Fixing Common Pitfalls of Codemods

2 Shares

So far the codemods that Juntao Qiu has described are fascinating, but rather straightforward. Real codebases offer more challenges. In this installment, he goes into how to tackle more complicated cases by composing codemods.

Ackchyually, IIRC without radioactive decay our planet would have cooled down below life-sustaining temperatures long before any complex life-forms would have had the chance to evolve

https://en.wikipedia.org/wiki/Earth%27s_internal_heat_budget#Heat_and_early_estimate_of_Earth's_age

The part where it took 800 million years of before life evolved something to do with all that toxic oxygen that those damn cyanobacteria were producing was a particularly difficult hurdle.

Funny how that one never pops up in discussions of "great filters" - the Sun is 4.6 billion years, will burn out in another 5. Life spent almost 10% of that time repeatedly almost killing itself before some life form figured out how to use oxygen. What if that's the part where we got lucky, and that on average most habitable planets get stuck in this self-destructive oxygen cycle?

The sun heats the earth. Yes, the core would have cooled down faster without radioactive decay. But it's not clear how that would affect surface temperatures or what effect that would have on life on earth.

It's true that the sun heats *the surface* of the earth and completely dominates the energy input there. However, we capture that heat due to having an atmosphere. Part of what maintains the atmosphere (over millions of years) is volcanic activity. Volcanic activity exists due to having a molten core. Also, life seems to have started at geothermal vents. So alltogether life would be radically different at the very least, and likely way more limited in its opportunities to evolve.

Lab: Level-1 and Level-2 IS-IS Routing

1 Share

One of the recipes for easy IS-IS deployments claims that you should use only level-2 routing (although most vendors enable level-1 and level-2 routing by default).

What does that mean, and why does it matter? You’ll find the answers in the Optimize Simple IS-IS Deployments lab exercise.

netlab: Multi-Site VLANs

1 Share

Imagine you want to create a simple multi-site network with netlab:

  • The lab should have two sites (A and B).
  • Each site has a layer-3 switch, a single VLAN (VLAN 100), and two hosts connected to that VLAN.
  • As you don’t believe in the magic powers of stretched VLANs, you have a layer-3 (IPv4) link between sites.
