md_··on Session Encrypted Messenger
Why?
md_··on Session Encrypted Messenger
I sort of understand people feeling like Signal/Mobilecoin is a get-rich-quick scam (though I really don't think it is), but I don't understand why, beyond the ickiness if that were the case, it actually matters.

Does it somehow reduce the effectiveness of Signal Messenger?

The argument against Signal here seems to rest on the weakest foundation. As I understand it, it's something like:

- This could be a get-rich cryptocurrency scheme. We don't have any evidence for it, but you can assume the worst.

- The project embarking on this scheme shows they don't have users' best interests at heart.

- If they don't have users' best interests at heart, how can I trust any of their other decisions?

This is not an argument I'd want to hang my hat on.

md_··on Tell HN: Amplitude (YC W12) just went public – AMA
Can, I guess. That’s generally L8 income; it’d be pretty unusually to make it to that level in seven years.

FAANG pays well, but if you check what I’m saying against Levels.fyi, that’s a pretty exceptional situation for someone with that little experience.

md_··on Klimaticket: All public transport in Austria with a single ticket for 1095 EUR/y
Agreed. Many consumers will still pay-as-you-go. I fail to see the problem.

I mean, yes, but that's like saying "all you can eat" buffets are unfair.

The only "fix" would be to never offer fixed-rate pricing.

It's a strange complaint, to me.

md_··on Malloc (YC S21) takes on mobile spyware
> The rising threat of spyware has prompted both Apple and Google to introduce indicators when a device’s microphone or camera are used. But some of the more elusive and more capable spyware — the spyware typically used by governments and nation states — can slip past the hardened defenses built into iOS and Android.

> That’s where Malloc says Antistalker comes in. Malloc’s co-founders Maria Terzi, Artemis Kontou and Liza Charalambous built the app around a machine learning (ML) model, which allows the app to detect and block device activity that could be construed as spyware recording or sending data.

That's a bit of a non sequitur, right?

If sophisticated malware is bypassing the OS-level "open mic" warning, that's presumably because it's bypassed the OS security model. As such, it should just as easily be able to avoid detection or simply disable any other detection mechanism, ML-driven or otherwise.

(If the issue is sophisticated malware that does not involve privilege escalation, e.g. by executing code inside the sandbox of a trusted app, I could see how an improved detection approach would help, but e.g. NSO and similar tend to use sandbox escapes + privesc, AFAIK.)

md_··on Something weird is happening on Facebook
I’m confused. The premise of this post seems to be that this is some malicious attempt to deduce basic geographic data on Facebook users. But doesn’t Facebook let you target ads based on such data already?

Why would I not just pay Facebook directly for such targeting?

md_··on Microsoft ruined passwords, now aims for a passwordless future
Oh, for sure that‘s true (with respect to telling employees “use these devices or you’re fired”). But I thought we were talking about the corporate relationship with society and the company’s users/customers.

In that broader context, I’m surprised that so many folks in this thread are arguing, essentially, that companies have a strong incentive to push (potentially needless, or costly from a privacy-perspective[1]) features on their users.

Historically, my feeling—-and I think that of many in the security industry—-was that the market does not reward pushing security, especially not security that customers can’t see; as a result, there’s some chunk of security theater, but real security features are often under-rewarded.

shrug

[1] To be clear, I disagree that most of these things have a severe privacy cost, hence my point that FIDO allows strong pseudonymity.

Authoritarian, or utilitarian?
md_··on Microsoft ruined passwords, now aims for a passwordless future
Eh. They don’t have a big incentive to, right?

It’s a risk, and I believe the batch attestation was controversial as a result. But the use cases are compelling.

md_··on Microsoft ruined passwords, now aims for a passwordless future
There's a concept of "batch attestation", by which the manufacturer builds in a key that attests to a batch (with a minimum batch size, to avoid identifying a single USB key--either 10k or 100k but I forget offhand which).

This is (AFAICT) intended to be used by, say, an enterprise who wants to restrict their employees to some trusted brand, but some banks and similar have also used it.

This is somewhat discouraged and annoying. In general, most places you can use a "self-signed" authenticator, which could be software and nobody would know.

md_··on Microsoft ruined passwords, now aims for a passwordless future
There's nothing that stands in the way of anyone implementing a software FIDO2 key (though some RPs can reject self-signed attestation certs if they want to, but it's not common AFAIK).

See https://github.blog/2017-07-20-soft-u2f/ for an example.

md_··on Microsoft ruined passwords, now aims for a passwordless future
To restate, I think your argument is that by making authn more complex, standards like WebAuthn will push towards "Identity as a Service" platforms like Firebase, Okta, etc, and that this concentrates power in the hands of those providers.

To an extent I think this is a fair argument, but it strikes me as somewhat of a Luddite one as well: yes, the better technology is also more complex, but most of the time users are simply more secure by developers choosing IaaS providers!

At the limit, you could argue against developer guidelines to use SSL or salted password storage, because those are "complex" and "encourage adoption of common providers." I don't think these security mechanisms are significant drivers of tech consolidation, and of all the things to complain about, the payoff for users--increased security--is hard to oppose!

md_··on Microsoft ruined passwords, now aims for a passwordless future
Seriously?

Please, explain to me how an arbitrary number of RPs can collude to link a FIDO2 identity.

md_··on Microsoft ruined passwords, now aims for a passwordless future
How is this not free choice? Are you saying Microsoft shouldn't be able to impose mandates to use their online service?

Genuinely curious.

md_··on Microsoft ruined passwords, now aims for a passwordless future
This is a strange argument, to me. I don't have any devices made by Microsoft, and have not for years. And I'm lazy and disinclined towards "linux on the desktop" neckbeardism. ;)
md_··on Microsoft ruined passwords, now aims for a passwordless future
Compliant FIDO2 keys guarantee unlinkability even against colluding relying parties. See https://fidoalliance.org/specs/fido-v2.0-rd-20180702/fido-se..., specifically "security goal 4", and the unique authentication keys requirement.
md_··on Microsoft ruined passwords, now aims for a passwordless future
Sure, but you're choosing their product, right?

Like, the same argument would suggest that "Who is Microsoft to say I need 256M of RAM to run Windows? If I want to run it on 128M, I should be allowed to do that!"

md_··on Microsoft ruined passwords, now aims for a passwordless future
> Also, that $10 security key is just a step away from being your national ID card. That's how bank logins work here. No passwords allowed.

Er, wouldn't that be a good thing? Identities cannot be linked to the same physical FIDO key across multiple relying parties, so what's the concern?

md_··on Microsoft ruined passwords, now aims for a passwordless future
The argument that Microsoft is somehow to blame for wanting you to either give them your phone number or buy a $10 security key before giving you access to their free online email and services is...weird?

Like, it's pretty normal for such services to demand phone numbers. Like Signal does.

If you don't like it, you can use something else? I fail to see what the big deal is here.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
Well, this also has easy alternatives: the OSHA rules allow testing as an alternative. They do not mandate vaccination.

To your other point, the vaccines do reduce transmission, as far as I can tell (e.g. https://www.gavi.org/vaccineswork/mounting-evidence-suggests...).

Now, to be perfectly serious, I do think that any efforts at compulsory--or, as in this case, incentivized, since testing remains an alternative--medical measures exist in a tension between the utilitarian and the libertarian point of view. We should certainly be cautious about mandating any medical procedure, and do our best to preserve alternatives (like testing, or mask wearing, or by limiting mandates to as narrow a scenario as necessary).

But I don't think the debate is helped by getting the facts wrong.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
The parent is me. :)

I think we agree that the debate is, as is, not very good. I might be making it worse by highlighting the least productive comments instead of engaging more selectively with the actually constructive ones, but, well...this is the Internet, right? :)

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
> why isn't Covid antibody testing a suitable substitute for vaccination?

As I noted elsewhere, in many jurisdictions it is, as is testing.

In fact, as the very article upon which you are commenting notes, under the new OSHA rules those who do not want to get vaccinated can simply take a test once a week instead!

I admit, some mornings I have a bit of dry mouth, but after my morning coffee I always have enough spit to hock a loogie into a cup. For science and the greater good.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
> I'm not sure how you arrived here from my comment. If I was willing to dox myself you'd see that I have probably taken more risks for 'the greater good'™ than you or even most folks on this site. But those days are over, and this whole situation is setting off all of my finely tuned alarm bells.

Thank you for your service.

In comparison, it seems to me the least I can do is get vaccinated, which is a tiny risk compared to the great deeds you have done.

You've inspired me, sir.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
I guess I'm just willing to live dangerously. Lots of folks are just too coddled and unwilling to take a risk, even for the greater good.

Back in the good old days, we were really willing to take risks--to cross oceans, even, as the op wrote--to do new things that could benefit our fellow human beings. Now it's all about "Oh no, this is a novel therapy that might infinitesimally increase my personal risk".

Really kind of sad.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
I don't see the necessary nuance for this debate to be meaningful. As a case in point: the OSHA regulations are for vaccination _or_ weekly testing.

There's probably a reasonable debate to be had about requiring people to disclose vaccination status (but, again, significant precedent)--but I do think the hysterical reactions sound a bit funny when viewed as a reaction to being forced to spit into a cup once a week.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
> Inevitable outcome in a society that is terrified of everything.

I agree. Lots of folks afraid to take a shot that's been well-studied and given to millions and is, in all probability, quite safe. ;)

I chalk it up to the youth, who are selfish and only able to think about themselves and their Friendster ranks and how many YouTubes they have on the FaceSpace.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
In the US, all 50 states have some type of mandatory vaccination for public schools (https://en.wikipedia.org/wiki/Vaccination_policy_in_the_Unit...). Most, but not all, allow religious or similar exemptions; some (including California) only allow medical exemptions.

I think your point--which is spot-on--is that a lot of the outraged reactions appear to be from people who are unaware (or unwilling to acknowledge) the very long history of compulsory vaccination (and who probably had such vaccines themselves as children).

That's not to say that any mandatory medical intervention shouldn't be treated with serious consideration, but the unwillingness to acknowledge precedent is bizarre and, I suspect, to some degree dishonest.

md_··on OSHA to require employers with 100 employees vaccinate or test workforce
I'm not and I have not heard that. Maybe they're taking horse dewormer. ;)
md_··on OSHA to require employers with 100 employees vaccinate or test workforce
It would probably save lives _and_ lower the cost of healthcare. This is why many employers already offer free on-site "influence" (heh) shots for employees: it makes good business sense.

I'm never sure how to take objections like yours, because there are certainly a few different things to discuss. Is your objection to the government's role in this (such that you'd be fine with private employers enforcing whatever mandates they wish)? Or are you objecting to the mandatory vaccination (in which case, what do you have against spitting into a vial once a week)?

Or are you more of a technocrat, concerned that the ROI (in terms of, say, QUALYs, as economists like to put it) gained through these policies isn't worth the cost?

All strike me as viable arguments, but it's always hard to tell which one is being put forward.
