Getting the Phone Number, IMEI, and SIM Card ID

TelephonyManager tm = (TelephonyManager) 
            getSystemService(Context.TELEPHONY_SERVICE);        

For SIM card, use the getSimSerialNumber()

    //---get the SIM card ID---
    String simID = tm.getSimSerialNumber();
    if (simID != null)
        Toast.makeText(this, "SIM card ID: " + simID, 
        Toast.LENGTH_LONG).show();

Phone number of your phone, use the getLine1Number() (some device's dont return the phone number)

    //---get the phone number---
    String telNumber = tm.getLine1Number();
    if (telNumber != null)        
        Toast.makeText(this, "Phone number: " + telNumber, 
        Toast.LENGTH_LONG).show();

IMEI number of the phone, use the getDeviceId()

    //---get the IMEI number---
    String IMEI = tm.getDeviceId();
    if (IMEI != null)        
        Toast.makeText(this, "IMEI number: " + IMEI, 
        Toast.LENGTH_LONG).show();

Permissions needed

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Property hibernate.allow_refresh_detached_entity did the trick for me. But it is a general rule, so it is not very suitable if you want to do it only in some cases. I hope it helps.

Tested on Hibernate 5.4.9

Kotlin

val dialogView = LayoutInflater.from(requireContext()).inflate(R.layout.dialog_userinput, null)
        val dialogBuilder = MaterialAlertDialogBuilder(requireContext(), R.style.AlertDialogTheme)
   
        dialogBuilder.setView(dialogView)
        dialogBuilder.setCancelable(false)
        dialogBuilder.setPositiveButton("send",null)
        dialogBuilder.setNegativeButton("cancel") { dialog,_ ->
        dialog.dismiss()
        }


        val alertDialog = dialogBuilder.create()
        alertDialog.show()

        val positiveButton = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE)
        positiveButton.setOnClickListener {
            val myInputText = dialogView.etxt_userinput.text.toString().trim()
            if(myInputText.isNotEmpty()){
             //Do something
            }else{
                //Prompt error
                dialogView.etxt_userinput.error = "Please fill this"
            }
        }

We just create an AlertDialog with the dialogBuilder and then just set the positive button as we want

As I had imported my project from a "git clone", I had to select File->Import-> Git->Project from git -> Existing local repository

In android 2.2 you could do the following.

Create an xml drawable such as /res/drawable/textlines.xml and assign this as a TextView's background property.

<TextView
android:text="My text with lines above and below"
android:background="@drawable/textlines"
/>

/res/drawable/textlines.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
      <shape 
        android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FF000000" />
            <solid android:color="#FFDDDDDD" />

        </shape>
   </item>

   <item android:top="1dp" android:bottom="1dp"> 
      <shape 
        android:shape="rectangle">
            <stroke android:width="1dp" android:color="#FFDDDDDD" />
            <solid android:color="#00000000" />
        </shape>
   </item>

</layer-list>

The down side to this is that you have to specify an opaque background colour, as transparencies won't work. (At least i thought they did but i was mistaken). In the above example you can see that the solid colour of the first shape #FFdddddd is copied in the 2nd shapes stroke colour.

That's an old question, I know. But, according to me, it is missing proper answer.

The actual / optimal workflow here would be to incorporate SVN's post-commit hook so it triggers Jenkins job after the actual commit is issued only, not in any other case. This way you avoid unneeded polls on your SCM system.

You may find the following links interesting:

• Jenkins Wiki's post-commit hook description on Subversion Plugin's doc-site. Here you find documented example of the script you are interested in.
• Hook-scripts contrib directory in the source of official Apache Foundation's Subversion's source control repository.
• Similar question on StackOverflow.

In case of my setup in the corp's SVN server, I utilize the following (censored) script as a post-commit hook on the subversion server side:

#!/bin/sh

# POST-COMMIT HOOK

REPOS="$1"
REV="$2"
#TXN_NAME="$3"
LOGFILE=/var/log/xxx/svn/xxx.post-commit.log

MSG=$(svnlook pg --revprop $REPOS svn:log -r$REV)
JENK="http://jenkins.xxx.com:8080/job/xxx/job/xxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"
JENKtest="http://jenkins.xxx.com:8080/view/all/job/xxx/job/xxxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"

echo post-commit $* >> $LOGFILE 2>&1

# trigger Jenkins job - xxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx/xxx/Source"
if test 0 -eq $? ; then
        echo $(date) - $REPOS - $REV: >> $LOGFILE
        svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx/xxx/Source" >> $LOGFILE 2>&1
        echo logmsg: $MSG >> $LOGFILE 2>&1
        echo curl -qs $JENK >> $LOGFILE 2>&1
        curl -qs $JENK >> $LOGFILE 2>&1
        echo -------- >> $LOGFILE
fi

# trigger Jenkins job - xxxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx_TEST"
if test 0 -eq $? ; then
        echo $(date) - $REPOS - $REV: >> $LOGFILE
        svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx_TEST" >> $LOGFILE 2>&1
        echo logmsg: $MSG >> $LOGFILE 2>&1
        echo curl -qs $JENKtest >> $LOGFILE 2>&1
        curl -qs $JENKtest >> $LOGFILE 2>&1
        echo -------- >> $LOGFILE
fi

exit 0

you can do it by two simple point and change in your code

1.In your xml in anim folder of your project, Set the fade in and fade out duration time not equal

2.In you java class before the start of fade out animation, set second imageView visibility Gone then after fade out animation started set second imageView visibility which you want to fade in visible

fadeout.xml

<alpha
    android:duration="4000"
    android:fromAlpha="1.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="0.0" />

fadein.xml

<alpha
    android:duration="6000"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="1.0" />

In you java class

Animation animFadeOut = AnimationUtils.loadAnimation(this, R.anim.fade_out);
    ImageView iv = (ImageView) findViewById(R.id.imageView1);
    ImageView iv2 = (ImageView) findViewById(R.id.imageView2);
    iv.setVisibility(View.VISIBLE);
    iv2.setVisibility(View.GONE);
    animFadeOut.reset();
    iv.clearAnimation();
    iv.startAnimation(animFadeOut);

    Animation animFadeIn = AnimationUtils.loadAnimation(this, R.anim.fade_in);
    iv2.setVisibility(View.VISIBLE);
    animFadeIn.reset();
    iv2.clearAnimation();
    iv2.startAnimation(animFadeIn);

write query with named parameter, use simple ListPreparedStatementSetter with all parameters in sequence. Just add below snippet to convert the query in traditional form based to available parameters,

ParsedSql parsedSql = NamedParameterUtils.parseSqlStatement(namedSql);

List<Integer> parameters = new ArrayList<Integer>();
for (A a : paramBeans)
    parameters.add(a.getId());

MapSqlParameterSource parameterSource = new MapSqlParameterSource();
parameterSource.addValue("placeholder1", parameters);
// create SQL with ?'s
String sql = NamedParameterUtils.substituteNamedParameters(parsedSql, parameterSource);     
return sql;

Two nitpicks. (1) Best not to use string literals for column alias - that is deprecated. (2) Just use style 120 to get the same value.

    CASE 
      WHEN CreatedDate = '19000101' THEN '' 
      WHEN CreatedDate = '18000101' THEN '' 
      ELSE Convert(varchar(19), CreatedDate, 120)
    END AS [Created Date]

I'll just update the code to contain the changes, and comment it to so that you can see what's going on clearly...

<?php   
include("templates/header.htm");   

// Set the default name 
$action = 'index'; 
// Specify some disallowed paths 
$disallowed_paths = array('header', 'footer'); 
if (!empty($_GET['action'])) { 
    $tmp_action = basename($_GET['action']); 
    // If it's not a disallowed path, and if the file exists, update $action 
    if (!in_array($tmp_action, $disallowed_paths) && file_exists("templates/{$tmp_action}.htm")) 
        $action = $tmp_action; 
} 
// Include $action 
include("templates/$action.htm"); 

include("templates/footer.htm");

Unlike a list or a dictionary, a generator can be infinite. Doing this wouldn't work:

def gen():
    x = 0
    while True:
        yield x
        x += 1
g1 = gen()
list(g1)   # never ends

Also, reading a generator changes it, so there's not a perfect way to view it. To see a sample of the generator's output, you could do

g1 = gen()
[g1.next() for i in range(10)]

You may need an extra "/"

If date in string format convert it to date format for each object :

String argmodifiledDate = "2014-04-06 22:26:15";
SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
            try
            {
                this.modifiledDate = format.parse(argmodifiledDate);
            }
            catch (ParseException e)
            {

                e.printStackTrace();
            }

Then sort the arraylist in descending order :

ArrayList<Document> lstDocument= this.objDocument.getArlstDocuments();
        Collections.sort(lstDocument, new Comparator<Document>() {
              public int compare(Document o1, Document o2) {
                  if (o1.getModifiledDate() == null || o2.getModifiledDate() == null)
                    return 0;     
                  return o2.getModifiledDate().compareTo(o1.getModifiledDate());
              }
            });

For me it happened because I had 2 versions of python installed - python 27 and python 3.3. Both these folder had path variable set, and hence there was this issue. To fix, this, I moved python27 to temp folder, as I was ok with python 3.3. So do check environment variables like PATH,PYTHONHOME as it may be a issue. Thanks.

read reads until it finds a newline character or the end of file, and returns a non-zero exit code if it encounters an end-of-file. So it's quite possible for it to both read a line and return a non-zero exit code.

Consequently, the following code is not safe if the input might not be terminated by a newline:

while read LINE; do
  # do something with LINE
done

because the body of the while won't be executed on the last line.

Technically speaking, a file not terminated with a newline is not a text file, and text tools may fail in odd ways on such a file. However, I'm always reluctant to fall back on that explanation.

One way to solve the problem is to test if what was read is non-empty (-n):

while read -r LINE || [[ -n $LINE ]]; do
  # do something with LINE
done

Other solutions include using mapfile to read the file into an array, piping the file through some utility which is guaranteed to terminate the last line properly (grep ., for example, if you don't want to deal with blank lines), or doing the iterative processing with a tool like awk (which is usually my preference).

Note that -r is almost certainly needed in the read builtin; it causes read to not reinterpret \-sequences in the input.

The key-value pair can take advanced inputs.

Ex.

For every field that has choices set, the object will have a get_FOO_display() method, where FOO is the name of the field. This method returns the “human-readable” value of the field.

In Views

person = Person.objects.filter(to_be_listed=True)
context['gender'] = person.get_gender_display()

In Template

{{ person.get_gender_display }}

Documentation of get_FOO_display()

PDB is an abbreviation for Program Data Base. As the name suggests, it is a repository (persistent storage such as databases) to maintain information required to run your program in debug mode. It contains many important relevant information required while you debug your code (in Visual Studio), for e.g. at what points you have inserted break points where you expect the debugger to break in Visual Studio.

This is the reason why many times Visual Studio fails to hit the break points if you remove the *.pdb files from your debug folders. Visual Studio debugger is also able to tell you the precise line number of code file at which an exception occurred in a stack trace with the help of *.pdb files. So effectively pdb files are really a boon to developers while debugging a program.

Generally it is not recommended to exclude the generation of *.pdb files. From production release stand-point what you should be doing is create the pdb files but don't ship them to customer site in product installer. Preserve all the generated PDB files on to a symbol server from where it can be used/referenced in future if required. Specially for cases when you debug issues like process crash. When you start analysing the crash dump files and if your original *.pdb files created during the build process are not preserved then Visual Studio will not be able to make out the exact line of code which is causing crash.

If you still want to disable generation of *.pdb files altogether for any release then go to properties of the project -> Build Tab -> Click on Advanced button -> Choose none from "Debug Info" drop-down box -> press OK as shown in the snapshot below.

Note: This setting will have to be done separately for "Debug" and "Release" build configurations.

One of the aspects of .NET I like the most are generics. Even if you write procedural code in F#, you will still benefit from type inference. It makes writing generic code easy.

In C#, you write concrete code by default, and you have to put in some extra work to write generic code.

In F#, you write generic code by default. After spending over a year of programming in both F# and C#, I find that library code I write in F# is both more concise and more generic than the code I write in C#, and is therefore also more reusable. I miss many opportunities to write generic code in C#, probably because I'm blinded by the mandatory type annotations.

There are however situations where using C# is preferable, depending on one's taste and programming style.

• C# does not impose an order of declaration among types, and it's not sensitive to the order in which files are compiled.
• C# has some implicit conversions that F# cannot afford because of type inference.

You can try this:

template<typename T>
inline const char* getTypeName() {
  return typeid(T).name();
}

#define DEFINE_TYPE_NAME(type, type_name)  \
  template<>                               \
  inline const char* getTypeName<type>() { \
    return type_name;                      \
  }

DEFINE_TYPE_NAME(int, "int")
DEFINE_TYPE_NAME(float, "float")
DEFINE_TYPE_NAME(double, "double")
DEFINE_TYPE_NAME(std::string, "string")
DEFINE_TYPE_NAME(bool, "bool")
DEFINE_TYPE_NAME(uint32_t, "uint")
DEFINE_TYPE_NAME(uint64_t, "uint")
// add your custom types' definitions

And call it like that:

void main() {
 std::cout << getTypeName<int>();
}

If you are using PHP's password_hash() with the PASSWORD_DEFAULT algorithm to generate the bcrypt hash (which I would assume is a large percentage of people reading this question) be sure to keep in mind that in the future password_hash() might use a different algorithm as the default and this could therefore affect the length of the hash (but it may not necessarily be longer).

From the manual page:

Note that this constant is designed to change over time as new and stronger algorithms are added to PHP. For that reason, the length of the result from using this identifier can change over time. Therefore, it is recommended to store the result in a database column that can expand beyond 60 characters (255 characters would be a good choice).

Using bcrypt, even if you have 1 billion users (i.e. you're currently competing with facebook) to store 255 byte password hashes it would only ~255 GB of data - about the size of a smallish SSD hard drive. It is extremely unlikely that storing the password hash is going to be the bottleneck in your application. However in the off chance that storage space really is an issue for some reason, you can use PASSWORD_BCRYPT to force password_hash() to use bcrypt, even if that's not the default. Just be sure to stay informed about any vulnerabilities found in bcrypt and review the release notes every time a new PHP version is released. If the default algorithm is ever changed it would be good to review why and make an informed decision whether to use the new algorithm or not.

Bydefault lazy loading is true.Lazy loading means when the select query is executed it will not hit the database. It will wait for getter function i.e when we required then ,it will fetch from the datbase. for example: You are a parent who has a kid with a lot of toys. But the current issue is whenever you call him (we assume you have a boy), he comes to you with all his toys as well. Now this is an issue since you do not want him carrying around his toys all the time. So being the rationale parent, you go right ahead and define the toys of the child as LAZY. Now whenever you call him, he just comes to you without his toys.

setBounds is used to define the bounding rectangle of a component. This includes it's position and size.

The is used in a number of places within the framework.

• It is used by the layout manager's to define the position and size of a component within it's parent container.
• It is used by the paint sub system to define clipping bounds when painting the component.

For the most part, you should never call it. Instead, you should use appropriate layout managers and let them determine the best way to provide information to this method.

You might want to give a look at this simple Javascript method to be invoked when clicking on a link to make a panel/div expande or collapse.

<script language="javascript"> 
function toggle(elementId) {
    var ele = document.getElementById(elementId);
    if(ele.style.display == "block") {
            ele.style.display = "none";
    }
    else {
        ele.style.display = "block";
    }
} 
</script>

You can pass the div ID and it will toggle between display 'none' or 'block'.

Original source on snip2code - How to collapse a div in html

Just to elaborate on what others have said, multiple CSS classes are combined in a single string, delimited by spaces. Thus, if you wanted to hard-code it, it would simply look like this:

<div class="someClass otherClass yetAnotherClass">
      <img ... id="image1" name="image1" />
</div>

From there you can easily derive the javascript necessary to add a new class... just append a space followed by the new class to the element's className property. Knowing this, you can also write a function to remove a class later should the need arise.

Using Commons Lang (to convert) + Collections (to min/max)

import java.util.Arrays;
import java.util.Collections;

import org.apache.commons.lang.ArrayUtils;

public class MinMaxValue {

    public static void main(String[] args) {
        char[] a = {'3', '5', '1', '4', '2'};

        List b = Arrays.asList(ArrayUtils.toObject(a));

        System.out.println(Collections.min(b));
        System.out.println(Collections.max(b));
   }
}

Note that Arrays.asList() wraps the underlying array, so it should not be too memory intensive and it should not perform a copy on the elements of the array.

This worked for me...

<asp:RadioButtonList runat="server" ID="Intent">
  <asp:ListItem Value="Confirm">Yes!</asp:ListItem>
  <asp:ListItem Value="Postpone">Not now</asp:ListItem>
  <asp:ListItem Value="Decline">Never!</asp:ListItem>
</asp:RadioButtonList>

The handler:

$(document).ready(function () {
  $("#<%=Intent.ClientID%>").change(function(){
   var rbvalue = $("input[name='<%=Intent.UniqueID%>']:radio:checked").val();

   if(rbvalue == "Confirm"){
    alert("Woohoo, Thanks!");
   } else if (rbvalue == "Postpone"){
    alert("Well, I really hope it's soon");
   } else if (rbvalue == "Decline"){
    alert("Shucks!");
   } else {
    alert("How'd you get here? Who sent you?");
   }
  });
});

The important part: $("input[name='<%=Intent.UniqueID%>']:radio:checked").val();

try:

wget -i text_file.txt

(check man wget)

This work for me

public  void waitForAjax(WebDriver driver) {
    new WebDriverWait(driver, 180).until(new ExpectedCondition<Boolean>(){

            JavascriptExecutor js = (JavascriptExecutor) driver;
            return (Boolean) js.executeScript("return jQuery.active == 0");
        }
    });
}

I do the following for my .NET Standard 2.0 projects.

Create a Directory.Build.props file (e.g. in the root of your repo) and move the properties to be shared from the .csproj file to this file.

MSBuild will pick it up automatically and apply them to the autogenerated AssemblyInfo.cs.

They also get applied to the nuget package when building one with dotnet pack or via the UI in Visual Studio 2017.

See https://docs.microsoft.com/en-us/visualstudio/msbuild/customize-your-build

Example:

<Project>
    <PropertyGroup>
        <Company>Some company</Company>
        <Copyright>Copyright © 2020</Copyright>
        <AssemblyVersion>1.0.0.1</AssemblyVersion>
        <FileVersion>1.0.0.1</FileVersion>
        <Version>1.0.0.1</Version>
        <!-- ... -->
    </PropertyGroup>

You have to add the android:screenOrientation="portrait" directive in your AndroidManifest.xml. This is to be done in your <activity> tag.

In addition, the Android Developers guide states that :

[...] you should also explicitly declare that your application requires either portrait or landscape orientation with the element. For example, <uses-feature android:name="android.hardware.screen.portrait" />.

Beyond Compare 3, my favorite, has a merge functionality in the Pro edition. The good thing with its merge is that it let you see all 4 views: base, left, right, and merged result. It's somewhat less visual than P4V but way more than WinDiff. It integrates with many source control and works on Windows/Linux. It has many features like advanced rules, editions, manual alignment...

The Perforce Visual Client (P4V) is a free tool that provides one of the most explicit interface for merging (see some screenshots). Works on all major platforms. My main disappointement with that tool is its kind of "read-only" interface. You cannot edit manually the files and you cannot manually align.

PS: P4Merge is included in P4V. Perforce tries to make it a bit hard to get their tool without their client.

SourceGear Diff/Merge may be my second free tool choice. Check that merge screens-shot and you'll see it's has the 3 views at least.

Meld is a newer free tool that I'd prefer to SourceGear Diff/Merge: Now it's also working on most platforms (Windows/Linux/Mac) with the distinct advantage of natively supporting some source control like Git. So you can have some history diff on all files much simpler. The merge view (see screenshot) has only 3 panes, just like SourceGear Diff/Merge. This makes merging somewhat harder in complex cases.

PS: If one tool one day supports 5 views merging, this would really be awesome, because if you cherry-pick commits in Git you really have not one base but two. Two base, two changes, and one resulting merge.

you can use this one in onCreateView, you can use transaction or replace

 OnBackPressedCallback callback = new OnBackPressedCallback(true) {
                @Override
                public void handleOnBackPressed() {
                    //what you want to do 
                }
            };
    requireActivity().getOnBackPressedDispatcher().addCallback(this, callback);

as long as "lots of stuff" isn't doing something asynchronous this is absolutely unneccessary - the event will call every handler on his way in sequence, so if theres a onklick-event on a parent-element this will fire after the onclik-event of the child has processed completely. javascript doesn't do some kind of "multithreading" here that makes "stopping" the event processing neccessary. conclusion: "pausing" an event just to resume it in the same handler doesn't make any sense.

if "lots of stuff" is something asynchronous this also doesn't make sense as it prevents the asynchonous things to do what they should do (asynchonous stuff) and make them bahave like everything is in sequence (where we come back to my first paragraph)

There is plugin called Partial Diff which helps to compare text selections within a file, across different files, or to the clipboard.

From the v3 documentation (Developer's Guide > Concepts > Developing for Mobile Devices):

Android and iOS devices respect the following <meta> tag:

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />

This setting specifies that the map should be displayed full-screen and should not be resizable by the user. Note that the iPhone's Safari browser requires this <meta> tag be included within the page's <head> element.

Multiply by 1.

result = 1. * a / b

or, using the float function

result = float(a) / b

Try this:

     string fileName = "6d294041-34d1-4c66-a04c-261a6d9aee17.jpeg";

     string deletePath= "/images/uploads/";

     if (!string.IsNullOrEmpty(fileName ))
        {
            // Append the name of the file to previous image.
            deletePath += fileName ;

            if (File.Exists(HttpContext.Current.Server.MapPath(deletePath)))
            {
                // deletevprevious image
                File.Delete(HttpContext.Current.Server.MapPath(deletePath));
            }
        }

Yes this is correct, you can't have variables in views (there are other restrictions too).

Views can be used for cases where the result can be replaced with a select statement.

you can use function bellow in order to generate your UUID

create or replace FUNCTION RANDOM_GUID
    RETURN VARCHAR2 IS

    RNG    NUMBER;
    N      BINARY_INTEGER;
    CCS    VARCHAR2 (128);
    XSTR   VARCHAR2 (4000) := NULL;
  BEGIN
    CCS := '0123456789' || 'ABCDEF';
    RNG := 15;

    FOR I IN 1 .. 32 LOOP
      N := TRUNC (RNG * DBMS_RANDOM.VALUE) + 1;
      XSTR := XSTR || SUBSTR (CCS, N, 1);
    END LOOP;

    RETURN SUBSTR(XSTR, 1, 4) || '-' ||
        SUBSTR(XSTR, 5, 4)        || '-' ||
        SUBSTR(XSTR, 9, 4)        || '-' ||
        SUBSTR(XSTR, 13,4)        || '-' ||
        SUBSTR(XSTR, 17,4)        || '-' ||
        SUBSTR(XSTR, 21,4)        || '-' ||
        SUBSTR(XSTR, 24,4)        || '-' ||
        SUBSTR(XSTR, 28,4);
END RANDOM_GUID;

Example of GUID genedrated by the function above:
8EA4-196D-BC48-9793-8AE8-5500-03DC-9D04

Here are two extension methods you can use. They ensure any existing classes are preserved and do not duplicate classes being added.

public static void RemoveCssClass(this WebControl control, String css) {
  control.CssClass = String.Join(" ", control.CssClass.Split(' ').Where(x => x != css).ToArray());
}

public static void AddCssClass(this WebControl control, String css) {
  control.RemoveCssClass(css);
  css += " " + control.CssClass;
  control.CssClass = css;
}

Usage: hlCreateNew.AddCssClass("disabled");

Usage: hlCreateNew.RemoveCssClass("disabled");

By default it will be hidden in your home directory. Type ls -a ~ to view that.

if you want to hide a whole div from the view in another screen size. You can follow bellow code as an example.

div.disabled{
  display: none;
}

Kotlin Solution:

1) Paste this extension function somewhere.

fun LocalDate.toDate(): Date = Date.from(this.atStartOfDay(ZoneId.systemDefault()).toInstant())

2) Use it, and never google this again.

val myDate = myLocalDate.toDate()

You missed the closing parenthesis at the end:

element = findElement(By.xpath("//[@test-id='test-username']"));

I use this. I think this is the simpliest way to do it:

 textBoxName.Clear();

Decode and save image as PNG

header('content-type: image/png');

           ob_start();

        $ret = fopen($fullurl, 'r', true, $context);
        $contents = stream_get_contents($ret);
        $base64 = 'data:image/PNG;base64,' . base64_encode($contents);
        echo "<img src=$base64 />" ;


        ob_end_flush();

you can use a simple regular expression for validating email id,

public boolean validateEmail(String email){
  return Pattern.matches("[_a-zA-Z1-9]+(\\.[A-Za-z0-9]*)*@[A-Za-z0-9]+\\.[A-Za-z0-9]+(\\.[A-Za-z0-9]*)*", email)
}

Description :

1. [_a-zA-Z1-9]+ - it will accept all A-Z,a-z, 0-9 and _ (+ mean it must be occur)
2. (\.[A-Za-z0-9]) - it's optional which will accept . and A-Z, a-z, 0-9( * mean its optional)
3. @[A-Za-z0-9]+ - it wil accept @ and A-Z,a-z,0-9
4. \.[A-Za-z0-9]+ - its for . and A-Z,a-z,0-9
5. (\.[A-Za-z0-9]) - it occur, . but its optional

I'm not sure if you can turn it off, but you can change the colors of it :)

myDiv::selection,
myDiv::-moz-selection,
myDiv::-webkit-selection {
    background:#000;
    color:#fff;
}

Then just match the colors to your "darky" design and see what happens :)

Answering the second part of your question,

Is there any standard or procedure one should follow to ensure there is no memory leak in the program.

Yes, there is. And this is one of the key differences between C and C++.

In C++, you should never call new or delete in your user code. RAII is a very commonly used technique, which pretty much solves the resource management problem. Every resource in your program (a resource is anything that has to be acquired, and then later on, released: file handles, network sockets, database connections, but also plain memory allocations, and in some cases, pairs of API calls (BeginX()/EndX(), LockY(), UnlockY()), should be wrapped in a class, where:

• the constructor acquires the resource (by calling new if the resource is a memroy allocation)
• the destructor releases the resource,
• copying and assignment is either prevented (by making the copy constructor and assignment operators private), or are implemented to work correctly (for example by cloning the underlying resource)

This class is then instantiated locally, on the stack, or as a class member, and not by calling new and storing a pointer.

You often don't need to define these classes yourself. The standard library containers behave in this way as well, so that any object stored into a std::vector gets freed when the vector is destroyed. So again, don't store a pointer into the container (which would require you to call new and delete), but rather the object itself (which gives you memory management for free). Likewise, smart pointer classes can be used to easily wrap objects that just have to be allocated with new, and control their lifetimes.

This means that when the object goes out of scope, it is automatically destroyed, and its resource released and cleaned up.

If you do this consistently throughout your code, you simply won't have any memory leaks. Everything that could get leaked is tied to a destructor which is guaranteed to be called when control leaves the scope in which the object was declared.

<button id="1" class="clickMe"></button>
<button id="2" class="clickMe"></button>
<button id="3" class="clickMe"></button>

<script>
$('.clickMe').click(function(){
    alert(this.id);
});
</script>

A word of warning: though padding-right might solve your particular (visual) problem, it is not the right way to add spacing between table cells. What padding-right does for a cell is similar to what it does for most other elements: it adds space within the cell. If the cells do not have a border or background colour or something else that gives the game away, this can mimic the effect of setting the space between the cells, but not otherwise.

As someone noted, margin specifications are ignored for table cells:

CSS 2.1 Specification – Tables – Visual layout of table contents

Internal table elements generate rectangular boxes with content and borders. Cells have padding as well. Internal table elements do not have margins.

What's the "right" way then? If you are looking to replace the cellspacing attribute of the table, then border-spacing (with border-collapse disabled) is a replacement. However, if per-cell "margins" are required, I am not sure how that can be correctly achieved using CSS. The only hack I can think of is to use padding as above, avoid any styling of the cells (background colours, borders, etc.) and instead use container DIVs inside the cells to implement such styling.

I am not a CSS expert, so I could well be wrong in the above (which would be great to know! I too would like a table cell margin CSS solution).

Cheers!

fiddle

var $select = $('#down'); 
$select.find('option').remove();  
$.each(temp,function(key, value) 
{
    $select.append('<option value=' + key + '>' + value + '</option>');
});

I can see that this question was originally posted 5 yrs ago when programmers had to work harder to get their desired results. With Visual Studio 2012 and beyond, a lazy programmer can go the Design View for the Listview properties settings, and click on Properties->Sorting, choose Ascending. There are plenty of other properties features to obtain the various results a lazy (aka smart) programmer can leverage.

As Marcelo suggests:

UPDATE mytable
SET new_column = <expr containing old_column>;

If this takes too long and fails due to "snapshot too old" errors (e.g. if the expression queries another highly-active table), and if the new value for the column is always NOT NULL, you could update the table in batches:

UPDATE mytable
SET new_column = <expr containing old_column>
WHERE new_column IS NULL
AND ROWNUM <= 100000;

Just run this statement, COMMIT, then run it again; rinse, repeat until it reports "0 rows updated". It'll take longer but each update is less likely to fail.

EDIT:

A better alternative that should be more efficient is to use the DBMS_PARALLEL_EXECUTE API.

Sample code (from Oracle docs):

DECLARE
  l_sql_stmt VARCHAR2(1000);
  l_try NUMBER;
  l_status NUMBER;
BEGIN

  -- Create the TASK
  DBMS_PARALLEL_EXECUTE.CREATE_TASK ('mytask');

  -- Chunk the table by ROWID
  DBMS_PARALLEL_EXECUTE.CREATE_CHUNKS_BY_ROWID('mytask', 'HR', 'EMPLOYEES', true, 100);

  -- Execute the DML in parallel
  l_sql_stmt := 'update EMPLOYEES e 
      SET e.salary = e.salary + 10
      WHERE rowid BETWEEN :start_id AND :end_id';
  DBMS_PARALLEL_EXECUTE.RUN_TASK('mytask', l_sql_stmt, DBMS_SQL.NATIVE,
                                 parallel_level => 10);

  -- If there is an error, RESUME it for at most 2 times.
  l_try := 0;
  l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
  WHILE(l_try < 2 and l_status != DBMS_PARALLEL_EXECUTE.FINISHED) 
  LOOP
    l_try := l_try + 1;
    DBMS_PARALLEL_EXECUTE.RESUME_TASK('mytask');
    l_status := DBMS_PARALLEL_EXECUTE.TASK_STATUS('mytask');
  END LOOP;

  -- Done with processing; drop the task
  DBMS_PARALLEL_EXECUTE.DROP_TASK('mytask');

END;
/

The --binary-files=without-match option to GNU grep gets it to skip binary files. (Equivalent to the -I switch mentioned elsewhere.)

(This might require a recent version of grep; 2.5.3 has it, at least.)

You can convert the input to base 26 (Hexavigesimal) and convert each "digit" back to base 10 individually and apply the ASCII mapping. Since A is mapped to 0, you will get results A, B, C,..., Y, Z, BA, BB, BC,...etc, which may or may not be desirable depending on your requirements for input values > 26, since it may be natural to think AA comes after Z.

public static String getCharForNumber(int i){

    // return null for bad input
    if(i < 0){
        return null;
    }

    // convert to base 26
    String s = Integer.toString(i, 26);

    char[] characters = s.toCharArray();

    String result = "";
    for(char c : characters){
        // convert the base 26 character back to a base 10 integer
        int x = Integer.parseInt(Character.valueOf(c).toString(), 26);
        // append the ASCII value to the result
        result += String.valueOf((char)(x + 'A'));          
    }

    return result;
}

On pure JS:

let select = document.getElementById("select_id")                   
let to_hide = select[select.selectedIndex];
to_hide.setAttribute('hidden', 'hidden');

to unhide just

to_hide.removeAttr('hidden');

or

to_hide.hidden = true;   // to hide
to_hide.hidden = false;  // to unhide

For large arrays, the (excellent) answer given by @Demitri is far faster than the answer currently marked as best. I've adapted his exact algorithm in the following two ways:

1. The function below works whether or not the input array is sorted.

2. The function below returns the index of the input array corresponding to the closest value, which is somewhat more general.

Note that the function below also handles a specific edge case that would lead to a bug in the original function written by @Demitri. Otherwise, my algorithm is identical to his.

def find_idx_nearest_val(array, value):
    idx_sorted = np.argsort(array)
    sorted_array = np.array(array[idx_sorted])
    idx = np.searchsorted(sorted_array, value, side="left")
    if idx >= len(array):
        idx_nearest = idx_sorted[len(array)-1]
    elif idx == 0:
        idx_nearest = idx_sorted[0]
    else:
        if abs(value - sorted_array[idx-1]) < abs(value - sorted_array[idx]):
            idx_nearest = idx_sorted[idx-1]
        else:
            idx_nearest = idx_sorted[idx]
    return idx_nearest

You can drop the new string[] part:

List<string> values = new List<string> { "one", "two", "three" };

Make a javascript function

function addSampleTextInInputBox(message) {
    //set value in input box
    document.getElementById('textInput').value = message + "";
    //or show an alert
    //window.alert(message);
}

Then simply call in your table row button click

<td class="center">
    <a class="btn btn-success" onclick="addSampleTextInInputBox('<?php echo $row->message; ?>')" title="Add" data-toggle="tooltip" title="Add">
        <span class="fa fa-plus"></span>
    </a>
</td>

In Bootstrap 4 they use box-shadow: 0 0 0 0px rgba(0,123,255,0); on :focus, si i solved my problem with

a.active.focus,
a.active:focus,
a.focus,
a:active.focus,
a:active:focus,
a:focus,
button.active.focus,
button.active:focus,
button.focus,
button:active.focus,
button:active:focus,
button:focus,
.btn.active.focus,
.btn.active:focus,
.btn.focus,
.btn:active.focus,
.btn:active:focus,
.btn:focus {
    outline: 0;
    outline-color: transparent;
    outline-width: 0;
    outline-style: none;
    box-shadow: 0 0 0 0 rgba(0,123,255,0);
}

More Safety - With Kotlin

Most of the answers use Handler but I give a different solution to delay in activity, fragment, view model with Android Lifecycle ext. This way will auto cancel when the lifecycle begins destroyed.

In Activity or Fragment:

lifecycleScope.launch { 
  delay(DELAY_MS)
  doSomething()
}

In ViewModel:

viewModelScope.lanch {
  delay(DELAY_MS)
  doSomething()
}

In suspend function: (Kotlin Coroutine)

suspend fun doSomethingAfter(){
    delay(DELAY_MS)
    doSomething()
}

If you get an error with the lifecycleScope not found - import to gradle file:

implementation "androidx.lifecycle:lifecycle-runtime-ktx:2.2.0"

See Wikipedia article on this topic. Sample Manacher's Algorithm Java implementation for linear O(n) solution from the article below:

import java.util.Arrays; public class ManachersAlgorithm { public static String findLongestPalindrome(String s) { if (s==null || s.length()==0) return "";

char[] s2 = addBoundaries(s.toCharArray());
int[] p = new int[s2.length]; 
int c = 0, r = 0; // Here the first element in s2 has been processed.
int m = 0, n = 0; // The walking indices to compare if two elements are the same
for (int i = 1; i<s2.length; i++) {
  if (i>r) {
    p[i] = 0; m = i-1; n = i+1;
  } else {
    int i2 = c*2-i;
    if (p[i2]<(r-i)) {
      p[i] = p[i2];
      m = -1; // This signals bypassing the while loop below. 
    } else {
      p[i] = r-i;
      n = r+1; m = i*2-n;
    }
  }
  while (m>=0 && n<s2.length && s2[m]==s2[n]) {
    p[i]++; m--; n++;
  }
  if ((i+p[i])>r) {
    c = i; r = i+p[i];
  }
}
int len = 0; c = 0;
for (int i = 1; i<s2.length; i++) {
  if (len<p[i]) {
    len = p[i]; c = i;
  }
}
char[] ss = Arrays.copyOfRange(s2, c-len, c+len+1);
return String.valueOf(removeBoundaries(ss));   }
private static char[] addBoundaries(char[] cs) {
if (cs==null || cs.length==0)
  return "||".toCharArray();

char[] cs2 = new char[cs.length*2+1];
for (int i = 0; i<(cs2.length-1); i = i+2) {
  cs2[i] = '|';
  cs2[i+1] = cs[i/2];
}
cs2[cs2.length-1] = '|';
return cs2;   }
private static char[] removeBoundaries(char[] cs) {
if (cs==null || cs.length<3)
  return "".toCharArray();

char[] cs2 = new char[(cs.length-1)/2];
for (int i = 0; i<cs2.length; i++) {
  cs2[i] = cs[i*2+1];
}
return cs2;   }     }

your query can go as follows:

$query = "INSERT INTO data (notes, id, filesUploaded, lat, lng, intLat, intLng)
      VALUES ('$notes', '$id', TRIM('$imageUploaded'), '$lat', '$lng', '" . ($lat == '')?NULL:$lat . "', '" . ($long == '')?NULL:$long . "')";
mysql_query($query);

To answer my own question, this functionality has been added to pandas in the meantime. Starting from pandas 0.15.0, you can use tz_localize(None) to remove the timezone resulting in local time.
See the whatsnew entry: http://pandas.pydata.org/pandas-docs/stable/whatsnew.html#timezone-handling-improvements

So with my example from above:

In [4]: t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H',
                          tz= "Europe/Brussels")

In [5]: t
Out[5]: DatetimeIndex(['2013-05-18 12:00:00+02:00', '2013-05-18 13:00:00+02:00'],
                       dtype='datetime64[ns, Europe/Brussels]', freq='H')

using tz_localize(None) removes the timezone information resulting in naive local time:

In [6]: t.tz_localize(None)
Out[6]: DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], 
                      dtype='datetime64[ns]', freq='H')

Further, you can also use tz_convert(None) to remove the timezone information but converting to UTC, so yielding naive UTC time:

In [7]: t.tz_convert(None)
Out[7]: DatetimeIndex(['2013-05-18 10:00:00', '2013-05-18 11:00:00'], 
                      dtype='datetime64[ns]', freq='H')

This is much more performant than the datetime.replace solution:

In [31]: t = pd.date_range(start="2013-05-18 12:00:00", periods=10000, freq='H',
                           tz="Europe/Brussels")

In [32]: %timeit t.tz_localize(None)
1000 loops, best of 3: 233 µs per loop

In [33]: %timeit pd.DatetimeIndex([i.replace(tzinfo=None) for i in t])
10 loops, best of 3: 99.7 ms per loop

It's a shorthand for this:

<?php echo $a; ?>

They're called short tags; see example #2 in the documentation.

Hey define color #000 into as like you and modify your css as like this

.navBtn { text-decoration: none; color:#000; }
.navBtn:visited { text-decoration: none; color:#000; }
.navBtn:hover { text-decoration: none; color:#000; }
.navBtn:focus { text-decoration: none; color:#000; }
.navBtn:hover, .navBtn:active { text-decoration: none; color:#000; }

or this

 li a { text-decoration: none; color:#000; }
 li a:visited { text-decoration: none; color:#000; }
 li a:hover { text-decoration: none; color:#000; }
 li a:focus { text-decoration: none; color:#000; }
 li a:hover, .navBtn:active { text-decoration: none; color:#000; }

You may want to try the following:

SELECT  l.position, 
        l.username, 
        l.score,
        @curRow := @curRow + 1 AS row_number
FROM    league_girl l
JOIN    (SELECT @curRow := 0) r;

The JOIN (SELECT @curRow := 0) part allows the variable initialization without requiring a separate SET command.

Test case:

CREATE TABLE league_girl (position int, username varchar(10), score int);
INSERT INTO league_girl VALUES (1, 'a', 10);
INSERT INTO league_girl VALUES (2, 'b', 25);
INSERT INTO league_girl VALUES (3, 'c', 75);
INSERT INTO league_girl VALUES (4, 'd', 25);
INSERT INTO league_girl VALUES (5, 'e', 55);
INSERT INTO league_girl VALUES (6, 'f', 80);
INSERT INTO league_girl VALUES (7, 'g', 15);

Test query:

SELECT  l.position, 
        l.username, 
        l.score,
        @curRow := @curRow + 1 AS row_number
FROM    league_girl l
JOIN    (SELECT @curRow := 0) r
WHERE   l.score > 50;

Result:

+----------+----------+-------+------------+
| position | username | score | row_number |
+----------+----------+-------+------------+
|        3 | c        |    75 |          1 |
|        5 | e        |    55 |          2 |
|        6 | f        |    80 |          3 |
+----------+----------+-------+------------+
3 rows in set (0.00 sec)

Or like this:

List< KeyValuePair< string, int > > theList =
    new List< KeyValuePair< string,int > >(this.yourDictionary);

for ( int i = 0; i < theList.Count; i++)
{ 
  // the key
  Console.WriteLine(theList[i].Key);
}

Its almost like you have to wipe out your computer to get rid of the old dll. I have already tried everything above and then I went the extra step of just deleting every instance of the .DLL file that was on my computer and removing every reference from the application. However, it still compiles just fine and when it runs it is referencing the dll functions just fine. I'm starting to wonder if it is referencing it from a network drive somehwere.

Your array is occupying roughly 8 GB of memory (1,000 x 1,000,000 x sizeof(double) bytes). That might be a factor in your problem. It is a global variable rather than a stack variable, so you may be OK, but you're pushing limits here.

Writing that much data to a file is going to take a while.

You don't check that the file was opened successfully, which could be a source of trouble, too (if it did fail, a segmentation fault is very likely).

You really should introduce some named constants for 1,000 and 1,000,000; what do they represent?

You should also write a function to do the calculation; you could use an inline function in C99 or later (or C++). The repetition in the code is excruciating to behold.

You should also use C99 notation for main(), with the explicit return type (and preferably void for the argument list when you are not using argc or argv):

int main(void)

Out of idle curiosity, I took a copy of your code, changed all occurrences of 1000 to ROWS, all occurrences of 1000000 to COLS, and then created enum { ROWS = 1000, COLS = 10000 }; (thereby reducing the problem size by a factor of 100). I made a few minor changes so it would compile cleanly under my preferred set of compilation options (nothing serious: static in front of the functions, and the main array; file becomes a local to main; error check the fopen(), etc.).

I then created a second copy and created an inline function to do the repeated calculation, (and a second one to do subscript calculations). This means that the monstrous expression is only written out once — which is highly desirable as it ensure consistency.

This program writes to P2.txt instead of P1.txt. I ran both programs and compared the output files; the output was identical. When I ran the programs on a mostly idle machine (MacBook Pro, 2.3 GHz Intel Core i7, 16 GiB 1333 MHz RAM, Mac OS X 10.7.5, GCC 4.7.1), I got reasonably but not wholly consistent timing:

Original   Modified

6.241s      6.231s
6.315s     10.778s

8.972s      6.370s
6.383s      6.357s

However, almost all that time is spent on disk I/O. I reduced the disk I/O to just the very last row of data, so the outer I/O for loop became:

for (int i = COLS - 1; i < COLS; i++)

the timings were vastly reduced and very much more consistent:

The simplification in the code from having the ghastly expression written out just once is very beneficial, it seems to me. I'd certainly far rather have to maintain that program than the original.

Wanted to add my solution:

< br/ >

which is basically the same as was suggested above
In my case I had to use &lt for < and &gt for > Simply putting <br /> did not work.

For me setting width / height to the img worked. <asp:Image runat="server" ID="Icon" Style="max-width: 50px; max-height: 50px; position: relative;" />

There are no standard exit codes, aside from 0 meaning success. Non-zero doesn't necessarily mean failure either.

stdlib.h does define EXIT_FAILURE as 1 and EXIT_SUCCESS as 0, but that's about it.

The 11 on segfault is interesting, as 11 is the signal number that the kernel uses to kill the process in the event of a segfault. There is likely some mechanism, either in the kernel or in the shell, that translates that into the exit code.

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

I think this works for SQL 2000:

SELECT 
    CASE WHEN C.autoval IS NOT NULL THEN
        'Identity'
    ELSE
        'Not Identity'
    AND
FROM
    sysobjects O
INNER JOIN
    syscolumns C
ON
    O.id = C.id
WHERE
    O.NAME = @TableName
AND
    C.NAME = @ColumnName

No magic involved, just subtract from the offset top of the element

$('html, body').animate({scrollTop: $('#contact').offset().top -100 }, 'slow');

ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;

This is all you need to:

1. Add the id column
2. Populate it with a sequence from 1 to count(*).
3. Set it as primary key / not null.

A solution in C# would be:

Helper class:

internal class DriverHelper
{

    private IWebDriver Driver { get; set; }
    private WebDriverWait Wait { get; set; }

    public DriverHelper(string driverUrl, int timeoutInSeconds)
    {
        Driver = new ChromeDriver();
        Driver.Url = driverUrl;
        Wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(timeoutInSeconds));
    }

    internal bool ClickElement(string cssSelector)
    {
        //Find the element
        IWebElement element = Wait.Until(d=>ExpectedConditions.ElementIsVisible(By.CssSelector(cssSelector)))(Driver);
        return Wait.Until(c => ClickElement(element, cssSelector));
    }

    private bool ClickElement(IWebElement element, string cssSelector)
    {
        try
        {
            //Check if element is still included in the dom
            //If the element has changed a the OpenQA.Selenium.StaleElementReferenceException is thrown.
            bool isDisplayed = element.Displayed;

            element.Click();
            return true;
        }
        catch (StaleElementReferenceException)
        {
            //wait until the element is visible again
            element = Wait.Until(d => ExpectedConditions.ElementIsVisible(By.CssSelector(cssSelector)))(Driver);
            return ClickElement(element, cssSelector);
        }
        catch (Exception)
        {
            return false;
        }
    }
}

Invocation:

        DriverHelper driverHelper = new DriverHelper("http://www.seleniumhq.org/docs/04_webdriver_advanced.jsp", 10);
        driverHelper.ClickElement("input[value='csharp']:first-child");

Similarly can be used for Java.

Simplest solution:

public class RomanNumerals {

    private static int [] arabic = {50, 40, 10, 9, 5, 4, 1};

    private static String [] roman = {"L", "XL", "X", "IX", "V", "IV", "I"};

    public static String convert(int arabicNumber) {

        StringBuilder romanNumerals = new StringBuilder();
        int remainder = arabicNumber;

        for (int i=0;i<arabic.length;i++) {

            while (remainder >= arabic[i]) {
                romanNumerals.append(roman[i]);
                remainder -= arabic[i];
            }
        }

        return romanNumerals.toString();
    }
}

Just want to add another way of doing this. I've seen multiple people on various related threads ask if you can use VerifyRenderingInServerForm without adding it to the parent page.

You actually can do this but it's a bit of a bodge.

First off create a new Page class which looks something like the following:

public partial class NoRenderPage : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    { }

    public override void VerifyRenderingInServerForm(Control control)
    {
        //Allows for printing
    }

    public override bool EnableEventValidation
    {
        get { return false; }
        set { /*Do nothing*/ }
    }
}

Does not need to have an .ASPX associated with it.

Then in the control you wish to render you can do something like the following.

    StringWriter tw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(tw);

    var page = new NoRenderPage();
    page.DesignerInitialize();
    var form = new HtmlForm();
    page.Controls.Add(form);
    form.Controls.Add(pnl);
    controlToRender.RenderControl(hw);

Now you've got your original control rendered as HTML. If you need to, add the control back into it's original position. You now have the HTML rendered, the page as normal and no changes to the page itself.

This URL format worked like a charm:

http://maps.google.com/maps?&z={INSERT_MAP_ZOOM}&mrt={INSERT_TYPE_OF_SEARCH}&t={INSERT_MAP_TYPE}&q={INSERT_MAP_LAT_COORDINATES}+{INSERT_MAP_LONG_COORDINATES}

Example for Mount Everest:

Some Bash tricks I use to set variables from commands

Sorry, there is a loong answer, but as bash is a shell, where the main goal is to run other unix commands and react to resut code and/or output, ( commands are often piped filter, etc... ).

Storing command output in variables is something basic and fundamental.

Therefore, depending on

• compatibility (posix)
• kind of output (filter(s))
• number of variable to set (split or interpret)
• execution time (monitoring)
• error trapping
• repeatability of request (see long running background process, further)
• interactivity (considering user input while reading from another input file descriptor)
• do I miss something?

First simple, old, and compatible way

myPi=`echo '4*a(1)' | bc -l`
echo $myPi 
3.14159265358979323844

Mostly compatible, second way

As nesting could become heavy, parenthesis was implemented for this

myPi=$(bc -l <<<'4*a(1)')

Nested sample:

SysStarted=$(date -d "$(ps ho lstart 1)" +%s)
echo $SysStarted 
1480656334

bash features

Reading more than one variable (with Bashisms)

df -k /
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/dm-0         999320 529020    401488  57% /

If I just want a used value:

array=($(df -k /))

you could see an array variable:

declare -p array
declare -a array='([0]="Filesystem" [1]="1K-blocks" [2]="Used" [3]="Available" [
4]="Use%" [5]="Mounted" [6]="on" [7]="/dev/dm-0" [8]="999320" [9]="529020" [10]=
"401488" [11]="57%" [12]="/")'

Then:

echo ${array[9]}
529020

But I often use this:

{ read foo ; read filesystem size using avail prct mountpoint ; } < <(df -k /)
echo $using
529020

The first read foo will just skip header line, but in only one command, you will populate 7 different variables:

declare -p avail filesystem foo mountpoint prct size using
declare -- avail="401488"
declare -- filesystem="/dev/dm-0"
declare -- foo="Filesystem     1K-blocks   Used Available Use% Mounted on"
declare -- mountpoint="/"
declare -- prct="57%"
declare -- size="999320"
declare -- using="529020"

Or

{ read -a head;varnames=(${head[@]//[K1% -]});varnames=(${head[@]//[K1% -]});
  read ${varnames[@],,} ; } < <(LANG=C df -k /)

Then:

declare -p varnames ${varnames[@],,} 
declare -a varnames=([0]="Filesystem" [1]="blocks" [2]="Used" [3]="Available" [4]="Use" [5]="Mounted" [6]="on")
declare -- filesystem="/dev/dm-0"
declare -- blocks="999320"
declare -- used="529020"
declare -- available="401488"
declare -- use="57%"
declare -- mounted="/"
declare -- on=""

Or even:

{ read foo ; read filesystem dsk[{6,2,9}] prct mountpoint ; } < <(df -k /)
declare -p mountpoint dsk
declare -- mountpoint="/"
declare -a dsk=([2]="529020" [6]="999320" [9]="401488")

(Note Used and Blocks is switched there: read ... dsk[6] dsk[2] dsk[9] ...)

... will work with associative arrays too: read foo disk[total] disk[used] ...

Dedicated fd using unnamed fifo:

There is an elegent way:

users=()
while IFS=: read -u $list user pass uid gid name home bin ;do
    ((uid>=500)) &&
        printf -v users[uid] "%11d %7d %-20s %s\n" $uid $gid $user $home
done {list}</etc/passwd

Using this way (... read -u $list; ... {list}<inputfile) leave STDIN free for other purposes, like user interaction.

Then

echo -n "${users[@]}"
       1000    1000 user         /home/user
...
      65534   65534 nobody       /nonexistent

and

echo ${!users[@]}
1000 ... 65534

echo -n "${users[1000]}"
      1000    1000 user       /home/user

This could be used with static files or even /dev/tcp/xx.xx.xx.xx/yyy with x for ip address or hostname and y for port number:

{
    read -u $list -a head          # read header in array `head`
    varnames=(${head[@]//[K1% -]}) # drop illegal chars for variable names
    while read -u $list ${varnames[@],,} ;do
        ((pct=available*100/(available+used),pct<10)) &&
            printf "WARN: FS: %-20s on %-14s %3d <10 (Total: %11u, Use: %7s)\n" \
                "${filesystem#*/mapper/}" "$mounted" $pct $blocks "$use"
     done
 } {list}< <(LANG=C df -k)

And of course with inline documents:

while IFS=\; read -u $list -a myvar ;do
    echo ${myvar[2]}
done {list}<<"eof"
foo;bar;baz
alice;bob;charlie
$cherry;$strawberry;$memberberries
eof

Sample function for populating some variables:

#!/bin/bash

declare free=0 total=0 used=0

getDiskStat() {
    local foo
    {
        read foo
        read foo total used free foo
    } < <(
        df -k ${1:-/}
    )
}

getDiskStat $1
echo $total $used $free

Nota: declare line is not required, just for readability.

About sudo cmd | grep ... | cut ...

shell=$(cat /etc/passwd | grep $USER | cut -d : -f 7)
echo $shell
/bin/bash

(Please avoid useless cat! So this is just one fork less:

shell=$(grep $USER </etc/passwd | cut -d : -f 7)

All pipes (|) implies forks. Where another process have to be run, accessing disk, libraries calls and so on.

So using sed for sample, will limit subprocess to only one fork:

shell=$(sed </etc/passwd "s/^$USER:.*://p;d")
echo $shell

And with Bashisms:

But for many actions, mostly on small files, Bash could do the job itself:

while IFS=: read -a line ; do
    [ "$line" = "$USER" ] && shell=${line[6]}
  done </etc/passwd
echo $shell
/bin/bash

or

while IFS=: read loginname encpass uid gid fullname home shell;do
    [ "$loginname" = "$USER" ] && break
  done </etc/passwd
echo $shell $loginname ...

Going further about variable splitting...

Have a look at my answer to How do I split a string on a delimiter in Bash?

Alternative: reducing forks by using backgrounded long-running tasks

In order to prevent multiple forks like

myPi=$(bc -l <<<'4*a(1)'
myRay=12
myCirc=$(bc -l <<<" 2 * $myPi * $myRay ")

or

myStarted=$(date -d "$(ps ho lstart 1)" +%s)
mySessStart=$(date -d "$(ps ho lstart $$)" +%s)

This work fine, but running many forks is heavy and slow.

And commands like date and bc could make many operations, line by line!!

See:

bc -l <<<$'3*4\n5*6'
12
30

date -f - +%s < <(ps ho lstart 1 $$)
1516030449
1517853288

So we could use a long running background process to make many jobs, without having to initiate a new fork for each request.

Under bash, there is a built-in function: coproc:

coproc bc -l
echo 4*3 >&${COPROC[1]}
read -u $COPROC answer
echo $answer
12

echo >&${COPROC[1]} 'pi=4*a(1)'
ray=42.0
printf >&${COPROC[1]} '2*pi*%s\n' $ray
read -u $COPROC answer
echo $answer
263.89378290154263202896

printf >&${COPROC[1]} 'pi*%s^2\n' $ray
read -u $COPROC answer
echo $answer
5541.76944093239527260816

As bc is ready, running in background and I/O are ready too, there is no delay, nothing to load, open, close, before or after operation. Only the operation himself! This become a lot quicker than having to fork to bc for each operation!

Border effect: While bc stay running, they will hold all registers, so some variables or functions could be defined at initialisation step, as first write to ${COPROC[1]}, just after starting the task (via coproc).

Into a function newConnector

You may found my newConnector function on GitHub.Com or on my own site (Note on GitHub: there are two files on my site. Function and demo are bundled into one uniq file which could be sourced for use or just run for demo.)

Sample:

source shell_connector.sh

tty
/dev/pts/20

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30745 pts/20   R+     0:00  \_ ps --tty pts/20 fw

newConnector /usr/bin/bc "-l" '3*4' 12

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30944 pts/20   S      0:00  \_ /usr/bin/bc -l
  30952 pts/20   R+     0:00  \_ ps --tty pts/20 fw

declare -p PI
bash: declare: PI: not found

myBc '4*a(1)' PI
declare -p PI
declare -- PI="3.14159265358979323844"

The function myBc lets you use the background task with simple syntax, and for date:

newConnector /bin/date '-f - +%s' @0 0
myDate '2000-01-01'
  946681200
myDate "$(ps ho lstart 1)" boottime
myDate now now ; read utm idl </proc/uptime
myBc "$now-$boottime" uptime
printf "%s\n" ${utm%%.*} $uptime
  42134906
  42134906

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30944 pts/20   S      0:00  \_ /usr/bin/bc -l
  32615 pts/20   S      0:00  \_ /bin/date -f - +%s
   3162 pts/20   R+     0:00  \_ ps --tty pts/20 fw

From there, if you want to end one of background processes, you just have to close its fd:

eval "exec $DATEOUT>&-"
eval "exec $DATEIN>&-"
ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
   4936 pts/20   Ss     0:00 bash
   5256 pts/20   S      0:00  \_ /usr/bin/bc -l
   6358 pts/20   R+     0:00  \_ ps --tty pts/20 fw

which is not needed, because all fd close when the main process finishes.

Prepend the url prefix git+ (See VCS Support):

pip install git+https://github.com/tangentlabs/django-oscar-paypal.git@issue/34/oscar-0.6

And specify the branch name without the leading /.

you can also try the more generic version which gives you the ith element

enumerable.ElementAtOrDefault(i));

hope it helps

You must make Foo::comparator static or wrap it in a std::mem_fun class object. This is because lower_bounds() expects the comparer to be a class of object that has a call operator, like a function pointer or a functor object. Also, if you are using C++11 or later, you can also do as dwcanillas suggests and use a lambda function. C++11 also has std::bind too.

Examples:

// Binding:
std::lower_bounds(first, last, value, std::bind(&Foo::comparitor, this, _1, _2));
// Lambda:
std::lower_bounds(first, last, value, [](const Bar & first, const Bar & second) { return ...; });

This class will help and then initialize the class with the init method.

import 'package:flutter/widgets.dart';

class SizeConfig {
  static MediaQueryData _mediaQueryData;
  static double screenWidth;
  static double screenHeight;
  static double blockSizeHorizontal;
  static double blockSizeVertical;
  static double _safeAreaHorizontal;
  static double _safeAreaVertical;
  static double safeBlockHorizontal;
  static double safeBlockVertical;

  void init(BuildContext context){
    _mediaQueryData = MediaQuery.of(context);
    screenWidth = _mediaQueryData.size.width;
    screenHeight = _mediaQueryData.size.height;
    blockSizeHorizontal = screenWidth/100;
    blockSizeVertical = screenHeight/100;
    _safeAreaHorizontal = _mediaQueryData.padding.left +
        _mediaQueryData.padding.right;
    _safeAreaVertical = _mediaQueryData.padding.top +
        _mediaQueryData.padding.bottom;
    safeBlockHorizontal = (screenWidth - _safeAreaHorizontal)/100;
    safeBlockVertical = (screenHeight - _safeAreaVertical)/100;
  }
}

then in your widgets dimension do this

Widget build(BuildContext context) {
    SizeConfig().init(context);
    return Container(
    height: SizeConfig.safeBlockVertical * 10, //10 for example
    width: SizeConfig.safeBlockHorizontal * 10, //10 for example
    );}

To complement @Joe's answer:

Hamcrest provides you with three main methods to match a list:

contains Checks for matching all the elements taking in count the order, if the list has more or less elements, it will fail

containsInAnyOrder Checks for matching all the elements and it doesn't matter the order, if the list has more or less elements, will fail

hasItems Checks just for the specified objects it doesn't matter if the list has more

hasItem Checks just for one object it doesn't matter if the list has more

All of them can receive a list of objects and use equals method for comparation or can be mixed with other matchers like @borjab mentioned:

assertThat(myList , contains(allOf(hasProperty("id", is(7L)),

Check if string contains specific words?

This means the string has to be resolved into words (see note below).

One way to do this and to specify the separators is using preg_split (doc):

<?php

function contains_word($str, $word) {
  // split string into words
  // separators are substrings of at least one non-word character
  $arr = preg_split('/\W+/', $str, NULL, PREG_SPLIT_NO_EMPTY);

  // now the words can be examined each
  foreach ($arr as $value) {
    if ($value === $word) {
      return true;
    }
  }
  return false;
}

function test($str, $word) {
  if (contains_word($str, $word)) {
    echo "string '" . $str . "' contains word '" . $word . "'\n";
  } else {
    echo "string '" . $str . "' does not contain word '" . $word . "'\n" ;
  }
}

$a = 'How are you?';

test($a, 'are');
test($a, 'ar');
test($a, 'hare');

?>

A run gives

$ php -f test.php                   
string 'How are you?' contains word 'are' 
string 'How are you?' does not contain word 'ar'
string 'How are you?' does not contain word 'hare'

Note: Here we do not mean word for every sequence of symbols.

A practical definition of word is in the sense the PCRE regular expression engine, where words are substrings consisting of word characters only, being separated by non-word characters.

A "word" character is any letter or digit or the underscore character, that is, any character which can be part of a Perl " word ". The definition of letters and digits is controlled by PCRE's character tables, and may vary if locale-specific matching is taking place (..)

If you are reading this and you are using Spring Boot, you have 1 more option for this feature

Usually comma separated list are very clumsy for real world use case (And sometime not even feasible, if you want to use commas in your config):

[email protected],[email protected],[email protected],.....

With Spring Boot, you can write it like these (Index start at 0):

email.sendTo[0][email protected]
email.sendTo[1][email protected]
email.sendTo[2][email protected]

And use it like these:

@Component
@ConfigurationProperties("email")
public class EmailProperties {

    private List<String> sendTo;

    public List<String> getSendTo() {
        return sendTo;
    }

    public void setSendTo(List<String> sendTo) {
        this.sendTo = sendTo;
    }

}


@Component
public class EmailModel {

  @Autowired
  private EmailProperties emailProperties;

  //Use the sendTo List by 
  //emailProperties.getSendTo()

}



@Configuration
public class YourConfiguration {
    @Bean
  public EmailProperties emailProperties(){
        return new EmailProperties();
  }

}


#Put this in src/main/resource/META-INF/spring.factories
  org.springframework.boot.autoconfigure.EnableAutoConfiguration=example.compackage.YourConfiguration

pyspark.sql.functions.split() is the right approach here - you simply need to flatten the nested ArrayType column into multiple top-level columns. In this case, where each array only contains 2 items, it's very easy. You simply use Column.getItem() to retrieve each part of the array as a column itself:

split_col = pyspark.sql.functions.split(df['my_str_col'], '-')
df = df.withColumn('NAME1', split_col.getItem(0))
df = df.withColumn('NAME2', split_col.getItem(1))

The result will be:

col1 | my_str_col | NAME1 | NAME2
-----+------------+-------+------
  18 |  856-yygrm |   856 | yygrm
 201 |  777-psgdg |   777 | psgdg

I am not sure how I would solve this in a general case where the nested arrays were not the same size from Row to Row.

You can pass semicolon separated values as command argument and then split the string and use it.

<asp:TemplateField ShowHeader="false">
    <ItemTemplate>
       <asp:LinkButton ID="lnkCustomize" Text="Customize"  CommandName="Customize"  CommandArgument='<%#Eval("IdTemplate") + ";" +Eval("EntityId")%>'  runat="server"> 
       </asp:LinkButton>   
    </ItemTemplate>   
</asp:TemplateField>

at server side

protected void gridview_RowCommand(object sender, GridViewCommandEventArgs e)
{
      string[] arg = new string[2];
      arg = e.CommandArgument.ToString().Split(';');
      Session["IdTemplate"] = arg[0];
      Session["IdEntity"] = arg[1];
      Response.Redirect("Samplepage.aspx");
}

Hope it helps!!!!

If you logged into "phpmyadmin", then logged out, you might have trouble attempting to log back in on the same browser window. The logout sends the browser to a URL that looks like this:

http://localhost/phpmyadmin/index.php?db=&token=354a350abed02588e4b59f44217826fd&old_usr=tester

But for me, on Mac OS X in Safari browser, that URL just doesn't want to work. Therefore, I have to put in the clean URL:

http://localhost/phpmyadmin

Don't know why, but as of today, Oct 20, 2015, that is what I am experiencing.

It is a trivial process. You can see a good example in the source code SMSPopup

Examine the following methods:

SmsMmsMessage getSmsDetails(Context context, long ignoreThreadId, boolean unreadOnly)
long findMessageId(Context context, long threadId, long _timestamp, int messageType
void setMessageRead(Context context, long messageId, int messageType)
void deleteMessage(Context context, long messageId, long threadId, int messageType)

this is the method for reading:

SmsMmsMessage getSmsDetails(Context context,
                            long ignoreThreadId, boolean unreadOnly)
{
   String SMS_READ_COLUMN = "read";
   String WHERE_CONDITION = unreadOnly ? SMS_READ_COLUMN + " = 0" : null;
   String SORT_ORDER = "date DESC";
   int count = 0;
   // Log.v(WHERE_CONDITION);
   if (ignoreThreadId > 0) {
      // Log.v("Ignoring sms threadId = " + ignoreThreadId);
      WHERE_CONDITION += " AND thread_id != " + ignoreThreadId;
   }
   Cursor cursor = context.getContentResolver().query(
                      SMS_INBOX_CONTENT_URI,
                      new String[] { "_id", "thread_id", "address", "person", "date", "body" },
                      WHERE_CONDITION,
                      null,
                      SORT_ORDER);
   if (cursor != null) {
      try {
         count = cursor.getCount();
         if (count > 0) {
            cursor.moveToFirst();
            // String[] columns = cursor.getColumnNames();
            // for (int i=0; i<columns.length; i++) {
            // Log.v("columns " + i + ": " + columns[i] + ": " + cursor.getString(i));
            // }                                         
            long messageId = cursor.getLong(0);
            long threadId = cursor.getLong(1);
            String address = cursor.getString(2);
            long contactId = cursor.getLong(3);
            String contactId_string = String.valueOf(contactId);
            long timestamp = cursor.getLong(4);

            String body = cursor.getString(5);                             
            if (!unreadOnly) {
                count = 0;
            }

            SmsMmsMessage smsMessage = new SmsMmsMessage(context, address,
                          contactId_string, body, timestamp,
                          threadId, count, messageId, SmsMmsMessage.MESSAGE_TYPE_SMS);
            return smsMessage;
         }
      } finally {
         cursor.close();
      }
   }               
   return null;
}

For this you need to update your Project Facets setting.

Project (right click) -> Properties -> Project Facets from left navigation.

If it is not open...click on the link, Check the Dynamic Web Module Check Box and select the respective version (Probably 2.4). Click on Apply Button and then Click on OK.

DefaultComboBoxModel dml= new DefaultComboBoxModel();
for (int i = 0; i < <ArrayList>.size(); i++) {
  dml.addElement(<ArrayList>.get(i).getField());
}

<ComboBoxName>.setModel(dml);

Understandable code.Edit<> with type as required.

As noted by S.Lott,

Variable set outside init belong to the class. They're shared by all instances.

Variables created inside init (and all other method functions) and prefaced with self. belong to the object instance.

However, Note that class variables can be accessed via self.<var> until they are masked by an object variable with a similar name This means that reading self.<var> before assigning it a value will return the value of Class.<var> but afterwards it will return obj.<var> . Here is an example

In [20]: class MyClass: 
    ...:     elem = 123 
    ...:  
    ...:     def update(self,i): 
    ...:         self.elem=i  
    ...:     def print(self): 
    ...:         print (MyClass.elem, self.elem) 
    ...:  
    ...: c1 = MyClass()  
    ...: c2 = MyClass() 
    ...: c1.print() 
    ...: c2.print()                                                                                                                                                                                                                                                               
123 123 
123 123 
In [21]: c1.update(1) 
    ...: c2.update(42) 
    ...: c1.print() 
    ...: c2.print()

Second note: Consider slots. They may offer a better way to implement object variables.

You can still use it (mysqli is just another way of communicating with the server, the SQL language itself is expanded, not changed). Prepared statements are safer, though - since you don't need to go through the trouble of properly escaping your values each time. You can leave them as they were, if you want to but the risk of sql piggybacking is reduced if you switch.

Array.join is what you need, but if you like, the friendly people at phpjs.org have created implode for you.

Then some slightly off topic ranting. As @jon_darkstar alreadt pointed out, jQuery is JavaScript and not vice versa. You don't need to know JavaScript to be able to understand how to use jQuery, but it certainly doesn't hurt and once you begin to appreciate reusability or start looking at the bigger picture you absolutely need to learn it.

AFAIK, an Iframe cannot be used that way. You need to point its src attribute to another page.

Here's how to get its body content using plane old javascript. This works with both IE and Firefox.

function getFrameContents(){
   var iFrame =  document.getElementById('id_description_iframe');
   var iFrameBody;
   if ( iFrame.contentDocument ) 
   { // FF
     iFrameBody = iFrame.contentDocument.getElementsByTagName('body')[0];
   }
   else if ( iFrame.contentWindow ) 
   { // IE
     iFrameBody = iFrame.contentWindow.document.getElementsByTagName('body')[0];
   }
    alert(iFrameBody.innerHTML);
 }

In plain C you can use a pointer/size combination in your API.

void doSomething(MyStruct* mystruct, size_t numElements)
{
    for (size_t i = 0; i < numElements; ++i)
    {
        MyStruct current = mystruct[i];
        handleElement(current);
    }
}

Using pointers is the closest to call-by-reference available in C.

1. Choose key
2. API Restriction tab
3. Choose API key
4. Save
5. Choose Application Restriction -> None
6. Save

Try this and it will work like a charm. I was having the same error but this approach did the trick for me:

ssh USER@REMOTE "cat file"|xclip -i

You have to install a Selenium Server (a Hub) and register your remote WebDriver to it. Then, your client will talk to the Hub which will find a matching WebDriver to execute your test.

You can have a look at here for more information.

This is a method that uses a FileUpload control in asp.net:

byte[] buffer = new byte[fu.FileContent.Length];
Stream s = fu.FileContent;
s.Read(buffer, 0, buffer.Length);
//Then save 'buffer' to the varbinary column in your db where you want to store the image.

Not sure about regex, but there is a way for you to do this in Notepad++, although it isn't very flexible.

In the example that you gave, hold Alt and select the column of numbers that you wish to change. Then go to Edit->Column Editor and select the Number to Insert radio button in the window that appears. Then specify your initial number and increment, and hit OK. It should write out the incremented numbers.

Note: this also works with the Multi-editing feature (selecting several locations while maintaining Ctrl key pressed).

This is, however, not anywhere near the flexibility that most people would find useful. Notepad++ is great, but if you want a truly powerful editor that can do things like this with ease, I'd say use Vim.

I had a mismatch between projects: one with multi-byte character set, the other with Unicode. Correcting these to agree on Unicode corrected the problem.

The first way is "more correct", what intention could there be to express? If the code ends, it ends. That's pretty clear, in my opinion.

I don't understand what could possibly be confusing and need clarification. If there's no looping construct being used, then what could possibly happen other than that the function stops executing?

I would be severly annoyed by such a pointless extra return statement at the end of a void function, since it clearly serves no purpose and just makes me feel the original programmer said "I was confused about this, and now you can be too!" which is not very nice.

Problem solved after restarting the tomcat and apache, the tomcat was caching older version of the app.

I know this is old, but the best option is to now use the new placeholder HTML attribute if possible:

<input type="text" id="userid" name="userid" placeholder="Please enter the user ID" />

This will cause the text to show unless a value is entered, eliminating the need to select text or clear inputs.

After insuring that the string "strOutput" has a correct XML structure, you can do this:

Matcher junkMatcher = (Pattern.compile("^([\\W]+)<")).matcher(strOutput);
strOutput = junkMatcher.replaceFirst("<");

In sql 2012 (and maybe as far back as 2005), you should do this:

EXEC AddBrand @BrandName = 'Gucci', @CategoryId = 23

You can truncate the date

SELECT *
FROM Table1
WHERE trunc(field1) = to_Date('2012-01-01','YYY-MM-DD')

Look at the SQL Fiddle for more examples.

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

Often times we are interested in calculating the full significant digits, but for the visual aesthetics, we may want to see only few decimal point when we display the dataframe.

In jupyter-notebook, pandas can utilize the html formatting taking advantage of the method called style.

For the case of just seeing two significant digits of some columns, we can use this code snippet:

Given dataframe

import numpy as np
import pandas as pd

df = pd.DataFrame({'var1': [1.458315, 1.576704, 1.629253, 1.6693310000000001, 1.705139, 1.740447, 1.77598, 1.812037, 1.85313, 1.9439849999999999],
          'var2': [1.500092, 1.6084450000000001, 1.652577, 1.685456, 1.7120959999999998, 1.741961, 1.7708009999999998, 1.7993270000000001, 1.8229819999999999, 1.8684009999999998],
          'var3': [-0.0057090000000000005, -0.005122, -0.0047539999999999995, -0.003525, -0.003134, -0.0012230000000000001, -0.0017230000000000001, -0.002013, -0.001396, 0.005732]})

print(df)
       var1      var2      var3
0  1.458315  1.500092 -0.005709
1  1.576704  1.608445 -0.005122
2  1.629253  1.652577 -0.004754
3  1.669331  1.685456 -0.003525
4  1.705139  1.712096 -0.003134
5  1.740447  1.741961 -0.001223
6  1.775980  1.770801 -0.001723

8  1.853130  1.822982 -0.001396
9  1.943985  1.868401  0.005732

Style to get required format

    df.style.format({'var1': "{:.2f}",'var2': "{:.2f}",'var3': "{:.2%}"})

Gives:

var1    var2    var3
id          
0   1.46    1.50    -0.57%
1   1.58    1.61    -0.51%
2   1.63    1.65    -0.48%
3   1.67    1.69    -0.35%
4   1.71    1.71    -0.31%
5   1.74    1.74    -0.12%
6   1.78    1.77    -0.17%
7   1.81    1.80    -0.20%
8   1.85    1.82    -0.14%
9   1.94    1.87    0.57%

Update

If display command is not found try following:

from IPython.display import display

df_style = df.style.format({'var1': "{:.2f}",'var2': "{:.2f}",'var3': "{:.2%}"})

display(df_style)

Requirements

• To use display command, you need to have installed Ipython in your machine.
• The display command does not work in online python interpreter which do not have IPyton installed such as https://repl.it/languages/python3
• The display command works in jupyter-notebook, jupyter-lab, Google-colab, kaggle-kernels, IBM-watson,Mode-Analytics and many other platforms out of the box, you do not even have to import display from IPython.display

Try it like this:

Replace("\\\"","");

This will replace occurrences of \" with empty string.

Ex:

string t = "\\\"the dog is my friend\\\"";
t = t.Replace("\\\"","");

This will result in:

the dog is my friend

The simplest answer that worked for me was the one mentioned by Prashant, and edited by Bluish.

Go to Start > Configure Tomcat > Startup > Mode = Java Shutdown > Mode = Java

Unfortunately I had(and possibly others) to do this in a different way, I went to the tomcat bin directory and ran the "tomcat7w" application, which is how I changed the configuration.

There I was able to change the startup mode and shutdown mode to Java. Like this:

Step1) Locate tomcat7w:

general location => %TomCatHomeDIR%/bin In my case tomcat was in the xampp folder so my address was:

C:\xampp\tomcat\bin

tomcat7w file location screenshot

Step2) Launch tomcat7w && change the Mode in the Startup and Shutdown tabs

tomcat7w startup tab screenshot

Note >This based on version 7.0.22 that comes standard with XAMPP.

if you add an #include <algorithm> then you can use the for_each function and a lambda function like so:

for_each(data.begin(), data.end(), [](Student *it) 
{
    std::cout<<it->name;
});

you can read more about the algorithm library at https://en.cppreference.com/w/cpp/algorithm

and about lambda functions in cpp at https://docs.microsoft.com/en-us/cpp/cpp/lambda-expressions-in-cpp?view=vs-2019

I -strongly- recommend build your HtmlHelpers. I think that apsx code will be more readable, reliable and durable.

Follow the link; http://msdn.microsoft.com/en-us/library/system.web.mvc.htmlhelper.aspx

Maybe you could use this view, but i'm not sure.

select * from v$database;

But I think It will only show you info about the current db.

Other option, if the db is running in linux... whould be something like this:

SQL>!grep SID $TNS_ADMIN/tnsnames.ora | grep -v PLSExtProc

My reading of the Bash Reference Manual says this stuff is captured in BASH_ARGV, although it talks about "the stack" a lot.

#!/bin/bash

function argv {
    for a in ${BASH_ARGV[*]} ; do
      echo -n "$a "
    done
    echo
}

function f {
    echo f $1 $2 $3
    echo -n f ; argv
}

function g {
    echo g $1 $2 $3
    echo -n g; argv
    f
}

f boo bar baz
g goo gar gaz

Save in f.sh

$ ./f.sh arg0 arg1 arg2
f boo bar baz
farg2 arg1 arg0 
g goo gar gaz
garg2 arg1 arg0

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

use FORMACTION

<input type="submit" value="Delete" formaction="@Url.Action("Delete", new { id = Model.Id })" />

try with following code. make elements with class name page-scroll and keep id name to href of corresponding links

$('a.page-scroll').bind('click', function(event) {
        var $anchor = $(this);
        $('html, body').stop().animate({
            scrollTop: ($($anchor.attr('href')).offset().top - 50)
        }, 1250, 'easeInOutExpo');
        event.preventDefault();
    });

There's an unofficial open-source API for the Android Market you may try to use to get the information you need. Hope this helps.

CGRect rect = label.frame;
rect.size = [label.text sizeWithAttributes:@{NSFontAttributeName : [UIFont fontWithName:label.font.fontName size:label.font.pointSize]}];
label.frame = rect;

If you don't want to use a submission service like Litmus (Litmus is the best, BTW) then you're just going to have to run Outlook 2007 to test your email.

It sounds like you want something a little more automatic (though I'm not sure why), but fortunately Outlook is easy to automate using Visual Basic for Applications (VBA).

You can write a VBA tool that runs from the command line to generate an email, load the email up in Outlook, and even capture a screenshot if you wish. (Presumably this is what the Litmus team does on the backend.)

(BTW, do not attempt to use MS Word to test mail; the renderer is similar but subtle differences in page layout can affect the rendering of your email.)

You didn't say what you're trying to do, but you hinted at it well enough in the comments to the other answer. I think you're probably looking for an auto increment column

create table logins (userid int auto_increment primary key, 
  username varchar(30), password varchar(30));

then no special code is needed on insert. Just

insert into logins (username, password) values ('user','pass');

The MySQL API has functions to tell you what userid was created when you execute this statement in client code.

You absolutely can, I use this approach a lot w/ both JavaScript and PHP.

Field definition:

<input type="hidden" name="foo" value="<?php echo $var;?>" />

Access w/ PHP:

$_GET['foo'] or $_POST['foo']

Also: Don't forget to sanitize your inputs if they are going into a database. Feel free to use my routine: https://github.com/niczak/PHP-Sanitize-Post/blob/master/sanitize.php

Cheers!

Best bet is to copy your folder. Delete the original. Clone the project from github, copy your new files into the new cloned folder, and then try again.

Besides from the multiple line behaviour, the main difference between UITextView and UITextField is that the UITextView does not propose a placeholder. To bypass this limitation, you can use a UITextView with a "fake placeholder."

See this SO question for details: Placeholder in UITextView.

GNU parallel and xargs

These two tools that can make scripts simpler, and also control the maximum number of threads (thread pool). E.g.:

seq 10 | xargs -P4 -I'{}' echo '{}'

or:

seq 10 | parallel -j4  echo '{}'

The solution provided by BBoy works fine. But in my case I had to use

e.Graphics.DrawImage(memoryImage, e.PageBounds);

This will print only the form. When I use MarginBounds it prints the entire screen even if the form is smaller than the monitor screen. PageBounds solved that issue. Thanks to BBoy!

The way you are performing the injection of the property will not work, because the injection is done after the constructor is called.

You need to do one of the following:

Better solution

@Component
public class MyBean {

    private final String prop;

    @Autowired
    public MyBean(@Value("${some.prop}") String prop) {
        this.prop = prop;
        System.out.println("================== " + prop + "================== ");
    }
}

Solution that will work but is less testable and slightly less readable

@Component
public class MyBean {

    @Value("${some.prop}")
    private String prop;

    public MyBean() {

    }

    @PostConstruct
    public void init() {
        System.out.println("================== " + prop + "================== ");
    }
}

Also note that is not Spring Boot specific but applies to any Spring application

You can use

 moment("15", "hh").format('LT') 

to convert the time to 12 hours format like this 3:00 PM

function foo() {_x000D_
  function bar() {_x000D_
    console.trace("Tracing is Done here");_x000D_
  }_x000D_
  bar();_x000D_
}_x000D_
_x000D_
foo();

console.log(console); //to print console object_x000D_
console.clear('console.clear'); //to clear console_x000D_
console.log('console.log'); //to print log message_x000D_
console.info('console.info'); //to print log message _x000D_
console.debug('console.debug'); //to debug message_x000D_
console.warn('console.warn'); //to print Warning_x000D_
console.error('console.error'); //to print Error_x000D_
console.table(["car", "fruits", "color"]);//to print data in table structure_x000D_
console.assert('console.assert'); //to print Error_x000D_
console.dir({"name":"test"});//to print object_x000D_
console.dirxml({"name":"test"});//to print object as xml formate

To Print Error:- console.error('x=%d', x);

console.log("This is the outer level");_x000D_
console.group();_x000D_
console.log("Level 2");_x000D_
console.group();_x000D_
console.log("Level 3");_x000D_
console.warn("More of level 3");_x000D_
console.groupEnd();_x000D_
console.log("Back to level 2");_x000D_
console.groupEnd();_x000D_
console.log("Back to the outer level");

I am pretty new to all of this, but I found that if the script is started via CScript.exe (console scripting host) there is no window popping up on exec(): so when running:

cscript myscript.vbs //nologo

any .Exec() calls in the myscript.vbs do not open an extra window, meaning that you can use the first variant of your original solution (using exec).

(Note that the two forward slashes in the above code are intentional, see cscript /?)

btnTest_Click(null, null);

Provided that the method isn't using either of these parameters (it's very common not to.)

To be honest though this is icky. If you have code that needs to be called you should follow the following convention:

protected void btnTest_Click(object sender, EventArgs e)
{
   SomeSub();
}

protected void SomeOtherFunctionThatNeedsToCallTheCode()
{
   SomeSub();
}

protected void SomeSub()
{
   // ...
}

There is a built-in way to format LocalDate in Joda library

import org.joda.time.LocalDate;

LocalDate localDate = LocalDate.now();
String dateFormat = "MM/dd/yyyy";
localDate.toString(dateFormat);

In case you don't have it already - add this to the build.gradle:

implementation 'joda-time:joda-time:2.9.5'

Happy coding! :)

You should create table2 first.

insert into table2(field1,field2,...)
select field1,field2,....
from table1
where condition;

We have tried custom search box with the pasted snippet. This code will useful for all kind of TextFiled decoration in Flutter. Hope this snippet will helpful for others.

You can try this code to get HTTP status code from WebException. It works in Silverlight too because SL does not have WebExceptionStatus.ProtocolError defined.

HttpStatusCode GetHttpStatusCode(WebException we)
{
    if (we.Response is HttpWebResponse)
    {
        HttpWebResponse response = (HttpWebResponse)we.Response;
        return response.StatusCode;
    }
    return null;
}

I had hard time figuring out the actual reason, it happens when we dont read properly from file. you need to open file and read with readlines() method as below:

with open('/content/drive/pre-processed-users1.1.tsv') as f:
    file=f.readlines()

It corrects the formatted output

Looks file you use the .mkdirs() method on a File object: http://www.roseindia.net/java/beginners/java-create-directory.shtml

// Create a directory; all non-existent ancestor directories are
// automatically created
success = (new File("../potentially/long/pathname/without/all/dirs")).mkdirs();
if (!success) {
    // Directory creation failed
}

Why not Process.Start(@"c:\test");?

WAMP USERS:

1) Go to C:\wamp\apps\phpmyadmin

2) Open config.inc

3) Add $cfg['ExecTimeLimit'] = ’3600'; to the file.

4) Save the file and restart the server.

This file overwrites the php.ini and will work for you!

use center right as the position then add a transparent border to offset it?

List<string> myCollection = new List<string>()
{
    "Bob", "Bob","Alex", "Abdi", "Abdi", "Bob", "Alex", "Bob","Abdi"
};

myCollection.Sort();
foreach (var name in myCollection.Distinct())
{
    Console.WriteLine(name + " " + myCollection.Count(x=> x == name));
}

output: Abdi 3 Alex 2 Bob 4

To solve this problem I had to install the package with the missing system image using SDK Manager.exe (in "C:\Program Files (x86)\Android\android-sdk"). I had noticed that the system image I needed ("android-23") was missing in "C:\Program Files (x86)\Android\android-sdk\system-images".

After running SDK Manager.exe and installing the appropriate packages I could run the emulator in Android Studio.

Here's the solution that worked for me:

Why should you learn Python Programming Language?

Python offers a stepping stone into the world of programming. Even though Python Programming Language has been around for 25 years, it is still rising in popularity. Some of the biggest advantage of Python are it's

• Easy to Read & Easy to Learn
• Very productive or small as well as big projects
• Big libraries for many things

What is Python Programming Language used for?

As a general purpose programming language, Python can be used for multiple things. Python can be easily used for small, large, online and offline projects. The best options for utilizing Python are web development, simple scripting and data analysis. Below are a few examples of what Python will let you do:

Web Development:

You can use Python to create web applications on many levels of complexity. There are many excellent Python web frameworks including, Pyramid, Django and Flask, to name a few.

Data Analysis:

Python is the leading language of choice for many data scientists. Python has grown in popularity, within this field, due to its excellent libraries including; NumPy and Pandas and its superb libraries for data visualisation like Matplotlib and Seaborn.

Machine Learning:

What if you could predict customer satisfaction or analyse what factors will affect household pricing or to predict stocks over the next few days, based on previous years data? There are many wonderful libraries implementing machine learning algorithms such as Scikit-Learn, NLTK and TensorFlow.

Computer Vision:

You can do many interesting things such as Face detection, Color detection while using Opencv and Python.

Internet Of Things With Raspberry Pi:

Raspberry Pi is a very tiny and affordable computer which was developed for education and has gained enormous popularity among hobbyists with do-it-yourself hardware and automation. You can even build a robot and automate your entire home. Raspberry Pi can be used as the brain for your robot in order to perform various actions and/or react to the environment. The coding on a Raspberry Pi can be performed using Python. The Possibilities are endless!

Game Development:

Create a video game using module Pygame. Basically, you use Python to write the logic of the game. PyGame applications can run on Android devices.

Web Scraping:

If you need to grab data from a website but the site does not have an API to expose data, use Python to scraping data.

Writing Scripts:

If you're doing something manually and want to automate repetitive stuff, such as emails, it's not difficult to automate once you know the basics of this language.

Browser Automation:

Perform some neat things such as opening a browser and posting a Facebook status, you can do it with Selenium with Python.

GUI Development:

Build a GUI application (desktop app) using Python modules Tkinter, PyQt to support it.

Rapid Prototyping:

Python has libraries for just about everything. Use it to quickly built a (lower-performance, often less powerful) prototype. Python is also great for validating ideas or products for established companies and start-ups alike.

Python can be used in so many different projects. If you're a programmer looking for a new language, you want one that is growing in popularity. As a newcomer to programming, Python is the perfect choice for learning quickly and easily.

You can use flex-grow: 1. The default value is 0 and it will cause the text-align: center looks like left.

void    QWidget::setWindowTitle ( const QString & )

EDIT: If you are using QtDesigner, on the property tab, there is an editable property called windowTitle which can be found under the QWidget section. The property tab can usually be found on the lower right part of the designer window.

SELECT A.ABC_ID, A.VAL FROM A WHERE NOT EXISTS 
   (SELECT * FROM B WHERE B.ABC_ID = A.ABC_ID AND B.VAL = A.VAL)

or

SELECT A.ABC_ID, A.VAL FROM A WHERE VAL NOT IN 
    (SELECT VAL FROM B WHERE B.ABC_ID = A.ABC_ID)

or

SELECT A.ABC_ID, A.VAL LEFT OUTER JOIN B 
    ON A.ABC_ID = B.ABC_ID AND A.VAL = B.VAL FROM A WHERE B.VAL IS NULL

Please note that these queries do not require that ABC_ID be in table B at all. I think that does what you want.

You can try c#

public string ProcessMyDataItem(object myValue)
 {
  if (myValue == null)
   {
   return "0 %"";
  }
   else
  {
     if(Convert.ToInt32(myValue) < 50)
       return "0";
     else
      return myValue.ToString() + "%";
  }

 }

asp

 <div class="tooltip" style="display: none">                                                                  
      <div style="text-align: center; font-weight: normal">
   Value =<%# ProcessMyDataItem(Eval("Percentage")) %> </div>
 </div>

Put in the URL bar and then click enter:

javascript:alert(document.title);

You can select and copy the text from the alert depending on the website and the web browser you are using.

My case it solved i was using

@Html.DropDownList(model => model.TypeId ...)  

using

@Html.DropDownListFor(model => model.TypeId ...) 

will solve it

You can use the simple soupparser from lxml

Example:

from lxml.html.soupparser import fromstring

tree = fromstring("<a>Find me!</a>")
print tree.xpath("//a/text()")

In a modern two-tier architecture, the server holds both the application and the data. The application resides on the server rather than the client, probably because the server will have more processing power and disk space than the PC.

In a three-tier architecture, the data and applications are split onto seperate servers, with the server-side distributed between a database server and an application server. The client is a front end, simply requesting and displaying data. Reason being that each server will be dedicated to processing either data or application requests, hence a more manageable system and less contention for resources will occur.

You can refer to Difference between three tier vs. n-tier

Inspired by Andrie's answer, you could use identical and avoid any attribute problems by using the fact that it is the empty set of that class of object and combine it with an element of that class:

attr(a, "foo") <- "bar"

identical(1L, c(a, 1L))
#> [1] TRUE

Or more generally:

is.empty <- function(x, mode = NULL){
    if (is.null(mode)) mode <- class(x)
    identical(vector(mode, 1), c(x, vector(class(x), 1)))
}

b <- numeric(0)

is.empty(a)
#> [1] TRUE
is.empty(a,"numeric")
#> [1] FALSE
is.empty(b)
#> [1] TRUE
is.empty(b,"integer")
#> [1] FALSE

System.IO.Path.GetTempPath()

The path specified by the TMP environment variable. The path specified by the TEMP environment variable. The path specified by the USERPROFILE environment variable. The Windows directory.

Another workaround would be to initiate a modal window containing its own form

NOTE: If you have access to C# 5.0 Unleashed, read the "Limitations on Plain Use of Delegates" in Chapter 18 titled "Events" to understand better the differences between the two.

It always helps me to have a simple, concrete example. So here's one for the community. First I show how you can use delegates alone to do what Events do for us. Then I show how the same solution would work with an instance of EventHandler. And then I explain why we DON'T want to do what I explain in the first example. This post was inspired by an article by John Skeet.

Example 1: Using public delegate

Suppose I have a WinForms app with a single drop-down box. The drop-down is bound to an List<Person>. Where Person has properties of Id, Name, NickName, HairColor. On the main form is a custom user control that shows the properties of that person. When someone selects a person in the drop-down the labels in the user control update to show the properties of the person selected.

Here is how that works. We have three files that help us put this together:

• Mediator.cs -- static class holds the delegates
• Form1.cs -- main form
• DetailView.cs -- user control shows all details

Here is the relevant code for each of the classes:

class Mediator
{
    public delegate void PersonChangedDelegate(Person p); //delegate type definition
    public static PersonChangedDelegate PersonChangedDel; //delegate instance. Detail view will "subscribe" to this.
    public static void OnPersonChanged(Person p) //Form1 will call this when the drop-down changes.
    {
        if (PersonChangedDel != null)
        {
            PersonChangedDel(p);
        }
    }
}

Here is our user control:

public partial class DetailView : UserControl
{
    public DetailView()
    {
        InitializeComponent();
        Mediator.PersonChangedDel += DetailView_PersonChanged;
    }

    void DetailView_PersonChanged(Person p)
    {
        BindData(p);
    }

    public void BindData(Person p)
    {
        lblPersonHairColor.Text = p.HairColor;
        lblPersonId.Text = p.IdPerson.ToString();
        lblPersonName.Text = p.Name;
        lblPersonNickName.Text = p.NickName;

    }
}

Finally we have the following code in our Form1.cs. Here we are Calling OnPersonChanged, which calls any code subscribed to the delegate.

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    Mediator.OnPersonChanged((Person)comboBox1.SelectedItem); //Call the mediator's OnPersonChanged method. This will in turn call all the methods assigned (i.e. subscribed to) to the delegate -- in this case `DetailView_PersonChanged`.
}

Ok. So that's how you would get this working without using events and just using delegates. We just put a public delegate into a class -- you can make it static or a singleton, or whatever. Great.

BUT, BUT, BUT, we do not want to do what I just described above. Because public fields are bad for many, many reason. So what are our options? As John Skeet describes, here are our options:

1. A public delegate variable (this is what we just did above. don't do this. i just told you above why it's bad)
2. Put the delegate into a property with a get/set (problem here is that subscribers could override each other -- so we could subscribe a bunch of methods to the delegate and then we could accidentally say PersonChangedDel = null, wiping out all of the other subscriptions. The other problem that remains here is that since the users have access to the delegate, they can invoke the targets in the invocation list -- we don't want external users having access to when to raise our events.
3. A delegate variable with AddXXXHandler and RemoveXXXHandler methods

This third option is essentially what an event gives us. When we declare an EventHandler, it gives us access to a delegate -- not publicly, not as a property, but as this thing we call an event that has just add/remove accessors.

Let's see what the same program looks like, but now using an Event instead of the public delegate (I've also changed our Mediator to a singleton):

Example 2: With EventHandler instead of a public delegate

Mediator:

class Mediator
{

    private static readonly Mediator _Instance = new Mediator();

    private Mediator() { }

    public static Mediator GetInstance()
    {
        return _Instance;
    }

    public event EventHandler<PersonChangedEventArgs> PersonChanged; //this is just a property we expose to add items to the delegate.

    public void OnPersonChanged(object sender, Person p)
    {
        var personChangedDelegate = PersonChanged as EventHandler<PersonChangedEventArgs>;
        if (personChangedDelegate != null)
        {
            personChangedDelegate(sender, new PersonChangedEventArgs() { Person = p });
        }
    }
}

Notice that if you F12 on the EventHandler, it will show you the definition is just a generic-ified delegate with the extra "sender" object:

public delegate void EventHandler<TEventArgs>(object sender, TEventArgs e);

The User Control:

public partial class DetailView : UserControl
{
    public DetailView()
    {
        InitializeComponent();
        Mediator.GetInstance().PersonChanged += DetailView_PersonChanged;
    }

    void DetailView_PersonChanged(object sender, PersonChangedEventArgs e)
    {
        BindData(e.Person);
    }

    public void BindData(Person p)
    {
        lblPersonHairColor.Text = p.HairColor;
        lblPersonId.Text = p.IdPerson.ToString();
        lblPersonName.Text = p.Name;
        lblPersonNickName.Text = p.NickName;

    }
}

Finally, here's the Form1.cs code:

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
        Mediator.GetInstance().OnPersonChanged(this, (Person)comboBox1.SelectedItem);
}

Because the EventHandler wants and EventArgs as a parameter, I created this class with just a single property in it:

class PersonChangedEventArgs
{
    public Person Person { get; set; }
}

Hopefully that shows you a bit about why we have events and how they are different -- but functionally the same -- as delegates.

Upstream Called Harmful

There is, alas, another use of "upstream" that the other answers here are not getting at, namely to refer to the parent-child relationship of commits within a repo. Scott Chacon in the Pro Git book is particularly prone to this, and the results are unfortunate. Do not imitate this way of speaking.

For example, he says of a merge resulting a fast-forward that this happens because

the commit pointed to by the branch you merged in was directly upstream of the commit you’re on

He wants to say that commit B is the only child of the only child of ... of the only child of commit A, so to merge B into A it is sufficient to move the ref A to point to commit B. Why this direction should be called "upstream" rather than "downstream", or why the geometry of such a pure straight-line graph should be described "directly upstream", is completely unclear and probably arbitrary. (The man page for git-merge does a far better job of explaining this relationship when it says that "the current branch head is an ancestor of the named commit." That is the sort of thing Chacon should have said.)

Indeed, Chacon himself appears to use "downstream" later to mean exactly the same thing, when he speaks of rewriting all child commits of a deleted commit:

You must rewrite all the commits downstream from 6df76 to fully remove this file from your Git history

Basically he seems not to have any clear idea what he means by "upstream" and "downstream" when referring to the history of commits over time. This use is informal, then, and not to be encouraged, as it is just confusing.

It is perfectly clear that every commit (except one) has at least one parent, and that parents of parents are thus ancestors; and in the other direction, commits have children and descendants. That's accepted terminology, and describes the directionality of the graph unambiguously, so that's the way to talk when you want to describe how commits relate to one another within the graph geometry of a repo. Do not use "upstream" or "downstream" loosely in this situation.

[Additional note: I've been thinking about the relationship between the first Chacon sentence I cite above and the git-merge man page, and it occurs to me that the former may be based on a misunderstanding of the latter. The man page does go on to describe a situation where the use of "upstream" is legitimate: fast-forwarding often happens when "you are tracking an upstream repository, you have committed no local changes, and now you want to update to a newer upstream revision." So perhaps Chacon used "upstream" because he saw it here in the man page. But in the man page there is a remote repository; there is no remote repository in Chacon's cited example of fast-forwarding, just a couple of locally created branches.]

Resolution for 404 Forbidden in recent .Net 4.7 MVC/webform pplication hosting in Azure VM We need to install the .Net 4.7 and extensibilty and development in server role other than the .Net 4.7/version feature as below: This might have been alreday activated .Net Activated feature

We need to also add the below under IIS webserver role-> Application Development -> select the .Net version as below Image to Activate the requited Role under IIS webserver Role Server Role Activation under application Development

Yes this is possible. It is not enough you just copy the .frm files to the to the databse folder but you also need to copy the ib_logfiles and ibdata file into your data folder. I have just copy the .frm files and copy those files and just restart the server and my database is restored.

After copying the above files execute the following command -

sudo chown -R mysql:mysql /var/lib/mysql

The above command will change the file owner under mysql and it's folder to MySql user. Which is important for mysql to read the .frm and ibdata files.

The following would work:

myarray: [
  String1, String2, String3,
  String4, String5, String5, String7
]

I tested it using the snakeyaml implementation, I am not sure about other implementations though.

It may not be the Pythonic way, but I generally use a list with the join function for writing a long string, like SQL queries:

query = " ".join([
    'SELECT * FROM "TableName"',
    'WHERE "SomeColumn1"=VALUE',
    'ORDER BY "SomeColumn2"',
    'LIMIT 5;'
])

As we know jQuery validate plugin invalidates Select field when it has blank value. Why don't we set its value to blank when required.

Yes, you can validate select field with some predefined value.

$("#everything").validate({
    rules: {
        select_field:{
            required: {
                depends: function(element){
                    if('none' == $('#select_field').val()){
                        //Set predefined value to blank.
                        $('#select_field').val('');
                    }
                    return true;
                }
            }
        }
    }
});

We can set blank value for select field but in some case we can't. For Ex: using a function that generates Dropdown field for you and you don't have control over it.

I hope it helps as it helps me.

I use format, Number, 2 decimal places & tick ' use 1000 separater ', then go to 'File', 'Options', 'Advanced', scroll down to 'When calculating this workbook' and tick 'set precision as displayed'. You get an error message about losing accuracy, that's good as it means it is rounding to 2 decimal places. So much better than bothering with adding a needless ROUND function.

Run Spring Boot app using Maven

You can also use Maven plugin to run your Spring Boot app. Use the below example to run your Spring Boot app with Maven plugin:

mvn spring-boot:run

Run Spring Boot App with Gradle

And if you use Gradle you can run the Spring Boot app with the following command:

gradle bootRun

System.Diagnostics.Process.Start("shutdown", "/s /t 0")

Should work.

For restart, it's /r

This will restart the PC box directly and cleanly, with NO dialogs.

Your error is posted in the official documentation. You can read this article.

I have copied the reason for you (and hyperlinked the URLs) from that article:

This will happen if the administrator has not created a PostgreSQL user account for you. (PostgreSQL user accounts are distinct from operating system user accounts.) If you are the administrator, see Chapter 20 for help creating accounts. You will need to become the operating system user under which PostgreSQL was installed (usually postgres) to create the first user account. It could also be that you were assigned a PostgreSQL user name that is different from your operating system user name; in that case you need to use the -U switch or set the PGUSER environment variable to specify your PostgreSQL user name

For your purposes, you can do:

1) Create a PostgreSQL user account:

sudo -u postgres createuser tom -d -P

(the -P option to set a password; the -d option for allowing the creation of database for your username 'tom'. Note that 'tom' is your operating system username. That way, you can execute PostgreSQL commands without sudoing.)

2) Now you should be able to execute createdb and other PostgreSQL commands.

We can set layout gravity on any view like below way-

myView = findViewById(R.id.myView);
myView.setGravity(Gravity.CENTER_VERTICAL|Gravity.RIGHT);
 or
myView.setGravity(Gravity.BOTTOM);

This is equilent to below xml code

<...
 android:gravity="center_vertical|right"
 ...
 .../>

You can concatenate the array values with implode and a separator of | and then use preg_match to search for the value.

Here is the solution I came up with ...

$emails = array('@gmail', '@hotmail', '@outlook', '@live', '@msn', '@yahoo', '@ymail', '@aol');
$emails = implode('|', $emails);

if(!preg_match("/$emails/i", $email)){
 // do something
}

I’ve run into the need while running on PhpStorm on my Mac. Follow the orange text.

How about this below... this will produce the really random values:

function getRandomStrings(length) {
  const value = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
  const randoms = [];
  for(let i=0; i < length; i++) {
     randoms.push(value[Math.floor(Math.random()*value.length)]);
  }
  return randoms.join('');
}

But if you looking for a shorter syntax one in ES6:

const getRandomStrings = length => Math.random().toString(36).substr(-length);

Check string using single quotes

Ex. $_POST['group1'] == 'add'

Use character classes: [ \t]

this is a kind of brief solution,that add a row to local exclude file.

Or:

• find().
• Selector context.

Good to learn from the find() documentation:

The .find() and .children() methods are similar, except that the latter only travels a single level down the DOM tree.

Here is a simple example of adding an image to a JFrame:

frame.add(new JLabel(new ImageIcon("Path/To/Your/Image.png")));

If you are using post as a model (without dependency injection), you can also do:

$posts = Post::orderBy('id', 'DESC')->get();

Here is one way to do it:

>>> n = 46
>>> (n + 9) // 10 * 10
50

You need to repartition the Dataframe in a single partition and then define the format, path and other parameter to the file in Unix file system format and here you go,

df.repartition(1).write.format('com.databricks.spark.csv').save("/path/to/file/myfile.csv",header = 'true')

Read more about the repartition function Read more about the save function

However, repartition is a costly function and toPandas() is worst. Try using .coalesce(1) instead of .repartition(1) in previous syntax for better performance.

Read more on repartition vs coalesce functions.

Your collection class could have a method that returns a collection (a sublist) based on criteria passed in to define the filter. Build a new collection with the foreach loop and pass it out.

Or, have the method and loop modify the existing collection by setting a "filtered" or "active" flag (property). This one could work but could also cause poblems in multithreaded code. If other objects deped on the contents of the collection this is either good or bad depending of how you use the data.

Definitely not the most correct way, but if you just need a quick solution to get the date without the time and you do not wish to use a third party library this should do

    Date db = db.substring(0, 10) + db.substring(23,28);

I only needed the date for visual purposes and couldn't Joda so I substringed.

If there are no credentials provided in the request headers, the following is the minimum response required for IE to prompt the user for credentials and resubmit the request.

Response.Clear();
Response.StatusCode = (Int32)HttpStatusCode.Unauthorized;
Response.AddHeader("WWW-Authenticate", "Basic");

Just use the following regular expression:

(?<=My cow\s).*?(?=\smilk)

This post talks about how to setup a private registry

• make sure couchdb is installed in your system

• Replicating npmjs.org use the following command

  curl -X POST http://127.0.0.1:5984/_replicate -d '{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry", "continuous":true, "create_target":true}' -H "Content-Type: application/json"
  

Note there is "continuous":true in the command, this utilises CouchDB’s _changes API and will pull any new changes when this API is notified.

If you ever want to stop these replications, you can easily add "cancel":true. Then the script would be

    curl -X POST http://127.0.0.1:5984/_replicate -d '{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry", "continuous":true, "create_target":true, "cancel":true}' -H "Content-Type: application/json"

Then go to npmjs.org readme to install npm (make sure nodejs and git is installed). Blow is all the steps

git clone git://github.com/isaacs/npmjs.org.git
cd npmjs.org
sudo npm install -g couchapp 
npm install couchapp 
npm install semver 
couchapp push registry/app.js http://localhost:5984/registry 
couchapp push www/app.js http://localhost:5984/registry 

I know this question is old and already has an accepted answer, but I want to offer a few examples (hoping it'll be useful to someone).

As far as I know old ASCII characters took one byte per character.

Right. Actually, since ASCII is a 7-bit encoding, it supports 128 codes (95 of which are printable), so it only uses half a byte (if that makes any sense).

How many bytes does a Unicode character require?

Unicode just maps characters to codepoints. It doesn't define how to encode them. A text file does not contain Unicode characters, but bytes/octets that may represent Unicode characters.

I assume that one Unicode character can contain every possible character from any language - am I correct?

No. But almost. So basically yes. But still no.

So how many bytes does it need per character?

Same as your 2nd question.

And what do UTF-7, UTF-6, UTF-16 etc mean? Are they some kind Unicode versions?

No, those are encodings. They define how bytes/octets should represent Unicode characters.

A couple of examples. If some of those cannot be displayed in your browser (probably because the font doesn't support them), go to http://codepoints.net/U+1F6AA (replace 1F6AA with the codepoint in hex) to see an image.

Okay I'm getting carried away...

Fun facts:

• If you're looking for a specific character, you can copy&paste it on http://codepoints.net/.
• I wasted a lot of time on this useless list (but it's sorted!).
• MySQL has a charset called "utf8" which actually does not support characters longer than 3 bytes. So you can't insert a pile of poo, the field will be silently truncated. Use "utf8mb4" instead.
• There's a snowman test page (unicodesnowmanforyou.com).

You can "abort" a task by running it on a thread you control and aborting that thread. This causes the task to complete in a faulted state with a ThreadAbortException. You can control thread creation with a custom task scheduler, as described in this answer. Note that the caveat about aborting a thread applies.

(If you don't ensure the task is created on its own thread, aborting it would abort either a thread-pool thread or the thread initiating the task, neither of which you typically want to do.)

I prefer not to alter the df.

An option is to retrieve the index of the start and end dates:

import numpy as np   
import pandas as pd

#Dummy DataFrame
df = pd.DataFrame(np.random.random((30, 3)))
df['date'] = pd.date_range('2017-1-1', periods=30, freq='D')

#Get the index of the start and end dates respectively
start = df[df['date']=='2017-01-07'].index[0]
end = df[df['date']=='2017-01-14'].index[0]

#Show the sliced df (from 2017-01-07 to 2017-01-14)
df.loc[start:end]

which results in:

     0   1   2       date
6  0.5 0.8 0.8 2017-01-07
7  0.0 0.7 0.3 2017-01-08
8  0.8 0.9 0.0 2017-01-09
9  0.0 0.2 1.0 2017-01-10
10 0.6 0.1 0.9 2017-01-11
11 0.5 0.3 0.9 2017-01-12
12 0.5 0.4 0.3 2017-01-13
13 0.4 0.9 0.9 2017-01-14
