Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

I had quite a long discussion today on #ipfs, on the topic of using IPFS for sharing Nix derivation output. As Eelco mentioned there is no problem of using IPFS today if we want to reproduce the model that we have today with the binary cache. IPNS can be used to index all the compressed nar

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

This is perhaps a bigger project, and one that would require C++, but I think a lack of the intentional store[1] is the single biggest missing feature for Nix. On 29-10-2015 13:28:10, Erik Rybakken wrote: > The IPFS-thing would be a channel with a binary cache, not a > /nix/store! > I really

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

Even just implementing ipfs as a source mirroring system would be incredibly useful since some packages have incredibly unreliable mirrors. It should be easy to generalize to all of the types of fetches, but you might have to modify the current hashing scheme to match multihash for it to be

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

Point taken. I find IPFS + Intentional store more elegant, but IPFS + extensional store is a step in the right direction, both in terms of conception and implementation work. On Sun, Nov 1, 2015 at 10:51 AM, Nicolas Pierron < nicolas.b.pier...@gmail.com> wrote: > On the other hand, if we want to

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

Yes indeed the Named Data Networking overlay is much more interesting. There are other implementations you can look at other than IPFS as it's the new kid on the block - named-data.net and the now closed source ccnx.org On 29 Oct 2015 18:16, "Domen Kožar" wrote: > > I'd go for:

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

Yes, there is still the trust issue, but one only has to trust the provider of the hashes, not the ones providing the actual files in the IPFS network. Also,if the build is deterministic (another feature mentioned on the GSOC 2015 ideas list), anyone can verify if the hash is valid. One aspect of

[Nix-dev] Ideas for a NixOS-related bachelors thesis?

Hi, for those who don't know me: I'm a 24 year old student at a university of applied sciences in the black forest, germany. I'm in my 6th Semester right now, the 7th (bachelors thesis) starting in Feb/March 2016. I'm writing you people because there might be ideas for a NixOS-related bachelors

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

There are some ideas presented for GSOC 2015 here https://nixos.org/wiki/GSOC_2015_ideas_list, my fave is P2P substitutes. This would mean it would be easy to share a cache and in some cases improve speed. Maybe not all features are needed for this project. For example, a interface where you can

Re: [Nix-dev] Ideas for a NixOS-related bachelors thesis?

This sounds also really interesting. As far as I can tell, IPFS wouldn't protect me against malformed packages, so there is still the trust issue. Anyways, binary cache on a per-user basis (where I only have to trust myself) would be a nice thing for the first step. Will note that as an idea!
