  • .NET developer needs FoxPro advice

    - by katit
    We have a prospect with FoxPro 2.6 (whatever it means) system. Our product integrates with other systems by the means of triggers (usually). We would place couple of triggers on X system and then just pull collected data for our use. This way there is no need to customize customers product and it works great(almost real time - we poll for changes every 30 seconds). Question: Can I put triggers on FoxPro 2.6? Can access FoxPro from .NET? Any catches/caveats?

  • How do you dive into large code bases?

    - by miku
    What tools and techniques do you use for exploring and learning an unknown code base? I am thinking of tools like grep, ctags, unit-tests, functional test, class-diagram generators, call graphs, code metrics like sloccount and so on. I'd be interested in your experiences, the helpers you used or wrote yourself and the size of the codebase, with which you worked with. I realize, that this is also a process (happening over time) and that learning can mean "can give a ten minute intro" to "can refactor and shrink this to 30% of the size". Let's leave that open for now.

  • Haskell: Best tools to validate textual input?

    - by Ana
    In Haskell, there are a few different options to "parsing text". I know of Alex & Happy, Parsec and Attoparsec. Probably some others. I'd like to put together a library where the user can input pieces of a URL (scheme e.g. HTTP, hostname, username, port, path, query, etc.) I'd like to validate the pieces according to the ABNF specified in RFC 3986. In other words, I'd like to put together a set of functions such as: validateScheme :: String -> Bool validateUsername :: String -> Bool validatePassword :: String -> Bool validateAuthority :: String -> Bool validatePath :: String -> Bool validateQuery :: String -> Bool What is the most appropriate tool to use to write these functions? Alex's regexps is very concise, but it's a tokenizer and doesn't straightforwardly allow you to parse using specific rules, so it's not quite what I'm looking for, but perhaps it can be wrangled into doing this easily. I've written Parsec code that does some of the above, but it looks very different from the original ABNF and unnecessarily long. So, there must be an easier and/or more appropriate way. Recommendations?

  • What tools to use for efficient link building?

    - by Evgeny
    As most SEO experts keep saying, it is not just the content that you have - but also a hefty amount of quality incoming links to your content that is important -- these are the two ways to get to the top of the search results. The question is where do I find the incomnig links? One way I know is Google Blog Search, it can be used to find blogs with related information to your content and some allow to leave comments. The comments usually consist of your name, e-mail and website. If you put your keyword instead of your name, then the keyword turns into a link to your website. Unfortunately most blogs put rel=nofollow on such links, but some blogs don't do that. What other ways are there to find quality pages to put keywords links back to your website? Quality link usually means: located on a page with relevant content does not have a rel=nofollow in the <a has a relevant keyword as in <a href=websitekeyword</a the page with the link has high PageRank (3+) and TrustRank

    - by pinaldave
    Is SQL boring? Not at all. SQL is fun – one has to know how to maximize the fun while working with SQL Server. Earlier I was invited to participate in the video Pluralsight. I am sure all of you know that I have authored 3 SQL Server Learning courses with Pluralsight – 1) SQL Server Q and A 2) SQL Server Performance Tuning and 3) SQL Server Indexing. Before I say anything I suggest all of you watch the following video. Make sure that you pay special attention after 0 minute and 36 seconds. What I can say about this. I am just fortunate to be part of the history in the making. There are more than 53 super cool celebrities in this video. In this just over 3 minute video there are so many story lines. I must congratulate director Megan and creative assistant Mari for excellent work. There are so many fun moments in this small video. Let me list my top five moments. @John_Papa ‘s dance at second 14 @julielerman playing with cute doggy The RACE between @josepheames and @bruthafish – the end is hilarious The black belt moment by @boedie @stwool relaxing on something strange! Well, this is indeed a great short film. This video demonstrates how cool is the culture of Pluralsight and how fun loving they are. A good organization provides an environment to its employees and partners to have maximum fun while they all become part of the success story. Hats off to Aaron Skonnard for producing this fun loving video. Well, after listening to this song for multiple times, I decided to give a call to Pluralsight. If you want, you can call them at +1 (801) 784-9032 or send an email to james-cole at pluralsight.com . What are your top five favorite moments?

  • Server Side Developer Prerequisites

    - by Jking
    I am new to server side development and am currently learning node.js. What sort of networking information should I be familiar with to allow for a smooth learning curve with server side development. Could anyone provide resources pertaining to the information required to get into server programming? To give you a better idea of my standpoint: I do not know how a server interacts with a database [Q: How does a NoSQL database, or database in general, communicate with a server?] I am unsure of how a web stack works [Q: I have heard of LAMP but do not know how Apache, MySQL, and PHP interact. Hopefully this applies to other stacks as well. How do the components of a stack work together? Also, is a MEAN stack an alternative, or is it completely irrelevant to this] I have trivial knowledge of internet protocol [however extremely inefficient][Q: What resources are beneficial when learning about networking, and how much/what knowledge should I acquire to program on the server side] I am unsure of what I am unsure of concerning networking information necessary to start development Information on how the client-server model works would be greatly appreciated

  • What makes a good developer / system documentation?

    - by deamon
    Much time is wasted to get new developers started with existing software systems, because there is no good documenation. But what makes a system documentation good? One thing is a good API documentation like the Java API doc, but how to transfer the "bigger picture" and other things that cannot be placed in the API doc? One constraint is that it should not be to hard and time consuming to write the docs, because that is one reason why it is omitted so often. So, what makes documentation good?

  • Lessons Building KeyRef (a .NET developer learning Rails)

    - by Liam McLennan
    Just because I like to build things, and I like to learn, I have been working on a keyboard shortcut reference site. I am using this as an opportunity to improve my ruby and rails skills. The first few days were frustrating. Perhaps the learning curve of all the fun new toys was a bit excessive. Finally tonight things have really started to come together. I still don’t understand the rails built-in testing support but I will get there. Interesting Things I Learned Tonight RubyMine IDE Tonight I switched to RubyMine instead of my usual Notepad++. I suspect RubyMine is a powerful tool if you know how to use it – but I don’t. At the moment it gives me errors about some gems not being activated. This is another one of those things that I will get to. I have also noticed that the editor functions significantly differently to the editors I am used to. For example, in visual studio and notepad++ if you place the cursor at the start of a line and press left arrow the cursor is sent to the end of the previous line. In RubyMine nothing happens. Haml Haml is my favourite view engine. For my .NET work I have been using its non-union Mexican CLR equivalent – nHaml. Multiple CSS Classes To define a div with more than one css class haml lets you chain them together with a ‘.’, such as: .span-6.search_result contents of the div go here Indent Consistency I also learnt tonight that both haml and nhaml complain if you are not consistent about indenting. As a consequence of the move from notepad++ to RubyMine my haml views ended up with some tab indenting and some space indenting. For the view to render all of the indents within a view must be consistent. Sorting Arrays I guessed that ruby would be able to sort an array alphabetically by a property of the elements so my first attempt was: Application.all.sort {|app| app.name} which does not work. You have to supply a comparer (much like .NET). The correct sort is: Application.all.sort {|a,b| a.name.downcase <=> b.name.downcase} MongoMapper Find by Id Since document databases are just fancy key-value stores it is essential to be able to easily search for a document by its id. This functionality is so intrinsic that it seems that the MongoMapper author did not bother to document it. To search by id simply pass the id to the find method: Application.find(‘4c19e8facfbfb01794000002’) Rails And CoffeeScript I am a big fan of CoffeeScript so integrating it into this application is high on my priorities. My first thought was to copy Dr Nic’s strategy. Unfortunately, I did not get past step 1. Install Node.js. I am doing my development on Windows and node is unix only. I looked around for a solution but eventually had to concede defeat… for now. Quicksearch The front page of the application I am building displays a list of applications. When the user types in the search box I want to reduce the list of applications to match their search. A quick googlebing turned up quicksearch, a jquery plugin. You simply tell quicksearch where to get its input (the search textbox) and the list of items to filter (the divs containing the names of applications) and it just works. Here is the code: $('#app_search').quicksearch('.search_result'); Summary I have had a productive evening. The app now displays a list of applications, allows them to be sorted and links through to an application page when an application is selected. Next on the list is to display the set of keyboard shortcuts for an application.

  • Configuration tools for multiple monitors for X / Linux

    - by richard
    I have Ubuntu 10.04 running gnome and two monitors. I am wondering if a can get a better multi-monitor configuration tool. The one I have, gnome-display-properties, has too many problems, including: When I swapped my monitors over, the narrower (external) one now on the left. There is a width calculation error, such that I have a virtual monitor the width of the wide-monitor on the narrow-monitor and part of the wide monitor. And a virtual narrow-monitor on the remainder of the wide-monitor. Also the visible mouse pointer does is not aligned with the active spot, an x offset of one monitor width. I would like, in approximate order of importance: nobugs. to be able to select which is primary monitor. to have multiple configurations. configurations to be automatically selected based on which monitors are attached. configurations to be cycled (reliably) when display mode key is pressed. when a display is deactivated, for windows to migrate to remaining monitors. option to not change display resolution when mirroring, but to use side/top blanking bars to pad out screen.
