Doing software development from bottom up when you need to or is this a norm?

Doing software development from bottom up when you need to or is this a norm? If somebody asked you to first build the wheels for the car before having the car at all, what would you do? First, I would question if I need to design/build 4 lug or 5 lug wheels. Then I would need to predict or ask about some details to figure out the proper offset and width for the wheels so they don’t stick outside the fenders. Now how does this car analogy apply to software engineering? First, you need to know and define the API contract. Then you would probably build a stub or mocked version of your API and you would put yourself in the shoes of the client trying to use it in cases that you can predict. Depending on the performance requirements, you may end up adding caching and other improvements. This approach is actually not that uncommon. This is actually how you would approach your team to team and microservice to microservice dependencies regardless of how well you know your consumer; it is important to maintain that discipline at the technical level but as for human communication leverage the closeness you have with other teams.

Brand New programming language and one solution OR …

Brand New programming language and one solution OR Two existing programming languages, one solution for EACH? I understand that there is no right or wrong. It all depends on your software architecture, team structure, team skills and other factors, but I still want to explain the scenario as it may look familiar to some. Let me explain. Let’s assume that you have microservices and common libraries in two major programming languages. You have some teams who are experts in one and some teams experts in the other programming language. Now you need to come up with a solution for a scenario that all teams will need to leverage. Let’s assume that your cloud platform has an off-the-shelf approach for this but it is supported by a 3rd programming language that your teams do not have much experience in. What is the right thing for your organization and not just from the technical point of view? A) Do you embrace what your cloud platform gives you off the shelf and implement thi...

10,000 foot level view in technology

10,000 foot level view in technology: How useful is it? What can be done at this level? If the 30,000 foot level is the CTO level, then consider the 10,000 foot level as the level that software engineering managers and directors operate at. To achieve the success at 10,000 foot level, you as a software engineering manager need to dive deep into technical details, help the team lay the foundation from BOTH organizational and technical side. It is the little moves that get the team to this level. Once the team’s applications and results at that level, then you as a manager have ability to perform the high level analysis and troubleshooting without necessarily being in code on daily or weekly basis. Therefore, your ability to troubleshoot technical issues at the 10,000 foot level is a testament to the great work of your team. Go TEAM !! Almir Mustafic

AMAZON WORKSPACES

AMAZON WORKSPACES. I am not sure how many of you have heard of Amazon WorkSpaces. Let me give you some information and my analysis after using it for some time. What is it? It is the Amazon’s solution to desktops in the cloud. What’s the point? Well, if you want to use a basic less powerful laptop or even use a Chromebook as your daily computer, then you will not be missing the full functionality of a powerful Windows 10 machine. For example, you can use your Chromebook to connect to your Amazon WorkSpace machine and then you get the full Windows 10 experience. The point is that it gives you the experience as if your remote/workspace Windows 10 machine is really part of your Chromebook. Where it makes the most sense is using Chromebooks to connect to your Amazon WorkSpace machine as Chromebooks with Chrome OS are fast for anything you do in the browser and they are very secure; Chromebooks are also generally cheaper than other laptops. Just a thought as an alternative to buying ful...
