It was great to get back out on the mound for the first time this year against @Ramblrbaseball and throw 3 scoreless innings for @WildkitBaseball. Looking forward to a competitive season.

The only thing the college football playoffs has proven so far is that 12 teams is too may 🥱

RIP Billy
6 Aug 2024
We are deeply saddened by the passing of our friend and colleague Billy Bean, MLB’s Senior VP for Diversity, Equity, & Inclusion and Special Assistant to the Commissioner. Billy, who fought a heroic year-long battle with Acute Myeloid Leukemia, was 60. Over the last 10 years, Billy worked passionately and tirelessly with MLB and all 30 Clubs, focusing on player education, LGBTQ inclusion, and social justice initiatives to advance equality in the game for all. Billy’s 10-year playing career included six Major League seasons with the Tigers, Dodgers, and Padres. Commissioner Rob Manfred called Billy “one of the kindest and most respected individuals I have ever known” and someone who “made Baseball a better institution, both on and off the field.”

Since February 15th, the NVD has only analyzed 59 CVEs and currently has a backlog of ~2,200 CVEs. If this is not affecting your vulnerability management program already, it will start too soon.

In the fourteen days since Kernel.org became a CNA, they have published 367 CVEs, or just over 21% of all CVEs during that time frame. It is unclear if this is just them clearing their backlog or if we should expect the 20% increase to continue.
