comment What is the best Linux filesystem for MySQL (InnoDB)?
I stand by my statement, MyISAM has drawbacks but there's plenty of good to be had. MyISAM is still boss for read workloads.

comment What do you do when your site scales so much that uploaded_media can't fit on one machine?
Can't say this better. S3 is really the way to go here, S3 also doubles in that it does pretty well as a lightweight CDN (even without CloudFront). Check out how CarrierWave and Paperclip work for Ruby on Rails, should give a nice starting point.

comment how in increase performance on SQL Server?
The answer is never to throw more hardware at it until it works -- I am afraid that there are people who can drop thousands to try and fix a problem without knowing the circumstances.

comment 100% uptime for a web application
@Mike I disagree. With a smaller site you could run a few instances in multiple datacenters and be pretty well insulated from failure on a budget. We run a couple boxes on Amazon West and East, when West failed a month or so back we switched the DNS to be East and had zero-downtime (other than for clients who'd already connected.) The moment you have a massive site you have huge databases to keep in sync over multiple geographic locations which makes a somewhat easy master/slave system into a MUCH harder distributed system. See PNUTS for how Yahoo solved that problem.

comment 100% uptime for a web application
@Matt just because Facebook/Amazon can't do it doesn't mean a smaller site can't do it. A lot of large websites face much harder problems to overcome than a smaller site.

comment Best and cheapest way to host 1000s email addresses for our subscribers
Google Apps if you don't want to host it yourself (1000s of barely used emails will hardly make a dent in a server)

Yes, if you have 4 cores and you max it out, you'll be using 400% CPU :)

comment Dealing with HTTP w00tw00t attacks
It does use a table. However I simplified a lot of it as it was tailored to my system.

comment Dealing with HTTP w00tw00t attacks
Yes, I have it scan the Apache error logs for any "w00tw00t" IPs and add them if they don't exist, though for simplicity I didn't add the check for duplicates.

comment Where can I buy a good rackmount workstation?
They're nice, but even with ECC, it shouldn't cost another 1.7k for 24gb of RAM.

comment What is “Cloud Computing”?
I'm aware of the negative reputation this would create, but what most call "Cloud Computing" is not.

comment Can I configure the Windows hosts file to use IP address plus port?
They're still going to the same address, the port doesn't even factor into what hosts does. The port will still work, you can run them in parallel.

comment Linux - Help, I'm running out of inodes!
Reiser is excellent for tons of tiny little files. I'd go with that.

comment Block access to a website in Linux
This is more of a serverfault question, but short answer: yes you can use iptables to block traffic to facebook's IP.

comment Open Source Crawler
Belongs on StackOverflow. But to be helpful, you need to seed your crawler with links and then let it explore. If you wanted to explore sites from your city, you'd need to start with a say, "Boston" portal type site and go from there. There's no real master list or API for it, it's clever programming and focus upon target sites.

comment Why are my php extensions being compiled for PHP4 and not PHP5
+1, I usually just call the proper phpize, I keep my "other" PHP in its own prefix making it simple.

comment Share file system between VMWare Linux and Standalone Linux
+1 Nice answer. NFS is the route I went in this situation, with a little tuning and tweaking I managed to get respectable performance from it.

comment HP DL320-g4 Hard Drive
+1 informative and succinct I too would be surprised. If they're SATA drives it should work just fine. :)
