Definitely done with Twitter now. Going to keep the account to avoid someone else nabbing it but will be solely on https://t.co/TGU9XOI1nT now.

@[email protected] if you'd like to chat :)

You know you're officially cool when this is how you start your day.

[Jack Franklin @Jack_Franklin]

@jamescun easily bored and like too many fonts :D

[Jack Franklin @Jack_Franklin]

Hacked together a script that randomly decides my terminal font for the day, so I can mix it up (what a life!). Therefore, I'd like your recommendations for your favourite programming fonts please :)

@FootballManager skip FM25, do a small data update for 5GBP on Steam, focus on FM26.

[Jack Franklin @Jack_Franklin]

as a result, I was able to track down the problem and get a fix up within 30 minutes, which means it should be fixed in Canary soon and hopefully in M131 stable.

Shout out to @csswizardry for an excellent bug report for Chrome DevTools including a narrated video showing and describing the problem: https://t.co/wnIRDGOzqD

I understand not everyone can do this, but if you can it makes reproducing and fixing so much easier for us.

@ElliottZ glad it's not just me

[Jack Franklin @Jack_Franklin]

@HenriHelvetica DMs open, or jackfr at google dot com :)

@WebTwitr @ReactAdvanced how long are you in London? Fancy a coffee at Google?

[performance.now() conference @PerfNowConf]

We just added some more speakers to our #PerfNow line-up for November 14 and 15. @ericwbailey, Paul Williams, @tameverts, @ksylor, @Jason_williams and @Jack_Franklin will be with us as well! https://t.co/hLpd6jBEJ4

Had to setup some API keys internally for a thing and yup...it's so painful getting lost in GCP.

[Brendan Dolan-Gavitt @moyix]

OpenAI: pip install openai and set OPENAI_API_KEY
Anthropic: yea same but s/openai/anthropic/g
Google: oh boy. ok so you have a GCP account? no? ok go set that up. and a payment method. now make a "project". SURVEY POPUP! k now gcloud auth. wait you have the gcloud CLI right–

@lawrjones Yay! I remember doing this a few years ago and it was a huge moment 🎉💪

[Jack Franklin @Jack_Franklin]

@kyleshevlin In my experience so far I've found AI useful to help speed up the mechanical parts of software engineering, and I get to exercise more of my brain on the architecture and design and complexity, which I like. But sometimes I lose a bunch of time to AI giving me broken shit 😂

[Jack Franklin @Jack_Franklin]

@edspencer I think this is not me...I have not blogged about React in a long while and certainly not about RSCs...not sure where this URL came from!

[Jack Franklin @Jack_Franklin]

@rick_viscomi @csswizardry I'd really like to promote this from experiment to setting

[Jake Archibald @jaffathecake]

This is a fun one. "☰" seems to send the browser looking through a bunch of fonts to find one with the character.

When profiling with 6x CPU slowdown, the delay is significant (40ms on a high-end machine), but I don't know how realistic that delay is.

@WebTwitr long time Neovim user here who is always happy to chat :)

[Jack Franklin @Jack_Franklin]

One great use case has been asking AI for particular CLI tool invocations and command line flags to get to what I want (looking at you, jq). Again the AI isn't perfect but it gets me mostly there. I think smaller contained generation is the sweet spot for productivity.

[Jack Franklin @Jack_Franklin]

Finally dug into using AI in my daily workflow and my initial reactions are... mixed.

Biggest success is @SupermavenAI which provides inline editor suggestions. For mechanical, repetitive changes it's a huge speed boost.

[Jack Franklin @Jack_Franklin]

I recognise this will depend on use case etc and will undoubtedly improve in time...my main concern with AI in programming continues to be the impact on junior developers who will treat the AI as 100% accurate.
