Why do so many German web sites end with "24"? Do Germans need reminding that the internet doesn't close at 8pm and all day on Sunday?
Every subject should have a series like this.
My best advice for better technical communication is to *stop* doing two things:
- Introducing the topic with general facts
- "Tell 'em what you’re going to say, say it, then tell them what you said"

There's such a huge difference between reading a paper about an algorithm/system/etc., and trying to implement it yourself.
I read the paper and think "I get it".
I try to implement it and realize I didn't get it *at all*.

Most visual programming languages make limited use of the visual channel — the program structure is represented visually, but not much else. Usually the shapes and colors they use have an abstract (symbolic) meaning, not a concrete one.

One of the best decisions I've made in the past few years is to stop treating side projects like work projects.
E.g.
- "doesn't something like that already exist?"
- "you shouldn't implement that yourself"
Both make sense at work, but wrong attitude for side projects imo.

Interesting to think about this when teaching programming. Not much thought is given to exposing kids (people) to the process of creating “serious” stuff, or seeing an expert practitioner work.

You know they'll tell you:
- what the problem is
- a high-level description of their solution
- how it compares to other solutions
…and usually in the first 2-3 pages.

In programming languages, SIGPLAN actually has an award for the most impactful systems. So I wondered — how "publishable" were papers on those systems?

If "a small set of orthogonal primitives" is good, why does *no* popular language have this?
Possible explanations:

2️⃣ It's good, but doesn't drive adoption
3️⃣ Number of primitives should be "just right" (not too big, not too small) twitter.com/dubroy/status/…
