Can someone help me understand the single brick at the very bottom under Linux? What is it representing?

rtkwe6 days ago

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.

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.

http://www.mirceakademy.com/uploads/MSA2024-6-6.pdf

Hamuko6 days ago

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.

dijit6 days ago

"most of the world" is doing a seriously large amount of heavy lifting in this sentence.

There are many regions that are served by a single line, more than you think.

Even "well connected" places have fewer cables than you expect, and the frustrating thing is that you don't know that you can route around an issue until you try.

BGP is really resilient, which is great, but if your path is not clear then you'll only realise it when the failover doesn't happen, you'll think there's a redundant path.

rtkwe6 days ago

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.

drob5186 days ago

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.

rezonant6 days ago

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?

Do satellite networks not move the needle in terms of capacity/reliability now?

fc417fc8026 days ago

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.

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.

toast06 days ago

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.

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.

rtkwe6 days ago

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.

rtkwe6 days ago

You can see an unofficial tracker [0] of the Starlink downlink network and see how outside of some rural areas your data is only moving a few tens of miles away most of the time before it's sent down to a ground system. Their sats have 3 200 Gbps laser communicators for intra constellation routing which is pretty small for the task of replacing fiber optic links.

Interesting! It's stable on my machine. I wonder if this is due to floating-point differences.

andai6 days ago

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.

FireInsight6 days ago

For me, bottom blocks stay still while those on the very top fall down.

Hamuko6 days ago

If I open it, click on the background to activate the physics and just keep the tab open, pretty much all of the blocks that can collapse do eventually collapse.

smikhanov6 days ago

The Nebraska guy’s block remains surprisingly stable, even when the whole thing above it collapses. Very symbolic.

rob746 days ago

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...

rtkwe6 days ago

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.

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.

CivBase6 days ago

It'd be really cool (and probably useful) if someone could figure out a way to generate diagrams like this for any software project.

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.

TonyStr6 days ago

One naiive solution could be to cloc the dependency and use the size as the height, and fetch number of github contributors as width

BoppreH6 days ago

Ask and you shall receive: https://stacktower.io/

CivBase6 days ago

Oh cool. That's a promising start.

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.

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.

seydor6 days ago

without touching the block, after a while it begins collapsing, which makes it an even better representation of infrastructure

Nevermark6 days ago

As entropy increases, the stack rises.

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.

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.

And sometimes, the stack just falls apart because.

In between those extinction events, layers that spawn the most layers, and form opportunistic bridges over lateral layers, dominate and thrive.

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.

This is wonderful.

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.

shadowgovt6 days ago

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.

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.
