Hmmmm my math can be wrong but I don't think you are correct:

5120x2880 = 14745600 pixels

14745600pixels x 3 colours, 1 byte each = 44236800 bytes

44236800/1024/1024 = 42.19MB each frame

42.19MB per frame x 60 frames a second = 2531.25MB.

TB2 has a bandwidth of 20Gbps = 2560MB/s

So yeah, theoretically TB2 has enough bandwidth. But it's a very tight fit.

Supposedly 'Albert Einstein' had an IQ of around 160. My father's IQ was tested to be around 200. Yet you wouldn't know who the hell my father was even if I told you his name. It would place him as 1 in 4 billion according to these charts...
http://www.iqcomparisonsite.com/iqtable.aspx

However, Einstein would be 1 in 11,000. If the chart is to be believed, then people with an IQ of 160 or above would be about 655,000 (according to the current world population).

In any case, it doesn't matter so much anymore. My father is nearly broke, sick, and in poor health right now and lives with his parents. He was somewhat successful as a business man, but not overly so. He was well known within his community, and he certainly could do anything he wanted. He was a scuba diver, a pilot, an engineer, he speaks three languages, can play the piano and saxophone, he can program a computer and rebuild engines. Having super intelligent people will not make that much difference in the world, except in the cases where those people lead countries. Until we elect leaders who have such high intelligence, we won't see society change much at all. Intelligence does not equal money, and it doesn't equal power. It just means you can figure out things faster than others. With computers, an average person can solve complex mathematical problems faster than the highest IQ people could 100 years ago. IQ is far less relevant in today's world.

In any case, even if these high IQ people were elected, what happens when one of them has a stroke and all of a sudden their IQ is only half what it was (500)? Should we have a vote of no confidence and shun them from society? This just ends up as eugenics all over again.

Not a bad price until you see it costs $300 to go from 4GB RAM to 16GB RAM.

Do these have user-upgradeable RAM? I can buy RAM a lot cheaper than that.
I have been running Yosemite since its first release. I don't think the link on apple's site will work for you if you are not :

- Registered developer for OS X Beta
- OR initial fist million beta testers

I get the same error, though I get regular updates about Yosemite from App store since I registered as the first million beta tester.

Hope that helps. Let me know if you have more questions.
I have it set to the max too. It still stutters here and there, but definitely not as much as Mavericks did.
The Mac mini when first introduced was $499.
If they had a 32G entry option less people would buy the 64G one.
Typically 30hz ones, so not suitable for general computer use. 60hz still tend to be fairly expensive.
Yes, via DisplayPort 1.2.
If you check the pricing, what they've done is lower prices of the expansions $100 over what they were before, but somehow left the base models at 16 GB. Yesterday $600 got you 32GB and an A7 processor, while today gets you 64GB and an A8x.

So the better question is: how is Apple getting away with selling a 16GB option for $500? It's not really that much space, especially when you take the OS and the space necessary to download updates into account.

I can totally agree with you, accept that I would say that for the future to be brighter, to be more filled with highly qualified talent, you need to increase the pool of potentials. That means more education sources and building interest and awareness around it. That's what bootcamps are doing, whether its for that purpose or otherwise.

We're actually far MORE interested in the long long term solution, which is teaching code as part of standard education. Its inclusion in schools. We're actually joining efforts with teachers, administrations and government in both the US and the UK (closer to home for us) in the effort to make this possible.

Linux has always supported UDP reassembly. Quoting a manpage:
"By default, Linux UDP does path MTU (Maximum Transmission Unit) discovery. This means the kernel will keep track of the MTU to a specific target IP address and return EMSGSIZE when a UDP packet write exceeds it. When this happens, the application should decrease the packet size. Path MTU discovery can be also turned off using the IP_MTU_DISCOVER socket option or the /proc/sys/net/ipv4/ip_no_pmtu_disc file; see ip(7) for details. When turned off, UDP will fragment outgoing UDP packets that exceed the interface MTU. However, disabling it is not recommended for performance and reliability reasons."

And they ain't kidding, because there are plenty of layer 3 devices out there who play fast and loose with fragments of UDP packets; it used to be you could assume they'd drop anything that doesn't have a header, so by default UDP on linux doesn't encourage it.

It could be that distributions have been bundling sysctl.conf files with ip_no_pmtu_disc set to true, being that most modern layer 3 devices no longer mistreat UDP so badly; this may be what you're experiencing in the last year.
That's interesting, could you please share the data ?

Akshay, it looks like you're the person who wrote this and posted it. Thank you for the contribution. It deserves to make the front page.

This is insanely important and may be the best HN link all week. Any engineer who routinely feels frustrated when working with other people should pay attention to this.

I've done engineering and sales, which are very different skillsets. More importantly, I have been mentored by other people who are world class at these respective skills, and have been very lucky to have the opportunity to learn from them.

Even though not everyone should learn to code, it is valuable to be able to put on the other person's hat.

Non-engineers need to respect that engineers deal with situations that don't happen in everyday life. An engineer is frequently presented with situations that boil down to "it does work" or "it does not work". There is no gray area, and typically the computer is not very polite in the way that it tells you that you're wrong -- errors rarely say "Hey, I hope you aren't upset about this, but something's not working right. Want to talk it through and find a solution?" Instead, we deal with messages that have the emotional sensitivity of "screw you!", or if we are lucky, "screw you! #32"

Being in this mindset all the time will condition you to thinking in a certain way, and that's what is required to program. People, on the other hand, don't work like this, and if you can see the difference and act on it, you will benefit from it.

> Of all the drivers you've seen on the road, do you rate yourself above average compared to them?

Using the second concept of "average," yes I do. I have seen lots of car accidents, and lots of people pulled over by police (presumably for speeding or reckless driving). I have never experienced either, other than being pulled over once for a missing tail light (humorously, literally hours after I had purchased that vehicle). So I do consider myself a better than average driver.

But this idea of "better than average driver" just isn't very useful. Because presumably the majority of drivers have not been in an accident, while the average number of accidents per driver is obviously greater than zero. Thus most people are better than average drivers, in the same sense that most people have more fingers than average.
Well, I've never used OProfile myself, so please take this answer with a grain of salt, but from a quick perusal of their website, and as the project's name seems to suggest, OProfile is a sampling profiler, which usually means it will collect data from counters at given intervals of time, producing a number of statistics over time. This generally implies a somewhat significant overhead, and consequent performance drop.

LTTng, on the other hand, is a tracer, which means it collects events from the kernel (using the built-in tracepoint facilities) as they happen. It's also possible to trace userspace apps (with lttng-ust), or define your own tracepoints. This has the benefit of being much more detailed, and also has a much smaller overhead.

You might be interested in reading the "What is Tracing?" section of the lttng docs [0], which does a far better job at explaining this than I do.

Yeah you can convert between units. But as soon as I saw imperial units I just closed the site. If you want to publish something on the Internet you have to take into account that users will be way too lazy to convert. And I don't want to support imperial measurements in any way or form so I would rather not use a site or a service that uses them.

Wow. I've been waiting for a screen like that for a decade now. My first Mac purchase (retina display Macbook) was made only on the basis of the screen, and I don't regret it at all.

Really? I feel like most people I know who were developers before the bust are either millionaires or still rocking. A few moves on when the bubble blew out, I even lived in an apartment in SF of a failed 2 man company during that time period; they both went to back to being finance guys. But that was the catalyst of the industry we're now all talking about, and its grown more and faster than many other.

It also took a lot of crappy people to produce the few genuine talents that took the industry by storm. The industry is growing faster than talent because its not standardized or accessible enough for all potential to be found. The problem is greater than a discussion of the validity of bootcamps, and though business driven I would argue bootcamps are a step towards understanding the true needs on a global scale.
The fastest new processors, whiz bang features, and the boat anchor of 16GB starting memory. At this rate we'll still have new devices in 2020 that start with 16GB.

Yes I know it's a sale tactic to get you to "upgrade" to 64GB and recoup some nice profit margin, but 16 is too low for a lot of people, and 64 is a waste.

Android suffers this a lot. Brand new high end model $650 phone, 8GB of usable space.

You also have to define "better". Here we are only talking about super intelligence. But what about creativity in music, film, writing, etc. Those things enrich our lives. Who is going to make the films and animes that I love?

What if the person does not fit your definition of a super intelligent person with a high IQ but instead is a genius in music. Also, how do we know that by focusing only on super intelligent people we won't be killing off the other traits that make life worthwhile, the arts, music, film. There are multiple perspectives that make a person a genius, high IQ is just one of them among many.

As somebody else mentioned, just like breeding dogs, you may be able to select for one trait at the expense of the others.

Frankly high IQ is overrated. It is probably biased anyway. i.e. Children that grow up in high income families have better IQ results than children living in poverty. It could simply mean that the differentiator is good education at an early age.

In theory, if I put $N into an equity, then someone else will get $N out, because efficient market and all that. That frees the same $N up for that other person to consume/invest.

I'm slightly bummed that I can't get SSD on their starting model, and have to force myself to a fusion drive if I want to do better than hard drive.
They did the same thing with the new iPhones.

I'm no Apple insider, but my hunch is that 32GB is right in the sweet spot of what most people probably realistically expect to use. So, basically, they could easily give you the 32GB in the baseline model, but they know that if they do that, they'll be leaving a lot of money on the table because there isn't a stark difference for a large percentage of users between 32GB of storage and 64GB. 16GB on the other hand is a different matter.

The fact that so many people are complaining about this is probably a sign that, if that is indeed the reasoning behind the lack of 32GB model, it was a smart choice from a profit perspective.
its been well overdue for an upgrade, if you had asked on forums everyone would have suggested you wait.

If the noble concepts supposedly behind democracy had any traction with governments, they would have led us to a direct democracy, not a representative one. Instead, we get a half-assed attempt at letting free-people to rule themselves.

Forget money as some sort of concept that breaks democracy by allowing people to game the system. The bigger problem you have to worry about is the smooth-talkers, the influential leaders and all their legions of followers. Their single influential vote, counts a whole lot more than yours, or ours, and that single vote means no equality.
That would forego any kind of comparative advantage each person has.

"Just as there is only one best charity, there is only one best way to donate to that charity. Whether you volunteer versus donate money versus raise awareness is your own choice, but that choice has consequences. If a high-powered lawyer who makes $1,000 an hour chooses to take an hour off to help clean up litter on the beach, he's wasted the opportunity to work overtime that day, make $1,000, donate to a charity that will hire a hundred poor people for $10/hour to clean up litter, and end up with a hundred times more litter removed."

In my experience, colors just look better on glossy displays. Since glossy screens are ubiquitous on phones and tablets, I would figure most people are used to the reflection issue by now. Personally, I don't notice reflections unless the screen is off, but it is obviously going to depend on your room.

The average person in prison would be worse than the average person not in prison, at least if we assume a naive model whereby most violent criminals are caught and imprisoned for some extended period of time. But it could also be true that most people in prison are not worse than the average person not in prison.

Of course, this is also assuming away the vague and subjective task of determining "how bad" a person is.

OS X 10.10 Yosemite: The Ars Technica Review
I sincerely hope you see the contradiction in your comment.
> They don't earn anything, but you can't lump them in with a poor fast food worker can you?

There's a meaningful economic class distinction to be made, probably, between a tenured faculty member at a university and a fast food worker, even if somehow their income ends up similar (the former having greater economic security than the latter, likely).

But I think the distinction you are making is more about subculture than economic class. This particular axis of subculture may sometimes be referred to as "class" (particularly by the people on the "higher" end of it) -- though its probably less common in the US to do so than it would be in Britain -- but its really a largely orthogonal concept to economic class distinctions. Not completely independent though, as -- as many axes of subcultural variations do -- it can have important relations to social networking opportunities that play a role in economic opportunities.

This is clearly even more visible, and arguably more substantive, in the United Kingdom -- where, in addition to the kind of examples you cite, there are, for instance, still hereditary peers in the House of Lords, and, heck, still a House of Lords -- than the United States.
