  • Setting up FreePBX

    I’m setting up a FreePBX system for my house. My goal is to make it so that I can make and receive calls using a phone in the house.

    When someone calls in, they are greeted with a voice menu (IVR in FreePBX terms) which simply asks them to press 1 to talk to a human. This is done to screen out telemarketers - most telemarketers dial your house by robot, and then connect a human to the other end of the line once you pick up and say “Hello.” This is usually not an instant process, which is why you usually have to say “hello” a few times. Therefore, the telemarketers usually miss the IVR, and are greeted with silence.

  • Alphabet League of Legends Challenge

    We’ve been playing a series of League of Legends games where each game, every champion we pick must contain a given letter of the alphabet (so for the “A” game, every champion picked needs to have an “A” in the name, then for the next game every champion needs to have a “B”, and so on.)

  • Creating an SPF record

    So, you want to add an SPF record to your domain.

    First, SPF records used to be held in TXT records, but more modern DNS systems hold the SPF data in an actual “SPF” record. If your DNS solution doesn’t support SPF, then use the TXT record instead. Either way, the format is the same. Here’s a very simple example, which only allows mail sent from an IP address listed in one of the MX records for the domain example.com:

    example.com.  IN SPF "v=spf1 +mx -all"
