    There is no difference between Winelib and Wine applications. This is a myth. It's about as much of a difference as linking a program statically versus using dynamic libraries. It's not noticeable from the end-user point of view. A winelib app can have just as many bugs and will be just as fast (or slow) as the wine version.

    Wine doesn't do conversions at runtime. It's not an emulator. Wine is a set of DLLs and a loader for PE files (necessary because Linux uses ELF). The reason nobody uses winelib is because it's completely pointless. Using DLLs is just as fast and tends to save a lot of space on your hard drive over static linking.

    I'm still confused about how something that I can hold in my hand is an idea, not a physical object.

    You can hold a CD in your hand. Does that make software a physical object?

    Algorithms, being nonphysical, are able to be copied much more quickly and at much lower cost than mechanical gadgets. This has led to a computer software industry that is racing forward at incredible speed.

    I fail to see why algorithms are necessarily easier or faster to copy than mechanical gadgets. The process of designing a piece of software and designing anything else is largely the same. Even if that is indeed true, I fail to see why it necessarily accelerates progress. I would also disagree that the rate of progress in the world of software is greater than that in other industries. Many industries have a high rate of innovation.

    Software patents limit this forward progress to the patentholder, slowing everyone else and hurting the economy.

    Well, you can always pony up the cash and license the patent. The theory is that it accelerates progress, because innovation is rewarded. Why is this untrue for software and true for other industries?

    No extra promotion of progress is needed in the world of software; companies and individuals are busy racing forward as quickly as they can.

    This is true of many industries. Competition from overseas is another major driver. In general, there is plenty of motivation besides patents.

    It's difficult to write a nontrivial program without infringing on some patent somewhere

    Only because the patent quality is very low. It would not be true if the USPTO did its job properly. However, this is also true of most other industries. There is always the possibility of infringing someone's patent. The theory is, you would negotiate a deal with the patentholder.

    Being in the business of algorithms myself, I see their bad effects more than I see the bad effects of patents on mechanical gadgets.

    This seems to be by far the biggest issue. People oppose software patents because they are in the software business. However, software patents really aren't significantly different from other patents. They cause the same problems in the electronics industry, and probably in the mechanical industries as well. The real problem is the horrible job the USPTO does approving patents, not patents themselves.

    I don't think it's even possible for Vonage to be anything more than a short-lived player in the industry. The thing that drives them now is the high rates the phone companies set for long distance, due to lack of meaningful competition. As soon as cable companies enter the picture, everything will change, and Vonage will be about as relevant as AOL dialup is today. Internet traffic doesn't support QoS, so Vonage's traffic always gets low priority. Right now, it sort of works because the pipes are pretty wide. However, it's not guaranteed by any means, it's largely determined by the internet provider, and VoIP does not really do anything for the underlying problem -- the high prices. The cable companies can guarantee excellent call quality and better uptime on their own networks, for the same price. This will drive Vonage out of business very quickly.

    OK, I might not have been too clear. Let's say you design a new type of amplifier that has better performance than an existing one. It's certainly patentable, and it's just an idea. Just because you might implement it with transistors instead of bits doesn't mean it's substantially different.

    For a variety of reasons, patents on algorithms impede progress and economic growth; they do not produce a net benefit to society, so they should not be granted.

    You have not presented a shred of evidence to support your assertion. If patents on algorithms do not benefit society, how do patents on mechanical gadgets benefit society? There isn't some kind of magical dividing line. It takes just as much ingenuity to come up with a novel algorithm as it does to invent anything else.

Circuits have always been patentable. I really fail to see why algorithms should not be patentable, so long as they are novel and nonobvious.

  16. Re: Convenience on Standby TVs Waste Electricity, How About ACPI? · · Score: 1

    It would take an awfully large capacitor to provide a reasonable standby time. The Sharp converters draw 100mA when transmitting, the 0.1mA figure is for the "shutdown mode". This makes sense, since an ordinary LED requires about 5mA to be visible and an IR LED needs to be very high-intensity.

    Even assuming a power draw of 0.5mA (unrealistically low, in my opinion), capacitors would not provide enough runtime with simple circuitry. Let's say you put in a 1F supercap, and let's suppose the standby circuitry can run in a range from 5V to 2V. You have a 3V window where stuff works. The dv/dt for a 1F cap discharged at a constant 500uA is 500uV/s (I = C dv/dt, so dv/dt = I/C). This means you are in the 3V window for 6000 seconds, or less than 2 hours. Even if you use a switching converter, you will still get maybe 4 hours of standby. Using a higher voltage is not an option, since inexpensive supercaps don't come in anything more than 5V or so.

    Also, it's impossible to turn on a relay with a capacitor the way you describe. Relays are far too slow for a capacitor of a reasonable size to energize one for the necessary length of time to connect the contacts and allow the main power supply to start up. A solid state device like a triac would be required.

    Actually, I don't think most modern TVs keep the tube warmed up. My TV takes the same time to turn on whether it's in standby mode or not. Nobody uses separate IR decoder chips, it's usually merged into the main ASIC and it's actually a microcontroller. If it's carefully optimized, it will draw about 0.3mA in sleep mode and a few milliamps when it runs. The real problem is the IR receiver (the ones I looked at draw 1-2mA), and more importantly the large relay which is supposed to switch on the main supply. It might be possible to solve this problem with something exotic, like a photo-triac, but it's definitely not simply a matter of putting in one capacitor.

    Actually, that's already how it's done, and that's exactly why a lot of power is wasted. A small, cheap transformer is usually a lot less efficient than a large one. A large transformer has thicker wire for the windings, so less resistive losses. It also has a higher-quality core, so there are fewer core losses. Of course, this is largely irrelevant, since the last time large transformers were used in consumer electronics was in the '70s. These days, almost all power supplies are switching types, whose efficiency is determined by their design and the quality of parts used. Since nobody really tries to optimize their efficiency, they can be extremely inefficient, and often very poorly designed. Most of them are made by Chinese companies who usually copy other companies' designs without even understanding how they work.

    I think a law to mandate maximum standby power consumption (or, even better, incentives to minimize it as much as possible) can do quite a bit. Right now, it is simply not a factor in the design of equipment.

    I agree that power waste is problem, but the fact is that most people can't afford the cost of electronics to fix this and yes people don't care.

    Exactly, this is why it is necessary to legally mandate that all new electronics follow energy use standards. There are already lots of similar laws. For example, all showerheads and faucets sold or used in new construction must have a flow rate of 2.5gpm or below.

    The loss in resources is great, but hell look at any light in your house and leaving it on (which many people do) will cover for a lot if not all of the standby power you are using, and that is if that is a flourescent bulb.

    So what, if you are already wasting lots of energy, it's OK to waste even more? Some bulletproof logic here.

    There are problems with power waste, but start with the things that waste more than the things that are horrible in terms of wastage.
