I finally got a full harvest off of this vine (before birds, etc.) These grapes are pretty sour, if you just pick and eat. And seedy. However, I always thought they might make good jelly or something. So this year, I have lots of grapes to try something.

Basically, the process is:

  1. Pick grapes. Wash under running water and remove bad stuff.
  2. Get one of these and mash/juice: Oxo Food Mill. That's the one we got, anyway. I would say it's ok (better than a potato masher), but not great. I was looking at this Victorio  because it looks like it would be better for decent volume, but other people were turned off by the plastic parts.
  3. Run juice through fine mesh sieve, such as cheesecloth (the closest thing I had handy was a bedsheet).
  4. Follow instructions on the package of pectin to fill jars. I only had 6 cups sugar handy instead of the 7 that the package calls for, so we'll see how it turns out. The instructions say not to reduce the sugar or the jelly will fail to set, but it looks like it's setting to me. The funnel for those jars was super handy and I would recommend it versus a makeshift one.
  5. After filling jars, enjoy stuff left over in pan on toast.

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

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)

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

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.
