Sorry, I assumed you knew my answer was yes.

The law says the answer is yes if the discriminatory effect is strong enough (don’t know what the actual test is), so the answer MUST be yes.
most dockside cranes recapture power on the way down as is.
Craigslist and Backpage "allowed" rampant sex trafficking but I'd imagine the HN community wasn't happy with government shutting down those sections of the internet. FB isn't the one engaging in the discrimination imo.
"if you think the law serves a purpose" Surely it is not controversial here to suggest that anti-discrimination laws serve a purpose and therefore if someone finds a loophole that does not mean it is just fine?

I was just reading in Jalopnik about how Toyota added reinforcement to their minivan to deal with small offset driver's side impacts, and then when a test for a similar passenger side impact was done, surprise surprise, there was no symmetric reinforcement on that side!
Are you sure those bridges aren't counter-weighted? I don't believe I've ever seen a drawbridge that wasn't.

Moving a counter-weighted something-heavy up and down is a distinctly different physics problem (that closely resembles moving it back and forth horizontally) than moving an unattached something-heavy up and down.
Yes, I participated in a clinical trial I only found though Facebook ads. Since clinical trials are very specific on who they are recruiting, it's a great use of targeted ads.

I also once bought soap that was advertised to me on Facebook. It's my go to brand of soap now.

I also read here on HN someone successfully using Facebook ads to target people planning on moving in their city to find an apartment before it reached the open market. EDIT: here it is, https://medium.com/good-signals/apartment-baiting-with-faceb...
There's the horizontal version, so to speak, at https://www.aresnorthamerica.com/grid-scale-energy-storage -- it's running heavy weights up a hill on a closed rail loop to store and use them coming down to generate energy. 78% efficiency is claimed (in the press kit, the web page says "approaching 80%"). It claims to be able to store tens of gigawatt hours of energy.
The amplitude decay certainly would be a very attractive feature for long distance applications. Maybe a gravity wave radar? Do they get reflected? Now we just need to mass produce black holes with the mass of the sun and bump them into each other :-)

> We don’t know that. I imagine if that was true it would have been proved clearly in the last 40 years.

I don't think it was possible before today's microtarget-based internet advertising to use demographic correlates to substitute for banned targeting of protected groups. That it's now much more feasible than it's ever been in the past to target protected groups without facially making protected group membership part of the filtering process puts anti-discrimination legislation in a new position. The past 50 years of case law isn't particularly relevant to this new situation: in 1968, it wasn't possible to filter ads based on a suite of seemingly-irrelevant characteristics so as to accurately re-create banned targeting.

There is some precedent (e.g., Griggs) for applying a "disparate impact" standard to anti-discrimination measures. My argument is that this reasoning, if followed rigorously, will essentially prohibit ad targeting altogether, since every meaningful ad targeting criterion will end up targeting different arms of protected groups differently.

I've seen no rebuttal of this point, either from you or from anyone else.

This post only reinforces my point: GPA hacking is an intentional choice on the part of students, and GPA hacking is not specific to the humanities.

You got nothing out of your humanities courses. The fault was not in your courses but in yourself. You certainly could have chosen to improve your prose, refine your theses, and strengthen the presentation of your arguments. Instead, you chose to GPA hack.

One of the great things about university is that you get what you put into it. Students who choose to invest in credentialism get credentials. Students who choose to invest in an education get an education. You got what you very explicitly chose to get!

The sad irony, by the way, is that your perceived downsides are rare and GPA hacking backfires. I have never heard of a faculty member refusing to write a letter for an engaged student just because they received a B or even a C; however, I've heard plenty of stories about faculty writing lackluster letters or even refusing to write letters for students who were very clearly GPA hacking.

Perhaps most importantly, your original post was written as an indict of humanities courses. In my post, I pointed out that GPA hacking is also possible in STEM fields. Your latest post justifies GPA hacking by appealing to the credential-granting role of higher education. Your argument justifies GPA hacking not only in the humanities but also in STEM fields.

A common saying in education is that cheaters mostly rob from themselves. IMO the same is true for GPA hackers.

One final tangential note about this excerpt from your post:

> With the high cost of tuition (especially in the USA), you want a good return on your investment, not waste your time engaging with the material at the detriment of your chances of success... It seems a far better strategy to maximize your GPA while spending the least possible amount of time on the assigned material, in order to have time to pursue your own interests and be able to more effectively learn the things you want to learn.

Doesn't this place you in a bit of a double bind? If you know better than the faculty, then GPA hacking isn't required because you already know the material. If you don't know better than the faculty, then it's very likely that you are frittering away your time on fads instead of focusing on fundamentals.

If the stacking approach works at all, it must be because it is self-supporting. The material, once lifted, holds itself up.

At first it seems a bit silly that the bottom layers aren't lifted off the ground much at all, but if a tower is N meters high, the average height of each block is N/2, so that's only a factor of 2 loss. (For example, if each block were 1m tall, a stack of 100 of them would be 100m tall, and the average block would be 49.5m off the ground.)

And of course also because concrete is a combination of cheap, strong, and heavy. All of these serve as multipliers for energy storage practicality.

I have a full-time office job running mostly automated systems that rarely need any intervention, leaving me free time to get another full-time job doing the same job remotely.

Technically I am working the two jobs simultaneously which most people would consider a no-no, but the remote job is aware of the local job so that's covered, and the local job really, truly doesn't need full-time attention so as long as the few tasks are covered I don't really see the harm.

I was wondering what the simplest way was to get access to the IFEM so I can swap USD with Tanzanian Shillings. It doesn't seem like any of the popular forex sites list this pair (and they all seem sketchy anyways).

From [2]:

Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO2. Given its high emissions and critical importance to society, cement is an obvious place to look to reduce greenhouse gas emissions.

Ignoring the geographical problems, could using the power source from which energy is stored for these devices also be used to manufacture the concrete, or would you be constrained by the power plants ability to output enough energy intensity to produce concrete?

If feasible to do, then for the geography issue, would the CO2 output from lengthening the trucking route and/or high voltage transmission lines to the storage site possibly overcome the cement issue overall? If the power is ~free, loss in transmission is less important, but then you have to consider the output of manufacturing and installing transmission lines also. Although, perhaps there's spare capacity on some lines.

Actually, once the blocks are manufactured, you can ship them anywhere.

Complicated.

> More importantly, we do not have a clear standarn on what qualifies as a "religion". And for, I think obvious reasons, that is a line we don't really want to draw.

Some standard does and must exist, even if it's not clearly defined. Sincerity of belief is a reasonable benchmark, I think, since religions are systems of belief. Otherwise, nearly any set of axioms can be considered a religion, and if everything is a religion, nothing is.

Putting words into people's mouths like that is incredibly rude, and dishonest.
I don’t argue that ads in the context of housing is illegal.

Targeting specific demographic using protected categories in other areas can be legal too.

As a pharmaceutical company you can target women, men, seniors for targeted medications. As a LGBTQ dating site you can target based on sexual orientation and cis/trans. It is not illegal. Housing and jobs (maybe something else) are covered by specific legislation.

Is a "no pets" policy illegal housing discrimination? Why or why not?

A "no pets" policy, on its face, would have a disparate impact on different arms of a protected group, and so, on its face, should be illegal. I know that "no pets" policies tolerated at this point.

What I want to know is how you or anyone else can justify a "no pets" policy considering the protected group issue I raised above. Is the "no pets" policy just an unprincipled exception [1]?

I see no explanation for allowing "no pets" policies other than "yeah, 'no pets' amounts to illegal discrimination, but everyone does it, so it's okay". That's not a good basis on which to organize a society. Why or why not shouldn't people make another unprincipled exception for ad targeting?

It seems to me that even though the intention of that is discriminatory in some way (and not necessarily against protected classes - the Whole Foods ads might be simply to target higher-income tenants), it's not in fact exclusionary. There's nothing preventing anyone who's not the normal target of these ads from going to Whole Foods or buying those newspapers. In FB's case the excluded audience has no chance of ever seeing those ads.
I keep two notebooks: an A5 one for TODOs that has a specific structure, and an A4 one for whatever, that has no real structure, though I do tend to fairly reliably fill them page by page from front to back. (Both cheapish, nothing fancy - always spiral bound though.) I've found this helps avoid any hesitation when wanting to note something down. I just reach for the larger notebook, find some space somewhere, and write.
Since the whole scientific research machine needs a large number of PhD students and postdocs to perform research cheaply I don't see fixing c) until we solve the funding issue, since the reliance on cheap student/postdoc labor is partly a symptom of lack of funding.

Another point is that professors are very biased in that they successfully completed grad school, probably a postdoc if they are relatively new and then got a tenure track job. They then suggest that you follow a similar track, strong confirmation bias since you see their success and not the "failure" of the 90% who couldn't/didn't find jobs in academia.

I don't think that's what's being suggested. The idea that redlining should be reexamined by the courts every half century or so is what's being suggested. In 2018, courts ought to find its still illegal give facebook a book fine. In 2118? Hopefully we'll be past racism and courts will find the concept obsolete and antiquated. Or they may find racism is common but the tools needed to manage it are different.

Probably not what you're asking, but my side project is working on software projects for a couple local businesses. I work about 12 hours per week on the side at $150 per hour so I make about $7,200 per month.

Having W2 and 1099 income like this is advantageous as well. First, I max out my social security tax at my main employer which means my side income is social security tax free. Second, I max out my 401k employee contribution of $18,500 at my main employer. I then have an Individual 401k with Vanguard where I take about 20% of my profits and deposit that as the employer portion which lowers my federal taxes substantially. I take a good portion of what's left and deposit that in a 529 account for my kids which my state gives a tax deduction for that on state taxes.

My smaller client was just a friend that I met through my kids' school. My larger client I met while studying for a programming certification at a baseball clinic my oldest son attended. A guy who owned a local business saw me with a thick book and approached me with, "Are you in IT?"
Sure, it's just kind of a longstanding concept. If I've found the provision you're referencing (https://news.ycombinator.com/item?id=17790555), then it's a bit disingenuous to assert Faceboot is automatically in its scope, when it's this status as a conduit versus editor that is the very thing we're grappling with.

As has been explained elsewhere in this thread, there are legitimate uses for selecting specific areas at the level of zip codes. Sure, we could hope for Faceboot to do a better implementation based on some intelligence, but that would be asking for a positive action.

But by all means, don't let any sort of nuance get in the way of today's two-minute hate! I'm sure all those racists that are about to hit a speed bump will be deeply reconsidering their views.
A better comparison is advertising in a catholic newspaper. Is that a discrimination toward non catholics? It’s a bit of a stretch.
Again, I don't think they were/are naive. They were "discerning" to borrow your word, in evaluating the challenges of the walk and responses to them.

The other part of your post makes it sound like you believe Santa Claus maintains the authoritative naughty/nice registry; I just don't think the world is so simple.
In most verticals marketers will have a set of ads for different demographics: say gay, suburban, latino, black, Spanish-speaking, etc. Each of those campaigns will have different creative: for example, a real estate ad targeted to latinos will have an image showing a smiling latino couple. I can understand why the marketer would not want to show this creative to white, black, or asians -- given that they're targeting creative for a different group of people. This sort of practice seems fairly benign -- it's not about denying housing, but about targeting creative for different subgroups.

As a gay person, I see this all over the web. Smiling happy gay people buying cars or real estate or whatever. I imagine that behind each of these ads straight people have been de-selected for seeing this ad. But that doesn't mean these advertisers hate straight people or would deny a straight customer. It just means that for that specific ad and creative they were targeting gay people.

No you are wrong.

No, I'm just smarter than you. But that doesn't take much effort. You've admitted loss by switching to insults which we can either continue to trade or you can step up and counter my arguments. You don't have the spine to step up, you're nothing.

While I intentionally kept it focused on "pure React" because I felt that a big part of the "React is hard" sentiment seems to come from how much other stuff gets lumped in with it (and then people feel compelled to learn it all at once), I've been considering expanding it to include some other tangential stuff e.g. API calls, basics of testing... any other ideas would be great to hear!

I don't think the OP is right. The waves LIGO detected lasted for an instant because they were from a fleeting cosmic event - two black holes spiraling into each other. But there's no reason as far as I know that a much more sensitive detector couldn't see waves from more mundane, longer-lasting events.

Though - at that point, why not just send EM waves? They travel the same speed. Maybe gravitational waves could penetrate anything, if you're willing to spend planetary amounts of energy to do it?

Bras and strollers are not essentials for living. Housing is. That's why Fair Housing laws, and not "fair marketing" laws exist.

> what we want to prevent, isn't landlords who can target only some group, but landlords who _do_.

Sort of. Landlords will always, intentionally or unintentionally, target one group or the other, simply because they can't advertise literally everywhere. The important things are that the contents of the ads aren't discriminatory against protected classes, and they can in theory be seen by anyone who buys the right paper or sees the handbill or billboard or TV ad. FB's targeting appears to remove the possibility of equality of opportunity to view the ads. There's never a reason to allow filtering by protected classes on housing ads, so FB shouldn't have ever provided it as a feature whether directly or indirectly.
That's not a good idea. You would have turbulent airflow with dust, most energy would get lost, resulting in low efficiency. Weights on cables pulled by electric motors is as efficient as it gets. Not to mention dust bucking up the gears and sockets.
