Engineering requires more Science

Peter Drucker once said, "Culture eats strategy for breackfast". Technology is a very awkward field. In theory, we came from Math, science thinking should be our default mindset but we are far from it. We need science more than ever, as a society we are living a pandemic crisis, for sure will lead to some sorta ice age economical period who not only is never saw at this scale but also nobody can tell for sure what will happen. So yes, we need science because of the need for a COVID-19 vaccine and cure but we also need that in Software Engineering and Digital products. For some reason we are losing the basics, we are losing how to build software properly. Mostly because people don't understand how technology should work. Deming, one of the founding fathers of Lean once said Second-grade teacher creates second-grade students.  Crises times are often tough and difficult but for sure there are opportunities not only to improve things but also to re-think what we are doing.

Technology Flat Earthers

Flat Earth arrived in technology a long time ago with TDD and Clean Code. There is no scientific evidence proofing that 10-15 lines code means that the code is bad. TDDs claims to improve design but making features with tests. This is like losing weight by eating. What is funny is that in Flat Earthers there is no scientific proof and they believe just because they believe. TDDs/CleanCoders often fight like there is no tomorrow, and most of them never ever read the clean codebook. For sure we need a Detox.

I was thinking and actually is much worst them TDD / Clean code, our entire field losing senses. It's funny because we are leaving a technology moment where Data Science and Machine Learning are growing like crazy and are realities. So the question is why are we not applying Science to Engineering like we are going in Data Science?

We live in a are where everybody has an opinion and you need to hear people's opinions no matter is they are completely based on bullshit and people don't bother to even read 1 book or do any basic research. So I believe we are living a kind of middle age are of technology where there are lots of things we dont understand and we do not want to understand because we just choose to have feeling over-engineering, feelings over science, feelings over reality, feelings over sense.

Wrong values

Do not get me wrong. Collaboration matters, listen do your work-maters matter, however we need to be able to apply the right values. Otherwise, we will have very poor and mediocre results. For instance, it's important to everyone has a voice, for sure. But if you are saying 1 + 1 = 42. There is nothing to argue, there is no reason to listen and fulfill bullshit and fantasy. That's the big issue I see going one now, everybody wants to add value to the table, which is great but very feel and studying and doing the homework properly to do it so in the way that makes sense.

So going back to the values, what really matters? Have the FAKE sense of Adding value and being right and have an opinion or LEARN and do the right thing? Agile and Lean are about Effective Learning. In order to learn we need to be humble and say "I don't know".

Science-based movements

Deming was a statistician and Lean end up rasing from the manufacturing floor. Lean was always in favor of Data. Data Science is. In Data We Trust! Amazon, Google, and several SV companies are Data-Driven. DevOps is about data and is about proper learning.

Lean Startup is about experiments and assuming you dont know and you need to validate your assumptions with experiments. Product discovery goes on the same track, we need to validate our ideas with several experiments like User Surveys, Landing Pages, A/B/N Testing, Wizard of OZ and so on and on.  Functional Programing is based on Math. All new languages have functional programming concepts that are going more and more into the rabbit hole.

How to Improve? 

If you are an engineer get back to the basics: Algorithms and Data Structures, they matter, stop trying to fix everything with a relational Database and some old OOP language. Software Design matters and if you did not read it yet I recommend read the Philosophy of Software Design. If you are a Software Architecture you need to make sure you have clear and real use cases and do proper Trade-Offcs, Pocs and benchmarks to make sure you are on the right track. 

If you are a discovery professional like Ux or Lean BA you need to make sure you apply science in your experiments and follow the scientific method. If you are a manager do not manage by common sense in numbers, understand why something happens, work with RCAs, 5 whys and system thinking tools. Increase your talent density and hire engineers with a science mindset.  More process and control you have, more slow your system will be and worst results you gonna get. Sharing is caring, make sure information flows and there are regular training, Lighnigh talks, Dojos, Hackathons, Code Rethreads, Host meetups, and incentive open source commitment.

Cheers,

C Unit Testing with Check

Image
When I start on IT, several years ago(+15), C was the first language that I learned. But was not the first language I mastered and deployed in production which was...surprisingly Visual Basic 6.0. However, when I learned C or any language back on that old and arcane time noddy was into testing. However now is impossible to work professionally in any language without tests. C is a low-level language but still kicks ass and has several interesting libs/frameworks. People use to fear C a lot because of lack of syntactical sugar but once you get used to it is not that hard at all. Today I want to show how you can do Unit Testing with C. I will not show how to do Unit Testing with C++ but with C ANSI actually. We will be using Check a unit test lib for C ANSI.

Having fun with Zig Language

Image
Zig is a general-purpose language created in 2016 by Andrew Kelly .  Zig aims to fix the issues C language has while being pragmatic and simple at the same time. Zig really shines as being simple by not having any hidden control flows, not having hidden memory allocations, no pre-processors, and no macros. Basically, it's one language and one language only. Since pre-processors and macros can get really complex and become their own universe. Sure it's not the Zig Philosophy.  Zig Compiler(Zig cc) also is a C compiler, and the interoperability from C to Zig is very good. Clearly, we can see influence from other languages like Go and Rust; however, Zig is pretty unique and different from Go and Rust.  Zig is fast. Zig is perfect for system programming. I bet we will see a lot of solutions being built in Zig. As a languages aficionado, I like to learn at least one language per year and sometimes more; Zig was my 2021 pick, did not regret it. Even if you dont use all language...

HMAC in Java

Image
In 2018 AWS CTO(Vogels) said : "Security is everyone's job". For the last 2 years, there was so many famous and big data leaks and breaks that made that statement be very true more than ever. Security often could mean worst performance and worst user experience so in order to get it right you really need to think about the designs before jumping into to code and consider performance and user experience has main requirements.  I was thinking about writing about how to do HMAC in Java for a while and recently Redis 6.0.0 come out and to my surprise, there was a refactoring on the password part in order to use HMAC.  Security easily could scare engineers often because it is not something well spread yet but I believe this will change soon. It does not matter if you have to deal with PII Data or not, security is super relevant because everybody is running their workloads at the cloud or with IoT and Edge devices which means more distribution, more code, more points of fail...
