What are you doing, frog, are you nuts? Get inside. Turn on the AC. Take a cold bath.

Looks like I get to spend a day in Doha because they overbooked our flight to Montreal. No big, I've never actually been to the middle east.

✈️ ALA > DOH > YUL

I spent a great week in Almaty visiting my KZ cousins and meeting up with my parents. Now it's time to head back.

Hopping on an airplane to go home soon. Here are some horses from a walk earlier.

Any guesses where I have been?

Ask fedi: replicating large file collections over slow links
Show content
I have a server "primary-na" with 50TB of arbitrary content in /srv, mostly in millions of small files, many of them identical hardlinks. I have 3 other servers across the world (copy-na, copy-eu, copy-ap) where I want to have the exact replica of primary-na's /srv. These replicas may be occasionally unavailable for hours on end, or they may be occasionally slow or under high load. The content on them may also occasionally bitrot and must be identified and healed.

I've researched this multiple times over the last few years, but I've still not found a solution that would beat "just run rsync over it when something changes on replica-na." It's simple and effective, but obviously super inefficient and IO-heavy on both ends.

Any suggestions on how you would do it?

I'm umpiring 11 games in the span of 7 days. I now deeply understand Deakin's dialog line in this clip.

Just a regular reminder that the war isn't over, civilians are still murdered in their homes by cruise missiles, and war crimes are committed daily by the invasion force occupying the sovereign territory of Ukraine.

Until the 1991 borders are restored, all war criminals are in jail, and reparations are paid off, I will continue to #StandWithUkraine, and so should you.

To you, the word "applet" means:
45% Any small embeddable application
40% A java applet
13% What the heck is an "applet"?

Going through Ansible tutorials. Thus far, it's mostly ansible-lint yelling at me.

My kid spent the last 5 days building an ALU emulator in Minecraft with redstone and switches. Predictably, I've come up with a lot of "I think I just saw an actual spectre in your CPU" jokes, but thus far failed to execute them.

Not sure what's causing it yet, but our primary mirror replication speeds are down to 20Mbps from the usually healthy 4-5 Gbps. I don't think it's anything on our end, so I'll try to flag our Equinix support overlords.

If you find that mirrors.edge.kernel.org is lagging behind, that would be why.

As someone who has regretted naming something "b4" due to how hard it is to reliably search, I have to giggle at naming something "x".
