How debuggers work in Lispy languages

schedule Nov 16th 12:00 - 12:45 PM place Meeting Room 1 people 18 Interested

Debuggers are one of the most essential tools for any kind of development.

Debuggers in Lispy languages make use of Lisp's homoiconicity. They are a bit different from debuggers for languages like C or Java.

This kind of information is usually not needed in day to day development and hence it remains hidden.

In this talk, I will take Clojure's cider-debug as an example and explain how it uses homoiconicity. Along with cider-debug, I will also talk about REPLs and how REPL client-server communication happens (with nREPL as an example).

 
 

Outline/Structure of the Talk

1. What is Homoiconicity.
2. REPLs.
3. REPL client-server communication.
4. Lispy debuggers with cider-debug as an example.
5. How debuggers for lispy languages are different.
6. Internals of lispy debuggers.

Learning Outcome

Good understanding of:
1. Debuggers for Lispy languages.
2. REPL client-server communication.
3. Overview of cider-debug features.
4. Internal details of cider-debug.

Target Audience

1. Developers who work with Lispy languages. 2. Developers interested in knowing how debuggers work. 3. Clojure developers.

Prerequisites for Attendees

Begginer level knowledge of any Lisp like language. Even better if it is Clojure as I will be using Clojure in this talk.

    Hello Suvrat,

    Thanks for your proposal! This is an interesting topic.

    In order to help the program committee to understand your presentation style, can you please upload a video of your past presentations? If you don't have one, can you record a small 1 mins trailer of your talk and share the link to the same? 

    Thanks,

    Deepti

      Hi Deepti,

       

      I don't have a video of a previous talk. But I do have slides of a talk I had given on "Objective-C Internals". It was about how Objevtice-C implements object orientation using plain C.

       

      About the debuggers talk, I can make some slides and send them over.

       

      Another thing I was thinking about was - Instead of a Lisp debuggers talk, should I give a Clojure specific debuggers talk? That could be a 20 mins talk.

        Hi Suvrat.

        It's okay about not having a previous video. We think the topic is definitely interesting, but are keen to also have a glimpse of your presentation style to help us decide. For that, a one-minute video+audio talking about some portion of your topic will be a good idea. You need not worry about how the entire thing is coming together right away. Maybe, just show how you'd introduce homoiconicity to audience (to give an example).

          Do you want a video of me? Or will a screencast of my content + my voice be okay?

      Programs are getting fat. They're becoming slow. They're taking up more computing resources. They're getting harder to maintain and more complex from the ground up. Layer upon layer of sophistication is causing us to lose our ability to predict what software will do. Where's that bug? Why is everything going so slowly? Am I even using the right data structures? Where's that important point in the documentation again?

      What's happened to us? In this meta-dive into the nature of our approach to programming, we will explore some of the dangers of our current approaches to programming and the how/why of our current programming obesity problem. We will look at real case studies and see just how bad the situation can be.

      But we will also explore how we can battle these sources of obesity. In this passionate plea for code that we can gain control over again, we will look at examples of how we can return to a state of high-performance on all levels, from code size to code scalability. We will look at the principles that can help us to reach leaner, more efficient, more usable, less buggy code. We will hopefully find some light at the end of the tunnel, and how we can change our outlook on programming to push ourselves towards code that benefits not only ourselves, but also those that will come after us.

      If you are writing a stateless web application backed up by a database, there is a good chance Elixir is a great fit. However, this is not where it shines. In this talk, we will discuss how to architect Elixir applications in order to leverage the features of the language and of its runtime.

      We will look at this both from a lower level, talking about the architecture of processes inside an Elixir application, as well as from a higher perspective of writing Elixir services and architecting systems to play to Elixir's strengths. We will see practical use cases and discuss design patterns.

      Sylvester is an F# DSL for scientific computing which implements an advanced type system where vector, matrix, tensor, neural-network and other types have numeric properties like dimension sizes, rank, layer node size, etc., encoded as part of the type. Type-level constraints for operations like matrix multiplication or network layer construction utilize the F# type checker as a type-checker for linear algebra and other mathematical domains which allows for type-level verification of mathematical operations and for Intellisense-enabled IDEs to provide immediate feedback that helps the user avoid errors in mathematical expressions..

      One of the strategies being adopted by RoR or Java software developers in adopting Elixir is they have not yet adapted themselves to unlearn the OOP in developing the web systems. This has caused OOP concepts to creep into full fledged Elixir systems. This presentation seeks to highlight these subtle points that need to be avoided to make the code more FP and less OOP.

      Functional Programming is going through the same process of rethinking as Object Oriented Programming has passed already. FP today is not only something mystical, something barely applicable for day-to-day tasks, but rather a whole philosophy of building big, complex applications, with own tools, approaches and methodologies. We can see a lot of ideas about software design and architecture emerging from the FP community: talks, books, articles. We’re actively discussing Final Tagless, Free Monads, effect systems and other approaches, but it seems the theme not yet covered and we don’t know about possibilities we have.

      In this talk, I’ll tell you about the power of Free Monads in building complex applications in Haskell and PureScript. These applications will be satisfying the requirements like maintainability, testability, simplicity. You’ll know how to create a safe concurrent application state, how to divide the application into layers and how to keep the code sane. In fact, you can do the same with Final Tagless or extensible effects, but the approach with hierarchical Free Monads has some specific properties making it the best tool to separate concerns and create a very interesting eDSLs with different semantics.

      The talk is based on the ideas I’m describing in my book “Functional Design and Architecture”. I also gave several talks about this theme earlier (you can find all my talks here).

      I’ve used these ideas to build software for different companies, including Juspay (Bengaluru), Restaumatic (Poland), Enecuum (Hong Kong). We’ve created several interesting technologies that were not possible to make without Free Monads. Some of them are open sourced.

      At Helpshift, we face managing complexity of these side effects which touch 10s of different systems. Each side effect poses a failure scenario which can lead to it's own business decision. Compounded failures pose even more complexity. To add to the problems we extending the codebase to add new business logic regularly.

      I will present a solution which is a combination of Clojure and FP following techniques. We will also discuss how ideas when combined together can create an elegant solution,

      1. Data - Side effects definition as data

      2. Almost no syntax - Minimal definition

      3. Many functions for one DS - Multiple execution and failure recovery modes for side effects

      APL is getting a lot of attention lately due to its potential for very high performance portability and suitability for both rapid prototyping of complex solutions as well as deployment of complex algorithms to high-speed, modern parallel hardware. It has the potential to vastly improve the speed, scalability, and size of your code bases. But APL has a reputation as an intimidating language to learn.

      In this back to the basics tutorial, we will explore the core of APL, and focus on those areas that usually trip up the beginner in learning APL. We will also walk you through how to approach an APL expression, how to reason about them, and how to read them efficiently. We will teach you the skills that the expert APLer has internalized, and how you can work through these skills externally and explicitly in a way that will help you to eventually internalize these critical skills in a way that makes you efficient at using APL on real world problems.

      'Let it crash' gets thrown around a lot in the Erlang community. An experienced
      programmer (with understandably different experiences) on first encountering
      this idea in Erlang is often found asking what we let crash? And what happens
      after?

      I will attempt to answer this question.

      Erlang puts distributed systems programming ideas front and center. We'll also
      talk about this in the context of letting processes crash and how that affects the
      design of our software.

On the other hand, there is a high cost of on-boarding new developers and few other pain points. So, is Haskell worth the investment?

      As machine learning matures, it is becoming obvious that we need explainable solutions. As functional programming matures it becomes obvious that we need inference and nondeterminism. And linked open data demands reasoning. This all day workshop will introduce the logic programming paradigm, in which programs are expressed as a set of logical rules and executed by finding proofs of queries.

      SWI-Prolog is the most highly developed and widely used language for logic programming.

      The language, which has been in continuous use in academic research settings since it's invention in 1972, provides unparalleled power. Many problems which would be difficult to express in other languages are simple in SWI-Prolog. SWI-Prolog is a 'batteries included' modern language, ready for real world tasks like web development and process control.

      In this dynamic hands on workshop we'll learn the basics of SWI-Prolog, and look at some of the amazing things it can do.

      Erlang has been in production for more than 30 years and a highly battle-tested robust system, which is being used by everybody including Telecom systems that provides 99.99% uptime. Elixir has been built on top of Erlang overcoming the shortcomings of the language and also using meta-programming, it has opened a new paradigm of looking at the language itself. I want to show what Elixir is to the audience and minute nuances that every experienced or inexperienced developer should be aware of before jumping into the magical erlang and elixir world.

      Having spent more than 10 years 'learning haskell', on and off, 4 days a month,
      4 months a year (in a good year), you know you're better off writing enterprise
      Lisp for the rest of your career.

      But suddenly out of nowhere you find purpose, and now you need to build a game.

      This is that game.
