Unpopular opinion:

AI’s worst code doesn’t even come close to the absolute garbage I’ve had to clean up from humans.

Post your worst inherited code story below👇

@suryanox7 Even if I did experience that I guess my biggest push back would be that humans coding by hand also introduce new bugs. and regardless fixing a fee bugs makes up for the weeks and months of time AI saves you.

[Greg Ellis @cubesol_greg]

@suryanox7 Weird. I do not experience that in my workflow.

I agree that a single AI agent is probably capped around 20x productivity. I don't see anyone getting the equivalent of 8 years of development done in 1 month with a single agent today.

However, if you can run 5 agents in parallel on a project that's easy to split into independent work loads, then 100x increase in output is probably doable. The multiplier comes from both AI acceleration and parallel execution combined though.

👋 I'm Greg. In the early 2000s I built ClubDJ Pro — desktop DJ software with thousands of users. The iPhone/App Store wave wiped it out around 2010.

16 years later I'm rebuilding it from scratch, solo. Just shipped a sampler that pitch plays + slices vocals live.

Building in public just for fun🛠️

@ihearcanvas Check out @ihearcanvas's We Are Farmers / Jesus Walks Remix! It's awesome! 😍

Still deep in rebuilding the sampler for my DJ software, so I needed a real test: could I recreate @iHearCanvas's legendary "We Are Farmers / Jesus Walks" remix?

Mine's nowhere near as clean as his yet, it's pretty rough 😅 — but it's getting closer every build. Will be easier when i eventually get controller support added ;)

Progress demo 👇 Full credit to @iHearCanvas for the original (go watch it on t1k t0k, it's incredible link to his remix below).

Spent the last stretch teaching ClubDJ Pro to mix itself like a real DJ would:

→ finds the mix-out/mix-in spots by phrase, not just by beat
→ stem separates the bass so two tracks don't mud out on the swap
→ blends the video crossfader at the same time
→ ships on Mac/Windows + iOS

Here's a fully hands off transition 👇

@asaio87 Not for anything complex. For advanced digital signal processing, low level audio/video mixing tech it can't do it. In fact, Codex couldn't either. Only Opus 4.6+ has been able to handle this adequately in my experience thus far.

@RobKuhn_ happens all the time.

Confession: I have an App Store approved app I've been too scared to release. One month in "Pending Developer Release" now.

80 Summers - answer a health quiz, see how many summers you have left, get ways to earn them back. The screenshot does the talking.

It's done. It works. I just never hit publish, because I shipped the build before I had any idea how to market it.

Tell me I'm not the only one. And tell me if I should just send it.

@Gerry39464526 @HarleyMann68041 @kevinolearytv Ya, I hope there is a real option out there somewhere. It’s absolutely necessary

@WSOP @WAFoxen damn....

[Greg Ellis @cubesol_greg]

@PokerGO @phil_hellmuth It's only a matter of time before you capture that next WSOP bracelet Phil. Go get it man. Rooting for you 🙏

@pmitu Time to get comfortable doing the things we don't enjoy

[Greg Ellis @cubesol_greg]

code review is dead.

AI writes it, I merge it, prod confirms it.

raw dog everything 🫡

"do you review the AI's code" no. I trust him.

[Greg Ellis @cubesol_greg]

@suryanox7 no. I just let AI raw dog it

[Greg Ellis @cubesol_greg]

@mikeydsoftware good point sir… :)

[Greg Ellis @cubesol_greg]

@mikeydsoftware Nobody has enough GPUs 🤷
