Dear Google Mail Team,

  I've said very nice things about your spam filter in the past, but I'm afraid I am going to have to take it all back. I'm currently going through the spam for the last week, and have gone through about a third of it.

Something you did recently has been an unmitigated disaster. Of the roughly 1000 spam threads I've gone through so far, right now 228 threads were incorrectly marked as spam.

That's not the 0.1% false positive rate you tried to make such a big deal about last week. No. That's over 20% of my spambox being real emails with patches and pull requests.  Almost a quarter!

I don't know how to even describe the level of brokenness in those kinds of spam numbers. There were a few pages of email (I've got it set up so it shows me 50 threads per page) where more than half of the "spam" wasn't.

Quite frankly, that sucks. It's not acceptable. Whatever you started doing a few days ago is completely and utterly broken.

It's actually at the point where I'm noticing missing messages in the email conversations I see, because gmail has been marking emails in the middle of the conversation as spam. Things that people replied to and that contained patches and problem descriptions.

They didn't try to sell me a bigger penis or tell me about how somebody is cheating on me. Really.

You dun goofed. Badly. Get your shit together, because a 20% error rate for spam detection is making your spam filter useless.

[ Edit: looks like it started four days ago. As of July 13, it looks like a big swath of lkml has been marked as spam for me. ]

[ Edit 2: final numbers: out of around 3000 spam threads, I had to mark 1190 threads as "not spam". So the numbers actually got worse: about 30% of my spam-box wasn't actually spam. It started around 1pm on Monday, July 13th. The problem really is that clear, that I can tell pretty much when it started ]

[ Edit 3: it wasn't just patches, and it's not just lkml. There were things like Junio's recent git v2.5.0-rc2 announcement etc. The new gmail spam filter hates any mailing list emails, apparently. In the time I wrote the last note, I got seven more emails marked as spam, two of which weren't. ]

A thought on how to add a REPL to an app or service:

Your REPL starts by creating a persistent connection to the app or service.  Could be as simple as a login and a cookie jar, or could be a socket open to the app.  Then the REPL starts a bash subshell.  In that process there are new commands for all the different things the application supports.  You get a full language and a sort of scriptability, but you don't have to implement anything beyond exposing commands.

I realize in some sense the subshell is just a way-too-fancy context manager or try/finally for bash.  But the idea of starting a shell session seems vague in bash.  And it's the session that makes the script hang together as a command language.

Freezing LEDs in liquid nitrogen causes color change

When cooled in liquid nitrogen at -196°C, the band gap of the LED semiconductor increases. This causes an increase in the energy of the emitted photons and therefore a decrease in emission wavelength. When the yellow LED (λ = 570nm) is submerged it shifts towards emitting a green color (λ = 510nm). When the red LED (λ = 650nm) is submerged it emits a more orange color (λ = 590nm).

Nice illustration of the summer solstice
 
Happy Summer Solstice!
Today is the first day of summer. Summer officially began 12:38 pm EDT.

Astronomy has been important to people for thousands of years. The ancient construction known as Stonehenge in England may have been designed, among other purposes, to pay special honor to the solstices and equinoxes. These are the times and locations during Earth's journey around the Sun that ...
