Agreed. It'd be interesting to have Brian Kernighan (C/unix) moderate a panel discussion with Frank Soltis (OS/400) and Michael Stonebraker. (If OpenAI Sora could create a compelling video of that, I would declare GenAI solve

Appreciating Stonebraker, and the concept of layering an OS on a DB, I went to see how this OS handled basics like console IO, file IO and networking and stumbled across their Hello World app. https://docs.dbos.dev/getting-s

I have gotten jaded about ESR, but this post was spot on and had an awkward but effective mix of respect, flattery, warning/rebuke, care. Linus's subsequent wildly successful development of git makes them both look shrewd.

See my other post in this thread. The authors are from China so English is not a plus for accessibility in their market’s business users or analysts.

I have one very practical question, having hit frustrations pushing data from our data warehouse into Salesforce (I see you have a Salesforce adapter). When you push data into Salesforce, and Salesforce (API) returns error messages indicati

I recall this hitting our startup’s various MySQL Linux servers in 2012. They were slow/maxed out for a while till we figured it out. The DBA rebooted a few but didn’t know why and it kept cropping up on others; I drilled into root cau

If it’s easy/cheap to build 1-2 TB RAM systems, why are there so few I can rent from AWS? I settled for 768GB when I tried a few months ago and it wasn’t cheap. They did have like one HANA class system that was multi-TB at even crazier

Sigh. Sorry. Not sarcastic, I actually really appreciated your comment. Been working in this space 20+ years and you speak truth.

I wonder if you could just 3D-print a mold and then pour the aluminum in as part of a 3d printer like this, rather than use a nozzle, and you'd get better quality/resolution.

I ask why people want to work here (or similarly “what do you want from your next position”) as a basic check of whether their and my motivations are aligned and how strong their motivation might be. Sure people can lie, but it also helps c

Not speaking about GDPR, but your post is triggering me (my issue, not yours). Here’s what is crazy to me about employee PII (personally identifiable information) being considered sensitive. Say in a well designed system you can audit who m

Wow, what an astute comment! Thank you! P.S. to the original person concerned about this though… for your own sake and your successors, please keep trying.

Pro tip side note: You can use DNS to mitigate the pain of changing those connection strings, decoupling client change management from backend change process, or if you had foresight, not having to change client connection strings at all.

Good point about Tandem, but it wasn't limited to them. Checkpoint/restart has also long been a high-end capability found in HPC (High Performance Computing) systems. I recall it even it made it onto some commercial UNIXes, althou

For analytics, use a columnar database. There are even other AWS Postgres-oriented options (check the pricing first): ZeroETL from Aurora Postgres to (postgres-compatible) Redshift (Serverless?)

Thanks! Yeah, mental models of db/DDL structure via changesets is really only meaningful the original engineer. The difficulty of that is why I never maintained views or stored procedures or user permissions as delta-like changeset. T

Ok, on balance I do not advocate putting logic, particularly iterative or nontrivial parsing logic, in the database, but the more analytical and SQL-oriented/friendly the logic is and your infra/data is, the more tempting it can b

This makes a lot of sense to me, thanks for boiling it down. Compilers can predict the code instructions coming up decently, but not really the data coming up, so VLIW doesn't work that well compared to branch prediction and speculativ

I’d be interested in understanding why the compilers never panned out but have never seen a good writeup on that. Or why people thought the compilers would be able to succeed in the first place at the mission.

You are right there will be a flamewar, and others will discount some of what you say because of your bias, you will get criticism and personal remarks (mostly off base) and you will suffer tremendous heat for it. I have been there in a pas

MrPowers, I suspect there is a case to at least attempt to make against Iceberg, but it is strange you aren't making it. Per your blog: https://mungingdata.com/devrel/virtuous-content-cycle-develo... "This po

This is a weird comparison to make nowadays. A more relevant question is Delta Lake vs Iceberg.
