Mathematics and Computation | How to implement dependent type theory I
How to implement dependent type theory I 08 November 2012 Andrej Bauer Type theory, Programming, Software, Tutorial I am spending a semester at the Institute for Advanced Study where we have a special year on Univalent foundations. We are doing all sorts of things, among others experimenting with type theories. We have got some real experts here who know type theory and Coq inside out, and much mo
The look of music — Harvard Gazette
When it comes to classical music competitions, one could be forgiven for thinking how well someone plays is the single most important factor. New research conducted by a recent Harvard graduate, however, suggests otherwise. In a study by Chia-Jung Tsay, who last year earned a Ph.D. in organizational behavior with a secondary Ph.D. field in music, nearly all participants — including highly trained
What's happening in Go tip (2013-08-23) — Dominik Honnef
Published: Friday, August 23, 2013 Last modified: Sunday, January 15, 2023 by Dominik Honnef Last week I published the first article in an ongoing series on changes in Go tip. It was met with a lot of positive feedback, so here’s the second article. Thank you for your support and I hope you enjoy this article just as much as the previous one. What’s happening ¶ This time we’ll be looking at: A new
Promises/A+ - understanding the spec through implementation
NB: This is for promises/A+ v1. The spec has since moved to v1.1. The below is still a good introduction. There are now slides available with an implementation of v1.1. What we're going to do is create a promises/A+ implementation based on http://promises-aplus.github.io/promises-spec/. By doing this hopefully we'll get a deeper understanding of just how promises work. I'll call this Aplus and put
Julia Introspects | Leah Hanson
When people are introspective, they’re thinking about how their minds work, about how and why they think what they do. The Julia language has some impressive facilities for letting you see how the compilers’ mind works. Using convenient built-in functions that are available both at the REPL1 and in normal code, Julia allows you to see the layers of internal representation that your code goes throu

apfelmus - Reasoning about space leaks with space invariants
Recently, the unordered-containers library has included some changes that made a function much more strict than is sensible in a lazy language like Haskell. The changes were meant to improve consistency on a performance-related issue, namely whether the container should be “key-strict” or “value-strict” or some combination thereof. However, I think that the recent blooper is a sign that there is a
What's new in Cabal 1.18 — sandboxes, REPL, cross-compilation and more!
The 1.18 release of Cabal is almost ready. This post describes what’s new and improved in this version. User-visible features Sandboxes - isolated environments for building packages, similar to (and inspired by) what the popular cabal-dev tool provides. See this article for a more detailed introduction. cabal repl - New command that opens an interpreter session for the given target (executable or

Using C Dynamic Libraries In Go Programs
August 20, 2013Using C Dynamic Libraries In Go Programs My son and I were having fun last weekend building a console based game in Go. I was recreating a game from my youth, back when I was programming on a Kaypro II. I loved this computer. I would write games in BASIC on it all day and night. Did I mention it was portable. The keyboard would strap in and you could carry it around. LOL. But I digr
Go のチュートリアルに足りないこと - Cybozu Inside Out | サイボウズエンジニアのブログ
ちょうど今日から夏休みの @ymmt2005 こと山本泰宇です。こんにちは。 夏休みなのにブログを書いている点は突っ込まないでください。 今回は Go を初めて業務に使ったときに躓いた点をまとめた資料を紹介します。これから使いだそうと考えている方は、これを読めば１日分位の調査は省けるかと思います。 ご存知の方も多いと思いますが、Go は Google で C++ が従来担当していたシステム開発用の言語として開発され、2009 年に公開されたプログラミング言語です。ここ最近広く使われだしたようで、一昨日の Hacker News では Go の記事が乱立していました。 cybozu.com でも Go を開発言語のひとつに採用しようとして、まず Python で書かれていたある TCP のクライアント・サーバープログラムを Go で書き直してみました。型どおりに公式のチュートリアルをこなし、
