  • Battery life low on notebook using ubuntu 11.10 vs. windows 7

    - by les
    Im using a brand new Dell XPS notebook (bought mar 2012) which has 4.5 hrs battery life using a 6 cell battery-when i use windows 7. The machine uses an Intel core 17 2670qm processor, and a 64 bit operating system. I downloaded Ubuntu 11.10 and installed it on a USB drive, which is how i use it. I still have Windows 7 on the machine. When the machine is booting up I hit F12, and run Ubuntu from the flash drive instead of the machine booting Windows, as it normally would. On the Ubuntu menu, on the top right area, there is a battery menu, which shows how long to charge battery, or how much life left etc..with a fully charged battery the most Ubuntu will give me is 1.5 hrs. I've adjusted all power setting etc by clicking on the battery meter where i can make these adjustments, and have even turned down the brightness on the monitor. I've read through these questions here, and a user wrote to install Ubuntu 12(?)(the alpha version) when it's out this month(april), and this has better power management. Other forums (Ubuntu wiki) state that windows 7 controls power management effectively because it's configured to work with the hardware. I'd like to install Ubuntu and wipe windows but can't because of this issue. I need my notebook to go hours, not an hour and a bit. Can anybody recommend possibly a good software to use, that will work with the machines bios under Ubuntu? Another thought of mine, is- since I didn't yet wipe windows off my hard disk, is windows still possibly controlling the power mgmt aspect on the machine? I've thought of calling tech support at Dell and asking for help there, maybe Dell has something (a tweak?), I can download that'll work under Ubuntu. Looking forward to any help/suggestions i can get here, i'm really stuck on this..

  • Working for a company vs starting my own? [closed]

    - by Mark
    I need some advice, I am considering going to grad school for CS. I have a few big projects I came up with on my own that I am extremely motivated to work on and complete and try to turn it into a career. I am currently completing an internship working for a big company, decent pay, 9-5 hours in an office. I feel like working for the same company many people would enjoy and like, is extremely boring in my opinion and procedural at times and kills my motivation. As a result, I am kind of unsure if I should continue to get my CS M.S. degree and start working for a big company? What I would enjoy doing most is working for myself and developing my own project, but I am not sure if I will be able to finanically support myself doing that and I do not want to miss out on a big opportuinities/ job offers to work for a company. With that being said, I will never know if my project will ever succeed if I don't give it %110 of my time and dedication, so if I decide to go that route and work on my own project, I will have to set everything else aside, If anyone could give me any advice on what they think about my situation?

  • Is there a way to detect non-movement (touch events) ?

    - by hyn
    Is there a way to detect a finger's non-movement by using a combination of UITouch events? The event methods touchesEnded and touchesCancelled are only fired when the event is cancelled or the finger lifted. I would like to know when a touch has stopped moving, even while it is still touching the screen.

  • How do you render a rails partial that is outside of a namespace in a view that is inside of a namespace?

    - by iand675
    I've got a 'static' controller and static views that are pages that don't utilize ruby in their views. For these pages, I have a sitemap partial that is generated programatically and used in the application layout file. Namespaced routes still use the application layout file but are taking the static routes and trying to namespace them too. Here's the relevant portion of the route file: namespace :admin do resources :verse_categories resources :verses resources :songs resources :flowers resources :visits, :except => [:new, :create] end match ':action' => 'static' root :to => 'static#home' Here's the error I'm getting: No route matches {:controller=>"admin/static", :action=>"about"} Note that about is one of the static pages that the sitemap partial uses. So, how can I resolve this routing issue so that it's not trying to find my static sites inside of the admin namespace? Any help would be appreciated!

  • What are the pros and cons of public sector vs private sector software development? [closed]

    - by j.i.h.
    I'm currently considering a job working for my state of residence. However, besides the obvious drawback of far less compensation than I could get in the private sector, are there any other drawbacks? Are there any upsides to public work, besides helping society at large and benefits? My main concern is that if I work in the public sector, I might be stained with the perception that I "got along" in an uncompetitive environment. I have no idea if this would be the actual environment, but it seems to be the preconception about government work--unionized workers who are simply there because the union keeps them from being fired. So, does anyone have experience working for the government? Do you have experiences working with people transitioning from public to private sector?

  • Where do you earn more money (Autonomous Systems vs Distributed Systems)? [closed]

    - by Puckl
    I am interested in both topics and I can choose between them for my computer science master. I think the distributed systems master focuses more on software technologies and the autononmous systems master is focused on robotics and machine learning. Do you get good jobs in the fild of machine learning without a Ph.D.? I guess there are more jobs available in the Software-Tech world, is this right? Where do you earn more money? (It is not the only criteria, but it matters)

  • Java Definitions

    - by Brian
    I just had a test on java and we had to give the definition of 1) Static: 2) IOExcepion: What I said for static was...a static method is used to define a method as a class method. And I got it wrong so I asked my teacher and he said he wants the actually definition of static not a static method, class or variable just static. Can someone tell me the definition of this and for IOException please Thanks.

  • Is it appropriate to use non-ASCII (natural-language) XML tags?

    - by Vladimir Alexiev
    Is it appropriate to use XML tags (element names) written in non-ASCII natural languages? The XML spec allows it (see Names and Exceptions), but I couldn't find any best practices about this at W3C and related pages. What I'm looking for is practical advice regarding which tools support this, whether important XML-related technologies such as XSLT and XForms may have problems with it, etc.

  • C++: Why does gcc prefer non-const over const when accessing operator[]?

    - by JonasW
    This question might be more appropriately asked regarding C++ in general, but as I am using gcc on linux that's the context. Consider the following program: #include <iostream> #include <map> #include <string> using namespace std; template <typename TKey, typename TValue> class Dictionary{ public: map<TKey, TValue> internal; TValue & operator[](TKey const & key) { cout << "operator[] with key " << key << " called " << endl; return internal[key]; } TValue const & operator[](TKey const & key) const { cout << "operator[] const with key " << key << " called " << endl; return internal.at(key); } }; int main(int argc, char* argv[]) { Dictionary<string, string> dict; dict["1"] = "one"; cout << "first one: " << dict["1"] << endl; return 0; } When executing the program, the output is: operator[] with key 1 called operator[] with key 1 called first one: one What I would like is to have the compiler choose the operator[]const method instead in the second call. The reason is that without having used dict["1"] before, the call to operator[] causes the internal map to create the data that does not exist, even if the only thing I wanted was to do some debugging output, which of course is a fatal application error. The behaviour I am looking for would be something like the C# index operator which has a get and a set operation and where you could throw an exception if the getter tries to access something that doesn't exist: class MyDictionary<TKey, TVal> { private Dictionary<TKey, TVal> dict = new Dictionary<TKey, TVal>(); public TVal this[TKey idx] { get { if(!dict.ContainsKey(idx)) throw KeyNotFoundException("..."); return dict[idx]; } set { dict[idx] = value; } } } Thus, I wonder why the gcc prefers the non-const call over the const call when non-const access is not required.

  • How do I make non-framework code to framework code? (PHP)

    - by ggfan
    I just started using CakePHP and it's very different from just normal procedural or basic OOP PHP. I am still learning PHP and still read "beginning PHP/mysql" books that teaches you basic PHP. Also lots of sites online provide code that isn't for a framework. Is the only way to make non-framework code to say a framework, say cakePHP, by learning cakePHP thoroughly than rewriting the code yourself to fit the MVC model?

  • What are the design principles that promote testable code? (designing testable code vs driving design through tests)

    - by bot
    Most of the projects that I work on consider development and unit testing in isolation which makes writing unit tests at a later instance a nightmare. My objective is to keep testing in mind during the high level and low level design phases itself. I want to know if there are any well defined design principles that promote testable code. One such principle that I have come to understand recently is Dependency Inversion through Dependency injection and Inversion of Control. I have read that there is something known as SOLID. I want to understand if following the SOLID principles indirectly results in code that is easily testable? If not, are there any well-defined design principles that promote testable code? I am aware that there is something known as Test Driven Development. Although, I am more interested in designing code with testing in mind during the design phase itself rather than driving design through tests. I hope this makes sense. One more question related to this topic is whether it's alright to re-factor an existing product/project and make changes to code and design for the purpose of being able to write a unit test case for each module?

  • Regular expression to match non-negative integers in PHP?

    - by kavoir.com
    I seem to get it to work with the following regexp by preg_match(): @^(?:[1-9][0-9]*)|0$@ Yet it's weird that it matches '-0', considering there are no '-' allowed at all in the regexp. Why? What's more weird is that if you switch the parts divided by |: @^0|(?:[1-9][0-9]*)$@ It matches all negative integers such as '-2' and '-10', etc. What am I missing here? Any better regexp for non-negative integer?
