  • Pulseaudio no sound card detected. Dummy output only

    - by Zach Smith
    I'm using 12.10 Quantal with Openbox and a .xinitrc script at login instead of a display manager. Its a relatively fresh install and I noticed when I opened pavucontrol the only output was a dummy one. I check around and it appears that my soundcard is physically installed but Pulseaudio isn't detecting it. I'm really unsure what I should do but any help getting my audio back would be appreciated. Edit: further info if its at all useful: dante@dante-ubuntu:~$ uname -a && aplay -l && cat /proc/asound/version && head -n 1 /proc/asound/card*/codec#* Linux dante-ubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux aplay: device_list:252: no soundcards found...

  • Database .NET

    - by Guilherme Cardoso
    Database .NET is an awesome tool that allow us manage several database in simultaneous (SQL Server, MySQL, Oracle, etc). What lead me to install this tool was an problem that must be shared by must developers. Tools like SQL Server Management Studio consume to many resources, and if you don't have a decent computer you'll get problems in performance, and that's my case! With Database .NET we can access an SQL Server for example, and make several actions to database (crud operations, manage procedures, etc).Of course that this tool can replace the use of SQL Server Management Studio for example!  But it's really usefull if  you just need to perform small operations because it consumes many fewer resources. This tool don't need to be installed (it can be used as an portable application). One tip: if you are using SQL Server Express for example, don't forget to check the server name in Database .NET connection. In my case i've to change from GUILHERM-196634 to GUILHERM-196634\SQLExpress. Project: http://fishcodelib.com/Database.htm Download: http://fishcodelib.com/files/DatabaseNet3.zip

  • IIS7 Serving .mp4s, not playable on iOS devices.

    - by Danomite
    I've added the proper MIME type to the server, made sure it applies to not only the specific site but even the all of server's sites. The file is accessible and playable in my browser (Chrome) but when trying to pull it up on an iPhone , the debug mode warns me that the "movie could not be played" but on iPad it's "byte_range_error_message" I'm really at a loss here of why iOS devices won't load the video up. I know it's not the video files themselves because I had used the same file on a different server (on a shared hosting package). Any help is appreciated! -Dan

  • Sea Monkey Sales & Marketing, and what does that have to do with ERP?

    - by user709270
    Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.

  • How can videos from Ubuntu drive appear on web page and play in an embedded Flash Player?

    - by nLinked
    I have a shared folder on Ubuntu Server 12.04. Users drop videos in. Ubuntu runs a Cron task to convert them to FLV format and put them into another folder. All I would like is a simple web page that displays all the files in that folder as links, and when you click on the link for the video you want to play, it should play in the same web page inside an embedded Flash/SWF player. Sounds really basic but I'm actually struggling to find a simple solution. Any thoughts appreciated!

  • "My stuff" vs. "Your stuff" in UI texts

    - by JD Isaacks
    When refering to a users stuff should you use My or Your, for example: My Cart | My Account | My Wishlist Or Your Cart | Your Account | Your Wishlist I found this article that argues for the use of your. It says flikr does this. It also says MySpace and MyYahoo are wrong. I also noticed today that Amazon uses the term Your. However, I have heard they are the masters at testing variations and finding the best one, so what you see on their site might be the best variation, or simply something they are currently testing. I personally like the way my looks better, but thats just my opinion. What do you think? What will hever the better impact on customers? Does it really even matter?

  • Audiencing with Forms-Based Authentication (FBA)

    - by PeterBrunone
    This really is no different from when you create an audience with regular old NTLM (Windows Authentication).  The difference is that while the AD provider is set up by default in all environments, the extra membership provider (that you use for Forms Authentication) isn't included anywhere except in the web application where you install it.  To be able to find your FBA users in the audience creation tool, you'll need to add the extra membership provider(s) to the web.config for your SSP site in IIS.  At that point, the People Picker should start recognizing your Forms Auth users, and you can create your audience as needed.

  • Design patterns and multiple programming language

    - by Eduard Florinescu
    I am referring here to the design patterns found in the GOF book. First how I see it, there are a few peculiarities to design pattern and knowing multiple language knowledge, for example in Java you really need a singleton but in Python you can do without it you write a module, I saw somewhere a wiki trying to write all GOF patterns for JavaScript and the entries where empty, I guess because it might be a daunting task. If there is someone who is using design patterns and is programming in multiple programming languages supporting the OOP paradigm and can give me a hint on how should I approach design patterns that might help me in all languages I use(Java, JavaScript, Python, Ruby): Can I write good application without knowing exactly the GOF design patterns or I might need some of them which might be crucial and if yes which one, are they alternatives to GOF for specific languages, and should a programmer or a team make its own design patterns set?

  • Project Management - Asana / activeCollab / basecamp / alternative / none

    - by rickyduck
    I don't know whether this should be on programmers - I've been looking at the above three apps over the past few weeks just for myself and I'm in two minds. All three look good, are easy to use, and I came to this conclusion; Asana is the easiest to use ActiveCollab is the feature rich and easiest flow BaseCamp is the best UX / design But I didn't really find my workflow was any more quicker / efficient, in fact it was a bit slower and organized. Is there a realistic place for them in workflow - should programmers use them for themselves, or only when a project manager can take control of it?

  • How well do laptops with Nvidia Optimus work?

    - by DSJones
    I am considering buying a Dell XPS 15 laptop. The laptop has a nvidia 420m card which should work with linux but I keep reading about the Nvidia optimus technology that isn't supported on Linux. I am not really interested in switching from Nvidia to intel to save power but need to know that the Nvidia card will infact work if i installed Ubuntu. If anyone has experience usung a nvidia card with optimus technology or even better the exact laptop in question (Dell XPS 15 with 1GB NVIDIA® GeForce® GT 420M) it would be great. A major problem holding people back from adopting Linux is this sort of hardware issue. I am a long term Ubuntu user and supporter who can't afford to make a mistake with a purchase like this. I don't want to spend £500+ to find I have no graphics acceleration because Windows7 is not an option.

  • Is donationware a good monetization model for developers?

    - by Nathan Campos
    I've been developing for Android for about 2 years (and ~1 year for iOS), releasing freeware and open source applications (mostly because my AdSense account was disabled in 2010), but recently I had an idea for a great app that I wanted to get some money, since it would take some effort to develop and also I would like to test this "commercial" model to know if this could make me invest more time improving and making my apps better. Since my AdSense account was disabled and then I'll not be about to sell it on the Google Play Store, I thought about making it a donationware so I would distribute it for free (and probably open source too) and users that really liked the app and wanted to give me a thanks and a incentive to continue developing it could donate any amount of money. So, what's your experience with donationware? Is it worth compared to paid apps?

  • Cross-Browser Extension Installation now Possible with Opera and Google Chrome

    - by Akemi Iwaya
    People have been curious if there would be cross-browser compatibility for extensions due to Opera’s recent switch to the browser engine that Google Chrome uses. That question has now been answered. The OMG! Chrome! Blog has put together a nice tutorial on how to get cross-browser extension compatibility set up and working with your browser of choice. Screenshot courtesy of OMG! Chrome! Blog. While it is not surprising that the first steps in cross-browser extension compatibility have been taken, it will be interesting to see how it develops as the process is refined and further development occurs with the ‘new’ Opera. What are your thoughts on this? Is cross-browser extension compatibility really that important? Perhaps you feel that it does not matter? Let us know your thoughts in the comments!

  • Fastest way to document software architecture and design

    - by Karsten
    We are a small team of 5 developers and I'm looking for some great advices about how to document the software architecture and design. I'm going for the sweet spot, where the time invested pays off. I don't want to use more time documenting than necessary. I'll quickly give you my thoughts. What are the diagrams I should made? I'm thinking an overall diagram showing the various applications and services. And then some sequence diagrams showing the most important or complicated processes. About the code it self, I really don't see much value in describing or making diagrams for the code outside the .cs files them self. About text documents, I'm a bit uncertain about when to put down on paper. Most developers don't like to either write or read long documents.

  • 'Other' Features in a programming language

    - by user12960
    Online (i cant remember where) i saw someone mention he wishes programming language has more built in features for tools like documentation and source control. Now i dont understand what needs to be built in for source control since tools like git (sorry but i dont have much experience with others) has everything i need and is very easy to use. Documentation i can understand, perhaps the ability to generate remote procedures calls from source to some kind of IDL would be cool. But really i dont understand what features a programming language can/should have that isnt tied with code generation and syntax (except the two i mention when it comes to libraries). What ideas do you guys have? What is your wishlist?

  • Are nvidia drivers necessary?

    - by Shubham Chaudhary
    The new Ubuntu 14.04 comes with nvidia driver options. My system(Dell XPS) uses nvidia-331. For starters it messed up my text font size. It is so freakishly small with nvidia drivers on. So my question is: Are these drivers really necessary? What performance gain do they provide? Will it help me save some battery life? Basically what are these drivers doing that I was missing before (with nouveau I guess)?

  • How can I become more agile?

    - by dough
    The definition of an agile approach I've adopted is: working to reduce feedback loops, everywhere. I'd describe my Personal Development Process (PDP) as "not very agile" or "not agile enough"! I've adopted TDD, automated building, and time-boxing (using the Pomodoro Technique) as part of my PDP. I find these practices really help me get feedback, review my direction, and catch yak shaving earlier! However, what still escapes me is the ability to reduce feedback time in the ultimate feedback loop; regularly getting working software in front of the end user. Aside from team-oriented practices, what can I do to personally become more agile?

  • Looking Back at PASS Summit 2013 - Location

    - by RickHeiges
    Now that it has been a few weeks since the Summit, I wanted to look back at the location "experiment". Convention Center - It seemed to work well for the conference. There were quite a few areas in the area where you could sit down and get some work down or have a discussion. For the larger welcome reception the first night, I really liked the different areas. If you wanted to enjoy the Quiz Bowl, the ballroom area was set up nicely with big screens so that everyone could see and hear. The area right...(read more)

  • YouTube: Tips by Bitwise Courses on NetBeans

    - by Geertjan
    I really like the potential of YouTube in providing a platform for short info clips that take not much time to produce and about as much time to consume. Huw Collingbourne's Bitwise Courses channel is full of exactly this kind of YouTube clip. Several of his YouTube clips are about or make use of NetBeans. The related Twitter account is @bitwisecourses and the homepage is bitwisecourses.com. Here's a great example, the latest YouTube clip created by Bitwise Courses. Very clear and simple explanation, on a specific and narrow topic, and very short and sweet. And very useful! Didn't know about this feature myself. Direct link to the movie: https://www.youtube.com/watch?v=b0fKT_hFQpU Here's to more of these, they're wonderful. More such YouTube clips are needed, short and precise, on very specific topics. And I'm very happy to promote them, as you can see.

  • Design Code Outside of an IDE (C#)?

    - by ryanzec
    Does anyone design code outside of an IDE? I think that code design is great and all but the only place I find myself actually design code (besides in my head) is in the IDE itself. I generally think about it a little before hand but when I go to type it out, it is always in the IDE; no UML or anything like that. Now I think having UML of your code is really good because you are able to see a lot more of the code on one screen however the issue I have is that once I type it in UML, I then have to type the actual code and that is just a big duplicate for me. For those who work with C# and design code outside of Visual Studio (or at least outside Visual Studio's text editor), what tools do you use? Do those tools allow you to convert your design to actual skeleton code? It is also possible to convert code to the design (when you update the code and need an updated UML diagram or whatnot)?

  • Great Silverlight User Group meeting last night - Thanks Joel!

    - by Dave Campbell
    Last night's Silverlight User Group meeting in Phoenix went really well. We had about 15 in attendance, and everyone seemed engaged with Joel Neubeck's great Windows Phone 7 presentation. When it was over, we gave away a couple copies of Windows 7 Ultimate, one copy of the Expression Suite, an Arc Mouse, a web cam, a bunch of books, other assorted software and some TShirts.  All-in-all I think it was a good time had by all. Thanks to Joel Neubeck for the time and presentation and to Joe's mom for the babysitting! See you all next month.

  • unit testing variable state explicit tests in dynamically typed languages

    - by kris welsh
    I have heard that a desirable quality of unit tests is that they test for each scenario independently. I realised whilst writing tests today that when you compare a variable with another value in a statement like: assertEquals("foo", otherObject.stringFoo); You are really testing three things: The variable you are testing exists and is within scope. The variable you are testing is the expected type. The variable you are testing's value is what you expect it to be. Which to me raises the question of whether you should test for each of these implicitly so that a test fail would occur on the specific line that tests for that problem: assertTrue(stringFoo); assertTrue(stringFoo.typeOf() == "String"); assertEquals("foo", otherObject.stringFoo); For example if the variable was an integer instead of a string the test case failure would be on line 2 which would give you more feedback on what went wrong. Should you test for this kind of thing explicitly or am i overthinking this?

  • Make one monitor act like two, split in half

    - by Nathan J. Brauer
    Context: Ubuntu 11.10, Unity Let's say I have a screen at resolution 1000x500. What I'd like to do is split the screen down the middle so [Unity or X or ?] acts as if there are two displays (each of 500x500). Examples: Unity will display a different toolbar (the top one) on each side of the display. If I maximize a window on the left side of the screen, it will fill the left side only. If I maximize on the right, it will fill the right. If I hit "fullscreen" in youtube (flash) or Chrome or Movie Player, it will only fill the side of the display that it's on. If it's really is impossible to do this with Unity, will it work with Gnome3 and how? A million thanks!

  • High CPU load - Ubuntu 14.04

    - by watt
    I noticed that sometimes when browsing (with other processes in the background), I get very high CPU load for the browser process (over 100%) and the computer becomes really slow. I tried switching from Firefox (with just a few extensions) to Chromium, but same thing happens without me visiting graphics-intense sites, flash sites or anything like that. I also noticed python or node (when running "make") produce the same high CPU load from time to time so this is not necessarily browser-related. When I only have a browser open, it doesn't seem to happen and everything is fine in Windows 7. I switched from unity to gnome3 with no effect. Specs: lenovo w510 (4gb RAM, i7 q820 @ 1.73) + up to date Ubuntu 14.04 64bit. Printscreen: http://imgur.com/8MZJNKC Do you guys have any idea why this might happen? Please let me know if there's other info you need. Thanks!

  • Does TDD lead to the good design?

    - by Eugen Martynov
    I'm in transition from "writing unit tests" state to TDD. I saw as Johannes Brodwall creates quite acceptable design from avoiding any of architecture phase before. I'll ask him soon if it was real improvisation or he had some thoughts upfront. I also clearly understand that everyone has experience that prevents to write explicit design bad patterns. But after participating in code retreat I hardly believe that writing test first could save us from mistakes. But I also believe that tests after code will lead to mistakes much faster. So this night question is asking for people who is using TDD for a long time share their experience about results of design without upfront thinking. If they really practice it and get mostly suitable design. Or it's my small understanding about TDD and probably agile.

  • Book recommend: Start learning web design with css with basic HTML knowledge

    - by Minh Hieu
    I've already known some HTML, tables, link, image,...etc but just at a basic level. Now I want to learn how to build a layout for a website and design also. I want to start building a layout right a way and just learning from it, not really like reading so much theories, explanations. Many books are so verbose, they teach from the beginning of HTML or explain things too much. I don't want to waste my time. So are there any good books for me?
