@thdxr One thing I like about the old/current interface is that it's easy to see your different sessions bundled by worktree. How does this work with tabs?

@mitchellh Have you seen zmx (https://t.co/4feR3YRWFO) ? I am hoping we can get this kind of functionality integrated with ghostty. I've been using zmx + ghostty for a while now and it is the only good solution I have so far for multiplex + rendering from my actual terminal.

@davis7 Do you find a difference between using it via Opencode as a harness vs Codex?

@systematicls insert alexander chapman joke here

@JDVance Cool, now do Ashley Babbit

@macrocephalopod @quant_arb my theory is that the sysls is on noncompete and is bored af

[k3v @MrPhenomenon]

@0xfdf @systematicls @quant_arb Depending on your use case, bounding features can be good..if you believe your extreme observations are mostly noise that you don't want to fit on.

@bennpeifert Finding Alphas by (Igor / Worldquant) + Quantitative Portfolio Management (Isichenko) + EQI (Gappy) are probably the only things worth reading for Stat Arb since everything else just talk about pairs trading / shit that no one in industry actually does

[k3v @MrPhenomenon]

@systematicls @elletwocache I know 2 colleagues that left to run Consumer Edge growth alphas as PMs at multi strats.

I don't think any of them are PMs anymore.

Too high price paid, but if I was the only person shouting about obvious long term problems of Danya becoming alarming, requiring urgent measures from people around, while "friends" only cared about hiding it and erase evidence, its rotten to the core

@DeepDishEnjoyer Is that Schonfeld next to XTX? Jfc

[k3v @MrPhenomenon]

@thdxr Does opencode work with responses API? I've been using OpenCode for a while but recently started just switching to Codex for more complex stuff. GPT5-high (both codex and normal) just seems to have better harnessing or better use of CoT in codex.

@GrogBogan @beaversteever Just to be super clear, you're saying that you, someone outside the industry, is more qualified to talk about comp distributions of people at my firm than I am?

And if you don't think HRT is an HFT firm then I think we just live in very different realities. Good day!

[k3v @MrPhenomenon]

@GrogBogan @beaversteever To add some nuance, it is true that maybe the most naive latency arb techniques from 10 years ago don't work anymore but to say "HFT firms don't make money anymore" is kinda nonsense if you've read any articles about HRT's performance recently (and no it's not just them)

[k3v @MrPhenomenon]

@GrogBogan @beaversteever "why would you know anything about dev hiring?" Believe it or not, I have interacted with a dev before. I might have even spoken to hiring managers and evaluated candidates!

I'm obviously not going to tell you where I work, but HFTs have been making a lot recently....

@DeepDishEnjoyer dude works at baly fs

[k3v @MrPhenomenon]

@VictorTaelin I assume it's because the other tools don't use the Responses API

[k3v @MrPhenomenon]

@NickNemo17 @lord_fed @CodeofTrading @marketmike @thetradingagent I'm pretty sure almost none of those funds are 2/20. I've worked at at least one of them and have the impression that a lot of them are pass through..

@therobotjames If youre pulling from a single .db file, repersist it as hive persisted parquets. Then use polars for anything like this (more complicated functions) and continue to use duckdb for your simpler easy to do in SQL stuff. Or just use polars for everything.
