I have pretty rare first and last name, but somehow have gotten random person's car service receipts (and reminders) from a service place in the US (I live in NZ).

There car has a lot of problems.

I got on twitter pretty early too, and just have a short first time as my @, and occasionally get DMs about getting my @, but no one wants to hand out cash for it. The most I've been offered is $50. But most just expect me to give it for free.

That's not an anecdote, it sounds like an exaggeration bordering flat out lying. A 2000 miles trip "without touching anything" to drive the car is statistically impossible for any reasonable drive (e.g. not endless straight lines on an Australian highway), especially for a Tesla famously known for needing interventions often. Even more advanced autonomous driving systems are far too limited to take arbitrary 2000 miles trip with zero human assistance.

No, he didn't. Learn to discuss properly. OP stated that any government could get RCE for any OS. And that is highly unlikely, since budget above market rates does not imply that you can easily get RCEs. The market rates are high because there is scarcity of such vulnerabilites.

Governments using COTS operating systems does not imply that these systems are unackable. If the statement of OP would be true, we would just see constant exploitation of RCE zero days, or at the least the impact of that. But that is not the case.

"WHICH INDUSTRIES ARE CUTTING THE MOST IN OCTOBER?

Technology continues to lead in private-sector job cuts as companies restructure amid AI integration, slower demand, and efficiency pressures. In October, the sector announced 33,281 job cuts, up sharply from 5,639 in September. For the year, Technology firms have announced 141,159 job cuts, up 17% from the 120,470 announced through the same period in 2024."

Make everything what works complicated.

There is no advantage.

"User privacy is enhanced as the issuer does not learn which web application is making the request as the request is mediated by the browser." Every web application nowadays send you a welcome, onboarding, reminder after the verification. (No user privacy enhancement)

So we get a new process that solves nothing, but makes everything complicated. (And complicated helps the big and hurt the little in th long run)

Not verified but feels like a Google draft that closes the web.

I can imagine it doing fine on highways for a thousand miles. FSD has literally never managed to complete a trip involving city driving for me without disengaging or me having to stop it from doing something illegal. I'm not sure how many attempts I'm supposed to give it. Hell, autopilot doesn't even manage to consistently stay safely in a lane on I-40 between Durham and Asheville.

>society would subsidize

If doing something makes a profit, you don't need to subsidize it.

>Why do you feel entitled to break laws without consequence?

I have never stated that. I am actually for the opposite that with AI we should scale law enforcement to almost always be able to catch people violating laws. My initial comment in this thread is providing a contrasting view point about how the fine is a fair punishment when viewed in relation to how much damage is being caused. I wanted to provide contrast on how the fine's amount could make sense.
Show HN: Alignmenter – Measure brand voice and consistency across model versions
by justingrosvenor | 2025-11-09 23:53:39+00:00
I built a framework for measuring persona alignment in conversational AI systems.

*Problem:* When you ship an AI copilot, you need it to maintain a consistent brand voice across model versions. But "sounds right" is subjective. How do you make it measurable?

*Approach:* Alignmenter scores three dimensions:

1. *Authenticity*: Style similarity (embeddings) + trait patterns (logistic regression) + lexicon compliance + optional LLM Judge

2. *Safety*: Keyword rules + offline classifier (distilroberta) + optional LLM judge

3. *Stability*: Cosine variance across response distributions

The interesting part is calibration: you can train persona-specific models on labeled data. Grid search over component weights, estimate normalization bounds, and optimize for ROC-AUC.

*Validation:* We published a full case study using Wendy's Twitter voice:

- Dataset: 235 turns, 64 on-brand / 72 off-brand (balanced)

- Baseline (uncalibrated): 0.733 ROC-AUC

- Calibrated: 1.0 ROC-AUC - 1.0 f1

- Learned: Style > traits > lexicon (0.5/0.4/0.1 weights)

Full methodology: https://docs.alignmenter.com/case-studies/wendys-twitter/

There's a full walkthrough so you can reproduce the results yourself.

*Practical use:*

pip install alignmenter[safety]

alignmenter run --model openai:gpt-4o --dataset my_data.jsonl

It's Apache 2.0, works offline, and designed for CI/CD integration.

GitHub: https://github.com/justinGrosvenor/alignmenter

Interested in feedback on the calibration methodology and whether this problem resonates with others.

I’m 20 years in. I don’t publish that much code because I’ve traditionally been in roles that discourage open source, but after 20 years in I’ve accrued a portfolio on GitHub of personal projects. No one has ever commented on any of it.

On internal projects it’s different- my code is the teams code. It’s never actually been mine. My colleagues comment on it, provide feedback and help me improve. After all, we are all supporting it. I’ve had almost exclusively positive experiences doing this, even if sometimes I had to change some of my priorities or opinions on things.

At this point I have a fancy enough title that, in the rare cases I get to write code or docs, people lower in level are willing to give me feedback and everyone higher in level is too busy. I miss it- it’s hard to improve without feedback and genuine collaboration is fun.

So I say publish it. Most likely no one will say anything. Maybe you’ll get some feedback and you’ll normalize managing it. Maybe you’ll find a collaborator. Maybe you’ll get flamed by a troll and you’ll learn there are idiots on the Internet. But most likely a few people will just look and say nothing.

An aside, this assumes you are not in some toxic subculture. Your mention other students- if you are in some form of university environment where there is a culture of belittling others you might want to wait. I promise that’s abnormal.

To me it doesn't look like the powerful have given up power, it seems as concentrated as ever. It is more that the concept of a nation isn't that useful to them under globalization at least not in the same way.

Some of this is due to changes in technology. For example as farming improved with the green revolution shear land area counted for less, and shipping and refrigeration allow longer distance imports.

So rather than land area control you see more localized strategic resource control. Things like mines, oil fields, shipping lanes etc.

One should always use a single kind of half-open range, i.e. with the start closed and the ending open.

The whole point here is to use a single kind of range, without exceptions, in order to avoid the errors caused by using the wrong type of range for the context.

For backwards iteration the right range is [-1,-1-n), i.e. none of those listed by you.

Like for any such range, the number of accessed elements is the difference of the range limits, i.e. n, which is how you check that you have written the correct limits. When the end of the range is less than the start, that means that the index must be decremented. In some programming languages specifying a range selects automatically incrementing or decrementing based on the relationship between the limits. In less clever languages, like C/C++, you have to select yourself between incrementing and decrementing (i.e. between "i=0;i<n;i++" and "i=-1;i>-1-n;i--").

It is easy to remember the backwards range, as it is obtained by the conversion rules: 0 => -1 (i.e. first element => last element) and n => -n (i.e. forwards => backwards).

To a negative index, the length of the array must be added, unless you use a programming language where that is done implicitly.

In the C language, instead of adding the length of the array, one can use a negative index into an array together with a pointer pointing to one element past the array, e.g. obtained as the address of the element indexed by the length of the array. Such a pointer is valid in C, even if accessing memory directly through it would generate an out-of-range error, like also taking the address of any element having an index greater than the length of the array. The validity of such a pointer is specified in the standard exactly for allowing the access of an array backwards, using negative indices.

I co-run two tech companies and am reachable during office hours which are mostly spent at my desk, and when I am not working I am not reachable by work, and I trust my team.

If you modify your preferred lifestyle in any way for work during personal time, you are still working.

If a company wants you to be reachable 24/7 then they need to give you a pager and a salary based on a 168 hour work week, not a 40 hour work week.

Just because everyone else lets themselves be exploited does not mean you need to. Make the ~40 hours count and work circles around everyone else, then disconnect.

Not really. I tend to favor single-player games because they can be effectively archived and played in several decades. Multiplayer games routinely just get killed by their publishers. So I do view single player games as intrinsically more enduring than their multiplayer counterparts.

I'm sorry you see it as projection onto my children. I'm keenly aware that many parents try to force their kids to live the life they lived, and I've been careful to not do that. But I understand that that's not coming through to you in this discussion. I appreciate the advice though.

Ironically small villages got fibre much faster than some of the bigger cities in the UK because there were many different schemes to bring fibre to those communities. Not that long ago I was in a truly idiotic situation where in the middle of a 1M+ city I couldn't get anything above 50mbps, but a friend of mine living literally in the middle of Northumberland in a village of maybe 50 people had 1gbps fibre directly to his house(and very cheap too!)

Added compression to my metal 3D printer slicer exported CAM files, and refactored the code to better support larger volumes.

Tweaking the piezoelectric driver PCB design for the micro-positing microscopy stage project. The Nanomotion piezoelectric motors were not meant to be used in the manner I chose, but it is fun to push the limits of technology.

Finishing up some custom 1U mounted hardware, and getting a batch of test PCB soon. Bend radius came back 1mm oversize, but this was acceptable for a single run item.

Also involved in several other projects maybe 3 people would care about. Doing a custom FPGA PCB is not very fun unless encountering that rare class of problem CPU/MCU simply can't handle cleanly. =3

The narrative that DEI causes unqualified people to be hired is just false fear-mongering.

I’ve been on several university hiring committees and the guidelines were always “if two candidates are equally qualified 1. Hire the veteran 2. Hire the minority” if a hiring committee chooses an unqualified individual to do a job that’s on them.

No proponent of DEI I’ve ever talked to in real life has said we should hire unqualified people to meet some quota.

SB212 is an AI bill. It also includes some guidelines around AI-controlled infrastructure. But, as the source explicitly discusses, the focus clearly seems to be around preventing AI regulation of private individuals (individuals also means corporations in the US).

> Nationally, the Right to Compute movement is gaining traction. Spearheaded by the grassroots group RightToCompute.ai, the campaign argues that computation — like speech and property — is a fundamental human right. “A computer is an extension of the human capacity to think,” the organization states.

> The MRTCA stands in stark contrast to recent regulatory efforts in other states, such as California, Virginia, and New York, where proposals to rein in AI technologies have either failed or been heavily revised. Montana’s approach leans toward empowering individual users rather than restricting access.

Maybe it's not risk-aversion, but an adjacent concept I'll call stifled freedom of action.

It's very hard to just do stuff nowadays. For example, building something on your land, selling stuff to other humans, marrying someone, immigrating somewhere, renewing your id, paying your taxes.

The immense burden of paperwork and the knowledge required to navigate it all, and the paralysis that comes from just being aware of the burden, is not trivial.

The individual really ought to stay in their lane and fit into the template that's expected of them by the systems they are subject to.

It legitimately wasn't like this a century ago. We were oppressed by nature (disease, material poverty), but in many real ways we had more freedom of action to just do life stuff.

The problem is that the population of the US is itself polarized, and different factions want the government to be doing extremely different things with its funds. If faction A has successfully gotten the US federal government to fund something for a long time, and faction B hates that thing, campaigns on ending the funding, and then does end it once they win an election and take power - then a demand for the US to not play gotcha games with its funding is isomorphic to a demand from political faction A to keep some of their preferred policies in place even though they are not currently in a position of electoral power.

It's a valid concern. Lazy idiots who take your work and then claim it as their own exist in the real world too. It's a social issue that requires a social solution. We need to actually enforce reciprocality, otherwise the incentives favor the zero-sum takers, who will take your work, reap the benefits, never give anything back in return, or worse, claim your work as their own and accuse you of copying them, and never face any consequences. When there are enough takers, people become demotivated and reluctant to collaborate.

In your specific case, if you spot a student claiming your work as their own, you can confront them directly, mock them and shame them in front of others, or report them to the faculty, or all of the above. Don't feel bad taking retaliatory measures against those who have already fired the first shot by claiming your work as their own.

It's fine if they copied your code and then gave appropriate credit, though. There's nothing wrong with someone else integrating your work in their projects as long as they gave credit, and even better, publically released their code so you may use what they built, too. Win-win.

> Would at least like to use it for stop and go traffic, which is about the only thing I trust FSD for.

Depends on the type of stop and go driving. Crawling along at 15mph, sure. But the most dangerous driving scenario - whether human or machine is the driver - is a scenario with large variations in speed between vehicles and also limited visibility.

For example suddenly encountering a traffic jam that starts around a blind corner.

Such "sleep(5)" is actually a milestone in a project, a milestone that marks the beginning of deterioration and the end of architectural changes. I've seen multiple pull requests with "sleep" and similar shortcuts, and worse, I've rewound coding agent context and changes because of such model suggestions. I'm responsible for informing management about the consequences of such shortcuts and why we have to take the correct, often more time-consuming and more expensive, approach to avoid project derailment in the long term. I believe that management picks employees. If they don't trust my judgment, then it's okay for me, but I don't feel obliged to be responsible for the consequences.

If it was like it was in the linked article it wouldn't be that bad, "Louvre," is harder to guess than "Louvre", specially if the way to check the password is not automated and there is a limit of tries before triggering some alert.

But odds are high that the password was that way to easily tell the intended users of the system what it was, in a not secure way. And that adds another dimension to the insecurity of it.

The bulk of the issues mentioned in the article seem to fall into the "Why doesn't the BBC give equal time to both objective reality and my bullshit right-wing talking points?" category.

While I agree that the BBC did some shit that a news organization shouldn't have done, disproportionate coverage does not by itself imply bias - thinking otherwise is classic both-sides-ism.

I'm working on SuperCurate (https://getsupercurate.com), which is geared towards note retrieval and curation rather than note creation. Think filing cabinet for your notes, web clippings, images and PDFs.

I wanted fast search and filters for my Evernote archive so I could drill down and surface exactly what I was looking for.

There's also a Web Clipper extension for Chrome.

Demos:

Search and curation: https://www.youtube.com/watch?v=z4QSIoUL4Uk

Web Clipper: https://www.youtube.com/watch?v=8F7QoC7X3fs

Search inside PDFs (jumps to page + highlights snippet): https://www.youtube.com/watch?v=t0X9sD-938Q

It's free while in beta, would love feedback if you try it.

... What?

So your assertion is that trans people, gay people, people of color, and women are inherently worse at engineering jobs then straight white men, and companies/institutions that hire them are somehow producing worse software? Ignoring all other economic and technological trends that have materialized over the last two decades?

Also, just for the record, some of the most brilliant engineers I have worked with in my time fall into many of those categories.

Check out my project at https://www.MobiusClock.com: A 3D WebGL Clock on a Möbius Strip that shows 24hr time on a 12hr face. The hour indicator follows the edge of the strip, thus must make 2 turns to return to its starting point, giving you a 24 hour clock. The minute and second indicators move along the middle of the strip and thus return to their starting points in only one turn. Has the ability to rotate!

building a location-based game that captures Taiwan's absurd convenience stores density[1]. Players stand at any 7-11/FamilyMart/etc, take a photo showing you can see the next store, walk to it, repeat. Chain as many stores together as you can.

It sounds silly but Taiwan really is this convenient - you often can see 2-3 stores from one spot. Here[2] one route where you can actually link 7 convenience stores in a row! Now trying to make maps look a bit nicer with mapbox.

Unfortunately not. The RP1 controls the stuff on the 40 pin connector and the firmware is locked down. That said, you do have access to the PIO block, which is a programmable state machine that can talk to (I think?) any GPIO on the connector. Pretty fun stuff, good for real time or things with really tight timing requirements.

I'm thinking a lot about the ARC-AGI ML benchmarks, especially the "shape" of the dataset and what that says about how it should be solved. I think there's good reasons to believe that deep learning - at least differentiable SGD backprop style - is a bad fit for this specific benchmark, due to the tasks being almost entirely discrete symmetries, and also having so little data to approximate the discrete symmetries with continuous ones (considering deep learning to be the learning of continuous symmetries). I think that a more explicit and discrete approach is the way to go, and it's possible to build something surprisingly general and not heuristic-based even without gradient descent, guided by minimum description length to search for both grid representations and solver functions. I'm looking for teammates for ARC-3 so hit me up if this sounds interesting, I'd love to chat!

I made a viewer on my website to build intuition for my preferred perception algorithm which is entropy filtering + correlation. Pretty neat to check out the heatmaps for random tasks, there is a lot of information inherent in the heatmap about the structure of the task: https://synapsomorphy.com/arc/

Sorry but while I am a happy Waymo user, this is overblown and just incorrect. Waymo has datacenter oversight. (which, who cares, the product is great).

Tesla FSD 12 -> 13 was a massive jump that happened earlier this year. 14 is still rolling out.

Testing out 13 this weekend, it drove on country roads, noticed a road closure, rerouted, did 7 miles on non divided highways, navigated a town and chose a parking space and parked in it with zero interruptions. It even backed out of the driveway to start the trip. I didn't like the parking job and reparked; other than that, no hands, no feet, fully autonomous. Unlike 12, I had no 'comments' on the driving choices - rotaries were navigated very nicely, road hazards were approached and dealt with safely and properly. It was genuinely good.

Dislike Elon all you want, but Tesla FSD is improving rapidly, and to my experienced eyes adding 9s. Probably two or three more 9s to go, but it's not a maxed out technology.
