Google has a crappy dysfunctional checkout system and make no attempts to collect your payment details until you decide to bite the bullet and buy an app. At that point, they make the process painful and unsatisfying so that you are put off from ever trying again.
Huh? Are you referring to the app market or something else? The google mobile market is painless and easy to buy apps. You hit buy and it charges your card on file. You get the app. Done and done. What could be easier?
I check my new iPhone app and lo and behold, there's a checkpoint on the only highway between the bar and my house. I don't want to spend the night in jail, so I take a cab instead.

End to end communication when both endpoints are behind NAT is a tricky problem. I don't know the skype protocol, did skype actually solve the problem, are the sessions truly end to end, NAT to NAT without the central server doing any proxying?
SIP by itself cannot solve the problem when both endpoints are behind a NAT without specifically forwarded ports, but it does work well when properly configured and only one side is NAT'd, which is classically the case with any protocol.
Halfway decent is hard to define. If it works, it's halfway decent at the minimum, heh. Most of your off the shelf consumer linksys, netgear, etc routers will handle passing sip just fine. Every so often you may run into a box that just fails miserably.

I agree about DST, though I don't see the point in being a half-hour out of synch with GMT. It just makes the mental math harder.
I'd say just do away with daylight savings time the next time it comes around. You'd need to give everybody at least a year's notice anyway, so that devices can be updated and gotten into the retail channels.
One year? That's it? I think we would need at least 5, maybe even 10. Have you seen how long it's taking to roll out ipv6?:P
I've got a single core 2.2ghz machine with 2 gigs of ram running Linux (of course). Slashdot used to fly, now it sucks up 20% cpu with just a tab open, doing nothing... not even scrolling around.

The biggest problem with making a mysql compatibility layer on top of postgres is dumbing down the whole interface to be compatible. It would involve removing so many items and breaking many standards. You might as well just keep using mysql in the meantime while you port your app to postgres.
And... the whole point of a compatibility layer is so that you can either 1) run your whole app as-is and keep developing as-is on the layer on top of the system. So now you have zero gain from moving to postgres, you're still using the same old cruft... or 2) you want to run some code in the compat layer and some code in the native layer. Now you open up a whole huge can of worms. Now you need to specify which tables/functions/etc are running in which platform, the screwy mysql one, or the real postgres one. Unforeseen interactions between the two would be full of fun surprises I can assure you.
Off the top of my head I can think of a few horrid problems with mysql that would have to be ported. Silent truncation for instance. Insert 30 characters into a 20 character field and mysql will gladly accept it, and not even throw you an error. Now there is a flag you can turn on that will give you errors on some of these issues, but not all of them.
There's a bit of a history of silently doing nothing with bad data, or silently doing nothing when there's a problem in general. See: http://use.perl.org/~Smylers/journal/34246
This next writeup is a year old, and obviously some shortcomings of mysql have been fixed up... but many of these issues still remain. The issues listed that have not been fixed.... and then some, would have to be ported.
The biggest problem with everyone staying on ipv4 and natting until the cows come home (which will be never... these cows will *not* come home for ipv4) is that all of a sudden you have thousands, millions of end-users on nat going through overloaded 4 to 6 proxies.
And if no one switches to v6, only rich content providers will be able to afford direct ipv4 And then, due to the fact that end users will certainly not have a public ip address: - streaming media of any kind will eventually be unusable due to overload of aforementioned 4 to 6 gateways - you can't do end to end links (like with voip and video conferencing)... you would of course be able to pay your isp for the privilege to use *their* voip. - bittorrent and friends will vanish - self-hosted online gaming will go the way of the dodo and players will be at the mercy of the corporations for whether they can play their old games online or not. - the LSNs will probably be blocked by most mail servers to prevent spam. You say that's good? Watch the price of email hosting and hosting in general skyrocket because of the high fees companies will need to pay in order to purchase ipv4 addresses from each other. Prices of ipv4 *will* go up due to supply and demand. - the lack of cheap addresses will force small services out of business and will force many free services to shut down - the lack of small providers will leave only the big ones remaining - with the big players the only ones left on the internet, they would love to turn the internet into a dumbed down content distribution system like cable tv... lovely

I'd say for most real-world use, there isn't any significant difference between them anymore.

Thinking about choosing Postgres or Mysql is like pondering about whether to bring a war tank or a volkswagon bug to the battle of the bulge. If you want to write real database applications, with real consistency and functionality at the database level, you will pick Postgres. If you want to do all the work at the application level (bad), put up with blind truncation (bad), and put up with a lack of some basic features... by all means pick mysql.
The only reason I can fathom that companies are using mysql for any large scale database system is that the project probably started out simple. It grew and grew and became "too big to port" to anything else. Now they are stuck with mysql and its limitations when they should have been with something better.
I used mysql for many many years. I stayed away from postgres because for some reason I had the impression that it was really complicated. Once I had started using posgres, it was an amazing feeling of new freedom that I had.
I totally agree that text message prices are quite ridiculous, but ignore that for a moment and think about your usage for a month.
If your plan says 25 cents per text message, and you routinely send 500 texts a day, only a complete dimwit would be surprised by the bill at the end of the month. If that same provider had a plan for unlimited texting for 10 or even 20 dollars extra per month, then it's totally worth it if want to stay with that provider, since you won't pay out the nose for texting.
On the other hand I do agree that you should be able to set a cutoff limit if you are not on an unlimited plan so you don't get insane charges.
And to play devils advocate, the services prices for minute overage, text messages and etc are always spelled out in your service agreement. And all the carriers I've dealt with have some way to check your current minute, text and data usage. So if you keep an eye on it, you won't get surprised.
I was in high school 9 years ago. Lunch was LOCKDOWN. You had to present your school id to get in, which was color coded to define your appropriate lunch period. Once in, you needed just about a medical emergency to get out unless the lunch period ended. The "recreation yard" felt more like a prison yard... it was a 50 by 50 paved concrete yard with two potted trees that was part of the interior of the school. The only way out of the yard was back into the cafeteria. Mainly people went out there to smoke.
I never ate in the cafeteria, so the easy thing to do was to just skip going. I got friendly with a teacher who ran peer mediation, which was about training kids how to be moderators when two other kids beat the crap out of each other and had to resolve their conflict afterwards (or face detention). So I would just hang out in his office during lunch... do homework in peace, nap if I needed to, and basically just relax. It was a much better experience than sitting around the goths smoking pot in the 'yard'.
School can be a very uncomfortable place to be in, and an almost impossible place to learn in.
HAHA. I wholeheartedly agree. I started my real learning in college. All through public school I hated it. I hated sitting though classes where 1/2 the class time is sucked up taking attendance, 1/4 the time is spent going over the homework the night before, and the last 1/4 is spend shoveling new stuff out.
The best/worst was experiencing a first year teacher for the first time. Not that all first-year teachers are bad, which is hardly the case. She taught science and math in Junior High. Mostly the class time was wasted by her feeble attempts at gaining some semblance of control by assigning "copy pages 200-220 from the text into your notebooks".

Since I was born in this country I have never seen so much lawlessness by financial institutions, politicians and law enforcement.
If this continues the USA will break up. If the USA becomes politically unstable we could see civil war.
There are already indications of this as state legislatures ignore their constituents and yield to the criminals in Washington.
We have states desperate to save the currency Washington is destroying, by declaring new issues of monetary and economic rules in their own states.
Meanwhile you have Federal powers trying to make it illegal to put anything other than Federal Reserve notes and arresting anyone who dares try.
A confrontation is coming between those who have looted and stole everything in this country and those who have been stolen from.
Be sure you pick the correct side when the crap hits the fan, because it is going to get very very ugly.
