  • Return http status ok (200) on request method OPTIONS Apache

    - by jazz
    I have a apache server which uses Reverse Proxy to connect/direct to a tomcat server. Using virtualHost, RequestHeader set X-Forwarded-Proto "http" ServerName image.abc.local DocumentRoot "/var/www/html" ProxyRequests Off ProxyTimeout 600 ProxyPass /abc http://image.abc.local:9001/abc ProxyPass /xyz http://image.abc.local:9001/xyz ProxyPassReverse /abc http://image.abc.local:9001/abc ProxyPassReverse /xyz http://image.abc.local:9001/xyz what i want to achieve here is that, when there is a REQUEST_METHOD OPTIONS i want simply return HTTP status OK (200). I dont want the request to be received by the tomcat server and process it. For performance based concerns i want this request to be handled at apache level. with all the research i was still unable to get this to run; RewriteEngine on RewriteCond %{REQUEST_METHOD} OPTIONS RewriteRule .* - [R=200m] can somebody assist me with what rewrite rule should be there? or is there an alternative to RewriteEngine? Thanks

  • Should interfaces inherit interfaces

    - by dreza
    Although this is a general question it is also specific to a problem I am currently experiencing. I currently have an interface specified in my solution called public interface IContextProvider { IDataContext { get; set; } IAreaContext { get; set; } } This interface is often used throughout the program and hence I have easy access to the objects I need. However at a fairly low level of a part of my program I need access to another class that will use IAreaContext and perform some operations off it. So I have created another factory interface to do this creation called: public interface IEventContextFactory { IEventContext CreateEventContext(int eventId); } I have a class that implements the IContextProvider and is injected using NinJect. The problem I have is that the area where I need to use this IEventContextFactory has access to the IContextProvider only and itself uses another class which will need this new interface. I don't want to have to instantiate this implementation of IEventContextFactory at the low level and would rather work with the IEventContextFactory interface throughout. However I also don't want to have to inject another parameter through the constructors just to have it passed through to the class that needs it i.e. // example of problem public class MyClass { public MyClass(IContextProvider context, IEventContextFactory event) { _context = context; _event = event; } public void DoSomething() { // the only place _event is used in the class is to pass it through var myClass = new MyChildClass(_event); myClass.PerformCalculation(); } } So my main question is, would this be acceptable or is it even common or good practice to do something like this (interface inherit another an interface): public interface IContextProvider : IEventContextFactory or should I consider better alternatives to achieving what I need. If I have not provided enough information to give suggestions let me know and I can provide more.

  • Drupal CMS most Stable for High Traffic

    - by Aditi
    Drupal users have high satisfaction with Drupal compared to the Joomla users, for a number of reasons. If you are thinking of  choosing a high performance platform to run your high traffic website.. Drupal Installation is your forte! Overload Scenario Drupal is scalable high performance CMS and is stable under heavy load. If your server is pushed beyond its capacity, Drupal shuts off gracefully and doesn’t crash. As soon as the server is back within its traffic capability, Drupal handles all requests smoothly again. For example if your dedicated server can handle a maximum of 50,000 visits a day, and on lucky days when your news created the buzz in social media and your traffic rose to 70,000 on one day, then your server will be overloaded and usually it crashes causing permanent damage to your database at times.. But if you have used Drupal CMS it closes down gracefully an as soon as traffic goes down to within the server’s capacity, the Drupal running site accepts all requests again. Extensibility Drupal users know that their add-ons integrate better with the core, and their framework makes it easier to extend their CMS’s capabilities.. which makes an extended version of it quite stable unlike Joomla, which loses its strength if you have plenty of plugins & heavy customizations running. Any CMS with number of plugins makes the content complex and reduces your ability to handle high traffic requests. Accessibility Management or ACL Chances are if you are high traffic website, you may have various users & content contributors. ACL means group roles that is assigning people out of the various registered user levels and allocating many kinds of privileges. The most common example is the ability to see or edit a section or selected pages. This efficient feature of Drupal makes it a class apart than other CMSs out there.

  • Idea for a physics–computer science joint curriculum and textbook

    - by Ami
    (I apologize in advance if this question is off topic or too vague) I want to write (and have starting outlining) a physics textbook which assumes its reader is a competent computer programmer. Normal physics textbooks teach physical formulas and give problems that are solved with pen, paper and calculator. I want to provide a book that emphasizes computational physics, how computers can model physical systems and gives problems of the kind: write a program that can solve a set of physics problems based on user input. Third party open source libraries would be used to handle most of the computation and I want to use a high-level language like Java or C#. Besides the fact I'd enjoy working on this, I think a physics-computer science joint curriculum should be offered in schools and this is part of a large agenda to make this happen. I think physics students (like myself) should be learning how to use and leverage computers to solve abstract problems and sets of problems. I think programming languages should be thought of as a useful medium for engaging in many areas of inquiry. Is this an idea worth pursuing? Is the merger of these two subjects in the form of an undergraduate college curriculum feasible? Are there any specific tools I should be leveraging or pitfalls I should be aware of? Has anyone heard of college courses or otherwise that assume this methodology? Are there any books/textbooks out there like the one I'm describing (for physics or any other subject)?

  • How to Find Your IP Address in Ubuntu Linux

    - by Trevor Bekolay
    In Windows, we use the command-line program ipconfig to find out our IP address. How do you find it in Ubuntu? We will show you two locations easily accessible through the GUI and, of course, a terminal command that will get your IP address in no time. The first location, and the easiest in most cases, is found by right clicking the network icon in the notification area and clicking Connection Information. This brings up a window which has a bunch of information, including your IP address. The second location, which shows you more detail than this first method, is at System > Administration > Network Tools. Select the right network device, and you’ve got a ton of information at your fingertips. Finally, if you can’t tear yourself away from a terminal window, the command to type in is: ifconfig Yes, it’s only one character different than ipconfig. Who would have guessed? As it turns out, you’re always a few clicks or keystrokes away from finding your IP address in Ubuntu. Isn’t choice great?

  • Dolby Digital Live (DDL) on Asus Rampage II Gene (Creative X-Fi Extreme)

    - by kevyn
    Hi there, I have an Asus Rampage II Gene motherboard which has X-Fi extreme built in. I can get it to work with Windows 7 ok using the Creative drivers, however when I try and install the DDL/DTS add on pack from Creative I get the error message: "There are no supported audio device available. You need to close the application. Click OK to close the application now" I don't understand it because I have the Creative software installed ok and supporting the sound without any problems. In Device manager the audio device comes up as 'High definition audio device' and uses driver: 6.1.7600.16385 from Microsoft. I tried using the Creative drivers which show up as 'soundmax HD audio' however these do not allow any of the Creative products to run properly. Please can anyone offer any help? Or even just confirm that DDL can work with my onboard sound? Windows 7 Ultimate 64 bit 6GB DDR3 XFX GS8800 384mb Asus Rampage II Gene Intel i7 920 (2.66)

  • guvciew/youtube problem

    - by Anonymous
    I'm fairly new to Linux. Running on 12.10 Ubuntu. I've been running into some problems recording videos. Cheese crashes (as I've read from other users), YouTube will not allow me to select Allow (flash in Chrome and in Firefox). I managed to get 1 video uploaded from my cam and it worked about half the time, cut the audio off, lagged, etc. My computer is fine 4gigs, 32-bit i5 so it shouldn't be a problem. Now onto guv, I managed to get 1 video to work and after that every video I save it comes up with an orange file that looks like a film. I tried to change the file name, open in VLC, everything. I love Ubuntu and I'm never going back to Windows, ever One other thing to note is I am allowed to click "allowed" in Tiny chat. I even went to the adobe website to allow everything to bypass allow, deny option and nothing. Even went out of my way to add youtube/upload/cam for it to allow it and nothing. I realize right now Flash has been terrible for the past couple of months (especially in Chrome). What my question is well first and foremost, how do I fix this, if possible? I've thought about running Wine but I haven't heard anything good about it and I've already re reformated Ubuntu twice. Is there a codec pack I need too? Like I said everything works fine, especially in Chrome. It allows me to broadcast, no lag, and my mic works fine. guv would be my best option at this point because everything I've tried has given me nothing but trouble Thanks and I hope you guys can give me an answer. I've been at this for 2-3 days straight now. I could even go out of my way to not use Youtube and use something similar if it came down to it.

  • OSX pdf-kit vs Linux poppler or pdf/x

    - by Tahnoon Pasha
    I keep reading and hearing that the reason that there is no good pdf editing software for Linux is that the libraries are not as well developed. That is why there is no equivalent for Skim or Preview in Linux. I had a look a the pdf-kit documentation and the poppler documentation and they looked very similar to my admittedly non-technical view. Could someone explain to me why the OSX libraries (eg) are so much easier to write projects like Skim in than the linux ones. I'm not sure if the same applies to OSX projects to NVAlt, but it seems to be a common theme - I'd just like to understand what is behind the thesis that OSX is easier to code these projects in, and what would be involved in changing it. (I'm not disputing the value of Okular or Evince and the like, just noting that they don't have the richness of functionality of Skim, Preview or even things like Goodreader on the Ipad).

  • MBA versus MSIS

    - by user794684
    I am considering going back to school for my masters and I've been looking at several avenues I can take. I've been considering either an MBA or an MSIS degree. Overall I know that an MBA is going to give me a solid skill set that can help me become an executive. However they seem to be a dime a dozen these days and the University I can get into is good, but it's not exactly in the top 100 anything. My undergrad MINOR was in Business Information Systems. I'm rusty as hell, considering I haven't touched it, but an MSIS would be more in the direction of my past academic experience and seems to touch both on business management and IT. Question... With an MSIS will I just be a middleman? Will I really be an important person with a real skill set or will I merely be someone who isn't quite cut out to be a manager and who is clueless about the tech side? Is an MSIS degree going to give me a real chance to move up the pay scale quickly or am I better off learning programing, networking through another BS degree? What will give me more upward mobility career wise? An MBA or an MSIS?

  • Why are marketing employees, product managers, etc. deserving of their own office, yet programmers are jammed in a room as many as possible?

    - by TheImirOfGroofunkistan
    I don't understand why many (many) companies treat software developers like they are assembly line workers making widgets. Joel Spolsky has a great example of the problems this creates: With programmers, it's especially hard. Productivity depends on being able to juggle a lot of little details in short term memory all at once. Any kind of interruption can cause these details to come crashing down. When you resume work, you can't remember any of the details (like local variable names you were using, or where you were up to in implementing that search algorithm) and you have to keep looking these things up, which slows you down a lot until you get back up to speed. Here's the simple algebra. Let's say (as the evidence seems to suggest) that if we interrupt a programmer, even for a minute, we're really blowing away 15 minutes of productivity. For this example, lets put two programmers, Jeff and Mutt, in open cubicles next to each other in a standard Dilbert veal-fattening farm. Mutt can't remember the name of the Unicode version of the strcpy function. He could look it up, which takes 30 seconds, or he could ask Jeff, which takes 15 seconds. Since he's sitting right next to Jeff, he asks Jeff. Jeff gets distracted and loses 15 minutes of productivity (to save Mutt 15 seconds). Now let's move them into separate offices with walls and doors. Now when Mutt can't remember the name of that function, he could look it up, which still takes 30 seconds, or he could ask Jeff, which now takes 45 seconds and involves standing up (not an easy task given the average physical fitness of programmers!). So he looks it up. So now Mutt loses 30 seconds of productivity, but we save 15 minutes for Jeff. Ahhh! Quote Link More Spolsky on Offices Why don't managers and owner's see this?

  • Why do I get error, Invalid command 'PythonHandler'?

    I'm trying to deploy a Django application, but I've hit a brick wall. On Debian (latest), I've run these commands so far: apt-get install apache2 apache2-doc apache2-mpm-prefork apache2-utils libexpat1 ssl-cert libapache2-mod-python python-django I've tried adding the module manually in the Apache 2 config files, but to be honest I'm totally lost. It's totally different to Apache version 1 which I used years ago. Syntax error on line 7 of /etc/apache2/sites-enabled/000-default: Invalid command 'PythonHandler', perhaps misspelled or defined by a module not included in the server configuration I've added the following to my sites-available/default file, between the tags. <Location "/"> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE hellodjango1.settings PythonDebug Off </Location> Here's what tutorials I've used so far, without much luck: Django | How to use Django with Apache and mod_python | Django Documentation How To Install Django On Debian Etch (Apache2/mod_python)

  • Begin the Clone Wars Have!

    - by Antony Reynolds
    Creating a New Virtual Machine from an Existing Virtual Disk In previous posts I described how I set up an OEL6 machine under VirtualBox that can run an 11gR2 database and FMW 11.1.1.5.  That is great if you want the DB and FMW running in the same virtual image and it has served me well for some proof of concepts and also for some testing of different JVMs.  However I also wanted to run some testing of FMW with the database running on a separate physical machine.  So in this post I will show how to take a VirtualBox image and create a new image based on the disks from that original image. What are my Options? There is more than one way to skin a cat, or in this case to create two separate VMs that can run on different hardware.  Some of the options include: Create new virtual disk images for each new VM. Clone the existing disk images and point the new VM at the cloned images. Point the new VM at the existing snapshots. #1 is too much like hard work, install OEL twice, install a database again, install FMW again, run RCU again!  Life is too short! #2 is probably the safest way of doing things.  VirtualBox allows you to clone a disk image for use in a separate machine.  However this of course duplicates the disk and means that it is now occupying 3 times the space, once for the original disk and twice more for the two clones I would need. #3 is the most space efficient way of doing things.  It does mean however that I can only run the new “cloned” images if I have access to the original image because that is where the base snapshots reside.  However this is not a problem for me as long as I remember to keep all threee images together.  So this is the approach we will follow. Snapshot, What Snapshot? As we are going to create new virtual machines based on existing snapshots we need to figure out which snapshot to use.  We do this by opening the “Media Manager” from within VirtualBox and moving the mouse over the snapshot images until we find the snapshots we want – the snapshot name is identified in the “Attached to:” comment.  In my case I wanted the FMW installed snapshot because that had a database configured for FMW alongside the FMW software.  I made a note of the filename of that snapshot (actually I just noted the first 5 characters as that was all that was needed to uniquely identify the snapshot file). When we create the new machines we will point them at the snapshot filename we have just checked. Network or NotWork? Because we want the two new machines to communicate with each other when hosted in different physical machines we can’t use the default NAT networking mode without a lot of hassle.  But at the same time we need them to have fixed IP addresses relative to each other so that they can see each other whilst also being able to see the outside world. To achieve all these requirements I created two network adapters for each machine.  Adapter 1 was a standard NAT mapping.  This will allow each machine to get a dynamic IP address (10.0.2.15 by default) that can be used to access the external world through the VBox provided NAT gateway.  This is the same as the existing configuration. The second adapter I created as a bridged adapter.  This gives the virtual machine direct access to the host network card and by using fixed IP addresses each machine can see the other.  It is important to choose fixed IP addresses that are not routable across your internal network so you don’t get any clashes with other machines on your network.  Of course you could always get proper fixed IP addresses from your network people, but I have serveral people using my images and as long as I don’t have two instances of the same VM on the same network segment this is easier and avoids reconfiguring the network every time someone wants a copy of my VM.  If it is available I would suggest using the 10.0.3.* network as 10.0.2.* is the default NAT network.  You can check availability by pinging 10.0.3.1 and 10.0.3.2 from your host machine.  If it times out then you are probably safe to use that. Creating the New VMs Now that I had collected the data that I needed I went ahead and created the new VMs. When asked for a “Boot Hard Disk” I used the “Choose a virtual hard disk file…” link to find the snapshot I had previously selected and set that to be the existing hard disk.  I chose the previously existing SOA 11.1.1.5 install for both the new DB and FMW machines because that snapshot had the database with the RCU completed that I wanted for my DB machine and it had the SOA software installed which I wanted for my FMW machine. After the initial creation of the virtual machine go into the network setting section and enable a second adapter which will be bridged.  Make a note of the MAC addresses (the last four digits should be sufficient) of the two adapters so that you can later set the bridged adapter to use fixed IP and the NAT adapter to use DHCP. We are now ready to start the VMs and reconfigure Linux. Reconfiguring Linux Because I now have two new machines I need to change their network configuration.  In particular I need to change the hostname, update the hosts file and change the network settings. Changing the Hostname I renamed both hosts by running the hostname command as root: hostname vboxfmw.oracle.com I also edited the /etc/sysconfig file and set the correct hostname in there. HOSTNAME=vboxfmw.oracle.com Changing the Network Settings I needed to change the network configuration to give the bridged network a fixed IP address.  I first explicitly set the MAC addresses of the two adapters, because the order of the virtual adapters in the VirtualBox Manager is not necessarily the same as the order of the adapters in the guest OS.  So I went in to the System->Preferences->Network Connections screen and explicitly set the “Device MAC address” for the two adapters. Having correctly mapped the Linux adapters to the VirtualBox adapters I then set the Bridged adapter to use fixed IP addressing rather than DHCP.  There is no need for additional routing or default gateways because we expect the two machine to be on the same LAN segment. Updating the Hosts File Having renamed the machines and reconfigured the network I then updated the /etc/hosts file to refer to the new machine name add a new line to the hosts file to provide an additional IP address for my server (the new fixed IP address) add a new line for the fixed IP address of the other virtual machine 10.0.3.101      vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.2.15       vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.3.102      vboxfmw.oracle.com      vboxfmw # Added by NetworkManager 127.0.0.1       localhost.localdomain   localhost ::1     vboxdb.oracle.com       vboxdb  localhost6.localdomain6 localhost6 To make sure everything takes effect I restarted the server. Reconfiguring the Database on the DB Machine Because we changed the hostname the listener and the EM console no longer start so I need to modify the listener.ora to use the new hostname and I also need to rebuild the EM configuration because it also relies on the hostname. I edited the $ORACLE_HOME/network/admin/listener.ora and changed the listening address to the new hostname:       (ADDRESS = (PROTOCOL = TCP)(HOST = vboxdb.oracle.com)(PORT = 1521)) After changing the listener.ora I was able to start the listener using: lsnrctl start I also had to reconfigure the EM database control.  I first deconfigured it using the command: emca -deconfig dbcontrol db -repos drop This drops the repository and removes any existing registered dbcontrols. I then re-configured it using the following command: emca -config dbcontrol db -repos create This creates the EM repository and then configures and starts dbcontrol. Now my database machine is ready so I can close it down and take a snapshot. Disabling the Database on the FMW Machine I set up the database to start automatically by creating a service called “dbora”.  On the FMW machine I do not need the database running so I can prevent it auto-starting by running the following command: chkconfig –del dbora Note that because I am using a snapshot it is not a waste of disk space to have the DB installed but not used.  As long as I don’t run it, it won’t cost me anything. I can now close the FMW machine down and take a snapshot. Creating a New Domain The FMW machine is now ready to create a new domain.  When creating the domain I can point it at the second machine which is running the database.  I can potentially run these machines on two separate physical machines as long as I have the original virtual machine available to both of the physical machines. Gotchas in Snapshotting VirtualBox does not support the concept of linked machines in a network like some virtualization technologies so when creating a snapshot it is a good idea to shut both VMs down and then take a snapshot on both of them.  This is because we want to keep the database in sync with the middleware.  One way to make sure that this happens would be to place all the domain configuration files on the database server via an NFS share, this would mean that all we would need to snapshot would be the database machine because that would hold all the state and configuration. The Sky’s the Limit We have covered a simple case of having just two machines.  I have a more complicated configuration in which two machine run a RAC database off the same base OS image, and two more machines run a SOA cluster based on the same OS image.  Just remember what machine holds state and what are the consequences of taking a snapshot.

  • Charging by the hour/project

    - by thesam18888
    This is related to a question I asked earlier - How to end a relationship with a client without pissing them off? What are your obligations when charging by the hour vs charging by project? If you agree to take on a project, give a rough estimate that it might take 10 days for you to work on and charge £X per hour - are you obligated to work for free after those 10 days are up and you have still not managed to complete your project due to unanticipated issues? What if you have delivered the project but bugs are found - should you fix these bugs for free if the 10 days are up or should you charge your client? Also, for the above project, what should be the result when you start on the project, but after the 10 days for whatever reason you have to give up and tell your client that you cannot do it anymore? I realise that this does nothing to build your reputation and relationship with the client but are you obligated to pay back the money paid to you or do you just deliver the half/nearly completed source code and help them find someone else to complete it? The reason I am asking the above questions is because I am very new to freelancing and would like to know how to deal with the above situations if they ever crop up. Thanks!

Productivity depends on being able to juggle a lot of little details in short term memory all at once. Any kind of interruption can cause these details to come crashing down. When you resume work, you can't remember any of the details (like local variable names you were using, or where you were up to in implementing that search algorithm) and you have to keep looking these things up, which slows you down a lot until you get back up to speed. Here's the simple algebra. Let's say (as the evidence seems to suggest) that if we interrupt a programmer, even for a minute, we're really blowing away 15 minutes of productivity. For this example, lets put two programmers, Jeff and Mutt, in open cubicles next to each other in a standard Dilbert veal-fattening farm. Mutt can't remember the name of the Unicode version of the strcpy function. He could look it up, which takes 30 seconds, or he could ask Jeff, which takes 15 seconds. Since he's sitting right next to Jeff, he asks Jeff. Jeff gets distracted and loses 15 minutes of productivity (to save Mutt 15 seconds). Now let's move them into separate offices with walls and doors. Now when Mutt can't remember the name of that function, he could look it up, which still takes 30 seconds, or he could ask Jeff, which now takes 45 seconds and involves standing up (not an easy task given the average physical fitness of programmers!). So he looks it up. So now Mutt loses 30 seconds of productivity, but we save 15 minutes for Jeff. Ahhh! Quote Link More Spolsky on Offices Why don't managers and owner's see this?

  • How to get Facebook-Feeds in Trillian without connecting to Facebook-Chat?

    - by Protron
    I installed the trial of Trillian 5.0 Build 22 (I don't know if the version 4 Astra is any different). I successfully added my Facebook account so I can see my facebook news on Trillian and works great. The problem is that I don't want to use the Facebook-chat, and if I disconnect the Facebook-chat the rest of the facebook stuff (news, events, groups, request) also disappears. I tried by setting the Facebook status to Away; and I'm not sure if someone can chat with me if I choose that; but anyway I still have the contacts list full of people I don't want. EDIT: Maybe I wasn't clear enough about the Facebook part. And that might be why some people fell this is off-topic. But when I talk about Facebook in this question, I'm not referring to the Facebook site at any point. I'm mean the Facebook plugin of Trillian (and it's not an user plugin; it's a built-in plugin).

  • Developing geometry-based Web Services for WebLogic | Part 1 by Ronald van Luttikhuizen

    - by JuergenKress
    In a recent project we developed Web Services that expose geographical data in their operations. This blog explains the use case for the service, gives an overview of the software architecture, and briefly discusses GML as markup language for geographical data. Part 2 of this blog provides pointers on the implementation of the service while part 3 discusses the deployment on Oracle WebLogic Server. Use Case The "BAG" (Basisregistratie Adressen en Gebouwen) is a Dutch national database containing information on all addresses and buildings in the Netherlands, and is maintained by Dutch municipalities. For several object types the BAG also maintains the associated geographical location and shape; for example for premises and cities. Read the complete article here.

  • Find the source of malware?

    - by Jud Stephenson
    I have a server that was running an older version of lighttpd (1.4.19 on a freebsd 6.2-RELEASE (yea, old) machine) and google alerted me that it had found malware embedded on one of my server's pages. It just so happened to be our index page. I promptly removed the malware and started looking at server logs for how it got there. With no trace in any of the logs of the files being edited, I noticed that the index page's owner had been changed to www, which is the lighttpd user. I then concluded that some sort of veunerability must have existed for that software version and promptly upgraded to 1.4.26. Now the malware is back. I have started some pretty verbose server logging with ftp, lighttpd, and all login attempts to try and see how this script is getting in. Are their any suggestions as to other approaches to take?

  • Installed ASUS HD4670, now unable to install ANY Debian due to low memory corruption

    - by Alfabravo
    I have a desktop PC which initially had the Intel D946gzis mobo, its chipset as video controller, some RAM and so. There I installed Debian without a problem alongside WindowsXP. I've bought an ASUS HD 4670 video card, installed it on the PC and now the installed Debian does not work, while the Ubuntu live CD refuses to run no matter if I set acpi, apic on or off... it throws me some low memory corruption at position just like shown here. With normal configuration, Debian throws kernel panic (keyboard lights blinking). Anyone have faced this before? Ideas? Thanks!! (meanwhile, debian hides in a virtualbox :'( ) Edited: Tried Ubuntu 9.10 x64 (due to the fact i've a core2duo at 2GHz) and it throws a kernel-panic to me (flashing caps and num LEDs). On screen, can be read different lines with things like: ... [ 1.957161] [] rb_erase+0xd6/0x160 [ 1.957266] [] page_fault+0x25/0x30 Could it be something about this new video card having ddr3?

  • Creating an OS X Mountain Lion 10.8 OpenDIrectory database with a specific domain in mind

    - by whardier
    Mountain Lion Server has been one of the most infuriating things ever recently. Above and beyond tons of crashing I've been completely unable to do the following in a way that makes sense to both me and Apple. Name your server srv01.myoffice.domain.com Create an OpenDirectory database as a Master from scratch as dc=domain,dc=com I can rename my server temporarily (taking down vital services in the process due to the automagicliciousness) and create a new profile, however when I switch back to the original domain name the default search base for server related authentication magic is now dc=srv01,dc=myoffice,dc=domain,dc=com. I've tried everything I can think of including using slapconfig backupdb/restoredb and slaving the server off of another then promoting it. This seems rather silly and Apple shows no response to many requests to resolve this. Does anybody out there have the magic to have OpenDirectory work as it should.. being able to give it any domain you want and then having all vital services operate correctly.

  • Microsoft Test Manager error in displaying test steps caused by malware

    - by terje
    Sometimes the tool is blamed for errors which are not the fault of the tool – this is one such story.  It was however, not so easy to get to the bottom of it, so I hope sharing this story can help some others. One of our test developers started to get this message inside the test steps part of a test case in the MTM. saying “Could not load file or assembly ‘0 bytes from System, Version=4.0.0.0,……..” The same error came up inside Visual Studio when we opened a test case there. Then we noted a similar error on another piece of software – this error: A System.BadImageFormatException, and same message as above, but just for framework 2.0. We found this  description which pointed to a malware problem (See bottom of that post), that is a fake anti-spyware program called “Additional Guard”.  We checked the computer in question using Malwarebytes Anti-Malware tool.  It found and cleaned out 753 registry keys!!  After this cleanup operation the error was gone.  This is a great tool !  The “Additional Guard” program had been inadvertently installed, and then uninstalled afterwards, but the corrupted keys were of course not removed.  We also noted that this computer had full corporate virus scanning and malware protection, but still this nasty little thing still slipped through.

  • Do you need all that data?

    - by BuckWoody
    I read an amazing post over on ars technica (link: http://arstechnica.com/science/news/2010/03/the-software-brains-behind-the-particle-colliders.ars?utm_source=rss&utm_medium=rss&utm_campaign=rss) abvout the LHC, or as they are also known, the "particle colliders". Beyond just the pure scientific geek awesomeness, these instruments have the potential to collect more data than you can (or possibly should) store. Actually, this problem has a lot in common with a BI system. There's so much granular detail available in the source systems that a designer has to decide how, and how much, to roll up the data. Whenver you do that, you lose fidelity, but in many cases that's OK. Take, for example, your car's speedometer. You don't actually need to track each and every point of speed as it happens. You only need to know that you're hovering around the speed limit at a certain point in time. Since this is the way that humans percieve data, is there some lesson we should take in the design of data "flows" - and what implications does this have for new technologies like StreamInsight?

  • Stuck on Checking battery state at startup in Ubuntu, have splash screen no startup

    - by jeffhsu3
    I am running Ubuntu 10.04 LTS. When I boot up the computer it goes to the splash but there is no login screen, just the purple background and the mouse cursor. "Checking battery state" is the last line that does not have an "[OK]". When I press Ctr-alt-shift-F1 I can login and sudo stop gdm and startx. However this makes it so that the applets don't show. Error: "The panel encountered a problem while loading "OAFIID:GNOME_notificationAreaApplet" and does it for every single applet. Everything else works fine though. I get a EHCI: BIOS handoff failed twice in the dmesg as well. The laptop has intel mobile integrated graphics. UPDATE: Now my desktop has the exact same problem. Things that I have tried: Changing to GRUB_CMDLINE_LINUX_DEFAULT="i915.modeset=1 acpi=off"
