  • Is there a way to legally create a game mod?

    - by Rodrigo Guedes
    Some questions about it: If I create a funny version of a copyrighted game and sell it (crediting the original developers) would it be considered a parody or would I need to pay royalties? If I create a game mod for my own personal use would it be legal? What if I gave it for free to a friend? Is there a general rule about it or it depends on the developer will? P.S.: I'm not talking about cloning games like this question. It's all about a game clearly based on another. Something like "GTA Gotham City" ;) EDIT: This picture that I found over the internet illustrate what I'm talking about: Just in case I was not clear: I never created a mod game. I was just wondering if it would be legally possible before trying to do it. I'm not apologizing piracy. I pay dearly for my games (you guys have no idea how expensive games are in Brazil due to taxes). Once more I say that the question is not about cloning. Cloning is copy something and try to make your version look like a brand new product. Mods are intended to make reference to one or more of its source. I'm not sure if it can be done legally (if I knew I wasn't asking) but I'm sure this question is not a duplicate. Even so, I trust in the moderators and if they close my question I will not be offended - at least I had an opportunity to explain myself and got 1 good answer (by the time I write this, maybe some more will be given later).

  • Desktop forgets theme?

    - by Marcelo Cantos
    I am running Ubuntu in VirtualBox (on a Windows 7 host). Several times now, the top-level menu bar, the task bar — and seemingly every system dialog — have forgotten the out-of-the-box "Ambiance" theme they conform to when I first installed the system. Window captions still preserve the theme, but pretty much nothing else does. I have searched high and low on Google for assistance with this problem. Everything I've found suggests either running some gconf reset or deleting .gconf* .gnome* and other similar directories. I have followed all this advice and nothing works. I still get a boring Windows-95-style gray 3D look and feel. On previous occasions, after much messing around I've given up and rebooted the VM instance, and been pleasantly suprised to see the original "Ambience" theme restored throughout the UI, but invariably it disappears again some time later, usually after a reboot, so I can never figure out what I did that broke it. Here's a sample from Ubuntu's site of what I want it to look like. And here's a screenshot of my system as it currently looks. Also note that my GNOME Terminals normally have a nice purple semi-translucent look, and as can be seen from the screenshot, they are now just a solid matte white. This last time (just yesterday), trying numerous combinations all the usual tricks and rebooting several times hasn't fixed it, so here I am on SU wondering: How do I recover the out-of-the-box theme for my Gnome/Ubuntu desktop, noting that blowing away all config files — as suggested in many places online — fails to achieve this? It might help to know that it seems to fail either after I resize the VM instance, forcing the Ubuntu desktop to resize itself, or after I play around with Compiz settings. I haven't been able to figure out which of these it is, and it could be neither. Given the amount of pain I have had to go through to get things back to normal (and given that I am at a loss as to how to do so), it has proven difficult to definitively isolate the cause.

  • Installing LBP 2900 printer -> libs folders wrong?

    - by Peter Smit
    I am trying to get my Canon LBP2900 printer to work on Ubuntu 11.10 64 bit. What I have done is try to follow the steps on https://help.ubuntu.com/community/CanonCaptDrv190 So I downloaded the version 2.3 driver and tried to convert the rpm files to debian and installed them sudo alien cndrvcups-capt-2.30-1.x86_64.rpm cndrvcups-common-2.30-1.x86_64.rpm sudo dpkg -i cndrvcups-capt-2.30-1.x86_64.deb cndrvcups-common-2.30-1.x86_64.deb restarted cups and try to install the printer with lpadmin: sudo service cups restart sudo /usr/sbin/lpadmin -p LBP2900 -m /usr/share/cups/model/CNCUPSLBP2900CAPTK.ppd -v ccp://localhost:59787 -E What I noticed however that on the step with lpadmin it goes wrong with the error: lpadmin: Bad device-uri scheme "ccp" After trying to trace what has gone wrong, I think I nailed it to the fact that dpkg installed a file /usr/lib64/cups/backend/ccp instead of /usr/lib/cups/backend/ccp Checking the original rpm with archive manager shows indeed that /usr/lib and /usr/lib64 are used, with the backend/cpp file only installed in lib64. As I understand correctly, Ubuntu 11.10 uses /usr/lib32 and /usr/lib instead so the files are installed in the wrong place. Is there an automated method of converting the rpm/deb files with the wrong lib structure to one with the right lib structure for ubuntu 11.10? Or am I completely on the wrong track for getting my printer installed?

  • What is the correct way to restart udev in Ubuntu?

    - by zerkms
    I've changed the name of my eth1 interface to eth0. How to ask udev now to re-read the config? service udev restart and udevadm control --reload-rules don't help. So is there any valid way except of rebooting? (yes, reboot helps with this issue) UPD: yes, I know I should prepend the commands with sudo, but either one I posted above changes nothing in ifconfig -a output: I still see eth1, not eth0. UPD 2: I just changed the NAME property of udev-rule line. Don't know any reason for this to be ineffective. There is no any error in executing of both commands I've posted above, but they just don't change actual interface name in ifconfig -a output. If I perform reboot - then interface name changes as expected. UPD 3: let I explain all the case better ;-) For development purposes I write some script that clones virtual machines (VirtualBox-driven) and pre-sets them up in some way. So I perform a command to clone VM, start it and as long as network interface MAC is changed - udev adds the second rule to network persistent rules. Right after machine is booted for the first time there are 2 rules: eth0, which does not exist, as long as it existed in the original VM image MAC eth1, which exists, but all the configuration in all files refers to eth0, so it is not that good for me So I with sed delete the line with eth0 (it is obsolete and useless in cloned image) and replace eth1 with eth0. So currently I have valid persistent rule, but there is still eth1 in /dev. The issue: I don't want to reboot the machine (it will take another time, which is not good thing on building-VM-stage) and just want to have my /dev rebuilt with some command so I have ready-to-use VM without any reboots.

  • Integration error in high velocity

    - by Elektito
    I've implemented a simple simulation of two planets (simple 2D disks really) in which the only force is gravity and there is also collision detection/response (collisions are completely elastic). I can launch one planet into orbit of the other just fine. The collision detection code though does not work so well. I noticed that when one planet hits the other in a free fall it speeds backward and goes much higher than its original position. Some poking around convinced me that the simplistic Euler integration is causing the error. Consider this case. One object has a mass of 1kg and the other has a mass equal to earth. Say the object is 10 meters above ground. Assume that our dt (delta t) is 1 second. The object goes to the height of 9 meters at the end of the first iteration, 7 at the end of the second, 4 at the end of the third and 0 at the end of the fourth iteration. At this points it hits the ground and bounces back with the speed of 10 meters per second. The problem is with dt=1, on the first iteration it bounces back to a height of 10. It takes several more steps to make the object change its course. So my question is, what integration method can I use which fixes this problem. Should I split dt to smaller pieces when velocity is high? Or should I use another method altogether? What method do you suggest? EDIT: You can see the source code here at github:https://github.com/elektito/diskworld/

  • Advantages of Singleton Class over Static Class?

    Point 1) Singleton We can get the object of singleton and then pass to other methods. Static Class We can not pass static class to other methods as we pass objects Point 2) Singleton In future, it is easy to change the logic of of creating objects to some pooling mechanism. Static Class Very difficult to implement some pooling logic in case of static class. We would need to make that class as non-static and then make all the methods non-static methods, So entire your code needs to be changed. Point3:) Singleton Can Singletone class be inherited to subclass? Singleton class does not say any restriction of Inheritence. So we should be able to do this as long as subclass is also inheritence.There's nothing fundamentally wrong with subclassing a class that is intended to be a singleton. There are many reasons you might want to do it. and there are many ways to accomplish it. It depends on language you use. Static Class We can not inherit Static class to another Static class in C#. Think about it this way: you access static members via type name, like this: MyStaticType.MyStaticMember(); Were you to inherit from that class, you would have to access it via the new type name: MyNewType.MyStaticMember(); Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism. span.fullpost {display:none;}

  • How to use the Raring/Saucy netboot installer to install Precise?

    - by mikepurvis
    We have a Haswell motherboard with onboard ethernet controllers which are not supported in the Precise (3.2) kernel. However, we're using netboot installation, and we'd really like to stick with the LTS version. Once the Precise install is completed, we can install the linux-generic-lts-saucy package, which gets us the ethernet hardware support which is ultimately required. So, our options are: Plug in a USB-Ethernet (or even wifi) dongle, perform the install that way. Modify the Precise installer to somehow include the required driver (a udeb, or some early_command invocation?) Modify the Raring installer (3.8 kernel, which supports the device) to instead install Precise. If it's possible the third option seems like the simplest and most logical to me. Now, we are already using the precise-updates installer (Aug 2013), as opposed to the original April 2012 installer. However, the precise-updates installer still appears to use the 3.2 kernel. I'm already comfortable with preseeding and modifying the netboot initrd. So my question is, can I somehow modify the Raring/Saucy netboot initrd to instead install Precise? Thanks.

  • OOP concept: is it possible to update the class of an instantiated object?

    - by Federico
    I am trying to write a simple program that should allow a user to save and display sets of heterogeneous, but somehow related data. For clarity sake, I will use a representative example of vehicles. The program flow is like this: The program creates a Garage object, which is basically a class that can contain a list of vehicles objects Then the users creates Vehicles objects, these Vehicles each have a property, lets say License Plate Nr. Once created, the Vehicle object get added to a list within the Garage object --Later on--, the user can specify that a given Vehicle object is in fact a Car object or a Truck object (thus giving access to some specific attributes such as Number of seats for the Car, or Cargo weight for the truck) At first sight, this might look like an OOP textbook question involving a base class and inheritance, but the problem is more subtle because at the object creation time (and until the user decides to give more info), the computer doesn't know the exact Vehicle type. Hence my question: how would you proceed to implement this program flow? Is OOP the way to go? Just to give an initial answer, here is what I've came up until now. There is only one Vehicle class and the various properties/values are handled by the main program (not the class) through a dictionary. However, I'm pretty sure that there must be a more elegant solution (I'm developing using VB.net): Public Class Garage Public GarageAdress As String Private _ListGarageVehicles As New List(Of Vehicles) Public Sub AddVehicle(Vehicle As Vehicles) _ListGarageVehicles.Add(Vehicle) End Sub End Class Public Class Vehicles Public LicensePlateNumber As String Public Enum VehicleTypes Generic = 0 Car = 1 Truck = 2 End Enum Public VehicleType As VehicleTypes Public DictVehicleProperties As New Dictionary(Of String, String) End Class NOTE that in the example above the public/private modifiers do not necessarily reflect the original code

  • Mapping XFCE4/xRDP sessions to users

    - by garrilla
    I have Ubuntu 13.10 with Xubuntu Desktop - XFCE4. I'm trying to use XDRP to allow MS Windows users to login to the machine with their own user. I've been a lot around the houses with this! I've find two half-way solutions, but can't get them to work as I'd like... 1) in /etc/xrdp/xrdp.ini I set the port to -1 [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=-1 each time any user logs on they get a new session - they can never go back to their original session 2) in /etc/xrdp/xrdp.ini I set the port to 5912 (e.g) [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5912 each time any user logs on they always log on to the same session irrespective of their logon details ??) I found a mid-way solution, to create a lot of sessions by adding adding additional options in the xrdp.ini e.g. [xrdp8] name=Bob's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5913 [xrdp9] name=Jill's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5914 and so on, but he problem with this is that Jill can still log into Bob's remote session ??? Is it possible to to do what I'm trying to do? Maybe I have to use different tools?

  • How can I add a custom item to the Sound Indicator (and make it clickable more than once)?

    - by con-f-use
    The original question One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it. Edit 2 - Now a dirty DBus hack The one click problem from one edit before has now turned into a DBus problem. Basically we have to tell the sound indicator that our bogus player has terminated now. A dirty hack navigates around that problem: #!/bin/bash # This is '/home/confus/bin/toggleSpeaker.sh' notify-send "Toggle Speaker" "$(date)" qdbus \ com.canonical.indicator.sound \ /org/ayatana/indicator/service \ org.ayatana.indicator.service.Shutdown exit 0 Help from the community is appreciated as I don't have experience any with DBus whatsoever. Edit 1 - Takkat found a solution but only clickable once? For some reason the solution proposed by Takkat has the drawback that the resulting entry in indicator sound can only be clicked once per session. If someone has a fix for, than please comment or answer, you will be upvoted. Here you can see the result: I strongly suspect the issue is related to the .desktop-file in /home/confus/.local/share/application/toggleSpeaker.desktop, which is this: [Desktop Entry] Type=Application Name=toggleSpeaker GenericName=Toggle Speaker Icon=gstreamer-properties Exec=/home/confus/bin/toggleSpeaker.sh Terminal=false And here is a minimal example of the script in /home/confus/bin/toggleSpeaker.sh for your consideration: #!/bin/bash # This is '/home/confus/bin/toggleSpeaker.sh' notify-send "Toggle Speaker" "$(date)" exit 0

  • Links to C++ AMP and other content

    - by Daniel Moth
    A few links you may be interested in. This week was a big week for Microsoft with the unveiling of the developer story for Windows 8 Metro-style apps. The recorded sessions are available on channel9. Note that you can use C++ AMP in both Metro and desktop apps, and in fact even on Windows 7. Visual Studio 11 Developer Preview is now available. To download it, here is a link to a link plus context. As I previously shared, I was also speaking at BUILD on C++ AMP, and here is a direct link to that recording. Kate Gregory has started a book on C++ AMP and she has graciously shared the first 1-2 draft chapters for free online – get the link from her blog post which is also where you can leave her feedback. As Yossi Levanoni (the architect of C++ AMP), posted on our team blog, the C++ AMP article that he and I co-authored is now available at Dr Dobbs. Important reminder: Questions on C++ AMP should be posted at http://social.msdn.microsoft.com/Forums/en/parallelcppnative/threads Comments about this post by Daniel Moth welcome at the original blog.

  • MyMessageBox for Phone and Store apps

    - by Daniel Moth
    I am sharing a class I use for both my Windows Phone 8 and Windows Store app projects. Background and my requirements For my Windows Phone 7 projects two years ago I wrote an improved custom MessageBox class that preserves the well-known MessageBox interface while offering several advantages. I documented those and shared it for Windows Phone 7 here: Guide.BeginShowMessageBox wrapper. Aside: With Windows Phone 8 we can now use the async/await feature out of the box without taking a dependency on additional/separate pre-release software. As I try to share code between my existing Windows Phone 8 projects and my new Windows Store app projects, I wanted to preserve the calling code, so I decided to wrap the WinRT MessageDialog class in a custom class to present the same MessageBox interface to my codebase. BUT. The MessageDialog class has to be called with the await keyword preceding it (which as we know is viral) which means all my calling code will also have to use await. Which in turn means that I have to change my MessageBox wrapper to present the same interface to the shared codebase and be callable with await… for both Windows Phone projects and Windows Store app projects. Solution The solution is what the requirements above outlined: a single code file with a MessageBox class that you can drop in your project, regardless of whether it targets Windows Phone 8, or Windows 8 Store apps or both. Just call any of its static Show functions using await and dependent on the overload check the return type to see which button the user chose.// example from http://www.danielmoth.com/Blog/GuideBeginShowMessageBox-Wrapper.aspx if (await MyMessageBox.Show("my message", "my caption", "ok, got it", "that sucks") == MyMessageBoxResult.Button1) { // Do something Debug.WriteLine("OK"); } The class can be downloaded from the bottom of my older blog post.

  • Monitor network connectivity in WP7 apps

    - by Daniel Moth
    Most interesting Windows Phone apps rely on some network service for their functionality. So at some point in your app you may need to know programmatically if there is network connection available or not. For example, the Translator by Moth app relies on the Bing Translation service for translations. When a request for translation (text or voice) is made, the network call may fail. The failure reason is not evident from any of the return results, so I check the connection to see if it is present. Dependent on that, a different message is shown to the user. Before the translation phase is even reached, at the app start up time the Bing service is queried for its list of  languages; in that case I don't want to show the user a message and instead want to be notified when the network is available in order to send the query out again. So for those two requirements (which I imagine are common in other apps) I wrote a simple wrapper MyNetwork static class to the framework APIs: Call once MyNetwork.MonitorNetworkAvailability() method so it monitors the network change At any time check the MyNetwork.IsConnected property to check for network presence Subscribe to its MyNetwork.ConnectionEstablished event Optionally, during debugging use its MyNetwork.ChangeStatus method to simulate a change in network status As usual, there may be better ways to achieve this, but this class works perfectly for my scenarios. You can download the code here: MyNetworks.cs. Comments about this post welcome at the original blog.

  • Efficient use of Bundling

    - by ACShorten
    One of the discussions I am having with customers and consulting people is about the use of Bundling and its appropriate use. We introduced Bundling post release in the V2.2 code line to allow partners and consultants to build solutions using the Configuration Tools objects such as UI Maps, Service Scripts, Business Objects, Business Services etc and then export and migrate them as solutions. Whilst that was the original intent I have found a few teams using the facility for other data and then complaining about the efficiency or relevance of the tool. Here are a number of guidelines to help optimize the use of Bundling for your implementation: Not all objects can be bundled. Only specific objects in the product can be bundled. These are targetted at Configuration Tools objects and a select group of other objects that are required for these objects. Maintenance Objects with the option "Eligble for Bundling" set to Y (and also contains a Bundling Add BO). Add objects to the Bundle as you complete them - Bundling can have issues with sequencing objects. The best way of combating this is to add objects to the bundle as you complete them. This will help with making sure you sequence the loading of the objects as you are building them in the correct order. Remember Bundling was designed for developers and partners to deliver solutions. If you leave adding objects to a Bundle using the Bundle Export zones then you will have less control of what sequence they are applied and this can cause timing issues. Bundling takes the latest revision  - If you combine Bundling with Revision Control then the Bundling will take the latest release of the object at the time of the export operation. Bundling and Version Control products - If you use a version control tool to control your java code then you can also check in the Bundle to associate a release between code and a bundle. Bundling is quite a powerful feature of the Oracle Utilities Application Framework that allows sales, partners, consultants and customers to package and import their Configuration Tools based solutions.

  • What happened to the Journal of Game Development?

    - by Ricket
    The lengthy mission statement from its website states: The lack of game-specific research has prevented many in the academic community from embracing game development as a serious field of study. The Journal of Game Development (JOGD), however, provides a much-needed, peer-reviewed, medium of communication and the raison d'etre for serious academic research focused solely on game-related issues. The JOGD provides the vehicle for disseminating research and findings indigenous to the game development industry. It is an outlet for peer-reviewed research that will help validate the work and garner acceptance for the study of game development by the academic community. JOGD will serve both the game development industry and academic community by presenting leading-edge, original research, and theoretical underpinnings that detail the most recent findings in related academic disciplines, hardware, software, and technology that will directly affect the way games are conceived, developed, produced, and delivered. The Journal of Game Development was established in 2003. It's hard to find any information about the issues but at four issues per year, I estimate the last issue was distributed sometime in 2005 or 2006. It had a good editorial board of college professors and a founding editor from Ubisoft. The list of articles looks good. The price was reasonable. So what happened to it? Its website recently went down but you can see the last Archive.org version. The editor-in-chief is a professor at my school so I intend to ask him in person in a week or two, but I thought I'd see what you might be able to dig up about it first. Of course I will be sure to add an answer with his official word on the matter at that time.

  • How to make Unity 3D work with Bumblebee using the Intel chipset

    - by EboMike
    I have a Sony VAIO S laptop with the dreaded Optimus and finally managed to get Bumblebee to work fully on Ubuntu 12.04 so that I can utilize both the hardware acceleration of the Intel chipset as well as the Nvidia one via optirun and/or bumble-app-settings. However, the desktop effects don't work. But they should, I vaguely remember that they worked for a while before I had Bumblebee installed. This is what I get with the support test: :~$ /usr/lib/nux/unity_support_test -p Xlib: extension "NV-GLX" missing on display ":0". OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL version string: 1.4 (2.1 Mesa 8.0.2) Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: no GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no First of all, I kind of doubt that the chipset doesn't support VBOs (essentially a standard feature in GL). Neither Xorg.0.log nor Xorg.8.log show any particular errors. As for the Nvidia drivers: In order to get them to work, I had to install the 304.22 drivers (older ones wouldn't work). They clobbered libglx.so, so I reinstated the xserver-xorg-core libglx.so in its original place, moved Nvidia's libglx.so to an nvidia-specific folder and specified that folder in the bumblebee.config. That seems to work and shouldn't cause the problem I see here. For fun, I tried to use the Nvidia chipset for Unity, but that didn't fly either: ~$ optirun /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GT 640M LE/PCIe/SSE2 OpenGL version string: 4.2.0 NVIDIA 304.22 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: no GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no

  • .NET Reflector Pro T-shirt contest - and the winner is...

    - by Laila
    Three weeks ago, I kicked off a T-shirt design contest. We've been eagerly poring over the results and today, it's finally announcement time! Although many of you raced to design some great t-shirts for us, we ended up with a clear winner who came up with a nice design and an original slogan that accurately represents what .NET Reflector Pro lets you do: decompile and debug C# and VB.NET code. So, the winner is... Mandeep Sangha! Mandeep sent us the following awesome design via the Twitter account, mss_10: We liked the combination of detective and superhero elements through the magnifying glass and the slogan. Batman (possibly the most eminent of detective-superheroes?) would be proud to wear this under his suit. Mandeep will become the happy owner of a free copy of .NET Reflector Pro and an exciting box of Red Gate goodies... as well as a copy of their very own t-shirt once it's been brought to life by our printing shop! The t-shirts will bear the name of their designer, and will be made available at .NET developer events around the world, such as conferences, tradeshows and user group events. Congratulations, Mandeep! We'll be in touch to sort out the details of your prizes. But that wasn't the only great design we received. We chose three runners-up as well: Sam Beauvois: http://twitpic.com/1vvsi9 Sherwin Rice: http://www.greenwaytechno.com/img/tee-1.png Mathieu Grétry: http://blog.section9.be/public/tshirt_reflector_01.png Thanks to you all for taking part in the contest. You'll all receive a free license for .NET Reflector Pro! We'll get in touch with you individually through twitter, so that we can get you your prizes. Keep an eye out for this T-shirt - it'll soon be making its way to an event near you!

  • beginner - best way to do a 'Confirm' page? [closed]

    - by W_P
    I am a beginning web app developer, wondering about the best way to implement a "Confirm Page" upon form submission. I have heard that it's best for the script that a form POSTs to to be implemented by handling the POST data and then redirecting to another page, so the user isn't directly viewing the page that was POSTed to. My question is about the best way to implement a "Confirm before data save" page. Do I Have my form POST to a script, which marshals the data, puts in a GET, and redirects to the confirm page, which unmarshals and displays the data in another form, where the user can then either confirm (which causes another POST to a script that actually saves the data) or deny (which causes the user to be redirected back to the original form, with their input added)? Have my form POST directly to the confirm page, which is displayed to the user and then, like #1, gives the user the option to confirm or deny? Have my form GET the confirm page, which then does the expected behavior? I feel like there is a common-sense answer to this question that I am just not getting.

  • How could I change the colour of the menu font in Lubuntu?

    - by cipricus
    I use Lubuntu 12.04 and I have become obsessed with the looks of it! There is a type of themes that I especially want to use (flat, light), all related to the Elegant brit theme. On my desktop it looks like: As I want to replace the dominating orange with blue, I would prefer even more the theme Elegant Brit re-Revisited The problem is that both of them have a problem with my system tray, a white background appears: A theme that is almost identical to the orange one, but has no problem with the system tray is called Elegant Blackle. I have tried to use this one and replaced the gtk2 folder in its main folder with the gtk2 folder from Elegant Brit re-Revisited. The result is an improvement for me, as I have eliminated a part of the orange stuff with a decent blue :). The orange now appears only with the gtk3 apps, which is rather amusing. Migrating also the gtk3 folder from the blue to the orange theme would bring the sys tray problem too: it is something related to that gtk3 folder. But this is another matter. Now I have something very close to what I want. But I especially would like to have a feature that was present in the Elegant Blackle theme and now is gone as its gtk2 folder was replaced by that of the blue theme: the black font of the menus, instead of the blueish ones. Could anyone instruct me what is to be changed in the gtk2 folder of the Elegant Brit re-Revisited theme so as to make the menus look like this (like they do in Elegant Blackle with its original gtk2 folder): and not like this? : (on my display this blue is more whitish). An alternative and ideal solution would be knowing how to edit the Elegant Brit re-Revisited theme so as to remove the systray problem or, maybe easier, to edit the orange colour of Elegant Blackle theme to as to be completely replaced by the blue of the other one.

  • Acer Aspire One 725 - missing graphic card driver for Radeon HD 7290?

    - by Melon
    Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with AMD Radeon HD 7290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8... Update: OK. Another attempt. I have a fresh Ubuntu 12.10. All updates done. downloaded Catalyst 12.11 beta drivers and decided to create a package. After installing package, I have this error from /var/log/Xorg.0.log: [ 13.394] (**) fglrx(0): NoAccel = NO [ 13.394] (**) fglrx(0): AMD 2D Acceleration Architecture enabled [ 13.394] (--) fglrx(0): Chipset: "AMD Radeon HD 7290 Graphics" (Chipset = 0x980a) [ 13.394] (--) fglrx(0): (PciSubVendor = 0x1025, PciSubDevice = 0x0740) [ 13.394] (==) fglrx(0): board vendor info: third party graphics adapter - NOT original AMD [ 13.394] (--) fglrx(0): Linear framebuffer (phys) at 0xe0000000 [ 13.394] (--) fglrx(0): MMIO registers at 0xf0200000 [ 13.394] (--) fglrx(0): I/O port at 0x00003000 [ 13.394] (==) fglrx(0): ROM-BIOS at 0x000c0000 [ 13.484] (II) fglrx(0): ATIF platform detected [ 13.564] (II) fglrx(0): AC Adapter is used [ 13.565] (EE) fglrx(0): V_BIOS address 0xd00 out of range [ 13.565] (EE) fglrx(0): Failed to obtain VBIOS from Kernel!

  • SharePoint 2010 PowerShell Script to Find All SPShellAdmins with Database Name

    - by Brian Jackett
    Problem     Yesterday on Twitter my friend @cacallahan asked for some help on how she could get all SharePoint 2010 SPShellAdmin users and the associated database name.  I spent a few minutes and wrote up a script that gets this information and decided I’d post it here for others to enjoy.     Background     The Get-SPShellAdmin commandlet returns a listing of SPShellAdmins for the given database Id you pass in, or the farm configuration database by default.  For those unfamiliar, SPShellAdmin access is necessary for non-admin users to run PowerShell commands against a SharePoint 2010 farm (content and configuration databases specifically).  Click here to read an excellent guest post article my friend John Ferringer (twitter) wrote on the Hey Scripting Guy! blog regarding granting SPShellAdmin access.  Solution     Below is the script I wrote (formatted for space and to include comments) to provide the information needed. Click here to download the script.   # declare a hashtable to store results $results = @{}   # fetch databases (only configuration and content DBs are needed) $databasesToQuery = Get-SPDatabase | Where {$_.Type -eq 'Configuration Database' -or $_.Type -eq 'Content Database'}   # for each database get spshelladmins and add db name and username to result $databasesToQuery | ForEach-Object {$dbName = $_.Name; Get-SPShellAdmin -database $_.id | ForEach-Object {$results.Add($dbName, $_.username)}}   # sort results by db name and pipe to table with auto sizing of col width $results.GetEnumerator() | Sort-Object -Property Name | ft -AutoSize     Conclusion     In this post I provided a script that outputs all of the SPShellAdmin users and the associated database names in a SharePoint 2010 farm.  Funny enough it actually took me longer to boot up my dev VM and PowerShell (~3 mins) than it did to write the first working draft of the script (~2 mins).  Feel free to use this script and modify as needed, just be sure to give credit back to the original author.  Let me know if you have any questions or comments.  Enjoy!         -Frog Out   Links PowerShell Hashtables http://technet.microsoft.com/en-us/library/ee692803.aspx SPShellAdmin Access Explained http://blogs.technet.com/b/heyscriptingguy/archive/2010/07/06/hey-scripting-guy-tell-me-about-permissions-for-using-windows-powershell-2-0-cmdlets-with-sharepoint-2010.aspx

  • Double vs Single Quotes in Chrome

    - by Rodrigo
    So when you want to embed google docs on a site you are given this chunk of code: <iframe width='500' height='300' frameborder='0' src='https://docs.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AiV6Vq32hBZIdHZRN3EwWERLZHVUT25ST01LTGxubWc&output=html&widget=true'></iframe> This works fine on my site. If you edit the page, we run the new content through some filters to escape out stuff and make sure it is valid html. After the process, the link above gets converted to this: <iframe frameborder="0" height="300" src="https://docs.google.com/spreadsheet/pub?hl=en_US&amp;hl=en_US&amp;key=0AiV6Vq32hBZIdHZRN3EwWERLZHVUT25ST01LTGxubWc&amp;output=html&amp;widget=true" width="500"></iframe> This will work on every browser except for chrome. Chrome thinks I am running JS in the src. I narrowed it down to a combination of double quotes and escaped '&' symbols. If i revert one of those back to the original state, the iframe works. I work in ruby where ' and " have different behaviors. Is Chrome doing the same thing? Is there a way to turn that off?

  • JDK 7 Feature Complete Milestone Reached

    - by Henrik Ståhl
    The JDK 7 project has reached Feature Complete (FC). This means that development and QA have finished all planned feature and test development work in the release and are moving the focus to testing and bug fixing on all supported JDK 7 platforms. This is a major step towards JDK 7 General Availability (GA) and implies that we are tracking close to the plan published on openjdk.java.net. (The original plan was FC on 12/16. We hit this less than a week late, but verifying that everything was done in time took a couple of weeks due to the intervening holidays.) The definition of the FC milestone allows for exceptions to be integrated later. There are very few such exceptions in the project, the most prominent being updated JAXP/JAXB/JAX-WS and integration of the enhanced JMX agent from JRockit. Our project management does not expect the exceptions to have any negative impact on the release plan. The project may still be delayed if the Expert Groups for the JSRs included in Java SE 7 (203, 292, 334, 336) decide to introduce changes which cannot be accomodated within the existing schedule. Apart from that caveat, Oracle remains confident with the published plan.
