Lambda is actually pretty flexible. You can do anything that takes less that 300 seconds, so that is ok. The biggest thing that I like is that you pay only for the time spent servicing requests, but the lambda actually persists between requests (for free) so you can store data on the hard drive (u

Having just done something similar for something else, you should really look at doing CI in AWS lambda. It is remarkably cheap and (more importantly for my case) requires nearly zero devops once set up. If you suddenly have 10x the CI runs, they can all run in parallel for the same cost. No queues

What sort of hardware would RIOT need for CI? Would a machine with, for example, a pair of E5-2670 (eight cores @ 2.60 GHz), Xeons between 64 and 128 GB of DDR3 ECC RAM, an SSD or two, and maybe some spinning storage suffice or are we talking about something like a highly available cluster consisti

I was going to suggest that you might talk to the Oregon State University Open Source Lab (http://osuosl.org). OSUOSL offers free hosting, email, VMs, colocation, FTP, backup, etc. (both managed and unmanaged) to open source projects. I can't speak to what type of computing power they offer but I k

Just out of curiosity, was this due to a lack of machine resources? How is RIOT's infrastructure (e.g. web and mail hosting) handled; is the hosting donated by one or more of the supporters listed at the bottom of the project's homepage? Would additional hosting resources be helpful? --adam On Tu

Dear RIOTers, due to an immense load of requests on the mailing lists, ten thousands of mails got queued over the last days. This lead to a delay for mail delivery up to several days. After some throttling and performance tuning on the mail server everything should be back to normal and most of th
