  • What is the best keyboard/mouse for ergonomics or to prevent wrist pain?

    - by Steve Duitsman
    I have had pain in my wrists in the past, and as someone who types all day, I was wondering what are some keyboards or mice that have helped for this sort of pain. Update: Many answers have recommended examining chairs/desks for ergonomics. As someone who isn't able to work from home and therefore doesn't have a lot of control over this; is ordering my own chair/desk (whether my employer or I purchase it) a solution that's really realistic?

  • C99 and floating point environment

    - by yCalleecharan
    Hi, I was looking at new features of C99 and saw the floating point environment: #include <fenv.h> My question is simple. If I'm performing floating point number computations, do I have to include the above preprocessor directive in my code? If no, then what does this directive do and when does it become important to include? Thanks a lot...

  • Http Modules are called on every request when using mvc/routing module

    - by MartinF
    I am developing a http module that hooks into the FormsAuthentication Module through the Authenticate event. While debugging i noticed that the module (and all other modules registered) gets hit every single time the client requests a resource (also when it requests images, stylesheets, javascript files (etc.)). This happens both when running on a IIS 7 server in integrated pipeline mode, and debugging through the webdev server (in non- integrated pipeline mode) As i am developing a website with a lot images which usually wont be cached by the client browser it will hit the modules a lot of unnessecary times. I am using MVC and its routing mechanishm (System.Web.Routing.UrlRoutingModule). When creating a new website the runAllManagedModulesForAllRequests attribute for the IIS 7 (system.webServer) section is per default set to true in the web.config, which as the name indicates make it call all modules for every single request. If i set the runAllManagedModulesForAllRequests attribute to false, no modules will get called. It seems that the reason for this is because of the routing module or mvc (dont know excactly why), which causes that the asp.net (aspx) handler never gets called and therefore the events and the modules never gets called (one time only like supposed). I tested this by trying to call "mydomain.com/Default.aspx" instead of just "mydomain.com/" and correctly it calls the modules only once like it is supposed. How do i fix this so it only calls the modules once when the page is requested and not also when all other resources are requested ? Is there some way i can register that all requests should fire the asp.net (aspx) handler, except requests for specific filetype extensions ? Of course that wont fix the problem if i choose to go with urls like /content/images/myimage123 for the images (without the extension). But i cant think of any other way to fix it. Is there a better way to solve this problem ? I have tried to set up an ignoreRoute like this routes.IgnoreRoute("content/{*pathInfo}"); where the content folder contains all the images, javascripts and stylesheets in seperat subfolders, but it doesnt seem to change anything. I can see there a many different possibilites when setting up a handler but I cant seem to figure out how it should be possible to setup one that will make it possible to use the routing module and have urls like /blog/post123 and not call the modules when requesting images, javascripts and stylesheets (etc.). Hope anyone out there can help me ? Martin

  • Django Python Macports

    - by MacPython
    I installed Django via Macports. I wasted a lot of time on making it work. It still does not work. I would like to COMPLETELY uninstall Django (Macports) and install with the easy install (DJANGO). I would like to keep Macports and not uninstall it, because I read it SHOULD be useful. How can I achieve this? Thank you for your attention.

  • Personal Project - Next practical language/tech to learn

    - by Paul Nathan
    I'm working on a personal project doing some finance analysis. It's a totally new field for me, and I'm really having fun with it so far, plus working in the high-level language arena is a great break from my embedded systems daytime work. I have a MySQL backend on a non-local server with a pile of stock data. My task now is to do some analysis of the stocks and produce something approximating a useful result. There are a couple technical difficulties. (1) I have a lot of records. To be precise, I believe I'm near 100K records right now, and this number grows by 6.1K each weekday. I need to create a way to rummage through these fields and do data analysis - based on a given computation, go look at this other set. Fine and dandy, nothing too outre. But this means I could really use a straightforward API for talking to MySQL. (2) Ideally, it runs on OS X 10.4.11. No Windows/Linux machine at home. (3) I can use PHP, C++, Perl, etc. I even have an R installation. I'm pretty flexible with stuff, so long as it runs on OS X. (Lots of options here, pick water, H20, or dihydrogen monoxide ;-) ) (4)Lack of hassle. While I like clever and fun ways of doing things, I'm trying to get some analysis done, not spend ten hours doing installation work and scratching my head figuring out a theoretical syntax question needed to spout out "hello world". What's the question? I'd like to dig into something different than my usual PHP/C++/C toolset. I'm looking for recommendations for languages/technologies that will assist me and meet the above requirements. In particular, I've heard a lot of buzz about F# and Python on SO. I've used CLISP for small problems before, and kinda liked it. I'm seeking opinions about those in particular. edit:since I rent the DB server and have a limited amount of CPU time online, I'm trying to do the analysis on a local machine.

  • "Wrapping" a BindingList<T> propertry with a List<T> property for serialization.

    - by Eric
    I'm writing an app that allows users search and browse catalogs of widgets. My WidgetCatalog class is serialized and deserialized to and from XML files using DataContractSerializer. My app is working now but I think I can make the code a lot more efficient if I started taking advantage of data binding rather then doing everything manually. Here's a stripped down version of my current WidgetCatalog class. [DataContract(Name = "WidgetCatalog")] class WidgetCatalog { [DataContract(Name = "Name")] public string Name { get; set; } [DataContract(Name = "Widgets")] public List<Widget> Widgets { get; set; } } I had to write a lot of extra code to keep my UI in sync when widgets are added or removed from a catalog, or their internal properties change. I'm pretty inexperienced with data-binding, but I think I want a BindingList<Widget> rather than a plain old List<Widget>. Is this right? In the past when I had similar needs I found that BindingList<T> does not serialize very well. Or at least the Event Handers between the items and the list are not serialized. I was using XmlSerializer though, and DataContractSerializer may work better. So I'm thinking of doing something like the code below. [DataContract(Name = "WidgetCatalog")] class WidgetCatalog { [DataMember(Name = "Name")] public string Name { get; set; } [DataMember(Name = "Widgets")] private List<Widget> WidgetSerializationList { get { return this._widgetBindingList.ToList<Widget>(); } set { this._widgetBindingList = new BindingList<Widget>(value); } } //these do not get serialized private BindingList<Widget> _widgetBindingList; public BindingList<Widget> WidgetBindingList { get { return this._widgetBindingList; } } public WidgetCatalog() { this.WidgetSerializationList = new List<Widget>(); } } So I'm serializing a private List<Widget> property, but the GET and SET accessors of the property are reading from, and writing to theBindingList<Widget> property. Will this even work? It seems like there should be a better way to do this.

  • Using ASP.NET Automatically login to an external website and redirect

    - by DoodleWalker
    Hello, We have a series of products with built in web servers each of which has a login page, a customer wants to create a web portal in which they log into once, from there they can simply click on any of the devices (external websites) and it will automatically login to that site and redirect them to the page after the login screen. The portal is using ASP.NET MVC, the external devices are Windows CE based units running embedded web servers. Can find a lot on scraping, but not much on redirection after the event. Many Thanks Andy

  • Is it worth moving from stored procedures to linq ?

    - by Josef
    I'm looking at standardizing programming in an organisaiton. Half uses stored procedures and the other half Linq. From what i've read there is still some debate going on on this topic. My concern is that MS is trying to slip in it's own proprietry query language 'linq' to make SQL redundant. If a few years back microsoft had tried to win customers from oracle and sybase with their MSSQL database and stated that it didn't use SQL by their own proprietry query langues ie linq. I doubt many would have switched. I believe that is exactly what is happening now by introducting it into the applicaiton business layer. I have used MS for many years but there is one gripe that I have with them and that is that they change their direction a lot. By a lot I mean new releases of .net, silverlight etc are more than 30% different from previous version. So by the time you become productive a new release is on the way. As things stand now a web developer using .net would need to know either vb.net or c#, xml, xaml,javascript,html, sql and now linq. That doesn't make for good productivity in my books. My concern is that once we all start using linq MS will start changing it between releases. and it will become an ever changing landscape. I believe that 'linq to sql' has already been deprecated. At leas with SQL we are dealing with a more stable and standardized language. Are we looking at a programming revolution or a marketing campaign? As far as I know other languages like Cobol have stayed the same for years. A cobol program from 20 years ago could pick up todays code and start working on it. Could a Vb3 person work on a modern .net web app ? Would these large changes need to be made if the underlying original foundation had been sound ? I worry about following MS shaking roadmap with it's deadends and double backs. are there any architects out there who feel the same ? regards Josef
