>And once again HN claims to be rational...

Remember that the people here are tech focused, for the most part. Few, if any, have any experience at all with power generation, let alone nuclear power generation.

When was the last time you saw an intelligent, rational, and unbiased discussion here about something that you had intimate knowledge of? I've worked in higher ed for decades, and sister let me tell you, the threads on here about higher ed are full of very short-sighted/anecdotal/ignorant statements.

I just have to assume this thread is the same as that. It's easy to have an opinion about something when you don't know very many details.
I love the innovation going on in the search space lately. Defaulting to a chat interface adds a lot of burden on your users (need to formulate a longer query) and yourself (need to nail the response in top1). Personally I think there's enough cool stuff in your grid/list views to make it useful without trying to shoehorn this into a chat UX.
Is there a problem with CoffeeScript? I'd used it once and enjoyed it.
I used to feel this way too, but I found sudoku varients a lot more enjoyable. If you look up the YouTube channel "Cracking the Cryptic" they have a lot of different ones.
the relevant question in that in that case is: what would your average score be with and without prep over say 10 tests
> The same can't be said for, say, hydroelectric dams. Those are arguably even more dangerous than nuclear plants.

Imagine a hydroelectric dam "Chernobyl".
At least the mid to longterm consequences would be softer.
I think they would have figured out a few years later how to rebuild everything.

Chernobyl (>35 years ago) on the other side is still buzzing and the rebuilding of the sarcophagus is ongoing and will be for a long time

As someone who’s a home networking enthusiast, and has too much Mikrotik gear at home, I can kind of understand what they’re coming from. RouterOS has the usability of “enterprise-grade” network equipment (meaning it’s arcane and non-intuitive), but at the same time has lots and lots of half-working features.

I simply cannot believe how terrible their IPv6 support is (still no connection tracking!), and plenty of weird glitches, etc.

But! Their hardware is very reasonably priced, and an excellent gateway to “real” networking equipment for the hobbyist. It’s unfair to compare it against Juniper and the likes: yes, it’s much better, but yes, the products are also 10x - 100x as expensive.

While everything that’s done in RouterOS can also be done under vanilla Linux, I buy Mikrotik precisely because I don’t want to build a custom Linux router. I want something that comes with a GUI, and I won’t have to spend too much time setting up.

Having said that, I would absolutely kill for an “escape” Linux shell. I know that RED supports ECN in Linux, please allow me to use it!
My own anecdotal experience confirms that sat and act tests are very studiable. Honestly even more than average tests just because there is so much material available to study with.
There are discrete forms of “gradients” which generalize classical CS concepts. Submodular optimization, for example, covers many algorithms that search for optimal configurations of discrete sets, and it does so by arguments that are analogous to convex optimization.
im seeing a lot of "my router" and "my computer" threads so its probably worth it to say this isnt for your home network. Mikrotik is targeting larger customers with a product that handles offloading to the ASIC's on the board, which is far more performant and scalable than COTS ethernet cards or the onboard gigabit.

the reason you would slap a router card in your rackmount server is because its an IOMMU passthrough to a k8s service load balancer or straight up just openstack and the push toward hyperconvergence. the switch is already virtual inside the kvm on openvswitch (has been for a decade now), but the router is still hardware and this product aims to solve that problem.
"I can't wait to be able to buy stuff like this or "cow-free milk" in the supermarket..."

There's plenty of cow-free milks in the supermarket already: they're called nutmilks (ex: soy milk, almond milk, oat milk, etc). They've been around for decades.

The main thing I'm waiting for are good vegan versions of sharp cheeses like sharp cheddar and blue cheese. A good vegan smoked gouda would be nice too.

I've yet to taste creamy vegan ice cream that's on par with the best milk-based ice cream, but at least vegan ice creams can be pretty good and getting better.
> can't we use many different things for nuclear though?(and uranium is just the most efficient?)

Strictly speaking, U-235 is the only fissile isotope of any element that is found in any significant amounts in nature. However, breeder reactors can also be useful. The only two starter points I'm aware of in nature for significant energy extraction are U-238 and Th-232. U-238 breeder reactors are politically complicated because they can relatively easily be used to generate significant amounts of Plutonium which is usable in bombs.

Th-232 reactors have technical hurdles that are probably surmountable; specifically the neutron economy is significantly tighter than U-238 breeder reactors (this is why you often see liquid-salt reactors proposed for Th; chemically separating the decay products gives plenty of breathing room in the neutron economy). The U-233 it generates is also usable in bombs, but since it will tend to also generate U-232, which is both difficult to work with and easy to detect, it's considered less of a proliferation risk.

This all misses my original point though. At any point in the first half of the 20th century we had enough oil to last us for centuries at then-present day usage. Yet here we are.

Then why do the rest scores correlate better with college performance than other factors?

If SAT scores also correlate well with, say, income, would you then accept that they actually reflect something important in the real world?

Trump got banned from Twitter for inciting violence.

India leads the world in violence to support traditional values (having a big population is part of the reason) and there is a lot of concern internationally that Hindu nationalists will be violent towards minorities.

I think we should all be respectful of other people's religious beliefs but it is one thing to say something blasphemous and another thing to encourage violence on or off social media.
For our hardware product, no; for our software product, yes, from time to time.

The hardware product is a network security device that essentially works as a black box, with limited inputs and outputs. It requires so much domain expertise that the small group of us that work on it take an incremental approach both to feature development and to bug fixes, with a fair amount of design review, code review, discussion, prototyping and PoC, etc., before moving to actual testing.

Most recently, I've tended to do the bulk of the development and one of my colleagues the bulk of the testing. When we find errors, there is a lot of screen sharing to review code and logs, determine the best way forward, etc.

Our build process generates ISOs with several layers of security, from completely locked down release instances to a permissive mode with a development account for the privileged access necessary to run onboard diagnostics.

The caveat is that one of our main customers is a security agency with complementary expertise, and they tend to beat the bejeesus out of it.

Overall, we take a similar approach to our software product (design and code reviews, much screen sharing, discussion between development, marketing, and senior management on what it should do and what it should look like, etc.), but at some point it gets turned over to QA. I wrote above that our QA resource was full time from time to time, because when they are not doing QA on the product, they are doing market research and analysis, developing marketing strategy, etc.

From on QA PoV, one major the difference between the two products is audience: The hardware product is used by domain experts to do very specific network segmentation and data transfer; the software product is intended for general use by non-IT corporate users - it's a web application for integrated risk management and compliance reviews.

We consider ourselves competent to fully test the hardware product we've updated, because its functionality is essentially binary: either it works or it doesn't, there aren't a lot of variations in use case, and we are best positioned to determine how it should work and whether it is working.

We don't consider ourselves competent to fully test the software product, because we are a) too close to it, b) domain experts, c) not typical users, and because d) we have a lot of experience with a lot of different software.

Our users are often people who mostly use browsers, and occasionally office products. They may be domain experts, but their domains are far from IT (especially the physical security people).

Our QA person is excellent at getting into their shoes, so to speak, imagining how they might approach things, and findings both bugs and ways that our designs and GUIs and UXs lack and don't help users get to where they need.

Having someone with that external perspective is invaluable. Having them be full-time when in QA mode helps us move quickly when we need to - they are never the bottleneck, and anything released has been thoroughly beaten up.
can't remember where I heard this but the advice was basically this: When pitching your idea, and generating excitement, ask for money (or a commitment) on the spot. There's a big difference between saying you'd pay for something, and paying for something.

The flip side is that sometimes it takes awhile to build the perception of value, hence free trials/freemium models. Get people hooked, then ask for $.

There are many ways to be successful (and even more ways to be unsuccessful).

Raspberry Pi Projects: 30 Projects for Any Skill Level
I’ve had extremely frustrating and contentious discussions with maintainers who choose to put forms in front of their issues in their repositories.

It’s bad enough that

1) if I use the project and can’t easily switch from it, I will simply not contribute in any way to the project from that point forward (I’ve filed two issues with Vue.js projects; I will not be filing any more, because they are horribly user-hostile);

2) if I don’t use the project, I will _never_ use the project and generally question why people are using the project (remarkjs).

Having an issue template is fine. Closing issues that don’t follow the template is (mostly) fine. Taking me to an entirely _different_ website to fill in your form and yelling throughout the whole thing that your bug will be closed if you don’t follow the steps of the time warp _exactly_…is user hostile. I get it that there are entitled users of projects. But by disabling issues or putting a form in front of issue reporting…you have told me that you don’t actually _want_ users, so I’m happy to oblige.

I was looking for an excuse to try Svelte anyway.
> it is reasonable to wonder about the psychology of opponents of standardized testing

It is, at its core, a fear that testing largely reproduces the status quo. If one accepts the idea that there is an intellectual elite who constitute the highest strata of society, and that their gifts are innate and heritable rather than trained, it follows that social mobility is pretty much dead. It is a bleak vision.

Personally I think there are different problems that are much bigger and woollier which keep people from non-elite backgrounds down, regardless of test outcomes. The structure of the education sector and employment more widely. Expectations about life and the distribution of rewards etc. We rarely have good quality, nonpartisan discussions about these things which I think pushes people to take views which are instrumental rather than informed.
The US Navy has built hundreds of nuclear reactors in much shorter timeframes. There's nothing intrinsic about nuclear that demands such long builds. It'd need to be done at a societal level with some sort of standardization and mass industrial process. The French more or less did this for their nukes for instance.
And it has to be a particular two. It's a very situational bonus rather than proper graceful degradation.
I've been in jobs where was less was expected of me than I was capable of delivering and, more often than not, jobs where more was expected of me than I was capable of delivering, at least for any considerable length of time without burnout.

Both were difficult. I like to think that if I had one of the lower effort needed jobs now that I would find other useful things to do like the author mentioned. At the time I mostly read books or played video games with other staff when I was done with my work. It was nice but a bit frustrating because I would go home and feel like I had already read and/or played video games so I didnt have fun things to do after work.

Absolutely a problem from the top of the hierarchy of needs but still a problem.

Ok, a decent set of targets, certainly for starting out with.

Did they reimplement the entire C library? Added a backed/port for an existing library?

Thanks for the interesting link. However, based on the paper, it seems like a "30 point increase out of 2400 points" could be significant. The study says:

"A survey of NACAC-member colleges unexpectedly revealed that in a substantial minority of cases, colleges report either that they use a cut-off test score in the admission process or that a small increase in test score could have a significant impact on an applicant’s chances of being admitted." (p. 2)

The paper later notes:

"These results indicate that in some cases more than one third of postsecondary institutions agreed that a score increase on the SAT-M of 20 points, or a score increase on the SAT-CR of 10 points, would 'significantly improve student’s likelihood of admission.' This proportion tends to rise as the base level of the SAT score before the 20 or 10 point score improvement rises. This is especially true for the more selective institutions. At lower scores on the SAT scale, a small score increase does the most to improve a student’s chances of admission at less selective institutions; at higher scores, the same increase appears to have an equally large or even larger impact at more selective institutions." (p. 19)

The graphs on pages 18 and 19 give more detail.

The paper also notes that "The College Board gives a specific example of a use that should be avoided: 'Making decisions about otherwise qualified students based only on small differences in test scores'." So it appears that up to a third of the institutions surveyed are not following this guideline. It would be interesting to know who they are.

I agree with your comment about rich kids gaming GPA, essays, and extracurriculars. Daniel Markovits addresses many of these points in "The Meritocracy Trap". Since I don't see how you can prevent gaming GPA, essays, or extracurriculars, given the alternatives, you're probably right that the tests may be better in this respect.
However, on that note it's worth taking a moment to look at recent OpenSSL bugs and compare LibreSSL and see that unsurprisingly (to me anyway) the OpenBSD people did not magically fix the bugs in hairy C code. Once Libressl had taken out the unnecessary stamp collecting from OpenSSL (crypto algorithms you will never need, feature switches left over from experiments a decade ago, etc.) it did not in fact evolve the rest of the codebase as much as you might imagine.

If you've found a bug in pre-fork OpenSSL core material (not the stamp collecting), chances are that it still works in all the forks, none of them have the beyond wizard level competence to rewrite somebody's micro-optimised ECDHE implementation in a way that non-wizards can review, so even if they replaced it they'd just be swapping possibly-incorrect wizard magic for different possibly-incorrect wizard magic and what's the point of that?
You want to do a calc test instead? I wouldn't even complain. If the average leetcode is hard for someone they're probably going to suck at even just integration e^z over the unit circle showing your work.

somewhat implicit in "customer willing to spend money to solve the problem" is: are they willing to spend time to solve the problem right now (integrating your software into their application, migrating to your app, etc). Often times customers will have the problem you can solve, but it's far down on their list of priorities.
A bigger reason that FreeCAD isn't as good as it's paid equivalents is the lack of reliable undo (as well as a few other problems caused by the same issue).

This doesn't stem from the UI, but from the handling of core CAD data structures. For instance see the topological naming problem and the constraints it imposes on designers[0].

Realthunder3 has a branch that helps move a lot of this forward.

>"If someone seems irrational, it's because you don't understand the person" "Thats not true, because I didn't understand why somebody did something, so he must be irrational."

Who said I didn't understand why the guy shot him? I certainly didn't.

>To answer hard questions quickly like that, your brain has a trick: it doesn't actually answer THAT question, but secretly gives the answer to a different question, that merely looks a lot like the original question. In this case, I suspect your brain is actually answering: "If I had an altercation on a crowded station, and somebody pushes me to the ground, WOULD I slowly get up, draw a gun, and shoot the guy 14 times?" The answer is no, so the 'answer' to the question is this guy being rational is also 'no'.

Uh, no that's not what I did.

In this case there isn't.
I vaguely recall a question on the Duke University application about what assistance you received with your college application efforts. (I can’t remember if test prep was included specifically.) I’m sure that some people lie by omission, but maybe asking this question is better than not asking it.
It's clear the SAT/ACT has predictive power for highly-selective colleges, such as MIT. And therefore, they are valuable for these colleges – especially for the Math scores as MIT suggests. The value of SAT/ACT scores decreases as selectivity decreases or as math abilities matter less for admission (e.g., liberal arts programs).

Here are some related points:

- Harvard considers roughly 4 in 5 applicants to be academically capable of doing the work at Harvard (about 50,000 applicants of which Harvard only accepts 2,000). This data is pulled from their court documents, and my team wrote about it here: https://writingcenter.prompt.com/posts/strong-essays-increas....

- This means that most applicants at highly-selective colleges are very similar academically. Colleges are mostly just using grades, academic rigor, and test scores to determine whether the student will be able to succeed doing the work in college. Absent other information on academic preparation (e.g., not having access to AP/IB classes), the SAT/ACT score can be a critical signal of whether the student can do the work. Students with well-above-the-bar academics are admitted at a 3x clip to those just above the academic bar. But other parts of the application (e.g., essays, athletics) can have a much stronger effect on admissions chances (e.g., a strong personal score, much of which is essay-related, can have a 10x increase on admissions chances).

- Math SAT really is highly predictive of math abilities. When I was with McKinsey, we asked for applicants' SAT scores because it was highly predictive of people succeeding at McKinsey. People hired with scores below 700 struggled to succeed analytically. So, McKinsey used 700 as a bar. MIT is roughly doing the same thing here. Other colleges do this as well.

- Outside of highly-selective institutions, the SAT/ACT can have less predictive power in student success in college than other factors (e.g., GPA). There are a bunch of great analyses at fairtest.org that looks at these exams - e.g., breaking scores down by race.

So overall, we tend to give weight to what we know and what data we're looking at. Most of the SAT/ACT analyses out there are looking across all students. Here, MIT is looking at just their proportion of students. So, both things can be true – the SAT/ACT may not be a useful predictor for the vast majority of students. But scores can (and do) matter for the highest performers, the approximately 1% of high school graduates attending the most selective colleges.

And as MIT states, a perfect SAT/ACT score doesn't matter all that much. All they're using the scores for is to provide an indication of whether the student is above their bar for being able to do the work (e.g., not failing multivariable calculus).

Note: I did go to MIT – some of you may think this is relevant. I also run the largest college essay coaching company globally, Prompt.com. So I've spent a lot of time understanding college admissions.
