History in the making: Google Wave unveiled

Google Wave logoAs someone who spent a large chunk of  lifetime working on improving knowledge worker effectiveness, especially around computer mediated communication and  collaboration, I can barely contain my excitement.  I’ve just sat through the lengthy video of yesterday’s unveiling of Google Wave in the I/O developer conference. Not only have the good folks at Google integrated the most central processes of Computer Supported Collaborative Work – Email, IM, Shared document editing, Discussion boards, and more – into a single tool; but they’ve upgraded their underlying paradigms – which had changed very little in decades – into a dynamic, vibrant usage model that takes advantage of the latest Web 2.0 concepts (and then some).

.

The video is quite long, as was the demo, but well worth your time to watch. I won’t repeat the details; if you don’t have patience for the video, there are screenshots here and some info here. They include concepts we’ve been waiting to improve on for years (like properly dealing with, and visualizing,  discussion threads) and others I haven’t seen yet (like an intelligent, meaning-sensitive spell checker).

What will be very interesting to behold when this product comes out later this year is how different segments of the user base adapt to the new paradigm. The Social Networking set should be ecstatic, but what will large enterprises do? The new features of Wave could revolutionize their collaboration  effectiveness, so they stand to gain the most, but many large organizations are not known for their agility where new technology (or changes in ingrained cultural paradigms) are involved. Those who do adopt and unleash this power will have a serious competitive advantage, IMHO.

Kudos to the Google team that developed this down under!

Tweet tweet, I’m on Twitter! (Oh, frabjous day!)

Yes – after a long time saying I draw my line at “real” blogging, I’ve taken the plunge and set up on Twitter.

Twitter BirdAnd guess what? It looks like it’s gonna be a good move in many ways. The “what can you possibly say in 140 characters” objection I’ve already taken care of when I became active on Facebook; The tools available, for the PC and for my mobile device, look excellent; many of my friends are already up there; and the interlinking of tweets, blog posts, facebook updates and even full length articles on my web site looks natural and promising.

We’ll see where this goes; will post updates here when I have some more insight. Until then, you can follow me (I’m nzeldes, not surprisingly).

Disempowered Power Socket

Single and Double 220V mains sockets

Here are two mains power sockets from around our home. One is a standard grounded 220V socket. The second is obviously much better: in the same space, for the same trouble, it takes two plugs! In the USA this is of course standard practice; all wall socket panels have two sockets. Here, though, this is less common, perhaps because our plugs are larger. So – isn’t that twin socket neat?

Twin mains socket in useWell, it would have been, if the designer had been thinking. You can see the problem in the next photo: most grounded mains plugs have the cable coming out the side – and this means the second socket in this panel is obstructed by this cable. All it would take to fix this is to build the panel the other way around, with the ground connections on the outside rather than facing the center, or better yet, place the two plugs side by side with the cables going down towards the floor. Cost and complexity of production would have been identical; usefulness would have doubled.

Shame!

Vanquishing those pesky Torx screws

We live in an age of throw away technology, and for me, the silver lining of this has always been to take old products apart before trashing them. It’s fun, and it’s instructive to see how computers, home electronics, even the occasional appliance are built inside. And of course, you may bring to light gems like the 10-platter stack from inside a 1980’s PC hard drive, shown below.

Platters from a 1980's hard drive

The problem is, to get at this you need to open the drive up, and these are closed tight with scary “warranty void if removed” stickers (not a problem) and a dozen screws like the one above, right, that never have a normal Phillips head for which a normal person will have a normal screwdriver around! The use of more esoteric screws like this Torx screw makes dismantling delicate electronics a problem. What is needed, of course, is a specialty driver, but who has those?

Precision multi-driver setSo, I kept accumulating old hard drives from long gone computers… intending one day to take a power drill to their pesky screws, but never getting around to it… until one day I got fed up and solved the problem once and for all.

I went and bought a whole set of non-standard driver bits – not only Torx, but many other weird shapes, thirty bits in all. Not something I’d use daily, but it’s good to know I will never again be stumped by a stupid screw.

And of course, I took to my pile of old drives and had a field day taking them apart!

Tesseract – an action comic for the ultimate geek

Tesseract Comic panelNew on my Possibly Interesting site: a weird superhero comic spoof that I drew when I was studying Mathematics in College. It follows closely the style of 60’s Superman comics, but it takes place entirely in the domain of geometrical figures (and no, at that time I hadn’t yet read Abbott’s Flatland). Lost for years, it had surfaced in a drawer of old stuff, and I figured I might as well share it: if you, too, were a comics fan, and a geek to boot, you may enjoy this.

You can get the single episode ever drawn here, and you can read a bit of background here.

More waste of time

Last year I reported on the inefficient design of a teleconference system, as far as respect for the user’s time is concerned.

Today I sat through a really lovely case of this design issue. This system, speaking with a booming, ebullient voice, took me through the following:

System: Welcome to the conference center!

System: Please enter your passcode followed by the pound sign!

[I did]

System: Please hold while your passcode is being verified!

System (1 second later): Your passcode has been accepted!

System: You can press Star-Zero At any time during the conference to receive additional assistance!

System: At the tone please say your name then press the pound key!

[I did]

System: At the tone, you will be placed into the conference as the third participant!

Obviously, it would’ve been enough if after the second line – once I input the correct passcode – the system had connected me. All the rest of this monologue is useless (OK, in some situations, asking me to say my name may be useful too; but none of the rest).

And in fact, when I was placed into the conference, another participant who had just run this gauntlet of useless chatter said “I wanted to yell at the system “Just SHUT UP!”

Not that the system would have listened…  🙁

A feast of technical illustration

A picture is worth a thousand words – when it is a good picture. There is a huge gap in effectiveness between the best and the worst illustrations you see in technical and scientific publications. The trick is to convey the essence of what’s being shown, whether it is a machine, a building or an anatomical detail of some biological specimen, without drowning it in the irrelevant; and it gets trickier when you’re dealing with cutouts and other means of showing inner details of complex systems. Many illustrators never get the hang of it…

But today I accidentally surfed onto the site of Beau and Alan Daniels, producers of “cutaway, ghosted and phantom view illustrations in various styles including: Blueprint, watercolor, photorealistic, pencil, pen and ink, pastels, and black and white line art”… and they have an extensive portfolio there of incredible illustrations spanning technology, science and biology that is truly a feast to the eyes. I simply had to share it with you!

Take a look and enjoy!

Tiny phone, humongous software

I already praised my Nokia E71 smartphone, that marvel of miniaturized power. Well, today I tried to update Nokia PC Suite, the software that runs on my notebook to allow it to sync with the smartphone.

And as I was clicking through the installation process, something caught my eye in the dialog below:

Nokia PC Suite Installation Dialog

It was the number in parentheses: 290MB. That’s 290 million eights of binary digits.

And in case anyone thought this tool can calculate the answer to the question of Life, the Universe and Everything, or something equally formidable that might justify a size that not long ago would have sufficed for an entire operating system, the dialog explains: with this tool, you can connect your phone to a PC and access mobile content. I remember a tool I had long ago that did the same sort of thing; it was called LapLink and had fit on a floppy disk.

To be fair to Nokia, they aren’t the only ones pushing bloatware with their hardware; but the irony of a cool, tiny phone coming with a huge piece of support code is hard to ignore.

Car LED signs and the brotherhood of drivers

Driving on today’s highways can be an aggravating (and dangerous) experience, and it doesn’t help that you can only communicate with the other drivers around you by honking your horn – not exactly a medium conducive to feelings of brotherly love.

So one day, while wishing I could yell at the driver of the truck in front of me to please move a bit to the right so I might overtake it safely, it occurred to me that we badly need a means of car-to-car communication. One idea I had was to install a loudspeaker on every car like police cars have – so we could say “the yellow truck, please move to the right!”, or “Green Toyota, your back wheel is wobbling, better check it before it falls off!” or simply “Thanks!” when someone had slowed down to let us merge.

It then occurred to me that this could lead to a real cacophony on the road, so I had a better idea – why not simply add a LED marquee at the back of the car that would allow the driver to broadcast short messages to the car behind – say, “Sorry about that!” or “Keep a safe distance!” or even “You idiot, who taught you to drive?”…

Car LED Sign from Iwoot.comThis would be easy to do at the factory, but when I checked it out today I discovered that it exists as a retrofit: the charmingly named web company iwoot.com (the name stands for I Want One Of Those) sells a “LED Car Sign” that fits in the rear window and has an ingeniously simple controller allowing the driver to change the short messages displayed.

Great minds think alike… 🙂
