The Missing Semester of Your CS Education – Revised for 2026

- first of all, you need to know how to manage your own digital information. Even though it's taken for granted that a CS/CE freshman knows this, well, in my experience, that's usually not the case also for many PhD... Information management isn't just a taxonomy of files and dirs; it's also about evaluating, for example, what happens if the software you use for your notes is discontinued, or if your photo gallery disappears, and so on, and acting accordingly knowing your SPOFs and how to mitigate them;

- then you need to know how to write, in the broadest sense, which includes mathematical notation, generating graphs, "freehand" drawing like simple CAD, and formatting your work for various purposes and media, whether it's emails, theses, reports, or general messages. This is where teaching LaTeX, org-mode, R/Quarto, etc comes in. It's not "advanced" is the very basic. Before learning to program and no, Office suites are not an answer, they are monsters from a past era, made to makes untrained human with little culture to use a computer for basic stuff instead of typewriters, a student is not that;

- you need to know how to crunch numbers. Basic statistics are useful, but they're largely stuck in another era. You need to know how to do math on a computer, symbolic computation, whether it's Maxima or SymPy, doesn't really matter, and statistical processing basis. For instance, knowing Polars/Plotly/* at a minimum level are basic skills a freshman should have at a software/operational level, because they should be working in these environments from day one, given that these are the epistemological tools of the present, not paper anymore.

Then you also need to manage code, but in the broadest sense. A dSCM is also for managing your own notes and documents, not just software, and you need to know how to share these with others, whether it's Radicle or Forgejo or patches vua mail doesn't really matter, but this family of software needs to be introduced and used at least at a basic level. A DynDNS services should be also given so anyone could try to self-host the services they want.

Knowing how to communicate is an essential skill, and it's not about using Gmail or Zoom... it's about learning how to self-host basic communication services. It doesn't really matter if it's XMPP, Matrix, or Nostr, but the concept must be clear, and understanding the distributed and decentralized options we have today is vital. A student needs to learn how to stand on their own two feet, not on someone else's servers.

These are basic IT skills that aren't "advanced" at all, despite what many people think, or "sysadmin-level" and so on; they're simply what a freshman should have as someone who loves knowledge and wants to get their hands dirty.
