• Suitable SDK to develop quick game?

  - by gRnt

  I'm currently undertaking a personal project at home that I need to turn around inside the next few months (which working full time and still learning programming makes it a tad difficult). I'm looking for suggestions on SDK's or tools (preferably free or that come with games, similar to steam tools) that I can use to develop a "game". I'm OK with coding but have no 3D development skills at all. I've very little experience with mod tools or SDK's at all but I'm hoping someone can point me in the direction of one that does the following: A decent library of prefab 3D models to build scenes. Ability to add scripting to the scene I've used Unity before and would prefer to continue to do so however I really have the worst 3D skills imaginable and can't waste time learning them. I'd be looking for pre-fab items that are both industrial and possibly more lush environments (trees etc). If it makes any difference (due to licencing and what-not) I WILL NOT be selling this game or marketing it in any way and I am a University Student if any places do educations licences. Another alternative would be to source free 3d models elsewhere but again while I'm still learning I have no idea where to look if someone could point me in the right direction I'll do the rest of the digging. Thanks

• 12.04 No Sound - ALC888 / Radeon 3200HD

  - by Ross

  Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

• Whats the greatest most impressive programing feat you ever witnessed? [closed]

  - by David Reis

  Everyone knows of the old adage that the best programmers can be orders of magnitude better than the average. I've personally seen good code and programmers, but never something so absurd. So the questions is, what is the most impressive feat of programming you ever witnessed or heard of? You can define impressive by: The scope of the task at hand e.g. John single handedly developed the framework for his company, a work comparable in scope to what the other 200 employed were doing combined. Speed e.g. Stu programmed an entire real time multi-tasking app OS on an weekened including its own C compiler and shell command line tools Complexity e.g. Jane rearchitected our entire 10 millon LOC app to work in a cluster of servers. And she did it in an afternoon. Quality e.g. Charles's code had a rate of defects per LOC 100 times lesser than the company average. Furthermore he code was clean and understandable by all. Obviously, the more of these characteristics combined, and the more extreme each of them, the more impressive is the feat. So, let me have it. What's the most absurd feat you can recount? Please provide as much detail as possible and try to avoid urban legends or exaggerations. Post only what you can actually vouch for. Bonus questions: Was the herculean task a one-of, or did the individual regularly amazed people? How do you explain such impressive performance? How was the programmer recognized for such awesome work?

• Observable Adapter

  - by Roman Schindlauer

  .NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.   While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.   Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

• Examples of limitations in IT due to different bit length by design

  - by Alaudo

  I am teaching the course "Introduction in Programming" for the first-year students and would like to find interesting examples where the datatype size in bits, chosen by design, led to certain known restrictions or important values. Here are some examples: Due to the fact that the Bell teleprinter used 7-bit-code (later accepted as ASCII) until now have we often to encode attachments in electronic messages to contain only 7 bit data. Classical limitation of 32-bit address space leads to the 4Gb maximal RAM size available for 32-bit systems and 4Gb maximal file size in FAT32. Do you know some other interesting examples how the choice of the data type (and especially its binary length) influenced the modern IT world. Added after some discussion in comments: I am not going to teach how to overcome limitations. I just want them to know that 1 byte can hold the values from -127..0..+127 o 0..255, 2 bytes cover the range 0..65535 etc by proving examples they know from other sources, like the above-mentioned base64 encoding etc. We are just learning the basic datatypes and I am trying to find a good reference for "how large" these types are.

• How To Use AutoFill on a Google Docs Spreadsheet [Quick Tips]

  - by The Geek

  Have you ever wanted to fill an entire row or column with a series of values? If you’re an Excel user, you can do the same thing in Google Docs. If you haven’t used either, here’s the quick way to do it. Just type in a couple of numbers in sequence… 1 2 3 works pretty well. You could also put them across a row instead of down a column. Then move your mouse over the dot in the corner until the pointer changes, then just drag it downward (or if you are filling a row instead, you can drag it to the right). Let go of the mouse, and your data will be automatically filled in. You could also make it skip by 1 instead, like 2 4 6 8, etc… It all works the same way. Sadly there’s no really advanced options like Excel has, but for most uses, this is good enough. Also, we’re aware this is a very simple tip for most of you, but we’re trying to help the beginners out as well!

• Long term plan of attack to learn math?

  - by zhenka

  I am a web-developer with a desire to expand my skill-set to mathematics relevant to programming. As 2nd career, I am stuck in college doing some of the requirements while working. I was hoping the my education will teach me the needed skills to apply math, however I am quickly finding it to be too much easily-testable breadth-based approach very inefficient for the time invested. For example in my calculus 2 class, the only remotely useful mind expanding experience I had was volumes and areas under the curve. The rest was just monotonous glorified algebra, which while comes easy to me, could be done by software like wolfram alpha within seconds. This is not my idea of learning math. So here I am a frustrated student looking for a way to improve my understanding of math in a way that focuses on application, understanding and maximally removed needless tedium. However I cannot find a good long term study strategy with this approach in mind. So for those of like mind, how would you go about learning the necessary math without worrying too much about stuff a computer can do much better?

• Why is my wireless significantly slower on Ubuntu 12.04, as compared to windows 7?

  - by user89266

  I'm dual booting 12.04, and Win7. Just a tiny bit of background, I'm starting to get more and more interested in programming and 3d modelling, so I'd like to learn more about ubuntu as a result of those interests. Still a complete newb though! Anyway, When downloading on windows, I get 1.5mb/s easy. Now I swap over to Ubuntu, and it hasn't topped 150 kb/s since I installed it some 6 months ago. I'd downloaded most of my programs on windows, so I never really noticed it, but as I'm committing to ubuntu more, it's starting to hinder me. I'm with Shaw, on their Highspeed 20, which gives me 20 mbps down, and 6mbps up. Speedtest.com shows me varying figures somewhat close to what shaw says they give on both windows and ubuntu, which is to be expected, given that it is shaw afterall... So, I don't know what you guys need to know, and I know even less about how to get it to you. Whatever information you guys need, tell me how to get it, how to get it up here, and i'll get it on here! I thought it might be that I'm using a proprietary driver, when an open sourced one would work better? But I really have no clue. Any help would be very much appreciated. Thanks guys!

• I need advice on how to best handle an e-commerce situation

  - by Mohamad

  I recently moved to Brazil and started a small subscription based service company. The payment gateway market is under-developed in Brazil, and implementing a local solution is too expensive for me. My requirements are a payment gateway that will automatically process monthly recurrent billing, and that will allow me to manually charge my customers when needed. They would also have to deal with storage and security. I'm leaning towards manually processing payments myself as a restaurant would do, for example, using small swipe machines. Unfortunately, this would require me to store credit card information and I would rather not, but I feel it's my only option. Can anyone give me advice on how to tackle this problem? Do I have other options? If I decide to store credit card information, what should I keep in mind and how should I go about it? I have moderate skills in programming, and through tenacity I can get most things done. I'm afraid that this might be out of my league, however.

• Gödel, Escher, Bach - Gödel's string

  - by Brad Urani

  In the book Gödel, Escher, Bach: An Eternal Golden Braid by Douglas Hofstadter, the author gives us a representation of the precursor to Gödel's string (Gödel's string's uncle) as: ~Ea,a': (I don't have the book in front of me but I think that's right). All that remains to get Gödel's string is to plug the Gödel number for this string into the free variable a''. What I don't understand is how to get the Gödel number for the functions PROOF-PAIR and ARITHMOQUINE. I understand how to write these functions in a programming language like FlooP (from the book) and could even write them myself in C# or Java, but the scheme that Hofstadter defines for Gödel numbering only applies to TNT (which is just his own syntax for natural number theory) and I don't see any way to write a procedure in TNT since it doesn't have any loops, variable assignments etc. Am I missing the point? Perhaps Gödel's string is not something that can actually be printed, but rather a theoretical string that need not actually be defined? I thought it would be neat to write a computer program that actually prints Gödel's string, or Gödel's string encoded by Gödel numbering (yes, I realize it would have a gazillion digits) but it seems like doing so requires some kind of procedural language and a Gödel numbering system for that procedural language that isn't included in the book. Of course once you had that, you could write a program that plugs random numbers into variable "a" and run procedure PROOF-PAIR on it to test for theoromhood of Gödel's string. If you let it run for a trillion years you might find a derivation that proves Gödel's string.

• At what point would you drop some of your principles of software development for the sake of more money?

  - by MeshMan

  I'd like to throw this question out there to interestingly see where the medium is. I'm going to admit that in my last 12 months, I picked up TDD and a lot of the Agile values in software development. I was so overwhelmed with how much better my development of software became that I would never drop them out of principle. Until...I was offered a contracting role that doubled my take home pay for the year. The company I joined didn't follow any specific methodology, the team hadn't heard of anything like code smells, SOLID, etc., and I certainly wasn't going to get away with spending time doing TDD if the team had never even seen unit testing in practice. Am I a sell out? No, not completely... Code will always been written "cleanly" (as per Uncle Bob's teachings) and the principles of SOLID will always be applied to the code that I write as they are needed. Testing was dropped for me though, the company couldn't afford to have such a unknown handed to the team who quite frankly, even I did create test frameworks, they would never use/maintain the test framework correctly. Using that as an example, what point would you say a developer should never drop his craftsmanship principles for the sake of money/other benefits to them personally? I understand that this can be a very personal opinion on how concerned one is to their own needs, business needs, and the sake of craftsmanship etc. But one can consider that for example testing can be dropped if the company decided they would rather have a test team, than rather understand unit testing in programming, would that be something you could forgive yourself for like I did? So given that there is something you would drop, there usually should be an equal cost in the business that makes up for what you drop - hopefully, unless of course you are pretty much out for lining your own pockets and not community/social collaborating ;). Double your money, go back to RAD? Or walk on, and look for someone doing Agile, and never look back...

• How to show or direct a business analyst to a data modelling subject?

  - by AaronLS

  Our business analysts pushed hard to collect data through a spreadsheet. I am the programmer responsible for importing that data. Usually when they push hard for something like this, I never know how well it will work out until a few weeks later when I have time assigned to work on the task of programming the import of the data. I have tried to do as much as possible along the way, named ranges, data validations, etc. But I usually don't have time to take a detailed look at all the data and compare to the destination in the database to determine how well it matches up. A lot of times there will be maybe a little table of items that somehow I have to relate to something else in the database, but there are not natural or business keys present that would allow me to do so. Make the best of this, trying to write something that can compare strings and make a best guess at it and then go through the effort of creating interfaces for a user to match the imported data to the destination. I feel like if the business analyst was actually creating a data model, they would be forced to think about these relationships, and have an appreciation for the need of natural or business keys to be part of the spreadsheet for the purposes of smoothly importing the data. The closest they come to business analysis is a big flat list of fields, and that would be fine if it were like any other data dictionary and include data types+relationships, but it isn't. They are just a bunch of names. No indication of what type of data they might hold, and it is up to me to guess. When I have pushed for more detail, they say that it is just busy work. How can I explain the importance of data modelling? How can I tell them what it is and how to do it? It feels impossible, because they don't have an appreciation for its importance. They do however, usually have an interest in helping out in whatever way they can, it's just this in particular has never gotten a motivated response.

• Full screen blackout using allegro in codeblocks

  - by Armando Ortiz

  I'm very interested in game programming and I'm taking my first steps alone. So I installed allegro. Although Dev-C++ didn't work, Code::Blocks compiled successfully. I started out with this basic program: #include <allegro.h> int main(){ allegro_init(); install_keyboard(); set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0); readkey(); return 0; } END_OF_MAIN(); The problem comes in when I try to run it. It opens the little window as always, but rapidly blacks out my whole screen. I press any key and it takes me back to the little window telling me that it finished, which means the program worked. But I try any other program with allegro, like: #include <allegro.h> int x = 10; int y = 10; int main(){ allegro_init(); install_keyboard(); set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0); while ( !key[KEY_ESC] ){ clear_keybuf(); acquire_screen(); textout_ex( screen, font, " ", x, y, makecol( 0, 0, 0), makecol( 0, 0, 0) ); if (key[KEY_UP]) --y; else if (key[KEY_DOWN]) ++y; else if (key[KEY_RIGHT]) ++x; else if (key[KEY_LEFT]) --x; textout_ex( screen, font, "@", x, y, makecol( 255, 0, 0), makecol( 0, 0, 0) ); release_screen(); rest(50); } return 0; } END_OF_MAIN(); And the same thing happens over and over again! Is there something I'm doing wrong?

• In the days of modern computing, in 'typical business apps' - why does performance matter?

  - by Prog

  This may seem like an odd question to some of you. I'm a hobbyist Java programmer. I have developed several games, an AI program that creates music, another program for painting, and similar stuff. This is to tell you that I have an experience in programming, but not in professional development of business applications. I see a lot of talk on this site about performance. People often debate what would be the most efficient algorithm in C# to perform a task, or why Python is slow and Java is faster, etc. What I'm trying to understand is: why does this matter? There are specific areas of computing where I see why performance matters: games, where tens of thousands of computations are happening every second in a constant-update loop, or low level systems which other programs rely on, such as OSs and VMs, etc. But for the normal, typical high-level business app, why does performance matter? I can understand why it used to matter, decades ago. Computers were much slower and had much less memory, so you had to think carefully about these things. But today, we have so much memory to spare and computers are so fast: does it actually matter if a particular Java algorithm is O(n^2)? Will it actually make a difference for the end users of this typical business app? When you press a GUI button in a typical business app, and behind the scenes it invokes an O(n^2) algorithm, in these days of modern computing - do you actually feel the inefficiency? My question is split in two: In practice, today does performance matter in a typical normal business program? If it does, please give me real-world examples of places in such an application, where performance and optimizations are important.

• Finding a way to simplify complex queries on legacy application

  - by glenatron

  I am working with an existing application built on Rails 3.1/MySql with much of the work taking place in a JavaScript interface, although the actual platforms are not tremendously relevant here, except in that they give context. The application is powerful, handles a reasonable amount of data and works well. As the number of customers using it and the complexity of the projects they create increases, however, we are starting to run into a few performance problems. As far as I can tell, the source of these problems is that the data represents a tree and it is very hard for ActiveRecord to deterministically know what data it should be retrieving. My model has many relationships like this: Project has_many Nodes has_many GlobalConditions Node has_one Parent has_many Nodes has_many WeightingFactors through NodeFactors has_many Tags through NodeTags GlobalCondition has_many Nodes ( referenced by Id, rather than replicating tree ) WeightingFactor has_many Nodes through NodeFactors Tag has_many Nodes through NodeTags The whole system has something in the region of thirty types which optionally hang off one or many nodes in the tree. My question is: What can I do to retrieve and construct this data faster? Having worked a lot with .Net, if I was in a similar situation there, I would look at building up a Stored Procedure to pull everything out of the database in one go but I would prefer to keep my logic in the application and from what I can tell it would be hard to take the queried data and build ActiveRecord objects from it without losing their integrity, which would cause more problems than it solves. It has also occurred to me that I could bunch the data up and send some of it across asynchronously, which would not improve performance but would improve the user perception of performance. However if sections of the data appeared after page load that could also be quite confusing. I am wondering whether it would be a useful strategy to make everything aware of it's parent project, so that one could pull all the records for that project and then build up the relationships later, but given the ubiquity of complex trees in day to day programming life I wouldn't be surprised if there were some better design patterns or standard approaches to this type of situation that I am not well versed in.

• Creating user UI using Flixel

  - by Jamie Read

  I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives. What I am trying to do is add a Start Screen before actually loading the game. I have a create function that adds all the game elements to the stage: override public function create():void // all game elements { How can I add this pre-load Start Screen? I'm not sure if I have to add in the code to this create function or somewhere else and what code to actually add. Eventually I would also like to add saving, loading, options and upgrades too. So any advice with that would be great. Here is my main game.as: package { import org.flixel.*; public class Game extends FlxGame { private const resolution:FlxPoint = new FlxPoint(640, 480); private const zoom:uint = 2; private const fps:uint = 60; public function Game() { super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom); FlxG.flashFramerate = fps; } } } Thanks.

• What happened to the Journal of Game Development?

  - by Ricket

  The lengthy mission statement from its website states: The lack of game-specific research has prevented many in the academic community from embracing game development as a serious field of study. The Journal of Game Development (JOGD), however, provides a much-needed, peer-reviewed, medium of communication and the raison d'etre for serious academic research focused solely on game-related issues. The JOGD provides the vehicle for disseminating research and findings indigenous to the game development industry. It is an outlet for peer-reviewed research that will help validate the work and garner acceptance for the study of game development by the academic community. JOGD will serve both the game development industry and academic community by presenting leading-edge, original research, and theoretical underpinnings that detail the most recent findings in related academic disciplines, hardware, software, and technology that will directly affect the way games are conceived, developed, produced, and delivered. The Journal of Game Development was established in 2003. It's hard to find any information about the issues but at four issues per year, I estimate the last issue was distributed sometime in 2005 or 2006. It had a good editorial board of college professors and a founding editor from Ubisoft. The list of articles looks good. The price was reasonable. So what happened to it? Its website recently went down but you can see the last Archive.org version. The editor-in-chief is a professor at my school so I intend to ask him in person in a week or two, but I thought I'd see what you might be able to dig up about it first. Of course I will be sure to add an answer with his official word on the matter at that time.

• Interpreting Others' Source Code

  - by Maxpm

  Note: I am aware of this question. This question is a bit more specific and in-depth, however, focusing on reading the actual code rather than debugging it or asking the author. As a student in an introductory-level computer science class, my friends occasionally ask me to help them with their assignments. Programming is something I'm very proud of, so I'm always happy to oblige. However, I usually have difficulty interpreting their source code. Sometimes this is due to a strange or inconsistent style, sometimes it's due to strange design requirements specified in the assignment, and sometimes it's just due to my stupidity. In any case, I end up looking like an idiot staring at the screen for several minutes saying "Uh..." I usually check for the common errors first - missing semicolons or parentheses, using commas instead of extractor operators, etc. The trouble comes when that fails. I often can't step through with a debugger because it's a syntax error, and I often can't ask the author because he/she him/herself doesn't understand the design decisions. How do you typically read the source code of others? Do you read through the code from top-down, or do you follow each function as it's called? How do you know when to say "It's time to refactor?"

• How to use the Raring/Saucy netboot installer to install Precise?

  - by mikepurvis

  We have a Haswell motherboard with onboard ethernet controllers which are not supported in the Precise (3.2) kernel. However, we're using netboot installation, and we'd really like to stick with the LTS version. Once the Precise install is completed, we can install the linux-generic-lts-saucy package, which gets us the ethernet hardware support which is ultimately required. So, our options are: Plug in a USB-Ethernet (or even wifi) dongle, perform the install that way. Modify the Precise installer to somehow include the required driver (a udeb, or some early_command invocation?) Modify the Raring installer (3.8 kernel, which supports the device) to instead install Precise. If it's possible the third option seems like the simplest and most logical to me. Now, we are already using the precise-updates installer (Aug 2013), as opposed to the original April 2012 installer. However, the precise-updates installer still appears to use the 3.2 kernel. I'm already comfortable with preseeding and modifying the netboot initrd. So my question is, can I somehow modify the Raring/Saucy netboot initrd to instead install Precise? Thanks.

• How does a one-man developer do its games' sounds?

  - by Gustavo Maciel

  Before anything, that's not a "oh, where can I find resources?" question. Well, I've been curious about one thing in the indie games industry. For the development of the game, such tasks like game design, art, sketches, code programming and etc can be easily done by just one person. You can just take up a paper and pencil and you're a game designer. You can just take software like Photoshop or Paint and you're an artist, a scanner and you're a sketcher, a compiler and you're a programmer. For sound it's different. You may tell me: Well, follow the line, take a lot of instruments and record it. But all we know that things don't work this way. I can list up some changes for us: External noises are a big problem, sound effects can't be made with instruments, it can't sound like a recorded and clipped sound. Well I can imagine how they do this in large companies, with such big studios and etc. But to summarise, my question is: What's the best way for a one-man indie to do all its sound? Does he have to synthesize everything? Record and buy some crazy program for editing sounds?

• Server-side Architecture for Online Game

  - by Draiken

  Hi, basically I have a game client that has communicate with a server for almost every action it takes, the game is in Java (using LWJGL) and right now I will start making the server. The base of the game is normally one client communicating with the server alone, but I will require later on for several clients to work together for some functionalities. I've already read how authentication server should be sepparated and I intend on doing it. The problem is I am completely inexperienced in this kind of server-side programming, all I've ever programmed were JSF web applications. I imagine I'll do socket connections for pretty much every game communication since HTML is very slow, but I still don't really know where to start on my server. I would appreciate reading material or guidelines on where to start, what architecture should the game server have and maybe some suggestions on frameworks that could help me getting the client-server communication. I've looked into JNAG but I have no experience with this kind of thing, so I can't really tell if it is a solid and good messaging layer. Any help is appreciated... Thanks !

• MaaS minimum requirements with juju-jitsu?

  - by Christopher Shen Mu Long

  I've browsed through so many different sites and found so much contradictory information. As I am getting tired of this and do belive this question affects many other users, so I would like to collect the "once and for all times" answer. Unfortunately, the documentation on MaaS and Juju is ... well, not the best, sorry to say that. What are the minimum system requirements for setting up a MaaS cluster, which is going to be orchestrated with juju-jitsu? Do they need to have the exact system specifications or can I just combine different hardware? What are the minimum requirements for the master machine? E.g. "You need at least 8GB of RAM, a dual core CPU with at least 3.0 GHz." How many machines to I need to deploy MaaS on? I've read six machines, nine machines, and so on. I clearly want to know: "You need one for the Master and e.g. five nodes." Do I need to attach as many NICs (network interface cards) to my master machine as there are nodes, or can I simply attach two NICs and a switch? One NIC for connecting to the internet, one for handling the MaaS tasks, connected to a switch, which connects my nodes to the master? Is Juju now ready for local deployment? The last time I experimented with juju and had to reboot my machine, the services orchestrated by juju were gone. This was an issue I also found on the official juju site. Unfortunately, as mentioned above, the documentation is not the best, so I could not find the necessary info on that again. So: Can I use juju on a local environment or will a reboot break my setup?

• Presenting the Cloud in a Different Way

  - by BuckWoody

  I had the honor of presenting the Developers at the Portland PASS chapter, and decided to go a different way than just using PowerPoint Slides…. (click on any picture to enlarge) The point is that when you need to get a point across, it’s OK to change tactics to make sure the information sticks. In this case, I decided to make the audience the PowerPoint. I used a few props to show the various paradigms we use to describe what the industry uses for the word “cloud” First, we talked about Infrastructure as a Service. I picked a gentleman who didn’t quite fit the hard hat and safety vest I picked out for him. Notice our “user” as she accesses our “Server” (complete with tray and glass) which has been virtualized.    Software as a service comes next. In this case, the user and potentially even customers just access software (represented here as a Windows ME box…) remotely – everything is virtualized. Finally, Platform as a Service – Yup, Platform shoes as a necklace, and a tie-dye shirt to represent the 70’s – a decade when mainframes used stateless programming as well. Notice also the components of Windows Azure – Compute (Keyboard) Application Fabric (Toy Bus) and Storage (Bucket).   And at the end of the day, it’s all about serving those customers…
