Let me know when you have enough demand to make it multiple full-time jobs. I’ve been making notes for a few years now about all the best patterns and principles for designing complex systems and your language + engine more or less hits all

Sotolongo's lineage is Twitter observability -> Google streaming -> Snowflake Dynamic Tables, which is a declarative, relational, query-optimizer-centric tradition. Marz's lineage is Storm -> Trident -> Rama, which is

Secure channels can still be jammed. Undetectability is a fundamentally different goal than secrecy.

I strongly agree with that last statement—I hate using agents because their code smells awful even if it works. But I have to use them now because otherwise I’m going to wake up one day and be 100% obsolete and never even notice how it happ

Today I gave a lecture to my undergraduate data structures students about the evolution of CPU and GPU architectures since the late 1970s. The main themes: - Through the last two decades of the 20th century, Moore’s Law held and ensured tha

It definitely wasn’t a waste of time! I passed JLPT N1 back in 2014 after ~6 years of mostly Anki-based studying. Did Heisig’s RtK first and then mostly played old Japanese console games that I was familiar with. Never opened a JLPT study g

Miraikan is one of our favorites, been there like 3-4 times with my son. The current exhibit that turns quantum logic gates into a DJ game is really innovative but they only give you like 5 mins which is barely enough time to figure out WTF

For all the disparagement of “fact regurgitation” as pedagogical practice, it’s not like there’s some proven better alternative. Higher-order reasoning doesn’t happen without a thorough catalogue of domain knowledge readily accessible in yo

Your last statement misses the mark—of course the brain is the root of human intelligence. The error is in assuming that consciousness is the primary learning modality. Or, as you put it, “arguing semantics”. From my own personal experien

Your analogy to PHP developers not reading assembly got me thinking. Early resistance to high-level (i.e. compiled) languages came from assembly programmers who couldn’t imagine that the compiler could generate code that was just as perform

People choose to hold non-yield-bearing assets when they believe the returns offered by current investment opportunities are not sufficient to justify the risks. It is the miracle of modern capital markets that enables almost anyone to quic

Another principle that builds on the other two, and is specifically applicable to Java: - To the greatest extent possible, base interfaces should define a single abstract method which allows them to be functional and instantiated through

I don’t completely disagree, just like 90%. Junior developers typically aren’t taught the design patterns in the first place so they dig deeper holes rather than immediately recognizing that they need to refactor, pull out an interface an

I’m required to teach DSA in Java, so I lay down a couple rules early in the course that prohibit 95% of the nonsense garbage that unconstrained OOP allows. Granted, neither of these rules is original or novel, but they are rarely acknowl

I started teaching undergraduate computer science courses a year ago, after ~20 years in various other careers. My campus has relatively low enrollment, but has seen a massive increase in CS majors recently (for reasons I won’t go into) so

I can’t stop thinking about this exact notion. The main reason we don’t always use stuff like TLA+ to spec out our software is because it’s tedious AF for anything smaller than, like, mission-critical enterprise-grade systems and we can gen

That last line is exactly what I was thinking. Find an expressive language and then progressively formalize your workflows in DSLs that enforce correctness by design, not through layers and layers of natural language “skills” and deadweight

Still basically relies on feeding context through natural language instructions which can be ignored or poorly followed? The answer is not more natural language guardrails, it is in (progressive) formal specification of workflows and accept

7 years ago, my graduate distributed systems professor required everyone to complete his projects in Elixir because it was trending on HN. It was my first functional language and after getting over the initial hump I fell in love with it. N

Love this example. I started putting my Kindle highlights in the SRS—no prompt or anything, just the quoted text verbatim—and the effortless periodic review essentially burned the quotes in my memory for easy recall in moments when they wer

Yes, all behaviors should be implemented like definitions in category theory: X behaves like a Y over the category of Zs, and you have to recursively unpack the definition of Y and Z through about 4-5 more layers before you have a concrete

You’re right, you don’t know! When I worked on a nuclear aircraft carrier, I learned that the people working down in the reactor spaces got significantly less radiation exposure than the people working on the flight deck. My ship was ported
