I finally wrote about my method for optimizing interval search—something I promised a long time ago! It ended up being quite lengthy, so I turned it into a series: 👉 orasql.org/2024/12/19/int… #Oracle #SQL #DatabaseOptimization #IntervalSearch
Partitioning by node (instance_number): orasql.org/2024/12/12/par… #oracle #gc #rac
Just published part 2 of my mini-series on index usage tracking just posted. It may receive some updates over the next few days if questions appear in the comments: jonathanlewis.wordpress.com/2024/03/20/ind…
How do I identify indexes that could be dropped - just started a short series about Index Usage Tracking that can you some decent insight into how effective your indexes are: jonathanlewis.wordpress.com/2024/03/15/ind…
If you're doing these things, please stop, or maybe consider a career change: 1) posting the same question in multiple internal Slack/Teams/Whatever spaces 2) saying "it does not work," with no details 3) sharing pictures of code 4) preceding 1-3 with 'Hi' and nothing else
16th London Pytorch Meetup will take place Next Thursday (October 5). 3 speakers covering deep technical topics: RLHF, Diffusion models, differentiable physical simulation. Register now meetup.com/london-pytorch… Orgs: me and @FedorShabashev Thanks to @RevolutApp for hosting.
Does anybody know how to make Home/End buttons work in @OracleSQLDev on Macbook m2? @thatjeffsmith @krisrice ? PS. Don't know why ~/Library/KeyBindings doesn't work for Slack and Oracle SQL Developer ¯\_(ツ)_/¯

Ok, I like #chatGPT 🤣 How much does Sayan Malakshinov know about #oracle database: PS. @oracleace, #chatGPT says I'm an Oracle ACE Director 😉
I wonder why dbms_adr/dbms_adr_app, and even dbms_system.ksdwrt, are not documented. It would be useful for developers to have access to them in rare, exceptional situations. #oracle #documentation #alertlog
#31 🤣
