• Symlink in windows XP

  - by willson

  Hi, there. The question is how to make the similar thing like symlink in windows like in *nix. It's really hard to write whole path to the file in console (even using [tab], it's not the way if you need to change language). Adding everything in PATH is tiring too. It'll be great to make a symlink running one command. Actually I'm looking for console app.

  - by panzerschreck

  Are there any guidelines when quoting estimates for projects/tasks involving TDD? For example, when compared to normal development of a task taking 1 day to complete, how much more should a TDD driven task take? 50% more time or 70% more time? Are there any statistics available, assuming the developer is well versed with the language and the test framework?

  - by Calvin

  I'm looking for a language that will parse mathematical expressions for me pretty easily, but also be able to call functions and reference variables as needed. Jeval looks to be what I'm looking for, but unfortunately I'm working in C#. Is there a .Net based equivalent to jeval?

• Does the Dalvik file format (*.dx) support more instructions than a Java .class file?

  - by soc

  Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it? As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

• python: list manipulation

  - by Jason S

  I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

• domain name vs ip address, same server, but different speed

  - by bn

  I have two similar sites: - two of them have almost exactly the same codes, and running on the same server - both sites are the same, they just use different language. - database of the slower site is populated (maybe only the user table) the other tables for site content is the same - the faster uses root to access database one of the sites is not released yet, so it uses IP Address to access the site instead of domain name the site that is using IP address is faster (lot faster) the site that is using domain name is slower do you know why is this happening what could be the reason?

• Which IDE / code editor was the first to introduce a code completion feature?

  - by Uri

  I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

• Which conventions, events, etc. should I look into attending?

  - by perlox

  I am a student programmer and relatively new to the industry. Once I get out into the real world and have money to blow, which events/conventions/conferences/etc. should I look into attending? Which do you consider a must-attend-at-least-once-in-your-life-as-a-developer type of event? Just to clarify, any language, company, size, are acceptable. I'm mostly looking to generate a list of highly regarded conferences for a variety of different fields/interests.

• How do call this symbolic code transformation ?

  - by erric

  Hi, I often cross this kind of code transformation (or even mathematical transformation) (python example, but applies to any language) I've go a function def f(x): return x I use it into another one. def g(x): return f(x)*f(x) print g(2) leads to 4 But I want to remove the functional dependency, and I change the function g into def g(f): return f*f print g( f(2) ) leads to 4 too How do you call this kind of transformation, locally turning a function into a scalar ?

• communication foundation showing plain text / code behind

  - by Michel

  Hi, i have a wcf service which runs perfectly on my dev machine (vs2010, target 3.5) but once deployed, it shows me the code behind of the service (actually the plain text of the .svc file) and not the normal service page: <%@ ServiceHost Language="C#" Debug="true" Service="SilverlightPoc.Web.FinanceData" CodeBehind="FinanceData.svc.cs" %> Anyone any idea why the .svc file is rendered as plain text and not as wcf service?
