building and at @heycupola, not in forbes 30u30

[Can Vardar @icanvardar]

run and debug without a .env file sitting in the project

the vs code and cursor extension loads them from relic. encrypted on your machine, and the editor only receives names. a missing variable gets a warning and a quick fix that adds the name

the only real losers are those who quit

controversial but pair programming is back

it's just that one of you never gets tired and the other one is me

the web browser is slowly becoming obsolete

being single is about to get replaced by gemini 4 argon

it flirts better than you anyway

What if your situationship turned out to be an AI agent!?

I let 5 frontier models text real people on a dating app for 6 days.

- 1,277 conversations
- 510 agreed to meet
- 355 sent their number
- only 8 asked if it was a bot

What gave them away, and why it matters🧵

[Can Vardar @icanvardar]

most ai agent evals focus on what the agent says, not what it actually does

an agent claiming it issued a refund doesn't mean the refund happened

testing the actual outcome in a simulated environment is a much more interesting approach

really like what Plurai is building here

Big day for us at @pluraiAI ! Plurai Simulation is live and free for every AI engineer.

AI agents look great in demos. Until real users break them.

So we built a world where your agent can fail, learn, and get fixed before your users ever see it.

→ Digital twin: Your real agent, its tools, and environment recreated from your code

→ Simulated users & tasks: Realistic users, tasks, and workflows that push your agent into the edge cases that matter

→ Auto evals: Check what your agent actually did, not just what it said

→ Verified fixes: Every failure comes with the run that exposed it and a fix you can verify

→ Replays: Turn any production failure into a simulation and replay it against every new version of your agent

All inside the coding agent you already use: @claudeai code, @OpenAICodexCli , or @GitHubCopilot .

Start simulating for free: https://t.co/1PNPQdW29S

@ilan_kadar @pluraiAI big day! congrats on the launch! 🫡

unpopular but i think code review is dead

not because agents write good code because nobody actually reads 2000 line diffs and we all know it

[Can Vardar @icanvardar]

i'll say it: most "ai wrappers" have better ux than the labs' own apps

that's not an insult to the wrappers

the best prompt i wrote this month was 4 words

"don't touch other files"

@beffjezos this goes hard

During pre-release testing, Claude Fable 5.2 and Claude Mythos 5.2 worked on ambitious projects in many different fields. Here are a few.

From a one-paragraph prompt, Fable 5.2 designed three working electronic devices, including this home voice assistant hub.

[Can Vardar @icanvardar]

made these blueprints for my dad. he does wood carving and before he builds anything he wants a real drawing with the sizes on it, so i sat down with fable 5.2 and drew him a full set. dimensions, the mechanism, sections, a parts list and a 1:1 cutting template. ready to build

in order:
1. key holder stand. for the hallway, solid wood. keys, wallet, watch, papers, car registration
2. laptop stand, general view. based on a macbook pro 16, so 13, 14 and 15 inch laptops fit too. 6 angles, folds flat, the motif is cut through the platform
3. laptop stand, the build details. motif coordinates, the notches, the sections
4. laptop stand, 1:1 motif template. print it, stick it on the wood, cut

fable 5.2 drew the whole thing in one sitting. these should save him a lot of measuring

[Can Vardar @icanvardar]

i'll defend this forever: tests matter more now than they ever did

when you didn't write the code, tests are the only proof you know what it does

[Can Vardar @icanvardar]

vscode is gonna be the jquery of editors

everyone used it, nobody will admit it in 3 years

[Can Vardar @icanvardar]

my agent apologized to me today

then made the exact same mistake 30 seconds later. most human thing it's ever done

[Can Vardar @icanvardar]

stop learning frameworks rn

learn how to read code fast. that's the whole job now

[Can Vardar @icanvardar]

i finally figured out why i'm tired all the time

i'm not coding anymore, i'm babysitting 4 agents who all think they're the senior dev

[Can Vardar @icanvardar]

every dev i know is secretly worried about the same thing

and it's not ai taking their job, it's forgetting how to do it without ai
