Windows 7 Experience Index Performance on the Atom-powered, Asus 1005HA Netbook

The question of “How does Windows 7 run on ………….” is often asked.

I’ve been running an Asus Seashell 1005HA (6-Cell Battery, 63Wh) with Windows 7 for some time now, and use it as my main machine 90% of the time.

Just as a side note, the only thing I have done is upgraded the RAM to 2GB (from the standard 1GB) by adding a single 1GB SO-DIMM to the Netbook.  For the cost and how easy it was, it was well worth the upgrade!

The Windows 7 Experience Index is often a good guide to see how a machine will perform (processor, memory (RAM), graphics, hard disk) – the results for this Netbook are below:

mtr: A Better traceroute and ping, combined! (Linux, BSD)

mtr is an small utility which combines both the functionality of traceroute and ping, for Linux and BSD.

There are always occasions where you’ve wanted to traceroute to a host, possibly due to connectivity issues, and you need to diagnose where the problem lies.  Most operating systems offer basic traceroute and ping utilities, but what if you need something a little bit better?  mtr is the answer..

mtr allows you to start a ping/traceroute to a host, and it constantly updates on screen with the latest ping times to every hop along the way, giving you a great view to exactly what’s going on.

Traditional traceroute, for example, only runs once through the route, and gives a view of that moment in time – with the constant updates in mtr, you don’t have this limitation.  And, with mtr‘s ping functionality inbuilt to the main view, no longer do you need to run multiple command prompts/terminals to see what’s going on.

So if you use Linux or BSD, and you find yourself regularly testing various routing issues, ping times, or just general network diagnosis, give mtr a try.

For packages/installation, please refer to the inbuilt packaging system of your operating system (Debian/Ubuntu users, mtr is available from the standard repositories).  If mtr is not available as a package, you can download the source (GPL) from here:  http://www.bitwizard.nl/mtr/

SSH Access Whilst on the Move (iPhone, iPod Touch)

If  like me you maintain servers and use Secure Shell (SSH) as the primary method of connecting to them, you’ll know the importance of being able to connect to those servers, no matter where you are, to either make changes, monitor them, or fix any problems.

If you have an iPhone, you can connect to those servers whilst on the move, using a great application called TouchTerm SSH (available in the AppStore).  The application works over the data connection (Edge/3G) or WiFi. TouchTerm also works with the iPod Touch, so if you have WiFi access, you can also connect to remote SSH servers using this application.

There are two versions of TouchTerm SSH – a standard version and a pro version.  I personally have the standard version as it does everything I need it to do, but you may find the Pro version more suited to what you need (Gestures and Text Completion are just two features of many only found in the Pro version.)

TouchTerm has some clever and well thought out features, such as the transparent keyboard which maximises the small screen usage – there’s not much space on the iPhone screen for a full console and keyboard, but with the keyboard being transparent, it’s pretty easy to use and still see what’s going on behind it. There’s also a very useful toolbar, which allows you to send important modifer keys allowing access to features such as “Ctrl-A (then c)” to detach a screen session.  The keys on the toolbar are: Ctrl, Alt, Tab, Esc, Ret, ^C (for quick Ctrl-C access!).

I’ve tested it with my servers, and it’s certainly very usable for quick admin tasks, when I’m not at a computer.  I’ve even found myself having a quick tail -f of apache logs whilst walking around the house to see if any traffic is hitting a site!

So, if you look after a box (or many boxen) with SSH access, and have an iPhone/iPod Touch, give TouchTerm a go – I think you’ll be suprised at how useful the application is.
