As a database designer, when you are tasked with a database project, you can expect to run into a couple of challenges during the design process and after the database is deployed to production. Some of these problems are unavoidable and outside your control. However, a number of them can be traced back to the quality of the database design ...

Introduction In Java, threads can have States. The Thread.State enum defines the different states that a Java thread can have.

Besides developing their business propositions, companies had to develop, maintain and operate the platform on top of which their businesses (i.e. applications) run. Until Cloud options and “X ...

Previously we used the state in order to add some functionality to an application based on the user state. Our next behavioural design pattern is Strategy. The strategy pattern enables us to select an algorithm at runtime. Based on the instructions our program will pick the most suitable algorithm instead of implementing an algorithm directly. This makes our codebase more ...

Last week I was pointed by someone to Active Patterns in F#. And it has been quite an interesting discovery. Active Patterns are used on F# to partition data. Those partitions then can be used with pattern matching. Microsoft’s webpage compares them to discriminated unions. How they can be used? Well, you could look at the above link, or just ...

So I had this naive idea that it would be easy to do certificate transparency verification as part of each request in addition to certificate validity checks (in Java). With half of the weekend sacrificed, I can attest it’s not that trivial. But what is certificate transparency? In short – it’s a publicly available log of all TLS certificates in ...
