Two years ago while walking from a plane to the terminal I dropped my “rugged” Android device less than a metre onto the tarmac and it smashed. I took a punt on moving to an iPhone. I was worried about the walled garden I’d heard so much about and believed, I plan to write about that experience more generally in a future post (spoiler: it’s mostly unfounded).
We’ve come a long way in usability of these tools since my first exposure using Password Safe. Services such as Bitwarden, LastPass, 1Password, and so on have made it extremely easy to get on board with using a single master password to decrypt a database of passwords (that are ideally random, long and unique), clients working across multiple devices and OS, vault storage in the cloud. They also…
So firstly I do in fact quite like Markdown and generally enjoy writing documents in it. But similarly to YAML it’s simplicity and generally widespread use has resulted in it being overused and beaten with a large hammer to fit into places it was never really fit for.
There are unfortunately very few options today, and in 2022 things only seem worse. Regular stock of HP 35S and 12C models has dried up in the last year, this is hopefully just due to pandemic and semiconductor shortage nonsense and we will see a return of these to production. Perhaps if we’re lucky maybe we’ll see something this year for the 50th anniversary of the HP-35.
This post is a copy from an old gist I wrote up a year or so ago. It’s my basic understanding from a software engineers PoV of what’s going on in a very simple ECU for a naturally aspirated petrol engine you might find in a motobike or an older car. Some thoughts around tuning and so on.
The 16C (or DM16L) is a computer scientist model and not a general scientific calculator, it does not include an exponent function, either arbitrary yx or x². The correct thing to do here is obviously use a suitable device, but for fun I’ve implemented an exponential program on this model. This post documents some of that journey.
