So where do we draw the line between rights that only adults can have and rights that everyone can have? Since the legislature has decided that free speech doesn't apply to children, why not remove other rights as well? Why give children any rights at all? Why bother giving them a fair trial if accused of a crime?
(Now that I think about it, children are already unable to vote, buy "restricted substances", etc. In fact, even those under 21 can't buy alcohol. How ludicrious.)
You are not encouraged to withhold information. Programmers who create security holes will suffer if those security holes are disclosed; good! They obviously need more incentive to check their work. The security holes are their fault, not yours. If you're worried about them shooting the messenger, post anonymously.
I initially thought they only blocked you from calling real telephones in China Telecom territory, but I guess they are IP filtering as well, so you can't even use Skype IM. If this happened in America it would be Blotto Box time:)
That's OK, though. China continues to claim that they want to play along in the world economy, but moves like this reinforce the notion that they're just a third world dictatorship. Effectively isolating themselves from the rest of the world by prohibiting cheap communications will ensure that their government stays in power, but it also ensures that they'll never be a world power.
I don't need to call anyone in China anyway, but if I ever visited I would be upset that I couldn't use Skype to call home. I'm not paying $1/minute in this day and age; it's not 1920 anymore. Like I said, though, that's OK -- I'll take my business elsewhere. Hello India or perhaps Singapore.
I do not think the iPods use voltage follower output stages. I have built a few headphone amps that incorporate this feature, but it draws a lot of power and takes up valuable board space that's not an option. So it's likely that the iPod targets ~100ohm headphones and screws everyone else over. I will admit that both my iPod and Powerbook sound good though my amps, but could probably be better if there were better output stages.
When you view this in your mbox-reading program, you'll see two messages, even though only one message actually arrived. Oops.
The MTAs have various ways of averting this problem, like adding ">" in front of lines that look like headers. But, some won't escape already-escaped lines (like "> From: jon"), and screw up the content when the mbox is viewed. Also, try using mbox over NFS. Bad.
Maildir guarantees that each message that is received is in its very own file. This means that everything that the sender sent is in the e-mail verbatim, AND that anything else isn't.
This is probably not what you asked, but yes, the filesystem does do a good job ensuring mail integrity. A database might be able to do that, but not as easily as "cat message > file" does.
> you could do the entire thing with MySQL if you REALLY wanted to
I am so tired of people shoving everything into relational databases. What queries are you going to run against your database, anyway? SELECT * FROM messages WHERE read=0? Try "ls new" in your maildir. The reason things never scale right is because people design things to be "new" and "cool" like putting their e-mail into a relational database. No. Just use the filesystem. It, and its supporting tools, have been around for 30 years! It Just Works! It doesn't use any userspace memory! There are no permissions issues, because the kernel controls the permissions. It's the optimal solution.
The filesystem is really really efficient (for e-mail) and really really reliable.

This is placebo. The sound coming from the Line-Out jack is amplified to 100% by the iPod's internal amp. I have done some serious listening through the headphone jack (with and without external amps, and with rather good headphones - Bayer DT880s and Sennheiser HD650s). The best sounding iPod is actually the shuffle (unamplified)... it has really clean bass. The mini is sloppy generally, and the regular iPod is pretty solid. The Powerbook output isn't that great, the iPod is noticeably better. I have looked at waveforms with my oscilloscope that confirm these results -- the output stage caps on the mini and Powerbook discharge too quickly, making a 20Hz square wave look triangular. Not good. The shuffle does fine though! (I'm told it uses a 2-transistor push-pull output stage, but I'm no audio amplification expert.)
Here are some results similar to mine (I haven't written mine up due to lack of interest and time:)
The software companies are only doing this so software patents aren't eliminated completely. By pretending that their useless patents on XOR are helpful to the Free Software community (and thereby looking like the "good guys"), they keep the "good" patents to themselves. If they didn't give away their worthless ones, people would start questioning the software patenting process, and probably eliminate it.
Don't support this. Vote to abolish software patents completely! If mathematics can't be patented, why can algorithms!?
Nothing is stopping you from writing a perfect clone of TeX -- all the details are published. However, nobody knows what bit 3 in byte 7 of MS's.doc format does, so you can't clone it. Or make any other software be able to read all the data in the file.
And your idea of pumping CO2 and pollution into the atmosphere is pretty darn reprehensible. Guess what, if people want to use electric cars or fuel-cell cars, that's great. Problem solved. But frankly the technology doesn't work well right now, and until it does we need a stop-gap solution.
> Oh good. I sure will enjoy having the price of my transit pass increasing with additional fuel costs. That'll be great fun!
I'm sure the bus company doesn't pay taxes on fuel. And if they do, I'm sure they can bother the state until they lower the taxes for them. Fuel tax is designed to hurt the single businessdroid driving to work in his (or her) Hummer an hour each way a day. That is plain wasteful, and it should hurt financially to do that.
Higher fuel taxes don't hurt much if you don't drive very much or if you carpool, which is what you should be doing anyway. Ideally you live close enough to where you work or go to school to walk or ride your bike -- that is the point of cities, after all.
Maybe you guys need to move, then? I live about 10 minutes away from where I go to school (and about a half-hour away from where I work, but taking the train is much faster than driving would be... most of the time).
Ah, so now anyone that likes anything other than heterosexual vaginal intercourse is a pervert and should never be allowed to be in a relationship. In fact, if you've ever looked at anything other than Playboy, we should just execute you now.
Nice to know we live in such a progressive society.
> The extra taxes can be used to fund school buses or mass transit, or reduce the tax load on the parents (Ok, admittedly, in an ideal world;-)
And I assume that the public transit operation companies do not pay tax on gas (since they're already government subsidized). With an increase in taxes, driving your hummer gets too expensive, but mass transit stays the same price (or gets cheaper since there is more subsidy and more revenue from the farebox).
Basically, selfish, lazy people who drive giant fuel-inefficeient cars suffer, like they should. If you want to ruin the environment and flat out waste then at least the state can benefit from your gluttony.
(Think about how nice cities would be without streets -- parks everywhere, no pollution, etc. Petroleum is something our society needs to be weaned off of. Not later, but NOW.)
Personally I wish gas was more expensive, so people would be forced to take mass transit. With ridership up, the public transit systems would improve and everyone would leave the 1920s behind (driving is cool!) and save the environment at the same time.
Just when I thought PayPal might be worth doing business with, this. They must have a world class PR department over there -- "Hey guys. Everyone thinks we're evil." "Oh, I know, let's freeze the donations for the Katrina victims. Everyone will think we're great after that."
Absolutely amazing. I hope Google uses this as an opportunity to launch GMoney or whatever they're calling it.
BTW, good spelling/. editors. `Aweful', you could say.
I don't know what you're trying to say here, but you don't need to be a lawyer to have an opinion on what laws should be. This is a democracy -- the people are supposed to decide what laws they agree to. The GP thinks that segregation was illegal. It doesn't matter if that holds water legally, or whatever; it's what he thinks. Is that a problem?
If everything thinks something is legal, and the Supreme Court decides that it isn't, the Supreme Court is wrong. (Like MGM v. Grokster. Sorry guys, you're wrong. So there.)
I'll bet the one that's 500% better cost 500% less, too. I've never understood textbooks -- I've paid $150 for some absolutely worthless ones and gotten some excellent ones online for free. This semester I am only taking 13 hours, and 3 of those have an online textbook (Discrete Math, info at http://cr.yp.to/2005-261.html) but I still ended up with $500+ of textbooks! What really hit the wallet this semester were music theory textbooks. $60 for the text. $50 for a workbook. $70 for this tiny little song book for ear training class. $100 for the piano book. I didn't even bother to get the $125 CDs for the piano book. $125!?
(As a sidenote, the most I ever paid for a math textbook in Japan was 1300 yen -- about $10. Then you go over to the English section and the books are $200. I don't get it.)
$DATADIR can be written to by an arbitrary user. Arbitrary user creates $DATADIR/foo/passwd. find comes along and adds $DATADIR/foo/passwd to the arguments list. In the mean time, while the other 500,000 files are being found, the user removes $DATADIR/foo and replaces it with a symlink to/etc. Now rm removes $DATADIR/foo/passwd, i.e./etc/passwd.

This is the whole point of a maildir. Each message is in its own file, so a message like:

Hi, this message is going to ruin your mbox:
From: your boss
