Hey machinist friends. I'm routing out stuff from flat aluminum stock, so I'm slotting through it with an end mill. I don't care about the slot width, only the dimensional accuracy of one side. What width cutter should I use? Larger cutters are stronger, smaller cutters mean less material removal. What optimization strategy do you choose? (Cheapest endmill? Whatever endmill you have? are both reasonable answers.)

vac or an air jet would get the chips out of there, usually smaller is better, 1/4 inch would be my pick.

Bowie was definitely who I was thinking of, but I can see the others now that you mention it.

For the LambdaMOO people out there, Loree just posted elsewhere that Dagard passed away yesterday.  I don't know anything more than that.

Every time this guy starts running around outside the windows at work everyone's all "The black squirrel!" and my brain silently adds "of Inlé" and it seems so much spookier.

+Thomas Scoville​, do you spend much time reflecting on your demeanor as a condescending prick? I recommend it.

Liberated from private share: JB Saunders evicted, out of business.  We lost Gateway in 1999, Tiger Electronics in 2008, Fistell's (which had been open since the 1940's) in about 2010, and now JB Saunders.  There is one component-level electronics store in south Golden, with limited selection.  +Oleg Mazurov +Sebastian Kuzminsky +Scott Converse

Around 3:30 p.m. on Monday, an off-duty Boulder County sheriff's deputy was just finishing his post overseeing the eviction of JB Saunders Company from its 4,000-square-foot storefront on Sterling Circle in Boulder.

Lunchtime ride.  I gained 2kg in the last week or so because the weather hasn't been riding-conducive, which converted me from able-to-draft-the-lead-climbers-up-the-hill to struggling-to-stay-midpack.  But I didn't get dropped.  Right near the end of the 35k, the ride turned into a sprint.  I hit a slight pothole and heard a dink!dink!dink! sound, assumed I'd broken a spoke.  Worse: I tore the hub flange off.  I <3 my American Classic wheels: half the price of other similar-weight wheels and easy to find repair parts for.  But, apparently, a bit too lightly built.  (Though, at 30,000 miles, still pretty satisfactory.)

+John Bump I like high flange hubs. They add even more.

There's this website, https://habitica.com/static/front -- and their thing is you set up all the tasks you have to do at work and home and then get points and stuff for accomplishing them.  Totally cool for procrastinators like me.  I am, however, questioning their methodology, coz I get more points for doing the dishes than I do for stabbing myself with a sheep-brain-coated screwdriver and making a next-business-day appointment to get a tetanus shot.

Dudes.  I just stabbed myself in the thumb with a screwdriver I was using to pry a sheep brain out of its skull.  This is how horror movies start.  #IwishIwereJoking
