Hello *,
Welcome to the GHC Weekly news. And it's just in time before you go
out and eat lots of candy and food.
* David Feuer and Joachim Brietner spent some time this past week
talking about more optimizations for Haskell code for fusing code, and
creating better consumers and producers. This
Thanks for the quick response, yes it's up. Next time I'll check the status
page which I was unaware of.
Thanks again

Yes, unfortunatley, hackage was down. See
https://status.haskell.org/
I think it's being brought up right now by our fearless
volunteer infrastructure rapid response team (they are drafting!).
Please try again.

When I type
cabal update
I get

Anybody else seeing this?

I already created such a wiki page some time ago:

Ok, it's starting with git 2.0.

Right. But don't trust me, try with --dry-run.

You need 'push -f' to force overwriting the old version

You will most likely need to add a '--force' to your push, to overwrite
the branch in the remote repo.

Friends
I am working on wip/new-flatten-skolems-Oct14. I have pushed lots of patches
up to the main repo.
Now I want to rebase to clean up. Can I just do a local rebase and then git
push? Nothing special about the push?
I know that will confuse anyone who is pulling from that branch, but I'

As people respond on this thread, would you be willing to capture what you
learn in a wiki page in the Commentary? That way, your successor would have at
least those questions answered right away. Somewhere under here
https://ghc.haskell.org/trac/ghc/wiki/Commentary/Compiler would be good

I'm working on core-to-core optimisation that improves code when something is
used multiple times.
I fear that in practice it might not be beneficial to transform thing that are
used just once.

Thanks guys. I've read the wiki page about demand analysis and things start to
make a bit more
sense now.

Nick,
Where in the wiki would you have looked for it?
This isn’t at trick question. It’s quite hard to know where to record info!
