omellet··on Solar power has begun to transform the world’s energy system
You seem to be ignoring the most important factor, which is cost.
omellet··on SpaceX, T-Mobile to connect satellites to cellphones in remote areas
If it's TCP then there's an uplink implied.
omellet··on Crypto Wash Trading
It's a way to fraudulently pump the price (or lower the price) of a security. One person with two accounts can keep trading back and forth with themselves, and since crypto exchange know-your-customer measures are trivial or nonexistent, it's very easy to get away with.
omellet··on American Entrepreneurs Who Flocked to China Are Heading Home, Disillusioned
https://www.theguardian.com/world/2018/oct/11/china-legalise...
omellet··on Bitcoin Futures Start with a Bang as Rally Trips Circuit Breaker
It is a huge premium. In reality it should only be the future value of the current spot, given the current interest rate. For other types of futures (oil, grains) that have storage costs or seasonality there are other factors that affect the difference between the spot and future price, but for financial futures (especially cash-settled) it should be nearly no difference for a one-month expiry.
omellet··on Mike Novogratz Is Set for Comeback With Cryptocurrency Hedge Fund
Most people think it's a bubble, and nobody thinks they're the greater fool.
omellet··on Water Found Deep Inside the Moon
It's tidally locked, so you couldn't you put the settlement on the Earth-facing side and not have to worry as much about meteors?
omellet··on Used GPUs flood the market as Ethereum's price drops below $150
Don't cryptocurrency transactions take a lot more time & energy than, say, a credit card transaction?

Or you can thank the English for figuring out how to measure longitude.
omellet··on VIM Pays Excellent Dividends: Learn it early, if you can
I use VsVim in Visual Studio, highly recommended.
omellet··on The .NET Language Strategy
I guess C++/CLI doesn't count as a .NET language? Shame it gets so little attention, it's a fantastic interop language.
omellet··on Nielsen estimates ESPN lost 555,000 subscribers during the last month
Local tv channels have the broadcast rights for the home team area - like SNY in New York has the rights for the Mets. Their contracts specify that they have exclusive rights to the broadcast for their coverage area, so internet coverage must be blacked out.
omellet··on Google and LinkedIn announce massive land swap
Why don't they just build taller buildings?
omellet··on Why do we use the Linux kernel's TCP stack?
The problem isn't locking so much, it's that you have to dispatch to a kernel thread when you're requesting and sending data, paying the cost of that context switch every time. In userspace you can spin a polling thread on its own core and DMA data up and down to the hardware all day long without yielding your thread to another one.
omellet··on Electric cars are no longer held back by crappy, expensive batteries
Now they'll just be held back by lack of a widespread charging infrastructure.
omellet··on How to Clock a Glacier
Do glaciers move continuously, such that they can be measured like this?

Welcome to the surveillance state in your head: http://www.theamericanconservative.com/articles/the-surveill...

He's not a fan of two's complement, I guess.

Bicycles aren't allowed on the sidewalk, either.
omellet··on All the UML you need to know
This should have linked to a blank page.
omellet··on Why Do High-Frequency Traders Cancel So Many Orders?
It's not an especially high barrier if your strategy doesn't require you to build physical infrastructure (most strategies don't require this). You have programmers, hardware, colocation costs, direct exchange connection costs, trading fees, etc. The programmers are by far the most expensive component.
omellet··on One Kenyan Tribe Produces the World's Best Runners
This piece is an excerpt from the longer Radiolab episode.
omellet··on High Frequency Trading Defined
I agree that it's a waste of talent and money, but how is it evil?
omellet··on Senate’s Patent Act is a Big Win for Startups
That would create a corrupting incentive for the USPTO to encourage and accept more patent filings, which is the opposite of what they should be doing.
omellet··on Elon Musk: human drivers are 'too dangerous'
A better measure would be deaths per driver decision, if you could estimate such a thing.
omellet··on Go 1.4 is released
Perforce is not Git-style, it's got a single central repository.
omellet··on Inside the Dynomak: A Fusion Technology Cheaper Than Coal
The article lists several other fusion approaches that are also in development. Does anyone have a real sense of the likelihood of any of these actually working? I'm optimistic, but also naïve about the engineering challenges.
omellet··on Studies find fast traders get data from SEC seconds early
For any amount of time less than it would take a human being to make a decision and take action, it doesn't really matter the latency. Even if the website and newsfeed release were guaranteed simultaneous, the mom & pop investor typically doesn't have a computerized trading strategy, let alone one running in a colocation facility with a single switch hop between them and the exchanges.
omellet··on From Vim to Emacs
Can't you do the same thing with vimscript (or python, if you're using +python builds)?
