Book & software advice for creating a program that would utilize USB.....

Hey All,
I've been a mac user for about two years now and have become more and more impressed by the stability offered by Unix.
However, I still live in both worlds (XP and OSX) and my programming roots are windows based (sorry ).
Here's the problem:
I'm trying to determine which direction I should head for writing a program that gives me access to the USB ports on a Mac, and allows me to correlate it to a web atmosphere.
My thoughts are: I'd have a device attached to a USB port (or multiple), and I'd use a system (OSX) USB driver to write to a database, in turn - use dreamweaver to build a WEB that interfaced with this database.
I'm not sure what software I should use to write an app that can talk to my USB ports, as well as load them into a chosen database. I think once I have the data collected into a database, I can handle the WEB side of this, but I want to take this one step at a time.
I installed Xcode and I was ready to take off when I said - "wait a minute, this isn't exactly visual studio." [even though it's somewhat similar]
My programming background is in C++, VB and ASP (with VB script & Java Script) but I haven't written for about 3 years (hence the ASP and not ASP.net) - So feel free to steer me in the right direction or just give me a general verbal tirade and tell me I'm in over my head! LOL
I've bounced all over these message boards, and see everything from opinions on Java, C, C++, even Python (which I never heard of until a post yesterday: http://discussions.apple.com/thread.jspa?threadID=133836&tstart=0)
I'm asking for some advice on what books would be a good aid for me to purchase in order to help me achieve what I'm trying to do. I stopped in at my local Border's bookstore the other night, and there was quite an array to choose from.
So here is what I almost picked up for a starter:
http://www.amazon.com/gp/product/0764584111/103-2161547-3122203?v=glance&n=28315 5&n=507846&s=books&v=glance
Any suggestions?
Another major thought in my mind is the transition to little endian, which is what Intel uses (vs OSX big endian). Obviously, I don't want to get burned by this if I flip the wrong bit after the architecture changes....
I realize I may have really 'broad brushed' this, but I really wanted to hear everyone's thoughts since there may be other 'projects' I attempt to tackle on OSX.
Your suggestions on any books, sites, software, etc will be greatly appreciated......
Thanks for reading,
Steve

    In the detailed help for the event structure there is a link to caveats and recommendations for using event structures.  It is a good starting point.
    It is courteous to let the Forum know when your questions are related to a school assignment or homework.  We are glad to help you learn LabVIEW, but do not do your homework for you.
    You have learned the major disadvantage of the sequence structure: It must run to completion before anything else can happen.
    If you are building a state machine (typically a while loop with shift registers enclosing a case structure with one case per state) and having trouble with timing, then think about your requirements. Apparently you have some time delays, but under certain conditions you must terminate a delay/wait and do something else.  One way of doing this is to have a Wait state.  The wait state has a short delay, determined by the minimum time you can delay responding to a changed condition, and a check to see if the required elapsed time has occurred.  If the time has not elapsed, the next state is the Wait state again.  The state machine can repeat any state as often as necessary.  So a 15 second delay could be implemented by going to a Wait state with a one second wait 15 times. Any error or new command will see a response in no more than one second.

  • Idea for channel subscription program that would benefit MILLIONS of Verizon subscribers

    Hello, Since Verizon is moving towards allowing customers to create their own TV packages to compete with streaming services, I have an idea that would certainly please millions of users. If I want to subscribe to HBO or the French channel, for example, all I have to do is press a button on my remote. However, if I want to cancel these channels, this necessitates a phone call to customer service. The benefit of streaming services is that we can't watch everything at once, so why pay to subscribe to 10 channels, when you can't possibly watch them all within the same month. I think that each time you subscribe to a channel (be it Showtime or the Russian language package), you should be charged a one-month minimum fee. You can cancel the subscription (online or using your remote) at any time, but you still pay for at least one full month. That way, I, for example, can subscribe to the French channel, watch it for a month, then cancel, then subscribe to the Portuguese and German channels, watch them for a month, then cancel, then sign up for Cinemax, watch it for three months... Each network is still getting the benefit of a full month's subscription, plus people would be more willing to sign up (and try out) more channel options if they know that their minimum commitment is only one month. If you haven't guessed by now, I like to watch TV in multiple languages, but I can't sign up for all the channels at once because 1) it's too expensive and 2) I can't watch all these channels in a month. I'm sure other people would sign up for a movie channel package to catch up on their favorite shows (I think people do this anyway with Game of Thrones, etc.) or a sports package until the season is over, etc. In other words, by making it easier for people to cancel channel/specialty package subscriptions online or using the remote (with the understanding that there is a minimum of one month), more people would subscribe to these channels - and some would keep them for several months. With the addition of streaming TV, DVR programming, etc. there is just too much TV available and we can't watch everything, so fewer people sign up for pay-for-view packages. This model would give people more control over how they watch TV. True there would be a lot of turning channels on and off (I, for example, would probably do this frequently). However, there would also be a huge increase in revenue from these channels, even if people cancel after one-month (then the onus is on the network to provide quality programming to retain the customer). Thank you for your time.

  • Both Chrome and Safari interrupt online streaming to request/demand an update for a PC program that doesn't work on Macs. What is going on?

    Both Chrome and Safari interrupt online streaming to request/demand an update for a PC program that doesn't work on Macs. What is going on?

    The update alerts are fake, and are intended to dupe you into installing malware or disclosing private information so that your identity can be stolen.
    You might get the alerts when visiting a website that has been hacked. Don't visit the site again. If applicable, notify the site administrator of the problem, but don't send email to an unknown party.
    If you get the alerts when visiting more than one well-known website, such as Google, YouTube, or Facebook, then they're almost certainly the result of an attack on your router that has caused you to get false results from looking up the addresses of Internet servers. Requests sent to those sites are redirected to a server controlled by the attacker. It's possible, but less likely, that the DNS server used by your ISP has been attacked, but you should assume that the router is at fault until proven otherwise.
    The router's documentation should tell you how to reset it to the factory default state. Usually there's a pinhole switch somewhere in the back. It may be labeled "RESET." Insert the end of a straightened paper clip or a similar tool and press the button inside for perhaps 15 seconds, or as long as the instructions specify.
    After resetting the router, quit the web browser and relaunch it while holding down the shift key. From the Safari menu bar, select
              Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. Do the equivalent if you use another browser. Open the Downloads folder and delete anything you don't recognize.
    Then go through the router's initial setup procedure. I can't be specific, because it's different for every model. The key points are these:
    1. Don't allow the router to be administered from the WAN (Internet) port, if it has that option. Most do.
    2. Set a strong password to protect the router's settings: at least ten random upper- and lower-case letters and digits. Don't use the default password or any other that could be guessed. Save the password in your keychain. Any password that you can remember is weak.
    3. If the router is wireless, or if you have a wireless access point on the network, use "WPA 2 Personal" security and set a different strong password to protect the network. If the router or access point doesn't support WPA 2, it's obsolete and must be replaced.
    During the time the router was compromised, you were redirected to bogus websites. If you ever connected to a secure site and got a warning from your browser that the identity of the server could not be verified, and you dismissed that warning in order to log in, assume that your credentials for the site have been stolen and that the attacker has control of the account. This warning also applies to all websites on which you saw the fake update alerts.
    Check the router manufacturer's website for a firmware update.
    If you downloaded and installed what you thought was a software update, ask for instructions.

    Based on the information that you have supplied, you have a Early or Late 2008 MBP.  Maximum RAM that it will accept is 6 GB with the following specifications:   200-pin PC2-5300 (667MHz) DDR2 SO-DIMM.
    The best sources for Mac compatible RAM are OWC and Crucial.

    If your needs are limited to those tasks then both Preview and iPhoto will fit the bill They are already on your Mac. There is a free download from Google called Picasa available here:
    http://picasa.google.com/
      It works much the in same manner as iPhoto. For some really heavy duty work there is GIMP available from SourceForge:
