I wish there was more written in the readme about the motivation for this project.

Good point! I'll have to add that in at some point after the holidays.

My motivation was entirely that I thought this was both a hilariously stupid use of a space station's telemetry stream, but also kind of amazing at the same time. Also a great excuse to learn Swift, but the sheer ridiculousness was what drove me.

Like I said in my earlier Show HN post on this (I think? Or maybe on Bluesky), it's remarkable that we live in a world where it takes an afternoon to bang out a joke application that reads actual realtime telemetry data from a space station's toilets.


I enjoy that you learned how to use Swift in some new ways, including the MacOS menu bar. This is a perfect practice project, it seems.

Knowing the status of the ISS piss tank is its own reward.

See, you get it.

I wonder how many amazing things put there died a crib death because the creator struggled to find a "real" motivation for it's existence.

I reckon more often than not "because I wanted to" is more than enough for many things.


I expected to see a CoC in the repo.

I mean,

> Not the epitome of good coding practices since this was my first Swift & macOS app ever, may break in exciting ways at the slightest excuse.

sounds like it's a learning exercise. One of my first interesting programs was a weather app; this is just a weirder version of that.


I tried it for engineering calculations. It'll give you numbers, with the right units, but often times they are the wrong numbers.

Agreed, but I'm still learning it all, and it does a great job defining my curriculum.

Even if you didn't have to move it, getting a taxi to some meeting place would exceed the interest payments, let alone traveling to Europe.

For those like me that didn't know

"The Legal Entity Identifier (LEI) is a reference code — like a bar code — used across markets and jurisdictions to uniquely identify a legally distinct entity that engages in a financial transaction."


How do you cook food?

It's not hard to cut out the exposure listed in the comment with a little effort and time, except for the steel thing which is a bit over the top.

it’s actually needed, see lucky fish: https://en.m.wikipedia.org/wiki/Lucky_iron_fish

Debatable efficacy.

Cast iron pots and pans

Not concerned about the chromium and vanadium present in most cast iron?

I'm not deeply into that topic, but the pan I use that's made of iron was 'burned-in' using linseed oil several times to create a non-sticky surface. Whatever that has as negative side-effects aside, that layer might trap the iron additives quite effectively.

Also, glass Pyrex Tupperware.

Steel and glass

Again? Intelligence people are sleeping on the job if they're not scraping those forums all day every day.

I really doubt there’s anything meaningful coming out of these documents. It’s not going to change any literally a single country spends their military budget

I don’t think anyone is concerned about budgets. Having intimate details into the systems of these craft and understanding how they operate in great detail makes it much easier to 1. Copy it, 2. Defend against it, 3. Find critical vulnerabilities in its design, 4. Build offensive systems that take advantage of any shortcomings, 5. Fast tracks their own jet fighter programs (which to your point does affect budgets because someone else had paid for the R&D)

The same is true for any IP/competitive advantage.

It’s funny how in our industry security through obsecurity is a thing we avoid, but other industries are literally built on the foundation of hiding information in order to stay ahead


We avoid it because there are better ways, not because security through obscurity isn't security. Sometimes, obscurity is all you have.

Also because so much of software is uniquely poorly suited to obscurity. Attackers will often be able to probe the "obscure" system at their leisure trying to reverse it, or in non-SAAS cases get their hands on the actual (compiled) algorithm itself. And once you figure it out every single copy works exactly the same.

It's not like trying to measure the penetrating capabilities of a tank round, where you need physical access to a batch of large, expensive, explosive, tightly controlled objects to figure it out.


Everything is open source* if you know assembly, so to speak.

Edit: *source available


At least some classified stuff is well known to other country's intelligence services, friend, neutral, and foe. It can be so far out of the bag, it's had kittens.

Lot of stuff is classified not because it would actually prevent other nations from finding out stuff, but to hide from the American people and press embarrassing things like how much money is being spent on that particular project or weapons system, how much of a failure it has been, how much toxic waste is being created in its manufacture, and so on.

There's also all the stuff Internet Armchair Intelligence Officers think is "sensitive" or "classified."


China has access to all of our tech leaks, and yet, they cannot replicate it, neither can Russia, heck Russia has these really powerful jet planes... but they got less than a handful of them, and their GDP is comparable to the state of Florida's GDP.

> yet, they cannot replicate it, neither can Russia, heck Russia has these really powerful jet planes

Russia has powerful Soviet-era planes. Their new kit is demonstrably crap, being unable to establish even air supremacy against a foe wielding handfuls of decades-old air defence equipment.

There is also a P != NP difference between replicating a war machine and reverse engineering it sufficiently to defeat it, e.g. designing a radar that mitigates its stealth.


I can confirm, as someone who collects Soviet era electronics and buys replacement parts. Russian manufacturing is really bad now and very far from what it was during the Soviet era. Perhaps in part because of past cooperation between various countries of the communist block that is no longer there. For example Belarus and Poland made a lot of the integrated circuits(chips) back then. There are certain items, for example military radios like the R-140M almost every country had a local version of. For example the Russian version still used a vacuum tube as a delay timer well into the 80s while the Polish version had a box of digital logic.

Can I ask how you even got into such a thing?

Just get a HAM radio license :)

I just really doubt this when it comes to China.

Betting against China being able to build anything at this point seems pretty dumb.

Almost delusional I would say.


Why? Have you not seen how low quality the things they build are? Among gun collectors, Chinese made guns are considered a fat joke, unreliable. Guns of all things, they invented gun powder!

Then there's buildings, literally fall apart out of nowhere. Their standards of building things are very shockingly bad. There is no motivation to do high quality work.

There was the hospital they built during COVID that collapsed after 3 months.


Those problems aren't limited to China. Just look at the crumbling infrastructe of the 'west'. Besides that they do produce high-quality stuff, even if only specified to that level by 'western' investors/corporations.

To a large extent China has been able to replicate.

China has faced less strict sanctions and has been able to engage in much more aggressive academic and industrial espionage than post-Soviet Russia. It remains to be seen whether, now that sanctions have ramped up, and access to Western/Japanese research and expertise is being curtailed, they can maintain what they've already replicated, never mind build on it to make newer and better things.

China simply outspends russia a hundred times over. When you account for china's full security budget it's almost the same as US defense spending when accounting for PPP.

China is also the world's factory and many components of modern weapons are dual use goods of which China is the supply chain. The problem that no one dares speak is that there is no wholly domestic supply chain for most electronics and other components anymore. If war were to break out with China US defense production would halt immediately.


There is one meaningful thing coming out of these documents; WarThunder has become a reliable form of education in “how to evaluate information distribution restrictions regarding militarily-applicable topics” for the generations that grew up without the events of PGP / ITAR fresh in mind.

It’s probably some other intelligence agency leaking it.

"we aim to tackle the challenges of scalability, usability, and proof (Mathematics) automation in the Lean proof assistant."

It wouldn't be in orbit of the sun anymore

It doesn't follow, faulty logic. The two are probably correlated though.

It is actually pretty stupid to try to recover things.

I knew a guy that tried to stop someone from stealing his neighbor's car stereo.

He was extremely fit, young, and a fighter.

That didn't stop him from getting stabbed to death by the thief.

You can decide your life is worth a $100 car stereo, but I know mine is worth more than that.
