francis_t_catte··on Apple stuck the Mac mini power button on the bottom
the resdesigned USB-C magic mouse has the charge port in the same spot.
francis_t_catte··on Homebound: The Long-Term Rise in Time Spent at Home Among U.S. Adults
it's almost like western society, particularly in the united states, has spent the last 70 years intentionally stripping away community and easy access to a third place.
francis_t_catte··on Interposer to fix the Symmetricom SyncServer S200 GPS week rollover problem
I have a Symmetricom ExacTime ET6000 that had a Motorola Oncore M12+ mounted to an ACE-III interposer made by Synergy systems that hadn't suffered from a rollover yet, but instead had a 3 month leap second induced offset. I went the (mildly easier) route with a Furuno GT-8736D, then modifying the interposer with a level shifter for the serial lines as the ET6000 uses 5v TTL logic, and the Furuno chipset is only rated for 3.6v maximum (and so was the M12+, for that matter!).
francis_t_catte··on Diagnosing video signal loss on Wii and GBS-Control
it's likely not the dimmer's fault; phase angle triac dimmers were designed when resistive loads (incandescent light bulbs) were king. except for the super-low-wattage-per-lumen type, most LED light bulbs I run across these days are based capacitive dropper power supplies, which are inductive by nature (hence their atrocious power factor). combining that kind of load with phase-angle dimming is a recipe for crazy harmonics many orders of magnitude higher than the 60Hz base frequency.
francis_t_catte··on ESPHome
Use something like an Aube RC840T-240; it generates an isolated 24vac supply and has an isolated normally-open 24vac input for closing the contactor. Using anything else is liable to cause life-threatening spiciness if something goes wrong.

I use one for my addition's electric baseboard heat, and control it with a standard dry contact thermostat, but you could easily use a mosfet or relay controlled by an ESP32 or similar instead.

francis_t_catte··on How to Replace Your CPAP in Only 666 Days
I had a similar experience with a common, cheap medication, where my insurance started denying the prescription out of the blue. it took several weeks of back and forth with my doctor, and then a lengthy amount of time on hold with the insurance, company where the exasperated pharmacist and I were eventually told that only 15, 24, and 90 day in person pickup supplies were now covered.

my prescription was for a 30 day supply.

wait until you learn about 'engineered beams'

I shudder thinking about all the structures built with those things that're one undetected bathtub drain leak away from serious structural failure.

francis_t_catte··on My SBC Collection
the Sheevaplug, Guruplug, and Dreamplug are what really got me into embedded computing and linux. I still have my Sheevaplug in storage, and a Dreamplug in service as my internal DNS server. the Marvell Kirkwood SoCs they were based on were quite long lived, eventually being rebranded as lower-end Armada chipsets.

P.S. if anyone wants to tinker with that ecosystem, there's still quite a number of people dedicated to packaging up Debian for them, and if you're okay with some soldering to get UART access, you can get a brand new $18 Dell Kace M300 to try out. in a lot of ways, I still prefer them to any newer single-board computers, despite my pretty significant collection at this point.

francis_t_catte··on Amtrak Explorer
That would, unfortunately, require actual infrastructure investment into trackage and electrification, and the nationalization of all the Class I freight companies. I'm not going to hold my breath.
francis_t_catte··on 12 years since Saab’s bankruptcy: Secret NEVS electric cars revealed
the Tipo Quattro platform deal with Fiat, Lancia, and Alfa Romeo had no GM involvement and it was finalized over five years before GM ever bought controlling interest in SAAB-Scania.
francis_t_catte··on Daft Punk Break Up
if you like Carpenter Brut, I recommend Perturbator, especially the album The Uncanny Valley.
francis_t_catte··on Build a Raspberry Pi CM4 4-Bay NAS with Wiretrustee Carrier Board
Hm, rack mounted fiberchannel drive enclosures exist (~$100 used on fleabay, usually sans disk trays), but that'd require a fiberchannel card in your server, direct attach copper (or fiber) cabling, and driver finagling.
francis_t_catte··on GitHub has received a DMCA from MPA about torrent tracker nyaa.si
yeah, this reads as more of an attempt against the torrent tracker site, rather than the tracker software itself.
francis_t_catte··on Odroid-Go Super: $80 Games Console That Looks Like a Switch, but Runs Ubuntu
I used a USB AC-wifi dongle on my Odroid-Go Advance, and the performance/latency was about the same as my genuine SteamLink on a gigabit wired connection. The main problem with the Odroid-Go Advance was the screen resolution and size making most UIs unreadable or a chore to use. The screen resolution increase on the Super might help with that though; I plan on getting one once they release, so I guess I'll find out.
francis_t_catte··on Odroid-Go Super: $80 Games Console That Looks Like a Switch, but Runs Ubuntu
Steamlink, however, does work on ARM. :)
francis_t_catte··on Why Is There a Bucatini Shortage in America?
Wegmans is a no-go where I live, thanks to an old 'handshake agreement' between the Wegman and Golub families, in that there would be no overlap between Wegmans and Price Chopper territory. :(

I'll have to check Hannaford and Shoprite instead.

francis_t_catte··on A chain cuts through a capsized cargo ship filled with cars
The key to the salvage effort not involving refloating is probably related to the loose tangled masses of vehicles it's carrying; the ones that already caused the ship to fall over.
francis_t_catte··on Guitar Center files for bankruptcy
Every Guitar Center I've visited in the last year or two had that 'going out of business' feel. Not surprised to find out Bain Capital was involved.

francis_t_catte··on The self-driving car is a red herring
So what if we eliminate some of the hard problems, like steering, traffic, pedestrians, and setup guided routes specifically for automated vehicles? All you would need to control is signaling and the throttle/brakes. You could even couple multiple vehicles together for more capacity! Seems like an idea ripe for implementation. /s

have you ever heard of... trains?
francis_t_catte··on GM sells out first year of electric Hummer production
The Fits sold in North America were assembled in Suzuka, Mie, Japan, up until 2014. Parent commenter is probably referring to the Tōhoku earthquake and subsequent tsunami in 2011.

francis_t_catte··on Building replacement proprietary battery packs
For a while I was scrapping dead laptop batteries to build an 18650 pack for my esk8 build. I ended up building a battery validation rig with a Turnigy battery charger that charges the battery to 4.2V, drains it to 3.8V, and charges it back up to 4.2V to figure out its true storage rating. Then I sorted them by manufacturer, model, and storage capacity, with a recycling bin for anything below 80% of their rated capacity, open cells, and shorted cells.

It's a lot of work, but the validation was all automated via the charger. The pack I ended up with had healthy cells all within 10% of each other in terms of capacity.

francis_t_catte··on Palantir Admits to Helping ICE Deport Immigrants
Considering borders are meant to control access to wealth and opportunity, you could argue the answer to all of your questions is very much "yes".
francis_t_catte··on Microsoft to acquire ZeniMax Media and Bethesda Softworks for $7.5B
Soon we'll just have Microsoft, Epic, and a conglomeration of EA, Activision, and Ubisoft after Bobby Kotick forces them all to merge. Facebook will bungle up any chance they have of capturing the gaming market after writing a cryptic paragraph about their legal right to request blood samples from all Oculous users in the TOS. Valve will quietly exit software development altogether, and pivot to building custom vanity knives using their hardware manufacturing experience. Can't wait for the future GAAS market!
francis_t_catte··on Backdoors and other vulnerabilities in HiSilicon based hardware video encoders
all the HiSilicon stuff I've RE'd had hardcoded root passwords less than 8 characters in length, and a telnet server running with root login permitted. many of the passwords I've run across are actually the SDK defaults. all but one used the default webadmin setup included with the SDK that allows downloading a config backup that includes the passwd file. not much need for a back door when the front door is wide open...
francis_t_catte··on 1930s Household Refrigerators (2013)
Anecdote, but I rescued a 1947 Kelvinator C-7-R (essentially a 1930's pre-war design) last year from the National Grid fridge scrapping scheme. It'd sat in an unheated garage since 1993, after being continually in use by the same family from 1948 to 1993. I plugged it in once I got home, and it cooled down to 38F within an hour. :)

Functionally, it just needs a new door seal to go back into service. Unfortunately I turned it into another restoration project... the original glass drawers got smashed in the 70's, and replaced with pieces of wood paneling, the interior door panel is cracked, and most importantly, it needs all the wiring replaced.

Something of note for post-war appliances like this; due to copper shortages, a lot of manufacturers switched to aluminum wire. This, combined with the natural rubber insulation, and the lack of grounding, it's basically waiting to electrocute me, then set my house on fire.

A lot of other 40's and 50's appliances are probably the same in terms of aluminum wiring. Pretty much everything prior to the 70's is gonna be full of natural rubber insulation and no grounding (or double insulation), however.
