When there are multiple options for a decision, each decision outcome should be exercised before moving on to the next decision. Finally, once all the decision outcomes on the baseline path have been covered, apply the same approach to all subsequent paths until all the decision outcomes in the specified code have been exercised.

Google has announced plans for a new badging system that would let users know whether a website typically loads slowly. While it is seen as a positive for users to be able to quickly see if the site they’re loading is slow, the ethics of such a program become a little murkier. Wrapping up and looking forward.

This ruling in itself raises many questions: how much creativity is needed, and is that the same kind of creativity that an artist exercises with a paintbrush? However, that design issue isn’t germane to this discussion. Tracing provenance with these more complex systems will be difficult—but with RAG, we now have the tools to do it.

I've worked with quite a few companies for which long-lived software assets remain critical to day-to-day operations, ranging from 20-year-old ERP systems to custom software products that first processed a transaction way back in the 1960s. The first and most obvious is that they are long on how to start, but short on how to finish.

Build a more scalable, composable, and functional architecture for interconnecting systems and applications. Software today is not typically a single program—something that is executed by an operator or user, producing a result to that person—but rather a service : something that runs for the benefit of its consumers, a provider of value.

It’s also awkward, an exercise of the blindfolded people describing the pachyderm. Some of this is likely a function of professional programming: if, for the totality of your career, the boss has supplied you with the reason why you do the things that you do, it isn’t natural to start a new initiative by asking “why”. And that’s ok.

After this, the micro-ops will wait in the Reorder Buffer until they can be retired in program order. Instead, we found puzzle after puzzle.
