My first computer was a Radio Shack Color Computer 3 - 6809-based, running OS-9 Level II. It could run 32 processes at once, due to bank-switching a whole 1 Meg of memory.

After that, I got an AT&T 3b2, also known as a Convergent Safari. This was a Motorola 68010-based desktop.

Then, I graduated to a NeXT black&white "slab". I bought a used SPARCStation IPC in 1995, and put NetBSD 0.9 on it.

I've been using Linux since 1997, starting with a DEC Alpha-based UDB, and downgrading to a x86 PC in 2002.

I run Slackware and Arch linux.

Aug 13	comment	How to check if NTPD updates Linux machine's time successfully using shell? This is the first instance I've heard of anyone monitoring system time. Excellent answer.
Aug 12	comment	How to check if NTPD updates Linux machine's time successfully using shell? I should also mention that the code fragment you posted should get run at or above runlevel 3 during the boot. ntpdate sets the system clock, then ntpd becomes a daemon process, and keeps the clock synched to the servers. Ordinarily, you don't run those 2 lines of code to just "set the clock".
Aug 12	comment	How to check if NTPD updates Linux machine's time successfully using shell? ntpd is a daemon process - it runs continuously. It decides how often to ask a server for current time, and how often and how much to change the local clock, based on how the local clock drifts: you can't really control any of the intervals. ntpd runs in the background. To change an NTP server, you edit /etc/ntp.conf, and stop then start ntpd.

Aug 12	comment	How are directories implemented in Unix filesystems? +1 for the incredible historical code.
Aug 12	comment	How are directories implemented in Unix filesystems? Directories are traditionally just specially formatted files, but that's no longer true: en.wikipedia.org/wiki/ReiserFS#Design In ReiserFS and some others, directories are entries in a database. Directories may act as arrays, but that's just the programming abstraction.

Jul 25	comment	Kill process when it stops to produce further output "Stops producing output" is a very vague criteria. The vagaries of OS scheduling mean that even a program that does nothing but write bytes out will occasionally "stop producing output" when other processes get scheduled. Any I/O buffering, in stdlib or something, will also produce "bursts" of output. You should find a different criteria for restarting.

Jul 19	comment	Using data read from a pipe instead than from a file in command options This could be problematic if `command` believes it has all the file names it will need on the command line all at once. Some versions of xargs will give `command` a few file names (10, it seems to me) at a time. Looks like GNU xargs gives everything all at once.
Jul 15	comment	I can create a file but I can't read from it Ensure that user ID apache actually has the correct path to the file. You used a relative path ("tmp/QQ") in your example. Does the process in question have a working directory of whatever "tmp/" appears in? Does the process in question try to read the file by a fully-qualified name or something else?
