- What is some piece of Computer Science or programming knowledge that *you* think is "core" but not enough people seem to know?
- git commit -m "attempt to fix CI" ... git commit -m "attempt to fix CI" ... git commit -m "attempt to fix CI" ... git commit -m "attempt to fix CI" ... git commit -m "attempt to fix CI"
- Some people seem to be incapable of seeing the commentary on the wastefulness of RAM and CPU resources in modern software development that the rest of us are trying to make.
- Me: Do you have long compile times? Students: yeah Me: how long is long Students: a full clean build can be 5 minutes! Me: ok... Moving on to the next topic...
- Please don't make your programming language so that it parses floats differently depending on the locale of your user's computer.REMINDER When you parse a float, it takes into account the language on the computer you're using. Some cultures use a period for decimal points, while some use commas. More than once have I gotten game breaking bugs due to forgetting about this.
- Theory: every aspect of modern technology hinges on C++ Evidence: JavaScript engines, browsers, Windows, KDE, JVM all written in C++. Python is C, but all major libraries are written in C++. GTK on Linux? Your C compiler is written in C++ Do you have counter examples?
- Hot take: if you need multiple large monitors to program with, you should consider writing smaller/simpler functions.
- To my fellow C++ programmers: {} : "braces" [] : "brackets" () : "parenthesis" <> : "angle brackets" Remember, it's "braced-initialization" *not* "curly bracket initialization"
- Remember: std::move doesn't move std::forward doesn't forward And std::function isn't a function
- I just finished my C++ Best Practices book - 45ish Simple Rules with Specific Action Items for Better C++ It's meant to be quick and actionable. leanpub.com/cppbestpractic… To celebrate here's a coupon for the first 100 buyers only, get it for only $7.99! leanpub.com/cppbestpractic…
- I've decided to give away over 130 HOURS of C++ material. FOR FREE! Check it out! 👀
- This is going to sound a bit trite, perhaps, but about 95% of the performance problems I fix in code come down to simply "don't do more work than you have to." It's almost never some fancy new algorithm that's needed, it's more like "stop re-parsing the same string 1600 times."
