Happy 42nd birthday to the The Hitchhiker’s Guide to the Galaxy video game

H2G2 art box – from Wikipedia

Today, 42 years ago the famous Infocom game The Hitchhiker’s Guide to the Galaxy got released.

There is a bit of confusion on that date, as the above Wikipedia page mentions November 1984 for the USA and January 1985 for the EU.

Those are the time frames the boxes reached the public, but the actual release on 1984-09-14 is documented in [Wayback/Archive] The Infocom Bugs List: The Hitchhiker’s Guide to the Galaxy.

I got reminded last year by [Wayback/Archive] Charles Hawn on X: “Hitchhiker’s guide to the Galaxy was released 41 years ago today on Sept 14, 1984. Written by Steve Meretzky and Douglas Adams. It was #Infocom’s 14th game. What a bad day! As the story begins a bulldozer is preparing to level your house. DON’T PANIC! #Commodore64 #Commodore #C64 …” who was lucky to have the original complete box including button, pocket fluff and fleet (see picture below).

I wasn’t so fortunate back in 1984: I had entered secondary education not long ago, my parents didn’t believe in computers at all, I hardly got any allowance and had no idea where you could by software locally.

An original copy of the game (either Apple II or IBM) is still on my wish list, as well as the InvisiClues hint book mentioned at [Wayback/Archive] Charles Hawn on X: “@odinisamu It took me days to finally figure out how to get the babel fish into my ear to translate Vogon to English. It was before the internet and walk through so you just had to keep trying different things or pay $14.95 for the hint book sold by Infocom. I got this a few years ago. …”

How does Linux really handle writes?

Posted by jpluimers on 2026/09/14

Note that actual writes to SSD can be just as slow as to HDD. [Wayback/Archive] How does Linux really handle writes? really well describes writes to HDD which equally holds for other operating systems (like Windows) with the exception that the SYNC systems calls are named differently.

From the article:

Here’s how the write really works.
  1. you echo "foo" > bar.txt
  2. the operating system copies “foo” into a special place in memory called the page cache
  3. (microseconds later) the operating system tells you the write succeeded
  4. (asynchronously, up to 30 seconds later) the operating system actually writes “foo” to disk
If your mental model was “files live on disk”, the above is shocking. I mean, I used to think that the disk write happened immediately, but actually it can happen 30 seconds later!

Via (hopefully I can archive this link later)
