A single distribution of libraries that automatically collects traces and metrics from your app, displays them locally, and sends them to any analysis tool.
The key features of OpenCensus include:
- Standard wire protocols and consistent APIs for handling trace and metric data.
- A single set of libraries for many languages, including Java, C++, Go, .Net, Python, PHP, Node.js, Erlang, and Ruby.
- Included integrations with web and RPC frameworks, making traces and metrics available out of the box.
- Included exporters for storage and analysis tools. Right now the list includes Zipkin, Prometheus, Datadog, Stackdriver, and Azure App Insights.
- Full open source availability for additional integrations and export options.
- No additional server or daemon is required to support OpenCensus.
- In process debugging: an optional agent for displaying request and metrics data on instrumented hosts.

The open source monitoring framework.
Seastar is an advanced, open-source C++ framework for high-performance server applications on modern hardware. Applications using Seastar can run on Linux or OSv.
Seastar is the first framework to bring together a set of extreme architectural innovations, including:
Shared-nothing design: Seastar uses a shared-nothing model that shards all requests onto individual cores.
High-performance networking: Seastar offers a choice of network stack, including conventional Linux networking for ease of development, DPDK for fast user-space networking on Linux, and native networking on OSv.
Futures and promises: an advanced new model for concurrent applications that offers C++ programmers both high performance and the ability to create comprehensible, testable high-quality code.
Message passing: a design for sharing information between CPU cores without time-consuming locking.
CANtact is an open source Controller Area Network (CAN) to USB interface for your computer.
Free and Open On-Chip Debugging, In-System Programming and Boundary-Scan Testing

Boot-Repair is a simple tool to repair frequent boot issues you may encounter in Ubuntu like when you can't boot Ubuntu after installing Windows or another Linux distribution, or when you can't boot Windows after installing Ubuntu, or when GRUB is not displayed anymore, some upgrade breaks GRUB, etc.
Boot-Repair lets you fix these issues with a simple click, which (generally reinstalls GRUB and) restores access to the operating systems you had installed before the issue.
Boot-Repair also has advanced options to back up table partitions, back up bootsectors, create a Boot-Info (to get help by email or forum), or change the default repair parameters: configure GRUB, add kernel options (acpi=off ...), purge GRUB, change the default OS, restore a Windows-compatible MBR, repair a broken filesystem, specify the disk where GRUB should be installed, etc.
Boot-Repair is a free software, licensed under GNU-GPL.
