Ask HN: What are your favorite examples of elegant software?

I can't speak to the quality of the code base (I don't know go), but as a user caddyserver is pretty great.

I agree. The declarative/functional nature of spreadsheet formulas is certainly elegant, even if you might not say the same about Excel as an application overall. The same could be said about other spreadsheets (e.g Google Sheets).

Incredibly easy to host open source network video recorder with object tracking and hardware acceleration support. You have to install hardware and know what you're doing to hook things up, but bespoke systems that do these things cost tens of thousands for hardware/licensing alone and don't do them half as well.

It's been an absolute joy toying with TV after all this years for some TUI side-projects.

I'm a definite 'excel-apologist' and think Excel is brilliant and incredibly powerful when used correctly, so the below may be biased but...

Plenty of the other software listed has user-error misuses (For instance C is listed, and by the same standard it could be considered responsible for more software vulnerabilities than anything else!).

Sure there are errors in spreadsheets, but as the alternative is often calculating something by hand or asking similarly-trained users to write a python scripts, I think both those options probably create more errors.

Looking at the 'horror stories' listed on that website:

* The first listed is about the UK government using a version of Excel that is over 10 years old, with an issue that would not have happened if they updated the software.

* The third listed is because someone ENTERED incorrect information into a procurement spreadsheet (they copied the specification for a standard bed in rather than a critical care bed).

* The fourth is user input error - they input a fund as Dollars rather than Euros (how is this Excel's fault?)

* The fifth and sixth talk about logic errors - one with hard-coding a value and another with using 'cumulative mileage totals rather than running calculations on a sample average for vehicles'.

I agree that spreadsheets can have issues, but most of these can be mitigated by setting up sheets properly and I haven't really seen a compelling replacement for a spreadsheet for the sorts of stuff it gets used for.

The real problem with spreadsheets is a lack of training - I would estimate less than 20% of users know how to turn on cell validation, less than 10% know how to write a dynamic array formula, and less than 5% know how to use PowerQuery. It's like asking a bunch of people to write python code, but only 10% of users know how to write a loop, and then we are surprised that there are issues.

Besides, if you input a fund into a fancy financial package with the wrong currency it will cause the same issues.
