Look up Linux file permissions. To be very brief, you have to set the file to be executable before you can execute from the command line like you described. E.g. change the permission to allow the script to be executable: chmod +x test.py then you can run it like you were trying to: ./test.py...

I've heard it claimed before that brains could be quantum computers (I think it was on Through the Wormhole). Is there any evidence of this? I'm thinking about reading up on quantum computation, but don't know anything about quantum mechanics yet. I'm mostly interested in machine learning...

There would be insurmountable resistance to this idea. I imagine it would cause a sort of Crusade, as it would be seen as the "Mark of the Beast." Many Christians would assume they were living through the apocalypse, and whatever leader was pushing the idea would be the Anti-Christ, LOL. I live...

Depends. Languages that are normally interpreted (Python) and hybrid languages (Java) usually run code slower than languages that are compiled (Fortran). Theoretically, you could compile or interpret any language, so language does not really matter in terms of performance. Where language does...

To do that you'd first have to identify the sub-matrices that may contain letters, which may not be easy. Assuming that you could separate letters with high accuracy, I think you're solution would perform perform poorly on most captchas. Other problems are that the letters are usually skewed and...

Consider the reduce operation for example. Do all nodes send data directly to the root? Or is there some structure where a node will receive data from a few other nodes, perform a reduction, then pass the intermediate results to other nodes?

That's it, thanks.

I've never seen this notation before. What does the ellipsis right after the first summation mean: \begin{equation} \label{aixi_eq} a_t^* = \arg\max\limits_{a_t}\sum\limits_{o_t r_t} \dots \max\limits_{a_{t+m}}\sum\limits_{o_{t+m} r_{t+m}}[r_t + \dots + r_{t+m}]...

Wow, thanks for all these references. Never heard of EQ before, and it's all very interesting. But, EQ seems to measure total brain mass, and from what I understand, it's mostly just the cortex that's responsible for higher-level thoughts, and all that stuff in the middle takes care of all...

Dolphins have larger brains than humans. So, why aren't they smarter than humans... or, are they? Are those sneaky Dolphins playing dumb? j/k It's my (very limited) understanding that the cortex is responsible for the higher levels of what we think of as intelligence. So, what's different...

Sounds like a good fit for Processing: http://processing.org/ Here's an example of GoL in Processing: http://processing.org/learning/topics/conway.html

Although the OP seems to just want to know how to secure his computer, I'll offer my opinion for future reference. If you want to "hack" or "crack" in the sense of security related issues, you're probably going to want to focus on low-level programming languages, and really get a thorough...

Short answer: "Model" is a feature of MySQL Workbench, not really the database software itself. You use it to model out a database like you would on pen and paper. Once you've modeled a database, there's a menu option somewhere (I haven't used Workbench in a while :)) that automatically...

For backups of documents (this isn't exactly security related), I use SpiderOak. You set up watch folders, it keeps track of the changes, and uploads your files to their servers. It uses an encrypted connection, and all your files are encrypted on their servers (The SpiderOak team can't...

My web programming experience consists of PHP, and a little bit of Ruby on Rails. For PHP, Netbeans is great. For RoR, I used Aptana Studio, which was nice as well. Like jedishrfu said, C++ is rarely used in website design. Server-side code is usually written in scripting languages or Java...
