0Tin full of spamHow to reduce spam with SPF, DKIM & DMARC

Since I set up con­tact forms on vari­ous web­sites I’ve had a slowly increas­ing volume of spam.  Not dir­ect spam sent to me, but bounces from non-exist­ent addresses that were being spamme, appar­ently from my address.  Unfor­tu­nately the spam wasn’t ori­gin­at­ing from my address, but my address was some­how picked up (prob­ably from before I secured the con­tact forms on the site) and was being used as the “reply to” address.  After some invest­ig­a­tion I heard about SPF which is an e-mail anti-for­gery sys­tem.

6Microsoft Office Excel 2010Conditional formatting for grades v targets

So, in my oth­er life I’m actu­ally a sci­ence teach­er, and as it usu­ally gets round that I’m “good with com­puters” I usu­ally get asked to have a look at a few things.  Twice in the last few months I’ve been asked if I’d set up con­di­tion­al format­ting in excel to col­our code stu­dent test res­ults com­pared to their tar­get grades.  Whilst not exactly related to the core con­tent of this site, it is still DIY tech­nic­al help so I decided to pub­lish a full set of instruc­tions here.  Enjoy…

0Wordpress LogoRich Snippets code for Mystique 2.x

In addi­tion to this site I have a per­son­al blog where, amongst oth­er things, I post recipes. I’ve recently dis­covered google’s new recipe search, and have been look­ing to imple­ment sup­port for micro­formats / microdata. Google provide a tool for check­ing your markup, called the “rich snip­pets test­ing tool”. When I tried val­id­at­ing one of my recipes, I encountered vari­ous errors, which have taken me a while to track down and resolve. … Read Full Art­icle

3windows 8 logoHow to restore a proper UI to Windows 8 & Server 2012

Win­dows 8 and Serv­er 2012 have now RTMed and as expec­ted the good old UI of desktop and start­menu has been replaced with a hor­rible new UI (pre­vi­ously called Metro).  In their ulti­mate wis­dom Microsoft have left no way to switch back to the old desktop/start menu sys­tem, but thanks to vari­ous tweaks and tools it is pos­sible to get 90% of the inter­face restored — good enough to be fully usable.  Below I doc­u­ment the vari­ous steps and tweaks required.

0Settlers IIResurrecting a very old post: VGA fix for Settlers 2

Thanks to a request by dhd in a com­ment on the down­loads page, I decided to go look­ing through backups of my old web­sites.  Below is a pos­ted I wrote around 200304 about how to fix prob­lems with run­ning the game Set­tlers 2 on Win­dows XP.  I’m pretty cer­tain the same wont work on new­er ver­sions of Win­dows sadly, but for those XP users still out there who want to play your (very) old copy of Set­tlers 2 — enjoy…

0AMD Vision Fusion Premium LogoFixed: AMD E350 crashes & invalid boot device error

I’ve had an AMD E350 sys­tem for over a year, which I use as my primary HTPC. How­ever, in that time I’ve always had oca­sion­al sta­bil­ity issues where the sys­tem would lock up, reboot, and fail to find the primary HDD. At first I put this down to the HDD — a Seag­ate Momentus XT, which was known to be unre­li­able when it was first released. Since Seag­ate released update firm­ware how­ever the drive has seemed to oper­ate fine, although I couldn’t rule it out. I also updated the BIOS of my Asus E35M1-M Pro and updated all the drivers I could find, without fully resolv­ing the issue.
