- Update on indie.vc — We’ve worked with the team at Cooley to create an investment instrument that has elements of both debt and equity. Debt in that we will not be purchasing equity initially, but, unlike debt, there is no maturity date, no collateralization of assets and no recourse if it’s never paid back. The equity element will only become a factor if the participating company chooses to raise a round of financing or sell out to an acquiring company. We don’t have a clever acronym or name for this instrument yet, but I’m sure we’ll come up with something great.

- DARPA’S Haptix Project — The goal of the HAPTIX program is to provide amputees with prosthetic limb systems that feel and function like natural limbs, and to develop next-generation sensorimotor interfaces to drive and receive rich sensory content from these limbs. Today it’s prosthetic limbs for amputees, but within five years it’ll be augmented ad-driven realities for virtual currency ambient social recommendations.
What is Hack and what does it mean for the future of PHP?
Facebook recently released Hack, a new programming language that looks and acts like PHP. Underneath the hood, however, are a ton of features like static typing, generics, native collections, and many more features for which PHP developers have long been asking. Syntax aside, Hack is not PHP. Hack runs only on Facebook’s HipHop virtual machine (HHVM), a competitor to the traditional PHP Zend Engine.
Why did Facebook build Hack?
Much of Facebook’s internal code is first written with PHP. Facebook can onboard new developers quickly with PHP because the language is notoriously easy to learn and use. Granted, much of Facebook’s PHP code is likely converted to a C derivative before being pushed into production. The point is Facebook depends strongly on the PHP language to attract new talent and increase developer efficiency.
Unfortunately, PHP may not perform as well as possible at Facebook’s scale. PHP is a loosely typed language and type-related errors may not be recognized until runtime. This means Facebook must write more tests early to enforce type checking, or spend more time refactoring runtime errors after launch. To solve this problem, Facebook added strict typing and runtime-enforcement of return types to Hack. Strict typing nullifies the need for a lot of type-related unit tests and encourages developers to catch type-related errors sooner in the development process.
Instantaneous Type Checking
To make the development process and error-catching process even easier, Facebook includes a type-checking server with its HHVM engine. This server runs locally and monitors Hack code as it is written. Developers’ code editors and IDEs can use this type-checking server to immediately report syntax or type-related errors during code development.

Android Malware Numbers, Open Networking Hardware, Winning with Data, and DIY Pollution Sensor
- Android Malware Numbers — (Quartz) less than an estimated 0.001% of app installations on Android are able to evade the system’s multi-layered defenses and cause harm to users, based on Google’s analysis of 1.5B downloads and installs.
- Facebook Operations Chief Reveals Open Networking Plan — long interview about OCP’s network project. The specification that we are working on is essentially a switch that behaves like compute. It starts up, it has a BIOS environment to do its diagnostics and testing, and then it will look for an executable and go find an operating system. You point it to an operating system and that tells it how it will behave and what it is going to run. In that model, you can run traditional network operating systems, or you can run Linux-style implementations, you can run OpenFlow if you want. And on top of that, you can build your protocol sets and applications.
