| So much information is on the web, its mind boggling. Thankfully we have search Engines to sift through them and catagorize them for us. Unfortunatly, there is still so Much info that even with these search engines, its often a painstakingly slow process (something comparable to death for a hacker) to find exactly what you're looking for. Lets get right into it. I use google.Com as my primary search engine because it presently tops the charts as far as The sites that it indexes which means more pertinent info per search. 1. Page translation. Just because someone speaks another language doesn't mean they don't have anything useful to say. I use translation tools like the ones found at http://world.altavista.com To translate a few key words I am searching for. Be specific and creative because these tools arent the most accurate things on the planet. 2. Directories. These days everything is about $$$. We have to deal/w SEO (search engine optimization) which seems like a good idea on paper until you do a search for toys and get 5 pornsites in the first 10 results. Using a sites directory will eliminate that. You can narrow your search down easily by looking for the info in specific catagories. (PS google DOES have directories, they're at: directory.google.Com) 3. Here are some tips that google refers to as "advanced" A. "xxxx" / will look for the exact phrase. (google isnt case sensitive) B. -x / will search for something excluding a certain term C. Filetype:xxx / searches for a particular file extention (exe, mp3, etc) D. -filetype:xxx / excludes a particular file extention E. Allinurl:x / term in the URL F. Allintext:x / terms in the text of the page G. Allintitle:x / terms in the HTML title of that page H. Allinanchor:x / terms in the links 4. OR Self explanatory, one or the other... (I.e.: binder OR joiner) 5. ~X Synonyms/similar terms (in case you can't think of any yourself) 6. Numbers in a range. Lets say you're looking for an mp3 player but only want to spend up to $90. Why swim through all the others? MP3 player $0..$90 The 2 periods will set a numeric range to search between. This also works with dates, weights, etc 7. + Ever type in a search and see something like this: "The following words are very common and were not included in your search:" Well, what if those common words are important in your search? You can force google to search through even the common terms by putting a + in front of the denied word. 8. Preferences It amazes me when I use other peoples PCs that they don't have their google search preferences saved. When you use google as much as I do, who can afford to not have preferences? They're located on the right of the search box, and have several options, though I only find 2 applicable for myself... A. Open results in new browser B. Display 10-100 results per page. (I currently use 50 per page, but that's a resolution preference, and 5X's the default) 9. * Wildcard searches. Great when applied to a previously mentioned method. If you only know the name of a prog, or are looking for ALL of a particular file (I.e.. You're DLing tunes) something like *.mp3 would list every mp3. 10. Ever see this? "In order to show you the most relevant results, we have omitted some entries very similar to the X already displayed. If you like, you can repeat the search with the omitted results included." The answer is YES. Yes yes yes. Did I mention yes? I meant to. 11. Search EVERYWHERE Use the engine to its fullest. If you don't find your answer in the web section, try the group section. Hell, try a whole different search engine. Don't limit yourself, because sometimes engines seem to intentionally leave results out. Ex. Use google, yahoo, and altavista. Search the same terms... Pretty close, right? Now search for Disney death. Funny, altavista has plenty of Disney, but no death...hmmm. If you've read this far into this tutorial without saying, "Great, a guy that copied a few google help pages and thinks its useful info" then I will show you WHY (besides accuracy, speed, and consistancy finding info on ANYTHING) its nice to know how a search engine works. You combine it/w your knowledge of other protocol. Example: Want free music? Free games? Free software? Free movies? God bless FTP! Try this search: intitle:"Index of music" "rolling stones" mp3 Substitute rolling stones/w your favorite band. No? Try the song name, or another file format. Play with it. Assuming SOMEONE made an FTP and uploaded it, you'll find it. For example....I wanted to find some Sepultura. If you never heard them before, they're a Brazilian heavy metal band that kicks ass. I started with this: intitle:"Index of music" "Sepultura" mp3 <-- nothing intitle:"Index of música" "Sepultura" mp3 <-- nothing intitle:"Index of musica" "Sepultura" mp3 <-- not good enough intitle:"Index of music" "Sepultura" * <-- found great stuff, but not enough Sepultura At this point it occurs to me that I may be missing something, so I try: intitle:"index of *" "sepultura" mp3 <-- BANG! (and thats without searching for spelling errors) Also try inurl:ftp I find that * works better for me than trying to guess other peoples mis-spellings. The same method applies for ebooks, games, movies, SW, anything that may be on an FTP site. I hope you enjoyed this tutorial, and I saw that recently a book and an article was written on the very same topic. I havn't read them as of yet, but check em out, and get back to me if you feel I missed something important and should include anything else. Intitle:"index of" "google hacks" ebook Ps. I've said it before, I'll say it again... BE CREATIVE. You'll be surprised what you can find. | ||

Data Capacity of CDs [Tutorial]
| Data Capacity of CDs [Tutorial] Abstract You can fit on a S/VCD without overburning: - approx. 735 MB of MPEG data onto a 74min/650MB disc - approx. 795 MB of MPEG data onto an 80min/700MB disc You can fit on a CD-ROM without overburning: - approx. 650 MB of data onto a 74min/650MB disc - approx. 703 MB of data onto an 80min/700MB disc ---------------------------------------------------------------- Introduction Let us ignore for now the terms of megabyte for CD capacity and try to understand how the data is stored on a CD. As well all know, the data is stored digitally as binary data. This means, however the actual information is actually kept on the disc, this information is in the form of "1"S and "0"S. Physically, the information on a CD is as pits on a thin sheet of metal (aluminium). An a CD-R disc, the data is physically on an organic dye layer which simulates the metal layer on a real pressed CD. ---------------------------------------------------------------- How is the information structured Now, on the CD, the information isn't just organised from beginning to end willy-nilly. Otherwise, it would be really hard to find a useful piece of information on the CD. Rather, the information is organised in sectors. Consider a sector as like a page in a book. Just like you are able to quickly find something in a book if you know the page number, you can quickly find something on a CD if you know the sector number. Now, remember that the CD was original made to hold audio data. It was decided, that the CD would would 75 sectors per second of audio. Although I cannot guess where this number comes from, it is quite appropriate for the audio CD. It means that you can "seek" an audio CD accurately to 1/75th of a second -- which is more than enough for consumer purposes. Now, with this in mind, we can work out the total data capacity of user data for 1 sector. ---------------------------------------------------------------- The total data capacity of user data of 1 sector on a CD CD audio uses uncompressed PCM stereo audio, 16-bit resolution sampled at 44.1 kHz. Thus 1 second of audio contains: 16 bits/channel * 2 channels * 44100 samples/second * 1 second = 1411200 bits = 176400 bytes Since there are 75 sectors per second 1 sector = 176400 bytes / 75 = 2352 bytes One sector on a CD contains 2352 bytes max. ---------------------------------------------------------------- The concept of different MODES and FORMS of burning Now, audio CD was well and good, but the medium would become much more useful if you could store other data on the disc as well. This became to be know as CD-ROM of course. Now, the audio-CD uses the ENTIRE sector for audio data. However, for CD-ROMs this caused a problem. Simply, CDs and the CD reading mechanisms were not 100% faultless. That is, errors (indeed frequent errors) could be made during the reading. For audio CDs, this does not matter as much as you could simply interpolate from the adjacent audio samples. This will obviously NOT DO for data CDs. A single bit error could lead to a program being unexecutable or ruin an achive file. Thus, for CD-ROMs, part of each sector is devoted to error correction codes and error detection codes. The CD-R FAQ has the details, but in effect, only 2048 bytes out of a total of 2352 bytes in each sector is available for user data on a data CD. This burning mode is either MODE1 or MODE2 Form1. ---------------------------------------------------------------- MODE2 Form2 sectors of VCDs and SVCDs Now, for VCDs and SVCDs, the video tracks do not necessarily require the robust error correction as normal data on a CD-ROM. However, there is still some overhead per sector that is used for something other than video data (e.G., sync headers). S/VCDs video tracks are burnt in what is called MODE2 Form2 sectors. In this mode, only 2324 bytes out of a total of 2352 bytes in each sector is available for user data. This is MUCH MORE than for CD-ROMs, but still less per sector than audio CD. ---------------------------------------------------------------- The disc capacities of CD-ROMs, audio-CDs and VCDs Now, obviously what ultimately determines the capacity of a disc is the total number of sectors it contains. This is similar to the total number of pages in a blank exercise book (if you recall the book analogy). The secondary determinant is the burning mode of the disc. For audio CDs, it is as if you could fill each page from top to bottom with audio data as the entire sector is used for audio data. For CD-ROMs, it is as if you need to first rule a margin and then leave the bottom part of each page for footnotes (headers + ECC + EDC). The amount of text you can actually write per page is then less due to these other constraints. For S/VCDs, we still need to rule a margin on the page, but we don't have to worry about the footnotes (headers). We can fit MORE text than a CD-ROM, but less than an audio-CD. Now remember, 1 second on a CD = 75 sectors. Thus: - 74 min CD = 333,000 sectors - 80 min CD = 360,000 sectors Data capacity in Mb for an audio-CD 74 min = 333,000 sectors * 2352 bytes / sector = 783216000 bytes = 746.9 Mb 80 min = 360,000 sectors * 2352 bytes / sector = 846720000 bytes = 807.5 Mb Data capacity in Mb for a CD-ROM 74 min = 333,000 sectors * 2048 bytes / sector = 681984000 bytes = 650.4 Mb 80 min = 360,000 sectors * 2048 bytes / sector = 737280000 bytes = 703.1 Mb Data capacity in Mb for a S/VCD 74 min = 333,000 sectors * 2324 bytes / sector = 773892000 bytes = 738.0 Mb 80 min = 360,000 sectors * 2324 bytes / sector = 836640000 bytes = 797.9 Mb ---------------------------------------------------------------- Conclusions As you can see, the often quoted capacities of 650MB and 700MB refer to CD-ROM capacities. Due to the fact that S/VCDs use a different burning mode where MORE of each sector is available as user data, the relatively capacities are HIGHER. Now, since S/VCDs are not composed of PURELY video tracks and have some unavoidable overheads, the actually total capacity left for video tracks is a few Mb less for each disc (about 735 Mb for 74min discs and 795 Mb for 80min discs). This is where the often quoted capacities of 740MB and 800MB come from. They are quite accurate. All these capacities are available BEFORE overburning. Overburning is where you burn MORE sectors than the disc is rated for. If you overburn, you can typically achieve about 1-2 minutes of additional capacity (depending on your drive and media). ---------------------------------------------------------------- | ||

Creating Universal Ghost
| If you want to use Norton Ghost 2003 to create an image of a PC's primary partition you will find it has 2 serious limitations: 1- The USB support driver they use (from Iomega) can only be installed in USB1 or USB2 mode (not both), and it is not universal - it didn't recognize my external USB IBM mobile HD . 2- You can't create a Ghost bootable CD - only a floppy. How can you clone a newly bought laptop, most of which don't have a floppy anymore? Here's How to: 1- create a Ghost floppy with USB support (1 or 2 - it won't matter later) 2- download 2 files kxlrw40an.exe and mhairu.zip CODE CODE From the first file (Panasonic driver for a USB CDRW) you will need the file usbaspi.sys found under "F2H" sub directory after extraction of the downloaded archive. From the second archive you need di1000dd.sys 3- Copy these 2 files to the USB folder on the Ghost floppy, and delete any other files in that folder. Also delete the file guest.exe from the floppy's root. 4- And finaly: Edit the AUTOEXEC.BAT file - delete the line: guest.exe And edit CONFIG.SYS - delete all entries and enter: Device=usb\USBASPI.SYS /v /e /O /U Device=usb\Di1000dd.SYS LASTDRIVE = Z That's it. You can now boot with this floppy and have full USB support so you can create the image on an external USB drive. If you want to create a bootable CD you can use Nero: Choose to create a "CD-ROM (boot)" from the wizard, under Boot tab leave the default "bootable logical drive: as A:\ . Insert your Ghost floppy to the drive, drag all the files from the floppy to "New compilation" and burn. You now have a bootable Ghost CD that even Symantec doesn't have.. PS if you need Norton Ghost 2003 get the full retail here: CODE | ||

Converting Movies To Psp Format
| Converting Movies To Psp Format. Hey again, this is a real quick guide for anyone interested to get a movie onto there PSP without all the fluff I have seen elsewhere. I just watched Africa the Serengeti on my PSP and heres is the lowdown. Movie - approx 40 minutes - dvd Saved to hard drive - 2.6GIG - using DVD Decryptor (free program) try google Transferred to avi format - 377MB- using Super DVD Ripper (9 FREE trial uses) then you must buy Transferred to MP4 - 37MB - using the (basically free) Image convertor 2 Average movie breakdown - using above as a guide only. So I'm guessing the average movie may be 4.5gig for example Saved to 800MB CONVERTED TO 70-80MB Ok use DVD decryptor to save the movie to your hard drive e.G.. C:\Africa (it will save it for you as described) When completed find the folder c:\Africa on your computer and find the vob file in that folder - generally the largest one and right click and play it with your dvd program to see what part it is. If its the correct movie part you now know that's the one you need. Once you have located the vob file you want to transfer open DVD Ripper and go to wizard icon. There you will see an icon of VOB to AVI button. Click it and then it will ask to locate the file. Locate the file and click it. It will SCAN THE FILE(just wait till that finishes) a parameter box opens next and just click the arrow. It then askes to choose output file, click the file icon and locate the correct fob file. It then askes for file compression - choose Microsoft windows media and then click ok Then press the start button. It will now convert the vob into avi format. (there are also other opions I.e.;dvd to avi etc) I have only used the vob to avi for this test. After DVD ripper has transferred the file it will save it to the same folder as the original move was in e.G.: c:\Africa\viteots. Open the file and you will now see an AVI icon containing the movie. Make sure you PSP is on and in usb mode then Open Image convertor 2 and press on movie / add to list. For this example I click on C:drive the found the folder Africa and opened it and there was my converted AVI file. Click the file press ok and it will be transferred to your PSP for viewing pleasure. *****Note**** I only converted one VOB file as thatS all there was for this particular movie. If you have more then one vob file you may need to try the dvd to avi when you rip. This is just a guide I worked out to compress dvd into the smallest possible file so you can get value out of a 512 card. Image Converter 2.1 JAP translated to ENG. | ||

Cannot use My Password
| Because of the security features built into Windows XP, it is virtually impossible to get back into the system without the password. You have several options to try and get around this problem. If you have access to another user account with administrator rights, you can use that account to change the password Of the account that is locked out. You can also use the default Administrator account that is built into Windows XP. First you need to boot the system into Safe Mode. 1.Restart your system. 2.When you see the blue Dell globe or screen, press the ( F8 ) key about 3 times a second. 3.You should get the Windows startup menu. Use the (Up or Down) arrow keys to highlight (SafeMode) 4.Press (Enter) on (Safe Mode), then press (Enter) on (Windows XP). 5.The system should boot to Safe Mode. Once you are at the Account Log on Screen, click on the icon For the user account with administrator rights, or click on the icon For the administrators account. Note: For Home the Administrator account isn't normally shown & in Safe Mode you have to press Ctrl+Alt+Delete keys twice to show. For PRO you can do this in normal mode When the system has booted to the desktop, use the following steps to change the accounts password. 1.Click Start, Control Panel, Administrative Tools. 2.Click Computer Management. 3.Double click Local Users and Groups, double click the folder Users. 4.Right click on the account name that is locked out, and click on Set Password. 5.You may get a warning message about changing the password, simply click proceed. 6.Leave the New Password box blank, also leave the Confirm Password box blank. 7.Click OK, and OK again. 8.Then close all Windows, reboot the system and try to log in. There are also applications that can recover the password for you. The following companies provide these applications at a cost. IOpus® Password Recovery XP here. LostPassword.Com, here. Asterisk Password Recovery XP v1.89 here. Windows XP / 2000 / NT Key here. If the above information does not help in recovering the password, the only option left is to Format the hard drive then reinstall Windows and the system software. | ||
