The book itself is five hundred pages. Printed double-sided and two a page, it's manageable.

Improvements would be to have page numbers in the table of contents instead of blue hyperlinks; an index in the back instead of a repeated ToC; and some minor typos like `&emdash', `f $' as a notation, and `{: definition' text.

It's an exciting work because between Visual Category Theory Brick by Brick and its reading lists, Category Theory Illustrated promises to fulfill the author's intent to "stay in the middle of the spectrum."

Front-load your mistakes as soon as possible; wisdom finds its voice in experience.

As a junior, round out the rest of CS with practica like formal methods, operating systems, compilers, or even (simulated) quantum computing. Volunteer in the labs for light website duty and software "practice" (source control, automated builds, CI pipelines).

As a pivot, consider mechatronics (engineering) and business. You've already acquired the bulk of computer science ideas; domain knowledge (for yourself) is important: electronics & feedback control systems, accounting & business plans.

Unsure how the pivot will work since you're already three years in, though. Internships would be good this year and the next.

New comment by turtleyacht in "Genesis, U.S. Department of Energy wants to build a single national AI platform"

turtleyacht — Sun, 14 Jun 2026 19:01:05 +0000

It's probably better to have distributed inefficiency than centralized inefficiency. Local fixes for local conditions. You can't get that if your ticket joins a single national queue.

Cloud providers don't merge separate companies' infra just because the same templates are used. There is a reason for providing compositional primitives but also allowing "duplicate" setups.

Every serious lab is going to need a hard charger checking in with #GovOps. Infra utilization and research delivery are orthogonal: world-class utilities can exist alongside experiments that got mired in technicalities (tech debt, outages, and unexpected transitive dependencies).

The thing about programming is it can be done with tape [1], birds [2] and textiles [3]. It happens to mostly be done on machines.

Mainline branch games. A "proof of worth" scenario is a terrible situation.

Why not keep the JIT and let it evolve alongside the new framework?
