sacnoradhq··on CDC on depression and mortality: wealth, smoking, exercise reduce risk of death
There's a lack of nosological classification of meaningful sub-types of depression and their specific dysfunctions. It's currently scatter-gun, medieval treatments without bothering to measure or understand the systems affected.
sacnoradhq··on Microsoft in talks to sign on Amazon as customer in $1B cloud tools deal
From the comments as of writing, few read between the lines of this sloppy reporting: it's to standardize cloud-desktop apps for Amazon's internal use.

Meta, for example, consolidated to Workplace + Google, away from Dropbox, Microsoft, Apple, and others. They use AWS and Azure for some 50k desktops on demand and a few servers, but it mostly deploys to its own metal because it's way, way cheaper than AWS in most use-cases.

The city of Austin is floating legislation to allow up to 3 housing units per property including campers, RVs, and tiny homes.
sacnoradhq··on *(char*)0 = 0; – What does the C++ programmer intend with this code? [video]
Find me one contemporary example (ANSI C) with a disassembled screenshot.

This is writing sizeof(char) (== 1 almost everywhere) zero to address zero. It is not using a NULL macro or other predefined symbol.

In the real world, this would generally write a byte to address 0000:0000, leading to UB because it would fuck up the divide-by-zero IV.

PS: I used Borland C++ 3.1, Microsoft C++ 3.x and 4.5x, Watcom, and early GNU.

sacnoradhq··on *(char*)0 = 0; – What does the C++ programmer intend with this code? [video]
This statement would be technically legal on its own in x86 real mode if the compiler didn't do null pointer checks. However it would set the divide-by-zero IRQ handler to itself 0000:0000, and when the next division by zero happened, the machine run into UB (likely a reset or halt) because it would jump there, do 4x ADD byte ptr [BX + SI], AL (or ADD byte ptr [EAX], AL) followed by running the remaining interrupt vectors as instructions.

sacnoradhq··on You might be building a PaaS
If you're not building a PaaS while running stuff, you should either rent or build a platform because having a reusable platform enables scalability and manageability.

And if you have 750+ employees, you better have an (endpoint) client platform too to minify development, non-development, and support variables.

sacnoradhq··on Small business owners say they're pressured to hire off-duty cops for security
The Target here in ATX next to downtown hired 2 ex-PMC's in full plate carriers. (APD's call backlog for nonviolent reports runs 36- to 48-hours, so it might as well be never. A private person must then either be equipped to defend themselves, cease venturing in public, or move because the police may be too busy or too unconcerned elsewhere.)
sacnoradhq··on Many Climate 'Solutions' Are Dead Ends or Niches and Should Be Ignored
95% correct. "Planting a lot of trees" has been proven dead wrong because of simple math, plant matter decay, and increasing fucking forest fires. Instead, #teamtrees couldn't face reality while doing the disservice of misinforming and lying to millions of people for egotistical and aspirational post-factual rhetoric. https://youtu.be/gqht2bIQXIY
sacnoradhq··on The Existential Risk of AGI
In this time period, there are many people who are eager to cause mass suffering, murder, sabotage, and dissolution of civilization. With advances in technological organization, there is an increasing potential for coordinated autonomous attacks against infrastructure, essential services, groups, and individual persons in multiple theaters concurrently.

It would be neigh impossible to defend against 100k flying drones wielding cow-knockers programmed to swarm, loiter, break windows, and kill humans. Such could be dispensed by purpose-built intermodal containers, moved by ordinary freight logistics to attack multiple population centers in a simultaneous attack.

Code and binaries are shipped to 10's of millions of servers by internal configuration management tools. Take Meta, Google, or Microsoft and turn them into AI exploit and worm fabrication at scale. While it may happen for only an hour or 2, there's quite a bit that could happen and the possibility of advanced persistent threats is real.

Target a demographic to alter their filter bubble to persuade them to engage in mass-casualty terrorism.

sacnoradhq··on Jupe: Off-grid shelters that pop up anywhere on Earth
The median population center of America is around Indiana, so the average delivery charge will be ~3k. The total delivered cost with tax will be about 30k.

Also, there is a threat of municipalities, including states, suing the manufacturer for selling manufactured homes that aren't up to code. While the cases may lack standing or merit, they have lawyers who can make it very expensive to stay in business regardless.

My '85 VW Westfalia poptop camper is still cheaper than that by acquisition price.

(Not so cheap after solar, remodeling, restoration, and engine swap.)

sacnoradhq··on Jupe: Off-grid shelters that pop up anywhere on Earth
That's immediately what I thought. Plus, there is no absolutely no way this will withstand a 70 mph windstorm while you can fold a travel trailer down in a reasonable amount of time. It's not a secure, real, permanent shelter that conforms to building codes: it's an illusionary shortcut.

These aren't ideal as they look fairly permanent. I don't see the labor or a time-lapse video of assembly or takedown.
sacnoradhq··on Jupe: Off-grid shelters that pop up anywhere on Earth
Risking sounding like Mr. Wonderful: I can't tell if it's aspirational, pre-product marketing or a parody. If it wasn't a joke, then they've just reinvented the travel trailer without the convenience or the trailer. My conclusion then is that it's an elaborate trolling.
sacnoradhq··on Jupe: Off-grid shelters that pop up anywhere on Earth
Although not homeless per se, I lived in a 80's VW Westfalia along the curbs of Silicon Valley for 9 years without A/C. It had a solar panel and I didn't have to buy anything except to keep fragile West German engineering going. The problem is most Americans aren't willing or able to exchange space and comforts, voluntarily or involuntarily, for alternative approaches. Compounding this is most Americans don't have any savings at all and are living paycheck-to-paycheck. If they had funds then they would have an opportunity to use their imagination and lives differently, but too many are on the debt, expenses, and insufficient wages treadmills that may seem all but impossible to escape.

Getting to it and making a living between it and elsewhere is the problem. (Most American's aren't office workers.)

Also, much of the land isn't exactly ideal due to hazards.[0]

Furthermore, being 10+ miles from a serious hospital is a threat to life.

sacnoradhq··on Examining the silicon dies of the Intel 386 processor
Ah, the days of cubicles. Trimble Nav in Sunnyvale had medium-height, solid fabric-backed 6x8' and 8x8' cubicles in 2000. And it was nice to be tucked in a quiet corner of the building by the foosball table room before there was such thing as startup culture. Was almost detained by SGI security by Shoreline Amphitheater (near the 'plex now) doing field radio testing off a coworker's truck that looked like Van Eck phreaking equipment. I should've worn a hi-vis vest. ;D

PS: Raise a paw if you remember the rainbow Apple logo on the triangle building along 280.

> "If management had known that we were using a tool by some grad student as the key part of the methodology, they would never have let us use it."

This is why managers shouldn't micromanage technical decisions.

sacnoradhq··on Words that deserve wider use
The problem with that statement is variance in taste, education, and ambiguity in the real world. Stephen King is making the classic mistake of an introvert projecting a blanket statement based on the mistaken pretense of a uniform vocabulary. There is no such thing. Average Americans have a vocab is about ~43k words, but they aren't the same subset of words or the same number. Furthermore, the vocabular size of the individual is variable up to a 99.99% confidence upper limit that stretches to around 200k.

Although it's fairly certain most Americans won't understand "cyberdisinhibitionism", "consanguineous", "antidisestablishmentarianism", or "insouciance" without additional context, some people's "~50k innate concepts" can receive an adjuvant through performative, logorrheic elucidation. The idiom "a word to the wise" implies the property that sharper instruments require less explanation to make the connection, while most others need a little more assistance.

And there are multilingual people who engage in loaning and coining words. Furthermore, the question of counting colloquialisms like "hangry" muddies the water.

So there is no clever rule except to write to the anticipated audience be it a PhD dissertation in cosmology, an article for "The Atlantic", or a children's bedtime stories for 8-year-olds.

The fallacy is that they are "necessary" when they are entirely elective and a conscious or unconscious choice. There's always a choice that doesn't involve a Hobson's choice.

sacnoradhq··on Jesus nut
It's surprising most rotor mast designs don't include a nested secondary nut and don't use lockwire.

In Japan, motorcycle racing requires lockwire on almost everything. It's a shame helicopter safety engineering generally doesn't meet this basic standard. Although, in fairness, relying on a single spinny thing without an all operational envelope survival passive glide capability is itself inherently dangerous.

sacnoradhq··on USB inventor explains why the connector was not designed to be reversible (2019)
Backwards rationalization / cognitive dissonance for a poor engineering tradeoff.

The cost of zillions of the same panel mount connector will converge to dirt cheap. Although cents matter, user experience matters more if everyone hates your craptastic cheap design. Thankfully, Apple came along and gave the world USB-C which simply increased the bandwidth and current with the convenience of rotational symmetry. A USB-C panel-mount connector costs $0.492 in bulk. Fancy rugged and waterproof ones are $2.18. Micro USB B costs $0.45 in bulk. 10% increase in cost: big whoop for everything except Arduinos and portable kids' night lights.

sacnoradhq··on Lenovo exec promises 80% of its devices will be consumer-repairable by 2025
Ouch. Forget that. I had on-site repair with parts for 3 years. Had one repair during COVID due to a blown charging circuit. They had it for a month and replaced it.

Out of warranty, I stocked up on parts from AliExpress. Need a spare CPU fan? I think I have 6. ;@]
