I was mainly Java dev for 10+ years or so; I was a whiz at Eclipse. Then, one day, I forced myself to learn a Clojure. It just so happened the ecosystem mainly leveraged Emacs. And so, I forced myself to learn Emacs. It took a while - t

When you provision a card to Apple Pay by taking a photo of your card or entering the info manually, what happens next is that the iPhone makes a call to the card network (Visa/MC/Amex) to verify the card data (the card network wi

I started my Lisp journey seeking to learn Clojure too. I starting out with The Little Schemer[1]. I chose Scheme so that I could first wrap my head around the basic Lisp syntax, along with the recursive and functional thinking. To keep

Just being pedantic, but the more accurate term is: secure element. The SE has its own OS (JavaCard) and is usually directly wired to the NFC controller (no iOS in-between). http://globalplatform.org/mediaguideSE.asp

For what it's worth, I learned Emacs out of my desire to learn Clojure. It didn't take too long to develop the muscle memory (a few months of forcing myself to use it). Now, 6 or so years later, I use Emacs for essentially all a

It's both. Issuing banks can generate the payment tokens, but often, the networks can "stand-in" for the issuer, and generate the token for them on their behalf (the same way that networks can stand-in and do authorization o

No, Google Wallet doesn't. When performing a tap & pay at a merchant NFC terminal using Google Wallet with your Android phone (running 4.4+), your Google Wallet Mastercard card is the card-account actually being used vis-a-vis tra

With Apple Pay, your physical credit card number is NOT stored on the iPhone 6's secure element; instead, a token is (the token is effectively an alias to your credit card number; it looks like one too - is 16 digits, etc, so will work

Not only that, he had to design and create the MOLDS for the parts!

Nice comment. Very reminiscent of PG's "Beating the Averages" essay: http://www.paulgraham.com/avg.html Paul's essay was the catalyst that got me to (re-)discover Lisp for myself. Scheme was taught in

In Lectura 7A of SICP[1], Sussman opens the lecture by talking about how programs can be thought of as character-stream descriptions of a wiring-diagram for some kind of machine. And he actually goes on to talk about the notion of visual p

I agree. I would just add that there are lots of Busy Bobs, all of whom just want to consume your service, and don't want to have to bother with creating their own JSON/XML/EDN/etc marshaling/unmarshaling code, tra

This article echoes the same idea (instead of big singleton, view controllers should accept the data they require in their initializer (constructor)) and gives some reasons why to do it this way: http://www.hollance.com/2012

But it's obvious the world is already broken. It's not a stretch to infer by your post that you are implicitly passing some sort of judgement on the state of manufacturing jobs in these countries, and that is what folks are respo

Yes, but after 2 years and you've paid off the phone, that extra $30 or so comes off your bill (quite nice).With ATT, even after your contract expires, you're still paying that extra money for the subsidized phone.
