Does Gentoo make sense?

Filed under
Gentoo

When I mention to colleagues in the IT industry that compiling packages before installing them on a computer is a good thing, they either give me a blank look or an ever slight smirk. What is the point wasting many hours waiting for some package to compile instead of fetching the binaries from a repository and have it installed in seconds?

Come to think of it, I am actually writing this while waiting for Gentoo to upgrade GCC from 3.4.4 to 4.3.1. It may not sound much but it's actually a big deal. GCC is probably the package that takes the longest slowest to build, in order order of two hours, even on recent dual-core 64bit machines.

Clearly, building from sources is much slower than fetching the binary package. But, building from sources will implicitly check that the required dependencies for the package under construction are available.

KDE: Simple by Default, Powerful When Needed

KDE (back when it was still the name of the desktop environment) and our applications historically stood for powerful features and great flexibility and customizeability. This is what our users love about our software, this is why they choose Plasma and KDE software instead of one of the other Free desktop offerings. And it is also something they would fight tooth and nail for if we wanted to take it away (as many a KDE maintainer who dared to remove a feature he thought was unnecessary can tell). Read more

BitTorrent Bleep alpha released for Android

As an alpha it still has some issues “As with any Alpha, there are some known issues and bugs to work out. Android users will need to set the app to “Wi-Fi Only” unless you have an unlimited data plan; this is only for the time being while we iron out and issue related to battery and data-plan. And while you can move a username from desktop to mobile, Bleep does not yet support moving an existing account from Android to the desktop. And while you can receive messages on multiple devices; messages sent will not be seen across all devices. As with our previous release, communications happen only when all parties are online – you cannot send offline photos or group chats asynchronously.” Read more
