mrexroad··on Root cause analysis? You're doing it wrong
I love 5+ why's. I find it to be a fantastic tool in many situations. Unfortunately, when leadership does not reward a culture of learning, Five Why's can become conflated with root cause analysis and just become a directed inquiry for reaching a politically expedient cause. The bigger the fuck up, the more it needs an impartial NTSB-like focus on learning and sharing to avoid them in the future.

Fwiw, if I were your manager performing a root cause analysis, I'd mostly expect my team to be identifying contributing factors within their domain, and then we'd collate and analyze the factors with other respective teams to drill down to the root causes. I'd also have kicked back a doc that was mostly about blaming the other team.

mrexroad··on How hard do you have to hit a chicken to cook it? (2020)
> quick back-of-the-envelope calculation suggests that if your body were doing that much work, your core temperature would reach fatal levels in a matter of seconds.

Disappointed they didn’t factor in other inputs to the propulsion (e.g. battery assist, etc).

mrexroad··on Interstellar Object 3I/Atlas Passed Mars Last Night
> “But based on the researchers’ analyses of the interstellar object’s vertical motion in the galaxy (its path is known to weave up and down in the galactic disk), they concluded that it likely originated from the Milky Way’s thin disk, not its thick disk as was mentioned some months ago. The thin disk contains somewhat younger objects than the thick disk.”
mrexroad··on Interstellar Object 3I/Atlas Passed Mars Last Night
Tangentially, I enjoy reminding my kids how long it takes our star to complete a rotation around the Milky Way, and then also point out that we can go to a museum and see fossils of what life looked like one galactic rotation ago. It gives the right amount of backward and forward perspective about the rock we live on that I want them to keep tucked away in the corner of their mind.

Quite the opposite for me. I’m fascinated and inspired by the fact that this rock escaped the gravity well of one star and is now visiting another.
mrexroad··on Using Cesium-137 testing to find counterfeit wine
> Mobil might add the particles to their premium Mobile 1 synthetic motor oil product to find counterfeit products in certain markets. By opening a bottle of oil purchased off the shelf they can hit it with ~620nm && ~580nm and if it does not respond correctly

Interesting. I haven’t heard they had additives in the oil to detect counterfeits. I assume the fluorescing behaves differently at 620nm and 580nm? I recall they had issues with counterfeits in some countries and have made attempts to combat it with packaging (e.g. specific letters on label fluorescing under UV, and currently their Scantrust app [0] validation tool). I’d be interested to know how it behaves, as having the oil itself fluoresce when not labeled as such might be annoying when using UV dyes for monitoring leaks. For example, I like to run LiquiMoly’s molygen every few changes to monitor changes in seeping on one of my older cars, but it is only helpful when i run the oil w/ dye after non-dyed oil.

mrexroad··on Why your outdoorsy friend suddenly has a gummy bear power bank
sleeping.

my thermarest pad is a decade+ old and I won't hesitate to take it on a lengthy backpacking trip as long as I have a patch kit, same as a bike tire.

mrexroad··on Robert Redford has died
Thanks for the rec! Will check it out. While a bit of a general bend (and not Robert Redford), I also felt Andor was a terrific portrayal of spycraft— the asset recruiting/handling, opsec, counter intelligence, etc.—and would still hold up equally well if extracted from SW and dropped into a contemporary setting.
mrexroad··on Apple Photos app corrupts images
Just a nit — your post would have been fine without that last sentence, no need to be prickly. I haven’t touched RoR in 15 years and was not familiar with the name.
mrexroad··on Robert Redford has died
“Spy Game” is one of be one of the best spy films I’ve seen in terms of recruiting and handling assets.
mrexroad··on macOS Tahoe
I’ve settled on swiping up on the (…) button. But yeah, either way I’m bummed that usability had been traded for shiny/trendy aesthetics here. Worst part is that they know and have provided options to have “classic view”/“try new ui” rather than iterating and polishing it to the point it’s substantially improved and there’s no choice but to release it.

Design is a series of decisions. Those decisions should be rooted in a strong, thoughtful, point of view. It’s a problem when the final product embodies multiple points of view; view options should be the extreme exception, not the norm we now see in phone, mail, safari, etc.

mrexroad··on Ghost kitchens are dying
Restaurants / cafes in Japan have less fixed cost overhead than in the US. Zoning, licensing, insuring, etc. in Japan are more conductive to small shops being able to stay afloat with only moderate business. There’s other factors of course, but those are biggest ones I found when exploring potential for small side project. With that said, I have yet to run a bar/cafe in either country, so my experience is limited to my research.
mrexroad··on How big a solar battery do I need to store all my home's electricity?
Yeah, w/o grid fallback, I’d much rather aim for 98-99% w/ solar and have an alternate source to close gap, rather than aim for “five 9s” on solar+batt. It’d take a lot to talk me out of a multi-source approach.

Sorry, can you clarify where it’s stated they were illegally imported / trafficked?
mrexroad··on WiFi signals can measure heart rate
Boomer was being investigated one of the first episodes for leaving the hatch to the water storage/recycling unlocked, where explosives were then detonated. Maybe it was the armory--it's been quite a few years, but close enough for a pun.
mrexroad··on Experimenting with Local LLMs on macOS
They did have Xserve back in the day. As great as Apple silicon is for running local llms along with being a general-purpose computing device, it’s not clear that Apple silicon have enough of a differentiating advantage over a rack of nvidia gpus to make it worthwhile in enterprise…

Thank you for sharing! I knew Nagasaki was alternate selection, but this is first time I’ve heard three runs were attempted before diverting.
mrexroad··on Freeway guardrails are now a favorite target of thieves
Yeah, I’m rather surprised rather they’re AL.

Related: I recently had a few hundred lbs of clean galvanized steel to dispose of and looked into selling to scrap yard. I would have spent more on gas, one way, taking it up there than I’d have gotten for it. Luckily my local recycling yard (2-3mi away) was happy to take it for free. Ironically, I also took a few half-full trash bags of AL cans and got ~$35 for them.

Maybe it’s just a Boomer thing? (Sorry, couldn’t resist the BSG / trek crossover joke).
mrexroad··on Almost anything you give sustained attention to will begin to loop on itself
“Action comes before motivation.”

I’ve repeated this to my kids to the point it’s a meme in our house. I find it’s a nice short circuit to “I have no motivation”, b/c “Great, do {thing} and you’ll find the motivation!”

mrexroad··on We already live in social credit, we just don't call it that
Crime stats, especially for violent crime, are relevant to us, not them. Their wealth, status, and/or insurance policies generally require security details and precautions that insulate most “public” activity from random acts of violent crime. However, the former UHC CEO’s death is an example of the sort of singular, and targeted, crime that does strike fear. However, the comment you’re replying to is alluding to the historical collapses of societies (a.k.a a complex system) where economic inequity exceeds a tipping point leads to system collapse (“heads roll”). “Clamping down on peasants”—social credit, pervasive surveillance, collating movements/associations, uh, Palantir—enables evasion of the tipping point and adds resilience to the system.

Tl;dr: violent crime doesn’t mean anything when you have billions, but instability in the system does. Surveillance state tropes exist for a reason, and that’s b/c they add resiliency to a system that would otherwise collapse.

mrexroad··on Acoustic Panels as Wall Coverings in Star Trek: The Next Generation
I’ve always loved behind the scenes for sci-fi set designs and ship building. Kit bashing, repurposing junk yard items, painted container lid wall plating, etc. always forced me to look and think differently about everyday items. I can’t help but lament the loss of the constraint-drive emergent soul/feel of these “worlds” as CGI backgrounds and/or movie budgets applied to TV series set design (e.g. ST:SNW, ST:PIC, etc). With that said, Andor did show how high budget physical set designs can significantly contribute to world building.

I revisit this chair list every now and then, especially during a rewatch of a series.

Worf’s chair always stood out to me as a life goal when the series aired. I settled for a Stokke high chair for my kid.
