back to article Squeeze the banana to log into this office Wi-Fi

In some offices, you have to ask around for the Wi-Fi password, or find it written down on a bit of paper. In others, you do it by poking a banana. Danish network engineer Stefan Milo constructed his fruity authentication system by wiring a piece of fruit to a Makey Makey board and a Raspberry Pi mounted on acrylic glass. The …

All bananas in any kind of office go mouldy and funny after a couple of days. It's good to get some use out of them.

"Surely the banana will go all mouldy and funny after a couple of days, though?"

Yes. But it is classed as a consumable.

"But it's a nice idea."

And high in potassium.

Corporate fruit bowl bananas are so underripe, a chance for the starches to break down into sugars is not a big obstacle - it then becomes more pleasant to eat, and you can replace it with another inedible one.

"...small piece of paper that someone printed out on an A4... ...I cringe"

It perfectly obvious that the total environmental footprint of the banana-based system is at least a couple of orders of magnitude higher than the paper-based system. Just the banana-to-paper ratio makes it obvious. Let alone the continuous power consumption, even sans-banana.

Planet killer.

The bananas given in our staffroom are green and crunchy. They have a really fine balance as you need to keep on in your pigeon hole for precisely 2.25 days. If you wait longer they instantly turn black and mushy.

The real problem, as I see it, is the well-known banana genetic bottleneck.

Banana plants are asexual rhizomatic herbs; the banana fruit is a vestigial berry. So you basically have a closed-source system here with a single point of failure from an unreliable supplier.

Should've gone with a tomato, if you had to have a berry. (Handy rule of thumb: Sexually-functional berries are more reliable.) Or skipped the berries entirely and used a strawberry, which of course is a fleshy stem.

I think...

The idea is bananas.

In a few weeks the security on that might be a bit stale.

With all the multiple users it has a high risk of catching some bugs.

They may have taken "code monkeys" too literally.

I'm sorry, but why pick a banana, surely their MTBF is the lowest of just about any fruit.

Yes, but the banana provides a simple visual check of how close to failure it is. Change when >25% covered in brown spots.

For a real problem fruit for this rig you can't beat a pear. Those little fuckers go from inedibly hard to overripe while your back's turned. A bowl of pears is a waste of space, unless you can scoff the lot in the brief few seconds while they're perfectly ripe.

Props for the clever solution to a problem but, one is forced to wonder if the device is indeed cellular, modular, AND interactivodular.

could be worse

It could request that you pull on a sausage or squish some plums. I also have to wonder if the cost of fruit / extra electricity (whilst I admit it will be small but it's an extra machine that wouldn't have otherwise been running. Unless you turn off the Secretaries machine in which case all the better) would offset the cost of the paper?

Could be far worse, like the South Park vehicle (IT) invented by Mr. Garrison:

acrylic glass - WTF?

Is it a piece of hardened silica and chems or a piece of reconstructed petro chemistry?

Re: acrylic glass - WTF?

It meets both the dictionary definition of a transparent hard substance used to make windows, and the chemistry definition of a substance that hardens without crystallisation. So yes, acrylic glass.

Just to be a pedant, acrylic forms a regular repeating polymer, therefore it is not a glass.

Re: acrylic glass - WTF?

To be an even bigger pedant, a glass is a solid with no regular long-range structure. Most materials can exist in the form of a glass - even if their usual form is crystalline. For example, both water and some metal alloys will form a glass in the right conditions.

Furthermore, crystallinity is not a yes or no proposition: it is quite possible (and in the case of polymers, even common) to form a structure where microscopic parts of the material form a regular, crystalline structure, while other, connected regions are amorphous.

A regular repeating structure of the polymer chain is necessary, but does not guarantee that it will form a crystalline material (ie a material with regular long-range structure). Depending on the technique used for polymerization and the subsequent handling, the resulting polymer may have crystallinity anywhere in the 0 to 100% range.
