Still, I'd like to stress that picking the right language for your task can greatly reduce problem complexity.

For instance, algorithms are much more compact and easier to understand using a functional programming language. E.g. compare quicksort in Haskell and C - see http://www.haskell.org/haskellwiki/Introduction.

Complex concurrent programs remains challenging even with an excellent (IMO) concurrency library like the one in Java 1.5+. But switch to Erlang, and you'd find many concurrency patterns are expressed more naturally.

According to the article Slashdot uses an HTTP cache called Varnish, which uses the B-heap. Can any /. ed/admin comment on how effective it is?

Also, this idea seems similar to the locality optimizations proposed in algorithms like merge sort http://en.wikipedia.org/wiki/Merge_sort#Optimizing_merge_sort.

Indeed! Identifying what proxies (http://en.wikipedia.org/wiki/Proxy_%28statistics%29) to use is one of the trickier aspects in the soft sciences and statistics. If you read the Economist, you'd see proxies for just about everything (e.g. http://www.economist.com/markets/bigmac/), and a lot of research is required just to show what a given proxy measures.

I disagree as it depends on what you're teaching. Concepts like recursion and algorithms are best taught with functional languages. E.g. quicksort is a lot shorter and easier to understand in Haskell than in C - see http://www.haskell.org/haskellwiki/Introduction.

We generally agree that you need to pick the right language for a given task - the task of teaching various computer science concepts is no different. Also, a good curriculum should impart students with the ability to pick the right language for a given task too.

If you're interested in pursuing a computer science degree at university, you might be better off without a background in a imperative/procedural language. Many students who knew C/Pascal seemed to have a tougher time grasping functional languages than those who didn't know anything at all.

As you already suggested what you need to do is you need to separate the core engine and game content.

I agree that content development is hard to open source and seem best developed by an individual or a small group.

The successful open source projects you mention all have a plugin/module system. Ensure the game engine supports a good scripting language for content creation, and plugin system that can modify any aspect of the game, and I expect it will do well in the open source world. Your game in effect should just be a plugin/module to your engine.

You want a game engine that is able to foster development of plugins that can completely change the game's underlying mechanics (e.g. Oblivion), as well as plugins/modules that can tell rich and complex story lines (e.g. Neverwinter Nights).

Getting a bit off topic here, but you raise an interesting issue.

I bet that the frequency of certain searches can predict whether a company stock will increase or decrease, e.g. lots of searches for " problems" is a precursor to that company stock crashing.

I wonder what policies are in place regarding usage of such aggregate information within Google (or other search companies).

Indeed, and there's actual research supporting usage of the Wii Balance board for physiotherapy. Research was conducted by the University of Melbourne, which the Australian doctor probably read about and decided to recommend to his patient.

Although the H.264 licensing terms appear reasonable, I still prefer a free option.

Right!

Market Capitalization = Share Price x Number of Shares in Market

Obviously, Oracle has a lot more shares in the market than Red Hat. Over time, companies can also do a stock split, e.g. halve the share price, but double the number of shares; or a reverse split where price doubles but shares are halved - either way, market cap remains the same.

I take white hat to mean Good, i.e. you're not using the exploit for personal gain.

You're Lawful Good if you're working on behalf of some legal authority. Chaotic Good if you're exposing it to shame/antagonize the companies. Neutral Good if just out of your own personal reasons.
