After 4 years of using both PostgreSQL and MySQL, I'd say that one of the biggest differences between them is their extensibility.
If PG lacks a feature, you have a very good chance of finding a script or an extension which implements equivalent functionality. Materialized views, ordering by different locales and hierarchical queries are some examples of this.
On the other hand, if MySQL doesn't have a feature you need, you're pretty much screwed.
XSLT, on the other hand, belongs on the server, not the client.
This is only true because some clients don't support it. But because such clients are pretty rare in the world of business apps, most of us prefrer to ignore them over doing their work for them and simply list compatible clients instead.
Uh, you mean displaying the XML source? Get a source editor, man.
No, I mean building DOM trees with JS and serializing them to XML, without loading large JS libraries or pasting tags together.
Last time I checked Opera (8.0) had these problems:
- No XSLT support - CSS is not the only stylesheet language out there and FF in IE both support it.
- No support for building arbitary DOM trees for in-browser XML generation (also supported by both FF and IE).
- It took seven tries to succesfuly import a certificate. Sometimes it would show up in the cert list, only to disappear after a restart.
- It has no support for digital form signing. (FF provides crypto.signText function and there are numerous free components available for doing this in IE)
- When using SSL with cert based authentication, everything got slow. Really sllooowww. It took 30 seconds to load a page over LAN and several seconds for JavaScript events to fire.
- JS errors are completely useles. They basically say: opps, something went wrong.
I'd be glad to hear about solutions to the problems listed above, but until then, I'm convinced that FF (and even IE) is a much better choice than Opera.
The early trojans (like NetBus & pals) would copy the passwords from input fields when you typed them in. I'm not sure how things work nowdays, since newer versions of Windows don't allow this anymore.
Why is PHP become more like Java, when the PHP developer community seems to want anything but that to happen?
That's because most of the PHP programmers are uneducated writers of throw-away code. They are people who use PHP because they can make dynamic pages without needing to really learn anything; people who mix HTML and SQL; people who never bother to check for errors; people who think register_globals was a great idea, because they didn't have to type "complicated statements" like echo $_POST['somevar']; and the list goes on and on.
The most common argument I hear against PHP becoming more like Java is that now there are so many new things you need to learn. But this is not due to changes in the language making it harder to write crappy code - that's just as easy as it was before. The main reason for needing to learn new stuff seems to be the increasing number of competent programers in the PHP community who put pressure on the incompetent ones, who in turn pound their little fists on the table and cry that PHP is acquiring too many features from other languages. I'm sorry, but knowing the difference between "if" and "for" statements does not make you a programmer.
Ripping off Java is probbably the only real chance for PHP to be taken more seriously in the business world. After all, it worked for C#.;-)
In windows 2000 you can open the device manager and disable any piece of hardware, including the trackpad. I'd be surprised if this wasn't possible with other operating systems.
Interesting stuff. I wasn't aware of such functionality being available under Linux. Thanks to everyone who suggested LVM.

Umm, why would you do this?
Because using an index requires random data access which is more expensive than sequential access. There is a point where doing an index scan takes more time than just going over all the records in a table (example: small tables, condition matches many rows, etc). Any sane query planner should/will choose the faster method.
I see one of the topics covered is backing up data. Would somebody care to explain how to make a consistent backup of a mysql database?
Plain mysqldump does not export consistent data across tables. While you could lock all tables for the duration of backup, that's not likely going to be possible if you're aiming for "high performance". Mysqlhotcopy only works for myisam tables and simply tar-ing up data files is just asking for a disaster to happen. So how do you make a consistent backup without setting up a dedicated replication slave for this purpose?
(No, this is not a troll; I am in fact looking for a good way to back up mysql data on my server)
My first instinct would be that the HTML parsing engine in Internet Explorer was written by a different team of programmers than worked on the rest of the software
I's say the same about outlook express. Most security holes in OE were due to bad "glue" between components. And if I'm not mistaken, most holes in IE are also caused by bad integration.
It sure looks like the expert programmers create components which are then bolted together by an army of "learn programming in 24 hours" drones.
Car companies keep showing us all theese incredible looking prototypes, but why won't they sell us a car that looks the same? By the time a new car makes it to the salons it looks almost exactly like all the other damn cars you can choose from, and attaching a baboon's but to the rear end is considered to be a bold new design direction. yech.

Not only that, but a new version of PostgreSQL is also being released in about an hour. Get ready for a database news overdose. :)
