jlei523··on AMD claims Arm ISA doesn't offer efficiency advantage over x86

  Intel and AMD have implemented these improvements with Lunar Lake and Strix Halo. You can buy an x86 laptop with Macbook-like efficiency right now if you know which SoCs to pick.
This just isn't true. Yes, Lunar Lake has great idle performance. But if you need to actually use the CPU, it's drastically slower than M4 while consuming more power.

Strix Halo battery life and efficiency is not even in the same ball park.

jlei523··on Tesla Wants Out of the Car Business
I think anyone could have seen this from miles away based on:

1. China is going to own the EV market. The only thing that can temporarily stop Chinese EVs from dominating in every country is massive tariffs. But this is not a long-term strategy.

2. Sentiment is low on EV due to Trump

I think the problem with Musk's strategy is that self-driving will also become a commodity over time. There's no reason that only Teslas will be able to drive themselves. Further more, I don't see why China's robotics won't do the same to Tesla's EVs. In fact, I believe China's robotics are world leading at the moment.

jlei523··on Using Claude Code to modernize a 25-year-old kernel driver
"Use DRY coding". 3 words can solve this problem. Maybe put it in the parent prompt.

I disagree with you. You don't need researchers to use your client hardware in order to make inference chips. All big tech are making inference chips in house. AMD and Apple are making local inference do-able on client.

Inference is vastly simpler than training or scientific compute.

  Also I wanted to add that LLMs (at least free ones) are pretty dumb sometimes and do not notice obvious thing. For example, when writing tests they generate lot of duplicated code and do not move it into a helper function, or do not combine tests using parametrization. I have to do it manually every time.
Do you prompt it to reduce duplicated code?

  The new CEO of Intel has said that Intel is giving up competing with Nvidia.
No, he said they're giving up competing against Nvidia in training. Instead, he said Intel will focus on inference.

That's the correct call in my opinion. Training is far more complex and will span multi data centers soon. Intel is too far behind. Inference is much simpler and likely a bigger market going forward.

jlei523··on Ask HN: How did we go from wanting AGI to asking a 6 month pause on it?
>We need to solve AGI now?

No, we need to solve the problem of AI alignment, regulation, etc now.

jlei523··on Ask HN: Is the only way to regulate AI through chip fabs?
Funny enough, perhaps the AI threat is what will bring China and US back on friendlier terms. If there is a greater threat than both, they'll work together.

I think signing an AI treaty between the two countries will do a lot for the world.

jlei523··on Ask HN: How did we go from wanting AGI to asking a 6 month pause on it?
I don't see it as hype to be honest. It's a real problem we need to solve now.

Also, it seems like the letter was faked?

Anyways, it doesn't matter if it's faked. It does make people notice that it's a real problem now.

General consensus amongst data scientists of when each AI breakthrough will happen have almost always been wrong. AI breakthroughs tend to happen earlier than what the consensus predict. I don't see AGI predictions as any different.

jlei523··on Ask HN: Is the only way to regulate AI through chip fabs?
How do we make sure no country builds an underground nuclear weapon making facility?

I don't actually know the answer to the above question.

But at least for chip making, you need hundreds of different highly advanced technology suppliers and chemicals to make a chip. I would think that making an advanced chip making facility is actually much harder than nuclear weapons. Many countries have the ability to make nuclear weapons, but no one can compete with TSMC, Samsung, and Intel right now. Even then, all 3 rely on ASML machines.

That said, I suppose countries will slowly see the value in chip manufacturing and invest heavily into it in order to train more powerful AI models.

I'm not suggesting that this solution is perfect, but it does seem to buy us significantly more time.

jlei523··on Ask HN: What is Apple doing now with all the AI/GPT/LLMs buzz?
For Siri specifically, Apple has to be extremely careful. Their carefully crafted public relations could shatter in an instant of their LLM spits out crazy answers like Bing's chatbot.
jlei523··on Do data-driven companies win?
A/B testing can definitely make product teams feel like they're making progress but it should not be a team's only strategy.

It's a bit like moving the furniture around the same room.

jlei523··on Lyft lays off 17% of workforce, furloughs hundreds more
I really don't think Waymo needs Lyft or Uber to dominate the ride hailing market in the future.

If they can make a better self-driving car than anyone else, they will win the ride-hailing market. People have no loyalty to Lyft or Uber. They will use whatever is the cheapest/most convenient.

jlei523··on Covid-19: Only 268 cases and no deaths. How did Vietnam with 97M people do it?
American living in Vietnam right now.

The first part of your post is true.

The second, is in my opinion, completely false.

As others have mentioned, the government is incredibly diligent in tracking the virus. And why shouldn't they? They were freaked out by SARS in 2003 and as a growing 3rd world country, they simply cannot afford to have the virus spread.

Also, if one person gets the virus or one person is placed in quarantine in Vietnam, it's all over Facebook and shared. The government can't hide shit when it comes to the virus.

jlei523··on Beginners guide to gateways and proxies
Seconded! Companies that intentionally leave out the pricing is automatically blacklisted to me. It shows that the company is not transparent.
jlei523··on Probing Facebook's Misinformation Machine
Same! The initial tweets are generally ok.

But as soon as you scroll down, the comments make you want to throw up.

jlei523··on Probing Facebook's Misinformation Machine
Yes agreed. I tried using Twitter to promote my work but I found Twitter to be even more toxic than Facebook in general and have since quit.

I'd argue that Reddit also does the same thing. On Reddit, you can always find a community that agrees with your radical thinking. Reddit also has a problem with groupthink where the upvoting system heavily rewards popular opinion, even if it's false.

In this day and age, I find that not participating in social networks makes me a happier and less radical person. If I do partake in them, I limit myself to generally harmless hobby and work-related communities.

jlei523··on Probing Facebook's Misinformation Machine
For many years, I resisted from using Facebook. Recently, I started using it more to connect with friends and family.

And holy shit. The amount of misinformation, fake news, and conspiracy theories on Facebook is insane. Facebook is a machine that breeds extremists.

I now understand the #deleteFacebook movement much more where I previously thought it wasn't a big deal.

jlei523··on Jitsi Meet Electron 2.0
Why do people hate Zoom so much? I just received an email today from Zoom outlying all the fixes they just released.

They went from 10m users/week to 200m/week in less than one month.

So what they struggled? Most products would struggle with that kind of ramp up. They owned up to it and fixed pretty much all the complaints. And they're providing a valuable service to the world, most of it for free.

Stop hating Zoom.

jlei523··on Apple to debut multiple ARM MacBook, desktop models in 2021
You're thinking enterprise.
jlei523··on Apple to debut multiple ARM MacBook, desktop models in 2021
Apple spent the last 4 years backtracking on features they introduced in 2016:

- Keyboard with more travel - ESC key

Now people are calling the 16" the greatest laptop ever. It's like you've been abused for 4 years, then the abuser does something nice, and you think he/she is the nicest person in the world.

Macbook Pros are still bad:

- Useless touchbar that makes basic functions harder - Resting your palm over an oversized touchpad - Dongle-hell - No battery life improvement in 8 years - Overpriced due to focus on thinness and useless touch bar

They should have taken the 2015 Macbook Pro and gave it a 16" screen, touch ID, newer ports, newer CPUs/GPUs and it would have been 10x better than the overpriced junk we have today.

It's only confusing to a small minority of buyers.

Most people who buy these laptops know nothing about Zen2, Zen1, Zen+.

jlei523··on Performance: AWS RDS Postgres vs. Digital Ocean Postgres
True.

But a managed service means I'm paying you money so you can optimize the database to its fullest for me.

Hopefully DO can improve on its performance overtime.

jlei523··on WeWork’s Back Is Against a Wall
>but high enough that the masses of 1-movie-a-month ordinary users support the 30-movies-a-month power users

How would this work for WeWork though? If someone rents the space, WeWork can't rent it out to someone else. And this is work. People are going to show up on most days - unlike gym memberships.
