• Touchpad stopped working on an Acer AspireOne D255E

  - by Gustavo

  I have a less than a year old Acer AspireOne D255E with a fresh install of Ubuntu 11.10. Everything has been working fine. Great OS and great netbook. But today the touchpad stopped working. It had been working fine. I closed the netbook and when I opened it again, a couple of hours later, I could not move the pointer with the touchpad. I can not get the pointer to move. I cleaned the touchpad surface well, just in case. Everything else is working fine. All the software updates are up-to-date. I have rebooted several times with no solution. I have attached an USB mouse and the pointer works well. What can I do to troubleshoot the problem? I have gone to the System Settings, touchpad section, and there is not much that I can do there. I would like to determine first if it is a hardware or software issue and then how to resolve it. Is there a way that I can reinstall the touchpad drivers. just in case it is a software problem? I have been using Ubuntu for nearly a year now and am very happy with it. Are there any wise Ubuntu gurus out there who can help me? Thank you for reading this note.

• Too many heap subpools might break the upgrade

  - by Mike Dietrich

  Recently one of our new upcoming Oracle Database 11.2 reference customers did upgrade their production database - a huge EBS system - from Oracle 9.2.0.8 to Oracle Database 11.2.0.2. They've tested very well, we've optimized the upgrade process, the recompilation timings etc.  But once the live upgrade was done it did fail in the JAVA component piece with this error: begin if initjvmaux.startstep('CREATE_JAVA_SYSTEM') then * ORA-29553: classw in use: SYS.javax/mail/folder ORA-06512: at "SYS.INITJVMAUX", line 23 ORA-06512: at line 5 Support diagnosis was pretty quick - and refered to:Bug 10165223 - ORA-29553: class in use: sys.javax/mail/folder during database upgrade But how could this happen? Actually I don't know as we have used the same init.ora setup on test and production. The only difference: the prod system has more CPUs and RAM. Anyway, the bug names as workarounds to either decrease the SGA to less than 1GB or decrease the number of heap subpools to 1. Finally this query did help to diagnose the number of heap subpools: select count(distinct kghluidx) num_subpools from x$kghlu where kghlushrpool = 1; The result was 2 - so we did run the upgrade now with this parameter set: _kghdsidx_count=1 And finally it did work well. One sad thing:After the upgrade did fail Support did recommend to restore the whole database - which took an additional 3-4 hours. As the ORACLE SERVER component has been already upgraded successfully at the stage where the error did happen it would have been fine to go on with the manual upgrade and start catupgrd.sql script. It would have been detected that the ORACLE SERVER is upgraded already and just picked up the non-upgraded components. The good news:Finally I had one extra slide to add to our workshop presentation

• Troubleshooting VMware on Ubuntu

  Summary of different problems while using VMware products on Ubuntu. This article is going to be updated from time to time with new information about running VMware products more or less smoothly on Ubuntu. Following are links to existing articles: Running VMware Player on Linux (xubuntu Hardy Heron) Running VMware Server on Linux (version 1.0.6 on xubuntu) Using ext4 in VMware machine   VMware mouse grab/ungrab problem (Source: LinuxInsight) Upgrading GTK library in Ubuntu since Karmic Koala gives you a strange mouse behaviour. Even if you have "Grab when cursor enters window" option set, VMware won't grab your pointer when you move mouse into the VMware window. Also, if you use Ctrl-G to capture the pointer, VMware window will release it as soon as you move mouse around a little bit. Quite annoying behavior... Fortunately, there's a simple workaround that can fix things until VMware resolves incompatibilities with the new GTK library. VMware Workstation ships with many standard libraries including libgtk, so the only thing you need to do is to force it to use it's own versions. The simplest way to do that is to add the following line to the end of the /etc/vmware/bootstrap configuration file and restart the Workstation. export VMWARE_USE_SHIPPED_GTK="force" The interface will look slightly odd, because older version of GTK is being used, but at least it will work properly. Note: After upgrading a new Linux kernel, it is necessary to compile the VMware modules, this requires to temporarily comment the export line in /etc/vmware/bootstrap.

• How can rotating release managers improve a project's velocity and stability?

  - by Yannis Rizos

  The Wikipedia article on Parrot VM includes this unreferenced claim: Core committers take turns producing releases in a revolving schedule, where no single committer is responsible for multiple releases in a row. This practice has improved the project's velocity and stability. Parrot's Release Manager role documentation doesn't offer any further insight into the process, and I couldn't find any reference for the claim. My first thoughts were that rotating release managers seems like a good idea, sharing the responsibility between as many people as possible, and having a certain degree of polyphony in releases. Is it, though? Rotating release managers has been proposed for Launchpad, and there were some interesting counterarguments: Release management is something that requires a good understanding of all parts of the code and the authority to make calls under pressure if issues come up during the release itself The less change we can have to the release process the better from an operational perspective Don't really want an engineer to have to learn all this stuff on the job as well as have other things to take care of (regular development responsibilities) Any change of timezones of the releases would need to be approved with the SAs and: I think this would be a great idea (mainly because of my lust for power), but I also think that there should be some way making sure that a release manager doesn't get overwhelmed if something disastrous happens during release week, maybe by have a deputy release manager at the same time (maybe just falling back to Francis or Kiko would be sufficient). The practice doesn't appear to be very common, and the counterarguments seem reasonalbe and convincing. I'm quite confused on how it would improve a project's velocity and stability, is there something I'm missing, or is this just a bad edit on the Wikipedia article? Worth noting that the top voted answer in the related "Is rotating the lead developer a good or bad idea?" question boldly notes: Don't rotate.

• Scaling Sound Effects and Physics with Framerate

  - by Thomas Bradsworth

  (I'm using XNA and C#) Currently, my game (a shooter) runs flawlessly with 60 FPS (which I developed around). However, if the framerate is changed, there are two major problems: Gunshot sound effects are slower Jumping gets messed up Here's how I play gunshot sounds: update(gametime) { if(leftMouseButton.down) { enqueueBulletForSend(); playGunShot(); } } Now, obviously, the frequency of playGunShot depends on the framerate. I can easily fix the issue if the FPS is higher than 60 FPS by capping the shooting rate of the gun, but what if the FPS is less than 60? At first I thought to just loop and play more gunshots per frame, but I found that this can cause audio clipping or make the bullets fire in "clumps." Now for the second issue: Here's how jumping works in my game: if(jumpKey.Down && canJump) { velocity.Y += 0.224f; } // ... (other code) ... if(!onGround) velocity.Y += GRAVITY_ACCELERATION * elapsedSeconds; position += velocity; The issue here is that at < 60 FPS, the "intermediate" velocity is lost and therefore the character jumps lower. At 60 FPS, the game adds more "intermediate" velocities, and therefore the character jumps higher. For example, at 60 FPS, the following occurs: Velocity increased to 0.224 Not on ground, so velocity decreased by X Position increased by (0.224 - X) <-- this is the "intermediate" velocity At 30 FPS, the following occurs: Velocity increased to 0.224 Not on ground, so velocity decreased by 2X Position increased by (0.224 - 2X) <-- the "intermediate" velocity was lost All help is appreciated!

• CA For A Large Intranet

  - by Tim Post

  I'm managing what has become a very large intranet (over 100 different hosts / services) and will be stepping down from my role in the near future. I want to make things easy for the next victim person who takes my place. All hosts are secured via SSL. This includes various portals, wikis, data entry systems, HR systems and other sensitive things. We're using self signed certificates which worked o.k. in the past, but are now problematic because: Browsers make it harder for users to understand exactly what is going on when a self signed certificate is encountered, much less accept them. Putting up a new host means 100 phone calls asking what "Add an exception" means What we were doing is just importing the self signed certs when we set up a new workstation. This was fine when we only had a dozen to deal with, but now its just overwhelming. Our I.T. Department has classified this as ya all's problem, all we get from them is support for switch and router configurations. Beyond the user having connectivity, everything else is up to the intranet administrators. We have a mix of Ubuntu and Windows workstations. We'd like to set up our own self signed CA root, which can sign certificates for each host that we deploy on the intranet. Client browsers would of course be told to trust our CA. My question is, would this be dangerous and would we be better off going with intermediate certificates from someone like Verisign? Either way, I still have to import the root for the intermediate CA, so I really don't see what the difference is? Other than charging us money, what would Verisign be doing that we could not, beyond protecting the root CA cert so it can't be used to make forgeries?

• Composing programs from small simple pieces: OOP vs Functional Programming

  - by Jay Godse

  I started programming when imperative programming languages such as C were virtually the only game in town for paid gigs. I'm not a computer scientist by training so I was only exposed to Assembler and Pascal in school, and not Lisp or Prolog. Over the 1990s, Object-Oriented Programming (OOP) became more popular because one of the marketing memes for OOP was that complex programs could be composed of loosely coupled but well-defined, well-tested, cohesive, and reusable classes and objects. And in many cases that is quite true. Once I learned object-oriented programming my C programs became better because I structured them more like classes and objects. In the last few years (2008-2014) I have programmed in Ruby, an OOP language. However, Ruby has many functional programming (FP) features such as lambdas and procs, which enable a different style of programming using recursion, currying, lazy evaluation and the like. (Through ignorance I am at a loss to explain why these techniques are so great). Very recently, I have written code to use methods from the Ruby Enumerable library, such as map(), reduce(), and select(). Apparently this is a functional style of programming. I have found that using these methods significantly reduce code volume, and make my code easier to debug. Upon reading more about FP, one of the marketing claims made by advocates is that FP enables developers to compose programs out of small well-defined, well-tested, and reusable functions, which leads to less buggy code, and low code volume. QUESTIONS: Is the composition of complex program by using FP techniques contradictory to or complementary to composition of a complex program by using OOP techniques? In which situations is OOP more effective, and when is FP more effective? Is it possible to use both techniques in the same complex program? Do the techniques overlap or contradict each other?

• How does a game developer get feedback from gamers (not developers) or start a forum community without paying for advertising or hiring Q&A teams?

  - by Carter81

  I am familiar with a lot of game developer forums, but I'd assume this is much less likely to attract more casual commentators. I also fear that feedback from a gamer's perspective would often be tainted by their game dev perspective. For example, if I were making a RTS game and wanted to get feedback from "The RTS gamers" where would I go? Is there a general idea of what type of website or forum to go to? Do you go to specific game websites, to try to "steal" attention? Would this not equate to spam or inappropriate posting? What is considered appropriate and inappropriate? I am not asking for specifics. I am asking how one "starts a community", or how one "gets feedback from gamers" without resorting to spamming forums or 'advertising' just to see what sticks. What TYPE OF PLACE does one go? Are there already sites designed for this purpose? I tried going to what was once a very popular forum for feedback from what I believed was a niche hardcore group of gamers in the genre, but its popularity seemed to have died significantly; Leaving only trolls and very young teenagers. The resulting feedback was quite disappointing, mainly for how little feedback it resulted. Many years ago, feedback would flood in by the hundreds so quickly. Without this website, I am at a loss as to where to go to see what people think of ideas, gather feedback from a gamer's perspective (not a developer's perspective), or where to pull from to start my own site's forum. I am out of ideas of what to do, short of going to various game forums to post in the off-topic sections there.

• Clean MVC design when there is viewer latency

  - by Tony Suffolk 66

  It isn't clear if this question has already been answered, so apologies in advance if this is a duplicate : I am implementing a game and trying to design around a clean MVC pattern - so my Control plane will implement the rules of the game (but not how the game is displayed), and the View plane implements how the game is displayed, and user iteraction - i.e. what game items or controls the user has activated. The challenge that I have is this : In my game the Control Plane can move game items more or less instaneously (The decision about what item to place where - and some of the initial consequences of that placement are reasonably trivial to calculate), but I want to design the Control Plane so that the View plane can display these movements either instaneously or using movement animations. The other complication is that player interaction must be locked out while those game items are moving (similar to chess - you can't attack an opposing piece as it moves past one of your pieces) So do I : Implement all the logic in the Control Plane asynchronously - and separate the descision making from the actions - so the Control plane decides piece 'A' needs to move to a given place - tells the view plane, and but does not implement the move in data until the view plane informs the control plane that the move/animation is complete. A lot of interlock points between the two layers. Implement all the control plane logic in one place - decisions and movement (keeping track of what moved where), and pass all the movements in one go to the View plane to do with what it will. Control Plane is almost fire and forget here. A hybrid of 1 & 2 - The control plane implements all the moves in a temporary data store - but maintains a second store which reflects what is actually visible to the viewer, based on calls and feedback from the View plane. All 3 are relatively easy to implement (target language is python), but having never done a clean MVC pattern with view latency before - I am not sure which design is best

• Social-network, online community, company and job reviews, salaries statistics and much more.. Do we have it? Do we need it?

  - by Vlad Lazarenko

  I have many friends from Ukraine who are programmers. So I found out that they have a web site that collects, organizes and analyzing information about IT companies, which includes location, feedbacks, company reviews from current and former employees etc. They also collect programming salaries and organize them by language, region etc. That web site is ran by programmers and for programmers, all information is absolutely public and free. Plus, web site has forums, and people can discuss (more or less social than specific programming stuff) things, publish articles, news etc. I personally think that is useful, especially for those who are new in this industry. For example, you may do a small research and find out that, for example, Java programmers getting paid more than PHP programmers but demand is lower. Or you get an offer from the company, is about to accept it, but read reviews and find out that they don't even provide internet access at work and if you need to download something, you have to ask your manager to do it for you, and managers share a single computer that has internet connection to get that stuff for you (there is only one such company in Kiev, Ukraine, called SMK, for Software Mac Kiev, a big shame). So the question is - do we have something like it in US? Or at least, say, for New York region? Or state? All information I managed to find online is inaccurate or not full. Forums are very specific. If we don't have it, would you be interested in creating such a portal? Thanks!

• Why do memory-managed languages retain the `new` keyword?

  - by Channel72

  The new keyword in languages like Java, Javascript, and C# creates a new instance of a class. This syntax seems to have been inherited from C++, where new is used specifically to allocate a new instance of a class on the heap, and return a pointer to the new instance. In C++, this is not the only way to construct an object. You can also construct an object on the stack, without using new - and in fact, this way of constructing objects is much more common in C++. So, coming from a C++ background, the new keyword in languages like Java, Javascript, and C# seemed natural and obvious to me. Then I started to learn Python, which doesn't have the new keyword. In Python, an instance is constructed simply by calling the constructor, like: f = Foo() At first, this seemed a bit off to me, until it occurred to me that there's no reason for Python to have new, because everything is an object so there's no need to disambiguate between various constructor syntaxes. But then I thought - what's really the point of new in Java? Why should we say Object o = new Object();? Why not just Object o = Object();? In C++ there's definitely a need for new, since we need to distinguish between allocating on the heap and allocating on the stack, but in Java all objects are constructed on the heap, so why even have the new keyword? The same question could be asked for Javascript. In C#, which I'm much less familiar with, I think new may have some purpose in terms of distinguishing between object types and value types, but I'm not sure. Regardless, it seems to me that many languages which came after C++ simply "inherited" the new keyword - without really needing it. It's almost like a vestigial keyword. We don't seem to need it for any reason, and yet it's there. Question: Am I correct about this? Or is there some compelling reason that new needs to be in C++-inspired memory-managed languages like Java, Javascript and C#?

• Sorting objects before rendering

  - by dreta

  I'm trying to implement a scene graph and in all the articles i've come across there is talk about object sorting. So you'd sort your objects by "material" for example. Now untill i sat down and started implementing it, i kind of took this for granted, because it made sense. But now i'm wondering what does sorting actually change? In my engine, i have a manager for UBOs, i use those to store data that'll be shared between programs, at the moment that only involves time, camera and projection matrices and lights (i'm not worrying about managing which lights affect which objects ATM). Now for each model i have to change the model to world matrix uniform, no sorting is going to change that. So is the jump from changing this matrix to also setting a material for each object that bad? I vaguely remember reading somewhere that each time you change something in the pipeline, it has to get flushed and that can cause performance issues. But for each drawing call i'm setting up a model to world matrix anyway, so what sense does it make to ever be concerned about this? BTW is there any information about whether changing a uniform and calling glBufferSubData is more (or less) expensive.

• Why the clip space in OpenGL has 4 dimensions?

  - by user827992

  I will use this as a generic reference, but the more i browser online docs and books, the less i understand about this. const float vertexPositions[] = { 0.75f, 0.75f, 0.0f, 1.0f, 0.75f, -0.75f, 0.0f, 1.0f, -0.75f, -0.75f, 0.0f, 1.0f, }; in this online book there is an example about how to draw the first and classic hello world for OpenGL about making a triangle. The vertex structure for the triangle is declared as stated in the code above. The book, as all the other sources about this, stress the point that the Clip Space is a 4D structure that is used to basically decide what will be rasterized and rendered to the screen. Here I have my questions: i can't imagine something in 4D, i don't think that a human can do that, what is a 4D for this Clip space ? the most human-readable doc that i have read speaks about a camera, which is just an abstraction over the clipping concept, and i get that, the problem is, why not using the concept of a camera in the first place which is a more familiar 3D structure? The only problem with the concept of a camera is that you need to define the prospective in other way and so you basically have to add another statement about what kind of camera you wish to have. How i'm supposed to read this 0.75f, 0.75f, 0.0f, 1.0f ? All i get is that they are all float values and i get the meaning of the first 3 values, what does it mean the last one?

• June 2012 Critical Patch Update for Java SE Released

  - by Eric P. Maurice

  Hi, this is Eric Maurice. Oracle just released the June 2012 Critical Patch Update for Java SE.  This Critical Patch Update provides 14 new security fixes across Java SE products.  As discussed in previous blog entries, Critical Patch Updates for Java SE will, for the foreseeable future, continue to be released on a separate schedule than that of other Oracle products due to previous commitments made to Java customers.  12 of the 14 Java SE vulnerabilities fixed in this Critical Patch Update may be remotely exploitable without authentication.  6 of these vulnerabilities have a CVSS Base Score of 10.0.  In accordance with Oracle’s policies, these CVSS 10 scores represent instances where a user running a Java applet or Java Web Start application has administrator privileges (as is typical on Windows XP).  When the user does not run with administrator privileges (typical on the Solaris and Linux operating systems), the corresponding CVSS impact scores for Confidentiality, Integrity, and Availability for these vulnerabilities would be "Partial" instead of "Complete", thus lowering these CVSS Base Scores to 7.5. Due to the high severity of these vulnerabilities, Oracle recommends that customers obtain and apply these security fixes as soon as possible: Developers should download the latest release at http://www.oracle.com/technetwork/java/javase/downloads/index.html    Java users should download the latest release of JRE at http://java.com, and of course  Windows users can take advantage of the Java Automatic Update to get the latest release. In addition, Oracle recommends removing old an unused versions  of Java as the latest version is always the recommended version as it contains the most recent enhancements, and bug and security fixes.  For more information: •Instructions on removing older (and less secure) versions of Java can be found at http://java.com/en/download/faq/remove_olderversions.xml  •Users can verify that they’re running the most recent version of Java by visiting: http://java.com/en/download/installed.jsp   •The Advisory for the June 2012 Critical Patch Update for Java SE is located at http://www.oracle.com/technetwork/topics/security/javacpujun2012-1515912.html

• What are `Developmental Milestones` for programming skills?

  - by Holmes

  I studied in the field of Computer Science for 6 years, bachelor's degree and master's degree. I have studied all the basic programming like C, Java, VB, C#, Python, and etc. When I have free times, I will learn new programming languages and follow new programming trends by myself , such as PHP, HTML5, CSS5, LESS, Bootstrap, Symfony2, and GitHub. So, if someone wants me to write some instructions using these languages, I'm certain that I can do it, not so good but I can get a job done. However, I don't have any favorite programming language. Moreover, I also have studied about algorithms, database, and etc. Everything I just wrote so far seems that I know a lot in this field. In fact, I feel I am very stupid. I cannot answer 80% of the questions on SO. In spite of those languages??, I have studied. Perhaps it is because I have never worked before. As there is the Developmental Milestones for children, which refers to how a child becomes able to do more complex things as they get older, I would like to evaluate the same thing but for programming skills. What are the set of functional skills or age-specific tasks that most programmers can do at a certain age range? In order to evaluate myself, I would like to ask your opinions that all of the skills I mentioned above, are they enough for programmers to know when they are 25 years old? What are your suggestions in order to improve the skills in this field?

• Antenna Aligner Part 6: Little Robots

  - by Chris George

  A week ago I took temporary ownership of a HTC Desire S so that I could start testing my app under Android. Support for Android was not in my original plan, but when Nomad added support for it recently, I starting thinking why not! So with some trepidation, I clicked the Build for Android button on the Nomad toolbar... nothing. Hmm... that's not right, I was expecting something to build. After a bit of faffing around I finally realised that I hadn't read the text on the Android setup page properly (yes that's right, RTFM!), and I needed a two-part application identifier, separated by a dot. I did this (not sure what the two part thing is all about, that one my list to investigate!) After making the change, the Android build worked and created the apk file. I uploaded this to the device and nervously ran it... it worked!!!  Well, more or less! So, there was not splash screen, but this was no surprise because I only have the iOS icons and splash screen in my project at the moment. What was more concerning was the compass update didn't seem to be working. I suspect this is a result of using an iOS specific option in the Phonegap compass watcher. Another thing to investigate. I've also just noticed that the css gradient background hasn't worked either... These issues aside, it was actually more successful than I was expecting, so happy days! Right, lets get Googling...   Next time: Preparing for submission to the App Store! :-)

• Reaching Intermediate Programming Status

  - by George Stocker

  I am a software engineer that's had positions programming in VBA (though I dare not consider that 'real' experience, as it was trial and error!), Perl w/ CGI, C#, and ASP.NET. The latter two are post-undergraduate, with my entrance into the 'real world'. I'm 2 years out of college, and have had 5 years of experience (total) across the languages I've mentioned. However, when it comes to my resume, I can only put 2 years down for C#, and less than a year down for ASP.NET. I feel like I know C#, but I still have to spend time going 'What does this method do?', whereas some of the more senior level engineers can immediately say, "Oh, Method X does this, without ever having looked at that method before." So I know empirically that there's a gulf there, but I'm not exactly sure how to bridge it. I've started programming in Project Euler, and I picked up a book on design patterns, but I still feel like I spend each day treading water, instead of moving forward. That isn't to say that I don't feel like I've made progress, it just means that as far as I come each day, I still see the mountain top way off in the distance. My question is this: How did you overcome this plateau? How long did it take you? What methods can you suggest to assist me in this? I've read through Code Complete, The Mythical Man Month, and CLR via C#, 2nd edition -- my question is: What do I do now? Edit: I just found this question on projects for an intermediate level programmer. I think it adds to the discussion (though it does not supplant my question). As such, I'm adding it to the question as a "For More Information".

• c++ How to use angular velocity that derived from inertia and force(torque) in 3d

  - by user1217203

  I am relatively new to game development. May my terminology and description are not appropriate. Please excuse my poor phrasing and help me by giving advice on how to question better if this question seems less fitting. I really appreciate your efforts. Hi. I am having hard time interpreting the set of values I have. I have inertia and force(torque) in terms of x y z. FYI I used x and y coordinates as my ground, flat coordinates and z as my up/down. I am assuming that since f = ma, that angular acceleration must be a = f / m. So I divide my torque by inertia. Then I add those x y z values to my angular velocity variable's x y z. However these x y z values confuse me. Don't I need angle/sec or radian/sec sort of values in order to apply rotation? The x y z values I have seemed to not say anything about radians or angular movement. Question : If I have ( 1, 2, 3 ) or any ( x, y, z ) as my angular velocity, how do I actually apply it as angular movement? FYI Here I am pasting my code : float mass = 100; float devidedMass = 1.0/12 * mass; Vec3 innertia( devidedMass* (_box._size.z*_box._size.z + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.x*_box._size.x), devidedMass* (_box._size.y*_box._size.y + _box._size.z*_box._size.z )); box._angAccel += forceAng/innertia; box._angVelo += box._angAccel; box._angAccel.allZero(); source of my inertia calculation http://www.health.uottawa.ca/biomech/courses/apa4311/solids.pdf

• Interesting 3d zooming technique

  - by stark

  Is it possible to zoom to a certain point on screen by modifying the field of view and rotating the camera as to keep that point/object in the same place on screen while zooming ? Changing the camera position is not allowed.. I projected the 3d pos of the object on screen and remembered it. Then on each frame I calculate the direction to it in camera space and then I construct a rotation matrix to align this direction to Z axis (in cam space). After this, I calculate the direction from the camera to the object in world space and transform this vector with the matrix I obtained earlier and then use this final vector as the camera's new direction. And it's actually "kinda working", the problem is that it is more/less off than the camera's rotation before starting to zoom depending on the area you are trying to zoom in (larger error on edges/corners). It looks acceptable, but I'm not settling for only this. Any suggestions/resources for doing this technique perfectly ? If some of you want to explain the math in detail, be my guests, I can understand these things well. Thanks. Edit: I'll check often for responses, I'm really curious about this :D

• The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

  - by Hunter2

  Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

• Who should be the architect in an agile project?

  - by woni

  We are developing the agile way for a few months now and I have some troubles understanding the agile manifesto as interpreted by my colleagues. The project we are developing is a framework for future projects and will be reused many times in the next years. Code is only written to fulfill the needs of the current user story. The product owner tells us what to do, but not how to do it. What would be right, in my opinion, because he is not implicitly a programmer. The project advanced and in my eyes it messed up a little bit. After I recognized an assembly that was responsible for 3 concerns (IoC-Container, communication layer and project internal things), I tried to address this to my colleagues. They answered that this would be the result of applying YAGNI, because know one told them to respect that functionalities have to be split up in different assemblies for further use. In my opinion no one has to tell us that we should respect the Separation of Concerns principle. On the other side, they mentioned to prefer YAGNI over SoC because it is less effort to implement and therefore faster and cheaper. We had changing requirements a lot at the beginning of the project and ended up in endless refactoring sessions, because to much has to be adapted. Is it better to make such rather simple design decisions up front, even there is no need in the current situation, or do we have to change a lot in the later progress of the project?

• How do you keep your basic skills from atrophy?

  - by kojiro

  I've been programming for about 10 years, and I've started to migrate to more of a project management position. I still do coding, but less often now. One of the things that I think is holding me back in my career is that I can't "let go". I think I fear letting hard-won programming skills atrophy while I sit in meetings and annotate requirements. (Not to mention I don't trust people to write requirements who don't understand the code.) I can't just read books and magazines about coding. I'm involved in some open source projects in my free time, and stackoverflow and friends help a bit, because I get the opportunity to help people solve their programming problems without micromanaging, but neither of these are terribly structured, so it's tempting to work first on the problems I can solve easily. I guess what I'd like to find is a structured set of exercises (don't care what language or environment) that… …I can do periodically …has some kind of time requirement so I can tell if I've been goofing off …has some kind of scoring so I can tell if I'm making mistakes Is there such a thing? What would you do to keep your skills fresh?

• Maintaining a main project line with satellite projects

  - by NickLarsen

  Some projects I work on have a main line of features, but are customizable per customer. Up until now those customizations have been implemented as preferences, but now there are 2 problems with the system... The settings page is getting out of control with features. There are probably some improvements that could be made to the settings UI, but regardless, it is quite cumbersome setting up new instances for new customers. Customers have started asking for customizations which would be more easily maintained as separate threads instead of having tons of customizations code. Optimally I am envisioning some kind of source control in which features are either in the main project line and customizations per customer are maintained in a repo per customer set up. The customizations per project would need to remain separate but if a bug is found and fixed in a particular project, I would need to percolate the fix back to the main line and into all of the other customer repos. The problem is I have never seen this done before, and before spending time trying to find source control that can accommodate this scenario and implement it, I figure it best to ask if anyone has something less complicated or knows of a source control product which can handle this with very little hair pulling.
