• Introducing Deep Fried Devcast

  - by Matt Christian

  I've been working on a new podcast for the game development community called the Deep Fried Devcast.  Currently we are in pre-production but should have some episodes up in the near future.  Here is a quick FAQ about the show: What is the Deep Fried Devcast? The Deep Fried Devcast is a bi-weekly show all about game development.  The show will feature developer interviews, a focus on the technical aspects of game development (programming, technical design), the business of team game development (time management, project management), and other areas focused around the actual development of games. Wait, no game design?  No game discussions?! Calm down, calm down.  Although the focus of the podcast is on the technical aspects of game dev, there will be episodes and content focused on all areas of the gaming industry, including discussion on design, story, recent game releases, games we've been playing, etc...  Anything could show up in the Deep Fried Devcast and nothing is off limits. How can I help? We're always looking for new content ideas, emails, and anything you want to send us (within some kind of reason!).  You can even be a guest host if you want!  Email us at: deepfrieddevcast [AT] gmail [DOT] com Where's the podcast?! We're still recording it!  Don't worry, it will be up soon.  Keep an eye on www.deepfrieddevcast.com for the latest updates (that will be up soon too!).

• Game-a-Week One Completed

  - by Matt Christian

  Last night I finished my Game-a-Week One and felt and extreme sense of accomplishment with what I finished in a single week. I removed all traces of the JigLibX code since it wasn't working properly due to my implementation and got my collision working thanks to some BoundingSpheres and Riemer's tutorials.  However, since the characters are Corndogs a rectangle bounding box would have made more sense although the bullets are only able to move forward currently. While developing it in a week was a challenge, developing it in a week while maintaining proper coding standards and clean, reusable code was damn near impossible.  It's possible my next step will be to either refactor it or move onto Game-a-Week Two. I will post a link to the game ZIP in the future.

• Lightweight, dynamic, fully JavaScript web UI library recommendations

  - by Matt Greer

  I am looking for recommendations for a lightweight, dynamic, fully JavaScript UI library for websites. Doesn't have to be amazing visually, the end result is for simple demos I create. What I want can be summed up as "Ext-like, but not GPL'ed, and a much smaller footprint". I want to be able to construct UIs dynamically and fully through code. My need for this is currently driven by this particle designer. Depending on what query parameters you give it, the UI components change, example 1, example2. Currently this is written in Ext, but Ext's license and footprint are turn offs for me. I like UKI a lot, but it's not very good for dynamically building UIs since everything is absolutely positioned. Extending Uki to support that is something I am considering. Ideally the library would let me make UIs with a pattern along the lines of: var container = new SomeUI.Container(); container.add(new SomeUI.Label('Color Components')); container.add(new SomeUI.NumberField('R')); container.add(new SomeUI.NumberField('G')); container.add(new SomeUI.NumberField('B')); container.add(new SomeUI.CheckBox('Enable Alpha')); container.renderTo(someDiv);

• Game-a-Week One

  - by Matt Christian

  Anyone who chats with me on a semi-regular basis knows I am absolutely horrible at completing something from beginnning to end.  Often times I'll begin something, lose interest at some point, and end up moving onto the next thing.  For example, I have 1/2 a full game created, 1/3 of a novel written, and half of a model set created.  Needless to say, unless I have some sort of pressure to finish something I don't stick to it. Recently however one of my online buddies challenged me to create a simple game.  The start date was last Thursday and the final game needed to be delivered by this next Sunday (giving me just over a week).  However, I am going out of town this Friday so will need to deliver it by Thursday, giving me exactly 1 week to develop a game.  Here is what the game needed to include: The player should be able to shoot Shooting things should score points Sounds very simple, but given a single week to produce all art assets plus the game isn't an easy task.  So far I've developed: An animated Main Menu that loads via script files, allows the user to start a new game or exit the game The game is 3D and the player can move around the play area with an 'over-the-shoulder' camera HUD elements are drawn to display the player's current score When the player presses Esc they are shown a pause menu where they can resume the game by pressing Esc again, or quit the game by pressing Space There are also 2 items implemented that don't work perfectly: JigLibX physics library implementation On the main menu there is an arrow symbol that rotates to always point at your mouse I've got 2 days of development left so hopefully I can get collision working, some of the art cleaned up, and some more of the camera functionality working.  Also, I'll need to take some time to package the game up which hopefully shouldn't take too long.

• How do I deploy a charm from a local repository?

  - by Matt McClean

  I am trying to run the Charm tutorial from the juju documentation by creating a new charm from a local repository. I started by installing the charms from bzr to my local ubuntu 12.04 desktop running in a virtual machine. The new file structure is the following: ubuntu@ubuntu-VirtualBox:~$ find charms/precise/drupal/ charms/precise/drupal/ charms/precise/drupal/hooks charms/precise/drupal/hooks/db-relation-changed charms/precise/drupal/hooks/install charms/precise/drupal/hooks/start charms/precise/drupal/hooks/stop charms/precise/drupal/metadata.yml charms/precise/drupal/README When I install the mysql charm, which was downloaded from the remote charm repository, it works fine. However when I run the following command to deploy the new charm it fails with the following error message: ubuntu@ubuntu-VirtualBox:~$ juju deploy --repository=charms local:precise/drupal 2012-05-09 10:01:05,671 INFO Searching for charm local:precise/drupal in local charm repository: /home/ubuntu/charms 2012-05-09 10:01:05,845 WARNING Charm '.mrconfig' has an error: CharmError() Error processing '/home/ubuntu/charms/precise/.mrconfig': unable to process /home/ubuntu/charms/precise/.mrconfig into a charm Charm 'local:precise/drupal' not found in repository /home/ubuntu/charms 2012-05-09 10:01:06,217 ERROR Charm 'local:precise/drupal' not found in repository /home/ubuntu/charms Is there some file missing in the drupal charm directory that juju needs to make the charm valid? Also, I get the file processing error for the .mrconfig file also when deploying the mysql charm so is there something I need to change there perhaps?

• Language parsing to find important words

  - by Matt Huggins

  I'm looking for some input and theory on how to approach a lexical topic. Let's say I have a collection of strings, which may just be one sentence or potentially multiple sentences. I'd like to parse these strings to and rip out the most important words, perhaps with a score that denotes how likely the word is to be important. Let's look at a few examples of what I mean. Example #1: "I really want a Keurig, but I can't afford one!" This is a very basic example, just one sentence. As a human, I can easily see that "Keurig" is the most important word here. Also, "afford" is relatively important, though it's clearly not the primary point of the sentence. The word "I" appears twice, but it is not important at all since it doesn't really tell us any information. I might expect to see a hash of word/scores something like this: "Keurig" => 0.9 "afford" => 0.4 "want" => 0.2 "really" => 0.1 etc... Example #2: "Just had one of the best swimming practices of my life. Hopefully I can maintain my times come the competition. If only I had remembered to take of my non-waterproof watch." This example has multiple sentences, so there will be more important words throughout. Without repeating the point exercise from example #1, I would probably expect to see two or three really important words come out of this: "swimming" (or "swimming practice"), "competition", & "watch" (or "waterproof watch" or "non-waterproof watch" depending on how the hyphen is handled). Given a couple examples like this, how would you go about doing something similar? Are there any existing (open source) libraries or algorithms in programming that already do this?

• What can I do about Hack Attempts

  - by Matt

  I have an ASP.net website hosted using the Ultidev Web Server Pro. Every day I get a steady stream of errors generated by my application where page requests were requested and denied. This is obviously someone/something trying to find any exploits on my website.

• Development teams do not scale

  - by Matt Watson

  Recently I have been thinking about how development teams don't scale very well. The bigger a team and the product get, the more time the team spends fixing software bugs. This means they spend more time doing troubleshooting and debugging as the grow. The problem is that since developers don't typically have access to production servers, there is a bottleneck in the process when doing production troubleshooting.For a team that has 10 developers, I would guess than 0-2 of them have access to production servers. If that team grows to 20 people, it is probably the same 0-2 people that have production access still. This means that those 2 key people are a bottleneck and the team does not scale correctly as you add more resources. All those new developers want is to help track down and fix software bugs, but they don't have the visibility to do it. So they end up being less productive and frustrated because they really want to fix the problems. The people who do have production access end up spending too much of their time doing troubleshooting instead of working on new projects.The solution is to remove the bottlenecks and get those people working on more important tasks. Stackify can solve this problem by giving all the developers read only access to production servers. This allows them to access the information they need to do troubleshooting on their own.

• Game-a-Week 2 (The Sequel)

  - by Matt Christian

  After finishing Game-a-Week One I immediately wanted to go back and begin refactoring the code although I also wanted to work on a game demo idea I've had for quite awhile.  I tried doing both over the holiday weekend while up north (without internet!) and eventually hit a wall with an error. Today I am going to restart my refactoring and updates by starting Game-a-Week 2.  This challenge is to do the following: Refactor the old code Add a handful of new features to the demo This sounds simple enough but will be quite a challenge to finish in just around a week.  I have an idea on how I want to refactor the code, but the new features I'd like to implement will be tricky.  I'm going to try to implement: Quest giving / finishing / NPC's Quest Log Menu Inventory giving / receiving Inventory Menu This Game-a-Week is much more design oriented although will provide a good challenge for programming as well.  Wish me luck!

• HDMI audio output problems with Radeon card

  - by Matt Robinson

  No matter how much advice I follow, I still cannot get any audio to come out through my HDMI connection. I've tried downloading the latest proprietary FGLRX graphics drivers, and I've also gone into /etc/default/grub and altered GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" into this GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" But still I cannot get any sound nor can I get HDMI sound output to show up in Sound Settings or Pulse Audio Volume Control. I can get video to show up just fine on my monitor through HDMI so I'm sure this problem is fixable! I know this is an old problem with Ubuntu, but any new strategies into the problem would be much appreciated. With that being said, here are some of my specs: Ubuntu 12.04 LTS AMD Radeon HD 7520G

• Run Python Server at Startup

  - by DizzyDoo

  Hello, I've got a few Python based servers that I need to run, and would like them to start automatically when I start my Ubuntu Server box. What is the best way to execute them like this? I was hoping I could write a Bash script and use Screen to get them running in the background, where I can check on them every now and then, but where as echo screen -d -m python works just fine, echo screen -d -m `sudo python /home/matt/tornadoServer/tornadoDeploy.py` doesn't, with no error messages. Is that something to do with the spaces? Even though I did surround it with backquotes? I also tried: WEB="screen -d -m `sudo python /home/matt/tornadoServer/tornadoDeploy.py`" echo $WEB As a way of escaping the spaces, but no luck. What's Bash scripting way to do this? And, once the Bash script works, where can I put it to make it execute on startup?

• We're Subversion Geeks and we want to know the benefits of Mercurial

  - by Matt

  Having read I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS. I have a related follow up question. I read that question and read the recommended links and videos and I see the benefits but I don't see the overall mindshift people are talking about. Our team is of 8-10 developers that work on one large code base consisting of 60 projects. We use Subversion and have a main trunk. When a developer starts a new Fogbugz case they create a svn branch, do the work on the branch and when they're done they merge back to the trunk. Occasionally they may stay on the branch for an extended time and merge the trunk to the branch to pick up the changes. When I watched Linus talk about people creating a branch and never doing it again, that's not us at all. We create probably 50-100 branches a week without issue. The biggest challenge is the merging but we've gotten pretty good at that as well. I tend to merge by fogbugz case & checkin rather than the entire root of the branch. We never work remotely and we never make branches off of branches. If you're the only one working in that section of the code base then the merge to the trunk goes smoothly. If someone else had modified the same section of code then the merge can get messy and you might need to do some surgery. Conflicts are conflicts, I don't see how any system could get it right most of the time unless if was smart enough to understand the code. After creating a branch the following checkout of 60k+ files takes some time but that would be an issue with any source control system we'd use. Is there some benefit of any DVCS that we're not seeing that would be of great help to us?

• Are nullable types preferable to magic numbers?

  - by Matt H

  I have been having a little bit of a debate with a coworker lately. We are specifically using C#, but this could apply to any language with nullable types. Say for example you have a value that represents a maximum. However, this maximum value is optional. I argue that a nullable number would be preferable. My coworker favors the use of zero, citing precedent. Granted, things like network sockets have often used zero to represent an unlimited timeout. If I were to write code dealing with sockets today, I would personally use a nullable value, since I feel it would better represent the fact that there is NO timeout. Which representation is better? Both require a condition checking for the value meaning "none", but I believe that a nullable type conveys the intent a little bit better.

• How do you install a USB CD Rom drive in Ubuntu 10.04?

• Can't understand example using continuations

  I'm reading the r6rs Scheme report and am confused by the explanation of continuations (I find it to be too dense and lacking of examples for a beginner). What is this code doing and how does it evaluate to 4? Why does call/cc want an argument that's a function of one argument? How is call/cc's argument used? (+ 1 (call-with-current-continuation (lambda (escape) (+ 2 (escape 3))))) =? 4 This example is from section 1.11 - Continuations.

• Isolating test data in acceptance tests

  - by Matt Phillips

  I'm looking for guidance on how to keep my acceptance tests isolated. Right now the issue I'm having with being able to run the tests in parallel is the database records that are manipulated in the tests. I've written helpers that take care of doing inserts and deletes before tests are executed, to make sure the state is correct. But now I can't run them in parallel against the same database without uniquely generating the test data fields for each test. For example. Testing creating a row i'll delete everything where column A = foo and column B = bar Then I'll navigate through the UI in the test and create a record with column A = foo and column B = bar. Testing that a duplicate row is not allowed to be created. I'll insert a row with column A = foo and column B = bar and then use the UI to try and do the exact same thing. This will display an error message in the UI as expected. These tests work perfectly when ran separately and serially. But I can't run them at the same time for fear that one will create or delete a record the other is expecting. Any tips on how to structure them better so they can be run in parallel?

• "Oracle Certified Expert, Java Platform, Enterprise Edition 6 Java Persistence API Developer" Preparation

  - by Matt

  I have been working with Hibernate for a fews years now, and I want to solidify and demonstrate my knowledge by taking the Oracle JPA certification, also known as: "Oracle Certified Expert, Java Platform, Enterprise Edition 6 Java Persistence API Developer (CX-310-094)" There is a training course provided by Oracle: "Building Database Driven Applications with JPA (SL-370-EE6)" But this costs $1800 and I think it would be overkill for my needs. Ideally, I would like a self study guide that will cover everything in the exam. I have looked for books and these seem like possibilities: Pro JPA 2: Mastering the Java Persistence API (Expert's Voice in Java Technology) and Beginning Java EE 6 with GlassFish 3 2nd Edition (Expert's Voice in Java Technology) But these aren't checklist type study guides as far as I am aware. I found the official SCJP study guide very useful, but I think the equivalent text for the JPA exam isn't out yet. If anyone has taken this exam, I would be grateful to hear how you prepared for it. Thanks!

• Perth's ADF Community Event now an open invite

  - by Chris Muir

  Yesterday saw the next ADF Community Event in Perth, and as promised we grew from 15 to 25 attendees (which is going to cause a bit of a problem soon if we keep growing as we're going to run out of powerpoints for laptops). This bimonthly enjoyed presentations from Matthew Carrigy from the Dept of Finance WA on the ADF UI Shell, a small presentation from me about how Fusion Apps uses ADF, and a hands on based on programatically extending ADF BC to call external web services.  For Matt, his first presentation to a user group, with two live demos, all kudos to him for making it look smooth (for the record I hate live demos, I always break something) - thank you Matt! We've already lined up our speakers for the next event in November, and will be inviting yet more customers to this event.  However the event will now move to an open invite, so if you'd like your staff to attend please let me know by emailing chris DOT muir AT oracle DOT com. Alternatively I've had a fair few requests now for an "Intro to ADF" 1 day session so I'll consider this soon.  Certainly if you're interested let me know as this will help organize the event earlier rather than later.

• Inspecting the model in a Rails application

  - by Matt Sherman

  I am learning some Ruby on Rails, and am a newbie. Most of my background is in ASP.net MVC on the back end. As I play with a basic scaffold project, I wonder about this case: you jump into an established Rails project and want to get to know the model. Based on what I have seen so far (again, simple scaffold), the properties for a given class are not immediately revealed. I don't see property accessors on the model classes. I do understand that this is because of the dynamic nature of Ruby and such things are not necessary or even perhaps desirable. Convention over code, I get that. (Am familiar with dynamic concepts, mostly via JS.) But if I am somewhere off in a view, and want to quickly know whether the (eg) Person object has a MiddleName property, how would I find that out? I don't have to go into the migrations, do I?

• Acting as though the laptop Fn key is pressed

  - by Matt

  I have a Fujitsu laptop and all was working fine until I ended teamviewer. On the keyboard it has a numberpad on some of the letters which you press the Fn button to use. The system is acting like I have the Fn key pressed and I get numbers shown when it should be letters. If I press the Fn key the numbers go to letters. The Fn key is not stuck down. Is there a way to reset keyboard settings or a known fix. The operating system is Ubuntu 11.04 Natty.

• Do first impressions really count?

  - by Matt

  So, i am currently writing something up for a college class. Problem is everything is hypothetical. I need some proof. I believe a first impression on a website is imperative so that people actually use it and in my case, buy your product or services as well. Basically I'm wondering has there been any studies that shows how a better web design will increase revenue for any kind of services? I don't just mean selling products like a T-shirt, but labor services as well. If someone wanted their computer fixed and searched for companies that can do so, will a first impression on the website help them make their decision to use your company? Are there any studies like this? White papers maybe? Thanks!
