• Sharepoint bug database - any good?

  - by jkohlhepp

  We've been using Sharepoint as a poor man's bug tracking database for the last couple of projects that we did. No one is really happy with the solution so I'm looking for alternatives. I happened to stumble upon the Bug Database Template for Sharepoint. If it is halfway decent it might be a good choice for us since the transition would be smooth as the team is already used to Sharepoint. Anyone have any experience using this template? Any major problems? Any major missing features? Is there any documentation out there beyond that download page? Thanks for the help.

• Good place to look for example Database Designs - Best practices

  - by Younes

  I have been given the task to design a database to store a lot of information for our company. Because the task is rather big and contains multiple modules where users should be able to do stuff, I'm worried about designing a good data model for this. I just don't want to end up with a badly designed database. I want to have some decent examples of database structures for contracts / billing / orders etc to combine those in one nice relational database. Are there any resources out there that can help me with some examples regarding this?

• What are some good web development blogs?

  - by Poita_

  I'm just getting into some basic web development (just a personal homepage for now, but I have plans for bigger things once I know the basics). I find that blogs can be quite helpful in getting into the mindset of a particular activity, so I was wondering if anyone knew some good ones. I'm particularly looking for education blogs i.e. ones that actually explain how to do things instead of just making commentary on them. If the blog is specific to LAMP, or any one (or more) of those things (Linux, Apache, MySQL, PHP) then that's a bonus. Thanks in advance.

• Good book for THINKING in terms of algorithms?

  - by chrisgoyal

  Before you mark this is a duplicate, let me explain why this is different. Most of the books on algorithms are more of a reference. You basically have a list of algorithms at your disposal. But what happens when you need to create a new algorithm for something? These books don't teach how to think in terms of algorithms. So I'm looking for books that will teach me the thinking-process of creating algorithms. Any good suggestions?

• Good examples of MVVM Template

  - by jwarzech

  I am currently working with the Microsoft MVVM template and find the lack of detailed examples frustrating. The included ContactBook example shows very little Command handling and the only other example I've found is from an MSDN Magazine article where the concepts are similar but uses a slightly different approach and still lack in any complexity. Are there any decent MVVM examples that at least show basic CRUD operations and dialog/content switching? Everyone's suggestions were really useful and I will start compiling a list of good resources Frameworks/Templates WPF Model-View-ViewModel Toolkit MVVM Light Toolkit Prism Caliburn Cinch Useful Articles Data Validation in .NET 3.5 Using a ViewModel to Provide Meaningful Validation Error Messages Action based ViewModel and Model validation Dialogs Command Bindings in MVVM More than just MVC for WPF MVVM + Mediator Example Application Additional Libraries WPF Disciples' improved Mediator Pattern implementation(I highly recommend this for applications that have more complex navigation)

• [hibernate - jpa ] good practices and bad practices

  - by blow

  Hi all, i have some questions about interaction with hibernate. openSession or getCurrentSession (without jta, thread insted)? How mix session operations with swing gui? Is good have something like this in a javabean class? public void actionPerformed(ActionEvent event) { // session code } Can i add methods to my entities that contains hql queries or is a bad practice? For example: // This method is in an entity MyOtherEntity.java class public int getDuration(){ Session session=HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); int sum=(Integer)session.createQuery("select sum(e.duration) as duration from MyEntity as e where e.myOtherEntity.id=:id group by e.name"). .setLong("id", getId()); .uniqueResult(); return sum; } In alternative how can i do this in a better and elegant way? Thanks.

• Good Silverlight Custom ItemsControl Tutorial

  - by Steve Brouillard

  I'm afraid my Google-Foo is failing me again today. I'm trying to find a good tutorial on creating custom ItemsControls in Silverlight (though I imgaine a WPF version might work as well). I'm trying to create a custom ItemsControl that will be something of a virtualized ListBox. What I'm trying to accomplish isn't really similar enough to the current ListBox control to justify trying to modify the existing control, so I figure a custom one is in order here. I have a vague concept of how to accomplish it, but there are definite holes in my understanding. Thanks in advance

• Good projects to learn OCaml and F#

  - by Yin Zhu

  After learning the basic syntax, reading some non-trivial code is a fast way to learn a language. We can also learn how to design a library/software during reading others' code. I have following lists. A Chess program in OCaml by Tomek Czajka. Hal Daumé has written several machine learning libraries in Ocaml. Including decision trees, logistic regression and SVM. All of them are near-production-quality code. A Chess Game Analysis program in F# in Microsoft Research. The above three are my favorites. Will you suggest some other sources? General purpose open source software are good, specialized open source like the three I list here are even more welcome.

• Recommend a good db4o viewer

  - by mgroves

  I'm playing around with db4o, and I have the Object Manager viewer thingy for Visual Studio. It seems okay, but not exactly on par with tools like HeidiSQL/SQL Studio/etc., not to mention that it locks the db4o file--I can't use my db4o app and Object Manager at the same time. Maybe I'm using it wrong, but regardless, I'd like to know what else is out there. What tools would you recommend for looking at and manipulating db4o files?

  - by reinhat

  Hi, The following page looks good in Firefox, Safari, Chrome, IE6 and IE8... but it looks bad in IE7. I don't have IE7 but I need to fix this issue because someone seen it in IE7 and it looks bad. Does anyone has any idea why this page renders different in IE7?...and what is the solution to make it display correctly? http://www.aetna.com/2009annualreport/mainBoard.html Problem: When you click on the "Board of Directors" or "Management Team" link and the listing table panel opens up, the far right third of the panel is getting cut off. Also some information appears to be missing in the cells. Thanks, Attila

• passing timezone from client (GWT) to server (Joda Time)

  - by Caffeine Coma

  I'm using GWT on the client (browser) and Joda Time on the server. I'd like to perform some DB lookups bounded by the day (i.e. 00:00:00 until 23:59:59) that a request comes in, with the time boundaries based on the user's (i.e. browser) timezone. So I have the GWT code do a new java.util.Date() to get the time of the request, and send that to the server. Then I use Joda Time like so: new DateTime(clientDate).toDateMidnight().toDateTime() The trouble of course is that toDateMidnight(), in the absence of a specified TimeZone, will use the system's (i.e. the server's) TimeZone. I've been trying to find a simple way to pass the TimeZone from the browser to the server without much luck. In GWT I can get the GMT offset with: DateTimeFormat.getFormat("Z").fmt(new Date()) which results in something like "-0400". But Joda Time's DateTimeZone.forID() wants strings formatted like "America/New_York", or an integer argument of hours and minutes. Of course I can parse "-0400" into -4 hours and 0 minutes, but I'm wondering if there is not a more straightforward way of doing this.

• Assert a good practice or not ?

  - by rkenshin

  Is it a good practice to use Assert for function parameters to enforce their validity. I was going through the source code of Spring Framework and I noticed that they use Assert.notNull a lot. Here's an example public static ParsedSql parseSqlStatement(String sql) { Assert.notNull(sql, "SQL must not be null");} Here's Another one public NamedParameterJdbcTemplate(DataSource dataSource) { Assert.notNull(dataSource, "The [dataSource] argument cannot be null."); this .classicJdbcTemplate = new JdbcTemplate(dataSource); } public NamedParameterJdbcTemplate(JdbcOperations classicJdbcTemplate) { Assert.notNull(classicJdbcTemplate, "JdbcTemplate must not be null"); this .classicJdbcTemplate = classicJdbcTemplate; } Thank you

• WYSIWYG browser editor that generates *good* HTML?

  - by dauerbaustelle

  I'm searching for a "suck less" WYSIWYG browser HTML editor that generates good HTML code. (no <font>, <foo style="...">, <p></p><span></span><p><span>&nbsp;</span><span><span>blah</span></<span></p> and so on -- <b> and <i> etc is ok). Should be easy-to-use as it is going to be used by people that do not know what HTML is. Any suggestions? (I found a lot of editors but they all create that <font> and nested <span> crap that breaks site design and bloats a site with one table up to 100kB.)

• Good embedded database solution (like SQLite) for .Net

  - by vfilby

  I am looking for file based storage solutions that I can use with a .Net project. THey need to have a sql-like interface for storing and retrieving data. They need to have relatively little overhead and must not require any additional components installed by the end user. I am hopping for a .dll that I can reference and use. Cool points awarded if it is closely tied to an ORM. My current favourite is SQLite, are there any better ones out there that I should know about? I have a (health?) bias against access because I feel it is overcomplicated for what I need, I am open to being convinced otherwise though. PS: "No, there is nothing better than SQLite" is a perfectly good answer.

• Which is a good opensource user management system?

  - by Lost_in_code

  I'm new to php/mySQL and am trying to create a website which will allow users to register. In future, there will be a paid content area where content will be shown based on the payment status. Is there a good opensource lightweight framework which takes care of the user management part? (Register, edit user info, retrieve lost password etc). I'm a flash platform developer and not aware of how to take care of stuff like session hijacking, XSS etc. Should I go ahead and learn to do all this on my own, without using any framework? I thought of using Wordpress' user management system, but not sure how easy that would be. Any suggestion would be great.

• Use the Twitter API to run a script every time I post a new tweet

  - by Mathias Bynens

  I have a PHP script on my server that I want to run every time I post a new tweet to Twitter. Is there a way to automate this? I could of course set up a cron job to run the script every five minutes, or run the script manually every time after tweeting, but neither of those is instant — and that’s exactly what I’m looking for. Is it possible to use the Twitter API to run a script / get a URL every time my timeline is updated?

• Trying to find a good strategy using Git for personal development on local/personal machine

  - by AJ

  A noob here. I have a personal Macbook and I want to use Git to track the changes etc. I want to just init a repo on my macbook and work there. Is this a good idea? What if: I have a main repo somewhere in my Macbook HD, like, /Users/user/projects/project1 and clone it to another area on my macbook where I actually perform development? But there is a lot of redundancy in this. I am a little confused and want to know what are the usual steps folks take in a similar personal development environment. Thanks a lot.

• Create ntp time stamp from gettimeofday

  - by krunk

  I need to calculate an ntp time stamp using gettimeofday. Below is how I've done it with comments on method. Look good to you guys? (minus error checking). Also, here's a codepad link. #include <unistd.h> #include <sys/time.h> const unsigned long EPOCH = 2208988800UL; // delta between epoch time and ntp time const double NTP_SCALE_FRAC = 4294967295.0; // maximum value of the ntp fractional part int main() { struct timeval tv; uint64_t ntp_time; uint64_t tv_ntp; double tv_usecs; gettimeofday(&tv, NULL); tv_ntp = tv.tv_sec + EPOCH; // convert tv_usec to a fraction of a second // next, we multiply this fraction times the NTP_SCALE_FRAC, which represents // the maximum value of the fraction until it rolls over to one. Thus, // .05 seconds is represented in NTP as (.05 * NTP_SCALE_FRAC) tv_usecs = (tv.tv_usec * 1e-6) * NTP_SCALE_FRAC; // next we take the tv_ntp seconds value and shift it 32 bits to the left. This puts the // seconds in the proper location for NTP time stamps. I recognize this method has an // overflow hazard if used after around the year 2106 // Next we do a bitwise AND with the tv_usecs cast as a uin32_t, dropping the fractional // part ntp_time = ((tv_ntp << 32) & (uint32_t)tv_usecs); }

• Is this good C# style?

  - by burnt1ce

  Consider the following method signature: public static bool TryGetPolls(out List<Poll> polls, out string errorMessage) This method performs the following: accesses the database to generate a list of Poll objects. returns true if it was success and errorMessage will be an empty string returns false if it was not successful and errorMessage will contain an exception message. Is this good style? Update: Lets say i do use the following method signature: public static List<Poll> GetPolls() and in that method, it doesn't catch any exceptions (so i depend the caller to catch exceptions). How do i dispose and close all the objects that is in the scope of that method? As soon as an exception is thrown, the code that closes and disposes objects in the method is no longer reachable.

• Any good card game AI strategies?

  - by Mark

  What would be strategies for writing a good computer opponent for a card game? Most card games are games of incomplete information, so simply mapping out and traversing the game tree as one could do with a board game does not seem too promising. Maybe one could track what open cards are in the game (as soon as they are revealed) and assign probabilities to certain events (e.g. opponent still has 2 cards of clubs). Does anyone have experience with this? Links and directions greatly appreciated. Thanks! -Mark

• Calculate time of method execution and send to WCF service async

  - by Tim

  I need to implement time calculation for repository methods in my asp .net mvc project classes. The problem is that i need to send time calculation data to WCF Service which is time consuming. I think about threads which can help to cal WCF service asynchronously. But I have very little experience with it. Do I need to create new thread each time or I can create a global thread, if so then how? I have something like that: StopWatch class public class StopWatch { private DateTime _startTime; private DateTime _endTime; public void Start() { _startTime = DateTime.Now; } protected void StopTimerAndWriteStatistics() { _endTime = DateTime.Now; TimeSpan timeResult = _endTime - _startTime; //WCF proxy object var reporting = AppServerUtility.GetProxy<IReporting>(); //Send data to server reporting.WriteStatistics(_startTime, _endTime, timeResult, "some information"); } public void Stop() { //Here is the thread I have question with var thread = new Thread(StopTimerAndWriteStatistics); thread.Start(); } } Using of StopWatch class in Repository public class SomeRepository { public List<ObjectInfo> List() { StopWatch sw = new StopWatch(); sw.Start(); //performing long time operation sw.Stop(); } } What am I doing wrong with threads?

• Where do I find a good explanation of Javascript-ese

  - by tzenes

  I realize that title may require explanation. The language I first learned was C, and it shows in all my programs... even those not written in C. For example, when I first learned F# I wrote my F# programs like C programs. It wasn't until someone explained the pipe operator and mapping with anonymous functions that I started to understand the F#-ese, how to write F# like a F# programmer and not a C programmer. Now I've written a little javascript, mostly basic stuff using jquery, but I was hoping there was a good resource where I could learn to write javascript programs like a javascript programmer.
