Remembering Things With Computers

So we’ve learned about binary and boolean operations along with logic gates. None of these, particularly logic gates, can do the second most important thing necessary for computation.

That is the ability to remember.

Phabstractic: Self-Sorting List Data Type

Self-sorting lists can be very handy. For instance, we could easily implement a priority queue by utilizing a sorted list, and that’s something we’re going to do, simply using the comparison method on competing priorities. Self-sorting arrays make putting everything in order in a messaging queue fairly simple.

Tomodachi Happiness, Episode 4

It was a nice day the other day in Chrakia (my town), so people went out and had a barbecue! That was pretty cool, but the thing I thought was the funniest was that KadarMan (my look alike) had to stand on a bench in order to participate.

Leaves and Houses, Episode 4

Kadaria is the name of my town, and I’m the Mayor Ashrwolf! I play the game pretty casually, I don’t fast-forward time or anything. I haven’t unlocked the last largest department store yet, as you’ll see below, but I’m working on it… kinda.

The Code of Gray

Have you ever heard of anything called a gray code? If you aren’t a programmer or a computer enthusiast (or for that matter an electrical engineer), then probably not. It kind of sounds like a movie doesn’t it?

Flower Town Updates

When you meet people they come in and water your plant, making it grow, and then they share their plants with yours to get seeds to make more plants. I actually have become a master gardener already

Golden Girls Trivia

Okay, the question of the day – What was the name of the comic strip shared by Rose featuring the joke between the two crows? Bonus if you can say what the crows said.

Phabstractic: Restricted Lists Data Types

Lists are very important pieces of software engineering and implementation. With a restrictions predicate we are able to ensure variables in PHP are specific types. If we combine these two things we get a restricted list.

Pokémon GO Round Up 9

I want to try to see if I can take over the gym with like a 2000 combat point Snorlax. That’d be awesome. I thought it’d be kind of funny if I powered up a Rattata like super high and took over the gym with that. I might do that, or a Pidgey.

Octal Arithmetic

For now, this should have you calculating octal ’til the cows come home. This is an important skill when calculating addresses in memory.

Poochie Cures Cancer HD: Shocking Proportions!

“After a slimy piece of something gooey and alive jerked around and then died inside the metal arm, she got up and wiped her hand across her forehead, “See that wasn’t so hard was it? You look like you kind of liked it.”

Hexadecimal Arithmetic

For now, this should have you calculating hexadecimal ’til the cows come home. This is an important skill when calculating addresses in memory. Memory locations are often referred to in hexadecimal in order to shorten their length.

Phabstractic: Stack Data Type

“In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed.”

Phabstractic: Queue Data Type

Queues are very important pieces of code.  They are used in numerous many places including web services, transactions, and multi-process operating systems.

Binary Math

As you can see binary arithmetic calculations are easy-peesy. I mean you only have to digits to worry about: 1 and 0. I remember learning my multiplication tables and 7 was the hardest for me to remember. I was never good at 7 until I was an adult. But, as a kid, I thought I had to know it all now… I couldn’t imagine myself as an adult.

Pokémon GO Round Up 8

But in other news that I found more interesting, I evolved a Venonat! I hadn’t realized that I hadn’t ever done that before, and today I noticed I had enough candies. I was surprised with the result.

Phabstractic: List Data Types

Lists are very important abstract data types, and are used in many many different applications. Stacks are often used with programming languages, and in fact some programming languages depend entirely on a stack, such as Postscript.

Binary Negative Space

The four most popular methods for encoding (representing) negative binary numbers are known as “sign and magnitude”, “ones’ complement”, “two’s complement”, and “Excess-K”. There are alternative methods as well that aren’t as popular such as negative binary where the number base itself is actually negative (being negative 2).

Magic Hexadecimal and High Octane Octal

That’s all there is to hexadecimal and octal. As you can see, hopefully, it’s not too complicated and is quite a bit like binary. Hexadecimal and octal were introduced to me when I was editing data files in a text editor that displayed the hexadecimal values of each byte as well. It was a pretty useful program.

Phabstractic: Restricted Set Data Type

By combining the restrictions predicate and the set we are able to configure a Set that only holds certain objects and types. This means I can make a set of integers, or a set of nodes, or a set of whatever without fear that the set will hold anything else.
