GIMP is very feature-rich already and to me seems to be in the stage where change is more incremental.
The single feature that prevents my wife from moving from Mac/Photoshop to Linux/GIMP is the lack of adjustment layers. This is the ability to non-destructively modify brightness/contrast/colour/etc. In GIMP, if you edit the contrast, then edit in another way, there is no way to re-manipulate the contrast again without losing information. As per the summary, Krita does have this capability. Apperently it's in development for GIMP.
I did hear about this, but I hadn't thought about writing a filter after receiving spam. That's a cool idea.
The only part that makes me slightly wary is that since so many use gmail, you'd think that spammers would automatically remove the +slashdot part pretty soon.
I don't even use spam blockers. Instead I've purchased a domain, which is quite affordable nowadays. I have a catch-all redirect, so I any mail addressed to *@mydomain.com.
Then, I give a unique username to each organisation. e.g. slashdot@mydomain.com. If I receive spam at this address, I inform them, then kill the username. I can also just create slashdot2@mydomain.com if I want to keep dealing with their company.
Now, I receive only a few spam emails each year, so I need to do zero automated filtering. I also don't have to deal with the worry of false positives at all.
Also, now I think about it a bit more, I think the phase difference between ears is also enough to make this unfeasible for higher frequencies. But yes, I agree that it should be possible (and useful) to cancel the low-frequency engine noise.
Okay, so we've a got a proposal. Where do we pitch it?
But the engine vibrations occur at a known spot at a fixed distance from every seat and are essentially constant for long periods.
That's a good point. I imagine that could work for gross cancellation of noise, especially at lower frequencies, but I still think there'd be too much variability at higher frequencies. For example, at 2 kHz, the wavelength is about 17 cm. Hence, if you are 9 cm away from the 'optimal' position, you'd be totally out of phase, and the noise would be worse. Obviously this precision is even more important for higher frequencies.
If you haven't seen it, it's a great satire on Hollywood. The opening scene in fantastic in its own right (8 minute, single take), and features writers pitching ideas to a producer, including the sequel to The Graduate. The conclusion is that Hollywood cannot find a new idea.
Quantity is no substitute for quality, but its the only one we've got.
