what's inside?
- the case for expressing bitcoin with ₿
- teach your agent the skill
- edit a screenshot
- keyboard shortcuts for typing
- list of wallets that have adopted
- many instances of ₿

Itty Bitty and his new itty-bitty sloth friend

Thanks @unslothAI for stopping by @TheAhmadOsman’s local AI meetup at @PresidioBitcoin and contributing to the plushie collection!

[Haley Berkoe @HBerkoe]

Love that you chose Cafe Francisco! They use Square and accept bitcoin. If you encourage people to pay with Cash App, that helps them save on credit card fees (0% vs ~3%). Customers use dollars (and get 5% back), cafe gets dollars, bitcoin's just the rail. Happy to show you how!

[Ben Lang @benln]

We're booking out a cafe on June 10th in San Francisco

Grab coffee, Cursor credits, meet the team, and build together

AGENTIC PAYMENTS

🤜 STABLECOINS VS BITCOIN 🤛

🏆 WHO WILL WIN? WHO DESERVES TO WIN? 🏆

@MATBALEZ INVESTIGATES

[Spiral @spiralbtc]

Meet Loupe, an AI-powered vulnerability scanner for open-source bitcoin projects. Attackers already use AI to find weaknesses. Maintainers should do the same.

Bitcoin Core, BDK, LDK, rust-bitcoin, Cashu, Jade, bitcoinj, and SRI are already onboard.

[Ahmad @TheAhmadOsman]

The first Local AI Get-Together was a massive success

This pic is missing quite a few people who left before we hit the 4-hour mark, but thank you to everyone who stopped by 💙

Local AI is very real, very alive, and apparently willing to talk GPUs, open weights, inference engines, agents, and homelabs for hours

We should do this again soon

[PBJ Podcast @PresidioPod]

.@dksf calls last month’s @bBuilderSF his favorite one yet.

In the clip below, PBJ unpacks @michaelneale’s mesh-llm and what it suggests about the future of distributed AI compute.

Timestamps:
0:00 - Builder meetup’s evolution from vibe coding to AI infra
02:44 - Mesh-LLM and the promise of decentralized compute
07:10 - New markets for distributed AI compute (e.g., intra-enterprise)
09:25 - Local AI and the return of hardware constraints

[Presidio Bitcoin @PresidioBitcoin]

Excited to host this at PB this Saturday - RSVP and swing by!

[Ahmad @TheAhmadOsman]

Bay Area people:

I got way more DMs than expected, so I’m making this official-ish

Casual SF Get-together this Saturday, May 9th

No panels
No pitch decks
No formal agenda
No fake networking energy

Just local AI / GPUs / infra / opensource / agents / homelab people hanging out

[Haley Berkoe @HBerkoe]

@TheAhmadOsman We may be able to host you at @PresidioBitcoin! The space is great for meetups (easy parking, good AV/wifi, and view of Golden Gate Bridge)

[Anthony Ronning @anthonyronning]

@TheAhmadOsman If you ever want to host a meetup while you’re here, I’m sure the beautiful @PresidioBitcoin hub in the presidio would love to have you.
