iptables on Ubuntu 10.04
Jul 31st
I’ve always had issues with using iptables on Ubuntu. Why they make it such a pain in the butt to work with iptables is beyond me. That said, if you’re using Ubuntu 10.04 the normal ‘iptables save’ does not seem to work the way it think should. It seems to require an extra parameter for it to save correctly.
Running the following should save your chains and rules and make them available for when the system or iptables itself is restarted:
/etc/init.d/iptables save active
I am not too sure why this extra bit is needed as our Gentoo servers and even our Debian server simply allows just the save command to be used. However, I hope others find the above useful when working with iptables in Ubuntu. I am hoping the Ubuntu team fixes this (as well as the init.d scripts from the client version of Ubuntu if they haven’t already). I really hope even with the introduction of the ‘ufw’ (Ubuntu Firewall) software they don’t dumb down the functionality of iptables to where someone who knows what they’re doing is no longer able to do so.

Google Chrome OS
Nov 20th
Someone posted a link to the Google Chrome OS on Twitter this afternoon. Since it was for either VMWare or VirtualBox, I thought why not give it a go? The download itself is about 300MBs and was really quick. However, the VirtualBox image from GDGT didn’t work for me, so I ended up snagging this image instead. This one did work. You should note that these builds weren’t compiled by me or people at Google by but someone else. You may wish to make yourself an extra Gmail/Google account to try this out.
Please note, if you’re getting the “No Network Connection, Offline Login Failed” you might want to try restarting the virtual machine or even your computer. Restarting my computer seemed to fix the issue, I believe that VirtualBox doesn’t complete it’s network (virtual adapters) setup until your computer is restarted but I could be wrong. Once you’ve actually gotten the image to boot you’re prompted to login. use your GMail account info, or if you have a normal Google account (@Google.com) this will work as well.
Upon logging into the system, you’re basically presented with the Google Chrome web browser. This is pretty much it. There’s a Google Short links, which I assume will basically give you short cuts to all the Google Apps (Docs, Sites, Calendar, Gmail, etc…), but yeah that’s pretty much it. Seeing as how this is probably pre-alpha, I guess it’s a start in the right direction. I am not sure what the final goal for the Chrome OS is, whether it be simply a portal to your Google applications or a bit more of a fully featured OS. It may indeed simply be something you toss on a netbook, boot into and have almost instant access to your calendars, emails, documents from Google, but I am not sure.
Apparently you also cannot change the resolution, so you’re stuck at the awful 800×600 for the moment. There’s not much tweaking you can do to the system, you can see the battery status (which makes me think this is geared to netbooks/notebooks, and you can check on the network status (see if WiFi/Ethernet is connected or not). You can also play with the settings of the web browser (which is essentially the only thing on the system haha). That said, it’s a neat idea and I certainly wouldn’t mind tossing this on one of my netbooks when it goes final. When I use my netbook I’m never usually doing anything outside of my web browser, unless it’s in a terminal so this would work quite well. I’m definitely excited to see it develop and mature!
Google Wave – Flatline :(
Oct 20th
Ever since I heard about Google Wave back in the Spring, I was super excited to get my hands on it to play with. Finally last week I got my invite and I started playing with it right away. Unfortunately, the playing with lasted only about 20 minutes. I honestly cannot figure out what to use Google Wave for. Currently I have 5 or 6 Waves which really seem to be conversations about, what wave is and how we should be using it.
At this time, I guess I am not really sure what to think of Google Wave. The issue could simply be that there’s not enough people that I know on Wave, so using it at the moment, or at least using it to its full potential is just not possible. I can certainly see how one can use Google Wave under the right circumstances, and it sure looks like it might be a great tool for collaborating on projects. I am hoping that within the next 6 months, I am able to actually use the product. I feel quite let down at the moment, so I am really hoping Google comes through on this! Lots of big hype but nothing super fantastic yet :(
