No, the numbers work out. I think you missed the per square mile aspect of the number you are quoting

With these assumptions, figuring out how much solar energy hits the entire planet is relatively simple. 12.2 trillion watt-hours converts to 12,211 gigawatt-hours, and based on 8,760 hours per year, and 197 million square miles of earth’s surface (including the oceans), the earth receives about 274 million gigawatt-years of solar energy, which translates to an astonishing 8.2 million “quads” of Btu energy per year.

Dubious. A statistical significance to a pattern is merely an indicator of an actual relationship.

Amen. Especially if you took advantage of the $100 for 100 issues offer LJ made at the time of the 100th issue.

My set up has one monitor in potrait and one in landscape mode. Won't work with compiz that Unity is built on. It worked in 10.10 with Xinerama & RandR. Hardly an improvement.

I am getting used the slicker look of Unity, though. Too bad it has to go.

Coder Accuses IBM of Patenting His Work 249

ttsiod writes "Back in 2001, I coded HeapCheck, a GPL library for Windows (inspired by ElectricFence) that detected invalid read/write accesses on any heap allocations at runtime — thus greatly helping my debugging sessions. I published it on my site, and got a few users who were kind enough to thank me — a Serbian programmer even sent me $250 as a thank you (I still have his mails). After a few years, Microsoft included very similar technology in the operating system itself, calling it PageHeap. I had more or less forgotten this stuff, since for the last 7 years I've been coding for UNIX/Linux, where valgrind superseded Efence/dmalloc/etc. Imagine my surprise when yesterday, Googling for references to my site, I found out that the technology I implemented, of runtime detection of invalid heap accesses, has been patented in the States, and to add insult to injury, even mentions my site (via a non-working link to an old version of my page) in the patent references! After the necessary 'WTFs' and 'bloody hells' I thought this merits (a) a Slashdotting, and (b) a set of honest questions: what should I do about this? I am not an American citizen, but the 'inventors' of this technology (see their names in the top of the patent) have apparently succeeded in passing this ludicrous patent in the States. If my code doesn't count as prior art, Bruce Perens's Efence (which I clearly state my code was inspired from) is at least 12 years prior! Suggestions/cursing patent trolls most welcome."

Interesting Computer Science Jobs? 352

mattskent writes "I'm currently a junior in college working towards my Bachelor's degree in Computer Science. As such, I'm starting to look pretty seriously at jobs in the IT/Computer Science field. I've spent plenty of time working entry-level IT jobs doing various kinds of help desk type work, and so most of the exposure I've had to the field is related to support of other people's computers. I enjoy helping other people out, but I'd rather not be plugging things in and restarting computers the rest of my life. Although the possibility is growing on me, I don't think I would particularly love to write code all day for a living either. What are some interesting jobs that you've had or heard of that I could look into fresh out of college with a Computer Science degree?"

Programming .NET 3.5 224

Posted by samzenpus on Monday November 03, 2008 @01:00PM

lamaditx writes "The world of the .NET framework is taken to the next level by the release of .NET 3.5. The intended audience of this book are experienced .NET programmers. There are no sections that tell you details about C#, SQL servers or anything like that. I don't recommend this book if you never worked on a .NET project and don't know how to set up a SQL database. You should be aware that the code is written in C#. You might use one of the software code converters if you prefer Visual Basic instead. I think the code is still readable even if you do not know C#. I appreciate the fact that the authors decided to use one language only because it keeps the book smaller. The authors assume you are using Visual Studio 2008. You don't necessarily need to update to 2008 if you are working with an older edition because you can use the free Express Edition to get started." Keep reading for the rest of Adrian's review.

Chrome has crashed several time on Windows 2003 x64 already. Just clicking on Options crashes the browser. Watched the videos on the Chrome site and tried the new features. When I tried to Bookmark the page, the browser crashed again. Having individual threads per tab does not help since the process crashes so all tabs and windows go.

The speed is decent but it's a long ways from a reliable everyday browser.

Military Robots to Gain Advanced Sight 71

Posted by Soulskill on Sunday January 27, 2008 @09:58AM from the stay-on-target dept.

coondoggie brings us a NetworkWorld report discussing iRobot's plans to include Laser Radar technology in their military robots. Quoting: "Specifically the robot-maker is licensing Advanced Scientific Concepts' 3-D flash Ladar which uses laser beams to scan and process targets. The system has the ability to create a virtual 3D picture of an entire area. IRobot ... believes the technology will provide new navigation and mapping capabilities for future generations of robots and unmanned ground vehicles and pave the way for autonomous vehicles to lead convoys into dangerous territory, search contaminated buildings for casualties, or enable bomb squads to safely investigate suspicious objects."
