You will have to use something like below

#menu ul{_x000D_
  list-style: none;_x000D_
}_x000D_
#menu li{_x000D_
  display: inline;_x000D_
}_x000D_
 

<div id="menu">_x000D_
  <ul>_x000D_
    <li>First menu item</li>_x000D_
    <li>Second menu item</li>_x000D_
    <li>Third menu item</li>_x000D_
  </ul>_x000D_
</div>

To clear the datagridview write the following code:

dataGridView1.DataSource=null;

I recommend you to use Attesoro (http://attesoro.org/). Is simple and easy to use. And is made in java.

the documentation has this blurb https://requests.readthedocs.io/en/master/user/quickstart/#redirection-and-history

import requests

r = requests.get('http://www.github.com')
r.url
#returns https://www.github.com instead of the http page you asked for 

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

Consider a example where I have two databases namely allmsa.db and atlanta.db. Say the database allmsa.db has tables for all msas in US and database atlanta.db is empty.

Our target is to copy the table atlanta from allmsa.db to atlanta.db.

Steps

1. sqlite3 atlanta.db(to go into atlanta database)
2. Attach allmsa.db. This can be done using the command ATTACH '/mnt/fastaccessDS/core/csv/allmsa.db' AS AM; note that we give the entire path of the database to be attached.
3. check the database list using sqlite> .databases you can see the output as

seq  name             file                                                      
---  ---------------  ----------------------------------------------------------
0    main             /mnt/fastaccessDS/core/csv/atlanta.db                  
2    AM               /mnt/fastaccessDS/core/csv/allmsa.db 

4. now you come to your actual target. Use the command INSERT INTO atlanta SELECT * FROM AM.atlanta;

This should serve your purpose.

The Magrittr way

I know there is an accepted answer already, but I wanted to show one cool way to do it in single command with the help of magrittr package.

PlantGrowth %$% # open dataset and make colnames accessible with '$'
split(weight,group) %T>% # split by group and side-pipe it into boxplot
boxplot %>% # plot
lapply(mean) %>% # data from split can still be used thanks to side-pipe '%T>%'
unlist %T>% # convert to atomic and side-pipe it to points
points(pch=18)  %>% # add points for means to the boxplot
text(x=.+0.06,labels=.) # use the values to print text

This code will produce a boxplot with means printed as points and values:

I split the command on multiple lines so I can comment on what each part does, but it can also be entered as a oneliner. You can learn more about this in my gist.

In my case, you need to convert the column(you think this column is numeric, but actually not) to numeric

geom_segment(data=tmpp, 
   aes(x=start_pos, 
   y=lib.complexity, 
   xend=end_pos, 
   yend=lib.complexity)
)
# to 
geom_segment(data=tmpp, 
   aes(x=as.numeric(start_pos), 
   y=as.numeric(lib.complexity), 
   xend=as.numeric(end_pos), 
   yend=as.numeric(lib.complexity))
)

Your best bet is KissFFT - as its name implies it's simple, but it's still quite respectably fast, and a lot more lightweight than FFTW. It's also free, wheras FFTW requires a hefty licence fee if you want to include it in a commercial product.

Simple way to delete all file from directory :

It is generic function for delete all images from directory by calling only

deleteAllImageFile(context);

public static void deleteAllFile(Context context) {
File directory = context.getExternalFilesDir(null);
        if (directory.isDirectory()) {
            for (String fileName: file.list()) {
                new File(file,fileName).delete();
            }
        }    
    } 

Ah yes, that is how it is intended in SQL. You get the Max of every column seperately. It seems like you want to return values from the row with the max date, so you have to select the row with the max date. I prefer to do this with a subselect, as the queries keep compact easy to read.

SELECT TrainingID, CompletedDate, Notes
FROM HR_EmployeeTrainings ET 
WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID) 
AND CompletedDate in 
   (Select Max(CompletedDate) from HR_EmployeeTrainings B
    where B.TrainingID = ET.TrainingID)

If you also want to match by AntiRecID you should include that in the subselect as well.

I came to this post by way of better understanding the inference of the infamous quote from Mac Lane's Category Theory For the Working Mathematician.

In describing what something is, it's often equally useful to describe what it's not.

The fact that Mac Lane uses the description to describe a Monad, one might imply that it describes something unique to monads. Bear with me. To develop a broader understanding of the statement, I believe it needs to be made clear that he is not describing something that is unique to monads; the statement equally describes Applicative and Arrows among others. For the same reason we can have two monoids on Int (Sum and Product), we can have several monoids on X in the category of endofunctors. But there is even more to the similarities.

Both Monad and Applicative meet the criteria:

• endo => any arrow, or morphism that starts and ends in the same place
• functor => any arrow, or morphism between two Categories

  (e.g., in day to day Tree a -> List b, but in Category Tree -> List)

• monoid => single object; i.e., a single type, but in this context, only in regards to the external layer; so, we can't have Tree -> List, only List -> List.

The statement uses "Category of..." This defines the scope of the statement. As an example, the Functor Category describes the scope of f * -> g *, i.e., Any functor -> Any functor, e.g., Tree * -> List * or Tree * -> Tree *.

What a Categorical statement does not specify describes where anything and everything is permitted.

In this case, inside the functors, * -> * aka a -> b is not specified which means Anything -> Anything including Anything else. As my imagination jumps to Int -> String, it also includes Integer -> Maybe Int, or even Maybe Double -> Either String Int where a :: Maybe Double; b :: Either String Int.

So the statement comes together as follows:

• functor scope :: f a -> g b (i.e., any parameterized type to any parameterized type)
• endo + functor :: f a -> f b (i.e., any one parameterized type to the same parameterized type) ... said differently,
• a monoid in the category of endofunctor

So, where is the power of this construct? To appreciate the full dynamics, I needed to see that the typical drawings of a monoid (single object with what looks like an identity arrow, :: single object -> single object), fails to illustrate that I'm permitted to use an arrow parameterized with any number of monoid values, from the one type object permitted in Monoid. The endo, ~ identity arrow definition of equivalence ignores the functor's type value and both the type and value of the most inner, "payload" layer. Thus, equivalence returns true in any situation where the functorial types match (e.g., Nothing -> Just * -> Nothing is equivalent to Just * -> Just * -> Just * because they are both Maybe -> Maybe -> Maybe).

Sidebar: ~ outside is conceptual, but is the left most symbol in f a. It also describes what "Haskell" reads-in first (big picture); so Type is "outside" in relation to a Type Value. The relationship between layers (a chain of references) in programming is not easy to relate in Category. The Category of Set is used to describe Types (Int, Strings, Maybe Int etc.) which includes the Category of Functor (parameterized Types). The reference chain: Functor Type, Functor values (elements of that Functor's set, e.g., Nothing, Just), and in turn, everything else each functor value points to. In Category the relationship is described differently, e.g., return :: a -> m a is considered a natural transformation from one Functor to another Functor, different from anything mentioned thus far.

Back to the main thread, all in all, for any defined tensor product and a neutral value, the statement ends up describing an amazingly powerful computational construct born from its paradoxical structure:

• on the outside it appears as a single object (e.g., :: List); static
• but inside, permits a lot of dynamics
  • any number of values of the same type (e.g., Empty | ~NonEmpty) as fodder to functions of any arity. The tensor product will reduce any number of inputs to a single value... for the external layer (~fold that says nothing about the payload)
  • infinite range of both the type and values for the inner most layer

In Haskell, clarifying the applicability of the statement is important. The power and versatility of this construct, has absolutely nothing to do with a monad per se. In other words, the construct does not rely on what makes a monad unique.

When trying to figure out whether to build code with a shared context to support computations that depend on each other, versus computations that can be run in parallel, this infamous statement, with as much as it describes, is not a contrast between the choice of Applicative, Arrows and Monads, but rather is a description of how much they are the same. For the decision at hand, the statement is moot.

This is often misunderstood. The statement goes on to describe join :: m (m a) -> m a as the tensor product for the monoidal endofunctor. However, it does not articulate how, in the context of this statement, (<*>) could also have also been chosen. It truly is a an example of six/half dozen. The logic for combining values are exactly alike; same input generates the same output from each (unlike the Sum and Product monoids for Int because they generate different results when combining Ints).

So, to recap: A monoid in the category of endofunctors describes:

   ~t :: m * -> m * -> m *
   and a neutral value for m *

(<*>) and (>>=) both provide simultaneous access to the two m values in order to compute the the single return value. The logic used to compute the return value is exactly the same. If it were not for the different shapes of the functions they parameterize (f :: a -> b versus k :: a -> m b) and the position of the parameter with the same return type of the computation (i.e., a -> b -> b versus b -> a -> b for each respectively), I suspect we could have parameterized the monoidal logic, the tensor product, for reuse in both definitions. As an exercise to make the point, try and implement ~t, and you end up with (<*>) and (>>=) depending on how you decide to define it forall a b.

If my last point is at minimum conceptually true, it then explains the precise, and only computational difference between Applicative and Monad: the functions they parameterize. In other words, the difference is external to the implementation of these type classes.

In conclusion, in my own experience, Mac Lane's infamous quote provided a great "goto" meme, a guidepost for me to reference while navigating my way through Category to better understand the idioms used in Haskell. It succeeds at capturing the scope of a powerful computing capacity made wonderfully accessible in Haskell.

However, there is irony in how I first misunderstood the statement's applicability outside of the monad, and what I hope conveyed here. Everything that it describes turns out to be what is similar between Applicative and Monads (and Arrows among others). What it doesn't say is precisely the small but useful distinction between them.

ArrayList<Customer> custArr = new ArrayList<Customer>();
while(youWantToContinue) {
    //get a customerName
    //get an amount
    custArr.add(new Customer(customerName, amount);
}

For this to work... you'll have to fix your constructor...

Assuming your Customer class has variables called name and sale, your constructor should look like this:

public Customer(String customerName, double amount) {
    name = customerName;
    sale = amount;
}

Change your Store class to something more like this:

public class Store {

    private ArrayList<Customer> custArr;

    public new Store() {
        custArr = new ArrayList<Customer>();
    }

    public void addSale(String customerName, double amount) {
        custArr.add(new Customer(customerName, amount));
    }

    public Customer getSaleAtIndex(int index) {
        return custArr.get(index);
    }

    //or if you want the entire ArrayList:
    public ArrayList getCustArr() {
        return custArr;
    }
}

The top ranked answer to this question suggests using the readLine() method to take in user input from the command line. However, I want to note that you need to use the ! operator when calling this method to return a string instead of an optional:

var response = readLine()!

You can simply do git pull origin branchname. It will fetch the latest commit again.

In my case, I found that placing a here document (like sqplus ... << EOF) statements indented also raise the same error as shown below:

./dbuser_case.ksh: line 25: syntax error: unexpected end of file

So after removing the indentation for this, then it went fine.

Hope it helps...

If you have a BASH shell on your mac/linux in-front of you, you try out the below steps to understand the redirection practically :

Create a 2 line script called zz.sh

#!/bin/bash
echo "Hello. This is a proper command"
junk_errorcommand

• The echo command's output goes into STDOUT filestream (file descriptor 1).
• The error command's output goes into STDERR filestream (file descriptor 2)

Currently, simply executing the script sends both STDOUT and STDERR to the screen.

./zz.sh

Now start with the standard redirection :

zz.sh > zfile.txt

In the above, "echo" (STDOUT) goes into the zfile.txt. Whereas "error" (STDERR) is displayed on the screen.

The above is the same as :

zz.sh 1> zfile.txt

Now you can try the opposite, and redirect "error" STDERR into the file. The STDOUT from "echo" command goes to the screen.

zz.sh 2> zfile.txt

Combining the above two, you get:

zz.sh 1> zfile.txt 2>&1

Explanation:

• FIRST, send STDOUT 1 to zfile.txt
• THEN, send STDERR 2 to STDOUT 1 itself (by using &1 pointer).
• Therefore, both 1 and 2 goes into the same file (zfile.txt)

Eventually, you can pack the whole thing inside nohup command & to run it in the background:

nohup zz.sh 1> zfile.txt 2>&1&

Try:

text-align: center;

You may be familiar with the HTML align attribute (which has been discontinued as of HTML 5). The align attribute could be used with tags such as

<table>, <td>, and <img> 

to specify the alignment of these elements. This attribute allowed you to align elements horizontally. HTML also has/had a valign attribute for aligning elements vertically. This has also been discontinued from HTML5.

These attributes were discontinued in favor of using CSS to set the alignment of HTML elements.

There isn't actually a CSS align or CSS valign property. Instead, CSS has the text-align which applies to inline content of block-level elements, and vertical-align property which applies to inline level and table cells.

string actionName = this.ControllerContext.RouteData.Values["action"].ToString();
string controllerName = this.ControllerContext.RouteData.Values["controller"].ToString();

A much shorter version for getting a list of all subclasses:

from itertools import chain

def subclasses(cls):
    return list(
        chain.from_iterable(
            [list(chain.from_iterable([[x], subclasses(x)])) for x in cls.__subclasses__()]
        )
    )

You can use the global keyword to solve this.

Assume that you want to declare a variable called isFromManageUserAccount as a global variable you can use the following code.

global.isFromManageUserAccount=false;

After declaring like this you can use this variable anywhere in the application.

<?php
$myArray = new array('1', '2');
$seralizedArray = serialize($myArray);
?>

XStream is pretty good at serializing object to XML without much configuration and money! (it's under BSD license).

We used it in one of our project to replace the plain old java-serialization and it worked almost out of the box.

Read these tutorials Asp.net Update Panel and Introduction to the UpdatePanel Control

To add on:

you can insert a time check within a loop with intensive or possible deadlock, ie.

:
section_toc_conditionalBreakOff;
:

where within this section

if (toc > timeRequiredToBreakOff)     % time conditional break off
      return;
      % other options may be:                         
      % 1. display intermediate values with pause;
      % 2. exit;                           % in some cases, extreme : kill/ quit matlab
end

Store your data in temp table

Select * into tempTable from table1

Now update the column

 UPDATE table1
    SET table1.FileName = (select FileName from tempTable where tempTable.id = table1.ID);

reflect.DeepEqual is often incorrectly used to compare two like structs, as in your question.

cmp.Equal is a better tool for comparing structs.

To see why reflection is ill-advised, let's look at the documentation:

Struct values are deeply equal if their corresponding fields, both exported and unexported, are deeply equal.

....

numbers, bools, strings, and channels - are deeply equal if they are equal using Go's == operator.

If we compare two time.Time values of the same UTC time, t1 == t2 will be false if their metadata timezone is different.

go-cmp looks for the Equal() method and uses that to correctly compare times.

Example:

m1 := map[string]int{
    "a": 1,
    "b": 2,
}
m2 := map[string]int{
    "a": 1,
    "b": 2,
}
fmt.Println(cmp.Equal(m1, m2)) // will result in true

I prefer this variant on the enumerator method with a pipeline, because you don't have to refer to the hash table in the foreach (tested in PowerShell 5):

$hash = @{
    'a' = 3
    'b' = 2
    'c' = 1
}
$hash.getEnumerator() | foreach {
    Write-Host ("Key = " + $_.key + " and Value = " + $_.value);
}

Output:

Key = c and Value = 1
Key = b and Value = 2
Key = a and Value = 3

Now, this has not been deliberately sorted on value, the enumerator simply returns the objects in reverse order.

But since this is a pipeline, I now can sort the objects received from the enumerator on value:

$hash.getEnumerator() | sort-object -Property value -Desc | foreach {
  Write-Host ("Key = " + $_.key + " and Value = " + $_.value);
}

Output:

Key = a and Value = 3
Key = b and Value = 2
Key = c and Value = 1

The way I usually do it is subtracting the two DateTime and this gets me a TimeSpan that will tell me the diff.

Here's an example:

DateTime start = DateTime.Now;
// Do some work
TimeSpan timeDiff = DateTime.Now - start;
timeDiff.TotalMilliseconds;

Here is a solution using hooks, Timer component, I'm replicating same logic above with hooks

import React from 'react'
import { useState, useEffect } from 'react';

const Timer = (props:any) => {
    const {initialMinute = 0,initialSeconds = 0} = props;
    const [ minutes, setMinutes ] = useState(initialMinute);
    const [seconds, setSeconds ] =  useState(initialSeconds);
    useEffect(()=>{
    let myInterval = setInterval(() => {
            if (seconds > 0) {
                setSeconds(seconds - 1);
            }
            if (seconds === 0) {
                if (minutes === 0) {
                    clearInterval(myInterval)
                } else {
                    setMinutes(minutes - 1);
                    setSeconds(59);
                }
            } 
        }, 1000)
        return ()=> {
            clearInterval(myInterval);
          };
    });

    return (
        <div>
        { minutes === 0 && seconds === 0
            ? null
            : <h1> {minutes}:{seconds < 10 ?  `0${seconds}` : seconds}</h1> 
        }
        </div>
    )
}

export default Timer;

The problem is caused by using the style="display:none", you should hide the alert with Javascript or at least when showing it, remove the style attribute.

Eloquent::insert is the proper solution but it wont update the timestamps, so you can do something like below

 $json_array=array_map(function ($a) { 
                        return array_merge($a,['created_at'=> 
                                            Carbon::now(),'updated_at'=> Carbon::now()]
                                           ); 
                                     }, $json_array); 
 Model::insert($json_array);

The idea is to add created_at and updated_at on whole array before doing insert

1. String otherString = "helen" + character;

2. otherString +=  character;

Feeela is right but you can get a parent div contracting or expanding to a child element if you reverse your div positioning like this:

.parent {
    position: absolute;
    /* position it in the browser using the `left`, `top` and `margin` 
       attributes */
}

.child {
    position: relative;
    height: 100%;
    width: 100%;

    overflow: hidden;
    /* to pad or move it around using `left` and `top` inside the parent */
}

This should work for you.

This can be archived by adding code on the onchange event of the select control.

For Example:

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">

ReDim aFirstArray(0)

This will resize the array to zero and erase all data.

You can free memory used by vector by this way:

//Removes all elements in vector
v.clear()

//Frees the memory which is not used by the vector
v.shrink_to_fit();

Key in 1 + G and it will take you to the beginning of the file. Converserly, G will take you to the end of the file.

Could you please have a look at: http://jsfiddle.net/4Zw3M/1/.

Basically, the data is stored in an Array and the options are added accordingly. I think the code says more than a thousand words.

var data = [ // The data
    ['ten', [
        'eleven','twelve'
    ]],
    ['twenty', [
        'twentyone', 'twentytwo'
    ]]
];

$a = $('#a'); // The dropdowns
$b = $('#b');

for(var i = 0; i < data.length; i++) {
    var first = data[i][0];
    $a.append($("<option>"). // Add options
       attr("value",first).
       data("sel", i).
       text(first));
}

$a.change(function() {
    var index = $(this).children('option:selected').data('sel');
    var second = data[index][1]; // The second-choice data

    $b.html(''); // Clear existing options in second dropdown

    for(var j = 0; j < second.length; j++) {
        $b.append($("<option>"). // Add options
           attr("value",second[j]).
           data("sel", j).
           text(second[j]));
    }
}).change(); // Trigger once to add options at load of first choice

Also note that if you want to apply an instance method to an array, you need to pass the function as:

call_user_func_array(array($instance, "MethodName"), $myArgs);

Try wrapping your dates in single quotes, like this:

'15-6-2005'

It should be able to parse the date this way.

To get the value equivalent to your C cast, just bitwise and with the appropriate mask. e.g. if unsigned long is 32 bit:

>>> i = -6884376
>>> i & 0xffffffff
4288082920

or if it is 64 bit:

>>> i & 0xffffffffffffffff
18446744073702667240

Do be aware though that although that gives you the value you would have in C, it is still a signed value, so any subsequent calculations may give a negative result and you'll have to continue to apply the mask to simulate a 32 or 64 bit calculation.

This works because although Python looks like it stores all numbers as sign and magnitude, the bitwise operations are defined as working on two's complement values. C stores integers in twos complement but with a fixed number of bits. Python bitwise operators act on twos complement values but as though they had an infinite number of bits: for positive numbers they extend leftwards to infinity with zeros, but negative numbers extend left with ones. The & operator will change that leftward string of ones into zeros and leave you with just the bits that would have fit into the C value.

Displaying the values in hex may make this clearer (and I rewrote to string of f's as an expression to show we are interested in either 32 or 64 bits):

>>> hex(i)
'-0x690c18'
>>> hex (i & ((1 << 32) - 1))
'0xff96f3e8'
>>> hex (i & ((1 << 64) - 1)
'0xffffffffff96f3e8L'

For a 32 bit value in C, positive numbers go up to 2147483647 (0x7fffffff), and negative numbers have the top bit set going from -1 (0xffffffff) down to -2147483648 (0x80000000). For values that fit entirely in the mask, we can reverse the process in Python by using a smaller mask to remove the sign bit and then subtracting the sign bit:

>>> u = i & ((1 << 32) - 1)
>>> (u & ((1 << 31) - 1)) - (u & (1 << 31))
-6884376

Or for the 64 bit version:

>>> u = 18446744073702667240
>>> (u & ((1 << 63) - 1)) - (u & (1 << 63))
-6884376

This inverse process will leave the value unchanged if the sign bit is 0, but obviously it isn't a true inverse because if you started with a value that wouldn't fit within the mask size then those bits are gone.

The simplest solution would be (using 'upstream' as the remote name referencing the original repo forked):

git remote add upstream /url/to/original/repo
git fetch upstream
git checkout master
git reset --hard upstream/master  
git push origin master --force 

(Similar to this GitHub page, section "What should I do if I’m in a bad situation?")

Be aware that you can lose changes done on the master branch (both locally, because of the reset --hard, and on the remote side, because of the push --force).

An alternative would be, if you want to preserve your commits on master, to replay those commits on top of the current upstream/master.
Replace the reset part by a git rebase upstream/master. You will then still need to force push.
See also "What should I do if I’m in a bad situation?"

A more complete solution, backing up your current work (just in case) is detailed in "Cleanup git master branch and move some commit to new branch".

See also "Pull new updates from original GitHub repository into forked GitHub repository" for illustrating what "upstream" is.

Note: recent GitHub repos do protect the master branch against push --force.
So you will have to un-protect master first (see picture below), and then re-protect it after force-pushing).

Note: on GitHub specifically, there is now (February 2019) a shortcut to delete forked repos for pull requests that have been merged upstream.

The answer is given previous posts is valid. But not one answer is complete with respect to:

1. Changing the /etc/profile is not recommended simply because of the reason (as stated in /etc/profile):

• It's NOT a good idea to change this file unless you know what you are doing. It's much better to create a custom.sh shell script in /etc/profile.d/ to make custom changes to your environment, as this will prevent the need for merging in future updates.*

2. So as stated above create /etc/profile.d/custom.sh file for custom changes.

3. Now, to always keep updated with newer versions of Java being installed, never put the absolute path, instead use:

#if making jdk as java home

export JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")

OR

#if making jre as java home

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:/bin/java::")

4. And remember to have #! /bin/bash on the custom.sh file

I am using this for checking for key presses, can't get much simpler:

#!/usr/bin/python3
# -*- coding: UTF-8 -*-

import curses, time

def main(stdscr):
    """checking for keypress"""
    stdscr.nodelay(True)  # do not wait for input when calling getch
    return stdscr.getch()

while True:
    print("key:", curses.wrapper(main)) # prints: 'key: 97' for 'a' pressed
                                        # '-1' on no presses
    time.sleep(1)

While curses is not working on windows, there is a 'unicurses' version, supposedly working on Linux, Windows, Mac but I could not get this to work

Just because I like to question code. I propose that you can also make use of the ternary by doing something like this:

Example:

bool flipValue = false;
bool bShouldFlip = true;
flipValue = bShouldFlip ? !flipValue : flipValue;

Javascript sort of has the idea of 'truthiness' and 'falsiness'. If a variable has a value then, generally 9as you will see) it has 'truthiness' - null, or no value tends to 'falsiness'. The snippets below might help:

var temp1; 
if ( temp1 )...  // false

var temp2 = true;
if ( temp2 )...  // true

var temp3 = "";
if ( temp3 ).... // false

var temp4 = "hello world";
if ( temp4 )...  // true

Hopefully that helps?

Also, its worth checking out these videos from Douglas Crockford

You can do git push --force but be aware that you are rewriting history and anyone using the repo will have issue with this.

If you want to prevent this problem, don't use reset, but instead use git revert

Bulk imports seems to perform best if you can chunk your INSERT/UPDATE statements. A value of 10,000 or so has worked well for me on a table with only a few rows, YMMV...

@article = user.articles.build(:title => "MainTitle")
@article.save

Have you tried what is on the sample. I am new to this but here is the command: puppet --test --trace --debug. I hope this helps.

While it is true that there is no DROP ALL TABLES command you can use the following set of commands.

Note: These commands have the potential to corrupt your database, so make sure you have a backup

PRAGMA writable_schema = 1;
delete from sqlite_master where type in ('table', 'index', 'trigger');
PRAGMA writable_schema = 0;

you then want to recover the deleted space with

VACUUM;

and a good test to make sure everything is ok

PRAGMA INTEGRITY_CHECK;

Answer is really simple guys, in android if you want to convert hex color in to int, just use android Color class, example shown as below

this is for light gray color

Color.parseColor("#a8a8a8");

Thats it and you will get your result.

ToList will create a brand new list.

If the items in the list are value types, they will be directly updated, if they are reference types, any changes will be reflected back in the referenced objects.

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

For background, see the Understanding ASP.NET dynamic compilation article on MSDN.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

For anyone that finds this question looking for how to access custom properties in ASP.NET Core 2.1 - it's much easier: You'll have a UserManager, e.g. in _LoginPartial.cshtml, and then you can simply do (assuming "ScreenName" is a property that you have added to your own AppUser which inherits from IdentityUser):

@using Microsoft.AspNetCore.Identity

@using <namespaceWhereYouHaveYourAppUser>

@inject SignInManager<AppUser> SignInManager
@inject UserManager<AppUser> UserManager

@if (SignInManager.IsSignedIn(User)) {
    <form asp-area="Identity" asp-page="/Account/Logout" asp-route-returnUrl="@Url.Action("Index", "Home", new { area = "" })" 
          method="post" id="logoutForm" 
          class="form-inline my-2 my-lg-0">

        <ul class="nav navbar-nav ml-auto">
            <li class="nav-item">
                <a class="nav-link" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">
                    Hello @((await UserManager.GetUserAsync(User)).ScreenName)!
                    <!-- Original code, shows Email-Address: @UserManager.GetUserName(User)! -->
                </a>
            </li>
            <li class="nav-item">
                <button type="submit" class="btn btn-link nav-item navbar-link nav-link">Logout</button>
            </li>
        </ul>

    </form>
} else {
    <ul class="navbar-nav ml-auto">
        <li class="nav-item"><a class="nav-link" asp-area="Identity" asp-page="/Account/Register">Register</a></li>
        <li class="nav-item"><a class="nav-link" asp-area="Identity" asp-page="/Account/Login">Login</a></li>
    </ul>
}

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

There is an input:focus as there is a textarea:focus

input:focus { 
    outline: none !important;
    border-color: #719ECE;
    box-shadow: 0 0 10px #719ECE;
}
textarea:focus { 
    outline: none !important;
    border-color: #719ECE;
    box-shadow: 0 0 10px #719ECE;
}

Code:

List<String> list = new ArrayList<String>();

list.add("a");

JSONArray array = new JSONArray();

for (int i = 0; i < list.size(); i++) {
    array.put(list.get(i));
}
JSONObject obj = new JSONObject();

try {
    obj.put("result", array);
} catch (JSONException e) {
    e.printStackTrace();
}

string strHeader = Request.Headers["XYZComponent"]
bool bHeader = Boolean.TryParse(strHeader, out bHeader ) && bHeader;

if "true" than true
if "false" or anything else ("fooBar") than false

or

string strHeader = Request.Headers["XYZComponent"]
bool b;
bool? bHeader = Boolean.TryParse(strHeader, out b) ? b : default(bool?);

if "true" than true
if "false" than false
else ("fooBar") than null

The Object.entries() method has been specified in ES2017 (and is supported in all modern browsers):

for (const [ key, value ] of Object.entries(dictionary)) {
    // do something with `key` and `value`
}

Explanation:

• Object.entries() takes an object like { a: 1, b: 2, c: 3 } and turns it into an array of key-value pairs: [ [ 'a', 1 ], [ 'b', 2 ], [ 'c', 3 ] ].

• With for ... of we can loop over the entries of the so created array.

• Since we are guaranteed that each of the so iterated array items is itself a two-entry array, we can use destructuring to directly assign variables key and value to its first and second item.

It is very simple to do that, First create a copy of your table that your want keep the log for For example you have Table dbo.SalesOrder with columns SalesOrderId, FirstName,LastName, LastModified

Your Version archieve table should be dbo.SalesOrderVersionArchieve with columns SalesOrderVersionArhieveId, SalesOrderId, FirstName,LastName, LastModified

Here is the how you will set up a trigger on SalesOrder table

USE [YOURDB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:      Karan Dhanu
-- Create date: <Create Date,,>
-- Description: <Description,,>
-- =============================================
CREATE TRIGGER dbo.[CreateVersionArchiveRow]
   ON  dbo.[SalesOrder]
  AFTER Update
AS 
BEGIN

    SET NOCOUNT ON;
INSERT INTO dbo.SalesOrderVersionArchive

   SELECT *
   FROM deleted;

END

Now if you make any changes in saleOrder table it will show you the change in VersionArchieve table

in laravel-8 default remove namespace prefix so you can set old way in laravel-7 like:

in RouteServiceProvider.php add this variable

protected $namespace = 'App\Http\Controllers';

and update boot method

public function boot()
{
       $this->configureRateLimiting();

       $this->routes(function () {
            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/web.php'));

            Route::prefix('api')
                ->middleware('api')
                ->namespace($this->namespace)
                ->group(base_path('routes/api.php'));
        });
}

This does not have anything to do with character encodings such as UTF-8 or ASCII. The string you have there is URL encoded. This kind of encoding is something entirely different than character encoding.

Try something like this:

try {
    String result = java.net.URLDecoder.decode(url, StandardCharsets.UTF_8.name());
} catch (UnsupportedEncodingException e) {
    // not going to happen - value came from JDK's own StandardCharsets
}

Java 10 added direct support for Charset to the API, meaning there's no need to catch UnsupportedEncodingException:

String result = java.net.URLDecoder.decode(url, StandardCharsets.UTF_8);

Note that a character encoding (such as UTF-8 or ASCII) is what determines the mapping of characters to raw bytes. For a good intro to character encodings, see this article.

This is thrown when

... the peer was not able to identify itself (for example; no certificate, the particular cipher suite being used does not support authentication, or no peer authentication was established during SSL handshaking) this exception is thrown.

Probably the cause of this exception (where is the stacktrace) will show you why this exception is thrown. Most likely the default keystore shipped with Java does not contain (and trust) the root certificate of the TTP that is being used.

The answer is to retrieve the root certificate (e.g. from your browsers SSL connection), import it into the cacerts file and trust it using keytool which is shipped by the Java JDK. Otherwise you will have to assign another trust store programmatically.

Delete and Reset the prefix

$ npm config delete prefix 
$ npm config set prefix $NVM_DIR/versions/node/v6.11.1

Note: Change the version number with the one indicated in the error message.

nvm is not compatible with the npm config "prefix" option: currently set to "/usr/local" Run "npm config delete prefix" or "nvm use --delete-prefix v6.11.1 --silent" to unset it.

Use string concatenation. Try this:

$('div[imageId="'+imageN +'"]').each(function() {
    $(this);   
});

const firstDayOfYear = new Date(today.getFullYear(), 0, 1);

// Explicitly convert Date to Number
const pastDaysOfYear = ( Number(today) - Number(firstDayOfYear) );

Don't grant control to the user, it's totally unnecessay. Select permission on the database is enough. After you have created the login and the user on master (see above answers):

use YourDatabase
go
create user [YourDomain\YourUser] for login [YourDomain\YourUser] with default_schema=[dbo]
go
alter role [db_datareader] add member [YourDomain\YourUser]
go

In some cases, which others have highlighted, guaranteed arrival of packets isn't important, and hence using UDP is fine. There are other cases where UDP is preferable to TCP.

One unique case where you would want to use UDP instead of TCP is where you are tunneling TCP over another protocol (e.g. tunnels, virtual networks, etc.). If you tunnel TCP over TCP, the congestion controls of each will interfere with each other. Hence one generally prefers to tunnel TCP over UDP (or some other stateless protocol). See TechRepublic article: Understanding TCP Over TCP: Effects of TCP Tunneling on End-to-End Throughput and Latency.

If you are connecting a remote mysql server from your local machine using java see the below steps. Error : "java.sql.SQLException: Access denied for user 'xxxxx'@'101.123.163.141' (using password: YES) "

for remote access may be cpanel or others grant the remote access for your local ip address.

In the above error message: "101.123.163.141" is my local machine ip. So First we have to give remote access in the Cpanel-> Remote MySQL®. Then run your application to connect.

Class.forName("com.mysql.jdbc.Driver");  
Connection con=DriverManager.getConnection(  
    "jdbc:mysql://www.xyz.com/abc","def","ghi");  
//here abc is database name, def is username and ghi        
Statement stmt=con.createStatement();  
ResultSet rs=stmt.executeQuery("select * from employee");  
    while(rs.next())  
        System.out.println(rs.getInt(1)+" "+rs.getString(2)+"  
                          "+rs.getString(3));  
con.close();    

Hope it will resolve your issue.

You seem to be aware already, but I'll just restate it anyway; It's a bad sign, if you need to test protected methods. The aim of a unit test, is to test the interface of a class, and protected methods are implementation details. That said, there are cases where it makes sense. If you use inheritance, you can see a superclass as providing an interface for the subclass. So here, you would have to test the protected method (But never a private one). The solution to this, is to create a subclass for testing purpose, and use this to expose the methods. Eg.:

class Foo {
  protected function stuff() {
    // secret stuff, you want to test
  }
}

class SubFoo extends Foo {
  public function exposedStuff() {
    return $this->stuff();
  }
}

Note that you can always replace inheritance with composition. When testing code, it's usually a lot easier to deal with code that uses this pattern, so you may want to consider that option.

For selenium, an alert is the one which raised using javascript e.g.

 javascript:alert();

There is one basic check to verify whether your alert is actually a javascript alert or just a div-based box for displaying some message. If its a javascript alert, you wont be able to see it on screen while running the selenium script.

If you are able to see it, then you need to get the locator of the ok button of the alert and use selenium.click(locator) to dismiss the alert. Can help you better if you can provide more context:

1. IDE or RC?
2. HTML code of the alert
3. your selenium script.

I came across this issue myself. I had the need to conditionally validate parts of a form while the form was being constructed based on steps (i.e. certain inputs were dynamically appended during runtime). As a result, sometimes a select dropdown would need validation, and sometimes it would not. However, by the end of the ordeal, it needed to be validated. As a result, I needed a robust method which was not a workaround. I consulted the source code for jquery.validate.

Here is what I came up with:

function clearValidation(formElement){
 //Internal $.validator is exposed through $(form).validate()
 var validator = $(formElement).validate();
 //Iterate through named elements inside of the form, and mark them as error free
 $('[name]',formElement).each(function(){
   validator.successList.push(this);//mark as error free
   validator.showErrors();//remove error messages if present
 });
 validator.resetForm();//remove error class on name elements and clear history
 validator.reset();//remove all error and success data
}
//used
var myForm = document.getElementById("myFormId");
clearValidation(myForm);

$.fn.clearValidation = function(){var v = $(this).validate();$('[name]',this).each(function(){v.successList.push(this);v.showErrors();});v.resetForm();v.reset();};
//used:
$("#formId").clearValidation();

You can do

var arr = _.values(obj);

For documentation see here.

(In reply to the "has the situation improved?" part of the question):

Unfortunately, not really. Illustrator's support for SVG has always been a little shaky, and, having mucked around in Illustrator's internals, I doubt we'll see much improvement as far as Illustrator is concerned.

If you're looking for DOM-style access to an Illustrator document, you might want to check out Hanpuku (Disclosure #1: I'm the author. Disclosure #2: It's research code, meaning there are bugs aplenty, and future support is unlikely).

With Hanpuku, you could do something like:

1. Select the path of interest in Illustrator
2. Click the "To D3" button

3. In the script editor, type:

   selection.attr('d', 'M 0 0 L 20 134 L 233 24 Z');

4. Click run

5. If the change is as expected, click "To Illustrator" to apply the changes to the document

Granted, this approach doesn't expose the original path string. If you follow the instructions toward the end of the plugin's welcome page, it's possible to edit the Illustrator document with Chrome's developer tools, but there will be lots of ugly engineering exposed everywhere (the SVG DOM that mirrors the Illustrator document is buried inside an iframe deep in the extension—changing the DOM with Chrome's tools and clicking "To Illustrator" should still work, but you will likely encounter lots of problems).

TL;DR: Illustrator uses an internal model that's pretty different from SVG in a lot of ways, meaning that when you iterate between the two, currently, your only choice is to use the subset of features that both support in the same way.

I have wondered about this in the past and came to the conclusion that it was not actually a valid test case for my code. I don't think your application code can actually tell the difference between somebody declining notifications the first time or later disabling it from the iPhone notification settings. It is true that the user experience is different but that is hidden inside the call to registerForRemoteNotificationTypes.

Calling unregisterForRemoteNotifications does not completely remove the application from the notifications settings - though it does remove the contents of the settings for that application. So this still will not cause the dialog to be presented a second time to the user the next time the app runs (at least not on v3.1.3 that I am currently testing with). But as I say above you probably should not be worrying about that.

In Python you can just use the new-line character, i.e. \n

Instead of using cat and I/O redirection it might be useful to use tee instead:

tee newfile <<EOF
line 1
line 2
line 3
EOF

It's more concise, plus unlike the redirect operator it can be combined with sudo if you need to write to files with root permissions.

I've encountered this error when my Transaction is nested within another. Is it possible that the stored procedure declares its own transaction or that the calling function declares one?

I build this solution, reformulate does not take care if variable names have white spaces.

add_backticks = function(x) {
    paste0("`", x, "`")
}

x_lm_formula = function(x) {
    paste(add_backticks(x), collapse = " + ")
}

build_lm_formula = function(x, y){
    if (length(y)>1){
        stop("y needs to be just one variable")
    }
    as.formula(        
        paste0("`",y,"`", " ~ ", x_lm_formula(x))
    )
}

# Example
df <- data.frame(
    y = c(1,4,6), 
    x1 = c(4,-1,3), 
    x2 = c(3,9,8), 
    x3 = c(4,-4,-2)
    )

# Model Specification
columns = colnames(df)
y_cols = columns[1]
x_cols = columns[2:length(columns)]
formula = build_lm_formula(x_cols, y_cols)
formula
# output
# "`y` ~ `x1` + `x2` + `x3`"

# Run Model
lm(formula = formula, data = df)
# output
Call:
    lm(formula = formula, data = df)

You only have one row to serialize. Try something like this :

List<results> resultRows = new List<results>

resultRows.Add(new results{id = 1, value="ABC", info="ABC"});
resultRows.Add(new results{id = 2, value="XYZ", info="XYZ"});

string json = JavaScriptSerializer.Serialize(new { results = resultRows});

• Edit to match OP's original json output

** Edit 2 : sorry, but I missed that he was using JSON.NET. Using the JavaScriptSerializer the above code produces this result :

{"results":[{"id":1,"value":"ABC","info":"ABC"},{"id":2,"value":"XYZ","info":"XYZ"}]}

I made an autocomplete directive and uploaded it to GitHub. It should also be able to handle data from an HTTP-Request.

Here's the demo: http://justgoscha.github.io/allmighty-autocomplete/ And here the documentation and repository: https://github.com/JustGoscha/allmighty-autocomplete

So basically you have to return a promise when you want to get data from an HTTP request, that gets resolved when the data is loaded. Therefore you have to inject the $qservice/directive/controller where you issue your HTTP Request.

Example:

function getMyHttpData(){
  var deferred = $q.defer();
  $http.jsonp(request).success(function(data){
    // the promise gets resolved with the data from HTTP
    deferred.resolve(data);
  });
  // return the promise
  return deferred.promise;
}

I hope this helps.

Shortcut by creating AppendString (AS) macro ...

#define AS(A,B)    [(A) stringByAppendingString:(B)]

NSString *myString = @"This";

NSString *test = AS(myString,@" is just a test");

Note:

If using a macro, of course just do it with variadic arguments, see EthanB's answer.

Thanks, I didn't have the idea of an UPDATE with INNER JOIN.

In the original query, the mistake was to name the subquery, which must return a value and can't therefore be aliased.

UPDATE Competition
SET Competition.NumberOfTeams =
(SELECT count(*) -- no column alias
  FROM PicksPoints
  WHERE UserCompetitionID is not NULL
  -- put the join condition INSIDE the subquery :
  AND CompetitionID =  Competition.CompetitionID
  group by CompetitionID
) -- no table alias

should do the trick for every record of Competition.

To be noticed :

The effect is NOT EXACTLY the same as the query proposed by mellamokb, which won't update Competition records with no corresponding PickPoints.

Since SELECT id, COUNT(*) GROUP BY id will only count for existing values of ids,

whereas a SELECT COUNT(*) will always return a value, being 0 if no records are selected.

This may, or may not, be a problem for you.

0-aware version of mellamokb query would be :

Update Competition as C
LEFT join (
  select CompetitionId, count(*) as NumberOfTeams
  from PicksPoints as p
  where UserCompetitionID is not NULL
  group by CompetitionID
) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = IFNULL(A.NumberOfTeams, 0)

In other words, if no corresponding PickPoints are found, set Competition.NumberOfTeams to zero.

I couldn't figure out what exactly you meant by byte String, but here are some conversions from byte to String and vice versa, of course there is a lot more on the official documentations

Integer intValue = 149;

The corresponding byte value is:

Byte byteValue = intValue.byteValue(); // this will convert the rightmost byte of the intValue to byte, because Byte is an 8 bit object and Integer is at least 16 bit, and it will give you a signed number in this case -107

get the integer value back from a Byte variable:

Integer anInt = byteValue.intValue(); // This will convert the byteValue variable to a signed Integer

From Byte and Integer to hex String:
This is the way I do it:

Integer anInt = 149
Byte aByte = anInt.byteValue();

String hexFromInt = "".format("0x%x", anInt); // This will output 0x95
String hexFromByte = "".format("0x%x", aByte); // This will output 0x95

Converting an array of bytes to a hex string:
As far as I know there is no simple function to convert all the elements inside an array of some Object to elements of another Object, So you have to do it yourself. You can use the following functions:

From byte[] to String:

    public static String byteArrayToHexString(byte[] byteArray){
        String hexString = "";

        for(int i = 0; i < byteArray.length; i++){
            String thisByte = "".format("%x", byteArray[i]);
            hexString += thisByte;
        }

        return hexString;
    }

And from hex string to byte[]:

public static byte[] hexStringToByteArray(String hexString){
    byte[] bytes = new byte[hexString.length() / 2];

    for(int i = 0; i < hexString.length(); i += 2){
        String sub = hexString.substring(i, i + 2);
        Integer intVal = Integer.parseInt(sub, 16);
        bytes[i / 2] = intVal.byteValue();
        String hex = "".format("0x%x", bytes[i / 2]);
    }

    return bytes;
}  

It is too late but I hope this could help some others ;)

If all you need is a simple countdown timer, this is a good alternative instead of installing a package. Happy coding!

countDownTimer() async {
 int timerCount;
 for (int x = 5; x > 0; x--) {
   await Future.delayed(Duration(seconds: 1)).then((_) {
     setState(() {
       timerCount -= 1;
    });
  });
 }
}

If Subversion is already installed ,there's no need to reinstall it with the command line client tools.
Simply Goto

Start(Rightclick) ->App and Feature ->TortoiseSvn->Modify->Install command line client tools.   

string[] lines = File.ReadAllLines("sample.txt"); List<string> list1 = new List<string>(); List<string> list2 = new List<string>();  foreach (var line in lines) {     string[] values = line.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);     list1.Add(values[0]);     list2.Add(values[1]);  } 

Make a div and use your image ( png with transparent background ) as the background of the div, then you can apply any text within that div to hover over the button. Something like this:

<div class="button" onclick="yourbuttonclickfunction();" >
Your Button Label Here
</div>

CSS:

.button {
height:20px;
width:40px;
background: url("yourimage.png");
}

Use replace()

 s = s.replace("'", "\\'"); 

output:

You\'ll be totally awesome, I\'m really terrible

Just set the value for scaleStartValue in your options.

var options = {
   // ....
   scaleStartValue: 0,

You can just use the return value of require:

if(!require(somepackage)){
    install.packages("somepackage")
    library(somepackage)
}

I use library after the install because it will throw an exception if the install wasn't successful or the package can't be loaded for some other reason. You make this more robust and reuseable:

dynamic_require <- function(package){
  if(eval(parse(text=paste("require(",package,")")))) return True

  install.packages(package)
  return eval(parse(text=paste("require(",package,")")))
}

The downside to this method is that you have to pass the package name in quotes, which you don't do for the real require.

You must define the class before creating an instance of the class. Move the invocation of Something to the end of the script.

You can try to put the cart before the horse and invoke procedures before they are defined, but it will be an ugly hack and you will have to roll your own as defined here:

Make function definition in a python file order independent

In ECMAScript proposal Stage 1 there is a suggestion to add an array property that will return the last element: proposal-array-last.

Syntax:

arr.lastItem // get last item
arr.lastItem = 'value' // set last item

arr.lastIndex // get last index

You can use polyfill.

You can use:

$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);

Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.

I make a wild assumption that you really have layout as:

<ul  class="tabs">
  <li id="tabone">one</li>
  <li id="tabtwo">two</li>
</ul>

IF that assumption is correct, you simply use the ID to select the "tab"

$('#tabone').css("display","none");

EDIT: select the tab on your layout:

var index = $('.tabs ul').index($('#tabone')); 
$('.tabs ul').tabs('select', index); 

Where are you configuring your authenticated URL pattern(s)? I only see one uri in your code.

Do you have multiple configure(HttpSecurity) methods or just one? It looks like you need all your URIs in the one method.

I have a site which requires authentication to access everything so I want to protect /*. However in order to authenticate I obviously want to not protect /login. I also have static assets I'd like to allow access to (so I can make the login page pretty) and a healthcheck page that shouldn't require auth.

In addition I have a resource, /admin, which requires higher privledges than the rest of the site.

The following is working for me.

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.authorizeRequests()
        .antMatchers("/login**").permitAll()
        .antMatchers("/healthcheck**").permitAll()
        .antMatchers("/static/**").permitAll()
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .and()
            .formLogin().loginPage("/login").failureUrl("/login?error")
                .usernameParameter("username").passwordParameter("password")
        .and()
            .logout().logoutSuccessUrl("/login?logout")
        .and()
            .exceptionHandling().accessDeniedPage("/403")
        .and()
            .csrf();

}

NOTE: This is a first match wins so you may need to play with the order. For example, I originally had /** first:

        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .antMatchers("/login**").permitAll()
        .antMatchers("/healthcheck**").permitAll()

Which caused the site to continually redirect all requests for /login back to /login. Likewise I had /admin/** last:

        .antMatchers("/**").access("hasRole('ROLE_USER')")
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")

Which resulted in my unprivledged test user "guest" having access to the admin interface (yikes!)

You can declare local variables in MySQL triggers, with the DECLARE syntax.

Here's an example:

DROP TABLE IF EXISTS foo;
CREATE TABLE FOO (
  i SERIAL PRIMARY KEY
);

DELIMITER //
DROP TRIGGER IF EXISTS bar //

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = NEW.i;
  SET @a = x; -- set user variable outside trigger
END//

DELIMITER ;

SET @a = 0;

SELECT @a; -- returns 0

INSERT INTO foo () VALUES ();

SELECT @a; -- returns 1, the value it got during the trigger

When you assign a value to a variable, you must ensure that the query returns only a single value, not a set of rows or a set of columns. For instance, if your query returns a single value in practice, it's okay but as soon as it returns more than one row, you get "ERROR 1242: Subquery returns more than 1 row".

You can use LIMIT or MAX() to make sure that the local variable is set to a single value.

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT age FROM users WHERE name = 'Bill'); 
  -- ERROR 1242 if more than one row with 'Bill'
END//

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT MAX(age) FROM users WHERE name = 'Bill');
  -- OK even when more than one row with 'Bill'
END//

Use a custom Listview.

You can also customize how row looks by having a custom background. activity_main.xml

Don't use this on large sites though. The :before pseudo-element is horrible in terms of performance.

In addition to what other have said, you may also be interested to know that what in does is to call the list.__contains__ method, that you can define on any class you write and can get extremely handy to use python at his full extent.  

A dumb use may be:

>>> class ContainsEverything:
    def __init__(self):
        return None
    def __contains__(self, *elem, **k):
        return True


>>> a = ContainsEverything()
>>> 3 in a
True
>>> a in a
True
>>> False in a
True
>>> False not in a
False
>>>         

If you have multiple versions of a package / module, you need to be using virtualenv (emphasis mine):

virtualenv is a tool to create isolated Python environments.

The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.

Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application.

Also, what if you can’t install packages into the global site-packages directory? For instance, on a shared host.

In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn’t share libraries with other virtualenv environments (and optionally doesn’t access the globally installed libraries either).

That's why people consider insert(0, to be wrong -- it's an incomplete, stopgap solution to the problem of managing multiple environments.

I don't think I can improve on these answers as I've used them all, but my preference is declaring a constant and using that as it can be a real pain if you have a long string and try to accommodate with the correct number of quotes and make a mistake. ;)

You can try:

node.offsetTop - window.scrollY

It works on Opera with viewport meta tag defined.

Here I'm basically wrapping a button in a link. The advantage is that you can post to different action methods in the same form.

<a href="Controller/ActionMethod">
    <input type="button" value="Click Me" />
</a>

Adding parameters:

<a href="Controller/ActionMethod?userName=ted">
    <input type="button" value="Click Me" />
</a>

Adding parameters from a non-enumerated Model:

<a href="Controller/[email protected]">
    <input type="button" value="Click Me" />
</a>

You can do the same for an enumerated Model too. You would just have to reference a single entity first. Happy Coding!

The following example demonstrates how to POST a JSON via WebClient.UploadString Method:

var vm = new { k = "1", a = "2", c = "3", v=  "4" };
using (var client = new WebClient())
{
   var dataString = JsonConvert.SerializeObject(vm);
   client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
   client.UploadString(new Uri("http://www.contoso.com/1.0/service/action"), "POST", dataString);
}

Prerequisites: Json.NET library

Since PostgreSQL 9.4 there's the FILTER clause, which allows for a very concise query to count the true values:

select count(*) filter (where myCol)
from tbl;

The above query is a bad example in that a simple WHERE clause would suffice, and is for demonstrating the syntax only. Where the FILTER clause shines is that it is easy to combine with other aggregates:

select count(*), -- all
       count(myCol), -- non null
       count(*) filter (where myCol) -- true
from tbl;

The clause is especially handy for aggregates on a column that uses another column as the predicate, while allowing to fetch differently filtered aggregates in a single query:

select count(*),
       sum(otherCol) filter (where myCol)
from tbl;

Use the rename script this way:

$ rename 's/^/PRE_/' *

There are no problems with metacharacters or whitespace in filenames.

I realize this is a two year old question, but I still found it useful. I ended up using the sample code provided by Fudgey but with a minor mod. Saved me some time, thanks!

jQuery.fn.dataTableExt.oSort['us_date-asc']  = function(a,b) { 
  var x = new Date($(a).text()),
  y = new Date($(b).text());
  return ((x < y) ? -1 : ((x > y) ?  1 : 0)); 
}; 

jQuery.fn.dataTableExt.oSort['us_date-desc'] = function(a,b) { 
  var x = new Date($(a).text()),
  y = new Date($(b).text());
  return ((x < y) ? 1 : ((x > y) ?  -1 : 0)); 
}; 

Another example using COALESCE. http://sqlmag.com/t-sql/coalesce-vs-isnull

SELECT (COALESCE(SUM(val1),0) + COALESCE(SUM(val2), 0)
+ COALESCE(SUM(val3), 0) + COALESCE(SUM(val4), 0)) AS 'TOTAL'
FROM Emp

To just get a date you can cast it

cast(user.registration as date)

and to get a specific format use date_format

date_format(registration, '%Y-%m-%d')

None of the video settings posted above worked in modern browsers I tested (like Firefox) using the embed or object elements in HTML5. For video or audio elements they did stop autoplay. For embed and object they did not.

I tested this using the embed and object elements using several different media types as well as HTML attributes (like autostart and autoplay). These videos always played regardless of any combination of settings in several browsers. Again, this was not an issue using the newer HTML5 video or audio elements, just when using embed and object.

It turns out the new browser settings for video "autoplay" have changed. Firefox will now ignore the autoplay attributes on these tags and play videos anyway unless you explicitly set to "block audio and video" autoplay in your browser settings.

To do this in Firefox I have posted the settings below:

1. Open up your Firefox Browser, click the menu button, and select "Options"
2. Select the "Privacy & Security" panel and scroll down to the "Permissions" section
3. Find "Autoplay" and click the "Settings" button. In the dropdown change it to block audio and video. The default is just audio.

Your videos will NOT autoplay now when displaying videos in web pages using object or embed elements.

I know this is an old thread but I ended up here with the same issue.

I solved it by comparing the dependencies classpath in the build.gradle script(Project) to the installed version.

The error message was pointing to the following folder

C:\Program Files\Android\android-studio3 preview\gradle\m2repository\com\android\tools\build\gradle

It turned out that the alpha2 version was installed but the classpath was still pointing to alpaha1. A simple change to the classpath ('com.android.tools.build:gradle:3.0.0-alpha2') was all that was needed.

This may not help everyone, but I do hope it help most people out.

Ok, the way I see it you have 3 options.

1: If you simply wish to check whether the number is an integer, and don't care about converting it, but simply wish to keep it as a string and don't care about potential overflows, checking whether it matches a regex for an integer would be ideal here.

2: You can use boost::lexical_cast and then catch a potential boost::bad_lexical_cast exception to see if the conversion failed. This would work well if you can use boost and if failing the conversion is an exceptional condition.

3: Roll your own function similar to lexical_cast that checks the conversion and returns true/false depending on whether it's successful or not. This would work in case 1 & 2 doesn't fit your requirements.

• Rowids of all the tables in the FROM list must appear in the SELECT list of the query.

This means that your statement will need to look something like this:

CREATE MATERIALIZED VIEW MV_Test
  NOLOGGING
  CACHE
  BUILD IMMEDIATE 
  REFRESH FAST ON COMMIT 
  AS
    SELECT V.*, P.*, V.ROWID as V_ROWID, P.ROWID as P_ROWID 
    FROM TPM_PROJECTVERSION V,
         TPM_PROJECT P 
    WHERE P.PROJECTID = V.PROJECTID

Another key aspect to note is that your materialized view logs must be created as with rowid.

Below is a functional test scenario:

CREATE TABLE foo(foo NUMBER, CONSTRAINT foo_pk PRIMARY KEY(foo));

CREATE MATERIALIZED VIEW LOG ON foo WITH ROWID;

CREATE TABLE bar(foo NUMBER, bar NUMBER, CONSTRAINT bar_pk PRIMARY KEY(foo, bar));

CREATE MATERIALIZED VIEW LOG ON bar WITH ROWID;

CREATE MATERIALIZED VIEW foo_bar
  NOLOGGING
  CACHE
  BUILD IMMEDIATE
  REFRESH FAST ON COMMIT  AS SELECT foo.foo, 
                                    bar.bar, 
                                    foo.ROWID AS foo_rowid, 
                                    bar.ROWID AS bar_rowid 
                               FROM foo, bar
                              WHERE foo.foo = bar.foo;

You can use "struct" in C++ if you are writing a library whose internals are C++ but the API can be called by either C or C++ code. You simply make a single header that contains structs and global API functions that you expose to both C and C++ code as this:

// C access Header to a C++ library
#ifdef __cpp
extern "C" {
#endif

// Put your C struct's here
struct foo
{
    ...
};
// NOTE: the typedef is used because C does not automatically generate
// a typedef with the same name as a struct like C++.
typedef struct foo foo;

// Put your C API functions here
void bar(foo *fun);

#ifdef __cpp
}
#endif

Then you can write a function bar() in a C++ file using C++ code and make it callable from C and the two worlds can share data through the declared struct's. There are other caveats of course when mixing C and C++ but this is a simplified example.

There is (at least) one wayhack to get truly dynamic height without javascript: insert the menu twice:

• Once in the flow to position the following elements, and
• once fixed for the desired visual effect.

<div id="the-menu-container">_x000D_
    <nav class="position-static">...</nav>_x000D_
    <nav class="position-fixed">...</nav>_x000D_
</div>

Depending on the rest of your site, you might have to tweak the z-index styles of the <nav> elements.

Using the scroll-behavior CSS property:

(which is supported in modern browsers but not Edge):

a {
  display: inline-block;
  padding: 5px 7%;
  text-decoration: none;
}

nav, section {
  display: block;
  margin: 0 auto;
  text-align: center;
}

nav {
  width: 350px;
  padding: 5px;
}

section {
  width: 350px;
  height: 130px;
  overflow-y: scroll;
  border: 1px solid black;
  font-size: 0; 
  scroll-behavior: smooth;    /* <----- THE SECRET ---- */
}

section div{
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100%;
  font-size: 8vw;
}

<nav>
  <a href="#page-1">1</a>
  <a href="#page-2">2</a>
  <a href="#page-3">3</a>
</nav>
<section>
  <div id="page-1">1</div>
  <div id="page-2">2</div>
  <div id="page-3">3</div>
</section>

You can use this Firefox addon to download all files in HTTP Directory.

https://addons.mozilla.org/en-US/firefox/addon/http-directory-downloader/

You can do this:

CSS:

#container {
    height:175px;
}

#container h3{
    position:absolute;
    bottom:0;
    left:0;
}

Then in HTML:

<div class="row">
    <div class="col-sm-6">
        <img src="//placehold.it/600x300" alt="Logo" />
    </div>
    <div id="container" class="col-sm-6">
        <h3>Some Text</h3>
    </div>
</div>

EDIT: add the <

when all else fails I just

<center> content </center>

I know its not "up to standards" any more, but if it works it works

You can use:

try:
   # get your models
except ObjectDoesNotExist:
   # do something

If you want to compare to a string literal you need to put it in (single) quotes:

<xsl:if test="Count != 'N/A'">

Use next:

(1..10).each do |a|
  next if a.even?
  puts a
end

prints:

1
3   
5
7
9

For additional coolness check out also redo and retry.

Works also for friends like times, upto, downto, each_with_index, select, map and other iterators (and more generally blocks).

For more info see http://ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html#UL.

echo "<a href='index.php'>Index Page</a>";

if you wanna use html tag like anchor tag you have to put in echo

In pandas 0.16.1+ you can drop columns only if they exist per the solution posted by @eiTanLaVi. Prior to that version, you can achieve the same result via a conditional list comprehension:

df.drop([col for col in ['col_name_1','col_name_2',...,'col_name_N'] if col in df], 
        axis=1, inplace=True)

You are asking about the && operator, not the if statement.

&& short-circuits, meaning that if while working it meets a condition which results in only one answer, it will stop working and use that answer.

So, 0 && x will execute 0, then terminate because there is no way for the expression to evaluate non-zero regardless of what is the second parameter to &&.

Eduardo Molteni had a great answer:

• SQL Server Automated Backups

Using Windows Scheduled Tasks:

In the batch file

"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\SQLCMD.EXE" -S 
(local)\SQLExpress -i D:\dbbackups\SQLExpressBackups.sql

In SQLExpressBackups.sql

BACKUP DATABASE MyDataBase1 TO  DISK = N'D:\DBbackups\MyDataBase1.bak' 
WITH NOFORMAT, INIT,  NAME = N'MyDataBase1 Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

BACKUP DATABASE MyDataBase2 TO  DISK = N'D:\DBbackups\MyDataBase2.bak' 
WITH NOFORMAT, INIT,  NAME = N'MyDataBase2 Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

GO

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO read_write ;
GRANT ALL                            ON ALL TABLES IN SCHEMA public TO admin ;

if you do it from unix command (apart from PGAdmin) dont forget to pass the DB as a parameter. otherwise this extension will not be enabled when executing requests on this DB

psql -d -c "create EXTENSION pgcrypto;"

This article helped me to make the right choices eventually since mac 10.14.6 by default came with python 2.7* and I had to upgrade to 3.7.*

brew install python3
brew update && brew upgrade python
alias python=/usr/local/bin/python3

Referred The right and wrong way to set Python 3 as default on a Mac article

This is very simple.

1. Unit testing: This is the testing actually done by developers that have coding knowledge. This testing is done at the coding phase and it is a part of white box testing. When a software comes for development, it is developed into the piece of code or slices of code known as a unit. And individual testing of these units called unit testing done by developers to find out some kind of human mistakes like missing of statement coverage etc..

2. Functional testing: This testing is done at testing (QA) phase and it is a part of black box testing. The actual execution of the previously written test cases. This testing is actually done by testers, they find the actual result of any functionality in the site and compare this result to the expected result. If they found any disparity then this is a bug.

3. Acceptance testing: know as UAT. And this actually done by the tester as well as developers, management team, author, writers, and all who are involved in this project. To ensure the project is finally ready to be delivered with bugs free.

4. Integration testing: The units of code (explained in point 1) are integrated with each other to complete the project. These units of codes may be written in different coding technology or may these are of different version so this testing is done by developers to ensure that all units of the code are compatible with other and there is no any issue of integration.

The HTML Tidy library is able to fix some malformed XML files. Running your feeds through that before passing them on to the parser may help.

Before using foreach for iteration, reverse the list by the reverse method:

    myList.Reverse();
    foreach( List listItem in myList)
    {
       Console.WriteLine(listItem);
    }

The basic questions that differentiate implementations of "CopyStream" are:

• size of the reading buffer
• size of the writes
• Can we use more than one thread (writing while we are reading).

The answers to these questions result in vastly different implementations of CopyStream and are dependent on what kind of streams you have and what you are trying to optimize. The "best" implementation would even need to know what specific hardware the streams were reading and writing to.

"but does that mean it should just be an example of the sort of expression you could use, or should it be an actual expression, that can be executed (eval etc..) to recreate the object? Or... should it be just a rehasing of the actual expression which was used, for pure information purposes?"

Wow, that's a lot of hand-wringing.

1. An "an example of the sort of expression you could use" would not be a representation of a specific object. That can't be useful or meaningful.

2. What is the difference between "an actual expression, that can ... recreate the object" and "a rehasing of the actual expression which was used [to create the object]"? Both are an expression that creates the object. There's no practical distinction between these. A repr call could produce either a new expression or the original expression. In many cases, they're the same.

Note that this isn't always possible, practical or desirable.

In some cases, you'll notice that repr() presents a string which is clearly not an expression of any kind. The default repr() for any class you define isn't useful as an expression.

In some cases, you might have mutual (or circular) references between objects. The repr() of that tangled hierarchy can't make sense.

In many cases, an object is built incrementally via a parser. For example, from XML or JSON or something. What would the repr be? The original XML or JSON? Clearly not, since they're not Python. It could be some Python expression that generated the XML. However, for a gigantic XML document, it might not be possible to write a single Python expression that was the functional equivalent of parsing XML.

The solution:
just change localhost for the IP of your PC
if you want to know this: Windows+r > cmd > ipconfig
example: http://192.168.0.107/directory/service/program.php?action=sendSomething
just replace 192.168.0.107 for your own IP (don't try 127.0.0.1 because it's same as localhost)

Check if the Node is a Dom Element, cast, and call getElementsByTagName()

Node doc = docs.item(i);
if(doc instanceof Element) {
    Element docElement = (Element)doc;
    ...
    cell = doc.getElementsByTagName("aoo").item(0);
}

On my system (Windows 8.1), the problem was with the server configuration. The server worked for the first time when I installed it. However, I forgot to check the "run as a service" option and this caused all the problem. I tried all possible solutions available on SO but nothing worked. So, I decided to reinstall MySQL Workbench. On executing the same msi file that I earlier used to install MySQL workbench, I reconfigured the server and allowed to run the server as a service.

Remember call requestFocus() before setSelection for edittext.

Being au fait with patterns as defined by (say) the GOF book, and naming objects after these gets me a long way in naming classes, organising them and communicating intent. Most people will understand this nomenclature (or at least a major part of it).

This version displays the schema, the table name and an ordered, comma separated list of primary keys. Object_Id() does not work for link servers so we filter by the table name.

Without the REPLACE(Si1.Column_Name, '', '') it would show the xml opening and closing tags for Column_Name on the database I was testing on. I am not sure why the database required a replace for 'Column_Name' so if someone knows then please comment.

From what I understand, removing a node directly does not work in Firefox, only Internet Explorer. So, to support Firefox, you have to go up to the parent to remove it's child.

We use the Assergs Application Framework themes:

They have a nice office look and feel to it :)

Try something like this:

foreach (ListItem listItem in YrChkBox.Items)
{
    if (listItem.Selected)
    { 
       //do some work 
    }
    else 
    {

    }
}

Yes, i also I fixed it changing in the js libraries to the unminified.

For example, in the tag, change:

<script type="text/javascript" src="js/jquery.ui.core.min.js"></script>
<script type="text/javascript" src="js/jquery.ui.widget.min.js"></script>
<script type="text/javascript" src="js/jquery.ui.rcarousel.min.js"></script>

For:

<script type="text/javascript" src="js/jquery.ui.core.js"></script>
<script type="text/javascript" src="js/jquery.ui.widget.js"></script>
<script type="text/javascript" src="js/jquery.ui.rcarousel.js"></script>

Quiting the 'min' as unminified.

Thanks for the idea.

Newer versions of svn support the --show-item argument:

svn info --show-item revision

For the revision number of your local working copy, use:

svn info --show-item last-changed-revision

You can use os.system() to execute a command line like this:

svn info | grep "Revision" | awk '{print $2}'

I do that in my nightly build scripts.

Also on some platforms there is a svnversion command, but I think I had a reason not to use it. Ahh, right. You can't get the revision number from a remote repository to compare it to the local one using svnversion.

I know this question was asked awhile ago, but I have done this before and it allows for more control when aligning items.If you look at it like web programming, it helps. You just nest another LinearLayout that will contain your button inside of it. You can then change the gravity of the button's layout and make it go to the right while the TextView is still on the left.

Try this code:

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"             
android:orientation="horizontal" 
android:layout_marginTop="35dp">

<TextView
    android:id="@+id/lblExpenseCancel"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/cancel" 
    android:textColor="#404040"         
    android:layout_marginLeft="10dp" 
    android:textSize="20sp" 
    android:layout_marginTop="9dp"/>

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="right"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/btnAddExpense"
        android:layout_width="wrap_content"
        android:layout_height="45dp"
        android:background="@drawable/stitch_button"
        android:layout_marginLeft="10dp"                    
        android:text="@string/add" 
        android:layout_gravity="right" 
        android:layout_marginRight="15dp"/>

</LinearLayout>

You may have to play with the padding on the nested layout so that it acts how you want it.

You can use a loop to do it. Here's an example using a with_items loop:

- name: Set some kernel parameters
  lineinfile:
    dest: /etc/sysctl.conf
    regexp: "{{ item.regexp }}"
    line: "{{ item.line }}"
  with_items:
    - { regexp: '^kernel.shmall', line: 'kernel.shmall = 2097152' }
    - { regexp: '^kernel.shmmax', line: 'kernel.shmmax = 134217728' }
    - { regexp: '^fs.file-max', line: 'fs.file-max = 65536' }

If you are in event context, in jQuery, you can retrieve the selected option element using :
$(this).find('option:selected') like this :

$('dropdown_selector').change(function() {
    //Use $option (with the "$") to see that the variable is a jQuery object
    var $option = $(this).find('option:selected');
    //Added with the EDIT
    var value = $option.val();//to get content of "value" attrib
    var text = $option.text();//to get <option>Text</option> content
});

Edit

As mentioned by PossessWithin, My answer just answer to the question : How to select selected "Option".

Next, to get the option value, use option.val().

For some databases, you can just explicitly insert a NULL into the auto_increment column:

INSERT INTO table_name VALUES (NULL, 'my name', 'my group')

This will draw a line that passes through the points (-1, 1) and (12, 4), and another one that passes through the points (1, 3) et (10, 2)

x1 are the x coordinates of the points for the first line, y1 are the y coordinates for the same -- the elements in x1 and y1 must be in sequence.

x2 and y2 are the same for the other line.

import matplotlib.pyplot as plt
x1, y1 = [-1, 12], [1, 4]
x2, y2 = [1, 10], [3, 2]
plt.plot(x1, y1, x2, y2, marker = 'o')
plt.show()

I suggest you spend some time reading / studying the basic tutorials found on the very rich matplotlib website to familiarize yourself with the library.

What if I don't want line segments?

There are no direct ways to have lines extend to infinity... matplotlib will either resize/rescale the plot so that the furthest point will be on the boundary and the other inside, drawing line segments in effect; or you must choose points outside of the boundary of the surface you want to set visible, and set limits for the x and y axis.

As follows:

import matplotlib.pyplot as plt
x1, y1 = [-1, 12], [1, 10]
x2, y2 = [-1, 10], [3, -1]
plt.xlim(0, 8), plt.ylim(-2, 8)
plt.plot(x1, y1, x2, y2, marker = 'o')
plt.show()

I found a much cleaner solution for this:

ORDER BY array_position(ARRAY['f', 'p', 'i', 'a']::varchar[], x_field)

Note: array_position needs Postgres v9.5 or higher.

something like import sys; sys.exit(0) ?

My not very revealing answer:

private String md5(String s) {
    try {
        MessageDigest m = MessageDigest.getInstance("MD5");
        m.update(s.getBytes(), 0, s.length());
        BigInteger i = new BigInteger(1,m.digest());
        return String.format("%1$032x", i);         
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    return null;
}

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

There is an 'exceptions' window in VS2005 ... try Ctrl+Alt+E when debugging and click on the 'Thrown' checkbox for the exception you want to stop on.

Spending some time coming up with an SKU naming strategy can help you. You’ll be able to make it easy for team members to read and understand what each SKU represents. Use a value that is meaningful to your organization.

Ultimately, your SKU is a way to record important product information, so the more straightforward it is, the better for everyone.

Sticking to alphanumeric SKUs and substituting “-” or “_” for space is always the safest and best bet.

E.g. Your app name: Social Point, Submit year: 2020 = Your SKU is: Social_Point_2020

You can use JTextArea and remove editing capabilities to get normal read-only multiline text.

JTextArea textArea = new JTextArea("line\nline\nline");
textArea.setEditable(false);

JTextArea

setEditable

On my device TimeZone.getDefault() is always returning UTC time zone.

I need to do this to get user configured time zone :

TimeZone.setDefault(null)
val tz = TimeZone.getDefault()

It will return user selected timezone.

If you're using SQL Server, look into DATEPART.

http://msdn.microsoft.com/en-us/library/ms174420(SQL.90).aspx

DATEPART(mm, [THE DATE YOU'RE LOOKING AT])

You can then use normal integer logic with it. Same for year, just use yy instead of mm.

>>> A = np.random.randint(5, size=(10,3))
>>> A
array([[1, 3, 0],
       [3, 2, 0],
       [0, 2, 1],
       [1, 1, 4],
       [3, 2, 2],
       [0, 1, 0],
       [1, 3, 1],
       [0, 4, 1],
       [2, 4, 2],
       [3, 3, 1]])
>>> idx = np.random.randint(10, size=2)
>>> idx
array([7, 6])
>>> A[idx,:]
array([[0, 4, 1],
       [1, 3, 1]])

Putting it together for a general case:

A[np.random.randint(A.shape[0], size=2), :]

For non replacement (numpy 1.7.0+):

A[np.random.choice(A.shape[0], 2, replace=False), :]

I do not believe there is a good way to generate random list without replacement before 1.7. Perhaps you can setup a small definition that ensures the two values are not the same.

You need to tell scp where to send the file. In your command that is not working:

scp C:\Users\Admin\Desktop\WMU\5260\A2.c ~

You have not mentioned a remote server. scp uses : to delimit the host and path, so it thinks you have asked it to download a file at the path \Users\Admin\Desktop\WMU\5260\A2.c from the host C to your local home directory.

The correct upload command, based on your comments, should be something like:

C:\> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:

If you are running the command from your home directory, you can use a relative path:

C:\Users\Admin> pscp Desktop\WMU\5260\A2.c [email protected]:

You can also mention the directory where you want to this folder to be downloaded to at the remote server. i.e by just adding a path to the folder as below:

C:/> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:/home/path_to_the_folder/

I wrote a personal Bash library and scripting framework that uses GNU shtool to do a rather accurate platform detection.

GNU shtool is a very portable set of scripts that contains, among other useful things, the 'shtool platform' command. Here is the output of:

shtool platform -v -F "%sc (%ac) %st (%at) %sp (%ap)"

on a few different machines:

Mac OS X Leopard: 
    4.4BSD/Mach3.0 (iX86) Apple Darwin 9.6.0 (i386) Apple Mac OS X 10.5.6 (iX86)

Ubuntu Jaunty server:
    LSB (iX86) GNU/Linux 2.9/2.6 (i686) Ubuntu 9.04 (iX86)

Debian Lenny:
    LSB (iX86) GNU/Linux 2.7/2.6 (i686) Debian GNU/Linux 5.0 (iX86)

This produces pretty satisfactory results, as you can see. GNU shtool is a little slow, so I actually store and update the platform identification in a file on the system that my scripts call. It's my framework, so that works for me, but your mileage may vary.

Now, you'll have to find a way to package shtool with your scripts, but it's not a hard exercise. You can always fall back on uname output, also.

EDIT:

I missed the post by Teddy about config.guess (somehow). These are very similar scripts, but not the same. I personally use shtool for other uses as well, and it has been working quite well for me.

You wouldn’t: it’s messy and hard to read.

You’re looking for the switch statement in the first case. The second is fine as it is but still could be converted for consistency

Ternary statements are much more suited to boolean values and alternating logic.

due to Same Origin Policy, only work under same origin

! [rejected] master -> master (fetch first) error: failed to push some refs to '[email protected]:'

Successfully solved the problem using --force command. so, you must used
git push origin master --force

If you got the following error

ufgtoolspg=> COPY (SELECT foo, bar FROM baz) TO '/tmp/query.csv' (format csv, delimiter ';');
ERROR:  must be superuser to COPY to or from a file
HINT:  Anyone can COPY to stdout or from stdin. psql's \copy command also works for anyone.

you can run it in this way:

psql somepsqllink_or_credentials -c "COPY (SELECT foo, bar FROM baz) TO STDOUT (format csv, delimiter ';')"  > baz.csv

To expand on @cybersnoopy 's suggestion here

if you had a .proto file with a message like so:

message Request {
    oneof option {
        int64 option_value = 1;
    }
}

You can make use of the case options provided (java generated code):

So we can now write some code as follows:

Request.OptionCase optionCase = request.getOptionCase();
OptionCase optionNotSet = OPTION_NOT_SET;

if (optionNotSet.equals(optionCase)){
    // value not set
} else {
    // value set
}

You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

I found a tool in Github that could possibly be a solution to this question. https://incarnate.github.io/curl-to-php/ I hope that will be useful

Just adding another possibility as it might help someone that's trying to both iterate over an array AND maintain a count. For example, the code below goes through an array named items and only displays the first 3 items. Notice that the each and the if are native jade and don't need a hyphen.

ul
  - var count = 0;
  each item in items
    if count < 3
      li= item.name

First of all, you have to define an index on the foreign key column in the referring table (so foo_bar.foo_id, in your case). Then, go to relation view (in the referring table) and select the referred column (so in your case foo.id) and the on update and on delete actions.

I think foreign keys are useful if you have multiple tables linked to one another, in particular, your delete scripts will become very short if you set the referencing options correctly.

EDIT: Make sure both of the tables have the InnoDB engine selected.

I agree that in most cases the if (!(x instanceof Y)) {...} is the best approach, but in some cases creating an isY(x) function so you can if (!isY(x)) {...} is worthwhile.

I'm a typescript novice, and I've bumped into this S/O question a bunch of times over the last few weeks, so for the googlers the typescript way to do this is to create a typeguard like this:

typeGuards.ts

export function isHTMLInputElement (value: any): value is HTMLInputElement {
  return value instanceof HTMLInputElement
}

usage

if (!isHTMLInputElement(x)) throw new RangeError()
// do something with an HTMLInputElement

I guess the only reason why this might be appropriate in typescript and not regular js is that typeguards are a common convention, so if you're writing them for other interfaces, it's reasonable / understandable / natural to write them for classes too.

There's more detail about user defined type guards like this in the docs

Gradle looks for gradle.properties files in these places:

• in project build dir (that is where your build script is)
• in sub-project dir
• in gradle user home (defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle)

Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Reference: https://gradle.org/docs/current/userguide/build_environment.html

I found solution. It works fine when I throw away next line from form:

enctype="multipart/form-data"

And now it pass all parameters at request ok:

 <form action="/registration" method="post">
   <%-- error messages --%>
   <div class="form-group">
    <c:forEach items="${registrationErrors}" var="error">
    <p class="error">${error}</p>
     </c:forEach>
   </div>

For everyone who clicked on this to find out what the content of your HashMap is, the toString method (docs) actually works with most objects. (note: a java array is not an object!)

So this woks perfectly fine for debugging purposes:

System.out.println(myMap.toString());

>>> {key1=value1, key2=value2}

Go to control panel ? services, look for MySQL and right click choose properties. If there, in “path to EXE file”, there is a parameter like

--defaults-file="X:\path\to\my.ini"

this is the file the server actually uses (independent of what mysql --help prints).

Would that work for you?

public class Main {

public static void main(String[] args) {
    Random r = new Random(System.currentTimeMillis());
    System.out.println(r.nextInt(100000) * 0.000001);
}

}

result e.g. 0.019007

Remove obj and just do this inside your for loop:

arr.push(i);

Also, the i < yearEnd condition will not include the final year, so change it to i <= yearEnd.

if it is a link then $(this).unbind("click"); would re-enable the link clicking and the default behavior would be restored.

I have created a demo JS fiddle to demonstrate how this works:

Here is the code of the JS fiddle:

HTML:

<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<a href="http://jquery.com">Default click action is prevented, only on the third click it would be enabled</a>
<div id="log"></div>

Javascript:

<script>
var counter = 1;
$(document).ready(function(){
$( "a" ).click(function( event ) {
  event.preventDefault();

  $( "<div>" )
    .append( "default " + event.type + " prevented "+counter )
    .appendTo( "#log" );

    if(counter == 2)
    {
        $( "<div>" )
    .append( "now enable click" )
    .appendTo( "#log" );

    $(this).unbind("click");//-----this code unbinds the e.preventDefault() and restores the link clicking behavior
    }
    else
    {
        $( "<div>" )
    .append( "still disabled" )
    .appendTo( "#log" );
    }
    counter++;
});
});
</script>

You will want to set the MdiParent property of your new form to the name of the MDI parent form, as follows:

dim form as new yourform
form.show()
form.MdiParent = nameParent
