  • No startup sound

    - by Laci Bacsi
    Despite numerous attempt, and advise, this is what I applied. sudo cp /usr/share/sounds/ubuntu/stereo/* /usr/share/sounds/ Type this: cd /dev ls -l |less find 14, [0-...] This file for audio you can type cat /etc/passwc >/dev/dsp dsp if speaker device This is not a big deal but I'm an OCD person, so I would like that it works. An other issue is the screensaver, I can not watch movies. I understand that Ubuntu default settings are "Turned off start up sound, and 10 min screensaver auto" If I would be allowed to a suggestions, it is the followings: Is that so problematic to create a check box to check or un check this futures, just to be able to enjoy your product fully? Furthermore I'm reading a lot of similar issues on blogs... Annoying

  • State of the (Commerce) Union: What the healthcare.gov hiccups teach us about the commerce customer experience

    - by Katrina Gosek
    Guest Post by Brenna Johnson, Oracle Commerce Product A lot has been said about the healthcare.gov debacle in the last week. Regardless of your feelings about the Affordable Care Act, there’s a hidden issue in this story that most of the American people don’t understand: delivering a great commerce customer experience (CX) is hard. It shouldn’t be, but it is. The reality of the government’s issues getting the healthcare site up and running smooth is something we in the online commerce community know too well.  If there’s one thing the botched launch of the site has taught us, it’s that regardless of the size of your budget or the power of an executive with a high-profile project, some of the biggest initiatives with the most attention (and the most at stake) don’t go as planned. It may even give you a moment of solace – we have the same issues! But why?  Organizations engage too many separate vendors with different technologies, running sections or pieces of a site to get live. When things go wrong, it takes time to identify the problem – and who or what is at the center of it. Unfortunately, this is a brittle way of setting up a site, making it susceptible to breaks, bugs, and scaling issues. But, it’s the reality of running a site with legacy technology constraints in today’s demanding, customer-centric market. This approach also means there’s also a lot of cooks in lots of different kitchens. You’ve got development and IT, the business and the marketing team, an external Systems Integrator to bring it all together, a digital agency or consultant, QA, product experts, 3rd party suppliers, and the list goes on. To complicate things, different business units are held responsible for different pieces of the site and managing different technologies. And again – due to legacy organizational structure and processes, this is all accepted as the normal State of the Union. Digital commerce has been commonplace for 15 years. Yet, getting a site live, maintained and performing requires orchestrating a cast of thousands (or at least, dozens), big dollars, and some finger-crossing. But it shouldn’t. The great thing about the advent of mobile commerce and the continued maturity of online commerce is that it’s forced organizations to think from the outside, in. Consumers – whether they’re shopping for shoes or a new healthcare plan – don’t care about what technology issues or processes you have behind the scenes. They just want it to work.  They want their experience to be easy, fast, and tailored to them and their needs – whatever they are. This doesn’t sound like a tall order to the American consumer – especially since they interact with sites that do work smoothly.  But the reality is that it takes scores of people, teams, check-ins, late nights, testing, and some good luck to get sites to run, and even more so at Black Friday (or October 1st) traffic levels.  The last thing on a customer’s mind is making excuses for why they can’t buy a product – just get it to work. So what is the government doing? My guess is working day and night to get the site performing  - and having to throw big money at the problem. In the meantime they’re sending frustrated online users to the call center, or even a location where a trained “navigator” can help them in-person to complete their selection. Sounds a lot like multichannel commerce (where broken communication between siloed touchpoints will only frustrate the consumer more). One thing we’ve learned is that consumers spend their time and money with brands they know and trust. When sites are easy to use and adapt to their needs, they tend to spend more, come back, and even become long-time loyalists. Achieving this may require moving internal mountains, but there’s too much at stake to ignore the sea change in how organizations are thinking about their customer. If the thought of re-thinking your internal teams, technologies, and processes sounds like a headache, think about the pain associated with losing valuable customers – and dollars. Regardless if you’re in B2B or B2C, it’s guaranteed that your competitors are making CX a priority. Those early to the game who have made CX a priority have already begun to outpace their competition. So as you’re planning for 2014, look to the news this week. Make sure the customer experience is a focus at your organization. Expectations are at record highs. Map your customer’s journey, and think from the outside, in. How easy is it for your customers to do business with you? If they interact with many touchpoints across your organization, are the call center, website, mobile environment, or brick and mortar location in sync? Do you have the technology in place to achieve this? It’s time to give the people what they want!

  • Security for LDAP authentication for Collabnet

    - by Robert May
    In a previous post, I wrote about how to get LDAP authentication working in Collabnet. By default, all LDAP users are put into the Users role on the server.  For most purposes, this is just fine, and I don’t have a way to change this.  The documentation gives hints that you can add them to other roles, but for now, I don’t have the need. However, adding permissions to different repositories is a different question. To add them, go to the repositories list, select Access Rules and then you can enter in their username, as it sits in Active Directory to the lists for the repositories or for the predefined groups that you have created.  To my knowledge, you cannot use the Active Directory groups in collabnet, which is a big problem.  Needing to micromanage users really limits the usefulness of the LDAP integration.

  • Why does 'quickly package' fail with "An error has occurred when creating debian packaging"?

  • How can i get ubuntu to run smoother?

    - by Knuckles
    I am relatively new to ubuntu [I've used it before and loved it but one day i just randomly couldn't connect to the internet anymore so i switched back to windows... also netflix doesn't work in ubuntu...] and I've noticed that when i used it before everything ran very smoothly and the window animations and stuff like that were just beautiful. now though, everything is choppy and just ugly really. I wanna say its because i was using an older kernel but i really don't know. Anyway, i guess my point is, How can i get it to look pretty again? i really do wish i could be more descriptive but... yeah... I'm on Maverick btw. if anymore information is required i will happily oblige, just let me know.

  • Should I be using a game engine?

    - by Kyle
    I'm an experienced programmer, but I'm completely new to making games. I'm thinking of making an iPhone game that is similar to a 2d tower defense type game. In the web programming world, it would be a big waste of time to make a website without using some sort of web framework (eg ruby on rails). Is that the same for making games? Do people mostly use some sort of framework/game engine for making a game? If so, what are the popular ones for iOS?

  • Photos - do I really need to look for the author and ask his permission when posting them on my site?

    - by user6456
    When I find a photo somewhere on the internet, without any explicit information of whether I can re-publish it on my own website, without any hint of who is the owner/author of that photo, can I still do it? I'm puzzled here cause I've seen like millions of websites, often very big, that repost photos, most probably found via google and it's VERY unlikely they bothered to look for and contact the author of that photos. Is every one of that sites likely to be sued at any moment? What about the case of forums and content provided by users - there is virtually no way of prevention here.

  • Whats New in RadMap for Silverlight / WPF in Q1 2010

    Now that the Q1 2010 release has passed I would like to bring to your attention the official release of one of our newest controls - RadMap for Silverlight [and WPF]. Most of you who are actively involved into the business of data visualization solutions probably are aware that with the Q3 2009 release last year we released a public beta (CTP) version of our map control and it naturally evolved into a fully-fledged control for our current official release. First of all – a BIG thanks to all of you early adopters, who gave the control a try and shared constructive feedback (and also lots of kind words ;)) with us and helped this to happen. So in the good tradition of my original overview of the CTP version of RadMap, I would like to highlight some of the most exciting new features that you might have missed in ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Anyone know about AppDynamics? Does Microsoft already have something similiar? Event viewer? Im confused

    - by punkouter
    We have a big collection of java (80%) and .Net (20%) apps.. And the people in charge want a way to monitor the applications somehow. So they told me they are interested in AppDynamics? I have spent a bit looking into it but I still don't get it. Can someone tell me what its about ? From my understanding it seems like you would someone inject the AppDynamics API in your code to tell about differnt events that occur? So sounds like Event Viewer ? I am on the .NET side of this and seems to me we can just write data to a log and report off of that data.. I don't get what the additional complexity of using'AppDynamics' does. Maybe it is overkill ??

  • Network Computers Not Showing up

    - by Muhnamana
    Alright, 3 machines running, two using Ubuntu 11.10 and one on Mac OS X. On the two Ubuntu machines, both have samba installed and configured on the same workgroup, "HOME". On machine 1, I can see all networked machines. On machine 2, I can only see the Mac OS X machine. It doesn't show the other Ubuntu machine. What am I missing on machine 2 to see all networked computers? Any suggestions are welcome. I'm pretty much stumped.

  • What made you contribute to that open source project? [closed]

    - by Ermin
    I'm interested in real experience and personal answers not just those standard worn out "benefits of contributing to open source" that we all memorized by heart by now. I've met many people who contribute to open source project and almost never did this topic come up: why did they contribute to this open source project. So, if you've contributed to an open source project before in any way, can you please pause for a second and try to remember what really made you decide to contribute to that particular project. Was it a random decision, was it because you were bored, was it because the company you worked for was already using it and you contributed as part of your job, was it because the project was too big you wanted to get contracts, or the project was too small you wanted to build it, or because your prof or co-worker asked you to help with his open source project, or..... To substantiate your reasons, please mention the project name and rate your involvement (heavy, occasional, light, once).

  • Is there a 'design pattern' type listing of common algorithms?

    - by KevinM1
    Is there a 'design pattern' styled listing of common/popular algorithms anywhere? Specifically, something that has a similar format along the lines of: Algorithm Name: e.g., Quick Sort, Bubble Sort, etc. Problem: A description of the stereotypical problem the algorithm is supposed to address Description: Description of the solution Implementation: Code examples of the solution Big O Rating: Self-explanatory Similar Algorithms: Algorithms that address the same problem in different ways, or similar problems I really like the GoF design pattern listing style, and I think it would help me learn various algorithms better/easier if I could find a resource that was similar in terms of organization.

  • Encrypt images before uploading to Dropbox [migrated]

    - by Cherry
    I want to encrypt a file first before the file will be uploaded to the dropbox. So i have implement the encryption inside the uploading of the codes. However, there is an error after i integrate the codes together. Where did my mistake go wrong? Error at putFileOverwriteRequest and it says The method putFileOverwriteRequest(String, InputStream, long, ProgressListener) in the type DropboxAPI is not applicable for the arguments (String, FileOutputStream, long, new ProgressListener(){}) Another problem is that this FileOutputStream fis = new FileOutputStream(new File("dont know what to put in this field")); i do not know where to put the file so that after i read the file, it will call the path and then upload to the Dropbox. Anyone is kind to help me in this? As time is running out for me and i still cant solve the problem. Thank you in advance.

  • Best strategy for supporting multiple server communication from iPhone/android app?

    - by tipycalFlow
    I'm making an app that will be used in multiple hospitals in the US. As per HIPAA compliance requirement, every hospital will have its own server that complies with these requirements of ensuring patient data security, etc. Now the task is that the app should communicate with a particular server based on the login info. An additional requirement is that new hospitals(servers) are likely to be added along the way, even after the app is available on the market. So basically, according to some login credentials, the app should communicate with the server of the hospital assigned to that person. One pretty crude way is to set up our own server which links the hospitals with the login info and accordingly, provides a base-url for data exchange. Is there a more efficient way to handle this?

  • 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?

  • Ugly LibreOffice font

    - by tuhyk
    I have been experiencing this super annoying bug with fonts in LibreOffice. Please see below screenshot. The spaces between letters are just messed, no matter what font or level of zoom I choose. When I change the zoom level, the spacing is actually changing but still looks very ugly. I have a pretty much default instalation of Ubuntu. I installed a couple of fonts (droid, mscorefonts). I did not change any font settings. Fonts in other applications looks great. When I open the very same text in Google Docs or MS Web Word, it looks perfect. I would appreciate any help concerning this issue. Thanks!

  • Why is Prolog associated with Natural Language Processing?

    - by kyphos
    I have recently started learning about NLP with python, and NLP seems to be based mostly on statistics/machine-learning. What does a logic programming language bring to the table with respect to NLP? Is the declarative nature of prolog used to define grammars? Is it used to define associations between words? That is, somehow mine logical relationships between words (this I imagine would be pretty hard to do)? Any examples of what prolog uniquely brings to NLP would be highly appreciated.

  • Where can I learn to write my own database?

    - by Buttons840
    I'm interested in writing my own database - a triple-store. Are there any good resources to help with the challenges of such a project? Or more generally: How can I learn to write my own database? Some specific issues I'm unsure of: How is the data actually stored on the file-system? A flat-file seems easy enough, but a database is a lot more then a flat-file. What kinds of things are typically stored (or cached) in memory? How are indexes created and stored? How is ACID compliance achieved? Etc. This is a big topic, but knowing how to store large amounts of data in a reliable way is good to know. (My investigation into existing triple-stores was summarized back in 2008; not much has changed in 4 years it seems. This is why I want write my own.)

  • What are good/fast methods to pull data from a database using JavaScript?

    - by Yatrix
    I'm pretty new to web technologies and I am creating a filter control that will have cascading controls. We are doing a lot of this through JavaScript and are debating the best route to take to the database. HTTPHandlers, WebServices and Ajax are all being considered (or a combination of them). We want to be able to handle a million rows in theory, so it has to be scalable to at that. We are going through JavaScript as our page must not do post-backs, if your'e wondering. I'm asking from an architectural standpoint, but will take any useful information. Links, control suggestions - anything you have, I'll happily listen to.

  • migrating sharepoint databases

    - by Alex Bransky
    If you're wondering how to migrate your SharePoint databases to a new server, this Microsoft article is actually pretty useful, though still overly complex like most of their other articles. http://technet.microsoft.com/en-us/library/cc512725.aspx The one thing I would change is that they seem to recommend installing SQL Server Configuration Manager on web servers, when all that was needed in my case was to add an entry to the hosts file on the SharePoint web server that used the IP address of the new SQL Server with the name of the old SQL Server.  This might not be appropriate in cases where the old server is not being decommissioned.

  • Any Other Distros with Gnome 2.32?

    - by Gowtham
    I've used Ubuntu for almost a year and I pretty much don't like the Unity environment and I installed BackTrack R3 in my laptop which uses GNOME 2.32 and I'm much impressed with that and made a decision to move to GNOME but, it is currently in version 3.x and it has been said that there is no GNOME 2.x versions are supported. I don't like the new GNOME and surfed the internet for finding a distro with that version and support. But, I can't find one. Can you specify a good distro with GNOME 2.x and Debian package installers?

  • Maya and Game Engines (i.e. Environment Testing)

    - by DiscreteGenius
    What does it mean if I'm designing an environment and I want to test it in the game engine, to see what its like to "run" [or fly] around my environment? I heard an instructor say that exact thing in a Maya training video and I'd like to know more about "How Game Engines and Maya are related to each other." He stated this would be done to see how things look in "size" (e.g. I assume he meant: 'How big is the cathedral, bridge, wall, building, etc.'). I've tried to research such information but it's too complicated, and detailed. I just want a simplistic response to my query. Thanks to everyone willing to help and not criticize my question.

  • Is Java a good choice for cross-platform games?

    - by CommunistPancake
    I'm looking to create a game in Java and would like it to work on Windows, Linux, and Mac. I'm pretty sure C# is a bad choice for this, and I don't have enough experience in C or C++. I want to stay away from Flash. Therefore, Is Java a good choice for me? Mostly, I use C#, and think that Java is similar, so I assume it won't be that hard to learn. But is it fast enough? Is there a language more suited for my needs than Java?
