Re: [Nix-dev] syncthing questions

[Sergey Mironov]

OK, I have solved my syncthing-related problems. It turns out that I
misused service.syncthing.dataDir config option. I thought it is
pre-defined data directory to syncronize, but it is configuration-only
directory in reality!

Sergey

Solution in case someone has the same issue in the future: it's nothing
to do with NixOS. Alexei was correct. Got a new stylus (HP instead of a

Re: [Nix-dev] What license does the content of the nixos wiki and the manuals have?

[Joel Moberg]

For nix, nixos, nixpkgs and nixops, see source repos and the file COPYING.
I think this license applies if there is no other remark on the manual
page. I can't find any license info at the wiki. And then I think the
'default' license is that the author owns the rights to all material. But
the wiki have many authors..

[Nix-dev] What license does the content of the nixos wiki and the manuals have?

[Matthias Beyer]

Hi,

I cannot find any hints under what license the nixos wiki and the
manuales on nix, nixos, nixpkgs and nixops are published.

The pages "About Nix wiki" and "Disclaimers" as well as
"Privacy Policy" on the nixos wiki are non-existent.

So does anyone know something about this topic?

Re: [Nix-dev] syncthing questions

[zimbatm]

Hi Sergey,

Have you setup syncthing using the config.services.syncthing.enable = true
in /etc/nixos/configuration.nix ?
The service is creating /var/lib/syncthing by default. This is a better
place to put the files, home folders should be private.
Cheers,
z

Re: [Nix-dev] nixpkgs haskell system got into inconsistent state broken

[Thomas Hunger]

It's possible you hit the infamous non-deterministic package hash
generation [1] for which Peter collected data recently [2]. AFAICT the only
solution is to remove and rebuild or refetch all haskell packages.

This bug has high priority for GHC 8 so I hope it'll eventually go away.

[Nix-dev] syncthing questions

[Sergey Mironov]

Hi, List! I have two questions regarding Syncthing synchronization
service. They may be not strongly related to Nix but I'd like to ask
here before going to the upstream's forum.

1) I've upgraded NixOS installations on both desktop and server
workstations recently. After the upgrade I noticed that syncthing IDs
were changed, so I had to re-setup the connection using Web-GUI. Is it
possible to preserve the IDs ? Or should we think about making this
type of configuration static by providing NixOS wrappers for
'device'/'folders' options? (I am not sure if it is possible or not)

2) I keep my synced data in the /home/syncthing folder and I want it
to be of 'syncthing:users' user/group with 770 permissions. Older
NixOS setup seems to handle it well, but the new one seems to reset
the permissions to 'syncthing:root' 700 every hour. Could it be a
systemd new behavior or it's the syncthing who does this?

Sergey

[Nix-dev] Nix logo poll results

[Tim Cuthbertson]

Hi all,

Thanks to all who voted on the nix logo poll[0]! The voting has more
or less dropped off after about a week and about 140 responses, so
this seems like a good time to reveal the results.

[0]: 
https://docs.google.com/forms/d/1oMKuPCIz5bmUokrN6mllYpIDH7cmVQTzuZAcUdGH1HM/viewform

Google provides some neat graphs on the responses:

https://docs.google.com/forms/d/1oMKuPCIz5bmUokrN6mllYpIDH7cmVQTzuZAcUdGH1HM/viewanalytics

### Main takeaways:

7% of respondents definitively want to keep the current logo. 32%
don't mind either way, and 52% are keen to adopt one of these new
logos. A further 9% want to change, but not to any of these options.

The favourite logo option presented is clearly the Hexagon outline +
alternating colours. 50% said this was their favourite logo, and 80%
consider it an improvement on the current logo. 9% consider it worse
than the current logo, and the remaining 10% are ambivalent.

The response to the "should we have a gradient version" is mixed. Half
the respondents don't care, while 28% being pro-gradient and 22%
pro-flat. That's a slight lean towards pro-gradient, but could
probably come to an executive decision if anyone wants to make it ;)

There were quite a few comments about the font - if anyone is keen, it
sounds like there's some enthusiasm for changing the font as well. If
we're changing the logo I'm happy to explore new fonts at the same
time, but I'm also happy for someone else to do that - I don't have
such strong opinions on the font.

### Raw responses:

https://docs.google.com/spreadsheets/d/1nevqPzHhGXBAfB_I_4ESRArASPfr-2kYqzAIWz5Av9c/edit?usp=sharing


### Next steps:

So: the question is, what next? Is this enough of a critical mass to
proceed with a logo change? I feel like it is, but I am of course
biased ;). If we want to change the logo, how would we go about it?
Who do we need to get involved to make it happen?

Thanks all,
 - Tim.

[Nix-dev] nixpkgs haskell system got into inconsistent state broken

[Miguel Negrão]

Hi

This week I encountered a situation where when I tried to build one of my
own packages which was working fine before, it would fail claiming that
every single Haskell package it needed was missing:

http://pastebin.com/agqw9dn2
http://pastebin.com/Vyqc5U3e

I had not changed anything or installed anything in nix for quite a while,
the only thing I can think that could have caused this was that my
filesystem had died (btrfs) and I had to restore from backup the whole of /.
I have not used binary cache to build any of the haskell packages, they were
built from source.

Is it possible that the restore of / via rsync could have caused this ?

In the meantime I had did a rm -r /nix and installed everything again and my
system is working again, exactly as before this issue (I had everything
specified in my config.nix), which is a testament to how easy it is to
rebuild a system with nix if you have a declarative description of your
packages.

Thanks,
Miguel

Rereading the original link I realize that I misunderstood what they were
proposing, indeed it does not fix the type of issues I'm mentioning. I think
the issue I was thinking of is the "diamond problem" [1]:

package A
 / \   
package C   Package D
|   |
package Ev1 PackageEv2

which can cause errors such as:
Couldn't match expected type `bytestring-0.9.0.4:Data.ByteString.ByteString'
against inferred type `bytestring-0.9.0.1:Data.ByteString.ByteString'

Actually, like it is mentioned in the post, this is solved in nix, because
you can install another version of D which uses Ev1 instead of Ev2. 

best,
Miguel
