Installed Eucalyptus on Ubuntu Karmic 910. Capture screenshots

I placed a lot of effort on Cloud Computing engagement and had tours around the country. Piling my mileage

First off of everthing, I demo my compiz 3D desktop enabled Ubuntu 9.04 to show off how we live in a pure open source environment without having to touch any of Microsoft.

Get back to our topic. Last week, I visited one of largest mobile device / equipment manufacturer to discuss how a Cloud Computing could transform customer’s IT. We spent an hour to talk about Return of Investment (ROI). To list what are supposed in consideration of an ROI

• Hardware
• Image Instance – build, migration, administration
• Software – non-free operating system and hypervisor. If Xen, or KVM being used on LAMP, the cost is close to zero. And all software to build a Cloud environment with licensing and maintenance.
• Labor – build and operate a Cloud environment
• Provisioning Process – time taken to complete provision

Input the above consideration comes out in 3 charts as the following (the data is under a certain assumption and might vary in different environment) :

• Comparison of without- cloud and with- cloud

• Categorized

• Cost in Transformation

The information reflects a scope of ROI to be analyzed and doesn’t have to mean this is a mandatory.

I discussed the subject with one of colleagues who is a Cloud Computing architect. I’m logging what my comment here

To continue our previous talk is a huge discussion. I’d recommend you could start to get involved in http://twitter.com and follow

http://twitter.com/mashable
http://twitter.com/j3ffyang -> me
http://twitter.com/OpenIBM -> I own this too as of being admin for IBM Open Source Global community

When you hit any of above, you can see the bytes come from http://aws.amazon.com actually, which is an IaaS with no doubt. Twitter is a kind of social collaboration network -> an application running over Amazon Web Services (AWS). Twitter doesn’t own any hardware resources. Whenever Twitter needs computing capability, it goes to AWS and AWS fulfills its request… on demand. Even though Twitter sometimes out of service due to its overload.

@ IaaS, AWS not only gives power of hardware (CPU, memory, disk and network…), but also provides plugin / API to connect Twitter with Hadoop… and Simple Queue Service (SQS), and Simple Database (SDB).

You shouldn’t be surprised @ Twitter’s power to gather thousand of thousand developers around it, if keeping our eyes open. (Some reasons of the motivation of social collaboration in term of Web2.0). See these:

This list is almost endless. They’re all independent of twitter.com. The above are all SaaS, plugable into Twitter.com where provides API -> http://apiwiki.twitter.com/ and http://twitter.com/downloads – @ PaaS

This is an ecosystem.

gedit-editor > apps > totem > buffer-size | network-buffer-threshold

Change buffer-size = 10 & network-buffer-threshold = 10

Stack: SeaMonkey 1.1.15 in Ubuntu 9.04

Symptom: Socks Proxy is set, but doesn’t work

Open SeaMoney > about:config in URL bar > type

network.proxy.type

then set the value = 2

Installed cups-pdf in Ubuntu 9.04 and changed the following in /etc/cups/cups-pdf.conf

Out ${HOME}/Desktop

Restarted /etc/init.d/cups, still received

Could not open the file /home/{you}/Desktop/273_.pdf

in /var/log/cups/error_log

The solution is, in /etc/cups/cups-pdf.conf, change to

Out ${HOME}/PDF

and create PDF directory under your home directory

Disable in gconf-editor

Or in command line:

To disable >
gconftool -s --type bool /apps/update-notifier/auto_launch false

To enable >
gconftool -s --type bool /apps/update-notifier/auto_launch true
