Independencia del ciberespacio
A Declaration of the Independence of Cyberspace
by John Perry Barlow
Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather.
We have no elected government, nor are we likely to have one, so I address you with no greater authority than that with which liberty itself always speaks. I declare the global social space we are building to be naturally independent of the tyrannies you seek to impose on us. You have no moral right to rule us nor do you possess any methods of enforcement we have true reason to fear.
Governments derive their just powers from the consent of the governed. You have neither solicited nor received ours. We did not invite you. You do not know us, nor do you know our world. Cyberspace does not lie within your borders. Do not think that you can build it, as though it were a public construction project. You cannot. It is an act of nature and it grows itself through our collective actions.
You have not engaged in our great and gathering conversation, nor did you create the wealth of our marketplaces. You do not know our culture, our ethics, or the unwritten codes that already provide our society more order than could be obtained by any of your impositions.
You claim there are problems among us that you need to solve. You use this claim as an excuse to invade our precincts. Many of these problems don't exist. Where there are real conflicts, where there are wrongs, we will identify them and address them by our means. We are forming our own Social Contract. This governance will arise according to the conditions of our world, not yours. Our world is different.
Cyberspace consists of transactions, relationships, and thought itself, arrayed like a standing wave in the web of our communications. Ours is a world that is both everywhere and nowhere, but it is not where bodies live.
We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth.
We are creating a world where anyone, anywhere may express his or her beliefs, no matter how singular, without fear of being coerced into silence or conformity.
Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are all based on matter, and there is no matter here.
Our identities have no bodies, so, unlike you, we cannot obtain order by physical coercion. We believe that from ethics, enlightened self-interest, and the commonweal, our governance will emerge. Our identities may be distributed across many of your jurisdictions. The only law that all our constituent cultures would generally recognize is the Golden Rule. We hope we will be able to build our particular solutions on that basis. But we cannot accept the solutions you are attempting to impose.
In the United States, you have today created a law, the Telecommunications Reform Act, which repudiates your own Constitution and insults the dreams of Jefferson, Washington, Mill, Madison, DeToqueville, and Brandeis. These dreams must now be born anew in us.
You are terrified of your own children, since they are natives in a world where you will always be immigrants. Because you fear them, you entrust your bureaucracies with the parental responsibilities you are too cowardly to confront yourselves. In our world, all the sentiments and expressions of humanity, from the debasing to the angelic, are parts of a seamless whole, the global conversation of bits. We cannot separate the air that chokes from the air upon which wings beat.
In China, Germany, France, Russia, Singapore, Italy and the United States, you are trying to ward off the virus of liberty by erecting guard posts at the frontiers of Cyberspace. These may keep out the contagion for a small time, but they will not work in a world that will soon be bl

AVI and DivX tools

1. SubtitlesSynch
SubtitlesSynch is a small and easy to use tool that enables the user to synchronize the time of a subtitle (.sub/.srt) file by entering the time difference between the video and the subtitle file giving you a new subtitle file synchronized with your video.
It automatically open with the previous selected subtitle file and has an option to synchronize only for a specific time slice (good for commercial breaks). The program interface itself is pretty much self explanatory. Load the subtitle file, if the subtitle is slower than the movie character is speaking, then you need to select “Add time” and set the time offset in seconds and milliseconds, minutes and hours probably won’t be required. If the subtitle is too fast, then select “Reduce time” to slow down the subtitle.
Download SubtitlesSynch 
2. Easy Subtitles Synchronizer
This is a much more advanced utility and as well as containing several options to repair, synchronize and adjust your subtitle files, Easy Subtitles Synchronizer can also allow inserting and editing of individual lines of subtitle text. This can be achieved with the option to load the video file the subtitle is for so the lines can be checked against the video without leaving the program.
Go to File -> Open Subtitle File to load an SRT or SUB file for editing and if the video file has a matching name excluding extension, it can be loaded as well. It can also be loaded manually. Then you have the ability to adjust several timing options from the tabs, including; the time of the first and last subtitles, manual synchronization of specific subtitles, move or change the starting point, extend the full duration and manually or automatically set the frames-per-second for the file. There’s also around 10 fixes that can be applied for common issues.
Download Easy Subtitles Synchronizer 
3. Subtitle Workshop
What will make Subtitle Workshop a valuable tool for many users is the sheer amount of subtitle file types it supports, around 30 different formats can be loaded in, edited and saved out again. In addition to editing, there are other powerful options such as spell checking and translating the text between different languages, and a search option which opens a page at with the query results.
The options to adjust and synchronize the subtitles are found in the the Edit -> Timings menu and there are several to choose from. The simple menu option to shift the subtitles forwards or backwards in time by 100 milliseconds might be all that’s required for some users, although you can also manually or automatically set duration limits, expand or reduce on screen display times, more precise control over inserting positive or negative delay times and adjust the time between the first and last spoken lines. All of those options can be applied to all or just selected subtitles. The video file itself can be opened in the window for a more visual inspection of the accuracy of your adjustments.
Download Subtitle Workshop 
4. SubMagic
SubMagic is quite a powerful subtitle analyzing, editing and synchronizing tool, but is also quite easy to understand and use. The program is also able to show the video file while manually adding, deleting or editing each subtitle if necessary. The Analyze tab can check and give information about potential errors, and the Fix Errors tab can apply around 25 different fixes to make the subtitle file more compliant.
SubMagic supports SRT, SSA, SUB, SMI and TXT files and there are a couple of tabs to to change sync settings; Framerate will allow you to switch from NTSC2PAL or PAL2NTSC quickly and easily to match the output video, and the Synchronize tab has options to move a selection or all subtitles backwards or forwards in time, and stretch or shrink the timing of the whole file or a selection. Simply enter the seconds and milliseconds and press the button, then you can go to the Movie tab and check to see it’s correct when overlaid onto the video.
Download SubMagic 
5. Subtitle Framerate Changer
Subtitle Framerate Changer is a plain a simple tool that allows you to change the timing of SRT subtitle files using either a positive or negative time adjustment, or altering the the framerate of the subtitles. A different framerate on the video and SRT file could account for synchronization problems.
The program also allows the batch changing of the framerate for multiple files at once if you have many subtitles with the same problem. To adjust a single file simply browse for it and select the output folder, then either choose the Change framerate option and set the desired frames-per-second for the saved SRT file, or the Set delay will allow the positive or negative delay in milliseconds for all the subtitles in the file. The program is only 215K and a portable executable.
Download Subtitle Framerate Changer 
6. Jubler Subtitle Editor
A requirement for Jubler to function is the Java Runtime Environment as it’s a Java based program, which will require downloading during the setup if you don’t already have it. The program can display a video preview of the subtitles overlaid onto it, but you need to have the open source MPlayer on your system to do so. Jubler also has a spell checker and translate option.
There are several options in the Tools menu to adjust the timings of the subtitles with Synchronize able to change the index offset, Shift time will move the selection forwards or backwards in time, Recode time allows the changing of the default subtitle framerate, and Time fix can adjust the on screen time of each piece of subtitle text. Each option can be applied by time range, user selection or by marked colors.

Front Side Bus & PCIExpress guide
There are three main buses in most computers:

1) PCI Bus- The PCI bus connects your expansion cards and drives to your processor and other sub systems. On most systems the bus speed of the PCI bus is 33MHz. If you go higher than that, then cards, drives, and other devices can have problems. The exception to this is found in servers. In some servers you have a special 64-bit (extra wide) 66MHz PCI slots that can accept special high-speed cards. Think of this as a double sized passing lane on a major road that allows higher cars to go through. For information about PCI Express please see the PCI Express Guide.

2) AGP Bus- The AGP bus connects your video card directly to your memory and processor. It is very high speed compared to standard PCI and has a standard speed of 66MHz. Only one device can be hooked to the AGP bus as it only supports one video card so the speed is better compared to the PCI bus, which has many devices on it at once.

3) Front Side Bus (FSB) - The Front Side Bus is the most important bus to consider when you are talking about the performance of a computer. The FSB connects the processor (CPU) in your computer to the system memory. The faster the FSB is, the faster you can get data to your processor. The faster you get data to the processor, the faster your processor can do work on it. The speed of the front side bus depends on the processor and motherboard chipset you are using as well as the system clock. Read on for more information about the Front Side Bus later in this article.
Bandwidth PCI Express: 1x, 2x, 4x, 8x, 16x and 32x all have much greater bandwidth than basic PCI.
Common Buses and their Max Bandwidth
PCI132 MB/s
AGP 8X2,100 MB/s
PCI Express 1x250 [500]* MB/s
PCI Express 2x500 [1000]* MB/s
PCI Express 4x1000 [2000]* MB/s
PCI Express 8x2000 [4000]* MB/s
PCI Express 16x4000 [8000]* MB/s
PCI Express 32x8000 [16000]* MB/s
USB 2.0 (Max Possible)60 MB/s
IDE (ATA100)100 MB/s
IDE (ATA133)133 MB/s
SATA150 MB/s
Gigabit Ethernet125 MB/s
IEEE1394B [Firewire 800]~100 MB/s*

* Note 1 - Since PCI Express is a serial based technology, data can be sent over the bus in two directions at once. Normal PCI is Parallel, and as such all data goes in one direction around the loop. Each 1x lane in PCI Express can transmit in both directions at once. In the table the first number is the bandwidth in one direction and the second number is the combined bandwidth in both directions. Also please note that in PCI Express bandwidth is not shared the same way as in PCI, so there is less congestion on the bus.

Update: Table above contains speeds for PCI Express 1.0 bus. 

For PCIe version 2.0, multiply all bandwidths by 2. 
For example a PCI Express 2.0 16x slot has a max bandwidth of 8000 MB/s one way or 16000 MB/s both ways.
* Note 2 - Firewire 800 has a bandwidth of 786.432 Mbit/s this converts over to between 98 and 99 MB/s.
PCI Express 2.0 runs twice as fast as PCI Express 1.0 or 1.1. However, there is currently no advantage to using a motherboard with PCI-E 2.0 slots, as no card out yet can take full advantage of a PCI-E 1.1 or 1.0 slot. (To my knowledge, there isn't any major difference between PCI-E 1.0 and 1.1. The PCI-E slots on most motherboards unless they're new chipsets like X38/X48/780 are 1.1.) And no, PCI-E 2.0 slots are not called PCI Express X32. They're still PCI Express X16 slots.
Increased bandwidth can be equated into increased system performance. We've long known that to get the most out of your processor you need to get as much information into it as possible, as quickly as possible. Chipset designers have consistently addressed this by increasing Front Side Bus speeds. The problem with this is that front side bus speed increases the speed of transfer between the memory and CPU but often you've got data that's coming from other sources that needs to get to the memory or CPU like drives, network traffic, video, etc. PCI Express addresses this problem head on by making it much faster and easier for data to get around the system.

Q-A Common Questions about PCI Express

Q:Is PCI Express Faster Than PCI?
A:PCI Express is much faster than PCI. For 1x Cards it at least 118% faster. When you compare PCI Express video to PCI Video the difference is enormous: PCI Express 16x video is over 29x faster than PCI Video.

Q:Is PCI Express Video Faster than AGP Video?
A:Yes and No. A 16x PCI Express connection is at least 190% Faster than AGP 8x but this is the connection between the system and the video card. You use the connection the most when your video card is low on memory or when the game you are using uses a Direct X or Open GL feature that isn't supported in hardware.

So, what this means is that in terms of real world performance there may not be a huge difference between AGP and PCI Express if you are talking about identical chipsets. Unfortunately this is very hard to prove because graphics chipsets are designed either for PCI Express or AGP. If you have a card that is available in both forms then you have a graphics chipset that was designed for PCI Express and has a special bridge chip installed to let it communicate with the AGP bus. The short of this is: if two cards of the same chipset are available in AGP and PCI-E then the PCI-E one will always be faster. On PCI-E you don't have the overhead of the bridge chip so it's faster, and you have the better bandwidth so in intense situations such as high resolution gaming you'll come out on top every time.

The main point here is: If you have a system with AGP on it, it doesn't make sense to upgrade just to get PCI-E video right now. The fastest AGP card to ever come out is likely to be the nVidia 6800GT. If you are at a point where that is too slow then by all means it makes sense to make a complete switch. If your happy with your AGP graphics options, wait until you are ready to upgrade the processor or other components before making the PCI-E switch. For more information on AGP and PCI please see the general FSB guide.

Q:What is SLI?
A:SLI or Scalable Link Interface is a technology that lets you take two identical nVidia based graphics cards *that support SLI* and a motherboard *that supports SLI* to achieve a very high level of video performance. SLI works by splitting the rendering of the screen between the two cards- one card renders half, the other card renders the other half. This technique is extremely effective. For instance two 6600GT cards in SLI can do vastly better than a 6800GT or X800 card even though the price is lower for two 6600GT Cards. The downside to this is that SLI is still new and is limited to systems based on AMD 64 / AMD FX Socket 939 processors.

Q:Do I need a special power supply for PCI-E [PCI Express].
A:Yes and no. Although the PCI-E spec calls for a PCI Express power connector, most PCI-E cards don't currently use it. This means that you should only probably worry about this if you are buying bleeding edge PCI Express parts. Card based on the ATI X600, ATI X700, ATI X300, ATI X1300, Nvidia 6600, Nvidia 7600 or Nvidia 7300 series graphic chipsets rarely use the connector. If you are in a situation where you need a PCI Express power connector but the power supply doesn't have one you can always just use a PCI Express Power Adapter that converts a 4-pin molex connector to PCI-E Power.

Conclusion  PCI Express is an exciting advance in the area of computers. Although AGP is now starting to die rapidly, standard PCI is taking/will take longer to die off. Expect to see at least 1 or 2 standard PCI slots along side PCI-E in all motherboards for at least the next 2 years. By that time there will be PCI-E replacements for all common devices such as modems, network cards, raid cards, i/o and more.
DDR2 Short and Sweet There are a few major things you need to know about DDR2 when building a system:
Basic Functionality: DDR2 memory has a different approach to design at the chip level then DDR. The simplest way to understand how it works would be to think that at the low level it had two chips of half the stated memory speed working in tandem together to achieve the full speed stated. So for DDR2 400 it would be something like 2 chips of DDR200 working together to achieve the full 400 speed. Notice that I say "chips" not sticks of memory. All this happens on 1 stick of memory.

The overall effect of this trickery is that manufacturers can scale up the speed of the memory beyond the limits of DDR, with only taking a small hit to the timing of the memory ( how long it takes for the memory to respond back to a request ).

This means that it's possible, and expected to see memory speeds of 533MHz or higher for DDR2. In fact, the current concensus is that if you want to build a system, and have a choice between a motherboard with DDR1 and DDR2 then to see a benefit to DDR2 you need to at least get one speed grade higher than that of the max normal speed of DDR1. ( 400MHz ). This is because the timings ( latency ) of DDR2 are worse than DDR. Essentially in most situation DDR400 ( especially low latency DDR400) is faster than DDR2 400. However, when you get to DDR2 533 the speed boost makes up for the slower timings.

As far as matching FSB to DDR2 speed my recommendations are to skip DDR2 400 and opt for going with the following:

800MHz FSB = DDR2 533MHz ( Ideal ) or DDR2 400MHz ( Matched but Slow. ) 1066MHz FSB = DDR2 667 ( Good ) or DDR2 533MHz ( Matched )

Generally you want to keep the system clock of your memory matching with the root clock of your memory or one step above. So the system clock on a 800MHz FSB P4 is 200 (quad pumped) so that matches DDR2 400 (essentially 200 unimproved) or is good with 1 step up DDR2 533MHz (essentially 266 unimproved). Note however that if you only had a 800MHz FSB processor then DDR2 667 really probably isn't going to help much. Once you pass the 1 step above mark on the memory you have diminishing returns unless you can get to double (DDR2 800MHz).

Compatability: Generally a motherboard is only going to accept DDR1 or DDR2 not both. The slots are physically different and have a different number of pins, however people have been known to force memory into the wrong slots ( And that ends in horrible results! ). Be careful when installing it and make sure the motherboard takes that kind of memory before attempting.

At the time of this writing only motherboards for Pentium4 or Xeon accepted DDR2. AMD Socket 754 and Socket 939 motherboards can't accept DDR2 due to the integrated memory controller in the CPU. AMD is making a line of CPUs that can work with DDR2. They will use new motherboards and have a new socket called M2.

Additional Notes on DDR2: 1) DDR2 is not QDR like I mentioned earlier, the technology is different. 2) DDR2 does give you definate benefits and it is recommended. 3) At the time of this writing ALL motherboards that used DDR2 were Dual Channel Ready. 4) It is not uncommon to hear of problems from people trying to use 3 sticks of DDR2. This stems somewhat from what I mentioned in #3. I recommend either using 1,2 or 4 sticks of DDR2. ( more is ok if you are doing a server but add them in pairs, don't use a odd number of sticks if you can avoid it ).
