It had just occurred to me that the ssd drive on my computer that suddenly died a few days ago, and seems unrecoverable, had the keys to my bitcoin wallet. Argh!!! My bitcoins lost forever?
It took a few minutes for me to wake up enough to remember that in a moment of wisdom, a month or 2 ago, I did backup the keys to another drive. Whew. Disaster averted, calming down. I just wish I could get back to sleep.
You know how you sometimes buy an album for one song, and when you listen to the album you don't pay much attention to all the other songs? And then sometime later one of the other songs will strike you, for whatever reason, and you realize that all along this song is actually much better than the song that you bought the album for in the first place?
That happened to me this morning with this song. The instrumental arrangement building up to the singing is amazing. They do some interesting tension build-up and release – I'm going to have to look up the chords to see how they do it.
Elsevier is taking down papers from Academia.edu
Lots of researchers post PDFs of their own papers on their own web-sites. It’s always been so, because even though technically it’s in breach of the copyright transfer agreements that we blithely s…
Another article I stumbled upon in my morning surfing. It's an interesting idea, instead of life beginning in an "RNA world" which is thermodynamically improbable, it may have begun in a "peptide-RNA world" where peptides and RNA co-evolved. Apparently the primordial peptides would eventually evolve into the amino-acyl tRNA sythetases, important enzymes that determine the genetic code in all living things today. It's an attractive idea since it becomes easier to see how these early interactions of peptides and RNA might eventually evolve into the genetic code.
