What about if someone set up a box to listen on port 9100, like it was a JetDirect-compatible printer, so you "print" documents to it; and convert the received documents to PDF and serve them out via an Apache server, so you can later download PDFs of what you "printed" from a web-based interface?
Then I would address them as "Mr. Goldberg".
Try this Windows ghostscript wrapper. It installs a printer, pops up a dialog box when you print to it which prompts for a filename, and then saves the PDF. There are many others like it, and all the DLLs and such you'd need to recreate it are out there for free too, but this is the only prepackaged one I've found which is free and isn't spyware/adware/etc.
This isn't a critique of VB per se, but more of the culture that surrounds it.
A quality program must be coded defensively, in other words it must assume that anything can fail at any time and that it must sensically deal with it. It must not make assumptions about external inputs. Unfortunately, few programs are coded to this level of quality, but they are the ones that you won't see security advisories about. Programs that are not coded defensively will, upon hitting a problem, exit with an error message that does not help you find out what that problem is, or continue doing something where it does not make sense to continue. Troubleshooting and maintaining defensively coded applications is simple - whereas with other applications a developer often just leaves the bug for eternity.
There is extremely little example code for VB that is coded defensively. If you disagree, please post a link to an example where code to open a file has a code path that is run specifically when the file can't be opened. In the meantime, google has 748000 hits for "80004005".
However, for your particular situation, this is largely moot. If you're already working with a specific developer, they will either code defensively or they won't, regardless of language.
And you think an OC-192 connectors on both sides of data transfers which requires direct connection using fiber-optic cables is an easy thing to set up between say Chile and US.
Compared to direct-connecting one arbitrary building in New York to another, absolutely.
If 1,000,000 customers want to watch 1,000,000 different things, or the people who want to watch the same thing are not along the same path, then it won't work.
That particular instance calls for servers near the client having copies of information (like akamai). But what do you suppose would be the most efficient way to make all those copies?
Does the ISP engage in the horrible nightmare of tracking every multicast stream to figure out how many times it branches
No, the transit ISP, through their peering agreements, would tilt the cost burden towards the client ISP and away from the server ISP. Some client ISPs would begin to meter their customers for it.
Another thing to consider is the technical cost of maintaining multicast state in all the necessary routers in the entire Internet.
The equivalent of 2.5 gallons of gas is 33 megajoules of energy. The southwestern US receives roughly 5 kilowatt hours per square meter of sun per day. 5 kWh is 18 megajoules. Ordinary solar cells are 12% efficient. If these cells are 33% efficient (similar to the very best and most expensive panels we put on satellites), you're going to need 5.5 square meters of cells to generate those 33 megajoules. Electrolysis isn't even close to 100% efficient, so more like 8 or 10 square meters. And those cells have to be kept at optimum tilt, not just plastered all over a car. And you get to double those area numbers if you live in a more temperate climate.
I would expect that people will be just as impressed by "pretty glowy metals"!
The half-life on anything that glows is a heck of a lot less than 10000 years. The Cesium-137 involved in that accident has a half-life of 30 years and would therefore give off just.0000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000006 % of the radiation it is giving off today in 10000 years.
based on the footprint, I would assume they have a 10kW inverter and 16-22 hours of battery run-time.
I don't see how you can squeeze 576 megajoules (16*3600*10000) into something the size of a filing cabinet using lead-acid batteries. According to Wikipedia, the batteries alone would weigh 5333kg.
One other critical thing is that for every joule you pump into a lead-acid battery, you can only get about 0.7 joules out. In addition, rectifiers/inverters for that power range are usually only about 90% efficient. If the difference between peak and non-peak power in your area is less than 50%, this device couldn't save you money if they gave it to you.
Speaking of Wikipedia, they have a good writeup on how to store energy. If it was as cheap or easy as they'd like you to believe, the power companies would do more of it for you and pocket the savings of not maintaining standby generators.
Seriously, is McAfee trying to imply that some executable code you download off the Internet from people/organizations of unknown repute is safe?
BTW, if 3% of people answered their questions correctly, that means that 5 of 8 questions effectively had 50% odds. For example, if 50% of people were able to get questions 5-8 correct, and everyone just flipped a coin to answer questions 1-4, you'd get a 3% all-correct rate.
Before Watt invented the steam engine, everyone thought that there was no way of designing an engine that could use linear momentum to generate angular momentum.
Except that Watt didn't merely author some web pages about his steam engine - he built one.
Entropy is simply technical constrait an engine or solonoid must overcome to become useful.
The way that you do that is through an outside energy source. Show us a car that regenerates all of its own fuel and we will happily rewrite the laws of thermodynamics for you.
Until then, every other serious modern engine design proposal (Kalina cycle, etc) comes with a thermodynamic cycle analysis. Where is his?
I came up with more engines http://www.newpath4.com/enginewow.htm which combines ice cold liquid air and hot steam together to clash and cross-combine inside the engine cylinder for both steam implosion & air explosion. Both forces slam toward the piston head at the Speed of Sound
I can personally recommend this guy's web pages to anyone who is a fan of Alex Chiu, Sollog, or the Timecube guy.
No hurry though - if he's gone fifty-four years without grasping the concepts of Entropy or Ideal Gas Laws, he'll probably go his whole life.
I can honestly tell you right now that if you had to buy an ounce of methanol, I couldn't tell you where to go to find it.
Hobby shops or chemical distributors.
Now, if they can make the fuel cell run on methanol, ethanol, or a mix of the two, then your options are wide open. Just buy a gallon of denatured alcohol at the hardware store and you're good for a week or two of untethered operation...
Hmmm, that wouldn't fly in court. The equal protection clause of the 14th amendment would require the law to be written so that the politicians have to allow everyone to smack them upside the head.
80% humidity? Sure. 105F? Sure. At the same time, in the Continental US? No. Such a combination isn't even on the heat index table.
Quote: "At very high temperatures, air is rarely if ever close to saturation because the saturation vapor pressure is very large. Thus there are blank entries in the Table for high temperature and high relative humidity combinations. In the United States, the highest dew point temperatures to persist for at least 12 hours are in the upper 70'soF, which, combined with a temperature of 90oF, corresponds with relative humidities about 70%. Only where both air and nearby water surfaces become very warm (such as in the Persian Gulf or the Red Sea, or immediately following a rain shower that saturates the soil on a hot summer day) are higher temperatures and relative humidities seen.
Relative Humidity is just that - relative to the temperature. 100% morning RH could mean 40% afternoon RH. Get the morning's wet bulb reading - it will tell you how humid the entire day will be.
With photovoltaic systems you have the nasty chemicals currently associated with manufacture
Sandia National Labs has an interesting non-photovoltaic solar power plant. Aimable mirrors focus light on a target, the target gets hot, molten salt transfers the heat to a heat exchanger which generates steam which drives a turbine. They can store enough heat in a vat of molten salt to continue producing power 24 hours a day, the efficiency exceeds that of the cheaper photovoltaics, and unlike wind, output power can be controlled to handle peak loads.
Funny how there's 215,000 hits on google for "cromulent" and 151,000 hits (70.2%) for "perfectly cromulent" - 192,000 (89.3%) if you leave off the quotes.
Can't someone say "pathetically cromulent", "tragically cromulent", "hopelessly cromulent", or "ambiguously cromulent" once in a while?
Calculations showed that the helicopter blades modestly increased the Specific Impulse (Isp) by about 20-30 seconds, which essentially carried the blades into orbit "for free". Thus, there was no overall gain from this method during ascent. However, the blades could be used to soft land the vehicle.
But for musicians, having a quiet machine that sits in a rack that isn't too deep means I can put a system in the same rack as the rest of my gear.
The only noisy parts of a machine are the moving parts - fans and disk drives.
The new fluid-bearing hard disks are very quiet (about 30dB) so fans will be your biggest concern.
With some mini-ITX C3-based systems, you don't need fans at all. A C3 may or may not be fast enough for what you're doing. If it is, then great. If not, then you'll want the fans you do need to be big, slow, muted, and low in number.
The difference between ATX and BTX is basically that the location of the CPU/memory/etc and the expansion slots are switched around. The theory is that this puts the processor directly behind the fan, which would then go in front.
With BTX's main fan at the front of the case, I wouldn't expect the sound from that fan to be very muted.
I'd also avoid 1U systems that require fans. 1U limits the fan diameter to about 1.5". You simply can't make a quiet 1.5" fan that moves enough air.
Explain to me how you can have an understanding of A records and IPv4, and a very basic understanding of what IPv6 is (not going into how it works or anything) and NOT know what an AAAA record is? I'm genuinely interested in the thought process.
Here: AAAA records are to IPv6 as A records are to IPv4.
And before someone says to just go read the RFCs, no, what needs to be made is a transition guide for those already familiar with IPv4.
Why would you purposely ignore information from its most likely source? If it helps to think about it this way, RFCs are like a blog from the 60's.
If I understood it, I'd probably take the extra time to make all my future software IPv6 compatible.
Most people who write socket code just cut and paste it from other applications anyway.
Successful techies have one thing in common: they are eager to learn. Be successful. Be eager to learn.
Why would I want to have the IPv6 routing table permanently shackled to the mess that is the IPv4 routing table?
Also, have you heard of: "::aaa.bbb.ccc.ddd"?
What previous version of IP are you talking about? You aren't seriously referring to Arpanet's NCP to IPv4 transition in 1981-1982 are you? Arpanet had roughly 200 hosts back then!
Last time I read a rant like that, it was from someone in upper management with a preconceived but dangerously incomplete notion of how something complex was supposed to work.
I'm very, very glad that IPv6 is an alternative to IPv4 and not an extension to it, and I'm also very glad that there is no "magic moment".

If you put in 62/125 micron fiber in 1985, you'd still be using it.
Assuming your business hasn't moved since 1985. Corning is discussing premise cabling here, and most leases require businesses to install their own cabling when they move in and demolish it when they move out. Unless you own the building, cabling is an expense, not an investment.
Are there any fiber cabling systems designed to work with cubicle furniture?
Does Corning have any shining examples of businesses that went with fiber instead of copper for premise wiring?
Copper isn't just for computers - how would you centrally power your phones so that they are available in a power outage?
I have heard (through a guy that could fix *anything*) that a higher-frequency AC system would save enormous amounts of energy. 50~60 Hz is far too low. Something more like 500~1000 Hz is more transmittable and more efficient to convert to DC later.
The tradeoffs, as I understand them, are that at higher frequencies, transformers can be made much smaller and more lightweight, however you also reduce the minimum size of things that can accidentally act as unwanted transformers (which can cause power to be transmitted wirelessly where it shouldn't, and also causes losses through eddy currents). At much higher frequencies (>100kHz), your transmission line requires careful design to avoid acting like an antenna or harmfully reflecting power back to its source. You also increase resistance due to the skin effect.
It'd be nice to be able to avoid 20-20000Hz for power distribution to avoid audible 'humming' interference in audio equipment, but 20kHz would probably be too high for power distribution except within a single building.
Existing transformers and A/C motors would need to be redesigned to run on a new frequency, regardless of what that frequency is.

I don't believe it's an all or nothing thing.
No, however, convincing a major backbone company to learn about multicast and implement it definately is that cheap.
