#1 reminds me of my favourite software quote:

"Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious." -- Fred Brooks

kejaed··on Godot on iPad, Toolbars, Importers, Embedding, Debugger
Same here. I used to have Linux on my iPod and Xbox, MythTV running on a server and Fujitsu netbook. Now between the hockey rinks and soccer fields, I take out my iPad Pro for HN, light photo editing and Netflix if I’m lucky enough to find an hour of down time. There’s enough Linux, QNX, Windows, FreeRTOS, Azure, etc etc all day at work now.
kejaed··on Ask HN: Simple web server with drag and drop upload?
You could try remi. It supports file uploads out of the box and is pretty simple to get up and running:

kejaed··on Minuteman missile communications
As someone who has this week been going through, in detail (is there any other way?), the American CCL and Canadian ECL, this is absolute gold. Thankfully the items in question are no longer on the USML…
kejaed··on Introduction to Calvin and Hobbes: Sunday Pages 1985-1995 (2001)
I grew up with Calvin and Hobbes collections in the back seat of the car on family vacations. I was 14 when the strip ended so I had lots of historical material to go through at the book stores (!).

We have the anthology at home, I think it’s time to introduce the kids (6 & 9) to Watterson, although my son is already an expert at Calvinball without even knowing it.

What struck me reading this piece was thinking about how all the constraints that Watterson faced just don’t exist today, as he pointed out with his “click of the mouse” comment. Constraints can often lead to creative solutions, I wonder where Calvin and Hobbes would go in today’s landscape.

Thanks for this, I’ve wondered if AirPods data could help me track if I’m grinding my teeth, I’ll dig in now!
kejaed··on Thermoelectric Cooling
Might want to put a TEC on the server CPU!
kejaed··on Aerugo – RTOS for aerospace uses written in Rust
I learned lots, worked with some great people, and even certified a thing or two!
kejaed··on Aerugo – RTOS for aerospace uses written in Rust
Here’s a decent textbook that covers the software side in aerospace (DO-178):

You can read up on the system safety side in documents like ARP5754 and ARP4761 and hardware side in DO-254.

kejaed··on 2023 Q4 reliable performance mobile graphics workstation recommendations
During the pandemic we ended up going the thinkpad route due to availability. We now have all our users on ThinkPads from admin to engineering, including CAD capable models for our Mech team. No complaints really.
kejaed··on Ask HN: Graduating from Excel, What's Next?
If you aren’t currently, sounds like you are ready to use an ERP to track such things and link your BOMs to suppliers and purchasing.

You could probably get a BOM into something like Odoo over a weekend to test it out.

kejaed··on Ask HN: Choice of Chair?
Ikea JÄRVFJÄLLET has been good for us.

Keeping an eye on this in the aero, uh, space. Very interesting progress, keep up the good work.
kejaed··on Ask HN: To what extent have digital payments replaced cash in your country?
Canada (Ottawa, ON): the only cash I deal with now is for the kids to learn about or for the odd farm stand. Most farm stands have gone to cashless as well.

Canada’s got the Interac system owned by the banks which has merchant fees lower than credit cards and also provides an electronic money transfer system (email or sms based) for the public.

kejaed··on Ask HN: What is your policy regarding smartphones for your children?
Same here. There’s great stuff for us to watch together, but the mindless stuff keeps getting thrown up over and over again.

kejaed··on Ask HN: Inventory Management Software Stack for Small Businesses?
Sounds like they need an ERP. They could try out Odoo

https://www.odoo.com/

it has an open source version that can be self hosted as well as their cloud hosted version with more modules available.

kejaed··on Ask HN: What is you crazy OpSec techniques?
It can be handy to do this if you have a custom domain for your email and allow for wildcard addresses…
kejaed··on I try to answer “how to become a systems engineer”
I'll generally start with defining the "INCOSE" kind or the "MCSE" kind and most of the time people from one group or the other will know of the one they are close to and little to nothing about the other one.
kejaed··on Requirements (2007)
As a couple others have commented, this post seems a little muddled, and there is a huge formal set of work in the world dealing with what Requirements are, how to elicit them, and then work on design. For example, see the INCOSE Requirements Working Group [0], and their Guide to Writing Requirements [1].

It’s key to remember that the requirements of a Thing are the WHAT and not the HOW. Keep the requirements separate from the Design, then the requirements can stay pretty short and sweet.

It takes a very specific type of engineer or analyst to be able to think at this level of abstraction and not jump into solutionineering (design) when trying to establish exactly what the stakeholders want the system to do.

kejaed··on Generating aerial imagery with your iPhone's Lidar sensor
Same here.

I’d put the table of contents at the very top of the page, so that I know to expect the whole thing.

I’d make the div for the subscribe block a different colour to make it stand out from the rest of the page.

An href link with “continue article…” that jumped down to the next section could help too.

FWIW I almost left the page and missed a really good read because of this issue as well. Glad I didn’t!
