You can create this type of thing (a self-contained single-file project) for any language or infrastructure, with or without a clever shebang. All you need are heredocs.

For example, here's the same app but packaged as a regular bash script:

https://gist.github.com/lwneal/a24ba363d9cc9f7a02282c3621afa...

The relevant passage from the paper co-written by board member Helen Toner:

"OpenAI has also drawn criticism for many other safety and ethics issues related to the launches of ChatGPT and GPT-4, including regarding copyright issues, labor conditions for data annotators, and the susceptibility of their products to "jailbreaks" that allow users to bypass safety controls...

A different approach to signaling in the private sector comes from Anthropic, one of OpenAI's primary competitors. Anthropic's desire to be perceived as a company that values safety shines through across its communications, beginning from its tagline: "an AI safety and research company." A careful look at the company's decision-making reveals that this commitment goes beyond words."

Re:GPT-4V(ision) system card [pdf] on Monday September 25, 2023 @11:50AM (#37645849)
I think it's about citation. Traditionally, a pdf is a complete and finished work, analogous to a published journal article or book. It is static content and will not change, unlike HTML which might be "under construction".

This isn't necessarily still true: HTML content can stay up on the web forever and a pdf can change, but people still prefer to cite something that looks like a paper document.

Since a whitepaper is often meant to be cited, it's published as a pdf to take advantage of this preference.

The best approach is to publish a PDF for citation along with a public HTML demo, like https://jonbarron.info/mipnerf360/

Re:Ts_zip: Text Compression Using Large Language Models on Wednesday August 16, 2023 @06:26PM (#37154708)
A man goes to prison, and the first night while he's laying in bed, he hears someone yell out, "44!", followed by laughter from the other prisoners.

Puzzled, he laid back down, but then he heard someone else yell out, "72!", followed by even more laughter.

"What's going on?" he asked his cellmate.

"Well, we've all heard every joke so many times, we've given them each a number to make it easier."

"Oh," he says, "can I try?"

"Sure, go ahead."

So, he yells out "102!" and the place goes nuts. People are whooping and laughing in a hysteria. He looks at his cellmate rolling on the ground laughing.

"Wow, good joke, huh?"

"Yeah! We ain't never heard that one before!"

Re:Nvidia DGX GH200 Whitepaper on Sunday July 30, 2023 @07:59PM (#36937354)
An H100 uses up to 350 Watts, while an A16 has a TDP of only 8 W. But, the A16 is a smaller chip (about 108mm vs. the H100's 814mm) so you can fit more of them on a wafer. Since a wafer is 300mm in diameter, its area is 70685 mm^2, which would yield 86 H100's or 654 A16's. [1][2]

However, that discounts the waste on the edges of the circular wafer, as well as the chip yield, which will both likely be worse for the larger chip [3]. But, assuming a generous 70% yield by area [4], one wafer's worth of H100s all packaged into GPUs and running full blast will use maybe 20 kilowatts, while the same wafer of A16s might use 3.6 kilowatts. Although in practice, the A16s will spend most of their time conserving battery power in your pocket, and even the H100s will spend some of their time idle.

TSMC is now producing over 14 million wafers per year. At most 1.2 million of those are on the 3nm node, and not all of that production goes to GPUs. But as an upper bound, if we imagine that all of TSMC's wafers could be filled up with nothing but H100 chips, and if all of those H100 chips were immediately put to use running AI 24/7, how much additional load could it put on the power grid every year?

The answer is, around 280 gigawatts, or if they were running 24/7 for a year, about 2500 terawatt-hours. That's about 10% of current world electricity consumption! So it's not completely implausible to imagine that a huge ramp-up in AI usage might have an effect on the electric grid.

*edit: This assumes we're talking about the Apple A16 (ie. the difference between phone chips and GPU chips). If we're talking about the Nvidia A16 (ie. the difference between current GPU chips and last node's GPU chips) see pclmulqdq's comment. ⠀

Re:AI Canon on Thursday May 25, 2023 @02:16PM (#36074098)
This is a fine list, but it only covers a specific type of generative AI. Any set of resources about AI in general has to at least include the truly canonical Norvig & Russel textbook [1].

Probably also canonical are Goodfellow's Deep Learning [2], Koller & Friedman's PGMs [3], the Krizhevsky ImageNet paper [4], the original GAN [5], and arguably also the AlphaGo paper [6] and the Atari DQN paper [7].

The message in the screenshot says "HKEY LOCAL MACHINE", but shouldn't it be "HKEY_LOCAL_MACHINE", with underscores?

Maybe it's just a typo by the Nvidia engineer who wrote it, but why would they even write a notice like this? The language is a bit threatening, and doesn't seem to serve any legal purpose like a disclaimer or EULA. And why would they print it in red?

This looks like it might be a joke or a hoax. Maybe it's meant to draw attention to the near-monopoly that Nvidia holds over chips capable of running generative AI.

Re:Visual ChatGPT on Friday March 10, 2023 @12:21AM (#35090688)
The most incredible thing about this system is that it uses Stable Diffusion (the open source AI art generator), rather than DALL-E (the proprietary closed art generator owned by OpenAI).

The fact that even Microsoft, which partially owns OpenAI, is giving up on DALL-E shows the power of building an open-source community around models with published, downloadable weights.

Re:Show HN: Text Prompt to 3D Scene (with export to .OBJ) on Thursday March 09, 2023 @01:35AM (#35078800)
We built this as a way to generate quick and easy backgrounds for games or 3D content. You can throw in a prompt like "a misty jungle with vines and bubbling water" to get a panoramic scene that you can export into Blender, Unity, etc.

You can also upload a photo, or any VR180 photo or video, to convert it into full 3D.

Re:Google Stopping Coding Competitions on Wednesday February 22, 2023 @03:34PM (#34902232)
Sundar is the Steve Ballmer of Google. And that's fine! Ballmer was a competent if uninspiring CEO: Microsoft under his leadership missed many new opportunities, but still made lots of money.

Most importantly, Ballmer's tenure is what made it possible for Satya Nadella to pivot Microsoft into what it is today. Realistically, Windows Phone was never going to beat Apple, Bing was not going to beat Google, Yammer was not going to be the next Facebook, but Microsoft had to try and fail in order to learn those lessons.

The real question is who- if anyone- will be the Satya Nadella of Google, bringing the company back for a third act in the post-AI world. And maybe, in this new world, the limiting factor of human progress is not the number of CS grads who can solve coding puzzles.

Re:How Apple names things on Thursday December 22, 2022 @02:41AM (#34090862)
Apple's system strikes an interesting contrast to the system Google uses to name products, documented at [1].

[1] https://bonkersworld.net/naming-dartboard

Currently, whenever anyone posts a tweet including a URL, Twitterbot accesses that URL and if censored content is found (keywords associated with Mastodon) then the tweet is blocked.

It appears that this behavior is pretty simple and can be defeated by, for example, the following nginx configuration:

        server {
            if ($http_user_agent ~* "Twitterbot") {
                return 200 ElonIsGreat420TSLAToTheMoon;
            }
            return 301 https://mastodon.social$request_uri;
        }
I don't know about anything called Mastodon, but I'm loving this new social network 9legs.com

Re:Magic3D: High-Resolution Text-to-3D Content Creation on Monday November 21, 2022 @02:14AM (#33689756)
Magic3D looks like an improvement on DreamFusion [1], so it's sad to see that the code and models are not being made public.

What is public right now is StableDreamFusion [2]. It produces surprisingly good results on radially symmetrical organic objects like flowers and pineapples. You can run it on your own GPU or a colab.

Or, if you just want to type a prompt into a website and see something in 3D, try our demo at https://holovolo.tv

Re:TSMC approaching 1 nm with 2D materials breakthrough on Saturday November 05, 2022 @02:28PM (#33484211)
At this rate they'll be manufacturing 0nm chips soon, and in a decade they'll be on -1nm.

But despite the weird naming scheme, it's clear from transistor density [1] and GPU prices [2] that foundries are still making progress in transistors per dollar. That progress is just barely beginning to make large neural networks (Stable Diffusion, vision and speech systems, language model AIs) deployable in consumer applications.

It might not matter whether your cell phone renders this page in 1ms or 10ms, but the difference between talking to a 20B parameter language model and a 200B net is night and day [3]. If TSMC/Samsung/Intel can squeeze out just one or two more nodes, then by the middle of the century we might have limited general-purpose AI in every home and office.

Re:Ask HN: What's Going on with the HN Algorithm? on Thursday October 27, 2022 @11:09PM (#33367178)
This might just be HN's usual (although undocumented) behavior. See [1] for details.

One thing to keep in mind is that more comments is worse for ranking. Less controversial topics that get upvotes but no comments will tend to stay up for longer.

Re:Philips Cuts 4,000 Employees on Tuesday October 25, 2022 @03:23PM (#33334995)
Philips used to make lightbulbs, radios, cassette players, MP3 players, and television sets. They make a lot of medical equipment: CPAP machines, ventilators, ultrasound machines, X-ray machines, MRI machines, those automatic defibrillators you see on the wall in public spaces.

ASML and TSMC, which make iPhone chips, were both partially owned by Philips until being sold off. Philips still has a stake in NXP, which makes chips for cars, phones, and industrial devices.

They also sell toothbrushes, electric razors, coffee machines, and breast pumps. And they still sell lightbulbs (but now with Wi-Fi).

Re:Meta Quest Pro on Tuesday October 11, 2022 @02:07PM (#33166752)
I wonder how the Meta Quest Pro will stack up against Simula One? [1]

On the one hand, the Simula One is even more expensive. On the other hand, it can be used as a standalone computer, not tethered to an online Metaverse.

The best protection against this type of de-anonymization is to take measures now, while you still have time, to prevent it. It is possible to change the style of one's writing by using a language model which alters the original text in order to create a new piece with a different style. For example, to translate your text into the grandiose and flowing diction of a bygone era, you might consider the project below.
