This is a very strong biography telling a story of a deep commitment to public service and national defense. She’s running against one of the most malicious, ignorant, and least capable Representatives to have served in the U.S. House. One to watch!

Sounds like an advertisement….

Google DeepMind just did 800 years of research in months.

What they discovered makes the computer, internet, and mobile phones look primitive.

It will transform how we work forever.

Here's what it means for the future of humanity:🧵

@thatwafflegame the cookie that saves my settings seems to expire and revert to defaults every so often and that switches my timezone away from local and I end up having a day where I don’t get to play if I switch it back. :(

Please fix? (Also, no Mastodon account?)

Wow

The combined net worth of America's twelve wealthiest people just passed $2 trillion.

12 people. $2 trillion.

The bottom half of America collectively holds $3.5 trillion.

Wealth inequality is eating this country alive.

🌧️Be prepared for winter weather. Whether it's slick roads, snowstorms or heavy rain, a little planning goes a long way for your safety. Remember to slow down and leave plenty of distance between you and the car in front of you. MORE: https://t.co/BPyaXXpzbW

Fun fact;
In the outskirts of Portland is a nice little shop in an anonymous industrial park. You walk in to a little foyer with a folding card table and 9 thick, vacuum sealed Mylar bags, each about 1' long and 4" in diameter. They are sitting on top of about 70 pages of paperwork. This is the entirely daily production of this facility.
Inside are a bunch of old Mori Seiki NLX lathes - the old ones, before Mitsui bank let Dr. Mori train wreck the company with the DMG merger. Aside from a little wear on the interior paint, the 7 lathes look like they just came out of the showroom. In fact, the whole place looks like a machine tool showroom - spotlessly clean, with a thick, perfectly level urethane floor that a product photographer could use as a mirror white background plane in an Apple ad.
There are a few big things in our lives that are literally held together with a couple of fasteners. One example; every Boeing and Airbus engine is held onto the wing by only 2 bolts, and this is the shop that makes them. Boeing and Airbus both require multiple suppliers for critical components, so this is not the only shop that makes these bolts, but the nearest competitor is in Seattle (close to Boeing, but far enough away that the Cascadia Subduction Zone quake won't take both out).
The shop bay next door is equally clean, but contains a vacuum furnace and the most through inspection lab I've ever seen. X-ray and magnetic particle inspection, CMM, optical comparators. In the corner is a cherry red custom painted Lista cabinet where raw blanks are stored. An identical Lista cabinet in Green is at the opposite side of the shop. Raw material comes in, gets inspected, heat treated, inspected again, and moves from the Red to Green cabinet, collecting about half the paperwork along the way.
The blanks take about 3 days to go from a cylinder of Sandvik or Thyssen-Krupp steel into a bolt. One machine, the oldest, is used to rough the blank into a pair of concentric cylinders, the second oldest machine roughs the hex head, before the bolt is stress relieved and allowed to rest for 36 hours. Another machine finishes the hex and applies chamfers, these are final surfaces.
The final step is the threads, where things get interesting. They are cut in 3 steps; roughed, semi-finished, and finished. The secret sauce here is that a new insert is always used as the semi-finisher, and the semi-finished state is very very carefully measured to compensate that exact insert. The final finishing pass is taken in one (surprisingly healthy) hit using the data from the semi-finishing pass to be on-dimension within about 2µm. The key insight they had is that you get a better surface finish off of a tool that has already taken a couple of cuts. The threads look like you wrapped a mirror around a spiral staircase; their process is so dialed-in that their work competes with thread-grinders for dimensional and surface quality. Even so, just before inspecting with old-school thread wires at the machine - the guy running the lathe spins it at about 500rpm and reaches in with a Bright Boy stick and touches them up, runs his fingers over them, and gives them the most important QC they'll receive. This guy has been on this machine for 15 years; nearly every aircraft passenger aircraft in the sky is held together by at least one bolt that has passed his touch inspection.
Of course, the engineers in Renton or Toulouse won't just accept that Mitch in Gresham touched this bolt so it is good... so whole reams of paperwork are geared by regularly calibrated Zeiss metrology gear that does a complete dimensional inspection, another magnetic particle inspection (3 in total), and an X-ray. Having said that, Mitch rejects more than Zeiss does (about 2-3%).
You want to pay more than $45 for each of these bolts.

@gak_pdx Great story!

@CaitlinPacific Thank you for "I’ll Tell You the Secret of Cancer." So well written. Moved me to both tears and laughter. Loved the ending :)

@flowpoke Whew! I don’t remember but my recollection is that there was a guy reverse engineering the format. He had code on git that wasn’t complete but had a lot sketched out.

I moved in to other projects because it wasn’t complete enough for me and I didn’t have time for that project.

macOS: Is there any way to access the https://t.co/QuhqPVEfJm’s local Music Library data without talking to the Music server API (requiring tokens and keys and whatnot)?

I don’t want to access the current user’s Apple Music account. Just local music library. TIA

hey @BWBooks I appreciate that you're a B Corp and donating books and supporting non-profits, but I *really* wish you'd not send me books in *plastic envelopes* 😿

Lots of quality paper padded envelopes exist; even Amazon is moving away from non-recyclable packaging.

It pains me to announce that I was fired from Apple today.

I was the engineer responsible for designing the charge port at the bottom of the Apple car

@Lowes someone needs to fix your servers.

@jdrhyne I have a chunk of $FUV I’ll sell you ;)

It was 20x as many shares before they reverse split to avoid delisting. Now they’re in delisting territory again…. I’m down -99% currently with little hope it’ll rebound. *OUCH*

Not the same but…

[Dad @GeekAndDad]

@jaimeejaimee @jaimeejaimee so sorry to hear of the friction! What a terrible time of year to have this happen. 😿

Hoping for the best for you all.
