BjoernKW··on Immune response study explains why some people don't get Covid-19
Quite to the contrary, regular use of amphetamines impairs the immune response, which isn't all that surprising since chronic amphetamine consumption leads to increased stress levels.
BjoernKW··on What's the most radical book you've read?
Prometheus Rising, for certainly being rather radical and refreshing.

> Funny how with Germany's extensive paperwork bureaucracy where every little detail must be recorded and tracked, the healthcare workers couldn't catch this guy earlier.

It's precisely because of this extensive paper-based bureaucracy such things happen, not despite of it.

German bureaucracy is a complete and utter mess. By and large, it's a self-perpetuating end in itself that doesn't serve any purpose other than keeping itself (and the people and organisations involved in it) alive.

Which is more, due to the Germany aversion towards digitization and digital processes (with a misconceived notion of privacy commonly known as "data protection" in Germany often used as an excuse) the data recorded by those bureaucratic processes basically is stored in a gargantuan pile of paper nobody is able to make sense of.

BjoernKW··on Ask HN: What are your oldest "online" accounts still in use?
To this day, I still remember my ICQ number from back in the nineties. However, unfortunately the same doesn't apply to the password and I can't seem to be able to reset it.
BjoernKW··on Ask HN: What are your oldest "online" accounts still in use?
I suppose that'd be my Amazon account (mid to end nineties). Other than that, my Microsoft account, which used to be my Skype account from 2003 (IIRC).
BjoernKW··on Paul Alexander, ‘the man in the iron lung’, has died
N95 / FFP2 masks are sufficiently effective (if worn correctly) to reduce the likelihood of getting infected to the extent they effectively prevent infection on a personal level.

There's of course still a small chance of contracting COVID-19 in spite of wearing a mask, which is why for society at large masks only slowed down the spread at best. For the individual person by and large the probability for getting infected is negligible, though.

This precisely what those - quite heated - arguments (and pertinent studies) regarding masks being not effective at all were about: Masks are highly effective on a personal level; for preventing community spread their usefulness is limited.

> It is practically impossible to avoid catching covid in modern society.

For the average human going about an ordinary and active life that statement is quite true.

However, the person in question didn't lead an ordinary life. He was confined to a medical device and probably very rarely had in-person contact with random people. Besides, the people who met him personally all must have known about his condition.

Under such circumstances avoiding COVID-19 is actually pretty easy: Have everyone in the room wear high-quality face masks.

Even for the average person during the height of the pandemic, avoiding COVID-19 was still possible, but required significant effort (no lockdowns though, mind you): Basically, it meant wearing such a mask properly in public settings (and changing it at appropriate intervals) as well as frequent testing of everyone you were in touch with regularly.

BjoernKW··on Ask HN: What are the best eBook authoring tools today?
We used the Markdown plugin that comes bundled with IntelliJ IDEA alongside this Mermaid plugin for diagrams: https://plugins.jetbrains.com/plugin/20146-mermaid

As for the code samples we simply used Markdown's backtick syntax: https://www.markdownguide.org/basic-syntax/#code

BjoernKW··on Ask HN: What are the best eBook authoring tools today?
For "Stratospheric - From Zero to Production with Spring Boot and AWS" (https://stratospheric.dev/) we used IntelliJ IDEA.

For a technical ebook with lots of code samples using our trusted IDE just was the natural choice.

BjoernKW··on Are Bluetooth beacons still a thing?
> And totally insecure --- as in anyone can make a copy and share it.

Which is totally fine for the use case at hand and not a security issue at all, in this case. For other use cases, such as advertising, sharing would even be desired behaviour.

A possible security issue for the museum use case rather would be a malicious actor replacing the QR code with their own, thereby trying to have visitors download malware to their phones.

BjoernKW··on Ask HN: Tips for generating easy to remember but difficult to crack passwords
These days, password managers such as 1Password are easy enough to use even for non-tech-savvy people.

Other than that, although the process can become tedious when applied manually to a multitude of passwords, diceware helps with generating easy-to-remember passwords:

You probably still want to keep a secure record of those somewhere, which is where password managers come in handy again.

BjoernKW··on Why Are So Many Dogs on Prozac?
Sexual dysfunction, for one.

Additional potential long-term side effects include, but are not limited to, weight gain, feeling emotionally numb, and increased suicide risk.

Furthermore, there's the SSRI discontinuation syndrome.

BjoernKW··on Why Are So Many Dogs on Prozac?
We don’t really know how SSRIs work - or if at all (at least not as intended) - yet they’re handed out indiscriminately for “treating” anything that isn’t “normal”, accepted, or desired behaviour.

These drugs have life-altering - and often permanent - side effects to the extent they’re a case of the cure being worse than the disease for any but the most severe and otherwise untreatable conditions and hence run against basic ethical standards in medicine (“Do no harm.” for one).

Feeding that type of drug to a poor dog, who can neither decide for themselves nor know what’s happening to them, takes a special kind of unethical.

On the other hand, it’s not like the standards around SSRIs for treating humans are ethical either.

Their side effects often are downplayed or kept from patients, who will take those drugs at their doctor’s recommendation, not knowing the full extent of what they have subscribed to.

SSRIs are truly fun stuff.

BjoernKW··on Low serotonin levels might explain some Long Covid symptoms, study proposes
I'd be very careful with SSRIs. This might very well turn out to be a case of the cure being worse than the disease.

> If this turns out to be as interesting as it sounds, well buy SSRI maker stocks

Unfortunately, that suggestion on the other hand might be spot-on. Not because SSRIs truly are the cure-all they're often marketed as, but rather because manufacturers have managed to sell them as such.

> [...] is a viral reservoir, possibly in the gut

In that case, a gastrointestinal lavage (as applied before a colonoscopy) could be a potential remedy. It's a long shot, but since the process doesn't have any side effects (other than the inconvenience of having to change your diet for a few days), it'd be worth a try.

> So people and doctors will throw SSRIs at the problem, and maybe that will relieve some symptoms, but will not address the fundamental cause.

Additionally, SSRIs cause severe - and in many cases permanent - side effects. What's worse, we don't even really know how SSRIs work - or if at all (at least, as intended). Nevertheless, they're handed out like sweets.

BjoernKW··on The one database/file/zip to save humanity, what is it?
Those properties are not what people commonly think of when they attribute value to gold, though.

In particular, the idea that gold is a crisis-proof currency has nothing to do with these properties, but rather the notion that because its supply is limited (in contrast to fiat money) and it can't be reproduced or counterfeited, it will be accepted as a medium of exchange even in the most dire economic scenarios such as a complete societal collapse.

Perhaps paradoxically, though, in such a scenario gold has particularly little - if any - remaining economic value.

BjoernKW··on The one database/file/zip to save humanity, what is it?
> economic value comes from government dictate

Quite to the contrary. Economic value originates from the benefit a product or service provides, nothing else.

Currency (particularly if of the fiat money variety) on the other hand, has no inherent value: You can't eat it, you can't use it to build something. Its value depends entirely on the trust people have in the issuing authority.

BjoernKW··on The one database/file/zip to save humanity, what is it?
Those are physical properties rather than economic ones. Gold not oxidising (and metal elements in general being durable) makes it a natural medium for exchanging value. However, that value still is imaginary.

Without being backed by a country / an economic system, and the mere belief that it is valuable, gold has very little value, especially when considering what essentially is a doomsday scenario, in which people probably have more pressing needs than refining and processing gold.

BjoernKW··on The one database/file/zip to save humanity, what is it?
I will never understand the idea of gold as a supposedly crisis-proof currency.

How is hoarding pieces of a shiny but for the most part inherently worthless metal going to help you during a global war?

If you're alluding to an all-out economic and societal collapse: In that case, gold will be just as useless as legal tender. Rather, under such extreme circumstances, we'd probably see a reversion to a barter economy.

BjoernKW··on Metric Time
I fondly remember Swatch Internet Time and .beats. Back then (around 1998), I used to have a watch that displayed Internet Time and I genuinely believed that this was going to the future way of how we keep track of time and synchronise with each other.

Unfortunately, things turned out differently.
