How big is R on CRAN #rstats
3.87 GB and 3786 packages. Thats what you need to install the whole of R as on CRAN
( Note- Many IT administrators /Compliance Policies in enterprises forbid installing from the Internet in work offices.
Which is where the analytics,$$, and people are)
As downloaded from the CRAN Mirror at UCLA.
Takes 3 hours to download at 1 mbps (I was on an Amazon Ec2 instance)
See screenshot.
Next question- who is the man responsible in the R project for deleting old /depreciated/redundant packages if the authors dont do it.
Visualizing Bigger Data in R using Tabplot
The amazing tabplot package creates the tableplot feature for visualizing huge chunks of data. This is a great example of creative data visualization that is resource lite and extremely fast in a first look at the data. (note- The tabplot package is being used and table plot function is being used . The TABLEPLOT package is different and is NOT being used here).
library(ggplot2)
data(diamonds)
library(tabplot)
tableplot(diamonds)
system.time(tableplot(diamonds))
visualizing a 50000 row by 10 variable dataset in 0.7 s is fast !!
click on screenshot to see it
and some say R is slow
Note I used a free Windows Amazon EC2 Instance for it-
See screenshot for hardware configuration
the best thing is there is a handy GTK GUI for this package. You can check it out at
Using Cloud Computing for Hacking
This is not about hacking the cloud. Instead this is about using the cloud to hack
Some articles last year wrote on how hackers used Amazon Ec2 for hacking/ddos attacks.
Roth claims that a typical wireless password can be guessed by EC2 and his software in about six minutes. He proved this by hacking networks in the area where he lives. The type of EC2 computers used in the attack costs 28 cents per minute, so $1.68 is all it could take to lay open a wireless network.

Cloud services are also attractive for hackers because the use of multiple servers can facilitate tasks such as cracking passwords, said Ray Valdes, an analyst at Gartner Inc. Amazon could improve measures to weed out bogus accounts, he said.
and this article by Anti-Sec pointed out how one can obtain a debit card anonymously

VPN Account without paper trail
- Purchase prepaid visa card with cash
- Purchase Bitcoins with Money Order
- Donate Bitcoins to different account
Masking your IP address to log on is done by TOR

and the actual flooding is done by tools like LOIC or HOIC

So what safeguards can be expected from the next wave of Teenage Mutant Ninjas..?
Amazon CC2 – The Big Cloud is finally here
Finally a powerful enough cloud computing instance from Amazon EC2 – called CC2 priced at 3$ per hour (for Windows instances) and 2.4$/hour for Linux
It would be interesting to see how SAS, IBM SPSS or R can leverage these
Storage - On the storage front, the CC2 instance type is packed with 60.5 GB of RAM and 3.37 TB of instance storage.
Processing - The CC2 instance type includes 2 Intel Xeon processors, each with 8 hardware cores. We’ve enabled Hyper-Threading, allowing each core to process a pair of instruction streams in parallel. Net-net, there are 32 hardware execution threads and you can expect 88 EC2 Compute Units (ECU’s) from this 64-bit instance type
On a somewhat smaller scale, you can launch your own array of 290 CC2 instances and create a Top500 supercomputer (63.7 teraFLOPS) at a cost of less than $1000 per hour
and

Cluster Compute Eight Extra Large specifications:
88 EC2 Compute Units (Eight-core 2 x Intel Xeon)
60.5 GB of memory
3370 GB of instance storage
64-bit platform
I/O Performance: Very High (10 Gigabit Ethernet)
API name: cc2.8xlarge
Price: Starting from $2.40 per hour
But some caveats
- The instances are available in a single Availability Zone in the US East (Northern Virginia) Region. We plan to add capacity in other EC2 Regions throughout 2012.
- You can run 2 CC2 instances by default.
- You cannot currently launch instances of this type within a Virtual Private Cloud (VPC).
Interview Markus Schmidberger ,Cloudnumbers.com
Here is an interview with Markus Schmidberger, Senior Community Manager for cloudnumbers.com. Cloudnumbers.com is the exciting new cloud startup for scientific computing. It basically enables transition to a R and other platforms in the cloud and makes it very easy and secure from the traditional desktop/server model of operation.
Ajay- Describe the startup story for setting up Cloudnumbers.com
Markus- In 2010 the company founders Erik Muttersbach (TU München), Markus Fensterer (TU München) and Moritz v. Petersdorff-Campen (WHU Vallendar) started with the development of the cloud computing environment. (more…)
Cloud Computing by Windows , Amazon and Google for free
Some ways to test and use cloud computing for free for yourself-
- Windows Azure
- Amazon Ec2
- Google Storage
The folks at Microsoft Azure announced a 90 day free trial (more…)
