Mobile App Design In Sketch 3: UX and UI Design From ScratchI have recently enrolled in this course, and I can tell you that. It is a fantastic course. This course introduced a really great platform called Sketch, which is a really professional tool for designing logos. Before, I could only play with some basic features on Sketch, and usually spend hours to design a simple logo. This course made me into a pro in Sketch. I love this course so much, and I strongly recommend you buying it!

Today, Apple released the third developer preview of OS X El Capitan, which is another update of bug fixing and performance improvement. And one thing that really surprised me is how the Geekbench performance score went up after the update. Before in OS X Yosemite, the single core score is about 2600, and the multicore score is about 7800. And when I installed OS X El Capitan, the score went up to around 2800 for Single Core, and the score also increased to around 8000 for Multicore. In the second preview of OS X 10.11, the score dropped a bit and the computer kind of slowed down. But when I upgraded to the third preview of OS X El Capitan, there are a lot of bug fixes, and my computer went so much faster. And I'd like to show you the Geekbench score of OS X El Capitan Developer Preview 3. This image is before the the update, it is the second developer preview. Not so high score since I am running on iMac 21.5 inch Mid 2011. And I just recently upgraded my memory from 4 GB to 16 GB, which kind of makes a huge difference. So anyway, here is the Geekbench score of my Mac running that the second preview of 10.11. The image above is the second preview of OS X El Capitan. The image below is the score of the third developer preview of OS X 10.11. I tested three times, and one time, the score went up to 3300 and 8295. But I accidentally quit the app.
Hey guys, I found this awesome Udemy course about hacking. It has a total of 17 hours! This course is really great since it is very specific. For example, it has 7 lectures with specific instructions on setting up the environment. I really love this course and I hope that you can check it out! The instructor of this course is Jerry Canfield and Ermin Kreponic. Here is the link: The Complete Hacking Course: Go From Beginner to Advanced! Here is a preview of this course When I was learning Swift, I get very confused about keywords in front of functions and variables (or constants) like "static", "lazy", "mutating", etc. Well, there is a great thing called the internet, so I searched up and found out not all the definition is very specific and easy to understand. So today, I am going to tell you what does the mutating keyword does in front of a function.
So usually you use the mutating keyword in front of a function in a structure or class. Purpose: Allow this function to change the value of the variables in this structure or class Usage: mutating func (function name) () { } Example: struct myStructure { var myVariableInt: Int = 8 mutating func changeMyVariableInt(newValue: Int) { self.myVariableInt = newValue } } Notices: If you just use a normal function without any keyword in front of it, you will get an error, so the purpose of mutating is allowing the function to change a value in this struct or class. That's all about mutating function If you are using Swift in Xcode to develop an app. And you are using the navigation bar. You might find it difficult to change the bar button. So I got you a solution Imagine that there is a navigation bar, and I want to change it from "Edit" to "Done", and "Done" to "Edit". So I can use the following code to do this import UIKit // Got to import the frameworks first class ViewController: UIViewController { var isEdit: Bool = true // Let's ignore the viewDidLoad function and the memoryDidRecieveWarning function and jump right into the IBAction @IBAction func pressedNavButtonRight(sender: UIBarButtonItem) //Create an IBAction { if isEdit { isEdit = false self.navigationItem.rightBarButtonItem! = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: "pressedNavButtonRight:") // For the title of the function above, set the title to the title you want to, the style is an enum, so you should get automatic suggestions when you type the dot syntax, and I believe there is plain, bordered, done, and something else. For target, write self. For action, inside a pair of quotation marks, write the function you want to call when the user press this button again. In this case, it is pressedNavButtonRight, but you have the add a ":" right after it. } else { isEdit = true self.navigationItem.rightBarButtonItem! = UIBarButtonItem(title: "Edit", style: UIBarButtonItemStyle.Bordered, target: self, action: "pressedNavButtonRight:") } } //Code above For further explanation, please check out the video Hi everyone. I am Ryan Jin. Yesterday I was working on an app and had trouble passing data between view controllers. Today, I found an easy way. If you don't want to watch the forteen-minute-video. I'll just tell you this: You can declare your variable outside your class to allow any file in your project to access it. So you can do //Below this is the code import UIKit var thisIsMyVariable: String? class ViewController: UIViewController { //functions and methods and properties } //Code end, above this is the code And this allows other files to access it? For further information, please check out this video Hello everyone. These days I am learning computer science. And this is a great lecture by computer science a found on Youtube, well, you can also find it on iTunes U in iTunes. It is lecture CS50 by Harvard University. Here is the link
I don't know how copyrights work and things like that. Just to note, I just want to share things I like and found interested in. This source is by Harvard University, not me. So I think I don't pay any responsibility by sharing it. Right? Prime Factorization is an important thing in Math. Today I am going to share my C program that is for prime factorization. Download the following .exec file, run it. It is an Application that does Prime Factorization.
