  • How can I distribute a unique database already in production?

    - by JVerstry
    Let's assume a successful web Spring application running on a MySQL or PostgreSQL database. The traffic is becoming so high and the amount of data is becoming so big that a distributed database solution needs to be implemented to address scalability issue. Let's also assume this application is using Hibernate and the data access layer is cleanly separated with DAOs. Ideally, one should be able to add or remove databases easily. A failback solution is welcome too. What would be the best strategy to scale this database? Is it possible to minimize sharding code (Shard) in the application?

  • Sandboxes Explained: How They’re Already Protecting You and How to Sandbox Any Program

    - by Chris Hoffman
    Sandboxing is an important security technique that isolates programs, preventing malicious or malfunctioning programs from damaging or snooping on the rest of your computer. The software you use is already sandboxing much of the code you run every day. You can also create sandboxes of your own to test or analyze software in a protected environment where it won’t be able to do any damage to the rest of your system.

    - by Phobia
    Okay, so I'm a java developer (or at least I think I am),and also a student at the same time I want to get a job when I graduate,I'll be graduating in a year or so (hopefully) (Note: my major has nothing to do with programming) Now, I'm between a rock and a hard place I also want to nail the foundations to become a good software developer. I want to be able to write programs that solve problems,not just glue code The software market in my country for java developers is just a few developers working with Java EE (struts,spring,hibernate....etc) I'm currently learning C++ with this book. I've also watched most of the 1st lecture of this course and I understood pretty much everything I watched To sum it up, I have three options Learn Java EE Learn C++ Learn Scheme Which is better for me at this point?

  • Should we use an outside CMS?

    - by SomeKittens
    I work at a web design/development shop. Everything we do is centered around the Joomla! CMS. I'm a bit worried-if anything goes wrong with Joomla (major security flaw revealed, Joomla folds and ceases development) we're sunk. I'm meeting with the CEO to plan the next few steps for our company. Should I recommend that we create our own in-house CMS or am I just being paranoid about a single point of failure?

  • Managing Joomla via Android

    Surprisingly, it was only today that I actually looked for possible solutions to write more content for my blog. Since quite some time I'm using my Samsung Galaxy Tab 10.1 for all kind of social media activities like Google+, FB, etc. but also for my casual mail during the evening hours. And yes, I feel a little bit guilty about missing the chance to use my tablet to write some content here... OK, only a little bit. ;-) These are not the droids you are looking for But those lazy times are over! While searching the Play Store with the expression 'joomla' I got three interesting hits: - Joomla Admin Mobile! - Joooid - Joomla! Security Checklist After reading the reviews I installed the two later apps. Joomla! Security Checklist The author clearly outlines here that the app is primarily for his personal purpose to have safety checklist at hand at anytime. I guess that any reader of this article has an Android based smartphone or tablet, so that simple app should be part of your toolbox when using Joomla! for your websites. Joooid plugin & app Although I was looking for an app that could work with the default XML RPC interface of Joomla I have to admit that this combination of an enhanced Web service suits me better, mainly due to performance reason. The official website has not only the downloads for Joomla versions 1.5 - 2.5 but also very good and easy to follow step-by-step instructions to prepare your server for the Android app. It will take you less than 5 minutes to get it up and running. For safety reasons, I recommend that you should configure your Web server to have an additional authentication layer on the plugins folder. The smartphone app has the ability to run against HTTP authentication. Personally, I like the look and feel of the app. It is a little bit different compared to the web UI but still easy to use. In fact, this article is the first one written in the Joooid app. At the moment, I only miss the ability to have list tags. Quick and easy Writing full-fledged articles with images, a couple of hyperlinks and some styling here and there should be left to the desktop. At least for the moment. Let's see whether I'm going to change my mind on this during the upcoming months... I'll give it a try, and hope to publish at least once per month to write some content using Joooid. Actually, it would be great to have some feedback about other Joomla! clients in the wild.

  • Are there any concerns with using a static read-only unit of work so that it behaves like a cache?

    - by Rowan Freeman
    Related question: How do I cache data that rarely changes? I'm making an ASP.NET MVC4 application. On every request the security details about the user will need to be checked with the area/controller/action that they are accessing to see if they are allowed to view it. The security information is stored in the database. For example: User Permission UserPermission Action ActionPermission A "Permission" is a token that is applied to an MVC action to indicate that the token is required in order to access the action. Once a user is given the permission (via the UserPermission table) then they have the token and can therefore access the action. I've been looking in to how to cache this data (since it rarely changes) so that I'm only querying in-memory data and not hitting a database (which is a considerable performance hit at the moment). I've tried storing things in lists, using a caching provider but I either run in to problems or performance doesn't improve. One problem that I constantly run in to is that I'm using lazy loading and dynamic proxies with EntityFramework. This means that even if I ToList() everything and store them somewhere static, the relationships are never populated. For example, User.Permissions is an ICollection but it's always null. I don't want to Include() everything because I'm trying to keep things simple and generic (and easy to modify). One thing I know is that an EntityFramework DbContext is a unit of work that acts with 1st-level caching. That is, for the duration of the unit of work, everything that is accessed is cached in memory. I want to create a read-only DbContext that will exist indefinitely and will only be used to read about permission data. Upon testing this it worked perfectly; my page load times went from 200ms+ to 20ms. I can easily force the data to refresh at certain intervals or simply leave it to refresh when the application pool is recycled. Basically it will behave like a cache. Note that the rest of the application will interact with other contexts that exist per request as normal. Is there any disadvantage to this approach? Could I be doing something different?

  • How to auto-unlock Keyring Manager in 12.10?

    - by Torben Gundtofte-Bruun
    How can I auto-unlock the Keyring Manager in 12.10? This answer for 11.10 doesn't seem to apply because the Keyring Manager looks different in 12.10 so I can't follow the instructions. I have set up my machine to automatically log in to my account. I don't mind the lesser security of having the keyring automatically unlocked. (This is still a home desktop computer of a simple user, not a missile launch system.)

    This question I am asking because I couldn't find any source which gives complete overview of java development. I just want to know where java technology currently in market & what is preferable for development ! Java always remain top programming language for development point of view. However, java is combo of, j2ee, j2me, jsp, jsf, spring, other frameworks, ui components, jndi, networking tools and various other "J" are there ! However, learning java is definitely dependent on the development requirement, but still, to be a well-experienced java developer, what is the organised way of learning java? What is preferable in current technology ? and what is deprecated, currently ?

  • Survey: Your Plans for Adopting New Firefox Releases?

    - by Steven Chan (Oracle Development)
    Mozilla is committing to releasing new Firefox versions every six weeks.  Mozilla released Firefox 5 this week.  With this release, Mozilla states that Firefox 4 is End-of-Life and will not receive any additional security updates.  In a comment thread posted on to a Mike Kaply's blog article discussing these new Firefox policies, Asa Dotzler from Mozilla stated: ... Enterprise has never been (and I’ll argue, shouldn’t be) a focus of ours. Until we run out of people who don’t have sysadmins and enterprise deployment teams looking out for them, I can’t imagine why we’d focus at all on the kinds of environments you care so much about.  In a later comment, he added: ... A minute spent making a corporate user happy can better be spent making many regular users happy. I’d much rather Mozilla spending its limited resources looking out for the billions of users that don’t have enterprise support systems already taking care of them. Asa then confirmed that every new Firefox release will put the previous one into End-of-Life: As for John’s concern, “By the time I validate Firefox 5, what guarantee would I have that Firefox 5 won’t go EOL when Firefox 6 is released?” He has the opposite of guarantees that won’t happen. He has my promise that it will happen. Firefox 6 will be the EOL of Firefox 5. And Firefox 7 will be the EOL for Firefox 6.  He added: “You’re basically saying you don’t care about corporations.” Yes, I’m basically saying that I don’t care about making Firefox enterprise friendly. Kev Needham, Channel Manager at Mozilla later stated to PC Mag: The Web and Web browsers continue to evolve rapidly. Mozilla's focus is on providing users with the best Web experience possible, and Firefox needs to evolve at the pace the Web's users and developers expect. By releasing small, focused updates more often, we are able to deliver improved security and stability even as we introduce new features, which is better for our users, and for the Web.We recognize that this shift may not be compatible with a large organization's IT Policy and understand that it is challenging to organizations that have effort-intensive certification polices. However, our development process is geared toward delivering products that support the Web as it is today, while innovating and building future Web capabilities. Tying Firefox product development to an organizational process we do not control would make it difficult for us to continue to innovate for our users and the betterment of the Web.  Your feedback needed for E-Business Suite certifications  Mozilla's new support policy has significant implications for enterprise users of Firefox with Oracle E-Business Suite.  We are reviewing the implications for our certification and support policies for Firefox now.  It would be very helpful if you could let me know about your organisation's plans for Firefox in light of this new information.  Please feel free to drop me a private email, or post a comment here if that's appropriate.

  • Are the technologies used in an application part of the architecture, or do they represent implementation/detailed design details?

    - by m3th0dman
    When designing and writing documentation for a project an architecture needs to be clearly defined: what are the high-level modules of the system, what are their responsibilities, how do they communicate with each other, what protocols are used etc. But in this list, should the concrete technologies be specified or this is actually an implementation detail and need to be specified at a lower level? For example, consider a distributed application that has two modules which communicate asynchronously via AMQP protocol, mediated by a message broker. The fact that these modules use the Spring AMQP library for sending and receiving messages is a fact that needs to be specified in the architecture or is a lower-level detailed design/implementation detail?

  • it is a good approach to implement dependency injection in a desktop app?

    - by luis_laurent
    Well, the thing is that I am just about to create a Desktop App (with .NET windows forms) And now I just wonder if it would be really a wise choise to use any IoC (StructureMap,Ninject,Spring .Net), I have used them before for Asp.Net web applications but what makes me doubt now is the fact that working with windows forms my business entities will persist when I navigate through tabs and unlike than web forms or mvc apps where it would be necesary to inject my business entity for every new request that is performed, I mean this because of the Asp.Net page life cycle where is performed the initialization and controls instantiation. Maybe I am misunderstanding the point of using an IoC, so please tell me what do you think would be a better choise?
