Back in 2007, I passed the CompTIA A+ exams. Since then, there have been a few changes to the way these exams work. Unfortunately, CompTIA haven’t done a very good job of explaining it all; it makes volume licensing seem clear and simple by comparison! In brief, if you currently have the A+, Network+, or […]

VDSL
I’ve recently swapped ISP, from Zen to Andrew & Arnold. More specifically, I had an ADSL line from Zen, and I now have a VDSL line from A&A; this uses FTTC (Fibre To The Cabinet), which BT have just deployed in my local exchange. I’m happy with the new service, and it’s definitely faster than […]
Scareware and Spamhaus
Scareware is normally just a minor nuisance, assuming that you know how to get rid of it without paying any money. However, I’ve now come across a new wrinkle: it can get you blacklisted, so that you can’t send email.
Integer overflow
I’ve been looking at a server that has Progress OpenEdge installed (10.1C). I’ve found a bug in this recently, and it’s useful to be aware of this if you use the same software. More generally, it’s something to be aware of if you write any computer programs, so that you won’t make the same mistake.
Word Recovery
I’ve come across a few Word documents that have got corrupted, so I get an error message when I try to open them:
Protecting passwords
When I created accounts with Facebook and LinkedIn, both websites asked me for my email password to help me find people I know. The idea is that they can log into my email account, go through my address book, then search their own database for people with matching email addresses. That would certainly be convenient, […]
RAIDers of the lost sleep
Early in my career, I noticed an error when I rebooted a server, saying that one of the RAID drives had failed. The server was able to keep running, but the drive needed to be replaced, so one of my colleagues came over with a new one. The drive was hot-swappable, so he was quite […]
Fake virus warnings
Someone called me earlier, because she had a big virus warning on her screen. This was actually a hoax (a web page trying to install malware), and it’s useful to be aware of it so that you know what to recognise. I identified the website which was responsible, but it’s now been taken down. So, […]
SSL: Adding a SAN to a UCC
“Hey, witch doctor, give us the magic words!” (The Cartoons) One of my servers has an SSL certificate from GoDaddy. More specifically, this is a Unified Communications Certificate (UCC), so it can have up to 5 domain names. I originally registered 3 names, and I recently needed to add a 4th. The good news is […]
4 on demand
Someone contacted me because she was trying to watch 4od (Channel4 on demand), but she couldn’t get past the age restriction screen.
