Tock's design centers around protection, both from potentially malicious applications and from device drivers. Tock uses two mechanisms to protect different components of the operating system. First, the kernel and device drivers are written in Rust, a systems programming language that provides compile-time memory safety, type safety and strict aliasing. Tock uses Rust to protect the kernel e. Second, Tock uses memory protection units to isolate applications from each other and the kernel.

Tock is documented in the doc folder. Read through the guides there to learn about the overview and design of Tock, its implementation, and much more. Follow our getting started guide to set up your system to compile Tock. Head to the hardware page to learn about the hardware platforms Tock supports.

Also check out the Tock Book for a step-by-step introduction to getting Tock up and running. Find example applications that run on top of the Tock kernel written in both Rust and C. There are also generated source code docs. We encourage contributions back to Tock and are happy to accept pull requests for anything from small documentation fixes to whole new platforms. For details, check out our Contributing Guide. To get started, please do not hesitate to submit a PR. We'll happily guide you through any needed changes.

Check out the blog where the Talking Tock post series highlights what's new in Tock. Also, follow talkingtock on Twitter. You can also browse our email group and our Slack to see discussions on Tock development. The Tock project adheres to the Rust Code of Conduct. All contributors, community members, and visitors are expected to familiarize themselves with the Code of Conduct and to follow these standards in all Tock-affiliated environments, which includes but is not limited to repositories, chats, and meetup events.

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache The Tock Project Developers include dozens of contributors, some on behalf of their university, company, or organization. The most up to date list of contributors is available in the git history: git shortlog -s -n. Note: the above list may be incomplete.CSe is an experimental course offering in operating systems. Students should expect the course to have rough edges since it is the first offering.

In CSe, students implement a simple, clean operating system virtual memory, processes, file system on a Raspberry Pi 3 in the Rust programming language and use the result to run a variety of devices. CSe uses up-to-date software modern programming languages and tools and hardware bit, multicore architectures. CSe explores the details of bare-metal software including the boot process and device drivers in the context of an embedded platform, the Raspberry Pi.

Everything happens in the physical world; CSe does not use emulators or virtual machines. Similar to CS, CSe also aims to provide a wholistic introduction to operating systems concepts such as protection and isolation through mechanisms such as virtual memory and processes.

This course consists of lectures, five assignments, a midterm, and a final exam. This course also consists of optional labs.

Lectures are held twice a week and primarily cover theoretical and conceptual operating systems fundamentals. Assignments guide students towards implementing an operating system from scratch on a Raspberry Pi 3 in Rust.

The expected workload is 10 - 15 hours per week per assignment. Labs are held twice a week. Lab sessions give students an opportunity to work on assignments with guidance from course staff and cooperation with other students.

Labs are optional but students are highly encouraged to attend at least one lab session per week. Your grade will be a function of your class ranking and where we set the thresholds for letter grades. Our decision on grade thresholds will factor in class participation a second time.

There will be two exams. The final exam is cumulative but will focus primarily on the material in the second-half of the quarter. There will be five assignments. The intent is to 1 practice operating systems concepts and 2 add new tools to your systems programming toolset. Except for assignment 0, you will be given approximately two weeks to complete each assignment.

We expect that each assignment will take 10 - 15 hours per week to complete. Toggle navigation CSe.

Check this list to see when support for your Operating System will end. A system is "unsupported" when the developer is no longer issuing any software patches or security updates. For WindowsXP, that happened on April 8, From that point on, the operating system is stagnant. It may be working fine until that point, but Outdated system software is itself in violation of the security requirements because it cannot support encryption or possibly additional applications needed for security.

As other technology advances beyond the capabilities of the hardware and the operating system, an outdated machine will cease to be able to run other vital software: anti-virus updates, software patches, other applications running on the machine. The hardware itself, as it ages, will become more difficult to use and more costly to repair. Eventually, an obsolete system becomes vulnerable to attack in a number of ways. Phishing emails are the most common cause of compromise.

No recent antivirus updates means that the system is still vulnerable to viruses that may be circulating, but from which newer systems are protected. A lack of recent software patches means that hackers can directly attack the system, by exploiting known and still-existing bugs in the operating system. And even without any network connections, web, or email access, a machine can still be compromised by an embedded virus on any external device such as an external hard drive or USB stick.

Perhaps even the hardware itself may be vulnerable to compromise. Even if it feels like you've been running your system normally, an expired operating system can still result in a compromised system. You may not even notice it's happened. If a machine has been compromised, it means an unauthorized person has access to the University's private information and to your own private information as well, and they can steal that information to use for their own purposes.

Unpublished research data and other valuable information is at risk. So are your login credentials, for the Stanford networks but also potentially for your bank or other sites which you personally access. If your computer has been compromised, attackers may use that foothold to gain entry to Stanford's wider network, or they may use your computer as part of a botnet, sending spam or perpetrating other attacks.

You may not even be aware that it's happening. If your computer can be upgraded from an unsupported operating system, by either upgrading the software or replacing the hardware, that's what you should do! By keeping your computer up to date and compliant with Stanford security guidelines, you are protecting the University, your colleagues, and yourself.

Upgrading the operating system from WindowsXP is free for Stanford-owned computers; for more information, visit the Essential Stanford Software page.I love reading about, thinking about, designing, building, and most of all, understanding operating systems, cryptosystems, and programming languages.

I've worked on a range of projects in the past, from designing anomaly detection algorithms at Google, to developing new languages for programming robots at MIT, to working on operating systems that operate rockets and spacecraft at SpaceX. I spend my time researching topics related to operating systems and programming languages at Stanford, where I've been working on my PhD since Fall, I was at MIT before that. Sergio Benitez.

I am not currently seeking full-time employment or start-up opportunities. I'm Sergio. I'm a computer science PhD student at Stanford.

I graduated from MIT. Here's a bit more detail Places I've worked at At SpaceX I worked with the platform team to improve the boot times of flight hardware. This involved changes to the bootloader, kernel, drivers, initialization systems, and flight software runtime. As a result, search queries run 4x faster on average on OS X At Google I worked with the Gmail performance team to decrease server downtime by detecting anomalous behavior before server failure.

I designed and implemented an original anomaly detection algorithm based on local outlier factors. I've founded or developed the technical foundation for a couple of technologically oriented companies. Papers recently published Sergio Benitez.
