> but the original poster does not seem to imply that overrepresentation is the reason we don't focus on Asians

They literally wrote that though:

> For example, no discussion is given to the fact that...Similarly no discussion is given to the fact that...There is no discussion on the...Why? Because Asians are "overrepresented" and serve as a counterexample to the narrative that systemic discrimination can't be overcome with hard work.

> I also don't believe gay people are underrepresented in higher education, relative to their overall population in the United States, so I don't find that part of your argument compelling

I didn't say they were overrepresented in higher education. This thread isn't specifically about the Harvard problem. It's about the parent thinking that "woke" people only care about discrimination against black, latino, and gay people.

I'm saying that the focus is on those groups because they have typically been the most effected by discrimination. If Asian people are overrepresented in what society might call successful careers, then I think it absolutely makes sense to focus on groups that are underrepresented.

It's also not at all true that Asian racism is ignored. There was huge outcries when Asians were being assaulted randomly.
That's a tautology, isn't it? If the persistence engine you're using doesn't support a feature—no matter what that feature is—you'll have to fill in the shortfall somewhere else, such as the app layer.

I'm just saying if you have the option, if the engine does support the feature, and the solution is a good fit for your problem, you shouldn't shy away from it just because some other engine doesn't support it.
Interesting language/script.

Are there any other comparable alternatives?

Would Node/TS-Node be a suitable replacement with a few shell helper functions?
Erotica isn't a synonym for taboo, it's anything arousing. I guarantee you no matter how well accepted public sex is in your putative hunter gatherer society, some onlookers are going to get a bit hot and bothered. We're not talking a visible nipple here, we're talking actual coitus or explicit depictions thereof, and if you're refusing to consider that to be erotica then what does the word even mean to you?
I don't recognize the legitimacy of that concern. It's a two-way street and ultimately a wash on a personal level. If you demand that I seek permission I've now also lost bodily autonomy, while at the same time unfathomably increasing the cost of any sort of genetic research. It's a recipe for scientific and medical paralysis where everybody will almost surely lose.

I view it much like abortion. Does a fetus have any recognizable interests? Perhaps. But nature makes it impracticable to give both mother and fetus bodily autonomy unless society changes the balance of power. While many societies will choose to limit abortion, I frankly find it extremely unlikely that any will choose to give relatives--even close relatives--a veto power over another's genetic disclosure. At a societal level the costs are clear and the resolution of the dilemma of incidental genetic disclosure becomes a non-issue. Rather, IMO the concern about relatives is just a rationalization for doing nothing while entertaining excessive anti-corporate, anti-capitalist, anti-government paranoia. Moreover, if someone can provide any concrete negative externalities (i.e. beyond the freedom to be paranoid and indignant), societies can address them in particular, much like they did by prohibiting exploitation of genetic data for health insurance, employment, etc.
Is this really a shell scriping language? Hush isn't an interactive shell, nor does it compile to a common shell script. The only way to run these scripts is to install the hush interpreter and run the script through it.

Isn't that just a normal scripting language? What's the real benefit of using this over Node or Python? I suppose the syntax is more aesthetically similar to shell scripts... but I don't exactly see that as a plus.
It’s since been released.
Are you required to tell your employer if you're moonlighting or doing other paid work? I'm not.

Does your employment contract (or the closest thing you have if you work in the US) specify 40 hours a week? Mine doesn't. It says I need to be available during "core hours" which amount to about 17.5 hours a week. It also takes about half a page to basically say "you have to get your assigned work done on time or you may face disciplinary action." If you're available during core hours only, and your stuff gets done, you've fulfilled your end of the bargain.

I've worked placed where you have to have your ass in a seat 42.5 hours a week minus lunch. You can't work there and have another FT job, it's not tenable even for a week or two. But I know a lot of people who either have a FT job and a long-term/large contract position, or two FT W2 jobs simultaneously for months or longer.

Your overly broad "[nearly] universal case" doesn't match the vast majority of the job descriptions I've seen when I was job searching earlier this year. Software development jobs are increasingly remote, and a small subset of those are increasingly asynchronous where they don't care where you are or when you work so long as you get your tasks completed.
Congrats on the launch.

I think this indirectly slowed down the foreverdomains server with the HN traffic.

Since you advertise "decentralized internet" vs blockchain, I'd love to see this also support some more non-blockchain protocols such as Dat (https://dat.foundation/) and IPFS directly. Maybe even Bittorrent and Tor (Onion router).

It may already do some of that, I just couldn't tell from your wording.
Do you think Wasow would have picked that moment to promote his research?
Some other interesting libraries I've seen along these lines:

- Sokol (sokol_gfx in particular): https://github.com/floooh/sokol

- wgpu (see wgpu-native for the C API): https://github.com/gfx-rs/wgpu

It kind of seems like graphics abstractions for modern hardware are getting pretty "figured out". There are wrappers that work for most DirectX/Metal/OpenGL applications so they can run just about anywhere, and new 2D/3D applications have a lot of accessible/open-source options to build on top of. Projects like Mesa's Zink will centralize the burden of maintaining legacy APIs away from hardware manufacturers. Valve's Proton is making waves. WebGPU is on the way.

The future looks bright.

They purposefully had to make it this vague so it could stand even the minimum of court scrutiny... unfortunately for them, the wording is impossible without explicitly stating what the purpose of the language of the bill is actually for, so...

>Moderation is a hard issue.

Honestly, Elon Musk along with the team at OpenAI using things similar to what has already been accomplished with GPT-3, can make a real improvement in AI based moderation, at least in terms of being able to understand the differences in messages and their meanings. Everything from hate speech to terroristic threats to suicidal messages can at least be accurately measured and scored by AI to move up to a human moderation queue. AI based moderation in a transparent way would really help the current opaque, biased, politicized moderation that currently exists on twitter and most other large platforms.
Tell HN: Amazon.com is limiting purchases of Audio CDs to four-per-week
According to customer service, all customers are limited to buying four Audio CDs per week from any seller, in any combination, on Amazon.com.

This is not a per-title nor a per-seller limit, nor is it related to Amazon Prime or FREE Shipping or whatever. It's across all titles and sellers, in any combination (including 3rd party sellers), with any form of shipping, Prime or non-Prime.

Talking with customer support over the weekend, they claimed it was an error and would be fixed today, but as of this posting, the four-per-week purchase limit is still active.

The specific error message (during checkout) is:

There was a problem with some of the items in your order (see below for more information):

You have reached the purchase limit for this item. We have changed the quantity to the maximum allowable.

If the quantity has been set to 0, please delete the item (below the item details) to proceed.

Yea that's exactly the argument behind Bitcoin as a store of wealth - any other currency can change their inflation schedule, Bitcoin will not.

It is basically impossible to change bitcoins supply because to change it you have to get at least 50% of the community to agree and that's not happening any time soon, if ever. You can fork Bitcoin but that doesn't create any additional wealth, it's just making more bits that aren't Bitcoin. Some people may value them but they won't have the value of Bitcoin.

This is quite the rabbit hole but according to some background it links to a number of interesting problems, for example phase transitions in spin-glasses in physics. The wiki page on spin glasses is a good place to start, perhaps. Here's more on background:

http://assets.press.princeton.edu/chapters/i9917.pdf

"These are all examples of what are called combinatorial optimization problems, which typically, though not always, arise from a branch of mathematics called graph theory...What have spin glasses to do with all this? As it turns out,
quite a lot. Investigations into spin glasses have turned up a number of surprising features, one of which is that the problem of finding low-energy states of spin glasses is just another one of these kinds of problems. This led directly from studies of spin glasses to the creation of new algorithms for solving the TSP [Traveling Salesman] and other combinatorial optimization problems."

The first reference in the original Kahn-Kalai “expectation threshold” conjecture (as linked in the article) is this 2005 Nature paper, "Rigorous location of phase transitions in hard optimization problems"

https://www.cs.cornell.edu/selman/papers/pdf/05.nature.phase...

> "Constraint satisfaction problems are at the heart of statistical physics,
information theory and computer science. Typically, they involve a large set of variables, each taking values in a small domain, such as {0, 1}, and a collection of constraints, each binding a few of the variables by forbidding some of their possible joint values. Examples include spin-glasses in statistical physics, error-correcting codes in information theory, and satisfiability and graph colouring in computer science. Given a collection of constraints, a fundamental scientific question is how many of them can be satisfied simultaneously."

So... the article notes "each property has what’s called a threshold: a probability at which the structure emerges, often very abruptly."

Here's a short video of a sudden phase transition in supercooled water, which is sort of comparable to a phase transition in a spin glass, or say, the transition from amorphous to crystalline silicon. These things happen at sharp thresholds but have defied first-principles calculation as far as I know about this (which isn't so much, but seems to agree with your latter question re importance):

Perhaps then as a result of this work, your theoretical condensed matter physicists now have new proven mathematical tools to understand things like this?

It's like the top comment, negating "every part" of what someone says. There is more to life - that is, there is life, and people doing good, productive things despite our flaws that seem so absurd.
Thanks! I'll try it with "negotiation" as my other searches brought up stuff that's close but not quite what I was looking for (how it asks for stuff). It sounds like the barrel jack boards might be what I need. I first tried to use a step up module from an 18650 (worked for smaller load), then mini USB (didn't work with higher load). I guess I should look at one of these AC to DC step-down modules.

Most of those are examples of him curating his own life. Not curating yours or mine. If he does, it will be a problem.
The problem is when you follow people for topic X and then they decide to use their audience to talk about unrelated topic Y. I hate that. If I follow someone because they talk about some tech topic, I really could care less what their opinion is on some social or political topic. I found heavy handed use of muted keywords and muting people helps A LOT.
This is pretty cool!

I'm curious, though, why you don't prefer to put your laptop on a stand like the Nexstand?

Of course, your stand would work better wherever space is constrained, e.g. on an airplane.
This looks nice. I'm slightly surprised by the error handling though:

if std.type() == "error" then

It seems (a) a bit verbose and (b) a bit hacky to compare the type against the string "error". I wonder if more ergonomic error handling is something the author is planning.

Elon Musk reaches agreement to acquire Twitter for about $44B
The commenter was probably referring to something more involved than just printing out an html page.
Paranoia is categorically the mental illness that prevents someone from recognizing a friend (and maybe catatonia/coma). But when you say "someone with a serious mental illness" you make a sweeping statement that's just...fucked up and lacking of human empathy.

Moreover, you don't know Kanye. You're not his friend (I'm assuming?) Your comments on his possible friendships are lacking in authority. Actually everyone's comments (excepting the few that have actually close relations/have been affected directly) on Kanye's, Elon's, the fucking Queen's, personality and character are moot and lacking in weight.

I agree that Musk, as a flawed human being with disproportionately large amounts of control in the form of money, might not make the world a perfect (or even better) place with even more, other forms of control. But whether or not he's personable? Whether or not his intentions are good? I don't know any of that, and I won't pretend to.

Oh thank you! A$187 (US$159) is still a lil on the pricey side for me though, for such a short book.
Neat, thank you for posting this.

It is nicely organized, and while most HN readers would find §2 pretty steep, the content of §2.1.4 (Massless particles), §2.3.2 (Geodesics and affine parameters) and §2.3.4 (Massless particles and the Speed of Light) are concise technical answers to a HN FAQ which is essentially "according to relativity, do photons experience no time?". Really frequently "asked". (tl;dr answer: yes, they certainly do, you just write their "time" down differently from that of massive particles. The difference in their time ("affine time") tells you observable things -- for instance the difference in quantum wavefunction phase, or the difference in redshift, just as does the difference in proper time for electron (anti)neutrinos when e.g. leaving the cores of stars or neutron stars, or traversing cosmological distances).

(The missing pieces here are defining a momentum p^\mu = \dot X^\mu where the \dot is the derivative with respect to the affine time, much as the author has actually done in §2.3.3 (Massive Particles), and one of the energy-momentum relations like de Broglie's E = hc / \lambda or \lambda = h / p).

§2.3.5 is another good trio of answers to the HN FAQ about the twin paradox, and I agree with the author that the geodesic analysis is more attractive, namely "both Alice and Bob's paths in spacetime begin and end at the same point, but Alice follows a timelike geodesic, while Bob follows a timelike path which is not a geodesic" (emphasis mine). "Since timelike geodesics are exactly the timelike paths which maximize proper time, the proper time experienced by Alice must be larger than the proper time experienced by Bob. Therefore, Alice must be the older twin." That's really all it takes to resolve the apparent paradox. (However, c.f. "Too Many Analyses" in the excellent <https://math.ucr.edu/home/baez/physics/Relativity/SR/TwinPar...>).

I'm slightly surprised that in skimming the later sections (which I plan to peruse) I did not notice the author discussing the <https://en.wikipedia.org/wiki/Causality_conditions> and the causal ladder discussed therein, and only engaged directly with with (in §3.1.3) global hyperbolicity, although some of the many references in §7 might. I suppose that at 60ish pages the author did not want to commit into turning an extensive set of lecture notes into a comprehensive textbook, which is fine.

Finally, it has been several years since Bob Geroch's "democracy of causal cones" Faster Than Light? paper <https://arxiv.org/abs/1005.1614>, and exposure to that likely would affect the end of this paper's §4.3 ("Tachyons and Time Travel") which deals specifically with faster-than-light.

In fairness all major companies which use a Language extensively tend to invest in all aspects of its well being. Facebook did with PHP, Google hired Guido (and bunch of other python maintainers) and now go.

If your business depends on having a well maintained platform, then it makes sense to invest in it. Shopify should be commended for investing in Ruby. As a former contributor to Rails and Ruby ecosystem in general - IMO I would still choose Ruby for certain kind of work. I write Go mostly these days and parsing random JSON for example is major PITA (so it would be in many other static languages).
The Tesla Model 3 has a base price of $47K. Tesla's gross margin was 33% in Q1 2022. So estimate of manufacturing cost is ~32K (probably somewhat higher as base model probably has lower margin). The battery is 50kwh. Price of a battery in 2021 was $132 / kwh (1). So the battery accounts for $6600 of that manufacturing cost. Even if they could get the batteries for free, and assuming the same gross margin that would drop the manufacturing cost to $25.5K and the price to $37K. So it seems like reducing battery cost is not going to get EV's to mass market. Am I missing something here?

The point is that you can do things like create external processes, pipe them together, redirect output to files, with the same ultra-lightweight syntax of bash etc. Compare that to all the nonsense you have to do in Node or Python to pipe two processes together!

The mindset is that Twitter is somehow a vital utility. There is a model for that kind of business, if that’s what Twitter is. Maybe it is.
Really cool concept. I like the idea of scripting in a "safe" language and then dropping into a command block to do all the system level stuff. It's the best of bash and python, in a way.

I'm not sure when I would use something like this. The verbosity definitely means I wouldn't use it as my actual shell, and I don't think that is the intention. Maybe something like a big service / orchestration script where I need to do all sorts of file manipulation, command processing, etc but there's enough logic and complexity to make it annoying to do in bash.
Crazy to do this for your employer. They wouldn’t piss on you if you were on fire.

Is it important that you own a copy, or do you just want to read it? If the latter, you might try finding it on Worldcat[1], and see if a library near you holds a copy. Note that university libraries will often "sell" a library card to non-students for a relatively small yearly fee, so you might be able to check it out from a local university even if you don't attend school there. Or the local library (public library or university library) might be able to get it for you via Interlibrary Loan.
