As someone who loves Rust the language and tool set: This class of projects [LLM rewrite of a reliable piece of software honed over decades) is embarrassing.

If you are watching this and haven't used rust: Please don't judge the language by this part of its users.

Great point. Stated another way:

"Mom, can I have battle-tested, reliable software"

"We have battle-tested, reliable software at home"

Battle-tested, reliable software at home: (Pic of green text from `cargo test`)

I built this after lamenting the friction in repeating commonly-executed tasks in OS-native terminals. This supports native functionality, while making it easier to use.

It's a standalone executable. Has a GUI version as well, (EGUI) in rougher shape. E.g. this will continuously show you the various lists of recent commands, dirs etc, and has a file browser.

Highlights: Good autocomplete. Knowledge of what directories are commonly used. Dir Bookmarks. Syntax highlighting. Integrated SSH support. Convenience functionality for git and python venvs.

For anyone out of the loop: Size/key count is the new(ish?) metric which perhaps most accurately categorizes the keyboard hobby. E.g. if you look at reddit's r/MechanicalKeyboards, they're mostly <80% layout.

I'm curious about the details: What is the definition of Left Wing you observed? (Or collection of traits). It is a term which means something different to different people. I'm also curious what your native language and country is, due to your use of this in contrast.

edit: Because it's so prevalent in the global news, I will mention this. May or may not be relevant depending on the specifics of what you've noticed: The current US president is an existential threat to our Republic. The most corrupt one in history, and an authoritarian. It is difficult to reconcile being a patriot and maintain a coherent set of ethics while not shifting left until this is resolved. There is a large portion of people who while may not normally align as leftists/liberals, but perceive this threat, as it's not a subtle one.

I encourage you to do research on extrapolation as a general concept. Not a deep dive, but to explore its general utility and limitations as a tool. I also encourage you to explore what metrics you use when evaluating the utility and impacts of LLMs.

Still blocks all my queries; downgrades to 4.8.

Related to graphics programming in rust: One reason to get into graphics programming is if there aren't any engines that suit your purpose that are available for your programming language of choice.

If I wanted to program a 3D game, I would choose UE5. I'm not, however: I made my own engine (`graphics` crate) and own vector/quatrnion lib (`lin-alg` crate), used by no one other than myself, to view chemistry and molecular bio visuals, with convenience controls etc. And it's suitable as a general purpose engine for rendering simple, non realistic scenes. I'm surprised I had to do this, but didn't find any suitable existing solutions.

This still is flags every query I send it due to safeguards, then switches to 4.8/Opus.

Hey - I tried this just now, and was surprised; you're right; it was ~$12.

My general assumption for any food I'm getting eating out in the US (across a range of regions) is $20/person for fast food/casual, and $30 if it's a basic restaurant. The food will be listed at $7-12 etc, but the receipt will show twice that due to fees, add-ons etc.

IMO what matters is what you pay; the numbers they post on the menus and other media aren't useful.

I will stick up for spiralcoaster. This post is direct and could be interpreted as offensive. Sarcasm both in general, and especially over text is often not appreciated. (It partially depends on culture). Yet, I think this analogy is appropriate here, and I was thinking along the same lines.

Stiffness. Important for how the frame behaves under load and buffetting etc.

Phrased in a slightly different way, assuming the standard is Betaflight/Ardupilot/PX4. (This article uses BF): Inner PID rate loop; this compares IMU-measured rates vs that commanded by manual controls. This might run at 1-4kHz.

On top of this (Maybe at a few hundred hz), you can add outer controls to set attitude. This could be an autopilot, or having the controls command attitude instead of rate. Betaflight pilots usually don't both with this, and have the simple setup of control maps to rate.

I've programmed firmware using a weird hybrid where the controls command a change in the target attitude. So it flies like rate, but has the forced attitude stability of an attitude-based control system. Non-standard, but makes it so you don't need to worry as much about tuning the PID loop. In practice, you can do full aerobatic flight with this like you'd do with a rate-only setup. (Basically, there is a commanded attitude quaternion; controls nudge it; the PIDs update motor power to maintain this commanded quaternion.)

I agree with your first point.

The milled fiberglass the author used is a much better UAS frame material than anything from a filament 3d printer due to stiffness and related considerations.

Jetbrains (PyCharm, RustRover etc) is as solid of an experience as when I started programming 15 years ago. I would recommend you give it a try!

What sorts of things does your software company make or do?

If you were reasonably confident the stock was overvalued and/or would go down, why would you not short it, (Or similar)? "Talk is cheap" and "Putting money where mouth is" are both trite, but applicable here. In the short term, this can misfire, but as a consistent mindset long term, it would expose whether there is value in these assessments.

To help you understand my mindset here: Picture a simple game or bet. RNG/dice etc. 55% chance for a $10 payout; 45% chance to lose $10. You would keep on rolling that die, right? I believe this is is close enough of a comparison.

Stated another way: Someone else who has no confident predictions about the market and is in index funds or similar, would love to be able to make confident statements about a stock (SPCX or w/e), because it would be an effective edge. They wouldn't just post about it on the internet; they would take appropriate positions.
