How to learn to be a hacker easily

1) Are you sure. It is tough to be a hacker. And football players get all the attention.

2) Really? Read on

3) Read Hacker’s Code

http://muq.org/~cynbe/hackers-code.html

The Hacker’s Code

“A hacker of the Old Code.”

  • Hackers come and go, but a great hack is forever.
  • Public goods belong to the public.*
  • Software hoarding is evil.
    Software does the greatest good given to the greatest number.
  • Don’t be evil.
  • Sourceless software sucks.
  • People have rights.
    Organizations live on sufferance.
  • Governments are organizations.
  • If it is wrong when citizens do it,
    it is wrong when governments do it.
  • Information wants to be free.
    Information deserves to be free.
  • Being legal doesn’t make it right.
  • Being illegal doesn’t make it wrong.
  • Subverting tyranny is the highest duty.
  • Trust your technolust!

4) Read How to be a hacker by

Eric Steven Raymond

http://www.catb.org/~esr/faqs/hacker-howto.html

or just get the Hacker Attitude

The Hacker Attitude

1. The world is full of fascinating problems waiting to be solved.
2. No problem should ever have to be solved twice.
3. Boredom and drudgery are evil.
4. Freedom is good.
5. Attitude is no substitute for competence.
5) If you are tired of reading English, maybe I should move on to technical stuff
6) Create your hacking space, a virtual disk on your machine.
You will need to learn a bit of Linux. If you are a Windows user, I recommend creating a VMWare partition with Ubuntu
If you like Mac, I recommend the more aesthetic Linux Mint.
How to create your virtual disk-
read here-
Download VM Player here
http://www.vmware.com/support/product-support/player/
Down iso image of operating system here
http://ubuntu.com
Downloading is the longest thing in this exercise
Now just do what is written here
http://www.vmware.com/pdf/vmware_player40.pdf
or if you want to try and experiment with other ways to use Windows and Linux just read this
http://www.decisionstats.com/ways-to-use-both-windows-and-linux-together/
Moving data back and forth between your new virtual disk and your old real disk
http://www.decisionstats.com/moving-data-between-windows-and-ubuntu-vmware-partition/
7) Get Tor to hide your IP address when on internet
https://www.torproject.org/docs/tor-doc-windows.html.en
8a ) Block Ads using Ad-block plugin when surfing the internet (like 14.95 million other users)
https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/
 8b) and use Mafiafire to get elusive websites
https://addons.mozilla.org/en-US/firefox/addon/mafiaafire-redirector/
9) Get a  Bit Torrent Client at http://www.utorrent.com/
This will help you download stuff
10) Hacker Culture Alert-
This instruction is purely for sharing the culture but not the techie work of being a hacker
The website Pirate bay acts like a search engine for Bit torrents 
http://thepiratebay.se/
Visiting it is considered bad since you can get lots of music, videos, movies etc for free, without paying copyright fees.
The website 4chan is considered a meeting place to meet other hackers. The site can be visually shocking
http://boards.4chan.org/b/
You need to do atleast set up these systems, read the websites and come back in N month time for second part in this series on how to learn to be a hacker. That will be the coding part.
END OF PART  1
Updated – sorry been a bit delayed on next part. Will post soon.

Patent Wars in Mobile Software

My latest article published in India Telecom Brief on the patent wars-

 

Patent Wars in Mobile Software

Why are Apple, Microsoft and Google spending billions to acquire patents? Recently Google, maker of the largest selling mobile operating system, Android decided to acquire Motorola Mobility for 12.5 billion dollars, giving it some 17000 patents with another 7500 patents pending.
Meanwhile some months ago, a consortium led by Microsoft, Apple and Research in Motion (maker of Blackberry) bought 6000 patents by Nortel Networks for 4.5 billion dollars.
These are only the defensive moves in these patent wars. In offensive moves, Microsoft has sued HTC, Barnes and Nobles, Motorola for patent infringement over them using Android operating system claiming some aspects are patented by it. Though Google does not earn any money directly from selling Android, ironically Microsoft is earning money from Android vendors including up to 5 dollars per handset from HTC.

A brilliant infographic  from George Kokkinidis at Design Language http://news.designlanguage.com/post/1473307539 sums all the absurdity up- where almost everyone is suing everyone. Truly a picture is worth a thousand words.

 

 

 

 

Using Two Operating Systems for RATTLE, #Rstats Data Mining GUI

Using a virtual partition is slightly better than using a dual boot system. That is because you can keep the specialized operating system (usually Linux) within the main operating system (usually Windows), browse and alternate between the two operating system just using a simple command, and can utilize the advantages of both operating system.

Also you can create project specific discs for enhanced security.

In my (limited ) Mac experience, the comparisons of each operating system are-

1) Mac-  Both robust and aesthetically designed OS, the higher price and hardware-lockin for Mac remains a disadvantage. Also many stats and analytical software just wont work on the Mac

2) Windows- It is cheaper than Mac and easier to use than Linux. Also has the most compatibility with applications (usually when not crashing)

3) Linux- The lightest and most customized software in the OS class, free to use, and has many lite versions for newbies. Not compatible with mainstream corporate IT infrastructure as of 2011.

I personally use VMWare Player for creating the virtual disk (as much more convenient than the wubi.exe method)  from http://www.vmware.com/support/product-support/player/  (and downloadable from http://downloads.vmware.com/d/info/desktop_downloads/vmware_player/3_0)

That enables me to use Ubuntu on the alternative OS- keeping my Windows 7 for some Windows specific applications . For software like Rattle, the R data mining GUI , it helps to use two operating systems, in view of difficulties in GTK+.

Installing Rattle on Windows 7 is a major pain thanks to backward compatibility issues and version issues of GTK, but it installs on Ubuntu like a breeze- and it is very very convenient to switch between the two operating systems

Download Rattle from http://rattle.togaware.com/ and test it on the dual OS arrangement to see yourself.

 

 

 

 

 

How to surf anonymously on the mobile- Use Orbot

This is an interesting use case of anonymous surfing through mobile by using Tor Project on the Android Mobile OS.

Source- https://guardianproject.info/apps/orbot/
 

Orbot requires different configuration depending on the Android operating system version it is used on.

For standard Android 1.x devices (G1, MyTouch3G, Hero, Droid Eris, Cliq, Moment)

  • WEB BROWSING: You can use the Orweb Privacy Browser which we offer, which only works via Orbot and Tor.
  • For Instant Messsaging, please try Gibberbot which provides integrated, optional support for Orbot and Tor.

For Android 2.x devices: Droid, Nexus, Evo, Galaxy

  • WEB BROWSING: Non-rooted devices should use Firefox for Android with our ProxyMob Add-On to browse via the Tor network. Rooted devices can take advantage of transparent proxying (see below) and do not need an additional app installed.
  • Transparent Proxying: You must root your device in order for Orbot to work transparently for all web and DNS traffic. If you root your device, whether it is 1.x or 2.x based, Orbot will automatically, transparently proxy all web traffic on port 80 and 443 and all DNS requests. This includes the built-in Browser, Gmail, YouTube, Maps and any other application that uses standard web traffic.
  • For Instant Messsaging, please try Gibberbot which provides integrated, optional support for Orbot and Tor.

iTunes finally gets some competition ?- Amazon Cloud Player

 

An interesting development is Amazon’s Cloud Player (though Cannonical may be credited for thinking of the idea first for Ubuntu One). Since Ubuntu One is dependent on the OS (and not the browser) this makes Amazon \s version more of a  mobile Cloud Player (as it seems to be an Android app and not an app that is independent of any platform, os or browser.

Since Android and Ubuntu are both Linux flavors, I am not sure if Cannonical has an exiting mobile app for Ubuntu One. Apple’s cloud plans also seems kind of ambiguous compared to Microsoft (Azure et al)

I guess we will have to wait for a true Cloud player.

 

http://www.amazon.com/b/ref=tsm_1_tw_s_dm_liujd5?node=2658409011&tag=cloudplayer-20

How to Get Started with Cloud Drive and Cloud Player

 

Step 1. Add music to Cloud Drive

Purchase a song or album from the Amazon MP3 Store and click the Save to Amazon Cloud Drive button when your purchase is complete. Your purchase will be saved for free.

 

Step 2. Play your music in Cloud Player for Web

Click the Launch Amazon Cloud Player button to start listening to your purchase. Add more music from your library by clicking theUpload to Cloud Drive button from the Cloud Player screen. Start with 5 GB of free Cloud Drive storage. Upgrade to 20 GB with an MP3 album purchase (see details). Use Cloud Player to browse and search your library, create playlists, and download to your computer.

 

Step 3. Enjoy your music on the go with Cloud Player for Android

Install the Amazon MP3 for Android app to use Cloud Player on your Android device. Shop the full Amazon MP3 store, save your purchases to Cloud Drive, stream your Cloud Player library, and download to your device right from your Android phone or tablet.

compare this with

https://one.ubuntu.com/music/

A cloud-enabled music store

The Ubuntu One Music Store is integrated with the Ubuntu One service making it a cloud-enabled digital music store. All purchases are transferred to your Ubuntu One personal cloud for safe storage and then conveniently downloaded to your synchronizing computers. And don’t worry aboutgoing over your storage quota with music purchases. You won’t need to pay more for personal cloud storage of music purchased from the Ubuntu One Music Store.

An Ubuntu One subscription is required to purchase music from the Ubuntu One Music Store. Choose from either the free 2 GB option or the 50 GB plan for $10 (USD) per month to synchronize more of your digital life.

5 regional stores and more in the works

  • The Ubuntu One Music requires Ubuntu 10.04 LTS and offers digital music through five regional stores.
  • The US, UK, and Germany stores offer music from all major and independent labels.
  • The EU store serves most of the EU member countries (2) and offers music from fewer major label artists.
  • The World store offers only independent label music and serves the countries not covered by the other regional stores.
