My opinions for Computer programmer

Programmers who don’t code in their spare time for fun will never become as good as those that do.

  I think even the smartest and most talented people will never become truly good programmers unless they treat it as more than a job. Meaning that they do little projects on the side, or just mess with lots of different languages and ideas in their spare time.

Not all programmers are created equal.

  Quite often managers think that DeveloperA == DeveloperB simply because they have same level of experience and so on. In actual fact, the performance of one developer can be 10x or even 100x that of another. It’s politically risky to talk about it, but sometimes I feel like pointing out that, even though several team members may appear to be of equal skill, it’s not always the case. I have even seen cases where lead developers were ‘beyond hope’ and junior devs did all the actual work – I made sure they got the credit, though.

The only “best practice” you should be using all the time is “Use Your Brain”.

  Too many people jumping on too many bandwagons and trying to force methods, patterns, frameworks, etc. onto things that don’t warrant them. Just because something is new, or because someone respected has an opinion, doesn’t mean it fits all.

Add .json file in asp.net web.config file

 How can I enable the download of *.json files from an old ASP.NET site (IIS6 I am led to believe)?

 I am getting a 404 page instead of the JSON file.

 Do I need to create a web.config file? What goes in it?

you can just add the following to your web.config in the system.webServer section:

<staticContent>
    <mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
