  • Mohit Gangwani asked about how asynchronous operations work in JavaScript if it is single-threaded.

  • Siddharth Bhatia shared An open letter to our community, a blog by Unity talking about them going back on their pricing changes after wide dissent.

    • We all were glad that a company finally listened to their user base.

    • We also talked about how Unity has lost the trust of their developer users because everyone will keep in the back of their minds how companies can very easily turn on their users. Some argued that this might not be the case as people might forget about it.

  • Anushka Bhagchandani shared her experience of working at Myntra.

    • She discussed Appliqué, which is an open-source design system for enterprise applications.

  • Harsh Kapadia discussed the assignment of his University of Operating System lecture, in which he has to capture keystrokes using kernel.

    • Anil Harwani talked about how a Keylogger works. It is basically installing a driver in the system so that it captures the strokes and sends them to a server or save them locally.

      • He talked about how Zero Click Malware and Rootkit work.

      • Continuing this, he told us about the widespread nature of an incredibly malicious worm called Stuxnet that was widespread and mostly affected Iran’s nuclear program.

      • He also talked about how Kernel Obejcts are needed to be signed.

        • He said that signing is important because no one other than an authorized user should be able to insert/install and use a kernel module/driver, as not following this could cause security issues.

  • Harsh Kapadia talked about his learnings about different/equivalent Instruction Set Architectures (ISAs) like x86, x86_64, amd64, IA64, etc.

    • Anil Harwani talked about IA64, an old ISA from Intel that was seen in their processor Itanium. It was supposed to be the alternative to amd64, but it never caught any traction.

    • Anil Harwani gave him a brief about the different levels of abstraction that are developed on a computer system and how he can think of abstractions as a layer to make things easier to understand. To understand abstractions better, Anil gave examples of various abstractions by including real-life examples.

  • Siddharth Bhatia and Chirag Bachani asked for suggestions to participate in a Hackathon.
