Re: [Nix-dev] Set up a Sufficiently Powerful Build Farm

This is great news :) Rob, do you know how much of a difference the additional Mac Minis have made? Also, to which address can I ship a Mac Mini? If another Mini would make a difference, I'd be more than happy to buy and ship one to the foundation. Charles On Wed, Dec 23, 2015, at 12:12 PM,

Re: [Nix-dev] Set up a Sufficiently Powerful Build Farm

Hi, another option that I didn’t mention but researched was looking for hosted Mac machines, but I find those offensively expensive (around 60€ per smallest mac mini per month). That means the price of a machine every 10 months. Cheers, Christian > On 22 Dec 2015, at 10:27, Christian Theune

Please, let's stay constructive. We can't change the hardware industry, but only be a complement to it. On Tue, Dec 22, 2015 at 12:47 PM, Profpatsch wrote: > On 15-12-22 10:27am, Christian Theune wrote: > > I could put one or more mac minis in our office on a reasonable big

I don't have a good sense of how many the foundation can keep, but for now I'm not concerned about us having too many :) the more we get, the more responsive we'll be. As it stands, I think we have two (oldish) Darwin cores on Hydra today, so when my 4-core box
