  • Can't install php5 on Ubuntu

    - by Itay Moav
    I try to apt-get install php5 I get: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

  • PHP accessible shared content between two websites on the same VPS on different domains/IPs

    - by Lee Fentress
    I have two ecommerce websites, selling music digital downloads, on the same VPS, currently using cPanel/WHM (but thinking of switching to Virtualmin). They have separate domains and IPs of course. They both share from the same set of music files, so I have duplicate copies in each website directory, which takes up a lot of disk space. How might I go about sharing the same set of music files across both sites, allowing PHP access, so that it does not break my shopping cart's functionality of serving customers the downloads after they have paid for them? I thought of maybe using symlinks or something, but I don't know if it's possible, or if it would have to somehow circumvent built-in security features of the server. I'm new to VPS management.

  • ifconfig not showing all IPs bound to the machine

    - by pankaj sharma
    I have configured multiple IP addresses on a ubuntu box, but when I run ifconfig it shows just one of them. I am able, however, to ping all other adresses assigned to this machine. /etc/network/interface contents: # This file describes the network interfaces available on your system # and how to activate them.

  • downgrade ppa packages to versions available at a previous point in time

    - by Will
    The backstory is that the normal Intel GPU drivers don't do the various OpenGL extensions that my hobby coding and some games want. So I have to install xorg-edgers and then its happy. However, last Wednesday or so there was an update to xorg-edgers - lots of packages - and it broke badly; the drivers lock up and take the whole computer with them; hard reset required. So how can you downgrade - select package versions in a PPA that represent a point in the past, ignoring versions newer than that?

  • Why does the HUD jump around as I type or move my mouse?

    - by Ryan McClure
    I use the Unity Revamped package for my Unity interface. I have noticed that, however, this behavior exists for any account on my computer, even guest, on BOTH the Revamped and the Canonical release of Unity. Here is a link to what it looks like, because it is hard to describe it. I don't know of anyone else who has this issue. I am running Unity 5.16 on Ubuntu 12.04. As an aside, I also have noticed this behavior with a fresh install of 12.10 Beta 1 on a separate partition.

  • How to import a pdf in libreoffice? under ubuntu, all pages are blank

    - by Daniele
    I have some .pdf generated by a scanner, that I want to import in LibreOffice and do some small editing. The PDF has only one object per page, a page-size image. If I open it in LibreOffice under Ubuntu 12.10, it imports "successfully" but all pages are blank. I have the libreoffice-pdfimport package installed. That is true with both LibreOffice 3.6 (part of Ubuntu 12.10) and with 4.0.2, from libreoffice ppa. The same .pdf files open perfectly fine on both LibreOffice for Windows and LibreOffice for Mac (yes, I have three computers with all three OSes), but on Ubuntu 12.10, all pages are blank, so I can only conclude this is an issue with Ubuntu packaging, or something really weird prevents it from working under linux. How can I import these kinds of .pdf into LibreOffice for editing?

  • Is Domain Driven Design useful / productive for not so complex domains?

    - by Elijah
    When assessing a potential project at work, I suggested that it might be advantageous to use a domain driven design approach to its object model. The project does not have an excessively complex domain, so my coworker threw this at me: It has been said, that DDD is favorable in instances where there is a complex domain model (“...It applies whenever we are operating in a complex, intricate domain” Eric Evans). What I'm lost on is - how you define the complexity of a domain? Can it be defined by the number of aggregate roots in the domain model? Is the complexity of a domain in the interaction of objects? The domain that we are assessing is related online publishing and content management.

  • An error when installing MVVM Light templates for VS10 Express

    - by Laurent Bugnion
    If you tried to install the Visual Studio 2010 Express project and item templates of MVVM Light V3 SP1 (with the Windows Phone tools hotfix), you may have encountered an error when unzipping the package, telling you that a file was corrupted. This error was reported to me a couple of times, and I was able to reproduce the issue. I just published a new version that takes care of this issue. If you encountered that error when installing, please download the new version and try again. Note that the error was only there for the Visual Studio 2010 Express version of the templates. No other changes were made.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Transactional Interceptors in Java EE 7 - Request for feedback

    - by arungupta
    Linda described how EJB's container-managed transactions can be applied to the Java EE 7 platform as a whole using a solution based on CDI interceptors. This can then be used by other Java EE components as well, such as Managed Beans. The plan is to add an annotation and standardized values in the javax.transaction package. For example: @Inherited @InterceptorBinding @Target({TYPE, METHOD}) @Retention(RUNTIME) public @interface Transactional { TxType value() default TxType.REQUIRED } And then this can be specified on a class or a method of a class as: public class ShoppingCart { ... @Transactional public void checkOut() {...} ... } This interceptor will be defined as part of the update to Java Transactions API spec at jta-spec.java.net. The Java EE 7 Expert Group needs your help and looking for feedback on the exact semantics. The complete discussion can be read here. Please post your feedback to [email protected] and we'll also consider comments posted to this entry.

  • ADF Business Components

    - by Arda Eralp
    ADF Business Components and JDeveloper simplify the development, delivery, and customization of business applications for the Java EE platform. With ADF Business Components, developers aren't required to write the application infrastructure code required by the typical Java EE application to: Connect to the database Retrieve data Lock database records Manage transactions   ADF Business Components addresses these tasks through its library of reusable software components and through the supporting design time facilities in JDeveloper. Most importantly, developers save time using ADF Business Components since the JDeveloper design time makes typical development tasks entirely declarative. In particular, JDeveloper supports declarative development with ADF Business Components to: Author and test business logic in components which automatically integrate with databases Reuse business logic through multiple SQL-based views of data, supporting different application tasks Access and update the views from browser, desktop, mobile, and web service clients Customize application functionality in layers without requiring modification of the delivered application The goal of ADF Business Components is to make the business services developer more productive.   ADF Business Components provides a foundation of Java classes that allow your business-tier application components to leverage the functionality provided in the following areas: Simplifying Data Access Design a data model for client displays, including only necessary data Include master-detail hierarchies of any complexity as part of the data model Implement end-user Query-by-Example data filtering without code Automatically coordinate data model changes with business services layer Automatically validate and save any changes to the database   Enforcing Business Domain Validation and Business Logic Declaratively enforce required fields, primary key uniqueness, data precision-scale, and foreign key references Easily capture and enforce both simple and complex business rules, programmatically or declaratively, with multilevel validation support Navigate relationships between business domain objects and enforce constraints related to compound components   Supporting Sophisticated UIs with Multipage Units of Work Automatically reflect changes made by business service application logic in the user interface Retrieve reference information from related tables, and automatically maintain the information when the user changes foreign-key values Simplify multistep web-based business transactions with automatic web-tier state management Handle images, video, sound, and documents without having to use code Synchronize pending data changes across multiple views of data Consistently apply prompts, tooltips, format masks, and error messages in any application Define custom metadata for any business components to support metadata-driven user interface or application functionality Add dynamic attributes at runtime to simplify per-row state management   Implementing High-Performance Service-Oriented Architecture Support highly functional web service interfaces for business integration without writing code Enforce best-practice interface-based programming style Simplify application security with automatic JAAS integration and audit maintenance "Write once, run anywhere": use the same business service as plain Java class, EJB session bean, or web service   Streamlining Application Customization Extend component functionality after delivery without modifying source code Globally substitute delivered components with extended ones without modifying the application   ADF Business Components implements the business service through the following set of cooperating components: Entity object An entity object represents a row in a database table and simplifies modifying its data by handling all data manipulation language (DML) operations for you. These are basically your 1 to 1 representation of a database table. Each table in the database will have 1 and only 1 EO. The EO contains the mapping between columns and attributes. EO's also contain the business logic and validation. These are you core data services. They are responsible for updating, inserting and deleting records. The Attributes tab displays the actual mapping between attributes and columns, the mapping has following fields: Name : contains the name of the attribute we expose in our data model. Type : defines the data type of the attribute in our application. Column : specifies the column to which we want to map the attribute with Column Type : contains the type of the column in the database   View object A view object represents a SQL query. You use the full power of the familiar SQL language to join, filter, sort, and aggregate data into exactly the shape required by the end-user task. The attributes in the View Objects are actually coming from the Entity Object. In the end the VO will generate a query but you basically build a VO by selecting which EO need to participate in the VO and which attributes of those EO you want to use. That's why you have the Entity Usage column so you can see the relation between VO and EO. In the query tab you can clearly see the query that will be generated for the VO. At this stage we don't need it and just use it for information purpose. In later stages we might use it. Application module An application module is the controller of your data layer. It is responsible for keeping hold of the transaction. It exposes the data model to the view layer. You expose the VO's through the Application Module. This is the abstraction of your data layer which you want to show to the outside word.It defines an updatable data model and top-level procedures and functions (called service methods) related to a logical unit of work related to an end-user task. While the base components handle all the common cases through built-in behavior, customization is always possible and the default behavior provided by the base components can be easily overridden or augmented. When you create EO's, a foreign key will be translated into an association in our model. It defines the type of relation and who is the master and child as well as how the visibility of the association looks like. A similar concept exists to identify relations between view objects. These are called view links. These are almost identical as association except that a view link is based upon attributes defined in the view object. It can also be based upon an association. Here's a short summary: Entity Objects: representations of tables Association: Relations between EO's. Representations of foreign keys View Objects: Logical model View Links: Relationships between view objects Application Model: interface to your application

  • Alps touchpad detected as mouse dell inspiron n5110

    - by Shota Bakuradze

  • Skype on Ubuntu 12.04 x64 - anyone has it installed?

    - by Zevaka
    I am wondering if there's anyone here who managed to use skype @ 12.04. It used to work (ever since i first tried Ubuntu 10.04) flawlessly, but after upgrade to 12.04 just doesn't start. If I start skype from terminal, it just says "Segmentation fault (core dumped). I tried to remove skype and installed it from different locations: Skype website (did not install at all, "package error") From official Ubuntu repository (doesn't start at all, segmentation fault) From repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" (doesn't start at all, segmentation fault) Interesting thing: even if I remove / purge skype from the system, it still shows up in Unity menu (of course doesn't start). Any help here? Thanks!

  • Bitbucket and a small development house

    - by Marlon
    I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of shared folders! In the process of rolling this out, I am thinking of different strategies to manage our stuff and I am leaning towards using Bitbucket as our "central" repository. The projects in Bitbucket will solely be private projects and everyone will push and pull from there. I am open to different suggestions, but has anyone got a similar setup? If so, what caveats have you encountered?

  • Is slower performance, of programming languages, really, a bad thing?

    - by Emanuil
    Here's how I see it. There's machine code and it's all that computers needs in order to run something. Computers don't care about programming languages. It doesn't matter to them whether the machine code comes from Perl, Python or PHP. Programming languages don't serve computers. They serve programmers. Some programming languages run slower than others but that's not necessarily because there is something wrong with them. In many cases, it's because they do more things that programmers would otherwise have to do (i.e. memory management) and by doing these things, they are better in what they are supposed to do - serve programmers. So, is slower performance, of programming languages, really, a bad thing?

  • CS, SE, HCI, Information Science, Please recommendation for further education of the former performing art manager seeking career in IT industries? [on hold]

    - by Baek Seungjoo
    IT specialists there J Thank you very much for your collective efforts here, and I got huge help reading your professional comments and advices on each questions I have searched so far! This time, I would like to ask for your practical advices or recommendation on what I am struggling on at this moment. I am currently seeking higher education for my career transition from performing art manager and director to “IT software and/or service development and management specialist”. However, as this field is quite new to me, and there are lots of different work positions, I have no idea which grad major I better pursue in order to get qualification. Of course I know this question could sounds wired as it is kind of personal choice. But my lack of understanding on how IT software companies work in general, your practical and experience-based advice will be great help to me, who spent more than two months of self-research on net. OK. Before my question, here is my plan and history, which are quite different from those currently in IT industry I think… 1) Target Firstly, get career transition into IT service or products companies and get experiences. Eventually, pursue IT entrepreneurship in combination with my arts and cultural production and business expertise. 2) Background Career: performing arts director and manager in theatre-based scale opera and musical Art education in youth BA in literature and Chinese studies (Art & Humanities) MA in Cultural & Creative Industries (Art & Humanities) – dissertation with focus on digital prosumption and the lived experience of the prosumer. (a qualitative research on the agents in the digital world) 2) Personally Huge interest in IT hardware and software, and their trend. Skills to build up, repair, tune PCs -of course this is no more than personal hobby, but shows my interests in this field. 4) Problem Encounter a question “So, what do you think you can contribute practically in this position”. This question turn me down everytime I go through job interviews, and I decided more education in the relevant area. Here are my questions. 1) In terms of work positions in IT software companies, I wonder if I can put the comparison of what “Artists” is to “Arts Manager or Director” is what “Developer” is to “Product Manager”. (Of course, this stereotypical division of Artist-Art Manager is out of sense because the domain overlaps to some extent, and is blurring at least in my field, and they are in different contexts, but just speaking easily.) Normally, artist comes with special arts educations, and they live in their own world of artistic inspiration and creation, and they feel alive in practice and on stages. Meanwhile, from the point of staging and managing productions, the role of art manager is critical as well. Our role cares how the production appeals to the audience in effective way, how to make profit and future sustainable management through that, how to set up future strategy in consideration of the external conditions such as political and social circumstances, audience trend and level, other production trends from on-going and historical perspectives, how and what the production make voice to the society from political, economic, humanitarian stances. So, we need keen eyes on economic, political, and societal environment, have to understand human-being and their desires, must know how to make presentation and attract investors, must have sense in managing and fighting over the limited financial resource, how to extend networking and so on. It is common that the two agents create productions in collaboration (normally not in that ideal way but in conflict and fight though J ). So, we need to know each other’s expertise to some extent, for better production. What are the work positions in IT software industries equivalent to the role of “art manager” in performing arts? From my view, considering developers come with special education in the world of computer science, software engineering, or others (self-education sometimes), and they express themselves with the arts of coding, computer languages on the black screen, and make sort of their artistic production online to the audience, I guess there might be someone who collaborate with developers in creating, managing, and launching IT services or products. 2) Which education among CS, SE, HCI, Information Science, is needed for those seeking such work position? Especially for person like me. (At this moment, Information Science has the highest possibility to get in, since I lack Calculus and Math in undergrad educaiton. But please let me know irrespective of this concern, I think there are ways to back it up if CS or SE education needed in my case) 3) Which field between Information Science and HCI can be more practical background regarding job hungting? And which of them have more demands in job market? AS I checked, HCI is more close to CS than IS in its focus of study area. Thank you very much for your patience reading such a long inquiry, and I appreciate to your efforts in advance. Have a nice day in this beautiful summer.

  • migrating product and team from startup race to quality development

    - by thevikas
    This is year 3 and product is selling good enough. Now we need to enforce good software development practices. The goal is to monitor incoming bug reports and reduce them, allow never ending features and get ready for scaling 10x. The phrases "test-driven-development" and "continuous-integration" are not even understood by the team cause they were all in the first 2 year product race. Tech team size is 5. The question is how to sell/convince team and management about TDD/unit testing/coding standards/documentation - with economics. train the team to do more than just feature coding and start writing test units along - which looks like more work, means needs more time! how to plan for creating units for all backlog production code

  • How do I give proper attribution when distributing my modified Ambiance theme?

    - by WarriorIng64
    I made a modified version of 12.04's Ambiance that uses a dark sidebar for Nautilus, and I would like to redistribute it via e.g. gnome-look.org. From the Launchpad page for the light-themes package, it says the themes are available under a Creative Commons BY-SA 3.0 license. The way I understand it, I can distribute my modified theme so long as I provide proper attribution for it and place it under the same license. In this case, who do I attribute as the author of the original theme and where/how should I display this attribution?

  • Lead/Manager vs Individual contributor which is better?

    - by User11091981
    Currently I am working in a company as a Manager (software dev). But I only have 6.8 yrs experience. I joined this company as a software engineer and got promoted to SSE, Lead and Manager. Some of my team members are having better experience than me, and I feel like I need to have more exposure/experience to take these roles. I feel like it is better to be an individual contributor learn many things for another couple of years and become a Principal Software Engineer, rather than involving in Management. Options I have: 1. Ask my current employer to make me an individual contributor? 2. Find a new company and join as an SSE to start over? 3. Find a new company for a lead position? Please advice.

  • Offline apt-get update to age of cache

    - by James Haigh
    I have a script to quickly upgrade a Live or fresh system from cached files on a flash drive. In essence, it looks like this: # *Code to remove and symlink /var/cache/apt/ if currently empty of packages.* sudo apt-get dist-upgrade # Quick offline cached upgrade; not limited by slow WANs. echo $'\nMake sure Internet is reachable and press enter for complete online upgrade.'; read sudo apt-get update sudo apt-get dist-upgrade # Complete online upgrade. The problem is that the ‘cached upgrade’ seems to ignore the cached pkgcache.bin and srcpkgcache.bin which is where I assume apt-get update stores its changes, so the upgrade completes as if the system is up-to-date. Useless. So in that case, I need some code to apt-get update to the age of the package cache on my flash drive. This code would be placed between the 1st and 2nd lines of the code above.
