Best/better because yes, QA actually existed and was important for many companies - QA could "stop ship" before the final master was pressed if they found something (hehe as it was usually games) "game breaking". If you search around on folklore or other historical sites you can find examples of this - and programmers working all night with the shipping manager hovering over them ready to grab the disk/disc and run to the warehouse.

HOWEVER, updates did exist - both because of bugs and features, and because programmers weren't perfect (or weren't spending space-shuttle levels of effort making "perfect code" - and even voyager can get updates iirc). Look at DooM for an example - released on BBS and there are various versions even then, and that's 1994 or so?

But it was the "worst" in that the frameworks and code were simply not as advanced as today - you had to know quite a bit about how everything worked, even as a simple CRUD developer. Lots of protections we take for granted (even in "lower level" languages like C) simply didn't exist. Security issues abounded, but people didn't care much because everything was local (who cares if you can r00t your own box) - and 2000 was where the Internet was really starting to take off and everything was beginning to be "online" and so issues were being found left and right.

For example, you had to know which Win32 functions caused ring-3 -> ring-0 transitions because those transitions could be incredibly costly. You couldn't just "find the right function" and move on. You had to find the right function that wouldn't bring your app (and entire system) to its knees.

I specifically remember hating my life whenever we ran into a KiUserExceptionDispatcher [0] issue, because even something as simple as an exception could kill your app's performance.

Additionally, we didn't get to just patch flaws as they arose. We either had to send out patches on floppy disks, post them to BBSs, or even send them to PC Magazine.

In any case some of the software from before 2000 was definitely better than today, i.e. it behaved like being absolutely foolproof, i.e. nothing that you could do could cause any crash or corrupted data or any other kind of unpredictable behavior.

However, the computers to which most people had access at that time had only single-threaded CPUs. Even if you used a preemptive multitasking operating system and a heavily multi-threaded application, executing it on a single-threaded CPU was unlikely to expose subtle bugs due to race conditions, that might have been exposed on a multi-core CPU.

While nowadays there exists no standard operating system that I fully trust to never fail in any circumstance, unlike before 2003, I wonder whether this is caused by a better quality of the older programs or by the fact that it is much harder to implement software concurrency correctly on systems with hardware parallelism.

At the time of release, yes. They had to ensure the software worked before printing CDs and floppies. Nowadays they release buggy versions that users essentially test for them.

Yes. The incentives for writing reliable, robust code were much higher. The internet existed so you could, in theory, get a patch out for people to download - but a sizeable part of any user base might have limited access, so would require something physical shipped to them (a floppy or CD). Making sure that your code worked and worked well at time of shipping was important. Large corporate customers were not going to appreciate having to distribute an update across their tens of thousands of machines,

No. The world wasn't as connected as it is today, which meant that the attack surface to reasonably consider was much smaller. A lot of the issues that we had back then were due to designs and implementations that assumed a closed system overall - but often allowed very open interoperability between components (programs or machines) within the system. For example, Outlook was automatable, so that it could be part of larger systems and send mail in an automated way. This makes sense within an individual organisation's "system", but isn't wise at a global level. Email worms ran rampant until Microsoft was forced to reduce that functionality via patches, which were costly for their customers to apply. It damaged their reputation considerably.

An extreme version of this was openness was SQL Slammer - a worm which attacked SQL Servers and development machines. Imagine that - enough organisations had their SQL Servers or developer machines directly accessible that an actual worm could thrive on a relational database system. Which is mindboggling to think about these days, but it really happened - see https://en.wikipedia.org/wiki/SQL_Slammer for details.

I wouldn't say that the evidence points to software being better in the way that we would think of "better" today. I'd say that the environment it had to exist in was simpler, and that the costs of shipping & updating were higher - so it made more sense to spend time creating robust software. Also nobody was thinking about the possible misuse or abuse of their software except in very limited ways. These days we have to protect against much more ingenious use & abuse of programs.

Furthermore today patching is quick and easy (by historical comparison), and a company might even be offering its own hosted solution, which makes the cost of patching very low for them. In such an environment it can seem more reasonable to focus on shipping features quickly over shipping robust code slowly. I'd argue that's a mistake, but a lot of software development managers disagree with me, and their pay packet often depends on that view, so they're not going to change their minds any time soon.

In a way this is best viewed as the third age of computing. The first was the mainframe age - centralised computer usage, with controlled access and oversight, so mistakes were costly but could be quickly recovered from. The second was the desktop PC age - distributed computer usage, with less access control, so mistakes were often less costly but recovering from them was potentially very expensive. The third is the cloud & device age, with a mix of centralised and distributed computer use, a mix of access control, and potentially much lower costs of recovery. In this third age if you make the wrong decisions on what to prioritise (robustness vs speed of shipping), it can be the worst of both the previous ages. But it doesn't have to be.

I hope that makes sense, and is a useful perspective for you.

Literally the moment everyone got on the internet, pretty much every computer program and operating system in the world was besieged by viruses and security flaws, so no.

There was a point in time where both windows wasn’t constantly bsoding and Microsoft’s primary objectives weren't telemetry and slop coding.

Huh. Direct debugging, in assembly. At that point, why not jump down to machine code?
