I love this expression!

*The Three-Body Problem intensifies*


Oh give me a locus, where the gravitons focus, and the three-body problem is solved… [1]

That's the point, but often in many network issues, the name resolution is the root cause of the problem. Not necessarily the DNS itself. Sometimes the /etc/hosts is more than enough to cause headaches!


I've certainly added a hostname to an /etc/hosts file for testing and forgotten.

Nothing makes sense, where is this address coming from? Oh. It was me. I put it there.


YES! IBM's Fix Central, or how it's called, it's literally a maze.

And I hate Oracle's and Red Hat's paywalls, even if I can understand their presence.


Interesting! Surely there are lots of moors…


Moorhamshirecockbottom, being one.


I'm disappointed: I can't see any comments about the awful .zip file integration in modern Windows version. Extracting the files requires a pop-up or a non-intuitive context menu.


Last time I tried to use the built-in zip extraction was in XP, perhaps Win7. It was awful.

It was slow. Unzipping archived source with thousands of files could take an hour or more... or 15 seconds via pkunzip.

It didn't warn of corruption. Windows-unzip a corrupted file, and it will just stop at the point of corruption with no feedback, as though complete. Using pkunzip you'd get a warning about a corrupted file.

Being that slow, and not reporting errors are two things that really aren't acceptable. I have no idea if it's improved since then.


It sounds like it was the best it could reasonably be expected be back in the late 90s, and if it hasn't been improved sufficiently since then is probably not at all his fault.


Yes, absolutely, I didn't mean to blame him. But from Windows 95 to 11 something could have been improved, from MS.


Yes, exactly. SMS should be an option because it is obsolete, and therefore unsecure.


> Thirty years later, a lot has changed. The AS/400 has (mostly) gone

Well, not exactly. IBMi is still widely used, as an "affordable, low cost mainframe".


Fair comment. I was thinking of the original AS/400 hardware but AS/400 is used to refer the later PowerPC versions (which I guess Nadella would have been using here) and IBMi.


This rises a potential problem, often underrated by companies: some have backups with infinite retention.

It is common to have backups with retention of 10 years, some may have 20 years for legal reasons… but the majority of people don't understand the difference between "readable" and "usable".

Of course, it depends on the data… And there are companies backing up whole virtual machines with infinite retention, believing to be able to run them: it is hard enough to restore a vSphere 5.x machine on a brand new vSphere 8, I really don't understand this waste of space.


If you backup all, you can sort later, and even eventually never. It costs 1 USD per month at Google Cloud to store 1TB of data.

At this price it's not worth sorting, when one single devops costs 100 USD+ per hour, not including the opportunity cost of not working on something more productive (and less boring for the developer).

Then X years after the company is acquired, or sufficient time has lapsed, you can delete / drop the data without sorting.

Regarding virtual machines, if it's VMDK for example, you can read the raw disks without booting it, and again, it's not worth taking a risk to lose data to potentially save 10 USD per month, which is similar to one developer taking one beer extra at a team event.


> if it's VMDK for example, you can read the raw disks without booting it

Yes, but that's the difference between "readable" and "usable". Many companies don't realize the technical difficulties to be able to run the VMs. They just expect that it will work, if needed.


Often an old file or disk image is tiny compared to modern file sizes.

So the waste of space is more of an administrative character than a waste of disk space.
