Concurrency in Dart WHAT DART IS SINGLE THREADED!? MY IGNORANT SELF IS ENRAGED. Parallelism vs. concurrency Parallelism is when multiple tasks run at the same time on multiple processors or CPU cores.  Concurrency, on the other hand, is when multiple tasks take turns running on a single CPU core. A Problem with Parallelism The long story short of…

Well hello again, how are you? Are you eating enough? Do you need to do some laundry? We’re almost at the end of Dart Apprentice! Honestly, not bad progress i think. For someone reason I feel like this has been dragging on forver but when I look back at the first post in this series…

List Whenever you have a very large collection of objects of a single type that have an ordering associated with them, you’ll likely want to use a list as the data structure for ordering the objects. Lists in Dart are similar to arrays in other languages. Lists contain elements Basic list Operations Creating a List You can…

So uh…. I did this chapter, but I have no notes on it. O WEHL It’s stuff I NO WHEL. will I need the reference only time WILL TEHL.

Null Overview Null Sound Safety – removing null from results and only putting it back if you ask dart to do so. What null means It means something has no value and is preferrable to coming up with your own conventions for “nothing” since it’s already built into dart and everyone understands what it means….

Observations: 4 more to go; I’m so ready to dive into async I can almost type it. You always think these chapters aren’t bad in terms of length but then you outline them and die a little inside. I am beyond ready to be done with this book emotionally and am ready to move on…

Skimming through the chapter before I started it, I can tell this is going to be an EXCELLENT chapter. One observation is that I can SEE the chapter not only giving me the knowledge to work with the tool (Dart in this case) but also how I can use that tool well and most effectively….

AWWWWWHHHHHH YEEAAAA. It’s time to put the gardening stuff down for a couple hours and dig a little deeper into dart! and then I will probably do some net+ studying and then start my ansible projects. But you wont be here for that….anyways….Lets Go! Making Comparisons Booleans are explicit and that’s why we use them…

Commenting Code Heh. From the drop I forget that dart requires a main() function. You’re gonna notice really quickly I’m already somewhat familiar with the language and am going to be doing more involved code demos to get myself back in the flow of programming with dart. To be honest, things probably wont slow down…
