  Accessing Reddit top posts using OAuth

Previously one can use the https://www.reddit.com/r/rprogramming/top.json API to access one subreddit's top posts. This API doesn't require any access token to fetch the data. However, this API may not work all the time. Reddit may block the API's request if it finds that you are using a script or some app which accesses the API now and then. For an app or script which needs to fetch the data routinely, what should we do? Reddit provides one method which can be used to fetch this kind of to...

  Benefits and Drawback of a Layered Architecture

Most enterprises today are application centric. But the problem with the application is that their database schemas, user interfaces, programming interfaces and object models are tightly coupled and difficult to change. If you want to add a new field to a database table and you’re lucky, the change will reflect through the entire system. But often the change needs to be replicated manually across the entire system. And as applications are difficult to change, adding business rules or proce...

  Automate Everything

Performing manual, repetitive tasks enrages me. I used to think this was a corollary of being a programmer, but I’ve come to suspect (or hope) that this behaviour is inherent in being human. But being able to hack together scripts simply makes it much easier to go from a state of rage to a basic solution in a very small amount of time. As a side point, this is one of the reasons that teaching the basics of programming in schools is so important. It’s hard to think of any j...

  HeartBleed: Inside the heart, what happens to a normal WEB user?

To be brief, our email, IM, facebook etc. are at the risk, so try to minimize the access in these few days. Especially we should try to avoid log into our internet-banking, because we may expose our user id and password. Also later when the service providers fix the bug, we would better to change a new password for all the web accounts that are important to us. Here comes the technical explanation. You might notice before that a lot of websites use URL starting with "https". For example, https:/...
