SD-WAN Reality Gap
Here’s some feedback I got from a subscriber who got pulled into an SD-WAN project:
I realized (thanks to you) that it’s really important to understand the basics of how things work. It helped me for example at my work when my boss came with the idea “we’ll start selling SD-WAN and this is the customer wish list”. Looked like business-as-usual until I realized I’ve never seen so big a difference between reality, customer wishes and what was promised to customer by sales guys I never met. And the networking engineers are supposed to save the day afterwards…
How did your first SD-WAN deployment go? Please write a comment!
Neural Ordinary Differential Equations
Neural ordinary differential equations Chen et al., NeurIPS’18
‘Neural Ordinary Differential Equations’ won a best paper award at NeurIPS last month. It’s not an easy piece (at least not for me!), but in the spirit of ‘deliberate practice’ that doesn’t mean there isn’t something to be gained from trying to understand as much as possible.
In addition to the paper itself, I found the following additional resources to be helpful:
- Thread on HN
- Kevin Gibson’s blog post on the paper
- Branislav Holländer’s post on ‘Towards Data Science
- Adam Kosiorek’s introduction to normalizing flows (as linked from the previous post)
- High level summary in MIT TR’s ‘The Algorithm’ newsletter
Neural networks as differential equations
Consider a multi-layered neural network. We have an input layer and an output layer, and inbetween them, some number of hidden layers. As an input feeds forward through the network, it is progressively transformed, one layer at a time, from the input to the ultimate output. Each network layer is a step on that journey. If we take a small number of big steps, we end up with a rough approximation to the true transformation function we’d like to learn. If we take a much Continue reading
Network Lab Base
Most of the labs I build are for learning purposes and I find that I burn a lot of time doing boilerplate tasks and not actually working on the feature(s) im trying to test. I wanted to build a lab where I could chop and change device types from the same vendor ie: Juniper vSRX and vMX...Network Lab Base

MySQL High Availability Framework Explained – Part II
In Part I, we introduced a High Availability (HA) framework for MySQL hosting and discussed various components and their functionality. Now in Part II, we will discuss the details of MySQL semisynchronous replication and the related configuration settings that help us ensure redundancy and consistency of the data in our HA setup. Make sure to check back in for Part III where we will review various failure scenarios that could arise and the way the framework responds and recovers from these conditions. What is MySQL Semisynchronous Replication? Simply put, in a MySQL semisynchronous replication configuration, the master commits transactions to the storage engine only after receiving acknowledgement from at least one of the slaves. The slaves would provide acknowledgement only after the events are received and copied to the relay logs and also flushed to the disk. This guarantees that for all transactions committed and returned to the client, the data exists on at least 2 nodes. The term ‘semi’ in semisynchronous (replication) is due to the fact that the master commits the transactions once the events are received and flushed to relay log, but not necessarily committed to the data files on the slave. This is in contrast to Continue readingChiplets: The Way to Beat Moore’s Law?

Slow MySQL Start Time in GTID mode? Binary Log File Size May Be The Issue
Have you been experiencing slow MySQL startup times in GTID mode? We recently ran into this issue on one of our MySQL hosting deployments and set out to solve the problem. In this blog, we break down the issue that could be slowing down your MySQL restart times, how to debug for your deployment, and what you can do to decrease your start time and improve your understanding of GTID-based replication.
