  • I have a theory that CPUs could be faster if they were built around memory s are CPUs limited by Memory Bandwidth and how to calculate if they are?
    2) Playing with a discrete simulation engine like SimPy and characterizing what those latency/bandwidth tradeoffs look like. Source: about 1 year ago
  • Does anyone have any good sources on the way to code a line balancing simulation using Python?
    Do you want to do discrete event simulation? Then I suggest you look into SimPy. Source: about 2 years ago
  • IoT simulation for a total beginner?
    I can recommend using simpy, I used it myself for similar purpose and it is more than enough. Source: over 2 years ago
  • Discrete event simulation
    Check out simpy. It's pretty easy to pick up and get going after reading the docs and samples. Source: over 2 years ago
  • Traffic modeling
    Has anyone tried to do traffic modeling with https://simpy.readthedocs.io/en/latest/. Source: almost 3 years ago

  • Bug Bounty Hunting 101: An Introduction for Beginners
    Practice: Set up simple networking labs using tools like Cisco Packet Tracer or GNS3. - Source: dev.to / 3 days ago
  • Where do I go from here?
    If you mean a Cisco 2950, I guess you want to learn Networking. So a good place to start is to run GNS3 (https://gns3.com). You can download a VM image and run that, that's what I do. GNS3 is a great learning tool and you can use both real (your 2950) and virtual devices to make networks. Source: 7 months ago
  • Exploiting Wpa3
    GNS3 is the software your looking for it can be found here https://gns3.com let me know if you could use some resources on it. Source: 11 months ago
  • What skills are great to learn in a home lab for a beginner in IT ?
    GNS3 is a network device emulator, and more than a few devices requires lots of CPU and RAM resources. You need to pay for a licence for each device you want to emulate. Source: over 1 year ago
