  1. Re:Too bad they're not also pushing ... on Why Verizon Doesn't Want You To Buy an iPhone · · Score: 1

    The attempts by people to badmouth CDMA never cease to amaze me. The original GSM was based on the horribly inefficient TDMA. Basically, the phones took turns talking to the tower, even if they had nothing to say. You got the same limited bandwidth whether you were the only phone connected to the tower, or if the tower were at capacity. If there were more phones than timeslices, you couldn't connect, period.

    This is only true for active calls. Many more "idle" phones could be connected at once. There is a limit of 8 connections/cell (so usually 24/tower).

    CDMA allows all phones to transmit simultaneously, they just use orthogonal codes which allow the tower to decipher which signal came from which phone. It's computationally more expensive, but it allows a single phone to use all the bandwidth if there are no other phones, while distributing the bandwidth equally if there are multiple phones. If there are more phones transmitting than bandwidth, you start getting dropouts (the volatility of SNR means there's no hard limit at which this happens, as with TDMA).

    Completely true.

    When carriers started adding data services, GSM was borked due to TDMA's inefficiency. That's why CDMA carriers rolled out 2G and 3G service about a year sooner than GSM carriers. GSM was forced to graft on a separate non-TDMA radio just to handle data traffic. (This is also why you can talk and use data simultaneously on GSM - the phones have two radios, one for voice, one for data. It's not a feature; it's a side-benefit to a fix which CDMA never needed. Most CDMA phones just have one radio which handles both voice and data.) The later GSM 3g data protocols used wideband CDMA. That's right, CDMA won - it was the better technology for data. GSM just incorporated it into their standard so it was still called GSM. If LTE is CDMA functionally dead-ending, then GSM dead-ended way back when cellular data services were first added.

    No, GPRS (GSM's data bolt-on) does not need a separate radio. It uses the free timeslices (not used for voice) for transferring data between the handset and cell (tower). So if all of the 8 timeslots are busy, no data. If no one is talking, then you can (theoretically) use all that for data (though most phones have a limit of at most 4 or 5 of the 8 timeslots).

    Actually I find analog gauges much more useful in cars. I don't want to have to interpret digits.

  3. Re:A pity Framework isn't revived this way on IBM Donates Symphony Code To Apache Software Foundation · · Score: 1

    Sounds great, but many users have difficulty separating form (presentation) from content (data). Unless this separation can be done seamlessly or can be easily done incrementally, there's no chance if something powerful like this catching on. I mean, do you realize how many quite intelligent people still use word processors like a typewriter? And truthfully, sometimes that is the fastest and best approach for a one-off job.

    No, direct deposit means the company transfers money (an employee's salary) directly to the employee's account. No checks involved. Prevalent in Europe--there's really no other common way to get that (legal) salary payment. Really, aside from novely checks, checks here no longer exist.

    I'm sure Vista would have a share greater than 24% of Internet-connected if people could actually manage to connect to the Internet. Seriously, I've worked with many OSs and Vista is the only one where my wireless network didn't just work. It seems to work on every other reboot. Thankfully the cable works (once I managed to dig it out).

  11. Re:Potential for Netbooks on Web-based IDEs Edge Closer To the Mainstream · · Score: 1

    Install sshfs. Then you can use a locally-installed editor (both emacs and vi work fine, as do others) to edit those remote files. Works great and needs very little bandwidth and even works with intermittent connections, such as trains rolling through the countryside. The newer Gnome gvfs with fuse export achieves pretty much the same thing and I believe KDE has had something similar for a much longer time.

    Alternatively, emacs supports direct sftp access, but that's not as convenient for me.

    Compiles go through a remote SSH session.

    So why is it that when I cycle and obey the laws (really, I do), do I have to put up with people treating me like you just described? I drive a car, too, and also hate cyclists that not only break the laws but also behave dangerously. But believe me, plenty of people in cars do that, too but you just don't notice it in the safety of a car.

    I currently live in Zurich. I've lived in many other cities, visited some more, and Zurich has by far the best public transportation I've seen anywhere. Personally, I don't like having to search for parking spaces downtown or in the closer suburbs--these are the places where public transport has an edge and is more flexible, in my opinion. A car is useful sometimes. I just rent it then, and this occasional cost is still much less than the cost of owning a car.

  17. POP3 vs. IMAP on Why Email Is Still The Most Adopted Collaboration Tool · · Score: 1

    For unconditional email downloading, POP3 is slightly more efficient and easier to implement, but IMAP was designed with a clear separation between the headers and message body. This separation becomes most useful for accessing email from different clients. Which means that you can choose not to download that 500MB email, or download it only after you've read the smaller emails.

    The switching is between GSM/UMTS networks and WiFi alright, but not just any WiFi network. It must owned by a (mobile phone) operator with their equipment on it. You get nominally the same service as on their radio network (including data encryption, authentication), albeit faster packet data transfer--and you also get charged appropriately. It's just a different air interface.

  19. Re:recycling bath water for toilet flushing. on Hardcore Waste Recycling · · Score: 1

    Many toilets in Europe have two modes of flushing. However, the whole method of flushing differs: there's only a small amount in the bowl, and the water from the tank rushes down and does the flushing. In US toilets, the water from the tank causes the water in the bowl to swirl, which then causes the flush. You need a certain amount of water in the tank to enable effective swirling. So it'd be hard to design a US-based toilet with two modes of flushing.

    There's always XMX - An X Protocol Multiplexor, but I couldn't get it to work when I tried it (though I didn't waste too much time). The only "fault" is that you must run your primary session through it if you want to later have windown appear on many desktops. Dunno about its overhead. I just use x0rfbserver when I'm in a bind.

  23. Re:Jarre had this... on Building String Instruments with No Strings? · · Score: 1
    Musically speaking, the instrument was very limited; it was the equivalent of your run-of-the-mill-Casio-cheapo no velocity, no aftertouch keyboard. Beam free or beam cut, that's it. Very easy to implement in MIDI. What would be *very* cool would be to use the vertical position of the hand (the height at which the beam is cut) to modify factors such as signal amplitude (volume/tremolo), slight pitch alterations (vibrato), wave shape, etc. A hell of a lot harder to implement, but very interesting.

    If you put two lasers and sensors almost together (with maybe 1mm distance), then you could determine how fast the player's hand plucks the string. You can then use this data to modify amplitute.

  25. Re:Try a film or camera shop on 8mm Film Transfer? · · Score: 1
    If they don't offer a direct MiniDV transfer, you can get a VHS transfer and then use a MiniDV camcorder with analog dubbing capabilities to go from VHS to MiniDV. I've tried this personally with our tapes, and you shouldn't lose anything along the lines of quality because the original film will be the limiting factor.

    Do not go through the VHS route. My friend did this and the resulting quality was awful. Film has a much higher resolution than VHS.
