spark and presto have big farms of workers. it's a replacement for the part that owns the memory where the computations happen on the workers. it has a handful of fast support libraries and i/o libraries but can also make use of s

rfc 822 local-parts (stuff to the left of @) are weirdly permissive. you can include quoted spaces, carriage returns and newlines (!)

what was it again? export CVS_RSH=ssh -z9 sourcesafe was trash. i migrated a pretty massive project off of it (browser, os, several bsps) and like 30% of the revisions were irretrievable.

dns runs on port 53. the rpcbind service on 111. pop and imap, both privileged, even with ssl enabled can take usernames and passwords. making this sort of change in any installer script is a terrible idea.

by a-dub 4y ago
no, i disagree. privileged ports should not be removed from linux to make a javascript webserver more secure or easier to setup.

so if i install a recommended mozilla add-on like ublock origin that has an extreme permission like "access your data for all websites" does that mean that every update to the add-on sees rigorous security review by mozilla befor

lenovo p1 is basically an intel mbp 15. camera and audio aren't as good as the mac, although i hear the camera has improved in later generations. bigger issue is that the nvidia graphics are wired to the thunderbolt ports, so if you wa

in this sort of scenario you would detect the error by a failure to see an increase in temperature over some interval. the trigger functions typically would just raise dio lines high which is not something that really fails unless you'

i remember this was possible on thinkpads and linux with a custom pam library like ten years ago. it was fun to set up, but not really worth maintaining.

matlab or octave (oss clone) may be of interest to you. for symbolic math try wolfram alpha, the matlab symbolic math toolbox or one of the symbolic math packages available for python.

i love how the low bits of the addresses in hex are cognates for both the section and the actual content of the name/line. also, looking glasses... jeez. i haven't heard or thought of those in _years_.

that's basically what it does, it finds peaks relative to total power. you can think of it as like identifying continents by constellations of mountain tops which is robust to whatever chaos might be happening at sea level.

i haven't looked yet but i'm going to guess: edge caching running on custom hardware with smart predictions and congestion control algorithms for determining what gets cached where and when.

it was a cool idea, but i don't remember even seeing it implemented in spdy which is where i believe it came from.

i think it's probably coming back with this whole low-code/no-code thing.

yeah, maybe you're right. it does, however, seem to share something with basic science: it's an endeavor with no immediate or obvious value, yet expands the frontiers of knowledge and know-how for the species as a whole.

the idea of going to mars is basic science, and basic science has yielded all sorts of useful discoveries for the human race. but it is also hard to ignore the fact that it seems circular to turn the earth into something that looks like mar

honestly iphones seem to last the longest both in terms of durability and longevity of security patches. starting with the pixel 6, the pixels now see security updates for 5 years (instead of 2? 3?) though. other android phones are a bit sc

yeah, just pointing out that there's nothing inherently wrong with hdf5 and that the gains you speak of are likely from just from the use of modern compression standards. maybe there's room for a simplified standard... or maybe ju

hdf5+zstd would likely be comparable. good luck loading those pickle files 5y from now.

i just reread about the retina and i think you are correct. i was under the false impression that the transfer function for each group of cones was a function of some processing in higher layers of the ventral stream.

by a-dub 4y ago
even though all the metadata is weird and overengineered, i would probably still use hdf5 as it provides for interop with other numerical computing environments (matlab, julia). also hdf5 is at least securable. pickle streams are not design
