Linux training

Linux is not one skill. It is a stack, from the kernel that talks to the hardware to the systems that run factories, labs and startups, and each layer has its own people, tools and ways of learning. This page maps the stack, shows where recognised training already exists, and describes what we want to build under Clark for industry, for students, and for anyone prototyping something real.

Aspirational. We do not currently offer any of the courses named here, and nothing on this page can be booked. Where we describe what we would do, we say “would”.

Why it matters here

Linux is the quiet foundation under a great deal of modern industry. It runs the supercomputers on the TOP500 list (every one of them, for several years running), a great many of the servers behind online services, and a large share of the embedded devices in machines, vehicles and instruments. It is also free to inspect, change and build on, which is why it is the natural tool for a student with a small, inexpensive board and a founder with a product idea. For a region with a manufacturing past and a making future, knowing Linux well is a durable advantage.

The stack, from the kernel outward

Layer	What happens here	Where paths exist
Kernel and drivers	Scheduling, memory, and the drivers that let software talk to hardware. Where Linux itself is written.	The Linux Foundation's free kernel development course and its internals course
Embedded and real-time	Building a purpose-made Linux for a device: bootloader, kernel, filesystem. Meeting hard timing deadlines.	The Yocto Project; real-time support (PREEMPT_RT)
Operating systems	Users, storage, networking, services and day-to-day administration.	LPIC-1 and LPIC-2, LFCS, RHCSA
Security, virtualization, containers	Hardening servers, running workloads in containers, orchestrating them, keeping services available.	LPIC-3 streams, Kubernetes (CKA), LPI DevOps Tools Engineer
Industrial edge and safety	Control logic and analytics on industrial computers, and Linux where failure has real consequences.	Vendor programs; the ELISA project
Prototyping and robotics	Single-board computers, sensors, robots, and the path from bench prototype to product.	ROS 2 and its community; board makers
Everyday use	The command line, files, packages and scripting. Where everyone starts.	Linux Essentials, LFCA

Credentials that already exist

Unlike manufacturing, Linux has mature, well-known certification. Three families cover most of it:

Linux Professional Institute — vendor-neutral. Linux Essentials for beginners, then LPIC-1, LPIC-2, and four LPIC-3 specializations (mixed environments, security, virtualization and containerization, high availability and storage). It also offers a DevOps Tools Engineer credential.
The Linux Foundation — the LFCA as an entry point, the performance-based LFCS for system administrators, and Kubernetes certifications such as the CKA.
Red Hat — the RHCSA, a hands-on exam on Red Hat Enterprise Linux, with the RHCE above it. Vendor-specific, and widely asked for.

For course content, schedules and fees, go to those bodies; we would rather point you to the source than restate it.

In traditional and advanced industry

Factory floors are changing from boxes of dedicated hardware to software running on standard computers. Siemens sells a virtual PLC that runs on its industrial PCs, and open source projects such as OpenPLC bring PLC logic to ordinary Linux machines. Since kernel 6.12 the real-time extension (PREEMPT_RT) is part of the mainline Linux kernel on supported architectures, so deterministic control no longer needs a separate patch set. Where safety is at stake, the Linux Foundation's ELISA project works with industry to show that a Linux-based system meets safety requirements. All of this is moving quickly, which is why a local place to learn it and ask questions is worth having. It also connects to our Manufacturing training, where automation and emerging technology overlap with everything above.

In prototyping, school and startups

A student can begin on a small board and a free course. The kernel development course from the Linux Foundation is free and teaches how to build a kernel, write and test a patch, and work with reviewers, which is a real credential in open source. A founder can prototype on a single-board computer, use ROS 2 for a robot (it runs on hardware like Raspberry Pi and NVIDIA Jetson, with Python and C++), then move to a custom image for production. That is the whole arc, from idea to product, on one open platform. We are also testing Integrated Production Environments built on open tools as part of what Niagara Assembly builds for its Membership.

What we would do

Start people well. Install days and command-line evenings for complete beginners, and study groups for LPI and LFCS exams.
Build things. Weekend labs where a group takes a board from nothing to a working, purpose-built system, or gets a first patch reviewed.
Bridge to industry. Talks, demos and tours where shops that run Linux on their floors show how, and what they wish new hires knew.
Mentor. Match people at each layer of the stack with someone one or two layers further along.
Teach what nobody certifies. Clark Courses on the practical glue: debugging a boot, reading a datasheet, moving from prototype to production. They carry no vendor credential and are labelled as ours.

What we need

The stack is wide, and no one person covers it. We are looking for:

Sysadmins, embedded engineers, kernel contributors and controls people who use Linux and would teach, mentor or give a talk.
Shops and labs that run Linux in production and would host a visit.
Boards, sensors, benches and test gear, lent or donated, for hands-on sessions.
Students and founders who will tell us what they cannot find.
Training providers and colleges interested in working with us.

Register as an expert, put your name on the list, or write to office@niagaraassembly.com. If you have tools or space to share, post them on the Board.
