In Slurm the number of tasks is essentially the number of parallel programs you can start in your allocation. By default, each task can access one CPU (which can be core or thread, depending on config), which can be modified with --cpus-per-task=#.

This in itself does not tell you anything about the number of nodes you will get. If you just specify --ntasks (or just -n), your job will be spread over many nodes, depending on whats available. You can limit this with --nodes #min-#max/--nodes #exact. Another way to specify the number of tasks is --ntasks-per-node, which does exactly what is says and is best used in conjunction with --nodes. (not with --ntasks, otherwise it's the max number of tasks per node!)

So, if you want three nodes with 72 tasks (each with the one default CPU), try:

You are able to access a runtime pallet's storage once the runtime is built, process done by the macro construct_runtime!{}. As you can read here https://substrate.dev/rustdocs/v3.0.0-monthly-2021-05/frame_support/macro.construct_runtime.html A pallet that doesn't appear in that macro won't be part of your runtime, and so its storage will not be accessible.

As per the Quicksight Pricing Page, if you're creating an embedded dashboard for a Quicksight "Reader", then you're paying $0.30/session per 30-minute logged-in-session for this Reader.

The validity of the session can be set in the SessionLifetimeInMinutes parameter of the GetDashboardEmbedUrl API, and has an upper bound of 600 minutes (10 hours).

As an example, suppose you set SessionLifetimeInMinutes to 600 mins for your Reader user. Also suppose that this user stayed logged in and uses the dashboard for 10 hours continuously, then that would equate to 20 sessions of usage (since the billing is in increments of 30-min chunks). At first glance it would seem that this would cause $0.30/session * 20 session-chunks = $6 to be billed.

However, as per the pricing page, there is an upper bound of $5.00 per month for every Reader. Which means that this Reader can never exceed $5 per month regardless of how many Quicksight sessions (of whatever duration) are created for them. So no matter how many times you call the GetDashboardEmbedUrl API for a given Reader, you're capped to $5/month for this user.

Also of use as to what constitutes a Reader session (from the pricing page):

Right off the bat, I see a few issues that would break the code:

1. You're adding the attendee to the list and then checking if it exists in the list afterwards (which it always will after adding it if checking correctly).
2. if (attendeeList.contains(attendee.PassportNumber)) will never return true because you're checking if the entire List has an object that is equal to the PassportNumber in it (as opposed to the PassportNumber in the object). It should be if(attendee.getPassportNumber().equals(Attendee_passport)).

Not sure how much of a beginner you are but it might also be useful to look into things like naming conventions (in general Java variables should be named with a lowercase first letter and each new word has an uppercase letter), using List as the declared variable type instead of ArrayList, and things like filtering lists using Java Streams to see if something exists already. Java also has Set as an alternative to List for when you only want to store unique values (there's other differences between List and Set so make sure you look into it if you want to use it).

The short answer is - I am not aware of any application that works with integrated .mp4 videos today.

After a few current attempts, I can only confirm the statement already made by Tim Green in 2014:

.. CHM now only permits embedding of SWF video files. All other video file formats must be external to the CHM, otherwise they won't play.

Please note following hints quoted from About using video files

Use online video services in CHM. Help+Manual handles this so that the online site is only accessed when the user actually clicks on the preview image to start the video.

Local video formats will always cause problems in CHM files for at least some of your users and should be avoided.

Since the termination of Flash support, Microsoft CHM files no longer support embedding for any video formats. MP4 video files can be embedded in Windows eWriter eBooks. All other video files must be distributed with your help as separate files.

• Running Applets/Media Player etc in a HH Window

For special cases I remember some old stuff to leave the video files outside the help file and use scripting to reference them. Including large video files in your help project could result in an enormous compiled help file. There may also be times when you need to update these files.

• when ever you see yourself using hasOne relationship think of creating a field !
• if you have a like and a dislike and no relationship those are 3 possibilities of interaction of the user on the post so it would be efficient if you have exactly a combination of 3 possibilities of data in your db .

record exists => there an interaction : 0 for dislike and 1 for like .
record does not exist => there is no interaction .

in your code you used like and dislike fields which means you have 4 possibilités which doesnt make any sense since we only need 2 ( and the does not exits ) . i would recommand to change your migration for less queries and tests , remove the like model and use model method (likes , liked ..)

Add protected $table in your Model, change your model into

After raising the question as an issue on github, it was pointed out to me that it had already been answered here.

Here's what I put in keybindings.json do make it work:

@Joab.Ai, thank you for posting this issue! We've identified this to be specific to the latest version of qsharp (0.16.2104.138035). While we are looking into a fix, a workaround will be to downgrade your qsharp package version:

Edit: we have fixed this issue in our latest release! Update to the latest version with this command:
