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.

Amazon gives away 750 hours /month of Windows based computing

and an additional 750 hours /month of Linux based computing. The windows instance is really quite easy for users to start getting the hang of cloud computing. and it is quite useful for people to tinker around, given Google’s retail cloud offerings are taking so long to hit the market

But it is only for new users.

http://aws.typepad.com/aws/2012/01/aws-free-usage-tier-now-includes-microsoft-windows-on-ec2.html

WS Free Usage Tier now Includes Microsoft Windows on EC2

The AWS Free Usage Tier now allows you to run Microsoft Windows Server 2008 R2 on an EC2 t1.micro instance for up to 750 hours per month. This benefit is open to new AWS customers and to those who are already participating in the Free Usage Tier, and is available in all AWS Regions with the exception of GovCloud. This is an easy way for Windows users to start learning about and enjoying the benefits of cloud computing with AWS.

The micro instances provide a small amount of consistent processing power and the ability to burst to a higher level of usage from time to time. You can use this instance to learn about Amazon EC2, support a development and test environment, build an AWS application, or host a web site (or all of the above). We’ve fine-tuned the micro instances to make them even better at running Microsoft Windows Server.

You can launch your instance from the AWS Management Console:

We have lots of helpful resources to get you started:

Along with 750 instance hours of Windows Server 2008 R2 per month, the Free Usage Tier also provides another 750 instance hours to run Linux (also on a t1.micro), Elastic Load Balancer time and bandwidth, Elastic Block Storage, Amazon S3 Storage, and SimpleDB storage, a bunch of Simple Queue Service and Simple Notification Service requests, and some CloudWatch metrics and alarms (see the AWS Free Usage Tier page for details). We’ve also boosted the amount of EBS storage space offered in the Free Usage Tier to 30GB, and we’ve doubled the I/O requests in the Free Usage Tier, to 2 million.

 

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

1984 – IBM   (Big Brother) vs Apple  (Computing opened for individuals)

1988- Apple (Closed Hardware and Software) vs Microsoft (  Licensed to all software)

1998- Microsoft (Source code is closed but licenses to all) vs Linux (Open Source Code)

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

Moving data between Windows and Ubuntu VMWare partition

I use Windows 7 on my laptop (it came pre-installed) and Ubuntu using the VMWare Player. What are the advantages of using VM Player instead of creating a dual-boot system? Well I can quickly shift from Ubuntu to Windows and bakc again without restarting my computer everytime. Using this approach allows me to utilize software that run only on Windows and run software like Rattle, the R data mining GUI, that are much easier installed on Linux.

However if your statistical software is on your Virtual Disk , and your data is on your Windows disk, you need a way to move data from Windows to Ubuntu.

The solution to this as per Ubuntu forums is –http://communities.vmware.com/thread/55242

Open My Computer, browse to the folder you want to share.  Right-click on the folder, select Properties.  Sharing tab.  Select the radio button to “Share this Folder”.  Change the default generated name if you wish; add a description if you wish.  Click the Permissions button to modify the security settings of what users can read/write to the share.

On the Linux side, it depends on the distro, the shell, and the window manager.

Well Ubuntu makes it really easy to configure the Linux steps to move data within Windows and Linux partitions.

 

NEW UPDATE-

VMmare makes it easy to share between your Windows (host) and Linux (guest) OS

 

Step 1

and step 2

Do this

 

and

Start the Wizard

when you finish the wizard and share a drive or folder- hey where do I see my shared ones-

 

see this folder in Linux- /mnt/hgfs (bingo!)

Hacker HW – Make this folder //mnt/hgfs a shortcut in Places your Ubuntu startup

Hacker Hw 2-

Upload using an anon email your VM dark data to Ubuntu one

Delete VM

Purge using software XX

Reinstall VM and bring back backup

 

Note time to do this

 

 

 

-General Sharing in Windows

 

 

Just open the Network tab in Ubuntu- see screenshots below-

Windows will now ask your Ubuntu user for login-

Once Logged in Windows from within Ubuntu Vmware, this is what happens

You see a tab called “users on “windows username”- pc appear on your Ubuntu Desktop  (see top right of the screenshot)

If you double click it- you see your windows path

You can now just click and drag data between your windows and linux partitions , just the way you do it in Windows .

So based on this- if you want to build  decision trees, artifical neural networks, regression models, and even time series models for zero capital expenditure- you can use both Ubuntu/R without compromising on your IT policy of Windows only in your organization (there is a shortage of Ubuntu trained IT administrators in the enterprise world)

Revised Installation Procedure for utilizing both Ubuntu /R/Rattle data mining on your Windows PC.

Using VMWare to build a free data mining system in R, as well as isolate your analytics system (thus using both Linux and Windows without overburdening your machine)

First Time

  1. http://downloads.vmware.com/d/info/desktop_end_user_computing/vmware_player/4_0Download and Install
  2. http://www.ubuntu.com/download/ubuntu/downloadDownload Only
  3. Create New Virtual Image in VM Ware Player
  4. Applications—–Terminal——sudo apt get-install R (to download and install)
  5.                                          sudo R (to open R)
  6. Once R is opened type this  —-install.packages(rattle)—– This will install rattle
  7. library(rattle) will load Rattle—–
  8. rattle() will open the GUI—-
Getting Data from Host to Guest VM
Next Time
  1. Go to VM Player
  2. Open the VM
  3. sudo R in terminal to bring up R
  4. library(rattle) within R
  5. rattle()
At this point even if you dont know any Linux and dont know any R, you can create data mining models using the Rattle GUI (and time series model using E pack in the R Commander GUI) – What can Rattle do in data mining? See this slideshow-http://www.decisionstats.com/data-mining-with-r-gui-rattle-rstats/
If Google Docs is banned as per your enterprise organizational IT policy of having Windows Explorer only- well you can see these screenshots http://rattle.togaware.com/rattle-screenshots.html

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.

 

 

 

 

Open Source Analytics

My guest blog at Allanalytics.com is now up

http://www.allanalytics.com/ is the exciting community which looks at the business aspects to the analytics market with a great lineup of pedigree writers.

It is basically a point/counterpoint for and against open source analytics. I feel there is a scope of lot of improvement before open source dominates the world of analytics software like Android, Linux Web Server do in their markets. Part of this reason is – there needs to be more , much more investment in analytics research, development, easier to use interfaces, Big Data integration and rewarding ALL the writers of code regardless of whether the code is proprietary or open source.

A last word- I think open source analytics AND proprietary analytics software will have to learn to live with one another, with game theory dictating their response and counter-response. More competition is good, and open source is an AND option not an OR option to existing status quo.

You can read the full blog discussion at http://www.allanalytics.com/author.asp?section_id=1408&doc_id=233454&piddl_msgorder=thrd#msgs

Hopefully discussion would be more analytical than passionate 🙂 and greater investments in made in analytics by all sides.
