Zettelkästen? | Hacker News
Here’s a LessWrong post that describes it (including the insight “I honestly didn’t think Zettelkasten sounded like a good idea before I tried it” which I also felt).

yeah doesn't sound like a good idea to me either. idk

CppCon 2015: Chandler Carruth "Tuning C++: Benchmarks, and CPUs, and Compilers! Oh My!" - YouTube
- very basics of benchmarking
- Q: why does preemptive reserve speed up push_back by 10x?
- favoriate tool is Linux perf
- callgraph profiling
- important option: -fomit-frame-pointer
- perf has nice interface ('a' = "annotate") for reading assembly (good display of branches/jumps)
- A: optimized to no-op
- how to turn off optimizer
- profilers aren't infallible. a lot of the time samples are misattributed to neighboring ops
- fast mod example
- branch prediction hints (#define UNLIKELY(x), __builtin_expected, etc)

Accessibility - CFPB Design Manual
Alt tags are what a screen reader will say instead of the image. This is important for not only web materials, but charts that are in pdfs and charts that are placed as images into word documents.

[1901.08113] Unveiling the potential of Graph Neural Networks for network modeling and optimization in SDN
"In this paper we propose a novel Graph Neural Network (GNN) model able to understand the complex relationship between topology, routing and input traffic to produce accurate estimates of the per-source/destination pair mean delay and jitter. GNN are tailored to learn and model information structured as graphs and as a result, our model is able to generalize over arbitrary topologies, routing schemes and variable traffic intensity."
