> This is where you're wrong. Not everyone is as happy as they could be. If there were no price discrimination then the theatre would make more money charging £7 to all 20 adults and 10 students (£210) than charging £10 to only the 20 adults (£200) and having ten empty seats.

No, I'm not. For one thing, I picked £7 out of thin air. Change it to £6 and this (erroneous anyhow) statement falls apart. Moreover your analysis is wrong - not everyone is as happy as they could be, you're only thinking from the consumer's perspective. The cinema could have made £7 * 10 + £10 * 20 = £270 so in your "best" case for everyone, the cinema is actually £60 short of their best scenario. The 20 adults were willing to spend £10 each, so their arbitrary £3 bonus that they didn't actually demand is optimal based on what? Consumers being less evil than companies? Give me a break.

> if the market has vigorous competition then engaging in price discrimination will only drive the customers being discriminated against to your competitors.

It is not discrimination in the political sense, but the dictionary sense: to differentiate. Price discrimination in theory should not drive customers anywhere but rather make them indifferent to their choice of supplier.
"but will make your worst case substantially more painful."

Not necessarily (see, for instance, your memcpy SSE example), but it is bound to make some case more painful.
This has got to be the first article I've read that has incorporated ambient sound. The loop is terrible, but it's still pretty awesome! The coconuts were annoying though.. I hope more articles introduce ambient sound... I'm imagining this being integrated into novels.

Also, this is fantastic. I can totally see this being of interested to the sighted as well; maybe it would see better uptake than glass.

The authors didn't find any smoking gun. None. Zero.

They found some travel sites offering member discounts--no surprise there. They also found sellers were personalizing search rankings--no surprise again. And they found a persistent pricing differential for Home Depot, but were careful to note that it could be a server-side quirk.

No.

Remanence attacks are pointless against non-volatile media. You use them against volatile media in a physical attack in an attempt to sneak under/manipulate the limits of that volatility to cause violations of security assumptions, such as "the keys are in RAM" (true) > "RAM is instantly volatile on shutdown" (not quite true) > "keys are instantly zeroised on shutdown" (not this easily they're not).

Some RAM is much more volatile than conventional bulk SRAM or DRAM (for example, frequently L1/L2 caches on CPUs are impractical to exploit). Properly encrypt bulk data held in high-remenance or non-volatile RAM with a key held in such low-remanance RAM, and your security problem is solved.
Please do audit the Mirage OS as modified in the article and show what you find. I'm interested to see how you can claim that the OS which doesn't even have a file system, has only drivers for virtual hardware and not even code for starting a process isn't more secure than any other big solution. Above all, the code based on the functional language. It's closest to what we have to have a provably secure system.

Thanks for very detailed feedback! There is certainly some room for improvement.

> You don't see a live picture but you can "check in" as you put it by tapping on "record video now" in the app and it will immediately record 5 seconds of video and show it to you AFTER it is done recording.

Technically you don't have to wait until the end of recording, but with short clips it is the case in practice. It takes about that long for the video to propagate along the camera->server->phone chain. You will notice the difference if you try to record for 20-30 seconds.

> I don't see how to save or delete videos. I can imagine wanting to email a video, say for a police report. Or delete old ones if they pile up.

You can delete videos by sliding left over the timeline entries, which will reveal delete button. We should do a better UX job there.

There is also a bug in the current version that affects iPhone6+ which makes this button invisible, that may explain that you don't see it, if you use that phone.

Saving videos: initially we contemplated adding this functionality, but it didn't make the cut for initial release. We will probably add it in the future.

In the meantime, if you really want a copy of the videos, you can create an IFTTT trigger to save videos to Dropbox or google Drive.

Hope that helps!
The thought of starting a company in San Fran makes me cringe a little with prices the way they are...but what you are doing seems very resourceful, kudos to you and good luck.
I don't remember where I saw this, but I believe this has to do with culture. In North America what you described is true, where as in developing countries it is not. The second person would rather just take whatever money is given and run.

If someone can remind me of the name of this game I can find it..
Game theory doesn't come into the optimality of this. Sure you could write out a single sale as a game between producer and consumer, but it's a long way around to get the same numbers out. An iterative game to buy something - what would that be? Extended bartering? I already explained that. I don't understand where expected value comes into it, it's not that kind of analysis.
I'd typically interpret "openly" as implying "out", though.

There are several storage class memories that are nearing commercialization. Intel is betting big on at least one of them. Most technologies in this class are orders of magnitude faster and have orders of magnitude better endurance than flash memory, while being only slightly slower the DRAM, yet non-volatile.

It is plausible that with another layer of in-package cache they could eliminate DRAM altogether, replacing it with ultrafast NVM. Imagine the resume/suspend speed and power savings of a machine whose state is always stored in NVM.
The cadence of this reminds me of William Gibsons Agrippa.
I can clearly see the popular opinion (reddit/hacker news) is that marijuana is harmless. My professional opinion is different, however, and over the course of my career I have seen its affects first hand. Laugh and down vote me if you will, but the negative affects are real and damaging to youth and the research backs me up.

At the same time, when people commit suicide at their workplace, it's often a message. If the suicide rate at the workplace is high enough that you need to install safety nets, it may be viable as an emergency measure, but it's a symptom of what should be considered a complete failure of management. Of course, if you consider your employees as cogs in the machine, it's only expected. Once you squeeze an orange sufficiently, no more juice comes out and you can discard its remains.
They both do! Value != money.

You don't need to subtract a penny to make it so. The value of the product for A must be greater than $13 or A won't buy it. The value of $13 cash must be greater than the value of not selling the product to the consumer or the seller won't sell. Everybody has more value than what they started with!

The only way this can possibly be true for all cases is via per-consumer price discrimination, anything less will always leave someone out.
If anyone ever finds a linux C program that doesn't quite do what they need, my advice is this as I've had great success with it in the past modifying ntfs3g and the like..

Download the source package and open it in NetBeans! For what I needed clicking build JUST WORKED. For my purposes it was a short trip to adding some new arg commands and modifying functionality, then building and packaging it back into a .deb ready to go. I'm not sure if this is still the case, but NetBeans was pretty fantastic for this just 2 years ago.
> You are using the term 'value' in a loaded sense. If you use the proper term "consumer surplus,"

And you think he's making loaded arguments? The value he's talking about is simply the sum of consumer surplus and producer surplus. They're both legitimate; a sale price of $10 allots $9 in gains from trade (or "value") entirely to consumer surplus, and perfect discriminatory pricing allots the same $9 of value to producer surplus, but the value is still produced despite the consumer surplus being $0.

Compare the $14-uniform-price scenario, where the consumer surplus is $2, the producer surplus is $4, and the gains from trade are $6 when they could be $9. That's $3 of lost value, and I don't see why you think that's a biased or controversial way of putting it.

This is the best of new and old-world media. The animations and colors and typography are subtle yet beautiful; I greatly enjoyed the writing. This hits a certain medium between gaudy and bland in terms of taking advantage of new JS / media techniques – where Snowfall [0] was confused, and traditional news seems bland, this somehow hits the spot.

Yes, exactly! I hang out with them when we do stuff together I enjoy; when they don't I decline. eg I find baseball boring, so when invited I say thanks but no thanks.

There's a big button in the upper right hand corner for an audio version, ya dingus. Ever thought that might be useful for people who can't read the website?
SageMathCloud's IDE (which is CodeMirror-based, so similar to Adobe brackets, but online) does this, with a nice slider like in "pirate pad". Just create a file and start editing and it will record diffs at about a 1-second interval, which actively editing. Click on the blue "History" button and you get a slider across past revisions. Jon Lee implemented this functionality last summer. https://cloud.sagemath.com I frequently use this fine history functionality when coding. I'll remember that I had my code in some useful state 15 minutes ago (say in the middle between git commits), and I can easily drag the slider back to that point in time and look at the code. It adds a whole new dimension two coding that dramatically improves things. Unlike with Google docs, the SageMathCloud revision history for a file foo is simply stored in the file .foo.sage-history, with one diff per line (in JSON format). You can delete .foo.sage-history or archive it or whatever.
This is a very, very cool performance benchmark for CSS operations but for the love of god, don't ever even think about using it in production if there is a slightest chance a) someone else would need to maintain your code b) modify the content.

If you actually want to implement 3D graphics in production, please learn it first from a proper source.

This free online course get's you up and running on the basics of 3D graphics with WebGL: https://www.udacity.com/course/cs291

There are fairly decent books on WebGL available as well which also run you through the basics.

To get coherent 3D stuff going you need to actually understand what is going on at a fairly deep level, or you will just ruin everyones day who is a stakeholder in your project. Learn to use Blender at least on a rudimentary level. Learn WebGL. Figure out how to get the 3D content from Blender to your renderer. Then reconsider this.

[Note: I have a few years of professional graphics programming under my belt so I think I know what I am talking about.]

I have an Apple //e on my home work desk. It's running nicely, and it has a spiffy card that allows me to plug a USB flash drive in, boot from an image file on it, and reenter the first real computing world I started with.

Prior to the Apple, I got to flirt with a TRS-80 Model 1 a neighbor owned. Writing a few BASIC statements and actually having the machine respond was intoxicating for me. Loved it, and I knew right there and then I would be doing things with and on computers.

The Apple //e machine represents a whole lot of that early discovery time we all are thinking about. It was open, had a monitor, mini-assembler, reasonable BASIC, and, and, and...

I got bootstrapped onto computing and the magic of assembly language on that machine. And there were others, but that one really was the first. The friends I made, stuff we did, things we learned were like magic. I miss it all.

So, I boot that machine every so often. Really, I always just want to know if it still works. Then, I decide I want to write, play, code, and I do.

When I write, I can do it on that excellent keyboard, with the machine and it's memorable feel. The whole thing takes me back in time, and I do remember. And then I can get it back onto a modern machine with that same USB stick and wonder at such a gap, still being useful.

I was moved by the idea of keeping in touch with the little kid part. Yes. I have a great memory of my childhood, and can tell you many events, times, places, things, people. To be honest, I draw on it an awful lot. Sometimes it's to realize new perspectives for what they are, not as they are framed up, or colored to be. Other times, it's to remember that spark of interest and the drive to learn and explore.

Play. That too.

I love these machines and I love all the people I've come to know related to them. To me, I can understand a lot about somebody when we share a computing experience, be it retro, modern, or maybe something of a hybrid, like embedded.

@japhyr, I don't do it professionally either. Though I have done a few projects, drivers and problem solving. As you are aware, it's a bug that bites deep. Doesn't let go. Have fun. Remember. Your Dad would be happy with you doing just those things.
At root, you labor under the delusion your coworkers have an obligation to entertain you. They have no such obligation -- legal, moral, or practical.

Grow up, entertain yourself; participate in events if you enjoy them, or if not, suggest events you'll enjoy. But don't whine if they don't share your idea of fun and hence decline.

If you live in a reasonably sized city, you can find people into doing damn near whatever floats your boat.

This is really basic social skills.
Here’s How to Increase Conversions Using Color Psychology Methods
Of course, I'm pretty sure there are racists in the south - as well as everywhere else, this is a common mental malady, which, like lice, often manifests itself when proper hygiene is not maintained. However the claim that virtually all white population is so racist as to wish for return of Jim Crow laws feels a bit strong to me. As for voter turnout, it looks like specifically for Mississippi it's not that bad: http://www.governing.com/blogs/by-the-numbers/changes-in-vot...
and actually white voters' numbers are lower than black voters', while overall turnout is one of the highest in the nation - it looks like MS citizens take their voting seriously. Overall, 82% turnout doesn't sound bad at all, and if the hypothetical vote would be on something as outrageous as Jim Crow laws, I would think these numbers would further increase.
15 Landing Page Design Examples and What They Can Teach Us

> these are examples of some of the things you're expected to know as a competent engineer

I find this statement tenuous at best when the example question has absolutely no programming component of any kind and is entirely a little math puzzler about determining the highest floor from which one can safely drop an egg.

It's certainly an interesting problem, and the explanation is presented incredibly well, so I don't fault the site itself. I'm also aware that this is something of a pop culture question for "programming" interviews. However, I don't believe that it is in any sense true that it is necessary to excel at this sort of question in order to be a competent programmer.

This might seem representative of the experience of trying to design a novel algorithm to solve a new problem, but in fact it couldn't be less representative. I've had to write some hairy code in my job a few times, and not once was I under time pressure or expected to have the critical insight within five minutes. Any problem that has any sort of creative or exploratory or "research" aspect to it should not be under time pressure, and ideally it should be mixed in with other work so that you can rest from the problem and come back to it later. The vast majority of candidates who will pass this particular test all the way to the end are ones who just memorized it online.

To be more clear: I'm not saying that they are reversing their "pick a patient" method. I'm saying that I saw how the "pick a patient" powered by the web model was an evolution among international aid / charity models. The "big generic fund" model however clearly is not. I'm not saying it's not convenient, I'm saying I don't see how going back to a model that's been used for decades is useful when such a model is arguably ineffectual at building deeper cross-cultural relationships. Not to mention that neither of these models of international aid or public health build anything sustainable.
I'd say that, while this almost sounds like a reasonable argument to put forward, it isn't probably going to work that way.

Case in point: Gett in NYC. They are running a $10 flat fare anywhere in Manhattan, and promising drivers double pay for three months already. That should undercut incumbents as well as cause drivers to flee, right? Why is Uber and Lyft totally winning NYC while Gett is not even operating at 1/10th the scale?

I think it's got to do with liquidity and reliability. Even if the driver has 10 apps running, the probability that the driver gets the first/most ping from the app with the best client liquidity is extremely high. As long as he's constantly engaged, there is no need for him to open another app. On the flip side, when you're small, your supply runs out quick. If clients opening the app constantly see that, they'll eventually not open your app and go to one with the most supply liquidity. There are strong network advantages in this game. Your paper mostly discounts that.

The sheer amount of time saved won't help you if it goes away, and it could go away in many ways: canceled, poorly maintained until it eventually becomes unreliable, price raised until you can't live with it but can no longer live without it, etc.

It's quite a risk building your business on a single-source product from a vendor whose business wouldn't be significantly different whether that product succeeded or failed.

I hope Google will resolve this by open sourcing Firebase, making it safe to commit to, while providing great paid hosting for it, making it a better choice to pay them for the "sheer amount of time saved", the maintenance, backup, etc., without having to bet the survival of your company on how committed Google ends up being to this minor product over the years to come.
This is not (specifically) for the OS. This is for non-volatile memory that is directly attached to the memory bus. The OS can then directly map NVRAM into the address space of a user-space process; the application could use these instructions to efficiently ensure the crash consistency of its persistent data.
