Backing Up WSL Images

Igor — Fri, 02 Jan 2026 15:53:28 +0000

Originally published January 4, 2020 @ 3:19 amMicrosoft’s WSL is interesting. I’d go as far as to say that I like it. The mistake here would be to forget that your Linux image is running under Windows, with everything this entails. Making a reliable backup of this thing proved harder than I expected. I have […]

Home-Brew Ransomware Defense

Igor — Fri, 26 Dec 2025 08:18:31 +0000

Originally published December 28, 2019 @ 12:42 amThe first well-known case of ransomware was documented in 1989. The so-called AIDS Trojan was delivered on a floppy disc; encrypted data; demanded $189.00 (nearly four hundred bucks in today’s money) as a “license fee.” The trojan was quickly defused due to its reliance on weak symmetric cryptography. […]

Originally published August 22, 2019 @ 12:49 pmI can’t recall the last time I needed to convert a CD to ISO. I have four laptops and not one even has a DVD drive. It took me a while to find an external drive and remember how to do this. To avoid having to deal with […]

Exporting WordPress to Markdown

Igor — Wed, 13 Nov 2024 12:29:43 +0000

Originally published November 14, 2021 @ 2:56 amWordPress is my favorite CMS, but the complexity and security issues introduced by PHP and the database are unnecessary in some cases. Migrating to a static Web site may be a better option when it is all you need. There are plenty of choices like Gatsby, Hugo, and […]

Automatic File Backups in VIM

Igor — Fri, 16 Aug 2024 20:08:52 +0000

Originally published August 17, 2021 @ 12:09 pmHaving to undo stupid changes to config files is an unfortunate side effect of too few sysadmins supporting too many servers. The VIM editor has some built-in file backup options. However, I find these options very limited and generally not particularly well suited to sysadmin work. A solution […]

Working with SD Cards for Photographers

Igor — Mon, 17 Jun 2024 00:49:52 +0000

What do I recall from my extensive overland trips in the past few years? Not much, to be honest. It was just a blur of driving, looking for gas stations, trying to reserve camping spots or motel rooms, and – yes – joggling camera batteries and SD cards. But I learned a few tricks I’m […]

Rsync Time Backup

Igor — Thu, 19 Oct 2023 02:01:41 +0000

Originally published December 22, 2016 @ 11:06 pmThis is a simple wrapper for the awesome rsync-time-backup script by Laurent Cozic. Through clever use of hard links rsync-time-backup greatly speeds up incremental backups and saves disk space. The wrapper script is for my internal NAS environment. The script selects either production or Dev/QA NAS based on the server […]

Filesystem Synchronization with Freehold

Igor — Sat, 30 Sep 2023 20:56:13 +0000

Originally published July 8, 2016 @ 11:03 amWhenever an application description begins with phrases like “runs on anything” and “is easy to setup”, attribute such bravado to the author’s lack of experience outside his development sandbox. Freehold comes as a tarball for “any Linux” and, naturally, won’t work on most of them out-of-the-box. Documentation for freehold mostly remained in […]

Monitoring NetBackup Daemons

Igor — Wed, 27 Sep 2023 21:08:53 +0000

Originally published April 27, 2016 @ 11:22 pmHere’s an example of a script you can use to monitor NetBackup server daemons in a Linux environment. The main difficulty with keeping track of these services is that there are so many of them. What makes NetBackup reliable and rich in features is the modular nature of […]
