avhon1on Clamiga: Common Lisp for the Amiga

Almost every commit in the github repository is generated by claude code, so this may be correct.

avhon1on Long Range E-Bike (2021)

Recumbent trikes have the potential for leg suck, but two-wheelers havee no especial safety risks.

> recumbent bikes are expensive

New recumbents are expensive, but used ones are very cheap. Afyer seeing several within an hour's drive of me for $300, I got a Rans Rocket for $100. Appparently it had been available (but poorly advertised) for two years.

A little while after I became "the guy who rides a recumbent", I was given a Rans Vivo for free, because the owner hhad determined that the expected sale price wasn't worth the time and effort to sell.

> My ebike's minimum speed for the motor is 15kph

That is a flaw in your ebike. Weird and dangerous.

avhon1on Long Range E-Bike (2021)

The cost wouldn't necessarily be in the bike, but in requirements for mandatory paid registration, licensing classes, insurance, inspection, and safety equipment.

Wattage is basically meaningless. There is nk standard way to measure it. Almost all "250 watt" ebikes consume much more than 250 watts of electricity at full throttle, and can produce much more than 250 watts of mechanical output for seconds or minutes at a time.

avhon1on Parametric CAD in Rust

To rotate the view in SolveSpace, you need any one of these:

* a keyboard's shift key and a right mouse button, or * a middle mouse button, or * a 3D mouse.

I've done some work in SolveSpace with a Wacom tablet, by binding the stylus's buttons to the middle and right mouse buttons. SolveSpace is a pretty simple program, so you don't need to dig deep through the UI to get to all the functions. Lost of the often-used functions have keyboard shortcuts, but I don't think there is anything that is only accessible through the keyboard.

Depending on what you aim to do, you might be interested in keeping up with Blender's currently-in-development tablet mode:

avhon1on Parametric CAD in Rust

SolveSpace does have some ability to control the color and fill of areas. It's nowhere near as powerful as Inkscape, but enough to make simple diagrams. The exported SVGs can also be edited in Inkscape.

for simple learning, I invite you to consider SolveSpace

SolveSpace is available in library form. It uses NURBS to represent surfaces, with triangles as a fallback.

avhon1on Parametric CAD in Rust

Just because you type dimensions in doesn't mean it's parametric. If you're manually patching meshes, you're almost certainly not doing parametric CAD! (This does match with my memories of SketchUp, beck when it was owned by Google. I had to fix holes and overlapping geometry by editing the .STL files in Blender before any of the primitive slicer programs could process them.)

OnShape and Fusion360 are fully parametric CAD programs. Another free-tier closed-source one is Siemens Solid Edge (the "Hobbyist" edition). FLOSS parametric CAD programs that are reasonably usable are FreeCAD (complicated but powerful) and SolveSpace (an 80/20 sort of tool -- nowhere near as powerful, but vastly easier to use).

FWIW, the FLOSS CAD program SolveSpace can generate parametric sketches and export them as SVG files (file > export 2d view)

FreeCAD can do this. So can all of the proprietary parametric CAD programs I've ever used, some of which (PTC OnShape, Siemens Solid Edge, Autodesk Fusion) have usable free tiers available.

avhon1on Damn Small Linux

So you can use as little CPU and RAM as necessary to browse the page you want to read at any given moment.

avhon1on Turtletoy

Writing an infinite "hello world!" loop on an Atari 800XL was my first programming experience... in the mid-2000s.

avhon1on How I block all online ads

and if you find a video that hasn't had the ads tagged yet, the UI for it is pretty easy to figure out.

Chromebooks are ubiquitous in U.S. primary and secondary schools

avhon1on Average DRAM price in USD over last 18 months

As someone who used the HTML gmail interface right up until google pulled the plug: the JS version is much slower to load. Every morning, I get to have about 10 seconds thinking about how it used to be faster.

If each step was 1 frame, and the video played at 240 frames per second, the video would last about 17.5 years

avhon1on Migrating Dillo from GitHub

That feature seems common to other git hosts / forges. For example, here's one of Dillo's files, from a few commits ago, from their cgit-based host

avhon1on Migrating Dillo from GitHub

No doubt this is desirable. However, adding all the CSS features required to support cgit may have been a lot more work than editing cgit's CSS. It's an attempt at avoiding yak shaving; adding recursive sub-projects that balloon a project's scope of work far beyond the original plan.

Dillo is actively developed, and the project of "migrate away from github" is complete, so now other work can be started and completed (like adding the CSS features required to support mainline cgit).

avhon1on Migrating Dillo from GitHub

Redundancy for read access to the source code is a concern for Dillo. Some years ago, the domain name registration lapsed, and was promptly bought by an impersonator, taking the official repository offline. If it hadn't been for people having clones of the repository, the source code and history would have been lost.

How do people find your online project and know it's you (instead of an impersonator) without relying on an authority, like GitHub accounts or domain names? It is a challenging problem with no good solution. At least now the project is alive again and more resilient than before.

Child safety locks do this. They prevent the rear doors from being unlocked and opened from the inside.

Water mist fire extinguishers are nice. They are much more able to cool lightweight, flammable objects, and pose less risk of causing electrical arcs.

They were using carbon dioxide fire extinguishers, which are expensive (a couple hundred dollars, see [1] ) and not common in homes.

avhon1on Where do the children play?

In the United States, throttle-only ebikes that go up to 20 miles per hour (Class 2 ebikes) are legal pretty much everywhere. They're required to have functional pedals, but no pedal assist function is required.

It took me a bit of searching, but sure enough:

Seems very tedious to actually use, but very cool to have it in the unassuming wristwatch.

avhon1on Perkeep – Personal storage system for life

What's wrong with that? That seems like more than one release per year, and all roughly compatible with each other.
