I use following extension methods for epoch conversion

public static int GetEpochSeconds(this DateTime date)
    {
        TimeSpan t = DateTime.UtcNow - new DateTime(1970, 1, 1);
        return (int)t.TotalSeconds;
    }

public static DateTime FromEpochSeconds(this DateTime date, long EpochSeconds)
    {
        var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
        return epoch.AddSeconds(EpochSeconds);

    }

It is possible to use apache commons (commons-lang3) and its DurationFormatUtils class.

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.1</version>
</dependency>

For example:

String formattedDuration = DurationFormatUtils.formatDurationHMS(12313152);
// formattedDuration value is "3:25:13.152"
String otherFormattedDuration = DurationFormatUtils.formatDuration(12313152, DurationFormatUtils.ISO_EXTENDED_FORMAT_PATTERN);
// otherFormattedDuration value is "P0000Y0M0DT3H25M13.152S"

Hope it can help ...

public static class UnixTime
    {
        private static readonly DateTime Epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0);

        public static DateTime UnixTimeToDateTime(double unixTimeStamp)
        {
            return Epoch.AddSeconds(unixTimeStamp).ToUniversalTime();
        }
    }

you can call UnixTime.UnixTimeToDateTime(double datetime))

The simplest solution I've found to this, is:

var timestamp = Date.now(), // returns milliseconds since epoch time
    normalisedTime = new Date(timestamp);

Notice this doesn't have the * 1000 at the end of new Date(timestamp) statement as this (for me anyway!) always seems to give out the wrong date, ie instead of giving the year 2019 it gives the year as 51015, so just bear that in mind.

echo `date +%s`/86400 | bc

History.

The earliest versions of Unix time had a 32-bit integer incrementing at a rate of 60 Hz, which was the rate of the system clock on the hardware of the early Unix systems. The value 60 Hz still appears in some software interfaces as a result. The epoch also differed from the current value. The first edition Unix Programmer's Manual dated November 3, 1971 defines the Unix time as "the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second".

Here is a function I made based on the answer above

def getDateToEpoch(myDateTime):
    res = (datetime.datetime(myDateTime.year,myDateTime.month,myDateTime.day,myDateTime.hour,myDateTime.minute,myDateTime.second) - datetime.datetime(1970,1,1)).total_seconds()
    return res

You can wrap the returned value like this : str(int(res)) To return it without a decimal value to be used as string or just int (without the str)

It’s about time someone provides the modern answer to this question. In 2012 when the question was asked, the answers also posted back then were good answers. Why the answers posted in 2016 also use the then long outdated classes SimpleDateFormat and Date is a bit more of a mystery to me. java.time, the modern Java date and time API also known as JSR-310, is so much nicer to work with. You can use it on Android through the ThreeTenABP, see this question: How to use ThreeTenABP in Android Project.

For most purposes I recommend using the milliseconds since the epoch at the start of the day in UTC. To obtain these:

    DateTimeFormatter dateFormatter
            = DateTimeFormatter.ofPattern("d-MMMM-uuuu", Locale.ENGLISH);
    String stringDate = "12-December-2012";
    long millisecondsSinceEpoch = LocalDate.parse(stringDate, dateFormatter)
            .atStartOfDay(ZoneOffset.UTC)
            .toInstant()
            .toEpochMilli();
    System.out.println(millisecondsSinceEpoch);

This prints:

1355270400000

If you require the time at start of day in some specific time zone, specify that time zone instead of UTC, for example:

            .atStartOfDay(ZoneId.of("Asia/Karachi"))

As expected this gives a slightly different result:

1355252400000

Another point to note, remember to supply a locale to your DateTimeFormatter. I took December to be English, there are other languages where that month is called the same, so please choose the proper locale yourself. If you didn’t provide a locale, the formatter would use the JVM’s locale setting, which may work in many cases, and then unexpectedly fail one day when you run your app on a device with a different locale setting.

For those that want it ISO 8601 compliant, since the other solutions do not have the T separator nor the time offset (except Meistro's answer):

from datetime import datetime, timezone
result = datetime.fromtimestamp(1463288494, timezone.utc).isoformat('T', 'microseconds')
print(result) # 2016-05-15T05:01:34.000000+00:00

Note, I use fromtimestamp because if I used utcfromtimestamp I would need to chain on .astimezone(...) anyway to get the offset.

If you don't want to go all the way to microseconds you can choose a different unit with the isoformat() method.

For 32-bit systems:

fprintf(stdout, "%u\n", (unsigned)time(NULL)); 

For 64-bit systems:

fprintf(stdout, "%lu\n", (unsigned long)time(NULL)); 

those are miliseconds, just divide them by 1000, since gmtime expects seconds ...

time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(1236472051807/1000.0))

  String dateTime="15-3-2019 09:50 AM" //time should be two digit like 08,09,10 
   DateTimeFormatter dtf  = DateTimeFormatter.ofPattern("dd-MM-yyyy hh:mm a");
        LocalDateTime zdt  = LocalDateTime.parse(dateTime,dtf);
        LocalDateTime now = LocalDateTime.now();
        ZoneId zone = ZoneId.of("Asia/Kolkata");
        ZoneOffset zoneOffSet = zone.getRules().getOffset(now);
        long a= zdt.toInstant(zoneOffSet).toEpochMilli();
        Log.d("time","---"+a);

you can get zone id form this a link!

In Python 3.7

Return a datetime corresponding to a date_string in one of the formats emitted by date.isoformat() and datetime.isoformat(). Specifically, this function supports strings in the format(s) YYYY-MM-DD[*HH[:MM[:SS[.fff[fff]]]][+HH:MM[:SS[.ffffff]]]], where * can match any single character.

Here's a human-readable time stamp that may be used in a file name, just in case someone needs the same thing that I needed:

package com.example.xyz;

import android.text.format.Time;

/**
 * Clock utility.
 */
public class Clock {

    /**
     * Get current time in human-readable form.
     * @return current time as a string.
     */
    public static String getNow() {
        Time now = new Time();
        now.setToNow();
        String sTime = now.format("%Y_%m_%d %T");
        return sTime;
    }
    /**
     * Get current time in human-readable form without spaces and special characters.
     * The returned value may be used to compose a file name.
     * @return current time as a string.
     */
    public static String getTimeStamp() {
        Time now = new Time();
        now.setToNow();
        String sTime = now.format("%Y_%m_%d_%H_%M_%S");
        return sTime;
    }

}

Convert from human readable date to epoch:

long epoch = new java.text.SimpleDateFormat("MM/dd/yyyyHH:mm:ss").parse("01/01/1970 01:00:00").getTime() / 1000;

Convert from epoch to human readable date:

String date = new java.text.SimpleDateFormat("MM/dd/yyyyHH:mm:ss").format(new java.util.Date (epoch*1000));

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

The "wipe user data" option finally solved my problem. just wipe user data every time you start the emulator. This always works for me! I use windows 8 x64 , eclipse

public static Date convertTimestampToDate(Timestamp timestamp)  {
        Instant ins=timestamp.toLocalDateTime().atZone(ZoneId.systemDefault()).toInstant();
        return  Date.from(ins);
}

The purpose of .iteritems() was to use less memory space by yielding one result at a time while looping. I am not sure why Python 3 version does not support iteritems()though it's been proved to be efficient than .items()

If you want to include a code that supports both the PY version 2 and 3,

try:
    iteritems
except NameError:
    iteritems = items

This can help if you deploy your project in some other system and you aren't sure about the PY version.

Use

scanf("%d", &array[0]);

and use == for comparision instead of =

My issue is :

return __import__('MySQLdb')
ImportError: No module named MySQLdb

and my resolution :

pip install MySQL-python
yum install mysql-devel.x86_64

at the very beginning, i just installed MySQL-python, but the issue still existed. So i think if this issue happened, you should also take mysql-devel into consideration. Hope this helps.

I can imagine following advantages of having a class method defined as static one:

• you can call the method just using class name, no need to instantiate it.

remaining advantages are probably marginal if present at all:

• might run a bit faster
• save a bit of memory

The main reason is probably that a C++ string is a struct that includes a current-length value, not just the address of a sequence of chars terminated by a 0 byte. Printf and its relatives expect to find such a sequence, not a struct, and therefore get confused by C++ strings.

Speaking for myself, I believe that printf has a place that can't easily be filled by C++ syntactic features, just as table structures in html have a place that can't easily be filled by divs. As Dykstra wrote later about the goto, he didn't intend to start a religion and was really only arguing against using it as a kludge to make up for poorly-designed code.

It would be quite nice if the GNU project would add the printf family to their g++ extensions.

newString = yourString.Substring(0, yourString.length -1);

Simply using re.sub might also work instead of str.maketrans. And this would also work in python 2.x

>>> print(re.sub(r'(\-|\]|\^|\$|\*|\.|\\)',lambda m:{'-':'\-',']':'\]','\\':'\\\\','^':'\^','$':'\$','*':'\*','.':'\.'}[m.group()],"^stack.*/overflo\w$arr=1"))
\^stack\.\*/overflo\\w\$arr=1

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Found this gem from our friends over at SitePoint. https://www.sitepoint.com/url-parameters-jquery/.

Using PURE jQuery. I just used this and it worked. Tweaked it a bit for example sake.

//URL is http://www.example.com/mypage?ref=registration&[email protected]

$.urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)')
                      .exec(window.location.search);

    return (results !== null) ? results[1] || 0 : false;
}

console.log($.urlParam('ref')); //registration
console.log($.urlParam('email')); //[email protected]

Use as you will.

Maybe it help someone somewhere, in my case (which was a private repo of git), host was suspended, so the issue was with my GitHub server and the administrator resolved it.

public static void main(String[] args) throws FileNotFoundException, IOException {
        File file = new File("java.pdf");

        FileInputStream fis = new FileInputStream(file);
        //System.out.println(file.exists() + "!!");
        //InputStream in = resource.openStream();
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        byte[] buf = new byte[1024];
        try {
            for (int readNum; (readNum = fis.read(buf)) != -1;) {
                bos.write(buf, 0, readNum); //no doubt here is 0
                //Writes len bytes from the specified byte array starting at offset off to this byte array output stream.

You can use the build job step from Jenkins Pipeline (Minimum Jenkins requirement: 2.130).

Here's the full API for the build step: https://jenkins.io/doc/pipeline/steps/pipeline-build-step/

How to use build:

• job: Name of a downstream job to build. May be another Pipeline job, but more commonly a freestyle or other project.
  • Use a simple name if the job is in the same folder as this upstream Pipeline job;
  • You can instead use relative paths like ../sister-folder/downstream
  • Or you can use absolute paths like /top-level-folder/nested-folder/downstream

Trigger another job using a branch as a param

At my company many of our branches include "/". You must replace any instances of "/" with "%2F" (as it appears in the URL of the job).

In this example we're using relative paths

    stage('Trigger Branch Build') {
        steps {
            script {
                    echo "Triggering job for branch ${env.BRANCH_NAME}"
                    BRANCH_TO_TAG=env.BRANCH_NAME.replace("/","%2F")
                    build job: "../my-relative-job/${BRANCH_TO_TAG}", wait: false
            }
        }
    }

Trigger another job using build number as a param

build job: 'your-job-name', 
    parameters: [
        string(name: 'passed_build_number_param', value: String.valueOf(BUILD_NUMBER)),
        string(name: 'complex_param', value: 'prefix-' + String.valueOf(BUILD_NUMBER))
    ]

Trigger many jobs in parallel

Source: https://jenkins.io/blog/2017/01/19/converting-conditional-to-pipeline/

More info on Parallel here: https://jenkins.io/doc/book/pipeline/syntax/#parallel

    stage ('Trigger Builds In Parallel') {
        steps {
            // Freestyle build trigger calls a list of jobs
            // Pipeline build() step only calls one job
            // To run all three jobs in parallel, we use "parallel" step
            // https://jenkins.io/doc/pipeline/examples/#jobs-in-parallel
            parallel (
                linux: {
                    build job: 'full-build-linux', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
                },
                mac: {
                    build job: 'full-build-mac', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
                },
                windows: {
                    build job: 'full-build-windows', parameters: [string(name: 'GIT_BRANCH_NAME', value: env.BRANCH_NAME)]
                },
                failFast: false)
        }
    }

Or alternatively:

    stage('Build A and B') {
            failFast true
            parallel {
                stage('Build A') {
                    steps {
                            build job: "/project/A/${env.BRANCH}", wait: true
                    }
                }
                stage('Build B') {
                    steps {
                            build job: "/project/B/${env.BRANCH}", wait: true
                    }
                }
            }
    }

If the two controller is nested in One controller.
Then you can simply call:

$scope.parentmethod();  

Angular will search for parentmethod function starting with current scope and up until it will reach the rootScope.

Try this may will help you.Go to "File" -> "Invalidate Caches...", and select "Invalidate and Restart" option to fix this.

The third row you expect (the one with Powerpoint) is filtered out by the Computer.ID = 1 condition (try running the query with the Computer.ID = 1 or Computer.ID is null it to see what happens).

However, dropping that condition would not make sense, because after all, we want the list for a given Computer.

The only solution I see is performing a UNION between your original query and a new query that retrieves the list of application that are not found on that Computer.

The query might look like this:

DECLARE @ComputerId int
SET @ComputerId = 1

-- your original query
SELECT Computer.ComputerName, Application.Name, Software.Version
    FROM Computer
    JOIN dbo.Software_Computer
        ON Computer.ID = Software_Computer.ComputerID
    JOIN dbo.Software
        ON Software_Computer.SoftwareID = Software.ID
    RIGHT JOIN dbo.Application
        ON Application.ID = Software.ApplicationID
    WHERE Computer.ID = @ComputerId

UNION

-- query that retrieves the applications not installed on the given computer
SELECT Computer.ComputerName, Application.Name, NULL as Version
FROM Computer, Application
WHERE Application.ID not in 
    (
        SELECT s.ApplicationId
        FROM Software_Computer sc
        LEFT JOIN Software s on s.ID = sc.SoftwareId
        WHERE sc.ComputerId = @ComputerId
    )
AND Computer.id = @ComputerId

The worst case of Euclid Algorithm is when the remainders are the biggest possible at each step, ie. for two consecutive terms of the Fibonacci sequence.

When n and m are the number of digits of a and b, assuming n >= m, the algorithm uses O(m) divisions.

Note that complexities are always given in terms of the sizes of inputs, in this case the number of digits.

In some cases you can use an Int32 type (or Int64) in case of the IntPtr. If you can, another useful class is BitConverter. For what you want you could use BitConverter.ToInt32 for example.

Maybe these examples will help illustrate what in does. It basically translate to Is this item in this other item?

listOfNums = [ 1, 2, 3, 4, 5, 6, 45, 'j' ]

>>> 3 in listOfNums:
>>> True

>>> 'j' in listOfNums:
>>> True

>>> 66 in listOfNums:
>>> False

If you look at this bug 224128, it appears that MergeSort is being used by Mozilla.

I prefer the first version to start a java application just because it has less pitfalls ("welcome to classpath hell"). The second one requires an executable jar file and the classpath for that application has to be defined inside the jar's manifest (all other classpath declaration will be silently ignored...). So with the second version you'd have to look into the jar, read the manifest and try to find out if the classpath entries are valid from where the jar is stored... That's avoidable.

I don't expect any performance advantages or disadvantages for either version. It's just telling the jvm which class to use for the main thread and where it can find the libraries.

Use this, it works fine.

I'd like to point out few more solutions to transposing columns and rows in SQL.

The first one is - using CURSOR. Although the general consensus in the professional community is to stay away from SQL Server Cursors, there are still instances whereby the use of cursors is recommended. Anyway, Cursors present us with another option to transpose rows into columns.

• Vertical expansion

  Similar to the PIVOT, the cursor has the dynamic capability to append more rows as your dataset expands to include more policy numbers.

• Horizontal expansion

  Unlike the PIVOT, the cursor excels in this area as it is able to expand to include newly added document, without altering the script.

• Performance breakdown

  The major limitation of transposing rows into columns using CURSOR is a disadvantage that is linked to using cursors in general – they come at significant performance cost. This is because the Cursor generates a separate query for each FETCH NEXT operation.

Another solution of transposing rows into columns is by using XML.

The XML solution to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation.

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

• Vertical expansion

  Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

• Horizontal expansion

  Unlike the PIVOT, newly added documents can be displayed without altering the script.

• Performance breakdown

  In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

Another way to do it is to create a dynamic javascript returned by a java controller like it is written here in the thymeleaf forum: http://forum.thymeleaf.org/Can-I-use-th-inline-for-a-separate-javascript-file-td4025766.html

One way to handle this is to create a dynamic javascript file with the URLs embedded in it. Here are the steps (if you are using Spring MVC)

@RequestMapping(path = {"/dynamic.js"}, method = RequestMethod.GET, produces = "application/javascript")
@ResponseStatus(value = HttpStatus.OK)
@ResponseBody
public String dynamicJS(HttpServletRequest request) {

        return "Your javascript code....";

}


  

Following up as of 2019-04-04, this seems to be able to be accomplished with the React Hooks' useState:

import React, { useState } from 'react'
import uniqueId from 'lodash/utility/uniqueId'

const Field = props => {
  const [ id ] = useState(uniqueId('myprefix-'))

  return (
    <div>
      <label htmlFor={id}>{props.label}</label>
      <input id={id} type="text"/>
    </div>
  )      
}

export default Field

As I understand it, you ignore the second array item in the array destructuring that would allow you to update id, and now you've got a value that won't be updated again for the life of the component.

The value of id will be myprefix-<n> where <n> is an incremental integer value returned from uniqueId. If that's not unique enough for you, consider making your own like

function gen4() {
  return Math.random().toString(16).slice(-4)
}

function simpleUniqueId(prefix) {
  return (prefix || '').concat([
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4(),
    gen4()
  ].join(''))
}

or check out the library I published with this here: https://github.com/rpearce/simple-uniqueid. There are also hundreds or thousands of other unique ID things out there, but lodash's uniqueId with a prefix should be enough to get the job done.

Update 2019-07-10

Thanks to @Huong Hk for pointing me to hooks lazy initial state, the sum of which is that you can pass a function to useState that will only be run on the initial mount.

// before
const [ id ] = useState(uniqueId('myprefix-'))

// after
const [ id ] = useState(() => uniqueId('myprefix-'))

employees.ToList().ForEach(
     emp=>
     {
          collection.AddRange(emp.Departments);
          emp.Departments.ToList().ForEach(u=>u.SomeProperty = null);
     });

It's been a significant percentage of our business migrating people from Heroku to AWS. There are advantages to both, but it's gets messy on Heroku after a while... once you need a certain level of complexity no longer easy to maintain with Heroku's limitations.

That said, there are increasingly options to have the ease of Heroku and the flexibility of AWS by being on AWS with great frameworks/tools.

Alternatively, you can also use a special function known as the linear-gradient() function to split browser screen into two equal halves. Check out the following code snippet:

body
{
  background-image:linear-gradient(90deg, lightblue 50%, skyblue 50%);
}

Here, linear-gradient() function accepts three arguments

1. 90deg for vertical division of screen.( Similarly, you can use 180deg for horizontal division of screen)
2. lightblue color is used to represent the left half of the screen.
3. skyblue color has been used to represent the right half of the split screen. Here, 50% has been used for equal division of the browser screen. You can use any other value if you don't want an equal division of the screen. Hope this helps. :) Happy Coding!

You are reading all rows into a list, then processing that list. Don't do that.

Process your rows as you produce them. If you need to filter the data first, use a generator function:

import csv

def getstuff(filename, criterion):
    with open(filename, "rb") as csvfile:
        datareader = csv.reader(csvfile)
        yield next(datareader)  # yield the header row
        count = 0
        for row in datareader:
            if row[3] == criterion:
                yield row
                count += 1
            elif count:
                # done when having read a consecutive series of rows 
                return

I also simplified your filter test; the logic is the same but more concise.

Because you are only matching a single sequence of rows matching the criterion, you could also use:

import csv
from itertools import dropwhile, takewhile

def getstuff(filename, criterion):
    with open(filename, "rb") as csvfile:
        datareader = csv.reader(csvfile)
        yield next(datareader)  # yield the header row
        # first row, plus any subsequent rows that match, then stop
        # reading altogether
        # Python 2: use `for row in takewhile(...): yield row` instead
        # instead of `yield from takewhile(...)`.
        yield from takewhile(
            lambda r: r[3] == criterion,
            dropwhile(lambda r: r[3] != criterion, datareader))
        return

You can now loop over getstuff() directly. Do the same in getdata():

def getdata(filename, criteria):
    for criterion in criteria:
        for row in getstuff(filename, criterion):
            yield row

Now loop directly over getdata() in your code:

for row in getdata(somefilename, sequence_of_criteria):
    # process row

You now only hold one row in memory, instead of your thousands of lines per criterion.

yield makes a function a generator function, which means it won't do any work until you start looping over it.

No there isn't. If you watch the http traffic and dump the page source you can see that there is an API below the covers, but it's not published nor available for 3rd party apps.

Check this link: https://developers.google.com/gsuite/products for updates.

However, there is an unofficial Python API under active development: https://github.com/kiwiz/gkeepapi

I may suggest NOT looping over each rows EACH time CellFormating is called, because it is called everytime A SINGLE ROW need to be refreshed.

Private Sub dgv_DisplayData_Vertical_CellFormatting(sender As Object, e As DataGridViewCellFormattingEventArgs) Handles dgv_DisplayData_Vertical.CellFormatting
        Try

            If dgv_DisplayData_Vertical.Rows(e.RowIndex).Cells("LevelID").Value.ToString() = "6" Then

                e.CellStyle.BackColor = Color.DimGray
            End If
            If dgv_DisplayData_Vertical.Rows(e.RowIndex).Cells("LevelID").Value.ToString() = "5" Then
                e.CellStyle.BackColor = Color.DarkSlateGray
            End If
            If dgv_DisplayData_Vertical.Rows(e.RowIndex).Cells("LevelID").Value.ToString() = "4" Then
                e.CellStyle.BackColor = Color.SlateGray
            End If
            If dgv_DisplayData_Vertical.Rows(e.RowIndex).Cells("LevelID").Value.ToString() = "3" Then
                e.CellStyle.BackColor = Color.LightGray
            End If
            If dgv_DisplayData_Vertical.Rows(e.RowIndex).Cells("LevelID").Value.ToString() = "0" Then
                e.CellStyle.BackColor = Color.White
            End If

        Catch ex As Exception

        End Try

    End Sub

The best way I've found is:

<script type="text/javascript">
    $(document).ready(function() {
        $.fancybox(
             $("#WRAPPER_FOR_hidden_div_with_content_to_show").html(), //fancybox works perfect with hidden divs
             {
                  //fancybox options
             }
        );
    });
</script>

This is due to IFS (Internal Field Separator) variable which contains newline.

$ cat xx1
1
2

$ A=`cat xx1`
$ echo $A
1 2

$ echo "|$IFS|"
|       
|

A workaround is to reset IFS to not contain the newline, temporarily:

$ IFSBAK=$IFS
$ IFS=" "
$ A=`cat xx1` # Can use $() as well
$ echo $A
1
2
$ IFS=$IFSBAK

To REVERT this horrible change for IFS:

IFS=$IFSBAK

install --record + xargs rm

sudo python setup.py install --record files.txt
xargs sudo rm -rf < files.txt

removes all files and but leaves empty directories behind.

That is not ideal, it should be enough to avoid package conflicts.

And then you can finish the job manually if you want by reading files.txt, or be braver and automate empty directory removal as well.

A safe helper would be:

python-setup-uninstall() (
  sudo rm -f files.txt
  sudo python setup.py install --record files.txt && \
  xargs rm -rf < files.txt
  sudo rm -f files.txt
)

Tested in Python 2.7.6, Ubuntu 14.04.

Say you have a branch master with the following commit history:

A -- B -- C -- D

Now, you create a branch test, work on it, and do 4 commits:

                 E -- F -- G -- H
                /
A -- B -- C -- D

master's head points to D, and test's head points to H.

The "Already up-to-date" message shows up when the HEAD of the branch you are merging into is a parent of the chain of commits of the branch you want to merge. That's the case, here: D is a parent of E.

There is nothing to merge from test to master, since nothing has changed on master since then. What you want to do here is literally to tell Git to have master's head to point to H, so master's branch has the following commits history:

A -- B -- C -- D -- E -- F -- G -- H

This is a job for Git command reset. You also want the working directory to reflect this change, so you'll do a hard reset:

git reset --hard H

1. Right-click an object in Chrome's console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.

2. Chrome also has a copy() method, so copy(temp1) in the console should copy that object to your clipboard.

Note on Recursive Objects: If you're trying to copy a recursive object, you will get [object Object]. The way out is to copy(JSON.stringify(temp1)) , the object will be fully copied to your clipboard as a valid JSON, so you'd be able to format it as you wish, using one of many resources.

HTML5 has a built-in combo box. You create a text input and a datalist. Then you add a list attribute to the input, with a value of the id of the datalist.

Update: As of March 2019 all major browsers (now including Safari 12.1 and iOS Safari 12.3) support datalist to the level needed for this functionality. See caniuse for detailed browser support.

It looks like this:

<input type="text" list="cars" />_x000D_
<datalist id="cars">_x000D_
  <option>Volvo</option>_x000D_
  <option>Saab</option>_x000D_
  <option>Mercedes</option>_x000D_
  <option>Audi</option>_x000D_
</datalist>

So personally I'm not sure of the best-method way, but one thing I have found works well for vertical alignment is using Flex, as you can justify it's content!

Let's say you have the following HTML and CSS:

.paragraph { 
      font-weight: light;
      color: gray;
      min-height: 6rem;
      background: lightblue;
  }

<h1 class="heading"> Nice to meet you! </h1>
<p class="paragraph"> This is a paragraph </p>

We end up with a paragraph that isn't vertically centered, now if we use a Flex Column and apply the min height + BG to that we get the following:

.myflexbox {
    min-height: 6rem;
    display: flex;
    flex-direction: column;
    justify-content: center;
    background: lightblue;
}

.paragraph { 
      font-weight: light;
      color: gray;
  }

<h1 class="heading"> Nice to meet you! </h1>
<div class="myflexbox">
    <p class="paragraph"> This is a paragraph </p>
</div>

However, in some situations you can't just wrap the P tag in a div so easily, well using Flexbox on the P tag is perfectly fine even if it's not the nicest practice.

.myflexparagraph {
    min-height: 6rem;
    display: flex;
    flex-direction: column;
    justify-content: center;
    background: lightblue;
}

.paragraph { 
      font-weight: light;
      color: gray;
  }

<h1 class="heading"> Nice to meet you! </h1>
<p class="paragraph myflexparagraph"> This is a paragraph </p>

I have no clue if this is good or bad but if this helps only one person somewhere that's still one more then naught!

I think this is the easiest way to do this:

class MyController extends Controller
{
    public function myAction($_route)
    {
        var_dump($_route);
    }

    .....

I know this is a little late, however for anyone interested, I've created a custom component that is basically a toggle image button, the drawable can have states as well as the background

https://gist.github.com/akshaydashrath/9662072

just use a label tag, that way you can hide the input, and make it work through its related label https://developer.mozilla.org/fr/docs/Web/HTML/Element/Label

window.location.href = 'file://///fileserver/upload/Old_Upload/05_06_2019/THRESHOLD/BBH/Look/chrs/Delia';

Nothing Worked for me.

There isn't one, sadly; the IDENTITY property belongs to the table rather than the column.

The easier way is to do it in the GUI, but if this isn't an option, you can go the long way around of copying the data, dropping the column, re-adding it with identity, and putting the data back.

See here for a blow-by-blow account.

int index= datagridview.rows.add();
datagridview.rows[index].cells[1].value=1;
datagridview.rows[index].cells[2].value="a";
datagridview.rows[index].cells[3].value="b";

hope this help! :)

Try

\d \w |\d

or add a positive lookahead if you don't want to include the trailing space in the match

\d \w(?= )|\d

When you have two alternatives where one is an extension of the other, put the longer one first, otherwise it will have no opportunity to be matched.

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.

In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.

Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.

jQuery .on method is used to bind events even without the presence of element on page load. Here is the link It is used in this way:

 $("#dataTable tbody tr").on("click", function(event){
    alert($(this).text());
 });

Before jquery 1.7, .live() method was used, but it is deprecated now.

I know the question is already answered, but I find that the existing answers are not valid:
they will return True for linked tables with a non working back-end.
Using DCount can be much slower, but is more reliable.

Function IsTable(sTblName As String) As Boolean
    'does table exists and work ?
    'note: finding the name in the TableDefs collection is not enough,
    '      since the backend might be invalid or missing

    On Error GoTo hell
    Dim x
    x = DCount("*", sTblName)
    IsTable = True
    Exit Function
hell:
    Debug.Print Now, sTblName, Err.Number, Err.Description
    IsTable = False

End Function

What are you trying to do?

The InterruptedException is thrown when a thread is waiting or sleeping and another thread interrupts it using the interrupt method in class Thread. So if you catch this exception, it means that the thread has been interrupted. Usually there is no point in calling Thread.currentThread().interrupt(); again, unless you want to check the "interrupted" status of the thread from somewhere else.

Regarding your other option of throwing a RuntimeException, it does not seem a very wise thing to do (who will catch this? how will it be handled?) but it is difficult to tell more without additional information.

You cannot mock a final class with Mockito, as you can't do it by yourself.

What I do, is to create a non-final class to wrap the final class and use as delegate. An example of this is TwitterFactory class, and this is my mockable class:

public class TwitterFactory {

    private final twitter4j.TwitterFactory factory;

    public TwitterFactory() {
        factory = new twitter4j.TwitterFactory();
    }

    public Twitter getInstance(User user) {
        return factory.getInstance(accessToken(user));
    }

    private AccessToken accessToken(User user) {
        return new AccessToken(user.getAccessToken(), user.getAccessTokenSecret());
    }

    public Twitter getInstance() {
        return factory.getInstance();
    }
}

The disadvantage is that there is a lot of boilerplate code; the advantage is that you can add some methods that may relate to your application business (like the getInstance that is taking a user instead of an accessToken, in the above case).

In your case I would create a non-final RainOnTrees class that delegate to the final class. Or, if you can make it non-final, it would be better.

There are various ways of changing the status bar color.

1) Using the styles.xml. You can use the android:statusBarColor attribute to do this the easy but static way.

Note: You can also use this attribute with the Material theme.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="AppTheme.Base">
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

2) You can get it done dynamically using the setStatusBarColor(int) method in the Window class. But remember that this method is only available for API 21 or higher. So be sure to check that, or your app will surely crash in lower devices.

Here is a working example of this method.

if (Build.VERSION.SDK_INT >= 21) {
            Window window = getWindow();
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            window.setStatusBarColor(getResources().getColor(R.color.primaryDark));
}

where primaryDark is the 700 tint of the primary color I am using in my app. You can define this color in the colors.xml file.

Do give it a try and let me know if you have any questions. Hope it helps.

Everything seems to be perfect in your code except the fact that handleClick() isn't working because this function lacks a parameter in its function call invocation(but the function definition within has an argument which makes a function mismatch to occur).

The following is a sample working code for calculating all semester's total marks and corresponding grade. It demonstrates the use of a JavaScript function(call) within a html file and also solves the problem you are facing.

  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

I want to preface this by saying I don't know much about writing code/script/etc. but thought I'd share a solution I seem to have come up with. Most of the responses here kinda went over my head, so I was curious to know if what I've written is comparable.

@echo off

set stringLength=0

call:stringEater "It counts most characters"
echo %stringLength%
echo.&pause&goto:eof

if "%n%"=="" (
        goto:eof
    ) else if "%n%"==" " (

Reimeus is right, you see this because of in.close in your chooseCave(). Also, this is wrong.

if (playAgain == "yes") {
      play = true;
}

You should use equals instead of "==".

if (playAgain.equals("yes")) {
      play = true;
}

write a button tag and on click function

var x = document.getElementById('codeRefer').innerHTML;
  document.getElementById('codeRefer').innerHTML = x;

write this all in onclick function

I added TO_DATE and it resolved issue.

Before modification - due to below condition i got this error

record_update_dt>='05-May-2017'

After modification - after adding to_date, issue got resolved.

record_update_dt>=to_date('05-May-2017','DD-Mon-YYYY')

I am late to the game but I found a nice solution. I created a custom attribute directive all you need to do is pass in the gridApi and it will automatically calculate the height. It also subscribes to the pagination change event so if the user changes page size it will resize.

class UIGridAutoResize implements ng.IDirective {
    link: (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => void;
    scope: { gridApi: "=" };
    restrict = "A";

    private previousValue: string;
    private isValid: boolean = true;
    private watch: any;

    constructor($timeout: ng.ITimeoutService) {
        UIGridAutoResize.prototype.link = (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => {
            const gridOptions = scope.$eval(attrs.uiGrid) as any;
            const gridApi = scope.$eval(attrs.gridResize) as any;

            gridApi.core.on.rowsRendered(scope, () => {
                $timeout(() => {
                    this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
                }, 100);
            });

            gridApi.core.on.filterChanged(scope, () => {
                this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
            });

            if (attrs.uiGridPagination === "") {
                gridApi.pagination.on.paginationChanged(null, () => {
                    this.autoSizeGrid(element, attrs, gridOptions, gridApi, true);
                });

Example 3 in the Ruby's net/http documentation shows how to download a document over HTTP, and to output the file instead of just loading it into memory, substitute puts with a binary write to a file, e.g. as shown in Dejw's answer.

More complex cases are shown further down in the same document.

This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)

turning it back to 1.0.7 solved the problem instantly.

have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.

anyway, this problem is fixed when using AngularJS vs 1.0.7.

In my case, I was looking for a solution that allows one of the navbar items to be right aligned. In order to do this, you must add style="width:100%;" to the <ul class="navbar-nav"> and then add the ml-auto class to your navbar item.

When talking about "bad input", you should consider where the input is coming from.

Is the input entered by a user or another external system you don't control, you should expect the input to be invalid, and always validate it. It's perfectly ok to throw a checked exception in this case. Your application should 'recover' from this exception by providing an error message to the user.

If the input originates from your own system, e.g. your database, or some other parts of your application, you should be able to rely on it to be valid (it should have been validated before it got there). In this case it's perfectly ok to throw an unchecked exception like an IllegalArgumentException, which should not be caught (in general you should never catch unchecked exceptions). It is a programmer's error that the invalid value got there in the first place ;) You need to fix it.

A quick look through the documentation on regular expression sytanx should bring up ways to tell if it contains a lower/upper case character at some point.

why not use background-color: #ff0000; opacity: 0.5; filter: alpha(opacity=50); /* in IE */

if you target a color for a text or probably an element, this should be a lot easier to do.

In building a custom set of layout tags, I found another answer to this problem. Provided here is the custom set of tags and their CSS classes.

HTML

<layout-table>
   <layout-header> 
       <layout-column> 1 a</layout-column>
       <layout-column>  </layout-column>
       <layout-column> 3 </layout-column>
       <layout-column> 4 </layout-column>
   </layout-header>

   <layout-row> 
       <layout-column> a </layout-column>
       <layout-column> a 1</layout-column>
       <layout-column> a </layout-column>
       <layout-column> a </layout-column>
   </layout-row>

   <layout-footer> 
       <layout-column> 1 </layout-column>
       <layout-column>  </layout-column>
       <layout-column> 3 b</layout-column>
       <layout-column> 4 </layout-column>
   </layout-footer>
</layout-table>

CSS

layout-table
{
    display : table;
    clear : both;
    table-layout : fixed;
    width : 100%;
}

layout-table:unresolved
{
    color : red;
    border: 1px blue solid;
    empty-cells : show;
}

layout-header, layout-footer, layout-row 
{
    display : table-row;
    clear : both;   
    empty-cells : show;
    width : 100%;
}

layout-column 
{ 
    display : table-column;
    float : left;
    width : 25%;
    min-width : 25%;
    empty-cells : show;
    box-sizing: border-box;
    /* border: 1px solid white; */
    padding : 1px 1px 1px 1px;
}

layout-row:nth-child(even)
{ 
    background-color : lightblue;
}

layout-row:hover 
{ background-color: #f5f5f5 }

The key here is the Box-Sizing and Padding.

I am using mixed solution (php+css).

Containers are needed for:

• div.imgCont2 container needed to rotate;
• div.imgCont1 container needed to zoomOut - width:150%;
• div.imgCont container needed for scrollbars, when image is zoomOut.

.

<?php
    $image_url = 'your image url.jpg';
    $exif = @exif_read_data($image_url,0,true);
    $orientation = @$exif['IFD0']['Orientation'];
?>

<style>
.imgCont{
    width:100%;
    overflow:auto;
}
.imgCont2[data-orientation="8"]{
    transform:rotate(270deg);
    margin:15% 0;
}
.imgCont2[data-orientation="6"]{
    transform:rotate(90deg);
    margin:15% 0;
}
.imgCont2[data-orientation="3"]{
    transform:rotate(180deg);
}
img{
    width:100%;
}
</style>

<div class="imgCont">
  <div class="imgCont1">
    <div class="imgCont2" data-orientation="<?php echo($orientation) ?>">
      <img src="<?php echo($image_url) ?>">
    </div>
  </div>
</div>

In C++20 you'll be able to do:

std::cout << std::format("{:03}", 25); // prints 025

In the meantime you can use the {fmt} library, std::format is based on.

Disclaimer: I'm the author of {fmt} and C++20 std::format.

I have the same problem with a element in a webform. So what I did to fix it was validate. if(Object === 'null') do something

Just in case if you have a loop or a json string that need to insert in the database. Try to replace the string with a single quote . here is my solution. example if you have a string that contain's a single quote.

String mystring = "Sample's";
String myfinalstring = mystring.replace("'","''");

 String query = "INSERT INTO "+table name+" ("+field1+") values ('"+myfinalstring+"')";

this works for me in c# and java

Both array_push and the method you described will work.

$cart = array();
$cart[] = 13;
$cart[] = 14;
// etc

//Above is correct. but below one is for further understanding
$cart = array();
for($i=0;$i<=5;$i++){
    $cart[] = $i;  
}
echo "<pre>";
print_r($cart);
echo "</pre>";

Is the same as:

<?php
$cart = array();
array_push($cart, 13);
array_push($cart, 14);

// Or 
$cart = array();
array_push($cart, 13, 14);
?>

LinearLayout YOUR_LinearLayout =(LinearLayout)findViewById(R.id.YOUR_LinearLayout)
    LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
                       /*width*/ ViewGroup.LayoutParams.MATCH_PARENT,
               /*height*/ 100,
               /*weight*/ 1.0f
                );
                YOUR_LinearLayout.setLayoutParams(param);

Converting Integer to Long Very Simple and many ways to converting that
Example 1

 new Long(your_integer);

Example 2

Long.valueOf(your_integer); 

Example 3

Long a = 12345L;

Example 4
If you already have the int typed as an Integer you can do this:

Integer y = 12;
long x = y.longValue();

I have noticed api example code contains an example of barchart with the value of the bar displayed on each bar:

"""
========
Barchart
========

A bar plot with errorbars and height labels on individual bars
"""
import numpy as np
import matplotlib.pyplot as plt

N = 5
men_means = (20, 35, 30, 35, 27)
men_std = (2, 3, 4, 1, 2)

ind = np.arange(N)  # the x locations for the groups
width = 0.35       # the width of the bars

fig, ax = plt.subplots()
rects1 = ax.bar(ind, men_means, width, color='r', yerr=men_std)

women_means = (25, 32, 34, 20, 25)
women_std = (3, 5, 2, 3, 3)
rects2 = ax.bar(ind + width, women_means, width, color='y', yerr=women_std)

# add some text for labels, title and axes ticks
ax.set_ylabel('Scores')
ax.set_title('Scores by group and gender')
ax.set_xticks(ind + width / 2)
ax.set_xticklabels(('G1', 'G2', 'G3', 'G4', 'G5'))

ax.legend((rects1[0], rects2[0]), ('Men', 'Women'))


def autolabel(rects):
    """
    Attach a text label above each bar displaying its height
    """
    for rect in rects:
        height = rect.get_height()
        ax.text(rect.get_x() + rect.get_width()/2., 1.05*height,
                '%d' % int(height),
                ha='center', va='bottom')

autolabel(rects1)
autolabel(rects2)

plt.show()

output:

FYI What is the unit of height variable in "barh" of matplotlib? (as of now, there is no easy way to set a fixed height for each bar)

Not an answer, but perhpas of interest. I did send a proposal to the CSS WG a few years ago. However, nothing has happened. If indeed they (and browser vendors) would see this as a genuine developer concern, perhaps the ball could start rolling?

If you don't have to worry about any other changes you made and you just want to go back to the last commit, then you can do:

git reset .
git checkout .
git clean -f

If the activity created by yourself, you can try this in the Activity:

@Override
public void setRequestedOrientation(int requestedOrientation) {
    try {
        super.setRequestedOrientation(requestedOrientation);
    } catch (IllegalStateException e) {
        // Only fullscreen activities can request orientation
        e.printStackTrace();
    }
}

This should be the easiest solution.

The best solution I found was to go ahead and create a Table-Valued Function in SQL that produces the results, such as ::

CREATE function [dbo].[getMatches](@textStr nvarchar(50)) returns @MatchTbl table(
Fullname nvarchar(50) null,
ID nvarchar(50) null
)
as begin
declare @SearchStr nvarchar(50);
set @SearchStr = '%' + @textStr + '%';
insert into @MatchTbl 
select (LName + ', ' + FName + ' ' + MName) AS FullName, ID = ID from employees where LName like @SearchStr;
return;
end

GO

select * from dbo.getMatches('j')

Then, you simply drag the function into your LINQ.dbml designer and call it like you do your other objects. The LINQ even knows the columns of your stored function. I call it out like this ::

Dim db As New NobleLINQ
Dim LNameSearch As String = txt_searchLName.Text
Dim hlink As HyperLink

For Each ee In db.getMatches(LNameSearch)
   hlink = New HyperLink With {.Text = ee.Fullname & "<br />", .NavigateUrl = "?ID=" & ee.ID}
   pnl_results.Controls.Add(hlink)
Next

Incredibly simple and really utlizes the power of SQL and LINQ in the application...and you can, of course, generate any table valued function you want for the same effects!

For windows, you need to download the latest version of the open SSL binaries at this time is:

openssl-1.0.2k-x64_86-win64.zip

this problem happened to me when I tried to run MongoDB bin in windows 10

source to download: https://indy.fulgan.com/SSL/

SELECT TOP 2 [Id] FROM table

ToString("X2") prints the input in Hexadecimal

You can set the hours, minutes, seconds and microseconds to whatever you like

datetime.datetime.today().replace(hour=0, minute=0, second=0, microsecond=0)

but trutheality's answer is probably best when they are all to be zero and you can just compare the .date()s of the times

Maybe it is faster though if you have to compare hundreds of datetimes because you only need to do the replace() once vs hundreds of calls to date()

Use CALL as in

CALL nameOfOtherFile.bat

This will block (pause) the execution of the current batch file, and it will wait until the CALLed one completes.

If you don't want it to block, use START instead.

Get the nitty-gritty details by using CALL /? or START /? from the cmd prompt.

I was facing the same issue, but i have successfully handled with async await.
Please check if it helps.

let dataLength = 25;
Before:
  for (let i = 0; i < dataLength; i++) {
      sftp.get(remotePath, fs.createWriteStream(xyzProject/${data[i].name}));
  }

After:
  for (let i = 0; i < dataLength; i++) {
      await sftp.get(remotePath, fs.createWriteStream(xyzProject/${data[i].name}));
  }

Another Kotlin code

class DynamicViewPager @JvmOverloads constructor(
    context: Context,
    attrs: AttributeSet? = null
) : ViewPager(context, attrs) {

    override fun onMeasure(widthMeasureSpec: Int, heightMeasureSpec: Int) {
        var height = 0
        (0 until childCount).forEach {
            val child = getChildAt(it)
            child.measure(
                widthMeasureSpec,
                MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)
            )
            height = max(height, child.measuredHeight)
        }

Replace: String webServiceUrl = "http://localhost:8080/Service1.asmx"

With : String webServiceUrl = "http://10.0.2.2:8080/Service1.asmx"

Good luck!

Hopefully this is the simplest way

 string Commaseplist;
 string[] itemList = { "Test1", "Test2", "Test3" };
 Commaseplist = string.join(",",itemList);
 Console.WriteLine(Commaseplist); //Outputs Test1,Test2,Test3

You should use response.content in this case:

with open('/tmp/metadata.pdf', 'wb') as f:
    f.write(response.content)

From the document:

You can also access the response body as bytes, for non-text requests:

>>> r.content
b'[{"repository":{"open_issues":0,"url":"https://github.com/...

So that means: response.text return the output as a string object, use it when you're downloading a text file. Such as HTML file, etc.

And response.content return the output as bytes object, use it when you're downloading a binary file. Such as PDF file, audio file, image, etc.

You can also use response.raw instead. However, use it when the file which you're about to download is large. Below is a basic example which you can also find in the document:

import requests

url = 'http://www.hrecos.org//images/Data/forweb/HRTVBSH.Metadata.pdf'
r = requests.get(url, stream=True)

with open('/tmp/metadata.pdf', 'wb') as fd:
    for chunk in r.iter_content(chunk_size):
        fd.write(chunk)

chunk_size is the chunk size which you want to use. If you set it as 2000, then requests will download that file the first 2000 bytes, write them into the file, and do this again, again and again, unless it finished.

So this can save your RAM. But I'd prefer use response.content instead in this case since your file is small. As you can see use response.raw is complex.

• How to download image using requests

Just recently, I also encountered similar problem, and after I did this, it works:

I edited the file in /etc/profile

Not quite sure about m2repository part, in the first try it pass the grandle but there is another error (gradlew-command-failed-with-exit-code-

1. I check if in android studio the repository is active, and it's not active, I try to activate it, and when I try it again (Cordova build Android), it download a few other file, maybe from the repository? And then when I delete the path, it still works. (also thanks to Marcin Orlowski sample so then I can understand about export path better).

I use:

From JQuery Documentation

The jqXHR objects returned by $.ajax() as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax() request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:

jqXHR.done(function( data, textStatus, jqXHR ) {});

An alternative construct to the success callback option, refer to deferred.done() for implementation details.

jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});

An alternative construct to the error callback option, the .fail() method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.

jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { }); 

(added in jQuery 1.6) An alternative construct to the complete callback option, the .always() method replaces the deprecated .complete() method.

In response to a successful request, the function's arguments are the same as those of .done(): data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail(): the jqXHR object, textStatus, and errorThrown. Refer to deferred.always() for implementation details.

jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});

Incorporates the functionality of the .done() and .fail() methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then() for implementation details.

Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

If you have problems using System.Diagnostics like I had, use the following simple code that will work without it:

using System.Diagnostics;

Process notePad = new Process();
notePad.StartInfo.FileName   = "notepad.exe";
notePad.StartInfo.Arguments = "mytextfile.txt";
notePad.Start();

you mean that you want to add DatePicker widget into your apps.

Global variable declaration into your activity class:

private Button mPickDate;
private int mYear;
private int mMonth;
private int mDay;
static final int DATE_DIALOG_ID = 0;

write down this code into onCreate() function:

//date picker presentation
    mPickDate = (Button) findViewById(R.id.pickDate);//button for showing date picker dialog 
    mPickDate.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) { showDialog(DATE_DIALOG_ID); }
    });

    // get the current date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);


    // display the current date
    updateDisplay();

write down those function outside of onCreate() function:

//return date picker dialog
@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
    }
    return null;
}

//update month day year

Based on some of the answers here, I have written a CustomConstructorResolver for use in a current project, and I thought it might help somebody else.

It supports the following resolution mechanisms, all configurable:

• Select a single private constructor so you can define one private constructor without having to mark it with an attribute.
• Select the most specific private constructor so you can have multiple overloads, still without having to use attributes.
• Select the constructor marked with an attribute of a specific name - like the default resolver, but without a dependency on the Json.Net package because you need to reference Newtonsoft.Json.JsonConstructorAttribute.

public class CustomConstructorResolver : DefaultContractResolver
{
    public string ConstructorAttributeName { get; set; } = "JsonConstructorAttribute";
    public bool IgnoreAttributeConstructor { get; set; } = false;
    public bool IgnoreSinglePrivateConstructor { get; set; } = false;
    public bool IgnoreMostSpecificConstructor { get; set; } = false;

    protected override JsonObjectContract CreateObjectContract(Type objectType)
    {
        var contract = base.CreateObjectContract(objectType);

        // Use default contract for non-object types.
        if (objectType.IsPrimitive || objectType.IsEnum) return contract;

        // Look for constructor with attribute first, then single private, then most specific.
        var overrideConstructor = 
               (this.IgnoreAttributeConstructor ? null : GetAttributeConstructor(objectType)) 
            ?? (this.IgnoreSinglePrivateConstructor ? null : GetSinglePrivateConstructor(objectType)) 
            ?? (this.IgnoreMostSpecificConstructor ? null : GetMostSpecificConstructor(objectType));

        // Set override constructor if found, otherwise use default contract.
        if (overrideConstructor != null)
        {
            SetOverrideCreator(contract, overrideConstructor);
        }

        return contract;
    }

    private void SetOverrideCreator(JsonObjectContract contract, ConstructorInfo attributeConstructor)
    {
        contract.OverrideCreator = CreateParameterizedConstructor(attributeConstructor);
        contract.CreatorParameters.Clear();
        foreach (var constructorParameter in base.CreateConstructorParameters(attributeConstructor, contract.Properties))
        {
            contract.CreatorParameters.Add(constructorParameter);
        }
    }

    private ObjectConstructor<object> CreateParameterizedConstructor(MethodBase method)
    {
        var c = method as ConstructorInfo;
        if (c != null)
            return a => c.Invoke(a);
        return a => method.Invoke(null, a);
    }

    protected virtual ConstructorInfo GetAttributeConstructor(Type objectType)
    {
        var constructors = objectType
            .GetConstructors(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
            .Where(c => c.GetCustomAttributes().Any(a => a.GetType().Name == this.ConstructorAttributeName)).ToList();

        if (constructors.Count == 1) return constructors[0];
        if (constructors.Count > 1)
            throw new JsonException($"Multiple constructors with a {this.ConstructorAttributeName}.");

        return null;
    }

    protected virtual ConstructorInfo GetSinglePrivateConstructor(Type objectType)
    {
        var constructors = objectType
            .GetConstructors(BindingFlags.Instance | BindingFlags.NonPublic);

        return constructors.Length == 1 ? constructors[0] : null;
    }

    protected virtual ConstructorInfo GetMostSpecificConstructor(Type objectType)
    {
        var constructors = objectType
            .GetConstructors(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic)
            .OrderBy(e => e.GetParameters().Length);

        var mostSpecific = constructors.LastOrDefault();
        return mostSpecific;
    }
}

Feedback appreciated.

What you can do is use WMI to get the paths. This will allow you to get the path regardless it's a 32-bit or 64-bit application. Here's an example demonstrating how you can get it:

// include the namespace
using System.Management;

var wmiQueryString = "SELECT ProcessId, ExecutablePath, CommandLine FROM Win32_Process";
using (var searcher = new ManagementObjectSearcher(wmiQueryString))
using (var results = searcher.Get())
{
    var query = from p in Process.GetProcesses()
                join mo in results.Cast<ManagementObject>()
                on p.Id equals (int)(uint)mo["ProcessId"]
                select new
                {
                    Process = p,
                    Path = (string)mo["ExecutablePath"],
                    CommandLine = (string)mo["CommandLine"],
                };
    foreach (var item in query)
    {
        // Do what you want with the Process, Path, and CommandLine
    }
}

Note that you'll have to reference the System.Management.dll assembly and use the System.Management namespace.

For more info on what other information you can grab out of these processes such as the command line used to start the program (CommandLine), see the Win32_Process class and WMI .NET for for more information.

Just wanted to add that the "run a webserver" answer seems quite daunting, but if you have python on your system (installed by default at least on MacOS and any Linux distribution) it's as easy as:

python -m http.server  # with python3

or

python -m SimpleHTTPServer  # with python2

So if you have your html file myfile.html in a folder, say mydir, all you have to do is:

cd /path/to/mydir
python -m http.server  # or the python2 alternative above

Then point your browser to:

http://localhost:8000/myfile.html

And you are done! Works on all browsers, without disabling web security, allowing local files, or even restarting the browser with command line options.

Just because you use a buffer doesn't mean the stream has to fill that buffer. In other words, this should be okay:

public static void copyStream(InputStream input, OutputStream output)
    throws IOException
{
    byte[] buffer = new byte[1024]; // Adjust if you want
    int bytesRead;
    while ((bytesRead = input.read(buffer)) != -1)
    {
        output.write(buffer, 0, bytesRead);
    }
}

That should work fine - basically the read call will block until there's some data available, but it won't wait until it's all available to fill the buffer. (I suppose it could, and I believe FileInputStream usually will fill the buffer, but a stream attached to a socket is more likely to give you the data immediately.)

I think it's worth at least trying this simple solution first.

Check out Swing Dialogs (mainly focused on JOptionPane, as mentioned by @mcfinnigan).

So I finally found the solution myself.

Firstly I went into terminal and typed:

mysql -u root -p

This asked for my current password which I typed in and it gave me access to provide more mysql commands. Anything I tried from here gave this error:

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

This is confusing because I couldn't actually see a way of resetting the password using ALTER USER statement, but I did find another simple solution:

SET PASSWORD = PASSWORD('xxxxxxxx');

I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:

public static void main(String[] args) {
    try {
        throw new RuntimeException("Cannot move file");
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
    }
}

...you will see a popup that says exactly what you want.

However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause:

public static void main(String[] args) {
    try {
        throw new Exception(new RuntimeException("Cannot move file"));
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(null,
                                      "Error: " + getRootCause(ex).getMessage());
    }
}

public static Throwable getRootCause(Throwable throwable) {
    if (throwable.getCause() != null)
        return getRootCause(throwable.getCause());

    return throwable;
}

Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.

If you only need to share data between views/scopes/controllers, the easiest way is to store it in $rootScope. However, if you need a shared function, it is better to define a service to do that.

#define NAME(x) printf("Hello " #x);
main(){
    NAME(Ian)
}
//will print: Hello Ian

The IV that your using for decryption is incorrect. Replace this code

//Decrypt cipher
Cipher decryptCipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
IvParameterSpec ivParameterSpec = new IvParameterSpec(aesKey.getEncoded());
decryptCipher.init(Cipher.DECRYPT_MODE, aesKey, ivParameterSpec);

With this code

//Decrypt cipher
Cipher decryptCipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
IvParameterSpec ivParameterSpec = new IvParameterSpec(encryptCipher.getIV());
decryptCipher.init(Cipher.DECRYPT_MODE, aesKey, ivParameterSpec);

And that should solve your problem.

Below includes an example of a simple AES class in Java. I do not recommend using this class in production environments, as it may not account for all of the specific needs of your application.

        final String[] shadowData = shadowEntry.split(":");        
        final String base64Iv = shadowData[0];
        final String base64Ciphertext = shadowData[1];

        //Decrypt data and do something with it.
        final byte[] decryptedBytes = AES.decrypt(keyBytes, ivBytes, encryptedBytes);

        //Use non-blocking SecureRandom implementation for the new IV.
        final SecureRandom secureRandom = new SecureRandom();

        //Generate a new IV.
        secureRandom.nextBytes(ivBytes);

        //At this point instead of printing to the screen, 
        //one should replace the old shadow entry with the new one.
        System.out.println("Old Shadow Entry      = " + shadowEntry);
        System.out.println("Decrytped Shadow Data = " + new String(decryptedBytes, StandardCharsets.UTF_8));
        System.out.println("New Shadow Entry      = " + Base64.getEncoder().encodeToString(ivBytes) + ":" + Base64.getEncoder().encodeToString(AES.encrypt(keyBytes, ivBytes, decryptedBytes)));
    }
}

Note that AES has nothing to do with encoding, which is why I chose to handle it separately and without the need of any third party libraries.

We can clear EditText data in two ways

First One setting EditText is empty like below line

editext.setText("");

Second one clearing EditText data like this

editText.getText().clear();

I suggest second way

If you use Express 4.x, you can use the req.get(headerName) method as described in Express 4.x API Reference

Password is a reserved word. Bracket that field name to avoid confusing the db engine.

INSERT into Login (Username, [Password])

document.onkeydown = function(e) {
    switch(e.which) {
        case 37: // left
        break;

        case 38: // up
        break;

        case 39: // right
        break;

        case 40: // down
        break;

        default: return; // exit this handler for other keys
    }
    e.preventDefault(); // prevent the default action (scroll / move caret)
};

If you need to support IE8, start the function body as e = e || window.event; switch(e.which || e.keyCode) {.

(edit 2020)
Note that KeyboardEvent.which is now deprecated. See this example using KeyboardEvent.key for a more modern solution to detect arrow keys.

Just because I haven't seen one this small, here's a dict that gets as nested as you like, no sweat:

# yo dawg, i heard you liked dicts                                                                      
def yodict():
    return defaultdict(yodict)

Create Dynamic angular variables from results

angular.forEach(results, function (value, key) {          
  if (key != null) {                       
    $parse(key).assign($scope, value);                                
  }          
});

ps. don't forget to pass in the $parse attribute into your controller's function

Nicely explained above!

For all those who may suffer like me to get this working in a localized Windows (mine is XP in Slovak), you may try to replace the % with a !

So:

SET TEXT=Hello World
SET SUBSTRING=!TEXT:~3,5!
ECHO !SUBSTRING!

For someone who need to update the PHP version in WAMP, I can recommend this http://wampserver.aviatechno.net/

I had a problems with updating too, but on this website are Wampserver addons like new php version (php 7.1.4 etc.) And you don't have to manually edit files like php.ini or phpForApache.

Enjoy!

If you want to call JavaScript function in C#, this will help you:

public string functionname(arg)
{
    if (condition)
    {
        Page page = HttpContext.Current.CurrentHandler as Page;
        page.ClientScript.RegisterStartupScript(
            typeof(Page),
            "Test",
            "<script type='text/javascript'>functionname1(" + arg1 + ",'" + arg2 + "');</script>");
    }
}

You should not need to query the database directly for the current ApplicationUser.

That introduces a new dependency of having an extra context for starters, but going forward the user database tables change (3 times in the past 2 years) but the API is consistent. For example the users table is now called AspNetUsers in Identity Framework, and the names of several primary key fields kept changing, so the code in several answers will no longer work as-is.

Another problem is that the underlying OWIN access to the database will use a separate context, so changes from separate SQL access can produce invalid results (e.g. not seeing changes made to the database). Again the solution is to work with the supplied API and not try to work-around it.

The correct way to access the current user object in ASP.Net identity (as at this date) is:

var user = UserManager.FindById(User.Identity.GetUserId());

or, if you have an async action, something like:

var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());

FindById requires you have the following using statement so that the non-async UserManager methods are available (they are extension methods for UserManager, so if you do not include this you will only see FindByIdAsync):

using Microsoft.AspNet.Identity;

If you are not in a controller at all (e.g. you are using IOC injection), then the user id is retrieved in full from:

System.Web.HttpContext.Current.User.Identity.GetUserId();

If you are not in the standard Account controller you will need to add the following (as an example) to your controller:

1. Add these two properties:

    /// <summary>
    /// Application DB context
    /// </summary>
    protected ApplicationDbContext ApplicationDbContext { get; set; }

    /// <summary>
    /// User manager - attached to application DB context
    /// </summary>
    protected UserManager<ApplicationUser> UserManager { get; set; }

2. Add this in the Controller's constructor:

    this.ApplicationDbContext = new ApplicationDbContext();
    this.UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(this.ApplicationDbContext));

Update March 2015

Note: The most recent update to Identity framework changes one of the underlying classes used for authentication. You can now access it from the Owin Context of the current HttpContent.

ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());

Addendum:

When using EF and Identity Framework with Azure, over a remote database connection (e.g. local host testing to Azure database), you can randomly hit the dreaded “error: 19 - Physical connection is not usable”. As the cause is buried away inside Identity Framework, where you cannot add retries (or what appears to be a missing .Include(x->someTable)), you need to implement a custom SqlAzureExecutionStrategy in your project.

  margin-top: -.3em;
  margin-bottom: 0em;
}

The only surefire option to find the current session.save_path value is always to check with phpinfo() in exactly the environment where you want to find out the session storage directory.

Reason: there can be all sorts of things that change session.save_path, either by overriding the php.ini value or by setting it at runtime with ini_set('session.save_path','/path/to/folder');. For example, web server management panels like ISPConfig, Plesk etc. often adapt this to give each website its own directory with session files.

Steve McConnell gives an interesting statistic in his book "Software Estimation" (p62 Table 5.2) He distinguish between project types (Avionic, Business, Telco, etc) and project size 10 kLOC, 100 kLOC, 250 kLOC. The numbers are given for each combination in LOC/StaffMonth. E.G. Avionic: 200, 50, 40 Intranet Systems (Internal): 4000, 800, 600 Embedded Systems: 300, 70, 60

Which means: eg. for Avionic 250-kLOC project there are 40 (LOC/Month) / 22 (Days/Month) == <2LOC/day!

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

There's a module for that: https://www.npmjs.com/package/string-to-stream

var str = require('string-to-stream')
str('hi there').pipe(process.stdout) // => 'hi there' 

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

If you're adding a record through ASP.NET, you can use the SqlParameter object to pass in values so you don't have to worry about the apostrophe's that users enter in.

What you see is the interpreter echoing back the return value of next() in addition to i being printed each iteration:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print(i)
...    next(a)
... 
0
1
2
3
4
5
6
7
8
9

So 0 is the output of print(i), 1 the return value from next(), echoed by the interactive interpreter, etc. There are just 5 iterations, each iteration resulting in 2 lines being written to the terminal.

If you assign the output of next() things work as expected:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print(i)
...    _ = next(a)
... 
0
2
4
6
8

or print extra information to differentiate the print() output from the interactive interpreter echo:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print('Printing: {}'.format(i))
...    next(a)
... 
Printing: 0
1
Printing: 2
3
Printing: 4
5
Printing: 6
7
Printing: 8
9

In other words, next() is working as expected, but because it returns the next value from the iterator, echoed by the interactive interpreter, you are led to believe that the loop has its own iterator copy somehow.

This is an old question, but its one I found while searching as well.

You can use git checkout.

I tried the accepted solution but got an error, warning: refname '<tagname>' is ambiguous'

But as the answer states, tags do behave like a pointer to a commit, so as you would with a commit hash, you can just checkout the tag. The only difference is you preface it with tags/:

git checkout tags/<tagname>

In addition to @Emilia Apostolova answer to get the ground truth labels, from

just call

y_true_labels = generator.classes

Signing in Debug Mode

The Android build tools provide a debug signing mode that makes it easier for you to develop and debug your application, while still meeting the Android system requirement for signing your APK. When using debug mode to build your app, the SDK tools invoke Keytool to automatically create a debug keystore and key. This debug key is then used to automatically sign the APK, so you do not need to sign the package with your own key.

The SDK tools create the debug keystore/key with predetermined names/passwords:

Keystore name: "debug.keystore"
Keystore password: "android"
Key alias: "androiddebugkey"
Key password: "android"
CN: "CN=Android Debug,O=Android,C=US"

If necessary, you can change the location/name of the debug keystore/key or supply a custom debug keystore/key to use. However, any custom debug keystore/key must use the same keystore/key names and passwords as the default debug key (as described above). (To do so in Eclipse/ADT, go to Windows > Preferences > Android > Build.)

Caution: You cannot release your application to the public when signed with the debug certificate.

This is how you can add an image view programmatically where you can control the constraints.

Class ViewController: UIViewController {

    let someImageView: UIImageView = {
       let theImageView = UIImageView()
       theImageView.image = UIImage(named: "yourImage.png")
       theImageView.translatesAutoresizingMaskIntoConstraints = false //You need to call this property so the image is added to your view
       return theImageView
    }()

    override func viewDidLoad() {
       super.viewDidLoad()

       view.addSubview(someImageView) //This add it the view controller without constraints
       someImageViewConstraints() //This function is outside the viewDidLoad function that controls the constraints
    }

    // do not forget the `.isActive = true` after every constraint
    func someImageViewConstraints() {
        someImageView.widthAnchor.constraint(equalToConstant: 180).isActive = true
        someImageView.heightAnchor.constraint(equalToConstant: 180).isActive = true
        someImageView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        someImageView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 28).isActive = true
    }

}

for people coming here from the firebase codelabs tutorial step 3:go to page 4.

Apparently, if google says You should now have the android-start project open in Android Studio. ,She means it,and not You should now have the android-start project open in Android Studio, without any build-errors .
As the instruction says there, you have to get a configuration file from firebase. i.e , create a new project in your firebase acc with name 'friendly chat and in the next page , add its package name and SHA1 KEY.
after downloading the json file,add it to your project>app folder, and Rebuild project.

Like others have already said, it's not immediately obvious what you're asking. I'm going to assume that you want to start a process and then perform another action when the process "is ready".

Of course, the "is ready" is the tricky bit. Depending on what you're needs are, you may find that simply waiting is sufficient. However, if you need a more robust solution, you can consider using a named Mutex to control the control flow between your two processes.

For example, in your main process, you might create a named mutex and start a thread or task which will wait. Then, you can start the 2nd process. When that process decides that "it is ready", it can open the named mutex (you have to use the same name, of course) and signal to the first process.

For me fixing was add slash after directory name

var_dump() can do this.

This function displays structured information about one or more expressions that includes its type and value. Arrays and objects are explored recursively with values indented to show structure.

In WSDL, if you look at the Binding section, you will clearly see that soap binding is explicitly mentioned if the service uses soap 1.2. refer the below sample.

<binding name="EmployeeServiceImplPortBinding" type="tns:EmployeeServiceImpl">
<soap12:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<operation name="findEmployeeById">
    <soap12:operation soapAction=""/>
    <input><soap12:body use="literal"/></input>
    <output><soap12:body use="literal"/></output>
</operation><operation name="create">
    <soap12:operation soapAction=""/>
    <input><soap12:body use="literal"/></input>
    <output><soap12:body use="literal"/></output>
</operation>
</binding>

if the web service use soap 1.1, it will not explicitly define any soap version in the WSDL file under binding section. refer the below sample.

<binding name="EmployeeServiceImplPortBinding" type="tns:EmployeeServiceImpl">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"/>
<operation name="findEmployeeById">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></input>
    <output><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></output>
</operation><operation name="create">
    <soap:operation soapAction=""/>
    <input><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></input>
    <output><soap:body use="literal" namespace="http://jaxb.ws.jax.samples.chathurangaonline.com/"/></output>
</operation>
</binding>

How to determine the SOAP version of the SOAP message?

but remember that this is not much recommended way to determine the soap version that your web services uses. the version of the soap message can be determined using one of following ways.

1. checking the namespace of the soap message

SOAP 1.1  namespace : http://schemas.xmlsoap.org/soap/envelope

SOAP 1.2 namespace  : http://www.w3.org/2003/05/soap-envelope

2. checking the transport binding information (http header information) of the soap message

SOAP 1.1 : user text/xml for the Context-Type

   POST /MyService HTTP/1.1
   Content-Type: text/xml; charset="utf-8"
   Content-Length: xxx
   SOAPAction: "urn:uuid:myaction"

SOAP 1.2 : user application/soap+xml for the Context-Type

   POST /MyService HTTP/1.1
   Content-Type: application/soap+xml; charset="utf-8"
   Content-Length: xxx
   SOAPAction: "urn:uuid:myaction"

3. using SOAP fault information

The structure of a SOAP fault message between the two versions are different.

A little old but this works in L5:

<li class="{{ Request::is('mycategory/', '*') ? 'active' : ''}}">

This captures both /mycategory and /mycategory/slug

I solved it this way, I opened the .sql file in a Notepad and clicked CTRL + H to find and replace the string "utf8mb4_0900_ai_ci" and replaced it with "utf8mb4_general_ci".

Just make sure put single space before and after "and" Keyword..

Replace the separator with TAB(\t) instead of comma(,). Then open the file in your editor (Notepad etc.), copy the content from there, then paste it in the Excel file.

The remainder operator, %, will give you the remainder after dividing by a number.

So n % 2 == 0 will be true if n is even and false if n is odd.

After searching stackoverflow and the web a lot, I've got to conclution that the best way of doing it is like this:

- (BOOL)isEndDateIsSmallerThanCurrent:(NSDate *)checkEndDate
{
    NSDate* enddate = checkEndDate;
    NSDate* currentdate = [NSDate date];
    NSTimeInterval distanceBetweenDates = [enddate timeIntervalSinceDate:currentdate];
    double secondsInMinute = 60;
    NSInteger secondsBetweenDates = distanceBetweenDates / secondsInMinute;

    if (secondsBetweenDates == 0)
        return YES;
    else if (secondsBetweenDates < 0)
        return YES;
    else
        return NO;
}

You can change it to difference between hours also.

Enjoy!

Edit 1

If you want to compare date with format of dd/MM/yyyy only, you need to add below lines between NSDate* currentdate = [NSDate date]; && NSTimeInterval distance

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd/MM/yyyy"];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]
                          autorelease]];

NSString *stringDate = [dateFormatter stringFromDate:[NSDate date]];

currentdate = [dateFormatter dateFromString:stringDate];

"Knowing about sites which handles such massive traffic gives lots of pointers for architects etc. to keep in mind certain stuff while designing new sites"

I think you can probably learn a lot from the design of Facebook, just as you can from the design of any successful large software system. However, it seems to me that you should not keep the current design of Facebook in mind when designing new systems.

Why do you want to be able to handle the traffic that Facebook has to handle? Odds are that you will never have to, no matter how talented a programmer you may be. Facebook itself was not designed from the start for such massive scalability, which is perhaps the most important lesson to learn from it.

If you want to learn about a non-trivial software system I can recommend the book "Dissecting a C# Application" about the development of the SharpDevelop IDE. It is out of print, but it is available for free online. The book gives you a glimpse into a real application and provides insights about IDEs which are useful for a programmer.

As devio says there is no way to simply edit a UDT if it's in use.

A work-round through SMS that worked for me was to generate a create script and make the appropriate changes; rename the existing UDT; run the create script; recompile the related sprocs and drop the renamed version.

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

Because I always struggle to remember, a quick summary of what each of these do:

>>> pd.Timestamp.now()  # naive local time
Timestamp('2019-10-07 10:30:19.428748')

>>> pd.Timestamp.utcnow()  # tz aware UTC
Timestamp('2019-10-07 08:30:19.428748+0000', tz='UTC')

>>> pd.Timestamp.now(tz='Europe/Brussels')  # tz aware local time
Timestamp('2019-10-07 10:30:19.428748+0200', tz='Europe/Brussels')

>>> pd.Timestamp.now(tz='Europe/Brussels').tz_localize(None)  # naive local time
Timestamp('2019-10-07 10:30:19.428748')

>>> pd.Timestamp.now(tz='Europe/Brussels').tz_convert(None)  # naive UTC
Timestamp('2019-10-07 08:30:19.428748')

>>> pd.Timestamp.utcnow().tz_localize(None)  # naive UTC
Timestamp('2019-10-07 08:30:19.428748')

>>> pd.Timestamp.utcnow().tz_convert(None)  # naive UTC
Timestamp('2019-10-07 08:30:19.428748')

You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).

By default, imshow sets the aspect of the plot to 1, as this is often what people want for image data.

In your case, you can do something like:

import matplotlib.pyplot as plt
import numpy as np

grid = np.random.random((10,10))

fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))

ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')

ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')

ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')

plt.tight_layout()
plt.show()

Direct answer:

• Use a = operator

We can use the public member function std::vector::operator= of the container std::vector for assigning values from a vector to another.

• Use a constructor function

Besides, a constructor function also makes sense. A constructor function with another vector as parameter(e.g. x) constructs a container with a copy of each of the elements in x , in the same order.

Caution:

• Do not use std::vector::swap

std::vector::swap is not copying a vector to another, it is actually swapping elements of two vectors, just as its name suggests. In other words, the source vector to copy from is modified after std::vector::swap is called, which is probably not what you are expected.

• Deep or shallow copy?

If the elements in the source vector are pointers to other data, then a deep copy is wanted sometimes.

According to wikipedia:

A deep copy, meaning that fields are dereferenced: rather than references to objects being copied, new copy objects are created for any referenced objects, and references to these placed in B.

Actually, there is no currently a built-in way in C++ to do a deep copy. All of the ways mentioned above are shallow. If a deep copy is necessary, you can traverse a vector and make copy of the references manually. Alternatively, an iterator can be considered for traversing. Discussion on iterator is beyond this question.

unanswered core problem persists:

My working directory is now c:\users\projectname.git So then I try to import the project using the eclipse "import" option. When I try to import selecting the option "Use the new projects wizard" the source code is not imported, if I import selecting the option "Import as general project" the source code is imported but the created project created by Eclipse is not a java project. When selecting the option "Use the new projects wizard" and creating a new java project using the wizard should'nt the code be automatically imported ?

Yes it should.

It's a bug. Reported here.

Here is a workaround:

• Import as general project

• Notice the imported data is no valid Eclipse project (no build path available)

• Open the .project xml file in the project folder in Eclipse. If you can't see this file, see How can I get Eclipse to show .* files?.

• Go to source tab

• Search for <natures></natures> and change it to <natures><nature>org.eclipse.jdt.core.javanature</nature></natures> and save the file

  (idea comes from here)

• Right click the src folder, go to Build Path... and click Use as Source Folder

After that, you should be able to run & debug the project, and also use team actions via right-click in the package explorer.

If you still have troubles running the project (something like "main class not found"), make sure the <buildSpec> inside the .project file is set (as described here):

<buildSpec>
    <buildCommand>
        <name>org.eclipse.jdt.core.javabuilder</name>
        <arguments>
        </arguments>
    </buildCommand>
</buildSpec>

DispatchQueue.main.async(execute: {

// write code

})

Serial Queue :

let serial = DispatchQueue(label: "Queuename")

serial.sync { 

 //Code Here

}

Concurrent queue :

 let concurrent = DispatchQueue(label: "Queuename", attributes: .concurrent)

concurrent.sync {

 //Code Here
}

I don't believe there's anything within .NET to allow copying a section of a file without buffering it in memory. However, it strikes me that this is inefficient anyway, as it needs to open the input file and seek many times. If you're just splitting up the file, why not open the input file once, and then just write something like:

public static void CopySection(Stream input, string targetFile, int length)
{
    byte[] buffer = new byte[8192];

    using (Stream output = File.OpenWrite(targetFile))
    {
        int bytesRead = 1;
        // This will finish silently if we couldn't read "length" bytes.
        // An alternative would be to throw an exception
        while (length > 0 && bytesRead > 0)
        {
            bytesRead = input.Read(buffer, 0, Math.Min(length, buffer.Length));
            output.Write(buffer, 0, bytesRead);
            length -= bytesRead;
        }
    }
}

This has a minor inefficiency in creating a buffer on each invocation - you might want to create the buffer once and pass that into the method as well:

public static void CopySection(Stream input, string targetFile,
                               int length, byte[] buffer)
{
    using (Stream output = File.OpenWrite(targetFile))
    {
        int bytesRead = 1;
        // This will finish silently if we couldn't read "length" bytes.
        // An alternative would be to throw an exception
        while (length > 0 && bytesRead > 0)
        {
            bytesRead = input.Read(buffer, 0, Math.Min(length, buffer.Length));
            output.Write(buffer, 0, bytesRead);
            length -= bytesRead;
        }
    }
}

Note that this also closes the output stream (due to the using statement) which your original code didn't.

The important point is that this will use the operating system file buffering more efficiently, because you reuse the same input stream, instead of reopening the file at the beginning and then seeking.

I think it'll be significantly faster, but obviously you'll need to try it to see...

This assumes contiguous chunks, of course. If you need to skip bits of the file, you can do that from outside the method. Also, if you're writing very small files, you may want to optimise for that situation too - the easiest way to do that would probably be to introduce a BufferedStream wrapping the input stream.

script/runner and rake tasks are perfectly fine to run as cron jobs.

Here's one very important thing you must remember when running cron jobs. They probably won't be called from the root directory of your app. This means all your requires for files (as opposed to libraries) should be done with the explicit path: e.g. File.dirname(__FILE__) + "/other_file". This also means you have to know how to explicitly call them from another directory :-)

Check if your code supports being run from another directory with

# from ~
/path/to/ruby /path/to/app/script/runner -e development "MyClass.class_method"
/path/to/ruby /path/to/rake -f /path/to/app/Rakefile rake:task RAILS_ENV=development

Also, cron jobs probably don't run as you, so don't depend on any shortcut you put in .bashrc. But that's just a standard cron tip ;-)

This could be a little tricky thing but the secure way is to set a javascript cookie, then picking it up by php cookie variable.Then Assign this php variable to an php session that will hold the data more securely than cookie.Then delete the cookie using javascript and redirect the page to itself. Given that you have added an php command to catch the variable, you will get it.

There is no need for extra CSS, and there are multiple centering methods in Bootstrap 4:

• text-center for center display:inline elements
• mx-auto for centering display:block elements inside display:flex (d-flex)
• offset-* or mx-auto can be used to center grid columns
• or justify-content-center on row to center grid columns

mx-auto (auto x-axis margins) will center inside display:flex elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various centering methods.

In your case, you can simply mx-auto to the cards.

try:

git diff origin HEAD

Assuming you want to diff you current Local branch's HEAD against the origin. And assuming you are on the local branch. :)

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 $@ $^

I had something similar to this happen in my WPF application. It arose when I was trying to do some cleanup by declaring a namespace that was more descriptive. The problem arose because I had named the namespace in the code-behind (or cs) the same as the Window class. The namespace in the code-behind should have the last section stripped (after the rightmost dot) and used to declare the class and instantiate it. Notice Win below:

xaml

<Window x:Class="FrameApp.UI.Invoice.Win" ...>

code-behind

namespace FrameApp.UI.Invoice
{
    public partial class Win : Window
    {
        public Win()
    }
}

An obvious oversight but it set me back at least an hour with all the errors that appeared.

This question is a bit old - as are the answers (and the tutorial as well)

The current api for setting a popupMenu in Swing is

myComponent.setComponentPopupMenu(myPopupMenu);

This way it will be shown automagically, both for mouse and keyboard triggers (the latter depends on LAF). Plus, it supports re-using the same popup across a container's children. To enable that feature:

myChild.setInheritsPopupMenu(true);

@SolutionYogi's answer works like a charm, but it seems that using $.each is less straightforward and efficient than directly appending listitems :

var mylist = $('#list');
var listitems = mylist.children('li').get();

listitems.sort(function(a, b) {
   return $(a).text().toUpperCase().localeCompare($(b).text().toUpperCase());
})

mylist.empty().append(listitems);

Fiddle

This works for me:

ListBox x = new ListBox();
x.Items.Add(new ListItem("Hello", "1"));
x.Items.Add(new ListItem("Bye", "2"));

Console.Write(x.Items[0].Value);

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var textLbl: UILabel!

    var containerView = UIView()
    var loadingView = UIView()
    var activityIndicator = UIActivityIndicatorView()

    override func viewDidLoad() {
        super.viewDidLoad()

        let _  = Timer.scheduledTimer(withTimeInterval: 10, repeats: false) { (_) in
            self.textLbl.text = "Stop ActivitiIndicator"
            self.activityIndicator.stopAnimating()
            self.containerView.removeFromSuperview()
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    @IBAction func palyClicked(sender: AnyObject){

        containerView.frame = self.view.frame
        containerView.backgroundColor = UIColor(red: 0/255, green: 0/255, blue: 0/255, alpha: 0.3)
        self.view.addSubview(containerView)

        loadingView.frame = CGRect(x: 0, y: 0, width: 80, height: 80)
        loadingView.center = self.view.center
        loadingView.backgroundColor = UIColor(red: 0/255, green: 0/255, blue: 0/255, alpha: 0.5)
        loadingView.clipsToBounds = true
        loadingView.layer.cornerRadius = 10
        containerView.addSubview(loadingView)

        activityIndicator.frame = CGRect(x: 0, y: 0, width: 40, height: 40)
        activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.whiteLarge
        activityIndicator.center = CGPoint(x:loadingView.frame.size.width / 2, y:loadingView.frame.size.height / 2);
        activityIndicator.startAnimating()
        loadingView.addSubview(activityIndicator)

    }
}

Reading between the lines, I think the logic was something like this:

• generally, the Java designers wanted to simplify the repertoire of data types available
• for everyday purposes, they felt that the most common need was for signed data types
• for implementing certain algorithms, unsigned arithmetic is sometimes needed, but the kind of programmers that would be implementing such algorithms would also have the knowledge to "work round" doing unsigned arithmetic with signed data types

Mostly, I'd say it was a reasonable decision. Possibly, I would have:

• made byte unsigned, or at least have provided a signed/unsigned alternatives, possibly with different names, for this one data type (making it signed is good for consistency, but when do you ever need a signed byte?)
• done away with 'short' (when did you last use 16-bit signed arithmetic?)

Still, with a bit of kludging, operations on unsigned values up to 32 bits aren't tooo bad, and most people don't need unsigned 64-bit division or comparison.

I thought it would be beneficial to include what I consider to be a more simple method using numpy's linspace coupled with matplotlib's cm-type object. It's possible that the above solution is for an older version. I am using the python 3.4.3, matplotlib 1.4.3, and numpy 1.9.3., and my solution is as follows.

import matplotlib.pyplot as plt

from matplotlib import cm
from numpy import linspace

start = 0.0
stop = 1.0
number_of_lines= 1000
cm_subsection = linspace(start, stop, number_of_lines) 

colors = [ cm.jet(x) for x in cm_subsection ]

for i, color in enumerate(colors):
    plt.axhline(i, color=color)

plt.ylabel('Line Number')
plt.show()

This results in 1000 uniquely-colored lines that span the entire cm.jet colormap as pictured below. If you run this script you'll find that you can zoom in on the individual lines.

Now say I want my 1000 line colors to just span the greenish portion between lines 400 to 600. I simply change my start and stop values to 0.4 and 0.6 and this results in using only 20% of the cm.jet color map between 0.4 and 0.6.

So in a one line summary you can create a list of rgba colors from a matplotlib.cm colormap accordingly:

colors = [ cm.jet(x) for x in linspace(start, stop, number_of_lines) ]

In this case I use the commonly invoked map named jet but you can find the complete list of colormaps available in your matplotlib version by invoking:

>>> from matplotlib import cm
>>> dir(cm)

You may have better luck breaking the problem down into converting PDF into an editable format, writing your changes, then converting it back into PDF. I don't know of a library that lets you directly edit PDF but there are plenty of converters between DOC and PDF for example.

You can use itertools.cycle:

>>> from itertools import cycle
>>> lis = [[10,13,17],[3,5,1],[13,11,12]]
>>> cyc = cycle((-1, 1))
>>> 50 + sum(x*next(cyc) for x in lis[0])   # lis[0] is [10,13,17]
36

Here the generator expression inside sum would return something like this:

>>> cyc = cycle((-1, 1))
>>> [x*next(cyc) for x in lis[0]]
[-10, 13, -17]

You can also use zip here:

>>> cyc = cycle((-1, 1))
>>> [x*y for x, y  in zip(lis[0], cyc)]
[-10, 13, -17]

Use an object (key/value pairs, the nearest JavaScript has to an associative array) for this and not the array object. Other than that, I believe that is the most elegant way

var foo = {};
foo['alfa'] = "first item";
foo['beta'] = "second item";

for (var key in foo) {
        console.log(key);
}

Note: JavaScript doesn't guarantee any particular order for the properties. So you cannot expect the property that was defined first to appear first, it might come last.

EDIT:

In response to your comment, I believe that this article best sums up the cases for why arrays in JavaScript should not be used in this fashion -

• "Associative Arrays" considered Harmful

function routeToRoom(userId, passw, cb) {
    var roomId = 0;
    var nStore = require('nstore/lib/nstore').extend(require('nstore/lib/nstore/query')());
    var users = nStore.new('data/users.db', function() {
        users.find({
            user: userId,
            pass: passw
        }, function(err, results) {
            if (err) {
                roomId = -1;
            } else {
                roomId = results.creationix.room;
            }
            cb(roomId);
        });
    });
}
routeToRoom("alex", "123", function(id) {
    console.log(id);    
});

You need to use callbacks. That's how asynchronous IO works. Btw sys.puts is deprecated

I just tried these headers and got Excel 2013 on a Windows 7 PC to import the CSV file with special characters correctly. The Byte Order Mark (BOM) was the final key that made it work.

    header('Content-Encoding: UTF-8');
    header('Content-type: text/csv; charset=UTF-8');
    header("Content-disposition: attachment; filename=filename.csv");
    header("Pragma: public");
    header("Expires: 0");
    echo "\xEF\xBB\xBF"; // UTF-8 BOM

Add this

android:gravity="center"

In LinearLayout.

$html = preg_replace('/\sstyle=("|\').*?("|\')/i', '', $html);

There are three basic types of join:

• INNER join compares two tables and only returns results where a match exists. Records from the 1st table are duplicated when they match multiple results in the 2nd. INNER joins tend to make result sets smaller, but because records can be duplicated this isn't guaranteed.
• CROSS join compares two tables and return every possible combination of rows from both tables. You can get a lot of results from this kind of join that might not even be meaningful, so use with caution.
• OUTER join compares two tables and returns data when a match is available or NULL values otherwise. Like with INNER join, this will duplicate rows in the one table when it matches multiple records in the other table. OUTER joins tend to make result sets larger, because they won't by themselves remove any records from the set. You must also qualify an OUTER join to determine when and where to add the NULL values:
  • LEFT means keep all records from the 1st table no matter what and insert NULL values when the 2nd table doesn't match.
  • RIGHT means the opposite: keep all records from the 2nd table no matter what and insert NULL values whent he 1st table doesn't match.
  • FULL means keep all records from both tables, and insert a NULL value in either table if there is no match.

Often you see will the OUTER keyword omitted from the syntax. Instead it will just be "LEFT JOIN", "RIGHT JOIN", or "FULL JOIN". This is done because INNER and CROSS joins have no meaning with respect to LEFT, RIGHT, or FULL, and so these are sufficient by themselves to unambiguously indicate an OUTER join.

Here is an example of when you might want to use each type:

• INNER: You want to return all records from the "Invoice" table, along with their corresponding "InvoiceLines". This assumes that every valid Invoice will have at least one line.
• OUTER: You want to return all "InvoiceLines" records for a particular Invoice, along with their corresponding "InventoryItem" records. This is a business that also sells service, such that not all InvoiceLines will have an IventoryItem.
• CROSS: You have a digits table with 10 rows, each holding values '0' through '9'. You want to create a date range table to join against, so that you end up with one record for each day within the range. By CROSS-joining this table with itself repeatedly you can create as many consecutive integers as you need (given you start at 10 to 1st power, each join adds 1 to the exponent). Then use the DATEADD() function to add those values to your base date for the range.

Try running

lsof | grep /mnt/data

That should list any process that is accessing /mnt/data that would prevent it from being unmounted.

Firebase Cloud Messaging has a server-side APIs that you can call to send messages. See https://firebase.google.com/docs/cloud-messaging/server.

Sending a message can be as simple as using curl to call a HTTP end-point. See https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol

curl -X POST --header "Authorization: key=<API_ACCESS_KEY>" \
    --Header "Content-Type: application/json" \
    https://fcm.googleapis.com/fcm/send \
    -d "{\"to\":\"<YOUR_DEVICE_ID_TOKEN>\",\"notification\":{\"title\":\"Hello\",\"body\":\"Yellow\"}}"

You simply need to use the asset helper function in Laravel. (The url helper can also be used in this manner)

<img src="{{ asset('images/arrow.gif') }}" />

For the absolute path, you use public_path instead.

<p>Absolute path: {{ public_path('images/arrow.gif') }}</p>

If you are providing the URL to a public image from a controller (backend) you can use asset as well, or secure_asset if you want HTTPS. eg:

$url = asset('images/arrow.gif'); # http://example.com/assets/images/arrow.gif
$secure_url = secure_asset('images/arrow.gif'); # https://example.com/assets/images/arrow.gif

return $secure_url;

Lastly, if you want to go directly to the image on a given route you can redirect to it:

return \Redirect::to($secure_url);

More Laravel helper functions can be found here

Short Answer

Use <foreach> with a nested <FileSet>

Foreach requires ant-contrib.

Updated Example for recent ant-contrib:

<target name="foo">
  <foreach target="bar" param="theFile">
    <fileset dir="${server.src}" casesensitive="yes">
      <include name="**/*.java"/>
      <exclude name="**/*Test*"/>
    </fileset>
  </foreach>
</target>

<target name="bar">
  <echo message="${theFile}"/>
</target>

This will antcall the target "bar" with the ${theFile} resulting in the current file.

sudo gem install cocoapods --pre -n /usr/local/bin

You should try doing it with css3 animation. Check the code bellow:

<!DOCTYPE html>
<html>
<head>
<style> 
div {
    width: 100px;
    height: 100px;
    background: red;
    position: relative;
    -webkit-animation: myfirst 5s infinite; /* Chrome, Safari, Opera */
    -webkit-animation-direction: alternate; /* Chrome, Safari, Opera */
    animation: myfirst 5s infinite;
    animation-direction: alternate;
}

/* Chrome, Safari, Opera */
@-webkit-keyframes myfirst {
    0%   {background: red; left: 0px; top: 0px;}
    25%  {background: yellow; left: 200px; top: 0px;}
    50%  {background: blue; left: 200px; top: 200px;}
    75%  {background: green; left: 0px; top: 200px;}
    100% {background: red; left: 0px; top: 0px;}
}

@keyframes myfirst {
    0%   {background: red; left: 0px; top: 0px;}
    25%  {background: yellow; left: 200px; top: 0px;}
    50%  {background: blue; left: 200px; top: 200px;}
    75%  {background: green; left: 0px; top: 200px;}
    100% {background: red; left: 0px; top: 0px;}
}
</style>
</head>
<body>

<p><strong>Note:</strong> The animation-direction property is not supported in Internet Explorer 9 and earlier versions.</p>
<div></div>

Where 'div' is your animated object.

I hope you find this useful.

As an extension to what John said, if you want to extract the string representation and store it in a std::string do this:

#include <sstream>    
// ...
// Suppose a class A
A a;
std::stringstream sstream;
sstream << a;
std::string s = sstream.str(); // or you could use sstream >> s but that would skip out whitespace

std::stringstream is located in the <sstream> header.

For me adding DOCTYPE_PUBLIC worked:

transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC,"yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "10");

simplest way without any intermediate list using list.index():

z = ['a', 'b', 'a', 'c', 'b', 'a', ]
[z[i] for i in range(len(z)) if i == z.index(z[i])]
>>>['a', 'b', 'c']

and you can also list the duplicates itself (may contain duplicates again as in the example):

[z[i] for i in range(len(z)) if not i == z.index(z[i])]
>>>['a', 'b', 'a']

or their index:

[i for i in range(len(z)) if not i == z.index(z[i])]
>>>[2, 4, 5]

or the duplicates as a list of 2-tuples of their index (referenced to their first occurrence only), what is the answer to the original question!!!:

[(i,z.index(z[i])) for i in range(len(z)) if not i == z.index(z[i])]
>>>[(2, 0), (4, 1), (5, 0)]

or this together with the item itself:

[(i,z.index(z[i]),z[i]) for i in range(len(z)) if not i == z.index(z[i])]
>>>[(2, 0, 'a'), (4, 1, 'b'), (5, 0, 'a')]

or any other combination of elements and indices....

Normal ways would be Integer.toString(i) or String.valueOf(i).

int i = 5;
String strI = String.valueOf(i);

Or

int aInt = 1;    
String aString = Integer.toString(aInt);

If you are averse to boost, you can use regular old operator>>, along with std::noskipws:

EDIT: updates after testing.

#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
#include <algorithm>
#include <iterator>
#include <sstream>

void split(const std::string& str, std::vector<std::string>& v) {
  std::stringstream ss(str);
  ss >> std::noskipws;
  std::string field;
  char ws_delim;
  while(1) {
    if( ss >> field )
      v.push_back(field);
    else if (ss.eof())
      break;
    else
      v.push_back(std::string());
    ss.clear();
    ss >> ws_delim;
  }
}

int main() {
  std::vector<std::string> v;
  split("hello world  how are   you", v);
  std::copy(v.begin(), v.end(), std::ostream_iterator<std::string>(std::cout, "-"));
  std::cout << "\n";
}

did you try

indices = Find(strs, 'KU')

see link

alternatively,

indices = strfind(strs, 'KU');

should also work if I'm not mistaken.
