While we try our best to lock down our laptop, close open ports, run littlesnitch, ufw but it is always an unease to connect them directly to an public wifi, worrying about some 0day that allow someone in local lan to hack it.

What I sometimes do is to use my phone connecting to the free wifi and simultaneously hotspotting it to my laptop - It feels better to have something in between blocking random nmap scans.

Anyone else doing this? Is there other tricks you do?

Let’s hear it… As developers and engineers, I think we should all adopt the “assume breach” mentality.

Do you have your own personal tricks to stay safe?

I’ll start: I like to drop canary tokens on my personal machines, servers, and even in the AWS config file under the "admin" profile. I also use an old Raspberry Pi running knockd that triggers a simple bash script to alert me via Slack if someone scans my home network.

I used to have a cron job that hit my server’s website on specific URL paths, one for HTTP and a different one for HTTPS.

Each path included an encrypted version of current Wi-Fi name. Every time those endpoints were accessed, I’d get a Slack notification. The idea was that if someone managed to MITM my traffic and got curious enough to check the URLs, it would alert me.

There’s more, but I’m curious—what tricks do other HN-ers use?

Just like the title said - I have always been active & semi-fit but in recent years, I suddenly got struck with terrible muscle soreness. I would often get cramps when waking up, play sport or bad soreness after a light jog, lifting weight or doing any kind of exercise. The soreness won't go away for days, sometimes a week or two which made it really hard to do any kind of exercise and I feel sluggish all the time and this went on for ages without me knowing why and doctor just discard it as "you just need to get used to exercise and it will get better". A year ago, I was just looking for why I get these leg cramps every 2 days, someone suggested taking Magnesium and Vitamin B - This was the turning point.

Now, 12 months later and i'm enjoying my life again! I am now able to run up the hills with my kids, wake up without leg cramps at all and the soreness from lifting weight heals within half of a day or a day. I just want to share this if someone is struggling with similar problem as I recently shared it with my dad and a couple of relatives and almost everyone were having great results so it seems like a not very well-known thing. :)
