Much of my work the past few years has been working with Amazon's seller-side e-commerce APIs, and it's truly infuriating how impenetrable their "support" systems are. It's ridicul…

I rode through a huge area filled with these sorts of walls somewhere wayyy down a dirt road in rural central Mexico, sorta near Zacatecas. It looked like it was once a vineyard, o…

disclaimer: i've only been doing this for a couple years...but it's gone pretty well. i've written this more like a story than direct advice, because i think all the twists and tur…

That's so cool that you were part of the founding team for a makerspace! I'm working on building something makerspace-y right now...If you're open to it, I'd love to ask you a coup…

Well, it's not programming-related, but here goes... I'm building a cooperative hands-on workspace in Brooklyn in an old warehouse. I have lots of interests that require space and …

I maintain a much, much smaller PHP library[0] (~1-2k downloads/month), and I've made a few thousand dollars in sponsorships, donations, and paid improvements to the library over t…

Many people who are excellent at something cite their mentors as a major reason for their skills and success. If you've had an impactful mentor of any kind (not just programming-re…

I built a PHP library[0] for Amazon's new Selling Partner API, because none of the existing libraries were feature-complete enough for the projects I was working on. To my surprise…

Silly question, but...is your megastick just a large-capacity USB stick?

Uranium can be extracted from seawater, and my understanding is that there's enough uranium in the oceans to last 10s (maybe 100s?) of thousands of years at current energy consumpt…

I think that if you consider storage, then you can in fact amortize panel power generation across day and night, because you need more panels during the day to create the extra pow…

I agree that it's not necessarily true that everyone can become world-class at their job, but I think most people have the intellectual capability to become really good, if expendi…

Cal Newport has a book that discusses this this called So Good They Can't Ignore You, which I found really interesting. His thesis is basically that the people who are most satisfi…

I fell for one of these offers on the first thing I made that got any traction -- it was a browser extension that solved an issue with a common photo hosting site, and I organicall…
