president_zippy··on Armed police swarm student after AI mistakes bag of Doritos for a weapon
"In your lifetime, there will be more dead kids from bad AI/police combinations than <some cause of death we all think is too high>."

Maybe, but that won't stop the kind of people that watch cable news from saying "if it stops one crime" or "if it saves one life".

That's one of the factors I analyzed in my dinky little post-bacc night school undergrad assignment. The answer I came to is "insufficient data" because none of the longitudinal studies bother with people over 65, which is the interesting part.

My high school XC coach, for example retired 2 years after I graduated in his 60s (before quitting the team because he loved running too much to be a 250lb offensive lineman) and is still running 24 hour runs and multi-day 500k races well into his late 70s without any semblance of knee problem.

Although he played D2-level football in the 1960s, I wouldn't consider him a genetic aberration immune to commonplace orthopedic conditions like arthritis, bone bruises, or stress fractures.

After a few years of not running, I also let myself go and ended up getting passed in a 5k by an 80 year-old woman about a decade ago. I have seen something with my eyes that flies in the face of the "running is bad for your knees" mind virus, and it would be interesting to discuss if there were any longitudinal studies for people old enough to draw Social Security. I don't even think ultramarathon running is worse for your knees than being >200lbs, but I can't find the data that I think should be required before an orthopedist gives any advice one way or another.

I admittedly came into the assignment with an agenda because I thought the "most people should not run because knees" myth was created by people who don't run to deny personal responsibility for their health and discourage other people from believing they can improve their lives if they work for it.

Note: offensive linemen were a lot smaller prior to about 1985 than the 310lb behemoths out there today. If you like football, thank Lawrence Taylor for that evolution in the game.

It's funny you just mentioned this because we just learned a few weeks ago in physiology about Henneman's Size Principle: that the somatic nervous system recruits smaller skeletal muscle motor units (1) followed by larger motor units as the amount of force needed increases.

That would make resistance training by rowing in water better fit than some magnetic resistance machine based on what you described. Air also has same property like any other fluid, your average big body of water has enough viscosity for this property to matter at speeds we don't need cybernetics and Tommy John's surgery to survive.

(1) A motor unit is just all the muscle fibers controlled by 1 motor neuron. With this single source of signals, all those muscle fibers respond the same way.

When you put it that way, I think whether culture is upstream of business or vice versa and whether people have free will or are merely conduits for things their senses receive are unanswerable questions. All I know is this:

"If you treat people as they are, they will become worse. If you treat them as they could be, they will become better.

If we treat people as if they were what they ought to be, we help them become what they are capable of becoming."

-Johann Wolfgang von Goethe, Wilhelm Meister’s Apprenticeship

I'm convinced that treating most people as if they have free will is more likely to get them to at least consider my ways.

I think I get what you're implying. As long as the router itself with its firewall + DNS + NAT, is secure from attacks by actors over there internet, the access point I will connect to it only needs to be secure against people within 100 feet of it.

My only concern here is configuring an access point to just be a dumb antenna that xmits/recvs and AES encrypts/decrypts ethernet packets from a handful of MAC addresses without doing NAT or any other additional processing of those packets. The concerns my OpenBSD buddies have about the software on ASUS routers is well-founded, but I don't think any of us is sufficiently versed in layer 2 security.

What's the extent of your expertise in layer 2? I would rest easy as long as my router and access point are not willy-nilly giving away my MAC addresses to fine institutions like this place.

Other than DCS, Skyrim, and that one Star Wars game at Dave and Buster's where you duel Darth Vader, I don't see a lot that sings to me just yet. Granted, I could easily get 2,000 hours out of DCS over the span of a decade just flying every third and fourth generation fighter jet ever made.

Maybe VR doesn't need that many games because the small handful of good ones have so much depth and replay value. I guess I just talked myself into a $700 VR kit and possibly a $700 GPU upgrade, depending on whether or not my RTX 3060 is up to task.

It was definitely useful and appreciated on the "New" Nintendo 3DS XL, which also used a camera to track your eye movements and adjust the divergence accordingly. I hate the fact that Nintendo abandoned this technology because experiencing Ocarina of Time and Star Fox 64 in 3D was world-changing to me.

I'd say I'm not the only one who misses this technology in games, because a used New 3DS XL costs at least $200 on eBay right now, which is more than what I paid new.

I always thought 3D would combine really nicely with a ray traced graphics full of bright colors and reflections, similar to all those ray tracing demos with dozens of glossy marbles.

But was the eulogy written in Perl poetry? I see it everywhere, but I don't know who this JAPH guy is. It's a strange way of spelling Jeff, and it's odd that he types his name in all caps, but he has published a remarkable quantity of works and he's even more famous than the anonymous hacker known as 4chan.

I just had a flashback to the heyday of MySpace. Now that I think about it though, Neocities has the "social networking" of being able to discover other people's pages and give each other likes and comments.

Hmmm...

president_zippy··on Sodium-ion batteries have started to appear in cars and home storage
Are there any better sources we should read for how and why sodium-ion batteries are better than lithium-ion batteries?

All I know is that the charge to mass ratio of an Na+ ion is less than that of an Li+ ion, and that elemental Na and Li are both highly-reactive with violent exothermic reactions when exposed to water. I need someone with chemistry or materials science experience to help me explain what the advantages are and how those advantages exist.

I saw the follow-up responses complaining about you soliciting, but I've got no problem with you offering to solve a problem and being remunerated for it.

However, my lab is a brokedick operation with barely enough cash reserves to pay staff salaries. We sincerely do not have the budget to buy new software, especially after the NIH funding cuts.

president_zippy··on OpenBSD 7.8
If I had a nickel for every time my OpenBSD buddies told me "your ASUS router is not secure, just configure an OpenBSD machine as your router", I'd have a lot of nickels.

The part they never tell me is what hardware they recommend for the Wi-Fi, or rather which devices have OpenBSD driver support and allow for at least 4-5 good connections over 802.11ac?

I'm all for it, I just don't know where to start on the hardware.

I don't thing we fundamentally disagree on anything, I'm just saying every product advertisement tries to convince you the product will make you happier, and sometimes it not a bad thing- like Japanese McDonald's (where they don't use hydrogenated oils).

All advertising is based around creating a need and fulfilling it, but not all of those needs are toxic. Imagine getting an advertisement for a concert for some musicians you've never even heard of. You hear their music, and maybe they even have some showmanship. You like what you see and hear, and now you have a need you didn't have before, whether that's going to a KISS concert or whatever kinda music floats your boat.

Toxic ads encouraging you to indulge in toxic behavior, like an Instagram ad making you think you don't matter if you don't publicize every hour of your life, are a different animal.

That's all I'm trying to say, I'm not trying to be pedantic or anything. I just don't think putting out a Disney World ad of a happy family eating breakfast with Mickey Mouse is promoting or exploiting toxic values even though it convinces you that you need something you weren't aware of yesterday.

president_zippy··on OpenBSD 7.8
You did a lot of cool things, mister. How do I send you pizza (from one of the good places)?

Glad to see how many high-value changes OpenBSD is receiving. You just inspired me to get Chicago95 up and running on an old MacBook I have lying around right now, and replace the battery. I run it off of an old Lenovo Thinkcentre that I use as a server on my local network, but I haven't been using it as my daily driver. The number of things I can run on macOS is a lot smaller than it used to be 15 years ago, so I might give OpenBSD another shot as my daily driver.

P.S. I didn't know there were other people interested in using Chicago95 on OpenBSD, let alone OpenBSD contributors. Good stuff, man!

Illinois and Massachusetts are definitely not slashing public school spending. Deep-red Florida is also increasing its educational budget, and so is deep-red Texas.

It's not like I have family or friends with kids going to public school or anything in those states, what do I know?

I'm impressed that they still maintain PA-RISC support even though HP discontinued that architecture in 2008.

They maintain all these architectures in such a small, consolidated codebase with such minimal (if any) bloat.

Their built-in httpd is far and away the best experience I ever had setting up a static file server for my local network, and I can't think of many times where I would ever need anything I couldn't do with the built-in FastCGI support.

I'm also pleasantly surprised by how well Chicago95 (a Windows 95-style UI based on xfce) works on OpenBSD, even though the author never intended to run it on anything but xubuntu. I wouldn't recommend trying that unless you're willing to roll up your sleeves, but the payoff definitely justifies the elbow grease if you like that look and feel better than xenodm, XFCE, or GNOME.

When you can't make a point, just resort to name calling and tone policing.

I'm definitely on point that most teachers in blue states have worker protections, job security, and lax hours that no software engineer has despite comparatively low pay. In Illinois, the top end of high school teacher salaries even crosses into six figures.

I can't recall one software engineering job with tenure, let alone tenure that vests after 5-7 years.

I also can't recall one software engineering job listing with a benefits package that has the same vacation as a child and civil servant-grade health insurance, but maybe I'm looking in the wrong place. If you find a job posting like that, let me know.

If parents still spanked their children, it would be the best semi-retirement gig a person can get.

I don't think that kind of advertising is directly advertising happiness. Luxury car ads advertise status more than anything. They're more subtle about it than Equinox gym marketing with its weird, sexualized elf people, but the product they're really selling you is being better than your peers.

My first instinct is that the Google interviewers were just so full of themselves that they think they're doing you a favor and would do it to anybody, regardless of gender.

If I were turned down for a job that involved writing FreeBSD kernel code and the hiring manager gave me a free book on FreeBSD kernel programming, I'd think they were cool people and try again in 18-24 months.

It's not the act of giving a a rejected candidate a textbook, the insult is that it was a supplemental text book for the very first CS class most undergrads take.

Going back to the interviewers, there are going to be jerks in any organization with more than 20 employees, but the fact that their culture sees this kind of patronizing behavior as "saving the world" and "making a difference" is a red flag for me.

I don't think you understand the fundamental difference in motivation between you and most of us here. Most people here would rather be the CEO of a garage with a couple computers than an SVP at Amazon. Nobody needs Amazon to have a door desk.

Do you know why? It's because most programmers don't like being told what to do, let alone by people who are not programmers. Most people around here DESPISE corporate HR, and Amazon has it in spades.

As for the pyramid scheme comment, my reasoning is not only sound; it's Puget sound...

Amazon entices new grad hires with RSUs on a backloaded vesting schedule and then fires them very shortly before the vesting cliff. If "they should have read the fine print" is Amazon values, I think you need a new set of values.

president_zippy··on Today is when the Amazon brain drain sent AWS down the spout
Yeah, but I didn't have to work at Amazon to do it. No micromanagement, no verbal abuse, no work calls at 3am, no PIPs, no door desks, no cult indoctrination.

More importantly, the time I spent managing my portfolio taught me how to better manage my portfolio. If Elon Musk or Jeff Bezos is richer than Warren Buffett or Peter Lynch, it does not change the fact that Warren Buffett and Peter Lynchs' path to success is much more reproducible and reliable with a much lower barrier to entry.

If you made that kind of money working for Amazon, then good for you. I wish more members of the middle class would make FU money and save their money so they can hold greater leverage and take home a much larger portion of the value they add to society.

"The man who gives me employment, which I must have or suffer, that man is my master, let me call him what I will."

-Henry George

P.S. FWIW, I don't need that much to be happy. Last March, I visited my wife (then fiancee) in Hiroshima and spent 3 weeks in a 250sqft weekly-rental apartment in sharing a twin bed, living off of Ogura toast and miso soup for breakfast, < $5 meals at Ramen and Udon shops, making Katsu curry together, and going on walks, and it was the best time in my entire life.

Pardon me if you thought I was trying to convince you I'm rich or humblebrag about it. Far from it, I'm just finally financially independent and happy about it. I never wanted to be rich, just rich enough to say "fuck you" to growing someone else's grapes and pressing someone else's wine so that someone else can wear fine silk.

I achieved my goal of no longer needing to be a software engineer to maintain a lower middle class life. That's all.

Evidently, I'm just imagining all the times my teachers went on strike in Illinois in the 2000s. There have not been any "right to work" laws in Illinois passed affecting teachers or firefighters since then. Evidently, it's all in my head that most blue states like IL, MN, MA, and NY have legal protections for public schoolteachers.

I never said I was opposed to it, either. Quite the contrary. In fact, I think public schoolteachers and firefighters have a great idea about unions, and software engineers should follow their example and unionize.

I can't tell if you're honestly misguided or if you're an HR employee at Amazon trying to derail the thread, because you completely missed my point. I don't care who has it worse. I care about who is making it bad, and what we as software engineers are going to do to make it right.

Where in all of this discussion did I say anything about California?
president_zippy··on 60k kids have avoided peanut allergies due to 2015 advice, study finds
I'll give you the principled answer and the cop-out answer. Here's the principled answer:

That was just the catchy title, similar to peer-reviewed literature reviews published on nih.gov: not necessarily the creme-de-la-creme, just good enough to pass peer review. I real question is whether concern for cartilage erosion is well-founded, and whether or not it outweighs the scientific consensus that running improves bone density of the tibia and fibula. Again, literature had strong evidence for the latter while the former was still a major controversy in kinesiology.

I didn't even touch cardiovascular health, because to be fair we live in a world with bicycles and affordable YMCA lap pools.

Here's the cop-out answer: It's a literature review- the very requirements are merely one step removed from those blog articles Harvard Medicine publishes for mass-consumption. I followed instructions, one of which was to adhere to a maximum of 2 1/2 pages, and I got a Northwestern 95 on the assignment.

president_zippy··on When Compiler Optimizations Hurt Performance
The one that really blows me away is how KazeEmmanuar explained the software-controlled cache. Using it well would involve either manually making calls to load/invalidate it or writing a compiler backend that replaces loading data from memory into registers with instructions to load specific memory address ranges into cache.

The whole thing reminds me in a fuzzy way that I don't yet fully comprehend of register-memory architecture.

What about just accepting the job, faking a medical problem that requires extended time away from work not to keep the paycheck, but just to officially remain on staff for the purposes of future background checks, and meanwhile apply to other companies. You could just take an unpaid extended medical leave for cancer treatment and bribe an MD to make a phony "sick note" similar to playing hookey back in grade school.

You wouldn't be defrauding anybody if you're not getting paid. You could take a sabbatical for 6-9 months and tell better companies you were working for Amazon that whole time.

president_zippy··on When Compiler Optimizations Hurt Performance
If you wanna really see this at work on a whole other extreme, try compiling code for an N64 game. It's no surprise that optimizations for modern-day x86_64 and Arm64 processors with a lot of cache would not generalize well to a MIPS CPU with a cache that must be manipulated at the software layer and abysmal RDRAM latency, but the exact mechanics of it are interesting.

KazeEmmanuar did a great job analyzing exactly this so we don't have to!

I guess I just assumed teachers have the same protections in deep blue Washington state that they have in Illinois and Minnesota.

If I'm wrong, I'm wrong. However, there's a fix for that: move to a state where the job prospects are better. That sounds like "let them eat cake", except that moving to another state as an American citizen is a lot easier than what of people went through fleeing the Sicilian Mafia or the Irish Potato Famine, let alone WW2 European front or the fall of Saigon.
