Replaced leaking capacitors on another Mac LC 475 board. I’m beginning to like it! Not a dramatic improvement, but the speaker crackle is gone.

With retro-computing projects on hiatus, I post a photo of an attic object. It came with surplus MicroVAX II, and is a Q-Bus board from 1992 labeled Super SRCC. With a 68020 and Xilinx FPGAs, it seems to be a co-processor.

There should be a dedicated word for this: Thinking about asking Siri a question, imagining the resulting disappointment, and deciding not to ask after all. As a frequent iOS user, I experience this several times daily.

Don't we just love MS Outlook? Never mind that the message deceivingly invites you to switch to "new" Outlook, which apparently has fewer functions than the old one. I'm so happy to have to use this abomination only in order to remove attachments which Apple Mail is not able to remove.

What a beautiful illustration from the MacsBug Reference and Debugging Guide, from 1993. I always wondered where the high memory is!

Not sure if anyone has used @BlueSCSI this way, but here it is: Apple Interactive TV (1995 vintage) is booting from a 7.1 disk set up previously in PB 520c, and being controlled via Timbuktu remote desktop. That also uses BlueSCSI network interface.

My wired connection has (supposedly) IP obfuscation set to off. And yet, unless I turn off iCloud Private Relay completely, it does hide the IP, leading to all sorts of problems accessing university services. How long ago was the Private Relay introduced?

I thought I'll use built-in Outlook support tool to nag MS about a) senseless prompts to update time zone (from Brussels to Berlin, adjustment of zero hours), and prompts to disable auto reply whenever one has the audacity to open Outlook while on "vacation" […]

How did I miss that there exists a Severance TV show podcast? Covering both seasons? I had to search for it on a whim while preparing for a trip, if you believe it...

Like every year since 2015, I spend part of my last days in the office working on the CATS institute report for the alumni and friends. It's a chance to review the year, and pick the most amazing stuff. This is probably the most fun thing I do at work!
