Hello! 👋 I haven’t lost the desire to blog, nor have I decided on Digital Detox, it’s just that I’m currently busy moving. Instead of continuing to program my own stuff after work and pouring my thoughts into blog articles, I had to pack boxes. Today was my last workday in the home office in the old apartment, Monday is the first workday in the home office in my new apartment. Then my blogging frequency will probably remain rather low, because I still have to clear out the old apartment, but I may have a little more time again. 😊 Out of curiosity, how many times have you moved already?

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…

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.

My public VPS is now only accessible via SSH from my tailnet. One more possible attack vector less.

Just noticed, but I have hit the 1000 posts mark on my English blog this month! 🎉
