atop - System and process monitor for Linux

•    C

---

Atop is an ASCII full-screen performance monitor for Linux that is capable of reporting the activity of all processes (even if processes have finished during the interval), daily logging of system and process activity for long-term analysis, highlighting overloaded system resources by using colors, etcetera. At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks (including LVM) and network layers, and for every process (and thread) it shows e.g. the CPU utilization, memory growth, disk utilization, priority, username, state, and exit code. In combination with the optional kernel module netatop, it even shows network activity per process/thread. In combination with the optional daemon atopgpud, it also shows GPU activity on system level and process level. Resource consumption by all processes. It shows the resource consumption by all processes that were active during the interval, so also the resource consumption by those processes that have finished during the interval.

dockersh - A shell which places users into individual docker containers

•    Go

---

A user shell for isolated, containerized environments. dockersh is designed to be used as a login shell on machines with multiple interactive users. When a user invokes dockersh, it will bring up a Docker container (if not already running), and then spawn a new interactive shell in the container's namespace.

pms-docker - Plex Media Server Docker repo, for all your PMS docker needs.

•    Shell

---

With our easy-to-install Plex Media Server software and your Plex apps, available on all your favorite phones, tablets, streaming devices, gaming consoles, and smart TVs, you can stream your video, music, and photo collections any time, anywhere, to any device. The bridge networking creates an entirely new network within the host and runs containers within there. This network is connected to the physical network via an internal router and docker configures this router to forward certain ports through to the containers within. The host networking uses the IP address of the host running docker such that a container's networking appears to be the host rather than separate. The macvlan networking creates a new virtual computer on the network which is the container. For purposes of setting up a plex container, the host and macvlan are very similar in configuration.

blockade - Docker-based utility for testing network failures and partitions in distributed applications

•    Python

---

Blockade is a utility for testing network failures and partitions in distributed applications. Blockade uses Docker containers to run application processes and manages the network from the host system to create various failure scenarios. A common use is to run a distributed application such as a database or cluster and create network partitions, then observe the behavior of the nodes. For example in a leader election system, you could partition the leader away from the other nodes and ensure that the leader steps down and that another node emerges as leader.

grab - Web Scraping Framework

•    Python

---

Project Grab is not abandoned but it is not being actively developed. At current time I am working on another crawling framework which I want to be simple, fast and does not leak memory. New project is located here: https://github.com/lorien/crawler First, I've tried to use mix of asyncio (network) and classic threads (parsing HTML with lxml on multiple CPU cores) but then I've decided to use classic threads for everything for the sake of simplicity. Network requests are processed with pycurl because it is fast, feature-rich and supports socks5 proxies. You can try new framework but be aware it does not have many features yet. In particular, its options to configure network requests are very pure. If you need some option, feel free to create new issue.
