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, …

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…

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.

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. Sin…

“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 w…

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. how storage became efficient https://medi…

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…

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 eth…

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.

And Taiwan.

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.

Taiwan.

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. Source: Me. My career has been spent managing db's for internet scal…

Postgres has had CTE for a while, but not that long. MySQL 8.0 (the next version) plans to them http://mysqlserverteam.com/mysql-8-0-labs-recursive-common-t...

You missed the point of my post. You are going to have one of the two issues, either looking through two index or indexes including the a large PK. At least with InnoDB you can mak…

If you don't want a clustered index in InnoDB you can define the primary key as an auto incrementing uint.

The PG storage engine is not particularly awesome. It is basically COW (with exceptions) and compaction (called vacuum) has been quite painful for a long time. Every release it is …
