Hey everyone! Fedora 22 is on the cusp of being released and the Fedora Cloud Working Group has elected to organize a test day for May 7th in order to work out some bugs before shipping it off to the rest of the world. With a new release comes some new features and tools. We are working on Vagrant images as well as a testing tool called Tunir. Joe Brockmeier has a nice writeup about Vagrant and Kushal Das maintains some docs on Tunir. |

Callbacks in Cplex I used LazyConstraintCallback to implement a Branch and Cut algorithm with CPLEX, but when I implemented and run this algorithm, it was very slow if I compare it with its version that doesn't use callbacks in Cplex. The reason is because ControlCallback(LazyConstraintCallback is a ControlCallback) switch Cplex to sequential mode by default and turn off dynamic search. I wrote this post, because I didn't find this information in Cplex's documentation, I only found it in this technical forum. |

By now most Fedora email lists have been migrated to Mailman3. One little (but killer) new feature that I recently discovered was that Mailman3 includes the RFC 5064 Archived-At header in the emails. This is a feature I have wanted for a really long time; to be able to find an email in your Inbox and copy and paste a link to anyone without having to find the message in the online archive is going to save a lot of time and decrease some latency when chatting on IRC or some other form of real time communication. |
