AWS definitely lives above unpaid developers. In fact they should probably be the bird flying straight at the unpaid developers as they force yet another company to move to a closed license to survive.

The shark biting the cable is what gets me
The "Whatever Microsoft is doing" bit was always my favorite.
One of DNS pillars should be replaced by BGP.
I like that the hand crank is going counter-clockwise
Can someone help me understand the single brick at the very bottom under Linux? What is it representing?
The undersea cables actually connecting the entire internet. Sometimes sharks just take a bite of them, they're reasonable well protected but it's enough damage to cause outages and disruptions.<p>It's the single pin under everything because there are a limited number of those cables especially in some regions so a single shark can take out the entire internet for some countries.<p><a href="http://www.mirceakademy.com/uploads/MSA2024-6-6.pdf" rel="nofollow">http://www.mirceakademy.com/uploads/MSA2024-6-6.pdf</a>
Do satellite networks not move the needle in terms of capacity/reliability now?
Conceptually, it's the difference between your wifi versus running a single fiber to each room in your house. The difference in bandwidth is multiple orders of magnitude.<p>This is never going to change because from a physical perspective free radio is a shared medium while each individual fiber (or wire) has its own private bandwidth.
Only a little bit. Just clicking around, a new Hawaii cable is supposed to have 24 Fiber Pairs and 18Tbit per Fiber Pair at the end of this year. If you lose several tbits of bandwidth, you're going to have a hard time making it up with satellite.<p>For small island countries and such, satellite capacity may be sufficient; and it is likely helpful for keeping international calling alive even if it's not sufficient for international data. But when you drop capacity by a factor of 1000, it's going to be super messy.
No. They're not setup to be a principal route between two nations and most satellite networks until very recently didn't even route messages through other satellites but instead retransmitted them to a ground station with access to hardline internet. Even Starlink mostly does this still because it's way cheaper and easier.
I never understand why questions like this get downvoted around here.
I feel like having them as a single brick is a bit hyperbolic, since undersea cables are pretty redundant in most of the world. Get rid of one and traffic just routes around it. Ships have been routinely destroying cables in the Gulf of Finland and the Baltic Sea in the past couple of years without causing significant disruptions.
Only mildly. There's not huge amounts of dark capacity just sitting around waiting to take over so if a major fiber connection goes down the remainder will get congested with the extra capacity. It won't cascade like a power outage but the remaining lines will slow down.
The whole Internet was designed for precisely this use case. If there is an outage, the distributed system will try to find another path. No actual central point of failure. As you say, the single brick is hyperbolic. But yea, those sharks can certainly be disruptive at times.
Well that depends on how much traffic that cable was supporting, how much free capacity is available on other cables heading to the same area, how much additional latency the rerouting will add and how sensitive to latency the rerouted traffic is doesn't it?

Undersea cables. With a shark biting one.

Looks like an undersea cable to me
Oh wow! :)<p>Thank you for the laughs. I needed that!
given the events of the last few days, one could add a Shahed drone too.
I love that the thing of itself is completely unstable once you click somewhere to start the simulation … :)
Here's a little more context about the author's motivation:

> In my online undergraduate P5.js course, students are about to begin the module on motion and physics, including a bit of physics simulation using Matter.js.<p>When did things get specialized this much?
Looking through the website of the course, it's not really a general computer science course - it "explores the use of graphics in art, design and visualization contexts" and is part of the digital art program. Quite a reasonable tech stack, for that purpose I think.
Oh cool, a product of Waterloo's Craig Kaplan, most famous for his work on the discovery of the einstein monotile
Register the mousemove event handler on window, then you will still get the events when the mouse moves out of the window/frame while dragging and it won't be that buggy.
I love that the initial state itself isn't stable.<p>The world keeps moving around us. Can't choose staying still.
Interesting! It's stable on my machine. I wonder if this is due to floating-point differences.
On my machine, the initial state isn't simulated. It only begins simulation when I touch it. At which point, the weight causes the bottom blocks to intersect each other significantly.
For me, bottom blocks stay still while those on the very top fall down.
Maybe that's what I'm seeing.
One more pedantic nitpick: when a block gets wedged between two blocks at an angle, it gets slowly pushed out, although there is a lot of weight resting on the top block. That would be realistic only (maybe) if the blocks were made of ice, but not for other materials...
I‘m guessing it‘s somewhat framerate-dependent.
That's the javascript effect.
Nah that's just the effect of turning on the simulation. The initial version isn't the same as the first steps because there's no weight. If you look closely after you click the blocks overlap slightly.<p>Something similar happens all the time in games when you go from a static version of something to the higher level of detail version with physics enabled, if the transition isn't handled gracefully or early enough you can get snapping.
Just like real life. Sit still, touch nothing, and watch everything fall apart all on its own ¯\_(ツ)_/¯
I love that clicking the empty space and just doing nothing at all <i>still</i> causes the blocks to fall apart after some time.
love it, integrate it into <a href="https://github.com/matzehuels/stacktower" rel="nofollow">https://github.com/matzehuels/stacktower</a> please!
oh look at that. removing IBM enterprise apps really doesn’t break anything and the whole stack got lighter. science.
Did you actually manage to remove a block without everything collapsing (eventually)? Then you must have an incredibly steady hand, it's nearly impossible to do as far as I can see. Which can also be interpreted as a metaphor for the state of the tech stack, I guess...
This is wonderful.<p>The gravitational constant is maybe a little low for my taste, but I like that I can fling a block vertically up off the top of the frame and it reappears even 5+ seconds later. Things don't get ignored out of existence. Neat.
As entropy increases, the stack rises.<p>But then, when trapped in a local maxima prohibiting growth, pressure builds as too many new layers attempt to shim themselves under existing layers, until inevitably the stack collapses somewhere.<p>Then new layers can restart generating new apex baby layers on a now higher foundation of fertile fragmented but compressed and stable new-legacy rubble. Another point-oh age begins.<p>And sometimes, the stack just falls apart because.<p>In between those extinction events, layers that spawn the most layers, and form opportunistic bridges over lateral layers, dominate and thrive.<p>Occasionally, some layers try to reorder themselves to optimize future growth. Or tunnel down to achieve stronger footing. But like the tower of Hanoi, the more layers involved, the more intractable the replanting and reordering. Meanwhile, other growth routes around them. Yet, many instances of these failed structures can be found in the depths.
If you just let the simulation fall apart under its inherent instability, the thanklessly maintained project is often one of the last things to fall. That seems poetically correct.
This is oddly fun to play with. Has that angry birds vibe
this is the best thing internet since the last best thing in the internet
Too delightful. Like a reverse jenga tower you like to topple over.<p>Of course, glad to see it was another @isohedral project.
I would add some lerp-smoothing to the position of the cursor/touch, since it's a bit rigid. Click-drag-release often doesn't result in a fling but rather a sharp drop.<p>Lovely idea by the way.
The physics remind me of Little Inferno
without touching the block, after a while it begins collapsing, which makes it an even better representation of infrastructure
Very satisfying. I ripped out the load bearing piece and everything stayed standing except for the tiny pieces at the very top. Doesn't seem so bad according to the simulations, maybe we could use a good shakeup?
Challenge: Rearrange the blocks into a stable configuration without losing any offscreen
Just to mention the original was cited in the most recent Veritasium video:<p>"The Internet Was Weeks Away From Disaster and No One Knew"<p><a href="https://www.youtube.com/watch?v=aoag03mSuXQ" rel="nofollow">https://www.youtube.com/watch?v=aoag03mSuXQ</a><p>(at about the 9:50 mark)

Really cool! To be honest, when I clicked on this I had a hope that it would be possible to add things to the stack like the ongoing memes of just putting different things in there (maybe live with other people as a collaborative editor).
It looks like the stroke/border is not taken into account in the physics simulation.
That was a lot of fun actually. I used one block to wreck all the others. Thanks for sharing.

I was expecting it to open the FFmpeg website at the end.
I would like to have online multiplayer version of Jenga game based on these mechanics
Played with it on the phone. So satisfying.<p>I know the time it takes to get something to feel this good.<p>Really fantastic work.
Liked those small Box2D playboxes from decades ago, wonder where all that went.
On an unrelated note, AI completely changed economics of <a href="https://xkcd.com/1205/" rel="nofollow">https://xkcd.com/1205/</a><p>Previously I'd postpone some tooling since I'd lost more time on it (unless it's something I wanted to learn anyway), but now I'm all in.
It's like open source Angry Birds.
I knew exactly what this would be before even clicking it. Someone had to make it!
It's adorable. One small criticism: instead of being stored as initial conditions with no internal forces, if the tooling allows for it it should be stored as the "relaxed" state with internal forces. As it stands, the first interaction with it causes the whole model to 'bump' because everything is actually just kinda hovering in space with no physics simulation happening and only the first interaction causes physics calculations to start.
We absolutely need a "whatever Microsoft is doing" object in that.
Increase friction
I hope Randall reads HN and sees this, he’d love it.
Is this website intended to break HN on Android? I've never had a website lock up the HN app like this. I couldn't back out, and I was stuck in a loop when the app restarted on the same page.
Who are the big blocks that survive the collapse though?
Ooooh, that's fun to make topple. I kind of want to launch an Angry Bird at it.
needs angry birds version<p>or not, it’s great as is BTW
Feature request - be able to change the text and re-share it.<p>Half the fun of this xkcd is referring to it in context of whatever just went haywire.
It'd be really cool (and probably useful) if someone could figure out a way to generate diagrams like this for any software project.<p>You'd first need to figure out a way to generate a complete dependency tree. For each box, I interpret its height as a measure of its complexity and its width as a measure of the support it receives. The hardest part would probably be figuring out a way to quantitatively measure those values.
One naiive solution could be to cloc the dependency and use the size as the height, and fetch number of github contributors as width
Ask and you shall receive: <a href="https://stacktower.io/" rel="nofollow">https://stacktower.io/</a>
Oh cool. That's a promising start.<p>I don't know if the "The Nebraska Guy Ranking" this project uses is very useful, though. In particular the "depth" criteria doesn't make much sense to me, since it assumes the more foundational a dependency is, the more robust it must be. This seems to run counter to the point of the original comic where the "Nebraska Guy" piece was the fragile block holding up the entire tower.<p>This project also doesn't attempt to measure or visualize the complexity of a project. Theoretically a more complex project would require more support than a simple one, so I think that's an important metric to capture.
bro. it asks for the ability for some random github user to literally take over your private repositories.
You’re 100% right to call that out. The current GitHub OAuth scope is too broad<p>I’m changing this ASAP to least-privilege and I’ll publish a clear explanation of scopes + data handling. In the meantime: please run the local/CLI path if you want zero-trust.
Yeah, if it weren't for that, I think this would blow up. Plus, even if you get past that, if you try a larger project, it times out after 1 minute and gives up. But it's a pretty awesome idea!

I think you may have set friction too low
THIS IS THE BEST THING EVAR!
Now we just need a generated version of this based on a package.json!
I'd like a medal for clearing the screen of all debris. What's that you say, some of it is still useful? oh
If only it wouldn't collapse by itself after clicking anywhere (clicking seems to activate physics) this would be 10/10
> If only it wouldn't collapse by itself after clicking anywhere (clicking seems to activate physics) this would be 10/10<p>I think that's the other metaphor here.<p>It's not just standing on the tiny shoulders of one forgotten maintainer. The entire system only appears stable because we're looking at a snapshot of it.<p>In reality it's already collapsing.
And that tiny thing is actually one of the last to collapse...
Yeah. Seems like there is ~0 friction.
The blocks feel a little bit too slippery
funny, but poorly coded because there's not friction coefficient it seems - just clicking into the applet, everything eventually just falls over
No title text, No respect...
This is very real.
What’s the Nebraska project?
epic
the weird physics are mildly infuriating. still funny though
