⚠️ Let's Encrypt Halts Certificate Issuance After Cross-Signed Root Certificate Incident

Source: https://t.co/UyHDVTTZPm

Let's Encrypt temporarily suspended all certificate issuance on May 8, 2026, after engineers identified a critical issue involving a cross-signed certificate linking the organization's Generation X root to its upcoming Generation Y root infrastructure.

The incident triggered a complete shutdown of issuance across both production and staging environments before services were restored within hours. At 18:37 UTC on May 8, Let's Encrypt engineers became aware of a potential incident and immediately halted all certificate issuance as a precautionary measure.

La universidad está llamada a ir más allá de la enseñanza de herramientas: a acompañar la formación de personas que sepan pensar con profundidad, decidir con responsabilidad y actuar con sentido ético en un entorno cada vez más complejo.

We’ve received over ¥900,000 in support from overseas fans.

Look at this.
No matter how much people argue or divide,everyone still loves manga.
That feeling is the same everywhere.

And it was proven not by corporations,but by individual fans—through their own love and respect.

(This amount is far greater than what I’ve earned from my manga volume.)

Now then… what kind of coffee should I go get?

A 10/10 repairability score doesn’t happen by accident. Lenovo’s newest ThinkPads prove that laptops can be powerful, durable, and actually repairable.

Swappable batteries, modular parts, and one of the easiest keyboard replacements we’ve seen. Learn more about what makes these laptops amazing, at the link below.

Read an amazingly clever paper today I have to share:

Imagine sourcecode that *looks* correct…but compiles to different logic!

Unicode has to support left-to-right, and right-to-left languages.

Visual order and logical order can be completely different!
