  • Google Chromecast cast tab from Chrome browser sucks

    - by Ken Hortsch
    Originally posted on: http://geekswithblogs.net/BlueProbe/archive/2013/07/28/153537.aspxOk so I know it’s in beta.  And I should have known when I watched the Nexus 7 and Chromecast press event and the demo showed the browser casting a slide show.  But, when I bought one of these little $35 beauties and tried casting a soccer game from ESPN it was pathetic with a 2 FPS rate.  Netflix and YouTube are awesome.  We’ll see what we get out of beta.

  • xubuntu app menu on wrong side of screen

    - by D0X
    I am using Xubuntu 12.04, with a dual monitor setup (with the nvidia driver xinerama enabled). The top panel is spanned acros the two monitors. This works quite fine, except for one thing. When I click the little Application Menu button on my left screen, the application menu opens on the top right corner of the left screen. This is quite annoying, I fiddled in the panel prefs but could not fix this. Any thoughts?

  • How do I transition from physics and math to programming?

    - by inovaovao
    I'm a physics PhD with little actual programming experience. I've always liked programming and played around with BASIC, Pascal as a teen, but the extent of my experience writing complex programs comes from an introductory course in computer science. Now I've decided that I'm more interested in programming than in physics and started to learn Java. Coming from a physics or math-heavy background, what would be the best strategy to maximize my value in the field?

  • Why can't `main` return a double or String rather than int or void?

    - by sunny
    In many languages such as C, C++, and Java, the main method/function has a return type of void or int, but not double or String. What might be the reasons behind that? I know a little bit that we can't do that because main is called by runtime library and it expects some syntax like int main() or int main(int,char**) so we have to stick to that. So my question is: why does main have the type signature that it has, and not a different one?

  • Netbook Review: MSI Wind12 U230

    You probably think $480 is a little steep for a netbook, and it is -- for one that doesn't have dual-core horsepower, a full-sized keyboard, and a 12- instead of 10-inch screen. We test MSI's netbook for people who don't like netbooks.

  • Code Design question, circular reference across classes?

    - by dsollen
    I have no code here, as this is more of a design question (I assume this is still the best place to ask it). I have a very simple server in java which stores a mapping between certain values and UUID which are to be used by many systems across multiple platforms. It accepts a connection from a client and creates a clientSocket which stores the socket and all the other relevant data unique to that connection. Each clientSocket will run in their own thread and will block on the socket waiting for a read. I expect very little strain on this system, it will rarely get called, but when it does get a call it will need to respond quickly and due to the risk of it having a peak time with multiple calls coming in at once threaded is still better. Each thread has a reference to a Mapper class which stores the mapping of UUID which it's reporting to others (with proper synchronization of course). This all works until I have to add a new UUID to the list. When this happens I want to report to all clients that care about that particular UUID that a new one was added. I can't multicast (limitation of the system I'm running on) so I'm having each socket send the message to the client through the established socket. However, since each thread only knows about the socket it's waiting on I didn't have a clear method of looking up every thread/socket that cares about the data to inform them of the new UUID. Polling is out mostly because it seems a little too convoluted to try to maintain a list of newly added UUID. My solution as of now is to have the 'parent' class which creates the mapper class and spawns all the threads pass itself as an argument to the mapper. Then when the mapper creates a new UUID it can make a call to the parent class telling it to send out updates to all the other sockets that care about the change. I'm concerned that this may be a bad design due to the use of a circular reference; parent has a reference to mapper (to pass it to new ClientSocket threads) and mapper points to parent. It doesn't really feel like a bad design to me but I wanted to check since circular references are suppose to be bad. Note: I realize this means that the thread associated with whatever socket originally received the request that spawned the creation of a UUID is going to pay the 'cost' of outputting to all the other clients that care about the new UUID. I don't care about this; as I said I suspect the client to receive only intermittent messages. It's unlikely for one socket to receive multiple messages at one time, and there won't be that many sockets so it shouldn't take too long to send messages to each of them. Perhaps later I'll fix the fact that I'm saddling higher work load on whatever unfortunate thread gets the first request; but for now I think it's fine.

  • Collaborative coding chat options

    - by jayunit100
    Hi guys : Are there any established online sites for collaborative coding ? I have a github project with 5 developers, in different areas - we need somewhere that we can all "hangout" at. Right now we use group skype, but skype is designed more for family/social communication , and doesn't work on linux. IRC is okay, but its a little difficult to use for novices. an interface like yammer, twitter, facebook would be ideal, but also, we would want it to be real time (not requiring page reloads etc...)

  • Custom wallpapers under "Appearance" are dissapearing [12.04]

    - by user73449
    When I add wallpapers via the little "+" under "Appearance Look" in the settings, I can select them and it works fine. But when I reopen the Appearance setting and want to change my wallpaper, the custom ones are gone. Why is this? Below is a screenshot of the empty custom wallpaper section. Unfortunately I don't know what this is called in English, so I have a hard time searching for my problem. http://i.stack.imgur.com/eyytG.png

    - by user866190
    Why keep this question open and others like it open which basically asks how long does it take to learn a programming language? Yet I ask a valid question which basically asks how esteemed is a mathematics degree from the UK open university and would software employers hire whilst you are the course.. and it gets closed I love the advice I get from this site and I appreciate the fact that Software Technicians of all types use this site, but it's a bit shallow if you can't ask a question with a little bit of the real world involved

  • Gerrit code review, or Github's fork and pull model?

    - by user1366476
    I am starting a software project that will be team AND community developed. I was previously sold on gerrit, but now github's fork and pull request model seem to almost provide more tools, ways to visualize commits, and ease of use. For someone who has at least a little experience with both, what are the pros/cons of each, and which would be better for a team based project which wants to leave open the possibility for community development?

  • xfce4 - 'Run Program' dialogue box does not appear when double clicking script

    - by Ron Paulfan
    Ubuntu 12.04 Xfce4 On my previous Ubuntu distro, when I double clicked scripts I got a little dialogue window that asked me if I wanted to run the script as a program or run it in terminal. Similar to this window: Since upgrading, I have never seen that window. I have ensured that the option to 'Allow executing as a program is enabled' and the script works if I run it through terminal. I simply just don't get the prompt. Any ideas?

  • What are pros and cons of native checkout for an ecommerce app (mobile)?

    Looking at some of the ecommerce apps, I am guessing that some use native checkout process, and some use webviews.
