You probably wouldn't know this, but I keep an old computer book on my table.
The title is "Análise e programação de computadores", published in 1970 in Portuguese language by Raúl Verde. Should be noted that the first computer book written in my native language had been published only two years earlier, by the same author.
I keep this book on my table because it teaches the basic principles that an aspiring computer programmer should aim to understand. It focuses on the programming of high-level languages such as Cobol and Fortran. Discusses the tradeoffs between using cards to store data vs paper/magnetic tapes or provide formulas to expose the strong points and make informed decisions.
This book could seem awkward if published today, mostly because it mixes software development with engineering, architecture and business interests that have grown specialized. Yet, these principles remain the same and should row on the same direction. Albeit technology grew and matured, truth is that we keep working to push into new boundaries, squeezing performance out of what is now reachable and to somehow make things work.
In this sense, I find it curious how much of the software I'm developing today is holding a strong resemblance with the old techniques on the book. The usage of flat-files, the console output that helps to monitor results, the considerations about storage and its impact on speed/capacity/costs.
Paraphrasing a blog title, I'm reminded that humans do old new things.
This month I had the task of downloading over a billion files from the Internet on a single run. Compare the writing on this book with the current tasks today, they are not different. Even the term "scale" is no excuse when we place these challenges into context.
And yet, as I look to a thousand lines per minute scrolling through that silent terminal, this gives me a pause of happiness. Data is getting processed, things are working, the system is fast enough.
Each line on this screen represents a repository of code and files for a given person. What kind of work or history was that person developing? Then I think on the millions of other repositories still left to process, this is something pretty to just watch as it scrolls.
In some weird kind of sense for a computer geek, looking at these lines on a terminal feels for me as looking at the stars at night. Imagining how each bright dot is around its own sun, planets and history.
Would these two things be comparable? Perhaps yes, perhaps not.
The old new thing is something to think about.
