The method, as indicated by their technical considerations page, is correct - so you're definitely not doing anything wrong. However, this bug report on Google Code indicate that there is a problem with the fonts Google produced for this, specifically the IE version. This only seems to affect only some fonts, but it's a real bummmer.

The answers on the thread indicate that the problem lies with the files Google's serving up, so there's nothing you can do about it. The author suggest getting the fonts from alternative locations, like FontSquirrel, and serving it locally instead, in which case you might also be interested in sites like the League of Movable Type.

N.B. As of Oct 2010 the issue is reported as fixed and closed on the Google Code bug report.

Status of the issue, June 2014: Fixed with Chrome 37

Finally, the Chrome team will release a fix for this issue with Chrome 37 which will be released to public in July 2014. See example comparison of current stable Chrome 35 and latest Chrome 37 (early development preview) here:

Status of the issue, December 2013

1.) There is NO proper solution when loading fonts via @import, <link href= or Google's webfont.js. The problem is that Chrome simply requests .woff files from Google's API which render horribly. Surprisingly all other font file types render beautifully. However, there are some CSS tricks that will "smoothen" the rendered font a little bit, you'll find the workaround(s) deeper in this answer.

2.) There IS a real solution for this when self-hosting the fonts, first posted by Jaime Fernandez in another answer on this Stackoverflow page, which fixes this issue by loading web fonts in a special order. I would feel bad to simply copy his excellent answer, so please have a look there. There is also an (unproven) solution that recommends using only TTF/OTF fonts as they are now supported by nearly all browsers.

3.) The Google Chrome developer team works on that issue. As there have been several huge changes in the rendering engine there's obviously something in progress.

I've written a large blog post on that issue, feel free to have a look: How to fix the ugly font rendering in Google Chrome

Reproduceable examples

See how the example from the initial question look today, in Chrome 29:

POSITIVE EXAMPLE:

Solution

Fixing the above screenshot with -webkit-text-stroke:

First row is default, second has:

-webkit-text-stroke: 0.3px;

Third row has:

-webkit-text-stroke: 0.6px;

So, the way to fix those fonts is simply giving them

-webkit-text-stroke: 0.Xpx;

or the RGBa syntax (by nezroy, found in the comments! Thanks!)

-webkit-text-stroke: 1px rgba(0,0,0,0.1)

There's also an outdated possibility: Give the text a simple (fake) shadow:

text-shadow: #fff 0px 1px 1px;

RGBa solution (found in Jasper Espejo's blog):

text-shadow: 0 0 1px rgba(51,51,51,0.2);

I made a blog post on this:

If you want to be updated on this issue, have a look on the according blog post: How to fix the ugly font rendering in Google Chrome. I'll post news if there're news on this.

My original answer:

This is a big bug in Google Chrome and the Google Chrome Team does know about this, see the official bug report here. Currently, in May 2013, even 11 months after the bug was reported, it's not solved. It's a strange thing that the only browser that messes up Google Webfonts is Google's own browser Chrome (!). But there's a simple workaround that will fix the problem, please see below for the solution.

STATEMENT FROM GOOGLE CHROME DEVELOPMENT TEAM, MAY 2013

Official statement in the bug report comments:

Our Windows font rendering is actively being worked on. ... We hope to have something within a milestone or two that developers can start playing with. How fast it goes to stable is, as always, all about how fast we can root out and burn down any regressions.

Use the @import method:

@import url('https://fonts.googleapis.com/css?family=Open+Sans&display=swap');

Obviously, "Open Sans" (Open+Sans) is the font that is imported. So replace it with yours. If the font's name has multiple words, URL-encode it by adding a + sign between each word, as I did.

Make sure to place the @import at the very top of your CSS, before any rules.

Google Fonts can automatically generate the @import directive for you. Once you have chosen a font, click the (+) icon next to it. In bottom-left corner, a container titled "1 Family Selected" will appear. Click it, and it will expand. Use the "Customize" tab to select options, and then switch back to "Embed" and click "@import" under "Embed Font". Copy the CSS between the <style> tags into your stylesheet.

The other answers are helpful, but the JSON in your question isn't valid. I have formatted it to make it clearer below, note the missing single quote on line 24.

There are a lot of great articles on how to manipulate objects in Javascript (whether using Node JS or a browser). I suggest here is a good place to start: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects

Instead of dropping the milliseconds then comparing, why not compare the difference?

DateTime x; DateTime y;
bool areEqual = (x-y).TotalSeconds == 0;

or

TimeSpan precision = TimeSpan.FromSeconds(1);
bool areEqual = (x-y).Duration() < precision;

There's a simple solution, that at least for me, is the only feasible solution.

The problem is that all the answers I see being tossed around - using Joda, or Calendar, or Date, or whatever - only take the amount of milliseconds into consideration. They end up counting the number of 24-hour cycles between two dates, rather than the actual number of days. So something from Jan 1st 11pm to Jan 2nd 1am will return 0 days.

To count the actual number of days between startDate and endDate, simply do:

// Find the sequential day from a date, essentially resetting time to start of the day
long startDay = startDate.getTime() / 1000 / 60 / 60 / 24;
long endDay = endDate.getTime() / 1000 / 60 / 60 / 24;

// Find the difference, duh
long daysBetween = endDay - startDay;

This will return "1" between Jan 2nd and Jan 1st. If you need to count the end day, just add 1 to daysBetween (I needed to do that in my code since I wanted to count the total number of days in the range).

This is somewhat similar to what Daniel has suggested but smaller code I suppose.

Check that ORACLE_HOME environment variable is pointing to the correct oracle home. In my case it was changed by another software installation.

One reason POST is worse for security is that GET is logged by default, parameters and all data is almost universally logged by your webserver.

POST is the opposite, it's almost universally not logged, leading to very difficult to spot attacker activity.

I don't buy the argument "it's too big", that's no reason to not log anything, at least 1KB, would go a long way for people to identify attackers working away at a weak entry-point until it pop's, then POST does a double dis-service, by enabling any HTTP based back-door to silently pass unlimited amounts of data.

There are several other ways, besides using the in operator (easiest):

index()

>>> try:
...   "xxxxABCDyyyy".index("test")
... except ValueError:
...   print "not found"
... else:
...   print "found"
...
not found

find()

>>> if "xxxxABCDyyyy".find("ABCD") != -1:
...   print "found"
...
found

re

>>> import re
>>> if re.search("ABCD" , "xxxxABCDyyyy"):
...  print "found"
...
found

You can create a list of objects in one line using a list comprehension.

class MyClass(object): pass

objs = [MyClass() for i in range(10)]

print(objs)

I like the simple one-liner answer above:

for user in $(cut -f1 -d: /etc/passwd); do crontab -u $user -l; done

But Solaris which does not have the -u flag and does not print the user it's checking, you can modify it like so:

for user in $(cut -f1 -d: /etc/passwd); do echo User:$user; crontab -l $user 2>&1 | grep -v crontab; done

You will get a list of users without the errors thrown by crontab when an account is not allowed to use cron etc. Be aware that in Solaris, roles can be in /etc/passwd too (see /etc/user_attr).

Here's another way that I didn't see here:

>>> foo = dict(a=1,b=2)
>>> foo
{'a': 1, 'b': 2}
>>> goo = dict(c=3,**foo)
>>> goo
{'c': 3, 'a': 1, 'b': 2}

You can use the dictionary constructor and implicit expansion to reconstruct a dictionary. Moreover, interestingly, this method can be used to control the positional order during dictionary construction (post Python 3.6). In fact, insertion order is guaranteed for Python 3.7 and above!

>>> foo = dict(a=1,b=2,c=3,d=4)
>>> new_dict = {k: v for k, v in list(foo.items())[:2]}
>>> new_dict
{'a': 1, 'b': 2}
>>> new_dict.update(newvalue=99)
>>> new_dict
{'a': 1, 'b': 2, 'newvalue': 99}
>>> new_dict.update({k: v for k, v in list(foo.items())[2:]})
>>> new_dict
{'a': 1, 'b': 2, 'newvalue': 99, 'c': 3, 'd': 4}
>>> 

The above is using dictionary comprehension.

LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP.

This does not print to the Console, but will open you an alert Popup with your message which might be useful for some debugging:

just do:

alert("message");

The easiest (as in least amount of new code required) way to do this is to run the test as a parametrized test (annotate with an @RunWith(Parameterized.class) and add a method to provide 10 empty parameters). That way the framework will run the test 10 times.

This test would need to be the only test in the class, or better put all test methods should need to be run 10 times in the class.

Here is an example:

@RunWith(Parameterized.class)
public class RunTenTimes {

    @Parameterized.Parameters
    public static Object[][] data() {
        return new Object[10][0];
    }

    public RunTenTimes() {
    }

    @Test
    public void runsTenTimes() {
        System.out.println("run");
    }
}

With the above, it is possible to even do it with a parameter-less constructor, but I'm not sure if the framework authors intended that, or if that will break in the future.

If you are implementing your own runner, then you could have the runner run the test 10 times. If you are using a third party runner, then with 4.7, you can use the new @Rule annotation and implement the MethodRule interface so that it takes the statement and executes it 10 times in a for loop. The current disadvantage of this approach is that @Before and @After get run only once. This will likely change in the next version of JUnit (the @Before will run after the @Rule), but regardless you will be acting on the same instance of the object (something that isn't true of the Parameterized runner). This assumes that whatever runner you are running the class with correctly recognizes the @Rule annotations. That is only the case if it is delegating to the JUnit runners.

If you are running with a custom runner that does not recognize the @Rule annotation, then you are really stuck with having to write your own runner that delegates appropriately to that Runner and runs it 10 times.

Note that there are other ways to potentially solve this (such as the Theories runner) but they all require a runner. Unfortunately JUnit does not currently support layers of runners. That is a runner that chains other runners.

One method to do this is to add:

pointer-events: none;

to the element, you want to disable hover on.

(Note: this also disables javascript events on that element too, click events will actually fall through to the element behind ).

Browser Support ( 98.12% as of Jan 1, 2021 )

This seems to be much cleaner

/**
 * This allows you to disable hover events for any elements
*/
.disabled {
  pointer-events: none;  /* <----------- */
  opacity: 0.2;
}

.button {
  border-radius: 30px;
  padding: 10px 15px;
  border: 2px solid #000;
  color: #FFF;
  background: #2D2D2D;
  text-shadow: 1px 1px 0px #000;
  cursor: pointer;
  display: inline-block;
  margin: 10px;
}

.button-red:hover {
  background: red;
}

.button-green:hover {
  background:green;  
}

<div class="button button-red">I'm a red button hover over me</div>

<br />

<div class="button button-green">I'm a green button hover over me</div>

<br />

<div class="button button-red disabled">I'm a disabled red button</div>

<br />

<div class="button button-green disabled">I'm a disabled green button</div>

I use following line of code to fix this problem. Write the following code in web.config file

<configuration>
    <system.web.extensions>
       <scripting>
       <webServices>
       <jsonSerialization maxJsonLength="50000000"/>
      </webServices>
     </scripting>
   </system.web.extensions>
</configuration>

REGEX should be a last resort. PHP has a few functions that will validate for you. In your case, checkdate is the best option. http://php.net/manual/en/function.checkdate.php

import { AfterViewInit, Component, ElementRef} from '@angular/core';

constructor(private elementRef:ElementRef) {}

ngAfterViewInit() {
  this.elementRef.nativeElement.querySelector('my-element')
                                .addEventListener('click', this.onClick.bind(this));
}

onClick(event) {
  console.log(event);
}

For python 3,

    for d in list:
        d.update((k, float(v)) for k, v in d.items())

Well I know this might be a big change or even not suitable for your project, but did you consider not performing the push until you already have the data? That way you only need to draw the view once and the user experience will also be better - the push will move in already loaded.

The way you do this is in the UITableView didSelectRowAtIndexPath you asynchronously ask for the data. Once you receive the response, you manually perform the segue and pass the data to your viewController in prepareForSegue. Meanwhile you may want to show some activity indicator, for simple loading indicator check https://github.com/jdg/MBProgressHUD

You can use lodash sortBy (https://lodash.com/docs/4.17.4#sortBy).

Your code could be like:

const myArray = [  
   {  
      "id":25,
      "name":"Anakin Skywalker",
      "createdAt":"2017-04-12T12:48:55.000Z",
      "updatedAt":"2017-04-12T12:48:55.000Z"
   },
   {  
      "id":1,
      "name":"Luke Skywalker",
      "createdAt":"2017-04-12T11:25:03.000Z",
      "updatedAt":"2017-04-12T11:25:03.000Z"
   }
]

const myOrderedArray = _.sortBy(myArray, o => o.name)

I had PHP7.2 on a Ubuntu 16.04 server and it solved my problem:

sudo apt-get install zip unzip php-zip

Update

Tried this for Ubuntu 18.04 and worked as well.

For rerender you can use in parent component

<template>
  <div v-if="renderComponent">content</div>
</template>
<script>
export default {
   data() {
      return {
        renderComponent: true,
      };
    },
    methods: {
      forceRerender() {
        // Remove my-component from the DOM
        this.renderComponent = false;

        this.$nextTick(() => {
          // Add the component back in
          this.renderComponent = true;
        });
      }
    }
}
</script>

Remove lib from Podfile, then pod install again.

You can do it using write() :

#open file with *.html* extension to write html
file= open("my.html","w")
#write then close file
file.write(html)
file.close()

The method for converting a string to a long is Long.parseLong. Modifying your example:

String s = "1333073704000";
long l = Long.parseLong(s);
// Now l = 1333073704000

It turns out you can also use pow(). For example, you can use the following to express 10 to the 9th.

pow(10, 9)

Along with pow, powf() returns a float instead of a double. I have only tested this on Swift 4 and macOS 10.13.

You could do something like this:

i={'foo':'bar', 'baz':'huh?'}
keys=i.keys()  #in python 3, you'll need `list(i.keys())`
values=i.values()
print keys[values.index("bar")]  #'foo'

However, any time you change your dictionary, you'll need to update your keys,values because dictionaries are not ordered in versions of Python prior to 3.7. In these versions, any time you insert a new key/value pair, the order you thought you had goes away and is replaced by a new (more or less random) order. Therefore, asking for the index in a dictionary doesn't make sense.

As of Python 3.6, for the CPython implementation of Python, dictionaries remember the order of items inserted. As of Python 3.7+ dictionaries are ordered by order of insertion.

Also note that what you're asking is probably not what you actually want. There is no guarantee that the inverse mapping in a dictionary is unique. In other words, you could have the following dictionary:

d={'i':1, 'j':1}

In that case, it is impossible to know whether you want i or j and in fact no answer here will be able to tell you which ('i' or 'j') will be picked (again, because dictionaries are unordered). What do you want to happen in that situation? You could get a list of acceptable keys ... but I'm guessing your fundamental understanding of dictionaries isn't quite right.

For Windows line endings:

(Turn on regex - Alt+R)

Find: \\r\\n

Replace: \r\n

Note: Recent npm versions do this automatically when package-locks are enabled, so this is not necessary except for removing development packages with the --production flag.

Run npm prune to remove modules not listed in package.json.

From npm help prune:

This command removes "extraneous" packages. If a package name is provided, then only packages matching one of the supplied names are removed.

Extraneous packages are packages that are not listed on the parent package's dependencies list.

If the --production flag is specified, this command will remove the packages specified in your devDependencies.

I had the same issue too, to solve this, check in References of your project if the version of Newtonsoft.Json was updated (probablly don´t), then remove it and check in your either Web.config or App.config wheter the element dependentAssembly was updated as follows:

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
</dependentAssembly>

After that, rebuild the project again (the dll will be replaced with the correct version)

Simply write to file string.Empty, when append is set to false in StreamWriter. I think this one is easiest to understand for beginner.

private void ClearFile()
{
    if (!File.Exists("TextFile.txt"))
        File.Create("TextFile.txt");

    TextWriter tw = new StreamWriter("TextFile.txt", false);
    tw.Write(string.Empty);
    tw.Close();
}

I think this should work .. :)

<input type="checkbox" name="Days[]" value="Daily">Daily<br>
<input type="checkbox" name="Days[]" value="Sunday">Sunday<br>

This solved it for me:
https://gist.github.com/beccasaurus/929007/a8f820b153a1cfdee3d06a9c0a1d7ebfced8bb77

TL;DR:
Problem:
localhost returns expected content, remote IP alters 400 content to "Bad Request"
Solution:
Adding <httpErrors existingResponse="PassThrough"></httpErrors> to web.config/configuration/system.webServer solved this for me; now all servers (local & remote) return the exact same content (generated by me) regardless of the IP address and/or HTTP code I return.

This version should work:

DELETE WorkRecord2
FROM WorkRecord2 
INNER JOIN Employee ON EmployeeRun=EmployeeNo
Where Company = '1' AND Date = '2013-05-06'

I have found a solution how to style just the component element. I have not found any documentation how it works, but you can put attributes values into the component directive, under the 'host' property like this:

@Component({
    ...
    styles: [`
      :host {
        'style': 'display: table; height: 100%',
        'class': 'myClass'
      }`
})
export class MyComponent
{
    constructor() {}

    // Also you can use @HostBinding decorator
    @HostBinding('style.background-color') public color: string = 'lime';
    @HostBinding('class.highlighted') public highlighted: boolean = true;
}

UPDATE: As Günter Zöchbauer mentioned, there was a bug, and now you can style the host element even in css file, like this:

:host{ ... }

If you declare your callback as mentioned by @lex82 like

callback = "callback(item.id, arg2)"

You can call the callback method in the directive scope with object map and it would do the binding correctly. Like

scope.callback({arg2:"some value"});

without requiring for $parse. See my fiddle(console log) http://jsfiddle.net/k7czc/2/

Update: There is a small example of this in the documentation:

& or &attr - provides a way to execute an expression in the context of the parent scope. If no attr name is specified then the attribute name is assumed to be the same as the local name. Given and widget definition of scope: { localFn:'&myAttr' }, then isolate scope property localFn will point to a function wrapper for the count = count + value expression. Often it's desirable to pass data from the isolated scope via an expression and to the parent scope, this can be done by passing a map of local variable names and values into the expression wrapper fn. For example, if the expression is increment(amount) then we can specify the amount value by calling the localFn as localFn({amount: 22}).

SHORT ANSWER

How to do in your case:

int argument = 5; // example with int but could be another type
Mockito.when(mockMyAgent.otherMethod(Mockito.anyInt()).thenReturn(requiredReturnArg(argument));

LONG ANSWER

Actually what you want to do is possible, at least in Java 8. Maybe you didn't get this answer by other people because I am using Java 8 that allows that and this question is before release of Java 8 (that allows to pass functions, not only values to other functions).

Let's simulate a call to a DataBase query. This query returns all the rows of HotelTable that have FreeRoms = X and StarNumber = Y. What I expect during testing, is that this query will give back a List of different hotel: every returned hotel has the same value X and Y, while the other values and I will decide them according to my needs. The following example is simple but of course you can make it more complex.

So I create a function that will give back different results but all of them have FreeRoms = X and StarNumber = Y.

static List<Hotel> simulateQueryOnHotels(int availableRoomNumber, int starNumber) {
    ArrayList<Hotel> HotelArrayList = new ArrayList<>();
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Rome, 1, 1));
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Krakow, 7, 15));
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Madrid, 1, 1));
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Athens, 4, 1));

    return HotelArrayList;
}

Maybe Spy is better (please try), but I did this on a mocked class. Here how I do (notice the anyInt() values):

//somewhere at the beginning of your file with tests...
@Mock
private DatabaseManager mockedDatabaseManager;

//in the same file, somewhere in a test...
int availableRoomNumber = 3;
int starNumber = 4;
// in this way, the mocked queryOnHotels will return a different result according to the passed parameters
when(mockedDatabaseManager.queryOnHotels(anyInt(), anyInt())).thenReturn(simulateQueryOnHotels(availableRoomNumber, starNumber));

Here is the JSfiddle Demo

I changed your HTML and give your input textfield an id of value. I removed the passed param for your verifyorder function, and instead grab the content of your textfield by using document.getElementById(); then i convert the str into value with +order so you can check if it's greater than zero:

<input type="text" maxlength="3" name="value" id='value' />
<input type="button" value="submit" onclick="verifyorder()" />
</p>
<p id="error"></p>
<p id="detspace"></p> 

function verifyorder() {
        var order = document.getElementById('value').value;
        if (+order > 0) {
            alert(+order);
            return true;
        }
        else {
            alert("Sorry, you need to enter a positive integer value, try again");
            document.getElementById('error').innerHTML = "Sorry, you need to enter a positive integer value, try again";
        }
    }

You can set the System.out print stream via setOut() (and for in and err). Can you redirect this to a print stream that records to a string, and then inspect that ? That would appear to be the simplest mechanism.

(I would advocate, at some stage, convert the app to some logging framework - but I suspect you already are aware of this!)

You need the ip of the other pc and do:

This is an old question with valuable answers, but I was still a bit confused until I found a real life example that shows the issue with 3NF. Maybe not suitable for an 8-year old child but hope it helps.

Tomorrow I'll meet the teachers of my eldest daughter in one of those quarterly parent/teachers meetings. Here's what my diary looks like (names and rooms have been changed):

Teacher   | Date             | Room
----------|------------------|-----
Mr Smith  | 2018-12-18 18:15 | A12 
Mr Jones  | 2018-12-18 18:30 | B10 
Ms Doe    | 2018-12-18 18:45 | C21 
Ms Rogers | 2018-12-18 19:00 | A08 

There's only one teacher per room and they never move. If you have a look, you'll see that: (1) for every attribute Teacher, Date, Room, we have only one value per row. (2) super-keys are: (Teacher, Date, Room), (Teacher, Date) and (Date, Room) and candidate keys are obviously (Teacher, Date) and (Date, Room).

_{(Teacher, Room) is not a superkey because I will complete the table next quarter and I may have a row like this one (Mr Smith did not move!):}

Teacher  | Date             | Room
---------|------------------| ----
Mr Smith | 2019-03-19 18:15 | A12

What can we conclude? (1) is an informal but correct formulation of 1NF. From (2) we see that there is no "non prime attribute": 2NF and 3NF are given for free.

My diary is 3NF. Good! No. Not really because no data modeler would accept this in a DB schema. The Room attribute is dependant on the Teacher attribute (again: teachers do not move!) but the schema does not reflect this fact. What would a sane data modeler do? Split the table in two:

Teacher   | Date
----------|-----------------
Mr Smith  | 2018-12-18 18:15
Mr Jones  | 2018-12-18 18:30
Ms Doe    | 2018-12-18 18:45
Ms Rogers | 2018-12-18 19:00

And

Teacher   | Room
----------|-----
Mr Smith  | A12
Mr Jones  | B10
Ms Doe    | C21
Ms Rogers | A08

But 3NF does not deal with prime attributes dependencies. This is the issue: 3NF compliance is not enough to ensure a sound table schema design under some circumstances.

With BCNF, you don't care if the attribute is a prime attribute or not in 2NF and 3NF rules. For every non trivial dependency (subsets are obviously determined by their supersets), the determinant is a complete super key. In other words, nothing is determined by something else than a complete super key (excluding trivial FDs). (See other answers for formal definition).

As soon as Room depends on Teacher, Room must be a subset of Teacher (that's not the case) or Teacher must be a super key (that's not the case in my diary, but thats the case when you split the table).

To summarize: BNCF is more strict, but in my opinion easier to grasp, than 3NF:

• in most of cases, BCNF is identical to 3NF;
• in other cases, BCNF is what you think/hope 3NF is.

First of all, the code you wrote isn't portable, even if you get it to work. Why use OS-specific functions when there is a perfectly platform-independent way of doing it? Here's a version that uses just a single header file and is portable to any platform that implements the C standard library.

#include <stdio.h>

int main(int argc, char **argv)
{
    FILE* sourceFile;
    FILE* destFile;
    char buf[50];
    int numBytes;

    if(argc!=3)
    {
        printf("Usage: fcopy source destination\n");
        return 1;
    }

    sourceFile = fopen(argv[1], "rb");
    destFile = fopen(argv[2], "wb");

    if(sourceFile==NULL)
    {
        printf("Could not open source file\n");
        return 2;
    }
    if(destFile==NULL)
    {
        printf("Could not open destination file\n");
        return 3;
    }

    while(numBytes=fread(buf, 1, 50, sourceFile))
    {
        fwrite(buf, 1, numBytes, destFile);
    }

    fclose(sourceFile);
    fclose(destFile);

    return 0;
}

EDIT: The glibc reference has this to say:

In general, you should stick with using streams rather than file descriptors, unless there is some specific operation you want to do that can only be done on a file descriptor. If you are a beginning programmer and aren't sure what functions to use, we suggest that you concentrate on the formatted input functions (see Formatted Input) and formatted output functions (see Formatted Output).

If you are concerned about portability of your programs to systems other than GNU, you should also be aware that file descriptors are not as portable as streams. You can expect any system running ISO C to support streams, but non-GNU systems may not support file descriptors at all, or may only implement a subset of the GNU functions that operate on file descriptors. Most of the file descriptor functions in the GNU library are included in the POSIX.1 standard, however.

Had the same issue. Sorted it by defer loading select2

<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.8/js/select2.min.js" defer></script>

I was dealing with this issue after upgrading from Visual Studio 2013 to Visual Studio 2015 After trying most of the advice found in this and other similar SO posts, I finally found the problem. The first part of the fix was to update all of my NuGet stuff to the latest version (you might need to do this in VS13 if you are experiencing the Nuget bug) after, I had to, as you may need to, fix the versions listed in the Views Web.config. This includes:

1. Fix MVC versions and its child libraries to the new version (expand the References then right click onSytem.Web.MVC then Properties to get your version)
2. Fix the Razor version.

Mine looked like this:

For .Net <= 4.0 Use the TimeSpan class.

TimeSpan t = TimeSpan.FromSeconds( secs );

string answer = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", 
                t.Hours, 
                t.Minutes, 
                t.Seconds, 
                t.Milliseconds);

(As noted by Inder Kumar Rathore) For .NET > 4.0 you can use

TimeSpan time = TimeSpan.FromSeconds(seconds);

//here backslash is must to tell that colon is
//not the part of format, it just a character that we want in output
string str = time .ToString(@"hh\:mm\:ss\:fff");

(From Nick Molyneux) Ensure that seconds is less than TimeSpan.MaxValue.TotalSeconds to avoid an exception.

TL;DR

1) When you’re using a Factory you create an object, add properties to it, then return that same object. When you pass this factory into your controller, those properties on the object will now be available in that controller through your factory.

app.controller('myFactoryCtrl', function($scope, myFactory){
  $scope.artist = myFactory.getArtist();
});

app.factory('myFactory', function(){
  var _artist = 'Shakira';
  var service = {};

  service.getArtist = function(){
    return _artist;
  }

  return service;
});

2) When you’re using Service, Angular instantiates it behind the scenes with the ‘new’ keyword. Because of that, you’ll add properties to ‘this’ and the service will return ‘this’. When you pass the service into your controller, those properties on ‘this’ will now be available on that controller through your service.

app.controller('myServiceCtrl', function($scope, myService){
  $scope.artist = myService.getArtist();
});

app.service('myService', function(){
  var _artist = 'Nelly';
  this.getArtist = function(){
    return _artist;
  }
});

Non TL;DR

1) Factory
Factories are the most popular way to create and configure a service. There’s really not much more than what the TL;DR said. You just create an object, add properties to it, then return that same object. Then when you pass the factory into your controller, those properties on the object will now be available in that controller through your factory. A more extensive example is below.

app.factory('myFactory', function(){
  var service = {};
  return service;
});

Now whatever properties we attach to ‘service’ will be available to us when we pass ‘myFactory’ into our controller.

Now let’s add some ‘private’ variables to our callback function. These won’t be directly accessible from the controller, but we will eventually set up some getter/setter methods on ‘service’ to be able to alter these ‘private’ variables when needed.

app.factory('myFactory', function($http, $q){
  var service = {};
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
   _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK';
    return _finalUrl
  }

  return service;
});

Here you’ll notice we’re not attaching those variables/function to ‘service’. We’re simply creating them in order to either use or modify them later.

• baseUrl is the base URL that the iTunes API requires
• _artist is the artist we wish to lookup
• _finalUrl is the final and fully built URL to which we’ll make the call to iTunes makeUrl is a function that will create and return our iTunes friendly URL.

Now that our helper/private variables and function are in place, let’s add some properties to the ‘service’ object. Whatever we put on ‘service’ we’ll be able to directly use in whichever controller we pass ‘myFactory’ into.

We are going to create setArtist and getArtist methods that simply return or set the artist. We are also going to create a method that will call the iTunes API with our created URL. This method is going to return a promise that will fulfill once the data has come back from the iTunes API. If you haven’t had much experience using promises in Angular, I highly recommend doing a deep dive on them.

Below setArtist accepts an artist and allows you to set the artist. getArtist returns the artist callItunes first calls makeUrl() in order to build the URL we’ll use with our $http request. Then it sets up a promise object, makes an $http request with our final url, then because $http returns a promise, we are able to call .success or .error after our request. We then resolve our promise with the iTunes data, or we reject it with a message saying ‘There was an error’.

app.factory('myFactory', function($http, $q){
  var service = {};
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
    _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
    return _finalUrl;
  }

  service.setArtist = function(artist){
    _artist = artist;
  }

  service.getArtist = function(){
    return _artist;
  }

  service.callItunes = function(){
    makeUrl();
    var deferred = $q.defer();
    $http({
      method: 'JSONP',
      url: _finalUrl
    }).success(function(data){
      deferred.resolve(data);
    }).error(function(){
      deferred.reject('There was an error')
    })
    return deferred.promise;
  }

  return service;
});

Now our factory is complete. We are now able to inject ‘myFactory’ into any controller and we’ll then be able to call our methods that we attached to our service object (setArtist, getArtist, and callItunes).

app.controller('myFactoryCtrl', function($scope, myFactory){
  $scope.data = {};
  $scope.updateArtist = function(){
    myFactory.setArtist($scope.data.artist);
  };

  $scope.submitArtist = function(){
    myFactory.callItunes()
      .then(function(data){
        $scope.data.artistData = data;
      }, function(data){
        alert(data);
      })
  }
});

In the controller above we’re injecting in the ‘myFactory’ service. We then set properties on our $scope object that are coming from data from ‘myFactory’. The only tricky code above is if you’ve never dealt with promises before. Because callItunes is returning a promise, we are able to use the .then() method and only set $scope.data.artistData once our promise is fulfilled with the iTunes data. You’ll notice our controller is very ‘thin’. All of our logic and persistent data is located in our service, not in our controller.

2) Service
Perhaps the biggest thing to know when dealing with creating a Service is that that it’s instantiated with the ‘new’ keyword. For you JavaScript gurus this should give you a big hint into the nature of the code. For those of you with a limited background in JavaScript or for those who aren’t too familiar with what the ‘new’ keyword actually does, let’s review some JavaScript fundamentals that will eventually help us in understanding the nature of a Service.

To really see the changes that occur when you invoke a function with the ‘new’ keyword, let’s create a function and invoke it with the ‘new’ keyword, then let’s show what the interpreter does when it sees the ‘new’ keyword. The end results will both be the same.

First let’s create our Constructor.

var Person = function(name, age){
  this.name = name;
  this.age = age;
}

This is a typical JavaScript constructor function. Now whenever we invoke the Person function using the ‘new’ keyword, ‘this’ will be bound to the newly created object.

Now let’s add a method onto our Person’s prototype so it will be available on every instance of our Person ‘class’.

Person.prototype.sayName = function(){
  alert('My name is ' + this.name);
}

Now, because we put the sayName function on the prototype, every instance of Person will be able to call the sayName function in order alert that instance’s name.

Now that we have our Person constructor function and our sayName function on its prototype, let’s actually create an instance of Person then call the sayName function.

var tyler = new Person('Tyler', 23);
tyler.sayName(); //alerts 'My name is Tyler'

So all together the code for creating a Person constructor, adding a function to it’s prototype, creating a Person instance, and then calling the function on its prototype looks like this.

var Person = function(name, age){
  this.name = name;
  this.age = age;
}
Person.prototype.sayName = function(){
  alert('My name is ' + this.name);
}
var tyler = new Person('Tyler', 23);
tyler.sayName(); //alerts 'My name is Tyler'

Now let’s look at what actually is happening when you use the ‘new’ keyword in JavaScript. First thing you should notice is that after using ‘new’ in our example, we’re able to call a method (sayName) on ‘tyler’ just as if it were an object - that’s because it is. So first, we know that our Person constructor is returning an object, whether we can see that in the code or not. Second, we know that because our sayName function is located on the prototype and not directly on the Person instance, the object that the Person function is returning must be delegating to its prototype on failed lookups. In more simple terms, when we call tyler.sayName() the interpreter says “OK, I’m going to look on the ‘tyler’ object we just created, locate the sayName function, then call it. Wait a minute, I don’t see it here - all I see is name and age, let me check the prototype. Yup, looks like it’s on the prototype, let me call it.”.

Below is code for how you can think about what the ‘new’ keyword is actually doing in JavaScript. It’s basically a code example of the above paragraph. I’ve put the ‘interpreter view’ or the way the interpreter sees the code inside of notes.

var Person = function(name, age){
  //The line below this creates an obj object that will delegate to the person's prototype on failed lookups.
  //var obj = Object.create(Person.prototype);

  //The line directly below this sets 'this' to the newly created object
  //this = obj;

  this.name = name;
  this.age = age;

  //return this;
}

Now having this knowledge of what the ‘new’ keyword really does in JavaScript, creating a Service in Angular should be easier to understand.

The biggest thing to understand when creating a Service is knowing that Services are instantiated with the ‘new’ keyword. Combining that knowledge with our examples above, you should now recognize that you’ll be attaching your properties and methods directly to ‘this’ which will then be returned from the Service itself. Let’s take a look at this in action.

Unlike what we originally did with the Factory example, we don’t need to create an object then return that object because, like mentioned many times before, we used the ‘new’ keyword so the interpreter will create that object, have it delegate to it’s prototype, then return it for us without us having to do the work.

First things first, let’s create our ‘private’ and helper function. This should look very familiar since we did the exact same thing with our factory. I won’t explain what each line does here because I did that in the factory example, if you’re confused, re-read the factory example.

app.service('myService', function($http, $q){
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
    _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
    return _finalUrl;
  }
});

Now, we’ll attach all of our methods that will be available in our controller to ‘this’.

app.service('myService', function($http, $q){
  var baseUrl = 'https://itunes.apple.com/search?term=';
  var _artist = '';
  var _finalUrl = '';

  var makeUrl = function(){
    _artist = _artist.split(' ').join('+');
    _finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
    return _finalUrl;
  }

  this.setArtist = function(artist){
    _artist = artist;
  }

  this.getArtist = function(){
    return _artist;
  }

  this.callItunes = function(){
    makeUrl();
    var deferred = $q.defer();
    $http({
      method: 'JSONP',
      url: _finalUrl
    }).success(function(data){
      deferred.resolve(data);
    }).error(function(){
      deferred.reject('There was an error')
    })
    return deferred.promise;
  }

});

Now just like in our factory, setArtist, getArtist, and callItunes will be available in whichever controller we pass myService into. Here’s the myService controller (which is almost exactly the same as our factory controller).

app.controller('myServiceCtrl', function($scope, myService){
  $scope.data = {};
  $scope.updateArtist = function(){
    myService.setArtist($scope.data.artist);
  };

  $scope.submitArtist = function(){
    myService.callItunes()
      .then(function(data){
        $scope.data.artistData = data;
      }, function(data){
        alert(data);
      })
  }
});

Like I mentioned before, once you really understand what ‘new’ does, Services are almost identical to factories in Angular.

To add to Kevin's answer, I find that in practice nearly all of your non-trivial Spring MVC applications will require an application context (as opposed to only the spring MVC dispatcher servlet context). It is in the application context that you should configure all non-web related concerns such as:

• Security
• Persistence
• Scheduled Tasks
• Others?

To make this a bit more concrete, here's an example of the Spring configuration I've used when setting up a modern (Spring version 4.1.2) Spring MVC application. Personally, I prefer to still use a WEB-INF/web.xml file but that's really the only xml configuration in sight.

As you can see, the web configuration is only a small part of the overall spring web application configuration. Most web applications I've worked with have many concerns that lie outside of the dispatcher servlet configuration that require a full-blown application context bootstrapped via the org.springframework.web.context.ContextLoaderListener in the web.xml.

I'd try the following steps:

1) Check if there is a Byte Order Mark

2) Check if the file is valid UTF8

3) Use the local "ANSI" codepage (ANSI as Microsoft defines it)

Step 2 works because most non ASCII sequences in codepages other that UTF8 are not valid UTF8.

Make sure you're using the correct SDK when compiling/running and also, make sure you use source/target 1.7.

Screenshot:

Use: context.clearRect(0, 0, canvas.width, canvas.height);

This is the fastest and most descriptive way to clear the entire canvas.

Do not use: canvas.width = canvas.width;

Resetting canvas.width resets all canvas state (e.g. transformations, lineWidth, strokeStyle, etc.), it is very slow (compared to clearRect), it doesn't work in all browsers, and it doesn't describe what you are actually trying to do.

Dealing with transformed coordinates

If you have modified the transformation matrix (e.g. using scale, rotate, or translate) then context.clearRect(0,0,canvas.width,canvas.height) will likely not clear the entire visible portion of the canvas.

The solution? Reset the transformation matrix prior to clearing the canvas:

// Store the current transformation matrix
context.save();

// Use the identity matrix while clearing the canvas
context.setTransform(1, 0, 0, 1, 0, 0);
context.clearRect(0, 0, canvas.width, canvas.height);

// Restore the transform
context.restore();

Edit: I've just done some profiling and (in Chrome) it is about 10% faster to clear a 300x150 (default size) canvas without resetting the transform. As the size of your canvas increases this difference drops.

That is already relatively insignificant, but in most cases you will be drawing considerably more than you are clearing and I believe this performance difference be irrelevant.

100000 iterations averaged 10 times:
1885ms to clear
2112ms to reset and clear

You can also use dplyr's distinct() function! It tends to be more efficient than alternative options, especially if you have loads of observations.

distinct_data <- dplyr::distinct(yourdata)

You must set the height of the container explicitly

#container {
    height:100%;
    width:100%;
    position:absolute; 
}

You need a Flask view that will receive POST data and an HTML form that will send it.

from flask import request

@app.route('/addRegion', methods=['POST'])
def addRegion():
    ...
    return (request.form['projectFilePath'])

<form action="{{ url_for('addRegion') }}" method="post">
    Project file path: <input type="text" name="projectFilePath"><br>
    <input type="submit" value="Submit">
</form>

span element is display:inline; by default you need to make it inline-block or block

Change your CSS to be like this

span.first_title {
    margin-top: 20px;
    margin-left: 12px;
    font-weight: bold;
    font-size:24px;
    color: #221461;
    /*The change*/
    display:inline-block; /*or display:block;*/
}

Just use the * before it:

set<unsigned long>::iterator it;
for (it = myset.begin(); it != myset.end(); ++it) {
    cout << *it;
}

This dereferences it and allows you to access the element the iterator is currently on.

If the data is a static or global variable, it is zero-filled by default, so just declare it myStruct _m;

If the data is a local variable or a heap-allocated zone, clear it with memset like:

memset(&m, 0, sizeof(myStruct));

Current compilers (e.g. recent versions of gcc) optimize that quite well in practice. This works only if all zero values (include null pointers and floating point zero) are represented as all zero bits, which is true on all platforms I know about (but the C standard permits implementations where this is false; I know no such implementation).

You could perhaps code myStruct m = {}; or myStruct m = {0}; (even if the first member of myStruct is not a scalar).

My feeling is that using memset for local structures is the best, and it conveys better the fact that at runtime, something has to be done (while usually, global and static data can be understood as initialized at compile time, without any cost at runtime).

Use the DO statement, a new option in version 9.0:

DO LANGUAGE plpgsql
$$
BEGIN
CREATE TABLE "Logs"."Events"
    (
        EventId BIGSERIAL NOT NULL PRIMARY KEY,
        PrimaryKeyId bigint NOT NULL,
        EventDateTime date NOT NULL DEFAULT(now()),
        Action varchar(12) NOT NULL,
        UserId integer NOT NULL REFERENCES "Office"."Users"(UserId),
        PrincipalUserId varchar(50) NOT NULL DEFAULT(user)
    );

    CREATE TABLE "Logs"."EventDetails"
    (
        EventDetailId BIGSERIAL NOT NULL PRIMARY KEY,
        EventId bigint NOT NULL REFERENCES "Logs"."Events"(EventId),
        Resource varchar(64) NOT NULL,
        OldVal varchar(4000) NOT NULL,
        NewVal varchar(4000) NOT NULL
    );

    RAISE NOTICE 'Task completed sucessfully.';    
END;
$$;

use Date.prototype.toLocaleTimeString() as documented here

please note the locale example en-US in the url.

It might be cleaner if you have a function, say called vprint, that checks the verbose flag for you. Then you just call your own vprint function any place you want optional verbosity.

This plagued me for over an hour.

If you're using the dataSrc option and column defs option, make sure they are in the correct locations. I had nested column defs in the ajax settings and lost way too much time figuring that out.

This is good:

This is not good:

Subtle difference, but real enough to cause hair loss.

The Stream API was designed to make it easy to write computations in a way that was abstracted away from how they would be executed, making switching between sequential and parallel easy.

However, just because its easy, doesn't mean its always a good idea, and in fact, it is a bad idea to just drop .parallel() all over the place simply because you can.

First, note that parallelism offers no benefits other than the possibility of faster execution when more cores are available. A parallel execution will always involve more work than a sequential one, because in addition to solving the problem, it also has to perform dispatching and coordinating of sub-tasks. The hope is that you'll be able to get to the answer faster by breaking up the work across multiple processors; whether this actually happens depends on a lot of things, including the size of your data set, how much computation you are doing on each element, the nature of the computation (specifically, does the processing of one element interact with processing of others?), the number of processors available, and the number of other tasks competing for those processors.

Further, note that parallelism also often exposes nondeterminism in the computation that is often hidden by sequential implementations; sometimes this doesn't matter, or can be mitigated by constraining the operations involved (i.e., reduction operators must be stateless and associative.)

In reality, sometimes parallelism will speed up your computation, sometimes it will not, and sometimes it will even slow it down. It is best to develop first using sequential execution and then apply parallelism where

(A) you know that there's actually benefit to increased performance and

(B) that it will actually deliver increased performance.

(A) is a business problem, not a technical one. If you are a performance expert, you'll usually be able to look at the code and determine (B), but the smart path is to measure. (And, don't even bother until you're convinced of (A); if the code is fast enough, better to apply your brain cycles elsewhere.)

The simplest performance model for parallelism is the "NQ" model, where N is the number of elements, and Q is the computation per element. In general, you need the product NQ to exceed some threshold before you start getting a performance benefit. For a low-Q problem like "add up numbers from 1 to N", you will generally see a breakeven between N=1000 and N=10000. With higher-Q problems, you'll see breakevens at lower thresholds.

But the reality is quite complicated. So until you achieve experthood, first identify when sequential processing is actually costing you something, and then measure if parallelism will help.

you can further improve the performance, chech this

From CityEntities c
Inner Join dbo.MtCity t0 on c.CodCity = t0.CodCity
Where c.Row Between @p0 + 1 AND @p0 + @p1
Order By c.Row Asc

if you will use the from in this way it will give better result:

From   dbo.MtCity  t0
   Inner Join  CityEntities c on c.CodCity = t0.CodCity

reason: because you are using the where class on the CityEntities table which will eliminate many record before joining the MtCity, so 100% sure it will increase the performance many fold...

Anyway answer by rodrigoelp is really helpfull.

Thanks

It doesn't quite work that way in Python. Python passes references to objects. Inside your function you have an object -- You're free to mutate that object (if possible). However, integers are immutable. One workaround is to pass the integer in a container which can be mutated:

def change(x):
    x[0] = 3

x = [1]
change(x)
print x

This is ugly/clumsy at best, but you're not going to do any better in Python. The reason is because in Python, assignment (=) takes whatever object is the result of the right hand side and binds it to whatever is on the left hand side *(or passes it to the appropriate function).

Understanding this, we can see why there is no way to change the value of an immutable object inside a function -- you can't change any of its attributes because it's immutable, and you can't just assign the "variable" a new value because then you're actually creating a new object (which is distinct from the old one) and giving it the name that the old object had in the local namespace.

Usually the workaround is to simply return the object that you want:

def multiply_by_2(x):
    return 2*x

x = 1
x = multiply_by_2(x)

*In the first example case above, 3 actually gets passed to x.__setitem__.

Like this

sleep(no_of_seconds)

Or you may pass other possible arguments like:

sleep(5.seconds)

sleep(5.minutes)

sleep(5.hours)

sleep(5.days)

I had to add !important to get it to work. I also made my own class button-primary-override.

.button-primary-override:hover, 
.button-primary-override:active,
.button-primary-override:focus,
.button-primary-override:visited{
    background-color: #42A5F5 !important;
    border-color: #42A5F5 !important;
    background-image: none !important;
    border: 0 !important;
}

(Sorry, can't add comments)

In Blaise's answer above, if you change:

@XmlJavaTypeAdapter(MapAdapter.class)
public Map<String, String> getMapProperty() {
    return mapProperty;
}

to:

@XmlJavaTypeAdapter(MapAdapter.class)
@XmlPath(".") // <<-- add this
public Map<String, String> getMapProperty() {
    return mapProperty;
}

then this should get rid of the <mapProperty> tag, and so give you:

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <map>
        <key>value</key>
        <key2>value2</key2>
    </map>
</root>

ALTERNATIVELY:

You can also change it to:

@XmlJavaTypeAdapter(MapAdapter.class)
@XmlAnyElement // <<-- add this
public Map<String, String> getMapProperty() {
    return mapProperty;
}

and then you can get rid of AdaptedMap altogether, and just change MapAdapter to marshall to a Document object directly. I've only tested this with marshalling, so there may be unmarshalling issues.

I'll try and find the time to knock up a full example of this, and edit this post accordingly.

To hide arrows and cross in a "time" input :

#inputId::-webkit-outer-spin-button,
#inputId::-webkit-inner-spin-button,
#inputId::-webkit-clear-button{
    -webkit-appearance: none;
    margin: 0;
}

git remote set-url origin git://new.location

(alternatively, open .git/config, look for [remote "origin"], and edit the url = line.

You can check it worked by examining the remotes:

git remote -v
# origin  git://new.location (fetch)
# origin  git://new.location (push)

Next time you push, you'll have to specify the new upstream branch, e.g.:

git push -u origin master

See also: GitHub: Changing a remote's URL

To ignore all untracked files in any submodule use the following command to ignore those changes.

git config --global diff.ignoreSubmodules dirty

It will add the following configuration option to your local git config:

[diff]
  ignoreSubmodules = dirty

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

0. Using nanoid third party library [NEW!]

A tiny, secure, URL-friendly, unique string ID generator for JavaScript

https://github.com/ai/nanoid

import { nanoid } from "nanoid";
const id = nanoid(48);

1. Base 64 Encoding with URL and Filename Safe Alphabet

Page 7 of RCF 4648 describes how to encode in base 64 with URL safety. You can use an existing library like base64url to do the job.

The function will be:

var crypto = require('crypto');
var base64url = require('base64url');

/** Sync */
function randomStringAsBase64Url(size) {
  return base64url(crypto.randomBytes(size));
}

Usage example:

randomStringAsBase64Url(20);
// Returns 'AXSGpLVjne_f7w5Xg-fWdoBwbfs' which is 27 characters length.

Note that the returned string length will not match with the size argument (size != final length).

2. Crypto random values from limited set of characters

Beware that with this solution the generated random string is not uniformly distributed.

You can also build a strong random string from a limited set of characters like that:

var crypto = require('crypto');

/** Sync */
function randomString(length, chars) {
  if (!chars) {
    throw new Error('Argument \'chars\' is undefined');
  }

  var charsLength = chars.length;
  if (charsLength > 256) {
    throw new Error('Argument \'chars\' should not have more than 256 characters'
      + ', otherwise unpredictability will be broken');
  }

  var randomBytes = crypto.randomBytes(length);
  var result = new Array(length);

  var cursor = 0;
  for (var i = 0; i < length; i++) {
    cursor += randomBytes[i];
    result[i] = chars[cursor % charsLength];
  }

  return result.join('');
}

/** Sync */
function randomAsciiString(length) {
  return randomString(length,
    'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789');
}

Usage example:

randomAsciiString(20);
// Returns 'rmRptK5niTSey7NlDk5y' which is 20 characters length.

randomString(20, 'ABCDEFG');
// Returns 'CCBAAGDGBBEGBDBECDCE' which is 20 characters length.

One way:

import os
os.listdir("/home/username/www/")

Another way:

glob.glob("/home/username/www/*")

Examples found here.

The glob.glob method above will not list hidden files.

Since I originally answered this question years ago, pathlib has been added to Python. My preferred way to list a directory now usually involves the iterdir method on Path objects:

from pathlib import Path
print(*Path("/home/username/www/").iterdir(), sep="\n")

If you are willing to put a container element around your image, a pure CSS solution is simple. You see, 99% height has no meaning when the parent element will extend vertically to contain its children. The parent needs to have a fixed height, say... the height of the viewport.

<!-- use a tall image to illustrate the problem -->
<div class='fill-screen'>
    <img class='make-it-fit' 
         src='https://upload.wikimedia.org/wikipedia/commons/f/f2/Leaning_Tower_of_Pisa.jpg'>
</div>

CSS

div.fill-screen {
    position: fixed;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    text-align: center;
}

img.make-it-fit {
    max-width: 99%;
    max-height: 99%;
}

Play with the fiddle.

So I wrote a function that would get the POST data from the php://input stream.

So the challenge here was switching to PUT, DELETE OR PATCH request method, and still obtain the post data that was sent with that request.

I'm sharing this maybe for someone with a similar challenge. The function below is what I came up with and it works. I hope it helps!

    /**
     * @method Post getPostData
     * @return array
     * 
     * Convert Content-Disposition to a post data
     */
    function getPostData() : array
    {
        // @var string $input
        $input = file_get_contents('php://input');

        // continue if $_POST is empty
        if (strlen($input) > 0 && count($_POST) == 0 || count($_POST) > 0) :

            $postsize = "---".sha1(strlen($input))."---";

            preg_match_all('/([-]{2,})([^\s]+)[\n|\s]{0,}/', $input, $match);

            // update input
            if (count($match) > 0) $input = preg_replace('/([-]{2,})([^\s]+)[\n|\s]{0,}/', '', $input);

            // extract the content-disposition
            preg_match_all("/(Content-Disposition: form-data; name=)+(.*)/m", $input, $matches);

            // let's get the keys
            if (count($matches) > 0 && count($matches[0]) > 0)
            {
                $keys = $matches[2];

                foreach ($keys as $index => $key) :
                    $key = trim($key);
                    $key = preg_replace('/^["]/','',$key);
                    $key = preg_replace('/["]$/','',$key);
                    $key = preg_replace('/[\s]/','',$key);
                    $keys[$index] = $key;
                endforeach;

                $input = preg_replace("/(Content-Disposition: form-data; name=)+(.*)/m", $postsize, $input);

                $input = preg_replace("/(Content-Length: )+([^\n]+)/im", '', $input);

                // now let's get key value
                $inputArr = explode($postsize, $input);

                // @var array $values
                $values = [];

                foreach ($inputArr as $index => $val) :
                    $val = preg_replace('/[\n]/','',$val);

                    if (preg_match('/[\S]/', $val)) $values[$index] = trim($val);

                endforeach;

                // now combine the key to the values
                $post = [];

                // @var array $value
                $value = [];

                // update value
                foreach ($values as $i => $val) $value[] = $val;

                // push to post
                foreach ($keys as $x => $key) $post[$key] = isset($value[$x]) ? $value[$x] : '';

                if (is_array($post)) :

                    $newPost = [];

                    foreach ($post as $key => $val) :

                        if (preg_match('/[\[]/', $key)) :

                            $k = substr($key, 0, strpos($key, '['));
                            $child = substr($key, strpos($key, '['));
                            $child = preg_replace('/[\[|\]]/','', $child);
                            $newPost[$k][$child] = $val;

                        else:

                            $newPost[$key] = $val;

                        endif;

                    endforeach;

                    $_POST = count($newPost) > 0 ? $newPost : $post;

                endif;
            }

        endif;

        // return post array
        return $_POST;
    }

• Linux: CTRL + F12
• Mac: Fn + CTRL + F12
• Windows: Left CTRL + F11 or Left CTRL + F12

This should do the trick:

public static int[] addPos(int[] a, int pos, int num) {
    int[] result = new int[a.length];
    for(int i = 0; i < pos; i++)
        result[i] = a[i];
    result[pos] = num;
    for(int i = pos + 1; i < a.length; i++)
        result[i] = a[i - 1];
    return result;
}

Where a is the original array, pos is the position of insertion, and num is the number to be inserted.

I was also facing the same issue But my issue was due to wrong credentials stored in my keyChain. So I solved by removing my old credentials from my keychain.

Be sure to test any solution across different Reader preferences. A site visitor may have their browser set to open the PDF in Reader/Acrobat as opposed to the browser, e.g., by disabling the Acrobat plugin in Firefox..

I can't be sure of my results, because I have two different Acrobat plugins that Firefox recognizes due to my having different versions of Adobe Acrobat and Adobe Reader, but it does appear that you at least need to test what happens if a website visitor has their browser set to not open the PDF in the browser. It could be quite annoying when they look at what appears to be an otherwise usable web page and their browser is nagging them to open a PDF file that they think they didn't request. In some cases, the PDF file spontaneously opened in Adobe Reader, not the browser, and in other cases the browser threw up a dialog saying the file didn't exist.

I ran into such mismatches with iframe and object both, different issues for different code.

This is for simple HTML code. I haven't tried the suggested frameworks.

The answer for git branch -r --contains <commit> works well for normal remote branches, but if the commit is only in the hidden head namespace that GitHub creates for PRs, you'll need a few more steps.

Say, if PR #42 was from deleted branch and that PR thread has the only reference to the commit on the repo, git branch -r doesn't know about PR #42 because refs like refs/pull/42/head aren't listed as a remote branch by default.

In .git/config for the [remote "origin"] section add a new line:

fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

(This gist has more context.)

Then when you git fetch you'll get all the PR branches, and when you run git branch -r --contains <commit> you'll see origin/pr/42 contains the commit.

Before explaining anything about if __name__ == '__main__' it is important to understand what __name__ is and what it does.

What is __name__?

__name__ is a DunderAlias - can be thought of as a global variable (accessible from modules) and works in a similar way to global.

It is a string (global as mentioned above) as indicated by type(__name__) (yielding <class 'str'>), and is an inbuilt standard for both Python 3 and Python 2 versions.

Where:

It can not only be used in scripts but can also be found in both the interpreter and modules/packages.

Interpreter:

>>> print(__name__)
__main__
>>>

Script:

test_file.py:

print(__name__)

Resulting in __main__

Module or package:

somefile.py:

def somefunction():
    print(__name__)

test_file.py:

import somefile
somefile.somefunction()

Resulting in somefile

Notice that when used in a package or module, __name__ takes the name of the file. The path of the actual module or package path is not given, but has its own DunderAlias __file__, that allows for this.

You should see that, where __name__, where it is the main file (or program) will always return __main__, and if it is a module/package, or anything that is running off some other Python script, will return the name of the file where it has originated from.

Practice:

Being a variable means that it's value can be overwritten ("can" does not mean "should"), overwriting the value of __name__ will result in a lack of readability. So do not do it, for any reason. If you need a variable define a new variable.

It is always assumed that the value of __name__ to be __main__ or the name of the file. Once again changing this default value will cause more confusion that it will do good, causing problems further down the line.

example:

>>> __name__ = 'Horrify' # Change default from __main__
>>> if __name__ == 'Horrify': print(__name__)
...
>>> else: print('Not Horrify')
...
Horrify
>>>

It is considered good practice in general to include the if __name__ == '__main__' in scripts.

Now to answer if __name__ == '__main__':

Now we know the behaviour of __name__ things become clearer:

An if is a flow control statement that contains the block of code will execute if the value given is true. We have seen that __name__ can take either __main__ or the file name it has been imported from.

This means that if __name__ is equal to __main__ then the file must be the main file and must actually be running (or it is the interpreter), not a module or package imported into the script.

If indeed __name__ does take the value of __main__ then whatever is in that block of code will execute.

This tells us that if the file running is the main file (or you are running from the interpreter directly) then that condition must execute. If it is a package then it should not, and the value will not be __main__.

Modules:

__name__ can also be used in modules to define the name of a module

Variants:

It is also possible to do other, less common but useful things with __name__, some I will show here:

Executing only if the file is a module or package:

if __name__ != '__main__':
    # Do some useful things 

Running one condition if the file is the main one and another if it is not:

if __name__ == '__main__':
    # Execute something
else:
    # Do some useful things

You can also use it to provide runnable help functions/utilities on packages and modules without the elaborate use of libraries.

It also allows modules to be run from the command line as main scripts, which can be also very useful.

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:

NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")

To be absolutely correct you should put all the names into the SAN field.

The CN field should contain a Subject Name not a domain name, but when the Netscape found out this SSL thing, they missed to define its greatest market. Simply there was not certificate field defined for the Server URL.

This was solved to put the domain into the CN field, and nowadays usage of the CN field is deprecated, but still widely used. The CN can hold only one domain name.

The general rules for this: CN - put here your main URL (for compatibility) SAN - put all your domain here, repeat the CN because its not in right place there, but its used for that...

If you found a correct implementation, the answers for your questions will be the followings:

• Has this setup a special meaning, or any [dis]advantages over setting both CNs? You cant set both CNs, because CN can hold only one name. You can make with 2 simple CN certificate instead one CN+SAN certificate, but you need 2 IP addresses for this.

• What happens on server-side if the other one, host.domain.tld, is being requested? It doesn't matter whats happen on server side.

In short: When a browser client connects to this server, then the browser sends encrypted packages, which are encrypted with the public key of the server. Server decrypts the package, and if server can decrypt, then it was encrypted for the server.

The server doesn't know anything from the client before decrypt, because only the IP address is not encrypted trough the connection. This is why you need 2 IPs for 2 certificates. (Forget SNI, there is too much XP out there still now.)

On client side the browser gets the CN, then the SAN until all of the are checked. If one of the names matches for the site, then the URL verification was done by the browser. (im not talking on the certificate verification, of course a lot of ocsp, crl, aia request and answers travels on the net every time.)

In python3 you can use urllib3 and shutil libraires. Download them by using pip or pip3 (Depending whether python3 is default or not)

pip3 install urllib3 shutil

Then run this code

import urllib.request
import shutil

url = "http://www.somewebsite.com/something.pdf"
output_file = "save_this_name.pdf"
with urllib.request.urlopen(url) as response, open(output_file, 'wb') as out_file:
    shutil.copyfileobj(response, out_file)

Note that you download urllib3 but use urllib in code

Do you have the SSH2 extension available?

Docs: http://www.php.net/manual/en/function.ssh2-exec.php

$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');

$stream = ssh2_exec($connection, '/usr/local/bin/php -i');

As of NP++ V6.2.3 (nor sure about older versions) simply:

1. Go menu -> Edit -> Line operations
2. Choose "Remove Empty Lines" or "Remove Empty Lines (Containing white spaces)" according to your needs.

Hope this helps to achieve goal in simple and yet fast way:)

You can do it as follow:

#include < iostream >

using namespace std;

int main () {

   string texts[] = {"Apple", "Banana", "Orange"};

   for( unsigned int a = 0; a < sizeof(texts) / 32; a++ ) { // 32 is the size of string data type

       cout << "value of a: " << texts[a] << endl;

   }


   return 0;

}

In your composer.json, you can put:

{
    "require": {
        "vendor/package": "version"
    }
}

then run composer install or composer update from the directory containing composer.json. Sometimes, for me, composer is hinky, so I'll start with composer clear-cache; rm -rf vendor; rm composer.lock before composer install to make sure it's getting fresh stuff.

Of course, as the other answers point out you can run the following from the terminal:

composer require vendor/package:version

And on versioning:

- Ecosia Search

You'll need to generate the SQL content dynamically:

declare @tablename varchar(50)

set @tablename = 'test'

declare @sql varchar(500)

set @sql = 'select * from ' + @tablename

exec (@sql)

You're trying to compare your working tree with a particular branch name, so you want this:

git diff master -- foo

Which is from this form of git-diff (see the git-diff manpage)

   git diff [--options] <commit> [--] [<path>...]
       This form is to view the changes you have in your working tree
       relative to the named <commit>. You can use HEAD to compare it with
       the latest commit, or a branch name to compare with the tip of a
       different branch.

FYI, there is also a --cached (aka --staged) option for viewing the diff of what you've staged, rather than everything in your working tree:

   git diff [--options] --cached [<commit>] [--] [<path>...]
       This form is to view the changes you staged for the next commit
       relative to the named <commit>.
       ...
       --staged is a synonym of --cached.

Run:

docker version

If docker is running you will see:

Client: Docker Engine - Community
 Version:           ...
 [omitted]

Server: Docker Engine - Community
 Engine:
  Version:          ...
 [omitted]

If docker is not running you will see:

Client: Docker Engine - Community
 Version:           ...
 [omitted]

Error response from daemon: Bad response from Docker engine

Try tracert to resolve the hostname. IE you have Ip address 8.8.8.8 so you would use; tracert 8.8.8.8

You can use bellow code:

import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.LogManager;

public class LogWriterUtility {
    Logger log;

    public LogWriterUtility(Class<?> clazz) {
        log = LogManager.getLogger(clazz);
    }

public void errorWithAnalysis( Exception exception) {

        String message="No Message on error";
        StackTraceElement[] stackTrace = exception.getStackTrace();
        if(stackTrace!=null && stackTrace.length>0) {
            message="";
            for (StackTraceElement e : stackTrace) {
                message += "\n" + e.toString();
            }
        }
        log.error(message);


    }

}

Here you can just call : LogWriterUtility.errorWithAnalysis( YOUR_EXCEPTION_INSTANCE);

It will print stackTrace into your log.

There is a drawback of shared pointer: shared_pointer can't handle the parent-child cycle dependency. Means if the parent class uses the object of child class using a shared pointer, in the same file if child class uses the object of the parent class. The shared pointer will be failed to destruct all objects, even shared pointer is not at all calling the destructor in cycle dependency scenario. basically shared pointer doesn't support the reference count mechanism.

This drawback we can overcome using weak_pointer.

You can call sortable on a <tbody> instead of on the individual rows.

    <tbody>
        <tr> 
            <td>1</td>
            <td>2</td>

If anyone is experiencing this same problem when reading a frame from a webcam [with code similar to "frame = cv2.VideoCapture(0)"] and work in Jupyter Notebook, you may try:

0. ensure previously tried code is not running already and restart Jupyter Notebook kernel

1. SEPARATE code "frame = cv2.VideoCapture(0)" in separate cell on place where it is [previous code put in cell above, code under put to cell down]

2. then run all the code above cell where is "frame = cv2.VideoCapture(0)"

3. then try run next cell with its only code "frame = cv2.VideoCapture(0)" - AND - till you will continue in executing other cells - ENSURE - that ASTERIX on the left side of this particular cell DISAPEAR and command order number appear instead - only then continue

4. now you can try execute the rest of your code as your camera input should not be empty anymore :-)

5. After end, ensure you close all your program and restart kernel to prepare it for another run

I had the same issue for PHP 7 version of missing mcrypt.

This worked for me.

sudo apt-get update
sudo apt-get install mcrypt php7.0-mcrypt
sudo apt-get upgrade
sudo service apache2 restart (if needed)

Modern Solution

The result is that the circle never gets distorted and the text stays exactly in the middle of the circle - vertically and horizontally.

.circle {
  background: gold;
  width: 40px; 
  height: 40px;
  border-radius: 50%;
  display: flex; /* or inline-flex */
  align-items: center; 
  justify-content: center;
}

<div class="circle">text</div>

Simple and easy to use. Enjoy!

If you don't need HTTPS and curl is not available on your system you could use fsockopen

This function opens a connection from which you can both read and write like you would do with a normal file handle.

In a servlet based artifact, such as @WebServlet, @WebFilter and @WebListener, you can grab a "plain vanilla" JSF @ManagedBean @RequestScoped by:

Bean bean = (Bean) request.getAttribute("beanName");

and @ManagedBean @SessionScoped by:

Bean bean = (Bean) request.getSession().getAttribute("beanName");

and @ManagedBean @ApplicationScoped by:

Bean bean = (Bean) getServletContext().getAttribute("beanName");

Note that this prerequires that the bean is already autocreated by JSF beforehand. Else these will return null. You'd then need to manually create the bean and use setAttribute("beanName", bean).

If you're able to use CDI @Named instead of the since JSF 2.3 deprecated @ManagedBean, then it's even more easy, particularly because you don't anymore need to manually create the beans:

@Inject
private Bean bean;

Note that this won't work when you're using @Named @ViewScoped because the bean can only be identified by JSF view state and that's only available when the FacesServlet has been invoked. So in a filter which runs before that, accessing an @Injected @ViewScoped will always throw ContextNotActiveException.

Only when you're inside @ManagedBean, then you can use @ManagedProperty:

@ManagedProperty("#{bean}")
private Bean bean;

Note that this doesn't work inside a @Named or @WebServlet or any other artifact. It really works inside @ManagedBean only.

If you're not inside a @ManagedBean, but the FacesContext is readily available (i.e. FacesContext#getCurrentInstance() doesn't return null), you can also use Application#evaluateExpressionGet():

FacesContext context = FacesContext.getCurrentInstance();
Bean bean = context.getApplication().evaluateExpressionGet(context, "#{beanName}", Bean.class);

which can be convenienced as follows:

@SuppressWarnings("unchecked")
public static <T> T findBean(String beanName) {
    FacesContext context = FacesContext.getCurrentInstance();
    return (T) context.getApplication().evaluateExpressionGet(context, "#{" + beanName + "}", Object.class);
}

and can be used as follows:

Bean bean = findBean("bean");

You can check with null or Number.

First, add a reference to Microsoft.VisualBasic in your application.

Then, use the following code:

bool b = Microsoft.VisualBasic.Information.IsNumeric("null");
bool c = Microsoft.VisualBasic.Information.IsNumeric("abc");

In the above, b and c should both be false.

Use <div style="position:fixed;bottom:0;height:auto;margin-top:40px;width:100%;text-align:center">I am footer</div>. Footer will not go upwards

To make this work work with all browsers including Chrome you need to make the callback function of sort() return -1,0 or 1.

see http://inderpreetsingh.com/2010/12/01/chromes-javascript-sort-array-function-is-different-yet-proper/

function sortUL(selector) {
    $(selector).children("li").sort(function(a, b) {
        var upA = $(a).text().toUpperCase();
        var upB = $(b).text().toUpperCase();
        return (upA < upB) ? -1 : (upA > upB) ? 1 : 0;
    }).appendTo(selector);
}
sortUL("ul.mylist");

There is no standard library function to do this, but it's not too hard to roll your own. There is an existing question on SO about doing this that was answered with source code.

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

You can try wiht TIMESTAMP(curdate(), curtime()) for use the current time.

The 2 domains mydomain.com and subdomain.mydomain.com can only share cookies if the domain is explicitly named in the Set-Cookie header. Otherwise, the scope of the cookie is restricted to the request host. (This is referred to as a "host-only cookie". See What is a host only cookie?)

For instance, if you sent the following header from subdomain.mydomain.com, then the cookie won't be sent for requests to mydomain.com:

Set-Cookie: name=value

However if you use the following, it will be usable on both domains:

Set-Cookie: name=value; domain=mydomain.com

This cookie will be sent for any subdomain of mydomain.com, including nested subdomains like subsub.subdomain.mydomain.com.

In RFC 2109, a domain without a leading dot meant that it could not be used on subdomains, and only a leading dot (.mydomain.com) would allow it to be used across multiple subdomains (but not the top-level domain, so what you ask was not possible in the older spec).

However, all modern browsers respect the newer specification RFC 6265, and will ignore any leading dot, meaning you can use the cookie on subdomains as well as the top-level domain.

In summary, if you set a cookie like the second example above from mydomain.com, it would be accessible by subdomain.mydomain.com, and vice versa. This can also be used to allow sub1.mydomain.com and sub2.mydomain.com to share cookies.

Here is a simple workaround in jQuery. You can implement it as a user script to apply it to every page you view.

$(function () {
  $('img').live('mouseover', function () {
    var img = $(this); // cache query
    if (img.title) {
      return;
    }
    img.attr('title', img.attr('alt'));
  });
});

I have also implemented this as a Chrome extension called alt. Because it uses jQuery.live, it works with dynamically loaded content, too. I have retired this extension and removed it from the Chrome store.

In the case of DSE (DataStax Cassandra & Spark) The following location needs to be added to PYTHONPATH

export PYTHONPATH=/usr/share/dse/resources/spark/python:$PYTHONPATH

Then use the dse pyspark to get the modules in path.

Just an update.

Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.

GitHub shorthand

$ bower install desandro/masonry

I had the same issue and did all the tips including Gmail setting (e.g. less secure apps access) with no luck. But finally when I changed password to something different, for some reason it worked! FYI, the initial password did not have any special characters.

This works for me.

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new 

StreamWriter(httpWebRequest.GetRequestStream()))
{
    string json = new JavaScriptSerializer().Serialize(new
                {
                    Username = "myusername",
                    Password = "password"
                });

    streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
    var result = streamReader.ReadToEnd();
}

Personally, I do the following:

session_start();
setcookie(session_name(), '', 100);
session_unset();
session_destroy();
$_SESSION = array();

That way, it kills the cookie, destroys all data stored internally, and destroys the current instance of the session information (which is ignored by session_destroy).

1) Download the JDBC Driver here.

2) unzip the file and go to sqljdbc_version\fra\auth\x86 or \x64
3) copy the sqljdbc_auth.dll to C:\Program Files\Java\jre_Version\bin
4) Finally restart eclipse

If you have the size of the image, why don't you set the frame.size of the image view to be of this size?

EDIT----

Ok, so seeing your comment I propose this:

UIImageView *imageView;
//so let's say you're image view size is set to the maximum size you want

CGFloat maxWidth = imageView.frame.size.width;
CGFloat maxHeight = imageView.frame.size.height;

CGFloat viewRatio = maxWidth / maxHeight;
CGFloat imageRatio = image.size.height / image.size.width;

if (imageRatio > viewRatio) {
    CGFloat imageViewHeight = round(maxWidth * imageRatio);
    imageView.frame = CGRectMake(0, ceil((self.bounds.size.height - imageViewHeight) / 2.f), maxWidth, imageViewHeight);
}
else if (imageRatio < viewRatio) {
    CGFloat imageViewWidth = roundf(maxHeight / imageRatio);
    imageView.frame = CGRectMake(ceil((maxWidth - imageViewWidth) / 2.f), 0, imageViewWidth, maxHeight);
} else {
    //your image view is already at the good size
}

This code will resize your image view to its image ratio, and also position the image view to the same centre as your "default" position.

PS: I hope you're setting imageView.layer.shouldRasterise = YES and imageView.layer.rasterizationScale = [UIScreen mainScreen].scale;

if you're using CALayer shadow effect ;) It will greatly improve the performance of your UI.

Check http://msdn.microsoft.com/en-us/library/system.iformatprovider.aspx for the API.

If any Null value exists inside aggregate function you will face this issue. Instead of below code

 SELECT Count(closed)
  FROM   ticket
  WHERE  assigned_to = c.user_id
  AND closed IS NULL

use like

SELECT Count(ISNULL(closed, 0))
  FROM   ticket
  WHERE  assigned_to = c.user_id
  AND closed IS NULL

Using shell/unix tools

1. curl 'http://$artiserver/artifactory/api/storage/$repokey/$path/$version/?lastModified'

The above command responds with a JSON with two elements - "uri" and "lastModified"

2. Fetching the link in the uri returns another JSON which has the "downloadUri" of the artifact.

3. Fetch the link in the "downloadUri" and you have the latest artefact.

Using Jenkins Artifactory plugin

(Requires Pro) to resolve and download latest artifact, if Jenkins Artifactory plugin was used to publish to artifactory in another job:

1. Select Generic Artifactory Integration
2. Use Resolved Artifacts as ${repokey}:**/${component}*.jar;status=${STATUS}@${PUBLISH_BUILDJOB}#LATEST=>${targetDir}

$('.someclass').length

You could also use:

$('.someclass').size()

which is functionally equivalent, but the former is preferred. In fact, the latter is now deprecated and shouldn't be used in any new development.

Property order in normal Objects is a complex subject in Javascript.

While in ES5 explicitly no order has been specified, ES2015 has an order in certain cases. Given is the following object:

o = Object.create(null, {
  m: {value: function() {}, enumerable: true},
  "2": {value: "2", enumerable: true},
  "b": {value: "b", enumerable: true},
  0: {value: 0, enumerable: true},
  [Symbol()]: {value: "sym", enumerable: true},
  "1": {value: "1", enumerable: true},
  "a": {value: "a", enumerable: true},
});

This results in the following order (in certain cases):

Object {
  0: 0,
  1: "1",
  2: "2",
  b: "b",
  a: "a",
  m: function() {},
  Symbol(): "sym"
}

1. integer-like keys in ascending order
2. normal keys in insertion order
3. Symbols in insertion order

Thus, there are three segments, which may alter the insertion order (as happened in the example). And integer-like keys don't stick to the insertion order at all.

The question is, for what methods this order is guaranteed in the ES2015 spec?

The following methods guarantee the order shown:

• Object.assign
• Object.defineProperties
• Object.getOwnPropertyNames
• Object.getOwnPropertySymbols
• Reflect.ownKeys

The following methods/loops guarantee no order at all:

• Object.keys
• for..in
• JSON.parse
• JSON.stringify

Conclusion: Even in ES2015 you shouldn't rely on the property order of normal objects in Javascript. It is prone to errors. Use Map instead.

It does not meet your cloning requirement, but it seems simpler than many answers to do:

Array NewArray = new ArraySegment(oldArray,BeginIndex , int Count).ToArray();

You can try with

import { Router, ActivatedRoute} from '@angular/router';    

constructor(private router: Router, private activatedRoute:ActivatedRoute) {
console.log(activatedRoute.snapshot.url)  // array of states
console.log(activatedRoute.snapshot.url[0].path) }

Alternative ways

router.location.path();   this works only in browser console. 

window.location.pathname which gives the path name.

Another solution could be use the uncommit command to exclude specific file from current commit.

hg uncommit [file/directory]

This is very helpful when you want to keep current commit and deselect some files from commit (especially helpful for files/directories have been deleted).

Mark the test with the ExpectedExceptionAttribute (this is the term in NUnit or MSTest; users of other unit testing frameworks may need to translate).

numline = len(file_read.readlines())

This depends on how you want the # of months to be defined. Answer this questions: 'What is difference in months: Feb 15, 2008 - Mar 12, 2009'. Is it defined by clear cut # of days which depends on leap years- what month it is, or same day of previous month = 1 month.

A calculation for Days:

Feb 15 -> 29 (leap year) = 14 Mar 1, 2008 + 365 = Mar 1, 2009. Mar 1 -> Mar 12 = 12 days. 14 + 365 + 12 = 391 days. Total = 391 days / (avg days in month = 30) = 13.03333

A calculation of months:

Feb 15 2008 - Feb 15 2009 = 12 Feb 15 -> Mar 12 = less than 1 month Total = 12 months, or 13 if feb 15 - mar 12 is considered 'the past month'

foreach ($array as $value => $name) {
     echo '<option value="' . htmlentities($value) . '"' . (($_GET['sel'] === $value) ? ' selected="selected"') . '>' . htmlentities($name) . '</option>';
}

This is fairly neat, and, I think, self-explanatory.

From http://www.dba-oracle.com/t_isnumeric.htm

LENGTH(TRIM(TRANSLATE(, ' +-.0123456789', ' '))) is null

If there is anything left in the string after the TRIM it must be non-numeric characters.

Assume you make the access_token last very long, and don't have refresh_token, so in one day, hacker get this access_token and he can access all protected resources!

But if you have refresh_token, the access_token's live time is short, so the hacker is hard to hack your access_token because it will be invalid after short period of time. Access_token can only be retrieved back by using not only refresh_token but also by client_id and client_secret, which hacker doesn't have.

Do not confuse variable tab-width with variable tab-stop-list. The former is used for the display of literal TAB characters. The latter controls what characters are inserted when you press the TAB character in certain modes.

-- GNU Emacs Manual

(customize-variable (quote tab-stop-list))

or add tab-stop-list entry to custom-set-variables in .emacs file:

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(tab-stop-list (quote (4 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 100 104 108 112 116 120))))

Another way to edit the tab behavior is with with M-x edit-tab-stops.

See the GNU Emacs Manual on Tab Stops for more information on edit-tab-stops.

A list of assemblies is available at Assemblies in the .NET Framework Client Profile on MSDN (the list is too long to include here).

If you're more interested in features, .NET Framework Client Profile on MSDN lists the following as being included:

• ClickOnce
• Windows Forms
• Windows Presentation Foundation (WPF)
• Windows Communication Foundation (WCF)
• Entity Framework
• Windows Workflow Foundation
• Speech
• XSLT support
• LINQ to SQL
• Runtime design libraries for Entity Framework and WCF Data Services
• Managed Extensibility Framework (MEF)
• Dynamic types
• Parallel-programming features, such as Task Parallel Library (TPL), Parallel LINQ (PLINQ), and Coordination Data Structures (CDS)

And the following as not being included:

• ASP.NET
• Advanced Windows Communication Foundation (WCF) functionality
• .NET Framework Data Provider for Oracle
• MSBuild for compiling

var option_user_selection = document.getElementById("maincourse").options[document.getElementById("maincourse").selectedIndex ].text

You can implement this functionality like this
Firstly, using the ls command pointed to the targeted directory. Later using find command filter the result from it. From your case, it sounds like - always the filename starts with a word file***.txt

ls /some/path/here | find . -name 'file*.txt'   (* represents some wild card search)

sh  -n   script-name 

Run this. If there are any syntax errors in the script, then it returns the same error message. If there are no errors, then it comes out without giving any message. You can check immediately by using echo $?, which will return 0 confirming successful without any mistake.

It worked for me well. I ran on Linux OS, Bash Shell.

In one of my projects I run tests against Python 2 and 3. For that I wrote a small script which starts a local server independently:

$ python -m $(python -c 'import sys; print("http.server" if sys.version_info[:2] > (2,7) else "SimpleHTTPServer")')
Serving HTTP on 0.0.0.0 port 8000 ...

As an alias:

$ alias serve="python -m $(python -c 'import sys; print("http.server" if sys.version_info[:2] > (2,7) else "SimpleHTTPServer")')"
$ serve
Serving HTTP on 0.0.0.0 port 8000 ...

Please note that I control my Python version via conda environments, because of that I can use python instead of python3 for using Python 3.

Many years late, but I just needed to do this and didn't like any of the solutions posted... So I made one up, all thanks to the magic of (SpongeBob rainbow hands gesture) "Evaluate()"!

Evaluate("IsError(" & vSheetName & "!1:1)")

Returns TRUE if Sheet does NOT exist; FALSE if sheet DOES exist. You can substitute whatever range you like for "1:1", but I advise against using a single cell, cuz if it contains an error (eg, #N/A), it will return True.

Some of the answers here haven't really helped.

People are showing you how to find stuff, but now how to replace it.

I just had a look, and it looks like it's Ctrl+H for replace, then you get the find dialog as well as a replace dialog. This worked for me.

For me only WifiManager.NETWORK_STATE_CHANGED_ACTION works.

Register a broadcast receiver:

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
registerReceiver(broadcastReceiver, intentFilter);

and receive:

@Override
public void onReceive(Context context, Intent intent) {

    final String action = intent.getAction();

    if(action.equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)){
        NetworkInfo info = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
        boolean connected = info.isConnected();

        //call your method
    }      
}

I think you want to use typeof() here:

function f(id, parameters, callback) {
  console.log(typeof(parameters)+" "+typeof(callback));
}

f("hi", {"a":"boo"}, f); //prints "object function"
f("hi", f, {"a":"boo"}); //prints "function object"

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

System.out.println(Name + " " + Income);

Is that what you mean? That will put a space between the name and the income?

the conversion from 1970,1,1 needs the double rounded to zero decimal places i thinks

DateTime d1 = new DateTime(1970, 1, 1);
DateTime d2 = dt.ToUniversalTime();
TimeSpan ts = new TimeSpan(d2.Ticks - d1.Ticks);
return Math.Round( ts.TotalMilliseconds,0);

on the client side i use

new Date(+data.replace(/\D/g, ''));

There are two things to remember here. One is to add the -PassThru argument and two is to add the -Wait argument. You need to add the wait argument because of this defect: http://connect.microsoft.com/PowerShell/feedback/details/520554/start-process-does-not-return-exitcode-property

-PassThru [<SwitchParameter>]
    Returns a process object for each process that the cmdlet started. By d
    efault, this cmdlet does not generate any output.

Once you do this a process object is passed back and you can look at the ExitCode property of that object. Here is an example:

$process = start-process ping.exe -windowstyle Hidden -ArgumentList "-n 1 -w 127.0.0.1" -PassThru -Wait
$process.ExitCode

# This will print 1

If you run it without -PassThru or -Wait, it will print out nothing.

The same answer is here: How do I run a Windows installer and get a succeed/fail value in PowerShell?

I came across this problem because my cols exceeded the row grid length (> 12)

A solution using 100% Bootstrap 4:

Since the rows in Bootstrap are already display: flex

You just need to add flex-fill to the Col, and h-100 to the container and any children.

Pen here: https://codepen.io/joshkopecek/pen/Exjdgjo

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">

    <div class="col-4 hidden-md-down flex-fill" id="yellow">
      XXXX
    </div>

    <div id="blue" class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8 h-100">
      Form Goes Here
    </div>

    <div id="green" class="col-10 col-sm-10 col-md-10 col-lg-8 col-xl-8 h-100">
      Another form
    </div>
  </div>
</div>

Per the docs, replace returns the new string - it does not modify the string you pass it.

var tt="88,9827";
tt = tt.replace(/,/g, '.');
^^^^
alert(tt);

For a binary search tree, an inorder traversal will return elements ... in order.

Just do an inorder traversal and stop after traversing k elements.

There is a comprehensive list of tools on the PostgreSQL Wiki:

https://wiki.postgresql.org/wiki/PostgreSQL_Clients

And of course PostgreSQL itself comes with pgAdmin, a GUI tool for accessing Postgres databases.

While that particular idiom is common, even more common is for people to use = when they mean ==. The convention when you really mean the = is to use an extra layer of parentheses:

while ((list = list->next)) { // yes, it's an assignment

When should we use one over the other?

The decision is a trade-off between compatibility and API access.

Use a .NET Standard library when you want to increase the number of applications that will be compatible with your library, and you are okay with a decrease in the .NET API surface area your library can access.

Use a .NET Core library when you want to increase the .NET API surface area your library can access, and you are okay with allowing only .NET Core applications to be compatible with your library.

For example, a library that targets .NET Standard 1.3 will be compatible with applications that target .NET Framework 4.6, .NET Core 1.0, Universal Windows Platform 10.0, and any other platform that supports .NET Standard 1.3. The library will not have access to some parts of the .NET API, though. For instance, the Microsoft.NETCore.CoreCLR package is compatible with .NET Core, but not with .NET Standard.

What is the difference between Class Library (.NET Standard) and Class Library (.NET Core)?

Compatibility: Libraries that target .NET Standard will run on any .NET Standard compliant runtime, such as .NET Core, .NET Framework, Mono/Xamarin. On the other hand, libraries that target .NET Core can only run on the .NET Core runtime.

API Surface Area: .NET Standard libraries come with everything in NETStandard.Library, whereas .NET Core libraries come with everything in Microsoft.NETCore.App. The latter includes approximately 20 additional libraries, some of which we can add manually to our .NET Standard library (such as System.Threading.Thread) and some of which are not compatible with the .NET Standard (such as Microsoft.NETCore.CoreCLR).

Also, .NET Core libraries specify a runtime and come with an application model. That's important, for instance, to make unit test class libraries runnable.

Why do both exist?

Ignoring libraries for a moment, the reason that .NET Standard exists is for portability; it defines a set of APIs that .NET platforms agree to implement. Any platform that implements a .NET Standard is compatible with libraries that target that .NET Standard. One of those compatible platforms is .NET Core.

Coming back to libraries, the .NET Standard library templates exist to run on multiple runtimes (at the expense of API surface area). Conversely, the .NET Core library templates exist to access more API surface area (at the expense of compatibility) and to specify a platform against which to build an executable.

Here is an interactive matrix that shows which .NET Standard supports which .NET implementation(s) and how much API surface area is available.

var date = new Date();
var year = date.getFullYear();
var month = date.getMonth() + 1;
month = (month < 10 ? "0" : "") + month;
var hour = date.getHours();
hour = (hour < 10 ? "0" : "") + hour;
var day  = date.getDate();
day = (hour > 12 ? "" : "") + day - 1;
day = (day < 10 ? "0" : "") + day;
x = ":"
console.log( month + x + day + x + year )

It will display the date in the month, day, then the year

This is an old problem with some good information. But what I just found is that using a FQDN turns off the Compat mode in IE 9 - 11. Example. I have the compat problem with
http://lrmstst01:8080/JavaWeb/login.do
but the problems go away with
http://lrmstst01.mydomain.int:8080/JavaWeb/login.do
NB: The .int is part of our internal domain

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

We can add an extension to create an empty list

    public static IEnumerable<T> Nullable<T>(this IEnumerable<T> obj)
    {
        if (obj == null)
            return new List<T>();
        else
            return obj;
    }

And use like this

foreach (model in models.Nullable())
{
    ....
}

Redirect the output to a file like this:

./a.sh > somefile 2>&1 &

This will redirect both stdout and stderr to the same file. If you want to redirect stdout and stderr to two different files use this:

./a.sh > stdoutfile 2> stderrfile &

You can use /dev/null as one or both of the files if you don't care about the stdout and/or stderr.

See bash manpage for details about redirections.

This code worked for me:

ListBox1.Items.RemoveAt(ListBox1.SelectedIndex)

if you dont have apparmor or selinux issues, but still get errorcode 13's:

mysql must be able to access the full path. I.e. all folders must be mysql accessible, not just the one you intend in pointing to.

example, you try using this in your mysql configuration: tmp = /some/folder/on/disk

# will work, as user root:
mkdir -p /some/folder/on/disk
chown -R mysql:mysql /some

# will not work, also as user root:
mkdir -p /some/folder/on/disk
chown -R mysql:mysql /some/folder/on/disk

You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :

BEGIN TRANSACTION

update A
set A.ORG_NAME =  @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID

update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
    on B.ORG_ID = A.ORG_ID
    and A.ORG_ID = @ORG_ID

COMMIT

Don't modify strings.

Work with them as lists; turn them into strings only when needed.

>>> s = list("Hello zorld")
>>> s
['H', 'e', 'l', 'l', 'o', ' ', 'z', 'o', 'r', 'l', 'd']
>>> s[6] = 'W'
>>> s
['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']
>>> "".join(s)
'Hello World'

Python strings are immutable (i.e. they can't be modified). There are a lot of reasons for this. Use lists until you have no choice, only then turn them into strings.

First, you need the permission in your AndroidManifest.xml:

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

Also, in yourAndroidManifest.xml, define your service and listen for the BOOT_COMPLETED action:

<service android:name=".MyService" android:label="My Service">
    <intent-filter>
        <action android:name="com.myapp.MyService" />
    </intent-filter>
</service>

<receiver
    android:name=".receiver.StartMyServiceAtBootReceiver"
    android:label="StartMyServiceAtBootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

Then you need to define the receiver that will get the BOOT_COMPLETED action and start your service.

public class StartMyServiceAtBootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            Intent serviceIntent = new Intent(context, MyService.class);
            context.startService(serviceIntent);
        }
    }
}

And now your service should be running when the phone starts up.

I solved the problem. I made mistake in setData(Uri) and setType(String).

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

That is correct now, my auto-update is working. Thanks for help. =)

Edit 20.7.2016:

After a long time, I had to use this way of updating again in another project. I encountered a number of problems with old solution. A lot of things have changed in that time, so I had to do this with a different approach. Here is the code:

    //get destination to update file and set Uri
    //TODO: First I wanted to store my update .apk file on internal storage for my app but apparently android does not allow you to open and install
    //aplication with existing package from there. So for me, alternative solution is Download directory in external storage. If there is better
    //solution, please inform us in comment
    String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
    String fileName = "AppName.apk";
    destination += fileName;
    final Uri uri = Uri.parse("file://" + destination);

    //Delete update file if exists
    File file = new File(destination);
    if (file.exists())
    //file.delete() - test this, I think sometimes it doesnt work
        file.delete();

    //get url of app on server
    String url = Main.this.getString(R.string.update_app_url);

    //set downloadmanager
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
    request.setDescription(Main.this.getString(R.string.notification_description));
    request.setTitle(Main.this.getString(R.string.app_name));

    //set destination
    request.setDestinationUri(uri);

    // get download service and enqueue file
    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    final long downloadId = manager.enqueue(request);

    //set BroadcastReceiver to install app when .apk is downloaded
    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            Intent install = new Intent(Intent.ACTION_VIEW);
            install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            install.setDataAndType(uri,
                    manager.getMimeTypeForDownloadedFile(downloadId));
            startActivity(install);

            unregisterReceiver(this);
            finish();
        }
    };
    //register receiver for when .apk download is compete
    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

You don't need to do an explicit typedef for classes and structs. What do you need the typedef for? Further, the typedef after a template<...> is syntactically wrong. Simply use:

template <class T>
struct array {
  size_t x;
  T *ary;
} ;

First of all, let's try to make your code a little simpler:

// No need to create a circle unless it is clearly necessary to
// demonstrate the problem

// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());

Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:

int main() {
    delete new T();
}

This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:

In function 'int main()':
Line 2: error: expected type-specifier before 'T'

Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f.

I can't comment on the accepted answer, due to low reputation. However, I would like to add, this behavior is by design. The NodeManager is killing your container. It sounds like you are trying to use hadoop streaming which is running as a child process of the map-reduce task. The NodeManager monitors the entire process tree of the task and if it eats up more memory than the maximum set in mapreduce.map.memory.mb or mapreduce.reduce.memory.mb respectively, we would expect the Nodemanager to kill the task, otherwise your task is stealing memory belonging to other containers, which you don't want.

$.ajax({    
    type: 'POST',  
    url: 'test.php',  
    data:$("#Test-form").serialize(),  
    dataType:'json',
     beforeSend:function(xhr, settings){
     settings.data += '&moreinfo=MoreData';
     },
    success:function(data){
            //  json response  
    },
    error: function(data) { 
        // if error occured
    }
    });

mklement0's answer is great, but I have some small tweaks.

It seems like a good idea to explicitly specify bash's encoding when using iconv. Also, we should prepend a byte-order mark (even though the unicode standard doesn't recommend it) because there can be legitimate confusions between UTF-8 and ASCII without a byte-order mark. Unfortunately, iconv doesn't prepend a byte-order mark when you explicitly specify an endianness (UTF-16BE or UTF-16LE), so we need to use UTF-16, which uses platform-specific endianness, and then use file --mime-encoding to discover the true endianness iconv used.

(I uppercase all my encodings because when you list all of iconv's supported encodings with iconv -l they are all uppercase.)

# Find out MY_FILE's encoding
# We'll convert back to this at the end
FILE_ENCODING="$( file --brief --mime-encoding MY_FILE )"
# Find out bash's encoding, with which we should encode
# MY_FILE so sed doesn't fail with 
# sed: RE error: illegal byte sequence
BASH_ENCODING="$( locale charmap | tr [:lower:] [:upper:] )"
# Convert to UTF-16 (unknown endianness) so iconv ensures
# we have a byte-order mark
iconv -f "$FILE_ENCODING" -t UTF-16 MY_FILE > MY_FILE.utf16_encoding
# Whether we're using UTF-16BE or UTF-16LE
UTF16_ENCODING="$( file --brief --mime-encoding MY_FILE.utf16_encoding )"
# Now we can use MY_FILE.bash_encoding with sed
iconv -f "$UTF16_ENCODING" -t "$BASH_ENCODING" MY_FILE.utf16_encoding > MY_FILE.bash_encoding
# sed!
sed 's/.*/&/' MY_FILE.bash_encoding > MY_FILE_SEDDED.bash_encoding
# now convert MY_FILE_SEDDED.bash_encoding back to its original encoding
iconv -f "$BASH_ENCODING" -t "$FILE_ENCODING" MY_FILE_SEDDED.bash_encoding > MY_FILE_SEDDED
# Now MY_FILE_SEDDED has been processed by sed, and is in the same encoding as MY_FILE

Python 3

In Python 3.x basestring is not available anymore, as str is the sole string type (with the semantics of Python 2.x's unicode).

So the check in Python 3.x is just:

isinstance(obj_to_test, str)

This follows the fix of the official 2to3 conversion tool: converting basestring to str.

Since WP 2.6.0 you can use plugins_url() method.

I managed this with a css class in my app.css

.fill-window {
    height: 100%;
    position: absolute;
    left: 0;
    width: 100%;
    overflow: hidden;
}

Apply it to your root element in your render() method

render() {
   return ( <div className="fill-window">{content}</div> );
}

Or inline

render() {
   return (
      <div style={{ height: '100%', position: 'absolute', left: '0px', width: '100%', overflow: 'hidden'}}>
          {content}
      </div>
   );
}

If you already have pods which are recreated, think to delete all deployments first

kubectl delete -n *NAMESPACE deployment *DEPLOYMENT

Just replace the NAMSPACE and the DEPLOYMENT to corresponding ones, you can get all deployments information by the following command

kubectl get deployments --all-namespaces

This worked for me:

exclude: [/bower_components/, /node_modules/]

module.loaders

A array of automatically applied loaders.

Each item can have these properties:

test: A condition that must be met

exclude: A condition that must not be met

include: A condition that must be met

loader: A string of "!" separated loaders

loaders: A array of loaders as string

A condition can be a RegExp, an absolute path start, or an array of one of these combined with "and".

See http://webpack.github.io/docs/configuration.html#module-loaders

update

• If you use the router you can use lifecycle hooks or resolvers to delay navigation until the data arrived. https://angular.io/guide/router#milestone-5-route-guards

• To load data before the initial rendering of the root component APP_INITIALIZER can be used How to pass parameters rendered from backend to angular2 bootstrap method

original

When console.log(this.ev) is executed after this.fetchEvent();, this doesn't mean the fetchEvent() call is done, this only means that it is scheduled. When console.log(this.ev) is executed, the call to the server is not even made and of course has not yet returned a value.

Change fetchEvent() to return a Promise

     fetchEvent(){
        return  this._apiService.get.event(this.eventId).then(event => {
            this.ev = event;
            console.log(event); // Has a value
            console.log(this.ev); // Has a value
        });
     }

change ngOnInit() to wait for the Promise to complete

    ngOnInit() {
        this.fetchEvent().then(() =>
        console.log(this.ev)); // Now has value;
    }

This actually won't buy you much for your use case.

My suggestion: Wrap your entire template in an <div *ngIf="isDataAvailable"> (template content) </div>

and in ngOnInit()

    isDataAvailable:boolean = false;

    ngOnInit() {
        this.fetchEvent().then(() =>
        this.isDataAvailable = true); // Now has value;
    }

The error tells you EXACTLY what the problem is (and running in the debugger or reading the stack trace will tell you exactly where the problem is):

C# Collection was modified; enumeration operation may not execute.

Your problem is the loop

foreach (KeyValuePair<int, int> kvp in rankings) {
    //
}

wherein you modify the collection rankings. In particular, the offensive line is

rankings[kvp.Key] = rankings[kvp.Key] + 4;

Before you enter the loop, add the following line:

var listOfRankingsToModify = new List<int>();

Replace the offending line with

listOfRankingsToModify.Add(kvp.Key);

and after you exit the loop

foreach(var key in listOfRankingsToModify) {
    rankings[key] = rankings[key] + 4;
}

That is, record what changes you need to make, and make them without iterating over the collection that you need to modify.

I have created a responsive sample that works well for me and I find it to be quite simple have a look at my carousel-fill:

.carousel-fill {
    height: -o-calc(100vh - 165px) !important;
    height: -webkit-calc(100vh - 165px) !important;
    height: -moz-calc(100vh - 165px) !important;
    height: calc(100vh - 165px) !important;
    width: auto !important;
    overflow: hidden;
    display: inline-block;
    text-align: center;
}

.carousel-item {
    text-align: center !important;
}

my navigation height+footer are a hair less then 165px so that value works for me. take off a value that fits for you, I overrdide the .carousel-item from bootstrap so make sure by videos are centered.

my carousel looks like this, note the "carousel-fill" on the video tag.

I was having the same problem, and solved it by replacing Manifest.permission.READ_PHONE_STATE with android.Manifest.permission.READ_PHONE_STATE.

If you have access to your apache install and trust third-party code, you can use the apache upload progress module (if you use apache; there's also a nginx upload progress module).

Otherwise, you'd have to write a script that you can hit out of band to request the status of the file (checking the filesize of the tmp file for instance).

There's some work going on in firefox 3 I believe to add upload progress support to the browser, but that's not going to get into all the browsers and be widely adopted for a while (more's the pity).

I think that your JAVA_HOME should point to

C:\Program Files\Java\jdk1.6.0_25

instead of

C:\Program Files\Java\jdk1.6.0_25\bin

That is, without the bin folder.

UPDATE

That new error appears to me if I set the JAVA_HOME with the quotes, like you did. Are you using quotation marks? If so, remove them.

Use Ctrl-N to get a list of word suggestions while in insert mode. Type :help i_CTRL-N to see Vim's documentation on this functionality.

Here is an example of importing the Python dictionary into Vim.

This is the simple solution may work for you.

Check this solution

$('form').on('submit', function (e) {
e.preventDefault();
var emailBox=$("#email");
var passBox=$("#password");
if (!emailBox.val() || !passBox.val()) {
    $(".validationText").text("Please Enter Value").show();
}
else if(!IsEmail(emailBox.val()))
{
    emailBox.prev().text("Invalid E-mail").show();
}
$("input#email, input#password").focus(function(){
    $(this).prev(".validationText").hide();
});});

Also you can bind to the public static members of the enum directly by using reflection:

typeof(Suit).GetMembers(BindingFlags.Public | BindingFlags.Static)
    .ToList().ForEach(x => DoSomething(x.Name));

For me, I was only able to get it to work by using "." in the server name field; was banging away for awhile trying different combos of the user name and server name. Note that during install of the server (ie this file: SQLEXPR_x64_ENU.exe) i checked default instance which defaults the name to MSSQLSERVER; the above high voted answers might be best used for separate named (ie when you need more than 1) server instances.

both of these videos helped me out:

• use dot for server name: https://www.youtube.com/watch?v=DLrxFXXeLFk

                " where f.creationDate >= ? and f.creationDate < ? and b.bar = ?";
        return getHibernateTemplate().find(queryString, new Object[] {startDate, endDate, bar});

From: http://nginx.org/r/large_client_header_buffers

Syntax: large_client_header_buffers number size ;
Default: large_client_header_buffers 4 8k;
Context: http, server

Sets the maximum number and size of buffers used for reading large client request header. A request line cannot exceed the size of one buffer, or the 414 (Request-URI Too Large) error is returned to the client. A request header field cannot exceed the size of one buffer as well, or the 400 (Bad Request) error is returned to the client. Buffers are allocated only on demand. By default, the buffer size is equal to 8K bytes. If after the end of request processing a connection is transitioned into the keep-alive state, these buffers are released.

so you need to change the size parameter at the end of that line to something bigger for your needs.

os.system("stty -icanon -echo")
while True:
    raw_c = sys.stdin.buffer.peek()
    c = sys.stdin.read(1)
    print(f"Char: {c}")

**A problem occurred evaluating project ':app'.

Could not resolve all files for configuration 'classpath'.**

Solution: Platform->cordova-support-google-services

In this file Replace classpath 'com.android.tools.build:gradle:+' to this classpath 'com.android.tools.build:gradle:3.+'

This what helped me:

1. Delete the project from eclipse (but don't delete from disk)
2. Close eclipse
3. In your user folder there is .m folder. Delete repository folder underneath it (.m/repository).
4. Open eclipse
5. Import project as existing maven project (from disk).

Good luck.

I encountered the same error message but don't have any access to the table like "dba_free_space" because I am not a dba. I use some previous answers to check available space and I still have a lot of space. However, after reducing the full table scan as many as possible. The problem is solved. My guess is that Oracle uses temp table to store the full table scan data. It the data size exceeds the limit, it will show the error. Hope this helps someone with the same issue

You will need to store the image in the database as a BLOB.

you will want to create a column called PHOTO in your table and set it as a mediumblob.

Then you will want to get it from the form like so:

    $data = file_get_contents($_FILES['photo']['tmp_name']);

and then set the column to the value in $data.

Of course, this is bad practice and you would probably want to store the file on the system with a name that corresponds to the users account.

you have the print_r function DOC

I am using a a very simple aproach. After a file has been uploaded, i shortly remove the input control, using *ngIf. That will cause the input field being removed from the dom and re-added, consequencely it is a new control, and therefore it is emply:

showUploader: boolean = true;

async upload($event) {
  await dosomethingwiththefile();
  this.showUploader = false;
  setTimeout(() =>{ this.showUploader = true }, 100);
}

<input type="file" (change)="upload($event)" *ngIf="showUploader">
