• My Rhythmbox plugin can't meet the Ubuntu Software Center "my-app" requirements

  - by allquixotic

  At http://developer.ubuntu.com/publish/my-apps-packages/ the following technical requirements are cited: Technical requirements In order for your application to be distributed in the Software Centre it must: Be in one, self-contained directory when installed Be able to be installed into the /opt/ directory (*) Be executable by all users from the /opt/ directory (**) Write all configuration settings to ~/.config/ (This can be one file or a directory containing multiple configuration files) A Rhythmbox plugin cannot satisfy any of these requirements. Rhythmbox has compiled-in locations where it looks for installed plugins. So, is there no way for me to publish my app in Ubuntu Software Center? Would it have to go into Universe repository (which would require tremendously more work and political maneuvering to get it accepted)? I already have all the Debian package infrastructure built for it, so I have made a PPA for it.

• No sound after installing a new Graphics Card

  - by Dan

  I've just upgraded my graphics card to an Asus Geforce 210 and now my system has no sound. I've ran Update Manager and the Additional Drivers utility which installed the latest Nvida driver. The graphics card is connected to my TV via a DVI-to-HDMI (DVI at the PC end) cable for the visual connection, and an audio jack from my onboard soundcard for my audio connection. Any ideas on how to resolve this? I ran this command ubuntu-bug audio And it outputted this: You seem to have configured PulseAudio to use the "pci-0000_05_00.1" card, while you want output from "NFORCE - NVidia CK804". I've tired a bit of messing about with the audio settings but can't get anything to work.

• Do you think code is self documenting?

  - by Desolate Planet

  This is a question that was put to me many years ago as a gradute in a job interview and it's kind of picked at my brain now and again and I've never really found a good answer that satisfies me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

• Advice needed: Software Development [closed]

  - by Hunter McMillen

  I recently graduated from college with a B.S. in Computer Science, and am now currently attending the same college to get an M.S. in Computer Science. I know lots of things about Computer Science and programming but throughout all of my coursework I have never had to develop a single complete application, the projects were always relatively small (~300-500 lines of code). Basically, my overall I am about to have these two degrees and I feel like I don't know anything about software development or design; which doesn't make a whole lot of sense. I am looking for ways to fill in the gaps in my knowledge, I would love people's advice on these questions: 1) How do you design good software? Where do you start? 2) What makes a good software developer? Sorry for the convoluted question, but in my mind it is a convoluted situation. Thanks Edit Thanks everyone for your advice.

• Top reasons why programmers are fired. [closed]

  - by Blankman

  Have you ever been fired before, or one of your colleagues? What were the main reasons for him being fired? The objective of this question is to get a list/description of other peoples experiences too see if we can come up with a theme of why people are let go. For those that work for consulting companies, I would guess one of the main reasons would be a developer is just too slow pumping out code. So my guesses would be: 1) attitude 2) too slow Please specify if you are saying something from experience or just guessing.

• rt73.bin for Ubuntu 12.04 LTS?

  - by fNek

  I have a D-Link USB WLAN stick and want to install Ubuntu 12.04 alternate. The installer asks me to insert an exchangable drive containing 'rt73.bin', the driver. I cannot find any binary downloads, but cannot build the package, because I have no other linux PC. What can I do? //EDIT: The reason why I want to do this during setup is that I want to setup an LTSP server. I only found guides that assume one has Internet connection - but I have not. What can I do?

• Develop secureness first or as a later step?

  - by MattyD

  The question Do you actively think about security when coding? asks about security mindset while programming. Obviously, a developer does need to think about security while coding — SQL injection, password security, etc. However, as far as the real, fully-formed security, especially the tricky problems that may not be immediately obvious, should I be concerned with tackling these throughout the development process, or should it be a step of its own in later development? I was listening to a podcast on Security Now and they mentioned about how a lot of the of the security problems found in Flash were because when Flash was first developed it wasn't built with security in mind (because it didn't need to) — therefore Flash has major security flaws at its core. I know that no one would want to actively disagree with "think security first" as a best practice, but many companies do not follow best practices. So, what is the correct approach to balance between needing to get the product done and developing it securely?

• Free OS with MS Windows Archetecture and capabilities

  - by Nayana Adassuriya

  Currently most of the PC users mostly depend on the windows OS and they would not go away from that beaus of the hand on usage knowledge about and also because of the look and feel habituation. But there are plenty of Linux base Desktop operation systems there such as UBUNTU, FEDORA. Users do not tend to go for those OSs (specially office environments) because most of the 3rd party software and tools (such as Photoshop, flash, Visual Studio) mostly can install only in windows operating system. So I'm thinking why we cant create a free OS same as Windows. That is capable to install software that created for windows. that can communicate with windows servers and exchange etc.. . Simply it should be a free OS with all the capabilities of Windows OS. How about your idea?

• Browser-based MMOs (WebGL, WebSocket)

  - by Alon

  Do you think it is techniclly possible to write a fully-fledged 3D MMO client with Browser JavaScript - WebGL for graphics, and WebSocket for Networking? Do you think future MMOs (and games generally) will wrriten with WebGL? Does today's JavaScript performance allow this? Let's say your development team was you as a developer, and another model creator (artist). Would you use a library like SceneJS for the game, or write straight WebGL? If you would use a library, but not SceneJS, please specify which. Thanks!

• Windows 8 ne serait pas encore finalisé pour le patron d'Intel, qui estime que des améliorations sont encore nécessaires

  Windows 8 ne serait pas encore finalisé pour le patron d'Intel qui estime que des améliorations sont encore nécessaires Microsoft va officiellement lancer Windows 8 le 26 octobre avec une nouvelle génération de tablettes et PC fonctionnant sous le système d'exploitation.

• Phones, Nokia, Microsoft and More

  - by Bill Evjen

  The phone revolution that is under way at the moment is insanely interesting and continuously full of buzz about directions, failures, and promises. The movement started with Apple completely reinventing what a smart phone was all about and now we have the followers. Though – don’t dismiss the followers, they are usually the ones that come out with the leap frog products when most of the world is thinking about jumping on. Remember the often used analogy – the USA invented the TV – but it was Japan that took it to the next level and now all TVs are from somewhere else other than the USA. Really there are two camps for the phones – the Cool Kids and other kids that no one wants to hang out with anymore. When it comes to cool – for some reason, the phone is an important part of that factor. Everyone wants to show their phone and its configuration (apps installed, etc) to their friends as a sign of (1) “I have money” and (2) I have smarts/tastes/style/etc when it comes to my applications that are on my phone. For those that don’t know – the Cool Kids include: Apple – this is quite obvious as everything Apple produces is in the cool camp. Just having an Apple product on your person means you can dance. Google – this is one of the more interesting releases as they have created something called Android (which in it’s own right is a major brand in itself). Microsoft – you might be saying “Really, Microsoft is cool?”. I would argue that they are indeed cool as it is now associated with XBOX 360, Kinect, and Windows 7. Gone are the days of Bob and that silly paperclip. Well – that’s it. There is nobody else I would stick in that camp. The other kids that weren’t picked for that dodgeball team include: Nokia Motorola Palm Blackberry and many many more The sad part of all this is that no matter what this second camp does now, it won’t be able to get out of this bucket easily. They will always be associated as yesterday’s technology and that association will drive the sales of the phone purchasers of the world. For those in that group, the only possible way out is to get invited to the cool club by one of the cool club members in the hope that their coolness somehow rubs off. To me, this is the move that Nokia is making. They are at this point where they have realized that they don’t have the full scope of the required end to end solution to make this all work. They have the plants to build the phones and the reach of the retailers that sell what they have. What they are missing is the proper operating system for the new world of multi-touch form factor phones. Even the companies that come up with some sort of new operating system for this type of new device, they are still associated with the yesterday and lack the developer community behind them to be the real wave of adoption that this market needs. Think about that – this is a major different between Nokia/Blackberry when you compare it to the likes of Apple, Google, and Microsoft. These three powerhouses having a very large and strong development community that will eagerly take on new initiatives using the skillsets that they have already cultivated over the years of already working with the company. This then results in a plethora of applications that are then placed on an app store of some kind. The developer gets a cut and then Apple/Google/Microsoft then get their cut. It is definitely a win-win. None of the other phone companies and wannabies can provide the same results. What Microsoft was missing was the major phone manufactures coming on board to create and push forward with the phones that are required to start the wave. This is where Nokia can come in and help Microsoft. They have the ability to promote the Windows Phone operating system on a new wave of phones. This does mean that Nokia will sell phones, but they lose out on the application store that they might have been thinking about making some money on as well as controlling the end to end solution. What is interesting is in questioning to oneself if Microsoft will purchase Nokia. It really depends upon how they want to compete and with whom Microsoft views as the major competitor. For instance, they can purchase Nokia and have their own hardware company and distribution network for phones – thereby taking on a model that is quite similar to Apple. On the other hand, they could just leave it up to the phone hardware companies such as Nokia and others to build and promote phones in a model that is similar to Google. Both ways have pluses and minuses. If they own the phone manufacturer, they really can put some thought into the design and technical specifications of the phone that is really designed to exactly how they want it. Microsoft has shown that they have this ability – especially with the XBOX initiative they have done over the years. Think about how good and powerful they have moved forward with XBOX – and I am not talking about just copying what others are doing, but coming up with leapfrog products that are steps ahead of everyone else. Though, if they didn’t do it themselves, they could then leave it up to the phone manufacturers to drive each other to build better and better phones that run the Microsoft OS – competition drives better products. We have seen this with the Android line of phones that are out there on the market. I have read a lot about Nokia investors really upset about the new Microsoft relationship – but really, this is a great thing. I for one am a fan of this relationship (I am also a Nokia stock holder btw). This will mean better days for Nokia.

• Cutting desktop power usage

  - by steevc

  I'm on a general energy saving mission. I've finally swapped my old CRT monitor for a LCD, so the next step it to optimise the PC power usage. It's using an AMD 64 X2 4600+ CPU which I know can trottle down, but seems to be running at a constant 2.4GHz. A while back I heard about Granola. I've installed it, but when I try to run it I get granola[10568]: Error opening scaling governor file '/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' in read mode granola[10568]: Is cpufreq enabled in this kernel and do you have a CPU which supports DVFS? granola[10568]: Can't manage DVFS for any CPUs I'm happy to use other applications if Granola is not optimal or viable.

• How to handle compensation issue

  - by Ali

  I consider myself an expert Software Developer. Recently, I noticed my current company posted a new job through a recruting firm requiring half experience than I have and even lesser set of skills. However, they are offering the same salary as my current salary. When I joined my current company a year ago, they declined to pay my asking salary. My evaluations are good and there are critical projects in the pipeline where my involvement is crucial for their success. I'm little confused on how to handle this situation. I don't want to come across threatning or any thing like that.

• Links to facebook.com/company-page redirect to facebook.com

  - by Teo

  For the last 2 days I've been trying to find the reason why the link to my website's Facebook page doesn't work anymore. The link went to facebook.com/company-page, but now redirects to facebook.com. I assume that I mistakenly changed something in the Facebook developer area, but I can't remember what it was. I guess I saw some redirect in the tab, but I'm not sure since it's changing too fast to facebook.com. The original link in the footer is correct: <a href="http://facebook.com/company-page " target="_blank" class="facebook_ico"></a> Any ideas?

• Permanently mounting Windows' NTFS partition, fully enabled

  - by Bart van Heukelom

  I'm transforming a Windows 7 PC into a dual boot system with Ubuntu 10.10. Following other questions on this site, I've mounted my Windows drive by adding this to fstab UUID=blabla /windows ntfs users,defaults,umask=000 0 0 It appears to work well, I can read and write, but it appears to be a bit crippled still. When I tried to update an SVN working copy with RabbitVCS, it complained that it couldn't write to a temporary file inside the working copy, even though the permissions are all on 0777 inside /windows (by default, I haven't done that manually). It even corrupted that working copy :( It works when I use the command line SVN client with sudo, but that's hardly user friendly.

• When should I increment version number?

  - by ahmed

  I didn't learn programming at school and I do not work as a (professional) developer, hence a lot of basics are not quite clear to me. This question tries to clarify one of them. Now let's suppose that I have issues #1, #2 and #3 in my Issues Tracker that are set to be corrected/enhanced for version 1.0.0 and that the last (stable) version is 0.9.0. When should I increment to version 1.0.0 ? When a) just one of the listed above issues is closed or b) when all the issues related to version 1.0 are closed ? Which one is the right way to do it ? And by the right way, I mean what is currently used in the industry. Thanks.
