> How does the retina screen scaled 1920x1080 compare to a laptop with native 1920x1080?

IMO it looks much better. Only rasterized objects are scaled. Fonts and native components still render at full DPI.

> I realize Apple doesn't provide a native 1920x1080, but it's not hard to find in non-Apple 15" laptops, at an easy $1,000 cost savings for higher-performance components (but less thin-and-light).

Good luck finding one with equal or better build quality that will run a POSIX OS flawlessly (no driver issues, no hacking configs or recompiling, etc) and costs $1000 less. I looked at a lot of other hardware before buying my 15" rMBP and couldn't find anything that measured up.

> Bill Clinton presided over the largest economic expansion since World War II; he was a lawyer just like Obama, would you have hired him to run your startup?

I've seen this used over and over again. The economic expansion you refer to was fueled by what was happening with the Internet. Clinton had nothing to do with that. He just happened to be there while it was happening. Some folks choose to ignore the facts and attribute the economic expansion to his administration.

The economic expansion that took place during his administration was the consequence of series of events spanning a couple of decades before he even ran for office.

If we are going to play that game you might as well attribute the 9/11 attacks in NYC to Clinton. In other words, if we are going to credit a president with everything that happens during their administration you can't pick the good and ignore the bad. He had a chance to get Bin Laden and did not. The plans and training of the dozens of terrorists who conducted the attack happened under his watch, right here, in our soil. In eight years he failed to re-shape our security services in order to make them more effective at dealing with terrorism on our soil. Was he responsible? Who, then? Don't say Bush. The attack happened during his watch, but all the preparation and training --right under our noses-- happened under Clinton's watch.

My point is that it is important to get past a partisan defend-your-team-no-matter-what attitude and make an effort to understand the underlying facts. Of course Clinton was not responsible for the 9/11 attacks, just like he can't take credit for the economic expansion. Events like these are often the result of decades of interrelated issues that, ultimately, trigger them.

It's like the infamous "overnight success" entrepreneur. From the perspective of his or her neighbors they made it big overnight. The reality, though, is often very, very different involving hard work, insight, sacrifice, failures and often years of investment and dedication. Nobody sees that. Nobody tries to understand that. All people see is a new car in the driveway. They choose not to think and reach inaccurate conclusions.

To get back to 9/11 briefly, it was probably the result of maybe fifty years of making questionable foreign relations and internal decisions. Possibly even longer than that. Hard to say. If you want to blame anyone I think we need to blame the process, not the people involved.
It is a huge number. Of course the fun part is that after precisely calculating that probability and proving that we don't have anything to worry about, the next commit we make could collide... and it will be the only git collision within the history of human race.

Probabilities are fun, because anything non-zero is non-zero ;) (I don't expect to ever witness a git hash collision of course)

Agreed, one can't say that all PIs work the same, it isn't true.
Also, some do have the best of intentions, but don't have the skills to facilitate their student's career.

In a sense, each lab is a small business, and I think this is exactly what needs to be taught to a new professor. It is a real shame that this isn't taught. People management, money management, and resource management are skills that some people, regardless of how brilliant they are, don't have.
As it would in any business, these attributes ultimately lead to a lab that is run poorly. The really bad thing is that these labs continue to operate, which is a huge waste...especially when talking about federally funded labs.

With Almost 1M Users, Followgram Challenged by Instagram Web Profiles
...One thing that Followgram has done well is attract a number of major brands to use its service, including National Geographic, Armani and Dolce and Gabbana. Lalli said that he considers the company’s popularity among brands like Nike to be an indication that Followgram is moving in the right direction. However, Instagram has already touted Nike as one of its first new profile account users. According to Lalli, Followgram has been bootstrapped to date, and the startup plans to earn revenue through two business models, a paid pro account and an online store that will let users order items including prints, frames, magnets and postcards...

I'm not a .NET developer, but Rx was still one of the more interesting things I learned this year.
You should look more deeply into how these things work. Let's take the DAX Futures for example (which he was trading). All numbers are in EUR.

One "tick" (minimal movement) is worth 12.5 EUR. At volume you pay 0.5 EUR, IIRC, but let's assume you pay 1 EUR in fees, everything included.

If you bought and sold at the same price, you lost 1 EUR/trade. This is the cost of business.

If you bought, and sold after a favorable 1 tick movement, (e.g. bought at 4013.0 and sold at 4013.5), you're 10.5 EUR richer - 12.5 on the difference, minus 1 for each trade (one buy, one sell).

If you bought and sold after an unfavorable one tick movement (e.g. bought at 4013.5 and sold at 4013.0), you're 14.5 EUR poorer - 12.5 on the difference, and 1 for each trade (one buy one sell).

OP averaged $2/trade over 200,000 trades; that means he had 2/3 right calls, and 1/3 wrong calls or so if he only traded dax and only had 1 tick moves.

He was very smart, but you're looking at it wrong - the fees are the cost of doing business, much like salaries are the cost of producing software. In finance, you rarely care about revenue or "notional" (which can easily run into the trillions per year for a small trader - for ~1 eur, you get 75,000 eur in notional value on the dax).

You just roll the fees up-front into your choices when thinking about it, and it all makes much more sense.

(Not trying to take away from OPs very commendable achievement - just trying to give the common perspective on how to view this)
This may be a bit mean but I'm picturing you looking a bit like Marty Feldman. Sorry. I have sympathy though: I have keratoconus in both eyes as well as severe astimgatism. I find the 1680x1050 antiglare screen on my 15" MBP just about perfect. I have a 27" Thunderbolt panel too, which looks great but for some reason I find it hard to focus on for long periods. My eyes kind of 'slip off.'

Tip: enable "Use scroll wheel with modifier keys to zoom" in Universal Access->Zoom->Options. Ctrl+scroll (ie two finger vertical swipe, or mouse wheel) will now zoom the window around your pointer. It's a massive help for tired eyes; you can just enlarge the stuff you're working on. I don't have to go in far for it to make a huge difference. (I found it somewhat humbling to have a legitimate need for an accessibility feature.)

If they had stopped accounting for race, the number of black students would have dropped greatly.

I agree. I run my 15" at 1920x1200. Rasterized graphics can be a little fuzzy if you look closely but it's hardly noticeable. If you spend most of your time doing graphics work then yes, you'll probably have issues. Photoshop CS5.1 is really bad. Other than that I like it much better than the previous 1680x1050 screen.
On the last point, my experience is in CS, but it's worked similarly in other departments where I know PhD students and/or profs. When a professor at the places I've been hires a research assistant on grant money, the grant account is charged stipend + tuition (plus overhead, but that's usually already been taken out up front). It might be a reduced tuition, e.g. at state universities it's common to give an out-of-state tuition waiver so the grant is only charged the in-state graduate tuition rate, even for out-of-state students. But that's often still in the $10-20k range.

If the student isn't grant-funded, then yes, the prof isn't expected to pay them anything: the department will cover their tuition, and they'll work as a TA to earn their stipend. But at R1 universities it's nowadays expected that profs will fund at least a substantial proportion of their PhD students each year on RAships paid out of grant money.

The difference is not always obvious from the student perspective, though: when departments say they guarantee funding for 3 years, they just mean that somehow the student will be funded each year, not that the department will pick up the funding each year. The goal is to get the profs to pay for as much as possible out of grants, with departmental internal funding as a backstop.
This reminds me of the need for robust P2P tech in the name resolution layer.
I agree and want to add this: If you take a look at your requirements and how you use the screen, and compare them to my own, you can see how incredibly versatile a screen like this is. I really hope both the hardware and software that makes it happen becomes widespread.

Theres a level of flexibility and choice I didn't realise I wanted until I got used to quickly switching between scaled the various default osx scaling and full native res at the drop of a hat, to suit whatever I'm doing.

How about efficiency? People call the liquidity providing aspects of HFT 'bullshit', but computers have vastly reduced the manpower necessary to manage a market.

Each futures pit used to have hundreds of traders, who required several assistants/support and commanded a huge salary. Many firms needed multiple traders in a pit, just to be able to make sure they could provide liquidity to all possible market participants. Today, a couple strategists with a small team of programmers can cover dozens of futures markets at once.

The same principle holds across bond, FX, equity and options markets alike. HFT has supplanted a terribly inefficient market with a better one. Is it perfect or even good? Probably not, but it's magnitudes better than the traditional method.

What I have opined is that the manner in which the current focus Retina has affected Apple's branding marks a shift in the structure of their advertizing.

It has gone from emphasizing the system (e.g. "magical iPad" or "I'm a Mac") to emphasizing the specs of components, i.e. the Retina advertising logically equivalent to focusing on more RAM or a bigger Hard Drive. Fundamentally it's just numbers.

There's no direct engagement of the consumer's imagination. "Ten hours of battery" allows a person to picture themselves untethered in a Istanbul coffee shop. "More pixels" doesn't.

I've been out of school since May 2010 and I have been employed for the majority of that time since then.

The problem that I noted in the post with stockpiling cash is that I can quantify exactly how much I am losing by saving up rather than spending the money on loans. Furthermore, I made the decision to contribute to retirement first because 8% (average stock market annual returns) in the long run (30+ years) is better than 7.4% (fixed loan-rate returns) in 7 years. So, I have this battle between long term net worth optimization and my yearning to start a business.

I haven't thought about contracting. How does one break into being a contractor? I've searched before and it amounted to competing with others on elance.com or doing work for free until someone can recommend your work to get paid for it.

I see questions here in the thread about how university selection currently works in the United States. There is quite an exhaustive thread on that subject, "'Race' in College Admission FAQ & Discussion," on the College Confidential discussion site,

http://talk.collegeconfidential.com/college-admissions/13664...

and the first few FAQ posts in that thread link out to much official information about current United States policies on the subject, current college practice, and the controlling Supreme Court cases. There is, of course, a case currently before the Supreme Court that may result in a change in the controlling law, and commentary about the pending case is also linked to from that thread. The issue of admission of Jews to United States universities is also discussed there.
> interacts in complicated ways in a portfolio, which I'm sure you know.

Yes. And assumptions about this are bound to break at the most inopportune moment, see e.g. AIG, which I already referred to. Read about the "copula model" disaster, as your statement indicates you are unaware of its details. https://en.wikipedia.org/wiki/David_X._Li#CDOs_and_Gaussian_...

> 1 long, and 1 short trade will cancel each other out and create a riskless portfolio (with 0 return)

This is true if and only if the long and short are in the same exchange, AND exchange rules allow netting long vs. short deterministically. Otherwise, you have counterparty risk. E.g., you can be long SPY and short SP contract (in equal underlying), which would theoretically mean your only exposure is interest rate changes (and sometimes not even that!)

However, since this is in different exchanges, it might happen that during a flash crash, your SPY position will be liquidated for insufficient margin at a low price, but then the price bounces back, and you've lost money on a perfectly hedged position.

OP's model (limiting exposure and assuming the worst, if I understand correctly) is not statistically efficient use of margin, but it's way better at actually managing risk than any statistical model.
