  1. Sounds like a job for hardware encoding, but I presume that you are using a laptop so sticking a capture card is not so easy. There are a few USB devices which can capture composite/audio, or you could use a network based camera. Even MiniDV camera (connected via Firewire) will do pretty good compression for you. At MiniDV you're looking at around 10G per hour. Disk space is cheap now days, why not just grab and (re-)encode later? Of course the extreme hardware solution is to capture everything with a digi-camcorder to a *huge* memory stick. Mungewell.
  2. Unfortunately there's money to be made in the standards industry..... the best thing to hope for is that you can find a copy laying around on the net. Sometimes a standard will be adopted by another country/organisation under a different number, and sometimes you can get an almost exactly standard at a different price. Personally I find it rediculous that an organisation who is supposed to be promoting standards feels that it has to charge for electronic copies (same a paper in this example), if they want people to use standards then open them up! Munge.
  3. Depends on what you want to do.... most applications mentioned use a camera to 'see' and decode the barcode. CCD devices are not as accurate as line/laser scanners (1D only) and don't cope well with smaller barcodes. They also require much processing on the host system. A RS232/USB/PS2 connected 'hardware' scanner can prevent loading the host down. Cheers, Mungewell.
  4. Nah, that's old hat....... mobile barcodes is where it is at!! There are tonnes of downloads for 2D barcode scanners/decoders, which when installled on your cell phone can direct your mobile browser to the URL encoded in the barcode. Japan has been doing this for years and it appears that this is the year that it is coming to North America. The main formats are 'QR Codes' and 'DataMatrix', but there are a few propriatory codes (Microsoft Tag for example). The best site I have found so far is: which provides 3rd party download links for a large number of scanner applications. There are also a lot of 'barcode' links here: Have fun, Mungewell. PS> Yes, I'm a barcode geek!
  5. Does the webmail server provide other methods of connection, IMAP for example? If so you could connect with a desktop client via IMAP and copy all the emails to a local folder. Cheers, Mungewell.
  6. For VGA to Composite/RGB you can build cables that merge V-Sync and H-Sync together well enough to sync a TV, but they're pretty nasty and need control of the display refresh rate etc. You can do this relatively easily with an X modeline, or even by hacking the console settings (can't remember the name of the app right now.... it was 10 years ago that I was playing with this). For your iBook you could try another way, firewire. A cheap/broken mini-DV camcorder should be able to render streamed DV out of a composite port and into a TV. Mungewell
  7. What are you trying to achieve? I'm guessing access to machine(s) on you LAN from the outside world. Is this just access for yourself, or are you attempting to run a service for (random) other people? You could have a machine inside you LAN make an outgoing connection to a VPN service. This will allow you to connect into your LAN from the outside/internet (via the VPN). Cheers, Mungewell
  8. There's also 'webcamstudio' if you are a Linux user....
  9. It should just provide the appropriate devices (/dev/ttyS0, etc).... unless it's a 'funny' card. What does 'lspci --vv' say about the card? Mungewell.
  10. Mostly USB serial adapters will 'just work', they will appear on '/dev/ttyUSBS0' or '/dev/ttyACM0'. I have tried multiple ones (both stand alone and within USB docking stations). On thing is that the timing of a USB device is not guarenteed, so if you application is really sensitive to timing you may have problems with USB Serial. Sometime the 'drive' capability of these USB serial adapters is weak, so you might have problems if the circuitry is passively powered from the RS232 signals. Cheers, Mungewell.
  11. Check the memory, it may be that you have some 'RAM gone bad' in there. This can be done without messing with your install. There is a memcheck on all of the Ubuntu CDs or on 'UBCD' ( The next step is to re-install/re-image the drive.... Mungewell.
  12. PaulDotCom had a segment about accessing SIM cards (which are a smart card of sorts), maybe this info will get you a little further: Mungewell.
  13. Interesting.... and a bit worrying. I keep telling my wife that you _HAVE_ use the 'https://' page _AND_ check the SSL cert before logging into our E-bank. Just for amusement value '' automatically redirects you to '', opening them up to this attack! Mungewell.
  14. I would do a 'lsmod' whilst the BT device is working, this should give you an idea of which modules are being used to control the device. You can then (as root/sudo) use 'rmmod' and 'modprobe' to remove and reinstall the relevant modules. There may be several modules associated with providing functionality, but one of them would presumably handle loading the firmware into the device. Cheers, Mungewell.
  15. I printed this book out at my school library a few days ago. It is very easy to read and interpret. Props to the authors. There is now a HPR (podcast) series based on this book: Mungewell.
  16. I believe that your problem is likely to be that you have a V4L2 webcam and Flash 9 does not natively support it. There is a project to get around this: I know that Stickam works with Linux as the TLLTS guys have been using it, although I have not tried it myself. Another project you might enjoy is: Have fun, Mungewell.
  17. I previously (like last century!!) played with 'vgetty' (Linux Voicemail client). If it has voice capability, then it is normally really cheesy quality. There will be an 'AT' command to enable it and one to enable pickup after x rings. The following page may also help (remembering that soft modems are the Devil's spawn!): Mungewell.
  18. I'm not convinced that you mean to 'cluster', what application(s) are you hoping to improve the processing power of? Clustered system usually have a specific task in mind, such as agressive computation, etc. Linux, by default, give you the power the run remote applications (where application is running on machine and displaying on another). A more 'co-ordinated' version of this is the LTSP (Linux Terminal Server Project). LTSP can also be configured to run some applications which would require a lot of X bandwidth locally. If you simple want to play with Linux PMI just because you can.... then good luck, let us know how it pans outl! Cheers, Mungewell.
  19. I take the view that you learn the most by trying to solve a specific problem, I too am just getting started with python and have jumped into 'the deep end' with pyGTK, V4L2 and threading.... I have a number of suggestions of things the 'need' fixing with other projects if you want them. There are some helpful books/tutorials out there: Mungewell.
  20. If your ISP is blocking ports, you might find that you can move the services to non-standard ports. Mungewell.
  21. There are quite a few videos here: Enjoy, Mungewell.
  22. Can recommend from personal experience, but there are a whole whack of projects on Freshmeat: These mainly look to be LAMP (Linux-Apache-MySQL-PHP based) but should happily run on a Windows host if coded correctly. Mungewell.
  23. Well if the screen is intact you can probably get close to $25 for it on Ebay.
  24. Thinkwiki's page for this model: Contains a link the hardware maintainance manual which might give you some leads, BIOS updates can be found here: Does it boot from floppy if you use a DOS/Linux boot floppy? Does this machine have onboard RAM (so don't) and is RAM fitted/OK? Mungewell.
  25. so he also gave a similar talk at 24c3: Munge.
