NhanH··on Cousins are disappearing. Is this reshaping the experience of childhood?
I read it as describing the situation being weird. The people being normal is what makes the whole thing weird
NhanH··on Edsger Dijkstra carried computer science on his shoulders (2020)
The whole structured programming practically birthed the industry, so it’s hard to say he has less direct impact in the industry though.
NhanH··on 'They're knowingly addicting kids': the attorney challenging social media firms
Yes, China did it with Alibaba. They wrote off 1T or more in notional value.
NhanH··on Epistemic Learned Helplessness (2019)
Yeah, it's a bit disheartening to hear some (presumably) experienced people advocates for never allowing the junior to dig and deal with things on their owns.

I can imagine the scenario where a build fail due to some missing incantations that needs to be invoked, and sure, you shouldn't spend more than 15 minutes on trying to resolve it. But that should be rare, while the common blockers for junior tend to be their lack of understanding in even bog-standard systems and situations (why can't system X do Y, why did person Z require A). In those cases, part of the expectation when assigning them the work would be for the junior to learn those on their own.

NhanH··on Epistemic Learned Helplessness (2019)
The nuance here lies within the “hours” quantifier.

A junior member being blocked for 3-8 hours semi-regularly is expected. Once every other month you probably should be blocked for several work days as well.

In your example, the challenge would have been realizing you wouldn’t have been the first one trying to send an email in the team. Recognizing that and it is very easy to know that you should just ask the question right away. It’s not a technical skill, but something a bit more meta.

NhanH··on What does the cerebellum do?
Human society provides nowhere enough pressure for evolution to have effect (for good reasons), and our humanity timeline is nowhere near lengthy enough so far either. So I don’t think we are heading anywhere in that regards
NhanH··on Orange Site Hit
Those arguments are just another echo chamber where the echoing content itself is meta rather than specific. So instead of "X is Y", it's more like "you should use method Z to determine whether X is Y". It's just the same breed of "correlation is not causation", "more critical thinking is needed", or "citation needed" as you mentioned.
NhanH··on Orange Site Hit
HN is a giant echo chamber. Some people dislikes any and all echo chamber, regardless of the bias. And then you have people disliking the slant of HN's echo chamber as well.

To put it another way, HN as a whole has strong opinions on a lot of things. And anyone or anything with strong opinions will have people disliking them, for better or worse :-)

NhanH··on Show HN: Rem: Remember Everything (open source)
Serious question: I have a serious case of OCD where I keep trying to remember things verbatim (the verbatim part is the OCD). Naturally there are a bunch of checking and repeating in trying to do so.

I have been considering the idea of using a similar app to this (or rewind.ai), but I have the concern that it might aggravate my situation. Just imaging my checking self watching 12 hours of video footage already gave me chill.

I would appreciate if anyone with a related or similar situation can share their experience using those apps. Since this is fairly sensitive, my email is also in the profile if anyone want to contact me directly.

NhanH··on Rolex fined $100M for preventing its watches being sold online
Good replica is nigh impossible to distinguish with real one without a real one to compare. But they are not identical to the real one. In fact each good replica is manually assembled and you get to QC your actual watch when order (via photos).

That is to say if you have a real and a replica to compare, there is no risk of mistaken between them. There would be difference which you could easily recognize.

NhanH··on Voyager 1 stops communicating with Earth
I am guessing the number comes from multiple systems of independent sensors. So the assumption is that they won’t all fail at the same period in the same way
NhanH··on It's Still Funny That 1k People Gave Tesla $250k for a Roadster Six Years Ago
You are claiming thay current human driven taxi/ car rides market are making 700 billion dollar profit per year (70B / 10%)

They don’t

NhanH··on Ask HN: Why GPT-4 latency increases for uncommon questions?
I am guessing it might not be the main transformer that is occasionally slower, but rather a secondary LLM that is used to censor stuffs which occasionally runs ?

So basically the unusual answer needs more additional processing to make sure it is "safe" to be streamed to the client.

NhanH··on OpenAI researchers warned board of AI breakthrough ahead of CEO ouster
That is just Q. The asterisk is new
NhanH··on Ask HN: Best monitor for a MacBook Pro for ~US$700?
Pick a 4K in your price range from Dell or LG and you should be good to go.

Outside the US, recommending specific display is not particularly useful since stocks is an issue, not to mention the model would be straight up unavailable to you.

NhanH··on Three senior researchers have resigned from OpenAI
I am not second guessing the 10x engineer, that topic is not the one under discussion.

The topic at hand is “how did a high level engineer got to focus on programming”. And I am saying that the reason has to do more with his influence and role within the organization, rather than other reason.

NhanH··on Three senior researchers have resigned from OpenAI
It's not about being rockstar or 10x. He was the chairman of the board (and President of the LLC). Practically speaking, he can work however he wishes within the company. Seeing that he went from CTO role to President role, it's fairly obvious that he got the opportunity to structure the role and the work to best fit him (and probably the company, too).
NhanH··on Your small imprecise ask is a big waste of their time
The other pitfall of trying to clarify all assumptions is that your message then becomes too long. Then the reader actually will skim over the main points, which makes it worse.

So yeah, it takes a lot of works to communicate efficiency, no matter the length of the end results

NhanH··on UN chief warns Nepal's mountains have lost one-third of their ice
That’s the problem though. China is already building more renewables than any where on the world (probably more than the rest of the world combined). They still have to ramp up coal production to meet demand despite all those growth. The question isn’t about whether to build more renewable, but how.
NhanH··on California employers must reimburse remote workers for all necessary expenses
It's not just opportunity cost. I have known people buying condo with extra room to use as home office (they picked the one with extra room). It is a very real and significant cost, not merely opportunity cost
NhanH··on Why Apollo 11 astronauts signed tons of autographs – then stowed them away
The communication cut off would have happened AFTER the astronauts said their goodbyes.
NhanH··on Ask HN: If GraphQL Is So Great, Why Doesn't Everyone Use It Already?
Don’t build a generic API for your specific interface.

Unless you have hundreds or thousands of developers consuming an API endpoint, it’s generally better to build the API tailor specifically for each screen/ use cases/… you have. When thinking about API that way, the value of graphql is not that clear anymore

NhanH··on Kata Containers: The speed of containers, the security of VMs
That is not an obscure issue. The common manifestation is breaking iptables rule (with expose port) and messing up software firewall has caused a lot of wasted hours and security issues.
NhanH··on Extracting Hacker News book recommendations with the ChatGPT API
The author name is wrong for Meditations (though it links to the correct book)

It’s Meditations (by Marcus Aurelius).

NhanH··on Richard Stallman reveals he has cancer in the GNU 40 Hacker Meeting talk [video]
I will answer this assuming good faith, but this line of reasoning is very irritating since the answer (to me) is obvious.

If RMS made a choice to use proprietary software, with the only alternative being his dead, there is absolutely no moral conflict, or even anything against his principle. The only issue could only ever arises if he claimed "Free Software is more important than human lives", which I am pretty sure not a claim he, or anyone, has ever made.

It's basically the same principle as if you point a gun to my head and tell me to kill a puppy or get shot (and I'm certain you would shoot me). It's obvious which choice I would make, and I hardly see that as an evidence of my hatred for puppy.

NhanH··on There's a mechanical watch feature called a “hack”
+- 2 seconds per day is their worst case specifications (watches being stored in weird orientation, with high temperature etc.). It is common for standard usage watch to be within 10 secs monthly.
NhanH··on Ask HN: Is there a technology you loved but had to abandon?
Typescript is backed by Microsoft. And quite literally no organization has a better track record than them in supporting and growing development tooling forever.
NhanH··on My solopreneur story
He was Communist Vietnam born and raised.

Funny enough, this type of entrepreneurship is more common in Vietnam than the US (I have lived in both, now in Vietnam).

NhanH··on Show HN: Odin – the integration of LLMs with Obsidian note taking
I made the same conclusion and started making a tool on my own from scratch! Turned out it did take much less effort to build something you are happy with than tweaking existing tools.

PWA with Rails/React, editor is Lexical (because why markdown when you can have note looks pretty), hosted on a machine at home that I connect via tailscale.

I already added LLM integrations too.

NhanH··on We have successfully completed our migration to RAM-only VPN infrastructure
Even if that attacks has close to 100% success rate, I'd imagine it being nigh physically impossible to execute a targeted attack, as you don't know which machine to hit for a specific user. And that seems to be the main threat model we would be concerned about for this.
