Ask HN: Open-Source DIY Robot
Hi there!

I am looking for a Open Source DIY robot project I can print on 3D printer and use something like RaspberryPi or RaspberryPi Zero or Nvidia Jetson to add some AI stuff inside.

Is there something you can recommend?
Something like Loona https://www.youtube.com/watch?v=5BUa8lGpREY or Vector https://www.youtube.com/watch?v=lZo2Ny61M1U
> and intercepting hypersonic vehicles at scale is still tremendously difficult

...as far as you know. Working purely from declassified information, which is all any of us have; but also in clear awareness of the clear forty-year gap between the frontier of declassified military secrets, and what would be the current classified state of the art.

> dead man's switch

I think you missed the part about, uh, the whole other half of how current doctrine works.

Do you know why having cyber supremacy is ranked above having space supremacy?

Because, if you have a sufficiently-good APT, you can have it press buttons! Buttons in places you'll never be able to get a spy inside at the right time! Buttons that subtly break all production missiles at the factory in ways undetectable until launch! Buttons that were meant to give civilian command oversight the emergency-override capability to cancel a pending launch of an insurrectionist military!

(Or, if you don't think that's plausible: "buttons" on a commander's personal cell phone, that calls a staff member of his and deepfakes their voice to tell the staffer to physically hit an air-gapped e-stop button. Add to the theatre by having the APT cut off Milnet-equivalent services at the time, so that a personal cellphone would be the obvious workaround.)

And of course, with previous APTs, you can also steal or more likely, create and plant all the blackmail material you want — to turn previously clean-and-trustworthy "keyholders", into your catspaws, willing to not turn the key when told. (Spies could do this too, but APTs can do it at scale.)

> There's a reason every single nuclear armed state still stands in some form.

Because none of them have yet stepped out of line enough for a major power who has anything "better than nukes" to see the point in showing their hand to their own much stronger opponents who have also moved on to playing this "better than nukes" poker game. (Nobody has had to show their hand at any point in the game so far. It's just been bluffing and folding. Nobody wants to be the first.)

For example, while North Korea has nukes, it has no answer to even basic 1990s-level orbital EMINT; and no functional Navy, let alone long-dive nuclear submarines to serve as untrackable launch platforms. All of NK's nuke launch sites are known — and so could be targeted for bombardment (with plain-old non-nuclear payloads!) in advance of launch, the moment they seem to be getting ready to shoot anyone.

The only reason it hasn't happened already, is that the action of taking the nuke sites out involves cards nobody wants to lay on the table until they have to. It's a move that weakens you, strategically. Although it's something that would almost certainly happen — many times over — the moment a hot war between larger players begins, once all those cards become destined to come out regardless.
I use Inkscape to create simple yet high-quality SVG images for technical presentations/talks. It's great and it integrates somewhat easily with LaTeX too.
Sadly, they don’t need to. The people who actually buy into this are so stup*d that it’s not worth spending a penny more than a lousy eyes blinding “party”
The parent probably doesn't understand what you're talking about. Case in point.

> And I think Americans are plenty aligned with academia, except the small fraction of ultra-conservative republicans who are against everything that's not in their 2000 year old handbook.

The average American completely ignored academia during the COVID pandemic. America's rates of compliance were way lower than other similar countries.
>RISC-V is much more of a threat to ARM microcontroller vendors (STMicro, NXP, Atmel et. al.)

How is RISC-V threatening them exactly? They can (and should) switch to RISC-V.

Note NXP is already doing so[0], and that Atmel is part of Microchip[1].

I'm not sure I get you. What do you mean the "latest version of the method"? And why shouldn't code from 18 months ago not work? Some minimal regression testing should be in place for production code, and it is probably also used regularly.

So, yes seeing e.g. how "CSV export for class A" is implemented is a great guide for implementing "CSV export for class B".
essentially. a whole industry cropped up around hosting them, which mostly defeats the point

there are a lot of NFTs that are better implementations, the primary improvement being that there is no external hosting and they build the visual data into the smart contract function for a renderer to interpret

Ive done a lot with SVGs that way. others upload dependendies like three.js on the blockchain in other smart contracts, so when called they can return into yours and you have more sophisticated renders

I think artblocks does something like that, not sure

Most of the financial sector NFTs have an onchain svg too, like all the Uniswap liquidity pools

first movers are often poorer implementations of the technology, its up to the consumers to discern and if they dont then there is no incentive to act differently

> only if you are a pro driver you actually can outperform ABS

I'd imagine even then, this only applied 20 years ago when ABS was still relatively primitive. I've had only triggered the ABS on my ~2015 car a couple of times but I don't think I could have done significantly better than it even in a non-panic situation.
Building an open source sync backend for Logseq: https://github.com/bcspragu/logseq-sync

I'm a big fan of Logseq for keeping track of useful information and tasks and stuff, but the file-based (or Git-based) syncing has sharp edges, and the actual Logseq Sync feature has a proprietary backend, so I've been enjoying figuring out how the protocol works and building an OSS implementation.
I don’t know if I fit into the reasons here.

I blocked chrome from updating because it would peg my cpu a few times per week. After the 10th time, I stopped the update and haven’t had that problem yet.

There aren’t really any new features from chrome I want for weekly updates and the suckiness of their updater. I just reinstall every few years.

I also find that updates are usually a pain. They do dumb stuff with cpu and disk. They consume a lot of data (my isp caps me at a TB) and so aren’t a good value.

“Security” isn’t a real reason for super frequent updates.

Unfortunately, I wouldn’t expect the average guy to know how to tell whether a UV bulb is safe (regular non-quartz glass helps a lot) or that dangerous ones are sold without warnings.
I remember both DAK and JS&A -- I always wondered why their catalogs seemed so similar and this explained it.

I remember buying a handheld electronic chess game in the mid 1980s from one of those catalogs -- I can't remember if it was DAK or JS&A though.
I haven't really followed the lab leak theory but it's so frustrating when claims of "racist undercurrents" or "dog whistling" are made without substantial evidence. Those terms are just used to halt constructive dialogue and make unsubstantiated accusations. And they are often an instance of the following logical fallacy: "Racists support X, therefore supporting X is racist."

Those terms were frequently used to shut down discussion when the Quebec government made the decision to prohibit certain public employees from displaying religious symbols a few years ago.
IME and IMHO that's not reality. People do care about the truth, as well as power, and many other things. They generally are truthful. It's also (enlightened) self interest and we are highly evolved social beings, able to organize on the scale of billions.

The idea that we are only or mostly our worst, most self-destructive instincts and not, for a equally likely example, only our best instincts, is an odd one, but people love to think it these days.
Homeopathy is based on water memory wherein diluting the original material increases the effectiveness of the dosage.

Even if this is true (no study has shown it is, many have shown there is no effect) why doesn't the mechanisms employed by homeopathic medicine match this theory?

Many homeopathic medicines are available in pill form. Not water pills but sugar pills. What is the scientific basis for water memory that lines up with using sugar pills?

Additionally dilution is expensive and not actually done by homeopathic medicine manufacturers. Instead unpurified water is ran through a container which is shoken and emptied completely. The assumption being that upon refilling the container a 1:100 dilution will be created.

Once more I point out, what does this have to do with the proposed scientific basis?

Even if there were a "method to the madness" with regards to Homeopathies "less than one molecule in all of Earth's water" dilutions: the reality of homeopathic medicine creation is they don't even use fresh water for each dosage often reusing the same water to save on fresh water costs.

So the best you can say is while the psuedoscience might be pseudoscience and not just made up (note it is certainly made up) however the manufacturing industry is unable to even reach that low bar of psuedoscience.

Instead the manufacturing here is simply abusing a whole in FDA regulation made by a questionable ruling by the Supreme Court. "As long as the magic words 'Not for the treatment of any disease' exists you can put any unregulated substance next to regulated medicine".
Corporation is a mechanism to provide profits to the shareholders, while staying compliant with the appropriate rules and regulations.

The corporations is not a machine to optimize for personal views of the founders, unless there are no other shareholders, or unless all the other shareholders are in agreement (something that might be impossible to achieve when amount of shareholders crosses certain threshold).

In other words, if you are accepting outside shareholders into your company, you are no longer allowed to make any decisions for any other reason than profit, not unless other shareholders would consent to it. This is the law.

However, as a shareholder, you have the right to choose who you would like to have on the board, for any sort of arbitrary reasons.

There is a reason so many open source projects require squashing.

Ain't nobody got time for that shit.
I used to have pretty much a whole bookshelf shelf at home of catalogs that arrived by the pound around Christmas. Even if my buying was usually with the boring clothing regulars pre-Web, it was entertainment. I buy less stuff generally, can better just search for stuff, and, as you say, smartphones have cut into the market for various single-purpose electronics.
But we aren't discussing penalties for harsher chemicals. RoundUp is getting undue legal attention relative to the risk it carries, and farmers are already under enormous pressure to switch to more harmful herbicides. (There are no less harmful broad-spectrum herbicides. Glyphosate is the safest we've got.)
Citizen science! It's great when people realize they can answer their own questions with observation and data, and for activism because data is a powerful story. One friend of mine started https://publiclab.org to feed this, and another is doing data journalism to highlight holes in the government's environmental data. https://www.muckrock.com/project/
A rules-configurable sensor tool I made a long time ago was used by a non-profit to provide a service that logged NYC landlords' violations of thermostat settings.

These combined with the experience of exploring the natural world in my kids' school's makerspace, has made me come back to making sensor tools for the people - would love to hear from others how they use sensor data for change: https://supermechanical.com/pickup
The dementia is probably caused by the underlying mechanism.

The motor symptoms of Parkinson’s are caused by the loss of dopamine producing neurons in the motor cortex. The loss of those neurons for any reason would cause Parkinson style motor symptoms.

The cause of the loss of dopamine producing neurons in standard Parkinson’s is not understood, but appears to be related to a thing called Lewy bodies which are deposits of a protein called alpha-synuclein. The presence of Lewy bodies outside of the motor cortex is correlated with a disease called Lewy body dementia rather than Parkinson’s.

Most likely, there is a underlying process that causes neuron loss that slowly spreads. This process frequently starts in the motor cortex resulting in Parkinson’s, but sometimes starts elsewhere causing Lewy body dementia. Dementia in a person with Parkinson’s likely occurs when the process starts spreading beyond the motor cortex which effectively causes Lewy body dementia now that it is no longer isolated to the motor cortex.
Even if you're doing something with strong network effects you've got to consider cases like facebook which weren't first movers in markets where there are super strong network effects and yet still won. You're not really going to have a 'community' based moat for PDF analyzer tool #5 or retrieval augmented generation knowledgebase parser #300. You're not gonna have a moat based on much else either...
Yeah but then you have non CLA-ed code in the original codebase which in the context of an AGPL+CLA project, now it's just AGPL and their upstream has to be maintained separate from their proprietary offering.

So in that sense, it's no different than if the maintainers was just a collection of open source contributors rather than a corporation. They can integrate your changes as long as they comply with the license but they can't meaningfully profit off of them outside of any service you yourself code be providing as well.

I don't mind merge commits, it's the 100 tiny individual commits some developers seem to like to do that really clutters things up. Yes, I know, git squash is a thing, but not committing until the feature is working and ready to commit is also a thing.

Agreed. The accretion theory for both star and black hole formation is not in good shape.
If a strategy requires humans to be virtuous AND vigilant it is doomed to failure.

Sorry, but I don’t buy that. By the same principle, there’s also no point in writing unit tests or defining static types or having code reviews, all of which require thought and extra work, yet can yield considerable dividends when done even moderately well.

I rarely use history and prefer merge/squash, with automated CI tools, and tests. "Why" is kept in doc strings, comments, specs, and story tickets.

The argument for a tidy history isn’t just about a different place to explain a change. It’s about presenting work in clearly defined, meaningful steps to other readers like code reviewers, or perhaps someone who found these commits later through `git blame` on a problematic line of code or `git bisect` after a regression. It’s about each commit representing a complete, self-contained change that could later be reverted, or cherry-picked or merged to another branch.

I submit that, if your code is so complex that diagnosing a bug is a major research project rather than moving forward with a few extra/modified lines of obvious fix, then that is the problem to focus on.

Some problems have a lot of essential complexity. The code to solve them necessarily has at least the same degree of complexity. Sooner or later, there will probably be a change to that code with an unintended consequence for something else. Keeping the code and its history tidy and systematic is, IMHO, how you avoid those investigations becoming major research projects.
Reminds me of an urban legend about a rave party in Russia where the laser show blinded people in the audience.
> if all the mass of the black hole were spread out evenly throughout it.

That seems like a weird condition. "Average density" is pretty well-defined and doesn't need even spreading.

Even more, isn't the distribution of mass within a black hole a meaningless question? There's no information coming from the black hole, for an external observer it literally doesn't matter how the matter is arranged within.
> even if people like to deny it because of fears of racism or being accused as one.

Your only argument is to make up disparagement of people who disagree.
> Is there even any interpretation that would allow this to be seen as anything different than industrial style IP infringement?

Yes. We funded the mujahideen while their countries were being invaded by the USSR. Would your solution be to let Russia colonize other countries at their leisure? Once again, taking money to defend your country and then, when you're done, coming to wreak havoc in the US is going to lead to war... duh

Next time be grateful that Uncle Sam helped you keep your God-forsaken land
Not unhireable, but you are probably going to have to find an employer where the fit is good both ways. It may frustrate finding something else, but when you do it will be good.

BUT I am going to ask as a rhetorical question, why isn't your startup making money? I can tell you why mine isn't, I made a product only one customer wants. Which isn't really a product. Maybe a pivot or two...
That's interesting... I don't get any captchas.

There have been reports of UV-C bulbs being repackaged as "party lights" and sold on eBay/Amazon/etc. So it is possible they had no idea.
The biggest problem with Wikipedia is that it ignores a lot of factual scientific publications that wiki-editors are unable to comprehend and then blindly trusts "notable" sources published in junky paper articles while those papers regularly caught outright lying in their articles.
I believe one of the reasons why so many people get away with the black culture dog whistle is American history kinda ignores the entire period between the end of the civil war and the start of WWII. We learn some about the Jim Crow era, but it's kind of neglected that slavery didn't stop at all. If you say 'Slavery actually ended in WWII", I do believe most people would be surprised. And it reframes the argument from slavery ended a long time ago, to things were really still total shit until your (black) grandparents generation (and not much better till the civil rights movements after that).

Now, turning this back to Russia, is seemingly Russia has always had the idea that it's outer population is a gigantic meat shield to protect Moscow. There are a number of authors and videos on this topic and I'm not going to link any particular ones. This said in the current war with Ukraine we see this in practice, as huge amount of the soldiers being used are not from the Moscow area, but the more minority areas farther away from the capital.
They do this with Discords and bots to make interest look high, I can't believe they didn't think to do it with an in person event. Actors must be a bigger pain to get than bots?
This feels like simply a system prompt generator. It gives you a survey to generate a decent system prompt from, then staples that prompt to the front of any interactions with the GPT.

It doesn't seem to be much smarter than a simple "tell me how I should interpret inputs from the user."
The English Wikipedia might (or might not) have achieved this but certainly the Croatian and Polish were caught to be heavily influenced by right wing extremists, the Hungarian was not yet because no one gives a damn.

But my recipe of adding anything to Wikipedia still stands, I adopted it from an article added by Hungarian nationalists: while you must source things, the quality of the source is not checked. So take an obscure book, obviously not in English and claim your fact comes from it. No one will try to dig up a small run German book decades or even hundreds of years old to verify. Or will be able to.

The thing is, the people Wikipedia successfully did drive out are actual experts -- or rather they never came. The no credentials are accepted policy makes sure the experts stay away in droves. Imagine someone putting in decades of work to gain expertise in a field being told they need to argue with a neckbeard with too much time on their hands. No thanks.
>Are we just lucky that this object happens to be directly observable?

Pretty much, yes.

There is plenty we have trouble viewing (e.g. objects that our own galactic plane obstructs), but the universe is Big. Which, luckily for us, means that even though plenty is hidden from our view, there's a lot that we can still observe.

Sure!

Go to that same CeraVe brand store, click on Face Moisturizers, scroll to the bottom to find “CeraVe Anti Aging Face Cream with SPF” and click on that. For me (right now) the default shipper and seller is a third party called “Justsomedeals”.
I think what they're saying, though, is that constructive dialogue is impossible on this topic, making it a poor fit for Wikipedia regardless of one's personal opinions and beliefs on the subject.

Which, until the Chinese decide to be more forthcoming with the world, is likely true. We can't know, and we won't know, because they won't talk.
India has a pretty strict neutrality policy. But you can bet if China waged an expansionist war they would be on the same side as those fighting China.
>which is high performance processors that can natively run x86 binaries

The latter, maybe.

The former, as soon as 2024 (e.g. Tenstorrent Ascalon)
Wikipedia is fairly transparent about how they spend the money. Anyone donating can easily check and donate to their liking. Stop making up random 10% etc.

I never understand this obsession that people have with non profit funding. A weird way of counting efficiency by counting how every dollar spend and not really the value produced.

Clearly Wikipedia is one of the most useful things in the world. They would be more "efficient" wrt money most people give to them even if they were to set fire to a large portion of it.
