I was pretty impressed by xtool by @kabiroberai.
It can build iOS apps on Linux machines. 🤯
I'm building a macOS app lately, so I told my agent harness to plan and implement macOS support. It took some rounds to get right, but it works. 🥳

Being able to sense the edge of your capability and use titration to keep yourself at just the right balance of effort and comfort is an immeasurably useful meta-skill that applies to every type of growth.

“When you do something, you should do it with your whole body and mind; you should be concentrated on what you do. You should do it completely, like a good bonfire. You should not be a smoky fire. You should burn yourself completely. If you do not burn yourself completely, a trace of yourself will be left in what you do.” — Shunryu Suzuki
Took me years to understand this quote deeply and apply it to my work. I kept making stuff I hated and thought I wasn’t cut out for this or that. But the peace you get from this pride in your work — it doesn’t come from an egoic place at all. It comes from exhausting all the possibilities that came up during the creation process, exploring them all, thinking them through, applying the skills you have so you’re pushing up against their edges, to make the best thing you can make *at that time* with the resources you have and the skills you possess. To give your all and know that no corners were cut, and to put utmost care and attention into the details.
The times I’ve hated my work the most, it wasn’t because the work was actually bad. It was because I know I could have done better. I could tell I was living halfheartedly, and thus creating half-heartedly. It was a cowardly thing to do, and I can say that even with self-compassion, because the hardest person to lie to is always yourself. I might be able to fool others, they may say my work is good, they may offer me money for it. But I can never fool myself, because I know even when others don’t, when I am working at my own edge and when I am not. And working at my edge is the only way I can grow — as a person, and as a creative.

As part of our goal to make MLX a great research tool, we're expanding support to new languages like Swift and C, making experimentation on Apple silicon easier for ML researchers.

MLX is an array framework for machine learning research on Apple silicon. MLX is intended for research and not for production deployment of models in apps.
Feeling a little old today, as I'm turning 100000₂ years old. But happy binaversary to me! 🎂 I'm excited to see what the next 32 years will bring. – at Lisbon, Portugal

Excellent job @gregheo and team 👏
Swift Macros gets to be featured first in the Apple’ Platform State of the Union at #WWDC23. One of the examples:

As seen before with @k_katsumi’s Swift Power Assert. 👏👏👏

Such a cool idea for the community from @FlightyApp!
Already helped @klemensstrasser and me to figure that we’ll be on the same flight from FRA!
#WWDC23 🧑🏼💻👨🏼💻
Who’s Going to WWDC? 🫧🎉
We made a fun little community site! See who is coming, explore your route, and make new friends.

Shout out to @parrots for setting up & updating this little website. ☺️
Hey folks, I‘ll be in the bay area from June 2nd to 8th for WWDC, so mostly down in Cupertino – even tho I didn’t get a golden ticket. 🎫 Looking forward to meet old & new friends. Hit me up if you want to catch up!
Finally could give Google’s Bard a first shot, via VPN because EU 😒 Lengthy conversation, discussing a coding problem, making slow but steady progress. Internet access to docs isn’t quite impressive yet. Hallucinations all over.
One advantage of this approach of multiple independent if-statements in individual code lines is that git blame becomes a virtual layer of documentation for your code. This makes it easier to understand retrospectively, _why_ this code exists.

Do I know anyone at GitHub who can help me put me in touch with the owner of an apparently dormant organization? I'd like to get a hold of the name.
