Red Hat Open Cloud Tour #RHCTams #conference [UPDATED]

leave a comment »

Today I spend my day at the Red Hat Open Cloud Tour, this is what happened today:

Just heard the opening by Rajiv Sodhi, who is here despite having a baby due any moment.

Margaret J. Rimmler’s keynote was interesting. One of the key takeaways being openness RedHat customers should have the choice to remain portable and replace RedHat, if that is what they want. Read the rest of this entry »

Proof of Concept: Shopper App

leave a comment »

I often get people ask me to develop phone applications based on an idea and with little other input besides the idea itself. I usually ask them to write me a proposal and send that to me, knowing that most people will procrastinate – as it turns a fun idea into work – I rarely hear anything back. Not so in this case, a friend brainstormed a shopping application and we made the following rough mock ups using OmniGraffle.

Proof of Concept: Google Docs Mail Merge Form with Text and HTML #wordpress

with one comment

I needed a way to be able to shamelessly plug the posts I recently bundled into the booklet “Write Something” again.In a similar way to the last time I did it in Proof of Concept: Google Docs Mail Merge Form

As I explained before I have set up a system to automatically mail somebody when the enter their address in the form, my issue was that I wanted to add a unique blogpost which they would only be able to get by signing up. Naturally I wanted to style it in the same way the posts are styled in this blog. Again I turned to the documentation, specifically the Class MailApp which I was using to send the mail. Using this documentation I had a starting point. I wanted three changes to the current script:

  1. keep the plain text
  2. add HTML message
  3. add inline images

Proof of Concept: Google Docs Mail Merge Form #wordpress #updated

leave a comment »

I needed a way to be able to shamelessly plug the posts I recently bundled into the booklet “Write Something“. I want to build a list, and offering something which adds value for the subscriber is a good way to do this. There is a host of good material which you can use to help, so I won’t elaborate on that in this post.

I have a hosted WordPress.com blog, which means that I can’t run a local script to collect the mail addresses and mail them, so I turned to Google Docs’ Form functionality for the entry form, naturally I give them the option to download the booklet there, and I wanted to send the subscriber a message to thank them. In the Google tutorial: Simple Mail Merge they explain how to do a mail merge using the Script Editor. I wanted to go a little further and have it send a mail with thank you note and a link to each subscriber as soon as they filled in the form.

On the Border of the Internet #risk

with 3 comments

The age old lie told by ISP support desks: ” The Internet is down,” was briefly reality again yesterday.

The past couple of days I’d been seeing and hearing comments that there was a disturbance in the force of the Internet. Initially a NANOG message was posted about a general malaise or instability in the Internet, some humorous quips were posted in response and the matter was soon forgotten.

A network operator looking with hindsight said that they had been able to see more than normal numbers of updates coming on BGP which is normally an indicator of network instability being solved by rerouting round the problem. That is all part of the normal operation of the Internet. And sometime yesterday morning as the east coast of the US was getting to work the looming disaster struck.

Juniper network devices started core dumping and restarting due to a bug in the code which handled the BGP UPDATE messages as another large updated was arriving. The self healing properties of the Internet broke and the Internet went with it. The Great Juniper Outage of 2011 was born.

Avoidable?

Almost certainly. The reliance on the hardware of one specific vendor on the part of large ISPs – backbone carriers – creates a single point of failure which is bad – mkay. A fail over situation should always be in place, not just at the ISPs. Companies who rely on the Internet for business should take this into account too. A recent outages at some of companies I consulted said that by placing their faith in one specific vendor they had created a single point of failure which had caused some high profile repercussions.

Do you have a single point of failure?

AI Class #school #education #stanford

leave a comment »

Stanford’s AI Class has started and am finding it easy and enjoying it. I’m sure that like any other class it will soon become more challenging, and more interesting. I have a similar feeling to when I followed the Game Theory Lectures by Benjamin Polak from Yale.

I will continue to post updates here.
