My father's in his mid 70s and his hearing isn't very good in the frequency range that would be useful for finding his vacuum leaks.

I was thinking about setting him up with a directional microphone and a pitch-shifter app to bring environmental sounds down a couple octaves so he can hear them. There are tons of Android/iPhone apps that will pitch-shift in post, but none of the trial/freemium ones seem to work on a realtime monitor stream, especially on an external USB (UAC) microphone. I don't want to start buying dozens of apps just to try them.

Any app suggestions or other ideas for him?

I've got a handful of domains coming up for renewal. Do you know of a low-cost Canadian Registrar that supports scripted/API management so I can keep my dynamic DNS updated?

I know about EasyDNS, but they want an extra $20/yr/domain for dynamic DNS. All the other Canadian registars I've looked at have no API support.

Saw this over on the other site. Seems like a fantastic idea.

It's time for me to re-evaluate my selection of ETFs, and it always drives me crazy looking up their MERs one by one. I really wish it was in the GOOGLEFINANCE sheet function.

Is there any way to programatically get MERs? Like even a publically available spreadsheet with the most common ETFs would be better than nothing.

I've been trying to minimize my US buying. Can't found a way to get my kids off the US broccoli yet, but this site has been useful helping me find Canadian alternatives to a lot of packaged shelf-stable products.

I've seen a lot of made-in-USA products placed on the shelf upside down. That helps, please keep doing it!

My question: which grocery stores in town are doing the best jobs of making it clear which foods are domestic?
