This machine is designed for a more subtle version of HD cinema (Compared to earlier attempts!) The luma (Main bulk of data) is stored using analog methods on FM carriers. There is no color burst or color subcarrier, so the resulting image is 'cleaner'. The analog information is digitally time- aligned, ensuring it lines up perfect with previous and future fields. The chroma channel uses MPEG style compression. On playback, the chroma and luma channels are carefully digitally time-aligned to eliminate problems with chroma jittering in relation to luma. The data rate of the chroma alone is about 3 Mbps. Seperate heads are apparently used for luma, and chroma/audio. There is spectrum left in the chroma and audio channels for a substantial amount of metadata. The format has not been popular at this time.

Now I'm not a Microsoft basher but I wonder why it has taken ten years of people hooking up Windows machines to the Internet for XP SP2 to actually have a safe configuration as default? I'm a geek and know how networking works - I pity people who aren't as in to it as me when they attached to always-on connections.

I have a Neo35 car MP3 disk system - thirty gigs of MP3s in the boot and a wired remote on the dash - very nice - all my CDs in the car! Anyhow - about a year ago (and a few days outside the warranty period!) it developed an annoying fault whereby the back key would randomly press itself (sending the song back to the start). Once this started it was like it until you reset and sometimes you had a few minutes grace, sometimes half an hour. I was is a logic issue as it does it whether the wired remote is attached or even if the disk is in the USB caddy you use to download into it on the PC. Ho hum - then, along comes the Open Neo Project where the company has opened the firmware to the wider programming community and they've produced a version that allows you to re-map the keys - nuff said! I'm back in-car-MP3-nirvana!

I wish I'd waited a few days between upgrading the machines on my network at home! Despite Joel's reassurances AND the promise of a working Bluetooth stack I took the cautious route and upgraded the media machine first - all seemed well - I then (after only an hour of thinking about it!) upgraded the main family machine - here are a few observations:
1. DivX codec is affected by the new Data Execution Prevention schema - bummer! You can disable this by changing the following parameter in boot.ini
/NoExecute=xxxxx with /Execute
2. Pop-up blocker in IE is no better (and I'm getting the feeling it's worse) than the Google toolbar.
3. The firewall's config is so simplistic as to be unusable.
4. Even though I have a current version of Norton AntiVirus (updated an hour before the SP2 upgrade) it can't verify if it is working.
So, I've disabled all four of these features on all machines - I do have an industrial firewall/proxy between my LAN and the Internet and so I still feel as safe as I ever did - if you have a lone machine attached to the web maybe leaving the firewall on would be preferable.

Back in December I blogged on about using a G4 kyboard with XP - well although I was quite pleased it was never just right - position of quote marks in relation to the pound and dollar symbols. Anyhow - I came across this brilliant Microsoft utility that allows you to build new keyboards - none of that messing around with scan-code mapping (although that is useful to put a "print screen" key on an used key on the Apple keyboard). Anyow - here is a layout for a UK G5 keyboard (pained as I am to admit, it is the best keyboard around!) - I have no dead-keys defined as I don't like them - get it here - extract and run the .msi file.
