  • The problem is not that its impossible to establish trust in an electronic voting system. A qualified individual with the necessary knowledge in formal verification, cryptography, and computer science (maybe I am missing a field or two here) might be able to audit a system and verify that it adheres to certain standards and criteria.

    But I cannot do that, the average adult certainly cannot, and the bottom 5% percentile (of whatever criterion/metric might be applicable here) is so far removed from the problem that they are probably already having trouble operating such a machine.

    We were able to organize our own elections in elementary school to elect class representatives, and every kid understood how they work, and was able to observe the election process themselves, establishing trust in the system. If I have any doubts if my vote is going to be counted correctly in an election, I can go to my polling station and monitor the election as an independent observer or join the election board and do the counting myself. Every citizen eligible to vote has all the necessary tools available, both in terms of access to the polling station and counting of the ballots (which is public), and in terms of mental capacity and required prior knowledge. (Well, the last two points at least apply to a large majority of voters). I don’t need to trust the local government or dubious “experts”. The public’s ability to establish trust in the election system is essential in a democracy, and establishing trust cannot be delegated.


  • We had computers in elementary school. Around 3 or 4, they were standing in a corner of the classroom. I think my teachers husband just brought them in after his workplace decommissioned them. When you finished a task early, you were sometimes allowed to play around on them. I remember Paint, playing Pinball and Solitaire, and just clicking around/discovering the Windows UI. This was around the year 2000, we had no Internet, the computers were running Windows 95/98. I am not sure if we used them for any class-related activities. WordPad was installed, but no other Office stuff, I believe.

    I am glad that I grew up when computers were still understandable. Nowadays, kids get iPads, which teach them to be obedient consumers, but they will learn nothing about computers themselves. Too many layers of abstractions, all intended to obscure the underlying technology, and lock down the devices.

    Children have a natural desire to explore, which is completely wasted with modern devices. Let them open Paint.exe with Notepad and see what happens!






  • I use syncthing to sync almost everything across my computer, laptop (occasional usage), server (RAID1), old laptop (powered up once every month or so), and a few other devices (that only get a small subset of my data, though). On the computer, laptop, and server, I have btrfs snapshots (snapper). Overall, this works very well, I always have 4+ copies of my data in 2+ geographical locations.








  • I just compared the footage from various points in time. The flap positions for T+00:48:12 (pre-entry) and T+01:05:41 are almost the same, then it rotates about its rotation axis until T+01:05:44, but suddenly it starts to rotate about ANOTHER axis, and at T+01:05:47, its at a completely new angle. I think T+01:05:44 is the point where the flap finally breaks (after touchdown, but before splashdown).

    I think we have seen motion as fast as the one at T+01:04:22, but the subsequent bounce is surprisingly strong. I still think that the flap was still under some control at that point.

    I heard rumors on reddit that SpaceX deliberately removed a single tile on this flap for testing purposes, but I could not find any reliable confirmation for this. They deliberately removed tiles on the engine skirt, though.


  • I expect the flap on the opposite side of the ship experienced a similar level of destruction. Well, that depends on whether the damage occurred because of a general loss of structural integrity because of excessive heating, or if specific localized damage on that flap allowed plasma to penetrate the heat shield, resulting in the damage that we observed. So, general structural failure vs. random damage at that location cascading into a hole in the flap.

    Anyways, I am pretty sure that the complete loss of control authority on one of the flaps would be catastrophic. But the movement that we observed seemed pretty deliberate and consistent to what we saw during the suborbital test flights. Especially the unfolding of the flap at the T+01:05:42 mark is EXACTLY what we saw during the high-altitude flights, e.g., see SN8 @ T+6:33 or SN9 @ T+6:18. The forward flaps are folded back at first, and then rotate into a position perpendicular to the surface of Starship. The movement (for IFT-4) is precise, consistent with previous flights, and stops abruptly in the correct position.
