  • how do I make my Dualshock 3 gamepad work in Ubuntu 14.04?

    - by user290527
    When my desktop computer was running Ubuntu 12.04, my PS3 controllers would work with USB. I didn't need to do any special setup. I could just plug it in before I start SuperTuxKart and it would recognize it. I can also do this on my laptop (still running 12.04). Since I gave my desktop a fresh install of Ubuntu 14.04, the controller would never work. I have played with some installed software that I found when looking for information. Here is what I get with xboxdrv: liam@Liam-CustomDesktop:~$ sudo xboxdrv --detach-kernel-driver xboxdrv 0.8.5 - http://pingus.seul.org/~grumbel/xboxdrv/ Copyright © 2008-2011 Ingo Ruhnke <[email protected]> Licensed under GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This program comes with ABSOLUTELY NO WARRANTY.

Controller: PLAYSTATION(R)3 Controller Vendor/Product: 054c:0268 USB Path: 003:012 Controller Type: Playstation 3 USB Your Xbox/Xbox360 controller should now be available as: /dev/input/js0 /dev/input/event16 Press Ctrl-c to quit, use '--silent' to suppress the event output So the existence of this controller is acknowledged at on my computer. But it never works for input. In my old installation, I didn't even need to get software like xboxdrv for it to work. I have never tried bluetooth on either computer, but I don't think I even have that on my desktop. So now, how do I make my gamepad work in Ubuntu 14.04?

  • How important is graceful degradation of JavaScript? [closed]

    - by Stephen
    Should web developers continue to spend effort progressively enhancing our web applications with JavaScript, ensuring that features gracefully degrade, thereby ensuring accessibility? Or should we spend that time focused on new features or other areas of development? The subtext of that question would be: How many of our customers/clients/users utilize our websites or applications with JavaScript disabled? Do you have any projects with requirements that specifically demand JavaScript functionality (almost all of mine do), and do those requirements also demand graceful degradation? For the sake of asking this question, I pulled up programmers.stackexchange.com without JavaScript enabled, and I was greeted with this message: "Programmers - Stack Exchange works best with JavaScript enabled". It was difficult to log in, albeit the site seemed to generally work okay. (I wasn't able to vote up any questions.) I think this is a satisfactory approach to development. Imagine the effort involved in making all of the site's features work with plain old HTML and server-side logic. On the other hand, I wonder how many users have been alienated by this approach. We've all been trained (at least the good developers among us) to use progressive enhancement and to ensure our web applications' dynamic features degrade gracefully. Is this progressive enhancement just pissing into the wind, or do some of our customers actually utilize certain web services without JavaScript enabled?

  • RTFMobile

    - by ultan o'broin
    It may seem obvious but it’s worth stating again. The idea that mobile users are going to read lots of user assistance on their devices is just wrong. So, Jakob Nielsen’s post Mobile Content Is Twice as Difficult serves as a timely reminder for anyone thinking of putting manuals as a form of user assistance onto mobile phones. There is also an excellent post on UXMag.com, explaining that one of the ways to screw up with your iPhone app is to throw an old-style user manual into the user experience: 10 Surefire Ways to Screw Up Your iPhone App.   (Image copyright and referenced from UX Magazine 2010)   Instead, user assistance  alternatives—if any at all—include one-time tours, graphics, in-context instructions, and so on. Not so sure that importing “humor” and “personality” work so well in the enterprise app space, myself. However, the message is clear: iPhone users don’t read manuals. Great message. Users will figure it out, and if they can’t, well then your app’s UX is a problem and the app will fail. Shame some teams are obsessed with figuring out ways to port existing manuals to mobile platforms without any thought for the UX. Razorfish’s Scatter/Gather blog says it all: One thing that is particularly discouraging, most material currently available on “Creating Content for the iPad” or similar themes turns out to be about getting traditional content onto, or into, the iPad. Now, manuals for non-end users in PDF format on eReaders is a different matter. I have research on that, but it’s for another post.

  • How to learn the math behind the code?

    - by Solomon Wise
    I am a 12 year old who has recently gotten into programming. (Although I know that the number of books you have read does not determine your programming competency or ability, just to paint a "map" of where I am in terms of the content I know...) I've finished the books: Python 3 For Absolute Beginners Pro Python Python Standard Library by Example Beautiful Code Agile Web Development With Rails and am about halfway into Programming Ruby. I have written many small programs (One that finds which files have been updated and deleted in a directory, one that compares multiple players' fantasy baseball value, and some text based games, and many more). Obviously, as I'm not some sort of child prodigy, I can't take a formal Computer Science course until high school. I really want to learn computer science to increase my knowledge about the code, and the how the code runs. I've really become interested in the math part after reading the source code for Python's random module. Is there a place where I can learn CS, or programming math online for free, at a level that would be at least partially understandable to a person my age?

  • samba share not on network after upgrading to Ubuntu 12.04LTS.

    - by Sylvain Huard
    I just upgraded an old Ubuntu box to 12.04LTS (machine named A-Ubuntu). This is an upgrade not a format re-install. All the accounts and config were preserved. The basic setup is a local network with 2 Ubuntu machines (let say A-Ubuntu, B-Ubuntu) and a MAC (C-MAC). Before the upgrade, all of them could see each other by their names not only the IP address. The local network has a D-Link Router where everybody is connected with RJ-45 wired etherenet (not wi-fi). Since the A-Ubuntu upgrade, we can't see this machine name on the Network and its name is not on machine list in the D-Link router anymore. We can see it's IP address only. I can't access A-Ubuntu from the other two by its name but I can ping it with its address (192.168.0.109). From A-Ubuntu, I can connect and see the shared samba folders on B-Ubuntu and C-MAC. But from B-Ubuntu and C-MAc, I can't connect to A-Ubuntu. Correct me if I'm wrong but this tells me that Samba should be fine and the real problem is that A-Ubuntu does not advertise its name on the Network so the D-Link does not have it in its table so nobody else finds it. After a lot of googling, I see that it is the job of avahi and mdns to do so. Those packages are running, I checked multiple config files for samba, avahi, mdns to see as if it is like the examples on the WEB and also similar to what I find on the working B-Ubuntu machine. This is the same. I did multiple service restart with samba, avahi, remove the firewall to make sure it does not block the hostname broadcast. I rebooted multiple time to make sure the update I was making were effective. Still, Can't see the A-Ubuntu name on the network. Any idea what it can be?, Where to look next?

  • How do I access shared folders on Ubuntu server from Mac OS?

    - by Stephen
    I have an old dell desktop running ubuntu 11.04, I also have samba installed on it. I'm trying to access the shared folders on the Ubuntu machine from my Mac, so I go into 'Finder', click on 'Go' and 'Connect to Server'. I type in the ip address of the ubuntu machine smb://xxx.xxx.x.xx and click connect, I can then see the list of shared folders from the ubuntu machine so I know its making a connection. But when I access the 'Music' folder I get an error message stating: There was an error connecting to the server "xxx.xxx.x.xx". Check the server name or IP address, and try again. Any thoughts anyone ? EDIT I have a external hard drive attached to the server, and the folders I'm trying to access are located on that external hard drive. The location of the folder is /media/HD-CELU2/test, so I think the path from Finder should be smb://xxx.xxx.x.xx/media/HD-CELU2/test, but having tested this, I'm still not getting in. P.S. I'm using Samba as I have a Windows machine on my home network as well.

  • How to fetch only the sprites in the player's range of motion for collision testing? (2D, axis aligned sprites)

    - by Twodordan
    I am working on a 2D sprite game for educational purposes. (In case you want to know, it uses WebGl and Javascript) I've implemented movement using the Euler method (and delta time) to keep things simple. Now I'm trying to tackle collisions. The way I wrote things, my game only has rectangular sprites (axis aligned, never rotated) of various/variable sizes. So I need to figure out what I hit and which side of the target sprite I hit (and I'm probably going to use these intersection tests). The old fashioned method seems to be to use tile based grids, to target only a few tiles at a time, but that sounds silly and impractical for my game. (Splitting the whole level into blocks, having each sprite's bounding box fit multiple blocks I might abide. But if the sprites change size and move around, you have to keep changing which tiles they belong to, every frame, it doesn't sound right.) In Flash you can test collision under one point, but it's not efficient to iterate through all the elements on stage each frame. (hence why people use the tile method). Bottom line is, I'm trying to figure out how to test only the elements within the player's range of motion. (I know how to get the range of motion, I have a good idea of how to write a collisionCheck(playerSprite, targetSprite) function. But how do I know which sprites are currently in the player's vicinity to fetch only them?) Please discuss. Cheers!

  • installing ubuntu on SSD

    - by kunal
    Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

  • Can't enable wireless lan on Fujitsu Siemens A1665G with Ubuntu 11.10 installed

    - by Theo
    I saw my old Notebook yesterday and wanted to make that work again. On Windows XP the wireless worked still fine. Then I installed new Ubuntu 11.10 32bit and I'm sadly not able to make the wireless enabled. [I replaced Win XP entirely] lspci lists following network: 08:0a.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) So after recommendation from this link I installed the b43 firmware module. iwconfig prints the following: wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associatd Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management: off As you can see, my wireless lan adapter is not turned on. sudo iwconfig wlan0 txpower auto Doesn't change anything. Then I tried to make it work with rfkill. rfkill list 0: phy0: Wirless LAN Soft blocked: no Hard blocked: yes sudo rfkill unblock all rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes remains the same. The question is now, how I could enable the hard blocked wireless LAN. There is no hardware switch for wlan integrated. However there is a button to change the state. I always thought this would be software sided, but it seems to make some hardware changes as well... The wireless LED is also not blinking (as it did on windows xp) I reset bios and searched for some settings in there, but it has only a few options and nothing to do with wireless settings, nothing works here.. At last I tried to install the acer hotkeys but I was not able to manage that. I installed the acerhkgui package, but in initializing progress, it was not able to compile acer hotkeys for my machine. There was a message that asm/linkage.h was not found while compiling. Do you have any ideas what I could do to make this hard blocked stuff disabled and my wireless card work? PS: I also tried sudo rm /dev/rfkill and a reboot to reinit that stuff... No success :(

  • Should I go with OpenGL to see my future in Game Development industry? [closed]

    - by Priyank
    Possible Duplicate: Should I continue studying OpenGL or just switch to DirectX to give me a better chance of landing a job in the game industry? I tried Google but found quite old articles, so I am in search of an answer in context to year 2012. Hi all, I don't know if you will consider this question appropriate for this community but I am constantly searching for a perfect answer. What I have seen is that most of the games that are released these days are DirectX 1x based. Except for few games like Starcraft or Diablo which don't have high end graphics are using OpenGL. So I have few questions to ask. The platforms i would like to target are PC (windows), Xbox 360 and PS3 (must). Should I go with learning OpenGL to see my future in game development industry? Or should I shift to Directx? If I learn OpenGL first, will it be difficult to learn direcx then? Which API is most suitable for indie development? Which one of the two API's are better from coder's (programmer's) point of view? Like OOP and style of coding. Is openGL being cross platform should be the only reason to choose it over Directx? Even when vendors are not providing enough stable drivers for it. Thanks in advance. I have read this post, but I have few questions. Should I continue studying OpenGL or just switch to DirectX to give me a better chance of landing a job in the game industry?

  • Google Blogger Website CName and/or Text File Issues

    - by Francis Gibbons
    I have a blogger Blog website and I would like to have it show up on my company website. I have read a couple articles out there on how to do it. A hand full of them talk about using FTP which is old and no longer available. However, I am trying to following along with this one: http://www.infinite42.com/small-business/integrate-blogger-blog-website Which seems pretty easy but I am having a problem getting Google to Verify the DNS CName or Text Record that I created on my Windows 2007 Server. Do I need to create this record at the registra level. Right now the domain is setup at the registra to point the www record to my server where on my server I tried the Txt Record and the CName Record with no luck in DNS. Here are the Google instructions for creating a CName file record in DNS: Follow the steps below to create a DNS (Domain Name System) record that proves to Google that you own the domain. Add the CNAME record below to the DNS configuration for abc.com. CNAME Label / Host: CNAME Destination / Target: Click Verify below. When Google finds this DNS record, we'll make you a verified owner of the domain. (Note: DNS changes may take some time. If we don't find the record immediately, we'll check for it periodically.) To stay verified, don't remove the DNS record, even after verification succeeds. Here is the link to do it with a CName: http://googlewebmastercentral.blogspot.com/2012/08/domain-verification-using-cname-records.html When I go to add my CName record on my server's DNS the only two fields available are Alias Name and Fully Qualified Domain Name. How am I suppose to create this record can someone please tell me? Thanks, Frank

  • Expiry time in notify-send notifications

    - by gsingh2011
    On my HP computer running Ubuntu 12.04, the brightness and volume increments were much higher than I wanted. On top of that, the notification for the volume was just plain wrong (0% sound did not correspond to 0 on the progress bar). So I decided to override these options with my own commands. I used CompizConfig Settings Manager to add custom commands to the brightness and volume keys (this couldn't be done in the regular settings because these keys were handled by the BIOS, unlike normal function keys). I used xbacklight to control the brightness and amixer to control the volume. The problem is that the nice notify-send notifications don't show up when I manually set the brightness/volume, so now I have to do that myself too. However, there are two problems with notify-send: The expire time option doesn't work You have to wait until a notification is finished before the next one comes up Before I overrided the brightness/volume keys, the system was able to send notifications without these two restrictions. Notifications disappeared within 3 seconds (instead of the default 10), and if I double tapped the volume or brightness button, the progress bar would immediately change to the new brightness (instead of showing the old progress bar for 10 seconds and then showing the new one). Since the system was able to do it, I was wondering how I can achieve the same type of notifications?

  • Ubuntu 12.04 MySQL 5.5 MyODBC 5.1 or 3.1 query hangs

    - by jorgearr
    I have been able to install Ubuntu 12.04 with LAMP MySQL version 5.5.x It works fine within linux, it allows me to connect from myodbc windows vista or windows 7 I have configured networking access and have been able to access from windows vista using putty and other tcp connections like mysql query browser. I have also configured or disabled ufw firewall and apparmor. The connection works fine until I query data from the tables. It lets me query small amounts of data like: SELECT name FROM users limit 20 but if I do a SELECT * FROM users, it goes on a never-ending loop. This happens even on tables with very few records like 5 or even less. The problems occur with windows because I tried ssh from linux mint and it worked fine. I need to be able to work using MyODBC either 3.51 or 5.1 since my client program is made in VB6 and connects to mysql server via tcp/ip. The server is an HP PROLIANT ML350G6 with Intel Xeon 64 bits. I tried several ubuntu server version (12.04 64bit, 10.10 64bit, 11.04 32bit) and none has worked I even tried CentOS 6.3 and the same. As a reference, it works fine with onother ubuntu server version 6.x on HP Proliant 150 and mysql 5.0.x that is like 7 years old and never updated. Help Please.

  • Whats the greatest most impressive programing feat you ever witnessed? [closed]

    - by David Reis
    Everyone knows of the old adage that the best programmers can be orders of magnitude better than the average. I've personally seen good code and programmers, but never something so absurd. So the questions is, what is the most impressive feat of programming you ever witnessed or heard of? You can define impressive by: The scope of the task at hand e.g. John single handedly developed the framework for his company, a work comparable in scope to what the other 200 employed were doing combined. Speed e.g. Stu programmed an entire real time multi-tasking app OS on an weekened including its own C compiler and shell command line tools Complexity e.g. Jane rearchitected our entire 10 millon LOC app to work in a cluster of servers. And she did it in an afternoon. Quality e.g. Charles's code had a rate of defects per LOC 100 times lesser than the company average. Furthermore he code was clean and understandable by all. Obviously, the more of these characteristics combined, and the more extreme each of them, the more impressive is the feat. So, let me have it. What's the most absurd feat you can recount? Please provide as much detail as possible and try to avoid urban legends or exaggerations. Post only what you can actually vouch for. Bonus questions: Was the herculean task a one-of, or did the individual regularly amazed people? How do you explain such impressive performance? How was the programmer recognized for such awesome work?

  • E3 Booth Babes Display a Painful Lack of Video Game Knowledge [Video]

    - by Jason Fitzpatrick
    If you thought a prerequisite for manning a booth at an electronics expo was a passing knowledge of the electronics and games you were promoting, you were wrong. In the above video Chloe Dykstra puts a set of “booth babes” from the E3 2011 conference to the test by asking them simple questions about video games both new and old. If you’re a gaming fan and you can watch this video without laughing out loud you’ve got an iron will (or you’re shaking your head in disbelief that someone could work a gaming convention and not know the answers to these questions). We won’t lie, we were shaking our head when the one model admitted that she’d worked at GameStop for a year and still didn’t know any of the answers. What questions would you put on list?

  • HDMI video output not working for external monitor

    - by user291852
    I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.

  • 2D platformers: why make the physics dependent on the framerate?

    - by Archagon
    "Super Meat Boy" is a difficult platformer that recently came out for PC, requiring exceptional control and pixel-perfect jumping. The physics code in the game is dependent on the framerate, which is locked to 60fps; this means that if your computer can't run the game at full speed, the physics will go insane, causing (among other things) your character to run slower and fall through the ground. Furthermore, if vsync is off, the game runs extremely fast. Could those experienced with 2D game programming help explain why the game was coded this way? Wouldn't a physics loop running at a constant rate be a better solution? (Actually, I think a physics loop is used for parts of the game, since some of the entities continue to move normally regardless of the framerate. Your character, on the other hand, runs exactly [fps/60] as fast.) What bothers me about this implementation is the loss of abstraction between the game engine and the graphics rendering, which depends on system-specific things like the monitor, graphics card, and CPU. If, for whatever reason, your computer can't handle vsync, or can't run the game at exactly 60fps, it'll break spectacularly. Why should the rendering step in any way influence the physics calculations? (Most games nowadays would either slow down the game or skip frames.) On the other hand, I understand that old-school platformers on the NES and SNES depended on a fixed framerate for much of their control and physics. Why is this, and would it be possible to create a patformer in that vein without having the framerate dependency? Is there necessarily a loss of precision if you separate the graphics rendering from the rest of the engine? Thank you, and sorry if the question was confusing.

  • Similar domains using my business' content, and stealing SEO results

    - by Murciano
    I've been hired to create a website for a restaurant in my city, let's call it "Flying Dragon" Chinese restaurant. The restaurant has never had a website, though the business itself is about ten years old. However, if you Google the restaurant's name, the first site that comes up seems to be affiliated with the restaurant itself, even though it is not. This site - let's say, flyingdragonchinese.com - is also the one that Google has apparently selected, in its results, to be the official website of the restaurant - in essence, the first Google result is flyingdragonchinese.com, and directly beneath it, within the same entry, are the Google reviews and contact information. Upon visiting flyingdragonchinese.com (again, not the actual name), I see that the website has taken the menu content from the restaurant, in the same manner that Yelp does, but it also seems (to the untrained eye) to be the restaurant's official site. Basically, someone has created a fake website for the business (I am not sure why) using its actual menu and contact information, and is hogging the search results. The concept is similar to a "scraping site" except that the information seems to have been stolen manually. The main problem is that visitors to this site will have an inaccurate impression of the restaurant. I feel like the obvious solution is to register a new domain for my site, and simply beat out this competitor (or whatever it is) with smarter SEO and business verification with Google. However, the Conan-the-Barbarian-web-designer part of me wants to somehow bash this other site (deservedly?) into oblivion. But I don't know what I can really do, besides maybe issuing a cease-and-desist letter, or trying to contact the web host for the site, although there is no contact information available on this "fake" site for the site owner. Has anyone ever experienced something like this? Is there any solution?

  • SQL SERVER – SELECT INTO with FileGroup or Partitionis Not Possible

    - by Pinal Dave
    The other day, I received an email from user and after a long time before I answer the question, I had to check the answer online. Here is the question - I want to create a new table based from old table, but when I execute following script it gives me an error. Is there anything I am missing in my syntax? SELECT *  INTO NewTableName ON MyFileGroup FROM MyOldTableName I faintly remember that this was not possible in earlier version of SQL Server but I was not sure if this feature was added in the recent versions or not. I quickly tried few syntaxes and referred online documentation and learned that it is still not possible in the latest version of SQL Server. The alternative is to just go ahead and change the default filegroup of any new table with following script. Though, I do not like change the default filegroup for new tables. It is possible that when I have changed the default filegroup some other code executes behind the scene by automated system or my colleague, it will be also created on new filegroup. ALTER DATABASE DatabaseName MODIFY FILEGROUP NameofFileGroup DEFAULT The reason this feature is not supported is that SELCT INTO is minimally logged operation. I seriously hope that some day in the future this feature get added in.

  • Virtualbox shared folder mount from fstab fails; works once bootup is complete

    - by Ben
    I've got Ubuntu 13.10 installed in Virtualbox 4.3. The host machine is Windows. I have a couple of Virtualbox shared folders being mounted by /etc/fstab. Until recently this setup worked just fine, but after upgrading from Ubuntu 13.04 and Virtualbox 4.2 (at essentially the same time) the fstab mounting stopped working. I get the following error during boot: An error occurred while mounting /home/benme/Documents. keys:Press S to skip mounting or M for manual recovery Pressing M for manual recovery and then trying to mount manually also fails: root@benme-vb:~# cd /home/benme root@benme-vb:/home/benme# mount Documents /sbin/mount.vboxsf: mounting failed with the error: No such device But if I instead skip mounting during boot, wait for Unity to start and then mount manually in a shell, everything works fine: benme-vb ~ % ls Documents benme-vb ~ % sudo mount Documents [sudo] password for benme: benme-vb ~ % ls Documents # actual file list omitted Note that when I mount manually I'm letting mount take all the options from /etc/fstab, and it works. This suggests to me that it's some sort of timing issue, where Virtualbox isn't "ready" to provide the shared file mounts at the point /etc/fstab mounts are run during bootup. Here's the fstab line, just for completeness: Documents /home/benme/Documents vboxsf uid=benme,gid=benme,dmode=774,fmode=664 0 0 Is there something I can do about this from the Ubuntu side? Or does anyone happen to know more about this from the Virtualbox angle? I've found an old report on the Virtualbox bug-tracker with identical symptoms, but in that case the user had updated Virtualbox without updating their guest additions and resolving that fixed the problem; this isn't happening here, I've definitely got the 4.3 guest additions installed.

  • How can I install Celtx 2.9.7 properly on Ubuntu 12.04 LTS?

    - by cruxfilm
    I am new to Ubuntu and Linux and I want to install and use the newest version of the screenwriting software Celtx on Ubuntu 12.04 LTS. After trying https://answers.launchpad.net/ubuntu/+source/ubiquity/+question/206295 and using sudo add-apt-repository ppa:dreamstudio/video sudo apt-get update sudo apt-get install celtx I unfortunately had to find out that was a rather old version with a fairly screwed up UI. I then downloaded the newest version from http://download.celtx.com/2.9.7/Celtx-2.9.7-64.tar.bz2 but now I don't know how to properly install it. I extracted it to /home/username/ (there was no ~/bin/) as described here and I can now launch the application by running the file celtx within that folder (I get asked whether I want to Display, run or run it in Terminal) and it works fine. But I can't get it to launch from Unity. I tried right-clicking the launcher button and going "Lock to Launcher" while it's running and it does create an icon but clicking it to launch the program does nothing. Also searching for celtx in the Dash doesn't find the app. And advice on how to properly install Celtx 2.9.7 in Ubuntu 12.04 LTS?

  • Unavailable packages repository

    - by bitmask
    I'm running ubuntu 11.10 (oneiric) on this machine, and suddenly, apt is unable to update properly. If I ask it to update its package information, by running apt-get update (or alternatively telling the update manager to "check"), it succeeds for about 120 packages (more precisely, I get about 120 Ign/Hit notes) and then says it cannot find universe Sources and restricted amd64: Hit http://de.archive.ubuntu.com oneiric-backports/multiverse Translation-en Hit http://de.archive.ubuntu.com oneiric-backports/restricted Translation-en Hit http://de.archive.ubuntu.com oneiric-backports/universe Translation-en Err http://de.archive.ubuntu.com oneiric/universe Sources 404 Not Found [IP: 141.30.13.20 80] Err http://de.archive.ubuntu.com oneiric/restricted amd64 Packages 404 Not Found [IP: 141.30.13.20 80] W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/oneiric/universe/source/Sources 404 Not Found [IP: 141.30.13.20 80] W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/oneiric/restricted/binary-amd64/Packages 404 Not Found [IP: 141.30.13.20 80] E: Some index files failed to download. They have been ignored, or old ones used instead. I manually checked the de server and cannot find anything wrong with the stuff it's complaining about. Also it looks pretty much like, say, the us mirror. But oddly enough, the IP it lists, seems to point to a debian package server, which obviously does not contain ubuntu packages. So, is this a local problem that I can fix somehow (and if so, how?) or is there actually some server down right now?

  • Updating Ubuntu server from 8.10 to 10.04

    - by Ward
    I have a VPS that has Ubuntu 8.10 Server Edition installed on it and I would like to upgrade it to 10.04. What would be the correct way of doing this? I only have ssh access to it and a "Start/Shutdown VPS" in the client panel of the vendor. In other words, I do not have physical access to it. Also worth noting is that I apparently cannot install programs any more since the sources (osuosl.org ?) are not online. Not the ones this server has set anyway. # apt-get update Ign http://ubuntu.osuosl.org intrepid Release.gpg Ign http://ubuntu.osuosl.org intrepid/main Translation-en_US Ign http://ubuntu.osuosl.org intrepid/universe Translation-en_US Ign http://ubuntu.osuosl.org intrepid Release Ign http://ubuntu.osuosl.org intrepid/main Packages Ign http://ubuntu.osuosl.org intrepid/universe Packages Err http://ubuntu.osuosl.org intrepid/main Packages 404 Not Found Err http://ubuntu.osuosl.org intrepid/universe Packages 404 Not Found W: Failed to fetch http://ubuntu.osuosl.org/ubuntu/dists/intrepid/main/binary-amd64/Packages.gz 404 Not Found W: Failed to fetch http://ubuntu.osuosl.org/ubuntu/dists/intrepid/universe/binary-amd64/Packages.gz 404 Not Found E: Some index files failed to download, they have been ignored, or old ones used instead.
