@ignaloidas this will disable TCP SACK, an optional feature without which lossy connections may suffer reduced throughput
Without disabling this, your server can be remotely kernel paniced
🚨 ⚠️ ⚠️ ⚠️
Urgent Linux advisory
⚠️ ⚠️ ⚠️ 🚨
Urgently run the following:
echo 0 | sudo tee /proc/sys/net/ipv4/tcp_sack
On all Linux hosts to work around the issue and then start patching your kernels
So Gab has decided that their own code that they spent $5M of investor money developing is so unsalvageably bad that they're going to use Mastodon's code instead, with the added bonus of leeching off of our apps (with Gab apps being banned from app stores)
This is an early warning to fellow admins to be vigilant and domain-block them on sight, when/if they appear (unconfirmed whether they intend to federate), and to app devs to consider if blocking Gab's domains from their app is necessary.

@elementary do you have a recommended list of laptop hardware for running Juno?
A year ago I tried learning ActivityPub, and more or less failed. I was confounded by a spec that was so abstract I couldn't make heads or tails of it. Turns out I was missing some key things.
I have written a guide to learning about ActivityPub that I wish existed a year ago when I first set out to learn how to write social media servers that conform to the spec:
Adobe told me I'm not allowed to use Lightroom (CC) any more, and to move to their cloud solution which requires that I store my photographs on their servers.
No thank you.
So now I'm Importing my photo archive (2011-2019) in Luminar. It's going slow. Hopefully it works.
Anyone know of any open source alternatives to Adobe Lighroom and Luminar 3?

Just recorded a short video to be included on an interactive map of technology initiatives for sustainable development. Mind you, I’ve little faith in the UN – everyone I’ve spoken to from there sounds like a mini Eric Schmidt. Very neoliberal…
(And while they’re quick to praise our initiatives, do we get any funding or support from them? Nope! Why did I record this again…?) 🤔
"May I have a ticket please?"
"Of course, to when?"
"Do you have a visa?"
"Why do I need a visa? My friend went to 1597 with no visa."
"There is enough history since then to keep it fixed. 20th century and younger is still volatile."
"Can I go to 34 AD?"

For any instance admins, here's something I'm finding useful for updates: https://gist.github.com/heliostatic/4099cc3070ad45ebd909b13aeed925fa
Thinking about re-writing my clunky Rust command line tool using clap.rs, in the hopes of (a) learning something, (b) making it more useful to users, and (c) making it easier for others to contribute.
Do any of y'all have clap.rs tutorials/examples you like? (Beyond the examples included in the repo itself, which I will try to learn from)
Dear Ruby devs and game devs. I have a crazy announcement I want to share. Please boost.
Last week I released A Dark Room to the Nintendo Switch. Within the game, I also shipped a Ruby interpreter and a code editor as an Easter Egg.
*This Easter Egg effectively turns every consumer spec-ed Nintendo Switch into a Ruby Machine.*
1. Download A Dark Room from the US/EU.
2. Connect a USB keyboard and press the “~” key.
3. Follow the onscreen instructions.
Should my recent Go-related videos have sparked some interest in learning Go programming yourself, I've just recorded & uploaded the first part of a small series of Go tutorials:
Learn Go! - Setting Up Your Workspace
This is just a start, but as you know, I always appreciate your feedback. So let me know what you think!
