The fact that many project managers are guided by the cheapest price and requiring «low profile» developers is generating a good percentage of software pieces that can be honoured with the most hilarious posts in The Daily WTF. Also some hiring head hunters which are not able to handle technical resumes because they have no idea about software development, is subject of some gags. No matter how good is a developer, if he does not place numerous times that cool technology which is subject of the job position posted on that prestigious newspaper, he will not be selected and probably that is not a good company where to work.

When to add unit tests?. All depends on how are defined the requirements. If the requirements are well defined, you can add tests on every step in the development, doing evolutionary tests. But if you are working with dynamic methodologies like agile ones, you should add tests only once a requirement is correctly defined, otherwise you will be adding unit tests twice. So, each requirement should have its unit test suite as companion to check that the added feature is working properly.

How did you choose the technology that you are using in your career?. You must carefully choose the technology that you will use. If you know a little about economics, you will be able to understand the fact that if supply increases and demand remains unchanged, then it leads to lower equilibrium price and higher quantity. So, if you use that technology that is sold as the ultimate fast and cheap development tool, you will be underpaid because the price will be lower due to its higher supply than other technologies.

As you know I am learning Haskell and doing small exercises based on the ACM ICPC problem archive. I am using those problem sets as my Haskell practice. The task presented on the problem 1999-c is related to a small DSL which handles concurrency simulations, using two simple instruction called lock and unlock to switch between running and ready states. The DSL defined for this problem seems to be simple. I have used the Parsec Haskell package to build the language parser.

Probably you get delighted by some very nice spots about companies which are hiring new developers, wonderful job posts where you can see that Big Company is hiring new developers or people related to software development. Did you know the type of company where are you applying for a job? Do you know that company enough to ensure that you will be happy?.
