These days organization expects their employees to write blogs/publish articles so that the organization gains more visibility. I believe blogs are a very good way by which you can gain more popularity and visibility in the developer’s community. But I see lot of blogs published on company’s official blog as developer’s personal experience or personal learning. These blogs lack the content and value as expected from a company blog. People just write the blog for the heck of writing it.
In my opinion writing such blogs does not increase the organization visibility.There should be a difference between what you should write in your personal blog to what you should write in an organization blog.
The blogs that you should write on a personal blog rather than on company blog are:-
1) Hello World blogs = These type of blogs does not provide any value as you can find such blogs all over the web. They just contain a very basic explanation of the concept or framework with or without a Hello World program. These blogs have one characteristic that the person who wrote this blog will also never read it again.
2) Opinionated blogs = These type of blogs contain your opinion about a topic, concept or an event. Writing opinionated blogs is not bad but
if you are writing your opinion on the company’s blog then it in a way represent your organization opinion also. So, when ever you write an opinionated blog, please match it with your organization values.
3) Blog with links to other blogs/articles= These blogs does not have any content of their own they just point to other links (video or text).
These are some of the types of blogs that should not be written on an official blog. Company’s blog should have good content and quality should matter over number of blogs published. Please post in your comments on what you think.
Reasons for incompetent software developers in India
Most of the times, I have heard that Indian developers don’t have the quality as compared to their counterparts who are working in western countries. Development teams in western countries often blame their offshore counterparts for slowing them down. It has been said that Indians are not technically competent; write poor code, they don’t give any suggestions for the problems, etc.
In my opinion, most of these are true. Yes, we are not at par with developers in western countries and we sometimes really suck. Please note that this is just my personal opinion and not all software developers in India are bad. It’s the problem of quantity versus quality. In this blog, I will be putting up some reasons why I feel Indians developers lag behind developers from other countries.
- Developer by chance not by choice = In India anybody can become a software developer whatever his/her qualification is. I, myself, was a mechanical engineer, but in the college campus was recruited by a Software company so I ended up becoming software developer. Likewise I have so many friends who become software developer by chance. Most of the college students who join any Software company does not know anything about software development or have any knowledge about programming.
- College education does not help = I have graduated from one of the good college in India but I can tell you one thing that the quality of education in India is very poor whichever college you get graduated from. In India, importance is given to marks than to practical learning, students just cram the things and get score but practically they know nothing. I recently interview a guy who had close to 6 years of experience, graduated from a good college in Computer Science with a very high percentage, was not able to write a Fibonacci series program.
- Developers don’t keep themselves updated = If you ask a developer which last technical book you read or how you keep yourself updated, most of the times you will not get any answer. Nobody wants to learn or improve themselves. What more, developers have not even heard about Code Complete.
- Everybody wants to become a manager = In India you can become team leader at 5 years of work experience. Once you become team leader, your next goal is to become manager and for becoming manager you need to be good at giving your work to others, doing dirty politics, and most important doing nothing. So, you can see, we do not know anything about programming when we enter the software development world and at an experience of 5 years most of the developers start thinking about becoming manager.
- No contribution to opensource community = I don’t know any of my friends or friends of friends including me who has contributed to opensource community. We can only use the opensource project and if we find any bug in the project we will never fix it but blame the developers who wrote the code.
There can be more reasons but at this point of time I can think of these 5 only. I am trying to make myself a better developer by reading, writing, listening. Tell me what you guys think?
Today, I was thinking why I and many other bloggers write as anonymous blogger without disclosing their correct identity. I am writing down some reasons which lead me to write in an anonymous manner:-
- Fear of not looking stupid: – I feel this is the number one reason why people hide their identity. This can be related to a blog which does not make sense or poor code examples.
- Writing on the topics which you can’t write otherwise: – There are topics on which you don’t want to write with your correct identity like your workplace environment, your manager J , interview questions and many others. By hiding your identity, you can very easily do this.

Recently i wrote an blog entry on one of the java puzzlers that was asked to me in an interview.I received some of the comments which said this is unfair to ask java puzzlers in an interview.So i thought of writing an blog which discusses whether java puzzlers make good interview questions or not.
Does Java Puzzlers make Good Interview Questions?
I think before answering this question that should we ask java puzzlers in an interview or not we need to define some guidelines about what makes a good interview question. And if java puzzlers fit within those guidelines then we can ask the them in an interview.I am giving my personal point of view please add in your comments if you think something different.
Guideline for a Good Technical Interview Question
- Question should be How not what = Should be Practical which means that Interviewer should not ask the definition of some term or concept the interview question should be such that it discusses practical application of concept.Asking how has the advantage that interviewer gets the correct feedback about interviewee that interviewee actually understand the concept.
- Question should be on simpler concepts = Asking a difficult question doesn’t make an interview question good.In my personal opinion interview question should be about the concepts which a developer normally use. You can vary the difficulty level of question depending upon position you are hiring but the concept should be simple.For example you can ask questions on overriding which can be simple or difficult but the concept of overriding is such that every java developer should know.
- Question can be Extended = A good interview question should be such that you can build your interview on that question which means that if you ask a question on overriding you can start with the easier question and then build your interview by asking questions that increases in difficulty.
- Question should not be specific to API = The question that i mentioned in my post was good but it was specific to the HashSet remove method arguments. Let me explain, when you create an hashset like HashSet<Short> s = new HashSet<Short>() you might expect that when you are doing s.remove(i-1) should remove only short objects but when you take a look at the remove method it takes Object .This is something specific to api which most of the developers might not know. So asking such a question becomes useless.
- Question should provide a learning point = A good interview question should provide a value add to the interviewee. It might be possible that interviewee knows everything which is great and you can hire him/her. But even if he/she doesn’t know the answer they can at least learn a good technical point.
Does java puzzlers fit these guidelines?
In my view java puzzler fit some of the guidelines:-
- All Java Puzzler are about How not What so java puzzlers can provide interviewer the practical understanding of the interviewee.
- Java Puzzlers are about simpler concepts but the Puzzlers are not simple because they discuss the trap or corner cases of the API. You can use these concepts for interviews but the questions are very specific to api and most of the times should not be asked in interview.
- Java Puzzlers can be extended but again because they are not easy most of the times you will not get the correct answer.
- Java Puzzlers are specific to API and they require very good understanding of java api.
- Java Puzzlers definitely provide a learning value to interviewee because these questions touches the corner cases of the api which normally developers doesn’t know.
In my view you can ask some of the java puzzlers in an interview as java puzzlers definetly provide a value. Sometimes you should only take a concept and build you question on that and sometime take the whole question. If you think the java puzzler you are asking is difficult and a normal developer who hasn’t read java puzzlers book can’t answer please dont make that question a decider question means your decision to hire a person should not be based only on java puzzler. Java Puzzlers are definetly very good questions and you should use them wisely in interview.
These are some of my view points. Please share your also.

I am trying to express my views on the problem which i think google search pose to developers in terms of limiting the ability of software developer to solve problems.May be my point of view is totally irrelevant to many of you but i think getting every answer at the click of just one google search button leads to under-utilized brain.
In my personal day to day work whenever i am struck with some problem and i think i just can’t think more i just do a google search and try to find the solution to my problem. If the solution which i get by viewing the first few links(which we all normally do ) on google search page are relevant to my problem i will integrate(after understanding the solution) that piece of solution in my code and move to the next step/task.
Problem with this Approach
- Easy way to get solution :- Once you know that you can find every solution to your problem by googling it becomes a habit and most of the time without giving proper thought or applying your mind you just do google search.
- Brain not optimally used:- Because more than often we are relying on search results to give us the solution to our problems we tend to let search engine become our brain and leaving the brain we have do nothing.
- Lazy Developers :- This also leads to developers becoming lazy in solving there problems themselves.
- Solution doesn’t work as expected:- Because you are not giving your 100% in finding the solution to your problem leads to the another problem that you have not fully understood your problem and the solution you found by googling was just a partial or incomplete or even wrong solution.
- Time Waste :- It happens that you try to put time on solution which are not the actual solution to the problem leading you to tweaking the piece of code to work the way you want and finally if it doesn’t work you just delete the whole piece of code and start thinking in a better way.
Above mentioned are few of my concerns that i can think right now but i think there will be many.
Please share your thoughts also even if you think what i am saying is totally rubbish
