You can see I change the Hello Word! text into GRADIENT COLORS. I add this source line of code:

This tutorial is about how to create a button with a good effect. First, the HTML 5 source code comes with the button using the div tag:

<div class="button effect">This is a issue!</div>

The next step is to use a CSS format to add the font style and create these settings: button settings for after,… Continue Reading Test with an button effect.

Collaboratory, or “Colab” for short, is a product from Google Research. Colab allows anybody to write and execute arbitrary python code through the browser and is especially well suited to machine learning, data analysis, and education. More technically, Colab is a hosted Jupyter notebook service that requires no setup to… Continue Reading New Colab from Google .

You can use WebExtensions API to extend the browser’s built-in developer tools. Today I will show you how to test the web extensions-examples from GitHub.

Open a new spreadsheet with a Sheet named Sheet3, then a new script. This will require a new project. Also, you can run it with an old project. Use this function to add a blue color on each empty cell selected by your mouse in the Sheet3. You can see… Continue Reading Google Apps Script – get tasks – part 027.

This tutorial solves this issue about how to parse a text document open by an Id and put the output into a Spreadsheet. The input text from the text document must have four signed number delimited with a comma like as regular expression variable named r from source code:

  var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var doc = DocumentApp.openById('123xyzTimp\oOBb|hH...');
  var text = doc.getBody().getText();
  var result = [];
  var r = /[+-]?\d+,[+-]?\d+,[+-]?\d+,[+-]?\d+/g
  while ((res = r.exec(text)) !== null) {
    //result.push([res[0]].toString());
    result.push([res[0]].toString().split(","));
    Logger.log(result);
    }
 
  //ss.getRange(row, column, numRows, numColumns)
  ss.getRange(ss.getLastRow() + 1, 1, result.length, 4).setValues(result);

The source code is easy to understand. This source code shows you how you can use a macro for print. The base of this source code use INT 0x80 with a rax register for many functions like… Continue Reading Programming with FASM – the format ELF executable – part 006 .

Let’s write into a text file named new_file.txt with an assembler program. First, you need to create this text file using the command touch.
