Wow, not one mention of the env vars that have a far greater influence on how the models actually work under the hood - https://code.claude.com/docs/en/env-vars

Very important for bedrock deployments and other not-as-standard deployments

Key for how I've deployed it - disable adaptive thinking, max thinking tokens, disable telemetry, etc

GPT-5.5 is a solid leap with Codex or other harnesses. Opus 4.7 I still don't understand how people use... I tried it for a day or two, have tried it for a few hours every week or so since release, and still use 4.6 as daily driver (with xhi thinking).

probably same thing for boeing 787 jets - https://www.theregister.com/2020/04/02/boeing_787_power_cycl...

says 51 days, which would be an interesting number of (milli)seconds

apparently you can straight up duplicate/add/rearrange layers without changing any of the weights and get better results as well - https://dnhkng.github.io/posts/rys/

There have been a couple "studies" and comparing various frontier-tier AIs that have led to the conclusion that Chinese models are somewhere around 7-9 months behind US models. Other comment says that Opus will be at 5.2 by the time Qwen matches Opus 4.5. It's accurate, and there is some data to show by how much.

Using this with tmux and various VPN tech. Main issue is scrolling. Termius + tmux don't scroll very well. And I've been led to believe tmux is necessary to keep sessions open when I turn off my phone screen

Thanks! How I eventually found it was stripping stuff back layer by layer. And by that I mean I started with the raw camera feed and got to where things worked well in a different swift view. And then from there, peeled stuff back from the main process feature by feature. And then bam, aircraft were exactly where they should be (minus the compass inaccuracy). I even had stuff like drawing mountain peaks (I live near Denver) as "aircraft" to figure things out, determining different FOV at different zoom levels (a lot of AI keyed in where the boxes would move in one direction at low zooms, be completely correct at some middle zoom, and then in the opposite direction at high zoom).

And that peeling back was me looking at each function to see what it did (I am a dev, but not for SwiftUI). So yep, can't vibe code it all!

Built an app entirely with Claude/AI assistance – backend (Django + C#), iOS frontend, server deployment, CI/CD pipeline, the works. Hosted on a single VPS. Postgres on VPS, Redis on VPS, Django on VPS, etc. The VPS is a VM I have in a proxmox server I have sitting in a datacenter (Dell R630, 1x Xeon 2697v4, 128GB memory, 6x 960GB Intel D3-S4610 with Optane SLOG, etc). No AWS/GCP/Vercel, etc. Incremental cost to me = $0/month. I skipped using CloudFlare tunnels for this - hoping I don't regret that.

What it does: Point your phone at the sky, see real-time aircraft info overlaid on your camera. ADS-B data from community feeders, WebSocket streaming, kinematic prediction to smooth positions between updates. No ARKit – just AVFoundation camera + CoreLocation/CoreMotion + math. SwiftUI overlays positioned via GPS/heading projection.

The humbling part: Spent 2 months debugging "FOV calibration issues." Built an 800-line calibration UI, a Flask debug server, Jupyter notebooks for pipeline analysis, extensive logging infrastructure. Hung a literal picture on the wall with a black rectangle of specific size to "calibrate" the FOV reported by my phone. The AI helped me build all of it beautifully.

The actual bug? A UI scale factor on the overlay boxes. Not FOV math. Not coordinate projection. Just scaleEffect() making things the wrong size. Commit message when I found it: "scale may have been fucking me over for a long time for 'fov issues'". Guess where the scaleEffect() function was introduced? That's right - AI generated. I asked it at one point something along the lines of "ok when you draw the boxes around the aircraft, make them smaller when the aircraft is farther away".

I went through 2-3 major model releases that I tested on this "hey I've been fighting a FOV bug for a while - can you please take a look and let me know if any issues jump out". Gemini 3 Pro, Opus 4.5, none of them found the "bug".

Takeaways from vibe-coding a full product:

- AI is incredible at building things fast – entire features in minutes. The entire UI, website, logo, etc, all AI. Claude Opus 4.5 kind of sucks at UI. Gemini 3 cleaned all that up.

- AI will also confidently help you debug the wrong thing for weeks

- Still need to know when to step back and question your assumptions

- Deleted 2,700 lines of debug infrastructure once I found the real bug

- Low performance? Just tell AI to rewrite it in a more performance language (load tested the process with 1000 connections - with Python/Django, tons of drops and latency spikes to 5000ms. Switched to c# and now it'll do 1000 and keep latency under 300ms)

Release process: painless, except for the test RevenueCat SDK key causing instacrash. Didn't test release locally. Approved in 6 minutes 2nd submission.

Question: what are people using to get super accurate heading out of Apple devices? The heading estimated error never drops below 10°. It's about 50/50 on being spot on vs not that close for the projections.

a 16" natural gas pipeline moving 200 MMscf/d at pressures >1000 psi (relatively standard numbers, 16" can go up to ~600 MMscf/d) has a power transport capability of 2.5 GW (thermal). burn that in 60% efficient combined cycle turbines and you get 1 GW of electricity. that's a lot easier than building 1 GW of electric transmission lines.

Other countries are very much the same. Almost always located near giant hydroelectric generation facilities. Brazil + Russia are two big ones that come to mind. Probably China too.

DDR4 prices are up 2-6x in the last couple months depending on frequency. High end, high speed modules (e.g. 128GB 3200MHz LRDIMM) are super expensive.
