  • Scientists grow ‘lost tree’ mentioned in Bible using mysterious ancient seed

  • Articles like this really float my boat! It reminds me a bit of the discovery of the Wollemi Pine in Australia.

  • In Silicon Valley, a Rogue Plan to Alter the Climate | Some restless entrepreneurs are releasing pollutants in the sky to try to cool the planet.

  • One problem I have with this idea is that the cooling profile from releasing sulphates into the atmosphere looks very different from the greenhouse gas warming profile. For example, the latter has a more pronounced effect at higher latitudes, since GHG are insulators. The arctic is getting hit harder than the tropics. The former, I would expect, would affect the places in the world that get the most sun, since it is effectively a solar filter. So, the lower latitudes, in other words.

    If we have a baseline scenario A of what would have happened without the GHGs and B with what is currently happening, this would make for a scenario C that is neither of the others. I would submit that C would likely be as far from A as B is. Yes, you might get global warming under control in an accountant-looking-at-only-the-bottom-line sort of way, but this would still represent a massive climate change into uncharted territory. Would scenario C still be preferable to B is the question I guess?

  • People still working in IT, thoughts on IPv6?

    Jump

  • When I was first looking into IPv6, people were talking about how you can self-assign an address by simply wrapping an IPv6 address around your MAC address. But that practice seems to have fallen out of favour, and I'm guessing the reason is, as you say, the whole privacy thing? There's a lot of pushback these days against any tech that makes it easier to fingerprint your connection.

  • Off by one solitude

    Jump

  • This could be why Obiwan wound up a hermit? (Programmers of my generation at least talk about "Obiwan errors" because his name sounds like "off-by-one".)

  • If there was any object in your life that was cursed, what would it be?

    Jump

  • Was it red by any chance? The only red car I have ever owned got rear-ended 3 times.

  • If there was any object in your life that was cursed, what would it be?

    Jump

  • Yeah. My wife is always wanting to go on a cruise and I'm having none of it.

    One thing I will add regarding the nature of this curse is that it only manifests when I am the sole occupant of the bedroom. For example, I used to share a bedroom with my older sister, but within a week of her moving out and rejoicing at having the whole place to myself, the ceiling opened up.

    So I suppose I would be safe on the ship as long as my wife is there with me? In our current home, she was my sole protection, but has recently taken to sleeping on the basement cot due to hot flashes. This leaves me staring nervously at the ceiling. It's now or never, curse!

  • If there was any object in your life that was cursed, what would it be?

    Jump

  • Every place I live, there will be this incident when a torrential deluge of water breaks through the ceiling of my bedroom in the middle of the night.

    So it's not the bedroom itself that is cursed, since it is a different room each time. And the causes have varied also. The cursed object, therefore, must either be me or something in my possession I have kept around since childhood? Hmm…

  • What things from the 2020s do you think will age horribly?

    Jump

  • Ah fair enough. I guess I only learned about it in the 2020s when I read some expose on it and it made me throw up a little bit in my mouth.

  • What things from the 2020s do you think will age horribly?

    Jump

  • Fast fashion. At least I hope it does? It's such a wasteful abomination that we don't need right now.

  • Music industry’s 1990s hard drives, like all HDDs, are dying

  • Something to be said for the wfh movement too.

  • I suppose the regolith itself could be used as a heat sink. I don't know what its thermal properties are like?

    But yeah, I imagine heat dissipation is a limiting factor. Everything I've read suggests the 1st gen reactors will put out something on the order of 10s of kilowatts, so rather modest by nuclear standards but still plenty for a nascent Moon base I imagine?

  • The trouble with solar on the moon is that the day-night cycle is a month long. You have to figure out what to do during the 2 Earth weeks worth of night.

    I suppose with a polar base, you could have several solar farms strategically placed so that at least one of them is operational at any given time, but that's a lot of infrastructure and this is early days.

  • Music industry’s 1990s hard drives, like all HDDs, are dying

    Jump

  • I thought I read somewhere that when they were making one of the Toy Story movies, there was some catastrophic data loss that nearly tanked the whole production. But then one of the animators came back from maternity and said wait, I think I have most of it synced to my home server? And the next thing you know, John Lasseter himself is barrelling down the highway to her place and it turned out yeah, she did have it.

  • Cool! I can see how optical media could, in theory, be very long-lasting as long as you don't use materials that oxidize or otherwise degrade over time.

  • Well I guess I'm picturing DNA encoding like a RAID billion in terms of redundancy, so with some checksumming, you ought be able to sort out any mutations? But I'm no geneticist.

    Jump

  • That's why I back up my data on stone tablets in Cunieform.

    Seriously though, if you wanted data to last for centuries, what would be your best bet? Would it be some sort of 3D-printed mechanical storage? At least plastics are generally not biodegradable, though they are photodegradable, so I guess you'd want to stick your archive in a dry cave somewhere?

    Or what about this idea of encoding the data in the DNA of some microbe and cutting it loose? What could possibly go wrong?

  • Despite tech-savvy reputation, Gen Z falls behind in keyboard typing skills

    Jump

  • You know, I'm not actually quite sure what I'm doing, but I can tell you I am not looking at the keyboard. I suppose it's similar to how I play violin? I don't look at where my hand is but it shifts to different positions depending on what makes the most sense for the pattern I'm trying to play, and yes, a different position does imply a different fingering to reach the same notes.

    When learning to program, I initially tried to follow the touch typing guidelines, but they say that you should use the right pinky to reach every key towards the upper right end of the keyboard, which gets old fast given how frequently you need to access them. And just as with music, there are patterns. In programming, you may frequently need to type {}, :=, or even something like \{\}, and flailing around with the pinky is a good way to give yourself carpal tunnel. So your right hand learns to shift to hit those keys using a combination of fingers.

  • Despite tech-savvy reputation, Gen Z falls behind in keyboard typing skills

    Jump

  • As a Gen X, I think my typing speed peaked around late high school/early university? I tried to teach myself touch typing and got moderately proficient. Then I got into programming where you need to reach all of those punctuation marks. So my right hand has drifted further to the right over the years, which is better for code but suboptimal for regular text.

    One thing that's really tanked for me though is writing in cursive. I used to be able to take notes in class as fast as the prof could speak. Now I can scarcely sign my own name.

  • I am genuinely impressed that this has happened. Wow.
