If it leads to someone purchasing a solution that solves a need, how is that zero value?
olex · 9 days ago
If someone has a legitimate need, they will look for a solution in appropriate locations (directories, search, magazines, what have you) and do not need someone to scream their marketing blurbs into the void in hopes of being noticed.
olex commented on Ubiquiti launches UniFi OS Server for self-hosting   lazyadmin.nl/home-network... · Posted by u/speckx

I have nothing but good things to say about ubiquiti. I run their cameras door bell and network switches at my house and have had nearly 100% uptime for years. Their ui constantly improves and it’s very well integrated into home assistant.

Lotta haters out there but this is just advanced as I want to get in my home lab; and the racks are just so cool even with their gimmicky front touch panel, it’s just so sexy when all the displays in the rack sync up on their animations. Whoever designed these things really had an eye for design.

I've been researching options for a new ground-up home network setup in a new house, and so far UniFi stuff is on top of my list. FTTH company will install their stuff up to an NT in the basement, and from there it'd be my setup - a UCG Ultra gateway, couple of PoE switches across the main house and outbuilding, and 2-3 Wifi 7 APs sprinkled around.

From all I've been looking at, looks like it's the most straightforward setup. Fully centrally managed via the gateway, leaves me plenty of options for PoE-powered security cameras and other expansions in the future, can be upgraded on a component basis when desired, and integrates nicely in HomeAssistant. And with all that, not even really more expensive than what seems like much more fiddly alternatives like the TPLink Omada system and others.

Maybe Notion should provide this feature then. No more hallucination!

Seriously, I think there was a recent HN submission about this precisely.

Claude Code is doing rounds right now. I picked up a personal project from a year ago (iOS app, not really a mobile eng here), and decided to go the rewrite with some new features to practice some LLM-skills. Honestly, the speed of development is so much faster compared to last year with Claude Code. It definitely helps that I generally know what needs to be done, so I can specify technicalities. And having a good E2E set up works as well.

But yeah, if Gemini with more context comes with a similar product, it could compete and win the developers.

+1 for Claude Code. I'm in the exact same boat - several personal projects with something of a backlog in each, that would've taken me maybe a weekend each to get done manually. Sat down with Claude Code a few days ago and hammered all of it out in an afternoon, it's very impressive. Not perfect, and as you say, having a good idea of what we're doing and how helps a great deal vs. figuring everything out from scratch. And having good tests and/or a stable test environment and processes running.

What is your backup strategy? What would happen if your NAS breaks?
olex · 3 months ago
Multi-layered.

- Important stuff primarily lives in commercial cloud storage. All of that is also mirrored on the NAS.

- Everything from the NAS SSDs is dumped to the HDDs every 3 days. Both use MergeFS, so if any one drive dies (or both SSDs, or both HDDs), I can replace it and still have a copy of everything.

The entire NAS is also occasionally dumped to an external HDD that's stored at my parents' place. So basically, if the NAS breaks catastrophically, I am at risk of losing some recent stuff that hasn't been dumped there yet, but nothing of actual importance.

The biggest issue to me is one of security. You have to find a way to expose your NAS to access outside the home to make it truly as convenient as the big tech cloud services. Some vendors help do this for you (Synology with QuickConnect); otherwise you're probably thinking about always using something like Tailscale or setting up a reverse proxy on a VPS that you would have to secure, patch, and monitor.

Some home routers also offer built-in VPN using Wireguard. Works amazingly well with my Fritzbox, near zero setup on the router itself and very simple config on the end devices.

When I built my DIY NAS, the most important factor was: I wanted it _silent_. No constantly spinning drives or fans. It sits in a sideboard in my living room, and I've been using a M1 Mac for years now that is completely silent in normal daily operation, so I've become a bit sensitive to any "computer noises" and wanted my continuously running hardware to be as quiet as possible.

In practice this meant: a passively cooled Intel N100 SoC, a Corsair PSU that shuts down its fan under a certain power threshold (iirc 35W-ish), and SSD-only main storage. I did include a system fan (low-RPM 120mm Noctua) that is actively controlled based on various system temps (stays off 99% of the time), and two HDDs that sit in standby spindown and only spin up for snapshot backups once every three days deep at night.

Very happy with this system so far. It houses my data dump, backups for all my systems (replicated as snapshots to the HDDs), hosts HomeAssistant/Z2M, and hosts a local-only Gitea that keeps up-to-date clones of all my Github and Gitlab repos.

Anything I host that's available on the public Internet, I don't do from home - that's all on various VPS' or AWS. To access my local stuff remotely, I can always VPN in to my home network.

Have Tesla with badly corroded rear brake discs. Software does clearly not help here. It was very bad at the end of winter. Now it’s getting better in spring. I am curious how does it look in autumn. Trying to use mechanical brakes occasionally. I had same story with corroded rear brakes on BMW. The solution was mechanical handbrake.
olex · 3 months ago
Which one do you have? I had the same issues with my '19 M3P, all the brakes were badly corroded a year into the lease. Apparently the software to keep this under control came a bit later into the lifecycle, and is not very effective if the problem is already apparent. Anecdotally, what was _very_ effective at cleaning up the brakes was blasting it for a couple laps around the Nürburgring Nordschleife - the grooves / corrosion went away almost completely :D

Now I have a RWD Model 3 with an LFP pack (SR+/"base model"), and have to use the brakes much more than with the old car (that had an NMC pack and almost never limited regen). Over two years in, brakes seem good as new, hopefully they stay this way.

How does this generally work wrt brakes needing to be used occasionally to not rust shut? Even with an ICE car if you don't drive a lot, and drive in a fuel efficient way (e.g. coasting towards red lights) this can be an issue resulting in an expensive surprise when you need to replace disks long before they are worn out.
olex · 3 months ago
Some EVs (Teslas are ones I know of) have software that occasionally lightly applies the brakes to keep them clean.

Also, on EVs with LFP batteries the brakes do get used a bit more, because a full and/or cold pack usually can only take very limited power from regenerative braking. Depending on the implementation in the vehicle, brakes are either applied automatically to still allow for one-pedal-driving (aka. "brake blending", making the difference unnoticeable to the driver), or throttle-pedal regen is simply capped and the driver has to use the brake pedal when they notice that regen power is not sufficient.

Check in unreviewed slop straight into the codebase. Awesome.

> Once Copilot is done, it’ll tag you for review. You can ask Copilot to make changes by leaving comments in the pull request.

To me, this reads like it'll be a good junior and open up a PR with its changes, letting you (the issue author) review and merge. Of course, you can just hit "merge" without looking at the changes, but then it's kinda on you when unreviewed stuff ends up in main.
