    I remember many years ago New Scientist magazine did a review study of many different alternative medicine techniques and found that the only benefits they provided were placebo effect.

    Except acupuncture. That was the only one with an effect greater than placebo.

    It was hardly ever used in WiFi. Two modulation schemes were available in the original WiFi spec, FHSS and DSSS. DSSS was always preferred over FHSS and in practice FHSS was hardly used and eventually obsoleted a decade ago. It was never “the basis” of WiFi as claimed in the meme - that’s simply incorrect.

    Don’t get me wrong. FHSS is cool and it’s a great achievement. It just has basically no bearing on WiFi and absolutely no relationship to GPS.







  • It’s also a fallacy that rust code is memory safe. I audited a couple of large rust projects and found that they both had tens of unsafe constructs. I presume other projects are similar.

    You can’t use “unsafe” and then claim that your program’s memory safe. It may be “somewhat safe-ish” but claiming that your code is safe because you carefully reviewed your unsafe sections leaves you on the same shaky ground as c++, where they also claim that they carefully review their code.


  • But also, only 30% of breaches are caused by memory errors. That’s because most CVEs related to memory errors don’t result in as many real life breaches as non memory error related ones. Presumably because this class of vulnerabilities is harder to exploit than ones due to logic errors.

    So assuming you could reduce the number of memory error related exploits to zero by avoiding c++, you’d only reduce exploits by 30%. That’s still a great result but not anything like the 70% implied here.




  • Kaliningrad’s fairly strategically useless to them now that every surrounding country’s NATO though. The Suwałki Gap between Kaliningrad and Belarus used to be pivotal in potentially re-taking control of Lithuania, Latvia and Estonia. It would have been very difficult for NATO defend them if Russia took the gap. But now those countries are protected by NATO countries all around so Kaliningrad’s a lot less useful strategically. Not to mention that there’s a strong Kaliningrad independence movement so they’re struggling to control it internally as well.
