Comment: Google did leave my poor Nexus S hobbled (Score 1) 275

I have to say that Google certainly left my Nexus S in bad shape, they updated it all the way to 4.1.2 which was too resource heavy for it, then didn't update it to 4.2 which contained a bunch of performance improvements that the NS badly needed! I've been on a close to stock custom rom since then, and every major release has improved it until it's now very usable on KitKat.

Obviously in the mean time I upgraded, but it still makes a very usable 2nd phone running KK.

I like to think that my contact lenses give me cyborg eyes (eg. technology that is so integrated with a person that it becomes an extension of their own body, while offering enhanced capabilities) - not only do they give me perfect vision but they're also UV protective :)

Plus I use dailies so I don't have to worry about cleaning or losing them.

Can't be doing with contact lenses though. Went for a trial, couldn't even keep my eye open for them to put the test lens in, so that was the end of that. Ugh, actually putting something on to the surface of one's eye? *shudder*

There's a trick I use where instead of going straight for the pupil (damn brain's all like "nope!" and shuts my eyelid), I place it to one side then shift it round a bit. A few blinks later and it's centred itself. Again to take it off I shift it round first before grabbing at it so my eye doesn't see my finger while I'm doing it.

Here are tons of smart people, I don't see anybody talking about training eyes - recovering without surgery. but I know that I it is possible to get very good results without altering your body irreversible.

Maybe because all the medical studies done on vision training for myopia have failed to find any evidence that it has any physical effect?

Are you confusing it with vision therapy for eye movement and co-ordination disorders?

Becquerels are tiny units. In the first 3 months after the accident 14 Quadrillion (1.5x10^16) becquerels were released. For comparison Chernobyl released 14 Quintillion (1.4x10^19) becquerels in total. (source).

Compared to that, 1 trillion (1.1x10^12) becquerels is a big improvement in rate of release and according to Wolfram Alpha represents around 300mg of Cs-137.

I'm not convinced webP is better, I've done a quick comparison and to my eyes JPEG beats it on like for like file sizes:

40k jpeg vs 40k webP (images converted to png for your viewing convenience)

Compared to the lossless original (one of Google's own webP comparison images) the webP version has lost more chroma resolution, leading to desaturation in parts and blurring of strong colour details like the red arm band.

It would be nice as a replacement for PNGs with alpha channels though.

It's more like the Sikorsky X2. The dual rotors are an important feature; With a single rotor as you increase forward speed you lose lift on one side of the rotor as it slower relative airspeed, until it's basically going backwards. Having contra-rotating rotors means that one side will always have blades going "forwards" regardless of airspeed.

Is it really a single board computer, if the SoC is on a separate board?

Looks more like a mini, more powerful version of the Raspberry Pi Compute Module with a Raspberry Pi like breakout board.

Those SoC modules themselves could be useful on their own if they sell the sockets to use on custom circuit boards...

If at first you don't succeed, you must be a programmer.

Working...
