Tee hee! Back in the day, one of the points I made to the old farts was that I had passed the 20 WPM exam and had my K6BP call to show for it, but refused to use the code on the air until the requirement was gone. Nobody spat at me or punched me out, the worst that ever happened was a poor behaving slim using my call and a postcard from the ARRL observer who thouht it was me.

WSPR tells you when communication paths are open between two points at a specific frequency and S/N ratio. This is useful but does not span the extent of research that HAARP is directed to. One of the most interesting things about HAARP is that it can incite the formation of radio-reflective regions in the ionosphere. That takes a lot of power.

I wonder if it's that as readers got faster, they have less time to deal with errors from disks that were crap to start with, so errors that have been there all along are now causing visible issues.

I remember a study that found there were problems caused by writing CDs at slower speeds on hardware designed to write faster -- causing more write errors. I've always written disks at the fastest available speed, which might be why I never ran into that issue. (Tho I still have an old 4x unit should I ever run into it.)

Commercial disks are pretty durable, as you say (unless exposed to weather, then they fall apart fairly quick). The only commercial disk I've seen fail were bad out of the box. But burnables, not so much. Mine have done well (my oldest ones are still readable) but I lived in the desert. Dampness and CDRs do not play well together, as they're not completely sealed around the edges, so I'm not surprised by tales of woe.

I still use CDRs and DVDRs for sneakernet to the DOS machine that doesn't speak network or USB, and occasionally for a specific type of backup (movie or album) but no longer routinely use them for system backup. I can get a whole stack of DVDs on a single 128GB flash drive (not to mention backup is much faster and needs far less babysitting), and per the torture tests I've read about, flash drives beat everything else for durability (retaining data through all manner of abuse; one even partially survived being shot).

And until recently I was still using them for live CDs for testing OS distros, but along came that bootable-flash-drive app and now I have 40+ distros on a single flash stick, plus a place to save files convenient to whatever I'm testing.

I never did acquire a Blu-Ray, tho I suppose now that prices have gotten sane I'll pick one up just so I have it if I need one. Which might be never at the present rate (I don't buy BR movies, so what is it good for? burned BR are reputed very unreliable, failing in as little as six months.)

The significance of this is Elon Musk, who is the self-driving Uber of dot.com billionaires and is the hero of our times.

Well, I knew Steve Jobs well enough, and have met a few civilian astronauts and a bunch of other rich people. None of the others seem to have done so much for the long-term future of the human race as Musk has in leading the path to more affordable spaceflight.
