the state-of-good-repair grift will continue until the morale improves! SelTrac is fine. and if it ever actually breaks (dubious) they can fall back to block signaling which comfortably handles more trains than muni is capable of running.

they were off the shelf into caltrain got their grubby hands into the procurement process! they are about twice as powerful as standard KISSs. also stadler had to install an extra powerful air compressor so they can ding their fucking bell

idk "it's in a bucket forever" sounds like a pretty good remediation strategy to me. dollar-for-dollar that government money probably has more impactful things to do. eg plastering public spaces in cities with bollards (see t

yup. molecular dynamics simulations are hard-core. and the parallelization is highly non-trivial so you need fast fabrics and complex message passing to scale. one of the raisons d'être for supercomputers

they still emit tire particulate emissions. moreso than ICE vehicles due to the increased weight

the long term point is to understand how the brain works. hope that helps.

??? the gradient coils make the noise, and due to field homogeneity requirements, it is safe to assume the superconducting coil is not moved by the gradient coils

shalizi is overwhelmingly charming. i have wanted to work with him for years, as much for the whimsy of his website as our overlap in research interests

the brain like computer one was also quite off. however neuroscience is both vastly more complex and less accessible to the layman than photolithography, so i'm all too happy to let the Gell-Mann amnesia wash over me and enjoy some dec

you can hookup the panasonic unit to a window manifold for a portable AC and put some insulation board over that. that is the only reasonable solution I have found for the states

that's a horrible idea. careless use of machine learning in medicine is one of the few legitimate "AI safety" cases worthy of concern. ML is far too unreliable and doctors too illiterate for medical imagery diagnostics to be

buy the reels and channels waveform sells, solder them together and connect a power supply.

to regulate circadian rhythm you want something that hits melanopsin, which is optimally excited at 484 nm. most LEDs have a gap in the spectrum there. like another commenter mentioned, waveform has some good products with engineered phosph

modern houses should be well-insulated, using heat exchange ventilators and heat pumps get proportionately more efficient in these conditions. i will be shocked if this is ever viable economically.

is this schmidhuber's alt? sure they existed before AlexNet was where it really took off. just look at the number of citations. right paper, right time. CNNs were uniquely suited to the hardware at the time. because of their efficiency
