Yeah, kind of hilarious to me that this was posted here. I suppose if you’ve never encountered control systems at all before they are quite simple, elegant, and cool, but I’m surprised any technical person hasn’t come across them at some point.

If you’re cognizant of the sycophancy and not a total narcissist then it’s not too hard to figure out with a little experience when the models are just trying to hype you up

Custom built robots are expensive (basically an R&D project in themselves) and inflexible, if you want to update the process you have to redesign your automated system. The dream of humanoid robots is they can adapt to new manufacturing processes like human workers.

Can you talk more about the UI for face/edge selection that you're working on? Is that only going to be in the OnShape/Fusion plugins?

Definitely! I stared with macOS since that's what I use most often and there's a strong tradition of menu bar apps on that platform. If people enjoy the Mac version I'll definitely make a Windows system tray version, then Linux after that.

Show HN: AgentPace – Know when you’ll run out of Claude Code/Codex usage

jrflo — Tue, 16 Jun 2026 13:58:24 +0000

Hi HN! I built AgentPace (a macOS menu bar app) because I found myself constantly doing mental math on whether or not I would run out of coding agent usage prematurely. The idea isn't showing "You have X% left" in the menu bar, but showing your usage trends over time to help you plan and manage your usage. The usage graph makes this glanceable and intuitive, so you can quickly figure out your burn rate without leaving your workflow. Right now it's focused on people with subscription plans to Claude Code and Codex, but I have plans to expand this out in the future. Happy to answer any questions!

Anthropic really has been in a PR freefall since Opus 4.7.

I would love to do this if it didn't require such a huge amount of RAM. And the difference in quality is worth it to pay $20-$100/mo if data retention doesn't matter to you.

New comment by jrflo in "Amazon says its datacenters used about 2.5B gallons of water last year"

jrflo — Sun, 14 Jun 2026 15:58:28 +0000

What drives me nuts about this whole water consumption discourse, is no one ever asks what happens to the water when it's used- it gets evaporated! It re-enters the water cycle as pure water! It's not like it's getting destroyed or turned into some unusable sludge, it'll just rain back down again in a few weeks.

Obviously, you still shouldn't build datacenters in areas that are locally water-stressed as that will add additional burden to the infrastructure.

I feel like this is only slightly worse than booking on any other airline. Even the supposedly "good" ones like Delta do a lot of these tricks. No reason not to, it's basically free revenue for them.

I think drugs is an apt analogy. Hackernews is like alcohol, it definitely can be addicting but generally most people dont have a problem with it. Short form video is like meth

It's not even just kids, this is true for all people to be honest. Not saying we should go back to an agrarian society but maybe unrestricted access to dopamine slot machines isn't a good idea for your brain.

I checked my email and I paid $60 for the 4GB model in 2023. >2x returns in 3 years isn't so bad.

New comment by jrflo in "US Consumer Price Index up 4.2%"

jrflo — Wed, 10 Jun 2026 22:01:07 +0000

Obviously more inflation is bad almost always. The question is how bad. By looking at a graph, you can get a sense for the mean and standard deviation of inflation over time, and this looks to be a small deviation in the grand scheme of things. Of course, no one would call this good, but it's just good to put stuff like this in context.

Who would've thought the $50 pi 5 I bought on a whim would be my best performing asset in the last few years

New comment by jrflo in "US Consumer Price Index up 4.2%"

jrflo — Wed, 10 Jun 2026 18:11:33 +0000

Zooming out tells you this tick up to 4.2% is not nearly as bad as the post-covid inflation, and drastically better than the 70s. Not a good sign, but also not too far outside the historical mean and probably no need to panic in and of itself.

I just subscribe/unsubscribe to the providers each month. I'll definitely check out open router though, I always assumed that subscriptions were heavily subsidized by the providers especially if you're on the top end of users but maybe I should go to a usage-based plan.

That's good to hear. It was legitimately unusable back when 4.7 was released, so I had no choice at the time. I'm sure I'll ping pong back again at some point.
