• External table and preprocessor for loading LOBs

  - by David Allan

  I was using the COLUMN TRANSFORMS syntax to load LOBs into Oracle using the Oracle external which is a handy way of doing several stuff - from loading LOBs from the filesystem to having constants as fields. In OWB you can use unbound external tables to define an external table using your own arbitrary access parameters - I blogged a while back on this for doing preprocessing before it was added into OWB 11gR2. For loading LOBs using the COLUMN TRANSFORMS syntax have a read through this post on loading CLOB, BLOB or any LOB, the files to load can be specified as a field that is a filename field, the content of this file will be the LOB data. So using the example from the linked post, you can define the columns; Then define the access parameters - if you go the unbound external table route you can can put whatever you want in here (your external table get out of jail free card); This will let you read the LOB files fromn the filesystem and use the external table in a mapping. Pushing the envelope a little further I then thought about marrying together the preprocessor with the COLUMN TRANSFORMS, this would have let me have a shell script for example as the preprocessor which listed the contents of a directory and let me read the files as LOBs via an external table. Unfortunately that doesn't quote work - there is now a bug/enhancement logged, so one day maybe. So I'm afraid my blog title was a little bit of a teaser....

• MightyMintyBoost Is a 3-in-1 Gadget Charger

  - by ETC

  If you’re looking for a versatile battery booster, this DIY 3-in-1 solar/usb/wall current charger known as the MightyMintyBoost will top of your phone, mp3 player, and other gadgets with ease. Instructables user Honus didn’t just build the MightMintyBoost to geek out and show off his electronics project skills (although it’s certainly a nifty little project to do so), he’s serious about solar power and the impact clean energy has: Apple has sold over 30 million iPodTouch/iPhone units- imagine charging all of them via solar power…. If every iPhone/iPodTouch sold was fully charged every day (averaging the battery capacity) via solar power instead of fossil fuel power we would save approximately 50.644gWh of energy, roughly equivalent to 75,965,625 lbs. of CO2 in the atmosphere per year. Granted that’s a best case scenario (assuming you can get enough sunlight per day and approximately 1.5 lbs. CO2 produced per kWh used.) Of course, that doesn’t even figure in all the other iPods, cell phones, PDAs, microcontrollers (I use it to power my Arduino projects) and other USB devices that can be powered by this charger- one little solar cell charger may not seem like it can make a difference but add all those millions of devices together and that’s a lot of energy! His MightyMintyBoost is a battery booster for devices that can charge via USB and it accepts incoming current from the solar panel on top (or, on cloudy days can be charged via a wall charger or the USB port on your computer).

• WordPress is now nicely supported on SQL Server (and SQL Azure for that matter)

  - by Eric Nelson

  WordPress is enormously popular for blogs and full websites thanks to an awesome eco system which has built up around it, the simplicity (relatively) of getting it up and running plus the flexibility to “bend it” in all sorts of directions. When I say bend, check out the following which are all WordPress sites My “back up blog” http://iupdateable.wordpress.com/  My groups “odd site” :) http://ubelly.com My favourite “cheap games” site http://www.frugalgaming.co.uk/  WordPress users typically run their sites on Linux and MySQL, although PHP (the language in which WordPress is written) can be happily run on Windows. Both fine technologies in their own right, but for me (and probably a fair few others) I would love to use WordPress but with the technologies I know best (aka Windows, IIS and SQL Server). However, that has proven to be actually rather tricky in practice to get working – until now. Earlier last month OmniTI released a patch for WordPress which provides SQL Server and SQL Azure support.  In parallel with that some fine folks inside Microsoft have also created http://wordpress.visitmix.com which contains information about running WordPress on the Microsoft platform with a particular focus on SQL Server and SQL Azure.  Top stuff!

• What is the correct and most efficient approach of streaming vertex data?

  - by Martijn Courteaux

  Usually, I do this in my current OpenGL ES project (for iOS): Initialization: Create two VBO's and one IndexBuffer (since I will use the same indices), same size. Create two VAO's and configure them, both bound to the same Index Buffer. Each frame: Choose a VBO/VAO couple. (Different from the previous frame, so I'm alternating.) Bind that VBO Upload new data using glBufferSubData(GL_ARRAY_BUFFER, ...). Bind the VAO Render my stuff using glDrawElements(GL_***, ...); Unbind the VAO However, someone told me to avoid uploading data (step 3) and render immediately the new data (step 5). I should avoid this, because the glDrawElements call will stall until the buffer is effectively uploaded to VRAM. So he suggested to draw all my geometry I uploaded the previous frame and upload in the current frame what will be drawn in the next frame. Thus, everything is rendered with the delay of one frame. Is this true or am I using the good approach to work with streaming vertex data? (I do know that the pipeline will stall the other way around. Ie: when you draw and immediately try to change the buffer data. But I'm not doing that, since I implemented double buffering.)

The challenge is to write at least two blog posts a week for 12 weeks over the summer. Consider this challenge accepted. So, what can we expect coming up? I still have the Kinect v2 Alpha kit. Some of you may have seen me use it in talks. I need to make some major API changes in The Krewe WP8 App. Plus, I may have Xamarin on board to help with getting the app to the other platforms. I am determined to learn F#, and I'm taking all of you with me. I am teaching a college course this summer. I want to post some commentary on that side of training. I am sure some biometric stuff will come up. Anything else you guys may want. I have created tasks on my schedule to get a new blog post up no later than every Tuesday and Friday. We'll see how that goes. Wish me luck.

• Visage

  - by Geertjan

  Raj, the Chennai JUG lead, together with others from that JUG, is interested in Visage, the JavaFX script language closely associated with Stephen Chin. He sent me the related lexer and parser and I started by having a look at them in the new version of ANTLRWorks being developed by Sam Harwell (who demonstrated it very effectively during JavaOne): Notice how the lexer and parser are shown in a tree structure, as well as in a cool syntax diagram. Next, I downloaded a bunch of JARs from here, so that packages such as from "com.sun.tools.mjavac" can be used, i.e., these are Visage-specific packages that aren't found anywhere except in the location below: http://code.google.com/p/visage/wiki/GettingStarted It turns out that there's also a Visage NetBeans plugin out there: http://code.google.com/p/visage/source/browse/?repo=netbeans-plugin Rather than recreating everything from scratch, i.e., generating ANTLR Java classes from the lexer and parser, I copied a lot of stuff from the site above and now a file Raj sent me looks as follows, i.e., basic syntax coloring is shown: For anyone wanting to seriously support Visage in NetBeans IDE, I recommend downloading the existing Visage NetBeans plugin above, rather than creating everything yourself from scratch, and then figuring out how to use that code in some way, i.e., add the JARs I pointed to above, and work on its build.xml file, which could be frustrating in the beginning, but there's no point in recreating everything if everything already exists.

• What is a good support knowledge base tool?

  - by Guillaume

  I have been searching for a tool to help my team organize its knowledge for resolving recurring support cases. I know this question will probably be closed, but I'll try my change anyway because I know that I can have some good answers about that. Context: our team is developing and supporting an huge applications (lots of different screens and workflow processes. We already have a good tool for managing our documentation, but we are struggling with support cases. Support action involve often quite a lot of manual steps to fix stuff and the knowledge for these actions is more 'oral transmission' than modern tools. We need an efficient way to store them in a knowledge base to be able to retrieve similar cases based on patterns (a stacktrace, an error message, a component name, a workflow step, ...) and ranked by similarity. Our wiki search is not very powerful when it come to this kind of search and the team members don't want to 'waste' time writing a report that will never be found... Do you know efficient knowledge base tool for this kind of use case ?

• SQL SERVER – Grouping by Multiple Columns to Single Column as A String

  - by pinaldave

  One of the most common questions I receive in email is how to group multiple column data in comma separate values in a single row grouping by another column. I have previously blogged about it in following two blog posts. However, both aren’t addressing the following exact problem. Comma Separated Values (CSV) from Table Column Comma Separated Values (CSV) from Table Column – Part 2 The question comes in many different formats but in following image I am demonstrating the same question in simple words. This is the most popular question on my Facebook page as well. (Example) Here is the sample script to build the sample dataset. CREATE TABLE TestTable (ID INT, Col VARCHAR(4)) GO INSERT INTO TestTable (ID, Col) SELECT 1, 'A' UNION ALL SELECT 1, 'B' UNION ALL SELECT 1, 'C' UNION ALL SELECT 2, 'A' UNION ALL SELECT 2, 'B' UNION ALL SELECT 2, 'C' UNION ALL SELECT 2, 'D' UNION ALL SELECT 2, 'E' GO SELECT * FROM TestTable GO Here is the solution which will build an answer to the above question. -- Get CSV values SELECT t.ID, STUFF( (SELECT ',' + s.Col FROM TestTable s WHERE s.ID = t.ID FOR XML PATH('')),1,1,'') AS CSV FROM TestTable AS t GROUP BY t.ID GO I hope this is an easy solution. I am going to point to this blog post in the future for all the similar questions. Final Clean Up Act -- Clean up DROP TABLE TestTable GO Here is the question back to you - Is there any better way to write above script? Please leave a comment and I will write a separate blog post with due credit.

• In an Entity/Component system, can component data be implemented as a simple array of key-value pairs? [on hold]

  - by 010110110101

  I'm trying to wrap my head around how to organize components in an Entity Component Systems once everything in the current scene/level is loaded in memory. (I'm a hobbyist BTW) Some people seem to implement the Entity as an object that contains a list of of "Component" objects. Components contain data organized as an array of key-value pairs. Where the value is serialized "somehow". (pseudocode is loosely in C# for brevity) class Entity { Guid _id; List<Component> _components; } class Component { List<ComponentAttributeValue> _attributes; } class ComponentAttributeValue { string AttributeName; object AttributeValue; } Others describe Components as an in-memory "table". An entity acquires the component by having its key placed in a table. The attributes of the component-entity instance are like the columns in a table class Renderable_Component { List<RenderableComponentAttributeValue> _entities; } class RenderableComponentAttributeValue { Guid entityId; matrix4 transformation; // other stuff for rendering // everything is strongly typed } Others describe this actually as a table. (and such tables sound like an EAV database schema BTW) (and the value is serialized "somehow") Render_Component_Table ---------------- Entity Id Attribute Name Attribute Value and when brought into running code: class Entity { Guid _id; Dictionary<string, object> _attributes; } My specific question is: Given various components, (Renderable, Positionable, Explodeable, Hideable, etc) and given that each component has an attribute with a particular name, (TRANSLATION_MATRIX, PARTICLE_EMISSION_VELOCITY, CAN_HIDE, FAVORITE_COLOR, etc) should: an entity contain a list of components where each component, in turn, has their own array of named attributes with values serialized somehow or should components exist as in-memory tables of entity references and associated with each "row" there are "columns" representing the attribute with values that are specific to each entity instance and are strongly typed or all attributes be stored in an entity as a singular array of named attributes with values serialized somehow (could have name collisions) or something else???

• Ubuntu's security, Gaming, X server, situation [closed]

  - by ShortCircuit

  Little background story. So when I first heard about the NSA spying on people I wasn't surprised, it also was the reason why I switched to Ubuntu. (Full time) It had it's disadvantages when comparing to Windows and it's AAA games and other stuff. My best friend is somewhat upset about me, using full time Ubuntu, because we play a game named "Dayz (an addon for Arma II)" and WineHQ wasn't of any help. Not to mention that he keeps asking me if WineHQ can run Dayz, but he clearly doesn't understand the situation of WineHQ, that it's free, that you have to be happy with what you got at the moment. (I'm not going to dual boot because, how else is gaming on Ubuntu/Linux going to happen?) But whenever I was in a nasty situation where I could do something so simply on Windows and not/hard on Ubuntu, I always thought "It's almost virus free, It's free, No one is spying on me." My Questions: My English isn't all that good, so could some one simplify/explain what the hell is going on the below standing link? Ubuntu Spyware: What to Do? https://www.gnu.org/philosophy/ubuntu-spyware.html When will gaming on Linux/Ubuntu be a real thing? I've heard that the X server's code is a mess and that Wayland will replace X server. When/will this come reality? (I might have understood this wrong.)

• Controlling a GameObject from another GameObject's script component

  - by OhMrBigshot

  I'm creating a game where when starting the game, a Cube is duplicated GridSize * GridSize times when the game starts. Now, after the cubes are duplicated I want to attach a variable to them, say "Flag" which is a bool, from another script component (let's say I have a Prefab that generates the cloned cubes). In short, I have something like this: CreateTiles.cs : Attached to Prefab void Start() { createMyTiles(); // a function that clones the tiles flagRandomTiles(); // a function that (what I'm trying to do) "Flags" 10 random cubes } CubeBehavior.cs : Attached to each Cube public bool hasFlag; // other stuff Now, I want flagRandomTiles() to set a Cube's hasFlag property via code, assuming I have access to them via a GameObject[] array. Here's what I've tried: Cubes[x].hasFlag = true; - No access. Making a function such as Cubes[x].setHasFlag(true) - still no access. Initializing Cubes as a CubeBehavior object array, then doing the above - GameObjects can't be converted to CubeBehaviors - I get this error when I try to assign the Cubes into the array. How do I do this?

• Stuck With grub rescue> console

  - by rej santos

  Here is the background of my issue: I just recently installed the latest version of Ubuntu along side with Windows 8 Enterprise. However upon checking the disk size, it seems that some of the portions of the hd memory were gone so I decided to check the disk partition and have seen that is was being used by another file system. Thinking that the Ubuntu takes it boots stuff from my drive C: , I deleted that partition and formated so I can use it to store some movies, music etc. Now, as I switch on my machine, I am stucked with: error: unknown filesystem grub rescue> I googled a lot and saw the following command which seems no to me like sudo, chainloader etc, all of these command only returns unknown command in the console. What I just wanted is to boot from my Windows 8 OS. Just to add, I can't open the BIOS menu so I could choose what media to boot. As I open my machine it automatically takes me to grub rescue console. Here are the thing I already have: Ubuntu Installation Disk Windows 8 System repair Disk I just don't know how to boot into these things. Let me know what to do.

• nVidia Settings: Overriding anti-aliasing causes delay

  - by Kalle Elmér

  I'm using Google Sketchup on ubuntu 12.04 with Wine 1.4. It works flawlessly out of the box, but anti-aliasing is causing some problems. I can override anti-aliasing settings using the nVidia X Server Settings utility, which results in a great-looking image. However, the view doesn't seem to update properly. It's a bit hard to explain, but if I do something (e.g. zooming) the changes won't appear in the view until I take another action. in other words, there seems to be a delay of one "action". Take this example. The mouse wheel is moved one notch to zoom in one step. Nothing happens. An object is selected by clicking. The new zoom is rendered but the selection box doesn't appear. An empty area is clicked. The selection box appears. Is there something that I can do to solve the problem? Could I force the GPU to redraw that view with a certain interval, or is there some other solution? I really like anti-aliasing, but it's hard to use when drawing stuff.

• System boots in console + login loop

  - by Imagicien

  I messed up my system while trying to fix permission problems for setting up a LAMP local server. I tried this solution: How to avoid using sudo when working in /var/www? without success. Then I saw this solution: Permissions issue: how can Apache access files in my Home directory? I understood that I had to change the permissions of my root directory (among others), so I executed: sudo chmod 710 / I also changed the user group on / to www-data. I also did these operations on /home. I'm pretty sure one of those commands broke something, because it's the last commands I executed, and after that, my system showed strange/broken behavior: Firefox stopped showing pages Some icons got replaced by an red X icon (meaning "Icon not found" I guess) Applications refused to launch (no reaction) After rebooting: I got a strange graphical message talking about not being able to mount something, asking me if I wanted to wait, and talking about /tmp (I forgot the message since I was in shock) My system now boots in console, and when I login, it flashes unsignificant stuff* before re-asking me to login. My important data is on Ubuntu One. I'd prefer not having to reinstall from scratch. Is there a way to regain access to my system? Thanks a lot for your help. *Looks like a terminal header with the name of the OS and other info. Doesn't seem important.

• I need advice on laptop purchase for university [closed]

  - by Systemic33

  I'm currently in University studying Computer Science/IT/Information Technology. And this first year i've managed to do with the laptop I had; an ASUS Eee PC 1000H with a 10.1" screen. But this is getting way too underpowered and small for programming more than just quick programming introduction excercises. So I'm looking to buy a more suitable laptop. It's not supposed to be a desktop replacement though, since I've got a pretty good desktop already with a 24" monitor. So the kinda laptop I want to buy is one suited for university. If this bears any significance, I'm working in Java atm, but I will likely work with lots of other things incl. web development. I'm looking to spend about $1700 plus/minus. And it should be powerful/big enough for working on programming projects as well as the usual university stuff like MATLAB, Maple, etc out "in the field", and sometimes for maybe a week when visiting my parents. What I'm looking at right now is the ASUS Zenbook UX31A with the 1920 x 1080 resolution on 13.3" IPS display. But I'm kinda nervous that this will be too petite for programming. In essence i'm looking for a powerfull computer, that has good enough battery, and looks good. I would love suggestions or any type of feedback, either with maybe a better choice, or input on how its like programming on 13" laptops. Very much thanks in advance for anyone who even went through all that! PS. I don't want a mac, or my inner karma would commit Seppuku xD But experiences from working on the 13" Macbook Air would kinda be equivalent to the Zenbook i'm considering, so I would love to hear that. tl;dr The quick brown fox jumps over the lazy dog ;)

• Is my JS/Jquery methodology good?

  - by absentx

  I always struggle with which of the stack sites is best to post "questions of theory" like this, but I think programmers is the best, if not, as usual a mod will move it etc... I am seeking critique on what has become my normal methodology of writing javascript. I have become heavily reliant on the Jquery library, but I think this has helped me learn the native language better also. Anyways, please critique the following style of JS coding...buried are a lot of questions of scope, if you could point out the strengths and weaknesses of this style I would appreciate it. var critique ={ start: function(){ globalness = 'GLOBAL-GLOBAL'; //available to all critique's methods var notglobalness = 'LOCAL-LOCAL';// only available to critiques start method //am I using the "method" teminology properly here?? $('#stuff').on('click','a.closer-target',function(){ $target = $(this); if($target.hasClass('active')){ $target.removeClass('active'); } else{ $target.addClass('active'); critique.madness($target); } }) console.log(notglobalness+': at least I am useful at home'); console.log('note here that: '+notglobalness+' is no longer available after this point, lets continue on:'); critique.madness(notglobalness); }, madness: function($e){ // do a bunch of awesomeness with $e //but continue to keep it seperate because you think its best to keep things isolated. //send to the next function when complete here console.log('here is globalness, which is still available from the start method of critique!! ' + globalness); console.log('lets see if the globalness carries on to a new var object!!'); console.log('the locally isolated variable of NOTGLOBALNESS is available here because it was passed to this method, lets show it:'+$e); carryOn.start(); } } //end critique var carryOn={ start: function(){ console.log('any chance critique.globalness will work here??? lets see: ' +globalness); console.log('it absolutely does'); } } $(document).ready(critique.start);

• An adequate message authentication code for REST

  - by Andras Zoltan

  My REST service currently uses SCRAM authentication to issue tokens for callers and users. We have the ability to revoke caller privileges and ban IPs, as well as impose quotas to any type of request. One thing that I haven't implemented, however, is MAC for requests. As I've thought about it more, for some requests I think this is needed, because otherwise tokens can be stolen and before we identify this and deactivate the associated caller account, some damage could be done to our user accounts. In many systems the MAC is generated from the body or query string of the request, however this is difficult to implement as I'm using the ASP.Net Web API and don't want to read the body twice. Equally importantly I want to keep it simple for callers to access the service. So what I'm thinking is to have a MAC calculated on: the url, possibly minus query string the verb the request ip (potentially is a barrier on some mobile devices though) utc date and time when the client issues the request. For the last one I would have the client send that string in a request header, of course - and I can use it to decide whether the request is 'fresh' enough. My thinking is that whilst this doesn't prevent message body tampering it does prevent using a model request to use as a template for different requests later on by a malicious third party. I believe only the most aggressive man in the middle attack would be able to subvert this, and I don't think our services offer any information or ability that is valuable enough to warrant that. The services will use SSL as well, for sensitive stuff. And if I do this, then I'll be using HMAC-SHA-256 and issuing private keys for HMAC appropriately. Does this sound enough? Have I missed anything? I don't think I'm a beginner when it comes to security, but when working on it I always. am shrouded in doubt, so I appreciate having this community to call upon!

• How is"cloud computing"different from "client-server"?

  - by BellevueBob

  Watching a CEO for a new "cloud computing" company describe his company on a finance TV program today, he said something like "Cloud computing is superior to old-fashioned client-server computing". Now I'm confused. Can someone please explain what "cloud computing" means in contrast to client-server? As far as I understand it, cloud computing is more of a network services model, such that I do not own or maintain the physical hardware. The "cloud" is all the back-end stuff. But I still might have an application that communicates with that "cloud" environment. And if I run a web site presents a form that a user fills out, pushes a button on the page, and returns some report that was generated by the web server, isn't that the same as "cloud" computing? And would you not consider my web browser as the "client"? Please note my question is specific to the concept of "cloud computing" with respect to "client-server". Sorry if this is an inappropriate question for this site; it's the one closest in the Stack universe and this is my first time here. I'm an old timer, programming since mainframe days in the late 70's.

• How do you properly organize a commercial game?

  - by Reactorcore

  For the past months I've been studying programming and I've finally learned how to code, but one thing that is confusing me is how to properly organize the design of a game project - code wise. The game I'm building is a pretty standard commercial game. It has the basic components of a normal game: A world, characters and items interacting with each other and all of this is run by game manager. Basically you play as a hero in a world and do stuff. Fight, explore and interact. Think of your standard adventure game that starts off with an intro, goes to the menu system, then gets into the game and back to the menu. Pretty much like 99% of any commercial game or otherwise serious game projects. Thats what I'm aiming at. The problem is: How do you properly code a commercial game architecture? How do you organize it? How do you make it not become unmaintainable spaghetti code? What specific things to keep in mind when building this, codewise? How you can help me: a) Please tell how do you code your own game projects. What is your thought-process when designing the architecture? b) Recommend books, blogs, tutorials, videos or anything else on how to organize a commercial video game. c) Give hints and tips on do's/don'ts when building a game, codewise. Please help!

• Why is "googlehosted.com" in the DNS records for our website after signing up for DDOS protection?

  - by Blake Nic

  Recently we had to get some DDOS protection for our website because of the large attacks we were seeing after getting a bit of popularity. We handed over our domain and hosting information to our DDOS protection provider. It worked perfectly but I have a question. On our DNS records we have the Host and Answer and Type. The host has our domain name there. The answer is this: SOMETEXTXXXX.dv.googlehosted.com. And when I copy and paste it into my browser it gives me a 404 error. But our website still loads and functions as it should. I don't understand why it would need this? I asked them about this and they said it is a method for DDOS protection and the other IPs are the reverse proxy (the other IPs give a 404 error too). Can anyone expand on this more please. How does all this tie in together and make the internet browser know where to point the person with all these reverse proxies and stuff I don't understand. Here is an image for reference:

• How could I change the colour of the menu font in Lubuntu?

  - by cipricus

  I use Lubuntu 12.04 and I have become obsessed with the looks of it! There is a type of themes that I especially want to use (flat, light), all related to the Elegant brit theme. On my desktop it looks like: As I want to replace the dominating orange with blue, I would prefer even more the theme Elegant Brit re-Revisited The problem is that both of them have a problem with my system tray, a white background appears: A theme that is almost identical to the orange one, but has no problem with the system tray is called Elegant Blackle. I have tried to use this one and replaced the gtk2 folder in its main folder with the gtk2 folder from Elegant Brit re-Revisited. The result is an improvement for me, as I have eliminated a part of the orange stuff with a decent blue :). The orange now appears only with the gtk3 apps, which is rather amusing. Migrating also the gtk3 folder from the blue to the orange theme would bring the sys tray problem too: it is something related to that gtk3 folder. But this is another matter. Now I have something very close to what I want. But I especially would like to have a feature that was present in the Elegant Blackle theme and now is gone as its gtk2 folder was replaced by that of the blue theme: the black font of the menus, instead of the blueish ones. Could anyone instruct me what is to be changed in the gtk2 folder of the Elegant Brit re-Revisited theme so as to make the menus look like this (like they do in Elegant Blackle with its original gtk2 folder): and not like this? : (on my display this blue is more whitish). An alternative and ideal solution would be knowing how to edit the Elegant Brit re-Revisited theme so as to remove the systray problem or, maybe easier, to edit the orange colour of Elegant Blackle theme to as to be completely replaced by the blue of the other one.

• Compiled code spreadsheet-like cell management? (auto-updating)

  - by proGrammar

  Okay so I am fully aware how spreadsheets manage cells, they build dependency graphs where when one cell changes it tells all the other cells that are dependent on it that it changed. So they can from there update. How they update I think involves either re-evaluating the formulas stored as strings, or re-evaluating the abstract syntax tree which I think is stored differently and might be faster. Something like that. What I'm looking to do is manage a few variables in my code so I don't have to update them in the correct way, which would be a nightmare. But I also want it much faster than spreadsheets. And since I'm not looking for any functionality as great as are in these spreadsheets, I just figured from that thought point that there has to be a way to have a very fast implementation of this functionality. Especially since I don't have to modify cells after compiling unless that would be an option. I'm very new to programming so I have no idea. One example might be to have a code-generator that generates code that does this for me. But I have no clue what the generated code would look like. Specifically, how exactly would variables inform others that they need to update, and what do those variables do to update? I'm looking for any kind of ideas. Programming is not my job but nonetheless I was hoping to have some kind of system like this that would greatly help me with some stuff. Of course I have been programming plenty lately so I can still program. I just don't have the full scope on things. I'm looking for any kind of ideas, thank you very much in advance! Also, please help me with the tags. I know C# and Java mainly and I'm hoping to implement this in either of those languages and I'm hoping this can stay in those tags. Forcing this into some kind of spreadsheet tag wouldn't be accurate.

• Need Guidance Making HTML5 Canvas Game Engine

  - by Scriptonaut

  So I have some free time this winter break and want to build a simple 2d HTML5 canvas game engine. Mostly a physics engine that will dictate the way objects move and interact(collisions, etc). I made a basic game here: http://caidenhome.com/HTML%205/pong.html and would like to make more, and thought that this would be a good reason to make a simple framework for this stuff. Here are some questions: Does the scripting language have to be Javascript? What about Ruby? I will probably write it with jQuery because of the selecting powers, but I'm curious either way. Are there any great guides you guys know of? I want a fast guide that will help me bust out this engine sometime in the next 2 weeks, hopefully sooner. What are some good conventions I should be aware of? What's the best way to get sound? At the moment I'm using something like this: var audioElement = document.createElement('audio'); audioElement.setAttribute('src', 'paddle_col.wav'); audioElement.load(); I'm interested in making this engine lightweight and extremely efficient, I will do whatever it takes to get great speeds and processing power. I know this question is fairly vague, but I just need a push in the right direction. Thanks :)

• Architecture Standards &ndash; BPMN vs. BPEL for Business Process Management

  - by pat.shepherd

  I get asked often which business process standard an organization should use; BPMN or BPEL?  As I explain to folks, they both have strengths.  Here is a great article that helps understand the benefits of both and where to use them.  The good news is that, with Oracle SOA Suite and BPM suite, you have the option and flexibility to use both in the same SCA model and runtime container.  Good stuff. Here is the great article that Mark Nelson wrote: The right tool for the right job BPEL and BPMN are both ‘languages’ or ‘notations’ for describing and executing business processes. Both are open standards. Most business process engines will support one or the other of these languages. Oracle however has chosen to support both and treat them as equals. This means that you have the freedom to choose which language to use on a process by process basis. And you can freely mix and match, even within a single composite. (A composite is the deployment unit in an SCA environment.) So why support both? Well it turns out that BPEL is really well suited to modeling some kinds of processes and BPMN is really well suited to modeling other kinds of processes. Of course there is a pretty significant overlap where either will do a great job What BPM adds to SOA Suite | RedStack
