ruste··on How to live on $432 a month in America
I've been following this guy for a while on X. He does live this way. This isn't a hypothetical. He lives on his writing and has plenty of free time to chop all the wood he'd ever need.
ruste··on Ask HN: Programmable Lasers?
I actually did this at one point in time. The hardware you're looking for is a "laser galvo" setup. It typically takes a +/-12v range analog signal as input. I ended up building my own hardware to drive this. You can use a D to A converter and an op-amp to take a digital output from a raspberry pi or arduino and get the correct signal level. I ran mine on an arduino and it was plenty fast for simple things. Complex animations that require more compute on the device might be a bit much. Enabling and disabling the laser is as simple as a transistor.
ruste··on Bend: a high-level language that runs on GPUs (via HVM2)
Been watching your development for a while on Twitter. This is a monumental achievement and I hope it gets the recognition it deserves.
ruste··on The 'Georgists' Are Out and they want to tax your land
I probably could have been clearer with my point. A park is never the highest and best use based on gain. A LVT would make it _harder_ to create things that may be valuable in ways not measured by the market.
ruste··on The 'Georgists' Are Out and they want to tax your land
The problem with this is that it's fundamentally incompatible with zoning.

I own a chunk of acreage in farmland adjacent to my metropolitan area. The township won't allow it to be developed further due to density restrictions, I have my one house on it but that's all I get and I'm happy with that, but his tax would be implemented at the state level. The state would say "You have a lot of valuable land here right next to the city. We're going to tax you wildly on land you can't develop.

Furthermore, this tax would just serve to increase speculative churn and encourage chunks of land that would eventually go on to become parks and public lands to be broken down by landowners into small chunks for the densest and most valuable uses.

The whole problem is that what is valuable is not necessarily what is good for society and this does nothing to address that. I'm always struck by how weirdly free-market / Laissez faire land value taxes are given who typically pushes them.

ruste··on Lfortran: Modern interactive LLVM-based Fortran compiler
This is probably fantastic from a maintainability perspective, but I'm curious if some performance is left on the table by using LLVM IR instead of compiling directly to machine code. I know there are a number of optimizations that can be made for Fortran that can't be made for C-like languages and I wonder if some of those C-like assumptions are implicitly encoded in the IR.
ruste··on Night of the living brain fog dead or how I hacked myself better via open source
The author is in the UK. They noted that they were on a wait-list just to get tested and likely wouldn't be for a year at least so they decided to take it on themselves.
ruste··on APL: An Array Oriented Programming Language (2018)
The advantage of single character concatenated symbols is that it allows your brain to group them rather than forcing you to read them separately. This means you almost unconsciously build up a bunch of set of instantly recognizable "chunks" of symbols that represent concepts you're familiar with. Each of these chunks can represent the equivalent of a huge amount of code in another language.
ruste··on I deleted all my social media 3 yrs ago and I hardcore regret it everyday
I've tried a few times to export my data from Facebook and it's never worked for me. I request it and it just silently fails.
ruste··on Startup Uses GPT-3 to Provide Counseling and Then Realizes It 'Feels Weird'
A lot of the benefit of therapy likely comes from the social aspect of feeling understood and seen by another _person_. This can't come from an AI as long as those treated know it's an AI.
ruste··on Ask HN: What sub $200 product improved your 2022
Personally the return on the air fryer for me is a direct result of it being smaller. For most things my larger kitchen oven needs time to preheat. That's an additional step that isn't required when I just want to roast some vegetables / meat or heat some frozen potato products quickly in the air fryer. This time / extra step is well worth cost for me ($20 of fb marketplace).
ruste··on We are drowning in information while starving for wisdom (2021)
I love how quickly after ChatGPT's release we're conflating the chicken and the egg. It's not that the content online is barely better than ChatGPT. ChatGPT is what it is because it was trained on that content.
ruste··on Louis Rossmann explains why he left New York
He has! One of the things he mentions in this and other videos is that not even the CPAs he hired can answer if something is legal. He's also got recordings of him calling the city repeatedly about a fine and nobody can tell him how to avoid it, when it applies, or whether what he's doing is even legal.
ruste··on Dwarf Fortress’ graphical upgrade provides a new way into a wildly wonky game
Lower your population cap in the config file (I like 10-15) and don't pierce the cavern layers. This was a total gamechanger for me in terms of fun and fps :)
ruste··on Researchers develop thermoformable ceramics, 'a new frontier in materials'
The only way I've seen this done is by lapping the touching surfaces after firing.
ruste··on TikTok videos leave teens thinking they have rare mental disorders (2021)
Didn't facebook / instagram have to testify before congress only a couple of years ago about what they were doing to fight the body image issues that their platforms were causing in underage users?
ruste··on Gun owners’ private information leaked by California Attorney General
Most burglaries happen when the occupant isn't home. Unsurprisingly burglars don't like people to be there when they break in. Guns don't operate themselves so it's not crazy to think that people who have them would have their homes targeted.
ruste··on Gun owners’ private information leaked by California Attorney General
The reason guns are the number two deterrent behind dogs is because the overwhelming majority of burglaries generally, and in particular, for the purpose of theft, happen when the homeowner is gone. A gun won't operate itself, but people often leave their dogs home alone.

Given this context, the fear that those looking for guns would use this information to target a relative minority that have them becomes much more plausible.

ruste··on Show HN: MiniMail – Disposable Email Service for Everyone
https://www.guerrillamail.com/ has been around as long as I can remember.
ruste··on A wild turkey is attacking people in D.C.
You lead such an interesting and different life than me to have been bitten by enough birds to have comparison points. How did you get here?
ruste··on A wild turkey is attacking people in D.C.
Farm raised turkeys are too large to fly or even reproduce independently. Wild turkeys happily fly though I'm not sure how far.
ruste··on Two weeks later David Bennett is alive, his pig’s heart beating soundly
That sounds severe enough I'd consider it worthwhile to pay a lab to run spectroscopy on a range of supplements just in case, or consider hiring a lab to synthesize a batch I _know_ will meet my needs. The first option is probably a lot less pricey than you'd expect.
ruste··on Bitcoin value tumbles almost 50% since record November
Clear misunderstanding of the economics in this article. Bitcoin is a stable store of value. Every other Currency just deflated 100% simultaneously and the cost of all goods as represented by bitcoin also went up 100%!
ruste··on Scientists vacuum zoo animals' DNA out of the air
This honestly scares me more than the new Wi-Fi standards that can sense through walls. This feels like it allows for much more ubiquitous surveillance. They might not know your precise location, but they'll always have a rough idea where you've been making it impossible to avoid more precise tech.
ruste··on It is difficult for the average person to conceive of how useless NFTs are
This is close but not quite how I expect they'll come to be used. I think they'll become a lot more important if companies like Meta are successful in creating virtual connected spaces based on open standards. In that scenario, with public buy in, ownership of a digital work shifts meaning slightly to one where NFTs suddenly make more sense.
ruste··on Boston Dynamics’ Stretch robot can move 800 heavy boxes per hour
I don't think this is as much of a constraint as you'd expect. Imagine you manage to pull 1 psi over a 10x10" patch of box. That's 100lb of lifting force. If you're worried about whether the cardboard can handle it spread the area and lower the pressure more. I don't think 1lb per square inch of cardboard would be an issue and it looks like they have more surface area for suction than that.
ruste··on Major nuclear fusion milestone reached as ‘ignition’ triggered in a lab
When thinking of this amount of energy in kWh it seems small, but if this is deposited by lasers in a small fraction of a second it seems like a huge amount of power delivery.
ruste··on How to replace estimations and guesses with a Monte Carlo simulation
I've actually been working on turning this idea into a product for the past year or two. Looks like I'm not the only one to have thought of this!
ruste··on Learning Common Lisp to beat Java and Rust on a phone encoding problem
I'd also like to know. I'm considering writing some for fun in GNU APL right now.
ruste··on Decision Making Under Uncertainty with POMDPs.jl
Thanks for the explanation! I'm actually working on a tool right now that uses a similar process, but haven't had much of a formal background. Looks like I'll be adding quite a bit to my reading list!
