The Spectre And Meltdown Server Tax Bill

  • The Spectre And Meltdown Server Tax Bill

    Much has been written about the nature of the Meltdown and Spectre threats, which leverage the speculative execution features of modern processors to give user-level applications access to operating system kernel memory. This is obviously a very big problem. Chip suppliers and operating system and hypervisor makers have known about these exploits since last June, and have been working behind the scenes to provide corrective countermeasures to block them. The idea was to wait until January 9 to have all the fixes lined up in the industry and then tell the world about the exploits. But rumors about the speculative execution threats forced the hands of the industry, and last week Google put out a notice about the bugs and then followed up with details about how it has fixed them in its own code for its own systems.

GNOME: libxmlb, Glade Support for Builder and Vala

  • libxmlb now a dependency of fwupd and gnome-software
    I’ve just released libxmlb 0.1.3, and merged the branches for fwupd and gnome-software so that it becomes a hard dependency on both projects. A few people have reviewed the libxmlb code, and Mario, Kalev and Robert reviewed the fwupd and gnome-software changes so I’m pretty confident I’ve not broken anything too important — but more testing very welcome.
  • Christian Hergert: Glade Support for Builder
    One of the things we’ve wanted in Builder for a while is a designer. We’ve had various prototypes in the past to see how things would have worked out, and mostly just punted on the idea because it seemed like Glade served users better than we would be able to directly. Last week, Juan Pablo, Matthias Clasen and I met up in San Francisco to see what we could do in the short term. We discussed a couple of options that we have going forward. Integrate glade 3 into Builder using libgladeui. Integrate glade 3 using the external Glade application and use D-Bus to inter-operate. Like all projects, we have some constraints.
  • Daniel Espinosa: Vala state: October 2018
    While I think maintainability could be improved, adding to history commits from contributions, apart from the ones coming from current Maintainer. Actually, there are some lot of commits not in history coming from authors outside current ones. Hope with new GitLab GNOME’s instance, this will reflect the correct situation. Behind scenes, Vala has to improve its code base to adapt to new requirements like to develop a descent Vala Language Server and more IEDs supporting Vala. At least for me, even GEdit is productive enough to produce software in Vala, because the language itself; write a Class, an Interface and implement interfaces, is 10 times faster in Vala than in C. Vala has received lot of improvements in last development cycles, like a new POSIX profile, ABI stability, C Warnings improvements and many other, to be reported in a different article. Look at Vala’s repository history, you will see more “feature” commits than “bindings” ones, contrary to the situation reported by Emmanuel, while should be a good idea to produce a graphic on this, but resent improvements could tell by them self the situation has been improved in recent release cycles. Lets look at repository’s chart. It reports 2000 commits in the last 3 months, 1.1 average per day, from 101 contributions as for October 19, 2018. Me at 10 commits from the last year, so I’m far to be a core contributor, but push ABI stability to be a reality. My main contributions are to communicate Vala advances and status.

  • Birdtray: Thunderbird Tray Icon With New Email Notifications For Linux (Firetray Alternative)
    Birdtray adds a system tray icon for Thunderbird email client on Linux (Xorg), which shows the unread email count. Besides this, Birdtray supports snoozing new email notifications, configure for which accounts / email folders to notify of new emails, and more. FireTray and other solutions to add a tray icon for Thunderbird that displays an unread email count stopped working with Thunderbird 60. Birdtray checks the unread email status directly by reading the Thunderbird email search database, which makes it immune to Thunderbird API changes. As a result, Birdtray is a great Firetray alternative that shouldn't break on Thunderbird updates.

Open Source 3D Printing and Open Source MIDI Foot Controller

  • Open Source 3D Printing: Exploring Scientific and Medical Solutions
    3D Printing is not a new thing to hear about. It is a very popular industry right now that began in the early 80s. But how different is Open Source 3D Printing from proprietary designs? How does this affect its applications in Science and Medicine? Let’s read on.
  • Finally, An Open Source MIDI Foot Controller
    MIDI has been around for longer than most of the readers of Hackaday, and you can get off my lawn. In spite of this, MIDI is still commonly used in nearly every single aspect of musical performance, and there are a host of tools and applications to give MIDI control to a live performance. That said, if you want a MIDI foot controller, your best bet is probably something used from the late 90s, although Behringer makes an acceptable foot controller that doesn’t have a whole bunch of features. There is obviously a need for a feature packed, Open Source MIDI foot controller. That’s where the Pedalino comes in. It’s a winner of the Musical Instrument Challenge in this year’s Hackaday Prize, and if you want a MIDI foot controller, this is the first place you should look.
