May 7	answered	What considerations need to be made when choosing the version of kernel for an embedded device?
Jan 30	comment	Find any lines exceeding a certain length mawk runs the length function quite a bit faster than the gnu awk, might try that.
Jan 14	answered	Using ramfs on embedded system
Jan 4	comment	Xterm with Solarized only showing dark background without font colors Interesting, but could you expand on what does it affect exactly?
Nov 9	comment	Preserve scroll on Linux console switch FreeBSD doesn't have this problem, each VT has it's own scrollback buffer I am guessing.
Nov 5	comment	How many rings does OpenBSD use? STOP used to have 3 rings, but I think the newest version was reduced to 2 for the sake of speed :(
Oct 12	comment	How to use a custom crypto algorithm in ipsec? First Law of Cryptography: Thou shall not roll your own crypto. Sorry, someone had to say it ;)
Oct 12	comment	Fastest ssh X tunneling on a local secure network Yup, this agrees with my findings: security.stackexchange.com/questions/12901/…
Sep 6	comment	CentOS: Install packages listed in a text file? This is much nicer, as it will look at all the dependencies at the same time, instead of figuring them out for every single package.
Sep 6	comment	How to merge output of two running log files in real-time `multitail` has few relevant flags: `--mergeall`, and `-ts` As for enforcing time coherence, I've done it once, but it had to be done by every log line having a timestamp, and then wrote an awk script to rearrange the entries to be sorted by time. That's nowhere near real-time. The lesson learned on that one was that the timestamps had to be generated by the program generating them, and not the logger program, as they tend to be heavily buffered, which demolishes any notion of decent timestamping.
Aug 17	awarded	Yearling
Jul 19	comment	How to print only last column? +1 for double rev, but as a side note, `rev` does not work with 'wide' characters, only single byte ones, as far as I know.
Jul 19	comment	vi/vim, how can I write out a number of lines to a new file Are the addresses inclusive or exclusive?
Jul 5	comment	force re-negotiation of PCIe speed on Linux In windows I've seen it change automatically, it's a function of pci-e bus power-saving. serverfault.com/questions/226319/what-does-pcie-aspm-do seems to have a nice explanation
May 16	comment	Which edac module should I enable here? @cjm, not anymore. Memory controller on all Nehalem and newer is built into the CPU, not the North Bridge. So as long as the motherboard supports it (need more wires from memory to CPU since ECC uses 9 bits to store 8 bits with the extra redundancy), plugging in different CPU's can give you the ECC capability.
Mar 23	answered	Can someone recommend a Linux Distro for purposes of just running a DNS?
Feb 15	answered	Can I use pxelinux to boot from an ISOs over the network?
Feb 15	answered	Tool for measuring entropy quality?
Jan 20	comment	FreeNAS versus a regular (CentOS/Ubuntu) linux server? Not hard at all, there are some unique conventions & mechanisms, but ultimately it's Unix-relatives, so it's still plain text configs, command-line, files, and pipeline processing. Everything else is 'syntactical sugar' ;) Once you set it up, you won't even notice.
Jan 19	comment	FreeNAS versus a regular (CentOS/Ubuntu) linux server? Frankly, I don't remember anymore, I had two experiments going at the same time, one at work and another at home, so there was a lot of distros/hardware/configs tossed around.
