enjeyw··on Embeddings are underrated
Haha yeah I was about to comment that I recall a period just after Word2Vec came out where embeddings were most definitely not underrated but rather the most hyped ML thing out there!
enjeyw··on Ghost jobs are wreaking havoc on tech workers
I like it! Frankly, it should be something that hiring companies do anyways.

Perhaps extend it to something like everyone who applies, or responds to your comment”

Practically speaking, enforcement will be difficult/impossible for actions off HN - if someone claims a company isn’t responding, or using a templated email, how would you verify that?

By enforcing the same rule for a job thread, there’s a very clear location where the behavior of the company can be observed.

I think you’re getting downvoted because “yeah yeah yeah” is normally a sign that someone is sarcastically dismissing an idea, but the rest of your comment suggests you’re not at all - linerp is a great idea!

Are you offering shares in your venture? I’d be mildly interested in investing on the expectation that I’d see returns that are slightly worse than inflation.

Not that interested though, so whatever.

enjeyw··on Science fiction authors were excluded from awards for fear of offending China
I have no personal insight into Confucius Institute censorship, but the reason I wrote “nation states” rather than China was because I agree, this applies in all directions.
enjeyw··on Science fiction authors were excluded from awards for fear of offending China
I dislike the use of the world “offending” in the context of nation-stakes; it conjures this air of innocence around the state is if their primary failing is one of being overly sensitive.

A better albeit wordy phrasing would be “for fear of invoking retribution from China as a consequence of not conforming to their authoritarian desires”.

enjeyw··on Ask HN: Are there any good reasons to use C++ over Rust for new projects today?
I understand your hesitation, but I’d really appreciate your take, given you seem to know your stuff.

Personally I think the sibling comment is pretty accurate, and rust is held back by:

- slow compiling of larger projects

- async stuff can quickly lead to very complex shenanigans

- embedded still requires you to write HAL stuff for MCUs that is supported out of the box for C

enjeyw··on Prediction markets have an elections problem
Yeah as far as I’m aware that’s the solution. Though then the market can’t use the deposit to make money for themselves, and needs to rely on other mechanisms like trading fees etc. So really it comes down to how much the market cares about the accuracy of long tail events.
enjeyw··on Prediction markets have an elections problem
I worked at a prediction market startup for a while.

Even completely rational prediction markets generally have a structural problem with events with likelihoods close to 1.0 or 0.0. This leads to cases where conspiracy type events have much higher likelihoods than they should, leading people to assume the market has lost all rationality when actually it hasn't.

For example, imagine if there's an event with a predicted likelihood of 1 in 50, but it should actually be 1 in 1000.

Assuming the market uses real money, then on paper someone should be able to make a roughly 2% return by betting that the event won't occur. However, if this market isn't closing for a while (for example for an election at the end of the year), then no-one is incentivised to take the bet and correct the market, because they'll get a much better risk free return just by putting their money in a term deposit and collecting the interesting. And so the market remains un-corrected. Basically prediction markets have an accuracy upper bound determined by the current risk free return.

For markets using "play" money a slightly different effect is at play. When it's not real money involved, generally the people are incentivised to try and top a leaderboard of some sort. In this case, a really effective strategy for people who currently aren't near the top of the leaderboard is to take long shot bets. If they loose, who cares they weren't gonna win anyways, but if the the bet plays off they have a lot to gain. Basically there's an asymmetry in returns that once again messes with probabilities.

enjeyw··on Show HN: Coffeehouse, one-on-one voicechat with random HN users
It’s times like these I’m so glad we allow resubmissions. This is such cool piece of work and the HN-specificity of the audience means that the only real path to success is via a submission that makes the front page
enjeyw··on New insights into neural end-of-life
Yeah this is something I've also tried to grapple with.

I think you have a point with the rats - they're clearly very intelligent creatures, which is unfortunately also makes them so valuable for this kind of research. So it comes down to a trade off between improving human lives at the cost of another less intelligent but nonetheless very much aware creature.

While norms will likely shift over time, I don't think it's really possible to establish consensus view on this sort of thing - everyone will have the own level of comfort, just like eating meat.

Making absolute statements about the sanctity of life I think I'm a little more comfortable making a concrete statement on. If you embrace an absolutely view sanctity of life, just existing basically becomes impossible - how do you deal with the insects you accidentally kill when you walk on grass? What about the bacteria that your body kills during an infection? It's just not workable.

As for experimenting on people on death row, my gut is that to the extent that Capital Punishment Exists (something I'm against for what it's worth), it cannot have any external utility derived from the process. Rather it needs to exist purely as part of the justice system.

If there's an exogenous utility being derived from Capital Punishment, I think there's an unacceptably high risk that the motivations for capital punishment will become twisted. To put forward a hypothetical, but not infeasible scenario:

  - We allow scientific experimentation on death row inmates
  - Then, a lobby group points out that we could save even more innocent lives by using the inmate's organs for donation rather than experimentation. It's the same fundamental thing, just a different use.
  - Then, there's a small but meaningful pressure on the justice system to find more people guilty in order to keep the flow of life saving organs strong. (We already know what the justice system is susceptible to this sort of pressure, see forced labour)
As a flow on effect, this makes it much harder to roll back capital punishment in the future if a society decide it's harmful, because there's a flow on effect of loss aversion towards that exogenous utility. I've seen this happen in my own state (Victoria, Australia) when it comes to gambling - we broadly acknowledge slot machines are extremely harmful, but the government struggles to curtail their use even slightly, because the tax revenue generated from them is used to fund important services. The harm is greater than the gain, but the loss aversion of those services is too powerful.
enjeyw··on MeshGPT: Generating triangle meshes with decoder-only transformers
If you’re willing, I’d love your insight on the “why one might want to do this”.

Conceptually I understand embedding quantization, and I have some hint of why it works for things like WAV2VEC - human phonemes are (somewhat) finite so forcing the representation to be finite makes sense - but I feel like there’s a level of detail that I’m missing regarding whats really going on and when quantisation helps/harms that I haven’t been able to gleam from papers.

enjeyw··on Ask HN: What are you passionate about at the moment?
Personally, I intersperse my running with Interval Training on an exercise bike: 2 minutes out of the saddle with the resistance turned up a bit, pushing as high as you can go, 1 minute of easy riding in the saddle with low resistance. Repeat 7 times.

I think it provides a few advantages to your running:

- it’s excellent cardio, so it’ll improve your VO2 max, which is hugely helpful for both running and living longer

- it’s low impact, so it gives your joints time to recover. Recovery is critical for an impact sport like running!

- the resistance builds leg strength, so it makes you more resilient on longer runs

Oh, and get a decent pair of running shoes, ideally from a store that knows what they’re talking about. Note that the best shoe for you won’t necessarily be the most expensive one - things like whether your over pronate or not are critical, so don’t go out and buy the latest carbon sole foodad just because that’s what the pro’s have.

enjeyw··on Intermediate sci knowledge associated with overconfidence and negative attitudes
In highschool I was lucky enough to join a program run by the CSIRO (Australia's Government funded scientific research body), where students would assist scientists on experiments they were conducting.

I was tasked with measuring the water resistance of a proposed environmentally friendly paper coating.

I asked my supervising scientist what numbers I should expect to get back from the experiment. I distinctly remember my surprise and thrill when he looked at me and said "I have no idea, that's why you're running the experiment".

It was such a new concept to me! A scientific experiment where the correct answer wasn't written in a teacher's lesson guide, or even known to anyone!

enjeyw··on The sudden demise of Indian vultures killed thousands of people
> The delicate balance of Nature was upset.

Fascinating stuff. A subtle build on this that just struck me: "The delicate balance of Nature moved to a new equilibrium point that involved a lot more human deaths"

I think it's interesting because it strikes me that Nature is actually a pretty resilient system, it's just that a lot of its stable-states are hostile to human life, to varying degrees. Then again, maybe I'm painting too much of an anthropocentric picture.

enjeyw··on Russian paramilitary chief says his forces will turn around
>Third observation was unexpectedly high visible support of Wagner by people. Many laughing at situation or agreeing with Prigozhin‘s demands, some bringing food and water to mercenaries in Rostov. All despite that PMC Wagner is a criminal organization famous for extra-judicial executions, war crimes etc. An organization led by an open nazi (Utkin) and assembled from prisoners, many of which were convicted for violent crimes. It is crazy how people can even think of collaborating with them.

This raises an interesting question for me.

The invasion of Ukraine enjoys popular support inside Russia - around 70%. The justification continuously put forward regarding why such a large proportion of the Russian population supports the invasion is that they've been brain-washed by state media into believing that Ukraine requires "de-Nazification".

That the Wagner group enjoys such popular support, while their Nazi sympathies are also common knowledge^ makes this justification questionable.

My best, admittedly totally speculative, guess right now is that the Russian populace has a far better/non-brainwashed understanding of the geopolitical situation than what is commonly suggested, and that while everyone is happy to go along with the de-Nazification pretence, in reality the populace harbours the same ambitions for a return of Russian imperial power that the Russian leadership does, and also holds similar moralistic perspective.

^I believe this to be the case, but I'm not certain. At the very least there doesn't seem a state sponsored campaign to hide it

enjeyw··on Web3's fake version of Web history
At least for the 3D printing case you may have just been too early, or the wrong market.

I work at a hardware company and these days 3D printing is invaluable for prototyping and other similar work.

Maybe in a couple of years the same will be true for the others.

enjeyw··on Forbes mocked as another '30 Under 30' honoree accused of fraud
As someone on the list, here’s a moderating view against to the popular take of narcissists campaigning to get on the list (which definitely has some truth to it).

I made no attempt to get on the list and didn’t even find out I was on the shortlist until I received a questionnaire asking for more information. Filled it out while commuting to work and forgot about it.

Didn’t hear back from Forbes at any point and only found out I made it when someone messaged me to congratulate me the day it was published.

Still don’t know who nominated me. Never bothered to ask.

Similar to another commenter, it has been useful given I have a degree from a relatively unknown University in Australia. Maybe it’ll be more counterproductive now? Who knows…

enjeyw··on Arecibo telescope won’t be rebuilt
I’m not convinced it is. The statement translates to:

“I think that the benefit for the community that infrastructure investment provides is so much greater than rebuilding the telescope, to the point that if I had absolute control of the limited gov budget I’d allocate all money to infrastructure.”

That’s debatable, but it doesn’t seem like a logical fallacy.

enjeyw··on Natural Wine, Inherited Money, and the Delusions of the “Future-Rich Millennial”
> Personally, it kinda grates on me.

Presumably there are (relatively) straight-forward solutions to this issue no? For instance; accept the money from your parents, invest it into an Index Fund without touching it, and when your parents do pass on, donate the inheritance to GiveDirectly or whatever charity you deem worthwhile.
