I often think about that at work, but in a modified way.If I have something useful, constructive, cautionary, clarifying, or propelling to provide to a discussion, then I should say something or take action. But I've caught myself many times writing up a response to a message in Slack or a story/issue with my opinion on a subject, positive or not, and before hitting "send" thinking about whether I'm actually providing value, whether not speaking would have roughly the same impact on the outcome.Wed, 17 Apr 2024 00:00:00 +0000https://danielgregoire.dev/posts/2024-02-23-signal-to-noise-programming-languages/https://danielgregoire.dev/posts/2024-02-23-signal-to-noise-programming-languages/Fri, 23 Feb 2024 00:00:00 +0000https://danielgregoire.dev/posts/2024-02-08-k-language-upper-case/https://danielgregoire.dev/posts/2024-02-08-k-language-upper-case/K REPL session to define an upper case function.Thu, 08 Feb 2024 00:00:00 +0000https://danielgregoire.dev/posts/2024-01-27-exploring-j-language-array-programming/https://danielgregoire.dev/posts/2024-01-27-exploring-j-language-array-programming/Leveraging these mathematical patterns with arrays as the central data structure leads to largely loopless and branchless programs, in which algorithms are distilled to a series of progressive array transformations.Sat, 27 Jan 2024 00:00:00 +0000https://danielgregoire.dev/posts/2024-01-25-julia-error-message-string-concatenation/https://danielgregoire.dev/posts/2024-01-25-julia-error-message-string-concatenation/The Julia programming language recently delighted me with its error message when I tried to concatenate strings.Thu, 25 Jan 2024 00:00:00 +0000https://danielgregoire.dev/posts/2023-11-11-learning-moldable-development/https://danielgregoire.dev/posts/2023-11-11-learning-moldable-development/Sat, 11 Nov 2023 00:00:00 +0000https://danielgregoire.dev/posts/2023-11-07-functions-messages-words/https://danielgregoire.dev/posts/2023-11-07-functions-messages-words/Tue, 07 Nov 2023 00:00:00 +0000https://danielgregoire.dev/posts/2023-05-26-pilisp-pl-macro/https://danielgregoire.dev/posts/2023-05-26-pilisp-pl-macro/PiLisp's pl> macro for threading expressions.Fri, 26 May 2023 00:00:00 +0000https://danielgregoire.dev/posts/2023-02-23-pilisp/https://danielgregoire.dev/posts/2023-02-23-pilisp/PiLisp—An interpreted Lisp inspired by ClojureThu, 23 Feb 2023 00:00:00 +0000https://danielgregoire.dev/posts/2023-02-21-mini-languages/https://danielgregoire.dev/posts/2023-02-21-mini-languages/Writing small languages for enjoymentTue, 21 Feb 2023 00:00:00 +0000https://danielgregoire.dev/posts/2023-01-27-clojure-function-arity/https://danielgregoire.dev/posts/2023-01-27-clojure-function-arity/Exploration of function arity in ClojureFri, 27 Jan 2023 00:00:00 +0000https://danielgregoire.dev/posts/2021-10-15-clojure-src-test-meta/https://danielgregoire.dev/posts/2021-10-15-clojure-src-test-meta/One domain's metadata is another domain's data. What differentiates them is context. I argue in this post that we need to consider a new, additional source code context for our Clojure projects: in addition to the ubiquitous src and test folders, we need to add a meta folder.Metadata is data that describes a context in which the data it annotates bears significance beyond the unadorned sum of its parts. Notably, metadata does not define the context, but a context. Values are the universals, whereas names we give to values and collections of them establish contexts through which we begin to synthesize information from our data.Fri, 15 Oct 2021 00:00:00 +0000https://danielgregoire.dev/posts/2021-10-12-weave-pollen-for-clojure/https://danielgregoire.dev/posts/2021-10-12-weave-pollen-for-clojure/Pollen is a language and set of tools implemented in Racket that support writing documents as programs. While Pollen provides a path for non-programmers to write Markdown or HTML, for programmers, the third tutorial reveals the true power of the platform, because it reveals how to extend Pollen's default document structure to support custom nodes (tags).I have recently released a Clojure library called Weave that provides an extensible API for authoring documents in Clojure using a Hiccup-style syntax. While this library provides the API, it does not implement an output format. Thus far I have implemented a Markdown output format, which is hosted here:Tue, 12 Oct 2021 00:00:00 +0000https://danielgregoire.dev/posts/2021-06-18-open-closed-systems-clojure/https://danielgregoire.dev/posts/2021-06-18-open-closed-systems-clojure/Clojure encourages open systems.Fri, 18 Jun 2021 00:00:00 +0000https://danielgregoire.dev/posts/2021-06-13-code-observation-clojure-destructuring/https://danielgregoire.dev/posts/2021-06-13-code-observation-clojure-destructuring/Clojure's destructuring helps us establish bindings to items in Clojure collections in a concise, intuitive way.Sun, 13 Jun 2021 00:00:00 +0000https://danielgregoire.dev/posts/2021-06-05-code-observations/https://danielgregoire.dev/posts/2021-06-05-code-observations/We often gain an understanding of how a code base works by making changes to it and observing the effects.
