• Internet setup for my office

  - by prakash

  We have two internet connections to our office and our current setup is like this.. The internet connections require pppoe log in so i take each cable and plug it into a wifi router and configure the router to log in to the pppoe and then plug in a cable from the router to a switch and distribute the internet throughout my office. The problem with this setup is it is really hard to monitor and im not able to monitor who is hogging internet usage and what he or she is actually using it for. apart from this we also have a nas setup which is routed through another switch . Could someone please throw a little light on how i can restructure this setup for easy monitoring and better transparency... ? each wan router is connected to a different switch and is distributed to users accordingly.. we have around 40 users in the office.. we want to setup a single linux box to which i want to connect the two wan connections and from there distribute it to all our users.... im looking for a solution where we do not have to invest more that buying a single pc and a couple of nics

• Best choice for 3D Physics Engine for C#/XNA

  - by Nic Foster

  Since 2007 I've been working on the development of an open-source game engine, and have been using JigLibX for 3D Physics. However, the developers on the project have stopped contributing to it for over 2 years now, and it's lacking features I need, or have major bugs in certain features. What are some good choices for 3D physics engines that are written purely in C#? Are there any that are more complete than JigLibX? EDIT: I just stumbled upon an engine called BEPUphysics. It was supported up until May 2012, which is fairly recent. I may check it out, any information that you guys could give on how complete the engine is would be great.

• PostgreSQL, Ubuntu, NetBeans IDE (Part 2)

  - by Geertjan

  Now let's create the start of a CRUD application on the NetBeans Platform, using Hibernate and PostgreSQL to do so. Here's what I see in NetBeans IDE after setting things up as outlined yesterday: The NetBeans Platform CRUD Tutorial should get you up and started creating the NetBeans Platform application. Open the generated "persistence.xml" in Design mode and then switch the persistence library to Hibernate. The Here's the application structure: The Hibernate module that you see above has this content: Here's the result: And here's the source code: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/misc/NBPostgreSQL

• How can I make a case for "dependency management"?

  - by C. Ross

  I'm currently trying to make a case for adopting dependency management for builds (ala Maven, Ivy, NuGet) and creating an internal repository for shared modules, of which we have over a dozen enterprise wide. What are the primary selling points of this build technique? The ones I have so far: Eases the process of distributing and importing shared modules, especially version upgrades. Requires the dependencies of shared modules to be precisely documented. Removes shared modules from source control, speeding and simplifying checkouts/check ins (when you have applications with 20+ libraries this is a real factor). Allows more control or awareness of what third party libs are used in your organization. Are there any selling points that I'm missing? Are there any studies or articles giving improvement metrics?

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• How to avoid whitespace in PHP and ASP.NET? [closed]

  - by Goma

  You know that the PHP interpreter avoids whitespace and comments. However, I have heared that there is something you can do to make the interpreter does not see the whitespace at all and does not even think to avoid it, the same for the compiler in ASP.NET. What is that thing? Is it a function in PHP and a class in ASP.NET? or what exactly? Edit: For example the php_strip_whitespace function in PHP "Returns the PHP source code in filename with PHP comments and whitespace removed". Will this help in load time?

• Let apache run perlscripts that don't have an extension

  - by tiMbeRdroP

  I'd like to use perlscripts without their extension. f.e. "index" instead of "index.pl". Changing the DefaultType-directive from text/plain to application/x-perl didn't do the trick. Instead of running the script the server offered to download its source. I'm not exactly sure if changing this directive is the right approach. Telling apache to read the shebang-line when there is no extension sounds much better to me. I hope someone with more experience on this topic can help me out.

• Where to put git "remote" repo on purely local git setup?

  - by Mittenchops

  I overwrote and lost some important scripts and would like to setup version control to protect my stuff. I've used git before, and am familiar with commands, but don't understand where I would put my "remote" repository on an install set up on my own machine---the place I push/pull to. I don't intend to share or access remotely, I just want a little source control for my files. I followed the instructions here for setting up my staging area: http://stackoverflow.com/questions/4249974/personal-git-repository But where do I put git "remote" repo on purely local git setup? How does the workflow work then? On the command in the above: git remote add origin ssh://myserver.com:/var/repos/my_repo.git Where should I put/name something like this? If I have multiple different projects, would they go in different places? I'm running 11.10.

• Oneiric is freezing. Need help diagnosing and filing a bug

  - by mlissner

  Six months ago, I bought a new Sandy Bridge CPU and built myself a nice desktop machine. Until now it hasn't worked...at all. I finally have gotten it working now that Oneiric is released, but it freezes every so often, making it little more than a semi-functional temptation. What happens when the system freezes is: the music I have playing enters into about 5s loops. SSH fails the monitor freezes the mouse freezes the keyboard fails The only way to fix it is to do a hard reset...and that sucks. I'd love to at least figure out the source of the freeze so I can file a bug. I've looked in dmesg, kern.log, and the X.org logs. Nothing interesting is any of them. Since SSH fails, I'm convinced it's not an X crash: https://wiki.ubuntu.com/X/Troubleshooting/Freeze Anything else I can do?

• I enabled and setup glBlendFunc, but my texture has a white outline. What am I doing wrong?

  - by vinzBad

  You can see most of my source code in this question: Instead of the specified Texture, black circles on a green background are getting rendered. Why? Now I have the problem, that my texture has a white outline on its transparent parts. After googling and setting up glBlendFunc, the outline just got "softer". This is how it looks like: This is how I now setup OpenGL: public static void SetupGL() { GL.Enable(EnableCap.Blend); GL.BlendFunc(BlendingFactorSrc.SrcAlpha, BlendingFactorDest.OneMinusSrcAlpha); GL.Enable(EnableCap.Texture2D); GL.Hint(HintTarget.PerspectiveCorrectionHint, HintMode.Nicest); }

• How to handle "porting" software that's still in development

  - by BAM

  My company is building an iOS version of an Android app that our client is developing (but has not yet released). We have access to the latest builds and source, however since the software is frequently re-structured and refactored, we're doing a lot of unnecessary re-work. In addition, the due date on the contract will likely be passed before the client's application is even ready for release. In other words, we're supposed to build the iOS version before the original Android version is even complete. Luckily the client tossed out the original deadline, but now we may have to renegotiate pricing... never a fun situation. Are we handling this incorrectly? How are "ports" (especially between mobile platforms) normally done? Is there a correct way to pipeline development for multiple platforms without so much re-work? Thanks in advance! :)

• Eclipse Indigo freezes on 'Open Type' search

  - by NickGreen

  When I'm trying to search for a Java class with Ctrl-shift-T (Open Type popup), Eclipse freezes when I'm typing 1 character. It usually takes about 8 seconds to 'unfreeze', but sometimes it won't come back at all.. When it freezes, I see that the eclipse process takes about 1Gig of mem and the CPU is about 100%! I've tried creating a new workspace, adjusting the eclipse.ini (perm size, different memory values), starting with -clean and at last reinstall the whole IDE. Nothing helps.. My eclipse.ini: -startup plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar --launcher.library plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505 -product org.eclipse.epp.package.jee.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 768m --launcher.defaultAction openFile -vmargs -server -Dosgi.requiredJavaVersion=1.5 -Xmn128m -Xms1024m -Xmx1024m -Xss2m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseParallelGC -Djava.library.path=/usr/lib/jni I'm using the following plugins: JRebel and m2e. I'm desperate for a solution because this problems causes me a great deal of time loss. System: Ubuntu 12.04 LTS 64 bit, 4GB mem, Intel core i7 860 @ 2.8 Ghz. Hope somebody knows a solution. Thank you for your time.

• Is it better to always copy and delete, rather than move?

  - by nbolton

  Generally speaking, I find myself panicking when I realise that if I cancel a file move, it could cause the target or source to be incomplete. This question applies to Windows and Unix-based platforms. I can never remember exactly how the move command works in either case. For example, if you're moving a directory; does it copy the entire directory, then delete it after, or does it copy then delete each file individually? I always realise after typing something like, mv verybigdir dest that I really should have typed cp -R verybigdir dest && rm verybigdir (where the && operator only moves to the next command if the first was successful) -- or is this pointless? What happens exactly when I press Ctrl+C half way through a move? Likewise, what exactly happens on Windows when I press the cancel button? I can't count the number of times I've moved something (the last time was when using svn) and had two directories, with split contents. I guess the answer is difficult, because not all applications move groups of files in the same way.

• Cannot save all of the property settings for this Web Part.

  - by ybbest

  I would like to display all the items of custom content type of Animals in a SharePoint content query WebPart. After choosing the appropriate values in the web part editor and click on Save I got this error: Cannot save all of the property settings for this Web Part. There is a problem with one or more of the field values below. But when I examine all the values below , it does not flag any error information. I finally manage to locate the error flag after I expand the presentation section. I then delete the text in the Link textbox , now I can save the settings. However , I think the error message should have been more specific so that users can quickly locate the error. The worst part for this is that I did not even change anything in the presentation section, I merely configure the Source in the Query section. Well, I guess I am still new to SharePoint, I just have to get used to these generic error message ):

• Best practice for comments above methods in a grails application?

  - by Travis

  I'm writing a grails application and am not sure what the best practice is with regard to comments outside of method blocks. I've done a bit of research and there seems to be conflicting views on how and when these sort of comments should be used. In lots of source code I have seen there seems to be comments above every method detailing what that method does. I'm not sure if grails should be differnet? My question is should I have a comment above each method in my controllers, services and domain objects? i.e /* * This method displays the index page */ def index(){ render view : "index" }

• Installing Visual Studio Express on Windows 8.1

  - by robrene

  I've been trying to install the latest version of Microsoft Visual Studio Express from their website to toy around with the IDE and C# development in general. I have a relatively fresh and completely vanilla installation of Windows 8.1 Professional x64 for this purpose. I come from a Linux background, where installing software (especially software distributed by the maintainer of the OS) is usually done with package managers. First, I tried to look for Visual Studio in the Windows 8 Store. There was one entry, but it did not have an installation button. Instead, it redirected me to their website. From all the products listed under the "Download" section on their website, I decided Visual Studio 2013 Express for Windows Desktop was the best for me. I selected it and clicked on "Install now". An installer program downloaded, and I'm assuming that the installer downloaded the necessary files as it was running. When it was done, it asked for a reboot, to which I obliged. However, I can't seem to find the IDE installed anywhere? It doesn't show up anywhere in the Start menu interface. I can't find any executables that look like they might be the IDE in its installation folder. Running the installer again and selecting "Repair" does download some files, but after its requested reboot, nothing has changed. The only thing that I can find is an advertisement link to "Try other Visual Studio 2013 Products" in my start menu. I suppose my question is what I have to do to run Visual Studio 2013 Express on Windows 8.1? Am I not looking in the right places? Am I doing the installation process wrong? Thanks in advance

• Algorithm development in jobs

  - by dbeacham

  I have a mathematics background but also consider career in some form of software development. In particular I'm interested in finding out what sort of industries are most likely to have more algorithm development/mathematical and logical problem solving slant rather than pure application development etc. Obviously, I'm assuming that some subset of the canonical data structures and associated algorithms (trees, lists, hash tables, sets, maps with search, insert, traversals etc.) are mostly going to be present in software development. However, where am I more likely to encounter problems of more discrete maths nature (combinatorial, graph theory, sets, strings, ...) explicitly or more likely in disguise. Any pointers much appreciated (including possible open source projects that I could use for my further search for applications and also possibly contribute to).

• Managed LAMP platform for maximizing availability and global reach, not scalability

  - by user66819

  Assume a Linux/Apache/MySQL/PHP application for a small base of registered users. With small userbase, there are no traffic peaks so the scalability that cloud platforms offer is not imperative. But the system is mission-critical, so availability is the primary goal. Users are also distributed across Asia, Europe, and US, so multiple server locations that minimize users' network hops would be highly desirable. The dream: a managed VPS platform where we would configure a single server (uploading PHP and other files, manipulating database, etc.), and the platform would automatically mirror the server in a handful of key places around the world (say one on each US coast, one in Europe, one in east Asia). File system synchronization and MySQL replication would happen automatically. Core operating system is managed, so we don't need to do full system administration and security, and low-level backups are also done by service provider, though we also do our own backups as well. Couple this with some sort of DNS geo-detection, so users are routed to the nearest operational server... with support for https, of course. Does such a dream exist? If not, what are some approaches to accomplish the same end with minimal time investment and minimal monthly hosting costs?

• Repeater vs. ListView

  - by MoezMousavi

  I do really hate repeater. I was more a GridView lover but after 3.5 be born, I prefer ListView.  The first problem with Repeater is paging. You will need to write code to handle paging. Second common problem is empty data template. Have a look at this:             if (rptMyRepeater.Items.Count < 1)             {                 if (e.Item.ItemType == ListItemType.Footer)                 {                     Label lblFooter = (Label)e.Item.FindControl("lblEmpty");                     lblFooter.Visible = true;                 }             }   I found the above code is usefull if you need to show something like "There is no record" is your data source has no records. Although the ListView has a template.   If you combine ListView with a DataPager, you will be in heaven as it is sorting the paging for you without writing code. (http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.datapager.aspx)     Note: You have got to bind ListView in PreRender, it doesn't work properly in PageLoad   More: http://www.4guysfromrolla.com/articles/061009-1.aspx

• Emacs24: emacsclient doesn't use global application menu

  - by codethief

  I noticed that Emacs24 makes use of Unity's global application menu. (I'm using Damien Cassou's Emacs24 snapshots.) However, it doesn't do that when emacs, emacsclient or emacsclient.emacs24 are run but just with emacs24. How can I fix that? (Is that a bug? If so, should I file a report in Emacs' or libappmenu's bugtracker?) [EDIT]: As far as I can see this could be related to https://bugs.launchpad.net/ubuntu/+source/appmenu-gtk/+bug/673302 .
