@rosssmyth:matrix.org@rosssmyth:matrix.orgAnd the builder resources & cache is just my laptop. Such is life as a software engineer at a hardware company. 15:51:58
@emilazy:matrix.orgemilyfor prod builds too? 🫣15:52:49
@rosssmyth:matrix.org@rosssmyth:matrix.orgI don't really mind building GCC on my laptop. The real issue is GCC on GHA. 15:52:56
@rosssmyth:matrix.org@rosssmyth:matrix.orgOf course. 15:53:03
@rosssmyth:matrix.org@rosssmyth:matrix.orgWorking at a company as the newest hire in like 20 years has some funny things about using contemporary software engineering practices 15:53:53
@rosssmyth:matrix.org@rosssmyth:matrix.orgI am one of two software engineers, and I am the only one who uses version control, the only one who cares even a little bit about being able to build our firmware outside of IDE tooling, ci, and other fun stuff15:54:59
@emilazy:matrix.orgemilycan you give a rough estimate of how many countries' national security depend on the integrity of your laptop? or maybe planes' ability to remain aloft or medical devices' proper functioning? :D15:55:06
@emilazy:matrix.orgemilybut yeah, big builds on GHA is a pain15:55:14
@emilazy:matrix.orgemilyand I assume your company isn't up for paying for the beefier or third-party runners15:55:32
@rosssmyth:matrix.org@rosssmyth:matrix.orgI know we interact with the US military but I'm unsure what we do with them. We have major contracts with the single company that does almost all testing of silicon wafers for all foundries We have many contracts with various medical device manufactuers No aerospace contracts (yet!) And yeah, we just have the cheapest github plan at like $50/year15:56:53
@rosssmyth:matrix.org@rosssmyth:matrix.orgAlso if you drive a Tesla Model X, we have hardware in the rear power seats15:57:09
@rosssmyth:matrix.org@rosssmyth:matrix.orgThough starting next year we will not as they are moving that stuff in-house iirc15:57:34
@rosssmyth:matrix.org@rosssmyth:matrix.orgWe also supply motors for the McDonald's Ice Cream machine.15:57:51
@rosssmyth:matrix.org@rosssmyth:matrix.org* I know we interact with the US military but I'm unsure what we do with them. We have major contracts with the single company that does almost all testing of silicon wafers for all foundries (KLA) We have many contracts with various medical device manufactuers No aerospace contracts (yet!) And yeah, we just have the cheapest github plan at like $50/year15:58:12
@emilazy:matrix.orgemilythankfully there are other components of the Tesla supply chain I am more concerned about, such as Tesla15:58:29
@rosssmyth:matrix.org@rosssmyth:matrix.orgtrue...15:58:36
@rosssmyth:matrix.org@rosssmyth:matrix.orgThey suck to work with!15:58:44
@emilazy:matrix.orgemilyhaha, don't get fired for complaining about your clients on NixOS Matrix :)15:59:12
@emilazy:matrix.orgemily(aren't those the ones famous for always being broken, though?)15:59:28
@rosssmyth:matrix.org@rosssmyth:matrix.orgthey are not our client anymore, the contract expired anyways15:59:35
@rosssmyth:matrix.org@rosssmyth:matrix.orgYes, but it is not our part that breaks!15:59:49
