- Immutable releases announced at GitHub Universe! Once tagged, releases can’t be changed. No more worrying about malicious actors swapping out assets or moving tags. Single-use version tags with signed attestations. This is the supply chain protection open source really needs 🔒 #GitHubUniverse

- I chat with @mikael.barbero.tech about security happenings at the Eclipse Foundation My favorite project they have is helping projects generate #SBOMs, but there's a lot happening. If you want to see some public examples of how to do security right, give it a listen!

- Reposted by Mikael BarberoTo implement robust mitigations across Geomys, I did a survey of open source project compromises in 2024/2025. Three root causes dominate: phishing, control handoff, and unsafe GitHub Actions triggers. All three can be systematically avoided. words.filippo.io/compromise-s...
- Reposted by Mikael Barbero🏷️ Reason #3.7.2 why it's critical to clearly and publicly define your #OpenSource project #Governance, for code, distributions, trademarks, and domain names. And, of course, not breaking norms and cosplaying a public charity while bowing to a sole sponsor over the community. 😢

- Reposted by Mikael Barbero🇺🇸Happy Fourth of July🇺🇸 This year, I'm wearing my 𝐑𝐞𝐬𝐢𝐬𝐭 shirt to show my patriotism. I'm reading the declaration of independence as I always do on this occasion. Several of King George's offenses against the colonies resonate this year. Here they are, verbatim:
- Iwata Satoru was an unconventional CEO. In all the best ways that could imply!
- Reposted by Mikael BarberoI will be damned if I allow a bunch of Confederate-waving January 6th apologists give the American people a lecture on flag waving. There is ZERO reason to enter an argument about patriotism with people who still worship traitors to America 150+ years later. They. Are. Breaking. The. Law.

- Reposted by Mikael BarberoThis is inaccurate. There is no known vulnerability with Signal's core tech. The memo was discussing phishing attempts, which Signal has worked to mitigate. And it was hastily reported. It's important not to spread misinfo that can confuse people into moving away from meaningfully private comms.

- Reposted by Mikael BarberoTrudeau: "He talked about banking again today in a tweet, which doesn't make any sense because 16 banks are currently active in Canada holding about $113b worth of assets in this country... what he wants is to see a total collapse of the Canadian economy, because that'll make it easier to annex us."

- Reposted by Mikael Barberoif literally anyone involved stopped to think about this for more than two seconds, they might realize it’s based on the idea that all mistakes can be fixed. which is wrong. which is why move fast and break things should never be used anywhere near a government, where mistakes kill people.
- Reposted by Mikael Barbero-= We hoped we never had to do this but here we are and we now have to do this. =- American trans humans are under threat and like in 1930s Germany, they now have to GTFO of their home country. We have decided we need to collect some information on the possible ways out. So we made a wiki.
