very cool! at first it looks like a lot to avoid spending $20/month but I realize I am already using LM Studio, which has a language model browser in it and lets you hot swap them in, in a nice single click GUI. Most notably, it also lets you switch to server mode and accepts and serves requests in the OpenAI REST format, across my local network or simply my main machine on various ports.

so some privacy and multimodal is great. glad the pieces are getting more user friendly to casually use
Actually, quite a few algorithms can provably find global optima. However, there's a property of such algorithms that makes them (often, but not always) impractical for many problems.

Any algorithm which can find a global optimum must necessarily sample its input space densely. That means that to be sure that we have the global optimum, we must evaluate the function within every epsilon-ball in our input space. If we didn't, then we could construct a function which was the same as some function we had found the optimum for everywhere except for in a single epsilon-ball, and which had a lower value than the minimum value in that ball. Then, our algorithm wouldn't find this new minimum and thus would not be a true global optimizer.

This property means we can't really provably obtain global optima without prohibitive numbers of function evaluations. However, for most "normal" functions, these algorithms typically work quite well and are commonly used in derivative-free black-box optimization. One famous and easy-to-understand example is the DIRECT algorithm. The paper describing this algorithm is quite well-written and easy to read, and well worth your time if you're interested in global optimizers.

I disagree. While I appreciate the thinking, it’s not at all like wheelchair ramps. Supporting IE actively made life worse for everyone else. Resources are limited, so dragging that junk heap along meant that developer time was wasted on it instead of adding new features people wanted. Wheelchair ramps are useful for everyone at some time, even if it’s just helping someone push a cart a little more easily.

I see little evidence that they are a disavowed fringe group. I see alot of evidence that they're at the top, in control, and at least clever enough to dodge questions about their position on nuclear. That is, when they're not outright lying about it. It's not a new development, this was evident since at least the early 1990s.

> I guarantee you that if limitless, clean, cheap energy became the norm then the vast, vast majority of the world

But that's irrelevant. You speak as if "if this technology magically falls into our laps". Technology does not do that. It requires effort and money and time, and these people have done what they can to worm their way into positions where they're in charge of doling out those things.

There's another comment whining about how it would take at least "6" years to get moving with nuclear. This, to them, is an argument against. To me, it's an argument for even more hurry. If things take awhile to get moving, you don't put them off even longer.

Most people are so ignorant of all of this, that they exert absolutely no influence in one direction or the other. What they want will matter little in the end.

If Norway really wanted to invest into more energy production, then infusing more research money into tidal power would likely results in better returns than nuclear.

Sweden mostly need nuclear power in order to stop burning oil/biofuel. The southern part of Sweden regularly need more energy than get produce, and thus the oil plant located there need to operate at almost 24/7. It is the single largest source of pollution by a very large margin. A nuclear plant in that region would also help Denmark reduce their footprint when the weather is sub optimal for wind production. More wind energy is likely not going to cause much harm (except when placed onto nature reserves), but the issue with the oil plant is also not going to be solved by more wind energy. Denmark is already well over 100% wind capacity.
I received a degree in electrical and computer eng. In general, CS can get you in the door for industrial automation, particularly with the ability to write simple HTTP servers and a familiarity with networking for embedded products.

As far as "good enough training to find a good position" if you want an "engineer" job title, get a masters degree from an Accreditation Board of Engineering Technologies (ABET) program. You should be able to do this in two years part time study at a local state engineering school. All state engineering schools are approximately equal in this regard.
Wow, this feels like the one. Having port based communications feels like what's necessary for fabric mode. A robust trust/security model. 32 bits of user-defined metadata for addresses, allowing all kinds of fancy smart pointers stuff. P2p dma- between devices.

My favorite though is host-to-host memory access! We have all these systems connected via the most awesome high-speed dma system. Not having the hosts be able to communicate over it felt absurd. I was starting to think this was going to be a long dwelling complaint! Not bad seeing this addressed, 15 months after 3.0 was announced.

>Most people I know barely see their parents

Anecdotal, but I see my wife’s parents several times a year (500 miles away) and video call with them daily, sometimes multiple times a day.

I still talk to my parents, but not as much. I think the reason for this is that I feel like her parents have more in common with me and are friendlier and open to different things. Not to mention showing an interest in minutiae of life.

I still love my parents of course, but they also don’t put the same amount of effort that the wife’s do. My Dad was pretty mean when I was growing up, and isn’t anymore but I know he regrets being the way he was.

Coincidentally, my wife and I are expecting our first child spring next year. For us, it’s hard to answer “why”. I guess it’s a feeling of wanting that deep unique love, for having a deeper purpose.

The public behavior of their CEO makes me very skeptical of their public claims about this OS.

The CEO has tons of tweets along the lines of (not really exaggerating) "my OS is perfect and cannot be hacked. I have XYZ certification. I used to work on nukes."

Objective-C++ was created to enable the creation of the Lotus Improv spreadsheet. The underlying spreadsheet engine was developed in C++ and bridging bidirectional via C to Objective-C for the UI was judged to be too inconvenient, and the developer tools folks at NeXT realized the C++ and Objective-C grammars were easily reconcilable so they put them together to allow mixing at the statement level. It worked great!

In my country there is a fairly common expression "det sitter i ryggmärgen" literally "it's in the spinal cord" which means that you have practiced something a whole lot and know it by heart. The implication being that the spinal cord can do the task on its own without involving the brain. It's so common that it wouldn't surprise me if 1st grade teachers used it without even reflecting on the literal meaning.

Now whether the spinal cord actually can learn motor skills seems to be a bit of an open question, but it can perform some instinctive tasks like shying away from painful stimuli.

> Your statement that matter has average uniform density in all directions around us is obviously only correct in sufficiently large frames of reference

Yes, agreed. But the distance to our cosmological horizon is large enough that the averaging assumption is fine on that scale.

> You should expand on why the cosmological horizon does not function in the same way the GP's "event horizon" analogue does

Fair enough. But first I'll reference an excellent paper by Davis & Lineweaver (2003) [1]. You can find much more detail there than I'm going to give here.

Some simple facts about our cosmological horizon are:

(1) It is currently receding from us very slowly (in terms of proper distance); and asymptotically it will be at a constant distance from us forever (in more technical language, our universe approaches de Sitter spacetime asymptotically, as all other matter and energy becomes negligible compared to dark energy; and in de Sitter spacetime the cosmological horizon is at a constant distance forever). It certainly is not receding from us at the speed of light.

(It is true that the horizon is a lightlike surface--but that does not mean it's receding from us at the speed of light. In fact, counterintuitively, to the extent it is "moving", locally, in any direction, that direction is towards us, not away from us! But due to the curvature of spacetime, its proper distance from us will asymptotically be constant.)

(2) It is not a boundary between things that can affect us gravitationally and things that can't. To the extent there is such a boundary in GR, it's our past light cone (which is shown in the diagrams in Figure 1 of the paper I referenced). But one also has to consider the other caveats I gave in my earlier post.

(3) The cosmological horizon is a boundary in spacetime, not space. It is a boundary between the region of spacetime that will be able to causally affect us into the infinite future, and the region that won't. Particular objects, as they recede from us, will move beyond the cosmological horizon and will then no longer be able to causally affect us. But events that occurred in those objects before they moved beyond the horizon will still be able to causally affect us--though of course it will take time for those effects to propagate to us. For example, the light we see from distant objects is a causal effect, but we see the objects not as they are "now" but as they were when the light was emitted. It's quite possible for a distant galaxy whose light we are seeing now to be beyond our event horizon "now", but they weren't when they emitted the light.

The spacetime diagrams in Figure 1 of the paper I referenced can be very helpful in making all this clearer.

> expand on how large the frame would have to be to achieve reasonable uniformity.

A few billion light years is certainly large enough. Our cosmological horizon is quite a bit further away than that (about 16 billion light years, according to the paper I referenced).

Ask HN: What happens if I don't abide by GDPR and put a banner on my website?
I've noticed that Hacker News and Reddit don't make me click on a banner each time I visit. Neither do Facebook, nor X.

On the other hand, many, many websites do show me an obnoxious banner that I have to acknowledge every time.

Why did they decide to put it up? Does it matter if they aren't an EU based website? What is the consequence of not putting up the banner / pop-up? Has anyone been taken to court for violating GDPR because they didn't put tell their users that they'd be serving up cookies?
This is just the tip of the iceberg. LLMs are generating text, acting as assistants, and some of the things they say have impact in the real world. This loops back in the next iteration of web data.

Besides immediate answers in the chat window, AI already has a slow feedback loop, it can explore and probe through humans. Even if we don't do anything to provide a way (embodiment) for AI to explore it can do it as long as we rely on its services as assistant.

The most obvious is writing code with GPT-4 and reporting errors to get updated codes. The model gets valuable feedback about its errors this way, possibly also hints from the user. There is a big difference between imitating human code and debugging your code logic.

So the way I see it: large language models place text into society, and society loops back text and feedback. It's a data cycle. Content after December 2022 seems particularly useful for further advancing AI. The garbage-in-garbage-out scenario doesn't apply because everything is filtered through humans and the real world.
> Is there a lower Planck-like limit?

Only in speculations that we have no way to test now or in the foreseeable future. We are many, many orders of magnitude away from being able to probe spacetime on such scales.
Not everybody is an activist or trades in outrage, and the fact that this is so is a good thing. That’s one reason Twitter remains so popular: the vast majority of people don’t live their lives as a constant orgy of boycotts whereby they deprive people they dislike or find odious or disagree with of their patronage, if that patronage brings convenience and if the user/customer can largely ignore the odiousness (whatever it might be) while deriving the benefits. Most people just ignore Musk altogether while having no related problems using a product he happens to own.

The author, who seems outraged that most others don’t share his outrage (at least in actionable degree) about Musk’s antics, might start clearing up some of his confusions there.

The majority of people find activists obnoxious and annoying and hate them:

(*YMMV*)

For some of you suffering for tinnitus, if you came here looking for a hack, I can offer a small tinnitus hack that worked for me, and may work for you if you find a noise that "cuts" the tinnitus sound. This summarizes what worked for me:

I have bilateral tinnitus that sounds like people screaming in each ear at 15.5khz -- it's bad enough that w/o this hack, self-harm would seem like an attractive option, which was incentive enough to get creative and now I'm only in pain a few minutes/day.

I'm on mobile so please forgive the AI assisted rewrite of a different post I made on HN [1]:

I hope this message reaches those struggling with tinnitus. I understand the intensity of the condition – my own tinnitus was unbearable. But I've found an effective way to manage it, and I'd like to share the steps:

1. *Effective Sound Track*: First, use YouTube-dl to download a specific sound track from this link: [Sound Link](https://youtu.be/8indTo2ykPw?si=izyTOg4gYvnfsqZs). I found it incredibly effective for cutting out tinnitus. It’s worth trying different sound prints if this one doesn’t work for you. Others with tinnitus have also found it helpful. You might want to edit out the initial dialogue using Audacity.

2. *Special Headphones*: Buy waterproof bone conduction headphones that are specifically designed for MP3 playback. Here's the link to the ones I use: [Headphones Link](https://a.co/d/aqqhPm9).

3. *Usage*: Load the MP3 onto these headphones. It’s been a life-changer for me, allowing me to experience what a normal life feels like again. I only really notice my tinnitus briefly each day when I wake up, before I sleep, and when I charge the headphones.

(end AI assist)

The reason this works (for me) is because I hear the tinnitus "inside my head" and the bone conduction headphones similarly make the noise print sound as if it originates from "inside your head". It does not interfere with normal hearing and you quickly become accustomed to the noise print and forget you even have it on your head. This particular model is NOT bluetooth-- it is an appliance that has one function only, play the scrubber noise. This reduces anxiety of dings and beeps and untethers your from your phone, and most of you know anxiety makes it worse. You can also wear these in the bath and the shower.

I'm sure it won't work for everyone, but it's been a literal lifesaver for me, so I hope it helps.

Good luck out there.

This sort of criticism gets repeated all the time ("Google designs for Google scale, but you're not Google, so don't use kubernetes!"), and sometimes it's fair, but this doesn't really make sense to me on this particular article.

If the infrastructure exists within your org's distribution of choice to do this, it's basically all upside. On AL2023, you just do:

`sudo dnf install -y kpatch-dnf kpatch-runtime`

`sudo dnf kernel-livepatch -y auto`

`sudo systemctl enable --now kpatch.service`

You can develop a sense for GPT-4, or DALL·E 3 fine, how about GPT-6 or DALL·E 5?

Yet, now I start to understand what they must have felt like. I can about keep up for now, but how about in 5 or 10 years from now? I don't feel so confident.

> this matter distribution has to be perfectly balanced for its gravity to cancel out to zero at some point?

In principle, there are of course effects due to the matter distribution not being perfectly spherically symmetric about us. But except for the obvious effects that are due to nearby obvious objects--like the Earth, the Sun, our galaxy--in practice the gravitational effects of the rest of the universe on us are negligible.
