@midnightmagic @pwuille What kind of cleaner solution? Spam prevention with email's design is fundamentally hard. Hashcash would have likely failed due to botnets and Asics; Bitcoin Lightning didn't exist until very recently.

@Stinkie @jernej @TechConnectify Also, IIRC the removal of USB ports was purely due to supply chain issues and you could get them reinstalled later at the dealer once parts became available again.

@Stinkie @jernej @TechConnectify Yes, tactile controls I agree aren't worth the cost/weight reduction. But for things like battery heaters, I'm not going to second guess the engineers.

@TechConnectify Have you worked out how long it takes to heat up the motors compared to the battery pack? The motors have about 1/10th the mass of the battery packs, so I'd be surprised if it adds more than 15% to the warming time, even including losses.

Seems like it could be a good tradeoff to reduce weight and cost.

@jernej @TechConnectify A lot of that "cost cutting" is also weight savings, which matters a lot for already-heavy electric cars.

Luxor mined a block with four full-rbf replacements at once: https://web.archive.org/web/20221224215544/https://fullrbf.mempool.observer/

Two from my OTS calendars (including a $165 fee). And two others that I didn't create.

Great example of how legacy payment systems are totally busted: https://www.raspberrypi.com/verify/

Excellent video.

@ademan Yes.

The archive.org link has the raw hex of both transactions if you want to take a look.

Interesting! Foundry USA mined a full-rbf double-spend, with a few minutes between tx #1 and tx #2: https://web.archive.org/web/20221221022035/https://fullrbf.mempool.observer/

My best guess is this has something to do with unconfirmed inputs. My stock v24.0 node saw both tx #1 and tx #2 at the same time initially, but rejected the latter for spending an unconfirmed input. Then a few minutes later, it accepted tx #2 once the input confirmed.

@nvk not working.

@nvk No sewage community?

You obviously haven't seen the septic tank pumping part of YouTube. Or the thriving community of plumbing blockage clearing videos. I'm sure they have conferences too. Shitty ones.

@ademan @silverpill @pwuille Thet could work too.

@silverpill @pwuille “transaction lookup can be expensive” just provide a merkle path from the confirmed tx to the block header.

@silverpill @pwuille Both. Though payments don't necessarily mean paying someone in particular: you can also sacrifice BTC to make a cryptographic identity expensive to obtain.

This is probably better than hash cash as it's easier to determine the value of the payment/sacrifice.

@pwuille I think the big problem we're going to see is that Mastodon has much worse protections against spam than Twitter does. That's not a problem yet. But it will be in the future. And dealing with it could destroy the ability of small instances like mine to federate with others.

If email didn't have big companies like Google pouring money into anti-spam, it'd probably be dead already.

Bitcoin can fix this by making spam costly. But the people behind Mastodon hate crypto currencies.
