jsonData = """{"from": {"id": "8", "name": "Mary Pinter"}, "message": "How ARE you?", "comments": {"count": 0}, "updated_time": "2012-05-01", "created_time": "2012-05-01", "to": {"data": [{"id": "1543", "name": "Honey Pinter"}, {"name": "Joe Schmoe"}]}, "type": "status", "id": "id_7"}"""

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        print("to_id:", dest.get('id', 'null'))

Try it:

>>> getTargetIds(jsonData)
to_id: 1543
to_id: null

Or, if you just want to skip over values missing ids instead of printing 'null':

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        if 'id' in to_id:
            print("to_id:", dest['id'])

So:

>>> getTargetIds(jsonData)
to_id: 1543

Of course in real life, you probably don't want to print each id, but to store them and do something with them, but that's another issue.

I solved the problem in my case by deleting file

C:\Users\username.AndroidStudioX\studio64.exe.vmoptions

( x denotes the version of your android studio so it can be different ) , because I created it before to customize VM options. It's that simple

You can't run two SQL statements into one like you are doing.

You can't "execute" a select query.

db is an object and you haven't set it to anything: (e.g. set db = currentdb)

In VBA integer types can hold up to max of 32767 - I would be tempted to use Long.

You might want to be a bit more specific about the date you are inserting:

INSERT INTO Test (Start_Date) VALUES ('#" & format(InDate, "mm/dd/yyyy") & "#' );"

Sure it's possible... use Export Wizard in source option use SQL SERVER NATIVE CLIENT 11, later your source server ex.192.168.100.65\SQLEXPRESS next step select your new destination server ex.192.168.100.65\SQL2014

Just be sure to be using correct instance and connect each other

Just pay attention in Stored procs must be recompiled

Ok folks, I ran into this problem this weekend when my OpenStack environment crashed. Another post about that coming soon on how to recover.

I found a solution that worked for me with a SQL Server instance running under the Ver 15.1 Distrib 10.1.21-MariaDB with Fedora 25 Server as the host. Do not listen to all the other posts that say your database is corrupted if you completely copied your old mariadb-server's /var/lib/mysql directory and the database you are copying is not already corrupted. This process is based on a system where the OS became corrupted but its files were still accessible.

Here are the steps I followed.

1. Make sure that you have completely uninstalled any current versions of SQL only on the NEW server. Also, make sure ALL mysql-server or mariadb-server processes on the NEW AND OLD servers have been halted by running:

   service mysqld stop or service mariadb stop.

2. On the NEW SQL server go into the /var/lib/mysql directory and ensure that there are no files at all in this directory. If there are files in this directory then your process for removing the database server from the new machine did not work and is possibly corrupted. Make sure it completely uninstalled from the new machine.

3. On the OLD SQL server:

   mkdir /OLDMYSQL-DIR cd /OLDMYSQL-DIR tar cvf mysql-olddirectory.tar /var/lib/mysql gzip mysql-olddirectory.tar

4. Make sure you have sshd running on both the OLD and NEW servers. Make sure there is network connectivity between the two servers.

5. On the NEW SQL server:

   mkdir /NEWMYSQL-DIR

6. On the OLD SQL server:

   cd /OLDMYSQL-DIR scp mysql-olddirectory.tar.gz @:/NEWMYSQL-DIR

7. On the NEW SQL server:

   cd /NEWMYSQL-DIR gunzip mysql-olddirectory.tar.gz OR tar zxvf mysql-olddirectory.tar.gz (if tar zxvf doesn't work) tar xvf mysql-olddirectory.tar.gz

8. You should now have a "mysql" directory file sitting in the NEWMYSQL-DIR. Resist the urge to run a "cp" command alone with no switches. It will not work. Run the following "cp" command and ensure you use the same switches I did.

   cd mysql/ cp -rfp * /var/lib/mysql/

9. Now you should have a copy of all of your old SQL server files on the NEW server with permissions in tact. On the NEW SQL server:

   cd /var/lib/mysql/

VERY IMPORTANT STEP. DO NOT SKIP

> rm -rfp ib_logfile*

10. Now install mariadb-server or mysql-server on the NEW SQL server. If you already have it installed and/or running then you have not followed the directions and these steps will fail.

FOR MARIADB-SERVER and DNF:

> dnf install mariadb-server
> service mariadb restart

FOR MYSQL-SERVER and YUM:

> yum install mysql-server
> service mysqld restart

We can include and exclude data types as per the requirement as below:

train.select_dtypes(include=None, exclude=None)
train.select_dtypes(include='number') #will include all the numeric types

Referred from Jupyter Notebook.

To select all numeric types, use np.number or 'number'

• To select strings you must use the object dtype but note that this will return all object dtype columns

• See the NumPy dtype hierarchy <http://docs.scipy.org/doc/numpy/reference/arrays.scalars.html>__

• To select datetimes, use np.datetime64, 'datetime' or 'datetime64'

• To select timedeltas, use np.timedelta64, 'timedelta' or 'timedelta64'

• To select Pandas categorical dtypes, use 'category'

• To select Pandas datetimetz dtypes, use 'datetimetz' (new in 0.20.0) or ``'datetime64[ns, tz]'

The element hasn't been appended yet, therefore it is equal to null. The Id will never = 0. When you call getElementById(id), it is null since it is not a part of the dom yet unless your static id is already on the DOM. Do a call through the console to see what it returns.

The following works without flattening the folder structure:

gulp.src(['input/folder/**/*']).pipe(gulp.dest('output/folder'));

The '**/*' is the important part. That expression is a glob which is a powerful file selection tool. For example, for copying only .js files use: 'input/folder/**/*.js'

You don't need to use display:inline to achieve this:

.inline { 
    border: 1px solid red;
    margin:10px;
    float:left;/*Add float left*/
    margin :10px;
}

You can use float-left.

Using float:left is best way to place multiple div elements in one line. Why? Because inline-block does have some problem when is viewed in IE older versions.

The following does not return a response:

You must return anything like return afunction() or return 'a string'.

This can solve the issue

1. Open "Start" (Windows Button)
2. Search for "Turn Windows features On or Off"
3. Check "Telnet client" and check "Telnet server".

Abstraction: Hiding the data. Encapsulation: Binding the data.

try this

html

<div ng-controller="MyCtrl">
  Hello, {{newDate | date:'MM/dd/yyyy'}}!
</div>

JS

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {
    var collectionDate = '2002-04-26T09:00:00'; 

    $scope.newDate =new Date(collectionDate);
}

Demo

It has 2 possible solutions:

1) You can set it in the view by javascript... (not recomended)

<input class="form-control"
       type="text"
       id="tbFormControll"
       th:field="*{clientName}"/>

<script type="text/javascript">
        document.getElementById("tbFormControll").value = "default";
</script>

2) Or the better solution is to set the value in the model, that you attach to the view in GET operation by a controller. You can also change the value in the controller, just make a Java object from $client.name and call setClientName.

public class FormControllModel {
    ...
    private String clientName = "default";
    public String getClientName () {
        return clientName;
    }
    public void setClientName (String value) {
        clientName = value;
    }
    ...
}

I hope it helps.

I Have faced the same issue.After a lot of struggle I found that the real issue is with the com.amazonaws dependencies.After adding dependencies this error got disappeared.

As Darren commented, Apache don't understand php.ini relative paths in Windows.

To fix it, change the relative paths in your php.ini to absolute paths.

extension_dir="C:\full\path\to\php\ext\dir"

Use attributed string:

// Define attributes
let labelFont = UIFont(name: "HelveticaNeue-Bold", size: 18)
let attributes :Dictionary = [NSFontAttributeName : labelFont]

// Create attributed string
var attrString = NSAttributedString(string: "Foo", attributes:attributes)
label.attributedText = attrString

You need to define attributes.

Using attributed string you can mix colors, sizes, fonts etc within one text

In golang's wiki it show some tricks for slice, including delete an element from slice.

Link: enter link description here

For example a is the slice which you want to delete the number i element.

a = append(a[:i], a[i+1:]...)

OR

a = a[:i+copy(a[i:], a[i+1:])]

AngularJS Developer Guide - CSS classes used by AngularJS

• @property {boolean} $untouched True if control has not lost focus yet.
• @property {boolean} $touched True if control has lost focus.
• @property {boolean} $pristine True if user has not interacted with the control yet.
• @property {boolean} $dirty True if user has already interacted with the control.

Let me summarize all the answers and add some more.

• To write to a file from within your script, user file I/O tools that are provided by Python (this is the f=open('file.txt', 'w') stuff.

• If don't want to modify your program, you can use stream redirection (both on windows and on Unix-like systems). This is the python myscript > output.txt stuff.

• If you want to see the output both on your screen and in a log file, and if you are on Unix, and you don't want to modify your program, you may use the tee command (windows version also exists, but I have never used it)

• Even better way to send the desired output to screen, file, e-mail, twitter, whatever is to use the logging module. The learning curve here is the steepest among all the options, but in the long run it will pay for itself.

If anybody is just like me willing to use jQuery, but still found himself looking to this question then this may help you guys:

The path /usr/local/bin/composer is not in your PATH, executables in that folder won't be found.

Delete the folder /usr/local/bin/composer, then run

$ mv composer.phar /usr/local/bin/composer

This moves composer.phar into /usr/local/bin/ and renames it into composer (which is still an executable, not a folder).

Then just use it like:

$ composer ...

I had the exact same error but with slightly different format and root-cause, and since this is the first Q&A that pops up when you search for "time data does not match format", I thought I'd leave the mistake I made for future viewers:

My initial code:

start = datetime.strptime('05-SEP-19 00.00.00.000 AM', '%d-%b-%y %I.%M.%S.%f %p')

Where I used %I to parse the hours and %p to parse 'AM/PM'.

The error:

ValueError: time data '05-SEP-19 00.00.00.000000 AM' does not match format '%d-%b-%y %I.%M.%S.%f %p'

I was going through the datetime docs and finally realized in 12-hour format %I, there is no 00... once I changed 00.00.00 to 12.00.00, the problem was resolved.

So it's either 01-12 using %I with %p, or 00-23 using %H.

If using the following HTML:

<button id="submit-button"></button>

Style can be applied through JS using the style object available on an HTMLElement.

To set height and width to 200px of the above example button, this would be the JS:

var myButton = document.getElementById('submit-button');
myButton.style.height = '200px';
myButton.style.width= '200px';

I believe with this method, you are not directly writing CSS (inline or external), but using JavaScript to programmatically alter CSS Declarations.

Open the hosts file located at : **C:\windows\system32\drivers\etc**.

Hosts file is for what?

Add the following at end of this file :

YourServerIP YourDNS

Example:

198.168.1.1 maps.google.com

This new issue is caused by the latest version of Android.

Go to your project root folder, open gradle.properties, and add the following options:

org.gradle.daemon=true

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

org.gradle.parallel=true

org.gradle.configureondemand=true

Then add these changes in your build.gradle file:

dexOptions {
        incremental = true
        preDexLibraries = false
        javaMaxHeapSize "4g" // 2g should be also OK
}

This is an easy way to get a successful response from the server like PHP echo otherwise an error message.

BufferedReader br = null;
if (conn.getResponseCode() == 200) {
    br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String strCurrentLine;
        while ((strCurrentLine = br.readLine()) != null) {
               System.out.println(strCurrentLine);
        }
} else {
    br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
    String strCurrentLine;
        while ((strCurrentLine = br.readLine()) != null) {
               System.out.println(strCurrentLine);
        }
}

After messing around with this garbage. I've found a way to download my sweet file by using chrome - developer tools.

1. At your google docs tab, Ctr+Shift+J (Setting --> Developer tools)
2. Switch to Network tabs
3. At your docs file, click "Download" --> Download as CSV, xlsx,....

4. It will show you the request in the "Network" console

5. Right click -> Copy -> Copy as Curl

6. Your Curl command will be like this, and add -o to create a exported file. curl 'https://docs.google.com/spreadsheets/d/1Cjsryejgn29BDiInOrGZWvg/export?format=xlsx&id=1Cjsryejgn29BDiInOrGZWvg' -H 'authority: docs.google.com' -H 'upgrade-insecure-requests: 1' -H 'user-agent: Mozilla/5.0 (X..... -o server.xlsx

Solved!

You need to add the path to environment variables (Windows) like such:

Variable Name: GRADLE_HOME
Variable Value: path

Please check below image:

Yet another answer...but I usually find myself in a case, when I need to load data simultaneously and put it into variables, like:

var cats = new List<Cat>();
var dog = new Dog();

var loadDataTasks = new Task[]
{
    Task.Run(async () => cats = await LoadCatsAsync()),
    Task.Run(async () => dog = await LoadDogAsync())
};

try
{
    await Task.WhenAll(loadDataTasks);
}
catch (Exception ex)
{
    // handle exception
}

The previous answers assume that you indeed calculated TP/Sens yourself. It's a bad idea to do this manually, it's easy to make mistakes with the calculations, rather use a library function for all of this.

the plot_roc function in scikit_lean does exactly what you need: http://scikit-learn.org/stable/auto_examples/model_selection/plot_roc.html

The essential part of the code is:

  for i in range(n_classes):
      fpr[i], tpr[i], _ = roc_curve(y_test[:, i], y_score[:, i])
      roc_auc[i] = auc(fpr[i], tpr[i])

This works in Swift 3.0:

btn.titleLabel?.font = UIFont(name:"Times New Roman", size: 20) 

if you want to run app in debug mode

1) Look at Left Side bottom, above Favorites there is Build Variants

2) Click on Build Variants. Click on release and choose debug

it works perfect !!!

you can use an object

var days = {
   'Mon': 'Monday',
   'etc..': 'etc..',
   'Fri': 'Friday'
}

var date = new Date().toString().split(' ')[0]; //get day abreviation first
console.log(days[date]);

I fixed it adding these lines in the build.grandle (App Module)

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar']) //it was there
   compile "com.android.support:support-v4:21.0.+" //Added
   compile "com.android.support:appcompat-v7:21.0.+" //Added
}

If you are looking for answer in string values , try this

var check = moment('date/utc format');
day = check.format('dddd') // => ('Monday' , 'Tuesday' ----)
month = check.format('MMMM') // => ('January','February.....)
year = check.format('YYYY') // => ('2012','2013' ...)  

In Laravel 5.1 and later you can use

request()->getHost();

or

request()->getHttpHost();

(the second one will add port if it's not standard one)

Just to add this in, I ran into this same issue, but the supplied answers did not work. I fixed it by taking the exception's suggestion and adding to the application.properties file...

spring.jackson.serialization.fail-on-empty-beans=false

I'm using Spring Boot v1.3 with Hibernate 4.3

It now serializes the entire object and nested objects.

EDIT: 2018

Since this still gets comments I'll clarify here. This absolutely only hides the error. The performance implications are there. At the time, I needed something to deliver and work on it later (which I did via not using spring anymore). So yes, listen to someone else if you really want to solve the issue. If you just want it gone for now go ahead and use this answer. It's a terrible idea, but heck, might work for you. For the record, never had a crash or issue again after this. But it is probably the source of what ended up being a SQL performance nightmare.

There should be a 'Run Script' into 'Build Phases' with this: '/usr/local/bin/carthage copy-frameworks'

On the 'Input Files' of that 'Run Script', you should add the path to your libraries. Like this:

  rgrp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {
            switch(i) {

                    num=1;
                    Toast.makeText(getApplicationContext()," Car",Toast.LENGTH_LONG).show();
                    break;
                case R.id.type_bike:
                    num=2;
                    Toast.makeText(getApplicationContext()," Bike",Toast.LENGTH_LONG).show();

            }
        }
    });

Only providing .ttf file for webfont won't be good enough for cross-browser support. The best possible combination at present is using the combination as :

@font-face {
  font-family: 'MyWebFont';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff') format('woff'), /* Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

This code assumes you have .eot , .woff , .ttf and svg format for you webfont. To automate all this process , you can use : Transfonter.org.

Also , modern browsers are shifting towards .woff font , so you can probably do this too : :

@font-face {
  font-family: 'MyWebFont';
  src: url('myfont.woff') format('woff'), /* Chrome 6+, Firefox 3.6+, IE 9+, Safari 5.1+ */
   url('myfont.ttf') format('truetype'); /* Chrome 4+, Firefox 3.5, Opera 10+, Safari 3—5 */
}

Following Linear / Grid LayoutManager methods can be used to check which items are visible

int findFirstVisibleItemPosition();
int findLastVisibleItemPosition();
int findFirstCompletelyVisibleItemPosition();
int findLastCompletelyVisibleItemPosition();

and if you want to track is item visible on screen for some threshold then you can refer to the following blog.

I experienced this error when trying to embed an iframe and then opening the site with Brave. The error went away when I changed to "Shields Down" for the site in question. Obviously, this is not a full solution, since anyone else visiting the site with Brave will run into the same issue. To actually resolve it I would need to do one of the other things listed on this page. But at least I now know where the problem lies.

Instead of if, ternary operator might come handy when you want to get a value based on whether something is nil:

func f(x: String?) -> String {
    return x == nil ? "empty" : "non-empty"
}

It's better, if you use two div containers in HTML .

As Shown Below:

HTML:

<div id="container1">
    <div id="container2">
        // Content here
    </div>
</div>

CSS:

 #container1{
    height: 100%;
    width: 100%;
    overflow: hidden;
}

 #container2{
    height: 100%;
    width: 100%;
    overflow: auto;
    padding-right: 20px;
}

Manually creating a folder named 'npm' in the displayed path fixed the problem.

If you need the path and thedomain for each cookie, which get_dict() is not exposes, you can parse the cookies manually, for instance:

[
    {'name': c.name, 'value': c.value, 'domain': c.domain, 'path': c.path}
    for c in session.cookies
]

I realize that this is an old thread, but for Future-Me, and posterity, I figured I should add my two-cents around the "running npm as sudo" discussion. Disclaimer: I do not use Windows. These steps have only been proven on non-windows machines, both virtual and physical.

You can avoid the need to use sudo by changing the permission to npm's default directory.

How to: change permissions in order to run npm without sudo

Step 1: Find out where npm's default directory is.

• To do this, open your terminal and run:
  npm config get prefix

Step 2: Proceed, based on the output of that command:

• Scenario One: npm's default directory is /usr/local
  For most users, your output will show that npm's default directory is /usr/local, in which case you can skip to step 4 to update the permissions for the directory.
• Scenario Two: npm's default directory is /usr or /Users/YOURUSERNAME/node_modules or /Something/Else/FishyLooking
  If you find that npm's default directory is not /usr/local, but is instead something you can't explain or looks fishy, you should go to step 3 to change the default directory for npm, or you risk messing up your permissions on a much larger scale.

Step 3: Change npm's default directory:

• There are a couple of ways to go about this, including creating a directory specifically for global installations and then adding that directory to your $PATH, but since /usr/local is probably already in your path, I think it's simpler to just change npm's default directory to that. Like so: npm config set prefix /usr/local
  • For more info on the other approaches I mentioned, see the npm docs here.

Step 4: Update the permissions on npm's default directory:

• Once you've verified that npm's default directory is in a sensible location, you can update the permissions on it using the command:
  sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

Now you should be able to run npm <whatever> without sudo. Note: You may need to restart your terminal in order for these changes to take effect.

You need to add "hold-on-click" to "dropdown-menu" class

Have you tried using the ConflictResolution:=xlLocalSessionChanges parameter in the SaveAs method?

As so:

Public Sub example()
Application.DisplayAlerts = False
Application.EnableEvents = False

For Each element In sArray
    XLSMToXLSX(element)
Next element

Application.DisplayAlerts = False
Application.EnableEvents = False
End Sub

Sub XLSMToXLSX(ByVal file As String)
    Do While WorkFile <> ""
        If Right(WorkFile, 4) <> "xlsx" Then
            Workbooks.Open Filename:=myPath & WorkFile

            Application.DisplayAlerts = False
            Application.EnableEvents = False

            ActiveWorkbook.SaveAs Filename:= _
            modifiedFileName, FileFormat:= _
            xlOpenXMLWorkbook, CreateBackup:=False, _
            ConflictResolution:=xlLocalSessionChanges

            Application.DisplayAlerts = True
            Application.EnableEvents = True

            ActiveWorkbook.Close
        End If
        WorkFile = Dir()
    Loop
End Sub

In my case (Linux) is alt+shift up/down

 { "keys": ["alt+shift+up"], "command": "select_lines", "args": {"forward": false} },
 { "keys": ["alt+shift+down"], "command": "select_lines", "args": {"forward": true} },    

For those wondering, @edward-coast

If you want to set the keep alive for the server, add this to /etc/ssh/sshd_config:

ClientAliveInterval 60
ClientAliveCountMax 2

ClientAliveInterval: Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client.

ClientAliveCountMax: Sets the number of client alive messages (see below) which may be sent without sshd(8) receiving any messages back from the client. If this threshold is reached while client alive messages are being sent, sshd will disconnect the client, terminating the session.

I think you mean to use map instead of filter:

>>> from string import upper
>>> mylis=['this is test', 'another test']
>>> map(upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

Even simpler, you could use str.upper instead of importing from string (thanks to @alecxe):

>>> map(str.upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

In Python 2.x, map constructs a new list by applying a given function to every element in a list. filter constructs a new list by restricting to elements that evaluate to True with a given function.

In Python 3.x, map and filter construct iterators instead of lists, so if you are using Python 3.x and require a list the list comprehension approach would be better suited.

In addition to great extension written here if you are lazy to find and replace old NSLocalizedString you can open find & replace in Xcode and in the find section you can write NSLocalizedString\(\(".*"\), comment: ""\) then in the replace section you need to write $1.localized to change all NSLocalizedString with "blabla".localized in your project.

I had to run my commands in the one and same terminal, not seperately.

nohup sudo Xvfb :10 -ac
export DISPLAY=:10
java -jar vendor/se/selenium-server-standalone/bin/selenium-server-standalone.jar -Dwebdriver.chrome.bin="/usr/bin/google-chrome" -Dwebdriver.chrome.driver="vendor/bin/chromedriver"

TL;DR: Use __builtin intrinsics instead; they might happen to help.

I was able to make gcc 4.8.4 (and even 4.7.3 on gcc.godbolt.org) generate optimal code for this by using __builtin_popcountll which uses the same assembly instruction, but gets lucky and happens to make code that doesn't have an unexpectedly long loop-carried dependency because of the false dependency bug.

I am not 100% sure of my benchmarking code, but objdump output seems to share my views. I use some other tricks (++i vs i++) to make the compiler unroll loop for me without any movl instruction (strange behaviour, I must say).

Thanks @Arnaud & @Conny for highlighting this answer. This really helped me. I would like to add one more thing here is, adding this line <meta http-equiv="x-ua-compatible" content="IE=edge"> just after the title in tag prior to all meta tags is must for to work as it overrides the compatibility mode of IE.

You get that error because you don't have the public key of the person who signed the message.

gpg should have given you a message containing the ID of the key that was used to sign it. Obtain the public key from the person who encrypted the file and import it into your keyring (gpg2 --import key.asc); you should be able to verify the signature after that.

If the sender submitted its public key to a keyserver (for instance, https://pgp.mit.edu/), then you may be able to import the key directly from the keyserver:

gpg2 --keyserver https://pgp.mit.edu/ --search-keys <sender_name_or_address>

Your C# action "Save" doesn't execute because your AJAX url is pointing to "/Home/SaveDetailedInfo" and not "/Home/Save".

To call another action from within an action you can maybe try this solution: link

Here's another better solution : link

[HttpPost]
public ActionResult SaveDetailedInfo(Option[] Options)
{
    return Json(new { status = "Success", message = "Success" });
}

[HttpPost]
public ActionResult Save()
{ 
    return RedirectToAction("SaveDetailedInfo", Options);
}

AJAX:

Initial ajax call url: "/Home/Save"
on success callback: 
   make new ajax url: "/Home/SaveDetailedInfo"

There is an important bit that is not mentioned in the article to which you linked and that is flex-basis. By default flex-basis is auto.

From the spec:

If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)

Each flex item has a flex-basis which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow) among the items. With auto, that basis is the contents size (or defined size with width, etc.). As a result, items with bigger text within are being given more space overall in your example.

If you want your elements to be completely even, you can set flex-basis: 0. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow.

li {
    flex-grow: 1;
    flex-basis: 0;
    /* ... */
}

This diagram from the spec does a pretty good job of illustrating the point.

And here is a working example with your fiddle.

You can set triangle with position see this code for reference

.top-left-corner {
    width: 0px;
    height: 0px;
    border-top: 0px solid transparent;
    border-bottom: 55px solid transparent;
    border-left: 55px solid #289006;
    position: absolute;
    left: 0px;
    top: 0px;
}

Great work Andreas. I created a bean version so the SessionFactory could be autowired.

import javax.persistence.EntityManagerFactory;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;

....

@Autowired
private EntityManagerFactory entityManagerFactory;

@Bean
public SessionFactory getSessionFactory() {
    if (entityManagerFactory.unwrap(SessionFactory.class) == null) {
        throw new NullPointerException("factory is not a hibernate factory");
    }
    return entityManagerFactory.unwrap(SessionFactory.class);
}

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

If you have a list view you can do this:

1. Define a select list:

   @{
      var Acciones = new SelectList(new[]
      {
     new SelectListItem { Text = "Modificar", Value = 
      Url.Action("Edit", "Countries")},
     new SelectListItem { Text = "Detallar", Value = 
     Url.Action("Details", "Countries") },
     new SelectListItem { Text = "Eliminar", Value = 
     Url.Action("Delete", "Countries") },
    }, "Value", "Text");
   }
   

2. Use the defined SelectList, creating a diferent id for each record (remember that id of each element must be unique in a view), and finally call a javascript function for onchange event (include parameters in example url and record key):

   @Html.DropDownList("ddAcciones", Acciones, "Acciones", new { id = 
   item.CountryID, @onchange = "RealizarAccion(this.value ,id)" })
   

3. onchange function can be something as:

   @section Scripts {
   <script src="~/Scripts/jquery-1.10.2.min.js"></script>
   <script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
   
   <script type="text/javascript">
   
   function RealizarAccion(accion, country)
   {
   
       var url = accion + '/' + country;
       if (url != null && url != '') {
           window.location.href = url ;
       }
   }
   </script>
   
   @Scripts.Render("~/bundles/jqueryval")
   }
   

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Rows.Count

or

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Cells.Count

or

k = sh.Range("A2", sh.Range("A1").End(xlDown)).Count

I had a similar requirement, but I wanted the n'th item in a particular group. This is how I solved it.

groups = data.groupby(['group_key'])
selection = groups['index_col'].apply(lambda x: x % 3 == 0)
subset = data[selection]

The answer from the Abiraman was absolutely correct. However, for newbies to git, they might forget to pull the repository. Whenever you want to do a merge from branchB into branchA. First checkout and take pull from branchB (Make sure that, your branch is updated with remote branch)

git checkout branchB

git pull

Now you local branchB is updated with remote branchB Now you can checkout to branchA

git checkout branchA

Now you are in branchA, then you can merge with branchB using following command

git merge branchB

lst = [['a','b','c'], [1,2,3], ['x','y','z']]
outputlist = []
for values in lst:
    outputlist.append(values[0])

print(outputlist) 

Output: ['a', 1, 'x']

Pandas uses numpy's NaN value. Use numpy.isnan to obtain a Boolean vector from a pandas series.

you just need to put this

($('#{{ form.email.id_for_label }}').attr("placeholder","Work email address"));

($('#{{ form.password1.id_for_label }}').attr("placeholder","Password"));

In the App class you can set the MainPage to a Navigation Page and set the root page to your ContentPage:

public App ()
{
    // The root page of your application
    MainPage = new NavigationPage( new FirstContentPage() );
}

Then in your first ContentPage call:

Navigation.PushAsync (new SecondContentPage ());

@Chris Haas has explained very well how to use itextSharp to convert HTML to PDF, very helpful

of course include iTextSharp Refrences to cs file

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;
using iTextSharp.tool.xml;

Hope this helps!
Thank you

Just download and install LocalDB 64BIT\SqlLocalDB.msi can also solve this problem. You don't really need to uninstall and reinstall SQL Server 2014 Express with Advanced Services.

I used this:

HTMLDatetoIsoDate(htmlDate){
  let year = Number(htmlDate.toString().substring(0, 4))
  let month = Number(htmlDate.toString().substring(5, 7))
  let day = Number(htmlDate.toString().substring(8, 10))
  return new Date(year, month - 1, day)
}

isoDateToHtmlDate(isoDate){
  let date = new Date(isoDate);
  let dtString = ''
  let monthString = ''
  if (date.getDate() < 10) {
    dtString = '0' + date.getDate();
  } else {
    dtString = String(date.getDate())
  }
  if (date.getMonth()+1 < 10) {
    monthString = '0' + Number(date.getMonth()+1);
  } else {
    monthString = String(date.getMonth()+1);
  }
  return date.getFullYear()+'-' + monthString + '-'+dtString
}

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

This example will clear every aspect!

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

Iterate over an objects attributes in python:

class C:
    a = 5
    b = [1,2,3]
    def foobar():
        b = "hi"    

for attr, value in C.__dict__.iteritems():
    print "Attribute: " + str(attr or "")
    print "Value: " + str(value or "")

Prints:

python test.py
Attribute: a
Value: 5
Attribute: foobar
Value: <function foobar at 0x7fe74f8bfc08>
Attribute: __module__
Value: __main__
Attribute: b
Value: [1, 2, 3]
Attribute: __doc__
Value:

var __startTime = moment("2016-06-06T09:00").format();
var __endTime = moment("2016-06-06T21:00").format();

var __duration = moment.duration(moment(__endTime).diff(__startTime));
var __hours = __duration.asHours();
console.log(__hours);

Aha!

This can be done with the following PHP function:

error_log('Some message here.');

Found the answer here: Print something in PHP built-in web server

The flatMap method on Stream can certainly flatten those lists for you, but it must create Stream objects for element, then a Stream for the result.

You don't need all those Stream objects. Here is the simple, concise code to perform the task.

// listOfLists is a List<List<Object>>.
List<Object> result = new ArrayList<>();
listOfLists.forEach(result::addAll);

Because a List is Iterable, this code calls the forEach method (Java 8 feature), which is inherited from Iterable.

Performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration, if that order is specified.

And a List's Iterator returns items in sequential order.

For the Consumer, this code passes in a method reference (Java 8 feature) to the pre-Java 8 method List.addAll to add the inner list elements sequentially.

Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator (optional operation).

I used below ms sql script pattern several times successfully which uses Try-Catch,Commit Transaction- Rollback Transaction,Error Tracking.

Your TRY block will be as follows

 BEGIN TRY
 BEGIN TRANSACTION T
 ----
 //your script block
 ----
 COMMIT TRANSACTION T 
 END TRY

Your CATCH block will be as follows

BEGIN CATCH
DECLARE @ErrMsg NVarChar(4000), 
        @ErrNum Int, 
        @ErrSeverity Int, 
        @ErrState Int, 
        @ErrLine Int, 
        @ErrProc NVarChar(200)
 SELECT @ErrNum = Error_Number(), 
       @ErrSeverity = Error_Severity(), 
       @ErrState = Error_State(), 
       @ErrLine = Error_Line(), 
       @ErrProc = IsNull(Error_Procedure(), '-')
 SET @ErrMsg = N'ErrLine: ' + rtrim(@ErrLine) + ', proc: ' + RTRIM(@ErrProc) + ', 
       Message: '+ Error_Message()

Your ROLLBACK script will be part of CATCH block as follows

IF (@@TRANCOUNT) > 0 
BEGIN
PRINT 'ROLLBACK: ' + SUBSTRING(@ErrMsg,1,4000)
ROLLBACK TRANSACTION T
END
ELSE
BEGIN
PRINT SUBSTRING(@ErrMsg,1,4000);   
END

END CATCH

Above different script blocks you need to use as one block. If any error happens in the TRY block it will go the the CATCH block. There it is setting various details about the error number,error severity,error line ..etc. At last all these details will get append to @ErrMsg parameter. Then it will check for the count of transaction (@@TRANCOUNT >0) , ie if anything is there in the transaction for rollback. If it is there then show the error message and ROLLBACK TRANSACTION. Otherwise simply print the error message.

We have kept our COMMIT TRANSACTION T script towards the last line of TRY block in order to make sure that it should commit the transaction(final change in the database) only after all the code in the TRY block has run successfully.

I ran into this problem when SQL Server 2014 standard was installed on a server where SQL Server Express was also installed. I had opened SSMS from a desktop shortcut, not realizing right away that it was SSMS for SQL Server Express, not for 2014. SSMS for Express returned the error, but SQL Server 2014 did not.

With Swift 5, according to your needs, you may choose one of the six following ways to concatenate/merge two arrays.

#1. Merge two arrays into a new array with Array's +(_:_:) generic operator

Array has a +(_:_:) generic operator. +(_:_:) has the following declaration:

Creates a new collection by concatenating the elements of a collection and a sequence.

static func + <Other>(lhs: Array<Element>, rhs: Other) -> Array<Element> where Other : Sequence, Self.Element == Other.Element

The following Playground sample code shows how to merge two arrays of type [Int] into a new array using +(_:_:) generic operator:

let array1 = [1, 2, 3]
let array2 = [4, 5, 6]

let flattenArray = array1 + array2
print(flattenArray) // prints [1, 2, 3, 4, 5, 6]

#2. Append the elements of an array into an existing array with Array's +=(_:_:) generic operator

Array has a +=(_:_:) generic operator. +=(_:_:) has the following declaration:

Appends the elements of a sequence to a range-replaceable collection.

static func += <Other>(lhs: inout Array<Element>, rhs: Other) where Other : Sequence, Self.Element == Other.Element

The following Playground sample code shows how to append the elements of an array of type [Int] into an existing array using +=(_:_:) generic operator:

var array1 = [1, 2, 3]
let array2 = [4, 5, 6]

array1 += array2
print(array1) // prints [1, 2, 3, 4, 5, 6]

#3. Append an array to another array with Array's append(contentsOf:) method

Swift Array has an append(contentsOf:) method. append(contentsOf:) has the following declaration:

Adds the elements of a sequence or collection to the end of this collection.

mutating func append<S>(contentsOf newElements: S) where S : Sequence, Self.Element == S.Element

The following Playground sample code shows how to append an array to another array of type [Int] using append(contentsOf:) method:

var array1 = [1, 2, 3]
let array2 = [4, 5, 6]

array1.append(contentsOf: array2)
print(array1) // prints [1, 2, 3, 4, 5, 6]

#4. Merge two arrays into a new array with Sequence's flatMap(_:) method

Swift provides a flatMap(_:) method for all types that conform to Sequence protocol (including Array). flatMap(_:) has the following declaration:

Returns an array containing the concatenated results of calling the given transformation with each element of this sequence.

func flatMap<SegmentOfResult>(_ transform: (Self.Element) throws -> SegmentOfResult) rethrows -> [SegmentOfResult.Element] where SegmentOfResult : Sequence

The following Playground sample code shows how to merge two arrays of type [Int] into a new array using flatMap(_:) method:

let array1 = [1, 2, 3]
let array2 = [4, 5, 6]

let flattenArray = [array1, array2].flatMap({ (element: [Int]) -> [Int] in
    return element
})
print(flattenArray) // prints [1, 2, 3, 4, 5, 6]

#5. Merge two arrays into a new array with Sequence's joined() method and Array's init(_:) initializer

Swift provides a joined() method for all types that conform to Sequence protocol (including Array). joined() has the following declaration:

Returns the elements of this sequence of sequences, concatenated.

func joined() -> FlattenSequence<Self>

Besides, Swift Array has a init(_:) initializer. init(_:) has the following declaration:

Creates an array containing the elements of a sequence.

init<S>(_ s: S) where Element == S.Element, S : Sequence

Therefore, the following Playground sample code shows how to merge two arrays of type [Int] into a new array using joined() method and init(_:) initializer:

let array1 = [1, 2, 3]
let array2 = [4, 5, 6]

let flattenCollection = [array1, array2].joined() // type: FlattenBidirectionalCollection<[Array<Int>]>
let flattenArray = Array(flattenCollection)
print(flattenArray) // prints [1, 2, 3, 4, 5, 6]

#6. Merge two arrays into a new array with Array's reduce(_:_:) method

Swift Array has a reduce(_:_:) method. reduce(_:_:) has the following declaration:

Returns the result of combining the elements of the sequence using the given closure.

func reduce<Result>(_ initialResult: Result, _ nextPartialResult: (Result, Element) throws -> Result) rethrows -> Result

The following Playground code shows how to merge two arrays of type [Int] into a new array using reduce(_:_:) method:

let array1 = [1, 2, 3]
let array2 = [4, 5, 6]

let flattenArray = [array1, array2].reduce([], { (result: [Int], element: [Int]) -> [Int] in
    return result + element
})
print(flattenArray) // prints [1, 2, 3, 4, 5, 6]

Thanks to jaknap32, I wanted to aggregate the results according to Year and Month, so this worked:

df_join['YearMonth'] = df_join['timestamp'].apply(lambda x:x.strftime('%Y%m'))

Output was neat:

0    201108
1    201108
2    201108

I got it

Cells(1, 1).Value = StartDate
Cells(1, 1).NumberFormat = "dd/mm/yyyy"

Basically, I need to set the cell format, instead of setting the date.

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

You can use this

whereDate('date', '=', $date)

If you give whereDate then compare only date from datetime field.

In Java, all strings are immutable(Can't change). When you are trying to modify a String, what you are really doing is creating a new one.

Following ways we can create the string object

1. Using String literal

   String str="java";
   

2. Using new keyword

   String str = new String("java");
   

3. Using character array

   char[] helloArray = { 'h', 'e', 'l', 'l', 'o', '.' };
   
   String helloString = new String(helloArray);   
   

coming to String immutability, simply means unmodifiable or unchangeable

Let's take one example

I'm initializing the value to the String literal s

String s="kumar";

Below I'm going to display the decimal representation of the location address using hashcode()

System.out.println(s.hashCode());

Simply printing the value of a String s

System.out.println("value "+s);

Okay, this time I'm inittializing value "kumar" to s1

String s1="kumar";   // what you think is this line, takes new location in the memory ??? 

Okay let's check by displaying hashcode of the s1 object which we created

System.out.println(s1.hashCode());

okay, let's check below code

String s2=new String("Kumar");
    System.out.println(s2.hashCode());  // why this gives the different address ??

Okay, check this below code at last

String s3=new String("KUMAR");
    System.out.println(s3.hashCode());  // again different address ???

YES, if you see Strings 's' and 's1' having the same hashcode because the value hold by 's' & 's1' are same that is 'kumar'

Let's consider String 's2' and 's3' these two Strings hashcode appears to be different in the sense, they both stored in a different location because you see their values are different.

since s and s1 hashcode is same because those values are same and storing in the same location.

Example 1: Try below code and analyze line by line

public class StringImmutable {
public static void main(String[] args) {

    String s="java";
    System.out.println(s.hashCode());
    String s1="javA";
    System.out.println(s1.hashCode());
    String s2=new String("Java");
    System.out.println(s2.hashCode());
    String s3=new String("JAVA");
    System.out.println(s3.hashCode());
}
}

Example 2: Try below code and analyze line by line

public class StringImmutable {
    public static void main(String[] args) {

        String s="java";
        s.concat(" programming");  // s can not be changed "immutablity"
        System.out.println("value of s "+s);
        System.out.println(" hashcode of s "+s.hashCode());

        String s1="java";
        String s2=s.concat(" programming");   // s1 can not be changed "immutablity" rather creates object s2
        System.out.println("value of s1 "+s1);
        System.out.println(" hashcode of s1 "+s1.hashCode());  

        System.out.println("value of s2 "+s2);
        System.out.println(" hashcode of s2 "+s2.hashCode());

    }
}

Okay, Let's look what is the difference between mutable and immutable.

mutable(it change) vs. immutable (it can't change)

public class StringMutableANDimmutable {
    public static void main(String[] args) {


        // it demonstrates immutable concept
        String s="java";
        s.concat(" programming");  // s can not be changed (immutablity)
        System.out.println("value of s ==  "+s); 
        System.out.println(" hashcode of s == "+s.hashCode()+"\n\n");


        // it demonstrates mutable concept
        StringBuffer s1= new StringBuffer("java");
        s1.append(" programming");  // s can be changed (mutablity)
        System.out.println("value of s1 ==  "+s1); 
        System.out.println(" hashcode of s1 == "+s1.hashCode());


    }
}

Any further questions?? please write on...

The NSString version (as opposed to Swift String) of replacingCharacters(in: NSRange, with: NSString) accepts an NSRange, so one simple solution is to convert String to NSString first. The delegate and replacement method names are slightly different in Swift 3 and 2, so depending on which Swift you're using:

Swift 3.0

func textField(_ textField: UITextField,
               shouldChangeCharactersIn range: NSRange,
               replacementString string: String) -> Bool {

  let nsString = textField.text as NSString?
  let newString = nsString?.replacingCharacters(in: range, with: string)
}

Swift 2.x

func textField(textField: UITextField,
               shouldChangeCharactersInRange range: NSRange,
               replacementString string: String) -> Bool {

    let nsString = textField.text as NSString?
    let newString = nsString?.stringByReplacingCharactersInRange(range, withString: string)
}

The following documentation from the Docker website shows how to implement an SSH service in a docker container. It should be easily adaptable for your service:

• https://docs.docker.com/engine/examples/running_ssh_service/

A variation on this question has also been asked here:

• Start sshd automatically with docker container

Another very similar answer is to use "equals" instead of "contains".

After running into the same issue - here're some of my thoughts:

• due to Chrome removing support for h264, on some machines, mp4 videos encoded with it will either not work (throwing an Parser error when viewing under Firebug/Network tab - consistent with issue submitted here), or crash the browser, depending upon the encoding settings
• it isn't consistent - it entirely depends upon the codecs installed on the computer - while I didn't encounter this issue on my machine, we did have one in the office where the issue occurred (and thus we used this one for testing)
• it might to do with Quicktime / divX settings (the machine in question had an older version of Quicktime than my native one - we didn't want to loose our testing pc though, so we didn't update it).

As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:

for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4) apply following js:

if (window.chrome)
    $("[type=video\\\/mp4]").each(function()
    {
        $(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
    });

Unfortunately it's a bad Chrome hack, but hey, at least it works.

This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec

Also check your version of crome here: html5test

BOOTSTRAP 4

you can use a combination of

• fa-chevron-down, fa-chevron-up

• fa-sort-down, fa-sort-up

<th class="text-center">
    <div class="btn-group" role="group">
        <button type="button" class="btn btn-xs btn-link py-0 pl-0 pr-1">
             Some Text OR icon
        </button>
        <div class="btn-group-vertical">
            <a href="?sort=asc" class="btn btn-xs btn-link p-0">
                <i class="fas fa-sort-up"></i>
            </a>
            <a href="?sort=desc" class="btn btn-xs btn-link p-0">
                <i class="fas fa-sort-down"></i>
            </a>
        </div>
    </div>

For posterity: as of 0.15.0, there is a handy .dt accessor you can use to pull such values from a datetime/period series (in the above case, just sales.timestamp.dt.hour!
