28 days agoOh nice! I’ll have to dig into that. Wonder if its an implementation issue across vendors. I was always under the impression that DHCPv6 was the common convention if not static.

Ok. So a device didn’t get a dhcp address? No problem… It creates it’s open IP address and starts talking and try to get out on internet on its own…
Its not that different from a conceptual point of view. Your router is still the gate keeper.
Home router to ISP will usually use DHCPv6 to get a prefix. Sizes vary by ISP but its usually like a /64. This is done with Prefix Delegation.
Client to Home Router will use either SLACC, DHCPv6, or both.
SLACC uses ICMPv6 where the client asks for the prefix (Router Solicitation) and the router advertises the prefix (Router Advertisement) and the client picks an address in it. There is some duplication protection for clients picking the same IP, but its nothing you have to configure. Conceptually its not that different from DHCP Request/Offer. The clients cannot just get to the internet on their own.
SLACC doesn’t support sending stuff like DNS servers. So DHCPv6 may still be used to get that information, but not an assigned IP.
Just DHCPv6 can also be used, but SLACC has the feature of being stateless. No leases or anything.
The only other nuance worth calling out is interfaces will pick a link local address so it can talk to the devices its directly connected to over layer 3 instead of just layer 2. This is no different than configuring 169.254.1.10/31 on one side and 169.254.1.11/31 on the other. These are not routed, its just for two connected devices to send packets to each other. This with Neighbor Discovery fills the role of ARP.
There is a whole bunch more to IPv6, but for a typical home network these analogies pretty much cover what you’d use.
9·3 months agoI use Nix, even on my Ubuntu machines, to install tooling in my user profile.
Nixpkgs unstable stays pretty up to date. The few I want something on release day or bleeding edge nightlies, I override the derivation source. I use nvfetcher to pull the latest release or head of the default branch as part of my update routine.
I’m pretty new to Nix, so its been slow integrating into my workflow, but I plan to start integrating flake’s into my repos. My team seems to have constant issues with keeping their tooling up to date which breaks things locally from time to time.
2·3 months agoI’m coming from a Haskell/Scala background. This job just pays more. TS has been “good enough” for types. I don’t think I could be as effective without them at this point.
I don’t see it dying from my perspective. Its only been getting better and better. The only thing I could see displacing it in my org is maybe Rust due to WASM proving a transition path.
We use TS on the back end to leverage our teams existing skill set and libraries we’ve built up.
I know it’s a meme to use “the next best thing” in the ecosystem, but we’ve been really happy with the newish Effect library + Bun runtime. Effect is like a merger of the older fp-ts/io-ts libraries (same author works on both) with Zio from the Scala ecosystem. It vastly simplifies the former and the new stuff with dependency injection and defect management is refreshing. With the Bun runtime, we see a 15x faster startup time (great for dev). Its halved the RAM requirements in prod. We don’t even need to transpile… We still do for prod to tree-shake dev-only code to ensure its not available in prod, but deploying to dev is FAST.
Anecdotal, but I only see OpenWRT out of the two in commercial products which hints to me its better supported (e.g., security patches and feature support).
2·3 months agoThere is support for this in Effect as another implementation.
4·4 months agoDisk encryption, computer login, and password manager are pass phrase + random characters stored on a pin protected OnlyKey and/or Mooltipass.
Regular passwords are just random characters up to
min(max_len, 128).
5x work shirts, 5x work pants, bagged/black t-shirts and fisherman pants for home, all black socks. L1 cache is the drier. L2 is the shelf next to the drier. There is nothing beyond L2.
If you are interested in pushing more, there are other JVM languages.
Scala was my first functional programming language after doing Java -> Groovy -> Scala. All 3 can access the entire Java ecosystem and are compatible with each other. Scala is like having Generics for your Generics (Higher Kinded Types).
Motivation is one hell of a teacher.
1·4 months agoPlus DNS caching… I do DOT or DOH (forget which, setup years ago) from my router’s local DNS server without any noticeable latency.
Might be a plugin. I think I’m using friendly-snippets (whatever is in LazyVim). There is also LuaSnip. They feed into my auto completion plugin as one of several sources.
Agree. What I linked provides core type support for that library. The pipe one is just a bunch of overloads to support a specific way of handling function composition to appease the TypeScript type checker.
There are a lot of typing hacks in that library to simulate higher kinded types.
Not OP, and these examples are not unreadable, but they are a few steps up from your typical generics.

They may not have to. For example, Plex on nixos just unpacks the deb and installs the files the “nix” way.
I don’t mind most of the language having FP experience, but I agree the lack of static typing just sucks. I’m using the repl a lot to try and track down why things aren’t aligning quite right when trying different techniques to keep things DRY and organized. Documentation is also a headache as a newb with the multiple ways of structuring a repo while trying to grok all the implicits and how it all gets merged.
Still figuring out Nix for my daily driver (too many fun customizations moving away from gnome), but love it so far and built my last self-hosted box with it. So easy to redeploy after the initial learning curve. Boot from ISO, partition with disko, upload SSH key to decrypt sops, install.
Oh and since practically everything can be overridden, its easy to get bleeding edge using existing packages!
3·6 months agoIts also E2EE making it private. Its what I use.
I use rclone and the Round Sync Android client.
Supports a ton of back ends, self hosted, and commercial options. You can transparently encrypt with private keys you control.
I personally use B2 Backblaze for storage.
My phone backs up every night and Round Sync pushes them to B2. On my desktop I can mount as a volume. I can also access my storage from my phone going the other direction.
I’ve done the same using SFTP if I don’t want the overhead of persistent file storage.
It does not support indexing or previews for searching or finding say a photo. You can put whatever you want for data. So I have caches, indexes, and thumbnails that work in Linux. I can’t really make use of those on my phone though.
Rclones bisync feature is also a bit dangerous when I tried to use it a year ago. I more than once “deleted” everything. B2 doesn’t delete by default, just hides, so I was able to recover. I now do unidirectional syncs from my machines to different buckets until I’m motivated to investigate a proper 3-way merge solution.
