If it actually crucial, they can pay enough to guaranteee they get the visa.
joelwilliamson··on The U.S. wind industry now employs more than 100K people
If you write the required resources as absolute numbers, of course it looks like a huge investment. If it was rephrased as percentages of global production over 15 years, the numbers look much more manageable.

2% of global steel production 1% of global coal production 0.3% of global oil production

joelwilliamson··on TV May Die Soon
The number of gas stations declined 25% from 1994 to 2013. I'd hardly call that doing fine.

joelwilliamson··on The 640 K Barrier
It's still happening today. When AMD64 was introduced, it ignored the upper 16 bits in the address. JIT compilers take advantage of that fact and use that space to store information. Now that we're bumping up against the 48-bit limit, special handling will be needed to ensure applications that assume the upper bits of the address are unused don't get allocated memory with the high bits set.

joelwilliamson··on Amazon soars to more than 341K employees, adding 110K people in a single year
At 50% per year, it will take 25 years to grow by a factor of 20,000.
joelwilliamson··on Peak Millennial? Cities Can’t Assume a Continued Boost from the Young
> We're talking thousands of apartments, literally.

To add some more concrete numbers, in 2015 there were 14,357 units completed in New York. Permits were issued for 56,528 units. (Only 20,000 permits were issued in 2014. They were down 65% in Q1 2016.)

For a city of over 8 million people, I would expect 50,000 units/year to be the sustainable level. 20,000/year seems quite low.

joelwilliamson··on China has built the world’s largest bullet-train network
I just checked the Eurostar prices. A ticket for London-Paris tomorrow and Paris-London on Wednesday can be had for $247. If you book a month ahead of time, it's below $50 one-way.
joelwilliamson··on AdNauseam Banned from the Google Web Store
The case against Standard Oil was pretty explicitly because of anticompetitive behaviour, not price inefficiency.
joelwilliamson··on How Apple Alienated Mac Loyalists
100Gb ethernet has been around since 2010.
joelwilliamson··on Nestle says it will cut sugar in chocolate by 40%
There is no drought in Southern Ontario. They are drawing well water, not residential water. A farmer could draw that much water and pay absolutely nothing.
joelwilliamson··on SpaceX FCC Application for over 4000 Internet Satellites
Kaiser Motors is still producing Jeeps as a division of Chrysler.
joelwilliamson··on Compulab Airtop – Natural Airflow Desktop
No. 10dB is the volume of calm breathing, 0dB is the threshold for auditory perception of a sound at 1kHz.

With regards to a CD, the decibel measures the gain rather than the volume. 0dB in this context simply means "full volume", while -10dB means 10% of full volume, and -20dB means 1% of full volume.

joelwilliamson··on Poor people pay for parking even when they can’t afford a car
$120K per parking spot is ridiculous. Some construction firm must have very good ties with your city government.
joelwilliamson··on Not Your Problem
> It was really horrible; the lecturer had never heard of agile and forced us into a waterfall process in which 60% of the time was spent documenting requirements and drawing bogus diagrams.

It sounds like the lecturer did an effective job of convincing people how valuable agile can be.

joelwilliamson··on Baidu File System – A distributed file system for real-time applications
That's ordering by native speakers. If you count non-natives, English has far more speakers than Spanish (but far less than Mandarin).
joelwilliamson··on Sculpture of Housing Prices Ripping San Francisco Apart
According to your link, there are about 10,000 new units under construction. That's about 10-20 buildings worth. Not exactly a huge boom.
joelwilliamson··on Five Years of Drought
There will probably never be desalination cheap enough for irrigation, and non-agricultural uses don't add up to enough to make desalination nescessary.
joelwilliamson··on Apple iPhones Found to Have Violated Chinese Rival’s Patent
After the Sino-Soviet split, China was a third world country
joelwilliamson··on Small Modular Nuclear Reactors Overcome Existing Barriers to Nuclear
The exclusion zone is 20km, so the area will be around 600 km^2. Compare that to Lake Mead, which is 640 km^2 and runs a power station with half the installed capacity of Fukushima Daiichi.
joelwilliamson··on Chrome removes Backspace to go back
People would quickly come to depend on their data not being lost when they leave a page, and then be very unhappy when sometimes it is lost.
joelwilliamson··on Washington Should Prepare for Saudi Arabia's Collapse
The Kingdom of Jordan also doesn't cover the entirety of the river Jordan.
joelwilliamson··on Uber losing $1B a year to compete in China
The argument isn't that the government needs Uber to be able to track their citizens, but that Uber being a major player allows the American government to track Chinese citizens.
joelwilliamson··on The Rise of Renting in the U.S
He never said it was easy. It's simple, but not easy.
joelwilliamson··on Python to OCaml: Retrospective
The middle bar looks red to me.
joelwilliamson··on Square Prices Its IPO at $9, giving it a $2.7B valuation
My Firefox renders it as an apple with a bite taken out of it. Probably depends on your font.
joelwilliamson··on Why Tesla's Autopilot and Google's car are entirely different animals
The author didn't justify that statement at all. If we have gone from an error once per minute (cruise control) to once per 30 minutes, and think that level of improvement can be repeated twice more, we will be at one error every 450 hours. A third time will put us at one error every 13500 hours.

Is continuous, gradual improvement the best way to fully autonomous cars? I don't know. But the author's argument is simply that we aren't there yet.

joelwilliamson··on Urban activists set out to sue San Francisco’s suburbs
Are there no development fees in the US? In Canada, municipalities will levy fees on developers to pay for all the new infrastructure. In some cities, this also helps keep taxes low for other residents by paying for operating costs as well.
joelwilliamson··on China Moves to Devalue Yuan
The obvious counter-argument is that home prices would have risen even faster without the construction boom.
joelwilliamson··on A Well Known but Forgotten Trick: Object Pooling
The stack doesn't have to be limited. On a 64-bit system, you can give each thread a couple of terabytes of stack space with no problem.
joelwilliamson··on User agent overrides for top Japanese Sites
IE has spoofed Mozilla browsers since at least IE2. When was the last time you saw a browser that didn't claim to be Mozilla/5.0?
