Our Mission: At Guanghua Computer Club, we hope to promote interest in computers, technology, and mathematics among the youth of the Greater-Philadelphia Area. Our main missions are to increase participation among students of all ages (Elementary to High School) in meaningful computer explorations and to extend the knowledge of those with experience in computer science, through learning and discovery. Throughout the year, we plan to invite experts, professors, and workers to show how knowledge of these fields can have real life impacts and applications,. Already, we have generously received mentorship from adults on the Advisory Board. Dr. Thomas Yu is a Math professor at the University of Drexel, who has previously studied computer science and was able to join us for the first member meeting. Dr. Derek Wang, CEO of Bell Curve Capital, came to our first meeting to discuss a few of his interests and goals for us in computer science and programming languages. Principal of Guanghua, Dr. You Heng, and Jennifer Yuan, the founder of our club, additionally offered invaluable assistance. Aside from speakers, the club will give students a chance to create, innovate, and lead through experienc- es with computers. Activities like Hour/Week of Code, in December, will offer members these opportunities to learn and develop their pro- gramming skills. Members and officers will have the chance to share and discuss topics they are interested to others through presentations and articles in this newsletter. Our club strives to unearth for its members aspects of the wide- range of topics in Computer Science; we hope to have you or your child join us in doing so. Sincerely, Ethan Wang

Newsletter Editor Google Ethan Wang By Ethan Wang

• Lead Editor for Newsletter New competition has arisen for Apple and other Android phones. One year after releasing the first Google phone, the Pixel, Google has released the revamped

• AP Computer Science Review Team Pixel 2. Pixel 2 is just one of the intriguing new technology released by Google, with others including the , Google Home, (camera), Google • R Team (laptop), and (Video Stream device). With these new additions, Google is on its way to becoming a household name for technological hardware, not just elite • 11th Grade online services. For those unfamiliar with this phone, the 2 is worth a look, if not a purchase. Some of Google Pixel’s features are unprecedented, utilizing concepts • 16 Years Old like and artificial intelligence in the cell phone world. There are two phones that were released by Google, the Pixel 2 and Pixel 2XL. The differences are that the Pixel 2 has a five-inch screen, smaller battery, and larger bezels, while the Pixel 2XL has a six inch screen, larger battery, and shorter bezels. In

terms of function, they are identical. Obviously, people are curious as to how the camera of the Pixel 2 compares to other phones, like the iPhone 8 and Galaxy S8. According to DxOfMark analysis of cam- era quality, the Pixel 2 has a higher rated camera than every other smartphone, boast- ing a rating of 98, compared to a rating of 94 from the iPhone 8 plus. Features like im- age stabilization, which adjusts to camera movement, and the use of six lenses that move to focus and create an unblemished picture, contribute to this exceptional cam- era. The camera also offers portrait and HDR modes, like the iPhone 8. You won’t need to worry about conserving your usage with this excellent cam- era. That’s because the Pixel 2 has unlimited photo storage using . Tak- ing photos with a phone just received a major upgrade. Much like in Apple’s Siri, Google phone users now have their own personal assistant on their phone, called the , which make plans, give directions, and give information. Another feature automatically interprets and displays any song that is playing at any time, virtually rendering apps like Shazam useless. In my opinion, object recognition is the coolest feature of the Pixel 2. The Sophia Hu conveys to users information about objects or places taken through the camera.

Google Lens marks just the beginning of Artificial Intelligence in society, but it sure- ly opens up excitement about the future possibilities of these technologies. • 6th Grade It costs $649 and $749 for the 64 and 128 GB versions of the Pixel 2 and $100 dollars more for the Pixel 2XL, deserving prices for its original and unique features. PIx- el 2, full of interesting and practical software, deserves consideration among the best of phones.

Who did it? By Sophia Hu

Technology has changed a lot over the years, but hacking has always been around. Starting in 1878, the first hackers were just a bunch of teenager boys fooling around disconnecting calls and misdirecting calls. And by the 1960s, the first computer hack started. On October 5th, around 6:00PM, the White House’s Chief of Staff John Kelly was hacked. For months, he has been experiencing glitches on his phone. Unfortunately, it is unclear how and where it started. What’s even worse was that this was John Kelly’s personal phone, not a work phone or computer. This reminds us that powerful- government people have a high risk when using consumer things. .

Can Robots Argue? Richard Wang By Richard Wang Up until pretty recently, humans have have been better at performing most • Editor for the weekly newsletter tasks compared to a robot. Will that remain the case for much longer? Now, robots are capable of much more tasks than humans. They can compile data, they can evalu- • Posts on the blog ate data, and much more. Now, many computers are smarter than humans, but they • 13 Years Old haven’t yet been able to impersonate a human or their emotions. Before, one task computers struggled at was getting right what pronoun • 8th Grade went with which normal noun. For example, if you told a computer, “I like Gordon Ramsay’s food, bring up one of his recipes,” the computer wouldn’t be able to give you one of his recipes because it doesn’t know what the word “he” is referring to. Nevertheless, robots now have the ability to deduce what a pronoun is referring to. Now, you might be scared of losing an argument to a robot right? Well, you don’t have to worry yet. Most robots made to argue will mainly argue about why something wouldn’t work or doesn’t exist. Basically, they would present counter- arguments which would make you rethink your case and present you to the other side of the argument. This could be very useful because it could tell people what might be wrong and cause them to make better decisions for the long run. In conclusion, although computers never have been able to argue, they might be able to now. Nevertheless, these robots wouldn’t argue with people 1 on 1. Rather, they would present the user with counter-arguments on why something might not work. So even though they may not be able to scream at you for doing something wrong just yet, they may be close.

Andrew Chen Apple IOS 11.01

• Editor for the weekly newsletter By Andrew Chen You are on your phone one day. Suddenly, Apple asks you to update to IOS • 13 Years Old 11. How do you know if this will harm your phone, or be beneficial? Well, there are a few things you need to know before using it. • 8th Grade First, the control center is now different than before. You have to swipe up and it will show you the options. The two bars of brightness and sound show up when you swipe up to change either of them. Then, there is a radar looking icon. This is Airdrop, which you can use to send to other Apple products without having to have a USB or email. You can also now record your screen, there is a small circle, click on it and you will start recording. Click on it again, and you will stop recording

Next, Apple also changed , Apple’s IM center. You can now send money through messages, by linking you debit/credit card to your Apple ID. This is very useful. Say if you owe someone money, you can open messages, click on the Ap- ple Pay icon, and enter your Apple ID password or touch ID, and this sends the money to the other person’s bank account. All the other person needs to do to complete the transaction is to enter their Apple ID or touch ID and it’s all good to go. Lastly, there is a new bult in app called Files. This is basically File Explorer on a Windows Desktop/Laptop or Finder on Mac/Macintosh HD. This allows you to go into your iPad/iPhone/iPod’s system files and change them (not advised). You can also use this to go to remote file servers, such as iCloud, Dropbox, Etc. By using these techniques, I hope that you can use IOS 11 accordingly and not have to search online to use your brand new updated phone. Bring in your solutions to the next meeting for prizes!
