You've probably heard the claim that coding, or computer programming, is as crucial a skill in the 21st century as reading and math were in the previous century. I'll go one step further: Teaching a young person to code could be the single most life-changing skill you can give them. And it's not just a career-enhancer. Coding is about problem-solving, it's about creativity, and more importantly, it's about empowerment. Empowerment over computers, the devices that maintain our schedules, enable our communications, run our utilities, and improve our daily lives. read more

While hosting a quarterly town hall meeting with my team a few months ago, I announced that we had finally hired a new senior manager to lead a big portion of the group. This role had gone unfilled for a while, so I'd been temporarily filling it. After describing the new leader and reviewing the selection process, I asked if anybody had any questions or comments. There was just one, and it was something like: "So, now that you are hiring this new person, what are you going to do?" read more

Webpack is a robust and extensible tool that brings speed, parity between environments, and organized code to your application. It does its best work graphing a modular codebase, tying many graphed dependencies together into a few output files.

This article illustrates the methodology to offload the part of computations to GPU without refactoring the applications. The Crossroads/NERSC-9 Memory Bandwidth benchmark is used to showcase the offload of dense matrix multiplication (DGEMM) computations on GPU by linking (compile time) the newer version of CUDA-enabled ESSL (IBM Scientific Library). The use of CUDA-enabled ESSL gives approximately six times performance gain over CPU-only code.

Hackers at Def Con's voting machine village made quick work of showing just how vulnerable 'secure' voting machines really are.

In the first post of our series, we outlined three components of a modern front-end stack. In the second post, we untangled the challenge of package management with Yarn.
