out of memory during a gentoo emerge?

If you are running out of memory, you may want to increase your swap memory. 

swapon -s

if it is empty it means you don't have any swap enabled. To add a 1GB swap:

dd if=/dev/zero of=/swapfile bs=1024 count=1024k
mkswap /swapfile
swapon /swapfile

lamp config on gentoo

emerge mysql
emerge apache
echo "dev-lang/php apache2" >> /etc/portage/package.use
echo "dev-lang/php mysql" >> /etc/portage/package.use
emerge dev-lang/php

/etc/conf.d/apache2 should have -D PHP5

Visual Studio and Silverlight Launch

Just got back from the Visual Studio 2010 and Silverlight 4.0 launch in Vegas.
Man what a learning curve ahead of me as I try and get my head around some totally new concepts.

WPF (Windows Presentation Foundation)
WCF (Windows Communication Framework)

I'll post an update to this once I've settled in.

the /dev/socksys disappearing trick

For the past couple of months I’ve been manually creating /dev/socksys on my development virtual machine only for it to disappear when I reboot.

The reason for this is that /dev is now regarded as a virtual directory and is rebuilt by udev from scratch every time the system is rebooted.

The solution to this is to cp -R [device] /lib/udev/devices.

When you reboot you will find the device in /dev.

mknod /dev/socksys c 30 0
chmod 777 /dev/socksys
chmod +s /dev/socksys

cp -R /dev/socksys /lib/udev/devices

Deleting a Vista Directory you don't have access to.

I use delta copy on Vista ultimate to backup several windows machines as well as my cvs repository on Linux. I inadvertedly configured the service to start as a network service but found I couldn't access the backup at all. I subsequently changed it to start as my user and could access the new directories but was left with a backup directory I couldn't access or delete.

This is how I eventually managed to delete the directory.

Start accessories right click on the command prompt and select run as administrator. At the command line type

takeown /F [directory] /R

cd [directory]

cacls *.* /T /G "[PC NAME\USER NAME]" :F

cd ..

rd [directory] /s

proxy usage?

Quick script to give me usage for a particular url on my proxy server.

usage.sh URL

# !/bin/sh
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.9 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' > $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.8 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.7 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.6 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.5 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.4 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.3 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.2 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log.1 | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log
perl -pe 's/[d.]+/localtime($&)/e' /var/log/squid/access.log | grep -i $1 | awk '{ print $1" "$3"-"$2"-"$5" "$4" "$7" "$11}' >> $1.log

Gives the result set in URL.log
