Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.

The steps I took to dual boot Arch Linux alongside the preinstalled Windows 10 that came with my new Lenovo Ideapad. I used Ubuntu exclusively for the last 6 years so I'm Window's illiterate. I don't know a whole lot about the inner workings of Linux either.
Prepare the preinstalled Windows to share the system.
The default formula use by AWS RDS to calculate the max_connections
parameter is: LEAST({DBInstanceClassMemory/9531392},5000)
But It's hard to find the exact value of DBInstanceClassMemory
.
So, here are the values I got when I ran the SQL commmand: show max_connections;
in some RDS instances:
Instance type | RAM (GB) | max_connections |
---|---|---|
db.t2.small | 2 | 198 |
db.t2.medium | 4 | 413 |
FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
This a collection of interesting links found in The Imposter's Handbook by Rob Conery.
