"We can usefully describe the way in which people function at work in terms of two modes: open and closed. ... By the closed mode, I mean the mode that we are in most of the time when we are at work. We have inside us a feeling that there's lots to be done ... we're probably a little impatient ... it's a mode in which we are very purposeful ... but not creative. By contrast, the open mode is relaxed, expansive, less purposeful, in which we are probably more contemplative, more inclined to humor, which always accompanies a wider perspective, and consequently more playful." [Creativity is a way of operating, one that is playful.]
me: What date is "Week 39" in graphs? September 23, 2013? Linode: Thank you for contacting Linode support! You are correct in that week 39 for 2013 is from September 23rd to the 29th. me: Let me double-check. The hash mark "Week 39" on the graph means Sep 23. You have a hash mark for "Week 00" which makes me think that the hash mark for "Week 39" is actually Sep 29, 2013. Could you clarify? Linode: Sorry for the confusions. After further review, it does appear that week 39's dates fall between September 29th - October 5th. Since our graphs count weeks as 00 - 51 the 39th week is actually going to be 40th week on the regular calendar. me: Okay, so if I'm looking at the graphs on this page: [URL] The axis mark which says "Week 39" means October 5. Correct? Linode: Yes, that's about where that would be. me: I need the exact date, not an approximation. Please confirm the exact date. Linode: I'm sorry for the confusion, but that is the correct date, but we couldn't tell you exactly which tick mark aligned with the text would mark an exact to-the-second moment in time. That's as specific information as you will be able to get. me: Okay. I just needed the date, not the time. Thanks. Linode: Week 39 ends on October 5th as mentioned.

A personal statement: 11 years ago, I decided that if I could do something from the command line, I would. This was among the most important decisions in my career. This sent me on a journey, a Unix journey, in which understanding was one seemingly minor but important epiphany after another toward a more complete understanding of what the computer is actually doing. With the command line, I learned how to inspect a machine, how to converse with it, and ultimately, how to build my own environment to do anything -- including working from a remote machine as though it were right in front of me. --rduplain PS: Learn GNU Screen or tmux and use emacs or vim inside it.
Most applications I see really do fit on one box. More boxes, more problems. Load balancers are an important tool, but only when you have load. Not all load. Some load goes away with insightful optimizations to your code and to your configuration.
Measure.
Then scale.
