PURE | NAACL'2021 : A Frustratingly Easy Approach for Entity | Natural Language Processing library

See 6.4.14.1. Inferred vs. specified type variables:

Since the 9.0.1 release, GHC permits labelling the user-written type or kind variables as inferred, in contrast to the default of specified. By writing the type variable binder in braces as {tyvar} or {tyvar :: kind}, the new variable will be classified as inferred, not specified.

• .. is a specified type
• {..} is an inferred type

forall a. and forall {a}. are invisible quantifiers that GHC will instantiate automatically by unification.

I tried to answer your question without knowing an example.

You need to extract youtubeId from A tag and then replace A tag into iframe tag.

pseudo code is:

Use pure from Control.Functor.Linear instead, as well as the IO from System.IO.Linear, because contents of Prelude are simply not declared as linear.

Note that this even simpler example does not compile too:

Note: When referring to documentation and source code, I provide links to an unofficial GitHub mirror of R's official Subversion repository. The links are bound to commit 97b6424 in the GitHub repo, which maps to revision 81461 in the Subversion repo (the latest at the time of this edit).

substitute is a "special" whose arguments are not evaluated (doc).

Since you mention executing the same files (with proper performance) from within Git Bash, I'm going to make an assumption here. Correct me if I'm wrong on this, and I'll delete the answer and look for another possibility.

This would be explained (and expected) if your files are stored on /mnt/c (a.k.a. C:, or /C under Git Bash) or any other Windows drive, as they would likely need to be to be accessed by Git Bash.

WSL2 uses the 9P protocol to access Windows drives, and it is currently known to be very slow when compared to:

• Native NTFS (obviously)
• The ext4 filesystem on the virtual disk used by WSL2
• And even the performance of WSL1 with Windows drives

I've seen a git clone of a large repo (the WSL2 Linux kernel Github) take 8 minutes on WSL2 on a Windows drive, but only seconds on the root filesystem.

Two possibilities:

• If possible (and it is for most Node projects), convert your WSL to version 1 with wsl --set-version 1. I always recommend making a backup with wsl --export first.

  And since you are making a backup anyway, you may as well just create a copy of the instance by wsl --importing your backup as --version 1 (as the last argument). WSL1 and WSL2 both have their uses, and you may find it helpful to keep both around.

  See this answer for more details on the exact syntax..

• Or just move the project over to somewhere under the WSL root, such as /home/username/src/.

tic/toc should be fine, but it looks like the timing is being skewed by memory pre-allocation.

I can reproduce similar timings to your MATLAB example, however

• On first run (clear workspace)

  • Loop approach takes 2.08 sec
  • Vectorised approach takes 1.04 sec
  • Vectorisation saves 50% execution time

• On second run (workspace not cleared)

  • Loop approach takes 2.55 sec
  • Vectorised approach takes 0.065 sec
  • Vectorisation "saves" 97.5% execution time

My guess would be that since the loop approach explicitly creates a new matrix via zeros, the memory is reallocated from scratch on every run and you don't see the speed improvement on subsequent runs.

However, when HH remains in memory and the HH=___ line outputs a matrix of the same size, I suspect MATLAB is doing some clever memory allocation to speed up the operation.

We can prove this theory with the following test:

Given x.f(1.01);, the name f is found in the scope of class Sub, then name lookup stops; the scope of Abs won't be examined. Only Sub::f is put in overload set and then overload resolution is performed.

... name lookup examines the scopes as described below, until it finds at least one declaration of any kind, at which time the lookup stops and no further scopes are examined.

You can use using to introduce the names of Abs into Sub, then Abs::f could be found and take part in overload resolution too.

On the documentations is it stated that only AlertDialog supports Composable functions and that is the reason you are unable to see the preview.

You can check more details here.

If a function only depends on other pure functions, then it is also pure. Since getPhoneNumberRules() just returns a fixed array, it's pure, so rules() is also pure.

But messages() calls getPhoneNumberMessage(), which calls the __() function that can return a different localized message if the location state changes, so it's not pure.
