The simplest solution is for `std::mutex` to provide a simple, efficient mutex which is a good choice for almost any program. And it does. Niche programs can pull in a crate.

I doubt `parking_lot` would have been broadly used—maybe wouldn't even have been written—if `std` had this implementation from the start.

What specifically in this comparison made you think that `parking_lot` is broadly needed? They had to work pretty hard to find a scenario in which `parking_lot` did much better in any performance metrics. And as I alluded to in another comment, `parking_lot::Mutex<InnerFoo>` doesn't have a size advantage over `std::mutex::Mutex<InnerFoo>` when `InnerFoo` has word alignment. That's the most common situation, I think.

If I were to make a wishlist of features for `std::mutex` to just have, it wouldn't be anything `parking_lot` offers. It'd be stuff like the lock contention monitoring that the (C++) `absl::Mutex` has. (And at least on some platforms you can do a decent job of monitoring this with `std::mutex` by monitoring the underlying futex activity.)

I personally jumped ship from Claude to OpenAI due to the rate-limiting in Claude, and have no intention of coming back unless I get convinced that the new limits are at least double of what they were when I left.

Even if the code generated by Claude is slightly better, with GPT, I can send as many requests as I want and have no fear or running into any limit, so I feel free to experiment and screw up if necessary.

3 units. 2 unplanned. One being a 7 month outage.

Just like during the energy crisis Sweden had another 7 month outage. With the worst week of all with the winter peak consumption happening with 2 reactors having outages.

But it is much easier to pretend that the capacity factor over the lifetime applies and then cry about renewables eating their lunch.

Hahahaha if that ever happens. The government seems to like the idea of nuclear power but not politically bearing the costs of tens of billions in handouts.

Now they’ve soon spent four years dallying without any real progress and the next election is coming up in September.

The question you need to answer is:

Why should a home owner with rooftop solar and a home storage buy 18 cents/kWh + backup (you know, 2 out of 6 reactors having outages when needed the most) when their rooftop solar or home storage delivers?

I'm pretty sure this isn't happening with the API versions as much as with the "pro plan" (loss leader priced) routers. I imagine that there are others like me working on hard problems for long periods with the model setting pegged to high. Why wouldn't the companies throttle us?

It could even just be that they just apply simple rate limits and that this degrades the effectiveness of the feedback loop between the person and the model. If I have to wait 20 minutes for GPT-5.1-codex-max medium to look at `git diff` and give a paltry and inaccurate summary (yes this is where things are at for me right now, all this week) it's not going to be productive.

Lol, in 3rd grade algebra, a teacher called 2 of us in for cheating. She had us take the test again, I got the same exact horribly failing score (a 38%) and the cheater got a better score, so the teacher then knew who the cheater was. He just chose the wrong classmate to cheat of of.

The latest MCP specifications (2025-06-18+) introduced crucial enhancements like support for Structured Content and the Output Schema.

Smolagents makes use of this and handles tool output as objects (e.g. dict). Is this what you are thinking about?

Distribution maintainers who do the backports do not necessarily have access to this kind of information. My impression is that open sharing of in-the-wild exploits isn't something that happens regularly anymore (if it ever did), but I'm very much out of the loop these days.

And access to the reproducer is merely a replacement for lack of public vulnerability-to-commit mapping for software that has a public version control repository.

This is great. Sonnet 4.5 has degraded terribly.

I can get some useful stuff from a clean context in the web ui but the cli is just useless.

Opus is far superiour.

Today sonnet 4.5 suggested to verify remote state file presence by creating an empty one locally and copy it to the remote backend. Da fuq? University level programmer my a$$.

And it seems like it has degraded this last month.

I keep getting braindead suggestions and code that looks like it came from a random word generator.

I swear it was not that awful a couple of months ago.

Opus cap has been an issue, happy to change and I really hope the nerf rumours are just that. Undounded rumours and the defradation has a valid root cause

But honestly sonnet 4.5 has started to act like a smoking pile of sh**t

You are not really factoring in all the work on the hardware, much of the software, and the entirety of the financing, which is being done by Eric and the Core Devices team.

If Rebble wants to take the risk and put out a smartwatch, there is nothing stopping them. Infact all of the open sourcing work Core Devices has done gives them a good starting point.

> The nerf is psychologial, not actual

Once I tested this, I gave the same task for a model after the release and a couple weeks later. In the first attempt it produced a well-written code that worked beautifully, I started to worry about the jobs of the software engineers. Second attempt was a nightmare, like a butcher acting as a junior developer performing a surgery on a horse.

Is this empirical evidence?

And this is not only my experience.

Calling this phychological is gaslighting.

I don't disagree that AI psychosis is real, I've met people who believed that they were going to publish at Neurips due to the nonsense ChatGPT told them, that believed that the UI mockup that claude gave then were actually producing insights into it's inner workings instead of just being blinking SVGs, and I even encountered someone participating at a startup event with an Idea that I'm 100% is AI slop.

My point was just that the interaction I had from r/myboyfriendisai wans't one of those delusional ones. For that I would take r/artificialsentience as a much better example. That place is absolutely nuts.
Costs of AI That Are Eating Your Budget (and How to Fix Them)
by buttersmoothAI | 2025-11-24 21:07:02+00:00
I'm the Director of Marketing & Sales at AiGuardian. After analyzing hundreds of AI implementations, I've identified 5 hidden costs that most teams don't realize are eating their budget:

*1. Token Overconsumption* - Problem: Most teams don't optimize token usage - Cost: 40-60% overspending on API calls - Solution: Intelligent chunking, summarization, caching - Impact: Companies using TokenGuard reduce costs by 30-70%

*2. Context Drift* - Problem: Context breaks mid-conversation, requiring re-prompting - Cost: Broken user experiences, support tickets, re-engineering - Solution: Real-time context drift detection - Impact: ContextGuard detects drift before it breaks production (96% precision)

*3. Bias Incidents* - Problem: Bias creeps into outputs, damaging brand reputation - Cost: Reputation damage, lost customers, legal risk - Solution: Real-time bias detection (<50ms, 12+ types) - Impact: BiasGuard catches bias before deployment

*4. Reliability Failures* - Problem: No way to validate AI responses before production - Cost: Production incidents, user trust loss, rework - Solution: 7-check validation system - Impact: TrustGuard validates reliability before deployment

*5. Limited Visibility* - Problem: No insight into AI system health - Cost: Reactive problem-solving, downtime, missed issues - Solution: System-wide monitoring and validation - Impact: HealthGuard provides comprehensive visibility

*The Reality:* Most teams face all 5 problems but only track 1-2 metrics. They're flying blind.

*The Solution:* We built AiGuardian to solve all 5 problems. 5 Guard services. Production-ready. <50ms response times. Single API integration.

*What are you seeing?* What hidden costs are you experiencing? What metrics are you tracking? Let's discuss.

No... not everyone is capable of doing hardware or software design... There are over 350 million people in the US. There are nowhere near that many software/hardware jobs.. or other IP generating jobs. Not only that, but corporations are bringing in a lot of people to do those jobs as well, driving down those wages.

It's not even just jobs, it's also the tax revenue itself.. the population is overburdened with taxes and increased prices combined with relatively lower wages due to excessive inflation the past few years. While tariffs can increase prices, they can also eat into the margins of foreign production leading to more insourcing of jobs.

Beyond those aspects is being able to handle production of critical infrastructure in times of supply constraints... such as war or a global pandemic. You can increase from 50% production of medications to 100% of domestic needs pretty easily, but scaling from 0% is almost impossible in any reasonable time frame.

There are plenty of reasons why having a chatbot partner is a bad idea (especially for young people), but here's just a few:

- The sycophantic and unchallenging behaviours of chatbots leaves a person unconditioned for human interactions. Real relationships have friction, from this we develop important interpersonal skills such as setting boundaries, settling disagreements, building compromise, standing up for oneself, understanding one another, and so on. These also have an effect on one's personal identity and self-value.

- Real relationships have the input from each participant, whereas chatbots are responding to the user's contribution only. The chatbot doesn't have its own life experiences and happenings to bring to the relationship, nor does it instigate autonomously, it's always some kind of structured reply to the user.

- The implication of being fully satisfied by a chatbot is that the person is seeking a partner who does not contribute to the relationship, but rather just an entity that only acts in response to them. It can also be an indication of some kind of problem that the individual needs to work through with why they don't want to seek genuine human connection.

>it's an unequivocally good thing.

the miracle that is humans and humanity came about through millennia of unrestrained fertility and lots of sex℠ producing many babies, most of whom didn't survive to adulthood. Insects and fish still do this on a grand scale. It's where we came from and who we are, and that's Not Bad™ and I think it's unequivocally a bad thing that we keep thinking we know better and interfering with it. we are failing miserably to propel our species forward for the future. "survival of the fittest" is a mistake, it's destruction of the no-longer-adequate that works the magic.

So you need 2% of your income to generate 100% of your income (assuming you need to get to work).

Sorry I just can't take these arguments in good faith. $100 in the richest city of country of the richest country in the world is basically nothing. If you can't allocate that towards your mobility then IDK what to say to you.

I can highly recommend Obsidian for long-term knowledge bases. Have been writing about using it well: https://bryanhogan.com/tags/obsidian

It's missing collaboration at the core, although it's possible to achieve this currnetly with third party solutions, or the next major update should also include it as it's the "multiplayer" update.

I read about this when I first discovered GrapheneOS, and it looked like it. And it may be partially correct.

But on the other hand, I have read a lot of "drama" between e.g. /e/OS and GrapheneOS, and more often than not, it looked like GrapheneOS was criticising actual limitations of /e/OS and /e/OS (a mix of the community and official comms) seemed to be the one being unfair.

GrapheneOS generally is pretty direct at saying stuff like "their approach is strictly less secure" or "they are often worse than Stock Android", and I understand that this is not good publicity for Murena. But I am yet to see one of these claims to be wrong: all I can say is that the tone is very direct and could offend the /e/OS people, even if the claims are true.

On the other hand, instead of just acknowledging and trying to explain why /e/OS may be a good choice (e.g. if you happen to own a phone that is not a Pixel and that is well supported by /e/OS), I have seen actually wrong claims from /e/OS against GrapheneOS (sometimes downright technically wrong about security/privacy). And while GrapheneOS is quite exemplary with their support (if your phone is supported, then it's best in class), I have run /e/OS on a couple of phones and I have seen by myself that some of the security updates were 3 years old while the Stock Android was actually up-to-date.

So yeah... I get that it's a sensitive topic, but I feel like there is more a long history of people accusing GrapheneOS of accusing people, and I'm not anymore convinced that this is actually true.

Yeah, "Le media" and "Mediapart" are "left wing" newspaper and not billionaire owned, there is right wing too, but they are smalls. Libé isn't owned by Kretinsky but Patrick Drahi, Kretinsky owns Mariane (right to far-right now...).

But anyway yeah, in France (and in other countries too ) there is a media oligarchy.

> Reductio ad absurdum doesn't really work when the subject is dog-whistles, by definition.

I was using a more globally recognizable example to illustrate it since you have already implied that you do not understand the Canadian context. It wasn't reductio ad absurdum, but just an example of the concept moved to a different domain.

> If someone says "we woke to a chaotic airport" and you go on about how "woke" is dog-whistle, I'd consider that to be an off-topic diversion, at best.

That's not what I'm doing literally or figuratively. I'm not picking on one specific word.

I am pointing out that specific phrases and ideas used to express a specific sentiment on a specific topic can have hidden meaning assigned to them by interested groups.

In this case the phrase is "... [booking.com's] free cancellation policy only really works in a high-trust society, which at least one prominent nation seems to be backsliding"

The ambiguous/suspect terms here are "high-trust society" and "prominent nation seems to be backsliding". I am not suggesting that we cannot use those terms without being suspected of anti-indian sentiment, I am suggesting that using that phrasing to convey a message on that specific topic is a pattern predominately invoked by those with anti-indian/immigrant sentiment.

Accusing anyone that uses the word "woke" of being necessarily political is reductio ad absurdum of its own sort, and I fully agree that using a single word once is an absurd way to determine political meaning. Fortunately that isn't what I said. At all.

I am leaving open that the OP truly does want to talk about changing social mores leading to businesses having to change their policies, and that this is not a comment on immigrant communities. But I am pointing out that they have used the same language and specific terminology that is used in anti-indian immigrant political discussions.

If their intent is not to target immigrants, fine, that can be clarified. If it is their intent, I would prefer that they plainly state that they think that immigrants are the cause of hypothetical future changes to policy at high-end luxury hotels.

Sorry for the late reply.

Collective bargaining would not apply to any of these salaries. Collective bargaining as we usually understand it sets the lower bound for salaries in a certain field, think of it as field specific minimum wage. Indeed, some Nordic countries have no minimum wage at all because ~all fields are covered by collective bargaining -- regardless whether the employees are part of the union or not!

So no, pay would not be lowered. I don't understand where this kind of a misconception comes from. Collective bargaining does not mean that everyone gets the same salary. As I said earlier, you are free to negotiate a higher salary, and companies wanting to attract top talent will still have to compete through compensation.

In the top engineering companies, collective bargaining could be used to negotiate other perks, like paid leaves, hour banks where you collect all work time exceeding a regular work day, paid parental leaves, and/or whatever topics are important for the work force. I'm not the one to define that though.

Collective salary bargaining is efficient in fields where the workforce is highly interchangeable, and the workers' ability to produce higher value is limited. If factory workers, miners, or nurses are not unionized they are really placing themselves in a precarious position.

Most of them weren't, but some were. If all you were doing was looking at screens of text, a long persistence phosphor could be desirable[0].

I've got one that is inside an Apple II monitor. Can confirm, the image looks very flicker-free, but has pretty bad ghosting if you're looking at anything that scrolls. It looks cool but is pretty rough to do any work on. The other green CRTs I have are barely more persistent than a regular black and white TV, and I've never heard of a long persistence color monitor.

its not that the USA can't produce semi-conductors. Its that semi-conductor production, at TSMC's scale (both in terms of number of units, yield rates, and depth) currently requires highly skilled workers to work a lot of their hours to "baby sit" the wafer production.

Maybe there is a world where TSMC can hire enough skilled workers and optimize processes enabling people to go home at 5p, but that is not currently the case.

For that sort of task: no, Tao isn't all that much better than a "regular researcher" at relatively easy work. But the tougher the problems you set them at, the more advantage Tao will have.

... But mathematics gets very specialized, and if it's a problem in a field the other guy is familiar with and Tao isn't, they'll outperform Tao unless it's a tough enough problem that Tao takes the time to learn a new field for it, in which case maybe he'll win after all through sheer brainpower.

Yes, Tao is very very smart, but it's not like he's 100x better at everything than every other mathematician.

>Hate to break your cherry, but that's all industries.

It's not binary where it either it is or it isn't but there's various levels to it and Pharma gets special privilege over industries like cars, phones or semiconductors, since it deals with people's lives.

> as Asian players in both China and India have largely disrupted the generics

Then why did I never took an Indian or Chinese made paracetamol, but all generics in my EU country I ever took from the pharmacy ware locally made? Meanwhile I can't buy a locally made laptop, smartphone, GPU, it's all Asian made goods.

Caelan Conrad made a few videos on specifically AI encouraging kids to socially isolate and commit suicide. In the videos he reads the final messages aloud for multiple cases, if this isn't your cup of tea there's also the court cases if you would prefer to read the chat logs. It's very harrowing stuff. I'm not trying to make any explicit point here as I haven't really processed this fully enough to have one, but I encourage anyone working in this space to hold this shit in their head at the very least.

I hadn’t heard of that until today. Wild, it seems some people report genuinely feeling deeply in love with the personas they’ve crafted for their chatbots. It seems like an incredibly precarious position to be in to have a deep relationship where you have to perpetually pay a 3rd party company to keep it going, and the company may destroy your “partner” or change their personality at a whim. Very “Black Mirror”.

Japan tends to be a favorite for most enterprise SaaS companies when opening an APJ sales foothold - no other Asian economy is of a similar size and open to Western firms.

Additionally, a Tokyo HQ often manages your South Korea and Taiwan operations as well because of legacy business ties from the colonial era as well as the flying geese era. That said, Sapporo does remain a bit of a niche area like Seattle or Portland before semiconductors because of how dominant Tokyo, Osaka, and Nagoya are.

Every time I see an article like this, it's always missing --- but is it any good, is it correct? They always show you the part that is impressive - "it walked the tricky tightrope of figuring out what might be an interesting topic and how to execute it with the data it had - one of the hardest things to teach."

Then it goes on, "After a couple of vague commands (“build it out more, make it better”) I got a 14 page paper." I hear..."I got 14 pages of words". But is it a good paper, that another PhD would think is good? Is it even coherent?

When I see the code these systems generate within a complex system, I think okay, well that's kinda close, but this is wrong and this is a security problem, etc etc. But because I'm not a PhD in these subjects, am I supposed to think, "Well of course the 14 pages on a topic I'm not an expert in are good"?

It just doesn't add up... Things I understand, it looks good at first, but isn't shippable. Things I don't understand must be great?

In Europe if an airline does that they have to pay you a penalty of a few hundred euro.

But KLM (Dutch flag carrier) found a way around that: if a flight is overloaded by weight they will keep all the passengers on board but leave their luggage behind. There is no direct penalty for late luggage, so many customers will get nothing except perhaps a little free shopping if they feel like filing forms to reimburse for having to buy clothes at their destination. But that's cheaper than the penalty for not taking the passenger on time, so KLM "optimized" it.

This feels like a dumb question, but why doesn't Cursor implement that tool?

I built my own simple coding agent six months ago, and I implemented str_replace_based_edit_tool (https://platform.claude.com/docs/en/agents-and-tools/tool-us...) for Claude to use; it wasn't hard to do.
