i found piece of code in css file inherited, can't make sense out of it: @media screen , (max-width: 1024px){ img.bg { left: 50%; margin-left: -512px; } } specifically, happening on first line? that’s media query. prevents css inside being run unless browser passes tests contains. the tests in media query are: @media screen — browser identifies being in “screen” category. means browser considers desktop-class — opposed e.g. older mobile phone browser (note iphone, , other smartphone browsers, do identify being in screen category), or screenreader — , it’s displaying page on-screen, rather printing it. max-width: 1024px — width of browser window (including scroll bar) 1024 pixels or less. ( css pixels, not device pixels .) that second test suggests intended limit css ipad, iphone, , similar devices (because older browsers don’t support max-width in media queries, , lot of desktop browsers run wider 1024 pixels). however, apply des...

a.why there many wait states in in vms/vax process states ? all of waits except 1 have memory swapping or thread swapping. the vax architecture had virtual addressing. program access 1 gigabyte of address space, huge in 1977. if remember correctly, 32 or 64 megabytes of memory standard. meant programs access more memory machine had. vax managed virtual memory paging memory , disk drive. multiple users use vax. accomplished multiple user threads. since processor execute 1 instruction @ time, 1 thread active @ time. generally, thread run until i/o instruction encountered. thread swapped out, , other threads allowed execute, while i/o instruction completed. if want feel in olden days, read tracy kidder's "soul of new machine". it's story of team developed data general eclipse mv/8000 .
