  • Team OpenCensus or OpenTracing? It'll be neither and both now: Hello, OpenTelemetry
    Something odd happened at KubeCon 2019. Rather than snipe at each other from the safety of Twitter, two very similar open-source projects opted to pool their ideas into one: OpenTelemetry. The project is geared towards solving the problem of working out just what the heck is happening in today's microservices or container-based apps. Logging without incurring a chunky overhead both in terms of generating useful telemetry and actually collating the output. Distributed tracing is a bit more than fancy logging, as one commentator put it. Think more a transaction log over all the containers, services and components used in an application. Two projects emerged to deal with the challenge – OpenCensus from Google and OpenTracing, co-created by Ben Sigelman of Lightstep.
  • PHP 7.4 as Software Collection.
    Version 7.4.0-alpha1 will be soon released. It's now enter the stabilization phase for the developers, and the test phase for the users. RPM of this upcoming version of PHP 7.4, are available in remi repository for Fedora 29, 30 and Enterprise Linux 7, 8 (RHEL, CentOS, ...) in a fresh new Software Collection (php74) allowing its installation beside the system version. As I strongly believe in SCL potential to provide a simple way to allow installation of various versions simultaneously, and as I think it is useful to offer this feature to allow developers to test their applications, to allow sysadmin to prepare a migration or simply to use this version for some specific application, I decide to create this new SCL.

Drill: New Desktop File Search Utility That Uses Clever Crawling Instead Of Indexing

Drill is a new file search utility that uses "clever crawling" instead of indexing, for Linux, Windows and macOS. The application can locate files and folders, but it does not search file contents. It's designed for desktops, using a Gtk GUI by default, but there's also a command line frontend available, albeit quite minimal right now (a Ncurses backend is on the todo list as well). Read more
