At times you may come across some old or legacy kernel source-code which could be something you stumbled across online open-source code or it could be your organization proprietary code…
Usually as a part of network software development you do socket programming. But this is typically done in user-space, where the user-space socket APIs takes the instructions (via socket API…
A GPS receiver uses satellites to pinpoint locations, so as long as you have a GPS receiver and a clear view of the sky, you'll never be lost again. So…
Every VPN stack is architecture is done in a specific way to accomplish fundamental VPN specifications, requirements and goals. As a part of VPN Network stack architecture quite often we…
When you architect and implement a VPN deployment as a part of standalone setup or leveraging VPN technologies as one of your building blocks of your SD-WAN product architecture, one…
Many viewers and even sometimes my students ask me how I can become a kernel programmer or just device driver developer and so on. So here is my YouTube video…
If you allocate any global variables and when you access them (i.e read or write) at different parts of the code you are supposed to use locks such as Spinlocks,…
If you are a student you may come across a term called structured programming. Which actually means you write a smooth flow of code and whenever required you steer the…
When you learn programming usually you learn about various programming constructs. One of them is about calling APIs (functions) recursively. Recursive function calling is quite common in situations such as…
