Maybe you're thinking of dynamic linking against zlib or other compression libraries. This would use the same code, quite literally. That would be the most usefull way to support a card like this. The zlib.so (or zlib.dll) could be modified to interface the drivers for the card, so programs linked against zlib would transparently use the faster hardware acceleration. Few programs will be statically linked to zlib anyway, and those exceptions are likely to either be binaries you don't mind recompiling for speed (e.g. you linked it statically and tweaked the binary for speed already) or binaries on some rescue disk or small root filesystem where zlib.so may not be readable.
Because http browsers don't decode bzip2 on the fly, but can decode gzip on the fly. This is aimed at servers compressing their output on the fly. Offloading this task from the CPU frees more room for dynamic page processing or SSL calculations.
These will initially be targeted at higher margin items. A poster suggested a clothes washer that could send you an email when it is finished washing a load. This wouldn't appear in a Roper (about a 4% margin), but more likely a Kennmore Elite or Maytag Neptune. A refrigertator with online access to temperature and enegry usage graphs is more likely to be a $3999 SubZero than a $399 GE. The good thing about this product is that as more people use it, pricing will drop and it will work its way down to mid-range products where the margins are thinner.
Be careful not to lump start-up and small businesses together. Small businesses are more or less the best of both worlds. The president or owner is likely to know you on a first-name basis. You will gain great networking from this. Most small businesses care more about their people. Though not immune to layoffs, small businesses are more personal, likely to ride out tough times with you. At a small business you are more likely to understand the workings of the company, especially the revenue streams, on a day to day basis. You'll see the downturn coming. Unlike a small business, there are not likely to be 7AM to 7PM work days and fiece competition to get those extra stock options. Yet because your boss knows you, you are unlikely to slack off or slip through the cracks like many in corporate environments can. If the business size is more than 5, you will probably get the same or better benefits than most corporations can offer, excluding some things like on-site gym. There are disadvantages though, especially in IT. The ceiling for promotions is lower at a small business unless it is an IT-centered business. Still, how many large companies are going to have Beer Fridays during normal working hours?
A tangent to that is what kinds of policies do you have to create to minimized damages from this type of problem? If you fire someone who created a backdoor, what other back doors and vulnerabilities will you learn about when the disgruntled worked leaves? How do you make sure clients/end users are quickly informed of the issue and updates are quickly available? These points are especially important to consider when dealing with large software products that have an internet presence.
I'd like to think that outlawing spam will clean it up quickly. Unfortunately, I get tons of junk faxes at work, including some from Fax.com who has lost a HUGE lawsuit (no one has collected as far as I know).

Do we think spamers are going to be easier to track down and contain? Filters, while often one step behind spammers, limit the audience of spam greatly. When spam reaches the point that the return on investment is small or negative, then it will slow down.
If we go after the people receiving benefit from the spam and use good filters, then we are more likely to slow spam down.
If it is impossible to effectively block the spam, why does Mr. Shein believe it would be reasonably easy to collect on spam? Spammers are just not the type to be honest. Does he think they are going to start using real "From:" addresses and stop using open relays and throw-away accounts?
The strange part of the article is this:
Key to the success of the plan would be the participation of the major consumer Internet service providers... If those companies banded together and threatened to cut bulk-mailers off from their recipients -- combining that threat with the incentive of easier access to the recipients if the bulk mailers pay a reasonable fee -- bulk mailers would have no choice but to go along with it.
Get real. These ISPs have been cutting bulk-mailers off from their recipients the best they can already. So by the whole premise of spam being impossible to filter, Mr. Shein contradicts the feasability of the idea. We could go after spammers who do not pay if such a plan were enacted. But really, we can go after spammers now in many states and we all know how well that works. Good luck trying to collect Mr. Shein. If I get spam from your ISP because you are tryin a "make it legit" experiment, I will be sure to forward it back to you.

Butane does not create a very good pressure wave when combusted, especially not compared to the black powder used in most rocket engines. It is liquid in the lighters, but must be oxygenated to combust well. That is why butane is used to make flames in lighters and torches, not explosives. As a kid we used to blow up lighters by throwing them in fires (don't try this at home hehe). They typically make a large flame (1m long) or fireball (~1/4m diameter) for less than 1/10 second and fly a few meters in the air. A truckload of lighters would make a bigger fireball, possible break some windows and produce a neat rumble, but wouldn't take down buildings or spread some WMD very far. And it would take a lot of work to make sure all that butane had plenty of oxygen to burn quickly. Otherwise it would just burn like a large gas fireplace.
As others suggested, the government really had little to do with it. As far as I know, these were almost all privately owned or owned by small local governments. Lawyers had more to do with it, directly or indirectly. Several things can lead to this destruction. One, the insurer of the property says "Oh, you have a runway on the property? You need to erect a 12" double fence with razor wire along the entire perimeter. Even after that your premiums will go up 400 percent." Someone could land a plane (even without permission) and hit a pothole, crash, then sue you. Think diving boards and pools. The other likelyhood is that some people go out drinking, then decide to race on the strip. Only there is a pothole or maybe the guy just can't even drive straight. Boom! He hits a tree, dranage ditch, or whatever and his heirs, with the help of a lawyer found on the back of the Yellow Pages, are now suing for funeral costs plus a few million so they can move out of the double-wide.
Someone said "there aren't trees near runways." Well in Tennessee, trees grow everywhere. Every small airstrip I've seen in this area is surrounded by trees. They may night be right next to the runway and certainly not near the ends, but if you're driving your 350cid El Camino at 100mph and blow a tire, those trees are certainly within killing range.
The one group that does know of the existance of all of these small little airfields is the DEA. With a small prop engine plane able to land nearly anywhere that's fairly long and flat it makes it virtually impossible to make any attempt to stop these planes from landing and dropping their loot.
I certainly expected the DEA to know about these, especially near borders and the southern coastlines. Some of the airfields in my area (Tennessee) that were abandoned were cut up with deep trenches every 50 yards or so, with the dirt piled onto the runways. This far north the effect was not to prevent smuggling as much as to prevent drag racing.
Most commercially-available solar panels of the silicon variety are derived from purified sand. Pure silicon does not exist naturally, so silicon dioxide (duh, sand) is broken down and refined into ingots. How is this environmentally unfriendly?
Well, this process requires large amounts of electrcity to heat the silicon dioxide. It doesn't just become pure silicon if you ask it to. Silicon has a melting point of 1410C, and to get really pure silicon, you must melt it several times, recrystalizing it each time. There was a period where the estimated lifetime of solar cells was short enough and their efficiency low enough that the cell would not be able to generate enough electricity under even the most ideal conditions to make up for the amount of energy used to create the cell. That is no longer the case.
However, I imaging the poster was confused by the large amount of chemicals required to create semiconductors, especially multilayered microprocessors. Those require extremly pure silicon (99.999% or better), plus an etching process involving hydroflouric acid and many liters of water. Luckily manufacturers have refined ways of recycling these chemicals and the water.

It's true that the sellers want that. However, you may have noticed spammers are not always the sellers. The seller is looking for someone to do some "email marketing" for them. They are looking for wide coverage. They want to see things like "your email can be sent to 30 million unique email addresses," which means a few million that might get through, a few thousand that will actually get read, and maybe a few purchases. Spammers are just creepy marketers who want to make it sound like emailing as many people as possible is better, and should cost the seller more. Since they use open relays and random forged "From" email addresses, they never see what email gets blocked. Using images in HTML email they can get an idea of how many emails were read (this is why you should turn off images in email). While the spammer makes a commission on every sold item, they also make money selling lists and marketing services.
The numbers are part of their pissing contest, and the pool is your inbox. Spammers are not that bright, but their customers are much, much more stupid.

Graffiti wasn't released as a replacement for handwriting recognition, which was pretty bad on all devices in the mid 90's. Graffiti's idea was to limit the acceptable characters so they must be drawn in a certain way - not really as letters in all cases - to minimize the computations required to figure out what letter the user just "wrote". The handwriting recognition on Newton was limited in quality by the CPU power you could get in a mobile device and keep it affordable (and not be a power hog). Graffiti was another approach to the problem of user input, as an alternative to HWR, not an enhancement. Early reviews were skeptical that it would be successfull since you had to learn a new way to write.
Now that CPU power has vastly increased in mobile devices, full fledged handwriting recognition is much more feasible.
