how to find remote IP ?

How to find a remote IP

Method 1

To view someone's IP# when they send you hotmail email do this:
1) Click "Options" on the upper right side of the page.
2) On the left side of the page, Click "Mail"
3) Click "Mail Display Settings"
4) Under "Message Headers" select "Full" or "Advanced"
5) Click ok

Method 2
reg a dydns account and install the ip pointer, so each time you ping the host name you regestored

for example:
you regestor the host name myhost.dydns.com, then you keep a little software running on the target host. The little software will keep update your IP to dydns.com server.

so at your pc just start cmd, and ping myhost.dydns.com, it will give you the most updated ip address.

Method 3
neverender, what doesn't work for you? Simply type in nc -vvv -l -p 80 on your box, which will set it to listen in verbose mode on port 80. Then give them a link to your IP address (for example: 111.111.111.11) and tell them to type it in their browser. The browser should resolve the address as well as append port 80 automatically. Just make sure that your friend is not very computer literate.

Method 4
Just download a very simple server such as this one and install it on your comp. Then run it and give your ip to the person you want and tell them to connect to it through a browser. Your server will log their connection and you will get their IP.

Problems faced by a PC

10 reasons why PCs crash U must Know

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.

3 BIOS settings

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.

Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).

4 Hard disk drives

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to

* Start-Programs-Accessories-System Tools-ScanDisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5 Fatal OE exceptions and VXD errors

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6 Viruses

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).

7 Printers

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.

8 Software

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9 Overheating

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU.

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.

10 Power supply problems

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

What’s coming up in 2010

With 2009 in the books, and people starting to see the reality of the app store, I imagine we will see a general decline in the app craze that currently surrounds us. New platforms, and devices, create a sort of gold rush when they are announced. As technologies change quicker and quicker these gold rushes get shorter and shorter. I think it is obvious that as more apps are released and as more developers enter the marketplace, flawless common experiences will be required for apps to be successful. Things like sharing (Twitter, Facebook, Email) are likely to all assimilate as more open source modules for this are introduced. I think an emerging market right now are applications based around accessories. Apple just this month rolled out iPhone accessories for checkout at Apple Stores, along with several others. I imagine we will see things like universal remote adapters, fm transmitters, heath care accessories, scales, and gaming controllers. If these kinds of devices are introduced and gain some popularity it will help to solidify the iPhone in the marketplace, as accessories for any device are really a sort of investment in them. In terms of development changes in 2010, I’m sure we will see SDK 4.0 being released at some point. I can’t speak to new features since they would all essentially be guesses, but I do see apple enhancing one specific type of operation in the next OS revision. A great new feature in OS 3.0 was the introduction of NSOperation and Core Data (Tutorial coming soon I promise!). These tools are Apple’s solution for simplifying the interface to SQLite and NSThreading. I could see apple adding even more abilities to these classes to make background processing even simpler. This could eventually lead to Apple letting the next iPhone run apps in the background like the Palm Pre and some Android distributions.

Gaming


The so called “Golden Age” of arcade games reached its peak in the early ‘80s. During this time, a number of new genres was established, & many new genres were established, &many new innovations in graphics technology were taken place.
Computer gaming didn’t happen until 1982 when two machines were released specifically for gaming the commodore 64 & the ZX spectrum. Initially, the low image processing quality & graphics capabilities of computers limited the types of games released for home computers. These limitations gave rise to text based adventure games. Games such as adventure & Zork established this genre for consoles & P.C.s.
In 1980, a game called Mystery House was published for the Apple-II. This game has a distinction of having been called the first graphic adventure for home computers.
In 1983, SuperSet Software created a text-based computer game called Snipes. This game, played over a network, was designed to test a particular network. And that led to an invention that brought about a big change in the network capabilities in the machine; today Snipes is officially credited as being the original inspiration for Novell Netware.

Internet gaming took off only after first person shooters came into vogue. Games such as Quake could be played over the internet (or any other network) & this increased the popularity of these games as well as other online multiplayer games. Multiplayer capability is now the norm in all FPS & RTS games. Online gaming also includes a genre called simply ’Internet Games ’.
Action Games
As the name suggests, action games have everything to do with fighting, guns, killing bad guys & saving the world. Action also happens to be the most well-known of all genres and the most controversial at the same time. While gamers & developers go gaga over the latest action games, they also come in for a lot of flak from the media for promoting violence.
The action genre has many sub-genres. A few of them are:
a) FPS: Probably the most famous of all genres. FPS stands for First Person Shooter. It places you in the boots of the main character of the game. And only lets you see the game from his point of view. This gives you the feeling of actually being in the game. The FPS genre can be further sub-divided into the following:
1. Stealth: These games are based on the ability to sneak around without being seen by opponents. They are different from traditional FPSes because they place more emphasis on sneaking around rather than on an all-guns-blazing approach.
2. Old School: These feature the run-and-gun type of game play. Action in such games is fast paced, with tons of enemies.
3. Tactical: These games place emphasis on tactics, strategy & teamwork. In many ways, these are the exact opposite of the run-and-gun type of games.
4. Military/War: These are military games, based on the art of war. Examples are- The Medal Of Honour series and Call of Duty. As the player, you are placed in various war missions, which may not enable you to single-handedly save the world, but are nonetheless important in the ultimate outcome of the war.
5. Survival Horror: These is a relatively new sub-genre in FPS gaming. Here, the player is placed in a scary situation. Usually involving ghosts or monsters; the sole objective of the game is survival. Naturally, the basic game play consists of running and gunning, but puzzle-solving elements are also usually built into the game.
b) TPS: TPS stands for Third-Person shooter. Games in this category are similar to FPSes in most aspects, except that instead of giving you a first person view, it places you ‘outside’ the body of your character.
c) Platform: This genre consists of games where the player has to move around on, or jump to and from, a number of platforms. At the same time, one also has to fight enemies and collect objects to successfully complete the game.
Strategy
Strategy games place the spotlight on the player’s thinking & decision-making abilities. That’s why some people call strategy games “the thinking man’s game”.
The strategy genre can be further sub-divided into:
a) Puzzle: Puzzle games involve solving puzzles, which could involve logic, pattern recognition, and strategy. These games are extremely popular because of their simplicity and ease of use. Tetris, Minesweeper and Solitaire are examples of puzzle games.
b) RPG: RPG stands for Role-Playing Game. They generally involve long, intricate plots with an emphasis on character development. As the game progresses, the characters gain various abilities & can achieve feats. The gamer has to choose which feats to acquire so as to complete the game.
c) Real-time Strategy Games: As the name implies, the action in such games takes place in real-time—that is, the state of the game is constantly changing. Hence the player has to always be on his toes and keep modifying his strategy to match changing environments. These are known as RTS games In short, and have become extremely popular today.
d) Board Games: Board games are simply digitized versions of classic board games. Games such as backgammon, chess, and checkers have all been made for computers, as you’re probably aware.
e) Sims: ‘Sim’ is short for ‘simulator’. Sims are simulator games that usually put their focus on strategy.
Adventure
Adventure games are characterized by exploration, puzzle solving character interaction & emphasis on narrative. Games belonging in this genre have fantasy, horror, mystery as well as comic elements in them.
The standard adventure games died out when 2D was replaced by 3D. Today, most adventure games are a mix of a number of genres. For examples, Prince Of Persia: the sands of time is a mix of action & adventure elements, with a third person view.
There are exceptions, though. Games such as Myst continued to be popular even in the 3D era. But the fact remains that adventure games are no longer major players in the gaming industry.
Simulators
Simulators are games that focus on accurately recreating a real life situation in as possible. Realism is the most important factor here, with every attempt made to make the game as true to real life as the software and hardware can allow. The craze for realism has been taken to incredible levels today, with some games to realistic that they can be used to train professionals in their respective fields! This genre is sub divided into:
a) Flight Simulators: Flight simulators, obviously, try and re-create aircraft and their controls. They attempt to copy the controls found on an aircraft-commercial or otherwise-as well as the difficulty in actually flying one. Microsoft Flight Simulator is an excellent example.
b) Racing Simulators: Racing simulators are based on accurately re-creating racing environments. This category includes not only car races, but virtually any kind of race, take boating, for instance. The most popular games in the sub-genre are naturally of the car racing variety, with games based on F1 and rallying among the most popular.
c) Combat Simulators: These take the realistic elements of simulators & adapt them into a combat style game. Here, defeating your opponent in the ultimate objective, but it can only be done if you have a good knowledge of how to operate the machinery the gamer is given, in realistic condition.
d) Sports Simulators: The objective here is very simple- to recreate the playing condition of a particular sport in the most realistic way. Of course, that’s easier than done! Sports simulators tend to be the most difficult to make, with a lot of effort going in to make them realistic, without making them confusing or unwieldy for the gamer.
MMOG
MMOG stands for massively multiplayer online game. Online gaming has really taken of at present, with broadband internet becoming a reality for a large number of people. Not only do we have the (usually online) games where a few players take on each other, we now have MMOGs, where thousands player can be online simultaneously in a simulated environment.
The most popular MMOG are::
a) MMORPGs: MMORPGs (Massively Multiplayer Online Role Playing Games) are the most popular types of MMOGs. They follow the client server model, where the gamers running the client’s software is represented in the online world they inhabit via an avatar. The online world is hosted on a server that is usually owned and by the game’s publishers. The most popular MMORPGs are Ever Quest-II, World of War Craft, The Matrix Online, and Star War Galaxies. India, too, has been bitten by the MMORPG bug with Ragnarok being popular among Indian gamers.
b) MMOFPS: this is a massively multiplayer version of the traditional FPS. Although the idea of having thousands of gamers online in an FPS game sounds enticing, it has proven to be difficult to it into practice. One major problem has been the fact that, by the very nature, the games require fast reaction times; thus, hosting a server in a centralized location means increasing lag times for gamers around the world, there by rendering the game unplayable.
c) MMORTS: The third & probably least popular category of MMOGs is the MMORTS, where RTS stands for Real Time Strategy. Once again, it incorporates the offline elements of a regular RTS & adapts them for online play with thousands of gamers.

how to be an animator ?

There are a number of different career paths for animators. We often think of animators as the talented artists who create the cartoons we love, either for film or movies. Animators continue to work in these areas, but increasingly, many are employed creating animated graphics for a variety of projects.

This can include websites, online advertisements and video games. Animators can find full-time employment with movie or television production companies, with advertisers, web design firms, video game companies or with animation firms. Free lance work is another option for animators, particularly those specializing in web animation. Most entry-level positions will require an animator to have a bachelors degree in a related field such as fine arts or media. There are a number of animation schools that offer course work specifically in computer animation and associated technologies. In addition, a strong portfolio of work, which a training program can help you to develop, is an essential part of landing a job in computer animation and becoming an animator.
