Comment Disneyland already does this (in a small way)... (Score 1) 357

Some of the rides at Disneyland have started taking advantage of this idea by moving the passengers along on a moving beltway (kind of like at the airport) next to the ride... So you board the ride without the ride having to slow down at all... e.g. the Buzz Lightyear ride does this and I recall that it worked pretty well.

Comment Re:Quad Core In a Tablet/Phone? (Score 2) 123

I can think of dozens of things that they are dying to use that power for: Pumping 4x the pixels for a high resolution display, doing processing related to speech recognition (even if the matching is done server side), running spotlight indexing on local content as you download it... (e.g. your email and docs from the cloud), playing HD video while doing all of the above, supporting a "mission control" style app switcher with live previews and spaces style switching, supporting airplay in the background while you are using the iPad for something else (maybe even someone else controlling it), games with really good physics simulations (which are dominating the app store and making apple millions) :), multi-way video chat compositing, and ten things only Steve Jobs has thought of...

Comment Re:dumb question (Score 1) 164

A real engineer can speak to this better, but there is a big difference between the "near field" where you are actually coupling magnetically/capacitatively with the source and radiation which transmits energy over an arbitrary distance. I believe if you are stealing power by putting a big coil next to a power line you are essentially making half of a transformer and directly drawing power through it... whereas if you are at a greater distance all you can do is intercept radiated energy, which is already gone as far as the sender is concerned.

Comment Don't understand how TPB domain survives... (Score 1) 219

With years of fighting around the ISPs, hosting, and blocking of TPB can someone tell me how it is that the domain name has not just been seized? Haven't other names been grabbed / taken down for more specious reasons?

I understand that taking the domain name would not stop any of this, I am just amazed that they haven't tried...

Comment The private key is accessible through software? (Score 1) 306

Does anyone know what was involved in "dumping ROMs"? I would have assumed that the private key was buried in the hardware and not directly accessible via software... From his description it sounds like it was just stored in ROM and software obfuscated. If that was the case it seems odd that it took six years for someone to find it...

Comment Re:Pardon my ignorance(and I don't want a holy war (Score 1) 169

Both Java and C/C++ are strongly typed languages, which give a lot of information to the compiler and (in the case of Java) runtime. The question here is how much optimization people can do on a loosely typed language like JavaScript... Apparently they can do quite a bit because JS today is screaming faster than a few years ago.

You would expect that, all things being equal, the languages with a runtime (including JavaScript) should beat out those without because they can do things that you can't do statically. People who religiously believe that Java couldn't beat C/C++ simply failed to understand what is going on... Both languages have about the same amount of info, both have a compiler, but one has a runtime that is also a compiler that can go on analyzing and optimizing as the program runs... Which one wins in the long run? Duh.

So the question then is whether JS having a runtime can allow it to work around the lack of type information in the code. Runtimes can do things like observe the type usage and "optomistic inlining" that in some cases may compensate for the loose types. But there may always be cases where there is a penalty for loose types.

Comment Anybody still using the Motorola 68HC11? (Score 1) 224

I remember scouring the suppliers to buy these years ago... collecting the "good ones" with more memory, etc.... saving them for various projects that I never got time for :)

20 years ago the idea of being able to build a little computer into random things around the house for $10 in parts was crazy cool... It's still cool, but less so :)

Comment Re:Same as always (Score 1) 680

First, let me point out that a 2TB (2000 GB) internal disk is only $79 now... So cost should not be the problem. Next, I agree. You have to keep it "live" and migrating with you and also have at least some offsite backup in case of disaster.

If you work exclusively on a laptop then get a NAS (network attached storage) device with two mirrored disks... Use an "old" disk or combination of smaller ones to form an off-site backup. In 3-5 years when you run out of space on your NAS just roll everything onto a new one and make the old one the new off-site backup...

Pile up the old disks in your parent's basement or someplace unchanging like that :)

Comment Re:No access controls? (Score 1) 314

So anyone who's ever worked at FB as an engineer will have likely downloaded copies of all their friends' / family's / ex-girlfriends' inboxes, chat history, etc.

It just struck me as funny that all of that sounds really ominous and important to somebody who's maybe 20 years old... and when you get a bit older, married, and have kids it all just sounds so stupid :) OMG, my chat logs!

I'm not trying to be a bastard... its seriously just making me laugh right now at all the dumb stuff I used to worry about :)

Comment No, they won't... stupid. (Score 1) 329

Just because they include another gesture to reach the home screen doesn't imply that they are going to remove the home button and I don't believe any credible source has suggested this... It's just a stupid extrapolation from the new gesture they've added.

The most important reason the home button will stay is just the obviousness... If you don't know what to do (and lots of both young and old people don't) they have a point of reference to get back to sanity... That button will not go away unless / until something equally obvious can take its place and a 5 fingered gesture certainly doesn't fill that role.

Comment Slow typing affects coding style and quality... (Score 1) 545

I have seen this repeatedly over the years... People who are slow typists or more generally are not proficient in using keyboard shortcuts or other features their editors / IDEs are more reluctant to certain kinds of changes to their code... i.e. small things like renaming, general cleanup, refactoring... They find it frustrating and so they make smaller changes with poorer results.

It may not be a big issue in general, but it obviously a hindrance to productivity and changes how someone things about the cost / benefit of making changes.

Comment Re:Cheap, good. It's called progress... (Score 1) 754

Not free now, but cheap and closer to free as time goes on. That is the story with all technology. Stability control operates on electronic braking, which is already in essentially all cars now. That is why I said it is essentially just mandating software (and a few accelerometers probably).

Adjusted for inflation, cars are not insanely more expensive than they were 50 or 100 years ago, but they are insanely better.
