• No sound/audio after resuming from sleep

  - by hansvonaachen

  I've made a fresh UEFI install of Ubuntu 13.10 (64 bit) on a Lenovo Ideapad Z510 laptop with Intel i5 4200M processor. Ubuntu is the only OS installed on the computer, secure boot disabled. Everythings works fine (backlight issue fixed after editing rc.local file), the only minor trouble I have is resuming the laptop from "sleep" mode. If I close the lid and then wake the laptop opening it again, there is no audio/sound. I need to restart the computer (not even logging out helps). If I suspend the computer in a graphical way (not closing the lid): gearwheel in top right of the screen -- suspend and wake it up/turning on, audio works with no issues. Ideas how to fix this? Thanks!

• What do Embedded Software Developers do on a day to day basis?

  - by afree100

  Edit: I am not asking how to program embedded systems. I am asking how it is done in a practical business setting. I have searched for hours for information on what software developers actually do. More specifically, what coding challenges would one experience daily (e.g. code examples (although obviously not too large), specifics)? I am interested in Linux based embedded systems mainly, but any software development would be helpful (in the C/C++/Assembly areas). Also, regarding this, a distinction between junior, intermediate and senior developers would be helpful. Also, what is the best place to prepare for such things before getting a job for the first time?

• Why is it good not to rely on changing state?

  - by Slomojo

  This question arises out of the question Is Haskell worth learning? Generally a few often repeated statements are made, about how Haskell improves your coding skills in other languages, and furthermore, this is because Haskell is stateless, and that's a good thing. Why? I've seen someone compare this to only typing with the left hand, or perhaps closing your eyes for a day and just relying on touch. Surely there is more to it than that? Does it relate to hardware memory access, or something else which is a big performance gain?

• When to Use workflow engines?

  - by A01_

  I'm totally new to this concept from design perspective. I've worked in past on some of the workflow engines as programmer but never had a clarity on why we chose the work-flow engines in first place. And as programmer I know that there are at least 100 ways to do anything when you are writing code but only few of the ways are the best! I still don't understand which use cases are best solved by workflow engines (or rather their concept) than designing a good DI enabled application. I'm looking for any general characteristics of domain-neutral use cases, where work-flow engines are one of the the best options. So my question is: What are general characteristics of a requirement which can be taken as a signal for opting for a good workflow engine and coding around it? Cheers!

• Android Java: Way to effectively pause system time while debugging?

  - by TheMaster42

  In my project, I call nanoTime and use that to get a deltaTime which I pass to my entities and animations. However, while debugging (for example, stepping through my code), the system time on my phone is happily chugging along, so it's impossible to look at, say, two sequential frames of data in the debugger (since by the time I'm done looking at the first frame, the system time has continued to move ahead by seconds or even minutes). Is there a programming practice or method to pause the system clock (or a way for my code to intercept and fake my deltaTime) whenever I pause execution from the debugger? Additional Information: I'm using Eclipse Classic with the ADT plugin and a Samsung SII, coding in Java. My code invoking nanoTime: http://pastebin.com/0ZciyBtN I do all display via a Canvas object (2D sprites and animations).

• How to properly code in Unity? [on hold]

  - by Vincent B.

  I'm fairly new to Unity (yet I touched it and made a few proto with it) and I'd like to know how I'm supposed to work with it. I'm student in programming so I'm used to C/C++ with SDL/SFML, writing code and only using Input/Graphics/Network libs. I followed a few Unity guides and it was way more around drag & drop on scenes and a bit of scripting to activate it all, which disturbed me. So I fond a way to only use one GameObject and use a Singleton to launch code and display stuff (for 2d games at least). At the end of the day I make games not using "Instantiate" or such at all. Is it the right way ? Am I supposed to do this ? How much are your scenes populated (in a professional environment) ? When should I stop coding and start using the editor ?

• using static methods and classes

  - by vedant1811

  I know that static methods/variables are associated with the class and not the objects of the class and are useful in situations when we need to keep count of, say the number of objects of the class that were created. Non-static members on the other hand may need to work on the specific object (i.e. to use the variables initialized by the constructor) My question what should we do when we need neither of the functionalities? Say I just need a utility function that accepts value(s) and returns a value besed solely on the values passed. I want to know whether such methods should be static or not. How is programming efficiency affected and which is a better coding practice/convention and why. PS: I don't want to spark off a debate, I just want a subjective answer and/or references.

• Can't open Windows 8 after installing ubuntu 12.04

  - by Pyttar

  Yesterday, I tried ubuntu 12.04 LTS and I liked it, so I installed it in my computer with Windows 8. I managed to create a disk partition in Windows and I named it U:\UBUNTU. Then I installed Ubuntu inside this partition, but now, when I try to enter in my Windows 8, it gives me an error message: error: Secure Boot forbids loading module from (hd0,gpt5)/boot/grub/ntfs.mod. error: no such device: 2402319002316706 error: unknow command 'drivemap'. error: invalid EFI file path. Press any key to continue... What can I do? Please I need urgent help, I need to access to Windows 8 and I don't want to lose any data... I checked for the Windows disk and I can se there's all my information there, so, I didn't lose anything. Thanks.

• How to properly shield a Product Owner from outside?

  - by xsAce

  Update: We are a very small team (3 people) and thus I (Scrum Master) and the Product Owner are also developers doing some coding. We are aware of this situation and we are actively trying to recruit some new talents. But it's hard! Meanwhile... we need to adapt... so my question: The Product Owner complains about having too much outside noise (mainly stakeholders feature requests), and he can't focus on the sprint realisation. We agree that we should try to educate people on our process implications (sprint durations and product backlog), to reduce the noise. But as a Scrum Master, how am I supposed to shield a PO from outside? Isn't he supposed to be in contact with the management and business? Also, if people outside don't want to waste too much time learning agile, what is the best way to educate them?

• Is there a way to develop desktop software using PHP?

  - by user1492018

  I have to develop a real estate marketing CRM software for my client - where the application is installed on desktop but can also be accessed from web. 2 reasons why they want the application to run from desktop : So that it can work with/without internet connection They don't want their complete data to be online They want to access few of the data like property listing & inquiries (managed from desktop application) from their website through secure login & password. The data that is entered in desktop application should be automatically synchronized with the website application. I was wondering if there is a way to develop this kind of software using PHP & MySQL. If yes, it will be great if anyone can provide me the referral link.Else please suggest, which language should I use.

• Which is better? Native App or hybrid App?

  - by Prabakaran

  I want to develop a simple App for iOS, Android and windows phone. I just wondered that a simple HTML5, JS and CSS combination can work in all of these platforms. I want to know which one will be efficient? No problem with time and coding. But if i can achieve everything with HTML5-JS itself, i will chose Hybrid development. I want to know the major difference between the Native and Hybrid Development with example(I know that the main difference is HTML5-JS supports cross platform). Note : I am not making a game app.

• Is it possible to boot Ubuntu using the Windows bootloader?

  - by badp

  As noted by many people, Windows 8's UEFI requirements might will won't get in the way of installing Linux (or whatever), as the replacement bootloader will also need to be signed somehow. Some systems All systems will let you disable the signature requirement, but the feature might be hidden to disable or you might not be willing to give up on the benefits of a secure bootloader. Is it necessary to replace the bootloader in the first place? To keep ourselves to software that's gone golden, how can I install Ubuntu 11.04 using Windows 7's own bootloader?

• Where is the best place to start projects and attract developers?

  - by user49557

  I want to develop software for Linux or cross-platform. I want to work with other open-source and non-profit developers. I want a place where Ubuntu or other developers come to start open-source or commercial projects, and we can join the projects or start our own projects. I know there are social coding sites, but where can I start the project, and invite people or let people join? Then we can submit software to sourceforge.net. I know we can start projects at sourceforge.net, but is there anything more dedicated for Ubuntu developers, especially for Ubuntu and for the Ubuntu Software Center? Would you recommend Launchpad, sourceforge.net, github, gitorous or others?

• As a minor, how can I make programming profitable? [closed]

  - by lesderid

  Possible Duplicate: Can I be “too young” to get a programming job? I’m 15 and I want to Freelance I've always loved programming. I started when I was about 8 with making some silly WinForms applications in VB.Net that basically did nothing. Now, I'm 15 and I would say I'm quite good C# and I'm reading through Jon Skeet's C# In Depth. I also have some experience with VB, C++ and Assembler (mostly reverse engineering). I really love coding, which got me wondering about college, what I can study to get into the software business. However, I would like to earn some money now, so I can spend it on better hardware, on development tools or on other hobbies. This is hard because I don't have any work experience nor have I done any programming-related studies. It's also not legal for me to do any freelancing jobs as I'm under the age of 18. How can I use my current experience at my age to earn some money?

• Ubuntu 13.04 not detecting operating system Windows 8

  - by hualur

  I have a Samsung NP740U3E with pre-installed Windows 8 (boots with UEFI). I installed Ubuntu 13.04 without problems. Later, Windows 8 did a BIOS update which messed up everything, nothing would boot. I recovered everything and went back to fabric settings. Now Windows 8 works fine, but when I try to install Ubuntu it does not detect any operating system, so I can`t install Ubuntu alongside Windows. I`ve googled as much as I can, ran a boot-repair, disabled fast- and secure-boot. I have a GPT disc, been looking into gdisk without luck. Here`s my boot-repair summary http://paste.ubuntu.com/5835719/ Is it necessary to convert the GPT disc to MBR? Is it possible to hard-reset the disc "even more" than fabric settings? Thanks in advance.

• How well does Ubuntu run on the ASUS Eee tablet?

  - by Const

  I'm considering buying an ASUS Eee Transformer Prime. I mainly want it so I can do some light web coding on the go. I commute a lot and most of my time is spent on the trains unfortunately. I know that it is possible to install Ubuntu on the transformer prime. I'm also aware that it is not stable since its something new. I'm wondering if anyone has tried it, how responsive/ fast is it? Does the batter die quickly?

• where do you track team Decisions

  - by rerun

  I have been on many development teams and as the team matures decisions about direction are made. These decisions often come back up over and over. Like why don't we fill in this field why didn't we use memcache over a custom solutions. These decisions add up over time and become a significant part of style guides coding standards and unit tests. My question is I have never run into a good way of tracking these decisions or the discovery that went into making them. Does anyone have a best practice.

  I am new to developing computer graphic applications in c++ using OpenGl. I want to develop games but I really am facing problems when it comes to understanding concepts like trajectory, collisions, gravity and also the use of various physics engines that are available. when i search the internet I kind of get lost because they aren't for beginners like me. There is some hardcore mathematics, physics and coding involved. I need to pick the concepts that are mostly needed in game dev like trajectory, collision etc. Any good tutorials that can help me out in picking these concepts from the start.

• Want to learn a new language. Not sure which to pick.

  - by Regravity

  I've been coding in Batch, VBS and AutoIt for AGES, and while its been great and I've made some pretty complex desktop applications in AutoIt, I'd like to advance to something that is more flexible / powerful. I've found that I really love programming desktop applications to solve a wide variety of problems which is what I've been doing with AutoIt. I've done a lot of research on different languages, but I'm torn between a few, namely C++, C# and Python. Can anyone suggest which language I should tackle next? And reasons why I should?

• How to make Classic ASP interesting if you are stuck with it?

  - by reno812

  I used to work on a really small outsourcing company (4 programmers and the boss), then when the stress and the frequent long shifts made the situation unbearable I made the switch to a better paid job with a more relaxed schedule that allows me some more free time. The problem, however, is that for the most part, everything is coded in Classic ASP that interfaces with a custom made C++ queueing system that stores everything in AS400 systems. My boss used to be one of the developers that made the initial efforts towards this, and naturally won't ever approve a switch to another languages / technologies despite the increasing difficulty that represents developing today business needs with yesterday tools. I'm pretty much stuck coding with Classic ASP in the foreseeable future, and I'm struggling to find ways to make it at least interesting, as I used to work with .NET and Java previously, and I feel like I'm going backwards... Any advice?
