cmlars··on Ask HN: What are you working on? (September 2026)
I’m working on OttoCAM (http://ottocam.com) - a Mac/Windows CAM app that aims to make CAM for makers/diy/hobby folks as easy as slicing for a 3d printer.

I wanted something that I could load in a step file, push a button and have the CAM just “happen” (while still having overrides and custom controls).

I build combat robots and am a Mac user. I was frustrated at the limited CAM options (fusion 360 is bulky, crashy, slow. kirimoto and many others only do STL files and don’t have adaptive tool paths).

I’ve been working on OttoCAM for the last 8 months. It’s free while in beta, and when it does go paid will be a single affordable purchase (like Lightburn).

cmlars··on Type-driven design, test-driven design
I’ve stumbled into type driven design a few times and found it nicely productive. But of course it just tells me that the same of the function output is correct not the content.

cmlars··on Facebook: Free as in Bullshit
> Without personalized ads, Facebook data shows that the average small business advertiser stands to see a cut of over 60% in their sales for every dollar they spend.

It seems like the not-so-thinly veiled complaint is that Facebook wants to change what they’ve been charging but that their service will no longer provide the value it once did.

That doesn’t sound like an Apple problem to me.

cmlars··on Apple Silicon Mac Is About to Kill Web Apps
I would wager that that vast majority of electron app users, have no idea they are using an electron app and wouldn’t care if they did. I’m inclined to believe that the animosity towards electron is largely held by a pretty small minority.

As a developer I use several electron apps daily on a MBP, I never give them a second thought.

The inelegance of high memory consumption is far less infuriating than the many product and UX sins committed by apps.

cmlars··on Show HN: PatchGirl – QA for Web Developers
I worked at a salmon cannery in Alaska for a summer. On the canning line there was the patch station, staffed by “patch girls.” Open cans, freshly filled with fish, would come down the line to each station at about 70 per minute. They were automatically weighed. If they were too heavy or too light you’d “patch” them with extra fish to bring them on par.

This station was very fast paced, precise, and very stressful. And had a small pay increase to account for what a demanding position it was.

The role was open to anyone but when I was there it was all women (and usually was). I was told it was because they most often had the ability to stay calm in the never ending onslaught of cans and still do precise work for hours on end.

I (as a man) worked on at this station for a few days, but couldn’t handle it. It was bonkers hard and those women were beyond impressive.
