  • Peter 'CzP' Czanik ☛ Peter Czanik: Working with multi-line logs in syslog-ng

    Most log messages fit on a single line. However, backdoored Windows and some developer tools and services, like Tomcat, write multi-line log messages. These can come in various formats. For example, new log messages start with a date in a specific format. You use the multi-line-prefix() of the syslog-ng file() source to send multi-line messages as single messages instead of line by line.

    Netflix has announced

    the release of a tool called bpftop to help with the performance

    optimization of BPF programs in the kernel:

    bpftop provides a dynamic real-time view of running eBPF

    programs. It displays the average execution runtime, events per

    minimizes overhead by enabling performance statistics only while it

    is active.

This and being exposed to dozens of homebuilt computer projects inspired him to begin building his own 8-bit computer in 2010, which eventually grew into the Wire Wire Odyssey.

  • Kev Quirk ☛ I Have a Guestbook

    After seeing Manu's guestbook, I had to get in on the action, so I've decided to create my own guestbook.

    I won't go into detail about my love of the old web, and the indie web. Anyone who reads this blog regularly knows how I feel about all that. If you don't know, and you don't mind the odd swear word, you can read my essay about it.

    Anyway, last night I read about Manu adding a guestbook to his site. I think it's a fantastic idea, and it's something I've thought about in the past. But previously, this site was based on Jekyll, so creating one would have been difficult.
