  • Should I use a unit testing framework to validate XML documents?

    - by christofr
    From http://www.w3.org/XML/Schema: [XML Schemas] provide a means for defining the structure, content and semantics of XML documents. I'm using an XML Schema (XSD) to validate several large XML documents. While I'm finding plenty of support within XSD for checking the structure of my documents, there are no procedural if/else features that allow me to say, for instance, If Country is USA, then Zipcode cannot be empty. I'm comfortable using unit testing frameworks, and could quite happily use a framework to test content integrity. Am I asking for trouble doing it this way, rather than an alternative approach? Has anybody tried this with good / bad results? -- Edit: I didn't include this information to keep it technology agnostic, but I would be using C# / Linq / xUnit for deserialization / testing.

  • Frustrated by the VS2012 'Light' and 'Dark' themes?

    - by ihaynes
    Like me you may be have been frustrated by the lack of colour in VS2012. The flat look, reminicent of the early 'Gem' OS is bad enough, but when the only choices are a washed out white look or the deadly all-black look, it's not an easy product to work with.Fortunately MS themselves seem to have quietly taken notice of this, or at least one of their developers has, and a 'Color Theme Editor' extension has been released. This comes with some much better colour schemes (I'm using the blue one, which is fairly close to VS2010) and also allows you to create and edit themes youself.This extension doesn't come up when you search 'Extensions and Updates' but can be found at http://tinyurl.com/6rhkdejWith this, using VS2012 finally becomes a pleasurable experience.

  • Do I lose/gain performance for discarding pixels even if I don't use depth testing?

    - by Gajoo
    When I first searched for discard instruction, I've found experts saying using discard will result in performance drain. They said discarding pixels will break GPU's ability to use zBuffer properly because GPU have to first run Fragment shader for both objects to check if the one nearer to camera is discarded or not. For a 2D game I'm currently working on, I've disabled both depth-test and depth-write. I'm drawing all objects sorted by their depth and that's all, no need for GPU to do fancy things. now I'm wondering is it still bad if I discard pixels in my fragment shader?

  • Webmail with option to change password for email account?

    - by arma
    Been testing out different webmail options to use (so far AfterLogic, Horde) And it seems that there is no options to change password for user. It's really bad thing that i have to go to server and manually change passwords for users. Is there any webmail solution that will allow me to change password, that also changes on server (as client). Or is it server setting i must use before? Or it is not possible? EDIT: Note that i have cPanel host.

  • What is the SEO-recommended method for using underscores and dashes in URLs that contain geographic locations?

    - by ElHaix
    In reading through this article: In Subfolder & File Names, Use Dashes, Not Underscores Good: Good: http://www.domain.com/sub-folder/file-name.htm Bad: http://www.domain.com/sub_folder/file_name.htm In my URL's, I may have one or two city names, ending with the province/state: Burnaby_New_Westminister-BC/[some search term]. My URL rules currently are defined such that everything after the dash is the prov/state. Some geographic locations already contain dashes: Notre-Dame-de-Grâce (in QC), which I would convert to ~/Notre_Dame_de_Grace-QC/ I thought of placing the prov/state after another "/", however in some cases the province/state name may not exist, thus ~/Notre_Dame_de_Grace/, so the first term after the domain name contains the geo location {city, city_name-state}. I am now revisiting this, and wondering if this rule set should change, and if so, what is the recommended way of implementing this? -- UPDATE -- After reviewing this video, I see that I should be using the dashes, rather than underscores. However since I still want to have my geo locations in the first URL section, is there anything wrong with using a double-dash separator - ie: /city-name--state/ ?

  • Ubuntu 11.04 seem's like a laggy OS

    - by user772401
    I'm new to Linux/Ubuntu in general. I just dual booted the Ubuntu 11.04 w/Windows 7 on my Lenovo laptop - Intel i7 Quad Core 2Ghz, 4Gb ram, etc. etc... and for some reason Ubuntu is very laggy and slow. When I'm switching between programs (Chromium, folders, software center, etc..) it doesn't run as smooth as windows 7 (I have no more than 3 programs/windows up at a time...). I don't think it's my system requirements bkz Linux OSs are known to use low system resources. Could be a bad install or do people find it slow and laggy in general or is it my PC mfg type?? I installed it using Wubi - should I do a reinstall? I've already done all the recommended updates..

  • Site Directory in SharePoint 2010

    - by Enrique Lima
    Sometimes there are so many changes to the environment in which we work and live in that something will escape our attention. In discussing functionality with a client today, the topic of Site Directory came up and the comment of “well, we use it but it is too bad it is not available in 2010” was made … and huge sense of huh?!? came to me. Well, the item that escaped me came to light (and I know there are others).  So researching about it was not only an option it was/is my duty. Found an excellent post by Bill Baer on the subject.  And not only that but there is a reference to a potential and possible solution.  This is something that is being worked on through codeplex, here is the link .. http://spsitedirectory2010.codeplex.com/

  • Factory for arrays of objects in python

    - by Vorac
    Ok, the title might be a little misleading. I have a Window class that draws widgets inside itself in the constructor. The widgets are all of the same type. So I pass a list of dictionaries, which contain the parameters for each widget. This works quite nicely, but I am worried that the interface to callers is obfuscated. That is, in order to use Window, one has to study the class, construct a correct list of dictionaries, and then call the constructor with only one parameter - widgets_params. Is this good or bad design? What alternatives does the python syntax provide?

  • Pooling (Singleton) Objects Against Connection Pools

    - by kolossus
    Given the following scenario A canned enterprise application that maintains its own connection pool A homegrown client application to the enterprise app. This app is built using Spring framework, with the DAO pattern While I may have a simplistic view of this, I think the following line of thinking is sound: Having a fixed pool of DAO objects, holding on to connection objects from the pool. Clearly, the pool should be capable of scaling up (or down depending on need) and the connection objects must outnumber the DAOs by a healthy margin. Good Instantiating brand new DAOs for every request to access the enterprise app; each DAO will attempt to grab a connection from the pool and release it when it's done. Bad Since these are service objects, there will be no (mutable) state held by the objects (reduced risk of concurrency issues) I also think that with #1, there should be little to no resource contention, while in #2, there'll almost always be a DAO waiting to be serviced. Is my thinking correct and what could go wrong?

  • ubuntu 13.10 secondary monitor - doesn't redraw properly

    - by Daniel
    Hi I've just installed Ubuntu 13.10 on a Lenovo w350 and am having some issues with graphics driver. standard nouveau drivers work great on the laptop display but when I attach an external display it goes bad on the external monitor, seems it's not re-drawing properly. (Photo attached). I've tried other drivers but none of them detect the external monitor when connected. Any ideas? 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1000M] (rev a1) screenshot of effected monitor -- http://i.imgur.com/UZWMpQO.jpg UPDATE 1: I have noticed that if I leave the System Monitor open the display improves. Wierd. UPDATE 2: If I leave a video going the lag/flicker issues stop.

  • What's the difference between "Service" and "/etc/init.d/"?

    - by Marco Ceppi
    I've been managing server installations both on and off Ubuntu flavor for some time - I've become quite adjusted to /etc/init.d/ for restarting servcies. Now I get this message: root@tatooine:~# /etc/init.d/mysql status Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service mysql status Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the status(8) utility, e.g. status mysql mysql start/running, process 14048 This seems to have been brought about in the latest LTS of Ubuntu - why? What's so bad about /etc/init.d/ and what/is there a difference between service and /etc/init.d/?

  • XDIME for Mobile Applications

    - by Carlos Gavidia
    I'm involved in a project that requires to mobile-enable some previously developed Portlets. The Portlets are deployed in WebSphere Portal, and the container offers a technology called IBM Mobile Portal Accelerator that uses XDIME to render mobile pages according to the device. I'm trying to document myself in the technology and I'm having a bad time: Google only shows some outdated sites from IBM and even older posts from Volantis, another company involved in the technology (Amazon shows no related books). So... what's the current status of that technology actually? Is has some decent level of adoption?

  • It appears you are running a x server NVIDIA Drivers 304.02 Ubuntu 12.04

    - by user93444
    So I went to NVIDIA's site and I saw they had a version with a lot of bug fixes. http://www.geforce.com/drivers/results/49073 and I downloaded it, I ran the .run file rooted. It keeps saying "It appears you are running a x server" I don't have any current NVIDIA driver installed, I tried the nvidia x-config thing but that didn't work. It just says it can't be found. Should I wait until that version gets on Ubuntu's software center? I don't feel like installing their old and bad version of the drivers.

    - by SSRB
    What is the correct frequency of changing content regularly? Suppose I have a site "Seven Sea" having 5 links name as Home, About Us, Product, Sitemap, Contact Us.

A REQUEST: If this type of question already answered then give me that answered link and do not close the question.

  • Move site to new domain divided by language across subdomains

    - by mark
    I managed to find a nice domain for a fairly fledgling site of mine that actually hasn't been parked by scumbag squatters. Given the upcoming move I'm thinking I'd take the opportunity to split the content across subdomains according to language, much like wikipedia for example: current: www.old-domain.com/en/subject # English www.old-domain.com/subjecto # Spanish (default so not locale in url) proposed en.new-domain.com/subject es.new-domain.com/subjecto The advantage of doing this is a fairly competitive keyword such that I may wish to put a copy of my application on a Spanish slice in order to gain a few serp's. Also pure vanity. Google's webmaster tools allows me to move to the new domain and I can add the root domain and the subdomains but forward to only one. I'll 301 from the old domain appropriately but is there anything I should know about webmaster tools in this respect where effectively I'm moving to two addresses? (Feel free to dissuade me from doing this if it's a bad idea in comments.) I've now asked this same question on google's forums.

  • Will I get penalised by google for overflow hidden? [duplicate]

    - by Rascal Capac
    This question already has an answer here: How bad is it to use display: none in CSS? 5 answers I have 2 divs next to each other, div A and div B. Div A displays a whole wordpress post and div B displays about 15 excerpts of posts with the same tag. To get this looking nice I set the hight of div B to be the same as the hight of div A with javaScript. This means alot of post excerpts will be hidden due to overflow hidden on div B. Will Google penalise me for this, and if so, how can I make this work and still please Google? Ps. I would gladly prevent the excerpts from being indexed but the main post must be indexed Ds.

  • Visual Studio Load Tests Virtual Users Simulation

    - by Eldar
    Hello, I'm currently working on writing a load testing application that takes advantage of Load Test using Visual Studio 2010. The load test will simulate 20 users on the same machine, and I need some data to be shared in-memory between all simulated users. I was suprised I couldn't find documentation answering the following question: What seperates each virtual user's running context from the other? Does each virtual user runs the tests in its own process? Maybe in its own app domain? Or just on its own thread? I need to know because if each user is running tests in its own process then all the in-memory cache isn't shared and is created for each user instead of one time for all of them, which is bad for me.

  • Validation and Verification explanation (Boehm) - I cannot understand its point

    - by user970696
    Hopefully my last thread about V&V as I found the B.Boehm is text which I just do not understand well (likely my technical English is not that good). http://csse.usc.edu/csse/TECHRPTS/1979/usccse79-501/usccse79-501.pdf Basically he says that verification is about checking that products derived from requirements baseline must correspond to it and that deviation leads only to changes in these derived products (design, code). But he says it begins with design and ends with acceptance tests (you can check the V model inside). The thing is, I have accepted ISO12207 in terms of all testing is validation, yet it does not make any sense here. In order to be sure the product complies with requirements (acceptance test) I need to test it. Also it says that validation problems means that requirements are bad and needs to be changed - which does not happen with testing that testers do, who just checks correspondence with requirements.

  • Is it normal to sometimes take a while to get even basic things working in software development?

    - by user1092719
    This is a little hard to explain because it's a really generic question, but bear with me... I find that when I am doing or recreating basic things from scratch (i.e. without the help of libraries), sometimes it feels as though I'm taking much more time to do the task than is actually needed. I am not new to programming or development & design concepts and have worked extensively with around 9 languages and various platforms and paradigms over 5/6 years. Although I don't yet have any academic qualification for programming and have learned almost exclusively from the Internet, I have been told that the quality of my code is excellent by those with qualifications. So, I don't think I'm a bad programmer because I really love doing it and working with software architecture, but maybe I'm slow? Or is it normal to take sometimes longer than it seems necessary to do basic tasks?

  • Issues with external mounting after pysdm removed

    - by K. R. Huard
    So, I'm very new to ubuntu. I was having troubles getting my external hard drive to be read/write permission. It's owner is my macbook, and writing on the drive was repeatedly denied. In trying to sort this out, I tried the Nautilus commands (no success), installed the PYSDM application, changed some things (as suggested by this user in this forum http://askubuntu.com/a/113992 )but then found that I was getting an error message whenever I tried to mount an external storage device. The error is: Unable to mount DERPSTICK error mounting: mount exited with exit code 1: helper failed with: [mntent]: line 14 in etc/fstab is bad mount: only root can mount /dev/sdc1/ on /media/sdc1 Others with similar problems put their fstab up here, but I'm not sure how to bring it up, or if I should even try. Thanks for your time!

  • Beginner help: where to begin [closed]

    - by shad
    I want to learn how to program. A main stream programming language such as Java, C++/C# is my primary target. Currently, I am a high school student planning to take programming, Digital electronics courses next semester. My biggest problem is that I do not know where to start and I have no one to consult with. Should I take a course at my local community college this summer? Get some books or try learning from some internet websites? What would be the best option a book or website? note that this is no longer my words, but rather ChrisF's because he decided to reword the question a bit (bad) and spaced it out better (good).

  • I Can't install Skype on Ubuntu 12.04 x64. Can someone help me?

    - by Matheus
    I'm having a trouble when trying to install Skype on my Ubuntu 12.04.1 x64. My notebook have compatible hardware with Ubuntu. My previous OS installed on this machine was the Ubuntu 12.04 x64 and Skype was working great, but I got a formatation and I installed the New ubuntu 12.04.1.

I tried install the .deb package from the official Skype site, but I got the same error! Any Help? Sorry about my bad English, I'm Brazilian

  • Should I create an Enum mapping to my database table

    - by CrazyHorse
    I have a database table containing a list of systems relevant to the tool I am building, mostly in-house applications, or third-party systems we receive data from. This table is added to infrequently, approx every 2 months. One of these systems is Windows itself, which is where we store our users' LANs, and I now need to explicitly reference the ID relating to Windows to query for user name, team etc. I know it would be bad practice to embed the ID itself into the code, so my question is what would be the best way to avoid this? I'm assuming my options are: create a global constant representing this ID create a global enum containing all systems now create a global enum and add systems to it as & when they are required in the code retrieve the ID from the database based on system name I appreciate this may seem a trivial question, but I am going to have many situations like this during the course of this build, and although we are in complete control of the database I would like to conform to best practice as far as possible. Many thanks!
