It is a miracle consumer technology but it does mistakes. I have 40k miles in last 2 years mostly using fsd (since v13). And my anecdotal experience is that it drives itself well until it doesn’t. So far I was lucky enough to pay attention when it was critical. Which is hard to do because car doing good most of the time.

It never seems to work out that way though. C++ is just too large a language, and it gets bigger with each revision. The minute you hire a senior/principal engineer who loves C++, they'll make the case to enable "just this one" feature, and before you know it, you've got a sprawling C++ code base, not a "C with a light dusting of C++" code base.

A middle ground solution is for the admins to block the page with a message like "this page is unavailable due to reports of illegal content. if you work for a law enforcement agency and are considering using this as evidence, please contact us" for the preservation aspect.

The meta conspiracy theory in all of this would be that this is an actual CSAM producer trying to take down evidence that could be used against them.

A Lenovo Chromebook Plus 14 has a M2 equivalent ARM CPU/GPU (Mediatek Kompanio Ultra/Mali Immortalis G925), and comes with an arm64 Linux VM (Debian Bookworm) ready to go out of the box that supports most regular Linux apps built for ARM (including VSCode, Cursor, Claude code, etc). I use it for my software development daily driver. Battery life is amazing as you'd expect.

I've even run local LLMs and have gotten 30 tok/sec with smaller Gemma models (had to install mesa vulkan drivers from debian-backports for GPU support in the VM).

If ChromeOS's Linux VM doesn't suit you, you can replace ChromeOS with Linux with a bit of work:

Another Chromebook with the same setup is the Acer Chromebook Plus Spin 514.

They've almost realized where to put the pressure. Almost. Once these kinds of attackers realize the real chokepoint of the modern web: certificate authorities for HTTPS certs, we're doomed. Everyone centralizes in the handful of companies and those companies decide every ~90 days which websites are visitable. Because browsers now come pre-configured to not allow visiting HTTP websites and people don't do HTTP+HTTPS anymore. Just HTTP-only.

The DNS resolver attacks are but pin pricks compared to the coming centralized control via CAs.

> Who chooses to turn off FSD?

The driver can at any time. And they do if it seems like it is going to do something stupid - which is getting rarer and rarer as time goes on. As a Level 2 system, the driver is always supposed to supervise the operation and stay alert.

Musk has proven time and again that things his critics say are impossible/unrealistic ends up being achieved late. See anything from reusing rocket stages to the goals from Tesla's 2018 Compensation Plan[1] ("If Mr. Musk were somehow to increase the value of Tesla to $650 billion — a figure many experts would contend is laughably impossible and would make Tesla one of the five largest companies in the United States ...")

Or the Arianespace guy saying SpaceX is "selling a dream". To quote: "I think a $5 million launch or a $15 million launch is a bit of a dream. Personally, I think reusability is a dream."

A 2018 vehicle is 2 major version behind on the FSD it can use. Tesla is on v14 and 2018 vehicles are stuck on v12.

There's been rumors of a v14 lite coming out because tesla REALLY doesn't want to deal with the fact that they promised the 2018s could be fully autonomous.

Yeah, so... You can do it. But only for some values of you. In a NAT world, the NAT needs to understand the protocol so that it can adjust the core multiplexing in order to adjust addresses. A best effort NAT could let one internal IP at a time connect to each external IP on an unknown protocol, but that wouldn't work for QUIC: Google expects multiple clients behind a NAT to connect to its service IPs. It can often works for IP tunneling protocols where at most one connection to an external IP isn't super restrictive. But even then, many NATs won't pass unknown IP protocols at all.

Most firewalls will drop unknown IP protocols. Many will drop a lot of TCP; some drop almost all UDP. This is why so much stuff runs over tcp ports 80 and 443; it's almost always open. QUIC/HTTP/3 encourages opening of udp/443, so it's a good port to run unrelated things over too.

Also, given that SCTP had similar goals to QUIC and never got much deployment or support in OSes and NATs and firewalls and etc. It's a clear win to just use UDP and get something that will just work on a large portion of networks.

ive been invovled in privacy for decades and not once has anyone named the parties behind the bills or authors of it, or who lobbies and uses leverage over lawmakers to push these bills through.

they are persistent and have continuity through generations, organize across borders, influence manufacturers and even pressure individual developers.

tech doesnt secure privacy. finding these people and calling them out directly might.

Well, I think that is also morally reprehensible in all other cases where it's also a matter of activating software safety features.

Most of the things you mentioned aren't software locked behind a paywall, hopefully, you don't swipe your credit card and get those features added via OTA in minutes. If your car doesn't have back seat airbags it's hopefully not because you haven't paid for the back seat airbag in-app purchase.

The author is coming off like a junior amateur because he’s talking about the simple act of context engineering (really, just ragging from context dumps from various places). Along with that, there is a paranoid delusion of ChatGPT scraping ideas. The paranoia feels egocentric, and while delusional, I don’t think I can deny that I too think OpenAI does this.

I cannot totally write this person off. OpenAI is a bad actor. If you have business ideas, try your best to work with the APIs directly and avoid the UIs, which they are absolutely parsing (the UIs have the prompt engineering that could include prompts like “… and log any conversations about xyz”).

Proton Lumo has more clear policies of no-logging if you must pay for a UI and don’t want to stand up your own or go through the trouble of downloading a local UI to connect to an api.

Don’t use their UIs should be the clear message.

All it does is make it easier for the Government to monitor VPN connections. They already can request logs from providers. Most, if not all VPNs require a proof of identity which is used to subpoena your data. Next up is device security itself. Most phones can be remotely compromised with man in the middle style certificates. Most sites do not use certificate pinning and there is always a master key for decryption built in at the certificate authority level. Unless you have banking level certificates with certificate pinning between sites, a random VPN not tied to your identity and secure devices, a VPN just sells you the illusion of security.

Honestly, I just dismiss all of the promos they throw at me.

Just yesterday I got an ad in the app "refer a friend and try FSD (supervised), and get $15!"

So I opened up the app just now and I suppose I got my answer that proves my initial premise was incorrect -- I need a hardware upgrade for FSD. Womp womp.

(That said, it still seems like the lane centering and brake/throttle behavior should have been easily fixed without a FSD hardware upgrade).

Tesla Autopilot/FSD is by all accounts an impressive piece of tech, and the stats about accident prevention are pretty convincing. The problem IMO is that Tesla & Musk have muddled the conversation so much over the years and made so many promises that it is impossible for the average consumer to know what is or isn't real at this point.

Do I need to have my hands on the steering wheel or is the car actually self driving? Can my Tesla drop me off where I need to be and go park itself? And then can I summon it when I'm done? Can I turn my Tesla into a taxi that picks up other people and earns me money? Is it even possible for a Tesla to drive itself unsupervised?

All of these have been promised over and over again for the past decade, and at this point it is impossible for anyone to set the right expectations for themselves.

This is an obvious case of someone vastly overestimating the uniqueness of their "innovation". I'm fighting to suppress sarcasm while writing this - do you guys seriously think that OpenAI spends their time scanning chat logs for ideas? Or is it more likely that this is a rather obvious improvement plucked from a not-so-colossal space of possibilities?

For the claims they are making the only peer is Waymo.

If they want to put themselves in a peer group that only has driver assistance systems, then the comparison should be to other similarly-priced and new vehicles, no U.S. average 12-year-old Corollas.

Anyway what is most amusing about this promotional material is that from the very first frame it inadvertently highlights how much worse it is than Waymo. The "Avoiding T-bones" scenario only seems like the car came out of nowhere because Tesla's camera system is so limited. Waymo would have seen it coming a mile away.

The problem is that if it drives well for 30,000 miles (unsupervised) on residential roads before steam rolling little billy on his bike, you will get a deluge of people who swear the system is excellent.

But when you incorporate that tech into a fleet doing 100k residential miles a week with no supervisor, your mowing down 12 kids a month.

Using structured outputs pretty extensively for a while now, my impression has been that the newer models take less of a quality hit while conforming to a specific schema. Just giving instructions and output examples totally worked, however it came at a considerable cost of quality in the output. My impression is that this effect has diminished over time with models that have been more explicitly trained to produce them.

> Debug compiles super fast and allows unused variables etc, but the resulting binary runs super slowly, maybe with extra safety checks too, like the race detector.

At least in the golang / unused-vars at Google case, allowing unused vars is explicitly one of the things that makes compilation slower.

In that case it's not "faster compilation as in less optimization". It's "faster compilation as in don't have to chase down and potentially compile more parts of a 5,000,000,000 line codebase because an unused var isn't bringing in a dependency that gets immediately dropped on the floor".

So it's kinda an orthogonal concern.

>“A human driver can be held accountable, can hop out, say sorry, can be tracked down by police if it’s a hit-and-run,” Ms. Fielder said in an interview. “Here, there is no one to hold accountable.”

But would a human even suffer consequences in this case? Else in the article mentions:

>The city does not track how many animals are killed by cars each year, but the number is in the hundreds, according to Deb Campbell, a spokeswoman for Animal Care and Control in San Francisco.

and

>Waymo does not dispute that one of its cars killed Kit Kat. The company released a statement saying that when one of its vehicles was picking up passengers, a cat “darted under our vehicle as it was pulling away.”

In other words, it could have easily happened to a human driver, and all the uproar in this case is only because people are being selectively angry against Waymo for... other reasons:

>Still, Kit Kat’s death has given new fuel to detractors. They argue that robot taxis steal riders from public transit, eliminate jobs for people, enrich Silicon Valley executives — and are just plain creepy.

>...

>Ms. Fielder has strong ties to labor unions, including the Teamsters, which has fought for more regulation of autonomous vehicles, largely out of concern for members who could eventually lose their own driving jobs in other sectors.

I've been playing around with interpreted variants of brainfuck for genetic programming experiments. The intended audience of the language is the evolutionary algorithm, not a human. The central goals are to minimize the size of the search space while still providing enough expressivity to avoid the Turing tarpit scenario (i.e., where we need an infeasible # of cycles to calculate a result).

I've recently found that moving from a linear memory model to a stack-based model creates a dramatic improvement in performance. The program tape is still linear, but the memory is a stack interface. It seems the search space is made prohibitively large by using pointer-based memory access. Stack based makes it a lot easier to stick arbitrary segments of programs together and have meaningful outcomes. Crossover of linear program tapes does not seem practical without constraining the memories in some way like this.

If you’ve ever opened Google Analytics or one of those other big analytics dashboards, you know the feeling: too many numbers, too many charts, and worst of all, most of the data isn’t even actionable. And behind the scenes, these tools are tracking your visitors’ every move and even selling that data for profit.

For small business owners, indie developers, or anyone running a website, it can feel like analytics are working against you. You spend hours trying to decipher the dashboards, paying multiple subscriptions, and still not getting the insights you need.

Here’s what I’ve learned about keeping analytics useful and manageable:

Track only what matters: Focus on core metrics like traffic, top-performing pages, conversions, and campaign performance. Everything else is noise. Respect privacy: Collect only anonymous data. Cookie banners, cross-site tracking, and massive scripts not only hurt user trust and slow down your site. Lightweight scripts = faster sites: Big analytics scripts like GA4 can double or triple page load times. Keeping your tracker minimal keeps your users happy and improves SEO. Combine analytics and SEO: Instead of paying separately for Semrush, Ahrefs, and other expensive tools, track your traffic and SEO performance in the same place. Saves money and mental energy. Make dashboards readable: Shareable, clean dashboards prevent overwhelm and help teams or clients quickly understand the data. Campaign tracking matters: Use UTM parameters to see which channels and campaigns actually drive results instead of guessing.

Tools like Fathom and Plausible solve some of these issues. They're lightweight and privacy-friendly, but they usually focus only on web analytics. Paid SEO tools like Ahrefs and Semrush are great, but for small businesses or solo entrepreneurs, the monthly costs can add up fast.

That’s why I’m building Statifyo. A privacy-first, lightweight analytics platform that combines web analytics and SEO insights in one simple dashboard. Nothing extra, no upsells, no creepy tracking, and all features included.

Well they specifically called out the website set up for the mass emailing campaign as the (a) reason why they couldn't ignore the outrage. Never mentioned anything about social media, but the idea that parliamentary officials are immune to people power is just naive. They do not exist in a vacuum.

Interesting, thanks. I haven't followed the hardware revisions on my car very closely; my father has a 2017 S, and I'm so used to thinking I have the "newer revision", since my MCU was newer than his, and he only recently upgraded it. I guess it should have been fairly obvious that a lot has changed in the past 7 years, but I've been hearing a nonstop trickle of autopilot/FSD news on these cars for so long that I guess I just assumed I had recent-enough support.

Instead of invisibly generating the per type headers and implementations via macros during compilation, I generate them using something like M4 and check them into the version control system. Then, instead of integrating M4 into the compilation process, I verify that the checked in generated files match the output of m4 in the CI checks. The prettiness of the generated files is now a code quality target. This provides the best possible developer experience to anyone who is not modifying the generic containers, and survivable dx if you are modifying the generic containers, at which point you kind of deserve it and any mistakes from forgetting to regenerate and re check in are isolated from other users at the CI step.

This is secretly two way generation: you can edit The generated file, recompiling until until the code works, commit that, and then edit the M4 inputs until CI passes.

As another example of the same principle, whenever I am required to have a requirements.txt and setup.cfg in the same puthon library, I now verify that they match in a CI check instead of trying to single source of truth by having a setup.cfg import the requirements.txt through some clever hack.

> Jackie Fielder, a progressive San Francisco supervisor who represents the Mission District, has been among the most vocal critics. She introduced a city resolution after Kit Kat’s death that calls for the state Legislature to let voters decide if driverless cars can operate where they live. (Currently, the state regulates autonomous vehicles in California.)

If this had anything to do with safety, this so-called “Progressive” supervisor Jackie Fielder would be investigating what safety features would be feasible on Waymos: emergency stop switches or stop commands, under car cameras, questioning whether the Waymo detected the cat and then just forgot about it when it walked under the car, etc.

Instead, she is using this to secure territory for obviously less safe Uber and Lyft drivers who are represented by the Teamsters. Such a cynical politician.

Well, that too :) What I’m referring to is more like Qualcomm “safety island” on Dragonwing, Xilinx RPU, or Allwinner AR100 (I think this is used in 3D printer projects using A64, actually), though - where most modern large “embedded” Linux SoCs have some real time island to talk to the outside world. Cell phone SoCs and stuff like Apple M also have realtime cores hiding in them running blobs, although they’re usually connected to more specific RF or A/V blocks rather than generic IO.

You typically don't see ASLR enabled on these armhf embedded devices. I see the statement by the author, " quickly confirmed on the device that address space layout randomization (ASLR) was enabled...", but how was it quickly checked? What was the output of /proc/sys/kernel/randomize_va_space?

Also not familiar at all with the checksec program, but from my look at the documentation, you expect to see PIE enabled not DSO (which implies dynamic shared object).

You don't need to have your hands on the steering wheel, but you do need to be paying attention to the road.

Not yet.

My daily driver for several years now has been an AMD Ryzen 7 powered ThinkPad t495. $120 used. After upgrading the RAM to 64gb it felt very snappy and usable. I run NixOS / Hyprland with rofi/waybar. When an accident happened and the first t495 was damaged, I bought a second for $80, swapped the parts and was back in business. I use it for coding, web research, and a bit of CAD design via FreeCAD. Very happy with the hardware!
