In addition to @delmadord's answer and your comments:

Currently there is no method to create subquery in FROM clause, so you need to manually use raw statement, then, if necessary, you will merge all the bindings:

$sub = Abc::where(..)->groupBy(..); // Eloquent Builder instance

$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )
    ->mergeBindings($sub->getQuery()) // you need to get underlying Query Builder
    ->count();

Mind that you need to merge bindings in correct order. If you have other bound clauses, you must put them after mergeBindings:

$count = DB::table( DB::raw("({$sub->toSql()}) as sub") )

    // ->where(..) wrong

    ->mergeBindings($sub->getQuery()) // you need to get underlying Query Builder

    // ->where(..) correct

    ->count();

I've not noticed any difference in startup time between the 2, but clocked a very minimal improvement in application performance with "-server" (Solaris server, everyone using SunRays to run the app). That was under 1.5.

You can center a fixed or absolute positioned element setting right and left to 0, and then margin-left & margin-right to auto as if you were centering a static positioned element.

#example {
    position: fixed;
    /* center the element */
    right: 0;
    left: 0;
    margin-right: auto;
    margin-left: auto;
    /* give it dimensions */
    min-height: 10em;
    width: 90%;
}

See this example working on this fiddle.

Instead of using to remove a CR/LF between elements, I use the SGML processing instruction because minifiers often remove the comments, but not the XML PI. When the PHP PI is processed by PHP, it has the additional benefit of removing the PI completely along with the CR/LF in between, thus saving at least 8 bytes. You can use any arbitrary valid instruction name such as and save two bytes in X(HT)ML.

I did this:

$('#myModal').on 'shown.bs.modal', (e) ->  
  $(e.target).find('.modal-body').load('http://yourserver.com/content')

>>> list1 = [1,2,3,4,5,6]
>>> list2 = [3, 5, 7, 9]
>>> list(set(list1).intersection(list2))
[3, 5]

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Since you only said render, yes you can. You could do something along the lines of this:

function render(){_x000D_
 var inp     = document.getElementById("box");_x000D_
 var data = `_x000D_
<svg xmlns="http://www.w3.org/2000/svg" width="${inp.offsetWidth}" height="${inp.offsetHeight}">_x000D_
<foreignObject width="100%" height="100%">_x000D_
<div xmlns="http://www.w3.org/1999/xhtml" _x000D_
style="font-family:monospace;font-style: normal; font-variant: normal; font-size:13.3px;padding:2px;;">_x000D_
${inp.value} <i style="color:red">cant touch this</i>_x000D_
</div>_x000D_
</foreignObject>_x000D_
</svg>`;_x000D_
 var blob = new Blob( [data], {type:'image/svg+xml'} );_x000D_
 var url=URL.createObjectURL(blob);_x000D_
 inp.style.backgroundImage="url("+URL.createObjectURL(blob)+")";_x000D_
 }_x000D_
 onload=function(){_x000D_
  render();_x000D_
  ro = new ResizeObserver(render);_x000D_
 ro.observe(document.getElementById("box"));_x000D_
 }

#box{_x000D_
  color:transparent;_x000D_
  caret-color: black;_x000D_
  font-style: normal;/*must be same as in the svg for caret to align*/_x000D_
  font-variant: normal; _x000D_
  font-size:13.3px;_x000D_
  padding:2px;_x000D_
  font-family:monospace;_x000D_
}

<textarea id="box" oninput="render()">you can edit me!</textarea>

Add below code in your client code :

static {
    Security.insertProviderAt(new BouncyCastleProvider(),1);
 }

with this there is no need to add any entry in java.security file.

Here's a nice little Curry which lends better readability (IMHO):

The second function's signature is identical to the Array.prototype.splice method.

function mutate(s) {
    return function splice() {
        var a = s.split('');
        Array.prototype.splice.apply(a, arguments);
        return a.join('');
    };
}

mutate('101')(1, 1, '1');

I know there's already an accepted answer, but hope this is useful.

To keep this simple, I just changed the directory from which I was importing the data to a local folder on the server.

I had the file located on a shared folder, I just copied my files to "c:\TEMP\Reports" on my server (updated the query to BULK INSERT from the new folder). The Agent task completed successfully :)

Finally after a long time I'm able to BULK Insert automatically via agent job.

Best regards.

This guide explains in detail how to deploy Spring Boot app on Tomcat:
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

Essentially I needed to add following class:

public class WebInitializer extends SpringBootServletInitializer {   
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(App.class);
    }    
}

Also I added following property to POM:

<properties>        
    <start-class>mypackage.App</start-class>
</properties>

It is absolutely possible to install side-by-side several JRE/JDK versions. Moreover, you don't have to do anything special for that to happen, as Sun is creating a different folder for each (under Program Files).

There is no control panel to check which JRE works for each application. Basically, the JRE that will work would be the first in your PATH environment variable. You can change that, or the JAVA_HOME variable, or create specific cmd/bat files to launch the applications you desire, each with a different JRE in path.

For me the query that is working, if I want to compare with DrawDate for example is:

CAST(DrawDate AS DATE) = CAST (GETDATE() as DATE)

This is comparing results with today's date.

or the whole query:

SELECT TOP (1000) *
FROM test
where DrawName != 'NULL' and CAST(DrawDate AS DATE) = CAST (GETDATE() as DATE)
order by id desc

PHP 7 improved query.........

$sql = mysqli_query($conn, "SELECT * from users WHERE user_uid = '$uid'"); if (mysqli_num_rows($sql) > 0) { echo 'Username taken.'; }

First of all, I suggest to modify a bit your sql query:

 select * from shift 
 where shift.shiftid not in (select employeeshift.shiftid from employeeshift 
                             where employeeshift.empid = 57);

This query provides same functionality. If you want to get the same result with LINQ, you can try this code:

//Variable dc has DataContext type here
//Here we get list of ShiftIDs from employeeshift table
List<int> empShiftIds = dc.employeeshift.Where(p => p.EmpID = 57).Select(s => s.ShiftID).ToList();

//Here we get the list of our shifts
List<shift> shifts = dc.shift.Where(p => !empShiftIds.Contains(p.ShiftId)).ToList();

Using newInstance

public static MyDialogFragment newInstance(int num) {
    MyDialogFragment f = new MyDialogFragment();

    // Supply num input as an argument.
    Bundle args = new Bundle();
    args.putInt("num", num);
    f.setArguments(args);

    return f;
}

And get the Args like this

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mNum = getArguments().getInt("num");
    ...
}

See the full example here
http://developer.android.com/reference/android/app/DialogFragment.html

This is what I do for those situations:

I don't start the html element with class 'hide', but I put style="display: none".

This is because bootstrap jquery modifies the style attribute and not the classes to hide/unhide.

Example:

<button type="button" id="btn_cancel" class="btn default" style="display: none">Cancel</button>

or

<button type="button" id="btn_cancel" class="btn default display-hide">Cancel</button>

Later on, you can run all the following that will work:

$('#btn_cancel').toggle() // toggle between hide/unhide
$('#btn_cancel').hide()
$('#btn_cancel').show()

You can also uso the class of Twitter Bootstrap 'display-hide', which also works with the jQuery IU .toggle() method.

You need to use:

:%s/,/^M/g

To get the ^M character, press Ctrl + v followed by Enter.

In case a large chunk of data is deleted from a collection and the collection never uses the deleted space for new documents, this space needs to be returned to the operating system so that it can be used by other databases or collections. You will need to run a compact or repair operation in order to defragment the disk space and regain the usable free space.

Behavior of compaction process is dependent on MongoDB engine as follows

db.runCommand({compact: collection-name })

MMAPv1

Compaction operation defragments data files & indexes. However, it does not release space to the operating system. The operation is still useful to defragment and create more contiguous space for reuse by MongoDB. However, it is of no use though when the free disk space is very low.

An additional disk space up to 2GB is required during the compaction operation.

A database level lock is held during the compaction operation.

WiredTiger

The WiredTiger engine provides compression by default which consumes less disk space than MMAPv1.

The compact process releases the free space to the operating system. Minimal disk space is required to run the compact operation. WiredTiger also blocks all operations on the database as it needs database level lock.

For MMAPv1 engine, compact doest not return the space to operating system. You require to run repair operation to release the unused space.

db.runCommand({repairDatabase: 1})

@GET
@Path("/friends")
@Produces(MediaType.APPLICATION_JSON)
public String getFriends() {

    // here you can return any bean also it will automatically convert into json 
    return "{'friends': ['Michael', 'Tom', 'Daniel', 'John', 'Nick']}";
}

You could do it this way:

res.status(400).json(json_response);

This will set the HTTP status code to 400, it works even in express 4.

Twitter Bootstrap is incompatible with jQuery UI styles at the moment.

Just Cast date_field as date

SELECT * FROM `objects` 
WHERE (cast(date_field as date) BETWEEN '2010-09-29' AND 
'2010-01-30' )

The difference is that a var can be re-assigned to whereas a val cannot. The mutability, or otherwise of whatever is actually assigned, is a side issue:

import collection.immutable
import collection.mutable
var m = immutable.Set("London", "Paris")
m = immutable.Set("New York") //Reassignment - I have change the "value" at m.

Whereas:

val n = immutable.Set("London", "Paris")
n = immutable.Set("New York") //Will not compile as n is a val.

And hence:

val n = mutable.Set("London", "Paris")
n = mutable.Set("New York") //Will not compile, even though the type of n is mutable.

If you are building a data structure and all of its fields are vals, then that data structure is therefore immutable, as its state cannot change.

One classic difference between Synchronized block and Synchronized method is that Synchronized method locks the entire object. Synchronized block just locks the code within the block.

Synchronized method: Basically these 2 sync methods disable multithreading. So one thread completes the method1() and the another thread waits for the Thread1 completion.

class SyncExerciseWithSyncMethod {

public synchronized void method1() {
    try {
        System.out.println("In Method 1");
        Thread.sleep(5000);
    } catch (Exception e) {
        System.out.println("Catch of method 1");
    } finally {
        System.out.println("Finally of method 1");
    }

}

public synchronized void method2() {
    try {
        for (int i = 1; i < 10; i++) {
            System.out.println("Method 2 " + i);
            Thread.sleep(1000);
        }
    } catch (Exception e) {
        System.out.println("Catch of method 2");
    } finally {
        System.out.println("Finally of method 2");
    }
}

}

Output

In Method 1

Finally of method 1

Method 2 1

Method 2 2

Method 2 3

Method 2 4

Method 2 5

Method 2 6

Method 2 7

Method 2 8

Method 2 9

Finally of method 2

Synchronized block: Enables multiple threads to access the same object at same time [Enables multi-threading].

class SyncExerciseWithSyncBlock {

public Object lock1 = new Object();
public Object lock2 = new Object();

public void method1() {
    synchronized (lock1) {
        try {
            System.out.println("In Method 1");
            Thread.sleep(5000);
        } catch (Exception e) {
            System.out.println("Catch of method 1");
        } finally {
            System.out.println("Finally of method 1");
        }
    }

}

public void method2() {

    synchronized (lock2) {
        try {
            for (int i = 1; i < 10; i++) {
                System.out.println("Method 2 " + i);
                Thread.sleep(1000);
            }
        } catch (Exception e) {
            System.out.println("Catch of method 2");
        } finally {
            System.out.println("Finally of method 2");
        }
    }
}

}

Output

In Method 1

Method 2 1

Method 2 2

Method 2 3

Method 2 4

Method 2 5

Finally of method 1

Method 2 6

Method 2 7

Method 2 8

Method 2 9

Finally of method 2

Here's the answer that I found for my question:

urlList1.FocusedItem.Index

And I am getting selected item value by:

urlList1.Items(urlList1.FocusedItem.Index).SubItems(0).Text

use this for fixing issue with shadow box

filter: progid:DXImageTransform.Microsoft.dropShadow (OffX='2', OffY='2', Color='#F13434', Positive='true');

T-SQL doesn't support arrays that I'm aware of.

What's your table structure? You could probably design a query that does this instead:

select
month,
sum(sales)
from sales_table
group by month
order by month

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

To address specific scenario in question:

@Test
public void Test1() {

}

@Test (dependsOnMethods={"Test1"})
public void Test2() {

}

@Test (dependsOnMethods={"Test2"})
public void Test3() {

}

for this approach, you will need to add system.IO to your references by adding the next line of code below the other references near the top of the c# file(where the other using ****.** stand).

using System.IO;

this next code contains 2 methods of reading the text, the first will read single lines and stores them in a string variable, the second one reads the whole text and saves it in a string variable(including "\n" (enters))

both should be quite easy to understand and use.

    string pathToFile = "";//to save the location of the selected object
    private void openToolStripMenuItem_Click(object sender, EventArgs e)
    {
        OpenFileDialog theDialog = new OpenFileDialog();
        theDialog.Title = "Open Text File";
        theDialog.Filter = "TXT files|*.txt";
        theDialog.InitialDirectory = @"C:\";
        if (theDialog.ShowDialog() == DialogResult.OK)
        {
            MessageBox.Show(theDialog.FileName.ToString());
            pathToFile = theDialog.FileName;//doesn't need .tostring because .filename returns a string// saves the location of the selected object

        }

        if (File.Exists(pathToFile))// only executes if the file at pathtofile exists//you need to add the using System.IO reference at the top of te code to use this
        {
            //method1
            string firstLine = File.ReadAllLines(pathToFile).Skip(0).Take(1).First();//selects first line of the file
            string secondLine = File.ReadAllLines(pathToFile).Skip(1).Take(1).First();

            //method2
            string text = "";
            using(StreamReader sr =new StreamReader(pathToFile))
            {
                text = sr.ReadToEnd();//all text wil be saved in text enters are also saved
            }
        }
    }

To split the text you can use .Split(" ") and use a loop to put the name back into one string. if you don't want to use .Split() then you could also use foreach and ad an if statement to split it where needed.

to add the data to your class you can use the constructor to add the data like:

  public Employee(int EMPLOYEENUM, string NAME, string ADRESS, double WAGE, double HOURS)
        {
            EmployeeNum = EMPLOYEENUM;
            Name = NAME;
            Address = ADRESS;
            Wage = WAGE;
            Hours = HOURS;
        }

or you can add it using the set by typing .variablename after the name of the instance(if they are public and have a set this will work). to read the data you can use the get by typing .variablename after the name of the instance(if they are public and have a get this will work).

It would really help if you'd include the code that's not working (from the 'other' file), but I suspect you could do what you want with a healthy dose of the 'eval' function.

For example:

def run():
    print "this does nothing"

def chooser():
    return "run"

def main():
    '''works just like:
    run()'''
    eval(chooser())()

The chooser returns the name of the function to execute, eval then turns a string into actual code to be executed in-place, and the parentheses finish off the function call.

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

Simply throw Exception if input is invalid

Scanner sc=new Scanner(System.in);
try
{
  System.out.println("Please input an integer");
  //nextInt will throw InputMismatchException
  //if the next token does not match the Integer
  //regular expression, or is out of range
  int usrInput=sc.nextInt();
}
catch(InputMismatchException exception)
{
  //Print "This is not an integer"
  //when user put other than integer
  System.out.println("This is not an integer");
}

Java converts Integer to int and back automatically (unless you are still with Java 1.4).

public static int minIndex (ArrayList<Float> list) {
  return list.indexOf (Collections.min(list));
 }
System.out.println("Min = " + list.get(minIndex(list));

Here you go:

data = []
table = soup.find('table', attrs={'class':'lineItemsTable'})
table_body = table.find('tbody')

rows = table_body.find_all('tr')
for row in rows:
    cols = row.find_all('td')
    cols = [ele.text.strip() for ele in cols]
    data.append([ele for ele in cols if ele]) # Get rid of empty values

This gives you:

[ [u'1359711259', u'SRF', u'08/05/2013', u'5310 4 AVE', u'K', u'19', u'125.00', u'$'], 
  [u'7086775850', u'PAS', u'12/14/2013', u'3908 6th Ave', u'K', u'40', u'125.00', u'$'], 
  [u'7355010165', u'OMT', u'12/14/2013', u'3908 6th Ave', u'K', u'40', u'145.00', u'$'], 
  [u'4002488755', u'OMT', u'02/12/2014', u'NB 1ST AVE @ E 23RD ST', u'5', u'115.00', u'$'], 
  [u'7913806837', u'OMT', u'03/03/2014', u'5015 4th Ave', u'K', u'46', u'115.00', u'$'], 
  [u'5080015366', u'OMT', u'03/10/2014', u'EB 65TH ST @ 16TH AV E', u'7', u'50.00', u'$'], 
  [u'7208770670', u'OMT', u'04/08/2014', u'333 15th St', u'K', u'70', u'65.00', u'$'], 
  [u'$0.00\n\n\nPayment Amount:']
]

Couple of things to note:

• The last row in the output above, the Payment Amount is not a part of the table but that is how the table is laid out. You can filter it out by checking if the length of the list is less than 7.
• The last column of every row will have to be handled separately since it is an input text box.

You are using str methods on an open file object.

You can read the file as a list of lines by simply calling list() on the file object:

with open('goodlines.txt') as f:
    mylist = list(f)

This does include the newline characters. You can strip those in a list comprehension:

with open('goodlines.txt') as f:
    mylist = [line.rstrip('\n') for line in f]

If you go to Windows, Preferences then select General, Editors, Text editors, you can set colors on that property page (and there's a link for setting MORE colors - General, Appearance, Colors and fonts).

That's with an Eclipse 3.3 build anyway.

file_get_contents(php://input) - gets the raw POST data and you need to use this when you write APIs and need XML/JSON/... input that cannot be decoded to $_POST by PHP some example :

send by post JSON string

<input type="button" value= "click" onclick="fn()">
<script>
 function fn(){


    var js_obj = {plugin: 'jquery-json', version: 2.3};

    var encoded = JSON.stringify( js_obj );

var data= encoded


    $.ajax({
  type: "POST",
  url: '1.php',
  data: data,
  success: function(data){
    console.log(data);
  }

});

    }
</script>

1.php

//print_r($_POST); //empty!!! don't work ... 
var_dump( file_get_contents('php://input'));

You can use setdefault:

d = dict()
a = ['1', '2']
for i in a:
    for j in range(int(i), int(i) + 2): 
        d.setdefault(j, []).append(i)

print d  # prints {1: ['1'], 2: ['1', '2'], 3: ['2']}

The rather oddly-named setdefault function says "Get the value with this key, or if that key isn't there, add this value and then return it."

As others have rightly pointed out, defaultdict is a better and more modern choice. setdefault is still useful in older versions of Python (prior to 2.5).

This is possible in KeyDB which is a Fork of Redis. Because it's a Fork its fully compatible with Redis and works as a drop in replacement.

Just use the EXPIREMEMBER command. It works with sets, hashes, and sorted sets.

EXPIREMEMBER keyname subkey [time]

You can also use TTL and PTTL to see the expiration

TTL keyname subkey

More documentation is available here: https://docs.keydb.dev/docs/commands/#expiremember

Something like this?

public static T ConvertValue<T>(string value)
{
    return (T)Convert.ChangeType(value, typeof(T));
}

You can then use it like this:

int val = ConvertValue<int>("42");

Edit:

You can even do this more generic and not rely on a string parameter provided the type U implements IConvertible - this means you have to specify two type parameters though:

public static T ConvertValue<T,U>(U value) where U : IConvertible
{
    return (T)Convert.ChangeType(value, typeof(T));

I considered catching the InvalidCastException exception that might be raised by Convert.ChangeType() - but what would you return in this case? default(T)? It seems more appropriate having the caller deal with the exception.

Super late to the party but if someone finds this out.

You can call IConfiguration from Microsoft.Extensions.Configuration;

public static IConfiguration Configuration { get; }
public static string MyAwesomeString = Configuration.GetSection("appSettings")["MyAwesomeString"].ToString();

I'm no expert in map-reading / navigation and so on but surely 'directions' are absolute and not relative or in reality, they are relative to N or S which themselves are fixed/absolute.

Example: Suppose an imaginary line drawn between you and your destination corresponds with 'absolute' SE (a bearing of 135 degrees relative to magnetic N). Now suppose your phone is pointing NW - if you draw an imaginary line from an imaginary object on the horizon to your destination, it will pass through your location and have an angle of 180 degrees. Now 180 degrees in the sense of a compass actually refers to S but the destination is not 'due S' of the imaginary object your phone is pointing at and, moreover, if you travelled to that imaginary point, your destination would still be SE of where you moved to.

In reality, the 180 degree line actually tells you the destination is 'behind you' relative to the way the phone (and presumably you) are pointing.

Having said that, however, if calculating the angle of a line from the imaginary point to your destination (passing through your location) in order to draw a pointer towards your destination is what you want...simply subtract the (absolute) bearing of the destination from the absolute bearing of the imaginary object and ignore a negation (if present). e.g., NW - SE is 315 - 135 = 180 so draw the pointer to point at the bottom of the screen indicating 'behind you'.

EDIT: I got the Maths slightly wrong...subtract the smaller of the bearings from the larger then subtract the result from 360 to get the angle in which to draw the pointer on the screen.

VAL1 and VAL2 need to be dimmed as integer, not as string, to be used as an argument for Cells, which takes integers, not strings, as arguments.

Dim val1 As Integer, val2 As Integer, i As Integer

For i = 1 To 333

  Sheets("Feuil2").Activate
  ActiveSheet.Cells(i, 1).Select

    val1 = Cells(i, 1).Value
    val2 = Cells(i, 2).Value

Sheets("Classeur2.csv").Select
Cells(val1, val2).Select

ActiveCell.FormulaR1C1 = "1"

Next i

javascript has the sort function which can take another function as parameter - that second function is used to compare two elements.

Example:

cars = [

    {
        name: "Honda",
        speed: 80
    },

    {
        name: "BMW",
        speed: 180
    },

    {
        name: "Trabi",
        speed: 40
    },

    {
        name: "Ferrari",
        speed: 200
    }
]


cars.sort(function(a, b) { 
    return a.speed - b.speed;
})

for(var i in cars)
    document.writeln(cars[i].name) // Trabi Honda BMW Ferrari 

ok, from your comment i see that you're using the word 'sort' in a wrong sense. In programming "sort" means "put things in a certain order", not "arrange things in groups". The latter is much simpler - this is just how you "sort" things in the real world

• make two empty arrays ("boxes")
• for each object in your list, check if it matches the criteria
• if yes, put it in the first "box"
• if no, put it in the second "box"

Actually there are 3 places where gradle.properties can be placed:

1. Under gradle user home directory defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle
2. The sub-project directory (myProject2 in your case)
3. The root project directory (under myProject)

Gradle looks for gradle.properties in all these places while giving precedence to properties definition based on the order above. So for example, for a property defined in gradle user home directory (#1) and the sub-project (#2) its value will be taken from gradle user home directory (#1).

You can find more details about it in gradle documentation here.

Looking in the headers sent...
res.send uses content-type:text/html
res.json uses content-type:application/json

edit: send actually changes what is sent based on what it's given, so strings are sent as text/html, but it you pass it an object it emits application/json.

compiler arranges that static variable initialization does not happen each time the function is entered

To solve a similar problem, I'm using groupby:

print(f"Distinct entries: {len(df.groupby(['col1', 'col2']))}")

Whether that's appropriate will depend on what you want to do with the result, though (in my case, I just wanted the equivalent of COUNT DISTINCT as shown).

In Ansible >1.4 you can actually specify a remote user at the task level which should allow you to login as that user and execute that command without resorting to sudo. If you can't login as that user then the sudo_user solution will work too.

You may go with Plotly library. It can render interactive 3D plots directly in Jupyter Notebooks.

To do so you first need to install Plotly by running:

pip install plotly

You might also want to upgrade the library by running:

pip install plotly --upgrade

After that in you Jupyter Notebook you may write something like:

# Import dependencies
import plotly
import plotly.graph_objs as go

# Configure Plotly to be rendered inline in the notebook.
plotly.offline.init_notebook_mode()

# Configure the trace.
trace = go.Scatter3d(
    x=[1, 2, 3],  # <-- Put your data instead
    y=[4, 5, 6],  # <-- Put your data instead
    z=[7, 8, 9],  # <-- Put your data instead
    mode='markers',
    marker={
        'size': 10,
        'opacity': 0.8,
    }
)

# Configure the layout.
layout = go.Layout(
    margin={'l': 0, 'r': 0, 'b': 0, 't': 0}
)

data = [trace]

plot_figure = go.Figure(data=data, layout=layout)

# Render the plot.
plotly.offline.iplot(plot_figure)

As a result the following chart will be plotted for you in Jupyter Notebook and you'll be able to interact with it. Of course you will need to provide your specific data instead of suggeseted one.

I believe commenting out display_errors in php.ini won't work because the default is On. You must set it to 'Off' instead.

Don't forget to restart Apache to apply configuration changes.

Also note that while you can set display_errors at runtime, changing it here does not affect FATAL errors.

As noted by others, ideally during development you should run with error_reporting at the highest level possible and display_errors enabled. While annoying when you first start out, these errors, warnings, notices and strict coding advice all add up and enable you to becoem a better coder.

I got the same error message for two separate reasons, so you can add them to your debugging checklist:

Context: Xcode 6.4, iOS:8.4. I was adding a toolbar with custom UIBarButtons to load with the UIKeyboardTypeNumberPad (Swift: UIKeyboardType.numberPad) , namely "Done" and "+/-". I had this problem when:

1. My UIToolbar was declared as a property, but I had forgotten to explicitly alloc/init it.

2. I had left off the last line, [myCustomToolbar sizeToFit];, which sounds like it's the same family as Holden's answer (my code here: https://stackoverflow.com/a/32016397/4898050).

Good luck

Hopefully this is helpful to anyone coming looking for a universal/isomorphic solution, since the checksum issue is what led me here in the first place.

As said above, I've created a simple utility to sequentially create a new id. Since the IDs keep incrementing on the server, and start over from 0 in the client, I decided to reset the increment each the SSR starts.

// utility to generate ids
let current = 0

export default function generateId (prefix) {
  return `${prefix || 'id'}-${current++}`
}

export function resetIdCounter () { current = 0 }

And then in the root component's constructor or componentWillMount, call the reset. This essentially resets the JS scope for the server in each server render. In the client it doesn't (and shouldn't) have any effect.

Just revisiting this as it's something I just faced and there is some incorrect stuff in the answers (though it's mentioned in the comments).

First thing though. The original questions asks how to tell if a PowerShell module is installed. We need to talk about the word installed! You don't install PowerShell modules (not in the traditional way you install software anyway).

PowerShell modules are either available (i.e. they are on the PowerShell module path), or they are imported (they are imported into your session and you can call the functions contained). This is how to check your module path, in case you want to know where to store a module:

$env:psmodulepath

I'd argue that it's becoming common to use C:\Program Files\WindowsPowerShell\Modules; more often due to it being available to all users, but if you want to lock down your modules to your own session, include them in your profile. C:\Users\%username%\Documents\WindowsPowerShell\Modules;

Alright, back to the two states.

Is the module available (using available to mean installed in the original question)?

Get-Module -Listavailable -Name <modulename>

This tells you if a module is available for import.

Is the module imported? (I'm using this as the answer for the word 'exists' in the original question).

Get-module -Name <modulename>

This will either return an empty load of nothing if the module is not imported, or a one line description of the module if it is. As ever on Stack Overflow, try the commands above on your own modules.

Try this...

function nationList($limit=null, $start=null) {
    if ($this->session->userdata('language') == "it") {
        $this->db->select('nation.id, nation.name_it as name');
    }

    if ($this->session->userdata('language') == "en") {
        $this->db->select('nation.id, nation.name_en as name');
    }

    $this->db->from('nation');
    $this->db->order_by("name", "asc");

    if ($limit != '' && $start != '') {
       $this->db->limit($limit, $start);
    }
    $query  = $this->db->get();

    $nation = array();
    foreach ($query->result() as $row) {
        array_push($nation, $row);
    }

    return $nation;     
}

try this

$("label").html(your value); or $("label").text(your value);

Label1.Text = dt.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");

will output:

07 Mai 2009 | 08:16 | 13 | +02:00 | +02 | +2

I'm in Denmark, my Offset from GMT is +2 hours, witch is correct.

if you need to get the CLIENT Offset, I recommend that you check a little trick that I did. The Page is in a Server in UK where GMT is +00:00 and, as you can see you will get your local GMT Offset.

Regarding you comment, I did:

DateTime dt1 = DateTime.Now;
DateTime dt2 = dt1.ToUniversalTime();

Label1.Text = dt1.ToString("dd MMM yyyy | hh:mm | ff | zzz | zz | z");
Label2.Text = dt2.ToString("dd MMM yyyy | hh:mm | FF | ZZZ | ZZ | Z");

and I get this:

07 Mai 2009 | 08:24 | 14 | +02:00 | +02 | +2
07 Mai 2009 | 06:24 | 14 | ZZZ | ZZ | Z 

I get no Exception, just ... it does nothing with capital Z :(

I'm sorry, but am I missing something?

Reading carefully the MSDN on Custom Date and Time Format Strings

there is no support for uppercase 'Z'.

As you say, REST is good enough for banks so should be good enough for you.

There are two main aspects to security: 1) encryption and 2) identity.

Transmitting in SSL/HTTPS provides encryption over the wire. But you'll also need to make sure that both servers can confirm that they know who they are speaking to. This can be via SSL client certificates, shares secrets, etc.

I'm sure one could make the case that SOAP is "more secure" but probably not in any significant way. The nude motorcyclist analogy is cute but if accurate would imply that the whole internet is insecure.

SELECT * FROM a WHERE a.group_id IN 
(SELECT group_id FROM b WHERE b.user_id!=$_SESSION{'[user_id']} AND b.group_id = a.group_id)
WHERE a.keyword LIKE '%".$keyword."%';

You have a problem with a png file maybe, look here :

Nested classes are very useful for implementing internal details that should not be exposed. If you use Reflector to check classes like Dictionary<Tkey,TValue> or Hashtable you'll find some examples.

Update Nov. 2015: As per Hans Z. below - this is now indeed defined as part of RFC 7662.

Original Answer: The OAuth 2.0 spec (RFC 6749) doesn't clearly define the interaction between a Resource Server (RS) and Authorization Server (AS) for access token (AT) validation. It really depends on the AS's token format/strategy - some tokens are self-contained (like JSON Web Tokens) while others may be similar to a session cookie in that they just reference information held server side back at the AS.

There has been some discussion in the OAuth Working Group about creating a standard way for an RS to communicate with the AS for AT validation. My company (Ping Identity) has come up with one such approach for our commercial OAuth AS (PingFederate): https://support.pingidentity.com/s/document-item?bundleId=pingfederate-93&topicId=lzn1564003025072.html#lzn1564003025072__section_N10578_N1002A_N10001. It uses REST based interaction for this that is very complementary to OAuth 2.0.

A functional approach

const capitalize = ([s, ...tring]) =>
  [s.toUpperCase(), ...tring]
    .join('');

Then you could

const titleCase = str => 
  str
    .split(' ')
    .map(capitalize)
    .join(' ')

Have a look at Knockout-Validation which cleanly setups and uses what's described in the knockout documentation. Under: Live Example 1: Forcing input to be numeric

You can see it live in Fiddle

UPDATE: the fiddle has been updated to use the latest KO 2.0.3 and ko.validation 1.0.2 using the cloudfare CDN urls

To setup ko.validation:

ko.validation.rules.pattern.message = 'Invalid.';

ko.validation.configure({
    registerExtenders: true,
    messagesOnModified: true,
    insertMessages: true,
    parseInputAttributes: true,
    messageTemplate: null
});

To setup validation rules, use extenders. For instance:

var viewModel = {
    firstName: ko.observable().extend({ minLength: 2, maxLength: 10 }),
    lastName: ko.observable().extend({ required: true }),
    emailAddress: ko.observable().extend({  // custom message
        required: { message: 'Please supply your email address.' }
    })
};

Just add the following:

#define __USE_C99_MATH

#include <stdbool.h>

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

You can't compare strings with == in C. For C, strings are just (zero-terminated) arrays, so you need to use string functions to compare them. See the man page for strcmp() and strncmp().

If you want to compare a character you need to compare to a character, not a string. "a" is the string a, which occupies two bytes (the a and the terminating null byte), while the character a is represented by 'a' in C.

Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

UPD 19.03.2019 Here is a version for browser on GitHub.

Thew problem is because of spaces in the titles(Headers). Remove spaces in all headers and it works fine.

Styles

 @media print {

       .no-print{
               display : none !important;
                }
              }

Jquery

    function printInvoice()
 {
     printDiv = "#printDiv"; // id of the div you want to print
     $("*").addClass("no-print");
     $(printDiv+" *").removeClass("no-print");
     $(printDiv).removeClass("no-print");

     parent =  $(printDiv).parent();
     while($(parent).length)
     {
         $(parent).removeClass("no-print");
         parent =  $(parent).parent();
     }
     window.print();

 }

Print Button Html

<input type="button" onclick="printInvoice();" value="Print">

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

Try

CREATE TABLE foo LIKE bar;

so the keys and indexes are copied over as, well.

Documentation

Note that the link you provided does is not an HTML page, but rather a JSON document. The formatting is done by the browser.

You have to decide if:

1. You want to show the raw JSON (not an HTML page), as in your example
2. Show an HTML page with formatted JSON

If you want 1., just tell your application to render a response body with the JSON, set the MIME type (application/json), etc. In this case, formatting is dealt by the browser (and/or browser plugins)

If 2., it's a matter of rendering a simple minimal HTML page with the JSON where you can highlight it in several ways:

• server-side, depending on your stack. There are solutions for almost every language
• client-side with Javascript highlight libraries.

If you give more details about your stack, it's easier to provide examples or resources.

EDIT: For client side JS highlighting you can try higlight.js, for instance.

The solution to this is actually easier than I thought. You can simply add in your custom adapter's getView() method a setOnClickListener() for the buttons you're using.

Any data associated with the button has to be added with myButton.setTag() in the getView() and can be accessed in the onClickListener via view.getTag()

I posted a detailed solution on my blog as a tutorial.

I believe you can only add variables to the Watch window while the debugger is stopped on a breakpoint. If you set a breakpoint on a step, you should be able to enter variables into the Watch window when the breakpoint is hit. You can select the first empty row in the Watch window and enter the variable name (you may or may not get some Intellisense there, I can't remember how well that works.)

I am not clear exactly what your situation requires but the following may get you started. The key here is using ThisWorkbook.Path to get a relative file path:

Sub SaveToRelativePath()
    Dim relativePath As String
    relativePath = ThisWorkbook.Path & Application.PathSeparator & ActiveWorkbook.Name
    ActiveWorkbook.SaveAs Filename:=relativePath
End Sub

Another alternative is to use Pandas dataframe as it guarantees the order and the index locations of the items in a dict-like structure.

In case of circle all you need is one div, but in case of hollow square you need to have 2 divs. The divs are having a display of inline-block which you can change accordingly. Live Codepen link: Click Me

In case of circle all you need to change is the border properties and the dimensions(width and height) of circle. If you want to change color just change the border color of hollow-circle.

In case of the square background-color property needs to be changed depending upon the background of page or the element upon which you want to place the hollow-square. Always keep the inner-circle dimension small as compared to the hollow-square. If you want to change color just change the background-color of hollow-square. The inner-circle is centered upon the hollow-square using the position, top, left, transform properties just don't mess with them.

Code is as follows:

/* CSS Code */_x000D_
_x000D_

Today, I also got stuck in same issue, and resolve the issue I have added a user control and
on this control I use this code

<div class="divformTagEx">

</div>

<asp:Literal runat="server" ID="litFormTag" Visible="false">
'<div> <form  style="margin-bottom: 3;" action="http://login.php" method="post" name="testformtag"></form> </div>'</asp:Literal>

and on PreRenderComplete event of the page call this method

private void InitializeJavaScript()
{
        var script = new StringBuilder();
        script.Append("$(document).ready(function () {");
        script.Append("$('.divformTagEx').append( ");
        script.Append(litFormTag.Text);
        script.Append(" )");
        script.Append(" });");
        ScriptManager.RegisterStartupScript(this, GetType(), "nestedFormTagEx", script.ToString(), true);
    }

I believe this will help.

It could be due to the architecture of your OS. Is your OS 64 Bit and have you installed 64 bit version of Python? It may help to install both 32 bit version Python 3.1 and Pygame, which is available officially only in 32 bit and you won't face this problem.

I see that 64 bit pygame is maintained here, you might also want to try uninstalling Pygame only and install the 64 bit version on your existing python3.1, if not choose go for both 32-bit version.

Truth be told there are many, many resources explaining how to do this already out on the web:

Git: how to reverse-merge a commit?

Git: how to reverse-merge a commit?

Undoing Merges, from Git's blog (retrieved from archive.org's Wayback Machine)

So I guess I'll just summarize some of these:

1. git revert <merge commit hash>
   This creates an extra "revert" commit saying you undid a merge

2. git reset --hard <commit hash *before* the merge>
   This reset history to before you did the merge. If you have commits after the merge you will need to cherry-pick them on to afterwards.

But honestly this guide here is better than anything I can explain, with diagrams! :)

If you run pub build --mode=debug the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug is used.

Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline

@Greg:

Why not do your example like this:

void foo()
{
    if (doA())
    {    
        if (doB())
        {
          if (!doC())
          {
             UndoA();
             UndoB();
          }
        }
        else
        {
          UndoA();
        }
    }
    return;
}

The git rev-parse solution proposed by @Andy works fine if the date you're interested is the commit's date. If however you want to checkout based on the author's date, rev-parse won't work, because it doesn't offer an option to use that date for selecting the commits. Instead, you can use the following.

git checkout $(
  git log --reverse --author-date-order --pretty=format:'%ai %H' master |
  awk '{hash = $4} $1 >= "2016-04-12" {print hash; exit 0 }
)

(If you also want to specify the time use $1 >= "2016-04-12" && $2 >= "11:37" in the awk predicate.)

You can use subqueries in anonymous function like this:

 $results = User::where('this', '=', 1)
            ->where('that', '=', 1)
            ->where(function($query) {
                /** @var $query Illuminate\Database\Query\Builder  */
                return $query->where('this_too', 'LIKE', '%fake%')
                    ->orWhere('that_too', '=', 1);
            })
            ->get();

The good news is a transaction in SQL Server can span multiple batches (each exec is treated as a separate batch.)

You can wrap your EXEC statements in a BEGIN TRANSACTION and COMMIT but you'll need to go a step further and rollback if any errors occur.

Ideally you'd want something like this:

BEGIN TRY
    BEGIN TRANSACTION 
        exec( @sqlHeader)
        exec(@sqlTotals)
        exec(@sqlLine)
    COMMIT
END TRY
BEGIN CATCH

    IF @@TRANCOUNT > 0
        ROLLBACK
END CATCH

The BEGIN TRANSACTION and COMMIT I believe you are already familiar with. The BEGIN TRY and BEGIN CATCH blocks are basically there to catch and handle any errors that occur. If any of your EXEC statements raise an error, the code execution will jump to the CATCH block.

Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

It tells the browser to read the css file as UTF-8. This is handy if your CSS contains unicode characters and not only ASCII.

Using it in the meta tag is fine, but only for pages that include that meta tag.

Read about the rules for character set resolution of CSS files at the w3c spec for CSS 2.

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!

IIS express configuration is managed by applicationhost.config.
You can find it in

Users\<username>\Documents\IISExpress\config folder.

Inside you can find the sites section that hold a section for each IIS Express configured site.

Add (or modify) a site section like this:

<site name="WebSiteWithVirtualDirectory" id="20">
   <application path="/" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="c:\temp\website1" />
   </application>
   <application path="/OffSiteStuff" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="d:\temp\SubFolderApp" />
   </application>
    <bindings>
      <binding protocol="http" bindingInformation="*:1132:localhost" />
   </bindings>
</site>

Practically you need to add a new application tag in your site for each virtual directory. You get a lot of flexibility because you can set different configuration for the virtual directory (for example a different .Net Framework version)

EDIT Thanks to Fevzi Apaydin to point to a more elegant solution.

You can achieve same result by adding one or more virtualDirectory tag to the Application tag:

<site name="WebSiteWithVirtualDirectory" id="20">
   <application path="/" applicationPool="Clr4IntegratedAppPool">
     <virtualDirectory path="/" physicalPath="c:\temp\website1" />
     <virtualDirectory path="/OffSiteStuff" physicalPath="d:\temp\SubFolderApp" />
   </application>
    <bindings>
      <binding protocol="http" bindingInformation="*:1132:localhost" />
   </bindings>
</site>

• Application tag for a Site
• Virtual Directory tag

Another way of doing it. This approach can be useful for changing the text to 2 different colors, just by adding 2 spans.

Label1.Text = "String with original color" + "<b><span style=""color:red;"">" + "Your String Here" + "</span></b>";

With .NET Framework 4.7 one can use decomposition

var fruits = new Dictionary<string, int>();
...
foreach (var (fruit, number) in fruits)
{
    Console.WriteLine(fruit + ": " + number);
}

To make this code work on lower C# versions, add System.ValueTuple NuGet package and write somewhere

public static class MyExtensions
{
    public static void Deconstruct<T1, T2>(this KeyValuePair<T1, T2> tuple,
        out T1 key, out T2 value)
    {
        key = tuple.Key;
        value = tuple.Value;
    }
}

In your my.ini, write this:

[mysqld]
sql_mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

depend on your version. Or:

[mysqld]
sql_mode = ""

or simply remove this: ONLY_FULL_GROUP_BY

Remove "SSLv2ClientHello" from the enabled protocols on the client SSLSocket or HttpsURLConnection.

The accepted answer didn't work for me for two reasons:

1. I had BackColor set so setting AutoSize = false and Dock = Fill causes the background color to fill the whole form
2. I couldn't have AutoSize set to false anyway because my label text was dynamic

Instead, I simply used the form's width and the width of the label to calculate the left offset:

MyLabel.Left = (this.Width - MyLabel.Width) / 2;

Try this;

@media print{ @page { margin-top: 30px; margin-bottom: 30px;}}

if you're happy using it as a background image and CSS3 then background-size: cover; would do the trick

i=-62 . If you want to convert it to a unsigned representation. It would be 4294967234 for a 32 bit integer. A simple way would be to

num=-62
unsigned int n;
n = num
cout<<n;

4294967234

Microsoft® SQL Server™ 2000 uses these SQL-92 keywords for outer joins specified in a FROM clause:

• LEFT OUTER JOIN or LEFT JOIN

• RIGHT OUTER JOIN or RIGHT JOIN

• FULL OUTER JOIN or FULL JOIN

From MSDN

The full outer join or full join returns all rows from both tables, matching up the rows wherever a match can be made and placing NULLs in the places where no matching row exists.

I know this is very late answer but works very well...

var obj = {
a:"a",
b:"b"
}

Object.entries(obj).map(([key, val])=>`${key}=${val}`).join("&");

note: object.entries will return key,values pairs

output from above line will be a=a&b=b

Hope its helps someone.

Happy Coding...

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

Use references all the time and pointers only when you have to refer to NULL which reference cannot refer.

See this FAQ : http://www.parashift.com/c++-faq-lite/references.html#faq-8.6

For length including white-space:

$("#id").val().length

For length without white-space:

$("#id").val().replace(/ /g,'').length

For removing only beginning and trailing white-space:

$.trim($("#test").val()).length

For example, the string " t e s t " would evaluate as:

//" t e s t "
$("#id").val(); 

//Example 1
$("#id").val().length; //Returns 9
//Example 2
$("#id").val().replace(/ /g,'').length; //Returns 4
//Example 3
$.trim($("#test").val()).length; //Returns 7

Here is a demo using all of them.

Two different options to add item to an array without mutation

case ADD_ITEM :
    return { 
        ...state,
        arr: [...state.arr, action.newItem]
    }

OR

case ADD_ITEM :
    return { 
        ...state,
        arr: state.arr.concat(action.newItem)
    }

Using Lambda:

    new AlertDialog.Builder(this).setMessage(getString(R.string.exit_msg))
        .setTitle(getString(R.string.info))
        .setPositiveButton(getString(R.string.yes), (arg0, arg1) -> {
            moveTaskToBack(true);
            finish();
        })
        .setNegativeButton(getString(R.string.no), (arg0, arg1) -> {
        })
        .show();

You also need to set level language to support java 8 in your gradle.build:

compileOptions {
       targetCompatibility 1.8
       sourceCompatibility 1.8
}

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

To answer your direct question, it is:

Range("A1").NumberFormat = "@"

Or

Cells(1,1).NumberFormat = "@"

However, I suggest making changing the format to what you actually want displayed. This allows you to retain the data type in the cell and easily use cell formulas to manipulate the data.

Here's a quick sample:

//Create process
System.Diagnostics.Process pProcess = new System.Diagnostics.Process();

//strCommand is path and file name of command to run
pProcess.StartInfo.FileName = strCommand;

//strCommandParameters are parameters to pass to program
pProcess.StartInfo.Arguments = strCommandParameters;

pProcess.StartInfo.UseShellExecute = false;

//Set output of program to be written to process output stream
pProcess.StartInfo.RedirectStandardOutput = true;   

//Optional
pProcess.StartInfo.WorkingDirectory = strWorkingDirectory;

//Start the process
pProcess.Start();

//Get program output
string strOutput = pProcess.StandardOutput.ReadToEnd();

//Wait for process to finish
pProcess.WaitForExit();

In python3.7.7, the definition of json.load is as below according to cpython source code:

def load(fp, *, cls=None, object_hook=None, parse_float=None,
        parse_int=None, parse_constant=None, object_pairs_hook=None, **kw):

    return loads(fp.read(),
        cls=cls, object_hook=object_hook,
        parse_float=parse_float, parse_int=parse_int,
        parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw)

json.load actually calls json.loads and use fp.read() as the first argument.

So if your code is:

with open (file) as fp:
    s = fp.read()
    json.loads(s)

It's the same to do this:

with open (file) as fp:
    json.load(fp)

But if you need to specify the bytes reading from the file as like fp.read(10) or the string/bytes you want to deserialize is not from file, you should use json.loads()

As for json.loads(), it not only deserialize string but also bytes. If s is bytes or bytearray, it will be decoded to string first. You can also find it in the source code.

def loads(s, *, encoding=None, cls=None, object_hook=None, parse_float=None,
        parse_int=None, parse_constant=None, object_pairs_hook=None, **kw):
    """Deserialize ``s`` (a ``str``, ``bytes`` or ``bytearray`` instance
    containing a JSON document) to a Python object.

    ...

    """
    if isinstance(s, str):
        if s.startswith('\ufeff'):
            raise JSONDecodeError("Unexpected UTF-8 BOM (decode using utf-8-sig)",
                                  s, 0)
    else:
        if not isinstance(s, (bytes, bytearray)):
            raise TypeError(f'the JSON object must be str, bytes or bytearray, '
                            f'not {s.__class__.__name__}')
        s = s.decode(detect_encoding(s), 'surrogatepass')

These multiplications to 1000 for milliseconds may be decent for solving or making some prerequisite acceptable. It could be used to fill a gap in your database which doesn't really ever use it. Although, for real situations which require precise timing it would ultimately fail. I wouldn't suggest anyone use this method for mission-critical operations which require actions, or processing at specific timings.

For example: round-trip pings being 30-80ms in the USA... You couldn't just round that up and use it efficiently.

My own example requires tasks at every second which means if I rounded up after the first tasks responded I would still incur the processing time multiplied every main loop cycle. This ended up being a total function call every 60 seconds. that's ~1440 a day.. not too accurate.

Just a thought for people looking for more accurate reasoning beyond solving a database gap which never really uses it.

Span is completely non-semantic. It has no meaning, and serves merely as an element for cosmetic effects.

Paragraphs have semantic meaning - they tell a machine (like a browser or a screen reader) that the content they encapsulate is a block of text, and has the same meaning as a paragraph of text in a book.

If your're looking to set the current datetime for a dateTime column (like i was when I googled), use this way

$table->dateTime('signed_when')->useCurrent();

For others unexpectedly getting the Window element, a common pitfall:

<a href="javascript:myfunction(this)">click here</a>

which actually scopes this to the Window object. Instead:

<a href="javascript:nop()" onclick="myfunction(this)">click here</a>

passes the a object as expected. (nop() is just any empty function.)

Once you pass the assembly instance back to the caller domain, the caller domain will try to load it! This is why you get the exception. This happens in your last line of code:

domain.Load(AssemblyName.GetAssemblyName(path));

Thus, whatever you want to do with the assembly, should be done in a proxy class - a class which inherit MarshalByRefObject.

Take in count that the caller domain and the new created domain should both have access to the proxy class assembly. If your issue is not too complicated, consider leaving the ApplicationBase folder unchanged, so it will be same as the caller domain folder (the new domain will only load Assemblies it needs).

In simple code:

public void DoStuffInOtherDomain()
{
    const string assemblyPath = @"[AsmPath]";
    var newDomain = AppDomain.CreateDomain("newDomain");
    var asmLoaderProxy = (ProxyDomain)newDomain.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, typeof(ProxyDomain).FullName);

    asmLoaderProxy.GetAssembly(assemblyPath);
}

class ProxyDomain : MarshalByRefObject
{
    public void GetAssembly(string AssemblyPath)
    {
        try
        {
            Assembly.LoadFrom(AssemblyPath);
            //If you want to do anything further to that assembly, you need to do it here.
        }
        catch (Exception ex)
        {
            throw new InvalidOperationException(ex.Message, ex);
        }
    }
}

If you do need to load the assemblies from a folder which is different than you current app domain folder, create the new app domain with specific dlls search path folder.

For example, the app domain creation line from the above code should be replaced with:

var dllsSearchPath = @"[dlls search path for new app domain]";
AppDomain newDomain = AppDomain.CreateDomain("newDomain", new Evidence(), dllsSearchPath, "", true);

This way, all the dlls will automaically be resolved from dllsSearchPath.

I have a single-page app in our company intranet where certain date fields need to be "blocked" under certain circumstances. Those date fields have a datepicker binding.

Making the fields read-only wasn't enough to block the fields, as datepicker still triggers when the field receives focus.

Disabling the field (or disabling datepicker) have side effects with serialize() or serializeArray().

One of the options was to unbind datepicker from those fields and making them "normal" fields. But one easiest solution is to make the field (or fields) read-only and to avoid datepicker from acting when receive focus.

$('#datefield').attr('readonly',true).datepicker("option", "showOn", "off");

If there is any error at all in the PATH windows will silently disregard it. Things like having %PATH% or spaces between items in your path will break it. Be warned

Or:

SELECT SUM(foo), DATE(mydate) mydate FROM a_table GROUP BY mydate;

More efficient (I think.) Because you don't have to cast mydate twice per row.

You need to do some escaping I think.

find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} \-sameq {}.mp3 \&\& rm {}\;

You can use VARRAY for a fixed-size array:

declare
   type array_t is varray(3) of varchar2(10);
   array array_t := array_t('Matt', 'Joanne', 'Robert');
begin
   for i in 1..array.count loop
       dbms_output.put_line(array(i));
   end loop;
end;

Or TABLE for an unbounded array:

...
   type array_t is table of varchar2(10);
...

The word "table" here has nothing to do with database tables, confusingly. Both methods create in-memory arrays.

With either of these you need to both initialise and extend the collection before adding elements:

declare
   type array_t is varray(3) of varchar2(10);
   array array_t := array_t(); -- Initialise it
begin
   for i in 1..3 loop
      array.extend(); -- Extend it
      array(i) := 'x';
   end loop;
end;

The first index is 1 not 0.

I'm using react-native CLI and I just restart rn-cli, ctrl+c to stop the process then npx react-native start

You want to make the format/style explicit and don't rely on interpretation based on local settings (which may vary among your clients infrastructure).

DECLARE @Test AS DATETIME
SET @Test = CONVERT(DATETIME, '2011-02-15 00:00:00', 120) -- yyyy-MM-dd hh:mm:ss
SELECT @Test

While there is a plethora of styles, you may want to remember few

• 126 (ISO 8601): yyyy-MM-ddThh:mm:ss(.mmm)
• 120: yyyy-MM-dd hh:mm:ss
• 112: yyyyMMdd

Note that the T in the ISO 8601 is actually the letter T and not a variable.

This worked for SQL Server 2005, 2008, and 2012. I found that the sys.identity_columns did not contain all my tables with identity columns.

SELECT a.name AS TableName, b.name AS IdentityColumn
FROM sys.sysobjects a 
JOIN sys.syscolumns b 
ON a.id = b.id
WHERE is_identity = 1
ORDER BY name;

Looking at the documentation page the status column can also be utilized. Also you can add the four part identifier and it will work across different servers.

SELECT a.name AS TableName, b.name AS IdentityColumn
FROM [YOUR_SERVER_NAME].[YOUR_DB_NAME].sys.sysobjects a 
JOIN [YOUR_SERVER_NAME].[YOUR_DB_NAME].sys.syscolumns b 
ON a.id = b.id
WHERE is_identity = 1
ORDER BY name;

dat <- dat[-1, ] worked but it killed my dataframe, changing it into another type. Had to instead use dat <- data.frame(dat[-1, ]) but this is possibly a special case as this dataframe initially had only one column.

Use the Resource like

ResourceBundle rb = ResourceBundle.getBundle("com//sudeep//internationalization//MyApp",locale);
or
ResourceBundle rb = ResourceBundle.getBundle("com.sudeep.internationalization.MyApp",locale);

Just give the qualified path .. Its working for me!!!

I added this helper method to handle my POST requests that return an object I care about.

For REST purists, I know, POSTs should not return anything besides a status. However, I had a large collection of ids that was too big for a query string parameter.

Helper Method:

    public TResponse Post<TResponse>(string relativeUri, object postBody) where TResponse : new()
    {
        //Note: Ideally the RestClient isn't created for each request. 
        var restClient = new RestClient("http://localhost:999");

        var restRequest = new RestRequest(relativeUri, Method.POST)
        {
            RequestFormat = DataFormat.Json
        };

        restRequest.AddBody(postBody);

        var result = restClient.Post<TResponse>(restRequest);

        if (!result.IsSuccessful)
        {
            throw new HttpException($"Item not found: {result.ErrorMessage}");
        }

        return result.Data;
    }

Usage:

    public List<WhateverReturnType> GetFromApi()
    {
        var idsForLookup = new List<int> {1, 2, 3, 4, 5};

        var relativeUri = "/api/idLookup";

        var restResponse = Post<List<WhateverReturnType>>(relativeUri, idsForLookup);

        return restResponse;
    }

Java 1.8 version has nice update for data time API.

Here is snippet of code:

    LocalDate lastAprilDay = LocalDate.of(2014, Month.APRIL, 30);
    System.out.println("last april day: " + lastAprilDay);
    LocalDate firstMay = lastAprilDay.plusDays(1);
    System.out.println("should be first may day: " + firstMay);
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd");
    String formatDate = formatter.format(firstMay);
    System.out.println("formatted date: " + formatDate);

Output:

last april day: 2014-04-30
should be first may day: 2014-05-01
formatted date: 01

For more info see Java documentations to this classes:

• LocalDate
• DateTimeFormatter

Updating a Specific Library - scikit-learn:

Anaconda (conda):

conda install scikit-learn

Pip Installs Packages (pip):

pip install --upgrade scikit-learn

Verify Update:

conda list scikit-learn

It should now display the current (and desired) version of the scikit-learn library.

For me personally, I tried using the conda command to update the scikit-learn library and it acted as if it were installing the latest version to then later discover (with an execution of the conda list scikit-learn command) that it was the same version as previously and never updated (or recognized the update?). When I used the pip command, it worked like a charm and correctly updated the scikit-learn library to the latest version!

Hope this helps!

More in-depth details of latest version can be found here (be mindful this applies to the scikit-learn library version of 0.22):

• Release Highlights for scikit-learn 0.22

We have to make sure the type= file with name attribute should be same as the parameter name passed in upload.single('attr')

var multer  = require('multer');
var upload = multer({ dest: 'upload/'});
var fs = require('fs');

/** Permissible loading a single file, 
    the value of the attribute "name" in the form of "recfile". **/
var type = upload.single('recfile');

app.post('/upload', type, function (req,res) {

  /** When using the "single"
      data come in "req.file" regardless of the attribute "name". **/
  var tmp_path = req.file.path;

  /** The original name of the uploaded file
      stored in the variable "originalname". **/
  var target_path = 'uploads/' + req.file.originalname;

  /** A better way to copy the uploaded file. **/
  var src = fs.createReadStream(tmp_path);
  var dest = fs.createWriteStream(target_path);
  src.pipe(dest);
  src.on('end', function() { res.render('complete'); });
  src.on('error', function(err) { res.render('error'); });

});

Also getting

ValueError: Must have equal len keys and value when setting with an iterable,

using .at rather than .loc did not make any difference in my case, but enforcing the datatype of the dataframe column did the trick:

df['B'] = df['B'].astype(object)

Then I could set lists, numpy array and all sorts of things as single cell values in my dataframes.

What's the real result here?

Your program leaked the memory. Depending on your OS, it may have been recovered.

Most modern desktop operating systems do recover leaked memory at process termination, making it sadly common to ignore the problem, as can be seen by many other answers here.)

But you are relying on a safety feature you should not rely upon, and your program (or function) might run on a system where this behaviour does result in a "hard" memory leak, next time.

You might be running in kernel mode, or on vintage / embedded operating systems which do not employ memory protection as a tradeoff. (MMUs take up die space, memory protection costs additional CPU cycles, and it is not too much to ask from a programmer to clean up after himself).

You can use and re-use memory any way you like, but make sure you deallocated all resources before exiting.

Working with VS 2013.
Try the following Tools -> Options -> Debugging -> Output Window -> Module Load Messages -> Off

It will disable the display of modules loaded.

I found the solution here:

http://xinyustudio.wordpress.com/2014/07/02/gradle-sdk-location-not-found-the-problem-and-solution/

Just create a file local.properties and add a line with sdk.dir=SDK_LOCATION

if "ABCD" in "xxxxABCDyyyy":
    # whatever

ctrl-ww Could be useful when you have limited tabs open. But could get annoying when you have too many tabs open.

I type in :NERDTree again to get the focus back on NERDTree tab instantly wherever my cursor's focus is. Hope that helps

document.activeElement.blur();

Works wrong on IE9 - it blurs the whole browser window if active element is document body. Better to check for this case:

if (document.activeElement != document.body) document.activeElement.blur();

Here is another choice: Chaosreader

So I need to debug an application which posts xml to a 3rd party application. I found a brilliant little perl script which does all the hard work – you just chuck it a tcpdump output file, and it does all the manipulation and outputs everything you need...

The script is called chaosreader0.94. See http://www.darknet.org.uk/2007/11/chaosreader-trace-tcpudp-sessions-from-tcpdump/

It worked like a treat, I did the following:

tcpdump host www.blah.com -s 9000 -w outputfile; perl chaosreader0.94 outputfile

Using Quick Watch in Visual Studio you can access the LoaderExceptions from ViewDetails of the thrown exception like this:

($exception).LoaderExceptions

Some great answers above, using that info here is what I did today to solve the same issue:

$to_array = explode(',', $to);
foreach($to_array as $address)
{
    $mail->addAddress($address, 'Web Enquiry');
}

for i in $(seq 1 254); do (ping -c1 -W5 192.168.1.$i >/dev/null && echo "192.168.1.$i" &) ;done

Select Table Column Name where you want to get default value of Current date

 ALTER TABLE 
 [dbo].[Table_Name]
 ADD  CONSTRAINT [Constraint_Name] 
 DEFAULT (getdate()) FOR [Column_Name]

Alter Table Query

Alter TABLE [dbo].[Table_Name](
    [PDate] [datetime] Default GetDate())

you can use the special package "checkinstall" for all packages which are not even in debian/ubuntu yet.

You can use "uupdate" (apt-get install devscripts) to build a package from source with existing debian sources:

Example for libdrm2:

apt-get build-dep libdrm2
apt-get source libdrm2
cd libdrm-2.3.1
uupdate ~/Downloads/libdrm-2.4.1.tar.gz
cd ../libdrm-2.4.1
dpkg-buildpackage -us -uc -nc

To sum things up, there are 4 solutions to this:

Solution 1: turn off ProxyCreation for the DBContext and restore it in the end.

    private DBEntities db = new DBEntities();//dbcontext

    public ActionResult Index()
    {
        bool proxyCreation = db.Configuration.ProxyCreationEnabled;
        try
        {
            //set ProxyCreation to false
            db.Configuration.ProxyCreationEnabled = false;

            var data = db.Products.ToList();

            return Json(data, JsonRequestBehavior.AllowGet);
        }
        catch (Exception ex)
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return Json(ex.Message);
        }
        finally
        {
            //restore ProxyCreation to its original state
            db.Configuration.ProxyCreationEnabled = proxyCreation;
        }
    }

Solution 2: Using JsonConvert by Setting ReferenceLoopHandling to ignore on the serializer settings.

    //using using Newtonsoft.Json;

    private DBEntities db = new DBEntities();//dbcontext

    public ActionResult Index()
    {
        try
        {
            var data = db.Products.ToList();

            JsonSerializerSettings jss = new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore };
            var result = JsonConvert.SerializeObject(data, Formatting.Indented, jss);

            return Json(result, JsonRequestBehavior.AllowGet);
        }
        catch (Exception ex)
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return Json(ex.Message);
        }
    }

Following two solutions are the same, but using a model is better because it's strong typed.

Solution 3: return a Model which includes the needed properties only.

    private DBEntities db = new DBEntities();//dbcontext

    public class ProductModel
    {
        public int Product_ID { get; set;}

        public string Product_Name { get; set;}

        public double Product_Price { get; set;}
    }

    public ActionResult Index()
    {
        try
        {
            var data = db.Products.Select(p => new ProductModel
                                                {
                                                    Product_ID = p.Product_ID,
                                                    Product_Name = p.Product_Name,
                                                    Product_Price = p.Product_Price
                                                }).ToList();

            return Json(data, JsonRequestBehavior.AllowGet);
        }
        catch (Exception ex)
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return Json(ex.Message);
        }
    }

Solution 4: return a new dynamic object which includes the needed properties only.

    private DBEntities db = new DBEntities();//dbcontext

    public ActionResult Index()
    {
        try
        {
            var data = db.Products.Select(p => new
                                                {
                                                    Product_ID = p.Product_ID,
                                                    Product_Name = p.Product_Name,
                                                    Product_Price = p.Product_Price
                                                }).ToList();

            return Json(data, JsonRequestBehavior.AllowGet);
        }
        catch (Exception ex)
        {
            Response.StatusCode = (int)HttpStatusCode.BadRequest;
            return Json(ex.Message);
        }
    }

Github did this using the HTML canvas element.

This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface.

If you use a browser inspector, you see inside every list element a div with a canvas element.

<div class="participation-graph">
   <canvas class="bars" data-color-all="#F5F5F5" data-color-owner="#F5F5F5" data-source="/mxcl/homebrew/graphs/owner_participation" height="80" width="640"></canvas>
</div>

With CSS (z-index, position...) you can put that canvas in the background of a li element or table, in your case.

Do a search about jquery pluggins that fit your requirement.

Hope this pointers help you to achieve that.

Solution in ES6 for modern browsers and IE11 (with transpilation to ES5):

//Disable default IE help popup
window.onhelp = function() {
    return false;
};
window.onkeydown = evt => {
    switch (evt.keyCode) {
        //ESC
        case 27:
            this.onEsc();
            break;
        //F1
        case 112:
            this.onF1();
            break;
        //Fallback to default browser behaviour
        default:
            return true;
    }
    //Returning false overrides default browser event
    return false;
};

It turned out that TCP/IP was enabled for the IPv4 address, but not for the IPv6 address, of THESERVER.

Apparently some connection attempts ended up using IPv4 and others used IPv6.

Enabling TCP/IP for both IP versions resolved the issue.

The fact that SSMS worked turned out to be coincidental (the first few attempts presumably used IPv4). Some later attempts to connect through SSMS resulted in the same error message.

To enable TCP/IP for additional IP addresses:

• Start Sql Server Configuration Manager
• Open the node SQL Server Network Configuration
• Left-click Protocols for MYSQLINSTANCE
• In the right-hand pane, right-click TCP/IP
• Click Properties
• Select the IP Addresses tab
• For each listed IP address, ensure Active and Enabled are both Yes.

Here's a workaround.

Make a template subclass B of A. Do the template-argument-independent part of the construction in A's constructor. Do the template-argument-dependent part in B's constructor.

I had similar problem. I needed to write down csv file on driver while I was connect to cluster in client mode.

I wanted to reuse the same CSV parsing code as Apache Spark to avoid potential errors.

I checked spark-csv code and found code responsible for converting dataframe into raw csv RDD[String] in com.databricks.spark.csv.CsvSchemaRDD.

Sadly it is hardcoded with sc.textFile and the end of relevant method.

I copy-pasted that code and removed last lines with sc.textFile and returned RDD directly instead.

My code:

/*
  This is copypasta from com.databricks.spark.csv.CsvSchemaRDD
  Spark's code has perfect method converting Dataframe -> raw csv RDD[String]
  But in last lines of that method it's hardcoded against writing as text file -
  for our case we need RDD.
 */
object DataframeToRawCsvRDD {

  val defaultCsvFormat = com.databricks.spark.csv.defaultCsvFormat

  def apply(dataFrame: DataFrame, parameters: Map[String, String] = Map())

    val delimiter = parameters.getOrElse("delimiter", ",")

Add -ErrorAction SilentlyContinue to your script and you'll be good to go.

If a function does not return anything, e.g.:

def test():
    pass

it has an implicit return value of None.

Thus, as your pick* methods do not return anything, e.g.:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")

the lines that call them, e.g.:

word = pickEasy()

set word to None, so wordInput in getInput is None. This means that:

if guess in wordInput:

is the equivalent of:

if guess in None:

and None is an instance of NoneType which does not provide iterator/iteration functionality, so you get that type error.

The fix is to add the return type:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

Depends entirely on what you are trying to achieve. Technically, you could just take the first 12 characters from the result of the MD5 hash, but the specification of MD5 is to generate a 32 char one.

Reducing the size of the hash reduces the security, and increases the chance of collisions and the system being broken.

Perhaps if you let us know more about what you are trying to achieve we may be able to assist more.

Any of the above.

There are many, many better things to pontificate. Such as what colour bark suits a tree best, I think vague brown with tinges of dulcet moss.

A longer but more robust version of the accepted answer:

perl -pe 's;(\\*)(\$([a-zA-Z_][a-zA-Z_0-9]*)|\$\{([a-zA-Z_][a-zA-Z_0-9]*)\})?;substr($1,0,int(length($1)/2)).($2&&length($1)%2?$2:$ENV{$3||$4});eg' template.txt

This expands all instances of $VAR or ${VAR} to their environment values (or, if they're undefined, the empty string).

It properly escapes backslashes, and accepts a backslash-escaped $ to inhibit substitution (unlike envsubst, which, it turns out, doesn't do this).

So, if your environment is:

FOO=bar
BAZ=kenny
TARGET=backslashes
NOPE=engi

and your template is:

Two ${TARGET} walk into a \\$FOO. \\\\
\\\$FOO says, "Delete C:\\Windows\\System32, it's a virus."
$BAZ replies, "\${NOPE}s."

the result would be:

Two backslashes walk into a \bar. \\
\$FOO says, "Delete C:\Windows\System32, it's a virus."
kenny replies, "${NOPE}s."

If you only want to escape backslashes before $ (you could write "C:\Windows\System32" in a template unchanged), use this slightly-modified version:

perl -pe 's;(\\*)(\$([a-zA-Z_][a-zA-Z_0-9]*)|\$\{([a-zA-Z_][a-zA-Z_0-9]*)\});substr($1,0,int(length($1)/2)).(length($1)%2?$2:$ENV{$3||$4});eg' template.txt

Try this:

string callbackurl = Request.Url.Host != "localhost" 
    ? Request.Url.Host : Request.Url.Authority;

This will work for local as well as production environment. Because the local uses url with port no that is possible using Url.Host.

MATLAB doesn't respond to Ctrl-C while executing a mex implemented function such as svd. Also when MATLAB is allocating big chunk of memory it doesn't respond. A good practice is to always run your functions for small amount of data, and when all test passes run it for actual scale. When time is an issue, you would want to analyze how much time each segment of code runs as well as their rough time complexity.

This is a quick way to do that, I mean.

It does not use an expensive regex function. It also does not use multiple replacement functions that each individually did loop over the data with several checks, allocations, etc.

So the search is done directly in one for loop. For the number of times that the capacity of the result array has to be increased, a loop is also used within the Array.Copy function. That are all the loops. In some cases, a larger page size might be more efficient.

public static string NormalizeNewLine(this string val)
{
    if (string.IsNullOrEmpty(val))
        return val;

    const int page = 6;
    int a = page;
    int j = 0;
    int len = val.Length;
    char[] res = new char[len];

    for (int i = 0; i < len; i++)
    {
        char ch = val[i];

        if (ch == '\r')
        {
            int ni = i + 1;
            if (ni < len && val[ni] == '\n')
            {
                res[j++] = '\r';
                res[j++] = '\n';
                i++;
            }
            else
            {
                if (a == page) // Ensure capacity
                {

                    Array.Copy(res, 0, nres, 0, res.Length);
                    res = nres;
                    a = 0;
                }

                res[j++] = '\r';
                res[j++] = '\n';

            {
                if (a == page) // Ensure capacity
                {
                    char[] nres = new char[res.Length + page];
                    Array.Copy(res, 0, nres, 0, res.Length);
                    res = nres;
                    a = 0;
                }

                res[j++] = '\r';
                res[j++] = '\n';
                a++;
            }
        }
        else
        {
            res[j++] = ch;
        }
    }

    return new string(res, 0, j);
}

I now that '\n\r' is not actually used on basic platforms. But who would use two types of linebreaks in succession to indicate two linebreaks?

If you want to know that, then you need to take a look before to know if the \n and \r both are used separately in the same document.

If you find yourself doing things like this regularly it may be worth investigating the object-oriented interface to matplotlib. In your case:

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(5)
y = np.exp(x)
fig1, ax1 = plt.subplots()
ax1.plot(x, y)
ax1.set_title("Axis 1 title")
ax1.set_xlabel("X-label for axis 1")

z = np.sin(x)
fig2, (ax2, ax3) = plt.subplots(nrows=2, ncols=1) # two axes on figure
ax2.plot(x, z)
ax3.plot(x, -z)

w = np.cos(x)
ax1.plot(x, w) # can continue plotting on the first axis

It is a little more verbose but it's much clearer and easier to keep track of, especially with several figures each with multiple subplots.

UltraID3Lib...

Be aware that UltraID3Lib is no longer officially available, and thus no longer maintained. See comments below for the link to a Github project that includes this library

//using HundredMilesSoftware.UltraID3Lib;
UltraID3 u = new UltraID3();
u.Read(@"C:\mp3\song.mp3");
//view
Console.WriteLine(u.Artist);
//edit
u.Artist = "New Artist";
u.Write();

This is what we use in ASP.NET:

// Stop Caching in IE
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);

// Stop Caching in Firefox
Response.Cache.SetNoStore();

It stops caching in Firefox and IE, but we haven't tried other browsers. The following response headers are added by these statements:

Cache-Control: no-cache, no-store
Pragma: no-cache

Example simple (worked):

var a=Number.parseFloat($("#budget_project").val()); // from input field
var b=Number.parseFloat(html); // from ajax
var c=a-b;
$("#result").html(c.toFixed(2)); // put to id='result' (div or others)

Note: The title of this question used to be something like "How to printf in python?"

Since people may come here looking for it based on the title, Python also supports printf-style substitution:

>>> strings = [ "one", "two", "three" ]
>>>
>>> for i in xrange(3):
...     print "Item %d: %s" % (i, strings[i])
...
Item 0: one
Item 1: two
Item 2: three

And, you can handily multiply string values:

>>> print "." * 10
..........

GIF is limited to 256 colors and do not support real transparency. You should use PNG instead of GIF because it offers better compression and features. PNG is great for small and simple images like logos, icons, etc.

JPEG has better compression with complex images like photos.

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")

Things have changed since this question was posted, now with new Google Services API, you can prompt users to enable GPS:

You will need to request ACCESS_FINE_LOCATION permission in your manifest:

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

Also watch this video:

Use:

$(#id/.class).show()
$(#id/.class).hide()

This one is the best way.

You can use the box-shadow property on a tr element as a subtitute for a border. As a plus, any border-radius property on the same element will also apply to the box shadow.

box-shadow: 0px 0px 0px 1px rgb(0, 0, 0);

Since Ubuntu 18.04 installing Intellij IDEA is easy! You just need to search "IDEA" in Software Center. Also you're able to choose a branch to install (I use EAP).

For earlier versions:

According to this (snap) and this (umake) articles the most comfortable ways are:

• to use snap-packages (since versions IDEA 2017.3 & Ubuntu 14.04):

  1. install snapd system. Since Ubuntu 16.04 you already have it.

  2. install IDEA snap-package or even EAP build

• to use ubuntu-make (for Ubuntu versions earlier than 16.04 use apt-get command instead apt):

  1. Add PPA ubuntu-desktop/ubuntu-make (if you install ubuntu-make from standard repo you'll see only a few IDE's):

     $ sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
     

  2. Install ubuntu-make:

     $ sudo apt update
     $ sudo apt install ubuntu-make
     

  3. install preffered ide (IDEA, for this question):

     $ umake ide idea
     

     or even ultimate version if you need:

     $ umake ide idea-ultimate
     

  4. I upgrade Intellij IDEA via reinstalling it:

     $ umake -r ide idea-ultimate

     $ umake ide idea-ultimate

and GCC claim compatibility with Microsoft's compiler.:

http://gcc.gnu.org/onlinedocs/gcc/Structure_002dPacking-Pragmas.html

In addition to the previous answers, please note that regardless the packaging, there is no members-order-guarantee in C++. Compilers may (and certainly do) add virtual table pointer and base structures' members to the structure. Even the existence of virtual table is not ensured by the standard (virtual mechanism implementation is not specified) and therefore one can conclude that such guarantee is just impossible.

I'm quite sure member-order is guaranteed in C, but I wouldn't count on it, when writing a cross-platform or cross-compiler program.

You could get first rows of Spark DataFrame with head and then create Pandas DataFrame:

l = [('Alice', 1),('Jim',2),('Sandra',3)]
df = sqlContext.createDataFrame(l, ['name', 'age'])

df_pandas = pd.DataFrame(df.head(3), columns=df.columns)

In [4]: df_pandas
Out[4]: 
     name  age
0   Alice    1
1     Jim    2
2  Sandra    3

I ended up using hexdump to convert the binary files to there hex representation and then opened them in meld / kompare / any other diff tool. Unlike you I was after the differences in the files.

hexdump tmp/Circle_24.png > tmp/hex1.txt
hexdump /tmp/Circle_24.png > tmp/hex2.txt

meld tmp/hex1.txt tmp/hex2.txt

You might just have to install the packages.

yum install php-pdo php-mysqli

After they're installed, restart Apache.

httpd restart

or

apachectl restart

The abstract annotation to a method indicates that the method MUST be overriden in a subclass.

In Java, a static member (method or field) cannot be overridden by subclasses (this is not necessarily true in other object oriented languages, see SmallTalk.) A static member may be hidden, but that is fundamentally different than overridden.

Since static members cannot be overriden in a subclass, the abstract annotation cannot be applied to them.

As an aside - other languages do support static inheritance, just like instance inheritance. From a syntax perspective, those languages usually require the class name to be included in the statement. For example, in Java, assuming you are writing code in ClassA, these are equivalent statements (if methodA() is a static method, and there is no instance method with the same signature):

ClassA.methodA();

and

methodA();

In SmallTalk, the class name is not optional, so the syntax is (note that SmallTalk does not use the . to separate the "subject" and the "verb", but instead uses it as the statemend terminator):

ClassA methodA.

Because the class name is always required, the correct "version" of the method can always be determined by traversing the class hierarchy. For what it's worth, I do occasionally miss static inheritance, and was bitten by the lack of static inheritance in Java when I first started with it. Additionally, SmallTalk is duck-typed (and thus doesn't support program-by-contract.) Thus, it has no abstract modifier for class members.

I recently wrote on this topic, though this post it old, I thought it will be helpful to someone who wants to know how to implement BaseAdapter.notifyDataSetChanged() step by step and in a correct way.

Other proposals are a little cryptic, so I thought I'd contribute:

Object.prop = function(obj, prop, val){
    var props = prop.split('.')
      , final = props.pop(), p 
    while(p = props.shift()){
        if (typeof obj[p] === 'undefined')
            return undefined;
        obj = obj[p]
    }
    return val ? (obj[final] = val) : obj[final]
}

var obj = { a: { b: '1', c: '2' } }

// get
console.log(Object.prop(obj, 'a.c')) // -> 2
// set
Object.prop(obj, 'a.c', function(){})
console.log(obj) // -> { a: { b: '1', c: [Function] } }

I was running into the same issue when my callbacks would try to show a dialog.

I solved it with dedicated methods in the Activity - at the Activity instance member level - that use runOnUiThread(..)

public void showAuthProgressDialog() {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            mAuthProgressDialog = DialogUtil.getVisibleProgressDialog(SignInActivity.this, "Loading ...");
        }
    });
}

public void dismissAuthProgressDialog() {
    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            if (mAuthProgressDialog == null || ! mAuthProgressDialog.isShowing()) {
                return;
            }
            mAuthProgressDialog.dismiss();
        }
    });
}

With all respect the most likely thing is that you are mistaken about why the click is being 'rejected'. Why do you think some program is trying to determine if it's human or not? The Robot class (have used it a lot) should send messages that the operating system has no way to distinguish from a user doing the click.

img need src to use border is remover, i no know a why css is crazy

data:image/gif;base64,R0lGODlhAQABAPcAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAP8ALAAAAAABAAEAAAgEAP8FBAA7

So try example with SRC:

img.logo {_x000D_
 width: 200px;_x000D_
    height: 50px;_x000D_
 background: url(http://cdn.sstatic.net/Sites/stackoverflow/img/sprites.svg) no-repeat top left;_x000D_
}

<img class="logo" src="data:image/gif;base64,R0lGODlhAQABAPcAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAEAAP8ALAAAAAABAAEAAAgEAP8FBAA7">

So try example without SRC:

img.logo {_x000D_
 width: 200px;_x000D_
    height: 50px;_x000D_
 background: url(http://cdn.sstatic.net/Sites/stackoverflow/img/sprites.svg) no-repeat top left;_x000D_
}

<img class="logo">

lol... css crazy! good fun

You really should use an established library, such as Newtonsoft.Json (which even Microsoft uses for frameworks such as MVC and WebAPI), or .NET's built-in JavascriptSerializer.

Here's a sample of reading JSON using Newtonsoft.Json:

JObject o1 = JObject.Parse(File.ReadAllText(@"c:\videogames.json"));

// read JSON directly from a file
using (StreamReader file = File.OpenText(@"c:\videogames.json"))
using (JsonTextReader reader = new JsonTextReader(file))
{
  JObject o2 = (JObject) JToken.ReadFrom(reader);
}

Now it's also possible to reset the database through their web interface.

Go to dashboard.heroku.com select your app and then you'll find the database under the add-ons category, click on it and then you can reset the database.

It is possible to use the convert function here, but 36 characters are enough to hold the unique identifier value:

convert(nvarchar(36), requestID) as requestID

It's wonderful to finally have this solved without using a hack.

Short answer:
install Remote Server Administration tools on your SQL Server (it's an optional feature of Windows Server), reboot, then run SQL Server configuration manager, access the service settings for each of the services whose logon account starts with "NT Service...", clear out the password fields and restart the service. Under the covers, SQL Server Config manager will assign these virtual accounts the Log On as a Service right, and you'll be on your way.

tl;dr;

There is a catch-22 between default settings for a windows domain and default install of SQL Server 2012.

As mentioned above, default Windows domain setup will indeed prevent you from defining the "log on as a service" right via Group Policy Edit at the local machine (via GUI at least; if you install Powershell ActiveDirectory module (via Remote Server Administration tools download) you can do it by scripting.

And, by default, SQL Server 2012 setup runs services in "virtual accounts" (NT Service\ prefix, e.g, NT Service\MSSQLServer. These are like local machine accounts, not domain accounts, but you still can't assign them log on as service rights if your server is joined to a domain. SQL Server setup attempts to assign the right at install, and the SQL Server Config Management tool likewise attempts to assign the right when you change logon account.

And the beautiful catch-22 is this: SQL Server tools depend on (some component of) RSAT to assign the logon as service right. If you don't happen to have RSAT installed on your member server, SQL Server Config Manager fails silently trying to apply the setting (despite all the gaudy pre-installation verification it runs) and you end up with services that won't start.

The one hint of this requirement that I was able to find in the blizzard of SQL Server and Virtual Account doc was this: https://msdn.microsoft.com/en-us/library/ms143504.aspx#New_Accounts, search for RSAT.

Usually I use the === (triple equals) and __LINE__ , __CLASS__ to locate the error in my code:

$query=mysql_query('SELECT champ FROM table')
or die("SQL Error line  ".__LINE__ ." class ".__CLASS__." : ".mysql_error());

mysql_close();

if(mysql_num_rows($query)===0)
{
    PERFORM ACTION;
}
else
{
    while($r=mysql_fetch_row($query))
    {
          PERFORM ACTION;
    }
}

In my case i had to move the html code of the element i wanted at the front at the end of the html file, because if one element has z-index and the other doesn't have z index it doesn't work.

Yet another serializer out there that claims to be super fast is netserializer.

The data given on their site shows performance of 2x - 4x over protobuf, I have not tried this myself, but if you are evaluating various options, try this as well

A = filename

ftp = ftplib.FTP("IP")
ftp.login("USR Name", "Pass")
ftp.cwd("/Dir")


try:
    ftp.retrbinary("RETR " + filename ,open(A, 'wb').write)
except:
    print "Error"

import sys
sys.stderr.write()

Is my choice, just more readable and saying exactly what you intend to do and portable across versions.

Edit: being 'pythonic' is a third thought to me over readability and performance... with these two things in mind, with python 80% of your code will be pythonic. list comprehension being the 'big thing' that isn't used as often (readability).

Summarizing the Answers

I can see many different answers and ways to do this but there is the rub in this and that is the objective.

Yes, the objective. If you want to only know the column names you can use

SELECT * FROM my_table WHERE 1=0
or
SELECT TOP 0 * FROM my_table

But if you want to use those columns somewhere or simply say manipulate them then the quick queries above are not going to be of any use. You need to use

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = N'Customers'

one more way to know some specific columns where we are in need of some similar columns

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME like N'%[ColumnName]%' and TABLE_NAME = N'[TableName]'

Although it is much easier to restore database using SSMS as stated in many answers. You can also restore Database using .bak with SQL server query, for example

RESTORE DATABASE AdventureWorks2012 FROM DISK = 'D:\AdventureWorks2012.BAK'
GO

In above Query you need to keep in mind about .mdf/.ldf file location. You might get error

System.Data.SqlClient.SqlError: Directory lookup for the file "C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\AdventureWorks.MDF" failed with the operating system error 3(The system cannot find the path specified.). (Microsoft.SqlServer.SmoExtended)

So you need to run Query as below

RESTORE FILELISTONLY 
FROM DISK = 'D:\AdventureWorks2012.BAK'

Once you will run above Query you will get location of mdf/ldf use it Restore database using query

USE MASTER
GO
RESTORE DATABASE DBASE 
FROM DISK = 'D:\AdventureWorks2012.BAK'
WITH 
MOVE 'DBASE' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE.MDF',
MOVE 'DBASE_LOG' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.DBASE\MSSQL\DATA\DBASE_1.LDF', 
NOUNLOAD,  REPLACE,  NOUNLOAD,  STATS = 5
GO

I ended up finding it through the IntelliSense on the get() function. So, I'll post it here for anyone who is looking for similar information.

Anyways, the syntax is nearly identical, but slightly different. Instead of using URLSearchParams() the parameters need to be initialized as HttpParams() and the property within the get() function is now called params instead of search.

import { HttpClient, HttpParams } from '@angular/common/http';

getLogs(logNamespace): Observable<any> {

    // Setup log namespace query parameter
    let params = new HttpParams().set('logNamespace', logNamespace);

    return this._HttpClient.get(`${API_URL}/api/v1/data/logs`, { params: params })
}

I actually prefer this syntax as its a little more parameter agnostic. I also refactored the code to make it slightly more abbreviated.

getLogs(logNamespace): Observable<any> {

    return this._HttpClient.get(`${API_URL}/api/v1/data/logs`, {
        params: new HttpParams().set('logNamespace', logNamespace)
    })
}

Multiple Parameters

The best way I have found thus far is to define a Params object with all of the parameters I want to define defined within. As @estus pointed out in the comment below, there are a lot of great answers in This Question as to how to assign multiple parameters.

getLogs(parameters) {

    // Initialize Params Object
    let params = new HttpParams();

    // Begin assigning parameters
    params = params.append('firstParameter', parameters.valueOne);
    params = params.append('secondParameter', parameters.valueTwo);

    // Make the API call using the new parameters.
    return this._HttpClient.get(`${API_URL}/api/v1/data/logs`, { params: params })

Multiple Parameters with Conditional Logic

Another thing I often do with multiple parameters is allow the use of multiple parameters without requiring their presence in every call. Using Lodash, it's pretty simple to conditionally add/remove parameters from calls to the API. The exact functions used in Lodash or Underscores, or vanilla JS may vary depending on your application, but I have found that checking for property definition works pretty well. The function below will only pass parameters that have corresponding properties within the parameters variable passed into the function.

getLogs(parameters) {

    // Initialize Params Object
    let params = new HttpParams();

    // Begin assigning parameters
    if (!_.isUndefined(parameters)) {
        params = _.isUndefined(parameters.valueOne) ? params : params.append('firstParameter', parameters.valueOne);
        params = _.isUndefined(parameters.valueTwo) ? params : params.append('secondParameter', parameters.valueTwo);
    }

    // Make the API call using the new parameters.
    return this._HttpClient.get(`${API_URL}/api/v1/data/logs`, { params: params })

Did you try to give the layout_width and layout_height like the following? Since you are setting with wrap_content, the image button expands to the size of source image's height and width.

<blink>    
  <ImageButton>
    android:id="@+id/Button01"
    android:scaleType="fitXY" 
    android:layout_width="80dip"
    android:layout_height="80dip"
    android:cropToPadding="false"
    android:paddingLeft="10dp"
    android:src="@drawable/eye"> 
  </ImageButton>
</blink>

Map is an interface; HashMap is a particular implementation of that interface.

HashMap uses a collection of hashed key values to do its lookup. TreeMap will use a red-black tree as its underlying data store.

A quick add-on to mpenkov's answer above (didn't want this to get lost in the comments)

For me, I had to install pip for 3.6 first

sudo apt install python3-pip

now you can install python 3.7

sudo apt install python3.7

and then I could install pip for 3.7

python3.7 -m pip install pip

and as a bonus, to install other modules just preface with

python3.7 -m pip install <module>

EDIT 1 (12/2019):

I know this is obvious for most. but if you want python 3.8, just substitute python3.8 in place of python3.7

EDIT 2 (5/2020):

For those that are able to upgrade, Python 3.8 is available out-of-the-box for Ubuntu 20.04 which was released a few weeks ago.
