Same reason Homa isn't used: software isn't written for it.

With SCTP there's also a significant performance impact because many drivers for the protocol are far from optimised, because very few applications use it, because of its performance implications, because very few programs use it, etc. etc.

There's also firewall issues: big firewall vendors just don't play nice with anything that's not a variant of HTTP(S). You still need some kind of firewall in a datacenter and it'd be foolish to set up two different ones for internal and external networking. Protocol ossification is real and if you use any external piece of firewall kit, you're sure to run into problems if you try to use "novel" protocols like SCTP. Hell, you'll be lucky to get good IPv6 support.

You can write your own access control if you want but that's often perceived as more expensive than buying a box, especially if the box companies find their way into a meeting with management.

Lastly, there's education. A shocking amount of developers have no idea about how networking works. They probably know there are protocols like UDP and TCP but their role and inner workings are often glazed over in my experience. Practical networking courses seem to treat the network as some kind of black box where bytes and IP addresses go in and response data comes out. If developers do know their basic networking, that information is often out of date; people don't seem to realise how often TCP gets tweaked to behave slightly differently to improve performance. Ask your average dev something about IPv6 and I doubt they'll know much more than "it's IPv4 with more bits" because networking simply doesn't come up that often.

In the end, it comes down to tradeoffs, experience, and decisions. Feel free to write SCTP code for your servers products where you can, the protocol definitely solves many issues people run into in TCP, but you'll probably have to defend your use of something unfamiliar to many developers every step along the way. The same is true for protocols like QUIC (outside the HTTP(S) environment) which tries to solve a whole lot of layer 3 to layer 5 problems in a single protocol that's designed to play nicely with shitty middleware boxes by its basis in UDP.

You might have benefited from MVHR, dMVHR, or an EAHP:

* MVHR extracts air from "warm" rooms like kitchens and bathrooms, runs it through a heat exchanger to warm new supply air, and then pushes the supplied air into other rooms in the house. It stands for Mechanical Ventilation with Heat Recovery. These systems can significantly increase the efficiency and comfort of your house, provided you also air tighten.

* dMVHR is similar, supplying fresh air but reclaiming heat, except the "d" is for distributed. They're like extractor fans but they don't waste the lovely heat.

* EAHP is an Exhaust Air Heat Pump. Usually they sit on top of an invented (eg pressurised) hot water cylinder, and they'll take hot, humid air out of whatever rooms you duct them to, heat you water for a quarter of the cost of an immersion heater, then blow cold air out of your house. This is a great option IMO (I have one) but unlike the first two options it depressurises your house and draws cold air in from outside through drafty bits of your house unless you have a corresponding system to warm incoming air at a similar rate to it being expelled.

tl;dr there are options to recover the heat while expelling the moisture!
Some of us have already left the Meta ecosystem years ago after finally waking up to that.

I watched couple seasons of Santa Barbara.
Hmm I didn’t really read about it.

The proposal here is to replace IP as well as TCP?

Good luck pulling that off.
> Yes!!! I have been saying for years that lower level protocols are a bad joke at this point, but nobody in the industry wants to invest in making things better. There are so many improvements we could be making, but corporations don't see any "immediate shareholder value", so they sit around happy as pigs in shit with the status quo.

If this was true then how do you explain that the likes of AWS, the same company who ended up investing in developing their own processor line, doesn't seem to agree that none of the pet peeves you mentioned are worth fixing?
Oh I'm not saying that they should be released.

I'm asking about what's happening inside those prisons. And what happens to the prisoner after he's released from said environment. Is there a net benefit to society with the current status quo?

I guess in short a better way to put it is this: Is the prisoner reformed and able to reintegrate with society?

The alternative is that right now, all that social maneuvering is focused on the IC to the manager. It's much more difficult for the IC to social maneuver all the different IC's into a facade of competence, than to be competent or focus all the bs on a single manager.
There's a kind of hierarchy of search depending on the niche you're looking to move into (e.g., large corporate, FAANG, FAANG-lite or scrappy startup).

I start out with the type of company I want, usually dictated by lessons learned working with previous bad employers. Tech journals, Glassdoor, Levels.fyi, Slashdot, Y Combinator etc. will get you a potential list depending on the scale.

Then it's polling my developer network on LinkedIn to find 2nd or 3rd "hops" away that get me access to that area, and asking someone to setup an introduction. Once introduced, I start trying to figure out if the company is all just a marketing smokescreen, or whether they do indeed do quality engineering.

Then I try and actively connect with recruiters via Indeed or LinkedIn and search their jobs pages - you'd be surprised the number of roles that aren't quite ready to be advertized just yet, but would be top-of-mind for technical recruiters.

Lastly - when I start a proper job search, I go wide! Get about 20 companies like that in the funnel, which might yield 2 or 3 quality interviews and maybe 1 offer. If there's anything you don't like, pull in another 20 companies and go again. It's completely a numbers game.
The real abuse of course is $5 a minute toll line. The ability to rack up that kind of charge should be opt-in, there’s basically no legitimate use case.
Peer reviewed work has a much higher bar for people to say stuff. If you want to know what academics think, as opposed to what they are motivated to write and get past a reviewer, you need something like twitter.
Plus, some academics are interesting people and say stuff of interest away from the specialism.
I can't explain why, but I have never really gotten along with Thermos mugs. There's just something... off about the taste, or the way the mug feels on my lips, or something, I'm not sure exactly what.

The Ember is ceramic, and apart from being a bit heavier, feels exactly like a normal mug.

Absolutely agree when I first got it as a gift it seemed like a solution looking for a problem, but actually using it has completely changed my perception of it.
The Wii U was unfortunately not a very successful console, but I feel that it had plenty of power to make fantastic looking games and great experiences. It came out in a weird time for technology and Nintendo always uses slightly older hardware.

As a homebrew device it is amazing. There are still exploits being found with a new, safe, simple method out now thanks to some crazy dedicated modders.

There’s a whole homebrew sdk. The Wii U can also run Wii and GameCube games by reconfiguring the hardware (or some other sort of firmware voodoo). That’s three generations of video game libraries that can be explored on one console!

Always felt like it deserved more popularity, but it couldn’t compete with the ps3/4 and Xbox 360/one.

> but it doesn't seem that UDP drops actually occur on a routine basis anywhere.

I have seen code that didn't even handle out of order delivery work well for over a decade in local networks. Even when that broke down it turned out that IP package fragmentation just triggers a slow path in smart switches, so if your packages fit into the networks MTU (with some bytes to spare for VLAN tagging) you still might be able to avoid the problem.
> because once either an endpoint is compromised, or a tap is within range, you're still giving your adversaries everything they could desire

This is hogwash because it is the wrong threat model. The encryption in this kind of communication is nearly pointless. If you're trying to organize a protest where you have to be messaging 100+ people then there's no way you can vet everyone. There's going to be a mole. In fact, we saw this with some of the militias at Jan 6th. Despite using Signal their texts got turned over. You just have to turn one person to compromise the system.

Would I rather have the communications encrypted? Hell yeah. I'm that annoying friend that makes everyone use Signal. But it is absurd to think that wire tapped mass communication is worse than no mass communication. Revolutions and protests are won my shear mass. They often show their faces and are demonstrating in a public space (where there are often plenty of cameras: CCT, Police, and the protestors themselves!), so there's no concern about privacy already. Many get arrested, you can't arrest a large group. Arresting everyone would be nearly impossible.

Furthermore, people still use covert speech. People are doing it in Iran right now. People are doing it on highly censored platforms like WeChat. Hell, there's covert speech on Twitter. There's definitely an advantage to using phones rather than going down to the public square and organizing that way. If you think everything is/was organized in back rooms and in complete secrecy, you're gravely misinformed at how these things work in reality.

You have the wrong threat model.
I am sorry for your experience, but in a newborn this will also probably be of limited use.

Note that the signal to noise ratio will be very low in a newborn, smaller humans means smaller vessels and less blood pressure. If it was my child I would much rather have an ultrasound guided cannulation then to trust this device.

The reality is that although it looks very flashy it will have limited use other than maybe training very junior nurses/doctors.
It’s down to JJ Abrams style of writing. He’s frequently talked about his love for a “mystery box” where he believes a good mystery is better than fact. The problem with his writing is, unlike most other writers who use mystery boxes, Abrams doesn’t even know himself what is inside that box. And you see this across all of his work.

Frankly, I find him to be the most overrated writer and director in Hollywood because of this. I find everything he does to be borderline unwatchable. Though with his recent criticisms for Star Wars and Star Trek, it does feel like his audiences are starting to lose their love for him too.

Obviously in a more involved (enterprise) setup a firewall will make sense for several reasons, but on a small server you rent for yourself to run an httpd and let's say an ircd plus ssh, what exactly do you think a firewall does for you?

Reading through the responses here there seem to be 2 kinds of ways to look at things:

1. Manager needs to be the most knowledgeable, and steer the team with the correct decisions.

2. Manager cannot be close to the code due to other responsibilities, and so needs to trust their team for the technical things.

Personally I have the following opinion: a lot of companies can follow 1, since once you know how to flip burgers, you know. The smarter people rise and can have more influence. However in knowledge work, the people most knowledgeable are close to the code. When you move up, you will know less and less (code evolves quickly).

I'm 20 years in the software development business, and I only work for managers that understand they don't know, and trust & empower their team to take the right technical decisions. It really surprises me that some developers here think differently.
It is sort of a common practice to get rid of "problem" customers too.
> It is simply (physically) not possible for the existing cameras to see the area directly in front of the car.

Think about how a human driver does it, given his/her even worse vantage point. They model what's in front/behind the car from afar and remember what's where as they approach it. There are other signals as well, such as continuation of a kerb, etc.

I think people keep forgetting that Teslas run hundreds of ML prediction tasks all the time. Watch recent AI day and their talks about "occupancy network" to get a sense of the car's ability to:

1. Construct 3D model of its surrounding in real time;
2. Remember occluded sections based on what's it's seen previously.
As an example https://aaronparecki.com/ does it, but when it comes to documentation entry page https://activitypub.rocks/ and otherwise https://www.w3.org/TR/activitypub/
Single-variable letters and suggestive notation make it easier to recognise patterns, and give a good level of abstraction at which thinking about the problem rather than muddling through notation can happen. For example one can rather easily check

a(b + c) + (b - d - a)(b + c) = (b - d)(b + c)

But it will be hard to simplify

add(mul(amins, add(boo, cold)), mul(…

You are not expected to understand what the notation means without further context, in the same way a programmer is not meant to see a function call to main(foo) and understand what will happen.
Are there any open source or CLI vectorizers as good as Vector Magic?
I've been looking at PNG-to-SVG tools and Vector Magic's quality is amazing. The only problem is it's a web / Windows / Mac-only app and I'm looking for something I can run programatically on a large collection of images. Having trouble finding one that works - any suggestions?
I doubt it will be that simple. Audio fingerprinting a la Shazam works by identifying key elements in some transformation of the sound, and setting some threshold for the number of matches. I suppose the output of this compression method offers a good way for identifying a song by a bit of sound, but the identification algorithm will be much more complex.

I'd like to see what happens when you modify the stream. If the representation is really that compact, making small changes should change the output considerably. Treat it like a synthesizer, really. That should tell us something about its usefulness in identifying audio.

Looks like you can select the part and there's a toggle to show a voltage tag which hovers over the part during the simulation. Very rudimentary as yet.
You can think of `i` as a rotation by 90 degrees counterclockwise.
You do it twice and the real number line gets reflected (as if multiplied by -1).
It is what multiplying by i actually does to the complex plane.
Strange how this is so far down the list but a more recent "nobody in the industry wants to invest in making things better" rant is higher upvoted.

Clearly, AWS knows a thing or two about the datacenter industry, wanted to invest in making things better, and DID invest in making things better - and even published a paper on it.
From an engineering perspective I would ask:
Can your sensor package understand the environment to the required (low) failure rate?

Radar/Lidar/Ultrasonic is going to give you information that your camera systems will not give you.
It does not matter if the delta of information is little. If this little is required because you can't obtain it otherwise, you still need it.

If you just rely on the fleet, you rely on the things you have seen.
What about the objects that you have not yet seen?
Which games really used the secondary screen in an interesting way? The main ones I can think of are:

Splatoon— second player without split screen.

New SMB U— gamepad player can spawn blocks to help you reach secrets.

Wind Waker— map and inventory.

But an awful lot of titles just mirrored the TV or had a button to enable off-TV play.
> I find very strange the claim that a moving doppler (pulsed doppler?) radar 'generally doesn't help to detect stationary objects'. I mean if the car is moving, it generates a doppler shift on all objects moving at a different speed, right?

I’m in the same boat as to not understanding why, but from what I have read the problem indeed isn’t that it doesn’t detect them, it’s that there are too many of them, and nobody has figured out how to filter out the 99+% of signals you have to ignore from the ones that may pose a risk, if it’s doable at all.

I think that at last part of the reason is that spatial resolution of radar isn’t great, making it hard to discriminate between stationary objects in your path and those close to it (parked cars, traffic signs, etc). Also, some small objects in your path that should be ignored such as soda cans with just the ‘right’ orientation can have large radar reflections.
Why don’t you actually build gasp a prototype before asking for money
Beautiful explanation. After reading this I wonder if anyone knows about homomorphic encryption and ZKP uses for role/policy management? Or something similar?

They main uses I know for ZKPs are in open distributed scenarios but I wonder if it could be used to simplify other spaces where public/private keys are involved.

For example, instead of having a user creating roles and policies and storing all of this info in a traditional DB we could have a token system based on homomorphic keys that we can verify... Where we could aggregate tokens, generate tokens with specific policies on-demand without storing it in a DB...
> all the politics was getting annoying

Dumb question but why would this be any different on Mastodon?
> What you're talking about though isn't just coming up with new ideas or even new products. It's replacing hundreds of billions in infrastructure wholesale.

I'd put it differently: it's paying up hundreds of billions in infrastructure to have some sort of gain.

And which gain is that exactly?

I see a lot of "the world is dumb but I am smart" comments in this thread but I saw no one presenting any clear advantage or performance improvement claim about hypothetical replacements. I see a lot of "we need to rewrite things" comments but not a single case being made with a clear tradeoff being presented. Every single criticism of TCP/IP in this thread sounds like change for the sake of change, and changes that aren't even presented with tangible improvements in mind or a clear performance gain.

Wouldn't that explain why TCP is so prevalent, and no one in their right mind thinks of replacing it?

There is nothing wrong with committing generated code in Ent and Go. I don't know about Java but in Golang it does not create any platform-specific code in general, so committing code in the VCS would ensure reproducibility.

It is still OK to commit without generated code and things won't break as long as you pinned the package versions correctly. But some people don't like to put extra burden in the build phase. So it is totally organization's decision whether to commit generated code or not.

Anyone read it all and can tldr any interesting insights?
My best guess is that all they meant by "CD quality" was that it was targeting full band stereo replication, rather than narrow band as is typically used for speech. Not that it could achieve transparent compression at any particular bitrate.

The tiny music clip in the sample, encoded at 6 kbps, is obviously not any kind of evidence for "CD quality" one way or the other. (The clip itself, if you download it from the page, is re-encoded with 64 kbps AAC.) No way to know how it would stack up against 96 kbps Opus on a stack of CDs with blind testing, I don't think.
