  they absolutely are not pacing
How would you know if this release is absolutely the best model they were capable of releasing as soon as possible, or an inferior model, several releases short of what they’ve achieved months ago?
gricardo99··on If a Tesla Cybercab fleet were profitable, Tesla wouldn't sell you one
you could make this same argument about any business and any mechanism that raises outside capital to expand.

If McDonald’s restaurants were profitable, they wouldn’t sell franchises. Except it’s been an incredibly successful way to raise capital and expand, for both franchisees and McDonalds.

If company about to IPO were a great investment, they wouldn’t IPO. Except the stock market has been an incredible mechanism for company and capital growth.

gricardo99··on A Selection of Los Alamos Rolodex Business Cards
Incredible. I was curious to see what I could find for one of the business card:

Dr. Ronald Moskowitz, FerroFluidics (cool name).

Took me down a bit of a rabbit hole. Turns out the guy was a bit of a fraudster and was sentenced to 8 years in prison for securities fraud[1]

gricardo99··on I like 'em thick: an apology to my English teachers
It was such a joy to read something clearly written by a human, for humans, by someone who takes pride and spends effort in their writing.

Reading this article felt like a breath of fresh air, like a vice had been released from my head. Not just the broader point about our increasingly slop-filled world resonated with me, but the writing itself felt like it just flows effortlessly.

I guess I’ve been suffering for too long, pouring over claude code jargon-filled responses and going in circles trying to understand its convoluted sentence construction and terminology. I think I’m burnt out on working with agents all day long…

gricardo99··on Leaving the Physical World
An incredible, lucid, and beautiful depiction of the burgeoning, inchoate world of cyberspace at the time — voicing an anxiety that echoes even louder today:

   We humans would be liberated into an Elysian condition of permanent leisure. We’d have nothing to do but hang out in our indestructible miracle-fiber jumpsuits and talk philosophy.
  Only it didn’t happen quite like that. The machines did get many of our physical jobs alright, but no one could quite figure out how to pay us   for all that hanging out.
What would John make of what’s unfolded since? Much as he envisioned and embraced, humanity poured its imagination, creativity, toil, and love into cyberspace — only for the machines to feed on it all and usher in a new, all-encompassing level of human obsolescence.
gricardo99··on Production engineering when trading billions of dollars a day [video]
there’s a move now towards 24/7 trading. I guess we’ll see how the rigors of the trading environment mesh with zero down time. I’m sure the rollout will be slow and steady.

  bad at identifying business trends
I think you’re being unduly harsh on yourself. At least by the Shopify/COVID example. COVID was a black swan event, which may very well have completely changed the fortunes of companies like Shopify when online commerce surged and became vital to the economy. Shortcomings, mismanagement and bad culture can be completely papered over by growth and revenue.

Right place, right time. It’s too bad you missed out on some good fortune, but it’s a helpful reminder of how much of our paths are governed by luck. Thanks for sharing, and wishing you luck in the future.

gricardo99··on Verizon starts requiring 365 days of paid service before it will unlock phones
That’s what I thought and did this for years. However, the major carriers do offer promotions and incentives that make the phones cheaper, sometimes significantly. e.g. of recent deal from major US carriers: iPhone 16 deal for $16/month for 36 months ($576 total) versus Apple store $699.

actually you do need another participant to take the other side of your trade. That’s not a middle man. Market makers, liquidity providers, are a key component of these markets, taking risk with their own capital (no systemic risk, no too big to fail, going to get a government is things go badly), requiring sophistication and specialization to survive in an ultra competitive environment with a high degree of uncertainty and risk exposure.

gricardo99··on Disney+ cancellation page crashes as customers rush to quit
he’s clearly commenting on how the “maga gang” is characterizing the murderer. There’s no statement directly about the murderer.
gricardo99··on Configuration files are user interfaces
With all the code syntax highlighting support as a feature, I feel it will become tempting to put code in configuration files (which some of their examples show). That just feels wrong. Code should go in code files/modules/libraries, not mixed with configuration files. If your configuration starts to become code, maybe you need to rethink your software architecture. Or perhaps KSON proves that principle to be too rigid and inferior, and leads to more intelligible, manageable software. I guess we'll have to see.

gricardo99··on How I use my terminal
The one thing pulling me towards VS code, and away from terminal workflows is Copilot and the Agent workflows. Being able to seamlessly chat with AI models and then see/review its code changes is the biggest change to my workflow and productivity in years.

I’m guessing some people already have these capabilities integrated into terminal workflows and I’d love to see a demo/setup.

gricardo99··on Tokasaurus: An LLM inference engine for high-throughput workloads
since you work on pytorch, what would you say is the best place to ask questions about general usage, trouble shooting? I’ve been struggling with a, what I would consider, a simple torchrun elastic training example, and haven’t found any good resources online. I’ve been spelunking through pytorch but have a feeling a little back and forth with someone familiar with these features would immensely clear things up.
gricardo99··on The Tcl Programming Language: A Comprehensive Guide (2nd Edition)
My favorite Tcl story is a little side note about how Tcl could have been the language of the web[1]

  the founding of Netscape   occurred at the same time I was deciding where to go in industry when I left Berkeley in 1994. Jim Clarke and Marc Andreessen approached me about the possibility of my joining Netscape as a founder, but I eventually decided against it (they hadn't yet decided to do Web stuff when I talked with them). This is one of the biggest "what if" moments of my career. If I had gone to Netscape, I think there's a good chance that Tcl would have become the browser language instead of JavaScript and the world would be a different place! However, in retrospect I'm not sure that Tcl would actually be a better language for the Web than JavaScript, so maybe the right thing happened.

Too humble Dr. Ousterhout! It would have been a far better language.

  By incorporating DyT, Transformers without normalization can match or exceed the performance of their normalized counterparts, mostly without hyperparameter tuning.

gricardo99··on Bring crypto back to currency
Interesting ideas. I think in any practical system, you'd still need some central authority that determines:

  a basket of basic, thickly traded commodities should be chosen; perhaps a basket of specific amounts of basic elements, thermal and electrical energy, and basic food commodities, priced as delivered to several large markets. 
and

  A control algorithm such as the PID loop used in process control or robotics is employed to adjust K over time.
At a minimum, those aspects of this currency would need to be flexible such that they can be adjusted over time, as needed, to maintain the currency's stability. An inflexible scheme seems like it would be doomed to failure. And yet, any tinkering could also be its demise and undermine its stability and faith in the system. It's a delicate balance.

Ultimately money is a social construct based merely on shared belief. Algorithms can used to enhance and support this social construct, but I do not see how it could wholly replace human/social interventions.

gricardo99··on The future of kdb+?

   And this is the architecture as designed and recommended by the KX consultants that you end up having to hire to “scale” 
I think this hits on one of the major shortcomings of how FD/Kx have managed the technology going back 15+ years, IMHO.

Historically it’s the consultants that brought in a lot of income, with each one building ad-hoc solutions for their clients and solving much more complicated enterprise-scale integration and resilience challenges. FD/Kx failed to identify the massive opportunity here, which was to truly invest in R&D and develop a set of common IP, based on robust architectures, libraries and solutions around the core kdb+ product that would be vastly more valuable and appealing to more customers. This could have led to a path where open sourcing kdb+ made sense, if they had a suite of valuable, complementary functionality that they could sell. But instead, they parked their consultants for countless billable hours at their biggest paying customer’s sites and helped them build custom infra around kdb+, reinventing wheels over and over again.

They were in a unique position for decades, with a front row seat to the pain points and challenges of top financial institutions, and somehow never produced a product that came close to the value and utility of kdb+, even though clearly it was only ever going to be a part of a larger software solution.

In fairness they produced the delta suite, but its focus and feature set seemed to be constantly in flux and underwhelming, trying to bury and hide kdb+ behind frustratingly pointless UI layers. The more recent attempts with Kx.ai I’m less familiar with, but seem to be a desperate marketing attempt to latch onto the next tech wave.

They have had some very talented technical staff over the years, including many of their consultants. I just think that if the leadership had embraced the core technology and understood the opportunity to build a valuable ecosystem, with a goal towards FOSS, things could look very different. All hindsight of course :)

Maybe it’s not too late to try that…

gricardo99··on The future of kdb+?

   Get a free version out there that can be used for many things…
I think this has been the biggest impediment to kdb+ gaining recognition as a great technology/product and growing amongst the developer community.

Having used kdb+ extensively in the finance world for years, I became a convert and a fan. There’s an elegance in its design and simplicity that seems very much rooted in the Unix philosophy. After I left finance, and no longer worked at a company that used kdb+, I often felt the urge to reach for kdb+ to use for little projects here and there. It was frustrating that I couldn’t use it anymore, or even just show colleagues this little known/niche tool and geek out a little on how simple and efficient it was for doing certain tasks/computations.
