Comment Get a Mac - Use VoiceOver (Score 1) 47

OS X has a built in screen reader for those with visual impairments VoiceOver. The quality of this built-in software is better then expensive commercial software that needs to be added into Windows OS.

I iPhones have the the same VoiceOver visual impairment feature. Heard it works well but no personal experience here.

Comment Physical Backup? (Score 1) 239

You never said why you wanted to upload the photos but I'm assuming its for backup.

Why not go with physical backup. For 2 weeks at ~ 500 MB (2.5 MB/pic 200 pics) a day that a total of 7GB of photos. Easy to fit on a single memory card and just backup to your computer. If you are worried about loosing them memory cards are small enough to carry on person.

If it is to share your photos with people I would say stop and only upload your good shoots for the day.

Comment Cheating is Prevalent at Stanford (Score 1) 333

I can speak from my experience as a graduate student at Stanford who has TAed. Cheating among the undergrads is very prevalent and essentially impossible to prove. Stanford has a honor code and part of it is that during exams professors and TAs cannot be in the room to monitor the exam. The one person I know who has gotten caught cheating by resubmitting an exam for regrade and replacing several pages of the exam only got one quarter suspension (over the summer) and was still allowed to finish the class and receive a grade as if he never cheated.

Comment Wrong Use of the Word Efficiency (Score 1) 156

The catalyst is highly active but not to be confused with efficiency.

Ideally water oxidization would occur at 1.23 V vs RHE (higher is inefficient)
IrO2 operates at low potentials but is less active
(i.e. it requires more catalyst for the same amount of current)
This is not a bad thing more efficient but less active.

Comment Carbon Neutral* excluding waste streams (Score 3, Interesting) 206

I always love how processes that claim to be carbon neutral exclude the largest sources of waste such as reagents and solvents used in processing which are in excess to 1000x the product achieved.

And yes while some of these can be recovered somewhat on an industrial scale their recovery is highly energy intensive process.
