Better Cache Busters (aka Asset Timestamps). Posted by Jonathan Kupferman. On Thursday, September 16, 2010. Now that we know something needs to be added to the URL, the question becomes what should we add? There are three properties that we are really interested in:. 1 The value should (only) change when the contents of the file changes. 2 The value should be consistent across different machines. 3 It should be fast to compute.

Peering In The Clouds. Posted by Jonathan Kupferman. On Tuesday, February 16, 2010. Here is what Wikipedia has to say about the benefits of peering. Peering involves two networks coming together to exchange traffic with each other freely, and for mutual benefit. This 'mutual benefit' is most often the motivation behind peering, which is often described solely by "reduced costs for transit services". Other less tangible motivations can include:. Increased routing control over your traffic.

Managing Talent: A Running Metaphor

Managing Talent: A Running Metaphor. Posted by Jonathan Kupferman. On Sunday, November 27, 2011. When I first joined the cross-country team in high school I naively thought that running was all the same, you just ran. Then came the first day we ran hills. It was then that I realized that running has a lot more technique and skills then were initially apparent. One of the most important things I learned was how run down hill. Is that some sort of weird surfer zen thing? November 28, 2011 at 4:07 PM.

Ship Code When It Is Ready

Ship Code When It Is Ready. Posted by Jonathan Kupferman. On Sunday, January 1, 2012. My previous jobs had what I consider a fairly standard month long release cycle. The first three weeks of the were spend writing code. On the fourth week the code was dropped to QA where they would hammer on it, find bugs, and have developers fix them. At the end of the fourth week the code shipped. Was someone integrating with my code going to break it? I’ll never forget that feeling. 8221; To which he responded &#8220...

Twitter is a bar and other Social Network metaphors. Posted by Jonathan Kupferman. On Wednesday, June 16, 2010. I have spoken with a few people recently about social networks and how they compare. In explaining it, I’ve settled on a few metaphors that most people seem to understand pretty intuitively. Here goes. Twitter is a bar. Facebook is a coffee shop. LinkedIn is a library. So where do you want to hang out? Links to this post. Twitter is a bar and other Social Network metaphor.

Eatability Testing: Why don’t more restaurants do it? Posted by Jonathan Kupferman. On Sunday, November 27, 2011. How many times has this happened to you, it is late on Sunday evening and you call one of your favorite restaurants for a little delivery. You pick your favorite item off the menu, place your order, and wait in anticipation. Thirty minutes and a cash exchange later and food is on your dinner table. You pop open the styrofoam container, grab a bite, and yuck, it’s cold. If you are serving some...

2011 PaaS Predictions: Winners and Losers. Posted by Jonathan Kupferman. On Saturday, December 25, 2010. Heroku’s $212 million dollar acquisition by Salesforce. I also suspect that we will see Heroku start getting a little more enterprisey in their offering over the next year. Unfortunately I don’t think they will see a lot of uptake since most enterprises move slower than molasses on a cold day. As I discussed in my previous blog post. Links to this post. Platform as a Service (PaaS) Fragmentation.

Web Application Caching Strategies: Generational caching. Posted by Jonathan Kupferman. On Sunday, June 5, 2011. This is the second in a two part series on caching strategies. The first post provided an introduction and described write-through caching. Here is some sample code for how this could be implemented (in psuedo-Python):. After implementing this strategy in multiple applications I want to point out a few things about how it works and its performance properties. In general I have found that u...
