+1. I gave a talk in the eBPF room couple years ago and it was an awesome experience. Sometimes I get jaded being a professional software engineer but FOSDEM reminds me there’s a passionate community behind what we do and it’s great to reconnect with that community, and to share some knowledge with others.

Fable was really excellent before the whole fiasco with the US government. Once they brought it back it was not the same at all. I have switched over to ChatGPT now for most things, its answers are way better than Fable in my experience. I still use Opus 5 for purely coding tasks.

This is why I think open weight models will win out in the end. Right now there’s too much going on behind the scenes with the models. Day to day you never know if you’re going to get smart Claude or dumb Claude.

The issue is long term, high capacity storage. To store enough energy to last an entire winter using batteries just isn’t practical today. I think you’d need around 100 power walls at today’s capacity to make a house completely off grid, meaning you store excess solar from the summer and draw it down in the winter. With hydrogen stored in pressurized tanks, a 20 m3 tank could be enough to last the whole winter, which seems much more practical than 100 powerwalls.

I think this could be a solution if you wanted a fully off grid, solar powered house, or perhaps if we collectively decide to generate more electricity at home and not rely so much on the grid.

I agree, I wish more work was being done on building a hydrogen economy. Hydrogen can be generated sustainably, is a great way to store excess energy from renewable sources, can be transported, and as a bonus can be mixed with hydrocarbon fuels to be used directly as a heating source.

As an example, a house in NH can generate a lot of excess solar power in the summer months when it uses hardly any electricity. If all that energy could be stored as hydrogen, in the winter (when solar power is less due to the far northern latitude and snow covering the panels) it could draw down on the hydrogen to generate electricity and also use it for a backup heat fuel.

Newb question but I’m curious what would help it to run faster? Would it need more vRAM or just system memory?

That’s very interesting, thank you for sharing. Looks like it could be a very useful tool for testing high performance networking.

I wonder if something similar could be done using TC BPF instead of AF_XDP? My only reservation about AF XDP is that it requires a special NIC to support it, so it may not be useful for a “regular Joe” user. I wonder if TC BPF would also work since it similarly bypasses the Kernel networking stack, I believe you can put packets directly into the NIC TX queue for transmission

Has anyone ever claimed otherwise?

Another nice benefit of this would be location tracking. Once you had established the database of tools and the CV setup to recognize them, you could ask the LLM, “where did I last place my Stanley knife”?

Exactly. The challenge isn’t getting the LLMs to make sure they validate their own code. It’s getting the LLMs to write the correct code in the first place. Adding more and more LLM-generated test code just obfuscates the LLM code even further. I have seen some really wild things where LLM jumps through hoops to get tests to pass, even when they actually should be failing because the logic is wrong.

The core of the issue is that LLMs are sycophants, they want to make the user happy above all. The most important thing is to make sure what you are asking the LLM to do is correct from the beginning. I’ve found the highest value activity is the in the planning phase.

When I have gotten good results with Claude Code, it’s because I spent a lot of time working with it to generate a detailed plan of what I wanted to build. Then by the time it got to the coding step, actually writing the code is trivial because the details have all been worked out in the plan.

It’s probably not a coincidence that when I have worked in safety critical software (DO-178), the process looks very similar. By the time you write a line of code, the requirements for that line have been so thoroughly vetted that writing the code feels like an afterthought.

I am curious, what explanation would justify a full closure of the airspace over a major us city for 10 days, in your opinion? That is the real screwup here. Whatever justification they are giving is entirely beside the point. Closing the airspace, even to emergency medevac flights, is negligence.

They have confirmed it was for testing a counter-drone weapon. They did not say why they set it to expire in 10 days, that part seems like it was probably a mistake.

Someone probably just screwed up

Quite literally, the previous post on this blog is from 2024 talking about what a revolution the Rabbit R1 is. We all know how that turned out. This is why I give every new trendy developer tool a few months to see if it’s really a good thing or just hype.
