I'm not sure what you're getting at, either. The Casimir effect is real, absolutely. I think it was an exercise in one of my quantum field theory classes. In particular, the Casimir effect is something that you can compute entirely within the structure of existing physics, and it doesn't violate any conservation laws.

Now, if you suggest that I can somehow extract the Casimir energy without having put the same energy into the system first, I'll start arguing about violations of the laws of physics (in much the same way that I have above).
I admit that I haven’t! However, I think you’re talking about baking in a crappy solar oven, not baking in a solar oven in general. For example, http://www.solare-bruecke.org/infoartikel/Papers_%20from_SCI... describes a 3.4m² kilowatt prototype solar oven successfully used to cremate chunks of goat meat at temperatures of 800° to 900° in under an hour.

Larger solar ovens (usually known as “solar furnaces”) can reach 4000°, adequate not just for cooking or even cremation but also for firing terra-cotta, blowing glass, calcining lime, firing earthenware, making glass, firing porcelain, calcining portland cement, making borosilicate glass, casting aluminum, melting porcelain, purifying metals by zone melting, casting iron, smelting iron, casting steel, melting lime refractory, making quartz glass, casting basalt, boiling aluminum, vaporizing steel, vaporizing quartz, vaporizing lime refractory, melting tungsten, and sublimating graphite. Although people have been doing most of these with solar ovens for a while, especially the famous solar furnace at Odeillo, you can’t do all of these with Iron Age materials; apparently if you want to do anything useful with melted tungsten, you have to use Ta₄HfC₅ or similar.

Of course none of this works when it’s cloudy or dark, although molten-salt heat storage might be a usable solution to that even at a household scale.

The interesting question, and I have no idea what the answer is, is whether Silicon Valley will recover from what's been done to it.

There have always been douchebags everywhere, but it used to be something that one was ashamed of. If you funded someone like Evan Spiegel, you didn't talk about it. You just pretended that it didn't happen and called it a learning experience. Now, we have a culture that values material success at the expense of all else, isn't really about technology or progress, and views Sean Parker levels of douchebaggery as a positive trait.

The Bay Area used to be for misfits who chose to go off and do their own thing: live among the redwoods, play with circuits and computers, go mountain biking. Now it's full of self-marketers who create the impression that they do all of that stuff, while actually being unimaginative corporate drones even worse than the last generation's kind.

All of that said, Silicon Valley has a long history and it's not going to be ruined forever by a few bad years. If Silicon Valley gets back to a culture of invention, and if we fix the culture by regulating VCs a bit (a start would be to block the anti-competitive back-channelling and social proof checking; we couldn't eradicate all of it de facto but making it illegal would change behaviors enough to give us a chance at fixing the place) it could return to its old promise.

Another thing that Silicon Valley needs to do in order to save its character is fix the cost-of-living issue by crushing some NIMBYs. I think that the federal government needs to step in and crush every anti-development policy, unless there is a legitimate environmental issue.

I sincerely hope that the Valley does survive, because if you take the long view and look over the past 50 years instead of the past 5, you see that it has done more good than bad for the world.

Every time I hear about Servo, it mostly can be boiled down to:

B: We're not even remotely close to something really useful yet

I think that says more about how websites work, to be honest.

> Should have been implemented in Java :/

If you are looking for an open source Minecraft-compatible implementation in Java, I humbly suggest (shameless plug) checking out https://github.com/GlowstonePlusPlus/GlowstonePlusPlus. Glowstone++ like TrueCraft currently only implements the server portion, and it has some differences such as targeting 1.8.4 compatibility not 1.7.3 beta, but being implemented in Java has some significant benefits.

For those not aware there is a huge ecosystem of additions available for Minecraft written in Java. This includes thousands of "Bukkit plugins" available from http://dev.bukkit.org/categories/, Spigot plugins from http://www.spigotmc.org/resources/, and now an emerging community of Sponge plugins from https://forums.spongepowered.org/c/plugins/plugin-releases. Writing Minecraft-compatible software in Java has the advantage of being able to potentially support these plugins. Glowstone++ in fact implements much of the Bukkit API and Spigot API, as well as (currently a small subset of) the Sponge API through a bridge. Based on the original Glowstone server, Glowstone++ is completely open source, yet it ties into the existing "Minecraft" plugin development ecosystem.

Java has some disadvantages of course as well, so it's good to see alternative implementations in other languages (not only C# TrueCraft, but C++ MC-Server, Rust Hematite, JavaScript PrismarineJS, etc). The more choice the better =)
For the longest time, everyone thought that the earth was flat as well until this heretic said, nope it is flat.

Challenging group think and being skeptical is part of being a proper scientist. Perhaps they end up learning something entirely new from all of this.

Yes, it would be more precise if I had prepended "local" every time I said "conservation of momentum" above. With that clarification, I'm happy to stand by what I've said.
Yes, and it's exactly what's happening. There's no market inefficiency here. During the few days when IPOs are available, the overnight interbank interest rates usually increase significantly compared to other days. On average you can expect to make about 10% p.a. almost-risk-free from IPOs, similar to gearing A-grade corporate bonds.
I know it's in Nightly, but wasn't it in Nightly 3-5 months ago, too? Shouldn't it have moved to the "next" development version by now, like Aurora or whichever is the next "more stable" one, if Firefox follows a 6-weeks development cycle?
+1 to first upgrading your home. I live in the Bay Area but in a tightly sealed late 90's 1600 sqft house. No A/C. Recently upgraded our furnace and water heater to high efficiency models, and now spend about $400/year electricity, $400/yr for gas. Even accounting for the warmer winter this year, the gas savings was about 14%. There are pretty good incentives in the Bay Area for home energy upgrades if you do multiple at once: https://www.bayareaenergyupgrade.org/program-overview
Videotape - Austin, TX or Houston, TX

We have an incredible team - each of us with backgrounds of success in a variety of areas. We're aiming very high with this app, with a long-term marketing strategy, plans for release of features and monetization strategy.

Joining the team now, you would have the opportunity to make your mark on the product and build awesome stuff.

Contact us at info@videotape.co with links to your past projects and a little about yourself. Thanks!
I'm really curious how Servo (and Electrolysis which I know is un-related) are planning to handle the GPU. Most GL drivers if not all of them are not multi-thread happy.

Are they implementing an internal command buffer like Chrome or is there some other solution that allows multiple threads and/or multiple processes to all output content to the same window?
Mr. Andreessen and his partners have invested so much

The stack of web technologies is staggeringly enormous. It may not feel like it just scanning over a simple HTML page, but it is, and there's a lot of invisible-yet-critical stuff like proper same-origin policy enforcement. The miracle is not that it takes Servo a while to be created, it's that this stack works at all, and that they're even trying!
From http://www.bloomberg.com/news/articles/2015-04-07/u-s-dot-co...

The use of margin debt to trade mainland shares has climbed to all-time highs, while investors are opening stock accounts at a record pace. More than two-thirds of new investors have never attended or graduated from high school, according to a survey by China’s Southwestern University of Finance and Economics.
The Constitution says nothing about borders and soil for the limits on the government's activity. It enumerates what the government is allowed to do, no borders no soil. Non-enforcement doesn't make it law.
Please if you are offering internships, write out intern in all caps or else searching the page becomes very difficult. These posts need to become standardized or else finding relevant posts takes three times as long, because posters will use the words "internet" and "internal" et al very often.
I agree with this view of most intellectual "property", but it doesn't apply here. In the case of finance, trade secrets absolutely are rivalrous.

Strategies have limited capacities, so if anyone else is trading using your strategy you're going to be making less money. This is exacerbated by how markets are largely anonymous and distributed: nobody is trading with a given firm specifically, so somebody using your long-maintained strategy doesn't face any disadvantages against you.

Moreover, being secret is the only protection strategies can meaningfully have. Copyright can't cover the strategy itself, just the code to implement it, and patents by definition require divulging how it works. And even if you could somehow enforce a patent on a trading strategy, other people would still be able to trade against it, making the whole idea a non-starter.

At the same time I still don't think prison is a good answer to this sort of crime—but I don't think it's a good answer to car theft or most other sorts of crime either. But that's a function of deep issues I have with the justice system, a story best left for another time.

While I support this idea and have believed for a long time now that a critical mass of the sysadmins, engineers, et al. that keep the world turning have more power than most politicians if they could just ignore the usual arguments for a while and organize. Look at the panic over Occupy; if the money stops flowing because nobody is there to keep the infrastructure working, I expect mass hysteria.

This kind of plan is dangerous - in this political climate, there is a good chance such a strike would be labeled a terror plot, and the people with guns will be sent in to do what they usually do.

Another consideration: similar to how "total information awareness" wasn't really canceled - it just got a new name and distributed into several departments - COINTELPRO wasn't really canceled either. Remember that any leader or central organizer is a target. Decentralize everything.
This is why when I vote, I put a lot of weight on those who advocate campaign reform and voting reform.
Keep in mind he didn't vet the ACTUAL post before I pushed it live.

In reading it back, I wouldn't say he was enthusiastically pushing it or anything:

"I think you guys have your minds made up. The reality is the risk is probably low. Truth is an absolute defense to defamation. It's unlikely a couple Russians would try to sue you, but you never know. My boring attorney answer is try not to go too far to minimize any risk. Stick to the verifiable facts."

Are they planning on implementing a JavaScript engine in Servo as well?
Doing it, and doing it fast enough to guide a missile at > mach 2 are different things entirely. The rate that you have to constantly be calculating the spin (if any) and the vector and speed is incredible. OTS 5-10hz refresh will not cut it.

That said OTC stuff is so dangerous now that I think we should roll back the laws to allow home lab/hackerspace science to evolve. I would love to launch a rocket from weather balloons, but it would stand little chance of getting anywhere with OTS GPS gear.
You'd think, but that depends on how many times you can sell the same battery. As others have said, it's plausible that this is a way for Tesla to make use of used car batteries.
