Comment Re:If only.. (Score 1) 176

There was some way to have a remote... Say attached to the wall, which would allow you to 'touch' it to have the lights turn on and off, or even possibly dim. One can dream..

Exactly. The headline should have read "LG and Samsung follow Philips in adding pointless expensive gimmicks to lightbulbs in order to part consumers from their money".

Comment Re:"hacking charisma" (Score 1) 242

Somebody needs to teach how to resist "charisma".

Otherwise known as "critical thinking".

I'm assuming from your comment that you've probably never dealt with any sociopaths/psychopaths (technically, people with ASPD, antisocial personality disorder) or similar disorders like NPD before, because if you had you'd realise that critical thinking isn't going to help you. Firstly, in order to apply critical thinking you need to know that you're being manipulated, which you'll generally only realise that once it's too late. Secondly, until you've actually experienced what an ASPD person is capable of, you'll have no idea of the near-superhuman capabilities of these people to deceive and manipulate. The literature is full of stories of trained psychologists interviewing psychopaths who they know have killed a dozen children and eaten their livers, and coming away thinking what a charming person they've just dealt with. One somewhat nasty (but highly educational) trick that gets played on psych students is sending them into prisons to assess psychopaths. They invariably report them to be charming, friendly, and the sort of person they'd want to have around for dinner. In some cases even after they've read the reports of them keeping the various body parts in bags in the basement.

If you're targeted by someone with NPD/ASPD, you won't realise it until it's too late.

The frequency of a true MITM - one defined above where someone has the ability to control an intermediate node at low level and take central position - is so low as to be difficult to measure.

This is about as dumb of an argument against SSL as I can imagine. True MITMs are reasonably rare in large part because of SSL.

Comment Re:GPS? Are you kidding? (Score 3, Insightful) 373

The GPS code I've seen was horrible and I worked for one of the major GPS players for several years. Originally written in FORTRAN and later automatically converted to C. Utter crap basically. The mathematics behind GPS is really interesting and quite involved. The implementations are crap.

Saved me from writing the same thing. The GPS code I've seen, written by engineers and not programmers, was an incredibly hacked-together, barely-functional set of kludges to implement a lot of very elegant mathematics.

For another example of a well written large project, try gcc.

Another example that's at least as elegant as gcc is OpenSSL.

Comment Re:Snowden's an expert? (Score 2) 116

Wait a second, what on earth is he speaking at SXSW for? Is he now considered an expert on national security?

I don't know about national security, but he's shown himself time and again to be a very astute observer. It's the same with Bruce Schneier, he doesn't have a PhD in cryptography but people still listen to him because he's damn good at picking out the relevant bits and communicating them effectively to the masses.

Comment Re:digital utopianism (Score 1) 33

The idea that you can just throw tech at education problems is so common its got a name: 'digital utopianism'.

Beat me to it. The answer to the series of questions in the summary is "none of the above", instead of fancy gadgets we need a better pupil-to-teacher ratio, the ability for school boards to fire incompetent teachers, better support for teachers from parents (rather than treating them as glorified daycare nannies), and so on. Playing with gadgets is, at best, a distraction from addressing the real problems.

Comment Re:Why aren't we using PNG? (Score 1) 155

While JPEG 2000 has slightly better compression quality (less visible artifacts) at the same file sizes itâ(TM)s decode performance is substantially slower than JPEG XR (the same is true for encode performance, but decode is much more important).

How much of this is due to hardware support for core JPEG operations in GPUs and (to a lesser extent) CPUs? If wavelet-based JPEG took off, would it just be a matter of time before hardware vendors added explicit support for it to their instruction sets, at which point the speed difference would vanish?
