  • How do I install oracle jdk 7 on ubuntu server 12.04?

    - by Muhammad Sholihin
    Folks, I'm new in ubuntu server. As I understand it, Oracle retired the Operating System Distributor's License for Java, meaning that Canonical could no longer include the JDK or JRE in their APT repositories.

How do I install oracle jdk 7 on ubuntu server 12.04? Thanks in advance

  • How to apply effects that occur (or change) over time to characters in a game?

    - by Joshua Harris
    So assume that I have a system that applies Effects to Characters like so: public class Character { private Collection<Effect> _effects; public void AddEffect (Effect e) { e.ApplyTo(this); _effects.Add(e); } public void RemoveEffect (Effect e) { e.RemoveFrom(this); _effects.Remove(e); } } public interface Effect { public void ApplyTo (Character character); public void RemoveFrom (Character character); } Example Effect: Armor Buff for 5 seconds. void someFunction() { // Do Stuff ... Timer armorTimer = new Timer(5 seconds); ArmorBuff armorbuff = new ArmorBuff(); character.AddEffect(armorBuff); armorTimer.Start(); // Do more stuff ... } // Some where else in code public void ArmorTimer_Complete() { character.RemoveEffect(armorBuff); } public class ArmorBuff implements Effect { public void applyTo(Character character) { character.changeArmor(20); } public void removeFrom(Character character) { character.changeArmor(-20); } } Ok, so this example would buff the Characters armor for 5 seconds. Easy to get working. But what about effects that change over the duration of the effect being applied. Two examples come to mind: Damage Over Time: 200 damage every second for 3 seconds. I could mimic this by applying an Effect that lasts for 1 second and has a counter set to 3, then when it is removed it could deal 200 damage, clone itself, decrement the counter of the clone, and apply the clone to the character. If it repeats this until the counter is 0, then you got a damage over time ability. I'm not a huge fan of this approach, but it does describe the behavior exactly. Degenerating Speed Boost: Gain a speed boost that degrades over 3 seconds until you return to your normal speed. This is a bit harder. I can basically do the same thing as above except having timers set to some portion of a second, such that they occur fast enough to give the appearance of degenerating smoothly over time (even though they are really just stepping down incrementally). I feel like you could get away with only 12 steps over a second (maybe less, I would have to test it and see), but this doesn't seem very elegant to me. The only other way to implement this effect would be to change the system so that the Character checks the _effects collection for effects that alter any of the properties any time that they are being used. I could handle this in functions like getCurrentSpeed() and getCurrentArmor(), but you can imagine how much of a hassle it would be to have that kind of overhead every time you want to do a calculation with movement speed (which would be every time you move your character). Is there a better way to deal with these kinds of effects or events?

  • Mounting a network filesystem into schroot

    - by haggai_e
    Hi, I'm using a network file system (AFS) and I would like to also mount it into my schroot. Adding a line to /etc/schroot/mount-defaults, with bind or rbind in the options didn't help: schroot always mounts the directory with bind, and it remains empty in the chroot. My current solution is a script that remounts the /afs directory with rbind after the schroot has been set up. Is there a way to make schroot use rbind directly?

  • Professional immigration

    - by etranger
    Hello all, Does anyone here have a practical advice on professional relocation from Russia to Europe? The reasons behind making such a decision are far beyond the subject, perhaps, so I'll stick to the practical part. Having done some of the "common stuff" for finding a job, I am now facing two serious problems: I am a "dual-class" person, with university degree in marketing, and multiple years of self-studied computer competence (hence my writing here). Have professional experience in both areas. I don't currently hold a European work permit. From what I can see, this results in normal HR person throwing out my CV as either being "overqualified" or "too much trouble with making the permit". I do have the skills and character to start my own business, but it requires start-up capital that I don't have, over the last years I had to pay high bills for medical treatment of my family member, who had deceased. Now, I'm almost out of debts. As you can probably guess, English is not a problem, and I'm open to new languages, but first steps of entering the market, or the society, is the problematic part. I live close to Norway, and am trying to get some professional contacts there, but it hasn't got me any practical perspective so far. Any advice is greatly appreciated. EDIT: I am currently making my living off web site development, and occasional consulting services both in IT and marketing. For purely geographic reasons I'm dealing with clients that reside in the same city where I live, pop. 350 000. Being quite local, market requirements for web sites are simple and stable — clients need to control navigation, write articles in a word-like editor, upload illustrations and place ad banners, all with no additional programming. As many web developers do, I'm using my own content management system that fits these expectations. I have also started developing a newer version of this system that has better support for international environments, but I'm too distant from the real market demand in Europe to speak of the right track here. Technically it's based on php/mysql and uses xslt for templating. It allows for quick website deployment, and has architectural neatness, lack of which made me abandon similar opensource solutions (Joomla and the like). Deploying time from rasterized design proofs is normally under 6-8 working hours, don't know how that compares to the world practice. EDIT 2: Can anyone share what Norwegian (Scandinavian) web solutions market currently demands?

  • Are UML class diagrams adequate to design javascript systems?

    - by Vandell
    Given that UML is oriented towards a more classic approach to object orientation, is it still usable in a reliable way to design javascript systems? One specific problem that I can see is that class diagrams are, in fact, a structural view of the system, and javascript is more behaviour driven, how can you deal with it? Please, keep in mind that I'm not talking abot the real world domain here, It's a model for the solution that I'm trying to achieve.

  • What operating systems are used in airplanes, and what programming languages are they developed in?

    - by adhg
    I was wondering if anyone knows what is the operating system used in commercial airplanes (say Boeing or Airbus). Also, what is the (preferred) real-time programing language? I heard that Ada is used in Boeing, so my question is - why Ada? what are the criteria the Boeing-guys had to choose this language? (I guess Java wouldn't be a great choice if the exactly in lift off the garbage collector wakes up).
