Does this not speaks to the rapid growth of Central Europe economies rather than a decline of Japan? I have read similar comparisons for both the U.K. and Germany vs Poland.

Also, a quick googling suggests both Poland and Japan both have fertility rates around 1.2. Working age of Poland is 65% of the population vs 60% for Japan. So a bit worse.

Oddly enough I am visiting Japan right now. There are lots of foreign workers in service jobs. They speak zone language and don’t jay walk.

Prices feel like a middle income country, but that is just the Yen sucking. Otherwise it feels very first world.

They are however incredibly loud. Being close to someone shooting 556 with a brake is a really annoying experience and I would not be shocked if there were follow on effects.

rwultsch — Mon, 17 Jun 2024 18:28:52 +0000

I am an overweight person that drank more than I should. Ozempic helped me drop 15 lb and I don’t feel the draw of drink nearly as much as I had.

I was diagnosis ADHD as a kid. Since being on Ozempic I have noticed no difference in ability to hold attention.

“Introduced in 2013, HBase was Pinterest’s first NoSQL datastore.”

I don’t think this is correct. When I started in late 2013 Redis was being used as a persistent data store. And what pain it was. I convinced leadership in late 2014 this was a bad and they had me keep it alive until it was replaced by MySQL in mid 2015.

HBase was nothing but pain at Facebook where it was supposed to replace MySQL and then Pinterest where… I think there was hope it would replace MySQL. Once I automated MySQL at Pinterest I think it wasn’t so bad, particularly given the absurdly limited staff they gave the problem.

I enjoy that “ma” has ambiguous meaning above. Does it mean mandarin question mark word or does possibly mean mother?

A pin was a 1.2 KB json blob. There were other tables but pins was the big one. Why MySQL? It did not destroy data like the alternatives.

Before I joined in late 2013, they had not known how to run schema change without downtime. Once we fixed the kernel the db’s were nearly completely untaxed in terms of performance. They did however need large instances due to disk usage.

I am getting a Sub-zero in a few weeks which is damn near the most expensive fridge. It does not have nice pull out shelves or the veggie compartments.

I expect the sealing and ethylene scrubbing will keep veggies fresh linger.

We recently moved to Frederick, MD. Walking distance to the very lively downtown, inexpensive housing, close to an airport, yada, yada...

OT: How is the tech scene in Taiwan?

My wife is from Taiwan. Every time we visit I am very sad to leave. We have thought about moving to Taipei.

FB had plenty of schema changes. I know, I wrote software to push them out. The important concepts for pushing schema at scale became part of Skeema.

Eh, I will kind of buy that. It was a church before it was a mosque and churches tend to have quite a bit more music than mosques.

The race war comment above seemed uncharitable.

The Hagia Sophia was the site of a significant massacre when it was forcibly converted from a church to a mosque.

I was on the DBA team there around that MAU. I had lots of company and support from SRO (aka jr DBA's) as well as other teams (provisioning, etc...).

Short duration: network, bad software deploy Long duration: db. If you break data, it takes a while to unbreak.
