Callbacks are Pretty Okay
Among the many proposed solutions, one of them strikes me as particularly clean: "asynchronous wait" or "wait and defer". iced-coffee-script had this a while ago. Kal just debuted with an identical solution, only differing in syntax. Supposedly LiveScript supports this with "backcalls" .

Kal – a clean JavaScript alternative without callbacks
Kal is a highly readable, easy-to-use language that compiles to JavaScript. It's designed to be asynchronous and can run both on node.js and in the browser. Kal makes asynchronous programming easy and clean by allowing functions to pause and wait for I/O, replacing an awkward callback syntax with a clean, simple…

Edward Snowden and Gen Y: a sign of leaks to come?
(Before I begin: there are participants in the discourse who would say that we're supposed to natter on about Edward Snowden , and not the contents of his disclosures, because turning it into a personal issue rather than a political one is useful to the machineries of state. But the point I'm about to make here is…

Destructuring Assignment in ECMAScript 6
I have seen this question come up a few times, and unfortunately, people usually don't find an answer, give up, and don't test their source maps. However, testing source maps isn't too hard if you are using Node.js and the mozilla/source-map library. If you aren't using Node.js and the mozilla/source-map library, you…

The NSA is Commandeering the Internet
It turns out that the NSA’s domestic and world-wide surveillance apparatus is even more extensive than we thought. Bluntly: The government has commandeered the Internet. Most of the largest Internet companies provide information to the NSA, betraying their users. Some, as we’ve learned, fight and lose. Others…

40 Days Without Booze
Recently, as a “kick-in-the-butt” motivator, I promised myself that I would abstain from alcoholic beverages until I finished the first draft of a novel I’ve been working on. I had set a target date for completing the project (June 30th), with the idea that if I didn’t finish by that date, I’d stop drinking booze […]

Startup lessons
There are already very good lists of startup lessons written by really talented, experienced people (here and here). I’d like to add another one. I learned these lessons the hard way in the past four years. If you’re starting a company, I hope you have an easier path.

Hacking the OS X Kernel for Fun and Profiles
My last post described how user-level CPU profilers work, and specifically how Google’s pprof profiler gathers its CPU profiles with the help of the operating system. The specific feature needed from the operating system is the profiling timer provided by setitimer (2) and the SIGPROF signals that it delivers.

Investor Herd Dynamics
August 2013 The biggest component in most investors' opinion of you is the opinion of other investors. Which is of course a recipe for exponential growth. When one investor wants to invest in you, that makes other investors want to, which makes others want to, and so on. Sometimes inexperienced founders mistakenly…
