Chasing a stubborn problem with CC2500 radios last night. Eventually it turned out to be a problem with compiler settings for the cross-compiler generating code for a slightly different platform. Because of the similarities the firmware image didn't fail outright and made the mistake that much harder to detect.

The series of our Jaw crusher include 11 models which can meet most capacity requirements in primary and secondary crushing, at the same time, with low power consumption and easy maintenance. Every feature of these machines has been carefully designed to provide superior quality and performance. The high capacity of this pulverizer machine can be ensured by the large feed opening and force-feeding action from the inward and downward eccentric movement of the swing jaw.
The jaw crusher has a smaller discharge setting, allowing for a higher degree of flexibility with relative equipment. The machine is easy to install and debug. They are widely applied in areas of mining, metallurgical, construction, smelting, hydraulic and chemical industries, etc and widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc. These crushers are recommended by leading consultants in this field and are used by hundreds of customers all over the world.
It would be impossible for me to overstate how frustrating today was. Effectively I spent 9 hours debugging a problem that was (as far as I can tell) completely non-deterministic / irrational. I swapped out everything, software and hardware. I reset everything. I jiggled the thingy. I rebooted stuff. I rebuilt. And then, just as magically as the crash had shown up, at about 5pm it just disappeared. The most horrifying thing is that for every thing that I did in the 30 minutes leading up to "it works", I can pretty decisively argue that thing as being NOT involved in the problem.
There are days that really make me question how cold and rational computers really are. If I was just slightly more superstitious, I would point at today and say, "There was a demon sitting on my desk today."
This is take-out dessert from the local bakery. In shooting this, I decided to consciously try the opposite approach that I would ordinarily use. So instead of starting with a wide-open lens, I'd shoot as narrow as possible (this is f/36), and instead of bringing out a big diffuser like my favorite umbrella, I'd shoot with two bare bulbs and see if I could tame the light with reflectors and in post. I'm not wholly convinced it worked, but it was at least fun to try.
Victoria is flying out to visit her folks for a few days starting tomorrow. So even if long hours continue, I'll start being a proper flickr friend again tomorrow night.
The Z8-02 bondout is connected to a 28C16 EEPROM serving as the emulated ROM. (Typically a 2716 EPROM would have been used.) The 28C16 has been programmed with a copy of the masked ROM from the Z8671 Single Chip Interpreter BASIC/Debug. An async serial to USB adapter is connected to a laptop running Kermit.
A simple but inefficient BASIC program to find prime numbers has been entered, and the LIST command used to list it back out for verification. The program is RUN, then stopped after a few prime numbers have been found.
It's true, errors are the prettiest part of graphics programming.
This pretty garbage haunted my late nights for a while as I finished my (free) Photoshop PSD Extract/Recovery plugin, telegraphics.com.au/sw#psdrecover
Front view of an Innsbruck box, with the faceplate screwed into place. The left two BNC columns are the 8 feedback inputs. The middle BNC columns are TTL digital outputs (not all of them are connected). The SMA columns allow us to disconnect and debug the eval boards from the outside: VGA RF input and output, VGA gain input, DAC output, DDS output, and 1 GHz clock input from the Marconi synthesizer sitting underneath.
