I had the same issue, and the solution is very simple, just change to git bash from cmd or other windows command line tools. Windows sometimes does not work well with git npm dependencies.

Starting from the decoded base64 data of an OpenSSL rsa-ssh Key, i've been able to guess a format:

• 00 00 00 07: four byte length prefix (7 bytes)
• 73 73 68 2d 72 73 61: "ssh-rsa"
• 00 00 00 01: four byte length prefix (1 byte)
• 25: RSA Exponent (e): 25
• 00 00 01 00: four byte length prefix (256 bytes)

• RSA Modulus (n):

The closest validation of my theory i can find it from RFC 4253:

The "ssh-rsa" key format has the following specific encoding:

  string    "ssh-rsa"
  mpint     e
  mpint     n

Here the 'e' and 'n' parameters form the signature key blob.

But it doesn't explain the length prefixes.

Taking the random RSA PUBLIC KEY i found (in the question), and decoding the base64 into hex:

From RFC3447 - Public-Key Cryptography Standards (PKCS) #1: RSA Cryptography Specifications Version 2.1:

A.1.1 RSA public key syntax

An RSA public key should be represented with the ASN.1 type RSAPublicKey:

  RSAPublicKey ::= SEQUENCE {
     modulus           INTEGER,  -- n
     publicExponent    INTEGER   -- e
  }

The fields of type RSAPublicKey have the following meanings:

• modulus is the RSA modulus n.
• publicExponent is the RSA public exponent e.

Using Microsoft's excellent (and the only real) ASN.1 documentation:

30 82 01 0a       ;SEQUENCE (0x010A bytes: 266 bytes)
|  02 82 01 01    ;INTEGER  (0x0101 bytes: 257 bytes)
|  |  00          ;leading zero because high-bit, but number is positive

|  |  63 
|  02 03          ;INTEGER (3 bytes)
|     01 00 01

giving the public key modulus and exponent:

• modulus = 0xfb1199ff0733f6e805a4fd3b36ca68...837a63
• exponent = 65,537

Update: My expanded form of this answer in another question

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();
    }
}

I came up with this simple and elegant solution. It assumes that the activity is responsible for creating the Fragments, and the Adapter just serves them.

This is the adapter's code (nothing weird here, except for the fact that mFragments is a list of fragments maintained by the Activity)

class MyFragmentPagerAdapter extends FragmentStatePagerAdapter {

    public MyFragmentPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragments.get(position);
    }

    @Override
    public int getCount() {
        return mFragments.size();
    }

    @Override
    public int getItemPosition(Object object) {
        return POSITION_NONE;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        TabFragment fragment = (TabFragment)mFragments.get(position);
        return fragment.getTitle();
    }
} 

The whole problem of this thread is getting a reference of the "old" fragments, so I use this code in the Activity's onCreate.

    if (savedInstanceState!=null) {
        if (getSupportFragmentManager().getFragments()!=null) {
            for (Fragment fragment : getSupportFragmentManager().getFragments()) {
                mFragments.add(fragment);
            }
        }
    }

Of course you can further fine tune this code if needed, for example making sure the fragments are instances of a particular class.

I have encountered this problem as well. Here is my solution:

In order to resolve this issue you need to do the following in the controller class:-

1. Change the import package from "import org.springframework.web.portlet.ModelAndView;" to "import org.springframework.web.servlet.ModelAndView;"...
2. Recompile and run the code... the problem should get resolved.

HAVING is used to filter on aggregations in your GROUP BY.

For example, to check for duplicate names:

SELECT Name FROM Usernames
GROUP BY Name
HAVING COUNT(*) > 1

They might be just a \r or a \n. I just checked and the text visualizer in VS 2010 displays both as newlines as well as \r\n.

This string

string test = "blah\r\nblah\rblah\nblah";

Shows up as

blah
blah
blah
blah

in the text visualizer.

So you could try

string modifiedString = originalString
    .Replace(Environment.NewLine, "<br />")
    .Replace("\r", "<br />")
    .Replace("\n", "<br />");

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

in your component assign a variable like,

export class AppComponent {
  netImage:any = "../assets/network.jpg";
  title = 'app';
}

use this netImage in your src to get the image, as given below,

<figure class="figure">
  <img [src]="netImage" class="figure-img img-fluid rounded" alt="A generic square placeholder image with rounded corners in a figure.">
  <figcaption class="figure-caption">A caption for the above image.</figcaption>
</figure>

You can use:

var queryString = url.Substring(url.IndexOf('?')).Split('#')[0]
System.Web.HttpUtility.ParseQueryString(queryString)

MSDN

Office 2007

Right click the figure, select Insert Caption, Select Numbering, check box next to 'Include chapter number', select OK, Select OK again, then you figure identifier should be updated.

WebSocket is just another application level protocol over TCP protocol, just like HTTP.

Some snippets < Spring in Action 4> quoted below, hope it can help you understand WebSocket better.

In its simplest form, a WebSocket is just a communication channel between two applications (not necessarily a browser is involved)...WebSocket communication can be used between any kinds of applications, but the most common use of WebSocket is to facilitate communication between a server application and a browser-based application.

Go to management studio and do everything you describe, only instead of clicking OK, click on Script. It will show the code it will run which you can then incorporate in your scripts.

In this case, you want:

ALTER DATABASE [MyDatabase] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO

You can simply use padding-left:60% (for ex) to align your content to right and simultaneously wrap the content in responsive container (I required navbar in my case) to ensure it works in all examples.

String replace(char oldChar, char newChar)

Returns a new string resulting from replacing all occurrences of oldChar in this string with newChar.

String replaceAll(String regex, String replacement

Replaces each substring of this string that matches the given regular expression with the given replacement.

You need to specify all of the columns that you're not using for an aggregation function in your GROUP BY clause like this:

select libelle,credit_initial,disponible_v,sum(montant) as montant 
FROM fiche,annee,type where type.id_type=annee.id_type and annee.id_annee=fiche.id_annee 
and annee = year(current_timestamp) GROUP BY libelle,credit_initial,disponible_v order by libelle asc

The full_group_by mode basically makes you write more idiomatic SQL. You can turn off this setting if you'd like. There are different ways to do this that are outlined in the MySQL Documentation. Here's MySQL's definition of what I said above:

MySQL 5.7.5 and up implements detection of functional dependence. If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on them. (Before 5.7.5, MySQL does not detect functional dependency and ONLY_FULL_GROUP_BY is not enabled by default. For a description of pre-5.7.5 behavior, see the MySQL 5.6 Reference Manual.)

You're getting the error because you're on a version < 5.7.5

If you're using a relatively new version of Python, you can also use a context manager, such as this one:

from __future__ import with_statement
from grizzled.os import working_directory

with working_directory(path_to_directory):
    # code in here occurs within the directory

# code here is in the original directory

UPDATE

If you prefer to roll your own:

import os
from contextlib import contextmanager

@contextmanager
def working_directory(directory):
    owd = os.getcwd()
    try:
        os.chdir(directory)
        yield directory
    finally:
        os.chdir(owd)

Flex layout modes are not (fully) natively supported in IE yet. IE10 implements the "tween" version of the spec which is not fully recent, but still works.

https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes

This CSS-Tricks article has some advice on cross-browser use of flexbox (including IE): http://css-tricks.com/using-flexbox/

edit: after a bit more research, IE10 flexbox layout mode implemented current to the March 2012 W3C draft spec: http://www.w3.org/TR/2012/WD-css3-flexbox-20120322/

The most current draft is a year or so more recent: http://dev.w3.org/csswg/css-flexbox/

it's very easy code .. but hard to fined..

detailsApp.controller("SchoolCtrl", function ($scope, $location) { 
      $scope.addSchool = function () {

        location.href='/ManageSchool/TeacherProfile?ID=' + $scope.TeacherID;
      }
});

I am using Eclipse mars, Hibernate 5.2.1, Jdk7 and Oracle 11g.

I get the same error when I run Hibernate code generation tool. I guess it is a versions issue due to I have solved it through choosing Hibernate version (5.1 to 5.0) in the type frame in my Hibernate console configuration.

Scenario: Your domain: mydomain.com Domain you wish to send to: theirdomain.com

1. Determine the mail server you're sending to. Open a CMD prompt Type

NSLOOKUP 
 set q=mx 
 theirdomain.com

Response:

Non-authoritative answer: 
theirdomain.com MX preference = 50, mail exchanger = mail.theirdomain.com 
Nslookup_big

EDIT Be sure to type exit to terminate NSLOOKUP.

2. Connect to their mail server

SMTP communicates over port 25. We will now try to use TELNET to connect to their mail server "mail.theirdomain.com"

Open a CMD prompt

TELNET MAIL.THEIRDOMAIN.COM 25

You should see something like this as a response:

220 mx.google.com ESMTP 6si6253627yxg.6

Be aware that different servers will come up with different greetings but you should get SOMETHING. If nothing comes up at this point there are 2 possible problems. Port 25 is being blocked at your firewall, or their server is not responding. Try a different domain, if that works then it's not you.

3. Send an Email

Now, use simple SMTP commands to send a test email. This is very important, you CANNOT use the backspace key, it will work onscreen but not be interpreted correctly. You have to type these commands perfectly.

ehlo mydomain.com 
mail from:<[email protected]> 
rcpt to:<[email protected]> 
data 
This is a test, please do not respond
. 
quit

So, what does that all mean? EHLO - introduce yourself to the mail server HELO can also be used but EHLO tells the server to use the extended command set (not that we're using that).

MAIL FROM - who's sending the email. Make sure to place this is the greater than/less than brackets as many email servers will require this (Postini).

RCPT TO - who you're sending it to. Again you need to use the brackets. See Step #4 on how to test relaying mail!

DATA - tells the SMTP server that what follows is the body of your email. Make sure to hit "Enter" at the end.

. - the period alone on the line tells the SMTP server you're all done with the data portion and it's clear to send the email.

quit - exits the TELNET session.

4. Test SMTP relay Testing SMTP relay is very easy, and simply requires a small change to the above commands. See below:

ehlo mydomain.com 
mail from:<[email protected]> 
rcpt to:<[email protected]> 
data 
This is a test, please do not respond 
. 
quit

See the difference? On the RCPT TO line, we're sending to a domain that is not controlled by the SMTP server we're sending to. You will get an immediate error is SMTP relay is turned off. If you're able to continue and send an email, then relay is allowed by that server.

Simplest way is to cast the Object to any, like this:

const data = {"Ticket-1.pdf":"8e6e8255-a6e9-4626-9606-4cd255055f71.pdf","Ticket-2.pdf":"106c3613-d976-4331-ab0c-d581576e7ca1.pdf"};
const obj = <any>Object;
const values = obj.values(data).map(x => x.substr(0, x.length - 4));
const commaJoinedValues = values.join(',');
console.log(commaJoinedValues);

And voila – no compilation errors ;)

You can find the list of formats here (in the Double.ToString()-MSDN-Article) as comments in the example section.

SharpSSH is a pure .NET implementation of the SSH2 client protocol suite. It provides an API for communication with SSH servers and can be integrated into any .NET application.

The library is a C# port of the JSch project from JCraft Inc. and is released under BSD style license.

SharpSSH allows you to read/write data and transfer files over SSH channels using an API similar to JSch's API. In addition, it provides some additional wrapper classes which offer even simpler abstraction for SSH communication.

This issue is occurring because we don't have Entity Framework installed. Please install Entity Framework using the below command.

Install-Package EntityFramework -IncludePrerelease

Once installed, choose the project in the package manger console default project drop down.

Make sure at least one class in your project inherits from data context, otherwise use the below class:

public class MyDbContext : DbContext
    {
        public MyDbContext()
        {
        }
    }

If we don't do this we will get another error:

No context type was found in the assembly

After completing these things you can run

enable-migrations

// find the first select and bind a click handler
$('#column_select').bind('click', function(){
    // retrieve the selected value
    var value = $(this).val(),
        // build a regular expression that does a head-match
        expression = new RegExp('^' + value),
        // find the second select
        $select = $('#layout_select);

    // hide all children (<option>s) of the second select,
    // check each element's value agains the regular expression built from the first select's value
    // show elements that match the expression
    $select.children().hide().filter(function(){
      return !!$(this).val().match(expression);
    }).show();
});

(this is far from perfect, but should get you there…)

You are trying to pass pointers (which you do not delete, thus leaking memory) where references are needed. You do not really need pointers here:

Complex firstComplexNumber(81, 93);
Complex secondComplexNumber(31, 19);

cout << "Numarul complex este: " << firstComplexNumber << endl;
//                                  ^^^^^^^^^^^^^^^^^^ No need to dereference now

// ...

Complex::distanta(firstComplexNumber, secondComplexNumber);

I ran into this problem with templated classes. Here's a more general solution I had to use:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // Friend means operator<< can use private variables
    // It needs to be declared as a template, but T is taken
    template <class U>
    friend std::ostream& operator<<(std::ostream&, const myClass<U> &);
}

// Operator is a non-member and global, so it's not myClass<U>::operator<<()
// Because of how C++ implements templates the function must be
// fully declared in the header for the linker to resolve it :(
template <class U>
std::ostream& operator<<(std::ostream& os, const myClass<U> & obj)
{
  obj.toString(os);
  return os;
}

Now: * My toString() function can't be inline if it is going to be tucked away in cpp. * You're stuck with some code in the header, I couldn't get rid of it. * The operator will call the toString() method, it's not inlined.

The body of operator<< can be declared in the friend clause or outside the class. Both options are ugly. :(

Maybe I'm misunderstanding or missing something, but just forward-declaring the operator template doesn't link in gcc.

This works too:

template class <T>
class myClass
{
    int myField;

    // Helper function accessing my fields
    void toString(std::ostream&) const;

    // For some reason this requires using T, and not U as above
    friend std::ostream& operator<<(std::ostream&, const myClass<T> &)
    {
        obj.toString(os);
        return os;
    }
}

I think you can also avoid the templating issues forcing declarations in headers, if you use a parent class that is not templated to implement operator<<, and use a virtual toString() method.

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;

For more details refer to: http://www.postgresql.org/docs/9.2/static/sql-copy.html

This will remove all double quotes.

Use heroku's fork

1. Use the new "heroku fork" command! It will copy all the environment and you have to update the github repo after!

   heroku fork -a sourceapp targetapp
   

2. Clone it local

   git clone [email protected]:youamazingapp.git
   

3. Make a new repo on github and add it

   git remote add origin https://github.com/yourname/your_repo.git
   

4. Push on github

   git push origin master
   

I moved configuration to code to enable easy modification from CI using system variable. I used this code for file name and result is 'Log_03-23-2020.log'

            log4net.Repository.ILoggerRepository repository = LogManager.GetRepository(Assembly.GetEntryAssembly());
            Hierarchy hierarchy = (Hierarchy)repository;
            PatternLayout patternLayout = new PatternLayout();
            patternLayout.ConversionPattern = "%date %level - %message%newline%exception";
            patternLayout.ActivateOptions();

            RollingFileAppender roller = new RollingFileAppender();
            roller.AppendToFile = true;
            roller.File = "Log_";
            roller.DatePattern = "MM-dd-yyyy'.log'";
            roller.Layout = patternLayout;
            roller.MaxFileSize = 1024*1024*10;
            roller.MaxSizeRollBackups = 10;
            roller.StaticLogFileName = false;
            roller.RollingStyle = RollingFileAppender.RollingMode.Composite;
            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);

by using css we can easily add width to the column.

here im adding first column width to 300px on header (thead)

::ng-deep  table thead tr:last-child th:nth-child(1) {_x000D_
    width: 300px!important;_x000D_
}

now add same width to tbody first column by,

  <table datatable class="display table ">_x000D_
            <thead>_x000D_
            <tr>_x000D_
                <th class="text-left" style="width: 300px!important;">name</th>_x000D_
            </tr>_x000D_
            </thead>_x000D_
            <tbody>_x000D_
           _x000D_
            <tr>_x000D_
                <td class="text-left" style="width: 300px!important;">jhon mathew</td>_x000D_
                _x000D_
            </tr>_x000D_
            </tbody>_x000D_
        </table>_x000D_
       

by this way you can easily change width by changing the order of nth child. if you want 3 column then ,add nth-child(3)

You probably should not use your own function here. Use find() from STL.

Example:

list L;
L.push_back(3);
L.push_back(1);
L.push_back(7);

list::iterator result = find(L.begin(), L.end(), 7);
assert(result == L.end() || *result == 7);

the above solutions wont work on ipad-2

recently I had an safari browser crash issue while plotting the markers even if there are less number of markers. Initially I was using marker with label (markerwithlabel.js) library for plotting the marker , when i use google native marker it was working fine even with large number of markers but i want customized markers , so i refer the above solution given by jonathan but still the crashing issue is not resolved after doing lot of research i came to know about http://nickjohnson.com/b/google-maps-v3-how-to-quickly-add-many-markers this blog and now my map search is working smoothly on ipad-2 :)

There are multiple solution exist but none of them perfect. let's go one by one.

1. Unique Telephony Number (IMEI, MEID, ESN, IMSI)

• This solution needs to request for android.permission.READ_PHONE_STATE to your user which can be hard to justify following the type of application you have made.

• Furthermore, this solution is limited to smartphones because tablets don’t have telephony services. One advantage is that the value survives to factory resets on devices.

2. MAC Address

• You can also try to get a MAC Address from a device having a Wi-Fi or Bluetooth hardware. But, this solution is not recommended because not all of the device have Wi-Fi connection. Even if the user have a Wi-Fi connection, it must be turned on to retrieve the data. Otherwise, the call doesn’t report the MAC Address.

3. Serial Number

• Devices without telephony services like tablets must report a unique device ID that is available via android.os.Build.SERIAL since Android 2.3 Gingerbread. Some phones having telephony services can also define a serial number. Like not all Android devices have a Serial Number, this solution is not reliable.

4. Secure Android ID

• On a device first boot, a randomly value is generated and stored. This value is available via Settings.Secure.ANDROID_ID . It’s a 64-bit number that should remain constant for the lifetime of a device. ANDROID_ID seems a good choice for a unique device identifier because it’s available for smartphones and tablets.

  String androidId = Settings.Secure.getString(getContentResolver(),Settings.Secure.ANDROID_ID);
  

• However, the value may change if a factory reset is performed on the device. There is also a known bug with a popular handset from a manufacturer where every instance have the same ANDROID_ID. Clearly, the solution is not 100% reliable.

5. Use UUID

• As the requirement for most of applications is to identify a particular installation and not a physical device, a good solution to get unique id for an user if to use UUID class. The following solution has been presented by Reto Meier from Google in a Google I/O presentation :

  private static String uniqueID = null;
  private static final String PREF_UNIQUE_ID = "PREF_UNIQUE_ID";
  public synchronized static String id(Context context) {
     if (uniqueID == null) {
         SharedPreferences sharedPrefs = context.getSharedPreferences(
                 PREF_UNIQUE_ID, Context.MODE_PRIVATE);
         uniqueID = sharedPrefs.getString(PREF_UNIQUE_ID, null);
         if (uniqueID == null) {
             uniqueID = UUID.randomUUID().toString();
             Editor editor = sharedPrefs.edit();
             editor.putString(PREF_UNIQUE_ID, uniqueID);
             editor.commit();
         }
     }    return uniqueID;
  }
  

Identify a particular device on Android is not an easy thing. There are many good reasons to avoid that. Best solution is probably to identify a particular installation by using UUID solution. credit : blog

I've got this exact error, but in my case I was binding values for the LIMIT clause without specifying the type. I'm just dropping this here in case somebody gets this error for the same reason. Without specifying the type LIMIT :limit OFFSET :offset; resulted in LIMIT '10' OFFSET '1'; instead of LIMIT 10 OFFSET 1;. What helps to correct that is the following:

$stmt->bindParam(':limit', intval($limit, 10), \PDO::PARAM_INT);
$stmt->bindParam(':offset', intval($offset, 10), \PDO::PARAM_INT);

I know this was answered already, but I just ran into the same issue trying to specify the schema to use for the liquibase command line.

Update As of JDBC v9.4 you can specify the url with the new currentSchema parameter like so:

jdbc:postgresql://localhost:5432/mydatabase?currentSchema=myschema

Appears based on an earlier patch:

http://web.archive.org/web/20141025044151/http://postgresql.1045698.n5.nabble.com/Patch-to-allow-setting-schema-search-path-in-the-connectionURL-td2174512.html

Which proposed url's like so:

jdbc:postgresql://localhost:5432/mydatabase?searchpath=myschema

@echo off 
    setlocal enableextensions disabledelayedexpansion

    set "search=%1"
    set "replace=%2"

    set "textFile=Input.txt"

    for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
        set "line=%%i"
        setlocal enabledelayedexpansion
        >>"%textFile%" echo(!line:%search%=%replace%!
        endlocal
    )

for /f will read all the data (generated by the type comamnd) before starting to process it. In the subprocess started to execute the type, we include a redirection overwritting the file (so it is emptied). Once the do clause starts to execute (the content of the file is in memory to be processed) the output is appended to the file.

If you are on a system that has Gnome keyring app a solution that avoids exposing the password directly is to use gkeyring.py to extract the password from the keyring:

server=server.example.com
file=path/to/my/file
user=my_user_name
pass=$(gkeyring.py -k login -tnetwork -p user=$user,server=$server -1)

curl -u $user:$pass ftps://$server/$file -O

You are on the right track. Since you said you can't modify the global settings, then the next best thing is to apply the JsonConverter attribute on an as-needed basis, as you suggested. It turns out Json.Net already has a built-in IsoDateTimeConverter that lets you specify the date format. Unfortunately, you can't set the format via the JsonConverter attribute, since the attribute's sole argument is a type. However, there is a simple solution: subclass the IsoDateTimeConverter, then specify the date format in the constructor of the subclass. Apply the JsonConverter attribute where needed, specifying your custom converter, and you're ready to go. Here is the entirety of the code needed:

class CustomDateTimeConverter : IsoDateTimeConverter
{
    public CustomDateTimeConverter()
    {
        base.DateTimeFormat = "yyyy-MM-dd";
    }
}

If you don't mind having the time in there also, you don't even need to subclass the IsoDateTimeConverter. Its default date format is yyyy'-'MM'-'dd'T'HH':'mm':'ss.FFFFFFFK (as seen in the source code).

I had this error because in my test I had two expectations, one on a mock and one on concrete type

MyClass cls = new MyClass();
MyClass cls2 = Mockito.mock(Myclass.class);
when(foo.bar(cls)).thenReturn(); // cls is not actually a mock
when(foo.baz(cls2)).thenReturn();

I fixed it by changing cls to be a mock as well

You're missing comma (,) inbetween:

>>> ((1,2) (2,3))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable

Put comma:

>>> ((1,2), (2,3))
((1, 2), (2, 3))

Delete .vs/Config folder => work for me

Although the above solutions are effective, you can also modify the webconfig file with the following...

<configuration>
   <system.web>
     <globalization culture="en-GB"/>
   </system.web>
</configuration>

My Kotlin extension . write once use everywhere

fun EditText.tooglePassWord() {
this.tag = !((this.tag ?: false) as Boolean)
this.inputType = if (this.tag as Boolean)
    InputType.TYPE_TEXT_VARIATION_PASSWORD
else
    (InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD)

this.setSelection(this.length()) }

You can keep this method in any file and use it everywhere use it like this

ivShowPassword.click { etPassword.tooglePassWord() }

where ivShowPassword is clicked imageview (eye) and etPassword is Editext

The DOCKER solution:

It looks like docker-compose 1.5+ has enabled variables substitution: https://github.com/docker/compose/releases

The latest Docker Compose allows you to access environment variables from your compose file. So you can source your environment variables, then run Compose like so:

set -a
source .my-env
docker-compose up -d

Then you can reference the variables in docker-compose.yml using ${VARIABLE}, like so:

db:
  image: "postgres:${POSTGRES_VERSION}"

And here is more info from the docs, taken here: https://docs.docker.com/compose/compose-file/#variable-substitution

When you run docker-compose up with this configuration, Compose looks for the POSTGRES_VERSION environment variable in the shell and substitutes its value in. For this example, Compose resolves the image to postgres:9.3 before running the configuration.

If an environment variable is not set, Compose substitutes with an empty string. In the example above, if POSTGRES_VERSION is not set, the value for the image option is postgres:.

Both $VARIABLE and ${VARIABLE} syntax are supported. Extended shell-style features, such as ${VARIABLE-default} and ${VARIABLE/foo/bar}, are not supported.

If you need to put a literal dollar sign in a configuration value, use a double dollar sign ($$).

And I believe this feature was added in this pull request: https://github.com/docker/compose/pull/1765

The BASH solution:

I notice folks have issues with Docker's environment variables support. Instead of dealing with environment variables in Docker, let's go back to basics, like bash! Here is a more flexible method using a bash script and a .env file.

An example .env file:

EXAMPLE_URL=http://example.com
# Note that the variable below is commented out and will not be used:
# EXAMPLE_URL=http://example2.com 
SECRET_KEY=ABDFWEDFSADFWWEFSFSDFM

# You can even define the compose file in an env variable like so:
COMPOSE_CONFIG=my-compose-file.yml
# You can define other compose files, and just comment them out
# when not needed:
# COMPOSE_CONFIG=another-compose-file.yml

then run this bash script in the same directory, which should deploy everything properly:

#!/bin/bash

docker rm -f `docker ps -aq -f name=myproject_*`
set -a
source .env
cat ${COMPOSE_CONFIG} | envsubst | docker-compose -f - -p "myproject" up -d

Just reference your env variables in your compose file with the usual bash syntax (ie ${SECRET_KEY} to insert the SECRET_KEY from the .env file).

Note the COMPOSE_CONFIG is defined in my .env file and used in my bash script, but you can easily just replace {$COMPOSE_CONFIG} with the my-compose-file.yml in the bash script.

Also note that I labeled this deployment by naming all of my containers with the "myproject" prefix. You can use any name you want, but it helps identify your containers so you can easily reference them later. Assuming that your containers are stateless, as they should be, this script will quickly remove and redeploy your containers according to your .env file params and your compose YAML file.

Update Since this answer seems pretty popular, I wrote a blog post that describes my Docker deployment workflow in more depth: http://lukeswart.net/2016/03/lets-deploy-part-1/ This might be helpful when you add more complexity to a deployment configuration, like nginx configs, LetsEncrypt certs, and linked containers.

POST means "create new" as in "Here is the input for creating a user, create it for me".

PUT means "insert, replace if already exists" as in "Here is the data for user 5".

You POST to example.com/users since you don't know the URL of the user yet, you want the server to create it.

You PUT to example.com/users/id since you want to replace/create a specific user.

POSTing twice with the same data means create two identical users with different ids. PUTing twice with the same data creates the user the first and updates him to the same state the second time (no changes). Since you end up with the same state after a PUT no matter how many times you perform it, it is said to be "equally potent" every time - idempotent. This is useful for automatically retrying requests. No more 'are you sure you want to resend' when you push the back button on the browser.

A general advice is to use POST when you need the server to be in control of URL generation of your resources. Use PUT otherwise. Prefer PUT over POST.

Tensorflow 2.x support's Eager Execution by default hence Session is not supported.

Upcasting (using (Employee)someInstance) is generally easy as the compiler can tell you at compile time if a type is derived from another.

Downcasting however has to be done at run time generally as the compiler may not always know whether the instance in question is of the type given. C# provides two operators for this - is which tells you if the downcast works, and return true/false. And as which attempts to do the cast and returns the correct type if possible, or null if not.

To test if an employee is a manager:

Employee m = new Manager();
Employee e = new Employee();

if(m is Manager) Console.WriteLine("m is a manager");
if(e is Manager) Console.WriteLine("e is a manager");

You can also use this

Employee someEmployee = e  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (e) is a manager");

Employee someEmployee = m  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (m) is a manager");

Further to the other answers, you can also use "background". This is particularly useful when you want to set other properties relating to the way the image is used by the background, such as:

$("myObject").css("background", "transparent url('"+imageURL+"') no-repeat right top");

An absolute xpath in HTML DOM starts with /html e.g.

/html/body/div[5]/div[2]/div/div[2]/div[2]/h2[1]

and a relative xpath finds the closed id to the dom element and generates xpath starting from that element e.g.

.//*[@id='answers']/h2[1]/a[1]

You can use firepath (firebug) for generating both types of xpaths

It won't make any difference which xpath you use in selenium, the former may be faster than the later one (but it won't be observable)

Absolute xpaths are prone to more regression as slight change in DOM makes them invalid or refer to a wrong element

This is because in Mac OS X there is already Apache pre-installed. So what you can do is to change the listening port of one of the Apaches, either the Apache that you installed with XAMPP or the pre-installed one.

To change the listening port for XAMPP's Apache, go to /Applications/XAMPP/xamppfiles/etc and edit httpd.conf. Change the line "Listen 80" (80 is the listening port) to other port, eg. "Listen 1234".

Or,

To change the one for pre-installed Apache, go to /etc/apache2. You can do the same thing with file httpd.conf there.

After changing you might need to restart your Mac, just to make sure.

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

You need to store all of the extra rows in the files in your dictionary, not just one of them:

dict1 = {row[0]: row[1:] for row in r}
...
dict2 = {row[0]: row[1:] for row in r}

Then, since the values in the dictionaries are lists, you need to just concatenate the lists together:

w.writerows([[key] + dict1.get(key, []) + dict2.get(key, []) for key in keys])

Number number;
try {
    number = NumberFormat.getInstance().parse("123");
} catch (ParseException e) {
    //not a number - do recovery.
    e.printStackTrace();
}
//use number

One Idea:

UPDATE tbl_ClientNotes
SET ordering=ISNULL(@ordering, ordering), 
    title=ISNULL(@title, title),  
    content=ISNULL(@content, content)
WHERE id=@id

The reason the solution you found on the internet is no working is because of the line that starts var colCount. The variable mytable only has two elements being <thead> and <tbody>. The var colCount line is looking for all the elements within mytable that are <tr>. The best thing you can do is give an id to your <thead> and <tbody> and then grab all the values based on that. Say you had <thead id='headers'> :

function write_headers_to_excel() 
{
  str="";

  var myTableHead = document.getElementById('headers');
  var rowCount = myTableHead.rows.length;
  var colCount = myTableHead.getElementsByTagName("tr")[0].getElementsByTagName("th").length; 

var ExcelApp = new ActiveXObject("Excel.Application");
var ExcelSheet = new ActiveXObject("Excel.Sheet");
ExcelSheet.Application.Visible = true;

for(var i=0; i<rowCount; i++) 
{   
    for(var j=0; j<colCount; j++) 
    {           
        str= myTableHead.getElementsByTagName("tr")[i].getElementsByTagName("th")[j].innerHTML;
        ExcelSheet.ActiveSheet.Cells(i+1,j+1).Value = str;
    }
}

}

and then do the same thing for the <tbody> tag.

EDIT: I would also highly recommend using jQuery. It would shorten this up to:

function write_to_excel() 
{
 var ExcelApp = new ActiveXObject("Excel.Application");
 var ExcelSheet = new ActiveXObject("Excel.Sheet");
 ExcelSheet.Application.Visible = true; 

  $('th, td').each(function(i){
    ExcelSheet.ActiveSheet.Cells(i+1,i+1).Value = this.innerHTML;
  });
}

Now, of course, this is going to give you some formatting issues but you can work out how you want it formatted in Excel.

EDIT: To answer your question about how to do this for n number of tables, the jQuery will do this already. To do it in raw Javascript, grab all the tables and then alter the function to be able to pass in the table as a parameter. For instance:

var tables = document.getElementsByTagName('table');
for(var i = 0; i < tables.length; i++)
{
  write_headers_to_excel(tables[i]);
  write_bodies_to_excel(tables[i]);
}

Then change the function write_headers_to_excel() to function write_headers_to_excel(table). Then change var myTableHead = document.getElementById('headers'); to var myTableHead = table.getElementsByTagName('thead')[0];. Same with your write_bodies_to_excel() or however you want to set that up.

Try this,

$('td').click(function(){
   var row_index = $(this).parent().index();
   var col_index = $(this).index();
});

If you need the index of table contain td then you can change it to

var row_index = $(this).parent('table').index(); 

Have posted the same answer in two other similar questions. The way I prefer to do this is to wrap up the return values of the function in a series:

def f(x):
    return pd.Series([x**2, x**3])

And then use apply as follows to create separate columns:

df[['x**2','x**3']] = df.apply(lambda row: f(row['x']), axis=1)

AND will return you an answer only when both volunteer and uploaded are present in your column. Otherwise it will return null value...

try using OR in your statement ...

SELECT contactid  WHERE flag = 'Volunteer' OR flag = 'Uploaded'

There is also a compact form for that, if you do not want to rely on strlen. Assuming that the character array you are considering is "msg":

  unsigned int len=0;
  while(*(msg+len) ) len++;

A cronjob could monitor this log and based on events created by your trigger it could invoke a php script. That is if you absolutely have no control over you insertion.. If you have transaction logs in you MySQL, you can create a trigger for purpose of a log instance creation.

Roughly you can do it like that :

try
{
    //do something
}
catch (Exception ex)
{
    string script = "<script>alert('" + ex.Message + "');</script>";
    if (!Page.IsStartupScriptRegistered("myErrorScript"))
    {
         Page.ClientScript.RegisterStartupScript("myErrorScript", script);
    }
}

But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.

For your first question there are at least three common methods to choose from:

• NOT EXISTS
• NOT IN
• LEFT JOIN

The SQL looks like this:

SELECT * FROM TableA WHERE NOT EXISTS (
    SELECT NULL
    FROM TableB
    WHERE TableB.ID = TableA.ID
)

SELECT * FROM TableA WHERE ID NOT IN (
    SELECT ID FROM TableB
)

SELECT TableA.* FROM TableA 
LEFT JOIN TableB
ON TableA.ID = TableB.ID
WHERE TableB.ID IS NULL

Depending on which database you are using, the performance of each can vary. For SQL Server (not nullable columns):

NOT EXISTS and NOT IN predicates are the best way to search for missing values, as long as both columns in question are NOT NULL.

Any Table ID

Use: INT(11).

MySQL indexes will be able to parse through an int list fastest.

Anything Security

Use: BINARY(x), or BLOB(x).

You can store security tokens, etc., as hex directly in BINARY(x) or BLOB(x). To retrieve from binary-type, use SELECT HEX(field)... or SELECT ... WHERE field = UNHEX("ABCD....").

Anything Date

Use: DATETIME, DATE, or TIME.

Always use DATETIME if you need to store both date and time (instead of a pair of fields), as a DATETIME indexing is more amenable to date-comparisons in MySQL.

Anything True-False

Use: BIT(1) (MySQL 8-only.) Otherwise, use BOOLEAN(1).

BOOLEAN is actually just an alias of TINYINT(1), which actually stores 0 to 255 (not exactly a true/false, is it?).

Anything You Want to call `SUM()`, `MAX()`, or similar functions on

Use: INT(11).

VARCHAR or other types of fields won't work with the SUM(), etc., functions.

Anything Over 1,000 Characters

Use: TEXT.

Max limit is 65,535.

Anything Over 65,535 Characters

Use: MEDIUMTEXT.

Max limit is 16,777,215.

Anything Over 16,777,215 Characters

Use: LONGTEXT.

Max limit is 4,294,967,295.

FirstName, LastName

Use : VARCHAR(255).

UTF-8 characters can take up three characters per visible character, and some cultures do not distinguish firstname and lastname. Additionally, cultures may have disagreements about which name is first and which name is last. You should name these fields Person.GivenName and Person.FamilyName.

Email Address

Use : VARCHAR(256).

The definition of an e-mail path is set in RFC821 in 1982. The maximum limit of an e-mail was set by RFC2821 in 2001, and these limits were kept unchanged by RFC5321 in 2008. (See the section: 4.5.3.1. Size Limits and Minimums.) RFC3696, published 2004, mistakenly cites the email address limit as 320 characters, but this was an "info-only" RFC that explicitly "defines no standards" according to its intro, so disregard it.

Phone

Use: VARCHAR(255).

You never know when the phone number will be in the form of "1800...", or "1-800", or "1-(800)", or if it will end with "ext. 42", or "ask for susan".

ZipCode

Use: VARCHAR(10).

You'll get data like 12345 or 12345-6789. Use validation to cleanse this input.

URL

Use: VARCHAR(2000).

Official standards support URL's much longer than this, but few modern browsers support URL's over 2,000 characters. See this SO answer: What is the maximum length of a URL in different browsers?

Price

Use: DECIMAL(11,2).

It goes up to 11.

It is possible and is deceptively easy:

1. "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties ? Publish. This will create an installer for a ClickOnce application.
2. But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj).
3. Zip that folder (leave out any *.vhost.* files and the app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.

An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.

It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.

Swift has its own Date type. No need to use NSDate.

Creating a Date and Time in Swift

In Swift, dates and times are stored in a 64-bit floating point number measuring the number of seconds since the reference date of January 1, 2001 at 00:00:00 UTC. This is expressed in the Date structure. The following would give you the current date and time:

let currentDateTime = Date()

For creating other date-times, you can use one of the following methods.

Method 1

If you know the number of seconds before or after the 2001 reference date, you can use that.

let someDateTime = Date(timeIntervalSinceReferenceDate: -123456789.0) // Feb 2, 1997, 10:26 AM

Method 2

Of course, it would be easier to use things like years, months, days and hours (rather than relative seconds) to make a Date. For this you can use DateComponents to specify the components and then Calendar to create the date. The Calendar gives the Date context. Otherwise, how would it know what time zone or calendar to express it in?

// Specify date components
var dateComponents = DateComponents()
dateComponents.year = 1980
dateComponents.month = 7
dateComponents.day = 11
dateComponents.timeZone = TimeZone(abbreviation: "JST") // Japan Standard Time
dateComponents.hour = 8
dateComponents.minute = 34

// Create date from components
let userCalendar = Calendar(identifier: .gregorian) // since the components above (like year 1980) are for Gregorian
let someDateTime = userCalendar.date(from: dateComponents)

Other time zone abbreviations can be found here. If you leave that blank, then the default is to use the user's time zone.

Method 3

The most succinct way (but not necessarily the best) could be to use DateFormatter.

let formatter = DateFormatter()
formatter.dateFormat = "yyyy/MM/dd HH:mm"
let someDateTime = formatter.date(from: "2016/10/08 22:31")

The Unicode technical standards show other formats that DateFormatter supports.

Notes

See my full answer for how to display the date and time in a readable format. Also read these excellent articles:

• How to work with dates and times in Swift 3, part 1: Dates, Calendars, and DateComponents
• How to work with dates and times in Swift 3, part 2: DateFormatter

You need to tell npm that "tsc" exists as a local project package (via the "scripts" property in your package.json) and then run it via npm run tsc. To do that (at least on Mac) I had to add the path for the actual compiler within the package, like this

{
  "name": "foo"
  "scripts": {
    "tsc": "./node_modules/typescript/bin/tsc"
  },
  "dependencies": {
    "typescript": "^2.3.3",
    "typings": "^2.1.1"
  }
}

After that you can run any TypeScript command like npm run tsc -- --init (the arguments come after the first --).

1. Your call to MessageBox.Show needs to pass MessageBoxButtons.YesNo to get the Yes/No buttons instead of the OK button.

2. Compare the result of that call (which will block execution until the dialog returns) to DialogResult.Yes....

if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
    // user clicked yes
}
else
{
    // user clicked no
}

One way or another you must tell boto3 in which region you wish the kms client to be created. This could be done explicitly using the region_name parameter as in:

kms = boto3.client('kms', region_name='us-west-2')

or you can have a default region associated with your profile in your ~/.aws/config file as in:

[default]
region=us-west-2

or you can use an environment variable as in:

export AWS_DEFAULT_REGION=us-west-2

but you do need to tell boto3 which region to use.

just copy the above code. just call them easily

colour_print('easy one','OKCYAN')
colour_print('copy and paste','OKGREEN')
colour_print('done','OKBLUE')

Hope it would help

Better yet, consider sp_getapplock which is designed for this. Or use SET LOCK_TIMEOUT

Otherwise, you'd have to do something with sys.dm_tran_locks which I'd use only for DBA stuff: not for user defined concurrency.

auto was a keyword that C++ "inherited" from C that had been there nearly forever, but virtually never used because there were only two possible conditions: either it wasn't allowed, or else it was assumed by default.

The use of auto to mean a deduced type was new with C++11.

At the same time, auto x = initializer deduces the type of x from the type of initializer the same way as template type deduction works for function templates. Consider a function template like this:

template<class T>
int whatever(T t) { 
    // point A
};

At point A, a type has been assigned to T based on the value passed for the parameter to whatever. When you do auto x = initializer;, the same type deduction is used to determine the type for x from the type of initializer that's used to initialize it.

This means that most of the type deduction mechanics a compiler needs to implement auto were already present and used for templates on any compiler that even sort of attempted to implement C++98/03. As such, adding support for auto was apparently fairly easy for essentially all the compiler teams--it was added quite quickly, and there seem to have been few bugs related to it either.

When this answer was originally written (in 2011, before the ink was dry on the C++ 11 standard) auto was already quite portable. Nowadays, it's thoroughly portable among all the mainstream compilers. The only obvious reasons to avoid it would be if you need to write code that's compatible with a C compiler, or you have a specific need to target some niche compiler that you know doesn't support it (e.g., a few people still write code for MS-DOS using compilers from Borland, Watcom, etc., that haven't seen significant upgrades in decades). If you're using a reasonably current version of any of the mainstream compilers, there's no reason to avoid it at all though.

Sendmail wasn't working for me so I used msmtp 1.6.2 w32 and most just followed the instructions at DeveloperSide. Here is a quick rundown of the setup for posterity:

Enabled IMAP access under your Gmail account (the one msmtp is sending emails from)

Enable access for less secure apps. Log into your google account and go here

Edit php.ini, find and change each setting below to reflect the following:

; These are commented out by prefixing a semicolon
;SMTP = localhost
;smtp_port = 25

; Set these paths to where you put your msmtp files.
; I used backslashes in php.ini and it works fine.
; The example in the devside guide uses forwardslashes. 
sendmail_path = "C:\wamp64\msmtp\msmtp.exe -d -C C:\wamp64\msmtp\msmtprc.ini -t --read-envelope-from"

mail.log = "C:\wamp64\msmtp\maillog.txt"

Create and edit the file msmtprc.ini in the same directory as your msmtp.exe file as follows, replacing it with your own email and password:

# Default values for all accounts
defaults
tls_certcheck off
# I used forward slashes here and it works.
logfile C:/wamp64/msmtp/msmtplog.txt

account Gmail
host smtp.gmail.com
port 587

Android IntentService vs Service

1.Service

• A Service is invoked using startService().
• A Service can be invoked from any thread.
• A Service runs background operations on the Main Thread of the Application by default. Hence it can block your Application’s UI.
• A Service invoked multiple times would create multiple instances.
• A service needs to be stopped using stopSelf() or stopService().
• Android service can run parallel operations.

2. IntentService

• An IntentService is invoked using Intent.
• An IntentService can in invoked from the Main thread only.
• An IntentService creates a separate worker thread to run background operations.
• An IntentService invoked multiple times won’t create multiple instances.
• An IntentService automatically stops after the queue is completed. No need to trigger stopService() or stopSelf().
• In an IntentService, multiple intent calls are automatically Queued and they would be executed sequentially.
• An IntentService cannot run parallel operation like a Service.

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

I hope this helps someone. Thank you.

Truth values can be described using a Boolean algebra. The article also contains tables for and and or. This should help you to get started or to get even more confused.

For SQL Server 2000:

SELECT   su.name,so.name,so.crdate,* 
FROM     sysobjects so JOIN sysusers su
ON       so.uid = su.uid
WHERE    xtype='U'
ORDER BY so.name

\df+ <function_name> in psql.

Most code I've seen is camelCase functions (lower case initial letter), and ProperCase/PascalCase class names, and (most usually), snake_case variables.

But, to be honest, this is all just guidance. The single most important thing is to be consistent across your code base. Pick what seems natural / works for you, and stick to it. If you're joining a project in progress, follow their standards.

So something interesting that I found a while ago while working with canvas that might be helpful:

To resize the canvas control on its own, you need to use the height="" and width="" attributes (or canvas.width/canvas.height elements). If you use CSS to resize the canvas, it will actually stretch (i.e.: resize) the content of the canvas to fit the full canvas (rather than simply increasing or decreasing the area of the canvas.

It'd be worth a shot to try drawing the image into a canvas control with the height and width attributes set to the size of the image and then using CSS to resize the canvas to the size you're looking for. Perhaps this would use a different resizing algorithm.

It should also be noted that canvas has different effects in different browsers (and even different versions of different browsers). The algorithms and techniques used in the browsers is likely to change over time (especially with Firefox 4 and Chrome 6 coming out so soon, which will place heavy emphasis on canvas rendering performance).

In addition, you may want to give SVG a shot, too, as it likely uses a different algorithm as well.

Best of luck!

SetDate will sets the day of the month. Using setDate during start and end of the month,will result in wrong week

var curr = new Date("08-Jul-2014"); // get current date
var first = curr.getDate() - curr.getDay(); // First day is the day of the month - the day of the week
var last = first + 6; // last day is the first day + 6
var firstday = new Date(curr.setDate(first)); // 06-Jul-2014
var lastday = new Date(curr.setDate(last)); //12-Jul-2014

If u setting Date is 01-Jul-2014, it will show firstday as 29-Jun-2014 and lastday as 05-Jun-2014 instead of 05-Jul-2014

So overcome this issue i used

var curr = new Date();
day = curr.getDay();
firstday = new Date(curr.getTime() - 60*60*24* day*1000); //will return firstday (ie sunday) of the week
lastday = new Date(curr.getTime() + 60 * 60 *24 * 6 * 1000); //adding (60*60*6*24*1000) means adding six days to the firstday which results in lastday (saturday) of the week

Here is a solution to the literal question of how to print a message to the browser's error console, not the debugger console. (There might be good reasons to bypass the debugger.)

As I noted in comments about the suggestion to throw an error to get a message in the error console, one problem is that this will interrupt the thread of execution. If you don't want to interrupt the thread, you can throw the error in a separate thread, one created using setTimeout. Hence my solution (which turns out to be an elaboration of the one by Ivo Danihelka):

var startTime = (new Date()).getTime();
function logError(msg)
{
  var milliseconds = (new Date()).getTime() - startTime;
  window.setTimeout(function () {
    throw( new Error(milliseconds + ': ' + msg, "") );
  });
}
logError('testing');

I include the time in milliseconds since the start time because the timeout could skew the order in which you might expect to see the messages.

The second argument to the Error method is for the filename, which is an empty string here to prevent output of the useless filename and line number. It is possible to get the caller function but not in a simple browser independent way.

It would be nice if we could display the message with a warning or message icon instead of the error icon, but I can't find a way to do that.

Another problem with using throw is that it could be caught and thrown away by an enclosing try-catch, and putting the throw in a separate thread avoids that obstacle as well. However, there is yet another way the error could be caught, which is if the window.onerror handler is replaced with one that does something different. Can't help you there.

It's actually quite easy, assuming you have an openssl installation handy. (What platform are you on?)

Assuming you're on linux/solaris/mac os/x, Van's Apache SSL/TLS mini-HOWTO has an excellent walkthrough that I won't reproduce here.

However, the executive summary is that you have to create a self-signed certificate. Since you're running apache for localhost presumably for development (i.e. not a public web server), you'll know that you can trust the self-signed certificate and can ignore the warnings that your browser will throw at you.

In VS2015, this worked to turn the Enter key into <br>

myCKEControl.EnterMode = CKEditor.NET.EnterMode.BR

Personally, I don't care if my resulting text only has <br> and not <p>. It renders perfectly fine and it looks the way I want it to. In the end, it works.

Here's my version in vanilla JS (tested on Chrome)

works with:

• name="input"
• name="form[name]" (creates an object)
• name="checkbox[]" (creates an object with an array)
• name="form[checkbox][]" (creates an array)
• name="form[select][name]" (creates an object with an object containing only the selected value)

                    if ( i !== lastRun && arrayKeys[i + 1] === '[]' )

                }

                if ( i !== lastRun ) // Until we're the last item, swap container with it's child
                {
                    container = container[_key];

An instance variable is a variable that is a member of an instance of a class (i.e., associated with something created with a new), whereas a class variable is a member of the class itself.

Every instance of a class will have its own copy of an instance variable, whereas there is only one of each static (or class) variable, associated with the class itself.

What’s the difference between a class variable and an instance variable?

This test class illustrates the difference:

public class Test {
   
    public static String classVariable = "I am associated with the class";
    public String instanceVariable = "I am associated with the instance";
    
    public void setText(String string){
        this.instanceVariable = string;
    }
    
    public static void setClassText(String string){
        classVariable = string;
    }
    
    public static void main(String[] args) {
        Test test1 = new Test();
        Test test2 = new Test();
        
        // Change test1's instance variable
        test1.setText("Changed");
        System.out.println(test1.instanceVariable); // Prints "Changed"
        // test2 is unaffected
        System.out.println(test2.instanceVariable); // Prints "I am associated with the instance"
        
        // Change class variable (associated with the class itself)
        Test.setClassText("Changed class text");
        System.out.println(Test.classVariable); // Prints "Changed class text"
        
        // Can access static fields through an instance, but there still is only one
        // (not best practice to access static variables through instance)
        System.out.println(test1.classVariable); // Prints "Changed class text"
        System.out.println(test2.classVariable); // Prints "Changed class text"
    }
}

This can happen in more than one scenario, below is a list of well known scenarios :

// calling empty on a function 
empty(myFunction($myVariable)); // the return value of myFunction should be saved into a variable
// then you can use empty on your variable

// using parenthesis to access an element of an array, parenthesis are used to call a function

if (isset($_POST('sms_code') == TRUE ) { ...
// that should be if(isset($_POST['sms_code']) == TRUE)

This also could be triggered when we try to increment the result of a function like below:

$myCounter = '356';

$myCounter = intVal($myCounter)++; // we try to increment the result of the intVal...
// like the first case, the ++ needs to be called on a variable, a variable should hold the the return of the function then we can call ++ operator on it.

You can use Newtonsoft library and use it as follows

using Newtonsoft.Json;



public class jb
{
     public DateTime Date { set; get; }
     public string Artist { set; get; }
     public int Year { set; get; }
     public string album { set; get; }

}
var jsonObject = new jb();

jsonObject.Date = DateTime.Now;
jsonObject.Album = "Me Against The World";
jsonObject.Year = 1995;
jsonObject.Artist = "2Pac";


System.Web.Script.Serialization.JavaScriptSerializer oSerializer =

I found that I also had to set the Access Modifier in the Resources tab to 'Public' - by default it was set to Internal and my icon only appeared in design mode but not when I ran the application.

You cant style the alt attribute directly in css. However the alt will inherit the styles of the item the alt is on or what is inherited by its parent:

    <div style="background-color:black; height: 50px; width: 50px; color:white;">_x000D_
    <img src="ouch" alt="here i am"/>_x000D_
    <div>

In the above example, the alt text will be black. However with the color:white the alt text is white.

Define the values that you don't want to be used from Chrome's user agent style in your own CSS content.

Use splatting.

I find a combination of labs and guides specification useful in many cases:

You want nothing but a grid and a background:

ggplot(diamonds, mapping = aes(x = clarity)) + 
  geom_bar(aes(fill = cut)) + 
  labs(x = NULL, y = NULL) + 
  guides(x = "none", y = "none")

You want to only suppress the tick-mark label of one or both axes:

ggplot(diamonds, mapping = aes(x = clarity)) + 
  geom_bar(aes(fill = cut)) + 
  guides(x = "none", y = "none")

You may use event handler serverclick as below

//cmdAction is the id of HTML button as below

<body>
    <form id="form1" runat="server">
        <button type="submit" id="cmdAction" text="Button1" runat="server">
            Button1
        </button>
    </form>
</body>

//cs code

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
                cmdAction.ServerClick += new EventHandler(submit_click);  
        }

        protected void submit_click(object sender, EventArgs e)
        {
            Response.Write("HTML Server Button Control");
        }
    }

The if attribute does not exist for <copy>. It should be applied to the <target>.

Below is an example of how you can use the depends attribute of a target and the if and unless attributes to control execution of dependent targets. Only one of the two should execute.

<target name="prepare-copy" description="copy file based on condition"
    depends="prepare-copy-true, prepare-copy-false">
</target>

<target name="prepare-copy-true" description="copy file based on condition"
    if="copy-condition">
    <echo>Get file based on condition being true</echo>
    <copy file="${some.dir}/true" todir="." />
</target>

<target name="prepare-copy-false" description="copy file based on false condition" 
    unless="copy-condition">
    <echo>Get file based on condition being false</echo>
    <copy file="${some.dir}/false" todir="." />
</target>

If you are using ANT 1.8+, then you can use property expansion and it will evaluate the value of the property to determine the boolean value. So, you could use if="${copy-condition}" instead of if="copy-condition".

In ANT 1.7.1 and earlier, you specify the name of the property. If the property is defined and has any value (even an empty string), then it will evaluate to true.

Prakash is correct that the declarations are the same, although a little more explanation of the pointer case might be in order.

"const int* p" is a pointer to an int that does not allow the int to be changed through that pointer. "int* const p" is a pointer to an int that cannot be changed to point to another int.

See https://isocpp.org/wiki/faq/const-correctness#const-ptr-vs-ptr-const.

I don't think execute

 git rm first_file.txt

is a good idea.

1. when git notice your files is unmerged, you should ensure you had committed it.

2. And then open the conflict file:

   cat first_file.txt

3. fix the conflict

4.

git add file

git commit -m "fix conflict"

5. git push

it should works for you.

java.time

The java.time framework in Java 8 and later supplants the old java.util.Date/.Calendar classes. The old classes have proven to be troublesome, confusing, and flawed. Avoid them.

The java.time framework is inspired by the highly-successful Joda-Time library, defined by JSR 310, extended by the ThreeTen-Extra project, and explained in the Tutorial.

Instant

The Instant class represents a moment on the timeline in UTC.

The java.time framework has a resolution of nanoseconds, or 9 digits of a fractional second. Milliseconds is only 3 digits of a fractional second. Because millisecond resolution is common, java.time includes a handy factory method.

long millisecondsSinceEpoch = 1446959825213L;
Instant instant = Instant.ofEpochMilli ( millisecondsSinceEpoch );

millisecondsSinceEpoch: 1446959825213 is instant: 2015-11-08T05:17:05.213Z

ZonedDateTime

To consider current week and current month, we need to apply a particular time zone.

ZoneId zoneId = ZoneId.of ( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant ( instant , zoneId );

In zoneId: America/Montreal that is: 2015-11-08T00:17:05.213-05:00[America/Montreal]

Half-Open

In date-time work, we commonly use the Half-Open approach to defining a span of time. The beginning is inclusive while the ending in exclusive. Rather than try to determine the last split-second of the end of the week (or month), we get the first moment of the following week (or month). So a week runs from the first moment of Monday and goes up to but not including the first moment of the following Monday.

Let's the first day of the week, and last. The java.time framework includes a tool for that, the with method and the ChronoField enum.

By default, java.time uses the ISO 8601 standard. So Monday is the first day of the week (1) and Sunday is last (7).

ZonedDateTime firstOfWeek = zdt.with ( ChronoField.DAY_OF_WEEK , 1 ); // ISO 8601, Monday is first day of week.
ZonedDateTime firstOfNextWeek = firstOfWeek.plusWeeks ( 1 );

That week runs from: 2015-11-02T00:17:05.213-05:00[America/Montreal] to 2015-11-09T00:17:05.213-05:00[America/Montreal]

Oops! Look at the time-of-day on those values. We want the first moment of the day. The first moment of the day is not always 00:00:00.000 because of Daylight Saving Time (DST) or other anomalies. So we should let java.time make the adjustment on our behalf. To do that, we must go through the LocalDate class.

ZonedDateTime firstOfWeek = zdt.with ( ChronoField.DAY_OF_WEEK , 1 ); // ISO 8601, Monday is first day of week.
firstOfWeek = firstOfWeek.toLocalDate ().atStartOfDay ( zoneId );
ZonedDateTime firstOfNextWeek = firstOfWeek.plusWeeks ( 1 );

That week runs from: 2015-11-02T00:00-05:00[America/Montreal] to 2015-11-09T00:00-05:00[America/Montreal]

And same for the month.

ZonedDateTime firstOfMonth = zdt.with ( ChronoField.DAY_OF_MONTH , 1 );
firstOfMonth = firstOfMonth.toLocalDate ().atStartOfDay ( zoneId );
ZonedDateTime firstOfNextMonth = firstOfMonth.plusMonths ( 1 );

That month runs from: 2015-11-01T00:00-04:00[America/Montreal] to 2015-12-01T00:00-05:00[America/Montreal]

YearMonth

Another way to see if a pair of moments are in the same month is to check for the same YearMonth value.

For example, assuming thisZdt and thatZdt are both ZonedDateTime objects:

boolean inSameMonth = YearMonth.from( thisZdt ).equals( YearMonth.from( thatZdt ) ) ;

Milliseconds

I strongly recommend against doing your date-time work in milliseconds-from-epoch. That is indeed the way date-time classes tend to work internally, but we have the classes for a reason. Handling a count-from-epoch is clumsy as the values are not intelligible by humans so debugging and logging is difficult and error-prone. And, as we've already seen, different resolutions may be in play; old Java classes and Joda-Time library use milliseconds, while databases like Postgres use microseconds, and now java.time uses nanoseconds.

Would you handle text as bits, or do you let classes such as String, StringBuffer, and StringBuilder handle such details?

But if you insist, from a ZonedDateTime get an Instant, and from that get a milliseconds-count-from-epoch. But keep in mind this call can mean loss of data. Any microseconds or nanoseconds that you might have in your ZonedDateTime/Instant will be truncated (lost).

long millis = firstOfWeek.toInstant().toEpochMilli();  // Possible data loss.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

For me (using bootstrap), only thing that worked was setting display:absolute;z-index:1 on the last cell.

async and defer will download the file during HTML parsing. Both will not interrupt the parser.

• The script with async attribute will be executed once it is downloaded. While the script with defer attribute will be executed after completing the DOM parsing.

• The scripts loaded with async doesn't guarantee any order. While the scripts loaded with defer attribute maintains the order in which they appear on the DOM.

Use <script async> when the script does not rely on anything. when the script depends use <script defer>.

Best solution would be add the <script> at the bottom of the body. There will be no issue with blocking or rendering.

In WAMPServer 3 you dont do this in httpd.conf

Instead edit \wamp\bin\apache\apache{version}\conf\extra\httpd-vhost.conf and do the same chnage to the Virtual Host defined for localhost

WAMPServer 3 comes with a Virtual Host pre defined for localhost

Don't know who looks at your file, but if you open it in wordpad instead of notepad, the linebreaks will show correct. In case you're using a special file extension, associate it with wordpad and you're done with it. Or use any other more advanced text editor.

Try to check for existence:

IF NOT EXISTS (SELECT * FROM dbo.Employee WHERE ID = @SomeID)

    INSERT INTO dbo.Employee(Col1, ..., ColN)
    VALUES(Val1, .., ValN)

ELSE

    UPDATE dbo.Employee
    SET Col1 = Val1, Col2 = Val2, ...., ColN = ValN
    WHERE ID = @SomeID

You could easily wrap this into a stored procedure and just call that stored procedure from the outside (e.g. from a programming language like C# or whatever you're using).

Update: either you can just write this entire statement in one long string (doable - but not really very useful) - or you can wrap it into a stored procedure:

CREATE PROCEDURE dbo.InsertOrUpdateEmployee
       @ID INT,
       @Name VARCHAR(50),
       @ItemName VARCHAR(50),  
       @ItemCatName VARCHAR(50),
       @ItemQty DECIMAL(15,2)
AS BEGIN
    IF NOT EXISTS (SELECT * FROM dbo.Table1 WHERE ID = @ID)
       INSERT INTO dbo.Table1(ID, Name, ItemName, ItemCatName, ItemQty)
       VALUES(@ID, @Name, @ItemName, @ItemCatName, @ItemQty)
    ELSE
       UPDATE dbo.Table1
       SET Name = @Name,
           ItemName = @ItemName,
           ItemCatName = @ItemCatName,
           ItemQty = @ItemQty
       WHERE ID = @ID
END

and then just call that stored procedure from your ADO.NET code

Yes you can achive this by ajax post method. on server side you can use httphandler. So we are not using any server controls as per your requirement.

with ajax you can show the upload progress also.

you will have to read the file as a inputstream.

using (FileStream fs = File.Create("D:\\_Workarea\\" + fileName))

This was provided after installation of Sql Express 2019

Server=localhost\SQLEXPRESS;Database=master;Trusted_Connection=True;

So just use 'localhost\SQLEXPRESS' in server name and windows authentication worked for me.

Andrew Willem's solutions are not mobile device compatible.

Here's a modification of his second solution that works in Edge, IE, Opera, FF, Chrome, iOS Safari and mobile equivalents (that I could test):

Update 1: Removed "requestAnimationFrame" portion, as I agree it's not necessary:

var listener = function() {
  // do whatever
};

slider1.addEventListener("input", function() {
  listener();
  slider1.addEventListener("change", listener);
});
slider1.addEventListener("change", function() {
  listener();
  slider1.removeEventListener("input", listener);
}); 

Update 2: Response to Andrew's 2nd Jun 2016 updated answer:

Thanks, Andrew - that appears to work in every browser I could find (Win desktop: IE, Chrome, Opera, FF; Android Chrome, Opera and FF, iOS Safari).

Update 3: if ("oninput in slider) solution

The following appears to work across all the above browsers. (I cannot find the original source now.) I was using this, but it subsequently failed on IE and so I went looking for a different one, hence I ended up here.

if ("oninput" in slider1) {
    slider1.addEventListener("input", function () {
        // do whatever;
    }, false);
}

But before I checked your solution, I noticed this was working again in IE - perhaps there was some other conflict.

To make things shorter You can use this:

android.text.format.DateFormat.format("EEEE", date);

which will return day of the week as a String.

It sounds like you want to list all the metrics?

SELECT Criteria1, Criteria2, Metric1 As Metric
FROM Table1
UNION ALL
SELECT Criteria1, Criteria2, Metric2 As Metric
FROM Table2
ORDER BY 1, 2

If you only want one Criteria1+Criteria2 combination, group them:

SELECT Criteria1, Criteia2, SUM(Metric) AS Metric
FROM (
    SELECT Criteria1, Criteria2, Metric1 As Metric
    FROM Table1
    UNION ALL
    SELECT Criteria1, Criteria2, Metric2 As Metric
    FROM Table2
)
ORDER BY Criteria1, Criteria2

You can add a span to your html and css .

Here's an example from my code ...

HTML ( JSX ):

<input type="radio" name="AMPM" id="radiostyle1" value="AM" checked={this.state.AMPM==="AM"} onChange={this.handleChange}/>  
<label for="radiostyle1"><span></span> am  </label>

<input type="radio" name="AMPM" id="radiostyle2" value="PM" checked={this.state.AMPM==="PM"} onChange={this.handleChange}/>
<label for="radiostyle2"><span></span> pm  </label>

CSS to make standard radio button vanish on screen and superimpose custom button image:

input[type="radio"] {  
    opacity:0;                                      
}

input[type="radio"] + label {
    font-size:1em;
    text-transform: uppercase;
    color: white ;  
    cursor: pointer;
    margin:auto 15px auto auto;                    
}

input[type="radio"] + label span {
    display:inline-block;
    width:30px;
    height:10px;
    margin:1px 0px 0 -30px;                       
    cursor:pointer;
    border-radius: 20%;
}


input[type="radio"] + label span {
    background-color: #FFFFFF 
}


input[type="radio"]:checked + label span{
     background-color: #660006;  
}

Are you just looking to verify that the file is of a given extension? You can simplify what you are trying to do with something like this:

(.*?)\.(jpg|gif|doc|pdf)$

Then, when you call IsMatch() make sure to pass RegexOptions.IgnoreCase as your second parameter. There is no reason to have to list out the variations for casing.

Edit: As Dario mentions, this is not going to work for the RegularExpressionValidator, as it does not support casing options.

You can find your maven files here:

cd ~/.m2

Probably you need to copy settings.xml in your .m2 folder:

cp /usr/local/bin/apache-maven-2.2.1/conf/settings.xml .m2/

If no .m2 folder exists:

mkdir -p ~/.m2

Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.

<a href="Controller/ActionMethod">
    <input type="button" value="Click Me" />
</a>

Adding parameters:

<a href="Controller/ActionMethod?userName=ted">
    <input type="button" value="Click Me" />
</a>

Adding parameters from a non-enumerated Model:

<a href="Controller/[email protected]">
    <input type="button" value="Click Me" />
</a>

You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!

Here is an example of how you can do it in "classic" R graphics:

## generate some random data
carrotLengths <- rnorm(1000,15,5)
cucumberLengths <- rnorm(200,20,7)
## calculate the histograms - don't plot yet
histCarrot <- hist(carrotLengths,plot = FALSE)
histCucumber <- hist(cucumberLengths,plot = FALSE)
## calculate the range of the graph
xlim <- range(histCucumber$breaks,histCarrot$breaks)
ylim <- range(0,histCucumber$density,
              histCarrot$density)
## plot the first graph
plot(histCarrot,xlim = xlim, ylim = ylim,
     col = rgb(1,0,0,0.4),xlab = 'Lengths',
     freq = FALSE, ## relative, not absolute frequency
     main = 'Distribution of carrots and cucumbers')
## plot the second graph on top of this
opar <- par(new = FALSE)
plot(histCucumber,xlim = xlim, ylim = ylim,
     xaxt = 'n', yaxt = 'n', ## don't add axes
     col = rgb(0,0,1,0.4), add = TRUE,
     freq = FALSE) ## relative, not absolute frequency
## add a legend in the corner
legend('topleft',c('Carrots','Cucumbers'),
       fill = rgb(1:0,0,0:1,0.4), bty = 'n',
       border = NA)
par(opar)

The only issue with this is that it looks much better if the histogram breaks are aligned, which may have to be done manually (in the arguments passed to hist).

Alternate way using Zk-Client:

If you do not prefer to pass arguments to ./zookeeper-shell.sh and want to see the broker details from Zookeeper CLI, you need to install standalone Zookeeper (As traditional Kafka do not comes up with Jline JAR).

Once you install(unzip) the standalone Zookeeper,then:

• Run the Zookeeper CLI:
  $ zookeeper/bin/zkCli.sh -server localhost:2181 #Make sure your Broker is already running

• If it is successful, you can see the Zk client running as:

WATCHER::

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0]

• From here you can explore the broker details using various commands:

$ ls /brokers/ids # Gives the list of active brokers
$ ls /brokers/topics #Gives the list of topics
$ get /brokers/ids/0 #Gives more detailed information of the broker id '0'

I know this is an old question but I just found a solution which creates a user defined function using LTRIM and RTRIM. It does not handle double spaces in the middle of a string.

The solution is however straight forward:

User Defined Trim Function

I don't understand why Nick is using margin-left: 200px; instead off floating the other div to the left or right, I've just tweaked his markup, you can use float for both elements instead of using margin-left.

Demo

#main {
    margin: auto;
    width: 400px;
}

#sidebar    {
    width: 100px;
    min-height: 400px;
    background: red;
    float: left;
}

#page-wrap  {
    width: 300px;
    background: #0f0;
    min-height: 400px;
    float: left;
}

.clear:after {
    clear: both;
    display: table;
    content: "";
}

Also, I've used .clear:after which am calling on the parent element, just to self clear the parent.

Answer from italo is very good! However let me refine it a little:

function isEllipsisActive(e) {
   var tolerance = 2; // In px. Depends on the font you are using
   return e.offsetWidth + tolerance < e.scrollWidth;
}

Cross browser compatibility

If, in fact, you try the above code and use console.log to print out the values of e.offsetWidth and e.scrollWidth, you will notice, on IE, that, even when you have no text truncation, a value difference of 1px or 2px is experienced.

So, depending on the font size you use, allow a certain tolerance!

on OSX shell, this works for me (including 2 spaces in front of "red text"):

$ printf "\e[033;31m  red text\n"
$ echo "$(tput setaf 1)  red text"

I made this very simple function that works wonders:

function safeOrZero(route) {
  try {
    Function(`return (${route})`)();
  } catch (error) {
    return 0;
  }
  return Function(`return (${route})`)();
}

The route is whatever chain of values that can blow up. I use it for jQuery/cheerio and objects and such.

Examples 1: a simple object such as this const testObj = {items: [{ val: 'haya' }, { val: null }, { val: 'hum!' }];};.

But it could be a very large object that we haven't even made. So I pass it through:

let value1 = testobj.items[2].val;  // "hum!"
let value2 = testobj.items[3].val;  // Uncaught TypeError: Cannot read property 'val' of undefined

let svalue1 = safeOrZero(`testobj.items[2].val`)  // "hum!"
let svalue2 = safeOrZero(`testobj.items[3].val`)  // 0

Of course if you prefer you can use null or 'No value'... Whatever suit your needs.

Usually a DOM query or a jQuery selector may throw an error if it's not found. But using something like:

const bookLink = safeOrZero($('span.guidebook > a')[0].href);
if(bookLink){
  [...]
}

We use a script which checks if a running container is started with the latest image. We also use upstart init scripts for starting the docker image.

#!/usr/bin/env bash
set -e
BASE_IMAGE="registry"
REGISTRY="registry.hub.docker.com"
IMAGE="$REGISTRY/$BASE_IMAGE"
CID=$(docker ps | grep $IMAGE | awk '{print $1}')
docker pull $IMAGE

for im in $CID
do
    LATEST=`docker inspect --format "{{.Id}}" $IMAGE`
    RUNNING=`docker inspect --format "{{.Image}}" $im`
    NAME=`docker inspect --format '{{.Name}}' $im | sed "s/\///g"`
    echo "Latest:" $LATEST
    echo "Running:" $RUNNING
    if [ "$RUNNING" != "$LATEST" ];then
        echo "upgrading $NAME"
        stop docker-$NAME
        docker rm -f $NAME
        start docker-$NAME
    else
        echo "$NAME up to date"
    fi
done

And init looks like

docker run -t -i --name $NAME $im /bin/bash

Manually:

1. Add libs folder in your project(Where build.gradle is located). E.g. app
2. Move .jar into libs
3. Add implementation files('libs/<name>.jar') into build.gradle. It is the same as UI Add as library do

For me, all I had to do is add maxReceivedMessageSize="2147483647" to the client app.config. The server left untouched.

To summarize a bit from what people have been saying:

f=open('data.txt', 'w') # will make a new file or erase a file of that name if it is present
f=open('data.txt', 'r') # will open a file as read-only
f=open('data.txt', 'a') # will open a file for appending (appended data goes to the end of the file)

If you wish have something in place similar to a try/catch

with open('data.txt') as f:
    for line in f:
        print line

I think @movieyoda code is probably what you should use however

There are two main reasons why you can use an atomic boolean. First its mutable, you can pass it in as a reference and change the value that is a associated to the boolean itself, for example.

public final class MyThreadSafeClass{

    private AtomicBoolean myBoolean = new AtomicBoolean(false);
    private SomeThreadSafeObject someObject = new SomeThreadSafeObject();

    public boolean doSomething(){
         someObject.doSomeWork(myBoolean);
         return myBoolean.get(); //will return true
    }
}

and in the someObject class

public final class SomeThreadSafeObject{
    public void doSomeWork(AtomicBoolean b){
        b.set(true);
    }
}

More importantly though, its thread safe and can indicate to developers maintaining the class, that this variable is expected to be modified and read from multiple threads. If you do not use an AtomicBoolean you must synchronize the boolean variable you are using by declaring it volatile or synchronizing around the read and write of the field.

If your file is in the different package structure and you want to call it from a different package, then you can call it in that fashion:

Let's say you have following package structure in your python project:

in - com.my.func.DifferentFunction python file you have some function, like:

def add(arg1, arg2):
    return arg1 + arg2

def sub(arg1, arg2) :
    return arg1 - arg2

def mul(arg1, arg2) :
    return arg1 * arg2

And you want to call different functions from Example3.py, then following way you can do it:

Define import statement in Example3.py - file for import all function

from com.my.func.DifferentFunction import *

or define each function name which you want to import

from com.my.func.DifferentFunction import add, sub, mul

Then in Example3.py you can call function for execute:

num1 = 20
num2 = 10

print("\n add : ", add(num1,num2))
print("\n sub : ", sub(num1,num2))
print("\n mul : ", mul(num1,num2))

Output:

 add :  30

 sub :  10

 mul :  200

first off, to be a bit of a henpeck, its best NOT to use just the <background> tag. rather, use the proper, more specific, <background-image> tag.

the only way that i'm aware of to do such a thing is to build the padding into the image by extending the matte. since the empty pixels aren't stripped, you have your padding right there. so if you need a 10px border, create 10px of empty pixels all around your image. this is mui simple in Photoshop, Fireworks, GIMP, &c.

i'd also recommend trying out the PNG8 format instead of the dying GIF... much better.

there may be an alternate solution to your problem if we knew a bit more of how you're using it. :) it LOOKS like you're trying to add an accordion button. this would be best placed in the HTML because then you can target it with JavaScript/PHP; something you cannot do if it's in the background (at least not simply). in such a case, you can style the heck out of the image you currently have in CSS by using the following:

#hello img { padding: 10px; }

WR!

You don't need HttpServletResponse to set a header on the response. You can do it using javax.ws.rs.core.Response. Just make your method to return Response instead of entity:

return Response.ok(entity).header("Content-Disposition", "attachment; filename=\"" + fileName + "\"").build()

If you still want to use HttpServletResponse you can get it either injected to one of the class fields, or using property, or to method parameter:

@Path("/resource")
class MyResource {

  // one way to get HttpServletResponse
  @Context
  private HttpServletResponse anotherServletResponse;

  // another way
  Response myMethod(@Context HttpServletResponse servletResponse) {
      // ... code
  }
}

In this case you could use something like this:

User::where('this', '=', 1)
    ->whereNotNull('created_at')
    ->whereNotNull('updated_at')
    ->where(function($query){
        return $query
        ->whereNull('alias')
        ->orWhere('alias', '=', 'admin');
    });

It should supply you with a query like:

SELECT * FROM `user` 
WHERE `user`.`this` = 1 
    AND `user`.`created_at` IS NOT NULL 
    AND `user`.`updated_at` IS NOT NULL 
    AND (`alias` IS NULL OR `alias` = 'admin')

When it comes to a range of commits, cherry-picking is was not practical.

As mentioned below by Keith Kim, Git 1.7.2+ introduced the ability to cherry-pick a range of commits (but you still need to be aware of the consequence of cherry-picking for future merge)

git cherry-pick" learned to pick a range of commits
(e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git revert"; these do not support the nicer sequencing control "rebase [-i]" has, though.

damian comments and warns us:

In the "cherry-pick A..B" form, A should be older than B.
If they're the wrong order the command will silently fail.

If you want to pick the range B through D (including B) that would be B^..D (instead of B..D).
See "Git create branch from range of previous commits?" as an illustration.

As Jubobs mentions in the comments:

This assumes that B is not a root commit; you'll get an "unknown revision" error otherwise.

Note: as of Git 2.9.x/2.10 (Q3 2016), you can cherry-pick a range of commit directly on an orphan branch (empty head): see "How to make existing branch an orphan in git".

Original answer (January 2010)

A rebase --onto would be better, where you replay the given range of commit on top of your integration branch, as Charles Bailey described here.
(also, look for "Here is how you would transplant a topic branch based on one branch to another" in the git rebase man page, to see a practical example of git rebase --onto)

If your current branch is integration:

# Checkout a new temporary branch at the current location
git checkout -b tmp

# Move the integration branch to the head of the new patchset
git branch -f integration last_SHA-1_of_working_branch_range

# Rebase the patchset onto tmp, the old location of integration
git rebase --onto tmp first_SHA-1_of_working_branch_range~1 integration

That will replay everything between:

• after the parent of first_SHA-1_of_working_branch_range (hence the ~1): the first commit you want to replay
• up to "integration" (which points to the last commit you want to replay, from the working branch)

to "tmp" (which points to where integration was pointing before)

If there is any conflict when one of those commits is replayed:

• either solve it and run "git rebase --continue".
• or skip this patch, and instead run "git rebase --skip"
• or cancel the all thing with a "git rebase --abort" (and put back the integration branch on the tmp branch)

After that rebase --onto, integration will be back at the last commit of the integration branch (that is "tmp" branch + all the replayed commits)

With cherry-picking or rebase --onto, do not forget it has consequences on subsequent merges, as described here.

A pure "cherry-pick" solution is discussed here, and would involve something like:

If you want to use a patch approach then "git format-patch|git am" and "git cherry" are your options.
Currently, git cherry-pick accepts only a single commit, but if you want to pick the range B through D that would be B^..D in git lingo, so

git rev-list --reverse --topo-order B^..D | while read rev 
do 
  git cherry-pick $rev || break 
done 

But anyway, when you need to "replay" a range of commits, the word "replay" should push you to use the "rebase" feature of Git.

SOLUTIONS

1. Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
2. Paste the following line in CMakeCache.txt: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

Note the path to g++ depends on OS. I have used my fedora path obtained using which g++

Well you can:

• Check that the length is a multiple of 4 characters
• Check that every character is in the set A-Z, a-z, 0-9, +, / except for padding at the end which is 0, 1 or 2 '=' characters

If you're expecting that it will be base64, then you can probably just use whatever library is available on your platform to try to decode it to a byte array, throwing an exception if it's not valid base 64. That depends on your platform, of course.

There is another way of doing this with just JavaScript. All you have to do is toggle the visibility based on the current state of the DIV's visibility in CSS.

Example:

function toggleVideo() {
     var e = document.getElementById('video-over');

     if(e.style.visibility == 'visible') {
          e.style.visibility = 'hidden';
     } else if(e.style.visibility == 'hidden') {
          e.style.visibility = 'visible';
     }
}

If you don't want to save instances of the 2 button in the class code, follow this BETTER way (this is more clear and fast!!) :

public void buttonPress(View v) {
  switch (v.getId()) {
    case R.id.button_one:
        // do something
        break;
    case R.id.button_two:
        // do something else
        break;
    case R.id.button_three:
        // i'm lazy, do nothing
        break;
  }
}

This answer is based on an article that no longer exists:

Summary of article:

"Basically, WCF is a service layer that allows you to build applications that can communicate using a variety of communication mechanisms. With it, you can communicate using Peer to Peer, Named Pipes, Web Services and so on.

You can’t compare them because WCF is a framework for building interoperable applications. If you like, you can think of it as a SOA enabler. What does this mean?

Well, WCF conforms to something known as ABC, where A is the address of the service that you want to communicate with, B stands for the binding and C stands for the contract. This is important because it is possible to change the binding without necessarily changing the code. The contract is much more powerful because it forces the separation of the contract from the implementation. This means that the contract is defined in an interface, and there is a concrete implementation which is bound to by the consumer using the same idea of the contract. The datamodel is abstracted out."

... later ...

"should use WCF when we need to communicate with other communication technologies (e,.g. Peer to Peer, Named Pipes) rather than Web Service"

You can define foreign key by:

public class Parent
{
   public int Id { get; set; }
   public virtual ICollection<Child> Childs { get; set; }
}

public class Child
{
   public int Id { get; set; }
   // This will be recognized as FK by NavigationPropertyNameForeignKeyDiscoveryConvention
   public int ParentId { get; set; } 
   public virtual Parent Parent { get; set; }
}

Now ParentId is foreign key property and defines required relation between child and existing parent. Saving the child without exsiting parent will throw exception.

If your FK property name doesn't consists of the navigation property name and parent PK name you must either use ForeignKeyAttribute data annotation or fluent API to map the relation

Data annotation:

// The name of related navigation property
[ForeignKey("Parent")]
public int ParentId { get; set; }

Fluent API:

modelBuilder.Entity<Child>()
            .HasRequired(c => c.Parent)
            .WithMany(p => p.Childs)
            .HasForeignKey(c => c.ParentId);

Other types of constraints can be enforced by data annotations and model validation.

Edit:

You will get an exception if you don't set ParentId. It is required property (not nullable). If you just don't set it it will most probably try to send default value to the database. Default value is 0 so if you don't have customer with Id = 0 you will get an exception.

Working JSFIDDLE

If your form is like

<form action="" method="get" id="hidden-element-test">
      First name: <input type="text" name="fname"><br>
      Last name: <input type="text" name="lname"><br>
      <input type="submit" value="Submit">
</form> 
    <br><br>   
    <button id="add-input">Add hidden input</button>
    <button id="add-textarea">Add hidden textarea</button>

You can add hidden input and textarea to form like this

$(document).ready(function(){

    $("#add-input").on('click', function(){
        $('#hidden-element-test').prepend('<input type="hidden" name="ipaddress" value="192.168.1.201" />');
        alert('Hideen Input Added.');
    });

    $("#add-textarea").on('click', function(){
        $('#hidden-element-test').prepend('<textarea name="instructions" style="display:none;">this is a test textarea</textarea>');
        alert('Hideen Textarea Added.');
    });

});

Base64 instead of escaping special characters

I'll give you a very different but real example: I write javascript code to be run in a browser. HTML tags have ID values, but there are constraints on what characters are valid in an ID.

But I want my ID to losslessly refer to files in my file system. Files in reality can have all manner of weird and wonderful characters in them from exclamation marks, accented characters, tilde, even emoji! I cannot do this:

<div id="/path/to/my_strangely_named_file!@().jpg">
    <img src="http://myserver.com/path/to/my_strangely_named_file!@().jpg">
    Here's a pic I took in Moscow.
</div>

Suppose I want to run some code like this:

# ERROR
document.getElementById("/path/to/my_strangely_named_file!@().jpg");

I think this code will fail when executed.

With Base64 I can refer to something complicated without worrying about which language allows what special characters and which need escaping:

document.getElementById("18GerPD8fY4iTbNpC9hHNXNHyrDMampPLA");

Unlike using an MD5 or some other hashing function, you can reverse the encoding to find out what exactly the data was that actually useful.

I wish I knew about Base64 years ago. I would have avoided tearing my hair out with ‘encodeURIComponent’ and str.replace(‘\n’,’\\n’)

SSH transfer of text:

If you're trying to pass complex data over ssh (e.g. a dotfile so you can get your shell personalizations), good luck doing it without Base 64. This is how you would do it with base 64 (I know you can use SCP, but that would take multiple commands - which complicates key bindings for sshing into a server):

My 5 cents here, using form.elements which allows you to query each field by it's name, not only by iteration:

const form = document.querySelector('form[name="valform"]');
const ccValidation = form.elements['cctextbox'].value;
const ccType = form.elements['cardtype'].value;

We might confuse ourselves that a * b is a dot product.

But in fact, it is broadcast.

Dot Product : a.dot(b)

Broadcast:

The term broadcasting refers to how numpy treats arrays with different dimensions during arithmetic operations which lead to certain constraints, the smaller array is broadcast across the larger array so that they have compatible shapes.

(m,n) +-/* (1,n) ? (m,n) : the operation will be applied to m rows

Try this:

setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);

It will work.

It allows you to read from the standard input (mainly, the console). This SO question may helps you.

You might set location directly because it's slightly shorter. If you're trying to be terse, you can usually omit the window. too.

URL assignments to both location.href and location are defined to work in JavaScript 1.0, back in Netscape 2, and have been implemented in every browser since. So take your pick and use whichever you find clearest.

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

Siemano, get only php files from selected directory:

$dir    = '/home/zetdoa/ftp/domeny/MY_DOMAIN/projekty/project';
$files = scandir($dir, 1);


foreach($files as $file){
  $n = substr($file, -3);
  if($n == 'php'){
    echo $file.'<br />';
  }
}

Use attribute queryParamsHandling: 'merge' while changing the url.

this.router.navigate([], {
        queryParams: this.queryParams,
        queryParamsHandling: 'merge',
        replaceUrl: true,
});

Can you show code which you use for setting date object? Anyway< you can use this code for intialisation of date:

new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").parse("2011-01-01 00:00:00")

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

1. $page='one' should occur before you require_once() not after. After is too late- the code has already been required, and $nav has already been defined.

2. You should use include('header.php'); and include('footer.php'); instead of setting a $nav variable early on. That increases flexibility.

3. Make more functions. Something like this really makes things easier to follow:

   function maybe($x,$y){return $x?$y:'';}
   function aclass($k){return " class=\"$k\" "; }
   

   then you can write your "condition" like this:

   <a href="..." <?= maybe($page=='one',aclass('active')) ?>> ....
   

only css, quite simple I find it:

.checkmark {_x000D_
      display: inline-block;_x000D_
      transform: rotate(45deg);_x000D_
      height: 25px;_x000D_
      width: 12px;_x000D_
      margin-left: 60%; _x000D_
      border-bottom: 7px solid #78b13f;_x000D_
      border-right: 7px solid #78b13f;_x000D_
    }

<div class="checkmark"></div>

To answer the original posters question.... to 'decrypt' the password, you have to do what a password cracker would do.

In other words, you'd run a program to read from a large list of potential passwords (a password dictionary) and you'd hash each one using bcrypt and the salt and complexity from the password you're trying to decipher. If you're lucky you'll find a match, but if the password is a strong one then you likely won't find a match.

Bcrypt has the added security characteristic of being a slow hash. If your password had been hashed with md5 (terrible choice) then you'd be able to check billions of passwords per second, but since it's hashed using bcrypt you will be able to check far fewer per second.

The fact that bcrypt is slow to hash and salted is what makes it a good choice for password storage even today. That being said I believe NIST recommends the PBKDF2 for password hashing.

Yes, it is absolutely no problem. You could even have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.

In fact, i have such a setup myself.

throw new RuntimeException(msg);

You need the new in there. It's creating an instance and throwing it, not calling a method.

Using Apache Commons IO.

import org.apache.commons.io.FileUtils;

//...

String contents = FileUtils.readFileToString(new File("/path/to/the/file"), "UTF-8")

You can see de javadoc for the method for details.

You cannot instantiate an abstract class, Jackson neither. You should give Jackson information on how to instantiate MyAbstractClass with a concrete type.

See this answer on stackoverflow: Jackson JSON library: how to instantiate a class that contains abstract fields

And maybe also see Jackson Polymorphic Deserialization

You can either define the right default value into the model you want to edit with this form or you can specify an empty_data option so your code become:

$form = $this
    ->createFormBuilder($breed)
    ->add(
        'species',
        'entity',
        array(
            'class'         => 'BFPEduBundle:Item',
            'property'      => 'name',
            'empty_data'    => 123,
            'query_builder' => function(ItemRepository $er) {
                return $er
                    ->createQueryBuilder('i')
                    ->where("i.type = 'species'")
                    ->orderBy('i.name', 'ASC')
                ;
            }
        )
    )
    ->add('breed', 'text', array('required'=>true))
    ->add('size', 'textarea', array('required' => false))
    ->getForm()
;

Exactly what it sounds like, assuming you're used to the abbreviated way in which C and UNIX assigns words, it duplicates strings :-)

Keeping in mind it's actually not part of the ISO C standard itself^(a) (it's a POSIX thing), it's effectively doing the same as the following code:

char *strdup(const char *src) {
    char *dst = malloc(strlen (src) + 1);  // Space for length plus nul
    if (dst == NULL) return NULL;          // No memory
    strcpy(dst, src);                      // Copy the characters
    return dst;                            // Return the new string
}

In other words:

1. It tries to allocate enough memory to hold the old string (plus a '\0' character to mark the end of the string).

2. If the allocation failed, it sets errno to ENOMEM and returns NULL immediately. Setting of errno to ENOMEM is something malloc does in POSIX so we don't need to explicitly do it in our strdup. If you're not POSIX compliant, ISO C doesn't actually mandate the existence of ENOMEM so I haven't included that here^(b).

3. Otherwise the allocation worked so we copy the old string to the new string^(c) and return the new address (which the caller is responsible for freeing at some point).

Keep in mind that's the conceptual definition. Any library writer worth their salary may have provided heavily optimised code targeting the particular processor being used.

^(a) However, functions starting with str and a lower case letter are reserved by the standard for future directions. From C11 7.1.3 Reserved identifiers:

Each header declares or defines all identifiers listed in its associated sub-clause, and *optionally declares or defines identifiers listed in its associated future library directions sub-clause.**

The future directions for string.h can be found in C11 7.31.13 String handling <string.h>:

Function names that begin with str, mem, or wcs and a lowercase letter may be added to the declarations in the <string.h> header.

So you should probably call it something else if you want to be safe.

^(b) The change would basically be replacing if (d == NULL) return NULL; with:

if (d == NULL) {
    errno = ENOMEM;
    return NULL;
}

^(c) Note that I use strcpy for that since that clearly shows the intent. In some implementations, it may be faster (since you already know the length) to use memcpy, as they may allow for transferring the data in larger chunks, or in parallel. Or it may not :-) Optimisation mantra #1: "measure, don't guess".

In any case, should you decide to go that route, you would do something like:

char *strdup(const char *src) {
    size_t len = strlen(src) + 1;       // String plus '\0'
    char *dst = malloc(len);            // Allocate space
    if (dst == NULL) return NULL;       // No memory
    memcpy (dst, src, len);             // Copy the block
    return dst;                         // Return the new string
}

This prints it in the console:

echo %cd%

or paste this command in CMD, then you'll have pwd:

(echo @echo off
echo echo ^%cd^%) > C:\WINDOWS\pwd.bat

I agree with @Cthulhu answer. In your code you can reset your Scanner object (in).

in.reset();

This will reset your in object at the first line of your file.

This may be a common problem for new users of Matplotlib to draw vertical and horizontal lines. In order to understand this problem, you should be aware that different coordinate systems exist in Matplotlib.

The method axhline and axvline are used to draw lines at the axes coordinate. In this coordinate system, coordinate for the bottom left point is (0,0), while the coordinate for the top right point is (1,1), regardless of the data range of your plot. Both the parameter xmin and xmax are in the range [0,1].

On the other hand, method hlines and vlines are used to draw lines at the data coordinate. The range for xmin and xmax are the in the range of data limit of x axis.

Let's take a concrete example,

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 5, 100)
y = np.sin(x)

fig, ax = plt.subplots()

ax.plot(x, y)
ax.axhline(y=0.5, xmin=0.0, xmax=1.0, color='r')
ax.hlines(y=0.6, xmin=0.0, xmax=1.0, color='b')

plt.show()

It will produce the following plot:

The value for xmin and xmax are the same for the axhline and hlines method. But the length of produced line is different.

I'm not sure whether you think about:

select * from friend f
where not exists (
    select 1 from likes l where f.id1 = l.id and f.id2 = l.id2
)

it works only if id1 is related with id1 and id2 with id2 not both.

System.setProperty("javax.net.ssl.trustStore", path_to_your_jks_file);

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

I am not sure if something has changed, but I just tried the other answers regarding entries in "eclipse.ini" for Eclipse Galileo SR2 (Windows XP SR3) and none worked. Java is jdk1.6.0_18 and is the default Windows install. Things improved when I dropped "\javaw.exe" from the path.

Also, I can't thank enough the mention that -vm needs to be first line in the ini file. I believe that really helped me out.

Thus my eclipse.ini file starts with:

-vm
C:\Program Files\Java\jdk1.6.0_18\bin

FYI, my particular need to specify launching Eclipse with a JDK arose from my wanting to work with the m2eclipse plugin.

well, you can do it a lot of ways... one of them is to create a HttpRequest. I would advise you against calling your own webapi from your own MVC (the idea is redundant...) but, here's a end to end tutorial.

That's the principle of a Pseudo-RNG. The numbers are not really random. They are generated using a deterministic algorithm, but depending on the seed, the sequence of generated numbers vary. Since you always use the same seed, you always get the same sequence.

I believe Twitter Bootstrap has a class called clearfix that you can use to clear the floating.

<ul class="nav nav-tabs span2 clearfix">

Methods can only declare local variables. That is why the compiler reports an error when you try to declare it as public.

In the case of local variables you can not use any kind of accessor (public, protected or private).

You should also know what the static keyword means. In method checkYourself, you use the Integer array locations.

The static keyword distinct the elements that are accessible with object creation. Therefore they are not part of the object itself.

public class Test { //Capitalized name for classes are used in Java
   private final init[] locations; //key final mean that, is must be assigned before object is constructed and can not be changed later. 

   public Test(int[] locations) {
      this.locations = locations;//To access to class member, when method argument has the same name use `this` key word. 
   }

   public boolean checkYourSelf(int value) { //This method is accessed only from a object.
      for(int location : locations) {
         if(location == value) {
            return true; //When you use key word return insied of loop you exit from it. In this case you exit also from whole method.
         }
      }
      return false; //Method should be simple and perform one task. So you can get more flexibility. 
   }
   public static int[] locations = {1,2,3};//This is static array that is not part of object, but can be used in it. 

   public static void main(String[] args) { //This is declaration of public method that is not part of create object. It can be accessed from every place.
      Test test = new Test(Test.locations); //We declare variable test, and create new instance (object) of class Test.  
      String result;
      if(test.checkYourSelf(2)) {//We moved outside the string
        result = "Hurray";        
      } else {
        result = "Try again"
      }
      System.out.println(result); //We have only one place where write is done. Easy to change in future.
   } 
}

Here's my take if you want to try using multiprocesses to process each row of numpy array,

from multiprocessing import Pool
import numpy as np

def my_function(x):
    pass     # do something and return something

if __name__ == '__main__':    
    X = np.arange(6).reshape((3,2))
    pool = Pool(processes = 4)
    results = pool.map(my_function, map(lambda x: x, X))
    pool.close()
    pool.join()

pool.map take in a function and an iterable.
I used 'map' function to create an iterator over each rows of the array.
Maybe there's a better to create the iterable though.

>>> numpy.array([[1, 2], [3, 4]]) 
array([[1, 2], [3, 4]])

Or use diff method of numpy:

import numpy as np
def allthesame(l):
    return np.unique(l).shape[0]<=1

And to call:

print(allthesame([1,1,1]))

Output:

True

Seems everyone has difference experiences from this and therfore solutions as well :) This is my "story".

My thing came from a validate.php file fetched with ajax. The output was meant to be :

$response['status'] = $status;
$response['message'] = $message;
$response['param'] = $param;

echo json_encode($response);

And the error that cause the "Unexpected token <" error was simply that in some cases $message hadn't been declared (but only $status and $param). So, added this in the beginning of the code.

$message = ''; // Default value, in case it doesn't get set later on.

So I guess, those "little things" may in this scenario big of quite importance. So be sure to really check your code and making it bulletproof.

I may be a little late for this, but I would recommend Aptana Studio 3.x . Its a based on eclipse and has everything ready-to-go for python. It has very good support for DJango, HTML5 and JQuery. For me its a perfect web-development tool. I do HTML5 and Android development too, this way I do not need to keep switching different IDE's. It my all-in-one solution.

Note: you need a good amount of RAM for this to be snazzy !! 4+ GB is awesome !!

The error message is pretty straightforward: getComputedStyle expects an Element as its first argument, and something else was passed to it.

If what you are really asking for is help with debugging your skin, you should make more of an effort to isolate the error.

Visual Studio reads NuGet.Config files from the solution root. Try moving it there instead of placing it in the same folder as the project.

You can also place the file at %appdata%\NuGet\NuGet.Config and it will be used everywhere.

The ...For extension methods on the HtmlHelper (e.g., DisplayFor, TextBoxFor, ElementFor, etc...) take a property and nothing else. If you don't have a property, use the non-For method (e.g., Display, TextBox, Element, etc...).

The ...For extension methods provides a way of simplifying postback by naming the control after the property. This is why it takes an expression and not simply a value. If you are not interested in this postback facilitation then do not use the ...For methods at all.

Note: You should not be doing things like calling ToString inside the view. This should be done inside the view model. I realize that a lot of demo projects put domain objects straight into the view. In my experience, this rarely works because it assumes that you do not want any formatting on the data in the domain entity. Best practice is to create a view model that wraps the entity into something that can be directly consumed by the view. Most of the properties in this view model should be strings that are already formatted or data for which you have element or display templates created.

The error is happening because you (or whoever designed this table) have a bunch of dates in VARCHAR. Why are you (or whoever designed this table) storing dates as strings? Do you (or whoever designed this table) also store salary and prices and distances as strings?

To find the values that are causing issues (so you (or whoever designed this table) can fix them):

SELECT GRADUATION_DATE FROM mydb
  WHERE ISDATE(GRADUATION_DATE) = 0;

Bet you have at least one row. Fix those values, and then FIX THE TABLE. Or ask whoever designed the table to FIX THE TABLE. Really nicely.

ALTER TABLE mydb ALTER COLUMN GRADUATION_DATE DATE;

Now you don't have to worry about the formatting - you can always format as YYYYMMDD or YYYY-MM-DD on the client, or using CONVERT in SQL. When you have a valid date as a string literal, you can use:

SELECT CONVERT(CHAR(10), '20120101', 120);

...but this is better done on the client (if at all).

There's a popular term - garbage in, garbage out. You're never going to be able to convert to a date (never mind convert to a string in a specific format) if your data type choice (or the data type choice of whoever designed the table) inherently allows garbage into your table. Please fix it. Or ask whoever designed the table (again, really nicely) to fix it.

Provide a format string:

date +"%H:%M"

Running man date will give all the format options

%a     locale's abbreviated weekday name (e.g., Sun)

It will help you in linked list.

If you're using .NET Core 3.0, you can use System.Text.Json (which is now built-in) to deserialize JSON.

The first step is to create classes to model the JSON. There are many tools which can help with this, and some of the answers here list them.

Some options are http://json2csharp.com, http://app.quicktype.io, or use Visual Studio (menu Edit → Paste Special → Paste JSON as classes).

public class Person
{
    public string Id { get; set; }
    public string Name { get; set; }
}

public class Response
{
    public List<Person> Data { get; set; }
}

Then you can deserialize using:

var people = JsonSerializer.Deserialize<Response>(json);

If you need to add settings, such as camelCase handling, then pass serializer settings into the deserializer like this:

var options = new JsonSerializerOptions() { PropertyNamingPolicy = JsonNamingPolicy.CamelCase };
var person = JsonSerializer.Deserialize<Response>(json, options);

The other answers are not working for me - they may be outdated. This is what I used as my solution for auto setting an attribute:

/**
 * The "booting" method of the model.
 *
 * @return void
 */
protected static function boot()
{
    parent::boot();

    // auto-sets values on creation
    static::creating(function ($query) {
        $query->is_voicemail = $query->is_voicemail ?? true;
    });
}

For Windows 10 & Python 3.5.1 users:

While installing Python on Windows 10, please don't forget to check the "Add to cmd prompt" option before hitting the "Install". This would help in easily access python from cmd.

If the option was not checked, then please use Set Path in cmd to see if it is available as executables or not. If not, Navigate to Start >> Control Panel >> System and Security >> System >> Advanced System Settings >> Advanced >> Environment Variables.. >> Select PATH from System Variables and Edit it. Then copy "C:\Python35\cmd" in the new line. After this please add .PY to PATHEXT in the same procedure.

Also please check if Start >> Control Panel >> System and Security >> System >> Advanced System Settings >> Advanced >> Environment Variables.. >> User variables from Username >> PATH is containing these two lines - "C:\Users\Username\AppData\Local\Programs\Python\Python35-32\Scripts\" & "C:\Users\Username\AppData\Local\Programs\Python\Python35-32\". Else please add them manually.

According to a react developer, you dont need the namespace xmlns. If you need the attribute xlink:href you can use xlinkHref from react 0.14

Example

Icon = (props) => {
  return <svg className="icon">
    <use xlinkHref={ '#' + props.name }></use>
  </svg>;
}
