xvedejas··on Surprising public health benefit of unemployment?
Or do what many urban areas do efficiently: make it easy to commute by train. Even a bus commute cuts down the tire pollution per commuter significantly. Building more housing near job centers can help both shorten commutes and make mass transit more desirable.
xvedejas··on California is gripped by economic problems, with no easy fix
The problem is the kind of taxation, not the amount. Beyond the fact that property tax is less of a burden on economic activity than income tax, it's also the case that property tax is less likely to bankrupt the state because of reduced revenue during economic downturns.
xvedejas··on The lithium-ion battery may not be the best bet for EVs
it's LiFePO4 (aka LFP, Lithium Iron Phosphate), unless there's a new Polonium version I haven't heard of
xvedejas··on Satoshi – Sirius emails 2009-2011
I used to think so too, but the case for Len Sassaman is similarly strong.
xvedejas··on The boundary of neural network trainability is fractal
If the units are different, you do need to come up with a conversation between them, or you're implicitly saying it's 1-to-1
xvedejas··on The boundary of neural network trainability is fractal
Complex numbers multiplied by an imaginary number rotate preserving magnitude. In this sense they have the same units.
xvedejas··on Berkeley's upzoning would be among nation's largest
My colleague lives in a European city which has undergone a building boom, and it was surprising to me how density doesn't just mean more people per area, but also more area per person. A very spacious apartment is much more affordable there than in any major US city, and more people therefore get more space to themselves. It's kind of amazing how much more livable that arrangement is.
xvedejas··on Why we stopped building cut and cover
In an ideal world, housing wouldn't be built immediately on major transit lines, but a (walkable) short distance away. Alas, city planners seem dead-set that new construction must _only_ happen within a block of major roads or train lines. There seems to be a lot of urban malpractice that prevents us from making good choices.
xvedejas··on Rust wont save us, but its ideas will
safe Rust isn't just the borrow checker, it's also:

  - no uninitialized memory
  - clone vs copy semantics as part of the type system
  - Send, Sync, "fearless concurrency"
  - no unchecked indexing
  - type safety (you can't just cast things like in C)
I do think these are clear complements to a borrow checker, since it's all in the interest of preventing undefined behavior. Yet, there are even more nice modern features of Rust that C lacks:

  - hygienic macros
  - namespaces
  - pattern matching
  - modern build/package system

the wise man bowed his head solemnly and spoke: "theres actually zero difference between good & bad things. you imbecile. you fucking moron"
xvedejas··on Business advice plagued by survivor bias (2009)
This is assuming uncorrelated results too. As you observe more and more of your businesses failing, you would want to update your estimate of your own rate of failure. Each new failure in a string of only failures is slight evidence that your own rate of failure may be >90%, even if it's 90% on average for everyone.
xvedejas··on How different languages laugh online
In a certain gaming community, we laugh not with "lol" but with "11", since that plays a laughing taunt. This extends to chats outside of the game itself
xvedejas··on The case for single-stair multifamily
From what I've seen of environmental review laws, they mostly just have to do with noise and construction nuisance. Whereas community review is mostly about aesthetics. I don't think these are the tools designed for safety.
xvedejas··on Immediate Mode GUI Programming
Have you looked into slint? I'm curious to hear other Rust devs' experience with it.
xvedejas··on Value of life
Right: unlike dying, if someone sits in traffic more, they're able to change their situation and seek alternatives. It's not like increasing traffic in the short term is something reasonable to extrapolate to all drivers for the rest of their lives. More likely, traffic increases lead to either (or both) of infrastructure changes or lifestyle changes.
xvedejas··on Half of high school seniors won't apply to colleges costing more than $40k
I am not sure if you're in agreement or not, but yes, loans help access things that cost money (like basic needs) in the case that earnings are deferred due to education. Student loans generally require no payments until 6 months after education ends.
xvedejas··on Half of high school seniors won't apply to colleges costing more than $40k
I held a similar level of student loan debt, and it was worth it. My earnings are much larger thanks to the degree it enabled me to pursue, and I was able to pay it off early. While I don't think the system is ideal, just the existence of student debt isn't indicative of an issue, we'd need to look at statistics around what proportion of borrowers have undue hardship as a result.
xvedejas··on How random is xkcd? (2015)
I think this is the correct way to phrase it. Just because the probabilities of each are both 50% doesn't mean it's more likely than not to get the same number of ones and zeros. It would just mean you're equally likely to get a few more ones as you are to get a few more zeros. But the counts are unlikely to be very far apart.
xvedejas··on Reindeer sleep and eat simultaneously
this is a common symptom of narcolepsy, at least.
xvedejas··on A bike lane moved, and this San Francisco neighborhood erupted
Yes, they are plastic and designed to be driven over. Although, many of them are noticeably damaged already, so I can't imagine they're expected to be driven over so often?
xvedejas··on A bike lane moved, and this San Francisco neighborhood erupted
These lanes are confusing and dangerous in my experience. I choose to bike on folsom instead now. We have great protected bike lanes elsewhere in the city (valencia between market and 15th, folsom north of division) and I don't understand why we couldn't just go with that instead of experimenting on the valencia corridor.

To be clear for anyone not familiar: Valencia already had bike lanes, and that's not the problem. The problem is that the new design is more fragile to bad driver behavior, since drivers run over the flex posts to pass stopped vehicles, and make the whole corridor a mess for everyone.

xvedejas··on How are startups shaped by macro conditions at birth?
What part of today would have you worried? My start up is having a great time finding people (amid tech layoffs) and our office space is heavily discounted due to WFH/high office vacancies. Our sales are going well also (our industry has been booming). It seems to me like a good time as any to build a company.
xvedejas··on San Francisco Blows Housing Deadline, Prompting Standoff with State Regulators
I can't vote for 10 out of 11 of SF city supervisors, but they get to prevent my neighborhood from building more housing. I feel like whatever ideals you have about democracy here, they don't exist in practice in San Francisco for various reasons. I'm extremely glad my elected state government can step in for the greater cohesion of democratic voices across the state and override the hyper-local politics.
xvedejas··on Charging a lithium battery to 80% only?
Because of the flatness of the voltage curve, limiting your charge to the middle range makes the state-of-charge estimation a much more difficult problem (less voltage signal). So there's actually a trade-off between longevity and accuracy of charge reporting.
xvedejas··on The Myth of RAM (2014)
It depends what you mean by "numbers": all integers or just 64-bit ones?
xvedejas··on Disappearing Polymorphs
Are there any promising paths towards preventing this? Seeding clean rooms with other chiral molecules that can encourage the lost higher energy form of a crystal, maybe?
xvedejas··on Was Rust Worth It?
I believe procedural macros always need to be defined in a separate crate, so at least all projects that use procedural macros will have multiple crates
xvedejas··on 22-year-old builds chips in his parents' garage (2022)
Your comment seems unnecessarily antagonistic.

Given whatever size of garage I have, being somewhere I can live without a car gives me more garage space, regardless of whether it's a suburb. If I want to maximize garage space given my choice of a car-free lifestyle, I would probably move to a suburb with a good train station, not one where "only 20 minutes' drive to downtown" is seen as the selling point. Those are subtly different kinds of places, in my experience, where most people are going to fill their garage space with cars.

That you need to drive to downtown suggests you might not have much garage space after all?
