From AI is wrestling with a replication crisis (HT: Drew Conry-Murray)

Last month Nature published a damning response written by 31 scientists to a study from Google Health that had appeared in the journal earlier this year. Google was describing successful trials of an AI that looked for signs of breast cancer in medical images. But according to its critics, the Google team provided so little information about its code and how it was tested that the study amounted to nothing more than a promotion of proprietary tech (emphasis mine).

Here’s another riff on the “when you’re the smartest person in the room, change the room” theme: The Trap of The Premature Senior by inimitable Charity Majors. Enjoy!

Did you ever experience an out-of-the-blue BGP session flap after you were running that peering for months? As Dmytro Shypovalov explains in his latest blog post, it’s always MTU (just kidding, of course it’s always DNS, but MTU blackholes nonetheless result in some crazy behavior).

A long while ago I wrote a blog post along the lines of “it’s ridiculous to allow developers to deploy directly to a public cloud while burdening them with all sorts of crazy barriers when deploying to an on-premises infrastructure,” effectively arguing for self-service approach to on-premises deployments.

Not surprisingly, the reality is grimmer than I expected (I’m appalled at how optimistic my predictions are even though I always come across as a die-hard grumpy pessimist), as explained in The Shared Irresponsibility Model in the Cloud by Dan Hubbard.

My friend Marjan Bradeško wrote a great article describing how we tend to forget common sense and rely too much on technology. I would strongly recommend you read it and start thinking about the choices you make when building a network with magic software-intent-defined-intelligent technology from your preferred vendor.

I was telling you there’s no need to become a programmer over six years ago, but of course nobody ever listens to grumpy old engineers… which didn’t stop Ethan Banks from writing another excellent advice on the same theme: Don’t Become A Developer, But Use Their Tools.

We all knew it for a long time, now it’s finally official: IP fragmentation is broken, or as the ever-so-diplomatic IETF likes to call it, IP Fragmentation is Considered Fragile.

Justin Pietsch is back with another must-read article, this time focused on high-speed Ethernet switching ASICs. I’ve rarely seen so many adjacent topics covered in a single easy-to-read article.

In one of his recent blog posts Tom Hollingsworth described what I semi-consciously felt about the CCIE lab exam for at least 25 years: it’s full of contrived scenarios that look more like Iron Chef than real life.

I understand they had to make the lab harder and harder to stop cheating (because talking with candidates and flunking the incompetents is obviously not an option), and there’s only so much one can do with a limited set of technologies… but forcing networking engineers to find ever-more-devious ways to solve overly-complex problems is nothing else but fuel for rampant MacGyverism.

One of the weekend reads collected by Russ White contained a pointer to a hilarious description of blockchain - a solution in search of a problem. Here are a few quotes to get you started (and I had a really hard time selecting just a few):

I’ve never seen so much bloated bombast fall so flat on closer inspection.

At its core, blockchain is a glorified spreadsheet.

The only thing is that there’s a huge gap between promise and reality. It seems that blockchain sounds best in a PowerPoint slide.
