I have encountered this problem numerous times, now. It really makes me believe that the models do not really understand the topic, even the basics but just try to predict the text.
One recent example was me asking the model to fix my docker-compose file. In it, there's the `network: host` for the `build` part. The model kept assuming that the container would be running with the host network and kept asking me to remove it as a way to fix my issue, even though it wouldn't do anything for the container that is running. Because container runs on `custom_net` network only. The model was obsessed with it and kept telling me to remove it until I explicitly told that it is not, and cannot be the issue.

I've been through an iPhone moment, and I moved past it once I realized that I'm getting screwed and I have no control. Now I'm back to Android (Pixel with GrapheneOS specifically) and self-hosting.

I would avoid using SD cards and go for something else like M.2 or NVMe for storage. SD cards tend to be on the lesser side in terms of performance, failure rate, and silicon quality in general.
Let's Encrypt stopped its certificate expiration email notification service a while ago, and I hadn't found a replacement yet. As a result, I didn't receive an expiration notice this time and failed to renew my certificate in advance. The certificate expired today, making my website inaccessible. I logged into my VPS to renew it manually, but the process failed every time. I then checked my cloud provider's platform and saw a notification at the top, which made me realize the problem was with the certificate provider. A quick look at Hacker News confirmed it: Let's Encrypt was having an outage. I want to post this news on my website, but I can't, because my site is down due to the expired certificate.
Because you're not supposed to rely on emails. You should have an automated certificate renewal in place. I'm under the impression that Let's Encrypt wants to reduce certificate validity even further from the current 90 days.

Makes total sense to me. But why hasn't this been done a long time ago? Pretty sure people spotted this earlier in TCP and UDP but this was never implemented?

I get the impression that the person who wrote this article doesn't know much about docker. Running 2 apps and a certbot can be done without containers easily. Try running 20 apps, some of which depend on having the same dependency but on a different version.
Regarding security, it depends on how you set up your containers. If you just run them all with default settings - the root user; and give them all the permissions, then yeah, quite insecure. But if you spend an extra minute and create a new non-root user for each container and restrict the permissions then it's quite secure. There are plenty of docker hardening tutorials.
Regarding ease of setup, it took me a while to learn docker. Setting up first containers took very long time. But now, it's quick and easy. I have templates for the docker compose file and I know how to solve all the common issues.
Regarding ease of management, it's very easy. Most of my containers is setup once and forget. Upgrading an app just requires changing the version in the docker-compose file.

Here's the gist:
For nearly 50 years theorists believed that if solving a problem takes t steps, it should also need roughly t bits of memory: 100 steps - 100bits. To be exact t/log(t).
Ryan Williams found that any problem solvable in time t needs only about sqrt(t) bits of memory: a 100-step computation could be compressed and solved with something on the order of 10 bits.

I don't think Germans want faster trains, they want punctual ones. How about trying to set a record for trains being punctual?

I'm very interested in how they've implemented Google Analytics. No external JS is loaded, just 9KB of packed JS embedded implementing a minimal call... and then it is being sent to their own script analytics4.php which acts like MITM. Does anyone know the name of the plugin or package they are using?
