Today I was looking around for a bug in autoconf, and I noticed one interesting bit out of the NEWS file of the current git version:

Present But Cannot Be Compiled: Autoconf will now proceed with the compiler’s result if a header is present but cannot be compiled. The warning is still printed, and you should really fix it by providing a fourth parameter to AC_CHECK_HEADER/AC_CHECK_HEADERS.

This is a tremendously useful thing to know before autoconf 2.64 is released, which is hopefully not too soon. The reason for this is that finally, after years of having that as a warning, to the point that some projects even ignored it altogether, the new autoconf will start ignoring header files that cannot be compiled, for whatever reason. This is useful since it ensures that headers are not detected that lacks proper dependencies. Unfortunately this also means that any software that currently relies on header files found without compilation will change behaviour.

Peppermint 7 Released

Peppermint 7 launched a few days ago. Peppermint is a lightweight Ubuntu-based Linux distribution with an emphasis on speed and simplicity. Although the name is similar to Linux Mint, the projects aren't directly related. Peppermint originally was envisioned as a "spicier" alternative to Mint—whatever that means! Many distros come with a wide assortment of feature-rich applications, and that's great for power users who need those apps. But older machines can struggle to cope with those demanding distros. Peppermint solves the problem by offering a carefully curated suite of web apps that perform tasks traditionally handled by native apps. It's an approach that will be familiar to any Chromebook users reading this article. Read more
