Just a lvl 28 guy from Finland. Full-stack web developer and Scrum Master by trade, but actually more into server-side programming, networking, and sysadmin stuff.

During the summer, I love trekking, camping, and going on long hiking adventures. Also somewhat of an avgeek and a huge Lego fanatic.

  • I recently set up the whole stack (Postfix, Dovecot, OpenDKIM) on a VPS. I wanted to do it from home, but my ISP won’t provide a static IP or open ports 25/465/587 for consumer customers, no exceptions.

    It took me about two days to get everything working, but most of that was because I went in with very little knowledge of how email even actually works. If you’re looking for a learning experience, I’d say go for it. If you just want a working email setup quickly, I wouldn’t recommend it.

    I haven’t noticed any deliverability issues so far. Just make sure you have SPF, DKIM, DMARC, and PTR records all set correctly from the start.




  • You can do it from a live cd/usb just fine, but you’ll need to repeat some preparation steps (basically chapter 2 of the book) every time you boot the host.

    The way I did was to install the host (I chose Debian) on a small partition on the disk, leaving most of the space for the LFS partition. Once the (B)LFS build was complete enough that I didn’t need the host anymore, I just removed its partition and expanded the LFS partition into the now unallocated space.












  • Not intentionally, but in high school we had a test on identification of flowers and plants. The teacher was an older man and he wasn’t good with computers. He was showing pictures from the computer using video projector but didn’t realize that Windows was displaying the filename of each picture in the title bar and each picture was named e.g. “daisy.jpg”. Almost the whole class got full marks on the test except for the unlucky few who sat in the back row and had poor eyesight.
