Irreal

If you’re a Vim or Emacs user, you’ve seen a lot of jokes like this one from XKCD:

They usually end the chain with cat but sometimes, like the above, they go all the way to butterflies.

All that’s good fun if a bit whimsical, but you sometimes see serious assertions that “real programmers” use ed. If you’ve never used ed, as most of today’s programmers probably haven’t, it’s no doubt hard to understand how silly that argument is. If you’re working on a teletype, ed is just the thing. If not, it’s just masochism.

Or so I thought. Others disagree:

Dominic van der Zypen makes the case that ed is great for everyday use. I’m not convinced but you can read it and judge for yourself. I will say, though, that just because a lot of Unix development was done with ed doesn’t mean much because that development was also done on, you know, teletypes. It’s like saying that just because Sun Tzu fought with swords, today’s armies should use them too.

Regardless, it’s fun, if a bit surprising, to see someone champion ed for everyday use. If you’re running on some sort of Unix/Linux system, including macOS, you’ve almost certainly got ed installed so fire it up and see what you think.

Yeah, this is probably a joke but if there is one thing I don’t want
from Emacs, this is it.

Jeez! A guy can’t be away from the Internet for a couple of days without everything changing. One of those changes is that a new version of Emacs, version 25.3, has been released. This is an emergency release to fix a security issue with Enriched Text mode.

You can read the details in the announcement but it’s probably a good idea to upgrade even if, like me, you aren’t using the X support. I did my usual compile-from-source dance without any problems.

I’m writing this Monday night after Irma came visiting. First off, thanks to the many people who wrote—either directly or through Disqus—to send their well wishes. I appreciate your concern and good thoughts.

At the last moment, Irma shifted east onto the mainland and went up the middle of the Florida peninsula rather than up the west coast. For those of you not as intimately familiar with hurricanes as we in Florida are, that’s important because hurricanes are basically heat pumps (technically a Carnot heat engine) and once over land they lose access to the warm coastal waters that are their source of energy. The result for Tampa was a routine Category 1 or 2 hurricane rather than the devastating monster storm that Irma was promising to be.

We did lose power Sunday night and it still hasn’t been restored. Once it is, I will publish this post. I could, I suppose, connect to WordPress with my iPad and write the post directly into the control panel but once you’ve experienced the joy of writing and publishing your blog posts from Emacs, you never want to do that.

Florida officialdom is actually pretty good at dealing with these things so I expect you’ll be seeing this post soon.
