  • Need some help on tomcat URL mod_rewrite or mod_jk

    - by Redbull Fan
    I am trying to remove the context name from the url of my server. Current URL - http://www.domainname.com/MyApp/ What I need to make is to make it avaialble at - www.domainname.com/ So it is only going to host one main app and that needs to be displayed when we open www.domainname.com/ on browser. I have already tried couple of things like below - RewriteEngine On RewriteCond %{REQUEST_URI} !^/(Context/.*)$ RewriteRule ^/(.*)$ /Context/$1 [P,L] OR redirect permanent /MyApp/ abcd://domainname.com OR Using JKMount - JkMount /MyApp/* ajp13 JkMount /MyApp* ajp13 OR Deploy war file to ROOT of tomcat and make relevant chagnes in web and server.xml All of these aren't working and I keep getting a intenal error. I need a way to basically trim the tomcat URL to make short. Thanks, Andy

  • Where to contribute a Mozilla Persona example?

    - by Serg
    I found out about Mozilla Persona today and fell in love with it completely. It really does feel like the future of account management. For the first time ever, I actually want to contribute to open source because I believe in this tech. I wrote a simple ASP.Net MVC3 demo web application showing how to login and logout users using Persona. I want devs in my language ecosystem to have a simple time learning about this by reading example code. Here is the repository: https://github.com/sergiotapia/ASP.Net-MVC3-Persona-Demo Where do I contribute this link to my repository so it's easily found? Any suggestions? It's my first time releasing code for a "big project" so to speak.

  • big lie about programmer [closed]

    - by gcc
    About computer engineering/ computer science, Can you give me big lie ? ex : - There is no need to attend school ( study computer engineering ). Because every one can code ( write program ) - Programmer cannot do web design , they can only write code - there are no difference between software engineer and coder EDIT: A lie is a type of deception in the form of an untruthful statement, especially with the intention to deceive others. Why someone try to deceive other people especially customer ? I think they try to prove they are real computer engineer without having diploma in computer science. If you look in that manner to my answer you can easily understand what I want

  • PHP 5.2 et 5.3 : un bug étrange rend les attaques par Déni de Service enfantine sous Windows et Linux

    PHP : un bug étrange rendrait enfantines les attaques par Déni de Service Il toucherait les versions 5.2 et 5.3 du langage sous Windows et Linux Un bug critique vient d'être découvert dans les branches 5.2 et 5.3 de PHP, le langage de programmation Web parmi les plus populaires. Ce bug est provoqué par certaines valeurs de chiffres à virgule flottante ayant un nombre considérable de décimaux. Leurs calculs ou évaluations en PHP provoqueraient une boucle infinie occupant 100% des ressources du CPU. L'exécution de la ligne de code suivante, ou même son équivalent sans la notation scientifique (avec 324 décimales), provoquerait donc le plantage de la machine, et ce sou...

  • My self-generated CA is nearing it's end-of-life; what are the best practices for CA-rollover?

    - by Alphager
    Some buddies and me banded together to rent a small server to use for email, web-hosting and jabber. Early on we decided to generate our own Certificate Authority(CA) and sign all our certificates with that CA. It worked great! However, the original CA-cert is nearing it's end-of-life (it expires in five months). Obviously, we will have to generate a new cert and install it on all our computers. Are there any best practices we should follow? We have to re-generate all certs and sign them with the new CA, right?

  • Redesigning foreign website for my portfolio and offer it?

    - by BeatMe
    Hi, I've had an interest in web design for a long time and am constantly trying to learn something new. I do not have any references in my portfolio, but would like to start freelancing. Is it bad practice to redesign a website from a local company and use it for my portfolio? Do I infringe any copyright? What if I offer the redesign to the company? Has someone done this before? If so, share your experiences.

  • How to make creating viewmodels at runtime less painfull

    - by Mr Happy
    I apologize for the long question, it reads a bit as a rant, but I promise it's not! I've summarized my question(s) below In the MVC world, things are straightforward. The Model has state, the View shows the Model, and the Controller does stuff to/with the Model (basically), a controller has no state. To do stuff the Controller has some dependencies on web services, repository, the lot. When you instantiate a controller you care about supplying those dependencies, nothing else. When you execute an action (method on Controller), you use those dependencies to retrieve or update the Model or calling some other domain service. If there's any context, say like some user wants to see the details of a particular item, you pass the Id of that item as parameter to the Action. Nowhere in the Controller is there any reference to any state. So far so good. Enter MVVM. I love WPF, I love data binding. I love frameworks that make data binding to ViewModels even easier (using Caliburn Micro a.t.m.). I feel things are less straightforward in this world though. Let's do the exercise again: the Model has state, the View shows the ViewModel, and the ViewModel does stuff to/with the Model (basically), a ViewModel does have state! (to clarify; maybe it delegates all the properties to one or more Models, but that means it must have a reference to the model one way or another, which is state in itself) To do stuff the ViewModel has some dependencies on web services, repository, the lot. When you instantiate a ViewModel you care about supplying those dependencies, but also the state. And this, ladies and gentlemen, annoys me to no end. Whenever you need to instantiate a ProductDetailsViewModel from the ProductSearchViewModel (from which you called the ProductSearchWebService which in turn returned IEnumerable<ProductDTO>, everybody still with me?), you can do one of these things: call new ProductDetailsViewModel(productDTO, _shoppingCartWebService /* dependcy */);, this is bad, imagine 3 more dependencies, this means the ProductSearchViewModel needs to take on those dependencies as well. Also changing the constructor is painfull. call _myInjectedProductDetailsViewModelFactory.Create().Initialize(productDTO);, the factory is just a Func, they are easily generated by most IoC frameworks. I think this is bad because Init methods are a leaky abstraction. You also can't use the readonly keyword for fields that are set in the Init method. I'm sure there are a few more reasons. call _myInjectedProductDetailsViewModelAbstractFactory.Create(productDTO); So... this is the pattern (abstract factory) that is usually recommended for this type of problem. I though it was genious since it satisfies my craving for static typing, until I actually started using it. The amount of boilerplate code is I think too much (you know, apart from the ridiculous variable names I get use). For each ViewModel that needs runtime parameters you'll get two extra files (factory interface and implementation), and you need to type the non-runtime dependencies like 4 extra times. And each time the dependencies change, you get to change it in the factory as well. It feels like I don't even use an DI container anymore. (I think Castle Windsor has some kind of solution for this [with it's own drawbacks, correct me if I'm wrong]). do something with anonymous types or dictionary. I like my static typing. So, yeah. Mixing state and behavior in this way creates a problem which don't exist at all in MVC. And I feel like there currently isn't a really adequate solution for this problem. Now I'd like to observe some things: People actually use MVVM. So they either don't care about all of the above, or they have some brilliant other solution. I haven't found an indepth example of MVVM with WPF. For example, the NDDD-sample project immensely helped me understand some DDD concepts. I'd really like it if someone could point me in the direction of something similar for MVVM/WPF. Maybe I'm doing MVVM all wrong and I should turn my design upside down. Maybe I shouldn't have this problem at all. Well I know other people have asked the same question so I think I'm not the only one. To summarize Am I correct to conclude that having the ViewModel being an integration point for both state and behavior is the reason for some difficulties with the MVVM pattern as a whole? Is using the abstract factory pattern the only/best way to instantiate a ViewModel in a statically typed way? Is there something like an in depth reference implementation available? Is having a lot of ViewModels with both state/behavior a design smell?

  • How to configure ubuntu for lightweight low-memory usage?

    - by augustin
    I just upgraded an old, secondary computer to the latest Kubuntu (10.10). It seems the effort was a bit too much for the hardware and one 512MB memory module died. I tried to take it away, clean the connectors, put it back several times, but to no avail. Until such a time I can find a second hand DDR memory module, I am left with a meagre 256MB RAM, which is below the official requirements (384MB) to run Kubuntu/KDE. Indeed: the computer constantly swaps the memory, making everything painfully slow. Since Kubuntu is already installed and I use it on all my computers (and I want to keep KDE for when I really need it), how can I configure ubuntu to squeeze out every bit of unnecessary memory usage? This is a secondary computer but still very useful. We use it mostly for web browsing. A "lightweight" tag is missing.

  • Effective way of keeping past projects with their working development environment?

    - by Korey Hinton
    I find that whenever I want to go run a past project, it will take a long time before I can find it and before I have everything set-up again for it to be able to run. For example, I have python projects I created in Linux, and it depends on software packages that are easily installed in Linux, yet I no longer have the Linux VM I was using. And some of my other projects depend on other variables like web server configuration, PATH variables, sdk, IDE, OS version, device, etc. Does someone have an effective way of handling this issue? As of now I have only concerned myself with keeping the source code backed up yet it is difficult re-establish the working development environment and it is also difficult to keep the working development environment around as well.

  • How important is to avoid name collisions between libraries belonging to different domains?

    - by Sergio
    I have written a small open source Java library for facilitating conversions between different types of objects (in the style of Google's gson, but quite more general). It seems to me that a nice natural name for my library is JConverter, after browsing in the web to see if another library with the same name already exists, I found a library with the same name for Joomla. My concrete question is: How important is to avoid naming collisions when creating an open source library if an existing library with the chosen name already exists in a complete different domain ? (in my concrete case, these are libraries even implemented for different languages).

  • Facebook Java API

    - by Filippo
    I'd like to write a program in java (not a servlet, not jsp, not a webapp) which allows me to do simple things, such as connecting to a FB account and retrieve the status or posts on the wall. I know facebook no longer supports official JavaAPI, so I was wondering what are the best (and most simple, being the program very basic) unofficial api out there. If possible, i would also like some example-code. searching through the web, I've read that you need two secret keys to create a facebook application, and I have not a fb account. Is it indispensable to have an account? thank you everyone

  • How often do you use google, to answer programming relatated questions? [closed]

    - by Mercfh
    I hope this isn't too subjective, but it is programming related and Im curious. Alot of times I feel.......dumb for lack of a better word when I have to look something up. Alot of times I forget all the specificity of a language and have to look up something like "Doing XXX in C++" for instance, or something along the lines of that. How often do you guys as Programmers both Professionally and On your own have to use google to look up something. Or do most people just kind of remember these things. I guess what Im really asking is, do you often have to use google or other web-search sites to remember how to do what is seemingly "simple" things with languages but you've just forgotten? Please tell me im not the ONLY one.

  • One Week on New Servers and Everything is Great

    - by Jeff Julian
    It has been a week since we moved our Geekswithblogs.net System to a new set of load balanced servers and everything has been going great.  I am so amazed at the performance of the new hardware.  On average, we only use less than 5% of the CPU at any given moments or the database and web servers.  I have seen a performance boost in page load as well, but I will have to confirm that with the statistics as they roll in.  This is all in preparation for a new community we are launching with some friends that we will be announcing shortly.  We will be launching a nice little contest for our bloggers as well.

  • Education path advice

    - by Miroslav Zadravec
    I'm thinking of continuing my education and going for masters degree. I must decide between two programs. One is CS/IT and focuses on algorithms, math, multimedia, web technologies with optional interesting courses like AI and robotics. Second is about business process management, software architecture and project management. I have some experience in business software and I must say, I never though I need deeper understating of algorithms or program language but I always felt that I'm lacking in project planing or management knowledge. On the other side, CS/IT looks more interesting but what are the chances to find a job that require such skills?

  • SAML Request / Response decoding.

    - by Shawn Cicoria
    When you’re working with Web SSO integration, sometimes it’s helpful to be able to decode the tokens that get passed around via the browser from the various participants in the trust – RP, STS, etc. With SAML tokens, sometimes they’re simply base64 encoded when they’re in the POST body; other times they’re part of the query string, which they end up being base64encoded, deflated, then Url encoded. I always end up putting together some simple tool that does this for me – so, this is an effort to make this more permanent. It’s a simple WinForms application that is using NetFx 4.0. Download

  • Point me to info about constructing filters (of lists)

    - by jah
    I would like some pointers to information which would help me understand how to go about providing the ability to filter a list of entities by their attributes as well as by attributes of related entities. As an example, imagine a web app which provides order management of some kind. Orders and related entities are stored in a relational database. And imagine that the app has an interface which lists the orders. The problem is: how does one allow the list to be filtered by, for example:- order number (an attribute) line item name (an attribute of a n-n related entity) some text in an administrative note related to the order (text found in an attribute of a 1-1 related entity) I'm trying to discover whether there is something like a standard, efficient way to construct the queries and the filtering form; or some possible strategies; or any theory on the topic; or some example code. My google foo fails me.
