  • How to research unmanaged memory leaks in .NET?

    - by Brandon
    I have a WCF service running over MSMQ. Memory gradually increases over time, indicating that there is some sort of memory leak. I ran the service locally and monitored some counters using PerfMon. Total CLR memory managed heap bytes remains relatively constant, while the process' private bytes increases over time. This leads me to believe that there is some sort of unmanaged memory leak. Assuming that unmanaged memory leak is the issue, how do I address the issue? Are there any tools I could use to give me hints as to what is causing the unmanaged memory leak? Also, all my service is doing is reading from the transactional queue and writing to a database, all as part of a DTC transaction (handled under the hood by requiring a transaction on the service contract). I am not doing anything explicitly with COM or DllImports. Thanks in advance!

  • Tools and environments supporting Domain Driven Design (DDD)

    - by anthares
    Hi everyone, I'm doing a kind of research on the topic "Domain Driven Design". My question is what tools (or maybe environments) do you use, that support this paradigm? I know that I can google it, but I wonder which of them actually work and are useful, since I have no experience with neither of them. I'm interesting mainly in the .NET Framework, but any other opinions are also welcome! Thanks !

  • The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

    - by Hunter2
    Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

  • What's the best C# recommendation engine or framework?

    - by cDima
    Is there anyway to use the examples for the "My Media" Microsoft research project? My Media is a "dynamic personalization and recommendation software framework toolkit" ( http://www.mymediaproject.org ), but out of the box it doesn't provide a sample database (only a LINQ-to-SQL .dbml schema), I don't believe it will be easy to re-create by hand. I was hoping to understand recommendation engines and machine learning with this C#/.Net as a testbed, but without a simple quick start or db it seems impractical. Any suggestions? (I guess it's time to switch to Java with Apache's Mahout, Weka or something similar?)

  • Cost effective online consumer surveys / panels?

    - by Ed
    I am building a Windows based software targeted at consumers, and while I think it's awesome, I'm not sure if my potential customers will. I would like to do some market research to make sure I'm on the right track with the feature set. Unfortunately, I don't have the budget for a large sample size. I understand that I won't be able to get anything near statistical significance on the cheap, but some feedback is better than no feedback I figure. Are there any inexpensive resources for surveying a panel of 100-200 consumers? Thanks!

  • CS Education, where was it? Where is it now? Where is it going?

    - by CheesePls
    I'm planning on doing research into Computer Science education for my senior project and I could think of no better group of people to consult than the SO community. So, what do you think about the state of CS education in the United States (and the rest of the world, though I had planned on focusing on the US)? What do you feel are necessary topics? What topics are superfluous? Objects first vs. Objects early vs. Objects later? ALSO, if anyone has or knows of any blogs, studies, etc., those would be very helpful as well.

  • What is the best programming paper you have read?

    - by SDReyes
    I think that papers are a great information source. they generally tend to be built upon other experts investigations, and generally are short enough to transmit you great ideas in a short coffee read. But I don't really have read many papers in this area. So I would like to start soon and I'll be glad to hear your thoughts. So I wonder what have been the best programming paper you have read?

  • What to see in India as a developer and student

    - by lasseespeholt
    Hi, I'm planning a trip to India around July-August. And I want to hear Indian developers or developers traveled to India if there are something interesting to see in India (around Bombay) for developers in general. Maybe a conference etc. I have looked at http://www.conferencealerts.com/computing.htm I have studied computer science in a year now but have been a spare time and independent developer for some years now. Furthermore, I have tried finding summer courses but that is properly too late now and computer science summer courses is hard to find in India. Best regards, Lasse Espeholt

  • looking to streamline my RSS feed mashup

    - by Mark Cejas
    Hello crafty developers, I have aggregated RSS feeds from various sources with RSSowl, fetching directly from the social mention API. The RSS feeds are categorized into the following major categories: blogs, news, twitter, Q&A and social networking sites. Each major category is nested with a common group of RSS feeds that represent a particular client/brand ontology. Merging these feeds into the RSSowl reader application, allows me to conduct and save refined search queries (from the aggregated data) into a single file - that I can then tag and further segment for analysis. This scheme is utilized for my own research needs and has helped me considerably. However, I find this RSS mashup scheme kinda clumsy, it requires quite a bit of time to initially organize all of the feeds and I would like to be able to do further natural language processing to the data as well as eventually be able to rank the collected list of URL's into some order of media prominence - right I don't want to pay the ridiculous radian6 web analytics fees, when my intuition is telling me that with a bit of 'elbow grease' I can maybe leverage some available resources online to develop a functional low scale web mining application and get some good intelligence from it. I am now starting to learn a little about computer science - my background is in physical science/statistics so is my thinking in the right track? So, I guess I am imagining an application that allows me to query in a refined manner. A manner that allows me to search for keyword combinations, applying AND/OR operators, selectively focus my queries into particular sources - like a collection of blogs or twitter, or social networking communities, then save the results of my queries into a structured format that can then be manipulated and explored. Am I dreaming? I just had to get all of this out. any bit of advice and insight would be hugely appreciated. my best, Mark

  • Open-sourcing a web site with active users?

    - by Lars Yencken
    I currently run several research-related web-sites with active users, and these sites use some personally identifying information about these users (their email address, IP address, and query history). Ideally I'd release the code to these sites as open source, so that other people could easily run similar sites, and more importantly scrutinise and replicate my work, but I haven't been comfortable doing so, since I'm unsure of the security implications. For example, I wouldn't want my users' details to be accessed or distributed by a third party who found some flaw in my site, something which might be easy to do with full source access. I've tried going half-way by refactoring the (Django) site into more independent modules, and releasing those, but this is very time consuming, and in practice I've never gotten around to releasing enough that a third party can replicate the site(s) easily. I also feel that maybe I'm kidding myself, and that this process is really no different to releasing the full source. What would you recommend in cases like this? Would you open-source the site and take the risk? As an alternative, would you advertise the source as "available upon request" to other researchers, so that you at least know who has the code? Or would you just apologise to them and keep it closed in order to protect users?

  • When is Googling it wrong?

    - by Drahcir
    I've been going through Stack Overflow for quite a bit now and noticed certain people (usually experienced programmers) frown upon Googling (researching) certain problems. Since I myself tend to use Google quite a bit to solve certain programming related issues I found certain comments rather demoralising. Now some of you may have come here trigger happy to delete this post but I needed some clarification. I usually Google things that usually syntax related that I would have never figured out on my own. For example I once wondered how to access the properties of a class that I didn't have a direct relationship to. So after a bit of research I discovered reflection and got what I wanted. Now in another scenario is learning a new language, in my case Silverlight were it differs in certain aspects of .NET compared to say ASP.NET. A few weeks ago I had no idea how to load another Silverlight page (usercontrol) and had to Google my way to the solution which I found wasn't as simple as I had imagined. In scenario three is were I myself frown up, that is just stealing a huge chunk of code to avoid doing the work yourself, for example paging a HTML table using JavaScript, where one just copies and pastes the JavasSript code without as much as trying to understand how it works. I do admit I have done this once or twice before for trivial tasks that had very little time limit and weren't all that important but most of the time still have to throw away what I found because it took too much time to adapt it and get what I wanted out of it. In the last scenario, I sometimes have a piece of code that I would be really unhappy about, as in I find it sloppy or too overcomplicated and try to look on the Internet to see other ways to tackle the same problem, let's say filtering through a table. With the knowledge I acquire I learned new coding practices that help me work more efficiently like "Do not repeat yourself" and such. Now in your opinion when do you find it wrong to use Google (or any other researching tool) to find a solution to your problem?

  • Writing a report

    - by wvd
    Hello all, Since some time I've been investigating more time into profiling things better, really think about how to do a thing and why. Now I'm going to start a new project, where I will be writing a report about. The report will be about anything what I wrote in the project, why, and I'll be investigating some things and do particular research about them. I've seen some reports, such as game programming in Haskell using FRP. However, after reading several reports they all seem to be build different. I have a few questions about writing a report: 1] What are the things I really should include, and what are the things I really shouldn't include? 2] Is it useful to include graphs about different methods/approaches to a several problem, where you only included one into your project, to show WHY you didn't include the other methods. Or should I just explain the method/approach used into the project. 3] Should I only be writing the report after I've completed the project, or should I also write pages about what I expect, how I'm going to build the software? Thanks, William van Doorn

  • Is there any research about daily differences in productivity by the same programmer?

    - by Rice Flour Cookies
    There has been a flurry of activity on the internet discussing a huge difference between the productivity of the best programmers versus the productivity of the worst. Here's a typical Google result when researching this topic: http://www.devtopics.com/programmer-productivity-the-tenfinity-factor/ I've been wondering if there has been any research or serious discussion about differences in day-to-day productivity by the same programmer. I think that personally, there is a huge variance in how much I can get done on a day by day basis, so I was wondering if anyone else feels the same way or has done any research.

  • What are interesting research questions with regards to open source software development? [closed]

    - by Aron Lindberg
    Imagine you have funding for a team of social scientists to study open source software development for a number of years (long time in software development, I know, but a short time for scientific research). These scientists have competencies to investigate psychological and sociological aspects of open source software development (i.e. how coders think, feel, and behave, along with how communities work or do not work). They are also technically equipped to understand code and coding, have access to all sorts of statistical and machine learning techniques, however their focus is on social aspects of open source software development, not technical. For you, as an open source software developer, what would be the research questions that would be interesting for you to have answered by such a group of scientists?

  • As a self-taught programmer, how do I get the academic foundation without attending school again?

    - by hal10001
    I've made a pretty good living as a self-taught programmer, but when I find that I discuss some low-level fundamental topics with my peers who have a CS degree, holes appear in my knowledge. I'm a big picture (architecture) guy, so for a long time this hasn't bothered me, but lately I've wondered if there is an approach I can take that will help me learn these fundamentals without going back to school? Are there books, websites or videos that you can recommend that would give me a ground-up perspective as opposed to a learn it as you need it mentality?

  • Is there any research out there on geographic differences in work environments (e.g., respect) for programmers?

    - by Ethel Evans
    One thing I've learned from this website is that software developers are not treated the same as what I've seen in the companies I've worked at, and some of the differences seem to be related to the culture or other factors of the geographical location where the programmer works. In some areas, it seems like programmers can expect many perks and a great deal of professional respect, but in others it sounds like programmers are seen as laborers who are told what to do and then should go do it without question. Even in just the USA, there seem to be major differences in "the norm" between the various regions of this country. I'm wondering how much of this is just my perception, and how much is real differences about how programmers are perceived in their different locations. Is there any research out there discussing major differences in programmer work environments or attitudes about how to treat or respect programmers by geography? I'd be interested in multiple articles tackling different ways of looking at this. Edit: Research, specifically, doesn't seem to be available, so I'm making the question broader. Any good, thoughtful writing on the topic of any kind available?

  • Top-Rated JavaScript Blogs

    - by Andreas Grech
    I am currently trying to find some blogs that talk (almost solely) on the JavaScript Language, and this is due to the fact that most of the time, bloggers with real life experience at work or at home development can explain more clearly and concisely certain quirks and hidden features than most 'Official Language Specifications' Below find a list of blogs that are JavaScript based (will update the list as more answers flow in): DHTML Kitchen, by Garrett Smith Robert's Talk, by Robert Nyman EJohn, by John Resig (of jQuery) Crockford's JavaScript Page, by Douglas Crockford Dean.edwards.name, by Dean Edwards Ajaxian, by various (@Martin) The JavaScript Weblog, by various SitePoint's JavaScript and CSS Page, by various AjaxBlog, by various Eric Lippert's Blog, by Eric Lippert (talks about JScript and JScript.Net) Web Bug Track, by various (@scunliffe) The Strange Zen Of JavaScript , by Scott Andrew Alex Russell (of Dojo) (@Eran Galperin) Ariel Flesler (@Eran Galperin) Nihilogic, by Jacob Seidelin (@llimllib) Peter's Blog, by Peter Michaux (@Borgar) Flagrant Badassery, by Steve Levithan (@Borgar) ./with Imagination, by Dustin Diaz (@Borgar) HedgerWow (@Borgar) Dreaming in Javascript, by Nosredna spudly.shuoink.com, by Stephen Sorensen Yahoo!

  • 10 lines of code per day is the global average!? -- true?

    - by Earlz
    Ok so last year I participated in a high school curriculum contest thing at a college(I currently attend this college). I actually got 1st in it but was still a bit angry I didn't get every single one right. The most baffling of questions on there was How many lines of code does the average programmer write per day? A. 5 B. 10 C. 25 D. 30 Aside from being a subjective question which depended on language and everything else I was more baffled at what they had as the correct answer. 10. Even on my bad days at my job I touch more than 10 lines of code(either adding, modifying, or deleting) per day. And when I took this test I had only programmed as a hobby where it was common for me to write a few hundred lines for one of my new projects per day. Where are they getting this random number of ten!? Is this published somewhere? A quick googling found me nothing.
