comment How do I prevent Linux from freezing when out of memory?
With or without swap it still freezes before the OOM killer gets run automatically. This is really a kernel bug that should be fixed (i.e. run OOM killer earlier, before dropping all disk cache). Unfortunately kernel developers and a lot of other folk fail to see the problem. Common suggestions such as disable/enable swap, buy more RAM, run less processes, set limits etc. do not address the underlying problem that the kernel's low memory handling sucks camel's balls. Meanwhile, I suggest running the OOM killer manually (SysRq-F) when the system freezes as that will make it recover faster.

No help here either, system still goes completely unresponsive.

comment Can you set a minimum linux disk buffer size?
Does not solve the actual problem which is a combination of not being to set proper memory usage limits (ulimits are not very useful), applications easily going havoc with memory allocations, the OOM killer failing to fire early enough and the massive disk trashing and unresponsiveness caused by all that. I just wasted 30 minutes of my employer's time because the development machine would trash the disk for half an hour while compiling my code, instead of simply killing the Chromium processes it needed to kill (or the compile itself) in less than a second and then be done with it.

comment How to make Windows 7 USB flash install media from Linux?
Doesn't work for me either and my machine does support USB booting just fine. Maybe this approach can work on machines that can boot DVD-style USB-storage but most BIOSes assume HDD-style layout on USB (meaning 512 byte MBR with boot code in it). On thing worth a mention: Fedora CD/DVD images, unlike W7, do in fact have such MBR with boot code and partition table on them, making them suitable for HDD/USB boot too.
