Fast

Rarely in software does anyone ask for “fast.” We ask for features, we ask for volume discounts, we ask for the next data integration. We never think to ask for fast.

AI is the technology that is going to revolutionize the way we work, the way we interact with the world, the way we learn, the way we socialize, and all…

Filing the corners off my MacBooks

I file the sharp corners off my MacBooks. People like to freak out about this, so I wanted to post it here to make sure that everyone who wants to freak out about it gets the opportunity to do so.

I got pwned by my cloud costs

I have been, and still remain, a massive proponent of "the cloud". I built Have I Been Pwned [https://haveibeenpwned.com/] (HIBP) as a cloud-first service that took advantage of modern cloud paradigms such as Azure Table Storage to massively drive down costs at crazy levels of performance I
