  • Understanding and developing web services

    - by Pankaj Upadhyay
    This question is in conjuction with How would you approach developing a Hotel Reservation System? The solution to a system with different interfaces(or clients i should say) is to go with developing a Web service and have other systems interact with it. I never had the requirement for developing a Web service so i am bit short on it. All i understand is that A web service is a system or application that performs some operations which may include modifying, sending or receiving data over a network using HTTP protocol. (Let me know if the understanding is wrong) Now, from the other question it's clearly understood that i need to develop a web service but i have no idea as to how should i go about it. My language of choice is C# and .NET Framework. Question:: How do we develop a webservice and which tools,technology and framework should i use for the same using C# language?? Question:: How can i interact with this from a desktop WPF application, Website and Mobile app

  • python, cluster computing, design help [closed]

    - by j dawg
    I would like to create my own parallel computing server. Can you please point me to some resources I can use to help me develop my server. Sorry, like I said I need help getting started. Yes, I am limited to python, I cannot use C. I am using a bunch of workstations and I want to use all the cpus in those machines. So what I am looking for is blog posts, books, articles that can help me develop my own client/server tools to send code from the client to the servers and spawn python processes based on the number of cpus. I know how to do the subprocessing/multiprocessing part of the program, I do not know how to create the server that will take the client's requests. I also need to figure out what is the best way to handle sending file data, like netcdf files or other spatial data. Any suggestions very welcome.

  • How To Create a Customized Windows 7 Installation Disc With Integrated Updates

    - by Chris Hoffman
    Do you want to save time when installing Windows 7? You can create a customized installation disc and have it perform an installation without asking you questions, integrate updates and drivers, tweak Windows, and remove Windows components. We’ll be using RT Se7en Lite for this – if you’ve used nLite with Windows XP or vLite with Windows Vista in the past, it works similarly. RT Se7en Lite is a sort of vLite or nLite for Windows 7.

  • How to Create AppArmor Profiles to Lock Down Programs on Ubuntu

    - by Chris Hoffman
    AppArmor locks down programs on your Ubuntu system, allowing them only the permissions they require in normal use – particularly useful for server software that may become compromised. AppArmor includes simple tools you can use to lock down other applications. AppArmor is included by default in Ubuntu and some other Linux distributions. Ubuntu ships AppArmor with several profiles, but you can also create your own AppArmor profiles. AppArmor’s utilities can monitor a program’s execution and help you create a profile. Before creating your own profile for an application, you may want to check the apparmor-profiles package in Ubuntu’s repositories to see if a profile for the application you want to confine already exists.

  • Creating an installer for a python GTK3 application

    - by Noam Gal
    I have just finished developing a Python 2.7 application using Gtk3 for GUI. My question is, how can I now create an installer for Windows, Mac, and Linux (possibly three different installers) for my end-users to easily download the application without having to download python and GTK and such. I have never created an installer from a python script before. I have heard that are some tools for this purpose (py2exe? pyinstaller?), but I wouldn't know how and what to pack with them in order for it to be able to use Gtk3. Thanks in advanced, Noam.

  • Clockwork: A 40,000 Piece K’Nex Ball Machine [Video]

    - by Jason Fitzpatrick
    You may have built a simple marble raceway out of construction toys like LEGO or K’Nex at some point in your life. No matter how grand a raceway it was, we can assure you it had nothing on this 40,000 piece room-sized monster. The creator, Austron, writes: This is Clockwork, my fifth major K’nex ball machine, and my largest and most complex K’nex structure to date. It took 8 months to build, has over 40,000 pieces, over 450 feet of track, 21 different paths, 8 motors, 5 lifts, and a one-of-a-kind computer-controlled crane, as well as two computer-controlled illuminated K’nex balls. For a more in-depth look at the construction we suggest checking out both his YouTube channel and his build blog.

  • Did anyone experience negative SERP movement after implementing rel=author?

    - by raam86
    I am not intrested in why I don't see the picture in SERPs. So I know this is borderline off-limits but I turned every stone in the web (including DDgo) trying to find anybody experiencing a worse position in SERPs after implementing rel=author tags. In Google Webmaster Tools: Everything seems fine but the first results dropped 14 places in SERPs in the past two days. The original landing page went down from first page to 5th page in a few days. It is a useful site with original content concerning marriage laws. This specific page is no where to be found and now the first result leads to the home page. Assuming everything else is the same with no changes made to the site at all is there a reason the rel=author tag will cause such a plummet? Additional info that might be useful: The google+ account is as dead as a palm pilot.

  • 3D transformations in WPF & DirectX/Direct3D or OpenGL

    - by user2723417
    I need your help with 3D transformations. I have a sphere and I want to deform it by a mouse click or a mouse move. I want to make a furrow or to bite off a piece of the sphere without any breaks of 3D material. It is possible in WPF, but if the quantity of 3D points is more then 25 000, it creates some freezes in a dynamic mode (animation breaks), because the object of MeshGeometry3D class should be reconstructed every time to stop the breaks of 3D material. Give me advice about tools for the realization of my task. Maybe it can be done with the help of DirectX/Direct3D or OpenGL? I am a newcomer in these collections of APIs, but I would like to study them. I need to integrate the process of transformation in WPF application.

  • Screen goes nuts and unreadable

    - by ChazD
    Running Ubuntu 10.10 in its own partition, also have Oracle Virtualbox 4 with Windows XP. Because i previously had a problem with a dark screen when i let the laptop on and i didn't use it for a long while i had set Power settings to Never sleep, never let the Display sleep. Monitor on install set to Laptop resolution 1400 by 1050, refresh rate 60 Hz, rotation Normal. The problem was when the computer was left on and i returned after about an hour, the screen was unreadable, similar to what used to happen to graphics cards before multisync became normal. So it appears as though the graphics card was asked to use a resolution it couldn't handle and went nuts. I had to power off the system, on restart everything was fine. Thanks for any suggestions.

When it comes to RAD application suites for managed web applications, there is non better than Iron Speed Designer. The ease with which you can create a data-centric web application and have different reports of your data within minutes are unparalleled.

  • Web framework for IPad and common desktop browsers?

    - by Chris
    We are developing a web-based, commercial point-of-sale application. We'd like the same web site to work well on an Ipad as well a desktop browsers. We're looking for a web framework that makes the site look good on an IPad, but also makes the site work well in a desktop browser such as Chrome, IE, or Firefox on Windows or a Mac. I found quite a few at 18 Mobile Frameworks and Development Tools for Creating iPhone Apps Most of them, such as JQTouch, help a web site look and act more like a native IPhone application but they don't emphasize the cross platform/browser experience. The exception seems to be Sproutcore, which seems to be a full-fledged javascript MVC application framework. I did have trouble getting some of the demos to work under Chrome, but what did work looks good. What framework(s) have you actually used to develop web sites to work on an Ipad and desktop browser? If you didn't use a framework, how did you get it to work well under both environments?

  • 8 Deadly Commands You Should Never Run on Linux

    - by Chris Hoffman
    Linux’s terminal commands are powerful, and Linux won’t ask you for confirmation if you run a command that won’t break your system. It’s not uncommon to see trolls online recommending new Linux users run these commands as a joke. Learning the commands you shouldn’t run can help protect you from trolls while increasing your understanding of how Linux works. This isn’t an exhaustive guide, and the commands here can be remixed in a variety of ways. Note that many of these commands will only be dangerous if they’re prefixed with sudo on Ubuntu – they won’t work otherwise. On other Linux distributions, most commands must be run as root.

  • Check Your Spelling, Grammar, and Style in Firefox and Chrome

    - by Matthew Guay
    Are you tired of making simple writing mistakes that get past your browser’s spell-check?  Here’s how you can get advanced grammar check and more in Firefox and Chrome with After the Deadline. Microsoft Word has spoiled us with grammar, syntax, and spell checking, but the default spell check in Firefox and Chrome still only does basic checks.  Even webapps like Google Docs don’t check more than basic spelling errors.  However, WordPress.com is an exception; it offers advanced spelling, grammar, and syntax checking with its After the Deadline proofing system.  This helps you keep from making embarrassing mistakes on your blog posts, and now, thanks to a couple free browser plugins, it can help you keep from making these mistakes in any website or webapp. After the Deadline in Google Chrome Add the After the Deadline extension (link below) to Chrome as usual. As soon as it’s installed, you’re ready to start improving your online writing.  To check spelling, grammar, and more, click the ABC button that you’ll now see at the bottom of most text boxes online. After a quick scan, grammar mistakes are highlighted in green, complex expressions and other syntax problems are highlighted in blue, and spelling mistakes are highlighted in red as would be expected.  Click on an underlined word to choose one of its recommended changes or ignore the suggestion. Or, if you want more explanation about what was wrong with that word or phrase, click Explain for more info. And, if you forget to run an After the Deadline scan before submitting a text entry, it will automatically check to make sure you still want to submit it.  Click Cancel to go back and check your writing first.   To change the After the Deadline settings, click its icon in the toolbar and select View Options.  Additionally, if you want to disable it on the site you’re on, you can click Disable on this site directly from the popup. From the settings page, you can choose extra things to check for such as double negatives and redundant phrases, as well as add sites and words to ignore. After the Deadline in Firefox Add the After the Deadline add-on to Firefox (link below) as normal. After the Deadline basically the same in Firefox as it does in Chrome.  Select the ABC icon in the lower right corner of textboxes to check them for problems, and After the Deadline will underline the problems as it did in Chrome.  To view a suggested change in Firefox, right-click on the underlined word and select the recommended change or ignore the suggestion. And, if you forget to check, you’ll see a friendly reminder asking if you’re sure you want to submit your text like it is. You can access the After the Deadline settings in Firefox from the menu bar.  Click Tools, then select AtD Preferences.  In Firefox, the settings are in a options dialog with three tabs, but it includes the same options as the Chrome settings page.  Here you can make After the Deadline as correction-happy as you like.   Conclusion The web has increasingly become an interactive place, and seldom does a day go by that we aren’t entering text in forms and comments that may stay online forever.  Even our insignificant tweets are being archived in the Library of Congress.  After the Deadline can help you make sure that your permanent internet record is as grammatically correct as possible.  Even though it doesn’t catch every problem, and even misses some spelling mistakes, it’s still a great help.
