This would be neat to see applied to Vine Robots: https://youtu.be/eLVAMG_3fLg?t=153

---

They talk about the use of the pneumatic vine robots to nav rubble and caves etc - but if the vine robot could evaluate the terrain and use apropriate routing algo based on the nature of the terrain it was doing. they arent using vision necessarily in the vine robots - but if they could use terrain sensors that informed the best routing algo to use/accomplish goal that would be neat.

Another interesting thing about this would be to apply it to where vine-style micro-trenchers could know the patter of the lattice that will best be needed to accomplish whatever the stated newton bracing requirement were - then you could plop relative light foot pads onto a celestial body - then have these vine into the surface in such a way where you can begin to attach larger objects and very easily build foundations to large space structures - plus, as it maps out - you have an exact map of what your mycelium -like base foundation look like.

EDIT:

And you could grow the foundation as need - however, imagine a series of tubes mabe by these vinind robotw - that are later filled in (the robots) with structural hardening material -- you vine your robots into the mountian in sequences - first do a large outer lattice - and strucurally brace it with whatever material - then in the center space - vine into the core and fill those with explosives and tunnel. -- then you can snake through your exploded rubble - see whatst up - and deliver cables and hoses through the vine to a forward location...

A vine robot that tunnels - but its outer layer is a permiable filter and it has capillary features - but basically it unfulrs into being a well and the outer material is expanded do to corrugations in the design allowing debris filteres water to create a layer around the new pipe - and then capillaried up - or a pump in the core at the head of the water-wyrm.

(I need to figure out how to make some of these -- I love them.)

> It's "Slow" because it has more overhead, therefore, by default, I get less performance with more usage than I would with WebGL.

It really depends on how you're using it. If you're writing rendering code as if it's OpenGL (e.g., writes between draw calls) then the WebGPU performance might be comparable to WebGL or even slightly worse. If you render in a way to take advantage of how modern graphics APIs are structured (or OpenGL AZDO-style if you're more familiar), then it should perform better than WebGL for typical use cases.
Thanks for the clarification - see there I go again!

I'm a bit surprised at the short term memory as well. TDA, and Think Or Swim before that all had outages on Occasion.

My experience was that my ToS desktop app was still logged in and kept an active connection, On my Android phone, the Schwab App was able to work (I only use it as a backup) while TOS (My more daily trading app) required me to wipe the local data to get logging in working again (A fix that was required last time Schwab messed up the log-in system).

Schwab has, in the last year or so, made their login much more complex to work with MFA across all apps. This probably have their log in servers doing a lot more work than they projected.

Ask HN: Are .dev domains worth anything?
Some five years ago, Google introduced the .dev TLD and there was a bit of hype around it. Some people assumed it would become a popular top-level domain for developer-oriented products — similar to .io but without being tied to a weird geographical region.

Well, I assumed that anyway, and grabbed a few premium .dev domains (common English words with three or four letters). And as usually happens to domain registrations, my big plans for these domains came to nothing.

Looking around, it doesn't seem like .dev has caught on like one might have imagined. Do you see value in it at this point? Would you use this TLD for a product, or is the old advice of compromising on domain name memorability to get a .com still valid?

There was a story in the NY Times six months ago about colleges in the US going with geothermal. Many are putting in shallow geothermal to be used with heat pumps (depth ~900 feet), but Cornell has also been looking at true geothermal with an exploratory well to nearly 10,000 feet (bottom temperature was 82 C).

Nelson's faming here pretty much sums up how I feel about the whole ball of wax myself, a musician, and someone who started their career working for a major national concert promotor, worked for two streaming music services and who participates in a local music scene as performer, supporter and occasional promotor:

"""

The problem isn’t just the ever-decreasing viability of even established, popular artists keeping food on the table. There is also a cultural poverty that attends the streaming economy. There is the ruthless profit maximization and the constant steering of listeners toward the same music. There is the lock-step social engineering and manufactured consensus. There is the escalating — and demeaning — sense of music being treated as a utility that need not be meaningfully engaged with.

For now, we still do not have a complete understanding of any living cell.

The mycoplasmas have some of the simplest possible cells, so, as you suggest, they are good candidates for the first cells whose organization and functions will become completely known.

While it is unlikely that understanding a mycoplasma would provide direct information about the causes of senescence in any multicellular organism, there is no doubt that when either a mycoplasma or another of the simplest bacteria will become completely known, that will bring a huge jump in the knowledge about all living beings and from that moment on it will become much easier to discover the causes of senescence and how it might be prevented.

There are bacteria that have extraordinarily efficient mechanisms for DNA repair, so there is no doubt that it should be possible to improve the design of human cells to avoid the accumulation of genetic errors. However, this will not happen in a few years, but in at most a century from now it is very likely that this would be possible.

Just to follow up, what is your method for finding those tabs again?

Imagine a scenario where you have 200 tabs open. Unlike bookmarks, they aren’t categorized into folders.

I imagine one can keyword search all open tabs, but that’s kinda like googling them again except you have a filter on what you’ve opened. When would you ever want to do that vs just doing a new google search?

I can sort of imagine having open tabs as a kind of “saved state” when doing research without the additional hassle of curating bookmarks (adding/deleting/classifying). But just curious if people think of it this way.

Geothermal doesn't cool the center of the Earth; it cools the crust around the wells. The effect farther away is miniscule on any reasonable timescale. Think of it as mining crust heat.
A heck of a wild bug chase
I work for a company that has a .dev domain, and nearly worked for another that has one as well. I think .dev is perfectly fine for developer tooling websites but it probably doesn't have super wide appeal.

It's a great way for a specific niche to get good branding. Getting a .com is absurd these days. If there is a viable, short, and memorable alternative TLD, it is often worth considering.

Do the TLDs hold value? I'm not sure, I think that's a fairly tough argument to make with .com as well.

I think this is an example of what I’d call the “Blade Runner” effect: if you show Blade Runner to someone who’s never seen it before, they’re going to think it looks vaguely derivative, because they live in a post-Blade Runner world, in which everything looks like Blade Runner.

A report on the status and health of friendship in America
Many of us are non-graphics programmers interested in learning to benefit from CUDA-style parallelization. I’ve read they’re mostly incompatible, though. I know there’s vendors supporting OpenCL and Vulkan. I didn’t see many AI projects using them, though. Makes me think cross-platform approaches aren’t great for some reason.

My questions: are there good, native implementations of WebGPU where learning it can replace learning CUDA or ROC for good, GPU utilization? If not, would a book like this teach us enough to easily pick up CUDA etc? Or are they very different to the point we’re better off learning the GPU-specific libraries?
Whoops, thanks for the correction. I was looking at end-user electricity consumption so it didn't include all the losses involved.

That's staggering at first glance. So much energy!

But then, I wonder how much it would really matter if we were harvesting that energy to move objects around on earth and turn on LEDs vs letting it dissipate into space. So I'm still skeptical of the concern.
It has. Very few consumers care about this, otherwise LTS guarantees would be a way to boost sales, or publishers would build more of a reputation around that. If there were actually a regulation as proposed, it'd be "tyranny of the minority." A few people with a lot of time and passion forcing an industry to work the way they want.
That is an excellent comparison. And with the assumption that geothermal wells can last longer (the wells for my geothermal HVAC system were rated 50+ years, although I presume my wells and the types of wells needed for a 400MW plant are far different) then this is actually pretty decent.
Since at least two people noticed, I would just say that the insert-select-insert approach was added later, after I took some inspiration from Django's implementation of get_or_create.
Assuming due to Intel's stock debacle, there will be a significant spotlight on CHIPS subsidy receivers. I understand it takes a very long time to get things going for large manufacturing changes, but I'm curious how things are going timeline wise.

It would be cool to have large high-tech manufacturing industry back in NA, but on the other hand, it's hard for me to grasp the economics behind it. My understanding was due to minimum wage laws, high prices, non-existent infrastructure and etc., it wouldn't be profitable to sell them outside of US (and that's why it was offshored, along with the Japanese/Taiwanese companies just being better quality wise). Why would a North American, European or Asian company that design hardware buy these chips when they'll always be more expensive than anything that's built overseas?

Also the jobs are fairly specialized, unlike Amazon warehouse jobs, where you can make $20/hr. So not sure how attractive the positions are for the local talent. I guess, if the governments continuously subsidized it, it would make sense. But it's not like agriculture industry, where one could make the "food security" argument.
I can't try this because my OS version is too old. I'm confident the app marketing, specifically the idea "Your favorite shortcuts at your mousetip!," is appropriate for how most would use it, though my case would be different.

My first thought was how this would be helpful for the app commands I use just enough to want quickly accessible but not often enough that I remember the keyboard shortcuts. I'll give this a try when my Mac/OS are compatible. Best of luck.
> IPv6 can get rid of NAT which is one of the most annoying hurdles.

Right.

> It unlocks the type of use case where technical people can host something from home for fun, although many can’t access it because both parties need ipv6.

At this point, that's an obstacle, but at some future point hopefully IPv6 will hit a critical mass and network effects will take off because there'll be enough stuff that _doesn't work without IPv6_, so customers will demand it.

> if you set your sights higher and want to build true p2p apps for non-techies

Definitely.

Restoring the universal endpoint-to-endpoint connectivity on the IP network overcomes a _major hurdle_, a hurdle that's so big and longstanding that people have come to just assume its existence and fear and removal… but it certainly doesn't solve all the problems.

> or if you want “roaming” servers (say an FTP server on your laptop)

https://en.wikipedia.org/wiki/Multipath_TCP will take a big dent out of this, I think.

> - Opening up ports in both a residential router and sometimes the OS or 3p firewall. Most people don’t know what a port is.

I mean, UPnP makes big improvements in this area, but a lot of devices stupidly don't handle it, or block it for alleged security reasons. Frustrating.

> - DNS & certs which require a domain name and a fixed connection (if the peer moves around across networks, eg a laptop or phone, DNS is not responsive enough)

There's no real reason why TLS clients _must_ only trust certs when they see that the CN or SAN matches the _domain name_ through which they looked up the IP address. I think that with a better issuing infrastructure and UX, a TOFU-based (https://en.wikipedia.org/wiki/Trust_on_first_use) approach to self-signed certs for peer-to-peer services could be both comprehensible for non-techies and highly secure.
That is most cool. Thanks for posting.
Part of the problem is codesharing, you have to use two flight numbers for the same flight. The whole practice is confusing and I don't think it should be allowed, except in the rarest of circumstances. The seat quality is also suspect at best, when you're not directly buying from the operating carrier.
The craziest conclusion I've seen longevity experts narrow in on is the mTOR == cancer hypothesis. And the logic leaps are astounding:

1. Rapamycin inhibits expression of mTOR. (verified)

2. Rapamycin extends lifespan of cancer-encoded laboratory rats. (verified)

3. Therefore, activation of mTOR causes cancer. (???)

4. Therefore, stop eating protein.

The leap from 2 to 3 is incredible. These guys aren't considering the possibility that Rapamycin might have other cancer-inhibiting properties via other pathways. They're just assuming that because the R in mTOR stands for Rapamycin, that's the only thing the drug does.
Welcome to Denmark. Pardon the weather. The danish petition site is here: https://borgerforslag.dk/

Of 1843 petitions, 52 have been presented in the Folketing, and some of those are silly/unrealistic, like removing tax on fuel. Others had very widespread support and a lot of news coverage, like banning genital mutilation of children, but nothing came of that. I think the enthusiasm for this initiative has declined greatly, since only one petition got enough votes (50.000) in 2024 to reach the Folketing. People have realised it's pointless.

yet another instance where apple's unclear support policies will cause more confusion. Was iOS 15 impacted, and will this be backported? Nobody knows. 15.8.3 was announced the same day as 16.7.9 but with zero CVE notes, so if you have one of these: iPhone 6s (all models), iPhone 7 (all models), iPhone SE (1st generation), iPad Air 2, iPad mini (4th generation), and iPod touch (7th generation), it is unclear if you're receiving security fixes.

WebGL compute was not viable, and only existed as an engineering prototype with lots of rough edges. There were a bunch of hard problems that needed to get solved to ship WebGPU. Perhaps in an alternate universe, that work could have been done in the context of WebGL, but it didn't.

I'll give one example (as it's one I was personally invested in). Doing a barrier in non-uniform control flow is wildly unsafe undefined behavior (I've had it reboot my computer, and it's easy to believe it could be exploited by malicious actors). To make these barriers safe WebGPU does a "uniformity analysis." However, that in turn required adding uniform broadcast intrinsic to the shader language, otherwise a class of algorithms would be impossible to express.

As I say, it's plausible this kind of work could have been done as extensions to WebGL, but I think the end result would have been a lot less compelling than what we have now.

1. Licenses
2. Air traffic control & routing for personal crafts
3. Landing / Takeoff / Turbulence (weather) - where typically most of the human skill today is used in for commercial flights.
4. and probably the one for interface design and overall autonomous systems - human decision making + autonomous systems really have a difficult time working in tandem - fully autonomous is less risky at an aggregate level but puts onus and more of the blame on the company / maker versus human-in-the-loop.
Sorry, I should have worded my comment better.

It was not to detract from the need for new and renewable sources of power, but rather surprise at how little power you get from each well, and the cost of drilling each of them.
> Keep in mind that my point was specifically about high stakes elections and you reacted to it without making that limitation.

I was also thinking of high stakes elections when I wrote my response to you, even if I did not explicitly say so.

> I have never seen an election where a vote isn't ticking or checking a ballot box, maybe this is different in Finland?

In Finland you typically scribble down a number. Yes, it's harder to accidentally spoil a ballot if you only need to tick or check a box.

> Having worked with computer vision systems and programmed them I can tell you there is no 100% guarantuee that the result that air-gapped machine showed the voter in the voting both is the same as what is reached later – not even if we assume the exact same machine to be used for the count.

But in this hypothetical example the computer is not used to count the votes, it is used to write on paper. Because a computer can unambiguously draw the number "7" on a piece of paper, and the voter can unambiguously verify that the number is correct.

I wouldn't call it such either.

> If we are to look for a good comparison we should compare the best way to do paper based elections to the best way to do it digitally and draw our comparisons from that.

And that is what I did in my thesis. The best way to do in-person paper based elections is (a variant of) Floating Receipts, which is a better system than (a variant of) Civitas, which is the best way to do remote e-voting.

At this point I am very confused what you feel disagree about. We went into the weeds over some minor issue regarding spoiled ballots, and I feel like you are drawing way more conclusions from that than you should.
I have used z3 for a job scheduling problem. I had a piece of equipment which can handle capacity X, jobs come in at known intervals and are available for given durations of varying lengths, some jobs come in multiple times, some jobs must be done above all others. Which jobs should be assigned to the equipment to maximize completed jobs while not missing the high priority entries?

Numbers were such that you could only ever handle a fraction of the possible work. The throughout of a good allocation could be significantly higher than a naive one.
