• Is there an RSS feed of Ubuntu Release torrent files

  - by Valorin

  A lot of torrent search engines have the ability to provide an RSS feed of matches, allowing you to set up torrent programs to download items which are published on the feed. This is useful for watching releases of things. The problem with doing this through a random search engine for Ubuntu is that you usually get too many torrents as it picks up different custom versions, and other software with the name in the title/description. See: http://www.mininova.org/rss/ubuntu So I was wondering if there was an RSS feed somewhere that only loads up the official torrent files for releases?

• Reverse horizontal and vertical for a HTML table

  - by porton

  There is a two-dimensional array describing a HTML table. Each element of the array consists of: the cell content rowspan colspan Every row of this two dimensional array corresponds to <td> cells of a <tr> of the table which my software should generate. I need to "reverse" the array (interchange vertical and horizontal direction). Insofar I considered algorithm based on this idea: make a rectangular matrix of the size of the table and store in every element of this matrix the corresponding index of the element of the above mentioned array. (Note that two elements of the matrix may be identical due rowspan/colspan.) Then I could use this matrix to calculate rowspan/colspan for the inverted table. But this idea seems bad for me. Any other algorithms? Note that I program in PHP.

• Build a custom Ubuntu based distribution

  - by user51447

  I am working on making a custom Ubuntu 11.10 based distro.(64 bit) I am adding non open source packages, replacing packages, changed user interface from Unity to GNOME, and more changes. My system is ready, and I want to create a redistributable image for my distro. When you go to system settings - system info, you see a logo with the Ubuntu name and logo, but I want to change it to the name and logo of my distro. Also, in the boot menu, I want to change the boot entry names, and the GRUB background. And I want to change the name Ubuntu from every possible location. Also, I will be sharing it with people, so I want to make my own software repositories, like linux mint has, or any other distro has, I will purchase server space for that. Also, the I want to customize the wubi installer like linux mint did and if some uses the customized tool to install my distro from Windows, they should see the name of my distro in add or remove programs page. Any help will be appreciated!

• When to roll your own game engine?

  - by Joey Green

  I've been a software developer for 5 years now and wanting to get into iOS game development. I've played around with the iOS SDK for about 2 years now, attending cocoaheads meetings and feel I have a good grasp on objective-c/cocoa and even c/c++. I have a game idea and know that I will use Box2D but I'm wondering if I should use cocos2D or not. The main reasons are: I may want to do things graphics wise that aren't available in cocos2d. If I roll my own game engine I'll have more control. Of course the main reason for using a already existing game engine is the time it saves and it makes the hard stuff easier, but for someone who has the technical chops to roll his own does it make sense?

• What resources will help me understand the data model for QC 10.0 in order to write my SQL queries?

  - by srihari

  I am a fresher in Quality Center 10.0 HP software testing tool. As per my understanding in order to generate reports from QC and to troubleshoot the scenarios, we need to write SQL queries in the QC back end database. In my case it is SQL db. I downloaded the database reference help file but I could not understand from where I can start. It just gave the table name and its information. For a starter like me are there any online tutorials or helpful websites,hands on exercises,scenario's where I can better understand how to write queries for the QC data model? I am very confident about the SQL coding itself, what I want to know is how to query on the QC database tables based on the scenarios that occur in QC tool. Please suggest. Thanks, Srihari

• Better Programming By Programming Better?

  - by ahmed

  I am not convinced by the idea that developers are either born with it or they are not. Where’s the empirical evidence to support these types of claims? Can a programmer move from say the 50th to 90th percentile? However, most developers are not in the 99th or even 90th percentile (by definition), and thus still have room for improvement in programming ability, along with the important skills.The belief in innate talent is “lacking in hard evidence to substantiate it” as well.So how do I reconcile these seemingly contradictory statements? I think the lesson for software developers who wish to keep on top of their game and become experts is to keep exercising the mind via effortful studying. I read a lot technical books, but many of them aren’t making me better as a developer.

  - by Howard Graham

  I'm trying to install Epson V100 scanner in 12.04.

• Performance tracking/monitoring in games

  - by vitaliy kotik

  Let's say I have an online game with a downloadable client / browser plugin. I want to track performance of my software and automatically send summary to the server. Let it be fps, latency, load time, physics step calc. time, whatever... I also want tools to perform data analysis: per session stats, per hardware stats, avgs, totals, diagrams, etc. So that I could see what are the real world hotspots / bottlenecks. Is there any common out-of-the-box / SaS solution?

• Laptops or Notebooks in a meeting? [closed]

  - by greengit

  Is taking the laptop to the meeting a good idea? Of course, the project leader needs to have one -- but the programmers -- especially those who only need to get straight instructions on what to do next on the project -- do they need to take laptops? I feel it takes longer to save notes in a software -- and it's lot easier to just jot down "things to do" in a simple note book. That way you can keep up with the discussion and not lose track of what someone else is saying by spending too much time entering text in the machine.

• How/where to run the algorithm on large dataset?

  - by niko

  I would like to run the PageRank algorithm on graph with 4 000 000 nodes and around 45 000 000 edges. Currently I use neo4j graph databse and classic relational database (postgres) and for software projects I mostly use C# and Java. Does anyone know what would be the best way to perform a PageRank computation on such graph? Is there any way to modify the PageRank algorithm in order to run it at home computer or server (48GB RAM) or is there any useful cloud service to push the data along the algorithm and retrieve the results? At this stage the project is at the research stage so in case of using cloud service if possible, would like to use such provider that doesn't require much administration and service setup, but instead focus just on running the algorith once and get the results without much overhead administration work.

• Approach on working with many programmers on one module/feature

  - by Panoy

  How can 2 or more developers code a certain feature/module of a software? Let's assume that the module is big and feature rich. How would they prevent each other from overlapping their code? Say, we have the same method but is implemented in a different way. Do you think it might be better to have one focused at a specific feature only? Is a version control system like Git would help solve the problem? Is it correct that it allows developers to have these "branches" and then merge it later on? What's your take on this?

• Script to only execute during first install of a package

  - by Jeroen

  I recently started packaging up some of my software and publishing it on Launchpad. The installation and removal works fine, but upgrading the package form one version to the next version is problematic. The problem is that there are some scripts that only need to run during the first installation of the package. These scripts populate the DB, create a user, etc. They are currently called in the package.postinst configure) section. However this results in them being called during an upgrade as well as shown in the diagram. Is there a way to include a maintainer script in a .deb package that only executes during the first installation of the package and not during an upgrade? Or what would be an elegant way to include some initial setup scripts in a .deb package?

• Problems detecting android tablet IView 788TPC with mtp-tools

  - by Elder Geek

  I installed mtp-tools on 14.04 "Trusty" through Software Center. No problems with install. Issuing `mtp-detect' results in 'Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6 Listing raw device(s) No raw devices found.' I did some research and found that mtpfs might be required. so installed that with :~$ sudo apt-get install mtpfs I still get the following result :~$ mtp-detect Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6 Listing raw device(s) No raw devices found. My research indicates that the mtp-tools package is still under development. source: http://libmtp.sourceforge.net/ and the documentation is not comprehensive. source man mtp-tools as well as mtp-detect -h I tried adding the PPA from Are there any plans to improve mtp support on future Ubuntu releases? but it seems this is already worked into trusty 14.04 and won't resolve the problem. Can anyone provide a recommended course of action to resolve this problem?

• C++ Library API Design

  - by johannes

  I'm looking for a good resource for learning about good API design for C++ libraries, looking at shared objects/dlls etc. There are many resources on writing nice APIs, nice classes, templates and so on at source level, but barely anything about putting things together in shared libs and executables. Books like Large-Scale C++ Software Design by John Lakos are interesting but massively outdated. What I'm looking for is advice i.e. on handling templates. With templates in my API I often end up with library code in my executable (or other library) so if I fix a bug in there I can't simply roll out the new library but have to recompile and redistribute all clients of that code. (and yes, I know some solutions like trying to instantiate at least the most common versions inside the library etc.) I'm also looking for other caveats and things to mind for keeping binary compatibility while working on C++ libraries. Is there a good website or book on such things?

• How to document/verify consistent layering?

  - by Morten

  I have recently moved to the dark side: I am now a CUSTOMER of software development -- mainly websites. With this new role comes new concerns. As a programmer i know how solid an application becomes when it is properly layered, and I want to use this knowledge in my new job. I don't want business logic in my presentation layer, and certainly not presentation stuff in my data layer. Thus, I want to be able to demand from my supllier that they document the level of layering, and how neat and consistent the layering is. The big question is: How is the level of layering documented to me as a customer, and is that a reasonable demmand for me to have, so I don't have to look in the code (I'm not supposed to do that anymore)?

• Renovación de equipos antiguos y los TCO

  - by Eloy M. Rodríguez

  Acabo de ver un vídeo de Oracle sobre las ventajas económicas y de eficiencia que aportan los programas en marcha de renovación de base instalada. Con los recientes anuncios de los SPARC T4 y SuperCluster las ventajas se refuerzan. Y en España sigue habiendo una importante base instalada de sistemas Sun en la sanidad. En el vídeo me ha llamado la atención que se destaque algo que casi nunca se hace: el reciclado de los sistemas antiguos. Son tres minutos y medio y es muy fácil de seguir por sus grafismos y por el inglés muy entendible con que se expresa el presentador. Al final, estamos hablando de TCO, el cada vez más famoso Coste Total de Propiedad, tema que cada vez debería de tomar peso a la hora de las decisiones sobre el coste de adquisición. Prueba de ello es que el gobierno de Gran Bretaña ha publicado una primera guía de criterios de consideración a la hora del cálculo del TCO de productos de software. Animo a echarle un vistazo, porque pone en papel organizadamente lo que todos conocemos, pero que siempre es bueno tenerlo sistematizado.

• Video Training Courses for Linux/Ubuntu?

  - by Anil

  I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.
