.getCurrentNavigation();
  const state = navigation.extras.state as {
    transId: string,
    workQueue: boolean,
    services: number,
    code: string
  };
  this.test = "Transaction Key:" + state.transId + "<br /> Configured:" + state.workQueue + "<br /> Services:" + state.services + "<br /> Code: " + state.code;
}

Output

Hope this would help!

Try this:

MyContext Context = new MyContext(); 
Context.YourEntity.Add(obj);
Context.SaveChanges();
int ID = obj._ID;

One important thing to mention as well is the security improvement that comes with the package-lock file. Since it keeps all the hashes of the packages if someone would tamper with the public npm registry and change the source code of a package without even changing the version of the package itself it would be detected by the package-lock file.

Then try javac again - if this works you'll need to permanently modify your environment variables to have PATH include the JDK too.

Finally managed to solve all the issues, so I'll answer my own question. These are the settings/files I've used to manage to get my particular problem(s) solved;

The client's keystore is a PKCS#12 format file containing

1. The client's public certificate (in this instance signed by a self-signed CA)
2. The client's private key

To generate it I used OpenSSL's pkcs12 command, for example;

openssl pkcs12 -export -in client.crt -inkey client.key -out client.p12 -name "Whatever"

Tip: make sure you get the latest OpenSSL, not version 0.9.8h because that seems to suffer from a bug which doesn't allow you to properly generate PKCS#12 files.

This PKCS#12 file will be used by the Java client to present the client certificate to the server when the server has explicitly requested the client to authenticate. See the Wikipedia article on TLS for an overview of how the protocol for client certificate authentication actually works (also explains why we need the client's private key here).

The client's truststore is a straight forward JKS format file containing the root or intermediate CA certificates. These CA certificates will determine which endpoints you will be allowed to communicate with, in this case it will allow your client to connect to whichever server presents a certificate which was signed by one of the truststore's CA's.

To generate it you can use the standard Java keytool, for example;

keytool -genkey -dname "cn=CLIENT" -alias truststorekey -keyalg RSA -keystore ./client-truststore.jks -keypass whatever -storepass whatever
keytool -import -keystore ./client-truststore.jks -file myca.crt -alias myca

Using this truststore, your client will try to do a complete SSL handshake with all servers who present a certificate signed by the CA identified by myca.crt.

The files above are strictly for the client only. When you want to set-up a server as well, the server needs its own key- and truststore files. A great walk-through for setting up a fully working example for both a Java client and server (using Tomcat) can be found on this website.

Issues/Remarks/Tips

1. Client certificate authentication can only be enforced by the server.
2. (Important!) When the server requests a client certificate (as part of the TLS handshake), it will also provide a list of trusted CA's as part of the certificate request. When the client certificate you wish to present for authentication is not signed by one of these CA's, it won't be presented at all (in my opinion, this is weird behaviour, but I'm sure there's a reason for it). This was the main cause of my issues, as the other party had not configured their server properly to accept my self-signed client certificate and we assumed that the problem was at my end for not properly providing the client certificate in the request.
3. Get Wireshark. It has great SSL/HTTPS packet analysis and will be a tremendous help debugging and finding the problem. It's similar to -Djavax.net.debug=ssl but is more structured and (arguably) easier to interpret if you're uncomfortable with the Java SSL debug output.

4. It's perfectly possible to use the Apache httpclient library. If you want to use httpclient, just replace the destination URL with the HTTPS equivalent and add the following JVM arguments (which are the same for any other client, regardless of the library you want to use to send/receive data over HTTP/HTTPS):

   -Djavax.net.debug=ssl
   -Djavax.net.ssl.keyStoreType=pkcs12
   -Djavax.net.ssl.keyStore=client.p12
   -Djavax.net.ssl.keyStorePassword=whatever
   -Djavax.net.ssl.trustStoreType=jks
   -Djavax.net.ssl.trustStore=client-truststore.jks
   -Djavax.net.ssl.trustStorePassword=whatever
