Best terminal these days? Plain old mac? Warp? Ghostty? iTerm? Something else? I'm looking to switch from plain old mac. I use ohmyzsh already so I don't need anything it can handle.

“I’d say at least 50% of my prompts contain a screenshot.”
Same. A lot of overlap with my workflow (context, Wispr flow, screenshots, etc) and findings. I still use Claude more but really need to switch to codex.

Anyone have a lightweight BI tool they like? Something like blazer but a bit more:
• no limit on query duration
• not crazy $$$
• saved reports/checks
• saved SQL snippets
• AI integration for query generation
• preferably not hitting live data

New (to me) settings in Zed is 👨🍳 💋. I really want to switch to zed and this is today is my quarterly attempt. If you are using it as your primary, let me know any tips/tricks especially related to ruby/node.
I'm hoping autocomplete is as good as cursor or good enough.

Kicking the tires of cloudflare workers this morning via wrangler. Pretty sweet! I'm using it to cache some API requests to reduce thundering herds to the origin. Anyone using workers? What for? How is it going?

Take money off the table. Whether its a tender offer in a startup or your own bootstrapped company with profit. It's good to get a cushion and you don't have to be perfect. Totally agree.

I'm adding allowed domains to flipper cloud. Put in a domain, any time someone signs up via regular signup or oauth if their email matches they get auto-added to your organization.
Saw it first in slack but I think notion and others support this now. Really easy way to onboard.

Wired: 3 saas apps making 7, 6 and 5 figures in revenue.
Tired: 3 saas apps taking turns struggling with various traffic patterns.

For some reason I didn't want to switch from default screenshots on mac to clean shot. How wrong I was! I've been on clean shot for a few weeks and its totally worth it. Just give in and get a setapp subscription.

Tiny little feature I love in flipper cloud: daily activity emails. Easy to follow what others are doing like new flags and changes.
It's opt-in on your profile. I've been using it for a while and just enabled the flag for everyone.

Today I moved something that was $1k/mo on heroku to railway and it seems like it won't even cost $100/mo. Now I'm starting to think about moving all my apps entirely there.
If anyone wants to talk me out of it, do it now.

Moved another piece of infrastructure to @railway tonight for box out and put cloudflare in front of flipper. Always get nervous with changes like this so might as well batch them up. :)

How we designed Flipper Cloud to never take your app down
The first hesitation most people have with a cloud-based feature flag service is assuming that their feature flags checks will now require a network connection to said cloud. Many do, but ours doesn't.
When I considered starting Flipper Cloud, my overriding concern was how can we ensure that we never
