0xEF··on The Arduino Uno Q is a weird hybrid SBC
It's not exactly a big problem, but my company makes a three-axis desktop CNC machine powered by an ATMega328P that is dependent on having a Windows PC connected to it in order to run the proprietary software. Uno Q has me thinking we can eliminate the PC along with our custom PCB, making a more compact and convenient stand-alone system that would also come with a lower price tag. I may order a few to experiment with this idea, but again, it's not a huge problem and something only specific customers would care about.

I'm curious what the Maker community comes up with, provided it sticks around and remains supported, unlike the Edison.

0xEF··on 10M people watched a YouTuber shim a lock; the lock company sued him – bad idea
Othering is easier than improving. An old philosophy professor taught me that at a community college when we started getting on the subject of philosophy in politics. This was probably 20-something years ago, now, but one of the many things that stuck with me from his teaching, and makes even more sense now than it did then.
0xEF··on My favorite cult sci-fi and fantasy books you may not have heard of before
Weir gets a lot of praise because his writing is accessible. While I also demand a bit more from the sci-fi I enjoy in terms of their narratives providing thought-provoking moments and a certain depth of information that we tend to call "hard" sci-fi, I'm not about to take a dump on Weir's work. He knows what he can do and who his audience is, so he writes for them. That is, arguably, the smartest thing any author can do if they want to make a living at it.

I had the same vitriol you do for Weir toward Ernest Klein. Absolute shit author in my opinion...but my opinion doesn't matter. His first book was still a wild success with a movie adaptation despite having one of the weakest plots and and some of the flattest characters I have ever seen in print, dressed up in a patchwork coat of nostalgia, which is the only reason it had the mass appeal that it did. But the book was not written for me, was it?

I think we forget, sometimes, that authors don't really owe us anything, that they're trying to pay the bills doing what they do, so our approval means little and only makes us look like self-rightious jerks so I had to learn to let that go and just not read those books that weren't jiving with my tastes or demands. In the end, let people have their books they like because, well, at least they're still reading and not watching TikTok or whatever.

0xEF··on My favorite cult sci-fi and fantasy books you may not have heard of before
What's aspects of sci-fi or fantasy draw you? I personally go for the weirder sci-fi that seemed to come out of the imaginative (and, well, drug-fueled, probably) 60's and 70's, so my recommendations tend to come from that.

Dune by Frank Herbert - I'll get the obvious one out of the way. Everyone needs to read at least the first book. The world-building is a commentary on our own and none of the movies, series or games will every really capture the books in their entirety. There is just so much more to Dune than the barely-below-the-surface treatments we get with film because they have to appeal to a mass audience that tends to have the relative intelligence of my left shoe.

Candy Man by Vincent King - take PKD's Electric Sheep question of what makes a human a human, then explore the answer in a far-flung future that ends up being a bit of a nightmare circus. Great world-building, here, but King reveals in slow morsels that leave us with questions and fuel turning the page. While his other works are not really that prolific, he hit the nail on the head with this one, bringing some dialect playfulness to the writing that just adds to the immersion. It's a haunting world, unsure of why it exists due to short memories and withholding of information, and unintentionally hints at the modern day disquiet of man as we race toward whatever Singularity we have accidentally or intentionally created.

Colossus by D. F. Jones - a bit like Wargames but more swanky, the US and Russia each create artificial super-intelligence then let them talk to each other, which goes about as well as you can imagine. The story hints at the notion that as soon as politics gets involved with science, things tend to get really cocked up, resulting in hostile takeovers, or worse, annihilation. It's a short read, and should be on the to-do list of anyone experiencing existential dread over the AI race today.

A Canticle For Leibowitz by Walter M. Miller - everyone needs a bit of post-apocalypsia now and then and I always recommend this one to get your fix. Here's an extreme treatment of what happens when anti-intellectualism becomes the modus operendi as we are thrust into a harsh and desolate world brought about by global nuclear war, roaming mobs blaming science (rather that politics, as Simpletons will do) for getting humanity into the mess it's in, going so far as to forbid pretty much any book-learning or education beyond the church. As artifacts from the past (our present, more or less) are uncovered, things get a bit hectic.

I'm also happy to take any recommendations, enjoying other authors like Stanislaw Lem, John Brunner, Robert Heinlein, Vonnegut, Jack Vance, etc. Reading books is probably one of the few things in my life that makes me feel a little less alone.

0xEF··on Ask HN: What's your favorite non-tech/not-quite-tech blog?
Thanks for these two! Receipt is right up my alley, being a lover of bookstores in general.
0xEF··on Erowid - Documenting the Complex Relationship Between Humans and Psychoactives
Likely. I spent a lot of my youth exploring the idea that the brain is sort of like a radio that could be tuned to different layers of reality using psychoactives. Also had a bit of a love affair with DMT for awhile, as well as trying to find the right combo of “soft” drugs that would induce hypnogogic dream states.

As fruity as all that sounds, I learned a lot about chemistry and how to conduct (or not conduct, perhaps), verifiable research, which is an important part of my thinking today as we navigate an ever-increasing flood of claims about tech, medicine and mental health. I have to imagine HN attracts some pretty analytical minds by default, my own being novice, at best.

I have a lot of great respect for the folks at erowid and I’m glad to see they’re still around.

0xEF··on 60k kids have avoided peanut allergies due to 2015 advice, study finds
I’d argue that the fear you speak of spread because it was profitable. I hit the 90’s in my mid-teens and boy howdy did it seem like every news outlet, especially the local ones, had their sites set on making us terrified to eat or drink things we previously consumed without much thought. Fear gets viewers, which is how revenue is generated, so there’s an arguable conflict of interest there.

The real problem is some of those claims and reports were true, but we were so inundated with the rhetoric that everything was going to kill us that many of us sort of lapsed into apathy about it. Stepping back, the food industry in the US clearly does not have consumer health at heart and we struggle to find healthy options that avoid heavy processing or synthetic fillers. Those parents who sheltered their babies back then may have been on to something when it came to stuff we consume and we should have been on the path to demand better from our food sources had more of us been more diligent with our grocery choices (myself included, at the time), but instead we ended up with bread that lasts unnaturally long and has an allowable amount of sawdust as an ingredient.

0xEF··on Space Elevator
Are we to assume they would be falling straight down? Because I'm pretty sure that's wrong. I'm not a physicist, though, and am happy to be corrected because every time the Space Elevator comes up, I want to know what happens when catastrophic failure occurs and how we'd mitigate that.
0xEF··on Space Elevator
It's my understanding that the Karman Line the conventionally accepted "edge" where you leave the atmosphere and enter outer space, but many call this out as a fairly arbitrary point, arguing that there is no measurable boundary. Useful as a point of reference for positioning, though. Neal possibly just used it as a marker but chose to not define it for this reason.
0xEF··on How I bypassed Amazon's Kindle web DRM
Not that I agree with it, but I do see the logic. The word "munitions" can be replaced with "materials," since it literally refers to materials used for warfare. That isn't necessarily limited to things that shoot or explode. It's a brilliant bit of pedantry if you step back and think about it.
0xEF··on Ask HN: Why is it so hard to design an open-source smartphone?
That's the one, thank you!
0xEF··on Ask HN: Why is it so hard to design an open-source smartphone?
> It's about who is in control.

Nail on the head. So long as the consumer does not have any power, we can be herded like cattle to wherever the devices we now depend on want us to go.

As an aside, perhaps you can help me remember the name of project? I think about a decade ago, now, someone was working on a completely modular smartphone. The idea behind it was that you purchased the base "frame" with the screen and rudimentary functionality, but then purchased modules based on your needs, to add things like wifi capability, cameras, speakers, etc. Perhaps more importantly, these all snapped into the back of the frame, which made them easy for even the casual user to install/uninstall functionality at-will.

Do you (or anyone reading) remember the name of that project?

0xEF··on What Does George Orwell's '1984' Mean in 2024?
> I take the view that government already knows full well who I am especially given that it once employed me to do surveillance work.

I have to imagine you have some stories or lessons worth sharing, for sure.

There was a point where I said the same thing; I didn't really care if the government knew my activities and whatnot because I was not hiding anything, and well, part of participating as a tax-payer in a functioning society involves records and information. That I get.

However, regardless of where you or anyone reading this stands on the political spectrum, particularly in the US, you'd have to admit that there's some trepidation regarding that massive amount of information about each of us that is out there and how it can be used against you, even if you have done nothing wrong. To use a pointed example, I would rather not be labeled and treated as a dissenter because I played Dungeons & Dragons online with a person who identifies as queer or trans, even if I may or may not have been completely unaware of that fact. That's just one such extreme example, but it does not seem so extreme anymore, and with each passing week, it seems like using information against people in that exact way is getting more and more normalized.

My biggest fear about the US and Big Tech collaboratively heading in that direction is being actively realized, and that is ultimately what had caused me to...not "give up," but more akin to "stop fighting." Don't have the energy anymore, barely enough to sweep up some of my own footprints, let alone those of people I care about that DO have that social media addiction you and I lack.

Appreciate the discussion and your perspective, given that it is a little more "insider" than most. I wish I had more to add, but I can see my cynicism creeping back into my replies.

note: since my example is a hot-button, I want to ensure that I am clear about my own stance, here. I do not care how anyone identifies, that's up to them and not for me to decide for them. All I care about is whether or not they're a good person, treating others with the same kindness, respect and support that they would like to receive. Bottom line.

0xEF··on What Does George Orwell's '1984' Mean in 2024?
The thing is, for the surveillance state to be completely obliterated, what the previous commenter said is only a sliver of what has to happen. Yes, consumers would have to put all their devices in the trash, disconnect everything from the Internet and never use it again, etc, but also start tearing out telephone poles, police vehicles, anything with a camera or microphone, etc. That is daunting, so it's understandable why so many either just give up the fight or satisfy themselves with some limp-wristed attempt like just running an ad blocker or VPN or something and calling it good.

The diligence required to stay either low or off (if you are lucky) the radar, as it were, is so exhausting as to be impossible for the common tech consumer. I tried it, for a long time and it came to be known as a War of Attrition in my head because it is one that I no longer believe we can win, having passed the point of no return by trading our privacy for safety and convenience over the course of three decades; a victory by inches for the tech companies, to be sure.

The funny part is, my problem was never with hackers, so the way the rhetoric spewed over the years claimed that this is all for my own safety never clicked with me. "Your data is safe with us!" Okay, who are you, who are you connected to or funded by and what cause do I have to trust you? I learned at a pretty young age that if someone is telling you "this is for your own good" they're the ones exploiting you. So now we have copious amounts of categorized data in the hands of entities that not only make massive profit from it, but will (if they have not already) turn it over to the increasingly conservative world governments who enjoy making lists of people they don't like.

And we all know where that leads.

0xEF··on New Alzheimer's Treatment Clears Plaques from Brains of Mice Within Hours
That's fair, I guess, but say there were some way for me to sign a contract saying they could test on me should I become afflicted Alzheimer's? Wouldn't there be some sort of legal protection for them, then?

Because I'd happily do it. I've watched multiple family members suffer from some form of severe mental decline and it is horrifying enough to make me willing to sacrifice myself if there is even a sliver of a chance that my sacrifice will help future generations avoid that pain. And since we're all nerds here, we all know that if we want to know if a thing actually works the way we want it to, we have to test it repeatedly in its working environment.

0xEF··on Show HN: Firm, a text-based work management system
I don't disagree with you at all, but my biggest hangup with GUI-based software is twofold:

1. It tends to be bloated, with developers slapping framework upon framework, creating a mess of background wiring that is prone to a dictionary's worth of issues that will either frustrate the user or confound the person maintaining it.

2. UX Designers approach their jobs incorrectly; they assume they are smarter than the user. Interestingly, this might actually be true on paper in most cases, but the practical reality is that the user needs to do things the user's way, not the way the the developer wants them to.

If we could find ways to smooth those two glaring issues, I posit that we'd see a lot of problems with productivity and workflow melt away. Caveat; I'm not a software developer, so I'm sure anyone who is thinks I'm speaking out of school right now. Fact is, I've worked in a few different industries over 40 years, and one of the biggest thorns always seems to boil down to the software not being quite right for the team/application, so workarounds have to be invented, adding layers of complexity on what is already a decidedly fragile system.

0xEF··on Show HN: Firm, a text-based work management system
This is interesting, very similar to a project I am working on, which is a cli asset manager for a small repair shop. Basically, mine keeps track of service tickets, customers and inventory while being query-able to help identify trends in problem products or recall records for warranty disputes, etc. It's just a silly little project I started in my spare time because I got fed up with having to open up three pieces of software with clunky UIs and frequent crashes to accomplish what should be fairly simple and straight-forward tracking and analysis. My biggest hurdle was getting it to export to a nice looking PDF that could be emailed or printed later.

While mine is functional, yours looks A LOT more refined, so I think I will play around with it and see if I can't adapt it to my needs.

I try to work in the terminal as much as I can since that's where I'm most comfortable, but when it comes to business software like CRMs, HRMs or ERPs, especially geared toward smaller shops, the selection for terminal-based options is severely lacking.

0xEF··on What Americans die from vs. what the news reports on
I don't know for certain, but I believe it's because newpapers (aka "The Press") are at risk of libel or slander charges if they don't get their facts straight. That may also be a US-centric thing, too, I am not sure. To put a pin on it, we want to believe that the possibility of punishment for misrepresenting facts imposes some level of accountability on a print publication.

Still, despite the fact that they can be sued for lying by the people they are lying about, I'm sure they find plenty of ways to bend the truth while still technically telling it.

I suppose that calls into question why we trust any media source that we can't directly verify ourselves as an authority. It's all very confusing to me, to be honest and I simply don't know what to do about it. Not being able to trust information is maddening.

0xEF··on Ask HN: What are you working on? (October 2025)
I'm pretty interested in following the progress of your MUD server, if you have any way for me to do that. I was a heavy player back the day, mostly Circle/Diku MUDs, and still try one out from time to time.

Lately, I have been considering creating my own as a "something to do in my downtime" project, using Coffee or Evennia, but if you're creating a full server environment that makes rolling out a playable world more convenient, sign me up.

0xEF··on (Re)Introducing the Pebble Appstore
I'm not the person you asked, but on my OG Pebble, I get about 2 full days of battery on a full charge. However, that's down from about 4 or 5 that I recall from early adoption of the device.

The battery is clearly unhealthy, but hanging on. When I charge my old Pebble, after about 15 minutes or so, it claims to be fully charged. It isn't. If I take it off the charge after only 15 minutes, it will show a full charge, but deplete rapidly, usually within about 20 hours. If I leave it on the charge for a few hours, then use it, I get 2 solid days or sometimes a bit more than that.

My OG model is also one of the originals that does _not_ have the fours screws in the back, making it impossible to change the battery should it finally fail. A few years back, I picked up some original Pebbles on eBay for cheapr since the batteries would no longer hold a charge on those, all models that did not have the four screws on the back, just to see if I could find a way to open them clean. Every attempt I made failed, damaging the display and housing.

If you want to try an old Pebble, find one of the ones with the screws on the back panel and you can buy fresh batteries that will fit. Or get an old Pebble Time/Steel model, which are easier to maintain. I see them go on eBay for between $30 - $50 USD and maybe like $10 USD for a new battery. That's nothing for a basics smartwatch with a cool history.

0xEF··on Daniel Kahneman opted for assisted suicide in Switzerland
You're not missing anything. I did not want to get too deep into it here, because let's be honest; thinking about having to take our own life is a really, really dark place to go, even if it with the best of intentions. I'm not really sure that HN is the place for that type of discussion, at least not on any detailed level.

At the moment, I have standing orders in place that no heroic measures or treatments should be enacted in the event that I am in a terminal or vegitative state. I've communicated clearly to family members that would be responsible for my decision making that things are not to be prolonged or dragged out for the sake of emotional contrivance.

Without knowing how we will die, it's really quite impossible to plan around it, of course. My comment, more or less, expresses my desire to have more control over my exit in the event that I am put in a position to become a massive burden on those I love; this is something I consider a reasonable and rational request, where the folks that make our laws do not. None of that changes without discussing and sharing our viewpoints on the matter, though, which I suppose was all that I was doing.

0xEF··on (Re)Introducing the Pebble Appstore
Old Pebble watches are still very useful due to the Rebble community. I am still rocking my OG Pebble to this day because of them, so they get all the kudos, here.

In fact, because my old one still works for my needs, it's making it difficult for me to invest in a new Pebble, despite wanting to support the project. Part of that is the idea of upgrading for the sake of upgrading directly opposes my ethos of keeping as many electronic devices out of landfills as possible, but part of that is also straight up nostalgia that I get to experience every day when I use what essentially amounted to the perfect watch for me.

0xEF··on Daniel Kahneman opted for assisted suicide in Switzerland
I think the suggestion needs more thought, but I don't necessarily disagree with the idea of making my exit before the dementia really sets in. I've directly cared for two family members who suffered from it (collective 5 years of my life, which I'd like to think gives me a pretty good view of what the disease can actually do to people) and I decided for myself that I'd rather be quietly killed than put my loved ones through what I went through as a caretaker. While also trying to work a full-time job and maintain my own sanity while I watched people I'd known all my life be destroyed, becoming tortured versions of themselves like something out of a body-snatchers horror film.

We, the loved ones, made the decisions to keep them going and I wonder how fair that was to them. We tend to not want to let people go, choosing to sacrifice quality of life for the sufferer and those around them for, what, a few fleeting moments of possible clarity? The opportunity to say goodbye to someone who may or may not even understand what is happening?

The events I went through with my family hurt us in ways that will not likely ever heal, despite effort on at least a few of our part, and it did leave me wondering if I would put my son or wife through that should something similar ever happen to me. I decided against it, seeing as I am at the age where these are very real possibilities. In the US, we have DNRs ("do not resuscitate") and living wills that offer prior directives, but something like assisted suicide is not allowed here unless some very extreme circumstances are met, because insurance companies and hospitals make more money from suffering people than dead ones. I'm a strong advocate of the right to die, but it is a decision that needs to be made some extensive consideration and documentation before one actually needs it.

0xEF··on Daniel Kahneman opted for assisted suicide in Switzerland
Having a living will is a great idea in general. My dad got a brain tumor and had no documentation on what he wanted do with his estate, in the event he became vegetative, etc. By the time he realized he needed one, it was too late for "sound mind judgement" and my mom had to go through this ridiculous legal process to ensure she held on to his assets and whatnot while she was directly caring for a dying man.

Save your loved ones some grief, create a living will with a trusted lawyer, update it about once a year. It's worth it. There are so many insane snafus one can get into with estranged family members, the state/gov't, medical institutions, etc that make the situation even more difficult and stressful to deal with. Don't expect anyone coming out of the woodwork to act according to honor. They are vultures and know no such kindness.

I did not get either banner looking at the page using Firefox focus on mobile, but this parallax scrolling experience used on this site (and many others)that today's webdevs seem hot to trot over is abysmal. I'm on an 8" tablet and still have to find the sweet spot where the text does not obfuscate the image, so my eyes are unable to quickly dart between both as I read. It's absurd that people think this is a good way to present information. Another commenter replying to you mentioned why not just ditch the JS, and for a site like this I say, right, why not? I'd much rather have the static text and image positions afforded with simple and elegant HTML and CSS tags as opposed to this finicky BS that was clearly tested on maybe one viewport and called good.
