Federico Mena-Quintero: Exposing C and Rust APIs: some thoughts from librsvg
Librsvg exports two public APIs: the C API that is in turn available to other languages through GObject Introspection, and the Rust API.
You could call this a use of the facade pattern on top of the rsvg_internals crate. That crate is the actual implementation of librsvg, and exports an interface with many knobs that are not exposed from the public APIs. The knobs are to allow for the variations in each of those APIs.
This post is about some interesting things that have come up during the creation/separation of those public APIs, and the implications of having an internals library that implements both.

Dirk Eddelbuettel: RQuantLib 0.4.11: More polish
New year, new RQuantLib! A new release 0.4.11 of RQuantLib arrived overnight on CRAN; and a Debian upload will follow shortly.
QuantLib is a very comprehensice free/open-source library for quantitative finance; RQuantLib connects it to the R environment and language.
This version does three new things. First, we fixed an oversight on our end and now allow a null calendar (as the C++ API). Second, the package switched to tinytest as a few of my other packages have done, allowing for very flexible testing during development and deployment—three cheers for easily testing installed packages too. Third, and per a kind nag from Kurt Hornik I updated a few calls which the current QuantLib 1.17 marks as deprecated. That lead to a compile issue with 1.16 so the change is conditional in one part.

Top Skills In Demand For 2020 [Ed: One cannot properly study jobs in need based only on ads in a site owned and controlled by Microsoft]
The start of the year, when it is traditional to come up with self-improving resolutions, is a good time to contemplate new job opportunities. So what are employers looking for in 2020? Here we have two lists of the most sought skills.
The first thing to note is that both of them are biased and there is little common ground between them. The divergence is because they have been constructed with differing goals. As a jobs site Dice is on the look out for the terms that crop up in job postings while LinkedIn Learning is hoping to sign you (or your employer) up to its skill building courses which are provided by Lynda.com, the online learning platform which LinkedIn acquired in 2015.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe 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. |
