Re: [Tails-dev] Proposal: Redmine workflow change

Good idea! Works for me.

What would happen to tickets that go back-and-forth between the main
author and the reviewer? Would they stay in "Needs Validation" or go
back-and-forth between "In Progress" and "Needs Validation"?

Sounds much simpler, awesome! +1

I quite like this feature and have set up filter rules in my email client for 
the resulting redmine notifications I receive so I don't miss them. However, I 
wonder how this works out if you don't do something like that. I also fear that 
the ad hoc tracking of "mentions" that you propose above is easy to forget.

I just had a half-baked idea that might have some merit: say I work on ticket X 
and need info about "foo" from intrigeri. Then I just create a subticket Y of X 
called "Info needed: foo" and assign it to intri. When intri has posted the 
information about "foo" to X he can then mark Y as resolved.

Cheers!

I'm all for simplifications of workflows :)

Re: [Tails-dev] Security implications: moving code from Verification Extension to our website

Ideally we'd only maintain one of those, but I think your idea is good:
if we could increase verification by having an internal mechanism, this
would be an improvement. However, the question remains: what happens if
an attacker controls the website?

I'm not quite sure what you mean but we regularly and automatically
check that all the mirrors serve correct images ({IMG, ISO} + SIG are
checked), independently of the individual verification that users should
do when downloading an image. But there might be a delay with us
reacting to this if a mirror is compromised.

I'm not a regular contributor, so you should weight my opinion very
lightly, but this all sounds quite to me.

The more i see technical systems in actual use, the more i think that
simpler tooling is better and more likely to be used effectively, even
if it is not as nuanced.

The argument for nuance is that it can typically represent reality more
closely than the simpler view.  But if, in practice, that nuance isn't
widely understood, or is accidentally misused, then that particular
advantage is actually a disadvantage.

Your proposal sounds simpler and therefore more likely to be accurate.

Correct.

The JSON file can technically contain many files and their checksums.

Agreed.
