<span class="Comment">;</span>
<span class="Comment">;   &quot;Is it a language, or an operating system, or a virtual machine? Mu.&quot;</span>
<span class="Comment">;   (with apologies to Robert Pirsig: <a href="http://en.wikipedia.org/wiki/Mu_%28negative%29#In_popular_culture">http://en.wikipedia.org/wiki/Mu_%28negative%29#In_popular_culture</a>)</span>
<span class="Comment">;</span>
<span class="SalientComment">;; Motivation</span>
<span class="Comment">;</span>
<span class="Comment">; I want to live in a world where I can have an itch to tweak a program, clone</span>
<span class="Comment">; its open-source repository, orient myself on how it's organized, and make</span>
<span class="Comment">; the simple change I envisioned, all in an afternoon. This codebase tries to</span>
<span class="Comment">; make this possible for its readers. (More details: <a href="http://akkartik.name/about">http://akkartik.name/about</a>)</span>
<span class="Comment">;</span>
<span class="Comment">; What helps comprehend the global structure of programs? For starters, let's</span>
<span class="Comment">; enumerate what doesn't: idiomatic code, adherence to a style guide or naming</span>
<span class="Comment">; convention, consistent indentation, API documentation for each class, etc.</span>
<span class="Comment">; These conventional considerations improve matters in the small, but don't</span>
<span class="Comment">; help understand global organization. They help existing programmers manage</span>
<span class="Comment">; day-to-day operations, but they can't turn outsider programmers into</span>
<span class="Comment">; insiders. (Elaboration: <a href="http://akkartik.name/post/readable-bad">http://akkartik.name/post/readable-bad</a>)</span>
<span class="Comment">;</span>
<span class="Comment">; In my experience, two things have improved matters so far: version control</span>
<span class="Comment">; and automated tests. Version control lets me rewind back to earlier, simpler</span>
<span class="Comment">; times when the codebase was simpler, when its core skeleton was easier to</span>
<span class="Comment">; ascertain. Indeed, arguably what came first is by definition the skeleton of</span>
<span class="Comment">; a program, modulo major rewrites. Once you understand the skeleton, it</span>
<span class="Comment">; becomes tractable to 'play back' later major features one by one. (Previous</span>
<span class="Comment">; project that fleshed out this idea: <a href="http://akkartik.name/post/wart-layers">http://akkartik.name/post/wart-layers</a>)</span>
<span class="Comment">;</span>
<span class="Comment">; The second and biggest boost to comprehension comes from tests. Tests are</span>
<span class="Comment">; good for writers for well-understood reasons: they avoid regressions, and</span>
<span class="Comment">; they can influence code to be more decoupled and easier to change. In</span>
<span class="Comment">; addition, tests are also good for the outsider reader because they permit</span>
<span class="Comment">; active reading. If you can't build a program and run its tests it can't help</span>
<span class="Comment">; you understand it. It hangs limp at best, and might even be actively</span>
<span class="Comment">; misleading. If you can run its tests, however, it comes alive. You can step</span>
<span class="Comment">; through scenarios in a debugger. You can add logging and scan logs to make</span>
<span class="Comment">; sense of them. You can run what-if scenarios: &quot;why is this line not written</span>
<span class="Comment">; like this?&quot; Make a change, rerun tests: &quot;Oh, that's why.&quot; (Elaboration:</span>
<span class="Comment">; <a href="http://akkartik.name/post/literate-programming">http://akkartik.name/post/literate-programming</a>)</span>
<span class="Comment">;</span>
<span class="Comment">; However, tests are only useful to the extent that they exist. Think back to</span>
<span class="Comment">; your most recent codebase. Do you feel comfortable releasing a new version</span>
<span class="Comment">; just because the tests pass? I'm not aware of any such project. There's just</span>
<span class="Comment">; too many situations envisaged by the authors that were never encoded in a</span>
<span class="Comment">; test. Even disciplined authors can't test for performance or race conditions</span>
<span class="Comment">; or fault tolerance. If a line is phrased just so because of some subtle</span>
<span class="Comment">; performance consideration, it's hard to communicate to newcomers.</span>
<span class="Comment">;</span>
<span class="Comment">; This isn't an arcane problem, and it isn't just a matter of altruism. As</span>
<span class="Comment">; more and more such implicit considerations proliferate, and as the original</span>
<span class="Comment">; authors are replaced by latecomers for day-to-day operations, knowledge is</span>
<span class="Comment">; actively forgotten and lost. The once-pristine codebase turns into legacy</span>
<span class="Comment">; code that is hard to modify without expensive and stress-inducing</span>
<span class="Comment">; regressions.</span>
<span class="Comment">;</span>
<span class="Comment">; How to write tests for performance, fault tolerance, race conditions, etc.?</span>
<span class="Comment">; How can we state and verify that a codepath doesn't ever perform memory</span>
<span class="Comment">; allocation, or write to disk? It requires better, more observable primitives</span>
<span class="Comment">; than we currently have. Modern operating systems have their roots in the</span>
<span class="Comment">; 70s. Their interfaces were not designed to be testable. They provide no way</span>
<span class="Comment">; to simulate a full disk, or a specific sequence of writes from different</span>
<span class="Comment">; threads. We need something better.</span>
<span class="Comment">;</span>
<span class="Comment">; This project tries to move, groping, towards that 'something better', a</span>
<span class="Comment">; platform that is both thoroughly tested and allows programs written for it</span>

<span class="Comment">;   If Denis Ritchie and Ken Thompson were to set out today to co-design unix</span>
<span class="Comment">;   and C, knowing what we know about automated tests, what would they do</span>
<span class="Comment">;   differently?</span>
<span class="Comment">;</span>
<span class="Comment">; To try to impose *some* constraints on this gigantic yak-shave, we'll try to</span>
<span class="Comment">; keep both language and OS as simple as possible, focused entirely on</span>
<span class="Comment">; permitting more kinds of tests, on first *collecting* all the information</span>
<span class="Comment">; about implicit considerations in some form so that readers and tools can</span>
<span class="Comment">; have at least some hope of making sense of it.</span>
<span class="Comment">;</span>
<span class="Comment">; The initial language will be just assembly. We'll try to make it convenient</span>
<span class="Comment">; to program in with some simple localized rewrite rules inspired by lisp</span>
<span class="Comment">; macros and literate programming. Programmers will have to do their own</span>
<span class="Comment">; memory management and register allocation, but we'll provide libraries to</span>
<span class="Comment">; help with them.</span>
<span class="Comment">;</span>
<span class="Comment">; The initial OS will provide just memory management and concurrency</span>
<span class="Comment">; primitives. No users or permissions (we don't live on mainframes anymore),</span>
<span class="Comment">; no kernel- vs user-mode, no virtual memory or process abstraction, all</span>
<span class="Comment">; threads sharing a single address space (use VMs for security and</span>
<span class="Comment">; sandboxing). The only use case we care about is getting a test harness to</span>
<span class="Comment">; run some code, feed it data through blocking channels, stop it and observe</span>
<span class="Comment">; its internals. The code under test is expected to cooperate in such testing,</span>
<span class="Comment">; by logging important events for the test harness to observe. (More info:</span>

<span class="Comment">; The common thread here is elimination of abstractions, and it's not an</span>
<span class="Comment">; accident. Abstractions help insiders manage the evolution of a codebase, but</span>
<span class="Comment">; they actively hinder outsiders in understanding it from scratch. This</span>
<span class="Comment">; matters, because the funnel to turn outsiders into insiders is critical to</span>
<span class="Comment">; the long-term life of a codebase. Perhaps authors should raise their</span>
<span class="Comment">; estimation of the costs of abstraction, and go against their instincts for</span>
<span class="Comment">; introducing it. That's what I'll be trying to do: question every abstraction</span>
<span class="Comment">; before I introduce it. We'll see how it goes.</span>

<span class="Comment">; Even though our memory locations can now have names, the names are all</span>
<span class="Comment">; globals, accessible from any function. To isolate functions from their</span>

<span class="Comment">; variable called default-space. When you initialize such a variable (likely</span>

<span class="Comment">; locations as offsets from its value. If default-space is set to 1000, for</span>

<span class="Comment">;</span>
<span class="Comment">; 'default-space' is itself hard-coded to be function-local; it's nil in a new</span>
