02:22 AM Ruby Feature #12871: Using the algorithm like math.fsum of Python for Array#sum

Thank you.
Julia's algorithm looks good. But in some case, Python's algorithm is still better than that.

# julia 0.5.0
sum_kbn([1.0e100, 1.0, 1.0e-100, -1.0, -1.0e100]) # => 0.0

04:46 AM Ruby Feature #12871 (Closed): Using the algorithm like math.fsum of Python for Array#sum

Array#sum uses the Kahan's algorithm for Float values now. But it returns inaccurate value in some case like below.
~~~ ruby
# ruby 2.4.0-preview2
[10000000000.0, 0.0000000001, -10000000000.0].sum #=> 0.0 (expected 0.0000000001)

`WEBrick::HTTPProxy#do_CONNECT` closes connection when `Errno::EAGAIN` or `Errno::WOULDBLOCK` occurred.
These exceptions will raise when the socket is not writable temporally.
I expect that the proxy will wait until the socket will be ... labocho (Keisuke NISHI)
