flatline··on SpaceX stock erases all its gains and slides below IPO price in intraday trading
Every time there is an economic boom like this, you get unscrupulous actors coming in and extracting as much value as they can before the regulatory environment catches up. Yes, datacenters should be doing all these things, but that costs money, so they won't until there are local statutes and federal regulations that require them to do so. I expect the current situation to continue at a huge social cost for at least the next 5-10 years unless the bottom falls out of the AI boom before then.
flatline··on Prioritize mental health, and why communication is so important
Yeah I didn’t read it that way at all. I think that addressing mental health issues requires some frankness with yourself first and foremost. I know some people object to identifying with labels such as ADHD, autism, depressive disorder, etc., but I do not know if that is what the parent intended.
flatline··on Fable 5 On Vending-Bench: Misbehaving, With Plausible Deniability
I think the parent comment stands - I’ve asked Opus to do a review of DeepSeek’s test suite and told it a couple things I wanted it to look for, and it did a very thorough review of the tests and picked out a reasonable number of gaps and tautological tests. It’s a mix of prompting/instructions, the agent harness, and random chance. The model is not wholly irrelevant but IMO increasingly so.
flatline··on Show HN: eBook to audiobook narration with realistic AI voices
I currently parse the TOC for chapter markers, then walk the spine between markers to ensure everything is captured regardless of what the TOC says. I think it is in the spirit of what epub readers do and in line with the spec.

The eval agents perform the extraction and run a comparison of chapter/word count against the epub original. They also parse the extracted text to look for inconsistencies. The quality criteria have been built up iteratively and issues backed out into unit tests. The eval runs aren't part of my standard unit tests but a one-off, heavy lift process that I run periodically against the epub collection I already had and a bunch I built up for this project. I've also just done a ton of manual validation. There may still be edge cases.

Thanks for checking it out! The Alice link is a generated m4b, so it’s sample output that you could likely play back directly in your browser, although that may not have the cover display or chapter listing. I recommend Apple Books or Plappa on iOS, or Audiobookshelf on Android. For desktop, VLC still rules the day for general media playback, but Audibly is a Windows app that has good reviews.

There are many public domain epub files online which you could use as input. One excellent source is https://www.gutenberg.org/

I checked out your product - nice! I think we have a similar approach for a different audience. EbookAloud is basically just a two-click conversion system more geared towards consumers than content creators. Upload an epub, get an audiobook. Users will have to live with mispronounced names, etc.

Content parsing and chapter alignment were also the better part of the work here. Laying out an epub on screen is straightforward. Extracting text by chapter without duplication or elision took a lot of iterations. I could not ultimately follow the epub spec recommendation to traverse the spine, but had to rely on the TOC to drive extraction or fallback to some simple heuristics if none was present. It’s still the biggest risk area in the code and why I added a detailed chapter breakdown before asking for payment. I’ve pushed a lot of content from a wide range of sources through the code for manual and semi-automated inspection and decided it’s good enough to go live.

flatline··on Will It Mythos?
A nit: did you go from Opus 4.5 to Fable? One of the big questions in my mind is how much of a real change Fable is over the existing models. Opus 4.5 -> 4.8 was also a major capability increase.
flatline··on DeepSeek Introduces Vision
In my view, they are already chipping away at it, and have been since R1 was announced. This is the first commercial non-US tech product I've used heavily. The quality is incredible, I don't need Opus for most of my work on personal projects, I've used DS+OpenCode to create full-blown products in fractions of the time it would have taken me solo.
flatline··on Malware developers added nuclear and biological weapons text to to their spyware
When I was 7 or 8 a friend and I crimped the heads off strike-anywhere match sticks, wrapped them in foil, and struck them with hammers and rocks. They were quite loud, one even set off a sound-activated toy inside the house.

I make no claims as to how well adjusted I am, but I've at least survived 40-odd years of life since then.

I don't think anyone has a firm grasp on actual inference costs -- including the research and training that has gone into those models. We've got near-frontier capabilities from open source models from China at pennies on the dollar compared to US big tech rollouts. OpenAI and Anthropic are heavily subsidizing their inference -- no wait, they are charging the most they can get away with before going public. Where is the truth?
flatline··on Nvidia is proposing a beast of a CPU system for Windows PCs
The HN crowd is, by and large, not the target audience for his self promotion. I guarantee there is one and this is more or less effective.
flatline··on Anthropic surpasses OpenAI to become most valuable AI startup
Nothing new. I used to work with .NET and went to some meetups and conferences. There are some hardcore Microsoft fanboys out there. Didn’t even mix the kool-aid, ate it right from the packet. They only know MS products and seem scared of anything else.

Maybe not your typical HN crowd but marketing absolutely works on developers.

flatline··on Various LLM Smells
I don't disagree about the probability, but the current frontier models are not completely useless for writing even in areas where I have significant knowledge. I would not have said that a year ago. You have to watch them like a hawk -- they are good at spitting out plausible sounding nonsense that is hard even for an expert to discern. But the dice roll going on behind the scenes is continually more biased towards being correct/useful than not.
flatline··on The seed oil panic is hurting my cardiac patients
I also think this is an interesting topic of research. I have had lifelong issues with chronic pain and always felt like diet influenced it, but I’ve never been able to isolate a single factor. I’be stopped cooking with low smoke point oils but it’s all guesswork at this point.

Your phrasing about politics was potentially ambiguous, so I asked for clarification. People can mean many different things when they say something is political.

flatline··on The seed oil panic is hurting my cardiac patients
That could be a valid observation for n=1. There could be any number of reasons seed oils cause inflammation for you but do not the general populace, or not at numbers large enough to offset recommending them as a general rule.

The politicization is coming directly from the Trump administration, as the article states - making spurious claims and eliding the science that backs up the contrary conclusions. Did you have some other idea of how this is being politicized?

flatline··on Software engineering may no longer be a lifetime career
It really doesn't have to come for everything to feel like it's taking everything. If it eliminates 10% of white collar jobs over the next decade, the impact will be felt everywhere.

AFAIK all these companies have SOTA or near-SOTA models available under enterprise licenses. AI companies are not interested in your secret sauce, they are trying to capture the SDLC wholesale.
flatline··on Two Months After I Gave an AI $100 and No Instructions
It certainly thought it did all that -- this was (presumably) not written by a human.
flatline··on Bitcoin and quantum computing
I'm skeptical that B is fully possible. You can create a PQ fork of bitcoin but you cannot automatically bring vulnerable wallets along - and there are a lot of vulnerable wallets, especially from the early days. There's a catastrophe ahead for bitcoin with an apparent probability of 1.0. That's hard to account for in this scheme.
flatline··on I'm OK being left behind, thanks
The bitcoin white paper was released in 2008.

There was an EO, but that is not law. Cannabis is still schedule I last I checked. The order is to make it schedule III.
flatline··on Meta Platforms: Lobbying, dark money, and the App Store Accountability Act
People often cloak their power grabs behind a move to control some vice. It was just a bunch of us nerds on BBSs back in the day. Now everyone is online. The stakes are completely different.
flatline··on Lego's 0.002mm specification and its implications for manufacturing (2025)
I think it's more the consistency of product design than the manufacturing process. Everything around me, especially in the software world, seems to change for no good reason on a frequent basis. Companies change products all the time for reasons other than utility/functionality. A consistent specification over 50+ years is an outlier.
flatline··on Tech employment now significantly worse than the 2008 or 2020 recessions
I, too, am able to get interviews. The last time I made a serious search was in 2022-23, and companies were clearly eager to hire at competitive rates. This past fall, they were not. My salary requirements stopped at least two interview processes when the question was raised. In other cases it was not clear that the company was serious about moving forward with hiring for the position at all. A three month search ultimately came up dry, which is fine because I'm currently employed, but I do not think the hiring landscape is promising at all right now.
flatline··on Anthropic Cowork feature creates 10GB VM bundle on macOS without warning
There's a lot that's not being said in (2). That warrants more extensive justification, especially with the issues presented in the parent post.
flatline··on Ladybird adopts Rust, with help from AI
One person's waste is another's value. Do you have any idea how "wasteful" tik tok or any other streaming platform is? I'll grant that AI is driving unprecedented data center development but it's far from the root cause, or even a leading clause, of our climate issues. I always find it strange that this is the first response so many have to AI, when it poses other more imminent existential threats IMO.
flatline··on How to stop being boring
I think speaks more to a certain personality type than a set of general social protocols. This person feels like their personality was worn down to something boring by trying to fit into social systems that arguably were not designed for them. What I see here is two systems that operate at different levels of abstraction. The author's is focused on special interests, systemic critique ("be polarizing" from the post), and meta-conversation. The other is focused on lived experience, emotional shorthand, shared cultural assumptions, and relational smoothing. Neither is right or wrong, but there can be a cultural clash and misunderstandings if the two are not both recognized as valid and rich in their own way.

Not everyone is going to value weirdness. That doesn't necessarily make them boring. It doesn't mean they are incapable of revealing interesting truths about themselves - but the author may be unable to detect those for what they are due to his own cultural bias.

flatline··on Claude Sonnet 4.6
I can kill someone with a rock, a knife, a pistol, and a fully automatic rifle. There is a real difference in the other uses, efficacy, and scope of each.
flatline··on I started programming when I was 7. I'm 50 now and the thing I loved has changed
I think it represents a bigger threat than you realize. I can't use an AI for my day job to implement these multi-agent workflows I see. They are all controlled by another company with little or no privacy guarantees. I can run quantized (even more braindead) models locally but my work will be 3-5 years behind the SOTA, and when the SOTA is evolving faster than that timeline there's a problem. At some point there's going to be turnover - like a lake in winter - where AI companies effectively control the development lifecycle end-to-end.
