The methanethiol they add to natural gas is about equally toxic. The use the different chemical so you know it's natural gas and not something else. Methanethiol occurs naturally in the body, so small concentrations are harmless. High concentrations are deadly. Methanethiol, like H2S, is heavier than air and it may pool in low lying areas.

I've only been gassed once. It happened earlier this year from a fumarole in a geothermic area. I breathed the vapours for about half a minute when the wind shifted and ended up with irritated lungs for the next few hours (my eyes were also sore, but that could have been due to the sun; I was already sunburnt). My breathing peaked in tightness about an hour later. I also had a sore throat. No pulmonary edema. I'm not sure if I lost my sense of smell or not at the time. I do remember some drowsiness shortly after. I figure the concentration was close to 100 ppm H2S. It doesn't take much.

Markets do change though. For the longest time, I was a non-gamer. Then Steam for Linux came out. Two years ago I bought a GTX 760, which was many times the cost of the GT 430 I bought before that. I bought the 760 because it was the best card I could get without upgrading my power supply (which split 12 volt rails). But I've found that the 760 is under powered for driving my 1440p display at reasonable framerates (I have the display for productivity purposes). It's time to build a new computer this year, and I'm probably going to go with a GTX 980 Ti.

Not in all cases. I manage a five figures monthly cloud deployment, and I look at the bill every month looking for ways to reduce costs. Using the cloud is cheaper than maintaining our own data center, before even considering how capital intensive it would be to carry around unused resources ourselves.

If I had to have enough spare resources to handle our occasional traffic spikes, I'd have to spend an extra $100,000 upfront for hardware that would sit around doing nothing almost all the time. But when our traffic triples in fifteen minutes and I need another fifty web servers, they're automatically provisioned and deployed behind the load balancer, and we spend an extra $100 or whatever for the day. Events like that happen maybe five times a year. $500 is a lot less than $100,000.

We also use a similar setup for work queues and scale worker machines based on how long it's taking tasks to get processed. Some hours only one machine is running for a queue, other hours, ten. We use spot pricing, too, on less urgent work, to keep costs down.

At first I was skeptical about cloud computing, but I'm a convert. It works. And it works beautifully. And it saves us a lot of money by allowing us to use a lot fewer servers on an average basis.
