• How to prepare for an online job interview (maybe through Skype)?

  - by phunehehe

  I'm applying for a company far away and if I get an interview it will probably be done remotely. I have been searching for advices regarding this but all tips seem to be directed at face-to-face meetings (things like "shake hands firmly"). What are the differences? How can I make the best out of those differences? Update: This is a software developer position, so there's also something about technical questions (such as, I can Google anything that they ask ;) This question also applies to any freelancers who are dealing with customers, or recruiters who are interviewing remotely. I hope that makes it relevant to this site. It may also help if you keep answers programers-related.

• 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?

• 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.

• 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)

• 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?

• 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 ongoing work in the kernel team to improve battery life under linux?

  - by leousa

  I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

• Is there a formal name for gradually initiating 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?

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

• 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.

• 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.

• In a team practicing Domain Driven Design, should the whole team participate in Stakeholder meetings?

  - by thirdy

  In my experience, a Software Development Team that comprises: 1 Project Manager 1 Tech Lead 1 - 2 Senior Dev 2 - 3 Junior Dev (Fresh grad) Only the Tech Lead & PM (and/or Senor Dev/s) will participate in a meeting with Clients, Domain Experts, Client's technical resource. I can think of the ff potential pitfalls: Important info gets lost Human error (TL/PM might forgot to disseminate info due to pressure or plain human error) Non-verbal info (maybe a presentation using a diagram presented by Domain Expert) Maintaining Ubiquitous language is harder to build since not all team members get to hear the non-dev persons Potential of creative minds are not fully realized (Personally, I am more motivated to think/explore when I am involved with these important meetings) Advantages of this approach: Only one point of contact Less time spent on meetings? Honestly, I am biased & against this approach. I would like to hear your opinions. Is this how you do it in your team? Thanks in advance!
