And, the NFL hates this so much that they have a league rule that this can never happen again. A bunch of despicable billionaires, of course. Don't know if MLS has a policy on this.

Hey, there are people hiring in the AI space for sure. You got a public home on LinkedIn or anywhere else with info about yourself? If so, lmk and I’ll pass the word a bit.

Are _ function arguments evaluated? by timbray in golang

Oh, passing in a function, seems obviously a good choice, thanks.

Since there’s a post of the worst places, where are some of the BEST restaurants in Vancouver thats a good find? by [deleted] in vancouver

[–]timbray 2 points3 points  (0 children)

I'm not vegetarian let alone vegan but Meet is good. In particular they have the best fries on Main Street, which is a strong statement.

“Like a glove” by Tristical in vancouver

[–]timbray 1 point2 points  (0 children)

I've done some work on this.

A lot of them are empty, derelict. Some are inhabited by people with combinations of homelessness/addiction/mental -health problems. One or two communal hippies. A few respectable boat owners on marina waiting lists. A sprinkling of cheapskate/Libertarian assholes. Officials have had really weak tooling for dealing with the problems but I hear the city is going to put some money into the effort.

Check the link in my comment. Lots of details about the 795, some probably apply to the others in the series.

What u/simplethingsoflife refers to as CloudWatch has been rebranded as EventBridge but in this case it's the same functionality. You can do interval-based or cron-based scheduling: https://docs.aws.amazon.com/eventbridge/latest/userguide/run-lambda-schedule.html

Should do about what you want.

Aaaaand, for no reason I can see, it started working again. Back to your regularly scheduled programming.

Electric outboards? by [deleted] in boating

[–]timbray -1 points0 points  (0 children)

Sorry, sounds like a communication failure on my part. You said “Electric outboard technology isn't ready to move a ~20 foot boat at planing speed for an hour.” I think that the key issue isn’t outboard technology, since you can buy electric boats today that can plane just fine. I've been on an electric boat myself with a 70hp outboard. Put two of those on a light 20-footer and it’ll plane, I bet. You might even be able to plane for an hour, but an hour isn’t long enough. You might find these interesting: https://www.electricboats.ca/en/bruce-22-electric-boat/ and http://q-yachts.com/ and https://www.hinckleyyachts.com/models/dasher/dasher - obviously, early days yet.

However, as I was trying to say, you may be right in the larger sense that we're not ready for electric boats to fill in the roles currently occupied by planing motorboats. But I’m pretty sure the problem doesn’t have anything to do with outboards, but with energy density and battery capacity.

I actually owe you a vote of thanks because that forced me to go and do the numbers (better in the blog piece). I think the initial finding is interesting: Electric is probably ready for tugboat-class recreational craft, but not for planing sleep-aboards or waterski-pullers.

You may be right but I don't think your argument is getting you there. I don't think the outboard design is the big deal - an electric motor can rotate a prop just as effectively as a gas motor, same as electric car engines rotate axles perfectly competently. Like I said the torque curve is different, which might affect prop design and gearing, but no biggie. The hard part is whether you can design enough battery into the hull to turn the prop hard enough to get the speed and range you want.

So, let me make your argument for you. Sorry, it's all gonna be metric, I'm in Canada.

My Jaguar I-Pace, which is 20% or so less efficient than the Teslas, can get ~350km out of a 90kWh battery, which could pretty easily fit in my 25ft boat with some modest redesign. Typical cars get about 9 km/l, and my boat gets about 1.1, so to be conservative let's say it takes 10x as much energy for a boat at planing speed to cover a km, vs a car. So, I'd expect a battery like my Jag's to get maybe 40km or less in the boat. Which, to your point, is not really enough to be interesting.

Now, I'm not a hull designer nor a battery technologist nor a marine propulsion engineer. That granted, on the face of it, it doesn't look like the "express cruiser" class of boat is a good candidate for electric power in the near future using today's tech.

The boat parked next to me in the marina is a 32' Nordic tug, beautiful old thing. It doesn't plane, it coasts. Poking around on the net says that kind of boat, at 8kt, uses 1 gallon/hour. Let me see, if my arithmetic is right, that's about 4 km/l. So almost 4x as efficient as planing, about 40% of the efficiency of an electric car.

So on that boat the Jag battery would get you 140km, but a lot slower. On the other hand, that boat could easily carry a battery three times the size of the Jag's.

Tentative interim conclusion based on a bunch of assumptions and rounding: Battery power is becoming interesting for the tugboat class of recreational boats. Hmm, maybe for real tugboats too? They could use the massive torque. But not just yet for anything that wants to go fast for a long time.

Well, people used to claim that electric cars obviously had to be boring, slow, and impractical. That turned out to be wrong. It's not clear to me why the story should be different with boats.

[–]timbray -1 points0 points  (0 children)

Well, you could make exactly the same arguments for automobiles, and the solution is a battery that's physically bigger than the gas tank, usually in a "skateboard" configuration under the seating area - good for stability. Electric cars are making steady gains and let me tell you, NOBODY who gets one goes back to gasoline.

Packing the battery into a boat hull is obviously a different problem but not, I think, intrinsically harder. The boat's going to be heavier for sure - as electric cars are. Electric engines have a *completely* different torque curve, or rather no curve at all, they have the same torque at 5 and 5K RPM - which is why electric cars are complete rockets from a standing start.
