Hey James.

The issue you're having is that you're trying to test over 7 dimensions, with the majority of those dimensions being irrelevant to an individual taking the test to signal mastery of 2-3 of them.

The standard method in testing to deal with issues of this nature is to provide people with the opportunity to test themselves on modules, rather than taking the omnibus test so that they can spend the majority of it signalling that they aren't good at things they don't care about. If they're good at everything, they can sit for all of the modules. If they aren't, they aren't wasting their time.

Additionally, this frees candidate time up to let you test people in more depth in the areas they're actually professing skill in. From that point, you're open to do interesting things; evaluate question difficulty/time to completion and adjust the questions provided as the test unfolds to match the expected skill of the applicant for instance.

As it is now, you're getting buy-in from corps that little have no skin in the game, but I don't see how the sample test you have provides more signalling value than an applicant having a CS degree or a list of github projects they can discuss.

CentOS is an option, but the hardware will perform better under Fedora due to a newer kernel build to support newer hardware. Feature wise, the only difference you really need to know is that Fedora ditched Yum and switched to DNF. Same command structure, and you can still install yum.

fun fact. Fedora is what RedHat uses to test and flesh out all the fancy features coming in CentOS 8 & RHEL 8. I think Fedora 25 or 26 is what those OSs are being build from.
Is it inherently wrong to publish an ad in the Wall Street Journal and not then publish the same ad in Teen Vogue?
It doesn't expose me to relevant ads. I live in Montreal. My last three twitter ads were for a drug (reported as illegal) something about a new york lawsuit against an oil company? And for a pizza place which doesn't exist in my country.

User targeted ads do not produce better ads, despite everyone selling ads saying so.

I can’t subscribe to that. It’s ok, but it still requires permanent hand holding. Stuff randomly breaks with updates, for example since the last update I can’t scan any more. I also can’t print any more on my networked printer that’s connected to my mac server.

You just made me recall one of my favourite movies:

I think we should ask who has the right to manipulate other people's beliefs into non-sense. Then once somebody believes it does it give the believer special rights?

If traditional religions have the right to do so why don't I, or my group of friends?

But on the whole I would say that Pastafarianism is more of a question than an answer? Well it is an answer in that it tells us we can believe whatever we want and the society seems to have accepted that notion
Yes, but in the past 2-3 years, Assange and WikiLeaks have been doing far, far more than that. For one, just look at their Twitter and leaked Twitter DMs: https://twitter.com/wikileaks

Also, releasing authentic documents, even if they were the sole thing they ever did, can be itself a form of bullshit, even if the documents are 100% real and not doctored, edited, or manipulated in any way. "Bullshit" is distinct from "lying" or "faked evidence". Selectively releasing documents that only push a certain narrative, while not releasing documents and/or intentionally not attempting to acquire documents associated with other narratives, is a form of manipulation, not a form of journalism.

I don't know to what extent Assange practiced these kind of intelligence tradecraft games before the 2016 election, but during and after it, WikiLeaks effectively transformed itself into a private intelligence agency, presumably with Julian Assange at the helm.

Maybe it was because of Assange's personal vendetta against Hillary Clinton (his vendetta being pretty justifiable, considering Clinton's frequent attempts to have him extradited, arrested, and imprisoned, and her alleged but unproven references to having him assassinated as cited by what has been claimed to be anonymous State Department sources; this still doesn't excuse Assange's loss of impartiality, though). Maybe it was because Assange saw this as a way of making the US geopolitically weaker and shuffling the superpower deck a bit, due to his issues with the US government. Maybe it was because he wanted to see the world burn. Maybe he was being blackmailed, threatened, or otherwise coerced by non-US countries' governments. Maybe he became a witting agent of a non-US government (though I kind of doubt that). Maybe a mixture. But either way, he lost all pretenses of neutrality and credibility after his actions during the 2016 election were revealed.

I don't take issue with WikiLeaks releasing the DNC and Clinton campaign emails - they should've released them - but I do take issue with their underlying campaign, strategy, goals, and motives, as made very evident by their PR efforts, public statements, and leaked private conversations.

Organizations like WikiLeaks are a good thing in concept, and WikiLeaks' original stated goals and disclosures do seem to have generally been good and moral, but either something changed, or Assange was playing a long con from the start.
At this small scale it could probably be implemented in an afternoon. No need to pull in an external dependency for something so easy.
I can't ever go back to CentOS/RHEL or Debian/Ubuntu for my personal machine after having seen the flexibility that Arch provides.

Don't get me wrong, technically you can make Ubuntu just as flexible but you have to try to configure it that way. All the conveniences they brought into these distros for simple package management actually sets you up for failure when you are doing larger upgrades. Not to mention that the packages in their repos are often out of date.

I never had my Arch box fail me across upgrades, allowing me to actually be current in the code I run.

It's a healthy middle between Gentoo and CentOS if you don't want to build it all from source but yet still be current.

Even opkg and some IPAs are better than the package manager experience I had with apt-get or yum/dnf.
I could rant about this for hours. I actually just went to a defense for a deep learning paper that had a ton of abstract algebra. I am honestly not really a fan of deep learning and algebra because all the papers to me like- seem to stop at describing some really basic feedforward network as some really specific mathematical structure but these theories a) provide very little explanation of empirical phenomena b) provide no new directions of research in terms of like useful network architectures.

I haven't really come across algebra in machine learning other than people applying it to deep learning.

i.e. https://arxiv.org/pdf/1802.03690.pdf

ie. https://icml.cc/Conferences/2018/Schedule?showEvent=2048

I don't personally find papers like this valuable but idk I have never really enjoyed abstract algebra.

I'm not actually sure that's true. Upon a cursory check, People Magazine has a slightly greater circulation than NYT. Heck, a non-trivial number people on YouTube have greater circulation than NYT or mainstream TV News channels and shows, while filming their stuff in the living room of their apartment.

Oh I didn’t know that. Will look into that!
So build more housing.
That's the way to do it.
My advice as well – I'm running Arch Linux on a ThinkPad. Debian (unstable) or a recent Ubuntu version might work pretty well too. CentOS follows RedHat Enterprise Linux and has way too old software for modern desktop use (unless they have a branch hidden somewhere I'm not aware of).

Running old Linux versions on new laptops is going to be a frustrating experience; ideally all the device drivers you need are mainlined into the kernel of your distribution so you won't have to mess with those yourself.

Thanks for the deeper back-and-forth. I did mean "standing" as brought out here. I.e. simply that failure to focus on profit can create a situation where investors can file a suit that won't just be thrown out.

I'm saying that there's enough legal premise around the idea that the business is working for profit. The investors buy stock with the premise that the business is aiming to provide a return. If they don't aim for that, they can be accused of not running the business in good faith or of misleading the investors…

I'm not saying there's an absolute legal imperative to maximize profit. I'm saying that investors are given enough legal tools in our bureaucratic world that they really can use the legal system along with other tools to bully companies into focusing on proift above other values.

A company just saying in court, "X would bring more profit, but that wouldn't be as good for the world" isn't going to get a suit dismissed if the suit is based on a bunch of complex legal allegations about the company misleading investors or I don't know what other wide range of possible legal arguments are available…

But for Benefit Corp or similar, investors would have less have legal standing to bring suits based on the companies following the social priorities laid out in their Benefit Corp bylaws etc.
Not related but the first thing I thought of was flywheel regenerative braking in cars, except that is storage in kinetic energy not potential energy

Am I supposed to accept your anecdote as evidence? I mean, on the one hand, we have the massive and continued success of platforms that tailor ads to target audiences, and on the other, we have freeone3000's complaint about a pizza ad not being relevant.

Ad targeting works. That's a fact. You can argue that we should kill ad targeting anyway, that's fine. You can make that case, and I'd disagree. But to flatly deny that ad targeting works? That's adopting a private set of alternative facts, and if you do that, we can't have a conversation.
Why do people always go on to the abstract cases when we are discussing a specific example?

> Where exactly does it stop?

It stops in cases when it's not protected and not breaking the law. Housing and job adverts cannot be explicitly descriminatory. It's a clear existing law. There is a clear line. You have to do your best and take precautions to avoid descrimination. When a platform doesn't do that then there's a problem.

Honestly, to a first order, no regular people care about Twitter either. Only journalists, celebrities and a small cadre of tech folks who haven't quit yet still use Twitter. Twitter has only a tiny fraction of the users of Facebook or YouTube.

How much time did/do you spend reading and fiddling? If I knew setting up a machine (incl. picking hardware parts) is no hassle, I would build myself a desktop. For now I’m holding out for a new Mac mini.
In the example, the building owner/manager isn't randomly choosing a publication to put their ad in. They are acting to discriminate against people that don't (or are merely highly unlikely to) read the magazine.
It's rare to outright block an instance (for not moderating child porn or something of course but not otherwise really)

Instead most "blocks" are just muting from the federated timeline, precisely so that you're not cut off from contacts.
I love Mastodon but the only thing stopping me from using it is the way they approach federation [0].

The "ideal" for me is to make an account on a centralized official Mastodon instance (with Keybase verification, if needed) and then be able to seamlessly join another instance without having to sign up for that instance separately to be a member -- and thus not having to make a per-instance account.

That way my account is created once, and I can jump between other instances OAuth-style.

I do like the fact that niche instances exist, but in my opinion it's better to be known as [username@mastodon.social] even when being a member of [@niche.social] much like how Disqus or Gravatar works, in principle. At least the option would be nice.

Rhetorical or not, this question deserves to be upvoted more.

How is it different from hardware store that sell knives that can be used to cut vegetables or people, at the discretion of the buyer?

Maybe a better way to deal with that is a different regulation. Mandate the industry designation in the ad and if it is something protected by existing laws, like housing or job ads, remove filters that allow for adding or removing by protected category from the interface.
This is the part I don’t understand. Why do they go through so much effort to have me binge watch Netflix. It costs them bandwidth, and it makes me go through the quality stuff quicker.

If they instead tried to get me watching just enough to keep the subscription it would be cheaper for them and I would have be more happy with the mean quality of available options
It's the difference between recommending the consumer line and business line, they are not related technically. Lenovo's consumer line is Ideapad, their business line is Thinkpad. If they tried something similar on a business line, they would go bankrupt because they would never get another contract again. It would fall under Industrial Espionage which is illegal. That's why governments and large corporations still buy Thinkpad.
Looks like if this goes to trial it's all going to hinge on exactly what "To publish an advertisement, with respect to the sale or rental of a dwelling, with an intention to make a preference based on race, color, ..." means. To me that seems quite clearly to refer to the ad itself - that the ad cannot make a preference, implicitly or explicitly, for any group. However, who the ad is shown to would seem to be another issue altogether.

If this applies even in who the ads is shown to, think about the implications. What if I run an ad in e.g. "Golf Digest Weekly"? Would that be unlawful for that publication to actually publish? What if I place a billboard in a high income area? Is the billboard renter liable? Is my ad unlawful? If I place a for-sale sign in the yard of a vacant house in a high-end neighborhood, is that unlawful as well?

I'd like to think the HUD has thought out their case and it's implications, but I don't see how you can take their interpretation of this law without practically destroying all housing ads - which is clearly not their intent. So I'm very anxious to see how this plays out in court!
Seems quite useless to me as the earth's gravitational field is not very strong.

Supposing that you could store the concrete blocks at a height of 50m (which is already a lot), you would need roughly 8000 tons to store 1 MWh. Taking account concrete density (2400kg/m^3), that's 19000 barrels !

The FHA is a 50 year old law. Facebook isn't getting in trouble for offering targeted advertising, they're getting in trouble for allowing explicit discrimination on the basis of sex and ethnicity. This has nothing to do with correlations.

It's not significantly more efficient than pumped hydroelectric storage which is 70 to 80% efficient. And whilst it might be able to store quite a lot of energy, it can't release it particularly quickly I'd estimate the 6 crane motors can maybe generate a combined 1MW which is a paltry amount of power compared to even a tiny pumped storage facility.
The problem here is that the journals do not provide proper review. Perhaps it's a presumption of honesty/integeity, but they need to start asking if the experiment was plausible. If it would have been expensive, who funded it, etc...

It's sad that science has come to this.
Well I think taken literally, "not maximizing profit" can't possibly be sufficient grounds for an action. Nobody really has any idea of whether any particular strategy is profit-maximizing, so it's hard to believe a company can be sued for not following a profit-maximizing strategy.

But shareholders can sue over alleged harm to a corporation. I'm not a lawyer, so I really have no idea what the standard is here. But purely speculatively, I suppose someone could be sued for repeatedly missing obvious profit opportunities because the executives objected to them on ethical or other grounds.

I get the impression, though, that shareholders are more likely to sue for committing an active blunder (like selling off a division for an insanely low price) rather than for missing an opportunity.

There's a list of some famous shareholder actions here: https://www.dandodiary.com/2014/12/articles/shareholders-der...

More charitably, I think what people like quadrangle are really meaning to say is that there is a significant legal framework that very strongly incentivizes and is inspired by the idea that the first obligation of a corporation is to maximize profit. And if that was the point, then I think that's pretty close to the truth.

Sure, you won't be arrested for not maximizing profit, but remaining in business without attempting to put profit first is sufficiently hard that it typically requires special legal protections (as in B corporations).
> It stops in cases when it's not protected and not breaking the law.

Since we're discussing the scenarios that the law might cover, your claim seems rather circular.

> It's a clear existing law. There is a clear line.

The entire point of my post is that the line isn't neat and clear at all. Very similar concerns come up in various other contexts, and we as a society are going to have to deal with the internal contradictions of current orthodox thinking one way or another, and probably soon.

Your comment is just asserting that the problem I described doesn't exist. It does. Wishing away reality doesn't make it disappear.

Can't believe you bothered to track down and post this on both my comments lol. Wasn't aware of that part of it. Also just because they can do that doesn't mean they should.

Edit: Not sure why this got flagged. I acknowledged that I was unaware of that provision. Simply stated that I thought it was mildly humorous they commented the same thing on both of my comments.
As a musician (i.e., someone who frequently carries large objects up and down stairs), knowing the count is extremely useful to me. A significant portion of the time, I cannot see the ground. Instead of getting close and then feeling around with my foot one step at a time, I can just count to 14 (or whatever it is) and know I'm on the floor.

Even in a new building, it's common to walk the stairs at least once before hauling heavy equipment (to see where it's going to go), so I almost always have a count before I start.
I agree that’s a reasonable explanation of why it happens, I still find it frustrating.

Aleppo is a great example. Why would I advise someone not to go? Without knowing who they are, when they’re going and for what purpose, it seems preposterous that any advice would be given at all. Asking a few questions would highlight if they’re making an informed decision and if they possess the information I hold. There are reasonable reasons to be going to Syria (soldier, aid worker, contractor, reporter) and repeating the last headline read is not useful.

As for jumping off a cliff, isn’t that cliff diving? If you mean suicide, hopefully you have first hand experience on the value of life, which could be provided as useful advice.

My frustration is how quickly people provide their opinions as advice, often oblivious to how informed the receiver is on the given subject.
Anything that sabotages advertising, especially ad-tech, is a positive thing for the world.
It is, however, Facebook's obligation to abide by the law, particularly 50 year old laws with decades of settled case law.
I wonder if you could compromise and use powdered concrete in a closed system? High powered fans could blow the fine powder upward in a silo so it would act like a liquid. Then large paddlewheels catching the powder could power a generator coming back down. I have no idea if powder going up a tube has less friction than blocks on a cable/pulley, however.
If you're already considering setting up a separate system for this, you probably don't need to send in-app messages. Why not use Slack?
