I got a 2026 model Y recently and tried out FSD. It made enough errors in the first few trips that I am surprised it's being touted as a "robotaxi".

For example: travelling West on 15th street in SF, at Guerrero the leftmost lane turns into left turn only and the Tesla happily continued straight through.

That jolted me out of complacence and the next time it was in the wrong lane, I quickly took over and corrected it. It's happened a few times and I don't use FSD that much.

Thanks for trying it out. It's a regular inverse square law, no tricks. The numbers (masses, distance) determine the final acceleration but not the actual trend of the curve.

I've become too familiar with it over testing to notice unintuitive behaviour, but I think I understand what feels off: in real world units, the gradual region you describe is very wide, and feels linear. This would make for very boring gameplay (imagine spending minutes to reach the planet). You need to keep the playable area [radiusForce0, radiusForceMax] small. So you will either map that small [r0, rmax] into real world [F0, Fmax], which means the force will be almost constant across, or "compress" the [F0, Fmax] curve so that you can fit both [zero outer space gravity, strong surface gravity] into that [r0, rmax].

That's what happens here, I probably tweaked the values for the second case. It's kind of an accelerated version of reality and the margins feel very tight, and you have to "buy into" that reality.

For example, Master difficulty in Mission 1 may seem impossible, but if you try to be gentle and find a balanced orbit, you can complete it with miniscule fluctuations in distance and minimal input.

Just rambling though, I never really actually designed or balanced the game.

> Unlike competitors, such as Waymo, Tesla’s Robotaxi still uses a “safety monitor” who sits in the front seat with a finger on a kill switch ready to stop the vehicle. Despite this added level of safety, Tesla is evidently still experiencing crashes.

> CEO Elon Musk has claimed that Tesla would remove the safety monitor by the end of the year and deliver on its “full self-driving” promises to customers, but he has never shared any data proving that Tesla’s automated driving system is reliable enough to achieve that.

LLMs are still executed by code written by humans. In this case, the model ultimately give you a probability distribution over each (~200k) tokens in the vocabulary. It's then up to you to decide how you want to sample the next token, you could for example just always sample the most likely, or to make the output more creative, you can sample randomly from the top-k tokens. This top-k sampling, to make it efficient, is written in XLA and compiled to run directly as a kernel, there was a bug in that kernel, which presumably led to tokens outside of the top-k window be select from times to times.

Two things I really wish literally any company would ever do with their systems when you have a permissions-based token:

1. Show me all the permissions that that token has been granted but has never used

2. Show me all the permissions that that token has tried to use but does not have

I would gladly accept the ability to turn on an audit mode for a given token, service account, etc., run the thing I'm trying to run, and then go look at the report to see what permissions I can remove - or, even better, have a giant "Create role from this profile" that lets me create a custom set of permissions based on all of the permissions I've used.

Google Cloud does have a thing where it shows you all the service accounts you have with "overly broad permissions", but it seems to be just "here are all the SAs with 'owner' access" so far. It didn't catch the service account we had that just needed to publish one file to one bucket but had been made a Storage Administrator with full read/write/update/delete access to every form of storage in Google Cloud.

<On average, african americans are taller than white men and have a higher muscular density.>

Are you comparing direct descendants of Yoruba versus descendants of Celts in America ? or mixed descendants of Bantu and Cherokee versus mixed descendants of Anglo-Saxons and Slavs ? In your study would Barack Obama be a person of color or a person of pallor ?

Or is this data you have gathered observing people at Costco. Just checking on your scientific methodology.

You are looking on it from a wrong perspective. You have access to communications of politicians, military and government apparatus. You can effectively control these figures through extortion (I know about your mistress) or blackmail (I picked up your kids from school today next time I may keep them for a while)

Politicians who are pushing these laws are having a feeling that bad things can't happen to them. However they are usually prime targets for bad things happening to them, because they are the ones wielding the power - if you can influence the politician, you can control his power.

> I wonder if the toxicity of the American culture wars can be contained this way.

Huh? Are you not aware of US social media companies?

Everything that's happening on TikTok is also happening on X, Facebook, Friendster, or whatever the kids are using these days. The only difference is that the TikTok algorithm promotes Chinese propaganda and ideology, and enriches the Chinese government and ByteDance. The US can't have that, hence this deal.

This won't affect the American downward spiral a single iota. That would require strong regulation of social media companies and adtech in general, and there would be a nationwide revolt if that were even proposed. This is far from being considered anyway, now that Big Tech is deeply entrenched in the government.

I don't know about you but my feed is filled with people claiming that they are surely quantizating the model, Anthropic is purposefully degrading things to save money, etc etc. 70% of users were not impacted. 30% had at least one message degraded. One message is basically nothing.

I would have appreciated if they had released the full distribution of impact though.

I have a new browser security method. Inside this link you'll have access to a virtual browser environment. In this environment you will have the ability to control and access a plain text private bitcoin key worth 20$. There is only a single key, first one to take it ends the challenge for all. -> Demo Signup: https://app.redactsure.com -> Bitcoin Checker: https://redactsure.com/bitcoinchallenge

Note: - No mobile, keyboard required - Requires you to verify an email - Any bug is eligible for a prize if it's something I haven't seen before, just tell me.

Some people were asking about implementation I'll provide a few details. - A server hosted browser - I manipulate what you are seeing on the webpage in real time - While I don't change the underlying webpage I do manipulate your actions to the webpage - A transformer model runs in real time along side you (tries to find all sensitive words you see)

Overall the system's goals are to allow you to perform work without ever seeing the data. It's in a early prototype stage and I expect a large numbers of edge cases just from the nature of the problem. The bitcoin is a proxy to the real goal which is protecting real PII in remote work settings.

It would be nice if you tell me the bug. I would like to post how you broke it.

> Who would benefit the most if Chinese models were banned from the U.S tech ecosystem? I know the public and startup ecosystem would suffer greatly.

Ideally, gpt-oss or other FLOSS models that aren't Chinese.

Ideally. Probably won't turn out that way but I don't think we have to really worry about it coming to that.

According to the article, at first the accidents were "hidden" from the reporting system just because Tesla systems were not autonomous enough to qualify under the law.

But now that Tesla is trying to be more autonomous robotaxi service, they're required to report more details about their accidents.

According to the article, Tesla's competitors (like Waymo) are very forthcoming about the incidents. They are probably following the long tradition in engineering of learning from your mistakes by investigating them thoroughly and doing root-cause analysis.

Tesla cannot do this, because if they do a thorough root-cause analysis of why their system fails more than others, they will inevitably arrive at the conclusion it's due to the sensor stack being camera-only. And Tesla cannot admit that because Musk can't admit he was wrong.

So instead they're going down the path of being cagey about the details of their accidents. I don't know how long these reports take to generate but there are 2.5 months worth of reports that have not yet been released.

Meanwhile, Musk has committed to ditching the safety monitors by the end of the year, and he's not going to be able to do that if Tesla's robotaxi service is unreliable. But he's also not willing to do what it takes to make the service more reliable, which is add LiDAR to the system. So... it will be interesting to see what happens at the end of the year.

LLMs produce a probability distribution for what the next token might be. How you pick the actual word that is printed next from that probability distribution is by using a sampling approach[1]. If your sampling approach is "select the next word randomly from among the top 4 possibilities" and you flip a > sign, you could end up with the behavior described in the OP.

Note that none of the CPUs in the article have that Zen architecture.

One of the most interesting and poorly exploited features of these new Intel chips is that four cores share an L2 cache, so cooperation among 4 threads can have excellent efficiency.

They also have user-mode address monitoring, which should be awesome for certain tricks, but unfortunately like so many other ISA extentions, it doesn't work. https://www.intel.com/content/www/us/en/developer/articles/t...

Sure, but you also have to recognize the motte and bailey form of argument here. If we’re limiting the claim to being true if DeepSeek returns refusals on politically sensitive topics, we already knew that. It was relevant eight months ago, now it’s not interesting.

Another example: McDonald’s fries may cause you to grow horns or raise your blood pressure. No one talks like that.

So I would toss it back to you: we are programmers but we have common sense. The author was clearly banking on something other than the technically accurate logical or.

Firstly, automobiles are really impressive.

Second, with that out the way, these cars are not playing the same game as horses… first, and quite obviously they have massive amounts of horsepower, which is kind of like giving a team of horses… many more horses. But also cars have an absolutely massive fuel capacity. Petrol is such an efficient store of chemical energy compared to hay and cars can store gallons of it.

I think if you give my horse the ability of 300 horses and fed it pure gasoline, I would be kind of embarrassed if it wasn’t able to win a horse race.

If you are running Linux, you can suspend using the following command, to re-initialize the GPU when resuming, which works around some ACPI bugs:

pm-suspend --quirk-vbe-post

I have a 1st-gen Lenovo X1 Yoga, and it is the only laptop series that has everything I want: an OLED display, a stylus, and a TrackPoint input. ACPI worked fine when I first bought it, and I can't remember if it's had one BIOS update or two, but after the most recent update, it sometimes won't wake from sleep. When that happens, he power LED fades on and off, no matter how many times I press the power button or close and open the lid. I have to hold the power button to force it off, then power it back on from a fresh boot.

Also, the Linux kernel added support for adjusting the OLED's brightness through ACPI, years ago, but it's never been supported on my laptop, and I have to resort to using xrandr to output dimmer images, which reduces bit depth.

My fan sometimes gets stuck on full speed, too.

Agreed. This and (sane) access to multi-threading. I want to be able to write a Rust application, compile to wasm and load it with

<html> <body> <div id="root"></div> <script type="application/wasm" src="./main.wasm"></script> </body> </html>

Would be great for high performance web applications and for contexts like browser extensions where the memory usage and performance drain is real when multiplied over n open tabs. I'm not sure how code splitting would work in the wasm world, however.

v8 could be optimized to reduce its memory footprint if it detects that no JavaScript is running - or wasm-only applications could use an engine like wasmer and bypass v8 entirely.

Another factor is that web technologies are used to write desktop applications via Electron/similar. This is probably because desktop APIs are terrible and not portable. First class wasm support in the web would translate to more efficient desktop applications (Slack, VSCode, Discord, etc) and perhaps less hate towards memory heavy electron applications.

Of course not! But usually, you can quantify metrics for quality, like uptime, lost transactions, response time, throughput etc. Then you can have accountability, and remediate. Even for other bugs, you can often reproduce and show clearly the impact. But in this case, other than internal benchmarks, you cannot really prove it. There is no accountability yet

They can still do the deep dive, that is absolutely convincing. They likely did: distracted before I could finish [work, unfortunately - incident of our own]

My criticism is it's 'puffy'. The 'scope and complexity' for a public postmortem is 'customer-facing'. Otherwise it's a tree/forest scenario.

One might say 'the lady doth protest too much'; this should be routine. It is, elsewhere: see Cloud, Web Hosting, PBX. Pick your decade.

> You have to actually review what's been uploaded to npm

Crates.io and several other popular package managers have the exact same problem. Submitted packages are essentially a blob of loose files with the source code being mere metadata provided by the uploader (or attacker!)

The logic behind this is that not every package comes from a source repository that is based on Git and there may not be a convenient and trustworthy "web link" back to the matching commit. Some SCM systems don't even have cryptographically hashed commits with the same level of "stability" as a Git commit id!

IMHO all such public package repositories should do their own Git hosting for the package file contents. I.e.: to publish you'd have to push your code to their repo instead of uploading files.

Ideally they should also scan all uploads in various ways, run reproducible builds for platforms where that makes sense, etc...

I wouldn't recommend a Creality to someone new to 3D printing. They can be a pain to work with. They're CHEAP, and there's plenty of aftermarket support, but that ends up turning the printer into a product for someone who sees the printer itself being a hobby, rather than the printer being merely an appliance that produces things.

Buying a Creality printer is like buying a hobby-grade RC car (ie, Traxxas, Team Associated, etc.). Decent out of the box, but you're likely going to be reaching for buying upgraded parts and it eventually becomes a Ship of Theseus.

I have an Ender 3 Pro, my list of upgrades:

- Replace the crappy flexible mat with PEI-coated flexsteel

- Filament runout detector

- Motherboard replacement (made flashing custom firmware 100x easier, and uses quieter stepper motor drivers)

- Automatic bed leveler

- Dual-gear extruder

- Customized firmware that changes the 3x3 bed leveling matrix to 7x7

- OctoPi

A decent printer will have half of these features already built in.

The most obvious one is the breakdown of trust in scientific research. A frequent discussion I would have with another statistics friend of mine was that that anti-vax crowd really isn't as off base as they are more popularly portrayed and if anything, the "trust the science!" rhetoric is more clearly incorrect.

Science should never be taught as dogmatic, but the reproducibility crisis has ultimately fostered a culture where one should not question "established" results (Kahneman famously proclaimed that one "must" accept the results of the unbelievable priming results in his famous book), especially if that one is interested in a long academic career.

The trouble is that some trust is necessary in communicating scientific observations and hypothesis to the general public. It's easy to blame the failure of the public to unify around Covid as based around cultural divides, but the truth is that skepticism around high stakes, hastily done science is well warranted. The trouble is that even when you can step through the research and see the conclusions are sound, the skepticism remains.

However, as someone that has spent a long career using data to understand the world, I suspect the harm directly caused by the wrong conclusions being reached is more minimal than one would think. This is largely because, despite lip service to "data driven decision making", science and statistics very rarely are the prime driver of any policy decision.

For starters, the DOM API is huge and expansive. Simply giving WASM the DOM means you are greatly expanding what the sandbox can do. That means lower friction when writing WASM with much much higher security risks.

But further, WASM is more than just a browser thing at this point. You might be running in an environment that has no DOM to speak of (think nodejs). Having this bolted on extension simply for ease of use means you now need to decide how and when you communicate its availability.

And the benefits just aren't there. You can create a DOM exposing library for WASM if you really want to (I believe a few already exist) but you end up with a "what's the point". If you are trying to make some sort of UX framework based on wasm then you probably don't want to actually expose the DOM, you want to expose the framework functions.
Ask HN: Dumbing Down Resume?
by SMAAART | 2025-09-17 22:13:20+00:00
Today I met with a supposedly top-notch career coach / executive coach.

We went over my resume, my linkedIN, my online presence, my experience, education, work....

In a nutshell I am an executive, in operations, with a long career in high-tech/Life Sciences.

I am very technical, a lot more technical than my peers. Besides the standard operations skills, I had deep knowledge and experience in "systems", and then, in the past decade or so, in data science/data analysis; and more recently AI/AI tools.

I have an online portfolio with tools that I built, papers I wrote, best practices, etc....

My present job search is not going well, kind of crickets so to speak.

So, the outcome of my session with my career coach was to dumb down my entire resume and collateral:

- downplay my title

- remove all the data skills, tools, and certification

- remove my online portfolio

- change my email from name(at)industry.ai to a generic gmail (he was very adamant about it)

He's probably right. Is he?

In a world where all companies/hiring managers are compaining that there are not qualified/good workers, here I am with a long career (yes I am old), stellar performance, proven and demostrable mastery of systems / data / AI tools (but I am not a SWE) and.... are all those skills too intimidating for a plan vanilla operations job, yet not enough for a real technical job?

What does HN think?

T.I.A.

I looked at a bambu printer a friend owns and it is pretty high quality engineering.

It stands on soft rubber feet so the whole machine has a low natural frequency (similar to the drum of a washing machine). This has the advantage that the high frequency movements of the motors/axes never resonate with the casing.

In the beginning it does a lot of tests and seems to also shake the machine to analyse the frequency behaviour.

À while ago, i went very hard on sport and even though i know before training that it would be hard, i would always reach some point during the training (usually around 40 minutes) where a feel good sensation, kind of god like, happen.

And you know, doing something hard when you know you’re going to get the high isn’t so terrible. But at some point it went away and since then I could not ever reach that.

I thought it was endorphine or dopamine kicking in, but why it would suddenly stop is weird.

That was years ago, still doing lot of sports and tried a few other since then, some I liked more, some I liked less, no difference whatsoever.

I’m thinking maybe I’m not pushing myself hard anymore but last summer I climbed Mont ventoux on bicycle 3 times during the same day. As a year old cyclist it was absolutely exhausting yet nothing at all. Just glad the suffering ended.

Also checked my hormones, everything fine.

That’s weird but I’m just wondering if that happened to someone else.

The relatively low headcount growth enables estimating values for the number of remote operators per vehicle. It takes four FTEs to fill one seat in the remote operation center 24/7.

If the ratio of remote operators to vehicles is 1:10, and the fleet size is 2500, that's 1000 FTEs. That's more than 5X the headcount growth.

If all of the headcount growth goes to remote operations, it would be one seat for 50 vehicles. I'd guess it's more like one to 100.

That fits with the relative rarity of seeing Waymos stopped waiting for instructions.

We're ripe for a situation where YouTube subpoenas ISPs MPAA 2.0 style over their users habitually accessing video and audio content streams without paying or validating through their ad chain. Google has every way from Sunday to identify users very accurately and I see it being an option on the table to ban accounts to the name, and potentially seek damages. RIAA did it for MP3s, MPAA for video content; rule of thirds?

Ultimately most sane people see ads as vomitpuke and this will continue to be a contention.
