• Does UX matter for enterprise software?

  - by Ryan

  I've come to notice that a lot of software that companies use for managing things like time, expenses, setting up phone systems, etc is very non-intuitive from a user experience point of view. I know personally I waste a lot of time just trying to figure out how to navigate these systems, especially if I don't have a co-worker close by who I can bug to help me out. The help files are usually just as bad as the user interface itself. Are companies that complacent or are there just not any comparable enterprise products out there which do the job for these sorts of tasks? It seems that on the consumer side there is plenty of market opportunity for creating better user experiences, but how about for enterprise software? Obviously a certain level of slickness is not going to matter to a company, but when a better UX design translates to time saved, it's hard to argue against that. Edit: I'm not referring to in-house applications, but rather off the shelf systems from large software companies.

• Chambers In A Castle Algorithm

  - by 7Aces

  Problem Statement - Given a NxM grid of 1s & 0s (1s mark walls, while 0s indicate empty chambers), the task is to identify the number of chambers & the size of the largest. And just to whet my curiosity, to find in which chamber, a cell belongs. It seems like an ad hoc problem, since the regular algorithms just don't fit in. I just can't get the logic for writing an algorithm for the problem. If you get it, pseudo-code would be of great help! Note - I have tried the regular grid search algorithms, but they don't suffice the problem requirements. Source - INOI Q Paper 2003

• Difference left/right super button

  - by Erik Keemink

  When I press my left super key the gnome shell appears and when I press the right super key it does not. Moreover pressing right super + T does open a terminal at once, but when using left super I have to press the t twice, when I press the t only once it is similar to just pressing the t without holding super left. This last point also occurs with other shortcuts that I defined (like super+L, super+E), but not with super+up/down/left/right. What I want is to press either super key to get the gnome shell and to use either super key in combination with T to open a terminal immediately (and similar with other shortcuts). I use Ubuntu 12.04 LTS and the gnome 3 shell.

• 12.10 lost window maximize and minimize options, utility bar and launcher lost too

  - by user12448

  I recently installed Ubuntu 12.10 on my Dell Inspiron 7520. Everything is good except the hyperactive fans.The graphic cards are Intel and AMD Radeon 7730. I am trying to get away with the fan problem butI don't really know the terminal hence I am just trying to use the commands available on the forums.But this time I don't know what did I do that now I don't have the utility bar, launch bar and the basic features like the window minimize and maximize don't work. I have this impression I may have uninstalled some drivers . But still not sure what to do. Feel a need of dire help!

• Make sudoers work with only certain parameter?

  - by Evan

  I'm trying to make my sudoers file allow a user to adjust the backlight without having to enter in the password. This is what I have: # User alias specification Cmnd_Alias ADJBL = /usr/bin/su -c "echo 150 >/sys/class/backlight/intel_backlight/brightness" # For our user.. ouruser HOME=(root) NOPASSWD:ADJBL .. but it doesn't seem to be working, I still get prompted for the password when I try and run that command with sudo. Apparently there is something I'm missing here, any ideas?

• How do I add a network printer in Ubuntu 12.04?

  - by Ricky Robinson

  I know the name and the IP address of a network printer, but I can't seem to be able to search by IP address or name. Ubuntu developers love to move things around to make it difficult for users, so now with Ubuntu 12.04 I can only go on Application -> System Tools -> System Settings -> Printers, click on Network and a list of printers appears. Too bad the one I want to add isn't there. How do I do it? Here it suggests System -> Administration -> Printing, which simply doesn't exist.

• Increase launcher and applet spacing on the Gnome Classic panel

  - by whtyger

  I'm using Ubuntu 12.04.1 with Gnome Classic. I added some launchers on the top panel, but they are placed too tightly (also take a look at separators, they aren't really separate anything): My Gnome Panel image Can I increase the spacing between the launchers? AFAIK this can be done by the editing of ~/.config/gtk-3.0/gtk.css. I've managed to toggle bold font setting for the panel this way. But I haven't found which parameter have an influence on the launcher and applet spacing. Also the size of icons seems too big for me - they occupy all place from the top to the bottom of the panel, without any border. They were smaller when I was using 10.04. Is there any way to reduce their size also?

• After installing Ubuntu I can't boot Windows 8 anymore

  - by Gian Luca Scoccia

  I just bought a new laptop (a lenovo ideapad Z500) and it came installed with Windows 8. I wanted to have Ubuntu on it too, therefore I resized the Win8 partition from the control panel and installed Ubuntu on the free space I created. Ubuntu works perfectly, Windows does not load anymore... I tried the recommended repair with Boot-Repair but it did not fix, now I get a "Windows boot loader failed to start" on startup and then I get the GRUB screen. The partition summery created by Boot-Repair is here: http://paste.ubuntu.com/1444837/. How can I fix this? Thanks in advance for your help.

• does eCryptfs support multiple users?

  - by new to eCryptfs

  I'm new to ecryptfs and I need some clarification on how it works. Suppose there are two root users userA and userB, If I mount some folder under userA: [userA@Dev] $ mount ecryptfs real img now I can visit the img folder to access decrypted data. My questions is: While userA is still in log in state. Can userB login and access the decrypted data? This is currently what I observed on my local machine, but I'm not sure if it was cause by my misconfiguration. If it is the case, how can I avoid other users from accessing the decrypted data while userA is in login state?

• /dev/sda2 contains a filesystem with error after partitioning

  - by Private

  I just wanted to create a separate home partition on my Ubuntu 12.10 system. I booted the liveDVD, resized the sda2 partition (28gb of data resized to 30gb based on MiB [originally on a 100gb partition]) and made a new ext4 partition for the home folder. The drive is an SSD drive. I had changed the settings (noatime etc.) for SSD succesfully a week ago. On reboot I get the following error: /dev/sda2 contains a filesystem with errors Inode 74669 has an invalid extent node (blk 6881289) fsd / [953] terminated with status 4 What would you suggest me to do? If I can avoid a clean install that would save me a lot of time (I had just done all the config). I was following this HOWTO, but I did not get to changing any of the files or configs other than those with gparted. I have a (two-week old) SSD Samsung drive which is functioning just fine (other specs see bottom of this question). Other specs: 64bit 12.10, i7, 8gb ram, nvidia.

• Internet key not always detected by the operating system

  - by Carlo Gisonni

  I've over the time, tried and installed several versions of Ubuntu. Those versions I like more than others are: Lubuntu and Kubuntu. Everything seems to work properly but the Internet key. I do not know if it may depends on the weather, the moonphase or the tides but the Internet key is not always detected by the system and is sometimes very difficult to establish a connection when I do need to connect to internet. Without applyng any change sometimes works sometimes not. I've so far not found the solution and I think is a quite strange behaviour of the operating system as if the settings are wrong, should never work Awaiting a kind answer from those of you willing to help.

• Restore default keyboard shortcut for Workspace Switcher/Show Desktop

  - by To Do

  I tried setting the default keyboard shortcut to Hide normal windows (Show desktop) to Super + S. It didn't work and now whenever I press Super + S, I get the workspace switcher. I tried setting Hide normal windows back to Ctrl + Super + S, but it doesn't work. I'm still getting the Workspace switcher. How can I reset these two settings? I use the Show Desktop quite a lot and it is quite annoying not being able to do it.

• How do I get a Vodafone K3772-Z USB modem working?

  - by Ian

  I recently switched from Win 7 to Ubuntu 12.04...Best day of my life :) I have a question relating to my Vodafone K3772-Z USB modem. When I plug it in, the lights start flashing on the device, meaning that it is functional. In the network menu I get a "Wired network Vodafone K3772-Z disconnected". I have set up the a connection by using Edit connections - mobile broadband - Add, but in the add window the "Create a connection for this mobile device" is blanked out and says "Any Device". Does anyone perhaps have an idea of what I could do to get it working?

• Google Analytics Goal tracking external referrals

  - by user1561108

  I have goal tracking setup on my site for a target url. It works insofar as it tracks all pageviews on my site leading up the goal. But it doesn't appear to be tracking the external referrer that the user came from initially, marking it as (entrance) and the step before that (not set). Is this standard behaviour for goals not to record external referrer and how can I add referrer tracking to my goal?

• Amazon Affiliate search using a movie title

  - by Matt Walker

  I am currently working on a movie trailer site. I have over 300 movies and I do not want to add an amazon affiliate link to each one individually. Does amazon offer any sort of api that will allow me to use a movie title to search for a dvd on amazon? Ex. For the movie skyfall, the amazon affiliate link would be amazon.com/search/dvd/skyfall/affiliateid ^ I just made the link up as i don't know how their system works, but I just want it to do a search on the movie title Thanks in advance for any help you can give me!

• XCart Skip Checkout Steps

  - by user900553

  I am using xcart. In the checkout process, skip the step that appears after a customer clicks the add to cart button on the product page. It takes them to a page that shows the product and the text Added to your shopping cart. I want to take them directly to the view cart page, right before the checkout page. I also tried: Enable Redirect customer to cart after adding a product option in X-Cart admin back-end -Settings - General settings. Still not working. Anybody have Idea about this?

• Optimal sprite size for rotations

  - by Panda Pajama

  I am making a sprite based game, and I have a bunch of images that I get in a ridiculously large resolution and I scale them to the desired sprite size (for example 64x64 pixels) before converting them to a game resource, so when draw my sprite inside the game, I don't have to scale it. However, if I rotate this small sprite inside the game (engine agnostically), some destination pixels will get interpolated, and the sprite will look smudged. This is of course dependent on the rotation angle as well as the interpolation algorithm, but regardless, there is not enough data to correctly sample a specific destination pixel. So there are two solutions I can think of. The first is to use the original huge image, rotate it to the desired angles, and then downscale all the reaulting variations, and put them in an atlas, which has the advantage of being quite simple to implement, but naively consumes twice as much sprite space for each rotation (each rotation must be inscribed in a circle whose diameter is the diagonal of the original sprite's rectangle, whose area is twice of that original rectangle, supposing square sprites). It also has the disadvantage of only having a predefined set of rotations available, which may be okay or not depending on the game. So the other choice would be to store a larger image, and rotate and downscale while rendering, which leads to my question. What is the optimal size for this sprite? Optimal meaning that a larger image will have no effect in the resulting image. This is definitely dependent on the image size, the amount of desired rotations without data loss down to 1/256, which is the minimum representable color difference. I am looking for a theoretical general answer to this problem, because trying a bunch of sizes may be okay, but is far from optimal.

• ConsumeStructuredBuffer, what am I doing wrong?

  - by John

  I'm trying to implement the 3rd exercise in chapter 12 of Introduction to 3D Game Programming with DirectX 11, that is: Implement a Compute Shader to calculate the length of 64 vectors. Previous exercises ask you to do the same with typed buffers and regular structured buffers and I had no problems with them. For what I've read, [Consume|Append]StructuredBuffers are bound to the pipeline using UnorderedAccessViews (as long as they use the D3D11_BUFFER_UAV_FLAG_APPEND, and the buffers have both D3D11_BIND_SHADER_RESOURCE and D3D11_BIND_UNORDERED_ACCESS bind flags). Problem is: my AppendStructuredBuffer works, since I can append data to it and retrieve it from the application to write to a results file, but the ConsumeStructuredBuffer always returns zeroed data. Data is in the buffer, since if I change the UAV to a ShaderResourceView and to a StructuredBuffer in the HLSL side it works. I don't know what I am missing: Should I initialize the ConsumeStructuredBuffer on the GPU, or can I do it when I create the buffer (as I amb currently doing). Is it OK to bind the buffer with a UAV as described above? Do I need to bind it as a ShaderResourceView somehow? Maybe I am missing some step? This is the declaration of buffers in the Compute Shader: struct Data { float3 v; }; struct Result { float l; }; ConsumeStructuredBuffer<Data> gInput; AppendStructuredBuffer<Result> gOutput; And here the creation of the buffer and UAV for input data: D3D11_BUFFER_DESC inputDesc; inputDesc.Usage = D3D11_USAGE_DEFAULT; inputDesc.ByteWidth = sizeof(Data) * mNumElements; inputDesc.BindFlags = D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_UNORDERED_ACCESS; inputDesc.CPUAccessFlags = 0; inputDesc.StructureByteStride = sizeof(Data); inputDesc.MiscFlags = D3D11_RESOURCE_MISC_BUFFER_STRUCTURED; D3D11_SUBRESOURCE_DATA vinitData; vinitData.pSysMem = &data[0]; HR(md3dDevice->CreateBuffer(&inputDesc, &vinitData, &mInputBuffer)); D3D11_UNORDERED_ACCESS_VIEW_DESC uavDesc; uavDesc.Format = DXGI_FORMAT_UNKNOWN; uavDesc.ViewDimension = D3D11_UAV_DIMENSION_BUFFER; uavDesc.Buffer.FirstElement = 0; uavDesc.Buffer.Flags = D3D11_BUFFER_UAV_FLAG_APPEND; uavDesc.Buffer.NumElements = mNumElements; md3dDevice->CreateUnorderedAccessView(mInputBuffer, &uavDesc, &mInputUAV); Initial data is an array of Data structs, which contain a XMFLOAT3 with random data. I bind the UAV to the shader using the Effects framework: ID3DX11EffectUnorderedAccessViewVariable* Input = mFX->GetVariableByName("gInput")->AsUnorderedAccessView(); Input->SetUnorderedAccessView(uav); // uav is mInputUAV Any ideas? Thank you.

• Blending transition in cocos2d

  - by fiddler

  In my cocos2d-iphone game, I have 2 backgrounds (CCnodes), each containing a quite complex hierarchy of sprites. I would like to make a smooth transition between them: initially, only the first background is visible at the end, only the second one is visible Is there a good way to set the opacity of a full hierarchy of sprites ? I tried to recursively set the opacity of all the contained sprites. It kinda works except that: i guess it's not very efficient i would like the opacity of overlapping sprites to be 'merged' (as if the background was one single big sprite)

• Collisions on complex map 2D

  - by waxx

  I'm currently thinking about collision and map system that I want to use in my next game and I'm kind of puzzled. Maps are going to be somewhat complex with lots of irregularities and thus tiling is out of question. I thought about an editor where you'd draw rectangles on the map that would represent areas that are collidable with and then saving such "collision map" with only black/white gfx. Or maybe should I save exact rectangles data with their x/y/width/height into some text file and go from there? What would you recommend? Thanks.
