• What are good example R packages written using runit or roxygen?

  - by PaulHurleyuk

  I'm writing an R package that's going to be used by others, so I'm trying to get this one right! I want to use roxygen for documentation and runit for unit testing, but I haven't used them before. What packages exist (either on CRAN or elsewhere) that use either of these tools well?

• Setting the AccountController in ASP.NET MVC 1.0 Template Not to Connect to SQL Server Express

  - by Maxim Z.

  I'm writing a website in ASP.NET MVC, using the ASP.NET MVC 1.0 template that was added to VS2008 for me by the ASP.NET MVC installer. The template automatically adds an AccountController, but its account methods tie into a SQL Server Express entity. I don't have Express installed here. How can I reconfigure it to use my SQL Server 2008 database and to store user info in some columns in a User table I've already created?

• Update saved password for basic authentication using a script

  - by Kalamane

  I have a website that uses basic authentication as described on this webpage. Each of the computers I manage have the password saved in their browser. There is only one username and password for this. After someone logs in to the site this way, they are presented with their individual username and password prompt as part of the web page. The purpose of the initial username/password is to discourage non-technical employees that aren't supposed to be using the page from even viewing it. So far, when we've had to change this password, I've manually gone to each computer and updated the saved password. I'm writing a startup script to configure other aspects of these systems so that I can maintain them easier. I'd like to be able to update the saved password via this script. The operating system running on these machines is Windows XP SP3 and the browsers they're using to access this site are IE8 and IE9. How can I update the saved basic authentication information for a website via a script?

• Display regular street map on Google Earth

• Android: Text primary key with different name

  - by Echilon

  I have an existing Windows app for which I'm writing an Android port. The app uses a unique string as the primary key, but the SQLite methods in Android all seem to work with integers and a column names _id, whereas my ID column isn't called this. Is there a way to let Android know I have a key with a different column name?

• Code indentation helper for gedit (python).

  - by aviraldg

  See the little vertical lines? They're damn helpful when writing Python code. Any chance I could get something similar for gedit? I wouldn't mind having to write my own plugin, as long as it's in Python... So: Is there a plugin for this in gedit? If not, would it be possible to write one in Python.

• De-normalization for the sake of reports - Good or Bad?

  - by Travis

  What are the pros/cons of de-normalizing an enterprise application database because it will make writing reports easier? Pro - designing reports in SSRS will probably be "easier" since no joins will be necessary. Con - developing/maintaining the app to handle de-normalized data will become more difficult due to duplication of data and synchronization. Others?

• Suppress the HTTP_X_FORWARDED_FOR http header, c# .net C++

  - by Sean

  I'm writing an application in C# that uses proxies. The proxies are sending the HTTP_X_FORWARDED_FOR during HTTP requests, and this is unwanted behavior. I am extending the Interop.SHDocVw axWebBrowser (aka Internet Explorer) control right now, but can take another approach if needed for this problem. Is there some way to suppress this header... can this be done in code, on the proxy server, or not at all?

  I am writing a program that generates excel reports, currently using the Microsoft.Interop.Excel reference. My dev computer has Excel on it, but the end user may or may not have Office installed.

• Get individual query parameters from Uri

  - by Ghostrider

  I have a uri string like: http://example.com/file?a=1&b=2&c=string%20param Is there an existing function that would convert query parameter string into a dictionary same way as ASP.NET Context.Request does it. I'm writing a console app and not a web-service so there is no Context.Request to parse the URL for me. I know that it's pretty easy to crack the query string myself but I'd rather use a FCL function is if exists.

Thanks!

• Connect through SSH and type in password automatically, without using a public key

  - by binary255

  A server allows SSH connections, but not using public key authentication. It's not within my power to change this at the moment (due to technical difficulties, not organizational) but I will get on it as soon as possible! What I need now is to execute commands on the server using plain old account+password authentication from a script. That is, I need to do it in a non-interactive way. Is it possible? And how do I do it? The client which will be executing the script runs Ubuntu Server 8.04. The server runs Cygwin and OpenSSH.

• How do I negotiate for colo space?

  - by randy melder

  I guess this isn't a technical question, but it definitely is something IT teams deal with, so here goes: I'm looking at getting a rack at a local colocation facility. I'm weighing the options versus building out in a cloud platform. We are REALLY low bandwidth and power. There's a total of six hosts for the total operation. You can assume we use <= 10 amps of power and <= 2Mbps 95th percentile. Do you have any advice for getting the best deal?

• Copy an entity in Google App Engine datastore in Python

  - by Gordon Worley

  In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in. How should I do this? In particular, are there any caveats or tricks I need to be aware of when doing this so that I get a copy of the sort I expect and not something else.

• How to write backwards compatible HTML5 ?

  - by Olivier Lalonde

  I'd like to start using HTML5's basic features, but at the same time, keep my code backwards compatible with older browsers (graceful degradation). For instance, I'd like to use the cool CSS3 properties for making rounded corners. Is there any available tutorial for writing gracefully degradable HTML5 ? Additionally, what browsers should I support so that my app. is functional for at least 95% of visitors? What are the ways to test those browsers painlessly ?

• How to Compute a Database Column in .NET

  - by Michael

  I have a Database named CarsType.accdb there are four fields in the data base Item_Name, Item_Num, Item_Qty, Item_Cost. I am able to get the database to display my data in VisualBasic but I am not sure how to get the total cost to appear in my label (lblTotalCost).
