This is such a great page, i love it and came across it multiple times while studying the matter.

I still would vote to learn it from Milewski though. Learning this is a journey and the author of ct-illustrated is, i think, still in the middle of it.

Milewski has made that trip multiple times already. The book and his blog are great places.

How generative art works (2022)
>It always surprised me that there aren’t small, local lithium batteries to provide backup power for critical components like the smoke detectors

There is, well, only lithium on the 787. If all power generation is dead, then the most critical flight instruments and gauges get about 20-30 minutes of power from the plane's batteries, things like your backup old fashioned gauges, the engine computers, and maybe some basic flight computer on newer planes. The RAT is intended to keep flight surfaces operational when everything else is utterly fucked, so it usually produces the same kind of energy as whatever the primary flight control system uses, which until recently was hydraulic power. On civilian airliners they generate tens of kilowatts. Airliners do not want to carry around an EV sized battery for the extremely rare occasions when you lose all systems, because that's a waste of gas. The RAT provides the same functionality for lower weight.

When the RAT is deployed, you do not care much whether a smoke detector is powered, you are already vectoring towards an attempted landing.
Tesla is aiming for a camera only method, whereas Waymo is going for a camera+LIDAR approach.
> What kind of nonsense is that, lmao.

I mean, immense corporate codebases is the bread and butter of IntelliJ Idea and where it has a reputation to shine. I don't doubt that you are commenting in good faith, but the exact opposite of your experience is what most people have been saying about it over the years. Have you considered reporting the issue to them?

My experience of vscode LSPs across several languages is that they too use many GBs of RAM over time, just what you would expect from an IDE (and not from a text editor), while delivering pretty poorly feature-wise (unlike idea-based editors, I can't trust vscode to know how to rename variables across languages e.g. from models into templates/SQL, and that's a pretty essential bar to cross in my book).
There is absolutely no way they are remotely close to being revenue positive (unless you're asking strictly if they are charging more than the gas they're burning without counting anything else). They have like 700 very expensive taxis and a burn rate measured in billions of dollars per year.
Big Tech is largely set of interlocking duopolies.

* Ads: Google/Meta

* Cloud: Amazon/MS

* Mobile: Google/Apple

* Desktop: Apple/MSFT

* VR: Apple/Meta

There's also smaller players and sometimes strong third players (eg GCP), but by and large there are no single winners. Waymo and Tesla are looking like a good bet on the self-driving duopoly. I think a lot of people are skeptical on Tesla because "LIDAR", but lidar is largely irrelevant. It is only used in 3D scene reconstruction, it has nothing to do with actual driving which is the hard part.

I don't think it's complexity keeping Arc from being a massive company. Notion is probably the most confusing software to use.

But people still love it, and they have captured the gen z audience (see tiktok).

Any idea on how does Sonnet does this, is the image annotated with bounding boxes on text boxes etc. along with its coordinates before sending to sonnet and it responds with box name back or co-ordinate back or ? is SAM2 used for segmenting everything before sending to sonnet ?
There's a few other metrics people should care about:

"As of June 2024, there have been forty-four verified fatalities involving Autopilot and hundreds of nonfatal incidents."

Have there been any for Waymo? None that I can find.
Techy does not mean technology
Thanks, i was expecting something beyond just the lidar thing.
Can you elaborate more about mapping + remote ? I've never tested neither a tesla autopilot nor a waymo (european here).

edit : also, are there differences in the core algorithms ? Tesla seems to be full AI / ML. Is waymo the same ? ( as the company is older i wonder if they haven't built more things manually)
That's also evolution.
It looks more convincing this way, especially when your audience know nothing about antibodies. HN is just not you target audience. IMHO, it will work well in a pub after a drink or two.
One major difference is that Waymo went all in on lidar while Tesla did not.
This is silly. The conversation is about L4 autonomy. Summon isn't fully driverless by any stretch of imagination. It requires the driver to be within a few feet and hold down a button in the app (essentially a kill switch). Moreover, the liability is still with the driver.
Tesla thinks they can do everything with nothing but cameras. Everyone else is using multiple sensors to give the computer additional info to verify what the vision is sensing. At this point it seems extremely unlikely Tesla will ever produce fsd with vision only. Probably why they added radar back into the model s refresh. It is currently not enabled afaik.

I find it fascinating the crew of Tesla fanboys on this site that run around downvoting anyone who isn’t drinking the koolade, but never have anything factual or constructive to add to the conversation.

There is literally no indication at all that Tesla is right and every other expert in the industry is wrong about vision only never working. We’re a decade in and they still can’t prevent phantom braking that a 2010 ford Taurus didn’t suffer from.
Building a Planet Atmosphere: Fundamental Physics and Chemistry
This an explanation from a layman on the auto side.

Tesla has focused on attempting to solve all cases using vision and generalize it as much as possible. The pro is you would be able to drop FSD capabilities anywhere in the US and it will work. The con is the tail of edge cases take significantly more effort then the first 80%.

Waymo instead of being generalized, works off of a detailed map for each region they drive in. They have a complete expectation of every detail on those roads and so then only need to account for the dynamic unknowns on the road. The pro is that they are getting to hands off driving sooner. The con is that anywhere its deployed needs detailed mapping and for that mapping to be kept up to date.

Time will tell which strategy pays off.
I have no idea of the specifics of Nuvia's license.

But it's totally common for corporations to make value-destroying acquisitions. Some research suggests 60%-90% of mergers actually reduce shareholder value. Look at the HP/Autonomy acquisition, for example - where the "due diligence" managed to overlook a $5 billion black hole in a $10 billion deal. And how often have we seen a big tech co acquire a startup only to shut it down?

Mergers only seem rational because once a mistake is set in stone, the CEO usually has to put a brave face on it and declare it a big success.

I could certainly believe during the acquisition process that the specifics of Nuvia's license were overlooked, or not fully understood by the person who read them.

No. A Tesla with a driver and a Waymo have a lot in common: "When self driving cars don't actually drive themselves"

https://www.nytimes.com/2024/09/11/insider/when-self-driving...

There isn't a big story to this. Does Waymo share details about how and when its vehicles are driven remotely? Since the answer is no, you can only assume that it is pretty often.

Really kudos to Zoox for turning a profile about them into this unveiling of Waymo. I fell for Waymo's sleight of hand. Aspirationally, we really do want self driving cars.

> engagement bait, daily outrages,

I have a pet theory as to why social media causes many people to feel like it's draining them, and why I avoid news on social media like the plague ... I also tend to mute or silence people that share political content (regardless of partisan affiliation).

Social media, unless you are trying to build a business, is ultimately offering the service of entertainment.

Even if you use Twitter or Facebook as your news aggregator, unless you're engaged in some kind of productive and time-scoped research project, you're doing this on your leisure time.

That means that you just got done work, or you're on a break, or you finally got the kids to sleep or finished all of your household chores and you're now in a position where you can "enjoy" a bit of leisure time.

Which means that you approach social media PRE-drained. You're already tired and you're looking for cute cat memes when what should happen ... you get hit with a rage-bait headline, or one of those douche bags that vote differently from you just posted an opinion about a controversial topic that you have very strong feelings about.

We (on HN) all know that the algorithm is trying to promote what gets engagement, and anything that provokes a strong emotional reaction is likely to trigger engagement.

My thesis is that people turn to social media when they are already in an emotional state that is incredibly inappropriate for engaging with "serious" topics on a rational level.

So everyone just gets angrier and angrier at each other and you leave social media feeling even more exhausted than you were before you signed on looking for entertainment to spend your precious leisure time with.

And then you realize that you just wasted that short precious time that you needed to use for relaxation ... and if you don't do anything to rectify it then your stress levels just gradually creep up, your sleep starts to suffer, you might start to compensate with stress eating or consuming more alcohol or cannabis than is healthy and it just spirals.
Tesla chose to recklessly endanger lives, killing at least 50 people by releasing an unsafe beta test. Their goal was to capture market share from Waymo.

This is the thing that drives me nuts: wantonly ignoring regulations designed to protect consumers, and claiming that it was going to save more people than it hurt, in the long run. Tesla's participation in the market has not and will not make self driving arrive earlier than if they had refrained from participating. All it has done is given them an opportunity to compete for market share, and engage in pump and dump scams by misrepresenting their progress to naive investors.
They never were. They get occasional labeling / decision making support from humans.

You're missing the point of DSLs like CEL which is that they can easily be embedded. CEL is quite efficient and supports partial compilation and cost heuristics which makes it very cheap and easy to insert in a hot path that processes arbitrary customer data.
For those looking to easily build on top of this or other OpenAI-compatible LLM APIs -- you can have a look at Langroid[1] (I am the lead dev): you can easily switch to cerebras (or groq, or other LLMs/Providers). E.g. after installing langroid in your virtual env, and setting up CEREBRAS_API_KEY in your env or .env file, you can run a simple chat example[2] like this:

python3 examples/basic/chat.py -m cerebras/llama3.1-70b

Specifying the model and setting up basic chat is simple (and there are numerous other examples in the examples folder in the repo):

import langroid.language_models as lm
import langroid as lr
llm_config = lm.OpenAIGPTConfig(chat_model= "cerebras/llama3.1-70b")
agent = lr.ChatAgent(
lr.ChatAgentConfig(llm=llm_config, system_message="Be helpful but concise"))
)
task = lr.Task(agent)
task.run()

> Waymo is very tight lipped about their operational costs, I would really love to know how close they are to being revenue positive. Recent moves by Waymo suggest they believe they are getting close.

What specific "moves" by them indicate they are close to being profitable? All the industry research I get indicates they are still negative to the tune of $1B+ a year.
Please cite your source for the supposed HN policy. I sometimes answer nonlawyers' questions about how the law works; my answers often attract upvotes. If purists insist on downvoting AI-assisted answers, I can live with that.
What's the exit here? They've raised over $10 billion at VC multiples, valuation around $50 billion. Do they expect this to be a $1 trillion company, even then the return would be a modest 20x.

I feel when that much money is at stake and such a high exit is expected, this could distort incentives. I feel like investors would prefer to set their money on fire for some tiny probability of that 20x+ return rather than look to actually make a modest profitable business
This is a bit of a tangent, but this is how I would actually solve the problem in Ruby:

It's really just a question of the transit provider giving you access to the data. My display shows mostly light rail schedules with a few buses. If your transit provider has real-time data for trains you can display it, if not you can't.

Touched on it to your original question but they require cars to drive through their service regions on a regular basis to keep a very detailed map of the environment. Not just the 2d map of a representation of the entire environment. On the remote part, Waymo will encounter trouble and they have support to take control of the vehicle remotely.

>Private spaces where small groups collect may be social media by its definition

Kind of, depending on the platform, if you squint your eyes at it?

I suppose it doesn't matter what it's actually called. I call it community in general.

Communities in this sense are the middle ground between your direct personal network (which is also the deepest form of relation), and social media as the widest (the shallowest form of relation) form of reach.
If you mean "driven or steered remotely": They were never teleoperated. I'm assuming that would be completely reckless given the nature of radio networks and possibly because of regulations. The car will call a service once it can't make a decision (this is only when the car is fully stopped), and a human will decide to send out a driver or make a decision in the moment.
> some people dying early while everyone else went about their business

So, evolution - just framed correctly.
People get hung up on the vision stack and mapping. Obviously, any self-driving car needs a way to perceive the world around it, and Tesla’s approach is very different from Waymo.

The software that actually does the driving, ie turns the wheel and works the pedals, is very similar between the two companies. Tesla took a big step in Waymo’s direction earlier this year when they replaced their optimization based path planner with a neural network.

When I lived in manhattan I was friends with this hippie spiritual Buddhist woman who was very into reincarnation, she described it as a "glitch in past life memory system".

That would be preferable to AI output on HN. That's the stance that HN and dang have taken, so I'll ask him to chime in in this thread for everyone's benefit.

> IMHO, your peremptory condemnation of posting AI-generated answers — when initiated, and vouched for, by knowledgeable humans — is short-sighted.

It's not my policy. I'm only going off of what I've seen dang say to others, so interpret that accordingly.

> You're of course free to express your opinion by downvoting my comments.

I can't downvote comments that are replies to me, yours or anyone else's. You can't either. No one on HN can. The interface doesn't allow it. I didn't flag your comments either for that matter, because I didn't want to derail our discussion, as you can't reply to a comment that is dead. And that's all I'll say on that matter, because:

> Any path—periodic or not, closed or open—can be represented with an infinite number of epicycles. This is because epicycles can be represented as a complex Fourier series; therefore, with a large number of epicycles, very complex paths can be represented in the complex plane.

We didn't get any new evidence that required modification of epicycles! We got a phenomenon which constrains the epicycle theory by adding more circles! <-- you.

> If anything, it could constrain DM. Why wouldn't you explore this possibility?

You're the only one suggesting that we throw out DM as a model right now... at no point have I even hinted at not exploring it. You are bashing someone who is simply suggesting that this model might not be correct (how fucking dare I...).

But the thing about models... no model is correct, but some models are useful.

Again - I'm not contesting that DM is currently a useful model for explaining some of things we're seeing. I'm suggesting that it might also be worth considering alternatives (how fucking dare I...).

Go back to trying to burn Galileo alive. It's the same energy.
Then, they should have done their homework because any transferability clause would be in Nuvia’s licensing agreement.

Show HN: Bookface for Non-YC Founders
Excited to announce my new project, Rally! It’s a useful community for early-stage startup founders, inspired by Y Combinator’s Bookface.

Site: https://rally.socap.ai/

We think many problems that founders have can be solved 10x better through other founders, but there’s no tool/place to do that well and at scale.

For example, instead of googling how to launch on PH, reading blog posts, etc., you could ask for an intro to a famous hunter who’ll explain all that and hunt your product.

We're building this place + software to make it work really well.

What Rally is:

• A network of highly-vetted founders; many are YC alums
• Bookface-like forum for structured discussion
• Chat for quick qs / asks
• Searchable forum archives
• Searchable and detailed founder profiles

What you can use it for:

1. Getting warm intros for fundraising, sales, hiring, etc.
2. Getting individualized, comprehensive advice on all things startups, from cloud providers to burnout to PMF
3. Solving problems of all kinds, from your app being banned at the app store to getting a $XXk cloud provider bill
4. (Optional) Talking to other early-stage founders once a week during our office hours

We think it’ll work because of highly-vetted members, self-selection by our thesis, and thorough moderation.

Like YC, we’re also looking for ambitious founders working on interesting things that grow very fast. But, in addition to that, we only recruit founders who believe what we believe: that many problems they face daily can in fact be solved through other founders, that there’s no great tools that help with this, and that it’d be cool to have one.

If you’re interested, you should try it out! Rally costs $49/month with a refund if you don’t find it useful.

Apply here: https://ywreftjvygn.typeform.com/to/vpekITsX

Our process consists of an application and a Zoom interview. We’re planning to accept 30 founders in Oct-Nov to get things going, and then open up for more applications.

Join the Rally!
You kind of have it correct, but Tesla is using vision, AI, and huge amounts of data. It’s like the chat-gpt of autonomous driving.

The data is the most important part, to solve real world driving everywhere, you need huge amounts of data for all the edge cases. Tesla has millions of cars on the road gathering this data, vs a couple of thousand for Waymo
