Is the ASRock Q1900DC-ITX Intel Motherboard a Good ARM SBC Alternative?
In the recent series on ARM single board computers I have covered the BeagleBone Black, MaRS, TI's OMAP5432 Board, the Radxa, a few of the ODroid ARM machines, and many more. On the Intel desktop side I've covered the NUC and MinnowBoard. I've learned that outright performance is faster on the Intel NUC than any ARM machine reviewed so far -- the tradeoff, of course, is cost. This time around we'll see whether the ASRock Q1900DC-ITX motherboard retains the high performance characteristic of an Intel board but also dips down to the low cost and lower power draw of the ARM world.
Apple OS X 10.10 vs. Ubuntu 14.10 Performance
While I delivered some OS X 10.10 Yosemite preview benchmarks back in August, here's my first tests of the official release of Apple OS X 10.10.1 compared to Ubuntu 14.10 Linux. Tests were done of OS X 10.9.5 and OS X 10.10.1 against Ubuntu 14.10 Utopic Unicorn when running the benchmarks under both GCC and LLVM Clang compilers.
Fedora 21 review
It's been a while since my last upgrade and there has also been a gap to the latest Fedora 21 release, so now seemed like a good time. I upgraded my laptop by installing over the existing root partition but leaving the /home partition in place to maintain all my settings and files. I wasn't able to even attempt this in the Fedora 16 installer, but it was easy enough in the Fedora 21 installer and it worked surprisingly well. Downtime was only 20 minutes or so for the installation, though a couple of hours was needed to investigate various new settings etc.
