BMC Software's corporate blog with technical introductions to machine learning, Spark, ElasticSearch, Db2, Tableau, and Wardley mapping.
HN comments give no opinion of the blog. A BMC employee also posted a freelancer job ad for BMC's websites in the comments.
I'm so excited for Supabase. As soon as they move Realtime Subscriptions out of alpha / beta, I will replace Firebase on all new projects. The Firebase / Firestore analog - Snapshot Listeners - give your application a real-time backend for free and simplifies state management drastically since your subscriptions are your store.
Supabase being built on SQL is interesting to me- I love PSQL and the row-level security rules are incredible. But the historical SQL v NoSQL debate involves the trade-offs of Consistency, Availability, and Partition Tolerance [0]. With Firebase (and typically NoSQL) you lose Consistency and you get a bit of redundance by virtue of using onWrite listeners as opposed to Joins. That model scales really well since it's amenable to sharding seamlessly. What will scaling a Supabase backend look like?

Seeking Freelancer | BMC | Part-time | Remote
BMC has a number of websites, these are the main ones: https://www.bmc.com/ (AEM) https://www.bmc.com/blogs/ (WordPress) http://communities.bmc.com/ (Jive)
I'm looking for a person to help improve our website UX/UI, improve on our consistency of patterns and elements, help design A/B tests and experiments, and that sort of thing. Our DevOps team handles implementation and most coding.
Probably 20 hrs per week, 6 month contract to start, and see how the role grows.

Why should it be so hard to believe? A mainframe box is about the size of a rack of servers, and all the components are much more tightly integrated. Plus the utilisation on m/fs is much higher than on normal servers.
I don't have benchmarks, but googling "mainframe energy efficiency" brings up a load of results, eg:

This happens so often on HN, and it is so god damn frustrating. I'm literally a fucking expert, telling you the best thing to do, and explain why, and I get downvoted for it. The next person who tells me in a comment "explain your opinion! you're not helping!" when I don't write an entire novel to justify my position, I'm going to link back to this thread. Pointless.
I've gone to the trouble of googling these articles for you (it took me a whole 30 seconds!). Please read any of…
You can have fun with Wireshark https://www.wireshark.org/
Depending on the details in each of the layers[1] you might be able to spoof traffic towards it to trick it things.
you may need to try MITM the certs/key exchange stuff[2], hopefully they have a broken implementation that doesnt validate signatures etc.

It is important to carefully look into the functional context where that abstraction is used.
If you are looking for example into System Integration, Data Integration, ETL and so on, not using a canonical format from the beginning, will get you into the type of almost exponential grow in mappings between sources and targets.
