  • Java - Collections.sort() performance

    - by msr
    Hello, Im using Collections.sort() to sort a LinkedList whose elements implements Comparable interface, so they are sorted in a natural order. In the javadoc documentation its said this method uses mergesort algorithm wich has n*log(n) performance. My question is if there is a more efficient algorithm to sort my LinkedList? The size of that list could be very high and sort will be also very frequent. Thanks!

  • Insight into how things get printed onto the screen (cout,printf) and origin of really complex stuff

    - by sil3nt
    I've always wondered this, and still haven't found the answer. Whenever we use "cout" or "printf" how exactly is that printed on the screen?. How does the text come out as it does...(probably quite a vague question here, ill work with whatever you give me.). So basically how are those functions made?..is it assembly?, if so where does that begin?. This brings on more questions like how on earth have they made openGl/directx functions.. break it down people break it down.:)

  • When are child views added to Layout/ViewGroup from XML

    - by JohnTube
    My question is : I want to know when does a xLayout (or ViewGroup in general) add a child view from XML ? And by "when" I mean at what point of code, in what "pass" of the "traversal" of the UI toolkit ? Which method of xLayout or ViewGroup should I override ? I have done my homework : I have watched the "Writing Custom Views For Android" presented (by Adam Powell and Romain Guy) in the last Google I/O and I have read Adam Powell comments on this Google+ post.

  • What is the best way to read and write cXML documents in C# ?

    - by tetranz
    I know this is a vague open ended question. I'm hoping to get some general direction. I need to add cXML punchout to an ASP.NET C# site / application. This is replacing something that I wrote years ago in ColdFusion. I'm a reasonably experienced C# developer but I haven't done much with XML. There seems to be lots of different options for processing XML in .NET. Here's the open ended question: Assuming that I have an XML document in some form, eg a file or a string, what is the best way to read it into my code? I want to get the data and then query databases etc. The cXML document size and our traffic volumes are easily small enough so that loading the a cXML document into memory is not a problem. Should I: 1) Manually build classes based on the dtd and use the XML Serializer? 2) Use a tool to generate classes. There are sample cXML files downloadable from Ariba.com. I tried xsd.exe to generate an xsd and then xsd.exe /c to generate classes. When I try to deserialize I get errors because there seems to be "confusion" around whether some elements should be single values or arrays. I tried the CodeXS online tool but that gives errors in it's log and errors if I try to deserialize a sample document. 2) Create a dataset and ReadXml()? 3) Create a typed dataset and ReadXml()? 4) Use Linq to XML. I often use Linq to Objects so I'm familiar with Linq in general but I'm struggling to see what it gives me in this situation. 5) Some other means. I guess I need to improve my understanding of XML in general but even so ... am I missing some obvious way of doing this? In the old ColdFusion site I found a free component ("tag") which basically ignored any schema and read the XML into a "structure" which is essentially a series of nested hash tables which was then easy to read in code. That was probably quite sloppy but it worked. I also need to generate XML files from my C# objects. Maybe Linq to XML will be good for that. I could start with a default "template" document and manipulate it before saving. Thanks for any pointers ...

  • What are some fun project ideas for a new Python developer?

    - by Sergio Tapia
    I'm new to Python 3 and so far it seems like a decent language. I really like the string manipulation methods you can use and they are pretty radical. :) I'm stuck however in thinking of a project to do with Python. Is there a site similar to Coding4Fun but for Python? Community Wiki because I think this question is really interesting. :D

  • What is the best Django syncdb crash debugging technique ?

    - by user367752
    What is the best Django syncdb crash debugging technique ? I've previously asked a question about a problem with manage.py syncdb returning an exception and the answer was that the app has a wrong import. http://stackoverflow.com/questions/2734721/django-manage-py-syncdb-not-working I'd like to know the technique used to find the place where there is a wrong import. I tried ./manage.py syncdb --verbosity=2 but I didn't get any more information that way.

  • HTML Types - Learning Order?

    - by Gabe
    I've decided that today - as soon as this question is answered, in fact - I'm going to dive into learning HTML. But, looking online, I've noticed there are many types: HTML, XHTML, HTML5, and so on. So, which should I start with? In what order should I learn them? And, for that first language, where should I learn at?

  • How do you use technology to memorize set of terms?

    - by user49767
    Always there are few set of items needs to be memorized in short span of time. Here are my following cases. 1) My Job requires some set of items needs to be memorized. 2) I am a developer who has to learn 150+ tags within next 3 days. 3) Fix developer/support has to remember minimum of 125+ tags (set of possible values). 4) It is better if team's SQL developer knows all the table and columns in my database. 5) When guys join new department or job. Memorizing few related items will definitely gives some benefit. Most of the cases, I suggest people to understand the domain better and nothing wrong in using google (but remember correct search-word). But recently I came across a junior developer who took lot of effort in memorizing set of things (150+ table structures, fix protocol tags, almost 300+ configuration items from property file) and was very very successful in his job and was swift in responding for support queries. Needless to say he is smart worker too (not a dumb guy). When I try to recollect some of the successful employees I met, they were so good in remembering entire schema and they did in short span of time. But I don't argue that memorizing alone gives success, but it greatly helps when situation demands. Here my question is, I am not good at remembering things, but it shouldn't be lame excuse. Hence I am evaluating using technolgies better to memorize set of items. Not very much interested in memory techniques (mnemoninc, photography memory, etc..). Even I have recorded 100+ items and listen to that whenever I found free time, defintely there were some fruitful result. Now I need your suggestion about what are all the ways to exploit technology to memorize. There could be so many reason why guys remember a subject (passionate, essential, author, creator, responsbile). Not interested in dissecting why guys remeber. Rather much interested in using ways, and techniques (cheat sheet...) to remember a set of itmes. Note : I appreciate, encourage people who could rephrase my question better. Note : I have kept couple of cheat-sheet close to my monitor, honestly it did not help me :).

  • Cross-Browser CSS3 Rule

    - by Alexander Corotchi
    I have a stupid question, If I want to add round corner for an element in browsers which support some stuff of CSS3, I have to repeat style several time for each browser, because it is different ? For ex : -moz-border-radius: 12px; /* FF1+ */ -webkit-border-radius: 12px; /* Saf3+, Chrome */ border-radius: 12px; /* Opera 10.5, IE 9 */ It means, that I have to add 3 styles for this radius border, doesn't it ?

  • Calculate broadcast address given IP address and subnet in PowerShell

    - by halr9000
    My goal is to calculate the broadcast address when given the IP and subnet mask of a host node. I know, sounds like homework. Once I reasoned through my task and boiled it down to this, I was amused with myself. Anyway, the solution will look something like the one in this question I suppose, but I'm not a math major and my C sucks. I could do with a PowerShell (preferred) or C# example to get me going. thanks!

  • Stopping infinite loops of alerts in Mozilla

    - by Christy John
    This may be dumb question. But somehow this engaged me for sometime and after some basic research I couldn't find an answer. I was learning JavaScript and a code I wrote had an error and has been outputting infinite loops of alerts. I tried the normal shortcuts like Ctrl + C and Ctrl + Z but they didn't work. So I was thinking if there is any solution to this other than ending the browser process (like by doing a Ctrl + Alt + Del).
