christianqchung··on Nipple tattooist 'frustrated' by online censorship
Pretty much any content or community that regularly self polices thought crime language I immediately dislike and block forever. I have slightly more tolerance for beeping over swear words, but not much.
christianqchung··on The internet is kind of a predatory cesspit now
Piggybacking onto your post to sort of expand this. I feel like there are a few views of what those 4 hours can encompass on the internet. My view is that reels/shorts << rage gaming <<< background noise-tier youtube << social/healthy gaming <= information binging. My problem is most reddit or twitter-esque sites make it easy to fall on the side of rage consumption, without constant self enforcement.

Now I don't think that most knowledge is really that useful in general, maybe 1% of 4 hour binges have any real consequences. But occasionally it really does turn out to be very useful. I spent maybe 4-5 hours reading and watching videos about window air conditioners, having known basically nothing but the terrible shaky units from my childhood. After that period of research time, I bought two new replacements, saved $80 with National Grid rebates, and reduced my summer monthly kwh consumption by 200-250. It also led me to information about heat pump systems which I will consider in a future house purchase, and additionally more information which led me to avoid purchasing cheap peltier dehumidifiers for one with a compressor.

I guess my point is, it can definitely be worse. You can at least point to an Ortega hypothesis-like effect of learning a bunch of random stuff. But I agree that even just going on a walk and doing literally nothing feels way, way better than spending that time online. The balance is so heavily tilted towards internet addiction that I expect that having multiple "real" offline hobbies will increasingly be seen as green flags. In my experience, "bookworm" has not been a pejorative in a long time. stackbutterflow's comment about balance seems like the most sensible way to approach timespend in this sense, though. /rant

christianqchung··on Can I Buy Your KV Cache?
I don't think Luoyuan Zhang is necessarily doing this, but I'm pretty sure lots of people are using arxiv as a glorified blog and hoping no one notices.
christianqchung··on Programming Still Sucks
Great post, thank you. At least AI won't reach this level of story quality for the foreseeable future.
christianqchung··on DRAM pricing is killing the hobbyist SBC market
If you're not a phone power user, you can get by on old low end stuff. When my pixel 4a died of a bad screen crack a couple years ago, I replaced it with a random used 4a on ebay for $80. Two years later and it's still completely fine for all my purposes (texting, phone calls, chrome browsing, tolerable camera, etc.), although I still haven't accepted google's deal for a free battery swap yet from sheer laziness. I've learned that I can accept a 90 minute screen-on phone battery, though it's an odd adjustment to make. Again, not a power user.
christianqchung··on Goodbye to Sora
I was extremely impressed by the sora demo in Feb 2024, but there are exactly two videos I remember ever seeing from AI video gen services that will stick around in my mind: the one where realistic spongebob drives away from a cop, and Harry Potter Balenciaga (2026). The original sora launch seemed pretty boring to me as a non-creative, so I only gave it a few shots (in the early semi-failed original interface). I never tried the sora 2 app since I don't like shortform video.

Disinfo AI videos and the Coca Cola Christmas ad have also really soured my expectation of genuinely positive creative uses of video gen for the next couple years until more improvements are made, and I start seeing stuff go viral for being good instead of just being weird. I am still surprised that sora never had the grok problem of generating csam or seemingly anything along those lines.

christianqchung··on Show HN: Duplicate 3 layers in a 24B LLM, logical deduction .22→.76. No training
Why test on Qwen 2.5 when Qwen 3 has been out for about a year, and Qwen 3.5 for a month? My problem with this is ironically entirely vibes based: that for some reason, LLMs love to talk about Qwen 2.5 instead of anything newer.
christianqchung··on Honda is killing its EVs
I don't disagree in theory, but:

<START AI SLOP>

Manufacturing one hardware setup and charging separately for features is not the problem. The problem is charging ongoing rent for a feature that isn't an ongoing service. A seat heater doesn't use a server, need content updates, or create meaningful recurring costs for the manufacturer after the car is sold. It shifts the relationship from ownership to permission. It also creates bad incentives: features can be removed later, tied to accounts, complicated for second owners, or turned into endless monetization opportunities.

<END AI SLOP>

christianqchung··on Teens sue xAI over Grok's pornographic images of them
Does it get flagged because of users or dang/admin? I don't see any other reason for this to get flagged.
christianqchung··on Deriving Type Erasure
Thanks for writing this. This is unrelated, but one downside of AI being used as an oracle is that I feel like it is/will be less likely to accidentally stumble on an article like this, which clearly explains something I probably never would've asked.
christianqchung··on Google restricting Google AI Pro/Ultra subscribers for using OpenClaw
You can't. Either people will say you're overreacting to stylistic choices and that it's not AI, or that it's AI but a good comment (it's not), or that it's AI and a bad comment, but you should just ignore it like any other spam.

Have you noticed that your username is literally "its_notjack"?
christianqchung··on Please don't say mean things about the AI I just invested a billion dollars in
Is it possible that these are in the top 10, but not the top 5? I'm pretty sure programming, email/meeting summaries, cheating on homework, random QA, and maybe roleplay/chat are the most popular uses.
christianqchung··on I have written gemma3 inference in pure C
A bizarre claim like that would be what happens when you let an LLM write the README without reading it first.
christianqchung··on The tech monoculture is finally breaking
I mentally checked out by the time he mentioned buying ray bans as some radical personal statement on privacy and tech nostalgia.
christianqchung··on 2026 Predictions Scorecard
Tesla? I don't love the company or the owner, but it seems silly to completely dismiss them so early on, relatively speaking. Self driving has been a decades long effort; even though I am heavily in favor of Waymo, some speculation towards Tesla's path seems fair. At the same time, I agree with the article here:

> Tesla (owned by Tesla) has put on a facade of being operational, but it is not operational in the sense of the other two services, and faces regulatory headwinds that both Waymo and Zoox have long been able to satisfy. They are not on a path to becoming a real service.

christianqchung··on Slaughterbots (2019 short film) [video]
Thought this was an interesting horror sci-fi short film about small AI drones being used as targeted weapons. While nothing quite like this has been developed, I wonder how close we can get.

christianqchung··on NIST's DeepSeek "evaluation" is a hit piece
HN admin dang changing titles opaquely is one of the worst things about HN. I'd rather at least know that the original title is clickbaity and contextualize that when older responses are clearly replying to the older inflammatory title.
christianqchung··on Demand for human radiologists is at an all-time high
> Not sure what car ownership looks like, and I haven’t been in years, but I’d imagine it’s still much more than just 20%

I said "less than 80% car ownership", not "80% do not own a car". Technically these are not mutually exclusive but I think you read it as the second one. I haven't really found much analysis about how public transit interfaces with self driving cars honestly.

christianqchung··on Demand for human radiologists is at an all-time high
Yeah, I have no idea if Waymo will ever be a rural thing honestly, mostly for economic reasons. I'm skeptical it would get serious suburban usage this decade too. But for major cities where less than 80% of people own cars, test time doesn't seem to be making a difference. They've been expanding in Austin and Atlanta, seemingly with less prep time than Phoenix and San Fran.
christianqchung··on Demand for human radiologists is at an all-time high
Look at Waymo, not Robotaxi. Waymo is essentially the self driving vision I had as a kid, and ridership is growing exponentially as they expand. It's also very safe if you believe their statistics[0]. I think there's a saying about overestimating stuff in the short term and underestimating stuff in the long term that seems to apply here, though the radiologist narrative was definitely wrong.

christianqchung··on Japan sets record of nearly 100k people aged over 100
You allegedly expending 49,000 calories in a week when the discussion is about average people is irrelevant. The post already says it depends on the person too. On the other hand, I am curious how you are possibly exercising that much.
christianqchung··on The Onion brought back its print edition and the gamble is paying off
> I'm fairly sure that's mostly consensus

The consensus is that's it's terrible try-hard partisan political satire? Can you go into more detail?

christianqchung··on US Wholesale Inflation Rises by Most in 3 Years
> Our main problems involve under the table unreported to the public military expenditures.

This is a common claim but I don't think it's supported. Defense spending is about 3.3% of GDP [0]. 15 years ago it was 4.9%, 40 years ago it was 6.45%, and it hit almost 10% in 1967 during peak spending in the Vietnam war. World War 2 made it around 35%. Also, what does unreported mean? Are you claiming that there is a significant amount of money being spent that isn't part of the reported military budget? How much? Defense spending was about 13% of the government budget in 2024 [1].

> If you look at a map of our military bases, we have many bordering China. I think our total number is close to 900.

How much do those cost? I understand the claim is a lot, but how much? If you don't know, why pick this as an example?

> Those costs are a bleeding hemorage to the middle class tax payer who aren’t getting a cut of military profiteering because they don’t own ‘defense’ stocks.

Defense stocks have not performed better relative to the Dow Jones. Raytheon stock has increased 5-fold since 1985 while the Dow has increased 33-fold over the same period. If defense was easy money, you'd see hedge funds loading up on it year on year. These companies aren't valued that much. Raytheon is valued at 208B [2], which is less than McDonalds, Nestle, T-Mobile, AMD, Home Depot, and Costco individually.

> Eventually countries that don't spend most of their treasure on their military will win. There has to be a balance between true defense spending and healthy spending like feeding and educating children, infrastructure, R&D that helps society, etc.

I agree with this, but given that America only spends 13% of the budget on the department of defense, your own claim is claiming an American win. In 2021 the American Rescue Plan induced a giant amount of domestic welfare spending plans such as almost doubling the child tax credit. This was a tremendously expensive plan that cut child poverty in half, but people didn't feel strongly enough to successfully pressure politicians to keep it, which does seem pretty frustrating to me.

Also, I see you're using AI for sources below. Feed your comment into GPT 5 thinking and ask for an opinion, because it apparently thinks your inflation claim is completely reversed.

christianqchung··on GPT 5 Predictions
Hi, I thought it would be interesting to post some predictions for GPT 5 I wrote up yesterday and to hear what others expect. I wish I posted it yesterday because a section about model sizes has been confirmed by a leak. Sorry about the bad formatting in some areas, I didn't get a chance to fix them this morning.
christianqchung··on Open models by OpenAI
A little bit of training data certainly has gotten in there, but I don't see any reasons for them to deliberately distill from such an old model. Models have always been really bad at telling you what model they are.
christianqchung··on Open models by OpenAI
> Training: The gpt-oss models trained on NVIDIA H100 GPUs using the PyTorch framework [17] with expert-optimized Triton [18] kernels2. The training run for gpt-oss-120b required 2.1 million H100-hours to complete, with gpt-oss-20b needing almost 10x fewer.

This makes DeepSeek's very cheap claim on compute cost for r1 seem reasonable. Assuming $2/hr for h100, it's really not that much money compared to the $60-100M estimates for GPT 4, which people speculate as a MoE 1.8T model, something in the range of 200B active last I heard.

Facebook users do not know Llama anywhere near the degree the X network does Grok, and both are pallid in comparison to Chatgpt.
