Creating good UX is certainly an iterative process, but the millions-and-years claim is a bit dramatic. It is definitely possible to 'over-spend' on UX, for example Google Maps was nearly perfect 3 years ago, but is increasingly u

Against a well-prepared adversary, a vulnerability can only be exploited once -- a zero day. After disclosure, or evidence of an exploit in circulation, such vulnerabilities become useless towards the agency's mandate, whether or not y

Having offensive capabilities and actually utilizing such capabilities are two different things. You can acknowledge the need for the former alongside the dangers of the latter, just as you would with any standing military.

Others have said as much. Here is a quote from William Binney, another NSA whistleblower, on advice that he has for Snowden: > I would tell him to steer away from anything that isn't a public service — like talking about the ability

The only "problem" is the cute color scheme (each Ocsigen projects gets its own scheme), but so what. Believe me, you don't notice the colors when using these docs for Real Work. The content here is solid; complaining about a

Haven't used js_of_ocaml personally, but documentation for Ocsigen's other projects is excellent, such as lwt. Took a quick glance through the js_of_ocaml docs and they seem similarly comprehensive. Note this is API reference docu

Nobody is saying that humans are perfect drivers; that is a red herring. The question is whether driver-less technology is ready to subsume humans. Without critically thinking about the state of current technology and its limitations, we mi

Humans and robots have very different failure modes. The problem with robots is ensuring they gracefully recover from unexpected states, whether induced maliciously or not. Everybody on HN should understand the difficulty of writing correct

My ChromeOS machine is a thin client that's used for SSH, connecting to either a server somewhere, or a beefier computer at home, so I can work from the couch. Originally had crouton set up for some local dev (CLI tools only to save RA

Some video encoders already incorporate perceptual optimizations (eg, x264's psy-rd and psy-trellis) that "look" better but lead to objectively worse results with traditional image quality metrics. Audio codecs, however, have

Not so much on the device itself, but there is a lot of baggage around the iOS workflow, imposed by Apple. You have to pay Apple $99/year, set up provisioning profiles, and fiddle with code signing when doing deployment. It was a gigan

Regarding three tier caching between RAM/SDD/HDD: isn't this exactly what ZFS L2ARC is supposed to do? Relying on that seems closer to the Varnish philosophy of leaving as much to the underlying system as possible. Or would t

Jeffrey Scofield has a OCaml cross-compiler for iOS [1], and a number of of example apps are available, including ones using OpenGL ES. The bridges connecting OCaml to iOS UI components are incomplete, so you might have to do a bit of work

George R.R. Martin's first book, The Dying of the Light (published 1977), is set on a lone "travelling" planet whose interstellar course passes it through a multi-star system. The final stages of this traversal is the premise

What exactly would you replace SIP with? Hangouts? Skype? Another proprietary OTT solution? Please, no. Are you confusing SIP with the public switched telephone network? They are two very different things; SIP can be used to signal PSTN tra

Not disagreeing with you. Learning a new JavaScript API is much more accessible than waddling through the morass of VoIP standards. But ultimately, that's all WebRTC is -- an API specification with MTIs for media handling that are goin

There is a lot of hubaloo over WebRTC in the telecom space, because there's nothing else happening there. Traditional V/VoIP has been stagnant since people started doing video chat using large TVs a decade ago, calling it telepres

Yes, with premium video, a subscription based model is a necessity. Advertising alone is not an option. The mechanics of video subscriptions is an interesting discussion for another time, however it's not certain whether a completely a

The issue is not black and white. Why should Chrome implement Apple HLS, rather than Adobe HDS, Microsoft SmoothStreaming, or MPEG DASH, among other HTTP streaming formats? What about RTSP -- a protocol designed for streaming, which Andro

Safari is the only browser that implements HLS except recent Android. Chrome does support H.264 in HTML5.

I doubt VoLTE will make any practical difference in day-to-day usage, unless carriers allow customers to default to a custom SIP/IMS registrar -- which won't happen for a long time. Calls (signaling) are still routed through the c
