• Using C# to make Application for Maemo (convert code to QT)

  - by blwthompson

  Hi, I want to make an application for my phone (Nokia N900) It uses the Maemo Platform, which is a Linux variant. Most applications are made with either QT or Python, i only have experience in C#, and am wondering if it is at all possible to convert C# to QT, or would i have to use something like Mono or Vala to write the code in C# and create the applications for the N900?? Cheers, Brendan

  - by maxfridbe

  This may seem like a stupid question, so here goes: Other than parsing the string of FileInfo.FullPath for the drive letter to then use DriveInfo("c") etc to see if there is enough space to write this file. Is there a way to get the drive letter from FileInfo?

• Can I point two separate ASP.NET websites to the same profile database?

  - by Ben Aston

  I'd like two websites to have read/write access to the same user profile database (named "aspnetdb" by default). Presumably this is possible by configuring the websites appropriately in the web.config. Are there any issues I should be wary of?

• Would a Centralized Blogging Service Work?

  - by viatropos

  If there's a better place to ask this, please let me know. Every time I build a new website/blog/shopping-cart/etc., I keep trying to do the following: Extract out common functionality into reusable code (Rubygems and jQuery plugins mostly) If possible, convert that gem into a small service so I never have to deal with a database for the objects involved (by service, I mean something lean and mean, usually built with the Sinatra Web Framework with a few core models. My assumption is, if I can remove dependencies on local databases, that will make it easier and more scalable in the long run (scalable in terms of reusability and manageability, not necessarily database/performance). I'm not sure if that's a good or bad assumption yet. What do you think? I've made this assumption because of the following reason: Most serious database/model functionality has been built on the internet somewhere. Just to name a few: Social Network API: Facebook Messaging API: Twitter Mailing API: Google Event API: Eventbrite Shopping API: Shopify Comment API: Disqus Form API: Wufoo Image API: Picasa Video API: Youtube ... Each of those things are fairly complicated to build from scratch and to make as optimized, simple, and easy to use as those companies have. So if I build an app that shows pictures (picasa) on an Event page (eventbrite), and you can see who joined the event (facebook events), and send them emails (google apps api), and have them fill out monthly surveys (wufoo), and watch a video when they're done (youtube), all integrated into a custom, easy to use website, and I can do that without ever creating a local database, is that a good thing? I ask because there's two things missing from the puzzle that keep forcing me to create that local database: Post API RESTful/Pretty Url API While there's plenty of Blogging systems and APIs for them, there is no one place where you can just write content and have it part of some massive thing. For every app, I have to use code for creating pretty/restful urls, and that saves posts. But it seems like that should be a service! Question is, is that the main point of a website? Will everyone always need "their own blog"? Why not just have a profile and write lots of content on an established platform like StackOverflow or Facebook?

• Gratuitous use of System.Runtime.Serialization attributes?

  - by rasx

  Is there any cost/drawback (apart from typing too much) to adorning a class with System.Runtime.Serialization attributes (like [DataContract]) such that it can be used locally as a direct reference to a desktop Client project or as a type for a WCF service? The goal here is to write a data-tier class that can be used in both rich client (WPF) and Web scenarios. My data classes will be in a project that is separate from Client and WCF (*.svc code-behind) code. Is this a valid attempt to reuse code?

• Automatically capitalize first letter of first word in a new sentence in LaTeX

  - by Tom Hagen

  I know one of LaTeX's bragging points is that it doesn't have this Microsoftish behavior. Nevertheless, it's sometimes useful. LaTeX already adds an extra space after you type a (non-backslashed) period, so it should be possible to make it automatically capitalize the following letter as well. Is there an obvious way to write a macro that does this, or is there a LaTeX package that does it already?

• Swing verify code on event dispatch thread at runtime

  - by Jeff Storey

  Are there any libraries that instrument code to verify that methods called on swing components are called on the event dispatch thread? It probably wouldn't be too difficult to write some basic code for doing this, but I'm sure there are edge cases and whatnot that other people have handled. I'm looking for this at runtime though, not for unit tests. thanks, Jeff

• Is there a good Open Source, XSD based Web Editor?

  - by ashansky

  I'm looking for a good open source web editor that will take xsd (or some other standard XML) and from that generate web forms that will enable the end user to generate standard xml (without knowing anything about xml obliviously). I took a look at kupu, but there doesn't seem to be much documentation and the site appears to no longer exist. Is there anything out there that does this already. I could write something like this myself, but if there's something that out there that will save me some time that would be great. Thanks

• python webtest port configuration?

  - by MattM

  I am attempting to write some tests using webtest to test out my python GAE application. The problem I am running into is that the application is listening on port 8080 but I cannot configure webtest to hit that port. For example, I want to use app.get('/getreport') to hit http://localhost:8080/getreport. Obviously, it hits just thits http:// localhost/getreport. Is there a way to set up webtest to hit a particular port?

• How to implement Scrum?

  - by Kaan

  We're trying to switch to Scrum as our development process but we're not sure how to implement it in the best way possible. We also don't want to pay for expensive software tools until we get scrum working and get positive results. How can we implement scrum using a whiteboard without asking people to write down their time on the board and then also input into our own time tracking software? What kind of methodologies do you use?

• jquery - detect if selector returns null

  - by peirix

  What is the best way to detect if a jQuery-selector returns an empty object. If you do: alert($('#notAnElement')); you get [object Object], so the way I do it now is: alert($('#notAnElement').get(0)); which will write "undefined", and so you can do a check for that. But it seems very bad. What other way is there?

• Backslashes in gsub (escaping and backreferencing)

  - by polygenelubricants

  Consider the following snippet: puts 'hello'.gsub(/.+/, '\0 \\0 \\\0 \\\\0') This prints (as seen on ideone.com): hello hello \0 \0 This was very surprising, because I'd expect to see something like this instead: hello \0 \hello \\0 My argument is that \ is an escape character, so you write \\ to get a literal backslash, thus \\0 is a literal backslash \ followed by 0, etc. Obviously this is not how gsub is interpreting it, so can someone explain what's going on? And what do I have to do to get the replacement I want above?
