I hadn't heard about that UNIX "Princeton port" before. Thanks! Also TIL: Eric Schmidt worked on that port apparently ( https://en.wikipedia.org/wiki/Amdahl_UTS ), in addition to or around the same time

The finest contribution of AIX to Unix, copied (with varying attempts at improvements) by its 90s competitors and eventually into Linux, was its jounal filesystem. The order of magnitude improvements to fsck on bootup and overall filesytem

This article leaves out a lot of history of the lithium-ion batteries -- there were tons of companies using them in the late 80s and early 90s. I ported software for testing them under various temperatures for use in down-hole horizontal dr

Pardon me an old story... I never built a double entry accounting system but decades ago I did build a billing system for a internet/telcom startup that grew to a modest 8 figures revenue. By accident and not knowing any better as a yo

I've seen them when shopping for certain CAD-certified laptops. There are some of these out there, from major brands (HP?). Asus seems to have more. ( https://rehack.com/reviews/best-laptops-without-webcams/

Any insight based on histogram of the timing of this person's posts, particularly ones responding to a just slightly earlier post? (ie was clearly awake and not an artificially-delayed response). Krebs knows about this timezone analysi

It's just a lighthouse engineer's form of marking the territory they built/operated like a modern day software easter egg. Their life's work was not a romance or linguistic creation, for better or worse. "Just the

Believe me, there's a lot of plumbing moving stuff from point A to B and dealing with poop ("dirty data" is the industry euphemism) in the data engineering and data analyst space. In my more analytic moments I try to convince

This article was discussed last week on HN but based on the author's blog post rather than ArsTechnica who is seemingly syndicating it to a larger audience. Original discussion: https://news.ycombinator.com/item?id=4205

So Regatta has an in memory cache? Does the posix disk write only suceed when the data is in more than one availability zone?

So it looks like you don't use postgres extensions so you can run this on an EC2 against an Aurora Postgres instance and dump files to S3 Iceberg right? And can you then have Glue Catalog auto-crawl them and expose them in Athena? Or a

The article credits two academics (Hinton, Fei Fei Li) and a CEO (Jensen Huang). But really it was three academics. Jensen Huang, reasonably, was desperate for any market that could suck up more compute, which he could pivot to from GPUs f

Liquibase does support rollback DDL with MySQL; I used it. I put each DDL in a Liquibase changeset with a corresponding rollback DDL I constructed by hand. If the Liquibase changeset failed, I could run the rollback for all the steps after

Is it a rowstore or a columnstore? Have you considered an HTAP design? You mentioned thread safe, is it multithreaded so it takes advantage of multiple cores?

Considered doing the migration via Liquibase? I dont know that it supports parallelism in the migration process but you could do most of the rest in it (pre/post migration scripts, rollbacks, test cases (within precondition changesets)

Kinda crazy question, but why not support SQL table/column DDL (nested JSON or arrays within those for bonus points)?

Export/import without masking, a few times a year, with masking generally not required. This was my first masking in recent times, but I may have half a dozen more times in the next year if/as we do more POCs with full data volume

Free feedback for you, nothing personal... Within 48 hours of needing to do some masking (exporting data from a database to CSV to import it to a less trusted domain's database for testing/benchmarking), I ran across your HN post

A few things to keep in mind: 1) It's possible (however unlikely?) you weren't the only candidate to mention the idea 2) I sometimes ask candidates how they would handle tricky dilemmas I face; yeah, it's free consulting in a

How/when/why did the word "base" get added to "data" to form the concept of a "Data Base"? The article mentioned CODASYL-era the term was used but wondering where it started...

For the curious, "x32" Linux is a "L64P32" programming model. There is some lwn.net 2012 commentary on performance implications at: https://lwn.net/Articles/503541/

If I recall correctly, UNIX vendors in the late 90s were debating a fair bit internally and amongst each other whether to use LP64 or ILP64 or LLP64 (where long longs and pointers were 64bit). ooh, found a link to a UNIX Open Group white pa

i am not sure on what basis Cory Doctrow indicated the Greek scandal was undertaken to affect bids for Greek games rather than safety of Greek games. Is there any evidence one way or another?
