I did a little preliminary research today on how to measure postgres performance, including on AWS.
Postgres can be configured to log query-related data.
These logs can be exported to tools like pgbadger or hosted tools like pganalyze. Datadog seems to have some options, too.

| // TODO: seems to be per-window. how to iterate and attach to all windows? :-( | |
| menu = document.getElementById("contentAreaContextMenu"); | |
| // create a hidden menu item | |
| xuldoc = menu.ownerDocument; | |
| item = xuldoc.createElement('menuitem'); | |
| item.setAttribute('id', 'minvid-item'); |
I've seen this error so many times when I first open the Firefox Browser toolbox:
Error opening Browser Toolbox:
Component returned failure code: 0x804b000d (NS_ERROR_CONNECTION_REFUSED) [nsIInputStream.available]
The fix is almost always to close and reopen the toolbox, and it'll connect just fine.
I'm helping to land a Test Pilot experiment (Page Shot, now dubbed Firefox Screenshots) in Firefox.
We're landing it as a system addon~, preffed off, but it still has some unknown impact on memory consumption and startup performance.
This will be my first time profiling anything in Gecko, and it seems like it might be worth writing down my steps, both for others wanting to try it out, and to identify rough spots in the APIs or missing bits of documentation.
Steps:
I keep forgetting this and relearning how to do it.
go to bug 1346825
find the build system commit (currently attachment 8855871)
just apply the raw diff locally to the various files (for whatever reason, I often find patch barfs on the diff)
The direct number to USPS customer service is: 678-279-7980.
Be prepared for a 30-60 minute wait, but you will actually speak to a person.
I spent hours digging through amazon/ebay/etc seller forums, and eventually uncovered the phone number above. When I called, I waited about an hour to speak to someone, then the person at the other end added a comment to my lost package case number, asking the person assigned to the case to actually work on it, and my

I need to click a link to trigger an install of 1.0.12, to verify that it will upgrade to 1.0.13 and self-uninstall:
