  • maven-jar-plugin includes vs excludes

    - by Chris Williams
    I've got an existing pom file that includes a maven-jar-plugin section. It runs for the test-jar goal and is currently excluding a few directories: <excludes> <exclude>...</exclude> <exclude>...</exclude> <exclude>somedir/**</exclude> </excludes> I need to include a file in the somedir directory but leave out the rest of the files in the somedir directory. I've read that includes have precedence over excludes so I added something like the following (there was no includes section before): <includes> <include>somedir/somefile.xml</include> </includes> This ends up creating a jar file for test with only a few files in it (just the stuff in META-INF). The file that I included is not in the jar either. What I'd expect is a jar that is identical to the jar that was created before my includes change with the one additional file. What am I missing here?

  • Implementing Security on custom BCS/.net class?

    - by Michael Stum
    I'm implementing a custom BCS Model to get data from a backend system. As the backend uses it's own user management, I'm accessing it through a service account. All of this works well and allows me to pull data into SharePoint. However because it's channeled through the service account, everyone can access it, which is bad. Can anyone give me some tips which method to implement? The backend does not give me NT ACLs, but I wonder if I could just "fake" them somehow? (Essentially saying "This NT Group has Read Access" is good enough). I am aware of ISecurityTrimmer2 for Search Results, but ideally I want to cover security inside the BCS Model so that it applies to external lists as well. I want to avoid using Secure storage and mapping each individual user to the backend.

  • Event Capturing vs Event Bubbling

    - by Rajat
    I just wanted to get the general consensus on which is a better mode of event delegation in JS between bubbling and capturing. Now I understand that depending on a particular use-case, one might want to use capturing phase over bubbling or vice versa but I want to understand what delegation mode is preferred for most general cases and why (to me it seems bubbling mode). Or to put it in other words, is there a reason behind W3C addEventListener implementation to favor the bubbling mode. [capturing is initiated only when you specify the 3rd parameter and its true. However, you can forget that 3rd param and bubbling mode is kicked in] I looked up the JQuery's bind function to get an answer to my question and it seems it doesn't even support events in capture phase (it seems to me because of IE not support capturing mode). So looks like bubbling mode is the default choice but why?

  • Turing Model Vs Von Neuman model

    - by Santhosh
    First some background (based on my understanding).. The Von-Neumann architecture describes the stored-program computer where instructions and data are stored in memory and the machine works by changing it's internal state, i.e an instruction operated on some data and modifies the data. So inherently, there is state msintained in the system. The Turing machine architecture works by manipulating symbols on a tape. i.e A tape with infinite number of slots exists, and at any one point in time, the Turing machine is in a particular slot. Based on the symbol read at that slot, the machine change the symbol and move to a different slot. All of this is deterministic. My questions are Is there any relation between these two models (Was the Von Neuman model based on or inspired by the Turing model)? Can we say that Turing model is a superset of Von Newman model? Does functional Programming fit into Turing model. If so how? (I assume FP does not lend itself nicely to the Von Neuman model)

  • XML flat file vs. relational database backend

    - by donpal
    Most projects now need some form of a database. When someone says database, I usually think relational databases, but I still hear about flat file XML databases. What parameters do you take into consideration when deciding between a "real" database and a flat-file XML database. When should one be used over the other, and under what circumstances should I never consider using a flat file (or vice versa a relational) database?

  • "Push" linq vs reactive framework

    - by Benjol
    (Once again exposing the depths of my ignorance here by combining two concepts which I haven't grokked) I read here about the Reactive framework being a 'Push' model compared to Linq's 'Pull' model. This reminded me of reading an article about 'Push' Linq. Is there really any similarity between these two 'frameworks'? UPDATE Since I asked this question, Jon Skeet has asked it too, here are his first and second impressions.

  • Method signature Vs function prototype

    - by Maroloccio
    A formal definition of the two? Current Wiki articles denote their different contexts and applications, such as internal type signature "strings" in Java VMs (1) and C/C++ function prototypes informing compilers of upcoming method definitions (2) but... 1) http://en.wikipedia.org/wiki/Type_signature 2) http://en.wikipedia.org/wiki/Function_prototype ... where to look for a definition which clearly and formally distinguished one from the other? There is literature using the words prototype and signature almost interchangeably yet other uses appear strict and consistent, if language-specific. Background: I am writing documentation for a sample compiler written for a University project.

  • rails + compass: advantages vs using haml + blueprint directly

    - by egarcia
    I've got some experience using haml (+sass) on rails projects. I recently started using them with blueprintcss - the only thing I did was transform blueprint.css into a sass file, and started coding from there. I even have a rails generator that includes all this by default. It seems that Compass does what I do, and other things. I'm trying to understand what those other things are - but the documentation/tutorials weren't very clear. These are my conclusions: Compass comes with built-in sass mixins that implement common CSS idioms, such as links with icons or horizontal lists. My solution doesn't provide anything like that. (1 point for Compass). Compass has several command-line options: you can create a rails project, but you can also "install" it on an existing rails project. A rails generator could be personalized to do the same thing, I guess. (Tie). Compass has two modes of working with blueprint: "basic" and "semantic" usage. I'm not clear about the differences between those. With my rails generator I only have one mode, but it seems enough. (Tie) Apparently, Compass is prepared to use other frameworks, besides blueprint (e.g. YUI). I could not find much documentation about this, and I'm not interested on it anyway - blueprint is ok for me (Tie). Compass' learning curve seems a bit stiff and the documentation seems sparse. Learning could be a bit difficult. On the other hand, I know the ins and outs of my own system and can use it right away. (1 point for my system). With this analysis, I'm hesitant to give Compass a try. Is my analysis correct? Are Am I missing any key points, or have I evaluated any of these points wrongly?

  • c# WebRequest class and headers

    - by Sir Psycho
    Hi, When I try to set the header properties on a WebRequest object, I get the following exception This header must be modified using the appropriate property I've tried modifying the .Headers propery and adding them that way like so webRequest.Headers.Add(HttpRequestHeader.Referer, "http://stackoverflow.com"); But still getting exceptions. I can get around this by casting the WebRequest object to a HttpWebRequest and setting the properties such as httpWebReq.Referer ="http://stackoverflow.com" But I'd like to know if there's a way to get a finer grained control over modifying headers with a request for a remote resource. Thanks

  • text indexes vs integer indexes in mysql

    - by imanc
    Hey, I have always tried to have an integer primary key on a table no matter what. But now I am questioning if this is always necessary. Let's say I have a product table and each product has a globally unique SKU number - that would be a string of say 8-16 characters. Why not make this the PK? Typically I would make this field a unique index but then have an auto incrementing int field as the PK, as I assumed it would be faster, easier to maintain, and would allow me to do things like get the last 5 records added with ease. But in terms of optimisation, assuming I'd only ever be matching the full text field and next doing text matching queries (e.g. like %%) can you guys think of any reasons not to use a text based primary key, most likely of type varchar()? Cheers, imanc

  • IBM WebSphere vs Oracle Fusion

    - by Hal
    I have been asked to research the advantages/disadvantages the two application servers, but am new to the space and am having a terrible time finding an unbiased comparison of the two platforms. I understand that this is a broad question and I hate that I can't give a very specific use case (other than it will be an implementation in an organization with out a full time admin dedicated to management and it will be running in a mixed environment against JD Edwards/Oracle and SQLServer). Does anyone know of any (recently published) content that does a reasonable comparison or can any offer any insight into which might be the better choice and why. Any help would be greatly appreciated. Best regards, Hal

  • Python 2 vs Python 3 and Tutorial

    - by MR-J
    Hey guys. I am 12 years old and I have had a small amount of experience with BASIC. I am thinking about learning Python, but I’m not sure if I should learn the 2.6 version or the 3.0 version. I don’t really care about the support for libraries or anything along those lines quite yet. I was wondering if it is easier to code in 3.0 than 2.6. And is it more fun and productive? I would also appreciate it if you could point me in the right direction for a simple yet complete tutorial that is easy to understand and possible teaches Object Oriented Programing. I don’t really care if it teaches OOP or not. One more thing; if I do learn python, is it possible to easily compile a python source code file into a 'stand-alone' .exe file for Windows? I really liked that functionality in BASIC. Thanks!!!!

  • Python twisted Reactor class

    - by anijhaw
    What is the significance of the decorators @reactor.callWhenRunning, @results_deferred.addCallback @results_deferred.addErrback. Also what are deferred strings, for example in the twisted.internet.utils.getProcessOutput() returns a deferred string what exactly is happening here? I am new to twisted hence this might be a very simple question but reading twisted documentation did not help me much

  • Flash vs. Ajax Abilities

    - by Alex
    Hey everyone. I want to develop an application that does a bunch of cool stuff. The first thing that I need in it is to get information about the page a person is browsing. With that said, I need for example to know how long a user stayed in a page and where was the scrollbar. While getting that data, It's all saved to a database. The thing is, I prefer doing that in Flash [although I have no experience in it] over Ajax since I want to hide the code - which as far as I know not possible in Javascript/Ajax. So, can I do all that in Flash? - Read the content of the page, get the status of the scroll bar.. Plus, I then need to go threw the gathered information that is saved in the database. Since there could be many calculations i thought C++ .Net is better than PHP [which I know better]. Is that all possible or am I just crazy? :) Thanks ahead.

  • asp.net controls vs html element security?

    - by Eyla
    In general, If I have a choice when developing a web site to use html elements or asp.net controls which one is better to use if my website is interactive with server side operations such as accessing database. Is it more secure to use asp.net controls or does not matter. On other words, is it more secure to use asp.net controls instead of html element to deliver data or receive data from/to server side or no differences?

  • "Android 2.x" vs "Google APIs" for Android AVD Setup

    - by Adam Haile
    In the Android AVD manager (or a new project for that matter), it will give two options for the same API level. For example, for Level 7 (2.1) it will show "Google APIs - Level 7" and "Android 2.1 - Level 7" in the selection drop down. What, if any, is the actual difference between these two and why would I want one over the other?

P.S. ???? ?? ??????, ?????? ???????? ?? ?????: [email protected] Google translation (I cleaned this up a but, don't don't speak russian, someone else please improve if it's wrong) Hello, ANRY! Most recently, during the passage of the practice of the university, faced with NHibernate. I read your article "Hello NHibernate!". Took to implement something like a store: that is, a product, the customer order. Accordingly created 4 tables in MSSQL 2010: Goods (id_tovara, name, price) Client (id_klienta, name, surname) Order (id_zakaza, id_klienta, cost) Order Line (id_stroki order id_zakaza, id_tovara, quantity) Accordingly, created 4 classes: Product, Customer, Order, Order Line. my question is this: whether you want to create 4 mapping-file, or you can make only one? And when there is a Debug gives the following error: "Could not compile the mapping document: Sklad.products.hbm.xml. And "Build" is normal, no errors. In what may be the problem and how it can solve? Regards, Andrew. PS if not difficult, you can reply to e-mail: [email protected]

  • Core Data vs. SQLitePersistentObjects

    - by Macatomy
    I'm creating an iPhone app and I'm trying to choose between 2 solutions for a persistent store. Core Data, or SQLitePersistentObjects. Basically, all my app needs is a way to store an array of model objects and then load them again to display in a UITableView. Its nothing too complicated. Core Data seems to have a much higher learning curve than the simple to use SQLitePersistentObjects. Are there any obvious benefits of using Core Data over SQLitePersistentObjects in my case?
