It always seemed to me that you should only need to assign one or the other. If you have a deadline, then what does the priority affect? If the item is high enough priority, isn’t the due date ASAP?

Today, though, I had a flash of insight. The due date defines how much I have to work on the item in order to get it done in time, almost like the velocity of the task. The priority, however, defines how resistant the job is to being derailed by other tasks, more like the inertia or mass of the task.

Put that way, the two values aren’t redundant at all. In fact, you can put them together to determine the overall momentum of a project, based on the combination of the deadline-driven velocity and the priority-based mass. It might even be possible to come up with a formula for determining the outcome of a collision between two tasks, but I’ll leave that as an exercise for the project manager.

The Climate Friendly Cities is a project of the Green Renewable Independent Power Producers (GRIPP), a local non-government organization. In the Ecopolis episode, GRIPP Chairperson Athena Ballesteros explained that she envisioned GRIPP to address the pollution and noise problems that come with the 250,000 or so diesel-fed jeepneys clogging Philippine streets.

The project’s first component involves the use of electric-powered jeepneys – or eJeepneys. Their diesel engines cause traditional jeepneys to emit a lot of noise and smoke. In contrast, eJeepneys run on electric motors and emit barely any noise and no smoke at all. The project’s second component involves the installation of bio-digesters coupled to gas engines – essentially power plants that would convert organic trash to energy, producing electricity to run homes, offices, and, of course, the eJeepneys. The project’s third major component is a piece of land that will serve as the garage, maintenance area and charging station of the eJeepneys.

Radcliffs, get your rockets ready!

Hyperactive Bob, the kitchen production management computer system from Hyperactive Technologies, is now being licensed to Zaxby’s, a fast-food restaurant chain with locations in the Southern states. … This artificially intelligent computer system not only takes orders, it gives them as well.

Hyperactive Bob is frighteningly close to Manna, a science-fictional system proposed by Marshall Brain in his novella-length story of the same name. In the story, Manna is a PC-based system that makes use of sensors around the restaurant to gain information; it then instructs employees. … Hopefully, no one will tell the makers of Hyperactive Bob about the Manna story; it has too many practical suggestions for the enslavement of humans.

This isn’t really a surprise to anyone that’s seen how much fast food restaurants have come to resemble factories. However, it’s good to note how interested corporate chains are in reducing the role of pesky, unpredictable humans.

My take on this is that the gas-price tipping point has finally been reached, so it’s a great time for cities to propose transit alternatives (read: trolleys) and actually get them funded. If I ran a city, I’d make all existing transit free for the next 6 months to get ridership numbers up, then use that period to convince people that transit is worthwhile (or at least figure out why they think it isn’t) while drumming up new funds to make it even better. Of course I don’t run a city, but I hope that folks who do start to see that transit is going to get really important Real Soon Now.
