Please Read The Following Carefully To Avoid Misunderstandings And Losses :
[ Please be patient while reading this content. I assure, you will not regret ]

As I told you during “Computer Fundamentals Workshop” that these are “those” Fundamentals which we Indian IT people may not know or may not understand and still pretend to deserve our degrees and jobs and salaries. That is why we are being called as “Cheap Unskilled Liar Labours”, and that is how “CANCER SPREADS”.

Similarly this “Multi-OS Installation Workshop” is not only about installing 9 Operating Systems on 1 machine but about many other things like :

01) Why : Necessity/Benefits,
02) BIOS With Respect To OS Installation,
03) EMT64/i386/x86/IA64/x64/x86_64 Terminology.
05) Boot Sector With Respect To OS Installation,
07) Partition Table,
08) MBR Partitioning Scheme,
09) GUID Partition Table (GPT) Partitioning Scheme, Supported OSs
10) Disk Cylinder/Head/Sector/LBA/LVM,
11) Partitioning Commands, Tools,
12) Capacities And Limitations Of Hard Disks,
13) Booting ( Live CD/LiveUSB )
14) Seven Boot Loaders And Ram-Disks.
15) GRUB/NLDR Tweaking, Chain-loading, Configurations And Installations,
16) File Systems And Their Identifiers,
17) Quick Format And Low Level Or “0” Level Format Of Disks,
18) Specialities Of Operating Systems With Respect To Their Order Of Installations,
19) Flavours/Distros Of Unix/Linux.
20) ACPI Tables/DSDT/SSDT/BUS Ratio,
21) System Files Of Different Operating Systems,
22) Types Of GUIs,
23) Linux And Other OS Terminology Of Disk,
24) Mounting,
25) GRUB2 Configuration,
26) Hibernation Of New Windows OS,
27) MBR/NTLDR/BootMGR/GRUB/GPT Troubleshooting Commands.
28) Virtualisation – Concepts, Types, Examples.
29) Emulator/Simulator Difference And Examples.
30) Apple Mac OS X : Macintosh/Hackintosh,

Following 9 Operating Systems will be used for installations :
[ I will tell you why I particularly chose these 9 OS ]

7 for native installation + 2 for virtual machine installation ( VirtualBox )
01) Microsoft Windows 7 – 32 Bit
02) Open Solaris – 64 Bit
03) PC-BSD – 64 Bit
04) Microsoft Windows 8.1 – 64 Bit
05) Open SuSE Linux – 64 Bit
06) Red Hat Fedora Core – 64 Bit
07) Apple Mac OS X – 64 Bit

08) Ubuntu – 64 Bit
09) Microsoft Windows 2012 Server – 64 Bit

At the end of workshop there will be DEMOS of my Multi-OS laptop and applications :
[ Few attend this workshop again-and-again just to see this ]

Rarely seen OSes :
Which are “unthinkable” for many people to have on laptop

01) MS-DOS 6.22
02) Windows 3.1
03) SCO UnixWare ( The actual PC Unix )
04) Novel Netware
05) Full featured Mac OS X without Mac

OpenGL-CUDA Demos : “Graphics Programming of Realism”
Something that IT people say “impossible” for one person to do.

* Prerequisites :
– Brain with full of whys and hows about computers.
– Mind with passion and patience of learning.
– A notebook and a pen.
– It is recommended but not must to have “Computer Fundamentals Workshop” already attended.

* Notes/CDs/DVDs :
Installation notes with few CD/DVDs will be provided to you

* What it is NOT about :
– Network Installation/Administration ( PXE Boot ) :
Topic of a separate workshop.

– Post-OS Troubleshooting :
So many troubles are there and you can not make everybody happy at all times. Although some vital tips are given in workshop.

– Laptop Installation/Troubleshooting :
Whose warranty period is still going on.
I found that Laptop service centre people complain about this.
Usually Laptop is much expensive and bought by parents’ money.

– Cloud OS/Distributed OS :
This is matter of multiple machines/nodes/clusters.

– Embedded/Mobile OS :
I have separate workshop for this, which includes
Kernel Customisation And Cross-Compile Toolchain Programming.

* Who should NOT attend :
– Those who are Syllabus/Examination/Job oriented.
– Those who are unable to sit/see/hear for long time ( I mean it ).
– Those who are unable to put their mobiles/facebook/whatsapp “SWITCHED-OFF”.
– Those who are ALWAYS busy for weekends.
– Those who are tired/bored of learning ( Really I mean it ).
– Those who are market driven rather than passion driven.
– Those who are managing “doers” rather than being one.

Special Precaution :
Workshop days may extend up to around 9-00 PM. “WOMEN SAFETY” is at utmost priority. So please reconsider in case of time and pickup constraints.

* Certificate :
A duly signed certificate of attendance of this workshop will be given.
[ I am writing this the “last”, because I want you to value it the “least” ]

I heard from many students that they get good jobs by understanding and doing Multi-OS installation on their laptops.

Dr. Vijay D Gokhale.

Javascript Automation Client

 Run method:
1) Just open the html client page in Internet Explorer.
2) Accept the warnings given by IE and click on ‘Allow blocked contents
3) Provide two sample integer values in Num1 and Num2‘s text boxes
4) Click on ‘Call COM Method’ button and Click on ‘Yes’ if prompted by browser.
5) Check the output in message boxes prompted by IE.
I have tested it on Internet Explorer 11 , Windows 8.1 x64bit and 32bit COM Automation component(same which is used for Python Client). Only limitation of Java Script client is, it runs only on Internet Explorer.

Automation Python Client(32bit) and more

I have written a python script to use our COM Component in Python. I learned basic Python syntax for our client. I have used Python 2.7.10(32bit) version on Windows 8.1(64bit). I have added the extension comtypes to Python installation which supports Python 32 bit. That’s why I had to create our 32bit Automation server component. This extension allows us to support COM components. I have tested the Python Script and working good. 🙂 Please find the attached script file.
It took 2 days to work around this and for Java script client(did not get success). I have also tried C client. It’s very good. I feel, it actually gives us a idea about how CPP’s class must be written in C(header file for C client is highly noteworthy) and also gives clear idea about virtual function table, its actual use via lpvtbl pointer.
As you said, C# does not use our IDispatch but directly calls those two methods via custom interface, I had put message boxes in the IDispatch’s functions and observed the same behavior. In case of VB client, it uses our IDispatch. In case of Python client, I observed that it is not using IDispatch but directly calls CoCreateInstance for our provided interface(here it’s IMyMath). It uses our registered type library. We can easily call QI in Python client to get desired interface pointer.

1) Download Python 2.7.10(32bit)
2) Download comtypes extension
3) comtypes documentation
4) Python Client help on codeproject

Our sessions on why Java/.NET came and now why WinRT introduced, were really good. I enjoyed them and we got the clear idea “How should we start learning a technology and How it should be taught”. Thank you.

Note: Rename PythonClient from .txt to .py

Unix System Programs

Assignment by Bhagyashree Pandit (UNIX Dec 2013 batch)

Q : Why did you do this programs?
Bhagyashree : As UNIX was in the syllabus of my last semester, Theory as well as University practical. So, sir (Dr Vijay Gokhale) told in class to refer Advanced Programming in the UNIX Environment – By W. Richard Stevens (now referred as book), as it gives the practical idea of “The Design of the UNIX Operating System by Maurice J. Bach”.
So when I start reading this book, first I solved the practical assignments with the help of this book, after that sir told me to do programs given in this book, so I started solving the same and I finished the last chapter of the book last month only.

Q : How it helped you to understand UNIX operating system ?
Bhagyashree : Well, it’s worth in many ways. First, if you know UNIX, you can understand many other operating systems since UNIX seems to be as the base (or Mother ) of most operating systems (for eg: OSX ) and secondly, many servers runs on UNIX. Also, it is fun knowing stuff most people never heard of. It can never hurt to learn as much as your interest is peaked, since I am still a student.

Most importantly you realize ‘why’ we are doing the things inside the operating system as the way we are doing. While reading operating system algorithms in Bach, it always remains back of the mind that we have to provide ‘such and such’ system call to the application programmer using which application programmer is going to write his application.

And if application programmer is to get that built in behaviour via system call then operating system has to implement it. To implement that behaviour, all this is going on. That’s how the logical chain proceeds. That means as an application programmer, I just call a fork() to create a new process. While learning allocreg, attachreg etc. I keep that in mind.
