timerol··on Saquon Barkley is playing for equity
Go Birds!
timerol··on 30 minutes with a stranger
Yes they can. For example, an ethnic minority could assume that a stupid white person is stupid because they're white. That would be a pretty clear cut case of racism
timerol··on The Relativity of Wrong (1988)
"All models are wrong. Some models are useful." is the way that I have heard this thesis quipped. I suppose "All models are wrong. Some models are more wrong than others." would fit Asimov's points better, but I've never actually heard that one
timerol··on Standard Thermal: Energy Storage 500x Cheaper Than Batteries
Exowatt requires rethinking the solar energy system entirely. This is meant to be bolted onto an existing solar panel field that is mostly selling energy to the grid, but gets curtailed sometimes
timerol··on This website is for humans
.. if you read the full article, you would have learned that "I subscribe to a lot of recipe websites via RSS, and look forward to new posts from some of my favourites", which is a much different way of consuming recipes than you proposed
timerol··on This website is for humans
For recipes specifically, yes. I am not much of a chef, and, when initially learning, I often used to search for a recipe based on a few ingredients I wanted to use. I was never looking for an expert's take on a crafted meal, I was exactly looking for something "that kind of resembles what you’re looking for, but without any of the credibility or soul". Frankly I'm amazed that recipes were used as the example in the article, but to each their own

timerol··on Our $100M Series B
> Does everyone at Oxide have the same equity grant?

> equity compensates for risk – and in a startup, risk reduces over time: the first employee takes much more risk than the hundredth.

I think that paragraph answers the question pretty clearly. As an Oxide employee you will get equity. It will generally be less than the people that came before you, but more than people that come after you. So it's obviously not the same as everyone else

timerol··on Learning Is Slower Than You Think
This article seems to be a good argument for a school that's 3/4 project based learning and 1/4 classroom instruction. The author then tries very hard to pretend that Alpha school does not follow that model, and is instead something else - a boogeyman of blitzing through lessons without any opportunity for application or reflection, as opposed to the reality of a mix of classroom instruction and project-based learning to struggle with the concepts learned.

> And some readers may ask: if schools like Alpha accelerate the basics and then give students space to explore—what’s wrong with that?

> The problem isn’t the intention—it’s the architecture. You can’t optimize one part of a child and expect the rest to unfold naturally. Learning isn’t modular. Once efficiency takes hold, it doesn’t stay in its lane. It reshapes what matters.

The argument, if I'm following it, is that the Alpha model is going to do well, and therefore the model will change to remove the current 3/4 of the curriculum used for exploration, which will make the model worse. But Alpha won't care, because teaching students worse in the name of efficiency is the natural end point. I am not convinced.

I think the article would have done a much better job starting with Asian cram school culture and how AI tutoring is being "fueled by state incentives and parental anxiety", instead of having that as a throwaway thought in the middle of an article otherwise focused on Alpha school.

The combination of "When documenting" and referencing "J3" indicates that dlcarrier is referencing a limitation of a specific port on a product that they worked on, not a set of global limitations on any 8P8C connectors
timerol··on GLP-1s are breaking life insurance
So you pay less than 1% of the cost to rebuild your home per year in home insurance, in a state that regularly has fires, floods, and earthquakes? That seems fair to me
timerol··on Impacts of adding PV solar system to internal combustion engine vehicles
10% of the battery per day, which would cover all of my driving other than the rare long road trip. I have plenty of weekends where I drive 200 miles, but then the battery would recharge over the week when I drive less than 40 miles a day

> I don’t know—I didn’t watch it, lol. That was the whole point. And if that answer makes you uncomfortable, buckle-up for this future we're hurtling toward. Boy, howdy.

This is a great bit of work, and the author accurately summarizes my discomfort

timerol··on Worldwide power grid with glass insulated HVDC cables
> The cable, if snagged by a ship anchor, would catastrophically fail. Not only would it snap, but the internal stresses would propagate the crack along the entire length.

I admire that the author wrote this sentence and continued with the thought experiment anyway

timerol··on Why quadratic funding is not optimal
Both QF and QV rely on verifying identity, so that would be counted as one donation of $10,000. The entire point is letting numbers of people balance in some way against amounts of money, so allowing one person to count multiple times breaks the system
timerol··on I'm Wirecutter's water-quality expert. I don't filter my water
> I hated my pitcher filter long before I knew I didn’t need it. It would clog up any time a bit of rusty water came through the pipes, which, in a 70-year-old building with cast-iron service lines, was often.

I'm a little confused that this is used as an argument against filtering water. I get that iron is not a particularly worrisome contaminant, but I still don't want the occasional "bit of rusty water" showing up in my glass

timerol··on IRS Direct File on GitHub
Who among us has not accidentally made a new repo as just a submodule pointer instead of actually committing the files? https://github.com/IRS-Public/direct-file/commit/2f3ebd66932...

It's also fun that, because this is from the US, they can't just use CC0, but instead need to clarify that this must be public domain, separately from the worldwide CC0.

timerol··on The scientific “unit” we call the decibel
> multiplier for some known value of some known quantity

Of course, unless it's a multiplier for an unknown value of a known quantity, like every amplifier, filter, and sensor specified in dB.

> For instance, in the case of loudness of noise to human ears in air, the unit can be taken to be dBA

Unless you're using dBB or dBC, but of course we all know exactly why you'd use dBC (more suitable for figuring out safety of high impulse, short events) or dBB (it's somewhere in between - you'll know it when you see it).

> The apparent excessive complexity is necessary, not invented to create confusion.

Wait, so writing dB instead of dBA is now necessary, not just convenient?

timerol··on The scientific “unit” we call the decibel
The one thing that really resonates with me from this article is also the silliest thing: Why decibels instead of bels? Everyone has multiplied in scientific notation before, and making a power ratio of 10^4 = 4 B would be so much more intuitive for conversion to absolute figures. It's a completely silly complaint, given that it's literally just a decimal point instead of a d, but it would make mental math of absolute conversions that much faster, especially for people who don't live and breathe amplifier chains all day.

I want to live in a world where a radio can be specified as a -10.2 Bm sensitivity. -9 is three SI prefixes down from 1 mW, so less than 0.1 pW.

timerol··on The scientific “unit” we call the decibel
> 2 mW / 1 mW = 2 = 10^(3/10) = 3 dBm

It's worth noting that this is wrong, in exactly the way that makes decibels confusing. 3 dBm is an absolute power figure (about 2 mW). 2 mW / 1 mW is a ratio of 2 (about 3 dB).

2 mW / 1 mW = 2 = 10^(3/10) = 3 dB.

2 mW = 2 * 1 mW = 10^(3/10) * 1 mW = 3 dB (1 mW) = 3 dBm.

timerol··on Uber to introduce fixed-route shuttles in major US cities

The only thing I know about Kyiv's transit is one tweet (https://twitter.com/threestationsq/status/157216317306670694...), and that makes me confident that it has better transit than any US city other than possibly NYC.

timerol··on U.S. Economy Contracts at 0.3% Rate in First Quarter
They do subtract as an accounting identity, but reasoning from that makes no sense. My net income can be calculated as how much I consume plus my net savings. I = C + NS. So withdrawing from savings "subtracts from net income" in the same sense - ie, it has no explanatory power. If I do a home remodel, spending a bunch of saved up money, the way to understand that situation is not "my income would have been higher if I had not withdrawn from savings".

Importing into inventories counts as both investment and import, resulting in no net change to GDP. Consumers importing for themselves counts as both import and consumption, resulting in no net change to GDP

... I didn't even notice the name. That site is an archive of a collection of textbooks that were Creative Commons-licensed before 2012, dedicated to the memory of Aaron Swartz. Evidently https://2012books.lardbucket.org/books/beginning-economic-an... goes to the same place.

I feel like I just got pranked by SEO somehow

Alas, the government provides no transparency into these calculations. What can a concerned citizen do, other than say "I don't believe"?
