If you review the footage of the professor confronting the students, you will realize that this was not a publicly available test guide. This was a pool of test questions based on the material in their books intended only for the teachers of the courses to create the tests, not the students to study from.

They obtained the test blank using, at best, morally questionable methods (social engineering, purchasing them under false pretenses, etc). At worst, they stole the materials outright.

If they had used information that was legitimately publicly available, I would agree with you. However, they did not, so it was morally reprehensible.
I've never been convinced that the memristor is worthwhile to consider as a "fundamental passive device" as everyone seems to want to claim. There are a few reasons for this:

(1) It's underspecified compared to the fundamental passive circuit elements. For linear R, L, and C, each has one parameter, its value. Ignoring trivial cases (viz., resistors), a memristor has as its memristance an arbitrary function of V and I. As a result, any interesting memristor is automatically not LTI.

(2) It's not particularly special. Why don't we also define a memcaptor, whose capacitance is a function of its current history? I could easily do this, for example, by making a capacitor where one plate is attached by a spring to a fixed support; then, by adding charge, I move the plate and increase the capacitance (or, by removing, I decrease it). Oh wait, that's just a nonlinear capacitor. In the same way, the memristor is just a funny name for a particular kind of nonlinear resistor.

(3) It's not particularly practical (for the moment). It can't be made in anything but a very specialized, presumably extremely expensive process. I hope this changes---I'm sure it'll encourage someone to use them!---but at the moment this really limits my excitement.

(4) There's nothing I can build with a memristor that I couldn't build already. This isn't like the invention of the vacuum tube: you give me a memristance function, and I can build you a pseudo-memristor out of transistors, Rs, Ls, and Cs. Yes, it could be less {space,power,?} efficient, but this is not a quantum leap in technology the way the vacuum tube was (one could not, with 1890s technology, reasonably build something that emulates a vacuum tube).

I'll admit that strictly interpreting my last argument, the vacuum tube could be made to emulate a transistor and thus the transistor wouldn't count as a quantum leap---clearly ridiculous. However, I'd contend that the real value of the transistor was only evident once it was sufficiently miniaturized and its production was sufficiently cheap. You show me memristors that are six orders of magnitude cheaper than transistors and by golly I'll be a convert. Even then, it'll just be yet another nonlinear device with which we can do interesting things---and just like the transistor, the memristor will simply never be as fundamental as R, L, or C.
I don't know if "fake work" is anything new. I would imagine that fake work has always been around. That would go to show how little real work is necessary to keep things running.
That is exactly how I used it. I've since moved on to Pinboard in the great Yahoo! scare of '10 and am very happy there. One of my favorite features is emailing myself URLs from my iDevice.

I've never really cared what others are bookmarking, as I've found Google has traditionally been just as good as a big group of anonymous people at telling me what to look at.

Cross-link that with people I follow on Twitter and it might get interesting, though...

Alarmists and lawyers (with help from the panic perpetuating media) thrive in this climate:

"Christina Gagnier, a lawyer specializing in privacy and copyright, said in an interview last week that there wasn’t enough legislation to protect people online."

And to hell with innovation, lets make more laws that insure lawyers get paid more.

If things were only depended on lawyers and privacy fundamentalists we would still be living in the middles ages (EPIC contested that Gmail was illegal when launched).
I think because Yahoo did not keep updating delicious that these other serves took hold of each of the niches out of delicious. While each of the other services that you mention has their own strengths, I miss having the ability to tag something with multiple tags to better sort things into different categories.
If you're smart enough to steal 75 million credit card numbers, then you already know about the forums where that information gets bought and sold. You start selling the individual cards, not the whole data dump, and it's the buyers that are starting to use those numbers to make purchases.

If either of those has sex with me without my consent, then yes. I would call that rape. Who in their right mind wouldn't?
Great project; I remember implementing a scheme interpreter in scheme back in undergraduate. It gave me a great understanding for scheme.
Thanks for your thought and true, the name isn't everything. But I think that a good name sure helps, especially when it comes to marketing. Color probably get a lot of traffic from being nr #1 on Google search for "color", but if you don't want to spend huge amount of money, colorapp.co or colorapp.com would probably work great as well. My point is, the name matters and adding two or three letters to a good name is better than having a short and snitzy but hard to spell name.
> This is a semantic quibble, but I disagree that objects in JavaScript are any less proper OO just because they are implemented as associative arrays. JavaScript is a fundamentally OO language in a way Scheme is not - for example all built-in types in JavaScript are objects with methods.

Not even a semantic quibble - more like me poorly expressing my typical use of objects in JavaScript. I agree - objects in JS are full objects. I just tend to limit my use of them to the associative array realm...

> I think OO is getting a bad name due to people annoyed with Java, and functional is hip these days.

Agreed. I've written ~250K lines of Java (real-time, highly parallel and concurrent systems with hardware accelerated UI) in the past 3 years and love many things about the language and (especially) the JVM. FP is certainly in vogue right now - and for mostly good reasons. Hopefully as the pendulum swings we'll end up with a healthy middle-of-the-road approach which incorporates OO and FP. After all, closures are a poor man's object and objects are a poor man's closure.

> But JavaScript is still an OO language.

Most certainly! I was just highlighting the ability to (mis)use it as a functional language. Though as a functional language its lack of immutability is a double edged sword...
Do you use Mac? It seems writing a script would be easier for Mac. I can try to cook one up. I will post it here if I succeed.
Things take time to play out. Plus, physical CDs are still pretty popular it seems.
I'm in a very similar situation - I have been working for many years, and seen both extremes of salary transparency, but am still unsure about the best approach.

I started out in a very small but rapidly expanding software company, where the founders encouraged everyone (including themselves) to be very open about salaries. This didn't work too badly because most employees were recent graduates and no-one was earning much money. However it did generate some dischord when it became apparent that those from less prestigious universities were getting paid slightly less.

A few years later I was working in a very large corporation, where (like you), HR hadn't secured their data very well, and I got to see details of many thousands of salaries and bonuses, including those of some of the highest paid people in the UK at the time. Without going into too much detail, the remuneration disparities were staggering. I think it is fair to say that it was the sort of company that was prepared to pay as much as necessary and as little as possible. If the scale of inconsistencies were widely known, I would imagine it would have created a fairly toxic working environment.

So in the end it might come down to company size and culture. I can't imagine why a small coffee shop, like in the original article, would want to keep it so secret though.
What kind of tutorial would you like to read?
> I don't know why the title was changed.

The HN guidelines ask submitters not to change titles except when they are misleading or linkbait. Accordingly, we often change an edited title back to language used by the article itself—usually the original title, sometimes a subtitle or other heading. One reason for this is that we can't judge the accuracy of most edits.

HN titles also tend not to include the names of authors or speakers. We learned years ago that the site works better when emphasis is on content, not personalities.

(Submitted title was "SpaceX's GPU-Powered Combustion Simulation – Adam Lichtl and Stephen Jones")
The author doesn't make the case for why these types of reasoning skills are important, or why IQ is important for that matter. This isn't the first time that I've encountered brain teasers, and I know that I dislike them because I generally suck at them. The author characterizes this as being a "cognitive miser" (I also hate it when people make up terms), or not putting forth the effort to thoroughly think through the problem and just going with the easy answer. I can accept that this is what's happening, but what the hell does it mean?

Should we be hiring people who are good at brain teasers? Does that kind of thinking indicate the ability to ship products, come up with novel solutions or understand things in a way that leads to significant increases to the bottom line? In my experience, everybody is some kind of stupid. Even puzzle masters occasionally lose their keys or say embarrassing things at parties. Intelligence and the lack there of is so fractured and interconnected that it doesn't seem like any kind of test is going to be able to measure it accurately, or even nail down what 'it' is.

Some of the smartest people I know were good at questions like this, or maybe I just think they're smart because they're so good at these questions. Big companies love to use them during interviews and there's probably a reason for that. It's definitely a skill I would like to improve myself, but I still don't fully understand the value. Life isn't a series of puzzles, it's a series of problems punctuated by sheer randomness. Being able to take this or any kind of test can't be highly correlated with "success" by most measures, and certainly not in the ways that matter to most organizations.
Hold Hold Hold Abort :(
There are absolutely some industries where this makes sense (life-saving health care, national defense, things like Amazon where you literally stop making money when things go down).

90% of developers don't work in these industries or on these types of projects. Hell, I work in healthcare, for a private company, and there is zero reason for any of us to be on call. Patient quality doesn't suffer one iota if our software is down, which it rarely is.

It really sounds like you're advocating that developers be on call to "fix" the "problem" that there's no reason for them to be on call?
Imagine we collected the best material in written, bound volumes. And nearly every city had a large collection you could borrow from for free.

We did. The professors of history, psychology, art, biology, math, - everything - at the world's greatest universities very often write down what they know in books. We achieved this already.

You can read Feynman's course on physics tonight. Your city library probably has it.
Did facebook drop Cassandra completely? Or do they just not use it for the messaging part?
Thanks for the Notational Velocity suggestion, it looks nice (link: http://notational.net/).

The extraneous Japanese writing on their page is unbelievably tacky though. I can't figure out what they were thinking. Was it supposed to look cool? It just says mundane things like "Download" or "How to use the program." Not a good impression...
I would hope it would come out of the bonuses for the senior managers responsible for the relevant department.
Perhaps you're not optimizing your titles as well as you could be....TechCrunch did just sell to AOL so they must know what they're doing!
>update the included web browser on Windows or OS X without waiting six months

You can already do this in Ubuntu and variants by adding a ppa (personal package archive?).

Also, at least on Kubuntu, the 6 month cycle isn't preventing releases that bork a lot of peoples systems. Latest one was broken from the off as not all files were uploaded to the archives and then the nVidia drivers clashed with the desktop clock (!).
On linux and before discovering NV I was always snapping back to plain old vim (one big text-file).

It's been years since I switched to OSX, though. Perhaps there are worthwhile dedicated apps on linux now (back then I didn't find any).

I linked to that link, where you can see in the first graphic that in 2019, 22% of U.S. adults use Twitter. (73% YouTube, 69% Facebook, 37% Instagram).
they don’t sell anywhere close to “more EVs than anyone else”.
Preparadigmatic.

I find current conference proceedings on AGI to be incoherent, much worse than Fuzzy Logic conference proceedings from the 1990s, except Fuzzy Logic has established uses in the control field and AGI is almost undefined and has no uses.
Is that honestly what you derived from "While Google and YouTube paid $170 million, in another COPPA case settled this year, the operator paid a total civil penalty of $35,000."?

I know hacker news encourages us to assume the best intentions when responding to comments, but I'm finding that difficult to do when a $170 million COPPA fine was levied by the same agency in the same year, mentioned in the same sentence as the $35,000 fine that you derived your tidbit from.

I'm confused what private entity wants this? Old media?
I've used Hugo for a while and was drawn to its single binary, quick builds, and nice template features. However, after a few years I've decided that it's not for me.

While the Hugo developers are very responsive and do a good job maintaining the project, they don't generally respect their users (be they theme or site developers) time. Every few versions I find that my sites are broken because the developers changed something on me, sometimes in ways that just silently change the behavior of the site (as opposed to a build error, which would be annoying but which is more discoverable).

The documentation is also very difficult for me to learn from. Despite being extensive, it's extremely hard to learn how to do anything and I find that it frequently makes assumptions that you already are an expert theme or site developer. I wish I had a better grasp on what makes their documentation so hard to use despite the fact that there's so much of it, but I find that what I'm reading is almost never what I need to actually understand what's going on. This might just be me though.

Do people "use" bitcoins? Right now it seems like something your betting on will eventually be useful.
While the nuclear family most common for most of recorded history, since reading Sex at Dawn and a few related books, I've come to believe that for most of human history -- that is, hundreds of thousands of years before agriculture -- we lived in communities where all adults helped raise all children.
I've seen this pattern at least 3-5 times recently, at either the beginning or end of the series. The dirtiest one imo, is letting someone get to the 3rd or later interview with nothing more than "thanks ttyl" when they say no or cancel. It burns me out. Most recently it was a series of 6 interviews across 3 stages. Only after I responded to their automated rejection by emailing each of them personally, asking for feedback, did I get anything.
If it's environmental impact justifies making it illegal what else could potentially be on the chopping block with the same logic?

Videogames also run GPU hardware full pelt, so does creating the majority of what you see on the screen for a Marvel movie. How much of the worlds resources are burned daily encoding video for social media.
Your first link seems to imply that bandwidth use is the same as data center use. YouTube and other streaming platforms are generally served from edge locations and use last mile bandwidth and do not constitute large CPU costs when compared to bandwidth.

This comparison is almost certainly off by orders of magnitude.
It seems like you believe bitcoin has absolutely no use at all. Why would you think that?
Estimated Bitcoin energy consumption is 1.8% of total US energy consumption. I don't think that printing and circulating US dollars even remotely adds up to 1% of the country's energy usage.
I'm comparing D3 with two of it's progenitors, Prefuse and Flare. All of this is coming out of Prof. Jeff Heer's viz group at Berkeley.
slightly tangential, but I wonder how they would/could treat sterile medical equipment (insulin vials, syringes, epi-pens, etc).

It's not something that's exactly conducive to hasty disassembly and swab analysis.

I suppose the paranoid approach would be to confiscate it on any suspicion, and require you to purchase/be credited with 'certified' replacements post-security, although I'm sure there are exotic things that would be tricky to get everywhere.
I believe it's to encourage the projects Kickstarter funds to have a specific focus, and to decrease the likelihood of fraud. If the money just goes into a slush fund, it's easy to lose track of it.

For instance, the Syzygryd Kickstarter is to fund our flame effects. Our money is earmarked for prototyping and fabricating our flame effects, and any money left over goes to buying more propane for more flamey goodness.
If I like a site, and they don't show obnoxious ads I often white-list it. It's up to you convince me.

I don't get how pornhub still exists considering it hosts so many illegal videos: assaults, child porn, spy cams, etc. and this is the premier porn site. imagine what you can find on less mainstream porn sites.

the US gov went full on war against torrent websites and closed every one of them no matter how small, yet this giant website that literally hosts rape videos is OK.

all providers of PH should follow VISA and Mastercard and cut ties. I realize killing PH will not end sharing of videos but at least there will be a lot less money made from it and a lot less viewers.
One edge-case I've noticed with Apple's subscription billing and heard other people talk about when implementing billing systems is changing currencies/countries. Apple, in line with most people's expectations, when you cancel a subscription it doesn't cancel immediately and prorate a refund. It just stops future billing and lets you serve out your remaining cycle (gyms and other meatspace places do this). The problem is you then have to wait until your subscription expires to transfer your account to a new country/currency.
>it is fairly easy to make the gauge narrower by removing the nails and placing them back at a narrower position, something Germany did during WWII

This doesn’t sound like it stymied the Germans much. Also look at the answer here: https://history.stackexchange.com/questions/23616/what-did-g...

Do you need anyhing else to get convinced?
>> but that's quite different from a web server that can usually be scaled horizontally pretty easily

So a lot of the other responses are comparing it against Rails and the like, but it sounds like you may be asking specifically around scaling.

Erlang (and by extension, Elixir), is nice even when scaling because the actor model will scale to I/O or CPU bound workers simply, without having to tweak threadpools or worry about thread starvation or etc. Other languages that provide n:m concurrency here have the same benefit though (i.e., Golang).

Where it shines in comparison to those is in its fault tolerance and memory model. Immutable non-shared data + supervisor hierarchy gives you tools to tackle state that are less error prone than most other languages.

And the fact it has a Rails like environment in Phoenix (and Plug, and Ecto, and the whole ecosystem) means you get the same quick-to-build app functionality, without giving up the performance and state management.

It's basically having all of these that make it desirable on this front; you can write code as quickly and simply as in Rails, getting the braindead simple scaling behavior of any actor/CSP based model, with the state management of an immutable language, and the fault tolerance of Erlang.
Perhaps, but is it really all that surprising that something not merely said but broadcast to the entire world is remembered in perpetuity?
Do not believe.
Interesting quote from a company providing such services:

"The Remote Health Monitoring System is the IT backbone that supports HealthFrontier’s entire portfolio of solutions, including the ecg@home™ and the microtel™/ecgAnywhere™. It captures data transmitted by the patient through USB, Bluetooth, or trans-telephonically. The RHMS™ then stores the information in a database, which can be accessed by the patient’s doctor through a web-based interface. Benefits include:

Cloud computing: The RHMS is hosted on a network of servers across the US, which increases reliability and eliminates the need for a large capital investment in on-site hardware and maintenance."

Could you add an option to make the y-axis have a logarithmic scale?

Some results have hundreds of thousands of results for 2012, but only a few for other years, so it's harder to see a pattern.
I'd like to see more back story first. Medicine is about risk management. There are places where you need 1/100,000 reliability, and there are places where you need 1/1000, and there are even places where 1/10 is good enough. There are primary systems, and there are auxiliary systems.

Without any background, it is really tough to tell where this fits. You can't blame the people for making the wrong decision until you know what the risk profile for the failure is.
