### Biotech Company Making Fossil Fuels With a 'Library' of Bacteria

Bacteria = 360 MWh, Solar = 2,569 MWh (386 comments)

If I did my math right, 10,000 gallons of gasoline is approximatley 360,000 kWh. Each acre is ~4046 square meters so the incident solar energy is approximately 2023 kW assuming approximately 500 W/m2. Assuming 12 hours of light a day results in 8,860,740 kWh of incident solar energy. Taking the 29% efficiency number from wikipedia yields a final total of 2,569,600. So a first order estimate says the bacteria will yield 360 MWh versus 2,569 MWh for solar. I'm sure there are other considerations I left out including how much it would cost both in energy and dollars to create a one acre field of each, but I was curious how the numbers compared as well.

### Will Patents Make NCAA Football Playoffs Impossible?

College Football != Entire Athletic Program (177 comments)

I believe the parent of this thread was specifically referring to college footbal, as this is the sport that has the highest paid coaches. The first reference you provide (don't have time to read the second one) is about athletic programs as a whole. You would likely find, that without football, athletic programs would lose substantially more.

Some quick googling found me the following article from 2006, http://money.cnn.com/2006/01/04/commentary/column_sportsbiz/sportsbiz/. One pertinent line is "USC's profit as a percentage of revenue is just 43 percent, below the average of 48 percent for all the reporting bowl teams [55], even when you include the 11 schools which lost money on their football programs. The top 20 football programs in terms of revenue have profit margins of about 60 percent, on average." And even these stats leave out secondary benefits, such as increased enrollment, donations, ...

### Video Appliance For a Large Library On a Network?

or Seagate... (516 comments)

I had tried over and over to build a computer that would work well for playing video and that would be easy to control, the video always seemed a little jerky, couldn't get the remote quite right, so I finally gave up a bought a Seagate FreeAgent Theater+ (www.Newegg.com P/N: N82E16822148499). It was on sale for \$70 when I bought it, then went on sale for \$50, now is out of stock. If it can be found anywhere, I would recommend it because it works great for me (sounds like I was looking to do the same thing). It can connect to my Windows shared drive and play the HD content perfectly. It can also access miscellaneous online sites like YouTube and NetFlix. I haven't had it long enough to see if there are easy ways to search and find media on the network shares, but I don't have a problem just browsing to the right folder and selecting the right file. I don't know how this device compares to the WD, but one thing I did notice about the WD is that the component video comes out of a little 1/4" jack + adapter, which I didn't think would be as robust as the RCA type plugs.

### HDBaseT Supporters Hope To Kiss HDMI Goodbye

Single Pair or 50 ns Diff (336 comments)

Two Thoughts: First. Could one send the entire digital audio/video signal over a single twisted pair. Second: 50 feet is approximately 50 ns. I would think 50 ns of difference would be imperceptible

### Berners-Lee Deconstructs a Bag of Chips

Northeast Brand (128 comments)

Yeah, I think Utz are limited to the North East of the United States. He probably should have said Lays if he at least wanted the whole United States to understand.

### MATLAB Can't Manipulate 64-Bit Integers

Re:MATLAB ~= fast (334 comments)

I believe MATLAB isn't strictly interpreted anymore, but instead does just-in-time compilation.

### MATLAB Can't Manipulate 64-Bit Integers

Re:MATLAB ~= fast (334 comments)

Depending on the Monte-Carlo simulation, I will have one iteration of the "for" loop execute many iterations of the Monte-Carlo. If I can't do this, than typically the overhead of the for loop isn't that significant.

### MATLAB Can't Manipulate 64-Bit Integers

Re:MATLAB ~= fast (334 comments)

There are many ways to avoid for loops in MATLAB. If there isn't a way to avoid the for loop it is usually because of the number of operations that are going on in the loop. If that many operations are going on in the for loop than the overhead of the for loop is diluted.

### MATLAB Can't Manipulate 64-Bit Integers

Re:MATLAB ~= fast (334 comments)

Don't know what your scientific language of choice is, but I have compared MATLAB programs to FORTRAN programs and the difference in speed was negligible. A properly written MATLAB function can be quite fast.

### MATLAB Can't Manipulate 64-Bit Integers

Memory moreso than computations (334 comments)

As another Engineer that uses MATLAB quite frequently, the only reason I have used 64-bit support was to analyze larger data sets.

### Palin Email Snoop Found Guilty On 2 Charges

ASCII or Hash (291 comments)

I believe a lot of those are insensitive to case, so does that mean that are stored as text and not as a hash (is hash the right word)? If so, would typing your password in those fields make your password more vulnerable?

### "Green" Ice Resurfacing Machines Fail In Vancouver

Re:Hockey games everyday? (356 comments)

In the mid-Atlantic, the places where the major hockey teams play also host concerts, basketball, etc... So I seriously doubt they play 365.

Actually, multiply by 2 again. I considered all games to be home games.

### "Green" Ice Resurfacing Machines Fail In Vancouver

Hockey games everyday? (356 comments)

I'm from the mid-Atlantic and the hockey teams I've heard about only play 82 games in a season, not the 365 that you considered. So does that push the recoupe time to 28.9 years. I'd be interested to see the life expectancy of the average Zamboni. Also, is the purchaser of the propane Zamboni storing the \$80K under their matress or investing in something a little more lucrative.

### How Can I Tell If My Computer Is Part of a Botnet?

Slip Streaming (491 comments)

Maybe you already know, but if you don't, you should look up "Slip Streaming". With "Slip Streaming" you copy your install CD to your harddrive, "Slip Stream" the Service Pack files in, then create an install CD that will at least install the most recent Service Packs. Saves from having to go through all the old Service Packs on reinstalls.
