I built a window vent with a variable-speed computer fan and an esp8266 that communicates with a CO2 monitor and raises the speed when the CO2 gets too high. I have a very fine mesh on the window screen that's designed to filter out pollen and dust. It works really well. I usually only turn it on at night, because that's when my wife and I are both in the room and the CO2 can really build up.

This used to mean something, but I don't think it does anymore.

I noticed this a few years ago and decided to start giving any automated systems a special email address so I can filter automated email into a separate folder. I only give out my personal email address to actual humans. Its been a huge improvement to only see human-written emails in my inbox.

I've been a mc user for many years, but lately I've been using dired in emacs. It's quite powerful and intuitive to me.

I knew npm was a train wreck when I first used it years ago and it pulled in literally hundreds of dependencies for a simple app. I avoid anything that uses it like the plague.

In my experience, this is how it goes whenever there are more than 2 people in a conversation. The speed of the topic switching defaults to the fastest processor in the group, basically excluding any slow processors from the conversation.

The blog post says they'll be using Application Templates to implement this:

So touchscreen support will be like a mode you can switch on. I don't think desktop users will be affected.

jbd0 — Mon, 09 Jun 2025 13:48:41 +0000

Before I started self-hosting my LLMs with Ollama, I imagined that they required a ton of energy to operate. I was amazed at how quickly my local LLM operates with a relatively inexpensive GeForce RTX 4060 with 8GB VRAM and an 8b model. The 8b model isn't as smart as the hosted 70b models I've used, but it's still surprisingly useful.

It's ugly because an "accept cookies" pop-up obscures half of the page.

Or different instances of the site on the same server, serving different locales. Only one instance would be running at a time.

I thought they were overpriced until I looked into building one myself. The heat sinks were going to be really expensive. The LEDs and lenses weren't cheap either.

I use Blender for CAD. It's not designed for that, but I've developed a particular workflow that fits my needs quite well. I use it to design everything from small parts to buildings. I've used FreeCAD, but it's just too time-consuming.

You're so wrong. With only protein and fat, they would not be able to gain much weight. I've tried to gain weight on low carb/high fat, and it doesn't work. I was uncomfortably full after every meal. My tracking showed a significant calorie surplus, but my body wasn't absorbing it. Adding in more carbs made a huge difference. Hormones tell your body when to store fat.
