How to setup WASI SDK on Linux?

Setting up the WASI SDK is the simplest on Linux like Ubuntu. You just need to run few lines of commands. That's it!

Open the Linux terminal and go to a directory where you can download the payload. Usually, I prefer downloading the stuffs in /home directory but it's up to you.

Run these commands to download and install the WASI SDK

curl -O -L https://github.com/WebAssembly/wasi-sdk/releases/download/wasi-sdk-20/wasi-sdk_20.0_amd64.deb
sudo dpkg -i wasi-sdk_20.0_amd64.deb
export PATH=/opt/wasi-sdk/bin:$PATH
export CC=/opt/wasi-sdk/bin/clang
export CXX=/opt/wasi-sdk/bin/clang++

Now you are ready to use WASI SDK which you can check by this command, clang -v. If it prints the version info then all is well.

Unlock protected blocks in Siemens SIMATIC Step 7

Recently I'd been called by Hindalco's Fabrication Plant division to unlock the protected blocks in Siemens SIMATIC Step 7. They were in need to unlock those blocks since an year because of 1 million Rupees of loss per month. They want to re-program those blocks but it was locked by the man who'd done the setup. From the people working in that department, I came to know that they were trying to call that man (someone from Italy) right here but he's not coming. Actually, what he'd done was that he'd locked some of the blocks and deleted the source file. And Siemens didn't provide any feature to unlock. Department people also told me that even the people working in Siemens don't know how to do it. Being a software engineer I know that any thing can be reverse engineered. So I took up the challenge. How did I unlocked the blocks? The first thing I'd done was searched about this software at Google and read about what is this software all about. Aft...

Launching a Jupyter Notebook with TensorFlow using Docker

This article will walk you through setting up a Jupyter Notebook environment with TensorFlow pre-installed using Docker. Docker allows you to run isolated containerized applications, providing a consistent environment regardless of your underlying operating system. Prerequisites: Docker: Ensure you have Docker installed and running on your system. You can download and install it from the official Docker website ( https://www.docker.com/ ). Steps: Start Docker: Open your Docker application (Docker Desktop for Windows/macOS or the command line if using Linux). Run the Jupyter Notebook container: For macOS/Linux: Open your terminal application and run the following command: docker run -it --rm -p 8888:8888 -v "${PWD}":/home/jovyan/work jupyter/tensorflow-notebook For Windows: Open your Command Prompt application and run the following command: docker run -it --rm -p 8888:8888 -v "%CD%":/home/jovyan/work jupyter/tensorflow-notebook Explanation of the command flags: -...

JS: The complete code example of Crypto.js (DES)

For one of the project I was trying to use crypto.js but I found that the Quick-start Guide have some deficiency in terms of library usage. So I am writing it here as a useful note for memory recap. <script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/tripledes.js"></script> <script> var encrypted = CryptoJS.DES.encrypt("The secret message", "secret_key"); var e_msg = encrypted.toString(); console.log(e_msg); var decrypted = CryptoJS.DES.decrypt(e_msg, "secret_key"); var d_msg = decrypted.toString(CryptoJS.enc.Utf8); console.log(d_msg); </script>
