The description of an unexpected/(impossible) orientation for an on road obstacle works as an excuse, right up to the point where you realize that the software should, explicitly, not run into anything at all. That’s got to be, like, the first law of (robotic) vehicle piloting.

It was just lucky that it happened twice as, otherwise, Alphabet likely would have shrugged it off as some unimportant, random event.

Prime used to mean something. Guaranteed 2 day shipping with no minimum for no extra charge. $5 for next day shipping. Then next day disappeared. Then the 2 day guarantee disappeared. Then delivery times were in the 3-5 day range for most things. Then, in my university town, around the time of students returning to school for terms it would be 1-2 weeks. I’m not paying an ever increasing annual fee for that.

I'm reconfiguring my printing closet (~6'x6') for a new printer and thought about enclosing the printer in a moderate sized cabinet (~2'x3'x6' - one "shelf" of the closet) for thermal control. Since there will be inevitable opening and closing, as well as just normal infiltration of the ambient air (usu ~65F between 40-75% RH) it would seem like a good application for a Peltier dehumidifier to keep the RH in the chamber low and reduce my need to re-dry filament which has been on the machine during (inevitable) multi-day or -week downtime between projects.

I've been wanting to try and make a mount for space gaming to go with my office chair - a Steelcase Leap. The organic-ish arms didn't make an easy way to create a clamp system, but in fooling around with it recently I noticed I could remove the armrest pads and they had a nice 4-bolt pattern. Since this is my office chair I need to be able to swap in or out of gaming setup easily.

I added a 30mm tall adapter that lets me slide a 6mm x 30mm (actually, 1/4x1-1/4) bar in and secure at the back, with a plate adapter to mount my old HOTAS4 to the bar, and a pin at at the rear for quick release.

The plates and adapters are eSun PLA+ which is fairly stiff but has some durability/ductility to it. The bar was supposed to be 6061-T6 aluminum but I was lazy and didn't feel like making a mess in the shop, ripping down some surplus plate I have, and I was too cheap to go out and buy 1/4x1-1/4 steel bar stock so I decided to print the bars from PAHT-CF (high temp nylon with carbon fiber). The 385mm bars just barely fit diagonally on my CR-10s.

In traffic, the largest reduction of efficiency comes from accelerating and the braking. You use energy to start moving (proportional to m V^2) and then you dump that energy into heat in your brakes to stop. The second comes from idling where you use energy to keep the engine rotating. As others have mentioned, EVs use regenerative braking so a substantial portion of the energy used to slow and stop the car is used to recharge the battery. EVs have no need to keep an engine running so unless you’re running the a/c there are minimal demands on a stopped/idling EV.

On the highway, you have the internal friction in the drivetrain to overcome, the constant deformation of the tires, and - most importantly - wind resistance, which is proportional to cd x rho x V2.

Cd (drag) and rho (air density) are low, but that V (speed) squared means driving at 75mph incurs 25x the energy use as driving at 15 mph. An EV gets no sage harbor here - plowing through a fluid (air) is essentially the same work.

To give you a sense of numbers, my vehicle (F150) gets less than 10mpg the 5 miles to my local pool/gym. The speed limit is 25 mph but there are stop signs every block or two. Lots of braking loss. On back roads with gentle curves and a 45 mph limit I get close to 30 mpg. That’s the sweet spot between overcoming transmission friction and air resistance. On the highway at 60 mph I get 22-23 mpg. At 78-79 mph I get 19 mpg. These are all generally on flat stretches using the 6 min average on my dashboard.

(Sorry for the long post…I’m an engineer and mechanical efficiency and aerodynamics are my happy place)

Which is why the Moderna vaccine will be priced at just 95% of the cost of the repeat treatments and hospitalization plus the value of the time saved and pain and suffering avoidance by the patient. Say, an extra half a million. I mean, what price would you put on avoiding seeing your parent or child subjected to round after round of chemotherapy?

The only way you die on that hill is from crushing as we are all crowded on there with you.

Hell, I picked up the book last year and had forgotten that Marley was a single (former) partner, not two brothers.

Banana for scale but, also, the desk is 6' long and the little monitor is 43" (and will be re-purposed elsewhere).

No, no - they're not raising the price; they're rebalancing it to reflect the value it delivers!!1!

And since they've reduced the free version functionality significantly, I believe I'm due a substantial rebate.

Oh, AutoDesk...you have such a way with words. Honestly, I would rather learn to design in OpenSCAD than send AutoDesk a single penny.

I may have the opportunity to upgrade my home office from dual 42" 4K panels to a single 8K panel. Actually, the two 42" won’t fit as my new space is limited to a 72" maximum total width so it's drop to one monitor or go big. I’ll be moving my gaming rig into the office so gaming performance will matter but probably only a couple hours a week vs 50 hours of CAD and office apps.

Although the easy answer is to grab the Samsung QN900C, it’s realistically more than I want to pay. I’m curious if anyone can say that there’s any day-to-day difference between the 900C flagship and either the 800C (or last year’s 800B) while I’m out looking for deals this week. I’m currently disregarding the 57" dual 4k gaming monitor due to the curve (it would obscure half my desk).

One reviewer mentioned disappointment that it's still a full 11.7" long and 2" thick. I realize that some people are not built for that kind of size, but I enjoy the heft and find the ergonomics of the original pleasing. I find that it stands out among smaller equipment and any substantial reduction would limit the versatility and, quite frankly, my overall enjoyment.

Good Lord - $2600 for a whole house system? I think that's what my local (mid-Atlantic US) HVAC shop is getting for a single-room mini-split.

Wait until people find out about ground-source heat pumps and water heater heat pumps. What you get out of those is more consistent year round, too. It's almost like leveraging technology has benefits over just burning carbon and hydrogen to make heat.

I looked all over the Golden Circle for some kitschy souvenir shirt to bring home and was hoping for a call back to the 2008 Journey movie with Brendan Fraser. Doubly disappointed as Aníta Briem (Hannah Ásgeirsson) is a native Icelander.

Since I couldn't find one, I made my own.

(I didn't actually make it to the Snaefellsjokull glacier in either of my two visits to the island. Maybe next time, and I wear my new T-shirt.)

Roll over and check to see what time it is on my phone. If it's within 20 minutes of when I get up, I'll probably go ahead and shower and make breakfast. If it's more than an hour before my alarm I'd definitely try to go back to sleep.

I thought they already announced they would be targeting their infotainment as a subscription based service.

I mean, the title is mostly it. I haven’t played DnD for…long enough that I know none of the rules and few of the classes. I didn’t play BG or BG2.

It looks so shiny, but I’m afraid I would just be 100% lost. Can anyone say what it’s like to go in cold?

Except for you Adobe. That's a cost issue.
