I didn't say that there was a contradiction. The paper is about QUEL vs. SQL. Given that Postgres/PostgreSQL is introduced, I would think that the initial use of QUEL (PostQUEL), and how and when and why it transitioned to SQL wou

The end of this isn't quite right. The Postgres project started in 1986. I don't recall what language it used, QUEL perhaps, but it wasn't SQL. SQL support was added between 1994 and 1996, and that's when PostgreSQL wa

Your software requirements sound like they dictate the choice. But I don't have those requirements, and my main dev environment is Linux. I ran VM Fusion on a MBP, and I really liked that setup. The Mac was for play, the Linux VM for w

People like and use useful abstractions, and OO offers them: encapsulation, modularity, polymorphism, inheritance. (If you don't like inheritance, don't use it.) People hate bloat, complicated ways of doing simple things, and Abst

In the mid 90s I was at an OO database company, and we were expanding into tools. The decision was made to produce a Smalltalk binding and build tools for that language. That was well underway when Java was released. And you could hear the

This is wrong. A well-known case is the Timsort bug, discovered by a program verification tool. Also well known is the JDK binary search bug that had been present for many years. (This paper discusses the Timsort bug, and references the bin

Thanks, I wasn't aware of that. I believe my comment still applies to nushell and a couple of others. I like bash for simple commands, but hate the requirement to learn so many sublanguages for more sophisticated usage, (as in sed, awk

Marcel is another pipe-objects-instead-of-strings shell. It takes a different approach to shell/language unification, compared to nushell and other modern shells. Marcel exposes Python on the command line, e.g. to find files that chang

Take a look at marcel: https://marceltheshell.org . It is also a shell that pipes objects, and is based on Python, but it sounds like scripting will be more to your taste. There is a marcel.api module that allows you to do shell-
