Programmers are the most optimistic bunch of people I have ever come across. Ask us how long something will take and chances are our estimates will be way off. It’s not because we hate you. It’s not because we didn’t know any better, either. We’re just very optimistic about everything.

Typography in 8 bits: System fonts

My love of typography originated in the 80's with the golden years of 8-bit home computing and their 8×8 pixel mono-spaced fonts on low-resolution displays.

The History of the Modern Graphics Processor

The evolution of the modern graphics processor begins with the introduction of the first 3D add-in cards in 1995, followed by the widespread adoption of the 32-bit operating systems and the affordable personal computer.

Is ASP.Net vNext The New Node.js

ASP.NET vNext has a pretty cool name. But what does it mean to the day-to-day .NET web developer? Let’s take a brief look.

The Internet in Real-Time

Did You Know? A common myth is that Skype's parent company, Microsoft (Nasdaq: MSFT), originated as a penny stock before turning into a successful, multi-billion dollar behemoth, when in reality it was never a penny stock.

What Does a Neural Network Actually Do?

There has been a lot of renewed interest lately in neural networks (NNs) due to their popularity as a model for deep learning architectures (there are non-NN based deep learning approaches based on sum-products networks and support vector machines with deep kernels, among others).

Poor man in the middle

This is a personal story not related to jPOS, but it’s somewhat related to payment networks and security, so I hope you enjoy it.

Everything Is Broken — The Message — Medium

Once upon a time, a friend of mine accidentally took over thousands of computers. He had found a vulnerability in a piece of software and started playing with it. In the process, he figured out how to get total administration access over a network.

NuGet Package of the Week: ImageProcessor - lightweight image manipulation in C#

I really enjoy image manipulation in code. Sure, resizing photos is fun in Photoshop, but there's something viscerally enjoyable when you change images with your own code. I've talked about image resizing libraries like ImageResizer before, but there's certainly room for more than one.
