I mean, there’s no way they’re 50w. The best diode lasers for cutting are about 7W. I have a 4.2w laser on my CNC machine for engraving. That’s very powerful, but, nowhere near 50W. For reference, a 50W CO2 laser is typically used in a prof

I really like this product. As others have said, Alex is excellent at customer service. He’s taken my actual phone calls, and really helped out. He’s even implemented some features that helped my sister contribute from Scotland (with no ove

ever seen a welder wearing a mask? I really haven't. But, I've seen many welders breathing stick welding fumes through a lit filter cigarette...sigh. As someone who welds as a hobby, I'd say the bigger danger for anyone weldi

I think there are perverse incentives at work, too. If running the MRI machine cost $100, people would do it. If it can bill insurance $100k, and then any follow up might cost $500k, there is a rational aversion to doing it as it might make

Yeah, those channels are all on my list. How could I forget NYCCNC? He's taught me so much. I grew up with a pretty hands on education in basics of mechanics and woodworking, but youtube and web forums have made it possible for me to s

Agree so much with this. Frank Howarth, Abom79, This Old Tony, Welding Tips and Tricks, Jimmy DiResta, Stumpy Nubs, Stefan Gotteswinter - there's so much great content like this on youtube. TV was never a great place for craft because

There's more to life than statistical significance. We all act on lots of qualitative information all the time, and it doesn't cause us to be catastrophic morons. In fact, we spend inordinate amounts of time trying to teach comput

This seems fine if you wanted to use the SAT to measure an outcome for a given level of inputs . If all you actually care about is the actual outcome though, then this doesn't actually help. I guess there could be both use cases for

There are obviously both factors at work though. Exceptionalism does happen, and it is not purely driven by technology. Outside of climbing, take guitar as an example. The amount of excellent players out there on youtube is amazing. Certain

Agree that there are fewer pensions, however, I think the incentives for rent seeking in 401Ks are still quite strong, and the 401K is quite common for professional jobs.

Wealth inequality is because capitalism. We collectively permit a very large share of wealth to return to owners of capital. Frequently, this is concentrated because of a variety of financial realities (e.g. large amounts of liquid collater

I understand that completely. The way to hold companies accountable is to increase taxes on them, or increase regulations. Companies solve to a given tax burden and regulatory regime. Their solutions can be influenced by changing the rules

Well, Robots may be cheaper, but they may also be more accurate. In my 20 years shopping with Amazon, I have very occasionally received the wrong items, so maybe robots will combat that, or reduce the need to double check, etc. I agree, low

I have found dead, decaying Mylar balloons in nearly every park I’ve ever been to. I found one a mile off the road in panamint valley, and one in sequoia national park. They suck.

motorcycles have different issues. The gear changes are internal inside the transmission, not in the belt drive line. Also, bikes tend to have multi-link suspension with chain growth through the travel. This allows the suspension to be reac

This reminded me of this article - https://mosaicscience.com/story/staying-awake-surprisingly-e... - which discusses treating depression by purposely putting patients into extremely sleep deprived states.

Nothing is really future proof, though. If it makes if 5 years before any major changes, then it will be good. I don't disagree that eventually this could lead to the same kind of vendor lock-in, but, it is also performant, has support

I agree, there is no need for a blockchain. But, that explanation is what has been proposed as the justification for using one. I would counter also that neither of your examples are actually supply chains. FedEx is part of a supply chain,

by abakker 8y ago
The supply chain argument for blockchain basically goes like this: 1. supply chains tend to require lots of coordination, but, also tend to be made of entities that are each individually maximizing for value. 2. In the past, this meant tha

this is kind of flippant, but I suspect that a big part of it is that remaining rational and skeptical, and trying to be belief-free is exhausting. Rituals - even things like having morning coffee or an after work walk are things that I can

Well...it doesn't. Members of corporations absolutely can be and are convicted of crimes. The issue is really whether corporation itself, as a legal "person" can be convicted, and if so, what does that actually mean, legally?

This feels like "I can't define agile, but I know it when I see it"...or just a wonderful example of the No True Scotsman fallacy. Agile is basically implemented to create an iterative feedback loop in the development process

That's an interesting analysis. I hadn't thought of it that way before, simply because I wouldn't really value any other currency that way. I.e. I would not consider the growth in the ability to use euros in additional count

Someone could have the whole wallet... As I said, it is impossible to verify that that isn't the case. He could have taken a loan with the whole wallet as collateral. That isn't the same as claiming that Satoshi did that, but it&#

Lessons learned from sovereign debt crises: don't defend the peg. Let it float now, it will hurt more if you defend it all the way to insolvency. Devaluation is better than forced debt restructuring or full bankruptcy. Oh well, we&#x27

Not necessarily. I know it is slightly pedantic to point this out, but technical advances does not imply "free technical advances". e.g. you may increase productivity without increases in wages but not increase profits if the tec
