    Okay, that makes no sense.

    It sounds like you are talking about auto-stretch scaling. That the monitor is at 800x600, the game is 320x240 and is automatically up-scaled to 800x600 by the OS. It isn't possible for a monitor to display "multiple resolutions" at once by definition of what a 'resolution' is. Auto-scale also presents aliasing problems without a decent anti-aliasing algorithm.

    Yeah, unless you saw it in action, it's hard to imagine. It is exactly like the parent post describes, and you can have two (and only two) different resolutions displayed at once. You could be playing a game at 320x240 and drag your desktop down over half the screen, at a higher resolution. It was a horizontal division between the two (you couldn't have, say, one smaller window of one resolution on a desktop of a larger resolution) and (remember, we're using CRT based monitors here, and hardware that has an intimate knowledge of how the scanlines are driven in the limited range of CRT displays the Amiga supported) and the top half of the screen would be drawn at a different resolution to the bottom half of the screen, or wherever the division was dragged down to. It was pretty magical stuff...

    The keyboard garage. The 1985 Amiga 1000 keyboard tucked neatly under the computer where it didn't take up desk space, was hidden from children's fingers and was spill-proof.

    How about tucking the slim and very flat keyboard on top of the foot of an iMac. Or, use a wireless keyboard where you can move it out of the way anywhere you like.

    Tight integration of hardware with O.S. O.k. this works against everything we've been taught about abstracting everything but since the PC world has boiled down to little more than an O.S. monopoly, a hardware monopoly and a graphics card monopoly, why not eliminate some of the levels of abstraction that will never be used and make my 2Ghz PC perform every day tasks at least as well as my 7Mhz Amiga did?

    I like to have modern abstractions, like a HAL, so my OS doesn't need to be written in hand-tuned assembly specifically for the hardware I'm running it on. Even in the relatively closed ecosystem that runs Mac OS X there's far more variety in hardware that the one OS image will run on than there was in Amiga land. What kinds of tasks could a 7MHz Amiga do that would cause your 2GHz PC to struggle? I can't think of anything off the top of my head. Even back in the mid 90's when Amiga fans were extolling the virtues of the custom hardware in the Amiga, on the PC side of things we were able to achieve much of the same by brute force. Copper Bars - done by palette switching very quickly in the horizontal retrace interval. Sprites - once again, done using brute force on the CPU, or with graphics card hardware. Even compiling the sprite to assembly to speed up it's operations. Using the blitter to move/copy memory quickly. Done using, once again, brute force or DMA access and done as quickly.

    I'm all for nostalgia, but don't let it cloud your vision with just how far computers have done today.

  4. LEDs do generate a fair amount of heat on Midwest Seeing Red Over 'Green' Traffic Lights · · Score: 1

    In an LED light cluster, there are heatsinks on the back that bleed off the excess heat. If you open up one of these new-fangled LED traffic lights, I guarantee that there will be a heatsink in there. All they need to do is design them so that the heatsink can, using heat pipes or something like that, channel the heat out the front of the traffic light - maybe have the heatsink attached to the shield above the light that is trapping the snow...

    Adobe Acrobat specifically has a Redaction feature that was included for this exact reason.

    If you use it properly, you hilight the sections of text or images that you want to be redacted and pick the colour you want the covering rectangle to be. Once you apply the redactions, Acrobat removes the text from the page, removes any indexed text that refers to the redacted text (eg in a TOC link) and also offers to remove just about all the metadata in the PDF as well. Once redacted, the text is simply not in the PDF any more, it's gone. You can delete the rectangle but the text is not underneath it. You can't search for the text and you can't find it hidden in the metadata in the PDF either. It is completely gone.

    This is an incredibly easy way to achieve what you want to do as you just hilight the text and click Redact. No drawing fiddly rectangles or anything like that. You can delete the rectangle object but there's nothing underneath it, it's simply there for visual appeal.

You can have additional keychains with various levels of security over and above the login one - have them lock after a period of inactivity, have them lock when the screensaver is activated, have a different password to access them from your login keychain etc. The keychain can also be synchronised between different computers that you use, so if you create a login to a website on one, you can access the password you used on another one. As this works really well, I now use different randomly generated strong passwords for every site I need a login for - eg Bapdageshem9, negTuthsuc5 or EyHepGoyft8 ( apg -n 1 -m 10 -x 12 -M NCL -d )

No moving parts, not even a fan. 100% solid state.

    Try Texas Instruments' BeagleBoard - it's an OMAP3 (ARM Cortex A8) at 600MHz, has an OpenGL ES capable graphics card (10M polys/sec, HD video) and can run off USB power or DC5V. DVI-D + S-Video for the display and they can boot off either the internal flash or an SD card (cheap storage!)

    They are $150 and run Linux in various flavours or even the free home use version of QNX if you need hard realtime capabilities.

    The design is quite open - check out the System Reference Manual

    Running off either 5VDC or USB power, it typically uses 350mA, so it's using just 1.75W of power.

    Now, it doesn't have Ethernet built in, but there is an expansion board available that adds this, or there's a USB hub you can get for it with an Ethernet port and you're up and running. Cutting your home server's power usage by a factor of 50 will have a pretty positive ROI.

    Installation is pretty easy, you can download a pre-built image, copy it to the SD card, plug the SD card into the beagleboard and up you boot.
