thorum··on TikTok preparing for U.S. shut-off on Sunday
I don’t understand why, with so much advanced warning that users would need a good replacement for TikTok, YouTube Shorts and Instagram Reels are still so bad. Why not invest in matching, at least, every TikTok UX feature? And beyond that, how are these two leading AI companies really unable to make a recommendation algorithm that actually shows people things they like?
thorum··on TikTok preparing for U.S. shut-off on Sunday
Your perception of TikTok likely depends on your TikTok for you page. If you spend time cultivating it, the algorithm will learn you like authenticity and show you more of it.

This seems to be less true on YouTube and Reels unfortunately.

thorum··on The people fighting to get through to anti-science Americans
I agree in principle, but most people do not have the necessary education to make accurate judgments across all fields from first principle reasoning. Eg someone with a PhD in physics probably doesn’t have the knowledge to debunk every argument against the COVID vaccine. In those cases we naturally rely on asking some biologist who does have that knowledge what they think.
thorum··on The people fighting to get through to anti-science Americans
If public health experts are caught being deceptive in one case, or the media publishes as truth something that ends up being political propaganda- even once - they lose trust and people will correctly choose to treat future information from that source with skepticism.
thorum··on The people fighting to get through to anti-science Americans
As someone who cares deeply about science education, here are some hard truths that many people flinch away from:

“Anti-science” Americans are not less intelligent on average than “pro-science” Americans. It’s simply a difference of who they trust to give them the facts. One group trusts and believes the public health organizations; the other group treats those same organizations with extreme skepticism. No solution to this problem will be effective until trust in the system is rebuilt.

The core problem that no amount of trying to “get through” to people will solve is that America’s public health and science institutions actually are deeply problematic organizations that are politicized and do not always act honestly and in the best interest of the people. The media, meanwhile, has lost all trust with a significant segment of the population who rightly recognize it as a propaganda machine for the ruling elites.

Why should my parents, who are quite intelligent but never received any significant science education, believe what they are told about science by experts that they can clearly recognize as untrustworthy?

You have to recognize and address this before any progress can be made.

thorum··on My Favorite Book on AI
> The historian Yuval Noah Harari has argued that humans should figure out how to work together and establish trust before developing advanced AI. In theory, I agree. If I had a magic button that could slow this whole thing down for 30 or 40 years while humanity figures out trust and common goals, I might press it. But that button doesn’t exist. These technologies will be created regardless of what any individual or company does.

Is that true, though? Training runs for frontier models don’t happen without enormous resources and support. You don’t run one in your garage. It doesn’t happen unless people make it happen.

Is this really a harder coordination problem than, say, stopping climate change, which Gates does believe is worth trying?

thorum··on True crime stories are influencing the real-life justice system
Law enforcement is treated with more skepticism, and judges are more worried about being held to account for their decisions. It’s hard to see either of these developments as anything but positive.

The rise of amateur sleuthing is less clear. I can’t actually think of a single case where the true crime community actually solved a case that the police couldn’t. But you regularly see a mob of weirdos going after innocent people and trying to ruin their lives.

thorum··on Pornhub Is Now Blocked in Almost All of the U.S. South
Fair enough.
thorum··on Pornhub Is Now Blocked in Almost All of the U.S. South
This isn’t a counterargument. Yes, mainstream US sites are not saints and have many serious issues. Also yes, they are least subject to US jurisdiction and can be held to some account. If these restrictions drive users to websites that are far, far worse then they will be doing more harm than good.
thorum··on Arnis: Generate cities in Minecraft from OpenStreetMap
You’re right, and this is unfortunately becoming very common on GitHub, even for otherwise great projects.

Good technical writing is concise and tells you what you need to know as directly as possible. ChatGPT written documentation always reads like bad marketing copy.

thorum··on How Well Do LLMs Generate Code for Different Application Domains?
The goal is for the LLMs we have to be so good at long context tasks and reasoning about code that you can simply paste the entire documentation for your new language and they’ll figure it out.

Once you have that working, you can generate synthetic examples to train the next version of the LLM, or for open source coding models, a small LoRA file that anyone can download to add support to their model of choice.

thorum··on Does current AI represent a dead end?
Most of the comments here are responding to the title by discussing whether current AI represents intelligence at all, but worth noting that the author’s concerns all apply to human brains too. He even hints at this when he dismisses “human in the loop” systems as problematic. Humans are also unreliable and unverifiable and a security nightmare. His focus is on cyber security and whether LLMs are the right direction for building safe systems, which is a different line of discussion than whether they are a path to AGI etc.
thorum··on Trying out QvQ – Qwen's new visual reasoning model
Reasoning models are supposed to be able to work around that kind of limitation (o1 was code named strawberry after all) so it’s not a bad test IMO.
thorum··on Computing Inside an AI
The solution is user interfaces that are stable, but infinitely customizable by the user for their personal needs and preferences, rather than being fixed until a developer updates it.
thorum··on They see your photos
Reminds me of the article “Language Models Model Us”:

> “On a dataset of human-written essays, we find that gpt-3.5-turbo can accurately infer demographic information about the authors from just the essay text, and suspect it's inferring much more.

> Every time we sit down in front of an LLM like GPT-4, it starts with a blank slate. It knows nothing about who we are, other than what it knows about users in general. But with every word we type, we reveal more about ourselves -- our beliefs, our personality, our education level, even our gender. Just how clearly does the model see us by the end of the conversation, and why should that worry us?“

thorum··on Bankruptcy judge rejects sale of Infowars to The Onion
Thanks! The archived snapshot doesn’t have that, it must have been added later.
thorum··on Bankruptcy judge rejects sale of Infowars to The Onion
Am I missing something or does this NYT article not actually say what the judge based his decision on? That would be an important piece of information to have when deciding whether the decision was good or not.
thorum··on SQLite changed temp file prefix after McAfee users called devs to complain (2006)
Thanks for this, I was wondering why people would care so much about these files that they go and complain. Reading through these forum questions, looks like most people are trying to free up disk space by clearing temp files, but the SQLite ones can't be deleted - because they are in use and locked - which causes confusion.
thorum··on OpenAI Reinforcement Fine-Tuning Research Program
Clever way to get more training data.
thorum··on React 19
> I’m pretty sure it’s a cool feature but, what a mouthful. Imagine you decided to start developing websites today, how do you even start?

Easy: By not using that optional feature.

If you’re like 99% of developers you really don’t need stuff like that until your app reaches a certain stage of growth, if ever - and React doesn’t force it on you.

thorum··on The sham legacy of Richard Feynman [video]
This is a 2 1/2 hour video essay from Angela Collier, a YouTube physics educator, talking about the difference between the 'cult of personality' perception of Feynman vs the more complicated reality of who he actually was (the good and the bad).

I found it to be really insightful all the way through and well worth the time to watch for anyone with an interest in Feynman.

thorum··on Ask HN: What would you preserve if the internet were to go down tomorrow?
It’s pretty amazing that we’re almost at the point where a single laptop computer with no internet connection can contain (1) most of humanity’s recorded knowledge and (2) an intelligence that can explain it to you.
thorum··on Controllable Fast and Slow Thinking by Learning with Randomized Reasoning Traces
> We don't have a clue how to make a computer capable of System 1 thinking.

I think you’re overthinking this. System 1 thinking as the term is being used by AI researchers means making a fast decision based on reasoning processes that are wired into your brain by evolution. For any task that humans have faced for millions of years this works well. It can also work well for experts in a domain who have practiced a task so many times that their brains have adapted to perform it unconsciously.

System 2 thinking is consciously using explicit reasoning techniques to think through a problem, slowly and rigorously, often in ways that feel unnatural due to our cognitive biases but can solve problems that System 1 is unable to.

The analogy to LLMs is straightforward: LLMs learn to solve many kinds of complex problems during training and encode processes for those specific problems. They can then perform these tasks in a single forward pass through their weights. This is System 1 for LLMs and again, works well for any task that they were exposed to repeatedly during training.

However they don’t generalize to tasks that were not well represented in the training data. Training them to use explicit reasoning strategies instead (System 2) is shown to improve performance and let them solve a broader range of problems.

thorum··on Microsoft and OpenAI's close partnership shows signs of fraying
There seems to be an ongoing mass exodus of their best talent to Anthropic and other startups. Whatever their moat is, that has to catch up with them at some point.
thorum··on Update on Reflection-70B
CoT moderately improves model performance, but all non-o1 models suck at actually thinking step by step effectively. If the task is not straightforward, they make obvious mistakes or default to guessing.

OpenAI trained o1 to pick better steps in its chain of thought. (The moat is the dataset they used to do that.)

thorum··on Update on Reflection-70B
> This along with a few tokenizer related tests people ran, made people suspect that we are just serving Claude with post-processing where we filter out words like Claude.

Didn't these "few tokenizer related tests" prove the API was using Claude's tokenizer instead of Llama's, based on how words were being divided into tokens?

That's a hard one to explain (it doesn't appear they're even trying to).

thorum··on g1: Using Llama-3.1 70B on Groq to create o1-like reasoning chains
o1’s innovation is not Chain-of-Thought. It’s teaching the model to do CoT well (from massive amounts of human feedback) instead of just pretending to. You’ll never get o1 performance just from prompt engineering.
thorum··on The Threat to OpenAI
If the rumors about the upcoming Strawberry and Orion models from OpenAI are true - supposedly capable of deep research, reasoning and math - they probably don’t have much to worry about. Not to mention they still have the only fully multimodal model.
thorum··on Did you lose your AirPods?
Is 84 so high? I imagine there are people sending party invites and “lost my phone, new number” messages to more than that.
thorum··on Apple Wasn't Interested in AI Partnership with Meta Due to Privacy Concerns
It probably has more to do with reputation & appearances than with specific practices. Meta is well known for its bad practices regarding privacy, OpenAI is not (yet).
