• What UDP port number(s) is/are most likely to be unblocked at a client? [closed]

  - by mike

  For a custom UDP server servicing a wide variety of client machines sending custom UDP packets, what's the best port to choose as the standard listening port for the server (in that the port is not likely to be disabled at the client by a firewall or router)? My first inclination is to use port 80, since almost everyone is using HTTP, but that's TCP, and maybe blocking of UDP on port 80 has become common. What's the best port to choose?

• What command line tools for monitoring host network activity on linux do you use?

  - by user27388

  What command line tools are good for reliably monitoring network activity? I have used ifconfig, but an office colleague said that its statistics are not always reliable. Is that true? I have recently used ethtool, but is it reliable? What about just looking at /proc/net 'files'? Is that any better? EDIT I'm interested in packets Tx/Rx, bytes Tx/Rx, but most importantly drops or errors and why the drop/error might have occurred.

• Suspicious activity in access logs - someone trying to find phpmyadmin dir - should I worry?

  - by undefined

  I was looking over the access logs for a server that we are running on Amazon Web Services. I noticed that someone was obviously trying to find the phpmyadmin directory - they (or a bot) were trying different paths eg - admin/phpmyadmin/, db_admin, ... and the list goes on. Actually there isnt a database on this server and so this was not a problem, they were never going to find it, but should I be worried about such snooping? Is this just a really basic attempt at getting in to our system? Actually our database is held on another managed server which I assume is protected from such intrusions. What are your views on such sneaky activity?

• How to use HttpContext.Current on asynchronous threads?

  - by Eran Betzalel

  I've a schedule tasks mechanism (very similar to DotNetNuke's) in my business logic library (a DLL that is used by ASP.Net website). When I use HttpContext.Current inside on of these tasks, it returns with a null value, because the current async thread (or task) was not initiated from a user's request. How can I use HttpContext.Current in these asynchronous threads? P.S - I think my question is more best-practices related than technical.

• Django: Breaking up views

  - by Brant

  This is really just a "best practices" question... I find that When developing an app, I often end up with a lot of views. Is it common practice to break these views up into several view files? In other words... instead of just having views.py, is it common to have views_1.py, views_2.py, views_3.py (but named more appropriately, perhaps by category)?

• Placing custom code in a System namespace

  - by David Brown

  Are there any best-practices that state custom code shouldn't be placed in a System namespace? Should System and its children be reserved for Microsoft code? I ask because I'm writing a class library that will be used across many projects and I'd like to keep things consistent by placing it in System.InteropServices (since it deals with P/Invoke).

• How do I extend a python module? (python-twitter)

  - by user319045

  What are the best practices for extending a python module -- in this case I want to extend python-twitter by adding new methods to the base API class. I've looked at tweepy, and I like that as well, I just find python-twitter easier to understand and extend with the functionality I want. I have the methods written already, I'm just trying to figure out the best way to add them into the module, without changing the core.

• Do you continue development in a branch or in the trunk?

  - by Sam McAfee

  Suppose you're developing a software product that has periodic releases. What are the best practices with regard to branching and merging?

What do folks think is the trunk considered "gold" or considered a "sand box"?

Can someone direct me to the Microsoft recommended best practices for 64bit applications(links). Thanks in advance.
