To Design or Not To Design? A Third Good Question

Following my earlier discussions of testing and defect fixing, I’ll complete the trilogy by discussing the role of design early in projects. Recall the context: projects that have validated a genuine need by haven’t validated an economic proposition. Because of the uncertainties of such a situation, iteration is inevitable. Piloting a project on the runway you will like have to try many experiments to find value customers will buy. Capital efficiency while iterating extends the lifespan of the project and increases its chances of success. The more experiments you can perform per dollar, the higher your expected return.

Review

In the sibling essays to this one I argued that the Extreme Programming principles of Test Until Bored and Defects Zero were perfectly appropriate to the cruise phase of a product, where the business driver is increasing profit by lowering cost. These principles also serve to prepare the software to act as a platform from which to

Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:

Instructions

CloudFlare is an awesome reverse cache proxy and CDN that provides DNS, free HTTPS (TLS) support, best-in-class performance settings (gzip, SDCH, HTTP/2, sane Cache-Control and E-Tag headers, etc.), minification, etc.

1. Make sure you have registered a domain name.
2. Sign up for CloudFlare and create an account for your domain.
3. In your domain registrar's admin panel, point the nameservers to CloudFlare's (refer to this awesome list of links for instructions for various registrars).
4. From the CloudFlare settings for that domain, enable HTTPS/SSL and set up a Page Rule to force HTTPS redirects. (If you want to get fancy, you can also enable automatic minification for text-based assets [HTML/CSS/JS/SVG/etc.], which is a pretty cool feature if you don't want already have a build step for minification.)
5. If you
