I prefer and recommend the very simple boglehead approach to investing. Simple 3 fund portfolio, focused on long term growth.

Lots of forums on their website, but basic idea is split your money into a healthy mix of total market, international, and some bonds. Focus on tax advantaged retirement accounts. Invest early and often.

For the record I did not downvote.

But I capitulate on your point. It would be great if every piece of software was written with resilience and uptime in mind.

As a former sysadmin that sounds like a dream. But I don’t think I have ever seen that with any mainstream program that I’ve had responsibility for. Does that mean all those programs were bad? I don’t think so. We wouldn’t need sysadmins if all programs were written the way you describe.

Programs can be written to auto rotate their logs, compact and reindex their db’s. Using browser updates as an example, they can even safely auto update and revert back on failure.

How many programs actually do these things? My experience is next to 0. But I wouldn’t call them all bad or poorly written programs.

No. Every good software program should write at least logs to disk. Every good database writes to disk. Add a new post, db will commit to the db and the db will grow in size.

Name any decent sized program where new content is added and I guarantee it writes to disk and will fail eventually if not maintained.
