As Transportation Secretary, I could always count on a Congressional Republican to take credit for an infrastructure win that they had voted against. That's the type of behavior that makes people cynical about politics - but it doesn't have to be that way.

The Hidden Cost of Poor Database Design... Bad design is more expensive than bad hardware. Poor design leads to: excessive I/O, lock contention, slow queries, and higher CPU costs. Fixing design early saves millions later.

Continuous child sexual abuse charges down to 60 days in jail and NO sex offender registry? Huge congrats to Ken Paxton’s prosecutors for negotiating on behalf of a predator instead of a child. Calling this a "defense" is pure nightmare fuel for every Texas parent. #momsky#sheshed

Dear Texans: Here's an election pro tip. If a candidate won't debate You don't vote for them. Period. It's that simple. By not debating they're saying you're concerns are not a priority. Vote for those who will debate. They have plans and value your concerns. Vote Talarico! Vote Hinojosa!

Moving the logic is easy; moving 40 years of interconnected #Db2 data without breaking downstream analytics is the real challenge!

Craig S Mullins @craigmullins.bsky.social · 23/09/2026

Db2’s concurrency model is one of its greatest strengths because it was designed to support large numbers of simultaneous transactions while protecting data integrity and maintaining predictable performance.

Creating a historical #Db2 environment shouldn't require a time-consuming UNLOAD/LOAD marathon. UBS Hainer's BCV5 automated copy workflows can reduce CPU & elapsed time by 90% ore more. They're demonstrating it on Sept 16. Check it out if you manage large amounts of Db2 #data! tinyurl.com/WNRcsm2

Audits. Forensics. Production incidents. Sometimes you need more than a backup. You need to know what #Db2 data looked like at a specific point in time—and you need it to be consistent. Watch this webinar to see how UBS Hainer's BCV5 can accomplish this tinyurl.com/WNRcsm2

A #Db2 image copy is useful. But multiple copies taken at different times do not give you a transactionally consistent view of the database. On Sept. 16, UBS Hainer will show how BCV5 uses inflight log processing to create a consistent historical Db2 target, w/o disrupting prod tinyurl.com/WNRcsm2

The same idiots who think Trump, who dodged the draft five times, knows how to win a war also think Trump, who declared bankruptcy six times, knows how to run the economy.
That's what Trump

One of the biggest mistakes enterprises can make is underestimating the complexity of #data management and governance.

Mainframe JCL and job schedulers seem to me to be perhaps the first orchestration software. They are used to coordinate and run programs (Dev) and utilities (Ops). The concept has expanded, sure. But the idea is the same.

Craig S Mullins @craigmullins.bsky.social · 26/08/2026

Everybody has their own opinions I guess. DevOps orchestration allows for more consistent, reliable operations by coordinating the various automation scripts and procedures that organizations have developed.
