Make your own chunks, and the algorithm easily becomes embarrassingly parallel. Give each of the 100 cores 1 GB, let them run independently, and don't sweat the few bits of compression efficiency you might lose. If Amdahl's Law comes into play, it's because you're constrained by memory or some other I/O system rather than the CPU core.

Decompression may not be embarrassingly parallellizable for an existing algorithm, if it relies on state that persists through every bit in the data set. But a codec algorithm can be designed to be embarrassingly parallel for both legs.
Pretentious is an understatement.

>San Jose was celebrating their first 4 miles of light rail (in just 10 years from the start of the project!)

> Actual work days might be 90 for a mile of track, but time actually passed is like a year

So currently, San Jose can build 0.25 mi/year. Optimistically, with no lawsuits, their actual work days could increase to say, 225 days/year, which is 2.5x faster. So we're up to say, 0.66 mi/year, which still sounds way too low. What are the other bottlenecks?

Look over a list of who the victims of the Titanic disaster were -- comparable in that it was the luxury travel alternative of its day. Jay Jacob Astor, Benjamin Guggenheim, Ida Straus (founder of Macy's), just to name a very few. The societal impact of the Titanic's loss was ... titanic.

You wouldn't even need an explosive to foil the tube. Simply something to perturb the system slightly would disrupt it in a bad way. Even if only a single small transport were in the vicinity, any others in the tube would also be doomed (granted, at 1 hour/trip, headways would likely limit this to a very few instances).

Trains are very robust. Conventional high-speed rail is a bit riskier, but even accidents such as on the German Eschede rail disaster (at 200kph) saw over 60% of the passengers survive: https://en.wikipedia.org/wiki/Eschede_train_disaster

"... Of course, back then the sense of mission was boosted by the fact that Microsoft stock increased 90-fold in the 1990s, creating a host of stock option millionaires. Those days are long over, and Microsoft shares are still well below their 1999 peak.

The idea that the company can embody a start-up spirit at this stage of its development might also be a stretch. A recent book published anonymously by two former Microsoft employees, called ‘Stack Rank This!', portrays a company beset by abusive managers and dysfunctional teams where the appraisal process - the notorious stack rank system - actually works against the company's progress."

Fair enough. I imagine there's a trade-off between the quality of the tunnel materials and the number of pumps needed along the way, assuming an imperfect vacuum is good enough.

I'd be worried about flexibility too. Skyscrapers do pretty well in high winds and earthquakes, so I'm not completely convinced that a similar effect isn't possible with an underwater tube. Any bending would have to be extremely gradual, though, if there's any hope of shooting something through it at high speeds. I agree that glass isn't going to cut it.

The research is using SAT score as a proxy for general intelligence.

Despite a number of statements to the contrary in the various comments here, taking SAT scores as an informative correlate (proxy) of what psychologists call "general intelligence" is a procedure often found in the professional literature of psychology, with the warrant of studies specifically on that issue. Note that it is standard usage among psychologists to treat "general intelligence" as a term that basically equates with "scoring well on IQ tests and good proxies of IQ tests," which is why the submitted article has a point.

http://www.iapsych.com/iqmr/koening2008.pdf

"Frey and Detterman (2004) showed that the SAT was correlated with measures of general intelligence .82 (.87 when corrected for nonlinearity)"

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3144549/

"Indeed, research suggests that SAT scores load highly on the first principal factor of a factor analysis of cognitive measures; a finding that strongly suggests that the SAT is g loaded (Frey & Detterman, 2004)."

http://www.nytimes.com/roomfordebate/2011/12/04/why-should-s...

"Furthermore, the SAT is largely a measure of general intelligence. Scores on the SAT correlate very highly with scores on standardized tests of intelligence, and like IQ scores, are stable across time and not easily increased through training, coaching or practice."

http://faculty.psy.ohio-state.edu/peters/lab/pubs/publicatio...

"Numeracy’s effects can be examined when controlling for other proxies of general intelligence (e.g., SAT scores; Stanovich & West, 2008)."

As I have heard the issue discussed in the local "journal club" I participate in with professors and graduate students of psychology who focus on human behavioral genetics (including the genetics of IQ), one thing that makes the SAT a very good proxy of general intelligence is that its item content is disclosed (in released previous tests that can be used as practice tests), so that almost the only difference between one test-taker and another in performance on the SAT is generally and consistently getting all of the various items correct, which certainly takes cognitive strengths.

I still think Stanovich's point is interesting that there are very strong correlations with IQ scores and SAT scores with some of what everyone regards as "smart" behavior (and which psychologists by convention call "general intelligence") while there are still other kinds of tests that plainly have indisputable right answers that high-IQ people are able to muff.

(Disclosure: I enjoy this kind of research discussion partly because I am acquainted with one large group of high-IQ young people

http://cty.jhu.edu/set/

and am interested in how such young people develop over the course of life.)
I've said this before and I'll say it again. One of the villains in this piece is Apple. Many of the people reading this comment are talented engineers. What Apple needs to survive, more than anything, are talented engineers. So don't work at Apple. Don't work for companies that compromise ethics in this way.

There's a reason Microsoft has been failing to compete for a while. It's because its practices got so evil that if you got offered a job there, your friends would make ha-ha-only-serious jokes about you going to work for Darth Vader. And so the best engineers, the one with options, went looking elsewhere. We need a culture like this now around Oracle, around Apple.
Apple is probably right here for most of their customers.

It is increasingly obvious that ubiquitous broadband network connections permit the offloading of computation and storage to the cloud.

Why sell the customer a server-style box, when Apple can rent the same compute capability from their cloud?

Furthermore, Mac Pro profits are rapidly decreasing as a share of total Apple profits, and Apple is ruthlessly focused on a few consumer-oriented product themes.

I'm surprised at everyone quoting the same line and no one crying, "Foul!":

"the new iPad starts at $500. Premium Windows 8 tablets will likely run between $800 and $900."

Well, what's the "Premium iPad" go for? What do Windows 8 tablets start at? It's like saying "The entry level Mercedes goes for $50,000. The premium Porsche will likely run between $100,000 and $140,000." In that example, both can cost the same - it's all in the options/model chosen.

I don't know what the actual prices of the Windows 8 tablets will be but I'm assuming Microsoft hasn't made their entry-level product 40% more expensive than the iPad.

If you can't make it work, you should not be able to tax the people who did make it happen. And you definitely should not be able to prevent certain technological developments using the legal system just to protect your existing business.

What's so special about this application that a concerted week of coding could not duplicate? It seems like a list of icons, and when you touch an icon a word is spoken. There is a facility to add new icons. The application also seems to permanently fix the location of each "learned" icon, so that as the child grows their vocabulary consists of an expanding set of "muscle memory" movements. There is also a facility to flag attempts to add duplicate icons. [1]

The SAT was created in 1928 with the intentions of measuring a student's aptitude. meaning that the test measured an innate ability, rather than knowledge acquired through schooling. Today, the test administered by the College Board is still called SAT, but the name is just an acronym, with the letters no longer standing for anything. According to the College Board, the SAT now does not measure any innate ability.

the SAT and ACT simply provides a common yardstick for comparing grades at different high schools. Educators use them as way to judge an A at this school or this teacher versus an A at this school or this teacher. Nothing more. At best the SAT is said to predict freshman year grades in college (somewhat).
> Microsoft is afraid to cross the chasm. It must become a hardware manufacturer to compete with iPad.

Well, Microsoft as a company already crossed that chasm with the XBOX (and Zune, if that matters). But yes, for the Windows section of Microsoft, that is a huge step to make.
You mean we wont be printing hardware in 10 years?
That's the trouble, though - will Windows RT really offer file system access? I haven't seen guarantees that it will.
After years I still fail to understand how Microsoft thinks an OS is worth the prices it charges. I see two possibilities:

1. The OS isn't worth this, in which case it's either extortion (if their partners feel they have no choice) or cluelessness (if their partners end up walking away).

2. The OS is worth this, in which case they've over-engineered: they made their particular OS do way more than it's supposed to and are trying to recoup the cost of developing so damned much.

Fundamentally, an OS needs to boot a device and provide resource management. In order to be compelling to developers it needs to include good libraries that make common tasks easy and tricky tasks efficient. ARM tablets don't even need Windows' backward-compatibility, so there should be a heck of a lot they can just drop out of it! It is hard to imagine this OS being a beast; apparently it is.

Technical points aside however, Microsoft is also the underdog, and a rich one. If anybody should be eating the true costs of an OS and charging partners $6 a head to boost adoption (whether or not it's worth $85), it's Microsoft.
You could raise the same objections to the original 'machines'/'widgets' formulation. (There are always economies or diseconomies of scale.)

Typically such questions imply the unstated assumption, "answer to the same level of precision/abstraction as the question itself, and assume you have all the info needed to give an answer". With that assumption both questions should be answerable.

Compression tends to be pretty parallelizable, if by nothing else than choosing to break the input into separate chunks. You might lose a little bit of efficiency in output size – more restarts, each compressor has less global information – but those don't mean slowdowns (and in a few contrived situations might even mean speedups at the cost of size). See for example 'pigz' and 'pbzip2'.

If I were asking this question, I'd accept the 'rough, assuming perfect parallelization' answer as correct-enough in the spirit and level-of-precision implied by the question. If the answerer brought up the difficulties in assuming perfect parallelizability or specific to compression algorithms or choice of inputs, that'd be worth some extra credit, and would trigger followups along the lines of, "how would those factors affect the size?" and "what bottlenecks might you expect?" and "could it ever be faster when split among more machines?"
It is the one I mention above.
Perhaps a truck drove by every time you saw the mirror rattle?

In some US states, too; many of our states have a code modeled on the Uniform Commercial Code. In Massachusetts, at least, all items come with an implied warranty of merchantability and fitness for purpose, e.g. that it's worth selling and useful. Sellers cannot legally waive those warranties.

As a buyer, my only responsibility is to allow the seller to pick up the item from me. If some site tries to pull a New Egg on me, I point them to the relevant laws, and make a very gracious offer - not only will I allow them to pick the item up, I'll even pack it all up for them in a box.

Lesson: Check your local laws before assuming that these "no returns" or "restocking fee" policies have any weight.
