Things get heated when it’s time for Wes to check-in on Mike’s functional favorite, F#, and share his journey exploring modern .NET on Linux. Plus your feedback, combining ruby and rust, and the latest scandal with JEDI.Links:Emacs Feedback from DJ — Another point for the show is a soft intro to functional programming. Wes mentioned Emacs because of the packages supporting Clojure development when he started with that. Elisp seems to be fairly intuitive and well documented, as a little functional language its own right (correct me if I'm wrong)--this makes for a soft intro to FP. Most of my coding has been in the space of embedded systems and low-level languages--not much functional programming to be had. This show has gotten me curious about FP, which is quite old in concept, and getting implemented nicely in modern languages. For me, I still rely heavily on special Vim keys that are not mapped in evil-mode, which causes some paper cuts. However, elisp makes it easy to customize the desired UI functionality with very short programs/elisp statements in a config file. It's quite a refreshing exercise for someone like me. artichoke/artichoke: Artichoke is a Ruby made with Rust — Artichoke is a platform for building MRI-compatible Ruby implementations.

In Pentagon Contract Fight, Amazon Has Foes in High Places - The New York Times — Experts thought the contract for the Joint Enterprise Defense Infrastructure, known by the cinematic acronym JEDI, would go to Amazon Web Services, the dominant player in the field of cloud computing. They did not count on two developments: an extraordinarily aggressive public relations and lobbying campaign by Oracle, one of Amazon’s competitors, and the hostility of Mr. Trump to Amazon and its founder, Jeff Bezos.

Linux's regular filesystem disk cache is very predictable; if you do disk IO, the cache will relentlessly grow to use all of your free memory. This sometimes disconcerts people when free reports that there's very little memory actually free, but at least you're getting value from your RAM. This is so reliable and regular that we generally don't think about 'is my system going to use all of my RAM as a disk cache', because the answer is always 'yes'. (The general filesystem cache is also called the page cache.) This is unfortunately not the case with the ZFS ARC in ZFS on Linux (and it wasn't necessarily the case even on Solaris). ZFS has both a current size and a 'target size' for the ARC (called 'c' in ZFS statistics). When your system boots this target size starts out as the maximum allowed size for the ARC, but various events afterward can cause it to be reduced (which obviously limits the size of your ARC, since that's its purpose). In practice, this reduction in the target size is both pretty sticky and rather mysterious (as ZFS on Linux doesn't currently expose enough statistics to tell why your ARC target size shrunk in any particular case). The net effect is that the ZFS ARC is not infrequently quite shy and hesitant about using memory, in stark contrast to Linux's normal filesystem cache. The default maximum ARC size starts out as only half of your RAM (unlike the regular filesystem cache, which will use all of it), and then it shrinks from there, sometimes very significantly, and once shrunk it only recovers slowly (if at all).
