004 JSJ Backbone.js with Jeremy Ashkenas

You are looking at pictures of a house that Simon Dale built for his family in Wales. It was built by him and his father in law with help from passers by and visiting friends. 4 months after starting they were moved in and cosy. He estimate 1000-1500 man hours and $5000 put in to this point. Not really so much in house buying terms (roughly £60/sq m excluding labour).

Hack on some side projects in your spare time, and host them at GitHub. If anything, this is the most important thing you can do. At least 80% of the emails I get from recruiters start with, “I saw your [X] project on Github, and…”

“Backbone Directory” is a sample application built using Backbone.js and Twitter Bootstrap. The application is an Employee Directory that allows you to look for employees by name, view the details of an employee, and navigate up and down the Org Chart by clicking the employee’s manager or any of his/her direct reports.

With over 15 billion page views a month Tumblr has become an insanely popular blogging platform. Users may like Tumblr for its simplicity, its beauty, its strong focus on user experience, or its friendly and engaged community, but like it they do.

Here are some miscellaneous other things I learned during my visit today:

• Defkalion has 27 people presently involved in their headquarters (where I visited) and their lab.
• Their lab is located elsewhere.
• Their primary product is “heat”. Their business model is arranged around that. Others can figure out how to put that heat to good use.
• The reaction chambers are able to go as high as 900 degrees Celcius stably.
• The reaction begins at around 450 ºC.
• Nickel melts at 1453 ºC.
• They will used oil to transfer the heat from the reaction chamber to where it can be used.

The transmission strategy is that we send the first part of the codeword. If it doesn’t succeed, we send the second part, and so on. We don’t repeat transmissions: We always send the next part rather than resending the same part again. Because when you marry the first part, which was too noisy to decode, with the second and any subsequent parts, they together constitute a new, good encoding of the message for a higher level of noise.

Researchers at the University of Tokyo’s Institute for the Physics and Mathematics of the Universe (IPMU) and Nagoya University used large-scale computer simulations and recent observational data of gravitational lensing to reveal how dark matter is distributed around galaxies.

The notifications button will only appear if a valid push token has been registered with Socialize using [Socialize registerDeviceToken:]. This means the buttons will never show on the iOS simulator.

If you find you have problems with the Action Bar Automatic Layout, and you would like to disable the auto layout feature completely, you can do so. The following example disables autolayout and manually places the Action Bar at (0,400).

Quantum theory is perhaps the prime example of the infinitely esoteric becoming the profoundly useful. Esoteric, because it describes a world in which a particle really can be in several places at once and moves from one place to another by exploring the entire Universe simultaneously. Useful, because understanding the behaviour of the smallest building blocks of the universe underpins our understanding of everything else.
