  • Why does LightDM only show a custom wallpaper on the login screen if I have selected one of the default wallpapers?

    - by Mauricio
    LightDM only changes wallpapers if I have selected one of the default wallpapers. If I choose another image from my pictures, LightDM shows the default wallpaper. Why is this happening, and how can I make LightDM show my wallpaper if it is not one of the defaults? As @doug said in his answer, it works if you click on the little + symbol in the appearance settings: after you do that, LightDM changes wallpapers.

  • Include all php files in one file and include that file in every page if we're using hiphop?

    - by Hasan Khan
    I understand that in normal php if we're including a file we're merging the source of it in the script and it would take longer for that page to be parsed/processed but if we're using HipHop shouldn't it be ok to just create one single php file and include every file in it (that contains some class) and every page which needs those classes (in separate file each) can just include one single php file? Would this be ok in presence of HipHop?

  • is good for one year experince Java Developer to do VB.NET development?

    - by tanghao
    I'm a java programmer with around one and half years experience. Recently my boss wants me to develop an excel add-in with VB.NET in next a few months or maybe I have to be fully in charge of this add-in in the further. It makes me quite nervous right now because I am really not sure what this VB.NET development experience could mean to me in the further as I am not so sure if it's good to diverse my experience in current stage. Any one could give some helps and suggestions?

  • Which is faster, copying everything at once or one thing at a time?

    - by fredley
    I am transferring a bunch (20+) of large (1GB+) files to my external flash drive over USB 2.0. Is it quicker to just sling them all over at once (as in one at a time but not waiting for the previous transfer to finish) so that there are multiple transfers going on, or transfer one, wait for it to finish, transfer the next. The files are coming from a variety of locations so I can't do one single big transfer. Are there any other advantages to one way or the other that are worth considering?

  • Bluetooth adapter turned from working fine to unrecognized

    - by easoncxz
    i had been using bluetooth fine, with devices working, but today when i turned on my computer again bluetooth strangely failed. there is a bluetooth icon on the top bar, showing "bluetooth on", but if i click on the "bluetooth settings" item, a system settings window shows up and shows me a bluetooth on-off switch which is disabled (i.e. fixed to off). more information about my case: i am a new linux used, coming from windows, and do not know supposedly-obvious commands. i am using a laptop. it initially doesn't have bluetooth. i bought a built-in type (instead of USB type) bluetooth module, and added it inside the laptop. hence, i do not have a specific FN+* key for bluetooth. in windows, i needed to install an additional driver that was intended for other machines in my laptop's seires which have built-in (i.e. factoryly built-in)j bluetooth modules. the Fn+* key seemed to only affect wifi under ubuntu. i have been successfully using magicmouse with my later-added built-in bluetooth module/adapter on both windows and ubuntu i have been trying to tweak the magicmouse scrolling speed with commands rmmod something, modprobe hid_magicmouse --scroll_speed=45 --scroll_acceleration=30 or something, then added a file `/etc/modprobe.d/magicmouse.conf". the mouse seemed to be working fine with these changes. now if i run commands like hcitool dev, the shell tells me that i do not have any "Devices" or "adapters". i seem to have bluez installed, because when i type "blue" then tab-autocomplete, a bunch of commands like bluez-test-device pops up. -- update -- some commands and their results: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool dev Devices: easoncxz@eason-Aspire-4741-ubuntu:/etc$ hcitool scan Device is not available: No such device easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: no Hard blocked: no easoncxz@eason-Aspire-4741-ubuntu:/etc$ rfkill list 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: yes Hard blocked: no 2: acer-bluetooth: Bluetooth Soft blocked: yes Hard blocked: no

  • How does a one-man developer do its games' sounds?

    - by Gustavo Maciel
    Before anything, that's not a "oh, where can I find resources?" question. Well, I've been curious about one thing in the indie games industry. For the development of the game, such tasks like game design, art, sketches, code programming and etc can be easily done by just one person. You can just take up a paper and pencil and you're a game designer. You can just take software like Photoshop or Paint and you're an artist, a scanner and you're a sketcher, a compiler and you're a programmer. For sound it's different. You may tell me: Well, follow the line, take a lot of instruments and record it. But all we know that things don't work this way. I can list up some changes for us: External noises are a big problem, sound effects can't be made with instruments, it can't sound like a recorded and clipped sound. Well I can imagine how they do this in large companies, with such big studios and etc. But to summarise, my question is: What's the best way for a one-man indie to do all its sound? Does he have to synthesize everything? Record and buy some crazy program for editing sounds?

  • How does one rein in the complexities of web development ?

    - by Rahul
    I have been a server-side programmer for most of my career and have only recently started spending more time on web development. I am amazed at the number of things I need to master in order to write a decent web application. Just to list down a few tools/technologies I need to learn, Server side programming language (Java/JSP, ASP, PHP, Ruby or something else) A decent web framework (for any medium to big size application). HTML & CSS Javascript Javascript library (JQuery/ExtJS etc. primarily for AJAX). Good to know even if not necessary. At least a basic knowledge of web design - layouts, colors, fonts etc. A good understanding of web security. A good understanding of Performance/scalability issues. Testing, browser compatibility issues etc. The list goes on. So, my question to seasoned web developers is - How do you guys manage to learn and keep yourself updated on so many things? While developing a web application, how do you handle the complexities involved in these areas and yet manage to write an application that is well designed, user friendly, secure, performant and scalable. As a web developer, does one have to be a jack of all trades or should one specialize in one or two areas and leave the rest to other members of the team ?

  • Using Mercurial repository inside a Git one: Feasible? Sane?

    - by Portablejim
    I am thinking on creating a Mercurial repository under a Git repository. e.g. ..../git-repository/directory/hg-repo/ The 2 repositories Is it possible to manage (keeping your sanity)? How similiar is it to this? I am a computer science student at University. I manage my work in Git, mainly as a distribution mechanism (after realizing that rsync fails when you have changes in more than one place) between my desktop and usb drive. I try use of Git as a VCS as I do work. I have finished a semester where I did a small group project to prepare for a larger group project next year. We had to use Subversion, and experienced the joys of a centralised VCS (including downtime). I tried to keep the subversion repository separate to my Git repository for the subject**, however it was annoying that it was seperate (not in the place where I store assignments). I therefore moved to using an Subversion repository inside my Git repository. As I think ahead (maybe I am thinking too far ahead) I realise that I will have to try and convince people to use a DVCS and Mercurial will probably be the one that is preferred (Windows and Mac GUI support, closer to Subversion). Having done some research into the whole Git vs Mercurial debate (however not used Mercurial at all) I still prefer Git. Can I have a Mercurial repository inside a Git one without going mad (or it ruining something)? Or is it something that I should not consider at all? (Or is it a bad question that should be deleted?) ** I think outside of Australia it is called a course

  • How to make it so units don't stack up in one location?

    - by Daggio
    So I'm making a game in AS3, it's a strategy DotA-like game (for flash game equivalent, there's UDE) so far so good, I have the A* pathfinding algorithm all sorted out and the minion units move to the desired location as I want them to be. The problem a rise when a unit stops in a node that has already occupied by another friendly unit. Both (or more than two) of them stacks up in one location, it looks like they're one unit. I want to add collision detection so when they collide they don't stack up together. But now they stop when they collide on they way to a node. This isn't good because they won't move at all midway (they won't respond to enemy attacks like that). I've added a deltatime so they only stopped for 2 seconds before they move again to their designated designation. This moves them again but they flicker. Not how I want it. So, like the title said. How to make more than one units don't stack up in a node? And if possible, how to make them not flicker while moving (it's good if they can tell other friendly units on the way and avoid them accordingly)?
