Currently, price is not the problem in these smaller sized displays. If you find a 20" LCD TV still too expensive, I fear you will find another relatively new product too expensive as well. LCD prices go way up at about 30". Check the prices for 32", 36" and 42" LCD TV and you know the meaning of of expensive....
It is only done to cover things up. A sincere manufacturer can just give the actual horizontal and vertical pixel counts. Hiding these behind acronyms and using nonstandard counting methods (like counting the R, G and B dots separately when calculating the "six million pixels" number) is only done by swindlers.
Apparently you can claim almost anything in adverts in many countries. In the Netherlands there are some quite firm restrictions, and a commission where anyone can complain about an ad. Probably in other countries you would have to use the legal system, and nobody would bother.
Memory tag bits are nothing new; Burroughs 6000/7000 systems had these (3 bits per word even) in the 1960's. With 3 bits you can also tag a word to contain instructions, and the type of data (integer, float etc).
but I really don't want any government organization that involved in anything related to the net
You are going to be worried. The net has outgrown its infancy and it is being monitored and policed by the government just like the real world. (of course much of that is caused by abuse of the freedom)
These were small companies, not mega-corporations that can pay a 5-million dollar fine and continue. Also, this is a fine, not a tax. They will of course have a big problem when they continue and get caught again.
The difference is that these countries do not have the money to spend on such luxury items. Of course they spend money on lots of other unnecessary things, like conflicts, but that is a fact of life.
>Moreover this region is not linked to the pacific ocean tsunami network. There are no bouys here.
Why do you need a tsunami detection system when an earthquake detection system is already in place? What you would have needed is an alarm system, something that can be used to quickly alert people along the coast. A common contact number or e-mail address where a warning could be sent that all local radio stations will broadcast, for example.
It was wellknown to all seismic centres around the world that the quake had happened, but they had no way to warn people to stay off the shores. A system with detection bouys would not have helped, it was *known* that this would happen. (apparently even the news that Thailand was hit was still no reason to try to more actively warn India and Africa)
A real digital scope has logic to display periodic signals that are above the sampling rate, by sampling the signal at different points over time. That would require hardware trigger and sync.
Flex-radio is designed for narrowband use. With the PC-soundcard as an A/D converter it is limited to 20-40 kHz bandwidths. With the faster hardware mentioned in this article it is possible to receive wideband signals.
The device is mainly a fast analog-to-digtal and digital-to-analog converter, with USB interface. It allows you to quickly readout a couple of analog signals using a PC, and to generate some analog signals under program control.
With some additional radio hardware (supplied on daughterboards) you can convert a certain frequency band into analog signals that are then fed to the converters. With proper software you can use this as a radio that does not have a tuning knob but can be tuned in software and/or to receive an entire radio frequency band and process all the signals in parallel.
For example, you can draw a picture of the signal strength for each frequency, plot this versus time. Or you could write software that receives all FM stations in your area simultaneously and converts their broadcasts to streaming audio channels.
Consider that putting such things on a PCI board also has some disadvantages. - the board will be inside the noisy environment of a PC. not really what you want for a receiver. - PC buses tend to be short-lived. PCI is on its way out, so in 5 years everyone will be asking how you could design a card for which no motherboards are available (it happened to ISA, MCA and EISA before!)
To make a digital oscilloscope, you need more than A/D converters. Input amplifiers/attenuators, some trigger/sync logic, and a lot of software seems to be the minimum. So while this is possible, it is similar to saying that a continuous-coverage (cable) tv tuner can easily be turned into a spectrum analyser. People have done that.
This is not going to work very well. Use one of those orbit tracking programs or websites and see for yourself how small the area of the earth is that is visible at one time from the space station. It will take 100 minutes to see a band-shaped area of the world, and several hours to see everything.
It is difficult to launch something into a secret orbit, because anyone in the US with a receiver and PC can listen back on the NAVSPASUR radar that the government uses to track satellites. This lets you determine orbit parameters from your own home.
For us, this problem passed away by itself several years ago. In or before 2000, we sometimes got mail with TNEF attachments, but it seems that the vast majority of Outlook users have long switched to HTML, which works OK with Mozilla. We get maybe one TNEF attachment a year.
Of course some companies, e.g. SuSE, have been offering this for some time. A dedicated distribution for a corporate mailserver, even with Exchange-compatible protocol, and a setup and configuration center to manage it all.

What is your problem with LCD brightness? I have two relatively new LCD tvs and both of them are, if anything, too bright rather than too dim.

In most countries the legal system does not work that way.

But not from noise on the supply, and the highspeed databus.

It is not intended for that kind of customer.

Ethernet? Gigabit ethernet ports are becoming common on PC and laptop systems. There are more systems supporting ethernet than USB.

I've not seen anything else that has this feature
But did you look? I don't know about Thunderbird, but the classic Mozilla does have this feature.
Ok but why do you need to develop new engines when you can buy RD180's?
And even the Saturn V shut down 1 of the 5 stage engines near the end of each burn to reduce the thrust.
