With the directory parameter:

impdp system/password@$ORACLE_SID schemas=USER_SCHEMA directory=MY_DIR \
  dumpfile=mydumpfile.dmp logfile=impdpmydumpfile.log

The default directory is DATA_PUMP_DIR, which is presumably set to /u01/app/oracle/admin/mydatabase/dpdump on your system.

To use a different directory you (or your DBA) will have to create a new directory object in the database, which points to the Oracle-visible operating system directory you put the file into, and assign privileges to the user doing the import.

Use filter, or if the number of dictionaries in exampleSet is too high, use ifilter of the itertools module. It would return an iterator, instead of filling up your system's memory with the entire list at once:

from itertools import ifilter
for elem in ifilter(lambda x: x['type'] in keyValList, exampleSet):
    print elem

The .import command is a feature of the sqlite3 command-line tool. To do it in Python, you should simply load the data using whatever facilities Python has, such as the csv module, and inserting the data as per usual.

This way, you also have control over what types are inserted, rather than relying on sqlite3's seemingly undocumented behaviour.

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

I'd like to contribute with one common scenario (in Python 3) and explore a few approaches to it.

The built-in function open() accepts either relative or absolute path as its first argument. The relative path is treated as relative to the current working directory though so it is recommended to pass the absolute path to the file.

Simply said, if you run a script file with the following code, it is not guaranteed that the example.txt file will be created in the same directory where the script file is located:

with open('example.txt', 'w'):
    pass

To fix this code we need to get the path to the script and make it absolute. To ensure the path to be absolute we simply use the os.path.realpath() function. To get the path to the script there are several common functions that return various path results:

• os.getcwd()
• os.path.realpath('example.txt')
• sys.argv[0]
• __file__

Both functions os.getcwd() and os.path.realpath() return path results based on the current working directory. Generally not what we want. The first element of the sys.argv list is the path of the root script (the script you run) regardless of whether you call the list in the root script itself or in any of its modules. It might come handy in some situations. The __file__ variable contains path of the module from which it has been called.

The following code correctly creates a file example.txt in the same directory where the script is located:

filedir = os.path.dirname(os.path.realpath(__file__))
filepath = os.path.join(filedir, 'example.txt')

with open(filepath, 'w'):
    pass

var isDate_ = function(input) {
        var status = false;
        if (!input || input.length <= 0) {
          status = false;
        } else {
          var result = new Date(input);
          if (result == 'Invalid Date') {
            status = false;
          } else {
            status = true;
          }
        }
        return status;
      }

You have a lot of type-mismatches in your code such as trying to put an int value where BigDecimal is required. The corrected version of your code:

public class Payment
{
    BigDecimal itemCost  = BigDecimal.ZERO;
    BigDecimal totalCost = BigDecimal.ZERO;

    public BigDecimal calculateCost(int itemQuantity, BigDecimal itemPrice)
    {
        itemCost  = itemPrice.multiply(new BigDecimal(itemQuantity));
        totalCost = totalCost.add(itemCost);
        return totalCost;
    }
}

[^,;]+         

You haven't specified the regex implementation you are using. Most of them have a Split method that takes delimiters and split by them. You might want to use that one with a "normal" (without ^) character class:

[,;]+

If you're talking MS SQL, here's the most efficient way. This retrieves the current identity seed from a table based on whatever column is the identity.

select IDENT_CURRENT('TableName') as LastIdentity

Using MAX(id) is more generic, but for example I have an table with 400 million rows that takes 2 minutes to get the MAX(id). IDENT_CURRENT is nearly instantaneous...

The man page explains that you can enter command line mode in a running session by typing Ctrl+A, :, then issuing the scrollback <num> command.

Got stuck as I was trying to a go get ... I think it was related to git. Here is how was able to fix it ...

1. I entered the following in terminal:

   sudo xcodebuild -license
   

2. This will open the agreement. Go all the way to end and type "agree".

That takes care of go get issues.

It was quite interesting how unrelated things were.

This one worked for me getBaseContext();

Maybe a little late to reply. I happen to run into the same problem today. I find that on Windows you can change the console encoder to utf-8 or other encoder that can represent your data. Then you can print it to sys.stdout.

First, run following code in the console:

chcp 65001
set PYTHONIOENCODING=utf-8

Then, start python do anything you want.

You dont have to compile it. the first you use it (import) it is compiled by the CPython interpreter. But if you really want to compile there are several options.

To compile to exe

• py2exe
• cx_Freeze
• py2app

Or 2 compile just a specific *.py file, you can just use

import py_compile
py_compile.compile("yourpythoncode.py")

It breaks semantics, that's all. It works fine, but there may be screen readers or something down the road that won't enjoy processing your HTML if you "break semantics".

You've got a few things going on there. One, why a class? Do you actually have multiple of these on the page? The CSS suggests you can't. If not you should use an ID - it's faster to select both in CSS and jQuery:

<div id=bottomMenu>You read it all.</div>

Second you've got a few crazy things going on in that CSS - in particular the z-index is supposed to just be a number, not measured in pixels. It specifies what layer this tag is on, where each higher number is closer to the user (or put another way, on top of/occluding tags with lower z-indexes).

The animation you're trying to do is basically .fadeIn(), so just set the div to display: none; initially and use .fadeIn() to animate it:

$('#bottomMenu').fadeIn(2000);

.fadeIn() works by first doing display: (whatever the proper display property is for the tag), opacity: 0, then gradually ratcheting up the opacity.

Full working example:

http://jsfiddle.net/b9chris/sMyfT/

CSS:

#bottomMenu {
    display: none;
    position: fixed;
    left: 0; bottom: 0;
    width: 100%; height: 60px;
    border-top: 1px solid #000;
    background: #fff;
    z-index: 1;
}

JS:

var $win = $(window);

function checkScroll() {
    if ($win.scrollTop() > 100) {
        $win.off('scroll', checkScroll);
        $('#bottomMenu').fadeIn(2000);
    }
}

$win.scroll(checkScroll);

None of these solutions worked for me. I had a tangle of Nuget packages that couldn't update because of circular dependencies on each other.

I would up having to fix this the old-fashioned way. I created a new MVC/web api project and manually copied System.Web.Http and System.Web.Http.WebHost from the new project into the Nuget folders of the exisitng solution. From there I updated the references by, OMG, "browsing" and fixed the problem.

Short Answer:

• npm install honors package-lock.json only if it satisfies the requirements of package.json.
• If it doesn't satisfy those requirements, packages are updated & package-lock is overwritten.
• If you want the install to fail instead of overwriting package-lock when this happens, use npm ci.

Here is a scenario that might explain things (Verified with NPM 6.3.0)

You declare a dependency in package.json like:

"depA": "^1.0.0"

Then you do, npm install which will generate a package-lock.json with:

"depA": "1.0.0"

Few days later, a newer minor version of "depA" is released, say "1.1.0", then the following holds true:

npm ci       # respects only package-lock.json and installs 1.0.0

npm install  # also, respects the package-lock version and keeps 1.0.0 installed 
             # (i.e. when package-lock.json exists, it overrules package.json)

Next, you manually update your package.json to:

"depA": "^1.1.0"

Then rerun:

npm ci      # will try to honor package-lock which says 1.0.0
            # but that does not satisfy package.json requirement of "^1.1.0" 
            # so it would throw an error 

npm install # installs "1.1.0" (as required by the updated package.json)
            # also rewrites package-lock.json version to "1.1.0"
            # (i.e. when package.json is modified, it overrules the package-lock.json)

1. If your source and target database resides in the same local machine, you can use:

Note:- Sourcedb already exists in your database.

CREATE DATABASE targetdb WITH TEMPLATE sourcedb;

This statement copies the sourcedb to the targetdb.

2. If your source and target databases resides on different servers, you can use following steps:

Step 1:- Dump the source database to a file.

pg_dump -U postgres -O sourcedb sourcedb.sql

Note:- Here postgres is the username so change the name accordingly.

Step 2:- Copy the dump file to the remote server.

Step 3:- Create a new database in the remote server

CREATE DATABASE targetdb;

Step 4:- Restore the dump file on the remote server

psql -U postgres -d targetdb -f sourcedb.sql

(pg_dump is a standalone application (i.e., something you run in a shell/command-line) and not an Postgres/SQL command.)

This should do it.

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles

.modal {
    display: block;
}
.modal-body:before,
.modal-body:after {
    display: table;
    content: " ";
}
.modal-header:before,
.modal-header:after {
    display: table;
    content: " ";
}

(The last ones are necessary if you use custom directives) and encapsulate the html with

<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <h4 class="modal-title">Modal title</h4>
    </div>
    <div class="modal-body">
      ...
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      <button type="button" class="btn btn-primary">Save changes</button>
    </div>
  </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

In Chrome, right click in the console and check 'preserve log on navigation'.

I use https://github.com/yabawock/bootstrap-sass-rails

Which is pretty much straight forward install, fast gem updates and followups and quick fixes in case is needed.

You can pipe grep result to head in conjunction with stdbuf.

Note, that in order to ensure stopping after Nth match, you need to using stdbuf to make sure grep don't buffer its output:

stdbuf -oL grep -rl 'pattern' * | head -n1
stdbuf -oL grep -o -a -m 1 -h -r "Pulsanti Operietur" /path/to/dir | head -n1
stdbuf -oL grep -nH -m 1 -R "django.conf.urls.defaults" * | head -n1

As soon as head consumes 1 line, it terminated and grep will receive SIGPIPE because it still output something to pipe while head was gone.

This assumed that no file names contain newline.

Plug and Play Solution - Xcode 9

Autolayout just like UILabel, with the link detection, text selection, editing and scrolling of UITextView.

Automatically handles

• Safe area
• Content insets
• Line fragment padding
• Text container insets
• Constraints
• Stack views
• Attributed strings
• Whatever.

A lot of these answers got me 90% there, but none were fool-proof.

Drop in this UITextView subclass and you're good.

If this isn't made obvious by the the previous answers:

:bd will close the current buffer. If you don't want to grab the buffer list.

The PropertiesPlaceholderConfigurer bean has an alternative property called "propertiesArray". Use this instead of the "properties" property, and configure it with an <array> of property references.

The following code snippet is doing it for me (lat and lng are doubles declared above this bit):

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);

I had SESSION_SECURE_COOKIE set to true so my dev environment didn't work when logging in, so I added SESSION_SECURE_COOKIE=false to my dev .env file and all works fine my mistake was changing the session.php file instead of adding the variable to the .env file.

You can create a surface with text on it. For this take a look at this short example:

pygame.font.init() # you have to call this at the start, 
                   # if you want to use this module.
myfont = pygame.font.SysFont('Comic Sans MS', 30)

This creates a new object on which you can call the render method.

textsurface = myfont.render('Some Text', False, (0, 0, 0))

This creates a new surface with text already drawn onto it. At the end you can just blit the text surface onto your main screen.

screen.blit(textsurface,(0,0))

Bear in mind, that everytime the text changes, you have to recreate the surface again, to see the new text.

You need to use a <br> because your Content-Type is text/html.

It works without the Content-Type header because then your e-mail will be interpreted as plain text. If you really want to use \n you should use Content-Type: text/plain but then you'll lose any markup.

Also check out similar question here.

Previous answers are correct but here is one more way of doing this and some tips:

Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there

Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh

things to watch for /tips:

• Environment variables, if your job is running at the same time then you need to worry about concurrency issues. One job may be setting the value of environment variables and the next may use the value or take some action based on that incorrectly.
• Make sure all paths are fully qualified
• Think about logging /var/log or somewhere so you would also have something to go to on the server (optional)
• thing about space issue and permissions, running out of space and permission issues are very common in linux environment
• Alerting and make sure your script/job fails the jenkin jobs when your script fails

The Web Developer Toolbar has an option to disable caching which makes it very easy to turn it on and off when you need it.

Above answers were helpful, but for unknown reasons they did not seem to work. So if you have already installed MySql workbench on your system, instead of downloading the jar files and struggling with the correct version just go to

C:\Program Files (x86)\MySQL\Connector J 8.0

and copy mysql-connector-java-8.0.12 (does not matter what version it is) the jar file in that location and paste it to C:\Program Files\pentaho\design-tools\data-integration\lib

I think this simply demonstrates what you are trying to achieve:

# coding: utf-8

class Class():
    count = 0
    names = []

    def __init__(self,name):
        self.number = Class.count
        self.name = name
        Class.count += 1
        Class.names.append(name)

l=[]
l.append(Class("uno"))
l.append(Class("duo"))
print l
print l[0].number, l[0].name
print l[1].number, l[1].name
print Class.count, Class.names

Run the code above and you get:-

[<__main__.Class instance at 0x6311b2c>, 
<__main__.Class instance at 0x63117ec>]
0 uno
1 duo
2 ['uno', 'duo']

After some time with the same disturbing error and after I write a unique Bundle Identifier and it didn't help, I searched the web and found here that my error was that I selected a virtual device and not an real device. The solution was:

1.I plugged my iPhone

2.I clicked on the button - set the active scheme. and there it was on the top - device iPhone. the error has gone.

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

An addition to previous answers, to use Request.Params["__EVENTTARGET"] you have to set the option:

buttonName.UseSubmitBehavior = false;

Use config.to_prepare to load you monkey patches/extensions for every request in development mode.

config.to_prepare do |action_dispatcher|
 # More importantly, will run upon every request in development, but only once (during boot-up) in production and test.
 Rails.logger.info "\n--- Loading extensions for #{self.class} "
 Dir.glob("#{Rails.root}/lib/extensions/**/*.rb").sort.each do |entry|
   Rails.logger.info "Loading extension(s): #{entry}"
   require_dependency "#{entry}"
 end
 Rails.logger.info "--- Loaded extensions for #{self.class}\n"

end

My answer differs slightly to @FlavorScape in that I had a single (default export) function in the imported module, I did the following:

import * as functionToTest from 'whatever-lib';

const fooSpy = spyOn(functionToTest, 'default');

An Iterator moves forward only, if it read it once, it's done. Your

m.get(itr2.next());

is reading the next value of itr2.next();, that is why you are missing a few (actually not a few, every other) keys.

You can perform bulk insert using mongoose, as the highest score answer. But the example cannot work, it should be:

/* a humongous amount of potatos */
var potatoBag = [{name:'potato1'}, {name:'potato2'}];

var Potato = mongoose.model('Potato', PotatoSchema);
Potato.collection.insert(potatoBag, onInsert);

function onInsert(err, docs) {
    if (err) {
        // TODO: handle error
    } else {
        console.info('%d potatoes were successfully stored.', docs.length);
    }
}

Don't use a schema instance for the bulk insert, you should use a plain map object.

This is a little library that should help you with hexadecimals in Java: https://github.com/PatrykSitko/HEX4J

It can convert from and to hexadecimals. It supports:

• byte
• boolean
• char
• char[]
• String
• short
• int
• long
• float
• double (signed and unsigned)

With it, you can convert your String to hexadecimal and the hexadecimal to a float/double.

Example:

String hexValue = HEX4J.Hexadecimal.from.String("Hello World");
double doubleValue = HEX4J.Hexadecimal.to.Double(hexValue);

In case someone is using swagger:

Change the Scheme to HTTP or HTTPS, depend on needs, prior to hit the execute.

Size of some float types may exceed the size of int. This example shows a safe conversion of any float type to int using the int safeFloatToInt(const FloatType &num); function:

#include <iostream>
#include <limits>
using namespace std;

template <class FloatType>
int safeFloatToInt(const FloatType &num) {
   //check if float fits into integer
   if ( numeric_limits<int>::digits < numeric_limits<FloatType>::digits) {
      // check if float is smaller than max int
      if( (num < static_cast<FloatType>( numeric_limits<int>::max())) &&
          (num > static_cast<FloatType>( numeric_limits<int>::min())) ) {
         return static_cast<int>(num); //safe to cast
      } else {
        cerr << "Unsafe conversion of value:" << num << endl;
        //NaN is not defined for int return the largest int value
        return numeric_limits<int>::max();
      }
   } else {
      //It is safe to cast
      return static_cast<int>(num);
   }
}
int main(){
   double a=2251799813685240.0;
   float b=43.0;
   double c=23333.0;
   //unsafe cast
   cout << safeFloatToInt(a) << endl;
   cout << safeFloatToInt(b) << endl;
   cout << safeFloatToInt(c) << endl;
   return 0;
}

Result:

Unsafe conversion of value:2.2518e+15

Try this :

   for match in re.finditer(r"\[P[^\]]*\](.*?)\[/P\]", subject):

        # matched text: match.group()

here's a way using the SSSE3 instruction pshufb using its Intel intrinsic, assuming you have a multiple of 4 ints:

unsigned int *bswap(unsigned int *destination, unsigned int *source, int length) {
    int i;
    __m128i mask = _mm_set_epi8(12, 13, 14, 15, 8, 9, 10, 11, 4, 5, 6, 7, 0, 1, 2, 3);
    for (i = 0; i < length; i += 4) {
        _mm_storeu_si128((__m128i *)&destination[i],
        _mm_shuffle_epi8(_mm_loadu_si128((__m128i *)&source[i]), mask));
    }
    return destination;
}

Sorry that this is very late, but I just was looking at this question and found something that worked for me. I went to PROJECT->Build Settings and found the Code Signing section. Beside debug, my distribution profile that said Iphone Distribution: MY NAME was selected. I instead selected Iphone Developer: MY NAME on the drop-down list under IpodProfile (for bundle identifiers com.myName.myApp which was the provisioning Profile for my device. Hope this helps!

I used a hidden checkbox to persistent view of some message. The checkbox could be hidden (display:none) or not. This is a tiny code that I could write.

int id = getResources().getIdentifier("gameover", "drawable", getPackageName());
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams vp = 
    new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                    LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(vp);        
imageView.setImageResource(id);        
someLinearLayout.addView(imageView); 

public static void replaceFileString(String old, String new) throws IOException {
    String fileName = Settings.getValue("fileDirectory");
    FileInputStream fis = new FileInputStream(fileName);
    String content = IOUtils.toString(fis, Charset.defaultCharset());
    content = content.replaceAll(old, new);
    FileOutputStream fos = new FileOutputStream(fileName);
    IOUtils.write(content, new FileOutputStream(fileName), Charset.defaultCharset());
    fis.close();
    fos.close();
}

above is my implementation of Meriton's example that works for me. The fileName is the directory (ie. D:\utilities\settings.txt). I'm not sure what character set should be used, but I ran this code on a Windows XP machine just now and it did the trick without doing that temporary file creation and renaming stuff.

The Functional Java library has an array wrapper class that equips arrays with handy methods like concatenation.

import static fj.data.Array.array;

...and then

Array<String> both = array(first).append(array(second));

To get the unwrapped array back out, call

String[] s = both.array();

Use \overset{above}{main} in math mode. In your case, \overset{a}{\#}.

For gcc you want to omit any -O1 -O2 or -O3 options passed to the compiler or if you already have them you can append the -O0 option to turn it off again. It might also help you to add -g for debug so that you can see the c source and disassembled machine code in your debugger.

See also: http://sourceware.org/gdb/onlinedocs/gdb/Optimized-Code.html

You can specify the -t option (--target) to specify the destination directory. See pip install --help for detailed information. This is the command you need:

pip install -t path_to_your_home package-name

for example, for installing say mxnet, in my $HOME directory, I type:

pip install -t /home/foivos/ mxnet

We can use pip freeze to get any Python package version without opening the Python shell.

pip freeze | grep 'numpy'

Instead of "w" use "a" (append) mode with open function:

with open("games.txt", "a") as text_file:

This is how you do it

SELECT ID,NAME, (C_COUNTS+F_COUNTS) AS SUM_COUNTS 
FROM TABLE 
ORDER BY SUM_COUNTS LIMIT 20

The SUM function will add up all rows, so the order by clause is useless, instead you will have to use the group by clause.

Miguel Sanchez's response is the way it should be. The other way executing Rscript could be 'env' command to run the system wide RScript.

#!/usr/bin/env Rscript

Like Uri Cohen's answer, but is a generator instead. Will start by using colors far apart. Deterministic.

Sample, left colors first:

Another example of the same concept - but say - you have 2 different columns - and you want to apply different agg functions to each of them i.e

f.groupBy("col1").agg(sum("col2").alias("col2"), avg("col3").alias("col3"), ...)

Here is the way to achieve it - though I do not yet know how to add the alias in this case

See the example below - Using Maps

val Claim1 = StructType(Seq(StructField("pid", StringType, true),StructField("diag1", StringType, true),StructField("diag2", StringType, true), StructField("allowed", IntegerType, true), StructField("allowed1", IntegerType, true)))
val claimsData1 = Seq(("PID1", "diag1", "diag2", 100, 200), ("PID1", "diag2", "diag3", 300, 600), ("PID1", "diag1", "diag5", 340, 680), ("PID2", "diag3", "diag4", 245, 490), ("PID2", "diag2", "diag1", 124, 248))

val claimRDD1 = sc.parallelize(claimsData1)
val claimRDDRow1 = claimRDD1.map(p => Row(p._1, p._2, p._3, p._4, p._5))
val claimRDD2DF1 = sqlContext.createDataFrame(claimRDDRow1, Claim1)

val l = List("allowed", "allowed1")
val exprs = l.map((_ -> "sum")).toMap
claimRDD2DF1.groupBy("pid").agg(exprs) show false
val exprs = Map("allowed" -> "sum", "allowed1" -> "avg")

claimRDD2DF1.groupBy("pid").agg(exprs) show false

Are you sure that all the lines have at least 2 columns? Can you try something like, just to check?:

sc.textFile("file.csv") \
    .map(lambda line: line.split(",")) \
    .filter(lambda line: len(line)>1) \
    .map(lambda line: (line[0],line[1])) \
    .collect()

Alternatively, you could print the culprit (if any):

sc.textFile("file.csv") \
    .map(lambda line: line.split(",")) \
    .filter(lambda line: len(line)<=1) \
    .collect()

in my case (under ubuntu 18.04), I have mixed $( ${} ) that works fine:

BACKUPED_NB=$(ls ${HOST_BACKUP_DIR}*${CONTAINER_NAME}.backup.sql.gz | wc --lines)

full example here.

It's quite easy, actually. You can use the System.IO.Directory class in conjunction with System.IO.Path. Something like (using LINQ makes it even easier):

var allFilenames = Directory.EnumerateFiles(path).Select(p => Path.GetFileName(p));

// Get all filenames that have a .txt extension, excluding the extension
var candidates = allFilenames.Where(fn => Path.GetExtension(fn) == ".txt")
                             .Select(fn => Path.GetFileNameWithoutExtension(fn));

There are many variations on this technique too, of course. Some of the other answers are simpler if your filter is simpler. This one has the advantage of the delayed enumeration (if that matters) and more flexible filtering at the expense of more code.

Oh my. This is actually so simple!

grouped = df3.groupby(level=0)
df4 = grouped.last()
df4
                      A   B  rownum

2001-01-01 05:00:00   5   5       5

Follow up edit 2013-10-29 In the case where I have a fairly complex MultiIndex, I think I prefer the groupby approach. Here's simple example for posterity:

import numpy as np
import pandas

# fake index
idx = pandas.MultiIndex.from_tuples([('a', letter) for letter in list('abcde')])

# random data + naming the index levels
df1 = pandas.DataFrame(np.random.normal(size=(5,2)), index=idx, columns=['colA', 'colB'])
df1.index.names = ['iA', 'iB']

# artificially append some duplicate data
df1 = df1.append(df1.select(lambda idx: idx[1] in ['c', 'e']))
df1
#           colA      colB
#iA iB                    
#a  a  -1.297535  0.691787
#   b  -1.688411  0.404430
#   c   0.275806 -0.078871
#   d  -0.509815 -0.220326
#   e  -0.066680  0.607233
#   c   0.275806 -0.078871  # <--- dup 1
#   e  -0.066680  0.607233  # <--- dup 2

and here's the important part

# group the data, using df1.index.names tells pandas to look at the entire index
groups = df1.groupby(level=df1.index.names)  
groups.last() # or .first()
#           colA      colB
#iA iB                    
#a  a  -1.297535  0.691787
#   b  -1.688411  0.404430
#   c   0.275806 -0.078871
#   d  -0.509815 -0.220326
#   e  -0.066680  0.607233

I ran into this issue with Python 3.6 and Python 3.7. The top answer (running pip install --upgrade pip enum34) did not solve the problem.

I don't know why, but the reason why this error happen is because enum.py was missing from .venv/myvenv/lib/python3.7/.

But the file was in /usr/lib/python3.7/.

Following this answer, I just created the symbolic link by myself :

ln -s /usr/lib/python3.7/enum.py .venv/myvenv/lib/python3.7/enum.py

You could set your channel to nil in addition to closing it. That way you can check if it is nil.

example in the playground: https://play.golang.org/p/v0f3d4DisCz

edit: This is actually a bad solution as demonstrated in the next example, because setting the channel to nil in a function would break it: https://play.golang.org/p/YVE2-LV9TOp

Let me clarify what you're talking about: you want to test Foo in a testcase, which calls external method uses_some_other_method. Instead of calling the actual method, you want to mock the return value.

class Foo:
    def method_1():
       results = uses_some_other_method()
    def method_n():
       results = uses_some_other_method()

Suppose the above code is in foo.py and uses_some_other_method is defined in module bar.py. Here is the unittest:

import unittest
import mock

from foo import Foo


class TestFoo(unittest.TestCase):

    def setup(self):
        self.foo = Foo()

    @mock.patch('foo.uses_some_other_method')
    def test_method_1(self, mock_method):
        mock_method.return_value = 3
        self.foo.method_1(*args, **kwargs)

        mock_method.assert_called_with(*args, **kwargs)

If you want to change the return value every time you passed in different arguments, mock provides side_effect.

This is just torazaburo's answer, updated to use a MouseEvent object.

function click(x, y)
{
    var ev = new MouseEvent('click', {
        'view': window,
        'bubbles': true,
        'cancelable': true,
        'screenX': x,
        'screenY': y
    });

    var el = document.elementFromPoint(x, y);

    el.dispatchEvent(ev);
}

You want to do #include <string> instead of string.h and then the type string lives in the std namespace, so you will need to use std::string to refer to it.

After reading @MLProgrammer-CiM's answer, here is my code:

class NormalViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

    @Bind(R.id.card_item_normal)
    CardView cardView;

    public NormalViewHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this, itemView);
        cardView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if(v instanceof CardView) {
            // use getAdapterPosition() instead of getLayoutPosition()
            int itemPosition = getAdapterPosition();
            removeItem(itemPosition);
        }
    }
}

I got this completely worthless and uninformative error when I tried to:

ALTER TABLE `comments` ADD CONSTRAINT FOREIGN KEY (`user_id`) REFERENCES `users` (`id`) ON DELETE SET NULL ON UPDATE CASCADE;

My problem was in my comments table, user_id was defined as:

`user_id` int(10) unsigned NOT NULL

So... in my case, the problem was with the conflict between NOT NULL, and ON DELETE SET NULL.

json characters are nothing special when it comes down to storage, chars such as

{,},[,],',a-z,0-9.... are really nothing special and can be stored as text.

the first problem your going to have is this

{ profile_id: 22, username: 'Robert', password: 'skhgeeht893htgn34ythg9er' }

that stored in a database is not that simple to update unless you had your own proceedure and developed a jsondecode for mysql

UPDATE users SET JSON(user_data,'username') = 'New User';

So as you cant do that you would Have to first SELECT the json, Decode it, change it, update it, so in theory you might as well spend more time constructing a suitable database structure!

I do use json to store data but only Meta Data, data that dont get updated often, not related to the user specific.. example if a user adds a post, and in that post he adds images ill parse the images and create thumbs and then use the thumb urls in a json format.

You are not returning a response object from your view my_form_post. The function ends with implicit return None, which Flask does not like.

Make the function my_form_post return an explicit response, for example

return 'OK'

at the end of the function.

Here's a controversial option:

String.prototype.includesOneOf = function(arrayOfStrings) {
  if(!Array.isArray(arrayOfStrings)) {
    throw new Error('includesOneOf only accepts an array')
  }
  return arrayOfStrings.some(str => this.includes(str))
}

Allowing you to do things like:

'Hi, hope you like this option'.toLowerCase().includesOneOf(["hello", "hi", "howdy"]) // True

For Picrofo EDY

It depends, if you use the ShowDialog() as a way of showing your form and to close it you use the close button instead of this.Close(). The form will not be disposed or destroyed, it will only be hidden and changes can be made after is gone. In order to properly close it you will need the Dispose() or Close() method. In the other hand, if you use the Show() method and you close it, the form will be disposed and can not be modified after.

Displaying an Image in WPF is much easier than that. Try this:

<Image Source="{Binding DisplayedImagePath}" HorizontalAlignment="Left" 
    Margin="0,0,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Bottom" 
    Grid.Row="8" Width="200"  Grid.ColumnSpan="2" />

And the property can just be a string:

public string DisplayedImage 
{
    get { return @"C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg"; }
}

Although you really should add your images to a folder named Images in the root of your project and set their Build Action to Resource in the Properties Window in Visual Studio... you could then access them using this format:

public string DisplayedImage 
{
    get { return "/AssemblyName;component/Images/ImageName.jpg"; }
}

UPDATE >>>

As a final tip... if you ever have a problem with a control not working as expected, simply type 'WPF', the name of that control and then the word 'class' into a search engine. In this case, you would have typed 'WPF Image Class'. The top result will always be MSDN and if you click on the link, you'll find out all about that control and most pages have code examples as well.

UPDATE 2 >>>

If you followed the examples from the link to MSDN and it's not working, then your problem is not the Image control. Using the string property that I suggested, try this:

<StackPanel>
    <Image Source="{Binding DisplayedImagePath}" />
    <TextBlock Text="{Binding DisplayedImagePath}" />
</StackPanel>

If you can't see the file path in the TextBlock, then you probably haven't set your DataContext to the instance of your view model. If you can see the text, then the problem is with your file path.

UPDATE 3 >>>

In .NET 4, the above Image.Source values would work. However, Microsoft made some horrible changes in .NET 4.5 that broke many different things and so in .NET 4.5, you'd need to use the full pack path like this:

<Image Source="pack://application:,,,/AssemblyName;component/Images/image_to_use.png">

For further information on pack URIs, please see the Pack URIs in WPF page on Microsoft Docs.

It still needs to be perfected but it's a god solution for a centralized URI system :D

Check your error log file and then use the tail command as:

tail -200f /var/log/redis_6379.log

or

 tail -200f /var/log/redis.log

According to your error file name..

First, follow the instructions in this question to squash everything to a single commit. Then make a forced push to the remote:

$ git push origin +master

And optionally delete all other branches both locally and remotely:

$ git push origin :<branch>
$ git branch -d <branch>

Try the below,

1. Close android studio
2. Then delete .iml , .idea files
3. Open again the android studio
4. Sync with Gradle.

In this link, we will find the solution Link.

System.out is a PrintStream, and in itself does not provide any way to modify what gets output. Depending on what is backing that object, you may or may not be able to modify it. For example, if you are redirecting System.out to a log file, you may be able to modify that file after the fact. If it's going straight to a console, the text will disappear once it reaches the top of the console's buffer, but there's no way to mess with it programmatically.

I'm not sure exactly what you're hoping to accomplish, but you may want to consider creating a proxy PrintStream to filter messages as they get output, instead of trying to remove them after the fact.

See the UIScreen Reference: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIScreen_Class/Reference/UIScreen.html

if([[UIScreen mainScreen] respondsToSelector:NSSelectorFromString(@"scale")])
{
    if ([[UIScreen mainScreen] scale] < 1.1)
        NSLog(@"Standard Resolution Device");

    if ([[UIScreen mainScreen] scale] > 1.9)
        NSLog(@"High Resolution Device");
}

Create a Directive with the show and size attributes ( you can add more also )

    app.directive('loader',function(){
    return {
    restrict:'EA',
    scope:{
        show : '@',
      size : '@'
    },
    template : '<div class="loader-container"><div class="loader" ng-if="show" ng-class="size"></div></div>'
  }
})

and in html use as

 <loader show="{{loader1}}" size="sm"></loader>

In the show variable pass true when any promise is running and make that false when request is completed. Active demo - Angular Loader directive example demo in JsFiddle

In our code we have a specific validator inherited from the BaseValidator class.

This class does the following:

1. Validates the e-mail address against a regular expression.
2. Does a lookup on the MX record for the domain to make sure there is at least a server to deliver to.

This is the closest you can get to validation without actually sending the person an e-mail confirmation link.

Necromancing.
The provided answers are incomplete.

First, as already said, you cannot add multiple allow-from hosts, that's not supported.
Second, you need to dynamically extract that value from the HTTP referrer, which means that you can't add the value to Web.config, because it's not always the same value.

It will be necessary to do browser-detection to avoid adding allow-from when the browser is Chrome (it produces an error on the debug - console, which can quickly fill the console up, or make the application slow). That also means you need to modify the ASP.NET browser detection, as it wrongly identifies Edge as Chrome.

This can be done in ASP.NET by writing a HTTP-module which runs on every request, that appends a http-header for every response, depending on the request's referrer. For Chrome, it needs to add Content-Security-Policy.

You need to register the context_EndRequest function in the HTTP-module Init function.

public class RequestLanguageChanger : System.Web.IHttpModule
{


    void System.Web.IHttpModule.Dispose()
    {
        // throw new NotImplementedException();
    }


    void System.Web.IHttpModule.Init(System.Web.HttpApplication context)
    {
        // https://stackoverflow.com/questions/441421/httpmodule-event-execution-order
        context.EndRequest += new System.EventHandler(context_EndRequest);
    }

    // context_EndRequest Code from above comes here


}

Next you need to add the module to your application. You can either do this programmatically in Global.asax by overriding the Init function of the HttpApplication, like this:

namespace ChangeRequestLanguage
{


    public class Global : System.Web.HttpApplication
    {

        System.Web.IHttpModule mod = new libRequestLanguageChanger.RequestLanguageChanger();

        public override void Init()
        {
            mod.Init(this);
            base.Init();
        }



        protected void Application_Start(object sender, System.EventArgs e)
        {

        }

        protected void Session_Start(object sender, System.EventArgs e)
        {

        }

        protected void Application_BeginRequest(object sender, System.EventArgs e)
        {

        }

        protected void Application_AuthenticateRequest(object sender, System.EventArgs e)
        {

        }

        protected void Application_Error(object sender, System.EventArgs e)
        {

        }

        protected void Session_End(object sender, System.EventArgs e)
        {

        }

        protected void Application_End(object sender, System.EventArgs e)
        {

        }


    }


}

or you can add entries to Web.config if you don't own the application source-code:

      <httpModules>
        <add name="RequestLanguageChanger" type= "libRequestLanguageChanger.RequestLanguageChanger, libRequestLanguageChanger" />
      </httpModules>
    </system.web>

  <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>

    <modules runAllManagedModulesForAllRequests="true">
      <add name="RequestLanguageChanger" type="libRequestLanguageChanger.RequestLanguageChanger, libRequestLanguageChanger" />
    </modules>
  </system.webServer>
</configuration>

The entry in system.webServer is for IIS7+, the other in system.web is for IIS 6.
Note that you need to set runAllManagedModulesForAllRequests to true, for that it works properly.

The string in type is in the format "Namespace.Class, Assembly". Note that if you write your assembly in VB.NET instead of C#, VB creates a default-Namespace for each project, so your string will look like

"[DefaultNameSpace.Namespace].Class, Assembly"

If you want to avoid this problem, write the DLL in C#.

If you want this to be handled by UILabel and not UITextView, you can make UILabel subclass, like this one:

class LinkedLabel: UILabel {

fileprivate let layoutManager = NSLayoutManager()
fileprivate let textContainer = NSTextContainer(size: CGSize.zero)
fileprivate var textStorage: NSTextStorage?


override init(frame aRect:CGRect){
    super.init(frame: aRect)
    self.initialize()
}

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

func initialize(){

    let tap = UITapGestureRecognizer(target: self, action: #selector(LinkedLabel.handleTapOnLabel))
    self.isUserInteractionEnabled = true
    self.addGestureRecognizer(tap)
}

override var attributedText: NSAttributedString?{
    didSet{
        if let _attributedText = attributedText{
            self.textStorage = NSTextStorage(attributedString: _attributedText)

            self.layoutManager.addTextContainer(self.textContainer)
            self.textStorage?.addLayoutManager(self.layoutManager)

            self.textContainer.lineFragmentPadding = 0.0;
            self.textContainer.lineBreakMode = self.lineBreakMode;
            self.textContainer.maximumNumberOfLines = self.numberOfLines;
        }

    }
}

func handleTapOnLabel(tapGesture:UITapGestureRecognizer){

    let locationOfTouchInLabel = tapGesture.location(in: tapGesture.view)
    let labelSize = tapGesture.view?.bounds.size
    let textBoundingBox = self.layoutManager.usedRect(for: self.textContainer)
    let textContainerOffset = CGPoint(x: ((labelSize?.width)! - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x, y: ((labelSize?.height)! - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y)

    let locationOfTouchInTextContainer = CGPoint(x: locationOfTouchInLabel.x - textContainerOffset.x, y: locationOfTouchInLabel.y - textContainerOffset.y)
    let indexOfCharacter = self.layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: self.textContainer, fractionOfDistanceBetweenInsertionPoints: nil)


    self.attributedText?.enumerateAttribute(NSLinkAttributeName, in: NSMakeRange(0, (self.attributedText?.length)!), options: NSAttributedString.EnumerationOptions(rawValue: UInt(0)), using:{
        (attrs: Any?, range: NSRange, stop: UnsafeMutablePointer<ObjCBool>) in

        if NSLocationInRange(indexOfCharacter, range){
            if let _attrs = attrs{

                UIApplication.shared.openURL(URL(string: _attrs as! String)!)
            }
        }
    })

}}

After various attempt, only this works well for me (under ios 8):

NSURLCache *cache = [[NSURLCache alloc] initWithMemoryCapacity:1 diskCapacity:1 diskPath:nil];
[NSURLCache setSharedURLCache:cache];

$(element).click(function(){
    window.close();
});

Note: you can not close any window that you didn't opened with window.open. Directly invoking window.close() will ask user with a dialogue box.

As far as I know Celery does not give API for examining tasks that are waiting in the queue. This is broker-specific. If you use Redis as a broker for an example, then examining tasks that are waiting in the celery (default) queue is as simple as:

1. connect to the broker database
2. list items in the celery list (LRANGE command for an example)

Keep in mind that these are tasks WAITING to be picked by available workers. Your cluster may have some tasks running - those will not be in this list as they have already been picked.

If you only want to checkout and you delete the folder from the workspace you also need to delete the reference to it in the Java view. Then it should checkout as if it were checking out for the first time.

If multiple clock are generated with different frequencies, then clock generation can be simplified if a procedure is called as concurrent procedure call. The time resolution issue, mentioned by Martin Thompson, may be mitigated a little by using different high and low time in the procedure. The test bench with procedure for clock generation is:

library ieee;
use ieee.std_logic_1164.all;

entity tb is
end entity;

architecture sim of tb is

  -- Procedure for clock generation
  procedure clk_gen(signal clk : out std_logic; constant FREQ : real) is
    constant PERIOD    : time := 1 sec / FREQ;        -- Full period
    constant HIGH_TIME : time := PERIOD / 2;          -- High time
    constant LOW_TIME  : time := PERIOD - HIGH_TIME;  -- Low time; always >= HIGH_TIME
  begin
    -- Check the arguments
    assert (HIGH_TIME /= 0 fs) report "clk_plain: High time is zero; time resolution to large for frequency" severity FAILURE;
    -- Generate a clock cycle
    loop
      clk <= '1';
      wait for HIGH_TIME;
      clk <= '0';
      wait for LOW_TIME;
    end loop;
  end procedure;

  -- Clock frequency and signal
  signal clk_166 : std_logic;
  signal clk_125 : std_logic;

begin

  -- Clock generation with concurrent procedure call
  clk_gen(clk_166, 166.667E6);  -- 166.667 MHz clock
  clk_gen(clk_125, 125.000E6);  -- 125.000 MHz clock

  -- Time resolution show
  assert FALSE report "Time resolution: " & time'image(time'succ(0 fs)) severity NOTE;

end architecture;

The time resolution is printed on the terminal for information, using the concurrent assert last in the test bench.

If the clk_gen procedure is placed in a separate package, then reuse from test bench to test bench becomes straight forward.

Waveform for clocks are shown in figure below.

An more advanced clock generator can also be created in the procedure, which can adjust the period over time to match the requested frequency despite the limitation by time resolution. This is shown here:

-- Advanced procedure for clock generation, with period adjust to match frequency over time, and run control by signal
procedure clk_gen(signal clk : out std_logic; constant FREQ : real; PHASE : time := 0 fs; signal run : std_logic) is
  constant HIGH_TIME   : time := 0.5 sec / FREQ;  -- High time as fixed value
  variable low_time_v  : time;                    -- Low time calculated per cycle; always >= HIGH_TIME
  variable cycles_v    : real := 0.0;             -- Number of cycles
  variable freq_time_v : time := 0 fs;            -- Time used for generation of cycles
begin
  -- Check the arguments
  assert (HIGH_TIME /= 0 fs) report "clk_gen: High time is zero; time resolution to large for frequency" severity FAILURE;
  -- Initial phase shift
  clk <= '0';
  wait for PHASE;
  -- Generate cycles
  loop
    -- Only high pulse if run is '1' or 'H'
    if (run = '1') or (run = 'H') then
      clk <= run;
    end if;
    wait for HIGH_TIME;
    -- Low part of cycle
    clk <= '0';
    low_time_v := 1 sec * ((cycles_v + 1.0) / FREQ) - freq_time_v - HIGH_TIME;  -- + 1.0 for cycle after current
    wait for low_time_v;
    -- Cycle counter and time passed update
    cycles_v := cycles_v + 1.0;
    freq_time_v := freq_time_v + HIGH_TIME + low_time_v;
  end loop;
end procedure;

Again reuse through a package will be nice.

In case anyone has the same problem in the future:

$ adb shell
$ su
# mount -o rw,remount /system

Both adb remount and adb root don't work on a production build without altering ro.secure, but you can still remount /system by opening a shell, asking for root permissions and typing the mount command.

try to add ojdbc6.jar through the server lib "C:\apache-tomcat-7.0.47\lib",

Then restart the server in eclipse.

To add onto bobince's answer... If whatever tool/library you using uses Xpath 2.0, you can also do this:

//*[count(index-of(tokenize(@class, '\s+' ), $classname)) = 1]

count() is apparently needed because index-of() returns a sequence of each index it has a match at in the string.

Had the same problem on Windows 10. The user's %Path% environment already had the required "C:\Users\ user \AppData\Roaming\npm".

path command would not show it, but it did show tons of other paths added earlier by other installations.

Turned out I needed to delete some of them from the system's PATH environment variable.

As far as I understand this happens because there's a length limit on these variables: https://software.intel.com/en-us/articles/limitation-to-the-length-of-the-system-path-variable

Probably happens often on dev machines who install lots of stuff that needs to be in the PATH.

Update 2021, Bootstrap 5

In bootstrap 5 these classes have been renamed to .float-end and .float-start.

Docs: https://getbootstrap.com/docs/5.0/utilities/float/

Example:

<div class="row">
    <div class="col-12">
       <button class="btn btn-primary float-end">Login</div>
    </div>

This could be an answer to your question:

JSONArray msg1 = (JSONArray) json.get("source");
for(int i = 0; i < msg1.length(); i++){
  String name = msg1.getString("name");
  int age     = msg1.getInt("age");
}

gacutil comes with Visual Studio, not with VSTS. It is part of Windows SDK and can be download separately at http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en . This installation will have gacutil.exe included. But first check it here

C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin

you might have it installed.

As @devi mentioned

If you decide to grab gacutil files from existing installation, note that from .NET 4.0 is three files: gacutil.exe gacutil.exe.config and 1033/gacutlrc.dll

I would suggest you take a look at Modernizr. Its a small light weight library that you can asynchronously load your javascript with features that allow you to check if the file is loaded and execute the script in the other you specify.

Here is an example of loading jquery:

Modernizr.load([
  {
    load: '//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.js',
    complete: function () {
      if ( !window.jQuery ) {
            Modernizr.load('js/libs/jquery-1.6.1.min.js');
      }
    }
  },
  {
    // This will wait for the fallback to load and
    // execute if it needs to.
    load: 'needs-jQuery.js'
  }
]);

The title of this thread asks how a subquery can be used in an update. Here's an example of that:

update [dbName].[dbo].[MyTable] 
set MyColumn = 1 
where 
    (
        select count(*) 
        from [dbName].[dbo].[MyTable] mt2 
        where
            mt2.ID > [dbName].[dbo].[MyTable].ID
            and mt2.Category = [dbName].[dbo].[MyTable].Category
    ) > 0

a.sort(function(a,b){return a - b})

These can be confusing.... check this link out.

ALTER TABLE table_name ALTER COLUMN id SET DEFAULT uuid_in((md5((random())::text))::cstring);

After reading @ZuzEL's answer, i used the above code as the default value of the column id and it's working fine.

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.

To solve your requirement, here is the working solution -

First create your ViewModels in following way. PersonModel can have list of RoleModels.

public class PersonModel
{
    public List<RoleModel> Roles { get; set; }
    public string Name { get; set; }
}

public class RoleModel
{
    public string RoleName { get; set;}
    public string Description { get; set;}
}

Then have a index action which will be serving basic index view -

public ActionResult Index()
{
    return View();
}

Index view will be having following JQuery AJAX POST operation -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    $(function () {
        $('#click1').click(function (e) {

            var jsonObject = {
                "Name" : "Rami",
                "Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
            };

            $.ajax({
                url: "@Url.Action("AddUser")",
                type: "POST",
                data: JSON.stringify(jsonObject),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

<input type="button" value="click1" id="click1" />

Index action posts to AddUser action -

[HttpPost]
public ActionResult AddUser(PersonModel model)
{
    if (model != null)
    {
        return Json("Success");
    }
    else
    {
        return Json("An Error Has occoured");
    }
}

So now when the post happens you can get all the posted data in the model parameter of action.

Update:

For asp.net core, to get JSON data as your action parameter you should add the [FromBody] attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController] attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)

First some code, then the explanaition. The official docs describing this are here.

import { trigger, transition, animate, style } from '@angular/animations'

@Component({
  ...
  animations: [
    trigger('slideInOut', [
      transition(':enter', [
        style({transform: 'translateY(-100%)'}),
        animate('200ms ease-in', style({transform: 'translateY(0%)'}))
      ]),
      transition(':leave', [
        animate('200ms ease-in', style({transform: 'translateY(-100%)'}))
      ])
    ])
  ]
})

In your template:

<div *ngIf="visible" [@slideInOut]>This element will slide up and down when the value of 'visible' changes from true to false and vice versa.</div>

I found the angular way a bit tricky to grasp, but once you understand it, it quite easy and powerful.

The animations part in human language:

• We're naming this animation 'slideInOut'.
• When the element is added (:enter), we do the following:
• ->Immediately move the element 100% up (from itself), to appear off screen.

• ->then animate the translateY value until we are at 0%, where the element would naturally be.

• When the element is removed, animate the translateY value (currently 0), to -100% (off screen).

The easing function we're using is ease-in, in 200 milliseconds, you can change that to your liking.

Hope this helps!

Simple solution:

git rm --cached directory
git add directory

Here is the batch file which should work for you:

@echo off
Title HOST: Installing updates on %computername%
echo %computername%
set Server=\\SERVERNAME or PATH\msifolder

:select
cls
echo Select one of the following MSI install folders for installation task.
echo.
dir "%Server%" /AD /ON /B
echo.
set /P "MSI=Please enter the MSI folder to install: "
set "Package=%Server%\%MSI%\%MSI%.msi"

if not exist "%Package%" (
   echo.
   echo The entered folder/MSI file does not exist ^(typing mistake^).
   echo.
   setlocal EnableDelayedExpansion
   set /P "Retry=Try again [Y/N]: "
   if /I "!Retry!"=="Y" endlocal & goto select
   endlocal
   goto :EOF
)

echo.
echo Selected installation: %MSI%
echo.
echo.

:verify
echo Is This Correct?
echo.
echo.
echo    0: ABORT INSTALL
echo    1: YES
echo    2: NO, RE-SELECT
echo.
set /p "choice=Select YES, NO or ABORT? [0,1,2]: "
if [%choice%]==[0] goto :EOF
if [%choice%]==[1] goto yes
goto select

:yes
echo.
echo Running %MSI% installation ...
start "Install MSI" /wait "%SystemRoot%\system32\msiexec.exe" /i /quiet "%Package%"

The characters listed on last page output on entering in a command prompt window either help cmd or cmd /? have special meanings in batch files. Here are used parentheses and square brackets also in strings where those characters should be interpreted literally. Therefore it is necessary to either enclose the string in double quotes or escape those characters with character ^ as it can be seen in code above, otherwise command line interpreter exits batch execution because of a syntax error.

And it is not possible to call a file with extension MSI. A *.msi file is not an executable. On double clicking on a MSI file, Windows looks in registry which application is associated with this file extension for opening action. And the application to use is msiexec with the command line option /i to install the application inside MSI package.

Run msiexec.exe /? to get in a GUI window the available options or look at Msiexec (command-line options).

I have added already /quiet additionally to required option /i for a silent installation.

In batch code above command start is used with option /wait to start Windows application msiexec.exe and hold execution of batch file until installation finished (or aborted).

For a fully transparent background use:

background: transparent;

Otherwise for a semi-transparent color fill use:

background: rgba(255,255,255,0.5); // or hsla(0, 0%, 100%, 0.5)

where the values are:

background: rgba(red,green,blue,opacity); // or hsla(hue, saturation, lightness, opacity)

You can also use rgba values for gradient backgrounds.

To get transparency on an image background simply reduce the opacity of the image in an image editor of you choice beforehand.

WindowsPowershell:

option 1

ping.exe -t COMPUTERNAME|Foreach{"{0} - {1}" -f (Get-Date),$_}

option 2

Test-Connection -Count 9999 -ComputerName COMPUTERNAME | Format-Table @{Name='TimeStamp';Expression={Get-Date}},Address,ProtocolAddress,ResponseTime

I came to this post by way of better understanding the inference of the infamous quote from Mac Lane's Category Theory For the Working Mathematician.

In describing what something is, it's often equally useful to describe what it's not.

The fact that Mac Lane uses the description to describe a Monad, one might imply that it describes something unique to monads. Bear with me. To develop a broader understanding of the statement, I believe it needs to be made clear that he is not describing something that is unique to monads; the statement equally describes Applicative and Arrows among others. For the same reason we can have two monoids on Int (Sum and Product), we can have several monoids on X in the category of endofunctors. But there is even more to the similarities.

Both Monad and Applicative meet the criteria:

• endo => any arrow, or morphism that starts and ends in the same place
• functor => any arrow, or morphism between two Categories

  (e.g., in day to day Tree a -> List b, but in Category Tree -> List)

• monoid => single object; i.e., a single type, but in this context, only in regards to the external layer; so, we can't have Tree -> List, only List -> List.

The statement uses "Category of..." This defines the scope of the statement. As an example, the Functor Category describes the scope of f * -> g *, i.e., Any functor -> Any functor, e.g., Tree * -> List * or Tree * -> Tree *.

What a Categorical statement does not specify describes where anything and everything is permitted.

In this case, inside the functors, * -> * aka a -> b is not specified which means Anything -> Anything including Anything else. As my imagination jumps to Int -> String, it also includes Integer -> Maybe Int, or even Maybe Double -> Either String Int where a :: Maybe Double; b :: Either String Int.

So the statement comes together as follows:

• functor scope :: f a -> g b (i.e., any parameterized type to any parameterized type)
• endo + functor :: f a -> f b (i.e., any one parameterized type to the same parameterized type) ... said differently,
• a monoid in the category of endofunctor

So, where is the power of this construct? To appreciate the full dynamics, I needed to see that the typical drawings of a monoid (single object with what looks like an identity arrow, :: single object -> single object), fails to illustrate that I'm permitted to use an arrow parameterized with any number of monoid values, from the one type object permitted in Monoid. The endo, ~ identity arrow definition of equivalence ignores the functor's type value and both the type and value of the most inner, "payload" layer. Thus, equivalence returns true in any situation where the functorial types match (e.g., Nothing -> Just * -> Nothing is equivalent to Just * -> Just * -> Just * because they are both Maybe -> Maybe -> Maybe).

Sidebar: ~ outside is conceptual, but is the left most symbol in f a. It also describes what "Haskell" reads-in first (big picture); so Type is "outside" in relation to a Type Value. The relationship between layers (a chain of references) in programming is not easy to relate in Category. The Category of Set is used to describe Types (Int, Strings, Maybe Int etc.) which includes the Category of Functor (parameterized Types). The reference chain: Functor Type, Functor values (elements of that Functor's set, e.g., Nothing, Just), and in turn, everything else each functor value points to. In Category the relationship is described differently, e.g., return :: a -> m a is considered a natural transformation from one Functor to another Functor, different from anything mentioned thus far.

Back to the main thread, all in all, for any defined tensor product and a neutral value, the statement ends up describing an amazingly powerful computational construct born from its paradoxical structure:

• on the outside it appears as a single object (e.g., :: List); static
• but inside, permits a lot of dynamics
  • any number of values of the same type (e.g., Empty | ~NonEmpty) as fodder to functions of any arity. The tensor product will reduce any number of inputs to a single value... for the external layer (~fold that says nothing about the payload)
  • infinite range of both the type and values for the inner most layer

In Haskell, clarifying the applicability of the statement is important. The power and versatility of this construct, has absolutely nothing to do with a monad per se. In other words, the construct does not rely on what makes a monad unique.

When trying to figure out whether to build code with a shared context to support computations that depend on each other, versus computations that can be run in parallel, this infamous statement, with as much as it describes, is not a contrast between the choice of Applicative, Arrows and Monads, but rather is a description of how much they are the same. For the decision at hand, the statement is moot.

This is often misunderstood. The statement goes on to describe join :: m (m a) -> m a as the tensor product for the monoidal endofunctor. However, it does not articulate how, in the context of this statement, (<*>) could also have also been chosen. It truly is a an example of six/half dozen. The logic for combining values are exactly alike; same input generates the same output from each (unlike the Sum and Product monoids for Int because they generate different results when combining Ints).

So, to recap: A monoid in the category of endofunctors describes:

   ~t :: m * -> m * -> m *
   and a neutral value for m *

(<*>) and (>>=) both provide simultaneous access to the two m values in order to compute the the single return value. The logic used to compute the return value is exactly the same. If it were not for the different shapes of the functions they parameterize (f :: a -> b versus k :: a -> m b) and the position of the parameter with the same return type of the computation (i.e., a -> b -> b versus b -> a -> b for each respectively), I suspect we could have parameterized the monoidal logic, the tensor product, for reuse in both definitions. As an exercise to make the point, try and implement ~t, and you end up with (<*>) and (>>=) depending on how you decide to define it forall a b.

If my last point is at minimum conceptually true, it then explains the precise, and only computational difference between Applicative and Monad: the functions they parameterize. In other words, the difference is external to the implementation of these type classes.

In conclusion, in my own experience, Mac Lane's infamous quote provided a great "goto" meme, a guidepost for me to reference while navigating my way through Category to better understand the idioms used in Haskell. It succeeds at capturing the scope of a powerful computing capacity made wonderfully accessible in Haskell.

However, there is irony in how I first misunderstood the statement's applicability outside of the monad, and what I hope conveyed here. Everything that it describes turns out to be what is similar between Applicative and Monads (and Arrows among others). What it doesn't say is precisely the small but useful distinction between them.

Your code (which looks ok) doesn't return a pointer to an array. It returns a pointer to the first element of an array.

In fact that's usually what you want to do. Most manipulation of arrays are done via pointers to individual elements, not via pointers to the array as a whole.

You can define a pointer to an array, for example this:

double (*p)[42];

defines p as a pointer to a 42-element array of doubles. A big problem with that is that you have to specify the number of elements in the array as part of the type -- and that number has to be a compile-time constant. Most programs that deal with arrays need to deal with arrays of varying sizes; a given array's size won't vary after it's been created, but its initial size isn't necessarily known at compile time, and different array objects can have different sizes.

A pointer to the first element of an array lets you use either pointer arithmetic or the indexing operator [] to traverse the elements of the array. But the pointer doesn't tell you how many elements the array has; you generally have to keep track of that yourself.

If a function needs to create an array and return a pointer to its first element, you have to manage the storage for that array yourself, in one of several ways. You can have the caller pass in a pointer to (the first element of) an array object, probably along with another argument specifying its size -- which means the caller has to know how big the array needs to be. Or the function can return a pointer to (the first element of) a static array defined inside the function -- which means the size of the array is fixed, and the same array will be clobbered by a second call to the function. Or the function can allocate the array on the heap -- which makes the caller responsible for deallocating it later.

Everything I've written so far is common to C and C++, and in fact it's much more in the style of C than C++. Section 6 of the comp.lang.c FAQ discusses the behavior of arrays and pointers in C.

But if you're writing in C++, you're probably better off using C++ idioms. For example, the C++ standard library provides a number of headers defining container classes such as <vector> and <array>, which will take care of most of this stuff for you. Unless you have a particular reason to use raw arrays and pointers, you're probably better off just using C++ containers instead.

EDIT : I think you edited your question as I was typing this answer. The new code at the end of your question is, as you observer, no good; it returns a pointer to an object that ceases to exist as soon as the function returns. I think I've covered the alternatives.

When I used the reduce function with acc[i] = cur; it returned a kind of object that I needed to access it like a array using this way obj[i].property. But using this way I have the Object that I wanted and I now can access it like obj.property.

 function convertArraytoObject(arr) {
        var obj = arr.reduce(function (acc, cur, i) {
            acc = cur;
            return acc;
        }, {});
        return obj;
    }

You shouldn't use Exceptions to validate your values.

For single character there is a simple solution:

Character.isDigit()

For longer values it's better to use some utils. NumberUtils provided by Apache would work perfectly here:

NumberUtils.isNumber()

Please check https://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/math/NumberUtils.html

Depending on your application and the scope of the cfg file, a properties file might be the easiest. Sure it isn't as elegant as xml but it certainly easier.

Do configure --help and see what other options are available.

It is very common to provide different options to override different locations. By standard, --prefix overrides all of them, so you need to override config location after specifying the prefix. This course of actions usually works for every automake-based project.

The worse case scenario is when you need to modify the configure script, or even worse, generated makefiles and config.h headers. But yeah, for Xfce you can try something like this:

./configure --prefix=/home/me/somefolder/mybuild/output/target --sysconfdir=/etc 

I believe that should do it.

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

You can Use below code to call the web service and get response .Make sure that your Web Service return the response in Data Table Format..This code help you if you using data from SQL Server database .If you you using MYSQL you need to change one thing just replace word NewDataSet from sentence obj2=(SoapObject) obj1.getProperty("NewDataSet"); by DocumentElement

private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://localhost/Web_Service.asmx?"; // you can use   IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = NAMESPACE + METHOD_NAME;

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("parm_name", prm_value); // Parameter for Method
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

try {
    androidHttpTransport.call(SOAP_ACTION, envelope); //call the eb service Method
} catch (Exception e) {
    e.printStackTrace();
} //Next task is to get Response and format that response

SoapObject obj, obj1, obj2, obj3;
obj = (SoapObject) envelope.getResponse();
obj1 = (SoapObject) obj.getProperty("diffgram");
obj2 = (SoapObject) obj1.getProperty("NewDataSet");

for (int i = 0; i < obj2.getPropertyCount(); i++) //the method getPropertyCount() return the number of rows
{
    obj3 = (SoapObject) obj2.getProperty(i);
    obj3.getProperty(0).toString(); //value of column 1
    obj3.getProperty(1).toString(); //value of column 2
    //like that you will get value from each column
}

If you have any problem regarding this you can write me..

Supopose you want to copy oldList into a new ArrayList object called newList

ArrayList<Object> newList = new ArrayList<>() ;

for (int i = 0 ; i<oldList.size();i++){
    newList.add(oldList.get(i)) ;
}

These two lists are indepedant, changes to one are not reflected to the other one.

I had a list of dataframes with no common id column.
I had missing data on many dfs. There were Null values. The dataframes were produced using table function. The Reduce, Merging, rbind, rbind.fill, and their like could not help me to my aim. My aim was to produce an understandable merged dataframe, irrelevant of the missing data and common id column.

Therefore, I made the following function. Maybe this function can help someone.

The include tag

The <include> tag lets you to divide your layout into multiple files: it helps dealing with complex or overlong user interface.

Let's suppose you split your complex layout using two include files as follows:

top_level_activity.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <include layout="@layout/include1.xml" />

    <!-- Second include file -->
    <include layout="@layout/include2.xml" />

</LinearLayout>

Then you need to write include1.xml and include2.xml.

Keep in mind that the xml from the include files is simply dumped in your top_level_activity layout at rendering time (pretty much like the #INCLUDE macro for C).

The include files are plain jane layout xml.

include1.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textView1"
    android:text="First include"
    android:textAppearance="?android:attr/textAppearanceMedium"/>

... and include2.xml:

<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/button1"
    android:text="Button" />

See? Nothing fancy. Note that you still have to declare the android namespace with xmlns:android="http://schemas.android.com/apk/res/android.

So the rendered version of top_level_activity.xml is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <TextView
        android:id="@+id/textView1"
        android:text="First include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <!-- Second include file -->
    <Button
        android:id="@+id/button1"
        android:text="Button" />


</LinearLayout>

In your java code, all this is transparent: findViewById(R.id.textView1) in your activity class returns the correct widget ( even if that widget was declared in a xml file different from the activity layout).

And the cherry on top: the visual editor handles the thing swimmingly. The top level layout is rendered with the xml included.

The plot thickens

As an include file is a classic layout xml file, it means that it must have one top element. So in case your file needs to include more than one widget, you would have to use a layout.

Let's say that include1.xml has now two TextView: a layout has to be declared. Let's choose a LinearLayout.

include1.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout2" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

</LinearLayout>

The top_level_activity.xml will be rendered as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file -->
    <LinearLayout 
        android:id="@+id/layout2" 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

       <TextView
            android:id="@+id/textView1"
            android:text="Second include"
            android:textAppearance="?android:attr/textAppearanceMedium"/>

       <TextView
            android:id="@+id/textView2"
            android:text="More text"
            android:textAppearance="?android:attr/textAppearanceMedium"/>

   </LinearLayout>

     <!-- Second include file -->
   <Button
        android:id="@+id/button1"
        android:text="Button" />

</LinearLayout>

But wait the two levels of LinearLayout are redundant!

Indeed, the two nested LinearLayout serve no purpose as the two TextView could be included under layout1for exactly the same rendering.

So what can we do?

Enter the merge tag

The <merge> tag is just a dummy tag that provides a top level element to deal with this kind of redundancy issues.

Now include1.xml becomes:

<merge xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

</merge>

and now top_level_activity.xml is rendered as:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout1" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <!-- First include file --> 
    <TextView
        android:id="@+id/textView1"
        android:text="Second include"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <TextView
        android:id="@+id/textView2"
        android:text="More text"
        android:textAppearance="?android:attr/textAppearanceMedium"/>

    <!-- Second include file -->
    <Button
        android:id="@+id/button1"
        android:text="Button" />

</LinearLayout>

You saved one hierarchy level, avoid one useless view: Romain Guy sleeps better already.

Aren't you happier now?

Yup, there's the convert_tz function.

Try + (instancetype)appearance of UITableView:

Objective-C:

[[UITableView appearance] setSeparatorColor:[UIColor blackColor]]; // set your desired colour in place of "[UIColor blackColor]"

Swift 3.0:

UITableView.appearance().separatorColor = UIColor.black // set your desired colour in place of "UIColor.black"

Note: Change will reflect to all tables used in application.

For passing a single integer I agree with Reed Copsey's answer. If in the future you are going to pass more complicated constucts I personally like to pass all my variables as an Anonymous Type. It will look something like this:

foreach(int id in myIdsToCheck)
{
    Task.Factory.StartNew( (Object obj) => 
        {
           var data = (dynamic)obj;
           CheckFiles(data.id, theBlockingCollection,
               cancelCheckFile.Token, 
               TaskCreationOptions.LongRunning, 
               TaskScheduler.Default);
        }, new { id = id }); // Parameter value
}

You can learn more about it in my blog

As per the Newtonsoft Documentation you can also deserialize to an anonymous object like this:

var definition = new { Name = "" };

string json1 = @"{'Name':'James'}";
var customer1 = JsonConvert.DeserializeAnonymousType(json1, definition);

Console.WriteLine(customer1.Name);
// James

Before you can commit and push, you need to init a working repository tree for a submodule. I am using tortoise and do following things:

First check if there exist .git file (not a directory)

• if there is such file it contains path to supermodule git directory
• delete this file
• do git init
• do git add remote path the one used for submodule
• follow instructions below

If there was .git file, there surly was .git directory which tracks local tree. You still need to a branch (you can create one) or switch to master (which sometimes does not work). Best to do is - git fetch - git pull. Do not omit fetch.

Now your commits and pulls will be synchronized with your origin/master

There is an alternative command where you can get the raw value of a cell where formula is put on. It's returns type is String. Use:

cell.getRawValue();

What am I doing incorrectly?

You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.

How can I receive a json object in the controller?

View:

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>

var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });

<form id="form1" method="post">
<input name="OrderDate" type="text" /><br />
<input name="Item[0][Id]" type="text" /><br />
<input name="Item[1][Id]" type="text" /><br />
<button id="btn" onclick="btnClick()">Button</button>
</form>

Controller:

public void PostRawJson(string json)
{
    var order = System.Web.Helpers.Json.Decode(json);
    var orderDate = order.OrderDate;
    var secondOrderId = order.Item[1].Id;
}

Tomcat will only extract the war which is copied to webapps directory. Change Dockerfile as below:

FROM tomcat:8.0.20-jre8
COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war

You might need to access the url as below unless you have specified the webroot

http://192.168.59.103:8888/myapp/getData

very simply we can say:

• black box: user interface test like functional test

Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.

After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.

If you don't need to store it, you can reduce the time spent like this:

void showReverse(char s[], int length)
{
    printf("Reversed String without storing is ");
    //could use another variable to test for length, keeping length whole.
    //assumes contiguous memory
    for (; length > 0; length--)
    {
        printf("%c", *(s+ length-1) );
    }
    printf("\n");
}

Since your question is more generic so try to implement it with XML Parsers available in Java .If you need it in specific to parsers, update your code here what you have tried yet

<?xml version="1.0" encoding="UTF-8"?>
<ep>
    <source type="xml">TEST</source>
    <source type="text"></source>
</ep>

DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse("uri to xmlfile");
XPathFactory xPathfactory = XPathFactory.newInstance();
XPath xpath = xPathfactory.newXPath();
XPathExpression expr = xpath.compile("//ep/source[@type]");
NodeList nl = (NodeList) expr.evaluate(doc, XPathConstants.NODESET);

for (int i = 0; i < nl.getLength(); i++)
{
    Node currentItem = nl.item(i);
    String key = currentItem.getAttributes().getNamedItem("type").getNodeValue();
    System.out.println(key);
}

As of Rails 2.3.9, there is a setting in config/application.rb in which you can specify directories that contain files you want autoloaded.

From application.rb:

# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)

Here's a function I've been testing with jquery 1.3.2 and 09-18-2009's nightly build. Let me know your results with it. Everything executes fine on this end in Safari, FF, Opera on OSX. It is exclusively for fixing a problematic IE8 bug, and may have unintended results:

function ie8SafePreventEvent(e) {
    if (e.preventDefault) {
        e.preventDefault()
    } else {
        e.stop()
    };

    e.returnValue = false;
    e.stopPropagation();
}

Usage:

$('a').click(function (e) {
    // Execute code here
    ie8SafePreventEvent(e);
    return false;
})

for center and auto zoom on display markers

// map: an instance of google.maps.Map object

// latlng_points_array: an array of google.maps.LatLng objects

var latlngbounds = new google.maps.LatLngBounds( );

    for ( var i = 0; i < latlng_points_array.length; i++ ) {
        latlngbounds.extend( latlng_points_array[i] );
    }

map.fitBounds( latlngbounds );

As clarified in your comment, Spacemoses, you stated an example: WHERE (Note is null) ^ (ID is null). I do not see why you chose to accept any answer given here as answering that. If i needed an xor for that, i think i'd have to use the AND/OR equivalent logic:

WHERE (Note is null and ID is not null) OR (Note is not null and ID is null)

That is equivalent to:

WHERE (Note is null) XOR (ID is null)

when 'XOR' is not available.

select region,sum(number) total
from
(
    select region,number
    from cash_table
    union all
    select region,number
    from cheque_table
) t
group by region

You can try this way

 String input = "";
 try {
   int x = Integer.parseInt(input); 
   // You can use this method to convert String to int, But if input 
   //is not an int  value then this will throws NumberFormatException. 
   System.out.println("Valid input");
 }catch(NumberFormatException e) {
   System.out.println("input is not an int value"); 
   // Here catch NumberFormatException
   // So input is not a int.
 } 

Similar question has been asked in stackoverflow before.

See here: PHP $_SERVER['HTTP_HOST'] vs. $_SERVER['SERVER_NAME'], am I understanding the man pages correctly?

Also see this article: http://shiflett.org/blog/2006/mar/server-name-versus-http-host

Recommended using HTTP_HOST, and falling back on SERVER_NAME only if HTTP_HOST was not set. He said that SERVER_NAME could be unreliable on the server for a variety of reasons, including:

• no DNS support
• misconfigured
• behind load balancing software

We're doing load testing now. We think we can support 240 concurrent requests (a sustained rate of 120 hits per second 24x7) without any significant degradation in the server performance. That would be 432,000 hits per hour. Response times aren't small (our transactions are large) but there's no degradation from our baseline performance as the load increases.

We're using Apache front-ending Django and MySQL. The OS is Red Hat Enterprise Linux (RHEL). 64-bit. We use mod_wsgi in daemon mode for Django. We've done no cache or database optimization other than to accept the defaults.

We're all in one VM on a 64-bit Dell with (I think) 32Gb RAM.

Since performance is almost the same for 20 or 200 concurrent users, we don't need to spend huge amounts of time "tweaking". Instead we simply need to keep our base performance up through ordinary SSL performance improvements, ordinary database design and implementation (indexing, etc.), ordinary firewall performance improvements, etc.

What we do measure is our load test laptops struggling under the insane workload of 15 processes running 16 concurrent threads of requests.

If PHP is installed then indeed, just use the php info command:

<?php phpinfo(); ?>

To make @Raghavendra's answer more specific:

Once you've downloaded 2 zip files,

copy ALL the contents of "win64_11gR2_database_2of2.zip -> Database -> Stage -> Components" folder to "win64_11gR2_database_1of2.zip -> Database -> Stage -> Components" folder.

You'll still get the same warning, however, the installation will run completely without generating any errors.

The nohup command only writes to nohup.out if the output would otherwise go to the terminal. If you have redirected the output of the command somewhere else - including /dev/null - that's where it goes instead.

 nohup command >/dev/null 2>&1   # doesn't create nohup.out

If you're using nohup, that probably means you want to run the command in the background by putting another & on the end of the whole thing:

 nohup command >/dev/null 2>&1 & # runs in background, still doesn't create nohup.out

On Linux, running a job with nohup automatically closes its input as well. On other systems, notably BSD and macOS, that is not the case, so when running in the background, you might want to close input manually. While closing input has no effect on the creation or not of nohup.out, it avoids another problem: if a background process tries to read anything from standard input, it will pause, waiting for you to bring it back to the foreground and type something. So the extra-safe version looks like this:

nohup command </dev/null >/dev/null 2>&1 & # completely detached from terminal 

Note, however, that this does not prevent the command from accessing the terminal directly, nor does it remove it from your shell's process group. If you want to do the latter, and you are running bash, ksh, or zsh, you can do so by running disown with no argument as the next command. That will mean the background process is no longer associated with a shell "job" and will not have any signals forwarded to it from the shell. (Note the distinction: a disowned process gets no signals forwarded to it automatically by its parent shell - but without nohup, it will still receive a HUP signal sent via other means, such as a manual kill command. A nohup'ed process ignores any and all HUP signals, no matter how they are sent.)

Explanation:

In Unixy systems, every source of input or target of output has a number associated with it called a "file descriptor", or "fd" for short. Every running program ("process") has its own set of these, and when a new process starts up it has three of them already open: "standard input", which is fd 0, is open for the process to read from, while "standard output" (fd 1) and "standard error" (fd 2) are open for it to write to. If you just run a command in a terminal window, then by default, anything you type goes to its standard input, while both its standard output and standard error get sent to that window.

But you can ask the shell to change where any or all of those file descriptors point before launching the command; that's what the redirection (<, <<, >, >>) and pipe (|) operators do.

The pipe is the simplest of these... command1 | command2 arranges for the standard output of command1 to feed directly into the standard input of command2. This is a very handy arrangement that has led to a particular design pattern in UNIX tools (and explains the existence of standard error, which allows a program to send messages to the user even though its output is going into the next program in the pipeline). But you can only pipe standard output to standard input; you can't send any other file descriptors to a pipe without some juggling.

The redirection operators are friendlier in that they let you specify which file descriptor to redirect. So 0<infile reads standard input from the file named infile, while 2>>logfile appends standard error to the end of the file named logfile. If you don't specify a number, then input redirection defaults to fd 0 (< is the same as 0<), while output redirection defaults to fd 1 (> is the same as 1>).

Also, you can combine file descriptors together: 2>&1 means "send standard error wherever standard output is going". That means that you get a single stream of output that includes both standard out and standard error intermixed with no way to separate them anymore, but it also means that you can include standard error in a pipe.

So the sequence >/dev/null 2>&1 means "send standard output to /dev/null" (which is a special device that just throws away whatever you write to it) "and then send standard error to wherever standard output is going" (which we just made sure was /dev/null). Basically, "throw away whatever this command writes to either file descriptor".

When nohup detects that neither its standard error nor output is attached to a terminal, it doesn't bother to create nohup.out, but assumes that the output is already redirected where the user wants it to go.

The /dev/null device works for input, too; if you run a command with </dev/null, then any attempt by that command to read from standard input will instantly encounter end-of-file. Note that the merge syntax won't have the same effect here; it only works to point a file descriptor to another one that's open in the same direction (input or output). The shell will let you do >/dev/null <&1, but that winds up creating a process with an input file descriptor open on an output stream, so instead of just hitting end-of-file, any read attempt will trigger a fatal "invalid file descriptor" error.

There are two things you can do:

1. Add the @Deprecated annotation to the method, and
2. Add a @deprecated tag to the javadoc of the method

You should do both!

Quoting the java documentation on this subject:

Starting with J2SE 5.0, you deprecate a class, method, or field by using the @Deprecated annotation. Additionally, you can use the @deprecated Javadoc tag tell developers what to use instead.

Using the annotation causes the Java compiler to generate warnings when the deprecated class, method, or field is used. The compiler suppresses deprecation warnings if a deprecated compilation unit uses a deprecated class, method, or field. This enables you to build legacy APIs without generating warnings.

You are strongly recommended to use the Javadoc @deprecated tag with appropriate comments explaining how to use the new API. This ensures developers will have a workable migration path from the old API to the new API

I always prefer to read input using nextLine() and then parse the string.

Using next() will only return what comes before the delimiter (defaults to whitespace). nextLine() automatically moves the scanner down after returning the current line.

A useful tool for parsing data from nextLine() would be str.split("\\s+").

String data = scanner.nextLine();
String[] pieces = data.split("\\s+");
// Parse the pieces

For more information regarding the Scanner class or String class refer to the following links.

Scanner: http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html

String: http://docs.oracle.com/javase/7/docs/api/java/lang/String.html

I also needed a button to navigate left on a PageViewController, one that should do exactly what you would expect from the swipe motion.

Since I had a few rules already in place inside "pageViewController:viewControllerBeforeViewController" for dealing with the natural swipe navigation, I wanted the button to re-use all that code, and simply could not afford to use specific indexes to reach pages as the previous answers did. So, I had to take an alternate solution.

Please note that the following code is for a Page View Controller that is a property inside my custom ViewController, and has its spine set to mid.

Here is the code I wrote for my Navigate Left button:

- (IBAction)btnNavigateLeft_Click:(id)sender {

    // Calling the PageViewController to obtain the current left page
    UIViewController *currentLeftPage = [_pageController.viewControllers objectAtIndex:0];

    // Creating future pages to be displayed
    NSArray *newDisplayedPages = nil;
    UIViewController *newRightPage = nil;
    UIViewController *newLeftPage = nil;

    // Calling the delegate to obtain previous pages
    // My "pageViewController:viewControllerBeforeViewController" method returns nil if there is no such page (first page of the book).
    newRightPage = [self pageViewController:_pageController viewControllerBeforeViewController:currentLeftPage];
    if (newRightPage) {
        newLeftPage = [self pageViewController:_pageController viewControllerBeforeViewController:newRightPage];
    }

    if (newLeftPage) {
        newDisplayedPages = [[NSArray alloc] initWithObjects:newLeftPage, newRightPage, nil];
    }

    // If there are two new pages to display, show them with animation.
    if (newDisplayedPages) {
        [_pageController setViewControllers:newDisplayedPages direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:nil];

You can do something very similar to make a right navigation button from here.

• 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

  document.getElementById('myinput').onkeydown = function(e) {
      if(!((e.keyCode > 95 && e.keyCode < 106)
      || (e.keyCode > 47 && e.keyCode < 58) 
      || e.keyCode == 8
      || e.keyCode == 9)) {
        return false;
      }
  }

I think that there is a more simple approach to all given here, and is the method Number.toFixed() already implemented in JavaScript.

simply write:

var myNumber = 2;

myNumber.toFixed(2); //returns "2.00"
myNumber.toFixed(1); //returns "2.0"

etc...

Now you can use ViewPager2 for dynamically adding, removing fragment from the viewpager.

Quoting form API reference

ViewPager2 replaces ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.

Take look at MutableCollectionFragmentActivity.kt in googlesample/android-viewpager2 for an example of adding, removing fragments dynamically from the viewpager.

It is specific from your driver. You need to supply a parameter in your Java program to tell it the time zone you want to use.

java -Duser.timezone="America/New_York" GetCurrentDateTimeZone

Further this:

to_char(new_time(sched_start_time, 'CURRENT_TIMEZONE', 'NEW_TIMEZONE'), 'MM/DD/YY HH:MI AM')

May also be of value in handling the conversion properly. Taken from here

Note that iPhone 6 will use the 320pt (640px) resolution if you have enabled the 'Display Zoom' in iPhone > Settings > Display & Brightness > View.

Here is a demo. Use position:fixed; top:0; left:0; so the header always stay on top.

?#header {
    background:red;
    height:50px;
    width:100%;
    position:fixed;
    top:0;
    left:0;

LinkedIn has updated their api and the sharing url's no longer works. Now you can only use the url query parameter. Any other parameter is going to be removed from the url by LinkedIn.

Now you're forced to use oAuth and interact with the linkedin API to share content on behalf of a user.

print locals()

To make it look a little prettier when printing:

import sys, pprint
sys.displayhook = pprint.pprint
locals()

That should give you a more vertical printout.

A segementation fault is an internal error in php (or, less likely, apache). Oftentimes, the segmentation fault is caused by one of the newer and lesser-tested php modules such as imagemagick or subversion.

Try disabling all non-essential modules (in php.ini), and then re-enabling them one-by-one until the error occurs. You may also want to update php and apache.

If that doesn't help, you should report a php bug.

• Make your first pivot table.

• Select the first top left cell.

• Create a range name using offset:

  OFFSET(Sheet1!$A$3,0,0,COUNTA(Sheet1!$A:$A)-1,COUNTA(Sheet1!$3:$3))

• Make your second pivot with your range name as source of data using F3.

If you change number of rows or columns from your first pivot, your second pivot will be update after refreshing pivot

Mine got resolved by adding info in persistence.xml e.g. <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> and then making sure you have the library on classpath e.g. in Maven add dependency like

<dependency>
  <groupId>org.eclipse.persistence</groupId>
  <artifactId>eclipselink</artifactId>
  <version>2.5.0</version>
</dependency>

I often use the simplest way:

var variable;
if (variable === undefined){
    console.log('Variable is undefined');
} else {
    console.log('Variable is defined');
}

EDIT:

Without initializing the variable, exception will be thrown "Uncaught ReferenceError: variable is not defined..."

i was looking information about how to do a POST request. I need to specify that mi request is a POST request because, i'm working with RESTful web services that only uses POST methods, and if the request isn't post, when i try to do the request i receive an HTTP error 405. I assure that my code isn't wrong doing the next: I create a method in my web service that is called through GET request and i point my application to consume that web service method and it works. My code is the next:

    URL server = null;
    URLConnection conexion = null;
    BufferedReader reader = null;
    server = new URL("http://localhost:8089/myApp/resources/webService");
    conexion = server.openConnection();
    reader = new BufferedReader(new InputStreamReader(server.openStream()));
    System.out.println(reader.readLine());

This instruction works fine:

Thread.currentThread().getStackTrace()[1].getClassName();

Here's a simple example function using python. You can stick in ~/.bashrc
You gotta have a space after the first left curly bracket
The python command needs to be in double quotes to get the variable substitution

AFAIK you cannot use VBA Excel to create custom tab in the Excel ribbon. You can however hide/make visible a ribbon component using VBA. Additionally, the link that you mentioned above is for MS Project and not MS Excel.

I create tabs for my Excel Applications/Add-Ins using this free utility called Custom UI Editor.

Edit: To accommodate new request by OP

Tutorial

Here is a short tutorial as promised:

1. After you have installed the Custom UI Editor (CUIE), open it and then click on File | Open and select the relevant Excel File. Please ensure that the Excel File is closed before you open it via CUIE. I am using a brand new worksheet as an example.

   

2. Right click as shown in the image below and click on "Office 2007 Custom UI Part". It will insert the "customUI.xml"

   

3. Next Click on menu Insert | Sample XML | Custom Tab. You will notice that the basic code is automatically generated. Now you are all set to edit it as per your requirements.

   

4. Let's inspect the code

   

   label="Custom Tab": Replace "Custom Tab" with the name which you want to give your tab. For the time being let's call it "Jerome".

   The below part adds a custom button.

   <button id="customButton" label="Custom Button" imageMso="HappyFace" size="large" onAction="Callback" />
   

   imageMso: This is the image that will display on the button. "HappyFace" is what you will see at the moment. You can download more image ID's here.

   onAction="Callback": "Callback" is the name of the procedure which runs when you click on the button.

Demo

With that, let's create 2 buttons and call them "JG Button 1" and "JG Button 2". Let's keep happy face as the image of the first one and let's keep the "Sun" for the second. The amended code now looks like this:

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon startFromScratch="false">
<tabs>
<tab id="MyCustomTab" label="Jerome" insertAfterMso="TabView">
<group id="customGroup1" label="First Tab">
<button id="customButton1" label="JG Button 1" imageMso="HappyFace" size="large" onAction="Callback1" />
<button id="customButton2" label="JG Button 2" imageMso="PictureBrightnessGallery" size="large" onAction="Callback2" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>

Delete all the code which was generated in CUIE and then paste the above code in lieu of that. Save and close CUIE. Now when you open the Excel File it will look like this:

Now the code part. Open VBA Editor, insert a module, and paste this code:

Public Sub Callback1(control As IRibbonControl)

    MsgBox "You pressed Happy Face"

End Sub

Public Sub Callback2(control As IRibbonControl)

    MsgBox "You pressed the Sun"

End Sub

Save the Excel file as a macro enabled file. Now when you click on the Smiley or the Sun you will see the relevant message box:

Hope this helps!

use command npm init -f to generate package.json file and after that use --save after each command so that each module will automatically get updated inside your package.json for ex: npm install express --save

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

In this mode you can find all element which has class active and remove it

try this

$(document).ready(function() {
        $(this.attr('id')).click(function () {
           $(document).find('.active').removeClass('active');
           var DivId = $(this).attr('id');
           alert(DivId);
           $(this).addClass('active');
        });
  });

For anyone using Koa and koa-passport:

Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:

this.session.passport.user

When you set in done(null, user) in deserializeUser where 'user' is some user object from your database:

this.req.user OR this.passport.user

for some reason this.user Koa context never gets set when you call done(null, user) in your deserializeUser method.

So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:

app.use(function * setUserInContext (next) {
  this.user = this.req.user
  yield next
})

If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher

There is difference between both $(this).closest('div') and $(this).parents('div').eq(0)

Basically closest start matching element from the current element whereas parents start matching elements from parent (one level above the current element)

The only way that I have found to do this is VIM or Notepad++.

Even though Logger.log() is technically the correct way to output something to the console, it has a few annoyances:

1. The output can be an unstructured mess and hard to quickly digest.
2. You have to first run the script, then click View / Logs, which is two extra clicks (one if you remember the Ctrl+Enter keyboard shortcut).
3. You have to insert Logger.log(playerArray), and then after debugging you'd probably want to remove Logger.log(playerArray), hence an additional 1-2 more steps.
4. You have to click on OK to close the overlay (yet another extra click).

Instead, whenever I want to debug something I add breakpoints (click on line number) and press the Debug button (bug icon). Breakpoints work well when you are assigning something to a variable, but not so well when you are initiating a variable and want to peek inside of it at a later point, which is similar to what the op is trying to do. In this case, I would force a break condition by entering "x" (x marks the spot!) to throw a run-time error:

Compare with viewing Logs:

The Debug console contains more information and is a lot easier to read than the Logs overlay. One minor benefit with this method is that you never have to worry about polluting your code with a bunch of logging commands if keeping clean code is your thing. Even if you enter "x", you are forced to remember to remove it as part of the debugging process or else your code won't run (built-in cleanup measure, yay).

do this:

$("tr.item").each(function(i, tr) {
    var value = $("span.value", tr).text();
    var quantity = $("input.quantity", tr).val();
});

DBCC CHECKIDENT('databasename.dbo.tablename', RESEED, number)

if number=0 then in the next insert the auto increment field will contain value 1

if number=101 then in the next insert the auto increment field will contain value 102

Some additional info... May be useful to you

Before giving auto increment number in above query, you have to make sure your existing table's auto increment column contain values less that number.

To get the maximum value of a column(column_name) from a table(table1), you can use following query

 SELECT MAX(column_name) FROM table1

As you are using SQL Server 2008, go with Martin's answer.

If you find yourself needing to do it in SQL Server 2005 where you don't have access to the Date column type, I'd use:

SELECT DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0)

SQLFiddle

SQL injection can be a tricky problem but there are ways around it. Your risk is reduced your risk simply by using an ORM like Linq2Entities, Linq2SQL, NHibrenate. However you can have SQL injection problems even with them.

The main thing with SQL injection is user controlled input (as is with XSS). In the most simple example if you have a login form (I hope you never have one that just does this) that takes a username and password.

SELECT * FROM Users WHERE Username = '" + username + "' AND password = '" + password + "'"

If a user were to input the following for the username Admin' -- the SQL Statement would look like this when executing against the database.

SELECT * FROM Users WHERE Username = 'Admin' --' AND password = ''

In this simple case using a paramaterized query (which is what an ORM does) would remove your risk. You also have a the issue of a lesser known SQL injection attack vector and that's with stored procedures. In this case even if you use a paramaterized query or an ORM you would still have a SQL injection problem. Stored procedures can contain execute commands, and those commands themselves may be suceptable to SQL injection attacks.

CREATE PROCEDURE SP_GetLogin @username varchar(100), @password varchar(100) AS
DECLARE @sql nvarchar(4000)
SELECT @sql = ' SELECT * FROM users' +
              ' FROM Product Where username = ''' + @username + ''' AND password = '''+@password+''''

EXECUTE sp_executesql @sql

So this example would have the same SQL injection problem as the previous one even if you use paramaterized queries or an ORM. And although the example seems silly you'd be surprised as to how often something like this is written.

My recommendations would be to use an ORM to immediately reduce your chances of having a SQL injection problem, and then learn to spot code and stored procedures which can have the problem and work to fix them. I don't recommend using ADO.NET (SqlClient, SqlCommand etc...) directly unless you have to, not because it's somehow not safe to use it with parameters but because it's that much easier to get lazy and just start writing a SQL query using strings and just ignoring the parameters. ORMS do a great job of forcing you to use parameters because it's just what they do.

Next Visit the OWASP site on SQL injection https://www.owasp.org/index.php/SQL_Injection and use the SQL injection cheat sheet to make sure you can spot and take out any issues that will arise in your code. https://www.owasp.org/index.php/SQL_Injection_Prevention_Cheat_Sheet finally I would say put in place a good code review between you and other developers at your company where you can review each others code for things like SQL injection and XSS. A lot of times programmers miss this stuff because they're trying to rush out some feature and don't spend too much time on reviewing their code.

This one worked for me:

def list = [1,2,3,4]
for(item in list){
    println item
}

Use:

find . 2>/dev/null > files_and_folders

This hides not just the Permission denied errors, of course, but all error messages.

If you really want to keep other possible errors, such as too many hops on a symlink, but not the permission denied ones, then you'd probably have to take a flying guess that you don't have many files called 'permission denied' and try:

find . 2>&1 | grep -v 'Permission denied' > files_and_folders

If you strictly want to filter just standard error, you can use the more elaborate construction:

find . 2>&1 > files_and_folders | grep -v 'Permission denied' >&2

The I/O redirection on the find command is: 2>&1 > files_and_folders |. The pipe redirects standard output to the grep command and is applied first. The 2>&1 sends standard error to the same place as standard output (the pipe). The > files_and_folders sends standard output (but not standard error) to a file. The net result is that messages written to standard error are sent down the pipe and the regular output of find is written to the file. The grep filters the standard output (you can decide how selective you want it to be, and may have to change the spelling depending on locale and O/S) and the final >&2 means that the surviving error messages (written to standard output) go to standard error once more. The final redirection could be regarded as optional at the terminal, but would be a very good idea to use it in a script so that error messages appear on standard error.

There are endless variations on this theme, depending on what you want to do. This will work on any variant of Unix with any Bourne shell derivative (Bash, Korn, …) and any POSIX-compliant version of find.

If you wish to adapt to the specific version of find you have on your system, there may be alternative options available. GNU find in particular has a myriad options not available in other versions — see the currently accepted answer for one such set of options.

Bear in mind that you may need to include a version number too as you could be using either:

First you have to get the localVisible rectangle of the view

For eg:

Rect rectf = new Rect();

//For coordinates location relative to the parent
anyView.getLocalVisibleRect(rectf);

//For coordinates location relative to the screen/display
anyView.getGlobalVisibleRect(rectf);

Log.d("WIDTH        :", String.valueOf(rectf.width()));
Log.d("HEIGHT       :", String.valueOf(rectf.height()));
Log.d("left         :", String.valueOf(rectf.left));
Log.d("right        :", String.valueOf(rectf.right));
Log.d("top          :", String.valueOf(rectf.top));
Log.d("bottom       :", String.valueOf(rectf.bottom));

Here is a simple context manager that prints to the console and writes the same output to an file. It also writes any exceptions to the file.

import traceback
import sys

# Context manager that copies stdout and any exceptions to a log file
class Tee(object):
    def __init__(self, filename):
        self.file = open(filename, 'w')
        self.stdout = sys.stdout

    def __enter__(self):
        sys.stdout = self

    def __exit__(self, exc_type, exc_value, tb):
        sys.stdout = self.stdout
        if exc_type is not None:
            self.file.write(traceback.format_exc())
        self.file.close()

    def write(self, data):
        self.file.write(data)
        self.stdout.write(data)

    def flush(self):
        self.file.flush()
        self.stdout.flush()

To use the context manager:

print("Print")
with Tee('test.txt'):
    print("Print+Write")
    raise Exception("Test")
print("Print")

I've renamed the project' subfolder from: "android/app/src/main/java/MY/APP/OLD_ID/" to: "android/app/src/main/java/MY/APP/NEW_ID/"

In android/app/src/main/java/MY/APP/NEW_ID/MainApplication.java:

package MY.APP.NEW_ID;

In android/app/src/main/AndroidManifest.xml:

package="MY.APP.NEW_ID"

And in android/app/build.gradle:

applicationId "MY.APP.NEW_ID"

In android/app/BUCK:

android_build_config(
  package="MY.APP.NEW_ID"
)
android_resource(
  package="MY.APP.NEW_ID"
)

Gradle' cleaning in the end (in /android folder):

Use a wrapper

Any kind of wrapper is good.

With Java 8+, use either an AtomicInteger:

AtomicInteger ordinal = new AtomicInteger(0);
list.forEach(s -> {
  s.setOrdinal(ordinal.getAndIncrement());
});

... or an array:

int[] ordinal = { 0 };
list.forEach(s -> {
  s.setOrdinal(ordinal[0]++);
});

With Java 10+:

var wrapper = new Object(){ int ordinal = 0; };
list.forEach(s -> {
  s.setOrdinal(wrapper.ordinal++);
});

Note: be very careful if you use a parallel stream. You might not end up with the expected result. Other solutions like Stuart's might be more adapted for those cases.

For types other than int

Of course, this is still valid for types other than int. You only need to change the wrapping type to an AtomicReference or an array of that type. For instance, if you use a String, just do the following:

AtomicReference<String> value = new AtomicReference<>();
list.forEach(s -> {
  value.set("blah");
});

Use an array:

String[] value = { null };
list.forEach(s-> {
  value[0] = "blah";
});

Or with Java 10+:

var wrapper = new Object(){ String value; };
list.forEach(s->{

That is okay for removing of data connections by using VBA as follows:

Sub deleteConn()
    Dim xlBook As Workbook
    Dim Cn As WorkbookConnection
    Dim xlSheet As Worksheet
    Dim Qt As QueryTable
    Set xlBook = ActiveWorkbook
    For Each Cn In xlBook.Connections
        Debug.Print VarType(Cn)
        Cn.Delete
    Next Cn
    For Each xlSheet In xlBook.Worksheets
        For Each Qt In xlSheet.QueryTables
            Debug.Print Qt.Name
            Qt.Delete
        Next Qt
    Next xlSheet
End Sub
