My rule of thumb is: the more stuff put into a single statement, the higher the cognitive load. So I tend towards preferring code in smaller, easier to grasp sequential statements, rather than packing a lot of behavior into a single statement — because it is easier to code review and easier to maintain. I work with some brilliant developers who hold the opposing view, and would rather cram everything into one statement. The compiler doesn't care, and the optimizer can optimize either style really well. So use whichever works best for your team. — Eljay 44 secs ago

Q: processing exec.cmd stdout/stderr pipes output

LogicDaemonI'm learning go, and writing helper functions for easy processing of commands output. I want to concurrently read from two pipes (stdin and stderr) and process their output. The functions should work, but they look dirty with redundant code. It's only two pipes, but what if there were 10? How do ...

Q: As part of the model for a web crawler, I want to store the parts of a URL to a database using Entity Framework. Is this a good solution?

matt-in-the-hatInstead of trying to parse a URL into its component parts myself, I thought I could inherit from the System.Uri class and add a BaseEntity Id for the Entity Framework. But, VS Code complains with a message like "'Hyperlink.' hides inherited member 'Uri.'. Use the new keyword if hiding was intended."

Q: Update large object partially on events

Apoorva ChikaraI am having a large object which might grow in size. I want to update some properties on each event, there are multiple events like click, navigating to specific routes, taking prints and a lot more. I am able to do it using Object.assign(targetObject, keys). Currently, I am using the Assign meth...

 
I'm not sure you want to do this honestly; the problem is that increasing that size "accidentally" is easy and can have high cost; so if someone anywhere makes a bigger derived instance, suddenly code "far away" starts requiring more memory. Imagine someone deriving with a class that is 10x larger than prior. Silently, costs to store all derived instances balloon. What I'd do is inject a constexpr auto largest_derived = ##; in the class definition, which people writing derived classes that trigger your static asserts must update manually. Then in code review it can be caught... — Yakk - Adam Nevraumont 19 secs ago

Dwarf Fortress is one of those oddball passion projects that’s broken into Internet consciousness. It’s a free game where you play either an adventurer or a fortress full of dwarves in a randomly generated fantasy world. The simulation runs deep, with new games creating multiple civilizations with histories, mythologies, and artifacts. I reached out to him to see how he’s managed a single, growing codebase over 15+ years, the perils of pathing, and debugging dead cats. Our conversation below has been edited for clarity.
