Why I Target OS X 10.6.8

OS X has come a long way since OS X 10.6.8; among the pluses: better multiple monitor handling, considerably improved memory management (part of which was fixing the leaks in the color management pipeline that OS X 10.6.8 exhibits) repairs to the bugs in 10.6.8′s CUPS printing system, and so on.

So why, then, target OS X 10.6.8?

Headless Raspberry Pi B+ via Ethernet – from zero to success

R.Pi B+ BoadSo (somewhat late to the party, but anyway), I came up with a project I could use a Raspberry Pi for. Off to Amazon I went, and purchased this starter package (select the ULTIMATE kit), which I highly recommend. Everything you need, all in one place. I’m assuming you either bought this kit, or have the things you need, which I will also call out in case you’re a masochist and plan to try to assemble all this stuff by yourself.

Take note that I’ll be updating this post as I discover more stuff about the Raspberry Pi I think is worth sharing; so you might want to bookmark it and come back again from time to time. I’ll try and make it worth your while.

To start, you will require the Pi B+, a storage card with NOOBS on it, a power supply, a wired USB keyboard, a wired USB mouse, an ethernet cable, a free port on your network router or network switch, an HDMI cable and an HDMI capable monitor.

No, there’s no other way. You need the monitor, keyboard and mouse. Sorry. Not my fault. Everything I listed except the network cable, keyboard, monitor and mouse is supplied in the kit I linked to just above. As well as a lot of other really cool stuff. Hint. Hint.

New OSX and Windows version of SdrDx – 2.07

SdrDx 2.07 is an update that introduces external control and communications. First up we have UDP (networked) remote control and monitoring. This allows external applications anywhere on your local network (LAN) to very easily synch up with SdrDx and control it, monitor it, or both. So far, we have two examples (both of which added support in just a few hours.)

The first is DX Toolbox, which will show a list of shortwave stations currently transmitting on the frequency you’re listening to, a great assist with SW dxing, as well as providing a host of propagation graphs, condition and status monitors.

The second is RumLog, which in addition to its powerful and now integrated one-button logging functions, now also serves as a co-ordinating point for keeping SdrDx and a ham transceiver identically tuned and in the same demodulator mode — they track each other live.

Two sample Python scripts, just a few lines each, are also provided to show exactly how to connect to SdrDx via UDP for your own custom applications. It’s so easy to do — just a few simple lines of Python, and you can code up alarm clocks, timed custom recording sessions, and more. Maybe it’s time to learn Python! (Or perl… or any one of many other programming languages. I just recommend Python because it is easy to learn, easy to use, and quite powerful.)

Considerable additional control is available in the UDP interface: I can assist anyone adding this kind of support via external applications.

Next is MIDI control surface support. I’ve chosen the BCR2000 control surface as the default surface. It offers 28 programmable pushbuttons and 32 programmable knobs and is very inexpensive. Also cool looking, festooned with LEDs indicating the current settings in SdrDx. These controls are set up with convenient defaults, but you can easily reprogram any item with just a couple of mouse clicks or keypresses. Running SdrDx with real knobs and buttons is downright *fun*. :)

There are some other goodies in 2.07 as well, but those are definitely the stars. Enjoy!
