  • What is the strangest/weirdest program you've ever made?

    - by MrValdez
    Programmers are strange people. We build things out of thin air, a part of our sanity and with weird codes that would make any grown sane man cry. But sometimes, a programmer builds a program that is too weird even by their insane standards. What program have you created that is weird and strange? (One program per answer please)

  • Is a degree in Industrial engineering helpful for programmers

    - by Shailesh Tainwala
    Hi, I am currently pursuing my MS in Software Engineering. I am considering the option of doing a part time programme in Industrial Engineering as most of the courses (Operations Research, Accountancy, Business Process etc) are those that I do not have any knowledge in. Is there a requirement in the industry for people with such qualifications? My long term career goal is to manage software projects that enable clients to increase productivity.

  • PHP: Does $_SERVER['HTTP_X_REQUESTED_WITH'] exist or not?

    - by Hank
    All over the Internet, included even here at StackOverlow, people state that a good way to check if a request is AJAX or not is to do the following: strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest' ) However, I don't see $_SERVER['HTTP_X_REQUESTED_WITH'] in the official PHP documentation And when I try to do the following: echo $_SERVER['HTTP_X_REQUESTED_WITH']; Nothing is outputted. Am I doing something wrong? Because I'd really like to be able to use $_SERVER['HTTP_X_REQUESTED_WITH'] if it's available.

  • When should I use git pull --rebase?

    - by Jason Baker
    I know of some people who use git pull --rebase by default and others who insist never to use it. I believe I understand the difference between merging and rebasing, but I'm trying to put this in the context of git pull. Is it just about not wanting to see lots of merge commit messages? Or are there other issues?

  • Subsonic Simple Repo for high volume site

    - by kjgilla
    Simple Repo has given me a competitive edge in my consulting. I can finish projects much faster than I could in the "cmd.Parameters.Add(param)" days. As things progress on this end im getting into higher volume sites and wondering if Simple Repo is still the way to go. Im wondering what people's experiences have been putting SR into production vs. NHibernate. Any tips or tricks for using SR in production.

  • Release Process Improvements

    - by wallismark
    The process of creating a new build and releasing it to production is a critical step in the SDLC but it is often left as an afterthought and varies greatly from one company to the next. I'm hoping people will share improvements they have made to this process in their organisation so we can all takes steps to 'reduce the pain'. So the question is, specify one painful/time consuming part of your release process and what did you do to improve it? My example: at a previous employer all developers made database changes on one common development database. Then when it came to release time, we used Redgate's SQL Compare to generate a huge script from the differences between the Dev and QA databases. This works reasonably well but the problems with this approach are:- ALL changes in the Dev database are included, some of which may still be 'works in progress'. Sometimes developers made conflicting changes (that were not noticed until the release was in production) It was a time consuming and manual process to create and validate the script (by validate I mean, try to weed out issues like problem 1 and 2). When there were problems with the script (eg the order in which things were run such as creating a record which relies on a foreign key record which is in the script but not yet run) it took time to 'tweak' it so it ran smoothly. It's not an ideal scenario for Continuous Integration. So the solution was:- Enforce a policy of all changes to the database must be scripted. A naming convention was important for ensuring the correct running order of the scripts. Create/Use a tool to run the scripts at release time. Developers had their own copy of the database do develop against (so there was no more 'stepping on each others toes') The next release after we started this process was much faster with fewer problems, indeed the only problems found were due to people 'breaking the rules', eg not creating a script. Once the issues with releasing to QA were fixed, when it came time to release to production it was very smooth. We applied a few other changes (like introducing CI) but this was the most significant, overall we reduced release time from around 3 hours down to a max of 10-15 minutes.

  • What is the general process of web hosting?

    - by ggfan
    I want to upload my site public so people can use it. I am currently using a free PHP webhosting company that supports up to a certian amount. When sites that say they offer unlimited upload, data, etc for like $10/month, is that all you need to run a big site? Or how do I host a big site, if it gets popular?

  • CSharp: Testing a Generic Class

    - by Jonas Gorauskas
    More than a question, per se, this is an attempt to compare notes with other people. I wrote a generic History class that emulates the functionality of a browser's history. I am trying to wrap my head around how far to go when writing unit tests for it. I am using NUnit. Please share your testing approaches below. The full code for the History class is here (http://pastebin.com/ZGKK2V84).

  • What makes Ometa special?

    - by Brian
    Ometa is "a new object-oriented language for pattern matching." I've encountered pattern matching in languages like Oz tools to parse grammars like Lexx/Yacc or Pyparsing before. Despite looking at example code, reading discussions, and talking to a friend, I still am not able to get a real understanding of what makes Ometa special (or at least, why some people think it is). Any explanation?

  • What is the exact problem with multiple inheritance?

    - by Totophil
    I can see people asking all the time whether multiple inheritance should be included into the next version of C# or Java and C++ folks, who are fortunate enough to have this ability, say that this is like giving someone a rope to eventually hang themselves. What’s the matter with the multiple inheritance? Are there any concrete samples?

  • Which are the good ASP.NET MVC 2 books?

    - by Dan Dumitru
    I'm sorry for asking yet another "best [insert-technology] book". I know a bit of MVC, I want to start a project in MVC 2 and a good book would be really helpful. Usually, after a while, people come to a consensus what are the top 2-3 books for learning a given technology. Have you read any ASP.NET MVC 2 book?

  • Storing third-party libraries in source control

    - by graham.reeds
    Should libraries that the application relies on be stored in source control? One part of me says it should and another part say's no. It feels wrong to add a 20mb library that dwarfs the entire app just because you rely on a couple of functions from it (albeit rather heavily). Should you just store the jar/dll or maybe even the distributed zip/tar of the project? What do other people do?

  • Volunteer for a potential employer?

    - by EoRaptor013
    I've been looking for work since March, and haven't had much luck. Recently, however, I interviewed with a small company near my home for a C#, .NET, SQL development position. I hit it off very well with the hiring manager during the phone screen, and even more so during the face to face. Unfortunately, I failed the practical test: wiring up a web form, creating a couple of SQL stored procedures, saving new data with validation, and creating a minimal search screen. I knew what I was doing, but I was too slow to meet their standards as all the work needed to be done within an hour. Nevertheless, I really liked the place, the environment, the people who I would have been working with, and the boss. (I gave the company an 11 on Joel's 12 point scale.) So, the obvious next step was to scrape the rust off. I've been trying to create little projects for myself, but I don't know that I've been effective in getting any faster. What with all that goes into creating a project, I'm not heads-down coding as much as I think I need. Now, with all that introduction, here's the question. I have been thinking about calling the hiring manager at that place, and asking him to let me volunteer for three or four weeks, with no strings attached. I think it would benefit me, and wouldn't cost him anything (as long as I didn't slow the existing people down!). At the end of that period, he might, or might not, be inclined to hire me, but even if not, I would have had as much as 160 hours of in the trenches development. Maybe not all shiny, but no more rust, I would think. Does this plan make any sense at all? I certainly don't want to sound desperate (although, I'm not far from being there), and I very much need the tuneup, lube, and change the oil. What's the downside, if any, to me doing this? Do any of you see red flags going up—either from the prerspective of the hiring manager, or from the perspective of a developer?

  • Going from a math career to a cs career: how to do it?

    - by Joseph
    Hey, I'm looking for some advice on how to successfully make the transition from mathematics to CS. My academic background is in mathematics (BS and MSc), and I've taken loads of math courses as well. You name it, and I took it: Measure Theory, Algebra, PDES, Manifolds, Complex Analysis, etc. I progressed quite far along this track, and at one point, I thought I would be a professional mathematician...But around the time I was finishing my MSc, I really got sick of it. Studying very abstract mathematics was fun, but it really lost it's appeal to me. Outside of a couple hundred people, I'm not sure if anybody would understand my research. I did not want to be 60 years old and say that my only contribution to the world consisted of published papers. Anyways, I've been an off and on hobbyist programmer since 2002. I've programmed in C and Java (just small projects), and I really started to be drawn to the area as time passed. There's a real appeal to CS work because, well, it actually means something to other people out there! I enjoy all parts of it: designing webpages (a real artistic appeal). On the other end, I do enjoy toying with compilers and more nitty-gritty stuff as well. Suffice to say, I have broad interests out there. Anyways, I know it's a bit late, but I was wondering if there were other folks out there who made the change, and if so, how I could do so. I know I have some fairly big gaps to fill in terms of data structures, lack of internship experience, etc. But I really would like to make this work. So my question is simply: How can I make the switch from math to CS? To pay the bills, I'll be doing financial analysis for a company, but I'd like to eventually transition into a developer type position. I've been reading "Algorithm Design" by Tardos and doing all the problems. It's not hard to make progress since the problems are far more concrete than the stuff I've been doing the past six years. I feel I can make fairly rapid progress in picking up all the materials from data structures, etc. but none of it can substitute the past several years I've lost. Anyways, I'm eager to learn but would love some advice/concrete direction. Thanks, Joseph

  • Perl vs Python: implementation of algorithms to deal with advanced data structures

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?
