velominati··on Bender: AI's 'Existential' Risk Is 'Fake' [video]
Am I the only one that thought this would be an AI-generated video with Bender, the alcoholic robot from Futurama? Could somebody please make that?
velominati··on Jeff – Jev-compatible 0.8B decision models, trained at home, ~30 ms
Typesafe has been quite about the underlying technology behind Jev. Given the speed and cost my hypothesis is that it doesn’t input tokens the way that LLMs do, ie iterating over every word and drawing the connections between each. That is an o(n^2) problem which is why LLMs are so expensive as they scale.

Wow - Google does not even bother to show benchmarks of these models compared to the frontier and Chinese labs - only against previous versions. I'm not surprised. Having worked there for years it was amazing just how inwardly looking the company is.

velominati··on Sam Altman's response to Molotov cocktail incident
It's never OK to physically attack someone like this. Full stop.

Separately; Sam's belief that "AI has to be democratized; power cannot be too concentrated." rings incredibly hollow. OpenAI has abandoned its open source roots. It is concentrating wealth - and thus power - into fewer hands. Not more.

velominati··on Rowing Across the Atlantic Ocean; My Experience (2021)
This sounds like an incredibly foolish expedition. They took a boat to sea without practicing basic seamanship procedures (person overboard drills), an inaccessible life raft, and no practice as a crew. That’s not adventurous, it’s reckless.

Money helps, but it's neither necessary nor sufficient.

I've been at a company that many considered to have excellent design and that received a lot of attention here (Heroku). There was a culture that permeated the company around beautiful design and what I would call "maker excellence". It was a place where people who liked building great things (both engineers and designers) felt at home.

velominati··on How People Get Rich Now
Thanks for posting the PG wealth tax article. It is a highly flawed analysis.

First wealth appreciates over time. So if your wealth appreciates at 15% / year, and the govt. taxes it at 1%, the net effect is growth rate is slowed to 14%. With these assumptions, someone starting with $1mm in wealth ends up with $2.6 billion after 60 years!

Second - PG ignores that most wealth tax proposals have a high minimum wealth - in the $50mm range. So there is no early compounding of the tax. Adding this into the model, the wealthy founder ends up with $3.3 billion after 60 years.

With no wealth tax, this hypothetical founder ends up with $4.3 billion. So, yes the government has taxed a total of ~ 25% over 60 years, but the founder ends up quite wealthy.

velominati··on Airbnb’s Stunning IPO
Plus of the 10% of the shares soldo, most were to institutions with an understanding that they are going to hold it "long term" (i.e. which may be just a few months). Part of the IPO road show is for the company to select investors that believe in the company and who will be "good" shareholders.
velominati··on Airbnb’s Stunning IPO
It is a misconception that when a company IPOs and the stock pops, that the delta is money left on the table. The vast majority of the shares are sold to institutional investors. There are explicit or implicit lock-up periods in place. And most of the pre-IPO investors will typically have a 6-month lockup. So if 10% of shares are sold in the IPO and 10% of those shares are actually trade-able, only 1% of the total stock is liquid. That can lead to very large price swings (i.e. the pop).

velominati··on Modeling a Wealth Tax
This isn't the correct way to model wealth tax's effect on founder equity. Paul's model doesn't account for the changing value of equity over time.

When a startup was at the seed stage and worth say $5mm, a founder with a 50% stake would be paying $25,000 / year with a 1% tax. If the company grew and received a b-round of investment valuing it at $150mm, with the founder diluted to 20% ownership, the wealth tax on the $30mm in equity would be $300,000. As you can see the tax rate changes over time significantly.

There would likely be some unexpected consequences. Founders would re-consider sky-high valuations during funding rounds because of the effect on their tax rate. Startups may consider generating real cash-flow earlier on in order to issue dividends to their shareholders to cover the wealth tax instead of selling shares. If equity holders did sell shares to cover the tax, there would be a more liquid secondary market, which could make "house-of-cards" startup more apparent early on.

velominati··on Cloud Run – Newest member of our serverless compute stack
I'll post the example source code here tomorrow after the talk (still tweaking it).
velominati··on Cloud Run – Newest member of our serverless compute stack
I'm doing a talk at Next tomorrow about just that. For now you are probably better of using Ruby on App Engine, assuming you need to use redis as a cache. Another new feature that we launched today is VPC Connectors, which allow Cloud Functions and App Engine to connect to servers/services in a VPC.

Cloud Run will have support VPC Connectors soon (it is supported, we just haven't wired up the API/UI). After that, its your choice, they run on similar infrastructure so you just need to decide if you want to live in containerland or source code land.

velominati··on Cloud Run beta pricing
Hi. I manage App Engine (the original "serverless" product at Google).

This is a very understandable concern, given the importance of having a platform on which you can rely.

Contractually Google Cloud provides a 1 year notice before discontinuing (or making backwards incompatible changes) to products. This is for generally available (GA) products. Cloud Run is in beta, so technically it could be decided not to bring it to GA. This is why some conservative orgs tend to wait for products to be GA before releasing them.

From a technical perspective, Cloud Run was designed to be highly portable and idiomatic. If the service were discontinued (or you just didn't like it), you should be able to take your container image, and run it anywhere else. Odds are you would be using some other Google Cloud Services, so you would likely want to run in an environment with low network latency to Google Cloud (Compute Engine and Kubernetes Engine being obvious candidates).

From a historical perspective, I'd say that Google Cloud goes above and beyond in supporting older products. App Engine is about to hit its 11th anniversary. We are still running PHP 5.5 apps and backporting security patches to the runtime, despite the language losing community support 3 years ago. We are still turning down an old product called "Managed Virtual Machines", which has now been in a deprecated (but running) state for longer than it was GA!

From an emotional perspective, I think that Google is eyed with a lot of suspicion for turning off products. Google Reader - enough said. But as someone on the thread pointed out, Google Cloud is a very different business from the rest of Google. Google (!cloud) is a consumer company at a scale where if a product matters when it hits a billion users. Google Cloud is an enterprise company. Scale still matters, but not in the same way it does in consumer.

I can't wait for hacker news folks to try Cloud Run. Its an awesome product.

velominati··on Beta release of PHP 7.2 in the Google App Engine standard environment
Hi. I'm the PM at Google Cloud on the Second Generation runtimes.

This is based on gVisor (https://github.com/google/gvisor), but it does not use the ptrace sandboxing that is in the mainline open source project. Our First Generation runtimes (aka nacl) were based on ptrace. In our informal testing we have observed the Second Generation runtimes to be about 20% faster than the First Generation. I don't have benchmarks on how it compares to a raw VM.

These new runtimes are capable of multithreading, so long as the language is capable of it. And you will need to use an instance larger than the default (F1 / B1) to have access to more than one thread.

velominati··on Knative – Kubernetes-based platform to manage modern serverless workloads
It isn't limited to functions. Knative can run containerees, or with a build system take full app code and deploy it as a container.
velominati··on Node.js is now available on App Engine standard environment
Another PM on App Engine here.

Historically supporting a language on App Engine required modifying the languages libraries to work on proprietary parts of Google infrastructure. This entailed a decent bit of effort on our part, and also meant that some apps & code wouldn't execute correctly.

We now use technology based on gVisor (https://github.com/google/gvisor) in production for App Engine standard. This allows us to release new language runtimes unmodified. Node.js support is the first runtime based on this new stack.

We completely agree that we should be releasing support for new languages & major versions more frequently...

velominati··on Magic Leap Raises $461M from Saudis
+1. The inability to invest against startups and other privately held companies seems like a big economic inefficiency. It would be a counter force to these sorts of nose bleed valuations.
velominati··on Magic Leap Raises $461M from Saudis
It's possible. The Apple Newton is a great case study of a good idea that was too early. And the inability to minitiarize it sufficiently to fit in a pocket was one reason for it's failure. A few years later the Palm Pilot was much more successful because it could fit in your pocket, especially the baggy jeans that were fashionable in the late 90's.

Webvan's model hasn't yet been validated. The local delivery startups and offerings are still losing lots of money. If anyone can make it work it will be Amazing, but it has yet to be validated as a profitable business.

velominati··on Magic Leap Raises $461M from Saudis
This is great evidence of the greater fool theory: https://en.wikipedia.org/wiki/Greater_fool_theory

I’ve heard some second hand anecdotes about Magic. Apparently they have one big technology advance, which is that they’ve solved the eye tracking and vertigo challenges of AR. These are hard and not to be underestimated. However the company is supposedly a mess internally - with huge management and political issues. This isn’t surprising - I’ve been in a number of early stage startups and by default they are a mess. Add on top of that billions of dollars of funding and no customers or sales to anchor the company to reality, and its easy to see how AR can become “Alternative Reality”! Further evidence - their recently released headset photos were renderings, not actual products. I genuinely hope that I’m wrong - I’d love for the amazing demo videos they’ve released to congeal into real mass market products.

Does anyone else have good data on Magic?
