> All thanks to Trump's silly tariffs

The tariffs were just half of it, the attacks on national sovereignty were the other, and Pierre being his usual shallow and despicable self on the campaign trail were the third.

If Carney (or almost anyone but PP, really) were the head of the CPC, they'd have had a majority today. But looking at where the party's going, it's doubtful that the CPC will ever again elect a leader who can both read and write.

Of course what you are describing is possible, but those scenarios seem contrived to me. If you have reasonable designs I think they are unlikely to come up.

>Just because you aren't instantiating a template a particular way doesn't necessarily mean no one is instantiating a template a particular way.

What I meant is, if the thing is not instantiated then it is not used. Whoever does come up with a unique instantiation could find new bugs, but I don't see a way to avoid that. Likewise someone could just superficially meet the concept requirements to make it compile, and not actually implement the things they ought to. But that's not a problem with the language.

A systems-level look at why modern AI assistants often exhibit bureaucratic, high-latency behavior — not due to lack of intelligence, but due to layered safety architectures that overprocess ideas.

The post outlines a failure mode where safety checks, humility filters, disclaimers, and apology loops create a recursive overprocessing pattern, degrading information quality and slowing down reasoning.

This is not an argument against safety itself, but an analysis of how misaligned safety architecture can distort information flow and reduce expressive bandwidth.

Suppose I work in a construction company, and I'm holding a power drill, drilling some necessary hole in a wall. I am certainly performing some work as I push the drill into the wall, I apply a force in the depth direction, and a distance is traveled, the product amounting to mechanical work. But it is also true that electrons are flowing, causing (rotational) torque, and a certain angle is travelled resulting in mechanical work, applied by electrons, effectively miniature temp workers, sent out by the electric utility power company, effectively an (electron) temp agency.

I suppose most of the taxes should be paid by the electric utility, since it did most of the work. /s

> I found (it) not actionable

Tangental, but I found 'Have I Been Pwned' useless too because you can't enter your email and find leaked passwords associated with the address, instead you have to enter each password (and repeat for every password you want to check).

I know there's an explanation that the raw password is not being sent and instead being hashed locally and only part of the hash is sent. But I don't know how to verify that and it feels wild to type passwords into a random website. (if anyone knows how to verify HIBP does only what it says it does [rather than blindly trust and hope for the best], would love to read more about it)

a car cannot be used like a truck.

I think that’s more down to choice than possibility. I’ve hauled all those things home from the diy store in my boring Volvo with its roof rack. Had 600-odd pounds of sand in the back just last week.

4x8 plywood isn’t particularly heavy, and little consumer “150 pounds max” roof racks can hold a lot more than they claim.

I think "bad title" is not going to be the main concern people have with this kind of submission, compared to concerns that the content is of questionable value, and that any added-value of "let me ChatGPT that for you" is extra-questionable.

What, their CPUs will overheat? I've run infinite loops on cellphones lots of times without that happening. In fact, I'm running four of them right now, and have been for the last five minutes as I write this comment. The battery drain is annoying but I haven't seen instability. I've run plenty of compiles on cellphones (things like BLAS and Numpy) that take longer than that, and I've never seen one crash a phone.

I would expect that using the same certificate authorities for servers is probably not useful for client authentication, although maybe it might be if the only thing you care about is the domain name (although, it shouldn't be; anyways, many clients might not even have a domain name).

But, if you really need to use certificates from the CAs anyways, you might ignore some of the fields of the certificate.

Gardening/lawncare wouldn't work as well as you'd think - ride-on lawnmowers need fuel to run for extended periods, so they face the same charging problem (even though the client usually has a power outlet in their house, mere metres away). Ditto for a ton of pressurewashing equipment and such.

The problem is that we built our world around cheap portable energy, so problems that are trivial technically are difficult socially - the client won't let you use the power outlet, if they do they'll make you pay for the power use, asking is weird and unusual and requires more negotiating with the client, it's just not worth it. Like, if oil never existed then residential housing would probably be built with a special "contractor power outlet" that could be billed separately on a pay-per-use basis - call up the number, dial in your Designated Contractor Code or whatever fictional paperwork, and you get charged for the power you pull until the socket is unplugged.

Or maybe some other solution that I can't think of, because people in that world had to think of one and spent decades refining it. Or maybe they invented lithium batteries 90 years ago (~1935) and now they're on par with oil.

There is never a need to store a pin in the database, store it in temporary storage like redis. Set the TTL to the expiration date. You can hash if needed, but I’m less concerned that someone hacks into your reds instance and steals your pins from the last 10 minutes, bc everything else is gone.

There should never be a need to return a pin to the client. You’ve already texted/emailed it to them. They are going to send it back to you. You will check against your temporary storage, verify/reject, and delete it immediately after.

Agreed. I didn't score too badly (above 50% of native speakers and above 99% of non-native). Many of the words were obscure and extremely contextual. If you are in a particular field with a lot of jargon, you may know countless words, but I don't think it means anything.

Being able to correctly define useful words would be a better test of knowledge. Just because you “know” some words doesn't mean you really understand what they mean.

Bah, it's just a test for “book smart” people to feel good about themselves. One has to feel good about that time investment, I guess.

On a side note, I don't think using too many uncommon words is a good thing. It just obscures the meaning of what you are trying to say unnecessarily. But this is a status marker and a pretty effective way to create tribal boundaries; people love to feel smart without too much effort.

Je ne conçois non plus comment me parler en français devrait m'amadouer. Je ne me sens ni respecté ni bafoué par avance, quelque soit la langue dans laquelle on s'adresse à moi.

Qu'un touriste soit stupide, balourd ou suffisant, sa capacité à parler français ne lui sera d'aucun secours s'il souhaite échapper au jugement que je lui imprime.

Vous savez, j'essaie principalement de comprendre qu'est ce qui peut faire exister le cliché sus-mentionné "les français font exprès de ne pas parler votre langue". Quand je lis "Vous devriez parler français, nous apprécions cela comme une marque de respect" j'ai honte !

That’s fair. There are “recreational offroaders” in the sense of urban bros that do casual offroading on well-developed trails with associated infrastructure. That is the nerf version of offroading in the US. Some of those trails are cool on their own merits, I don’t want to take away from them.

The US has vast regions that casual tourists never venture into and have no infrastructure that are nonetheless economically important or excellent for exploring.

If you stay near the Interstates, you’ll be able to manage with electric vehicles. But the best parts of the Mountain West are pretty far from the Interstate Highways. The deep Utah, Nevada, or Arizona wilderness is phenomenal but you’d be an idiot to attempt that with an EV. Just getting caught in a mountain pass during a blizzard in May or September could be enough to cook you.

I’m not against EVs in any sense but the tech is still pretty risky for the realities of the Mountain West of the US. I have learned many lessons the hard way about how you can be stranded or die in the Mountain West that makes me cognizant of the limitations of EV currently.

I am bullish on EV, I’d love to have one if it met my technical specs, but they aren’t there yet.

Part of what's going on is that all of this stuff is developed by volunteers. If only one person, or three people or whatever, are actually willing to give up hundreds of thousands of hours of their own time to work on something, then those people get to make the decisions about what gets done. There's very little supervision from any kind of "upper management" to catch bad decisions.

On top of that, there's adverse selection here. Who gives up thousands of hours to work on some obscure corner of the Linux desktop? People with quite unusual thought processes.

The west is not quiet about Gaza by any measure. I live in the west and hear about it a lot. You practically can't escape reports. At this point I'd say it reflects your media diet if you aren't hearing about it.

In 2023 Azerbaijan ethnically cleansed Nagorno-Karabakh of ethnic Armenians[1]. IMO that is a better example of human rights violations that the west has been silent about. But that happened at the end of September 2023, and folks were more interested in talking about IP.

But my point is you will not hear about Uyghurs on TikTok, and that is a part of why a Chinese controlled media company should not be trusted. To say that you don't have to accept anything about the US or its media companies.

The parent attempted to excuse them by pointing out that the initial design was based on phone numbers. Putting aside the fact that initial design is irrelevant to present design criticism, they went out of their way to design usernames yet deliberately disallow signup without phone numbers.

> Not a very good case made since you obviously didn’t read the parent discussion.

This isn't an argument, do you have anything to back up your assertion?

Rust prevents the footgun, but also prevents shooting in the direction where your foot would be even if it isn't there.

There are absolutely places where that is required and in Rust those situations become voodoo to write.

C++ be default has more complexity but has the same complexity regardless of domain.

Rust by default has much less complexity, but in obscure situations outside of the beaten path the complexity dramatically ramps up far above C++.

This is not an argument for or against either language, it's a compromise on language design, you can choose to dislike the compromise but that doesn't mean it was the wrong one, it just means you don't like it.

A relatively simple but complex example, I want variable X to be loaded into a registerer in thos function and only written to memory at the end of the function.

That is complex in C/C++ but you can look at decompilation and attempt to coerce the compiler into that.

In rust everything is so abstracted I wouldn't know where to begin looking to coerce the compiler into generating that machine code and might just decide to implement it in ASM, which defeats the point of using a high level language.

Granted you might go the FFMPEG route ans just choose to do that regardless but rust makes it much harder.

You don't always need that level of control but when you do it seems absurdly complex.

It's expected for military operations to fly without transponder, they don't want to have their location visible. But it's crazy that they're also doing it in Curacao controlled airspace without agreeing a restricted area.

Even for training they set up restricted/military areas in airspace all the time. Not doing it here, in allied (Curacao is part of the kingdom of the Netherlands) airspace is unacceptable. They could have coordinated this in the normal ways so ATC would route civilian traffic around the military operations or talk to the military controllers (who can see both types of traffic) before sending an aircraft through the shared airspace.

This isn't new, it's how military operations are done all the time.

Any of the methods i mentioned is enough to get missile close, except may be microphones as limited speed of sound means that the plane would have moved significantly from the observed position, though again even that would have allowed to put missile into the vicinity and in general direction.

Watching Ukraine videos there is new game in town though - relatively cheap IR cameras. Using IR, day or night, you can detect a jet plane from very large distances and just guide missile to the plane computer-game-joystick style.

A recipe app I built primarily for me and my wife, but realized along the way that others might find it useful too. Tried to make the whole cooking experience as smooth at possible. The recipes are made for the app, and the app is made for the recipes. Tight integration which enables some really cool features. Currently working on algorithmic optimization of recipes based on how fast you work and how many things you can do in parallel. User configurable. This makes it possible to either do very beginner friendly one thing at a time, or speedrun recipes and do multiple tasks at the same time for more skilled people.

First launch will be in 2026 in Swedish. Later in 2026 English launch planned, and then based on demand other languages.

There are "bribes" and then there are "bribes as recognized by the law".

We all know bribes happen, but for the law to recognize a bribe as a bribe basically requires the two parties to have a signed and notorized legal document statating that they are knowingly entering into a quid pro quo, and that both parties are aware it's illegal to do so. Anything less than this, and it will never be prosecuted.

> 1. Do the other costs scale with the number of panels?

Mostly yes. Once you're at utility-scale, installation and maintainance should scale 1:1 with number of panels. Inverters and balancing systems should also scale 1:1, although you might be able to save a bit here if you're willing to "waste" power during peak insolation.

But think about it this way: If it was possible to reduce non-panel costs by a factor of 5 simply by building 5x larger solar plants, the operating companies would already be doing this. With non-panel costs around 65%, this would result in 65% * (1 - 1/5) = 52% savings and give them a huge advantage over the competition.

> 2. Vertically mounted bifacial PV […] 3. Battery […] costs are dropping

I agree that intra-day fluctuations will be solved by cheaper panels and cheaper batteries, especially once sodium-ion battery costs fall significantly. But I'm specifically talking about seasonal storage here.

> Also, please address the matter of using the overprovisioned power in summer.

I'm quite pessimistic about that. Chemical plants tend to be extremely capital-intensive and quickly become non-profitable if they're effectively idle during half of the year. Underground thermal storage would require huge infrastructure investments into distribution, since most places don't already have district heating.

Sorry, very busy today so I can't go into all details, but I still wanted to give you an answer.

Almost everything from a grocery store starts in, or ends up, in a water resistant package. There are a handful of exceptions like eggs in cardboard casing, but you can just wrap them in a baggy to solve that. For that matter, unless it's like an insanely torrential downpour, very little, if any, water is going to get through a closed bag.

If your observation is accurate, the more likely reason is that people just don't like going out when it's raining. Getting your shoes/pants wet sucks, getting your car (or truck) seats wet sucks, rain traffic sucks, there's more crashes - which suck, and by contrast you could just be sitting at home enjoying the relaxing sounds of rain, which doesn't suck.

It is not open source, it is not free. It’s a term tacked on to the MIT license.

It’s also vague as, what if I run a VPS provider and someone can upload images to a marketplace like thing, does that count as SaaS? How about if someone’s only use of my services is to run that image?

Studying at an university level is about building the skill to aquire new knowledge and methods yourself. Of course you will get guidance by the educators, but with too much guidance you're no longer learning the most essential lesson of them all.

As someone who teaches at an infliction point between theory and practise I can't stress enough how important it is that students go at issues themselves. You can have them understand all the theory, nod along, give the right answers when asked and then give them the real problem and they will look buzzled like they have never seen it. Because yes, they haven't.

That means studying and assuming they will hammer the knowledge into you is silly. You need to be the person that cares about understanding, like anybody who is good at what they are doing is, university level study or not.

The computer chips used for AI generate significantly more heat than the chips on the JWST. The JWST in total weighs 6.5 tons and uses a mere 2kw of power, which is the same as 3 H100 GPUs under load, each of which will weight what, 1kg?

So in terms of power density you're looking at about 3 orders of magnitude difference. Heating and cooling is going to be a significant part of the total weight.

Jokes aside, marriages don't fail because people assume roles in it, but because of stress, money, and lack of empathy and respect. I've literally met women who told me that if given the opportunity, they would not mind being housewives. Of course, this is not for everyone, but looking at what you were listing, and this is what it reminded me of.

Author here. I built this because I needed to run dimensionality reduction entirely in the browser (client-side) for an interactive tool. The standard options (UMAP, t-SNE) were either too heavy for JS/WASM or required a GPU backend to run at acceptable speeds for interactive use.

This approach ("Sine Landmark Reduction") uses linearised trilateration—similar to GPS positioning—against a synthetic "sine skeleton" of landmarks.

The main trade-offs:

It is O(N) and deterministic (solves Ax=b instead of iterative gradient descent).

It forces the topology onto a loop structure, so it is less accurate than UMAP for complex manifolds (like Swiss Rolls), but it guarantees a clean layout for user interfaces.

It can project ~9k points (50 dims) to 3D in about 2 seconds on a laptop CPU. Python implementation and math details are in the post. Happy to answer questions!
Ask HN: Am I having a mid life crisis?
by nsksk | 2025-12-16 07:25:14+00:00
I am 35 years old and feeling like I am having a midlife crisis. I grew up in a household where having a high paying job was seen as the ultimate goal of life, not having money meant you failed plain and simple. Only people that had something wrong with them didn’t have money, people that didn’t work hard or didn’t have discipline were the ones that didn’t have money and as punishment they had to work terrible jobs and live sad lives without opportunity. The only way out of this was to study HARD, and not just study anything but something that made good money. Something like engineering, medicine, becoming a lawyer, something society valued with money.

I was terrified of the life that apparently awaited me if I failed at my task of making money, so I feel like I just kind of panicked and chose engineering since I was interested in computers. Now after studying hard and getting a high paying job writing software, I can safely say I am completely unfulfilled.

I have just recently connected the dots that I just have been spending so much time in my life taking the safe path to make sure I could make money and I don’t even feel like I know myself well enough now to understand what I would actually want to do since that was never really a consideration point and more of a secondary benefit if you were lucky.

I don’t want to keep doing what I’m doing now as an engineer is all I know for sure, but I also don’t know where to go from here. I don’t feel like I have some hidden talent that I’ve just neglected my whole life but I also don’t feel like I tried or have had time to even find it if it exists and could make me feel more fulfilled in life.

What can I do about this? I’m ok with living a simpler life if it means I’m happier, I have come to the realization that I can live with failure more easily now than I can regret.
