  • +1 for GrapheneOS. Every time it comes up here people suggest buying a Chinese phone or running a Linux phone OS but never say what's actually more secure about those options. A Chinese phone just swaps Google's data collection for the manufacturer's own closed source stack. PostmarketOS can't make phone calls on most of its supported devices. The "firmware tracking" concern about Pixels applies to every phone with a cellular modem, and GrapheneOS does more to isolate that closed firmware than stock Android or any other ROM does. And it's a real daily driver now, sandboxed Google Play gets you RCS (group chats), most banking apps, even Android Auto.

    I do wonder how long Google will keep making it easy to run alternative OSes on Pixels, but the Motorola partnership is a good sign there.


  • We're able to quickly and safely ship the latest Linux kernel LTS point releases on devices with GKI (Generic Kernel Image) support including the 6th and 7th generation Pixel phones. At the time of writing on 2023-11-06, GrapheneOS is using the latest Linux 5.10 GKI LTS release (5.10.199) for 6th and 7th generation Pixel phones. The stock Pixel OS is on Linux 5.10.157 from 2022-12-02 with a small number of additional patches backported. This means GrapheneOS provides hundreds of relevant kernel patches including many security patches not yet included in the stock OS. It's possible for us to stay several months ahead due to their approach of moving to new LTS releases only in quarterly releases after a long freeze and testing process.

    From: https://grapheneos.org/features#more-complete-patching

    Edit: GrapheneOS ships kernel 6.12.73 (two minor versions behind but it's an LTS branch that gets constant backported security fixes) as of this month and gets LTS point releases out faster than stock Pixel OS. They're also the only Android OS shipping full security preview patches, months before public disclosure. "Not the latest mainline kernel" and "less secure" are different things.


  • China has more solar capacity than the rest of the world combined. Someone posted a photo essay of it a few days ago: https://e360.yale.edu/digest/china-renewable-photo-essay

    I've watched lithium battery prices drop 90% in a decade. That's Chinese manufacturing.

    The US just bombed Caracas and kidnapped Maduro. Trump said the US will “run” Venezuela and maintain “a presence in Venezuela as it pertains to oil”. One country builds solar panels. The other invades countries for oil.

    China is showing what it looks like to build your way out of the climate crisis. I respect that. The US is showing what it looks like to keep killing for the old economy.


  • Might want to look up "leverage decay" before holding SPXL long-term. Since it rebalances daily, after a drop your gains compound on a smaller base, so a 30% loss followed by a 30% gain doesn't get you back to even, it leaves you down 9%. That effect gets amplified in choppy markets.


  • Banks get overnight Fed liquidity at 3.75% using their assets as collateral. Regular people facing cash crunches get payday lenders at 400% APR or have to sell their stuff at a loss. That's an unfair deal, and banks are smart to take advantage of it. But it’s not really a good indicator of collapse. The 2019 repo spike looked scary at the time, rates shot up, the Fed stepped in, and nothing collapsed. This could be something similar. Could be wrong though.








  • It’s 400w worth of panels for ~$200. These are newer bifacial panels, so in theory you can get even more than that with the light that hits the back of the panel. Getting around 400w is still like best case scenario on the brighter summer day though. Shade and time of year matter a lot. If you’ve got just one panel covered with just a single leaf - it’ll probably take that panel’s output down to <%20. You won’t see much output during winter or cloudy/rainy days either.


  • Would have to plug things into the inverter. There are microinverters that basically allow you to plug panels into your house though (by syncing with the frequency of the power you’re getting from the grid). They’re much more expensive than this, and I think you’re not supposed to use those in the US unless you go through some sort of approval process. It’s becoming more popular in Germany for people to use microinverters for solar panels on stuff like apartment balconies.


  • You may also want a fuse (in a fuse holder) between the inverter and your battery for added protection against a short circuit (some batteries don’t protect themselves against this). The fuse holder I have is “Blue Sea Systems 5005 ANL Fuse Block“ but there’s a bunch of cheaper ones that look similar.

    It’s also a good idea to get a DC circuit breaker between the panels and the charge controller to easily be able to disconnect the solar panels to work on the rest of the system (or if there’s a problem). I got one of these: “DC Miniature Circuit Breaker, 2 Pole 1000V 25 Amp Isolator for Solar PV System” and it has the brand “Chtaxi” on it
