OTC CatchUp #197

Date: 17-08-2024

Duration: 3 hrs 41 mins

Topics Discussed

  • Aryan Pathak told us about the differences between Snaps and Flatpaks in Linux.

  • Dheeraj Lalwani asked us why a server running in a Docker container on an exported port does not work when the user tries connecting to it through the IP 0.0.0.0:8000 from the browser, when he has explicitly allowed any IP address to connect to the server at port 8000.

    • We helped Dheeraj remember that 0.0.0.0 is a wildcard that indicates that any IP address is acceptable, so entering 0.0.0.0:8000 in a browser doesn’t actually point to any IP address, which is why the browser is not able to reach the intended server.

    • Dheeraj also expressed his interest in Docker networking, which is why Harsh Kapadia shared Docker Networking Crash Course and github.com/HarshKapadia2/mac-ip-routing.

  • Aryan Pathak asked about higher education from the context of someone wanting to pursue a Master of Science in Computer Science. Harsh Kapadia, Pranav Dani and Viranchee L answered.

    • How much money is required?

      • Unfortunately tons. Provisions for around a Crore should be made.

      • If they’re taking loans, people usually take ~Rs. 50 Lakh as an education loan.

    • How important is one’s CGPA?

      • Extremely important, especially if one is going to pursue higher education directly after college.

    • Which countries require the GRE?

      • A lot of them.

      • On an average, it takes about three to four months to prepare.

    • Why is USA so popular? What about Germany and Ireland?

      • USA has some of the world’s best universities and a lot of well-paying jobs.

      • The main issue with Germany is the language barrier.

    • How much do research papers matter?

      • A lot, but only good and proper ones. Papers written for the heck of it don’t matter.

    • Can one skip Leetcode if they’re pursuing a Master’s degree?

      • Definitely not. All interviews unfortunately include Leetcode-type questions.

  • Cybersecurity

  • CPU pipeline

    • We discussed the differnces between RISC and CISC architectures.

    • Every instruction in RISC-V is 32 bits long and program counter increments by 4 (bytes) so that it can point to the next instruction.

    • Dheeraj Lalwani asked about the CPU pipeline and how it works. Pranav Dani explained the concept of a pipeline and how each stage and its registers play import part in the pipeline.

    • Pranav Dani shared an online simulator for RISC-V to explain the pipeline stages.

    • We talked about branch prediction and how one would go about implementing it in a pipeline.

Show and Tell

  • Pranav Dani showcased his RISC-V project where he built a 5+ stage pipeline in Verilog.

    • He executed a few programs compiled for RISC-V on his verilog pipeline.

    • The processor in its current form talks directly with the memory over AXI4 protocol, but he plans to add a cache in the future.
