  • Why can't the Unity panel be hidden?

    - by newboldrob
    I am a light Linux user. I have Natty installed on my netbook and used to have it dual-booted on my Windows 7 PC. After a total refresh of my notebook off came Ubuntu and I'm back to basics over there. But HERE (I'm running Natty on a HP-Mini) I've decided to poke around a bit to get the best user experience on this little thing. I really like the Unity interface but really hate the static Unity Panel. I have no clue why it's even necessary to be on globally. After all, in the classic interface, both panels can autohide or get filed aside with buttons on either side of the bar. On a 10" screen, real estate is at a premium. What intrinsic purpose does the static unity panel hold for the OS? There has to be a great reason for this thing to HAVE to be here. It ONLY goes away in fullscreen apps and I can't use everything fullscreen Why can the unity panel not be hidden?

  • Optimal Compression for Speech

    - by ashes999
    I'm designing a game that depends heavily on audio; I will have some 300+ speech files (most of them just a word or two long). This can very quickly escalate the size of my final game. What's the optimal way to encode/compress speech files to keep the size minimal without getting audio artifacts? Please address both per-file compression/encoding, and also zipping/compressing the set of all speech files together in your answer. Because I'm not sure which (or combination of both) factors will give me the best results. Edit: I need this to run in Silverlight and Android, so I'm presumably stuck with only MP3 as my option (other than uncompressed wave files).

  • How can I refactor a code base while others rapidly commit to it?

    - by Incognito
    I'm on a private project that eventually will become open source. We have a few team members, talented enough with the technologies to build apps, but not dedicated developers who can write clean/beautiful and most importantly long-term maintainable code. I've set out to refactor the code base, but it's a bit unwieldy as someone in the team out in another country I'm not in regular contact with could be updating this totally separate thing. I know one solution is to communicate rapidly or adopt better PM practices, but we're just not that big yet. I just want to clean up the code and merge nicely into what he has updated. Would a branch be a suitable plan? A best-effort-merge? Something else?

  • is a wildcard SSL the only option in this multiple VHOST/1IP setup?

    - by solsol
    I have a web app set up that needs the following SSL encryption: secure.myapp.com -> SSL www.myapp.com/login -> SSL www.myapp.com/signup -> SSL If I'm correct, I could run one SSL certificate for my whole www.myapp.com/* pages. The problem is that I have a subdomain called secure.myapp.com that either needs to be on a separate IP address to work with SSL. Right now I have one server, one public IP and a number of Virtual Hosts in apache to make this work. I'd rather not buy an expensive Wildcard SSL certificate to secure just one subdomain. What is your advice on this? If it IS the only solution any tips on getting a price worthy wildcard SSL cert is appreciated. I have read about SNI that allows the use of multiple SSL certs, but not all browsers (IE6!) support this. Since we are building a web app for the public, we cannot have IE6 to run on unencrypted connections. Thanks for you help

  • Where is the Accessibility mouse click lock?

    - by user10133
    I've been a user of Linux on the desktop off and on again over the years. I very nearly switched my primary computer to Ubuntu prior to the release of Windows 7. There were a few, but significant issues at the time that prevented wholesale adoption, mostly tethering with my phone and lousy VPN Client. One key component I could count on was the Accessibility features. I have recently installed Ubuntu 10.10 and am considering giving it another try, but it appears Ubuntu has taken a leap backwards in that it no longer has a click lock feature for the mouse. Basically I need the ability to press and hold the left button to trigger a locking of the button so I can move the mouse by way of a trackpoint with my prosthesis. I absolutely require this feature and it is a deal breaker if it won't work. I've tried the Dwell keys but this is a chaotic control at best. I've never been able to manage a drag of any kind.

  • Is there a cross-platform special directory I can use for game save files?

    - by Suds
    I'm developing with LWJGL and Java on a Windows 7 laptop. I've successfully set up saving to the %appdata%\gamename\saves\ or long form c:\users\user\appdata\roaming\gamename\saves\ folder by using File dir = new File(System.getenv("APPDATA") + "\\gamename\\saves\\");. I have hobbyist level experience with Linux, and zero experience with OSX. My game will be fully cross platform. Is System.getenv("APPDATA"); cross platform? If so, where does it point to on Linux or OSX? Is there a best practices alternative that I should use?

  • What top companies look for in an Interview?

    - by Geek
    Basically I am looking for what is it that you goof up and you are out from the remaining process ? Are elimination rounds a fair way to judge a person ? Anyone can have a bad hour :-( Should you code the best possible or should you get the Algorithm right ? I generally first code a workable solution and then work on it till a level I think it looks beautiful to me. Is this a wrong approach ? Recently I had a telephonic interview in which I was asked to write a variation of Level Order traversal in 20 minutes. I could get the Algorithm and working code in 20 minutes but couldn't get the Exception handling and the coding convention right, after which I didn't hear back from them :-( All the other questions in the interview went very well this was the only thing which was 'not upto the mark'. Needless to say I like the company and will apply again but want to get it right the next time :-) Please share your experiences and valuable suggestions.

  • Oracle Cloud Applications: The Right Ingredients Baked In

The magic happens when you mix these ingredients together. The same goes for the hottest technologies fast changing how IT impacts our organizations today: cloud, social, mobile, and big data. By themselves they’re pretty good; combining them with a great recipe is what unlocks real transformation power. Choosing the right cloud can be very similar to choosing the right cake. First consider comparing the core ingredients that go into baking a cake and the core design principles in building a cloud-based application. For instance, if flour is the base ingredient of a cake, then rich functionality that spans complete business processes is the base of an enterprise-grade cloud. Cloud computing is more than just consuming an "application as service", and having someone else manage it for you. Rather, the value of cloud is about making your business more agile in the marketplace, and shortening the time it takes to deliver and adopt new innovation. It’s also about improving not only the efficiency at which we communicate but the actual quality of the information shared as well. Data from different systems, like ingredients in a cake, must also be blended together effectively and evaluated through a consolidated lens. When this doesn’t happen, for instance when data in your sales cloud doesn't seamlessly connect with your order management and other “back office” applications, the speed and quality of information can decrease drastically. It’s like mixing ingredients in a strainer with a straw – you just can’t bring it all together without losing something. Mixing ingredients is similar to bringing clouds together, and co-existing cloud applications with traditional on premise applications. This is where a shared services  platform built on open standards and Service Oriented Architecture (SOA) is critical. It’s essentially a cloud recipe that calls for not only great ingredients, but also ingredients you can get locally or most likely already have in your kitchen (or IT shop.) Open standards is the best way to deliver a cost effective, durable application integration strategy – regardless of where your apps are deployed. It’s also the best way to build your own cloud applications, or extend the ones you consume from a third party. Just like using standard ingredients and tools you already have in your kitchen, a standards based cloud enables your IT resources to ensure a cloud works easily with other systems. Your IT staff can also make changes using tools they are already familiar with. Or even more ideal, enable business users to actually tailor their experience without having to call upon IT for help at all. This frees IT resources to focus more on developing new innovative services for the organization vs. run and maintain. Carrying the cake analogy forward, you need to add all the ingredients in before you bake it. The same is true with a modern cloud. To harness the full power of cloud, you can’t leave out some of the most important ingredients and just layer them on top later. This is what a lot of our niche competitors have done when it comes to social, mobile, big data and analytics, and other key technologies impacting the way we do business. The transformational power of these technology trends comes from having a strategy from the get-go that combines them into a winning recipe, and delivers them in a unified way. In looking at ways Oracle’s cloud is different from other clouds – not only is breadth of functionality rich across functional pillars like CRM, HCM, ERP, etc. but it embeds social, mobile, and rich intelligence capabilities where they make the most sense across business processes. This strategy enables the Oracle Cloud to uniquely deliver on all three of these dimensions to help our customers unlock the full power of these transformational technologies.

  • Store VOD wmi data in a database directly or use CQRS?

    - by JD01
    I need to collect Video on demand bandwidth usage every few minutes (or maybe ever few seconds) and store this in a database so users can produce graphs on bandwidth usage over a period of time (few hours, days, weeks or even possibly months). So the sort of data that will be stored will be the number of users watching videos, current server bandwidth (Mb/s), multicast bit rate etc. I am wondering whether using CQRS would be a good approach with Event sourcing as I can then rebuild my objects to create different projections (I.e. different graphs/reports etc) but then again it seems like I am introducing complexity which might not be needed. Or would it be best to just put the data directly in a database (currently using PostGres) directly and query off that? Having thought about it, my table is a form of audit log anyway, so I don't think I need event sourcing at all. Any thoughts?

  • How to detect whether an Object came to sleep at a specific position?

    - by Nils Riedemann
    I'm currently writing a small game with box2dweb and I need some direction for this: I'm throwing a Box and have to hit a specific place and trigger an event when the object that's been thrown isn't moving anymore, "fell asleep" so to say. What's the proper way / best practice for this? I'm currently thinking of asking the b2World whether an Object is within a specific AABB and then wait a few seconds, check if it's still there and then trigger the event. But this seems to me like the roundabout way and the object might still be moving inside of that AABB and eventually even drop out of the AABB.

  • Limit the size of a directory by deleting old files

    - by Sulliwane
    I have a IP cam which save its recordings in a specific directory named Camera1 in my Ubuntu Server 12.04. I would like to limit the size of this folder to 5 gigs, by deleting -say once a day- the oldest files. I first checked the quota program but it doesn't seem to allow the creation of new files and deleting of the old ones. So I think the best workaround would be to run a bash script ? But I have no idea how to write it... Thank you guys !

  • Does Agile (scrum) require one server environment?

    - by Matt W
    Is it necessary/recommend/best practice/any other positive to use only one server environment to perform all development, unit testing and QA? If so, is it then wise/part of Agile to then have only one staging environment before Live? Considering that this could mean internationally distributed teams of developers and testers in different time zones is this wise? This is something being implemented by our QA manager. The opinion put forward is that doing all the dev and testing on a single server is "Agile." The staging environment would be a second environment, and then live.

  • Online architecture guide

    - by hunterman
    I am a newbie in gamedev, and I don't know about programmer's problems that can appear during development. So can you advice me some best practice for starting build new online multi-player game backend? I just saw reddraft server, and I think Spring library can also do some of its features. What is big difference? Do I need learn more spring or I have to use servers like reddraft or write these tools myself? I know that I need to learn hard and many - and the question is - what I should to learn now at the beginning? Thanks.

  • Clear Linux file system after shutdown / start

    - by user35443
    I have very specific task. I need to clear the desktop, downloads, documents and so on after every shutdown or finish. For example, if anyone downloads something using Google Chrome, he will work with it and then he'll shutdown the computer for next use. And when second user sits for working on the computer, he'll find a clear file system without the data downloaded by the first user. On Windows, I used to work with Returnil Virtual System, but it doesn't have support for Linux. Can anybody tell me if is it possible and, if so, how? I was also thinking of using Wine for this program, but don't think it will be the best idea.

  • How can I install iTunes in such a way that it can't put any "hooks" or helper programs on my computer?

    - by Joshua Carmody
    I'm buying a new iPad, which means I must once again install iTunes. I've not used iTunes in more than 6 months, since I bought a new computer. I don't like iTunes, but I can live with using it to buy/manage media and sync my Apple devices when the program is open. What I would like to do though, is find a way to install iTunes in such a way that it has absolutely no effect on my system when it is closed. iTunes normally installs several helper programs such as iTunesHelper.exe, and the Bonjour service. These programs run in the background when iTunes is closed. You can force-close them, or remove them from your setup files, but iTunes will often put them right back when you run it. I know these programs are mostly harmless, but they have at times caused issues such as iTunes spending system resources trying to catalog media files or drives connected to VPN, or other issues. At best they're just one more small background process eating up a small piece of my CPU time and RAM. How can I run iTunes without letting it get it's "hooks" into my system? One thought I had is that I could create a Windows user account just for iTunes, and deny it admin privileges. Then if I installed iTunes using that account maybe anything it installed wouldn't affect the "main" account on my PC? But I'm not sure if that would work.... Failing that, maybe some kind of virtualization software or sandbox I could install it in? I'm open to any suggestions. My system is an Intel-based PC running Windows 7 Professional 64-bit. Thanks!

  • Which forum applications can integrate with Facebook? [closed]

    - by deathlock
    EDIT: I don't think this is a duplicate... I ask for a specific feature, which is Facebook integration. I know this question existed, but I need something more specific than that. That one doesn't outline what I need. What is the best/most compatible forum software which features almost complete integration with Facebook? The main feature I ask is the Facebook Connect feature (user could use Facebook account to register). But it would be more perfect if other Facebook features could be integrated to. Something like, subscribe thread which appears to Facebook notifications, easy sharing to Facebook, etc. I have vBulletin, Invision Power Board, and SMF in my mind, but I'm open to more suggestions..

  • Is there a way to emulate pinch-zoom?

    - by aking1012
    I'm looking for a way to emulate pinch zoom in either an android emulator(android SDK-less desirable) or a (preferred) native Ubuntu web browser that I can resize to a specified size for initial testing of HTML5 applications. This is would be useful for first round testing during cross-platform application development. Note: I'm trying to do this with no real touch-device only a mouse. So the best answer would be something like "Install this chromium plug-in and use this hotkey to set pinch points" or something similar. We already have this for getting dual mouse working(thanks AmithKK). The browser that supports multi-touch is the hard part. Something to note is that I start getting screen artifacts using multiple mice via that guide. They're mild and tolerable, but they are there.

    I'm currently developing a website where users will be able to upload content. I would like to be able to show a full-page ad whenever someone tries to view the content. The ad should take up most of the screen, and I should be able to have a "continue to the content --" link at the top. Preferably, I want something like what is currently on Forbes (if you haven't seen it, here: http://www.forbes.com/fdc/welcome.shtml but with an ad in the black area). Of course, the most revenue is the best. Thanks.

  • Path Finding for an Arena based map in 3D using NavMesh

    - by Happybirthday
    I have a 3D arena map (consider a small island surrounded by water on all sides) for a multiplayer Tank fight game. The moveable areas are marked using a Navigation Mesh made by the Arena designer. My question is what would be the best way for navigation in such an environment ? Specially considering the case when there is a Bridge at the center of the arena and you could walk under it or even above it ? If suppose the enemy is standing at the top of the Bridge and my AI is at one of the edges of the map ? How can it know whether the enemy is above or below the bridge and how can it navigate till it ?

  • When designing a job queue, what should determine the scope of a job?

    - by Stuart Pegg
    We've got a job queue system that'll cheerfully process any kind of job given to it. We intend to use it to process jobs that each contain 2 tasks: Job (Pass information from one server to another) Fetch task (get the data, slowly) Send task (send the data, comparatively quickly) The difficulty we're having is that we don't know whether to break the tasks into separate jobs, or process the job in one go. Are there any best practices or useful references on this subject? Is there some obvious benefit to a method that we're missing? So far we can see these benefits for each method: Split Job lease length reflects job length: Rather than total of two Finer granularity on recovery: If we lose outgoing connectivity we can tell them all to retry The starting state of the second task is saved to job history: Helps with debugging (although similar logging could be added in single task method) Single Single job to be scheduled: Less processing overhead Data not stale on recovery: If the outgoing downtime is quite long, the pending Send jobs could be outdated
