so what happens when your ipod dies? what if you get a new one and simply have no use for your old one? if you don’t have a use for your ipod or it is broken and you have determined that it’s a model with a hard drive and it is still in working condition, you can simply turn it into an external hard drive. i had a 5th gen video ipod that had a circuit board go bad and it already had a battery that wouldn’t hold a charge. instead of buying parts to repair it, it just went ahead and bought a new one. ...

i’ve seen tons of posts around the internet regarding backing up itunes. most of them seem to focus on backing up your itunes library. while this is great, it doesn’t cover everything you probably want to back up when doing something like a complete reinstall of windows. if you only back up your library, you will lose your settings as well as your playlists. if you are like me, you have your music stored on a central server somewhere so backing up your music on your local computer is pointless anyway. ...

when i am at work, i use a ssh tunnel when i need to bypass the proxy server. this works great except for when i visit certain sites with a large number of big images. one site would be boston.com - the big picture. it has a large number of high quality images and the ssh tunnel just doesn’t seem to be able to handle the traffic. when the number of http requests overloads the ssh tunnel and then i get the message ’network error: software caused connection abort’ as seen below. ...

i have owned an acer travelmate 2420 for about 5-6 years or so and i have noticed, especially more recently, that my cpu temperatures were pretty high. the cpu would idle around 60-65°C. a couple years ago, i started taking the laptop apart to see if there was access to the processor to reapply the thermal paste. turned out that it wasn’t so easy to get to so i simply gave up since i couldn’t find a service manual for it anywhere online. since the temps seemed to keep getting worse, i decided to try to look again. ...

as many people are aware, many ISPs block traffic on port 25 in order to attempt to prevent spammers from using bot infected hosts on their networks. this can be a problem for people who want to run a mail server from their home connection. yes, i realize that running an email server violates the TOS of most providers but that is a discussion for another day. i personally use my email server as a learning experience but i also use it for my primary personal email. ...

continued from part 1 yesterday i received my soekris engineering net4801-60 in the mail. the unit seems to be in good condition and even came with a compactflash card and vpn1411 card which i won’t end up using. i will most likely end up selling the vpn card as i don’t use my smoothwall to create a vpn and the smoothwall os does not have support built into the kernel for a vpn card such as this anyway. ...

even though all of my parts have not arrived for my new smoothwall project, i can begin to do some initial setup. first of all, here are all of the items of which i needed to find for the project: soekris engineering net4801-60 soekris engineering 2.5" hdd mounting kit soekris engineering power supply 2.5" ide hard drive 10 foot serial null modem cable since i already have the hard drive, i can do some of the prep work by installing smoothwall. i am using an old laptop to install the os to the hard drive. luckily linux is much less picky than windows about changing hardware after installing. i downloaded and burnt a copy of the latest smoothwall 3.0 sp1. installing smoothwall is about as straight forward as things come. just follow the steps on the screen until you get to the “Network configuration menu”. since we currently do not have the correct network cards in the computer, this part is going to be overwritten later. ...

like many people, i like to tinker with all sorts of different technology including multiple operating systems as well as the different roles they can play. one of the best ways that i can do that is by using a virtualization product. i just happen to use vmware server 2.0 on my debian lenny server. vmware is one of the leaders in virtualization (if not the leader). at home, i have five virtual machines that i rely on heavily for my day-to-day operations. i have two windows server 2008 domain controllers, two windows server 2003 servers running exchange 2003 and one windows server 2008 computer i use for remote desktop and management of services. some of these services can provide a fair load on my server and i was starting to see the impact, especially from my win2k8 vms. it seems that there are a number of optimizations that are not enabled by default in vmware server. i searched far and wide through vmware kb docs as well as blogs and web forums and came up with the following optimizations: ...

i’ve decided to look more into power efficiency of my computers at home. while my power bill isn’t horrible, it could most definitely be lower. there are only a few computers that i leave running 24/7. one of them is my smoothwall. while i built that computer with power efficiency in mind, i didn’t take things to the extreme that i could have. now i want to build a solution that is closer in power consumption to your typical home router appliance. after doing some research, i found a solution that would not only be power efficient but also cost effective. the solution is the soekris engineering net4801. ...
