To configure a message converter in plain spring-web, in this case to enable the Java 8 JSR-310 JavaTimeModule, you first need to implement WebMvcConfigurer in your @Configuration class and then override the configureMessageConverters method:

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    ObjectMapper objectMapper = Jackson2ObjectMapperBuilder.json().modules(new JavaTimeModule(), new Jdk8Module()).build()
            .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
    converters.add(new MappingJackson2HttpMessageConverter(objectMapper));
}

Like this you can register any custom defined ObjectMapper in a Java-based Spring configuration.

Could use IgnoreAttribute on the property which needs to be ignored

Suppose originally there were 3 commits, A,B,C:

Then developer Dan created commit D, and developer Ed created commit E:

Obviously, this conflict should be resolved somehow. For this, there are 2 ways:

MERGE:

Both commits D and E are still here, but we create merge commit M that inherits changes from both D and E. However, this creates diamond shape, which many people find very confusing.

REBASE:

We create commit R, which actual file content is identical to that of merge commit M above. But, we get rid of commit E, like it never existed (denoted by dots - vanishing line). Because of this obliteration, E should be local to developer Ed and should have never been pushed to any other repository. Advantage of rebase is that diamond shape is avoided, and history stays nice straight line - most developers love that!

You also have the Trim, TrimEnd and TrimStart methods of the System.String class. The trim method will strip whitespace (with a couple of Unicode quirks) from the leading and trailing portion of the string while allowing you to optionally specify the characters to remove.

#Note there are spaces at the beginning and end
Write-Host " ! This is a test string !%^ "
 ! This is a test string !%^
#Strips standard whitespace
Write-Host " ! This is a test string !%^ ".Trim()
! This is a test string !%^
#Strips the characters I specified
Write-Host " ! This is a test string !%^ ".Trim('!',' ')
This is a test string !%^
#Now removing ^ as well
Write-Host " ! This is a test string !%^ ".Trim('!',' ','^')
This is a test string !%
Write-Host " ! This is a test string !%^ ".Trim('!',' ','^','%')
This is a test string
#Powershell even casts strings to character arrays for you
Write-Host " ! This is a test string !%^ ".Trim('! ^%')
This is a test string

TrimStart and TrimEnd work the same way just only trimming the start or end of the string.

If you don't want use jQuery:

function check_pass() {
    if (document.getElementById('password').value ==
            document.getElementById('confirm_password').value) {
        document.getElementById('submit').disabled = false;
    } else {
        document.getElementById('submit').disabled = true;
    }
}

<input type="password" name="password" id="password" onchange='check_pass();'/>
<input type="password" name="confirm_password" id="confirm_password" onchange='check_pass();'/>
<input type="submit" name="submit"  value="registration"  id="submit" disabled/>

Try --allow-unrelated-histories

Like max630 commented, or as explained here Git refusing to merge unrelated histories

date must be insert with two apostrophes' As example if the date is 2018/10/20. It can insert from these query

Query -

insert into run(id,name,dob)values(&id,'&name','2018-10-20')

This is the best way.

1. First put your cursor on the member and click F2.

2. Then type the new name and hit the Enter key. This will rename all of the occurrences in every file in your project.

This is ideal for when you want to rename across multiple files. For example, you may want to rename a publicly accessible function on an Angular service and have everywhere that uses it get updated.

For more great tools I highly recommend: https://johnpapa.net/refactoring-with-visual-studio-code/

Simpler way:

if grep "$filename" my_list.txt > /dev/null
then
   ... found
else
   ... not found
fi

Tip: send to /dev/null if you want command's exit status, but not outputs.

Using extended slice syntax

word = input ("Type a word which you want to reverse: ")
def reverse(word):
  word = word[::-1]
  return word
print (reverse(word))

Another alternative is to re-run the JRE setup. It typically installs a default JRE by placing java.exe, javaw.exe, etc. in your system folder. That would place the executables in your path, which should be sufficient, based on the note in the error message that it searched your path for javaw.exe

Both rebase (and cherry-pick) and merge have their advantages and disadvantages. I argue for merge here, but it's worth understanding both. (Look here for an alternate, well-argued answer enumerating cases where rebase is preferred.)

merge is preferred over cherry-pick and rebase for a couple of reasons.

1. Robustness. The SHA1 identifier of a commit identifies it not just in and of itself but also in relation to all other commits that precede it. This offers you a guarantee that the state of the repository at a given SHA1 is identical across all clones. There is (in theory) no chance that someone has done what looks like the same change but is actually corrupting or hijacking your repository. You can cherry-pick in individual changes and they are likely the same, but you have no guarantee. (As a minor secondary issue the new cherry-picked commits will take up extra space if someone else cherry-picks in the same commit again, as they will both be present in the history even if your working copies end up being identical.)
2. Ease of use. People tend to understand the merge workflow fairly easily. rebase tends to be considered more advanced. It's best to understand both, but people who do not want to be experts in version control (which in my experience has included many colleagues who are damn good at what they do, but don't want to spend the extra time) have an easier time just merging.

Even with a merge-heavy workflow rebase and cherry-pick are still useful for particular cases:

1. One downside to merge is cluttered history. rebase prevents a long series of commits from being scattered about in your history, as they would be if you periodically merged in others' changes. That is in fact its main purpose as I use it. What you want to be very careful of, is never to rebase code that you have shared with other repositories. Once a commit is pushed someone else might have committed on top of it, and rebasing will at best cause the kind of duplication discussed above. At worst you can end up with a very confused repository and subtle errors it will take you a long time to ferret out.
2. cherry-pick is useful for sampling out a small subset of changes from a topic branch you've basically decided to discard, but realized there are a couple of useful pieces on.

As for preferring merging many changes over one: it's just a lot simpler. It can get very tedious to do merges of individual changesets once you start having a lot of them. The merge resolution in git (and in Mercurial, and in Bazaar) is very very good. You won't run into major problems merging even long branches most of the time. I generally merge everything all at once and only if I get a large number of conflicts do I back up and re-run the merge piecemeal. Even then I do it in large chunks. As a very real example I had a colleague who had 3 months worth of changes to merge, and got some 9000 conflicts in 250000 line code-base. What we did to fix is do the merge one month's worth at a time: conflicts do not build up linearly, and doing it in pieces results in far fewer than 9000 conflicts. It was still a lot of work, but not as much as trying to do it one commit at a time.

Now in 2017 with ASP.Net Core you can do it as explained here.

The Microsoft.AspNetCore.Session package provides middleware for managing session state.

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
  // Adds a default in-memory implementation of IDistributedCache.
    services.AddDistributedMemoryCache();

    services.AddSession(options =>
    {
        // Set a short timeout for easy testing.
        options.IdleTimeout = TimeSpan.FromSeconds(10);
        options.Cookie.HttpOnly = true;
    });
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseSession();
}

You seem to look for the input attribute value, "the initial value of the control"?

<input type="text" value="Morlodenhof 7" />

https://developer.mozilla.org/de/docs/Web/HTML/Element/Input#attr-value

Just Additional Info which took me long time to find.what if you were using the field name and not id for identifying the form field. You do it like this:

For radio button:

var inp= $('input:radio[name=PatientPreviouslyReceivedDrug]:checked').val();

For textbox:

var txt=$('input:text[name=DrugDurationLength]').val();

You can update progress bar only from ProgressChanged or RunWorkerCompleted event handlers as these are synchronized with the UI thread.

The basic idea is. Thread.Sleep just simulates some work here. Replace it with your real routing call.

public Form1()
{
    InitializeComponent();

    backgroundWorker1.DoWork += backgroundWorker1_DoWork;
    backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
    backgroundWorker1.WorkerReportsProgress = true;
}

private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000);
        backgroundWorker1.ReportProgress(i);
    }
}

private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

POSIX 7 on echo

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html

-e is not defined and backslashes are implementation defined:

If the first operand is -n, or if any of the operands contain a <backslash> character, the results are implementation-defined.

unless you have an optional XSI extension.

So I recommend that you should use printf instead, which is well specified:

format operand shall be used as the format string described in XBD File Format Notation [...]

the File Format Notation:

\n <newline> Move the printing position to the start of the next line.

Also keep in mind that Ubuntu 15.10 and most distros implement echo both as:

• a Bash built-in: help echo
• a standalone executable: which echo

which can lead to some confusion.

try this

    $("#mprDetailDataTable tr:gt(0)").each(function () {
        var this_row = $(this);
        var productId = $.trim(this_row.find('td:eq(0)').html());//td:eq(0) means first td of this row
        var product = $.trim(this_row.find('td:eq(1)').html())
        var Quantity = $.trim(this_row.find('td:eq(2)').html())
    });

You get a SIGABRT error whenever you have a disconnected outlet. Click on your view controller in the storyboard and go to connections in the side panel (the arrow symbol). See if you have an extra outlet there, a duplicate, or an extra one that's not connected. If it's not that then maybe you haven't connected your outlets to your code correctly.

Just remember that SIGABRT happens when you are trying to call an outlet (button, view, textfield, etc) that isn't there.

The solution in this gist did it for me

brew uninstall --ignore-dependencies node icu4c
brew install node

There is an easier way where you don't have to type any code (Ideal for Testing or One-time updates):

Step 1

• Right click on table in the explorer and select "Edit top 100 rows";

Step 2

• Then you can select the rows that you want (Ctrl + Click or Ctrl + A), and Right click and Copy (Note: If you want to add a "where" condition, then Right Click on Grid -> Pane -> SQL Now you can edit Query and add WHERE condition, then Right Click again -> Execute SQL, your required rows will be available to select on bottom)

Step 3

• Follow Step 1 for the target table.

Step 4

• Now go to the end of the grid and the last row will have an asterix (*) in first column (This row is to add new entry). Click on that to select that entire row and then PASTE (Ctrl + V). The cell might have a Red Asterix (indicating that it is not saved)

Step 5

• Click on any other row to trigger the insert statement (the Red Asterix will disappear)

Note - 1: If the columns are not in the correct order as in Target table, you can always follow Step 2, and Select the Columns in the same order as in the Target table

Note - 2 - If you have Identity columns then execute SET IDENTITY_INSERT sometableWithIdentity ON and then follow above steps, and in the end execute SET IDENTITY_INSERT sometableWithIdentity OFF

1) You can use an Align widget, with FractionalOffset.bottomCenter.

2) You can also set left: 0.0 and right: 0.0 in the Positioned.

The beauty of C++, like C, is that the sized of these things are implementation-defined, so there's no correct answer without your specifying the compiler you're using. Are those two the same? Yes. "long long" is a synonym for "long long int", for any compiler that will accept both.

process.terminate() doesn't work when using shell=True. This answer will help you.

You need to use absolutely-positioned CSS over a relatively-positioned img tag. The article Text Blocks Over Image gives a step-by-step example for placing text over an image.

Look at using the beautiful soup html parsing library.

http://www.crummy.com/software/BeautifulSoup/

You will do something like this:

import BeautifulSoup
soup = BeautifulSoup.BeautifulSoup(html)
for link in soup.findAll("a"):
    print link.get("href")

From the Javadocs for setDisplayOrientation(int) (Requires API level 9):

 public static void setCameraDisplayOrientation(Activity activity,
         int cameraId, android.hardware.Camera camera) {
     android.hardware.Camera.CameraInfo info =
             new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     int rotation = activity.getWindowManager().getDefaultDisplay()
             .getRotation();
     int degrees = 0;
     switch (rotation) {
         case Surface.ROTATION_0: degrees = 0; break;
         case Surface.ROTATION_90: degrees = 90; break;
         case Surface.ROTATION_180: degrees = 180; break;
         case Surface.ROTATION_270: degrees = 270; break;
     }

     int result;
     if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
         result = (info.orientation + degrees) % 360;
         result = (360 - result) % 360;  // compensate the mirror
     } else {  // back-facing
         result = (info.orientation - degrees + 360) % 360;
     }
     camera.setDisplayOrientation(result);
 }

Given a list List<Object> which you want to iterate over, the easy-peasy way is:

while (!list.isEmpty()){
   Object obj = list.get(0);

   // do whatever you need to
   // possibly list.add(new Object obj1);

   list.remove(0);
}

So, you iterate through a list, always taking the first element and then removing it. This way you can append new elements to the list while iterating.

var array = [1,2,3,4];
var anotherOne = [2,4];
var filteredArray = array.filter(myCallBack);

function myCallBack(el){
  return anotherOne.indexOf(el) < 0;
}

In the callback, you check if each value of array is in anotherOne

https://jsfiddle.net/0tsyc1sx/

If you are using lodash.js, use _.difference

filteredArray = _.difference(array, anotherOne);

Demo

If you have an array of objects :

var array = [{id :1, name :"test1"},{id :2, name :"test2"},{id :3, name :"test3"},{id :4, name :"test4"}];

var anotherOne = [{id :2, name :"test2"}, {id :4, name :"test4"}];

var filteredArray  = array.filter(function(array_el){
   return anotherOne.filter(function(anotherOne_el){
      return anotherOne_el.id == array_el.id;
   }).length == 0
});

This is built on some of the previous answers and comments. The following covers all the edge cases and fairly concise as well:

const isNumRegEx = /^-?(\d*\.)?\d+$/;

function isNumeric(n, allowScientificNotation = false) {
    return allowScientificNotation ? 
                !Number.isNaN(parseFloat(n)) && Number.isFinite(n) :
                isNumRegEx.test(n);
}

Since set_value has been deprecated since version 0.21.0, you should now use at. It can insert a list into a cell without raising a ValueError as loc does. I think this is because at always refers to a single value, while loc can refer to values as well as rows and columns.

df = pd.DataFrame(data={'A': [1, 2, 3], 'B': ['x', 'y', 'z']})

df.at[1, 'B'] = ['m', 'n']

df =
    A   B
0   1   x
1   2   [m, n]
2   3   z

You also need to make sure the column you are inserting into has dtype=object. For example

>>> df = pd.DataFrame(data={'A': [1, 2, 3], 'B': [1,2,3]})
>>> df.dtypes
A    int64
B    int64
dtype: object

>>> df.at[1, 'B'] = [1, 2, 3]
ValueError: setting an array element with a sequence

>>> df['B'] = df['B'].astype('object')
>>> df.at[1, 'B'] = [1, 2, 3]
>>> df
   A          B
0  1          1
1  2  [1, 2, 3]
2  3          3

For Python 2.7

Add the environment variable PYTHONWARNINGS as key and the corresponding value to be ignored like:

os.environ['PYTHONWARNINGS']="ignore:Unverified HTTPS request"

You should not execute resource intensive tasks in the main thread. It will make the UI unresponsive and you will get an ANR. It seems like you will be doing resource intensive stuff and want the user to see the ProgressDialog. You can take a look at http://developer.android.com/reference/android/os/AsyncTask.html to do resource intensive tasks. It also shows you how to use a ProgressDialog.

Use npm to uninstall. Just running sudo npm uninstall npm -g removes all the files. To get rid of the extraneous stuff like bash pathnames run this (from nicerobot's answer):

sudo rm -rf /usr/local/lib/node \ /usr/local/lib/node_modules \ /var/db/receipts/org.nodejs.*

Can do a foreachloop too..

$collection = Model::get();

foreach($collection as $c) {

$c->delete();

}

select[value="value"]{
   background-color: red;
   padding: 3px;
   font-weight:bold;
}

Easy, simply wrap a MemoryStream around it:

Stream stream = new MemoryStream(buffer);

I had the same problem in production (development everything worked), in my case the DB server is not on the same machine as the app, so finally what worked is just to migrate by writing:

bundle exec rake db:migrate RAILS_ENV=production

and then restart the server and everything worked.

Here is a shorter bit of code that reenables scroll bars across your entire website. I'm not sure if it's much different than the current most popular answer but here it is:

The one-liner that Andre Miller posted above works except for recent versions of sed when the input file ends with a blank line and no chars. On my Mac my CPU just spins.

Infinite loop if last line is blank and has no chars:

sed '$!N; /^\(.*\)\n\1$/!P; D'

Doesn't hang, but you lose the last line

sed '$d;N; /^\(.*\)\n\1$/!P; D'

The explanation is at the very end of the sed FAQ:

The GNU sed maintainer felt that despite the portability problems
this would cause, changing the N command to print (rather than
delete) the pattern space was more consistent with one's intuitions
about how a command to "append the Next line" ought to behave.
Another fact favoring the change was that "{N;command;}" will
delete the last line if the file has an odd number of lines, but
print the last line if the file has an even number of lines.

To convert scripts which used the former behavior of N (deleting
the pattern space upon reaching the EOF) to scripts compatible with
all versions of sed, change a lone "N;" to "$d;N;".

You can do this easily by adding a Timer to your form (from the designer) and setting it's Tick-function to run your isonline-function.

The keycodes returned by waitKey seem platform dependent. However, it may be very educative, to see what the keys return (and by the way, on my platform, Esc does not return 27...)

The integers thay Abid's answer lists are mosty useless to the human mind (unless you're a prodigy savant...). However, if you examine them in hex, or take a look at the Least Significant Byte, you may notice patterns...

My script for examining the return values from waitKey is below:

#!/usr/bin/env python

import cv2
import sys

cv2.imshow(sys.argv[1], cv2.imread(sys.argv[1]))
res = cv2.waitKey(0)
print('You pressed %d (0x%x), LSB: %d (%s)' % (res, res, res % 256,
    repr(chr(res%256)) if res%256 < 128 else '?'))

You can use it as a minimal, command-line image viewer.

Some results, which I got:

• q letter:

  You pressed 1048689 (0x100071), LSB: 113 ('q')

• Escape key (traditionally, ASCII 27):

  You pressed 1048603 (0x10001b), LSB: 27 ('\x1b')

• Space:

  You pressed 1048608 (0x100020), LSB: 32 (' ')

This list could go on, however you see the way to go, when you get 'strange' results.

BTW, if you want to put it in a loop, you can just waitKey(0) (wait forever), instead of ignoring the -1 return value.

EDIT: There's more to these high bits than meets the eye - please see Andrew C's answer (hint: it has to do with keyboard modifiers like all the "Locks" e.g. NumLock).

My recent experience shows however, that there is a platform dependence - e.g. OpenCV 4.1.0 from Anaconda on Python 3.6 on Windows doesn't produce these bits, and for some (important) keys is returns 0 from waitKey() (arrows, Home, End, PageDn, PageUp, even Del and Ins). At least Backspace returns 8 (but... why not Del?).

So, for a cross platform UI you're probably restricted to W, A, S, D, letters, digits, Esc, Space and Backspace ;)

Indeed SET TEST_VARIABLE=value works for current process only, so SETX is required. A quick example for permanently storing an environment variable at user level.

1. In cmd, SETX TEST_VARIABLE etc. Not applied yet (echo %TEST_VARIABLE% shows %TEST_VARIABLE%,
2. Quick check: open cmd, echo %TEST_VARIABLE% shows etc.
3. GUI check: System Properties -> Advanced -> Environment variables -> User variables for -> you should see Varible TEST_VARIABLE with value etc.

awk works well if you your server has it

var="text,text,text,text" 
num=$(echo "${var}" | awk -F, '{print NF-1}')
echo "${num}"

If the user doesn't exist, getent will return an error.

Here's a small shell function that doesn't ignore the exit code of getent:

get_home() {
  local result; result="$(getent passwd "$1")" || return
  echo $result | cut -d : -f 6
}

Here's a usage example:

da_home="$(get_home missing_user)" || {
  echo 'User does NOT exist!'; exit 1
}

# Now do something with $da_home
echo "Home directory is: '$da_home'"

You can call a service from your controller that returns a promise and then use it in your controller. And further use $emit or $broadcast to inform other controllers about it. In my case, I had to make http calls through my service, so I did something like this :

function ParentController($scope, testService) {
    testService.getList()
        .then(function(data) {
            $scope.list = testService.list;
        })
        .finally(function() {
            $scope.$emit('listFetched');
        })


    function ChildController($scope, testService) {
        $scope.$on('listFetched', function(event, data) {
            // use the data accordingly
        })
    }

and my service looks like this

    app.service('testService', ['$http', function($http) {

        this.list = [];

        this.getList = function() {
            return $http.get(someUrl)
                .then(function(response) {
                    if (typeof response.data === 'object') {
                        list = response.data.results;

                        return response.data;
                    } else {
                        // invalid response
                        return $q.reject(response.data);
                    }

                }, function(response) {
                    // something went wrong
                    return $q.reject(response.data);
                });

        }

    }])

        double a,b;
        Console.WriteLine("istenen sayiyi sonuna .00 koyarak yaz");
        try
        {
            a = Convert.ToDouble(Console.ReadLine());
            b = a * Math.PI;
            Console.WriteLine("Sonuç " + b); 
        }
        catch (Exception)
        {
            Console.WriteLine("dönüstürme hatasi");
            throw;
        }

Because you are outputting to the browser, you have to use <br/>. Otherwise there is \n and \r or both combined.

The Python docs for hash() state:

Hash values are integers. They are used to quickly compare dictionary keys during a dictionary lookup.

Python dictionaries are implemented as hash tables. So any time you use a dictionary, hash() is called on the keys that you pass in for assignment, or look-up.

Additionally, the docs for the dict type state:

Values that are not hashable, that is, values containing lists, dictionaries or other mutable types (that are compared by value rather than by object identity) may not be used as keys.

Like this:

$result1 = mysql_query($query1);
$result2 = mysql_query($query2);

// do something with the 2 result sets...

if ($result1)
    mysql_free_result($result1);

if ($result2)
    mysql_free_result($result2);

You can do the same with .ix, like this:

In [1]: df = pd.DataFrame(np.random.randn(5,4), columns=list('abcd'))

After the extra information, the following will return all columns - where some condition is met - with halved values:

>> condition = df.a > 0
>> df[condition][[i for i in df.columns.values if i not in ['a']]].apply(lambda x: x/2)

I hope this helps!

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

Why is $observe different than $watch?

The watchExpression is evaluated and compared to the previous value each digest() cycle, if there's a change in the watchExpression value, the watch function is called.

$observe is specific to watching for interpolated values. If a directive's attribute value is interpolated, eg dir-attr="{{ scopeVar }}", the observe function will only be called when the interpolated value is set (and therefore when $digest has already determined updates need to be made). Basically there's already a watcher for the interpolation, and the $observe function piggybacks off that.

See $observe & $set in compile.js

New .NET 5 Solution:

In .NET 5, a new class has been introduced called JsonContent, which derives from HttpContent. See in Microsoft docs

This class has a static method called Create(), which takes an object as a parameter.

Usage:

var myObject = new
{
    foo = "Hello",
    bar = "World",
};

JsonContent content = JsonContent.Create(myObject);

HttpResponseMessage response = await _httpClient.PostAsync("https://...", content);

There are different points of view. One is they are the same. But in practice, we need to differentiate formal parameters (declarations in the method's header) and actual parameters (values passed at the point of invocation). While phrases "formal parameter" and "actual parameter" are common, "formal argument" and "actual argument" are not used. This is because "argument" is used mainly to denote "actual parameter". As a result, some people insist that "parameter" can denote only "formal parameter".

I know I'm 4 years late but my answer is for anyone who may not have figured it out. I'm using a Samsung Galaxy S6, what worked for me was:

1. Disable USB debugging

2. Disable Developer mode

3. Unplug the device from the USB cable

4. Re-enable Developer mode

5. Re-enable USB debugging

6. Reconnect the USB cable to your device

It is important you do it in this order as it didn't work until it was done in this order.

to server html pages through routing, I have done this.

var hbs = require('express-hbs');
app.engine('hbs', hbs.express4({
  partialsDir: __dirname + '/views/partials'
}));
app.set('views', __dirname + '/views');
app.set('view engine', 'hbs');

and renamed my .html files to .hbs files - handlebars support plain html

The only working solution for me, was to define the data object in the geom_line instead of the base object, ggplot.

Like this:

ggplot() + 
geom_line(data=Data1, aes(x=A, y=B), color='green') + 
geom_line(data=Data2, aes(x=C, y=D), color='red')

instead of

ggplot(data=Data1, aes(x=A, y=B), color='green') + 
geom_line() + 
geom_line(data=Data2, aes(x=C, y=D), color='red')

Not tested, but the closer you can get seems to be is with AutoCompleteTextView. You can write an adapter wich ignores the filter functions. Something like:

class UnconditionalArrayAdapter<T> extends ArrayAdapter<T> {
    final List<T> items;
    public UnconditionalArrayAdapter(Context context, int textViewResourceId, List<T> items) {
        super(context, textViewResourceId, items);
        this.items = items;
    }

    public Filter getFilter() {
        return new NullFilter();
    }

    class NullFilter extends Filter {
        protected Filter.FilterResults performFiltering(CharSequence constraint) {
            final FilterResults results = new FilterResults();
            results.values = items;
            return results;
        }

        protected void publishResults(CharSequence constraint, Filter.FilterResults results) {
            items.clear(); // `items` must be final, thus we need to copy the elements by hand.
            for (Object item : (List) results.values) {
                items.add((String) item);
            }
            if (results.count > 0) {
                notifyDataSetChanged();
            } else {
                notifyDataSetInvalidated();
            }
        }
    }
}

... then in your onCreate:

String[] COUNTRIES = new String[] {"Belgium", "France", "Italy", "Germany"};
List<String> contriesList = Arrays.asList(COUNTRIES());
ArrayAdapter<String> adapter = new UnconditionalArrayAdapter<String>(this,
    android.R.layout.simple_dropdown_item_1line, contriesList);
AutoCompleteTextView textView = (AutoCompleteTextView)
    findViewById(R.id.countries_list);
textView.setAdapter(adapter);

The code is not tested, there can be some features with the filtering method I did not consider, but there you have it, the basic principles to emulate a ComboBox with an AutoCompleteTextView.

Edit Fixed NullFilter implementation. We need access on the items, thus the constructor of the UnconditionalArrayAdapter needs to take a reference to a List (kind of a buffer). You can also use e.g. adapter = new UnconditionalArrayAdapter<String>(..., new ArrayList<String>); and then use adapter.add("Luxemburg"), so you don't need to manage the buffer list.

I'm a little surprised that this question has been asked so many times before, but the most reuseable and friendly solution hasn't been documented.

I often have webpages using AngularJS, and when I click on a Save button, I'll "POST" this data back to my .aspx page or .ashx handler to save this back to the database. The data will be in the form of a JSON record.

On the server, to turn the raw posted data back into a C# class, here's what I would do.

First, define a C# class which will contain the posted data.

Supposing my webpage is posting JSON data like this:

{
    "UserID" : 1,
    "FirstName" : "Mike",
    "LastName" : "Mike",
    "Address1" : "10 Really Street",
    "Address2" : "London"
}

Then I'd define a C# class like this...

public class JSONRequest
{
    public int UserID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
}

(These classes can be nested, but the structure must match the format of the JSON data. So, if you're posting a JSON User record, with a list of Order records within it, your C# class should also contain a List<> of Order records.)

Now, in my .aspx.cs or .ashx file, I just need to do this, and leave JSON.Net to do the hard work...

    protected void Page_Load(object sender, EventArgs e)
    {
        string jsonString = "";
        HttpContext.Current.Request.InputStream.Position = 0;
        using (StreamReader inputStream = new StreamReader(this.Request.InputStream))
        {
            jsonString = inputStream.ReadToEnd();
        }
        JSONRequest oneQuestion = JsonConvert.DeserializeObject<JSONRequest>(jsonString);

And that's it. You now have a JSONRequest class containing the various fields which were POSTed to your server.

Another JS solution, that is easy and can be used to avoid a non-easy CSS-only or extra markup / hacky solution.

function minHeight(elm, percent) {
  var windowHeight = isNaN(window.innerHeight) ? 
                     window.clientHeight : window.innerHeight;
  var height = windowHeight * percent / 100;
  elm.style.minHeight = height + 'px';
}

W/ jQuery :

function minHeight($elm, percent) {
  var windowHeight = $(window).height();
  var height = windowHeight * percent / 100;
  $elm.css('min-height', height + 'px');
}

Angular directive :

myModule.directive('minHeight', ['$window', function($window) {
  return {
    restrict: 'A',
    link: function(scope, elm, attrs) {
      var windowHeight = isNaN($window.innerHeight) ? 
               $window.clientHeight : $window.innerHeight;
      var height = windowHeight * attrs.minHeight / 100;
      elm.css('min-height', height + 'px');
    }
  };
}]);

To be used like this :

<div>
  <!-- height auto here -->
  <div min-height="100">
    <!-- This guy is at least 100% of window height but grows if needed -->
  </div>
</div>

I find lambda useful for a list of functions that do the same, but for different circumstances.

Like the Mozilla plural rules:

plural_rules = [
    lambda n: 'all',
    lambda n: 'singular' if n == 1 else 'plural',
    lambda n: 'singular' if 0 <= n <= 1 else 'plural',
    ...
]
# Call plural rule #1 with argument 4 to find out which sentence form to use.
plural_rule[1](4) # returns 'plural'

If you'd have to define a function for all of those you'd go mad by the end of it.
Also, it wouldn't be nice with function names like plural_rule_1, plural_rule_2, etc. And you'd need to eval() it when you're depending on a variable function id.

use this

this.getWindow().setSoftInputMode(
            WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

SongsTableSeeder.php should be in database/seeds directory

Console command steps:

composer dump-autoload

and then:

php artisan cache:clear

and then:

php artisan optimize

and then:

php artisan db:seed

or:

php artisan db:seed --class=SongsTableSeeder

If you need to configure a set of unique property=value lines, I recommend a more concise loop. For example:

- name: Configure kernel parameters
  lineinfile:
    dest: /etc/sysctl.conf
    regexp: "^{{ item.property | regex_escape() }}="
    line: "{{ item.property }}={{ item.value }}"
  with_items:
    - { property: 'kernel.shmall', value: '2097152' }
    - { property: 'kernel.shmmax', value: '134217728' }
    - { property: 'fs.file-max', value: '65536' }

Using a dict as suggested by Alix Axel and adding automatic removing of matching commented out entries,

- name: Configure IPV4 Forwarding
  lineinfile:
    path: /etc/sysctl.conf
    regexp: "^#? *{{ item.key | regex_escape() }}="
    line: "{{ item.key }}={{ item.value }}"
  with_dict:
    'net.ipv4.ip_forward': 1

The semantics of Having

To better understand having, you need to see it from a theoretical point of view.

A group by is a query that takes a table and summarizes it into another table. You summarize the original table by grouping the original table into subsets (based upon the attributes that you specify in the group by). Each of these groups will yield one tuple.

The Having is simply equivalent to a WHERE clause after the group by has executed and before the select part of the query is computed.

Lets say your query is:

select a, b, count(*) 
from Table 
where c > 100 
group by a, b 
having count(*) > 10;

The evaluation of this query can be seen as the following steps:

1. Perform the WHERE, eliminating rows that do not satisfy it.
2. Group the table into subsets based upon the values of a and b (each tuple in each subset has the same values of a and b).
3. Eliminate subsets that do not satisfy the HAVING condition
4. Process each subset outputting the values as indicated in the SELECT part of the query. This creates one output tuple per subset left after step 3.

You can extend this to any complex query there Table can be any complex query that return a table (a cross product, a join, a UNION, etc).

In fact, having is syntactic sugar and does not extend the power of SQL. Any given query:

SELECT list 
FROM table
GROUP BY attrList
HAVING condition;

can be rewritten as:

SELECT list from (
   SELECT listatt 
   FROM table 
   GROUP BY attrList) as Name
WHERE condition;

The listatt is a list that includes the GROUP BY attributes and the expressions used in list and condition. It might be necessary to name some expressions in this list (with AS). For instance, the example query above can be rewritten as:

select a, b, count 
from (select a, b, count(*) as count
      from Table 
      where c > 100
      group by a, b) as someName
where count > 10;

The solution you need

Your solution seems to be correct:

SELECT s.sid, s.name
FROM Supplier s, Supplies su, Project pr
WHERE s.sid = su.sid AND su.jid = pr.jid
GROUP BY s.sid, s.name
HAVING COUNT (DISTINCT pr.jid) >= 2 

You join the three tables, then using sid as a grouping attribute (sname is functionally dependent on it, so it does not have an impact on the number of groups, but you must include it, otherwise it cannot be part of the select part of the statement). Then you are removing those that do not satisfy your condition: the satisfy pr.jid is >= 2, which is that you wanted originally.

Best solution to your problem

I personally prefer a simpler cleaner solution:

1. You need to only group by Supplies (sid, pid, jid**, quantity) to find the sid of those that supply at least to two projects.
2. Then join it to the Suppliers table to get the supplier same.

 SELECT sid, sname from
    (SELECT sid from supplies 
    GROUP BY sid, pid 
    HAVING count(DISTINCT jid) >= 2
    ) AS T1
NATURAL JOIN 
Supliers;

It will also be faster to execute, because the join is only done when needed, not all the times.

I often use git reset --mixed to revert a base version before multiple commits which you want to merge, then I make a new commit, that way could let your commit newest, assure your version is HEAD after you push to server.

Author: Ralph <[email protected]>
Date:   Thu Jun 13 16:44:12 2013 -0700

    Fixed a bug in space world automation

If I want to merge head two commits into one, first I use :

git reset --mixed 249cf9392da197573a17c8426c282

"249cf9392da197573a17c8426c282" was third version, also is your base version before you merge, after that, I make a new commit :

git add .
git commit -m 'some commit message'

It's all, hope is another way for everybody.

FYI, from git reset --help:

 --mixed
     Resets the index but not the working tree (i.e., the changed files are
     preserved but not marked for commit) and reports what has not been
     updated. This is the default action.

Lets take fibonacci series as an example

1,1,2,3,5,8,13,21....

first number: 1
Second number: 1
Third Number: 2

Another way to put it,

Bottom(first) number: 1
Top (Eighth) number on the given sequence: 21

In case of first five fibonacci number

Bottom(first) number :1
Top (fifth) number: 5 

Now lets take a look of recursive Fibonacci series algorithm as an example

public int rcursive(int n) {
    if ((n == 1) || (n == 2)) {
        return 1;
    } else {
        return rcursive(n - 1) + rcursive(n - 2);
    }
}

Now if we execute this program with following commands

rcursive(5);

if we closely look into the algorithm, in-order to generate fifth number it requires 3rd and 4th numbers. So my recursion actually start from top(5) and then goes all the way to bottom/lower numbers. This approach is actually top-down approach.

To avoid doing same calculation multiple times we use Dynamic Programming techniques. We store previously computed value and reuse it. This technique is called memoization. There are more to Dynamic programming other then memoization which is not needed to discuss current problem.

Top-Down

Lets rewrite our original algorithm and add memoized techniques.

public int memoized(int n, int[] memo) {
    if (n <= 2) {
        return 1;
    } else if (memo[n] != -1) {
        return memo[n];
    } else {
        memo[n] = memoized(n - 1, memo) + memoized(n - 2, memo);
    }
    return memo[n];
}

And we execute this method like following

   int n = 5;
    int[] memo = new int[n + 1];
    Arrays.fill(memo, -1);
    memoized(n, memo);

This solution is still top-down as algorithm start from top value and go to bottom each step to get our top value.

Bottom-Up

But, question is, can we start from bottom, like from first fibonacci number then walk our way to up. Lets rewrite it using this techniques,

public int dp(int n) {
    int[] output = new int[n + 1];
    output[1] = 1;
    output[2] = 1;
    for (int i = 3; i <= n; i++) {
        output[i] = output[i - 1] + output[i - 2];
    }
    return output[n];
}

Now if we look into this algorithm it actually start from lower values then go to top. If i need 5th fibonacci number i am actually calculating 1st, then second then third all the way to up 5th number. This techniques actually called bottom-up techniques.

Last two, algorithms full-fill dynamic programming requirements. But one is top-down and another one is bottom-up. Both algorithm has similar space and time complexity.

Simply write :

frame.validate();
frame.repaint();

That will do .

Regards

No, but it's been requested many times.

try like this (no pun intended btw)

script {
  try {
      sh 'do your stuff'
  } catch (Exception e) {
      echo 'Exception occurred: ' + e.toString()
      sh 'Handle the exception!'
  }
}

The key is to put try...catch in a script block in declarative pipeline syntax. Then it will work. This might be useful if you want to say continue pipeline execution despite failure (eg: test failed, still you need reports..)

var functionX = function() {
  var self = this;
  var functionY = function(y) {
    // If we call "this" in here, we get a reference to functionY,
    // but if we call "self" (defined earlier), we get a reference to function X.
  }
}

edit: in spite of, nested functions within an object takes on the global window object rather than the surrounding object.

I read a lot of answers but none seems to correctly explain where the word double comes from. I remember a very good explanation given by a University professor I had some years ago.

Recalling the style of VonC's answer, a single precision floating point representation uses a word of 32 bit.

• 1 bit for the sign, S
• 8 bits for the exponent, 'E'
• 24 bits for the fraction, also called mantissa, or coefficient (even though just 23 are represented). Let's call it 'M' (for mantissa, I prefer this name as "fraction" can be misunderstood).

Representation:

          S  EEEEEEEE   MMMMMMMMMMMMMMMMMMMMMMM
bits:    31 30      23 22                     0

(Just to point out, the sign bit is the last, not the first.)

A double precision floating point representation uses a word of 64 bit.

• 1 bit for the sign, S
• 11 bits for the exponent, 'E'
• 53 bits for the fraction / mantissa / coefficient (even though only 52 are represented), 'M'

Representation:

           S  EEEEEEEEEEE   MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM
bits:     63 62         52 51                                                  0

As you may notice, I wrote that the mantissa has, in both types, one bit more of information compared to its representation. In fact, the mantissa is a number represented without all its non-significative 0. For example,

• 0.000124 becomes 0.124 × 10^-3
• 237.141 becomes 0.237141 × 10³

This means that the mantissa will always be in the form

0.a₁a₂...a_t × ß^p

where ß is the base of representation. But since the fraction is a binary number, a₁ will always be equal to 1, thus the fraction can be rewritten as 1.a₂a₃...a_t+1 × 2^p and the initial 1 can be implicitly assumed, making room for an extra bit (a_t+1).

Now, it's obviously true that the double of 32 is 64, but that's not where the word comes from.

The precision indicates the number of decimal digits that are correct, i.e. without any kind of representation error or approximation. In other words, it indicates how many decimal digits one can safely use.

With that said, it's easy to estimate the number of decimal digits which can be safely used:

• single precision: log₁₀(2²⁴), which is about 7~8 decimal digits
• double precision: log₁₀(2⁵³), which is about 15~16 decimal digits

A temp table can be created in the caller and then populated from the called SP.

  create table #GetValuesOutputTable(
     ...   
  );

  exec GetValues; -- populates #GetValuesOutputTable

  select * from #GetValuesOutputTable;

Some advantages of this approach over the "insert exec" is that it can be nested and that it can be used as input or output.

Some disadvantages are that the "argument" is not public, the table creation exists within each caller, and that the name of the table could collide with other temp objects. It helps when the temp table name closely matches the SP name and follows some convention.

Taking it a bit farther, for output only temp tables, the insert-exec approach and the temp table approach can be supported simultaneously by the called SP. This doesn't help too much for chaining SP's because the table still need to be defined in the caller but can help to simplify testing from the cmd line or when calling externally.

  -- The "called" SP
  declare
      @returnAsSelect bit = 0;

  if object_id('tempdb..#GetValuesOutputTable') is null
  begin
      set @returnAsSelect = 1;
      create table #GetValuesOutputTable(
         ...   
      );
  end

  -- populate the table

  if @returnAsSelect = 1
      select * from #GetValuesOutputTable;

This is how the Angularjs team is doing it (v 1.6.5):

var msie, // holds major version number for IE, or NaN if UA is not IE.

// Support: IE 9-11 only
/**
 * documentMode is an IE-only property
 * http://msdn.microsoft.com/en-us/library/ie/cc196988(v=vs.85).aspx
 */
msie = window.document.documentMode;

Then there are several lines of code scattered throughout using it as a number such as

if (event === 'input' && msie <= 11) return false;

and

if (enabled && msie < 8) {

Firstly, System.currentTimeMillis() and Instant.now() are not ideal for timing. They both report the wall-clock time, which the computer doesn't know precisely, and which can move erratically, including going backwards if for example the NTP daemon corrects the system time. If your timing happens on a single machine then you should instead use System.nanoTime().

Secondly, from Java 8 onwards java.time.Duration is the best way to represent a duration:

long start = System.nanoTime();
// do things...
long end = System.nanoTime();
Duration duration = Duration.ofNanos(end - start);
System.out.println(duration); // Prints "PT18M19.511627776S"
System.out.printf("%d Hours %d Minutes %d Seconds%n",
        duration.toHours(), duration.toMinutes() % 60, duration.getSeconds() % 60);
// prints "0 Hours 18 Minutes 19 Seconds"

Use this formula:

=100% + (Year 2/Year 1)

The logic is that you recover 100% of the negative in year 1 (hence the initial 100%) plus any excess will be a ratio against year 1.

this is how you do it if you want to listen for the "Enter" key. There is an onKeydown prop that you can use and you can read about it in react doc

and here is a codeSandbox

const App = () => {
    const something=(event)=> {
        if (event.keyCode === 13) {
            console.log('enter')
        }
    }
return (
    <div className="App">
        <h1>Hello CodeSandbox</h1>
        <h2>Start editing to see some magic happen!</h2>
        <input  type='text' onKeyDown={(e) => something(e) }/>
    </div>
);
}

I prefer simple answers. No generators. No recursion or recursion limits. Just iteration:

def flatten(TheList):
    listIsNested = True

    while listIsNested:                 #outer loop
        keepChecking = False
        Temp = []

        for element in TheList:         #inner loop
            if isinstance(element,list):
                Temp.extend(element)
                keepChecking = True
            else:
                Temp.append(element)

        listIsNested = keepChecking     #determine if outer loop exits
        TheList = Temp[:]

    return TheList

This works with two lists: an inner for loop and an outer while loop.

The inner for loop iterates through the list. If it finds a list element, it (1) uses list.extend() to flatten that part one level of nesting and (2) switches keepChecking to True. keepchecking is used to control the outer while loop. If the outer loop gets set to true, it triggers the inner loop for another pass.

Those passes keep happening until no more nested lists are found. When a pass finally occurs where none are found, keepChecking never gets tripped to true, which means listIsNested stays false and the outer while loop exits.

The flattened list is then returned.

Test-run

flatten([1,2,3,4,[100,200,300,[1000,2000,3000]]])

[1, 2, 3, 4, 100, 200, 300, 1000, 2000, 3000]

When getting the following error,

you need to do the following.

Step 1: In Postman, click the wrench icon, go to settings, then go to the Proxy tab.

Step 2: Create a custom Proxy. This article explains how to create a custom proxy. After you create the custom Proxy, make sure you turn the Proxy toggle button to off. I put 61095 in for the proxy server and it worked for me.

Step 3 :

Success

This is sort of an indirect approach, but you could see if a website loads on your web browser of choice from whatever is running on port 80. Or you could telnet to port 80 and see if you get a response that gives you a clue as to what is running on that port and you can go shut it down. Since port 80 is the default port for http traffic chances are there is some sort of http server running there by default, but there's no guarantee.

$(window).height();   // returns height of browser viewport
$(document).height(); // returns height of HTML document

As documented here: http://api.jquery.com/height/

I'm a little late to the party, but I think my approach has the advantage that it lacks the use of EventEmitters and Subjects.

So, here's my approach. We can't get away from subscribe(), and we don't want to. In that vein, our service will return an Observable<T> with an observer that has our precious cargo. From the caller, we'll initialize a variable, Observable<T>, and it will get the service's Observable<T>. Next, we'll subscribe to this object. Finally, you get your "T"! from your service.

First, our people service, but yours doesnt pass parameters, that's more realistic:

people(hairColor: string): Observable<People> {
   this.url = "api/" + hairColor + "/people.json";

   return Observable.create(observer => {
      http.get(this.url)
          .map(res => res.json())
          .subscribe((data) => {
             this._people = data

             observer.next(this._people);
             observer.complete();


          });
   });
}

Ok, as you can see, we're returning an Observable of type "people". The signature of the method, even says so! We tuck-in the _people object into our observer. We'll access this type from our caller in the Component, next!

In the Component:

private _peopleObservable: Observable<people>;

constructor(private peopleService: PeopleService){}

getPeople(hairColor:string) {
   this._peopleObservable = this.peopleService.people(hairColor);

   this._peopleObservable.subscribe((data) => {
      this.people = data;
   });
}

We initialize our _peopleObservable by returning that Observable<people> from our PeopleService. Then, we subscribe to this property. Finally, we set this.people to our data(people) response.

Architecting the service in this fashion has one, major advantage over the typical service: map(...) and component: "subscribe(...)" pattern. In the real world, we need to map the json to our properties in our class and, sometimes, we do some custom stuff there. So this mapping can occur in our service. And, typically, because our service call will be used not once, but, probably, in other places in our code, we don't have to perform that mapping in some component, again. Moreover, what if we add a new field to people?....

    if (e.keyCode === 9) {
        e.preventDefault();
        // do work
    }

My own library for working with ES6 iterables (blinq) allows (among other things) easy multi-level sorting

const blinq = window.blinq.blinq_x000D_

// or const { blinq } = require('blinq')_x000D_
const dates = [{_x000D_
    day: 1, month: 10, year: 2000_x000D_
  },_x000D_

I know this is an old question, but still unanswered. It took me a day of research, but I found the simplest solution, at least in my case (Oracle 11.2 on Windows 2008 R2) and wanted to share.

The error, if looked at directly, indicates that the listener does not recognize the service name. But where does it keep service names? In %ORACLE_HOME%\NETWORK\ADMIN\listener.ora

The "SID_LIST" is just that, a list of SIDs and service names paired up in a format you can copy or lookup.

I added the problem Service Name, then in Windows "Services" control panel, I did a "Restart" on the Oracle listener service. Now all is well.

For example, your listener.ora file might initially look like:

# listener.ora Network Configuration File: C:\app\oracle_user\product\12.1.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\oracle_user\product\12.1.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\oracle_user\product\12.1.0\dbhome_1\bin\oraclr12.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

... And to make it recognize a service name of orcl, you might change it to:

# listener.ora Network Configuration File: C:\app\oracle_user\product\12.1.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\app\oracle_user\product\12.1.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\oracle_user\product\12.1.0\dbhome_1\bin\oraclr12.dll")
    )
    (SID_DESC = 
        (GLOBAL_DBNAME = orcl)
        (ORACLE_HOME = C:\app\oracle_user\product\12.1.0\dbhome_1)
        (SID_NAME = orcl)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

I had the same error happening when I had two different ASP.net projects in two different Visual Studio instances.
Closing one of them fixed the issue.

• Open Notepad++
• Paste your text
• Control + H

In the pop up

• Find what: \r\n
• Replace with: BLANK_SPACE

You end up with a big line. Then

• Control + H

In the pop up

• Find what: (\.)
• Replace with: \r\n

So you end up with lines that end by dot

And if you have to do the same process lots of times

• Go to Macro
• Start recording
• Do the process above
• Go to Macro
• Stop recording
• Save current recorded macro
• Choose a short cut
• Select the text you want to apply the process (Control + A)
• Do the shortcut

For example,

package main

import "fmt"

func CToGoString(c []byte) string {
    n := -1
    for i, b := range c {
        if b == 0 {
            break
        }
        n = i
    }
    return string(c[:n+1])
}

func main() {
    c := [100]byte{'a', 'b', 'c'}
    fmt.Println("C: ", len(c), c[:4])
    g := CToGoString(c[:])
    fmt.Println("Go:", len(g), g)
}

Output:

C:  100 [97 98 99 0]
Go: 3 abc

Siblings

$(this).index() can be used to get the index of the clicked element if the elements are siblings.

<div id="container">
    <a href="#" class="link">1</a>
    <a href="#" class="link">2</a>
    <a href="#" class="link">3</a>
    <a href="#" class="link">4</a>
</div>

$('#container').on('click', 'a', function() {
  console.log($(this).index());
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div id="container">
  <a href="#" class="link">1</a>
  <a href="#" class="link">2</a>
  <a href="#" class="link">3</a>
  <a href="#" class="link">4</a>
</div>

Not siblings

If no argument is passed to the .index() method, the return value is an integer indicating the position of the first element within the jQuery object relative to its sibling elements.

Pass the selector to the index(selector).

$(this).index(selector);

Example:

Find the index of the <a> element that is clicked.

<tr>
    <td><a href="#" class="adwa">0001</a></td>
</tr>
<tr>
    <td><a href="#" class="adwa">0002</a></td>
</tr>
<tr>
    <td><a href="#" class="adwa">0003</a></td>
</tr>
<tr>
    <td><a href="#" class="adwa">0004</a></td>
</tr>

Fiddle

$('#table').on('click', '.adwa', function() {
    console.log($(this).index(".adwa"));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<table id="table">
    <thead>
        <tr>
            <th>vendor id</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td><a href="#" class="adwa">0001</a></td>
        </tr>
        <tr>
            <td><a href="#" class="adwa">0002</a></td>
        </tr>
        <tr>
            <td><a href="#" class="adwa">0003</a></td>
        </tr>
        <tr>
            <td><a href="#" class="adwa">0004</a></td>
        </tr>
    </tbody>

Grega's answer is great in explaining why the original code does not work and two ways to fix the issue. However, this solution is not very flexible; consider the case where your closure includes a method call on a non-Serializable class that you have no control over. You can neither add the Serializable tag to this class nor change the underlying implementation to change the method into a function.

Nilesh presents a great workaround for this, but the solution can be made both more concise and general:

def genMapper[A, B](f: A => B): A => B = {
  val locker = com.twitter.chill.MeatLocker(f)
  x => locker.get.apply(x)
}

This function-serializer can then be used to automatically wrap closures and method calls:

rdd map genMapper(someFunc)

This technique also has the benefit of not requiring the additional Shark dependencies in order to access KryoSerializationWrapper, since Twitter's Chill is already pulled in by core Spark

here how I use it; This button inside my CameraActionActivity Activity class where I call camera

 btn_frag_camera.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intenImatToSec = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
                startActivityForResult(intenImatToSec, REQUEST_CODE_VIDEO);
                //intenImatToSec.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
                //intenImatToSec.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 10);
                //Toast.makeText(getActivity(), "Hello From Camera", Toast.LENGTH_SHORT).show();
            }
        });



@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {

            if (requestCode == REQUEST_CODE_IMG) {
                Bundle bundle = data.getExtras();
                Bitmap bitmap = (Bitmap) bundle.get("data");
                Intent intentBitMap = new Intent(getActivity(), DisplayImage.class);
                // aldigimiz imagi burda yonlendirdigimiz sinifa iletiyoruz
                ByteArrayOutputStream _bs = new ByteArrayOutputStream();
                bitmap.compress(Bitmap.CompressFormat.PNG, 50, _bs);
                intentBitMap.putExtra("byteArray", _bs.toByteArray());
                startActivity(intentBitMap);

            } else if (requestCode == REQUEST_CODE_VIDEO) {
                Uri videoUrl = data.getData();
                Intent intenToDisplayVideo = new Intent(getActivity(), DisplayVideo.class);
                intenToDisplayVideo.putExtra("videoUri", videoUrl.toString());
                startActivity(intenToDisplayVideo);
            }
        }
    }

And my other DisplayVideo Activity Class

VideoView videoView = (VideoView) findViewById(R.id.videoview_display_video_actvity);
Bundle extras = getIntent().getExtras();
        Uri myUri=  Uri.parse(extras.getString("videoUri"));
        videoView.setVideoURI(myUri);

Not sure if this is what you mean, but try setting las=1. Here's an example:

require(grDevices)
tN <- table(Ni <- stats::rpois(100, lambda=5))
r <- barplot(tN, col=rainbow(20), las=1)

That represents the style of axis labels. (0=parallel, 1=all horizontal, 2=all perpendicular to axis, 3=all vertical)

Actually, in C++14 it can be done with a very few lines of code.

This is a very similar in idea to @Paul's solution. Due to things missing from C++11, that solution is a bit unnecessarily bloated (plus defining in std smells). Thanks to C++14 we can make it a lot more readable.

The key observation is that range-based for-loops work by relying on begin() and end() in order to acquire the range's iterators. Thanks to ADL, one doesn't even need to define their custom begin() and end() in the std:: namespace.

Here is a very simple-sample solution:

// -------------------------------------------------------------------
// --- Reversed iterable

template <typename T>
struct reversion_wrapper { T& iterable; };

template <typename T>
auto begin (reversion_wrapper<T> w) { return std::rbegin(w.iterable); }

template <typename T>
auto end (reversion_wrapper<T> w) { return std::rend(w.iterable); }

template <typename T>
reversion_wrapper<T> reverse (T&& iterable) { return { iterable }; }

This works like a charm, for instance:

template <typename T>
void print_iterable (std::ostream& out, const T& iterable)
{
    for (auto&& element: iterable)
        out << element << ',';
    out << '\n';
}

int main (int, char**)
{
    using namespace std;

    // on prvalues
    print_iterable(cout, reverse(initializer_list<int> { 1, 2, 3, 4, }));

    // on const lvalue references
    const list<int> ints_list { 1, 2, 3, 4, };
    for (auto&& el: reverse(ints_list))
        cout << el << ',';
    cout << '\n';

    // on mutable lvalue references
    vector<int> ints_vec { 0, 0, 0, 0, };
    size_t i = 0;
    for (int& el: reverse(ints_vec))
        el += i++;
    print_iterable(cout, ints_vec);
    print_iterable(cout, reverse(ints_vec));

    return 0;
}

prints as expected

4,3,2,1,
4,3,2,1,
3,2,1,0,
0,1,2,3,

NOTE std::rbegin(), std::rend(), and std::make_reverse_iterator() are not yet implemented in GCC-4.9. I write these examples according to the standard, but they would not compile in stable g++. Nevertheless, adding temporary stubs for these three functions is very easy. Here is a sample implementation, definitely not complete but works well enough for most cases:

// --------------------------------------------------
template <typename I>
reverse_iterator<I> make_reverse_iterator (I i)
{
    return std::reverse_iterator<I> { i };
}

// --------------------------------------------------
template <typename T>
auto rbegin (T& iterable)
{
    return make_reverse_iterator(iterable.end());
}

template <typename T>
auto rend (T& iterable)
{
    return make_reverse_iterator(iterable.begin());
}

// const container variants

template <typename T>
auto rbegin (const T& iterable)
{
    return make_reverse_iterator(iterable.end());
}

template <typename T>
auto rend (const T& iterable)
{
    return make_reverse_iterator(iterable.begin());
}

I personnaly like to map esc to the command :noh as follow:

map <esc> :noh<cr>

I wrote a whole article recently about Vim search: how to search on vanilla Vim and the best plugin to enhance the search features.

Given your edited problem description, I'd suggest using COALESCE() instead of that unwieldy CASE expression:

SELECT FullName
FROM (
  SELECT COALESCE(LastName+', '+FirstName, FirstName) AS FullName
  FROM customers
) c
GROUP BY FullName;

It's of use for everything that has to scale according to the font size.

It's especially useful on browsers which implement zoom by scaling the font size. So if you size all your elements using em they scale accordingly.

It doesn't work if you use Function, but works if you Sub. However, you cannot call a sub from a cell using formula.

I'd like to suggest a yet-unmentioned solution: use CSS3's calc() to mix % and px units. calc() has excellent support nowadays, and it allows for fast construction of quite complex layouts.

Here's a JSFiddle link for the code below.

HTML:

<div class="sidebar">
  sidebar fixed width
</div>
<div class="content">
  content flexible width
</div>

CSS:

.sidebar {
    width: 180px;
    float: right;
    background: green;
}

.content {
    width: calc(100% - 180px);
    background: orange;
}

And here's another JSFiddle demonstrating this concept applied to a more complex layout. I used SCSS here since its variables allow for flexible and self-descriptive code, but the layout can be easily re-created in pure CSS if having "hard-coded" values is not an issue.

First you need to get the counts for each category, i.e. how many Bads and Goods and so on are there for each group (Food, Music, People). This would be done like so:

raw <- read.csv("http://pastebin.com/raw.php?i=L8cEKcxS",sep=",")
raw[,2]<-factor(raw[,2],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,3]<-factor(raw[,3],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,4]<-factor(raw[,4],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)

raw=raw[,c(2,3,4)] # getting rid of the "people" variable as I see no use for it

freq=table(col(raw), as.matrix(raw)) # get the counts of each factor level

Then you need to create a data frame out of it, melt it and plot it:

Names=c("Food","Music","People")     # create list of names
data=data.frame(cbind(freq),Names)   # combine them into a data frame
data=data[,c(5,3,1,2,4)]             # sort columns

# melt the data frame for plotting
data.m <- melt(data, id.vars='Names')

# plot everything
ggplot(data.m, aes(Names, value)) +   
  geom_bar(aes(fill = variable), position = "dodge", stat="identity")

Is this what you're after?

To clarify a little bit, in ggplot multiple grouping bar you had a data frame that looked like this:

> head(df)
  ID Type Annee X1PCE X2PCE X3PCE X4PCE X5PCE X6PCE
1  1    A  1980   450   338   154    36    13     9
2  2    A  2000   288   407   212    54    16    23
3  3    A  2020   196   434   246    68    19    36
4  4    B  1980   111   326   441    90    21    11
5  5    B  2000    63   298   443   133    42    21
6  6    B  2020    36   257   462   162    55    30

Since you have numerical values in columns 4-9, which would later be plotted on the y axis, this can be easily transformed with reshape and plotted.

For our current data set, we needed something similar, so we used freq=table(col(raw), as.matrix(raw)) to get this:

> data
   Names Very.Bad Bad Good Very.Good
1   Food        7   6    5         2
2  Music        5   5    7         3
3 People        6   3    7         4

Just imagine you have Very.Bad, Bad, Good and so on instead of X1PCE, X2PCE, X3PCE. See the similarity? But we needed to create such structure first. Hence the freq=table(col(raw), as.matrix(raw)).

This can be done with MySQL, although it's highly unintuitive:

CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
  DECLARE a,b INT;
  DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
  DECLARE CONTINUE HANDLER FOR NOT FOUND
  SET b = 1;
  OPEN cur_1;
  REPEAT
    FETCH cur_1 INTO a;
    UNTIL b = 1
  END REPEAT;
  CLOSE cur_1;
  SET return_val = a;
END;//

In my case I was doing this:

double a = (double) (MAX_BANDWIDTH_SHARED_MB/(qCount+1));

Instead of the "correct" :

double a = (double)MAX_BANDWIDTH_SHARED_MB/(qCount+1);

Take attention with the parentheses !

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

Last three characters of string:

${string: -3}

or

${string:(-3)}

(mind the space between : and -3 in the first form).

Please refer to the Shell Parameter Expansion in the reference manual:

${parameter:offset}
${parameter:offset:length}

Expands to up to length characters of parameter starting at the character
specified by offset. If length is omitted, expands to the substring of parameter
starting at the character specified by offset. length and offset are arithmetic
expressions (see Shell Arithmetic). This is referred to as Substring Expansion.

If offset evaluates to a number less than zero, the value is used as an offset
from the end of the value of parameter. If length evaluates to a number less than
zero, and parameter is not ‘@’ and not an indexed or associative array, it is
interpreted as an offset from the end of the value of parameter rather than a
number of characters, and the expansion is the characters between the two
offsets. If parameter is ‘@’, the result is length positional parameters
beginning at offset. If parameter is an indexed array name subscripted by ‘@’ or
‘*’, the result is the length members of the array beginning with
${parameter[offset]}. A negative offset is taken relative to one greater than the
maximum index of the specified array. Substring expansion applied to an
associative array produces undefined results.

Note that a negative offset must be separated from the colon by at least one
space to avoid being confused with the ‘:-’ expansion. Substring indexing is
zero-based unless the positional parameters are used, in which case the indexing
starts at 1 by default. If offset is 0, and the positional parameters are used,
$@ is prefixed to the list.

Since this answer gets a few regular views, let me add a possibility to address John Rix's comment; as he mentions, if your string has length less than 3, ${string: -3} expands to the empty string. If, in this case, you want the expansion of string, you may use:

${string:${#string}<3?0:-3}

This uses the ?: ternary if operator, that may be used in Shell Arithmetic; since as documented, the offset is an arithmetic expression, this is valid.

Update for a POSIX-compliant solution

The previous part gives the best option when using Bash. If you want to target POSIX shells, here's an option (that doesn't use pipes or external tools like cut):

# New variable with 3 last characters removed
prefix=${string%???}
# The new string is obtained by removing the prefix a from string
newstring=${string#"$prefix"}

One of the main things to observe here is the use of quoting for prefix inside the parameter expansion. This is mentioned in the POSIX ref (at the end of the section):

The following four varieties of parameter expansion provide for substring processing. In each case, pattern matching notation (see Pattern Matching Notation), rather than regular expression notation, shall be used to evaluate the patterns. If parameter is '#', '*', or '@', the result of the expansion is unspecified. If parameter is unset and set -u is in effect, the expansion shall fail. Enclosing the full parameter expansion string in double-quotes shall not cause the following four varieties of pattern characters to be quoted, whereas quoting characters within the braces shall have this effect. In each variety, if word is omitted, the empty pattern shall be used.

This is important if your string contains special characters. E.g. (in dash),

$ string="hello*ext"
$ prefix=${string%???}
$ # Without quotes (WRONG)
$ echo "${string#$prefix}"
*ext
$ # With quotes (CORRECT)
$ echo "${string#"$prefix"}"
ext

Of course, this is usable only when then number of characters is known in advance, as you have to hardcode the number of ? in the parameter expansion; but when it's the case, it's a good portable solution.

For those who are on SunOS which is non-GNU, the following code will help:

sed '1i\^J
line to add' test.dat > tmp.dat

• ^J is inserted with ^V+^J
• Add the newline after '1i.
• \ MUST be the last character of the line.
• The second part of the command must be in a second line.

Google Map API request and parse DirectionsResponse with C#, change the json in your url to xml and use the following code to turn the result into a usable C# Generic List Object.

I hope this will help someone.

From your example, it seems to me you want to use a static method.

class mystuff:
  @staticmethod
  def average(a,b,c): #get the average of three numbers
    result=a+b+c
    result=result/3
    return result

print mystuff.average(9,18,27)

Please note that an heavy usage of static methods in python is usually a symptom of some bad smell - if you really need functions, then declare them directly on module level.

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

I developed a method that slightly beats memcmp() (plinth's answer) and very slighly beats EqualBytesLongUnrolled() (Arek Bulski's answer) on my PC. Basically, it unrolls the loop by 4 instead of 8.

Update 30 Mar. 2019:

The command pg_lsclusters (at least under Linux / Ubuntu) can be used to list the existing clusters and with it also the data directory:

Ver Cluster Port Status Owner    Data directory               Log file
9.5 main    5433 down   postgres /var/lib/postgresql/9.5/main /var/log/postgresql/postgresql-9.5-main.log
10  main    5432 down   postgres /var/lib/postgresql/10/main  /var/log/postgresql/postgresql-10-main.log

First, it depends on your version of R. If you've passed 2.11, you can use aggreggate with multiple results functions(summary, by instance, or your own function). If not, you can use the answer made by Justin.

You could use the toJSON() JavaScript method, it converts a JavaScript DateTime to what C# can recognise as a DateTime.

The JavaScript code looks like this

var date = new Date();
date.toJSON(); // this is the JavaScript date as a c# DateTime

Note: The result will be in UTC time

System.out.println(char1+""+char2+char3)

or

String s = char1+""+char2+char3;

This can be used to print all the answers as well

public void recur(int[] a, int n, int sum, int[] ans, int ind) {
    if (n < 0 && sum != 0)
        return;
    if (n < 0 && sum == 0) {
        print(ans, ind);
        return;
    }
    if (sum >= a[n]) {
        ans[ind] = a[n];
        recur(a, n - 1, sum - a[n], ans, ind + 1);
    }
    recur(a, n - 1, sum, ans, ind);
}

public void print(int[] a, int n) {
    for (int i = 0; i < n; i++)
        System.out.print(a[i] + " ");
    System.out.println();
}

Time Complexity is exponential. Order of 2^n

ssh-keygen -i -m PKCS8 -f public-key.pem

here is anaother way to limit your filter on html, for example I want to display 3 list at time than i will use limitTo:3

  <li ng-repeat="phone in phones | limitTo:3">
    <p>Phone Name: {{phone.name}}</p>
  </li>

You just need to type a command in flutter_console.bat type flutter config --android-sdk <path-to-your-android-sdk-path>

This works on SQL Server 2000.

use master
select count(*) From sysxlogins WHERE NAME = 'myUsername'

on SQL 2005, change the 2nd line to

select count(*) From syslogins WHERE NAME = 'myUsername'

I'm not sure about SQL 2008, but I'm guessing that it will be the same as SQL 2005 and if not, this should give you an idea of where t start looking.

According to the latest version (select2 3.4.5) documented here, it would be as simple as:

 $("#my_select").select2("val", "");

C++ is faster on average (as it was initially, largely a superset of C, though there are some differences). However, for specific benchmarks, there is often another language which is faster.

https://benchmarksgame-team.pages.debian.net/benchmarksgame/

fannjuch-redux was fastest in Scala

n-body and fasta were faster in Ada.

spectral-norm was fastest in Fortran.

reverse-complement, mandelbrot and pidigits were fastest in ATS.

regex-dna was fastest in JavaScript.

chameneou-redux was fastest is Java 7.

thread-ring was fastest in Haskell.

The rest of the benchmarks were fastest in C or C++.

I'm just adding this answer here as it's the quickest solution for me. Just set the default database engine to 'InnoDB' on

/config/database.php

'mysql' => [
    ...,
    ...,
    'engine' => 'InnoDB',
 ]

then run php artisan config:cache to clear and refresh the configuration cache

EDIT: Answers found here might explain what's behind the scenes of this one

Try this:

[(i, j) for i, j in enumerate(mylist)]

You need to put i,j inside a tuple for the list comprehension to work. Alternatively, given that enumerate() already returns a tuple, you can return it directly without unpacking it first:

[pair for pair in enumerate(mylist)]

Either way, the result that gets returned is as expected:

> [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

converting object id to string(using toString() method) will do the job.

json.dumps() is much more than just making a string out of a Python object, it would always produce a valid JSON string (assuming everything inside the object is serializable) following the Type Conversion Table.

For instance, if one of the values is None, the str() would produce an invalid JSON which cannot be loaded:

>>> data = {'jsonKey': None}
>>> str(data)
"{'jsonKey': None}"
>>> json.loads(str(data))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)

But the dumps() would convert None into null making a valid JSON string that can be loaded:

>>> import json
>>> data = {'jsonKey': None}
>>> json.dumps(data)
'{"jsonKey": null}'
>>> json.loads(json.dumps(data))
{u'jsonKey': None}

By default the function returns FALSE (boolean) if the segment does not exist. There is an optional second parameter that permits you to set your own default value if the segment is missing. For example, this would tell the function to return the number zero in the event of failure: $product_id = $this->uri->segment(3, 0);

It helps avoid having to write code like this:

[if ($this->uri->segment(3) === FALSE)
{
    $product_id = 0;
}
else
{
    $product_id = $this->uri->segment(3);
}]

If you want N digits, add 10^N and delete the first digit.

for (( num=100; num<=105; num++ ))
do
  echo ${num:1:3}
done

Output:

01
02
03
04
05

I solved the issue by removing "type": "module" field from package.json.

If you want to add also the rest of the values in the lists you can use this (this is working in Python3.5)

def addVectors(v1, v2):
    sum = [x + y for x, y in zip(v1, v2)]
    if not len(v1) >= len(v2):
        sum += v2[len(v1):]
    else:
        sum += v1[len(v2):]

    return sum


#for testing 
if __name__=='__main__':
    a = [1, 2]
    b = [1, 2, 3, 4]
    print(a)
    print(b)
    print(addVectors(a,b))

Note that the reason topicId was "not defined" per the error message is that it existed as a local variable when the setTimeout was executed, but not when the delayed call to postinsql happened. Variable lifetime is especially important to pay attention to, especially when trying something like passing "this" as an object reference.

I heard that you can pass topicId as a third parameter to the setTimeout function. Not much detail is given but I got enough information to get it to work, and it's successful in Safari. I don't know what they mean about the "millisecond error" though. Check it out here:

http://www.howtocreate.co.uk/tutorials/javascript/timers

have you considered having your app simply use a new renamed topic? (i.e. a topic that is named like the original topic but with a "1" appended at the end).

That would also give your app a fresh clean topic.

Joining fails if the DataFrames have some column names in common. The simplest way around it is to include an lsuffix or rsuffix keyword like so:

restaurant_review_frame.join(restaurant_ids_dataframe, on='business_id', how='left', lsuffix="_review")

This way, the columns have distinct names. The documentation addresses this very problem.

Or, you could get around this by simply deleting the offending columns before you join. If, for example, the stars in restaurant_ids_dataframe are redundant to the stars in restaurant_review_frame, you could del restaurant_ids_dataframe['stars'].

You are specifying .fixedbutton in your CSS (a class) and specifying the id on the element itself.

Change your CSS to the following, which will select the id fixedbutton

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
}

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

Update your connection string as shown below (without port variable as well):

MysqlConn.ConnectionString = "Server=127.0.0.1;Database=patholabs;Uid=pankaj;Pwd=master;"

Hope this helps...

It's quite common to run Tomcat behind Apache. In Apache you can then direct certain URLs to Tomcat, and have Apache/PHP handle the others (including the static images).

(On Unix, Tomcat itself cannot securely made to run on port 80, while Apache can. Tomcat, being a Java process, would be required to run as root, while Apache will switch to non-root privileges as soon as port 80 has been claimed. So, running Apache on port 80 and have it redirect some or all requests to Tomcat, is quite common on Unix.)

I encountered this problem too, then i modified 'localhost' to '127.0.0.1',it works.

These are my two suggestions.

1. Using classes. There is no need to specify width of the two other columns as they will be set to 15% each automatically by the browser.

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       .subject { width: 70%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th class="subject">Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

2. Without using classes. Three different methods but the result is identical.

   a)

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       th+th { width: 70%; }_x000D_
       th+th+th { width: 15%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th>Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

   b)

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       th:nth-of-type(2) { width: 70%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th>Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

   c) This one is my favourite. Same as b) but with better browser support.

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       th:first-child+th { width: 70%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th>Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

for me adding / worked at the end of location of folder. Hence, if you are copying into folder, don't forget to put /

Apparently match_parent is :

• NOT OK for views directly under ConstraintLayout
• OK for views nested inside of views that are directly under ConstraintLayout

So if you need your views to function as match_parent, then:

1. Direct children of ConstraintLayout should use 0dp
2. Nested elements (eg, grandchild to ConstraintLayout) can use match_parent

Example:

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="16dp">

    <android.support.design.widget.TextInputLayout
        android:id="@+id/phoneNumberInputLayout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/phoneNumber"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    </android.support.design.widget.TextInputLayout>

As Shafik already wrote you need to use the right format because scanf gets you a char. Don't hesitate to look here if u aren't sure about the usage: http://www.cplusplus.com/reference/cstdio/printf/

Hint: It's faster/nicer to write x=x+1; the shorter way: x++;

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.

Solution 1 : You can do like this :

List<car> result = GetSomeOtherList().Except(GetTheList()).ToList();

But in some cases may this solution not work. if it is not work you can use my second solution .

Solution 2 :

List<car> list1 = GetTheList();
List<car> list2 = GetSomeOtherList();

we pretend that list1 is your main list and list2 is your secondry list and you want to get items of list1 without items of list2.

 var result =  list1.Where(p => !list2.Any(x => x.ID == p.ID && x.property1 == p.property1)).ToList();

In case someone is using Laravel and is getting this problem. I was getting this as well and the issue was in the order in which I was inserting the ids (i.e., the foreign keys) in the pivot table.

To be concrete, find below an example for a many to many relationship:

wordtokens <-> wordtoken_wordchunk <-> wordchunks

// wordtoken_wordchunk table
Schema::create('wordtoken_wordchunk', function(Blueprint $table) {
        $table->integer('wordtoken_id')->unsigned();
        $table->integer('wordchunk_id')->unsigned();

        $table->foreign('wordtoken_id')->references('id')->on('word_tokens')->onDelete('cascade');
        $table->foreign('wordchunk_id')->references('id')->on('wordchunks')->onDelete('cascade');

        $table->primary(['wordtoken_id', 'wordchunk_id']);
    });

// wordchunks table
Schema::create('wordchunks', function (Blueprint $table) {
        $table->increments('id');
        $table->timestamps();
        $table->string('text');
    });

// wordtokens table
Schema::create('word_tokens', function (Blueprint $table) {
        $table->increments('id');
        $table->string('text');
});

Now my models look like follows:

class WordToken extends Model
{
   public function wordchunks() {
      return $this->belongsToMany('App\Wordchunk');
   }
}

class Wordchunk extends Model
{

    public function wordTokens() {
        return $this->belongsToMany('App\WordToken', 'wordtoken_wordchunk', 'wordchunk_id', 'wordtoken_id');
    }
}

I fixed the problem by exchanging the order of 'wordchunk_id' and 'wordtoken_id' in the Wordchunk model.

For code completion, this is how I persist the models:

private function persistChunks($chunks) {
    foreach ($chunks as $chunk) {
        $model = new Wordchunk();
        $model->text = implode(' ', array_map(function($token) {return $token->text;}, $chunk));
        $tokenIds = array_map(function($token) {return $token->id;}, $chunk);
        $model->save();
        $model->wordTokens()->attach($tokenIds);
    }
}

1. literal_eval, a somewhat safer version of eval (will only evaluate literals ie strings, lists etc):

   from ast import literal_eval
   
   python_dict = literal_eval("{'a': 1}")
   

2. json.loads but it would require your string to use double quotes:

   import json
   
   python_dict = json.loads('{"a": 1}')
   

I prefer feature before layers, but I guess it depends on you project. Consider your forces:

• Dependencies
  Try minimize package dependencies, especially between features. Extract APIs if necessary.
• Team organization
  In some organizations teams work on features and in others on layers. This influence how code is organized, use it to formalize APIs or encourage cooperation.
• Deployment and versioning
  Putting everything into a module make deployment and versioning simpler, but bug fixing harder. Splitting things enable better control, scalability and availability.
• Respond to change
  Well organized code is much simpler to change than a big ball of mud.
• Size (people and lines of code)
  The bigger the more formalized/standardized it needs to be.
• Importance/quality
  Some code is more important than other. APIs should be more stable then the implementation. Therefore it needs to be clearly separated.
• Level of abstraction and entry point
  It should be possible for an outsider to know what the code is about, and where to start reading from looking at the package tree.

Example:

com/company/module
  + feature1/
    - MainClass          // The entry point for exploring
    + api/               // Public interface, used by other features
    + domain/
      - AggregateRoot
      + api/             // Internal API, complements the public, used by web
      + impl/ 
    + persistence/       
    + web/               // presentation layer 
    + services/          // Rest or other remote API 
    + support/            
  + feature2/
  + support/             // Any support or utils used by more than on feature
    + io
    + config
    + persistence
    + web

This is just an example. It is quite formal. For example it defines 2 interfaces for feature1. Normally that is not required, but could be a good idea if used differently by different people. You may let the internal API extend the public.

I do not like the 'impl' or 'support' names, but they help separate the less important stuff from the important (domain and API). When it comes to naming I like to be as concrete as possible. If you have a package called 'utils' with 20 classes, move StringUtils to support/string, HttpUtil to support/http and so on.

In my case error caused next. I've tried to execute commands globally i.e outside of any target.

UPD. To run command globally one must be properly formed. For example command

ln -sf ../../user/curl/$SRC_NAME ./$SRC_NAME

would become:

$(shell ln -sf ../../user/curl/$(SRC_NAME) ./$(SRC_NAME))

Clone is broken, so dont use it.

THE CLONE METHOD of the Object class is a somewhat magical method that does what no pure Java method could ever do: It produces an identical copy of its object. It has been present in the primordial Object superclass since the Beta-release days of the Java compiler*; and it, like all ancient magic, requires the appropriate incantation to prevent the spell from unexpectedly backfiring

Prefer a method that copies the object

Foo copyFoo (Foo foo){
  Foo f = new Foo();
  //for all properties in FOo
  f.set(foo.get());
  return f;
}

By default node will run on every IP address exposed by the host on which it runs. You don't need to do anything special. You already knew the server runs on a particular port. You can prove this, by using that IP address on a browser on that machine:

http://my-ip-address:port

If that didn't work, you might have your IP address wrong.

So it was a problem of encoding. Iconv solves the problem

The reality is, these states do not work as they should for all users. Not using all three selectors creates accessibility issues for many keyboard-only users who are physically unable to use a mouse. I invite you to take the #nomouse challenge (nomouse dot org).

Not 100%; however, it sounds like the heap is an object or set of allocated space (on RAM) that is built into the functionality of the code either Java itself or more likely functionality from ehcache itself, and the off-heap Ram is there own system as well; however, it sounds like this is one magnitude slower as it is not as organized, meaning it may not use a heap (meaning one long set of space of ram), and instead uses different address spaces likely making it slightly less efficient.

Then of course the next tier lower is hard-drive space itself.

I don't use ehcache, so you may not want to trust me, but that what is what I gathered from their documentation.

(Assuming you are looking at the reports in the Crystal Report Designer...)

Your menu options might be a little different depending on the version of Crystal Reports you're using, but you can either:

• Make a summary field: Right-click on the desired formula field in your detail section and choose "Insert Summary". Choose "sum" from the drop-down box and verify that the correct account grouping is selected, then click OK. You will then have a simple sum field in your group footer section.
• Make a running total field: Click on the "Insert" menu and choose "Running Total Field..."*** Click on the New button and give your new running total field a name. Choose your formula field under "Field to summarize" and choose "sum" under "Type of Summary". Here you can also change when the total is evaluated and reset, leave these at their default if you're wanting a sum on each record. You can also use a formula to determine when a certain field should be counted in the total. (Evaluate: Use Formula)

You probably need more blur and a little less spread.

My Answer: All of the following should be overridden (i.e. describe them all within columndefinition, if appropriate):

• length
• precision
• scale
• nullable
• unique

i.e. the column DDL will consist of: name + columndefinition and nothing else.

Rationale follows.

1. Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.

2. Other annotation purely logical - properties used in-memory in java to control JPA processing.

3. That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true) and once via @Column(...,nullable=true). Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.

In your example, length and nullable properties are overridden and redundant.

So, when specifying columnDefinition, what other properties of @Column are made redundant?

1. In JPA Spec & javadoc:

   • columnDefinition definition: The SQL fragment that is used when generating the DDL for the column.

   • columnDefinition default: Generated SQL to create a column of the inferred type.

   • The following examples are provided:

     @Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
     @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
     

   • And, err..., that's it really. :-$ ?!

   Does columnDefinition override other properties provided in the same annotation?

   The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.

2. The following can be safely implied from examples provided in the JPA spec

   • name & table can be used in conjunction with columnDefinition, neither are overridden
   • nullable is overridden/made redundant by columnDefinition

3. The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):

   • length, precision, scale are overridden/made redundant by the columnDefinition - they are integral to the type
   • insertable and updateable are provided separately and never included in columnDefinition, because they control SQL generation in-memory, before it is emmitted to the database.

4. That leaves just the "unique" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.

Test My Answer For columns "A" & "B", respectively:

  @Column(name="...", table="...", insertable=true, updateable=false,
          columndefinition="NUMBER(5,2) NOT NULL UNIQUE"

  @Column(name="...", table="...", insertable=false, updateable=true,
          columndefinition="NVARCHAR2(100) NULL"

• confirm generated table has correct type/nullability/uniqueness
• optionally, do JPA insert & update: former should include column A, latter column B

This seems to be the best solution as it takes multiple parameters of the same name into consideration.

    function paramsToJSON(str) {
        var pairs = str.split('&');
        var result = {};
        pairs.forEach(function(pair) {
            pair = pair.split('=');
            var name = pair[0]
            var value = pair[1]
            if( name.length )
                if (result[name] !== undefined) {
                    if (!result[name].push) {
                        result[name] = [result[name]];
                    }
                    result[name].push(value || '');
                } else {
                    result[name] = value || '';
                }
        });
        return( result );
    }

<a href="index.html?x=1&x=2&x=3&y=blah">something</a>
paramsToJSON("x=1&x=2&x=3&y=blah"); 

console yields => {x: Array[3], y: "blah"} where x is an array as is proper JSON

I later decided to convert it to a jQuery plugin too...

$.fn.serializeURLParams = function() {
    var result = {};

    if( !this.is("a") || this.attr("href").indexOf("?") == -1 ) 
        return( result );

    var pairs = this.attr("href").split("?")[1].split('&');
    pairs.forEach(function(pair) {
        pair = pair.split('=');
        var name = decodeURI(pair[0])
        var value = decodeURI(pair[1])
        if( name.length )
            if (result[name] !== undefined) {
                if (!result[name].push) {
                    result[name] = [result[name]];
                }
                result[name].push(value || '');
            } else {
                result[name] = value || '';
            }
    });
    return( result )
}

<a href="index.html?x=1&x=2&x=3&y=blah">something</a>
$("a").serializeURLParams(); 

console yields => {x: Array[3], y: "blah"} where x is an array as is proper JSON

Now, the first will accept the parameters only but the jQuery plugin will take the whole url and return the serialized parameters.

You will need to make sure that if you're using a test environment like WAMP set your username as root. Here is an example which connects to a MySQL database, issues your query, and outputs <option> tags for a <select> box from each row in the table.

<?php

mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');

$sql = "SELECT PcID FROM PC";
$result = mysql_query($sql);

echo "<select name='PcID'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['PcID'] . "'>" . $row['PcID'] . "</option>";
}
echo "</select>";

?>

1. Open SQL server Management Studio.
2. Go to Connect to Server and select the Server Type as Integration Services and give the Server Name then click connect.
3. Go to Object Explorer on the left corner.
4. You can see the Stored Package folder in Object Explorer.
5. Expand the Stored Package folder, here you can see the SSIS interfaces.

Just to add to this. You will get this error too, when you are running ng serve not from within your project folder. So always make sure your bash runs from your project folder.

The opposite of the == compare operator is !=.

if you want to know the install version of Xcode as well as Swift language current version:

Use below simple command by using Terminal:

1. To get install Xcode Version

 xcodebuild -version

2. To get install Swift language Version

swift --version

If you want to ALWAYS exclude certain properties for any class, you could use setMixInResolver method:

    @JsonIgnoreProperties({"id", "index", "version"})
    abstract class MixIn {
    }

    mapper.setMixInResolver(new ClassIntrospector.MixInResolver(){
        @Override
        public Class<?> findMixInClassFor(Class<?> cls) {
            return MixIn.class;  
        }

        @Override
        public ClassIntrospector.MixInResolver copy() {
            return this;
        }
    });

I would need to display the jobid, jobname and 5 fields called Priority1, Priority2, Priority3, Priority4. Priority5.

Something's wrong with your query design. You're showing a specific job in each row as well, and so you'll either have a situation where ever row has four priority columns with a '0' and one priority column with a '1' (the priority for that job) or you'll end up repeating the count for all priorities on every row.

What do you really want to show here?

The user's input will always be given to you in the form of a string of characters... if you want to convert the user's input from a string to an integer, you'll need to supply the code to do that. If the user types in a number (e.g. "1"), you can pass the string to atoi() to get the integer corresponding to the string. If the user types in an english string (e.g. "EASY") then you'll need to check for that string (e.g. with strcmp()) and assign the appropriate integer value to your variable based on which check matches. Once you have an integer value that was derived from the user's input string, you can pass it into the switch() statement as usual.

Came across this question researching some aberrant behavior in IE, specifically IE9, didn't check older versions. It seems

window.location.reload();

results in a refresh that blanks out the entire screen for a second, where as

 window.location = document.URL;

refreshes the page much more quickly, almost imperceptibly.

Doing a bit more research, and some experimentation with fiddler, it seems that window.location.reload() will bypass the cache and reload from the server regardless if you pass the boolean with it or not, this includes getting all of your assets (images, scripts, style sheets, etc) again. So if you just want the page to refresh the HTML, the window.location = document.URL will return much quicker and with less traffic.

A difference in behavior between browsers is that when IE9 uses the reload method it clears the visible page and seemingly rebuilds it from scratch, where FF and chrome wait till they get the new assets and rebuild them if they are different.

You can add the following in your .bashrc

if [ "$TERM" = xterm ]; then TERM=xterm-256color; fi

I literally just wanted the first row of my data which are the headers I need and didn't want to iterate over all my data to get them, so I just did this:

with open(data, 'r', newline='') as csvfile:
t = 0
for i in csv.reader(csvfile, delimiter=',', quotechar='|'):
    if t > 0:
        break
    else:
        dbh = i
        t += 1

I know it's late in the day but might help someone else!

just edit wp_user table with your phpmyadmin, and choose MD5 on Function field then input your new password, save it (go button).

You should change your code as below:

BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();

List<String> s = new ArrayList<String>();
for(BluetoothDevice bt : pairedDevices)
   s.add(bt.getName());

setListAdapter(new ArrayAdapter<String>(this, R.layout.list, s));

If you are using PHP >= 7.2 consider using inbuilt sodium core extension for encrption.

It is modern and more secure. You can find more information here - http://php.net/manual/en/intro.sodium.php. and here - https://paragonie.com/book/pecl-libsodium/read/00-intro.md

Example PHP 7.2 sodium encryption class -

<?php

/**
 * Simple sodium crypto class for PHP >= 7.2
 * @author MRK
 */
class crypto {

    /**
     * 
     * @return type
     */
    static public function create_encryption_key() {
        return base64_encode(sodium_crypto_secretbox_keygen());
    }

    /**
     * Encrypt a message
     * 
     * @param string $message - message to encrypt
     * @param string $key - encryption key created using create_encryption_key()
     * @return string
     */
    static function encrypt($message, $key) {
        $key_decoded = base64_decode($key);
        $nonce = random_bytes(
                SODIUM_CRYPTO_SECRETBOX_NONCEBYTES
        );

        $cipher = base64_encode(
                $nonce .
                sodium_crypto_secretbox(
                        $message, $nonce, $key_decoded
                )
        );
        sodium_memzero($message);
        sodium_memzero($key_decoded);
        return $cipher;
    }

    /**
     * Decrypt a message
     * @param string $encrypted - message encrypted with safeEncrypt()
     * @param string $key - key used for encryption
     * @return string
     */
    static function decrypt($encrypted, $key) {
        $decoded = base64_decode($encrypted);
        $key_decoded = base64_decode($key);
        if ($decoded === false) {
            throw new Exception('Decryption error : the encoding failed');
        }
        if (mb_strlen($decoded, '8bit') < (SODIUM_CRYPTO_SECRETBOX_NONCEBYTES + SODIUM_CRYPTO_SECRETBOX_MACBYTES)) {
            throw new Exception('Decryption error : the message was truncated');
        }
        $nonce = mb_substr($decoded, 0, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
        $ciphertext = mb_substr($decoded, SODIUM_CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');

        $plain = sodium_crypto_secretbox_open(
                $ciphertext, $nonce, $key_decoded
        );
        if ($plain === false) {
            throw new Exception('Decryption error : the message was tampered with in transit');
        }
        sodium_memzero($ciphertext);
        sodium_memzero($key_decoded);
        return $plain;
    }

}

Sample Usage -

<?php 

$key = crypto::create_encryption_key();

$string = 'Sri Lanka is a beautiful country !';

echo $enc = crypto::encrypt($string, $key); 
echo crypto::decrypt($enc, $key);

SQL injection should not be prevented by trying to validate your input; instead, that input should be properly escaped before being passed to the database.

How to escape input totally depends on what technology you are using to interface with the database. In most cases and unless you are writing bare SQL (which you should avoid as hard as you can) it will be taken care of automatically by the framework so you get bulletproof protection for free.

You should explore this question further after you have decided exactly what your interfacing technology will be.

Create List of Single Item Repeated n Times in Python

Depending on your use-case, you want to use different techniques with different semantics.

Multiply a list for Immutable items

For immutable items, like None, bools, ints, floats, strings, tuples, or frozensets, you can do it like this:

[e] * 4

Note that this is usually only used with immutable items (strings, tuples, frozensets, ) in the list, because they all point to the same item in the same place in memory. I use this frequently when I have to build a table with a schema of all strings, so that I don't have to give a highly redundant one to one mapping.

schema = ['string'] * len(columns)

Multiply the list where we want the same item repeated

Multiplying a list gives us the same elements over and over. The need for this is rare:

[iter(iterable)] * 4

This is sometimes used to map an iterable into a list of lists:

>>> iterable = range(12)
>>> a_list = [iter(iterable)] * 4
>>> [[next(l) for l in a_list] for i in range(3)]
[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11]]

We can see that a_list contains the same range iterator four times:

>>> a_list
[<range_iterator object at 0x7fde73a5da20>, <range_iterator object at 0x7fde73a5da20>, <range_iterator object at 0x7fde73a5da20>, <range_iterator object at 0x7fde73a5da20>]

Mutable items

I've used Python for a long time now, and I have seen very few use-cases where I would do the above with mutable objects.

Instead, to get, say, a mutable empty list, set, or dict, you should do something like this:

list_of_lists = [[] for _ in columns]

The underscore is simply a throwaway variable name in this context.

If you only have the number, that would be:

list_of_lists = [[] for _ in range(4)]

The _ is not really special, but your coding environment style checker will probably complain if you don't intend to use the variable and use any other name.

Caveats for using the immutable method with mutable items:

Beware doing this with mutable objects, when you change one of them, they all change because they're all the same object:

foo = [[]] * 4
foo[0].append('x')

foo now returns:

[['x'], ['x'], ['x'], ['x']]

But with immutable objects, you can make it work because you change the reference, not the object:

>>> l = [0] * 4
>>> l[0] += 1
>>> l
[1, 0, 0, 0]

>>> l = [frozenset()] * 4
>>> l[0] |= set('abc')
>>> l
[frozenset(['a', 'c', 'b']), frozenset([]), frozenset([]), frozenset([])]

But again, mutable objects are no good for this, because in-place operations change the object, not the reference:

l = [set()] * 4
>>> l[0] |= set('abc')    
>>> l
[set(['a', 'c', 'b']), set(['a', 'c', 'b']), set(['a', 'c', 'b']), set(['a', 'c', 'b'])]

Noticed mine worked on chrome. Got it to work in Firefox by going to <about:config> and setting full-screen-api.allow-trusted-requests-only to false.

After full screen worked once, I could set that back to true, and full screen still worked which was quite perplexing.

If you don't want to use LINQ

// Get the files
DirectoryInfo info = new DirectoryInfo("path/to/files"));
FileInfo[] files = info.GetFiles();

// Sort by creation-time descending 
Array.Sort(files, delegate(FileInfo f1, FileInfo f2)
{
    return f2.CreationTime.CompareTo(f1.CreationTime);
});

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

I agree with above answers, Here is a complete read and write sample for anyone who needs it.

     router.post('/', function(req, res, next) {

        console.log(req.body);
        var id = Math.floor((Math.random()*100)+1);

        var tital = req.body.title;
        var description = req.body.description;
        var mynotes = {"Id": id, "Title":tital, "Description": description};
        
        fs.readFile('db.json','utf8', function(err,data){
            var obj = JSON.parse(data);
            obj.push(mynotes);
            var strNotes = JSON.stringify(obj);
            fs.writeFile('db.json',strNotes, function(err){
                if(err) return console.log(err);
                console.log('Note added');
            });

        })
        
        
    });


  

If you use JSON properly, you can have nested object without any issue :

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
var theUrl = "/json-handler";
xmlhttp.open("POST", theUrl);
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xmlhttp.send(JSON.stringify({ "email": "[email protected]", "response": { "name": "Tester" } }));

For an alternate crash reporting/exception tracking service check out Raygun.io - it's got a bunch of nice logic for handling Android crashes, including decent user experience when plugging it in to your app (two lines of code in your main Activity and a few lines of XML pasted into AndroidManifest).

When your app crashes, it'll automatically grab the stack trace, environment data for hard/software, user tracking info, any custom data you specify etc. It posts it to the API asynchronously so no blocking of the UI thread, and caches it to disk if there's no network available.

Disclaimer: I built the Android provider :)

Just figured out how to do this within the PDF itself - if you have acrobat pro, go to your pages tab, right click on the thumbnail for the first page, and click page properties. Click on the actions tab at the top of the window and under select trigger choose page open. Under select action choose "run a javascript". Then in the javascript window, type this:

this.print({bUI: false, bSilent: true, bShrinkToFit: true});

This will print your document without a dialogue to the default printer on your machine. If you want the print dialog, just change bUI to true, bSilent to false, and optionally, remove the shrink to fit parameter.

Auto-printing PDF!

Solved:

• Went on the log-in screen and clicked forgot my password.
• I entered my Google account email and I received a reset link.
• As you enter there a new password you'll have bitbucket id and password to use.

Sample:

git clone https://<bitbucket_id>@bitbucket.org/<repo>

In my case I had a row of Ids, and it was neccessary to cast it to char, otherwise, the result was encoded into binary format :

SELECT CAST(GROUP_CONCAT(field SEPARATOR ',') AS CHAR) FROM table

To expand on the @PostConstruct suggestion in other answers, this really is the best solution, in my opinion.

• It keeps your code decoupled from the Spring API (@PostConstruct is in javax.*)
• It explicitly annotates your init method as something that needs to be called to initialize the bean
• You don't need to remember to add the init-method attribute to your spring bean definition, spring will automatically call the method (assuming you register the annotation-config option somewhere else in the context, anyway).

Just add in the '0' in your select.

INSERT INTO table_name (a,b,c,d)
    SELECT
       other_table.a AS a,
       other_table.b AS b,
       other_table.c AS c,
       '0' AS d
    FROM other_table

You can use Array of objects and convert it to ArrayList-

Object[] array= new Object[10];
array[0]="1";
array[3]= "3";
array[2]="2";
array[7]="7";

List<Object> list= Arrays.asList(array);

ArrayList will be- [1, null, 2, 3, null, null, null, 7, null, null]

Suppose your table-size (or the number for modulo) is T = (B*C). Now if hash for your input is like (N*A*B) where N can be any integer, then your output won't be well distributed. Because every time n becomes C, 2C, 3C etc., your output will start repeating. i.e. your output will be distributed only in C positions. Note that C here is (T / HCF(table-size, hash)).

This problem can be eliminated by making HCF 1. Prime numbers are very good for that.

Another interesting thing is when T is 2^N. These will give output exactly same as all the lower N bits of input-hash. As every number can be represented powers of 2, when we will take modulo of any number with T, we will subtract all powers of 2 form number, which are >= N, hence always giving off number of specific pattern, dependent on the input. This is also a bad choice.

Similarly, T as 10^N is bad as well because of similar reasons (pattern in decimal notation of numbers instead of binary).

So, prime numbers tend to give a better distributed results, hence are good choice for table size.

You can use the following.

window.open(
  'https://google.com',
  '_blank' // <- This is what makes it open in a new window.
);

in HTML

 <button class="btn btn-success" onclick=" window.open('http://google.com','_blank')"> Google</button>

Winutils.exe is used for running the shell commands for SPARK. When you need to run the Spark without installing Hadoop, you need this file.

Steps are as follows:

1. Download the winutils.exe from following location for hadoop 2.7.1 https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin [NOTE: If you are using separate hadoop version then please download the winutils from corresponding hadoop version folder on GITHUB from the location as mentioned above.]

2. Now, create a folder 'winutils' in C:\ drive. Now create a folder 'bin' inside folder 'winutils' and copy the winutils.exe in that folder. So the location of winutils.exe will be C:\winutils\bin\winutils.exe

3. Now, open environment variable and set HADOOP_HOME=C:\winutils [NOTE: Please do not add \bin in HADOOP_HOME and no need to set HADOOP_HOME in Path]

Your issue must be resolved !!

Simple fix. Works 100%

It is not possible yet to search for content using multiple tags, for now only single tags are supported.

Firstly, the Instagram API endpoint "tags" required OAuth authentication.

This is not quite true, you only need an API-Key. Just register an application and add it to your requests. Example:

https://api.instagram.com/v1/users/userIdYouWantToGetMediaFrom/media/recent?client_id=yourAPIKey

Also note that the username is not the user-id. You can look up user-Id`s here.

A workaround for searching multiple keywords would be if you start one request for each tag and compare the results on your server. Of course this could slow down your site depending on how much keywords you want to compare.
