Here are my notes:https://databaseweekoctober2019sf.splashthat.comDatabases on AWS: The Right Tool for the Right JobI'm not taking super deep notes for many of these talks. I'm focusing on the highlights.PostgreSQL came after MySQL.8 categories of DBs on AWS:RelationalKey valueDocumentIn-memoryGraphSearchTime seriesLedgerSearch for: AWS Database ServicesFor relational, they have Amazon Aurora. It's compatible with MySQL and PostgreSQL. It has 5x throughput compared to MySQL (on RDS) and 3x compared to PostgreSQL (on RDS). It can scale out to 15 read replicas. It's fault tolerant and self-healing. It keeps 6 copies of the data across three AZs. It can provide continuous backup to S3. It has encryption at rest and in transit. It's fully managed by Amazon. They support cross region (unclear) and multimaster.Amazon.com itself uses Aurora at least for some stuff.There's a database migration service.They also support other DBs such as SQL Server using RDS.Next, she c…
Yup. Sure took long enough for The Industry to recognize
Is Object-Oriented Programming a Trillion Dollar Disaster?
*Sigh*, I don't think everyone agrees just yet. When I interview
people, I really like testing whether they can code in an OOP style *and* in a
functional style (closures, map, recursion, etc.). Aside from the OOP connection to
mutable state, I wish more languages had stronger support for immutable data,
especially when it comes to concurrency. I like the immutable by default idea.

I see the problem as OOPs being the sausage casing that all / most problems are
supposed to be ground up and shoved into it. It's the straight-jacket that

Here is the popularity of various manually-installed *NIX shells according to how often they've been installed within the last 30 days via Homebrew:ShellPopularityzsh44809bash21737fish9307tcsh236ksh69Note, these counts are for people who have manually-installed the shell. Presumably, most people probably just use the built-in version of bash.
I started reading Kubernetes: The Complete Guide To Master Kubernetes (March 2019 Edition) and almost immediately had to put it down. I don't get it. All the other reviews were so good, but the text of this book is literally terrible. It's like a non-native speaker was leaning on Google Translate and was in a hurry to get things out the door.For instance, on p. 8, it says, "It will also run on vacant metal machines." I think the author meant to say, "It also runs on bare metal." On the same page, it also says, "The main objectives of Kubernetes is to hide the complexity of managing a fleet of containers by providing REST arthropod genus for the needed functionalities." What the heck is "REST arthropod genus"?I generally lean toward O'Reilly books because their product is generally so good. However, in this case, the O'Reilly book's ratings were pretty bad. I don't know how this book got the highest ratings other than to s…
