“Never eat alone.”
I’m doing a job in Georgia at the end of the month. I’d love to meet some of my LinkedIn connections for dinner. I’ll be staying in Kennesaw, available around 6-ish on August 25, 26, and 27. Depending on how many people schedule, they may be group dinners, no guarantees of one-to-one, but it’s possible. The only rule is, no sales pitches. This is just a time for getting to know each other, build relationships, and hopefully learn from each other.
Ways to schedule:
DM me on LinkedIn
My mobile number is in the “Contact info” section of my profile
Use the “Contact Us” page at fifonetworks dot com. (“Contact us” is contacting me. I’m a sole proprietor. It’s only me).

Fiber optic cables evolved to support growing bandwidth and distance demands. Single-mode fiber uses a narrow core to transmit a single light path for long-distance, high-capacity links, while multimode fiber uses a wider core to carry multiple light paths over shorter, more economical distances.

Here is a comparison between single-mode and multi-mode fibers #datacenters #technology #sysadmin

This is a funny bit from 2013 of a client connecting to itself, that still works (on #linux):

while true; do telnet 127.0.0.1 50000; done

Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
[...]
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

This happens when the source port, taken out of range of the ephemeral ports, is the same as the destination port (50000).

Friends, it finally happened. On August 7th, 2025, the number of spamtraps intended to woo the unwary spammer rolled past the number of inhabitants in my home country of Norway. It's time for a retrospective.

Notes for August 1-10

I got COVID again this week, which made it a hard slog to go through work hours (which I trimmed a bit) and pretty much impossible to do anything. And yet, I sort of persevered.(...)

The updated #Gnome in #Debian 13 now supports importing #Wireguard .conf files directly and no longer requires you to do it manually in the terminal with nmcli. Just tested the "Import from file" option on a Wireguard config file and it worked perfectly fine,
