cherry_su··on The cognitive differences between men and women
Some variation could be explained by the existence of a second X chromosome. This redundancy hides variation that could otherwise be exposed by a recessive gene on a male's sole X chromosome, without the chance of a dominant gene on the second X chromosome to mask it.
cherry_su··on On the road with the 13-inch MacBook Pro
For what it's worth, the 13-inch MacBook Pro with 2 Thunderbolt 3 ports (this one) gets a hair over 16 hours of battery life in Ars' Wifi Browsing Test. Unfortunately, this benchmark did not contain a measurement for the 13" MacBook Air, its spiritual predecessor. The old 13" Pro got 14 hours.

cherry_su··on Tech workers think Silicon Valley and startups are losing their luster
Out of curiosity, what did you find unbearable about the culture?
cherry_su··on Social Mobility May Suffer as Income Fails to Keep Pace with Housing Costs
Figure 1's concentration of orange and yellow areas looks moderately correlated with the Bible Belt (https://en.wikipedia.org/wiki/Bible_Belt), in which socially conservative evangelical Protestantism plays a strong role in society and politics, and Christian church attendance across the denominations is generally higher than the nation's average. It would be interesting to explore this relationship further.
cherry_su··on I Drove Chevrolet's Bolt
Depends -- If a model has a bunch of body styles and only the most popular is tested, then the manufacturer can skimp on the designs or constructions of the versions that don't get tested.

Ford did this with the 2015 Ford F-150: http://blog.caranddriver.com/iihs-2015-ford-f-150-crash-test...

"""[…] the SuperCrew’s body cage remained “largely intact” with a “low risk of injuries,” the group said. The smaller F-150 SuperCab pickup (pictured at top) scored “marginal” due to “significant intrusion” of the passenger cabin, as the dashboard and steering wheel came “dangerously close” to the dummy’s chest. Since the A-pillars buckled and other body components “seriously compromised the driver’s survival space,” the IIHS rated this F-150’s structure as “poor,” which is below “marginal” and the group’s worst rating."""

cherry_su··on A visit with Apple’s chief chipmaker
I can imagine that part of his team's excellence and efficiency is due to not focusing on differences not directly relevant to technical problems:

Although Israel grapples with Jewish-Arab tensions all the time, none of it mattered in Srouji’s world. Cohn, who remains friends with him, says their different backgrounds never came up. “Technical people treat technical people based on personality and technical ability,” he says. “You don’t think about it. You just work together. The rest goes away.”

cherry_su··on Dell XPS 15 review: A bigger version of the best PC laptop
The keyboard would become more off centered. Without the extra keys, the F and J keys are already slightly off centered because of the quote key.

edit: What if this column were on the left of the keyboard to offset the quote key? Then the keyboard would be symmetric with respect to the F and J keys.

cherry_su··on The Tenacity of Tech Recruiters
Basically the Silicon Valley/Software Engineering flavor of "Don't Even Reply" (http://dontevenreply.com/), which I highly enjoyed reading.
cherry_su··on Children of the Yuan Percent: Everyone Hates China's Rich Kids
Not quite a book, but you might find the materials for this MIT course on Game Theory and Social Behavior insightful: http://ocw.mit.edu/courses/economics/14-11-insights-from-gam...

"We will apply insights from game theory to explain human social behavior, focusing on novel applications which have heretofore been the realm of psychologists and philosophers—for example, why people speak indirectly, in what sense beauty is socially constructed, and where our moral intuitions come from—and eschewing traditional economic applications such as industrial organization or auctions."

I learned about signalling theory in this course, among other insights into why society acts the way it does.

cherry_su··on Porsche 911: 52 years of staying true to its roots
pg has mentioned the 911 (at least the vintage versions) in his essays about good design, which usually is timeless. While the upcoming 2017 revision will be disappointing to me due to ditching the naturally aspirated engines in all but the track (GT3) cars, here's to another 50 years of 911.

cherry_su··on Tesla’s Model S Gets “Ludicrous” Mode, Will Do 0-60 in 2.8 Seconds
Let's take Nurburgring-Nordschleife, since that's generally accepted as The Proving Grounds. For these three cars in question:

cherry_su··on How a car works (2012)
To add to your last statement, it seems like cars are engineered for the length of a typical lease. Afterwards, nondeterministic electric gremlins start showing themselves.
cherry_su··on Tesla’s Model S Gets “Ludicrous” Mode, Will Do 0-60 in 2.8 Seconds
It [Tesla Model S CoG = 17.5-18"]'s competitive with supercars, i.e. that of the Ford GT [1], and better than the Porsche Boxster [2], which is not a supercar.

cherry_su··on Show HN: AutoAPI Vehicle Web Crawler – Searches the Web to Find the Best Deals
It seems working now. (Mon July 13, 10:43 Pacific).

One thing I noticed is that the range is capped to 100 miles. An unlimited range would be incredibly useful for searching for used exotics, i.e. Ferraris, which is a valid input parameter :-). Since supply (both overall and for a particular configuration) is so limited, it makes sense to buyers to fly to see the car or to buy blind and ship the car to them.

cherry_su··on What happens when you stop relying on resumes
> unwilling to compromise on things that don't seem worth fighting for

It's quite possible the interviewee thinks the item is worth fighting, but you don't because of different principles/axioms. Are you looking for a justification in this case?

Note that the curfew (seemingly) does not apply to full-time employees, so a fresh grad could be working the night shift.
cherry_su··on How it feels to join an all-Haskell startup
Of the three, I'd contend <$> is the most reasonable to do since it's very similar to $ (which is commonly used), but applied to a boxed argument (Functor).

Yes. This procedure was used last year.

cherry_su··on Why Ferrari engineers don't like turbos
Absolutely, except launch control software is the one dumping the clutch for you in the Ferrari, so the 1 second of spooling is irrelevant for obtaining the 0-60 time.

cherry_su··on The 2014 Mac Mini reviewed
Probably for ease of design and manufacturing. Apple raids the corporate parts bin: the lowest SKU, like the base iMac, is a MacBook Air in a box. The mid and high tier SKUs are repackaged 13" MacBook Pros.
cherry_su··on Apple Mac Mini
Just kidding. Even if Apple doesn't say "onboard memory," that doesn't mean the computer does not have onboard memory.

cherry_su··on Apple Mac Mini
There are no 2.5" 3TB drives, and even if one existed, it would be 12.5mm (or more), which may be too thick for Mac mini (standard 2.5" drive thickness is 9.5mm).
cherry_su··on OS X 10.10 Yosemite: The Ars Technica Review
It's still there, but now you hold shift+vol up/down to hear the feedback. This is in contrast to earlier OS X versions, where holding down shift will mute the audio feedback.
cherry_su··on Apple Mac Mini
Yes. Tech specs do not say "onboard memory." http://www.apple.com/mac-mini/specs/
cherry_su··on Apple Expected to Consume 25% of All DRAM in 2015
Maybe the Mac and iPod businesses more than makes up for the difference? I don't know how Samsung's other DRAM-consuming businesses compare.
