I have written a lot of code whose only job was to remember that some other code failed. Retries. Status tables. Cleanup jobs. Queues with sad little dead-letter queues next to them. None of it was the product, but all of it had to work.

That is the failure tax.

Durable execution is one way to stop paying quite so much of it. The idea is simple enough: record the progress of the program, then resume from the last safe point after a crash, timeout, deploy, or long wait.

In this talk I will walk through how we ended up with the reliability stack we have now, then compare two approaches that are getting real traction: Temporal's workflow-service model and DBOS's Postgres-backed model.

The fun part is AI agents. Agents call tools, wait on humans, spend money, and make choices that are hard to reproduce. Once those choices are recorded, yesterday's nondeterminism becomes today's history. Now you can replay it, fork it, and debug it without doing the expensive or dangerous work again.

When I was in college, I figured out that the education you get doesn't really change.  However, what does change is the people that you are associating with.<p>At the "elite" colleges, there is a greater percentage of smart students, which lends itself to more productive discussions and more difficult tests that force you to challenge yourself.  Also, it is like the difference between the regular classes  in high school and advanced classes -- in the advanced classes you cover the same material, but with greater breadth and a deeper understanding.<p>And the number 1 biggest advantage of going to an elite college is that you have a much better chance of meeting the world's future movers and shakers -- the people that will be the educational and business leaders of the next generation.  That alone is a good reason to go to an elite college.<p>So I have to disagree, and say that there are indeed advantages to going to an elite college, just not the advantages that most people think.
I did read to the end, but I
