Speedtest sites don't tell the whole story, especially at higher speeds...
Some of the speedtest sites are only on 100mbit themselves, even those on gigabit are usually sharing the bandwidth at their end... And then there's peering, the interconnect between your isp and the speedtest site might not have 1gbit of free capacity at the time your testing. The end devices (or the software running on them) might also not be up to the 1gbps rate - lots of cheaper gigabit nics can't handle wire speed, long or bad cabling, flash based speedtest apps etc.

I've had a box with 1gbps in a data centre for a few years now, and i can quite happily pull 1gbps doing torrent downloads and from some linux mirror sites, but i get a lot less from speedtest sites and many things download a lot slower because the other end or something in between can't handle it.

You need to test a variety of different things, and at different times of the day...

That's very true, and doesn't just apply to unix based systems... You should not be connecting a system to a public network unless you fully understand and control it, and windows is actually much worse in this regard because its massively more complicated than any unix.

You jest, but that's the exact purpose of many "How strong is your password?" websites.
They get a nice dictionnary of real-life uncommon passwords.

Golden age indeed.

Anybody with sufficient technical knowledge can fake an email to pass a casual user, but most people don't have that knowledge...

Just doing a spoofed SMTP transaction won't change the source ip that the message originates from, which will fail things like SPF checks and likely get flagged as spam (i.e. the recipient may never even see it)... And then there's things like S/MIME and PGP.

Faking a letter on the other hand may require a little effort as you describe, but anyone can do that... It's not really a lot of effort, doesn't require any specialist skills and would be extremely difficult (if not impossible) to prove it was fake.

Okay, thanks for the explanation.
From the title, I thought it's a global study.
It's not like the atmosphere care about the nationality of CO2.

Actually, replacing coal is happening already.

No. What are your sources? Here are mine, from BP 2015 :

I'm 33, and I listened to Neil for most of my life.
Old man, Heart of Gold, The needle and the damage done, Hey Hey my my, out on the weekend, Southern Man.
Those are all good powerful songs. He doesn't always sing perfectly in tune, but I find it acceptable since he really brings emotions to his songs.

You were lucky to get an unsubsidised n95... I had a carrier branded one which was horrendously unstable so the point of being unusable, some features were disabled (like the SIP client) and battery life was terrible.
Debranding it and putting the stock nokia firmware on and it was much better.

What can go wrong with the planet?
Take a look at this "what will go wrong?" list :

"Actively flown" with a one-way latency of 4.5 hours.
Navigating an oil tanker must feel like go-kart in comparison.

Development of Concorde basically stopped...
There was a second generation Concorde under development (http://www.concordesst.com/concordeb.html) which would have improved fuel economy, increased range and decreased noise.
Had development continued then there would have been many other improvements by now too, especially if there had been competing supersonic airliners to spur development.

And companies should locate their workplaces somewhere that people can afford to park (or provide free parking), and somewhere which is within a short distance of affordable housing, and not in the same place as large number of other businesses. They should also make working hours more flexible, and encourage home working.
All of these things would save the employees time and money, and improve working conditions.

Some public transport is sufficiently dangerous that you'd not want to advertise that you have an expensive device like a laptop...
Some people suffer from motion sickness which becomes MUCH worse if you're trying to read something.
Often you don't get a seat and have to stand, it's difficult to use a laptop while standing.

For me, using public transport is dead time. When driving i'm concentrating on the act of driving, which at least keeps my mind occupied, when sitting/standing on a train i'm doing absolutely nothing.

And centralized business districts are the biggest cause of travel problems... Thousands of people converging on the same place at the same time, all forms of transit get ridiculously congested and painful to use.
If things were more spread out, both in location and working times then most people could have a short and not too unpleasant journey to work.
