There is no free lunch. Any forced adjustments we make to reduce false positives, will increase the false negatives. It's up to us to decide what trade-off we want and the algorithms will simply adapt to that.

If we believe certain attributes to be irrelevant to a situation, we need to build systems that are completely blind to these attributes. This is how double-blind trials, or scientific peer review works.

I have an issue with Facebook doing this to OTHER PEOPLE and thus dramatically influencing the world I live in. I can and do block their Javascript, but that doesn't block it for others.

The idea that our decisions are just independent and everyone can decide for themselves is (A) wrong in terms of how we are affected by decisions made by others (B) anti-social and (C) denies the reality of organized power.

If Facebook had to just be a bunch of unorganized, separate, independent people instead of a company with organized structure, they'd not have the power they have. They have power because of their organized structure. The idea that the other side of thing (the regular citizens) should only act as isolated individuals while the companies act as enormous organized power is ridiculous.

They have also asked APKMirror to stop hosting Telegram APK's (ie. The install packages for android devices).

No word on whether or not the F-Droid repositories have been contacted as well.

With PGP (for that matter, PKE generally), you always need the original recipient to stay alive and use her private key to decrypt.

With proxy re-encryption, you don't. So any use cases that involve Alice disappearing while others continue to be able to encrypt for Bob (even without knowing who Bob is or what his public key is) are good ones for NuCypher.
Public Speaking Anxiety-It’s All Inthe Mind
I think I disagree, but in a good way. Apple needs to protect privacy. Google, FB, et all are pushing devices that upload as much information about users as possible. The most recent Apple update resounded with me in that it said 'privacy is a fundamental right'. What Apple needs to tackle is the issue of becoming an advertisement agency.

Sorry, but this is actually a real world situation that happened - I have a Jewish ancestor who was named Adolf before WWII but after Hitler's rise unsurprisingly chose to go by his middle name instead.

You can ascribe it to "Godwin's law" as much as you like, I just find it a more realistic example than some hypothetically disadvantaged "Bob".
Maybe on US.

Around here ChromeOS is a kind of rare animal hardly seen on any consumer shop, and when it appears it is usually tied to some promotion to get rid of those in stock.

OS X is everywhere on northen Europe big cities, but go south or to the country side where many people dream to go over the 500€ barrier and it too becomes a rare animal.
As blockers can be very bad for performance because they are dumb. uBlock Origin is good though.
You do realize that GNU/Linux also runs computers that aren't anchored to a desk, right?

GNOME has been working on improving touch interface support with an eye towards mobile devices for years now.

Personally I tend to look up where I'm going prior to leaving rather than relying on turn-by-turn navigation systems. I load up a map, and use navigation features to route my trip, and I personally consider this navigation - just not realtime. Usually I write down the directions on a scrap of paper. Not everyone willfully carries around a surveillance device, and options like GNOME maps makes it possible to still have modern technology at your disposal without participating in these highly invasive ad-funded surveillance systems.
It should be noted that "beer" in this context refers to 12oz of 5% ABV beer, not 7.5% IPAs (or worse).
The reasons the Hyperloop doesn't work well would require a separate forum to list. It seems a bit biased to simply say "because of Earth's atmosphere".
Homicide rates are unlikely to have this kind of bias though. And they're heavily against blacks. It's unlikely whites being murdered go unreported, or that anyone gets off with a warning. But inner city homicide has a low solving rate. If the reporting rate is also lower, then it could be even worse than the 4-7x overrepresentation of blacks in homicide.

This seems to be the case in London, too, so it's a bigger issue than just the US.

But for things like drug possession, yes, blacks probably get stopped much more and not let off with warnings much less.
I put Apple and Google on the same position as well.
Infuriating, I'm a huge fan of these services. I initially thought they would just be toys, but they've removed any uber/lyft around the city for me - they're both faster and cheaper, they park just like bicycles, they don't cause any noise pollution, and they completely eliminate last-mile carbon output.

Sometimes SF is an infuriating place.
What do these custom apps do and why aren't they webapps?
Agreed. If you understand the resource requirements of your environment then vertical scaling is totally viable. Ive seen lots of scenarios where teams shoot themselves in the foot because they fail to just think critically for a second about their deployments.

Consider a Redis-based cache: For future proofing you could introduce a sharding scheme that deterministically allocates keys based on cluster size. That would be operationally pretty complex. Not to mention also introduce complexity in edge case scenarios (e.g. your cluster size is transitioning).

Alternatively, you could do a little back of the napkin math to figure out what the size of your keyspace is going to realistically be and just...allocate a machine that fits your needs up front.

Obviously we could make arguments about budget and all that, but those are optimizations that are better to defer.
This is an interesting case because they’re phonemically the same (long-I, L, schwa, V) but may be realised differently phonetically depending on your accent†. I bring this up because I’ve always wanted to be able to tell speech recognition systems specific features of my accent, say through a series of questions (“Do you pronounce ‘cot’ and ‘caught’ the same or differently?”, &c.) in addition to ML training, because as it is, they persistently mix up certain words—“I’ll” and “all”, for instance.

† With “isle of”, I have two syllables and a velarised (“dark”) L in “isle”, a mid-central vowel (/ə/) in “of”; with “I love”, I have one syllable in “I”, a non-velarised (“light”) L and an open-mid back unrounded vowel (/ʌ/) in “love”.
> My point is that institutions making such decision should not be able to make decisions according to these 100,000 unexplained factors.

But how does that help anything? The objective factors have the same potential for bias as the seemingly irrelevant ones. All you get by excluding factors is to increase bias by not considering information that could mitigate the bias in the factors you are considering.

Suppose that 80% of black men would be rejected for a loan based on your preferred set of objective factors. Of that 80%, many would actually repay the loan, but none of the objective factors can distinguish them from those who wouldn't, and when averaged together the outcome is to refuse the loan. If you used some seemingly arbitrary factors that happen to correlate for unknown reasons, you could profitably make loans to 60% of them instead of 20%.

How is it helping anyone to not do that?

Isn't one of the long held up tenants of software development that you should "pick the right tool for the job"?

Because if, as a user the choice is between another shitty JS/web-app masquerading as a real app, and an app that's built properly with native API's and native code, I'm 100% going to choose the latter.
The Reluctant Gatekeeper
I would love to help out if possible. I'm a Canadian citizen but not in Halifax, so I guess I can write my MP but I don't think they have much authority to look into a provincial matter like this.
To me the fundamental difference between a PC and a tablet is the software ecosystem: can you install any program/OS or must you install only those approved by the platform owner; can programs access system resources liberally (including a shared storage namespace) or are they tightly sandboxed; how much of the underlying infrastructure is visible to and manipulable by the end user. Compared to this difference the question of whether the device has an integrated keyboard or not seems minor to me.

Moving from a PC like ecosystem to a tablet like one is a net loss in my opinion. People are willing to absorb this loss and enter into a walled garden because right now building iPad-like hardware is not easy. I hope it doesn't continue to be so in the future.

But what if someone had just moved to Canada from Norway and didn't realize that tax return information was supposed to be private? I think it's fair to put most of the responsibility on those who have implemented a system that serves private data in response to public http requests. Presumably this is the party that has both been entrusted with the private data and has the technological and legal resources to understand what can and cannot be served publicly and appropriately configure their systems to do so.
Those are good questions to ask (particularly what the best construction technique is for vertical shafts), but I think your numbers for the elevators are wildly wrong.
Firstly, there should be no real reason for the tunnels to be deeper than about 30-50 feet because sewers and utilities are all concentrated at backhoe depth, which is shallower even than that and building foundations are pretty easy to avoid. The biggest driving factor in depth is probably disruption to the surface during tunelling, which requires staying ~2 tunnel diameters underground. That cuts your elevator time estimates by 2-3x.
Secondly, 1ft/s is really slow, both by the standards of other elevators in the world and in comparison to their own demonstrated prototypes. The car elevator they demonstrated in July 2017 appears to move around 3-5ft/s once it gets up to speed [0], and I expect that number to only increase, particularly if the shaft gets deeper. Human elevators reach speeds up to 50ft/s in tall buildings, and while there's no need anytime soon for the Boring Company to hit those kinds of insane speeds, there don't seem to be fundamental reasons they couldn't if they needed to.

[0]: https://youtu.be/9jvD_dFA44g

Combined, those factors imply your numbers are close to an order of magnitude off, and imply a reasonable number of elevators in the 30ish range. There are real challenges they need to solve, but I don't think elevator times or count are one of them.

Stopping a production line during a ramp up for days is a normal part of the business.
When the line is already running, it is not the best of all news, because something malfunctioned -- like a big press putting errors into some bigger parts -- and needs to be reworked. Sometimes, however, they are reworking the line. So these stops are planned and there usually also exists a very detailed plan how to approach this. This is usually a high-stress situation due to a standing production line causing a loss to the company, and a separate specifically for this trained team is doing the rework with the workers being concerned with the parts of the production line being the 'consultants' to this other team. Resp., helping operationally. During the setup of the production line for a new model it is standing for weeks. Hence, no one is having unpaid enforced vacation whatsoever. At least in Germany.

Smells like clickbait here.
Huh? You've somehow interpreted that to mean that no business would serve a poor person ever? That doesn't make any sense, and isn't what I said.

Let's try again: If there is a business that is at capacity, is it appropriate for it to use racial criteria that may have some ability to predict how much a person will spend, if this increases profitability? Is not doing this "erasing inconvenient facts"?

Generally I agree with you but for Electron we're talking about own-goals the developers inflict on themselves. No one outside of the HNosphere uses Electron apps.
And the Noord-Zuid Lijn almost bankrupted the city after all the historic houses at the end of Vijzelstraat started collapsing and people had to be evacuated in minutes for multi year hotel stays! The cut-and-cover stuff they did when they built the original metro was much more destructive to places like Waterlooplein, but also much lower risk...
Worth pointing out that not all electric scooter companies chose to disregard city regulations. Waybots has made the choice to work with cities to get approval before launching. Seems like a better approach, and one likely to give them a big advantage long-term. I believe they're still the only legally operating electric scooter sharing company in the US (currently live in DC where they got permission to launch).

On the other hand, I think this is great.

These dockless systems are simply a way to move the negative externalities of the system onto the taxpayer. They clutter sidewalks, result in poor rider behavior, and generate massive amounts of e-waste.

Sometimes, SF actually makes the right call.
Transit to airports is generally a secondary concern. The only regular group of riders that would use such a line would be airport workers, because by definition there are not that many travelers, and on top of that many of them with luggage or in large groups could find it easier or cheaper to pay for the door to door ride of a taxi.

The O/D pairs of people going to and from airports also tends to be very dispersed, which is not great for rail unless you have an extremely comprehensive, rapid rail network covering nearly all possible trips.

Airports also, by their nature, tend to be out of the way and away from busy neighborhoods, which limits their potential catchment. Even when they are linearly arranged, terminals are generally set back from these linear routes due to their circular road networks and parking requirements. Look at how much additional mileage is required to serve the terminal at Dulles in DC, for example: https://i1.wp.com/www.thetransportpolitic.com/wp-content/upl...

Finally, airport layouts themselves tend to be really bad for transit; common configurations for airports, laid out in a circle (JFK) or a very long terminal (LGA) will require some significant chunk of passengers to walk to and from any rail station sufficiently long enough for a regular train, to the point where you need a people mover around the airport anyways (SFO, ORD). And if you need a smaller people mover to shuttle people around anyways, why not just shuttle them to a central train station a bit of a distance away, so that the rail can effectively serve both further destinations and the airport passengers?
If Linux users don't have any issues putting their documents on Google's servers, they can do the same with Office 365.
I'd be pretty amazed if it was even possible to construct a model that would answer that question.

In the article's example, you're constructing a model to determine how a movie might be reviewed. The data indicates that movie reviewers may be reviewing movies with male leads more positively than movies with female leads. There are a lot of possible reasons for this other than "men are better than women", so why would you simply reject the result out of hand?
> Developers still request too much
..
> it's gotten a bit better
..
> It's a very small improvement, but it helps
..
> These are all small steps

Thereby illustrating the parent's point that developers will still ask for too much and that the power balance is in favour of the developer.

Apple on the other hand heavily restricts what developers can do. It's developer-hostile, but user-friendly.

Western media intends to portrait "china" as one single top-down entity, but as a matter of fact it's not.

There are thousands of bureaucratic federal or local government branches can start an Internet crackdown.

The whole "anti-gay" nonscence might came from a office clerk smashing his head for April KPI campaigns and baidu'd for random shit to block and passed through the chain of command. That's it.
In San Jose, people are completely irresponsible with these scooters. Since they can park them anywhere, they show up in front of stairs, in the middle of sidewalks, in front of doors, and other locations where they impede pedestrian traffic. SF might have gone too far, but it was pretty clear, at least to me that some regulation was necessary.
Think of it like so: you have a robot that anybody can ask anything and that will answer any and all questions truthfully. Whose fault is it if you deliberately tell the robot non-public information?
This has nothing to do with the topic at all but I really enjoyed your comment. I learned something today. Thanks!
Agreed. Have learned to love the very short travel keyboard of my Touch Bar MacBook Pro. I note that my typing is more effortless now somehow.
I've seen these pop up all over the bay and in LA recently. More often than not they end up immediately abandoned all over public spaces as soon as they run out of batteries or the first free ride is over. Bird particularly seems the worst. The scooters are really under powered and have tiny batteries with seemingly nobody maintaining or charging them, so they just end up laying around. You also get completely inexperienced riders with zero safety equipment driving around in the streets causing issues. It's just another example of a short sighted attempt to arbitrage the public well being for private profit.
I am by no means siding with Amazon - check my post history. But as far as I know, there exist state and federal laws covering this. Even in my podunk state, law requires an uninterrupted 15 minute break per 4 hours worked, and even guides when that time must be allocated. Anything over 6 hours must be given an unpaid 30 minute meal period. Not perfect, but we aren't pissing in bottles.

You're being downvoted - maybe because of your tone - but I partially share your sentiment. A good counterexample to
"overdistribution", not without its own set of problems, is the LMAX architecture.

See: https://martinfowler.com/articles/lmax.html
I think you’re going to see cities acting much more quickly to clamp down on services like this. They have realized that Uber and Airbnb got the proverbial elephant’s nose under the tent, by the time they got around to trying to regulate them it was too late.

FWIW, I think dockless bike/scooter share is a great idea, but having seen what a mess it has become in China, there do need to be some ground rules so that pedestrians aren’t having to step over piles of them to walk down the street.
All comes down to uptime.

One box can’t be distributed across multiple racks in the data center to guard against downtime if a switch crashes. Never mind that—one box can’t be deployed across multiple data centers. If you deploy to multiple DCs you can fail over if one DC starts having issues.

Then there’s deploys. Do you canary your deploys? Deploy the next release to a subset of production nodes, watch for regressions and let it ramp up from there? Okay, I’ll give you that one, it could be done on one big box.

In any case, payments aren’t CPU intensive but it’s a prime case of hurry-up-and-wait. Lots of network IO, so while you won’t saturate the CPU with millions of transactions on the same box, I could easily imagine saturating a NIC. Deploying to shared infrastructure? Better hope none of your neighbors need that bandwidth too.

One transaction likely involves checking account and payment method status, writing audit logs, checking in with anti-fraud systems and a number of other business requirements.

(I lead a payments team, not at Uber but another major tech company)
BART SFO is technically direct to terminal but only because you change to a specific spur line. This is similar to the JFK air train and seems designed to support the taxi union. Each such change cuts the number of poss Le riders dramatically, especially when lugging bags.
Kind of funny that they finally found something to hook the rest of 'em - all the strait-laced people as you say. Many people would never be caught by any of the typical addictions -- Smoking is socially stigmatized, drugs are illegal, alcohol addiction is kinda sorta alittlebit mostly "hereditary" in the loosest sense of the word, gambling for most people requires a long car trip. But a smartphone has none of those limitations.

EDIT: I suppose the most widespread addiction is coffee. Still king.
