Sometimes we can’t have nice things, just because the nice thing is difficult to state clearly in words. For example, the record low daily high temperature for this date is arguably just as meaningful as the record high daily high. But the weatherman never tells us the record low high, probably because it would confuse…… Continue reading The oldest living former X
I’ve read a number of lists of frequently misspelled words, and I always end up thinking “Really? That doesn’t match my experience at all. If your methodology says that supersede is misspelled more often than its, then I think you need a new methodology.” Of course, context matters. Professional writers misspell different words than internet…… Continue reading My list of frequently misspelled words
I claimed in a previous post that, for a given atomic mass number, there is one and only one nuclide that is immune to all forms of beta decay. It occurs to me that I was probably technically wrong, especially since I made it clear that I considered atoms with different nuclear energy states to…… Continue reading Beta-stable nuclides with the same mass number
Or: Why IPv6 failed (This post is about Internet Protocol, the communications protocol that the Internet runs on.) (Rant alert! I’m trying to be nice on this blog, but I can’t seem to make this post much less mean than it is.) The successor to IPv4 is not IPv6. It might be IPv7, or it…… Continue reading IPv6.001
How many ways are there to put an extra “thumbnail” or “preview” image inside a JPEG (.jpg) image file? This isn’t just trivia. One problem with thumbnails is the possibility that they might be neither updated nor deleted when the main image is edited. If you’re not careful, your edited JPEG file could contain a…… Continue reading JPEG thumbnail formats
What primordial radioactive nuclides (isotopes) still exist in the Earth’s crust? To figure that out, we might need to know the original abundances of various nuclides in the matter that now makes up the Earth’s crust. I haven’t found good data on that. But it’s pretty easy to calculate what the abundances would have to…… Continue reading Is there any niobium-92 left?
Plain text extensions is an obsolete feature of the GIF (version 89a) image format. Essentially, it allows an animated GIF to have ASCII text frames, as well as the usual graphical frames. As far as I know, it was pretty much never used at all. The only GIF file with plain text extensions that I’m…… Continue reading GIF plain text extensions
