i know don't have knowledge subject have questions can understand how graphics app work , please correct me cause i'm sure have mistakes. why normal ui app works without lags when comes drawing animation , other stuff , doesn't use gpu @ all. games using opengl , directx uses gpu draw objects. wondering if because 3d objects should rendered rendered 2d image before being displayed , guess gpu job. why can't cpu job instead? makes gpu better rendering components in 3d game? but why can't cpu job instead? makes gpu better rendering components in 3d game? the cpu can render 3d graphics. , there 3d games before gpus or other 3d graphics chips existed, did. what's thought seminal 3d game, quake, written cpus rendering. specialized hardware 3d rendering exists same reason there specialized hardware on cpu ieee-754 floating-point computations: can faster special hardware through emulated instructions. though there different reasons it. renderin...

i'm transcribing audio file speech api , shows confidence level top result. there field can add config json can see confidence levels of alternative results? below have config right now(in python) config = types.recognitionconfig( encoding=enums.recognitionconfig.audioencoding.flac, sample_rate_hertz=44100, language_code='en-us', speech_contexts=[speech.types.speechcontext( phrases=['low'] )])

for example below, based on how bits.b.a set value of bits.byte, mean head of bit-field? know machine little-endian doesn't mean least significant bit or significant bit. there better way determine order of bit-field through coding? struct bit_fields { unsigned int a:4, b:8, c:20; } union myunion { bit_fields b; uint8_t byte; } int main(void) { union myunion bits; bits.byte=1; printf("%u, %u, %u\n", bits.b.a, bits.b.b, bits.b.c); return 0; } output: 1, (random int less 2^8), (random int less 2^20)

say have weighted, undirected graph x vertices. i'm looking separate these nodes clusters, based on weight of edge between each connected vertex (lower weight = closer together). i hoping use algorithm k means clustering achieve this, seems k means requires data in @ least 2d space, while have weights of each edge go from. is there way cluster nodes of weighted graph together? don't have preference whether need specify number of clusters or not. i suspect i'm missing relatively simple here, rather late. i've considered whether need traverse graph, , each node find y closest immediate neighbours, seems simple. edit: apologies: more specific: graph isn't large (around 150 vertices, maximum), , not complete. i'm using python.
