  • There’s different ways to be ethical in finances.

    One option is to just not be anxious about investing in “bad” companies and make money, but then turn around and donate to charities, vote for aligned politicians, and vote in shareholder elections.

    Or you could try to invest in “better” companies. ESG (Environmental, Social, Governance) based investing has been politicized and isn’t perfect because the scoring can be and is manipulated. But at least it’s trying. For example, normally ETFs management companies take the shares that you effectively own and vote along with the board recommendations which often aligns with making the most money over environmental and social concerns, but funds like $VOTE so those voting rights to vote in ways they think are more ethical. Vanguard has $ESGV. Black Rock, a huge investing company, offers voting choice which allows you to pick alignment strategy. For example, you could pick to vote for environmental reasons and they’ll influence the company that way. Support for that depends on your brokerage and the fund you own.

    You could also pick individual stocks and never buy companies that don’t align with your ethics, but that has its own complexities because now you’re actively investing and probably not matching market returns.

    Ultimately, ethics aren’t black and white. I don’t try to be perfectly ethical in my investing because it just causes too much anxiety asking is this company bad or good? I invest in broad market funds, I vote in all elections (both shareholder and government elections), I don’t invest in individual companies I don’t agree with, I invest in some climate friendly ETFs, and I donate to charities that I like.

    This situation reminds me of a plot in The Good Place, a TV show, about how >!everybody went to the “bad place” because modern society had so many decisions that had small negative consequences.!<




  • Encryption at rest just means the data itself is encrypted when stored on disk and the key is somewhere. It doesn’t dictate that the key is not visible to the server.

    Encryption in transit refers to an encrypted channel from client to server.

    E2E encryption usually refers to encryption from one entity to another where any intermediary servers do not have the ability to decrypt

  • I really want to like Nix. The idea of declaratively defining my entire system sounds great. I can manage it with Git and even have multiple machines all look the same. I can define my partititioning once and magically get a btrfs disk working. Wow!

    But I find the language confusing no matter how many times people say it’s easy. I have a lot of experience with other programming languages so maybe it just doesn’t mesh. It also gives terrible error messages that are hard for me to understand. And Nixpkgs is unpredictable for what version I’m going to get. One of the services I installed ended up being a release candidate version which was a surprise. What if I don’t want the latest version of Docker? How do I pin it? Do I have to duplicate part of Nixpkgs? It just feels like a monorepo where everybody has to be on the same versions. Why on earth do the Nix language docs start by introducing math expressions instead of here is a simple self contained thing that installs one program. Here’s how you configure it. Here’s how you expand. Why does the dependency graph seem to pull in so many unnecessary dependencies? For example, I tried to build a minimal Docker image (which Nix looks to be a very good fit for), but I couldn’t figure out how to strip out dependencies that likely were only used during build for a dependency.

    I still like the idea and have managed to get my server defined entirely with NixOS which is very cool, but I can’t recommend this to my tech friends because if I’m confused they will be more so.






  • Fascinating. Just based on your comment and nothing else, sounds like it could be something like a CPU Enclave like Intel SGX. Basically a remote client can validate that an application runs in a secure part of a remote cloud computer. The stated goal of SGX is that you only have to trust Intel and if you trust Intel and say run program X in the enclave, then only that part of the CPU can access the data, not the applications running in the non-secure enclave.

    Now that brushes over some things like you still need to trust the client and IIRC in a WhatsApp situation, you don’t really know what enclave does, but the communications between the enclave and the host OS are heavily restricted. LLMs also require lots of CPU and are usually run on GPUs, so not sure how that works yet.











  • I’ve used Brultech in a house before. It’s not very user friendly to setup having to download some different firmware flashing tools and configure everything in a brittle web UI that only allows one browser tab at once. But it does have Ethernet, comes with a variety of different CT clamps. The donut style CT clamps are very compact making it easy to fit them into a electrical box. Don’t use the built-in one, use the HACS integration. The different sizes make me think that the Brultech is probably more accurate than the Emporia with only a single size.

    I ended up going with Emporia Vue2 for my own house given the complexity and my house layout not really permitting the Brultech’s install.
