  • Not every bit of code you write needs to be optimal

    It's easy to fall into the trap of obsessing about performance and try to micro-optimize every little detail in the code you're writing. Or reviewing for that matter. Most of the time, this just adds complexity and is a waste of effort.

    If a piece of code only runs a few (or even a few hundred) times a second, a few nanoseconds per invocation won't make a significant difference. Chances are the performance wins you'll gain by micro optimizing such code won't show up on a profile.

  • Making tab switching faster in Firefox with tab warming

    Since working on the Electrolysis team (and having transitioned to working on various performance initiatives), I’ve been working on making tab operations feel faster in Firefox. For example, I wrote a few months back about a technique we used to make tab closing faster.

    Today, I’m writing to talk about how we’re trying to make tab switching feel faster in some cases.

Livepatching With Linux 5.1 To Support Atomic Replace & Cumulative Patches

With the Linux 5.1 kernel cycle that should get underway in just over one month's time, there will now be the long in development work (it's been through 15+ rounds of public code review!) for supporting atomic replace and cumulative patches. Read more

GNOME/Xfce/GTK: Exo 0.12.4 and Libhandy 0.0.7 Released

  • Exo 0.12.4 Released
    Exo 0.12.4 is now available with an improved icon view, better icon rendering, and reduced disk usage.
  • My Name is Handy, Lib Handy
    Libhandy 0.0.7 just got released! [...] A common pattern in GNOME applications is lists, which are typically implemented via GtkListBox. More specific patterns arose, where rows have a title at the start, an optional subtitle below it, actions at the end and an icon or some other widget like a radio button as a prefix. These rows can also be expanded to reveal nested rows or anything else that fits the need. So far every application using these patterns implemented the rows by hand for each and every row. It made using these a bit cumbersome and it led to inconsistencies in sizing, even inside a single application. To make these patterns easier to use, we implemented HdyActionRow, HdyComboRow and HdyExpanderRow.

How did you get started with Linux?

The Linux mascot is a penguin named Tux, so we thought it appropriate to celebrate Penguin Awareness Day for the conservation of penguin habitats and talk a little bit (more) about Linux. A few fun penguin facts: These furry creatures are flightless yet part of the bird family. Some are large, like the Emperor penguin, and some are small, like those found in New Zealand. And, the Gentoo penguin is known to swim up to a speed of 21 miles per hour! Now, for the Linux bit. I asked our writer community to describe the moment they learned about Linux or the moment they got it up on running on their machine. Here's what they shared. Read more
