If flying cars were available tomorrow, they would not sell in any meaningful numbers.

Nobody, or near enough nobody has the means and inclination to fund the raft of licenses required to fly/drive one, and if they did they wouldn't be able to get insurance, or flight clearance in any way that would render it more useful than any other light aircraft.

James May of top gear fame went quite deeply into this in one of his many lucrative geek-out shows, I think it was 'James May's big ideas' S1E01 'Come fly with me'
There have been plenty of flying cars; the shortage is in flying-car ready consumers.

When someone else wants to use firefox start it as:

Give them a fresh profile, set it not to ask this again and it will default to theirs.
Run with the -p flag again to select your own profile when your guest is gone.
I do this regularly, it's easier than giving people their own userspace on my machine, and has the nice bonus that everyone gets their own awesomebar.

Unshiny android?

Htc have launched an android phone with their new Sense UI
If you've ever used a Htc phone before, you'll recognize it as being very similar to their awesome TouchFlo 3D interface for windows mobile.
The G1 is too underpowered to be serious competition for the Iphone, but things are getting better.

I very much doubt there is a city, let alone a country in the world where the majority of smokes smoke two cigarettes a day.

You're comparing apples and oranges anyway.

Smoking one or two packs of joints in a day is probably impossible. You'd be asleep before the second pack ever happened.

If you disagree with this statement, you just aren't smoking the right strain.

Cannabis is a wonderful plant, it should by all means be legal, but should not be left uncontrolled.

Under 18's that smoke are at risk of developing mental illnesses, I've seen it in friends and relatives.
As far as I'm aware, this risk isn't present with tobacco or alcohol.
If the developed world is to legalize cannabis, we need a way to stop it falling into the hands of our children (ie selling it prescription only, or to licensed individuals only.)
I'm thinking if we do this, street dealers will still have a market in u18's and individuals unable to get a license or prescription, so the cartel problem won't disappear overnight.

In the UK, where tobacco is heavily taxed, a similar, albeit smaller scale phenomena already exists.

Mod parent up. I was about to post this observation myself.

The HHTG series got less funny as it progressed, as Adams grew more frustrated with writing.
He hated writing with a passion, and often had to be locked in his office to meet deadlines. Since the fourth and fifth books of the trilogy were new material rather than expanded radio scripts, they suffer from this far more obviously - it took him eight years to write Mostly Harmless, with the other books all being released within two years of each-other.

I must also note that Adams already started on a sequel, (prequel) called Young Zaphod Plays It Safe Wiki

Unfortunately he suffered a TEF at the gym before he could finish it; his final joke.

If you have genuine interest in his works you'd probably benefit from checking out the soon-to-be-released BBC remake of Last Chance To See Wiki - A short documentary series following some of the worlds most endangered animals, Due to start September 6th on BBC2

The entire radio miniseries is available on the BBC website linked above, and is drenched in Adam's usual style.

Nukes are already outdated, as of about six years ago.
Why deal with fallout when you can just drop eight and a half tonnes of H6 on your enemy instead?

I fail to see why the targets of this move, the gangs of scum that hang around the outskirts of UK cities having their recruitment videos taken down is such a bad thing.
These videos show hooded/masked youths, bragging about their violent crimes, and showing off their hoards of stolen/black-market guns and knives.
Taking down the recruitment videos helps to stop the gangs growing, it's part of a wider tactic police here use to disrupt the social lives of the gangs, forcing them apart.
Of course, if you'd rather the scum of the British underclass were allowed to rob, stab shoot, and deal drugs freely, you're welcome to take them, and let them do so in your own country.
We're sick of it here, especially in Liverpool.
