Programs & Examples On #Zigbee

In my case I had a Kotlin class with some fields which were not open so the generated Java setters and getters would be final. Solved it by adding open keyword to each field.

Before:

open class User(
    var id: String = "",
    var email: String = ""
)

After:

open class User(
    open var id: String = "",
    open var email: String = ""
)

You can kill two birds with one regex stone:

>>> r = """
... \n\tName: John Smith
... \n\t  Home: Anytown USA
... \n\t    Phone: 555-555-555
... \n\t  Other Home: Somewhere Else
... \n\t Notes: Other data
... \n\tName: Jane Smith
... \n\t  Misc: Data with spaces
... """
>>> import re
>>> print re.findall(r'(\S[^:]+):\s*(.*\S)', r)
[('Name', 'John Smith'), ('Home', 'Anytown USA'), ('Phone', '555-555-555'), ('Other Home', 'Somewhere Else'), ('Notes', 'Other data'), ('Name', 'Jane Smith'), ('Misc', 'Data with spaces')]
>>> 

There are two parts in building barcode scanning feature, one capturing barcode image using camera and second extracting barcode value from the image.

Barcode image can be captured from your app using camera app and barcode value can be extracted using Firebase Machine Learning Kit barcode scanning API.

Here is an example app https://www.zoftino.com/android-barcode-scanning-example

Here lot of good answer but i think this will help someone

select id  from campaign where ( NOW() BETWEEN start_date AND end_date) 

If you want to do it in code, use the System.Web.HttpCookie.HttpOnly property.

This is directly from the MSDN docs:

// Create a new HttpCookie.
HttpCookie myHttpCookie = new HttpCookie("LastVisit", DateTime.Now.ToString());
// By default, the HttpOnly property is set to false 
// unless specified otherwise in configuration.
myHttpCookie.Name = "MyHttpCookie";
Response.AppendCookie(myHttpCookie);
// Show the name of the cookie.
Response.Write(myHttpCookie.Name);
// Create an HttpOnly cookie.
HttpCookie myHttpOnlyCookie = new HttpCookie("LastVisit", DateTime.Now.ToString());
// Setting the HttpOnly value to true, makes
// this cookie accessible only to ASP.NET.
myHttpOnlyCookie.HttpOnly = true;
myHttpOnlyCookie.Name = "MyHttpOnlyCookie";
Response.AppendCookie(myHttpOnlyCookie);
// Show the name of the HttpOnly cookie.
Response.Write(myHttpOnlyCookie.Name);

Doing it in code allows you to selectively choose which cookies are HttpOnly and which are not.

To those who use centos and have stumbled upon this post :

 $ yum install curl-devel

and when compiling your program example.cpp, link to the curl library:

 $ g++ example.cpp -lcurl -o example

"-o example" creates the executable example instead of the default a.out.

The next line runs example:

 $ ./example

You should implement a Custom List View, such that you define a Layout once and draw it for every row in the list view.

Don't forget to change the iDisplayLength as well:

$(document).ready(function() {
    $('#tbl_id').dataTable({
        "aLengthMenu": [[25, 50, 75, -1], [25, 50, 75, "All"]],
        "iDisplayLength": 25
    });
} );

I don't have much experience with this, but the following seems to work for what I'm doing:

dict(row)

This seems too simple (compared to the other answers here). What am I missing?

for my experience, Ellipsis works only if below two attributes are set.

android:ellipsize="end"
android:singleLine="true"

for the width of textview, wrap_content or match_parent should both be good.

As it is written in the documentation you have to change the cell type to a markdown.

Alternative:

library(stringr)
a = c("capitalise this", "and this")
a
[1] "capitalise this" "and this"       
str_to_title(a)
[1] "Capitalise This" "And This"   

Further to the answer from Diodeus above, you need the font-family: FontAwesome rule (assuming you have the @font-face rule for FontAwesome declared already in your CSS). Then it is a matter of knowing which CSS content value corresponds to which icon.

I have listed them all here: http://astronautweb.co/snippet/font-awesome/

Since it was a successful comment, I am adding it as an answer:
with files:

 find . | sed -e "s/[^-][^\/]*\//  |/g" -e "s/|\([^ ]\)/|-\1/" 

Go to the first line from which you would like to delete, and press the keys dG

I'm using a BindingSource with a SqlDataReader behind it and none of the above works for me.

Question for Microsoft: Why does this work:

  ? lst.SelectedValue

But this doesn't?

   ? lst.Items[80].Value

I find I have to go back to to the BindingSource object, cast it as a System.Data.Common.DbDataRecord, and then refer to its column name:

   ? ((System.Data.Common.DbDataRecord)_bsBlocks[80])["BlockKey"]

Now that's just ridiculous.

As the original question does not state which NuGet frontend should be used, I would like to mention that NuGet 3.5 adds support for updating to a specific version via the command line client (which works for downgrades, too):

NuGet.exe update Common.Logging -Version 1.2.0

Simply outputting something is PowerShell is a thing of beauty - and one its greatest strengths. For example, the common Hello, World! application is reduced to a single line:

"Hello, World!"

It creates a string object, assigns the aforementioned value, and being the last item on the command pipeline it calls the .toString() method and outputs the result to STDOUT (by default). A thing of beauty.

The other Write-* commands are specific to outputting the text to their associated streams, and have their place as such.

I have struggled with this problem for a while today. I read through the AngularJS documentation, this and other posts and a few of blogs they lead to. They all helped me grock the finer details, but in the end this just seems to be a confusing topic. Mainly because of the many syntactical nuances of ng-options.

In the end, for me, it came down to less is more.

Given a scope configured as follows:

        //Data used to populate the dropdown list
        $scope.list = [
           {"FirmnessID":1,"Description":"Soft","Value":1},         
           {"FirmnessID":2,"Description":"Medium-Soft","Value":2},
           {"FirmnessID":3,"Description":"Medium","Value":3}, 
           {"FirmnessID":4,"Description":"Firm","Value":4},     
           {"FirmnessID":5,"Description":"Very Firm","Value":5}];

        //A record or row of data that is to be save to our data store.
        //FirmnessID is a foreign key to the list specified above.
        $scope.rec = {
           "id": 1,
           "FirmnessID": 2
        };

This is all I needed to get the desired result:

        <select ng-model="rec.FirmnessID"
                ng-options="g.FirmnessID as g.Description for g in list">
            <option></option>
        </select>   

Notice I did not use track by. Using track by the selected item would alway return the object that matched the FirmnessID, rather than the FirmnessID itself. This now meets my criteria, which is that it should return a numeric value rather than the object, and to use ng-options to gain the performance improvement it provides by not creating a new scope for each option generated.

Also, I needed the blank first row, so I simply added an <option> to the <select> element.

Here is a Plunkr that shows my work.

Starting with 0.21.0, using .loc or [] with a list with one or more missing labels is deprecated in favor of .reindex. So, the answer to your question is:

df1 = df.reindex(columns=['b','c'])

In prior versions, using .loc[list-of-labels] would work as long as at least one of the keys was found (otherwise it would raise a KeyError). This behavior is deprecated and now shows a warning message. The recommended alternative is to use .reindex().

beforeShowDate didn't work for me, so I went ahead and developed my own solution:

$('#embeded_calendar').datepicker({
               minDate: date,
                localToday:datePlusOne,
               changeDate: true,
               changeMonth: true,
               changeYear: true,
               yearRange: "-120:+1",
               onSelect: function(selectedDateFormatted){

                     var selectedDate = $("#embeded_calendar").datepicker('getDate');

                    deactivateDates(selectedDate);
                   }

           });


              var excludedDates = [ "10-20-2017","10-21-2016", "11-21-2016"];

              deactivateDates(new Date());

            function deactivateDates(selectedDate){
                setTimeout(function(){ 
                      var thisMonthExcludedDates = thisMonthDates(selectedDate);
                      thisMonthExcludedDates = getDaysfromDate(thisMonthExcludedDates);
                       var excludedTDs = page.find('td[data-handler="selectDay"]').filter(function(){
                           return $.inArray( $(this).text(), thisMonthExcludedDates) >= 0
                       });

                       excludedTDs.unbind('click').addClass('ui-datepicker-unselectable');
                   }, 10);
            }

            function thisMonthDates(date){
              return $.grep( excludedDates, function( n){
                var dateParts = n.split("-");
                return dateParts[0] == date.getMonth() + 1  && dateParts[2] == date.getYear() + 1900;
            });
            }

            function getDaysfromDate(datesArray){
                  return  $.map( datesArray, function( n){
                    return n.split("-")[1]; 
                });
             }

In new code assignment should be,

B[0] = 5

In func(B), you are just passing address of the pointer which is pointing to array B. You can do change in func() as B[i] or *(B + i). Where i is the index of the array.

In the first code the declaration says,

int *B[10]

says that B is an array of 10 elements, each element of which is a pointer to a int. That is, B[i] is a int pointer and *B[i] is the integer it points to the first integer of the i-th saved text line.

I would suggest to end java.exe or javaw.exe process from task manager and try again. This will not end the entire eclipse application but will free the port.

Apache 2 mod_headers

You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:

# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful

On Ubuntu/Debian you can configure headers in the file /etc/apache2/conf-enabled/security.conf

#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"

#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"

Note: This is the bottom part of the file. Only the last three entries are CSP settings.

The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.

Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.

While you're at it you could take a look at the other header settings and install mod_security

I came up with this three liner.

Essentially, here's what it does:

1. Fetch the column names and their respective data types.
2. I am optionally outputting it to a csv.

inp = pd.read_csv('filename.csv') # read input. Add read_csv arguments as needed
columns = pd.DataFrame({'column_names': inp.columns, 'datatypes': inp.dtypes})
columns.to_csv(inp+'columns_list.csv', encoding='utf-8') # encoding is optional

This made my life much easier in trying to generate schemas on the fly. Hope this helps

I've found more elegant solution here. Adapted to the question it may look like:

$neededObject = array_filter(
    $arrayOfObjects,
    function ($e) use ($searchedValue) {
        return $e->id == $searchedValue;
    }
);

Vincent Povirk's answer won't work completely;

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
...

You have to change it in:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgdata = archive.read('img_01.png')
...

For details read the ZipFile docs here.

Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...

For example,

curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz

Was looking for an Answer as well, but all I could find was outdated.

This Issue is solved since HTML5: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/datalist

<label>Choose a browser from this list:
<input list="browsers" name="myBrowser" /></label>
<datalist id="browsers">
  <option value="Chrome">
  <option value="Firefox">
  <option value="Internet Explorer">
  <option value="Opera">
  <option value="Safari">
  <option value="Microsoft Edge">
</datalist>

If I had not found that, I would have gone with this approach:

http://www.dhtmlgoodies.com/scripts/form_widget_editable_select/form_widget_editable_select.html

json_decode($jsondata, true);

true turns all properties to array (sequential or not)

#include <chrono>
#include <iostream>

int main()
{
    std::time_t ct = std::time(0);
    char* cc = ctime(&ct);

    std::cout << cc << std::endl;
    return 0;
}

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

I don't think I saw anyone suggest this and the OP just said "script" so...

I needed to solve the same problem and my most comfortable language is Python.

I used the paramiko library. Furthermore, I also needed to issue commands for which I would need escalated permissions using sudo. It turns out sudo can accept its password via stdin via the "-S" flag! See below:

import paramiko

ssh_client = paramiko.SSHClient()

# To avoid an "unknown hosts" error. Solve this differently if you must...
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# This mechanism uses a private key.
pkey = paramiko.RSAKey.from_private_key_file(PKEY_PATH)

# This mechanism uses a password.
# Get it from cli args or a file or hard code it, whatever works best for you
password = "password"

ssh_client.connect(hostname="my.host.name.com",
                       username="username",
                       # Uncomment one of the following...
                       # password=password
                       # pkey=pkey
                       )

# do something restricted
# If you don't need escalated permissions, omit everything before "mkdir"
command = "echo {} | sudo -S mkdir /var/log/test_dir 2>/dev/null".format(password)

# In order to inspect the exit code
# you need go under paramiko's hood a bit
# rather than just using "ssh_client.exec_command()"
chan = ssh_client.get_transport().open_session()
chan.exec_command(command)

exit_status = chan.recv_exit_status()

if exit_status != 0:
    stderr = chan.recv_stderr(5000)

# Note that sudo's "-S" flag will send the password prompt to stderr
# so you will see that string here too, as well as the actual error.
# It was because of this behavior that we needed access to the exit code
# to assert success.

    logger.error("Uh oh")
    logger.error(stderr)
else:
    logger.info("Successful!")

Hope this helps someone. My use case was creating directories, sending and untarring files and starting programs on ~300 servers as a time. As such, automation was paramount. I tried sshpass, expect, and then came up with this.

You can use toLocaleString(). This is a javascript method.

var event = new Date("01/02/1993");_x000D_
_x000D_
var options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };_x000D_
_x000D_
console.log(event.toLocaleString('en', options));_x000D_
_x000D_
// expected output: "Saturday, January 2, 1993"

Almost all formats supported. Have look on this link for more details.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString

-XX:MaxPermSize=size

Sets the maximum permanent generation space size (in bytes). This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.

-XX:PermSize=size

Sets the space (in bytes) allocated to the permanent generation that triggers a garbage collection if it is exceeded. This option was deprecated in JDK 8, and superseded by the -XX:MetaspaceSize option.

This link (How to get line count cheaply in Python?) has lots of potential solutions, but they all ignore one way to make this run considerably faster, namely by using the unbuffered (raw) interface, using bytearrays, and doing your own buffering.

Using a modified version of the timing tool, I believe the following code is faster (and marginally more pythonic) than any of the solutions offered:

def _make_gen(reader):
    b = reader(1024 * 1024)
    while b:
        yield b
        b = reader(1024*1024)

def rawpycount(filename):
    f = open(filename, 'rb')
    f_gen = _make_gen(f.raw.read)
    return sum( buf.count(b'\n') for buf in f_gen )

Here are my timings:

rawpycount        0.0048  0.0046   1.00
bufcount          0.0074  0.0066   1.43
wccount             0.01    0.01   2.17
itercount          0.014   0.014   3.04
opcount            0.021    0.02   4.43
kylecount          0.023   0.021   4.58
simplecount        0.022   0.022   4.81
mapcount           0.038   0.032   6.82

I would post it there, but I'm a relatively new user to stack exchange and don't have the requisite manna.

EDIT:

This can be done completely with generators expressions in-line using itertools, but it gets pretty weird looking:

from itertools import (takewhile,repeat)

def rawbigcount(filename):
    f = open(filename, 'rb')
    bufgen = takewhile(lambda x: x, (f.raw.read(1024*1024) for _ in repeat(None)))
    return sum( buf.count(b'\n') for buf in bufgen if buf )

I added a "Height" to my ListBox and it added the scrollbar nicely.

rpm -ql [packageName]

Example

# rpm -ql php-fpm

No need to install yum-utils, or to know the location of the rpm file.

I had this issue, it seems that I hadn't added the required NuGet packages, although I thought I had done so, make sure to check them, one by one.

First of all, you should install SignalR.Host.Self on the server application and SignalR.Client on your client application by nuget :

PM> Install-Package SignalR.Hosting.Self -Version 0.5.2

PM> Install-Package Microsoft.AspNet.SignalR.Client

Then add the following code to your projects ;)

(run the projects as administrator)

Server console app:

using System;
using SignalR.Hubs;

namespace SignalR.Hosting.Self.Samples {
    class Program {
        static void Main(string[] args) {
            string url = "http://127.0.0.1:8088/";
            var server = new Server(url);

            // Map the default hub url (/signalr)
            server.MapHubs();

            // Start the server
            server.Start();

            Console.WriteLine("Server running on {0}", url);

            // Keep going until somebody hits 'x'
            while (true) {
                ConsoleKeyInfo ki = Console.ReadKey(true);
                if (ki.Key == ConsoleKey.X) {
                    break;
                }
            }
        }

        [HubName("CustomHub")]
        public class MyHub : Hub {
            public string Send(string message) {
                return message;
            }

            public void DoSomething(string param) {
                Clients.addMessage(param);
            }
        }
    }
}

Client console app:

using System;
using SignalR.Client.Hubs;

namespace SignalRConsoleApp {
    internal class Program {
        private static void Main(string[] args) {
            //Set connection
            var connection = new HubConnection("http://127.0.0.1:8088/");
            //Make proxy to hub based on hub name on server
            var myHub = connection.CreateHubProxy("CustomHub");
            //Start connection

            connection.Start().ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error opening the connection:{0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine("Connected");
                }

            }).Wait();

            myHub.Invoke<string>("Send", "HELLO World ").ContinueWith(task => {
                if (task.IsFaulted) {
                    Console.WriteLine("There was an error calling send: {0}",
                                      task.Exception.GetBaseException());
                } else {
                    Console.WriteLine(task.Result);
                }
            });

            myHub.On<string>("addMessage", param => {
                Console.WriteLine(param);
            });

            myHub.Invoke<string>("DoSomething", "I'm doing something!!!").Wait();


            Console.Read();
            connection.Stop();
        }
    }
}

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:

Unfortunately, it's not completely portable. It's usually integral, but it can be any "integer or real-floating type".

Sure. You could use CSS3 text-shadow :

text-shadow: 0 0 2px #fff;

However it wont show in all browsers right away. Using a script library like Modernizr will help getting it right in most browsers though.

What you want to do is use the HTML5 attribute placeholder which lets you set a default value for your input box:

<input type="text" name="inputBox" placeholder="enter your text here">

This should achieve what you're looking for. However, be careful because the placeholder attribute is not supported in Internet Explorer 9 and earlier versions.

You can use Android Intents library for opening your application page at Google Play like that:

Intent intent = IntentUtils.openPlayStore(getApplicationContext());
startActivity(intent);

If that version you need to obtain is either a branch or a tag then:

git clone -b branch_or_tag_name repo_address_or_path

@Acyra- performance of object delivery from a single bucket would depend greatly on the names of the objects in it.

If the file names were distanced by random characters then their physical locations would be spread further on the AWS hardware, but if you named everything 'common-x.jpg', 'common-y.jpg' then those objects will be stored together.

This may slow delivery of the files if you request them simultaneously but not by enough to worry you, the greater risk is from data-loss or an outage, since these objects are stored together they will be lost or unavailable together.

If you want to have access to the id attribute of the button you can leverage the srcElement property of the event:

import {Component} from 'angular2/core';

@Component({
  selector: 'my-app',
  template: `
    <button (click)="onClick($event)" id="test">Click</button>
  `
})
export class AppComponent {
  onClick(event) {
    var target = event.target || event.srcElement || event.currentTarget;
    var idAttr = target.attributes.id;
    var value = idAttr.nodeValue;
  }
}

Simulation = For analysis and study

Emulation = For usage as a substitute

A simulator is an environment which models but an emulator is one that replicates the usage as on the original device or system.

Simulator mimics the activity of something that it is simulating. It "appears"(a lot can go with this "appears", depending on the context) to be the same as the thing being simulated. For example the flight simulator "appears" to be a real flight to the user, although it does not transport you from one place to another.

Emulator, on the other hand, actually "does" what the thing being emulated does, and in doing so it too "appears to be doing the same thing". An emulator may use different set of protocols for mimicking the thing being emulated, but the result/outcome is always the same as the original object. For example, EMU8086 emulates the 8086 microprocessor on your computer, which obviously is not running on 8086 (= different protocols), but the output it gives is what a real 8086 would give.

Actually you can do it.

Although, someone should note that repeating the CASE statements are not bad as it seems. SQL Server's query optimizer is smart enough to not execute the CASE twice so that you won't get any performance hit because of that.

Additionally, someone might use the following logic to not repeat the CASE (if it suits you..)

INSERT INTO dbo.T1
(
    Col1,
    Col2,
    Col3
)
SELECT
    1,
    SUBSTRING(MyCase.MergedColumns, 0, CHARINDEX('%', MyCase.MergedColumns)),
    SUBSTRING(MyCase.MergedColumns, CHARINDEX('%', MyCase.MergedColumns) + 1, LEN(MyCase.MergedColumns) - CHARINDEX('%', MyCase.MergedColumns))
FROM
    dbo.T1 t
LEFT OUTER JOIN
(
    SELECT CASE WHEN 1 = 1 THEN '2%3' END MergedColumns
) AS MyCase ON 1 = 1

This will insert the values (1, 2, 3) for each record in the table T1. This uses a delimiter '%' to split the merged columns. You can write your own split function depending on your needs (e.g. for handling null records or using complex delimiter for varchar fields etc.). But the main logic is that you should join the CASE statement and select from the result set of the join with using a split logic.

the simplest solution is.....open your website in vs2013 and go to Debug->WebsiteProperties (last option) a new window will open..

in this window go to "Build" option and change .net framework version from 4.5 to 4.0.....then select ok. [note: this step will only work if your project does not have dependencies with vs2013...]

Now open your website in vs2010

If you want convert from Json to a typed ArrayList , it's wrong to specify the type of the object contained in the list. The correct syntax is as follows:

 Gson gson = new Gson(); 
 List<MyClass> myList = gson.fromJson(inputString, ArrayList.class);

push() is for arrays, not objects, so use the right data structure.

var data = [];
// ...
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };
// ...
var tempData = [];
for ( var index=0; index<data.length; index++ ) {
    if ( data[index].Status == "Valid" ) {
        tempData.push( data );
    }
}
data = tempData;

Select CONVERT(VARCHAR(8), GETDATE(), 112)

It's really just a coding style. The compiler generates the exact same for both variants.

See also here for the performance question:

• Will using 'var' affect performance?

Since there's no way to just pass this "comma-separated list of varchars", I assume some other system is generating them. If you can modify your generator slightly, it should be workable. Rather than separating by commas, you separate by union all select, and need to prepend a select also to the list. Finally, you need to provide aliases for the table and column in you subselect:

Create Table #IMEIS(
    imei varchar(15)
)
INSERT INTO #IMEIS(imei)
    SELECT * FROM (select '012251000362843' union all select '012251001084784' union all select '012251001168744' union all
                   select '012273007269862' union all select '012291000080227' union all select '012291000383084' union all
                   select '012291000448515') t(Col)
SELECT * from #IMEIS
DROP TABLE #IMEIS;

But noting your comment to another answer, about having 5000 entries to add. I believe the 256 tables per select limitation may kick in with the above "union all" pattern, so you'll still need to do some splitting of these values into separate statements.

When you have two or more windows open horizontally or vertically and want to switch them all to the other orientation, you can use the following:

(switch to horizontal)

:windo wincmd K

(switch to vertical)

:windo wincmd H

It's effectively going to each window individually and using ^WK or ^WH.

Providing you know the index value of the beginning and end of each word you wish to replace in the character array, and you only wish to replace that particular chunk of data, you could do it like this.

>>> s = "papa is papa is papa"
>>> s = s[:8]+s[8:13].replace("papa", "mama")+s[13:]
>>> print(s)
papa is mama is papa

Alternatively, if you also wish to retain the original data structure, you could store it in a dictionary.

>>> bin = {}
>>> s = "papa is papa is papa"
>>> bin["0"] = s
>>> s = s[:8]+s[8:13].replace("papa", "mama")+s[13:]
>>> print(bin["0"])
papa is papa is papa
>>> print(s)
papa is mama is papa

Use pyplot.suptitle or Figure.suptitle:

import matplotlib.pyplot as plt
import numpy as np

fig=plt.figure()
data=np.arange(900).reshape((30,30))
for i in range(1,5):
    ax=fig.add_subplot(2,2,i)        
    ax.imshow(data)

fig.suptitle('Main title') # or plt.suptitle('Main title')
plt.show()

Yes. But place your "test" after the comma if you want the column...

> A <- matrix(sample(1:12,12,T),ncol=4)

> rownames(A) <- letters[1:3]

> colnames(A) <- letters[11:14]
> A[,"l"]
 a  b  c 
 6 10  1

If you are using Razor view engine then edit the _Layout.cshtml file. Move the @Scripts.Render("~/bundles/jquery") present in footer to the header section and write the javascript / jquery code as you want:

@Scripts.Render("~/bundles/jquery")
<script type="text/javascript">
    $(document).ready(function () {
        var divLength = $('div').length;
        alert(divLength);
    });
</script>

One other thing to note, if you updated a legacy app that had structs to use classes you might run into the following issue:

Old code has structs, code was cleaned up and these changed to classes. A virtual function or two was then added to the new updated class.

When virtual functions are in classes then internally the compiler will add extra pointer to the class data to point to the functions.

How this would break old legacy code is if in the old code somewhere the struct was cleared using memfill to clear it all to zeros, this would stomp the extra pointer data as well.

copy structure in c you just need to assign the values as follow:

struct RTCclk RTCclk1;
struct RTCclk RTCclkBuffert;

RTCclk1.second=3;
RTCclk1.minute=4;
RTCclk1.hour=5;

RTCclkBuffert=RTCclk1;

now RTCclkBuffert.hour will have value 5,

RTCclkBuffert.minute will have value 4

RTCclkBuffert.second will have value 3

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

1. Open Excel workbook.
2. Alt+F11 to open VBA/Macros window.
3. Add reference to regex under Tools then References
   
4. and selecting Microsoft VBScript Regular Expression 5.5
   
5. Insert a new module (code needs to reside in the module otherwise it doesn't work).
   
6. In the newly inserted module,
   

7. add the following code:

   Function RegxFunc(strInput As String, regexPattern As String) As String
       Dim regEx As New RegExp
       With regEx
           .Global = True
           .MultiLine = True
           .IgnoreCase = False
           .pattern = regexPattern
       End With
   
       If regEx.Test(strInput) Then
           Set matches = regEx.Execute(strInput)
           RegxFunc = matches(0).Value
       Else
           RegxFunc = "not matched"
       End If
   End Function
   

8. The regex pattern is placed in one of the cells and absolute referencing is used on it. Function will be tied to workbook that its created in.
   If there's a need for it to be used in different workbooks, store the function in Personal.XLSB

jQuery:

  document.body.appendChild(div);
  $(div).css({
   position: 'absolute',
   left: -1000,
   top: -1000,
   display: 'none'
  });

  $(div).html($(el).html());
  var styles = ['font-size','font-style', 'font-weight', 'font-family','line-height', 'text-transform', 'letter-spacing'];
  $(styles).each(function() {
   var s = this.toString();
   $(div).css(s, $(el).css(s));
  });

  h = $(div).outerHeight();
  w = $(div).outerWidth();

  $(div).remove();

  var ret = {

At first I thought the Paste Special was the holy grail! But then I tried it and my hair turned white just like the Indiana Jones movie.

But now I use http://xmltocsharp.azurewebsites.net/ and now I'm as young as ever.

Here's a segment of what it generated:

namespace Xml2CSharp
{
    [XmlRoot(ElementName="entry")]
    public class Entry {
        [XmlElement(ElementName="hybrisEntryID")]
        public string HybrisEntryID { get; set; }
        [XmlElement(ElementName="mapicsLineSequenceNumber")]
        public string MapicsLineSequenceNumber { get; set; }

The following works for me:

public virtual void Send(string fileName, byte[] file)
{
    ByteArrayToFile(fileName, file);

    var request = (FtpWebRequest) WebRequest.Create(new Uri(ServerUrl + fileName));

    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.UsePassive = false;
    request.Credentials = new NetworkCredential(UserName, Password);
    request.ContentLength = file.Length;

    var requestStream = request.GetRequestStream();
    requestStream.Write(file, 0, file.Length);
    requestStream.Close();

    var response = (FtpWebResponse) request.GetResponse();

    if (response != null)
        response.Close();
}

You can't read send the file parameter in your code as it is only the filename.

Use the following:

byte[] bytes = File.ReadAllBytes(dir + file);

To get the file so you can pass it to the Send method.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

One option is to use bouncycastle's PEMParser:

Class for parsing OpenSSL PEM encoded streams containing X509 certificates, PKCS8 encoded keys and PKCS7 objects.

In the case of PKCS7 objects the reader will return a CMS ContentInfo object. Public keys will be returned as well formed SubjectPublicKeyInfo objects, private keys will be returned as well formed PrivateKeyInfo objects. In the case of a private key a PEMKeyPair will normally be returned if the encoding contains both the private and public key definition. CRLs, Certificates, PKCS#10 requests, and Attribute Certificates will generate the appropriate BC holder class.

Actually, I think the "ls" may be faster. There are definitely some issues in Java dealing with getting File info. Unfortunately there is no equivalent safe method of recursive ls for Windows. (cmd.exe's DIR /S can get confused and generate errors in infinite loops)

On XP, accessing a server on the LAN, it takes me 5 seconds in Windows to get the count of the files in a folder (33,000), and the total size.

When I iterate recursively through this in Java, it takes me over 5 minutes. I started measuring the time it takes to do file.length(), file.lastModified(), and file.toURI() and what I found is that 99% of my time is taken by those 3 calls. The 3 calls I actually need to do...

The difference for 1000 files is 15ms local versus 1800ms on server. The server path scanning in Java is ridiculously slow. If the native OS can be fast at scanning that same folder, why can't Java?

As a more complete test, I used WineMerge on XP to compare the modified date, and size of the files on the server versus the files locally. This was iterating over the entire directory tree of 33,000 files in each folder. Total time, 7 seconds. java: over 5 minutes.

So the original statement and question from the OP is true, and valid. Its less noticeable when dealing with a local file system. Doing a local compare of the folder with 33,000 items takes 3 seconds in WinMerge, and takes 32 seconds locally in Java. So again, java versus native is a 10x slowdown in these rudimentary tests.

Java 1.6.0_22 (latest), Gigabit LAN, and network connections, ping is less than 1ms (both in the same switch)

Java is slow.

If you think the performance of the query will be better using the index, how could you force the query to use the index?

First you would of course verify that the index gave a better result for returning the complete data set, right?

The index hint is the key here, but the more up to date way of specifying it is with the column naming method rather than the index naming method. In your case you would use:

select /*+ index(table_name (column_having_index)) */ *
from   table_name
where  column_having_index="some value"; 

In more complex cases you might ...

select /*+ index(t (t.column_having_index)) */ *
from   my_owner.table_name t,
       ...
where  t.column_having_index="some value"; 

With regard to composite indexes, I'm not sure that you need to specify all columns, but it seems like a good idea. See the docs here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#autoId18 on multiple index_specs and use of index_combine for multiple indexes, and here http://docs.oracle.com/cd/E11882_01/server.112/e26088/sql_elements006.htm#BABGFHCH for the specification of multiple columns in the index_spec.

Here is a compact, dynamic version that doesn't depend on iter (but works similarly):

package main

import (
    "fmt"
)

// N is an alias for an unallocated struct
func N(size int) []struct{} {
    return make([]struct{}, size)
}

func main() {
    size := 1000
    for i := range N(size) {
        fmt.Println(i)
    }
}

With some tweaks size could be of type uint64 (if needed) but that's the gist.

Here is what I had and what caused my "incomplete type error":

#include "X.h" // another already declared class
class Big {...} // full declaration of class A

class Small : Big {
    Small() {}
    Small(X); // line 6
}
//.... all other stuff

What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..

Big.cpp

Small::Big(X my_x) { // line 9 <--- LOOK at this !
}

I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..

Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.

Check Collections#sort method. This automatically sorts your list according to natural ordering. You can apply this method on each sublist you obtain using List#subList method.

private List<String> teamsName = new ArrayList<String>();
List<String> subList = teamsName.subList(1, teamsName.size());
Collections.sort(subList);

The real problem here is that there is a bug in hibernate where it uses select-list aliases in the where-clause:

http://opensource.atlassian.com/projects/hibernate/browse/HHH-817

Just in case someone lands here looking for answers, go look at the ticket. It took 5 years to fix but in theory it'll be in one of the next releases and then I suspect your issue will go away.

if (ActionsLogWriter.Close || ErrorDumpWriter.Close == true)
{    // Do stuff here
}

The problem occured on me when I had not recoginized I did call two times with different threads simultaneously .

notifyDataSetChanged

one from sqlite load function one from after calling function

So you can change it programmatically easily by using homeAsUpIndicator() function that added in android API level 18 and upper.

ActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);

If you use support library

getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);

I just added class hide to the div before "card-body" and it hidden by default.

<div id="collapseOne" class="collapse hide" aria-labelledby="headingOne" data-parent="#accordion">

You can have a look at dozer which is a

Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Another better link...

GSON is easy to use and has relatively small memory footprint. If you loke to have even smaller footprint, you can grab:

https://github.com/ko5tik/jsonserializer

Which is tiny wrapper around stripped down GSON libraries for just POJOs

Even better, use DEFAULT instead of NULL. You want to store the default value, not a NULL that might trigger a default value.

But you'd better name all columns, with a piece of SQL you can create all the INSERT, UPDATE and DELETE's you need. Just check the information_schema and construct the queries you need. There is no need to do it all by hand, SQL can help you out.

If you have an image imported as a resource in your project there is also this:

picPreview.Image = Properties.Resources.ImageName;

Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.

*Resources are located by going to: Project --> Properties --> Resources

You want to use:

git checkout --ours foo/bar.java
git add foo/bar.java

If you rebase a branch feature_x against main (i.e. running git rebase main while on branch feature_x), during rebasing ours refers to main and theirs to feature_x.

As pointed out in the git-rebase docs:

Note that a rebase merge works by replaying each commit from the working branch on top of the branch. Because of this, when a merge conflict happens, the side reported as ours is the so-far rebased series, starting with <upstream>, and theirs is the working branch. In other words, the sides are swapped.

For further details read this thread.

No.

You get charged for:

1. Online time
2. Storage space (assumably you store the image on S3 [EBS])
3. Elastic IP addresses
4. Bandwidth

So... if you stop the EC2 instance you will only have to pay for the storage of the image on S3 (assuming you store an image ofcourse) and any IP addresses you've reserved.

I assume the question is already answered. If above solution doesn't help in solving the issue then can use below to solve the issue.

The issue occurs if sometimes your maven user settings is not reflecting correct settings.xml file.

To update the settings file go to Windows > Preferences > Maven > User Settings and update the settings.xml to it correct location.

Once this is doen re-build the project, these should solve the issue. Thanks.

Small addition to all of above:

Better use map, when you need to get elements by range, as they are sorted and you can just iterate over them from one boundary to another.

When you use % for setting heights or widths, always set the widths/heights of parent elements as well:

.table {_x000D_
    display: table;_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.cell {_x000D_
    border: 2px solid black;_x000D_
    vertical-align: top;_x000D_
    display: table-cell;_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.container {_x000D_
    height: 100%;_x000D_
    border: 2px solid green;_x000D_
    -moz-box-sizing: border-box;_x000D_
}

<div class="table">_x000D_
    <div class="cell">_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
        <p>Text_x000D_
    </div>_x000D_
    <div class="cell">_x000D_
        <div class="container">Text</div>_x000D_
    </div>_x000D_
</div>

Other answers have given clear enough examples of a record referencing another record in the same table.

There are even valid use cases for a record referencing itself in the same table. For example, a point of sale system accepting many tenders may need to know which tender to use for change when the payment is not the exact value of the sale. For many tenders that's the same tender, for others that's domestic cash, for yet other tenders, no form of change is allowed.

All this can be pretty elegantly represented with a single tender attribute which is a foreign key referencing the primary key of the same table, and whose values sometimes match the respective primary key of same record. In this example, the absence of value (also known as NULL value) might be needed to represent an unrelated meaning: this tender can only be used at its full value.

Popular relational database management systems support this use case smoothly.

Take-aways:

1. When inserting a record, the foreign key reference is verified to be present after the insert, rather than before the insert.

2. When inserting multiple records with a single statement, the order in which the records are inserted matters. The constraints are checked for each record separately.

3. Certain other data patterns, such as those involving circular dependences on record level going through two or more tables, cannot be purely inserted at all, or at least not with all the foreign keys enabled, and they have to be established using a combination of inserts and updates (if they are truly necessary).

If you don't want to use apache, you can use Java8:

byte[] decodedBytes = Base64.getDecoder().decode("YWJjZGVmZw=="); 
System.out.println(new String(decodedBytes) + "\n");

A more compact and efficient way would be perhaps:

cols = ['frame', 'count']
N = 4
dat = pd.DataFrame(columns = cols)
for i in range(N):

    dat = dat.append({'frame': str(i), 'count':i},ignore_index=True)

output would be:

>>> dat
   frame count
0     0     0
1     1     1
2     2     2
3     3     3

Try using the \t character in your strings

For an uglier version of unshift use splice:

TheArray.splice(0, 0, TheNewObject);

Base on @Mark answer, I add the constructor to directive and it work with me.

I share a sample to whom concern.

constructor(private el: ElementRef, private renderer: Renderer) {
}

TS file

@Directive({ selector: '[accordion]' })
export class AccordionDirective {

  constructor(private el: ElementRef, private renderer: Renderer) {
  }

  @HostListener('click', ['$event']) onClick($event) {
    console.info($event);

    this.el.nativeElement.classList.toggle('is-open');

    var content = this.el.nativeElement.nextElementSibling;
    if (content.style.maxHeight) {
      // accordion is currently open, so close it
      content.style.maxHeight = null;
    } else {
      // accordion is currently closed, so open it
      content.style.maxHeight = content.scrollHeight + "px";

    }
  }
}

HTML

<button accordion class="accordion">Accordian #1</button>
    <div class="accordion-content">
      <p>
        Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quas deleniti molestias necessitatibus quaerat quos incidunt! Quas officiis repellat dolore omnis nihil quo,

The solution is very simple and worked for me.

Try this :

git pull --rebase <url>

then

git push -u origin master

You mention batch files, am I correct then assuming that you're talking about a Windows system? If so you cannot use sshpass, and you will have to switch to a different option.

Two of such options, that follow diametrically opposite philosophies are:

• psftp: command-line tool that you can call from within your batch scripts; psftp is part of the PuTTY package and you can find it here http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
• Syncplify.me FTP Script: a scriptable FTP/S and SFTP client for Windows that allows you to store your password in encrypted "profile files"; check it out here http://www.syncplify.me/products/ftp-script/

Either way, switching from password to PKI authentication is strongly recommended.

I just like to generate it with UTF-8 and link it to every file and folder to navigate really easily. Please take a look at the example here.

for Arabic, I used Encoding.GetEncoding(1256). it is working good.

OK, so within minutes after posting the question, I found the answer myself here: https://github.com/npm/npm/issues/2119#issuecomment-5321857

The issue seems to be that npm is not that great with HTTPS over a proxy. Changing the registry URL from HTTPS to HTTP fixed it for me:

npm config set registry http://registry.npmjs.org/

I still have to provide the proxy config (through Authoxy in my case), but everything works fine now.

Seems to be a common issue, but not well documented. I hope this answer here will make it easier for people to find if they run into this issue.

validator package:

There seems to be a nice package by Yonatan Matalon called UrlUtil. Quoting its API:

isValidWebPageAddress(java.lang.String address, boolean validateSyntax, 
                      boolean validateExistance) 
Checks if the given address is a valid web page address.

Sun's approach - check the network address

Sun's Java site offers connect attempt as a solution for validating URLs.

Other regex code snippets:

There are regex validation attempts at Oracle's site and weberdev.com.

If there is an object with 8 methods and you have a test where you want to call 7 real methods and stub one method you have two options:

1. Using a mock you would have to set it up by invoking 7 callRealMethod and stub one method
2. Using a spy you have to set it up by stubbing one method

The official documentation on doCallRealMethod recommends using a spy for partial mocks.

See also javadoc spy(Object) to find out more about partial mocks. Mockito.spy() is a recommended way of creating partial mocks. The reason is it guarantees real methods are called against correctly constructed object because you're responsible for constructing the object passed to spy() method.

Why don't you place the account number in a div. Style it as you please and then have a hidden input in the form that also contains the account number. Then when the form gets submitted, the value should come through and not be null.

You have to match the settings for PHP-FPM and Nginx to communicate over sockets or TCP.

So go to /etc/php5/fpm/pool.d/www.conf and look for this line:

listen = /var/run/php5-fpm.sock

Then go to /etc/nginx/nginx.conf

Look for this:

upstream php {
    server unix:/var/run/php5-fpm.socket;
}

Match those values and you should be all set.

Based on the answer by @Jeff, refactored to use a classmethod so that you can reuse the same code for any of your enums:

from enum import Enum

class ExtendedEnum(Enum):

    @classmethod
    def list(cls):
        return list(map(lambda c: c.value, cls))

class OperationType(ExtendedEnum):
    CREATE = 'CREATE'
    STATUS = 'STATUS'
    EXPAND = 'EXPAND'
    DELETE = 'DELETE'

print(OperationType.list())

Produces:

['CREATE', 'STATUS', 'EXPAND', 'DELETE']

from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage

msg = MIMEMultipart()
msg.attach(MIMEText(file("text.txt").read()))
msg.attach(MIMEImage(file("image.png").read()))

# to send
mailer = smtplib.SMTP()
mailer.connect()
mailer.sendmail(from_, to, msg.as_string())
mailer.close()

Adapted from here.

Here is short Scala solution:

  def bfs(nodes: List[Node]): List[Node] = {
    if (nodes.nonEmpty) {
      nodes ++ bfs(nodes.flatMap(_.children))
    } else {
      List.empty
    }
  }

Idea of using return value as accumulator is well suited. Can be implemented in other languages in similar way, just make sure that your recursive function process list of nodes.

Test code listing (using @marco test tree):

import org.scalatest.FlatSpec

import scala.collection.mutable

class Node(val value: Int) {

  private val _children: mutable.ArrayBuffer[Node] = mutable.ArrayBuffer.empty

  def add(child: Node): Unit = _children += child

  def children = _children.toList

  override def toString: String = s"$value"
}

class BfsTestScala extends FlatSpec {

  //            1
  //          / | \
  //        2   3   4
  //      / |       | \
  //    5   6       7  8
  //  / |           | \
  // 9  10         11  12
  def tree(): Node = {
    val root = new Node(1)
    root.add(new Node(2))
    root.add(new Node(3))
    root.add(new Node(4))
    root.children(0).add(new Node(5))
    root.children(0).add(new Node(6))
    root.children(2).add(new Node(7))
    root.children(2).add(new Node(8))
    root.children(0).children(0).add(new Node(9))
    root.children(0).children(0).add(new Node(10))
    root.children(2).children(0).add(new Node(11))
    root.children(2).children(0).add(new Node(12))
    root
  }

  def bfs(nodes: List[Node]): List[Node] = {
    if (nodes.nonEmpty) {
      nodes ++ bfs(nodes.flatMap(_.children))
    } else {
      List.empty
    }
  }

  "BFS" should "work" in {
    println(bfs(List(tree())))
  }
}

Output:

List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

IIS now has

Idle Time-out Action : Suspend setting

Suspending is just freezes the process and it is much more efficient than the destroying the process.

The best you can get with simple styles would be something like:

.likeabutton {
    text-decoration: none; font: menu;
    display: inline-block; padding: 2px 8px;
    background: ButtonFace; color: ButtonText;
    border-style: solid; border-width: 2px;
    border-color: ButtonHighlight ButtonShadow ButtonShadow ButtonHighlight;
}
.likeabutton:active {
    border-color: ButtonShadow ButtonHighlight ButtonHighlight ButtonShadow;
}

(Possibly with some kind of fix to stop IE6-IE7 treating focused buttons as being ‘active’.)

This won't necessarily look exactly like the buttons on the native desktop, though; indeed, for many desktop themes it won't be possible to reproduce the look of a button in simple CSS.

However, you can ask the browser to use native rendering, which is best of all:

.likeabutton {
    appearance: button;
    -moz-appearance: button;
    -webkit-appearance: button;
    text-decoration: none; font: menu; color: ButtonText;
    display: inline-block; padding: 2px 8px;
}

Unfortunately, as you may have guessed from the browser-specific prefixes, this is a CSS3 feature that isn't suppoorted everywhere yet. In particular IE and Opera will ignore it. But if you include the other styles as backup, the browsers that do support appearance drop that property, preferring the explicit backgrounds and borders!

What you might do is use the appearance styles as above by default, and do JavaScript fixups as necessary, eg.:

<script type="text/javascript">
    var r= document.documentElement;
    if (!('appearance' in r || 'MozAppearance' in r || 'WebkitAppearance' in r)) {
        // add styles for background and border colours
        if (/* IE6 or IE7 */)
            // add mousedown, mouseup handlers to push the button in, if you can be bothered
        else
            // add styles for 'active' button
    }
</script>

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

You can also write this:

SqlCommand cmd=new SqlCommand ("insert into time(project,iteration) values (@project, @iteration)", conn);
cmd.Parameters.AddWithValue("@project",name1.SelectedValue);
cmd.Parameters.AddWithValue("@iteration",iteration.SelectedValue);

Operator? NO, but I think you can change your culture so that string comparison is not case-sensitive.

// you'll want to change this...
System.Threading.Thread.CurrentThread.CurrentCulture
// and you'll want to custimize this
System.Globalization.CultureInfo.CompareInfo

I'm confident that it will change the way that strings are being compared by the equals operator.

I needed to run a specific npm script on my app in pm2 (for each env) In my case, it was when I created a staging/test service

The command that worked for me (the args must be forwarded that way):

pm2 start npm --name "my-app-name" -- run "npm:script"

examples:

pm2 start npm --name "myApp" -- run "start:test"

pm2 start npm --name "myApp" -- run "start:staging"

pm2 start npm --name "myApp" -- run "start:production"

Hope it helped

If you want to create table with data . First create the table :

create table new_table as ( select * from old_table); 

and then insert

insert into new_table ( select * from old_table);

If you want to create table without data . You can use :

create table new_table as ( select * from old_table where 1=0);

You can try using framework like jLinq - following is a code sample of using jLinq

var results = jLinq.from(data.users)
.startsWith("first", "a")
.orEndsWith("y")
.orderBy("admin", "age")
.select();

For more information you can follow the link http://www.hugoware.net/projects/jlinq

Python uses duck typing: it doesn't care about what an object is, as long as it has the appropriate interface for the situation at hand. When you call the built-in function len() on an object, you are actually calling its internal __len__ method. A custom object can implement this interface and len() will return the answer, even if the object is not conceptually a sequence.

For a complete list of interfaces, have a look here: http://docs.python.org/reference/datamodel.html#basic-customization

try this

$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd

My response is fairly late. I faced the same problem. I am on Windows 10. This is what I did:

• Open a new Command prompt (CMD.EXE)
• Set the environment variables . set myvar1=myvalue1
• Launch VS Code from that Command prompt by typing code and then press ENTER
• VS code was launched and it inherited all the custom variables that I had set in the parent CMD window

Optionally, you can also use the Control Panel -> System properties window to set the variables on a more permanent basis

Hope this helps.

def doAppend( size=10000 ):
    result = []
    for i in range(size):
        message= "some unique object %d" % ( i, )
        result.append(message)
    return result

def doAllocate( size=10000 ):
    result=size*[None]
    for i in range(size):
        message= "some unique object %d" % ( i, )
        result[i]= message
    return result

Results. (evaluate each function 144 times and average the duration)

simple append 0.0102
pre-allocate  0.0098

Conclusion. It barely matters.

Premature optimization is the root of all evil.

Refering to the very first question, I am looking into the same. The result I get, recording a macro, is, starting by selecting cell A76:

Sub find_last_row()
    Range("A76").Select
    Range(Selection, Selection.End(xlDown)).Select
End Sub

The dependency has a snapshot version. For snapshots, Maven will check the local repository and if the artifact found in the local repository is too old, it will attempt to find an updated one in the remote repositories. That is probably what you are seeing.

Note that this behavior is controlled by the updatePolicy directive in the repository configuration (which is daily by default for snapshot repositories).

I think the simplest way to just open a single database and start querying is:

sqlite> .open "test.db"
sqlite> SELECT * FROM table_name ... ;

Notice: This works only for versions 3.8.2+

  public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        alertDialog.setTitle("Error");
        alertDialog.setMessage(description);
        alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                return;
            }
        });
        alertDialog.show();
    }
});

Your ''.join() expression is filtering, removing anything non-ASCII; you could use a conditional expression instead:

return ''.join([i if ord(i) < 128 else ' ' for i in text])

This handles characters one by one and would still use one space per character replaced.

Your regular expression should just replace consecutive non-ASCII characters with a space:

re.sub(r'[^\x00-\x7F]+',' ', text)

Note the + there.

The SCSS way for all elements (not only buttons):

body {
  * {
    &:focus, &.focus,
    &:active, &.active {
      outline: transparent none 0 !important;
      box-shadow: 0 0 0 0 rgba(0,123,255,0) !important;
      -webkit-box-shadow: none !important;
    }
  }
}

I'm not quite sure if you mean 'can i use sqlite (websql) in chrome' or 'can i use sqlite (websql) in firefox', so I'll answer both:

• You cannot use WebSQL in Firefox. (sql.js is an option, but really, 1.5 mb of js for a database?)
• You can definitely use WebSQL in a chrome extension. See for instance the webkit window.openDatabase docs for an introduction

Note that WebSQL is not a full-access pipe into an .sqlite database. It's WebSQL. You will not be able to run some specific queries like VACUUM

It's awesome for Create / Read / Update / Delete though. I made a little library that helps with all the annoying nitty gritty like creating tables and querying and a provides a little ORM/ActiveRecord pattern with relations and all and a huge stack of examples that should get you started in no-time, you can check that here

Also, be aware that if you want to build a FireFox extension: Their extension format is about to change. Make sure you want to invest the time twice.

While the WebSQL spec has been deprecated for years, even now in 2017 still does not look like it will be be removed from Chrome for the foreseeable time. They are tracking usage statistics and there are still a large number of chrome extensions and websites out there in the real world implementing the spec.

For .xls use the following content-type

application/vnd.ms-excel

For Excel 2007 version and above .xlsx files format

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

Actually I wanted same alike thing, To get one year backward date, for a given date! :-)

With the hint of above answer from @mohammad mohsenipur I got to the following link, via his given link!

Luckily, there is a method same as date_add method, named date_sub method! :-) I do the following to get done what I wanted!

$date = date_create('2000-01-01');
date_sub($date, date_interval_create_from_date_string('1 years'));
echo date_format($date, 'Y-m-d');

Hopes this answer will help somebody too! :-)

Good luck guys!

What is wrong with List.Find ??

I think we need more information on what you've done, and why it fails, before we can provide truly helpful answers.

and has lower precedence, mostly we use it as a control-flow modifier such as if:

next if widget = widgets.pop

becomes

widget = widgets.pop and next

For or:

raise "Not ready!" unless ready_to_rock?

becomes

ready_to_rock? or raise "Not ready!"

I prefer to use if but not and, because if is more intelligible, so I just ignore and and or.

Refer to "Using “and” and “or” in Ruby" for more information.

use:

String[] mStrings = new String[title.length];

In JavaScript, == is pronounced "Probably Equals".

What I mean by that is that JavaScript will automatically convert the Boolean into an integer and then attempt to compare the two sides.

For real equality, use the === operator.

To take first 5 elements better use expression like this one:

var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5);

or

var firstFiveArrivals = myList.Where([EXPRESSION]).Take(5).OrderBy([ORDER EXPR]);

It will be faster than orderBy variant, because LINQ engine will not scan trough all list due to delayed execution, and will not sort all array.

class MyList : IEnumerable<int>
{

    int maxCount = 0;

    public int RequestCount
    {
        get;
        private set;
    }
    public MyList(int maxCount)
    {
        this.maxCount = maxCount;
    }
    public void Reset()

        {

            yield return i++;
        }
    }

Below is the program to execute the rest api in python-

import requests
url = 'https://url'
data = '{  "platform": {    "login": {      "userName": "name",      "password": "pwd"    }  } }'
response = requests.post(url, data=data,headers={"Content-Type": "application/json"})
print(response)
sid=response.json()['platform']['login']['sessionId']   //to extract the detail from response
print(response.text)
print(sid)

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

From Apple Docs

You can use subscript syntax to retrieve a value from the dictionary for a particular key. Because it is possible to request a key for which no value exists, a dictionary’s subscript returns an optional value of the dictionary’s value type. If the dictionary contains a value for the requested key, the subscript returns an optional value containing the existing value for that key. Otherwise, the subscript returns nil:

https://developer.apple.com/documentation/swift/dictionary

if let airportName = airports["DUB"] {
    print("The name of the airport is \(airportName).")
} else {
    print("That airport is not in the airports dictionary.")
}
// prints "The name of the airport is Dublin Airport."

Since Management Studio 2005 it seems that you can use GO with an int parameter, like:

INSERT INTO mytable DEFAULT VALUES
GO 10

The above will insert 10 rows into mytable. Generally speaking, GO will execute the related sql commands n times.

Assuming you are inside your repository root folder

alias notepad="/c/Program\ Files\ \(x86\)/Notepad++/notepad++.exe"

then you can open any file with Notepad++ with:

notepad readme.md

You can try it:

Strange. Inside OnCreate method, I'm using

webView.getSettings().setBuiltInZoomControls(true);

And it's working fine here. Anything particular in your webview ?

I test examples in js. Simplest solution - just add word u need inside / /:

var reg = /cat/;
reg.test('some cat here');//1 test
true // result
reg.test('acatb');//2 test
true // result

Now if u need this specific word with boundaries, not inside any other signs-letters. We use b marker:

var reg = /\bcat\b/
reg.test('acatb');//1 test 
false // result
reg.test('have cat here');//2 test
true // result

We have also exec() method in js, whichone returns object-result. It helps f.g. to get info about place/index of our word.

var matchResult = /\bcat\b/.exec("good cat good");
console.log(matchResult.index); // 5

If we need get all matched words in string/sentence/text, we can use g modifier (global match):

"cat good cat good cat".match(/\bcat\b/g).length
// 3 

Now the last one - i need not 1 specific word, but some of them. We use | sign, it means choice/or.

"bad dog bad".match(/\bcat|dog\b/g).length
// 1

The initialize method is called after all @FXML annotated members have been injected. Suppose you have a table view you want to populate with data:

class MyController { 
    @FXML
    TableView<MyModel> tableView; 

    public MyController() {
        tableView.getItems().addAll(getDataFromSource()); // results in NullPointerException, as tableView is null at this point. 
    }

    @FXML
    public void initialize() {
        tableView.getItems().addAll(getDataFromSource()); // Perfectly Ok here, as FXMLLoader already populated all @FXML annotated members. 
    }
}

It's not really an IDE per se, but I really like TextMate, and with the C++ bundle that ships with it, it can do a lot of the things you'd find in an IDE (without all the bloat!).

I was using Terminator before, so I found it convenient to re-map Alt + arrow-key to switch between the panes. This can be done in Preferences -> Keys -> Key Mappings - press the '+' button to add a mapping. Also, in my case such a mapping was already defined in Profiles, I simply removed it.

Have you run npm init? That command runs you through everything...

Or use a cast with split to uniform type of str

unique, counts = numpy.unique(str(a).split(), return_counts=True)

Treat function as variable in your program so you can just pass them to other functions easily:

def test ():
   print "test was invoked"

def invoker(func):
   func()

invoker(test)  # prints test was invoked

You need to parse the url first, so it goes like this:

$url = "https://www.example.com/profile#picture";
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'

If you need to parse the actual url of the current browser, you need to request to call the server.

$url = $_SERVER["REQUEST_URI"];
$fragment = parse_url($url,PHP_URL_FRAGMENT); //this variable holds the value - 'picture'

If it's just a matter of easy reading, you could always define your own function :

is.not.null <- function(x) !is.null(x)

So you can use it all along your program.

is.not.null(3)
is.not.null(NULL)

Following Python code worked for me. To check the ODBC connection, I first created a 4 line C# console application as listed below.

Python Code

import pandas as pd
import pyodbc 
cnxn = pyodbc.connect("Driver={SQL Server};Server=serverName;UID=UserName;PWD=Password;Database=RCO_DW;")
df = pd.read_sql_query('select TOP 10 * from dbo.Table WHERE Patient_Key > 1000', cnxn)
df.head()

Calling a Stored Procedure

 dfProcResult = pd.read_sql_query('exec dbo.usp_GetPatientProfile ?', cnxn, params=['MyParam'] )

C# Program to Check ODBC Connection

    static void Main(string[] args)
    {
        string connectionString = "Driver={SQL Server};Server=serverName;UID=UserName;PWD=Password;Database=RCO_DW;";
        OdbcConnection cn = new OdbcConnection(connectionString);
        cn.Open();
        cn.Close();
    }

You can use this

@echo off
for /F %%i in ('dir /b "c:\test directory\*.*"') do (
   echo Folder is NON empty
   goto :EOF
)
echo Folder is empty or does not exist

Taken from here.

That should do what you need.

You can use Ctrl + Shift + F which will run your formatter on the file and fix indentations along the way also.

The stdout of the process started by the docker container is available through the docker logs $containerid command (use -f to keep it going forever). Another option would be to stream the logs directly through the docker remote API.

For accessing log files (only if you must, consider logging to stdout or other standard solution like syslogd) your only real-time option is to configure a volume (like Marcus Hughes suggests) so the logs are stored outside the container and available for processing from the host or another container.

If you do not need real-time access to the logs, you can export the files (in tar format) with docker export

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

If you aren't looking to do anything to the stuff in the file, just display it, you can actually just include() it. include works for any file type, but of course it runs any php code it finds inside.

Due to absolute positioning removing the elements from the document flow position: absolute is not the right tool for the job. Depending on the exact layout you want to create you will be successful using negative margins, position:relative or maybe even transform: translate. Show us a sample of what you want to do we can help you better.

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

You need to specify the number of rows which should be deleted. In your case (and I assume that you only want to keep one) this can be done like this:

DELETE FROM your_table WHERE id_users=1 AND id_product=2
LIMIT (SELECT COUNT(*)-1 FROM your_table WHERE id_users=1 AND id_product=2)

You can close the connection with

mongoose.connection.close()

If we cannot instantiate generic arrays, why does the language have generic array types? What's the point of having a type without objects?

The only reason I can think of, is varargs - foo(T...). Otherwise they could have completely scrubbed generic array types. (Well, they didn't really have to use array for varargs, since varargs didn't exist before 1.5. That's probably another mistake.)

So it is a lie, you can instantiate generic arrays, through varargs!

Of course, the problems with generic arrays are still real, e.g.

static <T> T[] foo(T... args){
    return args;
}
static <T> T[] foo2(T a1, T a2){
    return foo(a1, a2);
}

public static void main(String[] args){
    String[] x2 = foo2("a", "b"); // heap pollution!
}

We can use this example to actually demonstrate the danger of generic array.

On the other hand, we've been using generic varargs for a decade, and the sky is not falling yet. So we can argue that the problems are being exaggerated; it is not a big deal. If explicit generic array creation is allowed, we'll have bugs here and there; but we've been used to the problems of erasure, and we can live with it.

And we can point to foo2 to refute the claim that the spec keeps us from the problems that they claim to keep us from. If Sun had more time and resources for 1.5, I believe they could have reached a more satisfying resolution.

Here is the simple solution by StreamEx:

StreamEx.of(list).groupingBy(Function.identity(), MoreCollectors.countingInt());

This has the advantage of reducing the Java stream boilerplate code: collect(Collectors.

Building on top of the answer by Ophir Stern, here is a variant which works with AoT in Angular 4. The only issue I have is I cant inject any services into the DynamicComponent, but I can live with that.

note: I haven't tested with Angular 5.

import { Component, OnInit, Input, NgModule, NgModuleFactory, Compiler, EventEmitter, Output } from '@angular/core';
import { JitCompilerFactory } from '@angular/compiler';

export function createJitCompiler() {
  return new JitCompilerFactory([{
    useDebug: false,
    useJit: true
  }]).createCompiler();
}

type Bindings = {
  [key: string]: any;
};

@Component({
  selector: 'app-compile',
  template: `
    <div *ngIf="dynamicComponent && dynamicModule">
      <ng-container *ngComponentOutlet="dynamicComponent; ngModuleFactory: dynamicModule;">
      </ng-container>
    </div>
  `,
  styleUrls: ['./compile.component.scss'],
  providers: [{provide: Compiler, useFactory: createJitCompiler}]
})
export class CompileComponent implements OnInit {

  public dynamicComponent: any;
  public dynamicModule: NgModuleFactory<any>;

  @Input()
  public bindings: Bindings = {};
  @Input()
  public template: string = '';

  constructor(private compiler: Compiler) { }

  public ngOnInit() {

    try {
      this.loadDynamicContent();
    } catch (err) {
      console.log('Error during template parsing: ', err);
    }

  }

  private loadDynamicContent(): void {

    this.dynamicComponent = this.createNewComponent(this.template, this.bindings);
    this.dynamicModule = this.compiler.compileModuleSync(this.createComponentModule(this.dynamicComponent));

  }

  private createComponentModule(componentType: any): any {

    const runtimeComponentModule = NgModule({
      imports: [],
      declarations: [
        componentType
      ],
      entryComponents: [componentType]
    })(class RuntimeComponentModule { });

    return runtimeComponentModule;

  }

  private createNewComponent(template: string, bindings: Bindings): any {

    const dynamicComponent = Component({
      selector: 'app-dynamic-component',
      template: template
    })(class DynamicComponent implements OnInit {

      public bindings: Bindings;

      constructor() { }

      public ngOnInit() {
        this.bindings = bindings;
      }

    });

    return dynamicComponent;

  }

}

Hope this helps.

Cheers!

A more memory efficient way to iterate over a slice of a list would be to use islice() from the itertools module:

from itertools import islice

listOfStuff = (['a','b'], ['c','d'], ['e','f'], ['g','h'])

for item in islice(listOfStuff, 1, 3):
    print item

# ['c', 'd']
# ['e', 'f']

However, this can be relatively inefficient in terms of performance if the start value of the range is a large value sinceislicewould have to iterate over the first start value-1 items before returning items.

Use capitalize. From the String documentation:

Returns a copy of str with the first character converted to uppercase and the remainder to lowercase.

"hello".capitalize    #=> "Hello"
"HELLO".capitalize    #=> "Hello"
"123ABC".capitalize   #=> "123abc"

You can try by adding following line to catalina.bat after last entry of JAVA_OPTS

set JAVA_OPTS=%JAVA_OPTS% -Dhttps.protocols=TLSv1.2 -Djdk.tls.client.protocols=TLSv1.2

Most likely as others have said you want to attach it to your Intent with putExtra. But I want to throw out there that depending on what your use case is, it may be better to have one activity that switches between two fragments. The data is stored in the activity and never has to be passed.

You should be able to do the following:

MyFragmentClass test = (MyFragmentClass) getSupportFragmentManager().findFragmentByTag("testID");
if (test != null && test.isVisible()) {
     //DO STUFF
}
else {
    //Whatever
}

This also works for https needed a solution to making project directories this was it. because chrome doesn't like non ssl anymore used free ssl. Notice: My Web Server is Wamp64 on Windows 10 so I wouldn't use this config because of variables unless your using wamp.

All the current answers clobber the non-writing permissions: they make the file readable-but-not-executable for everybody. Granted, this is because the initial question asked for 444 permissions -- but we can do better!

Here's a solution that leaves all the individual "read" and "execute" bits untouched. I wrote verbose code to make it easy to understand; you can make it more terse if you like.

import os
import stat

def remove_write_permissions(path):
    """Remove write permissions from this path, while keeping all other permissions intact.

    Params:
        path:  The path whose permissions to alter.
    """
    NO_USER_WRITING = ~stat.S_IWUSR
    NO_GROUP_WRITING = ~stat.S_IWGRP
    NO_OTHER_WRITING = ~stat.S_IWOTH
    NO_WRITING = NO_USER_WRITING & NO_GROUP_WRITING & NO_OTHER_WRITING

    current_permissions = stat.S_IMODE(os.lstat(path).st_mode)
    os.chmod(path, current_permissions & NO_WRITING)

Why does this work?

As John La Rooy pointed out,stat.S_IWUSR basically means "the bitmask for the user's write permissions". We want to set the corresponding permission bit to 0. To do that, we need the exact opposite bitmask (i.e., one with a 0 in that location, and 1's everywhere else). The ~ operator, which flips all the bits, gives us exactly that. If we apply this to any variable via the "bitwise and" operator (&), it will zero out the corresponding bit.

We need to repeat this logic with the "group" and "other" permission bits, too. Here we can save some time by just &'ing them all together (forming the NO_WRITING bit constant).

The last step is to get the current file's permissions, and actually perform the bitwise-and operation.

Boolean types can be null. You need to do a null check as you have set it to null.

if (bool != null && bool)
{
  //DoSomething
}                   

JQuery has the best datepicker IMHO. While it's not specific to .Net is still works great.

HTML:

<input type="text" value="9/23/2009" style="width: 100px;" readonly="readonly" name="Date" id="Date" class="hasDatepicker"/>

In head element:

<script src="../../Scripts/jquery-1.3.2.min.js" language="javascript" type="text/javascript"/>
<script src="../../Scripts/jquery-ui-1.7.1.custom.min.js" type="text/javascript"/>

Simple as that!

A double is an IEEE754 double-precision floating point number, similar to a float but with a larger range and precision.

IEEE754 single precision numbers have 32 bits (1 sign, 8 exponent and 23 mantissa bits) while double precision numbers have 64 bits (1 sign, 11 exponent and 52 mantissa bits).

A Double in Java is the class version of the double basic type - you can use doubles but, if you want to do something with them that requires them to be an object (such as put them in a collection), you'll need to box them up in a Double object.

In my case I was making an connection through pgAdmin with ssh tunneling and set to host field ip address but it was necessary to set localhost

For windows

• Install anaconda-clean module using

  conda install anaconda-clean
  

  then, run the following command to delete files step by step:

  anaconda-clean
  

  Or, just run following command to delete them all-

  anaconda-clean --yes
  

• After this Open Control Panel> Programs> Uninstall Program, here uninstall that python for which publisher is Anaconda.

• Now, you can remove anaconda/scripts and /anaconda/ from PATH variable.

Hope, it helps.

Evolutionary Computation Graduate Class: Developed a solution for TopCoder Marathon Match 49: MegaParty. My small group was testing different domain representations and how the different representation would affect the ga's ability to find the correct answer. We rolled our own code for this problem.

Neuroevolution and Generative and Developmental Systems, Graduate Class: Developed an Othello game board evaluator that was used in the min-max tree of a computer player. The player was set to evaluate one-deep into the game, and trained to play against a greedy computer player that considered corners of vital importance. The training player saw either 3 or 4 deep (I'll need to look at my config files to answer, and they're on a different computer). The goal of the experiment was to compare Novelty Search to traditional, fitness-based search in the Game Board Evaluation domain. Results were relatively inconclusive, unfortunately. While both the novelty search and fitness-based search methods came to a solution (showing that Novelty Search can be used in the Othello domain), it was possible to have a solution to this domain with no hidden nodes. Apparently I didn't create a sufficiently competent trainer if a linear solution was available (and it was possible to have a solution right out of the gates). I believe my implementation of Fitness-based search produced solutions more quickly than my implementation of Novelty search, this time. (this isn't always the case). Either way, I used ANJI, "Another NEAT Java Implementation" for the neural network code, with various modifications. The Othello game I wrote myself.

You can use pd.to_datetime() to convert to a datetime object. It takes a format parameter, but in your case I don't think you need it.

>>> import pandas as pd
>>> df = pd.DataFrame( {'Symbol':['A','A','A'] ,
    'Date':['02/20/2015','01/15/2016','08/21/2015']})
>>> df
         Date Symbol
0  02/20/2015      A
1  01/15/2016      A
2  08/21/2015      A
>>> df['Date'] =pd.to_datetime(df.Date)
>>> df.sort('Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

For future search, you can change the sort statement:

>>> df.sort_values(by='Date') # This now sorts in date order
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

When I tried your code, it worked.

The only reason that your event is not working, may be that your DOM was not ready and your button with id "event-btn" was not yet ready. And your javascript got executed and tried to bind the event with that element.

Before using the DOM element for binding, that element should be ready. There are many options to do that.

Option1: You can move your event binding code within document ready event. Like:

document.addEventListener('DOMContentLoaded', (event) => {
  //your code to bind the event
});

Option2: You can use timeout event, so that binding is delayed for few seconds. like:

setTimeout(function(){
  //your code to bind the event
}, 500);

Option3: move your javascript include to the bottom of your page.

I hope this helps you.

You don't have the namespace the Login class is in as a reference.

Add the following to the form that uses the Login class:

using FootballLeagueSystem;

When you want to use a class in another namespace, you have to tell the compiler where to find it. In this case, Login is inside the FootballLeagueSystem namespace, or : FootballLeagueSystem.Login is the fully qualified namespace.

As a commenter pointed out, you declare the Login class inside the FootballLeagueSystem namespace, but you're using it in the FootballLeague namespace.

Have you tried

(setq  tab-width  4)

Create an instance of Class B:

B b=new B();
b.method();

or define an static method in Class B:

class B
{
 static void staticMethod();
}

and call it like this:

B.staticMethod();
