• Ubuntu 12.04 LTS can't add Cheese widget

  - by Burke Hodgson

  Command-line 12.04 Cheese (cheese:4144): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkToggleButton, but as a GtkBin subclass a GtkToggleButton can only contain one widget at a time; it already contains a widget of type GtkLabel Is there a fix so that Cheese will work in Ubuntu 12.04? The program comes up but the webcam area is black. I am running Unity 2D on a T42 Thinkpad. All programs similar to Cheese recognize my webcam as does Skype, but I really like Cheese and the error message may be ominous for other software failures.

• Performance-Based Management Stinks

  - by andyleonard

  Introduction This post is the forty-eighth part of a ramble-rant about the software business. The current posts in this series can be found on the series landing page . This post is about Performance-Based Management (PBM). Almost… In Mere Christianity , C. S. Lewis refutes an argument with the following statement: It has every amiable quality except that of being useful. I feel the same way about PBM. I am a metrics person. I thrive – intellectually, emotionally, and economically – on business intelligence...(read more)

• How to act when you get the last warning? [closed]

  - by Cody

  I'm a software developer, currently working on web development. We are a small company a team with 2 persons, a developer and a designer and we have no-one to test our applications. From the last week I was somehow rushed to finish a task within a project programmed by someone else and I released it with a bug which I did not see. Today I got the last warning and if there is a release with a bug I will be fired. So is this fair enough to get fired because releases with bugs without any testers around or should I really improve my skills on testing?

• Identifying the best pattern

  - by Daniel Grillo

  I'm developing a software to program a device. I have some commands like Reset, Read_Version, Read_memory, Write_memory, Erase_memory. Reset and Read_Version are fixed. They don't need parameters. Read_memory and Erase_memory need the same parameters that are Length and Address. Write_memory needs Lenght, Address and Data. For each command, I have the same steps in sequence, that are something like this sendCommand, waitForResponse, treatResponse. I'm having difficulty to identify which pattern should I use. Factory, Template Method, Strategy or other pattern.

• Whats the best CMS for Sports Club? [closed]

  - by René

  Possible Duplicate: What Forum Software should I use? I have to renew a website for a sport club. There is some self programmed CMS in use at this time. But I need a new solution. A popular CMS that could be up to date over the next 3 or 4 years. I took a look at Drupal 7. Not sure about whether it's easy possible to create member profiles (they should be able to edit them self), a board and team overviews. Would be cool you'll share the link of a tutorial for this needs if you have one. Or... Any suggestions for a good CMS with my needs?

• Why does F. Wagner consider "NOT (AI_LARGER_THAN_8.1)" to be ambiguous?

  - by oosterwal

  In his article on Virtual Environments (a part of his VFSM specification method) Ferdinand Wagner describes some new ways of thinking about Boolean Algebra as a software design tool. On page 4 of this PDF article, when describing operators in his system he says this: Control statements need Boolean values. Hence, the names must be used to produce Boolean results. To achieve this we want to combine them together using Boolean operators. There is nothing wrong with usage of AND and OR operators with their Boolean meaning. For instance, we may write: DI_ON OR AI_LARGER_THAN_8.1 AND TIMER_OVER to express the control situation: digital input is on or analog input is larger than 8.1 and timer is over. We cannot use the NOT operator, because the result of the Boolean negation makes sense only for true Boolean values. The result of, for instance, NOT (AI_LARGER_THAN_8.1) would be ambiguous. If "AI_LARGER_THAN_8.1" is acceptable, why would he consider "NOT (AI_LARGER_THAN_8.1)" to be ambiguous?

• How to control an Ubuntu PC from another Ubuntu PC over Internet?

  - by Naveen

  There are two Ubuntu PCs called A and B. A and B are connected to the Internet using two separated Internet connections. (In my case, two mobile broadband connections ppp0 x2 ) Each connection has a unique & static public IP address. What I need is to control A computer's cursor, using B computer's mouse, over the Internet. In both computers, I have allowed other users to control my computer in Desktop Sharing preferences, as below: When I try to connect to A from the B using Remmina Remote Desktop Client, it refuses to connect after trying for a while. These are my settings: I expect this to be done from an available open source software, not from TeamViewer. I found this guide harder to understand. Please provide me clear instructions... Thanks for having a look!

• Real life example of an agile game development process

  - by Ken

  I'm trying to learn about applying agile methodologies to game development. But seems to be impossible to find real life examples. What I am looking for are things like; Initial user stories Final user stories (complete, covering the entire game requirements) Acceptance criteria Task list Sprint backlogs (before and after each sprint) The agile books seem to have some limited examples, many of which seem contrived. In this era of open source software, there must be an documented example of the process applied to a game that is publicly available. I am asking specifically about games because they are so different from normal applications. Regular applications are built to all users to complete specific tasks in order to get stuff done(book a room, print a report etc). People play games for much less tangible reasons, so I think the process is significantly different. [it doesn't have to be scrum, it could be any process, just needs to be a real life example game and be reasonably complete]

• Is there a real difference between dynamic analysis and testing?

  - by user970696

  Often testing is regarded as a dynamic analysis of a software. Yet while writing my thesis, the reviewer noted to me that dynamic analysis is about analyzing the program behind the scenes - e.g. profiling and that it is not the same as testing because its "analysis" which looks inside and observes. I know that "static analysis" is not testing, should we then separate this "dynamic analysis" also from testing? Some books do refer to dynamic analysis in this sense. I would maybe say that testing is a one mean of dynamic analysis?

• Nginx and automatic updates

  - by Desmond Hume

  I'm on Ubuntu 12.04.1 with unattended-upgrades configured for automatic security updates, and I installed Nginx by first adding deb http://nginx.org/packages/ubuntu/ lucid nginx deb-src http://nginx.org/packages/ubuntu/ lucid nginx to /etc/apt/sources.list file, just as was suggested by the official wiki, and then by sudo apt-get update sudo apt-get install nginx which installed Nginx with all the standard modules. But now I think I could make good use of one or two of the Nginx optional modules, like the gzip precompression module or some security-related one. So far, I see two ways of adding an optional module to Nginx, one is compiling and installing from the source code and the other is described in this article. So, which of the ways should I choose so that automatic updates still run for and apply to Nginx and its optional modules? Or should I create a cron job with a command/script specific for Nginx instead of using unattended-upgrades utility? Can I choose between volume updates and security-only updates to be automatically applied to the standard and optional modules? And finally, is there a possibility to automatically update Nginx's modules on the fly (without any connections having been dropped), like the documentation suggests it's possible with sudo kill -USR2 $( cat /run/nginx.pid ) P.S. Actually I'm not certain if unattended-upgrades utility would automatically update the standard modules in the first place, not enough time has passed since Nginx was installed to say for sure.

• Install Ubuntu or Kubuntu?

  - by squallbayu

  I want to upgrade my Ubuntu Lucid to Kubuntu Maverick (with a fresh install of course). I want to try KDE, but I have heard there are slight issues with the native QT applications compared to the GTK application equivalents - such as nvidia-settings, Gimp, Ubuntu Software Centre, and especially th eSynaptic package manager (which in detail showed the administration package / KPackageKit is not powerful yet than synaptic) I believe we can have run GTK+ applications in KDE, but GTK+ applications do not blend with the KDE desktop. Also Java does not provide a GUI for KDE/QT. Should I install Kubuntu (KDE / QT) or stay with ubuntu (GNOME / GTK +)?

• Internal and external API architecture

  - by Tacomanator

  The company I work for maintains a successful SaaS product that grew "organically" over the years. We are planning to expand the line with a suite of new products that will share data with the existing product. To support this, we are looking to consolidate business logic into a single place: a web service layer. The WS layer will be used by: The web applications A tool to import data A tool to integrate with other client software (not an API per se) We also want to create an API that can be used by our customers that are capable of using it to create their own integrations. We are struggling with the following question: Should the internal API (aka the WS layer) and the external API be one in the same, with security and permission settings to control what can be done by who, or should they be two separate applications where the external API just calls the internal API like any other application? So far in our debate it seems that separating them may be more secure, but will add overhead. What have others done in a similar situation?

• Setting Up and Managing Local IPS Repositories

  - by user12244672

  My colleague, Albert White, has published a useful article detailing how to set up local IPS repositories for use within an enterprise: How to Create Multiple Internal Repositories for Oracle Solaris 11 This is useful as most servers will not be directly connected to the Internet and most customers will want to control which Oracle Solaris SRUs (Support Repository Updates) are "qualified" for deployment within their organization.  Setting up and managing Internal IPS (Image Packaging System) Repositories is the way to do this. The concept can naturally be extended and adapted.  For example, Albert talks about a "Development" Repo containing the latest Oracle Solaris 11 deliverables.  When qualifying a software level for deployment across the enterprise, a copy of a specific level could be taken, e.g. "GoldenImage2012Q3" or "SRU8.5", and once it passes testing, be used to deploy across the enterprise. Best Wishes, Gerry.

• Strategies for Indexing Custom Fields in RavenDB

  - by Adrian Thompson Phillips

  In the relational database world, if I was developing a CRM system and wanted to have the user add their own custom fields that are searchable, I could have tables that store the name of the new column, the data type and the value, etc. (which would be less inefficient to index) or I could use the less elegant (but more searchable) solution that software like Dynamics and SharePoint use, whereas I create a load of columns on my aggregate root called CustomInt1, CustomInt2, etc. (which looks dirty and has a limit of how many custom fields a user can have, but has indexing advantages). But my questions is this, in NoSQL databases, what would be the best way of achieving the same thing? My priority would be for searchability. So what would be the best way to store this data? If I used a predefined set of properties (i.e. CustomData1, CustomData2, etc.), because these are all stored as JSON (i.e. strings) in the database, does this make it simpler because I don't have to worry about data types?

• How to build a team of people not working together?

  - by Bernd

  I am in charge of a group of about 30 software development experts and architects. While these people are co-located in the companies organization chart, they do not really feel as a team. This is due to their work enviroment: 1) The people are spread over eight locations, with a max. distance of about 1000km (this is Europe). 2) The people don't work as team but instead get called as single people (and sometimes small groups into projects for as long as the projects run. 3) Travelling is somewhat limited as this requires business reasons. Lot is done via phone. Do you have ideas or suggestions on how I could make these people feeling part of a joint organization where they support others and get supported by others. So that they get to know their peers, build a network, informally exchange information? So that they generally get the feeling of having common ground and derive motivation and job satisfaction?

• Is it possible to use Google Analytics to track file downloads?

  - by Eric Falsken

  It's always bothered me that Google Analytics (and similar embedded web traffic monitoring services) can only see a reflection of the traffic going to my server and can only see page visits since it depends on the browser executing a Javascript snippet. If I want to track real downloads of a software package (ZIP file), there's no way Google Analytics can possibly tell me that because its javascript can't be attached to a ZIP file. Is there a way I can upload my log files to Google so that the pointy-haired boss can see downloads of our ZIP/PDF/BIN files and not just visits to the download page?

• Studies on code documentation productivity gains/losses

  - by J T

  Hi everyone, After much searching, I have failed to answer a basic question pertaining to an assumed known in the software development world: WHAT IS KNOWN: Enforcing a strict policy on adequate code documentation (be it Doxygen tags, Javadoc, or simply an abundance of comments) adds over-head to the time required to develop code. BUT: Having thorough documentation (or even an API) brings with it productivity gains (one assumes) in new and seasoned developers when they are adding features, or fixing bugs down the road. THE QUESTION: Is the added development time required to guarantee such documentation offset by the gains in productivity down-the-road (in a strictly economical sense)? I am looking for case studies, or answers that can bring with them objective evidence supporting the conclusions that are drawn. Thanks in advance!

• How do I copy an existing hard disc to a new one so I can boot off the new disc?

  - by Brian Hooper

  I currently have a failing hard drive which is the only hard drive in the machine. I have just bought a new hard drive to replace it, and my plan is to copy the contents of the old drive onto the new one, and then replace the old drive in the machine with the new one. I presumably can't just copy the whole directory structure (or can I)? What do I need to do to manage this, assuming it is possible? Is there a utility to do this for me? (The old drive is hopefully good for a few more hours.) (I hope by this means to keep all the software and configuration files as they are, to avoid having to re-install everything. Can that be done?)

• Preparing for interview questions involving scale

  - by Chaitanya

  I have over 6 years of software development experience. I have worked on multiple platforms, including mobile. However, I have not had a chance of working on scale-related issues. As a consequence, whenever someone asks a question involving a million inputs in an interview, I find myself out of depth. How do I prepare for such questions? Any books/resources to refer to? There are books for Java and Data Structures and Concurrency, but I don't know about any definitive ones to learn about scaling.

• Should I incorporate exit cost into choosing a solution

  - by Mr Happy

  I'm currently choosing between two viable software designs/solutions. Solution 1 is easy to implement, but will lock some data in a propriaty format, and will be hard to change later. Solution 2 is hard to implement, but will be a lot easier to change later on. Should I go YAGNI on this or should I incorporate the exit cost in the decision making? Or asked differently, is the exit cost part of the TCO? I'm thinking of going back to the customer with this to ask wether or not he thinks the exit costs are relevant, but I'd like to know what the community thinks first. P.S. Is exit cost the correct term?
