I think computed-GOTO is easier to understand and more flexible than Duff's device, but computed-GOTO is not part of the C standard. It is sometimes available as a non-portable extension, e.g. https://gcc.gnu.org/online

I don't recommend doing this. I followed those instructions to the letter, and got a completely broken Nexus 7. I somehow managed to recover enough to reinstall the factory image, but it took many many iterations and blind shots in the

Your TI calculator use 4xAAA batteries, yes? Why not use NiMH rechargeables instead of disposables? NiMH are so cheap these days that they pay for themselves after only a handful of recharge cycles. The other advantage of NiMH is that they

The MacBook Pro 2015 (13 and 15) are amazing, but they have glued-in batteries. iFixIt says it would take 45min to 2h to replace, and it is rated "Difficult". It's the only reason why I won't buy them on eBay. https:&#x

That is a very interesting observation. I am starting to have a similar distaste for the visual noise caused by the ':' in my fully type-annotated Python code. This is particularly noticeable after spending a few weeks writing Gol

I crashed at 2499.1 mph by going sideways for a long long time. How accurate is your physics? If I hit orbital velocity, will I just orbit the moon? What if I hit escape velocity?

Yeah, I've been looking at those TI calculators for a few years, hoping to dabble in some Z80 assembly programming for nostalgia. I've also been eyeing their TI-92, 92II, 92Plus, and Voyage 200 series of calculators. They use the

Your post is a great example why I wish Go lang was named something different. Because you use the lower cased versions java, rust, js, ts, nodejs, deno, etc. But all your 'go' refer to the verb, not the Go language.

As far as I understand, that's a consequence of the automatic insertion of trailing semicolon by the lexer, not a decision by gofmt. It's explained here: https://go.dev/doc/effective_go#semicolons

I find this useful in unit tests where I often find myself duplicating blocks of assertions multiple times. The {block} helps to prevent accidentally reusing variables which are defined by previous blocks of assertions. I rarely use a free-

You are not wrong about WiFi. But sometimes worse is better. :-) With WiFi, I don't need any other technology stack, no hubs, no bridges. I can use my existing network infrastructure. The data packets from the ESP8266 devices get deliv
