"JavaScript” is Oracle’s Trademark

"JavaScript” is Oracle’s Trademark I didn’t know “JavaScript” is Oracle’s trademark. https://www.j-platpat.inpit.go.jp/c1800/TR/JP-1996-059907/AF0DA4A53C9CFB5A3C177ADE500BC9DBDAB83703CA8E1E4E609D21AC90C803A4/40/ja There are variety of programming languages which are derived from JavaScript by big IT companies. I didn’t know why they don’t use raw JavaScript, but I found they don’t want to use Oracle’s trademark. In addition, I found this article, “”Dear Oracle, Please Release the JavaScript Trademark. https://tinyclouds.org/trademark JavaScript is very useful for indivisuals, but “JavaScript” is not useful for business.

Nikkei index price analysis with Python

2022/1/16. Nikkei index price analysis with Python I wrote some Python codes for analysis about Nikkei index price. The time period is 2021/10 - 2021/12, and I uses Nikkei index price, Volume and Selling Volume as parameters. The codes are on GitHub. https://github.com/Kouhei-Takagi/NIKKEI-Price PPDAC is important for this task, PPDAC is consisted from Problem, Plan, Data, Analysis and Conclusion. {Ploblem} I want to know what happened about movement of Nikkei index price. {Plan} Can I know it from some parameters? {Data} I collected data with some Python codes. {Analysis} I visualized the data and thought about it. 2021/10 2021/11 2021/12 These figures show that (A) Volume and Selling Volume had strong relationships, and (B) perhaps Nikkei index price downed after 5 -10 day later when Selling Volume increased. {Conclusion} Not secret. From thinking about above (A) and (B), Nikkei index price may be difficult to fall down or raise up. I thought

Python coding

I did Python coding and wrote one article on Qiita. https://qiita.com/K-TKG/items/cb198a0f63f98003d961 This is written in Japanese, so that perhaps you are not able to read it... Parts of my code are below... https://github.com/Kouhei-Takagi/NIKKEI-Price

Python

2021/12/19. Python Recently, I am writing Python code, and uploaded on my Github page. https://github.com/Kouhei-Takagi I want to invest with Python. Python can help to analyze about NIKKEI225 by visualizing. Below figures are some of the result. Python is very useful tool!

The Python

2021/5/1. The Python I am learning about Python language with Udemy. Dr.Angel’s “100 days of coding” is best course I have met. Python language is just like user side computer programming language. It is very useful for computer users. This means that Python language will be defect standard in programming languages. There are various computer OS, and Python will be language across those OSs. Python is powerful language. For example, I use Python library PyPDF2 for combining PDF. This library saves money for me to buy additional PDF readers’ function. The function costs $15per a month. There are lots of IDE(App for writing codes), and I am using VSCode on Windows. VSCode is free IDE for private development. Very useful, it is. If someone wants to get new skill, I recommend learning Python. And how I learn Python are below. (1)Watching Udemy courses. (2)Reading books. (3)Copying codes from Udemy courses and books. (4)Additionally, reading magazines about Python. (5)Coding what I w

The PHP language

2020/6/14. The PHP language Recently, I am learning PHP language. PHP language is server-side language, and it is useful for web watching. I wrote below code for web-watching to take the Mensa Japan exam. (I am already Mensa member.)(And I don’t know this code will work well.) Below code notifies with LINE app, so if you want to use it, you have to get permission from LINE development. And you need to set some settings on your smartphone. This is only test code, and if you want to use this code, you need some knowledge about Information technology. And if you can use Linux crontab, this code runs every time. I know you don’t need to take Mensa Japan exam. This is just sample for getting a ticket which is difficult to get online. First, I tried to use e-mail, but the e-mail’s security setting is too difficult. So, I changed to use LINE app. I took few weeks for writing below code, programming is so hard… Of course it is fun. I started learning pr
