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.

  • 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.
