Or Microsoft Office...

Or Linux distro's.

Or BSD distros.

These are actually trivial and silly examples. The bulk of really valuable commercial code is not self contained or portable like those.

Where is the torrent with a runnable copy of paypal, or amazon?

I guess you have never compiled a Linux/BSD distribution from scratch and supported it alongside its infrastructure and lead its maintenance process.

Even without that, if you want downloadable and runnable software platforms, look to public Git repositories. Some of the people who have no financial motivation will release what they do alongside installation procedures and quality of life scripts and architecture documentation.

Most of the open source platforms doesn't publish this documentation and doesn't make installation easy to keep a sizeable moat and protect the platform they have developed, hence this is why we have a division between "Free Software" and "Open Source".

In short, "The bulk of really valuable commercial code" is self contained, but not open source, or if open source it's not Free Software and made deployable for other parties. Otherwise it loses monetary value in the eyes of the people who develop that for the monies.

Otherwise we have have Elasticsearch incident, where they pivot and move to "Source Available" model to protect their castle.

"I guess you have never compiled a Linux/BSD distribution from scratch"

You guess, and so perhaps do other things as well, with poor acuity.

The incalculable value of open source software has approximately no bearing on this assertion.

Yes I love linux and bsd too I'm not defacing your religion. I'm actually quite Stallmanesque in making my own life harder by only using ooen source software as much as possible and being super fun a family gatherings talking about it.

You sure nailed that one.

Nice, it makes us two tech leads then.

Heh, on that note:

Looking down that page, there are some valid magnet links.

Or a car

But you wouldn't download one. Would you?!?

Not yet.

It's treason then.

Where s the download link?

Or a copy of Windows or Office source code.

I don't think that's right - even if you had the full source code for either of those, it's extremely unlikely you'd be able to build them on your own machine.

Building them would be a challenge, but probably not impossible. I’ve worked on a couple of C++ projects at a similar scale to Windows (millions of LOC) and the build systems were a major pain. But a determined engineer with the readme file and no other help could get it building in a week or so.

(This probably says more about how hard it is to build C++ than anything else)

I don't really think it is a language ting, just more of a project size thing.

Well, it kind of is a language thing. Many newer languages (Rust and Go come to mind) are much more consistent in the way you interact with them as your project scales.

Some years ago someone that worked at Microsoft told me he didn't think any individual engineer who already works on Windows could ever get Windows building by themselves with just the code.

That just shows their bias. If the code is complete, it's only a matter of time to figure out how to build it.

May not take hours, but determined engineer should be able to figure it out.

I think you're being naive. Microsoft has spent 1000s of engineering years on their build system. You aren't going to just replicate that in a week.

You’re also not trying to get a full CICD pipeline complete with unit/integration tests, crypto signatures, ability to flip features on and off with a click , monitoring of the cicd pipeline, scaled so 1000s of engineers can work at once etc

As a user said below, you wouldn't need cross platform support, incremental builds, tests to run, etc.

Just getting the code to compile, link, baking in assets, etc. For a single architecture is a much more reasonable goal.

I'd imagine it'd be on the scale of 1-3months for an engineer to get working full time, but large error bars around this figure

Plus it already has been done before with Windows XP, without even any documentation and there is a guide on the internet on how to build Windows Server 2003.

This was done (if I remember right) when governments and big customers had access to the Windows source-code.

Microsoft uses Azure DevOps for products as large as Visual Studio.

> But a determined engineer with the readme file and no other help could get it building in a week or so.

That's probably true, but I wouldn't be surprised if something like windows doesn't have a README file. And it does have build instructions they may well be in some wiki separated from the source code.

Fwiw C++ is hard to build specifically, but any large project with assets is a challenge to build.

Video games build systems are a thing onto themselves even taking the c++ issues out of the equation.

Hell even comparatively simole microservices in modern CRUD apps have resorted to docker to do away with pains of rebuilding stuff.

there's 99% complete leaked windows xp source code that people have managed to compile

There are even nice timelapse videos of that process: https://vimeo.com/464644850 (you’ll need a Vimeo account to see it, because Vimeo is weird like that. This was on YouTube originally, but it was taken down.)

I think the comparison is windows ISO image, not the source code. Code used to train LLAMA is open source, but it still requires money to use that.

More like a compiled version of Windows.
