How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Redis 4.2 roadmap

Redis Cluster

Speed up key -> hashslot association. Now makes RBB loading 4x slower when there are many small keys.
Better multi data center story
redis-trib C coded and moved into redis-cli
Backup / Restore of Cluster
Non blocking MIGRATE (also consider not using 2X memory)
Faster resharding
Bug fixing and stress testing to bring it to next level of maturity

These links no longer work. Springer have pulled the free plug.

how to destroy/end streams in node >= 0.10

usually you call .destroy() if it has .destroy
if it doesnt have .destroy you are out of luck and the stream should upgrade to use e.g. newer through2
in request you call .abort() (this should get fixed to use .destroy())
.end() tries to end the stream gracefully

what about close

From Fabrice Bellard, with minor name change (umulh):

// return the high 32 bit part of the 64 bit addition of (hi0, lo0) and (hi1, lo1)
Math.iaddh(lo0, hi0, lo1, hi1)

// return the high 32 bit part of the 64 bit subtraction of (hi0, lo0) and (hi1, lo1)
Math.isubh(lo0, hi0, lo1, hi1)

// return the high 32 bit part of the signed 64 bit product of the 32 bit numbers a and b

Data Serialization Formats

JSON, MessagePack, and Google's Protocol Buffers are all awesome. Here's how they're awesome on different client environments and how to use them on your rails env.
