This is only my understanding so if you need a better/formal explanation, I recommend reading through the memory model for your given program...

The iconic 1996 "Space Jam" website was recently relaunched to promote the new movie. Thankfully, the developers still kept the old site around to preserve its intergalactic legacy.It’s not often that a website stays up mostly unchanged for 25 years.

This is a follow-up post to my previous article comparing Zutty to various other X terminal emulators. That assessment, while going into a lot of detail, missed an important aspect: the typing latency of each program.

And if the native byte order really does matter to the execution of the program, it's almost certain to be dealing with some external software that is either wrong or misguided. If your code contai...

I have been keeping a wee .org file of gotchas in the defaults of Go’s various net packages for a while now. I pull it up each time I’m building a service with the standard library, just to make sure I don’t miss something that I have already hit in the past.
