How to install rgdal on Ubuntu 12.10?

- by radek

I'm strugling to install rgdal library on Ubuntu 12.10. Installation from within R results in error: Error: gdal-config not found The gdal-config script distributed with GDAL could not be found. If you have not installed the GDAL libraries, you can download the source from http://www.gdal.org/ If you have installed the GDAL libraries, then make sure that gdal-config is in your path. Try typing gdal-config at a shell prompt and see if it runs. If not, use: --configure-args='--with-gdal-config=/usr/local/bin/gdal-config' with appropriate values for your installation. ERROR: configuration failed for package ‘rgdal’ * removing ‘/home/rdk/R/x86_64-pc-linux-gnu-library/2.15/rgdal’ Warning in install.packages : installation of package ‘rgdal’ had non-zero exit status R-sig-Geo, this two SE questions and other websites pointed me to the requirements of libgdal1-dev. But when I tried sudo apt-get install libgdal1-dev I end up with another error message Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgdal1-dev : Depends: libgdal-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. Again - when I try to install libgdal-dev another dependencies error shows up The following packages have unmet dependencies: libgdal-dev : Depends: libgeos-dev but it is not going to be installed Depends: libspatialite-dev but it is not going to be installed Again trying libgeos-dev gives message: Depends: libgeos-c1 (= 3.3.3-1.1) but 3.3.3-2~precise2 is to be installed E: Unable to correct problems, you have held broken packages. and libspatialite-dev: Depends: libspatialite3 (= 3.1.0~rc2-1ubuntu1) but 3.1.0~rc2-2~precise1 is to be installed Is there any way to tame those dependencies and have rgdal running in Ubuntu?

Deleting a row from self-referencing table

- by Jake Rutherford

Came across this the other day and thought “this would be a great interview question!” I’d created a table with a self-referencing foreign key. The application was calling a stored procedure I’d created to delete a row which caused but of course…a foreign key exception. You may say “why not just use a the cascade delete option?” Good question, easy answer. With a typical foreign key relationship between different tables which would work. However, even SQL Server cannot do a cascade delete of a row on a table with self-referencing foreign key. So, what do you do?…… In my case I re-wrote the stored procedure to take advantage of recursion: -- recursively deletes a Foo ALTER PROCEDURE [dbo].[usp_DeleteFoo] @ID int ,@Debug bit = 0 AS SET NOCOUNT ON; BEGIN TRANSACTION BEGIN TRY DECLARE @ChildFoos TABLE ( ID int ) DECLARE @ChildFooID int INSERT INTO @ChildFoos SELECT ID FROM Foo WHERE ParentFooID = @ID WHILE EXISTS (SELECT ID FROM @ChildFoos) BEGIN SELECT TOP 1 @ChildFooID = ID FROM @ChildFoos DELETE FROM @ChildFoos WHERE ID = @ChildFooID EXEC usp_DeleteFoo @ChildFooID END DELETE FROM dbo.[Foo] WHERE [ID] = @ID IF @Debug = 1 PRINT 'DEBUG:usp_DeleteFoo, deleted - ID: ' + CONVERT(VARCHAR, @ID) COMMIT TRANSACTION END TRY BEGIN CATCH ROLLBACK TRANSACTION DECLARE @ErrorMessage VARCHAR(4000), @ErrorSeverity INT, @ErrorState INT SELECT @ErrorMessage = ERROR_MESSAGE(), @ErrorSeverity = ERROR_SEVERITY(), @ErrorState = ERROR_STATE() IF @ErrorState <= 0 SET @ErrorState = 1 INSERT INTO ErrorLog(ErrorNumber,ErrorSeverity,ErrorState,ErrorProcedure,ErrorLine,ErrorMessage) VALUES(ERROR_NUMBER(), @ErrorSeverity, @ErrorState, ERROR_PROCEDURE(), ERROR_LINE(), @ErrorMessage) RAISERROR (@ErrorMessage, @ErrorSeverity, @ErrorState) END CATCH This procedure will first determine any rows which have the row we wish to delete as it’s parent. It then simply iterates each child row calling the procedure recursively in order to delete all ancestors before eventually deleting the row we wish to delete.

Ubuntu doesn't load, can't even open a terminal to type commands, even after boot repair

- by Sky

When I start Ubuntu I only get my desktop picture and am unable to open a terminal to type any commands. When I try a Guest session all I get is a red Ubuntu backdrop, nothing else. I tried boot repair but no improvement. Summary information following boot repair: http://paste.ubuntu.com/8109809/ I can paste some of it here if someone can tell me which part of it is relevant. This all occurred after I tried to remove compizconfig (which I might not have completed), because it's been using up my CPU (running at 50-60% with compiz at the top in System monitor. My laptop has been running very slow since installing Ubuntu so I've been trying to fix that, also website videos play slow and the startup of Ubuntu has been faulty. I also installed a proprietory Nvidia driver (304) before this launcher issue occurred, in an effort to fix my video problem (didn't help anything). Laptop is Dell 620m with Intel Core 2; 1.83GHz, 2 GB RAM, Ubuntu 14.04 (new to Linux); 66GB Ubuntu partition. Everything works fine on the small XP partition of my laptop, but I've moved all my files to the larger Ubuntu portion. I wanted to try some answers I found to similar questions but they all seem to involve commands in a terminal and I can't open a terminal. How can I get the launcher back, along with access to my programmes etc? Thank you for any help.

Suddely internet is not accessible

- by user189708

I am going crazy here. One day everything was working fine. I turned pc off and went to sleep. Next day turn pc on and cannot access internet (from any browser). The situation is: I cannot open any webpage from browser (tried Firefox and Epiphany) and cannot receive emails in thunderbird. BUT if I run firefox from console as sudo, I can use it as usual. I can access Skype and pretty much any other network stuff (like installing software with apt-get etc.), also if I use Astrill VPN software I can access webpages even running without sudo. I haven't install any software or anything like that for several days = I have not a clue what could cause this. Just by the way, other Win PC in our home has no issue. Here is what I have tried to fix this: I have tried to restart my pc, router, modem - multiple times I have tried to change permissions to my firefox profile I have tried to completely re-install firefox and start with blank profile, thus no addons I have tried to change /etc/resolv.conf to an IP of my router (it was 127.0.1.1) I have tried to change my hostname (from tomino-NB to tominoNB) I think I might try even more stuff. None of it works. Can someone please try to help me. Thank you UPDATE 1: I have tried this: Removing resolv.conf - Didn't help Also "ping" and "dig" commands cannot resolve host UPDATE 2: I have tried to edit nameservers in resolv.conf but still no effect. I can ping router as well as I can ping outside IP. So definitely just some DNS issue. Is it possible that something is rewriting path to resolv.conf and using different file? UPDATE 3: I have just restarted PC and everything works now... resolv.conf went back to nameserver 127.0.1.1 . I have no clue what happened that it works again...

Fresh install of Ubuntu 12.10 won't boot on Asus X101CH Eee PC

- by Najdmie

I did a fresh install of Ubuntu 12.10 in my Asus X101CH Eee PC, using a live usb which I made using startup disk creator, replacing Ubuntu 12.04. The installation ran smoothly, but when I boot, it goes to a purple screen for a second, then a lot of text like the following shows up in sequence: Starting crash report submission daemon [OK] Starting CPU interrupts balancing daemon [OK] Stopping save kernel messages [OK] _ And the cursor just keeps blinking for hours. I can't log in. Pressing Alt + F2 did not bring me to console mode. I thought it might be a partition problem so I formatted the whole disk, by creating a new partition table using gparted in Ubuntu 12.04 live USB. I noticed that I can't try Ubuntu using 12.10 live USB either; it just went to a blank screen when I hit the 'try ubuntu' button. But the same problem arose. I even changed the pen drive for the live USB a couple of times. I happened to know that the Intel Atom N2600 Cedar Trail CPU in my computer is not well supported in Linux, I managed to install its drivers in Ubuntu 12.04, although the computer went blank during the installation.

XNA CustomModelAnimationSample problem

- by Mentoliptus

I downloaded the official tutorial from:CustomModelAnimationSample It works fine but when I try to replicate it in my project, it fails to load the Tag property in my model. Is found that the probelm is in the line: skinnedModel = Content.Load<Model>("DudeWalk"); This line loads the model from the DudeWalk.fbx file and with the custom SkinnedModelProcessor. It loads the animations data in the model. After the line the Tag property is full. I stepped into the method and it went to the custom ModelData class. I copied everything from the projects CustomModelAnimationWindows and CustomModelAnimationPipeline to my solution and set all the references. I tried the same line of code and couldn't step in the method. It called the default method or model constructor and after the line the model's Tag propetry was null. I have to load the model through my custom SkinnedModelProcessor class, but how I tell the game to use this class? In the tutroail CustomModelClass the line is changed to: model = Content.Load<CustomModel>("tank"); So I assumed that I have to set the generic type to a custom model class, but the first example works without it. If anyone has some useful advice or some other helpful link, I'll be happy to try it.

PeopleSoft 8.52 iPad Certification

- by Dave Bain

One of the real gems in the PeopleTools 8.52 release is the certification of PeopleSoft applications running in the Safari Browser on an iPad. It is nice that PeopleSoft is not constrained by technology like Adobe Flex/Flash, so announcements like this "Adobe drops plans for mobile Flash support" do not limit our mobile solution to custom mobile development. There are parts of PeopleSoft applications that operate better on iPads than others. One of the best is Workcenters. Workcenters were new to PeopleTools 8.51 and we are starting to see more and more adoption of them. Workcenters are roll based landing pages that eliminate difficult navigation by providing access to most links, pages, and reports a user in a role needs. One of the nicest I’ve seen is the Supply Manager Workspace. Here are some links to screenshots of what a WorkCenter looks like on an iPad: Here's the standard PeopleSoft Login Page The Supply Manager Workspace looks great full screen on an iPad iPad has a great user interface to zoom, here's a screenshot of an upclose view of an analytic. Touch one of the analytics and it drills into the details. Go ahead and give it a try. WorkCenters and Dashboards are starting to show up across applications. For a quick one to try, navigate to the PeopleTools->Integration Broker->Integration Network WorkCenter. It’s new in PeopleTools 8.52.

Trying to make ZeroRadiant work on Lubuntu 11.10

- by maniat1k

I'm looking to use ZeroRadiant to work on ubuntu, it's to create maps on urban terror, I know that works on windows and mac. I found this HOWTO but could not make it work. I've got stock on this when I do. ~/ZeroRadiant-src$ scons target=radiant,q3map2 config=release at the end shows me this: collect2: ld returned 1 exit status scons: *** [build/release/radiant/radiant.bin] Error 1 scons: building terminated because of errors. there's a note on the how to that says: If you get other errors, you may try asking for help in the GtkRadiant IRC channel, which is listed on the main ZeroRadiant page. the page does not there and I could find that IRC channel. EDIT thanks to @jokerdino in the chat sow me this If you have the proprietary NVIDIA driver installed and you get the following error when executing the build target above: /usr/bin/ld: cannot find -lGL collect2: ld returned 1 exit status scons: *** [build/release/radiant/radiant.bin] Error 1 scons: building terminated because of errors. then you should install one of the nvidia-glx-dev* packages as mentioned above in Step A, then try to execute the main build target to compile GtkRadiant again. I don't have nvidia; I do have ATI AMD Radeon HD 6320, and looks like it works. GL_VERSION: 4.1.11251 Compatibility Profile Context GL_VENDOR: ATI Technologies Inc. GL_RENDERER: AMD Radeon HD 6320 Graphics I'm think I do have video issues but.. how do I detect this? how can I continue?

jungledisk 3.16 doesn't launch

- by Angelo

Has anyone had success with jungledisk 3.16 on ubuntu 11.10? I installed it from the .deb file provided by jungledisk. The install goes fine, but I can't get the "jungle disk desktop" app to launch. It appears in the dash search bar, but doesn't launch or do anything upon selecting it. When I try the command line, I get the following... me@myComputer:~$ jungledisk -V -f Verbose mode enabled Shutting down... me@myComputer:~$ What's the deal here? Anybody else experience this? Does anyone have suggestions for what to try? I opened up a help-ticket with jungledisk, but they just asked me for which ubuntu version and which gui I was using and then went silent. I've used jungledisk since 2008 and had no problems. It is sad that it is not working on the new ubuntu for me. Should I just quit them and use dropbox or one? (those seem to be working)

Suspend/resume issue hp envy m6

- by aikeru

:) I just installed Ubuntu 13.10 on my HP envy m6. When I press the "power" button and select to suspend, it looks like it goes to sleep (power light flashing, as expected). When I press the power button to wake it (or anything else), it stops flashing and goes solid (as it should) but the screen is black. I tried CTRL+ALT+F1 but nothing seems to happen. Is there something I can do to get Ubuntu to resume from suspend? EDIT: I tried getting any updates for Ubuntu as well as updating my BIOS. Neither seems to have any effect. EDIT: Tried the 2nd script from Ubuntu 12.04 LTS suspend fix and it seemed to have no effect. Tried the 1st script and now I can't seem to suspend at all - Ubuntu seems to try to suspend and then immediately goes to the password prompt. With some combination of things I seem to be able to get a new crash, though, involving wpa_supplicant. I allowed it to submit feedback. My WiFi seems to be working fine (I assume this is what WPA is). EDIT: I know this is 'askubuntu', but I did try latest Linux Mint / Cinnamon. Results were exactly the same (black screen, power light solid after waking up - just as before, I can make it reboot by mashing CTRL+ALT+DEL but CTRL+ALT+F1/etc. doesn't work). Trying Ubuntu 12.04 next. EDIT: Ubuntu 12.04 WORKS! At least it seems to with a quick test. Came right back up after suspend. If I don't have any other problems and no answers are suggested, I'll make my own answer and accept it. Maybe someone can use this information to help troubleshoot the real issue. Would be nice to be on the latest version... but suspend would've been a deal-breaker for me. Hope this info helps someone.

Can't change settings for Mobile Broadband Dongle - Button is greyed out

- by Ross LIndsey

I was with VirginBroadband.com.au (Australia). My huawai 3G Dongle was working great on Ubuntu, However I have changed ISP's. I unlocked the modem, and put in the new SIM. I have tested this in my Windows PC and it connects to the new (Optus) Network A-OK and it all works. When I put this dongle (the same one that was working fine in Ubuntu) into that same Ubuntu Netbook it simply won't connect. When I try to go into the dialog to try and add or change settings the button to change or update settings is greyed out, I can't select it. Apparently since this dongle was already recognized the Broadband Setup Wizard won't start, and I have no idea how to get it to start (presuming it has the ability to configure an already recognized dongle). What do I have to do to either enable the ability to change the configuration for this setup, or to blow away the one that is set up so the Broadband Wizard will re-start and let me configure a new one. Can anyone provide simple instructions for doing this? I'm using Ubuntu with the Cinnamon Desktop

How to make Box2D bodies automatically return to a initial rotation

- by sm4

I have two long Box2D bodies, that can collide while moving one of them around with MouseJoint. I want them to try to hold their position and rotation. Blue body is moved using MouseJoint (yellow) towards the Red body. Red body has another MouseJoint - Blue can push Red, but Red will try to return to the start point thanks to the MouseJoint - this works just fine. Both bodies correctly rotate along the middle. This is still as I want. I change the MouseJoint to move the Blue away. What I need is both bodies return to their initial rotation (green arrows) Desired positions and rotations Is there anything in Box2D that could do this automatically? The MouseJoint does that nicely for position. I need it in AndEngine (Java, Android) port, but any Box2D solution is fine. EDIT: By automatically I mean having something I can add to the object "Paddle" without the need to change game loop. I want to encapsulate this functionality to the object itself. I already have an object Paddle that has its own UpdateHandler which is being called from the game loop. What would be much nicer is to attach some kind of "spring" joint to both left and right sides of the paddle that would automatically level the paddle. I will be exploring this option soon.

What do I need to know to design a language and write a interpreter for it?

- by alFReD NSH

I know this question has been asked and even there are thousands of books and articles about it. But the problem is that there are too many, and I don't know are they good enough, I have to design a language and write a interpreter for it. The base language is javascript (using nodejs) but it's ok if the compiler was written in another language that I can use from node. I had done a research about compiler compilers in JS, there is jison (Bison implementaion in JS), waxeye, peg.js. I decided to give jison a try, due to the popularity and its being used by coffee script, so it should be able to cover my language too. The grammar definition syntax is similar to bison. But when I tried read the bison manual it seemed very hard to understand for me. And I think it's because I don't know a lot of things about what I'm doing. Like I don't what is formal language theory. I am experienced in Javascript (I'm more talented in JS than most average programmers). And also know basic C and C++ (not much experience but can write a working code for basic things). I haven't had any formal education, so I may not be familiar with some software engineering and computer science principles. Though everyday I try to grasp a lot of articles and improve. So I'm asking if you know any good book or article that can help me. Please also write why the resource you're suggesting is good. --update-- The language I'm trying to create, is not really complicated. All it has is expressions (with or without units), comparisons and logical operators. There are no functions, loops, ... The goal is to create a language that non-programmers can easily learn. And to write customized validations and calculations.

Overlap of the variable in mysql, my column are set to my query result

The question is not clear , let me clarify it: try{ $sql = ' SELECT UserID <==== (***********Used here for query ******) FROM user WHERE Rights != ?'; $stmt = $conn->prepare($sql); $stmt->execute(array('admin')); $result= $stmt->fetchAll(); } catch(PDOException $e) { die ($e->getMessage().'<a href="add.php"> Back</a>'); } foreach ($result as $set) { if ($set['UserID']==$_SESSION['username']) $rights='edit'; else {$rights=$_POST[$set['UserID']];} if (($rights != 'default' || $set['UserID']==$_SESSION['username']) && $_POST['public']==0 ) { $user=$set['UserID']; try { $query="INSERT INTO user_list(UserID <==== (***********Used here for insert ******),ListID,UserRights) VALUES ($user,$lastID,$rights)"; $stmt = $conn->prepare($query); $stmt->execute(); } catch(PDOException $e) { die ($e->getMessage().'<a href="add.php"> Back</a>'); $conn->rollBack(); } } } As you can see the UserID is a query result but it is also the column i need to insert, so when i insert into the table it will casued an error SQLSTATE[42S22]: Column not found: 1054 Unknown column 'UserA_ID' in 'field list' because the column is modify by my query result from: $query="INSERT INTO user_list(UserID,ListID,UserRights) VALUES ($user,$lastID,$rights)"; to: $query="INSERT INTO user_list(query_result_id,ListID,UserRights) VALUES ($user,$lastID,$rights)"; How to fix it ?Thank you.

How to build the mainline kernel source package?

- by Maxime R.

Ubuntu kernel PPA only provides linux-headers*.deb and linux-image*.deb packages. How can I build the corresponding linux-source*.deb package ? Context: I'm currently running Ubuntu 11.10 with the mainline kernel (3.2 rc6 now) to get a better support for my sandybridge IGP (Dell E6420 laptop with intel i5-2520M CPU). Appears, i'd like to install this touchpad driver, ALPS touchpads being badly supported (see previous link bug report), while waiting for upstream support in kernel version 3.3. Problem is, DKMS keeps complaining about not finding the full kernel source: Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed. Appears I may not need the full source but I'd still like to try having it installed to see if it solve my problem. What I tried : Uncompressing the kernel.org source archive in /usr/src/. DKMS still complaining. Manually updating the kernel source package with uupdate and the mainline source package like explained here. Did not succeed. Manually building the linux-source package following @roadmr and @elmicha instructions. I eventually succeeded to build it but DKMS still complained about the missing source. At last I noticed an error I did not catch in the first place while reinstalling the kernel headers. Appears the .deb I got may have been corrupted, downloading it again did the trick :) Alas, while DKMS agreed to compile the module i ran into the following error which appears to have already been reported. This issue isn't yet solved but I won't try to because of the following: in the end I decided to test the precise kernel version 3.2-rc6 through the xorg-edgers ppa which appears to be correctly patched: it works. Nevertheless, it might still be of some interest to know how to build the mainline linux-source package as the Ubuntu Kernel Team doesn't provide it. Not to mention that I learned a lot in the process ^^

Ubuntu won't suspend anymore, but it did upon install.

- by Bruce Connor

I fresh installed Ubuntu 10.10 back when it came out, and my laptop was suspending fine. All of a sudden, I can't get my laptop to suspend anymore. It's an HP Pavilion dv2-1110, but I don't think it's a hardware issue, here's why: It suspended fine upon first install. I haven't installed any new kernels since then, but I have installed tons of packages, so it's probably a package. The suspend and hibernate options disappeared from the shutdown menu. If I press my keyboard's suspend button (or if I close the lid) I get the following message: If I try the command pmi action suspend, I get the error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files. If I try the command echo -n mem > sudo /sys/power/state I get absolutely no output and no visible effect. What might be causing this behavior? I thought a list of installed packages might be useful, but it's huge and I don't know how to post it here in collapse/expand mode or something. EDIT:Just in case someone asks, none of the installed packages are kdm or anything like that (which would justify the lack of options in gnome's shutdown menu).

What is a good toy example to teach version control?

- by janos

I am looking for practical examples to use when teaching version control. Breaking down the material to basic concepts and providing examples is an obvious way to teach version control, but this can be very boring, unless the examples are really practical or interesting. One idea I have is customizing a wordpress theme. I use wordpress a lot and no theme is ever perfect, so I typically just put the theme directory in version control using any dvcs and start recording changes. The problem with this example is that not many people in the audience may be familiar with wordpress, let alone have shell access to a wordpress site to try out the commands. Preparing a mock site and giving access to everyone is also not an option for me. I need a "toy example" that can be interesting to a broad audience of software developers, and something they can try on their own computers. The tutorial will use a dvcs, but the practical example I'm looking for is only to teach the basic features of version control, ignoring the distributed features for the moment. (Now that I think of it, instead of a mock site, a customized live cd might do the trick...) Any better ideas?

Intel graphic chipset and NVIDIA Geforce GTX560

- by antoine

I have an NVIDIA Geforce GTX560 with two video projectors and I would like to use the onboard Intel Graphic Chipset to plug an additional monitor. I saw the question : How can I use both Intel onboard and Nvidia graphics at the same time? but the answer is so short that I was not convinced. My motherboard (GIGABYTE GA-H61M-D2P-B3 (rev. 1.0)) equipped with Intel H61 Chipset allow shared memory between onboard and PCIe cards. And Windows 7 allow me to use the three outputs thanks to Intel's driver. I'm able to use the onboard graphic card but without graphical interface for now. I think i need intel driver for that. But I would like to know if I can setup my displays in xorg.conf with something like : Section "Device" Identifier "Device0" Driver "intel" EndSection Section "Device" Identifier "Device1" Driver "nvidia" EndSection Section "Device" Identifier "Device2" Driver "nvidia" EndSection Does anyone have successfully setup something like that ? Or should I burn my head experimenting it by myself ? Or is there any good reasons to discouraged me to try ? Thanks for your help. Antoine PS : i'm using Ubuntu 10.10 for now, but I could switch to another version. PS2 : i also read this : Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10? which doesn't tell me more about the possibilities to use Intel Graphic and Nvidia at the same time EDIT : according to that : Can not get Dual Monitors to work on Different GPUs, I should be able to run two Xserver one on Intel the other on Nvidia. I will try and post the result here.

I have been looking all over the web, and tried every suggestion I found to get the nvidia drivers working on my computer with Ubuntu Gnome 14.04, with no luck. Every time I install a driver or choose to use the driver from addition drivers, when I reebot, I cannot log in again. It gets stuck at the logo screen. I need to go to the ALT + CTRL + F1 to purge all nvidia traces so I can get back. Is it possible to install the new nvidia drivers? I just upgraded from 13.10 to 14.04, I have an Asus N550VJ which has hybrid graphics with Intel 4000 / Nvidia 750M What Im looking for is to try the primus functionality to disable the discreet card and enable it whenever I want to play or run heavy graphic stuff. When I was in 13.10 I was using bumblebee, but, since, the nvidia prime is supposedly mature enough, I wanted to try it. Is this possible for Ubuntu Gnome 14.04. I read there was a bug with gdm, but also, saw that it was already fixed. Thank you very much for your help. Im not that well versed in linux.

Unable to use Maya animation with scripts when imported to Unity

- by keshk

I am testing to import Maya animation over to Unity. I set up a simple cylinder with 2 bones and an IK handle. Made a simple animation where the cylinder bends and goes back to straight position over 24 frames. Following that, I selected everything and baked, all bones,ik,(animation by selecting all at the graph editor) and even the cylinder. I saved the scene and then select all and export as FBX with animation and bake checked. In unity imported it and at the preview able to see the animation. When I load the model into scene and play (after assigning the controller), able to see animation too. But now when I try to script it and control the animation, nothing happens. Even to test, I tried the following under the Update method. if(animation.isPlaying) Debug.Log("Animation Works"); else Debug.Log("Animation not working"); The bool doesn't even return true nor false. My animation is called "bend", thus just for try I did the following and nothing happens. animation.Play("bend"); Can please advice based on my steps, am I missing something. Do I need to add the controller or is that an unnecessary step? Did I screw up on the Maya part or the Unity part. Thanks for help.

grub workaround for cannot find UUID in dual boot system fails and now grub won't boot anything

- by keepitsimpleengineer

New clean install of x86 11.10 desktop. Dual boot with windows XP and Linux on separate drives. After install grub will not boot Windows, but by changing boot drive boots fine. When I go to fix this I find from http://bootinfoscript.sourceforge.net/ and a link to http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:search my problem, the message on the grub boot error screen: error: no such device: 6??????? So I follow the Step2 and compare the output of: sudo blkid and sudo nano /boot/grub/grub.cfg The UUIDs in both match for the Windows drive, so I do the fix in Step 4 "remove the search lines for …" in /usr/lib/grub/grub-mkconfig_lib, commenting out the three lines as before? # if fs_uuid="`${grub_probe} --device ${device} --target=fs_uuid 2> /dev/null`" ; then # echo "search --no-floppy --fs-uuid --set ${fs_uuid}" # fi I run sudo update-grub and check /etc/default/grub.cfg and see that it now identifies the Windows partition not by UUID, which I suppose is the workaround. But now when I try to boot 11.10 Desktop, I get: error: no such partition… … and when I try to boot Windows, I get: error: invalid signature. So Now, how do I fix this… The boot problem and find a workaround that works?
