  • Techniques for lighting a texture (no shadows)

    - by Paul Manta
    I'm trying to learn about dynamic shadows for 2D graphics. While I understand the basic ideas behind determining what areas should be lit and which should be in shadow, I don't know how I would "lighten" a texture in the first place. Could you go over various popular techniques for lighting a texture and what (dis)advantages each one has? Also, how is lighting a texture with colored light different from using white light?

  • SQL Rally Voting Open

    - by AllenMWhite
    The voting for sessions for SQL Rally has been going on for a couple of weeks now. This week the Enterprise Database Administration & Deployment sessions are up for voting. I didn't go into politics because I don't feel comfortable telling people that they should vote for me but this is how the sessions are being decided for this conference, so here goes. I've submitted two abstracts, both grouped in the Summit Spotlight section. The first is a new session based on what I learned implementing...(read more)

  • How can you tell whether to use Composite Pattern or a Tree Structure, or a third implementation?

    - by Aske B.
    I have two client types, an "Observer"-type and a "Subject"-type. They're both associated with a hierarchy of groups. The Observer will receive (calendar) data from the groups it is associated with throughout the different hierarchies. This data is calculated by combining data from 'parent' groups of the group trying to collect data (each group can have only one parent). The Subject will be able to create the data (that the Observers will receive) in the groups they're associated with. When data is created in a group, all 'children' of the group will have the data as well, and they will be able to make their own version of a specific area of the data, but still linked to the original data created (in my specific implementation, the original data will contain time-period(s) and headline, while the subgroups specify the rest of the data for the receivers directly linked to their respective groups). However, when the Subject creates data, it has to check if all affected Observers have any data that conflicts with this, which means a huge recursive function, as far as I can understand. So I think this can be summed up to the fact that I need to be able to have a hierarchy that you can go up and down in, and some places be able to treat them as a whole (recursion, basically). Also, I'm not just aiming at a solution that works. I'm hoping to find a solution that is relatively easy to understand (architecture-wise at least) and also flexible enough to be able to easily receive additional functionality in the future. Is there a design pattern, or a good practice to go by, to solve this problem or similar hierarchy problems? EDIT: Here's the design I have: The "Phoenix"-class is named that way because I didn't think of an appropriate name yet. But besides this I need to be able to hide specific activities for specific observers, even though they are attached to them through the groups. A little Off-topic: Personally, I feel that I should be able to chop this problem down to smaller problems, but it escapes me how. I think it's because it involves multiple recursive functionalities that aren't associated with each other and different client types that needs to get information in different ways. I can't really wrap my head around it. If anyone can guide me in a direction of how to become better at encapsulating hierarchy problems, I'd be very glad to receive that as well.

  • Automatically change resolution when not in dock

    - by jwir3
    I have Ubuntu 11.04 (yep, I know it's old news) on my Lenovo W520. At home, I have a dock with dual monitors. I have a pretty decent setup - things work almost perfectly (hence the reason I'm reluctant to upgrade... that and I'm not 100% sold on Unity). Anyway, the only annoyance I have is that when I'm on travel, I use the laptop screen. When I un-dock the laptop, I need to manually go into nvidia x-server settings and change the resolution from 'Auto' to 1920x1200, or it will think I have two screens, and my mouse pointer will be able to go way off the left side of the screen. This isn't a big deal, but I need to do it every time I restart the x-server (so if I reboot, or have to kill it, etc...) What would be really nice is if there was a way for it to automatically detect whether or not there is external monitors (which it seems to do already), and switch into the mode I select, depending on which monitors are connected. Is there any way to accomplish this? I've posted my xorg.conf file for reference. # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 270.29 (buildd@allspice) Fri Feb 25 14:42:07 UTC 2011 # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 275.19 ([email protected]) Tue Jul 12 18:35:38 PDT 2011 #Section "Monitor" # Identifier "Monitor1" # VendorName "Lenovo" # ModelName "ThinkpadLCD" # #HorizSync 28.0 - 33.0 # #VertRefresh 43.0 - 72.0 # #Option "DPMS" #EndSection Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "DELL U2410" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 76.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro 1000M" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Section "Screen" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+120, DFP-6: nvidia-auto-select +1920+0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+120, DFP-5: nvidia-auto-select +1920+0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +1920+419, DFP-5: nvidia-auto-select +3840+0, DFP-6: nvidia-auto-select +0+0" # Removed Option "metamodes" "DFP-5: nvidia-auto-select +0+0, DFP-6: 1920x1200 +1920+0" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "NoLogo" "True" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "TwinView" "1" Option "metamodes" "DFP-5: nvidia-auto-select +1920+0, DFP-6: 1920x1200 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection

  • Using Drupal to build a directory listing? [on hold]

    - by Jim
    I am trying to create a form inside Drupal that will allow me to create a directory similar to this diagram: http://i.imgur.com/EtChBbG.jpg I tried looking into HTML tables but it is too basic for what I'm trying to do. How do I create a directory that can archive data in an alphabetical ordering? It also has to be able to sort by letters and other categories. Does anyone have an idea of how I should go about doing this? Thanks!

  • What research topics can I tackle with only a year of experience?

    - by rapidash
    I've been looking to get into research, but I'm not sure I can do when I've only taken two quarters of Computer Science. I go to the University of Washington, if it's relevant. This is a page on research. I find that I'm not able to judge what is possible for a first year looking through the website. Most things look intimidating, but I'm sure I could somewhere on some problem if I actually attacked it.

  • Windows Phone 7, taking the mobile out of mobile

    - by markritchie
    I’ll start off this blog entry with a little background which is necessary for you to understand my situation. I moved from to the UK to Germany about three years ago and while I can converse in German, English is still very much my first language and the language I want my content delivered in. I happily purchased a HTC HD7 when WP7 was released here in Germany thinking foolishly that Microsoft really would get internationalization and localization as it’s at the heart of their business and developer products. Overall I’m very happy with my WP7, the camera sucks but that’s more HTC’s fault that Microsoft, but other than that it’s a very promising platform. My problems started when I purchased my first app. Initially everything appeared to be fine and things were as smooth as things had been with my previous free applications, however about a month after I received an email from Zune informing me that the credit card that they had registered against my account had expired. No problem I foolishly thought; I’ll simply add a new one. I don’t want to bore you with the details of what I’ve been through other than to take the low-lights: trying numerous websites, posts on Microsoft Answers and a tweet to Microsoft Support all to no avail. Today somebody suggested that I call the Xbox support line in the UK as they had solved their billing problems this way. So I called up the Xbox support line since I hadn’t resolved the problem using the Zune portal to resolve my problem with my WP7 (anybody else thinks Microsoft might need some consolidation here). After being on the phone with a very friendly representative in Ireland I was informed that because my British credit card has a billing address in Germany they are unable to accept it as a credit card. Because my Live ID and Zune Tag are registered in the UK they cannot take my card. Their solution is that I have to create a new Zune Tag that has its locale in Germany and then associate it with my phone. Now, first thing I go to register for a Zune Tag with a German locale it very kindly switches into German for me, nothing quite like reading a EULA in a language you’re not fluent in. I’ve no idea how this will affect the apps that are available to me in the app store, and I’m pretty sure it means that all my Xbox live achievements will become history. And what if I was to move to say France at some point do I have to go through all this again? At the end of the day I’m trying to set something up so I can give them my money and they’re making it VERY difficult for me. Could you imagine walking into a book store when you were on holiday and being told by the clerk that they couldn’t take your credit card because you came from another country?

  • Spotlight on an office - Moscow

    - by Maria Sandu
    Probably the most famous place in Moscow, after Red Square, is the centre of Moscow. Here you can find beautiful buildings that seem to touch the sky, located on the banks of the river. In one of these high towers you can find the Oracle offices, friendly and modern. The stunning view will keep capture your attention for a couple of minutes and then you can enjoy a delicious coffee and take a seat at your desk, starting a new day. My name is Dmitry and I can tell you that we’re enjoying every minute spent in the office and that’s because of the pleasant atmosphere. As soon as you enter the offices, the friendly environment will make you feel more relaxed. Even though the space is split between the different departments, we interact and communicate a lot. We take our cup of coffee or tea together and discuss our achievements and all sort of subjects in the kitchen or in the open space. One of my favorite parts are the festive events when we celebrate with cakes and goodies. Any birthday or new arrival is a good reason for a tea party! We have some work-related traditions that help us as employees. One of them is the monthly Tech Hour when Experts from the Pre-sales team discuss technical topics and about the most recent innovations within the company. Lunch is another good opportunity to interact and chat. We have a variety of options, such as the two kitchens or the vast number of restaurants where you can serve up anything you want. As we are right in the centre of Moscow, you can choose between Sushi, Italian Pasta and all sorts of food. We usually go with our colleagues to have lunch. If you care about your health, I have very good news for you as nearby there are two first-class fitness centres with swimming pools, yoga and various sport classes that you can attend. My suggestion would be to either start or end your day with a visit to the swimming pool for a well-deserved hour of relaxation. As I mentioned before, we’re right in the heart of Moscow, so after work you can spend some time in the large shopping centers where you can choose between many different entertainment options. We often go to bowling or to the cinema. I hope I have given you a glimpse into working life at the Oracle offices in Moscow, a really great and pleasant place to work in, so follow us on http://campus.oracle.com for our latest vacancies and internships.

  • Different Link Building Methods

    Link building plays a very important role in making a website popular. It is a process of creating inbound links to your page. Link building is something that you should not launch into without knowing enough about it. If you are creating back links organically, it's perfectly okay but do not go on creating dozens of links without considering standard link building methods.

  • Is there an Ubuntu alternative to iExplorer (formerly iPhone Explorer)?

    - by nerdabilly
    I'm trying to view the entire contents of my iPhone in Ubuntu 10.04. I'm able to mount and view the digital media folders, but I'm looking for behavior more like the Mac/Windows iExplorer app that will list the /var folder as well as Applications, etc rather than just making it look like an external filesystem. I've found a few options that require jailbreak but I'd rather not go that route if it's at all possible. Thanks!

  • Why is my background image always disappearing when I log in?

    - by user64720
    When logging in lubuntu 12.04, my background image always disappears, leaving the screen with color only and then I have to go to definitions and set the image in the background again. I notice that this does not happen with low-resolution images, only with high ones, but also happens with images that fit my screen resolution (1280 X 720). Any ideas on how to fix this? The image remains at it's location, but on the desktop preferences, the pathway to the file location is lost and set to none.

  • Boosting That Return Rate

    I've noticed something about most beginner Internet marketers. They get really excited when they get traffic - even if that traffic doesn't convert to anything in the way of sales or proceeds. They're over the moon about the chance to make a profit. That's where they go wrong, unfortunately. It's fun to be excited at first, but after a week or so, reality really needs to set in and you need to start making decisions based on factors like conversions and ROI rather than raw traffic.

  • The cpuidle subsystem

    <b>LWN.net:</b> "Your editor recently had cause to dig around in the cpuidle subsystem. It never makes sense to let such work go to only a single purpose when it could be applied toward the creation of a kernel-page article. So, what follows is a multi-level discussion of cpuidle, what it's for, and how it works. Doing nothing, it turns out, is more complicated than one might think."
