TFTP is fine for LAN, but very inefficient for sending bulk data over the Internet.

To keep things as simple as possible, TFTP sends one packet at a time, waiting for a response before sending the next packet. If your ping is 50 ms, the that’s 20 whole packets per second. (That’s assuming zero packet loss, otherwise it will be even slower.)

For historical reasons, the packet size is locked to 512 useful bytes. That puts the transfer speed at 10 kB/s (80 kbps), which is faster than dialup but not by much.

Even in death, I serve the Omnissiah.

Right idea, wrong number. Satellites in low Earth orbit are typically moving at about 7-8 km/s, depending on the exact altitude. The speed required to get from the surface to deep space (i.e., the “escape velocity”) is 11.2 km/s.

The escape velocity for the Earth is 11.2 km/s. If you shoot a cannonball upward at that speed, it’ll have enough energy to completely leave Earth and never come back.

I understood that reference. ♥️

Insurance never covers damages from war, because that’s a good way to bankrupt the insurance company. Even they don’t have infinite money.

I was skeptical, but the source checks out.

Canada was an open participant in the 2001 invasion of Afghanistan, and a clandestine participant in the 2003 invasion of Iraq, which kinda sounds like picking a fight to me.

OK, now explain why you can’t find a decent ISP in a major American city. (That’s right, it’s because of monopolies and enshittification.)

Were you talking to John Carmack or John Connor?

What? This is a press release from the California Attorney General literally taking about what they are doing in court right now.

How do you go from that to “thEy’Re DoiNg NothIng”?

I never knew bands could reproduce by mitosis.

They want US$7,000 for a chair and some monitor support arms? I want to try one, but not that much.

This is just for city of Los Angeles, which is a small portion of Los Angeles county, let alone the entire state of California.

NVR = Network Video Recorder. It’s the box that has the hard drive(s) to record all the video streams coming in from the cameras over WiFi or Ethernet.

I have a Reolink setup that’s entirely air-gapped. No app required, just configure everything through the NVR unit.

Ah, the classic “all eggs in one basket” strategy.
