Programmers and software engineers seldom do. I think learning the concepts should come before learning the alternate UIs, but, of course, other people may have a different preference.I think that PlusCal is nice when specifying sequential and concurrent algorithms, while specifications of complex distributed systems may well do without it.Folks interested in modeling systems this way, but with, I think, an easier-to-use tool than TLA+, may be interested in Folks interested in the relationships among mathematical proof, types, and software may be interested in type-theory-based proof assistants, such as Folks interested in programming, where you can, in the same context, provide proofs of properties of your program, may be interested in Folks interested in languages with slightly more commercial uptake than the previous three, but that still allow you to use types to express significant correctness constraints, albeit with quite a bit more effort, may be interested in Disclosure: I'm a professional Scala developer doing pure functional programming in Scala, have dabbled with Coq pretty extensively (although it's been a while), and have dipped my toe into Idris.I'm also not quite sure what you mean by "modeling systems The main differences between Coq and TLA+ are about scope and pragmatism.

I have immense respect for Lamport and think TLA+ is an incredible tool, but I don't think this talk is the best introduction to it. Lamport’s algorithm for determining a timestamp. According to Leslie Lamport, winner of the 2013 Turing Award, thinking mathematically can be a useful step to specifying the algorithm for computer programmes, as it can help programmers clarify their thinking and make programs more efficient. Leslie Lamport is an author on WIRED. Isabelle and Coq also have declarative proof languages but I don't know how much they're used in comparison to the virtually unreadable imperative proofs.New comments cannot be posted and votes cannot be castPress J to jump to the feed. Currently, the machine-oriented approach is more fashionable, but I shall argue that to get beyond the impasse it will be essential to return to the human-oriented approach. Lamport wrote PlusCal in 2009 specifically to make it easier for people to learn TLA+ and it would have been a better choice for the example code in the slides.A couple of intros to PlusCal (and then TLA+) I like are I think that learning basic TLA+ should come before learning PlusCal (which could be done in no more than a couple of hours once you know basic TLA+), as TLA+ is simple enough (it took me two weeks to learn it well enough to be very productive), you need to know it anyway even if you prefer using PlusCal syntax, and it makes you understand the concepts, whereas PlusCal is a rather opaque front end. This is …
Architects draw detailed blueprints before a brick is laid or a nail is hammered.
Leslie Lamport: Thinking Above the Code. A blueprint for software is called a specification. Leslie Lamport invented TLA + circa 1994, as a culmination of about two decades of work on formal methods — techniques that employ formal reasoning, reasoning based on the precise properties of formal systems, to analyze systems. Programmers and software engineers seldom do. Lamport wrote PlusCal in 2009 specifically to make it easier for people to learn TLA+ and it would have been a better choice for the example code in the slides.
If you're a logician exploring new foundations for mathematics, rethinking calculus in constructive math, coming up with new kinds of logic or whatever -- Coq was invented for you, and there would be little (or nothing) for you to do in TLA+. Incidentally, it was designed by Coq veterans. Thinking Above the Code. Architects draw detailed blueprints before a brick is laid or a nail is hammered. Thinking Above the Code.
Programmers and software engineers seldom do. A blueprint for software is called a specification. an hour. This talk explains why some sort of specification should be written for any software. Huffduffed by horatioalderaan on March 31st, 2020. A blueprint for software is called a specification. Leslie Lamport. Leslie Lamport Last modified 20 July 2020.
an hour. I have immense respect for Lamport and think TLA+ is an incredible tool, but I don't think this talk is the best introduction to it. The need for extremely rigorous specifications before coding complex or critical systems should be obvious—especially for concurrent and distributed systems. Read Leslie Lamport's bio and get latest news stories and articles. Leslie Lamport. Architects draw detailed blueprints before a brick is laid or a nail is hammered. If you're a developer who wants to affordably reason about large and complex Another great thing about TLA+ is its declarative proof language, which is probably the best designed proof language out there. Leslie Lamport is the author of some of the most cited computer science papers and won a Turing Award in 2013 for his seminal work in distributed and concurrent systems. “Most programmers just start writing code; they don’t even know what the algorithm is. Have you seen an awesome talk which is currently missing on this website?
Programmers and software engineers seldom do. It not only lists the papers I have written, but also describes them and explains how I came to write some of them. I have included almost all my technical papers and electronic versions of many of them for downloading.
