For a long time the Thinkpad has been widely regarded as the “Rolls-Royce of laptops”. Since 2003 one could argue that Rolls-Royce is no longer the Rolls-Royce of cars [1]. The way that IBM sold the Think business unit to Lenovo and the way that Lenovo is producing both Thinkpads and cheaper Ideapads is somewhat […]

In late 2013 I bought a Nexus 5 for my wife [1]. It’s a good phone and I generally have no complaints about the way it works. In the middle of 2016 I had to make a warranty claim when the original Nexus 5 stopped working [2]. Google’s warranty support was ok, the call-back was […] I’ve just attended a lecture about improving memory, mostly about mnemonic techniques. I’m not against learning techniques to improve memory and I think it’s good to teach kids a variety of things many of which won’t be needed when they are younger as you never know which kids will need various skills. But I disagree […] 10 years ago I first blogged about getting glasses [1]. I’ve just ordered my 4th pair of glasses. When you buy new glasses the first step is to scan your old glasses to use that as a base point for assessing your eyes, instead of going in cold and trying lots of different lenses they […] I was asked whether it would be safe to open a link in a spam message with wget. So here are some thoughts about wget security and web browser security in general. Wget Overview Some spam messages are designed to attack the recipient’s computer.

Due to the potential issues I refused to collect the computer and insisted on performing the work at the office of the company in question. Hard drives are vulnerable to damage from vibration and there […] I’ve recently had some discussions about backups with people who aren’t computer experts, so I decided to blog about this for the benefit of everyone. Note that this post will deliberately avoid issues that require great knowledge of computers. I have written other posts that will benefit experts. Essential Requirements Everything that matters must be […] The Need for Speed One of my clients has an important server running ZFS. They need to have a filesystem that detects corruption, while regular RAID is good for the case where a disk gives read errors it doesn’t cover the case where a disk returns bad data and claims it to be good (which […] I recently had to setup some Linux workstations with 802.1x authentication (described as “Ethernet authentication”) to connect to a smart switch. The most useful web site I found was the Ubuntu help site about 802.1x Authentication [1]. But it didn’t describe exactly what I needed so I’m writing a more concise explanation. The first thing […] Just over a month ago I ordered a new Nexus 6P [1]. I’ve had it for over a month now and it’s time to review it and the Samsung Galaxy S5 Mini I also bought. Security The first noteworthy thing about this phone is the fingerprint scanner on the back. The recommended configuration is to […] |
