The Idea Factory

This book is a history of the Bell Labs run by AT&T for much of the 20th century. These are the labs which produced many of the things I use day to day — Unix and the C programming language for example, although this book focuses on other people present at the lab, and a bit earlier than the Unix people. Unix, a history and a memoir for example is set in the same location but later in time.

The definitive history of America’s greatest incubator of innovation and the birthplace of some of the 20th century’s most influential technologies “Filled with colorful characters and inspiring lessons . . . The Idea Factory explores one of the most critical issues of our time: What causes innovation?” —Walter Isaacson, The New York Times Book Review “Compelling . . . Gertner's book offers fascinating evidence for those seeking to understand how a society should best invest its research resources.” —The Wall Street Journal From its beginnings in the 1920s until its demise in the 1980s, Bell Labs-officially, the research and development wing of AT&T-was the biggest, and arguably the best, laboratory for new ideas in the world. From the transistor to the laser, from digital communications to cellular telephony, it's hard to find an aspect of modern life that hasn't been touched by Bell Labs. In The Idea Factory, Jon Gertner traces the origins of some of the twentieth century's most important inventions and delivers a riveting and heretofore untold chapter of American history. At its heart this is a story about the life and work of a small group of brilliant and eccentric men-Mervin Kelly, Bill Shockley, Claude Shannon, John Pierce, and Bill Baker-who spent their careers at Bell Labs. Today, when the drive to invent has become a mantra, Bell Labs offers us a way to enrich our understanding of the challenges and solutions to technological innovation. Here, after all, was where the foundational ideas on the management of innovation were born.

Turnover of Companies in OpenStack: Prevalence and Rationale

  • Post author:
  • Post category:OpenStack

This paper examines the withdrawal behaviour of corporate contributors to OpenStack, which seems particularly relevant given most contributions in OpenStack are corporately supported, and corporate engagement is declining over time. Its also directly relevant to my own experiences contributing to the project, so seemed like a thing I should read. One interesting aspect of the study is how they define withdrawal from contributions. For each company, they calculate an individual frequency of contribution, and then use that to determine if the company is still making contributions. That is, of a company only ever contributed once a year, we must wait at least a year to know that they have indeed stopped contributing. The paper finds that in more recent OpenStack releases, more companies are leaving contributions than joining. The authors assert that in general engaged developers are now less experienced than previously, which presents risks in terms of developer effectiveness as well as code quality. However, the paper does note that companies with smaller contributions are more likely to disengage than "sustaining companies", however that's largely because there are a huge number of companies contributing only one developer who makes a small number of commits. Unsurprisingly, the paper notes that…

On-demand Container Loading in AWS Lambda

My team at work now has a daily personal learning time called “egg time” — its a slightly silly story involving a manager who was good at taking some time to learn things each day, and an egg shaped chair.

Today I decided that I should read this paper about container image loading in AWS lambda, as recommended by Robert Collins on LinkedIn. The paper details the work they had to do to transition from all Lambda functions being packaged as relatively small zip files (250mb), to relatively large Docker containers (10gb+) while maintaining their aggressive target cold-start time of 50ms.

The Accidental Time Machine

Joe Haldeman does good work, and in general I have really liked his books. They're easy to read, fun, and interesting. Better than that, they're all quite different in the topics they cover, so he's not in a rut. The only exceptions have been There Is No Darkness, which wasn't very good and Forever Free, which I thought was lazily plotted. This book is no exception to the rule, and I really enjoyed it. One theme to Joe's work that I am noticing is that the "sex scenes" are always anti-climatic, which is interesting to note. I'd like to have heard more about the One Year War, but there is scope for that to be another separate book. I don't think this book suffers from the lack of coverage, and its mostly tangentially interesting because I'd like to see how a society transforms itself in that way.

If you're an ACM member, or read ACM transactions on computer systems, or have a corporate membership to the ACM portal, then you really should checkout Inferring Internet denial-of-service activity. It's a surprisingly simple method of determining how common denial of service attacks really are on the Internet. Like all good ideas, it's also really obvious once it's been pointed out. @article{1132027, author = {David Moore and Colleen Shannon and Douglas J. Brown and Geoffrey M. Voelker and Stefan Savage}, title = {Inferring Internet denial-of-service activity}, journal = {ACM Trans. Comput. Syst.}, volume = {24}, number = {2}, year = {2006}, issn = {0734-2071}, pages = {115--139}, doi = {http://doi.acm.org/10.1145/1132026.1132027}, publisher = {ACM Press}, address = {New York, NY, USA}, }
