I'm pretty sure kids would do just fine with sticks, mud, pine cones and whatever scrap is lying around. At least mine did before they got engaged in the paychological warfare that is cartoons, toy stores and catalogs. Even now they se

While I agree with the overall sentiment, crime is usually negative sum: the perpetrator gains less than the victim lost, thus some value is destroyed even before security spending.

Luckily you shouldn't need to do those things all by yourself.

Agreed on needing better tech and the futility of trying to forcefully lower living standard. However I feel there are also choices that align with all the goals. Such as spending less on cheap disposable shit (which is so hard to do in our

I write the kind of documentation that would help me to get to know a codebase quickly. - Architecture: what modules are there, what are their responsibilities? What is in scope and out of scope (non-goals are super important). Keep this sh

In that case clang, gcc and msvc would be considered low quality conpilers. I get the sentiment: compiler bugs have a cascading effect, especially miscompiles (looking at you, clang). Crashed while compiling (looking at you, msvc) are also

JVM has first class objects, exceptions and managed memory. WASM doesn't. This does not make one better than the other, just indicates their intended uses.

Truffle works by taking your interpreter and generating a compiler by partial evaluation [1]. So I believe they have written a JVM bytecode interpreter and Truffle makes the JIT. I'm super impressed by how the Truffle/GraalVM team

I struggle a bit with the analogy of Beethoven and accessibility. By his day European music had swung from Bach's contrapuntal intricacies towards lighter playful elegance of Mozart's time. To me, Beethoven represents the start of

+1 for SML. I've found F# scratches some of that itch. It is a CLR language with all the up- and downsides that come with .net

Too bad the tone is so vitriolic, because there is an argument hidden in there somewhere. Type systems allow us to add theorems to our programs about how they operate and have the compiler check their consistency. We fight with bugs: progra

Nobody does that stuff alone. I think a more accurate description would be that he seems to be a force multiplier for the team he leads, which can have a bigger impact than any singular engineering feat.

Thanks for these! My assumption is that hiring Keller means they plan to gain advantage by world class execution rather than some crazy architectural leap of faith.

This page has some details of Tenstorrent's current chips [1]. Looks like a manycore simd design focused on tensor ops from a brief look. Apparently they also have some sort or compression scheme to boost memory bandwidth. 1: https:&#

I actually don't want to get into the argument over which is better, but dynamic and static types do change everything, also with regard to how those features in the list feel in a language.

I think it is more complicated as they will presumably also age slower, thus trade the time lost right now to gain more later. It is all too fantastical for me to speculate on the market value of that transaction.

From a device class where the newly all-important perf per watt was always the north star, in a market with the largest chip volume, by a company with ample margins and mountains of cash? Does not seem all that absurd :)

I've been updating a small codegen since the 3.x days. There have been many API changes with major versions. That said, I always found it pretty easy to implement the changes (something like a workday for my ~10k LLVM-interfacing LoC),

Clojure has transient mutable collections that are designed to become persistent once "complete". [1] Some systems have made use of using reference count of one (unique owner) as permission to mutate, something that TFA generalize

This paper is worth reading; an implementation detail that may be useful to many is their use of reference counting: negative refcount is used to indicate thread-shared objects. Releasing objects goes fast path with a single branch when ref

Worked pretty smoothly for me. Probably helped that I had some relatively good looking private sector consulting gigs during my doctorate and post doc.

Biber is a reference manager, so orthogonal to XeTeX or general unicode support.

This sounds pretty condescending to me. I've worked on C++ for a long time, including on bare metal and compilers, and yes, the abstractions are totally comprehensible. But keeping them in your headspace is a full time job. The sheer s

You can get started with the oldskool immediate mode OpenGL, which is basically just direct emission of vertices triangle by triangle.

Simple? I know it's easy to forget how much .. stuff .. there is in an imperative language. You have the side-effect in print, and if you replace that with appending a string you're going to invoke the weird and wonderful assignme

Yes, which leads to beautiful things like `LIST_SEPARATOR` [1]. Lists in CMake are just strings with ';' as item separator. All this is just a gentle slap on the wrist for programming in your build system. Or doing something weird
