R in Oracle Java Cloud and Existing R – Java Integration #rstats

So I finally got my test plan accepted for a 1 month trial to the Oracle Public Cloud at https://cloud.oracle.com/ .

oc1 I am testing this for my next book R for Cloud Computing ( I have already covered Windows Azure, Amazon AWS, and in the middle of testing Google Compute).

Some initial thoughts- this Java cloud seemed more suitable for web apps, than for data science ( but I have to spend much more time on this).

I really liked the help and documentation and tutorials, Oracle has invested a lot in it to make it friendly to enterprise users.

Hopefully the Oracle R Enterprise  ORE guys can talk to the Oracle Cloud department and get some common use case projects going.

In the meantime, I did a roundup on all R -Java projects.

They include- Continue reading “R in Oracle Java Cloud and Existing R – Java Integration #rstats”

Can Microsoft buy Facebook

At $39.23 Billion , Facebook is now cheaper than what Steve Ballmer was prepared to pay for Yahoo (when Yahoo CEO Jerry Yang famously turned him down). Can Microsoft buy Facebook? or Can Apple buy Facebook?

Both would be okay from an anti trust perspective- and both have the cash. Note you need only to buy 51% of shares for controlling and Mark Zuckerberg seems a bit down (never mind Sean Parker’s voting arrangement).

Can Google plunk 20% of FB for 8 billion – less than they paid for Motorola, so they can sell Ads there while FB concentrates on thee social aspects.

FB has innovated with good UI, apps, cassandra,the like button, the FB connect network, and of course socially targeted ads. I dont think it’s stock price deserves to be dog with fleas.

Where is a good leveraged buy out (LBO) or hedge fund when you need one?

But, Seriously.

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

Secure Browsing from Mobile and PC ( Tor ,PeerNet, WasteAgain)

While Tor remains the tool of choice with pseudo-techie hacker wannabes , there is enough juice and smoke and mirrors on the market to confuse your average Joe.

For a secure browsing experience on Mobile – do NOT use either Apple or Windows OS

Use Android  and this app called Orbot in particular

Installing Tor with a QR code

Orbot is easy to install by simply scanning the following QR code with your Android Barcode scanner.

Android QR code

Installing Tor from the Android Market

Orbot is available in the Android Market.

ENTER PEERNET

If you have a Dell PC, well just use PeerNet to configure and set up your own network around the neighbourhood. This is particularly applicable if you are in country that is both repressive and not so technologically advanced. Wont work in China or USA.

http://support.dell.com/support/edocs/network/p70008/EN/vista_7/peernet.htm

What is a peer network?

A peer network is a network in which one computer can connect directly to another computer. This capability is accomplished by enabling access point (AP) functionality on one of the computers. Other computers can then connect to this computer in the same way that they would connect to a physical AP. If Internet Connection Sharing is enabled on the computer that has the AP functionality, computers that connect to that computer have Internet connectivity as well.

A basic peer network, which requires no networking knowledge or experience to set up, should meet the needs of most home users and small businesses. By default, a basic peer network is configured with the strongest available security (see How do I set up a basic peer network?).

For users who are familiar with wireless networking technology, advanced configuration features are available to do the following:

Change security settings (see How do I configure my peer network?)
Choose which method (push button or PIN) computers with Wi-Fi Protected Setup™ capability can join your peer network (see How do I allow peer devices to join my peer network using Wi-Fi Protected Setup technology?)
Change the DHCP Server IP address (see How do I configure my peer network?).
Change the channel on which to operate your peer network (see How do I configure my peer network?)

 If you are really really in a need for secure browsing (like you are maybe a big hot shot in the tech world), I suggest go over to VMWare

http://www.vmware.com/products/player/

create a seperate Linux (Ubuntu for ease) virtual disc, then download the Tor Browser Bundle from

https://www.torproject.org/projects/torbrowser.html.en for surfing and a Peernet (above) or  a prepaid one time use disposable mobile pre-paid wireless card. It is also quite easy to delete your virtual disc in times of emergencies (but it is best to use encryption even when in Ubuntu https://help.ubuntu.com/community/EncryptedHome)

IRC chat is less secure than you think it is thanks to BOT  Trawlers- so I am hoping someone in the open source community updates Waste Again for encrypted chats http://wasteagain.sourceforge.net/

What is “WASTE again”?

“WASTE again” enables you to create a decentralized and secure private mesh network using an unsecure network, such as the internet. Once the public encryption keys are exchanged, sending messages, creating groupchats and transferring files is easy and secure.

Creating a mesh

To create a mesh you need at least two computers with “WASTE again” installed. During installation, a unique pair of public and private keys for each computer is being generated. Before the first connection can be established, you need to exchange these public keys. These keys enable “WASTE again” to authenticate every connection to other “WASTE again” clients.

After exchanging the keys, you simply type in the computers IP address to connect to. If that computer is located behind a firewall or a NAT-router, you have to create a portmap first to enable incoming connections.

At least one computer in your mesh has to be able to accept incoming connections, making it a “public node”. If no direct connection between two firewalled computers can be made, “WASTE again” automatically routes your traffic through one or more of the available public nodes.

Every new node simply has to exchange keys with one of the connected nodes and then connect to it. All the other nodes will exchange their keys automatically over the mesh.

A Brief Overview of Open vs Closed in Computing

2008- Apple (Closed Hardware and Software) vs Google (Android/Linux) -(Free and Open Source)

2010 – Google (Web open to search) vs Facebook (Closed to search)

2018 (?)-Google (Code is open for all non revenue generating software, but search engine algorithm is closed) VS       TBD

10 Ways We will miss Steve Jobs

I am not an Apple fanboy.In fact I dont use a Mac (because Linux works well for me at much cheaper rates)

I am going to miss Steve Jobs like I miss …… still.

1) The Original Pirate – I liked Steve Jobs ever since I saw Pirates of Silicon Valley, I wanted to be like the Jobs who created jobs http://en.wikipedia.org/wiki/Pirates_of_Silicon_Valley

Artists steal. Yeah baby!

2) Music -Itunes Improbably the man who came up with the idea of music @ 99 cents helped more artists earn money in the era of Napster. Music piracy is not dead, but at 99 cents you CAN afford the songs

3) Aesthetics- and Design- as competitive barriers. It was all about the interface. People care about interfaces. Shoody software wont sell.

4) Portable Music- yes I once wrote a poem on my first Ipod. http://www.decisionstats.com/ode-to-an-ipod/ No , it doesnot rank as the top ten poems on Ipod in SERP

Walkman ‘s evolution was the Ipod – and it was everywhere.

5) Big Phones can be cool too- I loved my IPhone and so did everyone. But thats because making cool phones before that was all about making the tiniest thinnest phone. Using Videochat on Iphone and webs surfing were way much cooler than anything before or since.

6) Apps for Money for Geeks. Yes the Apps marketplace was more enriching to the geek universe than all open source put together.

7) Turtleneck Steve- You know when Steve Jobs was about to make a presentation because one week before and one week later the whole tech media behaved like either a fanboy or we are too cool to be an Apple fanboy but we will report it still. The man who wrote no code sold more technology than everyone else using just a turtleneck and presentations.

8) Pixar toons- Yes Pixar toons made sure cartoons were pieces of art and not just funny stuff anymore. This one makes me choke up

9) Kicking Microsoft butt- Who else but Steve can borrow money from MS and then beat it in every product it wanted to.

10) Not being evil. Steve Jobs made more money for more geeks than anyone. and he made it look good! The original DONT BE EVIL guy who never needed to say it aloud

Take a bow Steve Jobs (or touch the first Apple product that comes to your hand after reading this!)

The article was first written on Aug 25,2011 on Steve Jobs resignation news.It has been updated to note his departing from this planet as of yesterday.
