Amazon does, but I find their results rather wonky at times. Filtering by rating works fine, but sorting on price seems to rarely work right -- they are often way out of order. Also filtering on price doesn't seem to work very well either.

On this, I would guess the price range categorization makes that more absolute. I would play with it more but I don't really have time right now.
Generally people with extreme gifts or talents (and specifically the 2 examples you mentioned) find passion in their skillsets so the argument that they should do that anyways is somewhat unnecessary. And the ones who don't most likely have legitimate mental issues that would prohibit them from contributing at a consistent level. Of course there are deviations, but physchological studies have more than adequately shown the large deviation of mental stability in truly gifted individuals.

My argument is made for "normal" people.

And I don't think your opinion falls in the realm of socialism, fyi.
She is a teacher but as you expect she is not a statistician. If she would have studied statistics in statistics department for a year she would know what to teach. First you start with a coin, you have 1/2 chance to get this and that etc. This means 50%, then you repeat your move 100 times and you say see, the output is 53/100. Then you repeat and the output is 502/1000. So they start to get what 50% means. Then you do it with die and so on. However she has started it in wrong way. And I'm sure that most of the kinds do not know what 50% chance rain means.

Maybe I don't want to become an anonymous number for tracking reasons.

Anyway, maybe your particular company is all nice and responsible, but if so you're hardly representative.
This Algae Battery Could Power A Tesla With 200X The Charge
Very clever to arrest him after the elections. Before the elections this would have been a much bigger issue and possibly would have gained votes for the Swedish Pirate Party resulting in more seats in the European Parliament for them.
What is evil about this?
Many of the problems in the computing industry come from efforts to deny the reality that content can't be protected beyond the audience's willingness to be honest.

And that's where the entertainment industry's efforts to brainwash people ("you wouldn't steal a car") and to make copyright violation a criminal offense (the longer the sentence, the better) come in: they are all efforts to try to make people so afraid that they'll be honest. What a way to treat their customers.
Which probably means Lenovo has no interest in buying the factory and Google will have no use for it after the sale
Does anyone know why they're using a full-blown (possibly old-school) camera? It seems like something digital would have been inexpensive and straightforward to use, and would have fewer moving parts.
At a senior level in the places that I've seen, I'd expect a mix of very abstract as well as more practical questions.

The other responses show some of the more algorithmically based practical questions. Things like fizzbuzz, quickly followed by how you'd do an in-place string reversal, followed by whether you'd use quicksort vs mergesort for something. Personally, I don't see a huge point in too many maths-based questions because Google, so it's a litmus test and not a skills test IMO.

Then there are language and framework related questions - maybe you'll get shown some complexish code and be asked to spot the bugs. Or you'll get asked how, in practical terms, you'd go about achieving something (with which library would you be working). This would also go over the technologies and skills you might actually need to have to do your job at the company.

To see the cultural fit, they might ask about a project that interested you, and why it interested you. I come from a government town, so this question winds up being pretty awkward, but a lack of passion and enthusiasm is something that I've seen technically-relatively-competent people turned down for.

At a higher level, there's things like "say we wanted to create a link shortener, how would you go about implementing it?" and the follow ups on scaling and asynchronous processing ("what about analytics?" etc.) Stuff which gets you talking in terms of the components and how they'd interact in terms of queueing, designing for reliability etc etc. These types of problems really have no wrong answer, and you can learn a lot about how the developer thinks, their areas of interest, and whether they'd be a good fit for the team without ever getting them stuck on a problem.

At the end of the day, I haven't asked/been asked, questions that are that different from those that you'd ask a junior or intermediate interviewee, it's the detail and quality of the response that you expect to be different.

That said, with 3 hours, they'll probably have the interview and then get you to code something.
Each company is different, I could be way off the mark, and 3 hours strikes me as a little short for the standard format.

A common interview format will have you doing multiple, separate interviews, usually 60 minutes long, with different people. The purpose of this is to gather a few independent opinions. You might be asked to write code, you might be asked to sketch architecture, you might be asked to tell war stories.

Try to stay relaxed, be candid, and take a break/drink/use the restroom between interviewers. Try to start with a blank state, mentally, for each round. Also, bear in mind that if you're breezing through the interview, people will often start asking tougher questions to try and figure out where your limits are. If, by the halfway mark, you're being asked things you don't know the answer to, that does not mean you're failing. (Avoid bullshitting if you reach this point, it'll be obvious and count against you, it's worse than just saying you don't know)
> I thought that the speed of electricity, actually electrons in a cable for a consumer use was around 1cm/s.

Folks who worry about the velocity of electrons when discussing the velocity of signal propagation in a coax cable have not fully understood Maxwell's Equations.

The fields are responsible for the propagation, and the geometry + dielectric determine the speed of the fields in the cable to first order. If those fields were in the visible, as they are for some fiber, then folks would talk about the speed of light in the coax. Since they are not in the visible, we talk about the speed of the TEM mode instead.

EDIT: Some other folks are pointing out that the speed of propagation in coax is about 2/3 the speed of light. This has nothing to do with the velocity of electrons in the metal.

Most coax has a central conductor, an insulator (made of teflon PTFE), and a outer conductor (the shield). The speed is almost entirely determined by the index-of-refraction of the teflon, which is approximately 1.5. The propagation speed is 1/index (approximately), so the the reciprocal of 3/2 gets you to 2/3.
It's the Ragusnik problem on a different scale.
I think that's how Twitch works by default now. They archive the whole stream for like a week so you can Highlight it, and then it's auto-deleted (unless you've configured it to keep everything).
At the same time you have to consider that this isn't new, as already pointed out.
That is not football. It is Egg Shaped Handball.

They use browser certificates (I'm not sure if this is the right name), which is actually pretty cool. When you create an account, a certificate is generated in your browser, and then you can login with it.

The big problem is that since it's almost not used, browsers implement it but haven't done any job in making it user friendly (for example, you can see the certificates currently stored in your browser in Firefox by going in preferences > Advanced > Certificates > View Certificates > "Your certificates" tab, not exactly user friendly). Also (if I remember correctly) StartSSL implementation is not the nicest one as well, as you have to keep your tab open while they validate your account.
This article is really clutching at straws, the only semi-tangible example of match fixing given is a supremely unimportant friendly between Guatemala and South Africa.

It also hints at "targeting" of a match between the footballing minions of the USA and Australia, without actually suggesting that the targeting was successful.

It's far from ideal to have footballers or referees from these countries engaging in match fixing, but these are very minor nations in the football world and it would have no affect on the important results of the World Cup whatsoever.
Why BSD over Linux? And which BSD would you start with?

I'd stay far away from SELinux, knowing that added complexity is unlikely to add security in practice. But is any of the major BSD kernels appreciably simpler or more secure than the Linux kernel these days? I'm sure that the Linux kernel has broader hardware support; that would yield an OS that more people can actually run without restricting their hardware choices. So on balance, Linux seems to me like a better choice.

To be sure, I'd strip down the userland, starting with the C library; I'd choose musl over glibc. Actually, my idea of a "trustworthy", "hardened" Linux distro would look a lot like Alpine Linux (the in-development musl-based version).
It's nice to see the Sherpa getting some acknowledgement.

I never understood why, when a rich white dude pays tens of thousands of dollars for a bunch of other dudes to scout a path, clear out obstacles, set up camps and caches, and carefully escort him up a mountain, it's the rich white dude who gets the credit and glory. I mean, it's still a pretty impressive achievement, but it's not half so impressive as the guys who do it day in, day out for a simple living.
Seems nice. I wanted to just see the best products by category, but it wouldn't let me search for [blank].
Well, why not name names?
Math is getting the right answer. Statistics and probability is not exactly math. They deal with chances. So she is wording it in wrong way.

Also, I should note that at METU no mathematician major student was able to graduate from statistics department as minor. They all gave up. That's what our professors told us. That is why math and statistics are very different subjects. It is like math and chemistry or math and computer engineering. Statistics do not deals with math, it has its own separate topic.
Human Beings as a Model Organism
> It's about in which situations it's called and in which it isn't

My point was that those situations are not fixed forever. It'd be very easy to imagine e.g. MobileSafari starting to trigger visibility hidden when you switch to another app.
Honestly, I don't mind that Gandi isn't offering the cheapest option out there. My domain and my host are from Gandi, so it was a no brainer for me to get my certificate from Gandi. I didn't even check the alternatives. If it was a hefty price, say, like $50/yr instead of $12, I'd have probably looked for other alternatives but I'm happy with them so far and I like to reward companies that serves me well as a customer.
well, to be fair, nearly any storage policy change will smell that way.
I'd love to see something like SSH, you trust the self-signed certificate the first time, and then it's considered valid until it changes (but it should get treated differently from CA-signed certificates, your yellow padlock idea is great).

Then warn the user if the certificate ever changes.
> This doesn't surprise me. The whole academic publishing side of things is a royal pile of shit. Glad someone is calling them up on it.

The ACM, at least, allows authors to post copies of articles on their web pages. That's a not totally unreasonable policy (although the ACM Digital Library is pretty well locked down).

I completely agree that IEEE is evil.

Random fact: Peter Suber was my academic advisor in college! Incredibly smart and nice guy.

Justin.tv owns Twitch, which is recently rumored to be in acquisition talks with Youtube for $1bil. I don't think they're bleeding money at this point.
The marketplace disagrees strongly. Otherwise the cost of an angled measuring cup would approximate the cost of a nurse, which it does not -- the difference is at least 4 [decimal] orders of magnitude.
It is worth acknowledging that education tends to be an easy major at US universities because the public supporting public universities has an incentive to firehose students into a steady supply of new teachers. It's a wide funnel optimized against false negatives because the profession has a high attrition rate among recent hires.

I was talking with a freshly minted math teacher yesterday at the soccer field. He was as enthusiastic as one might imagine a 23 year old would be after a year spent with middle achieving suburban Atlanta kids in a 10th grade math class. His first response when I asked how he liked teaching, 'It's a job. It's not like my internship [in a university town] was.' He likes math; teenagers not so much.
What culture is that? I'm curious.
Vox interview with Tim Geithner
As a side note - you've single-handedly destroyed the layout of this article's comment page with this magnet link.
It's one thing to say "we're phasing this out over 12 months" (or even, say, six).

Two weeks is freaking desperation.
Would you mind putting your magnet link in a indented code block? The non-breaking string of chars is causing the page to go wonky.
This article is misleading. The fundamental flaw is that it's treating the causes of latency as a black box while enumerating several ways to ameliorate the causes of a bandwidth shortfall.

For example, suppose the reason your modem's latency is so terrible is that it's a software modem and the software is poorly written. If you use a more efficient algorithm then the latency goes down. Suppose the reason for the high latency is that you have a router receiving packets from a fast connection and sending them out through a slow connection, and the router continually has a queue full of packets that have to be sent in front of yours. In that case you can either increase the bandwidth of the slower connection so that packets don't get backed up in that router, or at least reduce the size of the router's buffer.
There are a lot of 'founder matchmaking' websites out there, but I haven't heard any good stories. Otherwise try the monthly Freelance thread here: https://news.ycombinator.com/item?id=7507753 or Toptal, Elance, etc.
I think we need to distinguish the road technology from the solar technology. Is this a viable road technology when decoupled from the solar technology? Is this mechanism of solar collection/distribution more or less effective than other efforts? Clearly, our paved-over world could be put to better use, but is this approach a net gain or is it just solar buzz?

Instead, start by deciding whether killing that person (and the collateral damage it will cause) is OK, and then use the most efficient means to do it.

Unfortunately, most calculations of whether a particular mission is "OK" will include cost and risk as factors.
The reasonable upper bound of benefit when designing a new OS or a new information-sharing medium is, a priori, much higher than the upper bound of a new measuring cup or a new dessert. So, this means someone entering those quests can reasonably state that they are tackling something big, i.e. worthwhile.
Very nice way to make some side cash by using amazon affiliate network. Just make sure you are following their rules to a T so you do not get the hammer and actually get paid.

I like the clean look and the blue load bar. I also like the results.
Yeah, Lenovo aren't going to get the same symbolic benefit from manufacturing in the US as Google did.
As it was said before, careful with what you are saying. That looks like a welcome email, which was sent as soon as you registered (password not encrypted yet) which is not a good idea anyway, but still, far from the security issue it would be if they were stored in plaintext.
Quite good for Google translate. There's some odd words like "kväljer" but overall the meaning is pretty clear.
L&W asks for copyrighted works of Marx to be taken down from MIA
The idea of this project was to (hopefully) include such a type-system in a future mainstream language (that was designed with refined types in mind, not an existing language with refined types added as an afterthought). I'm sure that libraries would follow if the tools became available.

Another problem, of course, is that SMT solvers are only a nascent field; Z3 is fast and supports many theories, but is not free (for commercial use), and other solvers (I tried Alt-Ergo and CVC4) are considerably slower and have much less features.
They also had to buy new servers a few times.

That's the wrong comparison: you have to combine the cost of ALL angled cup (possibly deduct the value of all non angled cup) and compare with the cost of one nurse, since the two scenarios are: angled cups vs no angled cup at all and one more nurse
I don't have any sources, but it certainly tracks with my experience.

For those interested in a longer analysis of what Amazon's relationship with publishers looks like, I'd recommend George Packer's article from the New Yorker earlier this year:

It is a thing!-- The Dell Venue 11 Pro sounds exactly what you want. There as a keyboard option with an extended battery providing the battery life you're looking for. Also a great 1080P display, replaceable internal battery, digitizer option, etc.
I remember trigonometry, I think must of us here do as well. You're talking about something. You're promoting this notion that kids should be uneducated because knowledge is useless and it's better to simply learn the lowest of material possible to help attain low-skilled jobs. This teacher is bemoaning the thinking patterns of kids, I think it is a very different issue.
This is because 'X is killing Y' is almost always a meaningless analogy designed to generate controversy rather than understanding.
Processing is a wonderful library/programming environment. An intro to programming class taught in Processing would be cool.
The Game That Conquered the World
Not sure if I understand your comment correctly, but I'd say that Heartbleed got noticed simply because it's a vulnerability that (1) affected a very large number of computers (the servers and consequently all the clients who connect to them) and (2) could have very bad consequences (TLS is one of the backbones of the internet).

Regarding this project, I know there are tools that help mitigate such issues, but unfortunately there isn't a single mainstream language that would really support this. I wanted such a language for a long time, so I (finally) decided to experiment with making one.
I admit it would freak me out to have the glass start cracking as I was standing on it. It really is an awesome view though, we stopped by on our last Chicago visit and you can't really help but clinch up a bit. Recommended if you're travelling.
I live in LA. This is more complicated than you think. Example: I take the bus, because, screw traffic. It's nicer and easier. We are at Santa Monica and Westwood and a cop car pulls up right next to me. I'm higher up, and this light takes a long time, so I get a good long chance to view the cop car over.

I was surprised. The damn thing was rusted to all hell. There was a thermal scanner on the top, but good lord if it actually worked. Most of the BNC cables (yes, really, like in freshman lab) were frayed up. The top was totally rust, and a bit of liner was coming through. Remember, in SoCal, we get rain maybe 5 times a year. This car was OLD.

The thing about LA cops is that they are sensible and responding to incentives correctly. The LA basin is gigantic and they have to patrol all of it. Add in the low taxes for police support, and you get the main problem of a street officer: Backup is 25 minutes away. It's just you and your partner most of the time. This, above all else, explains the LAPD.

The US Army ran into a similar problem in Iraq right after the fall. We became the police, effectively. Problem was, just like in LA, the area was too big for the force size. All small houses, all just sprawl, no back-up. Things started out just the same as in LA. You are FORCED, in order to protect yourselves, to be the Biggest Badass all around. You must culture a sense in the populace that you DO NOT FUCK WITH the US Army. Brutality is necessary. This is what the LAPD is doing, and it makes sense.

Thing is, Iraq taught us a lot about COIN, COunter INsurgency. What the army ended up doing, and it was much more successful, was you deputize the local leaders. Make them hash things out among themselves. Only call the Army when you really need them. They do not become a patrol force, but a real big hammer that whomps on things. Patrols are the job of local deputies.

The LAPD, being in California, cannot do this. The legal system here in the states will not allow for local deputations of people in Compton and Koreatown. Just from a benefits and payment perspective alone you can't do this.

So, the LAPD is doing the best it can to stay alive, which is the situation the taxpayers of LA county have put them in. You want less drones and a better police force in LA? Pay them more to get more people on the streets. Give them back-up. Then they won't be so brutal, because they won't be alone. Otherwise, drones and the like are here to stay
They're also designed to stay in one place, which is nice for offices vs finding that people have re-arranged them all over the place and a bunch are missing.

You can also hold a store of spare computers and spare monitors/keyboards and swap out ones that are broken, repair and then return to circulation. This would be harder and more expensive with laptops.

Bleeding money and being in acquisition talks are not mutually exclusive.
Because Trent Reznor is a big enough name, he can control the conditions of the contract. He also has proven he is willing to go without the studios if need be, which, for a known artist, is a huge bargaining chip.

Using him as a shining example is to be incredibly naive about how contract negotiation works. Nobody is saying that recording studios do nothing (just handling distribution is big), just that they suck out far more value than they provide for the average artist.
Works for libc.
Could be a challenge: write an IPLANG program with multiple "interesting" solutions
No you're not. You're just making up tore own statistics. If mathematician can't recite it quickly, she can certainly develop the formula. Really, trigonometry? This is pretty simple stuff. Is it that the surprising to some of you that there are "programmers" on "HackerNews" that might, at whatever age, still know such elementary mathematics?
