  • Raspberry Pi 3 and alternatives

    Wow what a great day for low cost processors. The conversion to 64 bit is on and that means much simpler software development. We are moving away from the strange hybrid architecture of the original Raspberry Pi (ARMv6 with hardware floating point) to 64-bit and fast GPUs. Also the busses are getting better so some…

  • Mac Ethernet didn't work for a day…

    OK more than a day, but there was a bad update where Apple accidentally blacklisted their own driver (ugh, I’m sure someone is getting yelled at right now). It should be fixed automatically if you are using the automatic update feature. Mine was broken at on Friday and fixed Saturday at 530PM, so software update…

  • Servers in 2016

  • Drooling for a gpu farm 

    Never had so much fun learning about a new topic or building a computer but at last I have a reason to want a $5k desktop! arriving in two days! Of course since then it’s pretty clear that instead of the i7 we should Xeon e5-1650 v3. It’s the same chip and costs the same…

  • Haven't been posting much

    Most of notes now go to slack. It’s so convenient to post there as I do most things in my phablet these days.

    Wow this is a cool application. it uses a web browser on the Mac and then you use a QR code to connect it to an Android device. This gives the local IP address of the Mac to the phone and somehow the browser application can facilitate the transfer
