in reply to Measuring programmer quality

When Labour came to power in the UK they introduced many tests and targets for all levels of government to improve standards. Staff were "empowered" to do anything they wanted to meet the targets and as the targets were correlated with good service what could go wrong?

One police force reclassified most minor crimes as disturbances giving them a massive reduction in reported crime. Hospitals reclassified corridors as "transit wards" and took the wheels of trollies declaring them as beds - now there are no patients waiting on trollies in corridors...!

Even with the best intentions and mostly decent people, if there is pressure to conform to arbitrary standards people conform to the standard even if it's no benefit to the end user in any way. While some people feel very smug, the whole targets process has been a vast waste of money and probably done more harm than good.

Having just gone through a Lean Six Sigma training course, it is vital that you measure the things that the end user actually cares about, not things that may just correlate with them. However, it is really, really hard to come up with good targets and tests and if you get them wrong you will do a lot of harm as the UK government has...

[stevieb]: well, what happens is the Arduino 'listens' for requests r/w, and does the appropriate thing when it's interrupted based on the 'register' address sent in. It's ugly as it was my first attempt, but I've got great new ideas I'm just sitting.
[stevieb]: ...down to implement now. Here's the sketch as it currently sits
[shmem]: well I use I2C and SPI and stuff, but creating a pseudo chip looks to me like lot of indirection and memory clutter... not?
[choroba]: Are you going to use the device soon? Related to your comment about "not having much time to do a lot of coding"...
[stevieb]: sure, but I'm just learning ;) I consider it practice to get a good understanding of what goes on *after* an I2C/SPI request is made
[shmem]: ah ok. Gonna read that. but now....
shmem compiles himself into his template
[stevieb]: this is my RPi:: distribution overall automation build system physical layout. It doesn't encompass all of my RPi dists yet, ...
[stevieb]: ...but I'm getting close. I've been soldering my own PCBs to gain that experience as well, before I have my own manufactured.
[stevieb]: heh, nice *template* ;) 'night shmem!
