dinobones··on Show HN: Lunon – Instant model switching across LLMs
Nice webpage/design, but what is the advantage over Openrouter that already has ~trillions tokens/month in traffic?
dinobones··on OpenAI's o1-pro now available via API
Interesting... Most benchmarks show this model as being worse than o3-mini-high and sonnet3.7.

What difference are you seeing from these models that makes it better?

I say this as someone considering shelling out $200 for ChatGPT pro for this.

dinobones··on Google to buy Wiz for $32B
This makes no sense.

Assume 1,000 customers each generating $2m in ARR with contracts. That’s $2 billion. Assume generous 6x ARR valuation, that’s $12 billion.

Where is this $20 billion premium coming from? How could the board approve this? How is this fair to shareholders?

Heck, as a minor shareholder in GOOG, I don’t find this financially responsible at all.

I can’t help but think sometimes these tech acquisitions have some hint of nepotism/deeper underlying motivations behind them than meets the eye.

dinobones··on Tesla fans exposes Tesla's own shadiness in attempt to defend Autopilot crash
There's more shadiness behind Tesla's autopilot/FSD history...

- Actually, blatantly faking videos of Tesla FSD.

- Elon claiming unsupervised NY to LA would be possible by end of 2016 (almost 10 years ago).

- Elon claiming all cars sold today (years ago) have required hardware to become robotaxis.

- Tesla salesmen of the past telling customers their cars were investments because they would become robotaxis that would make money.

Theranos lasted 15 years, so I'm surprised $TSLA is being called this early.

As someone who personally knows people in the industry, I'm pretty confident in saying that TSLA will never actually deliver any type of robust, safe autonomous driving system. The organization itself is just not capable of it anymore.

All that are left are people trying to game metrics and not get fired, that type of culture just can't produce it.

dinobones··on “Normal” engineers are the key to great teams
Yeah maybe if my employer has the ambition to pay.

Am I working hard at Meta? You bet I am.

For median SWE salary and 0.001% in “options” that will likely never have a liquidity opportunity? I’m not so sure…

dinobones··on You might not need Redis
It’s not about Redis vs not Redis, it’s about working with data that does not serialize well or lend itself well to extremely high update velocity.

Things like: counters, news feeds, chat messages, etc

The cost of delivery for doing these things well with a LSM based DB or RDB might actually be higher than Redis. Meaning: you would need more CPUs/memory to deliver this functionality, at scale, than you would with Redis, because of all the overhead of the underlying DB engine.

But for 99% of places that aren’t FAANG, that is fine actually. Anything under like 10k QPS and you can do it in MySQL in the dumbest way possible and no one would ever notice.

dinobones··on Canada Retaliates, Puts Tariffs on $107B of US Products
The reason is: It doesn't affect their pocket books.

Meanwhile property prices and 401ks are up, old people (the largest cohort of voters) really just don't care.

I wish people had more empathy for others, but they don't. They mostly only care about taxes and their personal wealth.

This level of personal greed-individualism is partly what makes America great in the good times, but awful when things get bad.

dinobones··on Elon Musk's DOGE reportedly gained "full access" to the federal payment system
I don't understand how Andreessen, Thiel, and the rest of the the "alt right tech" prefer this and "anti woke" to some non-consequential DEI lip service and a functioning government.

Oh well, as long as he's "one of us" right? Who cares about national security, privacy, etc... Trump will pardon him and DOGE will have much win much budget cuts amirite?

dinobones··on AI haters build tarpits to trap and trick AI scrapers that ignore robots.txt
ok...

if depth > 5 and if sem_hash(content) in hist: return

dinobones··on Meta announces 5% cuts in preparation for 'intense year'
uhhhhhh.. Ok, they’re from two countries, but mostly one.
dinobones··on Stop making me memorize the borrow checker
I've written a ton of software, both backend and embedded-like software in C++.

What are people writing that requires such fancy/extensive usage of the borrow checker?

I can't even remember the last time I had to use a shared_ptr... unique_ptr and other general RAII practices have been more than enough for our codebase.

dinobones··on NASA Jet Propulsion Laboratory lays off another 5 percent of workforce
> Take low paying government job for job security.

> Low paying government job is not secure.

dinobones··on MrBeast did not pay for 1k eye surgeries
The guy who made this video is pretty weak on how to communicate effectively.

Spends like 6 minutes with a creepy cardboard face of MrBeast in the clinic and performing "eye surgery" on him tf?

It's still not clear to me what happened; did Beast interact with him and tell him he would pay and never did? Did Beast just show up to his clinic and make the whole thing up?

This only has 17k views and was uploaded 8 months ago. It's because it's incoherent, the story or situation is not clear at all. With effective storytelling this could have gone viral, ironically, effective storytelling like the kind that MrBeast used.

dinobones··on Vector databases are the wrong abstraction
Wow, actually a good point I haven't seen anyone make.

Taking raw embeddings and then storing them into vector databases, would be like if you took raw n-grams of your text and put them into a database for search.

Storing documents makes much more sense.

dinobones··on Using reinforcement learning and $4.80 of GPU time to find the best HN post
I am trying to understand this too.

Supervised learning you train on pairs of (x, y) where x is your input (title/post text/metadata) and y is the output score.

Naively, it's a linear regression model, Y = b0 + b1x1 + b2x2 + b3x3. Where b0 is your bias ("a floor for score points"), and b1, b2, and b3 are bias terms for the actual data of the post. You can solve this, closed form, and find the b1/b2/b3 that minimize the error of fitting to Y.

How do these equations change with RL? I always assumed RL was a multi-step process where actions are taken to get to a reward. If there is only 1 step/decision, to produce a "random" score, it feels much like supervised learning.

dinobones··on Florida Eases Licensing Requirements for Foreign Trained Doctors
Does this mean Caribbean medical school is less of a scam now?
dinobones··on Ultra fast key value store (in C btw)
I personally prefer "dear leader"
dinobones··on Learning to Learn
I've been wanting to try this approach for learning a language.

In English for example, learning the 800 most common words, you can understand 75% of the language: https://www.bbc.com/news/world-44569277.

I'd love to start fresh on a new language, take 800 new words, try to learn 10 a day, and see where I get after 3 months. Can I really understand 75% of text if I have perfect recall of those 800 words?

dinobones··on Saudi Arabian Neom project 'uses one fifth of world's steel'
There’s this guy on every comment.

The vast majority of human experience has been tough. Arguably the vast experience of most life is pretty cruel.

Should they just donate the wealth of their country to some other one? Would you like to donate some of your personal income to the nice homeless people outside?

The leaps from people build dumb glass city => world is bad => people building dumb glass city are bad because world is bad aren’t obvious to me.

dinobones··on Skip Hash: A fast ordered map via software transactional memory
I love that new, performant data structures are still being found in CS.

It's easy to forget that it's still such a new and early field. The modern version of CS started in what... the 50s, earliest? There are many people alive today who are older than the study of CS itself.

dinobones··on Show HN: PostalAgent – Send Postcards online by circling areas on a Google Map
Very nice website, I appreciate the mailing list demo. I was skeptical about how much data you would have ,and the mailing list demo convinced me and probably many others that you have a good amount of data to offer a quality service.
dinobones··on Software Engineer Pay Heatmap Across the US
Can levels.fyi stop showing non-liquid pre-IPO startup equity as part of total comp please?

You'd be surprised at how difficult it is to get liquidity for that stuff, often there are limits to the amount you can liquidate, some can't sell on private marketplace, some can only sell every once in a blue moon event, etc. This is all without mentioning that the "valuation" itself is typically pretty speculative.

Levels.fyi is treating this equity the same as public company RSUs, which is not the same at all.

dinobones··on Dropbox Co-Founder Claims JPMorgan Advisor Cost Him over $225M
These types of "financial advisers" are the Gucci bags of the investment world.

Basically you pay them a lot of money just so they puff you up on the phone and make you feel important.

Someone will come in and argue, "but they can help mitigate risk, and and alignment with financial goals and timelines." ... Yeah, and so does just investing in index funds yourself and reducing your "risk" by allocating some % into bonds.

dinobones··on Math from Three to Seven
Good example of passion from early bell Labs: https://www.youtube.com/watch?v=tc4ROCJYbm0

Other examples I can think of (from my Gen Z experience, growing up in SoCal):

- Elementary school: Making custom action replay codes, hacking game saves with programs, CheatEngine/memory/hex editor and following YouTube tutorials, Javascript "document.contentEditable=true" hack and changing stuff on websites, pressing F12 and changing random javascript code until something interesting happens or breaks.

- Middle school: making sites on Weebly/freewebs, embedding chats and flash games on them, sharing them during computer class

- High school: Making PHP sites/vbulliten/Newgrounds/flash games, later iOS apps

I wasn't the only one doing these things. There were always like 3 other kids like me in any classroom that would do the same things.

Most of us ended up becoming passionate SWEs, besides one that became an accountant.

dinobones··on g1: Using Llama-3.1 70B on Groq to create o1-like reasoning chains
OAI revealed on Twitter that there is no "system" at inference time, this is just a model.

Did they maybe expand to a tree during training to learn more robust reasoning? Maybe. But it still comes down to a regular transformer model at inference time.

dinobones··on Learning to Reason with LLMs
This new approach is showing:

1) The "bitter lesson" may not be true, and there is a fundamental limit to transformer intelligence.

2) The "bitter lesson" is true, and there just isn't enough data/compute/energy to train AGI.

All the cognition should be happening inside the transformer. Attention is all you need. The possible cognition and reasoning occurring "inside" in high dimensions is much more advanced than any possible cognition that you output into text tokens.

This feels like a sidequest/hack on what was otherwise a promising path to AGI.

dinobones··on Learning to Reason with LLMs
I am interpreting "immediate use in ChatGPT" the same way advanced voice mode was promised "in the next few weeks."

Probably 1% of users will get access to it, with a 20/message a day rate limit. Until early next year.

dinobones··on Learning to Reason with LLMs
Generating more "think out loud" tokens and hiding them from the user...

Idk if I'm "feeling the AGI" if I'm being honest.

Also... telling that they choose to benchmark against CodeForces rather than SWE-bench.

dinobones··on 100M Token Context Windows
Long context windows are IMO, “AGI enough.”

100M context window means it can probably store everything you’ve ever told it for years.

Couple this with multimodal capabilities, like a robot encoding vision and audio into tokens, you can get autonomous assistants than learn your house/habits/chores really quickly.

dinobones··on Using $300 robot arms and a MacBook to fold a T-shirt
Put it on wheels. Give it a chute for dirty clothes.

I'd happily pay 10x this ($3,000) to never do laundry again if it meant nicely folded clothes would always await me in my closet.
