• Trying to learn ASP.net

  - by sipl

  Hi There, I have a background in computers and had done programming some seven years ago. Switched to becoming a technical writer (oops!). And now think I should jump ship again, back to being a programmer. Of course the natural course of action where I can spend say two whole years learning to code, might not be available any more. I am keen on ASP.net as its the language that most products at my company are written in. I am sure this has been asked before, but here I go... where do I begin? Would really appreciate some practical advise. Thanks, SA

• From Editor-in-Chief to Reader (part two)

  - by alexismp

  It's time for me (Alexis) to move to new challenges and this 773rd post of mine on TheAquarium will be my last one. For all these years since TheAquarium was started by others, this place has seen the community come to life, grow and thrive. It has been an effective way for the GlassFish team to share our progress and for you the community to provide feedback, both good and not so good. Thank you for your continued readership, support and feedback, all of which contributed to keep TheAquarium the #1 technical blog at Oracle and helped us improve Java EE and GlassFish in a significant way. Oracle has exciting and ambitious plans for GlassFish 4.0 and Java EE 7 and I trust TheAquarium will remain an important link in the chain as both of these are being delivered. I leave you in the hands of savvy and sharp contributors. Long live The Aquarium! - AlexisMP

• Adding PPA on install

  - by trampster

  I have a app I am packaging for ubuntu. I don't like the idea that if included in the ubuntu repositories I will have no control over updating that application. I don't want my users stuck on an out dated version for up to 6 months. I also do not want my users to have to manually add a PPA themselves to get updates as the target user will not have the technical know how to do this. Is it OK to have my .deb add a PPA on install. So that I can roll out stable updates to my ubuntu users.

• How can I improve the workflow between developer and designer with Expression Blend?

  - by Amenti

  We use WPF and Expression Blend 4. I'm trying to improve our workflow by tutoring one of our designers to use it for styling and animation. Slowly but surely I get the impression Blend in itself is to technical for the designer in question. I myself use it only occasionally (it's great for Visual States for instance) because a lot of things are easier done in code or not possible at all in Blend alone. It seems a developer with design experience is a lot more productive with it than a sole designer. Are there any good resources or advice as to how I can improve this workflow?

• Is there any way to get faster app reviews?

  - by David

  I am trying to build a business around an iPhone app. The app will be our main sales channel, and being able to adapt the sales channel faster than the 9-10 days delay cause by the app review times is crucial. Therefore, I was wondering whether there is anything I can do to improve the speed of reviews. I am thinking that the publishers of Angry Birds, surely would not have to wait in line for reviews on the same terms as some obscure free app. So what can I do? Some things I am considering: Would Apple prioritize apps that they earn money on? Could I in some way pay Apple directly? I already know of the possibility of requesting an expedite review, but it seems like one can get punished for supplying a non-technical reason.

• Issue with wired network

  - by Shiju Nambiar

  I have ubuntu 12.10 (downgraded from 13.04 when I faced this issue). I am a newbee and don't know much of technical side like commandline on the terminal. I have a wired internet connection and it was working just fine for last few months since I installed ubuntu. my OS got upgraded to 13.04 and it was still fine. Since last 3 days, network shows connected, connection stays for few seconds and then websites stop loading. Connection shows as connected, but pages don't load. I have to reconnect again to access a website and the connection goes off again in say about 10 to 15 seconds. So I use my internet by connecting and disconnecting every few seconds.

• How do you write straight to the point documentation without looking sloppy and informal?

  - by James

  I'm currently at a contract position and am looking to add to the documentation of the projects I worked on, to assist the next hiree taking over my projects. The documentation I received was overly technical (i.e. references code right away, references replacing certain values on certain lines, no high level description at all) How do I write documentation in simple plain English that is of actual benefit without looking sloppy? I find it difficult in areas such as outlining a system's flaws without coming off as judgmental, but still emphasize the severity of how detrimental some of the flaws are.

• How to enable home directory encryption for a particular user?

  - by Ivan

  I prefer to have a dedicated "administrator" user for technical purposes and that was one I've set up during installation. I've also refused to encrypt the home folder of the user. Now, as I've added a user account for my actual work usage I want my (but not the "administrator") home folder to be encrypted. How to turn this on? If it is not possible then how to enable encryption for all users home directories on a system already installed? I've found questions and answers about how to disable it but am not sure how to enable it.

• How to reinstall Windows 8 after accidentally wiping it off my HDD

  - by user286538

  So about half an hour ago I decided to try out Ubuntu and in the process of doing so, my hard drive got wiped. My Windows 8 installation, and all the files with it are gone. Since my laptop came preinstalled with Windows 8, I don't have a disk or anything to use to install it again. I guess I'll have to install all of my things again, but first, I just want to know how to get Windows 8 back(will the serial number on the bottom of my laptop work?) so I can get back to an OS I'm familiar with. Any explanations would be great. Please don't be too technical though.

• How Do You Test Your Software ?

  - by Kubi

  I'm currently working on 2 software projects: A Social Networking Web Site for an NGO A Patient Management System for a hospital Although I've been programming for 5 years, I can't just say that I'm very good at testing or Test Driven Designing an application. How would you arrange your Software Testing before coding phase, during coding and after you finished the coding phase for a. providing stakeholders with information about the quality of the product or service under test. b. providing an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. and how do you understand that your program/application/product c. meets the business and technical requirements that guided its design and development d. works as expected p.s. please feel free to edit the question since my english is not very powerful.

• Can someone explain why Chromium is difficult to build for Ubuntu?

  - by vasa1

  I hope this question is not regarded as a duplicate of Does someone know why the Chromium daily package isn't build anymore? because that question relates to daily builds and not to "stable" Chromium available from the Software Center. So what are the technical difficulties that the Chromium team is facing? A very similar question has been asked in Default Browser Follow-up. I would very much to have an updated Chromium stable on my system. Also, is the problem of building Chromium restricted to 32-bit versions? (I have a 64-bit CPU but just 4 GB RAM and so I'm staying with 32-bit all the way.) I'm asking this partly in the light of the discussions, here for example, about having Chromium as the default web browser in future releases.

• Is there a formal name for gradually activating software changes?

  - by g .

  At times when we develop new features or functionality, we gradually "turn it on" to ensure a smooth transition and minimal impact for users. Instead of one big sudden change, we are able to control with the configuration aspects of the functionality that make it more or less intrusive to the user. This is all done in the same release/version of the software, so no software development changes are required (unless bugs turn up that need to be fixed). For example, initially we may only perform logging or analysis of data without acting upon it. Or we make something optional for a period of time before it becomes compulsory. The idea is that this reduces the potential for problems either on the technical side as well as unexpected changes by the user. The question is, is there a formal name for this approach?

• Using "Google Guava" in coding interviews

  - by kbgn27

  I attended a in-person interview recently and performed well. But surprisingly I got rejected. When I asked the HR for reason, he contacted the technical interviewer and told me that I was syntactically wrong while coding. I used Google Guava for coding. So my code looked like this: List<String> items = Lists.newArrayList() instead of List<String> items =new ArrayList<String>(); I know that the code will compile and work as expected.Is it ok to use third party libraries like Google Guava in interviews?

• Identifying connected lines drawn free-hand by a user

  - by rawrgoesthelion

  I have a series of 'images' described by a mixture of connected lines and curves. Users will draw on the screen, free hand, and my goal is to break their drawing down into a series of lines and curves that can be matched with the 'images' in my set. For the sake of simplicity, let's assume this is occurring on a touch screen. These lines will be connected. Each time the user's finger moves, the dx and dy is recorded. The drawing is considered complete and analyzed when the user's finger leaves the screen. I'm having trouble figuring out a good way to break the user's drawing down into lines. Is there any well known approach to this problem, a C++ library that solves it, or any good articles/technical papers on how to achieve this?

• Help me come up with my new job title

  - by Seva Alekseyev

  Hi all, I used to be a technical lead in a group of 3-5 programmers. Tech lead's responsibilities here would include thinking of/designing overall solution architecture, coding, refactoring, being the first to dive into the next big thing, reviewing others' code, sitting on customer meetings and answering endless questions from the rest of the team. Now I'm moving on to a branch-level position (in a branch of ~60 people), which entails pretty much the same, sans maybe the coding/refactoring part. Still kinda a tech lead, but the title "tech lead" is already being used and means something else - a group-level tech lead. Please help me come up with a good job title. I need something for my e-mail signature and, eventually, resume.

• Validation and Verification explanation (Boehm) - I cannot understand its point

  - by user970696

  Hopefully my last thread about V&V as I found the B.Boehm is text which I just do not understand well (likely my technical English is not that good). http://csse.usc.edu/csse/TECHRPTS/1979/usccse79-501/usccse79-501.pdf Basically he says that verification is about checking that products derived from requirements baseline must correspond to it and that deviation leads only to changes in these derived products (design, code). But he says it begins with design and ends with acceptance tests (you can check the V model inside). The thing is, I have accepted ISO12207 in terms of all testing is validation, yet it does not make any sense here. In order to be sure the product complies with requirements (acceptance test) I need to test it. Also it says that validation problems means that requirements are bad and needs to be changed - which does not happen with testing that testers do, who just checks correspondence with requirements.

• What is the Ubuntu equivalent of the Windows programs Belarc or PC Wizard?

  - by CeltaWeb

  I provide technical support for several high schools in Spain and I have been building up a inventory of the schools machines. On the windows only computers I normally run PC Wizard to quickly get a good overview of the machines hardware, software and network settings. Is there an equivalent tool preferable with a GUI and an export option to html or pdf in Ubuntu. I have tried a few options such as: Gnomes gconf-editor hardinfo (GUI) lshw (CLI) I'm just looking for an all in one application that builds a detailed profile of the installed software, hardware and network setting of a particular machine. I have found Sysinfo which is quite good, it displays the most important hardware info and allows you to save it to a text file with a neat GUI. I'm still looking for a more complete solution but it's a good start.

• Do unused vertices in a 3D object affect performance?

  - by Gajet

  For my game I need to generate a mesh dynamically. Now I'm wondering does it have a noticeable affect in FPS if I allocate more vertices than what I'm actually using or not? and does it matter if I'm using DirectX or OpenGL? Edit Final output will be a w*h cell grid, but for technical issues it's much easier for me to allocate (w+1)*(h+1) vertices. Sure I'll only use w*h vertices in indexing, and I know there is some memory wasting there, but I want to know if it also affect FPS or not? (Note that mesh is only generated once in each time you play the game)
