Published 3 articles so far, but working on AI architecture and management. While most people are focused on prompt engineering and making stuff with AI; I'm more interested in how it actually works, how to size workloads, how to maximize performance, the security and safety aspects. Here is my most recent article where I played with benchmarking tools to get a baseline and understand how configurations impact token generation

Professor Madhavapeddy, am I understanding your comment correctly? "without having to seek permission slips signed in triplicate", the motivation to create Docker was because of IT bureaucracy?

I've been trying to use tools like these for data aggregation, analysis, and finding trends. One major issue I experience with almost every product is I will tell it to "sort by column x" and it either doesn't do it, or will state that it did it when in fact it did not do the sorting.

I'm surprised either of them didn't pick up that this is a meme, for what, 20 years?

How did you select the hardware? Did you do a bake off/poc with different vendors? With the intention of being in different countries, are you going to leverage the same hardware at every DC? What level of support SLA did you go with for your hardware vendors and the colo facilities? And my favorite, how are your finances changing (plus pros cons) by going capex vs opex?

Really cool, do you have pictures or a blog post about this?

Yea agree with you there. Do any new ones come without mics these days though?

Bought a Hisense tv for two reasons: status light turns OFF when the TV is on, and there is a physical disable switch for the microphone. Verified both in reviews and in person before buying.

Electrical tape for everything else.

Has anyone done the math for how much "coffee" EV drivers consume vs ICE drivers? Wonder what the extra costs are for EV drivers while waiting for a charge.

Anyone have good examples of rule 8, namespaces? Either in pg or SQL server?

Takes CO2 and extracts one oxygen molecule. Really neat they can do that with Mars' thin atmosphere .

Does anyone know if there is a similar process that can separate both oxygen molecules and the carbon molecule? Then use the C to 3d print things and the oxygen to breathe/fuel/etc? Probably energy limited?

I've done 2.5 billion digits in 88 seconds with ycruncher. That's about 28.4 million digits a second?

Though that is with a broadwell CPU and about 3 years ago. Might see if I can get my hands on a 6348 ice lake CPU and see how she burns.

Yup, I wrote about them from an HP conference in 2010 and remember being told about them for a roadmap item well before that: http://ewams.net/?date=2010/09/05&view=hptechforum2010

Another one of those "right around the corner" things that is always coming soon.

Good point. And different in different regions such as Texas vs NY. Upstate NY vs New York (the city). Even in the same cities within different cultural areas just blocks away from each other!

Then when it pops all the people with means will buy it up to invest and those without will still be in the same situation, or worse.

Re fireplace - check out a ventless system. They can change existing burner and logs with ventless which gives you lots of heat that a vented system won't. Can get a decent one for 600-1200 bucks.
