> Just the four letters D U N E, which are exactly the same shape but rotated 90 degrees. It's an incredibly simple and effective design.

Gosh I've seen that so many times before and yet never really looked at it until now.

When I went to my first computer fair as a teenager, I saw the Sun Microsystems booth and was blown away by the fantastic logo. As I had never seen a Unix machine before, I didn’t know what to do with the computers on display, though.

The very first Unix I was exposed to was from Sun; I remember seeing the logo on their servers and thinking that those were the most beautiful computers I had seen (which isn't much because I had hardly seen any servers before that). I still remember that one of those came with a key (forgot whether to turn it on or lock the power button panel?)

Didn't Sun computers run Irix? Is Irix Unix?

IRIX was SGI, not Sun (and anyways yes, it's a Unix).

Thanks for clarifying. I always thought these other named systems were Unix-like but not Unix but without going all recursive like GNU with the naming

The history of UNIX is complex...

(https://en.wikipedia.org/wiki/History_of_Unix)

Suns ran Solaris, of course.

SunOS was BSD-ish originally, then around 1994 they shifted to a more SVR4 variant and rebranded to Solaris. I think Solaris 2.x was SVR4 and Solaris 1.x was BSD retronaming of what was SunOS named earlier.

It's been a while so I may not have the numbers quite right.

Anyway, there was some overlap in nomenclature, so a version bump of the SunOS naming (and Solaris numbering) implied a shift from BSD-ish to SVR4-ish, as I recall.

(And I worked for Sun for a while after that, and used Suns a ton around the shift)

"SunOS is the kernel, Solaris is the distribution as a whole" was how I was always told it went. Solaris 1.x used a SunOS 4.x kernel, Solaris 2.x and upwards used SunOS 5.x. Version synchronicity was achieved by jumping from Solaris 2.6/SunOS 5.6 to Solaris 7.x/SunOS 5.7 in 1998 when UltraSPARC support was introduced. Of course Solaris 11.x/SunOS 5.11 was the last version.

Some Unicode variants:

ᑐ ᑌ ᑎ ᑕ

ᑐ ᑌ ᑎ ᕮ

⊃ ∪ ∩ ⊂

Edit to add one more...

⋻ ⋃ ⋂ ⋳

I imagine most people are aware but the second variant you have there is essentially what was used for the most recent movie: http://www.impawards.com/2021/posters/dune_ver16_xlg.jpg

There were a lot of "DUNC" jokes about the poster, like that the main character was named "Dunc". (Real Dune heads may have some "well, actually" thoughts about that.)

I reckon Dune fans find all sorts of deeper meaning in the hit B-52s song "Private Idaho".

Ah, as if raked into the sand. Brilliant.

OMG the DUNC joke predates the new movie.
