Software rots man. It can be really hard to run some open source software from the 80s and 90s. This is actually one of the big arguments for Open Source: Access to the software is way less interesting than the support/community/ecosystem around it; there's no reason not to open source your software and not doing it actually harms the users.
- dagmx 4y agoYeah, Pixar literally had to spin up VMs of their old software stack when they had to remaster the Toy Story films because it was less work than getting it running again on their current stack
- simondotau 4y agoActually, it seems to me VMs are an ideal way to preserve things like that. Perhaps it should be standard procedure for the archivists of such big films to build and preserve a fully functioning, self-sufficient rendering environment in the form of a virtual machine.
- tgv 4y agoUntil we switch to another architecture. It's pretty likely the x86 architecture will be gone in a few decades. Rebuilding VM software to run on new hardware is probably harder than fixing bugs in a JPEG decoder.
- adrianN 4y agoBut you only have to rebuild the VM software once to get access to all kinds of software that ran on that architecture.
- fragmede 4y agoA few decades? The IBM System/360 architecture is still being shipped, and that first shipped in 1965!
- tgv 4y agoNobody ships a PDP11 or VAX anymore. 6809? 6502? I think even the one ubiquitous 8080 isn't being produced anymore. And when IBM falls, System/360 will also be gone. There will be a transition period in which everybody scrambles to convert their systems, but after that it's EOL.
- usrn 4y agoI know someone who got hired recently to get PDP11 software running in an emulator to control an industrial process.
- tgv 4y agoI expect that to happen to /360 as well (there's more than one emulator; there's even support for the old consoles), but the hardware will be gone. And --in case of the JPEG2000-- once x86 is gone, it'll be an old decoder running on an old, unsupported OS running on unmaintained VM software running on a hardware emulator (which will also have a limited support). Not a great outlook.
- alophawen 4y agoDude, that's why we use Virtual Machines. We will run them thru QEMU or another multi-architecture solution.
