Dirk Eddelbuettel: RcppAPT 0.0.9: Minor Update
A new version of the RcppAPT package with the R interface to the C++ library behind the awesome apt, apt-get, apt-cache, … commands and their cache powering Debian, Ubuntu and the like arrived on CRAN earlier today.
RcppAPT allows you to query the (Debian or Ubuntu) package dependency graph at will, with build-dependencies (if you have deb-src entries), reverse dependencies, and all other goodies. See the vignette and examples for illustrations.

What's In That String?
One of the steps of debugging Perl can be to find out what is actually in a string. There are a number of more-or-less informative ways to do this, and I thought I would compare them.
For this I used two short strings. The first was just the concatenation of the characters whose ordinals are 24 through 39; that is, 16 ASCII characters straddling the divide between control characters and printable characters. The second was a small variation on the first, made by removing the last character and appending "\N{U+100}" (a.k.a. "\N{LATIN CAPITAL A WITH MACRON}") to force the string's internal representation to be upgraded.
The results given below include the version of the module used, the actual code snippet that generated the output, the output itself, and any comments I thought relevant. All subroutines used to dump strings are exportable except for those called as methods. The sample code makes fully-qualified calls because of duplication of subroutine names between different modules.

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. |
