  1. Inaccurate blurb. on Visualizing Ethernet Speed · · Score: 2, Interesting

    anthemaniac writes:

    "In the blink of an eye, you can transfer files from one computer to another using Ethernet. And in the same amount of time, your eye sends signals to the brain. A study finds that images transferred to the brain and files across an Ethernet network take about the same amount of time."

    The amount of time you transmit data over a network depends on round trip time and bandwidth product, which determines TCP window size that optimizes the send/ack of data packets. You also need to take collision into account.

    The ganglion cells are probably more analogous to link transmitter. The measurement is on the amount of information generated by these cells per second. The proper conclusion is that you could probably use ethernet to connect the eyes and your brain, and the required bandwidth is supported.

    The curious thing is, Verizon, for example, allows you to get Business DSL at a residential address. Here you do pay $60-$70/mo. for a presumably better service. I'm okay with that as long as we're not stuck with $15 partial/biased Internet.

    But I do wish that sometime in the future, all business DSL plans are bundled with at least one static IP address. If it were phone, nobody would accept dynamic phone numbers (it changes everytime you pick up the phone). Why would people put up with dynamic IP addresses? It looks like we're actually moving backwards from voice to data.

  6. incentive on Cell Phones Presage Future of Non-Neutral Internet · · Score: 3, Insightful
    Those who want to eliminate neutrality dismiss this as alarmist, and claim that net neutrality would remove the incentive for broadband providers to build the next generation of Internet infrastructure, which all agree is sorely needed in the US.

    If having paying customers is not enough incentive to build the next generation networking infrastructure, I don't see what else is enough.

    The only case where non-neutral Internet makes sense is to have ad-supported Internet, so that content providers pay for end user's Internet bills from advertising revenue. If this is the case, then you get what you didn't pay for. But I don't see this coming.

    In the current model where end users do pay for their own Internet access, eliminating net neutrality actually poses risks to the ISP. If they happen to choose the wrong premium partner, they will lose customers. In fact, some people will be dissatisfied for every choices of partnership. Remaining neutral is probably the best way to make most people happy.

    I know I'm going to make myself unpopular, but bringing this to more awareness could help me clarify some of *my* misunderstandings too, so I rather do this now than regret later.

    The hypothesis is that man never landed on moon, and everything in the Apollo missing was staged on earth. The facts are presented in this video "What Happened on the Moon." There are two parts to this video.

    1. Part I: this part focuses on analysing NASA publicly released videos and photographs for fakeness. If the light shown in the scenes are lit only by sunlight, then all shadows should be parallel since the sun is so far away, that its rays are focused at infinity. Furthermore, moon does not have an atmosphere to diffuse ambient light, so shadow areas should be completely dark. The film is also constantly bombarded by solar wind and cosmic rays, so it would be badly exposed.

      None of the above mentioned phenomenon are observed with publicly released photographs. Rather, contradicting observations are found, namely non-parallel shadows, well-lit shades, and studio quality exposed pictures. You can look at official NASA images and videos on your on and decide for yourself.

    2. Part II: this part analyses rocket technology and radioactive shielding technology in the 1960's and concludes that these technologies are insufficient to actually bring human on the moon. Basically, they glued a German V-2 rocket to a space pod and claim that's what brought man to the moon.

    As you can see, my summary is more detailed for Part I than Part II because I have some knowledge and interest in photography, and I do not have much to say about rockets and radioactive shielding.

  12. colon in Mac OS X file names on Linux/Mac/Windows File Name Friction · · Score: 3, Insightful
    OS X supports up to 255 characters and can use the same characters as Linux, except for a colon (:).

    In Terminal.app, you can create file names with colon, but such character is mapped to a forward slash when seen in Finder. On the other hand, you can use forward slash in Finder, and it is mapped to a colon in the command line.

    Historically, Mac OSes use colon to separate folder names in a path.

    There is a subtle restriction in HFS+. All files in HFS+ have their names in normalized unicode, and in order to normalize in the first place, file names must be in valid UTF-8 encoding. You cannot use random character string for file names.

    There is no such restriction for UFS on Mac OS X. I think UFS supports roughly the same characters as in BSD and Linux and any other Unices. If you're transferring files from Linux with names in a legacy encoding, you can create a UFS disk image and convert file names to UTF-8 before copying them to HFS+.

    You don't "give up" rights as a child, you gain them in stages.

    In other words, you believe there exists no birth rights. What people have been talking about, free speech, privacy, etc. are privileges.

    In reality, you are right. Many people in different culture under different government never gained common rights in their lives, such as the right to travel and live wherever they want. In some countries, children grow up routinely subject to abusive punishments. I'm sure you'd agree with me that abuse in the name of punitive correction is wrong. Do these children have the right to be treated better? What if nobody ever gives them the right of better treatment? At some point, one has to decide whether certain rights should be inherent by birth instead of being later granted by someone or some institution. If you do not have any birth rights, you would easily fall victim to the agenda of certain individuals and institutions.

    But none of these are the issue.

    The issue is the great hypocrisy that you've been told you have certain rights, but you can't actually exercise them. Then what good are they? We should stop harrassing another government for violating human rights, but take a look at our own government. Can we really use the rights they claim we have?

    Even so, I'm not saying people are unaware of their rights. I know some of them, and I'm sure many people do much better than I. However, if you've never learned how to use these rights, you will not used them when situation arises.

    There is a difference between knowing your rights and exercising your rights. It's like, if you read about martial arts or saw it on TV but never practiced it, how would you suddenly know kung-fu when a thug shows up and tries to beat you up? You can read the constitution however many times you want, but if you don't practice, you won't be able to apply your rights.

    I worry that kids who grow up without knowing their constitutional rights will not ever learn to exercise them later in their lives. Unfortunately, taking a civil studies class doesn't help because the rights being taught in class hardly relates to the student's real-life experience.

    If you have been habitually giving up your rights since childhood, you will not hesitate to do so again when you're an adult.

    That is how I grew up. I can tell you, if I were stopped and interrogated by a police officer, I would let him search all over me, inspect my identification, all without a second thought. If the police showed up at my door, I would invite them in and let them look at all my personal belongings. That is because I was taught that if you didn't do anything wrong, then you should not be afraid to be searched. But searching without evidence of a crime is wrong.

    I never learned about any of these until I saw this video: How to avoid being arrested by cops. Anyone should watch this.

    If you're using Mac OS X on a PC, you need to know that most (illegal) images you grab on the net has some sort of patch applied to it in order to make it install and run on non-Apple hardware. The patches do not come with any reliability guanratee.

    Furthermore, the "original image" was most likely grabbed by Disk Utility on OS X, which results in a .dmg file. A third party program on Windows is used to convert .dmg to an .iso before patches are applied, so you can burn the resulting image under Windows. This conversion is error prone, probably more so than the patches themselves. Some people have had to try it a few times before they get a good "checksum."

    Sometimes the "original image" came from a developer snapshot (DTK) rather than an official release. A developer snapshot is inherently unstable.

    Considering all the disadvantages I mentioned above, if you're using Mac OS X on a non-Apple computer, you should not use this experience against Mac OS X itself.

    I thought "threaten" is a transitive verb: there is one person issuing the claim, another one receiving it, such that the claim has the nature that something harmful is going to be done on the receiving person. And I agree with the court in the sense that the intent of the claim nor the ability to carry out the claim are irrelevant.

    Define "threat" to be the claim that is being used for threatening. If the court admits this definition, then unless Aaron explicitly shows the AIM icon to that poor English teacher, then by definition this isn't a threat. This is simply because he hadn't delivered the claim, so the claim is not a threat.

We're constantly interrupted---by e-mail, IM, cellphones, blueberries, all those distractions---that we don't pay any attention to anyone at all. Because of this, people in general are not very good listeners anymore. This also contributes to the growing indifference towards other people.

    There are other reasons why we're all gradually feeling indifferent. For example, we all think we're getting smarter.

That's not unacceptable, but for a computer aimed at excellence in audio processing, this is a shortcoming, plain and simple.
