  • Implementing cache system in Java Web Application

    - by TGM
    I worked with JPA (Eclipselink implementation) and Hibernate. As I understand these two have great caching systems. I am interested in caching in a Web application and in order to better understand the process I'm trying to implement something on my own. Sadly, I cannot find any in depth documentation about this subject. I'm interested in things like high scalability, sharing memory on different machines and other important theoretical matters. Is there any tutorial or open project I could check out? Thank you! *LE: * I want to cache DB information in POJOs just like JPA or Eclipselink

  • 1. Rename computer 2. Add this computer

    - by user91583
    I've followed the instructions but they haven't worked. How do I -1. Rename this computer as it would appear in: -a Ubuntu One Preferences -- Devices; and [next line] -b https://one.ubuntu.com/account/ -- Devices -2. Your https://one.ubuntu.com/help/tutorial/install-and-setup-ubuntu-one-8/ says After you sign in to Ubuntu One via your web browser you should see the Add this Computer button. I am on the unfortunate side of that 'should'. There is no Add this Computer button.

  • What can I do to make my eService website customers feel it is a luxurious service? [closed]

    - by Farshid
    I'm developing an e-service website that its monetization model is via paid membership. Beside quality service and content, because I'm serving them for a high fee, I want to make them feel like it is a personal, unparalleled kind of service and I want to spend money for creating things that I give them after their registration such as a beautiful physical membership card so that I can use the effect of mouth-words better and beside that let them be proud about the service. I've tried my best to develop the site experience classy and I'm looking for things in real world to send them after their registration (such as membership card and a small paper tutorial). What are your suggestions? Have you seen things like this before that a website sends you some physical things for making you more loyal and/or something like that? Please kindly share your experiences/suggestions.

  • Hosting a website with Windows Azure

    - by Rev
    I may be completely misunderstanding what Azure is but is it possible for me to host a basic website on Windows Azure? I have a site that I've built in HTML and CSS that I'd like to upload to Azure but I can't figure out any way to do this. The site claims I can use it for web hosting, but if I can't FTP then I'm not sure how to do this. Is there a simple tutorial somewhere? I couldn't find anything close to what I'm looking for through searching.

  • Are there any free embedable REPL interpreters for a website? [migrated]

    - by Google
    I am hoping to find a free REPL interpreter for a number of languages. I am starting a new web page to help developers learn with a number of tutorials. I want to embed an interpreter on the site so users can have a tutorial and interpreter side by side. I really like free interpreters such as the one at repl.it. However, I am unable to find a free/embeddable interpreter. I was hoping to avoid making one myself-- they seem tricky to make safely! Thanks!

  • Ubuntu 13.10 on SSD (system) and HDD (data). Missing /grub/i386-pc/normal.mod

    - by Tatarkow
    I've got HDD (750 GB) and SSD (16 GB). I want to install Ubuntu (13.10) on SSD, but because of its smallness I need to install /home, /var and /tmp on HDD. After that I would like to install Windows (system + data) on another partition of that HDD, but it is not important now. I installed Ubuntu (I had formatted and partitioned the disk before), but when I restarted my laptop it said: 'error: file '/grub/i386-pc/normal.mod' not found. grub rescue'. I tried to reinstall Grub 2 using this tutorial (as sdXY I used sdb1, because it's the only one partion of my SSD), but it didn't work. Can anybody help me, please? Thanks, Tatarkow

  • Either I'm not confident I just don't know anything [on hold]

    - by zoomerzoom25
    My name is Sael and I'm 14 years old. Since I was 12 and I got my first computer I instantly go interested in making games. So of course like any other I googled it, got discouraged and forgot about it for a few months. When I was 13 I decided to continue programming, and decided that java would best suit me. Now after a year, I have a basic understanding of java and how it works (it just clicked instantly one day). Anyways, my problem is that I know how I'm going to make a simple game in my head, but as soon as I click that "New Project" button on eclipse, I'm instantly lost and can't figure out where to start. I can't do much without a tutorial beside me since my mind is so dependent on it. So here's the question : what can I do to get past this problem of mine, and have any of you felt like this before? sorry if my English is a bit incorrect, Spanish is my main language* I've made Minecraft mods before

  • How to use GWT 2.1 Data Presentation Widgets

    - by Caffeine Coma
    At the 2010 Google IO it was announced that GWT 2.1 would include new Data Presentation Widgets. 2.1M is available for download, and presumably the widgets are included, but no documentation has yet surfaced. Is there a short tutorial or example for how to use them? I've seen a rumor that CellList and CellTable are the classes in question. The Javadoc for them is riddled with lots of TODOs, so quite a bit is still missing in terms of usage.
