Rust enters the Linux kernel

In 2022 something happened that seemed impossible: the Linux kernel, the core that runs everything from servers and phones to ATMs and medical equipment, began accepting code written in Rust. For more than three decades that heart had been written almost exclusively in a single language. Opening the door to another wasn’t a technical whim: it was a fundamental decision about how we want the software we depend on every day to be.

And why Rust? Because it’s designed from the ground up to prevent an entire family of security and stability failures—those related to memory handling—that have historically caused much of systems’ vulnerabilities and crashes. When the most critical software project on the planet decides to move in that direction, it sends a clear message to the whole industry. And that message also applies to Mexican companies that run their day-to-day on software.

What “safer software” means in practice

When we talk about security we’re not just referring to hackers or locks. We mean that your system behaves predictably: that it doesn’t crash mid-workday, that it doesn’t corrupt data, that it doesn’t surprise you with a strange error right when you need it most. Much of that is decided in how the software is built on the inside, long before you use it.

Linux’s bet on Rust confirms a trend we were already seeing: the industry is favoring tools that catch errors at the moment of writing the code, instead of discovering them once they’ve already blown up in production. It’s the difference between a system that gives you peace of mind and one that keeps you on edge.

A system’s security isn’t added at the end; it’s decided in how it’s built from day one.

Why this matters to your small business

You may never touch the Linux kernel or write a line of Rust, and that’s fine. What matters is what this decision represents for the software you do use and commission:

• Fewer costly surprises. A system built with good practices fails less, and every avoided crash is time, money, and reputation you keep.
• More reliable data. Underlying stability protects your information: your customers, your inventory, your history. Decisions with reliable information start with systems that don’t corrupt that information.
• Lower cost over the long term. Cheap software that has to be patched every month ends up being expensive. Base quality pays for itself over time.
• A higher bar for everyone. When the most serious projects raise the standard, your company deserves providers that raise it too.

Good practices, not trends

Here an honest clarification is in order: the solution isn’t to “ask for everything in Rust.” The underlying lesson is different and more useful. What the Linux community did was choose its tools with the long-term consequences in mind, not what was fastest to deliver.

That same criterion is what we aim to apply in custom software: choosing the right technology for each problem, taking care of how it’s built on the inside, and prioritizing that your systems keep your data, your processes, and your history as your company grows. Technology is a tool; what matters is that it solves your operation reliably.

How to bring this logic to your company

You don’t need a huge migration to benefit from this way of thinking. You can apply it to what you already have:

• Start with something concrete and easy to measure. Choose a process that gives you headaches today and improve it first. It’s easier to see results and correct course.
• Ask about quality, not just price. When you get a quote for a system, dig into how it’s tested, how your information is backed up, and what happens when something fails.
• Treat your data as an asset. Make sure any new system keeps your history and integrates with what you already use, instead of forcing you to start from scratch.
• Surround yourself with people who think long-term. A good technology partner doesn’t sell you the trend of the moment: they build you something that keeps working several years down the line.

That the Linux kernel opened the door to Rust is a sign of where the industry is headed: toward safer, more stable, better-thought-out software. That peace of mind shouldn’t be exclusive to the tech giants; your small business also deserves systems built to last. At Normandia Web we like to start with that process that keeps you up at night today and build it well from the base. If you want to look at how it would play out in your case, we’d be glad to talk it through.
