My context for "learning" Imperial is solely based on measurements of length. I've "learned" it b/c i listen to a lot of US-Centric carpentry podcasts. I've just memorized 1 inch ~ 2.54 cm ; 3/8 inch ~ 1 cm. Most other fraction can be derived from those in the head. At least enough for following a carpentry podcast.
When i need more precision, i use an online converter or a ruler with an imperial and a metric scale. FWIW i only think in metric.
For educators i always suggest "The Diamond Age". In the last few years, AI has just catched up enough for non-tech people to take it serious.
I really liked the first half of Fall; Or Dodge in Hell. But it has been the only Stephenson book where i needed discipline not to get enough sleep, but to get through the second half.

I mean you never know. But i think there's another explaination: He is one of the most popular woodworkers ATM and he has published a lot of material, so it's only natural if his name comes up more than others.
I'm not good at nautics, but in my understanding currents slowly stop and later turn around. Most tide charts are more or less a sine wave, with different highs and lows.
So it's interesting how this 100kw was produced.
The article only says: "The business was able to generate roughly 100 kilowatts of steady electricity during demonstrations earlier this year."
So is this over a few days or just a few hours while peak flow? While currents change, their change is highly forseeable - unlike wind.
Currents are relatively unrelated to tides, and are fairly consistent over time (with some seasonal variation due to differences in hemispheric temperatures).
From [1], "the large scale prevailing winds drive major persistent ocean currents..." Keyword is persistent.
I imagine that's one goal of the project? I can't imagine that there hasn't been a shit ton of experiments with "deep" sea currents before this power experiment. I mean it's dead obvious and they wouldn't have ponied up the cash for this if ocean currents were all over the place.

Good propertyy. It would be even better if the material acted as a good insulator. And be re- or upcyclabe when we need to tear down the building. And while we're at it: it would be nice if the product would just grow...
Sadly the machines from the repairable / upgradable era are getting to the end of their lifespan; at least with normal MacOS and standart software.
I'm writingh this on a 2010 mbp on it's third battery, second ram upgrade and new-ish SSD and i'don't know if my next machine will hold up ~10 years when nothing is easily replacable.
Can you imagine a Windows based PC lasting half of that time?
Outside of the silky OS and tight Linux coupling, it has been a joy to buy computers (albeit at a premium) that last more than 2 years.
I still have a 2009 iMac that is perfectly fine for everything except iOS development (due to an Xcode OS minimum) and a 2015 MBP for that. While my new work 16 MBP is a performance beast compared to the 2015 MBP, I can certainly be productive and expect to be for years to come with my personal kit.
> Can you imagine a Windows based PC lasting half of that time?
Yes, my Thinkpad T420 still does. Don't compare consumer-grade $300 laptops/PCs to Apple hardware that costs $2,500+, please.
A modern Windows 10 is also still able to run applications written in 1999 and even earlier. Apple only supports the last 3 releases of macOS which puts the burden on the developers that often don't even support the applications anymore.
There are many reasons to dislike Windows(-based PCs) but your argument is very, very weak.
> Don't compare consumer-grade $300 laptops/PCs to Apple hardware that costs $2,500+, please.
If you're the type of person who doesn't put your hardware through a beating, I find that name-brand consumer PCs to be fairly durable. But like you said, they are obviously not as nice as Apple hardware.
Another thing about PCs is that you don't get forced obsolescence from Mac OS upgrades that stop supporting old hardware that is still usable, outside of having a weak gpu.
I have seen this happen so often. People who evidently don't use or haven't used a Windows based machine in the last 20 years complaining more than anybody else.
There are plenty of reasons to hate on Windows(-based machines) but what would they know.
Prior to Apple hardware, I loved my T42... definitely a strong machine on a great platform.
Maybe it is just small sample size, but my mil purchased an HP consumer laptop for ~$600 when I purchased my first MBP in 2010. Hers barely lasted 3 years for hardware and software reasons. My chugged on for 6 years. While the cost per year was similar... the utility was not.
I hope it is better, but during the 1990-2010 period when I ran Windows based systems they inevitably would come to a crawl after a year of use. I would have to completely rebuild them, reinstall the OS and all programs from scratch to return them to utility.
I honestly don't think I have ever done this with an Apple product.
Easily, if you plan your hardware purchases. My 2012 desktop PC is still doing great. Intel i7-3770, 16 GB RAM, SSD. I'm glad I haven't let myself be convinced by the popular opinions at the time that i5, 8GB RAM and HDD are totally fine and there's no reason to pay more.
The only component I've upgraded was a graphics card, but that's only because I play games on this PC. Otherwise, my old GTX680 would have still been fine.
My early 2011 15" Macbook Pro barely lasted 4 years before being bricked by a design flaw. These particular MBPs have ended up dying post-recall as well. Two out of the three that I know of in my social circle that got the recall fix died afterwards.
That 2011 MBP is easily the most short lived computer (and one of the more expensive) I have ever had, and I've had >2X more Windows computers than I have had Macs.
Having said that, I would still say that the 2012 15" MBPs were the pinnacle of MBPs -- for me --. I know that a lot more people prefer the 2015 MBPs, but thin and light is not tops on my priority list.
The 2011 issue is probably bad GPU, which affected entire industry for a while (2011 ThinkPads with discrete GPU had similar issues). A possible fix is to disable the discrete GPU and use only the integrated Intel: https://apple.stackexchange.com/questions/166876/macbook-pro...
It is definitely GPU + heat related, but disabling the GPU is an unacceptable solution. People paid top dollar for a Macbook Pro with a fast GPU, you don't tell them to write off the premium they paid for that feature by disabling it.
But here's what the real problem was. Apple pretended the problem didn't exist for a very long time.
There was a huge thread on the Apple Support site related to this issue that was literally hundreds of pages long that spanned over a year. People were resorting to baking their logic boards in an oven to fix the issue, albeit temporarily.
Many people eventually gave up and wrote off the hardware before Apple finally acknowledged the issue with a repair order. This happened to me. I had the logic board replaced once already while under AppleCare (and the issue came back a few months later, but there was no point in constantly having the logic board replaced with another having the same design flaw). Just before my Applecare lapsed, it died. I wasn't going to pay $500+CAD for another defective board.
I was lucky I kept my unit around long enough when the repair order (recall) was issued. It still ended up dying a while later.
Apple had many options to make their affected users whole. They make enough money that they could have replaced everyone's 2011 model with a 2012 model (even a refurb would have been OK) which had none of those issues. Had they done that, I'd probably still be a Mac user (using that very same 2012 model) right now.
In the end, that experience completely soured me from Apple.
It's amazing Nvidia got away with their scam GPUs and didn't go bankrupt from their intentional underreporting of GPU thermals / power consumption that led to the mess.
Considering I'm still playing the newest games on my ten year old LGA1366 setup, yes. Overclocked Xeon X5675, Nvidia 1070, 16GB RAM, and SSD. Currently playing the new Doom completely maxed out at 2560x1600.
> Can you imagine a Windows based PC lasting half of that time?
Yes? I built a ~$1500 PC in 2013 and still use it for non-work purposes. I did put Elementary OS on it though instead of Windows 10, and it's starting to show its age running some newer games but it works just fine.
I switched from google reader to feedly to newsboat. One cloud service less.
While i like the idea to be able to read my feeds from multiple computers, i don't actually need it. In fact, readig them on only one device gives me back (a little bit of) focus.
The main character being cast into diferent bodies over the course of the story making me contemplate what makes us the person we are and the final monologue at the end, reflecting on whether it is ethical to betray people even if it makes them happier. The value and importance of being honest and true to yourself, even if the truth is hard and hurts.
re-reads for me:
Diamond Age (4) (I'm an educator), Cryptonomicon (2), Baroc cycle (2)
However i plan to re-read Anathem in paralell with my second re-read of Russels A History of Western Philosophy. Really looking forward to this one.
