For those people who complain about $250 annual fee, just think about how much a plain old phone line would cost. Regarding the $750 hardware cost, if you build 15-way video conference system and sell it with $200 operating margin and one y

This is largely a showcase of stupid economy in United States. If you look back past 20 years, there really isn't any meaningful economy growth except the high tech industry. In most cases, you simply higher price for the same house, t

Tariffs is a meaningful way to adjust trade balance. Whether it works in specific situation is up to debate. This is similar to how U.S. uses income tax cut/raise to adjust economy growth and deficit, and the result is hard to predict.

Assembly line in China makes sense. VW and Audi have been there since 80s. Anything more than assembly line would be very questionable. It is much like how Apple builds iPhone in China, plus many others.

Chrome is more like Java or .NET runtime than C runtime. You can build full blown apps as Chrome packaged apps. Google has not polished it very well. If done well, developers can use it to build apps that run on Windows/Mac/Linux

I think asm.js is the greatest runtime design that I have seen over past 20 years. It gets the job done cheaply. That is the ultimate goal for any runtime system. It is not designed for human to write asm.js code manually. On the other hand

The Internet access cost tends to be higher than advertising cost. You can just compare revenue of AT&T to Google. I pay about $600/year for cable internet, and my advertising value is much less than that. As long as bots pay for t

If we want sustainable nuclear energy, the only solution would be fast reactor that can burn nuclear waste. Politically, it is near impossible to find a place to build nuclear waste storage. Nobody know how safe is such a storage. If we can

Variable encoding is absolutely good choice for i18n. It forces you to give up random access, which is nearly impossible for i18n text processing (just thinking of a vowel followed by 2 or more accents). i18n libraries, such as popular rege

The answer is pretty simple: the Google+ deciders don't get social. They think very differently from their users and they refused to listen for past 2-3 years.

Some people wanted to build optional-typing language for real world for decades, and finally made it. That is a great achievement. From product point of view, Google would be much better to port Android Dalvik to Chrome. You can run GWT Jav

This is absolutely great for Microsoft and its employees. Grade by curve creates internal friction that is harmful to the team. I am a manager in a large company. I always suggested to grade by performance against job level. There is writte

By running at zero profit margin, Amazon is essentially growing itself as fast as it can manage, i.e. reinvest every dollar. Its current revenue growth is even faster than Google. That ensures itself as the biggest ecommerce platform for ye

Yes. Capital expenditures don't disappear. You can buy a piece of land to build a warehouse. You can sell the land to get money back if needed, so you can't report the money for the land as loss.

It is a common misunderstanding. Xiaomi updates its beta channel once a week, and stable channel once a month. It is still an amazing pace though.

"the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel" means it is at least 4 orders of magnitude away from being useful. Since we still depends on nuclear power for de

If Windows has good enough support for symbolic link, this wouldn't even be a problem in practice. There always is some way to solve the problem other than declining it.

The success of Surface Pro largely depends on other people's failure. Nexus 10 is $399 with 2560x1600 display. Many decent Windows 8 laptops are selling at $600. MacBook Air weights 2.4 pounds vs Surface Pro 2 pounds. Technically, it i

It happens to most OS updates. Wait 24 hours for things to settle down, then measure again. On Android, some app may go crazy after update, you have to reinstall it to get out of bad state. I have seen it too many times. Not sure how to tro

It is tricky to manage any large company. The more tricky problem for Microsoft is that it heavily depends on old business models. A significant portion of Microsoft profit comes from Windows and Office. Other companies, like Google, can of

Most Google services are blocked in China by Chinese government. Chinese companies, like Xiaomi and Baidu, want to build their own ecosystems to make profit. Their management said so publicly during talks that I attended in person.

You missed a critical issue. Carriers don't like fully controlled verticals like Apple, as they don't want to compete on a fair battle ground. Apple is too powerful in US today, but no carrier wants another Apple. Several friends

Considering the cost, time of construction, time saving, the project doesn't seem to make much sense. China already dropped maglev due to high cost. On the other hand, Japan is making very slow progress on cleaning up its nuclear mess
