Big In Akkad Edition

Tech News

  • I mentioned yesterday that Python has a library for everything.

    Need to systematise your noun declensions in Classical Akkadian?  There's a library for that.

  • Crystal, as I mentioned, is single-threaded and has no serious inter-process IPC.  If you are building a server application that needs to scale beyond one CPU core that's a problem, unless you are talking over a socket as pretty much every server application does, and are running on Linux kernel 3.9 or later, as pretty much every server does.  In that case:

    • reuse_port to enable multiple processes to bind to the same port (SO_REUSEPORT).

    You can just set the socket and start up multiple independent processes, as many as you like, all listening on the same port number.  And basically that's it.  Client connections go to whichever process grabs them first.  It just works.

    Not on Unix sockets though.  Which means it is merely incredibly useful rather than perfect.  I wondered how the Amber web framework got its performance numbers - whether it was tested behind a load balancer of some kind.  No.  Or to put it another way, yes, but the load balancer is inside the Linux kernel.

  • Speaking of Linux kernels, 5.1 is on its way.  (Phoronix)

  • Optane DIMM pricing has leaked some more.  It is mostly in "if you have to ask" territory.  (Tom's Hardware)

    To be fair, buying 24TB of DDR4 RAM is not cheap either.

  • MIT Technology Review provides some uninvited woker-than-thou advice to Google.

    Burn academia to the ground.  No exceptions.

1 Optane:  We already knew this, sort of, but those bandwidth numbers are painful. Presumably you wouldn't use this stuff anywhere performance is desirable.
Facebook:  I don't know anything about this John Edwards guy, but this sounds like a stopped-clock moment (or a blind squirrel finding a nut, whatever.)

2 The sequential write is surprisingly bad.  There are consumer SSDs that are faster, at $250 per TB.  Of course, those have a block size of 4K vs. probably 32 bytes for these DIMMs, but for sequential access that shouldn't matter.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
