Old write-up about CAP Theorem

In 2011, Ken Rugg and I were having a number of conversations around CAP Theorem and after much discussion, we came up with the following succinct inequality. It was able to help us much better speak to the issue of what constituted “availability”, “partition tolerance”, and “consistency”. It also confirmed our suspicions that availability and partition tolerance were not simple binary attributes; Yes or No, but rather that they had shades of gray.

So here’s the write-up we prepared at that time.

Don’t use a blockchain unless you really need one

Now, that’s easy to say.

But, blockchain today is what docker was 18 months ago. 

Startups got funded for doing “Docker for sandwiches”, or “Docker for underpants” (not really, but bloody close).

Talks were accepted at conferences because of the title “Docker, Docker, Docker, Docker, Docker” (really).

And today it is blockchain.

I hope you weren’t counting on Project Fi …

Google’s Project Fi international data service goes down.

One of the things I have come to realize is that it is not a good plan to depend on services provided by the likes of Google.

They work 99.9 or 99.95% of the time. And they work well. But depend on them for five 9’s, that’s dumb.

Mysore School of Architecture

I happened to be at the Mysore School of Architecture, in Mysore, India and had a chance to walk around. And click some photographs 🙂 The building is bright and airy, and the pictures below show some views of this. There was a lot of art all around the campus, all of it created by the students. Some modern art under the stairs. Modern art in the courtyard. A nice painting which shows two views, depending on where you stand. A nice mural on the wall. Some lovely photos; the sun and the wind weathered the display, but the display and the captions are lovely. Many of the class rooms have nice caricatures of famous architects. And finally, some lovely origami under the stairs! I loved my short trip to the college and will surely be back when there are some students there.
