    A little question about the listing in iphone os and some other applications, and possibly in android market.

But the main question is: Is that possible to make for firefox users with javascript, ajax or possibly any other language? out

  • Downsides to using FakeWeb compared to writing mocks for testing

    - by ajmurmann
    I never liked writing mocks and a while ago someone here recommended to use FakeWeb. I immediately fell completely in love with FakeWeb. However, I have to wonder if there is a downside to using FakeWeb. It seems like mocks are still much more common, so I wonder what I am missing that's wrong with using FakeWeb instead. Is there a certain kind of error you can't cover with Fakeweb or is it something about the TDD or BDD process?

  • Kernel config file generator

    - by lisak
    Hey guys, could please anybody recommend some kind of kconfig generator that would trim modules and built-in stuff that is not needed according to current hardware ? The best I have found is this : http://lkml.org/lkml/2008/9/16/290 I don't care about compilation time and the amount of modules that are not built-in. I'm concerned about performance. I don't know how much memory and runtime is wasted on huge kernels with almost everything possible. I'm a java developer and I don't know what most of the modules and drivers are for. So there is not much I can disable and be sure that I don't screw it up. Thanks in advance

  • How to copy subversion repository as a new directory to existing repository?

    - by Juha Syrjälä
    I have two existing subversion repositories on different hosts (host-a and host-b) and I'd like to copy one directory from repo A to repo B. Basically https://host-a/repo/some/path/moduleA should be copied to https://host-b/repo/some/other/path/moduleA. All the history should be preserved and existing data in host-b should be preserved. The two repositories do not have any conflicting directory hierarchies. The repositories do not share common ancestry.

  • Using Castle DynamicProxy is it possible to change the invocation target on class proxy?

    - by Gareth D
    Hi Using Castle DynamicProxy v2, I'd like to change the target of an invocation for a class proxy. The new target is simply a different instance of the same type as the original target. The target types do not implement a common interface so I cannot use the IProxyTargetAccessor as detailed in Krzysztof's post on the subject - I cannot cast from a class proxy invocator to a IProxyTargetAccessor. Is there a way to do this?

  • Useful Java Annotations

    - by Jon
    I'm interested in finding out exactly which Java annotations people think are most useful during development. This doesn't necessarily have to limited to the core Java API, you may include annotations you found in third party libraries or annotations you've developed yourself (make sure you include a link to the source). I'm really interested in common development tasks rather than knowing why the @ManyToOne(optional=false) in JPA is awesome... Include the annotation and a description of why it's useful for general development.

  • How does MySQL's ORDER BY RAND() work?

    - by Eugene
    Hi, I've been doing some research and testing on how to do fast random selection in MySQL. In the process I've faced some unexpected results and now I am not fully sure I know how ORDER BY RAND() really works. I always thought that when you do ORDER BY RAND() on the table, MySQL adds a new column to the table which is filled with random values, then it sorts data by that column and then e.g. you take the above value which got there randomly. I've done lots of googling and testing and finally found that the query Jay offers in his blog is indeed the fastest solution: SELECT * FROM Table T JOIN (SELECT CEIL(MAX(ID)*RAND()) AS ID FROM Table) AS x ON T.ID >= x.ID LIMIT 1; While common ORDER BY RAND() takes 30-40 seconds on my test table, his query does the work in 0.1 seconds. He explains how this functions in the blog so I'll just skip this and finally move to the odd thing. My table is a common table with a PRIMARY KEY id and other non-indexed stuff like username, age, etc. Here's the thing I am struggling to explain SELECT * FROM table ORDER BY RAND() LIMIT 1; /*30-40 seconds*/ SELECT id FROM table ORDER BY RAND() LIMIT 1; /*0.25 seconds*/ SELECT id, username FROM table ORDER BY RAND() LIMIT 1; /*90 seconds*/ I was sort of expecting to see approximately the same time for all three queries since I am always sorting on a single column. But for some reason this didn't happen. Please let me know if you any ideas about this. I have a project where I need to do fast ORDER BY RAND() and personally I would prefer to use SELECT id FROM table ORDER BY RAND() LIMIT 1; SELECT * FROM table WHERE id=ID_FROM_PREVIOUS_QUERY LIMIT 1; which, yes, is slower than Jay's method, however it is smaller and easier to understand. My queries are rather big ones with several JOINs and with WHERE clause and while Jay's method still works, the query grows really big and complex because I need to use all the JOINs and WHERE in the JOINed (called x in his query) sub request. Thanks for your time!

  • Regex: How do I match some regex logic 1 or more times?

    - by tom
    I already have some regex logic which says to look for a div tag with class=something. However, this might occur more than once (one after another). You can't simply add square brackets around that complex regex logic already (e.g. [:some complicated regex logic already existing:]* -- so how do you do it in regex? I want to avoid having to use the programming language logic to append that regex logic after itself if I can... Thanks

  • Is Programming Right for me?

    - by L1th1um
    I'm interested in programming, but it seems to me that I can't get into it. Every time I've tried to learn a language and stuff by looking through tutorials or books I'd never get past the part where I use the syntax to make something. And by interest, I mean that I read stack overflow a lot, coding horror, and stuff but the actual coding part is hard for me to get into. Did anybody start this way? How did you get past this block?

    - by user171523
    I am in the process of building a system where i need to notify a Window Service a .net based application in case of any change in the DB table (Insert , Update , Delete). I know this can be done with the ADO.NET Events in SQL. Is there any common solution for Oracle and SQL which can provide this kind of notifications. This needs to happen as and when the update happens on real time basis.
