• Ubuntu 12.04 Network Manager: unable to save manual setting to set up a static ip

  - by Andy

  I am fairly familiar with setting up servers, and ubuntu is generally my flavor of choice, but I just installed 12.04 desktop and I am seeing some behavior in network manager that is really puzzling. The network connection works fine if I leave it set on dhcp, but I would like a static IP address for my new web server. When I go into network manager and edit the connection for the one and only NIC I can select MANUAL from the dropdown menu but as soon as I do the Save button becomes greyed out. Even after filling out all fields for the connection it is still grey and I am unable to save the static IP connection information. Any thoughts would be greatly appreciated. I'm hoping there is just some new setting that I am unaware of.... On another note, if I stop the network manager and go edit the interfaces file (and the appropriate hosts/routes/dns files), I do get a static ip address assigned and I can contact my server from the outside, however, the server cannot find the internet. Can't ping even its own ip... I can ping the loopback interface though. I'm really confused on this one. Hoping someone can offer some help.

• Entry level engineer question regarding memory mangement

  - by Ealianis

  It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the ladder and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question. "Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub)." I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?

• When can you call yourself good at language X?

  - by SoulBeaver

  This goes back to a conversation I've had with my girlfriend. I tried to tell her that I simply don't feel adequate enough in my programming language (C++) to call myself good. She then asked me, "Well, when do you consider yourself good enough?" That's an interesting question. I didn't know what to tell her. So I'm asking you. For any programming language, framework or the like, when do you reach a point were you sit back, look at what you've done and say, "Hey, I'm actually pretty good at this."? How do you define "good" so that you can tell others, honestly, "Yeah, I'm good at X". Additionally, do you reach these conclusions by comparing what others can do? Additional Info I have read the canonical paper on how it takes ten-thousand hours before you are an expert on the field. (Props to anybody that knows what this paper is called again) I have also read various articles from Coding Horror about interviewing people. Some people, it was said, "Cannot function outside of a framework." So they may be "good" for that framework, but not otherwise in the language. Is this true?

• Implementing AS 2.0 with FSM?

  - by Up2u

  i have seen many of references of AI and FSM like : http://www.richardlord.net/blog/fini...n-actionscript and sadly im still can't understand the point of the FSM on AS2.0 is it a must to create a class of each state ? i have a project of game and also it has an AI, the AI has 3 state n i said the state is distanceCheck, ChaseTarget, and Hit the target, the game that i create is FPS game and play via by mouse so what i mean is i have create an AI ( and is success ) but i want to convert it to FSM method ... i create : function of CheckDistanceState() and in that function i have to locked the target with an array, and sort it with the nearest distance and locked it and it trigger the function ChaseState(), and in the ChaseState() i insert the Hit() function to destroy the enemy, the 3 function that i created , i call it in the AI_cursor.onEnterframe, ( FPS game that only have a cursor in stage ) is there any chance to implement FSM to my code without to create a class ?? from what i read before , to create a class mean to create an external code outside of the frame ( i used to code in frame) and i stil dont understand about it. sorry if my explaination not clear ...

• New Horizon

  - by alexismp

  I have resigned from Oracle and thus will soon leave the GlassFish group. I feel very proud looking back at what we've achieved as a team with GlassFish in the past few years, including those past two years at Oracle. If you know anything about the history of application servers at Sun, you'll recognize that building such a community around GlassFish and its amazing number of downloads is nothing short of a small miracle. The Java EE platform has also seen a strong resurgence, bringing it back to the forefront of effective enterprise Java development in many ways. Having been hired by Sun some 13 years ago to sell NetDynamics I certainly feel that I leave the company's application server in *much* better shape. Oracle has ambitious plans for GlassFish and has been in my opinion a good steward for this community. I see no reason for this to change and I do expect the community to keep on pushing Oracle to get even better with time. This ride has been intense and the people I've met and worked with, both inside and outside Sun/Oracle, have made the experience the best one of my career. My journey now continues here: alexismp.wordpress.com. See you there!

• Toolset agnostic build server and Silverlight projects

  - by Marko Apfel

  Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\WebApplications\Microsoft.WebApplication.targets" /> And now Visual Studio Conversion Wizard welcomes my with this: Solution Regardless of which line I write – this conversion comes back again and again, if the line has another form than <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So it seems that there is no simple way to change this behaviour. Workaraound I must accept, that this line must be in the csproj and to run the build the toolset must be copied to the build server at the correct location. So go to your development machine where Visual Studio is installed and copy the folder “C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications” to your build server at the equivalent location.   Xmas wishes to Microsoft: Please provide technologies to let us developers bundle all needed stuff for a project in one developer tree. It should be possible that one checkout starts us up! No additional installations regardless whether it is a developing machine or dedicated build or continuous integration server. Silverlight is only one example, code analysis configurations could also be terrible and much more …

• So my employer wants me to do less programming and focus on IT support

  - by Rich

  I was hired into a non tech company's IT department as a programmer a few years back, and after several rounds of lay offs, we're down to a skeleton crew. I've saved the company hundreds of thousands of dollars with my projects and management has been happy with them (although most of the stakeholders have since left the company). Management now wants me to limit the programming that I do and spend most of my time on IT support: putting out fires, dealing with vendors, outsourced contractors, supporting company systems, managing projects, etc. I am a little burnt out on programming since I've been pushed pretty hard for the past several years. However, I'm not sure if this is a good career move in the long run. I'm a decent programmer (and also good with databases) but not obsessed with it to the point of coding outside of work. I'm approaching my mid 30s and there's potential ageism to deal with down the line. While I'm fortunate to have survived the lay offs, it sorta feels like my job is being "dumbed down". I have both good technical skills and people skills...but it doesn't take a genius to do what I'm doing now. And my success is being increasingly linked to others' performance rather than my own... Just looking for some advice. Is it time to move on? That's not really an easy thing to do since I'd likely have to move to another area to find another comparable tech job. Should I go after another pure technical role? Or should I stay and try to make this work? People say do what you "enjoy" but it doesn't really matter to me as long as I'm getting paid. Also the ageism thing is on the horizon and could be an issue eventually. I'm making a decent (but not great) salary. Should I chase money and maximize my income while I still have a chance? Or be happy with a moderate salary and 40 hour work week?

• Photos being copied all over the place

  - by plua

  We have a rather popular website with plenty of photos. Our whole business depends on our content - and the photos are important in this. We invest a lot of time, effort, and money into taking these pictures. On our website we have clear copyright notices, we have the website name and logo in the photos, and we have a Photo Licensing page which states the prices of licensing our photos. Despite all this, our photos are copied by personal and commercial websites alike. We really want to do something about this. We do not want them to take out the photos and leave it at that. We want them to pay for the usage, as we clearly state on our website. Now a few questions come to mind: Can we legally force them to pay right away? Or are we obligated to first write a "Cease and Desist" letter? Photos are used on websites throughout the world. Are there any worldwide rules for this? Has anybody experience with doing these things outside of their home country? Should we hire a lawyer in any country? Or could a local lawyer contact oversees companies directly?

• Is it possible to have multiple subdomains point to the same Blogger blog?

  - by cclark

  For our application we want to have a status page which is hosted outside of the rest of our infrastructure so in case there are issues in our data center we can post updates for our users and our users will be able to access them. We registered a blog on Blogger and set it up with xyzstatus.blogspot.com and status.xyz.com. Everything seems to work fine. We need to perform some maintenance at our datacenter which will sever all connectivity so we're unable to have a redirect using nginx or apache. We'd like to do this with a short TTL CNAME DNS entry. Ideally www.xyz.com and app.xyz.com could be CNAMEd to status.xyz.com. When I setup the CNAME and go to that URL I get a Google broken robot 404 page. I figure I must need to let Google know it should associate traffic to www.xyz.com and app.xyz.com to the blog served up by status.xyz.com. But I can't see anywhere to do this in Blogger. Does anyone know if this is possible?

• UnsatisfiedLinkError: no swt-gtk-4233

  - by Abogical

  I'm a Java newbie who just a made a simple Java program using SWT for GUI via eclipse Juno. The code was working and the program was able to run inside eclipse, so I compiled it and made it a runnable jar file so it can be run outside eclipse. I tried to run it using the terminal and this error came up. Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-gtk-4233 in java.library.path no swt-gtk in java.library.path Can't load library: /home/abody/.swt/lib/linux/x86_64/libswt-gtk-4233.so Can't load library: /home/abody/.swt/lib/linux/x86_64/libswt-gtk.so at org.eclipse.swt.internal.Library.loadLibrary(Library.java:331) at org.eclipse.swt.internal.Library.loadLibrary(Library.java:240) at org.eclipse.swt.internal.C.<clinit>(C.java:21) at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java:63) at org.eclipse.swt.internal.Converter.wcsToMbcs(Converter.java:54) at org.eclipse.swt.widgets.Display.<clinit>(Display.java:133) at Class1.main(Class1.java:12) So now it looks like it can't find "libswt-gtk-4233.so" and the other file. However, when I took a look at he ".swt" folder I had an "libswt-gtk-3740.so" not 4233. So its trying to find a file that is more up-to-date. So what does that mean, should I update SWT? what's going on?

• I have an "amoeba" game mechanic. Any idea on how to implement it?

  - by Jason

  Outside of a tetris clone, a crappy 2D top-down shooter, and some messing around with stuff like Unity and Flixel, I realize that I have yet to complete a single, polished, bells-and-whistles game. I want to change this, and I have an idea for my next project. The idea is that you're an amoeba. Amoebas have these eye-like cores (or something like that, I don't know biology), and you have two of 'em. You control one with WASD and the other with IJKL. There has to be a constant radius of stuff around each of the cores: And the area of the amoeba has to stay constant. So if you move a core in one direction, you increase the amoeba's area, but that increase is compensated by a decrease somewhere else: Aaaaaand I'd like to implement a vagination mechanic. You absorb things by engulfing them, like a boss. Maybe even an extra core, or a needle that pops you and causes all your inner stuff to start gushing out: But here's the problem: I don't know how to make this. However, I would like some ideas on how to implement it. Should I explore physics libraries like Box2D? Or maybe something involving fluid physics? Any help would be much appreciated. P.S. Feel free to steal this idea. I have plenty of ideas. If you do, please tell me how you made it so I can try it myself.

• The advantages & disadvantages to be had from using a Web Framework?

  - by JHarley1

  Hello, This question is focused on extracting the advantages and disadvantages of using Web based Frameworks: such as Cake PHP, Zend, jQuery, ASP.NET). This question is completely language agnostic. Let me start with the notion of "Standing on the shoulders of Giants". Advantages: Empowers Developers - by taking features that would have previously have taken 100's of lines of code and compressing them into one simple function call empowers developers to integrate more complex features into their Web Sites. Allow for Quicker development of applications - this is very relevant for people that need websites created in a very small window (has anyone any examples of this?) Lower Costs - allows programmers to pass cost savings onto the customer, a whole new range of customers generated that wanted a website but previously could not afford the higher development costs. Disadvantages: Lost Understanding - by relying on the features of a framework a developer is in danger of loosing understanding on how things work (underneath the hood). The configuration cliff - once you go further than the configuration of your framework your productivity drops right off, it can be difficult to implement features outside of a frameworks configuration. Developer tramlines - you (the developer) has to do things the way that the developer want you to do things. Security issues - giving people these tools to develop professional looking websites fast is a potential risk, people can quickly create professional looking websites for fraudulent companies. I wonder what people make of my points, and whether any body disagrees with them? Also if people have additional points I would be grateful. Many Thanks, J

• Natural talent vs experience [on hold]

  - by Tord Johansson Munk

  Hi i have a question for you guys if you had a choice of hiring one of two programmers. One of them is a natural born programming talent, he has been programming since he was 14 year old and he has been programming all sorts of things by him self, 3d renders,games,his own frameworks, he is really good at algorithms and problem solving. He is now about 25 years old and is looking for a job after some unchallenged years of college the only experience he has is working on his own/university stuff and some open source project. This guy spends all his free time programming and has several pet projects at home. The other person is a 37 year old career programmer. He has been programming since he graduated from university at the age of 26 and have been working since then. He did not have an interest in programming before university. During his studies he discovered that programming was fun and challenging but it never was a "passion". During his career he mainly worked with "enterprise" platforms such as .net or javaEE. He mainly have done database business applications and thus is lacking skills of the young talent like abstract problem solving or algorithms. But he know the tools he has been using during the years and is reliable and almost always makes his boss happy. He keeps him self updated in the platform and tools he has and is using. But outside the office walls he don't touch any code at all. Witch one would you hire? Would you favor one of them in certain projects? Do you think that if the young talent learns his tools he will be a better programmer than the older one? Would your decision be different if both of them where lacking a degree? or if only one of them was lacking a degree be the old and experienced or the young genius.

• Should I expect my peers to read or practice on a regular basis? [closed]

  - by Joshua Smith

  I've been debating asking this question for some time. Based several of the comments I read in this question I decided I had to ask. This feels like I'm stating the obvious, but I believe that regular reading (of books, blogs, StackOverflow, whatever) and/or practice are required just to stay current (let alone excel) in whichever stack you use to pay the bills, not to mention playing with things outside your comfort zone to learn new ways of doing things. Yet, I virtually never see this from many of my peers. Even when I go out of my way to point out useful (and almost always free) learning material, I quite often get a sense of total apathy from those I'm speaking to. I'd even go so far as to say that if someone doesn't try to improve (or at least stay current), they'll atrophy as technology advances and actually become less useful to the company. I don't expect people to spend hours a day studying or practicing. I have two young kids and hours of practice simply aren't feasible. Still, I find some time; perhaps on the train, at lunch, in bed for a few minutes, whatever. I'm willing to believe this is arrogance or naivete on my part, but I'd like to hear what the community has to say. So here's my question: Should I expect (and encourage) the same from my peers, or just keep my mouth shut and do my own thing?

• Finding the best practice for a game simulating tool

  - by Tougheart

  I'm studying Java right now, and I'm thinking of this tool as my practice project. The game is "League of Legends" in case anyone knows it, I'm not actually simulating the game as in simulating game play, I'm just trying to create a tool that can compare different champions to each other based on their own abilities and items bought inside the game. The game basics are: Every player has a champion in a team of 5 players playing against another team. Each champion has a different set of abilities (usually 4) that s/he uses to do damage to opposing champions. Each champion gets stronger by buying different items, increasing the attack it deals or decreasing the damage received. What I want to do is to create a tool to be used outside the game enabling players to try out different builds for their champions and compare the figures against other champions they usually fight against. The goal is to enable players get a deeper understanding of the different item combinations (builds) that can be used during the games, instead of trying them out in real games which can be somehow very time consuming. What I'm stuck at is the best practice I should follow to make this possible using Java, I can't figure out which classes should inherit from which, should I make champions and items specs in the code or extracted from other files, specially that I'm talking about hundreds of items and champions to use in that tool. I'm self studying Java, and I don't have much practice at it, so I would really appreciate any broad guidelines regarding this, and sorry if my question doesn't fit here, I tried to follow the rules. English isn't my native language, so I'm really sorry if I wasn't clear enough, I would be more than happy to explain anything that's not understood.

• Init.d script gets return code 1 when calling itself, how can I get output?

  - by Per

  My question is, how can I modify the script so that it will tell me what goes wrong? The scenario is this: I'm trying to get Sonatype Nexus to start as a service in Ubuntu 10.04, and it just will not work. (I'm not looking for help on how to run Nexus, but on how to get some useful output from a script) It works when invoking it with sudo /etc/init.d/nexus start but fails when using sudo service nexus start I have run the update-rc.d command on it, and done everything according to instructions. The nexus init.d-script has a point where it calls itself when it detects that it should run as another user ('nexus'): su -m $RUN_AS_USER -c "\"$REALPATH\" $2" which expands to su -m nexus -c '"/opt/nexus-2.0.2/bin/jsw/linux-x86-64/nexus" start' when adding the -x debug flag to the script. This command results in return code 1. It never executes - I've set -x debug flag on the script, placed echo commands with redirect to file at the start of script to trace, etc. I cannot get any output telling me why the command will not execute. I've tried appending redirect to file after the above script line, inside the quotes, outside, any way I could imagine. All info I can get is by inserting a line echo $? after the su line, which outputs '1'. Is there a way I can see what happens when the su command runs?

• TFS API The All New Team Project Picker &ndash; Beautiful!

  - by Tarun Arora

  The Team Project Picker in TFS 2011 looks gorgeous. I specially like the status bar on the working state, at least let’s you know that the project picker is still working on getting the details and of course the new icons for team project collection and team projects are stunning too.     How do I get the Team Project Picker using the TFS API? That is fairly straight forward. Add a reference to the Microsoft.TeamFoundation.Client dll available in C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0 and use the below code, public void ConnectToTfs() { TeamProjectPicker tfsPP = new TeamProjectPicker(TeamProjectPickerMode.MultiProject, false, new UICredentialsProvider()); tfsPP.ShowDialog(); }   Download a sample application here Why does my project picker look different? You might run into an issue, where the project picker looks like the below, When the Team Project Picker is run from inside of VS the colour theme will be picked up from VS itself. When running outside of VS the windows theme colours are used, so there can be differences between the two. Currently there isn’t a way to change that since the dialog itself is not public (just the wrapper that launches the dialog). So don’t be surprised if the Team Project Picker looks different then expected :-]

• Is using SVN for development and CM a bad practice?

  - by GatorGuy

  I have a bit of experience with SVN as a pure programmer/developer. Within my company, however, we use SVN as our configuration management tool. I thought using SVN for development at the same time was OK since we could use branches and the trunk for dev, and tags for releases. To me, the tags were the CM part, and the branches/trunk were the dev part. Recently a person, who develops high level code (but outside of the "pure SW" group) mentioned that the existing philosophy (mixing SVN for dev and CM) was wrong... in his opinion. His reasoning is that he thinks the company's CM tool should always link to run-able SW (so branches would break this rule). He also mentioned that a CM tool shouldn't be a backup utility for daily or incremental commits. Finally, he doesn't like the idea of having to jump from revision 143 to 89 in order to get a working copy... and further that CM tools shouldn't allow reversion to a broken state. In general he wants to separate the CM and back-up/dev utilties that SVN offers. Honestly, I am new and the person with this perspective is one of seniority, experience, and success, so I want to field this dilemma with the stackoverflow userbase to see if his approach has merit. My question: Should SVN be purely used for development, and another tool for CM (or vice versa)? Why? If so, what tools would you suggest for this combo? Or do you think that integrating both CM and dev into SVN is the best approach? Why? Thanks.

• CMS and Databases vs. DIY

  - by hozza

  I have been programming for many years now, primarily in PHP and the like and would consider myself an intermediate programmer. Some of my online projects have now gone global and very widely used, i am now in deep thought about scalability etc. All of my systems so far are written in PHP, no known database structure such as MySQL etc. Instead our databases use an 'operating system style' method of storing information, files and folders if you will. We also do not use any outside/third-party software or CMS, so far this has work out extremely well. Most people, when they hear about the way we do things, criticize and say that is an idiotic idea but normally after seeing our systems in more dept are converted to our way of doing things. Is it really that bad to not use a standard databasing systems and only using the one (slightly heavier than others) language of PHP? How well on the face of it will this kind of setup scale? N.B. Our systems include things such as account and user management, documentation development and task/project managing.

• Storing editable site content?

  - by hmp

  We have a Django-based website for which we wanted to make some of the content (text, and business logic such as pricing plans) easily editable in-house, and so we decided to store it outside the codebase. Usually the reason is one of the following: It's something that non-technical people want to edit. One example is copywriting for a website - the programmers prepare a template with text that defaults to "Lorem ipsum...", and the real content is inserted later to the database. It's something that we want to be able to change quickly, without the need to deploy new code (which we currently do twice a week). An example would be features currently available to the customers at different tiers of pricing. Instead of hardcoding these, we read them from database. The described solution is flexible but there are some reasons why I don't like it. Because the content has to be read from the database, there is a performance overhead. We mitigate that by using a caching scheme, but this also adds some complexity to the system. Developers who run the code locally see the system in a significantly different state compared to how it runs on production. Automated tests also exercise the system in a different state. Situations like testing new features on a staging server also get trickier - if the staging server doesn't have a recent copy of the database, it can be unexpectedly different from production. We could mitigate that by committing the new state to the repository occasionally (e.g. by adding data migrations), but it seems like a wrong approach. Is it? Any ideas how best to solve these problems? Is there a better approach for handling the content that I'm overlooking?

• Do I expect too much work from an employer? [closed]

  - by Ant

  I recently switched jobs because I was not challenged enough, the work would come in waves, and I HATED the people I worked with. I am a recent college grad, May 2009, and based off the 3 internships I had, and 2 full time jobs I obtained, I am finding that employers can not keep me satisfied with the amount of work. At my new job, I like the people I work with, I am challenged, but I still do not get enough work. I hate down time. I always want to have something to work on AT LEAST 6 out of the 8 hours. I was surprised that my new employer actually hired me because the majority of the technologies they implement, I had minimal exposure to. I never programmed in the technologies they use outside of one class in college. My greatest strength is that I am an extremely fast learner. I can pick up new technologies with relative ease. They gave me a project to work on by myself and I think they assumed it would take me longer to complete. Now that I finished that app, they are struggling to find something for me to do. I am not sure if it is bad timing being close to the holidays, my manager dealing with personal issues at home, how quickly I finished the first project, or that I expect too much out of an employer? If so, what are good things to do on all this downtime?! EDIT: Thanks for all the feedback! EDIT 2: I am going to "unaccept" the answer in an effort to keep the question open. As a few people have mentioned, this is a great discussion on how to grow as a new worker in the programming field. EDIT 3: I am attempting to revive this question so the moderators will see the support to re-open it.

• Did C++11 address concerns passing std lib objects between dynamic/shared library boundaries? (ie dlls and so)?

  - by Doug T.

  One of my major complaints about C++ is how hard in practice it is to pass std library objects outside of dynamic library (ie dll/so) boundaries. The std library is often header-only. Which is great for doing some awesome optimizations. However, for dll's, they are often built with different compiler settings that may impact the internal structure/code of a std library containers. For example, in MSVC one dll may build with iterator debugging on while another builds with it off. These two dlls may run into issues passing std containers around. If I expose std::string in my interface, I can't guarantee the code the client is using for std::string is an exact match of my library's std::string. This leads to hard to debug problems, headaches, etc. You either rigidly control the compiler settings in your organization to prevent these issues or you use a simpler C interface that won't have these problems. Or specify to your clients the expected compiler settings they should use (which sucks if another library specifies other compiler settings). My question is whether or not C++11 tried to do anything to solve these issues?

• A key principle of Scrum...

  - by AndyScott

  "A key principle of Scrum is its recognition that during a project the customers can change their minds about what they want and need (often called requirements churn), and that unpredicted challenges cannot be easily addressed in a traditional predictive or planned manner. As such, Scrum adopts an empirical approach—accepting that the problem cannot be fully understood or defined, focusing instead on maximizing the team’s ability to deliver quickly and respond to emerging requirements." I have been working in a SCRUM environment, with 4-6 week cycles, for about 6 months now and have been very pleased with the impact that it has had on my life (regular work hours, seeing my family, etc).  But was looking up the criteria for a 'Certified Scrum Master' and came across the SCRUM definition on Wikipedia, and started reading the actual definition.  My first thought was "hey, this development methodology actually allows you to deal with what happens in the real world (i.e. customers changing requirements); but is this "selling out" on solid requirements? I understand that this works in the environment that I am currently working in, where there are deep pockets paying the bills, and also making the descisions on what requirements to change / impliment; but is this a recepie for success in smaller or simply more budget concious environments?  Having the ability to be completely flexible when the client wants the product changed.   The more I think about it, the more I feel that SCRUM development may be better suited for an environment where a team is taking over a project from another team (bringing some outside development in-house or something of that ilk), as opposed to ground up development. What do you think?

• It is inconsiderate to place editor settings inside code files?

  - by Carlos Campderrós

  I know this is kind of a subjective question, but I'm curious if there's any good reason to place (or not place) editor settings inside code files. I'm thinking in vi modelines, but it is possible that this applies to other editors. In short, a vi modeline is a line inside a file that tells vi how to behave (indent with spaces or tabs, set tabwidth to X, autoindent by default or not, ...) that is placed inside a comment, so it won't affect the program/compiler when running. In a .c file it could be similar to // vim: noai:ts=4:sw=4 On one hand, I think this shouldn't be inside the file, as it is an editor setting and so belongs to an editor configuration file or property. On the other hand, for projects involving developers outside one company (that are not imposed an editor/settings) or collaborators on github/bitbucket/... it is an easy way to avoid breaking the code style (tabs vs spaces for example), but only for the ones that use that editor though. I cannot see any powerful enough reason to decide for or against this practice, so I am in doubt of what to do.

• How to define implementation details?

  - by woni

  In our project, an assembly combines logic for the IoC-Container, the project internals and the communication layer. The current version evolved to have only internal classes in addin assemblies. My main problem with this approach is, that the entry point is only available over the IoC-Container. It is not possible to use anything else than reflection to initialize the assembly. Everything behind the IoC-Interface is defined as implementation detail and therefore not intended for usages outside. It is well known that you should not test implementation detail (such as private and internal methods), because they should be tested through the public interface. It is also well known, that your tests should not use the IoC-Container to setup the SUTs, because that would result in too much dependencies. So we are using the InternalsVisibleTo-Attribute to make internals visible to our test assemblies and test the so called implementation details. I recognized that one problem could be the mixup between different concerns in that assembly, changing this would make this discussion useless, because classes have to be defined public. Ignoring my concerns with this, isn't the need to test a class enough reason to make it public, the usages of InternalsVisibleTo seems unintended, and a little bit "hacky". The approach to test only against the publicly available IoC-Container is too costly and would result in integration style tests. The pros of using internals are, that the usages are well known and do not have to be implemented like a public method would have to be (documentation, completeness, versioning,...). Is there a solution, to not test against internals, but keep their advantages over public classes, or do we have to redefine what an implementation detail is.
