abnry··on What we know about CEO shooting suspect
> But I don’t think it’s hyperbole to consider the actions of this CEO and his company in the same breath as such evil tyrants

But it is. Tyrants round up women and children and execute them. Healthcare is more complicated because you have multiple causes at play: the health conditions of patients, the hospitals and what they bill, and the insurance companies.

Money is a big factor here. People talk as if insurance companies should spend unlimited resources on every person. I understand the resentment over wealth inequality, but someone recently calculated that the top 4 billionaires could only support healthcare for everyone for 3 months. Money is not an infinite resource. Rationing is unavoidable.

But I get that there is a problem. Automatic denials and denials over treatments that have clear and significant benefits are a problem, absolutely. And the system could run more efficiently. But we also can't avoid death due to old age or sickness. Nor painless death.

But we can avoid murdering people in the streets in cold blood.

abnry··on What we know about CEO shooting suspect
See, you put the caveat at the bottom, but I think you are just having a normal discussion. You aren't speaking "very confidently," you are just making an argument.

What I think happens is people who are very knowledgeable about a subject are hyper-sensitive to slightly incorrect information. And to boost their egos they like to diminish the people making the incorrect statements as not just incorrect, but confidently incorrect, a la Dunning Kruger.

See how confidently I made the exaggerative statement above? I don't necessarily mean it to be completely true, but I am making an argument. I think an assessment of confidence requires more than seeing no mollifying qualifiers like "I think" or "it might be". There's no verbal tone on the web.

abnry··on United Health CEO Decries "Aggressive" Media Coverage in Leaked Recording
This week I have learned that murder, not justice, is wildly more popular than I thought.
abnry··on Show HN: I made an ls alternative for my personal use
> I barely ever even use the -la options.

Certainly I use these less than plain "ls," but digging through hidden files and folders and looking at timestamps is very important for me.

How viable is Asani Linux these days? MacBook hardware looks amazing.

abnry··on NewPipe on Linux, Using Android_translation_layer
I know a lot of people hate on the recommendations homepage on YouTube, but I discover a lot of content I like watching there. However, I can't watch all of it and what to save what I see there and otherwise find and search for in a playlist, but the watch later playlist is not user friendly. Does Freetube improve playlist management too? That would be a big plus.
abnry··on Sinusoidal Sunlight
I don't think there will ever be an answer to this. There's a similar problem with choosing a threshold for a decision. The common thing to do is to make a RoC curve to compare the trade-off between true positive rate and false positive rate.

If you have a system you can reason about completely, then sometimes you have a number that gives the absolute answer. Say you get error below floating point resolution.

But I guess it's otherwise what is perceptible or meaningful, either in quantity or percentage. A penny is not a life changing amount of money and something happening 0.01% of the time is rare enough to be tolerable.

abnry··on Rip2 – A safer, rust-based rm
That's not true. rm is a known foot gun and commands like trash-cli already exist.
abnry··on Project Euler
I have great memories of competing with a college friend to solve these problems. Since I last seriously did the problems, probably 15 years ago, they have added a lot more.
abnry··on Why does FM sound better than AM?
In this analogy, the AM and FM signals you receive aren't usually experiencing interference, they are experiencing multipath effects which includes things like path loss, attenuation, reflections, and so on. This is driven by geometry. You also have gaussian noise that the receiver has to deal with.

You model this by taking your signal and convolving it with the channel vector. Usually the channel vector is a finite number of dirac deltas. Each delta is a different reflection. They are like echos. They can cause the signal to constructively and desconstructively interfere with itself.

I haven't seen the math, but I am guessing this doesn't do as much to the frequency of the signal compared to the amplitude.

abnry··on Fraud, So Much Fraud
I have always said that while professors get paid less money than in industry, they are compensated in reputation to make up for it. Status and reputation are the currency of academia.
abnry··on Linux Horror Stories and Protection Spells (Volume I) (2021)
I do the same. My alias for rm just echos "use trash" so I don't replace its function, just disable it.

When I really need to use rm I type /bin/rm.

abnry··on How America's universities became debt factories
Re: 4), isn't forgiving loans awfully close to having power of the purse? That is explicitly congress's role.

You have some really perverse incentives too if you allow loan forgiveness by the executive branch, something close to buying votes.

abnry··on Falsehoods programmers believe about TCP
My only guess how this could make sense is if there is some ambiguity in the definition of a TCP packet.
abnry··on Nobody Cares About Security
I think man in the middle attacks are the concern. But still better than plaintext.
abnry··on The Internet Archive has lost its appeal in Hachette vs. Internet Archive
I mean, many authors do care about their copyright. So if you disregard copyright en mass, then yeah, you are against the people writing the books who care about their copyright.

You could have made a fairer point if the IA only disregarded the copyright of authors who are dead or something like 10 years past publication.

abnry··on Systemd, 10 years later: a historical and technical retrospective (2020)
I still haven't fully grasped the Systemd drama, or systemd for that matter, but boy do I love it. I enjoy how Linux has those turf wars nobody outside of it knows about.
abnry··on DB Browser for SQLite (Windows, macOS, and Most Versions of Linux)
I appreciate this software, thanks!
abnry··on Teaching general problem-solving skills is not a substitute for teaching math [pdf] (2010)
Aside from that, understanding counterexamples teaches you to understand the definitions and theorems better. Which matters for proving future results.
abnry··on AI Photo Geolocation
I took images directly from Google Images search and it got them wrong. But it was sort of directionally right. My local city hall it said was the courthouse in the same county. The local bridge was put into a wrong state.

Interestingly, it provided reference images and the images I posted were basically in the reference images.

abnry··on A canonical Hamiltonian formulation of the Navier–Stokes problem
I have no clue about this paper. Only comment is that this was published April 1st.
abnry··on Suspicious discontinuities (2020)
Another place this shows up is in online chess ratings.

See Lichess: https://lichess.org/stat/rating/distribution/blitz

Couldn't find this in Chess.com stats, but maybe they do some smoothing in their plot.

abnry··on Family Dollar to close almost 1,000 stores
> The thing I don't like about these stores is IMO they take advantage of poor people who think they are getting cheaper products

This only makes sense if you think poor people are dumb or naive. They don't know how to compare prices?

As other people have mentioned, sometimes the value is the amount you can buy. If your personal financial margins are small, it is okay to spend more per oz on a single bar of soap because it is the difference between having soap vs not.

We shouldn't assume cost per unit is the only value a store provides.

abnry··on Feds want to ban the Flipper Zero – Experts say it's a scapegoat
From what I understand, it is magical in the sense that it makes everything easy to do, even for people without much knowledge.

If you know F=ma, p=mv, and by calculus that a=v', all of which is high school level, then the time derivative of momentum is clearly force.
abnry··on What is the difference between a terminal, a shell, a TTY and a console? (2012)
I guess my understanding is that a tty must involve a device driver for an actual piece of hardware. A pty is all software, implemented as a feature of the kernel any application can ask for.
abnry··on What is the difference between a terminal, a shell, a TTY and a console? (2012)
And then there are PTYs or psuedoterminals.

Next thing you know, you're learning how to flash ESP firmware and how Zigbee protocols work.

The cool factor is maybe 25% of it for me. It's mainly an obsessive hobby.

abnry··on America lost the chestnut, its "perfect tree"
"Chestnuts roasting on an open fire Jack Frost nipping at your nose."

I was always struck how nobody roasts chestnuts anymore. Then I learned how some forests in the US had 25% chestnut trees and that blight killed almost all of them. What a fascinating thing that chestnuts were as common as acorns for our grandparents and great-grandparents but are almost non-existent for us.
