Elfeed Not Support Xhtml? here's a test
if this content shows, then it means, i must use the CDATA thing and it doesn't support xhtml.
Update: yes, elfeed now fixed it! fixed on , see https://github.com/skeeto/elfeed/issues/112
by the way, elfeed is a RSS/Atom feed reader, for emacs, written in elisp. It's excellent. https://github.com/skeeto/elfeed, also on MELPA.
by the way, reddit is also switching to atom. https://www.reddit.com/r/changelog/comments/428vdq/upcoming_reddit_change_switching_from_rss_20_to/
if your blog is using RSS, you should switch to Atom, because RSS is garbage, by Dave Winer. (i think Dave Winer is one of those guys in computing industry i regard is charlatan, but i haven't ascertained my own opinion yet. (charlatan, y'know? like, those selling you snake oil, the gurus, they spread gospels and people buy it. In fact, typically a lot followers. Larry Wall, Martin Fowler, are prime examples. Typically, these guys, their golden touch, is never technical (say, a math theorem), such as say Knuth. But, they rely heavily on social things. It is via social, they get their kicks. In particular, their weapon of choice is fuzzy and cozy and mythical jargons, Unix Philosophy, KISS, defensive programing! (remember that?)! laziness is virtue of programer! (remember that?) Design Patterns! eXtreme Programing, Agile, SCRUM! Idioms! Pythonic!)) (disclaimer: this is all opinion only.)

Which Mouse to Get for Emacs
someone asked about which mouse to get for emacs
most gaming mouse have onboard memory, such that you set the buttons once, then plug in any computer it'll work. The software is usually Windows only, so you need a windows machine. (or, a virtual box might work)
but if you really want a mouse with linux api, i hear that ROCCAT mouse is famous for that.
roccat has many models. This one i think is physically/functionally best. ROCCAT Tyon Mouse
other models are ROCCAT Gaming Mouse with Linux Support
but i've not used them.
myself recommend plain logitech. I recommend any of the following, up to your preference in size, number of buttons, and whether it has spin wheel.
- Logitech G602 Wireless Gaming Mouse
- Logitech G502 Proteus Mouse
- Logitech G700s Mouse Review
- Logitech MX Master Wireless Mouse
- Logitech G600 Gaming Mouse Review
most mouses, as long as they are standard usb devices, one can also program the various buttons in X11 without the mouse itself providing means, but it's a huge hassel. One'll spend weeks and weeks reading the many many half-written how-tos.
also, a warning. Some gaming mouse REQUIRES installing and registering their “cloud” software for every computer you use the mouse in order for the button config to be remembered. Notably Razer Orbweaver Keypad. So, i generally stay away from anything Razer.
