"The round-trip efficiency of the system, which is the amount of energy recovered for every unit of energy used to lift the blocks, is about 85%—comparable to lithium-ion batteries which offer upto 90%."

That's quite efficient. Maybe they can get creative and build something different every day. One day you get a big pyramid, the next day you get a big elephant. That would be quite entertaining.

> Show me something exciting I can do with it that I can't do with twitter, instagram, or Snapchat.

Moderation and content quality.

You know the reason why people prefer reading the New York Times instead of checkout-counter tabloids? The reason why people like buying from Amazon instead of Ebay? I mean, Ebay usually has better prices. Why would anyone buy from a store just because it's able to (or at least claims to be able to) filter bad products and keep off scammers?

That's Mastadon's advantage. The userbase isn't crap. Twitter, so far, has shown no indication that its userbase is ever going to be anything except crap. I don't think it's possible for Twitter to even start fixing that problem. Moderation doesn't scale.

If you're on social media not just to connect to friends - if you're on social media because you want to actually consume cultural content or interact with new communities, then this is like comparing Youtube and Netflix. 90% of everything on Twitter is garbage, and it's suddenly your responsibility as user to sort through all of it?

People want a platform that just works. They don't want to have to download custom block lists off of Github, or turn off DMs whenever anybody gets mad at them. They don't want to have to curate their own timeline. They want somebody else to do it for them, and Twitter can't do that.

> Alternatively, is there some new and novel porn that Mastodon will allow me to access?

Probably? Twitter has policies about pornography - they're inconsistently applied, but they're there. You could make a dedicated Mastadon instance that allows whatever. You can also choose not to have porn show up when you search across an instance because, again, Twitter can't moderate and Mastadon can.

I would feel a lot more comfortable allowing a kid to sign up for a Mastadon instance than Twitter.
Aside the point a little bit, but I just made a mastadon account today and I've already seen a few dozen female accounts that exist solely to promote their patreon/gofundme accounts. The exact same type of negative atmosphere that plagues snap, IG, and twitter.
The ads themselves are protected, but wouldn’t the publication venue not be covered? Otherwise housing ads in the Chicago Defender would be illegal right?
Yeah I guess there is a balance you have strike in order not to become an Orwellian society.
Sorry to hear it was that bad! :( I'd love to hear your experience, especially if I was directly involved -- you can reply or email me anonymously at james@cspa.io. If you know anything about Crunchyroll's early culture, I always made a point to listen to feedback and improve ourselves. It'll be the same at CSPA.

Crunchyroll's interview process definitely was not consistent, which is why I spent my final two years there trying to improve our processes. I learned a lot from it, and that's why we're doing CSPA :)

Now why couldn’t we build something like this right into a wind turbine? They’re already pretty high up. Just have it lift one giant concrete block up and down.
These are the specific points they are going after:

-display housing ads either only to men or women;
-not show ads to Facebook users interested in an "assistance dog," "mobility scooter," "accessibility" or "deaf culture";
-not show ads to users whom Facebook categorizes as interested in "child care" or "parenting," or show ads only to users with children above a specified age;
-to display/not display ads to users whom Facebook categorizes as interested in a particular place of worship, religion or tenet, such as the "Christian Church," "Sikhism," "Hinduism," or the "Bible."
-not show ads to users whom Facebook categorizes as interested in "Latin America," "Canada," "Southeast Asia," "China," "Honduras," or "Somalia."
-draw a red line around zip codes and then not display ads to Facebook users who live in specific zip codes.

Try starting a new profile under your account and then selectively thumbs-up shows. It was surprisingly effective for me. Also made sure to clean up the watch history on the Netflix website when it got polluted with someone else's stuff or shows that I regretted watching.

My experience is that watch history affects the recommendation engine more than thumbs up or down.

Netflix funnels people towards their own properties in the hope of raising the value of their new IP and network. Some are hits. Some are misses.

People watching Bright doesn't mean people, on the whole, liked Bright. Making a Bright 2 might just mean that making another was the easiest and cheapest way they had to honour Will Smith's contract, which may have primarily been inked to keep Will Smith out of putting together exclusive content for other streaming services he was in talks with.

The idea that the quality of the content itself is the end-all of the business decision to fund a series or movie is misguided.

Regardless, this misses the point. Consumers are right to push back against lowered content standards, and opaque business choices don't trump that. If Bright was actually good, it would have been fans that were clamouring for Bright 2. They weren't. The fact that good money is following bad doesn't mean the series is suddenly a success.
Linux these days is incredibly stable. As long as you have a laptop that has reasonably high quality (read: open) drivers. Intel graphics, Wi-Fi and a decent SSD/HDD from a known brand is usually enough to have a trouble free personal compute platform.

I have a precision 5520 and haven’t had a single Linux/hardware related issue, before that I had a Thinkpad x201s, and an x201 before that- and further back still I had a T400.

It’s been more than a decade since I’ve personally seen a Linux+hardware issue.

I'm not really seeing how it's Facebook's job to enforce this particular law as opposed to the HUD whose job it is to go after landlords/sellers doing the actual discriminating.

Just because the advertiser can use these tools to discriminate doesn't mean they actually do or mean they aren't 100% personally responsible to comply with the law.

I was kind of under the impression there were checks and balances to prevent these sorts of governmental fishing expeditions...
Recent Adam Sandler movies are a great example - he makes huge money off of small budgets and people watch them.

Is it any surprise that they who deplatformed Alex Jones allow landlords to discriminate as well?
JCL, 360/370 ASM, COBOL.

They were still teaching this shit at my school in the 90s. Encouraged you to take COBOL II because "there's so much old code around you'll always have a job" (left out the part about a job you'd rather kill yourself at).

Peter Gibbons was updating code for the Year 2000 switch over.
It's not that easy, because there are many proxies that correlate with protected categories. For instance, take a look at the greater DC area with census data on race. You can easily target regions without explicitly using race.

Not sure what's unclear. Some people are pro-immigration, and some are anti-immigration, and some don't give a fuck, and some are undecided. The London wait staff you encountered, and the 65+ million people you didn't encounter, the overwhelming majority of whom are not wait staff, and most of whom live outside London, are all somewhere on that spectrum of opinion. The words you selected, obviously, I think, refer to those who are anti-immigration. If you're willing, you probably don't need to be forced, right? So, unlikely I was referring to the pro-immigration people. The first words of that paragraph are "The pro-immigration groups' big mistake", which hints at the pro-immigration stance not working out too well, so clearly there's push back from people who are anti-immigration, and those are the people who have been forced to accept immigration they didn't want.

> Let's spin some numbers to further illustrate the poor energy density of gravity-based storage systems. Assume that you have a 100 kilogram lead weight that you can lower into a 10 meter deep hole in your yard.

> Now, how much energy can it store? This is given by potential energy formula E=mgh, thus E=100kg⋅9.8m/s2⋅10m=9.8kJ≈2.7Wh.

> For comparison, a single AA-sized battery stores about 2Wh of energy.

https://physics.stackexchange.com/questions/305563/why-dont-...

Wind turbine height: 99 meters. 100 kilogram lead weight == about a large person. So, a normal turbine maybe can hold about 100 people's worth of additional weight (elephant or two) * 10 (height multiplier) = ~1,000 AA batteries worth of stored power.

> If the tables were turned here and the Cubans or Russians were accusing us of a sonic attack we’d be screaming that it’s a disinformation campaign

I do not follow Cuban politics (and not much Russian), but Russia nowadays are always accusing USA of some evil -- watch the official 1st channel or read gov't radio transcript: planning an overthrow of their government (via supporting this or that NGO), destabilizing an economy, financing a war and killing Russian citizens (Ukraine, Syria), etc. etc.

Much of this is for internal consumption, and generally the reaction in the US from those who can read it and care to is "meh, business as usual". Trying to influence minds, for sure; but this is par for the course for politics.

Great feedback -- thanks!

We're constantly improving the CSPA questions, and our latest iteration has quite a few changes. Some of the examples you mentioned assess how detail-oriented the candidates are. We're interested in how this data correlates with how bug-prone someone is.

That said, we trimmed some of those down in our latest version and replaced it with more substantial questions.

According to the Norwegian pilots currently flying the F35, it defeats all other planes it has gone up against due to its tech and stealth superiority. Only the F22 - which was recently in Norway for exercises - provided it a good challenge.

The Israelis are actively using the F35 in missions. Their air force is not known for spending large sums of money on planes that don't work.

Nobody else has fielded a 5th gen plane in meaningful numbers, including Russia and China. There's a reason for that.
I am considering going into a CS PhD focusing in ML. The mid 40k-70k range was from quick google search I did for CS post docs in ML in lower cost of living areas where the cost of living is much lower than on the West Coast. I am trying to look at career prospects and weigh whether it makes sense to stay in academia or jump to industry (after I complete a PhD). If wages are closer to 60k-100k for post docs, then I may consider staying in academia for some time after completing a PhD depending on whether my career interest shift.

Well, it’s well-known [citation needed] that to be taken seriously, any vague business idea proposal must exhibit Proof of Buzzword. Just like in the Bitcoin protocol, when a Buzzword has successfully been mined enough times its reward value halves and one must add new, previously unexploited buzzwords to the proposal to maintain its credibility.

By this token web2.0, ACID, Cloud et al. have almost no buzzword value left. Even Bitcoin is very 2017. Which is why the only logical solution is nano-engineered quantum genetic algorithms with dark matter entanglement in P-space.

Also, a nerd’s way to walk on the plane is to ignore sidewalk or other markings and cut a straight of a line to the destination as possible.

"Thats why some companies stop hiring ppl after 30s because they are simply not able (statistically) to keep with all of it. "

From my experience the young guys aren't keeping up either. They have a very short period where the framework they have learned is the one that's en vogue. 3 years later they are also "behind" because if you do actual long term work you are behind almost by definition. You can't abandon your previous work and rewrite everything every two years because your tech isn't cool anymore.

"How do they determine what's a housing ad?"

You ask the user to say what type of ad it is, under penalty of violation of contract, and contractually obligate them to carry the legal risk if they lie.

There's no requirement that it be done via some fancy ML algorithm. I would expect that unless FB actively attempts to piss off the government, that would pass legal muster. Goodness knows I've signed enough agreements where I've agreed to very similar clauses just in normal day-to-day life.

> Or are you trying to argue that nationalism is necessary for a country to transition into a democracy?

I'd argue that nationalism is a requisite step for a diverse country, including multiple ethnic or cultural groups within its borders, to become a democracy. (And I'm sure I'm cribbing an old idea in the field here)

It seems like there's little basis for common action without a supergroup which includes, binds, and restrains all otherwise oppositional parties inside a legal framework.

I'd argue that's why uni-party "democracies" tend to be so fragile. When the party becomes the state, then opponents of the party can only be opponents of the state.

There are systems like that:

* old empty mine in Germany. They pump air into the mine and then heat it to get extra energy when letting it out.

* big underwater bags next to wind turbines. Wind turbine directly pumps air into nearby bags. When there is no wind, the air is used to rotate the same electric generator that the wind turbine uses.
I like the idea, but I am wondering how big these will need to be. If one of their prototype towers can store 20 MwH, at each one requires a circle 300 feet in diameter, than it will require a lot of land to do this.

I wonder how this compares to lithium on a power store per square foot metric.
0) Not to justify but to give a similar example: CL rarely takes (or took in the past) down zillions of postings that are/were blatantly illegal, i.e., “Seeking roommate: female ONLY.”

1) People are going to discriminate, even if it’s illegal. Heck, I was at a restaurant and an Israeli couple were smugly grinning about how they were discriminating against a candidate whom was “male and too old” by wasting his time and not calling them back. It sucks, but you can’t legislate not being an asshat, even with ostensibly anti-asshat laws.

I don't think the humanities departments are particularly successful - but they've been underfunded and horribly hamstrung by political and administrative interference for about half a century now.

It's also not that Shakespeare's going to make anybody a better thinker. It's more that stuff like this sets the tone for the culture in general. If you don't really teach hard, interesting culture, then all the people who might have been interested just get the feeling that culture is kinda garbage and go on to engage with hard interesting ideas in other fields. Which leads to a public culture that's not in any way healthy - one that's really just people passing the time, that doesn't really push us or make us grow.

History shows this kind of thing is just incredibly dangerous. If everybody likes culture that's enjoyable and easy, easy, self-satisfied thinking predominates. Then suddenly everybody is marching waving big flags and wearing funny hats, because it's a lot of fun, and makes you feel great to be part of something.
