I've recently dragged all of my DNS records from Site5. It only took me six years to finally get off that godawful hosting service. In retrospect, keeping a better track of all DNS records would not have wasted time. Then again, I would not be a sysadmin if I wasn't…Read More

I suppose you may say all of this can be just as easily be done via systemd service config files. Well, yes and no. Yes, it can be done. And, no, not as easily. Not even close. Because systemd sucks by design. But this is a subject for another post.…Read More

This is an update to the IMDb parser I wrote years back. From time to time IMDb makes small changes to their setup that break my script. This time they decided to start blocking curl, or so it would seem. Even using a fake user-agent string doesn't help. But wget…Read More

Detecting and measuring this issue is crucial to maintaining the quality of these models and avoiding…Read More

Sooner or later it will happen: you type something after which you expect a password prompt then, as a reflex, you type the password. However, you fat-fingered the first command, and your password ended up in clear text in your shell history, likely in the system log, and who knows…Read More

Here's an oldie from two years ago that reared its ugly head on Pocket: Starting Your Day on the Internet Is Damaging Your Brain, by Srinivas Rao. The author presents his personal opinion that reading stuff online in the morning is damaging your brain. Supporting evidence? Sure: a bunch of…Read More

Just a quick collection of notes on - rather than a definitive guide to - setting up an SSH chroot jail on RHEL 6. The same should work on RHEL 7 and unrelated flavors. For the most part.

The ownCloud file sharing application has been around for some time now, but somehow evaded my attention. My limited imagination makes me say "think of it us Dropbox hosted on the server in your basement".
