@paolino Claude is writing better code for me again after previously it being Codex. Codex is great as a reviewer to catch things Claude misses. I’ve used / I am using both extensively btw.

I've been watching this since the first Codex dropped. There's no comparison. Codex is miles ahead of Claude Code. But the narrative won't stop. Which tells me people didn't actually try Codex before confidently declaring a winner. Even Opus 4.6 on max effort hallucinates constantly, confidently. Not on maxed out contexts, on fresh conversations. Today: hallucinated results it should have searched. Blindly changed one without verifying. Searched but got the wrong answer. Then doubled down on a mistake it already made. Just a mess. 20 minutes for a simple row of feature comparisons. Codex: searched everything, found nuance, suggested ways to represent it in the table. One shot.

@Shpigford Commit them to the repo.

does your team do anything around sharing /skills either on a project level or a company level? if so, how do you do the sharing (git repo, dropbox, etc etc)?

@rowlsmanthorpe What’s wrong with it?

If you want to know how corporate uptake of AI is going in the UK, M&S just sent out a press release boasting about their purchase of 11,000 licences for... Copilot

@rudekyoni999 I tried B1 + B3 can't say I am noticing much of a difference tbh.

High intake of B1,B2 and B3 puts you ahead of 90% of the human population

@nateberkopec Nice, didn't realise you had all those. Just bought the Performance Apocrypha

@xtianrobbo Buy anything from nateberk.gumroad.com and you get an invite. Part of the reason why the community works so well is you have to pay to join.

The power of my Rails Performance slack channel: I @-mention an engineer from a top Rails company about what they're doing, they respond instantly with a case study about how they reduced cumulative CI build-minutes by 33% by switching to fixtures (48 hours PER BUILD!).

@nateberkopec Is it closed off now or can anyone join?

I started giving away Slack invites to anyone who bought my book 10 years ago, as an afterthought. Turns out in the end it may have been even more valuable than the book itself.

@Shpigford Cron jobs.

i just opened my terminal and...it says i have mail?!?!?! WHAT DOES IT MEAN?!?! WHERE IS MY MAIL?!?!?! IS IT IN THE COMPUTER?!?!?!

@gfodor @mmeJen Looks suspect tbh, difficult to tell 100%.

@xtianrobbo @mmeJen real

I have zero idea if he is alive, injured or dead. But if they want to convince people he's alive, he needs to appear in public. BS videos like this convince no one.

@gfodor @mmeJen Coffee cup?

@mmeJen it's still possible to use your eyes to tell if a video is AI or not. things that 'detect' AI are just bullshit snake oil. to my trained eye, this video is real. I see zero evidence of AI in this. next year it won't be possible anymore, but today, it's possible to say.

@PositivFuturist Anyone who focuses on outcomes is having a much better time adopting AI.

This is the dude who won’t approve your hotfix because it doesn’t abide by unix principles.

@BethRigby @SkyNews A solution to a problem they helped create. Amazing logic.

NEW: Reform are subsidising prices at a petrol station in Buxton to promote their proposal to cut fuel duty in the wake of the Iran War - more on @skynews later

@aarondfrancis Worktrees are useful for low-value fixes, bugs, minor changes, etc. Or just letting AI take a first pass at something. As soon as the difficulty ramps up, I'm working soley on one thing. Why worktrees over git clone? Lower disk storage & I like you can't checkout the same branch

Why do people like git worktrees over discrete checkouts? (This isn't bait, it's research)

@pvncher @LuciferMornens Adjust in what way?

@LuciferMornens Yeah you have to adjust your prompting style a bit, and I iterated on the system prompt I feed it to compensate too.

Ok, I might’ve been wrong about gpt 5.4 It is good, once you learn how to steer it. Because compared to previous models, it seems like this one has a learning curve. You were right @pvncher . This is way better than gpt 5.3 codex.

@BilalBudhani Claude Opus or Codex 5.3 xhigh. Personally I think both are really good. If you invest some time with agents.md Codex is brilliant, slight favourite at the minute.

No matter what GPT model I try it doesn’t write Ruby/Rails code as well as Claude Opus or Sonnet for that matter. What model & coding agent are other Rubyists using?

@AndrewJ61756940 @gfodor This.

@gfodor This is a site already well known for seeding propaganda narratives.

@charlieholtz @jnunemaker Would be nice to have more flexibility with worktree base branches! Sometimes I want develop, sometimes I want main…

@jnunemaker got it thanks. so the main thing is you'd like to work off main? also how has perf been for you?

Conductor and Superset update. I find I'm using superset for quick and dirty stuff on main or a branch (less for worktrees). For example, it's super fast to just crank out flipper gem updates on 5 apps at once. For anything I do longer feature work on, conductor is nicer (when performance is ok).

@ujo4eva @peterrhague @rtheoryxyz CachyOS seems best for normies. I personally use Omarchy but you need to get comfortable navigating using your keyboard

@peterrhague @rtheoryxyz I run Omarchy and CachyOS currently. The latter, especially was very easy to get up and running with

Every Linux user has to ask themselves “which distribution should I choose” and oh boy that decision is about to get a LOT easier

@jimNjue_ Yep, X used to be so good for following live events like this. Feels like something changed...

Does anyone else find it odd that Israel was reportedly hit with 50 missiles last night, but there are very few videos of the attack circulating on X?

@JoePepitone_ @BerbarianWizard @JustinMihaly Great, will look into this. You tried this combo?

@xtianrobbo @BerbarianWizard @JustinMihaly Correct on B-complexes. Buy bulk powders from places like purebulk or bulksupplements. Purebulk now has a TTFD, too

I’m too bullish on vitamin b1 being a trend to hit the industry very soon Just makes too much sense - It helps solve issues that majority of people are having - Hard to get sufficient amounts from food supply - Fixes metabolism + gut health issues - Makes mental energy and focus go nuts (especially alongside armodafinil) - Fixes the “I feel worse after eating carbs” issue Very bullish

@JoePepitone_ @BerbarianWizard @JustinMihaly Will search it. More interested in overall health tbh. I was thinking a B-Complex may not have high enough doses of B1, B3 and B7.

@xtianrobbo @BerbarianWizard @JustinMihaly He did but that particular combo and dosing was for cancer. Search that particular thread.
