• Deploy != Release

  This turned out to be somewhat controversial until we discussed what I specifically meant by deploy and release.

  As with all things, agreeing on definitions or understanding what someone means when they use a specific term is essential, so I thought I would write down a short blog post on it.

• Dirk Eddelbuettel: tint 0.1.4 on CRAN: Miscellaneous Updates

  A new version 0.1.4 of the tint package arrived at CRAN today. tint provides a style ‘not unlike Tufte’ for use in html and pdf documents created from markdown. The github repo shows several examples in its README, more as usual in the package documentation.

  This is the first release in over two years and it brings a few incremental changes which are described in detail below. The trigger was an email from CRAN desiring compacted pdf files inside the package sources. Which, coincidentally, was made a default about a year ago in the build.r script from littler I use to make packages. But as we had not updated tint this has not reached CRAN. So there.

• Dirk Eddelbuettel: RcppXts 0.0.5 on CRAN: Maintenance

  A new maintenance release 0.0.6 of RcppXts is now on CRAN. The RcppXts package demonstrates how to access the export C API of xts which we contributed a looong time ago.

• Paul Tagliamonte: Decoding LDPC: k-Bit Brute Forcing

  I've been working on the next generation of the "PACKRAT" series called "RATPACK". I'm hoping to start writing new posts soon, and hopefully this is an interesting note of what's to come! In the meantime, you can check out the PACKRAT posts until then. My initial efforts to build a PHY and Data Link layer – from scratch using my own code – have been progressing nicely since the initial BPSK based protocol I’ve documented under the PACKRAT series. As part of that, I’ve been diving deep into FEC, and in particular, LDPC.

  I won’t be able to do an overview of LDPC justice in this post – with any luck that’ll come in a later post to come as part of the RATPACK series, so some knowledge is assumed. As such this post is less useful for those looking to learn about LDPC, and a bit more targeted to those who enjoy talking and thinking about FEC.

• Ubuntu Summit 2022

  I’ll share a lot of examples from my personal participation in the the Python and Django community.
