The article also explains that the natural way to look at this property is in terms of matrix exponentials/logarithm.

The space of rotation matrices is not a linear space. It's obvious that interpolation is meaningless there. The space of skew symmetric matrices is linear, so you can interpolate the generators of rotations naturally.

Without this perspective, how do you even begin to understand what this interpolation does or what it actually means?
> and the fact that nvidia is worth more than them

You scared me. I know the market is hyping up Nvidia hard, but if it was really worth more than Apple then things would really be crazy.

AAPL market cap is still 10x NVDA’s (3.2T vs 330B), so not yet too crazy.

Update: Nvda is at 3.24T. ddg “nvda market cap” shows the wrong amount. It probably doesn’t take the stock split into account. Djeez. That’s. Well, time to short.
I will rather work with somebody using Source Tree and clears his code before committing from unnecessary, irrelevant or outright wrong changes, than with somebody who knows 3 commands (git add ., git commit -m "some changes", git push) and repeats them without thinking the moment code on his side is "finished", thus committing also changes which are completely irrelevant to what such person was working on.
It's a literal tragedy of the commons
Yep, those are just forms of batteries though so I think my point stands? There is lots of cool stuff you can do with PV+TES without even needing true thermal batteries, just using smart electric hot water heaters and dispatch, and even cooler things if you set up a peer-to-peer network of them! But again, that just goes to the point that other challenges have overtaken solar efficiency in urgency (which is a great thing to reflect on!)
@erik_seaberg the lack of success in finding a universal grammar is a logical leap. The failure to find something does not necessarily mean it doesn't exist. Language is powerful for expressing abstract ideas without explicitly saying them, which suggests language more than "lossy" compression because it's more similar to Shannon's lossless compression with prefix codes. I see where you're coming from though.

@Felcon If language is a mechanism for expressing ideas and reasoning, it should reflect our cognitive processes that generate those ideas, so " [...] Just because you use a mechanism for expressing your ideas and reasoning, doesn't mean that underlying reality has to confirm in any way to it" is a bit contradictory. Are our cognitive processes not included in reality?

The existance of a universal grammar is a specific hypothesis that requires empirical evidence. It's tiring to hear Chomsky's ideas parroted despite no empirical framework to stand on. What ideas could we be lacking? This argument is similar to String Theory proponents who kept pulling ideas out of the ether to support an unsubstantiated theory.
Journalism does not cost money. Running a company that is attempting to profit off of publishing costs money. Or have you never read anything produced at no benefit to the author that has ever informed you? I think you're putting the cart before the horse, and advertising supported journalism has always existed, and these companies would rather collect CPM from google than do legitimate placement of ads in their own content, which would be unblockable.

No, what I'm saying is, the existence of institutions that can publish at scale has no impact on whether individuals can do it or not. I can write code whether Google exists or doesn't. In that sense it belongs to individuals.
Its mind blowingly shocking to me, how are they updating the software from so far away? how are they fixing the issues?
Against The Travel Neck Pillow
I think that is implied in my comment. You can send me whatever request you want, within the bounds of the law. I get to decide, within the bounds of the law, how I respond. Demanding I provide a particular response to every client (and what the parent commenter and others seem to be arguing for) is where I take exception.
Is that possible? I'm not sure if I've ever read code like that before, but maybe that's just me.
> I worry that the ‘unthinkable’ nature of nukes is being used to push red lines as far as possible.

That's kinda the point. The US has been dedicated to strategic arms reduction treaties for decades, with the express intent of limiting a missile-gap mentality from taking over again. In particular, the only real reason the United States can muster for justifying nuclear weapons is retaliatory strikes; there's very little practical use for them besides saber-rattling, because once you press the big red button every single country is going to consider you the escalating party.

Both the United States and Russia are replete with tactical standoff strike weaponry that is non-nuclear and well-suited for the kind of conflict they want to fight. Nuking targets in Ukraine would not only be unnecessary, but it would annihilate Putin's cover of territorial aggression and almost certainly qualify as inhumane and disproportionate escalation. NATO would have full casus belli on Russia and no "red line" threats could stop the retaliatory strikes on their silos and airbases.

I think both of you have lost the script on what a nuclear strike actually represents, in international realpolitik. Whatever megaton you dial, nukes are a red flag will push every ally and enemy you have to the brink. If you lack popular support on the global stage (like Russia), there's no guarantee you'll survive a second-strike attack long enough to get what you wanted. Putin specifically despises NATO because it guarantees Russia will be crippled in the event they cross the nuclear boundary.

For the applications I see clients wanting to buy, no. Both the maturity and cost-saving potential of GenAI are greatly over-hyped.

From a non-tech business perspective, I expect the interest in GenAI to decline by years end. It's just not materialising the value stakeholders are expecting to see for the exorbitant investment.
I think you are not reasoning correctly here

Adding features to a code means it was incomplete. Misunderstanding input/output usually means it is poorly documented or lacked a good API. A good API works at the surface (in/out) and not in the volume.

Really good code solves a problem completely. I have worked with such code and yes almost nobody ever goes into this code (and makes changes).
Are you saying there are CEOs who won't lie to make their stock price go up?

Thanks for the link, that's fantastic to hear!

I'm seriously sick of that whole "laundering copyright via AI"-grift - and the destruction of the creative industry is already pretty noticable. All the creatives who brought us all those wonderful masterworks with lots of thought and talent behind, they're all going bankrupt and getting fired right now.

It's truly a tragedy - the loss of art is so much more serious than people seem to think it is, considering how integral all kinds of creative works are to a modern human live. Just imagine all of that being without any thought, just statistically optimized for enjoyment... ugh.
> It sure must be encrypted?

I very much doubt it. There are hard physics limitations at play. Nasa's Deep Space Network [0] is the only system on Earth capable of communicating with the Voyager probes. If an attacker managed to secretly construct a 70-meter dish and reverse-engineer a poorly-documented 50 year old protocol I would only be impressed.

> Bad example because it takes significantly more expertise to model the savings from triple paned window with low-e coating and vacuum sealing vs double paned vs single paned (ie it requires a proper building energy model in eg EnergyPlus). Also bad because the triple paned window might be immediately disqualified by the budget constraint above.

I'm confused by this as that is exactly the point made. :)

I was watching a NASA iTech talk if memory serves about vacuum windows. He opened with an overview of the market and adoption trends and was quite flustered. Small market, little in the way of R&D and many challenges in manufacturing them in the US.

One of the things that flustered him is being told by sales reps that those types of windows are "pointless and not worth it" and so on. Digging deeper the reason he was steered away from them is simply because they were up not as lucrative to sell in that moment at time for that provider. I can try and dig that up if you want as I recall this anecdote vividly and my thinking diverged from yours in that moment.

Turns out most people have no idea what any of it means you see? So indeed friction, perverse incentives, financing, lack of consumer education and so on. Some terribly sad amount of people still opt for single pane instead of double which shouldn't make any kind of sense.

Remember also that people often move houses. Anyway the upfront cost ended up dominating rather than the payback period. Folks aren't that rational or liquid.

Out of curiosity try modeling it out and pitching it as a choice if you know anybody looking;

Chinese panels <20% efficiency, cost X, payback period Y vs Unobtanium panels 25% efficient, Cost X+, Y++.

But don't try to steer them or mention the payback period unless asked. It isn't as straightforward as we would hope.

On a related note, I'm a little shocked to discover that MED/OctaMED apparently has new/current commercial support?!

You're right. Carolina Hernandez speadheaded this initiative to take screenshots of your desktop every few seconds or minutes and transcribe the result into a regular local sqlite database.
"Text message" meaning "sends sms". RCS is (for all intents and purposes) an upgrade to SMS. How many Linux desktops have a phone number and a SIM card (or equivalent)?

Signal made the design choice to require a phone number to operate. Just as with Google Messages, Whatsapp, telegram, and most others, the desktop application for Signal requires you to auth via the app on your phone, which is authed to the network via your phone number.

iMessage is tied to an Apple ID and doesn't require you to have a phone at all.
Show HN: FlyOnTime, a Chrome Extension that helps you book better flights
If you're anything like me you've realized that US air travel has become quite a raw deal recently. Macroeconomic forces aside, the customer experience sucks.

Flights are delayed all the time, connections are missed, and the prices are still sky-high (no pun intended).

Digging into the data I found that not all flights are created equal. You've probably heard the phrase "I flew X, they are way better than Y" where X could be Delta and Y could be Spirit.

So I made a Chrome Extension that shows you on hover the predicted probability of delay and cancellation for every single US domestic flight.

I think that type of phone was everywhere because the national telecom provider (PTT at the time) handed them out with a subscription plan? I remember seeing "property of PTT" stickers on them.
Friendly Neighborhood Handyman checking in here. Average Home Depot customer? Absolutely not unless there's some plan to quadruple suburban emergency services budgets. On the other hand I get pretty tired of sneaking around local restrictions on electrical work. Residential electrical work isn't exactly complex and I can't devote a couple years to working as someone else's laborer to get a cert. I'm perfectly capable of handling 100% of a residential solar install (including battery backup) and it's aggravating af to have to go find an electrician to bribe to get permits and inspections.
Many users were paying for this from a 3rd party already (rewindAI)
Using copyrighted data in training LLMs is allowed in the European Union, unless the copyright holder specifically opts out. This is in the recent Artificial Intelligence Act, which defines AI training as a type of "data mining" being covered by the EU Directive 2019/790 Article 4.

The problem is that there is no designated protocol for opting out.
There are a bunch of protocols pushed by different entities, and support is fragmented even where there is intent to do the right thing. This means of course that they don't work in practice.

An example: The most well known out-out protocol might be DeviantArt's "noai" and "noimageai" tags that could be in HTTP and/or HTML headers [1].
The web site Cara.app has got a large influx of artists recently because of its anti-AI stance. Cara.app puts only a "noai" metadata tag in HTML headers of pages that link to images but not in any HTTP response headers.
Spawning.ai's "datadiligence" library for web crawlers [2] searchers for "noai" tags in HTTP response headers of image files but not in HTML files that link to them.

Im fact, if you zoom out all the way, you'll see that we're actually looking at a sphere from the outside, as if the stars are situated on a celestial globe. It seems to be a relatively common convention for interactive night-sky maps.
If I were betting, I'd bet many of the supposed bugs are readers working around incorrectly-implemented servers. If the feed doesn't update, but it's because of a server bug, your users are still left unhappy. In a perfect world the readers would note which servers are implemented correctly and which you can't trust last-updated / etags etc... that's a lot of work.

I’m glad you wrote this. I have one of these, and I love it, but haven’t ridden it in the rain. Now I won’t. I thought it might be okay because, as you pointed out, it definitely wasn’t cheap.
looking at these comments, it seems perfectionism is ill-defined.

it seems to be positive - perfectionism is not giving up, it is excellence, it is beyond mediocre.

it also seems to be negative - it is going too far, it is avoiding/procrastinating, it is self-defeating.

I wonder what the perfect definition would be?
Bulk Unsubscribe: Unsubscribe from marketing/promotional emails in one click
Absolutely, but in this case it was a go around from a non precision approach due to weather, according to Avherald.
I'm not. I'm asking why this flow is "distribution":

* User types an address into Perplexity

* Perplexity fetches the page, transforms it, and renders some part of it for the user

But this flow is not:

* User types an address into Orion Browser

* Orion Browser fetches the page, transforms it, and renders some part of it for the user

Regardless of the legal question (which I'm also skeptical of), I'm especially unconvinced that there's a moral distinction between a web service that transforms copyrighted works in an ad hoc manner upon a user's specific request and renders them for that specific user vs an installed application that does exactly the same thing.
Hey HN.

I've been sitting on this post for a while, finally deciding to share it without a hosted version. You can check out the github repo too: https://github.com/danthegoodman1/BulkUnsubscribe

Despite waiting so long and not offering a hosted version, I'm really proud of this project both from a full-stack completion perspective, as well as cutting through Google's monumental mountain range of dogshit.
At planetary scale it seems to be quite important not having to replace the whole fleet every few years don‘t you think? Just from a resource perspective this planet shouldn‘t drown in defunct solar panels.
> How did the Voyagers avoid hitting asteroids when exiting the solar system? I thought there was a huge cloud of asteroids surrounding our solar system.

The same way the Saturn probes went right through the rings and didn't hit anything.

Even if it looks like a "cloud" or "ring", that doesn't mean that it is "dense". There are whopping distances between objects in space.

It is way, way, way more difficult to actually "hit" something in space than it is to avoid something.
Is good code never altered or extended? Can good code serve as a learning tool? Can good code explain a complicated process in precise detail?

Considering how hard it is to get statistics right in sanitized laboratory settings, I've always expected most statisticians in private companies to be generating more noise than signal. A lot of people (anecdotal I know) complain that these jobs often come down to 'give the deciders confirmation for their choices'.

This blog post seems to articulate my misgivings better than I ever could. She does conflate APIs and libraries tho which is an unfortunate conceptual mistake when calling out software developers for having poor mental models of their tools.
Go isn't pretty to look at, but I feel so much more confident in a successful Go build than starting up Python–not knowing when exceptions will throw or crash until it's run is frustrating.

I'm sure Rust folks feel exponentially more safety than Go at compile time, but the jump from Python to Go is dramatic for me.
But was it boeing or airbus???
I'm very curious what the state of specifications has been. Saying clients can do whatever encryption they want doesn't help anything, in my view. Something based around group communication standards like Message Layer Security would be good. But even that leaves a ton of implementation details & exchanges up to implementers.

It's really a pity GSMA has such a strong hold on this industry. It seems like there just aren't a lot of other forums for this kind of work. Or perhaps the forums are all, like GSMA pretty slow big business plodding institutions. Reading up on RSC Business Messaging (RBM) and why GSMA started doing this stuff; it quickly sours any illusion this was some noble effort. This is a way to start charging businesses more, it seems like, with fancy expensive differentiation. https://en.wikipedia.org/wiki/Rich_Communication_Services#RC...

On the web it's so amazing how many enthusiasts & craftsfolk are empowered have such great forums to propose & get help trying to create standards. W3c and whatwg and wicg and tc39 and ietf are models we don't see repeated often, nor do there seem to be that many other empowered agents of progress helping championing & pioneering.

Google has an end-to-end encryption capability, no? Did they try to specify or standardize that anywhere? What are the efforts in the field here?

Pretty funny that the railroads have also been trying for years to cut crew sizes to one. All this while building extremely long trains which require a lot more finesse to manage over complex terrain and in and out of railyards, many of which are not designed to accomodate trains of that length. Place all that responsibility on a single point of failure. Luckily the union was able to stifle that effort in their recent agreements.

There is a real danger when bean-counters with no practical experience run a company and look at every component, including the employees, as a cost center that can be trimmed as needed to tailor results for quarterly reports that guarantee that investors will remain engaged.
The fundamental energy responsible for the universe is consciousness, and the goal of consciousness is to create, to experience, to learn and to improve (or re-create), ultimately evolving to a state of lower entropy (creating order out of chaos). The pyramids on the ancient artifacts represent our consciousness. And if you take a look at the depictions of the pyramids with the eye (or sun) on top, you’ll notice that the top of the pyramid is always missing. This symbolizes the fact that the development of our consciousness is always ongoing and will likely never end — at least for as long as the universe exists. We’re on a continuous path of building our consciousness, brick by brick, slowly but surely reaching higher states of awareness.

And where are we ultimately heading? To the very top, of course; towards the sun; towards enlightenment. The ancient people used various objects in nature to symbolize certain concepts, and the sun above the pyramid represents enlightenment — the highest state of awareness, knowledge and wisdom. The idea behind this is that the bright light from the sun allows us to see our environment and when we can see our environment clearly — i.e. when we can see things as they truly are — we can start to collect valid information about it and build a good understanding of it. That’s why when you withhold knowledge from people it’s called “keeping them in the dark.” This is also why one of the well known secret societies called themselves the Illuminati; they considered themselves the illuminated ones, because they possessed knowledge others didn’t have; in other words, they were illuminated by the extra knowledge they possessed while everyone else was (relatively) in the dark.
Winter being a problem really depends on location. Seasonal variability is much lower near the equator. Also batteries are becoming a solved tech. Also wind is anti correlated with solar, it's stronger in winter and at night. So you want 50-50 to minimize the need for storage.
Good Models do not Match Variance
Fair points! I tried to clarify in my edit, but I was mostly speaking from the perspective of grid decarbonization, as opposed to more niche (to me) applications like space probes, because that is what my personal biases are towards. It seems like a few more percentage points of efficiency at the same cost/space (so ignoring something like perk pv) doesn’t meaningfully move the needle on decarbonization efforts any more and that other challenges dominate (grid infra, batteries, etc). And I actually mean “solved” in a celebratory manner - it’s awesome that we are at this point! But yes, I was totally overlooking use cases besides residential and grid-scale PV.
