oldbbsnickname··on Kidney stone procedure "has the potential to be game changing"
I have 19 mm left and 14 mm right stones that I generally don't notice and don't have any pain.

ESWL seemed like a scam because there was no redness on back tissue and not a single grain or fragment was passed. I wonder if they set the machine to a high enough power or if they skipped the actual procedure while I was anesthetized.

I'm wondering if BWL would be any better where ESWL fails.

oldbbsnickname··on Brisk 22-minute walk could offset harmful effects of sitting, study suggests
Shit. This is what I need. A point 0.5 mile / 0.8 km away at 3.1 mph / 5 kph.
oldbbsnickname··on Someone is trying to rebuild Friendster
Legend has it that MySpace's purple Comic Sans blinking marquee font, animated star glitter, and ActiveX malware can be heard off in the distance at night on the internet. It's what happens when you give under-filtered HTML and CSS access to users of a social media site that's essentially a CMS.
oldbbsnickname··on Someone is trying to rebuild Friendster
That would be hilarious. It was sold and revamped as a social network in Asia, but I assume worldwide IP rights went with it. I seem to doubt that it could or would be "rebuilt" unless IP rights were retained or conferred legally.

Barcode apps and libraries that render and scan can do the same without consumables.
oldbbsnickname··on Ask HN: PG's 'Do Things That Don't Scale' manual examples?
Cries with the demise of the original Symbol. (It's owned by Zebra now.)

A giant university student housing department changed their FMMS system from Apple Newton MessagePad 130 from Symbol MC50's in the spirt of Barcodes and database for all the things! In that era, I had ~50 unique smart PDA-barcode scanners on my desk.

oldbbsnickname··on Addressing Changes to PfSense Plus Home+Lab
Sadly, pfSense lost me a long time ago.

I'm happily on my 2nd OPNsense business license on Deciso embedded Ryzen-based hardware with 10 GigE optical links. Even takes care of PKI and has 2FA. I'm happy and I don't have to worry about massive, arbitrary license changes or big corporate enshitification.

oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
In Soviet Russia, Gulag break you into rocks.
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
Yep. It's easy to skip the TCO analysis to make it seem like it's "helping" in the context of a study trying to sell another study.

The Bill Gates-associated method of spraying fine lye in a hyperboloid tower seems the most effective, perhaps at a slightly higher pressure of 2-3 atm to both increase the temperature and reactivity. The lye would be produced in a closed carbon cycle process using renewable energy sources.

I would bet seaweed or phytoplankton plus floating farm rigs would readily lead to scalable CCS. A few small regions of Earth's oceans would need to be sacrificed for sequestration.

oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
As long as it's not a Sisyphean task.
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
Exactly. There is little-or-no desire to eliminate animal agriculture despite the obvious data that it is killing us as much as FF private vehicles. There are many luxuries and senses of entitlements that cannot be curtailed politically short of authoritarian decree.
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
It's about scalability of any particular process minimizing net $/t (which includes kWh/t).
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
In general, to be scalable and cheap, CCS needs to be mostly passive activities relying on biology and large surface areas. This would then usually involve farmlands, forests, or oceans. (Not necessarily trees because they lack automatic sequestration.)
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
There don't. The problem is a lack of remote industrial equipment that are EVs powered by renewable electricity sources rather than diesel fuel.
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
> Clearly the solution is... build roads from olivine! :D

Haha. I'm glad you didn't include "solar" or "freakin'". ;D

oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
Clinker manufacturing for cement and concrete is amongst the worst offenders. This can be made greener with closed-loop production and CCS, and there are already efforts nearing or at commercial production with it.
oldbbsnickname··on Adding crushed rock to farmland pulls carbon out of the air
Nit: Confusing units. The proper unit for this field is Gt (Gigatonnes).
oldbbsnickname··on Even the Tesla Cybertruck's Brake Lights Don't Make Sense
California vehicle code (VEH 25251.5.7(a)) has an interesting inclusion of strobing yellow center light proportional to brake force.

What I think is absurd is red, yellow, and/or blue flashing lights except for emergency vehicles on or conveying to an emergency. Throughout the South US, maintenance vehicles flash zillions of lights creating visual distractions and flasher fatigue.

oldbbsnickname··on How to find a lost phone in a no-cell-coverage camping site?
Comcast can die screaming, fiery deaths with rapid reincarnation between them.

The were the only ISP in a certain suburban wooded area. During planned power outages they would go out after ~16 hours because they failed to engineer survivability (choice of electrical circuits and backup power) as the cell phone networks, municipal water, and other critical services did.

oldbbsnickname··on California slams San Francisco for 'egregious' barriers to housing construction
Hey SF leadership, it's only been 12 years... sigh. Do I need to come back down there and demonstrate how I point my index finger in the air? Don't worry, I'm not running for POTUS and using this as an opportunity to throw you under the bus as a political calculus.
oldbbsnickname··on Loyal workers are selectively and ironically targeted for exploitation
Being a worker is being underpaid, to varying degrees. Another way to put it is "the most valuable employee makes the most impact for their salary", so the tendency is to maximize the former and minimize the latter.

"Loyalty" is a manipulation game. The only true loyalty is to #1, but most honest people don't even do that.

One primary way to get ahead is be in-demand, court many offers, and play offers off each other in an ego-respecting manner within whatever the market will bear. Raises rarely happen, so it's usually better to switch jobs every 1.5-3 years.

At some point in a high-income career path, switching jobs doesn't have to be as necessary or desirable, and a lawyer and a TC negotiator can help them get more $$$.

Furthermore, anyone good will have lots of options and should always be open to other homes if only to window shop. (Never be stuck somewhere miserable or without options.)

oldbbsnickname··on Meta Reports Third Quarter 2023 Results
You heard correctly.

Technical teams: There are some pressure-cooker teams where there are micromangers obsessed with counting diff revisions and maximum project impact, a smattering of individuals who are overconfident big fish in small ponds. Most technical teams are normal and helpful. Some are even loosey-goosey and casual. There are a few teams who have no customer service skills or professionalism at all, but those aren't many.

Nontechnical teams: I've observed multiple IRL collections of people who literally go to work to socialize... and do so loudly and not in a conference room. Maybe they do work, but I didn't see any sign of it. Slacking-tolerant areas must have a reporting structure that doesn't have a lot of hard accountability, may not have to produce quantitive impact, and are able to hide in a megacorp when there is sufficient complexity and opacity.

One other thing that ticked me off about IRL Metamates: most volunteers for a home building nonprofit left without coordinating with the site manager, leaving them understaffed for the work and cleanup tasks. It really shows the personal ethics of people who pose for photos for their personal brand but then don't care enough to actually do the work.

oldbbsnickname··on Apple jacks prices to juice profits because $19.3B a quarter isn't enough
That's my point. The trend of the sum of streaming prices + internet all-in with inflation is absurd.
oldbbsnickname··on How to find a lost phone in a no-cell-coverage camping site?
Creating rogue APs is criminal-adjacent, unethical behavior because it denies and interferes with a network. It could even be criminalized in some jurisdictions.
oldbbsnickname··on How to find a lost phone in a no-cell-coverage camping site?
That option can be disabled by turning off "Find My network" such that the phone will be off and radio silent. With it on, it will continue to beacon until the battery reaches the final BMS low voltage point.
oldbbsnickname··on How to find a lost phone in a no-cell-coverage camping site?
Disassemble and remove the battery. I can do this in about 1-2 minutes, others more skilled can do it in <30 seconds.
oldbbsnickname··on How to find a lost phone in a no-cell-coverage camping site?
Not really. The phone only appears "off" but is in-fact in a low power mode providing beacons. It won't work if the battery were removed.

Also, modern iPhones use tower-assisted GNSS (GPS, GLONASS, Galileo, QZSS, BeiDou, and NavIC) so the satellite isn't necessarily Navistar. With fewer or no towers, and positioned in an odd orientation on the ground, a good fix becomes much less likely, and the range can increase from <1m to 10's-100's of m.

oldbbsnickname··on Woman who burned herself on Dunkin' coffee settles for $3M
Unsafe options by default, hence the prevalence of "extra hot" elsewhere.

Maybe it's better to avoid expensive, convenient consumption with single-use waste and get a mug, burr grinder, and K-cup machine with a refillable adapter. ¯\_(ツ)_/¯

US companies tend to lack proactive risk management because the approach to consumer product safety doesn't insist on the precautionary principle and instead focuses on periodic, reactive tort litigation after harm has already occurred, placing the burden of proof on those harmed. This is like the difference between quality control and quality assurance. One tries to fix things upstream to be better overall while the other drops an "Inspected by #42" on anything that isn't obviously unsellable.

oldbbsnickname··on Was Rust Worth It?
Mostly yes and good.

One thing I don't appreciate is nonorthogonality of certain uses and control structures that cannot be refactored into a function despite structural equivalence without introducing a multiple borrow conflict.
