I’ve read what you wrote, but you are refusing to acknowledge reality. Availability does not even remotely mean what you are stating. You might reconsider taking infosec 101.

If the Tor network has no access, then they have no availability.

Then there is no service that has any availability and all meaning is stripped from the word.

The website is not just for transmitting tax declarations.

Indeed, and if TLS isn’t sufficient for you then by all means, use the postal service. Hell, you could even go to your local IRS location.

No, you have full access. You can go utilize 100% of the functionality of the site. Again, you are misrepresenting what availability is in the CIA triad. It does not mean all feasible ways and means of access are supported. Otherwise you’re arguing that all iOS apps are also insecure because they aren’t available to Android users.

If TLS isn’t sufficient (or available) for you, do the paperwork and mail it in.

If users who should have access (e.g. US taxpayers) are blocked, there is an availability loss. Blocking Tor reducesavailability. Which by definition undermines security.

This is a gross misunderstanding of that CIA triad. You do have access, just not through tor. Nor through Bluetooth. Nor plaintext. “Availability” does not mean you will support every known protocol so that purists and idealists can be happy.

He lives in New York, you simpleton

Never too late to pick up a hobby. Can be intimidating to start exploring and trying new stuff, but it’s worth it.

Lifting weights, motorcycle, programming at home for fun and not profit.

Lifting weights is awesome. You can do it with friends, but I tend to go solo. It’s meditative and humbling. At the same time, it’s an absolute ego boost to start seeing your progress and comparing with others.

Motorcycling is a ton of fun, but quite expensive. Buying a bike is a gut punch, then all the over priced gear. You can be thrifty about it using Facebook marketplace but you’re gonna be out quite a bit of money.

I’m a software engineer at work, but I honestly enjoy programming. I have a discord bot or two that I wrote just for my discord channel with some buddies. I also run 4 raspberry pi’s at home that require occasional IT work to do their various tasks. It’s low risk and rewarding and helps keep me a little sharper at my day job.

The most obvious answer is gaming. Hard 60/144Hz deadlines is RT. But there are lots of changes that got into the kernel from the RT group, starting with getting rid of the BKL, which helped everyone.

People who wanted GPS were also already using it by buying TomToms or other GPS devices…

The average desktop user already benefits from the changes the RT folks have slowly been getting into the baseline.

“Very fast” is relative. 1200mm/s is very fast for 3D printing, no argument. But it’s 1.2mm/millisecond, and we’re talking about time scales in the microsecond range. I suspect you’re going to run into materials issues far before real time performance becomes a limiting factor in print speed and quality.

It’s like saying GPS was available for decades before, why would putting it in everyone’s phone expand its popularity.

For myself, I’m hoping the nerds and hackers that otherwise found it not worth the effort will start creating tools to manage real time better and start building them into the applications they write. That way you don’t need to pay an arm and a leg to RedHawk for the privilege of dynamically isolating CPUs or have to reboot the computer to modify kernel arguments a la RedHat MRG.

What’s preventing that from working now? If it’s indeterminate latency, then yeah, absolutely. Theoretically this will give you the ability to have a very deterministic loop around the accelerometer data, but 3d printers don’t move all that fast to begin with so having unbounded latency might not matter. The determinism we’re talking about here is on the order of tens of microseconds or less.

It’s a bad meme. Nothing wrong with the topic or fighting against sexism in academia, but the context of the picture is literally the opposite of the message.
