Restoring new iPhone from backup. The iPhone USB port is capable of 10,000 MB/s. The included USB cable is capped at 480 MB/s. The restore is capped at 50-70 MB/s ... bottlenecked on single-core CPU encryption. Sitting unused? 10 cores, hardware-accelerated encryption... 🤬

(My bad, I mixed up bytes and bits. The port can do 1,250 MB/s, the cable can do 60 MB/s, but even with the faster not-included cable the restore is capped at 50-70 MB/s by shitty single-threaded CPU-bound software.)

Lab employees really be like "if anybody builds it, everybody dies", and then proceed to build it
ANTHROPIC BUILDS BIOLOGY LAB TO PUSH AI INTO DRUG DEVELOPMENT Anthropic has quietly established a Bay Area wet lab, moving its life-sciences ambitions beyond computer simulations and into physical biological experiments. The company wants Claude to direct laboratory robots with limited human intervention, potentially accelerating research into rare and traditionally ā€œundruggableā€ diseases. Anthropic says it will focus on preclinical research rather than clinical trials, avoiding direct competition with pharmaceutical companies.

VCs adopting the lead gen tactics of horny men on Grindr.
Going to YC demo day and just changed my profile to say ā€œAC in office and homeā€.

The Cursor blog post about their system design came out ~5 days ago. The presumably very busy CEO of a $200b company has already written a full implementation, in Rust, that scales better than GitHub. What a time to be alive!
Git at Scale (by cursor) has been one of the most interesting blog posts i've read in a while. It came right when I was frustrated with Shopify's internal git system. As an exercise, I've implemented it over the weekend as open source. It's a single rust binary that you can point at any S3 type object store. It uses WAL and CAS primitives and requires no other data store. It also implements bundle-uri so large git repos (like our mono) are very fast to download as a chain of static bundles. Also comes with basic familiar UX. github.com/tobi/walgit

there will be no chairs, no tables, everything on the menu will be priced 2x what it should be, and no matter what you order the barista will rudely tell you they are out (or it’s not ready yet)
open a bay area coffee shop called us-west-1.

i… worked on adding beneficial ownership to the onboarding API for years… and… he just… ruled it out.
Today, @FinCENnews issued a final rule that permanently removes the requirement for U.S. companies and U.S. persons to report beneficial ownership information. FinCEN today also announced that it will delete previously reported information by U.S. persons from the beneficial ownership information database.

An angel investment sent me a SAFE to sign via Google Workspace eSignature request, addressed to my GMail address. I searched & couldn't find an email, push notification, shared google doc, nothing... Turns out GMail marked Google Workspace's eSignature request's email as spam.

Building software by prompting agents without ever reading or editing the code directly isn't actually a new thing. It's just called being an engineering *manager*. We have decades of experience about how to be effective as engineering managers. It is a different skill, though.

We cannot allow the outputs of models trained on the knowledge commons to become protected IP
Several companies are attempting to enclose human knowledge. A lot of parallels here to the enclosure of land.

Ok it took 1.5mo, I’m impressed at Anthropic’s restraint.
Time for the classic Anthropic tale: "We couldn't *possibly* release this powerful tool. That's irresponsible. [5 mins later] Now that OpenAI has released their equally powerful tool, we must ensure *responsible* people are in charge, by releasing our own powerful tool."

and somehow people think there will be no software jobs left? the stakes are higher not lower.
software engineering in 2026: - your package manager is compromised - your cloud provider blocks your account - github itself is hacked software is solved

For years I’ve maintained that TurboTax is cheaper, faster, and *gets better tax outcomes* than most tax accountants. This is just game over.
Tax season is here and a connector is all it takes to make @claudeai way more useful. Checkout what we just shipped: Connect TurboTax or Aiwyn Tax (formerly Column Tax) to Claude to estimate your refund, see what you may owe, and get a better understanding on the forms before you file.

Lyft Line was $2 to/from anywhere in San Francisco, and advertised as ā€œcheaper than Muniā€! (The real cost? You had to fist bump the driver and overhear someone from Airbnb gossip loudly on the phone about some reorg.)
those of you who never worked in tech during zirp will never understand this era. $5 ubers, $3 door dash lunches, enough scooters you could(and did) fill the bay. we were living like those post war boomers in million dollar homes paying $30 in property taxes. you could demand that your ceo opine on politics in #general and would go on strike if he forced you to work. you couldn’t walk down south park without tripping on a term sheet. we had so much money we were printing code on paper and sticking it in a vacuum sealed rocket launcher into space just for kicks. one click checkout was enough of an idea to burn $10m a month, wework was buying wave pools, you could buy mattresses at a loss, you could get a juice packet squeezer for $700. the zuck was surfing every day in hawaii.

Exactly this.
Worries that software developer jobs are going away are backwards. There is SO MUCH software to build right now, that previously wasn't possible (uses AI directly) or wasn't cost-effective (too niche). We're going to have more developers, and orders of magnitude more software.

A real-life ā€œI happen to have Mr LcLuhan right hereā€ moment.
Replying to @boazbaraktcs
I'm former general counsel of Army, former Undersecretary of Army, former Undersec of Defense. Not sure if that makes me a nat sec "expert." But @nabla_theta interpretation is the right one, IMO.

Many friends are worried about intelligence becoming commodified, capital ruling over all, and getting stuck in the permenant underclass. And yet a16z VCs with unlimited access to capital are desperately seeking *someone else* to vibecode for them.
