Since 1856, we know there’s a climate issue. Now, we are almost 100% sure it is human-caused. And research – from chemistry to economics - provides solutions. Why don’t we act? Too many behave like Phileas Fogg and burn all resources just to win the race. sustainableswitzerland.ch/themendossier/…
The amazing educator and researcher Jim Kurose explains the Internet in five levels. I had a blast watching him talk with the 8-year-old, and participating in the final level!
The internet is the most technically complex system humanity has ever built. Jim Kurose, Professor at UMass Amherst, has been challenged to explain the internet to 5 different people; a child, a teen, a college student, a grad student, and an expert.
A new AWS whitepaper covering Nitro - "The Security Design of the AWS Nitro System". Super interesting deep dive into virtualization and the AWS approach to security. HTML: docs.aws.amazon.com/whitepapers/la… PDF: docs.aws.amazon.com/pdfs/whitepape…
How Can Open Source Help Fight Climate Change? thenewstack.io/how-can-open-s… @thenewstack @LFE_Foundation gathers 59 members carrying over 18 #OSS projects supporting #climate change #fighting. Hard to believe that persuading decision-makers is a #challenge in front of this urgency
Current CO2 reductions lead to 2.7°C global temp. rise. We urgently need to do better! @CDP #ClimateAction cdp.net/en/research/gl…
4PM today. A big part of this I'm going to get into why cryptography on its own isn't always sufficient, and how to think about building and operating systems with data security and privacy requirements. It'll be archived, but come live for Q&A!
I'm going to to a more interactive livestream version of my reinforce talk on twitch.tv/colmmacc tomorrow - 4PM Pacific time - it's all about how AWS, our customers, and others, can build and operate systems without having access to customer data.
The #DNS has more than two hundred RFCs with more than 3,500 pages total. Where should you begin? Here: blog.apnic.net/2022/07/29/add…
Students often ask for a map of the Internet infrastructure. There is no official map, but @TeleGeography maps are one of the bests publicly available
Our 2022 Global Internet Map tracks global capacity, traffic, and pricing data. Users can also peruse the fan-favorite cloud infrastructure section, which tracks the industry's major cloud providers. Take a closer look here: hubs.ly/Q01hMZHj0
Too many studies that apply machine learning to science & medicine employ incorrect methodologies. Many make very basic mistakes, such as not having separate training & test sets, using the test set (not a separate validation set) for feature selection, hyperparameter tuning, etc
There’s a reproducibility crisis brewing in almost every scientific field that has adopted machine learning. On July 28, we’re hosting an online workshop featuring a slate of expert speakers to help you diagnose and fix these problems in your own research: sites.google.com/princeton.edu/…
Important discussion about the reproducibility crisis of ML in science. Particularly when models are later used in medical products this has far reaching consequences. Great to see ideas on how to go about it. A data leakage taxonomy + model info sheets look like a good start.
Here’s the context. Dozens of scientific fields have adopted the prediction paradigm, and that’s great. But ML performance evaluation is notoriously tricky. At least 20 reviews in 17 fields have found widespread errors, and the list is quickly growing. reproducible.cs.princeton.edu/#rep-failures
What a nice system view of what containers are, with the complete write up at iximiuz.com/en/posts/conta…
How to grasp Containers and Docker (Mega Thread) When I started using containers back in 2015, I thought they were tiny virtual machines with a subsecond startup time. It was easy to follow tutorials from the Internet on how to put your Python or Node.js app into a container...
It is of course a product! Excellent insights on building platform engineering teams and products cncf.io/blog/2022/07/0… @matiasfrndz (via @P_Ensarguet thanks!)
A corollary to this is that one of the most valuable services a distributed system can provide to its customers is hiding grey failures (either by converting to fail-stop, or tolerating the underlying failures without exposing them to clients).
Crash fault tolerance gives a false sense of security. Just because your distributed system can handle crashes does not mean it can handle grey failures such as slow nodes, even if they feel “less serious” than nodes crashing.
On my lazy Sunday afternoon newspaper reading, someone recognises me, and asks "how should we think different about software development" I can talk hours about that, but I said "your software needs to be operated for decades longer that you write it, keep that in mind"
Can someone point me to a significant study about the impact of EV battery disposal 10-20 year from now? Thanks.

Lots of insights on IPv6 deployment
Moving to IPv6 was a wise decision for the computer networking ebook. This blog post provides lots of interesting data about the deployment of IPv6 during the last decade akamai.com/blog/trends/10…
