NewSQL – RDBMS on Steroids
No this is not a misprint. Yes we mean NewSQL, not NoSQL. Recently a colleague asked me about NewSQL and I had to admit that I hadn’t kept up. While it initially had a lot of press, much less so now. Was it still relevant? And if so under what circumstances should you consider it?

HTTPS for CRAN: how and why
R gained some basic support for https in version 3.2.0 via the method = ‘libcurl’ argument in base functions download.file and url. The global option download.file.method is used to make this the default. Unfortunately the implementation has a few limitations: there is no way to set request options (authentication, proxy, headers, TLS options, etc) and the functions do not expose an http status code or response headers. Because they also do not raise an error when the request fails with an http error (as do the other download methods), this leaves you to guess if the retrieved content is what you were expecting or an error page.
