Yeah then you get into situations where they're going all out trying to get you to tip. Offering stuff, not shutting up, etc.

I used to prefer Lyft due to the silly SV smugness of Uber, but outside the US I depend on Uber and have come to prefer it.
Today I visited the site again and now it started to show me the same download ads.

So it is still relevant. But how these ads are able to pass through AdWords review.
Good on them for doing this, I know women who have used shelters and I don't really care why Amazon are doing this, it's probably a good thing. Maybe Amazon can also finally build a men's shelter that doesn't die because of threats and intimidation.

Just kidding, if they did that, it'd defeat the probable purpose: to draw attention away from the (legitimate or not) public criticism of their employment standards.

Go ahead and downvote, today's karma earnings are burning a hole in my pocket.
Yeah? Taxis no longer exist?
Interestingly, Apple does its business the very same way for their app store. For all paid apps and in-app purchases, Apple will collect a flat 30% fee.
Which makes me think there might be utility in always running Windows (or other OSes) in a VM. If the malware assumes VMs are bad and self exit in response, then it should be safer to run everthing in a VM. A side benefit would be you can perform snapshot backups and easily migrate your main environment to new hardware.
Maybe they will build a permanent factory for an army of robot lawyers to protect them from legitimate monopoly claims.
If you specifically use the access, by, say, clicking "god mode", I think the CFAA views that as unauthorized. And it really is unauthorized. It's like the office not changing the keycode so you go in from time to time to read reports.
AT&T was responsible for much of the base technology that made packet switching even possible. They did however stuck (largely for good technological reasons) with circuit switching all the way thru, even if it was largely digital by 1984.
I'm not a mathematician, but it's my understanding from what I've read that part of it is becoming used to groping around in the dark, sometimes getting stuck, and accepting that as normal. Solving the really tough puzzles means getting stuck a lot.

This might explain the relative lack of attention towards the user experience of non-mathematicians?
Sorry I misread it as the NSA was developing the holes as in backdoors, intentionally creating the vulnerability.
If you are in London and you have got to get that famous child prodigy to the film studio with chaperone and teacher then you will be ordering them an Addison Lee private hire vehicle or better. A regular cab or some unlicenced 'Uber' gig-economy 'cab' isn't going to cut it.

I expect that other parts of the world are the same.
The aestivation hypothesis for resolving Fermi’s paradox [pdf]
OTOH it means that laptops won't activate until they are on a work network, for an SMB worm that's probably not a bad strategy.
It's more complex than politicians looting for personal enrichment, and it feels like those corruption cases are handled with an occasional FBI arrest here and there.

Ever notice how some of the political candidates are supported by some public employee unions, e.g. a candidate supported (and frequently financed) by police, teachers, prison guards, etc.?

Well, that same politician, once elected, is frequently in charge of negotiating the public sector compensation and pension benefits. In what might come as a total surprise, they turn out to have very weak negotiating skills when it comes to dealing with unions that invested in their previous rounds.

You don't have to look very far - as far as few years ago the city of San Jose had to suspend hiring policemen, and lay off some junior teachers due to funding issues. Meanwhile on the other end of the paycheck spectrum a bunch of public employees were throwing early retirement parties, having locked in a six-figure pension for the rest of their lives http://www.mercurynews.com/2012/08/30/bay-areas-200k-club-an...
Careful, most old scanners out there only talk SMB1.

I'm all for recommending defence in depth, but please study changes like this before doing them.
When I was teaching calculus, I made a fundamental decision of how to define limits:

I used limits of sequences.

In our university, we encounter limits in either a handwavy way in Calc I or an epsilon-delta way in Advanced Calculus. Sequences and series are introduced in Calculus II.

Continuity is then described in the same terms. Or perhaps in terms of open sets if there is some topological topic.

I think this is pretty terrible for intuition. Not just that, but it's not even general enough - it requires normed spaces, so then you have to generalize again.

Much simpler to talk about ancient Greeks and Zeno's paradox. And then rigorously define limits of sequences, and define limits of real valued functions in terms of "for any sequence x_n that approaches x, y_n = f(x_n) approaches y". Simple and right away lets me show counterexamples beyond "left and right limits", like cos(1/x), and show students how to produce two sequences that converge to different numbers.

There are similar ah-ha moments when discussing fundamental concepts of linear algebra, number theory, complex numbers etc.

The two best books I have ever found on teaching Complex Numbers are:

1) Bak and Newman

2) Schaum's Outlines

They actually give you the understanding and ceeling behind WHY analytic functions are the way they are, and derive holomorphic functions from that. Imho a more terrible approach is that of Serge Lang and proving everything the other way, with Taylor power series.

Bottom line - make a directed graph of how you will teach your subject and then figure out the best entry point an direction for the greatest cohesion, as you would when telling a story.

If you are curious, now I teach a course on "Thinking Matematically" and here are this semester's results of that approach:

Not a requirement that you participate in Kindle Unlimited to sell Kindle ebooks, but Kindle Unlimited requires Amazon exclusivity. (I could have worded that comment better.)
I rescued a bunch of these after they were thrown out by a hospital for which I worked. Absolutely fantastic little machines; they run OpenBSD or your average GNU/Linux distro like a charm.
I feel when it comes to motivation in math, I just want to know why people got so excited about a particular theorem in the first place. I'm ok with the answer "before this theorem we assumed all these different things we proved in similar ways were different. Now we know about their commonality and it allows us to borrow mathematical machinery and use it here".

For example, take something like measure theory. A reasonable motivation for measure theory to me is remembering your introductory probability class how you had to learn a probability mass function for discrete spaces and a probability density function for continuous spaces. Now these two ideas are obviously nearly the same idea. I mean the notation used is a pretty big hint. But you need measure theory to have the right concepts to describe how they are the same.

Where are all those kinds of motivation for things like topology and cohomology?
This and Stallman's "Right to Read" (posted yesterday at https://news.ycombinator.com/item?id=14332257 ) are particularly relevant given the whole WannaCry situation --- no doubt there will be plenty of authoritarian-minded thinking computers (and maybe even programming them) should be locked-down/regulated more, to stop such attacks.

In some sense, I rather take solace in the fact that hacks, attacks, cracks, leaks, etc. are continuing to happen regularly --- they are a sign that there is still some freedom left in society. "Imagine a world without crime" is a somewhat common phrase used by some, and if you actually do, you will realise that it would pretty much be the world of Orwell's 1984: there is no crime because there is no more freedom of thought nor action; everything has become under the control of some central authority.

This goes beyond computers, although they will be a large part of it; it's really a general war on freedom.
But there seems to be active distrust of coders working solo, both from managers and from other coders. There's a surprisingly strong perception the "a team" is the safe option.

It's been my experience that capable developers tend to appreciate other capable developers. It's also been my experience that capable developers appreciate managers who are actually doing a useful job, and vice versa, and that both of those groups are also quite willing to support those who are currently less experienced but are interested and trying to learn and grow.

I suspect the kinds of objections you're thinking of most often come from managers or developers whose own positions are threatened as soon as someone competent enters the picture. A capable one-person development group has no need of a micro-manager to take the credit on their behalf, nor of a developer who has just enough knowledge and skill to be dangerous and/or in the way but no inclination to get any better.

At some point obviously you need more than one developer for scalability and resilience, but even then you can still do a lot with a few good developers and a useful manager co-ordinating them compared to a large group of mediocre developers and a whole management hierarchy above them.
For once I hear some positive non-tech related news about Amazon. Bravo!
What do you see as the build vs buy preference here? Are you better off being Uber and investing billions in self-driving technology (assuming an ideal world with no lawsuits or misconduct), vs Lyft partnering for the same features? Frankly, I don't see the advantage of a software and logistics company going off on a robotics and AI track. Self-driving will take decades but eventually will become commodity technology.
You not getting p0wnd is an example of the shareholders of the owner of the machine, and the interests of the data input substrate (you), being aligned.

You get this security in exchange for all your personal data being uploaded to their servers (for advertising to try and change your behavior for their clients, and for storage for your government, and perhaps others), and Google getting to decide which apps you can run, and which apps developers can publish in the store.

As long as you stay aligned with the interests of the shareholders of the ad-surveillance company (and the government) it's a great deal.
> I've also heard more than once that Lyft customer's tend to be more well behaved in the car for whatever reason.

I have also heard this as well from lyft drivers and I am very curious as to why
Do you want insecure systems, massive fallout from leaked pwning tools and thieves taking the world prisoner? Because the NSA's strategy so far is how you get insecure systems, massive fallout from leaked pwning tools and thieves taking the world prisoner.

I wonder how the dialectic will play out in a worst-case scenario if we get to that point.
Please distinguish between federal-level procurement and state and local procurement.

"Instead of actually going with the lowest bidder .. " In many states, it's law that they must go with the lowest bidder. This often causes problems because that lowest bidder delivers shoddy work that leads to eventual cost overruns--going with the "best value" instead of "lowest price" would reward companies that could meet both cost AND quality expectations. It'd also more closely reflect private sector considerations if those laws were changed; a private company can spend more for higher quality and get the long-term benefit of that quality deliverable, and that's a trade-off and decision that's simply taken away from state/local procurement professionals.

State and local procurement tends to run pretty lean, and tends to be pretty accountable. All this stuff is public record, and local papers will often cull through that stuff looking for juicy nuggets. The relative rarity of public purchasing scandals, at least for state and local folks, tells you that they're probably doing a pretty good job (even with the goofy restrictions like "you must buy from the lowest bidder even if their work is shit").
New York: drivers have lyft and uber apps/logos running/displayed.
Laudable. The math on the space is a little odd though.

"47,000 sq. ft. of space within Amazon’s newest headquarters building as a permanent location for a Mary's Place Family Shelter. This first-of-its-kind partnership will include 65 rooms, which will shelter more than 200 homeless women, children, and families"

235 square feet per person? That's a lot of room. Maybe only some of the space is being used to start with? Or a fair portion is for some sort of separate administrative staff?
Depending on the particular model, cooling may not work properly.
Yeah, it was poorly worded. I just meant it is difficult to have fun because of the expectation to entertain people you are around.
What we really need to be concerned about is how a party that runs entirely on being completely opposed to everything the American people want has taken control of the entire government and how it intends to maintain said control. I'm encouraged that now that the Republicans are trying to kill women, children, and the elderly by taking away their healthcare, that some people are finally losing patience. A few people. Mobilization behind net neutrality is still a million miles away from now, where people face the united Republican political and propaganda machine literally trying to murder them and say "well, we probably deserve it".

A secondary concern is whether it's appropriate to use the word 'democratic' to describe anything about the United States government. Happily that concern is easily dealt with: the answer is 'no'.
stackoverflow nazis; this should not be a closed question
It also has terrible video with Windows in my experience. Good enough for an RDP or XenApp session, sure, but not much else.
Ignore the title, because the questioner is not Bernie Sanders. But this Milton Friedman response to this very question answers your question pretty succinctly.

I have often thought of this as well. One option is that they still outsource the financing to local owners, not necessarily your traditional car owners, per say, but more like local companies that buy AVs and place them in service.

However, I think an interesting approach would be to use a traditional Project Finance scheme [0] to obtain cheap, non-recourse loans in order to acquire and deploy large fleets. These schemes are common for infrastructure projects, which occasionally amount to billions of dollars. Under such a scenario, then the actual owners might end up being entities familiar with setting up these deals, and Waymo et al selling the technology/cars/platform (arguably of higher margins).

h.265 (HEVC) compresses fairly differently, the modes and fallback methods are also better the higher the detail (dimensions)... with x.264 (AVC) you get pixelation, with HEVC you get blurring... for a 1080p or 4K output, this is MUCH more pleasant to watch and allows for some shortcuts that aren't as noisy.

One of the first things I noticed when first seeing DirectTV and DVD quality, for example was the pixelation of things, usually in the background... to this day it sometimes distracts me... that alone is about enough for me.

The way regions are selected for compression is also better, but I'm not into the technical details enough to explain well... all I know is I can get about 5/3 to 5/2 more content in HEVC while at an equivalent or better quality. So yeah, it's a big deal...
There is no comment which is improved by a call to downvote it. It's also explicitly against HN's guidelines: https://news.ycombinator.com/newsguidelines.html
Really ? Because this is trivial to make using a microcontroller. Or you can use any FT232 serial interface.

I mean I'd think you'd prefer an arduino for this application over pretty much everything else since you can quickly upload small programs to the arduino that keep the "fast" logic on the arduino.
If we're not extremely careful about it, it may not become commodity technology, it may rest solely in the hands of a few companies who maintain full control of it.

All it would really take is a few big successful players who are behaving like Tesla (you're not allowed to use self-driving for ride sharing) and a few nasty failures from smaller players before regulators crack down and say "okay, you now need to meet these extremely stringent guidelines and provide an enormous sum in insurance" which would basically inhibit competition. It's a nasty mix of capitalism and regulation that can kill a market before it really starts.
No.

For the benefit of other folks doing capacity planning: expect peak load of ~25 requests per second [+] in the first few minutes after your thing hits the front page and 50k~80k sessions over the course of a day for a typical article-style UX, coming both from HN and Twitter/etc assisted magnification of HN articles.

[+] For your HTML; you'll of course get the usual multiplication for linked scripts/css/images but you'll come nowhere close to saturating your uplink with those, so the limiting factor is almost certainly processing time for dynamic requests.
I tend not to buy stuff I know I'll only use once a year, if I can avoid it. I'm in a relatively small (by american standards) apartment, and would rather have space for a new kitchen gadget, which I also avoid at this point.
I find that Lyft has more consistent service availability than Uber in the Bay Area. If I have to take an early morning ride to the airport, I have had near 100% failure rate with Uber (maybe 1 or 2 times Uber has worked for me in that situation), and 100% success rate with Lyft.
I find it amusing that you call it "user experience", a very computery/hackery term for mathematics. There are so many computer-like expectations for mathematics that I see on HN. :-)

Anyway, yes. Every mathematician I know acknowledges that frustration is the natural state of affairs. If you're not frustrated that's because you haven't been doing enough mathematics yet. There's always a bigger problem, a new concept to master, a new way to look at an old idea.
I recently obtained a copy of _Authority_ by Nathan Barry, which seems great so far.
I'm curious where Tesla fits into this scheme. In terms of road miles, I reckon Tesla would have Waymo beat easily. They have far too many cars on the road and thus, way more data.

Does this factor into the quality of self-driving tech at all?
A raspberry pi with external HDD running is about 5W. That's 130 kWh less than a FX160 over an always on year, or $27 at average Australian energy prices.

Sure these servers might be handy for some things, but the Pi still has a lot of advantages. For me it's small form factor, low power consumption and GPIO.
Are you using accelerated video decode? 1080P should be no problem for just about any Intel iGPU made in the last 5 years or so when using vaapi.
Partner with and then have steal intellectual property from, you mean? That's a precedent Google would like to have set. It's like a public hanging of bandits.
Here's a google spreadsheet someone put up the last time other options were talked about https://docs.google.com/spreadsheets/d/1TCugLk0GSukeWjhsLu73...
At $2.8 B annual run rate, they'll be out of cash around 2018/2019, depending on their credit.
The lifetime of a vehicle is better expressed in terms of miles, not years, and for most models probably ends up being close to 200,000 miles. While a generic vehicle owned by an average family will take 10 years to reach that, a for-hire vehicle gets quite a bit more mileage.

One expense that people tend to leave out is the cleaning, both on the inside and outside. Someone has to take care of those car washes, and while cheap, they add up.

With the driverless model I see those expenses increasing, as without a chaperon passengers are more likely to eat, drink, puke, and in general misbehave (source: I've been inside some BART and LA Metro cars).
And I imagine after answering that question a few hundred times it might take on a level of kafkaesque absurdity.
Well all except the Surge pricing. That at times can feel like highway robbery.
Yes, agreed. Your use case was interesting to me in the way that you bootstrapped the problem. If only more domains were like that!
From your source:

"Customers who are running supported versions of the operating system (Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, Windows Server 2016) will have received the security update MS17-010 in March. If customers have automatic updates enabled or have installed the update, they are protected. For other customers, we encourage them to install the update as soon as possible."

If you don't have the update, you are not protected, you are vulnerable.
The recent cumulative rollups should include it and should be clearly labeled.
Uber has monumentally pissed off its driver pool in India. They came out with huge incentives, told drivers that if they "invested" in the company by buying cars, they would benefit even more.

Now there are drivers who bought their cars and have car loans to pay. But Uber stopped the incentive spigot and suddenly drivers are earning half of what they were making earlier.

Most drivers I speak to here are struggling to pay off their car loans. Some have resorted to sleeping in their cars and driving 12-18 hours a day just to make ends meet (not ideal for drivers or passengers).

The moment someone comes in with even a remotely better offer, most of them will jump ship.
I use Asus 1001PX subnotebooks that way. They're available for about $40 on eBay. You get a keyboard, screen, WiFi, Ethernet, 250GB hard drive, and USB ports. Usually a power adapter, too.

(Only use the real ASUS power adapters; the no-name 3rd party units overheat, don't provide enough power, or in at least one case, catch fire.)

When I get one in, I put in the Xubuntu USB stick and run the memory diagnostic for an hour. If that passes, I wipe the machine completely and install Xubuntu 16.04LTS. Works fine. All the peripherals are supported. (There was some trouble with 14.04 LTS; the infamous "disappearing cursor" bug affected these units, because they had a certain model of Intel graphics processor. But that's fixed.)

I use one with a $30 USB microscope to help with surface mount soldering. Others run antique Teletype machines. One is used as a normal laptop.
Thanks! I haven't thought of content reviewer but that makes sense. The only issueis that the reviewer would have to know both Finance and Technology, similarly like myself.
Its interesting.

But honestly, there are so many components that sound similar, so I dont feel we've truly gotten to something fundamental here.

My first thought is to start with a Fourier, and then look at dimension reduction from there.
As an aside, the research on ego depletion that he quotes in uncritical terms has been completely discredited. The phenomenon does not exist. Of course, to know that you need to read science blogs, not books. But there are books about ego depletion, several, filled with lies. When the container is more important than the content, I suppose truthfulness is a secondary concern.
You may want to check out the rapidly growing number of RPi clones... cheaper and often more powerful, besides still having GPIO pins. You can find a nice list of options on the Armbian download page: https://www.armbian.com/download/
