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 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.
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.
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.
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.
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.
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?
> 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.
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.
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.
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.
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.
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...
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.
Truly baffling, you're voluntarily disabling a critical piece of how websites expect to function and then act shocked when web sites don't cater to the >>0.0001% of users who decline to allow their site to work.
Why are you assuming I disabled javascript? The bullshit here is you thinking you know better than anyone else. You should get flagged for such ludicrous claims, not me.
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.
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...
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.
I noticed that when I drag an object, the force appears to originate from the object's center of mass rather than from my cursor. So it feels a little weird.
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.
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.
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?
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's 2,347. There's also 927. And 538, and who can forget 386. 936 is also a classic. 1205 is a favorite, although AI changes the scales these days. As does 303. 1838 is another good one for when CC is "thinking". 1425.
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.
Im sure whatever’s happening isn’t intended but I did experience jankyness when trying to use the back button on Safari on iOS. It wouldn’t let me go back.
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.
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.
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.
You’re 100% right to call that out. The current GitHub OAuth scope is too broad
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.
Damn dude. That’s awesome! I saw the permissions it wanted out of every org I’m a part of (including some big open source orgs) — I’d probably find myself booted out of those orgs if I accepted that. They def get a notification on every authentication like that and take potential impersonation seriously.
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!
> If only it wouldn't collapse by itself after clicking anywhere (clicking seems to activate physics) this would be 10/10
I think that's the other metaphor here.
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.
Not sure. It's not it being unstable, it's small bricks moving bigger stuff to the side and maybe even upward. If I missed the joke I just don't find it funny.
