• Switching to Java from C++: What are the key points?

  - by Roddy

  I'm an experienced developer, but most of my OO programming experience has been with C++ (and a little Delphi). I'm considering doing some Android work, hence Java. Coming from the C++ background, what areas of Java are most likely to surprise/annoy/delight me? I felt sure this would already have been asked, but my searches haven't turned up a similar question. CW, of course.

• Can I make gcc tell me when a calculation results in NaN or inf at runtime?

  - by toft

  Is there a way to tell gcc to throw a SIGFPE or something similar in response to a calculation that results in NaN or (-)inf at runtime, like it would for a divide-by-zero? I've tried the -fsignaling-nans flag, which doesn't seem to help.

• What the best multi-thread application debugger for C++ apps.

  - by Coredumped

  I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

• C#: How to replace "-" with " -" only when it's not preceded by "e"?

  - by MaDDoX

  I imagine I should use Regex for that but I still scratch my head a lot about it (and the only similar question I found wasn't exactly my case) so I decided to ask for help. This is the input and expected output: Input: "c-0.68219,-0.0478 -1.01455-0.0441 0.2321e-4,0.43212" Output:"c -0.68219,-0.0478 -1.01455 -0.0441 0.2321e-4,0.43212" Basically I need either commas or spaces as value separators, but I can't break the exponential index (e-4). Maybe do two successive replacements?

• Gmail HTML5 Feature to "drop" attachments

  - by Pablo Fernandez

  I've seen this and I have to admit I'm pretty impressed: http://bit.ly/bkU9r5 I'm almost certain that this is an HTML 5 feature (it's supported on Chrome and Firefox 3.5), and was wondering if somebody knew how is the browser feature called. Bonus points for a tutorial/article on how to do something similar!

• Search tool that uses a grammar rather than regular expression?

  - by Tom Hubbard

  Are there any search tools that allow you to set up a simple token/grammar parsing system that work similar to regular expressions? What we want to do is search our ColdFusion code for queries that do not have cfqueryparams in them. A regular expression gets a bit tough in this situation because I can't keep track of the start tags while looking for something else before getting an end tag. It seems like a parsing system would work more accurately.

• Multiple repositories, single setup

  - by graham.reeds

  If I use multiple repositories, all located under a single root folder, how can I set it up so that they will use a single master svnconf/passwd file for setup but still allow me to customize each if the need arises? This is on windows but I guess the process would be similar on other systems. Update: I am using svnserve as a service.

• Indexing over the results returned by selenium

  - by Guy

  Hi I try to index over results returned by an xpath. For example: xpath = '//a[@id="someID"]' can return a few results. I want to get a list of them. I thought that doing: numOfResults = sel.get_xpath_count(xpath) l = [] for i in range(1,numOfResults+1): l.append(sel.get_text('(%s)[%d]'%(xpath, i))) would work because doing something similar with firefox's Xpath checker works: (//a[@id='someID'])[2] returns the 2nd result. Ideas why the behavior would be different and how to do such a thing with selenium Thanks

• How are the concepts of process and threads implementated in Linux kernel?

  - by Shan

  Can any one explain how are the concepts of process and threads implemented in Linux kernel ? I am looking for an intuitive explanation with some C snippets ( and important data structures) that clearly distinguishes between the two. I am just looking for the key implementation ideas I should get hold off. Essentially, I want to understand them and implement something similar in an embedded target (not supporte by any OS) in C language.

• Mercurial: include revisions in diff?

  - by David Wolever

  Is there some way to ask Mercurial to show the revisions being diffed in the output? For example: $ hg diff -r trunk:development diff -r 08d51ecf22cf:ff5673e55b9f --git a/foo.c b/foo.c ... Or something similar? I've found that there have been a few times that I've taken a diff (eg, to review), but have later been unable to recreate it because I've forgotten which revisions it was taken against.
