Traffic Question 5:

What do you do when your car falls into a pothole?

If you’ve driven in Moline, you know about the potholes. I think the high school has a special driver’s ed section about pot holes and what to do if you fall into one bigger than your car.

It’s not street driving, and it’s not off-roading... it’s called Moline-roading. Jeep offers a Moline-Roading package that comes standard with heavy duty suspension, lift package, and front and rear winches.

My daughter has her own version of The Wheels on the Bus... “go clunkety-clunk, clunkety-clunk, clunkety-clunk”.

The way the city fixes these is the pebble-pooper: it dumps in some gravel and then squirts in some tar. Theoretically, it hardens up and meshes with the road. It sort of works until next time it rains or snows. A few days after application, anyone driving on it sprays gravel and tar everywhere.

So to answer the quiz question... well, that’s left as an exercise for the student.

Converting version control repositories from Bazaar to Git (bzr to git)

Submitted by drew on

Bazaar is great on Windows. Several years later, git's tools for Windows still.... (ahem) are lacking or too commercial. However, official development on it has ended and git is so much more popular now. So I think the time has come to convert all my beloved bzr repositories to git.

First we need note some prerequisites:

Adding a hardware clock to Raspberry Pi (DS3231)

Submitted by drew on

The popular clock module is uses the DS1307 real time clock chip, which is not very precise. For just a few dollars more, you can get a module with a much more precise DS3231 RTC chip. The one I got was SunFounder's module from Amazon for $9 (free shipping for Prime). It plugs right onto the Raspberry Pi's 40 pin header and doesn't even interfere with the plastic case I have. I have a Model B, but this module should also work on Model A and Model B+. The instructions refer to DS1307, but the chips use the same I2C commands, so it also works for DS3231.

How to run a PiPresents show when you don't have a Raspberry Pi

Submitted by drew on

PiPresents is some pretty cool software that will run a PowerPoint-like presentation. But with lots more flexibility. It was originally written for the Raspberry Pi.

However.... perhaps someone else has your Pi. Perhaps you don't even have one. It is possible to run a PiPresents show on  your good ol' desktop computer (Windows, Linux, or Mac). Here's how.
