I have had luck running Teams in the safari web app instead of the native (ahem Electron) app. Cuts the CPU usage down to 25% instead of 75%.

I expect we'll overbuild renewables to handle the high demand season and then dump excess renewables in the low demand season. I've seen this result in a couple cost optimization models like [0]. Optimistically, we might see deman

Thermal storage is harder to integrate with renewables because you need a recovery mechanism, i.e. a steam turbine. Because nuke plants already have the turbines, it’s cheaper to collocate the storage there. I could see a future where the n

21 Megawatts of power to run at full capacity. Wow! About the same power consumption as 16,000 homes. I’m not saying it’s a bad use of power, just that it’s impressive.

I’ve seen analysis that says we have enough lithium globally, especially if we use existing working recycling techniques widely. And there are other battery chemistries with earth abundant materials (e.g. iron redox) that could ease the lit

More transmission seems like a great option, especially since the lifetime of wires is measured in decades instead of years like storage. Another point in favor of transmission is the potential to apply high temperature superconductors, whi

I’m optimistic we could find a way to ramp nuclear up and down. We don’t do it now because it’s easier to run it at full capacity for economic and safety reasons. Adding some thermal storage (which the SMR companies are trying) or varying t

Great analysis, and I agree that renewable + storage is the right thing to compare against nuclear. I think the area where nuclear has the biggest potential to shine is competing with very long duration storage—e.g. month long underperforma

Gas also has staffing advantages over coal. A handful of people gan operate a bank of gas turbines; coal plants take dozens; nuke plants take hundreds.

It’ll be interesting to see what role hydrogen plays. Prices for using it to store energy are currently a couple times battery energy storage systems, and the component parts are not getting cheaper very fast (turbines + storage + electroly

I think yes, when combined with carbon capture and storage. The technology has worked for some time (both the capture and storage parts), some of the new direct air methods are hitting $100/MWh when paired with generation, bringing pri

Since it’s coming up a lot, here [0] is a good resource on levelized energy costs (i.e. per kWh). Energy costs are a tricky subject but in general new unsubsidized solar/wind is about the same cost or cheaper than operating existing nu

I’ve used fly.io for a couple new projects. The main thing I like about it is that it supports affordable and easy to use persistent volumes, something the container services (GCP, AWS) don’t. This lets me test locally with volumes in a way

I remote into a desktop wired into my home cable modem and basically use my macbook as a thin client a lot of the time. Modern remote desktop software is crazy good. Using parsec.app even from hotels it's almost like I'm sitting a

Running on a 2.4 Ghz Intel chip with 8 cores. The Excel code on windows got a lot more love than the mac code. Probably due to apple's OS and processor architecture changes over the last 20 years, whereas windows maintained great backw

Also the case for me with Excel on macOS. The Windows version of Excel, on the other hand, has been a lot more performant and stable for me.

I liked the way Apple did it in their Numbers clone of Excel - you can have multiple grids on a single page. It makes it a lot easier to have related data on the same page without fiddling with the row/column sizes to suite multiple ty

I was having dinner with a climate researcher in his 60s a while ago. What he did previously came up, and he said he was a nuclear nonproliferation researcher before, but climate change seemed like a bigger threat. Time has come to switch b

Maybe there isn’t a math replication crisis, but there is a kind of math fragmentation crisis. Sub-fields of mathematics have gotten so deep that specialists can’t communicate with one another [0]. I’ve heard this expressed by other mathema

As another commenter pointed out they are pretty adamant about not going open source [1]. But then later they walked it back a little and claimed they are "like open source" [2]. Funny there are 12 reasons for being closed source

I've been working around this "death of RSS" by making my own feeds via scraping (using fetchrss.com/manual). It's more fragile than using supported RSS feeds, but it gets the job done.

Yes. A mathematician explained it to me as an alternative to a fourier transform: instead of describing the function as a sum of sine waves, its a sum of mexican hats (or whatever basis function). And it turns out that’s a simpler represent

I agree adapting the natural gas infrastructure to hydrogen could have big benefits. There might also be a place for ammonia storage/transport here. It's a denser fuel, which gives it some transportation applications (creating a b
