Re: We will be moving to GitHub
Mark, it is good to know that a decision has been made so that we can move forward. Is there a summary document that discusses the options examined and why others did not meet the requirements? I am -NOT- trying to dredge up arguments about the choice. I am guessing that there have been some. If this fact-based decision was based solely on the fact that the BDFL prefers GitHub, please just say so.

I have probably re-learned Perl 12 times. If you will not need to maintain any existing code, go directly to Python 3.x. Not every third-party support Python 3 yet, but it is coming for most. If you can eschew 2.x, then do. Maintaining a source base targeting both 2.x and 3.x can be done, but it is not always a simple picture. Learning a new language at 45 is a great idea. Do it again at 65. -- https://mail.python.org/mailman/listinfo/python-list

As you might imagine, I am not always able to specify which OS is deployed. That does not mean that I am not responsible for getting the work done. Perhaps you will tell me that what I want is not a daemon. BTW, I thought that pip would know that python-daemon would not run on my machine, but it had no complaints installing it. That gave me unmerited hope. I want to create a program that will run a list of command lines. Some of the tasks might take 42 milliseconds, but others might take 4.2 hours. I need to be able to: - list the tasks currently being run - kill a task that is currently being run - list the tasks that are not yet run - delete a task not yet run from the list - add tasks to the list The goal is to load the machine up to a specified percentage of CPU/memory/io bandwidth. I want to keep the machine loaded up to 90% of capacity. It is important to monitor more than just CPU utilization because the machine may already be over-committed on memory while CPU utilization is low. Adding more processes in such an environment just makes the system go slower. I realize that high-end schedulers like IBM/Tivoli, CA7, and BMC might do things like that. Those are not usually within budget. Is a daemon what I need? Any other suggestions? -- https://mail.python.org/mailman/listinfo/python-list

I fully understand that Windows is not a proper UNIX. It might be that UNIX is not in each and every aspect a proper Windows.
