Mattress Store Experiments With Non-Blowout Sale RICHMOND, VAโ€”In a radical departure from its established tradition of total liquidation extravaganzas, Northside Mattress Warehouse on 112 Chamberlayne Rd. will use this coming weekend to test a sales...

Yeah, blowout sales always sounds like something painful after eating at Taco Bell the day before. I'm good with stores that have "fairly low prices". #TheOnion

A Vector Function by Any Other Nameโ€ฆ In my ongoing review of Oracle Database 23aiโ€™s vector functions, there was some confusion about which distance functions are equivalent, what the aliases are for a few of the specific vector โ€ฆ

Aliases, relatives, and distances: oh my!

Visualizing Multi-Dimensional Vectors from Oracle Database 23ai One of the key features of Oracle Database 23ai is creating multi-dimensional vectors and storing them alongside relational data in your tables. As I was investigating how vector datatypes were stoโ€ฆ

I did this with 23.7 in the pre-built VirtualBox appliance:

alter system set inmemory_force=base_level scope=spfile;
alter system set inmemory_size=256m scope=spfile;

Of course there is only so much memory to work with, but I see this at the PDB level:

I'll never tire of taking an #Oracle database query that runs for hours and never finishes, making a minor tweak to the query structure, then seeing it run in a few seconds on #Exadata.

There are so many of them they had to join tables. Of course, in this case the tables can be joined with a database link but finishing a conversation took a lot longer than expected because of the high latency between each of the cloud providers even when they're in the same alcohol domain (AD).

It's hard to quantify quality, but I was impressed with the detail I was getting with the 14b model. Looks like a bit over 1/s when I asked about TPS calculations. :)

Deepseek-r1 14b actually runs on my Raspberry Pi 5 with 16 GB. A bit slow, but I asked it two questions about Lollapalooza. Its "thought process" is rather odd, it's painfully slow on a Raspberry Pi, but it got the answer to both questions right. Eventually!
