Comment: Not with a bad set of requirements (Score 1) 207

Wouldn't a total re-write be the right thing to do instead?

Yes, if you can get the proper requirements. (This does not apply to the current article, since I assume that the requirements for these syscalls, etc. are well described.)

On most business systems, especially one that us written over the course of a few months, the requirements are just as spaghetti as the code, so rewriting the system from scratch might also rewriting the requirements from scratch, which is a monumental task if it already have customers with different configurations.

On a more humorous note, I find it funny that this is today's article on The Daily WTF: Seven Minutes In Heaven

Think of the fire hazard when insulation dust fills that server. Save yourself the headache and just get a NUC or something similar and put it on the bookshelves. If fire doesn't scare you, think of all the water pipes down there. I came home one day to find that my pressure regulation valve has broken and sprayed the whole crawl space with water. It was such a mess, and I was glad nothing valuable was down there.

don't allow your users to be admins on their local machines,

Ding ding ding ding ding... whenever anyone came to me for malware-related help with Windows, I make sure that they no longer have admin privileges before I let them back in. Create a separated local admin account for them if necessary, but their everyday web-surfing and mail-reading account should not need admin privileges.

On the other hand, New Scientist reported on a new approach with leaky (non-infinite) multiverse that can explain away both of these uncertainties. It's at least an interesting read.

To quote:
"THE wave function has collapsed – permanently. A new approach to quantum mechanics eliminates some of its most famous oddities, including the concept of quantum objects being both a wave and a particle, and existing in multiple states at once."

It's CS50. It's not even a 100-level classes. This is their way of saying, pay us $X for 3 course credits and see if you would even like to continue down this path.
