    Errm, Wireshark. Please bear with me.

    Wireshark is a shining example of an open source project completely and utterly crapping on the closed source competition. As a result we all benefit. I recall spending a lot of someone else’s money on buying a sort of ruggedized laptop with two ethernet ports to do the job back in the day.

    Nowdays, I can run up a tcpdump session on a firewall remotely with some carefully chosen timings and filters and download it to my PC and analyse it with Wireshark.

    OK, all so convenient but is it any use?

    Say you have a VoIP issue of some sort. The PCAP from tcpdump that you pass to Wireshark can analyse it to the nth degree. Wireshark knows all about SIP and RTP (and IAX) and you can even play back the voice streams or have them graphed so you can see what is wrong or whatever. That’s just VoIP, it has loads of other dissectors and decorators built in.

    So what?

    The UK (for example) will be dispensing with boring old, but reliable, POTS (Plain Old Telephony System) by 2025. Our entire copper telephony and things like RedCare (defunct soon) will go away.

    We are swapping out circuit switching for packet switching. To be fair, a lot of the backend is already TCP/UDP/IP that is shielded away from us proles. When SoGEA (Single Order Generic Ethernet Access) really kicks in then the old school electric end to end connection will be lost in favour of packet switching, which never fails (honest guv).

    If you are an IT bod of any sort, you really should be conversant with Wireshark.

    Borg for backup. I’m really surprised it’s not more widely known. It’s an incredible piece of software.

    Also, not really lesser known software, but a lesser known feature of file systems including the ones we use in FOSS operating systems: extended file attributes - useful to add metadata to files without modifying them.

    I’ll try to keep this to lesser known apps:

    • Catima (saves barcodes for gift cards, gym memberships, etc so you don’t have to worry about the physical card)

    • Cofi (nice timer for active guidance through coffee brewing recipes)

    • 10,000 Sentences (a language practicing app that doesn’t have a mildly threatening owl 😉)

    • OSMAnd+ Mapillary, Overlay Maps, and 3D Features (seriously, the best. I only use Google maps to get around traffic these days since, unfortunately, Magic Earth doesn’t work very well in my area)

    • Obtanium (as a gateway to lesser known software, no shipping to an app store required!)

    • RethinkDNS (an absolutely amazing piece of software that gives you fine-grained control of the domains your apps are talking to. A bit of a battery sync but it’s been a game changer for me. On my GrapheneOS setup I use it in the Google sandbox to reduce the amount of data scraping servers my Google apps can talk to)
