  • Problem mounting USB Mobile Broadband dongle in Ubuntu 13.04

    - by Still A Learner
    I have been using Ubuntu 13.04 since last two months and I have problem mounting my USB dongle. I have Lenovo G-580 series laptop. It has 3 USB ports which are 3.0. When I attach dongle to one of the three USB ports the device gets mounted immediately but in the other two ports I have to reboot the OS while the dongle is attached to the laptop in order to mount it and connect to the internet. My dongle is of ZTE. I don't get what is going wrong.

  • How To Get Browser To Open From Same Folder?

    - by Bad Learner
    I don't know how to make the title any more clear. Let me give an example - When I want to add an image to an article on my blog, I click "Browse" button in the image uploader, and then upload the image to the blog. The problem is, when I want to upload another image to my blog, I want the browser to look into the same directory; but it's always takes me to the "Recently Used" directory. Is there a way to change this? I hope I have made myself clear enough. EDIT: I only use Chrome, so I am referring to it.

  • Is "Interface inheritance" always safe?

    - by Software Engeneering Learner
    I'm reading "Effective Java" by Josh Bloch and in there is Item 16 where he tells how to use inheritance in a correct way and by inheritance he means only class inheritance, not implementing interfaces or extend interfaces by other interfaces. I didn't find any mention of interface inheritance in the entire book. Does this mean that interface inheritance is always safe? Or there are guidlines for interface inheritance?

  • Why does Java allow to implement different interfaces, each containing a method with the same signature?

    - by Software Engeneering Learner
    I've recently found that I can have two interfaces containing method with the same signature as a method in the other interface. And then I can have an interface or class that implements both of that interfaces. So the descendant class/interface has implicitly implements two different methods as a one method. Why is this allowed in Java? I can see a numerous problems that arises from that. Even eclipse only can find out about implementations for only one interface method, but for the second one it doesn't show any implementations at all. Also I believe there would be problems with automatic refactoring, like when you would like to change the signature of the method in one of the interfaces and IDE won't be able to correctly change that signature in all implementations, as they implement two different interfaces and how will IDE know what interface method it implementation descends. Why don't just make a compiler error like 'interfaces method names clashes' or something like that?

  • Is it ok to become junior at 27? [closed]

    - by Dvole
    I'm having a computer unrelated job right now, but I want to become a programmer, I have some objective-c and iOS knowledge, studying hard in my free time, etc. I'm looking into getting a junior iOS developer position. It will probably pay half what I earn in my current job, and I am not sure if I will like that. But I am really tired of my job and want to get experience in this field. Also, working as iOS developer is great position, since they are in great demand. My country is Russia. What do you think? Or Should I just do it in my free time, get some programs out in Appstore and look for better position? What would you do?

  • Community Day at SOS Kinderdorf Bambous

    Easter is not only an occassion of public holidays but an opportunity to share and celebrate with your neighborhood. The team of IOS Indian Ocean Software Ltd. spent Easter Monday with the children and "mothers" of SOS Children's Village in Bambous. Together with the employees' family members we enjoyed some wonderful hours together. Starting the community day with a common lunch, IOS contributed mainly stationery, educational gifts and games like Scrabble or Sudoku. And of course, a little give-away with chocolate eggs... The kids are aged between 5 and 18 years. They live together with their village mothers in so-called family houses. The SOS Kinderdorf in Bambous is quite new and started their operations back in 2003, with an official inauguration in May 2005. Actually, I'm really happy about this event and I am looking forward to IOS next community activity. Community off-line and for real people, not only virtual!   PS: Article in L'Express of 09.04.2010

  • How to install Chrome browser properly via command line?

    - by Bad Learner
    Setting up and managing an Ubuntu server all by myself, in coming months, is a part of my current plans. Hence, I am planning a swtich from Windows to Linux - - Ubuntu. I now need to get some grip on the command line, since I am all used to Windows' GUI. Anyway... the most obvious start is installing apps on my computer, and I thought I should learn to do it via CLI. And this is what I did: $ apt-cache search chrome browser the results showed that the proper term is "chrome-browser," so... $ sudo apt-get install chrome-browser And then "Y" for the Y/n question. But the installation threw errors. (I do not have my PC at hand, so can't mention what error exactly.) Does someone see anything wrong with the commands I issued? I am probably missing some command(s) in between, I think.

  • About insertion sort and especially why it's said that copy is much faster than swap?

    - by Software Engeneering Learner
    From Lafore's "Data Structures and Algorithms in Java": (about insertion sort (which uses copy + shift instead of swap (used in bubble and selection sort))) However, a copy isn’t as time-consuming as a swap, so for random data this algo- rithm runs twice as fast as the bubble sort and faster than the selectionsort. Also author doesn't mention how time consuming shift is. From my POV copy is the simplest pointer assignment operation. While swap is 3x pointer assignment operations. Which doesn't take much time. Also shift of N elemtns is Nx pointer assignment operations. Please correct me if I'm wrong. Please explain, why what author says is true? I don't understand.

  • Help me understand a part of Java Language Specification

    - by Software Engeneering Learner
    I'm reading part 17.2.1 of Java language specification: http://docs.oracle.com/javase/specs/jls/se7/html/jls-17.html#jls-17.2.1 I won't copy a text, it's too long, but I would like to know, why for third step of sequence they're saying that If thread t was removed from m's wait set in step 2 due to an interrupt Thread couldn't get to step 2 it wasn't removed from wait set, because it written for the step 1: Thread t does not execute any further instructions until it has been removed from m's wait set Thus thread can't be removed from wait set in step 2 whatever it's due to, because it was already removed. Please help me understand this.

  • solve a partition misalignment?

    - by learner
    I have a new Dell XPS laptop which had Windows 7 installed in it. It also had a default extra partition for "Dell Utility". I installed Ubuntu in it on an Extended Partition along with windows and specified the logical partitions myself (for /,/home and swap). Now when I open Disk Utility , it shows this "Partition misaligned by 512 bytes" error for the Dell Utility partition and "Partition misaligned by 1024 bytes" for the entire Extended partition where Ubuntu is installed. Deleting the extended partition and re-installing Ubuntu may solve the problem of misalignment in the extended partition. But how about the Dell Utility partition? If I re-install Windows 7 Dell Utility wouldn't be a part of the re-install. So that may not solve it either. How do I fix this? Note: The extended partition I made contains an NTFS logical partition for holding data accessible by both OSes(basically a personal data partition). EDIT: I deleted all my Ubuntu partitions and re-installed Ubuntu like before,this time making them partitions with GParted via LiveCD. Now the only problem is that there is a misalignment in the Dell Utility partition. The other misalignment got fixed. Now how do I get rid of that issue?

But apparently it didn't rightly install the drivers and now I have Unity 2D running!

  • How are you coping with Ubuntu's Unity app launcher? (It auto-hides, can't minimize apps)

    - by Bad Learner
    [Firstly, let me tell you that this cannot be subjective in anyway, as I think at least Ubuntu beginners will have these questions boggling in their mind; and yes, this is a question that has a definite answer - - so, I am completely within the rules.] Okay, coming to the point, I see that Ubuntu uses Unity since v10.xx (netbook edition?) and carried the same to v11.04 & v11.10. As someone who's stuck to Windows for all these years, it's somewhat difficult to cope with Ubuntu's Unity, for the following reasons: [1] The Unity app launcher (to the screen's left) auto-hides when a window is maximized. [2]- And once launched, apps cannot be minimized by clicking the app's icon in the launcher. I have to go to the top-left of the screen and click the "_" button. I do know I can fix these issues by installing some configuration tool. But the thing is, if that's how it's meant to work, Canonical/Ubuntu would have designed it that way. But they didn't. Why? w.r.t above points [1], [2]: [1] EDITED: So, does it mean, it's good to work without maximizing the windows? Because if I maximize the window, the app launcher hides. And I need to hover the mouse to the left of the screen, wait a bit (even if it's a sec or even less, I can still feel the lag), and then click on the next app icon in the launcher to switch to it. I do know, I can use Alt+TAB to switch, but I am not sure which window comes next. This, I feel, isn't productive. Also, this makes me feel, Ubuntu is designed for large screens (it's nice on my 1920x1080p screen), because I can have two windows side-by-side or something like that on a large screen. This is not possible on smaller screens. [2]- Being able to minimize an application's window by clicking on its icon in the launcher (just like it works on Windows & probably elsewhere) would have been great, rather than having to go to the top-left and clicking the _ (minimize) button which brings up the app launcher itself (from hiding) most of the time. It's too tiring to have these small issues in the UI. I really would like to know how you are coping with these issues the way they are?

  • 6 Great Alternative Browsers for Your Android Device

    - by Chris Hoffman
    Android’s default browser, named “Internet,” is a very simple browser that’s tied to your Android OS version. Other, third-party browsers offer more powerful interfaces, greater configurability, and more frequent updates. Unlike on Apple’s iOS, Android browsers can implement their own rendering engines, although not all do. That Firefox app isn’t just a shell over the stock browser, like it is on iOS – it brings Mozilla’s Gecko to Android.

  • Display turns off when watching videos (then video starts to lag), how to fix it?

    - by Bad Learner
    Okay, here's the thing - - On my Ubuntu 11.10 64-bit installation, I have the display set to turn off automatically after 3 minutes of inactivity. There are two problems now: the display turns off even when I am watching videos. But I don't want to keep fiddling my mouse or keyboard when I am watching a movie. Okay, like I said above, the display turns off, then I move the mouse a bit each time, and the display turns back on. But now, the video doesn't play properly, it lags. A lot actually. Are these issues common? Can these be fixed?

  • Releasing Mobile Application under multiple platforms, same time or?

    - by SAFAD
    I've always had this idea circling around until I am facing this issue. We made an android app, it is ready, but we are planning to release the same app on iOS and possibly Windows Phone; Now, should we just release the Android app and promise the clients that the iOS version is coming soon (create anticipation before release) or delay the release until the iOS version is ready ? Same applies if we have a premium and free version, should we release the free version and promise that the better premium is coming soon, or release them both the same time ? Best Regards

  • What is the difference between "data hiding" and "encapsulation"?

    - by Software Engeneering Learner
    I'm reading "Java concurrency in practice" and there is said: "Fortunately, the same object-oriented techniques that help you write well-organized, maintainable classes - such as encapsulation and data hiding -can also help you create thread-safe classes." The problem #1 - I never heard about data hiding and don't know what it is. The problem #2 - I always thought that encapsulation is using private vs public, and is actually the data hiding. Can you please explain what data hiding is and how it differs from encapsulation?

  • I'm looking for websites with programming problems that I can practice [on hold]

    - by Spentak
    I want to become a more skilled programmer. I also want to do it through Objective-C and iOS. What websites or programs that you know of have problems that I can solve (with the answers)? I have failed some programming tests for jobs (such as "Given 2 values in a Binary Tree - how do you find the lowest common ancestor?) and I want to become a better engineer. I have developed 54 iOS/Android apps to date, but my core CS Skills apparently are rusty/bad. I have looked at TopCoder - but there aren't very many competitions going on, the website is terrible, and there does not appear to be anything that really supports Objective-C/iOS Websites?

  • Is there any complications or side effects for changing final field access/visibility modifier from private to protected?

    - by Software Engeneering Learner
    I have a private final field in one class and then I want to address that field in a subclass. I want to change field access/visibility modifier from private to protected, so I don't have to call getField() method from subclass and I can instead address that field directly (which is more clear and cohessive). Will there be any side effects or complications if I change private to protected for a final field? UPDATE: from logical point of view, it's obvious that descendant should be able to directly access all predecessor fields, right? But there are certain constraints that are imposed on private final fields by JVM, like 100% initialization guarantee after construction phase(useful for concurrency) and so on. So I would like to know, by changing from private to protected, won't that or any other constraints be compromised?

  • Connection make b/w iphone to windows pc-rajay [on hold]

    - by Rajay
    I Need to create connection between ios to windows by using socket programming in ios. I'm trying to to use an application to communicate with Windows via sockets. At the minimum, I'm trying to at least figure out how I can create a connection from the iPhone (maybe using the iPhone to ping the Windows machine?) I'm not really clear on where I need to start. I'm pretty new to iOS development in general, and brand new to socket/network programming. I've tried several tutorials that haven't gotten me far. My goal is: Connect to a server via sockets (the server will be a Windows machine with a service waiting for incoming connections from the iPhone) If possible, I would like to write/build the client piece first, but I have been lost thus far. Hopefully the nice folks in the SO community can lend a hand and point me in the right direction.

  • I'm writing a diagnostic app for iOS that loads a predetermined set of webpages and records the time it takes for the page to render on the device.

    - by user1754840
    I'm writing a sort of diagnostic app for iOS that opens a predetermined list of websites and records the elapsed time it takes each to load. I have the app open a UIWebView within a ViewController. Here are the important bits of the ViewController source: - (void)viewDidLoad { [super viewDidLoad]; DataClass *obj = [DataClass getInstance]; obj.startOfTest = [NSDate date]; //load the first webpage NSString *urlString = [websites objectAtIndex:obj.counter]; //assume firstWebsite is already instantiated and counter is initially set to zero obj.counter = obj.counter + 1; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [obj.websiteStartTimes addObject:[NSDate date]]; [webView loadRequest:request]; } - (void)webViewDidFinishLoading:(UIWebView *)localWebView{ DataClass *obj = [DataClass getInstance]; //gets 'global' variables if(!webView.loading){ NSString *urlString = [websites objectAt:obj.counter]; obj.counter = obj.counter + 1; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [obj.websiteStartTimes addObject:[NSDate date]]; [webView loadRequest:request]; } The problem with this code is that it seems to load the next website before the one before it has finished. I would have thought that both the call to webViewDidFinishLoading AND the if statement within that would ensure that the website would be done, but that's not the case. I've noticed that sometimes, a single website will invoke the didFinishLoading method more than once, but it would only enter the if statement once. For example, if I have a list of ten websites, the webView would only really show the 3rd and the 6th website on the list and then indicate that it was "done" rendering them all. What else can I do to ensure that a website is done loading completely and rendered to the screen before the app moves on to the next one?

  • OTA plist app install from within phonegap app for iPad

    - by Farhan Ahmad
    I am trying to initiate a OTA app install from within a phonegap iPad app. I have tried this: var url = "http://www.example.com/test.plist"; window.open("itms-services://?action=download-manifest&url=" + url, "_blank"); This works in iOS 5 but NOT iOS 6. I have also tried using the ChildBrowser plugin to point to a page with a link to the OTA app install but that doesn't work either. (If I visit the webpage directly from within the native iPad browser, it works fine) Does anyone know how I can initiate a OTA app install from within the phonegap iPad app? (must work in iOS 5 and iOS 6) I am trying to implement an auto update feature within a Ad-Hock iPad app (not through App Store). So when the app detects that there is a new update, it will prompt the user to install the new update and thats where I need this functionality.

  • Android-iPhone single codebase cross development

    - by Lorenzo
    Is there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android? The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C. What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS? Update: based on current answers, the best cross platform development tool for iOS and Android seems to be Titanium appcelerator. I suspect that this topic will evolve overtime, so feel free to contribute with new information and comments. Thank you!
