• Xorg becomes unkillable at 3AM

  - by chew socks

  Most nights, some time in the hour of 3AM my xorg process will increase to 100% cpu and gpu load will also increase to 100%. The process also becomes unkillable. I cannot sudo kill -9 it or get back control with sudo service lightdm restart. I also cannot switch to to a tty screen with ctrl + alt + f1. To reboot I have to log in with ssh, but this is not perfect because if I reboot while it is doing this my ZFS pool will fail to mount when it comes back up ( that is where my /home is ). Does anyone have any ideas as to why I can't stop and restart xorg, or even better, know why this is happening? Thanks NOTE: For anyone who comes looking for the same problem. I disabled catalyst AI and made it through the night. I've been up for 1 day 3 hours now. My record for this month is 2 days and 19 hours without a problem. My all time record is 6 days without a crash. I'll post here if it crashes again or I'm able to set a new record.

• So, I though I wanted to learn frontend/web development and break out of my comfort zone...

  - by ripper234

  I've been a backend developer for a long time, and I really swim in that field. C++/C#/Java, databases, NoSql, caching - I feel very much at ease around these platforms/concepts. In the past few years, I started to taste end-to-end web programming, and recently I decided to take a job offer in a front end team developing a large, complex product. I wanted to break out of my comfort zone and become more of an "all around developer". Problem is, I'm getting more and more convinced I don't like it. Things I like about backend programming, and missing in frontend stuff: More interesting problems - When I compare designing a server that handle massive data, to adding another form to a page or changing the validation logic, I find the former a lot more interesting. Refactoring refactoring refactoring - I am addicted to Visual Studio with Resharper, or IntelliJ. I feel very comfortable writing code as it goes without investing too much thought, because I know that with a few clicks I can refactor it into beautiful code. To my knowledge, this doesn't exist at all in javascript. Intellisense and navigation - I hate looking at a bunch of JS code without instantly being able to know what it does. In VS/IntelliJ I can summon the documentation, navigate to the code, climb up inheritance hiererchies ... life is sweet. Auto-completion - Just hit Ctrl-Space on an object to see what you can do with it. Easier to test - With almost any backend feature, I can use TDD to capture the requirements, see a bunch of failing tests, then implement, knowing that if the tests pass I did my job well. With frontend, while tests can help a bit, I find that most of the testing is still manual - fire up that browser and verify the site didn't break. I miss that feeling of "A green CI means everything is well with the world." Now, I've only seriously practiced frontend development for about two months now, so this might seem premature ... but I'm getting a nagging feeling that I should abandon this quest and return to my comfort zone, because, well, it's so comfy and fun. Another point worth mentioning in this context is that while I am learning some frontend tools, a lot of what I'm learning is our company's specific infrastructure, which I'm not sure will be very useful later on in my career. Any suggestions or tips? Do you think I should give frontend programming "a proper chance" of at least six to twelve months before calling it quits? Could all my pains be growing pains, and will they magically disappear as I get more experienced? Or is gaining this perspective is valuable enough, even if plan to do more "backend stuff" later on, that it's worth grinding my teeth and continuing with my learning?

• Sample domain model for online store

  - by Carel

  We are a group of 4 software development students currently studying at the Cape Peninsula University of Technology. Currently, we are tasked with developing a web application that functions as a online store. We decided to do the back-end in Java while making use of Google Guice for persistence(which is mostly irrelevant for my question). The general idea so far to use PHP to create the website. We decided that we would like to try, after handing in the project, and register a business to actually implement the website. The problem we have been experiencing is with the domain model. These are mostly small issues, however they are starting to impact the schedule of our project. Since we are all young IT students, we have virtually no experience in the business world. As such, we spend quite a significant amount of time planning the domain model in the first place. Now, some of the issues we're picking up is say the reference between the Customer entity and the order entity. Currently, we don't have the customer id in the order entity and we have a list of order entities in the customer entity. Lately, I have wondered if the persistence mechanism will put the client id physically in the order table, even if it's not in the entity? So, I started wondering, if you load a customer object, it will search the entire order table for orders with the customer's id. Now, say you have 10 000 customers and 500 000 orders, won't this take an extremely long time? There are also some business processes that I'm not completely clear on. Finally, my question is: does anyone know of a sample domain model out there that is similar to what we're trying to achieve that will be safe to look at as a reference? I don't want to be accused of stealing anybody's intellectual property, especially since we might implement this as a business.

• startx error no desktop manager

  - by WikiWitz

  I have Backtrack 5R2 KDE. I started recovery mode and did a failsafe xorg configuration. After that, I cannot load the KDE manager when I enter the startx command after logging in. Whenever I do a startx command (as root), the result resembles the following: This is not the actual output (I just drew this with MS paint because I cannot do a printscreen). The screen is just black with the icon in the upper left corner. The other pop-up menu appears when left-clicking the mouse. I tried the cp xorg.conf.failsafe xorg.conf advice from other websites with no luck. I have also tried the 'reconfigure option(s)' form the recovery mode with no success.

• A fix for the design time error in MVVM Light V4.1

  - by Laurent Bugnion

  For those of you who installed V4.1 of MVVM Light and created a project for Windows Phone 8, you will have noticed an error showing up in the design surface (either in Visual Studio designer, or in Expression Blend). The error says: “Could not load type ‘System.ComponentModel.INotifyPropertyChanging’ from assembly ‘mscorlib.extensions’” with additional information about version numbers. The error is caused by an incompatibility between versions of System.Windows.Interactivity. Because this assembly is strongly named, any version incompatibility is causing the kind of error shown here (for an interesting discussion on the strong naming issue, see this thread on Codeplex). I managed to resolve the issue for Windows Phone 8 and will publish a cleaned up installer next week. In the mean time, in order to allow you to continue development, please follow the steps: Download the new DLLs zip package (MVVMLight_V4_1_25_WP8). Right click on the Zip file and select Properties from the context menu. Press the “Unblock” button (if available) and then OK. Right click again on the zip package and select “Extract all…”. Select a known location for the new DLLs. Open the MVVM Light project with the design time error in Visual Studio 2012. Open the References folder in the Solution Explorer. Select the following DLLs: GalaSoft.MvvmLight.dll, GalaSoft.MvvmLight.Extras.dll, Microsoft.Practices.ServiceLocation.dll and System.Windows.Interactivity.dll. Press “delete” and confirm to remove the DLLs from your project. Right click on References and select Add Reference from the context menu. Browse to the folder with the new DLLs. Select the four new DLLs and press OK. Rebuild your application, and open it again in Blend or in the Visual Studio designer. The error should be gone now. In the next few days, as time allows, I will publish a new MSI containing a fixed version of the DLLs as well as a few other improvements. This quick fix should however allow you to continue working on your Windows Phone 8 projects in design mode too.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• how to figure out why sites on my server aren't loading

  - by Derek

  I seem to randomly receive "page cannot load, cannot connect to server" errors for sites on one of my servers. when this happens, it seems to only happen on certain IPs or IP ranges at a time. I say this because while I'll get the error from my home laptop I'll be able to access the site fine from my work computer or from an offsite VPS. DNS records should already be fully propagated as these records were updated months ago. I have no idea how to diagnose what's going on. Is there a tool in cpanel or outside on the web that can help me figure out what's going on?

• timeout with apache & php w/ each virtual host has his own user process

  - by acemtp

  I have 10 unix users in /home/. Each user is for a specific subdomain for example user www in /home/www/public_html is for www.mywebsite. blog in /home/blog/public_html is for blog.mywebsite. 90% is php and 10% ror for the moment i use apache + fastcgi that use SuexecUserGroup to setup the process with the good user. it seems to works but i have a strange behavior where after a few hours/days, the server stop answering (timeout) but the cpu load is still very low (it's a big server), the apache status display lot of "W" Sending Reply states but there's still 50 idle workers so it should be able to answer. in the older server (lot of slower) we add only one user and using mod_php and we never had this issue. is there another way to do that without fastcgi and SuexecUserGroup or do you know what's going wrong?

• Servers at remote sites vs. centralized servers?

  - by Boden

  Looking for some opinions here. We've got three physical locations and site-to-site VPN between all three. Currently we've got Windows domain controllers at each location, with roughly 50 clients at each. The domains are currently separate, and we're looking at integrating the three sites. Email (Exchange) will be located at the primary site, and RPD is already being used at the secondary branches to hit the app servers also located at the primary site. The bulk of the local user load at the other two sites is just file sharing. What would the main benefits and drawbacks be of replacing the local domain controllers with NAS devices, and only keeping the domain controller(s) at the primary site? (assuming upgrades are coming regardless) Under what circumstances would you choose one setup over the other?

• Routing application traffic through specific interface

  - by UnicornsAndRainbows

  Hello All! First question here, so please go easy: I have a debian linux 5.0 server with two public interfaces. I would like to route outbound traffic from one instance of an application via one interface and the second instance through the second interface. There are some challenges: both instances of the application use the same protocol both instances of the application can access the entire internet (can't route based on dest network) I can't change the code of the application I don't think a typical approach to load balancing all traffic is going to work well, because there are relatively few destination servers being accessed in the outbound traffic, and all traffic would really need to be distributed pretty evenly across these relatively few servers. I could probably run two virtualized servers on the box and bind each of them to a different external ip, but I'm looking for a simpler solution, maybe using iproute or iptables? Any ideas for me? Thanks in advance - and I'm happy to answer any questions.

• Why do some web servers not respond to icmp requests?

  - by John Himmelman

  What is the purpose of blocking/dropping inbound ICMP traffic on a public web server? Is it common for it be blocked? I had to test if a server was accessible from various locations (tested on various servers located in different states/countries). I'd rely on ping as a quick & reliable method of determining if a server was online/network-accessible. After not receiving a response on a couple boxes, I tried using lynx to load the site, and it worked.

• Port Redirection on Mac OS X Lion

  - by Andreas

  I have tried to solve this issue using pf but with no luck. Basically, I am trying to redirect incoming port 443 traffic to port 22. I have tried to set up a rule in a file and load it in pf but I get syntax error. Can anyone with more experience with pf provide some insight? Here's what I've attempted: pass in on en1 proto tcp from any to any port 443 rdr-to 127.0.0.1 port 22 and pass in quick proto tcp to port 443 rdr-to 127.0.0.1 port 22 I've been able to do this in MacOSX Snow Leopard with ipfw: sudo ipfw add 1443 forward 127.0.0.1,22 ip from any to any 443 in but it doesn't work in Lion (it gives me an Invalid Argument error).

• Android - Efficient way to draw tiles in OpenGL ES

  - by Maecky

  Hi, I am trying to write efficient code to render a tile based map in android. I load for each tile the corresponding bitmap (just one time) and then create the according tiles. I have designed a class to do this: public class VertexQuad { private float[] mCoordArr; private float[] mColArr; private float[] mTexCoordArr; private int mTextureName; private static short mCounter = 0; private short mIndex; As you can see, each tile has it's x,y location, a color array, texture coordinates and a texture name. Now, I want to render all my created tiles. To reduce the openGL api calls (I read somewhere that the state changes are costly and therefore I want to keep them to a minimum), I first want to hand ALL the coordinate-arrays, color-arrays and texture-coordinates over to OpenGL. After that I run two for loops. The first one iterates over the textures and binds the texture. The second for loop iterates over all Tiles and puts all tiles with the corresponding texture into an IndexBuffer. After the second for loop has finished, I call gl.gl_drawElements() whith the corresponding index buffer, to draw all tiles with the texture associated. For the next texture I do the same again. Now I run into some problems: Allocating and filling the FloatBuffers at the start of each rendering cycle costs very much time. I just run a test, where i wanted to put 400 coordinates into a FloatBuffer which took me about 200ms. My questions now are: Is there a better way, handling the coordinate and color structures? How is this correctly done, this is obviously not the optimal way? ;) thanks in advance, regards Markus

• How do you debug why Windows is slow?

  - by aaron

  I've got Vista Biz and when my machine chugs I think it is because of paging, but I never know how to verify this. Procexp doesn't seem to provide useful information because it appears that nothing is going on when the chugs happen. perfmon seems like it has the counters I need, but I'm never sure what counters I should add to cover the information I want. For perfmon, I prefer numbers that are percents, so I can gauge load. Here are the counters I have up, but they don't always seem to correlate to chugs: - % disk time (logical) - page faults/sec (an indicator of lots of paging activity) - processor/%priviliged time

• Reserve one http slot for /server-status?

  - by Stefan Lasiewski

  I have an Apache server which is hanging for some reason. When I normally want to check on the load of an Apache server, I tend to use mod_status via the URL at http://webserver1.example.org/server-status or from the commandline like service httpd fullstatus. However today, the Server is refusing all new connections. Some mysterious problem is causing connections to stall, which means that number of connections fills up all available connections (e.g. The number of connects exceeds the MaxClients setting), and therefore neither http://webserver1.example.org/server-status nor service httpd fullstatus can return anything. Is it possible to configure Apache to reserve one or two slots for the mod_status pages?

• Embedded Tomcat Cluster

  - by ThreaT

  Can someone please explain with an example how an Embedded Tomcat Cluster works. Would a load balancer be necessary? Since we're using embedded tomcat, how would two separate jar files (each a standalone web application with their own embedded tomcat instance) know where eachother are and let eachother know their status, etc? Here is the code I have so far which is just a regular embedded tomcat without any clustering: import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.File; import java.io.IOException; import java.io.Writer; public class Main { public static void main(String[] args) throws LifecycleException, InterruptedException, ServletException { Tomcat tomcat = new Tomcat(); tomcat.setPort(8080); Context ctx = tomcat.addContext("/", new File(".").getAbsolutePath()); Tomcat.addServlet(ctx, "hello", new HttpServlet() { protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { Writer w = resp.getWriter(); w.write("Hello, World!"); w.flush(); } }); ctx.addServletMapping("/*", "hello"); tomcat.start(); tomcat.getServer().await(); } } Source: java dzone

• How do I setup a local DNS server on Mac OS Lion?

  - by Peter Kovacs

  I had some serious lag to resolve website address and sometimes things simply wouldn't load (pages kept loading for 5+ minutes without even a timeout error). So I had setup a local dns server/cache using BIND on Leopard and Snow Leopard. Now that I have Lion, i have the same problem, but the instructions no longer apply to Lion and I can't find a way to do it. Has anyone attempted to do this? Are there viable alternatives for DNS servers on OS X 10.7? For those who are wondering I already tried several external DNS server. Only my computer has this issue on the network.

• ASP.NET MVVM Handling multiple Data Transfer Objects on a single page

  - by meffect

  I have an asp.net mvc "edit" page which allows the user to make edits to the parent entity, and then also "create" child entities on the same page. Note: I'm making these data transfer objects up. public class CustomerViewModel { public int Id { get; set; } public Byte[] Timestamp { get; set; } public string CustomerName { get; set; } public etc.. public CustomerOrderCreateViewModel CustomerOrderCreateViewModel { get; set; } } In my view I have two html form's. One for Customer "edit" Http Posts, and the other for CustomerOrder "create" Http Posts. In the view page, I load the CustomerOrder "create" form in using: <div id="CustomerOrderCreate"> @Html.Partial("Vendor/_CustomerOrderCreatePartial", Model.CustomerOrderCreateViewModel) </div> The CustomerOrder html form action posts to a different controller HttpPost ActionResult than the Customer "edit" Action Result. My concern is this, on the CustomerOrder controller, in the HttpPost ActionResult [HttpPost] public ActionResult Create(CustomerOrderCreateViewModel vm) { if (!ModelState.IsValid) { return [What Do I Return Here] } ...[Persist to database code]... } I don't know what to return if the model state isn't valid. Right now it's not a problem, because jquery unobtrusive validation handles validation on the client. But what if I need more complex validation (ie: the server needs to handle the validation).

• how long does noip ddns takes to make the updated address again accessible?

  - by neoDev

  Yesterday I've created a noip account, I've downloaded the updater client (DUC), I've configured them, and when I've tryied to browse "myaddress.noip.me" all worked fine... When my WAN IP changes, the DUC client quickly updates it in few minutes, and in my account on noip.com I can see that it is also refreshed properly. But the problem is that if I try to browse "myaddress.noip.me" after that update, the page does not load... "Unable to connect to myaddress.noip.me" After 6-7 hours it becomes again accessible, but I'm not sure if this is normal... I think this is too much time... Please help

• IIS not listening over external network, all other traffic working

  - by Beuy

  Hello there, I have a very odd situation, I have a server (let's call it X) running 2008 R2 with two NIC's in it, one is connected to the work domain and has a subnet of 192.168.10.0/24 the other is connected to a ADSL connection and has a subnet of 192.168.1.0/24. The server has IIS installed. On the ADSL connection I have setup a dynamic dns and port forwarding to allow external HTTP, HTTPS, FTP and RDP connections. FTP and RDP are working fine however neither HTTP or HTTPS are working at all. I can browse the websites by going to localhost on the machine, the HTTP and HTTPS ports appear as "Filtered" when I try to scan them using PortQueryUI and browsers respond with a "Server took too long to load or was not responding" error.
