Rust does not allow function overloading or variadic functions, so a few different options are available to handle different use cases. I will not go into depth about all the options, but I want to show off one of option that I didn’t see in the blog posts I found but instead discovered while working with TcpStreams. The signature for connect() is pub fn connect<A: ToSocketAddrs>(addr: A) -> Result<Self> and it can be called with a variety of arguments, without any explicit conversion:...

It has been a very long journey with input methods for me, but I pretty much settled on the ErgoDox as my daily driver. At least when I’m at my perfect desk.

And that’s usually when my tendinitis flares up, since I use the GUI button heavily and can’t easily rebind it – but also never found a good placement for fn keys....

Why should Linux have all the fun? Configuration Find help here. Not so obviously: the configuration file path is stored in $PROFILE.

Sometimes jump tables are borked, especially when a binary has to be loaded rwx, specifically the issue is with writable memory.

The whole blob was mapped as rwx because some of the memory ranges would change, but I didn’t know which ones yet, and I didn’t want to hand-pick the ranges either....
