Re:Does executing halt instr still save power?

Yes, once the processor hits the HALT instruction, the gates stop transistioning between the on and off states, where the power is consumed. When these logic gates stop, they just act like capacitors and sit with its charge. When the keyboard, timer, etc., or other interrupt is activated, the processor starts executing instructions until the end of the interrupt routine and executes another HALT at the end.
My laptop consumes 33 watts at full throttle, but consumes about 12 watts throttling the HALT instruction due to other electronics. You can watch how much your laptop consumes by splicing an ammeter and voltmeter from the power supply. Power in watts is voltage multiplied by current.
If you have the wattage, you can express this as kilowatt hours and calculate the cost of running your laptop each month for nonstop use. Its usually 8 cents per kilowatt hour or 2 cents for the industrial rates. Running my laptop while chewing on CSC keys in the background cost me $1.90 a month.
I'm inspired. I'm not expert about Y2K issues, but I'm afraid my refrigerator is not yet compliant. One trip to the liquor store down the street should fix that. Maybe put one of these X10 sensors in there and a perl script to log a pretty graph through a www interface if I need to check the temperature of the vital beverages. It never hurts to be fully prepared for events that only happen once in a 1000 years.
I agree that if a company releases its blueprints for the hardware and source code, there will indeed by cheap knock offs.
I would further say that if their interesting gizmo kept all a secret, it will be a puzzle and a challenge to see what makes it tick. This results in a second generation engineering job, not the cheap clone job of the disclosed product. I'd venture to say that those who hold secrets will face some competition with improved products that are missing the bugs. On the other side of the fence, the manufacturer who disclosed the prints only needs to appeal to the quality buying public and sell their brand.
I used to repair televisions and VCR's (when they really were worth some money.) Schematics were available. When we traced down the problem to make repairs (easy with the information,) we often found the weak spots in design. This information was passed on to the company. Better designs followed later.
There were a few manufacturers that were impossible to reach to get any repair information or parts. Not surprisingly, those manufacturers were quickly forgotten about as their products quickly left the market. Who's going to buy stuff that is unmaintainable over and over again? With the exception of Windows, this is rare.
they don't need my email. I'm not signing unless they don't require it. And I'm not the only one.
Make a bogus, yet legitimate email address that you never intend to read. You can email me there, the message will be received, but will pour the shiny electrons into the bitbucket recyclotron. Use the command "adduser nospam" and you have an instant throwaway account!
Its not even factual and offtopic character assassination at best. I have met three of the above mentioned people and this appears to be a work of fiction by a newbie.
I agree. It seems from many of the posters, there appears to be ignorance of the significance of awards to the community. It doesn't just benefit Miguel, it benefits free software as a whole. Consider it a stamp of approval on the work Miguel has helped with. It is this work that my parents can run Linux and with some awards to dispell the FUD, my employer might be next to benefit from running a better computing environment.
I feel there is a lot of unjustified hecklers lately that are even going far as making personal threats against those who contribute. They appear very disturbed. Maybe its because they are threatened by Linux?
I care. When I have the need to use a strange new hardware device that I don't know much about, I find that the kernel Mr. Torvalds shapes is easy to configure, debug, and fix. Might I mention that the kernel is very flexible and most reliable. So, I'm not surprised when a kernel he hacks creates a great impact on the computing industry. If you don't watch what he does, you might be in the dark.
I agree. Cached pages are a great feature. If someone were attempting to make this a vorbotten practice, I would be most unhappy. If one does not wish the public to view information, he should not commit to posting it on to the internet in the first place. Once such a transaction has been established, it is in public view. Some people wish to subject us to a bunch of silly laws for to further their own greed and cause problems for the rest of us. I say get rid of those silly people and make them publish books.
HO HO HO! Hope you got lots of toys under your tree, a bunch of kids ripping paper everywhere, and the kitty cats having a ball with the torn up paper, or dogs, or whatever you have around the house! Thanks for the cookies and milk! Yum, yum!

To me it doesn't look like Microsoft is violating any valid patents; however, they seem to be really attempting to start taking over yet another market. In otherwords, twenty years from now, we will all be working for One Big Company, and Bill Gates will be our innovative leader. Somehow this reminds me why we fought World War II.
I have to watch CNN at work and the way they report makes me sick. Rather than giving references, they cave in to cheasy and dubious leads: "Sources say..." "The FBI says..." "Officials report..." That's the only thing that seperates it and the daytime talk shows.
When is CNN going to do any actual reporting, rather than following up on press releases by contacting the obviously biased three letter agencies? Many stories I have seen where I knew some background, they have screwed up. There are exceptions, where adventurous reporters really mingled with the communities involved. But that's rare. I get to see CNN Headline News rehash what looks like government and sponsor approved spineless news.
Further, they have to sensationalize on any blood and guts violence and terrorist related thing and hype it up like the world is going to blow at midnight, December 31st.
Maybe some good old fashioned news reporting and none of their constant speculative biased editorials would be a welcome change. Why don't they pick up local news events from city television stations that are always interesting? Why do we have to watch them stir up the hornet's nest on breaking problems and take the side who has the biggest media relations staff? They keep on reporting on events like compost that doesn't quite yet have a chance of into anything fruitful while they take sides.
Why does everyone do Quicktime? Is the encoding format pushed heavily or something?
I would be happy if there was more media based on something I can watch. Even at work where there are NT4.0, 98, and 95 machines, I can't watch this stuff. At least xanim doesn't crash my Linux box while trying. Most of these movies go unwatched.
Just time in milliseconds the ammount of time it takes on something you know that dosn't have the watermark to something that does...
Yes, and this can be measured down mighty close to individual clock cycles directly from the image passes. If a greater precision of software analysis is needed and the extra hardware at hand, just feed the sensor data from a previous pass. From there, a single branch of excecution would yield a detectable delay of output on the changed image.
Paper. Someone needs to tell the spooks and manufacturers to leave my scanners and printers alone so my artwork will not be compromised.
Whatever happened to gold and silver currency anyway? Nothing beats the fascination with gold. Paper just don't cut it. It can be copied, cut, shit on, etc. Gold can always be given as a gift, reworked, melted, but it will always retain its lust. There are many metals that can be compared to gold. I work at a copper power cable and wire manufacturing plant and if I stare at the product long enough, I feel like I have walked through Fort Knox. If 1,000,000 pounds of copper could be made into gold...
There's always a hardware solution for compromising software.
Just use mirrors, lenses, and perhaps filters to change the aspect ratio. Do you really think typical DSP software is engineered to a high degree to prevent crafty circumvention?
Say, on a scanner, have it scan an image that is shown to the sensor as twice its size with a color filter for multiple passes. Then have a software script clean it up. The final scanned image will look better this way anyway...
Now, if you wish to print that stamp collection out on your compromised printer, you have a few options through hardware. A simple way to fool the software, like the green of money, is to shift the colors, say green to red, red to blue, and blue to green, and do this to the print head connections after your software conversion of the image. If its pattern based, say those grovy lines on certificates that is being detected, why not invert *everything* and put inverters on the printhead? Now, for that, you will need to filter your image so the dots shoot out at the right contrast.
Hey there's a black van outside, let me check to see who it is...
olographic images to which there is no consumer equipment to duplicate
Could holograms lead to a false sense of security? Would money imprinted with holograms be ultimately secure?
With some basic equipment that can be purchased from any number of scientific supply catalogs, I could create my own holographic images in a homebrew photo lab. Now, they won't be identical by any means. A good side by side comparison would reveal that they are indeed very different. However, to the average person who notices a fancy schmancy hologram won't have the memory of the detailed original hologram.
Are there any effort going on at reverse-engineering/removing this 'feature'? I assume that since it's been known for years, and simply not publicized, that somebody has been working on this.
Well, if you notice your printer or scanner is doing some funny identification stuff on your work, let me know.
Imagine a scanner as an optical sensor that scans a page. The sensor will output this raw information to a processor, bit by bit for the image. If you have a patterned image, the stream will reflect that image. You can make your own test equipment from a number of programmable microprocessors out there and recreate this image. From there, compare it to what the scanner puts out.
Same with printers, except there is lots of math involved to optimize the the non-linear ink jets and static attractions on laser jets. It all depends on how much time you want to spend tracing the process.

FUCK YOU YOU IGNORANT PIECE OF SHIT.
This person had a bad cup of coffee this morning.
They gona try to hit you up for httpd logs? To bad crond cleans them once a week...right? :)
Not for my "small" ISP. My ISP rotates the httpd logs every 3 to 6 hours, due to the sheer size. Several megabytes per log is a lot of grepping.
Oh so it's okay to create XXX that will cause widespread piracy?
Better ban the photocopier then... those damn copies of books are overflowing my bookcases I tell you...
Those damn pirates! They hijacked my ship, pillaged my treasure, and raped the women! Someone must make a restraining order against them!

Yes, you can still print your own money. For now.

Be sure to buy your scanners and printers with cash.
However, your family pictures will bear the mark of mathmatical noise. This is what its all about. Do you want your baby's picture to be tainted?
