  • Which Java web framework do you recommend for intranet webapp (not content website)?

    - by pregzt
    I'm about to start development of small purpose build intranet web application for small software vendor. It will be administration console of the server managing licenses for off-the-shelf software installed by users. There will be a few users who need to be able to sign in, issue a batch of license codes, revoke some, renew outdated, resolve issues, etc. Bear in mind that my customer requires Java for this solution. I'm seasoned Java programmer and before I used different frameworks to implement webapps, mainly Apache Struts in the past and Spring MVC recently. I was wondering what else could you recommend for such specific intranet webapp. I looked at using Google Web Toolkit (possibly with SmartGWT) Ext JS for fancy widgets in UI and REST back-end in SpringMVC SpringMVC with JQueryUI Could you please think of any piece of recommendation with regard to the choice I'm going to made?

  • Microsoft Discontinuing Windows Home Server

    - by Jason Fitzpatrick
    As part of their ongoing push to simplify their product lineups, Microsoft is discontinuing their popular small office/home server platform Windows Home Server. On to see the new alternative for small volume users. Although, in the context of the simplification push, it shouldn’t seem surprising, many people were in fact surprised by Microsoft’s move to drop the extremely popular and economical WHS platform. Now, instead of dropping $99 on a copy of WHS to build their simple home servers users will find themselves on the first tier of the new Windows Server 2012 pricing ladder: a copy of Essentials for $425. There is one version below Essentials, Foundation, but it’s currently OEM only. Hit up the link below to see the new features and pricing structure of Windows Server 2012.

  • Where can I get a cheap database, no web hosting needed

    - by PhilipK
    I'm building an application which requires a fairly small online MySQL database. I don't need any web hosting. What are some cheap options for an online database? *Edit(a bit more about what I'll be using it for) The database itself is very small it contains market statistics for 5 weeks of time. Once a week the data will be updated, so that it always contains the most recent 5 weeks. Then I will use the data in that to create an XML file which is generated with PHP. The XML file will need to be accessed hundreds-thousands of times per month.*

  • Elementary OS boots to a terminal (other OS) [on hold]

    - by Benjamin Watson
    Im new to this site, please forgive me if I missed some posting protocol of some sort. I am attempting to install Luna on my samsung s2 laptop (a8 amd radeon 7640g) and when I click on try luna, it just pulls up a terminal after the insignia (curvy E). When I install it, same issue.

  • Firefox clones for Ubuntu

    - by cipricus
    In Windows I use, beside the main Firefox installation, one or even two "Firefox clones" for different purposes (specifically oriented addons and configurations, light configuration without addons, configuration for a different user, etc). A clone of Firefox is a browser that is identical to Firefox except the name. (It may have more - but not less - features than FF and it must be installable beside Firefox, not on top/instead of it. So, a clone is not a replacement/exclusive alternative of FF: in the way Swiftfox is, taking all previous Firefox extensions and configuration.) For example, in Windows, Pale Moon, Cometbird and Wyzo are FF clones (but they do not have Linux support). Basically, Flock browser would also qualify, and it had support for Linux: but it was discontinued. What remains as closest to being a full clone is Seamonkey, has support for Linux, but it is not a complete clone (although it can use a lot of FF extensions): themes are not working, the interface is in general different and rather primitive. It has the merit of keeping the pace with FF 4+ (in contrast with Swiftweasel, for example.) Are such more browsers available in Ubuntu? (As for comments asking why I "really" need these clones, I am just used to doing that, I like two separate Firefox-like browsers: why pleasure, just like curiosity, would not be enough??)

  • Are there any companies using BDD in a .NET environment?

    - by Nick
    I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily. I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'. Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD. I have two questions really: Is BDD adopted by companies out there? Who are they? How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?

  • Ubuntu won't boot after initializing the Build Environment for Android

    - by EntryLevelDev
    My laptop worked perfectly util I initialized the build environment for Android. The GUI won't start. It looks like some kinds of graphics card problems. I tried to fix it but after trying a lot of solutions on the internet nothing worked. (I only know basic linux stuffs.) I've already reinstalled the OS. However, I still want to build the Android from source. Any idea what might cause the problem? any workaround? Here is the command that I used to initialize the build environment: $ sudo apt-get install git gnupg flex bison gperf build-essential \ zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \ libgl1-mesa-dev g++-multilib mingw32 tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386 $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so My laptop model is asus u36sd. (https://help.ubuntu.com/community/Asus_U36SD) Thanks Edit: Base on this, I guess libgl1-mesa-glx:i386 might cause the issue. sudo apt-get install libgl1-mesa-dri:i386 The following packages will be REMOVED: libgl1-mesa-dri-lts-quantal libxatracker1-lts-quantal ubuntu-desktop xorg xserver-xorg-lts-quantal xserver-xorg-video-all-lts-quantal xserver-xorg-video-vmware-lts-quantal The following NEW packages will be installed: libdrm-intel1:i386 libdrm-nouveau1a:i386 libdrm-radeon1:i386 libdrm2:i386 libexpat1:i386 libffi6:i386 libgl1-mesa-dri:i386 libllvm3.0:i386 libpciaccess0:i386 libstdc++6:i386

  • can Snort be installed on VPS?

    - by jack
    Hi Linux Admins I want the maximum security for my linux vps. I found many tutorials round the net but it doesn't cover the Snort. Only those like portentry, logsentry, tripwire and so on. So I'm beginning to think that Snort is not appropriate for a linux host. I think it's suitable only as a proxy/middle-man that checks traffic before passing to acutual targets. I'd like to whether Snort can be installed on VPS which serves typical servers like web/mail. Can Snort be in complict with OSSEC which I think it doesn't check the traffic but the log files only for Intrusion Detection/Anomaly? Thank you.

  • How to design a replay system

    - by daddz
    So how would I design a replay system? You may know it from certain games like Warcraft 3 or Starcraft where you can watch the game again after it has been played already. You end up with a relatively small replay file. So my questions are: How to save the data? (custom format?) (small filesize) What shall be saved? How to make it generic so it can be used in other games to record a time period (and not a complete match for example)? Make it possible to forward and rewind (WC3 couldn't rewind as far as I remember)

    - by Gilberto Albino
    there! I am scared here! I am a Windows 7 User and decided to install Ubuntu 12.04 on my Notebook Dell Inspiron N5110 and when the Grub loads with the menu list the fan starts speeding up. If I choose windows the fan is noiseless but if I choose Ubuntu... Gosh!!! It continues speeding up and overheating... I'm very sad about that! Every time I try to use Linux... I get a diferent hardware issue related to incompatibility or bugs! When it's not graphic driver it is bug elsewhere unimaginable!!! If there is a solution for this... I wonder if someone could spend some time helping me out because... I have JUST bought this notebook because it is in the list of Certified Hardware: http://www.ubuntu.com/certification/hardware/201012-6931/ So this is sad and somehow disgusting! Linux is going for the wrong way! It's never gonna be popular while doesn't have so wide hardware support like WIndows! That's a pitty! It's very likely I won't get answered meanwhile I will switch back for windows! I prefer paying my Windows License and having a fully working system than having a free open source software that is about to explode my notebook or toast my hands before! So you linux wonderful guys help! I need somebody help (beattles so I won't cry)

  • format/build raid 5 with one 4k drive, three 512b

    I have 4 WD 1TB drives which I want to 4x1TB Raid5. I am not sure what course of action to take next. How do I configure my 4th drive (sde) to align with the rest? Will this affect performance?

  • Recurring lsb-release and Software Center glitch after installing MATE

    - by infomorph
    I just recently upgraded to Ubuntu 11.10. Not a fan of Unity, so I decided to try out the MATE desktop from Linux Mint. I added the Mint repository, grabbed and installed the MATE packages, and got rid of the repo so I wouldn't be downloading any other Mint packages. I did have some glitches with the packages (missing dependency stuff), but I fixed it. As other users have reported, installing MATE temporarily breaks the Ubuntu Software Center because lsb_release shows the machine as Linux Mint rather than Ubuntu. I can fix it as noted in this answer by editing /etc/*release and /etc/*issue. Problem is, this only works until I reboot the machine. Every time I reboot, /etc/lsb-release and /etc/issue revert to Linux Mint, breaking Software Center again until I edit them, again. Can anyone help me pin down what keeps changing these files? Much appreciated, thanks. Rephrasing the crux of the problem: where do /etc/lsb-release and /etc/issue get their info from? What would cause them to be revised on reboot?

  • What are unique aspects of a software Lifecycle of an attack/tool on a software vulnerability?

    - by David Kaczynski
    At my local university, there is a small student computing club of about 20 students. The club has several small teams with specific areas of focus, such as mobile development, robotics, game development, and hacking / security. I am introducing some basic agile development concepts to a couple of the teams, such as user stories, estimating complexity of tasks, and continuous integration for version control and automated builds/testing. I am familiar with some basic development life-cycles, such as waterfall, spiral, RUP, agile, etc., but I am wondering if there is such a thing as a software development life-cycle for hacking / breaching security. Surely, hackers are writing computer code, but what is the life-cycle of that code? I don't think that they would be too concerned with maintenance, as once the breach has been found and patched, the code that exploited that breach is useless. I imagine the life-cycle would be something like: Find gap in security Exploit gap in security Procure payload Utilize payload What kind of differences (if any) are there for the development life-cycle of software when the purpose of the product is to breach security?

  • Object Oriented programming on 8-bit MCU Case Study

    - by Calvin Grier
    I see that there's a lot of questions related to OO Programming here. I'm actually trying to find a specific resource related to embedded OO approaches for an 8 bit MCU. Several years back (maybe 6) I was looking for material related to Object Oriented programming for resource constrained 8051 microprocessors. I found an article/website with a case history of a design group that used a very small RAM part, and implemented many Object based constructs during their C design and development. I believe it was an 8051. The project was a success, and managed to stay inside the very small ROM/RAM they had available. I'm attempting to find it again, but Google can't locate it. The article was well written, and recommended a "mixed" approach using C methods for inheritance and encapsulation - if I recall correctly. Can anyone help me locate this article?
