This is stuff you need to handle yourself because php doesn't do it for you.
Indeed, but if you can make PHP do it for you without hassle, then why not? In fact, PHP has a wide array of functions available for just the very thing.
I agree with you on the failover part. Although the server's uptime is concurrent when it was actually put into production (7 months), hardware failure is not if, it's when.
You're also right about it not being a large operation. The hardware infrastucture is pathetic, but we are getting a fair amount of traffic.
The original purpose of the site remains the same today.
Personally, I'm guessing that the original site was over-engineered by imcompetent programmers. The purpose of my post wasn't to bash J2EE and/or Oracle or to say that FOSS is better, I was simply relating an experience I had to the Slashdot crowd thinking they might find it interesting.
Basically, I'm a firm believer in the right tool for the right job.
You're right, we (as a group) can't make any solid conclusions from this data. One of the major problems is that I never saw the old code or know anything about the websites previous deisgn.
However, from my experience, in the future I will always recommend the setup I've already explained because I know it works well.
Give me your PHP/MySQL solution and I bet I can bring it to its knees with a few properly placed bad queries and/or data structures.
Of course, bad code will bring anything to its knees, no point there. That's the nice thing about advanced database methods; using stored procedures, transactions and the like can help maintain data integrity even if you've got a couple of bad developers in house, although it can act against you when considering performance.
To make any conclusions about technologies based on your one example would be a crime...
I could site other examples from co-workers or friends, but this is one example that has affected me personally. Do you have any examples of replacing FOSS with JSP and Oracle using weaker hardware and seeing an increase in performance?
I am lead developer (well, the only developer) for a major website (+half million page views per day).
When the owners of the website first came to me, they basically had a team of developers who worked around the clock to maintain the old website which was running JSP and Oracle on a total of 5 servers (I don't know the proc, mem, etc).
The website ran like a damn pig and the owners were tired of all the problems.
Basically, they came to me and asked me if I could re-create the entire website using FOSS and on two servers or less, while speeding the whole thing up. I'll be honest with you, I agreed to the job, but I was a little worried. Would LAMP live up to the hype?
I settled on MySQL 4.1.3, PHP 4.3.8 and Apache 2.0.50. First, the owner wanted to see what one system (single 2.4GHz, 2 gigs RAM) was capable of before putting the second one online (which was only an additional web server). A few months later, the site was finished. I was sweating bullets when we switched the DNS record and the requests started to pour in!
We've never had to turn the second webserver on. A single processor server (apache + PHP + mysql) handles the entire website, while the load average never climbs over 0.20. Every page is dynamically generated with several DB hits per page and we're talking about more than half a million page views per day (over 2 million hits per day, over 500GB per month), while the server sits not even breaking a sweat.
Now, what can we conclude from this? First of all, JSP with Oracle isn't remotely capable of this project with the resources given.
However, I do know from first hand experience that a LAMP design works well for large operations.
That concept was that everything one needs to know about why private business trumps government projects can be found right HERE.
first of all, I highly doubt that the X-15 cost more than $20 million to make. NASA flew the X-15 to 107.96 kilomters, flew faster than Burt Rutan (4018 MPH) and they did this 44 years ago with inferior technology, chemistry and compounds.
Also, Rutan never made it to the velocity required to orbit, nor had to provide a solution for returning from orbit. If on a difficulty scale of 1 to 100 (100 being achieving orbit), Rutan's accomplishment would rate about a 5.
I'm not bagging Burt, job well done. But saying that NASA needs to die because of Burt's success tells us that you're completely ignorant. Good job.
I was under the impression that all NIC's had a hard coded MAC address.
You can change the MAC address via software in the NIC driver, but that doesn't physically change the hardware MAC, it simply changes what the driver reports the MAC address as being.
When it appears that we "humans" lack even a basic respect for others (such as it is), then it's no surprise that comments like mine score a +5 insightful from moderators in agreement.
First of all, I'm in Linux about 95% of the time. So I have no need of AV. I use a simple iptables firewall script for network protection.
The other 5% of my time is spent playing games. My machine duel boots into WinXP. I don't use WinXP for checking mail, and I use Firefox if I do any browsing. I don't download executables from questionable sites, therefore have no need for AV. I use the internal WinXP firewall for network protection.
I don't think the goal of Spaceship One is to obtain orbit. The idea of flying at 100k above earth provides for very little atmosphere, which allows one to travel at greater speeds with less thrust.
(We're talking the difference between Aeronautics and Astronautics).
By being able to cheaply allow spacecraft to gain altitudes of 100k, this can serve many applications, but mainly it can get a person or thing from one side of the planet to the other in a fraction of the time it currently takes with conventional jet aircraft.
That is the reason why Spaceship One is achieving this goal.
In Saint Petersburg, almost every vender sells each CD for 60 rubles. That's about $2.05
DVD's cost more. They go for 100 rubles (about $3.30).
Here, you don't pay for content, you pay for the CD. So even a double sided DVD still costs 100 rubles. Although the DVD jacket covers are in Russian, most of them can be flipped over for the English version.
Whenever I have friends visit me from the States, I show them one of these street corner CD shops. It's like watching a kid in a candy shop!
As far as I can tell, all of what humans are is in the brain, stored as some sort of information. Whatever you know or remember or think or feel, it all comes from your brain, or nearly all of it.
then what is this 'soul' everyone keeps talking about.
What if you lose 1000 cells? A million? Where is the threshold?
hmm, dunno. maybe you should go ask Keith Richards.
um...where? I'm sure everyone realizes you're talking about Chechnya or (Slashdot is filtering out my windows-1251 encoded chars) and not some German republic somewhere, but I thought I would point it out so no one is confused.

hmm, no idea why my original post was moderated as 'overrated'.
I'm a DS fan, but have been unable to find a website that has more information regarding DS than Gamers.com.
I posted it here thinking that others could benefit from the research I've already done.

here's a nifty site, Gamers.com which has game data, news, reviews and previews for all DS titles.

Am I wrong here?

if that's the case, please rent your movies instead. Your conditions are obviously not satisfactory enough to attend a public showing of a film.
holy hell, speak for yourself, mate.
do you work for MS?
good god, if that's not a poster advertisement for anti-cocaine abuse, then I don't wanna know what is.

well what about life support systems? Do the rules state that you need the ability to provide life support for your two "passengers?"
Does Spaceship One have the ability to provide life support for the 2 passenegers?

oh dear god, i'm crying with laughter!
great tip, I just registered thru them.
By the way, namecheap is currently running a special, so the $5 'whoisguard' service is currently free. $8.88 for a domain, whoisguard included.
awesome deal.

exactly. whomever is running open web proxies are complete morons.
it's no different than running an open relay mail server.
i absolutely swear he wasn't making that up!

Which brings me to the second observation: no litter. There was, seriously, no litter.
and on the other end of the spectrum, we have any Southern California public park after a Cinco de Mayo holiday...
makes me sick.
