Security can mean security against hackers, but it can also mean security against revealing classified information. Classified information about weapons systems (e.g. performance characteristics) is inherently embedded into the code running on those systems, and therefore shouldn't be open sourced.

Source: used to write classified code

Unless it's maintained it won't be of much use. It needs to be kept up to date with tax laws, and it relies entirely on the IRS accepting the generated returns. It seems it may function for now, though.

Direct File interprets the United States' Internal Revenue Code (26 USC) as plain language questions, the answers to which should be known to taxpayers without need of external instructions or publications. Taxpayers' answers are then translated into standard tax forms and transmitted to the IRS's Modernized e-File (MeF) API, which is available for authorized public use

Linux geeks, assemble!

TurboTax owned buy intuit, part of H&R block who has partnered with credit karma. Everything is a monopoly now

A lot of functionality can be decoupled from anything that needs to be classified. A HUD is a HUD and no one should be hard coding in performance characteristics of the F-35 into it. I've also worked on government projects and holy crap does the code quality vary wildly, even before you get into "it's still working so deal with the problems, it doesn't have the budget for updates".

Using 'off the shelf' parts/code can save significant time and money. There's a reason subs use xbox controllers. Government websites and data interfaces at the very least should have the audit-ability that open source provides.

I'm sure there are exceptions for classified systems. Personally, I do believe all things developed by tax payer money should be released to the public including classified systems, given enough time has passed that the release of such information wouldn't put anything or anyone at risk.

A HUD is a HUD

sure but the HUD from the F-35 is very specifically designed to work in an F-35. It's very similar, and comes from the same family, as the software running on other planes. But it's not identical.

And yes, performance limits would be hard coded into the software because the HUD needs to alert the pilot when they are getting close.

Edit: and that's ignoring the fact that a lot of this stuff comes from private companies so you'll run into things like IP/patent laws

For the most part they are. You can find enormous troves of classified documents that have been made public, and a huge amount of once top secret technology and engineering eventually makes its way into the public space.

Direct File is maintained by the IRS themselves though.

You are correct.

Here's an annoying thing i just learned about H&R Block:

As of 2022, H&R Block's tax preparation service shares user data with Facebook, which can be used for targeted advertising. This can include sensitive financial information from health savings accounts and college expenses, and this tax data is shared without consent even for users who opt out of the service.

We've already got free software for filing taxes, kthxbye!

Yeah I saw Monopoly Fortnite I wonder what is next?

Perhaps i should have said hot, but seriously; more fun to not.

So you're saying he's really really ugly
