• What to do when you are a programmer and have a cold?

  - by Zak

  If you have a cold that isn't too bad, does it make sense to still go into the office and get some coding done? Assume a private office, no meetings for the day, and you have some documentation and coding tasks that need to get done. Also assume that you operate on a PTO system, where all days off are "vacation" or PTO. To clarify, should one just not code at all when under the weather? That's what I'm getting at. Will you just kick yourself in your own rear when you go back to deal with code you wrote when you are sick? What is the error defect rate of sick vs non-sick programming hours?

• MongoDB or CouchDB - fit for production?

  - by Alan

  I was wondering if anyone can tell me if MongoDB or CouchDB are ready for a production environment. I'm now looking at these storage solutions (I'm favouring MongoDB at the moment), however these projects are quite young and so I foresee that I'm going to have to work quite hard to convince my manager that we should adopt this new technology. What I'd like to know is: 1) Who is using MongoDB or CouchDB today in a production environment? 2) How are you using MongoDB/CouchDB? 3) What problems (if any) did you come across when you adopted this new storage mechanism (and how did you overcome them)? 4) How did you deal with any migration issues that you had to deal with? 5) Do you have any good/bad experiences with either of these solutions that you'd like to share? Thanks.

• Programming tutorials for people with zero experience

  - by www.aegisub.net

  A friend of mine is interested in learning how to program computers, but she knows nothing about programming. I suggested that Python might be a good language to start with, but after some googling, I couldn't find any tutorials that covered both programming and Python in an adequate way. I don't want her to go through the tiresome "learn algorithms in pseudocode first" routine. Instead, I'd like a tutorial that will explain the basic ideas while working towards a real goal, e.g. a very simple console game. Does anyone know of any such tutorials? Do you think that I'm mistaken in how I'm handling this? Is Python a bad choice? I know that something like C, C++ or Java won't work - too many details will be very counterproductive. On the other hand, I think that Lisp might be too mathematical and abstract. Python, on the other hand, will let her even do something like coding primitive graphical games in a short period of time.

• How to raise an error, if the parsed number of a C++ stdlib stream is immediatly followed by a non whitespace character?

  - by Micha Wiedenmann

  In the following example, I didn't expect, that 1.2345foo would be parsed. Since I am reading data files, it is probably better to raise an error and notify the user. Is peek() the correct thing to do here? #include <iostream> #include <sstream> int main() { std::stringstream in("1.2345foo"); double x; in >> x; if (in) { std::cout << "good\n"; } else { std::cout << "bad\n"; } } Output good

• Structuremap Configuration with generics

  - by DarthVader

  I have IRepository interface with which i want to use NHibernateRepository. How do i configure it with structure map? protected void ConfigureDependencies() { ObjectFactory.Initialize( x => { x.For<ILogger>().Use<Logger>(); x.For<IRepository<T>>().Use<NHibernateRepository<T>>(); } ); } I m getting an error on T. Another question I have is if it s OK to make an ApplicationContext static class, configure it with structure map and provide instances with it? I have read that static classes are bad, but I dont want to initialize the ApplicationContext class that I have the injections everywhere. What s the best practice for this? Thanks.

• ClearCase UCM Mainline Configuration Management Pattern Question

  - by cogmios

  A configuration management pattern question (using Rational ClearCase UCM) When I use the mainline approach I create new releases by: - create release 1 from mainline - on a certain moment baseline release 1, deliver release 1 to mainline - create release 2 from mainline - on a certain moment baseline release 2, deliver release 2 to mainline - create release 3 from mainline - etc... Works very nice because the pathname is /main/release 3/latest instead of /main/release 1/release 2/release 3/latest etc... However... when in release 1 are new elements that have to be propagated to later releases I can not use the mainline since the mainline is already on e.g. release 4. The only thing I can do is deliver/merge from release 1 directly to release 2. The bad thing is that the pathname then becomes /main/release 1/release 2/latest for that files (and possibly later releases). That is I think not in line with the mainline approach. What am I doing wrong?

• problem with HttpWebRequest.GetResponse perfomance in multithread applcation

  - by Nikita

  I have very bad perfomance of HttpWebRequest.GetResponse method when it is called from different thread for different URLs. For example if we have one thread and execute url1 it requires 3sec. If we ececute url1 and url2 in parallet it requires 10sec, first request ended after 8sec and second after 10sec. If we exutet 10 URLs url1, url2, ... url0 it requires 1min 4 sec!!! first request ended after 50 secs! I use GetResponse method. I tried te set DefaultConnectionLimit but it doesn't help. If use BeginGetRequest/EndGetResponse methods it works very fast but only if this methods called from one thread. If from different it is also very slowly. I need to execute Http requests from many threads at one time. ?an anyone ever encountered such a problem? Thank you for any suggestions.

• Editing a TreeView node doesn't change the TreeNode Key

  - by Blitzz

  I have a TreeView with user-editable nodes. I like to use the node caption as key to my tree node : + Root |+ Node1 ||- SubNode1 ||- SubNode2 |+ Node2 ||- SubNode3 ||- SubNode4 So I can reach a node like this: MyTreeView.Nodes["Root"].Nodes["Node2"].Nodes["SubNode3"] The problem is that, as I allow the user to rename any node, I would need also to change the key of my node in its parent in the AfterLabelEdit handler... which seems (logically) not to be done automatically. Unfortunately, Nodes["blabla"] is readonly, Nodes.Add(string Key, TreeNode Node) doesn't exist, and I can't find a way to do this without throwing (sooner or later) a bad exception. Any idea ?

• Lua: Random: Percentage

  - by jargl

  I'm creating a game and currently have to deal with some math.randomness. As I'm not that strong in Lua, how do you think Can you make an algorithm that uses math.random with a given percentage? I mean a function like this: function randomChance( chance ) -- Magic happens here -- Return either 0 or 1 based on the results of math.random end randomChance( 50 ) -- Like a 50-50 chance of "winning", should result in something like math.random( 1, 2 ) == 1 (?) randomChance(20) -- 20% chance to result in a 1 randomChance(0) -- Result always is 0 However I have no clue how to go on, and I completely suck at algorithms I hope you understood my bad explanation of what I'm trying to accomplish

• Prims vs Polys: what are the pros and cons of each?

  - by Richard Inglis

  I've noticed that most 3d gaming/rendering environments represent solids as a mesh of (usually triangular) 3d polygons. However some examples, such as Second Life, or PovRay use solids built from a set of 3d primitives (cube, sphere, cone, torus etc) on which various operations can be performed to create more complex shapes. So my question is: why choose one method over the other for representing 3d data? I can see there might be benefits for complex ray-tracing operations to be able to describe a surface as a single mathematical function (like PovRay does), but SL surely isn't attempting anything so ambitious with their rendering engine. Equally, I can imagine it might be more bandwidth-efficient to serve descriptions of generalised solids instead of arbitrary meshes, but is it really worth the downside that SL suffers from (ie modelling stuff is really hard, and usually the results are ugly) - was this just a bad decision made early in SL's development that they're now stuck with? Or is it an artefact of what's easiest to implement in OpenGL?

• Porting C++-code from Windows to Unix: systemcalls colliding with name of functions

  - by marvin2k

  Hi I'm porting some crufty C++ Windows-code to Linux, which uses functions called "open" and "close" inside every class... Very bad style, or? Luckily that wasn't a problem in windows, since their systemcalls are named different. When I try to call the systemcalls open() or close() I'm getting some compiler error about "no matching function for call for class:open()". I can't rename all our functions named "class::open" and "class::close" in the whole code, and I have to use open() and close() since I'm working with serial ports. So my question is: How can I tell the compiler, which open I mean? How can I escape or hide the namespace of a class in C++?

• learning and "singing" Ruby with Sinatra

  - by microspino

  Hello I'm trying to improve my ruby knowledge by reading The Ruby Programming Language book. Reading Coders at work I saw that lot of the interviewees suggest to dive into a project source code to learn best practices to be aware of bad habits and of course to take new inspirations for how to do things. I decided to pick a project as more self contained as I could find. My choice was Sinatra since It's 1000 LOC. Is It a good project to learn? Do you suggest another one more simple (i.e. less LOCs)? I've tried to see rails machinery before but I came out scared from It.

• Have to put files in static_dir but need to read them afterwards

  - by SanjamX

  I just started using google app engine. In order to use templates, I'm using jinja2. I want to add images dynamically after I set the width and height of the img tag. I used PIL in order to read the image size and put the one I want. However when I open the image with PIL, I need it not to be in a static_dir and to put the image in the img tag, I need it to be in the static_dir. As a testing solution I've copied the folder to see if I get results and I did. But as you can see having each image saved twice is kind of bad.

• What performance indicators can I use to convince management that I need my development PC upgraded?

  - by Aaron Daniels

  At work, my PC is slow. I feel that I can be way more productive if I just wasn't waiting for Visual Studio and everything else to respond. My PC isn't bad (dual-core, 3GB of RAM), but there is a lot of corporate software and whatnot to slow everything down and sometimes lock it up. Now, some developers have begun getting Windows 7 machines with 8 GB of RAM. Of course, I start salivating at this. However, I was told that I "had to justify" why I should get a new machine. I can think of a lot of different things, but I am curious as to what every one else on SO would have to say. NOTE: Ideally, these reasons should be specifically related to .NET development in Visual Studio on a Windows machine. This isn't a "how can I make my machine faster" question.

• SharePoint SLK and T-SQL xp_cmdshell safety

  - by Mitchell Skurnik

  I am looking into a TSQL command called "xp_cmdshell" to use to monitor a change to a the SLK (SharePoint Learning Kit) database and then execute a batch or PowerShell script that will trigger some events that I need. (It is bad practice to modify SharePoint's database directly, so I will be using its API) I have been reading on various blogs and MSDN that there are some security concerns with this approach. The sites suggest that you limit security so the command can be executed by only a specific user role. What other tips/suggestions would you recommend with using "xp_cmdshell"? Or should I go about this another way and create a script or console application that constantly checks if a change has been made? I am running Server 2008 with SQL 2008.

• Noob here, but wanting to try and make my own app.

  - by Justin

  Hi all, I have a small amount of programing experience with Siemens and Allen Bradley but would like to make my own app for a certain website I frequent. I would like the website to be a little more user friendly for me instead of having to open browser etc. Is it possible to have a simple forum translated into a widget so you can see the forum posts and post from there? The website in question is http://vnboards.ign.com Any ideas or suggestions no matter how bad are appreciated. If it isnt worth attempting or my skills may not be up to par, feel free to say so :P Dont pull any punches :) Thanks! Justin

• How easy would it be to refactor a small JSP/Servlet/JDBC project to SpringMVC/Hibernate

  - by John

  With reference to this post, I am considering starting a new web-based Java project. Since I don't know Spring/Hibernate I was concerned if it's a bad plan to start learning them while creating a new project, especially since it will slow down the early development. One idea I had was to write a prototype using tech I do know, namely JSP/Servlets/JDBC, since I can get this running much quicker with my current knowledge. I could then throw the whole thing away and start over with Spring, etc, but I'd like to consider how easy it would be to refactor a smallish project from JSP/Servlets/JDB to SpringMVC/Hibernate? My DB could of course be re-used but what about other code... would I expect to save most of it plugged into an MVC framework, or is the paradigm shift big enough this would cause more trouble than it avoids? Please use the other question for more general advice on choosing technologies

• Ofstream writes empty file on linux

  Hi, I have a program which writes its output using ofstream. Everything works perfectly fine on Windows when compiled with Visual Studio, but it only writes empty file on Linux when compiled with GCC. ofstream out(path_out_cstr, ofstream::out); if(out.bad()){ cout << "Could not write the file" << flush; } else{ cout << "writing"; out << "Content" << endl; if(out.fail()) cout << "writing failed"; out.flush(); out.close(); } The directory which is being writen into has 0777 privileges. Thanks for help

• Handling exceptions, is this a good way?

  - by Jorge Córdoba

  We're struggling with a policy to correctly handle exceptions in our application. Here's our goals for it (summarized): Handle only specific exceptions. Handle only exceptions that you can correct Log only once. We've come out with a solution that involves a generic Application Specific Exception and works like this in a piece of code: try { // Do whatever } catch(ArgumentNullException ane) { // Handle, optinally log and continue } catch(AppSpecificException) { // Rethrow, don't log, don't do anything else throw; } catch(Exception e) { // Log, encapsulate (so that it won't be logged again) and throw Logger.Log("Really bad thing", e.Message, e); throw new AppSpecificException(e) } All exception is logged and then turned to an AppSpecificException so that it won't be logged again. Eventually it will reach the last resort event handler that will deal with it if it has to. I don't have so much experience with exception handling patterns... Is this a good way to solve our goals? Has it any major drawbacks or big red warnings?

• Visual Studio Add-in Exec running Automatically

  - by NewProgrammer

  Hey guys, I have a dilemma that I am uncertain about, as I not sure if it's is exactly possible for a Visual Studio Add-in to run its code automatically. I need an add-in that can run passively, like a logger for Visual Studios. However, the Exec method that I know so far can only execute commandbar functionality, but I need the code to execute when the user right-clicks, or select a line of text. I was able to make an automatic logger if i put my code in the "querystatus", but that would be considered bad programming, and it does not log when I simply select a piece of text. Does anyone know how to make a passive or automatic running code in Visual Studios?

• typeof === "undefined" vs. != null

  - by Thor Thurn

  I often see JavaScript code which checks for undefined parameters etc. this way: if (typeof input !== "undefined") { // do stuff } This seems kind of wasteful, since it involves both a type lookup and a string comparison, not to mention its verbosity. It's needed because 'undefined' could be renamed, though. My question is: How is that code any better than this approach: if (input != null) { // do stuff } As far as I know, you can't redefine null, so it's not going to break unexpectedly. And, because of the type-coercion of the != operator, this checks for both undefined and null... which is often exactly what you want (e.g. for optional function parameters). Yet this form does not seem widespread, and it even causes JSLint to yell at you for using the evil != operator. Why is this considered bad style?

• Is there a good collection library for C-language?

  - by matti

  We have to maintain and even develop C-code of our legacy system. Is there good collection library that would support Java/C# (new versions) style collections. Hashtable, HashSet, etc. Of course without objects, but with structs. The HashTable key limitations to "strings" and ints is not a problem. It wouldn't be bad if it's free even for commercial use. I'm back to C from C# and I must say i'm depressed using our own libraries and the language in general. We're using VS2005 and MS C-compiler if that has nothing to do with anything. Thanks & BR -Matti
