Moliner’s Answer:

A or B, it doesn’t matter.

It really depends on the situation.

  • Example 1: if you’re on the phone, you can’t really be expected to use both hands on the wheel to make such a sharp turn. Or to slow down for it. The other driver will stop and wait for you; no worries. Go ahead and use both lanes.
  • Example 2: There may be something blocking the view of the side street. If you can’t see around the turn, feel free to drive like there’s no other car. If you can’t see them, it means they aren’t there. Go ahead and use both lanes.

Conventional Answer:

B. You should always stay in your own lane.

You can’t count on another driver to do any particular thing. Or to even be paying attention.

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.
