entangledqubit··on How to design a house to last 1000 years
Maybe tungsten molds instead?
entangledqubit··on How to design a house to last 1000 years
There is also basalt rebar. Last I checked, some building codes allow equivalent 1:1 tradeoff with classic rebar - even though the basalt rebar is stronger.

From what I understand, basalt rebar does not have the usual problem of regular rebar where oxidizing (rust) expansion can cause cracking in concrete. Additionally, the temperature expansion rates are much closer (rebar vs concrete).

My main hesitation would be that it is relatively new so we don't have that much data on how well it ages. Overall, it seems better than rebar classic by far (other than cost - which hasn't been scaled) - but I don't build structures for a living.

entangledqubit··on How Dwarf Fortress is built
What state are you looking to access/mutate? To me, a large part of the fun from the DF experience came from only being able to twiddle the high level knobs and watch the shenanigans emerge.

I also got the impression that low level interventions may not be usefully realizable in the codebase.

entangledqubit··on Regulators Shut Down Lending Platform (YC Alum) LendUp
Based on my own experiences (around same age) and discussions with friends, the depth of your financial education is the exception. The checkbook one comes up a regularly, while loans and interest rates come up in the context of math classes.

I guess I'd also be curious how deep those topics went. Like for apartment leases, notions of how to find out tenants rights in your area and how to push back on bad landlords. For budgets, what do you do if you can't make a budget work. Things to watch out for when considering employers and common scams.

A lot of this stuff I was able to pick up over the years but if you get screwed early on it can really affect your life trajectory. Sources seem less objective than when I was learning this stuff.

If you're first gen semi-wealthy - say a SWE in the valley - there's a whole other education that's necessary... I have talked to many SWEs that don't understand their comp.

Also, to make sure there's enough prey, let's not make financial education a requirement, in general, so people can make well reasoned choices...
entangledqubit··on Internet Archive as a default host-of-record for startups
I'd also like to see the rest of the assumptions baked in. Is there some trust fund involved -- which requires that we now consider the risk associated with how the $2 is invested to get an adequate return?
entangledqubit··on Google Drive could soon start locking your files
I think the general consensus is that you shouldn't just leave them on a shelf for more than a year and that there is some temperature dependency in there.

If you really care about the data, two+ backups stored in different places is completely reasonable. Note that "places" is not limited by physical as trying to maintain independent dependency chains (e.g. a durable storage provider may decide to cut off account access so maybe a second independent storage provider using a different credit card makes sense)

Your OCD may also be helped a bit by having some way to verify you backups (e.g. use ZFS and scrub regularly and/or separate hash manifests of the files).

entangledqubit··on Here’s How Many People Default on Their Student Loans in the U.S.
From what I understand, in the US it's much easier to walk away from a mortgage (with an underlying asset to reclaim) than student loans. I'm under the impression that this (and government default guarantees) makes lenders more willing to lend money. I'm curious if tuition would have risen as much if lenders were less willing to lend money due to structural changes (e.g. actually being able to lose money).
entangledqubit··on California is the only state to hide its spending – nearly $300B a year
How widely spread are these heavily funded PTA setups in CA? Base on my limited visibility while living in SF and on the peninsula, this setup seems to run rampant -- for the areas with people that can afford it. Is any of the funding gathered devoted to legislating for fixing funding for all kids in the state?
entangledqubit··on Does Georgism work? Is land a big deal?
At least for Seattle, the assessor's office has a breakdown but it turns out to be fairly bogus unless there's been a remodel or new building -- resulting in a new assessment. Quite a few cities also seem to have pretty bogus values on the books.
entangledqubit··on Methane plume seen by satellite over Alabama mystifies experts
If they image repeatedly at various offsets over an area - perhaps over multiple flybys - shouldn't they be able to localize it better than that?

The Wikipedia pages claims that pictures are taken every second but I am not sure how that translates to image density on the ground.

entangledqubit··on The metaverse is already here – it's Minecraft
Transferring objects from one world to another may not be desirable for a few reasons. This could lead to coupling of world economies where something that is meant to be - intentionally - scarce in one world now finds itself with an overabundance.
entangledqubit··on John Carmack pushes out unlocked OS for defunct Oculus Go headset
> I think this goes somewhat beyond right to repair?

Definitely goes beyond it. This should be able to get traction as an anti-electronics waste policy.

Designs and relevant documentation should be packaged up and handed over to the Library of Congress (or alternate entity) as soon as any design goes into mass production. LoC may release them when the product is no longer supported by the manufacturer or the company has gone out of business -- which could be fairly automated on the LoC side.

One side-effect of this may be that companies will be incentivized to support hardware longer, if they believe that these designs have notable design elements that they do not wish to disclose.

I'd settle for something non-retroactive. Since I don't think that'd be tenable technically at this point anyway.

One of the cruxes in this are things like GPUs and wireless chips which are pretty unfriendly in terms of getting documentation but even providing a subset of functionality would be great.

entangledqubit··on Ask HN: Best way to host a website for 500 years?
Encode the personal page into a best-selling novel that becomes a classic across the world. The rest of civilization will deal with the redundant storage for you.

If it's small enough, encode it into a catchy children's song or rhyme.

entangledqubit··on Understanding Startup Offers
The questions included here are good to see.

For a more complete guide, my preferred document these days is the Holloway Guide ( https://www.holloway.com/g/equity-compensation ). Though now I have to add a warning that there's a slightly annoying attempt to get your contact info and it has gotten rather long...

entangledqubit··on The growing market of not cutting down trees
For those familiar with American building practices, it's interesting to see some stark contrasts. This video discusses solid timber walls (among other interesting features) in a Swiss building project: https://www.youtube.com/watch?v=RlplalGNfFM
entangledqubit··on Moving Avoids California Tax? Not So Fast
Not a tax expert but IIRC since they were earned in CA, they generally are taxed when they result in a net gain of some sort (e.g. sold directly or exercised). Go to Section E of the FTB's publication 1100.
entangledqubit··on Reddit raises $410M in new funding
I tried it recently (< 2 months ago) and the experience wasn't too bad. This was the first real ad "campaign" I had ever set up. The targeted group was pretty niche and while Reddit suggested going broader, I was able to stick with the subreddits that I considered relevant.

The most annoying part was the rather opaque period between launching, approving, and actually running the ad. The first real confirmation I had that things were working was a bill.

entangledqubit··on The death of the ‘Millionaire Next Door’ dream
I suspect that most people decry subsidized inherited wealth through things like stepping-up the cost basis for inherited wealth. Generally, I don't think people have a problem with parents giving their kids gifts in some form - though I do acknowledge that there probably is some notion of what is considered a (un)reasonable upper limit.
entangledqubit··on Americans Are Pretty Skeptical That Hard Work Will Pay Off
Generally, I agree you. In engineering orgs, it seems like the social dynamics of the org distribute who is perceived to be creating that value in a non-average way. e.g. the engineers improving reliability are probably perceived as less valuable than engineers putting out user visible changes. This seems to be what happens by default, unless leadership is self-aware enough to mitigate.

Attributing revenue to the short order cook is a lot easier than the engineer. (Sales people are also easier to quantify.)

entangledqubit··on Amazon Appstore will reduce its developer revenue cut
Isn't any compute more-or-less transferable (presumably at less than AWS's dollar cost) if you take it and mine some currency with it? I assume there's something out there that effectively buy spares cycles if you install a client. Or resell S3 space. (And yes, this may be potentially dangerous to your AWS account reputation.)
entangledqubit··on 21st Century Baker's Tent
To reiterate what others have said, do not run a fuel burning stove in a tent. I've heard several stories about people dying from carbon monoxide poisoning while trying to keep warm with a stove in their tent. (One about a parent and child in a national park is burned into my brain.) I suspect that people assume the fabric "breathes" sufficiently.

If you need to boost the warmth of your tent, boil some water outside, put it in a container, and keep that in your tent (being careful of scalding, of course).

entangledqubit··on NVMe is not a hard disk
I thought along that route as well but I'm not sure how the feature scale of a fuse compares to the size of a flash cell - especially since the latter can contain multiple bits worth of info (MLC). Assuming the fuse write results in a serious physical state change of some sort, I suspect that the energy required for high speed writes (at SSD speeds) may become substantial.

That being said, it's not clear how innovation has occurred in this direction in the storage space.

entangledqubit··on NVMe is not a hard disk
I suspect that hawki was assuming that a WORM SSD would be based on a different non-flash storage medium. I don't know any write once media that has similar read/write access times to an SSD.

FWIW, there are WORM microsd cards available but it looks like they still use flash under the hood.

entangledqubit··on Ohio sues Google, seeks to declare the internet company a public utility
Then you can also play a tragedy-of-the-commons aquifer game with all the commercial users of water in your area. Can you afford to keep making your well deeper than theirs? There are a few towns in California engaged in the resulting endgame.
entangledqubit··on Ask HN: How can an older worker going back to CS after a break find a position?
IIRC, Google had a program that originally targeted this demographic and has since broadened their scope. If the acquaintance talks to a recruiter there, ask about "engineering residency".
entangledqubit··on Facebook prevents sharing New York Post story on BLM co-founder's real estate
Yes. Also, if this is a concern, the property involved may never have been publicly listed as for sale.
entangledqubit··on Amazon workers vote against unionizing in Alabama
Reply to the sibling comment comparing to insurance of MS SWE. While the absolute values are comparable, $1500 is quite a bit more of an inconvenience at a warehouser worker pay level than at a SWE salary level.

Given the physical nature of the work, I'd consider them more enlightened if they provided a lower deductible at the $0 premium level for every warehouse worker across the board. I'm really getting tired of places treating the long term mental and physical health of workers as an unpriced externality that's later paid for by society.

Also, thanks to motardo for the data point. (I will assume you're an actual warehouse worker.)

entangledqubit··on My apartment was built on toxic waste
In many cases they do but neglect to adequately inform employees that may be potentially be affected. At the Google Quad campus in Mountain View there was an incident where some ventilation fans were accidentally turned off which caused employees to be exposed to TCE (affects embryo development so mainly concerning to pregnant employees) that is leeching up from the ground. I'm pretty sure that 99% of the people would not have been able to tell you it was a risk in working there.

Also in the area is the "MEW plume". When I asked realtors about it while looking for real estate in the area they all claimed to know nothing about it - despite being locals and there being land development rules requiring that top soil be carted away to be treated.

So many people/orgs are tacitly working together to ignore the problem since no one wants to be inconvenienced or left holding the bag.
