cocoto··on Adoption of EVs tied to real-world reductions in air pollution: study
Way too expensive for most europeans countries and it’s after heavy subsidies from governments. Most people buy second-hand ICE cars and they will do it as long as they can be driven on roads. Stellantis cars are trash and in general the low-cost EV are trash for long travels.
cocoto··on European Alternatives
I think the biggest issue is that your product is not from a company generating money (and taxes). IMO as an european, I think we should aim for open source, not corporate software, but free and open source software is generating way less jobs and taxes money.
cocoto··on Ask HN: Do you have any evidence that agentic coding works?
From the very beginning everyone tells us “you are using the wrong model”. Fast forward a year, the free models become as good as last year premium models and the result is still bad but you still hear the same message “you are not using the last model”… I just stopped caring to try the new shiny model each month and simply reevaluate the state of the art once a year for my sanity. Or maybe my expectation is clearly too high for these tools.
cocoto··on Scaling long-running autonomous coding
If they are not programming then they could have more time to produce food themselves without using machines relying on energy (traditional vs industrial agriculture).
cocoto··on Scaling long-running autonomous coding
The complex thing is that you would need to take into account the energy used to feed the programmers, the energy used for their education or simply them growing up to the age they are working. For the LLMs it would have to take into account energy used for the GPU, the machine building the GPUs, datacenters, engineers maintaining it, their education etc etc. It’s so complex to really estimate these things from bottom up if you are not only looking locally, it feels impossible…
cocoto··on Understanding C++ Ownership System
Why are some examples full of errors? The `set_vec` method for instance does not bind the reference, you can't change the reference itself... so the code would simply copy the vector and there would be no dangling reference... And `B` is missing a constructor since the default constructor would be ill-formed (you can't default initialize a reference).

Anyway the article is quite approachable, do not take my criticism to shy away from writing!

cocoto··on Fix your robots.txt or your site disappears from Google
And what if your website is ad free and the AI full of advertising? At least the users get the information and the AI save on your bandwidth (in theory!).
cocoto··on Consent-O-Matic
I think most people don’t want to give consent to any of this so a simple block list is enough.
cocoto··on Consent-O-Matic
Simply enable the “cookie notices” list in ublock origin (available on every platform now, even iOS). According to the EU law if you don’t click accept it’s equivalent to denying.
cocoto··on OpenAI to test ads in ChatGPT as it burns through billions
What is the point for a company to pay OpenAI for products that it would recommend anyway? Companies are going to pay only if they can add bias to the results otherwise there is no point.
cocoto··on High-Level Is the Goal
I have yet to find a cross-platform UI framework that really feels native on Gnome. The reality is that there is no shortcut for native UI on all platforms, you have to use the “official” framework (e.g. GTK for Gnome). In my opinion the only softwares that should use a custom framework are professional grade apps where custom workflows can’t fit the native UI (e.g. Blender). Despite all the noise about native cross-platform frameworks, it’s absolutely not fooling anyone, we can spot this immediately on any platform.
cocoto··on Ask HN: How can we solve the loneliness epidemic?
Personally I’m living with a partner (only 50% of the time for now), have only two social activities per month outside work in average and some small talk at work. I don’t need more and have no intention to volunteer, join church or anything like that just for the social aspect. I guess the big problem is the (growing?) minority having close to no social experiences.
cocoto··on Every country should set 16 as the minimum age for social media accounts
Free speech violations in UK and the country pushing for more ID checks is a simple example.
cocoto··on Fabrice Bellard's TS Zip (2024)
You can use the number 0.{concatenation of all 1 bit strings ordered}{concatenation of all 2 bits strings ordered} = 0.0100011011…

Now an interesting problem would be to have the most “compact” number, where you can find all the strings of length n in a minimal number of digits of such number. It reminds me of the math problem solved by a 4chan user.

cocoto··on C++ std::move doesn't move anything: A deep dive into Value Categories
Personally I see std::move more like removing ownership because it’s not explicit from its call where the ownership is transferred.
cocoto··on I replaced Windows with Linux and everything's going great
Battery life is the best selling point of MacBooks and the reason these are selling like crazy. I’m a full time Linux user and I’m even considering buying a macbook and running a Linux VM full time because of the battery.
cocoto··on OLED, Not for Me
I also have one bought used. It’s the only way to have 4k and 200% scaling on Linux without everything being too big or too small. Size and ppi are perfect but sadly other aspects are becoming really dated (bad colors and contrast, high latency, low refresh rate etc).
cocoto··on “Erdos problem #728 was solved more or less autonomously by AI”
> One naive belief many people have is that proofs should be "intelligible" but it's increasingly clear this is not the case.

That’s one of the main reason why I did not pursue an academic math career. The pure joy of solving exam problems with elegant proofs is very hard to get on harder problems.

cocoto··on Anthropic blocks third-party use of Claude Code subscriptions
Not true, most tools are deterministic. For instance my programming language LSP just works 100% of the time with no failure. It doesn’t hallucinate any types, methods or variables.
cocoto··on Show HN: DoNotNotify – Log and intelligently block notifications on Android
I’m now an iOS user but the problem is actually the same here : apps not respecting communication channels to push ads (mostly to their own app or service). I usually fully block notifications from most apps but for some apps the notifications are really convenient (carpooling, transport or delivery app). Yes I want to know if the train I booked is delayed. No I don’t want to be notified that you are now partnering with another transport company and that you are sharing 5% off coupons to try it… I systematically give a 1 star review explaining the issue and mail the devs if possible. I even think that Apple Store and Play Store ToSs are against this practice but they are not enforcing it sadly…
cocoto··on An off-grid, flat-packable washing machine
Sadly arm strength and endurance is way worse than legs, this should obviously work with pedals like a bicycle. I would even be ready to buy one to replace my daily commute when working from home.
cocoto··on EFF launches Age Verification Hub
Such sites would be illegal if not sharing the header back from the source website and be banned as much as adult websites incorrectly setting this header. It’s not a real problem.
cocoto··on Fighting the age-gated internet
> Kids can access the internet in all kinds of places outside the home, and outside the purview of their parents supervision. Schools, libraries, friend's houses, public wifi anywhere.

Then these places should make sure kids are not doing wrong things on the web on their machines. Just like a shop should make sure to not sell alcohol to kids. A library should have some kind of web filter anyway to at least block porn.

cocoto··on VLC's Jean-Baptiste Kempf Receives the European SFS Award 2025
The award is well deserved, VLC was a godsend a few years ago but I’m not sure what VLC brings to the table nowadays. All other players play videos just fine on Linux now. I guess VLC is only a thing on Windows because the default software is crap. On Linux almost everyone now use whatever is the default player or MPV for the nerds.
cocoto··on No science, no startups: The innovation engine we're switching off
If for instance higher ups from all companies require you to hire only whites with straight blond hair, a certain weight/size and with green eyes, you will quickly need to hire the bottom of the barrel of this group to expand your teams.
cocoto··on `std::flip`
I love Haskell but when writing C++ I always avoid functional style gibberish. I feel like this style of programming only works in languages properly designed for that.
cocoto··on US cities pay too much for buses
Completely false, buses are way louder than multiple cars. Buses make tons of noise when accelerating and many have obnoxious added sounds at stops for security reasons. As a full cyclist I would gladly prefer no bus and more cars. Moreover the bus are more dangerous for cyclists and pedestrians.
cocoto··on Solving a wooden puzzle using Haskell
Edit: Under 10s with CP-SAT after removing many variables (had multiple variables for the same pieces).
cocoto··on Solving a wooden puzzle using Haskell
I tried modeling the problem as a mixed-integer linear program (one binary variable for each possible piece position) and CP-SAT solved this one in two minutes.
cocoto··on Betty Crocker broke recipes by shrinking boxes
Box cakes are widely available in most of Europe. They taste more than ok but sure nobody here would claim it’s a family recipe.
