It's quite unclear how you are computing the size ("the size in debug mode"?").

Use printf():

printf("the size of c is %u\n", (unsigned int) sizeof c);

Normally you'd print a size_t value (which is the type sizeof returns) with %zu, but if you're using a pre-C99 compiler like Visual Studio that won't work.

You need to find the typedef statements in your code that define the custom names like uint8 and so on; those are not standard so nobody here can know how they're defined in your code.

New C code should use <stdint.h> which gives you uint8_t and so on.

I found a solution wich is to do:

<span class="visible-sm"> your code without col </span>
<span class="visible-xs"> your code with col </span>

It's not very optimized but it works. Did you find something better? It really miss a class like col-sm-0 to apply colons just to the xs size...

One option is to type [command] + [shift] + [p] (or the equivalent) and then type 'indentation'. The top result should be 'Indendtation: Reindent Lines'. Press [enter] and it will format the document.

Another option is to install the Emmet plugin (http://emmet.io/), which will provide not only better formatting, but also a myriad of other incredible features. To get the output you're looking for using Sublime Text 3 with the Emmet plugin requires just the following:

p [tab][enter] Hello world!

When you type p [tab] Emmet expands it to:

<p></p>

Pressing [enter] then further expands it to:

<p>

</p>

With the cursor indented and on the line between the tags. Meaning that typing text results in:

<p>
    Hello, world!
</p>

Add atribute in xml:

<android.support.design.widget.TabLayout
    ....
    app:tabBackground="@drawable/tab_color_selector"
    ...
    />

And create in drawable folder, tab_color_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/tab_background_selected" android:state_selected="true"/>
    <item android:drawable="@color/tab_background_unselected"/>
</selector>

Use the progress library!

pip install progress

Here is a custom subclass I wrote to format the ETA/Elapsed times into a better readable format:

import datetime
from progress.bar import IncrementalBar


class ProgressBar(IncrementalBar):
    '''
    My custom progress bar that:
       - Show %, count, elapsed, eta
       - Time is shown in H:M:S format
    '''

    message = 'Progress'
    suffix  = '%(percent).1f%% (%(index)d/%(max)d) -- %(elapsed_min)s (eta: %(eta_min)s)'

    def formatTime(self, seconds):
        return str(datetime.timedelta(seconds=seconds))

    @property
    def elapsed_min(self):
        return self.formatTime(self.elapsed)

    @property
    def eta_min(self):
        return self.formatTime(self.eta)

if __name__=='__main__':
    counter = 120
    bar     = ProgressBar('Processing', max=counter)

    for i in range(counter):
        bar.next()
        time.sleep(1)

    bar.finish()

In case you do not want to use Asset Catalog, you can add an iOS 7 icon for an old app by creating a 120x120 .png image. Name it Icon-120.png and drag in to the project.

Under TARGET > Your App > Info > Icon files, add one more entry in the Target Properties:

I tested on Xcode 5 and an app was submitted without the missing retina icon warning.

In my opinion, the accepted answer is confusing, since it uses a DataFrame with only missing values. I also do not like the term position-based for .iloc and instead, prefer integer location as it is much more descriptive and exactly what .iloc stands for. The key word is INTEGER - .iloc needs INTEGERS.

See my extremely detailed blog series on subset selection for more

.ix is deprecated and ambiguous and should never be used

Because .ix is deprecated we will only focus on the differences between .loc and .iloc.

Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each index. Let's take a look at a sample DataFrame:

df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
                   'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
                   'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
                   'height':[165, 70, 120, 80, 180, 172, 150],
                   'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
                   'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
                   },
                  index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])

All the words in bold are the labels. The labels, age, color, food, height, score and state are used for the columns. The other labels, Jane, Nick, Aaron, Penelope, Dean, Christina, Cornelia are used for the index.

The primary ways to select particular rows in a DataFrame are with the .loc and .iloc indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.

.loc selects data only by labels

We will first talk about the .loc indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length of the DataFrame.

There are three different inputs you can use for .loc

• A string
• A list of strings
• Slice notation using strings as the start and stop values

Selecting a single row with .loc with a string

To select a single row of data, place the index label inside of the brackets following .loc.

df.loc['Penelope']

This returns the row of data as a Series

age           4
color     white
food      Apple
height       80
score       3.3
state        AL
Name: Penelope, dtype: object

Selecting multiple rows with .loc with a list of strings

df.loc[['Cornelia', 'Jane', 'Dean']]

This returns a DataFrame with the rows in the order specified in the list:

Selecting multiple rows with .loc with slice notation

Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.

df.loc['Aaron':'Dean']

Complex slices can be taken in the same manner as Python lists.

.iloc selects data only by integer location

Let's now turn to .iloc. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.

There are three different inputs you can use for .iloc

• An integer
• A list of integers
• Slice notation using integers as the start and stop values

Selecting a single row with .iloc with an integer

df.iloc[4]

This returns the 5th row (integer location 4) as a Series

age           32
color       gray
food      Cheese
height       180
score        1.8
state         AK
Name: Dean, dtype: object

Selecting multiple rows with .iloc with a list of integers

df.iloc[[2, -2]]

This returns a DataFrame of the third and second to last rows:

Selecting multiple rows with .iloc with slice notation

df.iloc[:5:3]

Simultaneous selection of rows and columns with .loc and .iloc

One excellent ability of both .loc/.iloc is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.

For example, we can select rows Jane, and Dean with just the columns height, score and state like this:

df.loc[['Jane', 'Dean'], 'height':]

This uses a list of labels for the rows and slice notation for the columns

We can naturally do similar operations with .iloc using only integers.

df.iloc[[1,4], 2]
Nick      Lamb
Dean    Cheese
Name: food, dtype: object

Simultaneous selection with labels and integer location

.ix was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.

For instance, if we want to select rows Nick and Cornelia along with columns 2 and 4, we could use .loc by converting the integers to labels with the following:

col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names] 

Or alternatively, convert the index labels to integers with the get_loc index method.

labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]

Boolean Selection

The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows wher age is above 30 and return just the food and score columns we can do the following:

df.loc[df['age'] > 30, ['food', 'score']] 

You can replicate this with .iloc but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:

df.iloc[(df['age'] > 30).values, [2, 4]] 

Selecting all rows

It is possible to use .loc/.iloc for just column selection. You can select all the rows by using a colon like this:

df.loc[:, 'color':'score':2]

The indexing operator, [], can select rows and columns too but not simultaneously.

Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.

df['food']

Jane          Steak
Nick           Lamb
Aaron         Mango
Penelope      Apple
Dean         Cheese
Christina     Melon
Cornelia      Beans
Name: food, dtype: object

Using a list selects multiple columns

df[['food', 'score']]

What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.

df['Penelope':'Christina'] # slice rows by label

df[2:6:2] # slice rows by integer location

The explicitness of .loc/.iloc for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.

df[3:5, 'color']
TypeError: unhashable type: 'slice'

I do like TRAC - this plugin might be helpful for your task: http://trac-hacks.org/wiki/RepoSearchPlugin

sometimes you need to set Padding, not Margin to make space between items smaller than default

Built-in toLocaleDateString() does the job, but it will remove the leading 0s for the day and month, so we will get something like "1/9/1970", which is not perfect in my opinion. To get a proper format MM/DD/YYYY we can use something like:

new Date(dateString).toLocaleDateString('en-US', {
  day: '2-digit',
  month: '2-digit',
  year: 'numeric',
})

Both the following are set to "google_sdk":

Build.PRODUCT
Build.MODEL

So it should be enough to use either one of the following lines.

"google_sdk".equals(Build.MODEL)

or

"google_sdk".equals(Build.PRODUCT)

use pdb or ipdb. Diffrence between these two is ipdb supports auto complete.

for pdb

import pdb
pdb.set_trace()

for ipdb

import ipdb
ipdb.set_trace()

For executing new line hit n key, for continue hit c key. check more options by using help(pdb)

As I stated in comment i would use a box layout for this.

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout());

JButton button = new JButton("Button1");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button2");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button3");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

add(panel);

The best way to refresh entities in your context is to dispose your context and create a new one.

If you really need to refresh some entity and you are using Code First approach with DbContext class, you can use

    public static void ReloadEntity<TEntity>(
        this DbContext context, 
        TEntity entity)
        where TEntity : class
    {
        context.Entry(entity).Reload();
    }

To reload collection navigation properties, you can use

    public static void ReloadNavigationProperty<TEntity, TElement>(
        this DbContext context, 
        TEntity entity, 
        Expression<Func<TEntity, ICollection<TElement>>> navigationProperty)
        where TEntity : class
        where TElement : class
    {
        context.Entry(entity).Collection<TElement>(navigationProperty).Query();
    }

Reference: https://msdn.microsoft.com/en-us/library/system.data.entity.infrastructure.dbentityentry.reload(v=vs.113).aspx#M:System.Data.Entity.Infrastructure.DbEntityEntry.Reload

table {
    border-collapse: collapse;
}

td {
    padding-top: .5em;
    padding-bottom: .5em;
}

The cells won't react to anything unless you set the border-collapse first. You can also add borders to TR elements once that's set (among other things.)

If this is for layout, I'd move to using DIVs and more up-to-date layout techniques, but if this is tabular data, knock yourself out. I still make heavy use of tables in my web applications for data.

The pip download command lets you download packages without installing them:

pip download -r requirements.txt

(In previous versions of pip, this was spelled pip install --download -r requirements.txt.)

Then you can use pip install --no-index --find-links /path/to/download/dir/ -r requirements.txt to install those downloaded sdists, without accessing the network.

Thanks everyone! I modified Winand's code slightly to export it to the user's desktop, no matter who is using the worksheet. I gave credit in the code to where I got the idea (thanks Kyle).

Sub ExportImage()


Dim sFilePath As String
Dim sView As String

'Captures current window view
sView = ActiveWindow.View

'Sets the current view to normal so there are no "Page X" overlays on the image
ActiveWindow.View = xlNormalView

'Temporarily disable screen updating
Application.ScreenUpdating = False

Set Sheet = ActiveSheet

'Set the file path to export the image to the user's desktop
'I have to give credit to Kyle for this solution, found it here:
'http://stackoverflow.com/questions/17551238/vba-how-to-save-excel-workbook-to-desktop-regardless-of-user
sFilePath = CreateObject("WScript.Shell").specialfolders("Desktop") & "\" & ActiveSheet.Name & ".png"

'Export print area as correctly scaled PNG image, courtasy of Winand
zoom_coef = 100 / Sheet.Parent.Windows(1).Zoom
Set area = Sheet.Range(Sheet.PageSetup.PrintArea)
area.CopyPicture xlPrinter
Set chartobj = Sheet.ChartObjects.Add(0, 0, area.Width * zoom_coef, area.Height * zoom_coef)
chartobj.Chart.Paste
chartobj.Chart.Export sFilePath, "png"
chartobj.Delete

'Returns to the previous view
ActiveWindow.View = sView

'Re-enables screen updating
Application.ScreenUpdating = True

'Tells the user where the image was saved
MsgBox ("Export completed! The file can be found here:" & Chr(10) & Chr(10) & sFilePath)

End Sub

Merge conflicts happens when changes are made to a file at the same time. Here is how to solve it.

git CLI

Here are simple steps what to do when you get into conflicted state:

1. Note the list of conflicted files with: git status (under Unmerged paths section).

2. Solve the conflicts separately for each file by one of the following approaches:

   • Use GUI to solve the conflicts: git mergetool (the easiest way).

   • To accept remote/other version, use: git checkout --theirs path/file. This will reject any local changes you did for that file.

   • To accept local/our version, use: git checkout --ours path/file

     ^{However you've to be careful, as remote changes that conflicts were done for some reason.}

     Related: What is the precise meaning of "ours" and "theirs" in git?

   • Edit the conflicted files manually and look for the code block between <<<<</>>>>> then choose the version either from above or below =====. See: How conflicts are presented.

   • Path and filename conflicts can be solved by git add/git rm.

3. Finally, review the files ready for commit using: git status.

   If you still have any files under Unmerged paths, and you did solve the conflict manually, then let Git know that you solved it by: git add path/file.

4. If all conflicts were solved successfully, commit the changes by: git commit -a and push to remote as usual.

For practical tutorial, check: Scenario 5 - Fixing Merge Conflicts by Katacoda.

DiffMerge

I've successfully used DiffMerge which can visually compare and merge files on Windows, macOS and Linux/Unix.

It graphically can show the changes between 3 files and it allows automatic merging (when safe to do so) and full control over editing the resulting file.

^{Image source: DiffMerge (Linux screenshot)}

Simply download it and run in repo as:

git mergetool -t diffmerge .

macOS

On macOS you can install via:

brew install caskroom/cask/brew-cask
brew cask install diffmerge

And probably (if not provided) you need the following extra simple wrapper placed in your PATH (e.g. /usr/bin):

#!/bin/sh
DIFFMERGE_PATH=/Applications/DiffMerge.app
DIFFMERGE_EXE=${DIFFMERGE_PATH}/Contents/MacOS/DiffMerge
exec ${DIFFMERGE_EXE} --nosplash "$@"

Then you can use the following keyboard shortcuts:

• ?-Alt-Up/Down to jump to previous/next changes.
• ?-Alt-Left/Right to accept change from left or right

Alternatively you can use opendiff (part of Xcode Tools) which lets you merge two files or directories together to create a third file or directory.

Try looking at Double.TryParse() if you are using .NET 1.1/2.0/3.0/3.5/4.0/4.5

From Stack Overflow question What is the Python 3 equivalent of "python -m SimpleHTTPServer":

The following works for me:

python -m http.server [<portNo>]

Because I am using Python 3 the module SimpleHTTPServer has been replaced by http.server, at least in Windows.

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

Alternatively use the shortcut: place the cursor in the class, then press Alt + Shift + X to open up a context menu, then press J.

^wp.*\.php$ Should do the trick.

The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.

Using my 1.6KB library, you can do

ToString(FromUTF8(Array.from(usernameReceived)))

I think there's a simpler way. Create a hidden input with a random name (via javascript) and set the username to that. Repeat with the password. This way your backend script knows exactly what the appropriate field name is, while keeping autocomplete in the dark.

I'm probably wrong, but it's just an idea.

Finding the missing number from a series of numbers. IMP points to remember.

1. the array should be sorted..
2. the Function do not work on multiple missings.

3. the sequence must be an AP.

       public int execute2(int[] array) {
       int diff = Math.min(array[1]-array[0], array[2]-array[1]);
       int min = 0, max = arr.length-1;
       boolean missingNum = true;
       while(min<max) {
           int mid = (min + max) >>> 1;
           int leftDiff = array[mid] - array[min];
           if(leftDiff > diff * (mid - min)) {
               if(mid-min == 1)
                   return (array[mid] + array[min])/2;
               max = mid;
               missingNum = false;
               continue;
           }
           int rightDiff = array[max] - array[mid];
           if(rightDiff > diff * (max - mid)) {
               if(max-mid == 1)
                   return (array[max] + array[mid])/2;
               min = mid;
               missingNum = false;
               continue;
           }
           if(missingNum)
               break;
       }
       return -1;
   }
   

Use a comma ","

eg: 
UPDATE my_table SET rowOneValue = rowOneValue + 1, rowTwoValue  = rowTwoValue + ( (rowTwoValue / (rowTwoValue) ) + ?) * (v + 1) WHERE value = ?

forever package worked for me, just one thing, it depends on deep-equal, so if you had issue with installing it like:

npm -g install forever

Try:

npm -g install forever [email protected]

instead.

1. How can I do what I want to do (that is, initialize an array in a constructor (not assigning elements in the body)). Is it even possible?

Yes. It's using a struct that contains an array. You say you already know about that, but then I don't understand the question. That way, you do initialize an array in the constructor, without assignments in the body. This is what boost::array does.

Does the C++03 standard say anything special about initializing aggregates (including arrays) in ctor initializers? Or the invalidness of the above code is a corollary of some other rules?

A mem-initializer uses direct initialization. And the rules of clause 8 forbid this kind of thing. I'm not exactly sure about the following case, but some compilers do allow it.

struct A {
  char foo[6];
  A():foo("hello") { } /* valid? */
};

See this GCC PR for further details.

Do C++0x initializer lists solve the problem?

Yes, they do. However your syntax is invalid, I think. You have to use braces directly to fire off list initialization

struct A {
  int foo[3];
  A():foo{1, 2, 3} { }
  A():foo({1, 2, 3}) { } /* invalid */
};

Use this method (No need to xml file)

If you want scale to quarter(half x,half y)

view.animate().scaleX(0.5f).scaleY(0.5f)

If you want scale and move to bottom right

view.animate().scaleX(0.5f).scaleY(0.5f)
        .translationY((view.height/4).toFloat()).translationX((view.width/4).toFloat())

If you want move to top use (-view.height/4) and for left (-view.width/4)

If you want do something after animation ends use withEndAction(Runnable runnable) function.

You can use some other property like alpha and rotation

Full code

view.animate()
      .scaleX(0.5f).scaleY(0.5f)//scale to quarter(half x,half y)
      .translationY((view.height/4).toFloat()).translationX((view.width/4).toFloat())// move to bottom / right
      .alpha(0.5f) // make it less visible
      .rotation(360f) // one round turns
      .setDuration(1000) // all take 1 seconds
      .withEndAction(new Runnable() {
           @Override
           public void run() {
              //animation ended
           }
      });

You might just have to add a line feed "\n\r".

Here's an example:

SELECT * FROM pubs WHERE name LIKE "%John's%"

Just use double quotes to enclose the single quote.

If you insist in using single quotes (and the need to escape the character):

SELECT * FROM pubs WHERE name LIKE '%John\'s%'

This thread discusses how to install the binary on the simulator. I've done it and it works: http://forums.macrumors.com/showthread.php?t=547557

From the thread:

Look inside your ~/Library/Application Support/iPhone Simulator/User/Applications/ directory and see what happens inside this directory when you install and run apps using XCode, and also when you delete apps using the Simulator.

You can run the Simulator by itself (without starting XCode).

If you start the Simulator, delete an app, quit the Simulator, put back copies of the files that were deleted from the support directory, and restart the Simulator, the app will reappear in the Simulator. Email those files with instructions about how to copy them into the appropriate support directory.

You may try Code::Blocks, which is better IDE and comes with MinGW GCC! I have used it and its just too good a freeware IDE for C/C++.

this states that Account.deposit(Double.MAX_VALUE); it is setting deposit value to MAX value of Double dataType.to procced for running tests.

In my case, I did this to make the TextBlock display nicer.

<Border BorderThickness="3" BorderBrush="Yellow" CornerRadius="10" Padding="2"
    HorizontalAlignment="Center" VerticalAlignment="Center" Height="30" Width="150">
        <TextBlock FontSize="20" Height="23" HorizontalAlignment="Left" Margin="0,0,0,-5" Text="" VerticalAlignment="Top" Width="141" Background="White" />
</Border>

The trick to make the text further from the bottom is to set

Margin="0,0,0,-5"

I usually do this:

open(path_in_string, &:read)

This will give you the whole text as a string object. It works only under Ruby 1.9.

As other answers state setting new ParametersAction is the way to inject one or more environment variables, but when a job is already parameterised adding new action won't take effect. Instead you'll see two links to a build parameters pointing to the same set of parameters and the one you wanted to add will be null.

Here is a snippet updating the parameters list in both cases (a parametrised and non-parametrised job):

import hudson.model.*

def build = Thread.currentThread().executable

def env = System.getenv()
def version = env['currentversion']
def m = version =~/\d{1,2}/
def minVerVal = m[0]+"."+m[1]

def newParams = null

def pl = new ArrayList<StringParameterValue>()
pl.add(new StringParameterValue('miniVersion', miniVerVal))

def oldParams = build.getAction(ParametersAction.class)

if(oldParams != null) {
  newParams = oldParams.createUpdated(pl)
  build.actions.remove(oldParams)
} else {
  newParams = new ParametersAction(pl)
}

build.addAction(newParams)

I got NoClassDefFound errors when I didn't export a class on the "Order and Export" tab in the Java Build Path of my project. Make sure to put a checkmark in the "Order and Export" tab of any dependencies you add to the project's build path. See Eclipse warning: XXXXXXXXXXX.jar will not be exported or published.

Use it on activity onCreate (directory selection option is commented):

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    File mPath = new File(Environment.getExternalStorageDirectory() + "//DIR//");
    fileDialog = new FileDialog(this, mPath, ".txt");
    fileDialog.addFileListener(new FileDialog.FileSelectedListener() {
        public void fileSelected(File file) {
            Log.d(getClass().getName(), "selected file " + file.toString());
        }
    });
    //fileDialog.addDirectoryListener(new FileDialog.DirectorySelectedListener() {
    //  public void directorySelected(File directory) {
    //      Log.d(getClass().getName(), "selected dir " + directory.toString());
    //  }
    //});
    //fileDialog.setSelectDirectoryOption(false);
    fileDialog.showDialog();
}

Figured it out. This works:

DateTime.now.in_time_zone.midnight

HTA works like a normal windows application.
You write HTML code, and save it as an .hta file.

However, there are, at least, one drawback: The browser can't open an .hta file; it's handled as a normal .exe program. So, if you place a link to an .hta onto your web page, it will open a download dialog, asking of you want to open or save the HTA file. If its not a problem for you, you can click "Open" and it will open a new window (that have no toolbars, so no Back button, neither address bar, neither menubar).

I needed to do something very similar to what you want, but instead of iframes, I used a real frameset.
The main page need to be a .hta file; the other should be a normal .htm page (or .php or whatever).

Here's an example of a HTA page with 2 frames, where the top one have a button and a text field, that contains the second frame URL; the button updates the field:

frameset.hta

<html>
    <head>
        <title>HTA Example</title>
        <HTA:APPLICATION id="frames" border="thin" caption="yes" icon="http://www.google.com/favicon.ico" showintaskbar="yes" singleinstance="no" sysmenu="yes" navigable="yes" contextmenu="no" innerborder="no" scroll="auto" scrollflat="yes" selection="yes" windowstate="normal"></HTA:APPLICATION>
    </head>
    <frameset rows="60px, *">
        <frame src="topo.htm" name="topo" id="topo" application="yes" />
        <frame src="http://www.google.com" name="conteudo" id="conteudo" application="yes" />
    </frameset>
</html>

• There's an HTA:APPLICATION tag that sets some properties to the file; it's good to have, but it isn't a must.
• You NEED to place an application="yes" at the frames' tags. It says they belongs to the program too and should have access to all data (if you don't, the frames will still show the error you had before).

topo.htm

<html>
    <head>
        <title>Topo</title>
        <script type="text/javascript">
            function copia_url() {
                campo.value = parent.conteudo.location;
            }
        </script>
    </head>
    <body style="background: lightBlue;" onload="copia_url()">
        <input type="button" value="Copiar URL" onclick="copia_url()" />
        <input type="text" size="120" id="campo" />
    </body>
</html>

• You should notice that I didn't used any getElement function to fetch the field; on HTA file, all elements that have an ID becomes instantly an object

I hope this help you, and others that get to this question. It solved my problem, that looks like to be the same as you have.

I just found this thread and wanted to add to the discussion if the person doesn't want to use a batch file to restart services. In Windows there is an option if you go to Services, service properties, then recovery. Here you can set parameters for the service. Like to restart the service if the service stops. Also, you can even have a second fail attempt do something different as in restart the computer.

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

As @alucic mentioned, use:

composer require vendor/package:version

or you can use:

composer update vendor/package:version

You should probably review this StackOverflow post about differences between composer install and composer update.

Related to question about version numbers, you can review Composer documentation on versions, but here in short:

• Tilde Version Range (~) - ~1.2.3 is equivalent to >=1.2.3 <1.3.0
• Caret Version Range (^) - ^1.2.3 is equivalent to >=1.2.3 <2.0.0

So, with Tilde you will get automatic updates of patches but minor and major versions will not be updated. However, if you use Caret you will get patches and minor versions, but you will not get major (breaking changes) versions.

Tilde Version is considered a "safer" approach, but if you are using reliable dependencies (well-maintained libraries) you should not have any problems with Caret Version (because minor changes should not be breaking changes.

You cannot assign an rvalue to an rvalue.

if (strcmp("hello", "hello") = 0)

is wrong. Suggestions:

if (strcmp("hello", "hello") == 0)
                              ^

= is the assign operator.
== is the equal to operator.
I know many new programmers are confused with this fact.

I encountered the same ImportError. Somehow the setuptools package had been deleted in my Python environment.

To fix the issue, run the setup script for setuptools:

curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py | python

If you have any version of distribute, or any setuptools below 0.6, you will have to uninstall it first.*

See Installation Instructions for further details.

* If you already have a working distribute, upgrading it to the "compatibility wrapper" that switches you over to setuptools is easier. But if things are already broken, don't try that.

Found this one:

[x for (i,x) in enumerate(my_list) if my_list[i] == "two"]

Will print:

["two"]

This is short, yet efficient and proven approach:

location ~ (patternOne|patternTwo){ #rules etc. }

So one can easily have multiple patterns with simple pipe syntax pointing to the same location block / rules.

text_file = open("Output.txt", "w")
text_file.write("Purchase Amount: %s" % TotalAmount)
text_file.close()

If you use a context manager, the file is closed automatically for you

with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: %s" % TotalAmount)

If you're using Python2.6 or higher, it's preferred to use str.format()

with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: {0}".format(TotalAmount))

For python2.7 and higher you can use {} instead of {0}

In Python3, there is an optional file parameter to the print function

with open("Output.txt", "w") as text_file:
    print("Purchase Amount: {}".format(TotalAmount), file=text_file)

Python3.6 introduced f-strings for another alternative

with open("Output.txt", "w") as text_file:
    print(f"Purchase Amount: {TotalAmount}", file=text_file)

Besides the third party products listed here, there is another one: NetLib Encryptionizer. However it works in a different way than the obfuscators. Obfuscators modify the assembly itself with a deobfuscation "engine" built into it. Encryptionizer encrypts the DLLs (Managed or Unmanaged) at the file level. So it does not modify the DLL except to encrypt it. The "engine" in this case is a kernel mode driver that sits between your application and the operating system. (Disclaimer: I am from NetLib Security)

Here's the complete answer for the future reader. Note that this is only possible in Laravel 5+.

First of all you'll need the doctrine/dbal package:

composer require doctrine/dbal

Now in your migration you can do this to make the column nullable:

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        // change() tells the Schema builder that we are altering a table
        $table->integer('user_id')->unsigned()->nullable()->change();
    });
}

You may be wondering how to revert this operation. Sadly this syntax is not supported:

// Sadly does not work :'(
$table->integer('user_id')->unsigned()->change();

This is the correct syntax to revert the migration:

$table->integer('user_id')->unsigned()->nullable(false)->change();

Or, if you prefer, you can write a raw query:

public function down()
{
    /* Make user_id un-nullable */
    DB::statement('UPDATE `users` SET `user_id` = 0 WHERE `user_id` IS NULL;');
    DB::statement('ALTER TABLE `users` MODIFY `user_id` INTEGER UNSIGNED NOT NULL;');
}

Hopefully you'll find this answer useful. :)

To remove all OIDs from your database tables, you can use this Linux script:

First, login as PostgreSQL superuser:

sudo su postgres

Now run this script, changing YOUR_DATABASE_NAME with you database name:

for tbl in `psql -qAt -c "select schemaname || '.' || tablename from pg_tables WHERE schemaname <> 'pg_catalog' AND schemaname <> 'information_schema';" YOUR_DATABASE_NAME` ; do  psql -c "alter table $tbl SET WITHOUT OIDS" YOUR_DATABASE_NAME ; done

I used this script to remove all my OIDs, since Npgsql 3.0 doesn't work with this, and it isn't important to PostgreSQL anymore.

There is no public API for this yet. see Sun Bug 4244896, Sun Bug 4250622

As a workaround:

Runtime.exec(...)

returns an Object of type

java.lang.Process

The Process class is abstract, and what you get back is some subclass of Process which is designed for your operating system. For example on Macs, it returns java.lang.UnixProcess which has a private field called pid. Using Reflection you can easily get the value of this field. This is admittedly a hack, but it might help. What do you need the PID for anyway?

Two things to keep in mind Content-Type and the Encoding

1) What if the file is css

if (/.(css)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'text/css'}); 
  res.write(data, 'utf8');
} 

2) What if the file is jpg/png

if (/.(jpg)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'image/jpg'});
  res.end(data,'Base64');
}

Above one is just a sample code to explain the answer and not the exact code pattern.

This code will always fail.

As written, it says: "Look for a property named "Employee" on my DataContext property, and set it to the DataContext property". Clearly that isn't right.

To get your code to work, as is, change your window declaration to:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:SampleApplication"
    Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
   <local:Employee/>
</Window.DataContext>

This declares a new XAML namespace (local) and sets the DataContext to an instance of the Employee class. This will cause your bindings to display the default data (from your constructor).

However, it is highly unlikely this is actually what you want. Instead, you should have a new class (call it MainViewModel) with an Employee property that you then bind to, like this:

public class MainViewModel
{
   public Employee MyEmployee { get; set; } //In reality this should utilize INotifyPropertyChanged!
}

Now your XAML becomes:

<Window x:Class="SampleApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SampleApplication"
        Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
       <local:MainViewModel/>
    </Window.DataContext>
    ...
    <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding MyEmployee.EmpID}" />
    <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding MyEmployee.EmpName}" />

Now you can add other properties (of other types, names), etc. For more information, see Implementing the Model-View-ViewModel Pattern

In Rails:

"kirk douglas".titleize => "Kirk Douglas"
#this also works for 'kirk_douglas'

w/o Rails:

"kirk douglas".split(/ |\_/).map(&:capitalize).join(" ")

#OBJECT IT OUT
def titleize(str)
  str.split(/ |\_/).map(&:capitalize).join(" ")
end

#OR MONKEY PATCH IT
class String  
  def titleize
    self.split(/ |\_/).map(&:capitalize).join(" ")
  end
end

w/o Rails (load rails's ActiveSupport to patch #titleize method to String)

require 'active_support/core_ext'
"kirk douglas".titleize #=> "Kirk Douglas"

(some) string use cases handled by #titleize

• "kirk douglas"
• "kirk_douglas"
• "kirk-douglas"
• "kirkDouglas"
• "KirkDouglas"

#titleize gotchas

Rails's titleize will convert things like dashes and underscores into spaces and can produce other unexpected results, especially with case-sensitive situations as pointed out by @JamesMcMahon:

"hEy lOok".titleize #=> "H Ey Lo Ok"

because it is meant to handle camel-cased code like:

"kirkDouglas".titleize #=> "Kirk Douglas"

To deal with this edge case you could clean your string with #downcase first before running #titleize. Of course if you do that you will wipe out any camelCased word separations:

"kirkDouglas".downcase.titleize #=> "Kirkdouglas"

If you're stuck with Java 8 but have access to Guava 21.0 or newer, you can use Streams.stream to convert an optional into a stream.

Thus, given

import com.google.common.collect.Streams;

you can write

Optional<Other> result =
    things.stream()
        .map(this::resolve)
        .flatMap(Streams::stream)
        .findFirst();

you need to call the function like this

$this->assign()

instead of just assign()

At first shot, I could come up with something like this (but it's pseudo code and assuming you cannot use any .NET built-in libaries). Might require a bit of tweaking and re-thinking, but should be good enough for a head-start, maybe?

int findString(String var, String[] stringArray, int currentIndex, int stringMaxIndex)
    {
    if currentIndex > stringMaxIndex 
       return (-stringMaxIndex-1);
    else if var==arr[currentIndex] //or use any string comparison op or function
       return 0;
    else 
       return findString(var, stringArray, currentIndex++, stringMaxIndex) + 1 ;
    }



    //calling code
    int index = findString(var, arr, 0, getMaxIndex(arr));

    if index == -1 printOnScreen("Not found");
    else printOnScreen("Found on index: " + index);

I used following code on my sample application to start new activity.

Button next = (Button) findViewById(R.id.TEST);
next.setOnClickListener(new View.OnClickListener() {
    public void onClick(View view) {
        Intent myIntent = new Intent( view.getContext(), MyActivity.class);
        startActivityForResult(myIntent, 0);
    }
});

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

@Html.ActionLink("Edit", "edit", "markets",
    new { id = 1 },
    new {@class="ui-btn-right", data_icon="gear"})

becomes:

<form action="markets/Edit/1" class="ui-btn-right" data-icon="gear" .../>

As changing globally is somewhat risky, I was trying to increase max upload value for a single script big_file_upload.php. For some reason ini_set didn't help. After some reasearch I've come up with this. Put it in .htaccess (unless name changed via AccessFileName)

<If "%{REQUEST_URI} == '/subfolder/big_file_upload.php'" >
php_value upload_max_filesize 200M
php_value post_max_size 200M
</If>
<Else>
php_value upload_max_filesize 1M
php_value post_max_size 1M
</Else>

Worked for me.

hi here i posted one video ,and it explains how to generate unique random number

  public List<int> random_generator(){

  Random random = new Random();

   List<int> random_container = new List<int>;

     do{

       int random_number = random.next(10);

      if(!random_container.contains(random_number){

       random_container.add(random_number)
  }
}
   while(random_container.count!=10);


     return random_container; 
  }

here ,,, in random container you will get non repeated 10 numbers starts from 0 to 9(10 numbers) as random.. thank you........

this is pretty old, but if you are using Python 3.4 or above use PathLib.

# using OS
import os
path=os.path.dirname("C:/folder1/folder2/filename.xml")
print(path)
print(os.path.basename(path))

# using pathlib
import pathlib
path = pathlib.PurePath("C:/folder1/folder2/filename.xml")
print(path.parent)
print(path.parent.name)

Use a wildcard (*) to match multiple files.

For example, the command below will delete all files with names beginning with abc.log.2012-03-.

rm -f abc.log.2012-03-*

I'd recommend running ls abc.log.2012-03-* to list the files so that you can see what you are going to delete before running the rm command.

For more details see the Bash man page on filename expansion.

on the other side of the coin, you should use "non-char" regex that looks like this if special characters = allChars - number - ABC - space in your app context.

String regepx = "[^\\s\\w]*";

I think it's the button "active" state.

The output file needs to be opened in binary mode:

f = open('varstor.txt','w')

needs to be:

f = open('varstor.txt','wb')

Depending on which event you actually want to use (textbox change, or button click), you can try this:

HTML:

<input id="color" type="text" onchange="changeBackground(this);" />
<br />
<span id="coltext">This text should have the same color as you put in the text box</span>

JS:

function changeBackground(obj) {
    document.getElementById("coltext").style.color = obj.value;
}

DEMO: http://jsfiddle.net/6pLUh/

One minor problem with the button was that it was a submit button, in a form. When clicked, that submits the form (which ends up just reloading the page) and any changes from JavaScript are reset. Just using the onchange allows you to change the color based on the input.

 int index_selected = radio_grp.indexOfChild(radio_grp
                .findViewById(radio_grp.getCheckedRadioButtonId()));

Static variable in a header file:

say 'common.h' has

static int zzz;

This variable 'zzz' has internal linkage (This same variable can not be accessed in other translation units). Each translation unit which includes 'common.h' has it's own unique object of name 'zzz'.

Static variable in a class:

Static variable in a class is not a part of the subobject of the class. There is only one copy of a static data member shared by all the objects of the class.

$9.4.2/6 - "Static data members of a class in namespace scope have external linkage (3.5).A local class shall not have static data members."

So let's say 'myclass.h' has

struct myclass{
   static int zzz;        // this is only a declaration
};

and myclass.cpp has

#include "myclass.h"

int myclass::zzz = 0           // this is a definition, 
                               // should be done once and only once

and "hisclass.cpp" has

#include "myclass.h"

void f(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

and "ourclass.cpp" has

#include "myclass.h"
void g(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

So, class static members are not limited to only 2 translation units. They need to be defined only once in any one of the translation units.

Note: usage of 'static' to declare file scope variable is deprecated and unnamed namespace is a superior alternate

Here's an approach which (ab)uses vim:

vim -c :sort -c :wq -E -s "${filename}"

The -c :sort -c :wq portion invokes commands to vim after the file opens. -E and -s are necessary so that vim executes in a "headless" mode which doesn't draw to the terminal.

This has almost no benefits over the sort -o "${filename}" "${filename}" approach except that it only takes the filename argument once.

This was useful for me to implement a formatter directive in a nanorc entry for .gitignore files. Here's what I used for that:

syntax "gitignore" "\.gitignore$"

formatter vim -c :sort -c :wq -E -s

I use this little PowerShell snippet:

function Get-SystemUptime {
    $operatingSystem = Get-WmiObject Win32_OperatingSystem
    "$((Get-Date) - ([Management.ManagementDateTimeConverter]::ToDateTime($operatingSystem.LastBootUpTime)))"
}

which then yields something like the following:

PS> Get-SystemUptime
6.20:40:40.2625526

GetUserId() is an extension method on IIdentity and it is in Microsoft.AspNet.Identity.IdentityExtensions. Make sure you have added the namespace with using Microsoft.AspNet.Identity;.

Add "watch": "nodemon --exec ts-node -- ./src/index.ts" to scripts section of your package.json.

This should be as simple as:

with open('somefile.txt', 'a') as the_file:
    the_file.write('Hello\n')

From The Documentation:

Do not use os.linesep as a line terminator when writing files opened in text mode (the default); use a single '\n' instead, on all platforms.

Some useful reading:

• The with statement
• open()
  • 'a' is for append, or use
  • 'w' to write with truncation
• os (particularly os.linesep)

These solutions totally make sense. Unfortunately, neither worked for me as expected. Instead of trying to hassle with it, I went with a work around:

select * from information_schema.columns 
where replace(table_name,'_','!') not like '%!%'
order by table_name

An easy, loop-free alternative is to use the horizontalalignment Text property as a keyword argument to xticks[1]. In the below, at the commented line, I've forced the xticks alignment to be "right".

n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')

plt.xticks(
        [0,1,2,3,4],
        ["this label extends way past the figure's left boundary",
        "bad motorfinger", "green", "in the age of octopus diplomacy", "x"], 
        rotation=45,
        horizontalalignment="right")    # here
plt.show()

(yticks already aligns the right edge with the tick by default, but for xticks the default appears to be "center".)

[1] You find that described in the xticks documentation if you search for the phrase "Text properties".

The dependencies syntax is located at the Dependency Version Requirement Specification documentation. Here it is is for completeness:

Dependencies' version element define version requirements, used to compute effective dependency version. Version requirements have the following syntax:

• 1.0: "Soft" requirement on 1.0 (just a recommendation, if it matches all other ranges for the dependency)
• [1.0]: "Hard" requirement on 1.0
• (,1.0]: x <= 1.0
• [1.2,1.3]: 1.2 <= x <= 1.3
• [1.0,2.0): 1.0 <= x < 2.0
• [1.5,): x >= 1.5
• (,1.0],[1.2,): x <= 1.0 or x >= 1.2; multiple sets are comma-separated
• (,1.1),(1.1,): this excludes 1.1 (for example if it is known not to work in combination with this library)

In your case, you could do something like <version>[1.2.3,)</version>

Go on using tabTextAppearance as you did but

1) to fix the capital letter side effect add textAllCap in your style :

<style name="MyTabLayoutTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse">
    <item name="android:textSize">14sp</item>
    <item name="android:textAllCaps">true</item>
</style>

2) to fix the selected tab color side effect add in TabLayout xml the following library attributes :

app:tabSelectedTextColor="@color/color1"
app:tabTextColor="@color/color2" 

Hope this helps.

Yes, tasks waiting for IO are blocked, and other tasks get executed. Selecting the next task is done by the Linux scheduler.

#include <stdio.h>
main()
{
    char str[100];
    int num;
    while(1) {
        printf("Enter a number: ");
        scanf("%[^0-9]%d",str,&num);
        printf("You entered the number %d\n",num);
    }
    return 0;
}

%[^0-9] in scanf() gobbles up all that is not between 0 and 9. Basically it cleans the input stream of non-digits and puts it in str. Well, the length of non-digit sequence is limited to 100. The following %d selects only integers in the input stream and places it in num.

To simplify things here's a jQuery plugin that can achieve this goal : https://github.com/haggen/readonly

1. Include readonly.js in your project. (also needs jquery)

2. Replace .attr('readonly', 'readonly') with .readonly() instead. That's it.

   For example, change from $(".someClass").attr('readonly', 'readonly'); to $(".someClass").readonly();.

I had this issue occurring with mailto: and tel: links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.

Adding target="_blank", as suggested by this discussion of the issue fixed the problem for me.

When sending data to a web server, the data has to be a string (here). You can convert a JavaScript object into a string with JSON.stringify(). Here is a working example:

var fs = require('fs');

var originalNote = {
  title: 'Meeting',
  description: 'Meeting John Doe at 10:30 am'
};

var originalNoteString = JSON.stringify(originalNote);

fs.writeFileSync('notes.json', originalNoteString);

var noteString = fs.readFileSync('notes.json');

var note = JSON.parse(noteString);

console.log(`TITLE: ${note.title} DESCRIPTION: ${note.description}`);

Hope it could help.

If it is native code, you can disassemble it. But you wont see the original code as writte by the programmer. You will see the code produces by the compiler (assembler). This code is possibly optimized and although it is semantically equivalent, it can be much harder to read than normal ASM.

If it is bytecode (MSIL or javabytecode), there are decompiler which can product pretty good sourcecode. For .net, this would be reflector.

This code:

Option Explicit

Sub ExportMyPicture()

     Dim MyChart As String, MyPicture As String
     Dim PicWidth As Long, PicHeight As Long

     Application.ScreenUpdating = False
     On Error GoTo Finish

     MyPicture = Selection.Name
     With Selection
           PicHeight = .ShapeRange.Height
           PicWidth = .ShapeRange.Width
     End With

     Charts.Add
     ActiveChart.Location Where:=xlLocationAsObject, Name:="Sheet1"
     Selection.Border.LineStyle = 0
     MyChart = Selection.Name & " " & Split(ActiveChart.Name, " ")(2)

     With ActiveSheet
           With .Shapes(MyChart)
                 .Width = PicWidth
                 .Height = PicHeight
           End With

           .Shapes(MyPicture).Copy

           With ActiveChart
                 .ChartArea.Select
                 .Paste
           End With

           .ChartObjects(1).Chart.Export Filename:="MyPic.jpg", FilterName:="jpg"
           .Shapes(MyChart).Cut
     End With

     Application.ScreenUpdating = True
     Exit Sub

Finish:
     MsgBox "You must select a picture"
End Sub

was copied directly from here, and works beautifully for the cases I tested.

Also, if you want cellspacing="0", don't forget to add border-collapse: collapse in your table's stylesheet.

For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.

I was facing this error because I tried to compare two dates using the following Method

var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator

However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.

Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime() method was simply not added to the prototype.

Solution

In this case, recreating a date-Object based on your dates will fix the issue.

var res = new Date(dat1).getTime() > new Date(dat2).getTime()

Edit:

I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.

The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.

class Details {
    description: string;
    date: Date;
    score: number;
    approved: boolean;

    constructor(data: any) {
      Object.assign(this, data);
    }
}

and to perform the mapping:

public getDetails(id: number): Promise<Details> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details/${id}`)
               .map(response => new Details(response.json()))
               .toPromise();
}

for arrays use:

public getDetails(): Promise<Details[]> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details`)
               .map(response => {
                   const array = JSON.parse(response.json()) as any[];
                   const details = array.map(data => new Details(data));
                   return details;
               })
               .toPromise();
}

For two way communication with named pipes:

• If you have few processes, you can open two pipes for two directions (processA2ProcessB and processB2ProcessA)
• If you have many processes, you can open in and out pipes for every process (processAin, processAout, processBin, processBout, processCin, processCout etc)
• Or you can go hybrid as always :)

Named pipes are quite easy to implement.

E.g. I implemented a project in C with named pipes, thanks to standart file input-output based communication (fopen, fprintf, fscanf ...) it was so easy and clean (if that is also a consideration).

I even coded them with java (I was serializing and sending objects over them!)

Named pipes has one disadvantage:

• they do not scale on multiple computers like sockets since they rely on filesystem (assuming shared filesystem is not an option)

A pull request is just that: a request to merge one branch into another.

Your pull request doesn't "contain" anything, it's just a marker saying "please merge this branch into that one".

The set of changes the PR shows in the web UI is just the changes between the target branch and your feature branch. To modify your pull request, you must modify your feature branch, probably with a force push to the feature branch.

In your case, you'll probably want to amend your commit. Not sure about your exact situation, but some combination of interactive rebase and add -p should sort you out.

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

The following res: (resource) references need to point to your model.

<add name="Entities" connectionString="metadata=
    res://*/Models.WraithNath.co.uk.csdl|
    res://*/Models.WraithNath.co.uk.ssdl|
    res://*/Models.WraithNath.co.uk.msl;

Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).

It also may help to specify the assembly rather than using "//*/".

Worst case, you can check everything (a bit slower but should always find the resource) by using

<add name="Entities" connectionString="metadata=
        res://*/;provider= <!-- ... -->

1 workaround to solve this problem is:

1. Download the notebook which you are not able to save by going to: File --> Download as --> Notebook (ipynb).

2. Open the downloaded notebook by clicking on the downloaded file on the jupyter browser UI

Now, you should be able to save (or rename) this notebook from jupyter UI

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

The != operator most certainly does exist! It is an alias for the standard <> operator.

Perhaps your fields are not actually empty strings, but instead NULL?

To compare to NULL you can use IS NULL or IS NOT NULL or the null safe equals operator <=>.

This is actually a fairly interesting question. It's not as simple as it looks at first. For reference, I'm going to be basing this off of the latest C11 language grammar defined in N1570

I guess the counter-intuitive part of the question is: if this is correct C:

if (a == 1) {
  int b = 10;
}

then why is this not also correct C?

if (a == 1)
  int b = 10;

I mean, a one-line conditional if statement should be fine either with or without braces, right?

The answer lies in the grammar of the if statement, as defined by the C standard. The relevant parts of the grammar I've quoted below. Succinctly: the int b = 10 line is a declaration, not a statement, and the grammar for the if statement requires a statement after the conditional that it's testing. But if you enclose the declaration in braces, it becomes a statement and everything's well.

And just for the sake of answering the question completely -- this has nothing to do with scope. The b variable that exists inside that scope will be inaccessible from outside of it, but the program is still syntactically correct. Strictly speaking, the compiler shouldn't throw an error on it. Of course, you should be building with -Wall -Werror anyways ;-)

In contribution to ellabeauty's answer. you can also use this dynamic percentage values

$('.bar').css('width',  function(){ return ($(this).attr('data-percentage')+'%')});

And probably add custom easing to your css

.bar {
 -webkit-transition: width 2.50s ease !important;
 -moz-transition: width 2.50s ease !important;
   -o-transition: width 2.50s ease !important;
      transition: width 2.50s ease !important;
 }

Date and time input is accepted in almost any reasonable format, including ISO 8601, SQL-compatible, traditional POSTGRES, and others. For some formats, ordering of month, day, and year in date input is ambiguous and there is support for specifying the expected ordering of these fields.

In other words: just write anything and it will work.

Or check this table with all the unambiguous formats.

Kenny is right, just want to clear some things out.

1. Create the file border.xml and put it in the folder res/drawable/

2. add the code

   <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
      <stroke android:width="4dp" android:color="#FF00FF00" /> 
      <solid android:color="#ffffff" /> 
      <padding android:left="7dp" android:top="7dp" 
           android:right="7dp" android:bottom="0dp" /> 
      <corners android:radius="4dp" /> 
   </shape>
   

3. set back ground like android:background="@drawable/border" wherever you want the border

Mine first didn't work cause i put the border.xml in the wrong folder!

When you just remove a map, it destroys the div id reference, so, after remove() you need to build again the div where the map will be displayed, in order to avoid the "Uncaught Error: Map container not found".

if(map != undefined || map != null){
    map.remove();
   $("#map").html("");
   $("#preMap").empty();
   $( "<div id=\"map\" style=\"height: 500px;\"></div>" ).appendTo("#preMap");
}

private doesn't seem to work if you are defining a method on an explicit object (in your case self). You can use private_class_method to define class methods as private (or like you described).

class Person
  def self.get_name
    persons_name
  end

  def self.persons_name
    "Sam"
  end

  private_class_method :persons_name
end

puts "Hey, " + Person.get_name
puts "Hey, " + Person.persons_name

Alternatively (in ruby 2.1+), since a method definition returns a symbol of the method name, you can also use this as follows:

class Person
  def self.get_name
    persons_name
  end

  private_class_method def self.persons_name
    "Sam"
  end
end

puts "Hey, " + Person.get_name
puts "Hey, " + Person.persons_name

Flags (or compiler options) are nothing but ordinary command line arguments passed to the compiler executable.

Assuming you are invoking g++ from the command line (terminal):

$ g++ -std=c++11 your_file.cpp -o your_program

or

$ g++ -std=c++0x your_file.cpp -o your_program

if the above doesn't work.

quick solution could be:

SELECT your_db_column_name from "your_db_schema_name"."your_db_tabel_name";

mysqli_set_charset($con,"utf8");
$title = ' LEVEL – EXTENDED'; 
$newtitle = preg_replace('/[^(\x20-\x7F)]*/','', $title);     
echo $newtitle;

Result :  LEVEL EXTENDED

Many Strange Character be removed by applying below the mysql connection code. but in some circumstances of removing this type strange character like †you can use preg_replace above format.

Adding to @Luca Davanzo

iOS 11, some permissions settings have moved to the app path:

iOS 11 Support

 static func open(_ preferenceType: PreferenceType) throws {
    var preferencePath: String
    if #available(iOS 11.0, *), preferenceType == .video || preferenceType == .locationServices || preferenceType == .photos {
        preferencePath = UIApplicationOpenSettingsURLString
    } else {
        preferencePath = "\(PreferencesExplorer.preferencePath)=\(preferenceType.rawValue)"
    }

    if let url = URL(string: preferencePath) {
        if #available(iOS 10.0, *) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(url)
        }
    } else {
        throw PreferenceExplorerError.notFound(preferencePath)
    }
}

In my case, I got this no cipher suites in common error because I've loaded a p12 format file to the keystore of the server, instead of a jks file.

You are working way too hard. Your entire script should be:

if mkdir "$lockdir" 2> /dev/null; then 
  echo lock acquired
else
  echo could not acquire lock >&2
fi

but even that is probably too verbose. I would code it:

mkdir "$lockdir" || exit 1

but the resulting error message is a bit obscure.

As John Weldon said all members must be static in a static class. Try

public static class employee
{
     static NameValueCollection appSetting = ConfigurationManager.AppSettings;    

}

If your goal is to simply display some static files you can use the Connect package. I have had some success (I'm still pretty new to NodeJS myself), using it and the twitter bootstrap API in combination.

at the command line

:\> cd <path you wish your server to reside>
:\> npm install connect

Then in a file (I named) Server.js

var connect = require('connect'),
   http = require('http');
connect()
   .use(connect.static('<pathyouwishtoserve>'))
   .use(connect.directory('<pathyouwishtoserve>'))
   .listen(8080);

Finally

:\>node Server.js

Caveats:

If you don't want to display the directory contents, exclude the .use(connect.directory line.

So I created a folder called "server" placed index.html in the folder and the bootstrap API in the same folder. Then when you access the computers IP:8080 it's automagically going to use the index.html file.

If you want to use port 80 (so just going to http://, and you don't have to type in :8080 or some other port). you'll need to start node with sudo, I'm not sure of the security implications but if you're just using it for an internal network, I don't personally think it's a big deal. Exposing to the outside world is another story.

Update 1/28/2014:

I haven't had to do the following on my latest versions of things, so try it out like above first, if it doesn't work (and you read the errors complaining it can't find nodejs), go ahead and possibly try the below.

End Update

Additionally when running in ubuntu I ran into a problem using nodejs as the name (with NPM), if you're having this problem, I recommend using an alias or something to "rename" nodejs to node.

Commands I used (for better or worse):

Create a new file called node

:\>gedit /usr/local/bin/node
#!/bin/bash
exec /nodejs "$@"

sudo chmod -x /usr/local/bin/node

That ought to make

node Server.js 

work just fine

Here's a fun solution:

/**
 * Filter-map. Like map, but skips undefined values.
 *
 * @param callback
 */
function fmap(callback) {
    return this.reduce((accum, ...args) => {
        let x = callback(...args);
        if(x !== undefined) {
            accum.push(x);
        }
        return accum;
    }, []);
}

Use with the bind operator:

[1,2,-1,3]::fmap(x => x > 0 ? x * 2 : undefined); // [2,4,6]

If you can do this in java, try:

RuntimeMXBean

ManagementFactory

Example:

RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();
List<String> jvmArgs = runtimeMXBean.getInputArguments();
for (String arg : jvmArgs) {
    System.out.println(arg);
}

In regards to Gordon M's answer above, the 1st and 2nd parameter in mysqli_real_escape_string () call should be swapped for the newer php versions, according to: http://php.net/manual/en/mysqli.real-escape-string.php

Firefox simply does not show custom onbeforeunload messages. Mozilla say they are protecing end users from malicious sites that might show misleading text.

Problems

Image representing will take a lot of cpu and memory resources. So, in this case it is better to follow several rules:

- do not run jpegData(compressionQuality:) on main queue

- run only one jpegData(compressionQuality:) simultaneously

Wrong:

for i in 0...50 {
    DispatchQueue.global(qos: .utility).async {
        let quality = 0.02 * CGFloat(i)
        //let data = image.toJpegData(compressionQuality: quality)
        let data = image.jpegData(compressionQuality: quality)
        let size = CGFloat(data!.count)/1000.0/1024.0
        print("\(i), quality: \(quality), \(size.rounded()) mb")
    }
}

Right:

let serialQueue = DispatchQueue(label: "queue", qos: .utility, attributes: [], autoreleaseFrequency: .workItem, target: nil)

for i in 0...50 {
    serialQueue.async {
        let quality = 0.02 * CGFloat(i)
        //let data = image.toJpegData(compressionQuality: quality)
        let data = image.jpegData(compressionQuality: quality)
        let size = CGFloat(data!.count)/1000.0/1024.0
        print("\(i), quality: \(quality), \(size.rounded()) mb")
    }

The If else statement needs to be wrapped in a .get or a .post to redirect. Such as

app.post('/login', function(req, res) {

or

app.get('/login', function(req, res) {

My guess is that ServiceUser.method() is itself transactional. It shouldn't be. Here's the reason why.

Here's what happens when a call is made to your ServiceUser.method() method:

1. the transactional interceptor intercepts the method call, and starts a transaction, because no transaction is already active
2. the method is called
3. the method calls MyService.doSth()
4. the transactional interceptor intercepts the method call, sees that a transaction is already active, and doesn't do anything
5. doSth() is executed and throws an exception
6. the transactional interceptor intercepts the exception, marks the transaction as rollbackOnly, and propagates the exception
7. ServiceUser.method() catches the exception and returns
8. the transactional interceptor, since it has started the transaction, tries to commit it. But Hibernate refuses to do it because the transaction is marked as rollbackOnly, so Hibernate throws an exception. The transaction interceptor signals it to the caller by throwing an exception wrapping the hibernate exception.

Now if ServiceUser.method() is not transactional, here's what happens:

1. the method is called
2. the method calls MyService.doSth()
3. the transactional interceptor intercepts the method call, sees that no transaction is already active, and thus starts a transaction
4. doSth() is executed and throws an exception
5. the transactional interceptor intercepts the exception. Since it has started the transaction, and since an exception has been thrown, it rollbacks the transaction, and propagates the exception
6. ServiceUser.method() catches the exception and returns

As a new user to these two software packages, I experienced the exact same problem. As was also discovered above, my solution was to use the same case letters as is in the Repository path.

Here's a tip that I find helpful: In VisualSVN, you can right click on the path, then click "Copy URL to Clipboard" for pasting in Tortoise to be sure that the path is the identical case.

Here a function that works without libraries and returns a Promise:

/**
 * converts a base64 encoded data url SVG image to a PNG image
 * @param originalBase64 data url of svg image
 * @param width target width in pixel of PNG image
 * @return {Promise<String>} resolves to png data url of the image
 */
function base64SvgToBase64Png (originalBase64, width) {
    return new Promise(resolve => {
        let img = document.createElement('img');
        img.onload = function () {
            document.body.appendChild(img);
            let canvas = document.createElement("canvas");
            let ratio = (img.clientWidth / img.clientHeight) || 1;
            document.body.removeChild(img);
            canvas.width = width;
            canvas.height = width / ratio;
            let ctx = canvas.getContext("2d");
            ctx.drawImage(img, 0, 0, canvas.width, canvas.height);
            try {
                let data = canvas.toDataURL('image/png');
                resolve(data);
            } catch (e) {
                resolve(null);
            }
        };
        img.src = originalBase64;
    });
}

On Firefox there is an issue for SVGs without set width / height.

See this working example including a fix for the Firefox issue.

Keystore only has one password. You can change it using keytool:

keytool -storepasswd -keystore my.keystore

To change the key's password:

keytool -keypasswd  -alias <key_name> -keystore my.keystore

ggplot2 and scales packages can do that:

y <- c(12, 20)/100
x <- c(1, 2)

library(ggplot2)
library(scales)
myplot <- qplot(as.factor(x), y, geom="bar")
myplot + scale_y_continuous(labels=percent)

It seems like the stat() option has been taken off, causing the error message. Try this:

library(scales)

myplot <- ggplot(mtcars, aes(factor(cyl))) + 
          geom_bar(aes(y = (..count..)/sum(..count..))) + 
          scale_y_continuous(labels=percent)

myplot

I think it works the other way

<#if object.attribute??>
   Do whatever you want....

If object.attribute is NOT NULL, then the content will be printed.

I wanted to see all the indices for the colnames because I needed to do a complicated column rearrangement, so I printed the colnames as a dataframe. The rownames are the indices.

as.data.frame(colnames(df))

Solution :

login as sysdaba:

sqlplus  / as sysdba

then:

sql>Shutdown immediate;

sql>startup restrict;

sql>drop user TEST cascade;

If you want to re-activate DB normally either reset the server or :

sql>Shutdown immediate;

sql>startup;

Assign the second variable for the $.each function() as well, makes it lot easier as it'll provide you the data (so you won't have to work with the indicies).

$.each(json, function(arrayID,group) {
            console.log('<a href="'+group.GROUP_ID+'">');
    $.each(group.EVENTS, function(eventID,eventData) {
            console.log('<p>'+eventData.SHORT_DESC+'</p>');
     });
});

Should print out everything you were trying in your question.

http://jsfiddle.net/niklasvh/hZsQS/

edit renamed the variables to make it bit easier to understand what is what.

Bad idea, don't do it ever - but here it is how it can be done:

int main()
{
   A aObj;
   int* ptr;

   ptr = (int*)&aObj;

   // MODIFY!
   *ptr = 100;
}

The complete way would be:

bool b1;
bool? b2 = ???;
if (b2.HasValue)
   b1 = b2.Value;

Or you can test for specific values using

bool b3 = (b2 == true); // b2 is true, not false or null

Besides the technical implications of static vs dynamic libraries (static files bundle everything in one big binary vs dynamic libraries that allow code sharing among several different executables), there are the legal implications.

For example, if you are using LGPL licensed code and you link statically against a LGPL library (and thus create one big binary), your code automatically becomes Open Sourced (free as in freedom) LGPL code. If you link against a shared objects, then you only need to LGPL the improvements / bug fixes that you make to the LGPL library itself.

This becomes a far more important issue if you are deciding how to compile you mobile applications for example (in Android you have a choice of static vs dynamic, in iOS you do not - it is always static).

I simply added in first function

parentThis = this;

and use parentThis in subfunction. Why? Because in JavaScript, objects are soft. A new member can be added to a soft object by simple assignment (not like ie. Java where classical objects are hard. The only way to add a new member to a hard object is to create a new class) More on this here: http://www.crockford.com/javascript/inheritance.html

And also at the end you don't have to kill or destroy the object. Why I found here: http://bytes.com/topic/javascript/answers/152552-javascript-destroy-object

This is more of a rare issue but I have seen this if someone has copied the entire /var/lib/mysql directory as a way of migrating their DB to another server. The reason it doesn't work is because the database was running and using log files. It doesn't work sometimes if there are logs in /var/log/mysql. The solution is to copy the /var/log/mysql files as well.

Double quotes can be achieved using VBA in one of two ways

First one is often the best

One of the aspects of .NET I like the most are generics. Even if you write procedural code in F#, you will still benefit from type inference. It makes writing generic code easy.

In C#, you write concrete code by default, and you have to put in some extra work to write generic code.

In F#, you write generic code by default. After spending over a year of programming in both F# and C#, I find that library code I write in F# is both more concise and more generic than the code I write in C#, and is therefore also more reusable. I miss many opportunities to write generic code in C#, probably because I'm blinded by the mandatory type annotations.

There are however situations where using C# is preferable, depending on one's taste and programming style.

• C# does not impose an order of declaration among types, and it's not sensitive to the order in which files are compiled.
• C# has some implicit conversions that F# cannot afford because of type inference.

This type of Notification is deprecated as seen from documents:

@java.lang.Deprecated
public Notification(int icon, java.lang.CharSequence tickerText, long when) { /* compiled code */ }

public Notification(android.os.Parcel parcel) { /* compiled code */ }

@java.lang.Deprecated
public void setLatestEventInfo(android.content.Context context, java.lang.CharSequence contentTitle, java.lang.CharSequence contentText, android.app.PendingIntent contentIntent) { /* compiled code */ }

Better way
You can send a notification like this:

// prepare intent which is triggered if the
// notification is selected

Intent intent = new Intent(this, NotificationReceiver.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);

// build notification
// the addAction re-use the same intent to keep the example short
Notification n  = new Notification.Builder(this)
        .setContentTitle("New mail from " + "[email protected]")
        .setContentText("Subject")
        .setSmallIcon(R.drawable.icon)
        .setContentIntent(pIntent)
        .setAutoCancel(true)
        .addAction(R.drawable.icon, "Call", pIntent)
        .addAction(R.drawable.icon, "More", pIntent)
        .addAction(R.drawable.icon, "And more", pIntent).build();


NotificationManager notificationManager = 
  (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

notificationManager.notify(0, n); 

Best way
Code above needs minimum API level 11 (Android 3.0).
If your minimum API level is lower than 11, you should you use support library's NotificationCompat class like this.

So if your minimum target API level is 4+ (Android 1.6+) use this:

    import android.support.v4.app.NotificationCompat;
    -------------
    NotificationCompat.Builder builder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.mylogo)
                    .setContentTitle("My Notification Title")
                    .setContentText("Something interesting happened");
    int NOTIFICATION_ID = 12345;

    Intent targetIntent = new Intent(this, MyFavoriteActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, targetIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    NotificationManager nManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    nManager.notify(NOTIFICATION_ID, builder.build());

Open the XAMMP php.ini file (the default path is C:\xammp\php\php.ini) and change the code (;extension=ldap) to extension=php_ldap.dll and save. Restart XAMMP and save.

;
; - Many DLL files are located in the extensions/ (PHP 4) or ext/ (PHP 5+)
;   extension folders as well as the separate PECL DLL download (PHP 5+).

You can use the npm modules jsdom and htmlparser to create and parse a DOM in Node.JS.

Other options include:

• BeautifulSoup for python
• you can convert you html to xhtml and use XSLT
• HTMLAgilityPack for .NET
• CsQuery for .NET (my new favorite)
• The spidermonkey and rhino JS engines have native E4X support. This may be useful, only if you convert your html to xhtml.

Out of all these options, I prefer using the Node.js option, because it uses the standard W3C DOM accessor methods and I can reuse code on both the client and server. I wish BeautifulSoup's methods were more similar to the W3C dom, and I think converting your HTML to XHTML to write XSLT is just plain sadistic.

as you can see on the answer to this question: Conversion of a varchar data type to a datetime data type resulted in an out-of-range value

-- set the dateformat for the current session
set dateformat dmy

-- The conversion of a varchar data type 
-- to a datetime data type resulted in an out-of-range value.
select cast('2017-08-13 16:31:31'  as datetime)

-- get the current session date_format
select date_format
from sys.dm_exec_sessions
where session_id = @@spid

-- set the dateformat for the current session
set dateformat ymd

-- this should work
select cast('2017-08-13 16:31:31'  as datetime)

Don't forget to bind key attribute otherwise always last item will be deleted

Correct way to delete selected item from array:

Template

<div v-for="(item, index) in items" :key="item.id">
  <input v-model="item.value">
   <button @click="deleteItem(index)">
  delete
</button>

script

deleteItem(index) {
  this.items.splice(index, 1); \\OR   this.$delete(this.items,index)
 \\both will do the same
}

Introduction

For reference I'd like to include my variation on VonC's answer. Keep in mind that I am using the MSys version of Git (1.6.0.2 at this time) with modified PATH, and running Git itself from Powershell (or cmd.exe), not the Bash shell.

I introduced a new command, gitdiff. Running this command temporarily redirects git diff to use a visual diff program of your choice (as opposed to VonC's solution that does it permanently). This allows me to have both the default Git diff functionality (git diff) as well as visual diff functionality (gitdiff). Both commands take the same parameters, so for example to visually diff changes in a particular file you can type

gitdiff path/file.txt

Setup

Note that $GitInstall is used as a placeholder for the directory where Git is installed.

1. Create a new file, $GitInstall\cmd\gitdiff.cmd

   @echo off
   setlocal
   for /F "delims=" %%I in ("%~dp0..") do @set path=%%~fI\bin;%%~fI\mingw\bin;%PATH%
   if "%HOME%"=="" @set HOME=%USERPROFILE%
   set GIT_EXTERNAL_DIFF=git-diff-visual.cmd
   set GIT_PAGER=cat
   git diff %*
   endlocal
   

2. Create a new file, $GitInstall\bin\git-diff-visual.cmd (replacing [visual_diff_exe] placeholder with full path to the diff program of your choice)

   @echo off
   rem diff is called by git with 7 parameters:
   rem path old-file old-hex old-mode new-file new-hex new-mode
   echo Diffing "%5"
   "[visual_diff_exe]" "%2" "%5"
   exit 0
   

3. You're now done. Running gitdiff from within a Git repository should now invoke your visual diff program for every file that was changed.

Just in case commands in previous answers doesn't work, Try this: dat.dropna(subset=['x'], inplace = True)

This is all you need to know.

int state = 0;
while (state < 3)
{
    switch (state)
    {
        case 0:
            // Do State 0 Stuff
            if (should_go_to_next_state)
            {
                state++;
            }
            break;
        case 1:
            // Do State 1 Stuff    
            if (should_go_back) 
            {
                state--;
            }    
            else if (should_go_to_next_state) 
            {
                state++;
            }
            break;
        case 2:
            // Do State 2 Stuff    
            if (should_go_back_two) 
            {
                state -= 2;
            }    
            else if (should_go_to_next_state) 
            {
                state++;
            }
            break;
        default:
            break;
    }
}

This might be useful when you need individually annotate in different time (I mean, not in a single for loop)

ax = plt.gca()
ax.annotate('your_lable', (x,y)) 

where x and y are the your target coordinate and type is float/int.

I found the above answer giving an error with Oracle SQL, you also must use square brackets, below;

SQL> SELECT Q'[Paddy O'Reilly]' FROM DUAL;

Result: Paddy O'Reilly

My question was closed, I have no idea why . The accepted answer here is not the same as what I need.

This gives me the correct integer value for an IP..

public double IPAddressToNumber(string IPaddress)
{
    int i;
    string [] arrDec;
    double num = 0;
    if (IPaddress == "")
    {
        return 0;
    }
    else
    {
        arrDec = IPaddress.Split('.');
        for(i = arrDec.Length - 1; i >= 0 ; i = i -1)
            {
                num += ((int.Parse(arrDec[i])%256) * Math.Pow(256 ,(3 - i )));
            }
        return num;
    }
}

In C# 5 and earlier, to give auto implemented properties an initial value, you have to do it in a constructor.

Since C# 6.0, you can specify initial value in-line. The syntax is:

public int X { get; set; } = x; // C# 6 or higher

DefaultValueAttribute is intended to be used by the VS designer (or any other consumer) to specify a default value, not an initial value. (Even if in designed object, initial value is the default value).

At compile time DefaultValueAttribute will not impact the generated IL and it will not be read to initialize the property to that value (see DefaultValue attribute is not working with my Auto Property).

Example of attributes that impact the IL are ThreadStaticAttribute, CallerMemberNameAttribute, ...

To take 6footunder's comment and turn it into an answer, HttpContent is abstract so you need to use one of the derived classes:

Try this or purpose will solve with lesser no of steps

for (int i = 0; i < a.length; i++) 
{
    for (int k = i+1; k < a.length; k++) 
    {
        if (a[i] != a[k]) 
         {
            System.out.println(a[i]+"not the same with"+a[k]+"\n");
        }
    }
}

The other solution is correct in that it will get you a reference to the application's delegate, but this will not allow you to access any methods or variables added by your subclass of UIApplication, like your managed object context. To resolve this, simply downcast to "AppDelegate" or what ever your UIApplication subclass happens to be called. In Swift 3, 4 & 5, this is done as follows:

let appDelegate = UIApplication.shared.delegate as! AppDelegate
let aVariable = appDelegate.someVariable

USE TIMESTAMPDIFF MySQL function. For example, you can use:

SELECT TIMESTAMPDIFF(SECOND, '2012-06-06 13:13:55', '2012-06-06 15:20:18')

In your case, the third parameter of TIMSTAMPDIFF function would be the current login time (NOW()). Second parameter would be the last login time, which is already in the database.

this code probable help you .

<iframe src="" onload="this.width=screen.width;this.height=screen.height;">

To draw a centered text:

TextRenderer.DrawText(g, "my text", Font, Bounds, ForeColor, BackColor, 
  TextFormatFlags.HorizontalCenter | 
  TextFormatFlags.VerticalCenter |
  TextFormatFlags.GlyphOverhangPadding);

Determining optimal font size to fill an area is a bit more difficult. One working soultion I found is trial-and-error: start with a big font, then repeatedly measure the string and shrink the font until it fits.

Font FindBestFitFont(Graphics g, String text, Font font, 
  Size proposedSize, TextFormatFlags flags)
{ 
  // Compute actual size, shrink if needed
  while (true)
  {
    Size size = TextRenderer.MeasureText(g, text, font, proposedSize, flags);

    // It fits, back out
    if ( size.Height <= proposedSize.Height && 
         size.Width <= proposedSize.Width) { return font; }

    // Try a smaller font (90% of old size)
    Font oldFont = font;
    font = new Font(font.FontFamily, (float)(font.Size * .9)); 
    oldFont.Dispose();
  }
}

You'd use this as:

Font bestFitFont = FindBestFitFont(g, text, someBigFont, sizeToFitIn, flags);
// Then do your drawing using the bestFitFont
// Don't forget to dispose the font (if/when needed)

Well, I found a solution. It moves the mess, so that MVVM works.

First add this class:

public class ExtendedTreeView : TreeView
{
    public ExtendedTreeView()
        : base()
    {
        this.SelectedItemChanged += new RoutedPropertyChangedEventHandler<object>(___ICH);
    }

    void ___ICH(object sender, RoutedPropertyChangedEventArgs<object> e)
    {
        if (SelectedItem != null)
        {
            SetValue(SelectedItem_Property, SelectedItem);
        }
    }

    public object SelectedItem_
    {
        get { return (object)GetValue(SelectedItem_Property); }
        set { SetValue(SelectedItem_Property, value); }
    }
    public static readonly DependencyProperty SelectedItem_Property = DependencyProperty.Register("SelectedItem_", typeof(object), typeof(ExtendedTreeView), new UIPropertyMetadata(null));
}

and add this to your xaml:

 <local:ExtendedTreeView ItemsSource="{Binding Items}" SelectedItem_="{Binding Item, Mode=TwoWay}">
 .....
 </local:ExtendedTreeView>

This happens when response was delivered to client and again you are trying to give response. You have to check in your code that somewhere you are returning response to client again which causes this error. Check and return response once when you want to return.

You need a SMTP server to send your mail. If you have one available which does not require SMTP authentification (maybe your ISP's?) just edit the 'SMTP' ([mail function]) setting in your php.ini file.

If this is no option because your SMTP server requires authentification you won't be able to use the internal mail() function and have to use some 3rd party class which supports smtp auth. e.g. http://pear.php.net/package/Mail/

Hello everyone !! I created the solution to the issue at hand where Two UIInterface orientations are wanted using the UIIMagePicker.. In my ViewController where I handle the segue to the UIImagePickerController

**I use a..

-(void) editButtonPressed:(id)sender {
   BOOL editPressed = YES;
    NSUserDefaults *boolDefaults = [NSUserDefaults standardUserDefaults];
    [boolDefaults setBool:editPressed forKey:@"boolKey"];
    [boolDefaults synchronize];

    [self performSegueWithIdentifier:@"photoSegue" sender:nil]; 

}

**

Then in the AppDelegate Class I do the following.

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {

    BOOL appDelBool;
    NSUserDefaults *boolDefaults = [NSUserDefaults standardUserDefaults];
    appDelBool = [boolDefaults boolForKey:@"boolKey"];

       if (appDelBool == YES)
           return (UIInterfaceOrientationMaskPortrait);
        else
            return UIInterfaceOrientationMaskLandscapeLeft;
}

You should do:

#include<iostream>
using namespace std;
int main ()
{

    int sum = 0;
    int number;
    int numberitems;


    cout << "Enter number of items: \n";
    cin >> numberitems;

    for(int i=0;i<numberitems;i++)
    {
        cout << "Enter number <<i<<":" \n";
        cin >> number; sum+=number;
    }
    cout<<"sum is: "<< sum<<endl;
}

And with a while statement

#include <iostream>
using namespace std;
int main ()
{
    int sum = 0;
    int number;
    int numberitems;
    cin>>numberitems;

    cout << "Enter number: \n";

    while (count <=numberitems)
    {
        cin >> number;
        sum+=number;
    }
    cout << sum << endl;
}

This will work too!

foreach($data as &$value) {
  $value['transaction_date'] = date('d/m/Y', $value['transaction_date']);
}

Yay for alternatives!

Hazar is right with his \t. Here's the full list of escape characters for C#:

\' for a single quote.

\" for a double quote.

\\ for a backslash.

\0 for a null character.

\a for an alert character.

\b for a backspace.

\f for a form feed.

\n for a new line.

\r for a carriage return.

\t for a horizontal tab.

\v for a vertical tab.

\uxxxx for a unicode character hex value (e.g. \u0020).

\x is the same as \u, but you don't need leading zeroes (e.g. \x20).

\Uxxxxxxxx for a unicode character hex value (longer form needed for generating surrogates).

If you use Sqlite's REGEXP support ( see the answer at Problem with regexp python and sqlite for how to do that ) , then you can do it easily in one clause:

SELECT word FROM table WHERE word NOT REGEXP '[abc]';

I have had this issue before, you need more than the standard 755 or 644 permission to store the $_SESSION information. You need to be able to write to that file as that is how it remembers.

JFrame.setVisible(true);

You can either use setVisible(false) or dispose() method to disappear current form.

You can use the built-in Dir function or the FileSystemObject.

• Dir Function: VBA: Dir Function

• FileSystemObject: VBA: FileSystemObject - Files Collection

They each have their own strengths and weaknesses.

Dir Function

The Dir Function is a built-in, lightweight method to get a list of files. The benefits for using it are:

• Easy to Use
• Good performance (it's fast)
• Wildcard support

The trick is to understand the difference between calling it with or without a parameter. Here is a very simple example to demonstrate:

Public Sub ListFilesDir(ByVal sPath As String, Optional ByVal sFilter As String)

    Dim sFile As String

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file name
    sFile = Dir(sPath & sFilter)

   'call it again until there are no more files
    Do Until sFile = ""

        Debug.Print sFile

        'subsequent calls without param return next file name
        sFile = Dir

    Loop

End Sub

If you alter any of the files inside the loop, you will get unpredictable results. It is better to read all the names into an array of strings before doing any operations on the files. Here is an example which builds on the previous one. This is a Function that returns a String Array:

Public Function GetFilesDir(ByVal sPath As String, _
    Optional ByVal sFilter As String) As String()

    'dynamic array for names
    Dim aFileNames() As String
    ReDim aFileNames(0)

    Dim sFile As String
    Dim nCounter As Long

    If Right(sPath, 1) <> "\" Then
        sPath = sPath & "\"
    End If

    If sFilter = "" Then
        sFilter = "*.*"
    End If

    'call with path "initializes" the dir function and returns the first file
    sFile = Dir(sPath & sFilter)

    'call it until there is no filename returned
    Do While sFile <> ""

        'store the file name in the array
        aFileNames(nCounter) = sFile

        'subsequent calls without param return next file
        sFile = Dir

        'make sure your array is large enough for another
        nCounter = nCounter + 1
        If nCounter > UBound(aFileNames) Then
            'preserve the values and grow by reasonable amount for performance
            ReDim Preserve aFileNames(UBound(aFileNames) + 255)
        End If

    Loop

    'truncate the array to correct size
    If nCounter < UBound(aFileNames) Then
        ReDim Preserve aFileNames(0 To nCounter - 1)
    End If

    'return the array of file names
    GetFilesDir = aFileNames()

End Function

File System Object

The File System Object is a library for IO operations which supports an object-model for manipulating files. Pros for this approach:

• Intellisense
• Robust object-model

You can add a reference to to "Windows Script Host Object Model" (or "Windows Scripting Runtime") and declare your objects like so:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As FileSystemObject
    Dim oFolder As Folder
    Dim oFile As File

    Set oFSO = New FileSystemObject
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

If you don't want intellisense you can do like so without setting a reference:

Public Sub ListFilesFSO(ByVal sPath As String)

    Dim oFSO As Object
    Dim oFolder As Object
    Dim oFile As Object

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oFolder = oFSO.GetFolder(sPath)
    For Each oFile In oFolder.Files
        Debug.Print oFile.Name
    Next 'oFile

    Set oFile = Nothing
    Set oFolder = Nothing
    Set oFSO = Nothing

End Sub

I had a similar issue on 16.04 VPS Digital Ocean. If you are changing crontabs, make sure to run

sudo service cron restart 

After some limited testing with Spring 3.2, it seems one can use a SpEL list: {..., ..., ...}. This can also include null values. Spring passes the list as the key to the actual cache implementation. When using Ehcache, such will at some point invoke List#hashCode(), which takes all its items into account. (I am not sure if Ehcache only relies on the hash code.)

I use this for a shared cache, in which I include the method name in the key as well, which the Spring default key generator does not include. This way I can easily wipe the (single) cache, without (too much...) risking matching keys for different methods. Like:

@Cacheable(value="bookCache", 
  key="{ #root.methodName, #isbn?.id, #checkWarehouse }")
public Book findBook(ISBN isbn, boolean checkWarehouse) 
...

@Cacheable(value="bookCache", 
  key="{ #root.methodName, #asin, #checkWarehouse }")
public Book findBookByAmazonId(String asin, boolean checkWarehouse)
...

Of course, if many methods need this and you're always using all parameters for your key, then one can also define a custom key generator that includes the class and method name:

<cache:annotation-driven mode="..." key-generator="cacheKeyGenerator" />
<bean id="cacheKeyGenerator" class="net.example.cache.CacheKeyGenerator" />

...with:

public class CacheKeyGenerator 
  implements org.springframework.cache.interceptor.KeyGenerator {

    @Override
    public Object generate(final Object target, final Method method, 
      final Object... params) {

        final List<Object> key = new ArrayList<>();
        key.add(method.getDeclaringClass().getName());
        key.add(method.getName());

        for (final Object o : params) {
            key.add(o);
        }
        return key;
    }
}

You are not providing a lot of information, but assuming you want to open just any file on your computer with the application that is specified for the default handler for that filetype, you can use something like this:

var fileToOpen = "SomeFilePathHere";
var process = new Process();
process.StartInfo = new ProcessStartInfo()
{
    UseShellExecute = true,
    FileName = fileToOpen
};

process.Start();
process.WaitForExit();

The UseShellExecute parameter tells Windows to use the default program for the type of file you are opening.

The WaitForExit will cause your application to wait until the application you luanched has been closed.

After perusing your previous questions I eventually determined you are probably on SQL Server 2005. For US format you would use style 101

select Subject, 
       CONVERT(varchar,DeliveryDate,101) as DeliveryDate
from Email_Administration 
where MerchantId =@MerchantID 

Not currently. It will be available in CSS 3, but it will take some time until it's implemented in most browsers.

Try gcc -c -I/home/me/development/skia sample.c.

if you are a vim user, you can install tig (apt-get install tig), and use /, same command to search on vim

The correct way to compare maps for value-equality is to:

1. Check that the maps are the same size(!)
2. Get the set of keys from one map
3. For each key from that set you retrieved, check that the value retrieved from each map for that key is the same (if the key is absent from one map, that's a total failure of equality)

In other words (minus error handling):

boolean equalMaps(Map<K,V>m1, Map<K,V>m2) {
   if (m1.size() != m2.size())
      return false;
   for (K key: m1.keySet())
      if (!m1.get(key).equals(m2.get(key)))
         return false;
   return true;
}

For example, to set the background color to orange:

<meta name="theme-color" content="#db5945">

In addition, Chrome will show beautiful high-res favicons when they’re provided. Chrome for Android picks the highest res icon that you provide, and we recommend providing a 192×192px PNG file. For example:

<link rel="icon" sizes="192x192" href="nice-highres.png">

By the way, you can use next code in you event handler:

switch(e.EventType)
{
  case SerialData.Chars:
  {
    // means you receives something
    break;
  }
  case SerialData.Eof:
  {
    // means receiving ended
    break;
  }
}

$('#myModal').modal('hide') should do it

According to RFC2965 3.3.1 (which might or might not be followed by browsers), unless the port is explicitly specified via the port parameter of the Set-Cookie header, cookies might or might not be sent to any port.

Google's Browser Security Handbook says: by default, cookie scope is limited to all URLs on the current host name - and not bound to port or protocol information. and some lines later There is no way to limit cookies to a single DNS name only [...] likewise, there is no way to limit them to a specific port. (Also, keep in mind, that IE does not factor port numbers into its same-origin policy at all.)

So it does not seem to be safe to rely on any well-defined behavior here.

Microsoft provides a walkthrough for creating a Windows Explorer style interface in C#.

There are also several examples on Code Project and other sites. Immediate examples are Explorer Tree, My Explorer, File Browser and Advanced File Explorer but there are others. Explorer Tree seems to look the best from the brief glance I took.

I used the search term windows explorer tree view C# in Google to find these links.

You can use the Apache Commons StringUtils.substring(String str, int start, int end) static method, which is also null safe.

See: http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/StringUtils.html#substring%28java.lang.String,%20int,%20int%29

and http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/src-html/org/apache/commons/lang/StringUtils.html#line.1961

The accepted answer (its image) is wrong, at least now in QT5. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow instead of centralWidget). Also note that you must have at least one QObject created beneath it for this to work. Do this and your ui will become responsive to window resizing.

You can solve it using dictionary

to_modify = [5,4,3,2,1,0]
indexes = [0,1,3,5]
replacements = [0,0,0,0]

dic = {}
for i in range(len(indexes)):
    dic[indexes[i]]=replacements[i]
print(dic)

for index, item in enumerate(to_modify):
    for i in indexes:
        to_modify[i]=dic[i]
print(to_modify)

The output will be

{0: 0, 1: 0, 3: 0, 5: 0}
[0, 0, 3, 0, 1, 0]

You can check out the CXF. You can visit the JAX-RS Article here

Calling is as simple as this (quote):

BookStore store = JAXRSClientFactory.create("http://bookstore.com", BookStore.class);
// (1) remote GET call to http://bookstore.com/bookstore
Books books = store.getAllBooks();
// (2) no remote call
BookResource subresource = store.getBookSubresource(1);
// {3} remote GET call to http://bookstore.com/bookstore/1
Book b = subresource.getDescription();

You can create an object of key/value pairs and jQuery will do the rest for you:

$.ajax({
    ...
    data : { foo : 'bar', bar : 'foo' },
    ...
});

This way the data will be properly encoded automatically. If you do want to concoct you own string then make sure to use encodeURIComponent(): https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/encodeURIComponent

Your current code is not working because the string is not concocted properly:

'id='+ id  & 'name='+ name

should be:

'id='+ encodeURIComponent(id) + '&name='+ encodeURIComponent(name)

I know I'm a little late tothe party but thisworks pretty neat (our professor gave it to us)

public static byte[] asBytes (String s) {                   
           String tmp;
           byte[] b = new byte[s.length() / 2];
           int i;
           for (i = 0; i < s.length() / 2; i++) {
             tmp = s.substring(i * 2, i * 2 + 2);
             b[i] = (byte)(Integer.parseInt(tmp, 16) & 0xff);
           }
           return b;                                            //return bytes
    }

I think that you should make the reference to your config file

26399:C 16 Jan 08:51:13.413 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

you can try to start your redis server like

./redis-server /path/to/redis-stable/redis.conf

If the dataframe has multiple types of columns, some characters, some numeric try the following to convert just the columns that contain numeric values to numeric:

for (i in 1:length(data[1,])){
  if(length(as.numeric(data[,i][!is.na(data[,i])])[!is.na(as.numeric(data[,i][!is.na(data[,i])]))])==0){}
  else {
    data[,i]<-as.numeric(data[,i])
  }
}

Just checked IE 7, Firefox 3.6.8 Mac, Firefox 3.6.8 Windows, and Safari:

word-wrap: break-word;

works for long links inside of a div with a set width and no overflow declared in the css:

#consumeralerts_leftcol{
    float:left;
    width: 250px;
    margin-bottom:10px;
    word-wrap: break-word;
}

I don't see any incompatibility issues

If you're talking about bitwise operators, then you're after:

~ Not
^ XOR
| Or
& And

Otherwise, binary numbers work exactly the same as decimal numbers, because numbers are numbers, no matter how you look at them. The only difference between decimal and binary is how we represent that data when we are looking at it.

Its worth mentioning that the default for an 'Any CPU' compile now checks the 'Prefer 32bit' check box. Being set to AnyCPU, on a 64bit OS with 16gb of RAM can still hit an out of memory exception at 2gb if this is checked.
