The pink is the new and improved entrance to Walmart. What’s wrong with this picture?

  1. Nothing, this is the best design possible.
  2. Oh, man! How am I going to hold on to my phone around all those curves?
  3. It needs to wrap around the car dealership more, maybe even a full loop
  4. Everything

City of Moline's Answer:

Well, since this is what they are implementing, I gues it’s the best they can come up with....

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.

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.
