  • In a world where this fake shit didn’t take hold we could have had real wireless charging by now, if you think the “wireless” charging is good now, just think what true wireless would be like. You could walk into a room and your phone just starts charging with 0 effort. None.

    You know this is possible how exactly? Wireless power distribution has been considered since Tesla’s time. Yet it still hasn’t been done outside of laboratory environments or very short distances. It’s definitely possible, but making it practical might not even be possible within physics as we currently understand it.

    For example a very power light beam like for example a laser beam can transfer a lot of power over some distance. It would also cook you, burn you, or make you go blind. It would also require precise alignment between transmitter and receiver, as well as very expensive transmission equipment.


  • Feathers are the things birds have that are part of their wing and help them fly. Pens were made from feathers at sorme points in history. I think the term you are looking for is nib, if you mean the metal part of a pen that touches the paper.

    You have pens like the platinum Preppy and platinum plasir which have double seals around the nib. I left my preppy for an entire year and it still didn’t dry out. They aren’t the only brand to use tricks like this, my TWSBI Eco was also left for a year and was a-okay. It’s always good before buying a pen to check the reviews and see what their cap seals are like. Rollerballs do require less maintenance though you are correct. If you do leave a fountain pen and it gets clogged there are ways to fix it, as I had to do with two more of my pens that did clog when they were left with the others.

    I’ve used cheap mechanical pencils before but not expensive ones. How much better are more expensive mechanical pencils?


  • Maybe I haven’t explained this but with regards things like handwriting and special education my country isn’t that well put together. They hand kids ballpoint pens for the most part unless you are in private school. Some schools force kids to use pencil even.

    Cursive is fundamentally less legible and harder work for most students to learn. It should be taught yes, but not as the only way. Schools often force people to use cursive even when that person doesn’t have that skill, and the school isn’t willing to give them proper lessons on it or the lessons they give aren’t of good quality. It was a whole thing in my primary school.

    I have actual clinical issues in several different areas of development, not just coordination. You can’t remove all issues before primary school starts, I am entitled to some help even now as a 23 year old PhD student and still have issues. I wouldn’t even have been accepted into primary school if my parents hadn’t gone out of their way to get me tested by psychologists as I had issues the school weren’t willing to get me tested for that were picked up on in preschool.

    I can write pretty well now including cursive. It’s not clear to me how much of the problems I had were because I was younger and at a lesser stage of brain development or how much was bad teaching. Maybe if you know more developmental psychology than I do you could answer that question, but I suspect that answer will be different on a case by case basis.


  • I too think ball point pens are horrible. Fountain pens are not that expensive, last a lot longer as they are refillable, and just write better. There are some rather bad fountain pens out there though lol. Platinum Preppy is pretty much the gold standard for cheap pens under £10 or $10. Platinum plasir is a little more expensive but has a more durable body and cap made of metal using the same nib and feed as the preppy. You can also get disposable fountain pens now that aren’t half bad.

    Liquid ink roller balls are a good product too and are a nice middle ground between ball point and fountain pen. Although to be fair I wouldn’t be against a return to good old fashioned dip pens as these are the best for calligraphy and honestly look cool as heck in my opinion.


  • Forcing children to do cursive was not really the point I am trying to make. Yes it’s technically more efficient to write that way, but it’s also considerably more complicated. Forcing children with disabilities to do it leads to all kinds of problems, and makes their writing less legible. I am more talking about techniques that avoid issues like RSI. If we are making children do things we should be teaching them the correct way to do it, not half assing it. While I think we should still teach cursive, I don’t think it should be mandatory. In fact I actually want to see more keyboard use with proper ten finger technique, as that is useful for the real world. Typing technique is also something schools love to neglect. It’s also better to give kids that option as even with better handwriting instruction some just do not have the required motor skills through no fault of their own. People like me were forced to do handwriting practice despite having significant coordination issues, and never being taught the right technique. Eventually I had to dig through obscure corners of the Internet to find out the right way. Situations like that should never be allowed to continue for as long as it did in my case. Either by actually teaching the right technique in the first place, or in cases where that doesn’t work by switching to typing instead.


  • Key chording has always been faster than conventional single letter typing, and that tech has been around for a long time now in the form of stenography machines. Yet most people learn on a conventional keyboard because it’s simpler and more ubiquitous. This is true even now that chording has been adapted to programming and similar tasks.

    You have to remember we live in a world where most people don’t even know how to write properly, even those who do it as part of their job like doctors. If you draw letters by moving your fingers, you’re doing it wrong by the way. The actual proper technique involves using your shoulder, elbow, and wrist to do most of the work. We’ve known about this for centuries, and these techniques were designed with dip pens, quils, brush, and fountain pens in mind. The cheap ballpoint pen along with rather bad instructions from teachers has led to proper handwriting technique being forgotten, and causes problems like RSI in people who handwrite regularly.




  • The difference here is that the ISP is up charging for multiple devices, meaning this isn’t all being done for benevolent reasons.

    The way many apartments work for non-students is each has its own WiFi. Honestly compared to how bad some Hall’s WiFi is this is a better option, but it’s not without problems. A lot of ISP routers either don’t support or don’t turn on by default DFS channels, 5.8GHz channels, 6 GHz band, or have WiFi 6 for BSS colouring. This means there will be loads of interference between adjacent WiFi networks.

    It’s really frustrating especially when you have ISPs like Virgin whose kit has DFS support, but despite touting smart wifi they just never enable it, and most people don’t know to enable it either.




  • The rust guys would have gained a lot more traction by just asking the C guys to keep a bunch of comments up to date detailing the semantics and error checking procedures, and promising to edit their rust API if the C code changes, but I suspect they didn’t ask for that because they know that no guarantees come from a comment and they want to be sure that the rust code works across all the possible scenarios and in rust culture, that is always documented in the type system where it can be enforced.

    I could be being daft but I thought this is more or less what the Rust guys were asking for. Tell us the current symantics of the system, and if it changes in future let us know what the new semantics are and we will fix the Rust code accordingly.

    I do understand what you mean though about enforcing restrictions on what the C guys can do without breaking the Rust code. I think you run into situations wherever two languages meet. The way most projects handle this is the upstream releases a new version, or a release candidate of a new version with their breaking changes documented and then downstream updates their stuff accordingly when they get time. Obviously this is one project, but I imagine it’s possible for the C guys to update stuff in a pull request and then drop an email in LKML to the Rust guys so they know stuff needs fixing. None of this seems that hard to me.

    Ultimately though everything here is Linus decision. Either your in or your out. If Linus says yes to Rust doing whatever then that’s what’s going to happen. Likewise if he says no, then it’s not going to happen that way. Until he weighs in no one can really say how this will end.

    Personally though I disagree with the C guys. Safety features are important and should be used where it is practical to do so. Until now C has had the justification that it’s still the fastest language and by a significant margin. Now a somewhat safe language like Rust exists with the same speed and capabilities I don’t think we can afford to continue ignoring safety for the sake of a few bruised egos. If this was a proper industry like aviation safety would always come first, and if that means adopting new technologies and forcing people to adapt. I can understand if C devs have a hard time adapting, I don’t expect it to happen overnight. The expectation though should be they should learn some Rust eventually, even if it’s just enough to know the type signatures and what not that they might break with their changes to C code. Kernel devs are supposed to be some of the smartest computer people out there. If they can’t learn even that small amount of another language then should they really still be kernel developers?

    This is false. Anyone who has used these tools for long enough can tell you this is false.

    LLMs have been used to write computer code, craft malware, and even semi-independently hack systems with the support of other pieces of software. They can even grade student’s work and give feedback, but it’s unclear how accurate this will be. As someone who actually researches the use of both LLMs and other forms of AI you are severely underestimating their current capabilities, never mind what they can do in the future.

    I also don’t know where you came to the conclusion that hardware performance is always an issue, given that LLM model size varies immensely as does the performance requirements. There are LLMs that can run and run well on an average laptop or even smartphone. It honestly makes me think you have never heard of LLaMa models inc. TinyLLaMa or similar projects.

    Future LLMs will still only have this capability, but since their models will have been trained on LLM generated garbage their results will quickly diverge from anything even remotely intelligible.

    You can filter data you get from the internet to websites archived before LLMs were even invented as a concept. This is trivial to do for some data sets as well. Some data sets used for this training have already been created without LLM output (think about how the first LLM was trained).

    LLMs have legitimate uses today even if they are currently somewhat limited. In the future they will have more legitimate and illegitimate uses. The capabilities of current LLMs are often oversold though, which leads to a lot of this resentment.

    Edit: also LLMs very much are AI (specifically ANI) and ML. It’s literally a form of deep learning. It’s not AGI, but nobody with half a brain ever claimed it was.



  • They aren’t asking C devs to write Rust code, which is what the guy being a heckler was claiming. Why don’t they want to right Rust? For exactly the reasons you describe. The thing is though that’s not currently being asked of them, all they actually want is the documentation to create that code themselves.

    You really don’t have to explain any of the culture clash to me lol. I’ve written both C/C++ and Rust. My C and C++ coding skills are demonstrably better (or at least used to be, it’s been a while) than my Rust skills. Why? Because of how complex those guardrails are. The difference is I have the self awareness to know that my lack of Rust skills doesn’t mean that the language is bad, or that C is a safe language to use. Rust tutorials could be improved. Perhaps an easier to use language like Zig might be more useful for some people. I feel like it’s a good compromise between safety and ease of use. Rust though is still incredibly progressive for the industry, and will improve systems security, maintainability and reliability going forward if only people would stop getting in the way.

    AI at this stage is just a tool. This might change one day, but today is not that day. Blame the user, not the tool.

    AI and ML was being used to assist in scientific research long before ChatGPT or StableDiffusion hit the mainstream news cycle. AIs can be used to predict all sorts of outcomes, including ones relevant to climate, weather, even medical treatment. The University I work for even have a funded PhD program looking at using AI algorithms to detect cancer better, I found out because one of my friends is applying for it.

    The research I am doing with AI is not quite as important as that, but it could shape the future of both cyber security and education, as I am looking at using for teaching cyber security students about ethical hacking and security. Do people also use LLMs to hack businesses or government organisations and cause mayhem? Quite probably, and they definitely will in the future. That doesn’t mean that the tool itself is bad, just that some people will inevitably abuse it.

    Not all of this stuff is run by private businesses either. A lot of work is done by open source devs working on improving publicly available AI and ML models in their spare time. Likewise some of this stuff is publicly funded through universities like mine. There are people way better than me out there using AIs for all sorts of good things including stopping hackers, curing patients, teaching the next generation, or monitoring climate change. Some of them have been doing it for years.
