    I couldn't disagree with you more.

    First, I can't believe that you really believe your facile, Hollywood fairy tale of the crafty bank robber. We have bank robbers in the region where I live. They are usually poor and desperate. The successful ones use a gun and a mask and a getaway vehicle. They aren't gaming any system.

    Second, I know for sure that the people who championed the Patriot Act are the same people who now want to subvert the overwhelming will of the American people and legalize torture.

    Third, the Patriot Act was rushed through a panicked Congress six weeks after the 9/11 attacks. Most members of Congress didn't have time to read it all, let alone analyze it carefully.

    Fourth, my first post in this thread was to correct an apparent misconception that the government still needed probably cause to tap phone conversations. The fact that there is still a lot of confusion about what the Patriot Act really does, combined with the fact that it was rushed through Congress imply that part of the reason some people support it is because they don't really know what it does.

    Fifth, the real debate over the Patriot Act is not about bank robbers versus terrorists. One real debate would center around whether provisions in the Patriot Act violate the 4th Amendment of the Constitution.

    A better debate would center around Benjamin Franklin's prophetic:

    They that would give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
    You would need to show that the provisions in the Patriot Act would actually be effective in preventing the Hollywood styled terrorist act you proposed. Whatever added safety is provided would then have to be compared with the very real threat of the Patriot Act being misused to stifle politic dissent.

    History shows us that every police power that has been enacted has also been abused. In my opinion, the Patriot Act clearly violates the Constitution and is a very dangerous step towards the USA becoming a police state. The measures in the Patriot Act would have done nothing to help prevent the 9/11 attacks although it has already been used against non-terrorist political groups in the US. I think it must have been named for the Patriot Missile which was famous for never hitting its intended target.

    A Google("patriot act" wiretap warrant) led to this page, which says:
    The Foreign Intelligence Surveillance Act (FISA) regulates the FBI's collection of "foreign intelligence" information for intelligence purposes. Under the Fourth Amendment, a Title III warrant to intercept a communication must be based on probable cause to believe that a crime has been or is being committed. This is not the general rule under FISA: surveillance under FISA is permitted based on a finding of probable cause that the surveillance target is a foreign power or an agent of a foreign power, irrespective of whether the target is suspected of engaging in criminal activity. The USA PATRIOT Act expanded law enforcement authority to conduct searches and obtain communications under Title III, and also rolled back the already lax restrictions on the FBI's ability to gather information about individuals under FISA.
    And from this page:
    [...] the PATRIOT Act specifically lowers the threshold for obtaining a full collection warrant for Internet traffic. Instead of needing probable cause as required by Title III, the FBI now only needs to show that the information to be gathered is "relevant to an ongoing criminal investigation." That is a much lower standard than showing probable cause that a crime has been committed.
    Clearly, probable cause to believe that criminal activity is occuring is no longer required. It appears that warrants are still technically needed but the requirements are so lax they make the need for a warrant a mere fig leaf of decency.

    I fully agree with you.

    My paragraph that you quoted was an oversimplification. The post I was responding to was claiming that a near infinite sampling frequency was needed to perfectly sample a finite bandwidth signal. That post also specified a "purely theoretical" context.

    I'm confident that you will agree with me that after all of the real-world engineering details are taken into account, a finite bandwidth signal can still be captured with a finite sampling rate although that rate needs to be higher than twice the highest frequency in the signal due to the engineering concerns.

  10. Re:Shannon Sampling Theorem on 200gb Hack for iPod Nano · · Score: 2, Informative
    Your argument is based on jumping around between three different domains:
    • Mathematics
    • Physics
    • Engineering

    You raise the problem of quantization error without mentioning signal to noise ratio. In the real world the signal to noise ratio is never infinite in analog systems. If the quantization errors are random and are well below the noise level in the analog parts of a system then they can be treated as a small component of the analog noise and they don't significantly contribute to any imperfections in the signal.

    You say "humans have limited response to frequencies over 20 [k]Hz". My own tests and tons of scientific studies have shown that humans have a limited response to signals over 15 kHz and no response to signals over 20 kHz.

    You go on to say " [...] even with band limited signals". All signals in the physical universe are time limited and band limited. The real world signals dealt with in audio engineering are even more limited. The only realm where non-band-limited signals exist is in abstract mathematics such as the field of Measure Theory. I've studied Measure Theory and AFAIK, it has no practical application in the real world, either in physics or engineering.

    Your point that all analog systems are eventually non-linear is a good one. Unfortunately that is one of the key arguments why digital computation and reproduction is superior to analog. Your point is also misleading because you do not include the fact that all analog systems also have a finite signal to noise ratio and deal with a limited dynamic range of signals.

    Finally your point that it is often useful to use a sampling rate that is greater than 2x the maximum frequency in the signal is totally valid. This issue is discussed in the article I linked to in my original post. I'm not 100% certain, but I am pretty sure that this engineering limitation is one of the reasons a 44.1 kHz sampling rate was chosen for CDs even though to top range of human hearing was 20 kHz. That extra 10% was to allow for anti-alias filters with a gentle enough slope so that they did not significantly distort the signal in the time domain.

    I agree with you that anti-alias filters (on both input and output) are an essential part of a well designed digital recording system.

    My key point is that claims that physical real-world digital recording systems can't record abstract, mathematically perfect analog signals are misleading and perhaps meaningless.

  11. Shannon Sampling Theorem on 200gb Hack for iPod Nano · · Score: 4, Informative
    Your argument is compelling, intuitive and dead wrong.

    The Shannon Sampling Theorem states:

    When sampling a signal (e.g., converting from an analog signal to digital), the sampling frequency must be greater than twice the bandwidth of the input signal in order to be able to reconstruct the original perfectly from the sampled version.
    To put it into term that you can understand, if your ear cannot detect frequencies higher than 22.05 kilohertz then a sampling rate of 44.1 samples per second can perfectly reproduce any sound you can hear.

    Compaction itself costs but is only needed on those occasions when memory starts becoming tight. And it usually isn't needed at all in the "young" heap area, since the deallocated memory of other young objects can be reused for the next object in need of allocation.
    You've lost me here. Perhaps it is due to my lack of knowledge about generational gc.

    I thought the original article was boasting that Java gc allocation was very fast because it didn't need to walk free lists in order to allocate. Instead it just grabbed memory from the top of the half-heap that was currently active.

    How can deallocated memory be reused without the overhead of free lists?

    ShadowRanger said:

    The GC usually need not bring any dead data out of swap; certain data about objects is stored independent of the object to reduce that problem, so the GC can just tell the OS to free it (and keep in mind, the OS doesn't manually zero the swap space either, so both JVM and OS get to be lazy).
    I agree that the gc can tell the OS to free the unused half of the heap so the garbage in it need not be read back in from swap. But the gc will then need to ask the OS for a new huge block of memory, half the size of the heap. This means the OS will have move other active memory into swap in order to have enough space in RAM for both halves of the heap when the copying from one half to the other is occurring.

    Granted, the VM manager might be smart enough to do the freeing of RAM incrementally, it still seems to me that no matter how you slice it, if the heap is large enough, copying one half of the heap to the other half is going to require a lot of swapping.
