Well the DRM isn't actually a useful feature, but having a player that supports BD-J, when BD-J is used for some kinds of DRM, is useful insofar as it lets you view the DRM'd discs.

If the question is whether BD-J being part of Blu Ray has added any useful features to Blu Ray, then I think the answer is no.

American engineering tends to use US-customary units. Scientific research mostly uses metric, but engineering uses mostly US-customary, somewhat varying by field (e.g. medical devices tend to use metric).

Interestingly it's so ingrained into a lot of aspects of North American production that even Canada, which has switched to using metric for engineering, has a lot of parts specified in a way that obviously refers to customary units, with things strangely coming in multiples of 25.4mm, 0.454kg, and the like.

Indeed. The text is a nice, manipulative propaganda piece. While I don't know women in the game industry, I know several female engineers, in EE, CS and some other fields. Some of them are very attractive, some are more plain. (I don't mind either way, conversation is far more important than looks.) Now, from their comments, there is no specific discrimination against women in tech. Some think there may be a slight bias either way, but not anything significant. Of course, incompetent women get yelled at and derided just the same as incompetent men, but they though that was rightfully deserved. And the one thing that they universally find quite repulsive is women playing the "women card" to get ahead instead of demonstrating solid skills. Most of them have observed that happening.

My conclusion is that this is nothing but a part of an ongoing power-grab effort by styling women as victims and men as primitive cave-men.

They just send data to some server they own in clear and they know your last public IP. For spywork, that is enough. If laws are draconian enough, they are also sure to find _something_ when they kick down your door. Also, when you are not on US ground (warning: current state, this may change), they may also just drone-murder you and bypass any legality whatsoever.

What is certainly there is at least several JavaScript zero-days. JavaScript is complex to implement and easy to get wrong. As this is a commercial effort (as can be seen by its immorality and focus on profit), they will go after low-hanging fruit. The JavaScript engine is the most promising one.

And who said it would not affect other users too?

Israel's pre-1960 borders? The ones were the West Bank belonged to Jordan and Gaza belonged to Egypt?

If it brought a real chance at peace, I believe Israel would agree to that. But Jordan doesn't want the West Bank anymore. Egypt doesn't want Gaza. Israel's pre-1960 borders still would not create a country called Palestine.

Jordan and Egypt don't want to deal with the Palestinian problem anymore than Israel does.


MIT' Combines Carbon Foam and Graphite Flakes For Efficient Solar Steam Generati 96

Posted by timothy

rtoz (2530056) writes Researchers at MIT have developed a new spongelike material structure which can use 85% of incoming solar energy for converting water into steam. This spongelike structure has a layer of graphite flakes and an underlying carbon foam. This structure has many small pores. It can float on the water, and it will act as an insulator for preventing heat from escaping to the underlying liquid. As sunlight hits the structure, it creates a hotspot in the graphite layer, generating a pressure gradient that draws water up through the carbon foam. As water seeps into the graphite layer, the heat concentrated in the graphite turns the water into steam. This structure works much like a sponge. It is a significant improvement over recent approaches to solar-powered steam generation. And, this setup loses very little heat in the process, and can produce steam at relatively low solar intensity. If scaled up, this setup will not require complex, costly systems to highly concentrate sunlight.

What about the Stratosphere, which I wrote about previously? That didn't have a slide-out keyboard and so presumably wasn't serving a niche market. That was the one where the calendar app highlighted the wrong date as "today", because it (apparently) computed "today" based on GMT rather than the phone's current time zone.

If you're taking it as a given that the article statements were correct, my final statement was that we could improve existing phones by methodically testing them for idiotic problems (the Stupid Shit Index), so that consumers know how to find phones that have the least stupid shit wrong with them, the makers of those phones are rewarded, and the next iteration of phones has incrementally less stupid shit as a result. Since this is a big reward for relatively little effort, isn't it worth doing?
