• Gnome shell not starting at login, but can start from terminal (Ubuntu 12.04)

  - by Mat Leonard

  I upgraded to Ubuntu 12.04 recently and for some reason it broke Gnome 3. The shell doesn't start up at login. My .xsession-errors looks like this right after I log in: gnome-session[1689]: WARNING: Session 'gnome' runnable check failed: Timed out (gnome-settings-daemon:1744): color-plugin-WARNING **: failed to get edid: unable to get EDID for output (gnome-settings-daemon:1744): color-plugin-WARNING **: unable to get EDID for xrandr-default: unable to get EDID for output (gnome-settings-daemon:1744): color-plugin-WARNING **: failed to reset xrandr-default gamma tables: gamma size is zero ** Message: applet now removed from the notification area ** Message: using fallback from indicator to GtkStatusIcon ** Message: moving back from GtkStatusIcon to indicator Then I can run gnome-shell --replace, the shell starts up and everything works. This is what I get immediately after: Window manager warning: Log level 16: Unable to register authentication agent: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: An authentication agent already exists for the given subject Window manager warning: Log level 16: Error registering polkit authentication agent: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: An authentication agent already exists for the given subject (polkit-error-quark 0) (gnome-shell:2442): folks-WARNING **: Failed to find primary PersonaStore with type ID 'eds' and ID 'system'. Individuals will not be linked properly and creating new links between Personas will not work. The configured primary PersonaStore's backend may not be installed. If you are unsure, check with your distribution Also, if I run /usr/lib/nux/unity_support_test -p, everything comes back as Yes and this checks out: OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce 8300 GS/PCIe/SSE2 OpenGL version string: 3.3.0 NVIDIA 295.40 It isn't a huge problem since I can get gnome shell to work, but it is a little annoying. So, I'd like to fix this. Thanks for your help.

• Bounding volume hierarchy - linked nodes (linear model)

  - by teodron

  The scenario A chain of points: (Pi)i=0,N where Pi is linked to its direct neighbours (Pi-1 and Pi+1). The goal: perform efficient collision detection between any two, non-adjacent links: (PiPi+1) vs. (PjPj+1). The question: it's highly recommended in all works treating this subject of collision detection to use a broad phase and to implement it via a bounding volume hierarchy. For a chain made out of Pi nodes, it can look like this: I imagine the big blue sphere to contain all links, the green half of them, the reds a quarter and so on (the picture is not accurate, but it's there to help understand the question). What I do not understand is: How can such a hierarchy speed up computations between segments collision pairs if one has to update it for a deformable linear object such as a chain/wire/etc. each frame? More clearly, what is the actual principle of collision detection broad phases in this particular case/ how can it work when the actual computation of bounding spheres is in itself a time consuming task and has to be done (since the geometry changes) in each frame update? I think I am missing a key point - if we look at the picture where the chain is in a spiral pose, we see that most spheres are already contained within half of others or do intersect them.. it's odd if this is the way it should work.

• Diagnosing Bootstrap 3 Glyphicon Button Icons Not Showing

  - by Paulb

  I have a glyphicons in Bootstrap 3. They work very nicely here: latest Chrome latest Firefox latest Safari latest Explorer latest Android At one facility, the glyphicons don't show. The buttons come up blank. How do I troubleshoot? They are security sensitive there. I don't have systems or network access.. and am not in a position to request that. Troubleshooting with advanced tools isn't going to happen. Here's what I have access to: Internet Explorer 9 Behind a very secure firewall Sometimes, I think the glyphs not showing is the IE 9.. but my code should be addressing that. Sometimes, I think their firewall is blocking the CDN. Can I enter a URL into a browser to test if the CDN is there? Sometimes, I think my FB share and like buttons upset this facilty's firewall, and they tie the whole thing down. Any suggestions at how I begin to research this? Or maybe you have an outright idea for IE 9 and glyphs (though my code is very-very close to the demo's which work).

• Another Twig Improvements

  - by Ondrej Brejla

  Hi all! We are here again to intorduce you some of our new NetBeans 7.3 features. Today we'll show you some another Twig improvements. So let's start! Code Templates First feature is about Code Templates. We added some basic templates to improve your Editor experience. You will be really fast with it! If someone don't know what Code Templates are, they are piece of code (snippet) which is inserted into editor after typing its abbreviation and pressing Tab key (or another one which you define in Tools -> Options -> Editor -> Code Templates -> Expand Template on) to epxand it. All default Twig Code Templates can be found in Tools -> Options -> Editor -> Code Templates -> Twig Markup. You can add your custom templates there as well. Note: Twig Markup code templates have to be expanded inside Twig delimiters (i.e. { and }). If you try to expand them outside of delimiters, it will not work, because then you are in HTML context. If you want to add a template which will contain Twig delimiter too, you have to add it directly into Tools -> Options -> Editor -> Code Templates -> HTML/XHTML. Don't add them into Twig File, it will not work. Interpolation Coloring The second, minor, feature is, that we know how to colorize Twig Interpolation. It's a small feature, but usefull :-) And that's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (product php, component Twig). Thanks a lot!

• Thinking skills to be a good programmer

  - by Paul

  I have been programming for last 15 years with non-CS degree. Main reason I got into programming was that I liked to learn new things and apply them to my work. And I was able to find and fix programming errors and their causes faster than others. But I never find myself a a guru or an expert, maybe due to my non-CS major. And when I saw great programmers, I observed they are very good, much better than me of course, at solving problems. One skill I found good in my mid-career is thinking of requirements and tasks in a reverse order and in abstract. In that way, I can see what is really required for me to do without detail and can quickly find parts of solution that already exist. So I wonder if there are other thinking skills to be a good programmer. I've followed Q&As below and actually read some of books recommended there. But I couldn't really pickup good methods directly applicable for my programming work. What non-programming books should a programmer read to help develop programming/thinking skills? Skills and habits to develop to be good at programming (I'm a newbie)

• Windows Randomly Stop Accepting Input from Bluetooth Keyboard

  - by dragonmantank

  I've got a laptop running Ubuntu 11.10 with the most recent updates and an Apple Wireless Keyboard that syncs via bluetooth. The Ubuntu box is also a Synergy server, using QuickSynergy to run Synergy. I'm using xmodmap to swap the option and command keys, but nothing else. Throughout the day, windows that are long running will just stop accepting input. For example, I leave gnome-terminal up and running almost 24 hours a day. If it sits for a while, it just stops accepting input. It doesn't matter if I'm ssh'd into another machine or sitting on a local tty session, it just stops accepting input. If I open a new tab or window, those work fine. The 'broken' tabs stay broken. I'm also running Turpial (a Twitter client) which will do that same thing. I tend to use the arrow keys to navigate, and it just stops accepting input. Closing it and reopening it causes it to work fine. I don't seem to have the problem in Chrome, but I tend to open up new tabs when I go somewhere instead of using existing tabs. I've updated all the packages, rebooted, and the only thing that seems to cure it is if I type on the built-in keyboard, the window will start to accept text from the bluetooth keyboard (until it stops again). I don't think the keyboard is disassociating from the laptop because it can happen while I'm using the keyboard, it seems more linked with windows that I sit for a long time. As an example, I'm typing in Chrome with the bluetooth keyboard but I have a terminal window that won't accept input.

• Managing arbitrary user permissions under PureFTPd

  - by Sebastián Grignoli

  I need to provide an FTP service that needs to be web-managed in the simplest way possible. My customer wants to create folders and users, and give them read only or read/write access arbitrarily. For example: The folder 'Documents' should be read only for several users, writable for internal users, and invisible for the rest. The folder 'Pictures' should be read only for journalists, writable for associates, and invisible for the rest. The folder 'Media' should be read only, writable or invisible for arbitrary users specified on the admin. There could be a large number of users and folders. I can't find a good way to accomplish that. I thought that I could give each user a home folder and put symlinks for the folders he has read access to, and make the user part of the folder's group when he has write access too, but now I think that this wouldn't work, because with PureFTPd (or ProFTPd) I can only specify the virtual user's mapping to a system user, and only one GUID for each virtual user. My approach requires that I could specify several GUIDs for each user (one by each folder he has write access to). I need to start programming this admin and I still don't know wich approach would work, if any. ¿Any ideas?

• How to apply verification and validation on the following example

  - by user970696

  I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)

• Ubuntu 12.10: Installing proprietary Nvidia driver causes freeze at boot

  - by Greg

  Ok, so I just installed Ubuntu on my laptop, and I immediately encountered an issue: the HDMI audio output won't work. Yes, I know about the sound settings thing where you have to select the HDMI option, but even when it's selected I get no sound out of the TV I'm hooking it up to. This is a dealbreaker for me, because my laptop speakers are terrible, it's one of the big reasons I use my TV monitor. So I decided to work on solving the problem by upgrading my Nvidia drivers. I switched to one of the propriety drivers offered in that software updating utility that comes with the OS, the one option that said (tested). Viola, sound over the HDMI is now working. Unfortunately, this now brings me to my next problem: when I reboot Ubuntu with this or any other proprietary driver installed, it freezes when it tries to load my desktop. As in I can see my wallpaper, but no icons or options of any kind. The system is totally frozen, and gives me one of those "we've experienced an error, do you want to report it messages." So there's my bind. I need HDMI audio out, that's a total dealbreaker for me, but installing the drivers that give me that capability crash the system. Does anyone have any idea what's causing this

• Rant - Why is Windows Azure not available in Africa?

  - by Allan Rwakatungu

  Yesterday at the .NET user group meeting in Kampala Uganda  I gave a talk on cloud computing with Windows Azure  (details will be in my next blog post). The guys where excited. Without owning they own inftrastucture and at low cost they can build scalable , highly available applications. Not quite. Azure accounts are only available to people in particular countries - none from Africa. I attended PDC in 2008 when Microsoft unleashed Windows Azure. One of the case studies to show the benefits ofr cloud computing was a project in Africa for an education service in Ethiopia. The point they where making was that the cloud was perfect for scenarios where computing infrastructure is not sophiscated, like Ethiopia. Perfect , i thought. So i got my beta account from PDC and started playing around in the cloud. Then Azure goes live , my beta account does not work any more and I cant pay because am from Uganda. Microsoft , this sucks. I dont know the reasons for Microsoft doing this, but am sure we can work out something. We in Africa need the cloud more than anybody else in the world. Setting up data centers that are higly scalable and available for our startups is not an option we have. But we also cant pay for cloud computing with Microsoft. Microsoft, we know we are a tiny insigficant market for a company your size, but your excluding us only continues to widen the digital divide. Microsoft , how about you have a reseller model for cloud computing. Instead of trying to deal direclty with each client you have local partners who help you sell and bill your cloud services. I think that would lead to Windows Azure being available in Africa. I can help you resell in Uganda.

• Fix for poor hd playback for 11.04 upwards

  - by mark kirby

  Hi guys ive seen loads of posts on this site about poor 720/1080p playback in recent ubuntu versions I had this problem and fixed it so I thought id share it with everyone.... 1 install mplayer 2 install smplayer frontend {in software center} 3 open smplayer 4 go to "OPTIONS" then "PREFRENCES" then "GENRAL" 5 if you have a nvidia card choose "OUTPUT DRIVER" and select "VDPAU" {for ATI or AMD choose xv (0 - ATI Radeon AVIVO video) I dont know if this will work as my card is nvidia but it should) 6 go to performance on the left hand side and set both local and streaming cache to 99999 (this may also fix dvd playback if you set that cache aswell} 7 check the box for "ALLOW HARD FRAME DROP" and set "LOOP FILTER" to skip only on HD 8 Set the "THREDS FOR DECODING OPTION TO THE NUMBER OF CORES YOUR CPU HAS IF YOU HAVE MORE THAN ONE CPU ADD UP ALL THE CORES FOR BEST PERFORMANCE" 9 Enjoy you HD movies again on ubuntu...... I have a pretty avrage machine heres my spec.... 2x Pentium 4 ht 3 ghz Stock dell power and motherboard GFORCE 310 HDMI 24 inch full HD tv as a monitor so any one with dule core cpu should have no problems getting this to work. hope this helps someone out.

• Fn key sticks down

  - by Oli

  Just bought my significant other a shiny new Samsung Q330 13" netbook, stuck an OCZ Agility in it and installed Maverick. Just as a quick aside, this is a devastating combination. Graphics work perfectly and it cold-boots to desktop in about 7 seconds. Very quick. But (common to laptops) I've got a couple of problems. I'll start with the most problematic and start a new thread for the other. Like a lot of laptops, there is a Fn (function) modifier to allow some keys to have another purpose. When I tried to alter the brightness of the screen by tapping Fn+Down, it worked but kept on going until it was as dim as it could go. I tapped Fn+Up and it went to the other extreme. After that the entire keyboard ceases to work properly because the Fn modifier appears to be locked. Additionally, and as a direct side effect, I think, clicking on things doesn't result in a standard result. It's as if control is being held. A reboot is the only thing that seems to fix these problems. This isn't a problem if you don't touch the Fn key but as there are two of them on the keyboard, an accident is going to happen sooner than later, requiring a reboot (and probably some data loss). I don't have a lot of experience with laptops (I prefer my hulking great desktop) so this isn't my area of expertise. I'm open to all suggestions, even disabling the two Fn keys until we can find a better solution.

• Mocking concrete class - Not recommended

  - by Mik378

  I've just read an excerpt of "Growing Object-Oriented Software" book which explains some reasons why mocking concrete class is not recommended. Here some sample code of a unit-test for the MusicCentre class: public class MusicCentreTest { @Test public void startsCdPlayerAtTimeRequested() { final MutableTime scheduledTime = new MutableTime(); CdPlayer player = new CdPlayer() { @Override public void scheduleToStartAt(Time startTime) { scheduledTime.set(startTime); } } MusicCentre centre = new MusicCentre(player); centre.startMediaAt(LATER); assertEquals(LATER, scheduledTime.get()); } } And his first explanation: The problem with this approach is that it leaves the relationship between the objects implicit. I hope we've made clear by now that the intention of Test-Driven Development with Mock Objects is to discover relationships between objects. If I subclass, there's nothing in the domain code to make such a relationship visible, just methods on an object. This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I can't figure out exactly what he means when he says: This makes it harder to see if the service that supports this relationship might be relevant elsewhere and I'll have to do the analysis again next time I work with the class. I understand that the service corresponds to MusicCentre's method called startMediaAt. What does he mean by "elsewhere"? The complete excerpt is here: http://www.mockobjects.com/2007/04/test-smell-mocking-concrete-classes.html

• White screen with pointer after removing Unity

  - by Sameer Pandit

  I have the same problem . I am a newbie. I added the repository with sudo add apt-get-repository ppa:canonical-dx-team/une then i went to ubuntu software center and installed "unity interface of ubuntu netbook edition" . after installing i found a problem with User interface as it kept on flashing when mouse points to side panel . so i decided to remove it . I removed it form Ubuntu software center . there were other unity related apps installed , but i did not remove then as i had no idea what they were about . Now i ended up with a blank white screen with mouse pointer whenever i login. though i m able to login using gdm , but the screen is blank white. I tried to these commands also sudo apt-get remove gnome-shell sudo apt-get remove unity sudo restart gdm but they did not work at all i also tried sudo dpkg-reconfigure xserver-xorg it too did not work. Note:I donot have any sort of graphics card or video card on my pc please help !!!

• Location of development solutions on disk - Common or upto the individual

  - by dreza

  In our team meeting today a senior member brought up the proposal that we should be having a common location/structure for our development solutions. A couple of his points were: Making it common meant when talking about projects and emailing stuff everyone is on the same wavelength and knows where to look. If there is ever the need to hard code a location path then it will work across all developers pc's. He had a more few points to back up his suggestion but I unfortunately got distracted during the discussion and so didn't hear all of them. I have no issue with the idea and can see it's merits but I was wondering if it is common or even recommended that all developers place their code in the same folder structure. Or do developers like to have the flexibility of location solutions where-ever they want? We currently use SVN for our version control. In this case his recommendation was to place all code in: c:\Work\Development\<Customer>\<project>\Code\<solution>\ the code I guess actual path is irrelevant for this question but added for completeness.

• Software Center empty "No usefulness from server" "no username in config file"

  - by Theron G. Burrough

  I upgraded to 12.04 LTS and ran Software Center while a few things were running, and crashed. (2 GB RAM on a Netbook.) On reboot, Ubuntu One interface would not find any programs, neither installed (to run) nor available for download. So I launched Software Center, which opens, but does nothing. I click "Close" button and get a "Force Quit?" box. So I quit. Did research, learned to run Software Center from Terminal: 2012-04-29 23:14:36,978 - softwarecenter.backend.reviews - WARNING - Could not get usefulness from server, no username in config file Then tried the below without success: Reinstallation of software center: sudo apt-get install --reinstall software-center Didn't work. Found this in a post: remove the config file for software-center then log out and back in sudo rm -rf ~/.config/software-center Didn't work. Reinstalled Software Center with Synaptic Package Manager. Still no dice! And I am a Linux newbie, so I don't know where the Dickens that config file is. Help appreciated.

• Dell Mini 9 Integrated Microphone -- not working

  - by Josh Eismanaf

  Im running the latest Debian version, 6.0 on my Dell Mini 9.Webcam and sound work, but microphone is a no-go. I hope even though it is Debian, fellow Linux users can help. In Alsamixer (1.0.23), I have Capture, Digital, and Mic settings all the way up. There are no options for adjusting "Front" mic settings. (May have been for older alsamixer versions?) In Sound Recorder, playback has loud noise/feedback? Under Preferences in Volume Control under the Recording tab, both Capture and Digital are permanently checked, regardless if I uncheck them. I'm not sure how to interpret the above, but I am just trying to offer as much relevant background information as I can. I've been scouring forums for the answer, but to no avail. Most questions/answers are from 2008, and couldn't find a solution. I'm not very handy with the Linux machine, but love to learn / am learning. Also, I've attempted the solution here, and it didn't work. Thanks, in advance, for your help!

• Remote Debugging

  - by Pemdas

  Obviously, the easiest way to solve a bug is to be able to reproduce it in house. However, sometimes that is not practical. For starters, users are often not very good at providing you with useful information. Costumer Service: "what seems to be the issue?" User: "It crashed!" To further compound that, sometimes the bug only occurs under certain environmentally conditions that can not be adequately replicated in house. With that in mind, it is important to build some sort of diagnostic framework into your product. What type of solutions have you seen or used in your experience? Logging seems to be the predominate method, which makes sense. We have a fairly sophisticated logging frame work in place with different levels of verbosity and the ability to filter on specific modules (actually we can filter down to the granularity of a single file). Error logs are placed strategically to manufacture a pretty good representation of a stack trace when an error occurs. We don't have the luxury of 10 million terabytes of disk space since I work on embedded platforms, so we have two ways of getting them off the system: a serial port and a syslog server. However, an issue we run into sometimes is actually getting the user to turn the logs on. Our current framework often requires some user interaction.

• xorg-edgers PPA with llvmpipe breaks AMD APU system

  - by linux_RRT

  I've read before where this had happened to another user with the same system... I was running Ubuntu 12.04 LTS with Kernel 3.2.0.29 and decided to give xorg-edgers a try. I purged fglrx* and xorg* before beginning. I upgraded with sudo apt-get upgrade -d The system downloaded and installed 109MB worth of data to the system, including llvmpipe which I am very unfamiliar with, and Kernel 3.5.0.11. The system was then rebooted to finalize the upgrade. The system boots to a black screen and then tells me "The system is running in low-graphics mode". Did I miss a step in the install? Or do the newest open-source drivers just not work with my hardware? I realize this hardware (APU) is some of the newer development. I dropped to command via the fallback menu and attempted to boot lightdm as root, but the system hangs in 'Configuring kernel parameters' at Starting initializes zram swaping. ...and then it just sits there. The other thing that concerns me is the output at the top of the screen that says: could not write bytes: Broken pipe Does llvmpipe work for this type of system? To be clear the system is: MSI x370-206us Laptop Radeon HD 6320 AMD e450 APU 1.67ghz dual-core Any help would be much appreciated. Like I said, I'm pretty sure I followed the right order of operations for the install procedure, but I was curious if anyone with similar hardware had experienced anything similar.

• Ubuntu 12.04LTS stuck at login mouse and keyboard not responding

  - by user169954

  I have Ubuntu 12.04LTS installed on a dual-booted machine (i5 dual core 8G ram) and it's been working fine, but today for some reason when I logged out and tried to log back in it is stuck at the login page, i.e. the mouse and the keyboard are not responding. The mouse is stuck at the top left corner of my screen, and I can do nothing but to turn the machine off. (I have been using logitech wireless mouse and keyboard.) I can not access the virtual console (Alt-F1 or Cntrl-Alt-F1) either! Here is what I have tried so far: Verified it is not a H/W problem since the mouse and keyboard work fine with windows7 Booted with ubuntu installation dvd and ran trial mode and mouse and keyboard worked fine. Tried bypassing the login screen by booting into recovery mode and editing tty1.conf, but to no avail. I moved .Xauthority .profile and .bashrc from my $HOME to another location so my login would proceed completely by system defaults. But this did not help From recovery mode commandline used to dpkg-reconfigure to switch between gdm and lightgdm. This did not help either. By the way, when in recovery mode as root from command line I mount the filesystem, all apps work fine. Python is Ok, octave is ok, vi is ok etc. I have a feeling if I could only bypass the login screen, and automatically get into the desktop, I will be ok. But I haven't been able to accomplish this either. I desperately need help please. Thank you in advance. Update: So I tried to switch to lightdm by dpkg-configure lightdm. This at least brings me up to the classical linux commandline login prompt but without a gui. Should I install startx? Should I install ubuntu-desktop?

• Can DVCSs enforce a specific workflow?

  - by dukeofgaming

  So, I have this little debate at work where some of my colleagues (which are actually in charge of administrating our Perforce instance) say that workflows are strictly a process thing, and that the tools that we use (in this case, the version control system) have no take on it. In otherwords, the point that they make is that workflows (and their execution) are tool-agnostic. My take on this is that DVCSs are better at encouraging people in more flexible and well-defined ways, because of the inherent branching occurring in the background (anonymous branches), and that you can enforce workflows through the deployment model you establish (e.g. pull requests through repository management, dictator/liutenant roles with their machines setup as servers, etc.) I think in CVCSs you have to enforce workflows through policies and policing, because there is only one way to share the code, while in DVCSs you just go with the flow based on the infrastructure/permissions that were setup for you. Even when I have provided the earlier arguments, I'm still unable to fully convince them. Am I saying something the wrong way?, if not, what other arguments or examples do you think would be useful to convince them? Edit: The main workflow we have been focusing on, because it makes sense to both sides is the Dictator/Lieutenants workflow: My argument for this particular workflow is that there is no pipeline in a CVCS (because there is just sharing work in a centralized way), whereas there is an actual pipeline in DVCSs depending on how you deploy read/write permissions. Their argument is that this workflow can be done through branching, and while they do this in some projects (due to policy/policing) in other projects they forbid developers from creating branches.

• I know how to program, and how to learn how to program, but how/where do you learn how to make systems properly?

  - by Ryan

  There are many things that need to be considered when making a system, let's take for example a web based system where users log in and interact with each other, creating and editing content. Now I have to think about security, validation (I don't even think I am 100% sure what that entails), "making sure users don't step on each others feet" (term for this?), preventing errors in many cases, making sure database data doesn't become problematic through unexpected... situations? All these things I don't know how or where to learn, is there a book on this kind of stuff? Like I said there seems to be a huge difference between writing code and actually writing the right code, know what I mean? I feel like my current programming work lacks much of what I have described and I can see the problems it causes later, and then the problems are much harder to solve because data exists and people are using it. So can anyone point me to books or resources or the proper subset of programming(?) for this type of learning? PS: feel free to correct my tags, I don't know what I am talking about. Edit: I assume some of the examples I wrote apply to other types of systems too, I just don't know any other good examples because I've been mostly involved in web work.

  Topeka DNUG is free for anyone to attend! Mark your calendars now! SPEAKER: Troy Tuttle is a self-described pragmatic agilist, and Kanban practitioner, with more than a decade of experience in delivering software in the finance and health industries and as a consultant. He advocates teams improve their performance through pursuit of better practices like continuous integration and automated testing. Troy is the founder of the Kansas City Limited WIP Society and is a speaker at local area groups on team related topics. He currently works as a Project Lead Consultant with AdventureTech Group of Kansas City, KS. TOPIC: Why Kanban? Kanban is receiving a large amount of attention recently. What does it offer compared to other approaches? Answering that question may require you to hit the “reset” button on previously held biases and assumptions. Kanban blends Lean thought with ideas from first generation agile methodologies. To get started with Kanban, we will examine what steps are necessary to establish a transparent, work-limited, pull system.

• Working Abroad Advice Needed

  - by RBA

  Hi, First of all, Happy New Year everybody! I wish you for 2011 all the best! For several years I was thinking about to work abroad, and I want to make this step(to work in a/several foreign countries, for several years). I am a Software Developer with a Bachelor of Engineering in Computer Science, with a +4 years of experience in Delphi(and small working experience in other programming languages). Until now I've applied at aprox. 100 positions over the world, and I've been contacted by 4-5 hiring managers. Our technical discussions went good, but then we reached at working visa 'problem'. I don't have legal/health problems, but I don't poses a working permit in other countries except Romania. I've been reading several forums concerning the working visas (here I take out working visa for US or other 'hard to get visa' countries), and there are several steps which companies must do (so I can take out the bureaucracy problem) to make the papers. Concerning the cost of a visa, this goes up to one medium salary from that country(in most of the cases). I've been working for the last years with different clients, from a wide variety of countries, and I don't believe I will have problems with integration in a foreign country So, the problem is that the market don't need Delphi Developers (there is a small amount of open positions on the recruiting sites), and I should start learning other programming language(all the time is better to know other programming languages - but to master it, requires some time) with a higher market 'rank' (Java/C#/etc), OR the problem is only concerning the working visa, and maybe the reticence of the employer to foreign possible candidates? I'm asking this especially for those users who made this step in their life or they want to make it in the future. Best regards,

• How to manage and estimate unstructured requirements received from customers

  - by user20358

  A lot of the times I receive a software system's requirements from our customers in a very unstructured format. It is usually a bunch of "product development" guys from the customer's who come up with these "proposed solutions" to the business problems they have. While they are the experts at the business domain, a lot of the times they don't have the solutions right. This results in multiple versions of the same requirement mixing up of two requirements into one a few versions of the requirement later down the line, the requirements which were combined together get separated out again, each taking with it some of the new additions How do you work with such requirements coming in and sort them out into proper use cases and before development begins? What tools can we use to track a particular requirement's history, from the first time it was conceived till the time it gets crystallized into a proper use case? Estimating work against requirements received in such a fashion is a nightmare which ends up in making mistakes in understanding the requirement correctly and estimating the effort against it correctly. Any tips, tools, tricks to make this activity more manageable? I'm just trying to get some insights from someone more experienced than I am in requirements management and effort estimation.
