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 entering0.0.0.0:8000
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.

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.
