Similar position as you (mid 2012 macbook air, 1.8 GHz Intel Core i5, 8Gb of RAM, 256Gb SSD + 256Gb SD Card). I've upgraded its battery twice, last time this year, for 60 EUR each time, and its hitting > 9h of battery life right now

There is no Microsoft Office, Photoshop, Illustrator, ... on all three. If all you need is a text editor and a web browser, you pretty much could have been using all three systems for 20 years already.

Dude, I bought a max spec'ed macbook air mid 2012 with 256Gb SSD + 256Gb SD Card, a dual core, and 8Gb of RAM, for ~1600 EUR in 2012. In 2018 I would have to pay 2000 EUR for 512Gb SSD, still a dual core, 16Gb of RAM that is only sligh

Are these services free? We currently test Rust under qemu-system for FreeBSD and have no real good solution for OpenBSD and DragonflyBSD. It would be very interesting for us to do "native" testing.

No, as much work means that you can't use 99% of C++ in C FFI. You have to fully instantiate template functions, template structs (you can pass `std::vector` to C FFI), etc. before you can expose them to C. If you are writing C++ in su

Rust has been able to target RISC-V for half a year, so LLVM must have been able to target it for even longer...

Jokes aside. Since February you can already buy RISC-V SoCs that run Linux... at pretty high prices, e.g., https://www.crowdsupply.com/sifive/hifive-unleashed costs 1000$ bucks and the expansion board costs 2000$... St
