• Spatial Index for Rectangles With Fast Insert

  - by TheCloudlessSky

  Hello, I'm looking for a data structure that provides indexing for Rectangles. I need the insert algorithm to be as fast as possible since the rectangles will be moving around the screen (think of dragging a rectangle with your mouse to a new position). I've looked into R-Trees, R+Trees, kD-Trees, Quad-Trees and B-Trees but from my understanding insert's are usually slow. I'd prefer to have inserts at sub-linear time complexity so maybe someone can prove me wrong about either of the listed data structures. I should be able to query the data structure for what rectangles are at point(x, y) or what rectangles intersect rectangle(x, y, width, height). EDIT: The reason I want insert so fast is because if you think of a rectangle being moved around the screen, they're going to have to be removed and then re-inserted. Thanks!

• How to combine template partial specialization and template argument deduction

  - by KKKoo0

  My understanding is that template argument deduction is only for function templates, but function templates does not allow partial specialization. Is there a way to achieve both? I basically want to achieve a function-like object (can be a functor) with the signature template<class InputIterator1, class InputIterator2, class OutputIterator, int distribution> void GetQuantity(InputIterator1 frist1, InputIterator1 last1, InputIterator2 first2, OutputIterator result, double supply, double limit); Depending on the value of distribution, I want to have a couple of specializations of this template. And when I call this function,I basically do not want to specify all the type parameters, because they are many of them (and thus I need argument deduction)!

• Looking for *small*, open source, c# project with extensive Unit Testing

  - by Gern Blandston

  (I asked this question but did not receive much response. It was recommended that I ask the same question with regards to C#. ) I am a VB.NET developer with little C# experience (yes, I know I need to write more in C#), looking for small open source projects that demonstrate high unit testing coverage from which to learn. I'm looking for small projects because I don't want to have to wade through a ton of code to get a better understanding of how to apply unit testing in my own situation, in which I write mostly IT business apps used internally by my company. UPDATE: Original question that got me asking about this is here

• svn cat for git

  - by sanxiyn

  I am looking for the equivalent of svn cat in git. Yes, I am aware that the similar question was asked here. The answer is to use git show rev:path. However, svn cat can be used for the remote repository. That is, I can do svn cat url@rev and get the file from the specified revision of the remote repository, without getting the whole repository. My understanding is that git show only applies to the local repository. A workaround I found is to use gitweb interface to get the blob.

• How Can I Learn about Interfaces

  - by BDotA

  I am using C# and I know what are the interfaces and how syntatically use them,etc. but what I have not learned yet is that when I am tasked to write a project, create a component,... How should I learn better about interfaces so when I want to do something I be able to Think about using them in my design...or for example I want to learn about dependency injection or even using mocking objects for testing, these are all related to good understanding of interfaces and know when and how to use them ... Can you plase provide me some good advice, reading,... then can help me with that?

• What considerations need to be made when transitioning an application to support?

  - by Eric U.

  I will be taking on the role of support for a complex application that is transitioning from the development team. This application is a sharepoint solution that connects to several (7) web services. The development team is rolling off almost immediately and will be available only for small questions. I'm new to this role so I'm wondering what suggestions you have for me as I take on this large project. What are some considerations that should be made so that the transition to support is smooth and uninterupted? I've been reading the documentation but I can already see some gaps that need to be filled. The applicaiton is very (perhaps overly) configurable and there is lots of injected code. Stepping through the code is about the only way I can gain an understanding of what is actually happening. At this point I'm a little over whelmed and appreciate any suggestions or advice. Thanks!

• java keytool question

  - by user384706

  Hi, I created a java keystore programmatically of type jks (i.e. default type). It is initially empty so I created a DSA certificate. keytool -genkey -alias myCert -v -keystore trivial.keystore How can I see the public and private keys? I.e. is there a command that prints the private key of my certificate? I could only find keytool -certreq which in my understanding prints the certificate as a whole: -----BEGIN NEW CERTIFICATE REQUEST----- MIICaTCCAicCAQAwZTELMAkGA1UEBhMCR1IxDzANBgNVBAgTBkdyZWVjZTEPMA0GA1UEBxMGQXRo BQADLwAwLAIUQZbY/3Qq0G26fsBbWiHMbuVd3VICFE+gwtUauYiRbHh0caAtRj3qRTwl -----END NEW CERTIFICATE REQUEST----- I assume this is the whole certificate. How can I see private (or public key) via keytool? Thank you

• Curious to Know what Eclipse 'Show Heap Status' does

  - by GustlyWind

  Hi All In Eclipse (I am using 3.4 Ganymede) there is an option under Preferences>General>Show Heap Status which when checked shows near bottom of IDE like 46M of 98M and if we move the mouse over 'Recycle Bin' it says 'Run Garbage Collector'. I am curoius to know how this works.What will happen when 'Run Garbage Collector' is clicked. My enivroment set up is something like jdk6 is insatlled and IDE used for development and run in Tomcat server. So my understanding is all the objects which are run through Tomcat should be garbage collected. Is this correct. Is there a way to see what objects Eclipse identified as Garbage Cheers

• 503 (Server Unavailable) WebException when loading local XHTML file

  - by kcoppock

  Hello! So I'm currently working on an ePub reader application, and I've been reading through a bunch of regular XML files just fine with System.Xml and XmlDocument: XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(Path.Combine(Directory.GetCurrentDirectory(), "META-INF/container.xml")); XmlNodeList xnl = xmldoc.GetElementsByTagName("rootfile"); However, now I'm trying to open the XHTML files that contain the actual book text, and they're XHTML files. Now I don't really know the difference between the two, but I'm getting the following error with this code (in the same document, using the same XmlDocument and XmlNodeList variable) xmldoc.Load(Path.Combine(Directory.GetCurrentDirectory(), "OEBPS/part1.xhtml")); "WebException was unhandled: The remote server returned an error: (503) Server Unavailable" It's a local document, so I'm not understanding why it's giving this error? Any help would be greatly appreciated. :) I've got the full source code here if it helps: http://drop.io/epubtest (I know the ePubConstructor.ParseDocument() method is horribly messy, I'm just trying to get it working at the moment before I split it into classes)

• Map Custom URL protocol to HTTP (using NSURLProtocol?)

  - by Francisco Ryan Tolmasky I

  I have an application using a WebKit WebView and I'd like to map URL's that are loaded in this WebView with a custom URL protocol to a different HTTP URL. For example, say I am loading: custom://path/to/resource I would like to internally actually load: http://something-else.com/path/to/resource In other words, the custom protocol serves almost as a shorthand. I can't however use -webView:resource:willSendRequest:redirectResponse:fromDataSource:, because I want WebKit to actually believe this is the URL in question, not to simply redirect from one to the other. So far I've been attempting to use a custom NSURLProtocol subclass. However, this is proving trickier than I first thought because, at least to my understanding, I will have to do the actual loading myself in the NSURLProtocol subclass' startLoading method. I'd like a way to just hand off the work to the existing HTTP protocol loader, but I can't find an easy way to do this. Does anyone have a recommendation for this, or perhaps an alternative way to solve this issue? Thanks!

• Why & When should I use SPARSE COLUMN? (SQL SERVER 2008)

  - by priyanka.sarkar

  After going thru some tutorials on SQL SERVER 2008's new feature SPARSE COLUMN, I have found that it doesn't take any space if the column value is 0 or null but when there is a value, it takes 4 times the space a regular(non sparse) column holds. If my understanding is correct, then why I will go for that at the time of database design? And if I use that, then at what situation so I be? Also out of curiosity, how come no space get's reserve when a column is defined as sparse column(I mean to say, what is the internal implementation for that) Thanks in advance

• What is a TFS Agile Issue?

  - by Jaxidian

  With TFS2010 using the "MSF for Agile Software Development v5" process template, I'm having some difficulty in understanding exactly what an Issue is. The most specific documentation I've been able to find is this. Is an Issue a higher-level item for which we will probably generate a Bug for after some investigation in code/requirements? Or is an Issue something different than a Bug because it has not actually a mistake in code but is more of a critical oversight in design (for example, there was never an attempt to create a datepicker for all date fields and this is a UX issue but not really a bug) and therefore a change request of sorts? Or is it something different?

• Git pack file entry format

  - by Ben Collins

  My understanding of the Git pack file format is something like: Where the table is 32-bits wide, and the first three 32-bit words are the pack file header. The last row of 32 bits are the first 4 bytes of an entry. As I understand it, the size of the entry is specified by consecutive bytes with the MSB set, followed by compressed data. In the first byte whose MSB is not set, is the MSB part of the compressed data, or is it a gap? If it's part of the compressed data, how can you guarantee that when the data is compressed that bit won't be set?

• Confused about using SpringMVC Vs JEE project in Netbeans

  - by Sanju

  Hi all, I want to start a my first JEE project. I have read a lot that springMVC framework is a good choice (never used though) My earlier experience with java is not much. only some small app development using Netbeans. so I have some experience using Netbeans. but I see that I can start a JEE project in Netbeans. so what kind of framework netbeans is using underneath. PS: My understanding of framework (e.g. SpringMVC) is that you follow rule of framework to configure your app. and then framework take care or linking your View, controller and model. so if i am using netbeans, do i need to take care of linking of my MVC by myself?

• WHERE clause confusion with PDO

  - by Greg

  I'm having some trouble understanding how to use prepared statements, when you need to match one value against several columns at once. In other words what instead of doing this: $stmt = $dbh-prepare("SELECT * FROM REGISTRY where name = ?"); $stmt-bindParam(':name', $name); I wanted to do this: $stmt = $dbh-prepare("SELECT * FROM REGISTRY where firstname = ? or lastname = ?"); with both '?' representing the same string.

• CSS class equivalent for LaTeX

  - by Ryan Scott Bardsley

  I am trying to figure out if there is a way to apply the CSS methodology to the LaTeX template I am building. What I would like to do is to have a set of classes that apply a specific style treatment to the bracketed words. For example: If I have three paragraphs of text, I want to have all of the paragraphs have [0.5cm] of spacing after the last line without having to add \\[0.5cm] after each paragraph. Is there a LaTeX equivalent of defining the treatment for all paragraphs in the preamble so that it cascades throughout my document? The equivalent of: <style> p {padding-bottom:0.5cm} </style> I want to be able to specify multiple version of these CSS-like LaTeX classes throughout my document, so I don't need a specific solution. I need help understanding how to add custom labels/names/classes to the preamble and an example of how to use them in the document itself. Thanks! Ryan

• Question about "Link Map" output and "Assume" directive of MASM assembler.

  - by smwikipedia

  I am new to MASM. So the questions may be quite basic. When I am using the MASM assembler, there's an output file called "Link Map". Its content is composed of the starting offset and length of various segments, such as Data segment, Code segment and Stack segment. I am wondering that, where are these information describing? Are they talking about how various segments are located within an EXE file or, how segments are located within memory after the EXE file being loaded into memory by a program loader? BTW: What does the "Assume" directive do? My understanding is that it tell the assembler to emit some information into the exe file header so the program loader could use it to set DS, CS, SS, ES register accordingly. Am I right on this? Thanks in advance.

• Theory of computation - Using the pumping lemma for context free languages

  - by Tony

  I'm reviewing my notes for my course on theory of computation and I'm having trouble understanding how to complete a certain proof. Here is the question: A = {0^n 1^m 0^n | n>=1, m>=1} Prove that A is not regular. It's pretty obvious that the pumping lemma has to be used for this. So, we have |vy| = 1 |vxy| <= p (p being the pumping length, = 1) uv^ixy^iz exists in A for all i = 0 Trying to think of the correct string to choose seems a bit iffy for this. I was thinking 0^p 1^q 0^p, but I don't know if I can obscurely make a q, and since there is no bound on u, this could make things unruly.. So, how would one go about this?

• Hibernate and stored procedures

  - by cc96ai

  As my understanding on setting hibernate, I need to create table meta data file (person.hbm.xml), include all the fields mapping java object (person.java) If we use stored procedures for all transaction, do we still need the above configuration? It seems hibernate and stored procedures will overlap, We set up the stored procedure because we don't want the to developer know all the field in db. If tables change, then we need update above files. Does it mean if we purely use stored procedure, we should just go for JDBC? If hibernate, we should stay in HQL?

• Need post-it notes that don't fall off the whiteboard after a week.

  - by jdv

  In my company, we plan our develpment work with scrum. We track progress using post-it stickies on a big whiteboard, and it works great. It is my understanding that's kind of standard. We are just one location, so we don't need or want to do this electronically. But to our (and the Q/A rep's) annoyance, the sticky notes begin to fall off the whiteboard after a week or two, or even sooner if you stick them on top of each other. I've experimented with extra tape on the stickies. That helped, but it also ruins the whiteboard. So I am looking for a pragmatic and preferably low-cost alternative. Are some post-it brands better than others? Or do you have another solution for a scrum board does not suffer from this?

• Can someone explain me implicit conversions in Scala?

  - by Oscar Reyes

  And more specifically how does the BigInt works for convert int to BigInt? In the source code it reads: ... implicit def int2bigInt(i: Int): BigInt = apply(i) ... How is this code invoked? I can understand how this other sample: "Date literals" works. In. val christmas = 24 Dec 2010 Defined by: implicit def dateLiterals(date: Int) = new { import java.util.Date def Dec(year: Int) = new Date(year, 11, date) } When int get's passed the message Dec with an int as parameter, the system looks for another method that can handle the request, in this case Dec(year:Int) Q1. Am I right in my understanding of Date literals? Q2. How does it apply to BigInt? Thanks

• Twitter - Get users live tweets on my website instantly

  - by Gublooo

  Hello guys, I was checking out the stocktwits.com website. While signing up I provided them with my twitter username. Now whenever I tweet and if my tweet contains $ and a stock ticker symbol - it instantly appears on Stocktwits.com I am interested in implementing something similar in my website. Just wanted an understanding of how this would work. This is how I'm assuming it would work at a high level: 1) On my website - require users to provide their twitter usernames 2) Run a cron job every few minutes to pull the latest tweets for each of the usernames provided using something like http://twitter.com/statuses/user_timeline/username.xml I've tried Stocktwits and they updates are almost instantaneous - so it does not appear like they are checking for updates every few minutes. What are the best ways to implement this solution Thanks

• DWR and Jquery into spring MVC 2.5

  - by Mark Estrada

  Hi, From my shallow reading, Spring MVC does not support jquery directly. It does enable integration with DWR framework. From my understanding of DWR, it is an ajax framework that allows you to call javas methods from javascript. Can I use both in my application? With Jquery handling most of the javascript code and client side interaction and DWR making the ajax calls? I am leaning towards learning jquery but there is no out of the box support for it in spring 2.5.

• How to learn flex?

  - by Zenzen

  So I'm starting an internship as a Flex developer in ~2weeks thanks to a friend of mine. The thing is I know squat about Flex - it is an internship after all so I'm supposed to learn there, but nonetheless I want to have some basic understanding of Flex before I start (eventually I want to become a JEE/Flex dev). So my question is simple, which book(s) would you recommend me to start with? Are there any "must have" books, like let's say "Thinking in C++" for C++ etc.? I already heard about a few video tutorials and I will surely check them out but I'd also want to get some decent books.
