• Where can I find a collection of photorealistic scenes? [on hold]

  - by emchristiansen

  Where can I find a collection of 10-100 3D scenes with photorealistic levels of detail? For example, the scene rendered here contains photorealistic detail. Note I want the underlying object models, textures, etc, not final renderings. I'll be using these scenes to test a computer vision idea. BTW, this is a reposting of this question. I wasn't able to find a Stack Exchange site that is perfectly suited to the question, but as this is a modeling and rendering question, I'm hoping it is a good enough match for the venue.

• I've got two technical degrees but little in the way of experience. How do I get into programming? [closed]

  - by Neonfirelights

  I'm looking for a job, I want to break into programming. I'm looking for the right sort of role and the right place to look for it; I would really appreciate input from someone with industry experience. I've got an excellent academic record: BSc Physics (2:1), MSc Computer Graphics, Vision and Imaging (expecting Merit) from two world ranking universities. I have advanced technical knowledge of C/C++ and Matlab and experience working with C# and VB.NET. Unfortunately I don't have much in the way of commercial experience; unlike a lot of people I know my under-graduate didn't come with a sandwich placement. Where can I go to break into the software industry?

• Resume upgrade to 13.10

  - by DmitryR

  I had 13.04 and started to upgrade to 13.10. But the computer hanged and I rebooted it. I did instructions from How do I resume a release upgrade/update? Now OS launches, but I upgrade is incomplete: there is no panels in Unity (just a background with some files on Desktop). I think that some post-install scripts didn't launch. Please help me with this trouble. P.S. Or how can I completely reinstall unity (with all of the dependencies)? My be it helps. ubuntu@ext:~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=13.10 DISTRIB_CODENAME=saucy DISTRIB_DESCRIPTION="Ubuntu 13.10" ubuntu@ext:~$ sudo do-release-upgrade Checking for a new Ubuntu release No new release found

• When I boot it says "No any drive found" and turns off after upgrade from 9.10 to 10.04

  - by user797582

  I did an upgrade on the weekend from Ubuntu 9.10 to 10.04 (karmic to lucid). Now, when I restart my computer, it goes through the regular load screen showing my P5K Asus motherboard, just like before but instead of showing the Ubuntu load screen, it tries to start grub but fails and then says "No any drive found" and the screen goes black. I've tried changing the drive configuration in the BIOS to AHCI or RAID and that didn't work. I've tried disabling JMICRON but to no avail. I'm running out of options here. Any advice?

• What is the sudo password after I deleted the password for the user?

  - by Ubuntunewbie

  To have an easier access to the computer I deleted the user's password so it is blank. But now I'm still asked to type in a password for sudo actions such as installing programms, etc. I know that this belongs to Ubuntu's outrageous security policy (which is why I use Ubuntu in the first place..) but I don't have any password to enter any more!! The old user password is not accepted and anything else (like just hitting enter) doesn't work either. I already tried the recovery mode (root shell) way passwd USER< but it replied that it can't access the password or it has no authority. Thanks in advance for your help!

• Can't connect to or search wifi

  - by Mark

  I just installed the latest version of Ubuntu, I think it was 13. Something. Anyway I got it running and now I've been trying to connect to my wifi. No matter where I go I don't see an option for wifi. I looked on the computer and found some commands to use in terminal to run a scan for wifi networks but all of them returned the error "interface doesn't support scanning" if anyone could help that would be great...I can't do anything without wifi! Also I'm new to this so if you could give step by step directions that would help a lot. Thanks!

• Dual boot w/ windows 7

  - by Aduff

  So my PC had windows XP and Win 7 on it and I went into the XP partition and installed Ubuntu 12.10 over it being sure to use 90% of the XP partition for the / mount and 10% for the swap. It installed but when I boot the computer it doesn't give me the option of choosing between 7 or Ubuntu, just booting right to the Linux distro. Should I have installed it in 7 over the XP partition? I can see the drive in Ubuntu that contains all the 7 files. How can I recover my 7 access?

• Make recovery disk for customers

  - by alexander7567

  I hear about other computer shops that sells customers recovery disks that they have created. I'm assuming all that they do is make a image and uses an automation script that allows this to be done. I have seen where clonezilla does this, but it has to be the same HDD size or they might have problems down the road. Is there any other freeware that I could do this with that allows you to use on any size disk. Ghost is really good for this because it automatically fills up empty space with the partition and never needs any user input or "Expert Mode" like clonezilla. But it is not freeware.

Also I recently tried to lock my computer,going to the power menu in the top right corner and hitting lock,it does not do anything,I am still on the desktop..(just tried crtl alt l to lock,it does work) but not the way i did it though,but that is not important to me ,I need the password prompt after suspend.. Password prompts works only when booted from a shutdown...

• In some games, we just let the main() loop be the Player object or Table object?

  - by ????

  I was thinking that let's say if there is a game of Blackjack or MasterMind, then we should have a class called Dealer or ComputerPal, which is how the computer interact with us (as a dealer for Blackjack or as the person giving hints for MasterMind). And then there should be a Player object, and the way to play one game is aPlayer.playGame but I noticed that a book was just using the main() loop to act as the player (or as the Controller of the game), calling the Dealer methods to dealer the cards, ask for player's action, etc... 1) Is this just a lazy way to model all the proper objects? 2) If more objects are to be added, who should call the aDealer.dealCards and then ask for aPlayer.askForAction? (because it is strange to let the Player handle all the logical steps). Should there be a Table object that handle all these logic and then to play one round of game, use aTable.playGame? What is a good object design for such game?

• "Adding Esperanto circumflexes (supersigno)" option has no effect

  - by Gardel

  I'm used to use the keyboard layout option to type the accentuated characters in Esperanto. This option is in System Settings Keyboard Layout Options Adding Esperanto circumflexes (supersigno) To the corresponding key in a Qwerty keyboard. It worked great but since I upgraded to Ubuntu 12.04, this option has no effect. I'm using Ubuntu in French with the keyboard layout French (variant) and Gnome-shell. I tested on another computer with Unity and there is the same issue. Is it a known issue? I did not find anything about it…

• NetworkManager refuses to manage my WLAN interface

  - by user104167

  I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C. The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly. Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot. Therefore I edited /etc/NetworkManager/NetworkManager.conf to set: [ifupdown] managed=true When I rebooted NetworkManager, the problems started: - The NetworkManager tray applet changed from saying device not managed to device not ready - I lost all internet connectivity as wlan0 would not associate to the Access Point - if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable. However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.

• Windows not shown in Grub after installing 12.10

  - by rowanquigley

  I just installed 12.10 alongside Windows 7. I split my partition into two because disk reader during the installation didn't recognize Windows 7 as being installed on the computer. It installed correctly and I restarted only to find out it wasn't recognized in Grub also and booted straight to Ubuntu. I read this post and thought of using boot-repair would be fine but I gain this error: gpt detected. Please create bios-boot partition (>1MB, unformed filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. I've no idea what it means or what to do next. Suggestions would be appreciated and I have lost my Windows installation disk and I really don't want to have to go looking for it.

• Unable to change desktop environment in 12.10

  - by LEOXD

  I upgraded to 12.10 some days ago and now I'm unable to change between the environments. I currently have GNOME 3 (with extensions), KDE and, of course, Unity installed. The computer is a Lenovo G550. In the login screen I can get into the menu where the DEs are listed, but I can't select one. I can't use a test account of mine, which used GNOME 3, because after I logged in X crashes/restarts. Unity works, but I can't switch from the broken GNOME 3 to Unity. What did I broke during the upgrade and how can I fix it?

• Nautilus (File) 3.10.1 how to lock drag and drop bookmarks

  - by Davide Marchi

  From the new Nautilus releases exist the ability to create shortcut/bookmarks simply by drag&drop folder onto the nautilus left panel; However, this behavior can unintentionally create additional bookmarks if you are not very accurate when dragging files to bookmarks, especially by people with little experience in the use of computer. How is possible to disable the drag&drop bookmarks creation? Or ideally should be planning to implement the drag & drop mode only if you are running in conjunction with the press of a key on the keyboard ..

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

• What reference point/ tutorial could I use to help me make a "Ball rolling" game in flash?

  - by user1798964

  I am a complete newbie to programming, only took high school Computer science so I kind of know what im doing, I just want to know how I can make a ball rolling game that I want to make, could anyone show me an example of a good "ball rolling game" that has good physics and everything, I have tried to use Box2D for the physics portion of the game, but I found that using that is just code and I can't figure out how to make the graphics and details of the world I want to make in my game, all I would like to do would have a game that has the collision detection and physics of box2d only apply to one ball in it and use the left and right keys to move it. sorry if I am too unclear, if anyone could show a tutorial or something to me on how to make a proper "Ball rolling" game that has good physics that would be appreciated, thank you for taking the time to read this

• Dual monitor with different resolutions problem

  - by Mackemint

  I'm on an LG R405 with a PM965 chipset and a NVIDIA GeForce Go 8400M GS gaphics card. I'm trying to use an external monitor (Benq senseye3 G2222HDL) through a VGA out port. All was fine when installing except for the screen layouts were flip-flopped (computer defalut setup so external monitor was to the right instead of left). When I moved the secondary monitor to its real position in the setup, I started getting strange problems. I loose representation of large portions of the screen, on both screens, and have to reboot. If I plug the monitor in after rebooting I get more problems than when booting up with the monitor already plugged in, but in both cases I can barely see what I'm doing. Please advice! Regards /M

• What should I look into to find a career path?

  - by PetrakovichJ

  I am finishing up my bachelor's degree in computer science and am feeling somewhat burnt out in the field. I enjoy solving problems, programming, and using computers to find said solutions, but I feel that I never really concentrated on anything in particular and so I don't have any specialties or a path in technology to follow. I feel like a 'generic programmer' with nothing special to offer. My question is, where can I look to find this niche? I have interest in the environment, nature, sustainability, and other similar things. Is there something in these areas in particular where specialists are needed? My question is somewhat vague but where did you "find your niche"?

• In 12.04, with my Linksys WUSB54G USB adapter I can see the networks, but cannot connect to any of them

  - by tobye

  I recently loaded Ubuntu version 12.04 onto my computer, and I have a WUSB54G v4 USB wireless adapter. I first tried to get it to work by simply plugging my adapter into an open USB port. This seemed to work fine, it came up with a list of wireless adapters, so I clicked on the correct one and entered the security code. It looked like it was going to connect. It tried for about five minutes before I stopped it. I then decided to create a network as I also have one setup. I did this and it connected, only one problem, I couldn't get onto the internet. Please help me, I am new to Ubuntu and am totally lost.

• How can I disable as much "flair" as possible in Unity?

  - by UlfR

  I'm running Ubuntu 11.10 from a fresh install on a somewhat aged computer, so I have some speed problems. But since I do want to use the new cool way to work with things that Unity introduces I do not want to fiddle with getting another desktop environment. My idea is to disable as much flair as possible, but there are tonnes of options that I do not understand or have the time to read up on when I launch CompizConfig Settings Manager. Which of these could safely be disabled? Are there other places where performance could be gained by disabling things? So how can I make the whole thing a little more snappy?

• Good source for interview-style coding problems for entry/intermediate developers?

  - by soster

  I have taught myself to code over the past few years and do not have a computer science degree. As a result, I lack experience from many things, such as the basic homework/test questions many CS graduates take for granted. I recently had a tech screen interview where I fumbled and struggled to finish a (relatively) common question, I believe due to this inexperience. My question to all of you is this: do you know a good source for a bunch of these problems that includes answers, for an entry/intermediate developer who is trying to gain coding problem solving experience? The ones I've been able to find on the internet are for coding teams, so they're a bit too complicated for me. Thanks so much in advance.

• External Hard disk not workng on windows after I formatted it on Ubuntu

  - by nav_jan

  I formatted my Western Digital 500 Gb hard disk on Ubuntu 10.4 and now I want to use it on Windows 7 but it cannot detect it. I formatted it with FAT(applicable to all) option. I tried to Google this problem a bit and as suggested by one of the site i tried to format this drive with NTFS. Still windows cannot detect it. Drives in windows 7 is not a problem because I tried a different usb drive on it and it works. I can see the led of the drive glow when I connect it and I can also see remove drive safely option in lower right corner, but i cannot see any option in "my computer" to access the hard disk. I am new to Ubuntu. Any help is appreciated.
