A few days ago I saw this interesting setup on the wall in a medical center.
Obviously, this is the solution to the world’s energy needs. No more greenhouse emissions, no need for nuclear power plants, no oil shortages… just a clean, compact, self-contained electrical version of the classic Perpetuum Mobile.
The sign, in case you’re rusty on your Hebrew, says “Please don’t press the switch. “. An most reasonable request – interrupting the flow of free electricity would certainly not do…
There are many solutions that claim to repel flying insects; some even work.
For instance, there are chemicals – stuff you put on your skin, stuff you burn like incense – at least this makes sense: we can see how some smelly material may offend the insect’s finer sensibilities. Then there are hi-tech solutions, like the electronic gadgets that supposedly emit a hypersonic sound that mosquitoes can’t stand. We once tried this out – my son sneaked up on a mosquito standing on a wall and turned the gizmo on right next to the critter’s ear (or whatever they have). The insect didn’t even deign to move an antenna; maybe it was deaf (or maybe we were sold the electronic equivalent of snake oil).
But the most amazing device is one I snapped in a restaurant today: a nylon bag filled with water, hanging from the rafters (I’ve also seen them hanging from tree branches occasionally). And this traditional system is in use not only in Israel – as I discovered in Google, the same method is used in the US, Mexico and elsewhere: so it’s really globally known.
I asked the waiter why a water bag will drive flies away, and he said with great certainty that the fly sees its own enlarged reflection in the water and it scares it away. I heard this explanation before; presumably the fly thinks it just met a bigger, meaner fly, and decides that retreat would be prudent.
I have no idea whether anyone confirmed this theory (any input on this is welcome), but whether the explanation is correct or not, you have to admit this is one solution that is perfectly acceptable from all angles: environmentally friendly, harmless to humans, humane even to the flies, and as cheap as it gets.
Today, Nov. 13, is World Usability Day, sponsored by the Usability Professionals’ Association.
This has been running since 2005; each year, on the second Thursday of November, over 225 events are organized in over 40 countries around the world to raise awareness for the general public, and train professionals in the tools and issues central to good usability research, development and practice.
This year the theme is Transportation, with various practitioners and organizations addressing the impact of transport methods and practices on people and on the environment we live in. And while browsing some of this, I found this interesting research report from the UX Alliance on Parking Meters around the world, with a focus on their ease (or not) of operation. Turns out that “… no two parking meters … are completely the same and that the complexity of operating the parking meters varies considerably. There is a world of difference between the auto-detecting parking meter in Tokyo and the complex and error-prone parking ticket dispenser in Amsterdam.” The report, with numerous photos, is quite interesting and insightful about proper design (or otherwise) – recommended reading!
Ordered some books today and was surprised to find on the Amazon.com home page a message from Jeff Bezos telling of their new initiative to alleviate “Wrap Rage” – “Amazon Frustration-free packaging“. Apparently they plan to recruit leading manufacturers to put an end to clamshell blister packs, steel-wire ties and excessive cushioning materials.
They aren’t necessarily resorting to Julie Andrews’s “Brown paper packages tied up with strings”, but they will push for smaller, easy-to-open, recyclable cardboard boxes designed to minimize both waste and customer fury. What’s more, these plain boxes are designed to ship as they are, without need for an additional shipping carton. More details here.
What can I say? Good idea! I wish more vendors did that sort of thing.
Back from NYC… I already reported on the big stuff I saw there; and here is a small but annoying thing I also saw.
My hotel room had a drip coffee maker, a standard item in American hotel rooms (and much better than the old dependence on Room Service). But this one had one unusual feature. Instead of the usual plastic basket that you put a filter bag into, this one had no built in basket. The brew basket came in the filter pack – and was disposable.
You can see the content of the pack in the photo: the black plastic tray has a hole in the bottom, and you throw it out with the soggy filter bag after one use. The old system with a reusable basket was perfectly good – whatever gave anyone the idea that we need more trash on this planet?!…
And ironically, the packaging has the green “Rainforest Alliance” logo at the top which asserts it is environmentally friendly. Yah right!
