You can use the dataSourceClassName approach, here is an example with MySQL. (Tested with spring boot 1.3 and 1.4)

First you need to exclude tomcat-jdbc from the classpath as it will be picked in favor of hikaricp.

pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.apache.tomcat</groupId>
                <artifactId>tomcat-jdbc</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

application.properties

spring.datasource.dataSourceClassName=com.mysql.jdbc.jdbc2.optional.MysqlDataSource
spring.datasource.dataSourceProperties.serverName=localhost
spring.datasource.dataSourceProperties.portNumber=3311
spring.datasource.dataSourceProperties.databaseName=mydb
spring.datasource.username=root
spring.datasource.password=root

Then just add

@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

I created a test project here: https://github.com/ydemartino/spring-boot-hikaricp

SELECT * 
FROM table1 
INNER JOIN table2
      ON table1.primaryKey=table2.table1Id
INNER JOIN table3
      ON table1.primaryKey=table3.table1Id

$url = 'http://legis.senado.leg.br/dadosabertos/materia/tramitando';
$xml = file_get_contents("xml->{$url}");
$xml = simplexml_load_file($url);

Try this:

if (!variable && typeof variable === "object") {
    // variable is null
}

This takes Test.txt with headers and appends Test1.txt and Test2.txt and writes results to Testresult.txt file after stripping headers from second and third files respectively:

type C:\Test.txt > C:\Testresult.txt && more +1 C:\Test1.txt >> C:\Testresult.txt && more +1 C:\Test2.txt >> C:\Testresult.txt

Using only CSS it is not possible at all to add links :) It is not possible to link a background-image, nor a part of it, using HTML/CSS. However, it can be staged using this method:

<div class="wrapWithBackgroundImage">
    <a href="#" class="invisibleLink"></a>
</div>

.wrapWithBackgroundImage {
    background-image: url(...);
}
.invisibleLink {
    display: block;
    left: 55px; top: 55px;
    position: absolute;
    height: 55px width: 55px;
}

With custom colours (for example, dark red, dark green and dark blue):

import random

COLORS = [(139, 0, 0), 
          (0, 100, 0),
          (0, 0, 139)]

def random_color():
    return random.choice(COLORS)

On some mobiles like mine (MIUI Redmi 3) you can just add specific Application on list where application doesnt stop when you terminate applactions in Task Manager (It will stop but it will start again)

Just go to Settings>PermissionsAutostart

Instead of writing the very long:

=OFFSET(INDIRECT(ADDRESS(ROW(), COLUMN())),0,-1)

You can simply write:

=OFFSET(*Name of your Cell*,0,-1)

Thus for example you can write into Cell B2:

=OFFSET(B2,0,-1)

to reference to cell B1

Still thanks Jason Young!! I would have never come up with this solution without your answer!

Agree with the Money pattern: Handling currencies is just too cumbersome when you use decimals.

If you create a Currency-class, you can then put all the logic relating to money there, including a correct ToString()-method, more control of parsing values and better control of divisions.

Also, with a Currency class, there is no chance of unintentionally mixing money up with other data.

This answer fails in a couple of edge cases (see comments). The accepted solution above will handle these. str.splitlines() is the way to go. I will leave this answer nevertheless as reference.

Old (incorrect) answer:

s =  \
"""line1
line2
line3
"""

lines = s.split('\n')
print(lines)
for line in lines:
    print(line)

Use Java's replaceAll(String regex, String replacement)

For example, Use a substitution char for the quotes and then replace that char with \"

String newstring = String.replaceAll("%","\"");

or replace all instances of \" with \\\"

String newstring = String.replaceAll("\"","\\\"");

When we declare static member class inside a class, it is known as top level nested class or a static nested class. It can be demonstrated as below :

class Test{
    private static int x = 1;
        static class A{
        private static int y = 2;
        public static int getZ(){
            return B.z+x;
        }
    }
    static class B{
        private static int z = 3;
        public static int getY(){
            return A.y;
        }
    }
}

class TestDemo{
     public static void main(String[] args){
        Test t = new Test();
        System.out.println(Test.A.getZ());
        System.out.println(Test.B.getY());
    }
}

When we declare non-static member class inside a class it is known as inner class. Inner class can be demonstrated as below :

    class Test{
        private int i = 10;
        class A{
            private int i =20;
            void display(){
            int i = 30;
            System.out.println(i);
            System.out.println(this.i);
            System.out.println(Test.this.i);
        }
    }
}

First add Dimension component:

import { AppRegistry, Text, View,Dimensions } from 'react-native';

Second define Variables:

var height = Dimensions.get('window').height;
var width = Dimensions.get('window').width;

Third put it in your stylesheet:

textOutputView: {
    flexDirection:'row',
    paddingTop:20,
    borderWidth:1,
    borderColor:'red',
    height:height*0.25,
    backgroundColor:'darkgrey',
    justifyContent:'flex-end'
}

Actually in this example I wanted to make responsive view and wanted to view only 0.25 of the screen view so I multiplied it with 0.25, if you wanted 100% of the screen don't multiply it with any thing like this:

textOutputView: {
    flexDirection:'row',
    paddingTop:20,
    borderWidth:1,
    borderColor:'red',
    height:height,
    backgroundColor:'darkgrey',
    justifyContent:'flex-end'
}

I created a more comprehensive and cleaner version that some people might find useful for remembering which name corresponds to which value. I used Chrome Dev Tool's color code and labels are organized symmetrically to pick up analogies faster:

• Note 1: clientLeft also includes the width of the vertical scroll bar if the direction of the text is set to right-to-left (since the bar is displayed to the left in that case)

• Note 2: the outermost line represents the closest positioned parent (an element whose position property is set to a value different than static or initial). Thus, if the direct container isn’t a positioned element, then the line doesn’t represent the first container in the hierarchy but another element higher in the hierarchy. If no positioned parent is found, the browser will take the html or body element as reference

Hope somebody finds it useful, just my 2 cents ;)

For those of you who faced this issue while creating a controller through the context menu, reopening Visual Studio as an administrator fixed it.

From the docs:

Another common operation is the use of boolean vectors to filter the data. The operators are: | for or, & for and, and ~ for not. These must be grouped by using parentheses.

http://pandas.pydata.org/pandas-docs/version/0.15.2/indexing.html#boolean-indexing

Try:

alldata_balance = alldata[(alldata[IBRD] !=0) | (alldata[IMF] !=0)]

Looks like you can construct the link to the NDK that you want and download it from dl.google.com:

Linux example:
http://dl.google.com/android/ndk/android-ndk-r9b-linux-x86.tar.bz2 http://dl.google.com/android/ndk/android-ndk-r9b-linux-x86_64.tar.bz2

OS X example:
http://dl.google.com/android/ndk/android-ndk-r9b-darwin-x86.tar.bz2 http://dl.google.com/android/ndk/android-ndk-r9b-darwin-x86_64.tar.bz2

Windows example:
http://dl.google.com/android/ndk/android-ndk-r9b-windows.zip

Extensions up to r10b:
.tar.bz2 for linux / os x and .zip for windows.

Since r10c the extensions have changed to:
.bin for linux / os x and .exe for windows

Since r11:

.zip for linux and OS X as well, a new URL base, and no 32 bit versions for OS X and linux.

https://dl.google.com/android/repository/android-ndk-r11-linux-x86_64.zip

Like what Volker mentioned, nested structs is the way to go. But if you really do not want nested structs, you can override the UnmarshalJSON func.

https://play.golang.org/p/dqn5UdqFfJt

type A struct {
    FooBar string // takes foo.bar
    FooBaz string // takes foo.baz
    More   string 
}

func (a *A) UnmarshalJSON(b []byte) error {

    var f interface{}
    json.Unmarshal(b, &f)

    m := f.(map[string]interface{})

    foomap := m["foo"]
    v := foomap.(map[string]interface{})

    a.FooBar = v["bar"].(string)
    a.FooBaz = v["baz"].(string)
    a.More = m["more"].(string)

    return nil
}

Please ignore the fact that I'm not returning a proper error. I left that out for simplicity.

UPDATE: Correctly retrieving "more" value.

The options for popen can be used in call

args, 
bufsize=0, 
executable=None, 
stdin=None, 
stdout=None, 
stderr=None, 
preexec_fn=None, 
close_fds=False, 
shell=False, 
cwd=None, 
env=None, 
universal_newlines=False, 
startupinfo=None, 
creationflags=0

So...

subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml",  "/tmp/video_xml"], stdout=myoutput)

Then you can do what you want with myoutput (which would need to be a file btw).

Also, you can do something closer to a piped output like this.

dmesg | grep hda

would be:

p1 = Popen(["dmesg"], stdout=PIPE)
p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]

There's plenty of lovely, useful info on the python manual page.

I got a text file originally generated on a Windows Machine by way of a Mac user and needed to import it into a Linux MySQL DB using the load data command.

Although VIM displayed the '^M' character, none of the above worked for my particular problem, the data would import but was always corrupted in some way. The solution was pretty easy in the end (after much frustration).

Solution: Executing dos2unix TWICE on the same file did the trick! Using the file command shows what is happening along the way.

$ file 'file.txt'
file.txt: ASCII text, with CRLF, CR line terminators

$ dos2unix 'file.txt'
dos2unix: converting file file.txt to UNIX format ...
$ file 'file.txt'
file.txt: ASCII text, with CRLF line terminators

$ dos2unix 'file.txt'
dos2unix: converting file file.txt to UNIX format ...
$ file 'file.txt'
file.txt: ASCII text

And the final version of the file imported perfectly into the database.

I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)

It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):

Dim d As dictionary
Set d = New dictionary

d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection

You can also use the VBA Collection object if your needs are simpler and you just want string keys.

I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)

If you wanna do it in case-insensitive way, this is better:

System.out.println(test.matches("^(?i)(https?|ftp)://.*$")); 

Check TeeChart for Javascript

• Free for non-commercial use.

• Includes plugins for jQuery, Node.js, WordPress, Drupal, Joomla, Microsoft TypeScript, etc...

• Interactive demos here and here.

• Some screenshots of some of the demos:

you can do this without jQuery:

    var form=document.getElementById('form-id');//retrieve the form as a DOM element

    var input = document.createElement('input');//prepare a new input DOM element
    input.setAttribute('name', inputName);//set the param name
    input.setAttribute('value', inputValue);//set the value
    input.setAttribute('type', inputType)//set the type, like "hidden" or other

    form.appendChild(input);//append the input to the form

    form.submit();//send with added input

use jquery :  $("#id").css("background","red");

You may simple get it with s3cmd command:

s3cmd get --recursive --continue s3://test-bucket local-directory/

I've found that (currently) Chrome (Version 52.0.2743.116 m) has tons of quirks and issues with css column-count regarding overflow items and absolute positioned elements inside items, especially with some dimensions transitions..

it's a total mess and cannot be fix, so I tried tackling this through simple javascript, and had created a library which does that - https://github.com/yairEO/listBreaker

Demo page

VOLUME is used in Dockerfile to expose the volume to be used by other containers. Example, create Dockerfile as:

FROM ubuntu:14.04

RUN mkdir /myvol  
RUN echo "hello world" > /myvol/greeting  
VOLUME /myvol

build the image:

$ docker build -t testing_volume .

Run the container, say container1:

$ docker run -it <image-id of above image> bash

Now run another container with volumes-from option as (say-container2)

$ docker run -it --volumes-from <id-of-above-container> ubuntu:14.04 bash

You will get all data from container1 /myvol directory into container2 at same location.

-v option is given at run time of container which is used to mount container's directory on host. It is simple to use, just provide -v option with argument as <host-path>:<container-path>. The whole command may be as $ docker run -v <host-path>:<container-path> <image-id>

Linq to sql has no support for Count(Distinct ...). You therefore have to map a .NET method in code onto a Sql server function (thus Count(distinct.. )) and use that.

btw, it doesn't help if you post pseudo code copied from a toolkit in a format that's neither VB.NET nor C#.

Wrap your AND logic in parenthesis, like this:

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND (date='$Date_Today' OR date='$Date_Yesterday' OR date='$Date_TwoDaysAgo' OR date='$Date_ThreeDaysAgo' OR date='$Date_FourDaysAgo' OR date='$Date_FiveDaysAgo' OR date='$Date_SixDaysAgo' OR date='$Date_SevenDaysAgo')");

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

Use execute_script, here's a python example:

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://stackoverflow.com/questions/7794087/running-javascript-in-selenium-using-python") 
driver.execute_script("document.getElementsByClassName('comment-user')[0].click()")

this will help all of you to find your own correct details use

npm ls dist-tag

this will then show the correct info so you don't guess the version file location etc

enjoy :)

To avoid confusion (as there seems to be some in the comments). Assuming you are on Jupyter:

%matplotlib inline > displays the plots INSIDE the notebook

sns.plt.show() > displays the plots OUTSIDE of the notebook

%matplotlib inline will OVERRIDE sns.plt.show() in the sense that plots will be shown IN the notebook even when sns.plt.show() is called.

And yes, it is easy to include the line in to your config:

Automatically run %matplotlib inline in IPython Notebook

But it seems a better convention to keep it together with imports in the actual code.

in order to know the phone resolution simply create a image with label mdpi, hdpi, xhdpi and xxhdpi. put these images in respective folder like mdpi, hdpi, xhdpi and xxhdpi. create a image view in layout and load this image. the phone will load the respective image from a specific folder. by this you will get the phone resolution or *dpi it is using.

You could use the object data type:

>>> import numpy
>>> s = numpy.array(['a', 'b', 'dude'], dtype='object')
>>> s[0] += 'bcdef'
>>> s
array([abcdef, b, dude], dtype=object)

if you're submitting to the same page where the form is you could write the form tags with out an action and it will submit, like this

<form method='post'> <!-- you can see there is no action here-->

Ideally you shouldn't be splitting strings in T-SQL at all.

Barring that change, on older versions before SQL Server 2016, create a split function:

CREATE FUNCTION dbo.SplitStrings
(
    @List      nvarchar(max), 
    @Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
  RETURN ( WITH x(x) AS
    (
      SELECT CONVERT(xml, N'<root><i>' 
        + REPLACE(@List, @Delimiter, N'</i><i>') 
        + N'</i></root>')
    )
    SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
      FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
  );
GO

Now you can say:

DECLARE @Values varchar(1000);

SET @Values = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN dbo.SplitStrings(@Values, ',') AS s
    ON s.Item = foo.myField;

On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM() to take away any leading spaces:

DECLARE @Values varchar(1000) = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN STRING_SPLIT(@Values, ',') AS s
    ON LTRIM(s.value) = foo.myField;

You've encountered a local time discontinuity:

When local standard time was about to reach Sunday, 1. January 1928, 00:00:00 clocks were turned backward 0:05:52 hours to Saturday, 31. December 1927, 23:54:08 local standard time instead

This is not particularly strange and has happened pretty much everywhere at one time or another as timezones were switched or changed due to political or administrative actions.

As you're using Windows, installation should automatically edit the %PATH% variable. Therefore, I suspect you simply need to reboot your system after installing.

In SQL Server Management Studio (SSMS):

You can also right click your database in the Object Explorer and go to Properties. From there, go to Options. Scroll all the way down and set Restrict Access to SINGLE_USER. Change your database name, then go back in and set it back to MULTI_USER.

I fixed this issue on my debian GNU/Linux system by overiding system rules that way :

mv  /etc/udev/rules.d/51-android.rules /etc/udev/rules.d/99-android.rules

I used contents from files linked at : http://rootzwiki.com/topic/258-udev-rules-for-any-device-no-more-starting-adb-with-sudo/

The six library helps with writing code that is compatible with both python 2.5+ and python 3. It has an iteritems method that will work in both python 2 and 3. Example:

import six

d = dict( foo=1, bar=2 )

for k, v in six.iteritems(d):
    print(k, v)

This rule

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o producer.o consumer.o AddRemove.o

is wrong. It says to create a file named producer.o (with -o producer.o), but you want to create a file named main. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET:

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o $@ producer.o consumer.o AddRemove.o

As Shahbaz rightly points out, the gmake professionals would also use $^ which expands to all the prerequisites in the rule. In general, if you find yourself repeating a string or name, you're doing it wrong and should use a variable, whether one of the built-ins or one you create.

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o $@ $^

This example shows how to publish log files in JBoss through a rest resource. Note the get method uses the StreamingOutput interface to stream the content of the log file.

@Path("/logs/")
@RequestScoped
public class LogResource {

private static final Logger logger = Logger.getLogger(LogResource.class.getName());
@Context
private UriInfo uriInfo;
private static final String LOG_PATH = "jboss.server.log.dir";

public void pipe(InputStream is, OutputStream os) throws IOException {
    int n;
    byte[] buffer = new byte[1024];
    while ((n = is.read(buffer)) > -1) {
        os.write(buffer, 0, n);   // Don't allow any extra bytes to creep in, final write
    }
    os.close();
}

@GET
@Path("{logFile}")
@Produces("text/plain")
public Response getLogFile(@PathParam("logFile") String logFile) throws URISyntaxException {
    String logDirPath = System.getProperty(LOG_PATH);
    try {
        File f = new File(logDirPath + "/" + logFile);
        final FileInputStream fStream = new FileInputStream(f);
        StreamingOutput stream = new StreamingOutput() {
            @Override
            public void write(OutputStream output) throws IOException, WebApplicationException {
                try {
                    pipe(fStream, output);
                } catch (Exception e) {
                    throw new WebApplicationException(e);
                }
            }
        };
        return Response.ok(stream).build();
    } catch (Exception e) {
        return Response.status(Response.Status.CONFLICT).build();
    }
}

@POST
@Path("{logFile}")
public Response flushLogFile(@PathParam("logFile") String logFile) throws URISyntaxException {
    String logDirPath = System.getProperty(LOG_PATH);
    try {
        File file = new File(logDirPath + "/" + logFile);
        PrintWriter writer = new PrintWriter(file);
        writer.print("");
        writer.close();
        return Response.ok().build();
    } catch (Exception e) {
        return Response.status(Response.Status.CONFLICT).build();
    }
}    

}

Much simpler using only SimpleDateFormat, without passing all the parameters individual:

    String FORMATER = "yyyy-MM-dd'T'HH:mm:ss'Z'";

    DateFormat format = new SimpleDateFormat(FORMATER);

    Date date = new Date();
    XMLGregorianCalendar gDateFormatted =
        DatatypeFactory.newInstance().newXMLGregorianCalendar(format.format(date));

Full example here.

Note: This is working only to remove the last 2 fields: milliseconds and timezone or to remove the entire time component using formatter yyyy-MM-dd.

OK, so I think there is no sufficient answer for general camera preview stretching problem. Or at least I didn't find one. My app also suffered this stretching syndrome and it took me a while to puzzle together a solution from all the user answers on this portal and internet.

I tried @Hesam's solution but it didn't work and left my camera preview majorly distorted.

First I show the code of my solution (the important parts of the code) and then I explain why I took those steps. There is room for performance modifications.

Main activity xml layout:

<RelativeLayout 
    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    <FrameLayout
        android:id="@+id/camera_preview"
        android:layout_centerInParent="true"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

My commentary:

The point of all this is, that although you calculate the optimal camera size in getOptimalPreviewSize() you only pick the closest ratio to fit your screen. So unless the ratio is exactly the same the preview will stretch.

Why will it stretch? Because your FrameLayout camera preview is set in layout.xml to match_parent in width and height. So that is why the preview will stretch to full screen.

What needs to be done is to set camera preview layout width and height to match the chosen camera size ratio, so the preview keeps its aspect ratio and won't distort.

I tried to use the CameraPreview class to do all the calculations and layout changes, but I couldn't figure it out. I tried to apply this solution, but SurfaceView doesn't recognize getChildCount () or getChildAt (int index). I think, I got it working eventually with a reference to maLayoutPreview, but it was misbehaving and applied the set ratio to my whole app and it did so after first picture was taken. So I let it go and moved the layout modifications to the MainActivity.

In CameraPreview I changed prSupportedPreviewSizes and getOptimalPreviewSize() to public so I can use it in MainActivity. Then I needed the display dimensions (minus the navigation/status bar if there is one) and chosen optimal camera size. I tried to get the RelativeLayout (or FrameLayout) size instead of display size, but it was returning zero value. This solution didn't work for me. The layout got it's value after onWindowFocusChanged (checked in the log).

So I have my methods for calculating the layout dimensions to match the aspect ratio of chosen camera size. Now you just need to set LayoutParams of your camera preview layout. Change the width, height and center it in parent.

There are two choices how to calculate the preview dimensions. Either you want it to fit the screen with black bars (if windowBackground is set to null) on the sides or top/bottom. Or you want the preview zoomed to full screen. I left comment with more information in calcCamPrevDimensions().

For null values in the dataframe of pyspark

This is another way to do it, very similar to Manoj Govindan's answer above:

import re
regex_http_          = re.compile(r'^HTTP_.+$')
regex_content_type   = re.compile(r'^CONTENT_TYPE$')
regex_content_length = re.compile(r'^CONTENT_LENGTH$')

request_headers = {}
for header in request.META:
    if regex_http_.match(header) or regex_content_type.match(header) or regex_content_length.match(header):
        request_headers[header] = request.META[header]

That will also grab the CONTENT_TYPE and CONTENT_LENGTH request headers, along with the HTTP_ ones. request_headers['some_key] == request.META['some_key'].

Modify accordingly if you need to include/omit certain headers. Django lists a bunch, but not all, of them here: https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpRequest.META

Django's algorithm for request headers:

1. Replace hyphen - with underscore _
2. Convert to UPPERCASE.
3. Prepend HTTP_ to all headers in original request, except for CONTENT_TYPE and CONTENT_LENGTH.

The values of each header should be unmodified.

jQuery 1.4 also includes a .delay( duration, [ queueName ] ) method if you only need it to trigger once and have already started using that version.

$('#foo').slideUp(300).delay(800).fadeIn(400);

http://api.jquery.com/delay/

Ooops....my mistake you were looking for an event to continue triggering. I'll leave this here, someone may find it helpful.

Days Class

Using the Days class with the withTimeAtStartOfDay method should work:

Days.daysBetween(start.withTimeAtStartOfDay() , end.withTimeAtStartOfDay() ).getDays() 

For limited set of values matplotlib is fine. But when you have lots of values the tooltip starts to overlap over other data points. But with limited space you can't ignore the values. Hence it's better to zoom out or zoom in.

Using plotly

import plotly.express as px
df = px.data.tips()

df = px.data.gapminder().query("year==2007 and continent=='Americas'")


fig = px.scatter(df, x="gdpPercap", y="lifeExp", text="country", log_x=True, size_max=100, color="lifeExp")
fig.update_traces(textposition='top center')
fig.update_layout(title_text='Life Expectency', title_x=0.5)
fig.show()

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

Perhaps a temporary table will do what you want.

CREATE TEMPORARY TABLE SalesSummary (
product_name VARCHAR(50) NOT NULL
, total_sales DECIMAL(12,2) NOT NULL DEFAULT 0.00
, avg_unit_price DECIMAL(7,2) NOT NULL DEFAULT 0.00
, total_units_sold INT UNSIGNED NOT NULL DEFAULT 0
) ENGINE=MEMORY;

INSERT INTO SalesSummary
(product_name, total_sales, avg_unit_price, total_units_sold)
SELECT 
  p.name
  , SUM(oi.sales_amount)
  , AVG(oi.unit_price)
  , SUM(oi.quantity_sold)
FROM OrderItems oi
INNER JOIN Products p
    ON oi.product_id = p.product_id
GROUP BY p.name;

/* Just output the table */
SELECT * FROM SalesSummary;

/* OK, get the highest selling product from the table */
SELECT product_name AS "Top Seller"
FROM SalesSummary
ORDER BY total_sales DESC
LIMIT 1;

/* Explicitly destroy the table */
DROP TABLE SalesSummary;

If jQuery is loading asynchronously, you can wait till it is defined, checking for it every period of time:

(function() {
    var a = setInterval( function() {
        if ( typeof window.jQuery === 'undefined' ) {
            return;
        }
        clearInterval( a );

        console.log( 'jQuery is loaded' ); // call your function with jQuery instead of this
    }, 500 );
})();

This method can be used for any variable, you are waiting to appear.

In the first case, the data are passed to the script via GET, in the second via POST.

http://docs.jquery.com/Ajax/load#urldatacallback

I don't think there are limits to the data size, but the completition of the remote call will of course take longer with great amount of data.

The difference between cache and persist operations is purely syntactic. cache is a synonym of persist or persist(MEMORY_ONLY), i.e. cache is merely persist with the default storage level MEMORY_ONLY

But Persist() We can save the intermediate results in 5 storage levels.

1. MEMORY_ONLY
2. MEMORY_AND_DISK
3. MEMORY_ONLY_SER
4. MEMORY_AND_DISK_SER
5. DISK_ONLY

/** * Persist this RDD with the default storage level (MEMORY_ONLY). */
def persist(): this.type = persist(StorageLevel.MEMORY_ONLY)

/** * Persist this RDD with the default storage level (MEMORY_ONLY). */
def cache(): this.type = persist()

see more details here...

Caching or persistence are optimization techniques for (iterative and interactive) Spark computations. They help saving interim partial results so they can be reused in subsequent stages. These interim results as RDDs are thus kept in memory (default) or more solid storage like disk and/or replicated. RDDs can be cached using cache operation. They can also be persisted using persist operation.

#persist, cache

These functions can be used to adjust the storage level of a RDD. When freeing up memory, Spark will use the storage level identifier to decide which partitions should be kept. The parameter less variants persist() and cache() are just abbreviations for persist(StorageLevel.MEMORY_ONLY).

Warning: Once the storage level has been changed, it cannot be changed again!

Warning -Cache judiciously... see ((Why) do we need to call cache or persist on a RDD)

Just because you can cache a RDD in memory doesn’t mean you should blindly do so. Depending on how many times the dataset is accessed and the amount of work involved in doing so, recomputation can be faster than the price paid by the increased memory pressure.

It should go without saying that if you only read a dataset once there is no point in caching it, it will actually make your job slower. The size of cached datasets can be seen from the Spark Shell..

Listing Variants...

def cache(): RDD[T]
 def persist(): RDD[T]
 def persist(newLevel: StorageLevel): RDD[T]

See below example :

val c = sc.parallelize(List("Gnu", "Cat", "Rat", "Dog", "Gnu", "Rat"), 2)
     c.getStorageLevel
     res0: org.apache.spark.storage.StorageLevel = StorageLevel(false, false, false, false, 1)
     c.cache
     c.getStorageLevel
     res2: org.apache.spark.storage.StorageLevel = StorageLevel(false, true, false, true, 1)

Note : Due to the very small and purely syntactic difference between caching and persistence of RDDs the two terms are often used interchangeably.

See more visually here....

Cache

Caching can improve the performance of your application to a great extent.

The general format, from the @link section of the javadoc documentation, is:

Examples

Method in the same class:

/** See also {@link #myMethod(String)}. */
void foo() { ... }

Method in a different class, either in the same package or imported:

/** See also {@link MyOtherClass#myMethod(String)}. */
void foo() { ... }

Method in a different package and not imported:

/** See also {@link com.mypackage.YetAnotherClass#myMethod(String)}. */
void foo() { ... }

Label linked to method, in plain text rather than code font:

/** See also this {@linkplain #myMethod(String) implementation}. */
void foo() { ... }

A chain of method calls, as in your question. We have to specify labels for the links to methods outside this class, or we get getFoo().Foo.getBar().Bar.getBaz(). But these labels can be fragile during refactoring -- see "Labels" below.

/**
 * A convenience method, equivalent to 
 * {@link #getFoo()}.{@link Foo#getBar() getBar()}.{@link Bar#getBaz() getBaz()}.
 * @return baz
 */
public Baz fooBarBaz()

Labels

Automated refactoring may not affect labels. This includes renaming the method, class or package; and changing the method signature.

Therefore, provide a label only if you want different text than the default.

For example, you might link from human language to code:

/** You can also {@linkplain #getFoo() get the current foo}. */
void setFoo( Foo foo ) { ... }

Or you might link from a code sample with text different than the default, as shown above under "A chain of method calls." However, this can be fragile while APIs are evolving.

Type erasure and #member

If the method signature includes parameterized types, use the erasure of those types in the javadoc @link. For example:

int bar( Collection<Integer> receiver ) { ... }

/** See also {@link #bar(Collection)}. */
void foo() { ... }

The ZERO WIDTH SPACE character is inserted when you use jQuery to add elements using DOM manipulation functions like .before() and .after()

I've run into this when adding hidden modal dialog frames at the end of my document and then finding that the ZERO WIDTH SPACE screws up the layout down there, adding unwanted space.

The quick fix was to insert it before the footer, not after it. Its hidden anyway.

I can't find anything in jQuery that does this:

https://github.com/jquery/jquery/blob/master/src/manipulation.js

So it might be the browser that adds it.

Detailed Step by Step instructions I followed to achieve this

• Download bouncycastle JAR from http://repo2.maven.org/maven2/org/bouncycastle/bcprov-ext-jdk15on/1.46/bcprov-ext-jdk15on-1.46.jar or take it from the "doc" folder.
• Configure BouncyCastle for PC using one of the below methods.
  • Adding the BC Provider Statically (Recommended)
    • Copy the bcprov-ext-jdk15on-1.46.jar to each
      • D:\tools\jdk1.5.0_09\jre\lib\ext (JDK (bundled JRE)
      • D:\tools\jre1.5.0_09\lib\ext (JRE)
      • C:\ (location to be used in env variable)
    • Modify the java.security file under
      • D:\tools\jdk1.5.0_09\jre\lib\security
      • D:\tools\jre1.5.0_09\lib\security
      • and add the following entry
        • security.provider.7=org.bouncycastle.jce.provider.BouncyCastleProvider
    • Add the following environment variable in "User Variables" section
      • CLASSPATH=%CLASSPATH%;c:\bcprov-ext-jdk15on-1.46.jar
  • Add bcprov-ext-jdk15on-1.46.jar to CLASSPATH of your project and Add the following line in your code
    • Security.addProvider(new BouncyCastleProvider());
• Generate the Keystore using Bouncy Castle
  • Run the following command
    • keytool -genkey -alias myproject -keystore C:/myproject.keystore -storepass myproject -storetype BKS -provider org.bouncycastle.jce.provider.BouncyCastleProvider
  • This generates the file C:\myproject.keystore
  • Run the following command to check if it is properly generated or not
    • keytool -list -keystore C:\myproject.keystore -storetype BKS

• Configure BouncyCastle for TOMCAT

  • Open D:\tools\apache-tomcat-6.0.35\conf\server.xml and add the following entry

    • <Connector port="8443" keystorePass="myproject" alias="myproject" keystore="c:/myproject.keystore" keystoreType="BKS" SSLEnabled="true" clientAuth="false" protocol="HTTP/1.1" scheme="https" secure="true" sslProtocol="TLS" sslImplementationName="org.bouncycastle.jce.provider.BouncyCastleProvider"/>

  • Restart the server after these changes.

• Configure BouncyCastle for Android Client
  • No need to configure since Android supports Bouncy Castle Version 1.46 internally in the provided "android.jar".
  • Just implement your version of HTTP Client (MyHttpClient.java can be found below) and set the following in code
    • SSLSocketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
  • If you don't do this, it gives an exception as below
    • javax.net.ssl.SSLException: hostname in certificate didn't match: <192.168.104.66> !=
  • In production mode, change the above code to
    • SSLSocketFactory.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);

How to invoke the above code in your Activity class:

DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpResponse response = client.execute(...);

All you needed was a plus :)

$("#Restaurant_Name").keyup(function(){
        var Text = $(this).val();
        Text = Text.toLowerCase();
        var regExp = /\s+/g;
        Text = Text.replace(regExp,'-');
        $("#Restaurant_Slug").val(Text);        
});

Get a list of properties from model using _.keys(), and use _.pick() to extract the properties from credentials to a new object:

var model = {
   fname:null,
   lname:null
};

var credentials = {
    fname:"xyz",
    lname:"abc",
    age:23
};

var result = _.pick(credentials, _.keys(model));

console.log(result);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.16.4/lodash.min.js"></script>

If you don't want to use Lodash, you can use Object.keys(), and Array.prototype.reduce():

var model = {
   fname:null,
   lname:null
};

var credentials = {
    fname:"xyz",
    lname:"abc",
    age:23
};

var result = Object.keys(model).reduce(function(obj, key) {
  obj[key] = credentials[key];
  return obj;
}, {});

console.log(result);

Tested with Chromium 40 and Firefox 36

Very basic example with $lookup.

db.getCollection('users').aggregate([
    {
        $lookup: {
            from: "userinfo",
            localField: "userId",
            foreignField: "userId",
            as: "userInfoData"
        }
    },
    {
        $lookup: {
            from: "userrole",
            localField: "userId",
            foreignField: "userId",
            as: "userRoleData"
        }
    },
    { $unwind: { path: "$userInfoData", preserveNullAndEmptyArrays: true }},
    { $unwind: { path: "$userRoleData", preserveNullAndEmptyArrays: true }}
])

Here is used

 { $unwind: { path: "$userInfoData", preserveNullAndEmptyArrays: true }}, 
 { $unwind: { path: "$userRoleData", preserveNullAndEmptyArrays: true }}

Instead of

{ $unwind:"$userRoleData"} 
{ $unwind:"$userRoleData"}

Because { $unwind:"$userRoleData"} this will return empty or 0 result if no matching record found with $lookup.

I have occurred the same error look following example-

async.waterfall([function(waterCB) {
    waterCB(null);
}, function(**inputArray**, waterCB) {
    waterCB(null);
}], function(waterErr, waterResult) {
    console.log('Done');
});

In the above waterfall function, I am accepting inputArray parameter in waterfall 2nd function. But this inputArray not passed in waterfall 1st function in waterCB.

Cheak your function parameters Below are a correct example.

async.waterfall([function(waterCB) {
    waterCB(null, **inputArray**);
}, function(**inputArray**, waterCB) {
    waterCB(null);
}], function(waterErr, waterResult) {
    console.log('Done');
});

Thanks

Bootstrap's responsive image class sets max-width to 100%. This limits its size, but does not force it to stretch to fill parent elements larger than the image itself. You'd have to use the width attribute to force upscaling.

Yes VBA is the way to go.

But, if you don't need to have a cell with formula that auto-counts/updates the number of cells with a particular colour, an alternative is simply to use the 'Find and Replace' function and format the cell to have the appropriate colour fill.

Hitting 'Find All' will give you the total number of cells found at the bottom left of the dialogue box.

This becomes especially useful if your search range is massive. The VBA script will be very slow but the 'Find and Replace' function will still be very quick.

If it helps there is also a jar-versions.xml in my JBoss installation in JBoss root folder. This doesn't require you to wget or jar xvf.

E.g.

$  grep jboss-system.jar /opt/jboss-5.1.0.GA/jar-versions.xml | fold
  <jar name="jboss-system.jar" specVersion="5.1.0.GA" specVendor="JBoss (http://
www.jboss.org/)" specTitle="JBoss" implVersion="5.1.0.GA (build: SVNTag=JBoss_5_
1_0_GA date=200905221634)" implVendor="JBoss Inc." implTitle="JBoss [The Oracle]

Make sure to enable the use of shortcodes in text widgets.

// To enable the use, add this in your *functions.php* file:
add_filter( 'widget_text', 'do_shortcode' );

// and then you can use it in any PHP file:  
<?php echo do_shortcode('[YOUR-SHORTCODE-NAME/TAG]'); ?>

Check the documentation for more.

This will horizontally center an inline-block element without needing to modify its parent's styles:

  display: inline-block;
  position: relative;
  // Move the element to the left by 50% of the container's width
  left: 50%; 
  // Calculates 50% of the element's width, and moves it by that
  // amount across the X-axis to the left
  transform: translateX(-50%);

For your specific example, if you want to do a one-to-one relationship, you should change the next code in ReleaseDateType model:

@Column(nullable = true) 
private Integer media_Id;

for:

@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name="CACHE_MEDIA_ID", nullable=true)
private CacheMedia cacheMedia ;

and in CacheMedia model you need to add:

@OneToOne(cascade=ALL, mappedBy="ReleaseDateType")
private ReleaseDateType releaseDateType;

then in your repository you should replace:

@Query("Select * from A a  left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();

by:

//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedia_Id(Integer id); 

or by:

@Query("FROM ReleaseDateType AS rdt WHERE cm.rdt.cacheMedia.id = ?1")    //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);

Or if you prefer to do a @OneToMany and @ManyToOne relation, you should change the next code in ReleaseDateType model:

@Column(nullable = true) 
private Integer media_Id;

for:

@OneToMany(cascade=ALL, mappedBy="ReleaseDateType")
private List<CacheMedia> cacheMedias ;

and in CacheMedia model you need to add:

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="RELEASE_DATE_TYPE_ID", nullable=true)
private ReleaseDateType releaseDateType;

then in your repository you should replace:

@Query("Select * from A a  left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();

by:

//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedias_Id(Integer id); 

or by:

@Query("FROM ReleaseDateType AS rdt LEFT JOIN rdt.cacheMedias AS cm WHERE cm.id = ?1")    //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);

It's working for me ,

Add below code into the info.plist file ,

 <key>UIStatusBarHidden</key>
 <false/>
 <key>UIViewControllerBasedStatusBarAppearance</key>

Hopes this is work for some one .

This did the trick for me: (solution from the msdn forum)

goto Controlpanel --> Administrative tools-->Component Services -->computers --> myComputer -->DCOM Config --> Microsoft Excel Application.

right click to get properties dialog. Goto Security tab and customize permissions accordingly.

In Launch and Application Permissions, select Customize, Edit. Add the user / group that calls the application.

wait until the process is over ...

while(webview.getProgress()< 100){}
progressBar.setVisibility(View.GONE);

For me, after I've removed Xcode, I have to switch active developer path as follows: sudo xcode-select -s /

see below code it may help you.

String q = "SELECT * FROM customer";
Cursor mCursor = mDb.rawQuery(q, null);

or

String q = "SELECT * FROM customer WHERE _id = " + customerDbId  ;
Cursor mCursor = mDb.rawQuery(q, null);

You can do it by making form and displaying it using ShowDialogBox....

Form.ShowDialog Method - Shows the form as a modal dialog box.

Example:

public void ShowMyDialogBox()
{
   Form2 testDialog = new Form2();

   // Show testDialog as a modal dialog and determine if DialogResult = OK.
   if (testDialog.ShowDialog(this) == DialogResult.OK)
   {
      // Read the contents of testDialog's TextBox.
      this.txtResult.Text = testDialog.TextBox1.Text;
   }
   else
   {
      this.txtResult.Text = "Cancelled";
   }
   testDialog.Dispose();
}

The solution with copying 32-bit libs over to 64-bit did not work for me. What worked was unchecking Target Platform Prefer 32-bit check mark in project properties.

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

#ifndef <token>
/* code */
#else
/* code to include if the token is defined */
#endif

#ifndef checks whether the given token has been #defined earlier in the file or in an included file; if not, it includes the code between it and the closing #else or, if no #else is present, #endif statement. #ifndef is often used to make header files idempotent by defining a token once the file has been included and checking that the token was not set at the top of that file.

#ifndef _INCL_GUARD
#define _INCL_GUARD
#endif

The best solution is toString (as stated above):

function getRealObjectType(obj: {}): string {
    return Object.prototype.toString.call(obj).match(/\[\w+ (\w+)\]/)[1].toLowerCase();
}

FAIR WARNING: toString considers NaN a number so you must manually safeguard later with Number.isNaN(value).

The other solution suggested, using Object.getPrototypeOf fails with null and undefined

UI-Router is a project that can help: https://github.com/angular-ui/ui-router One of it's features is Multiple Named Views

UI-Router has many features and i recommend you using it if you're working on an advanced app.

Check documentation of Multiple Named Views here.

In case you need to parse it from a file, I find the best solution to use a HashMap<String, String> to use it inside your java code for better manipultion.

Try out this code:

public HashMap<String, String> myMethodName() throws FileNotFoundException
{
    String path = "absolute path to your file";
    BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

    Gson gson = new Gson();
    HashMap<String, String> json = gson.fromJson(bufferedReader, HashMap.class);
    return json;
}

func getAppVersion() -> String {
    let dictionary = Bundle.main.infoDictionary!
    let versionValue = dictionary["CFBundleShortVersionString"] ?? "0"
    let buildValue = dictionary["CFBundleVersion"] ?? "0"
    return "\(versionValue) (build \(buildValue))"
}

Based on @rajat chauhan answer without forced cast to String.

The git will ignore the files matched .gitignore pattern after you add it to .gitignore.

But the files already existed in repository will be still in.

use git rm files_ignored; git commit -m 'rm no use files' to delete ignored files.

I wanted to add that I encountered this error when opening designer file in WinForms app. My issue was that one of the references in the project was referencing itself. Apparently this can happen as mentioned here

https://social.msdn.microsoft.com/Forums/office/en-US/00aede04-d8cd-4475-8114-4b4792261052/winforms-designer-error-hresult-efail-has-been-returned-from-a-call-to-a-com-component

I removed the reference and it is working fine.

I'm not sure I understand you completely, but if you wish to get the absolute file path provided that you know the relative file name, you can always do this:

System.out.println("File path: " + new File("Your file name").getAbsolutePath());

The File class has several more methods you might find useful.

TreeMap sorts by the key natural ordering. The keys should implement Comparable or be compatible with a Comparator (if you passed one instance to constructor). In you case, Float already implements Comparable so you don't have to do anything special.

You can call keySet to retrieve all the keys in ascending order.

After some search, I've found a cleaner solution wich use the % operator.

In your YAML file :

key : 'This is the foobar var : %{foobar}'

In your ruby code :

require 'yaml'

file = YAML.load_file('your_file.yml')

foobar = 'Hello World !'
content = file['key']
modified_content = content % { :foobar => foobar }

puts modified_content

And the output is :

This is the foobar var : Hello World !

As @jschorr said in the comment, you can also add multiple variable to the value in the Yaml file :

Yaml :

key : 'The foo var is %{foo} and the bar var is %{bar} !'

Ruby :

# ...
foo = 'FOO'
bar = 'BAR'
# ...
modified_content = content % { :foo => foo, :bar => bar }

Output :

The foo var is FOO and the bar var is BAR !

You could try the following:

import matplotlib.pyplot as plt
import numpy as np

def plot_figures(figures, nrows = 1, ncols=1):
    """Plot a dictionary of figures.

    Parameters
    ----------
    figures : <title, figure> dictionary
    ncols : number of columns of subplots wanted in the display
    nrows : number of rows of subplots wanted in the figure
    """

    fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
    for ind,title in zip(range(len(figures)), figures):
        axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
        axeslist.ravel()[ind].set_title(title)
        axeslist.ravel()[ind].set_axis_off()
    plt.tight_layout() # optional



# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}

# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)

plt.show()

However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.

I hope this helps.

How can I change where Vagrant looks for its virtual hard drive?

the virtual-machine state is stored in a predefined VirtualBox folder. Copying the corresponding machine (folder) besides your vagrant-project to your other host should preserve your virtual machine state.

As found on the mailing list archive,

• http://osdir.com/ml/gnu.make.windows/2004-03/msg00063.html
• http://osdir.com/ml/gnu.make.general/2005-10/msg00064.html

one can use the filter function.

For example

ifeq ($(GCC_MINOR),$(filter $(GCC_MINOR),4 5))

filter X, A B will return those of A,B that are equal to X. Note, while this is not relevant in the above example, this is a XOR operation. I.e. if you instead have something like:

ifeq (4, $(filter 4, $(VAR1) $(VAR2)))

And then do e.g. make VAR1=4 VAR2=4, the filter will return 4 4, which is not equal to 4.

A variation that performs an OR operation instead is:

ifneq (,$(filter $(GCC_MINOR),4 5))

where a negative comparison against an empty string is used instead (filter will return en empty string if GCC_MINOR doesn't match the arguments). Using the VAR1/VAR2 example it would look like this:

ifneq (, $(filter 4, $(VAR1) $(VAR2)))

The downside to those methods is that you have to be sure that these arguments will always be single words. For example, if VAR1 is 4 foo, the filter result is still 4, and the ifneq expression is still true. If VAR1 is 4 5, the filter result is 4 5 and the ifneq expression is true.

One easy alternative is to just put the same operation in both the ifeq and else ifeq branch, e.g. like this:

ifeq ($(GCC_MINOR),4)
    @echo Supported version
else ifeq ($(GCC_MINOR),5)
    @echo Supported version
else
    @echo Unsupported version
endif

You can parse the list as a string and use of the eval builtin function to read it as a list. In this case, you will have to put single quotes into double quote (or the way around) in order to ensure successful string parse.

# declare the list arg as a string
parser.add_argument('-l', '--list', type=str)

# parse
args = parser.parse()

# turn the 'list' string argument into a list object
args.list = eval(args.list)
print(list)
print(type(list))

Testing:

python list_arg.py --list "[1, 2, 3]"

[1, 2, 3]
<class 'list'>

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

  $arr=array(

   );
  $resp=$this->Model->insert_data('emp1',$arr);
  echo "<script>alert('$resp')</script>";
  $this->insert_view();

Another possibility is to use bit sets, for which there is at least one package or you can use the built-in big package. In this case, basically you need to define a way to convert your object to an index.

You could have simply replaced

names[i] = in.nextLine(); with names[i] = in.next();

Using next() will only return what comes before a space. nextLine() automatically moves the scanner down after returning the current line.

React provides an interface for what you are trying to do via the ref attribute. Assign a component a ref, and its current attribute will be your custom component:

class Parent extends React.Class {
    constructor(props) {
        this._child = React.createRef();
    }

    componentDidMount() {
        console.log(this._child.current.someMethod()); // Prints 'bar'
    }

    render() {
        return (
            <div>
                <Child ref={this._child} />
            </div>
        );
    }
}

Note: This will only work if the child component is declared as a class, as per documentation found here: https://facebook.github.io/react/docs/refs-and-the-dom.html#adding-a-ref-to-a-class-component

Update 2019-04-01: Changed example to use a class and createRef per latest React docs.

Update 2016-09-19: Changed example to use ref callback per guidance from the ref String attribute docs.

Requirement : Accessing the static Resources (images/videos., etc.,) from outside of WEBROOT directory or from local disk

Step 1 :
Create a folder under webapps of tomcat server., let us say the folder name is myproj

Step 2 :
Under myproj create a WEB-INF folder under this create a simple web.xml

code under web.xml

<web-app>
</web-app>

Directory Structure for the above two steps

c:\programfile\apachesoftwarefoundation\tomcat\...\webapps
                                                            |
                                                            |---myproj
                                                            |   |
                                                            |   |---WEB-INF
                                                                |   |
                                                                    |---web.xml

Step 3:
Now create a xml file with name myproj.xml under the following location

c:\programfile\apachesoftwarefoundation\tomcat\conf\catalina\localhost

CODE in myproj.xml:

<Context path="/myproj/images" docBase="e:/myproj/" crossContext="false" debug="0" reloadable="true" privileged="true" /> 

Step 4:
4 A) Now create a folder with name myproj in E drive of your hard disk and create a new

folder with name images and place some images in images folder (e:myproj\images\)

Let us suppose myfoto.jpg is placed under e:\myproj\images\myfoto.jpg

4 B) Now create a folder with name WEB-INF in e:\myproj\WEB-INF and create a web.xml in WEB-INF folder

Code in web.xml

<web-app>
</web-app>

Step 5:
Now create a .html document with name index.html and place under e:\myproj

CODE under index.html Welcome to Myproj

The Directory Structure for the above Step 4 and Step 5 is as follows

E:\myproj
    |--index.html
    |
    |--images
    |     |----myfoto.jpg
    |
    |--WEB-INF
    |     |--web.xml

Step 6:
Now start the apache tomcat server

Step 7:
open the browser and type the url as follows

http://localhost:8080/myproj    

then u display the content which is provided in index.html

Step 8:
To Access the Images under your local hard disk (outside of webroot)

http://localhost:8080/myproj/images/myfoto.jpg

The arguments argc and argv of main is used as a way to send arguments to a program, the possibly most familiar way is to use the good ol' terminal where an user could type cat file. Here the word cat is a program that takes a file and outputs it to standard output (stdout).

The program receives the number of arguments in argc and the vector of arguments in argv, in the above the argument count would be two (The program name counts as the first argument) and the argument vector would contain [cat,file,null]. While the last element being a null-pointer.

Commonly, you would write it like this:

int  // Specifies that type of variable the function returns.
     // main() must return an integer
main ( int argc, char **argv ) {
     // code
     return 0; // Indicates that everything went well.
}

If your program does not require any arguments, it is equally valid to write a main-function in the following fashion:

int main() {
  // code
  return 0; // Zero indicates success, while any 
  // Non-Zero value indicates a failure/error
}

In the early versions of the C language, there was no int before main as this was implied. Today, this is considered to be an error.

On POSIX-compliant systems (and Windows), there exists the possibility to use a third parameter char **envp which contains a vector of the programs environment variables. Further variations of the argument list of the main function exists, but I will not detail it here since it is non-standard.

Also, the naming of the variables is a convention and has no actual meaning. It is always a good idea to adhere to this so that you do not confuse others, but it would be equally valid to define main as

int main(int c, char **v, char **e) {
   // code
   return 0;
}

And for your second question, there are several ways to send arguments to a program. I would recommend you to look at the exec*()family of functions which is POSIX-standard, but it is probably easier to just use system("command arg1 arg2"), but the use of system() is usually frowned upon as it is not guaranteed to work on every system. I have not tested it myself; but if there is no bash,zsh, or other shell installed on a *NIX-system, system() will fail.

Let us have List<Object> objectList which we want to cast to List<T>

public <T> List<T> list(Class<T> c, List<Object> objectList){        
    List<T> list = new ArrayList<>();       
    for (Object o : objectList){
        T t = c.cast(o);
        list.add(t);
    }
    return list;
}

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

use strncpy to make sure you have no buffer overflow.

char name[]= "whatever_you_want";
strncpy( sara.first, name, sizeof(sara.first)-1 );
sara.first[sizeof(sara.first)-1] = 0;

Consider the figure enclosed in this other question. ebp-4 is your first local variable and, seen as a dword pointer, it is the address of a 32 bit integer that has to be cleared. Maybe your source starts with

Object x = null;

span.style.fontSize = "25px";

use this

If you just want to stop further code from executing without "throwing" any error, you can temporarily override window.onerror as shown in cross-exit:

function exit(code) {
    const prevOnError = window.onerror
    window.onerror = () => {
        window.onerror = prevOnError
        return true
    }

    throw new Error(`Script termination with code ${code || 0}.`)
}

console.log("This message is logged.");
exit();
console.log("This message isn't logged.");

The configuration manager of web configuration (web.config) is obsolete. So see this https://docs.microsoft.com/en-us/dotnet/api/system.configuration.configurationmanager.appsettings?redirectedfrom=MSDN&view=dotnet-plat-ext-3.1#System_Configuration_ConfigurationManager_AppSettings

create a instance of settings

var appSettings = ConfigurationManager.AppSettings;

So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:

>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

The accepted answer of this post will cause error in the case when the string length is lest than 5. So i have a better solution. We can use this simple code :

If(str.Length <= 5, str, str.Substring(str.Length - 5))

You can test it with variable length string.

    Dim str, result As String
    str = "11!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)
    str = "I will be going to school in 2011!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)

Another simple but efficient solution i found :

str.Substring(str.Length - Math.Min(5, str.Length))

I've recently implemented the canonical map-reduce example in Akka: Word count. So it's one use case of Akka: better performance. It was more of a experiment of JRuby and Akka's actors than anything else, but it also shows that Akka is not Scala or Java only: it works on all languages on top of JVM.

Well, I figured out the way and thought to share with the people out there who might run into the same problem.

Let me start with the problem I had been facing,

I had been trying to execute a Dynamic Sql Statement that used two temporary tables I declared at the top of my stored procedure, but because that dynamic sql statment created a new scope, I couldn't use the temporary tables.

Solution:

I simply changed them to Global Temporary Variables and they worked.

Find my stored procedure underneath.

CREATE PROCEDURE RAFCustom_Room_GetRelatedProducts
-- Add the parameters for the stored procedure here
@PRODUCT_SKU nvarchar(15) = Null

AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;

IF OBJECT_ID('tempdb..##RelPro', 'U') IS NOT NULL
BEGIN
    DROP TABLE ##RelPro
END

Create Table ##RelPro
(
    RowID int identity(1,1),
    ID int,
    Item_Name nvarchar(max),
    SKU nvarchar(max),
    Vendor nvarchar(max),
    Product_Img_180 nvarchar(max),
    rpGroup int,
    Assoc_Item_1 nvarchar(max),
    Assoc_Item_2 nvarchar(max),
    Assoc_Item_3 nvarchar(max),
    Assoc_Item_4 nvarchar(max),
    Assoc_Item_5 nvarchar(max),
    Assoc_Item_6 nvarchar(max),
    Assoc_Item_7 nvarchar(max),
    Assoc_Item_8 nvarchar(max),
    Assoc_Item_9 nvarchar(max),
    Assoc_Item_10 nvarchar(max)
);

Begin
    Insert ##RelPro(ID, Item_Name, SKU, Vendor, Product_Img_180, rpGroup)

    Select distinct zp.ProductID, zp.Name, zp.SKU,
        (Select m.Name From ZNodeManufacturer m(nolock) Where m.ManufacturerID = zp.ManufacturerID),
        'http://s0001.server.com/is/sw11/DG/' + 
        (Select m.Custom1 From ZNodeManufacturer m(nolock) Where m.ManufacturerID = zp.ManufacturerID) +
        '_' + zp.SKU + '_3?$SC_3243$', ep.RoomID
    From Product zp(nolock) Inner Join RF_ExtendedProduct ep(nolock) On ep.ProductID = zp.ProductID
    Where zp.ActiveInd = 1 And SUBSTRING(zp.SKU, 1, 2) <> 'GC' AND zp.Name <> 'PLATINUM' AND zp.SKU = (Case When @PRODUCT_SKU Is Not Null Then @PRODUCT_SKU Else zp.SKU End)
End

declare @curr_row int = 0,
        @tot_rows int= 0,
        @sku nvarchar(15) = null;

IF OBJECT_ID('tempdb..##TSku', 'U') IS NOT NULL
BEGIN
    DROP TABLE ##TSku
END
Create Table ##TSku (tid int identity(1,1), relsku nvarchar(15));

Select @curr_row = (Select MIN(RowId) From ##RelPro);
Select @tot_rows = (Select MAX(RowId) From ##RelPro);

while @curr_row <= @tot_rows
Begin
    select @sku = SKU from ##RelPro where RowID = @curr_row;

    truncate table ##TSku;

    Insert ##TSku(relsku)
    Select distinct top(10) tzp.SKU From Product tzp(nolock) INNER JOIN 
    [INTRANET].raf_FocusAssociatedItem assoc(nolock) ON assoc.associatedItemID = tzp.SKU
    Where (assoc.isActive=1) And (tzp.ActiveInd = 1) AND (assoc.productID = @sku)

    declare @curr_row1 int = (Select Min(tid) From ##TSku),
            @tot_rows1 int = (Select Max(tid) From ##TSku);

    If(@tot_rows1 <> 0)
    Begin
        While @curr_row1 <= @tot_rows1
        Begin
            declare @col_name nvarchar(15) = null,
                    @sqlstat nvarchar(500) = null;
            set @col_name =  'Assoc_Item_' + Convert(nvarchar(2), @curr_row1);
            set @sqlstat = 'update ##RelPro set ' + @col_name + ' = (Select relsku From ##TSku Where tid = ' + Convert(nvarchar(2), @curr_row1) + ') Where RowID = ' + Convert(nvarchar(2), @curr_row);
            Exec(@sqlstat);
            set @curr_row1 = @curr_row1 + 1;
        End
    End
    set @curr_row = @curr_row + 1;
End

Select * From ##RelPro;

END GO

Using to_char:

select to_char(sysdate, 'YYYY') from dual;

In your example you can use something like:

BETWEEN trunc(sysdate, 'YEAR') 
    AND add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60;

The comparison values are exactly what you request:

select trunc(sysdate, 'YEAR') begin_year
     , add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60 last_second_year
from dual;

BEGIN_YEAR  LAST_SECOND_YEAR
----------- ----------------
01/01/2009  31/12/2009

You can copy the files into an appropriately named subdirectory directory of the data folder as long as it is the EXACT same version of mySQL and you have retained all of the associated files in that directory. If you don't have all the files, I'm pretty sure you're going to have issues.

Initially I was misled by this article which favours HttpClient.

Later I have been realized that HttpURLConnection is going to stay from this article

As per the Google blog:

Apache HTTP client has fewer bugs on Eclair and Froyo. It is the best choice for these releases. For Gingerbread , HttpURLConnection is the best choice. Its simple API and small size makes it great fit for Android.

Transparent compression and response caching reduce network use, improve speed and save battery. New applications should use HttpURLConnection; it is where we will be spending our energy going forward.

After reading this article and some other stack over flow questions, I am convinced that HttpURLConnection is going to stay for longer durations.

Some of the SE questions favouring HttpURLConnections:

On Android, make a POST request with URL Encoded Form data without using UrlEncodedFormEntity

HttpPost works in Java project, not in Android

You can use the NET START command and then check the ERRORLEVEL environment variable, e.g.

net start [your service]
if %errorlevel% == 2 echo Could not start service.
if %errorlevel% == 0 echo Service started successfully.
echo Errorlevel: %errorlevel%

Disclaimer: I've written this from the top of my head, but I think it'll work.

Step 1 : Login in Bitbucket

Step 2 : Select Your Repository in Repositories list.

Step 3 : Select branches in left hand side menu.

Step4 : Cursor point on branch click on three dots (...) Select Delete (See in Bellow Image)

To add to wflynny's answer above, you can find the available colormaps here

Example:

import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.jet)

or alternatively,

plt.scatter(x, y, c=t, cmap='jet')

You can extend the base android.app.Application class and add member variables like so:

public class MyApplication extends Application {

    private String someVariable;

    public String getSomeVariable() {
        return someVariable;
    }

    public void setSomeVariable(String someVariable) {
        this.someVariable = someVariable;
    }
}

In your android manifest you must declare the class implementing android.app.Application (add the android:name=".MyApplication" attribute to the existing application tag):

<application 
  android:name=".MyApplication" 
  android:icon="@drawable/icon" 
  android:label="@string/app_name">

Then in your activities you can get and set the variable like so:

// set
((MyApplication) this.getApplication()).setSomeVariable("foo");

// get
String s = ((MyApplication) this.getApplication()).getSomeVariable();

Readability can be improved by static factory methods:

Compare

public class Foo{
  public Foo(boolean withBar){
    //...
  }
}

//...

// What exactly does this mean?
Foo foo = new Foo(true);
// You have to lookup the documentation to be sure.
// Even if you remember that the boolean has something to do with a Bar
// you might not remember whether it specified withBar or withoutBar.

to

public class Foo{
  public static Foo createWithBar(){
    //...
  }

  public static Foo createWithoutBar(){
    //...
  }
}

// ...

// This is much easier to read!
Foo foo = Foo.createWithBar();

1. Check if you are referencing an assembly which in turn referencing an old version of unity. For example let's say you have an assembly called ServiceLocator.dll which needs an old version of Unity assembly, now when you reference the ServiceLocator you should provide it with the old version of Unity, and that makes the problem.

2. May be the output folder where all projects build their assemblies, has an old version of unity.

You can use FusLogVw to find out who is loading the old assemblies, just define a path for the log, and run your solution, then check (in FusLogvw) the first line where the Unity assembly is loaded, double click it and see the calling assembly, and here you go.

ok i had the same problem and i fix it like this by removing [] from [{"key":"value"}]:

1. in your php file make shure that you print like this

echo json_encode(array_shift($your_variable));

2. in your success function do this

 success: function (data) {
    var result = $.parseJSON(data);
      ('.yourclass').append(result['your_key1']);
      ('.yourclass').append(result['your_key2']);
       ..
    }

and also you can loop it if you want

Maybe this example listed here can help you out. Statement from the author

To give a more up-to-date approach.

package.json

  "scripts": {
    "eslint": "eslint index.js",
    "pretest": "npm install",
    "test": "npm run eslint",
    "preversion": "npm run test",
    "version": "",
    "postversion": "git push && git push --tags && npm publish"
  }

Then you run it:

npm version minor --force -m "Some message to commit"

Which will:

1. ... run tests ...

2. change your package.json to a next minor version (e.g: 1.8.1 to 1.9.0)

3. push your changes

4. create a new git tag release and

5. publish your npm package.

--force is to show who is the boss! Jokes aside see https://github.com/npm/npm/issues/8620

You're on the right track. The two constructors accept arguments, or you can specify them post-construction with ProcessBuilder#command(java.util.List) and ProcessBuilder#command(String...).

console.log has nothing to do with jQuery.

It logs a message to a debugging console, such as Firebug.

This should work:

SELECT YEAR(STR_TO_DATE(subdateshow, '%m/%d/%Y')) FROM table;

eg:

SELECT YEAR(STR_TO_DATE('01/17/2009', '%m/%d/%Y'));  /* shows "2009" */

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 28800
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 28800

At first, wait_timeout = 28800 which is the default value. To change the session value, you need to set the global variable because the session variable is read-only.

SET @@GLOBAL.wait_timeout=300

After you set the global variable, the session variable automatically grabs the value.

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 300
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 300

Next time when the server restarts, the session variables will be set to the default value i.e. 28800.

P.S. I m using MySQL 5.6.16

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

I needed something similar (left, center and right aligned items), but with ability to mark centered items as active. What worked for me was:

The code you basically provided, plus a call to connect should be sufficient. So yeah, it could be that just Google's not available but some other site you need to contact is on but how likely is that? Also, this code should only execute when you actually fail to access your external resource (in a catch block to try and figure out what the cause of the failure was) so I'd say that if both your external resource of interest and Google are not available chances are you have a net connectivity problem.

private static boolean netIsAvailable() {
    try {
        final URL url = new URL("http://www.google.com");
        final URLConnection conn = url.openConnection();
        conn.connect();
        conn.getInputStream().close();
        return true;
    } catch (MalformedURLException e) {
        throw new RuntimeException(e);
    } catch (IOException e) {
        return false;
    }
}

replace "150x150" with 720x720 and remove /vp/ from the link.it should work.

You can't use @android:style/TextAppearance as the parent for the whole app's theme; that's why koopaking3's solution seems quite broken.

To change default text colour everywhere in your app using a custom theme, try something like this. Works at least on Android 4.0+ (API level 14+).

res/values/themes.xml:

<resources>    
    <style name="MyAppTheme" parent="android:Theme.Holo.Light">
        <!-- Change default text colour from dark grey to black -->
        <item name="android:textColor">@android:color/black</item>
    </style>
</resources>

Manifest:

<application
    ...
    android:theme="@style/MyAppTheme">

Update

A shortcoming with the above is that also disabled Action Bar overflow menu items use the default colour, instead of being greyed out. (Of course, if you don't use disabled menu items anywhere in your app, this may not matter.)

As I learned by asking this question, a better way is to define the colour using a drawable:

<item name="android:textColor">@drawable/default_text_color</item>

...with res/drawable/default_text_color.xml specifying separate state_enabled="false" colour:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" android:color="@android:color/darker_gray"/>
    <item android:color="@android:color/black"/>
</selector>

From the man page (for bash ls):

Sort entries alphabetically if none of -cftuSUX nor --sort.

var assemblyPath = Assembly.GetExecutingAssembly().CodeBase;

You can use filter like this

angular.module('app').filter('trustAs', ['$sce', 
    function($sce) {
        return function (input, type) {
            if (typeof input === "string") {
                return $sce.trustAs(type || 'html', input);
            }
            console.log("trustAs filter. Error. input isn't a string");
            return "";
        };
    }
]);

usage

<div ng-bind-html="myData | trustAs"></div>

it can be used for other resource types, for example source link for iframes and other types declared here

You can also do this by service name.

First, try to find the service name of the respective pod which corresponds to multiple pods of the same service. kubectl get svc.

Next, run the following command to display logs from each container.

kubectl logs -f service/<service-name>

You can use ndiff in the difflib module to do this. It has all the information necessary to convert one string into another string.

A simple example:

import difflib

cases=[('afrykanerskojezyczny', 'afrykanerskojezycznym'),
       ('afrykanerskojezyczni', 'nieafrykanerskojezyczni'),
       ('afrykanerskojezycznym', 'afrykanerskojezyczny'),
       ('nieafrykanerskojezyczni', 'afrykanerskojezyczni'),
       ('nieafrynerskojezyczni', 'afrykanerskojzyczni'),
       ('abcdefg','xac')] 

for a,b in cases:     
    print('{} => {}'.format(a,b))  
    for i,s in enumerate(difflib.ndiff(a, b)):
        if s[0]==' ': continue
        elif s[0]=='-':
            print(u'Delete "{}" from position {}'.format(s[-1],i))
        elif s[0]=='+':
            print(u'Add "{}" to position {}'.format(s[-1],i))    
    print()      

prints:

afrykanerskojezyczny => afrykanerskojezycznym
Add "m" to position 20

afrykanerskojezyczni => nieafrykanerskojezyczni
Add "n" to position 0
Add "i" to position 1
Add "e" to position 2

afrykanerskojezycznym => afrykanerskojezyczny
Delete "m" from position 20

nieafrykanerskojezyczni => afrykanerskojezyczni
Delete "n" from position 0
Delete "i" from position 1
Delete "e" from position 2

nieafrynerskojezyczni => afrykanerskojzyczni
Delete "n" from position 0
Delete "i" from position 1

I had a similar issue in MVC (which lead me to this problem).

I am receiving a FORM as a string response from a WebClient.UploadValues() request, which I then have to submit - so I can't use a second WebClient or HttpWebRequest. This request returned the string.

using (WebClient client = new WebClient())
  {
    byte[] response = client.UploadValues(urlToCall, "POST", new NameValueCollection()
    {
        { "test", "value123" }
    });

    result = System.Text.Encoding.UTF8.GetString(response);
  }

My solution, which could be used to solve the OP, is to append a Javascript auto submit to the end of the code, and then using @Html.Raw() to render it on a Razor page.

result += "<script>self.document.forms[0].submit()</script>";
someModel.rawHTML = result;
return View(someModel);

Razor Code:

@model SomeModel

@{
    Layout = null;
}

@Html.Raw(@Model.rawHTML)

I hope this can help anyone who finds themselves in the same situation.

In theory, according to RFC 4329, application/javascript.

The reason it is supposed to be application is not anything to do with whether the type is readable or executable. It's because there are custom charset-determination mechanisms laid down by the language/type itself, rather than just the generic charset parameter. A subtype of text should be capable of being transcoded by a proxy to another charset, changing the charset parameter. This is not true of JavaScript because:

a. the RFC says user-agents should be doing BOM-sniffing on the script to determine type (I'm not sure if any browsers actually do this though);

b. browsers use other information—the including page's encoding and in some browsers the script charset attribute—to determine the charset. So any proxy that tried to transcode the resource would break its users. (Of course in reality no-one ever uses transcoding proxies anyway, but that was the intent.)

Therefore the exact bytes of the file must be preserved exactly, which makes it a binary application type and not technically character-based text.

For the same reason, application/xml is officially preferred over text/xml: XML has its own in-band charset signalling mechanisms. And everyone ignores application for XML, too.

text/javascript and text/xml may not be the official Right Thing, but there are what everyone uses today for compatibility reasons, and the reasons why they're not the right thing are practically speaking completely unimportant.

Actually you kind of can! Don't hassle with javascript... I was just stuck on the same thing for a website I'm making and if you increase the 'font-size' attribute in CSS for the tag then it automatically increases the height as well. Petty but it's something that bothers me a lot ha ha

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

There is U+1F50D LEFT-POINTING MAGNIFYING GLASS () and U+1F50E RIGHT-POINTING MAGNIFYING GLASS ().

You should use (in HTML) 🔍 or 🔎

They are, however not supported by many fonts (fileformat.info only lists a few fonts as supporting the Codepoint with a proper glyph).

Also note that they are outside of the BMP, so some Unicode-capable software might have problems rendering them, even if they have fonts that support them.

Generally Unicode Glyphs can be searched using a site such as fileformat.info. This searches "only" in the names and properties of the Unicode glyphs, but they usually contain enough metadata to allow for good search results (for this answer I searched for "glass" and browsed the resulting list, for example)

In addition to all the other answers you received, I want to explain the unknown option -- o error: Your command was

$ adb shell 'su -c  mount -o rw,remount /system'

which calls su through adb. You properly quoted the whole su command in order to pass it as one argument to adb shell. However, su -c <cmd> also needs you to quote the command with arguments it shall pass to the shell's -c option. (YMMV depending on su variants.) Therefore, you might want to try

$ adb shell 'su -c "mount -o rw,remount /system"'

(and potentially add the actual device listed in the output of mount | grep system before the /system arg – see the other answers.)

One interesting thing is we can view the tables horizontally, without folding. we can use PAGER environment variable. psql makes use of it. you can set

export PAGER='/usr/bin/less -S'

or just less -S if its already availble in command line, if not with the proper location. -S to view unfolded lines. you can pass in any custom viewer or other options with it.

I've written more in Psql Horizontal Display

As of Spring 5.1 you can use HttpHeaders.setBasicAuth

Create Basic Authorization header:

String username = "willie";
String password = ":p@ssword";
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth(username, password);
...other headers goes here...

Pass the headers to the RestTemplate:

HttpEntity<String> request = new HttpEntity<String>(headers);
ResponseEntity<Account> response = restTemplate.exchange(url, HttpMethod.GET, request, Account.class);
Account account = response.getBody();

In my context, just developed a class abstraction. When my application is launched, i check if localStorage is working by calling getStorage(). This function also return :

• either localStorage if localStorage is working
• or an implementation of a custom class LocalStorageAlternative

In my code i never call localStorage directly. I call cusStoglobal var, i had initialised by calling getStorage().

This way, it works with private browsing or specific Safari versions

function getStorage() {

    var storageImpl;

     try { 
        localStorage.setItem("storage", ""); 
        localStorage.removeItem("storage");
        storageImpl = localStorage;
     }
     catch (err) { 
         storageImpl = new LocalStorageAlternative();
     }

    return storageImpl;

}

function LocalStorageAlternative() {

    var structureLocalStorage = {};

    this.setItem = function (key, value) {
        structureLocalStorage[key] = value;
    }

    this.getItem = function (key) {
        if(typeof structureLocalStorage[key] != 'undefined' ) {
            return structureLocalStorage[key];
        }
        else {
            return null;
        }
    }

    this.removeItem = function (key) {
        structureLocalStorage[key] = undefined;
    }
}

cusSto = getStorage();

there are 2 solutions:

visit this jsfiddle

in your css you can add this:
     .input-disabled{background-color:#EBEBE4;border:1px solid #ABADB3;padding:2px 1px;}

in your js do something like this:
     $('#test').attr('readonly', true);
     $('#test').addClass('input-disabled');

Hope this help.

Another way is using hidden input field as mentioned by some of the comments. However bear in mind that, in the backend code, you need to make sure you validate this newly hidden input at correct scenario. Hence I'm not recommend this way as it will create more bugs if its not handle properly.

Ok guys I found the reason for my encoding issue.

The fault was in my build process. I didn't tell Maven in my pom.xml file to build the project with the UTF-8 encoding. Therefor Maven just took the default encoding from my system which is MacRoman and build it with the MacRoman encoding.

Luckily Maven is warning you about this when building your project (BUT there is a good chance that the warning disappears to fast from your screen because of all the other messages).

Here is the property you need to set in the pom.xml file:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    ...
</properties>

Thank you guys for all your help. Without you guys I wouldn't be able to figure this out!

When dealing with the HTML DOM (ie. this), the array selector [0] must be used to retrieve the jQuery element from the Javascript array.

You can use this datepicker functionality in anywhere just need to call on Master.aspx or Layout page

1. Include jQuery and jQuery UI libraries (I'm still using an old one)

   src="js/jquery-1.7.2.js"
   src="js/jquery-ui-1.7.2.js"
   

then add this script and this is working on all platforms.

 <script>
jQuery(function ($) { // wait until the DOM is ready
            $(".editorDate").datepicker({ dateFormat: 'yy-mm-dd' });
        });`
 </script>

you can add this "editorDate" on multiple pages.

@Html.TextBoxFor(model => model.FromDate, "{0:yyyy-MM-dd}", htmlAttributes: new { @class = "form-control editorDate"})

If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.

As one day is 1, one minute would be 1 / 1440 (there's 1440 minutes in a day).

So 30 minutes is 30 / 1440 = 0.02083333.

Final code:

$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });

I've added path: '/' so that you don't forget that the cookie is set on the current path. If you're on /my-directory/ the cookie is only set for this very directory.

Lapack is a Linear Algebra package which is used by R (actually it's used everywhere) underneath solve(), dgesv spits this kind of error when the matrix you passed as a parameter is singular.

As an addendum: dgesv performs LU decomposition, which, when using your matrix, forces a division by 0, since this is ill-defined, it throws this error. This only happens when matrix is singular or when it's singular on your machine (due to approximation you can have a really small number be considered 0)

I'd suggest you check its determinant if the matrix you're using contains mostly integers and is not big. If it's big, then take a look at this link.

So you want to create a list of lists... We need to start with an empty list

list_of_lists = []

next, we read the file content, line by line

with open('data') as f:
    for line in f:
        inner_list = [elt.strip() for elt in line.split(',')]
        # in alternative, if you need to use the file content as numbers
        # inner_list = [int(elt.strip()) for elt in line.split(',')]
        list_of_lists.append(inner_list)

A common use case is that of columnar data, but our units of storage are the rows of the file, that we have read one by one, so you may want to transpose your list of lists. This can be done with the following idiom

by_cols = zip(*list_of_lists)

Another common use is to give a name to each column

col_names = ('apples sold', 'pears sold', 'apples revenue', 'pears revenue')
by_names = {}
for i, col_name in enumerate(col_names):
    by_names[col_name] = by_cols[i]

so that you can operate on homogeneous data items

 mean_apple_prices = [money/fruits for money, fruits in
                     zip(by_names['apples revenue'], by_names['apples_sold'])]

Most of what I've written can be speeded up using the csv module, from the standard library. Another third party module is pandas, that lets you automate most aspects of a typical data analysis (but has a number of dependencies).

Update While in Python 2 zip(*list_of_lists) returns a different (transposed) list of lists, in Python 3 the situation has changed and zip(*list_of_lists) returns a zip object that is not subscriptable.

If you need indexed access you can use

by_cols = list(zip(*list_of_lists))

that gives you a list of lists in both versions of Python.

On the other hand, if you don't need indexed access and what you want is just to build a dictionary indexed by column names, a zip object is just fine...

file = open('some_data.csv')
names = get_names(next(file))
columns = zip(*((x.strip() for x in line.split(',')) for line in file)))
d = {}
for name, column in zip(names, columns): d[name] = column

At least on the current maven version you need to add the switch -DreResolve=false if you intend to remove the dependencies from your local repo without re-downloading them.

mvn dependency:purge-local-repository -DreResolve=false

removes the dependencies without downloading them again.

contentType option to false is used for multipart/form-data forms that pass files.

When one sets the contentType option to false, it forces jQuery not to add a Content-Type header, otherwise, the boundary string will be missing from it. Also, when submitting files via multipart/form-data, one must leave the processData flag set to false, otherwise, jQuery will try to convert your FormData into a string, which will fail.

Use jQuery's .serialize() method which creates a text string in standard URL-encoded notation.

You need to pass un-encoded data when using contentType: false.

Try using new FormData instead of .serialize():

  var formData = new FormData($(this)[0]);

See for yourself the difference of how your formData is passed to your php page by using console.log().

  var formData = new FormData($(this)[0]);
  console.log(formData);

  var formDataSerialized = $(this).serialize();
  console.log(formDataSerialized);

Cluster differs from Cloud and Grid in that a cluster is a group of computers connected by a local area network (LAN), whereas cloud and grid are more wide scale and can be geographically distributed. Another way to put it is to say that a cluster is tightly coupled, whereas a Grid or a cloud is loosely coupled. Also, clusters are made up of machines with similar hardware, whereas clouds and grids are made up of machines with possibly very different hardware configurations.

To know more about cloud computing, I recommend reading this paper: «Above the Clouds: A Berkeley View of Cloud Computing», Michael Armbrust, Armando Fox, Rean Griffith, Anthony D. Joseph, Randy H. Katz, Andrew Konwinski, Gunho Lee, David A. Patterson, Ariel Rabkin, Ion Stoica and Matei Zaharia. The following is an abstract from the above paper:

Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we call a Cloud. When a Cloud is made available in a pay-as-you-go manner to the general public, we call it a Public Cloud; the service being sold is Utility Computing. We use the term Private Cloud to refer to internal datacenters of a business or other organization, not made available to the general public. Thus, Cloud Computing is the sum of SaaS and Utility Computing, but does not include Private Clouds. People can be users or providers of SaaS, or users or providers of Utility Computing.

The difference between a cloud and a grid can be expressed as below:

1. Resource distribution: Cloud computing is a centralized model whereas grid computing is a decentralized model where the computation could occur over many administrative domains.

2. Ownership: A grid is a collection of computers which is owned by multiple parties in multiple locations and connected together so that users can share the combined power of resources. Whereas a cloud is a collection of computers usually owned by a single party.

Examples of Clouds: Amazon Web Services (AWS), Google App Engine.

Examples of Grids: FutureGrid.

Examples of cloud computing services: Dropbox, Gmail, Facebook, Youtube, RapidShare.

Is just casting the value returned by time()

#include <stdio.h>
#include <time.h>

int main(void) {
    printf("Timestamp: %d\n",(int)time(NULL));
    return 0;
}

what you want?

$ gcc -Wall -Wextra -pedantic -std=c99 tstamp.c && ./a.out
Timestamp: 1343846167

To get microseconds since the epoch, from C11 on, the portable way is to use

int timespec_get(struct timespec *ts, int base)

Unfortunately, C11 is not yet available everywhere, so as of now, the closest to portable is using one of the POSIX functions clock_gettime or gettimeofday (marked obsolete in POSIX.1-2008, which recommends clock_gettime).

The code for both functions is nearly identical:

#include <stdio.h>
#include <time.h>
#include <stdint.h>
#include <inttypes.h>

int main(void) {

    struct timespec tms;

    /* The C11 way */
    /* if (! timespec_get(&tms, TIME_UTC)) { */

    /* POSIX.1-2008 way */
    if (clock_gettime(CLOCK_REALTIME,&tms)) {
        return -1;
    }
    /* seconds, multiplied with 1 million */
    int64_t micros = tms.tv_sec * 1000000;
    /* Add full microseconds */
    micros += tms.tv_nsec/1000;
    /* round up if necessary */
    if (tms.tv_nsec % 1000 >= 500) {
        ++micros;
    }
    printf("Microseconds: %"PRId64"\n",micros);
    return 0;
}

I'll add my solution here. We can use floor when values are above 0 and ceil when they are less than zero:

function truncateToInt(x)
{
    if(x > 0)
    {
         return Math.floor(x);
    }
    else
    {
         return Math.ceil(x);
    }
 }

Then:

y = truncateToInt(2.9999); // results in 2
y = truncateToInt(-3.118); //results in -3

Notice: This answer was written when Math.trunc(x) was fairly new and not supported by a lot of browsers. Today, modern browsers support Math.trunc(x).

Same as matt said. The "SQL Server(SQLEXPRESS)" was stopped. Enabled it by opening Control Panel > Administrative Tools > Services, right-clicking on the "SQL Server(SQLEXPRESS)" service and selecting "Start" from the available options. Could connect fine after that.

I found this question as I had a similar problem. While data-backdrop does "solve" the issue; I found another problem in my markup.

I had the button which launched this modal and the modal dialog itself was in the footer. The problem is that the footer was defined as navbar_fixed_bottom, and that contained position:fixed.

After I moved the dialog outside of the fixed section, everything worked as expected.

I'll try to answer all your questions by addressing the larger question: How can I sync data between a webserver and an android app?

Syncing data between your webserver and an android app requires a couple of different components on your android device.

Persistent Storage:

This is how your phone actually stores the data it receives from the webserver. One possible method for accomplishing this is writing your own custom ContentProvider backed by a Sqlite database. A decent tutorial for a content provider can be found here: http://thinkandroid.wordpress.com/2010/01/13/writing-your-own-contentprovider/

A ContentProvider defines a consistent interface to interact with your stored data. It could also allow other applications to interact with your data if you wanted. Behind your ContentProvider could be a Sqlite database, a Cache, or any arbitrary storage mechanism.

While I would certainly recommend using a ContentProvider with a Sqlite database you could use any java based storage mechanism you wanted.

Data Interchange Format:

This is the format you use to send the data between your webserver and your android app. The two most popular formats these days are XML and JSON. When choosing your format, you should think about what sort of serialization libraries are available. I know off-hand that there's a fantastic library for json serialization called gson: https://github.com/google/gson, although I'm sure similar libraries exist for XML.

Synchronization Service

You'll want some sort of asynchronous task which can get new data from your server and refresh the mobile content to reflect the content of the server. You'll also want to notify the server whenever you make local changes to content and want to reflect those changes. Android provides the SyncAdapter pattern as a way to easily solve this pattern. You'll need to register user accounts, and then Android will perform lots of magic for you, and allow you to automatically sync. Here's a good tutorial: http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1/

As for how you identify if the records are the same, typically you'll create items with a unique id which you store both on the android device and the server. You can use that to make sure you're referring to the same reference. Furthermore, you can store column attributes like "updated_at" to make sure that you're always getting the freshest data, or you don't accidentally write over newly written data.

 string htmlCode = "<p>This is a p tag</p>";

//use single thread to generate the pdf from above html code
Thread thread = new Thread(() =>
{ pdf.LoadFromHTML(htmlCode, false, setting, htmlLayoutFormat); });
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
thread.Join();

// Save the file to PDF and preview it.
pdf.SaveToFile("output.pdf");
System.Diagnostics.Process.Start("output.pdf");

Something in the lines of

myString.split("\\s+");

This groups all white spaces as a delimiter.

So if I have the string:

"Hello[space character][tab character]World"

This should yield the strings "Hello" and "World" and omit the empty space between the [space] and the [tab].

As VonC pointed out, the backslash should be escaped, because Java would first try to escape the string to a special character, and send that to be parsed. What you want, is the literal "\s", which means, you need to pass "\\s". It can get a bit confusing.

The \\s is equivalent to [ \\t\\n\\x0B\\f\\r].

You can use below method :

Route::getCurrentRoute()->getPath();

In Laravel version > 6.0, You can use below methods:

$route = Route::current();

$name = Route::currentRouteName();

$action = Route::currentRouteAction();

ssh-keygen -i -m PKCS8 -f public-key.pem

In this case it is better to use basename instead of awk:

 $ basename /home/parent/child1/child2/filename
 filename

I Had similar issue. Every project has his own gradle folder, check if in your project root there's another gradle folder:

/my_projects_root_folder/project/gradle
/my_projects_root_folder/gradle

If so, in every folder you'll find /gradle/wrapper/gradle-wrapper.properties.

Check if in /my_projects_root_folder/gradle/gradle-wrapper.properties gradle version at least match /my_projects_root_folder/ project/ gradle/ gradle-wrapper.properties gradle version

Or just delete/rename your /my_projects_root_folder/gradle and restart android studio and let Gradle sync work and download required gradle.

no your ans is Wrong

Selection of Al and Ah is from AX not from EAX

e.g

EAX=0000 0000 0000 0000 0000 0000 0000 0111

So if we call AX it should return

0000 0000 0000 0111

if we call AH it should return

0000 0000

and when we call AL it should return

0000 0111

Example number 2

EAX: 22 33 55 77
AX: 55 77
AH: 55    
AL: 77

example 3

EAX: 1111 0000 0000 0000 0000 0000 0000 0111    
AX= 0000 0000 0000 0111
AH= 0000 0000
AL= 0000 0111  

If you installed the command line tools separately, delete them using:

sudo rm -rf /Library/Developer/CommandLineTools

You can use like 'A%' expression, but if you want this query to run fast for large tables I'd recommend you to put number of first button into separate field with tiny int type.

If you want to avoid the dependency on System.Web that is required to use HttpUtility.ParseQueryString, you could use the Uri extension method ParseQueryString found in System.Net.Http.

Make sure to add a reference (if you haven't already) to System.Net.Http in your project.

Note that you have to convert the response body to a valid Uri so that ParseQueryString (in System.Net.Http)works.

string body = "value1=randomvalue1&value2=randomValue2";

// "http://localhost/query?" is added to the string "body" in order to create a valid Uri.
string urlBody = "http://localhost/query?" + body;
NameValueCollection coll = new Uri(urlBody).ParseQueryString();

Taken from https://superuser.com/questions/238944/how-to-force-excel-to-open-csv-files-with-data-arranged-in-columns

The behavior of Excel when opening CSV files heavily depends on your local settings and the selected list separator under Region and language » Formats » Advanced. By default Excel will assume every CSV was saved with that separator. Which is true as long as the CSV doesn't come from another country!

If your customers are in other countries, they may see other results then you think.

For example, here you see that a German Excel will use semicolon instead of comma like in the U.S.

Easy way:

Open the file bootstrap-datepicker.js

Go to line 1399 and find format: 'mm/dd/yyyy'.

Now you can change the date format here.

1. Find the attribute card_view:cardUseCompatPadding="true" in cards_layout.xml and delete it. Start app and you will find there is no margin between each cardview item.

2. Add margin attributes you like. Ex:

   android:layout_marginTop="5dp"
   android:layout_marginBottom="5dp" 
   

Try this:

item.shipping!==undefined

Here a solution, working if you want to print output while process is running or not.

I added the current working directory also, it was useful to me more than once.

Hoping the solution will help someone :).

import subprocess

def run_command(cmd_and_args, print_constantly=False, cwd=None):
"""Runs a system command.

:param cmd_and_args: the command to run with or without a Pipe (|).
:param print_constantly: If True then the output is logged in continuous until the command ended.
:param cwd: the current working directory (the directory from which you will like to execute the command)
:return: - a tuple containing the return code, the stdout and the stderr of the command
"""
output = []

process = subprocess.Popen(cmd_and_args, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd=cwd)

while True:
    next_line = process.stdout.readline()
    if next_line:
        output.append(str(next_line))
        if print_constantly:
            print(next_line)
    elif not process.poll():
        break

error = process.communicate()[1]

return process.returncode, '\n'.join(output), error

Just for the sake of completeness, I would suggest using the InnerHTML way as well - even though I would not call it the best way...

document.getElementById("image-holder").innerHTML = "<img src='image.png' alt='The Image' />";

By the way, innerHTML is not that bad

Using the ampersand (&) will run the command in a child process (child to the current bash session). However, when you exit the session, all child processes will be killed.

using nohup + ampersand (&) will do the same thing, except that when the session ends, the parent of the child process will be changed to "1" which is the "init" process, thus preserving the child from being killed.

It's simple:

array = []

will set array to be an empty list. (They're called lists in Python, by the way, not arrays)

If that doesn't work for you, edit your question to include a code sample that demonstrates your problem.

If your VARCHAR column contains empty strings (which are not the same as NULL for PostgreSQL as you might recall) you will have to use something in the line of the following to set a default:

ALTER TABLE presales ALTER COLUMN code TYPE NUMERIC(10,0)
            USING COALESCE(NULLIF(code, '')::NUMERIC, 0);

(found with the help of this answer)

So my solution to my own problem: After playing around with redis-cli a bit longer I found out that DEBUG OBJECT <key> reveals something like the serializedlength of key, which was in fact something I was looking for...

For a whole database you need to aggregate all values for KEYS * which shouldn't be too difficult with a scripting language of your choice...

The bad thing is that redis.io doesn't really have a lot of information about DEBUG OBJECT.

In my case I was missing 'www.' from the url I was pushing. It must be exact match, if you're working on www.test.com, you must push to www.test.com and not test.com

You can just use the following syntax and the object will be fully shown in the console:

console.log('object evt: %O', object);

I use Chrome browser don't know if this is adaptable for other browsers.
