We talk to the developers behind MenuetOS: an operating system written entirely in assembly language

MenuetOS is an operating system that is super-fast and can fit on a single floppy disk (remember them?)

Is either version of Menuet used in any production environments? Do you see this as a hobby/educational exercise or are you aiming for a system that will fill a particular niche in the operation system ecosystem? That is, is there a target audience for Menuet, or is it all about the development process?

Madis: The most important about Menuet is its small footprint as it still fits on a floppy. The niche can be some embedded device. What is also important is that its x86-based and therefore portable to most compatible devices. Now that Mac is using Intel CPUs and future Larrabees from Intel will also be using a subset of x86 ISA.

Ville: Menuet is used in environments that require real-time control over other devices. Currently Menuet is mainly used among hobbyists who are interested in assembly language. And assembly niche is actually a pretty sweet one. There are new exiting features to learn and most importantly, you never know what kind of usages people come up with. Our team's current goal is to get the version 1.0 out.

Menuet

Do you think there is still a role for assembler language beyond MenuetOS? Most computer science courses these days seem to concentrate on high-level languages like Java and C++, and most job openings seem to be for people with training in those languages (or other high-level languages like PHP and Visual Basic).

Madis: There are parts in code where ASM is still needed. Of course rare are the cases where a whole program is coded in the dialect, but optimisation today is increasingly important and I think a role for assembler is exactly that. Higher languages fit perfectly for quick prototyping where speed isn't crucial.

Ville: Some courses are also restricted by funding reasons. Teaching must be neutral and manufacturer independent. And assembly languages have been clearly manufacturer dependent. But assembly coding itself with Menuet's high-level system calls is actually quite fast and easy to learn.

What development tools could you not live without when working on MenuetOS?

Madis: Firstly Flat Assembler (FASM), which generates code for MenuetOS. FASM's macro capabilities also help dealing with images and raw binary data. Hex-editor is also a valuable tool and an OS-debugger to test quickly the changes made on-the-fly.

Is there a reason you chose FASM as your assembler?

Ville: FASM was the first feature-rich assembler for 32 bit x86 written itself in assembly. Before FASM we used an assembler written in C. Today FASM supports multiple platforms from Windows to Linux and Macintosh.

If you’re looking to invest in your next work horse laptop for work or home use, you can’t go wrong with the MSI GE63.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.

I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.
