Optimality vs. Stability of Feedback Control Systems.
A system under the effect of an optimal controller may not necessarily be stable. 
Control Commons
Just a random collection of stability, continuity, existence, and uniqueness theorems for nonlinear control 
What Good Research is Not
Curated quotes from the 'good citizen of CVPR' session at CVPR 2018. 
What's behind IEEE RAS Best Conference Papers?
... our paper bridged the strong theory with relevant practice, and made it work on real robots. 
On the necessary and sufficient conditions for optimal controllers
Necessary and sufficiency conditions, differentiability and continuity assumptions, and analytical solutions to optimal control problems. 
Should I use ROS or MuJoCo?
Good controller algorithm formulations are based on numerical optimization ... 
Twanging git pull, push and clone
It is useful being able to share one's work among different computers using native git commands such as merge, fetch, push, clone, or pull without resolving to using ssh, scp which are without the benefits of diff and merge strategies of git. 
Ubuntu16.04 and Cuda8.0 Install Guide
Installing NVIDIA/CUDA Libraries, without breaking Xserver in Ubuntu 16.04. 
PyTorch and rospy interoperability
Avoiding pitfalls and potential landmines when installing and using the pytorch neural network framework in rospy. 
Backpropagation and convex programming in MRAS systems
A contraintbased approach to solving the backpropagation optimization problem in nonlinear model reference adaptive systems. 
Control Theory and Machine Learning

Cloning specific folders from git
...[sic] sparse checkoutallows us to sparsely populate the working directory by using skipworktree bit to inform GIT if the file in the working directory deserves a look. 
Optimal Control: Model Predictive Controllers.
Optimal controllers belong to the class of controllers that minimize a cost function with respect to a predicted control law over a given prediction horizon. 
Mathematical Modeling of Robots.

Safely upgrading your linux kernel.
We are telling GRUB to use the lastsaved selection, do an auto bootup after 5 seconds if user does nothing, and inform all kernels to reboot after 10 seconds if they die completely. Note, the TIMEOUT option is disabled in GRUB 2.02
