My first love with Entrepreneurship

Posted in Business, General tagged , , , at 11:51 am by asprakash

It is not so pain. But ofcourse, pain is the pain. Here I would like to share my thoughts and feelings about the term “Entrepreneurship” and obviously how is my entrepreneurship life is going on.

What is Entrepreneurship

Well, I am not going to explain about it here. Please refer this nice wikipage here. But from my point of view apart from the business and money, the entrepreneurship is one who creates the future for others. In detail, he/she creates good career & job opportunity for people belongs to him, he/she creates economic growth for a country, technology promotions,.etc.

My entrepreneurship life

My star-up is I have just less than 6 months experience in my entrepreneurship life.  But I already invested around 2 years of my time to my start-up company. There were so many +ve and -ve suggestions got from my well wishers/friends/parents/ when I planed to start-up my own company. My friends advised me to join a MNC and earn money first and then start-up a company. My parents much worried about my horoscope(?)! and so many etc etc suggestions. Ofcourse, few of them encouraged me to go ahead. Some of the over confidence suggestions are, “If you cant, then who will”… ;).

I have my own dreams; my own ambitions and targets. Now planing to achieve my target and take my steps one by one confidently and carefully. Till now, many steps already taken and those steps finished in failure. The terms “failure” is not an word to hate in our life. But it must be observed by everybody; Know our failures and correct it later. So that a person can able to achieve an target. Nobody in this world directly  jump to the target in a single step/try. Step by step progress is always safer and provides more experience to avoid failure in future.

Somebody said, now I am a Business man. Business and Entrepreneurship differs from some other way. A independent person can do business and earn money. For example, running a shop, hotel,.etc. However, Entrepreneur is also doing business. But he creates career for others and he is used to invest the earning money into new business opportunity and so on.

If you are working in Infosys, Micrsoft, CTS, TCS,.etc and earning few laks per annum, do you think when your company founded, it was started from a big Tidel park in a central heart city? Do you think, your company CEO, early met your clients traveling by flight? Do you think, when your company founded, the employee’s strenght was around 10,000? Do you think, when your company founded, all the employees got nice salary like you?. There are so many good MNC companies (HCL, Infosys,.etc)started from an single room and they used bike to met their clients.

I am also in the same position to preparing the strong foundation and providing best career opportunity for my employees in future.

There are around 2998 engineering colleges are available in India and ~5 laks  fresh engineers (I did not calculated other degree holders. If so, then the numbers will be more per year!)are come-out every year. Practically, It is not possible to provide the job opportunity for all the engineers by those CTC,TCS,Infosys,.etc companies. And if everybody wants to work with a company, then who will create the job opportunity?. As my favorite  Dr.Abdul Kalam said, “Indian engineers wants to create the job opportunity instead of like to work with someone”. Due to lack of support for new entrepreneurs, from friends, home, relations, Governments and Government policies  I am not sure, when it will happened and how it will happened.

Output of Entrepreneurship

Once I started my own company, many of my well wishers now expected some output from me. I am not sure, what they are mean by “Output”. They are thinking like, once we started our own company, then we can immediately earn Crores & Crores. It is so funny!. If this is true and easy, then why the people are want to join with a company and why they should not start-up their own?. And few others thinking like, once we open a company ( like shop?), then we can start earning money automatically. Obviously, running a enterprise is not like an shop/store and earn 2 times of money at evening when we invested some money at morning. We need to put more efforts, hardwork and most important one is patient. Finally the endurance. I guess, it will take to earn money by an start-up company minimum upto first 6 months and based on the services/products.

As per my concern, running a enterprise at this economic down situation, we need to put infinite hardwork, patient, endurance, time, confidence and obviously money. There is no use of starting a company with missing of any one from the above.

My entrepreneurship experience and suggestions for young entrepreneurs

  • Rest :: Now a days my sleeping time is less than 6 hours. I guess, it will decreased more in future. But maintain your sleeping hours atleast 6.
  • Time & Friends :: Not possible to spend time for chat with friends, movies, outing, roaming,.etc. Need to avoid these activities. If you feel, you cant ignore anybody, then talk with your friends and explain about it. They will understand you.
  • Time & Girl friends :: One of the main reason, why the guys are wasting their time is, girl friends!. You must keep it in mind that, your time is so valuable. Do not waste much time with girl friends through by Phone, Chat, roaming,.etc. WARNING!. You are very near to the door, “Failure”.
  • Depression :: You will get more depression these days. Bcoz most people will reject you : customers, investors, employees you try to hire, organizers of startup showcases. You have to keep looking for the ones who will accept you.
  • Failure :: Dont bother about the failure and dont afraid. Learn the failure and accept the failure. If you failed 20 times; 50 times; 100 times. Try again & again. One day “failure” will get bored and run away!.
  • Time & Relatives:: Do not waste much time to visit your relatives home, relatives functions,.etc. Convey your regards over by phone. Any important functions, you may consider. It may helpful for you to refresh yourself.
  • Bankers :: You will be rejected to get an Credit card, account from an Bank,.etc. Dont worry. They will comeback to you surely, later.
  • Advise :: You will get more advise from your relatives to search a good job and earn money. So that you will get a good alliance. Do not consider this kind of advice. Once you succeeded, then they will tell you, “Yes, I know on the first day itself, you will become a millionaire”.
  • Employee’s risk :: Retaining employees is an crucial task. Its upto you, how you are going to handle. You may consider like, offering employee benefits, bonds, salary hike,.etc.
  • No Holidays! :: You dont want any holidays these days. Either work from your room/home or from office. Having a USB data card will help you to work with internet at any time from any where.
  • Quick response :: You must provide proper response to your customers and every one of your customer is highest priority to you.
  • Finally, absorb all your pain; learn it; try it again and again. Success is very near to you.

Last but not least, Do not forgot that, you are not going to build your career; But you are also going to build  the entire career for thousands of your future employees. I wish you all the best. Here I would like to share a poet.

தெய்வத்தால் ஆகாதெனினும் முயற்சி தன்
மெய்வருத்த கூலி தரும்.

Meaning of the above poet :: Suppose the god cant help you in certain case; But your hardwork will help you to get the credits.

How developers/companies are earning money from Open Source environment?

Posted in Entrepreneurship, General, Open Source tagged , , at 4:05 am by asprakash

A Free and Open Source Software (FOSS) need not a free of cost. We can earn money in some ways from Open Source softwares by directly and indirectly.

* Hope you know, we dont have any official supports for Open Source softwares. Take a OS s/w; Sale it with free of cost for your customer. When they want support, you just charge some money.
* One important drawback in OS is, no ready made development environment and taking more time duration for setting up a environment. if you will do every thing in a single package, then you can earn more money from OS. For example, still we dont have any ready made working environment for embedded linux. We have to install more tools and need to configure lot of things. Its an nightmare for developers. If you possible to collect all the tools, configure it and ready for sale, you can earn more money, I m sure.
* You can also earn money by teaching OS tools and softwares, like provide training.
* You can also earn money by providing installation setup/supports for an company/organizations. CDAC is d example in this case. They are doing this business for all the government org from BOSS linux.
* My-sql is an open source DB. Recently, Mr.Brain [Owner of mq-sql]sale his OS project MY-AQL to another company for some millions. But it took around 6 years for earn this money from his open source project.
* Sale a OS operating system CD/DVD is an good business and more…

Why the companies are starting a OS software

You may ask this question, definitely. Now we can see why a company/developer start an OS project.
* You will get more contributions from community. So that your product will be stable soon.
* Get more contribution from community. You no need to recruit more people for this project.
* Google encourage more OS activities like Google SOC and this is the best example company for earning more money from OS by directly and indirectly.
* Intel have a big OS community. So that they are getting contributions for writing drivers for their processors. They have lots of other OS projects too,
* NOKIA, have a OS community. Initially they started with couple of OS projects. Now they have more than 25 projects in a short period. Through this OS activity, they are getting more contributions for their application development and others. visit
* {After NOVELL earned more bad issues from communities, once tied with Microsoft} Now AMD supports OpenSUSE project,
* nVidia have a OS community and they are getting more contributions for writing drivers for their devices.
* There are lots of companies are having OS activities. Coz, they are getting credits indirectly, compare with what they are earning money by directly.

Howto get a embedded system job and what i want to do for that.

Posted in Embedded System, General tagged , , , at 10:20 am by asprakash

I think recently I am getting more queries related this topic.
I would like to share my suggestions with all the freshers in embedded system. We have already discussed about it. But still the freshers are not getting any clear idea about, howto get a job in embedded system. Hope this thread will helpful for them to understand first, what the industries are expecting from them. I request you to post all your comments here, if you have any. Please also note that, the given points are only my personal suggestion; There is no intention to force you to take any decision based on my inputs.

Dont do/think

* Entry for freshers in embedded system is really easy…
* I will get a job immediately, coz I have an embedded system certification from the great -ABC- institution.
* I have fully fitted for embedded system field. Coz I have completed all the modules including, C,C++,Unix, Device drivers, Micro controllers and RTOS. Oh….I am great. What do you want more…. 😀
* If I cant get any job in this field, then I can just put an 1+ yr fake experience and apply for job. The recruiter will accept my CV. Then I will get a job easily. Oh…I am really so brilliant…. 😀
* If I add one or two projects [especially some rtos projects like vxworks ]in my resume then i can easily get an job.
* I have 80% marks in all the certificates. The interviewer will accept me for this embedded system field.
* I have done a embedded system project in a big MNC embedded systems company. So i am eligible for getting a job.

Then What I want to do/Think?

* Whatever it may be, You should learn from in-depth. For hardware engineers, learn from flipflop, micro processor….etc. For software engineers, learn from compilers, linkers, OS concepts….etc.
* Do some real time projects from what you have learnt. For example, you have 6 modules in a course, try to do minimum one project for each module by your own and the project should be related with industries use or from latest technologies.
* Try to utilize your lab facilities. Especially your lab hardwares. Hack it, whatever you want. Or how much you are ready to spend for fun. Try to buy one cheap embedded development board. You can surely learn a lot from it.
* Learn the Linux OS for embedded system. Coz it has good future in embedded system and in India. Moreover,  Linux is exactly suitable for embedded system field rather than the M$ windows. Another reason is, you can hack the linux from top to bottom. Bcoz its open source and no need to depending on any proprietary softwares. So that you can learn more and get more real time experience.
* Plan to buy a hardware board like ARM 7/9/11/Cortex (if you are planing to learn OS level embedded systems) or Microcontroller boards like Arduino. You can get the hardware from Rs.2000/- to Rs.10,000 based on the configuration. Using this boards, you can feel the real time experience for porting, cross compilation, linux, emb linux, rtlinux and other rtos. If you got will these experience, you can surely cross the technical interview.
* You should sharp your language skills like C,C++,Java….etc. Language is very important for s/w embedded system engineers.
* Try to contribute to some international forums, mailing lists and magazines like, So that you can update your knowledge in this field and really understand whats happening in the current embedded field on industries side.
* Try to contribute some embedded system open source projects already available in internet. Go through the site, and search for embedded system project. you will get thousands of project related embedded system. Definitely, you will get nice experience on this field. Beagleboard, Pandaboard, Arduino,.etc are some of the widely used embedded open source boards.

What are the available chances for getting a job in this field

(1) Select an embedded system company in your college placements. Avoid the s/w companies like CTS, Infosys…etc, if you have a confident to get a job in embedded field/company.
(2) If you dont have the placements, send your resumes for selected embedded system companies, even you are an fresher. Insist your full of interest in embedded system along with an covering letter. DO NOT SEND YOUR CV AS AN JUNG/SPAM OR “CC” TO ALL THE COMPANIES. ITS AN BAD ATTITUDE.
(3) After 6 months you got finished your degree, you may join with some embedded system course. During this 6 months, you can try for freshers job. You may get some placements through your training institute. But this is not guarantee. Its depends the institution and your capability. Howevr, the course is not necessary for embedded system, if you have capable to learn by your own with full of self confident. My personal opinion is, I wont suggest you to do a course. Coz, in India most of the institutions are not teaching good in embedded systems. They are only targeting on you money. Or cross check the institutions capability and their facilities before you are going to join with them.
(4) If you have done some good projects followed by the “what to do” steps, you have more chance to get a job in this field.
(5) If your intention is only for getting a job in this field, then dont look big MNC companies & big salary. You have lots of small embedded companies are there. For entry level, small companies are best to learn a lot in this field rather than the big companes. so your first preference should be small/startup companies.
(6) Suppose you cant get a job in this field after one year, now you can put 1+ yr fake experience with reasonable projects. I did not suggest this idea in previous topic. But here I am suggesting you; Bcoz some time it will work. But its not guarantee and more risky. At the same time, you should have all capability to manage the technical stuffs equivalent to 1+ yr experience person. Interviewer can easily identify you; But he/she may prefer you, due to some reasons. First one is, you have the capability to manage the technical stuff without exp. Second, they are forced to recruit a person for emergency and ready to give an chance for you. Better, go to or; search an embedded systems project which is suitable for you; If possible participate in that project, voluntarily. Or atleast download the source code; learn everything first and then put this project in your CV.
(7) Last but not least, keep on trying ,even you failed in many interviews.

I wish you all the best for your best career in Embedded Systems…. 🙂

Posted in General tagged , , at 9:50 am by asprakash

Recently, we tried to boot our customized Puppy live linux from pen drive in our Intel 201GLY Mini-ITX board. But we gor the error:: /bin/sh: Can’t access tty; job control turned off
For the last one month we cant solved this problem. Now we solved this problem .
The solution is, just boot the kernel with the option, “acpi=off”.
The following steps will provide you more details,

  1. Boot your computer so that GRUB is displayed.
  2. Press the “e” key to go into edit mode.
  3. Presso” to add a new line to the script.
  4. Type the following: acpi=off irqpoll
  5. Press the Escape key.

In the event that acpi=off doesn’t work try replacing the entry above with one of the following:

  • acpi=force irqpoll
  • nacpitimer irqpoll

Hope this info helpful for the people those who are seeking the solution for this problem.

Howto create Bootable USB Pendrive for Puppy Linux

Posted in General tagged , at 9:48 am by asprakash

How to create an bootable Puppy Linux for USB Pen drive:
I tried this step for my IGB Transcend USB pen drive. Hope it will work in other brands also.
Download puppy-3.00-seamonkey.iso from
Here the bolded words are commands.
login as a super user in your host linux
Insert your pendrive.

Mount d pen drive:
#mkdir /mnt/usb
#mount -t vfat /dev/sdb1 /mnt/usb/
If you want any backup of your pendrive, take a copy from it.

# Now type fdisk -l to list available drives/partitions (note which device is your flash drive Example: /dev/sdb). Replace all instances of x with your flash drive letter. For example, if your flash drive is sdb, replace x with b.
# Type umount /dev/sdx1
# Type fdisk /dev/sdx

* type p to show the existing partition and d to delete it
* type p again to show any remaining partitions (if partitions exist, repeat the previous step)
* type n to make a new partition
* type p for primary partition
o type 1 to make this the first partition
o hit enter to use the default 1st cylinder
o type +750M to set the partition size
o type a to make this partition active
o type 1 to select partition 1
o type t to change the partition filesystem
o type 6 to select the fat16 file system
* type n to make another new partition
* type p for primary partition
o type 2 to make this the second partition
o hit enter to use the default cylinder
o hit enter again to use the default last cylinder
o type w to write the new partition table

# Type umount /dev/sdx1 to unmount the partition
# Type mkfs.vfat -F 16 -n usb /dev/sdx1 to format the first partition

“Alternately you can try mkfs.vfat -F 32 -n usb /dev/sdx1 (doesn’t always work)”

# Type umount /dev/sdx2 to ensure the partition is unmounted
# Type mkfs.ext2 -b 4096 -L casper-rw /dev/sdx2 to format the second partition
# Remove and Re-insert your flash drive
# Back at the terminal, type sudo apt-get install syslinux mtools [if you are using debian/ubuntu]
# Or you can install with yum install syslinux mtools [if you are using fedora]
# Type syslinux -sf /dev/sdx1

Copy the iso files in local directory:

#mkdir puppy_temp
#mkdir puppy_usb
#mount -o loop puppy-3.00-seamonkey.iso puppy_temp
#cp -a puppy_temp/* puppy_usb

Note:: From this step, we have copied the content of the iso image into a new you can work on it. If you try to copy this data directly to the USB memory stick, it will not boot because we need to fix the position and the naming of the files. With the consolde opened, enter the following commands.

Boot file modification:

#cd puppy_usb/
#mv isolinux.bin syslinux.bin
#mv isolinux.cfg syslinux.cfg
cd ..

Now mount the pendrive again and copy the puppy_usb directory files to your pen drive.
#mount -t vfat /dev/sdx1 /mnt/usb/
#cp -a puppy_usb/* /mnt/usb/
#umount /dev/sdx1

Make it bootable:

#syslinux /dev/sdx
Note:Ensured that you have installed syslinux. If you will get the error “command not find”. Then you need to instal syslinux
Now reboot your computer, leaving the pen drive inserted; Modify the BIOS boot device and let the system ot to Puppy on the memory stick.

Hints for BIOS setting:

Reboot ur computer and press F2 for enter into BIOS setting. F2 may be varied in your pc. check the pc when it boot.
Once you entered the BIOS setting, come to “Boot sequence” option. Select the USB-HDD or USB-ZIP and move it for boot first. Means, set the highest priority.Now save it and reboot.
Play with Puppy!…

How to configure Your Cell phone in Linux OS for Internet connection

Posted in General tagged , at 9:45 am by asprakash

I tried this steps in Ubuntu OS from My Sony Ericsson K510i. I am using Airtel Subscriber.
Hope it will work in other Linux distros also.

Step 1:
Start your pc and now enter id root and password (you must be knowing that!) Now open terminal and type “dmesg” It will detect all the device connected with your pc including your (usb, serial ) data cable.and it will display log in the same terminal read that log carefully now check which port has been detected by it. It detected ttyUSB1 on my pc.

$wvdialconf /etc/wvdial.conf
it will detect ur mobile and it will write the value on wvdial.conf file in etc directory.


Now open the file /etc/wvdial.conf from your terminal,
$vi /etc/wvdial.conf
In that file, you can show a existing configuration. You just remove all the lines and paste the following code.

#Paste the following lines to your wvdial.conf file
[Dialer Defaults]
Modem = /dev/ttyUSB1 #note1
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
stupid mode = 1
Modem Type = Analog Modem
Phone = *99# #Note2
ISDN = 0
Username = a
Password = b
Baud = 115200

#Note1: May be varied depends upon your hardware config.
#Note2: First check your mobile phone dial No.

Step 3

Open the file, /etc/resolv.conf and enter following lines. Now dont delete the existing lines. You just append.

service named start

Now log out and log in as User and open terminal now type su – and press enter, than type root password for your super user mode.
Then type wvdial R in your terminal
Hope now you are connected to Internet now enjoy surfing . If u want to disconnect than just press CTRL + C or killall pppd
And it will disconnect active connection!.

$sudo nvidia-glx-config enable
Then retsart the Laptop. Now almost the video problem will solved.

* Updated the packages.[kernel also updated]
* Installed build-essential from package manager. It has resolved lot of dep problems.
* Downloaded alsa-driver-1.0.15rc3.tar.bz2
* Untar it
* $./configure
* $make

* $make install

* $./sndevices
* sudo vim /etc/modprobe.d/alsa-base
added this “options snd-hda-intel model=acer” in almost last line. Aft that save it.
* Reboot
* Now my lapy logged in with nice Ubuntu sound. Now the sound card working fine.
Thanks to ALSA and Ubuntu….
This is the common steps for all the distros.
Have Fun..

My short term goal-It should be guide for beginners

Posted in General tagged , , at 8:37 am by asprakash

I was thinking about this short term target in my life since my college days. Early when I entered into my college, I struggled for lot of (Non)technicals issues. Coz I dont have any seniors. In my college we are the first batch students. So I cant get the links and guidance for how to do my ideas like How to study (I was a Tamil medium student), How to learn, How to do a Mini project, Where can I get the resources, How to apply for an symposium, final years projects, job preparation, about companies and of-course How to enjoy my college life.

I faced lot of problems in my job seeking. It was like without any proper preparation, without any guidance and without any motivation. I encouraged myself and finally got a job in my own field of interest.

So on that day itself i planned to launch one site and it should contains technical related stuffs especially for learners, beginners and job seekers. I decided the content and name of the site electronica before 6 years back.
