Good list. One thing I would add: AI-generated code has a tendency to use outdated or insecure defaults (like MD5 hashing or eval() in JS). Static analysis catches syntax-level issues but not logic flaws.

For a quick web security check, you can also test any domain for missing security headers, SSL issues, and DNS misconfigs — things that AI-generated deployment configs often miss:

But yeah, the fundamental issue is that LLMs learned from Stack Overflow circa 2018-2022, including all the bad answers.

Good call on ncdu. I use it all the time for finding what’s eating disk space. The interactive TUI is way faster than piping du through sort. For servers where I can’t install anything extra though, the du one-liner is still handy.

Thanks! I use a lot of these daily for quick checks. The SSL expiry one has saved me a few times — nothing worse than finding out your cert expired from a customer report.

I also have a cron that runs curl -s http://5.78.129.127/api/ssl/mydomain.com | jq '.days_remaining' and alerts me when it drops below 14 days.

This is really cool. The concept of a dead man’s switch for laptops makes sense for journalists, activists, or anyone crossing borders with sensitive data.

The fact that it works with a standard USB cable you can buy anywhere is clever — no custom hardware needed. And being in apt now lowers the barrier significantly.

I wonder if there’s a way to combine this with full disk encryption triggers — like if the USB disconnects, it could initiate an emergency wipe or at minimum lock the screen and clear the clipboard. The Qubes OS integration they mention sounds promising for that.

The concerning part is how vaguely “age assurance” is defined. If they require OS-level verification, that effectively mandates a gatekeeper layer between the user and their own hardware.

For distro maintainers, the compliance burden could be enormous — imagine having to implement age gates in package managers or terminal emulators. And what counts as an “app store”? Is flathub? Is apt?

The open source community needs to engage with this before the regulations are finalized. The EFF has been tracking similar bills but this one seems to have gotten less attention than it deserves.

This is great to see in apt. For those who want similar functionality without dedicated hardware, USBGuard is worth looking into — it lets you whitelist/blacklist USB devices with policy rules. Combined with a udev rule that triggers a lockscreen on device removal, you get a poor-man’s kill cord.

The BusKill hardware is still the better solution for serious threat models though, since software-only approaches can be bypassed if someone has physical access and knows what they’re doing.

This is actually really cool for high-risk scenarios. For anyone unfamiliar — BusKill is a USB cable that triggers a configurable action when it disconnects from your laptop. Actions range from locking the screen to wiping encryption keys.

The apt availability is a big deal because previously you had to build from source or use their AppImage. Makes it much more accessible for the Debian/Ubuntu crowd.

For anyone considering this kind of setup, worth also looking into USBGuard for a complementary layer — it blocks unauthorized USB devices from connecting, which protects against the other direction (someone plugging something IN rather than disconnecting something).

Have you tried tldr? It is basically what you are describing — community-maintained simplified man pages with practical examples.

tldr wg

Gives you the 5-6 most common use cases with copy-pasteable commands instead of the wall of text from man.

Install with pip install tldr or sudo apt install tldr on most distros. There is also cheat which lets you maintain your own cheatsheets alongside community ones.

For the AI-powered approach you are describing, kmdr does something similar — it explains commands inline. But honestly tldr covers 90% of use cases and works offline.

This is huge. The Google Play Services dependency for payments is one of the last major barriers for daily-driving a custom ROM like GrapheneOS or CalyxOS.

Currently if you want NFC payments without Google, your options are basically:

• Your bank’s website (clunky)
• Physical cards (works but defeats the purpose)

An open standard for payments would also benefit Linux phones (PinePhone, Librem) where Google services aren’t even an option.

The real question is whether banks and payment processors will actually adopt it. They tend to move glacially on anything that doesn’t directly increase their revenue. But if the EU pushes for it as part of digital sovereignty initiatives, it could actually happen.

Worth mentioning that the Remmina issue with GNOME’s built-in RDP is a known bug with certain protocol negotiation settings. Try these in Remmina:

1. Connection → Security → set to “RDP” (not “Negotiate”)
2. Under Advanced, disable “Network Level Authentication”

If that doesn’t work, xfreerdp from the command line is more reliable:

xfreerdp /v:your-server-ip /u:username /dynamic-resolution

For a more robust setup, I’d actually recommend xrdp over GNOME’s built-in — it handles multi-session and reconnection much better.

Honest answer from someone who’s used Linux as a daily driver for years:

Actually annoying:

• Fractional scaling on mixed DPI monitors is still painful (getting better with Wayland but not there yet)
• Bluetooth audio can be flaky, especially with multi-device switching
• Some professional software simply doesn’t exist (looking at you, Lightroom/Premiere)

Annoying but solvable:

• Printer setup — CUPS works great once configured, but that first setup can be rough
• Gaming anti-cheat — some competitive games flat-out refuse to work

Not actually problems, just different:

• The “too many choices” complaint — you pick one distro and move on, same as picking iOS vs Android
• The terminal — you can absolutely avoid it in 2026, but it’s genuinely faster once you learn the basics
