I chatted with her during spring break

My plan for spring break is nothing. I try to rest myself and recover. The only target for this spring break is to painlessly develop a routine and think as much as possible. I lost the routine of learning English at the beginning of this semester because of tiring school work and doing my own project. However, my listening and speaking level is still not enough for me to fluently speak and unconsciously listen to others. The habit I try to establish is to watch a English new and learn 30-50 vocabularies everyday. Apart from that, the only other thing I look forward to is to have a zoom call with my high-school classmate who's photograph I posted earlier. I hope I can do things more efficiently and persistently after the spring break.

Don't spend more than 30 mins a day on LabSim

I have never thought that passing MO-100 is an achievement or milestone. Finishing all the practice and passing the exam is a necessity. However, the pathway to it is not easy. Learning how to use tools on Microsoft Word from the tutorial is tedious but important. In order to finish the boring parts as soon as possible, I will skip the opening and ending of the tutorial videos and only watch the useful parts. Also, I have never looked at the text instructions. Then, I will try my best to finish the practices quickly and get away from the LabSim. If I don't want to do the LabSim tasks on a day, I will leave them for another day.

5 minutes promotional brochure

I can't believe that it can be so easy to make a good-looking flyer. When I was studying at high school, I took nearly a day to make a flyer for the promotion of the student union with photoshop because no one tell me the Word could do that. Photoshop was complicated and so I had to watch a lot of tutorials on YouTube, learning about it. On the contrary, the Word contains tremendous beautiful templates of a flyer and you don't have to build a new one from the beginning. If I was given one more chance to make a flyer, I would definitely use the Word to do it. What I need to do to make a flyer is to click on a flyer template matched with the theme color and type the words. Then, that's it.

How to finish your assignments faster

I can say "ctrl + F" is one of my favorite hot key on computer. Not only can we navigating in the word document but also in a browser. Searching some specific content in dozens of pages, I only have to click on "ctrl + F" and navigate to the page related to the keyword. This makes me look up somethings quickly especially when I'm doing a online assignment. For example, when I'm doing the Anthropology's MC questions, I can look up the keyword from the question and soon find the correct answer. Just make use of the "ctrl + F"! Work smartly and be lazy!

Minecraft Server

I am making a RPG Minecraft server with my friend and thus I have to host a server. I bought a computer for the server at my Hong Kong's home, connecting to my wi-fi. Then I downloaded the server kit for Minecraft and set it up. At the moment, a Minecraft server was done. Players could connect to my server and played ,but it was only available for those connected to my home wi-fi. That sounded like a joke for a server because we didn't even have to host a server if we were stick together. Therefore, I searched the tutorial of publishing a server on the Internet and made ports for TCP and UDP accordingly for the sake of posting my server online. Honestly, I didn't really know what they were until I saw "2.5.5 Internet Protocol Facts". I understand that through Transmission Control Protocol, players can correctly download files in high speed and connect to my server.

Send me a lossless photo please

Recently, a girl sent me her selfie from Instagram inbox and I found it pretty fuzzy. Then, I saved the photo and looked at the detail of the picture, figuring out that the size of it was only 274.02KB. Usually, a photo taken from a phone is at least 1MB above. I know that she is not using the Nokia 3310, a old generation phone, so what is the reason of the blurred selfie? I solved the doubt by reading file compression facts from chapter 1.1.14, realizing that it is a lossy file type, the JPG. It is believed that the compression algorithm in Instagram heavily alters the data and thus the selfie loses more than 70% of the resolution. The best solution would be asking her to resend it through Dropbox in order not to compress the picture or seeing the real person.

PS: the photo isn't authorized by the girl.

The Usages of Big Data

Comparing those three sources related to the usage of big data, intuitively, I can see the academic source is longest and comprehensive, non-academic primary source is medium and non-academic secondary source is the shortest and abridged. Academic source tells the usage of big data with the topic definition, detailed explanations and test results. Non-academic primary source tells the usage of big data with it's mechanism. "The more unrelated the datasets we are using in a model, the more likely they are to reveal unexpected correlations between customers’ behaviors in different settings." Non-academic secondary source tells the usage of big data without explanation. "Some hospitals use big data to detect blood infections in premature babies."

First Impression of IS101

I think the IS101 course is learning something in the real meaning of "practical" unlike History or subjects that you may never use it in workplace. At least, you won't tell a history story to your colleagues once a week or put a "history expert" into your resume, right? On the other side, after this course, I will tell every company that I am a Microsoft Office Specialist or Expert (Hope that I can get an expert certificate.) and it is possibly that I will use Microsoft Office frequently in my work.
