    - by Stoney_Fish
    Ubuntu 14.04 64bit on Dell E6420 (Sandybridge graphics) Open Unity Dash search My filters are set only on "Applications" and "Files & Folders" I type : Software The results are good but some icons appear as blank page icons (document?) Example Applications : "Ubuntu Software Centre" and "Software & Updates" "Software Updater" has the correct application icon. (The blank page icon look like a blank page with the top right corner folded.)

  • Installing device drivers as part of VS2008 setup application (3 replies)

    A colleague in another department has produced device drivers for some USB devices that I need to communicate with in my VS2008 .Net application, and I'm looking to simplify the installation experience for our users. Currently I just put the driver files onto the CD in a folder, and the Windows Add Hardware Wizard will usually take them through the process. What I would like to do though, is to in...

  • PHP Web Application Development - The Value of Smart Planning in Development

    If you've outsourced web application development, or worked as a programmer or project leader of development team, you've definitely experienced the difficult strive towards meeting a deadline. Time always seems to be a constraint. The client may bring up changes which he or she feels should have been understood by the development team (sometimes rightfully and other times not) which further puts pressure on the team to deliver faster than what they may be able to. At least without proper planning that is.

  • web application load / stress testing services

    - by Booji Boy
    Can you recommend reputable companies that offer help (consulting services, etc) in load testing (ASP.NET) web applications? We have a client looking to load test an ASP.NET application and we don't have any expertise in load testing web applications. The client is located in central Massachusetts. My employer http://www.goADNET.com was looking for an option besides, “I can figure out how to do it”.

  • GPL vs plugin interfaces not designed with a specific application in mind

    - by Kristóf Marussy
    I am not seeking or in need of legal advice, but an interesting though experiment came to my mind. Imagine the following situtation (I cannot really think about a concrete example and I am unsure if a real manifestation even exists): there is a free (libre) api A licensed under some permissive license or even LGPL. Non-free application B implements this api in order host plugins, but there are other free software doing the same thing. Moreover, there is plugin C acting as a plugin under api A. It links to library D, that is under GPL, so C is also under GPL. Plugins using A are loaded into hosts via a dlopen-like mechanism and use complex data structure for host-plugin communication. Neither B nor C distribute any files that may be required for A to function properly (like headers containing the structure definitions of A or dynamic libraries containing helper functions for A written by the authors of A), but such things may exist. Now some user installs application B and plugin C on his machine, along with anything that may be required for api A to function properly. Then he proceeds and loads C into B and creates some intellectual property with B which is not a piece of software. Did a GPL violation happend at some point, and if so, who violated GPL and why? The authors of C violate D's license by making C possible to be used in non-free host B? This is a possibility because they can't give and exception of GPL (like one described in http://www.gnu.org/licenses/gpl-faq.html#GPLPluginsInNF or http://www.gnu.org/licenses/gpl-faq.html#LinkingOverControlledInterface) due to D's license terms. The authors of B violate C's and D's license by making C possible to be loaded in B? This is a possibility because http://www.gnu.org/licenses/gpl-faq.html#NFUseGPLPlugins disallows the mechanisms A uses for communitation between the free and non-free modules. The authors of A, because the api may be used (and in this case, was used) for communication between GPL'd and non-free software. This would be extremely absurd. The user, because at the moment of loading B into C, he made a derived work of C. I think this is impossible, because he does not distribute it. But would the situation change is he decided to release a configuration file of B which makes B load C as a plugin? Nobody, because A counts as a 'system library', and both B and C directly interact only with A, not eachother. In a sane world, this would happen... A concrete example of A could be some kind of audio (think LADSPA) or image processing api. However, I could find no such interface (that is free software, generic and is also implemented by commercial tools). A real-world example could also be quite enlightening.

  • Suggestion for an application to do our company car fleet management

    - by Pitto
    (As suggested I've tried asking on webapps with no luck... So I try on askubuntu: I'll be luckier :) ) Hello, everybody! Our company could be a little more open source and a little "ubuntier" if I can find an easy and user friendly web application (we already have our LAMP server based on Ubuntu 10.04 LTS) to handle company's car fleet expenses and repairs planning. Any hints? :) Thanks for any kind of help.

  • Notifying a separate application of an event

    - by TomDestry
    I have an application that runs through various tasks as an automated process. My client would like me to create a file in a given folder for each task as a way to flag when each task completes. They prefer this to a database flag because they can be notified by the file system rather than continually polling a database table. I can do this but creating and deleting files as flags feels clunky. Is there a more elegant approach to notifying a third-party of an event?

  • Online Application Upgrade

    - by lsarecz
    Amikor HA (High Availability - Magas Rendelkezésre Állás) megoldásokról beszélünk, általában elsoként a klaszterek, redundáns megoldások jutnak eszünkbe. Pedig nem csak a hardver hibákra kell gondolni, hanem a tervezett leállásokkal is érdemes foglalkozni. Az egyik talán legkevésbé megoldott probléma az, ha egy alkalmazás verzió váltást kell végrehajtani úgy, hogy közben változik az adatstruktúra is. Ez nyilván azt eredményezi, hogy le kell állítani az adatbázist is, és az átszervezéseket, akár adat átalakításokkal együtt végre kell hajtani. De a legnagyobb probléma talán az, hogy amennyiben valami rosszul sül el, és vissza kell állni a kiinduló állapotra, akkor az adatbázis mentést is vissza kell tölteni, hiszen átmenetileg minden felhasználó aki épp használatba vette az új alkalmazás verziót már egy új adatstruktúrába kezdett dolgozni. Az Oracle Database Online Application Upgrade képessége, vagy pontosabb nevén az Edition Based Redefinition pontosan ezt a problémát célozza meg. Az Edition Based Redefinition 3 alap objektummal muködik, ezek: edition, editioning view és crossedition trigger. Az edition egy új nonschema objektum típus. 11gR2 verziótól minden adatbázis rendelkezik legalább egy edition-nel, melynek neve Ora$Base. Minden új edition egy már létezo gyermeke kell, hogy legyen. Amikor kapcsolódunk az adatbázishoz, meghatározható, hogy melyik edition-höz kapcsolódjunk. Kizárólag nézetek, szinonímák és PL/SQL ojektum típusoknak lehet több edíciója (ezek metadat típusú objektumok, nem tartalmaznak adatokat). Azok az objektumok, melyek több edícióval rendelkeznek egyedileg csak úgy azonosíthatók, ha az owner, name, namespace mellett az edition-t is megnevezzük. Azaz két vagy több példánya is létezhet egy adatbázison belül ugyanazzal az owner, name és namespace azonosítókkal rendelkezo objektumnak, amennyiben használjuk az edition-based redefinition-t. Egy új objektum típus, az editioning view is edicionálható. Mivel a fizikai tábla nem edicionálható (elkerülendo az adatok többszörös tárolását és teljesítmény gondokat), ezért az editioning view feladata egy adott tábla egyszeru leképezése egy nézet formájában, ami már több edition-ben is létezhet, és képes elfedni a tábla módosításait. Amennyiben a tábla módosítások olyan táblákat érintenek, amelyek tartalmát  az alkalmazás felhasználók módosítják, szükség van olyan triggerekre, amelyek az egyes editioning view-k között a módosításokat karbantartják. Ezek a crossedition triggerek. Természetesen ahhoz, hogy az online application upgrade muködjön, minden érintett tábla elé el kell készíteni az editioning nézetet és a megfelelo crossedition triggereket. Ezeket használva az alkalmazás két vagy több különbözo verzió képes ugyanazon adatbázison párhuzamosan futni, és ha megtörtént a verzióváltás, akkor még mindig egyszeru visszaállni a régi verzióra egészen addig, amíg a régi edition eldobásra nem kerül. További információk az Edition-Based Redefinition címu whitepaper-ben találhatók.

  • Slow in the Application but Fast in SQL Server Management Studio - from Erland

    - by Greg Low
    Our MVP buddy Erland Sommarskog doesn't post articles that often but when he does, you should read them. His latest post is here: http://www.sommarskog.se/query-plan-mysteries.html It talks about why a query might be slow when sent from an application but fast when you execute it in SSMS. But it covers way more than that. There is a great deal of good info on how queries are executed and query plans generated. Highly recommended!...(read more)

  • Tomcat Manager Application and HTTP 404 Error

    - by David
    I am trying to set up the admin application for a Tomcat 6.0.24 instance. None of the searches I've done turn up anything I can use. I am using this configuration for Apache 2.2.14: Alias /manager /usr/share/tomcat6-admin/manager <Directory "/usr/share/tomcat6-admin/manager"> Options Indexes FollowSymLinks AllowOverride None allow from all </Directory> ProxyPass /manager ajp://localhost:8009/manager In the tomcat-users.xml I have this: <tomcat-users> <role rolename="tomcat"/> <role rolename="admin"/> <role rolename="operator"/> <role rolename="manager"/> <user username="admin" password="nopasswordforyou" roles="admin,tomcat,manager"/> <user username="operator" password="nevermind" roles="operator"/> </tomcat-users> I found the docs that suggested I needed manager-gui role installed and defined, but that appears to be Tomcat 7, not Tomcat 6. The manager.xml is the default provided with Ubuntu Lucid Lynx 10.04: <Context path="/manager" docBase="/usr/share/tomcat6-admin/manager" antiResourceLocking="false" privileged="true" /> If I access /manager from a web browser, I get a 404 error from Tomcat: "requested resource not available." If I access /manager/images I get the same thing. If I access /manager/401.jsp I get the actual page. In addition, the server.xml has not only the usual Realm (UserDatabaseRealm) but also one for MySQL authentication (JDBCRealm). Investigating this showed that the role of manager was not present there for the user admin; I fixed that by doing: INSERT USER_ROLE_DB SET USER_NAME='admin', ROLE_NAME='manager'; I restarted Tomcat, although I suspect that was overkill. No change. I don't see any errors in catalina.out or in localhost.* log files. What am I missing? What is the interaction between the different realms? How do I get the manager application working?

  • Start with open source desktop application and move to iPhone/Android app

    - by user92356
    I'm a high schooler and I am competing in an open source software development competition. It must be a desktop application that runs on either Windows or Linux. I have a great idea for the open source desktop app, and I wanted to know if I could take it farther and port it to the iPhone or Android platform and make money (preferably through $.99 cost, not ads) I read somewhere that certain open source licenses allow me to do this... am I correct?
