Planning on doing this after giving every employee their own Hermes instance.

Working theory is just to provide a folder that rsync’s. Nothing fancy.

[Mike Maples, Jr @m2jr]

Has anyone created an internal GitHub but for skills and prompts (not code) that can be hosted internally to a company and have non technical contributors?

[Ian Sefferman @iseff]

@nirkouris was one of the Israeli soldiers embedded in my birthright trip 20+ years ago.

Good guy back then. Good guy now. 🇮🇱

[Yossi Farro @FarroYossi]

Wrapped Tefillin with @nirkouris for the first time in his life at New York Tech Week.

Nir co-hosted the event together with one of Israel’s top banks, IDB, a financial institution worth over $10 billion. He also flew in 12 Israeli founders to connect them with American investors and help build the future of Israeli innovation.

In the middle of one of the biggest gatherings of founders, builders, and innovators, we took a few minutes to connect to something timeless.

Watching another Jew put on Tefillin for the first time is always powerful.

Especially in a room focused on shaping the future, while reconnecting to a tradition that has guided the Jewish people for thousands of years.

[Ian Sefferman @iseff]

This is nice. Hermes has become my daily agent. Use it for almost everything now.

iOS app when???

[Nous Research @NousResearch]

The next evolution of Hermes Agent is here!

Introducing Hermes Desktop: everything you love about Hermes, now native on your machine.

First demoed in Jensen's GTC keynote, it's now in public preview.

[Ian Sefferman @iseff]

We built this internally months ago in a couple days.

[Keith Rabois @rabois]

Every enterprise CFO is going to demand this.

[Ian Sefferman @iseff]

at this point the models are getting so good that i don't think anyone can tell one from the other.

[Ian Sefferman @iseff]

Companies that define their growth in headcount terms are so screwed

[Ian Sefferman @iseff]

hot take: i still don’t believe skills are all that useful nor insightful.

[Ian Sefferman @iseff]

never go places with the bridge and tunnel crowd.

always go to places where you are the bridge and tunnel crowd.

[Ian Sefferman @iseff]

dangerously close to giving every goodbill employee their own personal hermes agent with shared company context.

feels like the future. and employee perk of how many personal tokens you get per month, too.

[Ian Sefferman @iseff]

This is the way. Except don’t lock yourself into one lab.

Use @t3dotcodes to do this and choose the best model/harness for the job.

[Alex Finn @AlexFinn]

You need to set up this Codex system I have

Been taking advantage of their new remote features and my productivity has 1000x'd

I have one device (Mac Studio 1) as my main dev machine. That's where all code is written

Then all my other devices (iPad, iPhone, Mac Studio 2, 2 Mac Minis) are nodes I send commands from

No matter which device I'm on, no matter where I am in the world (could be at the grocery store, in bed, Japan, on the toilet, by the pool, on the road using FSD) I have code written in one place

Made coding big projects SO much easier

Here's what I'd do if I were you

Choose one device you have (preferably a desktop device like Mac Mini or Mac Studio)

Make this your main dev device. Make sure it never turns off and never goes to sleep

Go into Codex app then settings on that device. Go to connections > control this Mac. Turn that on

Then go into every other device you have, mobile, desktop, whatever, and go into Codex settings and enable control other devices

Also download Tailscale on every device. This will allow you to create a private network that will allow your other agents (OpenClaw or Hermes) to jump between computers and make changes when necessary

You now have a super powered AI private network where you can code or get work done from any device anywhere in the world

Promise this 1000x's your productivity

Peak narrative-based capitalism

[Sawyer Merritt @SawyerMerritt]

SpaceX in IPO filing: "We believe we have identified the largest actionable total addressable market in human history. We estimate that our quantifiable TAM is $28.5 trillion, consisting of $370 billion in Space from space-enabled solutions; $1.6 trillion in Connectivity across $870 billion in Starlink Broadband and $740 billion in Starlink Mobile as well as additional opportunities in enterprise and government; $26.5 trillion in AI across $2.4 trillion in AI infrastructure, $760 billion in consumer subscriptions, $600 billion in digital advertising, and $22.7 trillion in enterprise applications. For illustrative purposes of sizing our addressable market opportunity, we exclude China and Russia from our global estimates."

[Ian Sefferman @iseff]

@josealb @esrtweet That’s assuming the humanoid can do ANY task as well as a task-specific robot.

I think that’s wishful thinking. And even if so, why wouldn’t I want four arms and three legs and eyes in front and back? Seems like I could much more done that way.

[Ian Sefferman @iseff]

Even if very lazy, this is a great example of why I am bearish on humanoid robots.

Like @esrtweet says about *nix programs: small and simple robots, connected together, only getting more complex when absolutely required.

[How Things Are Manufactured @fastworkers6]

A KEUREGG for eggs in the morning. Lazy but low key want it.

[Ian Sefferman @iseff]

The hill I’m willing to die on is that hospitals — not insurance cos (and certainly not clinicians) — are the root of the cost issues in American healthcare.

It’s not even close.

[@jason @Jason]

They updated the most legendary chart on twitter

What stands out?

[Ian Sefferman @iseff]

@aviel probably right. text-completion -> code-generation was a very good pathway.

[Ian Sefferman @iseff]

collectively, we’ve significantly over-indexed on coding agents as the killer app, and under-indexed on the 99.99% of other knowledge work

[Ian Sefferman @iseff]

i know nothing about cards. but i know this launch vid slaps. and i know whatever @mfg is into is prob legit.

mazal on the launch!

[Trove @Trovexyz]

It was never just about the cards…

It was about who you shared them with
It was about the moments
It was about the feeling
It was about being a kid
It was about who you became
It was about what you held onto
It was about the memories you made

Today we launch Trove to bring that feeling back.

[Ian Sefferman @iseff]

imo, the #1 reason to have your own personal claw/hermes is specifically to have memory that isn't behind one lab's walled garden.

moving from claw to codex effectively locks you into openai.

[Ryan Carson @ryancarson]

Starting to think about moving away from OpenClaw and into Codex for my executive assistant/chief of staff.

Is anyone else considering this, or if you've done it, how's it going for you?

However, there's one major problem where you can't authenticate multiple Google Workspace accounts, which is often necessary for EA stuff.

@odd_joel Moshi is great. I’m a fan and user. Thanks for it!
