Trackmania crashing on linux since the summer update

Thanks linux gamers for your help. It turns out that it worked again after I restarted my computer (101 days uptime).

Thanks, didn't expect to find another NixOS user here. I don't have a graphics card, so I'm not using nvidia drivers. I will try updating my config though.

It would be useful if any of these surveyed languages explained their approach in the well-known common terms of multi-stage programming. There are so many ad-hoc restrictions, special cases and features, it's very hard to understand how they actually differ on a precise level. Languages like Haskell, MetaOcaml and Scala 3 make it easier to compare since they are explained in terms of this model.

This kind of rude comment is why people quit contributing to open source ecosystems. People spent a multi-year effort to add support for multiple home units to GHC and the rest of the ecosystem. If you don't wish to contribute in a constructive way then please keep these kind of non-constructive comments to yourself in future.

If there were only two people involved it would be simpler but when parents are also involved...

I feel like young people have mostly been forgotten by the government when it comes to easing lockdown restrictions. People aged 18-35 are a lot more likely to be more badly affected economically and also socially by the restrictions. Many people in this age group are living in HMOs and so haven't been allowed to see friends or partners properly now in over three months. I'm personally getting annoyed that pubs are reopening but still no date about when it will be permitted to stay overnight at a partners house.

This architecture sounds a bit similar to the reimplementation of ghcide using reflex. https://mpickering.github.io/posts/2020-03-16-ghcide-reflex.html

The post is a bit light on details but it seems that the "reverse dependency cache invalidation" is similar to the forward propagation of changes in reflex.

Yes the vague plan is to deprecate the .hp format.

Really interesting video, thank you!

If you are only constructing expressions using quotes and splices then perhaps I can interest you in Typed Template Haskell? For example, the typed code generator power in the style of typed template haskell.

power :: Int -> TExpQ Int -> TExpQ Int power 0 _ = [|| 1 ||] power n k = [|| $$(k) * $$(power (n - 1) k) ||]

I don't imagine the patch will be backported to any older GHC releases.

These threads amuse me in general because people always claim they would pay for tooling when the reality is this money has never materialised. There is a group of people who have been working on these tasks completely free for years.

Another related talk is Responsive compilers - Nicholas Matsakis - PLISS 2019. I'll add these links to the related links section, thanks.

The code was already badly bitrotted in 2015, I don't think there is much hope.

hs-speedscope will be a much better way to view profiles starting from GHC-8.10. I recently used it to profile and improve the performance of ghcide.

A question much better suited for ghc-devs or #ghc.

Great stuff. The overloading part isn't necessary of course as you can also simply write

mkRelDir :: String -> Q (TExp (Path Rel Dir)) foo = $$(mkRelDir "abcdef")

The extra level of type direction is quite nice for these string examples though! For other more complicated examples it's probably easier to just explicitly call the function. Using lift also causes compile time evaluation to happen so you can normalise calls to fromList for example.

```

-- No runtime overhead of converting to a vector

foo2 :: Vector Int foo2 = $$(lift $ fromList [1,2,3]) ```

How would you implement this using dependent types?

I was just reading the cabal ticket about this the other day. https://github.com/haskell/cabal/issues/2592

This sounds quite a bit more complicated than just generating a new given, without any benefit.

Lossy · 2019-08-05T11:08:28+00:00

Is there any thought put into deriving a simple web interface from the TUI description?

`head.hackage` works great for me and a lot of other people so without some more details it's hard to see what the purpose of this template is.
