  • KVM swtitch , screen resolution problem

    - by Vagelism
    I use the lates ubuntu version. Till to day I use it with an acer trravelmate4070 and an LG screen in order to expand my destkop. Works great. Till today that I desided to connect my LG screen to a KVM switch in order to share the big screen with an other pc when I need it. In the KVM switch the resolution is lower and I can not manually change it. I read many solutions about making an .conf file but since I am new to Ubuntu I am afraid , more over I realized that these articles talk for the same problem but not as an expantion screen but as a main screen. Any idea how to config correct this file? I send the links of these articles here: http://robert.penz.name/219/workarou...-kvm-switches/ Where is the X.org config file? How do I configure X there? Thank you!

  • How to produce assets effectively on large Flash game projects?

    - by Antoine Lassauzay
    I have been working on Flash games professionally for two years now and somehow, having our artists producing assets the right way is one of our biggest challenge. More precisely, it is very hard to have them following any kind of structure and/or standards, nor taking into consideration performance. I would say also the most of our issues concerns UI and related animations. Our current workflow is (on a Facebook hidden object game) : Artists produce PSD and animate prototypes in Flash Artists re-organize their FLA files to be a bit more "programmer friendly" Programmers retouches assets until they have the right structure and export classes inside a SWC, from Flash Programmers try to improve performances, sometimes degrading the quality of game graphics Our main idea is to hire somebody dedicated to prepare assets for programmers but I am really looking forward to improving the pipeline. I was wondering if you guys have tips of any kind to improve this workflow, whether it be team organization, training, tools or tips with Flash. Any explanation on your asset pipeline is well appreciated too.

  • Can I use a genetic algorithm for balancing character builds?

    - by Renan Malke Stigliani
    I'm starting to build a online PVP (duel like, one-on-one) game, where there is leveling, skill points, special attacks and all the common stuff. Since I have never done anything like this, I'm still thinking about the math behind the levels/skills/specials balance. So I thought a good way of testing the best builds/combos, would be to implement a Genetic Algorithm. It'd be like this: Generate a big group of random characters Make them fight, level them up accordingly to their victories(more XP)/losses(less XP) Mate the winners, crossing their builds, to try and make even better characters Add some more random chars, emulating new players Repeat the process for some time, or util I find some chars who can beat everyone's butt I could then play with the math and try to find better balances to make sure that the top x% of chars would be a mix of various build types. So, is it a good idea, or is there some other, easier method to do the balancing?

  • 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.

  • Ubuntu Desktop Password

    - by doug
    I inherited a machine with Ubuntu desktop installed. It has a password in place and I have no idea what the password may be. I cannot get to the command line to use the methods I have found online. No matter how many times I press "Shift" during the boot process it still goes all the way to the desktop login. I never see grub. I am not sure which version I have but I think may be 9 or 10. Thanks Doug

  • Partnering with a web designer to build and launch websites for fun. Where should I look for someone? [closed]

    - by FastCoder
    I have been working with web sites and web development for a long time and as a result I am able to build and launch complex websites (social network, dating site, stackoverflow, etc.) in little time (1-3 weeks). Problem is: I know very little about CSS, page layout, photoshop and graphic design. Of course I know HTML but when it comes to putting together something that looks good I am horrible. I just don't have the artistic skills. I wanted to launch some websites without any silly or naive intent to take over the world. Just for fun and to improve the portfolio. How do you guys recommend that I approach this problem of "finding this right partner" with the same mindset? Where should I look for this person? I have no idea... :(

  • March 2010 Chicago Architects Group Wrap Up

    - by Tim Murphy
    I would like to thank everyone who came out to last night’s event and especially thank Mike Vogt for the presentation. I think at first everyone glassed over since very few of us spend a lot of time with Integration Architecture and most of us live more in the application architecture space.  Learning about subject like BPEL and BPMN was refreshing. The discussion after Mike’s talk was lively and I think that everyone came away with a good idea of areas they might want to know more about.  People stuck around long after the meeting was over. If you are interested in the topic you can find the slides here. Be sure to join us next month when Matt Hidinger talks about Onion Architecture.  Details are coming soon. del.icio.us Tags: CAG,Chicago Architects Group

  • Print to File in Black and White (not in greyscale)

    - by user2413
    Hi all, I have these pdf files of c++code and they are colored which would be cool, except that the network printer here is b&w and the printed out codes come in various shades of pale grey which makes them essentially unreadable (specially the comments). I would like everything (text, codes, commands,...) to be printed in the same (black) color. i've tried fuddling with the printer's properties, but the closest thing i see is the 'level of grey' tab, and there i have the choice between 'enhanced' and 'normal' (and it doesn't make a difference in my case). i've tried 'print to file', but i don't see any options there to print to b&w, I've tried installing the 'generic cups printer', but again no options to print to b&w. any idea ? (i'm on 10.10)

  • Tiled game: how to correct load background image ?

    - by stighy
    Hi, i'm a newbie. I'm trying to develop a 2d game (top-down view). I would like to load a standard background, a textured ground... My "world" is big, for example 3000px X 3000px. I think it is not a good idea to load a 3000px x 3000px image and move it... So, how is the best practice ? To load a single small image (64x64) and repeat it for N times ? If yes, ok, but how i can manage the "background" movement ? Thanks Bye!

  • Cannot install eclipse due to broken packages

    - by Achim
    Trying to install eclipse, I get the following error: XXX:~$ sudo apt-get install eclipse Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: eclipse : Depends: eclipse-jdt (>= 3.8.0~rc4-1ubuntu1) but it is not going to be installed Depends: eclipse-pde (>= 3.8.0~rc4-1ubuntu1) but it is not going to be installed E: Unable to correct problems, you have held broken packages. I have no idea how to solve it. I'm quite new to Ubuntu, but I don't think that I'm using a unstable distribution. But I have added the repository which is required to install Tomcat7. Could that cause the problem?

  • How can I fit a rectangle to an irregular shape?

    - by Anil gupta
    I used masking for breaking an image into the below pattern. Now that it's broken into different pieces I need to make a rectangle of each piece. I need to drag the broken pieces and adjust to the correct position so I can reconstruct the image. To drag and put at the right position I need to make the pieces rectangles but I am not getting the idea of how to make rectangles out of these irregular shapes. How can I make rectangles for manipulating these pieces? This is a follow up to my previous question.

  • MS Grad Student Project

    - by Bernie Perez
    I'm a computer science grad student at UCLA specializing in security and/or mobile devices. I'm looking for ideas for my M.S. Project. Something with research and experimenting or testing. I have a few in mind, just wondering if the community has some good thoughts. I'm currently working on a project that deals with offload security related operations to a grid-powered/cloud server to improve battery life on phones or tablets, aka Security-Aware software on mobile devices. I might be able to expand on this for my project... but I'm open to any new types of ideas. I have another idea about secure communications with a peer-2-peer ad-hoc network, but its seems a little dull. Hope this questions is not off topic for this StackExchange. I look forward to hearing your thoughts and ideas.

  • How do I ask google not to index certain parts of my page?

    - by Gavin Mannion
    I was searching for an old review on my site today and I noticed that Google is indexing the headline text in my latest article list on every page that it appears, obviously I guess. The problem is if I search for my Dragon's Lair review specifically to my site like this http://www.google.co.za/search?sugexp=chrome,mod=9&sourceid=chrome&ie=UTF-8&q=site%3Alazygamer.net+dragons+lair+review Then it returns a ton of pages that aren't appropriate as they aren't related to the review at all. The reason why I care is that I have a second Dragon's Lair review that was posted years ago and now I can't find it. Is there a way to hint to google that certain text isn't relevant to the actual content on the page? is it a terrible idea?

  • Macbook Pro 8,1 - wireless interface not showing up

    - by Florian Margaine
    I've installed Ubuntu 11.10 on my Macbook Pro 8,1. Everything went fine and everything installs fine except for the wireless interface. I've installed the b43 module according to these instructions: https://help.ubuntu.com/community/MacBookPro8-1/Natty#Wireless I've tried compiling the module, ndiswrapper and also the last solution mentioned using this PPA: ppa:zwaldowski/ppa. With the three solutions, the module loads finely. It works smoothly. lspci shows the wireless card without problem. But there is no wireless interface. iwconfig or ifconfig both show eth0 and lo as interfaces, but no eth1 or wlan0 interface is showing up. I have no idea why, and I'm completely stuck there.

  • Junior developer support

    - by lady_killer
    I am a junior developer in my first work experience after university. I joined the company as PHP developer but I ended up developing using C# and ASP.NET. Right from the start I did not receive any training in C# and I was assigned with ASP projects with quite tight deadlines scoped by Senior developers. The few project hand overs I had from other developers were brief and it looked like I had to discover the system myself, in really short time. This is my first job as web developer and I wonder whether it is normal not to have a kind of mentor to show me how to do things, especially because I am completely new to the technology. Also, do you have idea how to tackle this? As you can imagine, it gets really frustrating! Thank you!

  • How can an experienced web developer transition to desktop development?

    - by Craige
    I'm a web developer, first and foremost. I've been programming for 5 or 6 years now, all of which has been web-based. I'm good at my job, both specifically as a web developer and as a programmer in general. I have decided recently that I would like to learn some desktop programming to to beef up my skill-set. My question is this: How can an experienced web developer transition to desktop development? To elaborate: I have always been a web-developer, and I can design and build web-applications without any problem. When it comes to sitting down with a to learn some desktop oriented programming, my problem isn't with any of the technical matters, but rather coming up with an idea to program. I draw a blank.

  • Why Google skips page title

    - by Bob
    I have no idea why this is happening. An example http://www.londonofficespace.com/ofdj17062004934429t.htm Title tag is: Unfurnished Office Space Wimbledon – Serviced Office on Lombard Road SW19 But is indexed as: Lombard Road – SW19 - London Office Space If you look in the source code and search for this portion ‘Lombard Road – SW19’ You then find that it's next to an office image alt=’Lombard Road – SW19’. The only thing I could think of is that the spider somehow ‘skips’ our title tag and grabs this bit, and then inserts the name of the site (but WHY?) Is there anything I can do with this? or is this a Google behaviour?

  • Why is there still so much offer for Perl programmers?

    - by user491444
    A quick search on monster.com on different scripting languages resulted on Perl having much more job opportunities than Python and Ruby (in Europe, I didn't check for the rest of the world), and since I'm just a newbie programmer I was wondering why is this? I've read everywhere that Python and Ruby are much better languages, and much more organized. Having coded in python and php myself, Perl's code seems so alien to me. Anyways, sorry for my poor English, it's my second language, and this is not a critique on the Perl language, I was just wondering whether it's a good idea to learn it at this point or not.

I re-created the USB drive with 11.04 and it booted fine. These were both 32 bit versions even though the laptop is a 64 bit. I was trying to create a generic boot USB that would work on everything I might try it on. What is the consensus on this idea? Any solution to the above error? Thanks from a noobe.

  • Hack Your Lights for Remote Control

    - by Jason Fitzpatrick
    This clever hack combines a modified wall switch with unused buttons on a universal remote to create one-touch wireless control of the lighting in a media room. Andrew, the tinker behind this home theater hack, writes: I really liked the idea of controlling my “Home Theater” lights with a remote (TV or other), this would save me the exhausting task of heaving myself off the couch to turn the lights on or off. I found one of my remotes has a spare power button, its one of those stupid “universal” remotes that comes with DVD players or TVs but only work if you have all the same brand equipment, I don’t so this made a good option for a light switch.

  • Messaging technologies between applications ?

    - by Samuel
    Recently, I had to create a program to send messages between two winforms executable. I used a tool with simple built-in functionalities to prevent having to figure out all the ins and outs of this vast quantity of protocols that exist. But now, I'm ready to learn more about the internals difference between each of theses protocols. I googled a couple of them but it would be greatly appreciate to have a good reference book that gives me a clean idea of how each protocol works and what are the pros and cons in a couple of context. Here is a list of nice protocols that I found: Shared memory TCP List item Named Pipe File Mapping Mailslots MSMQ (Microsoft Queue Solution) WCF I know that all of these protocols are not specific to a language, it would be nice if example could be in .net. Thank you very much.
