DIY RSS feed reads

Here’s one of the reasons to have your own permanent server: The New York Times has a daily feature called, not surprisingly, “The Daily“.  It’s a short 15-20 minute news segment, ready by 6 AM.  It’s available through Google Play Music or iTunes, but I leave for work by 6:15, and I don’t want to use up cell data downloading something that should arrive on my phone just before I leave the house.  Of course, there’s no obvious way to tell Google Play, “I know it’s there; go get it right now”.  I don’t know the iPhone experience, but I imagine it’s the same.  I want to download on my time, not on Google or Apple’s schedule.

Luckily, there’s an RSS feed for this podcast.  That, plus this simple script on my DragonFly system, means I can pull it down whenever I’m ready:

fetch -o – http://feeds.podtrac.com/zKq6WZZLTlbM | grep enclosure | cut -d ‘”‘ -f2 | xargs fetch -m

So, it’s a matter of running that script, and syncing off my own local storage, on my own schedule.  FolderSync Lite will happily sync back to my phone using sftp.

 

Near-term dports work

Rimvydas Jasinskas posted an extended description of what’s happening with dports.  There’s a significant xorg reformatting coming in ports, which is going to be absorbed into dports, but it may take some time.  There’s also an odd loss of commit rights for John Marino, who commits (frequently!) to both DragonFly and FreeBSD.  (His followup)  This all translates to some upcoming transition time for dports to accommodate these changes.

Note that if you are using dports binaries, especially on DragonFly 4.6 release, this won’t really affect you; the way dports is set up, binary sets always work.  It is interesting to hear about future work, in any case.

Significant memory handling changes in DragonFly

If you are on DragonFly -master, now is a good time to update.  Matthew Dillon has been changing how DragonFly handles locking and memory use, with differences in the vmstat structure and page coloring, some memory settings, and many other locking changes.  I am only linking to a few examples.  If you don’t want to dig through those links for performance numbers, he summarized his changes and their effects in a post to users@.
