  • Is possible to create an intranet site in Ruby on Rails? [closed]

    - by Akromyk
    I'm just coming out of a .Net course and I'm wondering whether it is possible to create an intranet site using Ruby on Rails, and if so, would it even be a good idea. I plan on creating a web site for a vendor that hopes to open up a physical location and it would be beneficial for us to go with a technology that could tie their web front into their intranet for helping them manage orders and logins, but at the same time still have a low cost.

  • Cannot access Compiz Config

    - by Xor power
    I was going through one article here and the topic was "Changing the Size and Appearance of the Unity Launcher" which required to open up CompizConfig from System Settings -- Desktop. I could find System Settings and could reach to control panel but cannot locate either Desktop or CompizConfig. When i go to Software center and search for compizconfig, it says that it is already installed.But when i search it from the list of installed applications, i couldn't find it.??

  • Why shouldn't I be using public variables in my Java class?

    - by Omega
    In school, I've been told many times to stop using public for my variables. I haven't asked why yet. This question: Are Java's public fields just a tragic historical design flaw at this point? seems kinda related to this. However, they don't seem to discuss why is it "wrong", but instead focus on how can they use them instead. Look at this (unfinished) class: public class Reporte { public String rutaOriginal; public String rutaNueva; public int bytesOriginales; public int bytesFinales; public float ganancia; /** * Constructor para objetos de la clase Reporte */ public Reporte() { } } No need to understand Spanish. All this class does is hold some statistics (those public fields) and then do some operations with them (later). I will also need to be modifying those variables often. But well, since I've been told not to use public, this is what I ended up doing: public class Reporte { private String rutaOriginal; private String rutaNueva; private int bytesOriginales; private int bytesFinales; private float ganancia; /** * Constructor para objetos de la clase Reporte */ public Reporte() { } public String getRutaOriginal() { return rutaOriginal; } public String getRutaNueva() { return rutaNueva; } public int getBytesOriginales() { return bytesOriginales; } public int getBytesFinales() { return bytesFinales; } public float getGanancia() { return ganancia; } public void setRutaOriginal(String rutaOriginal) { this.rutaOriginal = rutaOriginal; } public void setRutaNueva(String rutaNueva) { this.rutaNueva = rutaNueva; } public void setBytesOriginales(int bytesOriginales) { this.bytesOriginales = bytesOriginales; } public void setBytesFinales(int bytesFinales) { this.bytesFinales = bytesFinales; } public void setGanancia(float ganancia) { this.ganancia = ganancia; } } Looks kinda pretty. But seems like a waste of time. Google searches about "When to use public in Java" and "Why shouldn't I use public in Java" seem to discuss about a concept of mutability, although I'm not really sure how to interpret such discussions. I do want my class to be mutable - all the time.

  • Problem connecting to certain wifi networks

    - by Romas
    I'm using lenovo u300s (it has Intel Centrino Wireless-N 1030 card), and I can connect to wireless network at home with no problem, but I can not connect to any networks at my university. I'm not sure if it's the case but most of university networks are open and you need to sign up your username as you enter browser. There is also an eudoroam network, but I can not connect to it either. Any suggestions? Yes I have the latest ubuntu version.

  • Running CopySourceAsHtml Add-in under Visual Studio 2010

    - by Marko Apfel
    Until now CopySourceAsHtml only supports Visual  Studio 2008 out of the box. But it is no problem to pimp up the config-file for supporting Visual Studio 2010. Copy all three files to "%userprofile%\Documents\Visual Studio 2010\Addins" Open CopySourceAsHtml.AddIn in a text editor and change both lines with <Version>9.0</Version> to <Version>10.0</Version> Run Visual Studio 2010 and CopySourceAsHtml works fine

  • Running MS Access Programs

    - by fredhappier
    I have an old program developed in MS Access and would like to convert it to Kexi somehow. The program on Windows is launched with Access. Is there any way that Kexi can launch this program? I know my way around Ubuntu and the terminal, but not well versed on databases. Once you make something in Kexi how do you "run" it or "view" what you've made? So far I am able to import the MDB file into Kexi and see all of the database data, but that is as far I have gone. The program was made by a relative years ago for my dad. I myself am an Ubuntu only user for 6+ years now and have no intentions to touch Windows and am looking for a linux solution. My dad is also an Ubuntu user, hence why Im looking for a solution. If Kexi cannot launch and run an MDB file, what else can I try? Anything browser based? Any tips or direction would be extremely helpful. I spoke to my brother who originally made the program. I told him about Kexi and here is what he said. Does any of this make sense? Thanks. This is how I would try to get them to work: Stand alone setup - after import, look for an option where you designate which form object you want to open upon startup. It might be in the tools tab in the picture below. After you save that change, it re-start it and it should work. Front end/back end setup - Do what I suggested for the stand alone setup to the "front-end" MDB file. After you do that, put the other file (table MDB file) where you want it to reside on the network. Now, open back up the "front end" file and look for an option that will allow you to "connect" to those tables in the other file. It looks like it could be in the "External data" tab in the picture below. For this setup, you may need to do these two tasks in the reverse order I just mentioned. Thanks! Fred

  • Cannot access Windows via grub after new dual-boot Ubuntu install

    - by user287474
    I previously installed Ubuntu on a computer that had Windows XP on it and got it successfully to run alongside it. (access both OS systems) Now I installed Ubuntu again on my MSI notebook with Windows 8.1, and I cannot access the GRUB without hitting escape on startup, and even then, I can no longer open windows. Before all of this, I created a recovery point, file history and saved a back up on a external hard drive incase I did anything wrong. Now how can I revert my computer back to it's state before installation.

  • Google Chrome (not chromium) is crashing XFCE on startup. Where can I find some detailed logs of the issue?

    - by MALON
    I'm using xubuntu 12.10 and every time I open Chrome, the desktop enviro crashes then automatically restarts, prompting me to log in again. This is the latest x86 .deb downloaded from Chrome's website. I've tried both installing the .deb using the software package manager and using sudo dpkg -i, same issue for both, except that the package manager puts out an alert that says "This package is of bad quality", but doing a quick google search reveals that particular message is a bug in Chrome and it's safe to ignore.

  • Developing a cloud based app

    - by user134897
    I am a company owner that has developed a cloud based app. My code writer has told me how good he is more than once, well, better stated, he did a good job telling me he was better than everyone else in my rather small community. In the last 18 months I have spent nearly 160,000.00 dollars trying to get this company to the "making money" stage. I am now nearly broke, sitting on the edge of a brilliant marketing plan to launch a much needed cloud based app. We did launch our app last year (late 2013), and the feedback was amazing from the users. One user that signed up to use the free app stated that we needed to call him the moment our company goes public because he wants to be the first to buy stock. Now, here's my problem. We did not originally set out to develop a freemium app, we just sort of ended up there by the natural progression of the app. So, now I have an app that really needs to be scrapped and re-built. Although I do feel my code writer has displayed some brilliance in what he has done, he was extremely weak on graphics and every time we speak he tells me there is a newer better way to code that he is trying to learn. So, here's the million dollar question. Ho do I find code writers that already know the newest, best ways to write code? Or maybe better asked, what is the newest best code writing technique? Second, is it even possible to find code writers that are good at graphics? In short, I am nearly broke and need to start over, but I do not know where to find people qualified to write it good the first time around and display good graphic skills. I am trying to build a team of writers instead of just one person. Maybe 3 good at code and two good at graphics, but I am clueless as to what criteria I should use to determine if I am building the right team members. Please help, I am sure you can tell I am fairly lost by my continued rambling.
