[9fans] PostScript rendering on Plan9

2012-03-06 Thread tlaronde
Hello, Just for my information, on what version of, I think, Ghostscript, Plan9 PostScript rendering is based? Because, under Plan9, the rendering for example of the AMS-TeX guide (the package AMS-TeX for kerTeX has been added) is absolutely beautiful, while the same thing rendered on an Unix wit

[9fans] pxeboot & tftpd

2012-03-06 Thread Jeff Sickel
I've been taking the time to finally setup pxeboot for a few new projects. Oddly, or maybe not, I'm wanting to run dhcpd and tftpd on /net.alt instead of /net. Doing so highlights a subtle point that I've clearly missed in the whole namespace documentation and network configuration. ip/dhcpd

i tried another device a bit ago. openrd (kw). with and without setting the interrupt delay to 1 microframe. i get just about the same times (a little higher). does anybody get less than 10 sec for dd -if /dev/sdU0.0/data -of /dev/null -count 1024 -bs 65536 ? or even less than 20 sec? that is, i

a little reading later. the usb mass storage bulk only spec stipulates that only one request may be active at a time. wince. so, bigger buffer? yup, 32k reads double the speed again. 64k reads aren't quite right, something clips it's tail. now i'm up to ~11 MB/s. except that it crashes the pc
