This is actually quite fascinating (and part of my upcoming book...) Despite the obvious high/low-level language differentials, people have been managing multi-million-line C code-…

Oh it absolutely is, and I'm on your side. My point though, is that it's always a "secondary" or "tertiary" business concern... a point emboldened by the number and frequency of da…

I do think there's some value to pointing out the irony though; two men from two cultures that couldn't be more distinct, with titles that could be synonyms, using what is essentia…

Not exactly, I think it was a poor choice of words as I was referring to my build/deployment tooling. If I have an idea (e.g. a "ES2015 to ECMA6" converter), I'd look for a library…

I have two books in my queue actually, and this is one of them. There are parts of my content-property model I'm not ready to share, but most of it has been structured into a cohes…

Well, "startup" is a poor choice of words, but he actually has a half-decent idea. As someone who owns dozens of little "tool" sites (think less/scss converters, meme generators, J…

It's really interesting to see services like this emerge. In my opinion, the merchant processing/gateway revolution happened when providers (Stripe, Braintree, et al) started provi…

You may have misunderstood me there. Yes, Islam is a particularly violent religion -- if you have read the Koran, many of its concepts seem very incompatible with the idea of a fre…

It does if you play devil's advocate and follow the chain of reasoning. If god is great and non-believers are bad and "god" says it's righteous and just to punish the non-believers…
