Debian: RcppSimdJson, Opinionated IkiWiki and More

Dirk Eddelbuettel: RcppSimdJson 0.0.4: Even Faster Upstream!
A new (upstream) simdjson release was announced by Daniel Lemire earlier this week, and my Twitter mentions have been running red-hot ever since as he was kind enough to tag me. Do look at that blog post, there is some impressive work in there. We wrapped up the (still very simple) rcppsimdjson around it last night and shipped it this morning.
RcppSimdJson wraps the fantastic and genuinely impressive simdjson library by Daniel Lemire. Via some very clever algorithmic engineering to obtain largely branch-free code, coupled with modern C++ and newer compiler instructions, it results in parsing gigabytes of JSON parsed per second which is quite mindboggling. For illustration, I highly recommend the video of the recent talk by Daniel Lemire at QCon (which was also voted best talk). The best-case performance is ‘faster than CPU speed’ as use of parallel SIMD instructions and careful branch avoidance can lead to less than one cpu cycle use per byte parsed.

Jonathan Dowland: Opinionated IkiWiki
For various personal projects and things, past and present (including my personal site) I use IkiWiki, which (by modern standards) is a bit of a pain to set up and maintain. For that reason I find it hard to recommend to people. It would be nice to fire up a snapshot of an existing IkiWiki instance to test what the outcome of some changes might be. That's cumbersome enough at the moment that I haven't bothered to do it more than once. Separately, some months ago I did a routine upgrade of Debian for the web server running this site, and my IkiWiki installation broke for the first time in ten years. I've never had issues like this before.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
