Because flare fittings are a concession to make install cheaper, not better. R410a and other similar refrigerants are very high pressure, and the fittings undergo significant thermal cycles. Flared copper tube is a bad design choice. IMO, g

I always like the inverse of this, which is that if you calculate that less than 68% is in the first standard deviation, you can guess that the data isn’t normally distributed. It’s really a heuristic on where to start with analysis, though

No, i mean, I don't expect anyone to allocate anything to my non-viable projects. I expect to allocate my own money to them like I always do, but, I'll be more able to achieve my goals. If things pan out, maybe these things could

I'll just add that I have so much more "non economically viable" work than I'll ever be able to do. I'd love machines that could write code for me to do tasks that I'll never be able to afford to invest in othe

I agree the effects are asymmetric. an important consideration behind all of this is that there is very little that government or power can do to extend the lives of humans, and very much they can do to shorten them. When we thing of "

I'm in Boulder, too, and you can't ignore the "housing stock" problem here. There are a lot of crap houses in boulder that really need to be demolished. A late 90s house on my street sold in 1 day over asking, while an &

I do not think the animal meat consumption is the reason? Animal origin, not animal meat vector. This isn't a debate about veganism and moralism.

I recently got quoted $17k for 2 zone mini split. I bought the tools, instructions, and watched youtube and spent $4500 total. At that savings, I don't need a warranty. I can just buy and install another system if it fails.

Also - is this going to be R410a, or R32?

There appears to be a disconnect between "productivity" and "value" in the startup world, or maybe put another way, a lot of hard engineering work tackling "easy" problems. It seems like everyone assumes that &

I think the whole fast vs slow thinking is also a bit tied up with kind of like "raw intelligence" vs "trained skill". I think there are some people who are really really smart and fast thinkers, and some people who are

The thing about these scales is that they are actually numeric. (And not real good, but that’s another story.) I’m an INTP, but really close to the middle on the I and the N. It changes things relative to some coworkers who are much more I

China is a currency manipulator, human rights abuser, and a non-democratic state. that is a country we have done business with, and looked past, but the US can't be "friends" with terms like that. The relentless anti china pr

AND!!! compared to a similar sized car with an anemic little 4 cylinder, the leaf is much better to drive, IMO. (I have a 2020 model). Its not a mercedes, but the torque off the line is so much better.

It's just that to the HN audience, the spam sure seems unsophisticated. I can imagine being able to filter out most blogspam just by looking at the CSS. like, every blog spam review and restaurant site is so obviously bad it hurts. als

this is kinda true, but only if you say, "In the short term". In the long term, things are recursive - poor employee morale loses productivity and product quality suffers and customers leave and shareholders lose. And that is only

its really a perfect continuation of the Mark Twain, “I didn't have time to write a short letter, so I wrote a long one instead.” Really succinct fast code probably takes more time than verbose, slow code.

Thank you. Yeah, the maslow is ingenious. I love the idea and the approach, though it doesn't do well with odd shapes or fixtures. I think of it more as a sheet cutter than a CNC router, just because it doesn't really have the abi

my personal criticism is that that the article's premise is that Stanford "May" ask someone to do something. The outlet has published a letter to stanford seeking corrective action in line with their politics. In general, I a

lol, you are of course correct. It seems they are owned by the Center for Media and Democracy, which looks pretty neutral, but it is of course hard to tell.

this is good advice. I've done it with everything from weird machine tools (tool and cutter grinder) to woodworking tools to snowboards to guitars. if you don't treat big purchases as permanent, you'd be amazed at what money
