I was asked for advice on whether children should have access to smart phones, it’s an issue that many people are discussing and seems worthy of a blog post. Claimed Problems with Smart Phones The first thing that I think people should read is this XKCD post with quotes about the demise of letter writing […] The version of btrfs-tools in Debian/Jessie is incapable of creating a filesystem that can be mounted by the kernel in Debian/Wheezy. If you want to use a BTRFS filesystem on Jessie and Wheezy (which isn’t uncommon with removable devices) the only options are to use the Wheezy version of mkfs.btrfs or to use a Jessie […] For the Technical People This post isn’t really about technology, I’ll cover the technology briefly skip to the next section if you aren’t interested in Linux programming or system administration. I’ve been using the Systemd init system for a long time, I first tested it in 2010 [1]. I use Systemd on most of my […] I work on SE Linux to improve security for all computer users. I think that my work has gone reasonably well in that regard in terms of directly improving security of computers and helping developers find and fix certain types of security flaws in apps.

According to Google searches this is due to DNSSEC not being enabled. I’m not certain that I really need DNSSEC for this reason (I can probably make DKIM […] Yesterday I installed the wp-spamshield plugin for WordPress [1]. It blocks automated comment spam systems by using JavaScript and cookies, apparently most spammers can’t handle that. Before I installed it I was getting hundreds of spam comments per day even with the block spam by math plugin enabled. Now I’ve had it running for 24 […] My last problem with BTRFS was in August [1]. BTRFS has been running mostly uneventfully for me for the last 4 months, that’s a good improvement but the fact that 4 months of no problems is noteworthy for something as important as a filesystem is a cause for ongoing concern. A RAID-1 Array A week […] The Verge has an interesting article about Tim Cook (Apple CEO) coming out [1]. Tim says “if hearing that the CEO of Apple is gay can help someone struggling to come to terms with who he or she is, or bring comfort to anyone who feels alone, or inspire people to insist on their equality, […] |
