Redirects

I’ve now configured a redirector within Google Cloud to handle redirects from the old blog and point them to the WordPress-centric domain. Essentially doing what wordpress.com was doing while the domain was still with them.

I’ll leave this in place until I decide what to do with the blog.

Disconnecting Domain

I’m going to be disconnecting the domain from this blog probably in the next month or so.

I’ll move the domain off WordPress and plug in a redirect to bring it back here for those who have bookmarked my articles.

I booted Linux 292,612 times

And it only took 21 hours.

Linux 6.4 has a bug where it hangs on boot, but probably only 1 in 1000 boots (and rarer if using Intel hardware for some reason). It’s surprising to me that no one has noticed this, but I certainly did because our nbdkit tests which use libguestfs were randomly hanging, always at the same place early in booting the libguestfs qemu appliance:

[    0.070120] Freeing SMP alternatives memory: 48K

So to bisect this I had to run guestfish in a loop until it either hangs or doesn’t. How many times? I chose 10,000 boots as a good threshold. To make this easier I wrote a test harness which uses up to 8 threads and parses the output to detect the hang.

After a painful bisection between v6.0 and v6.4-rc6 which took many days I found the culprit, a regression in the printk time…

What if you were invited to your own funeral?

I posted this a while ago.

But given I’ve had my uncle lose his fight for life, and my uncle’s mother-in-law also lose her fight for life, I wanted to reference this article again. This article might be about speeding, but there’s an important point within in — you have a chance to speak to your family. To your loved ones. Right now. Talk to them, call them, write to them.

The Linux commands you should NEVER use (Hewlett Packard Enterprise)

The classic rm -rf / is there, along with accidental dd‘ing or mkfs‘ing the wrong disk (I’ve done that before), but the lesser known fork bombs and moving to /dev/null are in there (I often redirect output to /dev/null, but not moved files into there. That’s an interesting way of getting rid of files.
