BSD: FreeBSD, zpool and OpenBSD

Filed under
BSD
  • zpool checkpoints

     

    In March, to FreeBSD landed a very interesting feature called 'zpool checkpoints'. Before we jump straight into the topic, let's take a step back and look at another ZFS feature called ‘snapshot’. Snapshot allows us to create an image of our single file systems. This gives us the option to modify data on the dataset without the fear of losing some data.

  • Reflection on one-year usage of OpenBSD

     

    I have used OpenBSD for more than one year, and it is time to give a summary of the experience...

  • OpenBSD on an iBook G4 [iophk: "it was a sweet machine in its time"]

     

    In summary I was impressed with OpenBSD and its ability to breathe new life into this old Apple Mac. I'm genuinely excited about the idea of trying BSD with other devices on my network such as an old Asus Eee PC 900 netbook and at least one of the many Raspberry Pi devices I use. Whether I go the whole hog and replace Fedora on my main production laptop though remains to be seen!

Single-board computer guide updated: Free software is winning on ARM!

In many geeky circles, single-board computers are popular machines. SBCs come in small form factors and generally run GNU/Linux, but unfortunately, many boards like the popular Raspberry Pi are dependent on proprietary software to use. The Free Software Foundation maintains a list of system-on-chip families, sorted by their freedom status. Unfortunately, this list had not been updated in several years. While it was accurate when it was published, free software is constantly improving. Today, more and more boards are usable with free software. On the graphical side, the Etnaviv project has reached maturity, and the Panfrost project, with which I have been personally involved, has sprung up. The video processing unit on Allwinner chips has been reverse-engineered and liberated by the linux-sunxi community in tandem with Bootlin. Rockchip boards have become viable competitors to their better known counterparts. Even the Raspberry Pi has had a proof-of-concept free firmware replacement developed. Free software is winning on ARM. Read more

Official TV HAT brings DVB-T2 streaming to the Raspberry Pi

The Raspberry Pi Foundation has launched a Raspberry Pi TV HAT with a Sony CXD2880 TV tuner for receiving DVB-T2 transmissions in Europe. The $21.50 board debuts a half-size HAT format. The computer that was born to empower technology education in the UK can now be rejiggered into an old-fashioned idiot box. The Raspberry Pi Foundation has produced an official HAT add-on board for the Raspberry Pi with a Digital Video Broadcast (DVB) tuner that receives terrestrial TV signals. The $21.50 Raspberry Pi TV HAT lets you stream DTV-T2 and DTV-T video in the UK and Europe. Read more
