jojoo | 3 years ago | on: Ask HN: How can I learn Imperial system I using the metric system my whole life?

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.

> It’s possible Chris is buying SEO and marketing, but given his self-described anti-corporate anarchism, I sort of doubt it.

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.

jojoo | 3 years ago | on: Japan tested a giant turbine that generates electricity using deep ocean current

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.

> Or, hear me out, devise a concrete that reacted with atmospheric co2 to produce something more benign. That way it changes from an emitter to being a passive remover

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...

That sounds like a tree to me...

jojoo | 5 years ago | on: Apple Doubles the Price of RAM Upgrade on Entry-Level 13-Inch MacBook Pro

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.

jojoo | 5 years ago | on: Elfeed with Tiny Tiny RSS

ACK.

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.

> On Android, OSMAnd is really good and there's also Maps.me.

Imo if you're a outdoor user on Android you should try out Locus Maps. I've used them with the downloads from openandromaps. Imo no other program comes close in terms of capabilities.

Palm really had the PIM suite down. A lot of other parts of WebOS were great, too.

Too bad the hardware was so mediocre.

jojoo | 6 years ago | on: Climate Change Is Killing Alpine Skiing as We Know It

Living next to a low elevation resort this makes me quite sad.

Climate Change will also impact other snow sports:

The future of backcountry skiing (at least in the alps) will be to drive up a mountain pass, get on a E-Mountainbike, drive up ~300m of elevation and then begin skinning.

Nordic skiing (where you need road access and a lot of flat-ish surface) will only be possible in a few quite elevated valleys without much sun.

Not really, because Glue is quite specific. And just because Glue X can be substituted with glue Y if you glue A and B together, doesn't mean Y is a good glue to bond A and C

jojoo | 6 years ago | on: The “mail is hard” myth

> A mail server is hard.

yeah, but compared with other services like WWW mail is IMO harder. You deal with two main Protocols and a lot of software. While mail takes 11 components in your tutorial, you'd get a website in 4. And some parts are hard to debug. I have very little means to debug why my mail wasn't delivered to my bosses gmail.

jojoo | 6 years ago | on: The “mail is hard” myth

I've been running a mailserver for ~15 Years.

I found it to be very time consuming and complicated, mainly because of the trouble of outgoing mail.

jojoo | 6 years ago | on: Installing Debian Linux 2.0 (1998)

> you were going to buy a collection of Linux distributions + the Sunsite archive on a 5-cd set that was released quarterly and available at computer stores.

I ordered debian potato (debian 2.2 / August 2000) as CD Sets via a german book store. Came with an OKish book. I distinctly remember that the SuSe book was better and i was really glad when i got a old SuSe manual from someone who upgraded his machine and got a new manual along with the 10 CDs.

Great times.

jojoo | 6 years ago | on: Unison File Synchronizer

that was one of my biggest problems ~8 years ago. keeping the macports and the debian versions in sync was too tiresom, someday i just switched to rsync which worked well enough for my usecase.

jojoo | 6 years ago | on: Spina bifida: Keyhole surgery repairs baby spine in womb

> He’s lived a long and fulfilling life, a life I want my daughter to have.

I've only worked with three students with spina bifida in my career in special-ed but everyone of them was a positive-optimistic child with a lot of emotional intelligence. Everyone wants to befriend them because they are funny and kind.
