This should be higher up for anyone considering DACs for homelab use. I had a lot of issues due to this when mixing Aruba switches with Intel nics in my rack. Ended up going to fiber and SFPs.

I find it bothersome because the system incentivizes giant megacorp monopolies. If you are small you'll have to pay taxes like everyone else, but once you hit some threshold of huge enough, we'll let taxes slide so you can get another leg up. A datacenter this size isn't going to provide more economic benefit than 50 datacenters 1/50 the size, but only one of them gets special treatment.

Combine that with the fact that large corporations constantly find ways to avoid paying taxes and its hard to be positive about this kind of thing.

If you get a quality tig welder aluminum isn't too bad. It's definitely more difficult than steel but I taught myself to weld AL without too much trouble. Practice on some scrap for sure before your bike - it'll be easy to blow a hole in thin bike tube.

The biggest challenge I've had in welding aluminum as a hobbyist is that I rarely know what aluminum alloy I'm working with. Most things don't say what type so we're left guessing what filler is appropriate. If you use the wrong filler it could be prone to cracking again in the future.

Also for thicker aluminum preheating is very important. The aluminum transfers heat away very quickly so you get cold lumpy welds if you don't have both parts pretty hot at the start.

I don't know Bolt touchscreen specifics, but a lot of electronics in newer cars are paired to the id in the cars BCM or security module and installing replacement parts requires activation/re-registering using proprietary dealership tools.

That could easily be part of their prompt. I just did a quick test telling Copilot to "add a few spelling and grammar mistakes to look like a human wrote it" and it does a reasonably convincing job.

You might want to look up the max thickness and other common issues hobbyist level laser welders have before purchasing, or at a minimum wait for the laser welders to mature a bit more. You'll spend less than half and be far better served with a cheap tig welder at this point in time.

I don't think its unreasonable to ask politicians to be familiar with how the machinery they are regulating functions and is used.

To use your heroin example, this is akin to banning spoons or needles because they heard those are tools of the heroin addict. It shows a lack of understanding on the part of the regulator and has a far reaching effect on people legally using the items.

My legs are long enough there isn't room for them to press against the back of the seat. I'm either manspreading into the crevases between seats or in foetal position with my knees halfway up the seat in front of me. A person reclining is excruciating in the former, but in the latter position at least the person in front can't recline as there's no physical space for my body to become more compact. Flying is hell.

Each material has its own issues. Kevlar is very difficult to work with (need special scissors to cut and you can't sand the finished product), Dyneema is sensitive to UV degradation. Carbon is $$$. Basalt sounds like the sweet spot for some of my applications but afaict it can't be purchased by the yard like most materials so is essentially unobtainium to a hobbyist who can't afford a $1k or so roll of material.

Exactly this. I make kayaks and basalt would be the perfect middle ground between FG and carbon where the boat will get dinged up in rivers. Unfortunately its nearly impossible to obtain in small quantities for a hobbyist.

It's a false equivalence to equate humans (even "super-recognizers") with a computer when it comes to matching large quantities of faces with names/PII.

At some point the numbers get big enough that you wouldn't be able to get the pictures of faces in front of the people who would recognize them fast enough.

Lest this mislead anyone, that's a touch panel not a thermostat. Pretty much all of Crestrons panels and Processors (the brains of the system) ran some form of windows embedded. They've switched the current generation over to linux I believe.

I wouldn't consider a Lutron light switch to be a direct comparison to Crestron. Crestron targets the ultra wealthy by being very reliable (assuming setup by a competent programmer) with unified control of pretty much everything household - shades, lights, audio, video, etc. They're aiming for the kind of people who will pay a premium to make sure their house just works, every time, without having to deal with tech issues.

You could certainly bodge together a similar system for less money, but the controls won't be as nice and it'll be nowhere near as hassle free long term. HomeAssistant and competitors have really been catching up in the past few years though, i'm excited to see competition in the market. I wish they could all play nice together with reasonable APIs :/
