Energy-Languages VS ts-node

Looking at the benchmark where C++ is worst compared to other languages, it's depending on the library used. I would guess if they used Google's re2 Regex library instead of Boost's, the result would be different.

Trawling through the wayback machine, I did find that the older pages link to https://github.com/greensoftwarelab/Energy-Languages, which does seem to provide the contents of the specific programs used and the benchmarking software. Excellent.

> … not … primarily an issue with means vs medians

We're comparing averages, why would we bother so much about the cause of an outlier.

> you linked directly to the C++ code for spectral-norm

You had linked to the wrong C and C++ code for spectral-norm, I linked to the code that was actually used.

> The time ratio of the Benchmarks Game fastest C version to the slowest C++ version is over 16x.

Again, you seem to be looking at the wrong repo.

The authors of "Energy Efficiency across Programming Languages, SLE’17" provided this repo —

The paper authors provided a repo for the source code they used: https://github.com/greensoftwarelab/Energy-Languages

The study made their own measurements. They did not re-use measurements made by the benchmarks game.

One of the JavaScript programs at least was concurrent, whereas the TypeScript equivalent was synchronous. No wonder there's a difference...

Haven't looked closely at the other problems, but it's apparent to me that the solutions are not even trying to be similar, so comparing their efficiency is near useless.

the problem in question was the k-nucleotide one, IIRC:

I've been trying to replicate a study on energy usage (alright, it's that study on energy usage) and I've hit a bit of a snag while trying to compile the Rust components of the project. Instead of using a Cargo.toml and building with cargo, the authors have decided to use a Makefile and manually pass flags into rustc.

Here is an issue from the repo with the code they used: https://github.com/greensoftwarelab/Energy-Languages/issues/34

I thought this was going to be a project like ts-node [1]

The command specified in the app option uses ts-node by default, which is an execution engine for Node.js that allows you to run TypeScript code directly. The --prefer-ts-exts flag prevents ts-node from prioritizing precompiled .js files and will always import the TypeScript source code instead, if it is available. This is useful if you are also using tsc (the TypeScript compiler) alongside the app option. The bin/cdk.ts file is the entry point for our CDK app, which defines the main function that will be executed when the app is run.

If you want to write apps that run on Node.js I would suggest using Google’s TypeScript style guide. You can start using it by simply running npx gts init. I’d suggest that you start with this and run your apps using ts-node/ts-node-dev because it does not require an extra build step.

ts-node (“TypeScript execution and REPL for Node.js”)

Here is a relevant discussion and dev comment: https://github.com/TypeStrong/ts-node/issues/155

It does support ESM, with a --loader[1], but even with its SWC option it’s still significantly slower than the esbuild loader I’m working on. Unfortunately, esbuild isn’t totally compatible with tsc, so it’s not a drop-in replacement without plugins.

The process of compiling TypeScript source files into JavaScript code before executing them with Node.js can get a little tedious after a while, especially during development. You can eliminate the intermediate steps before running the program through the ts-node CLI to execute .ts files directly. Go ahead and install the ts-node package using the command below:

I tried suggested solution by https://github.com/TypeStrong/ts-node/issues/1007 but this causes problem with NestJS decorators:
