I was also having the same problem So I just removed the JDK path from the end and put it in start even before all System or Windows 32 paths.

Before it was like this:

C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Program Files\doxygen\bin;%JAVA_HOME%\bin;%ANT_HOME%\bin

So I made it like this:

%JAVA_HOME%\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Users\Rajkaran\AppData\Local\Smartbar\Application\;C:\Program Files\doxygen\bin;%ANT_HOME%\bin

Sometimes while installing JDK, you may get a dll is missing error. Because of this, it won't copy the tools.jar file to the java folder. So please reinstall the JDK in a different location and if it is successful then you will see the tools.jar file.

You can use list comprehension on a dataframe to count frequencies of the columns as such

[my_series[c].value_counts() for c in list(my_series.select_dtypes(include=['O']).columns)]

Breakdown:

my_series.select_dtypes(include=['O']) 

Selects just the categorical data

list(my_series.select_dtypes(include=['O']).columns) 

Turns the columns from above into a list

[my_series[c].value_counts() for c in list(my_series.select_dtypes(include=['O']).columns)] 

Iterates through the list above and applies value_counts() to each of the columns

You should not be doing this. Instead, do:

test1.py:

 def print_test():
      print "I am a test"
      print "see! I do nothing productive."

service.py

#near the top
from test1 import print_test
#lots of stuff here
print_test()

The following will order your data depending on both column in descending order.

ORDER BY article_rating DESC, article_time DESC

Calculating square roots by Newton's method is horrendously fast ... provided that the starting value is reasonable. However there is no reasonable starting value, and in practice we end with bisection and log(2^64) behaviour.
To be really fast we need a fast way to get at a reasonable starting value, and that means we need to descend into machine language. If a processor provides an instruction like POPCNT in the Pentium, that counts the leading zeroes we can use that to have a starting value with half the significant bits. With care we can find a a fixed number of Newton steps that will always suffice. (Thus foregoing the need to loop and have very fast execution.)

A second solution is going via the floating point facility, which may have a fast sqrt calculation (like the i87 coprocessor.) Even an excursion via exp() and log() may be faster than Newton degenerated into a binary search. There is a tricky aspect to this, a processor dependant analysis of what and if refinement afterwards is necessary.

A third solution solves a slightly different problem, but is well worth mentionning because the situation is described in the question. If you want to calculate a great many square roots for numbers that differ slightly, you can use Newton iteration, if you never reinitialise the starting value, but just leave it where the previous calculation left off. I've used this with success in at least one Euler problem.

I needed this for SQL Server. Here it is:

UPDATE user_account 
SET student_education_facility_id = cnt.education_facility_id
from  (
   SELECT user_account_id,education_facility_id
   FROM user_account 
   WHERE user_type = 'ROLE_TEACHER'
) as cnt
WHERE user_account.user_type = 'ROLE_STUDENT' and cnt.user_account_id = user_account.teacher_id

I think it works with other RDBMSes (please confirm). I like the syntax because it's extensible.

The format I needed was this actually:

UPDATE table1 
SET f1 = cnt.computed_column
from  (
   SELECT id,computed_column --can be any complex subquery
   FROM table1
) as cnt
WHERE cnt.id = table1.id

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

Evidently, sometimes, the display properties of parent of the element containing the matter that shouldn't overflow should also be set to overflow:hidden as well, e.g.:

<div style="overflow: hidden">
  <div style="overflow: hidden">some text that should not overflow<div>
</div>

Why? I have no idea but it worked for me. See https://medium.com/@crrollyson/overflow-hidden-not-working-check-the-child-element-c33ac0c4f565 (ignore the sniping at stackoverflow!)

In the end I made a jQuery plugin that will format the <input type="number" /> appropriately for me. I also noticed on some mobile devices the min and max attributes don't actually prevent you from entering lower or higher numbers than specified, so the plugin will account for that too. Below is the code and an example:

(function($) {_x000D_
  $.fn.currencyInput = function() {_x000D_
    this.each(function() {_x000D_
      var wrapper = $("<div class='currency-input' />");_x000D_
      $(this).wrap(wrapper);_x000D_
      $(this).before("<span class='currency-symbol'>$</span>");_x000D_
      $(this).change(function() {_x000D_
        var min = parseFloat($(this).attr("min"));_x000D_
        var max = parseFloat($(this).attr("max"));_x000D_
        var value = this.valueAsNumber;_x000D_
        if(value < min)_x000D_
          value = min;_x000D_
        else if(value > max)_x000D_
          value = max;_x000D_
        $(this).val(value.toFixed(2)); _x000D_
      });_x000D_
    });_x000D_
  };_x000D_
})(jQuery);_x000D_
_x000D_
$(document).ready(function() {_x000D_
  $('input.currency').currencyInput();_x000D_
});

.currency {_x000D_
  padding-left:12px;_x000D_
}_x000D_
_x000D_
.currency-symbol {_x000D_
  position:absolute;_x000D_
  padding: 2px 5px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<input type="number" class="currency" min="0.01" max="2500.00" value="25.00" />

Your updateVelocity() method is missing the explicit self parameter in its definition.

Should be something like this:

def updateVelocity(self):    
    for x in range(0,len(self.velocity)):
        self.velocity[x] = 2*random.random()*(self.pbestx[x]-self.current[x]) + 2 \
          * random.random()*(self.gbest[x]-self.current[x])

Your other methods (except for __init__) have the same problem.

You need to

using System.Linq;

to use IEnumerable options at your List.

enum ServicePlatform {
    UPLAY = "uplay",
    PSN = "psn",
    XBL = "xbl"
}

becomes:

{ UPLAY: 'uplay', PSN: 'psn', XBL: 'xbl' }

so

ServicePlatform.UPLAY in ServicePlatform // false

SOLUTION:

ServicePlatform.UPLAY.toUpperCase() in ServicePlatform // true

That's all you need:

#include <string>  //string::pop_back & string::empty

if (!st.empty())
    st.pop_back();

This can be solved by the following step:

Please ensure "Windows Hypervisor Platform" is installed. If it's not installed, install it, restart your computer and you will be good to go.

In this example we are creating a function to bring a comma delineated list of distinct line level AP invoice hold reasons into one field for header level query:

 FUNCTION getHoldReasonsByInvoiceId (p_InvoiceId IN NUMBER) RETURN VARCHAR2

  IS

  v_HoldReasons   VARCHAR2 (1000);

  v_Count         NUMBER := 0;

  CURSOR v_HoldsCusror (p2_InvoiceId IN NUMBER)
   IS
     SELECT DISTINCT hold_reason
       FROM ap.AP_HOLDS_ALL APH
      WHERE status_flag NOT IN ('R') AND invoice_id = p2_InvoiceId;
BEGIN

  v_HoldReasons := ' ';

  FOR rHR IN v_HoldsCusror (p_InvoiceId)
  LOOP
     v_Count := v_COunt + 1;

     IF (v_Count = 1)
     THEN
        v_HoldReasons := rHR.hold_reason;
     ELSE
        v_HoldReasons := v_HoldReasons || ', ' || rHR.hold_reason;
     END IF;
  END LOOP;

  RETURN v_HoldReasons;
END; 

I think the easiest way to do it is by using Requests module.

import requests

def url_ok(url):
    r = requests.head(url)
    return r.status_code == 200

var isImgLoaded = function(imgSelector){
  return $(imgSelector).prop("complete") && $(imgSelector).prop("naturalWidth") !== 0;
}

// Or As a Plugin

    $.fn.extend({
      isLoaded: function(){
        return this.prop("complete") && this.prop("naturalWidth") !== 0;
      }
    })

// $(".myImage").isLoaded() 

This happens to me, since I am designing my database, I notice that I change my seed on my main table, now the relational table has no foreign key on the main table.

So I need to truncate both tables, and it now works!

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

64/32 bit error? I found this as a problem as my dev machine was 32bit and the production server 64bit. If so, you may need to call the 32bit runtime directly from the command line.

This link says it better (No 64bit JET driver): http://social.msdn.microsoft.com/forums/en-US/sqlintegrationservices/thread/da076e51-8149-4948-add1-6192d8966ead/

The solution above not working for the latest version on PostgreSQL. I found this way to convert epoch time being stored in number and int column type is on PostgreSQL 13:

SELECT TIMESTAMP 'epoch' + (<table>.field::int) * INTERVAL '1 second' as started_on from <table>;

For more detail explanation, you can see here https://www.yodiw.com/convert-epoch-time-to-timestamp-in-postgresql/#more-214

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

To setup GruntJS build here is the steps:

1. Make sure you have setup your package.json or setup new one:

   npm init
   

2. Install Grunt CLI as global:

   npm install -g grunt-cli
   

3. Install Grunt in your local project:

   npm install grunt --save-dev
   

4. Install any Grunt Module you may need in your build process. Just for sake of this sample I will add Concat module for combining files together:

   npm install grunt-contrib-concat --save-dev
   

5. Now you need to setup your Gruntfile.js which will describe your build process. For this sample I just combine two JS files file1.js and file2.js in the js folder and generate app.js:

   module.exports = function(grunt) {
   
       // Project configuration.
       grunt.initConfig({
           concat: {
               "options": { "separator": ";" },
               "build": {
                   "src": ["js/file1.js", "js/file2.js"],
                   "dest": "js/app.js"
               }
           }
       });
   
       // Load required modules
       grunt.loadNpmTasks('grunt-contrib-concat');
   
       // Task definitions
       grunt.registerTask('default', ['concat']);
   };
   

6. Now you'll be ready to run your build process by following command:

   grunt
   

I hope this give you an idea how to work with GruntJS build.

NOTE:

You can use grunt-init for creating Gruntfile.js if you want wizard-based creation instead of raw coding for step 5.

To do so, please follow these steps:

npm install -g grunt-init
git clone https://github.com/gruntjs/grunt-init-gruntfile.git ~/.grunt-init/gruntfile
grunt-init gruntfile

For Windows users: If you are using cmd.exe you need to change ~/.grunt-init/gruntfile to %USERPROFILE%\.grunt-init\. PowerShell will recognize the ~ correctly.

You should use Array.prototype.reduce to do this. I did do a little JS perf test to verify that this is more performant than doing a .filter + .map.

$scope.appIds = $scope.applicationsHere.reduce(function(ids, obj){
    if(obj.selected === true){
        ids.push(obj.id);
    }
    return ids;
}, []);

Just for the sake of clarity, here's the sample .reduce I used in the JSPerf test:

  var things = [_x000D_
    {id: 1, selected: true},_x000D_
    {id: 2, selected: true},_x000D_
    {id: 3, selected: true},_x000D_
    {id: 4, selected: true},_x000D_
    {id: 5, selected: false},_x000D_
    {id: 6, selected: true},_x000D_
    {id: 7, selected: false},_x000D_
    {id: 8, selected: true},_x000D_
    {id: 9, selected: false},_x000D_
    {id: 10, selected: true},_x000D_
  ];_x000D_
  _x000D_
   _x000D_
var ids = things.reduce((ids, thing) => {_x000D_
  if (thing.selected) {_x000D_
    ids.push(thing.id);_x000D_
  }_x000D_
  return ids;_x000D_
}, []);_x000D_
_x000D_
console.log(ids)

EDIT 1

Note, As of 2/2018 Reduce + Push is fastest in Chrome and Edge, but slower than Filter + Map in Firefox

Let's say you have this data setup (so that results are reproducible):

// declaring data types
case class Company(cName: String, cId: String, details: String)
case class Employee(name: String, id: String, email: String, company: Company)

// setting up example data
val e1 = Employee("n1", null, "[email protected]", Company("c1", "1", "d1"))
val e2 = Employee("n2", "2", "[email protected]", Company("c1", "1", "d1"))
val e3 = Employee("n3", "3", "[email protected]", Company("c1", "1", "d1"))
val e4 = Employee("n4", "4", "[email protected]", Company("c2", "2", "d2"))
val e5 = Employee("n5", null, "[email protected]", Company("c2", "2", "d2"))
val e6 = Employee("n6", "6", "[email protected]", Company("c2", "2", "d2"))
val e7 = Employee("n7", "7", "[email protected]", Company("c3", "3", "d3"))
val e8 = Employee("n8", "8", "[email protected]", Company("c3", "3", "d3"))
val employees = Seq(e1, e2, e3, e4, e5, e6, e7, e8)
val df = sc.parallelize(employees).toDF

Data is:

+----+----+---------+---------+
|name|  id|    email|  company|
+----+----+---------+---------+
|  n1|null|[email protected]|[c1,1,d1]|
|  n2|   2|[email protected]|[c1,1,d1]|
|  n3|   3|[email protected]|[c1,1,d1]|
|  n4|   4|[email protected]|[c2,2,d2]|
|  n5|null|[email protected]|[c2,2,d2]|
|  n6|   6|[email protected]|[c2,2,d2]|
|  n7|   7|[email protected]|[c3,3,d3]|
|  n8|   8|[email protected]|[c3,3,d3]|
+----+----+---------+---------+

Now to filter employees with null ids, you will do --

df.filter("id is null").show

which will correctly show you following:

+----+----+---------+---------+
|name|  id|    email|  company|
+----+----+---------+---------+
|  n1|null|[email protected]|[c1,1,d1]|
|  n5|null|[email protected]|[c2,2,d2]|
+----+----+---------+---------+

Coming to the second part of your question, you can replace the null ids with 0 and other values with 1 with this --

df.withColumn("id", when($"id".isNull, 0).otherwise(1)).show

This results in:

+----+---+---------+---------+
|name| id|    email|  company|
+----+---+---------+---------+
|  n1|  0|[email protected]|[c1,1,d1]|
|  n2|  1|[email protected]|[c1,1,d1]|
|  n3|  1|[email protected]|[c1,1,d1]|
|  n4|  1|[email protected]|[c2,2,d2]|
|  n5|  0|[email protected]|[c2,2,d2]|
|  n6|  1|[email protected]|[c2,2,d2]|
|  n7|  1|[email protected]|[c3,3,d3]|
|  n8|  1|[email protected]|[c3,3,d3]|
+----+---+---------+---------+

Swift version:

    static func imageWithImage(image:UIImage, newSize:CGSize) ->UIImage {
    UIGraphicsBeginImageContextWithOptions(newSize, true, UIScreen.mainScreen().scale);
    image.drawInRect(CGRectMake(0, 0, newSize.width, newSize.height))

    let newImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();
    return newImage
}

You can simply call the RoundedCornersTransformation constructor, which has cornerType enum input. Like this:

Glide.with(context)
            .load(bizList.get(position).getCover())
            .bitmapTransform(new RoundedCornersTransformation(context,20,0, RoundedCornersTransformation.CornerType.TOP))
            .into(holder.bizCellCoverImg);

but first you have to add Glide Transformations to your project.

How about this: I used it with a mixin

non-compliant object

@Entity
@Getter
@NoArgsConstructor
public class Telemetry {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long pk;
    private String id;
    private String organizationId;
    private String baseType;
    private String name;
    private Double lat;
    private Double lon;
    private Instant updateTimestamp;
}

Mixin:

@JsonAutoDetect(fieldVisibility = ANY, getterVisibility = NONE, setterVisibility = NONE)
public static class TelemetryMixin {}

Usage:

    ObjectMapper om = objectMapper.addMixIn(Telemetry.class, TelemetryMixin.class);
    Telemetry[] telemetries = om.readValue(someJson, Telemetry[].class);

There is nothing that says you couldn't foreach any number of classes and apply the same mixin.

If you're not familiar with mixins, they are conceptually simply: The structure of the mixin is super imposed on the target class (according to jackson, not as far as the JVM is concerned).

another way of doing it :)

return ((b >> bitNumber) & 1) != 0;

What works for me was with one dot. Mine Office is 365. =HYPERLINK(".\Name_of_folder\","DisplayLinkName") =HYPERLINK(".\Name_of_file","DisplayLinkName")

There is also a GUI tool that allows visual JKS creation and certificates importing.

http://portecle.sourceforge.net/

Portecle is a user friendly GUI application for creating, managing and examining keystores, keys, certificates, certificate requests, certificate revocation lists and more.

If you can count on having a period of time where the table is in a stable state with no new inserts going on, this should do it (untested):

DECLARE
  last_used  NUMBER;
  curr_seq   NUMBER;
BEGIN
  SELECT MAX(pk_val) INTO last_used FROM your_table;

  LOOP
    SELECT your_seq.NEXTVAL INTO curr_seq FROM dual;
    IF curr_seq >= last_used THEN EXIT;
    END IF;
  END LOOP;
END;

This enables you to get the sequence back in sync with the table, without dropping/recreating/re-granting the sequence. It also uses no DDL, so no implicit commits are performed. Of course, you're going to have to hunt down and slap the folks who insist on not using the sequence to populate the column...

If you are getting this error with a Java configuration, it is usually because you forget to pass in the application context to the DispatcherServlet constructor:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet()); // <-- no constructor args!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

Fix it by adding the context as the constructor arg:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet(ctx)); // <-- hooray! Spring doesn't look for XML files!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

In jQuery it would be as simple as $('#yourDivID').empty()

See the documentation.

I came across this question looking for an answer in the context of checking for the Visual C++ redistributable as part of an MSI installer created by WiX.

I didn't like how the GUID's change with version and operating system, so I ended up creating a custom action written in C# to check for the Visual C++ redistributable.

Everything below is specifically for Visual C++ 2015 Redistributable (x64), but it can be easily modified for any version.

using Microsoft.Deployment.WindowsInstaller;
using Microsoft.Win32;

namespace CustomActions
{
    public class DependencyChecks
    {
        [CustomAction]
        public static ActionResult IsVC2015RedistInstalled(Session session)
        {
            session.Log("Begin Visual C++ 2015 Redistributable installation check.");

            var dependenciesKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Classes\\Installer\\Dependencies");

            foreach(var subKey in dependenciesKey.GetSubKeyNames())
            {
                var dependency = dependenciesKey.OpenSubKey(subKey);
                var displayName = (string)dependency.GetValue("DisplayName");
                if(displayName != null)
                {
                    if (displayName.Contains("Microsoft Visual C++ 2015 Redistributable (x64)"))
                    {
                        session.Log("Visual C++ 2015 Redistributable is installed.");
                        return ActionResult.Success;
                    }
                }
            }

            session.Log("Visual C++ 2015 Redistributable is not installed.");
            session.Message(InstallMessage.Error, new Record(1, "This application requires Visual C++ 2015 Redistributable. Please install, then run this installer again. https://www.microsoft.com/en-us/download/details.aspx?id=53587"));
            return ActionResult.Failure;
        }
    }
}

Then in the wxs file

<Binary Id='VC2015RedistCheck' SourceFile='!(wix.ResourcesDir=resources)\CustomActions.CA.dll'/>
    <CustomAction
      Id='VC2015RedistCheckAction'
      Execute='immediate'
      BinaryKey='VC2015RedistCheck'
      DllEntry="IsVC2015RedistInstalled"
      Return='check'/>

<InstallExecuteSequence>
  <Custom Action='VC2015RedistCheckAction' After='InstallInitialize'/>
</InstallExecuteSequence>

Edit I'm updating this answer with some basic info on creating and using a custom action.

To create the custom action in Visual Studio 2017 with the WiX Toolset Visual Studio 2017 extension installed, I used the project template to create a custom action (C# Custom Action Project for WiX v3).

I checked the generated project and it seemed to already have the changes listed at the beginning of this article: https://www.codeproject.com/Articles/132918/Creating-Custom-Action-for-WIX-Written-in-Managed so I picked that article up at the section Adding Custom Action to the Installer and followed it through with some tweaks.

One other thing that I did was change the version of the .NET framework the project is built against to 3.5.

I didn't find it really useful but you can also see http://wixtoolset.org/documentation/manual/v3/wixdev/extensions/authoring_custom_actions.html

It is better to avoid using mod_rewrite when you can.

In your case I would replace the Rewrite with this:

    <If "%{HTTPS} == 'on'" >
            Redirect permanent / http://production_server/
    </If>

The <If> directive is only available in Apache 2.4+ as per this blog here.

Easiest way to do this is close the project. Using file explorer head to the location of that project and delete.

Alot of processes, even simply deleting can be annoying to figure out in studio. Most deleting options a good work around is to delete using file explorer. This is a part of the process tht works for deleting modules as well. Which u will prob find is painful as well

There is a tool from Microsoft to convert java to C#. For the opposite direction take a look here and here. If this doesn't work out, it should not take too long to convert the source manually because C# and java are very similar,

getFilesDir()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

Environment.getDataDirectory()

Return the user data directory.

Sample XML:

<X>
<Y ATTRIB1=attrib1_value ATTRIB2=attrib2_value/>
</X>

string xPath="/" + X + "/" + Y +
"[@" + ATTRIB1 + "='" + attrib1_value + "']" +
"[@" + ATTRIB2 + "='" + attrib2_value + "']"

When you export you use the compatibility system set to MYSQL40. Worked for me.

Turned out there was some extra code in the AppModel that was messing things up:

in beforeFind and afterFind:

App::Import("Session");
$session = new CakeSession();
$sim_id = $session->read("Simulation.id");

I don't know why, but that was what the problem was. Removing those lines fixed the issue I was having.

I guess what you need is np.set_printoptions(suppress=True), for details see here: http://pythonquirks.blogspot.fr/2009/10/controlling-printing-in-numpy.html

For SciPy.org numpy documentation, which includes all function parameters (suppress isn't detailed in the above link), see here: https://docs.scipy.org/doc/numpy/reference/generated/numpy.set_printoptions.html

With your requirements you don't need BEGIN END and IF with unnecessary SELECT in your trigger. So you can simplify it to this

CREATE TRIGGER occupy_trig AFTER INSERT ON occupiedroom 
FOR EACH ROW
  UPDATE BookingRequest
     SET status = 1
   WHERE idRequest = NEW.idRequest;

I think the most efficient way to do this is this is using RemoveAt:

rows.RemoveAt(rows.Count - 1)

Please Search Google given to the world by Larry Page and Sergey Brin.

BufferedWriter out = null;

try {
    FileWriter fstream = new FileWriter("out.txt", true); //true tells to append data.
    out = new BufferedWriter(fstream);
    out.write("\nsue");
}

catch (IOException e) {
    System.err.println("Error: " + e.getMessage());
}

finally {
    if(out != null) {
        out.close();
    }
}

It looks like you indented so_far = new too much. Try this:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
    so_far = new # unindented this

Great then. Let's create a simple function that takes an array and prints our an ordered listview/list inside a div tag.

Step 1: Let's say you have an div with "contentSectionID" id.<div id="contentSectionID"></div>

Step 2: We then create our javascript function that returns a list component and takes in an array:

function createList(spacecrafts){

var listView=document.createElement('ol');

for(var i=0;i<spacecrafts.length;i++)
{
    var listViewItem=document.createElement('li');
    listViewItem.appendChild(document.createTextNode(spacecrafts[i]));
    listView.appendChild(listViewItem);
}

return listView;
}

Step 3: Finally we select our div and create a listview in it:

document.getElementById("contentSectionID").appendChild(createList(myArr));

As @Quartz mentioned, you can do something like

stage('Tests') {
    parallel(
        'Unit Tests': {
            container('node') {
                sh("npm test --cat=unit")
            }
        },
        'API Tests': {
            container('node') {
                sh("npm test --cat=acceptance")
            }
        }
    )
}

As an alternative solution, I'm using this one on Mac OSX 10.7.5

grep -ilr 'old-word' * | xargs -I@ sed -i '' 's/old-word/new-word/g' @

Your problem is those pernicious double quotes.

SQL> CREATE TABLE "APC"."PS_TBL_DEPARTMENT_DETAILS"
  2  (
  3    "Company Code" VARCHAR2(255),
  4    "Company Name" VARCHAR2(255),
  5    "Sector_Code" VARCHAR2(255),
  6    "Sector_Name" VARCHAR2(255),
  7    "Business_Unit_Code" VARCHAR2(255),
  8    "Business_Unit_Name" VARCHAR2(255),
  9    "Department_Code" VARCHAR2(255),
 10    "Department_Name" VARCHAR2(255),
 11    "HR_ORG_ID" VARCHAR2(255),
 12    "HR_ORG_Name" VARCHAR2(255),
 13    "Cost_Center_Number" VARCHAR2(255),
 14    " " VARCHAR2(255)
 15  )
 16  /

Table created.

SQL>

Oracle SQL allows us to ignore the case of database object names provided we either create them with names all in upper case, or without using double quotes. If we use mixed case or lower case in the script and wrapped the identifiers in double quotes we are condemned to using double quotes and the precise case whenever we refer to the object or its attributes:

SQL> select count(*) from PS_TBL_DEPARTMENT_DETAILS
  2  where Department_Code = 'BAH'
  3  /
where Department_Code = 'BAH'
      *
ERROR at line 2:
ORA-00904: "DEPARTMENT_CODE": invalid identifier


SQL> select count(*) from PS_TBL_DEPARTMENT_DETAILS
  2  where "Department_Code" = 'BAH'
  3  /

  COUNT(*)
----------
         0

SQL>

tl;dr

don't use double quotes in DDL scripts

(I know most third party code generators do, but they are disciplined enough to put all their object names in UPPER CASE.)

The reverse is also true. If we create the table without using double-quotes …

create table PS_TBL_DEPARTMENT_DETAILS
( company_code VARCHAR2(255),
  company_name VARCHAR2(255),
  Cost_Center_Number VARCHAR2(255))
;

… we can reference it and its columns in whatever case takes our fancy:

select * from ps_tbl_department_details

… or

select * from PS_TBL_DEPARTMENT_DETAILS;

… or

select * from PS_Tbl_Department_Details
where COMAPNY_CODE = 'ORCL'
and cost_center_number = '0980'

You can also get your wanted time using the following JS code:

new Date(`${post.data.created_at} GMT+0200`)

In this example, my received dates were in GMT+0200 timezone. Instead of it can be every single timezone. And the returned data will be the date in your timezone. Hope this will help anyone to save time

VT-x can normally be disabled/enabled in your BIOS.

When your PC is just starting up you should press DEL (or something) to get to the BIOS settings. There you'll find an option to enable VT-technology (or something).

You can fetch the list of tables and schemata by querying the SQLITE_MASTER table:

sqlite> .tab
job         snmptarget  t1          t2          t3        
sqlite> select name from sqlite_master where type = 'table';
job
t1
t2
snmptarget
t3

sqlite> .schema job
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
);
sqlite> select sql from sqlite_master where type = 'table' and name = 'job';
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
)

How to write a basic PHP Ternary Operator:

($your_boolean) ? 'This is returned if true' : 'This is returned if false';

Example:

$myboolean = true;
echo ($myboolean) ? 'foobar' : "penguin";
foobar

echo (!$myboolean) ? 'foobar' : "penguin";
penguin

A PHP ternary operator with an 'elseif' crammed in there:

$chow = 3;
echo ($chow == 1) ? "one" : ($chow == 2) ? "two" : "three";
three

But please don't nest ternary operators except for parlor tricks. It's a bad code smell.

The point seems to be that sometimes, you need a property that has automatic storage and some behavior, for instance to notify other objects that the property just changed. When all you have is get/set, you need another field to hold the value. With willSet and didSet, you can take action when the value is modified without needing another field. For instance, in that example:

class Foo {
    var myProperty: Int = 0 {
        didSet {
            print("The value of myProperty changed from \(oldValue) to \(myProperty)")
        }
    }
}

myProperty prints its old and new value every time it is modified. With just getters and setters, I would need this instead:

class Foo {
    var myPropertyValue: Int = 0
    var myProperty: Int {
        get { return myPropertyValue }
        set {
            print("The value of myProperty changed from \(myPropertyValue) to \(newValue)")
            myPropertyValue = newValue
        }
    }
}

So willSet and didSet represent an economy of a couple of lines, and less noise in the field list.

This worked for me -

    <?xml version="1.0" encoding="utf-8" ?>
<project name="test" default="compile">
    <target name="compile">
        <javac srcdir="src" destdir="classes" 
                           encoding="iso-8859-1" debug="true" />
    </target>
</project>

Open terminal (in Unix, in MAC), (cmd in Windows) and cd to this (your java) path:

C:\Program Files\Java\jdk1.6.0_43\bin>

Run this command:

keytool -list -v -keystore C:\Users\leon\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

Just change the path to debug.keystore and you will get both MD5 and SHA-1 fingerprints.

See this TechNet article: Runas command documentation

From a command prompt:

C:\> runas /user:<localmachinename>\administrator cmd

Or, if you're connected to a domain:

C:\> runas /user:<DomainName>\<AdministratorAccountName> cmd

Any Activity that restarts has its onResume() method executed first.

To use this method, do this:

@Override
public void onResume(){
    super.onResume();
    // put your code here...

}

If you read the help file for ?boxplot, you'll see there is a names= parameter.

     boxplot(apple, banana, watermelon, names=c("apple","banana","watermelon"))

try this:

var maxid = from i in items
            group i by i.clientid int g
            select new { id = g.Max(i=>i.ID }

Let's answer your questions one by one.

1. Yes, you make a new object whenever this statement is executed, however, it goes "out of scope" when you exit the method and it is eligible for garbage collection.
2. Well this would be the same as #1, except that you've used a string type. A string type is immutable and you get a new object every time you make an assignment.
3. Yes the garbage collector collects the out of scope objects, unless you assign the object to a variable with a large scope such as class variable.
4. Yes.
5. The using statement only applies to objects that implement the IDisposable interface. If that is the case, by all means using is best for objects within a method's scope. Don't put Foo o at a larger scope unless you have a good reason to do so. It is best to limit the scope of any variable to the smallest scope that makes sense.

Have a look at GNU datamash which can be used like datamash transpose. A future version will also support cross tabulation (pivot tables)

Here is how you would do it with space separated columns:

datamash transpose -t ' ' < file > transposed_file

try

el.css('margin-left',mrg+'px');

You need a ResourceLink in your META-INF/context.xml file to make the global resource available to the web application.

 <ResourceLink name="jdbc/mydb"
             global="jdbc/mydb"
              type="javax.sql.DataSource" />

You should put the script as argument for a *NIX shell you run, equivalent to the *NIXish

sh myscriptfile

If You have no access to plugin for instance outside of controller You can get params from servicelocator like this

//from POST
$foo = $this->serviceLocator->get('request')->getPost('foo'); 
//from GET
$foo = $this->serviceLocator->get('request')->getQuery()->foo;
//from route
$foo = $this->serviceLocator->get('application')->getMvcEvent()->getRouteMatch()->getParam('foo');

The resolution of DateTime.Now depends on your system timer (~10ms on a current Windows OS)...so it's giving the same ending value there (it doesn't count any more finite than that).

Hack solution

You can read the text file into a String var. Then split the String into an array using a single whitespace as the delimiter StringVar.Split(" ").

The Array count would equal the number of "Words" in the file. Of course this wouldnt give you a count of line numbers.

the return type of object.equals is already boolean. there's no need to wrap it in a method with branches. so if you want to compare 2 objects simply compare them:

boolean b = objectA.equals(objectB);

b is already either true or false.

This is not how you initialize an array, but for:

1. The first declaration:

   char buf[10] = "";
   

   is equivalent to

   char buf[10] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
   

2. The second declaration:

   char buf[10] = " ";
   

   is equivalent to

   char buf[10] = {' ', 0, 0, 0, 0, 0, 0, 0, 0, 0};
   

3. The third declaration:

   char buf[10] = "a";
   

   is equivalent to

   char buf[10] = {'a', 0, 0, 0, 0, 0, 0, 0, 0, 0};
   

As you can see, no random content: if there are fewer initializers, the remaining of the array is initialized with 0. This the case even if the array is declared inside a function.

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

For android 19+ you can get it in Telephony.Sms.Intents.SMS_RECEIVED_ACTION). There are more in the Intents class that 're worth looking at

I just can't believe that there are people still using ViewData/ViewBag in ASP.NET MVC 3 instead of having strongly typed views and view models:

public class MyViewModel
{
    [Required]
    public string CategoryId { get; set; }

    public IEnumerable<Category> Categories { get; set; }
}

and in your controller:

public class HomeController: Controller
{
    public ActionResult Index()
    {
        var model = new MyViewModel
        {
            Categories = Repository.GetCategories()
        }
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        if (!ModelState.IsValid)
        {
            // there was a validation error =>
            // rebind categories and redisplay view
            model.Categories = Repository.GetCategories();
            return View(model);
        }
        // At this stage the model is OK => do something with the selected category
        return RedirectToAction("Success");
    }
}

and then in your strongly typed view:

@Html.DropDownListFor(
    x => x.CategoryId, 
    new SelectList(Model.Categories, "ID", "CategoryName"), 
    "-- Please select a category --"
)
@Html.ValidationMessageFor(x => x.CategoryId)

Also if you want client side validation don't forget to reference the necessary scripts:

<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

If you already use jitpack.io or any repository. You can add google repository like this:

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
        maven { url "https://maven.google.com" }
    }
}

It's not as easy as it seems to implement a control like that. Explorer works with shell items, not filesystem items (ex: the control panel, the printers folder, and so on). If you need to implement it i suggest to have a look at the Windows shell functions at http://msdn.microsoft.com/en-us/library/bb776426(VS.85).aspx.

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

I understand the question is regarding UBUNTU, but I had similar problem in Debian Jessie 64bit and warsongs suggestion worked for it also.
When I ran studio.sh android studio would start, but when I tried to configure the android SDK I got the error
Unable to run mksdcard SDK tool
WHen I tried
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
Got error
E: Package 'lib32bz2-1.0' has no installation candidate
So took warsongs suggestion and only tried to install lib32stdc++6.
sudo apt-get install lib32stdc++6
After this was able to add the Android SDK into Android Studio.

The hold on feature is switched on by default in matplotlib.pyplot. So each time you evoke plt.plot() before plt.show() a drawing is added to the plot. Launching plt.plot() after the function plt.show() leads to redrawing the whole picture.

For those who use mybatis, here is an example update statement:

<update id="saveAnswer">
    update quiz_execution set answer_data = jsonb_set(answer_data, concat('{', #{qid}, '}')::text[], #{value}::jsonb), updated_at = #{updatedAt}

In addition to tcash21's numeric indexing if OP may have been looking for negative indexing by name. Here's a few ways I know, some are risky than others to use:

mtcars[, -which(names(mtcars) == "carb")]  #only works on a single column
mtcars[, names(mtcars) != "carb"]          #only works on a single column
mtcars[, !names(mtcars) %in% c("carb", "mpg")] 
mtcars[, -match(c("carb", "mpg"), names(mtcars))] 
mtcars2 <- mtcars; mtcars2$hp <- NULL         #lost column (risky)


library(gdata) 
remove.vars(mtcars2, names=c("mpg", "carb"), info=TRUE) 

Generally I use:

mtcars[, !names(mtcars) %in% c("carb", "mpg")] 

because I feel it's safe and efficient.

Windows 10 x64 released August 2015 - same issue arising. MSVCR110.dll is also found in the sysWOW64 folder (which is where I found it, copying to system32 does not help). To resolve:

1. uninstall the x86 versions of VC 11 vcredist_x64/86.exe for 2012 and 2013
2. uninstall WAMP Server 2.5
3. delete (maybe back up first) the WAMP folder
4. restart windows
5. reinstall WAMP 2.5

Hopefully like me you have a MySQL database backup handy!

Your use of @PathParam is incorrect. It does not follow these requirements as documented in the javadoc here. I believe you just want to POST the JSON entity. You can fix this in your resource method to accept JSON entity.

@Path("/hello")
public class Hello {

  @POST
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.APPLICATION_JSON)
  public JSONObject sayPlainTextHello(JSONObject inputJsonObj) throws Exception {

    String input = (String) inputJsonObj.get("input");
    String output = "The input you sent is :" + input;
    JSONObject outputJsonObj = new JSONObject();
    outputJsonObj.put("output", output);

    return outputJsonObj;
  }
}

And, your client code should look like this:

  ClientConfig config = new DefaultClientConfig();
  Client client = Client.create(config);
  client.addFilter(new LoggingFilter());
  WebResource service = client.resource(getBaseURI());
  JSONObject inputJsonObj = new JSONObject();
  inputJsonObj.put("input", "Value");
  System.out.println(service.path("rest").path("hello").accept(MediaType.APPLICATION_JSON).post(JSONObject.class, inputJsonObj));

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")

root.mainloop()

SELECT TOP 1 column_name, LEN(column_name) AS Lenght FROM table_name ORDER BY LEN(column_name) DESC

You can also use

./gradlew clean build (Mac and Linux) -With ./

gradlew clean build (Windows) -Without ./

it removes build folder, as well configure your modules and then build your project.

i use it before release any new app on playstore.

Here is a function that does the conversion of a PDF file with one or multiple pages to a single merged JPEG image.

import os
import tempfile
from pdf2image import convert_from_path
from PIL import Image

def convert_pdf_to_image(file_path, output_path):
    # save temp image files in temp dir, delete them after we are finished
    with tempfile.TemporaryDirectory() as temp_dir:
        # convert pdf to multiple image
        images = convert_from_path(file_path, output_folder=temp_dir)
        # save images to temporary directory
        temp_images = []
        for i in range(len(images)):
            image_path = f'{temp_dir}/{i}.jpg'
            images[i].save(image_path, 'JPEG')
            temp_images.append(image_path)
        # read images into pillow.Image
        imgs = list(map(Image.open, temp_images))
    # find minimum width of images
    min_img_width = min(i.width for i in imgs)
    # find total height of all images
    total_height = 0
    for i, img in enumerate(imgs):
        total_height += imgs[i].height
    # create new image object with width and total height
    merged_image = Image.new(imgs[0].mode, (min_img_width, total_height))
    # paste images together one by one
    y = 0
    for img in imgs:
        merged_image.paste(img, (0, y))
        y += img.height
    # save merged image
    merged_image.save(output_path)
    return output_path

Example usage: -

convert_pdf_to_image("path_to_Pdf/1.pdf", "output_path/output.jpeg")

The accepted answer was great solution for me. The only thing to add is about inflate() method.

In accepted answer all android:layout_* parameters will not be applied.

The reason is no way to adjust it, cause null was passed as ViewGroup parent.

You can use it like this:

View view = inflater.inflate(R.layout.view, parent, false);

and the parent is the ViewGroup, from where you like to adjust android:layout_*.

In this case, all relative properties will be set.

Hope it'll be useful for someone.

I'm not sure what level of accuracy you need, but what I would do is simply add 1 the first n numbers, n being the ceil of the total sum of decimals. In this case that is 3, so I would add 1 to the first 3 items and floor the rest. Of course this is not super accurate, some numbers might be rounded up or down when it shouldn't but it works okay and will always result in 100%.

So [ 13.626332, 47.989636, 9.596008, 28.788024 ] would be [14, 48, 10, 28] because Math.ceil(.626332+.989636+.596008+.788024) == 3

function evenRound( arr ) {
  var decimal = -~arr.map(function( a ){ return a % 1 })
    .reduce(function( a,b ){ return a + b }); // Ceil of total sum of decimals
  for ( var i = 0; i < decimal; ++i ) {
    arr[ i ] = ++arr[ i ]; // compensate error by adding 1 the the first n items
  }
  return arr.map(function( a ){ return ~~a }); // floor all other numbers
}

var nums = evenRound( [ 13.626332, 47.989636, 9.596008, 28.788024 ] );
var total = nums.reduce(function( a,b ){ return a + b }); //=> 100

You can always inform users that the numbers are rounded and may not be super-accurate...

You can check the package leaps and in particular the function regsubsets() functions for model selection. As stated in the documentation:

Model selection by exhaustive search, forward or backward stepwise, or sequential replacement

I was plagued by this error message despite using async: true. It turns out the actual problem was using the success method. I changed this to done and warning is gone.

success: function(response) { ... }

replaced with:

done: function(response) { ... }

The following tsconfig setting will allow you to ignore these errors - set it to true.

suppressImplicitAnyIndexErrors

Suppress noImplicitAny errors for indexing objects lacking index signatures.

printf(...) is equivalent to fprintf(stdout,...).

fprintf is used to output to stream.

sprintf(buffer,...) is used to format a string to a buffer.

Note there is also vsprintf, vfprintf and vprintf

This error can get thrown if your data frame has sf geometry columns.

Here is a comprehensive recursive function (originally based on the one by @chickens) that will:

• recursively remove what you tell it to defaults=[undefined, null, '', NaN]
• Correctly handle regular objects, arrays and Date objects

const cleanEmpty = function(obj, defaults = [undefined, null, NaN, '']) {
  if (!defaults.length) return obj
  if (defaults.includes(obj)) return

  if (Array.isArray(obj))
    return obj
      .map(v => v && typeof v === 'object' ? cleanEmpty(v, defaults) : v)
      .filter(v => !defaults.includes(v))

  return Object.entries(obj).length 
    ? Object.entries(obj)
        .map(([k, v]) => ([k, v && typeof v === 'object' ? cleanEmpty(v, defaults) : v]))
        .reduce((a, [k, v]) => (defaults.includes(v) ? a : { ...a, [k]: v}), {}) 
    : obj
}

This worked for me on my Oracle database:

SELECT   'GRANT SELECT, insert, update, delete ON mySchema.' || TABLE_NAME || ' to myUser;'
FROM     user_tables
where table_name like 'myTblPrefix%'

Then, copy the results, paste them into your editor, then run them like a script.

You could also write a script and use "Execute Immediate" to run the generated SQL if you don't want the extra copy/paste steps.

$(document).ready(function () {_x000D_

Fluid layout in Bootstrap 3.

Unlike Boostrap 2, Bootstrap 3 doesn't have a .container-fluid mixin to make a fluid container. The .container is a fixed width responsive grid layout. In a large screen, there are excessive white spaces in both sides of one's Web page content.

container-fluid is added back in Bootstrap 3.1

A fluid grid layout uses all screen width and works better in large screen. It turns out that it is easy to create a fluid grid layout using Bootstrap 3 mixins. The following line makes a fluid responsive grid layout:

.container-fixed;

The .container-fixed mixin sets the content to the center of the screen and add paddings. It doesn't specifies a fixed page width.

Another approach is to use Eric Flowers' CSS style

.my-fluid-container {
    padding-left: 15px;
    padding-right: 15px;
    margin-left: auto;
    margin-right: auto;
}

EDIT (2018): The edited sibling answer by @xinyongCheng is a simpler approach, and should be the accepted answer.

Your approach would be reasonable if you knew the bytes are in the platform's default charset. In your example, this is true because k.getBytes() returns the bytes in the platform's default charset.

More frequently, you'll want to specify the encoding. However, there's a simpler way to do that than the question you linked. The String API provides methods that converts between a String and a byte[] array in a particular encoding. These methods suggest using CharsetEncoder/CharsetDecoder "when more control over the decoding [encoding] process is required."

To get the bytes from a String in a particular encoding, you can use a sibling getBytes() method:

byte[] bytes = k.getBytes( StandardCharsets.UTF_8 );

To put bytes with a particular encoding into a String, you can use a different String constructor:

String v = new String( bytes, StandardCharsets.UTF_8 );

Note that ByteBuffer.array() is an optional operation. If you've constructed your ByteBuffer with an array, you can use that array directly. Otherwise, if you want to be safe, use ByteBuffer.get(byte[] dst, int offset, int length) to get bytes from the buffer into a byte array.

I found a workaround.

1. Export with a white background (or other color that will work with transparent graphics). This will be out "whitescreen" layer.
2. Export with "bluescreen" background, or some terrible other color that will make it easy to select out the background from foreground.
3. Open the bluescreen version as a layer on top of the white screen.
4. Use the bluescreen layer to select out only the parts you want to use.
5. Create a mask for the whitescreen layer with the selection made from the bluescreen layer.

This will get good results for edges and aliasing, whilst retaining a good color for the see-

if all you're trying to do is get the value of a single entry in a map, there's no need to loop over any collection at all. simplifying gautum's response slightly, you can get the value of a named map entry as follows:

<c:out value="${map['key']}"/>

where 'map' is the collection and 'key' is the string key for which you're trying to extract the value.

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

One thing to note is that ngModel is required for ngOptions to work... note the ng-model="blah" which is saying "set $scope.blah to the selected value".

Try this:

<select ng-model="blah" ng-options="item.ID as item.Title for item in items"></select>

Here's more from AngularJS's documentation (if you haven't seen it):

for array data sources:

• label for value in array
• select as label for value in array
• label group by group for value in array = select as label group by group for value in array

for object data sources:

• label for (key , value) in object
• select as label for (key , value) in object
• label group by group for (key, value) in object
• select as label group by group for (key, value) in object

For some clarification on option tag values in AngularJS:

When you use ng-options, the values of option tags written out by ng-options will always be the index of the array item the option tag relates to. This is because AngularJS actually allows you to select entire objects with select controls, and not just primitive types. For example:

app.controller('MainCtrl', function($scope) {
   $scope.items = [
     { id: 1, name: 'foo' },
     { id: 2, name: 'bar' },
     { id: 3, name: 'blah' }
   ];
});

<div ng-controller="MainCtrl">
   <select ng-model="selectedItem" ng-options="item as item.name for item in items"></select>
   <pre>{{selectedItem | json}}</pre>
</div>

The above will allow you to select an entire object into $scope.selectedItem directly. The point is, with AngularJS, you don't need to worry about what's in your option tag. Let AngularJS handle that; you should only care about what's in your model in your scope.

Here is a plunker demonstrating the behavior above, and showing the HTML written out

Dealing with the default option:

There are a few things I've failed to mention above relating to the default option.

Selecting the first option and removing the empty option:

You can do this by adding a simple ng-init that sets the model (from ng-model) to the first element in the items your repeating in ng-options:

<select ng-init="foo = foo || items[0]" ng-model="foo" ng-options="item as item.name for item in items"></select>

Note: This could get a little crazy if foo happens to be initialized properly to something "falsy". In that case, you'll want to handle the initialization of foo in your controller, most likely.

Customizing the default option:

This is a little different; here all you need to do is add an option tag as a child of your select, with an empty value attribute, then customize its inner text:

<select ng-model="foo" ng-options="item as item.name for item in items">
   <option value="">Nothing selected</option>
</select>

Note: In this case the "empty" option will stay there even after you select a different option. This isn't the case for the default behavior of selects under AngularJS.

A customized default option that hides after a selection is made:

If you wanted your customized default option to go away after you select a value, you can add an ng-hide attribute to your default option:

<select ng-model="foo" ng-options="item as item.name for item in items">
   <option value="" ng-if="foo">Select something to remove me.</option>
</select>

Another alternative is to use capturing sub-expressions with the regular expression functions regmatches and regexec.

# the original example
x <- 'hello stackoverflow'

# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', x))

This returns the entire string, the first character, and the "popped" result in a list of length 1.

myStrings
[[1]]
[1] "hello stackoverflow" "h"                   "ello stackoverflow" 

which is equivalent to list(c(x, substr(x, 1, 1), substr(x, 2, nchar(x)))). That is, it contains the super set of the desired elements as well as the full string.

Adding sapply will allow this method to work for a character vector of length > 1.

# a slightly more interesting example
xx <- c('hello stackoverflow', 'right back', 'at yah')

# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', xx))

This returns a list with the matched full string as the first element and the matching subexpressions captured by () as the following elements. So in the regular expression '(^.)(.*)', (^.) matches the first character and (.*) matches the remaining characters.

myStrings
[[1]]
[1] "hello stackoverflow" "h"                   "ello stackoverflow" 

[[2]]
[1] "right back" "r"          "ight back" 

[[3]]
[1] "at yah" "a"      "t yah" 

Now, we can use the trusty sapply + [ method to pull out the desired substrings.

myFirstStrings <- sapply(myStrings, "[", 2)
myFirstStrings
[1] "h" "r" "a"
mySecondStrings <- sapply(myStrings, "[", 3)
mySecondStrings
[1] "ello stackoverflow" "ight back"          "t yah"

Simplest way to throw an Exception in C++:

#include <iostream>
using namespace std;
void purturb(){
    throw "Cannot purturb at this time.";
}
int main() {
    try{
        purturb();
    }
    catch(const char* msg){
        cout << "We caught a message: " << msg << endl;
    }
    cout << "done";
    return 0;
}

This prints:

We caught a message: Cannot purturb at this time.
done

If you catch the thrown exception, the exception is contained and the program will ontinue. If you do not catch the exception, then the program exists and prints:

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.

I did this in my project and it works like a charm

Date now = new Date();
System.out.println(now);
TimeZone.setDefault(TimeZone.getTimeZone("UTC")); // The magic is here
System.out.println(now);

I would just like to say that it REALLY isn't that difficult to get an xrange object with slice and indexing functionality. I have written some code that works pretty dang well and is just as fast as xrange for when it counts (iterations).

from __future__ import division

def read_xrange(xrange_object):
    # returns the xrange object's start, stop, and step
    start = xrange_object[0]
    if len(xrange_object) > 1:
       step = xrange_object[1] - xrange_object[0]
    else:
        step = 1
    stop = xrange_object[-1] + step
    return start, stop, step

class Xrange(object):
    ''' creates an xrange-like object that supports slicing and indexing.
    ex: a = Xrange(20)
    a.index(10)
    will work

    Also a[:5]
    will return another Xrange object with the specified attributes

    Also allows for the conversion from an existing xrange object
    '''
    def __init__(self, *inputs):
        # allow inputs of xrange objects
        if len(inputs) == 1:
            test, = inputs
            if type(test) == xrange:
                self.xrange = test
                self.start, self.stop, self.step = read_xrange(test)
                return

        # or create one from start, stop, step
        self.start, self.step = 0, None
        if len(inputs) == 1:
            self.stop, = inputs
        elif len(inputs) == 2:
            self.start, self.stop = inputs
        elif len(inputs) == 3:
            self.start, self.stop, self.step = inputs
        else:
            raise ValueError(inputs)

        self.xrange = xrange(self.start, self.stop, self.step)

    def __iter__(self):
        return iter(self.xrange)

    def __getitem__(self, item):
        if type(item) is int:
            if item < 0:
                item += len(self)

            return self.xrange[item]

            # get the indexes, and then convert to the number
            start, stop, step = item.start, item.stop, item.step
            start = start if start != None else 0 # convert start = None to start = 0
            if start < 0:
                start += start
            start = self[start]
            if start < 0: raise IndexError(item)
            step = (self.step if self.step != None else 1) * (step if step != None else 1)
            stop = stop if stop is not None else self.xrange[-1]
            if stop < 0:
                stop += stop

            stop = self[stop]
            stop = stop

            if stop > self.stop:
                raise IndexError
            if start < self.start:
                raise IndexError
            return Xrange(start, stop, step)

    def index(self, value):
        error = ValueError('object.index({0}): {0} not in object'.format(value))
        index = (value - self.start)/self.step
        if index % 1 != 0:
            raise error
        index = int(index)


        try:
            self.xrange[index]
        except (IndexError, TypeError):
            raise error
        return index

    def __len__(self):
        return len(self.xrange)

Honestly, I think the whole issue is kind of silly and xrange should do all of this anyway...

With SpringBoot 2 Spring Security, The code below perfectly resolved Cors issues

@Bean
public CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Collections.singletonList("*")); // <-- you may change "*"
    configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "POST", "PUT", "DELETE", "PATCH"));
    configuration.setAllowCredentials(true);
    configuration.setAllowedHeaders(Arrays.asList(
            "Accept", "Origin", "Content-Type", "Depth", "User-Agent", "If-Modified-Since,",
            "Cache-Control", "Authorization", "X-Req", "X-File-Size", "X-Requested-With", "X-File-Name"));
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

@Bean
public FilterRegistrationBean<CorsFilter> corsFilterRegistrationBean() {
    FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<>(new CorsFilter(corsConfigurationSource()));
    bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
    return bean;
}

Then for the WebSecurity Configuration, I added this

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.headers().frameOptions().disable()
            .and()
            .authorizeRequests()
            .antMatchers("/oauth/tokeen").permitAll()
            .antMatchers(HttpMethod.GET, "/").permitAll()
            .antMatchers(HttpMethod.POST, "/").permitAll()
            .antMatchers(HttpMethod.PUT, "/").permitAll()
            .antMatchers(HttpMethod.DELETE, "/**").permitAll()
            .antMatchers(HttpMethod.OPTIONS, "*").permitAll()
            .anyRequest().authenticated()
            .and().cors().configurationSource(corsConfigurationSource());
}

If you are using webpack. This imports files automatically and exports as api namespace.

So no need to update on every file addition.

import camelCase from "lodash-es";
const requireModule = require.context("./", false, /\.js$/); // 
const api = {};

requireModule.keys().forEach(fileName => {
  if (fileName === "./index.js") return;
  const moduleName = camelCase(fileName.replace(/(\.\/|\.js)/g, ""));
  api[moduleName] = {
    ...requireModule(fileName).default
  };
});

export default api;

For Typescript users;

import { camelCase } from "lodash-es"
const requireModule = require.context("./folderName", false, /\.ts$/)

interface LooseObject {
  [key: string]: any
}

const api: LooseObject = {}

requireModule.keys().forEach(fileName => {
  if (fileName === "./index.ts") return
  const moduleName = camelCase(fileName.replace(/(\.\/|\.ts)/g, ""))
  api[moduleName] = {
    ...requireModule(fileName).default,
  }
})

export default api

document.getElementById("email").validity.valid

seems to be true when field is either empty or valid. This also has some other interesting flags:

Tested in Chrome.

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

What you are asking for is a specialized form of compression. xdelta3 was designed for this particular kind of compression, and there's a python binding for it, but you could probably get away with using zlib directly. You'd want to use zlib.compressobj and zlib.decompressobj with the zdict parameter set to your "base word", e.g. afrykanerskojezyczny.

Caveats are zdict is only supported in python 3.3 and higher, and it's easiest to code if you have the same "base word" for all your diffs, which may or may not be what you want.

I tried to do the same as you, but apparently the backgroundImage doesn't work with encoded data. As an alternative, I suggest to use CSS classes and the change between those classes.

If you are generating the data "on the fly" you can load the CSS files dynamically.

CSS:

.backgroundA {

</div>
<input type="button" id="btn" />

Javascript:

function change() {
    if (document.getElementById("test").className =="backgroundA") {
        document.getElementById("test").className="backgroundB";
        document.getElementById("test2").className="backgroundA";
    } else {
        document.getElementById("test").className="backgroundA";
        document.getElementById("test2").className="backgroundB";
    }

I fiddled it here, press the button and it will switch the divs' backgrounds: http://jsfiddle.net/egorbatik/fFQC6/

Look at this example:

public void RunWorker()
{
    Thread newThread = new Thread(WorkerMethod);
    newThread.Start(new Parameter());
}

public void WorkerMethod(object parameterObj)
{
    var parameter = (Parameter)parameterObj;
    // do your job!
}

You are first creating a thread by passing delegate to worker method and then starts it with a Thread.Start method which takes your object as parameter.

So in your case you should use it like this:

    Thread thread = new Thread(download);
    thread.Start(filename);

But your 'download' method still needs to take object, not string as a parameter. You can cast it to string in your method body.

You can use this to copy directory overwriting existing files:

import shutil
shutil.copytree("src", "dst", dirs_exist_ok=True)

dirs_exist_ok argument was added in Python 3.8.

See docs: https://docs.python.org/3/library/shutil.html#shutil.copytree

This is really a tricky thing to have a sticky header on your table. I had same requirement but with asp:GridView and then I found it really thought to have sticky header on gridview. There are many solutions available and it took me 3 days trying all the solution but none of them could satisfy.

The main issue that I faced with most of these solutions was the alignment problem. When you try to make the header floating, somehow the alignment of header cells and body cells get off track.

With some solutions, I also got issue of getting header overlapped to first few rows of body, which cause body rows getting hidden behind the floating header.

So now I had to implement my own logic to achieve this, though I also not consider this as perfect solution but this could also be helpful for someone,

Below is the sample table.

<div class="table-holder">
        <table id="MyTable" cellpadding="4" cellspacing="0" border="1px" class="customerTable">
            <thead>
                <tr><th>ID</th><th>First Name</th><th>Last Name</th><th>DOB</th><th>Place</th></tr>
            </thead>
            <tbody>
                <tr><td>1</td><td>Customer1</td><td>LastName</td><td>1-1-1</td><td>SUN</td></tr>
                <tr><td>2</td><td>Customer2</td><td>LastName</td><td>2-2-2</td><td>Earth</td></tr>
                <tr><td>3</td><td>Customer3</td><td>LastName</td><td>3-3-3</td><td>Mars</td></tr>
                <tr><td>4</td><td>Customer4</td><td>LastName</td><td>4-4-4</td><td>Venus</td></tr>
                <tr><td>5</td><td>Customer5</td><td>LastName</td><td>5-5-5</td><td>Saturn</td></tr>
                <tr><td>6</td><td>Customer6</td><td>LastName</td><td>6-6-6</td><td>Jupitor</td></tr>
                <tr><td>7</td><td>Customer7</td><td>LastName</td><td>7-7-7</td><td>Mercury</td></tr>
                <tr><td>8</td><td>Customer8</td><td>LastName</td><td>8-8-8</td><td>Moon</td></tr>
                <tr><td>9</td><td>Customer9</td><td>LastName</td><td>9-9-9</td><td>Uranus</td></tr>
                <tr><td>10</td><td>Customer10</td><td>LastName</td><td>10-10-10</td><td>Neptune</td></tr>
            </tbody>
        </table>
    </div>

Note: The table is wrapped into a DIV with class attribute equal to 'table-holder'.

Below is the JQuery script that I added in my html page header.

<script src="../Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="../Scripts/jquery-ui.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        //create var for table holder
        var originalTableHolder = $(".table-holder");
        // set the table holder's with
        originalTableHolder.width($('table', originalTableHolder).width() + 17);
        // Create a clone of table holder DIV
        var clonedtableHolder = originalTableHolder.clone();

        // Calculate height of all header rows.
        var headerHeight = 0;
        $('thead', originalTableHolder).each(function (index, element) {
            headerHeight = headerHeight + $(element).height();
        });

        // Set the position of cloned table so that cloned table overlapped the original
        clonedtableHolder.css('position', 'relative');
        clonedtableHolder.css('top', headerHeight + 'px');

        // Set the height of cloned header equal to header height only so that body is not visible of cloned header
        clonedtableHolder.height(headerHeight);
        clonedtableHolder.css('overflow', 'hidden');

        // reset the ID attribute of each element in cloned table
        $('*', clonedtableHolder).each(function (index, element) {
            if ($(element).attr('id')) {
                $(element).attr('id', $(element).attr('id') + '_Cloned');
            }
        });

        originalTableHolder.css('border-bottom', '1px solid #aaa');

        // Place the cloned table holder before original one
        originalTableHolder.before(clonedtableHolder);
    });
</script>

and at last below is the CSS class for bit of coloring purpose.

.table-holder
{
    height:200px;
    overflow:auto;
    border-width:0px;    
}

.customerTable thead
{
    background: #4b6c9e;        
    color:White;
}

So the whole idea of this logic is to place the table into a table holder div and create clone of that holder at client side when page loaded. Now hide the body of table inside clone holder and position the remaining header part over to original header.

Same solution also works for asp:gridview, you need to add two more steps to achieve this in gridview,

1. In OnPrerender event of gridview object in your web page, set the table section of header row equal to TableHeader.

   if (this.HeaderRow != null)
   {
       this.HeaderRow.TableSection = TableRowSection.TableHeader;
   }
   

2. And wrap your grid into <div class="table-holder"></div>.

Note: if your header has clickable controls then you may need to add some more jQuery script to pass the events raised in cloned header to original header. This code is already available in jQuery sticky-header plugin create by jmosbech

Functions

<?php

/**
 * Is Array?
 * @param mixed $x
 * @return bool
 */
function isArray($x) : bool {
  return !isAssociative($x);
}

/**
 * Is Associative Array?
 * @param mixed $x
 * @return bool
 */
function isAssociative($x) : bool {
  if (!is_array($array)) {
    return false;
  }
  $i = count($array);
  while ($i > 0) {
    if (!isset($array[--$i])) {
      return true;
    }
  }
  return false;
}

Example

<?php

$arr = [ 'foo', 'bar' ];
$obj = [ 'foo' => 'bar' ];

var_dump(isAssociative($arr));
# bool(false)

var_dump(isAssociative($obj));
# bool(true)

var_dump(isArray($obj));
# bool(false)

var_dump(isArray($arr));
# bool(true)

Here is a working example in both Javascript and jQuery:

http://jsfiddle.net/GuLYN/312/

//In jQuery
$("#calculate").click(function() {
    var num = parseFloat($("#textbox").val());
    var new_num = $("#textbox").val(num.toFixed(2));
});


// In javascript
document.getElementById('calculate').onclick = function() {
    var num = parseFloat(document.getElementById('textbox').value);
    var new_num = num.toFixed(2);
    document.getElementById('textbox').value = new_num;
};
?

How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?

1. You can undo changes to tracked files with:

   git reset HEAD --hard
   

2. You can remove untracked files with:

   git clean -f
   

3. You can remove untracked files and directories with:

   git clean -fd
   

   but you can't undo change to untracked files.

4. You can remove ignored and untracked files and directories

   git clean -fdx
   

   but you can't undo change to ignored files.

You can also set clean.requireForce to false:

git config --global --add clean.requireForce false

to avoid using -f (--force) when you use git clean.

As mentioned you can use:

overflow: scroll;

If you only want the scroll bar to appear when necessary, you can use the "auto" option:

overflow: auto;

I don't think you should be using the "float" property with "overflow", but I'd have to try out your example first.

/* Most Accurate Setting if you only want
   to do this with CSS Pseudo Element */
p:before { 
   content: "\00a0";
   padding-right: 5px; /* If you need more space b/w contents */
}

I would also suggest extending TextView and other controls, but it would be better I consider to set up font in constructs.

public FontTextView(Context context) {
    super(context);
    init();
}

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

public FontTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
}

protected void init() {
    setTypeface(Typeface.createFromAsset(getContext().getAssets(), AppConst.FONT));
}

New since 1.8 is a List.sort() method instead of using the Collection.sort() so you directly call mylistcontainer.sort()

Here is a code snippet which demonstrates the List.sort() feature:

List<Fruit> fruits = new ArrayList<Fruit>();
fruits.add(new Fruit("Kiwi","green",40));
fruits.add(new Fruit("Banana","yellow",100));
fruits.add(new Fruit("Apple","mixed green,red",120));
fruits.add(new Fruit("Cherry","red",10));

// a) using an existing compareto() method
fruits.sort((Fruit f1,Fruit f2) -> f1.getFruitName().compareTo(f2.getFruitName()));
System.out.println("Using String.compareTo(): " + fruits);
//Using String.compareTo(): [Apple is: mixed green,red, Banana is: yellow, Cherry is: red, Kiwi is: green]

// b) Using a comparable class
fruits.sort((Fruit f1,Fruit f2) -> f1.compareTo(f2));  
System.out.println("Using a Comparable Fruit class (sort by color): " + fruits);
// Using a Comparable Fruit class (sort by color): [Kiwi is green, Apple is: mixed green,red, Cherry is: red, Banana is: yellow]

The Fruit class is:

public class Fruit implements Comparable<Fruit>
{
    private String name;
    private String color;
    private int quantity;

    public Fruit(String name,String color,int quantity)
    { this.name = name; this.color = color; this.quantity = quantity; }

    public String getFruitName() { return name; }        
    public String getColor() { return color; }  
    public int getQuantity() { return quantity; }

    @Override public final int compareTo(Fruit f) // sorting the color
    {
        return this.color.compareTo(f.color);
    }     
    @Override public String toString()
    {   
        return (name + " is: " + color);
    }
} // end of Fruit class   

ASCII and Unicode are two character encodings. Basically, they are standards on how to represent difference characters in binary so that they can be written, stored, transmitted, and read in digital media. The main difference between the two is in the way they encode the character and the number of bits that they use for each. ASCII originally used seven bits to encode each character. This was later increased to eight with Extended ASCII to address the apparent inadequacy of the original. In contrast, Unicode uses a variable bit encoding program where you can choose between 32, 16, and 8-bit encodings. Using more bits lets you use more characters at the expense of larger files while fewer bits give you a limited choice but you save a lot of space. Using fewer bits (i.e. UTF-8 or ASCII) would probably be best if you are encoding a large document in English.

One of the main reasons why Unicode was the problem arose from the many non-standard extended ASCII programs. Unless you are using the prevalent page, which is used by Microsoft and most other software companies, then you are likely to encounter problems with your characters appearing as boxes. Unicode virtually eliminates this problem as all the character code points were standardized.

Another major advantage of Unicode is that at its maximum it can accommodate a huge number of characters. Because of this, Unicode currently contains most written languages and still has room for even more. This includes typical left-to-right scripts like English and even right-to-left scripts like Arabic. Chinese, Japanese, and the many other variants are also represented within Unicode. So Unicode won’t be replaced anytime soon.

In order to maintain compatibility with the older ASCII, which was already in widespread use at the time, Unicode was designed in such a way that the first eight bits matched that of the most popular ASCII page. So if you open an ASCII encoded file with Unicode, you still get the correct characters encoded in the file. This facilitated the adoption of Unicode as it lessened the impact of adopting a new encoding standard for those who were already using ASCII.

Summary:

1.ASCII uses an 8-bit encoding while Unicode uses a variable bit encoding.
2.Unicode is standardized while ASCII isn’t.
3.Unicode represents most written languages in the world while ASCII does not.
4.ASCII has its equivalent within Unicode.

The standard function atoi() will likely do what you want.

A simple example using "atoi":

#include <unistd.h>

int main(int argc, char *argv[])
{
    int useconds = atoi(argv[1]); 
    usleep(useconds);
}

I just ran into a similar situation. I didn't want to use JQuery, and wanted to do this using pure Javascript.

And what I did was, used the following condition, and it worked for me.

var obj = {};
if(JSON.stringify(obj) === '{}') { //This will check if the object is empty
   //Code here..
}

For not equal to, use this : JSON.stringify(obj) !== '{}'

Check out this JSFiddle

It would be easier to use relative layouts, but for linear layouts I usually center by making sure the width matches parent :

    android:layout_width="match_parent"

and then just give margins to right and left accordingly.

    android:layout_marginLeft="20dp"
    android:layout_marginRight="20dp"

You may find that gnuplot's for loops are useful in this case, if you adjust your filenames or graph titles appropriately.

e.g.

filenames = "first second third fourth fifth"
plot for [file in filenames] file."dat" using 1:2 with lines

and

filename(n) = sprintf("file_%d", n)
plot for [i=1:10] filename(i) using 1:2 with lines

Use FileInfo.Exists Property:

DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles("*.xml");
if (TXTFiles.Length == 0)
{
    log.Info("no files present")
}
foreach (var fi in TXTFiles)
    log.Info(fi.Exists);

or File.Exists Method:

string curFile = @"c:\temp\test.txt";
Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");

The easiest way I've seen is to use Google Fonts.

Go to Google Fonts and choose a font, then Google will give you a link to put in your HTML.

Then add this to your custom.css:

h1, h2, h3, h4, h5, h6 {
    font-family: 'Your Font' !important;
}
p, div {
    font-family: 'Your Font' !important;
}

or

body {
   font-family: 'Your Font' !important;
}

I create a file dif.go that contains your code:

package dif

import (
    "time"
)

var StartTime = time.Now()

Outside the folder I create my main.go, it is ok!

package main

import (
    dif "./dif"
    "fmt"
)

func main() {
    fmt.Println(dif.StartTime)
}

Outputs:

2016-01-27 21:56:47.729019925 +0800 CST

Files directory structure:

folder
  main.go
  dif
    dif.go

It works!

To get min/max value in array, you can use:

var _array = [1,3,2];
Math.max.apply(Math,_array); // 3
Math.min.apply(Math,_array); // 1

In bash and vim I use Lucida Typewriter, but in Kate, Scintilla, Eclipse, and Netbeans I (currently) use Lucida Casual, i.e., a proportional font. Ten years ago I started using proportional fonts in Visual Studio (MS Comic Sans) and it works very well for me. Colored syntax highlighting in said IDEs provides excellent readability and for text-heavy languages like HTML and LaTeX a proportional font is a natural choice.

If you get your adb from Android Studio (which most will nowadays since Android is deprecated on Eclipse), your adb program will most likely be located here:

%USERPROFILE%\AppData\Local\Android\sdk\platform-tools

Where %USERPROFILE% represents something like C:\Users\yourName.

If you go into your computer's environmental variables and add %USERPROFILE%\AppData\Local\Android\sdk\platform-tools to the PATH (just copy-paste that line, even with the % --- it will work fine, at least on Windows, you don't need to hardcode your username) then it should work now. Open a new command prompt and type adb to check.

See this article from JoelOnSoftware for why you don't want to use strcat.

Look at fread for an alternative. Use it with 1 for the size when you're reading bytes or characters.

user_input = gets.chomp
user_input.downcase!

if user_input.include?('substring')
  # Do something
end

This will help you check if the string contains substring or not

puts "Enter a string"
user_input = gets.chomp  # Ex: Tommy
user_input.downcase!    #  tommy


if user_input.include?('s')
    puts "Found"
else
    puts "Not found"
end

In Kotlin you can create extension property:

inline var TextView.underline: Boolean
    set(visible) {
        paintFlags = if (visible) paintFlags or Paint.UNDERLINE_TEXT_FLAG
        else paintFlags and Paint.UNDERLINE_TEXT_FLAG.inv()
    }
    get() = paintFlags and Paint.UNDERLINE_TEXT_FLAG == Paint.UNDERLINE_TEXT_FLAG

And use:

textView.underline = true

Don't make data frames. Keep the list, name its elements but do not attach it.

The biggest reason for this is that if you make variables on the go, almost always you will later on have to iterate through each one of them to perform something useful. There you will again be forced to iterate through each one of the names that you have created on the fly.

It is far easier to name the elements of the list and iterate through the names.

As far as attach is concerned, its really bad programming practice in R and can lead to a lot of trouble if you are not careful.

Another option:

$(el).trigger({type: 'keypress', which: 13, keyCode: 13});

I had this problem and I realized that I was assuming that Geocoding came with the JS maps API. However, it is a separate API which I hadn't enabled in the cloud console. Enabling it fixed it right away.

Like Obediah Stane said, it's necessary to create your own format method. But I would change a few things:

• Create a subclass directly derived from Formatter, not from SimpleFormatter. The SimpleFormatter has nothing to add anymore.

• Be careful with creating a new Date object! You should make sure to represent the date of the LogRecord. When creating a new Date with the default constructor, it will represent the date and time the Formatter processes the LogRecord, not the date that the LogRecord was created.

The following class can be used as formatter in a Handler, which in turn can be added to the Logger. Note that it ignores all class and method information available in the LogRecord.

import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.Date;
import java.util.logging.Formatter;
import java.util.logging.LogRecord;

public final class LogFormatter extends Formatter {

    private static final String LINE_SEPARATOR = System.getProperty("line.separator");

    @Override
    public String format(LogRecord record) {
        StringBuilder sb = new StringBuilder();

        sb.append(new Date(record.getMillis()))
            .append(" ")
            .append(record.getLevel().getLocalizedName())
            .append(": ")
            .append(formatMessage(record))
            .append(LINE_SEPARATOR);

        if (record.getThrown() != null) {
            try {
                StringWriter sw = new StringWriter();
                PrintWriter pw = new PrintWriter(sw);
                record.getThrown().printStackTrace(pw);
                pw.close();
                sb.append(sw.toString());
            } catch (Exception ex) {
                // ignore
            }
        }

        return sb.toString();
    }
}

Added here for future reference (for users who might fall into the same case): This error happens when working on Windows (which introduces extra characters because of different line separator than Linux system) and trying to run this script (with extra characters inserted) in Linux. The error message is misleading.

In Windows, the line separator is CRLF (\r\n) whereas in linux it is LF (\n). This can be usually be chosen in text editor.

In my case, this happened due to working on Windows and uploading to Unix server for execution.

We can set the width for ul tag then it will align center.

#header ul {
    display: block;
    margin: 0 auto;
    width: 420px;
    max-width: 100%;
}

You can also use,

parent.jQuery("#testdiv").attr("style", content from form);

Is that trying to execute C:\Documents with arguments of "and", "Settings/flow_model/flow.exe"?

Also, you might consider subprocess.call().

You can use a trick, by creating a <a>-element, then setting the string to the href of that <a>-element and then you have a Location object you can get the hostname from.

You could either add a method to the String prototype:

String.prototype.toLocation = function() {
    var a = document.createElement('a');
    a.href = this;
    return a;
};

and use it like this:
"http://www.abc.com/search".toLocation().hostname

or make it a function:

function toLocation(url) {
    var a = document.createElement('a');
    a.href = url;
    return a;
};

and use it like this:
toLocation("http://www.abc.com/search").hostname

both of these will output: "www.abc.com"

If you also need the protocol, you can do something like this:

var url = "http://www.abc.com/search".toLocation();
url.protocol + "//" + url.hostname

which will output: "http://www.abc.com"

void foo(vector<int> test)

vector would be passed by value in this.

You have more ways to pass vectors depending on the context:-

1) Pass by reference:- This will let function foo change your contents of the vector. More efficient than pass by value as copying of vector is avoided.

2) Pass by const-reference:- This is efficient as well as reliable when you don't want function to change the contents of the vector.

You should use a simple IF statement

List<String> data = GetData();

if (data.Count == 0)
    throw new Exception("Data Empty!");

PopulateGrid();
ShowGrid();

I implemented a hasOne relation in my parent class, defined both the foreign and local key, it returned an object but the columns of the child must be accessed as an array.
i.e. $parent->child['column']
Kind of confusing.

git pull is really just a shorthand for git pull <remote> <branchname>, in most cases it's equivalent to git pull origin master. You will need to add another remote and pull explicitly from it. This page describes it in detail:

http://help.github.com/forking/

Assuming that onMove is an event handler, it is likely that its context is something other than the instance of MyContainer, i.e. this points to something different.

You can manually bind the context of the function during the construction of the instance via Function.bind:

class MyContainer extends Component {
  constructor(props) {
    super(props);

    this.onMove = this.onMove.bind(this);

    this.test = "this is a test";
  }

  onMove() {
    console.log(this.test);
  }
}

Also, test !== testVariable.

You could use the old ways. And use a table. In the table you define 3 columns. You set the width of your whole table and define the width of every colum. that way you can horizantaly space 2 objects. You put object one inside cell1 (colum1, row1) and object2 in cell3 (colum 3, row 1) and you leave cell 2 empty. Given it has a width, you will see empty spaces. example

<table width="500">
    <tr>
        <td width="40%">
            Object 1
        </td>
        <td width="20%">

        </td>
        <td width="40%">
            Object 2
        </td>
    </tr>
</table>

Or you could go the better way with div's. Just put your objects inside divs. Add a middle div and put these 3 divs inside another div. At the css style to the upper div: overflow: auto and define a width. Add css style to the 3 divs to define their width and add float: left example

<div style="overflow: auto;width: 100%;">
    <div style="width:200px;float: left;">
        Object  1
    </div>
    <div style="width:200px;float: left;">

    </div>
    <div style="width:200px;float: left;">
        Object  2
    </div>
</div>

jquery provides val() function and not value(). You can check empty string using jquery

if($('#person_data[document_type]').val() != ''){}

There is a simpler way. If you set layout constraints as follows and your EditText is fixed sized, it will get centered in the constraint layout:

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"

The left/right pair centers the view horizontally and top/bottom pair centers it vertically. This is because when you set the left, right or top,bottom constraints bigger than the view it self, the view gets centered between the two constraints i.e the bias is set to 50%. You can also move view up/down or right/left by setting the bias your self. Play with it a bit and you will see how it affects the views position.

The easiest solution for the selected option in dropdown using PHP is following

<select class="form-control" name="currency_selling" required >
         <option value="">Select Currency</option>
         <option value="pkr" <?=$selected_currency == 'pkr' ? ' selected="selected"' : '';?> >PKR</option>
      <option value="dollar"  <?=$selected_currency == 'dollar' ? ' selected="selected"' : '';?> >USD</option>
      <option value="pounds"  <?=$selected_currency == 'pounds' ? ' selected="selected"' : '';?> >POUNDS</option>
      <option value="dirham"  <?=$selected_currency == 'dirham' ? ' selected="selected"' : '';?> >DRHM</option>
      </select>

refer johnml1135 answer, but not fully work.

after self investigate, work now:

as official say:

????

????????????????????? /sdcard/Download ???????? API ?????????????,?? API 22,?????:Settings > Device:Storage & USB > Internal Storage > Explore(?? SD ?)?

and use Drag and Drop actually worked, but use android self installed app Download, then you can NOT find the copied file, for not exist so called /sdcard/Download folder.

finally using other file manager app, like

ES File Explorer

then can see the really path is

/storage/emulated/0/Download/

which contains the copied files, like

/storage/emulated/0/Download/chenhongyu_lixiangsanxun.mp3

after drag and drop more mp3 files:

Take below reference to convert a JSON into POJO and vice-versa

Let's suppose your JSON schema looks like:

{
  "type":"object",
  "properties": {
    "dataOne": {
      "type": "string"
    },
    "dataTwo": {
      "type": "integer"
    },
    "dataThree": {
      "type": "boolean"
    }
  }
}

Then to covert into POJO, your need to decleare some classes as explained in below style:

==================================
package ;
public class DataOne
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class DataTwo
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class DataThree
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class Properties
{
    private DataOne dataOne;

    private DataTwo dataTwo;

    private DataThree dataThree;

    public void setDataOne(DataOne dataOne){
        this.dataOne = dataOne;
    }
    public DataOne getDataOne(){
        return this.dataOne;
    }
    public void setDataTwo(DataTwo dataTwo){
        this.dataTwo = dataTwo;
    }
    public DataTwo getDataTwo(){
        return this.dataTwo;
    }
    public void setDataThree(DataThree dataThree){
        this.dataThree = dataThree;
    }
    public DataThree getDataThree(){
        return this.dataThree;
    }
}

==================================
package ;
public class Root
{
    private String type;

    private Properties properties;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
    public void setProperties(Properties properties){
        this.properties = properties;
    }
    public Properties getProperties(){
        return this.properties;
    }
}

Yet another solution:

I got inside objects.mk file

################################################################################
# Automatically-generated file. Do not edit!
################################################################################

USER_OBJS := /home/../mylib.so

LIBS := -lstdc++fs -lGL -lGLU -lGLEW -lglut -lm -lmylib

then didn't read first line. Then altered next line. It was another projects' folder because I copied this using "copy/clone project" feature and this was causing the error for me. I changed myLib.so into /proper_address/reallyMyLib.so and it worked.

Warning: It may harm some unknown places! Backup whole project before doing this. Because it says "do not edit".

$('#someButton').click(function() {
    window.location.href = '/some/new/page';
    return false;
});

// set your date here
$mydate = "2009-01-01";

/* strtotime accepts two parameters.
The first parameter tells what it should compute.
The second parameter defines what source date it should use. */
$lastyear = strtotime("-1 year", strtotime($mydate));

// format and display the computed date
echo date("Y-m-d", $lastyear);

I saw a presentation on mongodb yesterday. I can definitely say that setup was "simple", as simple as unpacking it and firing it up. Done.

I believe that both mongodb and cassandra will run on virtually any regular linux hardware so you should not find to much barrier in that area.

I think in this case, at the end of the day, it will come down to which do you personally feel more comfortable with and which has a toolset that you prefer. As far as the presentation on mongodb, the presenter indicated that the toolset for mongodb was pretty light and that there werent many (they said any really) tools similar to whats available for MySQL. This was of course their experience so YMMV. One thing that I did like about mongodb was that there seemed to be lots of language support for it (Python, and .NET being the two that I primarily use).

The list of sites using mongodb is pretty impressive, and I know that twitter just switched to using cassandra.

Based on the other answers, here is a first draft for usage with knockout:

Usage

      <div data-bind="editableSelect: {options: optionsObservable, value: nameObservable}"></div>

Knockout data binding

composition.addBindingHandler('editableSelect',
  {
    init: function(hostElement, valueAccessor) {

      var optionsObservable = getOptionsObservable();
      var valueObservable = getValueObservable();

      var $editableSelect = $(hostElement);
      $editableSelect.addClass('select-editable');

      var editableSelect = $editableSelect[0];

      var viewModel = new editableSelectViewModel(optionsObservable, valueObservable);
      ko.applyBindingsToNode(editableSelect, { compose: viewModel });

      //tell knockout to not apply bindings twice
      return { controlsDescendantBindings: true };

      function getOptionsObservable() {
        var accessor = valueAccessor();
        return getAttribute(accessor, 'options');
      }

      function getValueObservable() {
        var accessor = valueAccessor();
        return getAttribute(accessor, 'value');
      }
    }
  });

View

<select
  data-bind="options: options, event:{ focus: resetComboBoxValue, change: setTextFieldValue} "
  id="comboBox"
  ></select>
<input
  data-bind="value: value, , event:{ focus: textFieldGotFocus, focusout: textFieldLostFocus}"
  id="textField"
  type="text"/>

ViewModel

define([
  'lodash',
  'services/errorHandler'
], function(
  _,
  errorhandler
) {

  var viewModel = function(optionsObservable, valueObservable) {

    var self = this;
    self.options = optionsObservable();
    self.value = valueObservable;
    self.resetComboBoxValue = resetComboBoxValue;
    self.setTextFieldValue = setTextFieldValue;
    self.textFieldGotFocus = textFieldGotFocus;
    self.textFieldLostFocus = textFieldLostFocus;

    function resetComboBoxValue() {
      $('#comboBox').val(null);
    }

    function setTextFieldValue() {
      var selection = $('#comboBox').val();
      self.value(selection);
    }

    function textFieldGotFocus() {
      $('#comboBox').addClass('select-editable-input-focus');

    }

    function textFieldLostFocus() {
      $('#comboBox').removeClass('select-editable-input-focus');
    }

  };
  errorhandler.includeIn(viewModel);

  return viewModel;
});

Before you run make oldconfig, you need to copy a kernel configuration file from an older kernel into the root directory of the new kernel.

You can find a copy of the old kernel configuration file on a running system at /boot/config-3.11.0. Alternatively, kernel source code has configs in linux-3.11.0/arch/x86/configs/{i386_defconfig / x86_64_defconfig}

If your kernel source is located at /usr/src/linux:

cd /usr/src/linux
cp /boot/config-3.9.6-gentoo .config
make oldconfig

After looking at this and trying it out I found it actually didn't allow more than one instance of jquery to run at a time. After searching around I found that this did just the trick and was a whole lot less code.

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
    <script>var $j = jQuery.noConflict(true);</script>
    <script>
      $(document).ready(function(){
       console.log($().jquery); // This prints v1.4.2
       console.log($j().jquery); // This prints v1.9.1
      });
   </script>

So then adding the "j" after the "$" was all I needed to do.

$j(function () {
        $j('.button-pro').on('click', function () {
            var el = $('#cnt' + this.id.replace('btn', ''));
            $j('#contentnew > div').not(el).animate({
                height: "toggle",
                opacity: "toggle"
            }, 100).hide();
            el.toggle();
        });
    });

There is a bug filed for Eclipse:

You could try restarting Eclipse, it helped the original poster of the issue there.

Likely a problem with the path that you specified in Javadoc Location. It is pretty finicky. Make sure that it points at the root of where the javadoc starts. It could be a few directories down in the zip you've downloaded.

explained for g++ here, though it is part of C99 so should work for everyone

Maybe this is not the answer you needed, but I encountered similar problem, so I decided to put it here.

I needed to convert 500 xml files to UTF8 via Notepad++. Why Notepad++? When I used the option "Encode in UTF8" (many other converters use the same logic) it messed up all special characters, so I had to use "Convert to UTF8" explicitly.

Here some simple steps to convert multiple files via Notepad++ without messing up with special characters (for ex. diacritical marks).

1. Run Notepad++ and then open menu Plugins->Plugin Manager->Show Plugin Manager
2. Install Python Script. When plugin is installed, restart the application.
3. Choose menu Plugins->Python Script->New script.
4. Choose its name, and then past the following code:

convertToUTF8.py

import os
import sys
from Npp import notepad # import it first!

filePathSrc="C:\\Users\\" # Path to the folder with files to convert
for root, dirs, files in os.walk(filePathSrc):
    for fn in files: 
        if fn[-4:] == '.xml': # Specify type of the files
            notepad.open(root + "\\" + fn)      
            notepad.runMenuCommand("Encoding", "Convert to UTF-8")
            # notepad.save()
            # if you try to save/replace the file, an annoying confirmation window would popup.
            notepad.saveAs("{}{}".format(fn[:-4], '_utf8.xml')) 
            notepad.close()

After all, run the script

If you set excluded architectures for the simulator to arm64 it will compile.

I've a problem with H2 version 1.4.190 remote connection to inMemory (as well as in file) with Connection is broken: "unexpected status 16843008" until do not downgrade to 1.3.176. See Grails accessing H2 TCP server hangs

You can use the below extension for your convenience.

Usage inside a ViewController:

showInputDialog(title: "Add number",
                subtitle: "Please enter the new number below.",
                actionTitle: "Add",
                cancelTitle: "Cancel",
                inputPlaceholder: "New number",
                inputKeyboardType: .numberPad)
{ (input:String?) in
    print("The new number is \(input ?? "")")
}

The extension code:

extension UIViewController {
    func showInputDialog(title:String? = nil,
                         subtitle:String? = nil,
                         actionTitle:String? = "Add",
                         cancelTitle:String? = "Cancel",
                         inputPlaceholder:String? = nil,
                         inputKeyboardType:UIKeyboardType = UIKeyboardType.default,
                         cancelHandler: ((UIAlertAction) -> Swift.Void)? = nil,
                         actionHandler: ((_ text: String?) -> Void)? = nil) {

        let alert = UIAlertController(title: title, message: subtitle, preferredStyle: .alert)
        alert.addTextField { (textField:UITextField) in
            textField.placeholder = inputPlaceholder
            textField.keyboardType = inputKeyboardType
        }
        alert.addAction(UIAlertAction(title: actionTitle, style: .default, handler: { (action:UIAlertAction) in
            guard let textField =  alert.textFields?.first else {
                actionHandler?(nil)
                return
            }
            actionHandler?(textField.text)
        }))
        alert.addAction(UIAlertAction(title: cancelTitle, style: .cancel, handler: cancelHandler))

        self.present(alert, animated: true, completion: nil)
    }
}

By convention, .h files are included by other files, and never compiled directly by themselves. .cpp files are - again, by convention - the roots of the compilation process; they include .h files directly or indirectly, but generally not .cpp files.

For Tomcat 7 to increase memory :

Identify your service name, you will find it in the service properties, under the "Path to executable" at the end of the line

For me it is //RS//Tomcat70 so the name is Tomcat70

Then write as administrator :

tomcat7.exe //US//Tomcat70 --JvmOptions=-Xmx1024M

Something else you can use is isnull:

isnull( SUBSTRING(PostCode, 1 , CHARINDEX(' ', PostCode ) -1), PostCode)

The main difference is when compiled in debug mode, pdb files are also created which allow debugging (so you can step through the code when its running). This however means that the code isn't optimized as much.

I have looked at the above answers and have mixed together this version which works for me:

function getFilesFromPath(path, extension) {
    let files = fs.readdirSync( path );
    return files.filter( file => file.match(new RegExp(`.*\.(${extension})`, 'ig')));
}

console.log(getFilesFromPath("./testdata", ".txt"));

This test will return an array of filenames from the files found in the folder at the path ./testdata. Working on node version 8.11.3.

It's an old question, but I found this can be done easily with Spacy. Once the document is read, a simple api similarity can be used to find the cosine similarity between the document vectors.

import spacy
nlp = spacy.load('en')
doc1 = nlp(u'Hello hi there!')
doc2 = nlp(u'Hello hi there!')
doc3 = nlp(u'Hey whatsup?')

print doc1.similarity(doc2) # 0.999999954642
print doc2.similarity(doc3) # 0.699032527716
print doc1.similarity(doc3) # 0.699032527716

As mentioned by others there's no cross platform way to do this, but on Windows you can do it like this:

The Code below checks if the key 'A' is down.

if(GetKeyState('A') & 0x8000/*Check if high-order bit is set (1 << 15)*/)
{
    // Do stuff
}

In case of shift or similar you will need to pass one of these: https://msdn.microsoft.com/de-de/library/windows/desktop/dd375731(v=vs.85).aspx

if(GetKeyState(VK_SHIFT) & 0x8000)
{
    // Shift down
}

The low-order bit indicates if key is toggled.

SHORT keyState = GetKeyState(VK_CAPITAL/*(caps lock)*/);
bool isToggled = keyState & 1;
bool isDown = keyState & 0x8000;

Oh and also don't forget to

#include <Windows.h>

You don't add or link directly against a DLL, you link against the LIB produced by the DLL.

A LIB provides symbols and other necessary data to either include a library in your code (static linking) or refer to the DLL (dynamic linking).

To link against a LIB, you need to add it to the project Properties -> Linker -> Input -> Additional Dependencies list. All LIB files here will be used in linking. You can also use a pragma like so:

#pragma comment(lib, "dll.lib")

With static linking, the code is included in your executable and there are no runtime dependencies. Dynamic linking requires a DLL with matching name and symbols be available within the search path (which is not just the path or system directory).

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

• $$ is the current script's pid
• $! is the pid of the last background process

Here's a sample transcript from a bash session (%1 refers to the ordinal number of background process as seen from jobs):

$ echo $$
3748

$ sleep 100 &
[1] 192

$ echo $!
192

$ kill %1

[1]+  Terminated              sleep 100

Because this captures all exceptions. It's unlikely that your program can recover from any of them.

You should handle only exceptions that you know how to recover from. If you don't anticipate a certain kind of exception, don't handle it, crash loudly (write details to the log), then diagnose logs and fix code.

Swallowing exceptions is bad, don't do this.

In your app's build.gradle add the following:

android {
    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
    }
}

Enforces Gradle to only compile the version number you state for all dependencies, no matter which version number the dependencies have stated.

I have a huge database with no (separate) index.

Any time I query by the primary key the results are, for all intensive purposes, instant.

Changing the web.config generally causes an application restart.

If you really need your application to edit its own settings, then you should consider a different approach such as databasing the settings or creating an xml file with the editable settings.

Here are available options if it helps anyone for on_delete

CASCADE, DO_NOTHING, PROTECT, SET, SET_DEFAULT, SET_NULL

You can fix your example with the iterator pattern by changing the parametrization of the class:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Iterator<Room> i = rooms.iterator(); i.hasNext(); ) {
  String item = i.next();
  System.out.println(item);
}

or much simpler way:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Room room : rooms) {
  System.out.println(room);
}

I believe in JBoss somewhere there was a line that read

return null; //Not really null

I always liked that line.

You can use this syntax if some grads are attached with your variables.

y=torch.Tensor.cpu(x).detach().numpy()[:,:,:,-1]

Here's an example of a function that accepts a callback

const sqk = (x: number, callback: ((_: number) => number)): number => {
  // callback will receive a number and expected to return a number
  return callback (x * x);
}

// here our callback will receive a number
sqk(5, function(x) {
  console.log(x); // 25
  return x;       // we must return a number here
});

If you don't care about the return values of callbacks (most people don't know how to utilize them in any effective way), you can use void

const sqk = (x: number, callback: ((_: number) => void)): void => {
  // callback will receive a number, we don't care what it returns
  callback (x * x);
}

// here our callback will receive a number
sqk(5, function(x) {
  console.log(x); // 25
  // void
});

Note, the signature I used for the callback parameter ...

const sqk = (x: number, callback: ((_: number) => number)): number

I would say this is a TypeScript deficiency because we are expected to provide a name for the callback parameters. In this case I used _ because it's not usable inside the sqk function.

However, if you do this

// danger!! don't do this
const sqk = (x: number, callback: ((number) => number)): number

It's valid TypeScript, but it will interpreted as ...

// watch out! typescript will think it means ...
const sqk = (x: number, callback: ((number: any) => number)): number

Ie, TypeScript will think the parameter name is number and the implied type is any. This is obviously not what we intended, but alas, that is how TypeScript works.

So don't forget to provide the parameter names when typing your function parameters... stupid as it might seem.
