  • Choice of node.js modules to demo flexibility

    - by John K
    I'm putting together a presentation to talk about and demo node.js to client-side JavaScript developers. The language concepts and syntax are not an issue for them, so instead I'd like to get right into things and show off node's abilities that differ from client-side scripting. There are numerous modules available in the NPM registry and many people have much more experience with the registry than I do. I'm looking for a selection of node modules based on recommendations from your experience that show a variety of uses for node that are practical, broadly useful and can be demonstrated with a small code sample without requiring much domain knowledge on behalf of the audience. Neat and impressive is good too - I can throw in a couple of shock and awe items for cool factor. To be fair, top-voted answers will get most consideration for inclusion. My hope is this will result in a well-rounded demonstration of node technology.

  • Accessing SQL Server data from iOS apps

    - by RobertChipperfield
    Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

  • Almost Realtime Data and Web application

    - by Chris G.
    I have a computer that is recording 100 different data points into an OPC server. I've written a simple OPC client that can read all of this data. I have a front-end website on a different network that I would like to consume this data. I could easily set the OPC client to send the data to a SQL server and the website could read from it, but that would be a lot of writes. If I wanted the data to be updated every 10 seconds I'd be writing to the database every 10 seconds. (I could probably just serialize the 100 points to get 1 write / 10 seconds but that would also limit my ability to search the data later). This solution wouldn't scale very well. If I had 100 of these computers the situation would quickly grow out of hand. Obviously I am well out of my league here and I have no experience with working with a large amount of data like this. What are my options and what should I research?

  • How to add a printer in gnome-shell

    - by artfulrobot
    I'm using Gnome Shell (although I'm not sure whether the "Printers" app is part of that or just part of Gnome). I go to "Printers" from the overview, click the + button on the bottom left, choose network and then see a message "FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall.". It's not auto detected anything. There's an Address box and a Search by Address tickbox, but neither seem to do anything. I'm frustrated because I know all the details of the printer, but have nowhere to put them in. Automation is supposed to make things easier, no? For example I know the printer is at lpd://10.67.5.3/lp1 but I can't put this in anywhere. Is there a GUI that works, or have I misunderstood how to use it?

  • iOS Support with Windows Azure Mobile Services – now with Push Notifications

    - by ScottGu
    A few weeks ago I posted about a number of improvements to Windows Azure Mobile Services. One of these was the addition of an Objective-C client SDK that allows iOS developers to easily use Mobile Services for data and authentication.  Today I'm excited to announce a number of improvement to our iOS SDK and, most significantly, our new support for Push Notifications via APNS (Apple Push Notification Services).  This makes it incredibly easy to fire push notifications to your iOS users from Windows Azure Mobile Service scripts. Push Notifications via APNS We've provided two complete tutorials that take you step-by-step through the provisioning and setup process to enable your Windows Azure Mobile Service application with APNS (Apple Push Notification Services), including all of the steps required to configure your application for push in the Apple iOS provisioning portal: Getting started with Push Notifications - iOS Push notifications to users by using Mobile Services - iOS Once you've configured your application in the Apple iOS provisioning portal and uploaded the APNS push certificate to the Apple provisioning portal, it's just a matter of uploading your APNS push certificate to Mobile Services using the Windows Azure admin portal: Clicking the “upload” within the “Push” tab of your Mobile Service allows you to browse your local file-system and locate/upload your exported certificate.  As part of this you can also select whether you want to use the sandbox (dev) or production (prod) Apple service: Now, the code to send a push notification to your clients from within a Windows Azure Mobile Service is as easy as the code below: push.apns.send(deviceToken, {      alert: 'Toast: A new Mobile Services task.',      sound: 'default' }); This will cause Windows Azure Mobile Services to connect to APNS (Apple Push Notification Service) and send a notification to the iOS device you specified via the deviceToken: Check out our reference documentation for full details on how to use the new Windows Azure Mobile Services apns object to send your push notifications. Feedback Scripts An important part of working with any PNS (Push Notification Service) is handling feedback for expired device tokens and channels. This typically happens when your application is uninstalled from a particular device and can no longer receive your notifications. With Windows Notification Services you get an instant response from the HTTP server.  Apple’s Notification Services works in a slightly different way and provides an additional endpoint you can connect to poll for a list of expired tokens. As with all of the capabilities we integrate with Mobile Services, our goal is to allow developers to focus more on building their app and less on building infrastructure to support their ideas. Therefore we knew we had to provide a simple way for developers to integrate feedback from APNS on a regular basis.  This week’s update now includes a new screen in the portal that allows you to optionally provide a script to process your APNS feedback – and it will be executed by Mobile Services on an ongoing basis: This script is invoked periodically while your service is active. To poll the feedback endpoint you can simply call the apns object's getFeedback method from within this script: push.apns.getFeedback({       success: function(results) {           // results is an array of objects with a deviceToken and time properties      } }); This returns you a list of invalid tokens that can now be removed from your database. iOS Client SDK improvements Over the last month we've continued to work with a number of iOS advisors to make improvements to our Objective-C SDK. The SDK is being developed under an open source license (Apache 2.0) and is available on github. Many of the improvements are behind the scenes to improve performance and memory usage. However, one of the biggest improvements to our iOS Client API is the addition of an even easier login method.  Below is the Objective-C code you can now write to invoke it: [client loginWithProvider:@"twitter"                     onController:self                        animated:YES                      completion:^(MSUser *user, NSError *error) {      // if no error, you are now logged in via twitter }]; This code will automatically present and dismiss our login view controller as a modal dialog on the specified controller.  This does all the hard work for you and makes login via Twitter, Google, Facebook and Microsoft Account identities just a single line of code. My colleague Josh just posted a short video demonstrating these new features which I'd recommend checking out: Summary The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Version 5.1.3 of ReSharper released

    - by TATWORTH
    Version 5.1.3 of Resharper has been released by Jetbrains. Download is at http://www.jetbrains.com/resharper/whatsnew/index.html The release notes are at http://blogs.jetbrains.com/dotnet/2011/02/resharper-513-is-released/ Whilst 5.1.3 addresses just a specific issue, if you are programming in C# or VB.NET and if you have never tried Resharper before, you should try it. When I first saw ReSharper in use, within a few minutes I knew that it was worthwhile buying my own copy. Since then I have used it at client site after client site and found it to be a very useful tool.

  • What is the situation about OpenGL under Ubuntu Unity and Gnome3?

    - by user827992
    In a GNU/linux distribution is usually installed Xorg as main graphical server, it operates with a client-server logic, a special windows is designate as desktop environment and this special windows can handle all the eyecandy stuff like decorations, icons and effects. The problem is that the latest UI heavily relies on hardware acceleration, Unity is an overlay on Compiz and the Gnome-shell also require an active driver for the GPU to work well: the problem is: on the same OS I can find multiple implementations of OpenGL who is handling my OpenGL buffer? how the OpenGL buffer is managed compared to the other windows? how can I be sure that my OpenGL implementation is glued to the hardware and is not related to the client-server logic of Xorg? For example I have tried the clutter library and I have only experienced problems under both Unity and GTK/Gnome, no problem under other OS.

  • Is there a point to writing in C or C++ instead of C# without knowing specifically what would make a program faster?

    - by user828584
    I wrote a small library in Python for handling the xbox 360's STFS files to be used on my web applications. I would like to rewrite it for use in the many desktop programs people are writing for 360 game modding, but I'm not quite if I should continue using C# or delve into C++ or even C. STFS is an in-file file system used by the xbox 360 and the job of the library would be extracting/injecting files, which could take noticeable amounts of time to do. What I know in C# comes from internet tutorials and resources, as would anything I learn about C++, so what I'm asking is if it's better to bring myself to a slightly lower-level language without knowing beforehand the features of the language that increase performance, or continue assuming that compiler optimizations and that my lack of experience will mean that the language I choose won't matter.

  • Services or Shared Libraries?

    - by Royal
    I work in an environment where we have several different web applications, where each of them have different features but still need to do similar things: authentication, read from common data sources, store common data, etc. Is it better to build the shared functionality into a set of services, to be called by the web apps, or is it better to make a shared library, which the webapps include? The services or libraries would need to access various databases, and it seems like keeping that access in a single place (service) is a good idea. It would also reduce the number of database connections needed. A service would also keep the logic in a single place, but then it could be argued that a shared library can do the same thing. Are there other benefits to be gained from using services over shared libraries?

  • If I release a program under GPL, do I have to continue to do so?

    - by Kos
    Consider this scenario: I am developing a program FooSuite that uses a GPL-licenced library QuuxTools I release the program FooSuite 1.0 under GPL Later on I discover that, for some reason, I need to licence the program to someone on different terms. Hence: I remove the dependency on GPL via QuuxTools, by either... rewriting the program not to use this library any longer obtaining a different licence for QuuxTools (if it's dual-licenced; see PyQt) I release FooSuite 1.1 under a non-GPL licence. However, FooSuite 1.1 is still a derivative work from FooSuite 1.0. I understand that it's not legal for a stranger to do what I did, but am I myself - as the owner of FooSuite - free from this restriction?

  • Still prompted for a password after adding SSH public key to a server

    - by Nathan Arthur
    I'm attempting to setup a git repository on my Dreamhost web server by following the "Setup: For the Impatient" instructions here. I'm having difficulty setting up public key access to the server. After successfully creating my public key, I ran the following command: cat ~/.ssh/[MY KEY].pub | ssh [USER]@[MACHINE] "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys" ...replacing the appropriate placeholders with the correct values. Everything seemed to go through fine. The server asked for my password, and, as far as I can tell, executed the command. There is indeed a ~/.ssh/authorized_keys file on the server. The problem: When I try to SSH into the server, it still asks for my password. My understanding is that it shouldn't be asking for my password anymore. What am I missing?

  • Symbol of VPNanytime is not shown anymore after upgrading from Ubuntu 11.04 to 11.10

    - by Aufwind
    Usually when I start VPN anytime (by calling a certain url in firefox) in Ubuntu 11.10 I saw a little "green symbol with a yellow lock in front of it" for the VPN anytime client near the clock. If I wanted to quit the VPN connection I just clicked on this symbol and hit logout/quit. Today I upgraded to Ubuntu 11.10 and the VPN connection works here fine too. But the symbol near the clock is not shown anymore. Is this a bug or do I have to set this up manually? And is there a way to quit the client perhaps by terminal? Currently I just do a restart, when I want the vpn connection terminated and that's kind uncomfortable. :-) Thanks for any suggestions!

  • 301 redirects in main navigation menu of WordPress website - is this okay for SEO?

    - by Lewis Bassett
    I want to allow a client to have a flexible way to configure the navigation menu for his WordPress website. To that end, I have created a parent page called "Navigation", which has child pages for each page to be displayed in the navigation menu. Those pages then get 301 redirected to the actual page that should be served. This means the client can create pages freely, and then set up redirects for them as and when needed. This is a really easy way for him to manage his main menu and it works well. From an SEO point of view, is this okay? Will the pages be indexed fine?

  • HTTP events? Is there a standard / precedent for this?

    - by user619818
    Our architecture is HTTP servers (custom written) which whereby custom clients send a HTTP request for some information and information is returned just as HTTP works. But we need a special custom 'extension' which is a request which is a subscription for receiving asynchronous 'events' on a resource. For example the client sends an http request subscribing for events on some entity. As the 'entity' generates events they are passed to the http server and the http server must then lookup subscriptions for that entity and send the event message to all subscribed clients. Hope that makes sense. So my questions are: Has this been done before / or is there a standard I should be looking at? If no standard, any suggestions on how to implement? How does a http server send an unsolicited 'message' to a client?

  • Questions about software licensing

    - by iwayneo
    I've been having a discussion about licensing and open source software. Basically - the other guy is saying that licensing is easy, if you're going to build a product you can use an (any) open source project and make money by selling that code. My issue is that say I create a website or app with a project that uses a GPL license the restrictions aren't so straight forward - correct me if i'm wrong on each of these scenarios: 1 - i create an iPhone app using GPL code and put that app into the appstore - the code must be freely available to people buying that app. 2 - i create a website that my client hosts - they must have access to the code. 3 - i create a website as SaaS that my client "leases" but does not own - though it is hosted on their infrastructure - they must have access to that code Am i right on each of those assumptions? Are there any other issues i should be aware of under any other licensing terms for other licenses?

  • Photo management utilities

    - by Frantumn
    I'm about to develop a web site for a new client. It's not going to be very intense, but one requirement is that, if possible, the client wants to be able to manage the photo gallery themselves. Since they are not technically savvied at all, I was wondering what utilities exist that provide a GUI for users to log in to manage photos. Can anyone make a recontamination? I haven't purchased the web hosting yet, so if your answer requires a specific type of host server don't worry, I am open to options.

  • How do .so files avoid problems associated with passing header-only templates like MS dll files have?

    - by Doug T.
    Based on the discussion around this question. I'd like to know how .so files/the ELF format/the gcc toolchain avoid problems passing classes defined purely in header files (like the std library). According to Jan in that answer, the dynamic linker/loader only picks one version of such a class to load if its defined in two .so files. So if two .so files have two definitions, perhaps with different compiler options/etc, the dynamic linker can pick one to use. Is this correct? How does this work with inlining? For example, MSVC inlines templates aggressively. This makes the solution I describe above untenable for dlls. Does Gcc never inline header-only templates like the std library as MSVC does? If so wouldn't that make the functionality of ELF described above ineffective in these cases?

  • Agile Documentation

    - by Nick Harrison
    We all know that one of the premises of the agile manifesto is to value Working Software over Comprehensive Documentation. This is a wonderful idea and it takes a tremendous burden off of project implementations. I have seen as many projects fail because of the maintenance weight of the project documentations as I have for any reason. But this goal as important as it is may not always be practical. Sometimes the client will simply insist on tedious documentation despite the arguments against it. This may be to calm a nervous client. This may be to satisfy an audit / compliance requirement. This may be a non-too subtle attempt at sabotaging the project. Ok, it is probably not an all out attempt to sabotage the project, but it will probably feel that way. So what can we do to keep to the spirit of the Agile Manifesto but still meet the needs of the client wanting the documentation? This is a good question that I have been puzzling over lately! I hope to explore some possible answers more fully here. A common theme that my solutions are likely to follow is the same theme that I often follow with simplifying complex business logic. Make it table driven! My thought is that the sought after documentation could be a report or reports out of a metadata repository. Reports are much easier to maintain than hand written documentation. Here are a few additional advantages that we can explore over time: Reports will take advantage of the fact that different people have different needs and different format requirements Reports and the supporting metadata are more easily validated and the validation can be automated. If the application itself uses this metadata than there never has to be a question as to whether or not the metadata is up to date. It is up to date or the application would not work. In many cases we should be able to automatically gather most of the Meta data that we need using reflection, system tables, etc. I think that this will lower the total cost of ownership for the documentation and may provide something useful beyond having a pretty document to look at.  What are your thoughts?

  • How to protect own software from copying [closed]

    - by Zzz
    Possible Duplicate: How do you prevent the piracy of your software? Is possible to protect some file from copying if you are administrator of machine? I heard some story about some behavior: one software developer sells his software in some way. He is installing it on every client's computer and this software does not work on other computers or cannot be copied physically. How to implement the first and second protection. Is it effectively protection if software costs about $100 for all copies across client's company?
