I was in a meeting once where someone pitched a really unrealistic idea. I don’t remember the details exactly. But let’s assume this idea depended on pigs being able to fly.

“But how will the pigs fly?”, we asked.

“Oh, we’ll have an algorithm.”

“OK… But, we don’t understand how the algorithm make the pigs fly?”

“I just said, the algorithm will sort that out.”

“But you haven’t explained how?”

“With the algorithm.”

“Algorithms can’t make pigs fly.”

“Algorithm!”

Don’t devolve your thinking to an algorithm.

What happens when you let computers optimise floorplans

Evolving floorplans

The rooms and expected flow of people are given to a genetic algorithm which attempts to optimize the layout to minimize walking time, the use of hallways, etc. The creative goal is to approach floor plan design solely from the perspective of optimization and without regard for convention, constructability, etc.

I’m not sure this would work in real life. But it’s a fascinating idea, and the floorplans are certainly interesting to look at.

We are all trapped in the “Feed”

We are all trapped in the “Feed”

Om Malik summarises the problem with the big social media companies whose algorithms are causing us to drown in junk content.

Many have forgotten, but services like Digg helped popularize the idea of what I call intellectual spam. Headlines, followed by vapid content, meant to attract the likes. Against such a backdrop, a decade ago, we all assumed that the rise of the personal web, shaped by individual data would result in signals that will help us dampen the noise. We thought that our systems would get smarter, learning from our behavior, and we would be able to separate signal from noise. And this would allow us to focus our attention on the meaningful and essential.

Unfortunately, the reality of capitalism and turned that dream into a big giant popularity contest, shaped by crude tools – likes, hearts, retweets, and re-shares. We have created systems that boost noise and weaken signals. Every time I tune into news and all I see is noise rising to the top. Whether it is YouTube or Instagram — all you see are memes that are candy-colored candy, mean to keep us hooked.

The Facebook algorithm mom problem

The Facebook algorithm mom problem

An excellent description of one of the reasons I developed a distaste for Facebook for.

I write my content on my own personal site. I automatically syndicate it to Facebook. My mom, who seems to be on Facebook 24/7, immediately clicks “like” on the post. The Facebook algorithm immediately thinks that because my mom liked it, it must be a family related piece of content…

The algorithm narrows the presentation of the content down to very close family. Then my mom’s sister sees it and clicks “like” moments later. Now Facebook’s algorithm has created a self-fulfilling prophesy and further narrows the audience of my post. As a result, my post gets no further exposure on Facebook…
