Mac mini G4 vs Raspi 3

The Original Mac Mini G4 had a single-core 32-Bit PowerPC CPU at some 1.25 GHz with 512 KB on-chip Cache. It was released in 2005.

It has a Geekbench Score of 766.

 

Raspi 3 by User:Evan-Amos

The Raspberry Pi basically is a a cellphone, without the battery and the packaging. The Raspberry Pi 3 was released in 2016, and has a BCM 2837 with a quadcore ARM with 1.2 GHz.

It has a Geekbench Score of 2128.

In case you need to illustrate how Moore’s Law works, in a practical, touchable way.

When the ice melts, what does that look like?

Drum-Heller-Channels by User:Woofles

National Geographic’s Glenn Hodges explains the Channeled Scablands of Washington State, with some quite awesome photos by Michael Melford.

In the middle of eastern Washington, in a desert that gets less than eight inches of rain a year, stands what was once the largest waterfall in the world. It is three miles wide and 400 feet high—ten times the size of Niagara Falls—with plunge pools at its base suggesting the erosive power of an immense flow of water.

Before Code, there was the Codex

Nautilus has an article by Philip Auerswald, Author of The Code Economy: A Forty-Thousand-Year History. Auerswald tries to tie our current practice of crystallising rules in Code back to the Codexes and Recipes of older times, and sees our civilisation as a system of dealing with complexity by packaging and encapsulating it. According to Auerswald, running Code on machines is new, previously we have been running it on humans:

“Code” as I intend it incorporates elements of computer code, genetic code, cryptologic code, and other forms as well. But, as I describe in my book The Code Economy: A Forty-Thousand Year History, published this year, it also stands as its own concept—the algorithms that guide production in the economy—for which no adequate word yet exists. Code can include instructions we follow consciously and purposively, and those we follow unconsciously and intuitively.

When you commit to git, how long does it matter?

Commit to git

Erik Bernhardsson has been running Big Data on Git repositories of various kinds.

He was trying to find out what the half-life of code is. That is, when you commit to a repository, your code becomes part of a project, but eventually other code will replace it and it will no longer be part of the current version. How stable is the codebase, what is the half-life of code? And why is it different in different projects?

As a project evolves, does the new code just add on top of the old code? Or does it replace the old code slowly over time? In order to understand this, I built a little thing to analyze Git projects, with help from the formidable GitPython project. The idea is to go back in history historical and run a git blame […]

Magic circles banning autonomous cars

Trapping Autonomous Cars

Somebody sent me a link to Vice withe the comment “A multiple hit in the Venn Diagram of your interests”.

It’s about an artist using technology disguised as ritual magic to trap self-driving cars (and similar shenanigans). The assessent was correct, this is beautiful.

The image from the article shown above shows a self-driving car inside fake street markings. The broken lines allow the cars logic to enter the circle, the unbroken linkes mark a demarcation that must not be crossed, hence the car can never leave.

It ties back to a story my driving instructor told me. He was making a point about “How things are being presented matters”, relating about a beginners driver who had been told to imagine unbroken lines as a “wall that cannot be crossed” and who because of that had problems – sometimes rules must be broken to preserve their meaning and spirit.

Netways OSDC 2017: Something Openshift Kubernetes Containers

OSDC 2017 Registration
I will be speaking at the Netways Open Source Data Center Conference, which is in Berlin between May 16 and 18.

At work, we are currently busy loading our first two Kubernetes Clusters (Openshift actually) with workloads.

What exactly will be in the slides I do not know, yet, but it will be about our journey at Booking, the transition from automated baremetal provisioning of rather monolithic applications to a more containerized setup and the changes and challenges this brings. It will be very much a snapshot of the state of things at that point in time, and our learnings and perspective then.
