Review: Mayonnaise

A common question I’m never asked on a regular basis is: “What sort of mayonnaise should I put on my burger?”  So in an effort to answer this clearly important question, I have decided in this blog post to review two common mayonnaises that I put on my burgers (between the burger and the bottom of the bread roll, if you must know) which are both available from a leading brand of supermarket close to where I live.

Non-domain MIT Kerberos logins on Windows 10

Note: The article here requires features that don’t appear to come with the Home edition of Windows 10, such as the Group Policy Editor.  These steps may well work on previous versions of Windows, but I haven’t tried it out on them.  This article assumes you’re familiar with setting up and administrating an MIT Kerberos KDC and password server.

Blast from the Past: Usborne Computer Books from the 1980s

For those of you who grew up in the 1980s, you  might remember the series of titles published by Usborne Books about what would be considered quite esoteric subjects today, from how to program in BASIC on your favourite home computer, to writing adventure games, and even how to write Z80 and 6502 assembler (and yes, I had a copy of the last two books!)

As various parts of the computer press have stated this week, Usborne have made PDFs available of these books for free download, which you can find here.  There is also a blog posting on how the books came about here.  (Even now, I’m still amazed they even published the book on assembler programming back then!)

Perhaps one day I should port the adventure game that’s described in “Write your own Adventure Programs for your Microcomputer” to something like Inform…

DNSSEC zone re-sign today

I’ve signed or re-signed all my domains with new more secure RSA/SHA-256 keys today (and adding some domains that weren’t previously signed).  I’m going to leave my old signing keys in for a while so you shouldn’t notice the changeover, and remove them in a few days when the new DS and DNSKEY records have had a chance to propagate to the wider Internet.

(For those of you unfamiliar with the concept of DNSSEC, it is a way of using encryption to verify that DNS lookups on the Internet, which convert names such as to IP addresses and vice-versa, are genuine and are not being spoofed from an unauthorised server.)

Update: Old keys now gone from the server.
