  1. WAV ? on New Arduino Due Brings More Power To the Table · · Score: 4, Interesting

    "It can even play back WAV files without any help."

    Well, ZPUino does this for a long time (14.4KHz, stereo, and more), and it's also opensource (actually, BSD for hardware, and GPLv2/v3 for software). Runs at 96MHz, and it's fully customizable (even the chip is customizable: see SoundPuddle for example, or the Rectrocade synth).

    What Arduino users were actually expecting (well, I was), was a proper IDE. I don't think writing proper applications for the Due platform with current Processing IDE is feasible. So far everyone has been quiet about this (there were rumours other IDE would be on the forge).

    But the price tag is indeed attractive.

    What is the rationale behind $1,370,590.00 ?

    I don't have the time or patience to read all the legal gibberish, wondering if someone can elude me if:

    b) The defendant took an unauthorized copy, used it, and also distributed it,
    c) The defendant took an unauthorized copy, and allowed others to retrieve it [and eventually used it]

  6. Re:Awesome on HP Making webOS Open Source · · Score: 1

    Sorry, I have to disagree with you, at least in the present time.

    I've been using some Web apps (javascript, html5, you name all techs involved), like floorplanner and upverter, and I find them barely usable. My computer is not however a high-tech one (Core2 Duo T2300 @ 1.66 Laptop, with Nvidia GeForce Go 7300), but it's specs would be *more than enough* to run such simple applications.

    Perhaps the problem is not JS itself, nor HTML5. Perhaps the problem is we're using a technology which was not meant, on the first place, to do what we are doing with it.

    It will take some time (and some standards) before we get Web Applications that can actually behave like native ones. But, my friend, it's not the time yet.

  7. complex routing ? on Raspberry Pi PCB Layout Revealed · · Score: 5, Insightful

    At first glance, this looks like a normal routing with a 4-layer board. Eventually 6, if you add proper ground + power.

    There's nothing indicative of PCB parameters, like drill sizes, clearances, blind/buried vias, minimum trace width, so on. Again, a simple look reveals nothing but common parameters for PCB.

  9. Baffling to users ? on Fedora Aims To Simplify Linux Filesystem · · Score: 2

    most passionate partisans will admit that its filesystem, which stashes vital files in a variety of arcane directories, can be baffling to users.

    Isn't that [directories] what filesystems are to provide, so things can be well organized ?

    Calling them, current UNIX/Linux filesystem hierarcy, "arcane", baffles me. Unless you're Poettering, of course. There is a good reason for things to be where they are, and, due to recent increase of embedded systems, a much more valid reason to split different levels of files across different filesystem hierarchies (read /bin vs. /usr/bin).

    I can accept complains about "/opt" and "/usr/local" - they might not make much sense nowadays, but if you happen to need to bootstrap from a read-only 8Mb flash device, and need to have a somehow working system before you access some external data,

    or

    you have a huge shared filesystem where a few servers rely upon, and you don't want to replicate all system files,

    then I see no reason at all to change this.

    Actually, perhaps increasing the diversity of directories might come in handy (like in /usr/i686/lib + /usr/x86-64/lib + whatever you might need, and with eventual optimizations, and with eventual debug).

    Or is this discussion only about directories which reside on the root of the filesystem ?

  10. ARM is not needed on ARM-Based Arduino Competitor At SparkFun · · Score: 2

    I actually had some conversation yesterday about this [having ARM powering microcontrollers and small embedded].

    I don't think this will succeed, and I believe there are a few reasons for it. I also created an "Arduino" clone, based on a different processor, called ZPUino, and although the programming environment, libraries and so on can be nearly the same, specifics to the SoC are always tricky to implement and to provide viable alternatives.

    Why standard ARM will not replace Arduino:

        * Lack of internal ADC
        * Power consumption
        * Latencies and jitter in execution path and in memory access path. This is very important.
        * Lack of proper GPIO and common Arduino devices (timers, PWM, so on, so on)
        * You cannot build one yourself.

    Arduino follows the KISS model. Introducing complexity here is not welcomed. Arduino is meant to be used by non-experienced programmers, hardware hobbyists and DIY aficionados.

    Why would you use an ARM, with a few megs RAM, a few megs flash, to blink a LED ?

  11. Re:Sounds cool on Inside NVIDIA's Massive Hardware Emulation Lab · · Score: 4, Informative

    Also, "gates" probably refers to Boolean logic gates.

    I think the term "gates" is abused and misused here, and in other articles. Not everything that goes on chip is a "logic gate", not even "gate", and they ought to be simulated as well. Think about clock modulators, PLL's, DCMs, for example. Other more esoteric thing exists.

    Doing a transistor-level simulation is also very expensive here. This is usually done on the low-level blocks only (and perhaps before going into silicon).

    What you simulate most of the time is RTL - Register Transfer Level. This includes not only plain logic paths, but synchronous elements like memories, flip-flops, and others.

    Being used to RTL simulation (I do a lot), those numbers are absolutely impressive. I often spend an hour simulating only a few microseconds. And the outputs of simulation are *huge* - imagine you have 1 million signals on the chip, and your freq. is 1MHz. This means you will retrieve 1 million * 1 million signal data for a one second simulation.

    How does this differ from Goggle's embedded JS (AdSense, Analytics) ? Why no one seems to worry about privacy on other sites, but insists that Facebook has severe privacy issues ?

    If you're all concerned about privacy, refrain from putting that information on the net. And that's true for *all* service providers out there, not only FB, not only Google, not only Microsoft. All.

    Besides, the /. article summary is completely biased. There is absolutely no reference to privacy concerns on the original article (except in comments).

    For me, having the opportunity to put a FB-enable commenting system on my sites is added value.

    I don't think people realise that less than 2% of Linux users will actually download, configure and compile its own kernel.
    So it's actually irrelevant if changelogs or announcements depict whether high-risk security fixes were or were not applied.
    You, as a Linux Distribution user (Ubuntu, Debian, RedHat, SuSe, you name it) do not care about it. You just want to upgrade your system. And you will - if your distro maintainer sees any urgency to push this or that fix.
    And kernel maintainers (distro) happen to know exactly what's on the table. They follow the mailing lists, they follow bugtrackers.
    Even if a bug shows up relevant enough to cause panic among everyone, no one will update their systems by hand. Instead they will rely on "standard maintenance procedures", like running their favourite distro-specific upgrade program.
    Just like M$ Windows people do. And Apple. And just like everyone else.
    People still use IE6. People still use W95. People still use OS2.

    This one would give a nice large tattoo.

    This is a T-shirt sold at CERN.

    This equation neatly sums up our current understanding of fundamental particles and forces. It represents mathematically what we call the standard model of particle physics. The top line describes the forces: electricity, magnetism and the strong and weak nuclear forces. The second line describes how these forces act on the fundamental particles of matter, namely the quarks and leptons. The third line describes how these particles obtain their masses from the Higgs boson, and the fourth line enables the Higgs boson to do the job. Many experiments at CERN and other laboratories have verified the top two lines in detail. One of the primary objectives of the LHC is to see whether the Higgs boson exists and behaves as predicted by the last two lines.
