Adobe still doesn’t understand this “world wide web” thang…

Given how badly Flash is getting smacked-down at the moment, I find this hilarious.

Right now, Adobe.com’s store page (where you get redirected if you google for Adobe products) doesn’t work in a mainstream desktop browser (Firefox). I go to the page, and suddenly my keyboard stops working, and the mouse is only half working. WTF?

Ah. A bit of digging, and I find crap like this:

…fully “custom” scrollbar, which I suspect is disabling keyboard and mouse input.

What does this achieve?

  1. HEY! It looks “different”!
  2. Confusing: looks like a Tab, instead of a scrollbar
  3. Reduces performance: this scrollbar *flickers* as you drag it, because the rendering routine is so horrendously slow. This is on a Core2 Duo processor that’s not doing anything else.

What does it break (aside from performance)?

  1. Keyboard navigation: spacebar, cursor keys, and left/right switch tab (VERY annoying: it seizes control of your keyboard and won’t let you navigate away)
  2. Mouse navigation: it bypasses the web-browser (stupid idea, Adobe), and so all the mouse gestures – even the OS-built-ins like 2-finger-scroll – stop working

It’s like a microcosm of why people get frustrated with Adobe – and perhaps of how Flash is going to go down in flames. It would be subtle and clever if today were April 1st:

  1. Who cares what the user thinks? Give them useless crap that doesn’t even look pretty! (think of the features added in most revisions of CS)
  2. …but FORCE it on them, too; choice is bad! (recall the Adobe trojan that they wrote to take over your PC and force-install Adobe products)
  3. Performance? Who cares about performance? (Illustrator and large files … nuff said)

How to cool down a Macbook Air … fast

Is your Macbook Air overheating? Here’s a technique I’ve been using for the last couple of years, works everytime. I suspect it still works on the new models – I *suspect* they have the same basic design flaws as the original, from looking at the case.

Problem: vents in wrong place

Those vents along the rear underside of the case … don’t work. I don’t know how they ended up there, but I suspect it was a triumph of “looks” over “not breaking the expensive laptop” (until Apple patched OS X, just running Flash was enough to cause OS shutdowns on a regular basis).

Solution: assume launch position…

Grab your Air, hold it at the hinge (so the lid doesn’t slam down and switch the laptop off), and tilt it towards you 90 degrees.

i.e. the keyboard half of the laptop should be vertical, resting on the long, bottom, edge.

The vents now vent air straight up – unimpeded – instead of down-and-out (impeded by the case itself).

Result: fast cooling

I can usually get an Air that’s been running “hot” (fans very loud and noisy) for minutes / hours to cool down in under 60 seconds using this technique.

Why does this matter?

Well … once an Air is cool, it tends to stay cool. i.e. it’s crap at bringing it’s own temperature down, but it’s got enough oomph to *keep* it at whatever temp is current. So, manual intervention fixes the problem.

Super-fast cooling (a.k.a. “PANIC!”)

What do you do if your Air starts beeping?

(hint: this is the never-actually-explained-to-you hardware warning that “your CPU is about to melt. Cool it down NOW or buy a new laptop”. I wonder how many people realise what’s happening when they hear that screeching, high-pitched beep and think “WTF?”)

As above, only shut the lid too.

This may seem counter-intuitive – after all, this will reduce the air-surface of the Air by about 50%, reducing it’s ability to cool down.

In practice, although that’s true at low temperature, at high temperature the heat is already concentrated in the top-left corner of the keyboard (where the CPU sits) – and most of the case is too far away to help.

In practice, closing the lid causes OS X to suspend processes, which normally takes enough load of the CPU that the laptop / hardware is able to cool itself MUCH faster – but only if you’re holding the whole laptop vertically, with the vents pointing upwards.

I’ve found this normally cools an Air from “max fans” to “silent” in under 15 seconds.
