Yes, added a link to the article you are likely referring to https://support.remarkable.com/s/article/Unable-to-update-re...

That was my initial reaction as well, when I first found the device not being able to update. But look what was the saving grace: SSH/USB/HTTP/Unix with root access, instead of closed systems, hardware that you own 100%.

As software is increasingly "solved" by AI I think this is what will become most important

There is indeed a "USB web interface" toggle under Storage. I've added a note in the final section, thanks.

Someone on Reddit also pointed out there is a support page for the clock issue https://support.remarkable.com/s/article/Unable-to-update-re...

Paper is great for notes, bad at rendering arXiv

I think you're right, the ending is a bit abrupt. Added a closing paragraph to the last section, thanks for pointing that out.

anything specific come to mind?

Using old EV batteries in grid frequency control?

oskrim — Sun, 21 May 2023 17:44:32 +0000

Has anyone thought about buying old EV batteries and connecting them to the grid for frequency regulation? Currently the FCR-N market in Finland is such that apparently you could make 30k€ a year with a 100kW setup. The average hourly price per MW has been ~36€/MW so far this year, so assuming you can participate without downtime the naive estimate would be

36€/MW * 24h * 365 * 0.1MW = ~31k€

This should be achievable on a 30k€ investment:

- 10k€ for the battery https://evshop.eu/en/batteries/292-2052-tesla-model-3-full-battery-pack-75kwh-long-range.html

- ~10k€ for inverter (Growatt WIT 100K-A)

- ~10k€ for grid connection + misc stuff

100% annual ROI. What am I missing?

See "Software Engineering at Google" https://abseil.io/resources/swe-book/html/ch11.html, the definition of a "small test".

This is roughly my definition of unit test: "tests run in a single process"

It is true. What your imaginary businessperson is saying is also true.

It's bullshit jobs all the way down.

Article is basically a rant against feminism.

What does this have to do with "gratifying one's intellectual curiosity"?

That's client side. If you load 3rd party content into your browser or fail to block, that's on you. I thought usage of ublock origin/privacy badger could be implicitly assumed among the HN crowd.
