Re:How much do these things cost?
Blue lasers used in Ps3 are 405nm but they don't cost so much as the one above. According to financial times, the price dropped to Y3,000 (25USD) http://www.ft.com/cms/s/b0638092-8fc1-11db-9ba3-0
0 00779e2340.html They used to cost from $120 to $180 according to this ieee report http://www.spectrum.ieee.org/mar07/4988/2 "the GaN lasers in these units now account for 20 to 30 percent of the product's retail price of about $600" So there you go, a price fall of $90 to $150 in the cost of the blue laser diode. -
Re:Professional
There are codes of ethics and conduct in the profession. IEEE's code and ACM's code are out there. They do not specifically address software piracy but both condemn harming property. In this forum, it is often mentioned that this activity is not exactly theft but illicit copying. Nonetheless, I would throw software piracy into the realm of property harm in the context of the code of ethics.
It sounds like this activity is already rampant. It is less clear if it can be pinned on you or not. Are those involved aware the licensing agreements are being violated? Are they aware of the fines for such things? Are they aware of the implications of getting caught (an IT professional could end a career, a business could go under)?
There are people who do not care. Some people would consider this the same situation as exceeding the speed limit by 5 miles per hour. Some feel that the prices are unreasonably high for the product and choose this as a mild practice of civil disobedience.
I do not want to sugar coat your situation, though. The IEEE regularly reports that a whistleblower is screwed. Despite all the laws and rules put into place to protect such a person, the career could end. The company may stop providing advancement and raises. The company may provide very negative references. The company may even engage in unlawful termination activity. All of this, however, is difficult to prove in court. The result would be large legal bills and no income. Read more about it:

Your most pragmatic approach may be to get a new job and report them to something like BSA later. That may sound like a case of sour grapes, but there are no perfect solutions.
Good luck with your choice: it is a matter of selecting imperfect solutions in an imperfect world.
PS: Your work computer belongs to the company. They may already be monitoring you. As a member of IT, you may be more aware of the monitoring than others. Keep it in mind, however, because secrecy and anonymity tend to be important in these matters. -
Re:or evertything else...
Here's one article: http://www.spectrum.ieee.org/print/4891
The Breeder reactor article on Wiki is also informative. -
Re:well... truthfully...
it always seems to me that their conclusions are specious. I can't think of any specific episodes right now but they over simplify the data, build elaborate setups that are prone to error, and use inadequate controls.
Or, more likely, test a subset and claim it applies to the entire set.
E.g., the Cell phones on a plane episode, where they claim a cellphone will not interfere with the avionics of a jet. Unfortunately, this is true for the cellphones they tested, plus the jet they tested. It unfortunately doesn't apply to the general case (sure, they did find 800MHz phones interfered, but modern phones don't...). The IEEE did a more elaborate series of experiments and found some very surprising results, including loss of GPS satellite lock, to instrumentation drift. Or heck, I've even heard interference of the cellphones while flying (the characteristic buzzing was easily heard over the radio). -
Re:FCC?
Shouldn't that be FAA?
And when are these asshats going to learn that cell phones do not interfere with flight controls? You'd figure at least one of them had to watch that MythBusters episode.
Uh, the IEEE have conducted a few more detailed experiments than the Mythbusters (nothing against them - I like the show), and have found that certain cellphones cause issues with avionics.
Not all cellphones, not all planes, not all avionics - its combinations of them. The interesting one is causing GPS to lose satellite lock, which can be serious if using GPS approaches, since the plane must abort and divert (won't happen at big airports with traditional ILS, but smaller ones who find that a GPS approach is far cheaper than the expensive ILS equipment).
And it's not just cellphones, but certain consumer electronics have had documented effects. Whether anything has actually caused a crash is yet to be determined since most accidents are a chain of events, rather than a single smoking gun. (BTW, unrelated fact - yes, most accidents actually happen near airports than enroute cruise. Just want to spoil the joke.)
Personally, I've heard the cellphone "buzz" over the radio - picked up either by the radio stack or the audio panel - on the Cessnas I've flown. A minor annoyance every few minutes during a flight, but still, a distraction to the pilot. And there are claims airline pilots can hear them too in their radios - some may even say "And by the way, thanks to whoever left their cellphone on...".
But it's more for the FCC preventing use of cellphones (DoS of cell towers by causing interference). I suppose a terrorist would just need a few dozen cellphones and flights to take down significant portions of the cell network.
I suppose it's good that it's just data and SMS for the moment - air rage incidents would rise sharply had they done voice. Plus relaying data is far simpler than relaying voice (less latency constraints). Though, I suppose a major holdup for voice is negotiating the roaming agreements - airlines are probably salivating at the ability to ding people $5/minute for using their cellphones via the roaming agreemnts, while cell carriers are having difficulties because a domestic flight will then have them paying loads for roaming... -

Real Problem: Unknown Cause
It was irresponsible for the Independent to run the title as " Are mobile phones wiping out our bees?"
Colony Collapse Disorder (CCD) of bees could have a major national and worldwide impact this year on crop yields.
But is said right in the article: "No one knows why it is happening."
It also says:
"Now a limited study at Landau University has found that bees refuse to return to their hives when mobile phones are placed nearby. Dr Jochen Kuhn, who carried it out, said this could provide a "hint" to a possible cause."
Right now that is just speculation. Decades ago a study conducted in Denver suggested taht inner city children were more prone to cancer in areas of the city where there were higher densities of electrical transformers.
The next thing people knew, there were articles everywhere that high voltage power lines could cause cancer in children. (even though the original study had nothing to do with power lines). People became afraid to live near high voltage lines and property values dropped.
Eventually the original study was proven to be faulty. Decades of anguish by many thousands of people were caused by the faulty extrapolation of conclusions from the original faulty study (see link).

Interference is not an urban legend
TFA says:
Also: If real testing were done, and the nature of the problem fully understood, it would become obvious that airplanes could be designed or retrofitted with shielding and communications systems that would enable safe calling through all phases of flight. But that would cost money.
Real testing has been done. Unintended emissions from the phone have been identified as the culprit, not a deficiency in the navigation equipment. The aircraft's receivers are doing exactly what they are supposed to, responding to signals of certain frequencies arriving at the antenna. Once the phone pollutes the spectrum with spurious signals, nothing can protect the receiver. The shielding and filtering must be applied at the problem, which is the phone. Since the competitive consumer phone market demands the lowest possible cost, once a phone meets the minimum legal requirements they won't add another dime of product cost for further interference control.
Intereference does not occur every time, but when it does occur there has been a demonstrable cause and effect relationship. Start with this NASA case study(long pdf warning).
In July 2003, it was reported to the Federal Aviation Administration (FAA) that a cellular phone when turned on simultaneously interfered with three different aircraft GPS receivers, causing complete signal loss. The three GPS receivers were using three separate antennas, and were installed on a small aircraft. The phone was on, however, calls were not made during the incidents and subsequent tests. [emphasis added]
In an email message to the FAA, the company who owned the airplane reported the subsequent tests taken to prove a clear and convincing direct relationship between the phone being in ON-mode, and interference with the three onboard GPS systems. The company verified several times, in multiple flights over different days, that the interference problem could be recreated reliably in the air by having the phone turned on. The interference disappeared when the phone was turned off or covered behind a metal object, and re-appeared when turned on or brought into the open again. In addition, the company conducted tests at two different places to ensure that it was not dependent on location, and were able to reproduce the interference effects at both. The interference occurred when the plane was in the air, but not on the ground. Tests using other phones did not create interference problems on the same aircraft and systems.
Then consider this article from Spectrum. On page 3:
Our data and the NASA studies suggest to us that there is a clear and present danger: cellphones can render GPS instrument useless for landings. Clearly, the cause of the problem is that the FCC issues RF emission standards for consumer electronics, conferring only minimally with the FAA and with no formal consideration of the implications of those standards for the aircraft environment. For its part, the FAA relies on the airlines to initiate safety plans and, like other government agencies, defers to the FCC on questions of electromagnetic radiation.
And from page 4:
All in all, we found 125 entries in the ASRS [Aviation Safety Reporting System] database that reported PED interference. Of these, 77 were considered highly correlated, based on the description of observed PED use and interference occurrence.[emphasis added] The reports included cases of critical aircraft systems such as navigation and throttle settings being affected. Based on the random sample entries from 1995 to 2001, we estimate that the average number of reported interference events might be as high as 23 per year.
It's no conspiracy, and no urban lege

IEEE Spectrum article with recent test data
IEEE Spectrum had an article about this last year ( http://www.spectrum.ieee.org/mar06/3069 ); the authors actually sampled in-flight RF data and reviewed some related publications. They also discussed the current reporting methods for HED interference and discussed some of the reports. Bottom line for those that don't want to read the whole article: some cell phones and other devices emit innocuous signals that pose no significant danger, while _other_ cell phones and devices pose significant risks of interfering with avionic electronics, depending on the frequencies they use. This inconsistency alone is a problem. "Sure, you can use your AT&T phone, ma'am. I'm sorry sir, you have to turn your Sprint phone off or we're all going to die". The FCC and FAA do not work with each other (as a rule of thumb), so both the technical and regulatory issues can conflict with one another.
It's a good article for the layperson, I'd encourage reading it. -
For an article with *real* research done...
From the IEEE's Spectrum magazine last year, they actually measured RF signals on flights and reported on the results. No smoking gun where an accident was caused by a cell phone, but still interesting nonetheless (and no ads!). http://www.spectrum.ieee.org/mar06/3069

Two main programmer mindsets
I've worked with people with very focused high-level programming skills and found that while they could write mostly decent code, their code was also most likely to fail in production since they were completely mentally removed from concepts like disk-seek times or bandwidth constraints.
I'm not a great programmer, but I've always had a good "sense" (for lack of a better word) about technical things. I worked a bit at a company doing mid to high level (V)FoxPro programming. They put me on the least desired machine and I set to work. Within minutes I realized the machine was not running right, CPU at 100% or close to it most of the time. Turns out it was virus-infected (despite NAV, of course). I found the name of the EXE, renamed it in autoexec.bat before it loaded, then deleted same. Problem solved and the oldest 'clunker' became a quite acceptable computer.
I think this story illustrates the two broad classes of programmers. (1) those able to get a task done, no matter how nerdy or obscure (but who are pathologically incapable of documenting their work, or teaching others) [e.g. my co-worker who had used that computer for months or years without noticing the virus] and (2) those who are good at interface, optimization, and documentation but lack the penetrating power to solve the more difficult problems [e.g. myself -- I had to leave that job because I couldn't 'crack' the OO stuff].
Speaking to this thread's main question: both classes of programmer would need to understand some assembly, but for different reasons. Group 1ers would likely end up using it (or having to debug/change it) from time to time -- and it would be no big deal to them to learn it, use it, whatever. Group 2ers would likely want to know _when_ to use it, and probably get someone else to do that coding.
In the geek cred hungry world of /., not many would want to admit to being a Group 2er but I have no problem with it. For example, Group 2ers would also know when a Group 1er's code sucked, from a performance standpoint. Coders with a trailblazer mindset are rarely good optimizers.
BTW, in considering where Woz, Ciarcia, Kahn and Hertzfeld fit into this, I think they are Group 1ers who simply took an interest in Group 2 stuff. If you can learn both mindsets, you are one powerful programming dude, IMO. [Pity that 2ers like myself can't easily (ever?) become 1ers.] Most 1ers just want to get the job done and move on, yet so much can be learned after you think you have finished your program. [MS deserves props for realizing this and assigning a second unit to work on optimizing the code already working -- Win95 crap became slightly less crappy Win98 through this process (pdf)] -
Re:So I don't get it...
Yes, you could see in the video that they used a 3rd party driver. However, was it really CLEAR that the exploit only existed for the 3rd party driver? Maynor and Ellch certainly did NOT dwell on this -- they in fact spent more time saying they enjoyed doing this because Mac users were "smug."
It's no surprise they failed to give Apple exploit code or specifics. What bugs Apple did find, were through their own code audit.
The "exploit" demo was clearly faked. They speak of and show a third party wireless card with a USB interface, yet looking up the vendor from the MAC address shown on the Apple laptop screen shows an Apple card. The "facts" don't add up. They lied. They may have actually found a bug that could cause a crash, but it is pretty obvious the reason they couldn't produce the exploit code they claimed to have written was they didn't actually have any.
It is easy to check out the MAC addresses used by network hardware.
http://standards.ieee.org/regauth/oui/index.shtml
Certainly OS X has and has had some bugs that could potentially be problems.
Apple seems to be doing it's best to deal with any found, and appears to have taken security seriously for a long time.

As you say, contracts can stop this. IEEE's magazine Spectrum had an article about a group of communities in northeast Utah who were creating a "A Broadband Utopia" to be owned by them. It's speed will be capable of 50 Mbps, it can even be 100Mps. Though the infrastructure is owned by local governments, it is open, meaning anyone who wants to and has the capabilities can offer services using the infrastructure. These services be any combination of internet access, phone service, tv, or other services that come up.

Re:NAT discussion wasn't thorough enough
And even there, there is a workaround that can be employed with the use of a 3rd party that doesn't block incoming connections (though I haven't heard of any P2P protocols currently use this method in the wild).
Skype (which, coincidentally, was written by the same people who wrote Kazaa) uses some of those workarounds to punch through NAT firewalls. I do not know if Kazaa uses them, but the authors of Kazaa could have certainly done so.
The point of all this being, you can share files, without accepting inbound connections. You can download files from others without accepting inbound connections. And you can participated in the P2P network (communications, searches, etc) and all of the above, without your P2P program knowing your public IP address.
But P2P works better if it has access to your public IP address, and you can accept inbound connections. Hence some P2P applications will complain if they detect that they are NATed and ask for your public IP. Some will auto-detect you public IP. Others will not only autodetect your public IP, but if you have a UPNP-capable router, will automatically detect or otherwise set up appropriate holes in you NAT firewall (later versions of Azeurus do this, I believe) to forward inbound connections. And, as aforementioned, Skype uses NAT-busting techniques to bypass setting up proper forwarding rules altogether. Skype's ability to get past firewalls is actually somewhat frightening...
Although the original design of the internet was based on the assumption of a static one-to-one mapping of computers to IP addresses, this is not the case today. DHCP means that the mappings are not static, and NAT means that the mapping isn't one-to-one (indeed, a sufficiently sophisticated NAT setup could be many-to-many, although such would be unusual). Even MAC addresses aren't really unique--it is quite common to set up interface failover by spoofing the MAC address of the failed NIC. Identifying a computer uniquely is a very tricky process--the common means of doing so rely on these broken assumptions. The uncommon means (specifically, searching for evidence of clock drift in timing parameters) are, well, not commonly used, and have higher false positives (due to sensitivities to temperature and the low precision of clock drift measurements). And none of this can be used to show that a particular person was doing anything at any point in time.
From my limited experience with expert testimony, many expert witnesses, although experts in their field, are not experts at being witnesses. It's a way for a university professor to pick up more money on the side with easy consulting work, especially if hired by a petitioner under the expectation of a weak defense by the respondent. In such a case, speed and cheapness are prized above thoroughness and accuracy, and actually being deposed by a lawyer who has been prepped on the sorts of questions to ask would be quite the surprise. Dr. Jacobson appears to have been caught with his pants down, giving a slap-dash report which is clearly biased in favor of the side which hired him. Although he isn't a member of any regulatory body, I would be surprised if he wasn't a member of the ACM or the IEEE Computer Society, and in violation of their respective codes of ethics (specifically, ACM 1.2, 1.3, and 2.5, and IEEE 2, 3, 7, and 9).

fast breeder reactors
Me too, but most with regard to all of the barely used nuclear fuel rods languishing at reactors all over the country. There's a ton of energy left in them, and by burning up the actinides you're left with waste that's 'hot' for a faction of the time.

stop gap measures
Then I would say that the optimal solution is incandescent bulbs and nuclear power. So let's get the move on! Mandate nukes, not some stop-gap measure that requires a whole new level of the old recycling boondoogle.
Isn't nuclear power a stop gap measure? And one that creates and leaves more problems than they solve? In the US the Bush admin wants to use Yucca Mountain as permanent storage, well for 10,000, when the halflife of some of the waste is millions of years. On top of that Yucca is a seismically active region, having had earthquakes in the area, and has a volcano not too far away.
Someone can then say the waste can be reprocessed, as the French do. IEEE's magazine IEEE Spectrum has an article in the Febuary 2007 issue, Nuclear Wasteland by Peter Fairley asking "The French are recycling nuclear waste. Should other countries follow suit?" He brings up problems reprocessing creates including reprocessing concentrates high level waste that's hotter and harder to handle than waste that isn't reprocessed.

Fine paper, but why not quote all of PAMI ?This is a nice paper by respected researchers in AI+Vision, however pretty much the entire content of the journal this was published in (IEEE Pattern Analysis and Machine Intelligence) is up to that level. Why single out that particular paper ?
Interested readers can browse the content of PAMI current and back issues and either go to their local scientific library (PAMI is recognisable from afar by its bright yellow cover) or search on the web for interesting articles. Often researchers put their own paper on their home page. For example, here is the publication page of one of the authors (I'm not him).
For the record, I think justifying various ad-hoc vision/image analysis techniques using approximations of biological underpining is of limited interest. When asked if computer would think one day, Edsgerd Dijkstra famously answered by "can submarine swim?". In the same manner, it has been observed that (for example) most neural network architectures make worse classifiers than standard logistic regression, not to mention Support Vector Machines, which what this article uses BTW.
The summary by our friend Roland P. is not very good :This versatile model could one day be used for automobile driver's assistance, visual search engines, biomedical imaging analysis, or robots with realistic vision
- There already exist working automated driving software. The december 2006 issue of IEEE Computers magazing was on them last month. Read about the car that drove a thousand miles on Italy's road thanks to Linux, no less.
- Visual search engine exist, at the research level. The whole field is called "Content Based Retrieval", and the main issue is not so much to search, but to formulate the question.
- Biomedical image analysis has been going strong for decades and is used every day in your local hospital. Ask your doctor !
- Robotic vision is pretty much as old as computers themselves. There are even fun robot competitions like robocup.
I could go on with lists and links but the future is already here, generally inconspicuously. Read about it. -

Heavy-handed managementSoftware becomes hard when heavy-handed management decisions are made to give too much emphasis to a particular software tool or methodology.
- An expert programmer (working with human factors experts) can prototype the new system in a cross-platform scripting language (doesn't matter which one), then can identify the objects
- a software team can refactor the system once again in an object-oriented language (doesn't matter which one).
- Finally, a period of benchmarking can identify the bottlenecks which can be refactored one last time, plus the hardware and Operating System decisions can be made based on the available hardware at the end of the software development cycle.
An approach like this would probably have been helpful in FBI's failed $100 million debacle the Virtual Case File system

Re:Yeah, if you only run one program at a time..
RapidMind has been designed to do what you speak of.
You can write on multicore processors using C and specialised libraries that were designed for multicores.
Its a pretty neat and should make multi-core development easier.
Theres some videos on their website of some pretty interesting things they done using Cell.
http://www.rapidmind.net/samples.php/
(note: these programs were done in as little as 3 weeks)
Some on Spectrum at IEEE http://www.spectrum.ieee.org/jan07/4837/1
According to some artices i read (hell knows what the links were again), it will be available for PS3, actually running under YDL.
Not sure if it is true, but it will be added to the devkits, it was meant to be added before release, but they decided to spend more time on it (possibly to their disadvantage with some developers being "left on their own"...pfft lazy if you ask me, not true programmers in my eyes! A true programmer would strive to get code working on anything!) -
Re:internet regulations
And it's amazing all this happened while the internet was unregulated. Imagne what would of happened if it had been regulated.
Pretty easy... just look at cable TV.
Amazing how all the cable people required monopolies to run cable but no one needed a monopoly to run high speed internet.
Actually companies did need, er used a, monopoly to offer broadband. Except for Wifi, WiMAX, ie all landline providers do have monopolies by which they are able to offer broadband. This is true whether the ISP is cable or telco. The only way these companies would be willing to spend all the money to build the infrastructer was if they were granted exclusive rights. They have however outlived their purpose. To tell the truth, though I am a Libertarian, I believe local infrastructure should be locally owned. Either government, coop, or some local organization. The IEEE's Spectrum has a good article on how some communites in northeastern Utah are creating "A Broadband Utopia". I'd like to see more things like this. Falcon

Software validation.
The answer is simple.
Proprietary closed source software cannot be validated. You cannot trust that it will always work properly, because the source is not available for validation.
http://www.fda.gov/cdrh/comp/guidance/938.html
http://standards.ieee.org/catalog/olis/se.html
http://hissa.nist.gov/HHRFdata/Artifacts/ITLdoc/23 4/val-proc.html#233_SEC
http://www.access.gpo.gov/cgi-bin/cfrassemble.cgi? title=200621
Software pricing has nothing to do with it. The validation process in regulated environments will cost many times more than the actual value of the software itself. The cost of the actual software is trivial.
Closed source software has no future in regulated, mission-critical applications.
Belief and faith are irrelevant. -
Re:I'm pretty sure[I'm pretty sure] that no scientist has ever proposed singularities as the source of ball lightning.
I'm pretty sure that Dr. Pace VanDevender, Vice President Emeritus of Sandia National Laboratories, with a Ph.D. in physics from the Imperial College of Science and Technology, University of London, counts as a scientist. He also has proposed singularities as the source of ball lightning, although he's not exactly confident (source requires subscription):
VanDevender himself knows it's on the wild side. "This is a long string of what-ifs," he admits, "it's very loosey-goosey." He reckons the odds of mini black holes existing are 1 in 10, the odds of catching one, maybe 1 in 1000, if he's optimistic. And that's what he wants to do: catch a black hole. "After stewing on it for years, I decided I did not want to die without knowing whether it was or was not real," he says.

Re:Question
What about this: I copy a HD-DVD to my harddrive. Then I find the decryption key for it. I decrypt it and convert it to another format. Couldn't I then distribute it without them knowing what player was used?
That's exactly the scenario that has been characterized as the fundamental weakness of AACS, the encryption mechanism of both HD-DVD and Blu-ray. Congratulations for finding this out in less time than the engineers who designed it.

Re:Can you handle ROI?
I think that you misread me. That's the renewable energy subsidy if we gave wind power the same 'subsidies' that are 'given' to nuclear power. This system was set up by the Price-Anderson act
Thanks for the link. I didn't know the industry paid for insurance. I went ahead and both saved it to my hdd and bookmarked it.
Many people have battery banks to store the energy their solar, wind, or hybrid systems generate.
Don't get me wrong, but while people do it, it's not globally economic to do so. Most people who do these systems do so to avoid the expense of running line power to them. Meanwhile they do things like run special refridgerators and use hydrocarbon method of accomplishing tasks such as heating their home, water, and cooking. For example, solar power will make sense much more quickly in Sunny california with high electricity costs than ND with it's cheap electricity.
First, North Dakota isn't good for solar as you say but the state is a great site for Wind Gennies. As is SD and Minneasota. MN, where I live now, generates several megawatts of power by Wind Gennies. While it may be mostly those living off the grid in the US who's doing it, it's not the only place solar panels and batteries are used. The same think is done in the third world. In Africa one or more NGOs are going into small villages where they setup solar panels and battery backups to power lights, radios, refrigs, small tvs, and such. The lights allow children to read and do homework for school while it's dark. The refrigs allow medicine to be stored, and the radios and tvs keep the people informed about the world. They are also used for educational purposes. The IEEE's Spectrum had an article about how some people started a business in South Asia building solar energy systems they then sold in remote locations and other places without electricity. The business created jobs manufacturing them, it also allowed those who bought a system to improve education as well as earn more money. One example was of a person who ran a repair shop, he was able to use lights so he could work when it was dark thus he increased his income. In another Spectrum article they described how a group of EEs went into a remote village; in Cambodia, Thailand, or Veit Nam, I don't recall which, and setup a transceiver with a tower for the antenna so they could have radio communications with the outside world. Using a "home built" PC and a bike converted into a generator, the group was able to offer the village internet access as well as voice radio. If they wanted to power the system all they had to do was pedal the bike. If they had setup a solar panel the bike could of been for backup.
Fact is you only have a few years to make back the investment because the batteries degrade, eventually needing replacement.
Sure, the batteries eventually need to be replaced, however batteries today last longer than the deep cycle batteries of yesteryear, and they're cheaper. Batteries can now have 10 year warranties with 20 year life expectancies. Here's one with 7 year replacement(pdf), and 3 year prorated warranty for a total of 10 years. As for solar panels, they can be rated 20 years or more. The same with the chargers.
Ok this site has batteries inteneded for renewable resources for sale. The L-16HC seems to be the best deal, for the amp-hours. It's a 6 volt battery that has 420 amp-hours of capacity. That's 2520 watt/hours. Divided by it's cost of $288, that's $114 per kw/hour of capacity, and it's only rated for 3-6 years of 20% daily discharge.

Re:Not at the fault lines
Scientists have done studies about these issues. One paper can be found here. Digging holes in the bottom of the ocean is relatively easy under current technology. The record-setting Chevron well, called Jack 2, which is 175 miles off the Louisiana coast, is more than five miles deep, including more than a mile of ocean depth.

Instead add neon lite to PC for better performance
The recipe for the electrolyte in capacitors is kept as a big secret similar to the secret ingredients in the sauce at a restaurant.
Chinese industrial spies stole a fake formula from a Japanese company, and started making capacitors, and the rest is history.
A combination of a smaller solid cap with good HF performance together with a cheap and large electrolyte further away, but with better LF performance will beat the solution in the article.
I use the power supply from a 25 old HP HDD as a lab supply. It has huge electrolytes that still deliver great performance.
You will probably get more performance improvement by adding neon lights to your case.
