comment Identify machine configuration via code
Agreed /proc/cpuinfo is a good place to look for info about CPUs, but user855 asked about disks - lsblk is a better option for that. Where to look for info? tldp, google, /usr/share/doc

comment Linux cache evictions
thanks, nice article. Any idea what book the chapter comes from? However, although it explains how a particular page is prioritized for eviction, it does not really explain why pages are evicted when there is no apparent demand for memory. What controls the process "to shrink the cache to make available more RAM for other uses"? What is it replacing these with?

comment Linux cache evictions
Thanks Joe, however the first 2 options specifically relate to data which needs to be written back to the filesystem (i.e. the write buffer) not data which has been read and has not been changed (the read buffer). The vfs_cache_pressure controls the preference for evicting file metadata relative to file contents.

comment Linux to linux USB storage?
aware of infiniband - but hardware is only cheap off eBay, requires expensive cabling too and I've only ever seen PCI[e] host adapters. Further, this means running the data on top of TCP/IP with all the complications regarding congestion avoidance. Thanks for the link though.

comment Linux to linux USB storage?
cablewholesale.com/support/technical_articles/… says "will allow for two host devices to be connected directly with a USB 3.0 crossover cable" and it seems that these are available.

comment Linux to linux USB storage?
That was my concern - finding the hardware (since posting I found this: linux-usb.org/gadget/file_storage.html which seems to solve the software problem)

comment CUPS denies access to printer
No, none of the config is changed (and nothing noted in cups logs) when I run lpadmin. The classes file is empty and printers.conf has nothing relating to browsing/access control.

comment How to migrate files on Linux from HDD to SSD on a VDS
Some applications don't like symlinks in certain contexts - e.g. opinting your document_root in apache to a symlink will result in lots of 404 errors if you've configure -FollowSymLinks. Further you may run into concurrency issues if the same file is accessed via different paths. NB I'm not saying this is not the way to fox the problem, just that there are hidden gremlins with symlinks.
