You don't say what your budget is, but good, sturdy workbenches (like these) with plenty of outlets for power supplies, scopes, meters, etc. as well as built in drawers and cabinet space.
If you are looking for suggestions on equipment, power supplies like the Topward 6000D series or similar (multiple output, adjustable, current limiting supplies) are invaluable. Good o-scope, handheld multimeter, etc. if you don't already have that stuff.
No, there is a big difference between Near-infrared (0.75 - 1.4 um) -- which is what CCD is sensitive to without a filter -- and Far-infrared (8 - 15 um) -- which is the thermal imaging range.
There was new firmware recently released (Amazon release notes) that adds, among other things like longer battery life, native PDF reader support to the Kindle 2. (Note, the Kindle DX had native PDF support since it was released months ago.)
I thought of the same thing. Thankfully the users guide shows the menu option for setting the orientation. (It's in the same menu as setting the text size).
I'll second the Logitech V470. It's smooth and accurate and has great battery life. It does have a small lag if you have not moved it for a while, but a small movement is enough to get going again.
I'll add another plug for the NSLU. Got one of those handling image data from remote security cameras. Works great. Note that you have to have USB hard drive however, as it does not have SATA support directly.
Also, I did mod the box so that it powers back on automatically after a power failure.
The Seamonkey suite is the ongoing project of the original Mozilla Suite. It has the functionality of Netscape 7 (plus some) as well as the updated support of the rendering engine from Firefox 2 and other security updates. (see the news release for more info.
Disclosure: I have been running Mozilla suite and now Seamonkey since about 1999.
One problem with this plan that I see:
What happens to the music that I have listened to when I stop paying the monthly fee?
If I can still play all the songs that I have downloaded, then why not just pay a couple of months each year and download as much as my bandwidth will allow.
If I cannot play the songs after the fee is no longer paid, I would probably not use such a system.
Otherwise, I do like the idea of benefit tied to actual usage, not just downloads.
I used to use York Photo to process my film several years ago. Good price, good processing, good reliability. I have not used their digital services though.
The NET Bible project has reached first edition completion that is free to download/distribute (and you can purchase a dead tree edition for reasonable cost).
A very good tool with plenty of translaters notes, etc.
From your link: The performance of a 0.25×3 m2 pseudomorphic heteojunction bipolar transistors achieves peak fT of 710 GHz (fMAX=340 GHz)... (emphasis mine)
So, maximum achievable frequency is actually quite a bit lower than 710GHz.
Also, the article acknowledges that faster transistors exist ("Alternative approaches for building fast transistors exist but they use other materials, such as gallium arsenide or a silicon germanium mix, which require more expensive manufacturing techniques."), but this is a method that can be adapted to existing silicon manufacturing processes.
The article also qualified the claim ("...set a new world record for the fastest transistor of its type."), but of course this is not as sensational of a headline, so did not make it into the summary.
Actually, the article says that they created a BJT transistor "The research was carried out using a simple type of transistor known as a silicon bipolar transistor."
Processors use FET transistors because BJT transistors need current to bias them all the time. These transistors would consume way too much power to make any sort of processor (especially for mobile devices). As others have commented, this would only be useful for the analog processing of the output transmitter.
For embedded systems, the really big draw here is the speed. EEPROM is great, but you have to have long delays after writing (~10ms usually) where the data sheet from freescale shows the entire write cycle at less than 35ns! That, plus true random access writes (unlike the Flash page read/modify/write method) is great news for embedded systems developers.
I remember fondly the small mods that were interesting diversions. Anyone else remember "Rocket-Crowbar" mod where all the weapons changed, but the levels were the same. The jetpack definately made for some interesting firefights...
Here at Levenger is a nice solution. It does not have any shelves or drawers, but it is designed to hold a laptop (or books/papers, etc) for working on a couch or chair. Very nice quality stuff at Levenger.
Not just interferance, but bandwidth. Just because your controlling frequency generator does not fluctuate much does not mean that the signal bandwidth does not apply.
Actually, the technology in question is a variation on the standard MIDI made by Yamaha for their pianos (and high-end keyboards). The difference is that normally MIDI can only tell the note, duration, and voice. This format, however, can also tell key velocity.
I have one of Yamaha's Clavinova electric pianos, and I can tell you that the MIDI recordings done on the keyboard, and played back on it are far above when played on regular computer MIDI tool. Being able to have volume control adds much to a MIDI file.
One issue that I have known people to have a problem with is that without (good) credit, it can be difficult to get decent credit card. (i.e. one with no fees) Some cards will charge fees even if you pay off the balance every month.
I have read a paper about this before. It seems that the flourescent flicker can be noticed by some people and they have to reduce the backlight brightness to avoid headaches, etc.
That is what I was thinking. The extra terms are common permutations of the topic of the page that could be searched for. Trying to make sure that a relavent return makes it into the search results is different than putting many unrelated words in an attempt to garner page hits.

Don't know if that would be a good idea. Could end up like a guy in a Nova braking suddenly to keep a cement truck from tailgating.
