33% English (US) - honor, color, neighbor

Why are top three of my feed posts about something called "disposable barbecues?" Do I even want to know?

Fellow Canadians, what is your go-to source for laptops these days? Both of my (very much grown up now) kids need one for their school and I'm past the point of getting them Chromebooks, because they are short-lived jank that upload everything to the mothership.

I've been buying System76 for work, but their laptops are expensive and I have to pay high import fees -- plus they are US-based.

My current thinking is some basic Lenovo stuff, but maybe I'm missing something great.

Please, no need to mention Framework -- not interested.

I just found out about "ujust toggle-tpm2" to set up luks and tpm2 integration on boot.

Clearly, we live in the future.

I've dropped anubis difficulty back to 5 and added more mitigations to compensate. Let's see if this helps.

TCP: request_sock_TCPv6: Possible SYN flooding on port [::]:443. Sending cookies.

It's not the cookies I want to send...

If bot attacks get bad enough, is setting up a fallback tor-only node reasonable?
41% Yes, and I like the idea
32% Fine, but I hate the idea
23% No, this is just going to be wasted effort
2% What is TOR?

In-between tweaking sysctl entries for tcp and restarting nginx, I've released b4 v0.16.0:

https://lore.kernel.org/tools/20260805-alluring-arrogant-grouse-ece17a@meerkat/T/#u

If you've tried "b4 review" in its first release and found that it annoyed you too much, it may be worth trying it again, as there was a lot of churn based on everyone's feedback.

I also added the initial "b4 bugs" support that integrates git-bug and distributed bug tracking. It's not ready to go fully yet to replace bugzilla, but we're hopefully getting there once the web submission frontend is ready to go.

E.g. b4's own bug tracking is here:
https://git.kernel.org/pub/scm/utils/b4/b4.git/bugs/

(but you'll have to stare at the Anubis screen for a good minute to see it, sigh)

git.k.o is now being SYN-flooded. Not sure if on purpose or because of bugs in scraper bots.

I have evidence that bots are now solving anubis difficulty 5. Unfortunately, at difficulty 6 the site becomes usable only to extremely patient people...

Reminder for Western Europeans:

The so-called β€œwar in Ukraine” will manifest as a series of war crimes and acts of terror viewed through phones with footage that gets closer and closer to where you live until you're the ones filming.

Our new Amsterdam servers are live. The EU can now be the primary home for Fastmail data, and like our US locations, it's our own hardware, racked and run by our own people. Nothing rented from a big cloud provider.

Already a customer? Switch regions in your settings. Thinking about it? You choose your region at signup.

Our CEO Bron's post walks through exactly what lives where, because we figure you'd read the fine print anyway.

"residential proxy network" is what you call a botnet when it's run by a corporation that will never be prosecuted for doing something that would land a 13 year old in jail for the rest of their life
