The new iPad hype
Jan 29th
What’s the issue really?
Oh noes, no camera? That’ll change I bet.
No flash? Win in my book!
No multitasking? Really, you wanna run more things, buy a computer.
Now, the speculation about version 2 makes me laugh, but really, aren’t we at version 3? In my office common area, I have version 1, and I’ll include a picture.
Back to the iPad – just sit back and see what really happens. We are 60-90 days out (minimum) before it hits the shelves, maybe a surprise will come. Like tether-ability! That’d be win.
And as promised…and yes, it still works, and is not for sale.
For those about to write..
UNIX Shell services, what’s the fuss?
Jan 21st
Wowzers, quite a little thread going on in a newsgroup, but really, what’s the big deal?
I think I know…
Not everyone uses the Internet for viewing web pages and downloading pr0nself-help videos and television shows. The Internet itself has become much easier for the layman to use, and with that, these historical services are no longer needed and support for them is harder and harder to come by.
In the past, most service providers (especially the ISPs that service residential users) used to offer some kind of UNIX shell for their paying clientele. Over time, the number of service providers has decreased, and of those that are left, the percentage of them that offer this type of environment has decreased by orders of magnitude. I’ll speculate on why further down this post.
UNIX shells are fascinating experiments in shared computing resources with a very long history.
Over Subscription vs Over Capacity – huh?
Jan 15th
Recently, a whole slew of tweets showed up across my feed dealing with the perceived and measured issues across multiple public cloud providers infrastructure.

One of the posts comes from Chris Hoff (this post in particular) that describes quite clearly what the differences are.
Service providers (anyone doing cloud services, virtualization, colocation, bandwidth, whatever) live upon the idea of over subscription. We make our revenue banking on the fact that not everyone needs their full allotment all the time.
With over subscription there is a chance of reaching a state of over capacity. Anyone using this business model needs to understand that they must be ready for it to happen. It isn’t an issue of ‘will’ but an issue of ‘when’. Good engineering can keep the ‘when’ at bay, virtually forever, and that is what you need to be prepared for.
Another recent posting via The Register (featuring @GeorgeReese) had some data dealing with network latency within the Amazon EC2 network. I don’t have any opinions about what was in this article, but it is something that is going to come up again and again as this new model of computing (for the masses) solidifies and grows up on the Internet.

How to re-blog?
Dec 5th
I am having a crisis. Nothing earth shattering…
I read different things sent to me via multiple avenues, from email to Twitter, and then I head off to read the actual content of those shortened URLs.
But how do I get that data to other people easily without cluttering up this blog? That’s my crisis and one I am trying to figure out.
I am a geek, I read geeky thing, though not all technical and not all necessarily SFW (if you don’t know what that means…whew).
So, how to do it without cluttering up what I hope to keep a clean and informative blog…that’s the problem I need to solve.
Comments welcome!

VMware releases vSphere 4.0 Update 1
Nov 20th
The crowd cheers!
Though that might just be me :)
I am very excited for this update and I hope that it goes as smoothly as other updates have gone.
I have already updated 2 non-production systems (both ESX) and I am in the process of updating some non-production ESXi servers.
One of the items I need to schedule is the update of the vCenter software – this will require an actual outage for customers who are managing their VMs through ipHouse.
I hope that this update fixes 2 problems I have seen in the past (from the vSphere Client point of view):
- Inability for a datacenter administrator to view or clear host alerts and alarms from the hardware
- Interesting permissions issues that end up being more restrictive than the topic states
Both of these have been difficult to work around.
The first one requires the customer to contact us to ‘reset’ their hardware sensors.
The second one has actually hampered one customer from controlling their VMware cluster because of issues dealing with datastore management and the ability to attach an ISO image to their newly created VMs.
One item that is really exciting is the raising of the number of vCPUs (virtual CPUs) per physical CPU core to 25 per. Since we are able to sell VMware based virtual servers to customers, the ability to scale this higher could mean higher savings long term. Be nice to update pricing to reflect these savings later as well, though don’t know if there will be enough right now. At this point we really aren’t reaching the previous limit of 20 vCPU per pCPU.
Added support for Microsoft Windows Server 2008R2 is also welcome as we were wanting to deploy this version of Windows for customers.
Full release notes can be found here and are worth reading if you are into the enterprise products from VMware.
