Programs & Examples On #Interrupt

Traps and interrupts are closely related. Traps are a type of exception, and exceptions are similar to interrupts.

Intel x86 defines two overlapping categories, vectored events (interrupts vs exceptions), and exception classes (faults vs traps vs aborts).

All of the quotes in this post are from the April 2016 version of the Intel Software Developer Manual. For the (definitive and complex) x86 perspective, I recommend reading the SDM's chapter on Interrupt and Exception handling.

Vectored Events

Vectored Events (interrupts and exceptions) cause the processor to jump into an interrupt handler after saving much of the processor's state (enough such that execution can continue from that point later).

Exceptions and interrupts have an ID, called a vector, that determines which interrupt handler the processor jumps to. Interrupt handlers are described within the Interrupt Descriptor Table.

Interrupts

Interrupts occur at random times during the execution of a program, in response to signals from hardware. System hardware uses interrupts to handle events external to the processor, such as requests to service peripheral devices. Software can also generate interrupts by executing the INT n instruction.

Exceptions

Exceptions occur when the processor detects an error condition while executing an instruction, such as division by zero. The processor detects a variety of error conditions including protection violations, page faults, and internal machine faults.

Exception Classifications

Exceptions are classified as faults, traps, or aborts depending on the way they are reported and whether the instruction that caused the exception can be restarted without loss of program or task continuity.

Summary: traps increment the instruction pointer, faults do not, and aborts 'explode'.

Trap

A trap is an exception that is reported immediately following the execution of the trapping instruction. Traps allow execution of a program or task to be continued without loss of program continuity. The return address for the trap handler points to the instruction to be executed after the trapping instruction.

Fault

A fault is an exception that can generally be corrected and that, once corrected, allows the program to be restarted with no loss of continuity. When a fault is reported, the processor restores the machine state to the state prior to the beginning of execution of the faulting instruction. The return address (saved contents of the CS and EIP registers) for the fault handler points to the faulting instruction, rather than to the instruction following the faulting instruction.

Example: A page fault is often recoverable. A piece of an application's address space may have been swapped out to disk from ram. The application will trigger a page fault when it tries to access memory that was swapped out. The kernel can pull that memory from disk to ram, and hand control back to the application. The application will continue where it left off (at the faulting instruction that was accessing swapped out memory), but this time the memory access should succeed without faulting.

An illegal-instruction fault handler that emulates floating-point or other missing instructions would have to manually increment the return address to get the trap-like behaviour it needs, after seeing if the faulting instruction was one it could handle. x86 #UD is a "fault", not a "trap". (The handler would need a pointer to the faulting instruction to figure out which instruction it was.)

Abort

An abort is an exception that does not always report the precise location of the instruction causing the exception and does not allow a restart of the program or task that caused the exception. Aborts are used to report severe errors, such as hardware errors and inconsistent or illegal values in system tables.

Edge Cases

Software invoked interrupts (triggered by the INT instruction) behave in a trap-like manner. The instruction completes before the processor saves its state and jumps to the interrupt handler.

Yet another custom implementation that doesn't require support table:

drop function if exists base64_encode;
create function base64_encode(_data blob)
returns text
begin
    declare _alphabet char(64) default 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/';
    declare _lim int unsigned default length(_data);
    declare _i int unsigned default 0;
    declare _chk3 char(6) default '';
    declare _chk3int int default 0;
    declare _enc text default '';

    while _i < _lim do
        set _chk3 = rpad(hex(binary substr(_data, _i + 1, 3)), 6, '0');
        set _chk3int = conv(_chk3, 16, 10);
        set _enc = concat(
            _enc

    return _enc;

        if (_chr1byte > -1)
        then
            set _chk4int = (_chk4int << 6) | _chr1byte;
            set _chk4int_bits = _chk4int_bits + 6;

            if (_chk4int_bits = 24 or _i = _lim-1)
            then
                if (_i = _lim-1 and _chk4int_bits != 24)
                then
                    set _chk4int = _chk4int << 0;

                set _dec = concat(
                    _dec
                    ,                        char((_chk4int >> (_chk4int_bits -  8)) & 0xff)

                );
                set _chk4int = 0;
                set _chk4int_bits = 0;
            end if;
        end if;
        set _i = _i + 1;
    end while;

    return substr(_dec, 1, length(_dec) - _rem);

Gist

You should convert charset after decoding: convert(base64_decode(base64_encode('????')) using utf8)

You don't need to use arrays.

JSON values can be arrays, objects, or primitives (numbers or strings).

You can write JSON like this:

{ 
    "stuff": {
        "onetype": [
            {"id":1,"name":"John Doe"},
            {"id":2,"name":"Don Joeh"}
        ],
        "othertype": {"id":2,"company":"ACME"}
    }, 
    "otherstuff": {
        "thing": [[1,42],[2,2]]
     }
}

You can use it like this:

obj.stuff.onetype[0].id
obj.stuff.othertype.id
obj.otherstuff.thing[0][1]  //thing is a nested array or a 2-by-2 matrix.
                            //I'm not sure whether you intended to do that.

What about using checkout command :

  git diff --stat "$branch"
  git checkout --merge "$branch" "$file"
  git diff --stat "$branch"

Is a good idea named the functions with commun alias on the first words for filtre the name with LIKE Example with public schema in Postgresql 9.4, be sure to replace with his scheme

SELECT routine_name 
FROM information_schema.routines 
WHERE routine_type='FUNCTION' 
  AND specific_schema='public'
  AND routine_name LIKE 'aliasmyfunctions%';

    setContentView(R.layout.activity_main);

    status = (TextView) findViewById(R.id.main_status);
    status.setGravity(Gravity.CENTER);

        zipFile = new File(destination, "BlueBoxnew.zip");
        try {
            Unzipper.unzip(zipFile, destination);

        } else {
            result = true;

Note x += y is not the same as x = x + y in some situations where an additional operator is included because of the operator precedence combined with the fact that the right hand side is always evaluated first, e.g.

>>> x = 2
>>> x += 2 and 1
>>> x
3

>>> x = 2
>>> x = x + 2 and 1
>>> x
1

Note the first case expand to:

>>> x = 2
>>> x = x + (2 and 1)
>>> x
3

You are more likely to encounter this in the 'real world' with other operators, e.g.

x *= 2 + 1 == x = x * (2 + 1) != x = x * 2 + 1

Are the classes imported? Try pressing CTRL + SHIFT + O to resolve the imports. If this does not work you need to include the application servers runtime libraries.

I was handling a bigint datatype to be shown in a DataGridView and made it like this

something = (int)(Int64)data_reader[0];

You may want to use SHA-1 instead of MD5, as MD5 is considered broken.

You can read more about MD5 vulnerabilities in this Wikipedia article.

I personally use interfaces for my models, There hoewver are 3 schools regarding this question, and choosing one is most often based on your requirements:

1- Interfaces:

interface is a virtual structure that only exists within the context of TypeScript. The TypeScript compiler uses interfaces solely for type-checking purposes. Once your code is transpiled to its target language, it will be stripped from its interfaces - JavaScript isn’t typed.

interface User {
 id: number;
 username: string;
}
// inheritance
interface UserDetails extends User {
 birthdate: Date;
 biography?: string;  // use the '?' annotation to mark this property as optionnal
}

Mapping server response to an interface is straight forward if you are using HttpClient from HttpClientModule if you are using Angular 4.3.x and above.

getUsers() :Observable<User[]> {
 return this.http.get<User[]>(url); // no need for '.map((res: Response) => res.json())' 
}

when to use interfaces:

• You only need the definition for the server data without introducing additional overhead for the final output.
• You only need to transmit data without any behaviors or logic (constructor initialization, methods)
• You do not instantiate/create objects from your interface very often
  • Using simple object-literal notationlet instance: FooInterface = { ... };, you risk having semi-instances all over the place.
  • That doesn't enforce the constraints given by a class ( constructor or initialization logic, validation, encapsulation of private fields...Etc)
• You need to define contracts/configurations for your systems (global configurations)

2- Classes:

A class defines the blueprints of an object. They express the logic, methods, and properties these objects will inherit.

class User {
 id: number;
 username: string;
 constructor(id :number, username: string)  {
  this.id = id;
  this.username = username.replace(/^\s+|\s+$/g, ''); // trim whitespaces and new lines
 }
}
// inheritance
class UserDetails extends User {
 birthdate: Date;
 biography?: string;  
 constructor(id :number, username: string, birthdate:Date, biography? :string )  {
   super(id,username);
  this.birthdate = ...;
 }
}

when to use classes:

• You instantiate your class and change the instances state over time.
• Instances of your class will need methods to query or mutate its state
• When you want to associate behaviors with data more closely;
• You enforce constraints on the creation of your instaces.
• If you only write a bunch of properties assignments in your class, you might consider using a type instead.

2- Types:

With the latest versions of typescript, interfaces and types becoming more similar. types do not express logic or state inside your application. It is best to use types when you want to describe some form of information. They can describe varying shapes of data, ranging from simple constructs like strings, arrays, and objects. Like interfaces, types are only virtual structures that don't transpile to any javascript, they just help the compiler making our life easier.

type User = {
 id: number;
 username: string;
}
// inheritance
type UserDetails = User & {
  birthDate :Date;
  biography?:string;
}

when to use types:

• pass it around as concise function parameters
• describe a class constructor parameters
• document small or medium objects coming in or out from an API.
• they don't carry state nor behavior

Use plain javascript methods

$x10Device = this.dataset("x10");

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']
>>> [word for word in words if not word.islower() and not word.isupper()]
['The', 'Fox', 'Lazy']

From the documentation:

int getCellType() Deprecated. POI 3.15. Will return a CellType enum in the future.

Return the cell type. Will return CellType in version 4.0 of POI. For forwards compatibility, do not hard-code cell type literals in your code.

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.

Working tree

Your working tree are the files that you are currently working on.

Git index

• The git "index" is where you place files you want commit to the git repository.

• The index is also known as cache, directory cache, current directory cache, staging area, staged files.

• Before you "commit" (checkin) files to the git repository, you need to first place the files in the git "index".

• The index is not the working directory: you can type a command such as git status, and git will tell you what files in your working directory have been added to the git index (for example, by using the git add filename command).

• The index is not the git repository: files in the git index are files that git would commit to the git repository if you used the git commit command.

This is what I've used recently.

Hope it helps somewhere.

Here is how I would do it:

public String cleanDecimalString(String input, boolean americanFormat) {
    if (americanFormat)
        return input.replaceAll(",", "");
    else
        return input.replaceAll(".", "");
}

Obviously, if this were going in production code, it wouldn't be that simple.

I see no issue with simply removing the commas from the String.

I've created a small plugin (available on NuGet) that allows you to add any (if supported by your terminal) color to your console output, without the limitations of the classic solutions.

It works by extending the String object and the syntax is very simple:

"colorize me".Pastel("#1E90FF");

Both foreground and background colors are supported.

First check your listener is on or off. Go to net manager then Local -> service naming -> orcl. Then change your HOST NAME and put your PC name. Now go to LISTENER and change the HOST and put your PC name.

There is a method update on BaseQuery object in SQLAlchemy, which is returned by filter_by.

num_rows_updated = User.query.filter_by(username='admin').update(dict(email='[email protected]')))
db.session.commit()

The advantage of using update over changing the entity comes when there are many objects to be updated.

If you want to give add_user permission to all the admins,

rows_changed = User.query.filter_by(role='admin').update(dict(permission='add_user'))
db.session.commit()

Notice that filter_by takes keyword arguments (use only one =) as opposed to filter which takes an expression.

I had randomly gotten this idea just a while ago. Using a While loop with string splicing and string search can work, even for overlapping strings.

findin = "algorithm alma mater alison alternation alpines"
search = "al"
inx = 0
num_str = 0

while True:
    inx = findin.find(search)
    if inx == -1: #breaks before adding 1 to number of string
        break
    inx = inx + 1
    findin = findin[inx:] #to splice the 'unsearched' part of the string
    num_str = num_str + 1 #counts no. of string

if num_str != 0:
    print("There are ",num_str," ",search," in your string.")
else:
    print("There are no ",search," in your string.")

I'm an amateur in Python Programming (Programming of any language, actually), and am not sure what other issues it could have, but I guess it's working fine?

I guess lower() could be used somewhere in it too if needed.

I have done this before, I think you need to remove the ActionResult. Make it a void and remove the return View(MyView). this is the solution

For security reasons, you can't move the mouse pointer with javascript, nor simulate a click with it.

What is it that you are trying to accomplish?

You can Use the tool : Eclipse Memory Analyzer Tool http://www.eclipse.org/mat/ .

It is very useful.

Try this to read using Pandas:

pd.read_csv('u.item', sep='|', names=m_cols, encoding='latin-1')

This will solve your problem in macOS:

pico ~/.bash_profile

export ANDROID_HOME=/Users/$USER/Library/Android/sdk
export ANDROID_SDK_HOME=/Users/$USER/Library/Android/sdk
export ANDROID_AVD_HOME=/Users/$USER/.android/avd
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$ANDROID_AVD_HOME

source ~/.bash_profile

Enums in C++ are like integers masked by the names you give them, when you declare your enum-values (this is not a definition only a hint how it works).

But there are two errors in your code:

1. Spell enum all lower case
2. You don't need the Days. before Saturday.
3. If this enum is declared in a class, then use if (day == YourClass::Saturday){}

If someone finds this question like me, here are my performance tests of proposed methods:

Python 2.7.8

In [1]: %timeit ([1]*1000000).insert(0, 0)
100 loops, best of 3: 4.62 ms per loop

In [2]: %timeit ([1]*1000000)[0:0] = [0]
100 loops, best of 3: 4.55 ms per loop

In [3]: %timeit [0] + [1]*1000000
100 loops, best of 3: 8.04 ms per loop

As you can see, insert and slice assignment are as almost twice as fast than explicit adding and are very close in results. As Raymond Hettinger noted insert is more common option and I, personally prefer this way to prepend to list.

Please try to remove the preceeding spaces before EOF:-

/var/mail -s "$SUBJECT" "$EMAIL" <<-EOF

Using <tab> instead of <spaces> for ident AND using <<-EOF works fine.

The "-" removes the <tabs>, not <spaces>, but at least this works.

Just create a multi-line comment around it. When you want it back, just erase the comment tags.

For example, <!-- Stuff to comment out or make inactive -->

for wav format below audio setting

NSDictionary *audioSetting = [NSDictionary dictionaryWithObjectsAndKeys:
                              [NSNumber numberWithFloat:44100.0],AVSampleRateKey,
                              [NSNumber numberWithInt:2],AVNumberOfChannelsKey,
                              [NSNumber numberWithInt:16],AVLinearPCMBitDepthKey,
                              [NSNumber numberWithInt:kAudioFormatLinearPCM],AVFormatIDKey,
                              [NSNumber numberWithBool:NO], AVLinearPCMIsFloatKey, 
                              [NSNumber numberWithBool:0], AVLinearPCMIsBigEndianKey,
                              [NSNumber numberWithBool:NO], AVLinearPCMIsNonInterleaved,
                              [NSData data], AVChannelLayoutKey, nil];

ref: http://objective-audio.jp/2010/09/avassetreaderavassetwriter.html

There is also another solution to the problem by implementing a layer-list that will act as the background for the LinearLayoout.

Add background_with_shadow.xml file to res/drawable. Containing:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item >
        <shape 
            android:shape="rectangle">
        <solid android:color="@android:color/darker_gray" />
        <corners android:radius="5dp"/>
        </shape>
    </item>
    <item android:right="1dp" android:left="1dp" android:bottom="2dp">
        <shape 
            android:shape="rectangle">
        <solid android:color="@android:color/white"/>
        <corners android:radius="5dp"/>
        </shape>
    </item>
</layer-list>

Then add the the layer-list as background in your LinearLayout.

<LinearLayout
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/background_with_shadow"/>

I have just copied UUID toString() method and just updated it to remove "-" from it. It will be much more faster and straight forward than any other solution

public String generateUUIDString(UUID uuid) {
    return (digits(uuid.getMostSignificantBits() >> 32, 8) +
            digits(uuid.getMostSignificantBits() >> 16, 4) +
            digits(uuid.getMostSignificantBits(), 4) +
            digits(uuid.getLeastSignificantBits() >> 48, 4) +
            digits(uuid.getLeastSignificantBits(), 12));
}

/** Returns val represented by the specified number of hex digits. */
private String digits(long val, int digits) {
    long hi = 1L << (digits * 4);
    return Long.toHexString(hi | (val & (hi - 1))).substring(1);
}

Usage:

generateUUIDString(UUID.randomUUID())

Another implementation using reflection

public String generateString(UUID uuid) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {

    if (uuid == null) {
        return "";
    }

    Method digits = UUID.class.getDeclaredMethod("digits", long.class, int.class);
    digits.setAccessible(true);

    return ( (String) digits.invoke(uuid, uuid.getMostSignificantBits() >> 32, 8) +
            digits.invoke(uuid, uuid.getMostSignificantBits() >> 16, 4) +
            digits.invoke(uuid, uuid.getMostSignificantBits(), 4) +
            digits.invoke(uuid, uuid.getLeastSignificantBits() >> 48, 4) +
            digits.invoke(uuid, uuid.getLeastSignificantBits(), 12));

}

Nvm Nvm is a script-based node version manager. You can install it easily with a curl and bash one-liner as described in the documentation. It's also available on Homebrew.

Assuming you have successfully installed nvm. The following will install the latest version of node.

 nvm install node --reinstall-packages-from=node

The last option installs all global npm packages over to your new version. This way packages like mocha and node-inspector keep working.

N N is an npm-based node version manager. You can install it by installing first some version of node and then running npm install -g n.

Assuming you have successfully installed n. The following will install the latest version of node.

sudo n latest

Homebrew Homebrew is one of the two popular package managers for Mac. Assuming you have previously installed node with brew install node. You can get up-to-date with formulae and upgrade to the latest Node.js version with the following.

1 brew update
2 brew upgrade node

MacPorts MacPorts is the another package manager for Mac. The following will update the local ports tree to get access to updated versions. Then it will install the latest version of Node.js. This works even if you have previous version of the package installed.

1 sudo port selfupdate
2 sudo port install nodejs-devel

The closest approach I can think of is NULLIF:

SELECT 
    ISNULL(NULLIF(O.ShipName, C.CompanyName), 1),
    O.ShipName,      
    C.CompanyName,
    O.OrderId
FROM [Northwind].[dbo].[Orders] O
INNER JOIN [Northwind].[dbo].[Customers] C
ON C.CustomerId = O.CustomerId

GO

NULLIF returns the first expression if the two expressions are not equal. If the expressions are equal, NULLIF returns a null value of the type of the first expression.

So, above query will return 1 for records in which that columns are equal, the first expression otherwise.

Getting the data after the hashmark in a query string is simple. Here is an example used for when a client accesses a glossary of terms from a book. It takes the name anchor delivered (#tesla), and delivers the client to that term and highlights the term and its description in blue so its easy to see.

A. setup your strings with a div id, so the name anchor goes where its supposed to and the javascript can change the text colors

<div id="tesla">Tesla</div>
<div id="tesla1">An energy company</div>

B. Use Javascript to do the heavy work, on the server side, inserted in your PHP page, or wherever..

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>

C. I am launching the java function automatically when the page is loaded.

<script>
$( document ).ready(function() {

D. get the anchor (#tesla) from the url received by the server

var myhash1 = $(location).attr('hash'); //myhash1 == #tesla

E. trim the hash sign off of it

myhash1 = myhash1.substr(1)  //myhash1 == tesla

F. I need to highlight the term and the description so i create a new var

var myhash2 = '1';
myhash2 = myhash1.concat(myhash2); //myhash2 == tesla1

G. Now I can manipulate the text color for the term and description

var elem = document.getElementById(myhash1);
elem.style.color = 'blue';
elem = document.getElementById(myhash2);
elem.style.color = 'blue';
});
</script>

H. This works. client clicks link on client side (xyz.com#tesla) and goes right to the term. the term and the description are highlighted in blue by javascript for quick reading .. all other entries left in black..

For example to execute from terminal (Ubuntu Linux) or even (Windows console) a java file called filex.jar use this command:

java -jar filex.jar

The file will execute in terminal.

My advice is to not (try to) implement __iob_func.

While fixing these errors:

libpngd.v110.lib(pngrutil.obj) : error LNK2001: unresolved external symbol ___iob_func curllib.v110.lib(mprintf.obj) : error LNK2001: unresolved external symbol ___iob_func

I tried the other answers' solutions, but in the end, returning a FILE* C-array doesn't match up with an array of Windows' internal IOB structs. @Volker is right that it'll never work for more than one of stdin, stdout or stderr.

If a library actually USES one of those streams, it will crash. As long as your program doesn't cause the lib to use them, you'll never know. For example, png_default_error writes to stderr when the CRC doesn't match in the PNG's metadata. (Normally not a crash-worthy issue)

Conclusion: It's not possible to mix VS2012 (Platform Toolset v110/v110_xp) and VS2015+ libraries, if they use stdin, stdout and/or stderr.

Solution: Recompile your libraries that have __iob_func unresolved symbols with your current version of VS and a matching Platform Toolset.

        public static async Task Post<T>(string url, T contentValue)
        {

Example for delete:

await HttpHelper.Delete($"/api/values/{id}");

Example to get a list:

Example to get only one:

ClaimTerm processedClaimImage = await HttpHelper.Get<ClaimTerm>($"/api/values/{id}");

So hopefully this helps someone out.

The new answer that Reuben Scratton gave is great and really efficient, but it really only works if you set your windowSoftInputMode to adjustResize. If you set it to adjustPan, it's still not possible to detect whether or not the keyboard is visible using his code snippet. To work around this, I made this tiny modification to the code above.

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
    Rect r = new Rect();
    //r will be populated with the coordinates of your view that area still visible.
    activityRootView.getWindowVisibleDisplayFrame(r);
   
    int heightDiff = activityRootView.getRootView().getHeight() - r.height();
    if (heightDiff > 0.25*activityRootView.getRootView().getHeight()) { // if more than 25% of the screen, its probably a keyboard...
        ... do something here
    }
 }
}); 

Type Services.msc in run panel of windows run window. It will list all the windows services in our system. Now we need to start Asp .net State service as show in the image.

Your issue will get resolved.

Try MtPutty, you can automate the ssh login in it. Its a great tool especially if you need to login to multiple servers many times. Try it here

Another tool worth trying is TeraTerm. Its really easy to use for the ssh automation stuff. You can get it here. But my favorite one is always MtPutty.

Bootstrap Version 3.x

As always, read Bootstrap's great documentation:

3.x Docs: https://getbootstrap.com/docs/3.3/css/#grid-nesting

Make sure the parent level row is inside of a .container element. Whenever you'd like to nest rows, just open up a new .row inside of your column.

Here's a simple layout to work from:

<div class="container">
    <div class="row">
        <div class="col-xs-6">
            <div class="big-box">image</div>
        </div>
        <div class="col-xs-6">
            <div class="row">
                <div class="col-xs-6"><div class="mini-box">1</div></div>
                <div class="col-xs-6"><div class="mini-box">2</div></div>
                <div class="col-xs-6"><div class="mini-box">3</div></div>
                <div class="col-xs-6"><div class="mini-box">4</div></div>
            </div>
        </div>
    </div>
</div>

Bootstrap Version 4.0

4.0 Docs: http://getbootstrap.com/docs/4.0/layout/grid/#nesting

Here's an updated version for 4.0, but you should really read the entire docs section on the grid so you understand how to leverage this powerful feature

<div class="container">
  <div class="row">
    <div class="col big-box">
      image
    </div>

    <div class="col">
      <div class="row">
        <div class="col mini-box">1</div>
        <div class="col mini-box">2</div>
      </div>
      <div class="row">
        <div class="col mini-box">3</div>
        <div class="col mini-box">4</div>
      </div>
    </div>

  </div>

Which will look like this (with a little bit of added styling):

Actually I use _ method names when I need to differ between parent and child class names. I've read some codes that used this way of creating parent-child classes. As an example I can provide this code:

class ThreadableMixin:
   def start_worker(self):
       threading.Thread(target=self.worker).start()

   def worker(self):
      try:
        self._worker()
    except tornado.web.HTTPError, e:
        self.set_status(e.status_code)
    except:
        logging.error("_worker problem", exc_info=True)
        self.set_status(500)
    tornado.ioloop.IOLoop.instance().add_callback(self.async_callback(self.results))

...

and the child that have a _worker method

class Handler(tornado.web.RequestHandler, ThreadableMixin):
   def _worker(self):
      self.res = self.render_string("template.html",
        title = _("Title"),
        data = self.application.db.query("select ... where object_id=%s", self.object_id)
    )

...

I was facing this error in VS code because I was using VS code git extension. It saves my git credentials on Linux key-ring. While I wanted to git pull from another account which has access to the repository. The most simple solution is to open the Linux shell (not the one integrated in VS code) and then run:

git pull origin master

This time, it will ask you the username and password of Github.

You can use jquery load for that.

<script type="text/javascript">
$(document).ready(function(e) {
    $('#header').load('name.html',function(){alert('loaded')});
});
</script>

Don't forget to include jquery library befor above code.

In my case, the problem was I was linking to debug python & boost::Python, which requires that the extension be FooLib_d.pyd, not just FooLib.pyd; renaming the file or updating CMakeLists.txt properties fixed the error.

If you need the output in a file you can use a redirect:

curl https://vi.stackexchange.com/ -vs >curl-output.txt 2>&1

Please be sure not to flip the >curl-output.txt and 2>&1, which will not work due to bash's redirection behavior.

How about make clicking the a tag, to click on the file button?

There is more browser support for this, but I use ES6, so if you really want to make it work in older and any browser, try to transpile it using babel, or just simply use ES5:

const aTag = document.getElementById("open-file-uploader");_x000D_
const fileInput = document.getElementById("input-button");_x000D_
aTag.addEventListener("click", () => fileInput.click());

#input-button {_x000D_
  position: abosulte;_x000D_
  width: 1px;_x000D_
  height: 1px;_x000D_
  clip: rect(1px 1px 1px 1px);_x000D_
  clip: rect(1px, 1px, 1px, 1px);_x000D_
}

<a href="#" id="open-file-uploader">Open file uploader</a>_x000D_
<input type="file" id="input-button" />

Here is what I use, seems pretty clean:

import subprocess

def count_file_lines(file_path):
    """
    Counts the number of lines in a file using wc utility.
    :param file_path: path to file
    :return: int, no of lines
    """
    num = subprocess.check_output(['wc', '-l', file_path])
    num = num.split(' ')
    return int(num[0])

UPDATE: This is marginally faster than using pure python but at the cost of memory usage. Subprocess will fork a new process with the same memory footprint as the parent process while it executes your command.

Use Array.prototype.filter instead of forEach:

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a', 'b', 'c', 'b', 'a', 'e'];
review = review.filter(item => item !== 'a');
log(review);

I hope this helps:

import string

alphas = list(string.ascii_letters[:26])
for chr in alphas:
 print(chr)

This worked for me.

make sure the extension should by on pg_catalog and not in your schema...

You probably don't want to do this:

#include "client.cpp"

A *.cpp file will have been compiled by the compiler as part of your build. By including it in other files, it will be compiled again (and again!) in every file in which you include it.

Now here's the thing: You are guarding it with #ifndef SOCKET_CLIENT_CLASS, however, each file that has #include "client.cpp" is built independently and as such will find SOCKET_CLIENT_CLASS not yet defined. Therefore it's contents will be included, not #ifdef'd out.

If it contains any definitions at all (rather than just declarations) then these definitions will be repeated in every file where it's included.

Use something like this:

page1.php

<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>

Any other PHP page:

<?php
session_start();
echo $_SESSION['myValue'];
?>

A few notes to keep in mind though: You need to call session_start() BEFORE any output, HTML, echos - even whitespace.

You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.

The setting of the variable itself can be done in one of a number of ways:

$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];

And if you want to check if the variable is set before getting a potential error, use something like this:

if(!empty($_SESSION['myValue'])
{
    echo $_SESSION['myValue'];
}
else
{
    echo "Session not set yet.";
}

hi i got the same problem.. add 0.71 to excel cell width value and give that value to the

$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);

eg: A Column width = 3.71 (excel value)

give column width = 4.42

will give the output file with same cell width.

$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(4.42);

hope this help

If you forgot to add the repository HTTPS link then put it with git push <repo HTTPS>

This has been really helpful. Here is my implementation for any given table:

For multiple classes in the same js file, extending Component from @wordpress/element, you can do that :

// classes.js
import { Component } from '@wordpress/element';

const Class1 = class extends Component {
}

const Class2 = class extends Component {
}

export { Class1, Class2 }

And import them in another js file :

import { Class1, Class2 } from './classes';

Well, the above answer is correct, auto_now_add and auto_now would do it, but it would be better to make an abstract class and use it in any model where you require created_at and updated_at fields.

class TimeStampMixin(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

Now anywhere you want to use it you can do a simple inherit and you can use timestamp in any model you make like.

class Posts(TimeStampMixin):
    name = models.CharField(max_length=50)
    ...
    ...

In this way, you can leverage object-oriented reusability, in Django DRY(don't repeat yourself)

Documented couple of design issues with this in a comment above. Short story, in Oracle, you need to limit the results manually when you have large tables and/or tables with same column names (and you don't want to explicit type them all out and rename them all). Easy solution is to figure out your breakpoint and limit that in your query. Or you could also do this in the inner query if you don't have the conflicting column names constraint. E.g.

WHERE m_api_log.created_date BETWEEN TO_DATE('10/23/2015 05:00', 'MM/DD/YYYY HH24:MI') 
                                 AND TO_DATE('10/30/2015 23:59', 'MM/DD/YYYY HH24:MI')  

will cut down the results substantially. Then you can ORDER BY or even do the outer query to limit rows.

Also, I think TOAD has a feature to limit rows; but, not sure that does limiting within the actual query on Oracle. Not sure.

its very true on oracle as well as sql is "users" is a reserved words just change it , it will serve u the best if u like change it to this

UPDATE system_info set field_value = 'NewValue' 

FROM system_users users JOIN system_info info ON users.role_type = info.field_desc where users.user_name = 'uname'

I have implemented a wrapper if anyone would like to specify variable types.

import functools
    
def type_check(func):

    @functools.wraps(func)
    def check(*args, **kwargs):
        for i in range(len(args)):
            v = args[i]
            v_name = list(func.__annotations__.keys())[i]
            v_type = list(func.__annotations__.values())[i]
            error_msg = 'Variable `' + str(v_name) + '` should be type ('
            error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ')'
            if not isinstance(v, v_type):
                raise TypeError(error_msg)

        result = func(*args, **kwargs)
        v = result
        v_name = 'return'
        v_type = func.__annotations__['return']
        error_msg = 'Variable `' + str(v_name) + '` should be type ('
        error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ')'
        if not isinstance(v, v_type):
                raise TypeError(error_msg)
        return result

    return check

Use it as:

@type_check
def test(name : str) -> float:
    return 3.0

@type_check
def test2(name : str) -> str:
    return 3.0

>> test('asd')
>> 3.0

>> test(42)
>> TypeError: Variable `name` should be type (<class 'str'>) but instead is type (<class 'int'>)

>> test2('asd')
>> TypeError: Variable `return` should be type (<class 'str'>) but instead is type (<class 'float'>)

EDIT

The code above does not work if any of the arguments' (or return's) type is not declared. The following edit can help, on the other hand, it only works for kwargs and does not check args.

def type_check(func):

    @functools.wraps(func)
    def check(*args, **kwargs):
        for name, value in kwargs.items():
            v = value
            v_name = name
            if name not in func.__annotations__:
                continue
                
            v_type = func.__annotations__[name]

            error_msg = 'Variable `' + str(v_name) + '` should be type ('
            error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ') '
            if not isinstance(v, v_type):
                raise TypeError(error_msg)

        result = func(*args, **kwargs)
        if 'return' in func.__annotations__:
            v = result
            v_name = 'return'
            v_type = func.__annotations__['return']
            error_msg = 'Variable `' + str(v_name) + '` should be type ('
            error_msg += str(v_type) + ') but instead is type (' + str(type(v)) + ')'
            if not isinstance(v, v_type):
                    raise TypeError(error_msg)
        return result

    return check

As far as I know, a forced update like this is not directly possible. You might be able to reduce the DNS downtime by reducing the TTL (Time-To-Live) value of the entries before changing them, if your name server service provider allows that.

Here's a guide for less painful DNS changes.

A fair warning, though - not all name servers between your client and the authoritative (origin) name server will enforce your TTL, they might have their own caching time.

    //best way to deal with this is sqlbulkcopy 
    //but if you dont like it you can do it like this
    //read current sql table in an adapter
    //add rows of datatable , I have mentioned a simple way of it
    //and finally updating changes

    Dim cnn As New SqlConnection("connection string")        
    cnn.Open()
    Dim cmd As New SqlCommand("select * from  sql_server_table", cnn)
    Dim da As New SqlDataAdapter(cmd)       
    Dim ds As New DataSet()
    da.Fill(ds, "sql_server_table")
    Dim cb As New SqlCommandBuilder(da)        

    //for each datatable row
    ds.Tables("sql_server_table").Rows.Add(COl1, COl2)

    da.Update(ds, "sql_server_table")

Tab Control gives nice control in a similar manner to that described in your question.

Also nice, for JavaScript developers, is ESLint Tab Length for using ESLint config.

Or if you're using an .editorconfig for defining project-specific indentation rules, there is EditorConfig

SOAP (communication protocol) for communication between applications. Uses HTTP (port 80) or SMTP ( port 25 or 2525 ), for message negotiation and transmission.

First save all IDs and alter them programmatically to the values you wan't, then remove them from database and then insert them again using something similar:

use [Name.Database]
go
set identity_insert [Test] ON
insert into [dbo].[Test]
           ([Id])
     VALUES
           (2)
set identity_insert [Test] OFF

For bulk insert use:

use [Name.Database]
go
set identity_insert [Test] ON
BULK INSERT [Test]
FROM 'C:\Users\Oscar\file.csv'
WITH (FIELDTERMINATOR = ';',
      ROWTERMINATOR = '\n',
      KEEPIDENTITY)
set identity_insert [Test] OFF

Sample data from file.csv:

2;
3;
4;
5;
6;

If you don't set identity_insert to off you will get the following error:

Cannot insert explicit value for identity column in table 'Test' when IDENTITY_INSERT is set to OFF.

There are some good answers on how to get started on doing this. But there are some things to keep in mind:

• What if the instance is nested inside a large data structure?
• What if also want the class name?
• What if you want to deserialize the instance?
• What if you're using __slots__ instead of __dict__?
• What if you just don't want to do it yourself?

json-tricks is a library (that I made and others contributed to) which has been able to do this for quite a while. For example:

class MyTestCls:
    def __init__(self, **kwargs):
        for k, v in kwargs.items():
            setattr(self, k, v)

cls_instance = MyTestCls(s='ub', dct={'7': 7})

json = dumps(cls_instance, indent=4)
instance = loads(json)

You'll get your instance back. Here the json looks like this:

{
    "__instance_type__": [
        "json_tricks.test_class",
        "MyTestCls"
    ],
    "attributes": {
        "s": "ub",
        "dct": {
            "7": 7
        }
    }
}

If you like to make your own solution, you might look at the source of json-tricks so as not to forget some special cases (like __slots__).

It also does other types like numpy arrays, datetimes, complex numbers; it also allows for comments.

Nicely explained above!

For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the % with a !

So:

SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

You can use following ways to setup Spark:

• Building from Source
• Using prebuilt release

Though there are various ways to build Spark from Source.
First I tried building Spark source with SBT but that requires hadoop. To avoid those issues, I used pre-built release.

Instead of Source,I downloaded Prebuilt release for hadoop 2.x version and ran it. For this you need to install Scala as prerequisite.

I have collated all steps here :

Hope it'll help you..!!!

If you only need the first row from each group we can do with drop_duplicates, Notice the function default method keep='first'.

df.drop_duplicates('id')
Out[1027]: 
    id   value
0    1   first
3    2   first
5    3   first
9    4  second
11   5   first
12   6   first
15   7  fourth

You could try this registry hack:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"DeadGWDetectDefault"=dword:00000001
"KeepAliveTime"=dword:00120000

If it works, just keep increasing the KeepAliveTime. It is currently set for 2 minutes.

The simplest solution. in your application.properties file. add the following property as mentioned by a previous answer:

spring.main.web-environment=false

For version 2.0.0 of Spring boot starter, use the following property :

spring.main.web-application-type=none

For documentation on all properties use this link : https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

As a slight improvement over the other answers, you can do the mkdir and chmod as a single operation using mkdir's -m switch.

$ mkdir -m 700 ${HOME}/.ssh

Usage

From a Linux system

$ mkdir --help
Usage: mkdir [OPTION]... DIRECTORY...
Create the DIRECTORY(ies), if they do not already exist.

Mandatory arguments to long options are mandatory for short options too.
  -m, --mode=MODE   set file mode (as in chmod), not a=rwx - umask
...
...

something along this?

function dump(x, indent) {
    var indent = indent || '';
    var s = '';
    if (Array.isArray(x)) {
        s += '[';
        for (var i=0; i<x.length; i++) {
            s += dump(x[i], indent)
            if (i < x.length-1) s += ', ';
        }
        s +=']';
    } else if (x === null) {
      s = 'NULL';
    } else switch(typeof x) {
        case 'undefined':
            s += 'UNDEFINED';
            break;
        case 'object':
            s += "{ ";
            var first = true;
            for (var p in x) {
                if (!first) s += indent + '  ';
                s += p + ': ';
                s += dump(x[p], indent + '  ');
                s += "\n"
                first = false;
            }
            s += '}';
            break;
        case 'boolean':
            s += (x) ? 'TRUE' : 'FALSE';
            break;
        case 'number':
            s += x;
            break;
        case 'string':
            s += '"' + x + '"';
            break;
        case 'function':
            s += '<FUNCTION>';
            break;
        default:
            s += x;
            break;
    }
    return s;
}

The sizeof the structure should be 8 bytes on a 32 bit system, so that the size of the structure becomes multiple of 2. This makes individual structures available at the correct byte boundaries when an array of structures is declared. This is achieved by padding the structure with 3 bytes at the end.

If the structure had the pointer declared after the char, it would still be 8 bytes in size but the 3 byte padding would have been added to keep the pointer (which is a 4 byte element) aligned at a 4 byte address boundary.

The rule of thumb is that elements should be at an offset which is the multiple of their byte size and the structure itself should be of a size which is a multiple of 2.

Yeah a CSS primer will not hurt here so you can do two things: 1 - within the tags of your html you can open a style tag like this:

<style type="text/css">
  body {
   margin: 0px;
  }
  /*
   * this is the same as writing
   * body { margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;}
   * I'm adding px here for clarity sake but the unit is not really needed if you have 0
   * look into em, pt and % for other unit types 
   * the rules are always clockwise: top, right, bottom, left
  */
</style>

2- the above though will only work on the page you have this code embeded, so if if you wanted to reuse this in 10 files, then you will have to copy it over on all 10 files, and if you wanted to make a change let's say have a margin of 5px instead, you would have to open all those files and make the edit. That's why using an external style sheet is a golden rule in front end coding. So save the body declaration in a separate file named style.css for example and from your add this to your html instead:

<link rel="stylesheet" type="text/css" href="style.css"/>

Now you can put this in the of all pages that will benefit from these styles and whenever needed to change them you will only need to do so in one place. Hope it helps. Cheers

you can use multiple attribute

<SELECT NAME="Testing" multiple>  
 <OPTION VALUE="1"> One  
 <OPTION VALUE="2"> Two  
 <OPTION VALUE="3"> Three

If you can't find it in numpy or scipy, here are a couple of quick functions and a point class:

Strings are iterable (just like a list).

I'm interpreting that you really want something like:

fd = open(filename,'rU')
chars = []
for line in fd:
   for c in line:
       chars.append(c)

or

fd = open(filename, 'rU')
chars = []
for line in fd:
    chars.extend(line)

or

chars = []
with open(filename, 'rU') as fd:
    map(chars.extend, fd)

chars would contain all of the characters in the file.

I was having a problem where setting element.Visible = true in my code behind wasn't having any effect on the actual screen. The solution for me was to wrap the area of my page where I wanted to show the div in an ASP UpdatePanel, which is used to cause partial screen updates.

http://msdn.microsoft.com/en-us/library/bb399001.aspx

Having the element runat=server gave me access to it from the codebehind, and placing it in the UpdatePanel let it actually be updated on the screen.

If you can enable the CLR in SQL Server (requires 2005 or later) then you could create a CLR function that uses the TextInfo.ToTitleCase built-in function which would allow you to create a culture-aware way of doing this in only a few lines of code.

The & means that the function accepts the address (or reference) to a variable, instead of the value of the variable.

For example, note the difference between this:

void af(int& g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

And this (without the &):

void af(int g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

You can get if from your document_cache folder, subfolder (mine is 1946507). Once there, rename the "content" by adding .pdf to the end of the file, save, and open with any pdf reader.

@P-A's solution partially works for me. Detail my findings below:

1) The first code snippet is incorrect, see below:

<activity
    ...
    <intent-filter>
        ==> <action android:name="android.intent.action.MAIN" /> <== This line shouldn't be deleted, otherwise will have compile error
        <category android:name="android.intent.category.LAUNCHER" /> //DELETE THIS LINE
    </intent-filter>
</activity>

2) Should use following code to disable all icons before enabling another one, otherwise it will add a new icon, instead of replacing it.

getPackageManager().setComponentEnabledSetting(
        getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

BUT, if you use code above, then shortcut on homescreen will be removed! And it won't be automatically added back. You might be able to programmatically add icon back, but it probably won't stay in the same position as before.

3) Note that the icon won't get changed immediately, it might take several seconds. If you click it right after changing, you might get an error saying: "App isn't installed".

So, IMHO this solution is only suitable for changing icon in app launcher only, not for shortcuts (i.e. the icon on homescreen)

I found the actual solution...There is a problem in invoking your service from the client.. check the following things.

1. Make sure all [datacontract], [datamember] attribute are placed properly i.e. make sure WCF is error free

2. The WCF client, either web.config or any window app config, make sure config entries are properly pointing to the right ones.. binding info, url of the service..etc..etc

Then above problem : tempuri issue is resolved.. it has nothing to do with namespace.. though you are sure you lived with default,

Hope it saves your number of hours!

It seems that your

You can do this in a slight different way, like this

$('.btn').click(function(){
    // Send the src on click of button to the iframe. Which will make it load.

    $('.modal').modal({show:true});

Use Tkinter there are a ton of tutorials online for this. basically, you can create events. Here is a link to a great site! This makes it easy to capture clicks. Also, if you are trying to make a game, Tkinter also has a GUI. Although, I wouldn't recommend Python for games at all, it could be a fun experiment. Good Luck!

One option is strtok

example:

char name[20];
//pretend name is set to the value "My name"

You want to split it at the space between the two words

split=strtok(name," ");

while(split != NULL)
{
    word=split;
    split=strtok(NULL," ");
}

The standard principle is separate event handlers shouldn't depend upon the order they are called. If they do depend upon the order they should not be separate.

Otherwise, you register one event handler as being 'first' and someone else then registers their event handler as 'first' and you're back in the same mess as before.

def xor_strings(s1, s2):
    max_len = max(len(s1), len(s2))
    s1 += chr(0) * (max_len - len(s1))
    s2 += chr(0) * (max_len - len(s2))
    return ''.join([chr(ord(c1) ^ ord(c2)) for c1, c2 in zip(s1, s2)])

Your code was very close to working.

Try using a regular csv.writer rather than a DictWriter. The latter is mainly used for writing a list of dictionaries.

Here's some code that writes each key/value pair on a separate row:

import csv

somedict = dict(raymond='red', rachel='blue', matthew='green')
with open('mycsvfile.csv','wb') as f:
    w = csv.writer(f)
    w.writerows(somedict.items())

If instead you want all the keys on one row and all the values on the next, that is also easy:

with open('mycsvfile.csv','wb') as f:
    w = csv.writer(f)
    w.writerow(somedict.keys())
    w.writerow(somedict.values())

Pro tip: When developing code like this, set the writer to w = csv.writer(sys.stderr) so you can more easily see what is being generated. When the logic is perfected, switch back to w = csv.writer(f).

change your flag Windowmanger flag "TYPE_SYSTEM_OVERLAY" to "TYPE_APPLICATION_OVERLAY" in your project to make compatible with Android O

WindowManager.LayoutParams.TYPE_PHONE to WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY

Word of warning if using "smtp.gmail.com" as the default smtp server.

Google will force you to change your linked email account password frequently due to their over zealous "suspicious activity" polices. In essence it treats repeated smtp requests from different countries within a short time frame as "suspicious activity". As they assume you (the email account holder) can only be in one country at a time.

When google systems detect "suspicious activity" it will prevent further emails until you change the password. As you will have hard coded the password into the app you have to re-release the app each time this happens, not ideal. This happened 3 times in a week to me, I even stored the password on another server and dynamically fetched the password each time google forced me to change it.

So I recommend using one of the many free smtp providers instead of "smtp.gmail.com" to avoid this security problem. Use the same code but change "smtp.gmail.com" to your new smtp forwarding host.

I wanted to do exactly this, and I thought of a solution involving both the keyup and the keypress events.

(I haven't tested it in all browsers, but I used the information compiled at http://unixpapa.com/js/key.html)

Edit: rewrote it as a jQuery plugin.

(function($) {
    $.fn.normalkeypress = function(onNormal, onSpecial) {
        this.bind('keydown keypress keyup', (function() {
            var keyDown = {}, // keep track of which buttons have been pressed
                lastKeyDown;
            return function(event) {
                if (event.type == 'keydown') {
                    keyDown[lastKeyDown = event.keyCode] = false;
                    return;
                }
                if (event.type == 'keypress') {
                    keyDown[lastKeyDown] = event; // this keydown also triggered a keypress
                    return;
                }

                // 'keyup' event
                var keyPress = keyDown[event.keyCode];
                if ( keyPress &&
                     ( ( ( keyPress.which >= 32 // not a control character
                           //|| keyPress.which == 8  || // \b
                           //|| keyPress.which == 9  || // \t
                           //|| keyPress.which == 10 || // \n
                           //|| keyPress.which == 13    // \r
                           ) &&
                         !( keyPress.which >= 63232 && keyPress.which <= 63247 ) && // not special character in WebKit < 525
                         !( keyPress.which == 63273 )                            && //
                         !( keyPress.which >= 63275 && keyPress.which <= 63277 ) && //
                         !( keyPress.which === event.keyCode && // not End / Home / Insert / Delete (i.e. in Opera < 10.50)
                            ( keyPress.which == 35  || // End
                              keyPress.which == 36  || // Home
                              keyPress.which == 45  || // Insert
                              keyPress.which == 46  || // Delete
                              keyPress.which == 144    // Num Lock
                              )
                            )
                         ) ||
                       keyPress.which === undefined // normal character in IE < 9.0
                       ) &&
                     keyPress.charCode !== 0 // not special character in Konqueror 4.3
                     ) {

                    // Normal character
                    if (onNormal) onNormal.call(this, keyPress, event);
                } else {
                    // Special character
                    if (onSpecial) onSpecial.call(this, event);
                }
                delete keyDown[event.keyCode];
            };
        })());
    };
})(jQuery);

mail [-s subject] [-c ccaddress] [-b bccaddress] toaddress

-c and -b are optional.

-s : Specify subject;if subject contains spaces, use quotes.

-c : Send carbon copies to list of users seperated by comma.

-b : Send blind carbon copies to list of users seperated by comma.

Hope my answer clarifies your doubt.

Try this, it will worked. I used it for Hashtable.

public static Hashtable<Integer, KioskStatusResource> parseModifued(String json) {
    JsonObject object = (JsonObject) new com.google.gson.JsonParser().parse(json);
    Set<Map.Entry<String, JsonElement>> set = object.entrySet();
    Iterator<Map.Entry<String, JsonElement>> iterator = set.iterator();

    Hashtable<Integer, KioskStatusResource> map = new Hashtable<Integer, KioskStatusResource>();

    while (iterator.hasNext()) {
        Map.Entry<String, JsonElement> entry = iterator.next();

        Integer key = Integer.parseInt(entry.getKey());
        KioskStatusResource value = new Gson().fromJson(entry.getValue(), KioskStatusResource.class);

        if (value != null) {
            map.put(key, value);
        }

    }
    return map;
}

Replace KioskStatusResource to your class and Integer to your key class.

You can do it without dealing with encoding by using BlockCopy:

char[] chars = new char[bytes.Length / sizeof(char)];
System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
string str = new string(chars);

Try something like this:

div {
    background-image: url(../img/picture1.jpg);
    height: 30em;
    background-repeat: no-repeat;
    width: 100%;
    background-position: center;
}

Use JQuery Hover to add/remove class or style on Hover:

$( "mah div" ).hover(
  function() {
    $( this ).css("background-color","red");
  }, function() {
    $( this ).css("background-color",""); //to remove property set it to ''
  }
);

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." />

Replace it by:

<context:component-scan base-package="org.assessme.com." />

It is because your Autowired service is not scanned by Spring since it is not in the right package.

You are trying to copy a string into an address that is statically allocated. You need to cat into a buffer.

Specifically:

...snip...

destination

Pointer to the destination array, which should contain a C string, and be large enough to contain the concatenated resulting string.

...snip...

http://www.cplusplus.com/reference/clibrary/cstring/strcat.html

There's an example here as well.

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);

Seconds with 2 decimal spaces:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime) / 1000000, "#,##0.00") & " seconds") 'end timer

Milliseconds:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime), "#,##0.00") & " milliseconds") 'end timer

Milliseconds with comma seperator:

Dim startTime As Single 'start timer
MsgBox ("run time: " & Format((Timer - startTime) * 1000, "#,##0.00") & " milliseconds") 'end timer

Just leaving this here for anyone that was looking for a simple timer formatted with seconds to 2 decimal spaces like I was. These are short and sweet little timers I like to use. They only take up one line of code at the beginning of the sub or function and one line of code again at the end. These aren't meant to be crazy accurate, I generally don't care about anything less then 1/100th of a second personally, but the milliseconds timer will give you the most accurate run time of these 3. I've also read you can get the incorrect read out if it happens to run while crossing over midnight, a rare instance but just FYI.

The above answer didn't work with Angular 6. So following is how I resolved it. Lets say this is how I defined my input box -

<input type="number" id="myTextBox" name="myTextBox"_x000D_
 [(ngModel)]="response.myTextBox"_x000D_
            #myTextBox="ngModel">

To check if the field is empty or not this should be the script.

<div *ngIf="!myTextBox.value" style="color:red;">_x000D_
 Your field is empty_x000D_
</div>

Do note the subtle difference between the above answer and this answer. I have added an additional attribute .value after my input name myTextBox. I don't know if the above answer worked for above version of Angular, but for Angular 6 this is how it should be done.

Some more explanation on why this check works; when there is no value present in the input box the default value of myTextBox.value will be undefined. As soon as you enter some text, your text becomes the new value of myTextBox.value.

When your check is !myTextBox.value it is checking that the value is undefined or not, it is equivalent to myTextBox.value == undefined.

I was recently dealing with an issue when I was trying to get past authentication while making a REST call from Java, and while the answers in this thread (and other threads) helped, there was still a bit of trial and error involved in getting it working.

What worked for me was encoding credentials in Base64 and adding them as Basic Authorization headers. I then added them as an HttpEntity to restTemplate.postForEntity, which gave me the response I needed.

Here's the class I wrote for this in full (extending RestTemplate):

public class AuthorizedRestTemplate extends RestTemplate{

    private String username;
    private String password;

    public AuthorizedRestTemplate(String username, String password){
        this.username = username;
        this.password = password;
    }

    public String getForObject(String url, Object... urlVariables){
        return authorizedRestCall(this, url, urlVariables);
    }

    private String authorizedRestCall(RestTemplate restTemplate, 
            String url, Object... urlVariables){
        HttpEntity<String> request = getRequest();
        ResponseEntity<String> entity = restTemplate.postForEntity(url, 
                request, String.class, urlVariables);
        return entity.getBody();
    }

    private HttpEntity<String> getRequest(){
        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + getBase64Credentials());
        return new HttpEntity<String>(headers);
    }

    private String getBase64Credentials(){
        String plainCreds = username + ":" + password;
        byte[] plainCredsBytes = plainCreds.getBytes();
        byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
        return new String(base64CredsBytes);
    }
}

Use specific value:

[Display(Name = "Date")]
public DateTime EntryDate {get; set;} = DateTime.Now;//by C# v6

if byte1 is an 8-bit integer type then it's pointless - if it is more than 8 bits it will essentially give you the last 8 bits of the value:

    0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1
 &  0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1
    -------------------------------
    0 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1

You can set min-width property of CSS for body tag. Since this property is not supported by IE6, you can write like:

body{
   min-width:1000px;        /* Suppose you want minimum width of 1000px */
   width: auto !important;  /* Firefox will set width as auto */
   width:1000px;            /* As IE6 ignores !important it will set width as 1000px; */
}

Or:

body{
   min-width:1000px; // Suppose you want minimum width of 1000px
   _width: expression( document.body.clientWidth > 1000 ? "1000px" : "auto" ); /* sets max-width for IE6 */
}

There's an excellent module for flow control in node.js called asyncblock. If wrapping the code in a function is OK for your case, the following sample may be considered:

var asyncblock = require('asyncblock');
var exec = require('child_process').exec;

asyncblock(function (flow) {
    exec('node -v', flow.add());
    result = flow.wait();
    console.log(result);    // There'll be trailing \n in the output

    // Some other jobs
    console.log('More results like if it were sync...');
});

Checking your linked site, you may include a script tag passing a ?var=desiredVarName parameter which will be set as a global variable containing the IP address:

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
                                                      <!-- ^^^^ -->
<script>alert(myip);</script>

Demo

I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.

HTTPS support

In case your page is served using the https protocol, most browsers will block content in the same page served using the http protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:

<script>
var myip;
function ip_callback(o) {
    myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>

Demo

Edit: Apparently, this https service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json

With back-end logic

The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script> tag, this way you don't need to rely on external resources. For example:

PHP:

<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>

There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.

C#:

<script>var myip = '<%= Request.UserHostAddress %>';</script>

What worked for me is that i hadn't set the local_listener, to see if the local listener is set login to sqlplus / as sysdba, make sure the database is open and run the following command show parameter local_listener, if the value is empty, then you will have to set the local_listener with the following SQL command ALTER SYSTEM SET LOCAL_LISTENER='<LISTENER_NAME_GOES_HERE>'

A static library must be linked into the final executable; it becomes part of the executable and follows it wherever it goes. A dynamic library is loaded every time the executable is executed and remains separate from the executable as a DLL file.

You would use a DLL when you want to be able to change the functionality provided by the library without having to re-link the executable (just replace the DLL file, without having to replace the executable file).

You would use a static library whenever you don't have a reason to use a dynamic library.

you can simply write:

for item,i in zip(your_list, range(len(your_list)):

    if type(item) == list:
        print(f"{item} at index {i} is a list")

An array isn't immutable by nature; you can't make it constant.

The nearest you can get is:

var letter_goodness = [...]float32 {.0817, .0149, .0278, .0425, .1270, .0223, .0202, .0609, .0697, .0015, .0077, .0402, .0241, .0675, .0751, .0193, .0009, .0599, .0633, .0906, .0276, .0098, .0236, .0015, .0197, .0007 }

Note the [...] instead of []: it ensures you get a (fixed size) array instead of a slice. So the values aren't fixed but the size is.

A node is the base class for both elements and attributes (and basically all other XML representations too).

Your solution is ok. only try it in this way:

files=$(grep -rl oldstr path) && echo $files | xargs sed....

so execute the xargs only when grep return 0, e.g. when found the string in some files.

An other example would be on the "created_on" column where you want to let the database handle the date creation

In case you are on Mac, ensure that you exit Docker for Mac. This worked for me.

As others have said, you should do both. Here's why:

Client Side

You want to validate input on the client side first because you can give better feedback to the average user. For example, if they enter an invalid email address and move to the next field, you can show an error message immediately. That way the user can correct every field before they submit the form.

If you only validate on the server, they have to submit the form, get an error message, and try to hunt down the problem.

(This pain can be eased by having the server re-render the form with the user's original input filled in, but client-side validation is still faster.)

Server Side

You want to validate on the server side because you can protect against the malicious user, who can easily bypass your JavaScript and submit dangerous input to the server.

It is very dangerous to trust your UI. Not only can they abuse your UI, but they may not be using your UI at all, or even a browser. What if the user manually edits the URL, or runs their own Javascript, or tweaks their HTTP requests with another tool? What if they send custom HTTP requests from curl or from a script, for example?

(This is not theoretical; eg, I worked on a travel search engine that re-submitted the user's search to many partner airlines, bus companies, etc, by sending POST requests as if the user had filled each company's search form, then gathered and sorted all the results. Those companies' form JS was never executed, and it was crucial for us that they provide error messages in the returned HTML. Of course, an API would have been nice, but this was what we had to do.)

Not allowing for that is not only naive from a security standpoint, but also non-standard: a client should be allowed to send HTTP by whatever means they wish, and you should respond correctly. That includes validation.

Server side validation is also important for compatibility - not all users, even if they're using a browser, will have JavaScript enabled.

Addendum - December 2016

There are some validations that can't even be properly done in server-side application code, and are utterly impossible in client-side code, because they depend on the current state of the database. For example, "nobody else has registered that username", or "the blog post you're commenting on still exists", or "no existing reservation overlaps the dates you requested", or "your account balance still has enough to cover that purchase." Only the database can reliably validate data which depends on related data. Developers regularly screw this up, but PostgreSQL provides some good solutions.

Your code actually works on FF, it doesn't work on Chrome.

This works on FF and Chrome.

$(document).ready(function() {
        // Solution for disabling the submit temporarily for all the submit buttons.
        // Avoids double form submit.
        // Doing it directly on the submit click made the form not to submit in Chrome.
        // This works in FF and Chrome.
        $('form').on('submit', function(e){
          //console.log('submit2', e, $(this).find('[clicked=true]'));
          var submit = $(this).find('[clicked=true]')[0];
          if (!submit.hasAttribute('disabled'))
          {
            submit.setAttribute('disabled', true);
            setTimeout(function(){
              submit.removeAttribute('disabled');
            }, 1000);
          }
          submit.removeAttribute('clicked');
          e.preventDefault();
        });
        $('[type=submit]').on('click touchstart', function(){
          this.setAttribute('clicked', true);
        });
      });
    </script>

You can just implement the Map.Entry<K, V> interface yourself:

import java.util.Map;

final class MyEntry<K, V> implements Map.Entry<K, V> {
    private final K key;
    private V value;

    public MyEntry(K key, V value) {
        this.key = key;
        this.value = value;
    }

    @Override
    public K getKey() {
        return key;
    }

    @Override
    public V getValue() {
        return value;
    }

    @Override
    public V setValue(V value) {
        V old = this.value;
        this.value = value;
        return old;
    }
}

And then use it:

Map.Entry<String, Object> entry = new MyEntry<String, Object>("Hello", 123);
System.out.println(entry.getKey());
System.out.println(entry.getValue());

There is no Pair in the standard framework, but the Apache Commons Lang, which comes quite close to “standard”, has a Pair.

My experience with Django is minimal but I do remember in The Django Book they have a chapter where they interview people running some of the larger Django applications. Here is a link. I guess it could provide some insights.

It says curse.com is one of the largest Django applications with around 60-90 million page views in a month.

In my opinion the application tier should have no business determining where data should be stored

This is a good rule but like most things not always correct.

When you do your architecture you start with responsibilities and collaborations. Once you determine your functional architecture, you have to balance the non-functional forces.

If one of these non-functional forces is massive scalability, you have to adapt your architecture to cater for this force even if it means that your data storage abstraction now leaks into your application tier.

The definition of method_two is invalid. When you call method_two, you'll get TypeError: method_two() takes 0 positional arguments but 1 was given from the interpreter.

An instance method is a bounded function when you call it like a_test.method_two(). It automatically accepts self, which points to an instance of Test, as its first parameter. Through the self parameter, an instance method can freely access attributes and modify them on the same object.

Use compareTo()

Return Values

0 if the argument Date is equal to this Date; a value less than 0 if this Date is before the Date argument; and a value greater than 0 if this Date is after the Date argument.

Like

if(date1.compareTo(date2)>0) 

On top of your lastest jsfiddle, you just missed one thing:

#sidebar_wrap {
  width:40%;
  height:200px;
  background:green;
  float:right;
}
#sidebar {
  width:inherit;
  margin-top:10px;
  background-color:limegreen;
  position:fixed;
  max-width: 240px; /*This is you missed*/
}

But, how this will solve your problem? Simple, lets explain why is bigger than expect first.

Fixed element #sidebar will use window width size as base to get its own size, like every other fixed element, once in this element is defined width:inherit and #sidebar_wrap has 40% as value in width, then will calculate window.width * 40%, then when if your window width is bigger than your .container width, #sidebar will be bigger than #sidebar_wrap.

This is way, you must set a max-width in your #sidebar_wrap, to prevent to be bigger than #sidebar_wrap.

Check this jsfiddle that shows a working code and explain better how this works.

You can also do it this way without the need of Linq:

List<int> numbers = new List<int>( Array.ConvertAll(sNumbers.Split(','), int.Parse) );

// Uses Linq
var numbers = Array.ConvertAll(sNumbers.Split(','), int.Parse).ToList();

Some of the following was gleaned off of this site. This is what I did to duplicate a record in a table with any number of fields:

This also assumes you have an AI field at the beginning of the table

function duplicateRow( $id = 1 ){
dbLink();//my db connection
$qColumnNames = mysql_query("SHOW COLUMNS FROM table") or die("mysql error");
$numColumns = mysql_num_rows($qColumnNames);

for ($x = 0;$x < $numColumns;$x++){
$colname[] = mysql_fetch_row($qColumnNames);
}

$sql = "SELECT * FROM table WHERE tableId = '$id'";
$row = mysql_fetch_row(mysql_query($sql));
$sql = "INSERT INTO table SET ";
for($i=1;$i<count($colname)-4;$i++){//i set to 1 to preclude the id field
//we set count($colname)-4 to avoid the last 4 fields (good for our implementation)
$sql .= "`".$colname[$i][0]."`  =  '".$row[$i]. "', ";
}
$sql .= " CreateTime = NOW()";// we need the new record to have a new timestamp
mysql_query($sql);
$sql = "SELECT MAX(tableId) FROM table";
$res = mysql_query($sql);
$row = mysql_fetch_row($res);
return $row[0];//gives the new ID from auto incrementing
}

I was facing the same problem today and made up a wrapper class, which checks before every method if the element reference is still valid. My solution to retrive the element is pretty simple so i thought i'd just share it.

private void setElementLocator()
{
    this.locatorVariable = "selenium_" + DateTimeMethods.GetTime().ToString();
    ((IJavaScriptExecutor)this.driver).ExecuteScript(locatorVariable + " = arguments[0];", this.element);
}

private void RetrieveElement()
{
    this.element = (IWebElement)((IJavaScriptExecutor)this.driver).ExecuteScript("return " + locatorVariable);
}

You see i "locate" or rather save the element in a global js variable and retrieve the element if needed. If the page gets reloaded this reference will not work anymore. But as long as only changes are made to doom the reference stays. And that should do the job in most cases.

Also it avoids re-searching the element.

Android Studio is based on IntelliJ, and it comes with support for SVN (along with git and mercurial) bundled in. Check http://www.jetbrains.com/idea/features/version_control.html for more info.

#if defined(__OBJC__)
    #define __bool BOOL
    #include <stdbool.h>
    #define __bool bool
#endif

static inline __bool xor(__bool a, __bool b)
{
    return (!a && b) || (a && !b);
}

It works as defined. The conditionals are to detect if you are using Objective-C, which is asking for BOOL instead of bool (the length is different!)

There is always sys.exit().

The system library in Python's core library has an exit function which is super handy when prototyping. The code would be along the lines of:

import sys

while True:
    selection = raw_input("U: Create User\nQ: Quit")
    if selection is "Q" or selection is "q":
        print("Quitting")
        sys.exit()
    if selection is "U" or selection is "u":
        print("User")
        #do_something()

I collected 2200 bad words in 12 languages: en, ar, cs, da, de, eo, es, fa, fi, fr, hi, hu, it, ja, ko, nl, no, pl, pt, ru, sv, th, tlh, tr, zh.

MySQL dump, JSON, XML or CSV options are available.

https://github.com/turalus/openDB

I'd suggest you to execute this SQL into your DB and check everytime when user inputs something.

def get_code(str)
  str.sub(/^(Z_.*): .*/, '\1')
end
get_code('Z_foo: bar!') # => "Z_foo"

This is also an interesting way:

def reverse_words_1(s):
    rev = ''
    for i in range(len(s)):
        j = ~i  # equivalent to j = -(i + 1)
        rev += s[j]
    return rev

or similar:

def reverse_words_2(s):
    rev = ''
    for i in reversed(range(len(s)):
        rev += s[i]
    return rev

Another more 'exotic' way using byterarray which supports .reverse()

b = bytearray('Reverse this!', 'UTF-8')
b.reverse()
b.decode('UTF-8')

will produce:

'!siht esreveR'

To take it a step further, you can place globally used constants in an interface so they can be used system wide. E.g.

public interface MyGlobalConstants {
    public static final int TIMEOUT_IN_SECS = 25;
}

But don't then implement it. Just refer to them directly in code via the fully qualified classname.

For repeating an action in the future, there is the built in setInterval function that you can use instead of setTimeout.
It has a similar signature, so the transition from one to another is simple:

setInterval(function() {
    // do stuff
}, duration);

A simple extension method for this would be:

    public static void AddParameter(this SqlCommand sqlCommand, string parameterName, 
        SqlDbType sqlDbType, object item)
    {
        sqlCommand.Parameters.Add(parameterName, sqlDbType).Value = item ?? DBNull.Value;
    }

Your question will trigger discussion I suppose. The general idea is that it's good to separate behavior and structure. Furthermore, afaik, an inline click handler has to be evalled to 'become' a real javascript function. And it's pretty old fashioned, allbeit that that's a pretty shaky argument. Ah, well, read some about it @quirksmode.org

If these are just going to be textblocks (and thus one way binding), and you just want to concatenate values, just bind two textblocks and put them in a horizontal stackpanel.

    <StackPanel Orientation="Horizontal">
        <TextBlock Text="{Binding Name}"/>
        <TextBlock Text="{Binding ID}"/>
    </StackPanel>

That will display the text (which is all Textblocks do) without having to do any more coding. You might put a small margin on them to make them look right though.

Alternate solution. I prefer this for the brevity and code simplicity.

(function () {
    alert("I am here");
})();

This is an anonymous function, where the name is not specified. What happens here is that, the function is defined and executed together. Add this to the beginning or end of the body, depending on if it is to be executed before loading the page or soon after all the HTML elements are loaded.

If your server is not resolving the file from the parent directory using

include '../somefilein_parent.php'

try this (using the parent directory relative to the script):

include __DIR__ . "/../somefilein_parent.php";

Because gets doesn't do any kind of check while getting bytes from stdin and putting them somewhere. A simple example:

char array1[] = "12345";
char array2[] = "67890";

gets(array1);

Now, first of all you are allowed to input how many characters you want, gets won't care about it. Secondly the bytes over the size of the array in which you put them (in this case array1) will overwrite whatever they find in memory because gets will write them. In the previous example this means that if you input "abcdefghijklmnopqrts" maybe, unpredictably, it will overwrite also array2 or whatever.

The function is unsafe because it assumes consistent input. NEVER USE IT!

ocw.mit.edu is a great resource that has helped me a bunch. randi is the best option, but if your into number fun try using the floor function with rand to get what you want.

I drew a number line and came up with

floor(rand*8) + 13

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

if you want to copy folder from currant directory to binary (build folder) folder

file(COPY ${CMAKE_CURRENT_SOURCE_DIR}/yourFolder/ DESTINATION ${CMAKE_CURRENT_BINARY_DIR}/yourFolder/)

then the syntexe is :

file(COPY pathSource DESTINATION pathDistination)

@Query("SELECT distinct new com.model.referential.Asset(firefCode,firefDescription) FROM AssetClass ")
List<AssetClass> findDistinctAsset();

This is how did it works like a charm.

CSS

#loader {
position:fixed;
left:1px;
top:1px;
width: 100%;
height: 100%;
z-index: 9999;

background: url('../images/ajax-loader100X100.gif') 50% 50% no-repeat rgb(249,249,249);
}  

in _layout file inside body tag but outside the container div. Every time page loads it shows loading. Once page is loaded JS fadeout(second)

<div id="loader">
</div>

JS at the bottom of _layout file

<script type="text/javascript">
// With the element initially shown, we can hide it slowly:
 $("#loader").fadeOut(1000);
</script>  

This is what I ended up doing:

<div style="height: 600px">
   <img src="assets/zzzzz.png" alt="Error" style="max-width: 100%; 
        max-height: 100%; display:block; margin:auto;" />
</div>

Which will limit the image height to 600px and will horizontally-center (or resize down if the parent width is smaller) to the parent container, maintaining proportions.

Run apt-get install build-essential on your system.

This package depends on other packages considered to be essential for builds and will install them. If you find you have to build packages, this can be helpful to avoid piecemeal resolution of dependencies.

You need to apply DATE_FORMAT in the SELECT clause, not the WHERE clause:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

Also note that CURDATE() returns only the DATE portion of the date, so if you store create_date as a DATETIME with the time portion filled, this query will not select the today's records.

In this case, you'll need to use NOW instead:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()

The JPA 2.0 Specification states that:

• The entity class must have a no-arg constructor. It may have other constructors as well. The no-arg constructor must be public or protected.
• The entity class must a be top-level class. An enum or interface must not be designated as an entity.
• The entity class must not be final. No methods or persistent instance variables of the entity class may be final.
• If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the entity class must implement the Serializable interface.
• Both abstract and concrete classes can be entities. Entities may extend non-entity classes as well as entity classes, and non-entity classes may extend entity classes.

The specification contains no requirements about the implementation of equals and hashCode methods for entities, only for primary key classes and map keys as far as I know.

In iOS8 sizeWithFont has been deprecated, please refer to

CGSize yourLabelSize = [yourLabel.text sizeWithAttributes:@{NSFontAttributeName : [UIFont fontWithName:yourLabel.font size:yourLabel.fontSize]}];

You can add all the attributes you want in sizeWithAttributes. Other attributes you can set:

- NSForegroundColorAttributeName
- NSParagraphStyleAttributeName
- NSBackgroundColorAttributeName
- NSShadowAttributeName

and so on. But probably you won't need the others

if key in array:
  # do something

Associative arrays are called dictionaries in Python and you can learn more about them in the stdtypes documentation.

A more general solution could be a extension

extension String {
    var toFloat:Float {
        return Float(self.bridgeToObjectiveC().floatValue)
    }
    var toDouble:Double {
        ....
    }
    ....
}

this for example extends the swift native String object by toFloat

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

Dividing the app into blueprints is a great idea. However, if this isn't enough, and if you want to then divide the Blueprint itself into multiple py files, this is also possible using the regular Python module import system, and then looping through all the routes that get imported from the other files.

I created a Gist with the code for doing this:

https://gist.github.com/Jaza/61f879f577bc9d06029e

As far as I'm aware, this is the only feasible way to divide up a Blueprint at the moment. It's not possible to create "sub-blueprints" in Flask, although there's an issue open with a lot of discussion about this:

https://github.com/mitsuhiko/flask/issues/593

Also, even if it were possible (and it's probably do-able using some of the snippets from that issue thread), sub-blueprints may be too restrictive for your use case anyway - e.g. if you don't want all the routes in a sub-module to have the same URL sub-prefix.

As previously mentioned it is officially not possible to change the format. However it is possible to style the field, so (with a little JS help) it displays the date in a format we desire. Some of the possibilities to manipulate the date input is lost this way, but if the desire to force the format is greater, this solution might be a way. A date fields stays only like that:

<input type="date" data-date="" data-date-format="DD MMMM YYYY" value="2015-08-09">

The rest is a bit of CSS and JS: http://jsfiddle.net/g7mvaosL/

$("input").on("change", function() {_x000D_
    this.setAttribute(_x000D_
        "data-date",_x000D_

    )_x000D_
}).trigger("change")

It works nicely on Chrome for desktop, and Safari on iOS (especially desirable, since native date manipulators on touch screens are unbeatable IMHO). Didn't check for others, but don't expect to fail on any Webkit.

There are two ways-

or

echo $USER

yourTextView.setText(String.format("Value of a: %.2f", a));

    while(i<10){
               $('#Postsoutput').prepend('<div id="first'+i+'">'+i+'</div>');
               /* get the dynamic Div*/
               $('#first'+i).hide(1000);
               $('#first'+i).show(1000);
                i++;
                }

I had the same problem... I am a complete beginner In my case it happened cause I was trying to do: git merge random_branch/file.txt My problem was solved when I retired the file.txt and let just the branch name (lol) kkfdskfskdfs

git merge random_branch worked pretty well

Ruby's just the same, btw, offering both #length and #size as synonyms for the number of items in arrays and hashes (C++ only does it for strings).

Minimalists and people who believe "there ought to be one, and ideally only one, obvious way to do it" (as the Zen of Python recites) will, I guess, mostly agree with your doubts, @Naveen, while fans of Perl's "There's more than one way to do it" (or SQL's syntax with a bazillion optional "noise words" giving umpteen identically equivalent syntactic forms to express one concept) will no doubt be complaining that Ruby, and especially C++, just don't go far enough in offering such synonymical redundancy;-).

var arr = _.map(obj)

You can use _.map function (of both lodash and underscore) with object as well, it will internally handle that case, iterate over each value and key with your iteratee, and finally return an array. Infact, you can use it without any iteratee (just _.map(obj)) if you just want a array of values. The good part is that, if you need any transformation in between, you can do it in one go.

Example:

var obj = {_x000D_
    key1: {id: 1, name: 'A'},_x000D_
    key2: {id: 2, name: 'B'},_x000D_
    key3: {id: 3, name: 'C'}_x000D_
};_x000D_
_x000D_
var array1 = _.map(obj, v=>v);_x000D_
console.log('Array 1: ', array1);_x000D_
_x000D_
/*Actually you don't need the callback v=>v if you_x000D_
are not transforming anything in between, v=>v is default*/_x000D_
_x000D_
//SO simply you can use_x000D_
var array2 = _.map(obj);_x000D_
console.log('Array 2: ', array2);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.js"></script>

However, if you want to transform your object you can do so, even if you need to preserve the key, you can do that ( _.map(obj, (v, k) => {...}) with additional argument in map and then use it how you want.

However there are other Vanilla JS solution to this (as every lodash solution there should pure JS version of it) like:

• Object.keys and then map them to values
• Object.values (in ES-2017)
• Object.entries and then map each key/value pairs (in ES-2017)
• for...in loop and use each keys for feting values

And a lot more. But since this question is for lodash (and assuming someone already using it) then you don't need to think a lot about version, support of methods and error handling if those are not found.

There are other lodash solutions like _.values (more readable for specific perpose), or getting pairs and then map and so on. but in the case your code need flexibility that you can update it in future as you need to preserve keys or transforming values a bit, then the best solution is to use a single _.map as addresed in this answer. That will bt not that difficult as per readability also.

I ran into the same issue and couldn't decide between laughing or smashing my head on the table when I read this error...

What git really tries to tell you: "You are already in a merge state and need to resolve the conflicts there first!"

You tried a merge and a conflict occured. Then, git stays in the merge state and if you want to resolve the merge with other commands git thinks you want to execute a new merge and so it tells you you can't do this because of your current unmerged files...

You can leave this state with git merge --abort and now try to execute other commands.

In my case I tried a pull and wanted to resolve the conflicts by hand when the error occured...

Yes, that is fine. $_POST is just another variable, except it has (super)global scope.

$_POST = array();

...will be quite enough. The loop is useless. It's probably best to keep it as an array rather than unset it, in case other files are attempting to read it and assuming it is an array.

In order to read a csv in that doesn't have a header and for only certain columns you need to pass params header=None and usecols=[3,6] for the 4th and 7th columns:

df = pd.read_csv(file_path, header=None, usecols=[3,6])

See the docs

Just to help those in a similar situation to myself...

This can be caused when a dependent library has accidentally bundled an old version of slf4j. In my case, it was tika-0.8. See https://issues.apache.org/jira/browse/TIKA-556

The workaround is exclude the component and then manually depends on the correct, or patched version.

EG.

<dependency>
    <groupId>org.apache.tika</groupId>
    <artifactId>tika-parsers</artifactId>
    <version>0.8</version>
    <exclusions>
        <exclusion>

            <artifactId>netcdf</artifactId>
        </exclusion>

• 401 (Unauthorized) response header -> Request authentication header

• Here are several WWW-Authenticate response headers. (The full list is at IANA: HTTP Authentication Schemes.)

  • WWW-Authenticate: Basic-> Authorization: Basic + token - Use for basic authentication
  • WWW-Authenticate: NTLM-> Authorization: NTLM + token (2 challenges)
  • WWW-Authenticate: Negotiate -> Authorization: Negotiate + token - used for Kerberos authentication
    • By the way: IANA has this angry remark about Negotiate: This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).

You can set the Authorization: Basic header only when you also have the WWW-Authenticate: Basic header on your 401 challenge.

But since you have WWW-Authenticate: Negotiate this should be the case for Kerberos based authentication.

PS C:> Set-ExecutionPolicy RemoteSigned Below is the list of four different execution policies in PowerShell

Restricted – No scripts can be run. AllSigned – Only scripts signed by a trusted publisher can be run. RemoteSigned – Downloaded scripts must be signed by a trusted publisher. Unrestricted – All Windows PowerShell scripts can be run.

For PHP 8+ we can omit the variable name for a caught exception.

catch

As of PHP 8.0.0, the variable name for a caught exception is optional. If not specified, the catch block will still execute but will not have access to the thrown object.

And thus we can do it like this:

try {
  throw new Exception("An error");
}
catch (Exception) {}

I think there's no reason not to use null for an unassigned (or at this place in a program flow not occurring) value. If you want to distinguish, there's ==null. If you just want to check for a certain value and don't care whether it's null or something different, String.Equals("XXX",MyStringVar) does just fine.

You can create these easily using the floating ability of CSS, for example. I have created a small example on Jsfiddle over here, all the related css and html is also provided there.

.foo {_x000D_
  float: left;_x000D_
  width: 20px;_x000D_
  height: 20px;_x000D_
  margin: 5px;_x000D_
  border: 1px solid rgba(0, 0, 0, .2);_x000D_
}_x000D_
_x000D_
.blue {_x000D_
  background: #13b4ff;_x000D_
}_x000D_
_x000D_
.purple {_x000D_
  background: #ab3fdd;_x000D_
}_x000D_
_x000D_
.wine {_x000D_
  background: #ae163e;_x000D_
}

<div class="foo blue"></div>_x000D_
<div class="foo purple"></div>_x000D_
<div class="foo wine"></div>

Try either multi-table update syntax

UPDATE config t1 JOIN config t2
    ON t1.config_name = 'name1' AND t2.config_name = 'name2'
   SET t1.config_value = 'value',
       t2.config_value = 'value2';

Here is SQLFiddle demo

or conditional update

UPDATE config
   SET config_value = CASE config_name 
                      WHEN 'name1' THEN 'value' 
                      WHEN 'name2' THEN 'value2' 
                      ELSE config_value
                      END
 WHERE config_name IN('name1', 'name2');

Here is SQLFiddle demo

After testing many options I've found that the following simple solution is loading the dynamically loaded scripts in the order in which they are added in all modern browsers

loadScripts(sources) {
    sources.forEach(src => {
        var script = document.createElement('script');
        script.src = src;
        script.async = false; //<-- the important part
        document.body.appendChild( script ); //<-- make sure to append to body instead of head 
    });
}

loadScripts(['/scr/script1.js','src/script2.js'])

You need to create toast on UI thread. Find the example below.

runOnUiThread(new Runnable() {
  public void run() {
    Toast.makeText(activity, "YOUR_MESSAGE", Toast.LENGTH_SHORT).show();
  }
});

For displaying Toast message please refer to this article

For Swift:

button.layer.cornerRadius = 10.0
