• Browser-based MMOs (WebGL, WebSocket)

  - by Alon Gubkin

  Do you think it is technically possible to write a fully-fledged 3D MMO client with Browser JavaScript - WebGL for graphics, and WebSocket for Networking? Do you think future MMOs (and games generally) will wrriten with WebGL? Does today's JavaScript performance allow this? Let's say your development team was you as a developer, and another model creator (artist). Would you use a library like SceneJS for the game, or write straight WebGL? If you would use a library, but not SceneJS, please specify which. UPDATE (September 2012): RuneScape, which is a very popular 3D browser-based MMORPG that used Java Applets so far has announced that it will use HTML5 for their client (source).

• Lost transparency in SDL surfaces drawn manually

  - by Christian Ivicevic

  I want to create SDL_Surface objects for each layer of my 2d tile-based map so that I have to render only one surface per layer rather than too many tiles. With normal tiles which do not have transparent areas this works well, however I am not able to create a SDL_Surface with transparent pixels everywhere to be able to draw some tiles on specific parts which should be visible (I do NOT want the whole surface to appear with a specific opacity - I want to create overlaying tiles where one can look through). Currently I am creating my layers like this to draw with SDL_BlitSurface on them: SDL_Surface* layer = SDL_CreateRGBSurface( SDL_HWSURFACE | SDL_SRCALPHA, layerWidth, layerHeight, 32, 0, 0, 0, 0); If you have a look at this screenshot I have provided here you can see that the bottom layer with no transparent parts gets rendered correctly. However the overlay with the tree tile (which is transparent in the top left corner) is drawn own its own surface which is black and not transparent as expected. The expected result (concerning the transparency) can be seen here Can anyone explain me how to handle surfaces which are actually transparent rather than drawing all my overlay tiles separately?

• Why have trackballs almost disappeared? [closed]

  - by Gary M. Mugford

  One of the movement sensors in my Microsoft Trackball Explorer has failed and right now I am using a mouse. Ugggh! I'll got steal one of the various Logitech trackballs spread around the house, but they all have issues. The Trackman has a horrible placement for the scroll wheel. Others have marbles for the thumb rather than a big ball for the fingers and at least one trackball is working around here without having a scroll wheel at all! (The one at the dinner table, for when I dine alone). My question is, why have trackballs fallen into disfavour? Seems to me that trackballs are great for crowded desktops (you know, the one with keyboards, notes, pens and coffee cups), and for laptops with those hated overly-sensitive touchpads. But right now, it seems to be a choice between that Logitech Trackman and some Kensington models that lack scroll wheels. All I want is a nice big ball to manipulate with the fingers and two buttons on the thumb side with the scroil wheel between them. Placement of other buttons is completely optional. Is that asking too much?

• Screen goes nuts and unreadable

  - by ChazD

  Running Ubuntu 10.10 in its own partition, also have Oracle Virtualbox 4 with Windows XP. Because i previously had a problem with a dark screen when i let the laptop on and i didn't use it for a long while i had set Power settings to Never sleep, never let the Display sleep. Monitor on install set to Laptop resolution 1400 by 1050, refresh rate 60 Hz, rotation Normal. The problem was when the computer was left on and i returned after about an hour, the screen was unreadable, similar to what used to happen to graphics cards before multisync became normal. So it appears as though the graphics card was asked to use a resolution it couldn't handle and went nuts. I had to power off the system, on restart everything was fine. Thanks for any suggestions.

• See former key sequences in vim

  - by Vasiliy Sharapov

  Sometimes I share screen shots and clips of vim usage with others. It would be nice to expand on the part of the status bar highlighted in this picture: I would like some way to make previous key sequences visible as well, such as: y2w jj f[ p 2d - You can see the key sequences leading up to the current one. I'll elaborate on my wish list at the bottom. Is something like this is available as a plugin or vim script? The sheer number of scripts available on vim online makes this hard to find by keyword. Some features I would hope for (but seem improbable): Delimit key sequences with a non-keyboard character instead of space, and a different one for the current command, so y2w jj f[ p 2d might become y2w¦jj¦f[¦p » 2d Replace keys that have a letter alternative with the alternative, such as the right arrow key - ^[[C with the equivalent l. Edit: To clarify, the right arrow key is a valid key in vim, but has no character to represent it, the l key preforms the same function and could/should substitute it. Have previous keystrokes run all the way to the beginning of the line (instead of just one or two), and just have vim's command prompt overwrite it when necessary. Replace some keystrokes with a more elegant alternative, for example hhhhh with 5h or more impressively d2f) with d% (in the appropriate situation).

• Oracle Social Network Developer Challenge Winners

  - by kellsey.ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. Now that OpenWorld 2012 has wrapped, I have time to tell you all about what happened. Maybe you recall that Noel (@noelportugal) and I were running a modified hackathon during the show, the Oracle Social Network Developer Challenge. Without further ado, congratulations to Dimitri Gielis (@dgielis) and Martin Giffy D’Souza (@martindsouza) on their winning entry, an integration between Oracle APEX and Oracle Social Network that integrates feedback and bug submission with Oracle Social Network Conversations, allowing developers, end-users and project leaders to view and discuss the feedback on their APEX applications from within Oracle Social Network. Update: Bob Rhubart of OTN (@brhubart) interviewed Dimitri and Martin right after their big win. Money quote from Dimitri when asked what he’d buy with the $500 in Amazon gift cards, “Oracle Social Network.” Nice one. In their own words: In the developers perspective it’s important to get feedback soon, so after a first iteration and end-users start to test, they can give feedback of the application. Previously it stopped there, and it was up to the developer to communicate further with email, phone etc. With OSN every feedback and communication gets logged and other people can see the discussion immediately as well. For the end users perspective he can now communicate in a more efficient way to not only the developers, but also between themselves. Maybe many end-users (in different locations) would like to change some behaviour, by using OSN they can see the entry somebody put in with a screenshot and they can just start to chat about it. Some key technical end users can have lighten the tasks of the development team by looking at the feedback first and start to communicate with their peers. For the project manager he has now the ability to really see what communication has taken place in certain areas and can make decisions on that. Later, if things come up again, he can always go back in OSN and see what was said at that moment in time. Integrating OSN in the APEX applications enhances the user experience, makes the lives of the developers easier and gives a better overview to project managers. Incidentally, you may already know Dimitri and Martin, since both are Oracle Ace Directors. I ran into Martin at the Ace Director briefings Friday before the conference started, and at that point, he wasn’t sure he’d have time to enter the Challenge. After some coaxing, he and Dimitri agreed to give it a go and banged out their entry on Tuesday night, or more accurately, very early Wednesday morning, the day of the Challenge judging. I think they said it took them about four hours of hardcore coding to get it done, very much like a traditional hackathon, which is essentially a code sprint from idea to finished product. Here are some screenshots of the workflow they built. #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } I love this idea, i.e. closing the loop between web developers and users, a very common pain point, and so did our judges. Speaking of, special thanks to our panel of three judges: Reggie Bradford (@reggiebradford), serial entrepreneur, founder of Vitrue and SVP of Cloud Product Development at Oracle Robert Hipps (@roberthipps), VP of Development for Oracle Social Network and my former boss Roland Smart (@rsmartx), VP of Social Marketing and the brains behind the Oracle Social Developer Community Finally, thanks to everyone who made this possible, including: The three other teams from HarQen (@harqen), TEAM Informatics (@teaminformatics) and Fishbowl Solutions (@fishbowle20) featuring Friend of the ‘Lab John Sim (@jrsim_uix), who finished and presented entries. I’ll be posting the details of their work this week. The one guy who finished an entry, but couldn’t make the judging, Bex Huff (@bex). Bex rallied from a hospitalization due to an allergic reaction during the show; he’s fine, don’t worry. I’ll post details of his work next week, too. The 40-plus people who registered to compete in the Challenge. Noel for all his hard work, sample code, and flying monkey target, more on that to come. The Oracle Social Network development team for supporting this event. Everyone in legal and the beta program office for their help. And finally, the Oracle Technology Network (@oracletechnet) for hosting the event and providing countless hours of operational and moral support. Sorry if I’ve missed some people, since this was a huge team effort. This event was a big success, and we plan to do similar events in the future. Stay tuned to this channel for more.

• Hardening non-root standalone Linux Tomcat install

  - by NoozNooz42

  I want to know if you have any tips as to how to strengthen the security of a non-root install of Tomcat in standalone mode once Tomcat is already installed in a non-root account, in standalone mode. I precise this because, for example, I'm not at all interested by the answers given here (because both Java and Tomcat requires root priviledges there to be installed and I've got zero interest in running jsvc): http://serverfault.com/questions/43765 So far, here's what I've done for my non-root standalone Tomcat 6 install: download and install the JRE .bin provided by Oracle/Sun (no need to be root here) (no need for a full JDK anymore right seen that Jasper [Tomcat's JSP engine] has its own compiler now right?) download and tar -xzf tomcat 6 (no need to be root here) set up transparent port-forwarding (must be root here) Note that my distribution is a Debian one and I have exactly zero interest in downloading Debian package / backports / whatever... Because, once again, I DO NOT want to need to be root to install Java & Tomcat. The only moment I needed to be root was to configure the firewall to transparently do the port forwarding 80 <-- 8080 and 443 <-- 8443. I then deleted all the default webapps but one: cd ~/apache-tomcat-6.0.26/webapps rm -rf docs rm -rf examples/ rm -rf manager/ rm -rf ROOT/ What about the directory ~/apache-tomcat-6.0.26/webapps/host-manager, do I need it or can I delete it? So, once I've installed Tomcat standalone in a non-root account (and taken into account that I don't want to enter the root password anymore and that I don't plan to install the whole Apache shebang), what more can I do? Are there connectors I can disable? (how?)

• What is the best practice to move sprites using mouse order in Tile games?

  - by Robin-Hood

  I am trying to make my first Tile-game using XNA. I have no problem drawing the map layers using TiledLib from codeplex, but, now I want to give sprite an (order) to move to a specific position on map, by selecting the sprite (left mouse click) and then right mouse click somewhere on the map to specify the target position. I don’t know what is the best practice to move sprite this way, considering that there may be collision objects in the direct path. what is the best practice to do this? Is there any demo covering this issue? thanks. BTW: I couldn’t upload snapshot because of my low score :(

• Moving symlinks into a folder based on id3 tags.

  - by Reti

  I'm trying to get my music folder into something sensible. Right now, I have all my music stored in /home/foo so I have all of the albums soft linked to ~/music. I want the structure to be ~/music/<artist>/<album> I've got all of the symlinks into ~/music right now so I just need to get the symlinks into the proper structure. I'm trying to do this by delving into the symlinked album, getting the artist name with id3info. I can do this, but I can't seem to get it to work correctly. for i in $( find -L $i -name "*.mp3" -printf "%h\n") do echo "$i" #testing purposes #find its artist #the stuff after read file just cuts up id3info to get just the artist name #$artist = find -L $i -name "*.mp3" | read file; id3info $file | grep TPE | sed "s|.*: \(.*\)|\1|"|head -n1 #move it to correct artist folder #mv "$i" "$artist" done Now, it does find the correct folder, but every time there is a space in the dir name it makes it a newline. Here's a sample of what I'm trying to do $ ls DJ Exortius/ The Trance Mix 3 Wanderlust - DJ Exortius [TRANCE DEEP VOCAL TECH]@ I'm trying to mv The Trance Mix 3 Wanderlust - DJ Exortius [TRANCE DEEP VOCAL TECH]@ into the real directory DJ Exortius. DJ Exortius already exists, so it's just a matter of moving it into the correct directory that's based on the id3 tag of the mp3 inside. Thanks! PS: I've tried easytag, but when I restructure the album, it moves it from /home/foo which is not what I want.

• ASSIMP in my program is much slower to import than ASSIMP view program

  - by Marco

  The problem is really simple: if I try to load with the function aiImportFileExWithProperties a big model in my software (around 200.000 vertices), it takes more than one minute. If I try to load the very same model with ASSIMP view, it takes 2 seconds. For this comparison, both my software and Assimp view are using the dll version of the library at 64 bit, compiled by myself (Assimp64.dll). This is the relevant piece of code in my software // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones. Necessary for our (limited) hardware skinning shader 0; cout << "Loading " << pFile << "... "; aiPropertyStore* props = aiCreatePropertyStore(); aiSetImportPropertyInteger(props,AI_CONFIG_IMPORT_TER_MAKE_UVS,1); aiSetImportPropertyFloat(props,AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE,80.f); aiSetImportPropertyInteger(props,AI_CONFIG_PP_SBP_REMOVE, aiPrimitiveType_LINE | aiPrimitiveType_POINT); aiSetImportPropertyInteger(props,AI_CONFIG_GLOB_MEASURE_TIME,1); //aiSetImportPropertyInteger(props,AI_CONFIG_PP_PTV_KEEP_HIERARCHY,1); // Call ASSIMPs C-API to load the file scene = (aiScene*)aiImportFileExWithProperties(pFile.c_str(), ppsteps | /* default pp steps */ aiProcess_GenSmoothNormals | // generate smooth normal vectors if not existing aiProcess_SplitLargeMeshes | // split large, unrenderable meshes into submeshes aiProcess_Triangulate | // triangulate polygons with more than 3 edges //aiProcess_ConvertToLeftHanded | // convert everything to D3D left handed space aiProcess_SortByPType | // make 'clean' meshes which consist of a single typ of primitives 0, NULL, props); aiReleasePropertyStore(props); if(!scene){ cout << aiGetErrorString() << endl; return 0; } this is the relevant piece of code in assimp view code // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones.

What could be the reason for such a difference in performance? The two software are using the same dll Assimp64.dll (compiled in my computer with vc++ 2010 express) and the same function aiImportFileExWithProperties to load the model, so I assume that the actual code employed is the same. How is it possible that the function aiImportFileExWithProperties is 100 times slower when called by my sotware than when called by assimp view? What am I missing? I am not good with dll, dynamic and static libraries so I might be missing something obvious. ------------------------------ UPDATE I found out the reason why the code is going slower. Basically I was running my software with "Start debugging" in VC++ 2010 Express. If I run the code outside VC++ 2010 I get same performance of assimp view. However now I have a new question. Why does the dll perform slower in VC++ debugging? I compiled it in release mode without debugging information. Is there any way to have the dll go fast in debugmode i.e. not debugging the dll? Because I am interested in debugging only my own code, not the dll that I assume is already working fine. I do not want to wait 2 minutes every time I want to load my software to debug. Does this request make sense?

• Is Python worth learning? Is it a useful tool? [closed]

  - by Kenneth

  I recently had a discussion with a professor of mine on the topic of web development. I had recently decided I would learn python to increase my arsenal of web tools which I mentioned to him at that time. He almost immediately asked why I would waste my time on that. I'm not certain but I think he recently started in on researching and studying web development so he could pick up the web development classes that haven't been taught for a while after the previous professor who taught those classes left. I've heard a lot about python and thought maybe he was mistaken about its usefulness. Is python a useful tool to have? What applications can it be used for? Is it better than other similar alternatives? Does it have useful applications outside of web development as well?

• Oracle Social Network Developer Challenge: Bezzotech

  - by Kellsey Ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. I’ve covered all the entries we had for the Oracle Social Network Developer Challenge, the winners, Dimitri and Martin, HarQen, TEAM Informatics and John Sim from Fishbowl Solutions, and today, I’m giving you bonus coverage. Friend of the ‘Lab, Bex Huff (@bex) from Bezzotech (@bezzotech), had an interesting OpenWorld. He rebounded from an allergic reaction to finish his entry, Honey Badger, only to have his other OpenWorld commitments make him unable to present his work. Still, he did a bunch of work, and I want to make sure everyone knows about the Honey Badger. If you’re wondering about the name, it’s a meme; “honey badger don’t care.” Bex tackled a common problem with social tools by adding game mechanics to create an incentive for people to keep their profiles updated. He used a Hot-or-Not style comparison app that poses expertise questions and awards a badge to the winner. Questions are based on whatever attributes the business wants to emphasize. The goal is to find the mavens in an organization, give them praise and recognition, ideally creating incentive for everyone to raise their games. In his own words: There is a real information quality problem in social networks. In last year’s keynote, Larry Elison demonstrated how to use the social network to track down resources that have the skill sets needed for specific projects. But how well would that work in real life? People usually update that information with the basic profile information, but they rarely update their profiles with latest news items, projects, customers, or skills. It’s a pain. Or, put another way, when was the last time you updated your LinkedIn profile? Enter the Honey Badger! This is a example of a comparator app that gamifies the way people keep their profiles updated, which ensures higher quality data in the social network. An administrator comes up with a series of important questions: Who is a better communicator? Who is a better Java programmer? Who is a better team player? And people would have a space in their profile to give a justification as to why they have these skills. The second part of the app is the comparator. It randomly shows two people, their names, and their justification for why they have these skills. You will click on one of them to “vote” for them, then on the next page you will see the results from the previous match, and get 2 new people to vote on. Anybody with a winning score wins a “Honey Badge” to be displayed on their profile page, which proudly states that their peers agree that this person has those skills. Once a badge is won, it will be jealously guarded. The longer your go without updating your profile, the more likely it is that you will lose your badge. This “loss aversion” is well known in psychology, and is a strong incentive for people to keep their profiles up to date. If a user sees their rank drop from 90% to 60%, they will find the time to update their justification! Unfortunately, during the hackathon we were not allowed to modify the schema to allow for additional fields such as “justification.” So this hack is limited to just the one basic question: who is the bigger Honey Badger? Here are some shots of the Honey Badger application: #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } Thanks to Bex and everyone for participating in our challenge. Despite very little time to promote this event, we had a great turnout and creative and useful entries. The amount of work required to put together these final entries was significant, especially during a conference, and the judges and all of us involved were impressed at how much work everyone was able to do. Congrats to everyone, pat yourselves on the back. Stay tuned if you’re interested in challenges like these. We’ll likely be running similar events in the not-so-distant future.

• Migrating mysql 4 to mysql 5

  - by Lennart Regebro

  This seems to me to be a common use case, so I'm surprised so little information is about it, so sorry if it's a duplicate, but I have searched. :) I'm migrating a clients website from one CMS to another, and of moving to newer faster machines all at the same time. As a part of this I'm moving a MySQL database from the old server to the new ones. The problem is that the old server runs MySQL 4 and the new MySQL 5. So when i do a mysqldump at the old site and then try to run it on the new site I get syntax errors. ERROR 1064 (42000) at line 178: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'BTREE (`id`), KEY `f_ChangedOnWeb` (`f_ChangedOnWeb`), KEY `f_AddressUpdate`' at line 56 I also tried to use an even older syntax by dumping with --compatible mysql323, but that just resulted in ERROR 1062 (23000) at line 2283: Duplicate entry '??????????' for key 2`... It seems to me this must be a reasonably common use case, yet I can't find any sort of help on this. Possibly all my Google searches just drown in irrelevant answers. Most seem to agree that mysqldump is the right answer, but noone mentions that you can get syntax errors...

• How can I change my cursor behavior?

  - by Doug Clement

  When I am typing, my mouse cursor, if left on the text, will eventually auto-click in whatever space in the the text box I happen to be, causing me to type in the middle of a sentence. Also, the cursor in the text box will frequently stop mid-word and the screen will scroll down all of a sudden when pressing the space bar while typing. My question is, how do I change this behavior because it is driving me absolutely bat crap crazy. I have an Acer Aspire One D257 Netbook. I am not sure if it's a Xubuntu problem because it does this while I am using Windows 7 too. Any help would be nice, thanks!

• "Open file location" is broken for Win Live Photo Gallery and Chrome

  - by Arnold Spence

  Symptoms: Windows Live Photo Gallery: Right clicking on an image (.jpg, .png) and selecting the context menu item "Open file location" should open the containing folder in explorer. Instead, I get an error dialog stating "This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel." Chrome: After downloading a file (of any type), clicking the down arrow on the download status bar at the bottom and clicking "Show in folder" results in the same error dialog mentioned above. I'm using Windows 7. I'm pretty sure this is a registry entry gone bad but I've been unable to locate any information about this specific problem. It's not a file type association problem as I am not trying to open the files concerned, I'm trying to open an explorer window at the location for the file. I've found a similar issue that somebody had with explorer itself. However, the suggested registry fixes here for "Folder", "Directory" and "Drive" did not solve the problem. Also, If I use the searchbar in explorer to do a search, right click on a file and choose "Open file location", explorer jumps to that location without any trouble. I have not yet identified other programs with this issue.
