Linux Powered Stethoscope! 2,396

Did you ever think of how powerful Linux could be? In your daily lives? Yes? No?

Well, going one step farther than most students, [Rhythm Reloaded], four engineering students at Calvin College are designing an electronic stethoscope that will:

  • Record high-quality audio data from a patient’s body
  • Store this audio data in a convenient format
  • Use a USB interface to transfer the audio files to a computer
  • Reduce the amount of ambient noise that a doctor hears
  • Be simple, accurate, and easy to use!

(source:RhythmReloaded)

    The operating system of choice for the project is µClinux, a very small open source Linux operating system that will run from flash memory! Check out the really cool screenshots of the project and the kernel compiled here: Project page

    For those who don’t know much about the OS, µClinux includes kernel releases for 2.6 as well as user applications, libraries and tool chains. To learn more about µClinux and to see whether you can use it in an application somewhere ;) check it out at µClinux.

    Edit: I have been informed (via email by David of Rhythm Reloaded) that uClinux also has kernel releases for 2.4 (which they are currently using) and 2.0.

    Linux to heal IT budgets. 2,410

    Linux In 2004, McKesson Provider Technologies began focusing its efforts on ways to cut IT costs for customers, including hospitals and nedical offices.

    McKesson

    The cure they found and implemented was to switch to Linux! This made a lot of immediate sense since the money could be used to buy less expensive hardware available in the market instead of expensive mainframes. Today, the company offers around 50 applications ranging from billing to surgery scheduling to physician order entry systems runnning on Linux. They have also officially announced their partnership with the Red Hat Enterprise Healthcare Platform.

    The main cost reducing factor is the replacement of mainframes with basic servers running Linux. This showed immediate results as far as reducing the customer’s maintainence and operational costs. They have also offered their software to RedHat enterprise Linux! Estimates show that the switch allows the companies to reduce costs by around 60% when compared to what they were spending earlier.

    About 75% of McKesson’s customers are on board as far as the move goes although 15% still are dead against it. The main problem of course lies in the fact that Oracle is still the database that most legacy customers use and running open source alternatives like MySQL will take some time getting a share of the Oracle pie…

    Another Linux Business come good! Are the rest listening?

    Application alternatives on Linux. 2,123

    So you’ve shifted to Linux. You love it! And its so totally cool! But … you miss those happy days of using Nero or Adobe products or iTunes even…

    What do you do? You go to the nearest forum and ask your people for some answers only to get the same answer again and again … Google it!! You would love to do that once in a while but after sometime, you start regretting this helpless state of dependance that you are in and would rather go to your windows boot instead …

    Here comes the answer to your problems … well, sort of! There is a new site that has a almost complete database of all the alternatives that you ever wanted to know about! in a easy to search, easy to browse manner, even!

    LinuxAppFinder is the best resource that I have come across for a long time. In fact, the first page of LinuxAppFinder has all the Adobe products and their alternatives listed! (It helps that it is listed under ‘A’ :D ) So for all your Linux App needs, LinuxAppFinder is your place to go to!

    Desktop Linux Survey Results. 2,357

    The linux Foundation let out an early look at the result of their third annual desktop Linux survey. Key highlights of the report have been:

    • The number of users who filled out the survey has doubled to around 20,000 this year, compared to last year’s survey.
    • The survey users were mainly from Europe (51.5%), followed by North Americans (35.8%).
    • More than 39.5% of organizations that have Linux desktops are also running Linux on more than half of their machines.
    • The user baser for Linux is slowly moving towards client desktops as opposed to being inclined to development or engineering related work.
    • The preferred distribution for users has been Ubuntu (54.1%), followed by Red Hat and SUSE.
    • Some other really interesting observations have been that Linux users want to use software like AutoCAD, Photoshop and Dreamweaver on their Linux installations. Another really interesting observation is that more and more users are moving from a dual boot to a native Linux only system.

      Major concerns have not changed that much, however. The major issue as of this writing remains device support, especially for WiFi network adaptors. The issue with printers has become a little less, but users want to be able to use the kind of functionalities and additional features that they get with modern printers and multi-purpose machines.

      More information on the survey as soon as the survey results are announced after November 30th.

    Finding text in files 2,065

    Because of our being forgetful in nature, we oftentimes forget the files that we have created. We can only be fortunate if we can still remember the path, folder, or directory where we have stored those missing files. If that’s the case, it would never be a big deal then. However, trully this a big problem and even painful if we can’t even remember where we have placed the missing files in our computer. “Simple,” I’m hearing you… “find it.” Yeah, we can find it. But wait, do you know the filename?

    Forgetting files and forgetting the filenames are most common in us. I will never believe somebody out there have a photographic memory and has never experienced missing some of the files he had created before. For sure, we all have gone through that frightening experience especially if the file that is missing is so precious to us.

    In Windows, this problem can easily be addressed just by using the find or search tool in the Start menu. Can you remember some texts or phrases in the filename? Use “find files with names” and unleash the power of the wildcard character (*). For example, if you can only remember the word “statistic” in the filename, then search for “*statistic*” and that will search for files with the word “statistic” in the filename. “I can’t even remember a word in the filename,” again I can hear you saying that. Well, I don’t think you can’t even remeber even a single word in the file content itself. If you can’t remember even a word or phrase in the filename then go for the file content itself. In Windows, still you can search for files containing some texts that you specify in your “find files containing text” input box. That will absolutely solve your problem of forgetting words in the filename itself.

    However, if you are in Linux, the whole thing would be more different and complex than it is in Windows especially if you are just a normal user dependent on the GUI interface. Linux is more on executing commands from a shell.

    So if you are a normal user and that you are facing the “missing files” problem in Linux, don’t worry, I will show you the most common methods in solving this issue:

    Find files that contain a text string

    grep -lir “text to find” *

    The -l switch outputs only the names of files in which the text occurs (instead of each line containing the text), the -i switch ignores the case, and the -r descends into subdirectories.

    Find files containing search terms on Ubuntu

    To find files containing keywords, linux has a powerful command called grep, which you can use to find the lines inside any file or a list of files.

    grep -i -n ‘text to search’ *

    List files containing text

    Used to recursively search a directory for files containing a string, output the names of the files and the line number. This will search all regular files in for.

    grep –with-filename –line-number `find -type f

    Installing packages (rpm) in Linux 1,955

    The RPM package manager is one of the most powerful command line driven package managers. It is free software and has many libraries that allow for it to be used for advanced development. RPM is a core component in most of the Linux distributions like Redhat/ Fedora, SUSE, Mandriva, Ubuntu, etc.

    So, for the first Linux basic tutorial, I thought it might be nice to start by writing about the most commonly used options of the rpm command…

    To install a downloaded package, once you are in the directory where the rpm file is, type the following command in the terminal:
    rpm -ihv RpmName.rpm

    To upgrade an already installed package, type the following command:
    rpm -Uhv package

    To delete a particular package:
    rpm -e package

    In case you want to reinstall a package which has deleted parts,
    rpm -i -force package

    That’s all for now. In case you feel that I have missed something, let me know!

    Transparent menus with Compiz. 3,070

    The Compiz (compiz-fuzion) is one of the coolest options available on a linux desktop! It has such an extensive collection of features (all configurable) that sometimes one just gets lost, I know I do!

    So here is a cool tip to make the menu’s and taskbar transparent.

      If you don’t have the Compiz config settings manager, install the compizconfig-settings-manager package.
      Launch the utility either from the terminal or from the Preferences menu.
      To set menu transparency, select the General Options tile and choose the Opacity settings.
      In the Window Opacities section, click on the Add button.
      The pop-up window opens up and asks for window specification and the opacity you want.
      In the Opacity field, input: Tooltip | Menu | PopupMenu | DropdownMenu
      Set the Opacity value to what you like, say 80.

    And that’s it. Of course you can do a lot more that just this basic configuration. To learn more, check out the documentation at the Compiz wiki

    Wal-mart sells out Linux PCs 2,119

    Wal-mart, which has been selling Linux PCs for some time now has officially sold out its stock of the Everex TC2502 PC which runs the gOS (linux). The reviews and ratings that this product has received from new and old Linux users has been really great and I am sure that this is the beginning of a long and successful run for the linux based PC.

    The Everex PC is the first mass marketed desktop PC running Linux and runs a “green” version of Ubuntu called gOS. The best part about the PC is the configuration:
    1.5GHz VIA C7 CPU in a mini-ITX motherboard
    512 MB of RAM
    80 Gb Hard Drive
    It also uses the new Enlightenment desktop manager, which the manufacturer claims makes the PC more responsive that a PC running vista. The PC also comes bundled with a long list of pre-installed Google products. To top all of this off, the users also get free phone support!

    Awesome is all I can say!
