  • There’s an already-extant ground-based vessel navigation system, Loran-C, though I’m sure that it’s possible to improve on it and I have no idea how much of the receiver hardware is still out there.

    https://en.wikipedia.org/wiki/Loran-C

    The introduction of civilian satellite navigation in the 1990s led to a rapid drop-off in Loran-C use. Discussions about the future of Loran-C began in the 1990s; several turn-off dates were announced and then cancelled. In 2010, the US and Canadian systems were shut down, along with Loran-C/CHAYKA stations that were shared with Russia.[2][3] Several other chains remained active; some were upgraded for continued use. At the end of 2015, navigation chains in most of Europe were turned off.[4] In December 2015 in the United States, there was also renewed discussion of funding an eLoran system,[5] and NIST offered to fund development of a microchip-sized eLoran receiver for distribution of timing signals.[6]

    The National Timing Resilience and Security Act of 2017, proposed resurrecting Loran as a backup for the United States in case of a GPS outage caused by space weather or attack.[7][8]



  • I’m sure not, but even without looking at any technical details, it will have at least a couple benefits:

    • First, it’s short range. GPS satellites are in geosynchronous orbit, which is a pretty high orbit. Wikipedia says about 22,000 miles away. For GPS, the jammer is going to be far closer than the legitimate signal.

    • Second, I’m guessing — though we’ll see — that this is going to be a civilian system, and I suppose that they could even try to mandate that militaries not use it. GPS was, from the beginning, a military system, and there are weapons being used in Ukraine that use it for guidance. Unless you’re solely out to be a dick — which isn’t impossible — probably not a lot of benefit to stomping on civilian-only frequencies.








  • Italy is using its Piracy Shield law to go after Google, with a court ordering the Internet giant to immediately begin poisoning its public DNS servers

    I don’t know why Italy is wasting time on this.

    Italy is not going to be able to force all public DNS servers out there to block things that they want blocked. Anyone using Google’s DNS servers is already going out of their way to use an alternate DNS and can probably plonk in another IP address if they want. It’s not as if Google has the only publicly-accessible DNS server out there.

    If Italy really and truly doesn’t want a DNS server that is doing this to be accessible in Italy, go after Italian network service providers, and instead of playing a never-ending game of whack-a-mole until they run into someone who just tells Italy to buzz off, just block it. Now, some portion of Italians are probably going to still get to DNS servers that ignore Italy’s views on things via VPNs unless Italy wants to ban those too, but it’d at least be more-effective than trying to go after every DNS server provider out there, which is definitely is going to leave DNS servers that don’t block sites accessible online.

    Frankly, I don’t even think that DNS-based censorship is very effective in the first place anyway, but if you’re going to do it, might as well at least do it as effectively as possible.


  • Vidoc posted on local job boards, like the one in Poland. But whoever was behind this operation figured out that it’s profitable to pose as Serbian, Polish, and other eastern European profiles

    I’d think that this could be pretty easily resolved by just having a real-life interview, at least for the final interview.

    It sounds like Vidoc is in Poland. Maybe it’s just me, but if I were being hired for an engineering position, I’d think that it’d be reasonable to be willing to travel to a final interview, and for the company to cover any costs.

    But, okay, say that it doesn’t make sense. Maybe the finances don’t work, maybe they want to hire from somewhere where it’s not practical for people to travel to their location. I’d think that it’d be possible to have an “interviewing company”. That company just obtains some office space, sets up videoconference conferencing rooms, and has their own trusted cameras and suchlike present.



  • Combating “Skynet”-level threats

    During the experiment, the professionals were faced with a typical national security threat: A foreign government interfering in an election in their country. They were then assigned to one of three scenarios: a control scenario, where the threat only involved human hackers; a scenario with light, “tactical” AI involvement, where hackers were assisted by AI; and a scenario with heavy levels of AI involvement, where participants were told that the threat was orchestrated by a “strategic” AI program.

    When confronted with a strategic AI-based threat — what Whyte calls a “Skynet”-level threat, referencing the “Terminator” movie franchise — the professionals tended to doubt their training and were hesitant to act. They were also more likely to ask for additional intelligence information compared with their colleagues in the other two groups, who generally responded to the situation according to their training.

    That’s a human-level (well, superhuman) AGI. I don’t think that we have a good handle on what the limitations or strengths would be. I’d try to gather as much information or thoughts from others as I could too.

    In the same vein, if someone gave me a scenario where they said “You’re facing a demonic necromancer. How do you counter them?” I’d probably be a lot less confident about how to act than if they said “you’re facing someone with a pistol”, because this is kind of out of the blue, and I don’t even really understand the nature of the threat. There’s no AI there, but it’s a novel scenario with a lot of unknowns, and it’s not as if I’ve read through histories of how people dealt with that or recommended doctrine for that. I don’t think that it’s the AI that’s so much the X factor here as it is the sheer degree of unknown factors that show up.


  • If you’ve already got a VR headset and you’re happy with it, I’m envious. But for the rest of us, it’s worth asking the question: just what is it going to take to get on board?

    Speaking for myself, if I can use a headset about as well as I do a regular display, that’ll do it for me. I’m less-interested in a gaming-specific peripheral, though that’d be nice frosting on the cake. If I can just carry a headset in a case and a display-less laptop, that’d probably be sufficient to get me onboard the HMD train.

    There are real benefits to that:

    • Privacy. My screen isn’t visible to anyone nearby.

    • Wider field of view possible.

    • No glare issues.

    • Potentially less power use, since one isn’t blasting light everywhere just to get a little into one’s eye.

    • Able to use in any orientation easily, like lying down.

    My experience so far has not led me to believe that this is near. I’ve found HMDs to be twitchy about the location relative to the eye, prone to blurriness if nudged a bit off. Blurriness around the edges. On my Royole Moon, fogging up is an issue, due to shields to eliminate light from bleeding in. Limited resolution. For some, inability to easily see the surrounding world. Limited refresh rates. Many headsets can’t really be used with headphones, which is okay, as long as you’re fine with the headphones that come with the headset. [EDIT: As someone else pointed out, setup time is a hassle as well. I want using one to be as trivial as it is today for me to open my wireless headphones case and throw the headphones on my head, with just the addition of a cable.]

    I don’t personally really care all that much about price, if the thing can serve as a competitive monitor replacement, since then it’s not just a toy.

    I’d also add that I think that there are some genres, like flight sims, where VR has legitimately succeeded. Like, compared to multiple-monitor rigs that some serious flight sim fans have set up, VR is pretty much better in all ways. No physical control panels and such, maybe, but they really want the wide FOV and ability to use the head/eye as an input device.

    I’m sure that there are probably some AR applications where you can find an AR headset making sense. Maybe stargazing or something.

    But what the article author seems to want is a transition to a world where basically all or a large chunk of new video games are VR-based. And yeah, that hasn’t happened.

    EDIT: Honestly, most of the games I find myself spending a lot of time playing aren’t even 3D in the first place. That’s not due to lack of hardware. I have a pretty maxed-out PC, can run them fine. It’s just not what I think is most-entertaining to do — many of the games that I find really deep and replayable are 2D, so I’m not playing the 3D games that I do have. If the games aren’t 3D, it’s hard to see how VR buys much.
