I remember watching the (excellent!) Tesla Autonomy Day presentation, and an analyst was asking about 'chiplets' but was met with a bit of dismissal from the Tesla team. Maybe THIS is what the analyst had in mind! Pretty cool stu

Note that the lockup for the recent spate of IPOs hasn't expired yet. It's possible that there will be a small recovery/bounce in the coming winter and spring. We'll see.

I've found that those same young kids also don't tolerate long periods in the car very well. The periodic stops to charge work pretty well - you stop, plug in the car, then take them to grab a bite to eat and blow off some steam.

Pretty cool to see FORTRAN, Zip files, "/Zoom Program.html" in the URL, yet see discussion of return-to-launch site with Falcon 9 and modern rocketry. It's a nice reminder that you don't need React on a serverless d

It's a really interesting concept between an RTG and a full-on small fission plant. Basically, a tiny, simplified, nuclear fission generator. There's a link at the bottom of the page. Something I learned about today! https:&#x

Interesting stuff! I recommend starting the batteries out at full. Otherwise it seems you always have curtailment early on... Seems more realistic (charged batteries don't weigh any more than empty ones). Also, what about fuel cells

This isn't some 4,000 pound Tesla. According to https://mi-xiaomi.net/specs/ , the scooter uses 1.1 kWh per 100km. Let's say you ride this scooter 10 miles a day on your nice, short commute. That's roug

In my opinion, for DBaaS, number of cores, amount of RAM, and even I/O performance for the buck are secondary considerations. After all, for any non-hobby application, the data are significantly more valuable than the hosting costs. I

Sounds like you need a recruiting coordinator. They aren't all that expensive (compared to your time, or an engineer's time).

Service with Tesla has been pretty good. For small things (like problems with those notorious doors) they will drive to you and fix it, even if the car is in a parking lot at work. You can schedule over text message and in the app. It&#x

It's ironic that it's a Boeing with bad software (or sensors) interfering between yoke and plane. After all, historically, Boeing has had the philosophy of trusting the pilot with direct control of the plane. This is in comparison

Yes, definitely, even with high-electricity-cost utilities. Even the big, heavy older Teslas get the equivalent of at least 60 mpg (say, 300 watt hours per mile at 15 cents per kWh vs $3 for a gallon of gas).

I agree with you. Remember that this was a time of rapid improvement in computing hardware, and these were devices marketed to kids in family rooms. That hardware cost inefficiency is a big reason cartridges lost to discs. (and, later, dow

Game cartridges are pretty cool. Unlike a modern game download, the cartridges could extend the functionality of the base system, allowing console manufacturers to extend the life of their consoles. My favorite example is Star Fox for Supe

The article has a price sensitivity analysis for cobalt, which suggested that a doubling of cobalt prices would result in a meager 2.4% increase in battery prices. That cobalt price increase would open new mines, so I’m not too worried abou

High-end e-bikes are pretty awesome. The power output is surprising. They can do things you wouldn't expect, like go up a flight of stairs or go 25 mph or pop wheelies. Think of one like a light motorcycle with a high-torque 1HP motor

I agree! The latency improvement is the interesting one, but honestly LTE latency is already pretty good. I wish there were more efforts behind IOT support, by way of lower-frequency bandwidth and low-energy radios, maybe even restricted t
