Most sci-fi stories involving time travel involve a mechanism that's incredibly rare and/or difficult to operate.

What if complete plans for a working time machine, including its power source, were published anonymously on the web, in a decentralized fashion? (Impossible to identify who published it, or from where, and thus making it impossible to go back and prevent the publication.) What if anybody could build their own, using commonly available parts and tools?

It's only April and my PV panels have already hit a peak output over 10% over their rated capacity (yesterday). The power graph from today clearly shows the jump around 9am when the sun is finally in front of the house. The house faces SSW so the panels aren't getting direct illumination from sunrise, though they're still producing a tiny bit of power then.

Tfw you're midway thru the red-eye return flight to Europe from the US, and you're going to swap the US SIM card out of your phone, and you push a paperclip into the SIMcard holder's eject hole, and it pops out suddenly and you see the microSD and SIM cards go flying into the darkness.

I think we're focused on the wrong thing when we look at what tech works for a company like Amazon or Facebook or Netflix.

We should be looking at what tech works when you don't have a small army of staff engineers optimizing it. I want to know what I can scale without paying someone a half million dollar salary to do it.

There should be more case studies on things that don't have a billion-dollar company propping them up, humming along quietly on a cheap-ass VPS somewhere.

@collinsworth what Amazon and Google won't tell you is they run all their own infrastructure on #OpenLDAP. And it doesn't need armies of engineers to optimize because it already scales perfectly linearly across arbitrarily many CPUs without any tuning.

followed a thread on bsky infra to this fascinating sentence in wikipedia: "...replacing Cassandra's Java, and the Seastar asynchronous programming library replacing classic Linux programming techniques such as threads, shared memory and mapped files."

@dvd funny, since OpenLDAP already does set operations on 64bit index hashes, and doesn't even have the overhead of an rwlock. I suspect we can blow away their performance numbers in a fraction of the CPU time.

But hey, I guess everyone has to reinvent the wheel for themselves these days.

As you know, I go to a ton of #carmeets. Well, #Cybertrucks have started showing up to a couple of morning meets the past two weekends.

And I noticed something interesting: car people ignored them. Nobody stopped their conversation to look. Nobody got on their knees to take photos. Nobody got their phones out to make reels. They just glanced at the truck, and went right back to talking with their pals. Absolutely zero interest.

It’s fascinating because the weirdest-looking, ostensibly most technologically interesting vehicle to have come out in decades shows up, and car enthusiasts treat it like it were a Kia Sedona. Every reviewer of the Cybertruck says they constantly get stopped by people wherever they go—well, apparently, this does not happen at car gatherings.

And it’s not about EVs, either. Bring a Rimac Nevera, and I guarantee you’ll get a crowd forming around your car. It’s the Cybertruck in particular.

@drahardja there's just nothing cool in the 21st century about a vehicle that looks like it was modeled on a 3D graphics system from the 1970s.

Like BerkeleyDB, and unlike most other key/value stores around today, is more than just a simple K/V store. Its support for multiple tables, and txns spanning multiple tables, lets you implement other features like 2ndary indexing, metadata storage, etc., that ordinary K/V stores just can't do. Here, describes how they designed their data model on top of LMDB https://docs.harperdb.io/docs/technical-details/reference/storage-algorithm

Amazing to think that this was already a "retro" computer game even when we played it in school in 1984!

I don't think we knew it was THAT old. With contemporary IT generations more likely to be measured in months than years, a 12 YEAR OLD computer game would have felt like communing with the ancestors... 👴

@davidgerard what side channels? Sure if you go to an exchange and deposit xmr and withdraw some equivalent sum of anything else it's pretty obvious. But that's a property of centralised exchanges, not Monero itself.

we looked at other ActivityPub clients we might use, but everything is obsolete or based on web technologies except Tokodon, so here we are still trying to use it

kudos to the KDE people and all, it just has a few small friction things for us. we're going to keep trying to get used to it.

Star Trek question, how come the Ferengi are so obsessed with wealth, if the tech exists to just replicate anything including money 🤔

#StarTrek

hyc,
@hyc@mastodon.social avatar

@bazkie I've read other science fiction that illustrates the point that nothing is zero cost, there is always an energy cost to everything, and the amount of energy any particular entity can access is always finite.

Running a replicator costs energy. The mass of the thing you're replicating requires energy. Even if you can harness the power of an entire star, there's limits to how much you can replicate. Anything that is limited is scarce, and scarcity = high value, separates wealth / poverty.

@rain @ChasMusic @carol it's actually not so difficult these days, all the common gotchas have been seen and done. There's a large initial effort to put the infrastructure into place (depends, gitian, guix, whatever) but once it's set up it's no harder than typing "make".
