Why not use mdisc and effectively solve the “has my cd/dvd degraded beyond the point of being readable” question entirely.

You may not even be able to get real MDiscs any more [0] and I'm always extremely dubious of 1000 year lifespans since they're effectively impossible to test.

From the comments of that post:

> Hopefully this can put closure to the speculation. Our organization is a databank and is a big user of mdisc for archiving. We reached out to Verbatim last week about this Media Identification Code (MID) discrepancy. Here is their reply, in their own words ---- "The creator of the MDisc technology- Millenniata went out of business in 2017, they sold the technology to Mitsubishi, who until 2019 owned Verbatim. Due to this, the stamper ID changed, but the formula & the disc materials stayed the same. Mitsubishi sold Verbatim & all the technologies to CMC in December of 2020. Verbatim is the only company authorized to sell the original technology. Any Millenniata discs available were all produced before 2017 when the company shut down and any other brand is not the original technology." ----- So there it is, mdiscs with either the 'VERBAT' or 'MILLEN' prefix are fine. Just different production periods. Cheers.


Ah good catch. One big downside of reddit replacing forums is the default sorting does not make it easy to find late contributions like this.

M-Disc has such low capacity that you'd probably want a robot to burn it which is not cheap.

There are 100 GB BDXL flavors of M-Disc, but yeah definitely not enough for really large amounts of data but large enough to store a good chunk of my photos which is mostly what I'd want to keep around.

Videos would fill that up pretty quick though.


for storage of large volumes of data, mdisc is impractical. for storage of a few very important folders, sure.

note that only the cd-r flavor of mdisc is rated for long lifetime.

No.

Exactly.


> they should prioritize funding to states that are willing to relax permitting requirements and get shovels in the ground.

Another comment [0] is lamenting because that is exactly what they did.

States could get funding if they built the stations, which includes figuring out any permitting issues.

This hacker news post has more comments than the mailing list thread that inspired it. A roughly comparable amount of text. It’s a lot, but certainly doable.

That + having a couple decades to refine your email client setup goes a long way.


For a relatively in-depth take on this question: https://github.com/alex/what-happens-when


too outdated. even at the time of last commit (3y ago), lots is missing.


I mean yeah, it doesn't even touch what is happening inside your body in order to actually press those buttons. Or what forces are being converted and how they affect the surroundings.


You may say that as a joke, but looking back at my education, this is in part what I did later, after uni, when I thought about things to learn next. In my mind, I started explaining stuff in depth, and found the many many many holes in my apparently quite superficial school knowledge.

I think this would be excellent as a once-in-a-while exercise to teach the complexity of it all, after we went the other way to abstract the hell out of everything to make it more palatable. A reality check, so to speak, and as a check for everyone about the many holes in their understanding. Basically, in support of something that has been posted here more than once, this blog post: http://johnsalvatier.org/blog/2017/reality-has-a-surprising-...

In the last few years I read a lot of easily digestible progression fantasy on RoyalRoad. One frequent theme is rebirth or isekai on another world, one that's usually much more primitive. Often the main character starts bringing earth technology ideas into the new world. And every single time it is obvious that the authors very, VERY severely the complexity and difficulty of even the smallest thing that we take for granted. My favorite blog post describing an extremely simple product, and how large and sophisticated its supply chain is: https://medium.com/@kevin_ashton/what-coke-contains-221d4499...

To me, this shows that some more awareness of how much complexity there is in things might be valuable.

Being more aware of the connections across our abstractions also helps finding what's missing. It could also help to find optimizations across abstraction borders, instead of limiting oneself to only looking within ones favorite abstraction layer.

nevermind the article doesn't even exist anymore


Your version of the URL is missing the last few characters!

https://medium.com/@kevin_ashton/what-coke-contains-221d4499...

The last string part is, again and to be sure since the visible URL is shortened by H, what-coke-contains-221d449929ef

I think you copy-pasted the visible URL, which on HN is unreliable. Long URLs are shortened for display, you need to use the underlying link.

oh, oops!!! yes I did copy and paste it, I typically do that when quoting parts of comments. I didn't realize it truncated the URL lmao

thank you!


This would be an interesting way to frame an entire series of textbooks covering pretty much all of science, electrical engineering, and CS. The entire premise being "you type a URL into your browser and it loads the requested webpage".

Each textbook in the series at the depth of a bachelors degree, split by relevant subject including physics, chemistry, biology, neuroscience, materials science, electrical engineering, hardware design, kernel and device driver design, systems level networking, and all the remaining browser engine, VM, security, and webdev stuff.

To keep the task at least theoretically tractable cut off at the NIC in the local box.

Who knew you could premise a textbook on protein folding on "how a web page is loaded"?


great idea! i knew a physics professor once who developed an entire semester using "how racecars work" as his guiding light. i think he wrote a textbook, but i can't find it.

not: the physics of racecars, that is explaining racecar dynamics given physics fundamentals, rather explaining the fundamentals using racecars instead of spherical cows. i think not very different to first semester analog ee courses using hifi audio as the basis.


Or the decision to do it, the neurons involved, free will or otherwise.

Basically to load a web page you must first invent the universe.


Went for an interview, ended up with the existential dread.


I think it's funny to imagine the existential dread as a single unique instance of emotion that everything else feeds back into. Like - no, I'm not "having existential dread again", it's the same existential dread I've been having since the beginning...


And entropy when your browser garbage collects and free()


That’s true, but you could still play your NES.

As I understand it, this only applies to dispensaries where it is already allowed to consume on-site (which is not all dispensaries), and is regulated by local zoning laws, including (optionally) having sufficient smoke and ventilation systems.

> (F) The local jurisdiction considers whether to require adequate ventilation and filtration systems.

> (i) Ventilation and filtration systems are considered adequate for the purpose of this subparagraph if they prevent smoke and odors from migrating to any other part of the building hosting the consumption lounge or any neighboring building or grounds.


Reminds me of Cuil.

> Cuil worked on an automated encyclopedia called Cpedia, built by algorithmically summarizing and clustering ideas on the web to create encyclopedia-like reports. Instead of displaying search results, Cuil would show Cpedia articles matching the searched terms.

Rivians cost ~45% more per-unit than the postal vehicle (86k vs $59k), and doesn’t come in an ice variant, which the Post Office requires.


Why does it require a variant? Why can't the necessary ICE vehicles be one of the countless existing options?


Having a common platform for postal vehicles makes things like maintenance easier.


Seems like ice requirements don’t apply to every state


They don’t, but California essentially dictates them because nobody wants to cut themselves out of the richest state’s car sales


The ice requirement has nothing to do with California standards, which only applies to cars bought in California, which USPS doesn’t do.

Some postal routes are in cold climates with harsh winters where EVs would be impractical.
