  • Recommended reading for bioinformatics

    - by Matt
    I'm keen on learning about bioinformatics. I am ideally looking for a short course introduction, with some practical tasks I can get my teeth into immediately to see if there is any interest in it for me. I already have a good understanding of molecular biology, so I should be able to skip most of the foundational work. Any suggestions?

  • What is the best way to handle my softwares licenses?

    - by Sergio Tapia
    By best I mean more time tested, easier to implement and easier for the users to work with. I do not want my licensing crap to interfere with their work. I was thinking of launching a WCF service that check with my license DB if it's a valid license and if it is, send a True. If the returned response is False, then shut down the program after telling them to fix their license. Do you think this is a good way to handle it?

  • Best practices regarding equals: to overload or not to overload?

    - by polygenelubricants
    Consider the following snippet: import java.util.*; public class EqualsOverload { public static void main(String[] args) { class Thing { final int x; Thing(int x) { this.x = x; } public int hashCode() { return x; } public boolean equals(Thing other) { return this.x == other.x; } } List<Thing> myThings = Arrays.asList(new Thing(42)); System.out.println(myThings.contains(new Thing(42))); // prints "false" } } Note that contains returns false!!! We seems to have lost our things!! The bug, of course, is the fact that we've accidentally overloaded, instead of overridden, Object.equals(Object). If we had written class Thing as follows instead, then contains returns true as expected. class Thing { final int x; Thing(int x) { this.x = x; } public int hashCode() { return x; } @Override public boolean equals(Object o) { return (o instanceof Thing) && (this.x == ((Thing) o).x); } } Effective Java 2nd Edition, Item 36: Consistently use the Override annotation, uses essentially the same argument to recommend that @Override should be used consistently. This advice is good, of course, for if we had tried to declare @Override equals(Thing other) in the first snippet, our friendly little compiler would immediately point out our silly little mistake, since it's an overload, not an override. What the book doesn't specifically cover, however, is whether overloading equals is a good idea to begin with. Essentially, there are 3 situations: Overload only, no override -- ALMOST CERTAINLY WRONG! This is essentially the first snippet above Override only (no overload) -- one way to fix This is essentially the second snippet above Overload and override combo -- another way to fix The 3rd situation is illustrated by the following snippet: class Thing { final int x; Thing(int x) { this.x = x; } public int hashCode() { return x; } public boolean equals(Thing other) { return this.x == other.x; } @Override public boolean equals(Object o) { return (o instanceof Thing) && (this.equals((Thing) o)); } } Here, even though we now have 2 equals method, there is still one equality logic, and it's located in the overload. The @Override simply delegates to the overload. So the questions are: What are the pros and cons of "override only" vs "overload & override combo"? Is there a justification for overloading equals, or is this almost certainly a bad practice?

  • How can I pre-compress files with mod_deflate in Apache 2.x?

    - by Otto
    I am serving all content through apache with Content-Encoding: zip but that compresses on the fly. A good amount of my content is static files on the disk. I want to gzip the files beforehand rather than compressing them every time they are requested. This is something that, I believe, mod_gzip did in Apache 1.x automatically, but just having the file with .gz next to it. That's no longer the case with mod_deflate.

  • Basic xhtml/css models ?

    - by Skeptic
    Hi, I need to produce a very simple website (no dynamic-content, 2-columns, header&footer) and I have a basic knowledge of xhtml/css. So I could probably come with something from scratch, but it would probably won't work in "all" browsers. I've done some googling, but it's difficult for me to evaluate the quality of the "free templates" advertized all over the place. So is there any web developer here that has good references or even such models/templates ?

  • c++ dynamic_cast error handling

    - by Nazgob
    Is there any good practice related to dynamic_cast error handling (except not using it when you don't have to)? I'm wondering how should I go about NULL and bad_cast it can throw. Should I check for both? And if I catch bad_cast or detect NULL I probably can't recover anyway... For now, I'm using assert to check if dynamic_cast returned not NULL value. Would you accept this solution on a code review?

  • Have you read any ASP.NET MVC 2.0 book?

    - 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 2.0 book? If so, how was it?

  • cpp/Qt : per class debugging

    - by dzen
    I'm developing a Qt application. For each class, I'm trying to mimic the framework, such as error() and errorString() method, use of Private implementation. But I would like to add a per class debugging: Set a macro to the desired level of debug, have a macro or a function that knows the level of debug, and use qDebug() or qWarning() which is class independant, and will know the current class's name (for some pretty prints) Anyone have a good idea to implement this ?

  • What are my best ASP.Net GridView replacement options?

    - by Homer
    We currently use a GridView to display 1000+ rows of data. Minimum requirement for replacement is a fixed header row, fixed footer and columns would be a plus. This would have to work across IE 6 and greater. I've heard good things about Infragistics, but the demo on their page is slow. So what are my best options? jQuery? YUI? other 3rd party?

  • Static DataService class vs. IRepository<T> ?

    - by msfanboy
    Hello, I am just studying the code of Sacha Barbers MVVM framework Chinch and I saw this in the xxxViewModel.cs file: DataService.FetchAllOrders(CurrentCustomer.CustomerId.DataValue); DataService is a Static class. Being a junior dev I am only used to Interfaces with Data services. Why is that class static? Or do you think he made it just for the example? So is that a good approach?
