are you expecting any similar messages from guido re python @jasonbell?
“All I said was I though that Python wasn’t fit for purpose at scale, I didn’t expect some form of Spanish Inquisition”
I then upset every DBA in the room when I suggested using only in memory databases and who needs SQL when maps of data is fine 🙂
i'm still waiting for our shiny future where all RAM is NVRAM and the artificial in-memory / on-filesystem distinction disappears forever
just use a single level storage machine like an AS/400 and all those problems disappear.
that's not really single-level storage is it @thomas - but a vm-like abstraction which appears that way?
true... from a program perspective there isn't any difference whether it is stored in RAM or a disk. But one could argue that is (HW) implementation specific.
depends on the program - e.g. if you are implementing a db and you know that your indexes are not really all RAM-resident then you will still need to make some effort to make sure that things which are likely to be accessed together are stored together, whereas if you know that all your RAM is really NVRAM then you can forget about that
If you’re really pursuing performance though you can’t be oblivious to L1/L2/L3 caches either - I’m guessing they still exist on AS/400s 🙂
Unless of course this is the future we’re going to get 🙂: http://erikdemaine.org/papers/BRICS2002/paper.pdf
Which seems like a fascinating area of research
hahaha
I wish I had seen that
Sadly @alex.lynham it won’t have the same effect on Monday
If @thomas strips down to his underpants during my talk I will complain to the authorities.
