Find 2 or more solutions for each problem you meet

Improves problem-solving & creativity

Whether your current task is debugging, writing new code, or refactoring, dev missions are all about problems and solutions. The problem scope can vary, from reusing existing code to choosing a database.

Even if you already choose the solution, take the time…

I'm writing the story of a big refactor task; what were the main decisions along the way.
I list the trade-offs and how I managed to make big progress in a short time.

What was the Problem?

Our business logic layer holds ‘Applications’, classes that represent features. It was not written to scale, and we had many apps each in its own thread with callback and dependencies between them.

The problem was that we didn’t know when we will hit a race condition or deadlock. To fix such a bug, we would…

Making Mistakes is like Diamonds — they are forever

When I was a junior developer I was terrified of Git- I feared a wrong action would break the main branch for all the developers and QA, with all the public shame that comes with it.

Background about the hackathon

For the next product my company wants to develop, the R&D decided on 2 mini-hackathons. In the first one, we researched technologies and came up with a nice list of options. In the second one, that was today, each of the 4 teams got a product and was asked to create a working Proof of Concept.

What the hackathon was like

Ports are communication endpoints, thus they are the main suspects when we have communication problems.

Recently I was dealing with a bug where client-side failed to reach the server in an application I was running. Since both server and client were third party, I couldn’t change the code directly. I summed up my debug steps and how to troubleshoot such cases, along with examples of my go-to commands.

None of us choose debug-science as a career. We want to imagine and create, not dwell on the bad and the broken. But in our world, bugs do happen and we do spend time solving them. How much time? Quite a lot actually, up to 75% of our time (according to Coralogix).

Do you have time for time // Problem introduction

Time is an abstract concept, an idea that should not be tamed. However, we humans try to force our laws on it, breaking time’s spirit into days and hours and then confusing it even further by stating that the time now in Arizona is different than the time In Belgium! …
