The key to happiness in WiFi is that all the stations have to "hear" each other, or the listen-before-talk algorithm can't work and you end up stepping on valid transmissions that you can't hear. This ruins it for the s

Yup, exactly. Compare the price of a PC power supply, which outputs a very smooth constant voltage, to a microwave oven. The microwave oven is cheaper, and uses all 1800W of your circuit. A DC power supply that does that is much more exp

> Since WiFi and a microwave operate at the same frequency (2.4GHz), we ran our leaky microwave at full power to block out any persistent network signals in the air. Incidentally, WiFi tries to intentionally avoid this interference. Mic

Guess what happens when allergens irritate the inside of your nose? You get congested.

I take it every day; deviated septum and allergic to everything even after decades of immunotherapy. Maybe I should get surgery. But this is easier.

It's a big pain. The prescription line at my pharmacy is never shorter than 15 minutes. Thus the drug is $11/month but costs me $60 in time to wait in that line. Meanwhile, other drugs are just mailed to me, including my prescr

Just to answer your edit, nope, I wasn't mixing distros or anything. It would either be all Nix or all Debian.

This has always made me sad, but I think you're right in a lot of cases. What I've always tried to do is to focus on basic productivity; make sure everyone has everything they need to do their work, and that most people do it in

I think this, or something of equal complexity, is probably the right choice. I have spent a lot of time helping people with their dev environments, and the same problems keep coming up; "no, you need this version of kubectl", &q

This turns a 1 hour task into a 1 day task. Fast feedback cycles are critical to software development. I don't quite understand how people get into the situation where their work can't fit on their workstation. I've worked

I'm guessing that Zig, Rust, Oden, and "etc." didn't exist when they started the codebase. Now they need to keep moving in their imperfect state. I don't think anyone would start a large company on Ruby today. (T

Personally, I like a fixed uint8 or uint16 representing the length of each segment. Then, there are no forbidden characters or quoting required. Maybe I want to have \0 in my password.

Yeah, the M4 is apparently the fastest CPU on single-core benchmarks. If you want a fast laptop, you have to get it. Not being forced to use Mac OS would be nice.

It depends on the game. If there are a lot of game simulation calculations to do for every frame, then you're going to be CPU constrained. If it's a storybook that you're walking through and every pixel is raytraced using t

When I was there, way more than 25% of the code was copying one proto into another proto, or so people complained. What sort of memes are people making now that this task has been automated?

Even Windows has this with PowerToys. I use 3 monitors but would switch to 1 if games respected the dimensions and 8k displays could refresh at 360Hz.

I think it can be challenging to get that much data to a single database. For example, you probably don't want to send every "someone moused over this ad" event in Japan to a datacenter in us-east-1. But if you do the aggre

My understanding of what happens is that chatting with an LLM is implemented as <send all chat history> <ask for next sentence>. There are then keywords handled by non-LLM code, like "execute this Python script" or &q

Yes, the whole point of having a ham license is the permission to build and use your own equipment. The compromise vs "buy some spectrum for 8 trillion dollars" is that you can't use ham radio for commercial (or musical) purp

I don't think you expect to stop taking the drug. It's a for-life kind of thing. If a prescription for "lifestyle changes" were a drug, it would be one of the least effective drugs ever made. I read something directed

I'm also a ham radio operator (extra). No ham for commercial purposes, which is what this would be, so I went the unlicensed route.

Cell signal isn't always everywhere. A friend of mine wanted to shoot a documentary in the middle of nowhere. I made a couple of modules that have GPS and LoRa radios to show where the other group is at all times. Easier than readin

Makes sense. "I am session abcdef12345" always seemed significantly guaranteed to me, but in a world with ad blockers and third-party cookie restrictions, using heuristics is the only way forward. It's somewhat scary how muc

Before I get too alarmed someone would have to tell me how an adsite.com cookie is being sent to adsite.example.com. This workaround seems to let adsite.com profile me as well as example.com already can, but it loses the ability to correla
