Chris Baus: TCP_CORK: More than you ever wanted to know
Even with buffered streams the application must be able to instruct the OS to forward all pending data when the stream has been flushed for optimal performance. The application does not know where packet boundaries reside, hence buffer flushes might not align on packet boundaries. TCP_CORK can pack data more effectively, because it has direct access to the TCP/IP layer. [..] If you do use an application buffering and streaming mechanism (as does Apache), I highly recommend applying the TCP_NODELAY socket option which disables Nagle’s algorithm. All calls to write() will then result in immediate transfer of data.

A gut microbe that stops food allergies
Actual scientific research showing that antibiotic use may be implicated in allergies: ‘Nagler’s team first confirmed that mice given antibiotics early in life were far more susceptible to peanut sensitization, a model of human peanut allergy. Then, they introduced a solution containing Clostridia, a common class of bacteria that’s naturally found in the mammalian gut, into the rodents’ mouths and stomachs. The animals’ food allergen sensitization disappeared, the team reports online today in the Proceedings of the National Academy of Sciences. When the scientists instead introduced another common kind of healthy bacteria, called Bacteroides, into similarly allergy-prone mice, they didn’t see the same effect. Studying the rodents more carefully, the researchers determined that Clostridia were having a surprising effect on the mouse gut: Acting through certain immune cells, the bacteria helped keep peanut proteins that can cause allergic reactions out of the bloodstream. “The bacteria are maintaining the integrity of the [intestinal] barrier,” Nagler says.’

#5045 (epoll_reactor::update_timeout() uses incorrect interrupter if TIMERFD is not available) – Boost C++ Libraries
ah, memories. This is the bug that caused me to have to run a fleet-wide upgrade across the EC2 substrate. Thanks, boost::asio!
