Sampler is a tool for shell commands execution, visualization and alerting. Configured with a simple YAML file.

The license is pretty restrictive in that the software can only be used by a single user.



Flame graphs are a visualization of profiled software, allowing the most frequent code-paths to be identified quickly and accurately.

The x-axis shows the stack profile population, sorted alphabetically (it is not the passage of time), and the y-axis shows stack depth, counting from zero at the bottom. Each rectangle represents a stack frame. The wider a frame is, the more often it was present in the stacks. The top edge shows what is on-CPU, and beneath it is its ancestry.

Flame graphs can be generated from any profile data that contains stack traces, including from the following profiling tools:

GitHub is blocking users in Crimea, Cuba, Iran, North Korea and Syria from accessing its services to comply with U.S. trade control laws.

The Microsoft-owned company disclosed the action on a support page as a courtesy, noting that GitHub users ultimately are responsible for ensuring that their use of GitHub’s products and services complies with all applicable laws and regulations.

The blocking is based on source IP address and payment history for GitHub Pro accounts. GitHub states that developers are not allowed to use VPNs to circumvent the ban. However, this is just an ongoing game of cat and mouse. The developers this ban has blocked are those technical enough to research ways to evade being blocked.
