> How will waymo help with something like the super bowl? It's going to be overcapacity too.

Ability to scale the amount of Waymo cars to an area is immensely easier than scaling the amount of Uber/Lyft drivers available and willing to go to said area.
Mostly this. Sandboxing on basically every single modern browser is better than sandboxing on mobile devices. Nearly any app that's delivered as a PWA is going to have better privacy guarantees than an equivalent native app.

The difficulty of course being that PWA limitations make many offline-only or account-free apps nearly impossible to build as PWAs.
I visited Barcelona 15 years ago, they cleaned the streets every morning.
On Unix targets it installs a signal handler for SIGSEGV and checks if the faulting address falls within the range of the stack guards. See https://github.com/rust-lang/rust/blob/411f34b/library/std/s...

The stack guards would normally be setup by the system runtime (e.g. kernel in the case of the main thread stack, libc for thread stacks), not Rust's runtime. Likewise, stack probes that ensure stack operations don't skip guard pages are usually (always?) emitted by the compiler backend (e.g. GCC, LLVM), not Rust's instrumentation, per se.

In this sense Rust isn't doing anything different than any other typical C or C++ binary, except that automagically hijacking SIGSEGV (or any other signal) from non-application code as Rust does is normally frowned upon, especially when it's merely for aesthetics--i.e. printing a pretty message in-process before dying. Also, attempting to introspect current thread metadata from a signal handler gives me pause. I'm not familiar enough with Rust to track down the underlying implementation code. I presume it's using some POSIX threads interfaces, but POSIX threads interfaces aren't async-signal safe, and though SIGSEGV would normally be sent synchronously (sometimes permitting greater assumptions about the state of the thread), that doesn't mean the Rust runtime isn't technically relying on undefined behavior.

EDIT: To get the guard page range it's using pthread_self, pthread_getattr_np, pthread_attr_getstack, and friends, of which only pthread_self is async-signal safe. See https://github.com/rust-lang/rust/blob/411f34b/library/std/s...
I have no concrete evidence to believe the reliance isn't safe in practice on the targeted platforms (OTOH, I could imagine the opposite), but it's a little ironic that it's depending on undefined behavior.

Hi, I'm Tarin, a freelance software engineer, I am working with Rust, Tauri, and mostly developing high performance data mining applications. I also work with Python programs, and have experience of 14 years. Right now I'm also working with htmx + tailwindcss + Axum for developing web applications. I have also worked with spring boot, reactjs.

Arguably a lot of it is "done". They sell subscriptions to third parties...
All of my scary moments in a car were on long road trips where public transit doesn't really apply, and with pedestrians walking out in front of my car on green lights (probably fent related also).
It would be nice to have an UberSSR option for sure, for the people that just want a ride.

Yikes... In the same doc:

>"For example, the separation between kernel mode and user mode is a classic and straightforward security boundary."

>"Non-boundaries: [...] Administrator to Kernel [...] Administrative processes and users are considered part of the Trusted Computing Base (TCB) for Windows and are therefore not strong isolated from the kernel boundary."

The reasoning makes sense, but that's quite a mixed message for an unintuitive nuance.
I read the paper.

Per token error is a fairly useless metric. It's not predictive and it tells you absolutely nothing.

They say it's a superior metric but clearly the wider research community disagrees since no one has cared to adopt per token error as a metric in subsequent papers.

>and the fact that "emergent abilities" do not occur when using this metric is a strong argument that those abilities don't really exist.

If your conclusion is that those abilities don't exist then you clearly didn't read the paper very well.

They never argue those abilities don't exist, they simply argue whether we should call them "emergent" or not.

>However thermal energy does not more precisely or specifically measure a phase transition. They are only indirectly linked - nobody would say that thermal energy is a better measure of state-of-matter than solid/liquid/gas. Your argument makes absolutely zero sense. Frankly it seems intentionally ignorant.

Phase Changes are literally driven by changes in thermal energy.

Water boils when it absorbs enough thermal energy to break intermolecular forces keeping its liquid state together.

solid/liquid/gas is descriptive. It's not a measure of anything.

Anyway, the point is simple. Despite thermal energy driving state change after a certain threshold, that "point" doesn't look like anything special.

Smooth quantitative change sometimes results in sudden qualitative changes.
It's certainly going up in price as people get off the waitlist and the number of vehicles allowed in service stays fixed. I'm optimistic, though. I would travel a lot more if the price was cheaper, I assume Waymo has enough data to realize that, and they will act in a way that creates a larger market, rather than squeezing the existing market, once they have the legal ability to do so.
I worry about that too, because of that I'm very hesitant to give out my CV.

I also wonder what advantage they get by having my CV when my work history is public on my linkedin. What do CV farmers gain from having a pdf of my CV? Couldn't they just copy-paste the information from my linkedin if they really wanted to?
The trouble with oral agreements then become determining what is in the oral agreement, after the fact. Whether one party remembers it differently to the other, either due to poor memory or deliberately.

I don't think the problem is with having a for-profit wing. The problem is that only the for-profit wing got to use the technology developed by the non-profit, when the non-profit was explicitly tasked with releasing the technology to the public, allowing competition.
And what games would that support?

A very small minority of games support Vulkan.

Try giving https://pjvogt.substack.com/p/why-are-drug-dealers-putting-f... a listen. There are many reasons, some more plausible than others, but most surprising to me is that there’s a heavy amount of demand for it.
> As long as there is competition the prices will be low (eventually).

We don’t have to wait here. Is BigCo lowering prices on YouTube subs? Are they lowering ad spend for people?

You could claim that they’re a monopoly in those cases, but then that would undercut your expectations above.
>It's well known that speed differences on the road are a major cause

the speed differences you are referring to are road design situations such as highways dumping traffic into downtown traffic. delta V isn't recognized as a severe problem by IIHS nor DOT. speeding very much is.

source: https://highways.dot.gov/media/13876

--What is the effect of speed differences?
In addition to absolute speeds, the speed differences between vehicles also have an effect on the crash rate. This effect is studied in two ways. The first type of studies are those that compare the crash rates between roads that have a large speed variance (large differences in vehicle speeds during a 24 hour period) and roads that have a small speed variance. These studies mostly conclude that roads with a large speed variance are less safe (Aarts & Van Schagen, 2006). The second type of studies are those that concentrate on the speed differences between the individual vehicles that were involved in a crash and all the other vehicles. The first studies of this type were conducted in the United States in the 1950s and 1960s, e.g. Solomon (1964). These studies always
found a U-curve: the slower or faster a car drives compared with most of the vehicles on that road, the more the risk of being involved in a crash increased. However, more recent studies, especially those carried out in Australia (e.g. Kloeden et al., 1997; 2001; 2002) that used more modern measuring instruments and used a more accurate research design, reached a different conclusion. They still indicate that vehicles that drive faster than average on that road have a higher crash rate; vehicles
that drive slower, however, were found not to have an increased risk (Figure 3)

They don't really need to decrease in price so much as not increase in price. Human labor keeps getting more expensive while the tech is probably getting cheaper, if they are just competing with Uber/Lyft, they can wait this out. On the other hand, they could definitely grow the market for taxi-like services like Uber did when it initially came out, but without unsustainable VC subsidies.
Yup. I felt like some kind of massive failure or something for the first 4 years because I didn’t even know what was wrong and I basically didn’t know any other parents had struggles this bad. Now I still feel terrible because everything sucks, but I know it’s not all my fault or normal.

I’d offer that Musk hasnt shown any consistent principle motivating his behavior other than gathering power, in the face of stated motivations.

So while he may genuinely believe what he is saying, the inherent philosophical conflicts in his consistent narcissistic actions, have poisoned any other possible position to such an extent that he has lost all moral credibility

Maybe. Or you've just been "lucky" with the kinds of experiences you've had on Uber.

I've had some really annoying drivers, shitty drivers. People have reported assaults and some have ended up worse.

If this were a daily thing for people (which it could be in the future), I wouldn't want a 1on1 experience every day (twice a day) with a new driver each time, each with their own personalities, driving abilities, and needs at the moment. Forget that.

They ask for temperature and conversation preferences when you order a black car, which I find somewhat funny.

I love Go's lightweight, somewhat implicit style of doing enums.

You just declare an int type, and then a list of constants of that type.

People are complaining about 'iota' here, but I think it's slick and great. It combines so nicely with eliding types and values from subsequent const declarations:

type MyEnum int

const (
Value1 MyEnum = iota
Value2
Value3
...
)

Nice and simple. Most of the syntax is just the enum value identifiers. And it works well for bit flags too:

type MyFlags int

const (
Flag1 MyFlags = 1 << iota
Flag2
Flag3
...
)

Most of the above syntax isn't specific to enums (so you're already getting a lot of other things from it). The only enum-specific syntax is iota and the eliding type/value rule.

People seem to want their languages to have all sorts of guardrails, but I find many of these cumbersome. Go gives me the one enum guardrail I care about: The enums are different types, so I can't use a MyEnum as a MyFlag, or vice versa.

I've worked on giant Go codebases, with Go-style enums all over the place, and the lack of compiler-enforced exhaustive enum switches just hasn't been a problem. And it's nice to be able to use non-exhaustive switches, when you want them. Go is simple and flexible here.

The article criticizes Go incorrectly with statements such as these:

> This also means any function that uses these or a struct that contains these can also just take an int value.

> Anywhere that accepts an Operation Enum type will just as happily accept an int.

This is just not true. Here's an example you can run: https://go.dev/play/p/8VGufuxgK6b

The above example tries to assign an int variable to a MyEnum variable, and gives the following error: "cannot use myInt (variable of type int) as MyEnum value in variable declaration"

This error directly contradicts what is claimed in the article. Perhaps they mean that MyEnum will accept an integer literal, in which case I would argue that a guardrail here is silly, because again the problem just doesn't really come up in practice. Regardless, the author is not being very precise or clear in their thinking.
I've worked at a battery-analytics company which given your background you might have heard of, this involved hosting the Bay Area battery research community on a monthly basis. I'm not dismissing lithium sulfur as a viable technology. I'm saying that trying to calculate the environmental impact of a technology like that before it has sizable production and several rounds of process improvement is napkin-scribbling. Useful in some ways, but it's premature to draw conclusions from it. That's all.
I also see 2x prices for Waymo.
Clarity is always welcome and appreciated in such comments. Others on the thread did specifically mean cheaper, though.

Much as it may pain you, “could care less” is an established idiom in American English that’s been in use for 70 years, and Webster’s dictionary has a whole page about it: https://www.merriam-webster.com/grammar/could-couldnt-care-l..., in which they say:

> people who go through life expecting informal variant idioms in English to behave logically are setting themselves up for a lifetime of hurt.
I have no idea what you're trying to say or if you're being sarcastic. There are multiple battery chemistries including lithium iron phosphate (7x cycle lifetime), lithium titanate (50x cycle life or more) and sodium ion (potentially cheaper) that are all on the market to buy right now, not to mention lithium polymer batteries and all the refinements and variations out there.
Li Fe Po4 seems to be more the work horse for the masses.
Think about the way each alternative branch of a Rust "enum" can model arbitrarily nested data. That's completely different from the things in Go and Python that are called "enums".
We all know that Musk's intentions for this are not noble (who would be so naive to think otherwise anyway?) so I'll leave that aside for now but he has a good point by bringing on this lawsuit.

What I love is the fact that people here are trying to justify Sam's action by amusing mental gymnastics such as "AI Safety! Think of Humanity!".. seriously guys? At least we should be honest and call a spade a spade, "open" in "Open AI" is nothing more than Sam's attempt at scamming people with marketing gimmick and dodging taxes. The truth is that Altman knows other AI models are catching up quickly and he is trying seal the deal with regulatory capture as soon as possible.

OpenAI has already lost any credibility they had after the recent implosion with half the team threatening to leave as soon as they realized that their bank accounts might shrink by a few cents if Altman is not sitting at the helm.
The best part is that Sam delivered by making them all supremely rich [0]

This company is a joke and it's all about the money.

When i was in florida at Orlando, my wife and i experienced several of the worst Uber/Lyft drivers i can imagine. We're talking regularly breaking the law while driving, drivers. My wife also regularly encounters drivers she is uncomfortable around.

In general i'd vastly prefer a non-human experience.

I really don't see how a human-centered driving company survives with something that is near fully automated and new "drivers" can just be ordered up from Stellantis or whomever, provisioned, and sent on the road. The scaling laws just don't match up.

I say "near fully automated" because there's loads of operations involved, including human remote fleet management for when cars get stuck. But even that doesn't scale linearly with the amount of automated vehicles on the road, whereas Uber will always be at least 1:1 human:car.

Almost everything where people ask for "more funding", that service is junk and adding money just means you go from getting junk for cheap to getting junk for expensive. I've seen zero cases of it going from junk to even mediocre. I've seen numerous examples of junk going from cheap junk to expensive junk, especially in US public services.

The "more funding" is always allocated towards existing rent-seekers.

And my opinion with getting junk is that if I'm getting it, I want to be paying as little for it as possible.

As a quick test for what you feel, try this. You read a headline that says "This city school received the most government funding of any school in the US". Do you think that school is "great" / "mediocre" / "crap"? My personal immediate inclination is that the school is probably shit.

I suspect that part of the problem is that they got VC money to do the rewrite in rust, and it took very long and the results aren't as amazing as expected.

But that's just my own conspiracy. I have no idea. Perhaps things changed since I last ran the benchmarks.

Benchmarking isn't easy. I know that my software using my library mostly loads Unions, so that's a focus in my benchmarks. However I have absolutely no idea of what the other users are doing with it, and my benchmarks might not be relevant to them.

In the end I wrote them for myself mostly, to check for possible regressions in performances.

PS. I know you asking about just RAW SQL, but I highly suggest you get into understanding how particular DBMS works in depth, what plans it builds, what concurrency mechanisms it uses. Writing raw SQL will get you only so far, making those queries actually production ready is completely different ballgame and for that, you don't need to be super proficient in SQL.
So, will these be geofenced to a small area, or turned loose on the whole Southland? If it’s the latter, I’m genuinely impressed: LA’s roads and freeways have a florid variety of edge cases unlike anywhere else.

In more observant Christian countries, the weekend was taken over by religion. In Italian/French/Spanish, Sunday is domenica/domingo/dimanche, from Latin "domine", "of the Lord"; and sabato/sabado/samedi is from "shabbat".

Btw, I don't know why you skipped "moon day", which is a direct translation of the Latin lunae dies (hence lunedì/lunes/lundì). That survived even better than the others.

> Plus the social damage, lots of those plantations are on indigenous lands stolen by various machinations in the past.

How is this “social damage” the fault of the forestry company and not the folks who took the land 200 years ago?

All land is stolen, as I’m sure the indigenous tribe in Chile who lived there took it from someone else who was already there. I’m not asking the modern ancestors of the Normans to give me back my ancestor’s Anglo Saxon lands in Northumberland. Nor am I blaming them for it 1,000 years later.
Sodium ion is the 200 mile city car for 2+ billion people. Should be half the cost of an ice drivetrain and no limits on materials. Sodium Ion should scale up to $40/kwhr, and cell-to-pack shouldn't be much worse. $100/kwhr pack level is supposed to be price parity with ICE.

And if they can, sodium sulfur will do everything but aviation.

The cook thing with batteries is you can seamlessly mix different cells in the same pack to handle daily driving (reuse a section of the pack they is particularly durable to cycles like LFP) and others for longer range.
