You can do like this, to get the currently selected value:

$('#myDropdownID').val();

& to get the currently selected text:

$('#myDropdownID:selected').text();

Because Convert.ToInt32 rounds:

Return Value: rounded to the nearest 32-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.

...while the cast truncates:

When you convert from a double or float value to an integral type, the value is truncated.

Update: See Jeppe Stig Nielsen's comment below for additional differences (which however do not come into play if score is a real number as is the case here).

Use Attribute Equals Selector

$('.slide-link[data-slide="0"]').addClass('active');

Fiddle Demo

.find()

it works down the tree

Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

Here is another solution:

for(String serverId : serverIds) {
   sb.append(",");
   sb.append(serverId); 
}

String resultingString = "";
if ( sb.length() > 1 ) {
    resultingString = sb.substring(1);
}

try this code I think it is more optimal.

HeaderRow is used to repeat the header of the table for each new page automatically

        BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
        iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

        PdfPTable table = new PdfPTable(10) { HorizontalAlignment = Element.ALIGN_CENTER, WidthPercentage = 100, HeaderRows = 2 };
        table.SetWidths(new float[] { 2f, 6f, 6f, 3f, 5f, 8f, 5f, 5f, 5f, 5f });
        table.AddCell(new PdfPCell(new Phrase("SER.\nNO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("TYPE OF SHIPPING", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("ORDER NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("QTY.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISCHARGE PPORT", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESCRIPTION OF GOODS", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("LINE DOC. RECL DATE", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CLEARANCE DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CUSTOM PERMIT NO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISPATCH DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("AWB/BL NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("COMPLEX NAME", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("G. W. Kgs.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESTINATION", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("OWNER DOC. RECL DATE", times)) { GrayFill = 0.95f });

This: "\0" is a string, not a character. A character uses single quotes, like '\0'.

suppose you want to write a url to fetch some order, you can say

www.mydomain.com/order/123

where 123 is orderId.

So now the url you will use in spring mvc controller would look like

/order/{orderId}

Now order id can be declared a path variable

@RequestMapping(value = " /order/{orderId}", method=RequestMethod.GET)
public String getOrder(@PathVariable String orderId){
//fetch order
}

if you use url www.mydomain.com/order/123, then orderId variable will be populated by value 123 by spring

Also note that PathVariable differs from requestParam as pathVariable is part of URL. The same url using request param would look like www.mydomain.com/order?orderId=123

I recently submitted an app to Apple's App Store. My app was built using iOS 12, Xcode 10, and Swift 4.2. My app uses Google AdMob for the sole purpose of showing Interstitial Ads. When prompted these question, this is what I did:

1) Does this app use the Advertising Identifier (IDFA)? ANSWER: YES

a) Serve advertisements within the app - CHECKED

b) Attribute this app ... - NOT CHECKED

c) Attribute an action ... - NOT CHECKED

I, (my name), confirm that this app ... - CHECKED

My app was accepted and "Ready for Sale" in less than 24 hrs.

This code works fine. There is definitely some other problem:

>>> str1 = "3158 reviews"
>>> print (re.findall('\d+', str1 ))
['3158']

String DataString=DateFormat.getDateInstance(DateFormat.SHORT).format(Calendar.getInstance().getTime());

To get the short date formatted String in the localised format of the unit.

I can't understand why so many answers are hardcoded date and time formats when the OS/Java supplies correct localisation of Dates and time? Isn't it better always use the formats of the unit than of the programmer?

It also supplies the reading of dates in localised formats:

    DateFormat format = DateFormat.getDateInstance(DateFormat.SHORT);
    Date date=null;
    try {
        date = format.parse(DateString);
    }
    catch(ParseException e) {
    }

Then it is up to the user setting the format to show the dates and time and not you? Regardless languages etc there are different formats in different countries with the same language.

Pinal Dave has a nice article with some examples on how to add trailing 0s to SQL numbers.

One way is using the RIGHT function, which would make the statement something like the following:

SELECT RIGHT('00' + CAST(DATEPART(mm, @date) AS varchar(2)), 2)

__toString method or (string) cast

$string=(string)$variable;  //force make string 

you can treat an object as a string

class Foo
{

  public function __toString()
  {
     return "foo";
  }

}

echo new Foo(); //foo

also, have another trick, i assume i have int variable i want to make string it

$string=''.$intvariable;

Okay, let's re-iterate...

The actual question (and an excellent one at that)

"What does 'run as admin' do that being a member of the administrators group does not?"

(Answer)1. It allows you to call on administrator rights while under a user session.

Note: The question is wrongly put; one is a command and the other is a group object to apply policies.

Open a command prompt and type runas /?.

This will list all the switches the runas command line can use.

As for the Administrators Group this is based on GPEDIT or SECPOL and whether or not a Domain administrator is present or not or a network is present or not.

Usually these things will apply restrictions on computers that the administrators group is not affected by.

The question should be

What does runas admin do that run as user does not?

OR

What does the Administrator group do that a customized user group can't?

You are mixing apples and oranges.

style is accordingly vis css. An example

<h1 class="mynotsoboldtitle">Im not bold</h1>
<style>
.mynotsoboldtitle { font-weight:normal; }
</style>

After deleting I'm also using VACUUM command. So for full TRUNCATE equivalent I use this code:

DELETE FROM <table>;
UPDATE SQLITE_SEQUENCE SET seq = 0 WHERE name = '<table>';
VACUUM;

Deleting isn't working for me for reset Auto Increment

DELETE FROM "sqlite_sequence" WHERE "name"='<table>';

To read more about VACUUM you can go here: https://blogs.gnome.org/jnelson/2015/01/06/sqlite-vacuum-and-auto_vacuum/

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

Use Date.Now instead of DateTime.Now

You can do like this:

$q="SELECT * FROM projects WHERE Year(Date) = '$year' and Month(Date) = '$month'";

With a = subprocess.Popen("cdrecord --help",stdout = subprocess.PIPE) , you need to either use a list or use shell=True;

Either of these will work. The former is preferable.

a = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE)

a = subprocess.Popen('cdrecord --help', shell=True, stdout=subprocess.PIPE)

Also, instead of using Popen.stdout.read/Popen.stderr.read, you should use .communicate() (refer to the subprocess documentation for why).

proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()

Do you mean Delegate.Invoke/BeginInvoke or Control.Invoke/BeginInvoke?

• Delegate.Invoke: Executes synchronously, on the same thread.
• Delegate.BeginInvoke: Executes asynchronously, on a threadpool thread.
• Control.Invoke: Executes on the UI thread, but calling thread waits for completion before continuing.
• Control.BeginInvoke: Executes on the UI thread, and calling thread doesn't wait for completion.

Tim's answer mentions when you might want to use BeginInvoke - although it was mostly geared towards Delegate.BeginInvoke, I suspect.

For Windows Forms apps, I would suggest that you should usually use BeginInvoke. That way you don't need to worry about deadlock, for example - but you need to understand that the UI may not have been updated by the time you next look at it! In particular, you shouldn't modify data which the UI thread might be about to use for display purposes. For example, if you have a Person with FirstName and LastName properties, and you did:

person.FirstName = "Kevin"; // person is a shared reference
person.LastName = "Spacey";
control.BeginInvoke(UpdateName);
person.FirstName = "Keyser";
person.LastName = "Soze";

Then the UI may well end up displaying "Keyser Spacey". (There's an outside chance it could display "Kevin Soze" but only through the weirdness of the memory model.)

Unless you have this sort of issue, however, Control.BeginInvoke is easier to get right, and will avoid your background thread from having to wait for no good reason. Note that the Windows Forms team has guaranteed that you can use Control.BeginInvoke in a "fire and forget" manner - i.e. without ever calling EndInvoke. This is not true of async calls in general: normally every BeginXXX should have a corresponding EndXXX call, usually in the callback.

You can try this:

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});

Easiest way to find duplicate values in a JavaScript array

According to the documentation:

$validator = Validator::make($request->all(), [
    'file' => 'max:500000',
]);

The value is in kilobytes. I.e. max:10240 = max 10 MB.

A servlet at its very core is a java class; which can handle HTTP requests. Typically the internal nitty-gritty of reading a HTTP request and response over the wire is taken care of by the containers like Tomcat. This is done so that as a server side developer you can focus on what to do with the HTTP request and responses and not bother about dealing with code that deals with networking etc. The container will take care of things like wrapping the whole thing in a HTTP response object and send it over to the client (say a browser).

Now the next logical question to ask is who decides what is a container supposed to do? And the answer is; In Java world at least It is guided (note I did not use the word controlled) by specifications. For example Servlet specifications (See resource 2) dictates what a servlet must be able to do. So if you can write an implementation for the specification, congratulations you just created a container (Technically containers like Tomcat also implement other specifications and do tricky stuff like custom class loaders etc but you get the idea).

Assuming you have a container, your servlets are now java classes whose lifecycle will be maintained by the container but their reaction to incoming HTTP requests will be decided by you. You do that by writing what-you-want-to-do in the pre-defined methods like init(), doGet(), doPost() etc. Look at Resource 3.

Here is a fun exercise for you. Create a simple servlet like in Resource 3 and write a few System.out.println() statements in it's constructor method (Yes you can have a constructor of a servlet), init(), doGet(), doPost() methods and run the servlet in tomcat. See the console logs and tomcat logs.

Hope this helps, happy learning.

Resources

1. Look how the HTTP servlet looks here(Tomcat example).

2. Servlet Specification.

3. Simple Servlet example.

4. Start reading the book online/PDF It also provides you download of the whole book. May be this will help. if you are just starting servlets may be it's a good idea to read the material along with the servlet API. it's a slower process of learning, but is way more helpful in getting the basics clear.

There are two ways :

1. using .htaccess : Options -Indexes

2. create blank index.html

You can try using res.redirect to the https file download url, and then it will be downloading the file.

Like: res.redirect('https//static.file.com/file.txt');

U can do it easier than this answers :

Uri Selected_Image_Uri = data.getData();
ImageView imageView = (ImageView) findViewById(R.id.loadedimg);
imageView.setImageURI(Selected_Image_Uri);

Yes, but be careful when using between for dates.

BETWEEN '20090101' AND '20090131'

is really interpreted as 12am, or

BETWEEN '20090101 00:00:00' AND '20090131 00:00:00'

so will miss anything that occurred during the day of Jan 31st. In this case, you will have to use:

myDate >= '20090101 00:00:00' AND myDate < '20090201 00:00:00'  --CORRECT!

or

BETWEEN '20090101 00:00:00' AND '20090131 23:59:59' --WRONG! (see update!)

UPDATE: It is entirely possible to have records created within that last second of the day, with a datetime as late as 20090101 23:59:59.997!!

For this reason, the BETWEEN (firstday) AND (lastday 23:59:59) approach is not recommended.

Use the myDate >= (firstday) AND myDate < (Lastday+1) approach instead.

Good article on this issue here.

To add the background for all cells (using Maciej's answer):

for (int section = 0; section < [self.tableView numberOfSections]; section++) {
        for (int row = 0; row < [self.tableView numberOfRowsInSection:section]; row++) {
            NSIndexPath* cellPath = [NSIndexPath indexPathForRow:row inSection:section];
            UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:cellPath];

            //stuff to do with each cell
            UIView *bgColorView = [[UIView alloc] init];
            bgColorView.backgroundColor = [UIColor redColor];
            [cell setSelectedBackgroundView:bgColorView];
        }
    } 

Since Python evaluates also the data type NoneType as False during the check, a more precise answer is:

var = False
if var is False:
    print('learnt stuff')

This prevents potentially unwanted behaviour such as:

var = []  # or None
if not var:
    print('learnt stuff') # is printed what may or may not be wanted

But if you want to check all cases where var will be evaluated to False, then doing it by using logical not keyword is the right thing to do.

Firebase Remote Config is better.

• Quickly and easily update our applications without the need to publish a new build to the app

Implementing Remote Config on Android

Adding the Remote Config dependancy

compile 'com.google.firebase:firebase-config:9.6.0'

Once done, we can then access the FirebaseRemoteConfig instance throughout our application where required:

FirebaseRemoteConfig firebaseRemoteConfig = FirebaseRemoteConfig.getInstance();

Retrieving Remote Config values

boolean someBoolean = firebaseRemoteConfig.getBoolean("some_boolean");
byte[] someArray = firebaseRemoteConfig.getByteArray("some_array");
double someDouble = firebaseRemoteConfig.getDouble("some_double");
long someLong = firebaseRemoteConfig.getLong("some_long");
String appVersion = firebaseRemoteConfig.getString("appVersion");

Fetch Server-Side values

firebaseRemoteConfig.fetch(cacheExpiration)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if (task.isSuccessful()) {
                        mFirebaseRemoteConfig.activateFetched();
                        // We got our config, let's do something with it!
                        if(appVersion < CurrentVersion){
                           //show update dialog
                        }
                    } else {
                        // Looks like there was a problem getting the config...
                    }
                }
            });

Now once uploaded the new version to playstore, we have to update the version number inside firebase. Now if it is new version the update dialog will display

UPDATE for VS 2017:

Looks people in Nuget team finally started to use Nuget themselves which helped them to find and fix several important things. So now (if I'm not mistaken, as still didn't migrated to VS 2017) the below is not necessary any more. You should be able to set the "repositoryPath" to a local folder and it will work. Even you can leave it at all as by default restore location moved out of solution folders to machine level. Again - I still didn't test it by myself

VS 2015 and earlier

Just a tip to other answers (specifically this):

Location of the NuGet Package folder can be changed via configuration, but VisualStudio still reference assemblies in this folder relatively:

<HintPath>..\..\..\..\..\..\SomeAssembly\lib\net45\SomeAssembly.dll</HintPath>

To workaround this (until a better solution) I used subst command to create a virtual drive which points to a new location of the Packages folder:

subst N: C:\Development\NuGet\Packages

Now when adding a new NuGet package, the project reference use its absolute location:

<HintPath>N:\SomeAssembly\lib\net45\SomeAssembly.dll</HintPath>

Note:

1. Such a virtual drive will be deleted after restart, so make sure you handle it
2. Don't forget to replace existing references in project files.

I don't think the accepted solution handles the case where the error text is reported on stderr. From my testing the exception's output attribute did not contain the results from stderr and the docs warn against using stderr=PIPE in check_output(). Instead, I would suggest one small improvement to J.F Sebastian's solution by adding stderr support. We are, after all, trying to handle errors and stderr is where they are often reported.

from subprocess import Popen, PIPE

p = Popen(['bitcoin', 'sendtoaddress', ..], stdout=PIPE, stderr=PIPE)
output, error = p.communicate()
if p.returncode != 0: 
   print("bitcoin failed %d %s %s" % (p.returncode, output, error))

If it's not important to use a RelativeLayout, you could use a LinearLayout, and do this:

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

Doing this allows you to avoid the addRule method you've tried. You can simply use addView() to add new TextViews.

Complete code:

String[] textArray = {"One", "Two", "Three", "Four"};
LinearLayout linearLayout = new LinearLayout(this);
setContentView(linearLayout);
linearLayout.setOrientation(LinearLayout.VERTICAL);        
for( int i = 0; i < textArray.length; i++ )
{
    TextView textView = new TextView(this);
    textView.setText(textArray[i]);
    linearLayout.addView(textView);
}

If you are working with heavy queries, you better move the request for the latest row in the where clause. It is a lot faster and looks cleaner.

SELECT c.*,
FROM client AS c
LEFT JOIN client_calling_history AS cch ON cch.client_id = c.client_id
WHERE
   cch.cchid = (
      SELECT MAX(cchid)
      FROM client_calling_history
      WHERE client_id = c.client_id AND cal_event_id = c.cal_event_id
   )

If these are elements naturally in the tab order like buttons and anchors, removing them from the tab order with tabindex="-1" is kind of an accessibility smell. If they're providing duplicate functionality removing them from the tab order is ok, and consider adding aria-hidden="true" to these elements so assistive technologies will ignore them.

I had major trouble getting this to work in RCx releases of angular2. The Location package has moved, and running location.go() inside constructor() wont work. It needs to be ngOnInit() or later in the lifecycle. Here is some example code:

import {OnInit} from '@angular/core';
import {Location} from '@angular/common';

@Component({
  selector: 'example-component',
  templateUrl: 'xxx.html'
})
export class ExampleComponent implements OnInit
{
  constructor( private location: Location )
  {}

  ngOnInit()
  {    
    this.location.go( '/example;example_param=917' );
  }
}

Here are the angular resources on the matter: https://angular.io/docs/ts/latest/api/common/index/Location-class.html https://angular.io/docs/ts/latest/api/common/index/LocationStrategy-class.html

If you're using .NET 3.5, you can use HashSet<T>. It's true that .NET doesn't cater for sets as well as Java does though.

The Wintellect PowerCollections may help too.

From my experience, it is ideal to set variables as private and to provide accessors and modifiers to each variable.

This way, you can create read only variables, or write only variables depending on your requirements.

Below implementation shows a write only variable.

private String foo;
public void setFoo(String foo) { this.foo = foo; }
private String getFoo() { return foo; }

Below shows a read only variable.

private String foo;
private void setFoo(String foo) { this.foo = foo; }
public String getFoo() { return foo; }

It's worked for me:

1. Download SDK from https://cloud.google.com/sdk/docs/install
2. Extract the archive to my home directory (my home is "nintran")
3. Run "./google-cloud-sdk/bin/gcloud init"

I feel your pain and I wasted all night/morning trying to figure this out. With sheer brute force I figured out a solution. Call it a workaround - but it's simple.

Add the CssClass property to your Menu Control's declaration like so:

<asp:Menu ID="NavigationMenu" DataSourceID="NavigationSiteMapDataSource"
        CssClass="SomeMenuClass"
        StaticMenuStyle-CssClass="StaticMenuStyle"
        StaticMenuItemStyle-CssClass="StaticMenuItemStyle"
        Orientation="Horizontal" 
        MaximumDynamicDisplayLevels="0" 
        runat="server">
</asp:Menu>

Just rip out the StaticSelectedStyle-CssClass and StaticHoverStyle-CssClass attributes as they simply don't do jack.

Now create the "SomeMenuClass", doesn't matter what you put in it. It should look something like this:

.SomeMenuClass
{
    color:Green;
}

Next add the following two CSS Classes:

For "Hover" Styling add:

.SomeMenuClass a.static.highlighted
{
    color:Red !important;
}

For "Selected" Styling add:

.SomeMenuClass a.static.selected
{
    color:Blue !important;
}

There, that's it. You're done. Hope this saves some of you the frustration I went through. BTW: You mentioned:

I seem to be the first one to ever report on what seems to be a bug.

You also seemed to think it was a new .NET 4.0 bug. I found this: http://www.velocityreviews.com/forums/t649530-problem-with-staticselectedstyle-and-statichoverstyle.html posted back in 2008 regarding Asp.Net 2.0 . How are we the only 3 people on the planet complaining about this?

How I found the workaround (study the HTML output):

Here is the HTML output when I set StaticHoverStyle-BackColor="Red":

#NavigationMenu a.static.highlighted
{
    background-color:Red;
}

This is the HTML output when setting StaticSelectedStyle-BackColor="Blue":

#NavigationMenu a.static.selected
{
    background-color:Blue;
    text-decoration:none;
}

Therefore, the logical way to override this markup was to create classes for SomeMenuClass a.static.highlighted and SomeMenuClass a.static.selected

Special Notes:

You MUST also use "!important" on ALL the settings in these classes because the HTML output uses "#NavigationMenu", and that means any styles Asp.Net decides to throw in there for you will have inheritance priority over any other styles for the Menu Control with the ID "NavigationMenu". One thing I struggled with was padding, till I figured out Asp.Net was using "#NavigationMenu" to set the left and right padding to 15em. I tacked on "!important" to my SomeMenuClass styles and it worked.

IN KOTLIN :

Suppose that you have a String like this :

private val phoneNumber="9121111111"

At first you should get the first one :

val firstChar=phoneNumber.slice(0..0)

At second you can check the first char that return a Boolean :

firstChar.isInt() // or isFloat()

For logging to Logback with help from Apache HttpClient:

You need Apache HttpClient in classpath:

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.5.10</version>
</dependency>

Configure your RestTemplate to use HttpClient:

restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

To log requests and responses, add to Logback configuration file:

<logger name="org.apache.http.wire" level="DEBUG"/>

Or to log even more:

<logger name="org.apache.http" level="DEBUG"/>

I solved the problem with this code:

using System.IO;

var path = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location.Substring(0, Assembly.GetEntryAssembly().Location.IndexOf("bin\\")))

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

I suggest, you use the MaskedTextBox: http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.aspx

In general Android OS leverages a “theme” to allow app developers to globally apply a universal set of UI element styling parameters to Android applications as a whole, or, alternatively, to a single Activity subclass.

So there are three mainstream Android OS “system themes,” which you can specify in your Android Manifest XML file when you are developing apps for Version 3.0 and later versions

I am referring the (APPCOMPAT)support library here:-- So the three themes are 1. AppCompat Light Theme (Theme.AppCompat.Light)

2. AppCompat Dark Theme(Theme.AppCompat),

3. And a hybrid between these two ,AppCompat Light Theme with the Darker ActionBar.( Theme.AppCompat.Light.DarkActionBar)

AndroidManifest.xml and see the tag, the android theme is mentioned as:-- android:theme="@style/AppTheme"

Open the Styles.xml and we have base application theme declared there:--

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  </style>

We need to override these parent theme elements to style the action bar.

ActionBar with different color background:--

To do this we need to create a new style MyActionBar(you can give any name) with a parent reference to @style/Widget.AppCompat.Light.ActionBar.Solid.Inverse that holds the style characteristics for the Android ActionBar UI element. So definition would be

<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="background">@color/red</item>
</style>

And this definition we need to reference in our AppTheme, pointing to overridden ActionBar styling as--

@style/MyActionBar

Change the title bar text color (e.g black to white):--

Now to change the title text color, we need to override the parent reference parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">

So the style definition would be

<style name="MyActionBarTitle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textColor">@color/white</item>
</style>

We’ll reference this style definition inside the MyActionBar style definition, since the TitleTextStyle modification is a child element of an ActionBar parent OS UI element. So the final definition of MyActionBar style element will be

<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="background">@color/red</item>
    <item name="titleTextStyle">@style/MyActionBarTitle</item>
</style>

SO this is the final Styles.xml

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- This is the styling for action bar -->
        <item name="actionBarStyle">@style/MyActionBar</item>
    </style>

    <style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
        <item name="background">@color/red</item>
        <item name="titleTextStyle">@style/MyActionBarTitle</item>
    </style>

    <style name="MyActionBarTitle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
        <item name="android:textColor">@color/white</item>
    </style>
</resources>

With the suggestions @jhadesdev and the explanations from others, I've found the issue here.

After adding the code to see what was visible to the various class loaders I found this:

All versions of log4j Logger: 
  zip:<snip>war/WEB-INF/lib/log4j-1.2.17.jar!/org/apache/log4j/Logger.class

All versions of log4j visible from the classloader of the OAuthAuthorizer class: 
  zip:<snip>war/WEB-INF/lib/log4j-1.2.17.jar!/org/apache/log4j/Logger.class

All versions of XMLConfigurator: 
  jar:<snip>com.bea.core.bea.opensaml2_1.0.0.0_6-1-0-0.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/ipp-java-aggcat-v1-devkit-1.0.2.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/xmltooling-1.3.1.jar!/org/opensaml/xml/XMLConfigurator.class

All versions of XMLConfigurator visible from the classloader of the OAuthAuthorizer class: 
  jar:<snip>com.bea.core.bea.opensaml2_1.0.0.0_6-1-0-0.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/ipp-java-aggcat-v1-devkit-1.0.2.jar!/org/opensaml/xml/XMLConfigurator.class
  zip:<snip>war/WEB-INF/lib/xmltooling-1.3.1.jar!/org/opensaml/xml/XMLConfigurator.class

I noticed that another version of XMLConfigurator was possibly getting picked up. I decompiled that class and found this at line 60 (where the error was in the original stack trace) private static final Logger log = Logger.getLogger(XMLConfigurator.class); and that class was importing from org.apache.log4j.Logger!

So it was this class that was being loaded and used. My fix was to rename the jar file that contained this file as I can't find where I explicitly or indirectly load it. Which may pose a problem when I actually deploy.

Thanks for all help and the much needed lesson on class loading.

Reader's Digest: (Spark 2.x)

For Example, if you have 3 directories holding csv files:

dir1, dir2, dir3

You then define paths as a string of comma delimited list of paths as follows:

paths = "dir1/,dir2/,dir3/*"

Then use the following function and pass it this paths variable

def get_df_from_csv_paths(paths):

        df = spark.read.format("csv").option("header", "false").\
            schema(custom_schema).\
            option('delimiter', '\t').\
            option('mode', 'DROPMALFORMED').\
            load(paths.split(','))
        return df

By then running:

df = get_df_from_csv_paths(paths)

You will obtain in df a single spark dataframe containing the data from all the csvs found in these 3 directories.

===========================================================================

Full Version:

In case you want to ingest multiple CSVs from multiple directories you simply need to pass a list and use wildcards.

For Example:

if your data_path looks like this:

's3://bucket_name/subbucket_name/2016-09-*/184/*,
s3://bucket_name/subbucket_name/2016-10-*/184/*,
s3://bucket_name/subbucket_name/2016-11-*/184/*,
s3://bucket_name/subbucket_name/2016-12-*/184/*, ... '

you can use the above function to ingest all the csvs in all these directories and subdirectories at once:

This would ingest all directories in s3 bucket_name/subbucket_name/ according to the wildcard patterns specified. e.g. the first pattern would look in

bucket_name/subbucket_name/

for all directories with names starting with

2016-09-

and for each of those take only the directory named

184

and within that subdirectory look for all csv files.

And this would be executed for each of the patterns in the comma delimited list.

This works way better than union..

This could cause for any new terminal, the agent id is different. You need to add the Private key for the agent

$ ssh-add <path to your private key>

you can use android:inputType="textMultiLine"

  <TextView android:id="@+id/address1"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:gravity="left"
    android:maxLines="4" 
    android:inputType="textMultiLine"
    android:text="Johar Mor, Gulistan-e-Johar, Karachi" />

in my case (laravel 5+) i had to wrap my password in single quotation marks and clear config cache:

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=user_name
DB_PASSWORD='password'

and then run:

php artisan config:clear

After taking a closer look at the Mongoose API with the information provided by Rodolphe, I figured out this solution:

MyModel.find(query, fields, { skip: 10, limit: 5 }, function(err, results) { ... });

Look at the jQuery unload function. It handles all the things.

https://api.jquery.com/unload/

The unload event is sent to the window element when the user navigates away from the page. This could mean one of many things. The user could have clicked on a link to leave the page, or typed in a new URL in the address bar. The forward and back buttons will trigger the event. Closing the browser window will cause the event to be triggered. Even a page reload will first create an unload event.

$(window).unload(
    function(event) {
        alert("navigating");
    }
);

In Visual Studio 2017 you need to make sure you're not in release configuration mode.

1. Open the build menu ddl
2. Click configuration manager
3. Change from 'release' to 'debug'

No, they don't exist.

I know that the C# team was considering them at one point (or at least Eric Lippert was) - along with extension constructors and operators (those may take a while to get your head around, but are cool...) However, I haven't seen any evidence that they'll be part of C# 4.

EDIT: They didn't appear in C# 5, and as of July 2014 it doesn't look like it's going to be in C# 6 either.

Eric Lippert, the Principal Developer on the C# compiler team at Microsoft thru November 2012, blogged about this in October of 2009:

• Why No Extension Properties? – Fabulous Adventures In Coding

I came to this question needing to prevent text wrapping at the hyphen.

This is how I did it:

<td><nobr>Table Text</nobr></td>

Reference:

How to prevent line break at hyphens on all browsers

I think the reason that this is happening could be because TextBox1 is scoping to the VBA module and its associated sheet, while Range is scoping to the "Active Sheet".

EDIT

It looks like you may be able to use the GetObject function to pull the textbox from the workbook.

Use .height() like this:

var result = $("#myDiv").height();

There's also .innerHeight() and .outerHeight() depending on exactly what you want.

You can test it here, play with the padding/margins/content to see how it changes around.

Of course that works; when @item1 = N'', it IS NOT NULL.

You can define @item1 as NULL by default at the top of your stored procedure, and then not pass in a parameter.

In this model, you have publishers who will do some logic and publish an "event."
Publishers will then send out their event only to subscribers who have subscribed to receive the specific event.

In C#, any object can publish a set of events to which other applications can subscribe.
When the publishing class raises an event, all the subscribed applications are notified.
The following figure shows this mechanism.

Simplest Example possible on Events and Delegates in C#:

code is self explanatory, Also I've added the comments to clear out the code.

  using System;

public class Publisher //main publisher class which will invoke methods of all subscriber classes
{
    public delegate void TickHandler(Publisher m, EventArgs e); //declaring a delegate
    public TickHandler Tick;     //creating an object of delegate
    public EventArgs e = null;   //set 2nd paramter empty
    public void Start()     //starting point of thread
    {
        while (true)
        {
            System.Threading.Thread.Sleep(300);
            if (Tick != null)   //check if delegate object points to any listener classes method
            {
                Tick(this, e);  //if it points i.e. not null then invoke that method!
            }
        }
    }
}

public class Subscriber1                //1st subscriber class
{
    public void Subscribe(Publisher m)  //get the object of pubisher class
    {
        m.Tick += HeardIt;              //attach listener class method to publisher class delegate object
    }
    private void HeardIt(Publisher m, EventArgs e)   //subscriber class method
    {
        System.Console.WriteLine("Heard It by Listener");
    }

}
public class Subscriber2                   //2nd subscriber class
{
    public void Subscribe2(Publisher m)    //get the object of pubisher class
    {
        m.Tick += HeardIt;               //attach listener class method to publisher class delegate object
    }
    private void HeardIt(Publisher m, EventArgs e)   //subscriber class method
    {
        System.Console.WriteLine("Heard It by Listener2");
    }

}

class Test
{
    static void Main()
    {
        Publisher m = new Publisher();      //create an object of publisher class which will later be passed on subscriber classes
        Subscriber1 l = new Subscriber1();  //create object of 1st subscriber class
        Subscriber2 l2 = new Subscriber2(); //create object of 2nd subscriber class
        l.Subscribe(m);     //we pass object of publisher class to access delegate of publisher class
        l2.Subscribe2(m);   //we pass object of publisher class to access delegate of publisher class

        m.Start();          //starting point of publisher class
    }
}

Output:

Heard It by Listener

Heard It by Listener2

Heard It by Listener

Heard It by Listener2

Heard It by Listener . . . (infinite times)

The answers above are so wrong! DO NOT add custom headers. Judging from your sample xml, it is a standard WS-Security header. WCF definitely supports it out of the box. When you add a service reference you should have basicHttpBinding binding created for you in the config file. You will have to modify it to include security element with mode TransportWithMessageCredential and message element with clientCredentialType = UserName:

<basicHttpBinding>
  <binding name="usernameHttps">
    <security mode="TransportWithMessageCredential">
      <message clientCredentialType="UserName"/>
    </security>
  </binding>
</basicHttpBinding>

The config above is telling WCF to expect userid/password in the SOAP header over HTTPS. Then you can set id/password in your code before making a call:

var service = new MyServiceClient();
service.ClientCredentials.UserName.UserName = "username";
service.ClientCredentials.UserName.Password = "password";

Unless this particular service provider deviated from the standard, it should work.

If you have access to the code that creates the canvas - simply call the function right there after the canvas is created.

If you have no access to that code (eg. If it is a 3rd party code such as google maps) then what you could do is test for the existence in an interval:

var checkExist = setInterval(function() {
   if ($('#the-canvas').length) {
      console.log("Exists!");
      clearInterval(checkExist);
   }
}, 100); // check every 100ms

But note - many times 3rd party code has an option to activate your code (by callback or event triggering) when it finishes to load. That may be where you can put your function. The interval solution is really a bad solution and should be used only if nothing else works.

You can use this script to export or import any database from terminal given at this link: https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh

echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo

mysqldump_location=/opt/lampp/bin/mysqldump
mysql_location=/opt/lampp/bin/mysql

if [ "$action" == "export" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
        echo
    else
        echo -e "Using default location of mysqldump\n"
    fi
    read -p 'Give the name of database in which you would like to export: ' db_name
    read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
    $mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysql that you want to use: ' mysql_location
        echo
    else
        echo -e "Using default location of mysql\n"
    fi
    read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
    read -p 'Give the name of database in which to import this file: ' db_name
    $mysql_location -u $u_name -p $db_name < $sql_file
else
    echo "please select a valid command"
fi

choose a low resolution emulator (eg: Nexus S) if you don't have a good graphic card (like me)

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

The only solution that works for me on Linux, Mac and Windows:

public static String getJarContainingFolder(Class aclass) throws Exception {
  CodeSource codeSource = aclass.getProtectionDomain().getCodeSource();

  File jarFile;

  if (codeSource.getLocation() != null) {
    jarFile = new File(codeSource.getLocation().toURI());
  }
  else {
    String path = aclass.getResource(aclass.getSimpleName() + ".class").getPath();
    String jarFilePath = path.substring(path.indexOf(":") + 1, path.indexOf("!"));
    jarFilePath = URLDecoder.decode(jarFilePath, "UTF-8");
    jarFile = new File(jarFilePath);
  }
  return jarFile.getParentFile().getAbsolutePath();
}

tl;dr

Use either of the Map implementations bundled with Java 6 and later that implement NavigableMap (the successor to SortedMap):

• Use TreeMap if running single-threaded, or if the map is to be read-only across threads after first being populated.
• Use ConcurrentSkipListMap if manipulating the map across threads.

NavigableMap

FYI, the SortedMap interface was succeeded by the NavigableMap interface.

You would only need to use SortedMap if using 3rd-party implementations that have not yet declared their support of NavigableMap. Of the maps bundled with Java, both of the implementations that implement SortedMap also implement NavigableMap.

Interface versus concrete class

s SortedMap the best answer? TreeMap?

As others mentioned, SortedMap is an interface while TreeMap is one of multiple implementations of that interface (and of the more recent NavigableMap.

Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.

NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ; 
currentAssignments.put( bob , setUpNewVendorsProject ) ; 

This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:

NavigableMap< Employee , Project > currentAssignments = new ConcurrentSkipListMap<>() ;

…and the rest of your code using that map continues to work.

Choosing implementation

There are ten implementations of Map bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.

Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap remembers original insertion order.

You can use recursion here to do this. For example:

jQuery(document).ready(checkContainer);

function checkContainer () {
  if($('#divIDer').is(':visible'))){ //if the container is visible on the page
    createGrid();  //Adds a grid to the html
  } else {
    setTimeout(checkContainer, 50); //wait 50 ms, then try again
  }
}

Basically, this function will check to make sure that the element exists and is visible. If it is, it will run your createGrid() function. If not, it will wait 50ms and try again.

Note:: Ideally, you would just use the callback function of your AJAX call to know when the container was appended, but this is a brute force, standalone approach. :)

Match duplicate comma-delimited items:

(?<=,|^)([^,]*)(,\1)+(?=,|$)

Reference.

This regex can be used to split the values of a comma delimitted list. List elements may be quoted, unquoted or empty. Commas inside a pair of quotation marks are not matched.

,(?!(?<=(?:^|,)\s*"(?:[^"]|""|\\")*,)(?:[^"]|""|\\")*"\s*(?:,|$))

Reference.

I tried what Samuel Slade has suggested. Didn't work for me. The PropertyInfo list was coming as empty. So, I tried the following and it worked for me.

    Type type = typeof(Record);
    FieldInfo[] properties = type.GetFields();
    foreach (FieldInfo property in properties) {
       Debug.LogError(property.Name);
    }

Create a sub-class User with an id field and screen_name field, like this:

public class User
{
    public string id { get; set; }
    public string screen_name { get; set; }
}

public class Response {

    public string id { get; set; }
    public string text { get; set; }
    public string url { get; set; }
    public string width { get; set; }
    public string height { get; set; }
    public string size { get; set; }
    public string type { get; set; }
    public string timestamp { get; set; }
    public User user { get; set; }
}

Works with over 100 lines, if you specify the size of the file in the headers simple call the get() method in your own class

function setHeader($filename, $filesize)
{
    // disable caching
    $now = gmdate("D, d M Y H:i:s");
    header("Expires: Tue, 01 Jan 2001 00:00:01 GMT");
    header("Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate");
    header("Last-Modified: {$now} GMT");

    // force download  
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header('Content-Type: text/x-csv');

    // disposition / encoding on response body
    if (isset($filename) && strlen($filename) > 0)
        header("Content-Disposition: attachment;filename={$filename}");
    if (isset($filesize))
        header("Content-Length: ".$filesize);
    header("Content-Transfer-Encoding: binary");
    header("Connection: close");
}

function getSql()
{
    // return you own sql
    $sql = "SELECT id, date, params, value FROM sometable ORDER BY date;";
    return $sql;
}

function getExportData()
{
    $values = array();

    $sql = $this->getSql();
    if (strlen($sql) > 0)
    {
        $result = dbquery($sql); // opens the database and executes the sql ... make your own ;-) 
        $fromDb = mysql_fetch_assoc($result);
        if ($fromDb !== false)
        {
            while ($fromDb)
            {
                $values[] = $fromDb;
                $fromDb = mysql_fetch_assoc($result);
            }
        }
    }
    return $values;
}

function get()
{
    $values = $this->getExportData(); // values as array 
    $csv = tmpfile();

    $bFirstRowHeader = true;
    foreach ($values as $row) 
    {
        if ($bFirstRowHeader)
        {
            fputcsv($csv, array_keys($row));
            $bFirstRowHeader = false;
        }

        fputcsv($csv, array_values($row));
    }

    rewind($csv);

    $filename = "export_".date("Y-m-d").".csv";

    $fstat = fstat($csv);
    $this->setHeader($filename, $fstat['size']);

    fpassthru($csv);
    fclose($csv);
}

flexbox can help you. info here

<div class="d-flex flex-row justify-content-center align-items-center" style="height: 100px;">
    <div class="p-2">
     1
    </div>
    <div class="p-2">
     2
    </div>
</div>

CSS can do that with background-size: cover;

But to be more detailed and support more browsers...

Use aspect ratio like this:

 aspectRatio      = $bg.width() / $bg.height();

FIDDLE

You can use Decode as well:

SELECT DISTINCT a.item, decode(b.salesman,'VIKKIE','ICKY',Else),NVL(a.manufacturer,'Not Set')Manufacturer
FROM inv_items a, arv_sales b
WHERE a.co = b.co
      AND A.ITEM_KEY = b.item_key
      AND a.co = '100'
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
                         and to_date('011713','mmddrr')
GROUP BY a.item, b.salesman, a.manufacturer
ORDER BY a.item

Infact, 2 dimensional array is the list of list of X, where X is one of your data structures from typical ones to user-defined ones. As the following snapshot code, I added row by row into an array triangle. To create each row, I used the method add to add elements manually or the method asList to create a list from a band of data.

package algorithms;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class RunDemo {

/**
 * @param args
 */
public static void main(String[] args) {
    // Get n
    List<List<Integer>> triangle = new ArrayList<List<Integer>>();

    List<Integer> row1 = new ArrayList<Integer>(1);
    row1.add(2);
    triangle.add(row1);

    List<Integer> row2 = new ArrayList<Integer>(2);
    row2.add(3);row2.add(4);
    triangle.add(row2);

    triangle.add(Arrays.asList(6,5,7));
    triangle.add(Arrays.asList(4,1,8,3));

    System.out.println("Size = "+ triangle.size());
    for (int i=0; i<triangle.size();i++)
        System.out.println(triangle.get(i));

}
}

Running the sample, it generates the output:

Size = 4
[2]
[3, 4]
[6, 5, 7]
[4, 1, 8, 3]

Building on Iain's example, I had a similar need to compose these emails with separate plaintext, HTML and multiple attachments, but using PHP. Since we are using Amazon SES to send emails with attachments, the API currently requires you to build the email from scratch using the sendRawEmail(...) function.

After much investigation (and greater than normal frustration), the problem was solved and the PHP source code posted so that it may help others experiencing a similar problem. Hope this help someone out - the troop of monkeys I forced to work on this problem are now exhausted.

I am not clearly about it but typically one server has one database (with many users), if you create many databases mean that you create many instances, listeners, ... as well. So you can check your LISTENER to identify it.

In my testing I created 2 databases (dbtest and dbtest_1) so when I check my LISTENER status it appeared like this:

lsnrctl status

....

STATUS of the LISTENER

.....

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=10.10.20.20)(PORT=1521)))

Services Summary...

Service "dbtest" has 1 instance(s).

Instance "dbtest", status READY, has 1 handler(s) for this service...

Service "dbtest1XDB" has 1 instance(s).

Instance "dbtest1", status READY, has 1 handler(s) for this service...

Service "dbtest_1" has 1 instance(s).

Instance "dbtest1", status READY, has 1 handler(s) for this service... The command completed successfully

jQuery.i18n is a lightweight jQuery plugin for enabling internationalization in your web pages. It allows you to package custom resource strings in ‘.properties’ files, just like in Java Resource Bundles. It loads and parses resource bundles (.properties) based on provided language or language reported by browser.

to know more about this take a look at the How to internationalize your pages using JQuery?

Because nobody knows a fast algorithm to factorize an integer into its prime factors. Yet, it is very easy to check if a set of prime factors multiply to a certain integer.

The ?type=daily argument (ending up in the $_GET array) is only valid for web-accessed pages.

You'll need to call it like php myfile.php daily and retrieve that argument from the $argv array (which would be $argv[1], since $argv[0] would be myfile.php).

If the page is used as a webpage as well, there are two options you could consider. Either accessing it with a shell script and Wget, and call that from cron:

#!/bin/sh
wget http://location.to/myfile.php?type=daily

Or check in the PHP file whether it's called from the command line or not:

if (defined('STDIN')) {
  $type = $argv[1];
} else {
  $type = $_GET['type'];
}

(Note: You'll probably need/want to check if $argv actually contains enough variables and such)

Using awk, and based in some of the options below, using a for loop makes a bit more flexible; sometimes I may want to delete the first 9 columns ( if I do an "ls -lrt" for example), so I change the 2 for a 9 and that's it:

awk '{ for(i=0;i++<2;){$i=""}; print $0 }' your_file.txt

None of these answers worked satisfactorily for me. They either didn't fix the table heading row in place or they required fixed column widths to work, and even then tended to have the heading row and body rows misaligned in various browsers.

I recommend biting the bullet and using a proper grid control like jsGrid or my personal favorite, SlickGrid. It obviously introduces a dependency but if you want your tables to behave like real grids with cross-browser support, this will save you pulling your hair out. It also gives you the option of sorting and resizing columns plus tons of other features if you want them.

My Visual Studio 2015 RTM was also very slow using ReSharper 9.1.2, but it has worked fine since I upgraded to 9.1.3 (see ReSharper 9.1.3 to the Rescue). Perhaps a cue.

One more cue. A ReSharper 9.2 version was made available to:

refines integration with Visual Studio 2015 RTM, addressing issues discovered in versions 9.1.2 and 9.1.3

you should calculate the complexity of algorithms used by the methods OrderBy and Sort. QuickSort has a complexity of n (log n) as i remember, where n is the length of the array.

i've searched for orderby's too, but i could not find any information even in msdn library. if you have not any same values and sorting related to only one property, i prefer to use Sort() method; if not than use OrderBy.

Calling conventions defines how parameters are passed in the registers when calling or being called by other program. And the best source of these convention is in the form of ABI standards defined for each these hardware. For ease of compilation, the same ABI is also used by userspace and kernel program. Linux/Freebsd follow the same ABI for x86-64 and another set for 32-bit. But x86-64 ABI for Windows is different from Linux/FreeBSD. And generally ABI does not differentiate system call vs normal "functions calls". Ie, here is a particular example of x86_64 calling conventions and it is the same for both Linux userspace and kernel: http://eli.thegreenplace.net/2011/09/06/stack-frame-layout-on-x86-64/ (note the sequence a,b,c,d,e,f of parameters):

Performance is one of the reasons for these ABI (eg, passing parameters via registers instead of saving into memory stacks)

For ARM there is various ABI:

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.swdev.abi/index.html

https://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iPhoneOSABIReference/iPhoneOSABIReference.pdf

ARM64 convention:

http://infocenter.arm.com/help/topic/com.arm.doc.ihi0055b/IHI0055B_aapcs64.pdf

For Linux on PowerPC:

http://refspecs.freestandards.org/elf/elfspec_ppc.pdf

http://www.0x04.net/doc/elf/psABI-ppc64.pdf

And for embedded there is the PPC EABI:

This document is good overview of all the different conventions:

-p|--parent will be used if you are trying to create a directory with top-down approach. That will create the parent directory then child and so on iff none exists.

-p, --parents no error if existing, make parent directories as needed

About rlidwka it means giving full or administrative access. Found it here https://itservices.stanford.edu/service/afs/intro/permissions/unix.

I wrote a class to normalize the data in my dictionary. The 'element' in the NormalizeData class below, needs to be of dict type. And you need to replace in the __iterate() with either your custom class object or any other object type that you would like to normalize.

class NormalizeData:

    def __init__(self, element):
        self.element = element

    def execute(self):
        if isinstance(self.element, dict):
            self.__iterate()
        else:
            return

    def __iterate(self):
        for key in self.element:
            if isinstance(self.element[key], <ClassName>):
                self.element[key] = str(self.element[key])

            node = NormalizeData(self.element[key])
            node.execute()

You can try java.time api;

        Instant date = Instant.ofEpochMilli(1549362600000l);
        LocalDateTime utc = LocalDateTime.ofInstant(date, ZoneOffset.UTC);

If min value in array, you can try like:

>>> mydict = {"a": -1.5, "b": -1000.44, "c": -3}
>>> min(mydict.values())
-1000.44

The best way is to check the type, because undefined/null/false are a tricky thing in JS. So:

if(typeof obj !== "undefined") {
    // obj is a valid variable, do something here.
}

Note that typeof always returns a string, and doesn't generate an error if the variable doesn't exist at all.

Enjoy this :) Without cast each value individually.

SELECT ...,
  IsCoursedBased = CAST(
      CASE WHEN fc.CourseId is not null THEN 1 ELSE 0 END
    AS BIT
  )
FROM fc

Date d1 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date1));
Date d2 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date2));

long diff = d2.getTime() - d1.getTime();

System.out.println("Difference between  " + d1 + " and "+ d2+" is "
        + (diff / (1000 * 60 * 60 * 24)) + " days.");

A good way of going about this is not to use nargin, but to check whether the variables have been set using exist('opt', 'var').

Example:

function [a] = train(x, y, opt)
    if (~exist('opt', 'var'))
        opt = true;
    end
end

See this answer for pros of doing it this way: How to check whether an argument is supplied in function call?

I would strongly recommend business rules engines like Drools as open source or Commercial Rules Engine such as LiveRules.

• When you have a lot of business policies which are volatile in nature, it is very hard to maintain that part of the core technology code.
• The rules engine provides a great flexibility of the framework and easy to change and deploy.
• Rules engines are not to be used everywhere but need to used when you have lot of policies where changes are inevitable on a regular basis.

There isn't a simple solution. The way I've done it in the past is to start another process to run either the ps command on Unix-like systems, or the tasklist command on Windows, and then parse the output of that command for the PID I want. In reality, I ended up putting that code into a separate shell script for each platform which just returned the PID, so that I could keep the Java piece as platform independent as possible. This doesn't work well for short-lived tasks, but that wasn't an issue for me.

The Update table1 set (a,b,c) = (select x,y,x) syntax is an example of the use of row-value constructors, Oracle supports this, MSSQL does not. (Connect item)

You could use find to solve your problem

https://lodash.com/docs/#find

const data = [{"a": 1}, {"b": 2}]
const item = {"b": 2}


find(data, item)
// > true

On Windows the easiest way is to use the program portecle.

1. Download and install portecle.
2. First make 100% sure you know which JRE or JDK is being used to run your program. On a 64 bit Windows 7 there could be quite a few JREs. Process Explorer can help you with this or you can use: System.out.println(System.getProperty("java.home"));
3. Copy the file JAVA_HOME\lib\security\cacerts to another folder.
4. In Portecle click File > Open Keystore File
5. Select the cacerts file
6. Enter this password: changeit
7. Click Tools > Import Trusted Certificate
8. Browse for the file mycertificate.pem
9. Click Import
10. Click OK for the warning about the trust path.
11. Click OK when it displays the details about the certificate.
12. Click Yes to accept the certificate as trusted.
13. When it asks for an alias click OK and click OK again when it says it has imported the certificate.
14. Click save. Don’t forget this or the change is discarded.
15. Copy the file cacerts back where you found it.

On Linux:

You can download the SSL certificate from a web server that is already using it like this:

$ echo -n | openssl s_client -connect www.example.com:443 | \
   sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/examplecert.crt

Optionally verify the certificate information:

$ openssl x509 -in /tmp/examplecert.crt -text

Import the certificate into the Java cacerts keystore:

$ keytool -import -trustcacerts -keystore /opt/java/jre/lib/security/cacerts \
   -storepass changeit -noprompt -alias mycert -file /tmp/examplecert.crt

There is no need to use any plugin, you can do it like this:

var divPosition = $('#divId').offset();

then use this to scroll document to specific DOM:

$('html, body').animate({scrollTop: divPosition.top}, "slow");

I would recommend loading the file as Resource and converting the input stream into string. This would give you the flexibility to load the file anywhere relative to the classpath

You will have to create an auto-increment field with the sequence object (this object generates a number sequence).

Use the following CREATE SEQUENCE syntax:

  CREATE SEQUENCE seq_person
  MINVALUE 1
  START WITH 1
  INCREMENT BY 1
  CACHE 10

The code above creates a sequence object called seq_person, that starts with 1 and will increment by 1. It will also cache up to 10 values for performance. The cache option specifies how many sequence values will be stored in memory for faster access.

To insert a new record into the "Persons" table, we will have to use the nextval function (this function retrieves the next value from seq_person sequence):

  INSERT INTO Persons (P_Id,FirstName,LastName)
  VALUES (seq_person.nextval,'Lars','Monsen')

The SQL statement above would insert a new record into the "Persons" table. The "P_Id" column would be assigned the next number from the seq_person sequence. The "FirstName" column would be set to "Lars" and the "LastName" column would be set to "Monsen".

An old question, but I'll answer anyway. The answer to the actual question asked is that the bare return is redundant and should be left out.

Furthermore, the suggested value is false for the following reason:

if (ret<0) return;

Redefining a C reserved word as a macro is a bad idea on the face of it, but this particular suggestion is simply unsupportable, both as an argument and as code.

Because you are asking the compiler to initialize a static variable with code that is inherently dynamic.

The modern event handling method:

element.addEventListener('click', startDragDrop, false);
element.addEventListener('click', spyOnUser, false);

The first argument is the event, the second is the function and the third specifies whether to allow event bubbling.

W3C’s DOM Level 2 Event specification pays careful attention to the problems of the traditional model. It offers a simple way to register as many event handlers as you like for the same event on one element.

The key to the W3C event registration model is the method addEventListener(). You give it three arguments: the event type, the function to be executed and a boolean (true or false) that I’ll explain later on. To register our well known doSomething() function to the onclick of an element you do:

Using jQuery

if you're using jQuery, there is a nice API for event handling:

$('#myElement').bind('click', function() { doStuff(); });
$('#myElement').bind('click', function() { doMoreStuff(); });
$('#myElement').bind('click', doEvenMoreStuff);

Another correct way to get selected value would be using this selector:

$("option[value="0"]:selected")

Best for you!

You need the st_size property of the object returned by os.stat. You can get it by either using pathlib (Python 3.4+):

>>> from pathlib import Path
>>> Path('somefile.txt').stat()
os.stat_result(st_mode=33188, st_ino=6419862, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=1564, st_atime=1584299303, st_mtime=1584299400, st_ctime=1584299400)
>>> Path('somefile.txt').stat().st_size
1564

or using os.stat:

>>> import os
>>> os.stat('somefile.txt')
os.stat_result(st_mode=33188, st_ino=6419862, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=1564, st_atime=1584299303, st_mtime=1584299400, st_ctime=1584299400)
>>> os.stat('somefile.txt').st_size
1564

Output is in bytes.

Here you have an example of a Dockerfile that runs nginx. As mentionned by Charles, it uses the daemon off configuration:

https://github.com/darron/docker-nginx-php5/blob/master/Dockerfile#L17

android:backgroundTintMode

Blending mode used to apply the background tint.

android:backgroundTint

Tint to apply to the background. Must be a color value, in the form of #rgb, #argb, #rrggbb, or #aarrggbb.

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

Embarrassing to say it, but when I had this problem, it was simply a mistake that I was closing the connection before I read all the data. In cases with small strings being returned, it worked, but that was probably due to the whole response was buffered, before I closed it.

In cases of longer amounts of text being returned, the exception was thrown, since more then a buffer was coming back.

You might check for this oversight. Remember opening a URL is like a file, be sure to close it (release the connection) once it has been fully read.

A simple SQL example would be like this:

ALTER TABLE `<table_name>` ADD `<column_name>` INT(11) NULL DEFAULT NULL ;

Make sure you use back ticks `` in table name and column name

Since you don't know how many comma-delimited entries you can find, you may need to create a function with 'charindex' and 'substring' SQL Server functions. Values, as returned by the function could be used in a 'in' expression.

You function can be recursively invoked or you can create loop, searching for entries until no more entries are present in the string. Every call to the function uses the previous found index as the starting point of the next call. The first call starts at 0.

I found the above answer giving an error with Oracle SQL, you also must use square brackets, below;

SQL> SELECT Q'[Paddy O'Reilly]' FROM DUAL;

Result: Paddy O'Reilly

You still can run it from File explorer on Windows 10 with the proper path. You just need to go to C:\Users\user\AppData\Local\Android\Sdk\tools\lib\monitor-x86_64 and double click the file monitor.

If you want to use in the cmd just the 'monitor' command you have to add this folder (in my case with android studio 3.4.1 and win10) to your Environment variables. So, press the start button and then type Edit the system environment variabes click it and System properties window should open. Then go to

Environment variables => System variables => path

press the Edit button for path and add the new value

C:\Users\user\AppData\Local\Android\Sdk\tools\lib\monitor-x86_64

click 'Ok', 'Ok' and 'Ok' and restart the cmd window if you had it opened and type 'monitor' and it should open the monitor as well.

Hope it helps!

PD: This answer was based on this answer https://stackoverflow.com/a/55077068/5360905 from Tiago Martins Peres

The answer is, "No."

What C programmers do is store the size of the array somewhere. It can be part of a structure, or the programmer can cheat a bit and malloc() more memory than requested in order to store a length value before the start of the array.

Although this post is very old. In case if somebody is looking for this..

Guava facilitates partitioning the List into sublists of a specified size

List<Integer> intList = Lists.newArrayList(1, 2, 3, 4, 5, 6, 7, 8);
    List<List<Integer>> subSets = Lists.partition(intList, 3);

You don't need to add the concat package, you can do this via cssmin like this:

cssmin : {
      options: {
            keepSpecialComments: 0
      },
      minify : {
            expand : true,
            cwd : '/library/css',
            src : ['*.css', '!*.min.css'],
            dest : '/library/css',
            ext : '.min.css'
      },
      combine : {
        files: {
            '/library/css/app.combined.min.css': ['/library/css/main.min.css', '/library/css/font-awesome.min.css']
        }
      }
    }

And for js, use uglify like this:

uglify: {
      my_target: {
        files: {
            '/library/js/app.combined.min.js' : ['/app.js', '/controllers/*.js']
        }
      }
    }

If you keep on allocating & keeping references to object, you will fill up any amount of memory you have.

One option is to do a transparent file close & open when they switch tabs (you only keep a pointer to the file, and when the user switches tab, you close & clean all the objects... it'll make the file change slower... but...), and maybe keep only 3 or 4 files on memory.

Other thing you should do is, when the user opens a file, load it, and intercept any OutOfMemoryError, then (as it is not possible to open the file) close that file, clean its objects and warn the user that he should close unused files.

Your idea of dynamically extending virtual memory doesn't solve the issue, for the machine is limited on resources, so you should be carefull & handle memory issues (or at least, be carefull with them).

A couple of hints i've seen with memory leaks is:

--> Keep on mind that if you put something into a collection and afterwards forget about it, you still have a strong reference to it, so nullify the collection, clean it or do something with it... if not you will find a memory leak difficult to find.

--> Maybe, using collections with weak references (weakhashmap...) can help with memory issues, but you must be carefull with it, for you might find that the object you look for has been collected.

--> Another idea i've found is to develope a persistent collection that stored on database objects least used and transparently loaded. This would probably be the best approach...

jQuery is a JavaScript library, that can be used for communicating (selecting html elements, attaching event listeners, animations etc.) with the DOM, creating and consuming AJAX requests, as well as other things in a more easier way rather than using plain JavaScript. jQuery is written in JavaScript. It should be mentioned that browsers parse only HTML, CSS and JavaScript files. Hence, all JavaScript libraries/frameworks (jQuery, Knockout, Angular) are written in JavaScript or in languages like TypeScript that transconpiles to JavaScript (e.g. Angular 2). They provide you the opportunity to write less lines of codes or to create interfaces following patterns like MVC (e.g. Angular), MVVM (e.g. Knockout) as well as other patterns, but under the hood, they are all result in a JavaScript file.

An example in order to understand why using jQuery you write less do more is the following.

Let we have the following input element

<input id="button1" type="button" value="clickMe"/> 

Also, let that we want when someone clicks on the button to be notified through an alert box showing to the user a 'Hello' message.

If we had to do this using plain JavaScript, we would have written the following:

document.getElementById("button1")
        .addEventListener('click', function(){ 
            alert("Hello");
        });

On the other hand, if we were using jQuery, we would had achieved the same result by just writing this:

$('#button1').click(function(){ 
    alert("Hello"); 
});

Using jQuery makes things more clear than using plain JavaScript for the same purpose. (write less do more is jQuery's moto)

Furthermore, jQuery handles pretty well the theme of browser compatibility, you can use their API pretty easily without wondering too much as if you should do in case of using plain JavaScript.

Below I have added snippets for the code above:

document.getElementById("button1")_x000D_
        .addEventListener('click', function(){ _x000D_
            alert("Hello");_x000D_
        });

<input id="button1" type="button" value="clickMe"/>

$('#button1').click(function(){ alert("Hello"); });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input id="button1" type="button" value="clickMe"/>

ALTER TABLE [TableName] ADD CONSTRAINT  [constraintName] UNIQUE ([columns])

This query uses the Group By and and Having clauses to allow you to select (locate and list out) for each duplicate record. The As clause is a convenience to refer to Quantity in the select and Order By clauses, but is not really part of getting you the duplicate rows.

Select
    Title,
    Count( Title ) As [Quantity]
   From
    Training
   Group By
    Title
   Having 
    Count( Title ) > 1
   Order By
    Quantity desc

I ran into the same problem and found that the documentation has example for this type of scenario (where we write STDERR TO STDOUT and always exit successfully with return code 0) without causing/catching an exception.

output = subprocess.check_output("ping -c 2 -W 2 1.1.1.1; exit 0", stderr=subprocess.STDOUT, shell=True)

Now, you can use standard string function find to check the output string output.

As other have said, compiled and interpreted are specific to an implementation of a programming language; they are not inherent in the language. For example, there are C interpreters.

However, we can (and in practice we do) classify programming languages based on its most common (sometimes canonical) implementation. For example, we say C is compiled.

First, we must define without ambiguity interpreters and compilers:

An interpreter for language X is a program (or a machine, or just some kind of mechanism in general) that executes any program p written in language X such that it performs the effects and evaluates the results as prescribed by the specification of X.

A compiler from X to Y is a program (or a machine, or just some kind of mechanism in general) that translates any program p from some language X into a semantically equivalent program p' in some language Y in such a way that interpreting p' with an interpreter for Y will yield the same results and have the same effects as interpreting p with an interpreter for X.

Notice that from a programmer point of view, CPUs are machine interpreters for their respective native machine language.

Now, we can do a tentative classification of programming languages into 3 categories depending on its most common implementation:

• Hard Compiled languages: When the programs are compiled entirely to machine language. The only interpreter used is a CPU. Example: Usually, to run a program in C, the source code is compiled to machine language, which is then executed by a CPU.
• Interpreted languages: When there is no compilation of any part of the original program to machine language. In other words, no new machine code is generated; only existing machine code is executed. An interpreter other than the CPU must also be used (usually a program).Example: In the canonical implementation of Python, the source code is compiled first to Python bytecode and then that bytecode is executed by CPython, an interpreter program for Python bytecode.
• Soft Compiled languages: When an interpreter other than the CPU is used but also parts of the original program may be compiled to machine language. This is the case of Java, where the source code is compiled to bytecode first and then, the bytecode may be interpreted by the Java Interpreter and/or further compiled by the JIT compiler.

Sometimes, soft and hard compiled languages are refered to simply compiled, thus C#, Java, C, C++ are said to be compiled.

Within this categorization, JavaScript used to be an interpreted language, but that was many years ago. Nowadays, it is JIT-compiled to native machine language in most major JavaScript implementations so I would say that it falls into soft compiled languages.

Bootstrap 2 , 3 Check is any modal open in page :

if($('.modal.show').length)

I used simply string baseDir = Environment.CurrentDirectory; and its work for me.

Good Luck

Edit:

I used to delete this type of mistake but i prefer to edit it because i think the minus point on this answer help people to know about wrong way. :) I understood the above solution is not useful and i changed it to string appBaseDir = System.AppDomain.CurrentDomain.BaseDirectory; Other ways to get it are:

1. string baseDir =   
    System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
 2. String exePath = System.Environment.GetCommandLineArgs()[0];
 3. string appBaseDir =    System.IO.Path.GetDirectoryName
    (System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);

Good Luck

I deleted all .suo and .user files and restarted VS 2008. But it didn't worked for me. The following steps worked for me.

Open project file (.csproj) in notepad.
Removed all configurations from <Configurations></COnfigurations> tag.
Then add one by one configuration and reload project in VS.
Build the project or view project properties.

os.homedir() was added by this PR and is part of the public 4.0.0 release of nodejs.

Example usage:

const os = require('os');

console.log(os.homedir());

This worked for me using sed [Edit: comment below points out sed doesn't support \s]

[^ ]

while

[^\s] 

didn't

# Delete everything except space and 'g'
echo "ghai ghai" | sed "s/[^\sg]//g"
gg

echo "ghai ghai" | sed "s/[^ g]//g"
g g

Have a look at either Left or Substring if you need to chop it up even more.

Google and the MySQL docs are a good place to start - you'll usually not get such a warm response if you've not even tried to help yourself before asking a question.

Run R in emacs with ESS (Emacs Speaks Statistics) r-mode. I have one window open with my script and R code. Another has R running. Code is sent from the syntax window and evaluated. Commands, output, errors, and warnings all appear in the running R window session. At the end of some work period, I save all the output to a file. My own naming system is *.R for scripts and *.Rout for save output files. Here's a screenshot with an example.

Below approach of frame handling : When no id or name is given incase of nested frame

WebElement element =driver.findElement(By.xpath(".//*[@id='block-block19']//iframe"));
driver.switchTo().frame(element);
driver.findElement(By.xpath(".//[@id='carousel']/li/div/div[3]/a")).click();

Import the JavaScript file jquery.validate.min.js.

You can use this method:

$.validator.addMethod("pwcheck", function (value) {
    return /[\@\#\$\%\^\&\*\(\)\_\+\!]/.test(value) && /[a-z]/.test(value) && /[0-9]/.test(value) && /[A-Z]/.test(value)
});

1. At least one upper case English letter
2. At least one lower case English letter
3. At least one digit
4. At least one special character

I think the easiest way is to simply use AttributeRouting.

It's obvious within your controller, why would you want this in your Global WebApiConfig file?

Example:

    [Route("api/YOURCONTROLLER/{paramOne}/{paramTwo}")]
    public string Get(int paramOne, int paramTwo)
    {
        return "The [Route] with multiple params worked";
    }

The {} names need to match your parameters.

Simple as that, now you have a separate GET that handles multiple params in this instance.

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

Yes what everybody says above.

For your immediate situation, instead of onChange, you can use onInput, new in html5. The input event is the same, but it'll fire upon every keystroke, regardless of the focus. Also works on selects and all the rest just like onChange.

According to bitbucket knowledgebase it may also be caused by the owner of the repository being over the plan limit.

If you look further down the page it seems to also be possible to trig this error by using a too old git version (1.7 is needed at the moment).

I tried all of these solutions before I realized that I had enabled opcache in PHP on my live environment. Wordpress was not reading a cached version of wp-config.

This is a very interesting question and I hope my thought below could contribute an way of solution to it. This method do give a flat list without indexing, but it does have list and unlist to avoid the nesting structures. I'm not sure about the speed since I don't know how to benchmark it.

a_list<-list()
for(i in 1:3){
  a_list<-list(unlist(list(unlist(a_list,recursive = FALSE),list(rnorm(2))),recursive = FALSE))
}
a_list

From a performance point of view, it doesn't matter in Python, and I'd assume the same for every modern language out there.

It really comes down to style and readability. Your second option (if-else block) is more readable than the first, and a lot more readable than the one-liner ternary operation.

The error is due to corrupt or missing SSL chain certificate files in the PKI directory. You’ll need to make sure the files ca-bundle, following steps: In your console/terminal:

mkdir /usr/src/ca-certificates && cd /usr/src/ca-certificates

Enter this site: https://rpmfind.net/linux/rpm2html/search.php?query=ca-certificates , get your ca-certificate, for yout SO, for example: ftp://rpmfind.net/linux/fedora/linux/updates/24/x86_64/c/ca-certificates-2016.2.8-1.0.fc24.noarch.rpm << CentOS.

If installed Django using python setup.py install

python -c "import sys; sys.path = sys.path[1:]; import django; print(django.__path__)"

find the directory you need to remove, delete it

See Ruby on Rails: Delete multiple hash keys

hash.delete_if{ |k,| keys_to_delete.include? k }

Not sure if I get you right, but the simplest way would be something like:

<c:if test="${languageBean.locale == 'en'">
  <f:selectItems value="#{customerBean.selectableCommands_limited_en}" />
</c:if>

Just a quick copy and paste from an app of mine...

Use a criteria of "<>". It will count anything which isn't an empty cell, including #NAME? or #DIV/0!. As to why it works, damned if I know, but Excel seems to understand it.

Note: works nicely in Google Spreadsheet too

fastest one:

$("div#selected ul li").length

You may also try to use the serialize() function. Sometimes it is very useful for debugging purposes.

Go to >system preferences >mysql >initialize database

-Change password -Click use legacy password -Click start sql server

it should work now

All the answers above refer to either setting the memory to a certain extent in TensorFlow 1.X versions or to allow memory growth in TensorFlow 2.X.

The method tf.config.experimental.set_memory_growth indeed works for allowing dynamic growth during the allocation/preprocessing. Nevertheless one may like to allocate from the start a specific GPU memory.

The logic behind allocating a specific GPU memory would also be to prevent OOM memory during training sessions. For example, if one trains while opening video-memory consuming Chrome tabs/any other video consumption process, the tf.config.experimental.set_memory_growth(gpu, True) could result in OOM errors thrown, hence the necessity of allocating from the start more memory in certain cases.

The recommended and correct way in which to allot memory per GPU in TensorFlow 2.X is done in the following manner:

gpus = tf.config.experimental.list_physical_devices('GPU')
if gpus:
  # Restrict TensorFlow to only allocate 1GB of memory on the first GPU
  try:
    tf.config.experimental.set_virtual_device_configuration(
        gpus[0],
        [tf.config.experimental.VirtualDeviceConfiguration(memory_limit=1024)]

Although it is safe to declare a static ObjectMapper in terms of thread safety, you should be aware that constructing static Object variables in Java is considered bad practice. For more details, see Why are static variables considered evil? (and if you'd like, my answer)

In short, statics should be avoided because the make it difficult to write concise unit tests. For example, with a static final ObjectMapper, you can't swap out the JSON serialization for dummy code or a no-op.

In addition, a static final prevents you from ever reconfiguring ObjectMapper at runtime. You might not envision a reason for that now, but if you lock yourself into a static final pattern, nothing short of tearing down the classloader will let you re-initialize it.

In the case of ObjectMapper its fine, but in general it is bad practice and there is no advantage over using a singleton pattern or inversion-of-control to manage your long-lived objects.

You need to modify the method GetData() and add your "experimental" code there, and return t1.

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

IMHO, Edizkan Adil Ata's idea is actually the most proper way. It extracts the URLs of anchor tags and puts them in a different tag. And if you don't want to let the anchors being seen by the page visitor then just .hide() them all with JQuery or display: none; in CSS.

Also you can perform prefetching, like this:

<link rel="prefetch" href="imagefolder/clouds.jpg" />

That way you don't have to hide it and still can extract the path to the image.

I realize this question is a bit old but here's a really simple solution that was missing. You don't need to create a custom ListView or even a custom layout.

Just create an anonymous subclass of ArrayAdapter and override getView(). Let super.getView() handle all the heavy lifting. Since simple_list_item_1 is just a text view you can customize it (e.g. set textColor) and then return it.

Here's an example from one of my apps. I'm displaying a list of recent locations and I want all occurrences of "Current Location" to be blue and the rest white.

ListView listView = (ListView) this.findViewById(R.id.listView);
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, MobileMuni.getBookmarkStore().getRecentLocations()) {
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        TextView textView = (TextView) super.getView(position, convertView, parent);

        String currentLocation = RouteFinderBookmarksActivity.this.getResources().getString(R.string.Current_Location);
        int textColor = textView.getText().toString().equals(currentLocation) ? R.color.holo_blue : R.color.text_color_btn_holo_dark;
        textView.setTextColor(RouteFinderBookmarksActivity.this.getResources().getColor(textColor));

        return textView;
    }
});

Yes, this is frequently called a multimap.

See: http://google-collections.googlecode.com/svn/trunk/javadoc/index.html?com/google/common/collect/Multimap.html

I have simply pasted the following to the top of my bash scripts:

#!/usr/bin/env bash -e

declare script=$(basename "$0")
declare dirname=$(dirname "$0")
declare scriptDir
if [[ $(uname) == 'Linux' ]];then
    # use readlink -f
    scriptDir=$(readlink -f "$dirname")
else
    # can't use readlink -f, do a pwd -P in the script directory and then switch back
    if [[ "$dirname" = '.' ]];then
        # don't change directory, we are already inside
        scriptDir=$(pwd -P)
    else
        # switch to the directory and then switch back
        pwd=$(pwd)
        cd "$dirname"
        scriptDir=$(pwd -P)
        cd "$pwd"
    fi
fi

And removed all instances of readlink -f. $scriptDir and $script then will be available for the rest of the script.

While this does not follow all symlinks, it works on all systems and appears to be good enough for most use cases, it switches the directory into the containing folder, and then it does a pwd -P to get the real path of that directory, and then finally switch back to the original.

There's a bit of confusion in your question:

• a Date datatype doesn't save the time zone component. This piece of information is truncated and lost forever when you insert a TIMESTAMP WITH TIME ZONE into a Date.
• When you want to display a date, either on screen or to send it to another system via a character API (XML, file...), you use the TO_CHAR function. In Oracle, a Date has no format: it is a point in time.
• Reciprocally, you would use TO_TIMESTAMP_TZ to convert a VARCHAR2 to a TIMESTAMP, but this won't convert a Date to a TIMESTAMP.
• You use FROM_TZ to add the time zone information to a TIMESTAMP (or a Date).
• In Oracle, CST is a time zone but CDT is not. CDT is a daylight saving information.
• To complicate things further, CST/CDT (-05:00) and CST/CST (-06:00) will have different values obviously, but the time zone CST will inherit the daylight saving information depending upon the date by default.

So your conversion may not be as simple as it looks.

Assuming that you want to convert a Date d that you know is valid at time zone CST/CST to the equivalent at time zone CST/CDT, you would use:

SQL> SELECT from_tz(d, '-06:00') initial_ts,
  2         from_tz(d, '-06:00') at time zone ('-05:00') converted_ts
  3    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  4                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  5            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
09/10/12 01:10:21,000000 -06:00 09/10/12 02:10:21,000000 -05:00

My default timestamp format has been used here. I can specify a format explicitely:

SQL> SELECT to_char(from_tz(d, '-06:00'),'yyyy-mm-dd hh24:mi:ss TZR') initial_ts,
  2         to_char(from_tz(d, '-06:00') at time zone ('-05:00'),
  3                 'yyyy-mm-dd hh24:mi:ss TZR') converted_ts
  4    FROM (SELECT cast(to_date('2012-10-09 01:10:21',
  5                              'yyyy-mm-dd hh24:mi:ss') as timestamp) d
  6            FROM dual);

INITIAL_TS                      CONVERTED_TS
------------------------------- -------------------------------
2012-10-09 01:10:21 -06:00      2012-10-09 02:10:21 -05:00

One explanation might be floating point rounding issues. For example, if you could call

range(0, 0.4, 0.1)

you might expect an output of

[0, 0.1, 0.2, 0.3]

but you in fact get something like

[0, 0.1, 0.2000000001, 0.3000000001]

due to rounding issues. And since range is often used to generate indices of some sort, it's integers only.

Still, if you want a range generator for floats, you can just roll your own.

def xfrange(start, stop, step):
    i = 0
    while start + i * step < stop:
        yield start + i * step
        i += 1

I'm using

$("input:radio[name='html_radio']").is(":checked")

And will return FALSE if all the items in the radiogroup are unchecked and TRUE if an item is checked.

Use toCharArray() method. It splits the string into an array of characters:

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#toCharArray%28%29

String str = "aabbab";
char[] chs = str.toCharArray();

Here I've collected the "good ones" from this page and put them into a simple test pattern for you to evaluate on your own.

For newbies, the console.log is a built in function (available in all modern browsers) that lets you output results to the JavaScript console (dig around, you'll find it) rather than having to output to your HTML page.

var isNumeric = function(val){
    // --------------------------
    // Recommended
    // --------------------------

    // jQuery - works rather well
    // See CMS's unit test also: http://dl.getdropbox.com/u/35146/js/tests/isNumber.html
    return !isNaN(parseFloat(val)) && isFinite(val);

    // Aquatic - good and fast, fails the "0x89f" test, but that test is questionable.
    //return parseFloat(val)==val;

    // --------------------------
    // Other quirky options
    // --------------------------
    // Fails on "", null, newline, tab negative.
    //return !isNaN(val);

    // user532188 - fails on "0x89f"
    //var n2 = val;
    //val = parseFloat(val);
    //return (val!='NaN' && n2==val);

    // Rafael - fails on negative + decimal numbers, may be good for isInt()?
    // return ( val % 1 == 0 ) ? true : false;

    // pottedmeat - good, but fails on stringy numbers, which may be a good thing for some folks?
    //return /^-?(0|[1-9]\d*|(?=\.))(\.\d+)?$/.test(val);

    // Haren - passes all
    // borrowed from http://www.codetoad.com/javascript/isnumeric.asp
    //var RE = /^-{0,1}\d*\.{0,1}\d+$/;
    //return RE.test(val);

    // YUI - good for strict adherance to number type. Doesn't let stringy numbers through.
    //return typeof val === 'number' && isFinite(val);

    // user189277 - fails on "" and "\n"
    //return ( val >=0 || val < 0);
}

var tests = [0, 1, "0", 0x0, 0x000, "0000", "0x89f", 8e5, 0x23, -0, 0.0, "1.0", 1.0, -1.5, 0.42, '075', "01", '-01', "0.", ".0", "a", "a2", true, false, "#000", '1.2.3', '#abcdef', '', "", "\n", "\t", '-', null, undefined];

for (var i=0; i<tests.length; i++){
    console.log( "test " + i + ":    " + tests[i] + "    \t   " + isNumeric(tests[i]) );
}

If you are using Maven, add the below config in your pom.xml:

<build>
    <testResources>
                <testResource>
                    <directory>src/main/webapp</directory>
                </testResource>
    </testResources>
</build>

With this config, you will be able to access xml files in WEB-INF folder. From Maven POM Reference: The testResources element block contains testResource elements. Their definitions are similar to resource elements, but are naturally used during test phases.

import re
re.sub('<.*?>', '', string)
"i think mabe 124 + but I don't have a big experience it just how I see it in my eyes fun stuff"

The re.sub function takes a regular expresion and replace all the matches in the string with the second parameter. In this case, we are searching for all tags ('<.*?>') and replacing them with nothing ('').

The ? is used in re for non-greedy searches.

More about the re module.

function TellFirstCharacterType(inputString){
    var firstCharacter = inputString[0];
    if(isNaN(firstCharacter)){
        if(firstCharacter == firstCharacter.toUpperCase()){
            return "It's a uppercase character";
        }
        else{
            return "It's a lowercase character";
        }
    }
    else{
        return "It's a Number";
    }
}

I've found this to work the best across all browsers and devices (PC, tables & mobile).

<script type="text/javascript">
                      function iframeLoaded() {
                          var iFrameID = document.getElementById('idIframe');
                          if(iFrameID) {
                                // here you can make the height, I delete it first, then I make it again
                                iFrameID.height = "";
                                iFrameID.height = iFrameID.contentWindow.document.body.scrollHeight + "px";
                          }   
                      }
                    </script> 


<iframe id="idIframe" onload="iframeLoaded()" frameborder="0" src="yourpage.php" height="100%" width="100%" scrolling="no"></iframe>

I just benchmarked the top answer posted above in my own code (a recursive tree walk) and the simple concat operator is actually faster than the BufferString.

func (r *record) String() string {
    buffer := bytes.NewBufferString("");
    fmt.Fprint(buffer,"(",r.name,"[")
    for i := 0; i < len(r.subs); i++ {
        fmt.Fprint(buffer,"\t",r.subs[i])
    }
    fmt.Fprint(buffer,"]",r.size,")\n")
    return buffer.String()
}

This took 0.81 seconds, whereas the following code:

func (r *record) String() string {
    s := "(\"" + r.name + "\" ["
    for i := 0; i < len(r.subs); i++ {
        s += r.subs[i].String()
    }
    s += "] " + strconv.FormatInt(r.size,10) + ")\n"
    return s
} 

only took 0.61 seconds. This is probably due to the overhead of creating the new BufferString.

Update: I also benchmarked the join function and it ran in 0.54 seconds.

func (r *record) String() string {
    var parts []string
    parts = append(parts, "(\"", r.name, "\" [" )
    for i := 0; i < len(r.subs); i++ {
        parts = append(parts, r.subs[i].String())
    }
    parts = append(parts, strconv.FormatInt(r.size,10), ")\n")
    return strings.Join(parts,"")
}

import queue is lowercase q in Python 3.

Change Q to q and it will be fine.

(See code in https://stackoverflow.com/a/29688081/632951 for smart switching.)

None of the solutions worked for me as of today. My situation was that I got my Android studio updated. The most popular thing to replace the tools folder with the latest one wouldn't work for me. Infact is not required in some cases.

npm update -g cordova did the trick for me.

Then I removed the platform and added it again.

ionic platform remove android

ionic platform add android

This works for me in Ionic. I am surecordova platform remove/add android will do the same stuff. Not tested though.

Working again !

Path Customization (tested in laravel 7) When a user is successfully authenticated, they will be redirected to the /home URI. You can customize the post-authentication redirect path using the HOME constant defined in your RouteServiceProvider:

public const HOME = '/home';

background-position-x: center;
background-position-y: center;

Extending Django User Model (UserProfile) like a Pro

I've found this very useful: link

An extract:

    department = models.CharField(max_length=100)

>>> u = User.objects.get(username='fsmith')
>>> freds_department = u.employee.department

To pass arguments to the jar:

java -jar myjar.jar one two

You can access them in the main() method of "Main-Class" (mentioned in the manifest.mf file of a JAR).

String one = args[0];

None of the answers here quite hit the nail on the head.

How to store a datetime in MySQL with timezone info

Use two columns: DATETIME, and a VARCHAR to hold the time zone information, which may be in several forms:

A timezone or location such as America/New_York is the highest data fidelity.

A timezone abbreviation such as PST is the next highest fidelity.

A time offset such as -2:00 is the smallest amount of data in this regard.

Some key points:

• Avoid TIMESTAMP because it's limited to the year 2038, and MySQL relates it to the server timezone, which is probably undesired.
• A time offset should not be stored naively in an INT field, because there are half-hour and quarter-hour offsets.

If it's important for your use case to have MySQL compare or sort these dates chronologically, DATETIME has a problem:

'2009-11-10 11:00:00 -0500' is before '2009-11-10 10:00:00 -0700' in terms of "instant in time", but they would sort the other way when inserted into a DATETIME.

You can do your own conversion to UTC. In the above example, you would then have
'2009-11-10 16:00:00' and '2009-11-10 17:00:00' respectively, which would sort correctly. When retrieving the data, you would then use the timezone info to revert it to its original form.

One recommendation which I quite like is to have three columns:

• local_time DATETIME
• utc_time DATETIME
• time_zone VARCHAR(X) where X is appropriate for what kind of data you're storing there. (I would choose 64 characters for timezone/location.)

An advantage to the 3-column approach is that it's explicit: with a single DATETIME column, you can't tell at a glance if it's been converted to UTC before insertion.

Regarding the descent of accuracy through timezone/abbreviation/offset:

• If you have the user's timezone/location such as America/Juneau, you can know accurately what the wall clock time is for them at any point in the past or future (barring changes to the way Daylight Savings is handled in that location). The start/end points of DST, and whether it's used at all, are dependent upon location, so this is the only reliable way.
• If you have a timezone abbreviation such as MST, (Mountain Standard Time) or a plain offset such as -0700, you will be unable to predict a wall clock time in the past or future. For example, in the United States, Colorado and Arizona both use MST, but Arizona doesn't observe DST. So if the user uploads his cat photo at 14:00 -0700 during the winter months, was he in Arizona or California? If you added six months exactly to that date, would it be 14:00 or 13:00 for the user?

These things are important to consider when your application has time, dates, or scheduling as core function.

The delimiter can be a regular expression.

awk -F'[/=]' '{print $3 "\t" $5 "\t" $8}' file

Produces:

tc0001   tomcat7.1    demo.example.com  
tc0001   tomcat7.2    quest.example.com  
tc0001   tomcat7.5    www.example.com

The question is dead but still knowing one more way doesn't hurt:

my_list = [ (old1, new1), (old2, new2), (old3, new3), ... (oldN, newN)]

for first,*args in my_list:
    if first == Value:
        PAIR_FOUND = True
        MATCHING_VALUE = args
        break

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, "");

Result:

"Hello, this is Mike"

You can also set LD_RUN_PATH to /usr/local/lib in your user environment when you compile pycurl in the first place. This will embed /usr/local/lib in the RPATH attribute of the C extension module .so so that it automatically knows where to find the library at run time without having to have LD_LIBRARY_PATH set at run time.

Ronal, to answer your question in the comment in my answer above:

function wasClicked(str)
{
  return str+' def';
}

At least on 10.10.5, system_profiler SPUSBDataType output is NOT dynamically updated when a new USB device gets plugged in, while ioreg -p IOUSB -l -w 0 does.

You can use the report process status ps command:

ps ax | grep '[m]ysqld'

You have 2 options here to do that either to discard all your outgoing commits OR to undo specific commit ..

1- Discard all your outgoing commits:

To discard all your outgoing commits For example if you have local branch named master from remote branch, You can:

1- Rename your local branch from master to anything so you can remove it. 2- Remove the renamed branch. 3- create new branch from the master

So now you have a new branch without your commits ..

2- Undo specific commit: To undo specific commit you have to revert the unneeded by:

1- Double click on the unneeded commit. Double click on the unneeded commit 2- Click on revert Click on revert

But FYI the reverted commit will appear in the history of your commits with the revert commit ..

import array
integerValue = array.array("I", 'y\xcc\xa6\xbb')[0]

Warning: the above is strongly platform-specific. Both the "I" specifier and the endianness of the string->int conversion are dependent on your particular Python implementation. But if you want to convert many integers/strings at once, then the array module does it quickly.

• You can set environment variables as mentioned in the other answers (like here)

  or

• you can open Start > CMD as administrator and write

  C:\xampp\php phpfile.php

e.preventDefault(); with jquery ui

For me this problem occured with the click method override on a jquery ui button, causing a page reload on click by default.

Alternatively, if nothing works (as was my case) you can revert to searching and downloading a whl file here:

https://pypi.org/project/fileDownloader.py/

Before installing it via pip using the downloaded file which won't require any certificate anymore:

python3.7 -m pip install Myfile.whl

print [s for s in list if sub in s]

If you want them separated by newlines:

print "\n".join(s for s in list if sub in s)

Full example, with case insensitivity:

mylist = ['abc123', 'def456', 'ghi789', 'ABC987', 'aBc654']
sub = 'abc'

print "\n".join(s for s in mylist if sub.lower() in s.lower())

As for me, most elegant way is yield break

Try the following code:

public static byte[] decode(String hex){

        String[] list=hex.split("(?<=\\G.{2})");
        ByteBuffer buffer= ByteBuffer.allocate(list.length);
        System.out.println(list.length);
        for(String str: list)
            buffer.put(Byte.parseByte(str,16));

        return buffer.array();

}

To convert to String just create a new String with the byte[] returned by the decode method.

Dim connString as String ="server=localhost;userid=root;password=123456;database=uni_park_db"
Dim conn as MySqlConnection(connString)

Dim cmd = new MySqlCommand(sql, conn)

    cmd.Paramaters.AddwithValue("@car_id", txtCar.Text)
    cmd.Paramaters.AddwithValue("@member_id", txtMember.Text)
    cmd.Paramaters.AddwithValue("@model", txtModel.Text)

    cmd.Paramaters.AddwithValue("@plate_number", txtPlateNo.Text)
    cmd.Paramaters.AddwithValue("@code", txtCode.Text)

    Try
        conn.Open()
        If cmd.ExecuteNonQuery() > 0 Then
            ireturn = True
        End If  
        conn.Close()


    Catch ex as Exception
        ireturn = False
        conn.Close()
    End Try

Return ireturn

End Sub

All the previous answers do not define how to add the plugin manager in your Notepad++ installation.

This is for the folks who do not see the the plugin manager in the plugin tab

Download the plugin manager from this link - this is for the 64-bit plugin manager. Once you download the plugin manager, paste in the plugin folder. This is was my location of plugin folder: C:\Program Files\Notepad++\plugins

After pasting the .dll file restart Notepad++. Now you can install any plugin. To install a plugin, click on the plugin tab, then go to plugin manager and select the plugin whatever you want.

This should do the work:

.category_table tr:first-child td {
    vertical-align: top;
}

WINDOWS Apache 2.4.x + PHP 7.0.x SOLUTION HERE:

Solution: Put libeay32.dll, libssh2.dll, ssleay32.dll files under dir specified in httpd.conf's ServerRoot directive. These dlls can be found compiled under php root folder.

Reasons:

Problem is php_curl.dll requires to access following libraries while loading: libeay32.dll, libssh2.dll, ssleay32.dll and it does not make sense if you put them in ./php/ext dir or if you put php extensions in php root dir.

Of course you can put them in c:\Windows or in some global folder defined in PATH but if you dont want to do this and you want that your apache+php installation was portable:

The path specified in ServerRoot in httpd.conf is treated as home path for php. The behaviour is similar to situation where you include ./path/to/some.php file in ./index.php and home path for some.php file is still ./ the dir where index.php resides.

In shorts just put those three dlls right in dir you specified in httpd.conf ServerRoot directive and php_curl.dll will not fail to load again.

What about using mysql -v to put mysql client in verbose mode ?

You don't need to wrap it in a list with [..], just provide the subselection of the columns index:

df.drop(df.columns[[1, 69]], axis=1, inplace=True)

as the index object is already regarded as list-like.

As it mentioned above assigning more than 50 % RAM memory to your emmulator.

For me fixed this way too.

My machine have 8GB and I assigned 4GB for per device. Resetting it solve my problem.
