• Who are the most important people in open-source software? [closed]

  - by poseid

  I am reading a book by Malcolm Gladwell on the circumstances of successful careers. The book argues that Bill Gates, Steve Jobs, Bill Joy and more succesful computer pioneers were born between 1950-1955, and did absolve around 10000 hours of practice before microcomputers became widely available in the 1970s and their fairy tale success story begins. As we are in the age of web 2.0 with new forms of databases and persuasive access to information, who are in your opinion the most succesful computer programmers or scientists of our times, when were they born and to which technologies they had access?

• Python sock.listen(...)

  - by Ian

  All the examples I've seen of sock.listen(5) in the python documentation suggest I should set the max backlog number to be 5. This is causing a problem for my app since I'm expecting some very high volume (many concurrent connections). I set it to 200 and haven't seen any problems on my system, but was wondering how high I can set it before it causes problems.. Anyone know?

• Is marshaling/ serialization in PHP as simple as serialize($var) ?

  - by Ygam

  here's a definition of marshaling from Wikipedia: In computer science, marshalling (similar to serialization) is the process of transforming the memory representation of an object to a data format suitable for storage or transmission. It is typically used when data must be moved between different parts of a computer program or from one program to another. I have always done data serialization in php via its serialize function, usually on objects or arrays. But how is wikipedia's definition of marshaling/serialization takes place in this serizalize() function?

• Floating point precision and physics calculations

  - by Vee

  The gravity Vector2 in my physics world is (0; 0.1). The number 0.1 is known to be problematic, since "it cannot be represented exactly, but is approximately 1.10011001100110011001101 × 2-4". Having this value for the gravity gives me problems with collisions and creates quite nasty bugs. Changing the value to 0.11 solves these problems. Is there a more elegant solution that doesn't require changing the value at all?

• Port forwarding in C#/software possible? Isn't it only managed by the router?

  - by Rudi

  Isn't port forwarding managed by the router? Like, I've googled up some software applications that seem to port forward with great success, but it technically seems to be impossible. The packet must first go to the router. The router must forward it to the correct computer based on port forwarding rules. So how can a software application manage port forwarding if the packet must GO to the computer running this software application in the first place, meaning that port forwarding already is successful in the first place?
