Ask HN: Where can I find mentors for CS-adjacent things?
Hello!
I'm a pretty highly motivated high school student and I've started doing projects and learning theory that would significantly benefit from mentorship to clarify things/answer obscure technical questions. Where can I look for someone that might be willing to help me out?

Shoutout to [rust mentors](https://github.com/RustBeginners/awesome-rust-mentors) for doing something similar but I'm looking for a more general site or social scene where people volunteer their time (ideally with an opportunity to give back and mentor someone else so I don't feel guilty)
Thanks that blew my mind, had to go tell the folks in the next room. Cool perspective. Where can I learn more?
I like my gas stove. It heats my food well and quickly. It’s not very expensive to operate.

I hope my next house has similar functionality.

Questionable decision making. Why not use Go when minimizing runtime dependencies is first priority? I’d probably just have cleaned up the Ruby code and used something like Ruby-Packer to create binaries. When typing is so important why not use rbs? Makes no sense to me.
Highly recommend watching This is Pop on netflix, specifically the T-Pain episode. They do a deep dive on Auto Tune in the industry and T-Pain's relationship with industry musicians. Turns out he's a phenomenal a capella singer.

As everyone has already pointed out, the Cosmic Microwave Background Radiation is as close as you can get to the Big Bang.

But to the larger point, these galaxies were suspected before, based on Hubble work. You see, the COBE satellite from 1989 to 1993 mapped the microwave background radiation very precisely (two of the Principal Investigators on COBE won the 2006 Nobel Prize in Physics for this work). And they found that while there are minute fluctuations in the radiation, those fluctuations are measured at the parts-per-million level of difference. But the Hubble has found that the farthest back galaxies it could see were some of the largest and most massive things ever witnessed. So we had this gap between 'everything everywhere is the same to parts per million' and 'there are some supermassive galaxies' and so the Webb telescope was specifically designed to find the things that were redshifted so far they were out of the visible spectrum (so Hubble couldn't see them) but not so far that COBE could see them in microwave: in the infrared spectrum that lies between those two, that's where Webb is supposed to focus and help us understand how these galaxies form.

Because this question of what happened between the CMBR and the visible light range is the biggest question left over from Hubble, so it is what drove the design of the Webb. This is how astronomy has worked for centuries: you build a new telescope to answer some questions, but that leaves you with more questions, so you need to build new telescopes to answer those questions, GOTO 1. That's what's been happening ever since Galileo looked through that telescope at Jupiter all the way back in 1610.
As employee #36 I lived through some of these things first hand and definitely agree with them (I think we were over 200 people when I left).

It was painful going through the enterprise focus transition along with a nonsensical reorg imposed by the aforementioned Big Tech VP. One day we had focused platform-specific teams working on satisfying customers, the next we were moved to cross-functional feature teams and focused on enterprise features that (from our perspective) no one ever asked for.

I also felt the sting from mediocre engineering managers. I remember sitting down with Tracy and Ralph at Uptown Bar and giving them both barrels on what I thought of several managers. To their credit those managers weren't working there very long after that conversation.

IIRC Ralph asked if I wanted to move to being a manager and I declined but in hindsight I think that was a mistake - we needed good management in engineering more than we needed my code.

Another thing that hurt us was hiring a bunch of PMs. Most of them were condescending, ignorant, or both... but suddenly they were telling the engineers who had built everything what to do? IIRC we could have cut that department down to two people with no loss.

The leader of this product team was a manager that just didn't seem to be doing his job, only pushing paperwork and giving scatterbrained presentations. I never did find out why he was kept on so long. I think I very cheekily asked Tracy one time which of his relatives worked at Y2K or Sequoia such that he couldn't be fired because it was clear everyone in engineering was fed up with his nonsense. I'm pretty sure at least several top engineers quit due to that guy specifically.

Either way I don't regret my time at PlanGrid. It was a great team and I'm proud of what the team did and what I did.
OK well then, we'd better not do anything about it! <s/>

I don't think this is strictly true. Oil production is not fully fungible due to all kinds of issues including sanctions and production capacity.

But this is also a strawman - this isn't saying "we should shut them all down" or even begging that question.

At a minimum it's saying "there were people and companies who intentionally chose to mislead the public on a potentially existential issue - perhaps there should be some reckoning for that?"
Go has an excellent standard library for cryptography primitives with well-established best practices. It was designed and is maintained in a principled way that likely appeals to more cryptography engineers. Also see this answer by one of its maintainers:

https://www.reddit.com/r/crypto/comments/zukgfq/comment/j1l2...

Some additional reasoning why having a strong standard library is important:

Dark matter is the umbrella term for the observed discrepancies. MOND is one possible possible explanation for DM. The paper you linked doesn't compare MOND to DM, because that doesn't make any sense. It compares MOND to ΛCDM which is a competing explanation.

So there really is just a careful balance between salesperson role and community participant role (for good salespeople who understand the balance, disregarding the salespeople who just sell and push). And as long as the community/employer ecosystem doesn't start to test those roles too hard, everyone is happy. Sigh that sort of depresses me, that this sort or relationship tends towards instability as time -> infinity. At least we have finite lifespans

> As you say, you _can_ be an authentic community member if you happen to have something to sell to the community - but if your _reason_ for joining the community is to try to sell to them, that is highly unlikely.

Yeah, this feels like the problem to me. The unlikeliness of it is why there is such a distaste societally for salespeople, causing the blindness to the least evil type of sales person.

I sorta figured this out in another comment too. Thinking about the corporate mechanisms, sales hiring managers would need to weed people out properly based on them recognizing this balance. And on top of that, you would need a pool of applicants who actually have the personal investment in the community in the first place, or the potential to become personally invested. Very unlikely! Or so it feels across most sales hiring interactions.

Am I understanding that paper correctly that their suggested solution to explain the Bullet Cluster using MOND is too introduce an additional kind of matter which can not be detected on earth and doesn't interact with light (namely sterile neutrinos)?

I think requiring proper ventilation would be enough to force most installations to choose electric because it will be the least costly option.

The house I own came with a gas stove and a vent that vented inside (the previous owner said it vented outside...). It cost nearly $800 to have it properly vented to the outside. I think the vent itself was $400 but that's based trying to figure it out which model we had. The thing I do remember about the vent is that it has 3 settings and only the highest goes above the recommend CFM.

If the installation of a gas stove is going to entail an addition of $800 to $1200 (could be cheaper for a builder), why would they choose this option unless they knew they could charge a premium for the home?

But I do concede the elimination of gas stoves is beneficial for the environment as well; and, imo, is a much better argument than the manufactured moral panic around asthma in kids.

It's got its advantages, but they had an opportunity to solve one of JS's biggest weaknesses—the terrible standard library. And they just... didn't.
The "observable" universe is about what we will ever see in the future, rather than about the past. If you waited around for billions of years, you could watch those early galaxies evolve.

There might be galaxies even further away, but you can't ever see them, not even in theory. The light from them will never reach us because they flying away from us further than the speed of light.

The CMB isn't really about galaxies. We know there won't be any galaxies past the CMB because galaxies couldn't have formed before the CMB was emitted.

In theory we can "see" past the CMB using gravitational waves. (There was a thought, in fact, that we'd already done that, but that appears to have been faulty.) The CMB is just kind of a practical limitation rather than a fundamental matter of spacetime: you can't see because it's too cloudy.

The question of whether galaxies beyond the observable universe "exist" is kind of a matter of metaphysics rather than astrophysics. As an astrophysicist, you basically just say they don't exist and you're done with it. But if you want to know where the universe "came from" (whatever that turns out to mean), you try playing around with notions like "our universe is an observable sub-part of a wider ensemble, which we'll never detect, but here's a pretty set of equations which explain our universe in terms of it".
Your critique assumes that the goal of scientific writing is to be intelligible to lay people.

In truth, the entire weird and crufty vocabulary is simply a common set of placeholders that makes it easier to grasp research, because the in-group learns to understand them as such.

I'd like to hear from anyone who has issues with typescript as a build tool, either via `tsc` or an integration via something like `rollup`, what issues are you having? How often?

I have not found, even in really large projects with thousands of files, that its been an impediment to anything.

My general disposition is the whole "anti build tools" moment is a bit overblown in practice, and I'm always searching for valid counter evidence of persistent issues that can't be easily overcome.
The universe is 13.7b yo, but due to acceleration of expansion, if you could "teleport", it's actually currently 93b ly across. So we're already in a bubble within a greater universe that we'll never be able to escape even if you could instantly reach lightspeed right now, and due to the expansion continuing to increase, the fractional size of this bubble relative to the rest is shrinking. Faraway galaxies that are "currently" on the edge of the bubble but expanding away are becoming forever unreachable as you read this.

The free tier shutdown was definitely not the best marketing. Their prices are steep in a docker/kubernetes world. They could have had at least left the free tier for Ruby projects as it’s their origin.
Thanks, but I'll just use a proper keyboard.

Interesting that even Apple chose the D key for "delete" and the action is "forward-delete" and not Backspace, though.
in gdbms, there is the concept of "predefined joins" where you define a relationship edge that directly connects 2 nodes, i don't know how these guys do it, but at least in neo4j that's the concept

edit: just saw their blog, they ask you to define a "rel table" and that has to define all the joins and they load it from there
I agree on the "error messages are hard to follow". A lot of times when you have an error it doesn't clearly communicate "hey it should look like this" (something Rust does soooo well) and instead says something like "types or property A incompatible with property B that is incompatible with X and not Y and ....". It basically just explains the nesting but is so hard to actually make sense of or how to solve it.
Sorry for the nihilistic view, but sadly, we’d all probably be better off if we voted randomly regardless of the candidate’s party membership. Otherwise, we vote for the candidate that gets the most air time from our party of choice or issue de jeur, which is usually the most corrupt candidate.

Till voters wake up and realize that the problem is not with other people’s representatives or the other party, we are doomed to repeatedly make the same mistakes.
> Rather it's that the rate of expansion of the universe is accelerating, so that we're moving away from parts of it faster than its light can cover the distance to us. It will never reach us.

It's actually even worse than that. Because of the accelerating expansion of the universe, over time the part of the universe that we can observe will get smaller, allowing us to see less and less of it. Eventually, all that we'll be able to see is our own local group of galaxies, where gravitational attraction will win out over the universe's expansion. However, this won't really be a problem for a few billion years.

~$60k for a specialized tool makes sense

However it's clear we are years and years of development away from this actually being relevant over conventional tools.

What you describe is it what the models can do today, but what they might be able to do with more work. It is possible conceptually now, but getting it to work on a product or MVP level - still risk there.
Nahh man, I reckon if you're shoe-horning vaccine stuff into an FTX story you're a bit more antivax than you're letting on, and it sounds like you're out to get more people on your side. The guy took a significant blow to the chest just before it happened, the odds that a vaccine was responsible are about the same as it being caused by what he ate for breakfast, the flavour of gatorade he was drinking or the way he laced his boots up.

I don't know if this instance qualifies as one, but I think its fair to say that cosmology is the one domain of "fundamental" physics where "discrepancies" or question marks keep piling up and not really resolving.

It the pattern of previous science revolutions repeats, there could come a point where reinterpreting the large existing body of knowledge using a different paradigm would explain an number of "oddities" in a more economical way.

I don't know if this generation of telescopes will get us there but it feels that this is a plausible outcome over the next 1-2 decades. Which would be very exciting :-)
Yep. That is all correct.

It's conceivable that we could observe gravitational waves during that period before the CMB, because they're not blocked by the un-recombined electrons and protons. If we ever get there, it could help explain the small variations in CMB from place to place. But that's a long way off.
Maybe that should be retronamed to Keep It Simple Smart. ;)
It's not. Moderated public feeds are useful (way too easy for stuff to get offtopic, even if it is not technically spam or abusive), that I agree on, but if I subscribed to someone I should be able to get their posts, regardless of what random moderator thinks about them.

Especially that moderation and "for free" usually ends up with power trips being actual payment to the mods

> as long as there are other servers you can feasibly switch to if you don't agree with their definition of "spam".

Not that simple. If server A doesn't like X (not even abuse, might just not like topics that are talked about there), server B doesn't like Y and server C doesn't like Z your only choice is your own instance and that's far more effort than most want to go thru

Most reactors in service operate at a constant load, and don't vary output according to demand. Certainly in the UK they do not. Sometimes reactors are operated for extended periods at reduced load for various reasons (eg: to conserve fuel and extend the time before a refuelling shutdown is required), but they don't vary output day-to-day.
You are technically correct that you don't truly need jQuery to build sites today.

That said, there's still useful jQuery libraries and example code out there, and it's still a good experience to figure out the basics, if only as an exercise to figure out how one library works. If OP is trying to get a first web-developer job, there's fairly good chance that they'll encounter some legacy systems that use it for a first job. If this is anywhere near accurate, the usage today is still surprisingly widespread.

Although note that avionics fall under the "transportation" exemption, and RoHS does not apply.

That said, the supply chain has moved largely towards RoHS compliance, so some avionics inherit that for supply chain simplicity. Some don't; there's a cottage industry reballing BGAs from lead-free to leaded solder for aerospace applications.
Is this "cancer deaths per person per year", or "cancer deaths per detected cancer"?
I have seen this IC vs team aspect discussion before, and it definitely has merit. However I am starting to question if it's even worth it for larger codebases used by many devs, which is why I wanted to pose this question.

Can you think of cases where it's actually prevented a bug where that piece of code is unit tested? I have been actively monitoring for this to happen, but so far not seen it (I think I have seen it catch a couple of bugs for code that did not have unit tests).
Projects like this is why I come to Hacker News.
