They may still train on it if you submit feedback or flag a safeguard. The terms are a bit fuzzy on this.

Inside the JS sandbox, not the browser's outer containment sandbox.

That blocks all sorts of abuse, but a targeted exploit would be delivered on a clean domain.

It would be chained with a separate 0day sandbox escape.

uBlock Origin won't help with this kind of targeted exploit, and Firefox has a much worse security track record.

Which browser has a better security track record?

eID PKIs have very little in common with the web PKI. There's a national root of trust with strong attestation. It's a very simple trust relationship. You already trust the respective government to issue IDs.

Plenty of European countries have an eID CAs and it works fine. The PKI part is a solved problem.

Doesn't even need ZKP, the CA can just issue an attestation.

Yes, if you're unable to be polite about it, just don't comment and/or email the moderators. Your comment would have been informative and well-received without the snark.

You were right to call out the other person for trivializing the risks of tick bites, just assume good faith and be kind.

TIL about Ticktogs. Thanks!

Be careful with the dismantling, if it's a used test, you will likely end up with DNA amplicon contamination which is extremely hard to get rid of.

HN has very specific rules for this: https://news.ycombinator.com/newsguidelines.html

You don't respond to them at all, flag the comment, and/or email the moderators.

Being snarky does not contribute to the discussion and gets your comments flagged.

Lucira did that, but IMO it's quite wasteful. LAMP reactions don't need much, so it's best to make a cheap reader like Metrix or Pluslife so the tests can be less expensive.

Antibiotics aren't free of risks to the patient either, including doxycycline. There's always a risk tradeoff.

There's also the more fundamental issue that Postgres - unlike something like Yugabyte - does not use a distributed consensus algorithm for writes and can lose committed writes during network partitions.

But of course, neither does Tailscale's weird DIY contraption.

And tick-borne encephalitis, in regions where that is endemic.

No need to be rude, though!

Ticks climb low vegetation (not just grass) and wait for a host to pass by ("questing").

If you're going to disagree with basic textbook biology knowledge, the burden of proof is on you.

CDC recommends prophylaxis only if the tick is engorged. In my country, guidelines do not recommend prophylaxis at all (for better or worse - personally, I would take a single doxycyclin dose for a >24h high-risk tick bite, Lyme is no joke).

However, guidelines universally recommend against testing ticks. For instance, IDSA says this:

> Knowing tick characteristics (ie, species, life stage, and an assessment of the degree of blood engorgement) is helpful for anticipatory guidance and in determining if antibiotic prophylaxis to prevent Lyme disease is appropriate [127]. Tick identification is available in most commercial laboratories and at some local health departments. Studies from the United States and Europe have shown that detecting B. burgdorferi sensu lato in Ixodes spp. ticks, however, poorly predicts either subsequent disease (0–12.4%) [126, 128–133] or asymptomatic seroconversion (0–4.7%) [126, 129, 130, 132, 134]. This is likely due to a variety of factors that influence the likelihood of transmission and the observation that most Ixodes spp. ticks discovered by patients have been attached for <48 hours [61, 62, 135].

(https://www.idsociety.org/practice-guideline/lyme-disease/)

The point is that the test is likely not useful to reliably inform any sort of prophylactic treatment, especially if the risk of transmission is high enough to warrant prophylactic treatment in the first place, in which case the PEP is indicated regardless of the tick test.

Sure, it modifies the prior probabilities, but what's the clinical significance of that?

> But you would know whether you needed to even book an appointment.

Only if the test is sufficiently accurate to rule out transmission. Even molecular tests can't reliably predict that.

Yes, but this test cannot diagnose Lyme in humans.
