Can I upgrade to windows 7? Here is how to check

In our testing at Corneredge Windows 7 has performed well.  I’ve already loaded it on two machines that could not even run Vista and they are running great.

SO, I’m tempted planning to upgrade my workstation.  Microsoft seems to have really done their homework with the upgrade this time, and I’m looking forward to the features in windows 7.

If you are thinking the same way, download this tool to get a nice checklist of what you need to do before installing windows 7.

Trace a DNS lookup path

While working through some DNS lookup inconsistency today, I was reminded of this tip that allows you to trace an entire DNS lookup.  Normally I just do an NSlookup, but I wanted more information.   DIG is a command that’s built into Linux (and therefore MAC) So I hopped on my Mac and ran the command like this:

>Dig +trace http://www.yourdomain.com

results look like this:

How to virtualize an old computer

As developers and systems engineers we use an immense amount of software tools and applications.  Transfering to using a new computer seems like it can take months before you have “all you need” for our daily tasks.

When I took delivery of my new laptop in January I struggled with this issue.  My old machine had been in place for 3 years and now I was faced with starting fresh.  64-bit Vista on my laptop also presented a challenge for old applications I used.  Not to mention that old PCanywhere, old VPN connections, etc…

SO, I decided to virtualize my old laptop.  I can litterally run that computer in VMware faster than I could before, and I don’t have to worry about old applications or old VPN configurations for customers, they all just work!

So how do you do it?  Simply install the free Vmware converter on the machine you want to virtualize and point it to your nearest VMWare workstaion or server.  I highly recommend this, it was a truely painless process.

Trade your netbook for speed, size and performance

Netbooks might be convenient, but they are slow, too small, and lack the performance you really need to crank things out.

I agree with Michael Dell’s assessment here, netbooks are just smaller accessories to real machines you need.

Real laptops are becoming so fast and economical that netbooks will soon be un-necessary as well.

Postini mail delays and Google sustainability?

Postini (Owned by Google since 2007) is a great hosted email and archiving service for email that many businesses rely on for security, spam filtering, and email storage.

There have been increasing delays reported Tuesday (10/13) this past week of up to 4 hours with email and very overloaded support etc… customers have been very frustrated.  Google is working on resolving the delays and has finally communicated acknowledgement of the situation and are working as fast as possible to fix it.  If you are a customer experiencing a problem, please go to the Postini Support Portal to work with them directly on it.

This begs the question again this month… Are these widely used and free application services really safe to rely on for your business?  Is the Google model sustainable?  Could you afford a 4 hour delay on email yesterday?  I’d like to say, sure, I’ll pick up the phone, but in this economy that could really hurt.
