F.lux and custom color temperatures for Mac OS X

There is something to be said about using computers before going to sleep, and the effects they have on how well we sleep at night.  The authors of the free software F.lux believe that one of the reasons for the sleep disruption after using a computer is the color temperature of the screen.

They postulate that computer screens are designed to feel like sunlight during the hours of the day, which is great, but they don't change how they look at night, which is not so great. They designed and implemented the F.lux software to warm up the screen as the sun goes down. And to make things easier, the software can automatically read the location of the computer, and adjust the warming schedule accordingly.

The software is free, and works on Windows, Mac, and the jailbroken iPads/iPhones. I have only tried it on the Mac, and while I cannot attest to any changes in my sleep patterns, I admit that the screen looks a lot more pleasing at night: warm and soft, unlike how it looked before.

Kindle Paperwhite

I have always been allergic to buying specialized electronic devices that do only one thing, such as the Kindle, the iPod, and fitness trackers. Why buy these when technology evolves so fast that a multi-purpose device such as the phone or a smart watch can eventually do the same thing, but with the convenience of updates that fix bugs and add functionality? So, I was shocked when this weekend I made an impulse buy and got the newest Kindle Paperwhite—a special purpose device for reading eBooks. I was walking past the Amazon store in the mall and saw that the newest Kindle Paperwhites were marked down by $40 for the holidays. The device looked good in the display, so I went in to look at it closely. The Paperwhite is small and light, with a 6” screen that is backlit and waterproof.   The text was crisp and readable, and in the ambient light, it felt like I am reading a printed book. I was sold and bought it on the spot. At home I have struggled to put it down. The bo...

A paper a day keeps the dr away: Dapper a Large-Scale Distributed Systems Tracing Infrastructure

Modern Internet scale applications are a challenge to monitor and diagnose. The applications are usually comprised of complex distributed systems that are built by multiple teams, sometimes using different languages and technologies. When one component fails or misbehaves, it becomes a nightmare to figure out what went wrong and where. Monitoring and tracing systems aim to make that problem a bit more tractable, and Dapper, a system by Google for large scale distributed systems tracing is one such system. The paper starts by setting the context for Dapper through the use of a real service: "universal search". In universal search, the user types in a query that gets federated to multiple search backends such as web search, image search, local search, video search, news search, as well as advertising systems to display ads. The results are then combined and presented back to the user. Thousands of machines could be involved in returning that result, and any poor p...

Mining the Social Web, by Mathew Russell, O'Reilly Media

"Mining the social web" is a book about how to access social data from the most popular social services today by using the services' public APIs, and analyzing the retrieved data to gain insights about it. The book uses the Python programming language to access and manipulate the data, and provides code snippets of common tasks within the book, as well as full iPython notebooks on Github. The book is written as documentation for the freely available iPython notebooks, with the documentation providing context and background for the code, as well as describing the algorithms used to mine the social data. The author tries to be as concise as possible, although he did not succeed in the first chapter, where the first three section were verbose, and relatively unnecessary,  describing what twitter is and why people use it as a microblogging platform. With that out of the way, the writing style improves as the book progresses, and is a mixture of code examples and step ...
