• Mobile Web Framework that will only control rendering and page transitions

  - by rlemon

  I have been using jQueryMobile for a bit now, and there are some things I like about it and others I do not. First I will give a bit of background. I have a light weight mobile application that has a few configurations and 6 pages. Ideally I Would like to load all pages into the DOM (they interact with each other quite often and pages will be switched in the same frequency). The application will post for some JSON every n seconds and refresh the values on the page (yes it is primarily a information display app). with the jQuery Mobile framework the only real thing I like is how easy it is to have a standardized UI a crossed all devices and browsers, I'm really not using too much else out of the framework other than the basic page navigation (if you are familiar with the framework; a bare-bone multi-page design is all i need). Why I want to step away from jQueryMobile is how weighty it is. Not only do you need to include the mobile library, but also the base jQuery libraries. This I do not like because I'm not using jQuery anywhere else on the site. Any suggestions on light-weight mobile frameworks that have a similar rendering as jQueryMobile?

• A fix for the design time error in MVVM Light V4.1

  - by Laurent Bugnion

  For those of you who installed V4.1 of MVVM Light and created a project for Windows Phone 8, you will have noticed an error showing up in the design surface (either in Visual Studio designer, or in Expression Blend). The error says: “Could not load type ‘System.ComponentModel.INotifyPropertyChanging’ from assembly ‘mscorlib.extensions’” with additional information about version numbers. The error is caused by an incompatibility between versions of System.Windows.Interactivity. Because this assembly is strongly named, any version incompatibility is causing the kind of error shown here (for an interesting discussion on the strong naming issue, see this thread on Codeplex). I managed to resolve the issue for Windows Phone 8 and will publish a cleaned up installer next week. In the mean time, in order to allow you to continue development, please follow the steps: Download the new DLLs zip package (MVVMLight_V4_1_25_WP8). Right click on the Zip file and select Properties from the context menu. Press the “Unblock” button (if available) and then OK. Right click again on the zip package and select “Extract all…”. Select a known location for the new DLLs. Open the MVVM Light project with the design time error in Visual Studio 2012. Open the References folder in the Solution Explorer. Select the following DLLs: GalaSoft.MvvmLight.dll, GalaSoft.MvvmLight.Extras.dll, Microsoft.Practices.ServiceLocation.dll and System.Windows.Interactivity.dll. Press “delete” and confirm to remove the DLLs from your project. Right click on References and select Add Reference from the context menu. Browse to the folder with the new DLLs. Select the four new DLLs and press OK. Rebuild your application, and open it again in Blend or in the Visual Studio designer. The error should be gone now. In the next few days, as time allows, I will publish a new MSI containing a fixed version of the DLLs as well as a few other improvements. This quick fix should however allow you to continue working on your Windows Phone 8 projects in design mode too.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Switching mdadm to an external bitmap

  - by Oli

  I've just read this in another post about improving RAID5/6 write speeds: After increasing stripe cache & switching to external bitmap, my speeds are 160 Mb/s writes, 260 Mb/s reads. :-D I've already found out how to increase the stripe cache and this worked pretty well but I'd like to know more about an external bitmap. I have an incredibly fast (540MB/s) RAID0 SSD that would do well if a bitmap does what I think it does but I'm still very unsure. I've only known about them as long as I've known this post. A few questions: What is a bitmap (in terms of mdadm)? What are the advantages of an internal bitmap (over external)? What are the advantages of an external bitmap (over internal)? How do I switch between the two? I should add that while this is a I'm-bored-let's-break-something thread, I do value the data stored on the RAID array. If doing this is going to put data at significant risk, please let me know.

• Do your own design jobs and make it look professional

  - by Webgui

  Looks and design is becoming more and more important for customers and organizations event when we deal with internal enterprise applications. However,  many web developers who work on business apps end up not investing resources on the design. The reason may be that they ran out of time so with their client's pressure there was no choice but to skip past the design process. In some cases, especially in sall software houses, there are no trained professional designers and the developers have to do both jobs. Since designing web applications can be very complex and requires mastering several languages and concepts, unless a big budget was allocated to the project it is very hard to produce a professional custom design. For that exact reasons, Visual WebGui integrated Point & Click Design Tools within its Web/Cloud Development Platform. Those tools allow developers to customize the UI look of the applications they build in a visual way that is fairly simple and doesn't require coding or mastering HTML, CSS and JavaScript in order to design. The development tools also allow professional designers easier work interface with the developers and quicly create new skins. So if you are interested in getting your design job done much easier, you should probably tune in for about an hour and find out how.

• Which architecture should I choose for this project?

  - by Jichao

  I have a project. The server which based on a phone PCI-board is responsible for received phone calls from the customer and then redirect the phone calls to the operators. I have decided to code the server using c++ programming language and qt framework because the PCI-board SDK's interface is c/c++ originated and for the sake of portability. The server need to send the information of the the customer to the operator while ringing the operator and the ui interface of the operator client should be browser-based. Now the key problem is how could the server notify the operator that there is a phone call for he/she. One architecture I have considered is like this, The operator browser client use ajax pooling the web server to check whether there is call to the client; the web server pooling the database server to check whether there is call; the desktop server(c++) wait for the phone calls and set the information in the database. The other operations such as hang up the phone call from the client, retransfer the phone call to the other operator also use this architecture. Then, is there any way other than pooling the server(js code setInterval('getDail', 1000)) to decide whether there is a call to the operator? Is this architecture feasible or should I use some terrific techniques that I do know such as web services,xml-rpc, soap???

• Lucene best practice

  - by Dragos

  I am trying to understand how Lucene should be used. From what I have read, creating an IndexReader is costly, so using a Search Manager shoulg be the right choice. However, a SearchManager should be produced by a NRTManager(which, by the way, should replace the IndexWriter for every add or delete operation performed). But in order to have a NRTManager, I should first have an IndexWriter, and here comes my problem. The documentation says: an IndexWriter is thread-safe the constructor of this class takes a Directory object, so it seems creating an instace should be costly(as in the case of an IndexReader) all changes are buffered and flushed periodically(so they seem to encourage using a single instance) but: the changes, although flushed will only be visible after commit or close after finished making updates(add/delete), the instance should be closed I also found this: http://stackoverflow.com/questions/5374419/forgot-to-close-the-lucene-indexwriter-after-adding-documents-to-the-index where it is said that not closing a writer might ruin everything So what am I really supposed to do? Is having a single IndexWriter instance a good idea(make only commit and never close it)? EDIT: What is more, if I use NRTManager, how can I make acommit`? Is it even possible?

• What are all the components of a "Facebook App"?

  - by pnongrata

  I am a developer who has never personally partaken in social media (in any form) for reasons completely outside the scope of this question. I am "off the grid" (no Facebook, Twitter, etc accounts). I'm currently building a web app and would like the app to have a presence on Facebook, and possibly even "port" my app over as a Facebook app. My understanding of Facebook Apps is that they're just normal web apps that get <iframe>d into a Facebook page. The app is actually hosted on your server (not FB's servers). But this got me thinking: Don't Facebook Apps have "profile pages"? Is there anything developers can do to customize the behavior of their own profile pages? Do apps have the ability to do things like MySpace themes used to do (i.e., customize and interact with User profile pages, Groups, etc.)? Do Facebook Apps gain any sort of extra capabilities (inside of Facebook) that a normal web app would not have? It seems to me like if all a Facebook App is, is an iframed-web app, that it would still need to communicate with Facebook via its many APIs, just like a normal app would have to, right? If it's not possible to write an app that can customize the UI or behavior of user profiles and other pages, then how do games like "Farmville" interact with User profiles so that you see updates to profiles like "John Smith reached level 2 of Farmville"? Basically, I'm asking any battle-worn Facebook app developers if my understanding of Facebook Apps is correct, or if I'm missing anything big here. It's my understanding that for security reasons (obviously) Facebook doesn't allow apps to customize anything outside of the iframe it lives in. So if I want my app to appear like it's "interacting" with its Facebook users, it looks like I just need to publish stuff to the users' news feeds to try and encourage people to use my app (please correct me if I'm wrong here!). Thanks in advance for any corrections, clarifications, advice or suggestions!

• Non-blocking ORM issues

  - by Nikolay Fominyh

  Once I had question on SO, and found that there are no non-blocking ORMs for my favorite framework. I mean ORM with callback support for asynchronous retrieval. The ORM would be supplied with a callback or some such to "activate" when data has been received. Otherwise ORM needs to be split of in a separate thread to guarantee UI responsiveness. I want to create one, but I have some questions that blocking me from starting development: What issues we can meet when developing ORM? Does word "non-blocking" before word "ORM" will dramatically increase complexity of ORM? Why there are not much non-blocking ORMs around? Update: It looks, that I have to improve my question. We have solutions that already allows us to receive data in non-blocking way. And I believe that not all companies that use such solutions - using raw SQL. We want to create more generic solution, that we can reuse in future projects. What difficulties we can meet?

• Crash due to removal of Elements like CCSprite from NSMutableArray

  - by mayuur

  So, here's how it goes. I am currently working on Cocos2d game, which consists of many Obstacles. One obstacle gets added on the screen at an interval of 10 seconds like this. ObstacleSprite* newObstacle = [ObstacleSprite spriteWithFile:@"Obstacle.png" rect:CGRectMake(0, 0, 20, 20)]; newObstacle.position = ccp(mainPlayer1.position.x,10); [self addChild:newObstacle]; [self.arrayForObstacles addObject:newObstacle]; Now, I insert these obstacles into the arrayForObstacles because I also want to keep checking whether the Obstacles and MainPlayer don't collide. I check it with the help of this function. - (void) checkCollisionWithObstacle { if(mainPlayer1.playerActive) { for(int i = 0; i < [self.arrayForObstacles count]; i++) { ObstacleSprite* newObstacle = [self.arrayForObstacles objectAtIndex:i]; if(newObstacle != nil) { if(CGRectIntersectsRect([mainPlayer1 boundingBox], [newObstacle boundingBox])) { mainPlayer1.livesLeft--; } } } } } THE ISSUE Problem is when I get to certain score, one of the Obstacles gets deleted. Removal of Obstacles works as in First In-First Out (FIFO) mode. So, to delete obstacles, I write the following method : - (void) keepUpdatingScore { //update new score mainPlayer1.score+=10; //remove obstacle when score increases by 5k if(mainPlayer1.score > 5000 && mainPlayer1.score > 0) { mainPlayer1.playerActive = NO; if([self.arrayForObstacles count] > 0) { CCLOG(@"count is %d",[self.arrayForObstacles count]); ObstacleSprite* newObstacle = [self.arrayForObstacles objectAtIndex:0]; [self.arrayForObstacles removeObjectAtIndex:0]; [self removeChild:newObstacle cleanup:YES]; CCLOG(@"count is %d",[self.arrayForObstacles count]); } } else { } } It crashes when score crosses 5000 mark! UPDATE Crash happens when it again goes to the method checkCollisionWithObstacle. This is the THREAD Look. THis is the line Which crashes.

• GLES2.0 3D Android game performance and multi threading the update?

  - by Ofer

  I have profiled my mixed Java\C++ Android game and I got the following result: https://dl.dropbox.com/u/8025882/PompiDev/AndroidProfile.png As you can see, the pink think is a C++ functions that updates the game. It does things like updating the logic but it mostly it generates a "request list" for rendering. The thing is, I generate DrawLists on C++ and then send them to Java to process and draw using GLES2.0. Since then I was able to improve update from 9ms down to about 7ms, but I would like to ask if I would benefit from multi threading the update? As I understand from that diagram is that the function that takes the most time is the one you see it's color on the timeline. So the pink area is taken mostly by update. The other area has MainOpenGL.Handle as it's main contributor(whch is my java function), but since it's not drawn to the top of the diagram I can conclude other things are happening at the same time that use the CPU? Or even GPU stuff that isn't shown in this diagram. I am not sure how the GPU works on this. Does it calculate stuff in parallel to the CPU? Or is it part of the CPU usage as in SoC? I am not sure. Anyway, in case GPU things DO happen in parallel to CPU, then I would guess that if I do this C++ Update in parallel to the thread that makes the OpenGL calls, I might make use of "dead CPU time" due to GPU stalling or maybe have the GPU calls getting processed earlier because it won't have to wait for Update to finish? How do you suggest to improve performance based on that? Thanks.

• Ubuntu installed along side Win 8 but not shown in boot

  - by Mahesha999

  Actually the question says it all, but let me tell you what I did, so u may find exactly what might have went wrong: I have Win 8 installed on 500 GB HDD. SO I shrunk it four times for: partition 1 - the original partition containing Win 8 sys (118GB) partition 2 - NTFS formatted for my data (188GB) partition 3 - NTFS formatted for my data (100GB) partition 4 - NTFS formatted for Linux distro 1 (I reformatted it to ext4 during Ubuntu installation) (25GB) partition 5 - NTFS formatted for Linux distro 1 (21GB) So now I booted Ubuntu from USB (created from ubuntu-12.04-desktop-amd64.iso) and deleted last two partitions 4 and 5 to create: partition 1 - ext4 where I installed Ubuntu (25GB) partition 2 - Swap (4GB) partition 3 - unallocated space, not formatted yet (17GB) Ubuntu installation said it installed successfully and that I have to restart to boot in Ubuntu. But when I restart Windows 8 auto booted - there was no dual boot. After that I devided above 100GB partition to 80Gb and 20GB ones (since I read online that I should have /home in separate partition for convenience, so I created 20GB partition for it) So I went on to manually create boot entry using EasyBCD as below show in picture at below link http://s19.postimage.org/dof2zuvw3/Free_BCD.png When I created the entry, FreeBCD showed the information as follows: Windows Boot Manager -------------------- identifier {9dea862c-5cdd-4e70-acc1-f32b344d4795} device partition=\Device\HarddiskVolume2 description Windows Boot Manager locale en-US inherit {7ea2e1ac-2e61-4728-aaa3-896d9d0a9f0e} integrityservices Enable default {ea8167ad-d189-11e1-90e4-ab2f09569dcc} resumeobject {ea8167a3-d189-11e1-90e4-ab2f09569dcc} displayorder {ea8167ad-d189-11e1-90e4-ab2f09569dcc} {ea8167b1-d189-11e1-90e4-ab2f09569dcc} toolsdisplayorder {b2721d73-1db4-4c62-bf78-c548a880142d} timeout 10 displaybootmenu Yes Windows Boot Loader ------------------- identifier {ea8167ad-d189-11e1-90e4-ab2f09569dcc} device partition=C: path \Windows\system32\winload.exe description Windows 8 locale en-US osdevice partition=C: systemroot \Windows resumeobject {9bc7fdf7-3ae0-11e2-be77-806e6f6e6963} Real-mode Boot Sector --------------------- identifier {ea8167b1-d189-11e1-90e4-ab2f09569dcc} device partition=C: path \NST\AutoNeoGrub0.mbr description Ubuntu Notice the last bolded entry created.

• Software center is not working after attempt to install skype

  I am completely new person on Linux. I installed it just today and i have to say I like them a lot, until I faced the problem. I was looking on the internet but nothing worked for me. After i downloaded skype and tried to run it, software center showed up and was loading something for 5 mins. then it just dessapeared. Now everytime I try to turn it on, the window is gone after 3 sec. I tried to kill it but didnt really wokrked.

• Is there really anything to gain with complex design? [duplicate]

  - by SB2055

  This question already has an answer here: What is enterprise software, exactly? 8 answers I've been working for a consulting firm for some time, with clients of various sizes, and I've seen web applications ranging in complexity from really simple: MVC Service Layer EF DB To really complex: MVC UoW DI / IoC Repository Service UI Tests Unit Tests Integration Tests But on both ends of the spectrum, the quality requirements are about the same. In simple projects, new devs / consultants can hop on, make changes, and contribute immediately, without having to wade through 6 layers of abstraction to understand what's going on, or risking misunderstanding some complex abstraction and costing down the line. In all cases, there was never a need to actually make code swappable or reusable - and the tests were never actually maintained past the first iteration because requirements changed, it was too time-consuming, deadlines, business pressure, etc etc. So if - in the end - testing and interfaces aren't used rapid development (read: cost-savings) is a priority the project's requirements will be changing a lot while in development ...would it be wrong to recommend a super-simple architecture, even to solve a complex problem, for an enterprise client? Is it complexity that defines enterprise solutions, or is it the reliability, # concurrent users, ease-of-maintenance, or all of the above? I know this is a very vague question, and any answer wouldn't apply to all cases, but I'm interested in hearing from devs / consultants that have been in the business for a while and that have worked with these varying degrees of complexity, to hear if the cool-but-expensive abstractions are worth the overall cost, at least while the project is in development.

• Connecting / disconnecting DisplayPort causes crash

  - by iGadget

  I wanted to file a bug about this using ubuntu-bug xserver-xorg-video-intel, but the system prompted my to try posting here first. So here goes :-) While the situation in Ubuntu 11.10 was still somewhat workable (see UI freezes when disconnecting DisplayPort), in 12.04 (using Unity 3D) it has gotten worse. The weird part is that during the 12.04 beta's, the situation was actually improving! I was able to successfully connect and disconnect a DisplayPort monitor without the system breaking down on me. But now with 12.04 final (with all updates), it's just plain terrible. When I now connect an external monitor using the DisplayPort connector on my HP ProBook 6550b, it only works sometimes. Most times (but not always!) the screen just goes blank and the system seems to crash (not even CTRL+ALT+F1 works anymore). Only a hard shutdown by keeping the power button pressed for several seconds and then a restart gets me out of this. I suspect the chances of the system crashing become higher as the system's uptime increases, especially when there have been one or more suspend-resume cycles (although I have also experienced this bug once from a cold boot). Disconnecting is roughly the same as with 11.10 (see issue mentioned above), with the difference that if I resume from suspend, I no longer have to do a CTRL+ALT+F1, ALT+F7 cycle to get my screen back. So what more can I try? Or should I just go ahead and file the bug anyway?

• Ubuntu 11.10 not starting in Graphical mode?

  - by iammilind

  I am in deep trouble. I am using Ubuntu 11.10 in dual boot mode with XP. Originally my touch pad was not working, (sometimes). To fix that, I installed something. After reboot my Ubuntu is not booting up!! I have several software pkgs already installed in past several weeks so reinstall of OS is my last resort. Can someone help me to get it rebooted in graphical mode? I had followed the procedure mentioned in this thread as well. With that link, somehow I am able to restart in text mode. But no luck after that. I am not being able to go back on graphical mode. The important outputs of lspci are following: 00.00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) 00:02.0 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) I am attaching few snapshots, for more details on hardware.

• How do I remove a malformed line from my sources.list?

  - by eminencejae

  I have unistalled and reinstalled the Ubuntu Software Center as per info I found in a similar thread and I got the same response about line 91 or something like that. I just tried to upload a screen shot but since I'm new it won't allow me to. I also can not figure out how to cut and paste anything so I have to hand type what the error screen says, both when I attempt to open the software center and nothing happens, when I try to enter commands into the terminal to uninstall, reinstall, whatever I get the same following: COULD NOT INTITIALIZE THE PACKAGE INFORMATION An unresolvable problem occured while initializing the package information Please report t:his bug against the 'update-manager' package and include the following error message: 'E: Malformed line 91 in source list/etc/apt/sources.list (dist parse) E: The list of sources could not be read., E: The package list of status file could not be parsed or opened. How do I report bugs? What can be done about this. I have searched and everything everyone says to do leads me back to the same line error message. So, I don't know how to get to line 91 in the source list; to tell you what it says. Sorry, I'm really new to this. That is what I need is to find out how to get there and fix what it says. I would really like to NOT have to re partition my hard drive and start from scratch, so I'm really looking forward to getting this problem solved. I need to be able to install new software.

• How to connect ethernet on ubuntu (with auto-detection by Ubuntu)

  - by user12285

  Do I need to post another thread for the same? If so, sorry. Yes, I saw that it's been well over six months but I have the same router SmartAX MT880d with ethernet, and the exact same problem, that is no internet even though I can successfully reach the modem settings page by entering 192.168.1.1 in Firefox. Sorry if I don't use the right (technical) terminology to express my issue. English is not my mother tongue. I'm a total beginner with ubuntu. My internet works great in Windows but does not work in Ubuntu. For 2 weeks, I've kept reading on the web and forums and the ubuntuguide.org to name a few but to no avail. Now I see no other solution but to ask for help. My problem is that as a beginner, I can't find a way to put the right digits in the right place because I don't know what numbers I need to put in what files (eg: do I need to use DHCP? or a static IP address? No clue whatsoever. I'm confused between putting figures in the wrong spaces. For example, is the modem/router's IP exactly 192.168.1.1 for Huawei Smart AXMT880d modem?? Is the subnet 255.255.255.0? Gateway 192.168.1.1. I'm confused as I can also see a different IP starting with 155131*** (is it an account number? no clue again) on my contract with Huawei (a Chinese ISP). Apart from calling 911, what other numbers do I need to put in and where? How do I check that all the numbers have been entered correctly in every appropriate space before trying to connect the Internet?

• How to do a 3-tier using PHP [closed]

  - by Ric

  I have a requirement from a client for my PHP Web application to be 3-tier. For example, I would have a web server on Apache in the DMZ, but it should NOT contain any DB connections. It should connect to a Middle server that would host the business objects but be behind the firewall. Then those objects connect to my SQL cluster on another server. I have actually done this using .NET, but I am not sure how to setup my stack using PHP. I suppose I could have my UI front tier call the middle tier using REST based web services if I create my middle tier as a second web server, but this seems overly complex. The main reason for this is advanced security: we can not have any passwords on the DMZ first tier web server. The second reason is scalability - to have multiple server on different tiers that can handle the requests. The Last reason is for deployment - it is easier if I can take one set of servers offline for testing before putting them back in production. Is there a open source project that shows how to do this? The only example I can find is the web server hosting files from a shared drive on another machine (kind of how DotNetNuke pretends to be 3-tier), but that is NOT secure.

• No monitor output after fresh install of 11.10 64-bit

  - by James

  I have a machine with a Nvidia 8600GT graphics card and a CRT monitor. Previously, I have only used Windows on it, and the graphics card seems to be working correctly in Windows 7. I booted up and installed Ubuntu 11.10 amd64 from the LiveCD and the whole process worked perfectly. When I tried to boot off the hard disk for the first time, the output to the monitor switched off during the splash screen, and this happens consistently. I can ctrl-alt-f2, so I tried an apt-get upgrade, which didn't help; nor did apt-get install nvidia-current. There is nothing that looks relevant in dmesg. Booting with the nomodeset option has no effect. Following the answers in this similar thread, I tried apt-get purge nvidia-173. Both startx and service lightdm start just say the service is already running. Does anyone know how to find out what the problem is? I was wondering if it is just that Ubuntu is trying to use a resolution that the monitor doesn't support, but I can't find out how to change that from the command line.

• All in a Day's Work: Unblocking Multiple Downloaded Files with a Single Command

  - by Sam Abraham

  Files downloaded using Internet Explorer retain Internet Zone permission level and hence are “Blocked” by default on Windows 7 machines. Honestly, while an added overhead for developers; I really appreciate this feature as it provides a good protection layer for casual web users. My workaround is to simply unblock the downloaded zip file (if download was a zip file) which, in turn, unblocks the files stored within. Today however, I was left with a situation where I had to “Open” and “Copy” the content rather than “Save” a zip file. That of course left me with a few dozen files I have to manually unblock. A few minutes of internet search lead me to the link below which worked like a charm: 1-Download streams.exe from SystInternals - http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx 2-Go to command prompt (cmd.exe) 3-Navigate to where you have streams.exe installed 4-Use command line switches: streams.exe –s –d “<folder path>” This removed the Internet Zone restrictions from all files under “<folder path>” and its subfolders as well. [Deleted :Zone.Identifier:$DATA] References: http://social.technet.microsoft.com/Forums/en-US/itproxpsp/thread/806f0104-1caa-4a66-b504-7a681d1ccb33/

How to put the right type of automated tests in to the right automated builds.Speaker: Eric LandesTwitter: @ericlandesBlog: http://ericlandes.com/ This was one of the first sessions I attended during CodeStock 2012. Eric’s talk focused mostly on unit testing, and that the lack of proper unit testing can be compared to stealing from an employer. His point was that if you’re not doing proper unit testing then all of the time wasted on fixing issues that could have been detected with unit tests is like stealing money from employer. He makes the assumption that that time spent on fixing these issues could have been better spent developing new features that drive the business. To a point I can agree with Eric’s argument regarding unit testing and stealing from a company’s perspective. I can see how he relates resources being shifted from new development to bug fixes as stealing based on the fact that the resources used to fix bugs are directly taken from other projects. He also states that Boring/Redundant and Build/Test tasks should be automated because it reduces the changes of errors and frees up developer to do what they do best, DEVELOP! When he refers to testing, he breaks testing down in to four distinct types. Unit Test Acceptance Test (This also includes Integration Tests) Performance Test UI Test With this he also recommends that developers should not go buck wild striving for 100% code coverage because some test my not provide a great return on investment. In his experience he recommends that 70% test coverage was a very acceptable rate.

• User Switching in XFCE 12.04 with LightDM and dumping unneeccesary Gnome libs

  - by user111120

  I'm an elder non-techie Mac-to-Linux convert trying to play the linux tech game by ear, so please be gentle! :) I am running XFCE Ubuntu 12.04 totally on a 8-gig flash drive and it's fantastic. I am starting to run into potential space issues (down to 1.0 gig free from 1.9 gigs since being installed last summer), most likely because of growing Thunderbird mail files, and this prompted my question. I just installed lightDM on my system because I want the ability to switch users in XFCE if I follow instructions on another blog. They advised using LightDM instead of GDM because LightDM doesn't download Gnome libraries. That's great since I need the space, but my question is how can I tell whether I don't already have Gnome libraries installed from other updates and such? And can I minimize having any Gnome libraries? The method for me to switch users entails creating a "fast-user-switch" file in /usr/local/bin; is there any easier way? One last thing so I din't have topen another needless thread; while experimenting I somehow lost the share folder in one of my accounts. Is there any way to get a share folder back? Thanks for any tips! Jim in NYC

• How do you track existing requirements over time?

  - by CaptainAwesomePants

  I'm a software engineer working on a complex, ongoing website. It has a lot of moving parts and a small team of UI designers and business folks adding new features and tweaking old ones. Over the last year or so, we've added hundreds of interesting little edge cases. Planning, implementing, and testing them is not a problem. The problem comes later, when we want to refactor or add another new feature. Nobody remembers half of the old features and edge cases from a year ago. When we want to add a new change, we notice that code does all sorts of things in there, and we're not entirely sure which things are intentional requirements and which are meaningless side effects. Did someone last year request that the login token was supposed to only be valid for 30 minutes, or did some programmers just pick a sensible default? Can we change it? Back when the product was first envisioned, we created some documentation describing how the site worked. Since then we created a few additional documents describing new features, but nobody ever goes back and updates those documents when new features are requested, so the only authoritative documentation is the code itself. But the code provides no justification, no reason for its actions: only the how, never the why. What do other long-running teams do to keep track of what the requirements were and why?

• O'reilly certification in PHP worth it?

  - by editzombie

  I asked this question over on stack overflow but I didn't realise it wasn't really the place for not so technical questions. I've seen quite a few related threads on this forum so I thought I'd try and get some feedback here: This is my first time asking a question on this forum, though I´ve read it a lot. I apologise if this is repeating a thread. I´m interested in getting into web development. I am a video editor by trade but living in Spain the way things are at the moment its very difficult to find work. I have some very basic knowledge of HTML and CSS and a little bit of flash and have designed a few little personal websites myself. I also worked for a online marketing production company where I worked a little on blog design in Blogger amongst other social media. So thats my background, but I´m trying to expand my skills and get into web development as a career or in general part of my skill base, I was thinking particularly about PHP/MySQL. I have worked a little on some of the Lynda.com tutorials and have invested in a book (Sams Teach Yourself PHP, MySQL and Apache). I´m still finding it very difficult to progress. I know I should really try some practice projects (any reccomendations would be welcome). But I was also thinking about doing one of the O´Reilly certification courses and was wondering whether it would be worthwhile for a noob like me. I hear that the courses are associated with an American University which I guess gives it more clout. Any other thoughts you guys have about how to make progress in learning web development would be fantasic. Thanks in advance.

• What exactly is bootstrap admin-template and how it is supposed to be used

  - by Leron

  So this is my second ASP.NET MVC 4 project. It's decided that for this one we will use this template and it was said in a way that I felt really stupid for not knowing how exactly this template will help us and what exactly we gain by using it. I'm used to using HTML/CSS for the UI combined with jQuery. Now it seems that instead of jQuery we will be using bootstrap which as far as I understand is just another JS library created from twitter, so if that's it then this part is clear. What I really need to clarify for myself is what exactly this theme is used for, what is offering, why one would want to use such a theme? From what I see in the live demo maybe it's just a stack of premade controls that you can use in the front end along with bootstrap.js and maybe I'm just confused because on the page is shown as much as possible just for presentational purposes. If that's right, still I wonder where I can find info for the current theme, the controls that it offers and the functionality that I get and not least - how to use it. But still those are just my assumptions. What I really need is a clarification on what exactly is this theme for, what is the advantage using it, is there a good tutorials about how to use such themes in the context of ASP.NET MVC 3+. Also any additional info about this theme and generally on using themes in ASP.NET MVC will be much appreciated.
