I think you've missed the point here: the noise in the originals acts as dithering, and increases the resolution of the original video. This is similar to the noise introduced intentionally in astronomy[1] and in signal processing[2].

Smoothing the noise out doesn't make use of that additional resolution, unless the smoothing happens over the time axis as well.

Perfectly replicating the noise doesn't help in this situation.

Just to add to this, from a former colleague of mine who currently works as a graphics programmer at a UE5 studio: most graphics programmers are essentially tech support for artists nowadays. In an age where much of AAA is about making the biggest, most cinematic, most beautiful game, your artists and game content designers are the center of your production pipeline.

It used to be that the technology tended to drive the art. Nowadays the art drives the tech. We only need to look at all the advertised features of UE5 to see that. Nanite allows artists to spend less time tweaking LODs and optimizing meshes as well as flattening the cost of small triangle rendering. Lumen gives us realtime global illumination everywhere so artists don’t have to spend a million hours baking multiple light maps. Megalights lifts restrictions on the number of dynamic lights and shadows a lighting artist can place in the scene. The new Nanite foliage shown off in the Witcher 4 allows foliage artists to go ham with modeling their trees

Reading the chat logs in the article is an eye-opener. It's one thing to say "yeah this chatbot sounds smart", it's another to have the chatbot literally telling you it's sentient and able to make its own decisions. Obviously this man had been subconsciously conditioning the model to respond that way by asking it leading questions, but I can totally see why he would be affected by this.

> The US doesn't really have an attractive answer to getting to the moon or for aggressive deep space missions, Starship doesn't look great.

Starship is almost an assisted single stage to orbit (ASSTO), the first stage gives rather modest part of total characteristic velocity.

This allows the second stage, Starship, to have a lot of delta-v. I guess it was optimized for Mars operations. Yes, Starship requires refueling for any flight away from Earth orbit, but in exchange for that it packs significant delta-v, so sending large payloads away from Earth - after refueling - becomes easier. That includes Mars, Moon, asteroids, the rest of the Solar system.

I think this makes Starship design rather good.

Well, we can split up the credential into multiple ones sharing a serial number to fix the array signing. To bind to NIST there are some solutions based on ZkAttest (which got fixed, I made a few mistakes in it) to show signature under ECDSA while hiding it.

I disagree that no one is talking about it: the solutions are there, it is a question of getting the resources to put it together. Circuit based solutions have some nice properties, but the actual security assumptions are a bit odd, and the reasons people should trust a complex circuit and verification protocol are a bit hard.

I don't however think this is really the big debate. Rather it's about ensuring SD-JWT and related non-private solutions do not get used. To the extent that this work helps show it's possible, and the tradeoffs are desirable, it's good.

Nextest works on a variety of platforms and architectures -- a lot more than x86_64 Windows and Linux. Porting to new platforms tends to be quite straightforward as long as someone's made Tokio work on that platform. (This is the power of abstraction! Turning MxN portability problems into M+N ones.)

C definitely has a place, but "Rust is not portable at all compared with C code" is simply not correct. A lot more Rust code works across Windows and Unix than C code does. Rust's portability story is different from C's, much better in many ways but worse in others. In practice I do think Rust ends up being more portable than C in most practical scenarios -- for example, look at how things like `eza` work on Windows, the number one developer platform worldwide.

Well an analogy would be like learning a second language…

In order, my ability to understand Spanish (ie I am close to B1 proficiency)

1. Reading Spanish

2. Typing Spanish (with autocorrect)

3. Speaking Spanish

4. Understanding spoken Spanish at normal speed (horrible at it).

Just because (the royal) you can read the code that ChatGPT creates, doesn’t mean that you can write the code (#2), talk intelligently about the code (#3) or understand the concepts when used in a large codebase (#4).

You want to prove to everyone that you know where the Waldo on Page 12 of Where's Waldo In Iceland, so you hold a big white sheet of paper with a hole in it in front of the page such that the hole is centered on Waldo. Then you let your friend see. Your friend now knows that you know where Waldo is, but they still don't know where Waldo is, because they don't know the relative position of the book under the sheet. This is also why they can't use your proof to falsely prove to anyone else that they know where Waldo is too.

My knowledge is out of date (I was in a microbiology PhD program starting in the early 2010s), but at that time, it was known that there are a whole lot out of micro-organisms out there, but many of them were probably difficult to grow as isolates in pure culture for a whole host of reasons. What people ended up doing is sequencing a ton of DNA from environmental isolates, and trying to assemble whole genomes from the 100-200 base pair sequenced DNA fragments that you would get out of a sequencer (which is challenging for a whole host of other reasons). Then, if you believed in the genome assemblies you got out of that process, you could compare those inferred genomes to known genomes, see how similar they are, guess at the metabolic pathways those organisms might possess, etc.

Not sure what the state of the field is now, and I don't really know too many specifics, because I never ended up studying too much in the way of microbial ecology. If you wanted to sequence a bunch of DNA out of environmental samples (pond water or something), you would probably search on google scholar for environmental DNA isolation to see what kind of kits people are using, and then you would probably get an Oxford Nanopore minION, make a sequencing library out of the extracted environmental DNA using their ligation sequencing kit, and then run that library on as many flow cells as you can afford (each flow cell costs ~$1000, and you sequence a library on each flow cell for 3 days to get as much sequencing data as you can). Oxford Nanopore presents a relatively low barrier to entry in comparison to the high-throughput sequencers used in academic, clinical, and Pharma settings, and it gives you sequencing reads potentially as long as the physical DNA fragments present in your sample, but it has a lower sequencing throughput in comparison to the big short-read sequencers. For this kind of metagenomic discovery work, you want as high a sequencing depth as possible, because an unknown organism might be at a low abundance in your sample compared to well-studied, common organisms, so you need more sequencing data to detect it.

Then you would run some genome assembly software (https://www.metagenomics.wiki/tools/assembly), and then look into comparing your assembled genomes to known environmental isolates, and annotate those genomes to get a sense of which enzymes are encoded by genes in the genome. That all sounds straightforward, but there are probably tons of different possible computational tools to consider.

This is what the guidelines mean by "generic tangent", "shallow dismissal" and being "curmudgeonly". The comment is not about the project or topic, it's just a general expression of discontent with things related to the project, without any consideration of whether that pattern applies to this project or whether this project may in fact be an exception to the pattern.

I'd say just give me a volume knob but there's almost nothing worth listening to on the radio anyway. I actually yanked the fuse on mine to keep it from draining the battery.

At least with climate controls give me tactile knobs. Of course someone I know got the new tachoma and they made the 4wd switch exactly the same as the AC/fan knobs which is just so fucking insane. It's like whatever process is used to design these interfaces seeks out the worst way to do it given the requirements.

Idk maybe I just want a dune buggy at this point. At least there's no design by committee corporate brain damage I can't rip out of that.

I don't like this theme. I don't like pushing people to use settings like "reduce transparency" because they also make the UI much uglier, even before this increase in the use of transparency-- non-default settings like this are an afterthought, design-wise. It means downgrading to a second-class experience.

However, I find this a bit irksome:

> The majority of people with vision impairments aren't people who are used to thinking of themselves as disabled and know their way around an a11y menu

That should change, and to the extent that something like this makes a small push in that direction, so much the better. Disability is a spectrum, everyone will deal with disability to some extent in their lifetime, and accessibility features are for everyone.

Separating out "serious" accessibility considerations from those of people with "normal" accessibility needs is just likely to make accessibility features even more second-class. If the main problem is the problem you describe, it should be fixed by better surfacing the existing accessibility features.

Actually I meant blockchain qua blockchain, that is, ledger and consensus. There is no ledger and consensus at all in this system.

If people want to redefine blockchain to mean zero-knowledge, and they want to redefine zero-knowledge to mean succinct as they all seem to have done, it's not my problem.

There is no blockchain here, period.

I remember years ago when digital projection was just becoming the norm. I saw a movie (I don't remember which one) and during the opening scene I remember thinking "why are the credits jittering around? Oh. This is actually being projected on film!"

I'm in my early 50s so I remember film quite well. Just like vinyl or cassettes, I ain't going back and unless it is an artistic choice I don't want films to emulate what I consider to be an inferior technology.

Neutrality is implicit support for whoever can muster the most power, neutrality is in many ways the opposite of law and betrays an ideology where there is no objective truth. When there is no objective truth, there is nothing to be curious about. When authortarians tell you what the truth is or rob you of the data to make your own assessments, curiosity becomes an act of rebellion.

I don't think HN mods operate as conservative or liberal (although curiosity is an extremely liberal cause), but I think they will come to understand the cost of neutrality.

If anything I think they have not fully confronted the paradox of intolerance or realized that the times are different than they were in the last 30 years of internet flame wars. In the past when Godwin's law and flame wars were the rule of every forum, there weren't historians at prestigious universities who studied the holocaust/fascism warning us that fascism is happening here in America right now.

When I met you at Stripe you seemed to me the person with strategic foresight and iron discipline— the kind that gets endless opportunities without even trying. I was hopelessly floundering by comparison, and not in a good Kevin Kelly way. I don’t know if people will think of you in 300 years (the day is young!) but you were definitely a role model for what discipline and great execution look like.

I have had this idea about parking a car...

Most people have proprioception - you know where the parts of your body are without looking. Close your eyes and you intuitively know where your hands and fingers are.

When parking a car, it helps to sort of sit in the drivers seat and look around the car. Turn your neck and look past the back seat where your rear tire would be. sense the edges of the car.

I think if you sort of develop this a bit you might "feel" where your car is intuitively when pulling into a parking space or parallel parking. (car-prioception?)

(but use your mirrors and backup camera anyway)

I suppose you are right, but we may not say "it has been widely known". Lots of us who read HN come from the the software side and we coders often hand wave on these topics when shooting the breeze -- much like how a casual car enthusiast might not imagine it was possible for a 6-cylinder engine to have more more horsepower than a V8.

Thank for you for this thoughtful reply!

Yeah, I definitely hear you with regard to the "greater fantasy" aspect. Some other players have also recently mentioned their desire for more fleshed out lore. It's something I personally struggle with but I should definitely do better in this regard, as I do want mochia to be enjoyed by more people.

You currently can feed your pets, give them toys, and read books to them (each book also has unique text that you can read inside, often with secrets about the world), and your pets should reply with their reaction (as different pet species like different things), but I agree with you that a lot of these interactions don't really "sell" themselves, and they certainly deserve more polish.

And yes, the minigames don't require an account. My apologies, I should have been more clear in the original post on exactly what a minigame is in this context. These are the locations that start off with a black tutorial screen, and then generally involve a game loop. Most other locations require an account because they require making a request to the server, but minigames can just be played entirely client-side just for fun. Here's some of my favorite ones that don't require a login:

In this case yes, because clearly if the goal is accessibility, then a company shouldn't face legal action unless they refuse when asked. Like in the DOJ examples in this comment section.

Any and every good cause will attract a bunch of vultures, scammers and scavengers, including accessibility issues. But I'm not going to believe those who say that any company which isn't up to date on this will "get sued to oblivion". Not without examples that prove it.

With that said, I'm a strong supporter of Internet accessibility because there are no down-sides to it. It is essential to the people who need it, and at the same time it improves the experience of those who don't.

To be fair, there was a pretty dumb CVE (which had already been found and fixed by the time the project made the rounds on HN):

https://github.com/cloudflare/workers-oauth-provider/securit...

You can certainly make the argument that this demonstrates risks of AI.

But I kind of feel like the same bug could very easily have been made by a human coder too, and this is why we have code reviews and security reviews. This exact bug was actually on my list of things to check for in review, I even feel like I remember checking for it, and yet, evidently, I did not, which is pretty embarrassing for me.

The real world moves. If your code didn't change it must be generating value against something that is very standard but I'd be very surprised that you're not modifying, adding, etc based on usage to derive even more value somehow.

> Code that doesn't need to change is a really good sign that you've got something good.

Not really, but you're thinking in terms of "my code nailed it because I'm not touching it" and that has NOTHING to do with it being easy to change.

I like thinking about the ISS as primarily engineering (and operational) experiments rather than hard science. As a space platform, it's provided learning on how to contract private companies for space flights, and in turn, how they should operate, plan, etc. Or how to do internationally coordinated space operations. All of the work it takes to mature a new tech to a 7,8, or 9 on the NASA Technology Readiness Level[0] while Curiosity and Ingenuity and other long-distance (and JPL) missions focus on the hard science of 1's and 2's.

That said, I too think the main value of ISS declined several years ago or more. Looking forward to the next generation, whatever it is

Abstract

African heritage diets are increasingly being replaced by Western-style dietary patterns because of urbanization, economic development, increased access to processed foods, globalization and changing social norms. The health consequences of this nutrition transition are not well understood. We conducted a randomized controlled trial in the Kilimanjaro region in Northern Tanzania to investigate the immune and metabolic effects of switching between Kilimanjaro heritage-style and Western-style diets for 2 weeks and consuming a traditional fermented banana beverage (‘Mbege’) for 1 week. Seventy-seven young and healthy volunteers assigned male at birth, some living in urban areas and some living in rural areas, were recruited in the trial. Primary outcomes were changes in the immune and metabolic profile before and after the intervention and at the 4-week follow-up. The switch from heritage-style to Western-style diet affected different metabolic pathways associated with noncommunicable diseases and promoted a pro-inflammatory state with impaired whole-blood cytokine responses to microbial stimulation. In contrast, the switch from Western-style to heritage-style diet or consuming the fermented beverage had a largely anti-inflammatory effect. Some of the observed changes in the immune and metabolic profiles persisted at the follow-up, suggesting a sustained impact from the short-term intervention. These findings show the metabolic and immune effects of dietary transitions and the consumption of fermented beverages, underscoring the importance of preserving indigenous dietary practices to mitigate noncommunicable disease risk factors in sub-Saharan Africa. ISRCTN trial registration: ISRCTN15619939.

Roger Ebert on Madsen’s breakout role in Reservoir Dogs:

> One of the discoveries in the movie is Madsen, who has done a lot of acting over the years (he had a good role in “The Natural“) but here emerges with the kind of really menacing screen presence only a few actors achieve; he can hold his own with the fearsome Tierney, and reminds me a little of a very mean Robert De Niro.
