Is it possible to replace your fingertips? Disassembling some Lego Technic has scraped mine… And tomorrow is the handover of keys for my first own apartment!

Why didn’t I think of the very helpful Go module “net/http/pprof” earlier? This way I can profile my blog live. 🤓 (And hopefully find parts that I should or can optimize.)

What a good feeling when the hours you have invested in optimizing and testing actually bear fruit. In other words, my blog now uses less than 100 MB of memory, even though I have quite a few features enabled. My diary for example needs less than 20 MB. And if you compare that with WordPress, where the database alone needs more than 300 MB… 😄

Ok, so I have now installed CloudReady, switched to the beta channel as well, but I can’t use Linux because my CPU is not secured against Spectre/Meltdown and CloudReady doesn’t come with microcode updates. Until that comes, my ThinkPad will probably only be for browsing, watching videos, and blogging…

Update: Fixed it.

I probably spend more CPU cycles optimizing the program than the program optimization will save in CPU cycles. 🤔

I need to wait an hour for another train, but why wait at the train station?

It seems that mobile reception along German high-speed train routes has improved lately (at least compared to 2019). I’m sitting in an ICE 4 between Hanover and Hamburg, and I’ve initiated a speed test via USB tethering. My mobile phone contract is limited to 10 Mbps, but I seem to be able to take full advantage of that.
