• How to get sharing options to stick - ubuntu 12.04

  - by Devin

  I'm having a really hard time trying to get my sharing set up on my 12.04 system. I've tried both desktop version and server - I'm a bit of a linux n00b, so I need a GUI, command line is beyond me and no time to learn it (not till after I get the shares setup, at least) My problem is, whenever I try to set permissions in Nautilus, it just reverts back to the default which is to "none" Basically when I choose an option... it doesn't stick. I can create shares, and it asks me if I want to add permissions automatically - but they do not stick either. When I go to look at the shared folders in Windows (or even on my Android Phone, or Mac) it gives me permissions errors and doesn't let me log in, despite me clicking "allow guest access" I have no idea what to do or where to go. I've tried searching forums and google, and I've tried everything I come across - no avail. I've even tried Mint builds to see if it's different, no change there either. Please help! I really want to setup a server to share my media files and do backups in my house. Thanks for your help!

• How do I mount my Android phone?

  I'm puzzled because my phone used to just appear when I plugged it in. It doesn't anymore and The development options are definitely set to allow USB debugging.

It seems odd that it isn't even appearing in lsusb Not for nothing, the thumb drive on my keyring also does not appear in lsusb -- I've tried both in a bunch of different ports. I kind of assume the thumb drive is just borked, but it could be my OS.

• The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

  - by Hunter2

  Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

• nautilus crash when merging/overwriting files

  - by sBlatt

  On my Ubuntu 10.10, whenever I want to copy some files/folders over some other files/folders, or when I try to empty the trash, nautilus crashes! Example: I have a folder with some files. Now I want to overwrite this folder with a folder with the same name, same files, but some additional files, the merge window comes up, I choose merge and nautilus crashes (does not respond, when I press the close button I can force close it). Some times it even does the copying/emptying (trash), but it always crashes! This happens when copying to the same partition/ntfs partition/netshares, but not when I make a new folder and copy the files/folders into that (without overwriting anything). On a netshare, it's even possible to merge these files afterwards with another computer! dmesg/syslog/messages does not show any entry related to that problem. Does anyone have a solution for this very annoying problem? EDIT: dpkg -l nautilus* (see output in pastebin) EDIT2: I found out, nautilus already crashes before clicking replace/merge (as soon as the question appeares. In the video it's not entirely clear, that i click the cross before the force-close dialog appeares. Video of problem nautilus-debug-log.txt EDIT3: Filed bugreport: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/678233

• Printer share keeps asking for password and I can't authenticate from any machine. Why?

  - by tenshimsm

  Ubuntu 12.04 printer share keeps asking for password and I can't authenticate from any machine. Why?? We've installed it in two machine (to act as printer servers) and we get the same problem. It doesn't matter what we do, change or install. We can't figure out why the printer share asks for password even using all of the users that are registered in the server. What is wrong with Precise? I want it to work without a password, but it is not even working WITH one! I gave up! The samba version that comes with Precise is insufferable! I tried various settings that didn't work. I should've used Mint from the beginning. [Edit] My printers config. Remembering that samba is 3.6.3 in ubuntu 12.04 load printers = yes [printers] comment = All Printers browseable = yes path = /var/spool/samba printable = yes guest ok = yes readonly = yes create mask = 0700 [print$] comment = Printer Drivers path = /var/lib/samba/printers browseable = yes readonly = yes guest ok = yes

• Web migration of a VB6 system with VWG

  - by Webgui

  Brinks Bolivia eSAC System (Customer Service) allows to register all different kinds of contacts for a customer; addition to maintaining an updated status of each service or customer request, to have accurate information and perform the appropriate procedures for all applications. The system was originally developed in VB6 and since web access was essential it was offered via Citrix. Since the application's performance was a critical issue as well as the need to offer the system without specific installations the company looked for a solution that would solve those drawbacks of using Citrix. Searching for a solution that would allow it to offer the eSAC system over the web without the need for specific client installations and provide sufficient performance levels even when there is limited bandwidth lead Brinks to a decision to migrate their VB6 Customer Service system to to Visual WebGui. "Developing on Visual WebGui we were able to migrate the system to web environment and even add new features in less time which allows us to offer it over a standard web browser with better performance and no installations as was required with Citrix," concluded Alexander Cuellar. The full article and screenshots of the system are available here.

• Why is purchasing Microsoft licences such a daunting task? [closed]

  - by John Nevermore

  I've spent 2 frustrating days jumping through hoops and browsing through different local e-shops for VS (Visual Studio) 2010 Pro. And WHS (Windows Home Server) FPP 2011 licenses. I found jack .. - or to be more precise, the closest I found in my country was WHS OEM 2011 licenses after multiple emails sent to individuals found on Microsoft partners page. Question being, why is it so difficult to get your hands on Microsoft licenses as an individual? Sure, you can get the latest end user operating systems from most shops, but when it comes to development tools or server software you are left dry. And companies that do sell licenses most of the time don't even put up pricing or a self service environment for buying the licenses, you need to have an hawk's eye for that shiny little Microsoft partner logo and spam through bunch of emails not knowing, if you can count on them to get the license or not. Sure, i could whip out my credit card and buy the VS 2010 license on the online Microsoft Shop. Well whippideegoddamndoo, they sell that, but they don't sell WHS 11 licenses. Why does a company make it so hard to buy their products? Let's not even talk about the licensing itself being a pain.

• How to debug suspend?

  - by mlissner

  I've been using Ubuntu for about five years now, and I still can't make it suspend when I want to. It's quite irritating that I can program up a storm, hack the machine in numerous other ways, and yet, and yet when I try to make it suspend or debug suspend, I fail miserably. I need help. Where do I begin to find the problem? What do I do to fix it? I'm placing a bounty on this, because I've literally lost hours of my life to this problem, and leaving my computer on ALL the time is terrible. The symptoms: Pressing suspend brings my computer to a state where it has a blinking cursor, the fans are running, it seems that the HD has turned off (I think), and I can't do anything to bring it back from this state (short of a hard reboot). Possibly related: My fans stay on even after a shutdown, and even then, I have to press the power button for five seconds before I can start it up again. I don't know what logs to look at to debug the problem, and I imagine they'd get nuked on reboot anyway. Please, please help. This drives me completely nuts, and I've been living with it for over a year.

• Empty interface to combine multiple interfaces

  - by user1109519

  Suppose you have two interfaces: interface Readable { public void read(); } interface Writable { public void write(); } In some cases the implementing objects can only support one of these but in a lot of cases the implementations will support both interfaces. The people who use the interfaces will have to do something like: // can't write to it without explicit casting Readable myObject = new MyObject(); // can't read from it without explicit casting Writable myObject = new MyObject(); // tight coupling to actual implementation MyObject myObject = new MyObject(); None of these options is terribly convenient, even more so when considering that you want this as a method parameter. One solution would be to declare a wrapping interface: interface TheWholeShabam extends Readable, Writable {} But this has one specific problem: all implementations that support both Readable and Writable have to implement TheWholeShabam if they want to be compatible with people using the interface. Even though it offers nothing apart from the guaranteed presence of both interfaces. Is there a clean solution to this problem or should I go for the wrapper interface? UPDATE It is in fact often necessary to have an object that is both readable and writable so simply seperating the concerns in the arguments is not always a clean solution. UPDATE2 (extracted as answer so it's easier to comment on) UPDATE3 Please beware that the primary usecase for this is not streams (although they too must be supported). Streams make a very specific distinction between input and output and there is a clear separation of responsibilities. Rather, think of something like a bytebuffer where you need one object you can write to and read from, one object that has a very specific state attached to it. These objects exist because they are very useful for some things like asynchronous I/O, encodings,...

• Designing business objects, and gui actions

  - by fozz

  Developing a product ordering system using Java SE 6. The previous implementations used combo boxes, text fields, and check boxes. Preforming validation on action events from the GUI. The validation includes limiting existing combo boxes items, or even availability. The issue in the old system was that the action was received and all rules were applied to the entire business object. This resulted in a huge event change as options were changed multiple times. To be honest I have no idea how an infinite loop wasn't produced. Through the next iteration I stepped in and attempted to limit the chaos by controlling the order in which the selections could be made. Making configuration of BO's a top down approach. I implemented custom box models, action events, beans/binding, and an MVC pattern. However I still am unable to fully isolate action even chains. I'm thinking that I've approached the whole concept backwards in an attempt to stay closest to what was already in place. So the question becomes what do I design instead? I'm currently considering an implementation of Interfaces, Beans, Property Change Listeners to manage the back and forth. Other thoughts were validation exceptions, dynamic proxies.... I'm sure there are a ton of different ways. To say that one way is right is crazy, and I'm sure it will take a blending of multiple patterns. My knowledge of swing/awt validation is limited, previously I did backend logic only. Other considerations are were some sort of binding(jgoodies or otherwise) to directly bind GUI state to BO's.

• Leveraging Code Across Platforms in Ever Bigger Games

  - by ashes999

  Summary: The same way that I continually build complex engines and libraries within a single platform and technology to allow me to build increasingly bigger and better games, how to continue this when development crosses into different platforms? If I switch platforms, how do I leverage past code and experiences? Games are hard to build. Big games are even harder to build. I've decided that to be able to make big games, I need to start building smaller games, and building up an asset base of code, assets (graphics, sounds), tools, and most importantly, game engines, so that I can eventually get there. One game at a time. Let me give an analogy. To build an MMO 3D RPG, I would approach this by building and releasing small games with increasingly more features. This could entail, for example: A simple 2D game A tile-based game A game with RPG elements (items, equipment, monsters, battle) A full-fledged RPG A 3D RPG The problem now is if I have to change platforms or tools, I don't know how to leverage past code-bases (and experience) to start with a mature product. Right now, I'm writing Silverlight (FlatRedBall) games. Let's say I stick with this for ten years, and then suddenly decide to write a PS6 game, which is in a different programming language entirely. Granted, I have ten years of game-development experience (and correspondingly ten years of professional software development experience from my day job) to back me up. But I would still like some way to transplant that 2D RPG engine into the new programming language, or else leverage it somehow. Is this even possible? What are my options?

• Making Modular, Reusable and Loosely Coupled MVC Components

  - by Dusan

  I am building MVC3 application and need some general guidelines on how to manage complex client side interaction between my components. Here is my definition of one component in general way: Component which has it's own controller, model and view. All of the component's logic is placed inside these three parts and component is sort of "standalone", it contains it's own form, data needed for interaction, updates itself with Ajax and so on. Beside this internal logic and behavior of the component, it needs to be able to "Talk" to the outside world. By this I mean it should provide data and events (sort of) so when this component gets embedded in pages can notify other components which then can update based on the current state and data. I have an idea to use client ViewModel (in java-script) which would hookup all relevant components on page and control interaction between them. This would make components reusable, modular - independent of the context in which they are used. How would you do this, I am a bit stuck as I do not know if this is a good approach and there is a technical possibility to achieve this using java-script/jquery. The confusing part is about update via Ajax, how to ensure that component is properly linked to ViewModel when component is Ajax updated (or even worse removed or dynamically added). Also, how should this ViewModel be constructed and which technicalities to use here and in components to work as synergy??? On the web, I have found the various examples of the similar approach, but they are oversimplified (even for dummies) or over specific and do not provide valuable resource or general solution for this kind of implementation. If you have some serious examples it would be, also, very helpful. Note: My aim is to make interactions between many components on the same page simpler and more robust and elegant.

• 12.04 update crash, now cannot boot

  - by EdW

  Boot now freezes the system at the "Ubuntu purple screen" with the 5 dots under it. I cannot even CTRL-ALT-F1 to get to an alternate console. Have to push reset button on computer to reboot. After the 12.04 update crash, the system would boot, but I had no icons and no launch bar and errors about missing dependencies. CTRL-ALT-F1 and ran apt-get -f install and it appeared to get the missing packages. I followed with a apt-get update; apt-get upgrade. It appeared to install all of the remaining 12.04 update packages. Rebooted to same blank screen - no icons, but got a compiz error. In console I tried "unity --reset" rebooted ... Nothing ... It's dead in the water. Tried to boot into Recovery Mode - black screen - I cannot even CTRL-ALT-Del - have to push reboot button. Fortunately, I have Mint on another partition and I can access the broken 12.04 partition. Ideas? I can back up all of my folders using Mint, but I would hate to have to do a new install.

• 12.04 disabling wireless via dbus does not work

  - by FlabbergastedPickle

  I am using a proprietary rt3652sta driver for my wireless card. It appears as a ra0 device on the 64-bit Ubuntu 12.04. According to the online documentation the following used to work definitely up to 10.04. dbus-send --system --type=method_call --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.DBus.Properties.Set string:org.freedesktop.NetworkManager string:WirelessEnabled variant:boolean:false This however has no effect on the aforesaid wireless card in 12.04. Also, rfkill does not work as it does not even list the wireless button (again, likely due to the wireless driver being proprietary): rfkill list It only lists the hci0 (bluetooth) one and one can block/unblock it accordingly but this has no effect on the wifi. ifup/down also does not work (AFAICT)... And this leaves me with disabling wireless through the network manager applet. However, trying to do so via dbus appears not to work and yet I would like to automate it via a script. Any ideas how I could find out the proper dbus structure for the call? Is this even possible in Ubuntu 12.04?

• which style of member-access is preferable

  - by itwasntpete

  the purpose of oop using classes is to encapsulate members from the outer space. i always read that accessing members should be done by methods. for example: template<typename T> class foo_1 { T state_; public: // following below }; the most common doing that by my professor was to have a get and set method. // variant 1 T const& getState() { return state_; } void setState(T const& v) { state_ = v; } or like this: // variant 2 // in my opinion it is easier to read T const& state() { return state_; } void state(T const& v) { state_ = v; } assume the state_ is a variable, which is checked periodically and there is no need to ensure the value (state) is consistent. Is there any disadvantage of accessing the state by reference? for example: // variant 3 // do it by reference T& state() { return state_; } or even directly, if I declare the variable as public. template<typename T> class foo { public: // variant 4 T state; }; In variant 4 I could even ensure consistence by using c++11 atomic. So my question is, which one should I prefer?, Is there any coding standard which would decline one of these pattern? for some code see here

• Webserver insists on opening "blog1.php" instead of "index.php"

  - by pepoluan

  I'm at my wits' end. I have just ripped out a website and in the process of rebuilding everything. Previously, the 'home page' of the website is a blog, with the address "www.mydomain.com/blog1.php". After exporting everything, I deleted the whole directory, and -- based on request -- immediately create a blog/ directory. The idea is to get the blog back up as soon as possible, and temporarily redirect people accessing www.mydomain.com to the blog. Accessing the blog via http://www.mydomain.com/blog/ works. So I put in an index.php file containing a (temporary) redirect to the blog's address. The problem: The server insists on opening blog1.php instead of index.php. Even after we deleted all the files (including .htaccess). And even putting in a new .htaccess file with the single line of DirectoryIndex index.php doesn't work. The server stubbornly wants blog1.php. Now, the server is actually a webhosting, so I have no actual access to it. I have to do my work via cPanel. Currently, I work around this issue by creating blog1.php; but I really want to know why the server does not revert to opening index.php. Did I perhaps miss some important settings in the byzantine cPanel menu page?

• What stops HTML5 and JS apps to perform as good as native apps?

  - by Amogh Talpallikar

  From what I understand, HTML is a mark-up language, so is the content of XAML, XIB and whatever Android uses and other native UI development frameworks. JavaScript is a programming language used along with it to handle client side scripting which will include things like event handling, client side validations and anything else C#,Java,Objective-C or C++ do in various such frameworks. There are MVC/MVVM patterns available in form frameworks like Sencha's, Angular etc. We have localStorage in form of both sqlite and key-value store as other frameworks have and you have API specification for almost everything that it missing. Whenever a native UI frameworks has to render UI , it has to parse a similar the markup and render the UI. Question break-down What stops from doing the same in HTML and JS itself ? Instead of having a web-control or browser as a layer in between why can't HTML(along with CSS) and JS be made to perform the same way ? Even if there is a layer,so does .net runtime and JVM are in other cases where C++,C are not being used. So Lets take the case of Android, like Dalvik, why Can't Chromium be another option(along with dalvik and NDK) where HTML does what android markup does and JavaScript is used to do what Java does ? So the Question is, Even if current implementations aren't as good, but theoretically is it possible to get HTML5 based applications to work as other native apps specially on mobile ?

• OnTrigger not firing consistently

  - by Lautaro

  I have a Prefab called Player which has a Body and a Sword. The game uses 2 instances of Player, Player1 and Player2. I use Player1 to strike Player2. This is code on the sword. My hope is that Sword of Player1 will log on contct with Body of Player2. It happens but only the first hit and then i have to hit several times before another strike is logged. But when i look at log from OnTriggerStay it looks like the TriggerExit is never detected untill long after the sword is gone. void OnTriggerEnter(Collider other) { //Play sound to confirm collision var sm = ObjectDirectory.soundManager; sm.PlaySoundClip(sm.gui_02); Debug.Log(other.name + " - ENTER" ); } void OnTriggerStay(Collider other) { Debug.Log(other.name + " - collision" ); } void OnTriggerExit(Collider other) { Debug.Log(other.name + " - HAS LEFT" ); } DEBUG LOG: Player2 - ENTER UnityEngine.Debug:Log(Object) SwordControl:OnTriggerEnter(Collider) (at Assets/Scripts/SwordControl.cs:28) Player2 - collision UnityEngine.Debug:Log(Object) SwordControl:OnTriggerStay(Collider) (at Assets/Scripts/SwordControl.cs:34) (The last debug log then repeated hundreds of times long after the sword of player 1 had withdrawn and was in no contact with player 2 ) EDIT: Further tests shows that if i move player1 backwards away form player2 i trigger the OnTriggerExit. Even if the sword is not touching Player2 since after the blow. However even after OnTriggerExit it takes many tries untill i can get another blow registered.

• Using 12.04 installation as a persistent pen drive

  - by Cawas

  Disclaimer: I aim to build a self contained pen drive with my application inside, so no matter about updates. Maybe I'm looking at the wrong linux distribution to do this... Please let me know if you think so. I've tried knoppix and even lubuntu, but they don't come with enough "drivers" for Unity3D to work. Creating a custom live persistent pen drive is a real pain and I'm trying for 1 day without any success. Sure, being able to do it would probably be ideal and occupy the minimum space. Using the installation image on a pen drive, however, is good enough and is really easy to create. We can even do it from any OS, using UNetBootin, LiLi USB Creator or some other methods. Straight forward. Some recommend installing it on a pen drive. But that requires a lot of space and, I believe, it won't behave as good as something meant to be installed on a usb disk, because of memory management. So, there are only a few negative points on using the installation image that I can think of. Question here, is how to remove those drawbacks: Having to press "Try Ubuntu". That's the big one. Couldn't find how. Unable to load everything on memory and keep on running without the pen drive (like this) Unable to remove "Install Ubuntu 12.04 LTS" app. Setting the ISO to use maximum amount of space for the OS will leave pen drive with zero space left and any file saved within it from ubuntu is inaccessible from the outside (when plugin the pen drive and not booting from it). Am I missing something? Can those points be fixed?

• PHP frameworks - should I use them?

  - by 30secondstosam

  First of all let me explain who I am: I am a PHP Developer working for a company developing their CMS which handles online stores, data feeds and other content like blogs. I have been programming for 6 years and 4 of those have been in PHP. (I used to be a C# developer). My question is regarding PHP frameworks. I see so many jobs asking for zend, cakephp and other MVC types of frameworks. However, even as an experienced developer I have never used a PHP framework. Should I start learning? If so where do I even start as there are so many. I am about to re-write so much of my work's CMS and I'm wondering whether I could help myself a lot by using a framework. What do people think? Considering I will be re-writing a lot of the online store stuff... I am experienced in OO and I have used the .NET framework in the past. Thanks in advance for the replies.

• How to understand computer science as a whole?

  - by MrCellophane

  I am a college student in Computer Science, I have been studying CS for a long time. But even till today, I still feel so confused about a lot of things. First of all, I have solid foundation in alg, data structure, and OOP, but I don't have a clear understanding of the whole system of the subject. I studied database, alg, data structure, OOP, network, software engineering, OS, and a lot of courses. I know what they are, but I don't know how to connect them together. Is there a way to have a clear understanding of the architecture of the subject? And is there a way to know what technology is used to do what? For example, in interviews, when people ask me alg, data str, Java, OS or any other specific field, I could answer, but when they ask some other very general about the field, I have no idea. Well, I know my question maybe a little bit confusing, but what my situation is I don't even know how to ask a clear question. I don't know my question, it's totally a mess in my head. Is there a way to make it clear?

• What You Said: How You Organize a Messy Music Collection

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your tips, tricks, and tools, for managing a messy music collection. Now we’re back to share so great reader tips; read on to find ways to tame your mountain of music. Several readers were, despite having tried various techniques over the years, fans of doing things largely the manual way. Aurora900 explains: I spent a weekend sorting everything myself once. Took a while, but now I have folders sorted by artist, and within the artist folders are folders for their albums. With my collection at about 260gb, it can be a daunting task, but it’s well worth it in the end. I don’t have the tagging issue as I make sure anything I have is properly tagged to begin with… If I’m ripping a CD I use Easy CD-DA Extractor, which automatically searches a database on the internet for the tags. If I’m downloading something, if its from a reputable source its going to be properly tagged already.
