is MySQL really an alternative to Oracle?

I mean sure it 'technically' is. But someone likely to use MySQL isnt looking for such an enterprise product such as Oracle and people looking to spend their money on Oracle can't/wont settle for MySQL. I thought this was basically what the EU said anyway.

Comment Re:How is using so many VMs more efficient? (Score 5, Informative) 122

Its more than that.

Most machines run at around 10% of all possible utilisation. Often web servers will run at less than this. In a datacenter you have two options a) run hundreds of very slow cheap machines each running one instance of your webserver. b) consolidate lots of machines onto one powerful box and running it at 70-80% utilisation.

Option b) has the advantage that should a website get hit heavily (maybe because its been linked too on /.) then you still have the beefy hardware to cope with it. You will also find heating bills go down. You'll usually even get the costs of the hardware down as well.

If your still not convinced then look at the work by most VM software manufacturers who are making it so the VM can move around on physical hardware. Now if your hardware fails - the VM and OS does not. It just moves off somewhere else and continues to operate with little/no drop in performance or uptime.

Now, if suddenly everybody had a quantum computer that could break RSA in polytime, there might be a point to this, but they don't, so there isn't - not that I can see.

If suddenly is in say 10 years time. Then doing this research that will be much more feasible in 6 years time seems pretty smart to me. Just because the technology isnt here now doesn't mean it isnt worth preparing for its arrival

Being a student I still use Wikipedia alot of the time.

To use it successfully you just scroll to the bottom and look at all the pretty references on a subject. 90% of the time you'll find the actual journal articles.technical papers/books that you were actually after.

Wikipedia is a source of infomation. Not an information store.

Opera do not even have a message saying they Pass at 100. Actually Opera seem to feel its something their browser shuld be doing anyway - not a "goal"

Although I agree its nasty marketing - Turbo is a real benefit to people on slow net connections, such as a mobile. It basically proxies through Opera's servers and compresses everything before sending it to the phone. So as much as a clog is something too big increading pressure on a limited throughput - Turbo does unclog your connection

*Sorry Karma*

Seems to be working in Opera 10 (alpha) as well. So is it news when Firefox does it - even if its last?*

What I think is news is there seem to more browsers that support the tag that websites that use it. Must be a first for a new feature of HTML.


*Yeah yeah I'm discounting IE.
