A_No_Name_Mouse··on Ask HN: Turned 25, Give Me Your Best Advice for the Next 25 Years?
Listen To the Baz Luhmann song "Everybody's Free (To Wear Sunscreen)". A lot of it is pretty good advice. I regret not having invested in index funds at that age. I'm very happy I backpacked the earth for 1.5 years as soon as I could afford it. When looking for a job: do the things you enjoy most, aim high and go for it. Do not try to find your calling: try different things and your calling will find you.
A_No_Name_Mouse··on Ask for no, don't ask for yes (2022)
This works great from a leadership perspective as well. If anyone is interested, I can recommend the book Turn the Ship Around! by David Marquet about this very subject.
A_No_Name_Mouse··on Something weird is happening with LLMs and Chess
Wouldn't surprise me if the outcome would have been exactly the same if instead of LLM's this was tried with a random selection of human beings :-)
A_No_Name_Mouse··on What Can We Hear in Space?
> Seismometers placed on Earth’s moon enable researchers to measure shudders and groans that are mainly caused by meteor impacts, and the squeezing and stretching of its interior by the tidal pull of the Earth.

How would the moon still be squeezed and stretched when it is now tidally locked to Earth?

You might be right. There's a link for deployment to Oracle cloud, but that seems to use a different way to login.

A_No_Name_Mouse··on Paper posits ultradense asteroid 33 Polyhymnia has transuranic elements
> Wait, you want to do a gravitational perturbation mission with 5kg, for a body of > 10^18kg? You'd have to do super duper precise measurements to notice anything I don't think so. We would measure the effect of 33 Polyhymnia on the probe, not the other way around. Which would work if it got just in the vicinity of the asteroid. The mass of the probe wouldn't even matter.

You're right of course about the density being a wild guess, probably not worth pursuing because the odds of finding something interesting are just about 0.

A_No_Name_Mouse··on A new basic taste joins sweet, salty, sour, bitter and umami
If the same receptor can distinguish between 2 distinct tastes I would consider it a different basic taste. In my experience ammonium chloride does not taste sourat all, so this might be the case. The article does not mention that though.

Did anyone check if the terms and conditions of 365 would allow Microsoft to use content processed by AI for AI training? I mean we trust Microsoft with our data already, but what if it regurgitates our internal company data to other users?
A_No_Name_Mouse··on Bosses Spend More Personal Time on Social Media Than Subordinates
I misread this as "bosses spend more time on social media than on their subordinates". I was ready to send this to my boss as a hint but alas.

Absolutely. The accompanying video gives you a sense of the absurd preciseness of this shot

I wouldn't mind a standard ChatGPT generated TL;DR as the first comment, with an archive link in case of a paywall.
A_No_Name_Mouse··on Ask HN: What are security exploits to try on personal wbsite?
I'd start with the OWASP top 10, https://owasp.org/Top10/ Depending on your tech stack and funtionality you could try SQL injection, CSRF or path traversal.

A_No_Name_Mouse··on I help seniors with technology issues
I'm 50 and I start to struggle. Not because I can't keep up with the tech but because I refuse to. No smart tv or doorbell, a 2004 unconnected car, physical light switches etc. I spend too much time figuring out what printer will not DRM me into buying branded ink. I wonder how much longer I can keep up with this, because everything is becoming smart and "as a service". It seems the perfect products for me are the products from 15 years ago that I can hardly buy any more.
A_No_Name_Mouse··on Milky Way's graveyard of dead stars found
> Supernova explosions are asymmetric, and the remnants are ejected at high speed—up to millions of kilometers per hour—and, even worse, this happens in an unknown and random direction for every object.

Doesn't this influence their usefulness as standard candles for measuring long distances? Or is luminosity of the supernova not affected by this?

A_No_Name_Mouse··on You want to know something about how bullshit insane our brains are? (2018)
That's what I do as well with tail lights of cars. There is a clear distinction between LED and normal lights: the LED's form a trail of dots.

A_No_Name_Mouse··on Mullvad is now available on Amazon
I assume that all national security agencies monitor all traffic and can already see I only connect to Mullvad. And I'm sure they will have noticed I use it when going through the logs of several SaaS services and see that it is always a Mullvad IP that uses my account. No secret IMHO
A_No_Name_Mouse··on Mullvad is now available on Amazon
What is the threat model where correlating the payment with the account number is the main threat? If you can relate the account number to Mullvad traffic, then isn't it far easier to monitor the traffic and see what IP is connecting through it (my local ISP IP)? And if you cannot, what harm is there in knowing someone uses Mullvad? I pay by bank card and I don't see the risk here.
A_No_Name_Mouse··on Flipper Zero – Portable Multi-Tool Device for Geeks
Just got mine a few days ago (EU based). Well built, works as promised. But I find that it mostly works for simple things like controlling lights, tv etc. Most interesting targets use proper encryption (mifare classic for example) so I had no luck accessing my company badge. Mifare Desire data cannot be read properly at the moment it seems, but I'm sure that will be fixed. Fun little tool, will probably end up in a drawer soon.
A_No_Name_Mouse··on Ask HN: Why are chess problems attack oriented?
You may be right about this. In some cases to turn an attack puzzle into a defense puzzle, I think it would be sufficient to use the same problem, but one turn earlier and switching sides. Then it may be possible to prevent the attack and the challenge becomes to spot and prevent it.
A_No_Name_Mouse··on Ask HN: Why are chess problems attack oriented?
The difference is that in an attack puzzle there is no way to prevent the attack, where in a defence puzzle there is, and you have to find out how. The outcome could be clearly defined, e.g. preventing the loss of a knight
A_No_Name_Mouse··on Some tiny personal programs I've written
Some of mine:

* A program to monitor a webcam aimed at a bird house to see if any bird occupies it

* A program to periodically send a 10 Hz tone to prevent my speakers from falling asleep, so that I don't miss the first part of a Teams call

* A program to monitor a MiFlora humidity sensor to alert me when my plants need watering

* A program to estimate number of cars and their speed in my street from a webcam

* A program to sync a subtitle with correct timing with a subtitle in the correct language

All hacked together Python scripts; I'm not a programmer

A_No_Name_Mouse··on Photons incoming: Webb team begins aligning the telescope
Obviously I'm wrong but I'm not sure why. Light bouncing off of two mirrors can interfere constructively or destructively, depending on the phase difference. The phase difference from light bouncing off of two aligned mirrors is random (as it's non coherent light). Adding a constant in the phase difference due to misalignment would still lead to a random difference. So it seems to me the phase shift wouldn't make a difference.

What am I missing?

A_No_Name_Mouse··on Photons incoming: Webb team begins aligning the telescope
> you can get interference between the paths

Yes I understand that: the single photon interference in the double slit experiment. But what two paths could a photon take in a telescope allowing it to interfere with itself? The mirrors are placed so far apart a photon could never bounce off more than one mirror?

A_No_Name_Mouse··on Photons incoming: Webb team begins aligning the telescope
For interference the light needs to be able to take two separate paths with different length, which is the case in the oil film example or with two slits. In a telescope, each photon can only take a single path. So what would it interfere with? If it's a different photon then coherence seems to be required
A_No_Name_Mouse··on Photons incoming: Webb team begins aligning the telescope
> Although Image Stacking puts all the light in one place on the detector, the segments are still acting as 18 small telescopes rather than one big one. The segments need to be lined up with each other with an accuracy smaller than the wavelength of the light.

Why is this necessary? Phase difference shouldn't matter unless the light is coherent, which I wouldn't expect in starlight. Which assumption is wrong?
