10 years ago you might have had to improvise, but today you can get cheap high quality antennas and amplifiers that is a lot better than a USB dongle in an old satellite dish.
If you really need big distances, you can use an old 12' sattelite dish, but otherwise stick to the formula above. It will save you a lot of time and trouble.
I have reliable links over 10km with 10mW running at 50Mb/s
Imagine how awesome it would be for humankind if all copyrighted material could be accessible to all. All books, art, movies, music etc would be available with a click.
Here is how we do it: Make a global library where everyone can donate a copyrighted work. The library then manages the copy, and make sure only one person can use it at a time. This should be managed like Netflix (which also btw distributes copyrighted material)
Example: 1. You rip a DVD to mp4 and upload it, 2. then place the original in a drawer marked "Archive copy of donated work". 3. The library registers that it has the license. 4. Now anyone could download the mp4 to have a copy on the disk, but needed to check out a license to actually view it.
If a second person donates the same work, no upload is necessary, so skip (1). Only (3) is required (i.e. licensecount++)
I am sure the with the efficiency of the net, the cost to build up this library to contain everything would be much smaller than the cost to operate current brick and mortar library.
Also, all the hard software parts is pretty much done/solved: MythTV, Bittorrent, Youtube, and the Netflix algorithm.
Tomato is not really open source. It is open source except for the UI. DD-WRT is just a branch of OpenWRT that costs money. It is free for home use however.
Use OpenWRt; It is open and free. If you want simplicity, use X-wrt, which is basically OpenWRT with a web based UI. It does not use the latest version of OpenWRT, but is very stable. It includes a smörgåsbord of modules to add with a simple mouse click.
Ah.. Indian schools at work. Seriously, you should read a book or two on COMEDY; once a year. Just casually flip through it and try to smile.
Anyway, I got my degrees from European universities, and I am always looking for good book recommendations. Can you please recommend some books you read recently. Who is is Eva Longoria or Patteniere BTW??

Water Ice On Mars
·
· Score: 4, Interesting
First, I think the best evidence so far that this is water is not this picture, but the fact that the Mars Orbiter's spectrometer determined that that is was a lot of hydrogen in the ground near the poles.
That some white stuff vanishes is poor evidence. They need to get the white stuff in an oven and test it.
Let's assume it is water. What really puzzles me is how clean the water is. It is covered with what would make a dirty mud if it ever melted together. Also on earth, you never have clean water if you have flash floods like what you see as a result of a volcanic eruption or meteroid impact. You only have clean water/ice in snow and still lakes/oceans. This implies: 1. The ice has not melted after the dust blew over it.(A long time) 2. It used to be a lake/ocean or snow
So the purity of the ice might be a bigger discovery than the fact that it is ice there.
An exiton is just an electron "bounced" out of its location, leaving a positively charged hole behind. The negative electron and the positive hole (the imaginary particle) pair forms an "exotic atom" state similar to a hydrogne atom, but with a much lower binding energy and a much larger size.
This behavior is the standard behavior semiconductors.
It appears the difference here is that when the electron/hole pair reunites, a photon is emitted.
This appear awfully close to what an LED is, and the article is void of any information to distinguish this component from the LED.
TFA describes a project in complete disarray and a failure on all level. Despite this level of failure, TFA is pretty much anecdotal. TFA has no hard metrics or any other solid data to support the anecdotal conclusions. It is very possible it is accurate, but if a project is a complete mess, it should be easy to get good solid metrics that document this.
The fact that the author of TFA has none of this makes his assessment not only worthless, but places his work in the same category as the mess he was assessing.
If you need to slaughter a project, you need to: a. Have a measurable set of goals for the project b. Measure the current status against the goals c. conclude status.
It would suffice to give a list of the different functions with number of showstopping defects for each function together with a description of the most glaring defect in each of the functions. Just pulled out of the bug tracking system verbatim would do. Example of glaring defect: "When the user push the OK button on screen XYZ, the server crashes, and all the data is lost. There is no workaround"
Sen. Orrin Hatch (R-Utah) suggested Tuesday that people who download copyright materials from the Internet should have their computers automatically destroyed.
But Hatch himself is using unlicensed software on his official website, which presumably would qualify his computer to be smoked by the system he proposes.
The senator's site makes extensive use of a JavaScript menu system developed by Milonic Solutions, a software company based in the United Kingdom. The copyright-protected code has not been licensed for use on Hatch's website.

The Norwegian Standards committee was also almost unanimously against the OOXML. Then the Bill & Melinda Gates foundation offered a few hundred million $$ to various pet projects of the Norwegian prime minister such as a Svalbard seed bank http://en.wikipedia.org/wiki/Svalbard_Global_Seed_Vault as well as vaccination of kids in poor countries.
To everyones big suprise, the government set aside the No vote, and ruled by fiat that Norway would vote Yes.
But then again, why care about a petty little standard and some petty corruption when you can save the world.
I would recommend against a career as a software developer as well. Almost all companies that are successful and employ SW engineers are selling something else as their main product, typically some HW. (Printers, routers, wi-fi etc). I can also include hospitals, lawfirms, banks etc.
There are two problems working for this kind of companies for a SW engineer; where the boss is and will always be a HW engineer (Or a physician or an attorney etc) 1. You can *never* be promoted to the top of your company. 2. You are *always* second in line for funding and other resources. 3. Sales people frequently close sales with offers like: "Buy this box, and we will throw in the SW for free" (Because they basically think SW is free), and the SW departments revenue is eroded away.
There are a few exceptions to this, and that is MS and Google, but they probably hire 1% of SW engineers.

Multiple comments here on/. tells the music industry to adapt to the 'new world'. This is like throwing a lobster in boiling water, and telling it to adapt.
The business model for the music industry has always been: 1. Buy expensive recording and vinyl pressing machines. (The price on this equipment gives them a de facto monopoly on production) 2. Pay musicians a song for their work (maybe this is where the expression comes from?) 3. Sell disks for as much PROFIT as possible
In the 'new world' there is no monopoly and ipso facto no music industry.
Some perspecitve: A Magnetar has a magnetic field of 10 GigaTesla. That is a field energy density of 4x10^25 J/m^3. That equals an E/c^2 mass density 80kg/cm^3 or >10^4 that of lead.
The reason Europe decided to build Galileo as a direct civilian alternative to US' GPS was to prevent the US from shutting down all navigation in case of a conflict. TFA says that the new (US military) GPS now will have 500x transmit power, and also transmit a new civilian signal (L1C) to be fully compatible and interoperable with EU's Galileo.
I wonder if the capability to "interoperate" with the Galileo system also includes "Jamming". Seems like the satellite could produce a good military GPs signal while at the same time transmit a corrupt L1C signal to "interoperate" with the Galileo system.
Normal RGB displays do not span the colorspace the eye can see. Just like good printer need more than 3 color ink to make good photograps, good display need more than Red, Green and Blue dots to span the whole colorspace of the eye. No matter how many bits you put behind each color, you can not improve this fact.
Brief explanation: RGB colors are designed to match the human eyes sensitivity for the three primary colors. Each color cones spectral sensitivity partly overlaps the others. The RGB display therefore can not excite the Blue cone exclusively nor the Red cone. A new display with the following colors could get close: Violet@400nm, Blue@430nm, Green@530nm, Orange@650nm and DeepRed@700nm

it is cheap and wets most metals (good heat transfer)
it is a little reactive, so recycling would need some special handling.
