• How do software updates work on Ubuntu?

  - by Jonas

  I would like to know how software updates work for my Ubuntu Server 10.10. I have been recommended to use apt-get install for installing new software and apt-get update for updating software for a Ubuntu Server in production use. Because these packages are tested for Ubuntu in contrast to download source code and compile the software on the box. But on my Ubuntu Server 10.10, I don't get the latest stable version of PostgreSQL (9) or the latest stable version of Nginx (8) using apt-get install. So how is this working, will these software be updated when I later run apt-get update or do I have to later run apt-get install again, or do I have to wait for the next release of Ubuntu to get them? And are patches and security updates managed in the same way? Or can they be updated automatically? If there is such a setting, how do I check what my system is using?

• How to protect own software from copying [closed]

  - by Zzz

  Possible Duplicate: How do you prevent the piracy of your software? Is possible to protect some file from copying if you are administrator of machine? I heard some story about some behavior: one software developer sells his software in some way. He is installing it on every client's computer and this software does not work on other computers or cannot be copied physically. How to implement the first and second protection. Is it effectively protection if software costs about $100 for all copies across client's company?

• Photo Gallery Software - reads from a local directory - watches folder- user and group permissions

  - by Darkflare

  Use Case: Photos are organised in a folder structure by date (by software lightroom/picasa) Want to run a local webserver to host a web gallery from (already know how to run lamp etc) I want to be able to attach metadata to the photos (probably through a database not residing in the photos folder) such that they can be tagged/categoried/albumed without affecting the original photos I want to be able to assign permissions to different albums to set users I want the software to watch the photo source folder for changes so that new photos are indexed ready for applying metadata and albums. I'd like the software to handle the rendering of numerous file types (photo formats) as well as video formatts I am language agnostic so php/python heck even c#, just want software that forfills the requirements. The main reason I am asking this question here as I am unsure what this software would even be called so google searching is quite difficult! Thanks for reading.

• Torrents: Can I protect my software by sending wrong bytes?

  - by martijn-courteaux

  Hi, It's a topic that everyone interests. How can I protect my software against stealing, hacking, reverse engineering? I was thinking: Do my best to protect the program for reverse engineering. Then people will crack it and seed it with torrents. Then I download my own cracked software with a torrent with my own torrent-software. My own torrent-software has then to seed incorrect data (bytes). Of course it has to seed critical bytes. So people who want to steal my software download my wrong bytes. Just that bytes that are important to startup, saving and loading data, etc... So if the stealer download from me (and seed it later) can't do anything with it, because it is broken. Is this idea relevant? Maybe, good torrent-clients check hashes from more peers to check if the packages (containing my broken bytes) I want to seed are correct or not? Thanks

• Where to find and download a new suitable software? [closed]

  - by user63411

  Possible Duplicate: How do you find a new software to download? I see that the most time I spend on the computer I lose to just searching for suitable software. How you do it? What is your way to find software? Do you first go to a forum or google? Which torrent site? which P2P program, website or server? For example: "I need a software that have functions as a remote desktop and also lets you copy and paste (drag and drop - file manager). And after few hours searching on Google I downloaded LOGMEIN Pro2, but than I see that is just trial. So if I need to find alternative I will spend another whole day. Where to go? I am not an amateur but I need a better system. I need better introduction on how to find what is the suitable software.

• How to list manually installed software packages in Ubuntu?

  - by Ivan Petrushev

  Hello, I'm using apt-get install to install various software on my PC. I have a handful of PCs that needs the same software packages installed all over them. How can I get list of software installed via apt-get install and the sequence in what the packages are installed. Okay, the sequence is not so important since the package manager resolves dependencies... I want to create a script that once run installs all needed software on the other PCs. All of these PCs are Ubuntu default installations. It is obvious that the packages list must not include all the packages that are installed trough a default installation :) Also that list should not contain software installed via synaptic or dpkg if possible.

• What ever happened to the Defense Software Reuse System (DSRS)?

  - by emddudley

  I've been reading some papers from the early 90s about a US Department of Defense software reuse initiative called the Defense Software Reuse System (DSRS). The most recent mention of it I could find was in a paper from 2000 - A Survey of Software Reuse Repositories Defense Software Repository System (DSRS) The DSRS is an automated repository for storing and retrieving Reusable Software Assets (RSAs) [14]. The DSRS software now manages inventories of reusable assets at seven software reuse support centers (SRSCs). The DSRS serves as a central collection point for quality RSAs, and facilitates software reuse by offering developers the opportunity to match their requirements with existing software products. DSRS accounts are available for Government employees and contractor personnel currently supporting Government projects... ...The DoD software community is trying to change its software engineering model from its current software cycle to a process-driven, domain-specific, architecture-based, repository-assisted way of constructing software [15]. In this changing environment, the DSRS has the highest potential to become the DoD standard reuse repository because it is the only existing deployed, operational repository with multiple interoperable locations across DoD. Seven DSRS locations support nearly 1,000 users and list nearly 9,000 reusable assets. The DISA DSRS alone lists 3,880 reusable assets and has 400 user accounts... The far-term strategy of the DSRS is to support a virtual repository. These interconnected repositories will provide the ability to locate and share reusable components across domains and among the services. An effective and evolving DSRS is a central requirement to the success of the DoD software reuse initiative. Evolving DoD repository requirements demand that DISA continue to have an operational DSRS site to support testing in an actual repository operation and to support DoD users. The classification process for the DSRS is a basic technology for providing customer support [16]. This process is the first step in making reusable assets available for implementing the functional and technical migration strategies. ... [14] DSRS - Defense Technology for Adaptable, Reliable Systems URL: http://ssed1.ims.disa.mil/srp/dsrspage.html [15] STARS - Software Technology for Adaptable, Reliable Systems URL: http://www.stars.ballston.paramax.com/index.html [16] D. E. Perry and S. S. Popovitch, “Inquire: Predicate-based use and reuse,'' in Proceedings of the 8th Knowledge-Based Software Engineering Conference, pp. 144-151, September 1993. ... Is DSRS dead, and were there any post-mortem reports on it? Are there other more-recent US government initiatives or reports on software reuse?

• Maven doesn't compile target/hibernate3/generated-sources

  - by mmm

  Can someone tell me how to configure maven for it also to compile sources from the target/hibernate3/generated-sources directory? I have already read this and other posts but they don't seem to solve my problem (which indeed seems trivial). I have used the bottom-up approach hibernate configuration for cfg.xml, hbm.xml and POJO generation (i.e. auto-generated the complete hibernate configuration out of an existing database schema). I'm also only using standard maven and hibernate3-plugin directory layouts. Yet, when executing mvn compile in the command-line while my sources are in the src/main/java and the generated sources in /target/hibernate3/generated-sources only the ones from src/main/java get compiled and copied into target/classes. I wouldn't like to generate sources into src/main/java as I'd like mvn clean to clean them. I'd like to solve the problem using command-line, plugins and pom.xml only. Is there a way to configure maven-compiler-plugin to do so? Or is there another way? Regards and thanks for any help.

• Embeddable forum software

  - by Rented

  I am in the planning stages of a specific subject matter community web site, and one feature I feel is required is that of member discussions. However, not in a typical forum style. For example, I don't want the members to have to navigate away from their own "user space" in order to discuss a topic. I think it is best described with an analogous example. Lets say the site is for literature buffs, and each member has a set of pages for keeping notes, progress, questions, etc. on books they are studying/reading. So Joe will have one page for Great Expectations, another for Hamlet, a third for I, Robot, and so forth. Likewise, Jane will have a page for Don Quixote, Lord of the Flies, and also I, Robot. Now, wouldn't it be nice if Joe and Jane could discuss I, Robot from within their own respective pages? Now, at first thought, roll your own seems like the way to go. However, once we start getting into issues such as spam blocking, banning, ratings, pruning, archiving, flooding and so on, well "roll your own" doesn't sound too appealing anymore. Also, I have next to zero experience with forum software. So I'm looking for forum software that has an extensive API or is generally very integration-friendly. I would like to be able to create user groups, topics, permissions, etc. programmatically,as well as the obvious user authentication (most seem open in that respect). The site will most probably be built with Java. Tangler seems like a descent option, but it seems less mature than what I'd prefer.

• software distribution and patch management

  - by daemonkid

  How do software houses like Microsoft or anti-virus companies patch/update their software? Anti virus companies dont send the complete executable; only new virus signatures I suppose. Similarly, Ive noticed microsoft sends certain files to the '$NtUninstallKB......$' folder that it creates when it the windows update program runs. I suppose there is an installer in each such folder there that replaces only those dlls that need to be updated or fixed. Questions Is there a universal method for doing this or does each house employ their own methods? I dont want to re-send the entire application to each individual client. Suppose if only certain dlls need to be changed or maybe some more added, how should I go about planning my final compiled application. Do I need to look at separating my application into multiple assemblies? If yes, then is there some compilation method that is allows to pack specific classes into a particular dll? What I have put down here are my thoughts on the subject and I could be wrong. Could anyone throw some light on this please? I am looking at implementing such a deployment and patch management technique for the .net platform. Thanks for your time.

• The Implications of Modern Day Software Development Abstractions

  - by Andreas Grech

  I am currently doing a dissertation about the implications or dangers that today's software development practices or teachings may have on the long term effects of programming. Just to make it clear: I am not attacking the use abstractions in programming. Every programmer knows that abstractions are the bases for modularity. What I want to investigate with this dissertation are the positive and negative effects abstractions can have in software development. As regards the positive, I am sure that I can find many sources that can confirm this. But what about the negative effects of abstractions? Do you have any stories to share that talk about when certain abstractions failed on you? The main concern is that many programmers today are programming against abstractions without having the faintest idea of what the abstraction is doing under-the-covers. This may very well lead to bugs and bad design. So, in you're opinion, how important is it that programmers actually know what is going below the abstractions? Taking a simple example from Joel's Back to Basics, C's strcat: void strcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); } The above function hosts the issue that if you are doing string concatenation, the function is always starting from the beginning of the dest pointer to find the null terminator character, whereas if you write the function as follows, you will return a pointer to where the concatenated string is, which in turn allows you to pass this new pointer to the concatenation function as the *dest parameter: char* mystrcat( char* dest, char* src ) { while (*dest) dest++; while (*dest++ = *src++); return --dest; } Now this is obviously a very simple as regards abstractions, but it is the same concept I shall be investigating. Finally, what do you think about the issue that schools are preferring to teach Java instead of C and Lisp ? Can you please give your opinions and your says as regards this subject? Thank you for your time and I appreciate every comment.

• No alternative drivers appearing on Software Sources and manual install leads to no unity

• Sources (other than tutorials) on Game Mechanics

  - by Holland

  But, I'm not quite sure where I should start from here. I know I have to go and grab an engine to use with some prebuilt libraries, and then from there learn how to actually code a game, etc. All I have right now is some "program Tetris" tutorial for C++ open right now, but I'm not even sure if that will really help me with what I want to accomplish. I'm curious if there are is any good C++ documentation related to game development which provides information on building a game in more of a component model (by this I'm referring to the documentation, not the actual object-oriented design of the game itself), rather than an entire tutorial designed to do something specific. This could include information based on various design methodologies, or how to link hardware with OpenGL interfaces, or just simply even learning how to render 2D images on a canvas. I suppose this place is definitely a good source :P, but what I'm looking for is quite a bit of information - and I think posting a new question every ten minutes would just flood the site...

• Software Architecture and Design vs Psychology of HCI class

  - by Joey Green

  I have two classes to choose from and I'm wanting to get an opinion from the more experienced game devs which might be better for someone who wants to be an indie game dev. The first is a Software Architecture and Design course and the second is a course titled Psychology of HCI. I've previously have taken a Software Design course that was focused only on design patterns. I've also taken an Introduction to HCI course. Software Architecture and Design Description Topics include software architectures, methodologies, model representations, component-based design ,patterns,frameworks, CASE-based desgins, and case studies. Psychology of HCI Description Exploration of psychological factors that interact with computer interface usablilty. Interface design techniques and usability evaluation methods are emphasized. I know I would find both interesting, but my concern is really which one might be easier to pick up on my own. I know HCI is relevant to game dev, but am un-sure if the topics in the Software Architecture class would be more for big software projects that go beyond the scope of games. Also, I'm not able to take both because the overlap.

• Integrating different branches from external sources into a single Mercurial repository

  - by dukeofgaming

  I'm currently working in a company using Perforce and am making way for distributed version control with Mercurial. I've had success importing Perforce history using the perfarce (quite a suitable name, I laugh every time I see/say it) however, this only works with a single branch at a time. Here's how my P4 integration setup works: In perforce, create a "client", which is kind of a description of what you will be constantly updating/checking-out. This can only address one branch at a time (trunk or other). Once you do this, run hg clone p4://<server>/<client_name> Go to .hg/hgrc and put the perforce path line: perforce = p4://<server>/<client_name> Work normally with the code under mercurial, do hg pull perforce to sync up, hg push to export a changelist What I'd like to be able to do is have a perforce path per branch and have everything work in the same repository. Now, pushing is not a problem, however, if I pull the history from another branch it would end up at the default branch. I'd like to be able to do something like hg pull perforce-R5 and have it land in mercurial's R5 branch. Even if I have no merging history, it would be sweet enough to be able to preserve it. There are also other plugins for CVCSs that let you integrate mercurial, but AFAIK the subversion one has the same problem. I don't think there is a straight-through way of doing this, but as long as I could automate the process with some hooks and scripts in a single Mercurial machine, that would be good enough.

• Designing a large database with multiple sources

  - by CatchingMonkey

  I have been tasked with redesigning, or at worst optimising the structure of a database for a data warehouse. Currently, the database has 4 other source databases (which is due to expand to X number of others), all of which have their own data structures, naming conventions etc. At the moment an overnight SSIS package pulls the data from the various source and then for each source coverts the data into a standardised, usable format. These tables are then appended to each other creating a 60m row, 40 column beast!. This table is then used in a variety of ways from an OLAP cube to a web front end. The structure has been in place for a very long time, and the work I have been able to prove the advantages of normalisation, and this is the way I would like to go. The problem for me is that the overnight process takes so long I don't then want to spend additional time normalising the last table into something usable. Can anyone offer any insight or ideas into the best way to restructure or optimise the database efficiently? Edit: All the databases are MS SQL Server 2008 R2 Thanks in advance CM

• Can unit tests verify software requirements?

  - by Peter Smith

  I have often heard unit tests help programmers build confidence in their software. But is it enough for verifying that software requirements are met? I am losing confidence that software is working just because the unit tests pass. We have experienced some failures in production deployment due to an untested\unverified execution path. These failures are sometimes quite large, impact business operations and often requires an immediate fix. The failure is very rarely traced back to a failing unit test. We have large unit test bodies that have reasonable line coverage but almost all of these focus on individual classes and not on their interactions. Manual testing seems to be ineffective because the software being worked on is typically large with many execution paths and many integration points with other software. It is very painful to manually test all of the functionality and it never seems to flush out all the bugs. Are we doing unit testing wrong when it seems we still are failing to verify the software correctly before deployment? Or do most shops have another layer of automated testing in addition to unit tests?

• Class design, One class in two sources

  - by Pavla

  Is it possible define methods from the same class in different "CPP" files? I have header file "myClass.h" with: class myClass { public: // methods for counting ... // methods for other ... }; I would like to define "methods for counting" in one CPP and "methods for other" in other CPP. For clarity. Both groups of methods sometime use the same attributes. Is it possible? Thanks :).

• Flaws in my PHP development setup - sharing sources causing lags

  - by Wiktor

  I have following development setup for my PHP projects: Working station running on Windows 7 with PhpStorm IDE. GIT for version controlling. CentOS on virtual machine (VirtualBox) with Apache and MySQL (copy of production server). So far, I've been sharing project's source folders between host and guest systems and it was working quite well only really slow. The reason behind this is that Apache was reading files from remote folder (mounted locally). After doing some research, I found out that this set up can be improved by using disk mapping (Samba) instead of folder sharing. So I did that change. I configured my PhpStorm to automatically deploy files to mapped drive. Everything works like a charm now, except for one problem - when I change branches I need to synchronize project's local folder with the one on mapped drive and that takes time, a lot of time (like branching in SVN). Is there another way to handle this than just working on files directly on mapped drive?

• Best sources to find your go-to programmer

  - by user66851

  After exhausting many resources, time, interviews etc, I cannot seem to find the correct programming talent for our company. Any other resources you suggest besides Dice, Linkedin, Craigslist, University Job Boards, Poaching techniques....its been months now! Specifically, we designed proprietary data-manipulation and data-gathering technology, and are looking for skilled programmers requiring skills of PHP5/MySQL, Javascript/HTML/CSS , cross-browser compatibility/optimization, web interface development, familiarity with source control (SVN or GIT), any L/AMP stack, and/or related application protocols, GCC-supported languages, Zend Framework and/or jQuery.

• Plug-in based software design

  - by gekod

  I'm a software developer who is willing to improve his software design skills. I think software should not only work but have a solid and elegant design too to be reusable and extensive to later purposes. Now I'm in search of some help figuring out good practices for specific problems. Actually, I'm trying to find out how to design a piece of software that would be extensible via plug-ins. The questions I have are the following: Should plug-ins be able to access each others functionality? This would bring dependencies I guess. What should the main application offer to the plug-ins if I want to let's say develop a multimedia software which would play videos and music but which could later on get functionality added over plug-ins that would let's say be able to read video status (time, bps, ...) and display it. Would this mean that the player itself would have to be part of the main program and offer services to plug-ins to get such information or would there be a way to develop the player as a plug-in also but offer in some way the possibility to other plug-ins to interact with it? As you see, my questions are mainly for learning purposes as I strive to improve my software development skills. I hope to find help here and apologize if something is wrong with my question.
