On new Debian 12 Bookworm and Ubuntu 24.04 Noble Numbat installs, when I try running pip3 install [something] (whether that's Ansible or some other Python tool), I get the following error message:
After four decades in the broadcast radio industry, I finally convinced my Dad to join me in getting an amateur radio license this summer.
In the US, there's a huge community of amateur radio operators, or 'Hams' for short. There's a whole history to how they got that name, but to me, radio's a lot of black magic.
Throw on top of that the fact that Hams are always slinging around weird terms like QRT, using morse code—or as they call it, CW—and they call themselves weird things like NK7U!
But we cut through all that jargon and learned the basics—well, I did. My Dad went the 'Extra' mile and ran through all three tests, relying on his 40 years of radio experience! We both have licenses now (I'm KFØMYB, and my Dad's KFØMYJ) and made our first contact. Here's a video documenting that entire journey (up to the point I sent out my first QSL card!):
In 2009, a company in South Africa proved a homing pigeon was faster than an ADSL connection, flying a 4 GB USB flash drive to prove it.
Besides IEEE's speculative work, nobody's actually re-run the 'bird vs. Internet' race in over a decade.
Now that I have gigabit fiber, I thought I'd give it a try.
I published a video with all the details—and even more background on the graceful birds used in the experiment—over on my YouTube channel:
If you've ever had to transfer a file from one computer to another over the Internet, with minimal fuss, there are a few options. You could use scp or rsync if you have SSH access. You could use Firefox Send, or Dropbox, or iCloud Drive, or Google Drive, and upload from one computer, and download on the other.
But what if you just want to zap a file from point A to point B? Or what if—like me—you want to see how fast you can get an individual file from one place to another over the public Internet?
Soundproofing is... kind of an art. It's not as simple as buying something and slapping on your walls. And the word 'soundproofing' is a bit of a loaded term.
You could mean deadening sound, so you can record podcasts with that signature radio sound. Or you could mean isolating a room from outside noise, which is an entirely different process. Or you could work on reducing resonance, echo, or just certain frequencies.
In my case, I wanted to build kind of a 'sound cocoon' in the middle of this space, so I could record any time, day or night, even if my AC is running.
I recently had a server with some bandwidth limitations (tested using scp and rsync -P), where I was wondering if the problem was the data being transferred, or the server's link speed.
The simplest way to debug and verify TCP performance is to install iperf3 and run an iperf speed test between the server and my computer.
On the server, you run iperf3 -s, and on my computer, iperf3 -c [server ip].
But iperf3 requires port 5201 (by default) to be open on the server, and in many cases—especially if the server is inside a restricted environment and only accessible through SSH (e.g. through a bastion or limited to SSH connectivity only)—you won't be able to get that port accessible.
So in my case, I wanted to run iperf through an SSH tunnel. This isn't ideal, because you're testing the TCP performance through an encrypted connection. But in this case both the server and my computer are extremely new/fast, so I'm not too worried about the overhead lost to the connection encryption, and my main goal was to get a performance baseline.
