Times are changing and @donuxcom needs to change as well. After 6 years and 100+ of products built the old way doesn’t work anymore

it’s in gemini, just create it in ai studio. oh, that’s for your personal google one account. for workspace you need gemini business. no, not gemini advanced, that’s ai pro now. unless you need ai ultra. oh agents? you do that in spark actually. no, not gemini api managed agents, that’s different. for coding use jules. unless you mean the agentic ide, that’s antigravity. no, that’s the old antigravity, download the new one. actually gemini cli is being deprecated, use antigravity cli. no the flash model is smarter than the pro model. unless you need pro. if it’s video, use flow. no, flow uses veo. no, nano banana is images. actually that’s in gemini now. unless you’re in search, then it’s ai mode. no, research is notebooklm. anyway it’s all very simple.

@heyandras Waiting to test this one 😍

[Giustino 🍩 @jubstuff]

@pbakaus I saw that the way I talk with Claude is not effective with Gemini or Codex and vice versa. It takes me a bit of time to adjust and get the most out of another model. Or maybe it’s just all in my head 🤪

[Giustino 🍩 @jubstuff]

The answer has always been “pick one and keep using it”

[Dan ⚡️ @d4m1n]

the answer was Cursor all along 😃

while we're messing about with our Claude Codes and Codex CLIs people that just kept using Cursor & optimized their workflows seem to be winning 🤦‍♂️

maybe it's my FOMO, but the other day I asked about which model to use between Opus 4.6 and Codex 5.3
People were like "use both".
I'm thinking, how tf can I use Codex 5.3 in Claude Code and also not pay OpenAI 200 bucks too.
Turns out most of them just use Cursor 🤷

Jokes aside, I took these Christmas completely off from work, and I feel energized. The first four days anxiety surged and I couldn’t stop thinking about it, but then I relaxed and it was way better

[Giustino 🍩 @jubstuff]

I couldn’t work these holidays, my wife trained the dog to guard the MacBook

@joshwoodward @GeminiApp Ability to delete chats for workspace users

@massimuntoni @erfantalimi 1 out of tens worked out, but I was happy I did

[Giustino 🍩 @jubstuff]

All process issues tend to magically disappear with the right people, especially when you’re a small company

[Giustino 🍩 @jubstuff]

@erfantalimi @massimuntoni But at least in one scenario you're the one controlling the narrative, and you could not regret your inaction

In January we started a project with a company after 3 years(!) from our first meeting. I kept writing him every 6 months because I believed we could be of value to them

@tropianhs Congratulations!!

I was sure I read “Thanks for your attention to this **dark** matter!” (Pun intended)

[Antonio Tropiano 🪳 @tropianhs]

My next small bet is a book!
"Quantum Physics for Absolute Beginners"

In the book I explain often obscure concepts such as wave-particle duality, superposition, and entanglement, and shed some light on the applications of quantum physics in everyday life

I am giving away 20 copies of the ebook FOR FREE
In exchange I look for feedback and a review once the book is out

To grab a copy, comment below and/or send me a DM so I can give you the book link!

Thanks for your attention to this matter!

As simple as it gets:

a. realize that the world won't crumble if I open an email, and I can just have more data to solve the issue, even if it's a difficult conversation

OR

b. wait for a moment with more energy (usually the morning) and make it the first thing I do

[Giustino 🍩 @jubstuff]

I still get anxious just at the idea of opening an email from a client sometimes. At the beginning of my journey I thought I'd just overcome it. But then I understood that these swings of energy are part of myself, and learned to recognize the symptoms and act accordingly

[Giustino 🍩 @jubstuff]

@theandreboso I know, I remember! But I'm not joking, there should be some psychological element at play here, that makes you relax about the rest of things you need to do, and focus on the things you want to do

[Giustino 🍩 @jubstuff]

@p_millerd Thank you for sharing this 😊

[Giustino 🍩 @jubstuff]

@p_millerd So writing in private alone (without the book part) wouldn’t do it in your opinion?
