anordalon Defensive Programming

Excellent writeup and intro to the underdiscussed topic of offensive programming, and how DefP and OffP are not contradictory (any more than graceful fallback and rejection of bugs has to be), but rather applies to different categories of errors, with that crucial line of defense inbetween.

anordalon Using Emojis in Mathematical Notation

Why is math restricted to single-character identifiers in the first place?

energy = mass · lightspeed²

↑ As you would do in programming.

anordalon RPi Compute Module 4 is here

Yes, it has PCI Express!

anordalon Pijul: A intuitive VCS unlike Git that's based on sound theory of patches

> you can "unapply" (or "unrecord") changes made in the past, without having to change the identity of new patches (without "rebasing", in git terms).

So I the identity of a patch doesn't depend on history? Nice! I wish git was like that. In fact, every time I rebase on master, I wish so.

anordalon H.266/Versatile Video Coding (VVC)

Nobody mentioning EVC? Worth a read for anyone concerned about patent licensing:

https://en.wikipedia.org/wiki/Essential_Video_Coding

There are 3 video coding formats expected out of (former) MPEG this year:

So this isn't necessarily the successor to HEVC (except that it is, in terms of development and licensing methods).

anordalon Tesla produces its millionth car

Meanwhile, the number of teslas in Norway passes 50 000:

anordalon Hunstable Electric Turbine can produce up to 3x the torque of other motors

If you exclude hybrids, 99.999% of EVs don't have gearboxes (unless you count single-speed ones), despite media labelling them as "automatic".

As mentioned, Taycan and the preprod Roadster are exceptions, and those are also the two exceptions I know.

anordalon The Tandberg Way [video]

Wow, this explains a thing or two … I happen to work for one of those spin-offs he didn't mention (Appear TV).

I've never seen it written as a list like this, but it made me nod a lot. We have changed in some ways, but I feel the basic spirit lives on at Lysaker.

The best parts of this till-now unwritten culture is also something we strive for, in one way or another. Take communication: A colleague and I are going to hold a technical meetup … some time next month, but we won't reveal the theme yet.

anordalon Dissatisfied with Docker

... then I suppose Selfdock is for you.

* Does not give or require root.

* Fast: Does not write to disk.

* Fast: Does not allocate memory.

* No daemon.

anordalon Flying-V: Flying long distances energy-efficiently

Are the wings at the back doing anything useful so far aft of the center of mass, uh, behind the rest of the craft?

anordalon When it comes to privacy, default settings matter

When it comes to everything, default settings matter.

anordalon Build2, a Cargo-like dependency and build manager for C/C++

Sounds like what Meson is.

Meson can download other Meson projects. From anywhere (no special repo). And you can use that as a fallback for pkg-config (best of both worlds).
