Managing TLS certificates has become pretty crazy: Over the years validity was cut down from several years to two years to one year to half a year now. In a few years it will be only a little more than one month, with the additional requirement to basically continuously prove domain control.

Since I'm not using Let's Encrypt over here, these days I have to re-submit a CSR to my certificate provider every half a year for every domain, prove domain ownership, install the new certificate (chain), and update my DANE/TLSA records. Soon continuous domain control validation will have to be added as an additional secondary process to the domain reactivation/renewal process.

Reblogged NGI Zero open source funding @NGIZero@mastodon.xyz

On August 8, a new batch of 60 free and open source projects was selected for the NGI Zero Commons Fund.
We want to thank these project teams for working on the digital commons and contributing to open, secure and trustworthy digital infrastructure for all.
This brings the total of grantees within the programme to 494 projects. There are still two more calls currently under evaluation for the program.
Meet the projects! https://nlnet.nl/news/2026/20260808-60-new-projects.html

Reblogged Prototype Fund @PrototypeFund@mastodon.social

The Prototype Fund is growing!
With “Resilience,” we’re now funding not only data security and software infrastructure but also alternatives to tech giants and their centralized ecosystems.
Under “Up and Coming,” we aim to specifically support people who are new(ish) to the #FOSS world.
In total, this means up to 19 million euros in additional funding for software developed by the civil society! 🎉
