What device will be controlling the LEDs to make them turn on and off at the high frequencies needed to produce useful pulses of light? Transistors? What will be so special about those transistors that lets them switch the LEDs on and off at sufficiently fast frequencies, that we wouldn't just use those transistors for electrical logic signaling in the first place?

Those Newisys guys clearly have solid experience designing around the Opteron.

    Since Sun is already in the Opteron camp, none of this news hurts them. With the cheapness of x86 hardware, they can spin out Opteron workstations and servers at a fraction of the cost of their lumbering Sparc solutions, and the difference is pure profit. Even if it hurts Sparc sales, they'll be crying all the way to the bank.

    Remember, I was talking about a home theater system.

    That means multi-channel. That means you can't just broadcast to a single broadcast address. That means you have to configure the speakers so they know which channel they're on. They *could* use a hardcoded multicast group, and embed the channel ID in the audio data, but that would be inefficient and would require faster processors in each speaker, because they would have to sift through all the data to parse out the audio packets that are just meant for them.

    What delays are incorporated in the IP transport? And why are you even talking about IP as a stream transport? IP isn't a transport at all, it's a network layer, and its performance is pretty much dominated by the underlying media layer. If you had an IP speaker and a PC transmitter on two opposite ends of a crossover ethernet cable, there would be no switching delays, and wire propagation speed is the same as for analog cable. In fact you can deliver the data several times faster than realtime and let the speaker buffer it and play it back at realtime with its own jitter-free clock. Thinking that there may be delays just because they use IP is downright ignorant.

    Of course, to me what doesn't make sense here is the use of a bidirectional communications network for what is obviously a unidirectional job. Unless you plan to mount microphones in each speaker so they can report back balance and room delay characteristics back to the central console. That would be a smart use of technology, but I don't see anybody doing that.

    Good point. It's funny, the article starts with "Will computers that require no time to boot up become a reality?" but that's kind of a stupid question. I reboot my Linux machine once every year or so, maybe a little more often if I'm installing a new kernel. But once it's up, it stays up for weeks or months at a time. The time required to boot is totally insignificant.

    But the real point is, *when* I reboot a machine, I'm doing it because I need it to run from a clean slate. I don't want the previously crashed kernel and data to hang around.

    I guess many people perceive boot time as an evil thing because they have to reboot their Windows PCs so damn often. Just another case of fixing the symptom and not the real problem. The real solution would be to make Windows so reliable you don't need to reboot it.

    I don't think anyone is positioning this NRAM as a replacement for DRAM/SRAM. It's clearly only being compared to FLASH, so at most it's a contender for solid-state disk drive. And from the description, I would very much look forward to using it in that application.

All of these three packages support each other directly, out of the box. And likewise, since you can create a single LDAP user object with all of their Kerberos info, Unix info, and SASL info in one place, they naturally all replicate together. So there's nothing magic about OpenDirectory here. (Nevertheless, OpenDirectory is good stuff, and I'm sure it will be even better in the future.)

  13. Re:No free lunch. on Hydrogen Generating Module to Help Your Car? · · Score: 1

    Ah good point. Like the tZero electric car with regenerative brakes - driving down a mountain with a charged battery pack was a problem because they had nowhere to dump the power generated by the brakes. They needed to use up the battery before heading down the mountain. (Too bad they didn't take my advice and just use twin radio antennas on the back of the car, run as a Jacobs Ladder to dump the surplus.)

    But re: no free lunch - it is a proven fact that superchargers and turbochargers work to increase the power output of an engine, and they are spun by energy produced by the engine itself. So remember what you're measuring when you talk about there being no free lunch. The fact is that if you can increase the volumetric efficiency of the engine (through compressing the intake charge) you can produce more power than it costs to do the compressing.

    I admit I'm a bit skeptical about this idea, but if other people have proof that adding oxygen *and hydrogen* boosts engine efficiency, fine. The problem is that everything I know about combustion says that gasoline burns best in a 14.7:1 ratio (by weight) of oxygen to gasoline. Every modern car with electronic engine controls is pre-programmed to aim to maintain this stoichiometric ratio, and most of them do a pretty good job, at least when they're new. If you simply add oxygen to the intake charge, you get a leaner burn, which burns hotter and actually detonates, instead of burning evenly. And detonation (aka "knock" or "engine ping") destroys engines.

    There are newer engine designs that are specifically designated "lean-burn" engine designs, that apparently have specially designed combustion chambers that are less prone to self-destructing under high temperature conditions, but I don't think anyone is talking about them here. In any case, all that you need to do if you want to increase the ratio of oxygen to gasoline in the engine is program the fuel injectors to open for shorter intervals, thus letting in less fuel for the same amount of air. Presto, lean burn engine with more oxygen in the charge than normal.

    Since a modern car's engine control typically already meters the fuel flow to match the quantity of incoming oxygen (based on mass air sensors, exhaust gas pipe oxygen sensors, and various other devices / methods ) I would expect that the only result of dumping more oxygen into the intake charge like they do here would be to burn *more* fuel. That is, the engine controller will detect the leanness of the charge based on the sensor data, and increase the fuel injector duty cycle to compensate. You might get more power, but you can't get more *efficiency* from the burn - you still burn oxygen & gasoline at a 14.7:1 ratio, that's just the way the chemistry works.

    Now, having a bunch of free hydrogen in there as well may alter the reaction balance, but the net change ought to be zero since you're adding in a balanced amount of hydrogen and oxygen. That is, you started with
            2C8H18 + 25O2 = 16CO2 + 18H2O

    You added
            2H2 + O2 = 2H2O

    The added hydrogen and oxygen does nothing to the overall gasoline combustion reactions. How can it alter the "cleanness" of the exhaust gases? (I suppose it's possible, since none of these reactions run 100% to conclusion and there are side reactions producing CO and NOx. But if the added oxygen is offsetting these side reactions, where is the hydrogen going? Without oxygen to react with, it's doing nothing. And if it's reacting with the oxygen, then those side reactions keep occurring the same as before.)

    And another thing - what the heck are they talking about, feeling the tailpipe and proving that since it was cool to the touch, the hydrogen was doing it's job? The laws of thermodynamics have something disagreeable to say here...

    Look at the common stereotypes - techies or programmers for example. Think about professional programmers, getting paid by the hour, and what happens when they make typos in their code.

    For a C program, the compiler spits out a slew of error messages, of which probably only the first message is meaningful and the rest are spurious. After you've seen this happen a few times, the most common reaction is one of annoyance, swearing at the computer and/or compiler, while editing to fix all the problems.

    What observations can you make about this work cycle?
    1) "DWIMS" - Do What I Mean, Stupid! - programmers are quick to blame anything but themselves for their own mistakes.
    2) Programmers hate to have their mistakes pointed out to them.
    3) Programmers have extremely low regard for anyone/thing that points out their mistakes to them.
    4) Programmers being paid hourly make more money for making mistakes, and otherwise doing anything that stretches out the development time of a project.

    Once you understand 1-3 you can easily see how the same attitude transfers over into verbal communication. The fact is, a large number of supposedly savvy techies are lousy at paying attention to detail, whether communicating with people or with computers. With the computer work they can get away with being sloppy because the computer can only complain about bad syntax, and can seldom identify bad semantics, and they can take as many tries as necessary to tweak their input until the computer accepts it. With human communication you usually only get one shot at communicating a point, and these people who are too lazy and used to getting multiple chances to refine their output come out looking bad.

    Anyway, whether poor spelling or grammar reflects on your intelligence or knowledge or not, it certainly reflects on your attitude. And in most human interaction, that can be more important than any other factor.
