• Advantages And Disadvantages Of Resource Serialization

  - by CPP_Person

  A good example is let's say I'm making a pong game. I have a PNG image for the ball and another PNG image for the paddles. Now which would be better, loading the PNG images with a PNG loader, or loading them in a separate program, serializing it, and de-serializing it in the game itself for use? The reason why this may be good to know is because it seems like game companies (or anyone in the long run) build all of their resources into some sort of file. For example, in the game Fallout: New Vegas the DLCs are loaded as a .ESM file, which includes everything it needs, all the game does is find it, serialize it, and it has the resources. Games like Penumbra: Black Plague take a different approch and add a folder which contains all the textures, sounds, scrips, ect that it needs, but not serialized (it does this with the game itself, and the DLC). Which is the better approch and why?

• Should devs, testers and business users have one unified test script?

  - by Carlos Jaime C. De Leon

  In development, I would normally have my own test scripts that would document the data, scenarios and execution steps that I plan to test; this is my dev test plan. When the functionality has been deployed to Test, testers test it using their own test script that they wrote. In UAT, the business user then tests using their own test plan. In retrospect, it looks like this provides a better coverage, with dev tests having a mix of black and white box testing, while testers and business users focus on black box testing. But on the other hand, this brings up distinct test cases that only are executed per stage (ie. some cases which testers thought of are only executed on Test stage) and it would like the dev missed it, which makes it a finding/bug. Is it worth consolidating the test scripts from the start? Thus using one unified test script, or is it abit difficult to do this upfront?

• How do I install Nautilus-Elementary?

  - by Srinivas G

  I've added the am-monkeyd PPA and upgraded my system. Yet, there's no sign of elementary in my fresh Maverick RC install. Have I done anything wrong? The PPA upgrades the default nautilus package and there is no separate "nautilus-elementary" package as of now. Now, there are three versions listed in the package properties: 1:2.32.0-0ubuntu1-ppa1 (maverick); 1:2.32.0-0ubuntu5~ppa5 (maverick); 1:2.32.0-0ubuntu1 (maverick); Anything you can make out from this?

• Did You Know? What PreCon would I take if I were attending TechEd?

  - by Kalen Delaney

  TechEd starts in 3 weeks, and I'm not going to make it this year. I had very much wanted to visit New Orleans post-Katrina and see the recovery for myself. I attended a couple of TechEd's there many years ago, but my primary reason for visiting that fabulous city was because my daughter went to school there. She graduated from Tulane University in 1999, but it just so happened that every time TechEd was there, it was after school was over for the year, so I never got to combine my conference trip...(read more)

• Developing my own package manager: how do I resolve dependencies?

  - by shantanu

  According to debian control file ant package's dependency list is: Depends: default-jre-headless | java2-runtime-headless | java5-runtime-headless | java6-runtime-headless, libxerces2-java That means it depends on default-jre-headless or java2-runtime-headless or java5-runtime-headless or java6-runtime-headless. But how could i determine that which package need to select as dependency? Note: I am trying to develop a package manager. I can not use provided package because they read sources.list file from a specific directory.

• Fan always spinning on Maverick

  - by jb

  I use Dell Studio 1555, after update to maverick my fan started spinning full speed allways. I use xserver-xorg-video-ati/radeon drivers because fglrx messes with my desktop resolution when connecting external screen. Processor is mostly idle. U use some desktop effects. On the same configuration on Lucid my fan worked slower. It eats lots of battery time :( Bug filed: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/675156 Any insights how to solve/debug it or work around it?

• Unable to install any packages due to unrecoverable fatal error /var/lib/dpkg/diversions

  - by gforces

  I am currently unable to install any packages. I receive the following error: dpkg: unrecoverable fatal error, aborting: too-long line or missing newline in `/var/lib/dpkg/diversions I have tried various approaches: sudo dpkg --configure -a sudo apt-get clean sudo dpkg-divert --list sudo apt-get check sudo apt-get install -f etc. but all to no avail. Either the output was apparently normal or the error above was thrown. I'm stumped as to how to proceed and would appreciate any assistance. If any further info is required just ask. Thanks for the reply. I followed the suggestions and am now getting a different error: (Reading database ... 50%dpkg: unrecoverable fatal error, aborting: files list file for package 'libksane0' is missing final newline E: Sub-process /usr/bin/dpkg returned an error code (2) Here is the link for the current diversions: http://paste.ubuntu.com/823500/ and the old broken one: http://paste.ubuntu.com/823502/ I tried to reinstall libksane0 but the same error occurred.

• Executive Edge: It's the end of work as we know it

  - by Naresh Persaud

  If you are at Oracle Open World, it has been an exciting couple of days from Larry's keynote to the events at the Executive Edge. The CSO Summit was included as a program within the Executive Edge this year. The day started with a great presentation from Joel Brenner, author of "America The Vulnerable", as he discussed the impact of state sponsored espionage on businesses. The opportunity for every business is to turn security into a business advantage. As we enter an in-hospitable security climate, every business has to adapt to the security climate change.  Amit Jasuja's presentation focused on how customers can secure the new digital experience. As every sector of the economy transforms to adapt to changing global economic pressures, every business has to adapt. For IT organizations, the biggest transformation will involve cloud, mobile and social. Organizations that can get security right in the "new work order" will have an advantage. It is truly the end of work as we know it.  The "new work order" means working anytime and anywhere. The office is anywhere we want it to be because work is not a place it is an activity. Below is a copy of Amit Jasuja's presentation. Csooow12 amit-jasuja-securing-new-experience6 from OracleIDM

• What is your favorite password storage tool?

  - by Marcel Levy

  Aside from personal passwords, I'm always juggling a number of project-specific passwords, including those for network, web and database authentication. Some authentication can be managed with ssh keys and the like, but everywhere I've worked I also faced the need for the management of passwords that need to be available to a number of different people. So what do you use, either for personal or team-based password management? Personally I'd like to hear about cross-platform tools, but I'm sure other people would be satisfied with Windows-only solutions. I know the stackoverflow podcast tackled this issue in #7 and #9, but I'm hoping we can come up with the definitive answer here. Update: Even though this question was asked before its sibling site existed, you should probably add your two cents to the more active question over at superuser, which is a more appropriate venue for this.

• How to determine if a package is a meta-package from the command line?

  - by cirosantilli

  How can I determine if a package is a meta-package from the command line, possibly via apt-get, aptitude or apt-cache? I have tried: apt-cache show texlive-full apt-cache showpkg texlive-full but the only way I can tell this package is meta is by reading the "en-description" field. Is there a more automatic way of doing this, that will give me a yes/no response, or at least have a field such as then "en-description" dedicated to this?

• always purge on remove in package

  - by Jeroen

  Is there a way I can set my package to always automatically include a --purge whenever a user does a regular apt-get remove mypackage ? The reason is that I have some config files in /etc that should really be removed when the binaries are removed, otherwise it can lead to weird behavior. However I still want to treat them as conf files, i.e. make sure apt does not just wipe them on every upgrade of the package. But they should be removed when the package is uninstalled. Currently I am manually deleting the /etc conf files in my postrm script. However I just found out that this has a unfortunate side effect: if the user uninstalls and then later re-installs the package, the conf files won't be reinstalled, because apt thinks that they are still there. So is there a way I can manually trigger a full 'purge' in my postrm, such that apt knows that the conf files are gone?

• What is a good site to use for scheduling 20+ developers and 10 projects? (resource planning) [closed]

  - by b-ryce

  I have around 20 developers and 10 or so active projects. Then I get asked if my team can take on more work, and who is going to free up when. Currently we are using a spreadsheet to keep track :( I've been digging around for a few hours and haven't found anything that meets my requirements, which are: Web based Schedule a developer's time over a period of days/weeks/months Be able to see at a glance which developer has extra capacity Quickly see when the group could take on another large project I don't mind paying for the software (It does NOT need to be free) Two projects which look close are http://www.ganttic.com/tour and http://resourceguruapp.com/ What else are people using? Anyone have the perfect solution

• 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?

• What is the best solution for document archiving?

  - by Anders Wallenquist

  I'm looking for a utility that helps me (and my colleagues) to archive documents in a systematic manner (Like Zeitgeist but permanent). The utility have to clean-out old document from desktops and store them on a server (as automatic as possible and consistent) maybe from just a few locations (Document directory) Documents shall be stored on cheap large media for many years to come - hard disk and file system maybe? Easy to maintain and manage for a small organization. Documents have to be easy to find and restore One systematic manner could be a directory-structure by year, month, user or user, year, month. Its a plus if documents could be linked to a project, if documents could be search-able and if document could also be mail, IM-discussions not only OpenOffice traditional documents. Any ideas?

• MBO in software development

  - by Euphoric

  I just found out our middle sized software development company is going to implement MBO. As a big fan of Agile, I see this as counter-intuitive, because I believe it is impossible to create a objective, that is measurable. Especialy where creativity, experience, knowledge and profesionalism are important traits and expanding those are objectives and goals of many. So my question is, what is your opinion on using MBO in software development? And if there are development companies using MBO, either successfuly or unsucessfuly.

• Are project managers useful in Scrum?

  - by Martin Wickman

  There are three roles defined in Scrum: Team, Product Owner and Scrum Master. There is no project manager, instead the project manager job is spread across the three roles. For instance: The Scrum Master: Responsible for the process. Removes impediments. The Product Owner: Manages and prioritizes the list of work to be done to maximize ROI. Represents all interested parties (customers, stakeholders). The Team: Self manage its work by estimating and distributing it among themselves. Responsible for meeting their own commitments. So in Scrum, there is no longer a single person responsible for project success. There is no command-and-control structure in place. That seems to baffle a lot of people, specifically those not used to agile methods, and of course, PM's. I'm really interested in this and what your experiences are, as I think this is one of the things that can make or break a Scrum implementation. Do you agree with Scrum that a project manager is not needed? Do you think such a role is still required? Why?

• Choosing the right language for the job

  - by Ampt

  I'm currently working for a company on the engineering team of about 5-6 people and have been given the job of heading up the redesign of an embedded system tester. We've decided the general requirements and attributes that would be desirable in the system, and now I have to decide on a language to use for the system, or at the very least come up with a list of languages with pros and cons to present to the team. The general idea of the project is that we currently have a tester written in c++, which was never designed to be a tester, but instead has evolved to be such over the course of 3-4 years due to need. Writing tests for a new product requires modifying the 'framework' and writing code that is completely non-human readable or intuitive due to the way the system was originally designed. Now, we've decided that the time to modify this tester for each new product that we want to test has become too high and want to partially re-write the system so that we can program the actual tests in a scripting language that would then use the modified c++ framework on the back end to test the actual systems. The c++ framework would be responsible for doing all the actual work and the scripting language would just integrate with that to tell the framework what to do. Never having programmed in a scripting language (we program embedded systems), I've run into a wall where I have no experience with any of the languages that we could possibly use, but must somehow give pros and cons of each language so that we can choose the best one for the job. Currently my short list of possibilities includes: Python TCL Lua Perl My question is this: How can a person evaluate a language that he/she has never used before? What criteria are good indicators for a languages potential usability on a project? While helpful suggestions for my particular case are appreciated, I feel that this is a good skill to possess and would like to be able to apply this to many different projects if at all possible

• Best way for a technical manager to stay up to date on technology

  - by JoelFan

  My manager asked for a list of technical blogs he should follow to stay current on technology. His problem is he keeps hearing terms that he hasn't heard of (i.e. NoSql, sharding, agure, sevice bus, etc.) and he would prefer to at least have a fighting chance of knowing something about them without having to be reactive and looking them up. Also I think he wants to have a big picture of all the emerging technologies and where they fit in together instead of just learning about each thing in isolation. He asked about blogs but I'm thinking print magazines may also help.

• Modify actions when battery is critically low?

  - by Bjarke Freund-Hansen

  I am running ubuntu (not xubuntu!) and am using xfce4 on my laptop. When my laptop battery is critically low, ubuntu/xfce4 performs some action (perhaps hibernate?) which causes my laptop to shut down. However when I start it again, it never comes up. I don't even get BIOS or anything on the screen, it is completely black. The only way to get it back up is to take it apart, remove the internal cmos battery as well as the main battery, wait a few minutes, and put it back together. Obeviously this is not optimal. How do I disable all actions when the battery is critically low? I would rather have it run out of power, than ending up in this error condition. Thanks in advance. :)

• Advice for Setting up an On-Call Team

  - by Ciaran Archer

  I'm leading a largish development team (~35 developers). We are doing primarily Web Development work on a number of sites. Historically the knowledge on the teams has been pretty siloed. If you worked on Site A you will know how to troubleshoot it, but you would not be a lot of help on Site B. We also have a few cross-cutting concerns, i.e. common components used between sites which require specialized knowledge to troubleshoot. With all this in mind, I'm trying to understand the best way to setup an on-call team. This would be a team of programmers who would be available to deal with out-of-hours emergency issues occasionally (say one call every 2 weeks). They may be required to deploy emergency fixes. Part of me is saying we can't have a big on-call team with shallow knowledge, instead we need a smaller team with deep knowledge who can expect to be on-call more often and remunerated as such. Does anyone have any suggestions based on experience on how to setup this team? Thanks in advance.

• Fix Package is in a very bad inconsistent state

  - by Benjamin Piller

  I can't update my system because it freezes while installing a third-party update (zramswap-enabler)!! Sometimes I get the following message in Update manager: Could not initialize the package information An unresolvable problem occurred while initializing the package information. Please report this bug against the 'update-manager' package and include the following error message: E:The package zramswap-enabler needs to be reinstalled, but I can't find an archive for it. I tried to remove the zramswap-enabler, but it's impossible because I get the following message: dpkg: error processing zramswap-enabler (--remove): Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. Errors were encountered while processing: zramswap-enabler E: Sub-process /usr/bin/dpkg returned an error code (1) Actually i would really reinstall that package, but it is unable to do it! If i remove this third-party PPA then the system is warning me about a very very serious problem. So why can i not install/reinstall/remove/update this package and why freezes the updater if i try to update? -S O L U T I O N-: Okay! Finally i found the solution for this Problem! Step 1. Make sure that your PPA is correctly Step 2. Remove the broken package via the following command: sudo dpkg --remove --force-remove-reinstreq zramswap-enabler Step 3. install the package again (sudo apt-get install zramswap-enabler) Step 4. After restart (not necessary) you are able to install the updates correctly! Actually you can fix any "Package is in a very bad inconsistent state” Issues with this solution!!!
