lnauta··on ROOT: analyzing petabytes of data scientifically
Have they released v7 yet? When I started my PhD it they announced it, and I looked forward towards the consistency between certain parts of the software they would introduce (some mismatches really dont make sense and are clearly organic) and now I'm already 2 years past my graduation.
lnauta··on Discord Applying Forced Arbitration - opt-out before it is too late!
Not to be nitpicky but this message also talks of jury trial, which EU countries generally don't have.
lnauta··on What is Webb observing now?
This is really cool. And having that skymap makes it so much better!
lnauta··on Why are most sofas so bad?
When my grandma passed away I took the sofa because I was a poor student in need of a sofa. After about 10 years of daily use I started to notice some of the cushions sagging. Asked the family when she bought the couch and it predates my birth by about 10 years. Talk about quality.
lnauta··on I taught the Iliad to Chinese teenagers (2021)
Last summer I read a translation that tries to keep the rhyme and rythm. For parts I just got enchanted and kept reading and reading way longer than normal for me. How great it would be to hear this from someone who memorised it.
lnauta··on A steep rise of Hacker News in Google rankings
On top of that no sharing/@ing: no notifications for responses (there's probably an addon for that if you want it).

At first I thought I wouldn't like it, because I tend to post on subjects I'm knowledgeable and want to do my best there. But now I'm so glad to not get the anxiety and rush of the back and forth in heated discussions.

Peace and quiet.

lnauta··on Inside the proton, the ‘most complicated thing you could possibly imagine’
Quarks can not be alone, because of this confinement. What we see experimentally is that when we add energy to particles at some point they split into new particles and we never see a naked quarks.

We explain this by saying the quarks have a color charge and it must always be neutral. A single quark would be lets say red, but that's for some reason not possible. If we try to rip the quark out, it takes so much energy that this energy can be used to create another quark that results in a color neutral particle (red, antired)=meson, (red,green,blue)=baryon.

NB: this is a bit simplistic and other comments explain this quite in detail NB2: this color charge is just a name, its not an actual color

lnauta··on Inside the proton, the ‘most complicated thing you could possibly imagine’
It was a plasma of quarks and gluons first (these particles make up protons and neutrons and other unstable particles) which did cool down and become these particles. [https://en.m.wikipedia.org/wiki/Chronology_of_the_universe]

There is no reason to prefer any of the possible particles, but as all of them are unstable - minus the proton - they eventually decay to that state. (neutrons are not unstable in nuclei and such).

NB: this is quite simplistic and I skipped many details

lnauta··on Microsoft stole my Chrome tabs, and it wants yours, too
I did too. And later I did a bios upgrade that enabled the chip again and suddenly windows started showing me pop ups and telling me to upgrade.

After a lot of panic and powering down on an upgrade screen without a 'no' button I went to the bios and found my setting reset. Then I put a group policy in place not allowing such despicable behaviour.

lnauta··on What SoundCloud created can never die
Here are some of my favorite sets, the Kai Lie one is the best imo. And the 'taking you higher' series has many more parts (the one here is my favorite)

lnauta··on What SoundCloud created can never die
This makes me sad. I use SoundCloud to listen to one genre only (progressive trance for when I'm programming) and its gotten so good at recommending me exactly what I like. On top of that DJ sets are top notch.

There are many genres I like to listen to, but the result is a mix of all the things. It's quite rubbish to get a mix of very different genres spanning decades, which happens with Spotify all the time. And YouTube has been abandoned for all but the occasional song for me for similar reasons.

I'm not holding my breath on this sale as so many times the end result is for the worse. Guess I should see what else is out there.

lnauta··on Quairading shire erects signs telling travellers to ignore Google Maps
For a moment I thought this was about the Quiraing on Skye in Scotland.

My friends and I climbed it using Google maps, which ended up in us climbing some parts with hands and feet. When we realised we were off the path we made sure to avoid dangerous parts and make the best of it.

On the way down we could clearly see the normal path, while on the way up we took a path made by animals. The algorithm had recognised this path in the satellite images and steered us in that direction.

lnauta··on Block YouTube ads on AppleTV by decrypting and stripping ads from Profobuf
Excellent write up! I learned a lot and there's still much I did not fully understand.

In my spare time I got to the point in the article of trying to figure out which URLs are ads and blocking those with a pihole in section 4.11 and failing miserably. Cool to see some techniques I would never consider, and they work!

lnauta··on Block YouTube ads on AppleTV by decrypting and stripping ads from Profobuf
Indeed, how it is described in section 3.2 of the article is how I also did it on my home router+pihole combo. Still have add that rule 1 though, dns over tls.
lnauta··on Jellyfin: Free software media system
My raspberry pi has been slowly dying lately. Last thursday I ordered an ODROID C4, because pi's are overpriced at the moment.

At the same time I also moved from plex to jellyfin, and it's really nice, but some files stutter during playback in both the browser and on my chromecast.

Trying different hardware accelerated decoders did not help, so now I'm not sure what to do and debating to go back to plex. Although plex felt like it was getting worse in terms of functionality (I can't put my finger on it exactly).

lnauta··on Apple Vision Pro: Apple’s first spatial computer
After watching MKBHD talking about how amazing the eye tracking is, my first thought is:

When will apple start selling ads? They can use the eye tracking as feedback to advertisers, allowing apple to ask more money than non-eye tracked ads because they can prove you actually watched the ad.

Next you can track what people are looking at in netflix shows and adjust the shows to make them even more algorithmicly optimized (I dont even want to go there).

Interesting tech, but I think apple has something in mind we'll only realise a few years down the road (like how the app store turned out).

lnauta··on Imgur Updates TOS, Banning NSFW Content
Wow, I remember reading the post of the creator of imgur that he made it specifically for reddit use. Then at some point they made it into this social platform and removed directly linking to images (or at least made it quite hard).

Now this, interesting to see a site from day 1 coming up and (probably) going down.

lnauta··on Pi-hole: Network-wide ad blocking
I did exactly this to see how often my chromecast is signaling home. You know how often it contacts google? Over 10.000 times per day.
lnauta··on PFC bans are going to change waterproof garments
I have a jacket from that brand and you can put the greenland wax on it. This fall, when it got rainy I started applying it layer by layer to find how much you need and for vertical parts one or two is good enough. For elbows, shoulders and such, places that get really wet, at least five layers made it that being in the rain for 30 minutes is fine. This is about 1/4 of the wax bar. I hope I'm doing it right though!
lnauta··on Front end developers: stop moving things that I’m about to click on
Google with its 'related searches' that pops up because I clicked on a link and I am almost never interested in this extra information. When trying to filter the relevant javascript it breaks some other stuff on the page (last time I tried a few years ago). Grrmbl
lnauta··on The Bucks can’t wear cream uniforms because they interfere with digital ads
What I really hate about ads on YT (chromecast) especially is that they come with no warning. Just BAM, in your face. They have added a countdown recently which makes it better because I can anticipate my experience sucking and turn off the sound.
lnauta··on Meta fires a software engineer two days after he relocated from India to Canada
Going on on the whole fb/meta thing, I was wondering why people don't do the same for Alphabet. Everyone still calls it Google. But for facebook, the name was dropped almost immediately. Isn't that strange?
lnauta··on Ask HN: Ads triggered by WhatsApp “end to end encrypted” messages?
The reply all podcast has a nice episode on this, #109. Whether your phone is listening to your conversations.

They conclude that ads are shown to people you know. So you search for a product and then your partner gets ads for this product too, as they know you spend a lot of time together through other tracking methods.

lnauta··on Why do all these 20-somethings have closed captions turned on?
I have them on for games so I can read the conversation and skip to the next sentence. For open world RPG games that are 50+ hours long it really helps staying engaged, as some quest lines are not that interesting and I like to complete all side quests.
lnauta··on Speculoos-2c: A new potentially habitable earth
Also a great sandwich spread!
lnauta··on Declining quality of consumer-grade products – 2009 fridge compressor autopsy
My Bosch fridge from 2011 is still going strong. Cheapest model of the big fridges at 400€.
lnauta··on The great junk transfer is coming
When my grandma died we found something similar. We were getting more and more aggressive with shoving stuff into garbage bags, when my mom and aunt opened the closet and found clothes of my deceased grandfather. He had died ten years before my birth. Most of it was falling apart, except for a tuxedo that fitted me nicely! A good catch for a day of clearing out this apartment.
lnauta··on How light is a neutrino? The answer is closer than ever
To make it more complicated, they measure mass-squared! The original KATRIN article from 2019 (which I read at the time) measured a mass-squared of m^2 = (-1.0) +0.9 -1.1 eV^2. This is obviously unphysical, as a negative mass, let alone a negative mass-squared does not mean anything. (No they are not tachyons.) To get around this, some statistical tricks like "Feldman-Cousins" and others have to be used to construct a confidence interval that can be physically interpreted. I don't know the details of FC though, but it's widely used in low-statistics experiments.
lnauta··on How light is a neutrino? The answer is closer than ever
They measure what is called the 'effective mass', which is a combination of the masses of the mass-states.
lnauta··on Don't use text pixelation to redact sensitive information
This reminds me of one of my proudest moments in high school.

For a test in German class (my worst class), the teacher had just used tippex to remove some words and put them next to the text, and we had to fill them back in. I grabbed my ruler and measured all the sizes. There was 1 very long word, many medium sizes and a few smaller ones, but with this information and the context of the text for the first and last time I was able to get my first and last 10/10 in this class.
