Decisionstats.com is back from a dDOS

  1. Servers were okay, it was the DNS server that got swamped.
  2. I am sorry for the downtime- hopefully you didnt even notice
  3. I have faced challenges like domain name hijacking, sql injection , malicious WP plugins and thats why shifted to a professional hosting. I stand by my vendors and their professional judgement, moving away would mean the hackers won.
  4. This was very clever to swamp the DNS provider- my compliments to the tech talent behind this.
  5. You would think that every webmaster would have a back up plan in case his site went dDOS, but surprisingly even corporate websites dont have a back up (under attack) plan

Including juicy stuff on using a cluster of Apple Machines for grid computing , seasonality forecasting (Yet Another Package For Time Series )

But I kind of liked Sumo too-

https://code.google.com/p/sumo/

Sumo is a fully-functional web application template that exposes an authenticated user’s R session within java server pages.

Sumo: An Authenticating Web Application with an Embedded R Session by Timothy T. Bergsma and Michael S. Smith Abstract Sumo is a web application intended as a template for developers. It is distributed as a Java ‘war’ file that deploys automatically when placed in a Servlet container’s ‘webapps’
directory. If a user supplies proper credentials, Sumo creates a session-specific Secure Shell connection to the host and a user-specific R session over that connection. Developers may write dynamic server pages that make use of the persistent R session and user-specific file space.

and for Apple fanboys-

We created the xgrid package (Horton and Anoke, 2012) to provide a simple interface to this distributed computing system. The package facilitates use of an Apple Xgrid for distributed processing of a simulation with many independent repetitions, by simplifying job submission (or grid stuffing) and collation of results. It provides a relatively thin but useful layer between R and Apple’s ‘xgrid’ shell command, where the user constructs input scripts to be run remotely. A similar set of routines, optimized for parallel estimation of JAGS (just another Gibbs sampler) models is available within the runjags package (Denwood, 2010). However, with the exception of runjags, none of the previously mentioned packages support parallel computation over an Apple Xgrid.

Hmm I guess parallel computing enabled by Wifi on mobile phones would be awesome too ! So would be anything using iOS . See the rest of the R Journal at http://journal.r-project.org/current.html

The economics of software piracy

Software piracy exists because-

1) Lack of appropriate technological controls (like those on DVDs) or on Bit Torrents (an innovation on the centralized server like Napster) or on Streaming etc etc.

Technology to share content has evolved at a much higher pace than technology to restrict content from being shared or limited to purchasers.

2) Huge difference in purchasing power across the globe.

An Itunes song at 99 cents might be okay buy in USA, but in Asia it is very expensive. Maybe if content creators use Purchasing Power Parity to price their goods, it might make an indent.

3) State sponsored intellectual theft as another form of economic warfare- this has been going on since the West stole gunpowder and silk from the Chinese, and Intel decided to win back the IP rights to the microprocessor (from the Japanese client)

4) Lack of consensus in policy makers across the globe on who gets hurt from IP theft, but complete consensus across young people in the globe that they are doing the right thing by downloading stuff for free.

5) There is no such thing as a free lunch. Sometimes software (and movie and songs) piracy help create demand across ignored markets – I always think the NFL can be huge in India if they market it.Sometimes it forces artists to commit suicide because they give up on the life of starving musician.

Mostly piracy has helped break profits of intermediaries between the actual creator and actual consumer.

So how to solve software piracy , assuming it is something that can be solved-

I dont know, but I do care.

I give most of my writings as CC-by-SA and that includes my poems. People (friends and family) sometimes pay me not to sing.

Pirates have existed and will exist as long as civilized men romanticize the notion of piracy and bicker between themselves for narrow gains.

  1. Ephesians 4:28 Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need.
  2. A clean confession, combined with a promise never to commit the sin again, when offered before one who has the right to receive it, is the purest type of repentance.-Gandhi
  3. If you steal, I will wash your mouth with soap- Anonymous Mother.
  4. You shall not steal- Moses
  5. Steal may refer to: Theft, the illegal taking of another person’s property without that person’s freely-given consent; The gaining of a stolen base in baseball;
