  • Options for Application Registry

    - by Matt Felzani
    I work for a small software company (about 200 people building 8-10 applications) and I was hoping to get some advice on products that might be out there to manage the information of which clients are using which versions of our products? The most fundamental relationship would be that a "product" has "versions" and a given "version" is used by a "client." Uses would be: Determine which clients use which products Determine which clients are on which versions of a product Determine which clients are exposed to which vulnerabilities because of the version they use Determine which clients cannot move to a new version because of a vulnerability in the new version that they may hit Determine which clients should be approached for an upgrade Any thoughts or product reviews would be greatly appreciated! Thanks in advance.

  • pgadmin III doesn't work due to "The server lacks instrumentation functions."

    - by Chaz SLiger
    When pgAdmin III is used to open a PostgreSQL database the following message appears. There does not seem to be any obvious package listed in the Ubuntu Software Center for this. The server lacks instrumentation functions. pgadmin III uses some support functions that are not available by default in all PostgreSQL versions. These enable some tasks that make life easier when dealing with log files and configuration files. The adminpack is installed and activated by default if you are running the one-click installer of PostgreSQL. On Unix, you may have to install the contrib package, either with your package installer tool or by compilation.

  • DrRacket icon doesnt work?

    - by Laurie
    I installed DrRacket from the Ubuntu Software Center. All went well and an icon appeared however nothing happened when I clicked the icon so I removed it. Then went to the Developer website and downloaded full-5.3.0.21-bin-x86_64-linux-debian-squeeze.sh. I installed this via Terminal with sudo apt-get install racket. The DrRacket icon came back in Dash Home but again clicking it nothing appears to happen. How do I start DrRacket? I am running Ubuntu 12.04 LTS dual boot on a 64 bit Dell

  • The use of LGPL for Commercial use

    - by Smarty Twiti
    I am trying to make my first app for sale, I would like to ask some questions for those who have already sold their software: Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers? for example, if your customers/ competitors from the market reveal technology/secrets that you used in your solution (as LGPL requires that you make a Dynamic Link (.DLL) for your libs and you clearly tell the use of a Lib/Framework ...). Full story: For my project, I used a framework LGPL/commercial (Dual License) the second one it was too expensive (about 3000 USD) which pushed me to use LGPL.. however I still concerned.. That is why I ask for advise and especially motivations... Please do not hesitate to participate... Thanks in advance.

  • How mature is FreeBASIC?

    - by David
    A friend of mine is considering using FreeBASIC in a critical production environment. They currently use GWBasic, and they want to make a soft transition towards more modern languages. I am just worried that there might be undetected bugs in the software. I see that their version number is 0.22.0, which indicates, that it is not quite mature yet. I also read this discussion, without being able to conclude. Also on their Sourceforge pages there is no indication of whether it is Alpha or Beta (which anyways is not a very good indicator). Does anyone have own experience about the maturity, ideas on how to judge the maturity, or know of companies using FreeBASIC in a critical production environment?

  • Waiting for Windows 8: A Long, Hot Summer

    - by andrewbrust
    Microsoft has revealed some things about Windows 8, and revealed a part of the developer story for new Windows 8 “tailored,” “immersive” applications.  In retrospect, very little was shared.  The bit that was revealed to us is that those applications can be developed using a combination of HTML 5 and JavaScript.  Not much else was said, except that additional details would be revealed at Microsoft’s //Build/ conference in Anaheim, California in September. This has left a lot of people in suspense, and it seems that suspended state is going to last all summer.  The problem, of course, is that in the absence of hard information, people fill the void with Speculation, Rumor and Gloom.  That’s a bit like Fear, Uncertainty and Doubt, except that it’s self-imposed by the Microsoft community and not planted by Microsoft’s competitors. This is a less-than-perfect situation.  Not only is it causing developers to worry about the value of their skill sets, but I am already hearing from consulting shops that customers are getting nervous too and, in extreme cases, opting for non-Microsoft tools for their projects as a result.  I’m also hearing from dev tool ISVs that sales have suffered as a result. It’s quite possible that the customers moving off .NET wanted to do so anyway and it’s also possible that dev tool ISVs are suffering slower sales this year due a slowed rate of economic recovery. Without hard information, tend to people interpret things negatively.  Actually, that’s the major point in all of this. While there is multitude of opinions about what the Windows 8 development platform will look like once fully revealed, there is an emerging consensus around one thing: it sure would help if Microsoft revealed more of its strategy…just enough to quash absurd rumors, stabilize the .NET ecosystem and get people to stay calm. We’ve had some reassurances thus far: there will be a Windows desktop mode; we’ll still have Windows Explorer, we’ll still run Office, we’ll still have a task bar, and all the skills and tools we use now will still work there.  But with reassurances like that…people still feel insecure.  Because telling us that Windows 8 will have what is essentially a “classic” mode sure makes it sound like today’s skill sets will soon be “classic” too…and then maybe they’ll just become obsolete. Humans find change scary; it’s natural.  And when left alone with their fears – because no one is saying anything to dispel them – people can go from frightened to paranoid, and can start to viewing things in a downright conspiratorial light.  It would be great if Microsoft stepped into the void now and told us what is coming – especially because whatever they tell us is bound to be at least a little better than what people think they are going to hear. I don’t know what the announcements will be, but I do have it on authority, from a number of sources, that Microsoft isn’t gong to talk until //Build/.  That means no news until September September 13th.  Nothing until after Labor Day.  You get zippo until after the Back-to-School sales are done. What to do?  Try not to let the dark voices of gloom and doom fill your head.  Even in the absence of answers, we still have some important facts: The .NET developer community is huge. Microsoft’s customers have major investments in .NET, and in .NET skills. Political infighting in Redmond might make for irrational decisions, but ultimately public companies can’t just alienate their advocates and piss off their customers.  Spite doesn’t trump fiduciary responsibility. The computing device markets are changing, software is changing, software business models are changing and developers are changing.  Microsoft has to keep up. The HTML + JavaScript community is huge too, and it includes many of the “changed” developers. Public companies can’t ignore new markets nor the popular standards that can help them enter those new markets.  Loyalty doesn’t trump fiduciary responsibility either. If Microsoft can appeal to new developers, then it should. If Microsoft can keep catering to its existing developers and customers -- not just through legacy support, but also through empowering futures -- then it probably will. You don’t have to shove your old friends out into the rain to make room for new ones; you can bring those new constituents in under a bigger tent.  I hope Microsoft will enlarge the tent, and I have trouble imagining why it would not.

  • Passing data between engine layers

    - by spaceOwl
    I am building a software system (game engine with networking support ) that is made up of (roughly) these layers: Game Layer Messaging Layer Networking Layer Game related data is passed to the messaging layer (this could be anything that is game specific), where they are to be converted to network specific messages (which are then serialized to byte arrays). I'm looking for a way to be able to convert "game" data into "network" data, such that no strong coupling between these layers will exist. As it looks now, the Messaging layer sits between both layers (game and network) and "knows" both of them (it contains Converter objects that know how to translate between data objects of both layers back and forth). I am not sure this is the best solution. Is there a good design for passing objects between layers? I'd like to learn more about the different options.

  • How does a government development shop transition to developing open source solutions?

    - by Rob Oesch
    Our shop has identified several reasons why releasing our software solutions to the open source community would be a good idea. However, there are several reasons from a business stand point why converting our shop to open source would be questioned. I need help from anyone out there who has gone through this transition, or is in the process. Specifically a government entity. About our shop: - We develop and support web and client applications for the local law enforcement community. - We are NOT a private company, rather a public sector entity Some questions that tend to come about when we have this discussion are: We're a government agency, so isn't our code already public? How do we protect ourselves from being 'hacked' if someone looks into our code? (There are obvious answers to this question like making sure you don't hard code passwords, etc. However, the discussion needs to consider an audience of executives who are very security conscience.)

  • How do I get VirtualBox to work?

    - by Karasu
    I can't seem to make VirtualBox to work, I've installed it and reinstalled by 3 ways: Terminal, Ubuntu Software Center and VirtualBox's official web site installation and I keep getting the same kernel error. I found a "solution" to this problem by typing in terminal: sudo apt-get install virtualbox-dkms But it tells my that "virtualbox-dkms is already the newest version". Then I typed in terminal what the error tells me: sudo /etc/init.d/vboxdrv setup but then I tells me that DKMS is actually NOT installed (which is a contradiction). If anyone has encountered the same problem and actually solved it please tell me and explain me step by step 'cause I'm new to Linux.

  • How do you describe your profession in a public place or conference?

    - by Jenko
    I've often been in situations where non-technical people ask me, "So, what do you do?" ... and I've found it somewhat hard to describe that I spend the entirely of my days pouring over colored text. Of course, its quite reasonable to say "I design software" or "I develop computer applications", but that still feels somewhat "lame" and generic. So how do you describe your profession in public situations? are there any insights for those of us less gifted in public speaking?

  • Unrecognized Display

    - by Kevin
    I just installed a fresh copy of Ubuntu 12.04, and before I installed drivers, I was able to get my two monitor setup working just fine. However, after updating all my drivers and installing all the recommended software, my second display is no longer detected. My main display is called "Laptop" (which it was detected as the monitor name previously), but it is the only display listed. I tried to detect displays, nothing happened. The monitor is plugged in, and should be working fine - after all, it just was. How can I fix the problem of Ubuntu not listing my second monitor in the display settings?

  • Gmail Now Searches Inside PDF, Word, and PowerPoint Attachments

    - by Jason Fitzpatrick
    Gmail has long had a robust system for searching within the subjects and bodies of your emails, now you can search inside select attachments–PDF, Word, and PowerPoint attachments are all searchable. Prior to this update, Gmail could search inside of HTML attachments but lacked more advanced attachment querying abilities. Now when you search your Gmail account you’ll see search results for not only the subject and body contents but also the contents of popular formats like PDF and Word documents. Don’t forget to take advantage of advanced search terms to speed up your query. If you know the information you need is in an attachment but can’t remember which email, include “has:attachment” in your search to only peek inside emails with attachments.

  • Is it a bad idea to get a Master's and Bachelor's Degree from the same university?

    - by sahhhm
    I'm getting close to graduation and am strongly considering continuing to a Master's Program. My long-term goal for the future is to stay in industry rather than pursuing a Ph.D/Academic career. While communicating these thoughts with some of my peers, I've been told that staying in the same University for both a Bachelor's and Master's degree is ill-advisable. The reasons seem to be based along the lines of lack of exposure to other opportunities, programs, and faculty. My question is, if I intend to pursue a career outside of the Ph.D/Academic spectrum, will staying at the same university for my master's really decrease my value in software related positions? If so (or if not), why?

  • Why is 2^16 a "special" number?

    - by javamonkey79
    OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

  • Why is (Ogg) Vorbis not automatically supported by Windows?

    - by flying sheep
    Vorbis was never threatened by MPEG LA, so it is undoubtedly completely patent free. (MPEG LA never misses a chance to spread patent FUD) Windows supports mp3, so it isn’t because they want to push their crappy wma. The GPL allows distribution alongside commercial products, and Even if they fear to ship GPL software, they can still load it automatically, like they do with XviD So why can’t a windows customer not simply drop a ogg vorbis file into his/her music library and listen to it via WMP? PS: To counter misconceptions: They already download the GPL’d XviD codec on demand, so they already have 99% of what it takes to do the same with Vorbis. It would take me about 5 minutes to do this, if I were familiar with the WMP code base and directshow filter system. PSS: I was told to ask this here rather than on stackoverflow, so i do.

  • My system can't be updated

    - by Lucio
    After I installed some updates I restarted my computer. Some days later I wanted to check for updates because the update-manager shows me the following: "The packet information has been updated last 24 days ago." and a window appeared. That window after downloading packages, said that: Failed to download the information from the repository Check your Internet connection Details: W:Failed to fetch gzip:/var/lib/apt/lists/partial/ar.archive.ubuntu.com_ubuntu_dists_oneiric_unive??rse_i18n_Translation-en Encountered a section with no Package: header , E:Some index files failed to download. They have been ignored, or old ones used instead. But my Internet connection works fine. I downloaded and installed and run the banish404 software and it does not work. Also I tried with an terminal with 'sudo apt-get update'. What do I have to do?

  • Finding a good University [closed]

    - by Liamh101
    I've currently been searching for good Universities to study Software Engineering or Computer Science at. The three Universities I've chosen so far are: Brighton University (This is my main pick so far) Plymouth Uni Manchester Metropolitan I would just like to know from people who have actually studied at these places to see if there all that there cracked up to be and I'm not going to be wasting up to four years of my life with a course that isn't very well taught. Would love to hear from people and if there are any Universities in the UK that you are/have studied at and are finding really good for learning Programming that would be nice too. Thanks!

  • Play videos with libwebkit in Ubuntu 11.10 server

    - by Luis Fagundes
    I'm using libwebkit (with python-webkit) to render a page that plays a video. This application works fine in a Ubuntu 11.04 Desktop, Nvidia card and lots of libraries and software installed, but in a fresh Ubuntu 11.10 Server with intel 82945G/GZ card the video does not play. I guess either some codec package is missing or it's a driver problem. What could be missing for this to play? I'm trying with this video: http://video.eustasy.co.uk/480/ EDIT: doesn't look like a driver problem. With chromium I can play the video, but with libwebkit + python-webkit the video just shows the first frame and doesn't play. Any hints on what package could be missing? SOLVED: apparently it had to do with lack of audio. While chrome would play the video with no sound, libwebkit wouldn't start video. Adding user to audio and video groups solved the problem.

  • What significant progress have we made in Rapid Application Development?

    - by Frank Computer
    Since the introduction of OOPL's and event-driven programming, I feel like developing an application has become harder and more tedious, when it should have been the other way around! We should have development tools which can generate prototype apps which can be quickly and easily customized into sophisticated applications, even by novice users! We really need new ideas in this area of software development and I would like to know of any good ideas. If we can't really find them, then we should ask "Where did we miss the boat?.. Why?.. and What should we be doing?"

  • Options for Opensource license?

    - by foodil
    I am choosing a license for my open source software and I've learned about GPL, EBMS and BSD. GPL seems to be most popular one. The problems are: Would anybody kindly name a few popular opensource licenses? Since I do not see any EBMS BSD license is popular. Are there any chart or table that have list out the advantages/disadvantages of using anyone? Why is the GPL always the license developers choose from, what are its benefits? Thank you.

  • We Heart Discussion Forums (and Know You Do Too)

    - by oracletechnet
    It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!
